摘要： In a printed matter identifying apparatus of the present invention, the light source (2) illuminates the detecting fields (3, 3') of the note (1). The reflected light-waves from the detecting fields (3, 3') are lead to the light receivers (10, 11, 10', 11') through the focusing lenses (4, 4'), the diffusion plates (5, 5'), the optical slits (6, 6'), the light conducting paths (7, 7') and red color transmitting and blue color transmitting filters (8, 9, 8', 9'). The output signals from the light receivers (10, 11, 10', 11') are amplified by the amplifiers (12, 13, 12', 13') and sampled by the sampling circuits (14,15,16,17). Among the sampled color component signals, the red component signals are applied to the subtracter (20) to produce the red component difference signal and the blue component signals are applied to the adder (21) to produce the blue component sum signal. These different signal and sum signal are applied to the comparators (27, 28) respectively and compared with the reference signals read out from the memory (24). The output signals from the comparators (27, 28) are supplied to the judgment circuit (29) where the judgement of the printed matter is performed.
