Claim Text:
1. A correcting optical device comprising: a fixed member configured to rotatably support a rotary member in a first plane that is perpendicular to an optical axis of a correcting lens; a movable member where the correcting lens is supported so as to be movable with respect to the fixed member in the plane in a second plane parallel to the first plane; and a driving unit that is disposed between the movable member and the rotary member and between the movable member and the fixed member, wherein the driving unit drives the movable member with respect to the fixed member in a direction in the second plane, and wherein the driving unit drives the rotary member to rotate around the optical axis of the correcting lens, so that the driving unit causes a restricting member to engage an engaging portion to restrict the translational movement of the movable member, and so that the driving unit causes the restricting member to disengage the engaging portion, to cause the movable member to be in a state capable of the translational movement, the restricting member being provided at the rotary member, and the engaging portion being provided at the movable member.
