ABSTRACT:
A cassette for holding x-ray film and the like is disclosed. A cam hinge urges a cassette lid and a tray into a closed film holding position from which visible light is excluded. The lid and tray are pulled toward one another by magnetic attractors located around the lid and tray edges. A low-stress latch secures the lid and tray in their closed position. A light lock within the tray insures the exclusion of visible light from the cassette interior.
