Abstract:
1. A vibration correcting device comprising: a lens unit having an optical axis; a movable member holding the lens unit, which makes the lens unit movable within a plane orthogonal to the optical axis; a fixed member limiting the movement of the movable member in the optical axis direction; a ball disposed between the movable member and fixed member, which can roll between the movable member and fixed member and make relative movements of the movable member and fixed member possible; a vibration detecting unit, which outputs vibration information corresponding to vibration; and a limiting portion limiting the movement of the ball, wherein the size of the limiting portion in a driving direction of the movable member is set so that the ball does not contact the limiting portion even when the ball rolls from the center of the limiting portion by half of a maximum movement amount of the movable member, the maximum movement amount being (a) the maximum movement amount when the movable member is mechanically moved or (b) the maximum movement amount when the movable member is moved to correct an image vibration.
