<P>PROBLEM TO BE SOLVED: To provide an image reading device which can arrange a light source lamp to be arranged at a position close and opposite to an image reading surface, and a reflection mirror at positions very close to each other, and can read out a shiny image in strict quality. <P>SOLUTION: In an image reading device, a first light source having a predetermined incident angle to a reading surface and a second light source having a smaller incident angle than the predetermined incident angle are arranged, and reflection light from the reading surface is photoelectrically converted by a common reading light path. One of a plurality of reflection mirrors disposed in the reading light path at this time, comprises a coating surface for performing mirror reflection of light to a surface of a translucent plate material and a non-coating surface through which light penetrates, and from a back side of the non-coating surface, light of the second light source is radiated to the reading surface. At the same time, an irradiation angle of light from the second light source and an angle of the reading light path are substantially set in the same angle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
