  • Patent number: 4258263
    Abstract: A cassette for releasably holding a photosensitive film unit and locating the film unit at a film plane therein. The cassette includes base and cover sections coupled together in telescoping relation for movement toward and away from each other between releasably latched first and second closed positions. In the first closed position there is minimal pressure applied to the film unit to facilitate its removal from the cassette. When the case and cover sections are located in the second closed position sufficient pressure is applied to the film unit to urge it into intimate contact with a film plane defining bearing surface in the base section. In the illustrated embodiment the cassette is configured for radiographic applications and includes an intensifying screen that is urged into intimate contact with the film unit when the base and cover sections are located in the second closed positions.

  • Patent number: 4249818
    Abstract: Photographic apparatus usable with a large format film processor for receiving and supporting a cassette holding an exposed film unit and for unlatching structure on the cassette to substantially reduce pressure on the film unit to facilitate its movement over a film bearing surface as the film unit is advanced from the cassette into the entry of the film processor. The cassette includes differently configured forward and rear pressure latch release members and the apparatus includes conforming forward and rear latch release actuators. The actuators are configured to allow the forward release member to pass by the rear actuator without causing premature actuation of the forward release member.
