Abstract

PURPOSE: To reduce the turning amount of photographing interlocking cam and ease the mounting operation of the photographing device by having the photographing positioning cam hole and diopter adjusting cam hole for the eyepiece and sandwiching a diopter adjusting pin in the two cam holes.
CONSTITUTION: The positioning device 1 incorporated in the eyepiece part 2 of an endoscope is constituted by a movable barrel 4 to which an eyepiece 3 is supported, a stationary barrel 5 which fits thereto, a diopter adjusting cam barrel 6 fitting thereto, a photographing interlocking cam barrel 7 which fits thereto and a diopter adjusting ring 9 for sliding the diopter adjusting pin 8 studded to the movable barrel and cam barrel 6 in the optical axis direction. At the time of taking a picture of images, the cam barrel 7 is turned by the interlocking arm and since the pin is held energized in the arrow c direction by rhe stretching force of a spring 19, it advances and turns from the cam face 23a along the cam face 21b. When the cam barrel 7 turns further, it retreats in the optical axis direction along the cam face 21a while abutting against the cam face 23b and goes beyond the cam face 23b, thus coming to make contact with the face 23d, and it stops while making elastic contact with the face 23d. Photographing is then performed.
