ABSTRACT:
The present invention includes: a taking lens including a lens group; a distance ring that is operated to rotate around the taking lens; an LD roller capable of rotating in conjunction with the rotational operation of the distance ring; a transducer that is in contact with the LD roller and capable of moving around the taking lens relative to the LD roller; and a rotatable frame member that is capable of moving around the taking lens within a predetermined angle range and supports the transducer, upon the distance ring being rotated manually, the rotatable frame member being rotated via the LD roller and the transducer, and upon the transducer being driven by a drive signal, the transducer moving relative to the LD roller, thereby the rotatable frame member being rotated around the taking lens to move a focusing lens in the taking lens to move in an optical axis direction.
