摘要： This invention involves a film cassette for resiliently holding a film unit for exposure. The cassette includes a forward wall, a rear wall, two side walls, a leading end wall and a trailing end wall all combined to form an enclosure for holding the film unit. An exposure opening in the forward wall allows exposure of the film unit and an egress opening in the leading end wall allows it to be discharged after exposure. A pick slot in the forward wall provides access to a pick to engage the film unit and advance it through the egress opening. A spring platen mounted within the chamber between the rear wall and the film unit biases the film unit against the forward wall in proper position for exposure through the exposure opening.
