Abstract
A lens-fitted photographic film unit comprises a main body having a photograph-taking function and a rear cover for shielding the rear of the main body in a light-tight manner. The main body has a film supply chamber and a film take-up chamber both of which are provided with respective bottom openings. The film supply chamber is provided with a first side edge limiting plate so as partially to shield the bottom opening. The rear cover is provided with a cap for closing the bottom opening of the film supply chamber and a second side edge limiting plate. A winding shaft is engaged with a film leader of a photographic film, drawn from a photographic film cassette and positioned in a film supply chamber. Similarly, the empty photographic film cassette is positioned in a film take-up chamber. When the rear cover is attached to the main body, an arc-shaped cutout of the first side edge limiting plate faces an arc-shaped cutout of the second side edge limiting plate to form a circular opening through which the winding shaft is inserted and withdrawn. The winding shaft is rotated in the opening to wind up the film thereon. After forming a film roll, the winding shaft is pulled out of the film roll through the opening and the cap is closed to seal the unit light-tightly.
