Photographic film package with detachable cartridge

摘要

A lens-fitted photographic film package (20) with dual lens (26) includes a film-free self-activating shutter mechanism (52) and a detachable cartridge (54) for removing and installing film. A 35-mm film cartridge (74) is attached to a cartridge adapter (78), and a filmstrip end (138) is inserted and pre-wound into a winding housing (82) including a winding spool (84) therein. As photographs are taken, film is advanced home-by-frame into the film cartridge, where it may be easily removed from the adapter without rewinding of the film, and replaced by a fresh film cartridge. Thus, the adapter transforms the lens-fitted photographic film package into a reusable package.
