ABSTRACT:
A film cartridge for use in cameras wherein a precise length of film is automatically fed across the shutter opening. The cartridge comprises a housing having a generally flat elongated portion and a generally cylindrical portion at one end of the flat portion. Inside the cylindrical portion are a film feed spool and a film take-up spool arranged in side-by-side relationship with driving means between them so that rotation of one spool automatically causes rotation of the other spool. At the other end of the flat portion is a roller arranged to cooperate with means for driving the film so that the film is pulled off of the feed spool causing that spool and the take-up spool to be driven. The take-up spool thus pulls the film and onto the take-up spool.
