PURPOSE:To confirm that an attachment is attached correctly even in the dark by generating a sound when the fitting cylinder part of the attachment body is attached to the eyepiece part of an endoscope. CONSTITUTION:The guide pin 16 of the eyepiece part 3 of an endoscope is fitted in the longitudinal hole part 26 of the guide hole 25 of the fitting cylinder 22 of a camera side 2. At this time, an engagement piece 12 enters an engagement groove 13 through an insertion hole 15. As the camera 2 is rotated, the engagement piece 12 while pressed strongly by a leaf spring 35 moves in the groove 13 to engage a fitting jaws 14 at a prescribed angle. In this case, a rotary ring 29 is jointed to the surface of the fitting jaws 14 of a supporting cylinder 4 and then rotates together with the supporting cylinder 14. When it rotates at a prescribed angle, a ball 33 falls in a clip hole 31 to generate a sound. Therefore, it is confirmed even in the dark that the attachment is attached correctly. |
