Abstract

본 발명은 자동판매기의 솔레노이드배선회로에 관한 것으로, 특히 배선회로의 단선을 검출하기 위하여 커런트트랜스(CT), 저항(R1), 다이오드(D1), 콘덴서(C1) 등으로 이루어진 감지부(21)를 서어지흡수용릴레이(RY0)의 스위치부의 일단과 판매용릴레이(RY1)의 스위치부의 일단에 개재접속하여 전류흐름의 유무를 판단함으로써, 전류가 흐르지 않을시 단선 상태임을 판단하여 단선상태 표시부(13)에 단선을 나타내는 해당 칼럼 매진 램프를 이용하여 외부로 알려줄 뿐만 아니라 투입된 동전을 반환해 주는 이점이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solenoid wiring circuit of a vending machine. In particular, the sensing unit includes a current transformer (CT), a resistor (R 1 ), a diode (D 1 ), a capacitor (C 1 ), and the like to detect disconnection of the wiring circuit. 21 is connected to one end of the switch portion of the surge absorption relay RY 0 and one end of the switch portion of the sales relay RY 1 to determine whether there is a current flow, thereby determining that there is a disconnection state when no current flows. The disconnection state display unit 13 has an advantage of notifying the outside as well as returning the input coins by using the corresponding column sold out lamp indicating the disconnection.
