In a picture reading device having a light emitting element that obliquely irradiates the surface of a paper with light, an area sensor that reads its irradiated area as a picture in which information related to a paper is read on the basis of the read results, the light irradiating element is arranged with an angle so as to irradiate the light from a direction oblique to a conveying direction of the paper. As a result, the picture reading device of the present invention eliminates such a problem that the same paper surface is received as a different image depending on the incident direction of the light, and the information related to an object to be read cannot be accurately read.
