Abstract

Present commercial precollation copiers copiers, such as the "Xerox" "1075" or "1090" copiers, provide collated copy output for documents recirculated for copying by the RDH Irecirculating document handler), However, such "over-platen" or "racetrack" type RDH copiers copy the documents in their reverse page order with the RDH, i e., n to f This calls for face-= stacking of the copy sheets in the output tray to provide collated output.

AUTO-SWITCHING OF OUTPUT Proposed Classification INVERTER FOR NON-RDH INPUT
C1.355/14 S U Anonymous Int. C1, G03g 15/00

Present commercial precollation copiers copiers, such as the "Xerox" "1075" or "1090" copiers, provide collated copy output for documents recirculated for copying by the RDH Irecirculating document handler), However, such "over- platen" or "racetrack" type RDH copiers copy the documents in their reverse page order with the RDH, i e., n to f This calls for face-= stacking of the copy sheets in the output tray to provide collated output.

Collated output is also desirably automatically provided for documents which are single-copied manually on the platen of these copiers in their normal forward or f to n page order. When one copy at a time is made from documents other than in the RDH, the copies come out collated by automatic face-down stacking at the same two output trays, 1. e., without manual switch changing of the output inverter operation. The "1090" copier, which was publicly announced February 12, 1985, likewise also automatreally provides collated face-down output of copies from documents which are presented to the alternative SABH input of these copiers in 1 to n document page order This proper order output sheet stacking is provided automatically, and with no additional hardware or UMC The document presence IR sensor in the RDH document tray is already logrc connected in the copier controller A software change or addition automatically actuates the existing inverter gate in the copier paper path (For such an inverter gate, see, e g I 16 S. 4,278,344, ref
118) to invert or non-invert the copy sheets so that at either of the two output trays the copies will automatically be fed out to stack face-down whenever the copier is operated with no documents in the RDH tray, 1 e whenever copying

1s from the SADH input or from manual document copying on the platen, and the copier is also in a single copy mode As noted, this is the opposite of the inverter operation required for copying with the RDH

Expressed generically, this is an...
