An X-ray cassette which is loaded with film and unloaded automatically by cassette-handling apparatus. The cassette comprises an exterior case having an opening to receive actuating means from the casette-handling apparatus, film-carrying panels within the exterior case adapted to hold film while it is radiographically exposed, and control means operatively connected to the film-carrying panels and adapted to be engaged by the actuating means from the casette-handling apparatus. The control means applies the movement of the actuating means to the film-carrying panels to move the panels between film-exposure and film-load-unload positions. In one embodiment the actuating means is a pin that undergoes forward and return movements and the control means includes a slide member and a control lever pivotably mounted on the slide member, both the slide member and the control lever being apertured to receive the actuating pin. During film-exposure, a portion of the control lever engages a lock member within the cassette to lock the slide member, control lever and film-carrying panels in their film-exposure positions.
