ABSTRACT:
In a document feeding apparatus, a document table carrying documents is provided with a stopper plate. The stopper plate can move between a stop position to retain the documents on the document table and a release position to allow the documents on the document table to move by the force of gravity. A first guide plate to guide the forward edges of the documents is provided on the lower-course side of the document table with respect to the document feeding direction. An obtuse angle is formed between the plane containing the first guide plate and the plane containing the document table. The forward edges of the documents transferred from the document table are guided by the first guide plate so that they are trued up in an oblique manner. On the document feeding side of the guide plate intake rollers are arranged which pick up and deliver, one by one, the documents guided by the guide plate in an orderly manner. The intake rollers are coupled to a first drive mechanism, and are rotated thereby in one direction to pick up the documents.
