べくなしたこと、 を特徴とする自動焦点調節用測距検知器。[Claims for Utility Model Registration] Comprising a light projecting member and a light receiving member that receives the return light emitted from the light projecting member and reflected by the subject through a light receiving lens, the light receiving member and the photographing optical system are in focus. A rangefinder for automatic focus adjustment that works in conjunction with a ring to focus, in which a light-receiving lens and a light-receiving member are integrally formed in a light-tight manner by a lens barrel, and the optical The center is rotatably supported by a support pin, and this rotation movement is linked with the movement of the focus ring of the photographing optical system to rotate the lens barrel about the support pin, thereby moving away from the subject. A distance measuring detector for automatic focus adjustment, characterized in that the returning light beam of the light is captured along the optical axis of a light receiving member.
