Discriminating system of genuineness of banknotes
专利汇可以提供Discriminating system of genuineness of banknotes专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a fixed banknote read pattern even when the voltage of a detector has dropped and achieve the improvement in the rate of acceptance of banknotes by using the output level of the time when the detector is an idle state as a reference.
CONSTITUTION: A banknote 1 is conveyed at a fixed speed. The quantity of light from a light source 3 is detected in a photoelectric element 2 after the transmission through the banknote 1, whereby the discrimination pattern of the banknote is read. While the photoelectric element 2 is in standby, the level of its output signal is passed through a gate 9 by the signal from a control circuit 6 and is stored in a B register 10 so as to be used as a reference level for correcting the read signal. The banknote read pattern having been stored 8 is corrected by the reference level and the corrected pattern and a model pattern are subjected to error judgement 14. At the coincidence ratios (above 80%) thereof, the identification of the genuine banknote is accomplished.
