Abstract

PURPOSE:To increase the degree of accuracy in sorting by quality by applying a green ink having large absorptivity of white rays to defective products. CONSTITUTION:Facing to green ink 2 on a defective element 1, a light source 3 and a light-receiving means 4 are provided. The light source 3 irradiates white rays. The high-sensitive region of the light-receiving means is selected to be a wavelength band having large absorptivity of specially the white rays from the green ink. By said constitution, from the change in the qnantity of the light received by the light- receiving means 4, sorting by quality can be effected with high accuracy.
