ABSTRACT:
A document feeding device mounted on an image processing device such as a copying machine for automatically feeding duplex original documents having images to be read on both sides to an image reading point one by one in such a manner that the document fed from a supply tray is reversed at a switchback part, sent through the image reading point to read the image on one side thereof, sent back to the switchback part to be turned upside down, again sent through the image reading point to read the image on the other side thereof, and then, discharged to a discharge tray. The documents can be rationally transported at high speed with high efficiency, and consecutively discharged to the discharge tray in the same order of page as those initially set on the supply tray.
