Abstract: An image reading apparatus controls a sheet feeding unit such that in a reading job in which a plurality of documents on a document tray is continuously fed, continuous feeding of the documents is stopped in response to changing of a detection state in which a document is detected on the document tray to a non-detection state in which no document is detected on the document tray. The control unit executes a first mode in which the sheet feeding unit stops the continuous feeding of the documents in a case where the number of documents having been discharged continuously in the reading job has reached a predetermined number of sheets, regardless of a detection result of the detection unit, and a second mode which continues the continuous feeding of the documents regardless of the number of documents having been discharged continuously.

Abstract: Provided is a sheet conveying device capable of suppressing the recurrence of overlapped feeding in accordance with the detection of overlapped feeding. The sheet conveying device includes a paper-supply roller and a conveying roller. A sheet-detecting unit detects a leading edge position of a sheet. An overlapped-feeding-detecting unit detects overlapped-feeding of sheets.

The conveyance-control unit, in a case where detection of overlapped feeding by the overlapped-feeding-detecting unit occurs a plurality of times, extends the set length based on the overlapped-feeding distance.
