ABSTRACT:
A developed photographic film is contained in a cartridge such that the leader end of the photographic film does not protrude from the cartridge, the film being wound on a spool. In one embodiment, the cartridge has a notch formed in the side of a port portion. The photographic film is pushed out of the cartridge by a sprocket accessed to this notch when extra prints are made. In another embodiment, two roll chambers are connected with each other through a bridge portion having an aperture for exposing a picture frame. A further embodiment includes a splice tape connected at one end to the spool, the photographic film being connected to the spool through this splice tape. These respective embodiments can also be used as a container for containing an unexposed photographic film.
