Abstract
A recirculating document handling apparatus for use in a copying machine having an exposure station at which a document to be copied is scanned. The RDH apparatus comprises a document support tray for accommodating a stack of documents to be copied, a recirculating transport mechanism for transporting each of the documents from the document support tray towards the exposure station and then from the exposure station back to the document support tray, and an auxiliary roller provided in the document support tray for feeding each of the documents towards a document feed unit. The auxiliary roller can be selectively operated at two different speeds to assist returning documents to the document feed unit.
