Abstract

In order to prevent a storage film from being damaged when taking an X-ray image, when reading the latent X-ray image and when handling the storage film, the invention proposes providing spaced-apart guide parts on the rear face of the storage film, these guide parts not having an adverse effect on the ability of the film to bend. The guide parts interact with guide rails which are provide in a cassette which accommodates the storage film or on a film-clamping slide of a reader.
