Abstract

PURPOSE: To detect reddish or greenish color of banknotes by combining comparators or the like to two kinds of light emitting diodes.
CONSTITUTION: Red color and green color diodes 6, 5 are connected to switching circuit 2 to which sine wave oscillation output of oscillator circuit 1 is fed. A comparator 18 is connected to a photo detector 7, which is opposing to the both diodes 6, 5 by way of alternating current amplifier 9, detector circuit 10, and amplifiers 16, 17. In this constitution, when a banknote is inserted between the diodes 5, 6 and the photo detector 7, if the color of the banknote is neither reddish nor greenish, the output of the detector circuit 10 is zero level and output signal is not delivered from the comparator 18; if the color of the banknote is either reddish or greenish, the output of the detector circuit 10 shows a positive or negative value, which is compared with the reference level at the comparator 18, and an error signal is delivered from an output terminal 20.
