In the present invention, provided are an LED substrate which is disposed above a long heat-radiating chassis, and a light source in which multiple LED elements are arrayed on the LED substrate in a straight line in the length direction. The light source is an integrated unit in which at least two light sources are provided together integrally. One light source illuminates the side at which a sorting object goes downstream, and the other light source illuminates a background side disposed facing a camera. |
