Abstract:
1. An image reading apparatus comprising: a light source having a first luminescent portion that outputs a light with a first wavelength range and a second luminescent portion that outputs a light with a second wavelength range, the first wavelength range being different from the second wavelength range; a light-receiving portion that receives a reflection light reflected from an original irradiated by the light source; a scanning portion that shifts a reading position of the original read by the light-receiving portion in a vertical scanning direction, by changing a relative position between the original and the light-receiving portion; a switching portion that alternately turns on the first and second luminescent portions when the scanning portion shifts the reading position; a separation portion that separates data received by the light-receiving portion into a first data obtained when the first luminescent portion is turned on and a second data obtained when the second luminescent portion is turned on; an image information acquisition portion that acquires an image information based on the first data separated by the separation portion; and an identification information acquisition portion that acquires an identification information based on the second data separated by the separation portion.
