Abstract
Abstract In a photographic camera which includes a chamber for receiving endwise, i.e. axially, a film cassette capable of automatically thrusting a non-protruding film leader to the exterior of the cassette shell responsive to unwinding rotation of a film spool within the shell, an ejecting member pops the film cassette at least part way out of the chamber end first when a cover door for the chamber is manually opened.
