Abstract

PURPOSE:To enable to ensure the detecting of the information on the object to be read in independently of the color on the object to be read in, by providing illumination lamps, color separator, and a plurality of signal processing circuits and addition circuits. CONSTITUTION:When a mail P corresponds to the optical system 1, the light emit- ted from illumination lamps 2, 3 is radiated on the mail P. Further, the reflected light is fed to a color separator 8. In this case, when the mail P is printed in red or the like, the output of a signal processing circuit 50 is a signal without almost any change as shown in Fig. (a), and the output of a signal processing circuit 60 is a signal with greater change as shown in Fig. (b). Thus the output of the circuits 50, 60 is added 70 to constitute the signal corresponding to the video information on the mail P as shown in Fig. (c). If the mail P is printed in blue or green, the output of the circuit 50 is a signal with greater change and the output of the circuit 60 is a signal without almost any change, and the signal corresponding to the video information on the mail P can be obtained from the addition circuit 70.
