ABSTRACT:
A sheet-feeding device for feeding individual sheets to the platen of a printing apparatus from a single storage unit or a plurality of storage units is provided. The sheet-feeding device incorporates a selecting disc incorporating a switching arrangement for the purpose of establishing a driving connection with the associated printing apparatus to a separating roller for withdrawing a sheet from the selected storage unit. In the storage units which have not been selected, the switching disc prevents inadvertent activation of the non-selected storage units by a blocking device controlled by a counter which permits the switching arrangement to be blocked during the printing process in order to prevent undesired sheet feeding.
