ABSTRACT:
A film cassette is constructed from several cassette components which, when assembled, collectively comprise a film spool, a tubular-like casing substantially surrounding the film spool and having a pair of spaced lips which define a film passage slit from the spool, and a pair of end caps covering respective open ends of the casing. The end caps are connected by an integral bridge or spout portion which completely encloses the two lips and includes a film passage opening to the film passage slit. This arrangement provides a relative secure assembled cassette.
