Abstract
본 발명은 레이저 빔 프린터의 다기능 카세트 용지 검지장치에 관한 것으로서, 다양한 레이저 빔 프린터의 용지를 하나의 카세트로 처리할 경우에 현재 사용중인 용지가 어떤 크기의 용지인가를 별개의 센서 및 구동회로에 의해 확인 하도록 한것이다.The present invention relates to a multi-function cassette paper detection device of a laser beam printer, wherein when the papers of various laser beam printers are processed into one cassette, the size of the paper being used is determined by a separate sensor and a driving circuit. I checked it.
이와 같은 본 발명의 목적은 레이저 빔 프린터 카세트 내 용지의 크기를 감지하는 스위칭부와, 상기 스위칭부의 각 스위치에 따른 구동 전압과 기준 전압을 비교하는 비교부와, 상기 비교부에 따른 각 비교기의 출력 전압을 엔코딩 하는 엔코더와, 상기 엔코더의 출력값에 따라 용지의 크기를 판단 및 처리하는 중앙 처리장치와, 상기 중앙 처리장치의 판단에 의해 용지의 크기를 표시하는 디스플레이 모듈을 이루어짐으로써 달성되는 것이다.The object of the present invention is a switching unit for sensing the size of the paper in the laser beam printer cassette, a comparison unit for comparing the drive voltage and the reference voltage according to each switch of the switching unit, and the output of each comparator according to the comparison unit It is achieved by forming an encoder for encoding a voltage, a central processing unit for determining and processing the paper size according to the output value of the encoder, and a display module for displaying the paper size by the determination of the central processing unit.
