Abstract

Abstract STATION AUTOMATICALLY IF ANOTHER COPY OF THE DOCUMENT IS TO BE MADE. THE SUCCEEDING PAGES ARE THEN FED IN (NUMERICAL) ORDER TO THE COPYING STATION AND THE SECOND COPY OF THE DOCUMENT IS MADE BY THE COPYING MACHINE. THE OPERATION IS CONTINUED UNTIL THE SELECTED NUMBER OF COPIES OF THE DOCUMENT HAVE BEEN MADE AND THE FEEDER IS SHUT OFF. THE COPIES ARE DELIVERED FROM THE COPYING MACHINE IN (NUMERICAL) ORDER SINCE THE DOCUMENT PAGES ARE ALWAYS MAINTAINED IN THE ORDER IN WHICH THEY ARE LOADED INTO THE FEEDER AND CONSEQUENTLY DO NOT HAVE TO BE COLLATED. A DOCUMENT FEEDER FOR USE WITH KNOWN COPYING MACHINES IN WHICH (THE) A DOCUMENT TO BE COPIED IS POSITIONED AT A COPYING STATION FOR EXPOSURE TO THE COPYING MECHANICH OF THE MACHINE. THE FEEDER ADVANCES A DOCUMENT PAGE FROM A DOCUMENT SUPPLY STATION TO THE COPYING STATION, POSITIONS THE DOCUMENT PAGE PROPERLY THEREAT, AND ACTUATES THE COPYING MACHINE TO COPY THE DOCUMENT PAGE. AFTER THE DOCUMENT PAGE HAS BEEN EXPOSED TO THE COPYING MACHINE, IT IS FED TO A DOCUMENT SUPPLY STATION. THE OPERATION IS REPEATED UNTIL ALL PAGES OF THE DOCUMENT HAVE BEEN COPIED. CERTAIN OF THE FEEDER EMBODIMENTS PROVIDE FOR AUTOMATICALLY FEEDING A DOCUMENT A PRESELECTED NUMBER OF TIMES TO THE COPYING MACHINE TO MAKE THE PRESELECTED NUMBER OF COPIES OF THE DOCUMENT. THE FEEDER AUTOMATICALLY COMPENSATES FOR ADVANCING DIFFERENT SIZE AND THICKNESS OF SHEETS SO THE INDIVIDUAL SHEETS OF A DOCUMENT STACK TO BE FED MAY INCLUDE SHEETS OF WIDELY DIFFEING SIZE AND THICKNESS. THE PAGES OF THE DOCUMENT STACK ARE FED IN (NUMERICAL) SEQUENTIAL ORDER TO THE COPYING STATION AND ARE STACKED AFTER EXPOSURE IN THE SAME (NUMERICAL) ORDER. AFTER THE LAST PAGE OF THE DOCUMENT IS REMOVED FROM THE COPYING STATION, THE FEEDER AGAIN ADVANCES THE FIRST PAGE OF THE DOCUMENT TO THE COPYING
