支持機構。[Scope of Claim for Utility Model Registration] When the main mirror, which is rotatably supported within the mirror box, is in the observation position where it guides the light beam transmitted through the photographing lens to the viewfinder section, the main mirror is rotatably supported by the main mirror. The sub-mirror is located at a position where it reflects the light that has passed through the transparent or semi-transparent part of the main mirror and guides the reflected light to the light-receiving element.
In a single-lens reflex camera, when the main mirror is in a photographing position where it is retracted out of the photographing optical path, the sub-mirror follows the main mirror and is also retracted out of the photographing optical path. A fixed member such as a side plate of a mirror box that rotatably supports one of the shafts, and a fixed member such as a side plate of the mirror box that rotatably supports the other support shaft of the main mirror, and is adjusted vertically with respect to the fixed member. A support member that can be attached freely; and a stopper that is integrally provided with the support member and that stops the submirror by coming into contact with the submirror at a position where the submirror guides the reflected light to the light receiving element. Mirror support mechanism for single-lens reflex cameras.
