PROBLEM TO BE SOLVED: To provide an endoscope that can acquire high-quality image by disposing a movable lens frame in an adjustment position with excellent reproducibility.SOLUTION: When controlling the movable lens frame 65 for advance movement, the endoscope controls an actuator mechanism 70 to apply first turning force for pushing the operation stem 65a to one side wall of a slit 61a in addition to applying pushing force for pushing the operation stem 65a to a front-side stopper part 61b and, when controlling the movable lens frame 65 for retreat movement, the endoscope controls the actuator mechanism 70 to apply second turning force for pushing the operation stem 65a to the other side wall of the slit 61a in addition to applying traction force for pushing the operation stem 65a to a rear-side stopper part 68.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】移動レンズ枠を再現性よく調整位置に配置して高品質な撮像画像を得ることができる内視鏡を提供する。【解決手段】移動レンズ枠65を進出動作させる際に、アクチュエータ機構70により、操作桿65aを前側ストッパ部61bに押し付ける押圧力に加えて操作桿65aをスリット61aの一方の側壁に押し付ける第1の回転力を付与し、移動レンズ枠65を退避動作させる際に、アクチュエータ機構70により、操作桿65aを後側ストッパ部68に押し付ける牽引力に加えて操作桿65aをスリット61aの他方の側壁に押し付ける第2の回転力を付与する。【選択図】図3
