As shown in FIGS. 4 and 5, a control board 63 (power supply means) which is a rigid board parallel to the stage plate 40 is provided on the left side of the front yoke 21, the rear yoke 22, and the stage plate 40. The control board 63 is fixed to the inner surface of the camera body 12 by a fixing screw (not shown) so as to be positioned on substantially the same plane as the rear yoke 22 and the stage plate 40.
As shown in the drawing, the left end portions of the imaging element FPC 48 and the coil energization FPC 53 are connected to the rear surface of the control board 63 in a fixed state. The control board 63 includes a Y drive driver DYA for controlling the Y direction drive coil CYA (flowing current), a Y drive driver DYB for controlling the Y direction drive coil CYB, and an X direction drive. One X drive driver DX (first driver) for simultaneously controlling the coils CXA and CXB is provided (see FIG. 9). As shown in FIG. 9A, the Y drive driver DYA (second driver) and the Y direction drive coil CYA are connected in series to each other on the electric circuit formed on the coil energizing FPC 53 and the control board 63. The Y driving driver DYB (second driver) and the Y direction driving coil CYB are also connected in series with each other on the electric circuit. On the other hand, as shown in FIG. 9B, the X-direction drive coil CXB and the electrical resistor 56 and the X-direction drive coil CXA are in parallel to one X drive driver DX on the electrical circuit. Connected with.
Further, a battery (not shown) and a gyro sensor GS (see FIG. 1) provided inside the camera body 12 are connected to the control board 63.
The components 21 to 63 described above are components of the image shake correction apparatus 20.

In the image shake correction apparatus 20 having the above-described configuration, the control board 63 causes an image shake correction operation by causing a current to flow to the X direction drive coils CXA and CXB and the Y direction drive coils CYA and CYB via the coil energization FPC 53. I do.
For example, when image shake in the X direction occurs in the camera 10, when the image shake correction switch SW (see FIG. 1) provided in the camera body 12 is pressed, the gyro sensor GS built in the camera 10 causes the angular velocity of the camera body 12 to move. Is detected. Then, the X drive driver DX of the control board 63 calculates the movement distance (image shake amount) of the camera body 12 in the X direction based on this angular velocity information, and the same for the X direction drive coil CXA and the electric resistance 56. A large current is applied. Since the current flowing through the electric resistance 56 is reduced in current value by the electric resistance 56 and then flows into the X direction driving coil CXB, the current flowing through the X direction driving coil CXB is smaller than the current flowing through the X direction driving coil CXA. As a result, the driving force in the FX1 (FX2) direction generated by the X direction driving coil CXB is smaller than the driving force in the FX1 (FX2) direction generated by the X direction driving coil CXA. The resistance value of the electric resistance 56 is determined by the distance in the Y direction side 44 Y (LA, see FIG. 6) from the reference straight line SLX to the driving force center position of the X direction driving coil CXA and the X direction driving coil CXB from the reference straight line SLX. The difference between the Y direction side edge 44 to the driving force center position in the Y direction (LB; see FIG. 6) is the current value (IA) flowing in the X direction driving coil CXA and the current flowing in the X direction driving coil CXB. The size is set (so as to be an appropriate value) so as to be offset by the difference between the values (IB). That is, the resistance value of the electrical resistor 56 is set so that the relationship LA: LB = IB: IA is established. Therefore, the X-direction driving coil is determined by the distance in the Y-direction side 44Y direction from the reference straight line SLX extending in the direction parallel to the X-direction side 44X through the center of gravity G of the integrated movable body 62 to the X-direction driving coil CXA. Although the distance in the Y direction side 44Y direction to CXB is long (the X direction driving coil CXA and the X direction driving coil CXB are not symmetrical with respect to the reference straight line SLX), the integrated movable body 62 (stage plate 40) Can be linearly moved in the FX1 and FX2 directions. Accordingly, if the image pickup device 44 (integral movable body 62) is linearly moved in the FX1 direction or the FX2 direction by the same distance as the image blur amount with respect to the camera body 12 in the direction opposite to the image blur direction (integral movable body). 62 is detected by the X hall element HX), and the image blur of the image sensor 44 is corrected.

  On the other hand, when the image shake correction switch SW is pushed in when image shake in the Y direction occurs in the camera 10, the gyro sensor GS detects the angular velocity of the camera body 12, and drives the Y drive driver DYA and Y drive on the control board 63. Based on this angular velocity information, the driver DYB calculates the movement distance (image shake amount) of the camera body 12 in the Y direction, and further supplies the same current to the Y direction driving coil CYA and the Y direction driving coil CYB. Therefore, the Y-direction driving coil CYA and the Y-direction driving coil CYB generate the driving force in the FY1 (FY2) direction having the same magnitude. As described above, the distance in the X-direction side 44X direction from the reference straight line SLY extending in the direction parallel to the Y-direction side 44Y through the center of gravity G of the integrated movable body 62 and the Y-direction drive Since the X direction side 44X direction to the coil CYB is the same, if the same current flows through the Y direction driving coil CYA and the Y direction driving coil CYB, the integrated movable body 62 (stage plate 40) is FY1. , FY2 (Y-direction side edge 44Y) is linearly moved in a direction parallel to the direction. Therefore, if the image pickup device 44 (integral movable body 62) is linearly moved in the FY1 direction or the FY2 direction by the same distance as the image blur amount in the direction opposite to the image blur direction with respect to the camera body 12 (integral movable body 62). The Y-direction slide amount is detected by the Y hall element HY), and the image blur of the image sensor 44 is corrected.

  Further, when the image stabilization switch SW is pressed when the image shake in the rotation direction occurs in the camera 10, the gyro sensor GS detects the angular velocity of the camera body 12, and the X drive driver DX and the Y drive driver of the control board 63 are detected. DYA and DYB calculate the movement distance (image shake amount) of the camera body 12 in the X direction and the Y direction based on the angular velocity information, and generate the same current for the X direction driving coil CXA and the electric resistance 56. While flowing, currents of different magnitudes are passed through the Y-direction driving coil CYA and the Y-direction driving coil CYB. Then, since the Y-direction driving coil CYA and the Y-direction driving coil CYB generate different driving forces, the X-direction driving coils CXA and CXB drive the FX1 (FX2) direction and the Y-direction driving coil CYA. And the Y direction driving coil CYB, the resultant force of the driving force in the FY1 (FY2) direction causes the image sensor 44 (integral movable body 62) to rotate in the opposite direction to the image blur direction by the same distance as this image blur amount. The image blur (rotational shake) of the element 44 is corrected.

  When a shutter button (not shown) provided on the camera body 12 is pressed with the image blur corrected, an image pickup signal (electric signal) is sent from the control board 63 to the image pickup device 44 via the image pickup device FPC 48. The image sensor 44 performs an imaging operation. Furthermore, image data (electrical signals) sent from the image sensor 44 to the control board 63 via the image sensor FPC 48 are displayed on a display (not shown) provided on the back surface of the camera body 12.

Furthermore, in this embodiment, the control board 63 is not disposed immediately after the rear yoke 22 but is disposed on the left side of the front yoke 21 and the rear yoke 22. Therefore, since the image shake correction apparatus 20 can be thinned in the Z direction, the camera body 12 can be thinned in the Z direction.
When the stage plate 40 (integral movable body 62) slides in the X direction with respect to the front yoke 21 and the rear yoke 22, the deformation portion 49 of the imaging element FPC 48 and the deformation portion 54 of the coil energization FPC 53 are left and right. Since it expands and contracts (deforms) in the direction, the sliding operation of the stage plate 40 (integrated movable body 62) is not hindered by the imaging element FPC 48 and the coil energization FPC 53. Therefore, the stage plate 40 (integrated movable body 62) can smoothly slide in the X direction. Similarly, when the stage plate 40 (integral movable body 62) slides in the Y direction with respect to the front yoke 21 and the rear yoke 22 and rotates relative to the front yoke 21 and the rear yoke 22, the deforming portion 49 and the deforming portion 54 have their right side pieces 49a. , 54a and the left side pieces 49b, 54b are deformed while being non-parallel, so that the stage plate 40 (integral movable body 62) can smoothly slide in the Y direction and the rotational direction.
Further, since the front protective piece 61 of the FPC cover member 58 is located immediately before the deformable portion 49 and the deformable portion 54 and the right protective piece 60 is located on the right side of the right pieces 49a and 54a, the camera body 12 is moved in the Z direction. Even if a component other than the image shake correction device 20 provided inside the camera body 12 (for example, a shutter not shown) is positioned in front of the FPC cover member 58 when the thickness is reduced, the deforming portion 49 (imaging element FPC 48) and the deformable portion 54 (coil energization FPC 53) do not come into contact with the component. Further, the right side pieces 49 a and 54 a of the deforming portion 49 and the deforming portion 54 do not contact the left end portions of the front yoke 21 and the rear yoke 22. Therefore, even when the camera body 12 is thinned in the Z direction, the wear and damage of the imaging element FPC 48 and the coil energization FPC 53 can be prevented.
Further, the portion located on the right side of the deformed portion 49 of the image sensor FPC 48 is located in the flex escape recess 22a. Therefore, even when the distance between the front yoke 21 and the rear yoke 22 in the Z direction is shortened in order to reduce the thickness of the camera body 12 in the Z direction, the portion located on the right side of the deformed portion 49 of the imaging element FPC 48 is the rear yoke. Thus, the wear and damage of the image sensor FPC 48 can be prevented.

As mentioned above, although this invention was demonstrated using the said embodiment, this invention is not limited to this embodiment, It can implement, giving various changes.
For example, the driving force center of the X-direction driving coil CXB is calculated from the distance in the Y-direction side 44Y from the reference straight line SLX to the driving force center position of the X-direction driving coil CXA as in the first modification shown in FIG. The X-direction drive coil CXB is disposed on the left side of the image sensor 44 (fixed to the stage plate 40) while increasing the distance in the Y-direction side 44 to the position, and the electric resistance in the same manner as in FIG. 9B. 56 may be arranged on an electric circuit formed on the coil energization FPC 53 and the control board 63. In the case of this modification as well, the same operational effects as in the above embodiment can be exhibited.

  The second modification shown in FIG. 11 is a Y-direction side edge 44Y on the upper side of the X-direction drive coil CXB arranged on the left side of the image sensor 44 and on the lower side of the X-direction drive coil CXA arranged on the right side of the image sensor 44. It is a modification in which the direction position is partially matched. Also in this case, the Y-direction side edge 44Y direction from the reference straight line SLX to the Y-direction side edge 44Y direction distance from the driving force center position of the X-direction driving coil CXA to the driving force center position of the X-direction driving coil CXB. The distance is increased, and the electric resistor 56 is arranged on the electric circuit formed on the coil energizing FPC 53 and the control board 63 in the same manner as in FIG. 9B. Therefore, also in this case, it is possible to exert the same effect as the above embodiment.

  Further, the X magnet MX and the Y magnet MY may be fixed to the rear yoke 22 side instead of the front yoke 21 side.

  Further, the electric resistance 56 is omitted, and the strength (magnetic flux density) of the magnetic field generated by the X magnet MX facing the X direction driving coil CXB on the front yoke 21 and the stage plate 40 is determined as the X direction driving coil CXA. Magnetic flux reduction means for reducing the magnetic flux compared with the X magnet MX facing (for example, a covering material covering a part of the X magnet MX facing the X direction driving coil CXB, or the X facing the X direction driving coil CXB) A driving force reducing means such as a permanent magnet for reducing the magnetic flux density of the magnetic field of the X magnet MX by applying a magnetic force to the magnetic field of the magnet for MX may be provided. In this case, although the same current flows in the X direction driving coil CXA and the X direction driving coil CXB, the X direction driving coil CXB is located in a magnetic field having a smaller magnetic flux density than the X direction driving coil CXA. As a result, the driving force generated by the X-direction driving coil CXB is smaller than the driving force generated by the X-direction driving coil CXA. Therefore, the same effect as the above embodiment can be obtained.

  Further, the distance in the Y-direction side 44Y direction from the reference straight line SLX to the driving force center position of the X-direction driving coil CXA is shorter than the distance in the Y-direction side edge 44Y direction from the reference straight line SLX to the driving force center position of the X-direction driving coil CXA. Then, by using the electric resistance 56, the magnitude of the current flowing through the X direction driving coil CXA is made smaller than that of the X direction driving coil CXB, or the magnetic flux reducing means is used to drive the X direction. The magnetic flux density of the magnetic field generated by the X magnet MX facing the coil CXA may be smaller than the magnetic flux density of the magnetic field generated by the X magnet MX facing the X direction driving coil CXB.

  Further, when the distance in the X direction side 44X direction from the reference straight line SLY to the Y direction drive coil CYA and the X direction side edge 44X direction from the reference straight line SLY to the Y direction drive coil CYB are different from each other, the Y drive Image blurring in the Y direction is corrected by making the magnitude of the current flowing from the driver DYA to the Y-direction driving coil CYA and the magnitude of the current flowing from the Y driving driver DYB to the Y-direction driving coil CYB differ from each other. For example, when the distance from the reference straight line SLY to the Y-direction drive coil CYA is longer than the distance from the Y-direction drive coil CYB, the magnitude of the current flowing through the Y-direction drive coil CYB is set in the Y-direction drive coil CYA. The image blur in the Y direction is corrected by making it smaller than the magnitude of the flowing current (the integral movable body 62 is linearly moved in the FY1 direction or the FY2 direction).

Further, the functions of the X direction driving coils CXA and CXB and the Y direction driving coils CYA and CYB may be interchanged. That is, the X direction driving coil CXA and the X direction driving coil CXB can generate different driving forces, and the Y direction driving coils CYA and CYB always have the same driving force. As shown, an electric resistance 56 connected to one of the Y direction driving coil CYA and the Y direction driving coil CYB is provided on one side of the Y direction driving coil CYB and the Y direction driving coil CYB. Or a magnetic flux reducing means for reducing the magnetic flux density of one magnetic field of the Y magnet MY facing the Y direction driving coil CY and the Y magnet MY facing the Y direction driving coil CYB compared to the other. Also good.
Of the X-direction driving coil and the Y-direction driving coil, the one that performs rotation control may be constituted by three or more coils.

12, instead of the FPC cover member 58, the mounting piece 59, the right protective piece 60, the front protective piece 61, and the left edge portion of the front protective piece 61 extend rearward. The FPC cover member 65 (attachment piece 59) having a structure including the left protection piece 66 may be fixed to the stage plate 40. In this way, not only the front and right sides of the deformed portion 49 of the imaging element FPC 48 and the deformed portion 54 of the coil energizing FPC 53 but also the left side can be protected by the left protection piece 66.
Further, as in the fourth modification shown in FIG. 13, an FPC cover member 67 having a structure corresponding only to the front protective piece 61 is employed, and the right end portion of the FPC cover member 67 is fixed to the stage plate 40. May be.

Moreover, you may implement in the shape of the 5th modification shown in FIG.
The rear yoke 70 of this modification has a rectangular frame shape composed of two sides extending in the X direction and two sides extending in the Y direction, and a central through hole 71 is formed at the center thereof. Further, a lateral through hole 72 is formed in the left side portion of the rear yoke 70 as a long hole that is not in communication with the central through hole 71.
As shown in the drawing, the right side piece 49a of the imaging element FPC 48 and the right side piece 54a of the coil energizing FPC 53 are inserted into the side through holes 72 from the rear of the rear yoke 70 (on the left side of the rear yoke 70). The cover member 58 (65, 67) has a fixed mounting piece 59, but the cover member is not shown).
In this modified example, the rear yoke 70 is connected to the left ends of two upper and lower pieces extending in the X direction by the left side extending in the Y direction, and therefore has higher mechanical strength than the rear yoke 22.

Furthermore, after the stage device is provided in the lens barrel 11, a correction lens (blur correction unit) may be fixed to the stage plate 40 instead of the image sensor 44 (at the same position as the image sensor 44).
The correction lens positioned in the photographing optical path is a lens that constitutes an imaging optical system together with the lens groups L1 to L3. When the stage plate 40 slides, the correction lens moves in a plane orthogonal to the lens optical axis OA, so that the image blur is corrected by the correction lens.

  Further, the lead of the image sensor 44 may be soldered to a rigid board (circuit board) parallel to the stage board 40 disposed immediately after the stage board 40, and the right end of the image sensor FPC 48 may be connected to the rigid board. .

  In addition, two X magnets MX (driving member) (first driving member) are arranged side by side in the Y direction side 44Y direction and fixed to the stage plate 40, and two Y magnets MY (driving member) (second driving member). ) Are arranged and fixed in the X direction side 44X direction, and the X direction driving coils CXA and CXB are fixed in the Y direction side side 44Y direction and fixed to the front yoke 21 (or the rear yoke 22). The coils CYA and CYB may be arranged side by side in the X direction side 44X direction and fixed (in this case, the two X magnets MX have a long distance in the X direction side side 44X direction from the reference straight line SLY, Driving force reducing means for reducing the magnetic flux density of the magnetic field of the X magnet MX is provided).

  Further, in the above-described embodiment, the present invention is applied to the image shake correction apparatus 20 in which the stage plate 40 can rotate. However, the present invention is applied to a known image shake correction apparatus in which the stage plate 40 moves linearly only in the X direction and the Y direction. Alternatively, it can be applied to a stage apparatus (an apparatus in which a specific member can linearly move or rotate in the X direction or the Y direction) having a different use from the image shake correction apparatus.
