(Schematic operation of optical device for photographing)
In the photographic optical device 1 configured as described above, when a current is supplied to the lens driving coil 18, the lens moves in the optical axis direction together with the movable body 5. Further, in the photographing optical device 1, when a change in the tilt of the camera module 3 is detected by the gyroscope mounted on the substrate 22, current is supplied to the shake correction coil 38 based on the detection result of the gyroscope. Is done. When a current is supplied to the shake correction coil 38, the camera module 3 swings so that the optical axis L is inclined with the fulcrum portion 36 as the center and the left and right direction and / or the front and back direction as the axial direction. It is corrected.

  In this embodiment, the shake correction mechanism that corrects the shake by swinging the camera module 3 so that the optical axis L is inclined with respect to the support 27 by the leaf spring 28, the swing drive mechanism 29, the fulcrum portion 36, and the like. Is configured.

(Main effects of this form)
As described above, in this embodiment, the shake correction magnet 39 is directly fixed to the outer peripheral surface of the camera module 3. Therefore, in this embodiment, as compared with the conventional case, the photographing optical device 1 is reduced in size compared to the case where the shake correction magnet 39 is fixed to the yoke disposed so as to cover the outer peripheral surface of the camera module 3. It becomes possible. In particular, in this embodiment, since the movable side fixing portion 28a of the leaf spring 28 is directly fixed to the camera module 3, compared with a case where a member to which the movable side fixing portion 28a is fixed is provided separately, the photographing optical device. 1 can be further downsized.

  Further, in this embodiment, it is possible to reduce the weight of the swinging portion as compared with the case where the yoke is disposed so as to cover the outer peripheral surface of the camera module 3. In this embodiment, if the size of the photographic optical device 1 is the same as that of the conventional photographic optical device, it is possible to enlarge the shake correction magnet 39 and the shake correction coil 38 by the amount of the yoke. Therefore, the driving force of the swing drive mechanism 29 can be increased.

  In this embodiment, the lens driving magnet 19 is fixed to the inner peripheral surface of the cylindrical portion 14b of the cover member 14 made of a magnetic material, and the shake correction magnet 39 is fixed to the outer peripheral surface of the cylindrical portion 14b. Therefore, the cover member 14 functions as a back yoke. Therefore, the density of the magnetic flux passing through the lens driving coil 18 arranged opposite to the lens driving magnet 19 and the density of the magnetic flux passing through the shake correcting coil 38 arranged opposite to the shake correcting magnet 39 are increased. Is possible. Further, interference between the magnetic flux generated by the lens driving magnet 19 and the magnetic flux generated by the shake correction magnet 39 can be suppressed. Therefore, the lens drive mechanism 7 can appropriately move the lens in the optical axis direction, and the swing drive mechanism 29 can swing the camera module 3 appropriately.

  In this embodiment, the magnetic pole of the inclined surface 20c of the inclined surfaces 20c and 21c of the lens driving magnet 19 that opposes the shake correcting magnet 39 through the cylindrical portion 14b, and the lens driving magnet 19 through the cylindrical portion 14b. The lens driving magnet 19 and the shake correcting magnet 39 are fixed to the cylindrical portion 14b so that the magnetic poles of the inner side surface 42a of the inner side surfaces 42a and 43a of the shake correcting magnet 39 are different from each other. Therefore, an efficient magnetic circuit can be formed, and the driving force of the lens driving mechanism 7 and the swing driving mechanism 29 can be increased. In addition, since an attractive force acts between the lens driving magnet 19 and the shake correction magnet 39 via the tube portion 14b, the lens drive magnet 19 and the shake correction magnet 39 are fixed to the tube portion 14b. Fixing work becomes easy.

The lower surface of the fixed side fixing portion 28b is in contact with the upper end of the cylindrical portion 32b. Therefore, in the vertical direction, it is possible to fix the fixed side fixing portion 28b with reference to the upper end of the cylindrical portion 32b, and it is easy to ensure the relative positional accuracy in the vertical direction between the fixed side fixing portion 28b and the fulcrum portion 36. Become. Accordingly, the leaf spring 28 can be used to appropriately bias the camera module 3 toward the fulcrum portion 36, and the swinging motion of the camera module 3 can be further stabilized.

  In this embodiment, the thickness of the four side surfaces constituting the cylindrical portion 32b is relatively thin in the front-rear direction and the left-right direction, but the front-rear direction of the four side portions of the spacer member 33 formed in a frame shape. Since the thickness in the left-right direction is relatively large, it is possible to fix the fixed-side fixing portion 28b between the cylindrical portion 32b and the spacer member 33 in a stable state by using the thickness of the spacer member 33. become.

  In this embodiment, the leaf spring 28 is fixed so that the inner spring portion 28d and the outer spring portion 28e are substantially parallel to the front-rear direction or the left-right direction. For this reason, the spring constant of the leaf spring 28 in the front-rear direction is made relatively small by the action of the inner spring part 28d and the outer spring part 28e substantially parallel to the left-right direction, and the inner spring part 28d and outer spring part 28e substantially parallel to the front-rear direction. As a result, the spring constant of the leaf spring 28 in the left-right direction can be made relatively small. Therefore, the movable side fixing portion 28a can be smoothly moved in the front-rear and left-right directions. As a result, the camera module 3 can be smoothly swung even when the swing angle of the camera module 3 is increased.
