Abstract
A document feeding device for feeding documents to a document scanning section where the image of the document is scanned. The document feeding device has first trasnport rollers for feeding each document to the scanning section, discharge rollers for discharging from the scanning section the document thus supplied, a reversing transport path for passing and turning over the document sent from the discharge rollers, and second transport rollers for feeding the document that has been turned over through the reversing transport path to the document reading section. The reversing transport path is designed to change the length of the document transport path depending on the size of the document. With the arrangement, reversing operation and scanning operation of the documents can be performed effectively. Further, without increasing the momentary transporting speed of the document transport mechanism, this arrangement makes it possible to feed documents at comparatively high speed from an entire apparatus standpoint.
