The second flexible printed wiring board and the third flexible printed wiring board are bent in a state in which the thickness direction is in the front-rear direction and the respective parts face each other in the optical axis direction, and a part thereof is led out rearward from the opening 13a of the base plate 9. It is connected to the drive circuit board (power supply board). The second flexible printed wiring board and the third flexible printed wiring board transfer signals between, for example, the circuit board 23 and the drive circuit board.

Connection members 39 and 39 are attached to the fixed side heat transfer plates 12 and 12 attached to the base plate 9 in the fixed body 7 and the movable side heat transfer plates 18 and 18 attached to the circuit board 23 in the movable body 8, respectively. (See FIGS. 4 and 5). The number of connecting members 39 provided in the image pickup apparatus 1 is arbitrary, and the number of the fixed side heat transfer plate 12 and the movable side heat transfer plate 18 is changed according to the number of the connecting members 39.

The connecting member 39 is, for example, a heat transfer sheet formed of a plurality of sheet members 40, 40, ... Made of graphite (see FIG. 11). In the connecting member 39, the seat members 40, 40, ... Are overlapped in the thickness direction and bent into a predetermined shape, for example, a shape in which two sigma (Σ) shapes in opposite directions are connected on the left and right, and the seat member 40, 40, ... Is formed by joining both ends in the longitudinal direction to form an annular shape that penetrates back and forth.

The connecting member 39 is a pair of deformed portions 43, 43 located between the fixed side mounting portion 41 and the movable side mounting portion 42, which are vertically opposed to each other, and the fixed side mounting portion 41 and the movable side mounting portion 42. It is composed of and.

The fixed side mounting portion 41 and the movable side mounting portion 42 face in the vertical direction, the fixed side mounting portion 41 is joined to the mounting plate portion 12b of the fixed side heat transfer plate 12, and the movable side mounting portion 42 is the movable side heat transfer plate 18. It is joined to the mounting plate portion 18b of.

The deformed portions 43, 43 are positioned apart from each other to the left and right, and the upper and lower ends are continuous with the left and right ends of the fixed side mounting portion 41 and the left and right end portions of the movable side mounting portion 42, respectively. The deformed portion 43 is provided with a half portion on the fixed side mounting portion 41 side as a first portion 43a, a half portion on the movable side mounting portion 42 side as a second portion 43b, and a first portion 43a on the fixed side mounting. It is bent at an acute angle with respect to the portion 41, and the second portion 43b is bent at an acute angle with respect to the movable side mounting portion 42. In the deformed portion 43, the continuous portion 43c of the first portion 43a and the second portion 43b bends the first portion 43a with respect to the fixed side mounting portion 41 and the second portion 43b with respect to the movable side mounting portion 42. It is bent in the opposite direction. Therefore, the deformed portions 43, 43 are formed in a V shape that opens outward in the left-right direction, and the distance between the continuous portions 43c, 43c is shorter than the length of the fixed side mounting portion 41 and the movable side mounting portion 42 in the left-right direction. ing.

As described above, in the connecting member 39, since the deformed portions 43 and 43 are not joined to any of the fixed body 7 and the movable body 8, the movable body 8 is orthogonal to the fixed body 7 in the optical axis direction. The deformable portions 43, 43 are made deformable when moved to.

In the connecting member 39, at least the deformed portions 43, 43 are stacked in a state where the plurality of sheet members 40, 40, ... Are not joined. The fixed-side mounting portion 41 and the movable-side mounting portion 42 are stacked with a plurality of seat members 40, 40, ... Joined or not joined.

As described above, each part of the connecting members 39, 39 is joined to the fixed side heat transfer plates 12 and 12 attached to the base plate 9 and the movable side heat transfer plates 18 and 18 attached to the circuit board 23. The fixed body 7 and the movable body 8 are connected by the connecting members 39, 39.

One end of a heat conductive sheet (not shown) formed of graphite or the like is attached to the attached plate portion 12a of the fixed side heat transfer plate 12 from the rear. The other end of the heat conductive sheet is attached to, for example, the inner surface of the outer casing 3.

<Operation in the image pickup device>
In the image pickup device 1 configured as described above, the image pickup element 22a is in the driving state when the power is turned on, such as during shooting, and heat is generated from the movable body 8, particularly the image pickup element 22a and the circuit board 23. appear. The heat generated in the movable body 8 is transferred from the movable side heat transfer plate 18 to the fixed side heat transfer plate 12 via the connecting member 39. The heat transferred to the fixed-side heat transfer plate 12 is transferred to the outer casing 3 from the heat conductive sheet attached to the attached plate portion 12a of the fixed-side heat transfer plate 12, and is discharged to the outside from the outer casing 3.

Therefore, the temperature rise of the movable body 8, particularly the image pickup element 22a and the circuit board 23 is suppressed, and a good driving state of the image pickup element 22a, the circuit board 23, and the like is ensured.

During the above-mentioned shooting or the like, the movable body 8 is moved in the direction orthogonal to the optical axis direction with respect to the fixed body 7, so that the blur correction operation is performed. In the blur correction operation, as the movable body 8 moves with respect to the fixed body 7, the deformed portions 43, 43 of the connecting member 39, the conductive portion 33 of the first flexible printed wiring board 30, the second flexible printed wiring board, and the second The flexible printed wiring board of 3 is deformed.

At this time, the thickness direction of the connecting member 39 is set to be orthogonal to the optical axis direction, and the deformed portion 43 to be deformed does not twist. Therefore, the load generated on the connecting member 39 is small, and the connecting member 39 can be moved from the connecting member 39. The load (drive load) applied to 8 is small.

<Center holding operation>
Next, the center holding operation performed in the image pickup apparatus 1 will be described (see FIGS. 12 to 17).

The center holding operation is an operation in which the movable body 8 is moved with respect to the fixed body 7 and the movable body 8 is held at the center position where the center of the image pickup element 22a coincides with the center of the optical axis of the lens 64. In, for example, when the power is turned on and when returning from the sleep mode, the procedure is as follows.

The center holding operation is performed by first moving the movable body 8 from the initial position to the transit position by the first movement, and then moving the movable body 8 from the transit position to the center position, and the center position is the initial position. It is a position that exists between the position and the waypoint. For example, the center position is a position existing between the initial position and the transit position in the first movement direction.

In the state where the center holding operation is started, the image pickup device 1 is usually held in an upright posture by the user (see FIG. 12), and the center P of the image pickup element 22a is the center S of the lens 64 due to gravity. It is located lower (see FIG. 13). The upright state is a posture in which the image pickup device 1 is horizontally long and the power button (operation button 4) is positioned above the outer casing 3, and the user attaches the image pickup device 1 to a tripod or the like for use. It is also the attitude of.

The first movement is a movement from the initial position of the movable body 8 to a predetermined transit position, and in the upright state, the center P of the image pickup device 22a is below the center S of the lens 64 in the initial position. Position (see FIG. 13). Further, the transit position is a predetermined position on the opposite side of the initial position with the center position in between. Therefore, in the first movement, the movable body 8 is moved upward from the initial position in the direction opposite to the direction of gravity and moved to the transit position (see FIG. 14). In the state where the movable body 8 is moved to the transit position, the center P of the image pickup device 22a is positioned above the center S of the lens 64. At this time, in the first movement, the movable body 8 is moved from the initial position, for example, beyond the center position to the transit position.

When the movable body 8 is moved from the initial position to the transit position in such a first movement, the connecting member 39, the first flexible printed wiring board 30, the second flexible printed wiring board, and the third flexible printed wiring board are used. Is deformed, and the load generated on the connecting member 39 and the like is changed.

Subsequently, the movable body 8 is moved from the transit position to the center position in the second movement (see FIG. 15). In the second movement, the movable body 8 is moved downward from the transit position in the direction of gravity and is moved to the center position. By moving the movable body 8 to the center position, the center P of the image sensor 22a coincides with the center S of the lens 64, and the blur correction operation is performed in a state where the power is turned on and a state other than the sleep mode. When not, the power supply to the first coil 36 and the second coils 37, 37 is continued, and the movable body 8 is held in the center position.

The center holding operation is performed by the second movement following the first movement as described above, but the connecting member 39 has a property that the load (driving load) changes according to the moving direction of the movable body 8. , The change in the load of the connecting member 39 will be described below (see FIG. 16).

FIG. 16 is a graph showing the state of the load generated on the connecting member 39 when the first movement and the second movement of the movable body 8 are performed. In FIG. 16, the horizontal axis indicates the position of the movable side mounting portion 42 with respect to the fixed side mounting portion 41 in the connecting member 39, and the positive direction is the direction in which the movable side mounting portion 42 approaches the fixed side mounting portion 41, and the origin is It is a design reference dimension (design nominal dimension) of the fixed side mounting portion 41 and the movable side mounting portion 42. In FIG. 16, the vertical axis indicates the load generated on the connecting member 39, and the positive direction is upward.

In FIG. 16, the point A at the left end is the position where the movable side mounting portion 42 is most separated from the fixed side mounting portion 41 by gravity and corresponds to the initial position, and the point C at the right end is movable against gravity. The body 8 is moved and the movable side mounting portion 42 is the position closest to the fixed side mounting portion 41 and is a position corresponding to the transit position.

As shown in FIG. 16, the connecting member 39 is deformed by the first movement R1 moved from the initial position of the point A to the transit position of the point C through the center position of the point B, and from the transit position of the point C. It can be seen that mechanical hysteresis occurs based on the deformation caused by the second movement R2 moved to the center position of the point D, and the load at the center position of the point D is smaller than that of the center position of the point B.

As described above, since mechanical hysteresis occurs in the connecting member 39 based on the deformation due to the first movement and the deformation due to the second movement, as described above, the connection member 39 passes through the center position from the initial position in the center holding operation. By performing the first movement to the position and then the second movement from the transit position to the center position, the load on the connecting member 39 is reduced, and the power consumption when performing the center holding operation can be reduced. become.

The image pickup device 1 is provided with a detection unit such as a gyro sensor that determines the direction of gravity by detecting the posture during use, and the movable body 8 is subjected to gravity in the first movement based on the detection result of the detection unit. It may be configured to be moved in the direction opposite to the direction and moved in the direction of gravity in the second movement.

For example, when the image pickup apparatus 1 is used in a sideways (vertically) sideways posture (see FIG. 17), the detection unit detects that the posture is in a sideways state, and based on the detection result of the detection unit. The direction of gravity is determined, and the movable body 8 is moved in the direction opposite to the direction of gravity in the first movement and is moved in the direction of gravity in the second movement.

Since the direction of gravity is determined by detecting the posture during use in this way, the movable body 8 is always moved in the direction opposite to the direction of gravity during the first movement according to the discrimination result by the detection of the detection unit. The movable body 8 is moved in the direction opposite to the direction of gravity during the first movement regardless of the posture when the image pickup device 1 is used, and the power consumption used to hold the movable body 8 at the center position in any usage state. Can be reduced.

Further, in the case where the moving image shooting mode and the still image shooting mode can be set in the image pickup apparatus 1, the first movement and the second movement are performed when the moving image shooting mode is set, and the still image shooting mode is set. At the time of setting, the movable body 8 may be configured to move from the initial position to the center position without moving to the transit position.

In general, still image shooting has a high demand for momentary scene shooting, and it is desired to reduce the loss of shutter chances. On the other hand, moving image shooting is a shooting state in which continuous shooting is performed for a certain period of time. There is a higher demand for quick start of shooting than for movie shooting.

Therefore, by setting the operation state in which the first movement and the second movement are performed in the moving image shooting mode as described above, the first movement and the second movement are not performed in the still image shooting mode. It is possible to reduce the power consumption used in the moving image shooting mode and to quickly start shooting a still image.

In the image pickup apparatus 1, a plurality of predetermined transit positions are stored in a memory or the like, and among the plurality of stored transit positions, the predetermined transit position is read from the memory according to the posture at the time of use or the shooting mode. It may be configured to be issued and selected.

In such a configuration, the movable body 8 is moved to a transit position selected according to the posture or shooting mode at the time of use by the first movement, and is the largest machine according to the posture or shooting mode. By setting in advance a waypoint that causes a target hysteresis, it is possible to reduce the power consumption to the maximum for each posture or shooting mode.

<Summary>
As described above, in the image pickup apparatus 1, the driving unit for moving the movable body 8 and the second movement from the initial position to the transit position of the movable body 8 followed by the second movement from the transit position to the center position. A control unit that controls the drive unit so that the movement of the movable body 8 is performed, and a mechanical unit that is deformed with the movement of the movable body 8 with respect to the fixed body 7 and is generated based on the deformation due to the first movement and the deformation due to the second movement. It includes a connecting member 39 having hysteresis.

Therefore, in a state where mechanical hysteresis occurs in the connecting member 39, the movable body 8 is moved from the initial position to the transit position by the first movement, and is moved from the transit position to the center position by the second movement of the movable body 8. Since the center is held, the power consumption in holding the center of the movable body 8 can be reduced.

Further, in the image pickup apparatus 1, the movement direction due to the first movement is opposite to the gravity direction.

Therefore, since the movable body 8 is moved to the transit position in the direction opposite to the direction of gravity during the first movement, the load by the connecting member 39 is efficiently reduced and used to hold the movable body 8 at the center position. Power consumption can be reduced efficiently.

When the center holding operation is performed, it is most desirable that the movable body 8 is moved in the direction opposite to the direction of gravity in the first movement in order to reduce power consumption. However, in the image pickup apparatus 1, the movable body 8 is moved. The movement direction of the first movement of 8 may be moved in a direction including a component in a direction opposite to the gravity direction, for example, diagonally upward.

In this case, the movable body 8 is moved from the initial position to the transit position in the direction including the component in the direction opposite to the gravity direction during the first movement, and even if it is moved in such a direction, it is consumed by mechanical hysteresis. It is possible to reduce power consumption.

Further, in the image pickup apparatus 1, the moving direction due to the first movement coincides with the deformation direction of the connecting member 39.

Therefore, since the movable body 8 is moved to the transit position in the deformation direction of the connecting member 39 during the first movement, the load by the connecting member 39 is efficiently reduced and used to hold the movable body 8 at the center position. Power consumption can be reduced efficiently.

Furthermore, as the connecting member 39, a heat transfer sheet that transfers heat generated in the movable body 8 to the fixed body 7 is used.

Therefore, since the heat is transferred from the movable body 8 to the fixed body 7 by the connecting member 39 having the mechanical hysteresis, the movable body 8 is provided with a good heat transfer state from the movable body 8 to the fixed body 7. The power consumption used for holding to the center position can be reduced.

Although the example in which the heat transfer sheet is used as the connecting member 39 is shown above, for example, a flexible printed wiring board that is deformed with the movement of the movable body 8 may be used as the connecting member.

In this case, it is possible to reduce power consumption by utilizing the mechanical hysteresis of the flexible printed wiring board for supplying current and exchanging signals to each part of the movable body 8. It is possible to reduce the power consumption used for holding the movable body 8 at the center position without causing an increase in manufacturing cost or complication of the structure.

Further, since the first movement and the second movement are performed when the power is turned on, the first movement and the second movement are performed with the start of use of the image pickup device 1, and therefore, when the image pickup device 1 is used. It is possible to reduce the power consumption that is always used to hold the movable body 8 in the center position.

On the other hand, since the first movement and the second movement are performed at the time of returning from the sleep mode, the movable body 8 is not held at the center position in the sleep mode and the image pickup device 1 is returned to the used state. Since the first movement and the second movement are performed in accordance with the above, the power consumption used in the image pickup apparatus 1 can be efficiently reduced.

Further, according to the movement control method in which the movable body 8 is moved from the initial position to the transit position in the first movement and the movable body 8 is moved from the transit position to the center position in the second movement, the image pickup apparatus 1 described above. The same effect as that of the above can be obtained, and the power consumption in holding the center of the movable body 8 can be reduced.
