Abstract

PURPOSE:To make a cemara main body flat, by rotating one inverting mirror to use the camera main body using a disc-shaped film as a single-lens reflecx camera. CONSTITUTION:A photographic lens 10 is attached to the aperture part in the front of the side wall of a flat camera main body 2, and an exposure aperture 3 is provided on a plane parallel with an optical axis 11 of the photographic lens. One inverting mirror 13 turnable between the photographing position where an object beam transmitted through the photographic lens is inverted toward the exposure aperture 3 at about 90 deg. and the observing position where inverts this object beam toward the optical path of a finder provided in the side part of the camera main body 2, a mirror holdig member 18 which has a driving shaft 18C inclined at about 45 deg. to the flat face of the camera main body 2, and a mirror driving member 29 which turns this holding member 18 between the photographing position and the observing position are provided.
