Abstract

A device for the automatic removal of a photographic film from a cartridge in which the film has been wound onto a spool. A guide opening for the cartridge has a cross-section which allows the receiving of the cartridge in only one orientation is provided so that the cartridge moves through the opening in the direction of its spool axis by its own weight. A system for simultaneously linearly displacing and rotating the axis of the spool is provided, to rotate the spool axis from vertical to horizontal and to reposition the cartridge for unwinding the film from the spool. The system holds the cartridge in a spool receptacle, and repositions and rotates the cartridge with a single actuator.
