Abstract:
An optical unit with a shake correction function include a movable body having an optical module and a holder surrounding the optical module, a swing support mechanism swingably supporting the movable body, a fixed body, and a shake correction drive mechanism. The optical module has a protruded part, and the holder has a position restriction part with which the protruded part is abutted. The fixed body includes a case accommodating the holder, and the case includes an outer frame part surrounding the holder and a projecting part projecting to an inner peripheral side from an end part on an image side of the outer frame part. The projecting part has a stopper part overlapping with the holder, and the protruded part and the position restriction part are located on an inner peripheral side with respect to the projecting part when viewed in the optical axis direction.
Abstract:
A shake correction optical unit with a shake correction function may cause a movable body including an optical module to swing around an X axis and a Y axis that are perpendicular to an optical axis L. A flexible printed board may include a second folded portion drawn from the movable body in a +Y direction, and bent in a direction of the optical axis L and folded once; and a first folded portion bent to extend from the second folded portion in the +Y direction and folded once. At least one of the second folded portion or the first folded portion may be thus easily bendable when the movable body swings in either direction around the X axis or around the Y axis.

An optical unit having a shake correction function may include a movable body including an optical module, a fixed body that supports the movable body via a gimbal mechanism, and a shake correction drive mechanism that swings the movable body around a first axis and a second axis intersecting each other. The shake correction drive mechanism may be disposed on two intersecting faces out of four faces of the movable body. A first flexible printed circuit board may be led out from one of the two faces, of which the shake correction drive mechanism is not disposed on either.

An optical unit with a shake correction function may include a movable module holding an optical element, a support body including a body part surrounding the movable module, a gimbal mechanism including a movable frame having elasticity and configured to swingably support the movable module between the movable module and the support body, a spring member connected to the movable module and the support body for holding posture of the movable module, and a shake correction drive mechanism configured to swing the movable module. When a natural vibration frequency of the movable frame is “fa”, a natural vibration frequency of the spring member is “fb”, and a vibration frequency band of a movable body on which the support body is mounted is “fw”, the natural vibration frequency “fa” and the natural vibration frequency “fb” are shifted from the vibration frequency band “fw”. Further, it may be preferable that a difference between the natural vibration frequency “fa” and the natural vibration frequency “fb” is set to be 135 Hz or more.
