광센서를 이용한 투명테이프가 부착된 지폐의 감별장치{omitted}Apparatus for discriminating banknotes with transparent tape using optical sensor {omitted}

본 발명은 광센서를 이용하여 투명테이프가 부착된 지폐를 감별할 수 있는 감별장치에 관한 것으로, 특히 동전교환기, 자동판매기 등에 사용되는 지폐인식기에 지폐가 투입시 적색 LED와 적외선 센서를 이용하여 투명테이프가 부착된 지폐를 감별해 낼 수 있도록 함으로서, 보다 정확히 지폐에 투명테이프의 부착여부를 판단할 수 있도록 함은 물론, 제작비를 절감할 수 있는 광센서를 이용한 투명테이프가 부착된 지폐의 감별장치에 관한 것이다.The present invention relates to a discriminating device that can discriminate banknotes with a transparent tape using an optical sensor, and in particular, when a banknote is inserted into a banknote recognizer used in a coin exchanger or a vending machine, it is transparent using a red LED and an infrared sensor. By making it possible to discriminate banknotes with tape, it is possible to judge whether the transparent tape is attached to the banknotes more accurately, as well as to identify banknotes with transparent tape using an optical sensor that can reduce manufacturing costs. It is about.

투명 또는 불투명 테이프가 부착된 지폐는 지폐인식기 등 지폐를 처리하는 기계에서 지폐걸림현상 등을 초래하기 때문에 테이프가 부착된 지폐를 가려내는 장치가 반드시 필요하다.Since a banknote with a transparent or opaque tape is attached to a banknote processing machine such as a banknote recognizer, a paper jam may occur.

따라서 종래에는 지폐의 두께를 감지하거나 광센서를 이용한 패턴의 인식방법으로 테이프가 부착된 지폐를 감별하는 장치가 개발되어 사용되어지고 있다.Therefore, in the related art, a device for discriminating banknotes with a tape has been developed and used as a method of detecting a thickness of a banknote or recognizing a pattern using an optical sensor.

그러나 상기와 같은 종래의 감별장치 중 광센서를 이용하여 패턴을 인식하도록 구성된 경우 불투명한 테이프가 부착된 지폐를 감지하는 데는 어느 정도 효과가 있으나 투명한 테이프가 부착된 지폐는 빛의 반사량이 미미하여 감별이 곤란한 문제점이 있으며,However, if the conventional discriminating device is configured to recognize a pattern using an optical sensor, it is effective to detect a bill with an opaque tape, but the banknote with a transparent tape has a small amount of light reflection to discriminate. There is a difficult problem,

두께측정센서를 이용한 감별장치는 제작시 기술적 난이도가 높고, 고가인 두께측정센서를 사용해야 하므로 제작비가 상승하게 되는 문제점이 있었다.The discrimination apparatus using the thickness measuring sensor has a problem in that the manufacturing cost increases because the technical difficulty of manufacturing and the expensive thickness measuring sensor must be used.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 저가의 적색 LED와 적외선 센서를 경사상으로 설치하여 지폐에 부착된 테이프에 의해 반사되는 반사광의 량을 측정하여 그 결과에 따라 투명테이프의 부착여부를 판단할 수 있도록 함으로서, 테이프가 부착된 지폐의 감별률을 극대화함은 물론 , 제작비용을 최소화 할 수 있는 광센서를 이용한 투명테이프가 부착된 지폐의 감별장치를 제공함에 본 발명의 목적이 있다.The present invention has been made in order to solve the above problems, by installing a low-cost red LED and an infrared sensor in an inclined shape to measure the amount of reflected light reflected by the tape attached to the banknote and according to the result of the transparent tape The object of the present invention is to provide a device for discriminating bills with a transparent tape using an optical sensor that can maximize the discrimination rate of bills with tapes as well as minimize manufacturing costs by allowing them to determine whether they are attached. There is this.

기판(1)(1')의 상하부에 적색 LED(2)와 적외선 센서(3)가 경사상으로 결합되어 구성된 테이프 감지장치를 다수 설치하고, 상하쪽 테이프 감지장치 사이의 기판(1)(1')상에 투과공(4)을 형성하되,In the upper and lower portions of the substrate (1) (1 '), a plurality of tape sensing devices constituted by the red LED (2) and the infrared sensor (3) are inclinedly coupled, and the substrate (1) (1) between the upper and lower tape sensing devices is installed. Form a through hole (4) on

적색 LED(2)로부터 방사되어 지폐에 의해 반사되는 적외선을 수광한 적외선센서(3)로부터 출력된 광량을 기저장된 설정 데이터와 비교하여 테이프의 부착여부를 판정하고, 그 결과를 표시부와 통신부에 전송하여 결과를 디스플레이하고 지폐를 통과 또는 반환시키는 제어부로 구성한 것이다.The amount of light output from the infrared sensor 3, which received the infrared rays emitted from the red LED 2 and received by the banknote, is compared with the previously stored setting data to determine whether the tape is attached, 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 테이프가 부착된 지폐의 감별장치를 사용하여 지폐를 감별시에는 감별장치에 전원을 인가하여 다수의 적색 LED(2)와 적외선 센서(3)를 작동시킨다 (S10).When discriminating banknotes using the tape discrimination apparatus with the tape of the present invention, power is applied to the discriminator to operate the plurality of red LEDs 2 and the infrared 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 적색 LED(2)로부터 방사되는 적외선이 기판(1)(1')상의 투과공(4)을 통해 지폐(7)에 반사되고, 지폐(7)에 의해 반사된 적외선을 적외선 센서(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). The infrared rays emitted from the red LED 2 at the same time as passing through the 5 and the banknote withdrawal unit 6 are reflected on the banknote 7 through the transmission hole 4 on the substrate 1, 1 ', and the banknote ( Infrared sensor 3 detects the infrared rays reflected by 7) and transmits a signal to the controller (S20).

적외선 센서(3)로부터 적외선의 광량을 인지한 제어부는 이를 기 설정된 설정 데이터의 설정값과 비교한다(S30).The controller, which recognizes the amount of infrared light from the infrared sensor 3, compares the amount of infrared light with a preset value of preset data (S30).

적외선 센서(3)에 수광된 적외선의 광량과 설정 데이터의 설정광량을 비교하여(S40) 수광된 적외선의 광량이 설정광량보다 작을 경우에는 기타 다른 항목을 검출하여(S50) 지폐 인출부(6)를 통해 배출한 후 또 다른 지폐의 투입을 요구하는 신호를 출력시키고,The amount of infrared light received by the infrared sensor 3 is compared with the set light amount of the setting data (S40), when the amount of received infrared light is smaller than the set light amount, other items are detected (S50), and the bill extractor 6 After discharging through and outputting a signal requiring the input of another bill,

수광된 광량이 설정광량보다 클 때에는 지폐(7)를 지폐 투입부(5)를 통해 다시 반출시키는 신호를 출력시켜(S70) 지폐에 테이프(8)의 부착여부를 가려내는 것이다.When the amount of received light is greater than the set amount of light, a signal for carrying out the bill 7 again through the bill input unit 5 is output (S70) to determine whether the tape 8 is attached to the bill.

상기와 같은 작용에 의해 지폐의 테이프(8) 부착여부 감별이 가능한 것은 불투명 또는 투명테이프가 지폐에 부착되어 있는 경우 적색 LED(2)로부터 방사되는적외선이 테이프(8)에 의해 대부분 다시 반사되므로 적외선 센서(3)에서 수광하게되는 적외선의 광량이 테이프(8)가 부착되어 있지 않을 때의 광량보다 많아지기 때문이다.It is possible to discriminate whether the tape 8 is attached to the banknote by the above-mentioned action. In the case where the opaque or transparent tape is attached to the banknote, the infrared rays emitted from the red LED 2 are mostly reflected back by the tape 8, and thus the infrared rays This is because the amount of infrared light received by the sensor 3 is larger than the amount of light when the tape 8 is not attached.

한편, 본 발명에서 적색 LED(2)와 적외선 센서(3)의 경사 각도(a)는 약 30° 이내로 하는 것이 바람직하다.On the other hand, in the present invention, the inclination angle a of the red LED 2 and the infrared sensor 3 is preferably within about 30 °.

상기와 같이 본 발명은 지폐(7)에 부착된 투명 또는 불투명 테이프(8)를 비교적 저가의 적색 LED(2)와 적외선 센서(3)를 설치하여 감별해 낼 수 있도록 함으로서, 정확도를 향상시키고, 제작비를 절감할 수 있도록 한 것이다.As described above, the present invention allows the transparent or opaque tape 8 attached to the banknote 7 to be discriminated by installing a relatively low-cost red LED 2 and an infrared sensor 3, thereby improving accuracy, It is to reduce the production cost.

상기와 같이 본 발명은 비교적 저가의 적색 LED와 적외선 센서를 경사상으로 설치하여 지폐에 부착된 테이프에 의해 반사되는 반사광의 량을 측정하여 그 결과에 따라 투명테이프의 부착여부를 판단할 수 있도록 함으로서, 테이프가 부착된 지폐의 감별률을 극대화함은 물론, 제작비용을 최소화 할 수 있는 것이다.As described above, the present invention is to install a relatively low-cost red LED and an infrared sensor to measure the amount of reflected light reflected by the tape attached to the bill to determine whether the transparent tape is attached according to the result In addition to maximizing the discrimination rate of bills with tapes, the manufacturing cost can be minimized.
