Abstract
Guide rails for positioning a film are formed on a shutter block. The guide rails project through an opening in a thin back plate of a camera body to regulate the position of a film drawn from a film cartridge chamber into a spool chamber. A frame aperture formed in the shutter block regulates the exposable area of a frame of film. The shutter block is fixable to a box-shaped mirror housing, which is then fixed to the camera body and a supporting plate.
