An image reader has a transport passage for transporting an original, a CIS for reading an image on the original transported on the transport passage, and a control member for pressing the transported original against an abutment member disposed at an opposed side of the transport passage at a read position of the CIS. The original does not slide on glass at the read position of the CIS and is moved with the original abutted against the abutment member of a chute on the opposed side, and image data is read in sequence.
