ABSTRACT:
Establishing a reading station for reading images on an document disposed in a transport path between paired transport rollers and paired discharge rollers to sequentially feed documents on a sheet supply tray enables a compact device and arranging a detection sensor that detects the trailing edge of an document to detect the discharge thereof to a discharge tray at a position on the discharge tray side from the pressing point of the paired discharge rollers, and the positioning of a detection sensor to detect the leading edge of an document to control the start of reading documents, at a position upstream of the transport roller prevents distortion of the document and enables the certain detection of documents.
