A correcting optical device including: a fixing member; a rotating member; a movable member; first and second drive units; and at least first and second contact members. For the regulation of movement of the movable member, rotational driving force is produced by the first and second drive units and, the rotating member is rotated in the opposite direction of the rotational direction of the movable member after the movable member is rotated to be brought into contact with the first contact member, whereby translational movement of the movable member is regulated. For image deflection correction, rotational driving force in the opposite direction of the rotational force is produced and, the rotating member is rotated in the opposite direction of the rotational direction of the movable member after the movable member is rotated to be brought into contact with the second contact member, whereby regulation on the movable member is released. |
