Here, images on both reverse and front surfaces of loaded paper can be automatically read out with one loading by the front or reverse of the loaded paper coming into contact with the surface of the platen roller rotated in a fixed direction so as to be moved in one direction, an image of the front or reverse of the paper being read out and, after the paper has been temporarily removed from the platen roller due to movement, the paper being returned in the opposite direction so that the front or reverse of the paper again comes into contact with the surface of the platen roller so as to be moved again in the one direction in such a manner that an image on the reverse or the front of the paper is read out.
