ABSTRACT:
An apparatus and method for detaching and reattaching a filmstrip from a film cartridge. The film cartridge includes a spool rotatably mounted therein around which is wound a photosensitive filmstrip and an opening through which the filmstrip may pass for allowing the filmstrip to be removed from or returned to the film cartridge. The filmstrip has a leading edge and a trailing edge, the trailing edge of the filmstrip being detachably secured to the spool. The mechanism comprising a holder for holding the cartridge in a predetermined axial position; a guide for providing a single film guide path along which the filmstrip is guided when the filmstrip is being removed from or being returned to the film cartridge; a detach tool movable along a first tool path such that the tool can be inserted into the film cartridge such that the trailing edge of the filmstrip may be detached from the spool; and a reattach tool movable along a second tool path different from the first path so as to allow the tool to engage the trailing edge of a filmstrip being returned to the film cartridge along the second guide path. The detach tool, reattach tool, and guide are in axial alignment with respect to the filmstrip disposed in the cartridge.
