Patent ID: 8224169

Claim:
An optical unit with shake correcting function comprising: a movable module in which at least a lens is supported on a support body; and a fixed body which supports the movable module; wherein the movable module is supported on the fixed body so as to be displaceable in a direction intersecting an optical axis of the lens; and wherein a movable module drive mechanism is provided at two positions, with the optical axis interposed therebetween, between the movable module and the fixed body and the movable module drive mechanism is structured to generate magnetic drive force to displace the movable module in a direction intersecting the optical axis; wherein the movable module is an image-pickup unit in which an imaging element is held by the support body, the lens is included in a movable body which is movably supported on the support body in the optical axis direction, the lens drive mechanism which magnetically drives the movable body in the optical axis direction is supported on the support body in the movable module, movable module drive magnets are held by the movable module and the movable module drive coils are held by the fixed body, the movable module is provided with a cover part surrounding the movable body on an outer peripheral side, the lens drive mechanism is provided with a lens drive coil which is held by an outer peripheral face of the movable body and a lens drive magnet which is held by an inner peripheral face of the cover part, and the movable module drive magnets are held by an outer peripheral face of the cover part; wherein three directions perpendicular to each other are set to be an X-axis, a Y-axis and a Z-axis, and a direction along the optical axis is set to be the Z-axis, the movable module drive mechanism comprises between the movable module and the fixed body: a first movable module drive mechanism provided at two positions and aligned in an X-axis direction with the optical axis interposed therebetween, and structured to generate magnetic force to rock the movable module on the fixed body in one of the X-axis direction and a Y-axis direction, and a second movable module drive mechanism provided at two positions and aligned in a Y-axis direction with the optical axis interposed therebetween, and structured to generate magnetic force to rock the movable module on the fixed body in an other of the X-axis direction and the Y-axis direction.
