ABSTRACT:
A camera comprises a film cartridge receiving chamber for receiving a film cartridge with a filmstrip having a film leader, a film passageway for the filmstrip, and a sprocket movable from outside to inside the film passageway to engage the filmstrip. A film slit is formed between the cartridge receiving chamber and the film passageway to permit the film leader to be longitudinally inserted through the film slit into the film passageway when the sprocket is outside the film passageway. A rear cover is located over the film passageway. A rear door independent of the rear cover is supported for closing to cover the cartridge receiving chamber and to move the sprocket from outside to inside the film passageway to engage the filmstrip, after the film leader is longitudinally inserted through the film slit into the film passageway.
