Abstract
A drive mechanism is disclosed for a document feeder which is used in supplying documents to-be-copied onto the glass top of a copy machine. The drive mechanism includes a set of feed wheels which remove the document to-be-copied from a document support and by rotating in one direction move the document to-be-copied against a set of drive wheels. The drive wheels, when rotated in one direction, move the document onto the glass top of a document copier against a stop, where the document is copied. Thereupon the drive wheels rotate in the opposite direction to remove the copied document from the glass top of a copying machine and deposit the copied document into a receiving tray.
