Summary:PROBLEM TO BE SOLVED: To provide an image reader capable of reading a high-quality image regardless of the surface shape of a manuscript. SOLUTION: The image reader comprises a manuscript placement stand for placing the manuscript; at least one light source for emitting light to the manuscript from each of a plurality of light source positions that deviate from a position opposite to the manuscript on the manuscript placement stand and have mutually different elevation angles looked up from the manuscript; and an image reading section for receiving light obtained from the manuscript to which the light of the light source is emitted to read the image of the manuscript and for generating image data for indicating the image of the manuscript. The light source position is changed according to the surface shape of the manuscript, thus emitting the light of the light source at an irradiation angle suited for the manuscript, and hence reading the image of the manuscript, where the surface is rough and the irregular reflection of light is easily generated, with high quality.
