An arrangement for the infeed and outfeed of valuable documents from one opening of a plurality of openings to another opening of the plurality of openings com­prises command means operative to control the function of the arrangement from an external location, and stor­age means for the intermediate storage of valuable documents during their passage along a transport path between the openings. The storage means (131-141-20) has two mutually coacting belts (13, 14) which together form a common infedd-and-outfeed opening (15) for valuable documents transported sequentially in series. The storage means (131-141-20) is located in a pivotal housing (16) which is operative to positionally adjust the opening (15) of the storage means in relation to one opening of the plurality of openings in response to commands from the command means (34). This posi­tional adjustment can also be carried out independence on the sensing result of a sensing means (17) positioned adjacent the transport path in the proximity of the storage means (131-141-20).
