    摘要： An optical unit may include a fixed body, a movable module w rich holds an optical element, a swing support point which swingably supports the movable module, and a shake correction drive mechanism structured to swing the movable module with the swing support point as a swing center. The swing support point may be structured of an abutte d portion of two members in an optical axis direction between a bottom part of the movable module and a bottom part of the fixed body. At least one of the two members may be made of elastic material.

    摘要： An optical unit with shake correcting function may include a movable module having a lens, a fixed body supporting the movable module, a shake detection sensor for detecting shake of the movable module, and at least one pair of magnetic drive mechanism for shake correction which is structured on both sides of the movable module so that the movable module is swung with respect to the fixed body on the basis of detection result of the shake detection sensor to correct the shake of the movable module. The magnetic drive mechanism for shake correction is disposed so that a shake correction magnet is held by the fixed body and a shake correction coil is held by the movable module. Further, a shake correction coil may be disposed in a first region, where magnetic lines of force generated by a shake correction magnet are directed in directions generally going away from a supporting point part and/or a second region where magnetic lines of force generated by the shake correction magnet are directed in directions generally going toward the supporting point part.

    摘要： The lens drive device is equipped with a first supporting body that holds the lens and is movable in the direction of the optical axis, a second supporting body that holds the first supporting body, a fixed body that holds the second supporting body in a manner enabling movement in directions that are roughly orthogonal to the optical axis direction, a first drive mechanism for driving the first supporting body, a second drive mechanism for driving the second supporting body in a first direction, and a third drive mechanism for driving the second supporting body in a second direction. The first supporting body is supported by the second supporting body by means of first supporting members which are formed from an elastic material; and the second supporting body is supported by the fixed body by means of second supporting members, which are formed from an elastic material.
