Abstract: The invention relates to a film-processing apparatus, in particular for X-ray sheet film, with a first feeding device arranged in a daylight environment and serving for transporting film cassettes to a film loading and unloading station, a second feeding device arranged in a darkroom environment and serving for transporting exposed film, and with a transport device for moving the film sheets to a film-processing station, said apparatus being designed such that film can be fed to the film-processing station in a simple manner either in a daylight environment, in a darkroom environment or in both environments without the apparatus having to be modified in a complicated way. For this purpose, the apparatus comprises sealing means which connect the second feeding device with the darkroom in a light-tight manner and are releasably attachable by adhesive means, and the second feeding device can be closed in light-tight manner by means of a lid pivotally mounted on a housing of the film-processing apparatus.
