範囲第１項記載の光学アダプタ。[Claims for Utility Model Registration] (1) It has an image receiving adapter that connects in the axial direction to a fiberscope containing an image fiber, and transmits an image of the end face of the image fiber supported by the image fiber holder to the image receiving device using the built-in image receiving lens. In the input optical adapter, the image receiving lens is housed so that the end face of the image fiber and the image receiving lens can be aligned coaxially with a predetermined distance apart as soon as the optical adapter engages with the image receiving adapter. An optical adapter having a built-in mechanism for pressing the lens case against the image fiber holder using a compression spring. (2) A utility model registration request characterized in that the certain distance is set such that the distance between the end face of the image fiber and the principal point on the end face side of the image fiber of the image receiving lens becomes the focal length of the image receiving lens. The optical adapter according to item 1. (3) The optical adapter according to claim 1 of the utility model registration claim, characterized in that the optical adapter has a contact point for supplying the power necessary to operate the image receiving device near the fitting part with the image receiving device. .
