Claims

[Claims for Utility Model Registration] A first lens frame that is movable back and forth along the optical axis and has a diopter adjustment pin and an eyepiece; a second lens frame that is movably fitted into the lens frame and has a shooting position setting pin; and a second lens frame that engages with the diopter adjustment pin to move the lens frame to a position where a desired diopter is obtained. The diopter adjustment part has a diopter adjustment cam surface that is rotated around the optical axis, and the diopter adjustment cam surface is set within the movement range of the lens frame part by the diopter adjustment cam surface. a diopter adjustment position canceling cam surface that engages with the diopter adjustment pin to move the lens frame beyond the photographic position and to one end of the movement range; and a second lens frame in the lens frame. and a photographing position setting cam surface that engages with the photographing position setting pin in order to move the camera to a predetermined photographing position, and can be rotated by a predetermined angle around the optical axis in conjunction with the mounting operation of the photographing device, etc. 1. A moving device for an eyepiece lens in an eyepiece section of an endoscope, comprising a photographing position setting section.
