복사기의 원고 유, 무 검지방법How to detect whether a copier has a document

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명 복사기의 구성도, 제3도는 본 발명 원고 유, 무 검지회로도.2 is a schematic diagram of the copier of the present invention, and FIG.

Claims (1)

복사기 본체(1), 원고대 유리(11), 복사버튼(4), 원고대 커버(10)로 구성한 복사기에 있어서, 상기 복사버튼(4)의 온-오프시 원고대 유리(11)에 놓여진 원고(13)의 유, 무를 검지하는 원고검지부(2)와, 상기 원고검지부(2)의 출력신호와 기준전위를 비교하는 비교부(3)와, 상기 비교부(3)의 출력신호에 따라 복사기의 전체동작을 제어하는 마이컴(1)과, 상기 마이컴(1)의 출력신호에 따라 원고(13)의 유, 무를 확인하여 주는 발광다이오드(LED2)를 구비한 후 복사버튼(4)을 턴-온시켜 원고검지부(2)로 원고대 유리(11)에 올려진 원고(13)의 유, 무 검지하고, 원고(13)가 없으면 마이컴(1)이 노광램프 및 구동모터를 오프시킴과 아울러 원고 유, 무 확인용 발광다이오드(LED2)를 턴-온시켜 시스템을 초기상태로 유지시키고, 원고(13)가 있을시에는 노광램프와 구동모터를 턴-온시켜 복사매수에 따라 반복수행함을 특징으로 한 복사기의 원고 유, 무 검지방법.In the copier comprising the copier body 1, the platen glass 11, the copy button 4, and the document cover 10, the copy button 4 is placed on the platen glass 11 when the copy button 4 is turned on and off. According to the original detection unit 2 for detecting the presence or absence of the original 13, the comparison unit 3 for comparing the output signal of the original detection unit 2 with the reference potential, and the output signal of the comparison unit 3 A microcomputer 1 for controlling the overall operation of the copier and a light emitting diode LED2 for checking the presence or absence of the original 13 according to the output signal of the microcomputer 1 are turned on, and then the copy button 4 is turned on. When the document 13 is turned on, the document detection unit 2 detects whether or not the document 13 is placed on the platen glass 11, and if there is no document 13, the microcomputer 1 turns off the exposure lamp and the driving motor. Turn on the original or unchecked light emitting diode (LED2) to keep the system in the initial state.If there is a document (13), turn on the exposure lamp and drive motor. Original oil, how non-detection of a copier characterized by carrying out repeated according to the number of sheets used. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
