Claims (1)
を変換する光学系を具備するレンズ鏡筒と、当該
レンズ鏡筒の外周に沿つて延びる２つの支持アー
ムにより当該レンズ鏡筒を移動自在に支持すると
共に、主レンズに取り付けるためのマウントとか
らなる光学コンバータであつて、 当該レンズ鏡筒の外周に周方向で１８０度離れ
て２つの頭部付きのピン部材を植立し、当該ピン
部材の各々の軸部を、対応する上記支持アームの
長孔に貫入させてあり、 更に、各ピン部材の軸部を、当該レンズ鏡筒を
当該マウントに密接させた第１位置に係止すると
共に、当該レンズ鏡筒を当該マウントから引き出
した第２位置に係止するバネ材を配置した ことを特徴とする光学コンバータ。[Claims for Utility Model Registration] A lens barrel comprising an optical system that converts the focal length of the main lens at a conversion rate that differs depending on the orientation, and two support arms extending along the outer periphery of the lens barrel. An optical converter that movably supports a barrel and includes a mount for attaching it to a main lens, in which two pin members with heads are planted on the outer periphery of the lens barrel at a distance of 180 degrees in the circumferential direction. The shaft portion of each pin member is inserted into the corresponding elongated hole of the support arm, and the shaft portion of each pin member is located at a first position where the lens barrel is brought into close contact with the mount. An optical converter characterized in that a spring member is disposed for locking the lens barrel at the mount and locking the lens barrel at a second position where the lens barrel is pulled out from the mount.
