Abstract: An optical unit with a shake correction function include a fixed body, a movable body having an optical element, a swing support mechanism swingably supporting the movable body, and a shake correction drive mechanism structured to swing the movable body. The movable body includes a first abutting part abutted with a first stopper part of the fixed body at a time of a maximum swing, and a second abutting part abutted with a second stopper part of the fixed body at a time of a movement in an optical axis direction. The second stopper part and the second abutting part are separated so as not to contact with each other when the movable body is swung, and a separated distance along the optical axis direction between the second stopper part and the second abutting part is smaller than a separated distance between the first abutting part and the fixed body.

Abstract: A coil unit may include coil holding member configured to hold a coil; and a coil held by the coil holding member and formed by a conducting wire in a wound state. A direction perpendicular to a length direction of the conducting wire is a thickness direction of the coil. The coil holding member may include an abutment surface configured to abut against one end surface in the thickness direction of the coil, a convex unit protruding from the abutment surface and around which the conducting wire is wound, and a coil pressing unit extending from a front end surface of the convex unit and configured to press the other end surface in the thickness direction of the coil.

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.

Abstract: Regarding an optical unit, a swing driving magnet is held at a holding area of a fixed member in such a manner that the swing driving magnet is movable, and a position-recovering magnetic member is held on a movable unit at a position where the position-recovering magnetic member is able to face the swing driving magnet (Step ST1). Next, a deviated amount between the axis line of the optical unit and the optical axis of an optical module is obtained (Step ST2). Then, the swing driving magnet is moved.

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.

Abstract: To provide a rolling magnetic driving unit that can be employed for both of an optical unit with shake correction function that causes an optical module to swing and rotate and an optical unit with shake correction function that causes the optical module to rotate, a second unit (i.e., a rolling magnetic driving unit) includes: a rotation seat; and a fixation member that supports the rotation seat via a bearing mechanism. The rotation seat and the bearing mechanism configure a rotation-supporting mechanism. The rotation-supporting mechanism supports a holder, which supports the optical module such that the optical module is able to swing, such the holder is able to rotate on the axis. Furthermore, the second unit includes a rolling magnetic driving mechanism, which includes a rolling driving coil that is held by the rotation seat and a rolling driving magnet that is held by the fixation member.

Abstract: An optical unit may include a movable member include a camera module comprising an optical element and an image pickup element positioned on an optical axis of the optical element; and a camera module holder comprising a cylindrical holding part to hold the camera module from an outside; a swingable supporting mechanism to swingably support the movable member between a reference position and a tilt position; and a supporting member to support the holding part via the swingable supporting mechanism. When the movable member is set in the reference position, seen from an object side in a direction of the axis, the holding part may include a visible portion configured to enable a visual check without an occurrence of an overlap with respect to the camera module, the swingable supporting mechanism, and the supporting member.
