ABSTRACT:
A document feeding apparatus having both an automatic and manual feed mode. the apparatus includes a paper feeding belt for feeding documents from a stack set on a document stacker, wherein the lowermost document in the stack is fed, and a stop roller placed in contact with an upper surface of the paper feeding belt to prevent the overlapped feed of documents. Documents are fed through a common paper path in both modes. The belt and roller are commonly used in both the automatic and manual document feed modes. In the automatic document feed mode, the belt is driven while the roller is held in a non-rotational state. In the manual document feed mode, the belt is driven and the roller is driven by the belt.
