Abstract
A cover latch mechanism is disclosed for a photographic cassette, such as an x-ray film sheet cassette. Such cassettes typically have side walls, end walls and opposing front and rear cover walls in which one of the cover walls is rigidly secured to the end walls and side walls. The other cover wall is slidably moved along grooves in the side walls from a normally closed position to an open position for allowing easy access to the inside of the cassette for cleaning and maintenance. A latch mechanism is disclosed for releasably latching the other cover wall in its normally closed position.
