A device for storing and dispensing sheetlike materials comprises a coilable web (23) transferrable from one reel (20) onto another (22) and vice versa. For the storing of the sheets (24), the latter are introduced between adjacent convolutions of the web during the winding-up cycle. Dispensing of the sheets occurs by unwinding the previously coiled web (23) so that the sheets (24) are released again. The web (23) is driven by a rotating feeding roller (21). Via a slip clutch (28, 29) mounted on the reel driving shafts (20, 22), the web (23) is kept tensioned. As such, the problems of prior art systems, which make use of directly driven reels and which require a controlling of the coil diameter in order to store and dispense sheets at a uniform speed and tension, are avoided. The system is mounted in a light tight housing (11) and forms part of an X-ray daylight system in which it is used as intermediate magazine for unloading radigraphic cassettes.
