ABSTRACT:
A paper refeeding device incorporated in a copier for stacking one-sided paper sheets each carrying an image on one side thereof on an intermediate tray and then refeeding the paper sheets from the tray for forming an image on the other side thereof. In a two-sided copy mode operation, the device reduces the copying time while eliminating paper jam, missfeed and other troubles. The device stacks one-sided paper sheets stably on the intermediate tray and refeeds them without any skew. In addition, the device is simple in construction and implements automatic timing control.
