An arrangement for unloading and loading X-ray film cassettes includes a frame-shaped support bounding a guiding channel in which there are received, one above the other, a plurality of mounting portions and, at the top, a cassette-handling unit. The mounting portions have identical configurations and bound respective channels of identical dimensions in each of the mounting portions. Storage receptacles of external dimensions compatible with those of the channels are respectively introduced into the latter. Each of the storage receptacles includes an insert selected from a plurality of inserts. Each of the inserts bounds a recess which is so dimensioned as to fittingly receive a stack of films of a given size. The recesses are so arranged that one corner of the recess is arranged at the same corner region of the insert in all of the inserts. The cassette-handling arrangement includes devices which open the cassette, withdraw the film therefrom, introduce a fresh film thereinto, and close the cassette. The films withdrawn from the cassette can be directly fed into a processing machine, or they may be forwarded into a storage container mounted on the cassette-handling unit. The mounting portions have aligned through passages at their associated ends, through which the films withdrawn from the storage receptacles are transported by transporting rollers toward the respective cassettes. A path-selecting element may be provided for bypassing the storage container.
