Abstract
An x-ray film cassette has a window for illuminating patient data and a slide movable over the window to shut out light. A counterpoise of ferromagnetic material is provided for locking the slide in a closed position and which can be released magnetically. The counterpoise is pivotably mounted about a tilt axis passing through its center of gravity. A spring member is provided for biasing the counterpoise such that an end face is positioned within the window to prevent movement of the slide.
