Claims (1)
ー昇降枠と、 該ミラー昇降枠に連動して往復旋回可能なミラーと、 該ボディーの後方に配置されているシャツタ膜と、から
成り、 非撮影状態において該ミラーが45°傾斜位置に保持さ
れていて撮影光をファインダへ反射させる様な1眼レフ
カメラにおいて、 前記非撮影状態の時に前記ミラー昇降枠の先端部によっ
て撮影光を遮断してシャツタ膜への照射が行なわれない
ようにしたことを特徴とするシャツタ膜焼損防止構造。[Scope of Claim for Utility Model Registration] A camera body, a mirror lifting frame that is pivotally supported near the top of the body and is capable of reciprocating rotation, a mirror that can be rotated back and forth in conjunction with the mirror lifting frame, and the rear of the body. In a single-lens reflex camera in which the mirror is held at a 45° tilted position in the non-photographing state and reflects the photographing light to the viewfinder, the mirror is disposed in the non-photographing state. A structure for preventing burnout of a shatter film, characterized in that the tip of a mirror elevating frame blocks photographing light to prevent irradiation of the shatter film.
