ABSTRACT:
A sheet original feeding apparatus comprises a sheet original stacking tray on which sheet originals to be treated are stacked as an original stack. A sheet original separator separates and supplies the sheet original one by one from the bottom of the original stack stacked on the sheet original stacking tray. A sheet original feeding path is provided for directing the sheet original separated by the sheet original separator. A sheet original feeder feeds in a forward direction the sheet original directed by the original feeding path to an image reading portion. The sheet original feeding means is also operable in a reverse direction, and the sheet original feeding path is arranged at one side of the sheet original feeder. A first sheet original ejecting path is further provided for returning the sheet original fed in the reverse direction by the sheet original feeder to the sheet original stacking tray from a same side of the sheet original feeder as the sheet original feeding path. A second sheet original ejecting path returns the sheet original fed in the forward direction by the sheet original feeder to the sheet original stacking tray. The second sheet original ejection path is arranged at a side opposite to the sheet original feeder means as the sheet original feeding path.
