ABSTRACT:
A box-shaped container for photographic film has an outer casing and a cover. When the cover is opened, an inner casing with a cylindrical film roll chamber can be removably inserted in the outer casing. After a trailing end of the developed photographic film is anchored to a core, the core is inserted in a lateral direction into the film roll chamber. Then, disks are fitted on both lateral ends of the core. When the inner casing is inserted into the outer casing, the core is supported rotatably by the outer casing. The developed photographic film is wound on the core completely in a roll. The disks serve to limit the diameter of the rolled developed photographic film, which enables rotation of the core to be transmitted to an outermost turn of the developed photographic film, whereby a leading end of the developed photographic film is advanced out of the outer casing through the inner casing.
