る一眼レフレツクスカメラの可動ミラー装置。 In a single-lens reflex camera that performs photometry or focus detection using part of the light from the photographing lens that passes through a movable mirror that can be retracted out of the photographic optical path from the viewfinder observation position on the photographic optical axis, the front surface of the movable mirror The entire area of the mirror is formed into a semi-transparent mirror, and a black paint is applied to almost the entire surface of the mirror, leaving the light ray passing portion necessary for photometry or focus detection on the back surface, so that the paint film adheres to the mirror, and the paint film is adhered to the surface of the mirror. A movable mirror device for a single-lens reflex camera, characterized in that it is configured to absorb internally reflected light rays.
