An image reading apparatus includes an image sensor fixed to a main body of the image reading apparatus, a light scanning carriage, a light reflection carriage, a pair of transport modules to move the light scanning carriage and the light reflection carriage in a sub-scanning direction with a predetermined speed ratio, and a wire having both ends fixed to the main body of the image reading apparatus and a portion fixed to the light scanning carriage, the wire wound around carriage pulleys of the light reflection carriage and fixing pulleys of the main body. Therefore, an accuracy of a moving of the carriages is improved, thus preventing a defective reading operation. Manufacturing costs of the image reading apparatus are reduced.
