<p>A film cartridge assembly having a film disk (45) and a relievable pressure plate (67) for holding the film flat against camera support rack during exposure. An opening (65) in the rear wall (43) of the cartridge assembly permits selective application of force to the pressure plate (67). Light is prevented from reaching the film (45) through the opening (65) by design of the rear wall (43) and pressure plate (67) to form a tortuous light path. With this structure a flexible membrane used in the prior art is eliminated permitting less restricted movement of the pressure pad.</p> |
