のミラー駆動装置。 A first mirror that moves between a lowered position that guides the subject light to the viewfinder optical system and a raised position where it exits from the photographing optical path, and a first mirror that is pivoted to the back of the support frame of the first mirror, and the first mirror is moved to the lowered position. When the change occurs, the first mirror rotates in one direction and guides the light that has passed through the first mirror to the light receiving section at a position away from the first mirror.
In a single-lens reflex camera equipped with a second mirror that rotates in the other direction when the mirror moves to a raised position and approaches the first mirror, the second mirror support frame is provided with an extension part, and the second mirror is provided with an extension part. The extension part is provided with an interlocking protrusion, and further provided with an arm rotatably pivoted to the camera fixing part, and the arm is provided with a guide hole in which the interlocking protrusion slides at the pivoting part thereof. A mirror drive device for a single-lens reflex camera, characterized by comprising a biasing member that applies a unidirectional turning force.
