ABSTRACT:
A film sheet cassette accommodates optical imaging by holding the edges of a film sheet between an apertured frame and a pressure plate. A cam arrangement permits the film to be released for loading and unloading through an end slot. The frame defines guide tracks for a slide plate that covers the aperture and prevents light access to the film when not in use.
