An aperture frame that determines the screen size is provided within the camera body so as to be movable in the optical axis direction of the photographic lens, and an aperture frame drive member that moves the aperture frame toward and away from the film is provided. The member is mechanically interlocked with the film winding and rewinding mechanism, so that the aperture frame approaches the film when the film winding is completed, and moves away from the film during the film winding and rewinding operations. A camera screen size regulating device characterized by:
