Abstract

A film cassette, particularly an X-ray film cassette, includes a housing which bounds a compartment for accommodating a film and having an opening for exposing an image on a predetermined portion of the film in the compartment. The opening is light-tightly closed by a closure which is displaceable between its closed and open positions and which is latched in its closed position by a latching member which is pivotally mounted on the closure and engages the housing at one of its ends. The other end of the rocker is accessible to an actuating pin of an exposing device through an access opening in the closure, so that the actuating pin can pivot the rocker into its releasing position in which the closure is free to move towards its open position, and displace the closure between its closed an open positions. When the closure is open, the exposing device exposes data onto a portion of the film in the cassette which is aligned with the opening.
