A lens-fitted photographic film unit provided with a shutter, a taking lens and a film wind-up mechanism has a film unit housing, an exposure station, a film supplying chamber and a film take-up chamber, which is provided with a spool for tightly winding exposed film. A film outlet is provided with the film take-up chamber to let out a film leader to the outside when rotating the spool in the unwinding direction. Light trapping fabric is attached in the film outlet to trap external light. In a preferred embodiment, the friction coefficient of a back surface is 0.35 or less with respect to an emulsion surface, whereas the dynamic friction coefficient is 0.36 or less with respect to a steel ball. A film processor for developing the film in the film unit is provided with a holder for loading film units. A spool rotating mechanism rotates the spool to automatically let out the film. Roller pairs are provided to feed the film through the film outlet toward a processor unit, which serves to process the exposed film.
A photographic processing system comprising a photographic film unit and a processor for subjecting said film unit to processing;
A processor for subjecting a lens-fitted photographic film unit in which rotation of a spool in a film take-up chamber in a second direction opposite to a first direction for winding an exposed photographic film lets out said exposed film to an outside through a film outlet formed on said film take-up chamber, said processor comprising:
