" should be corrected to "schematic plan,"

Claims

[Scope of Claim for Utility Model Registration] A cam cylinder with a cam hole is slidably inserted into a support cylinder in which an eyepiece is movably inserted in the optical axis direction, and a camera for photographing an observation area is attached and rotated. It has a lens moving mechanism that rotates the cam barrel in conjunction with the camera and moves the eyepiece to the photographing position, and the shutter of the camera is driven from the power source of the endoscope through a lead wire provided on the support barrel. In an endoscope eyepiece that is installed with the current-carrying terminal exposed in order to supply power to the mechanism, part of the lead wires provided on the support tube is separated and separated, and the separated lead wires are connected to each other. A conductor is provided on the opposing end sides of the camera, and an energizing means is provided for bringing the separated conductors into contact with each other and energizing them when the cam barrel is rotated to the photographing position. Electric shock prevention mechanism for endoscope eyepiece.
