Abstract: An optical unit may include a movable member configured to hold an optical module; a rotation supporting mechanism to support the movable member such that the movable member rotates on an optical axis; a fixing member to support the movable member; a rolling magnetic driving mechanism to rotate the movable member on the optical axis; and an optical module flexible printed circuit board. The movable member may include a holder configured to rotate on the optical axis while holding the optical module. The holder may include a fixing part to which the optical module flexible printed circuit board is fixed. The optical module flexible printed circuit board may include a connector inserting part connected to the fixing member or to a supporting member; and a flexed part formed between the connector inserting part and a portion fixed to the fixing part.

Abstract: An optical unit with a shake correction function may include an optical module comprising an optical element; a swing support mechanism structured to swingably support the optical module between a reference posture in which a preset axis and an optical axis are aligned, and an inclined posture in which the optical axis is inclined with respect to the axis; a holder structured to support the optical module via the swing support mechanism; a rotation support mechanism structured to rotatably support the holder around the axis; a fixed body structured to support the holder via the rotation support mechanism; a swing magnetic drive mechanism structured to swing the optical module; and a rolling magnetic drive mechanism structured to rotate the holder. The rotation support mechanism may include a rotation bearing that supports the holder on a subject side of the swing support mechanism.

Abstract: An optical unit with a shake correcting function may include a fixed body, a movable body holding an optical element, a swing support point which supports the movable body so that the movable body is capable of swinging, a spring member formed in a plate shape for urging the movable body toward the swing support point, a shake correction drive mechanism structured to swing the movable body with the swing support point as a swing center, a first stopper part which is protruded in a direction perpendicular to the optical axis direction on a front side in the optical axis direction of the movable body with respect to the spring member for determining a moving range of the movable body, and a second stopper part which is structured to face the first stopper part in the optical axis direction through the spring member on the rear side in the optical axis direction of the fixed body with respect to the spring member for determining a moving range of the movable body in the optical axis direction by restricting movement of the first stopper part.
