装置。 First and second light sources for color discrimination, means for sequentially irradiating light from each light source onto the same spot on the document surface, and means for individually detecting the light from each light source irradiated onto the document surface. and means for determining color based on the presence or absence of light from each light source detected by the detection means, and when the detection signal of the light from the light source that illuminated the document surface first is zero, the light from the other light source is detected. An image reading device comprising a data processing circuit that stops scanning and feeds a document by one line.
