Abstract
A method of accommodating a roll of photographic film in a main body of a photographic-film cartridge in which the cartridge is in a state in which one end of an elongated leader member is brought into engagement with a spool in the cartridge and a predetermined length of the other end thereof extends out of the cartridge includes a first step of inserting the leading end of a roll of photographic film into the main body of the cartridge, a second step of rotating the spool and feeding the roll of photographic film into the main body of the cartridge so as to wind the leader member and the leading end of the photographic film onto the spool, and a third step of rotating the spool so as to wind the rest of the roll of photographic film onto the spool, thereby accommodating the photographic film thus wound in the main body of the cartridge. A developed photographic film can be easily accommodated in the cartridge by making use of the frictional force produced by winding the leader member and the roll of photographic film together on the spool.
