A photographic film cartridge typically including a cartidge case having a longitudinal axis, opposite end walls and a film outlet for feeding the film out; a spool extending substantially coaxially with respect to the cartridge case and carried at the opposite end portions by the opposite end walls of the cartridge case for rotation about the longitudinal axis of the spool, the spool being capable of being rotated from outside of the cartridge case; a film wound into a roll on the spool with an end of the film connected with the spool; a slidable cover provided on the cartridge case for slidably moving along a surface of the cartridge case toward the direction inclined to the film feeding direction to slide toward the direction to open and shut the film outlet, and further including device for keeping the film tightly wound into a roll on the spool, whereby the tip end of the film can be fed out hrough the film outlet by rotating the spool in the direction opposite to the film winding direction.
