Abstract

본 발명은 복사기의 자동노광장치를 개시한다. 개신된 장치는 원고의 농도(흑/백비)를 감지하여 노광램프의 광의 세기를 조절하기 위한 자동노광센서의 전방에 원고의 크기에 따라 자동노광센서의 감지범위를 조절하기 위한 조리개수단이 마련된다. 따라서 원고의 크기에 따라 자동노광센서의 감지범위를 조절할 수 있게 되어 원고의 농도(흑/백비)를 정확하게 감지할 수 있게 된다.The present invention discloses an automatic exposure apparatus of a copying machine. The updated device is provided with an aperture means for adjusting the detection range of the automatic exposure sensor according to the size of the document in front of the automatic exposure sensor for detecting the density of the original (black / white ratio) to adjust the light intensity of the exposure lamp. . Therefore, it is possible to adjust the detection range of the automatic exposure sensor according to the size of the original to accurately detect the density (black / white ratio) of the original.
