Description

원고 농도 검지장치Original Density Detection Device

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

제2도는 본 발명의 원고 농도 검지 장치의 구조도,2 is a structural diagram of a document density detection device of the present invention;

제3도는 빛의 변화량 검출에 따른 램프 전압 처리과정의 블럭도.3 is a block diagram of a lamp voltage process according to the amount of light change detection.

Claims (1)

스캐너에 연동하는 미러(2)와, 원고로 부터 반사되는 빛의 변화량을 검출하는 광센서(8)와, 상기 광센서(8)에서 검출한 빛의 변화량을 소정의 기준값과 비교하여 그 결과로써 램프 전압을 조절하는 마이컴(11)을 구비한 복사기에 있어서, 상기 광센서(8)를 상기 미러(2)에 장착하여 원고 전체의 농도변화를 계속적으로 검출하고, 그 검출 데이타를 상기 마이컴(11)으로 전달하여 원고 전체의 농도 변화를 일정하게 유지할 수 있도륵 구성함을 특징으로 하는 원고 농도 검지장치.The mirror 2 linked to the scanner, the optical sensor 8 for detecting the amount of change in the light reflected from the document, and the amount of change in the light detected by the light sensor 8 are compared with a predetermined reference value as a result. In a copying machine having a microcomputer (11) for adjusting a lamp voltage, the optical sensor (8) is mounted on the mirror (2) to continuously detect the density change of the entire document, and the detected data is stored in the microcomputer (11). Original density detection device characterized in that it is configured to maintain a constant change in density of the entire document by passing through. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
