Abstract

건식 전자사진 프로세서의 복사장치에 관한 것으로서, 특히 다른 기종인 레이저 빔 프린터등을 차후에 사용할 수 있도록 설계된 프로세스 기술도로써 작은공간을 차지하고 가격이 저렴하면서 확대기능을 갖는 복사기의 프로세스에 관한 기술이다.The present invention relates to a copying apparatus for a dry electrophotographic processor, and more particularly, a process technology designed to use a laser beam printer, which is another model, in the future.

기존에는 일반적인 복사기가 차지하는 공간이 크고 다른 기종으로 사용할 수 없게 복사장치의 프로세스가 구성되어 있으며 대전기와 전사기 및 분리기에서의 코로나 방전을 일으키므로 방전시 발생하는 오존 및 질소 산화물에 의하여 유기질로된 감광드럼이 손상을 입게 되며 대전기 및 전사기의 블로킹 층이 파괴되어 대전되는 전압이 빠져나가게 되어 화상에 영향을 주어 화질의 저하를 초래하는 문제점이 있어 이를 해결하기 위하여 복사장치의 프로세스에 다른 기종의 레이져 빔 프린터와 디지탈 복사기 및 이미지 센서등의 기기를 겸해서 사용할 수 있도록 하부본체 일측에 복사 프로세스를 설치하여 하측에서 용지가 급지되어 상측으로 배지되게 하여 복사기가 차지하는 공간을 작게하며 대전기 및 전사기를 고도전성률을 사용하여 감광드럼을 손상시키지 않고 화상에 영향을 주지 않도록 하여 화질을 향상 시킬 수 있는 것이다.In the past, the process of the copying device is composed of a large space occupied by a general copier and cannot be used with other models. Since it causes corona discharge in a charger, a transfer machine, and a separator, it is organically exposed by ozone and nitrogen oxide generated during discharge. The drum is damaged and the blocking layers of the charger and the imprinter are destroyed, and the charged voltage is discharged, which affects the image and causes a deterioration in image quality. A copy process is installed on one side of the lower body so that it can be used as a laser beam printer, digital copier, and image sensor, and paper is fed from the lower side to discharge to the upper side. Use the malleability to Without phase and so as not to affect the image is capable of improving the image quality.
