ABSTRACT:
An x-ray film cassette is disclosed which includes a window for allowing imaging of patient identification data onto a film in the cassette by light. The window includes a slidable member made from a single piece of plastics material folded onto itself to form two leaves. The two leaves are secured to one another except in a region adjacent the free end of one of the leaves. One of the leaves is stiff and the other is resiliently flexible. The stiff leaf faces outwardly of the cassette and has an aperture in a region overlying the unsecured region to the flexible leaf to allow a probe to deflect the unsecured region of the flexible leaf. The free end of the flexible leaf has catch means which cooperate with other catch means to prevent movement of the slidable member away from the closed position when the free end region of the second leaf is in the non-deflected condition. The catch means and the other catch means are disengaged from one another when the free end region of the flexible leaf has been deflected by a probe, thereby allowing the slidable member to move to the open position.
