ABSTRACT:
A convenience copier having duplex capabilities includes a collating feeder that inverts the document automatically for copying both sides thereof. The copier includes a processing section for establishing visible representations of the document, feeding sections for presenting document and copy sheets to the processing section on a one-document-sheet one-copy-sheet basis, and inverting means for presenting both sides of the document sheets for copying and both sides of the copy sheets for receiving the visible representations. The document feeding section circulates and recirculates the document sheets from a supply to an exposure position and back to the supply, and inverts the document sheets during such circulation and recirculation in a manner suitable for making collated copies without disturbing the sequence of the document.
