Abstract

A casing, particularly for roll film cartridges, includes a hollow housing having a chamber for closely receiving a film cartridge and a channel which communicates with the chamber. The channel is operative for receiving a length of roll film which extends out of the cartridge when the latter is inserted into the chamber. The channel extends tangentially to the chamber and has at least one flat inner surface along which the length of roll film can extend to be held in flat condition.
