の自動焦点調整装置。[Scope of Claim for Utility Model Registration] 1. A single-lens reflex camera with interchangeable lenses that adjusts focus by displacing the mount on which the lens is attached in the direction of the optical axis, and the mount seat on which the mount is fixed has a mount that corresponds to the setting value of the lens. An electric sliding resistance member that obtains calibration value information, a linking member that connects to the aperture ring of the photographic lens, and an aperture relay ring that releases the aperture of the photographic lens from open to a predetermined aperture during shooting are provided. Features an automatic focus adjustment device. 2. One end of the connecting part of the aperture relay ring is engaged with the aperture rotating lever of the photographic lens, and the other end is bent in the direction of the optical axis of the photographic lens and is connected to the aperture on the body side within the stroke area that is displaced for focus adjustment. An automatic focus adjustment device according to claim 1, characterized in that the automatic focus adjustment device is adapted to maintain engagement with a lever. 3. The bending protrusion, which is the connecting part of the iris relay ring, is arranged by cutting out a part of the side wall thickness of the mirror box provided between the mirror operating mechanism of the camera body and the first mirror. An automatic focus adjustment device according to claim 2 of the utility model registration claim.
