Abstract

The invention relates to an X-ray examination apparatus comprising a light-tight film processing section with one or more film storage magazines. A film sheet can be removed from the magazine in order to be transported to the exposure position. The apparatus also comprises a cassette loading and unloading station as well as a film guide device. A film sheet can be transported by the film guide device either into the beam path at the exposure position or into a cassette in the cassette loading and unloading station. Thus, cassette exposures can also be made without loading and unloading the cassette in a separate dark room or without a so-called daylight system being necessary.
