Abstract: 지폐의 광학적 혹은 자기적 패턴을 검출하여 상기 지폐의 진위를 판별하는 지폐판별장치에 있어서, 상기 지폐에서 그 광학적 혹은 자기적 자기적 패턴을 검출하여 검출신호를 송신하는 검출수단과, 소정의 제1의 기준치를 아날로그 신호로 하여 출력하는 기준패턴 발생수단과 이 기준패턴 발생수단에서 출력된 소정의 제1기준치와 상기 검출수단에서의 검출신호와의 차를 출력하는 인산수단과, 이 인산수단의 출력신호의 직류성분을 제거하는 변환수단과, 이 변환수단의 출력을 본래로 얻어지는 신호를 소정의 제2기준치와 비교하여 그의 비교결과를 출력하는 비교수단과 이 비교수단에서의 출력에 의거하여 상기 지폐의 진위를 판별하는 판별수단과를 구비한 것을 특징으로 하는 지폐판별장치.
