ABSTRACT:
A camera body includes at its rearside a frame having a rectangular window delineating the area of an image of an object projected onto the film and a pair of film guide longitudinal rails and is integrally formed of a reinforced polymeric resin or plastic material to reduce the weight thereof. Spacer members on which is abuttable a film pressure plate secured to the rear cover of the camera is made of metal of high machinability and are embedded in, clinched to, or threaded into the camera body so as to rearwardly project from the camera body. When abutting the spacer members, the pressure plate accurately positions a film guided by the film guide rails, in the direction perpendicular to a surface of the film, i.e., in the direction of the optical axis of a picture taking optical system since high accuracy is obtained by machining the spacer members.
