  • Publication number: 20190018258
    Abstract: To draw a flexible printed circuit board in a small space with high flexibility in an optical unit with shake correction function. In an optical unit with rolling correction function, a first flexible printed circuit board for an imaging element is drawn around an optical axis of the optical unit with rolling correction function such that the first flexible printed circuit board is wound by substantially a turn in a circumferential direction at an identical height in an optical axis direction. Furthermore, in a portion wound in the circumferential direction (i.e., a connection part), one end and the other end in the circumferential direction are at an identical height in the optical axis direction. Furthermore, a second flexible printed circuit board for a rolling magnetic driving mechanism and a third flexible printed circuit board for a swing magnetic driving mechanism are also drawn in a similar manner.

  • Publication number: 20190020799
    Abstract: An optical unit with rolling correction function is provided and performs rolling correction by fixing a circuit board on which an imaging element is mounted and a heat dissipating member to a rotation member, transmitting heat from the circuit board to the heat dissipating member, and rotating the rotation member. A rotation shaft of a rotation supporting mechanism is fixed to the rotation member via the heat dissipating member. Accordingly, it is possible to dissipate heat by transmitting heat that is generated from the imaging element, from the circuit board to the heat dissipating member, and then transmitting the heat from the heat dissipating member to the rotation shaft. The imaging element and the heat dissipating member overlap with the rotation shaft at an identical position when the imaging element and the heat dissipating member are seen from an optical axis direction.

  • Publication number: 20180284569
    Abstract: In an optical unit with shake correction function, a first stopper mechanism configured to define a swinging range of a movable member is composed of: a first projection part for stopper and a second projection part for stopper, both of which are provided in a camera module; and a projection portion (abutment target) of a holder bottom plate member. Therefore, when the first projection part for stopper and the second projection part for stopper; and the projection portion of the holder bottom plate member abut against each other and then movement in the Z axis direction of the movable member is restricted, the camera module does not move in the Z axis direction any more. Accordingly, the camera module does not slip off from a camera module holder of the movable member.

  • Publication number: 20180129066
    Abstract: An optical unit includes a subject-side rotary bearing part located on a subject side of an optical module and an image-side rotary bearing part located on an image side of the optical module. The two rotary bearing parts disposed on both the subject side and the image side of the optical module make it possible to restrain the tilt of the optical module and restrain backlash during a rotation of the optical module around an optical axis. This prevents the optical module from becoming a cantilever state and a twisting load from being applied due to an impact. Thus, it is possible to reduce the possibility of breakage of the rotary bearing parts due to an impact. A movable body includes a rotary bearing holder which swingably supports the optical module. A rolling magnetic-drive mechanism is disposed between the rotary bearing holder and a fixed body.
