ABSTRACT:
There is described a document feeding apparatus and an image reading apparatus, which are employed for a copier, a facsimile, a scanner, etc. The document feeding apparatus or the image reading apparatus includes: a document feeding tray on which documents are stacked; a paper forwarding device to forward the documents; a document detector to detect the documents; and a controller to control the paper forwarding device. When forwarding a document having a length equal to or greater than a predetermined length in a conveying direction, the controller activates the paper forwarding device so as to forward a next document based on a detected result acquired by the document detector. While, when forwarding a document having a length smaller than the predetermined length, the controller activates the paper forwarding device so as to forward a next document without being based on a detected result acquired by the document detector.
