Claims

[Claims for Utility Model Registration] 1. An auxiliary optical member inserted into the optical path of an optical device, an optical member holding member for holding the numbering of the auxiliary optical part, and an optical member holding member for rotatably holding the optical member and holding the optical member. The auxiliary optical member is removably inserted into the insertion portion formed in the device, and the auxiliary optical member is inserted into the device as described in 1. an insert holding member located in the optical path; an operating member provided on the insert holding member that is operated from outside the optical equipment when attached to the optical device; and an operating member that controls the operation of the operating member. A shaft-insertion type optical member comprising a rotation transmitting means for transmitting transmission to a holding member and rotating it. 2. '';2. The insertion type optical member according to claim 1, wherein the operating member is a knob for attaching and detaching the insertion type optical member to and from the 7-lens lens barrel. 3. The rotation transmission means includes an operating member and an optical member holding part,
The plug-in optical member according to claim 1 or 2, which is a gear means for connecting members.・ . 4. The insertion-type optical member according to claim 1 or 2, wherein the rotation transmission means is a belt connecting means that connects the rod part and the optical member holding part 1,'. .
