ABSTRACT:
A film cassette is disclosed wherein a filmstrip beginning with a relatively short non-protruding leader portion can be advanced automatically to the exterior of the cassette responsive to rotation of a film spool in a film unwinding direction. The filmstrip has one metering perforation per film frame in a relatively long imaging portion and several much closer spaced take-up perforations in its leader portion. Preferably, the take-up perforations are located along a different longitudinal edge of the filmstrip than the metering perforations are located, to positively prevent the possiblity of mistaking one of the take-up perforations for one of the metering perforations in a camera.
