Abstract
A cassette holds sheets of film which form a positive image on one side thereof. The cassette is especially configured to minimize accidental discharge of the film sheets due to jars or impacts. A pick is used to penetrate a pick slot in the forward wall of the cassette to engage pockets formed on the leading ends of enclosed film units and urge them through an egress opening in the forward wall of the cassette. A probe opening in the rear wall of the cassette receives a probe from below to urge each film unit successively into alignment with the egress opening at the time the pick engages the pocket in each film sheet. Inward offsets at the leading end of the cassette are filled by two hold-back fingers, one on each side of the cassette, to engage hold-back shoulders on the leading end of each film sheet to prevent inadvertent discharge of the sheet due to impacts on the cassette.
