ABSTRACT:
A photographic film is connected with a leader by engagement with an engaging piece provided on the leader. The film is then conveyed by being pulled by the leader since engaging holes in the film are engageable with engaging pieces provided on a leader. The engaging holes are formed at a leading end portion of a photographic film. Portions of the photographic film around the engaging holes are reinforced by adhering a reinforcement piece to the leading end portion of the photographic film, thereby preventing the photographic film from being torn at the engaging holes.
