Zusammenfassung:	The instant camera with a film cassette held in a compartment at the back has a film feed system with a hollow roller above the compartment. The roller rotates against a curved surface on a second roller to withdraw the next sheet vertically and eject it from a slot through the top of the casing. The roller is of metal or plastics and shaped to be sufficiently resilient to exert a suitable pressure to spread the material inside the film sheet. This resilience can be obtained by incorporating a slot across the roller during manufacture. Extraction of the next sheet is assisted by a vertically sliding member housed in a slot alongside the cassette compartment.
