ABSTRACT:
A recirculation-type document feeding device for a copying machine having a function of allowing a copied document to be alternatively discharged to a discharge tray or returned to a document tray. In a case of copying several times, the documents stacked on the document tray are transferred one by one to a document setting portion on a platen to be copied, and then, sent back to the document tray through a return passage. After copying completely, the copied documents may be eliminated to the discharge tray.
