Abstract
Abstract A film sheet storage cassette. A channel mounting bracket supports a rectangular enclosure in position to receive cut film sheets. The enclosure includes a top flange which is slidable into the channel and held in position to receive through an entrance slot the paper film sheets. A spring biased door is supported for movement in the plane of the flange to cover and uncover said slot. The channel includes camming slots which receive upstanding camming tabs. Insertion of the cassette flange into said channel forces said camming tabs along said camming slots moving the door to its open position.
