ABSTRACT:
An automatic film unloading apparatus permits an undeveloped film to be automatically unloaded from its cartridge, rewound correctly in a case within a short period of time, and moved to a location where it is joined to a film leader. An intermediate film takeup cartridge for use in the automatic film developer apparatus includes an intermediate cartridge body including a film takeup roller and a base which can easily be separated from each other. When the entire length of an undeveloped film is rewound on the film takeup roller or the undeveloped film is jammed, the intermediate cartridge body is readily separated from the base, hence allowing the taken up or jammed undeveloped film to be removed from the film takeup roller with ease.
