It relates to a counterfeit bill discrimination apparatus used.

종래 동전교환기나 자동판매기 등에 설치되어 지폐의 진위 여부를 감별하는 위조지폐 감별장치는 내부의 기판상에 최소 길이 120mm, 직경 20mm의 자외선 조사 형광램프로 된 발광부와, 자외선 센서로 된 수광부로 구성되어 있어, 발광부로부터 발광되는 자외선을 지폐에 조사하여 지폐에 인쇄되어 있는 형광물질에 의해 반사되는 반사광을 수광부가 감지하고 이를 측정하여 광량에 의해 형광물질이 인쇄되어 있지 않은 위조지폐를 감별해 낼 수 있도록 하였다.Conventionally, counterfeit money discrimination device installed in coin exchanger or vending machine to discriminate the authenticity of banknote is composed of light emitting part of UV irradiation fluorescent lamp with minimum length of 120mm and diameter of 20mm on the inside substrate and light receiving part of UV sensor. The light-receiving unit detects the reflected light reflected by the fluorescent material printed on the banknote by irradiating ultraviolet light emitted from the light-emitting unit and measures it to discriminate counterfeit money not printed with the fluorescent substance by the amount of light. To make it possible.

그러나 상기와 같은 구성의 종래 위조지폐 감별장치에 의한 위조지폐 감별방법은 근래에 들어 급속하게 발전하는 형광물질의 인쇄기술에 의해 진폐여부를 가려내는 정확도가 떨어질 뿐만 아니라, 발광부의 크기가 커서 지폐 감별장치를 소형화하기가 불가능하고, 비교적 고가의 자외선 센서를 설치함으로서 제작비가 상승하게 되는 문제점이 있었다.However, the counterfeit money discrimination method by the conventional counterfeit money discrimination apparatus of the above-described configuration has not only reduced the accuracy of screening out the puffiness by the printing technology of the rapidly developing fluorescent material in recent years, and the size of the light emitting part to discriminate the bills.

지폐 감별장치로 지폐가 투입되면 자외선을 발광하는 소형 자외선 발광램프(2)로 구성된 발광부와;A light emitting unit comprising a small ultraviolet light emitting lamp 2 which emits ultraviolet light when the paper money is input into the paper money discrimination device;

발광부로부터 발광된 자외선이 통과하는 기판(1)(1')상의 투과공(4)과;A transmission hole 4 on the substrate 1, 1 'through which ultraviolet light emitted from the light emitting portion passes;

자외선 발광램프(2)로부터 방사되어 지폐를 통과한 자외선을 감지하는 청색컬러센서(3)로 구성된 수광부와;A light-receiving unit composed of a blue color sensor 3 for detecting ultraviolet light emitted from the ultraviolet light-emitting lamp 2 and passing through the banknote;

수광부로부터 출력된 광량을 기저장된 진폐 데이터와 비교하여 진폐 여부를 판정하고 그 결과를 표시부와 통신부에 전송하여 결과를 디스플레이하고 지폐를 통과 또는 반환시키는 제어부로 구성한 것이다.The amount of light output from the light receiving unit is compared with the previously stored pneumatic data to determine whether it is pneumatic, and the result is transmitted to the display unit and the communication unit to display the result and pass or return the bill.

이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

본 발명의 위조지폐 감별장치를 사용하여 지폐를 감별시에는 감별장치에 전원을 인가하여 소형 자외선 발광램프(2)와 청색컬러센서(3)를 작동시킨다(S10).When the banknote is discriminated using the counterfeit bill discrimination apparatus of the present invention, power is supplied to the discrimination apparatus to operate the small ultraviolet light emitting lamp 2 and the blue color sensor 3 (S10).

감별장치 외부 케이스(도면에는 도시하지 않음)의 투입구(도면에는 도시하지 않음)를 통해 지폐를 투입하여 도 3 의 도시와 같이 지폐(7)가 기판(1)(1')사이의 지폐 투입부(5)와 지폐 인출부(6)를 통과하는 동시에 자외선 발광램프(2)로부터 방사되는 자외선이 기판(1)(1')상의 투과공(4)을 통해 지폐(7)에 방사되고, 지폐(7)를 투과한 자외선을 청색컬러센서(3)가 감지하여 제어부에 신호를 송출한다.(S20).Banknotes are inserted into the banknotes 7 between the substrates 1 and 1 'as shown in FIG. 3 by inserting the banknotes through a slot (not shown) of a discriminating device outer case (not shown). Ultraviolet rays emitted from the ultraviolet light emitting lamp 2 at the same time as passing through the billing portion 6 and the bill taking part 6 are emitted to the bill 7 through the through hole 4 on the substrate 1 and 1 ', The blue color sensor 3 detects the ultraviolet rays transmitted through the 7 and transmits a signal to the control unit (S20).

청색컬러센서(3)로부터 자외선의 광량을 인지한 제어부는 이를 기 설정된 진폐 데이터의 설정값과 비교한다(S30).The controller, which recognizes the amount of ultraviolet light from the blue color sensor 3, compares the detected amount of ultraviolet light with a preset value of the pneumoconstrictive data (S30).

청색컬러센서(3)에 수광된 자외선의 광량과 진폐데이터의 설정광량을 비교하여(S40) 수광된 자외선의 광량이 설정광량보다 클 경우에는 기타 다른 항목을 검출하여(S50) 지폐 인출부(6)를 통해 배출한 후 또다른 지폐의 투입을 요구하는 신호를 출력시키고,The amount of ultraviolet light received by the blue color sensor 3 is compared with the set light amount of the pneumatic data (S40). If the amount of received ultraviolet light is larger than the set light amount, other items are detected (S50). After discharging through) outputs a signal requesting the input of another bill,

수광된 광량이 설정광량보다 작을 때에는 지폐(7)를 지폐 투입부(5)를 통해 다시 반출시키는 신호를 출력시켜(S70) 위폐를 가려내는 것이다.When the amount of received light is smaller than the set amount of light, a signal for transporting the banknote 7 back through the banknote input unit 5 is output (S70) to screen out forgery.

상기와 같은 작용에 의해 위폐의 감별이 가능한 것은, 진폐에 사용되는 용지는 자외선을 투과시키고, 위폐에 사용되는 용지는 자외선을 반사시키는 특성을 갖고 있기 때문에 진폐는 자외선 발광램프(2)로부터 방사되는 자외선을 대부분 투과시켜 진폐 데이터에 설정되어 있는 설정광량보다 많은 량의 자외선을 청색컬러센서(3)가 수광하게 되고, 위조지폐는 자외선 발광램프(3)로부터 발광된 자외선을 대부분 다시 반사시켜 청색컬러센서(3)에 수광되는 자외선의 량이 진폐데이터에 설정된 광량보다 작아지게 되는 것이다.It is possible to distinguish the counterfeit by the above-described action, because the paper used for the pneumonitis transmits ultraviolet rays, and the paper used for the puffing has the property of reflecting the ultraviolet rays. The blue color sensor 3 receives more ultraviolet rays than the set amount of light set in the pneumoconiosis data through most of the ultraviolet rays, and the counterfeit money reflects most of the ultraviolet rays emitted from the ultraviolet light emitting lamp 3 again and is colored blue. The amount of ultraviolet light received by the sensor 3 becomes smaller than the amount of light set in the occlusion data.

한편, 본 발명에서는 소형의 자외선 발광램프(2)와 저가의 청색컬러센서(3)를 사용하여 위폐를 감별할 수 있도록 함으로서 감별장치를 소형화하고, 제작비를 절감시킬 수 있는 것이다.On the other hand, in the present invention by using a small ultraviolet light emitting lamp (2) and a low-cost blue color sensor (3) to distinguish the forgery, it is possible to miniaturize the discriminating device, and to reduce the manufacturing cost.

상기와 같이 본 발명은 지폐에 자외선을 통과시켜 통과되는 자외선의 광량을 탐지하여 이에 의해 진폐여부를 감별할 수 있도록 함으로서 위조지폐의 감별력을 한 층 더 향상시킬 수 있도록 한 것이다.As described above, the present invention is to detect the amount of ultraviolet light passing through the ultraviolet rays through the bill to thereby discriminate whether or not the pneumococcal, thereby further improving the discriminating power of counterfeit bills.

상기와 같이 본 발명은 소형의 자외선 발광램프와 저가의 청색 컬러센서를 이용하여 지폐감별장치를 구성하고, 지폐용지는 자외선을 통과시키고 위폐에 사용되는 복사용지는 자외선을 반사하는 특성을 이용하여 지폐에 투과되는 광량에 따라 진폐여부를 감별할 수 있도록 함으로서, 위조지폐의 감별률을 극대화함은 물론, 감별장치를 소형화하고, 제작비용을 최소화 할 수 있는 것이다.As described above, the present invention constitutes a bill discrimination apparatus using a small ultraviolet light emitting lamp and a low-cost blue color sensor, and the bill paper passes the UV light and the copy paper used for counterfeiting reflects the UV light. By being able to discriminate whether or not pneumoconiosis according to the amount of light transmitted to it, it is possible to maximize the discrimination rate of counterfeit bills, as well as to miniaturize the discrimination apparatus and minimize the production cost.
