Abstract
An image reading apparatus further includes a discrimination unit which discriminates double feeding of a document from a carrier sheet, based on a double feeding detecting sensor (double feeding detecting unit) which detects double feeding of a document, a first detection result (section of L) which is obtained when the double feeding detecting sensor detects a bonding portion of the carrier sheet, and a second detection result (double feeding detection value which is lower than second threshold value) which is obtained when the double feeding detecting sensor detects double feeding.
