Abstract

The image reading device of the present disclosure includes a transport section a read section 5 that reads an image on the medium; a control section 6 that processes the read image 14 and that controls transport of the medium, wherein the control section performs an abnormality determination process on the abnormality determination region 13, which is set for the leading edge region of the read image of the medium. The abnormality determination process includes a first step that involves processing the pixels of the read data contained in the abnormality determination region into a state that allows distinction between pixels in an intra-medium region 20 and pixels in an extra-medium region 21, a second step that acquires the maximum distance WL from the center position in the medium width direction to the one edge 24, and the maximum distance WR to the other edge 25, and a third step that determines whether an abnormality exists in the transport state based on each of the maximum distances.
