するミラー位置決め機構。In a single-lens reflex camera that has a mirror that is retracted out of the optical path during photography and is normally positioned obliquely on the optical path to reflect incident light toward the viewfinder, the mirror or a member integrated with the mirror is When the mirror is pressed against the positioning member and the mirror is in the inclined position, the biasing force acts in the direction of pressing the mirror against the positioning member, and as the mirror retreats out of the optical path, the direction in which the biasing force acts changes A mirror positioning mechanism characterized by having a spring arranged so as to approach a line passing through the center of rotation.
