ABSTRACT:
In a photographic film cassette, rotation of a spool in a direction of unwinding a photographic film causes a film leader to advance to an outside of a cassette shell. An exposed film is drawn out of the cassette shell after advancing the film leader for developing the exposed film in a state with a film trailer attached to the spool so as to keep the cassette shell reusable. The exposed film is wound up into the cassette shell after development. After development, the spool is rotated in the unwinding direction in a printer in order to advance the film leader outward such that the exposed film can then be drawn out of the cassette shell frame by frame for subjecting the developed film to printing in a state with the film trailer attached to the spool. Thereafter, the spool is rotated in a direction of winding up the developed film for containing the exposed film in the cassette shell.
