An x-ray film cassette (10) having a base (14) and a cover (16) adapted to close upon the base (14). The cover (16) is provided with an identification window (68). A pressure plate (64) is secured within the cassette (10). The cover (16), pressure plate (64) and base (14) form a light-tight space for receiving a sheet of x-ray film. The pressure plate (64) is also provided with an identification window (66) which is in substantial alignment with the identification window (68) of the cover (16). A light-tight slideable window shutter (70) is provided for covering of the identification window (68) of the cover (16) and/or the pressure plate (64). The slideable window shutter (70), when in a first position, provides a light-tight seal against the windows (66,68) and when in a second position allows information to be provided to an x-ray film contained within the cassette (10). An indicator assembly is secured to the pressure plate (64) and is at least partially visible through the cover (16) for indicating when film is present within the cassette (10) and for indicating when the window shutter (70) has been opened.
