发明名称 Film loading mechanism of a camera
摘要 In a camera capable of changing a photographing frame size defined in a photographing aperture, frame size limit members are moved, at an initial stage of film feeding, to a position to form a frame size smaller than an ordinary frame size or to a position to intrude further into the aperture by exceeding a position at which the frame size smaller than the ordinary frame size is formed, irrespective of a selecting position of a frame size changeover operation member, thereby preventing a leading end portion of the film fed out of a film cartridge from entering the aperture during initial film feeding.
