PURPOSE:To automatically control the diopter of an optical device, by constituting it so that a diopter control means of an endoscope eyepiece device is related to a diopter control means of the optical device connected to the endoscope eyepiece device. CONSTITUTION:An endoscope eyepiece device 7 is provided with a member 8 for fixing an image guide 13, a lens cylinder 15 for holding an eyepiece lens 16, and a supporting cylinder 11. On the outside circumference of the supporting cylinder 11, a photographing cam cylinder 17 which penetrates a photographing cam hole 20 on its circumferential wall and has placed the first projecting part 21 on the upper end, a diopter cam cylinder 18 which penetrates the first cam hole 22 on its circumferential wall and its the recessed second diopter cam hole 23 on the upper end, and a diopter control ring 19 are fitted in order freely rotatably. To the lower end of an optical device connected to the eyepiece device 7, for instance, a camera, a fitting groove is formed, and it is fitted into the projecting part 21 so that a projecting part of the camera side hits and contacts with the cam hole 23. |
