Abstract: A lens frame supporting mechanism includes a spherical surface that is a specified region of the outer surface of a lens frame for holding an optical system and that acts as a driven and supported member. The spherical surface is supported by spherical rotators serving as supporting driving members. The lens frame is driven to rotate by means of the spherical rotators that are in contact with the lens frame, thus shifting the orientation of the optical axis of the optical system. The lens frame is rotated while being restrained from rotating about the optical axis by means of a guide ditch and a guide pin formed in the spherical surface of the lens frame. This lens frame supporting mechanism has materialized a simple supporting mechanism and a compact lens frame, and realizes a reduced load to a rotation actuator.
