<Configuration of image pickup device>
First, the configuration of the image pickup apparatus 1 will be described (see FIGS. 1 and 2).

The image pickup apparatus 1 is composed of an apparatus main body 2 and a display panel 3 (see FIG. 1).

The device main body 2 is composed of required parts arranged inside and outside the outer casing 4. On the outer casing 4, for example, various operation units (not shown) are arranged on the upper surface and the rear surface. As the operation unit, for example, a power button, a shutter button, a zoom knob, a mode switching knob, and the like are provided.

A mount portion 5 on which an interchangeable lens is mounted is provided on the front side of the device main body 2. An image pickup device (not shown) such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor) is arranged inside the outer casing 4, and the image pickup device is located on the rear side inside the mount portion 5.

A viewfinder 6 is provided at the upper end of the device main body 2. A viewing window 6a is provided at the rear end of the viewfinder 6 so that the user can look into it during shooting or the like. The viewfinder 6 is capable of switching between a usable mode and an unusable mode. When the viewfinder 6 is set to the usable mode, the viewfinder 6 is energized, and the user can look into the viewing window 6a and visually recognize the state of the subject by the viewfinder 6 to take a picture. .. On the other hand, when the viewfinder 6 is set to the unusable mode, the viewfinder 6 is not energized.

An eyepiece sensor 7 is arranged at the rear end of the device main body 2 at a position immediately below the viewing window 6a. The eyepiece sensor 7 has a function of detecting the presence of an approaching object when the object approaches. Therefore, when the user approaches the eyepiece sensor 7 to a certain distance in order to look into the viewing window 6a with the intention of using the viewfinder 6 at the time of shooting or the like, the detection operation of the eyepiece sensor 7 is disabled. Except for the case, the eyepiece sensor 7 detects the presence of the user, and the viewfinder 6 is set to the usable mode. On the other hand, if the user stops using the viewfinder 6 at the end of shooting or the like and moves away from the eyepiece sensor 7 by a certain distance, the eyepiece sensor 7 will not detect the presence of the user, and the viewfinder 6 will not be able to detect the presence of the user. Set to unusable mode.

The accommodating portion 8 is formed in the apparatus main body 2, and the accommodating portion 8 is formed in a concave shape that is opened at least rearward. The display panel 3 is accommodated in the accommodating portion 8.

One side portion continuous with the accommodating portion 8 of the apparatus main body 2 is provided as shaft support portions 2a and 2a separated vertically. A first hinge shaft, which will be described later, is rotatably supported on the shaft support portions 2a and 2a.

The display panel 3 is openable and closable with respect to the device main body 2 and is rotatable in a direction different from the opening and closing direction. The display panel 3 has a panel body 9, a first hinge shaft 10 and a second hinge shaft 11 (see FIG. 1).

The panel main body 9 is formed in a flat rectangular shape, and has a display unit 12 on one surface side in the thickness direction. As the display unit 12, for example, a liquid crystal display (Liquid Crystal Display) is used.

The first hinge shaft 10 is continuously provided at one end of the panel main body 9, and the axial direction is up and down. The first hinge shaft 10 functions as a rotation fulcrum when the display panel 3 is opened and closed with respect to the device main body 2, and is rotatably supported by the shaft support portions 2a and 2a of the device main body 2 in the axial direction. There is. Therefore, the display panel 3 is opened and closed between the closed position P1 and the open position P2 with respect to the apparatus main body 2 with the first hinge shaft 10 as a fulcrum (see FIG. 2).

The closed position P1 of the display panel 3 is a position accommodated in the accommodating portion 8, and the open position P2 of the display panel 3 is a position opened about 180 degrees with respect to the closed position P1 with the first hinge shaft 10 as a fulcrum. be. Each position in the state where the display panel 3 is opened from the closed position P1 with respect to the device main body 2 with the first hinge shaft 10 as the fulcrum is when the display panel 3 is rotated with the second hinge shaft 11 as the fulcrum. It is regarded as the reference position of.

Therefore, the reference position is each position where the display panel 3 is released from the closed position P1 with the first hinge shaft 10 as the fulcrum, for example, the position where the display panel 3 is opened 90 degrees or 120 degrees with respect to the apparatus main body 2. Each position such as the designated position is also included, and the above-mentioned open position P2 is also regarded as one of the reference positions. Further, regardless of the orientation of the display unit 12, if the display panel 3 is at each position opened from the closed position P1 with the first hinge shaft 10 as a fulcrum, for example, the display unit 12 faces forward. It is a position that includes both the position where it was and the position where it faces backward.

The second hinge shaft 11 is provided between one side portion of the panel body 9 and the central portion in the axial direction of the first hinge shaft 10, and the axial direction is relative to the axial direction of the first hinge shaft 10. It is orthogonal and is oriented in a direction different from the axial direction of the first hinge axis 10 (see FIG. 1). The second hinge shaft 11 functions as a rotation fulcrum when the display panel 3 is rotated in a state of being open to the device main body 2, and is rotatably supported by the first hinge shaft 10 in the axial direction. Has been done. Therefore, the display panel 3 is rotated around the device main body 2 between the first rotation position Q1 and the second rotation position Q2 with the second hinge shaft 11 as a fulcrum (see FIG. 3).

The first rotation position Q1 of the display panel 3 is, for example, when the upper end portion is rotated forward in the direction of tilting forward with respect to the reference position in the state where the display unit 12 faces backward at the open position P2. The second rotation position Q2 of the display panel 3 is the position of the rotation end of the above, and the second rotation position Q2 is rotated backward to R2 in the direction in which the upper end portion tilts backward with respect to the reference position in the state where the display unit 12 faces backward. It is the position of the rotating end at the time. The display panel 3 is rotatable about 180 degrees in the forward rotation R1 and is rotatable 90 degrees in the rearward rotation R2 with respect to the device main body 2, and has a second hinge shaft 11 as a fulcrum. The total rotation angle is, for example, 270 degrees.

Therefore, in the display panel 3, the reference position when the display unit 12 faces forward coincides with the first rotation position Q1, and when the first rotation position Q1 is set to 0 degrees, the display panel 3 reaches the second rotation position Q2. It is rotatable within a range of 270 degrees, and the position where the display unit 12 faces directly downward coincides with the second rotation position Q2.

The image pickup device 1 is provided with a first magnetic detection unit 51, a second magnetic detection unit 52, and a third magnetic detection unit 53 (see FIG. 4). Each of these magnetic detection units includes a first sensor 61, a second sensor 62, a third sensor 63, a fourth sensor 64, a first magnet 71, a second magnet 72, and a third magnet 73. It is provided. The first magnetic detection unit 51, the second magnetic detection unit 52, and the third magnetic detection unit 53 are, for example, MR sensors using a magnetoresistive effect element. However, the first magnetic detection unit 51, the second magnetic detection unit 52, and the third magnetic detection unit 53 may be Hall sensors using Hall elements.

The first magnetic detection unit 51 is composed of a first sensor 61, a fourth sensor 64, and a first magnet 71, and the second magnetic detection unit 52 is composed of a second sensor 62 and a second magnet 72. The third magnetic detection unit 53 is composed of a third sensor 63 and a third magnet 73. Therefore, the first magnet 71 is also used for the first sensor 61 and the fourth sensor 64.

In the image pickup apparatus 1, each of the above-mentioned sensors is arranged inside the apparatus main body 2 or one of the insides of the display panel 3, and each of the above-mentioned magnets is arranged inside the apparatus main body 2 or the other of the insides of the display panel 3. Is located in. In the image pickup apparatus 1, for example, the first sensor 61, the second sensor 62, the third sensor 63, and the fourth sensor 64 are arranged inside the apparatus main body 2, and the first magnet 71 and the second sensor 64 are arranged. A magnet 72 and a third magnet 73 are arranged inside the display panel 3.

The first sensor 61 and the fourth sensor 64 are located on the extension lines S, S of the central shaft 10a of the first hinge shaft 10 on the opposite side of the second hinge shaft 11, and the shaft support portion 2a, Inside 2a, they are arranged in a line-symmetrical state with respect to the second hinge axis 11. The first magnet 71 is arranged inside at the end of the panel body 9 on the first hinge shaft 10 side, and the display panel 3 is in the closed position P1 and the display unit 12 faces backward. It is located right next to it. Therefore, the first magnet 71 is positioned right beside the fourth sensor 64 when the display panel 3 is at the closed position P1 and the display unit 12 faces forward.

The second sensor 62 is arranged inside the apparatus main body 2 on the front side of the first hinge shaft 10. The second magnet 72 is arranged inside the first hinge shaft 10.

The third sensor 63 is arranged at a position immediately below the viewfinder 6 inside the upper end portion of the apparatus main body 2. The third magnet 73 is arranged at a substantially central portion in the left-right direction of the panel main body 9, and is located at the lower end portion of the panel main body 9 in a state where the display panel 3 is at the closed position P1 and the display portion 12 faces rearward. Therefore, the third magnet 73 is located at the upper end of the panel main body 9 when the display panel 3 is at the closed position P1 and the display unit 12 faces forward.

In the image pickup apparatus 1, it is possible to take pictures in various shooting states (see FIGS. 5 to 11).

When the display panel 3 is in the closed position P1 and the display unit 12 faces backward, normal shooting (closed position normal shooting) for shooting a subject other than itself is possible (see FIG. 5).

The display panel 3 is opened with respect to the closed position normal shooting state, and for example, by opening the display panel 3 by about 180 degrees to the open position P2, so-called self-shooting (self-shooting) shooting with the subject as a subject becomes possible (selfie shooting). See FIG. 6).

With the display panel 3 open, the display unit 12 is rotated to a position facing upward, which enables so-called low-angle shooting in which the subject is photographed from below (see FIG. 7). However, low-angle shooting can be performed even when the display unit 12 faces diagonally upward.

When the display panel 3 is in the open position P2 and the display unit 12 faces backward, normal shooting (open position normal shooting) for shooting a subject other than itself is possible (see FIG. 8).

With the display panel 3 open, the display unit 12 is rotated to a position facing downward, which enables so-called high-angle shooting in which the subject is shot from above (see FIG. 9). However, high-angle shooting can be performed even when the display unit 12 faces diagonally downward.

When the display panel 3 is opened about 90 degrees from the closed position P1 and the display unit 12 faces sideways (left or right), normal shooting (horizontal normal shooting) for shooting a subject other than itself is enabled. (See FIG. 10). However, the sideways normal shooting can be performed even when the display unit 12 faces diagonally to the side.

When the display panel 3 is in the closed position P1 and the display unit 12 faces forward, the display unit 12 of the display panel 3 cannot be visually recognized for shooting, but the viewfinder 6 can be used for shooting. It is possible, and normal shooting (limited normal shooting) limited to the viewfinder 6 is possible (see FIG. 11). In limited normal shooting, the display unit 12 is placed facing the rear surface of the device main body 2 and the display unit 12 is not exposed to the outside. Therefore, the display unit 12 is protected to prevent scratches on the display unit 12. Can be done.

In the first magnetic detection unit 51 described above, the rotational state of the display panel 3 with respect to the device main body 2 is detected by the operation of the first sensor 61 according to the positional relationship with the first magnet 71 that generates magnetic flux. The rotation state of the display panel 3 with respect to the device main body 2 is detected by the operation of the fourth sensor 64 according to the positional relationship with the first magnet 71 that generates magnetic flux. Therefore, the first magnetic detection unit 51 functions as a rotation magnetic detection unit that detects the rotation state of the display panel 3 with respect to the device body 2, and the rotation state of the display panel 3 with respect to the device body 2 by the rotation magnetic detection unit. Is detected as a rotation detection result.

Specifically, the vertical inversion of the image displayed on the display unit 12 is controlled according to the rotation detection result by the first sensor 61, and when the detection state of the first sensor 61 is turned ON, the image is moved up and down. It is not inverted, and when the detection state of the first sensor 61 is OFF, the image is controlled to be inverted upside down. Further, according to the rotation detection result by the fourth sensor 64, the control regarding switching between the usable mode and the unusable mode of the eyepiece sensor 7 is performed together with the detection result by the other sensor.

On the other hand, in the second magnetic detection unit 52, the open / closed state of the display panel 3 with respect to the device main body 2 is detected by the operation of the second sensor 62 according to the positional relationship with the second magnet 72 that generates magnetic flux. .. Therefore, the second magnetic detection unit 52 functions as an opening / closing magnetic detection unit that detects the opening / closing state of the display panel 3 with respect to the device main body 2, and the opening / closing state of the display panel 3 with respect to the device main body 2 is opened / closed by the opening / closing magnetic detection unit. It is detected as a detection result.

Specifically, the left-right inversion of the image displayed on the display unit 12 is controlled according to the open / close detection result by the second sensor 62, and the image is left-right inverted when the detection state of the second sensor 62 is turned ON. When the detection state of the second sensor 62 is OFF, the image is controlled not to be flipped horizontally.

Further, in the third magnetic detection unit 53, the open / closed state of the display panel 3 with respect to the device main body 2 is detected by the operation of the third sensor 63 according to the positional relationship with the third magnet 73 that generates magnetic flux. .. Therefore, the third magnetic detection unit 53 functions as an opening / closing magnetic detection unit that detects the opening / closing state of the display panel 3 with respect to the device main body 2, and the opening / closing state of the display panel 3 with respect to the device main body 2 is opened / closed by the opening / closing magnetic detection unit. It is detected as a detection result.

Specifically, the display mode and the non-display mode of the display panel 3 are switched according to the open / close detection result by the third sensor 63, and when the detection state of the third sensor 63 is turned on, the display unit 12 is energized. Is stopped and the non-display mode is set, and when the detection state of the third sensor 63 is OFF, the display unit 12 is energized and the display mode is set.

<Control based on the detection result by the sensor>
Next, a specific example of control based on each detection result by the first sensor 61, the second sensor 62, the third sensor 63, and the fourth sensor 64 described above will be described (see FIGS. 12 to 14).

As described above, the upside down of the image displayed on the display unit 12 is controlled according to the rotation detection result by the first sensor 61 of the first magnetic detection unit 51 (see FIG. 12).

For example, when the reference position (first rotation position Q1) of the display panel 3 in a state where the display unit 12 faces forward is set to 0 degrees, the display panel 3 moves backward to R2 with respect to the device main body 2, for example. The detection state of the first sensor 61 is changed from ON to OFF in a state of being rotated by about 20 degrees, and the image displayed on the display unit 12 is turned upside down. Therefore, the image is upside down from the position where the display panel 3 is rotated about 20 degrees to the rearward rotation R2 to the second rotation position Q2 which is rotated about 270 degrees, and the display panel 3 is rearward. In the rotation range from the first rotation position Q1 to the position rotated about 20 degrees by the rotation R2, the detection state of the first sensor 61 is turned ON and the image is not inverted upside down.

Further, according to the rotation detection result by the fourth sensor 64 of the first magnetic detection unit 51, the control regarding the switching between the usable mode and the unusable mode of the eyepiece sensor 7 is performed together with the detection result by the other sensors.

For example, when the reference position (first rotation position Q1) of the display panel 3 in a state where the display unit 12 faces forward is set to 0 degrees, the display panel 3 moves backward to R2 with respect to the device main body 2, for example. The detection state of the fourth sensor 64 is changed from OFF to ON when the sensor 64 is rotated by about 150 degrees from 0 degrees, and the detection state of the fourth sensor 64 is changed when the sensor 64 is rotated by about 210 degrees from 0 degrees. The transition is made from ON to OFF. Therefore, between the rotation range from the position where the display panel 3 is rotated backward R2 from 0 degrees to about 150 degrees and the second rotation position Q2 where the display panel 3 is rotated from about 210 degrees to about 270 degrees. The fourth sensor 64 is turned off, and the fourth sensor 64 is turned on in the rotation range from the position where the display panel 3 is rotated by about 150 degrees to the rearward rotation R2 to the position where it is rotated by about 210 degrees. To.

On the other hand, the left-right inversion of the image displayed on the display unit 12 is controlled according to the opening / closing detection result by the second sensor 62 of the second magnetic detection unit 52 (see FIG. 13).

For example, when the closed position P1 of the display panel 3 is set to 0 degrees when the display unit 12 faces backward, the second display panel 3 is opened to the device main body 2, for example, about 135 degrees. The detection state of the sensor 62 is changed from OFF to ON, and the image displayed on the display unit 12 is inverted left and right. Therefore, the image is flipped horizontally from the position where the display panel 3 is opened by about 135 degrees to the open position P2 where the display panel 3 is opened by about 180 degrees, and the position where the display panel 3 is opened from 0 degrees to about 135 degrees. In the open / close range up to, the detection state of the second sensor 62 is turned off and the image is not flipped horizontally.

Further, for example, when the closed position P1 of the display panel 3 is set to 0 degrees when the display unit 12 faces forward, the display panel 3 is opened to the device main body 2 by, for example, about 135 degrees. The detection state of the sensor 62 of 2 is changed from OFF to ON, and the image displayed on the display unit 12 is inverted left and right. Therefore, the image is flipped horizontally from the position where the display panel 3 is opened by about 135 degrees to the open position P2 where the display panel 3 is opened by about 180 degrees, and the position where the display panel 3 is opened from 0 degrees to about 135 degrees.

<Position relationship between sensor and magnet>
The positional relationship between the sensor and the magnet will be described below (see FIGS. 15 to 18). It should be noted that FIGS. 16 to 18 conceptually show the cross-sectional shape along the line AA of FIG.

In the image pickup apparatus 1, as described above, the first sensor 61 and the fourth sensor 64 have an extension line S of the central axis 10a of the first hinge axis 10 on the opposite side of the second hinge axis 11. It is located on S (see FIGS. 15 to 17).

Since the display panel 3 is opened and closed within a range of about 180 degrees between the closed position P1 and the open position P2 with respect to the apparatus main body 2, the first sensor 61 and the fourth sensor 64 are positioned on the extension line S. As a result, the distance L between the first sensor 61 and the first magnet 71 is always substantially the same regardless of the position of the display panel 3 in the opening / closing operation, and the fourth sensor 64 and the first sensor 64 have the same distance L. The distance L from the magnet 71 is always substantially the same (see FIG. 15).

Therefore, in the opening / closing operation of the display panel 3, the detection states of the first sensor 61 and the fourth sensor 64 can always be set to the same state (ON or OFF), and the opening / closing operation of the display panel 3 is for rotation. The configuration does not affect the rotation detection result by the first magnetic detection unit 51 that functions as the magnetic detection unit, and the mode setting of the viewfinder 6 can be appropriately controlled.

Further, in the image pickup apparatus 1, as described above, the first sensor 61 and the fourth sensor 64 are arranged in a line-symmetrical state with respect to the second hinge axis 11 (see FIGS. 16 and 17). ). At this time, in a state where the display panel 3 is rotated with respect to the device main body 2 between the open position and the closed position without being rotated with the second hinge shaft 11 as a fulcrum, the first magnet 71 is with the N pole. The S poles are arranged inside the display panel 3 in a state of being arranged vertically.

Therefore, when the first sensor 61 is positioned directly above the fourth sensor 64 while the display panel 3 is in the open position, the detection direction of the magnetic flux generated in the first magnet 71 of the first sensor 61 is When the display panel 3 is rotated 180 degrees in the open position and the fourth sensor 64 is positioned directly above the first sensor 61, the fourth sensor 64 is moved upward (see FIG. 16). The detection direction of the magnetic flux generated in the first magnet 71 is set downward D (see FIG. 17).

In this way, the first sensor 61 and the fourth sensor 64 are brought into a state of line symmetry with respect to the second hinge axis 11, and the display panel 3 is rotated 180 degrees before and after the first sensor 61. By making the detection direction of the magnetic flux of the fourth sensor 64 symmetrical with respect to the second hinge axis 11, the first sensor 61 and the fourth sensor use one first magnet 71 at the open position. The proper detection state of each of 64 is ensured. As a result, it is possible to secure a detection state with high accuracy while reducing the number of parts.

Further, in the image pickup apparatus 1, the second sensor 62 and the second magnet 72 are positioned close to the second hinge shaft 11, and the first magnet 71 is located at the end inside the display panel 3. The distance from the hinge shaft 11 of 2 is increased (see FIG. 18). Note that FIG. 18 shows the moving range of the second magnet 72 when the display panel 3 is opened and closed by a virtual line (dashed-dashed line).

The display panel 3 is rotated within a range of 270 degrees with respect to the apparatus main body 2, but since the first magnet 71 is located far away from the second hinge shaft 11, the second sensor is rotated within the rotation range. It is also located away from the 62 and the second magnet 72. Further, the detection direction of the magnetic flux generated in the first magnet 71 of the first sensor 61 and the fourth sensor 64 is the radial direction centered on the second hinge shaft 11, whereas the second magnet 72 has a detection direction. The detection direction of the generated magnetic flux is set to the axial direction of the second hinge shaft 11.

Therefore, it is possible to prevent magnetic interference from the first magnet 71 with respect to the second magnet 72 and erroneous detection of the first sensor 61 and the fourth sensor 64 due to the presence of the first magnet 71.

<Summary>
As described above, in the image pickup apparatus 1, one magnet (first magnet 71) is used for two sensors (first sensor 61 and fourth sensor 64), and two sensors are used. And one magnet constitute a magnetic detection unit for rotation, the magnetic detection unit for rotation detects the rotation state of the display panel 3 with respect to the device main body 2 as a rotation detection result, and the display panel 3 is determined from a reference position. When the viewfinder 6 is rotated to the rotation position, the viewfinder 6 cannot be switched from the unusable mode to the usable mode at least based on the rotation detection result.

Therefore, based on the rotation detection result by the rotation magnetic detection unit composed of the two sensors and one magnet that is also used in the state where the display panel 3 is rotated from the reference position to the predetermined rotation position. The state in which the display unit 12 is set to the display mode is maintained regardless of the shooting state. As a result, it is possible to appropriately switch between the mode of the viewfinder 6 and the mode of the display unit 12 according to the shooting state without causing an increase in manufacturing cost. Further, since the magnetic detection unit for rotation is composed of two sensors and one magnet, the number of devices for detection is reduced, and the space for arranging the devices can be reduced accordingly. It is also possible to reduce the size of the image pickup apparatus 1.

Further, the display panel 3 is made rotatable in the direction opposite to the reference position, and the viewfinder 6 is released from the unusable mode in each of the rotation directions of one rotation direction and the other rotation direction of the display panel 3. Switching to the available mode is disabled.

Therefore, in any case where the display panel 3 is rotated in the opposite direction to the reference position, it is impossible to switch the viewfinder 6 from the unusable mode to the usable mode, so that the display unit can be displayed in different shooting states. It becomes possible to confirm the image displayed on the 12 and perform shooting, and the degree of freedom in the shooting mode is increased, so that the usability of the image pickup apparatus 1 can be further improved.

Further, of the two sensors, the first sensor 61 and the fourth sensor 64, the first sensor 61 is provided as a sensor for controlling the inversion of the image displayed on the display unit 12.

Therefore, since the sensor for controlling the inversion of the image functions as a sensor for switching the mode of the viewfinder 6, the sensor for controlling the inversion of the image and the mode of the viewfinder 6 are switched. It is not necessary to separately provide a sensor, and it is possible to improve the usability of the image pickup apparatus 1 after reducing the number of parts.

Furthermore, an open / close magnetic detection unit that detects the open / closed state of the display panel 3 with respect to the device main body 2 is provided as an open / close detection result, and can be used from the unusable mode of the viewfinder 6 based on the rotation detection result and the open / close detection result. Switching to the mode is disabled.

Therefore, since the mode setting of the viewfinder 6 is controlled according to the rotational state of the display panel 3 with respect to the device main body 2 and the open / closed state of the display panel 3 with respect to the device main body 2, control of the mode setting of the viewfinder 6 is performed. Can be performed finely according to the shooting state to further improve the usability of the image pickup apparatus 1.

Further, the second sensor 62 of the magnetic detection unit for opening and closing is provided as a sensor for performing image inversion control.

Therefore, since the sensor for controlling the inversion of the image functions as a sensor for switching the mode of the viewfinder 6, the sensor for controlling the inversion of the image and the mode of the viewfinder 6 are switched. It is not necessary to separately provide a sensor, and it is possible to improve the usability of the image pickup apparatus 1 after reducing the number of parts.

Further, an eyepiece sensor 7 for switching between the usable mode and the unusable mode of the viewfinder 6 is provided, and the eyepiece sensor 7 detects when the display panel 3 is rotated from the reference position to a predetermined rotation position. The operation is disabled.

Therefore, since the detection operation of the eyepiece sensor 7 is disabled, the viewfinder 6 cannot be switched from the unusable mode to the usable mode. Therefore, the mode setting of the viewfinder 6 can be controlled by a simple configuration. Can be done properly.
