画像読取り装置。 An image reading device comprising a white guide and a mirror for guiding reflected light from a document onto a line sensor via an imaging lens, the white guide, the mirror, the imaging lens, and the line sensor. The sensor is installed to extend outward from the effective optical path width used for reading the document image, and is placed between the axis in the optical path width direction of the mirror in the incident optical path and reflected optical path of the mirror in the extended area. An image reading device comprising at least a pair of optical path shielding plates.
