摘要： An optical unit includes: a reflection portion that reflects an incident light flux incident from outside on a reflection surface in a reflection direction from an incident direction toward an imaging element; a movable body having the reflection portion and a holder supporting the reflection portion; a fixed body; a rotation support mechanism that causes the movable body to rotate with respect to the fixed body with an axial direction as a rotation axis; and a drive mechanism having a magnet and a coil and causing the movable body to rotate with respect to the fixed body. The magnet is provided at a position not contacting the reflection portion in the holder and on a back side of the reflection surface, and has a parallel surface parallel to the reflection surface. The coil is provided at a position opposing the magnet in the fixed body.

摘要： A drive device is provided and includes: a movable body including an attachment part, to which an optical module is attached; a fixed body; and a support part rotatably supporting the movable body about an optical axis of the optical module attached to the attachment part with respect to the fixed body. The movable body includes a movable body-side fixing part, to which a flexible printed circuit pulled out of the optical module is fixed. The fixed body includes a fixed body-side fixing part, to which the flexible printed circuit is fixed. And, a portion between the movable body-side fixing part and the fixed body-side fixing part in a region along an outer periphery of the fixed body is set as a region drawn around in an attitude causing a thickness direction of the flexible printed circuit to be directions both orthogonal to a direction of the optical axis.

摘要： A movable unit of an optical module having an image shake correction function is supported by a gimbal mechanism so as to be rotatable around a first axis R1 and a second axis R2. The movable body is driven by a shake-correction magnetic drive mechanism including magnets and fixed to the movable body. The movable body further includes a lens-moving magnetic drive mechanism to move a lens module in an optical axis direction. The lens-moving magnetic drive mechanism includes a lens-moving coil fixed to the lens module 7 and a lens-moving magnet disposed radially outward of the lens-moving coil. The magnets and also serve as the lens-moving magnet and are disposed radially outward of a triaxial intersection.

摘要： An optical unit with a shake correction function may include a movable body having an optical element, a turnable support mechanism structured to turnably support the movable body around an optical axis of the optical element, a fixed body supporting the movable body through the turnable support mechanism, a magnetic rolling drive mechanism structured to turn the movable body, and an angular position return mechanism structured to return the movable body to a reference angular position around the optical axis. The magnetic rolling drive mechanism may include a coil and a magnet facing the coil. The magnet is polarized and magnetized in a circumferential direction. The angular position return mechanism includes a magnetic member attached to the movable body and, when the movable body is located at the reference angular position, an imaginary plane which includes a magnetizing polarized line of the magnet passes a center of the magnetic member.

摘要： 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.

摘要： An optical unit includes a movable body, a fixed body surrounding the movable body, a turning support mechanism turnably supporting the movable body with respect to the fixed body, and a drive mechanism including a coil disposed on the movable body or the fixed body, and multiple magnets disposed on the other of the movable body and the fixed body at a position facing the coil. An end part in an optical axis direction of the coil is bent in a direction approaching a turning axis of the movable body, and the magnets are disposed side by side so that faces of the magnets facing the coil become approximately parallel to the coil when viewed in a direction of the turning axis in comparison with a case that the magnets are arranged along the optical axis direction.
