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; said photographic film unit being preloaded with an unexposed photographic film, and including: a) an exposure station for exposing said unexposed film; b) a film supplying chamber disposed beside said exposure station for containing said unexposed film wound in a roll with a film leader wound internally; c) a film take-up chamber disposed on a side opposite to said films supplying chamber with respect to said exposure station, in which a spool is contained rotatably, on which spool said film subjected to exposure is wound after passage through an entrance of said film take-up chamber when said spool is rotated in a first direction; d) a shutter and a taking lens disposed in front of said exposure station; e) a film wind-up mechanism for rotating said spool so as to feed said film frame by frame; f) a film outlet formed on said film take-up chamber for passing said film leader toward an outside of said film unit when said spool is rotated in a second direction opposite to said first direction after winding said film leader in said film take-up chamber; and g) a light shielding member provided with said film outlet for shielding an inside of said film take-up chamber from light; and said processor including: A) film unit holding means for being loaded with said film unit; B) a processor unit for processing said exposed film; C) control means for controlling said processor unit; D) spool rotating means for rotating said spool in said film unit loaded in said film unit holding means in said second direction in accordance with an output from said control means; and E) film transporting means for transporting said film leader to said processor unit in accordance with an output from said control means, said film leader being let out of said film outlet.
