Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image reading device which reads a fed document image. SOLUTION: The image reading device 1 feeds a document G on a document feeding surface 2a of a contact member 2 by a front feeding roller 4, a front driven roller 5, a rear feeding roller 9, and a rear driven roller 10, makes the fed document G closely contact with the document feeding surface 2a by an aspiration operation by an aspirating fan through aspirating holes 20a and 20b formed at the contact member 2 and an aspirating tank arranged at a bottom of the contact member 2 when the document is read by an image sensor unit 3 while setting the vicinity of the document feeding surface 2a as a reading position Pa, enables a white reference board 8 to be shifted to the reading position Pa and a safe position separated from the document feeding surface 2a of the contact member 2, and shifts the white reference board 8 to the safe position at least while the document G is fed on the reading position Pa.
