A sheet reading device comprising a lens system and an image sensor that converts an image formed by the lens system into an electrical signal, wherein a light condensing plate is disposed between the light source and the sheet, The light condensing plate includes a slit of a predetermined width located in the longitudinal center of the optical path, non-reflective parts located on both sides of the slit in the longitudinal direction, and non-reflective parts located at both ends of the slit, the width of which increases sequentially from the inside to the outside end. A sheet reading device with a wide reflective section.
