Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a certificate printing and issuing device for printing and issuing, for example, a resident's card in a local government, various certificates in a university or other educational institution, and in particular, a printing unit for printing a predetermined form part. Further, the present invention relates to a certificate printing and issuing device having a configuration in which a printing unit for printing certification for example by embossing is connected and having a function of discharging a plurality of certificates at the same time or collectively.

[0002]

2. Description of the Related Art Conventionally, in the case of issuing a resident's card in a local government or various certificates in a university or other school institution, most of the cases have been to extract the original, copy it, and then print it with a seal or certification stamp. In addition, many of these issuance tasks were done manually, and it took a long time from the request for certificates to the issuance of prints.

In recent years, a device having a function of automatically printing and issuing various certificates from a pre-stored database by computer control has emerged, and the conventional manual work is greatly reduced, and from the request to the printing issuance. The time required is becoming shorter.

[0004]

However, in the above-mentioned conventional apparatus, the content of the predetermined format is only printed and issued, and the proof mark is still by hand, and the proof portion is printed by embossing or the like. In most cases, the devices are installed separately, and the claimant of the certificates complains that the waiting time is long.

Further, even when a plurality of certificates are printed, as a result of being discharged to one sheet, a dedicated stacker is required, and there is a problem that the whole apparatus becomes large and complicated. When a plurality of sheets are stored in a stacker or a storage unit, it is necessary to have a means for preventing dissipation due to wind or the like at the time of storage. As this means, for example, a roller biased by a spring or the like is used to lightly press the sheets. There is something.

FIG. 16 is an explanatory view showing an example of a sheet pressing means provided near the sheet discharge port of the sheet conveying mechanism in the conventional apparatus. In FIG. 16, reference numerals 101 and 102 denote an upper guide and a lower guide, respectively, which are provided to face each other with a slight space therebetween to form a sheet conveyance path and guide the sheet in the arrow direction. Denoted at 103 and 104 are rollers for carrying, respectively, for nipping the paper and ejecting it to the ejection port 105. Reference numeral 106 denotes a pressure roller, which is pressed against the lower guide 102 by a spring 107, for example.

With the above structure, the pair of rollers 103,
A sheet (not shown) is nipped and conveyed in the left direction of the arrow by rotating 104 in a state of abutting. When the leading edge of the paper slightly protrudes from the discharge port 105, the roller 1
The rotation of 03 and 104 is stopped, and the roller 103 is retracted upward as shown by the arrow. In this case, the sheet is pressed against the lower guide 102 by the pressure roller 106, and thus is held without being blown by wind or the like. When the claimant or the user pulls out the paper by holding it, the pressure roller 106 rotates as the paper is pulled out, and the paper is discharged.

However, when the pressure roller 106 as shown in FIG. 16 is provided, the roller 103 for conveying the sheet is provided.
It is necessary to provide a means for canceling the paper sandwiched state, which complicates the apparatus configuration. In addition, since the pressure roller 106 is always present in the paper conveyance path, there is a problem that the paper conveyance may be hindered.

The present invention solves the problems existing in the above-mentioned prior art, and with a relatively simple structure, it is possible to automatically issue certificates of the number of sheets requested by the claimant simultaneously or collectively. An object is to provide a print issuing device.

Next, in a second aspect of the present invention, in the first aspect of the present invention, an upper guide and a lower guide are provided in the vicinity of the sheet discharge port of the sheet conveying mechanism so as to face each other, and the upper guide and the lower guide are respectively used for sheet conveyance. The rollers of
The lower guide is formed so as to be rotatable via a fulcrum provided near the paper discharge port, and the opposing rollers for conveying the paper are formed so as to be disengageable, and printing is performed between the upper guide and the lower guide. We adopted the technical means of forming a temporary stacking part of the formed paper.

According to a third aspect of the present invention, in the second aspect, the lower guide and the fulcrum are formed so as to be disengageable, and the lower guide is rotatable about the upstream end of the lower guide in the sheet conveying direction as the fulcrum. We adopted the technical means of forming.

Further, in a fourth aspect of the present invention, in the second aspect of the present invention, a protrusion is provided in the vicinity of the sheet discharge port of the lower guide, the protrusion facing between the plurality of rollers for sheet conveyance provided in the upper guide. A roller provided on the guide and facing the roller provided on the upper guide is formed to be retractable, and the printed sheet is sandwiched between the roller provided on the upper guide and the projection provided on the lower guide. We adopted the technical means of forming as much as possible.

Next, in a fifth aspect of the invention, in the first aspect of the invention, a rotatably formed link is provided in the vicinity of the sheet discharge port of the sheet conveying mechanism, and the sheet discharge port is provided at the rotating end of this link. Is provided with a shutter for opening and closing, a passage switching guide and a reject stacker facing the passage switching guide are provided in an intermediate portion of the sheet conveying mechanism, and a sheet conveying roller provided between the passage switching guide and the sheet discharge port. Is adopted so that the printed sheets can be discharged to the reject stacker.

[0015]

With the above construction, in the first aspect of the invention, the claimant inputs predetermined information from the input section, and the control section operates each of the constituent sections based on this information. That is, the certification content is printed on the paper by the first printing unit, and then the certification printing is performed by the second printing unit and is stored in the paper transport mechanism. Then, after the printing for the predetermined number of issued sheets is completed, these sheets are simultaneously or collectively conveyed and discharged.

Next, in the second aspect of the invention, the printed sheets are temporarily stored in a temporary stack portion formed by an upper guide and a lower guide provided in the vicinity of the sheet discharge port until a predetermined number of sheets are reached, After the predetermined number of sheets of paper have been stored, the upper guide and the lower guide are closed to bring the opposed rollers for conveying the paper into the engaged state, and the paper is ejected simultaneously or collectively from the paper ejection port.

According to the third aspect of the invention, when the paper is jammed undesirably in the temporary stack formed by the upper guide and the lower guide, the lower guide is rotated with the upstream end of the lower guide in the paper conveying direction as a fulcrum. By moving, the downstream side of the upper guide and the lower guide in the sheet conveying direction is opened, so that the jammed sheet can be easily removed.

Further, in the fourth aspect of the invention, the lower guide is rotated when the leading edge of the sheet reaches the sheet discharge port, thereby releasing the engaged state of the roller pair for sheet conveyance and conveying the sheet. Suspend. On the other hand, the rotation of the lower guide causes the protrusions provided on the lower guide to slightly enter between the plurality of rollers provided on the upper guide, so that the vicinity of the leading end of the sheet can be lightly held in a comb shape. ， It prevents the dissipation of the paper.

Next, in the fifth aspect of the present invention, if the printed sheet corresponding to the billing content of the claimant is on standby in a state of being slightly projected from the sheet discharge port, the billing is performed even if a predetermined time elapses. If a person does not take out the paper, it will not only hinder the subsequent service, or the next paper will be conveyed into the paper conveyance mechanism and jamming will occur, so that the paper is ejected to the reject stacker. At the same time that the printed sheet stands by near the sheet discharge port, the passage switching guide provided in the sheet conveying mechanism operates, so that the sheet is smoothly discharged to the reject stacker by the reverse rotation of the sheet conveying roller. After the discharge is completed, the path switching guide is restored, and a regular sheet transport path can be secured.

Next, the operation of the above structure will be described. In FIG. 1, first, when a claimant who requests the issuance of a certificate inserts an ID card into the reading unit 11, the reading unit 11
Reads the ID card and confirms the personal identification number input from the input unit 12 via the control unit 15 and the communication unit 16 by the central control unit. Next, the certificate print issuance is performed based on the information input from the input unit 12. The input information from the input unit 12 is displayed on the display unit 13.

The paper printed in the predetermined format in the first printing unit 1 is transferred to the second printing unit 2 by the paper transport mechanism 3.
Then, the certification mark is printed by, for example, emboss printing, and is stored in the temporary stack portion 7 formed by the upper guide 5 and the lower guide 6. When printing of the number of sheets requested by the claimant is completed, the lower guide 6 rotates counterclockwise, and the upper guide 5 and the lower guide 6 are rotated.
A pair of rollers (not shown) for transporting a sheet, which are provided so as to face each other, come into contact with each other, and the printed sheets are collectively transported to the sheet discharge port 4 until the leading end thereof is projected and stopped. .

Next, when a predetermined fee is stored in the money storage unit 14, the printed sheets are collectively discharged via the sheet conveying mechanism 3. In this case, when the sheet stopped by partially projecting to the sheet discharge port 4 is not discharged within a predetermined time, the path of the sheet is switched by the path switching guide 9 and the backward transport action of the sheet transport mechanism 3 is performed. Then, the printed paper is discharged to the reject stacker 8. After the paper is completely discharged, the path switching guide 9 is returned to prepare for the next paper transportation.

At this time, the memory in the control unit 15 adds one (25) to the number of sheets temporarily stored in the stack unit.

Next, it is confirmed whether or not all the sheets requested by the claimant have been printed (26). If printing has been completed, the temporary stack portion storage portion is discharged (28) and the processing is finished (29). If the printing has not been completed, the requested number of sheets, that is, the batch ejected number, is compared with the number of sheets stored in the temporary stack unit (27). If the above numbers match, the temporary stack portion storage amount is discharged (28), the temporary stack portion storage number is set to 0 (22), and the steps after step 22 are repeated. On the other hand, when the numbers of the two do not match, the above steps 23 to 26 are repeated, and after the predetermined number of sheets are stored in the temporary stack section, the sheet conveying mechanism 3 shown in FIG. The discharged sheets are collectively discharged (28), and the process is ended (29).

In the above embodiment, an example in which the batch discharge unit of sheets is designated by the number of sheets is described, but a control mode may be designated by time. That is, for example, if "90 seconds" is designated, the printed sheets stored in the temporary stack section 7 shown in FIG. 1 can be collectively discharged every 90 seconds. If you do this, you will not experience a feeling of frustration no matter how many seconds you wait.
It is easy to make a standard such as. Further, in consideration of the storage capacity of the temporary stack unit 7, it is also possible to adopt a batch discharge method in which time or the number of sheets is combined as a unit.

FIG. 3 is an explanatory view showing the construction of the sheet conveying mechanism 3 shown in FIG. 1 in more detail. The same parts are designated by the same reference numerals as those in FIG. In FIG. 3, the paper transport mechanism 3

It is composed of an upper guide 5 and a lower guide 6 provided. These guides are provided with rollers 34 and 35 for conveying the paper, respectively, and one of them is a driving roller and the other is a driven roller, and the driving roller is driven by a paper conveying motor 36. To do.

Next, 37 to 40 are sensors for detecting the leading edge and the trailing edge of the paper.
1, the sensor 38 is located on the carriage forming the second printing unit 2, the sensor 39 is located near the paper discharge port 4, and the sensor 40 is located on the path switching guide. Provided in the vicinity of 9, respectively. Reference numeral 41 denotes a shutter, which is provided in the vicinity of the paper discharge port 4 and is provided with the paper discharge port 4
To be openable and closable. Reference numerals 42 and 43 denote reject rollers, which are provided in the vicinity of the passage switching guide 9 so as to form a pair.

Reference numerals 44 and 45 are solenoids. The solenoids 44 and 45 are connected to the operating rod of the solenoid 44 and the upstream end of the lower guide 6 in the sheet conveying direction so that the lower guide 6 can be rotated. The rod is connected to a link (not shown) to be described later, and the shutter 41 and the passage switching guide 9 can be interlocked to operate via this link. Reference numeral 46 denotes a lock claw, which is rotatably provided on the downstream side of the lower guide 6 in the sheet conveying direction and is releasably engaged with a rotation fulcrum 47 of the lower guide 6.

Next, the operation of the above structure will be described. First, the solenoid 44 is released, and the lower guide 6
Is rotated clockwise through a rotation fulcrum 47 to form a temporary stack portion 7 between the upper guide 5 and the lower guide 6. Next, when the sheet printed in the predetermined format by the first printing unit 1 is ejected in the direction of the arrow and the leading edge of the sheet is detected by the sensor 37, the sheet conveying motor 36 operates and the rollers 34, 35 Rotates, and the guides 31 and 32 convey the above-mentioned sheet at a speed synchronized with the discharge speed of the first printing unit 1.

When the trailing edge of the sheet passes the sensor 37 or the leading edge of the sheet is detected by the sensor 38 (for example, in the case of a large-sized sheet of B4 size), the rollers 34 and 35 rotate at high speed. , The paper is conveyed at high speed to the imprint position of the second printing unit 2. In the second printing unit 2, the sensor 38 provided on the carriage detects, for example, the left edge of the paper, and moves the imprint head including a dot printer or the like to a predetermined imprint position to perform imprint or emboss for certification. Print. Next, the printed sheets are conveyed and stored in the temporary stack unit 7, and after the predetermined number of sheets are stored, the lower guide 6 is rotated counterclockwise by the urging of the solenoid 44, and the rollers 34 and 35 eject the sheet discharge ports. It is discharged from No. 4. In this case, the paper outlet 4
Needless to say, the shutter 41 moves upward and is opened by the urging of the solenoid 45.

4 to 5 are views for explaining the operating state of the lower guide 6 shown in FIG. 3, and the same portions are the same as in FIG.
The same reference numerals are used. In these figures, 51 is an operating rod and 52 is a link. The link 52 has a substantially L shape,
The pin 53 is rotatably formed through the pin 53 and is connected to the operating rod 51 through the pin 54. The link 52 is connected via a pin 55 to the upstream end of the lower guide 6 in the sheet conveyance direction.

First, FIG. 4 shows a state in which the upper guide 5 and the lower guide 6 form a temporary stack portion 7. That is, when the solenoid 44 is released, the operating rod 51 projects from the solenoid 44 and rotates the link 52 in the counterclockwise direction via the pin 53.
Rotate clockwise around. Therefore, it is possible to form the temporary stack portion 7 between the upper guide 5 and the lower guide 6 in which sheets can be stored.

In this case, since the roller 35 is provided on the lower guide 6, the engagement state with the roller 34 provided on the upper guide 5 is released by the rotation of the lower guide 6. Therefore, for example, even if the roller 34 rotates as a driving roller, the roller 35 does not rotate.

FIG. 5 shows a mode in which the upper guide 5 and the lower guide 6 are brought close to each other to bring the sheet into a conveyed state. That is, the solenoid 44 is biased to suck the operating rod 51. Since the link 52 rotates clockwise through the pin 53 due to the suction of the operating rod 51, the lower guide 6 moves the link 5
It is pushed up by 2 and rotates counterclockwise around the rotation fulcrum 47. Therefore, since the rollers 34 and 35 sandwich the sheet, the roller 35 is driven by driving the roller 34, and the sandwiched sheet can be conveyed toward the sheet discharge port 4.

FIG. 6 shows a state in which the lower guide 6 is opened on the side of the sheet discharge port 4. That is, when the lock claw 46 shown in FIG. 4 is rotated counterclockwise around the pin 57 via the lever 56, the lock claw 46 is disengaged from the rotation fulcrum 47. Therefore, the lower guide 6 can be rotated counterclockwise around the pin 55, and the state shown in FIG. 6 can be obtained. This makes it possible to easily remove the jammed paper between the upper guide 5 and the lower guide 6. Further, by opening the lower guide 6 as shown in FIG. 6, it is possible to easily perform work such as maintenance and inspection of the internal components of the upper guide 5 and the lower guide 6.

FIG. 7 and FIG. 8 are enlarged explanatory views of the essential parts showing the vicinity of the sheet discharge port 4 of the sheet conveying mechanism 3 in another embodiment of the present invention, and the same portions are the same as those in FIG. 3 to FIG. Are indicated by reference numerals. In FIGS. 7 and 8, 61
