Abstract

Facsimile reproducing appts. uses laterally-aligned beams (la,Lb,Lc) the line of alignment being at a small angle (theta) to the direction of scan. This angle may be varied, thereby varying the line pitch (P), when a high resolution scan is required. The beams are scanned over the surface of a drum, the angle (theta) being controlled by passing the fixed b3ams through an optical rotator on the beam producing device e.g. a semiconductor laser chip - which may be physically rotated. The beams are modulated via respective delays to take account of the differing positions of the beams in the direction of scan.

Description

Radiation recorder for the

Multiple Beam Recording The invention relates to a ray recorder for multi-ray recording in which a plurality of beams modulated with modulation signals onto a recording material are projected to thereby record information on the recording material.

In conventional recording devices for information recording onto a recording material, this is applied with a single beam for recording passed over or scanned; therefore, it is high for printing and recording Speed necessary, the speed at which the information signals are transmitted to increase the modulation of the beam.

It is also necessary to have the main scan or

to accelerate the scan in a main direction, so that therefore when using a rotatable or rotating polygon mirror for the main scan the speed of which must sometimes be greater than a few 1000 revolutions per minute; there is inevitably a structural limit for converting the device to a high speed recorder.

When for scanning a recording material the light beams from several light sources arranged in a row by means of a rotating polygon mirror, it is possible to use a high-speed recorder to obtain; however, if these beams are in a direction to the auxiliary scanning direction of the Recording material are arranged in the perpendicular direction, there is a disadvantage in that the distance between adjacent rays does not fall below a certain one Distance can be reduced.

To eliminate such a disadvantage, JP-OS 38130/1979 proposed a scanning device in which the recording material with several Rays is irradiated so that the rays are not perpendicular to the direction of the sweep or scanning of the recording material are arranged.

However, if the recording material is arranged with such an oblique Beams is scanned, the periods of time during which the respective Rays traverse the recording material; this leads to a complicated one Control of the recording and difficulties in making the recording in an accurate Able to bring about.

Further, if the information recording with such in the scanning direction offset beams occurs, the scanning pitch is in the direction of the Auxiliary scanning of the recording material by means of the beams through the arrangement of the multiple beams and therefore also when the main scanning speed is changed and the auxiliary scanning speed cannot be changed.

Therefore, for example, when using a single beam, the auxiliary scanning density can be doubled by doubling the main scanning speed and the High density, high quality recording with the. made by the same device while this is not accomplished when using multiple beams can be used unless the complicated interline system is used; thus it is difficult to use the same device with variable scanning pitch in the auxiliary scanning direction, high density and high quality recording to execute.

The invention is based on the object of a radiation recording device to accomplish. in which several beams are used and which makes it possible to use a very simple structure to accurately record the information.

The invention also addresses various shortcomings be turned off that occur when a recording material with several Beams is scanned obliquely in such a way that the arrangement direction of the beams and the scanning direction of the beams are not perpendicular to each other.

Furthermore, the invention is intended to create a radiation recording device that an accurate recording according to the deviation between multiple beams enables.

Furthermore, the radiation recording device according to the invention should Enable generation of precise sync signals corresponding to multiple beams.

Furthermore, in the radiation recording device according to the invention the recording density can be easily changed using multiple beams.

The invention is described below using exemplary embodiments Referring to the drawing explained in more detail.

In the apparatus shown in Fig. 1, 1 denotes a series semiconductor laser light source, in the case of FIG. 2 in a row with spacings A several light points a, b and c are arranged. The emission of rays from the luminous points a, b and c can be controlled separately by image signals from an image signal source 8.

This bundle of rays is generated by means of an optical condenser system 2 and enters an image erecting prism 60. The bundle of rays that has passed through the inverted image prism is twisted in its beam arrangement; the beam is projected onto a rotating polygon mirror 3; those of that Rotating polygon mirror 3 reflected rays are by means of an optical imaging system 4 imaged on a photosensitive drum 5.

The image rotating device or the image inverting prism will be described below described in detail with reference to FIG. 6. When the line segments 61 and 63 light rays are incident on the image erecting prism 60, which is in the 6A and 6B are shown (where the Fig. 6A is a side view and Fig. 6B is a plan view), the rays are refracted first, then by the base of the image inverting prism totally reflected and then refracted again so that they Rays result through line segments 62 and 64 shown are. In the case of total reflection, the rays are reversed with respect to the direction 61 and directed in the opposite direction to direction 62. Therefore, the excerpt in the direction 65 shown in FIG. 6C after passing through the image erecting prism 60 900 twisted in the direction 66. In one with respect to the direction 65 offset by e In the direction of 67, the section changes into one after passing through the image inverting prism Direction 68.

Therefore, when the luminous points a, b and c of the series semiconductor laser are arranged in the direction 65, the rays are caused by passing through the Image inverting prism pivoted by 900 in the direction 66. If the direction 66 to The scanning direction of the rotating polygon mirror is selected, the array semiconductor laser arranged perpendicular to the scanning surface. When the image erecting prism is at an angle e is rotated, the row semiconductor laser is rotated in the direction 67 relative thereto twisted and therefore the beam arrangement after passing through the erecting prism in the Direction 68 is pivoted so that it becomes that shown in FIG.

The light source 1 is close to the focus of the condenser optical system 2 arranged so that the rays a, b and c form an angle e (G = sin P P where M is the magnification of the entire condenser optical system and imaging system is) as shown in Fig. 3, which can be achieved by rotating the image erecting prism 60 adjustable pitch or

Line spacing P with respect to the circumferential surface F of the rotating polygon mirror 3 corresponds. The individual luminous point areas of the series semiconductor laser light source 1 can be viewed as point light sources because they are very small, such as B. something over 10 ßr. or fewer; several laser light sources can be provided which are collimated by means of the optical condenser system 2.

For example, if P. 100 µm, M =. 10 and A is 100 µm, is that Angle e very small; if P - 50 ijm, the angle G is even smaller; the cross section of the laser light beam falling on the rotating polygon mirror 3 is in the direction of perpendicular to the rotating surface F of the same is not very large and differs not much of a single beam. Accordingly, it is not necessary to to increase the thickness of the rotary polygon mirror 3 so that the same rotary polygon mirror as can be used for a single beam.

The multiple laser light beams reflected from the rotating polygon mirror 3 are deflected for scanning as shown in FIG. 4 and by means of the imaging system 4 imaged on the photosensitive drum 5. The distance between the luminous points is A, so therefore the distance between the mapped points is MA when the Magnification of the entire optical system M is. Furthermore, the angle is the turn the imaged points of the row laser in relation to the scanning area equal to 6, so that the pitch between the points shown is in the perpendicular direction for sampling equals MA sin e = P.

At the start of the scan, these several beams cross Lc, Lb and La a photodetector or radiation detector 7 in said order.

As described above, the scanning pitch is or line spacing by P = NA sin 9 given so that therefore the The scanning line spacing does not change even when the speed of the main scanning and the auxiliary scan is changed. This has led to the difficulty of finding a High density and high quality recording by doubling the scanning density in the same device.

In the embodiment of the radiation recording apparatus, the angle G made changeable by the fact that a beam pivoting element such as an image inverting prism or the like is used so that the scanning line spacing P is changeable, thereby eliminating the aforementioned disadvantage and to change the density in one and the same device, so that a recording of higher Density is enabled. The image signal source 8 in FIG. 1 is described below. In Fig. 5, BD denotes a radiation detector. In this embodiment the beams sweep over the beam detector BD with the beam switched on alone Lc, so that a single beam detection signal is output on a signal line SL1 is, which by means of a pulse shaping circuit WA in a short signal with a pulse-like Curve shape is formed.

Ca, Cb and Cc are counters. Ca is a counter for counting a number of times Na, the length of time after the beam Lc is detected by the beam detector BD until the actually cut-off beam La arrives at a recording start point WS on the photosensitive drum; Cb is a counter for counting one Number of cycles Nb, which is the length of time after the beam Lc is detected by the beam detector BD up to the arrival of the actually switched-off beam Lb at the starting point WS corresponds to; Cc is a counter for counting a number of cycles Nc, that of the length of time from when the beam Lc passes through one of the radiation detectors BD corresponding point up to the arrival of the beam at the recording start point WS corresponds.

These counters Ca, Cb and Cc start applying the beam detection signal to count; when they have counted the specific clock numbers Na, Nb or Nc, give they each send a control signal via signal lines SL2, SL3 and SL4 to control clock input circuits respectively.

-Switching elements Ca, Gb and Gc, each of which has a gate circuit, in order to generate a clock generator CLK on signal lines SL5, SL6 or SL7 Generate clock signal.

LBa, LBb and LBc are line buffer memories into which one scan line is stored corresponding point signal M is stored, which by means of the signal lines SL5, SL6 or SL7 applied clock signal synchronous with the applied clock signal is delivered to signal lines SL8, SL9 or SL10.

The point signal emitted in this way controls via driver circuits Da, Db and Dc are the light beam output from the luminous points a, b and c of the series semiconductor laser light source 1. CT is a counter that controls the switching on of the light beams so that when Scanning the radiation detector BD only the light beam Lc is switched on, while the other light beams La and Lb are switched off. The counter CT gives a switch-on signal on a signal line SL14 after having received one for the complete Irradiating the photosensitive drum 5 with all rays La, Lb and Lc sufficient Numerical value P has counted, and carries out Apply this switch-on signal at a terminal T1 of the driver circuit Dc the emission of the light beam Lc.

This counter CT is cleared by the beam detection signal, so that therefore the emission of the beam Lc is stopped as soon as the radiation detector BD detects the beam Lc. PEF is a page buffer where information is stored are stored, which are contained in at least one page or print page. From this memory, CONT are sequentially under the control of a control circuit generated character code signals belonging to a certain column and sent to a character generator CG is created, stored in the character dot pattern corresponding to this character code are; at the same time it is indicated by means of a signal on a signal line SL15, which line of this character dot pattern is to be delivered; thereby one becomes the selected line of the selected character dot pattern belonging to a point signal Signal line SL16 is formed and stored in a line data forming device LDF.

After in this way the point signals corresponding to one line have been stored in the forming device LDF, each one Line corresponding line point signals under the control of a distributor DIS stored in one of the line buffer memories LBa, LBb and LBc.

The following is the operation of the Strahlauf recording device with the structure described above. When the scanning or distracted Light beams with the arrangement shown in FIG. 4 on the radiation detector BD hit, with only the light beam Lc switched on (and where in Fig.

4 PBD indicates the location where the radiation detector is attached), the counter CT is cleared and the Counters Ca, Cb and Cc begin count the clock signals.

When the counter Cc has the number of cycles corresponding to the route lc in FIG Nc has counted and thus the imaginary ray Lc has counted the recording start point WS has reached, is controlled by the output of the counter Cc on the control clock switching element Gc, the output of the clock signals to the signal line SL7 began. The dot signals corresponding to a line are already in the line buffer memories LBa, LBb and LBc stored, so that, therefore, when the clock signal is applied, the Point signals are output to the signal line SL10 and via the driver circuit Dc the semiconductor laser is operated, whereby the output of the corresponding point signals modulated light beam Lc begins. Similarly, if the counter Cb the the number of cycles Nb corresponding to the distance lb counts, the reading out of the begins in the Line buffer LBb stored point signals, so that the transmission of the with these Point signals of the modulated light beam Lb starts. If equally the counter Approx. The number of cycles Na corresponding to the route la counts, the reading of the begins in the line buffer Lba stored point signals, so that the emission of the means this point signals modulated light beam La begins. The following applies here: Na> Nb > Nc.

With these in this way by means of the point signals from the three Line buffers LBa, LBb and LBc modulated three beams La, Lb and Lc being the photosensitive drum 5 scanned; the time pit at which the point signals are read out from the line buffer LBc is completed, is the time at which the beam Lc reaches a recording terminal WT; the times at which the readout of the dot signals from the line buffers LBb and LBa is completed the Zcitpunkte at which the beams Lb and La each reach the end point WT.

Even if after the readout of the dot signals from the line buffers has been completed LB clock signals are applied, point signals are no longer emitted, so that therefore, the light beams La, Lb and Lc are no longer emitted. Accordingly, it is done the emission of the beams La, Lb and Lc modulated by means of the point signals only between the recording start point WS and the recording end point WT. When the counter CT has counted the numerical value P and the light beams La, Lb and Lc have been deflected beyond the photosensitive drum 5 is sent to the A control signal is applied to terminal T1 in order to switch on the light beam Lc alone, while at the same time the control clock switching elements Ca, Gb and Gc by means of the control circuit CONT are controlled so that the application of the clock signals to the line buffers LBa, LBb and LBc is terminated. Until the time when the light beam Lc by means of the Radiation detector BD is detected, new point signals for the next recording stored in the line buffers LBa, LBb and LBc.

A change in the angle e will be described below.

In Figs. 7A and 7B, P denotes the line spacing; it was determined, that the image produced is practically flawless even if the line spacing deviates by the order of P / 8. It was also found that even one Deviation of the dots in the scanning direction in the order of 1/8 of the dot spacing (which is essentially equal to P) does not result in any difficulties, but rather for them practical Application is suitable.

Even if the angle of inclination is therefore due to an assembly error or the like e of the row arrangement erroneously becomes 8 as shown in FIG. 4 and in a deviation corresponding to P / 8 occurs in the direction perpendicular to the scanning direction, is when the row of rays is set at an angle e or less, in which the error β occurring in the horizontal direction is below an eighth of the point interval, there is no change in those corresponding to the rays Da, Lb and Lc Clock numbers Na, Nb and Nc are necessary, so therefore the data output using the same circuit structure is possible.

The angle e can be determined as follows: Da (where h is the deviation in the main scanning direction, 1 is the row arrangement interval (A), and M is the magnification of the scanning optical system), then: It can be seen from this that G c 48.8 ° applies. That is, if 3 5 is 48.80, even if the semiconductor laser wafer is mounted so that a deviation of P / 8 in the main scanning direction occurs on the recording surface, the deviation in the horizontal direction can be within one eighth of the point interval (P).

When the recording density changes to 2 times or 4 times the inclination 3 of the rays is changed according to the description below, however, it can be seen from the above equations that for, the deviation To keep t in the main scanning direction at P / 8 or less while increasing the recording density in the subscanning direction twice (decrease P to half) the condition 6 <-18.80 is sufficient and with an increase in the recording density in the auxiliary scanning direction to four times the condition 6 - <15.20 is sufficient.

If in the embodiment shown in Fig. 4 M = 10, A = 100 µm and P = 100 µm, e = 0.1 rad and therefore very small. If the The scanning line spacing is half as large, namely P = 50 μm, the angle e is still smaller, namely e = 0.05 rad.

Therefore, although the beam spacing in the main scanning direction in Fig. 4 equals MAcos 6, but the distance can be approximated with MA and as unchangeable be considered since 6 is sufficiently small. Figures 7A and 7B show the beam arrangement when reducing the angle o by half, namely to 6/2. In this case it will the scanning line spacing is also reduced to half, so that therefore the scanned line spacing is also reduced and recorded by means of the multiple beams nete width to the Half is reduced. Therefore, as the scan line spacing is decreased, the Main scanning speed increased twice or the auxiliary scanning speed reduced to half.

This is necessary for the scanning with the multiple beams run continuously, and takes place in accordance with the rotation of the Image erecting prism.

When the auxiliary scanning speed is reduced to half, the main scanning speed is not changed; thus there is some change of the beam spacing in the main scanning direction is negligible, so none Change the clock numbers Na, Nb and Nc corresponding to the beams La, Lb and Lc is necessary, whereby it is possible, according to the foregoing description, the To make data output with the same circuit structure.

On the other hand, when the main scanning speed is doubled, it is for Achieving the same segment 1 = Vs / f on the recording material when doubling Main scanning speed Vs necessary, the frequency f of the clock generator CLK after Fig. 5 to double.

Consequently, it is also necessary to make those corresponding to the rays La, Lb and Lc Choose counting numbers to 2Na, 2Nb and 2Nc. This must be in accordance with the Rotation of the image inverting prism take place. When setting the count numbers in this way it is possible to rotate the inverting prism with the same circuit structure adjust; if the scan line spacing is reduced to half it is when doubling the speed of the deflection device or scanning device, the count numbers corresponding to the plural beams and the data transmission clock frequency possible to achieve double density recording.

The above embodiment has been described with regard to the case that the inclination or ScrLraqlage of the rays by rotating the image inverting prism 60 is set or adjusted; it is also possible to adjust the inclination of the rays by rotating the light source without using the image erecting prism. to adjust.

8 to 11 show a light source device which is based on this Way is designed to be rotatable and as a series semiconductor laser light source 1 in Fig. 1 is applicable.

In Figs. 8 and 9, 11 denotes a condenser lens which is by means of a thread attached to its outer catch on a lens holder 12 and on this is fixed with the aid of a lock nut 13.

14 is a spring washer to eliminate any play the outer circumferential thread of the condenser lens 11.

15 is a series semiconductor laser chip for the delivery of several, beams La to Lc each modulated by means of a recording signal. That Laser plate 15 is glued to a carrier 16 made of thermally conductive metal, the is attached to a base made of thermally conductive metal. The laser plate 15 is sealed against the outside air by means of the base 17 and a cap 18 and shielded, which has an optical window 19 through which the light of the row laser is radiated toward the condenser lens 11.

Supply lines 20 to 24 protruding through the base 17 are on the electrodes of the laser 15 connected and via an intermediate plate 25 with a row laser driver circuit, not shown, is connected.

26 is a heat radiating plate that is used by the array laser radiates generated heat.

The cooling plate 26 is together with the base 17 by means of screws 27 and 28 attached to an adjustment plate 29 for adjusting the optical axis.

The adjustment plate 29 for adjusting the optical axis is with three screws that are essentially equally spaced on one on the optical axis of the condenser lens 11 are arranged centered circle (with additional for the screw 30 shown, two screws 30-1 and 30-2, not shown, are present are). connected to a tilt adjustment plate 31. One of the Screw 30 corresponding through hole 30a and two the other two screws Through holes 30a-1 and 30a-2 corresponding to 30-1 and 30-2 are sufficient larger than the screws 30, 30-1 and 30-2, so that therefore when loosening the screws the adjustment plate 29 for adjusting the optical axis with respect to the adjustment plate 31 is displaceable for adjusting the inclination or inclination, with a surface 29A illustrates a displacement surface. The surface 29A extends perpendicularly to the optical axis of the condenser lens 11. The tilt adjustment plate 31 is attached to the lens holder 12 with screws 32, 33 and 34, below substantially are arranged equidistantly on a circle centered on the optical axis; Furthermore, the lens holder 12 has a concentric to the optical axis Fitting section 35, which with a fitting opening 36 of the inclined position Adjustment plate 31 is engaged; therefore, when loosening the screws 32, 33 and 34, the inclined position adjustment plate 31 slightly in the area of slots 32a, 33a and 34a with respect to the lens holder 12 can be pivoted along the surface J, the fitting portion 35 serving as the axis of rotation. So that the tilt adjustment plate 31 can be pivoted, of course the through openings 32a, 33a and 34a formed in the lens holder 12 for screws 32, 33 and 34 take the form of arcuate slots leading to the mating portion 35 are concentric.

The lens holder 12 has threaded openings 37 and 38 for attachment the light source device on the basic structure of the information recording apparatus as well as fitting openings 40a and 41a for receiving dowel pins 40 and 41, which protrude from a light source holding part 39 of the recording apparatus.

In the light source device having the one described above The focus is set up or

Focusing of the condenser lens 11 by means of the on its outer circumference formed thread, while the so-called. Optical axis adjustment is possible in which the multiple light output areas of the array laser 15 are adjusted so that they are at with respect to the optical axis of the condenser lens 11 symmetrical locations lie; In addition, the focus and the optical lens adjustment can be used in the construction can be made independently of each other so that none of these settings are a Adjustment at the other setting results.

It is also used to incline the row arrangement of the scanning beams the tilt adjustment plate 31 coaxial with the optical axis of the lens holder 12 attached condenser lens 11 rotatable or pivotable.

Therefore, the row laser, in which the multiple light delivery areas are arranged in a row, swiveled and tilted at some angle so that the arrangement of the scanning beams can be easily arranged as shown in FIG Fig 3 can be tilted or inclined. The pivoting movement of the row laser takes place coaxially to the optical axis of the condenser lens, during the plane of the pivoting movement is perpendicular to the optical axis of the condenser lens; therefore, by the pivoting movement the above-described focusing and optical axis adjustment in none Way impaired.

In the embodiment described above, are coaxial to the optical axis of the condenser lens, the rotation fitting portion 35 and the fitting hole 36 provided; if, however, when assembling the light source device the optical axis of the condenser lens is actually set as the pivot axis, the fitting portion 35 and the fitting opening 36 can be omitted without any Difficulties arise in the adjustment described above.

The embodiment described above has a structure in which the condenser lens is fixed and the light source is pivotable; on the other hand Another embodiment shown in FIGS. 10 and 11 has a structure in which the condenser lens and the light source can be pivoted together, see above that is, therefore, in this embodiment in comparison with that described above Embodiment the possibility of adjusting the focus and the optical axis is further reduced by the pivoting movement.

In the embodiment according to FIGS. 10 and 11 the structure of the condenser lens and the light source is identical to that of the embodiment shown in Figs. 8 and 9, so that it is not described must become. In FIGS. 10 and 11, the same reference numerals as in FIG Figs. 8 and 9 are used.

10 and 11, the condenser lens 11 is on a plate-shaped Lens holder 50 attached.

A light source unit with the array laser 15, the cap 18 and the base 17 is together with the cooling plate 26 by means of screws 51 and 52 attached to the adjustment plate 29 for adjusting the optical axis and with the help of screws 53, 54 and 55 combined with the lens holder 50 to form a unit.

(The focusing of the condenser lens 11 and the optical axis adjustment of the light source unit are similar to those in the embodiment 8 and 9 and therefore need not be described).

A light source holder 56 is provided with an opening 56A which with the outer periphery 50A of the lens holder 50 coincides. The outer circumference 50A is coaxial with the optical axis of the condenser lens 11.

Accordingly, the lens holder 50 is relative to the light source holder 56 pivotable, the lens holder 50 is set by means of a stud 57.

The light source holder 56 is attached by means of screws 58 and 59 attached to the light source supporting part 39 of the information recording apparatus.

At 70 and 71 are on the light source support part 39 of the recorder attached dowel pins for Adjustment of the light source device marked in the right position.

In this structure, the condenser lens 11 and the light source unit constitute a unit pivotable in the fitting hole 56A of the light source holder 56; therefore, there is no possibility of being caused by the pivotal movement of the light source unit a deviation between the focal points or focus settings of the condenser lens 11 and the light source unit and an optical axis deviation occurs; furthermore, the beam arrangement angle can be adjusted in a very simple manner.

In the embodiments described above, the point in time at which the reading out of the picture element information from the line buffers LB is initiated is initiated in accordance with the inclination of the beams; as another However, the method can be read out from the respective line buffers independently of the inclinations of the corresponding beams are initiated simultaneously and the picture element signals read out in this way can correspond to the inclinations of the respective rays are delayed.

Such a delayed readout will now be described with reference to FIG. In FIG. 12, circuits having the same reference numerals as those in FIG Fig. 5 functions similar to the circuits in Fig. 5, while those with dashed lines Circuit parts framed by lines are different from those in FIG.

In Fig. 12, GT denotes a gate circuit; RCa denotes a Ring counter circuit, VCa denotes a gate control circuit and Ca, Gb and Gc designate the switching elements. On receipt of the output signal from the pulse shaping circuit WA begins the gate circuit GT, the output signal of a reference clock generator circuit or a clock generator CLK to the ring counter RCa.

The ring counter RCa has a modulo-N binary counter and is to the switching elements Ca, Gb and Gc, an output signal V which has N types of phases and that results from dividing the frequency of the output signal of the clock generator CLK by N gives. The pulse duration of the output signal V is equal to the pulse duration of a picture element. The function of the ring counter RCa will now be described in greater detail described.

The line buffer memories LBa, LBb and LBc provide one with clock signals synchronized data output. When the line buffers LBa, LBb and LBc with a clock signal be controlled, the distance xiAcov è between the neighboring shown in Fig. 4 must Luminous dots in the light beam scanning direction have an integer ratio Vs. c \ T, where Vs is the sampling rate and A T is the pulse duration of the clock signal. However, if the line buffers LBa, LBb and LBc match the one of the Ring counter RCa generated clock signal can be operated, which has N types of phases the distance MAcos 8 in the light beam scanning direction can be brought to Vs L \ T / N, where Vs is the sampling rate and # #T is the pulse duration of the clock signal with the N phase types. This means that the clock signal is used to detect irregularities of the distance MAcos 6 between the adjacent luminous points in the light beam scanning direction to correct to Vs ~ h bT / N.

Next, the switching elements Ca, Gb and Gc start by the output signal of the gate control circuit VCa including a counter or the like, the output signal of the ring counter RCa to the line buffers LBa, LBb and LBc.

The gate control circuit VCa divides the frequency of the output signal of the ring counter RCa by N, after which it sends a switching element switch-on command signal gives off to the switching elements Ca, Gb and Gc.

The function of the gate control circuit VCa described.

The beams La, Lb and Lc shown in Fig. 4 move after the detection of the beam Lc by means of the beam detector BD until the switch-on command signal is generated by the switching element control circuit VCa by the distance lD1. During this The duration is the delivery of the clock signal from the ring counter RCa to the line buffer LBa, LBb and LBc blocked.

That is, it can be done by the switching gate control circuit VCa the application of the clock signal from the ring counter RCa to the line buffer is blocked becomes, the amount of delay of delay circuits DL1, DL2 and DL3 by can be reduced to an extent corresponding to the route ID1. This means that the structure of the delay circuits DLI, DL2 and DL3 can be simplified.

By applying the clock signals from the switching elements Ca, Gb and Gc via the signal lines SL5, SL6 and SL7 become synchronous with the applied clock signals Point signals on the signal lines SL8, SL9 and SL10 read out.

Thereafter, the point signal read out on the signal line SL8 becomes applied to the delay circuit labeled DL1.

Assume that the point signal read out on the signal line SL8 forms the beam La shown in FIG. 4, that which is read out on the signal line SL8 Point signal by means of the delay circuit DL # for the period A T1 to Arrival of the beam La at the recording start point WS on the photosensitive Drum 5 delayed and then to the semiconductor laser modulation circuit or Driver circuit given since. The calculation of the time β # T1 will be described later.

It is also assumed that the read on the signal line SL9 Point signal forms the beam Lb shown in Fig. A, so on the signal line SL9 read out point signal by means of the delay circuit DL2 for the duration ß T2 until the arrival of the beam Lb at the recording start point WS at the photosensitive drum 5 and then to the semiconductor laser modulation circuit respectively.

Driver circuit Db delivered. The calculation of the time period t T2 is described later.

If one assumes in the further that the read out on the signal line SL10 Point signal forms the beam Lc shown in Fig. 4, so on the signal line SL10 read out point signal by means of the delay circuit DL3 for the duration n T3 until the arrival of the beam Lc at the recording start point WS at the photosensitive drum 5 delayed, after which it goes to the semiconductor laser modulation circuit or driver circuit Dc is transmitted.

AT1, AT2 and A T3 can be obtained from the following equations: If la '= la - ID1, # T1 = la' / Vs, where la is the distance from detection of the beam Lc by means of the radiation detector BD an until the arrival of the beam La at the recording start point WS is on the recording drum, ID1 is the Is the distance over which the beams La, Lb and Lc after detection of the beam Lc by means of of the radiation detector BD until a switching element switch-on signal is generated the gate control circuit VCa advance and Vs the scanning speed of the Rays La, Lb and Lc is.

Similarly, if lb '= lb-lD1, then BT2 = ib' / Vs; When lc '= lc-lD1, # T3 = lc1 / Vs.

In the exemplary embodiments described above, the other beams are switched off so that only one of the several beams is closed passed the radiation detector; in contrast, it is also possible to use the device to be trained in such a way that switching of several beams the selected beam arrives at the radiation detector.

According to FIG. 13, the output signal of the radiation detector 7 is determined by means of an amplifier 80, whose output signal is amplified by means of a threshold value circuit or level cutting circuit 81 is divided in terms of level. The cut level is determined by means of a potentiometer 82. This clipped output signal is output to a terminal 83. The radiation detector 7 contains a light receiving element, which is so dimensioned that it can absorb all rays at the same time, so that therefore the output signal waveform of the radiation detector 7 to the waveform according to FIG Representation is integrated in Fig. 14a. That is, if it differs from the representation in Fig. 4, the beams projected on the photosensitive drum 5 are four beams 15, t1 is the point in time at which a ray B1 begins to fall on the radiation detector 7, t2 a point in time at which a ray B2 is projected onto the radiation detector 7, t3 a point in time at which a beam B3 is projected onto the radiation detector 7 and t4 to t5 the period of time during which all rays B1 to B4 are projected onto the radiation detector 7.

At the time t5, the beam B1 leaves the radiation detector 7 to At time t6, the beam B2 leaves the radiation detector 7, at time t7 the beam B3 leaves the radiation detector 7 and at the time t8 the beam B4 leaves the radiation detector 7, after which no more beam is projected onto the radiation detector 7 will In this embodiment, the timing of the rise becomes of the first, incident on the radiation detector 7 beam in the form of a detection signal determined and from this detection signal in each case one beam Position signal or time signal generated as shown in FIGS. 14c to 14f.

The details of this circuit part are illustrated in FIG. 16 described.

The level cut output (FIG. 14b) at that shown in FIG Terminal 83 is applied to terminal 90. The signal represents a cancellation signal of a counter 91, the counter only counting in its high range executes. The counter 91 counts the clock signal from a quartz oscillator 92, the Frequency f1 higher than the image recording clock frequency f2 of the recording device is (f1 = n.f2). U.S. Patent 4,059,833 states that "shaking" of the The higher this oscillator frequency, the more the image is reduced.

The time signal 1 shown in FIG. 14c is generated by means of a flip-flop 93 generated. When the level cut output goes high, it goes high Output of flip-flop 93 is high. At the same time the counter starts 91 to count the clock signals from the crystal oscillator 92. The output signal of the Counter 91 is a parallel multi-bit output that is sent to comparators 94 to 100 is created (such as an Comparator SN 7485 from Texas Instruments Inc.).

The comparison input signals of the comparators are by means of a Switch group 101 preset so that, for example, as shown in the illustration Numerical value M is applied to the comparator 94, a numerical value N1 to the comparator 95 is applied, a numerical value N1 + M is applied to the comparator 96, etc.

When these preset values with the output of the counter 91 match, the output signal of the relevant distributor goes high on so that a flip-flop is switched.

If at the time signal 1 by counting the numerical value M by means of of the counter 91, the coincidence output of the comparator 94 is generated the flip-flop 93 is reset so that the output signal shown in Fig. 14c is output will. In the case of the time signal 2, a count value N1 is counted by means of the Counter 91 from the comparator 95 a coincidence output for setting a Flip-flops 102 delivered while counting N1 + M by means of the counter 91 from the comparator 96 a coincidence output signal for resetting the flip-flop 102 and generates an output signal as shown in FIG. 14d will.

Thereafter, a flip-flop 103 is similarly made by counting set by N2 by means of the counter 91 and by counting N2 + M by means of the Counter 91 reset and a flip-flop 104 by counting N3 by means of the Counter 91 is set and by counting N3 + M by means of counter 91 back- set.

It is important for the time signals 1 to 4 that their time of rise and their duration is appropriate.

The increase must correspond to the increasing part of the figure shown in Fig.

14a can be brought into correspondence with the staircase-like signal shown Therefore, for the adjustment of the rise part with respect to the time signal, ~ 2 to 4 shows the signal according to FIG. 14a and the respective time signal on an oscilloscope made visible. The setting is made by changing the default values N1 to N3 of switch group 101.

In Fig.14, image clock signals 1 to 4 are with a certain mutual Phase relationship shown, however, correspond of course due to the dependency of the count values N1 to N3, the phases of the image clock signals 1 to 4 are not the ones shown.

When the light rays completely cross the radiation detector 7 the level cut output (Fig. 14b) goes low so that the counter 91 is cleared and its counting operation is ended. In this embodiment becomes the width of the time signals by using the flip-flops 93, 102, 103 and 104 determined; if this part of the circuit is replaced by monostable multivibrators, however, the reset circuits for the flip-flops and thus the reset comparators can 94, 96, 98 and 100 can be omitted.

Furthermore, in this exemplary embodiment, the delay takes place Signals by means of the counter 91; however, it is of course also possible to delay to use multiple monostable multivibrators of the signals; such a thing The embodiment is shown in FIG.

A single-pulse circuit or monostable multivibrator 111 'for generation of the time signal 1 and monostable multivibrators 112 'to 114' for the signal delay are triggered by means of a level cut signal (shown in FIG. 14b) which is applied from a terminal 110 '. The output signal of the monostable multivibrator 111 'results in the time signal 1 (FIG. 14c).

The level cut signal is generated by means of the monostable multivibrators 112 'to 114' delayed, after which there are monostable flip-flops 115 'to 117' for the Time signal generation triggers the time signals to the in Figs. 14d, 14e and 14f illustrated shapes.

Instead of the monostable multivibrators for the signal delay you can other delay elements such as ultrasonic wave delay lines are also used will.

According to the description above, the time of arrival becomes the first beam is detected at the radiation detector 7; on the other hand there is no Restriction to such a design, so that by increasing the Cut level indicates the time of arrival of the second or third ray the radiation detector can be detected and these signals to generate the time signals 2 to 4 can be delayed.

Fig. 18 is a block diagram showing a circuit for beam position detection and information signal processing in one embodiment of the recording apparatus shows.

Fig. 18 shows an input signal generating circuit with which receive the time signal 1 of FIG. 14 and a signal from a character generator is entered into a shift register. 92 denotes a quartz oscillator with a frequency n times that of the image clock signal shown in Fig. 14, 105 denotes an AND circuit, 93-1 denotes a signal line for input of the timing signal 1 shown in Fig. 14, 106 denotes a flip-flop, 107 denotes a counter for decreasing the frequency of the applied signal to 1 / n, 108 denotes a counter for the reduction of the applied signal to 1 / m and 109 denotes a counter for decreasing the frequency of the applied signal to 1/1.

The time signal 1 shown in Fig. 14 is applied to the AND gate 105, formed by its AND operation with the output signal of the oscillator 92 to set flip-flop 106. Its output signal 106-1 is applied to the switching input terminal of the 1 / n counter 107 is applied, which receives the clock signals with the frequency f1 from the oscillator 92 counts. Its output signal is determined in terms of frequency by the counter 107 is reduced to 1 / n times and gives an image clock signal 107-1 with the frequency f2. This image clock signal is then applied to the 1 / m counter 108. In this case m is equal to that generated in parallel when the character generator (110 in FIG. 20) is queried Number of picture elements and, for example, m = 8 if eight points are at the same time be generated. Accordingly, the output signal 108-1 of the counter 108 is on Signal that is emitted for every m points and is used when the m-bit output signals of the character generator can be entered into shift registers (111 to 114 in Fig. 20).

Likewise, this is reduced to 1 / m in terms of frequency Signal 108-2 applied to 1/1 counter 109. The value of 1 indicates how many m-bit point units are present in one line; if, for example, a line is made up of 1600 points and the output of the character generator is output in 8-point units becomes, 1 = 200. The output of this counter 109 is applied to the reset terminal of the flip-flop 106 is applied to reset it, whereby the switching inputs of the Counters 107 to 109 are locked while they are cleared at the same time.

In this way, charging pulses or input pulses 107-1, 108-1 and 109-1 which constitute the image signals for one line.

The curve (f) shows the output signal of the 1/1 counter 109, with which the signal according to (c) is switched off, by switching off the counters 107, 108 and 109 locked and deleted.

The control circuit 119 causes the code signal to be stored 120-1 from an external device (not shown) into the code memory 120; when a the desired amount of data is reached, the control circuit puts it in one line the code sequence, after which the character generator 110 interrogates successively will. The character generator 110 is a conventional character generator in which the Dot matrix patterns corresponding to code signals are stored; when the code signal and the line signal (scanning line signal) are applied to the character generator, becomes a certain point signal with m points output in parallel. The output signal 120-2 from the code memory 120 is a code signal, while the Output signal 118-1 of the line address counter or

Line counter 118 becomes a line signal. On the other hand, that will The output signal of the radiation detector 7 is applied to the time signal generator 115 the timing signals 115-1 to 115-4 in this way as shown in FIG. 16 which are applied to the input signal generator 116. Therefore, according to 18, image clock signals 116-5 through 116-8 (of which the signals 116-6 to 116-8 correspond to the time signals 2 to 4) and input signals 116-1 to 116-4 generated (of which the signals 116-2 to 116-4 correspond to the time signals 2 to 4), these signals to the parallel / serial conversion shift registers 11 1- to 11 4 can be created. On the other hand, the load signals or input signals 116-1 to 116-4 applied to the OR gate 117 and then applied to the line counter 118. The count of the line counter 118 is determined by the input signals 116-1 to 116-4 renewed or refreshed; with each new count, the output signal of the Character generator 110 is input to the shift registers 111-114. With every renewal of the code signal 120-2 by means of the control circuit 119, the line counter 118 becomes preset to its initial state by means of a signal 119-2. In detail the input signals 116-1 to 116-4 from the input signal generator 116 in FIG their phase is delayed by N1, N2 and N3, respectively, as shown in FIG.

Accordingly, when the OR signal from the signals 116-1 to 116-4 the Update line counter 118 and call character generator 110 its output signal is transferred to the shift register by means of signal 116-1 111 input, input to the shift register 112 by means of the signal 116-2, input to the shift register 113 by means of the signal 116-3 and by means of the Signals 116-4 into the sliding register 114 entered. on the other hand The signals 116-5 to 116-8 are image clock signals with which the into the shift register 111 to 114 input signals can be converted into serial signals. The control circuit 119 causes the number of line dots of the dot matrix pattern of the character generator 110 is temporarily stored in the buffer memory 125. One from the input signal generator 116 generated single cell - completion signal 116-9 causes the counter 127 a Addition of "4". In FIG. 20, four row lasers are chosen as an example; at M row lasers instead add ~ M "to the counter 127 Comparator 126 compares the number of row points of the dot matrix pattern the buffer 125 with the count of the updated Line counter 127; when the two values become equal to each other, is determined by the comparator the counter 127 is cleared while at the same time sending a signal to the control circuit 119 gives away. This completes a character or pattern corresponding to a code signal is equivalent to. Determined each time the code signals are renewed in a line (120-2) the control circuit 119 the count of the counter 127 and sets the line counter 118 via the signal line 119-2. Thus, the line counter 118, which is the character generator 110 queries, set in its count value each time the code is renewed, so that therefore the characters or patterns are correctly arranged and output in a line.

The signals of the shift registers 111 to 114 are respectively sent to the Laser driver stages 121 to 124 are applied to thereby the light source or laser arrangement 1 to be controlled. With their rays, as shown in FIG. 1, the information recorded on the photosensitive drum.

Thus, in the described embodiment, when several recording beams are not arranged perpendicular to the scanning direction are mutually phase-shifted image signals generated by the beam detection signal and a pulse can be combined with a frequency n times as large as that Frequency of the image clock signal; thereby the following is achieved: 1. The point deviation can be held down to 1 / n of a point; and 2. the character generator (in which stores the dot matrix-like pattern for generating a character or pattern is) is queried directly, so that therefore the image signals with a simple structure can be generated.

The aforementioned embodiment has been made about a case described that the recording of the information using all of the several Rays takes place; alternatively, however, it is possible to adjust the scan line density by using all or only some of the plurality of beams.

Level cut circuit.

The control circuit 130 causes code signals 131-1 from a External device (not shown) can be stored in the memory 131. if a certain amount is reached, the recording of the information is initiated the dot pattern generator is queried. First is the first code signal of a line is applied to the dot pattern generators 133 and 134. If according to this code signal a control code has been generated which commands high density recording, the control code is applied to the special code detector 132. If a special code or if a certain special code or designation code is determined, a Signal 132-1 is generated to use dot pattern generator 134 for recording high density. On the other hand, no signal 132-2 is generated, so that the normal density dot pattern generator 133 remains inoperative. Further the detection signal 132-1 is applied to the switching element 136, so that from the from the oscillator circuit 135 output image clock signals with clock signals 135-2 high frequency are selected, synchronized with an image position detection signal 145 and to the shift register 13-7 to 140 can be created. The control circuit 130 supplies the dot pattern generators 133 and 134 with the code signal 131-1 and gives at the same time under time control with the beam position detection signal 145 (which is essentially synchronous with the period of passage of the respective Beams at the radiation detector is) successive signals 130-1 to 130-4 for inputting the signals from the dot pattern generator 134 into the shift registers 137 to 140. The signals input to the shift registers 137 to 140 become converted into serial pixel signals by means of the selected image clock signal 136-1 and applied to the driver stages 141 to 144 in order to drive the light source 1 and thereby to record the information on the drum 5.

On the other hand, when there is no special code from the special code detector 132 is detected, no detection signal 132-1 is generated, but instead a non-detection signal 132-2 to thereby supply the dot pattern generator 133 for normal To put density into operation.

Since no detection signal 132-1 is generated, the gate selects 136 takes the image clock signal with the low frequency and puts it under timing control with the radiation position determination signal 145 to the shift registers 137 to 140. The output of the normal density dot pattern generator 133 is sent to the Parallel / serial conversion shift registers 137 and 139 applied. The control circuit 130 causes input pulses 130-1 and 130-3 to be applied to the shift registers 137 and 139 under time control with the radiation position determination signal 145. These Pulses are converted into serial pixel signals that are used to operate the multiple Beam generators or the light source are applied to driver stages 141 and 143 will. In the driver stages 142 and 144 from the shift registers 138 and 140 no image signals are input, so that no demented speaking Rays are generated; thereby the radiation density, namely the scanning density to a normal density.

Thus, in the embodiment described, the designation or special signal is determined and accordingly one of the several to be controlled Beams selected and the frame rate changed, making it easy a high density pattern is recorded in any position of single page information can be. Although the normal density dot pattern generator 133 and the high density dot pattern generator 134 is used as dot pattern generators, however, it is also # possible to use the normal density dot pattern generator 133 alone used to record the same point twice.

As an example of several rays, four rays have been chosen here, however, the number of beams can be two or more. Furthermore, if the number of the rays is equal to n and nPS2 is the normal pixel spacing, becomes at while in normal density mode a single beam is put into operation of the high density mode every n beams are activated and the Image clock frequency is increased to n times, so that a pattern of picture elements whose density is n times that of the normal density mode is obtained. It is true that the scanning line density and the density in the scanning direction became simultaneous changed, but only one of the densities can be changed with regard to of the high density image is effective. The high density recording can be performed without any Time delay accomplished anywhere in the single page data the quality of the printing or the on drawing can be increased.
