ABSTRACT:
A method of prewinding film from a film cartridge having a rotatable spool for allowing a contained film to be thrust from the confines of the cartridge after a light blocking door is opened to permit a filmstrip to be thrust from the cartridge, into a film roll chamber using a roller assembly disposed between the cartridge and a film roll carrier to draw film from the cartridge after the leader portion has been thrust from the cartridge. According to the invention, the film roll carrier is detachable to allow the film cartridge and film roll carrier to be loaded into a camera body section after film has been prewound from the cartridge. Alternately, the prewinding can be done using a single roller assembly which interfaces with the film rails of a camera body to permit prewinding between a cartridge and the film roll chamber of the camera body.
