Abstract

본 발명은 전자사진 기록장치의 현상기 구동장치에 관한 것으로서, 특히 현상기내에 설치된 현상롤러인 슬리브와 마그네트롤러를 각각 구동시키고 에지데이터를 구동시키는 구동장치에 관한 기술이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a developing apparatus driving apparatus for an electrophotographic recording apparatus, and more particularly, to a driving apparatus for driving a sleeve and a magnet controller, which is a developing roller installed in a developing apparatus, and driving edge data.

종래의 현상기 구동장치는 고속회전을 하는 마그네트롤러와 상대적으로 저속회전을 하는 슬리브와 에지테이터를 회전시키기 위하여 현상모타를 현상기하우징에 직접 부착시키므로 모타의 진동과 소음 및 열이 슬리브와 감광드럼에 영향을 미쳐 인자의 품질을 저하시키며, 열에 의해 토너가 고착되는 경우가 발생된다. 또한 현상기가 소모품으로서 모타가 취부되어 있어 가격이 비싸고 부피가 커지는 문제점이 있었다. 본 발명은 현상기하우징에는 마그네트롤러 외부에 슬리브가 회전되게 설치된 현상롤러와 토너를 교반하는 에지테이터를 설치하여 상기 현상롤러와 에지테이터를 회전시키는 동력전달기어를 각각 설치하고, 본체 프레임에는 현상모타와 풀리기어와 아이들기어를 설치하여 현상모타의 동력이 현상롤러와 에지테이터를 동시에 회전시킬 수 있도록 설치된 것으로서, 현상기하우징에서 현상모타를 분리하여 본체프레임에 설치하므로서, 현상모타의 소음과 진동 및 열에 의해 슬리브와 감광드럼에 미치는 영향을 방지하여 인자 품질을 향상시킬 수 있으며, 소모품인 현상기의 원가를 절감시키고, 부피를 줄일 수 있는 잇점이 있다.Conventional developer drive device directly attaches developing motor to developer housing to rotate high speed rotating magnet controller and relatively low speed rotating sleeve and edge data. Therefore, vibration, noise and heat of motor affect sleeve and photosensitive drum. This results in deterioration of the quality of the printing, and occurs when the toner is fixed by heat. In addition, since the motor is installed as a consumable as a consumable, there is a problem that the price is high and bulky. According to the present invention, a developing roller and an edge taper for agitating toner are installed on a magnet housing, and a power transmission gear for rotating the developing roller and the edge data is installed in the developing housing, and a developing motor and It is installed so that power of developing motor can rotate the developing roller and edge data at the same time by installing pulley gear and idle gear.The developing motor is separated from developing housing and installed in main frame. It is possible to improve the printing quality by preventing the influence on the sleeve and the photosensitive drum, and to reduce the cost and the volume of the developing device as a consumable.
