Abstract
Abstract Sheet handling device useful for handling sheets to be processed by data processing apparatus, such as a ledger accounting machine. The device includes a main hopper compartment into which documents to be processed are manually deposited, an auxiliary hopper compartment for blank documents, a main stacker compartment into which processed documents are automatically advanced, a stacker ram in the main stacker compartment to compact documents as they are stacked, an auxiliary stacker compartment for accumulating completely filled processed documents for subsequent manual removal, and a document hold station for temporarily storing partially processed documents pending the generation of data to be recorded in summary thereon. Feed rollers are provided for selectively feeding documents to be processed and blank documents from the main and auxiliary hopper compartments, respectively, to the processing station of the accounting machine, for selectively advancing partially processed documents from the processing station to the document hold station, for recallably feeding partially processed documents from the document hold station to the processing station to complete the processing thereof, and for selectively feeding fully processed documents and filled documents to the main stacker compartment and the auxiliary stacker compartment, respectively.
