Zusammenfassung: | To allow a click mechanism and a cam mechanism to be disposed in a narrow space in an operation part by a simple structure, and achieve a reduction in size and weight of the operation part.SOLUTION: An endoscope operation device includes: a movable lens frame 36 that moves forward and backward between a super-magnified observation position T2 and an ordinary observation position W through a magnified observation position T1 by operation of a rotary operation lever 18; a movable lens 36a held by the movable lens frame 36; a cam plate 49 for transmitting rotation of the rotary operation lever 18 to the movable lens frame 36, in which a cam pin 50 rotated together with the rotary operation lever 18 is fitted into a cam groove 49a integrally operated with the movable lens frame 36; and a notch 49d provided at a position corresponding to the magnified observation position T1 on a cam surface 49b formed in the cam groove 49a at a side close to the rotary operation lever 18.SELECTED DRAWING: Figure 5
【課題】簡単な構造で、操作部内の狭隘な空間にクリック機構とカム機構とを配設することが可能で、操作部の小型軽量化を実現することができるようにする。【解決手段】回動操作レバー18の操作により超拡大観察位置T2から拡大観察位置T1を経由して通常観察位置Wに至る間で進退される移動レンズ枠36と、この移動レンズ枠36に保持された移動レンズ36aと、移動レンズ枠36と一体に動作するカム溝49aに回動操作レバー18と共に回動されるカムピン50が嵌入されて回動操作レバー18の回動を移動レンズ枠36に伝達するカムプレート49と、回動操作レバー18に近い側のカム溝49aに形成したカム面49bの、拡大観察位置T1に対応する位置に設けたノッチ49dとを備える。【選択図】図5 |
