Abstract
An X-ray film cassette with a lid which is pivotable with respect to a bottom. Between the lid and the bottom is an X-ray film which bears on a pivotable film pressure plate. The film is retained clear of the bottom and the lid by means of springs which bear against the bottom as well as against the lid. The X-ray film has an edge region which projects from the film pressure plate so that it can be engaged by transport rollers. In the X-ray film cassette according to the invention, sticking of the X-ray film is avoided.
