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

제 3 도는 본 발명에 따른 센서위치 및 복사기구도. 제 4 도는 본 발명에 따른 복사용지의 크기표시 및 제 2 센서 위치도. 제 6 도는 본 발명에 따른 시스템 블럭도.3 is a sensor position and radiation mechanism according to the invention. 4 is a view showing the size of the copy paper and the second sensor position according to the present invention. 6 is a system block diagram according to the present invention.

Claims (1)

복사기의 원고크기 및 농도검지 방법에 있어서, 노광램프점등 후 원고크기 센서의 출력을 검지하여 원고의 크기를 인식한후 그에 대응된 해당 플레그를 세트하는 제 1 과정과, 상기 제 1 과정 수행후 캐리지를 포워드 스캔하여 원고농도 센서출력을 검지 원고의 농도가 적당한가 점검후 적당하지 않으면 밝기제어 신호를 변화시켜 노광램프의 발광상태를 적당한선으로 세팅하는 제 2 과정과, 상기 제 2 과정 수행후 상기 제 1 과정에서 인식한 크기로 스캐닝을 완료했는가 점검하여 완료했으면 상기 노광램프를 소등한 뒤 홈위치까지 리턴하는 제 3 과정과, 상기 제 3 과정 수행후 원고크기를 표시하고 원고의 크기에 적당한 카세트를 선택한후 노광램프를 점등하여 상기 원고끝 위치까지 스캔하고 다시 홈 위치까지 캐리지 리턴하는 제 3 과정으로 구성됨을 특징으로 하는 복사기의 원고크기 및 농도검지방법.In the document size and density detection method of the copier, a first process of detecting the size of the document after detecting the output of the document size sensor after the exposure lamp is turned on, and setting a corresponding flag corresponding to the original, and the carriage after performing the first process Detect the document density sensor output by forward scanning, and if it is not appropriate after checking the document density, change the brightness control signal to set the light emission state of the exposure lamp to the appropriate line, and after performing the second process, In step 1, if the scanning is completed in the size recognized in step 1, and the inspection is completed, the third step of turning off the exposure lamp and returning to the home position, and displaying the original size after performing the third step, and inserting a cassette suitable for the original size After the selection, the exposure lamp is turned on to scan to the document end position and the carriage returns to the home position. Characteristic size and density detection method of the copier. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
