  • Feeder for feeding and re-feeding an image forming apparatus
    Patent number: 7587166
    Abstract: A feeder includes a feed unit and a re-feed unit. A feed unit feeds a recording medium (such as a sheet of paper) on a feed tray to a printer engine. A re-feed unit feeds the recording medium having passed through the printer engine again to the printer engine. A roller pair for paper feeding and another roller pair for paper re-feeding share one drive roller. That is, the drive roller and a driven roller constitute the former roller pair, whereas the drive roller and another driven roller constitute the latter roller pair, thereby enabling the downsizing of the feeder.
