Documents to be copied are placed face up as a stack in a supply tray, and feed rollers carried by the tray are actuated to advance documents individually from the top of the stack to the inlet of the copier. A friction retarding roller engaging the bottom of the stack at the feed end is positively driven in a reverse direction to prevent the simultaneous feed of more than one document. From the inlet, the documents are fed to the imaging platen, and after copying into a receiving tray above the platen. In an alternative, semiautomatic mode, the supply tray is moved to an inoperative position and an original is manually inserted face up into the inlet. In an alternative embodiment, the feed roller is disposed below the retarding roller to feed sheets from the bottom of the stack so that the sheets are collected in the receiving tray in their original order. <IMAGE> |
