Abstract

본 발명은 레이저 프린터에서 내부로 이송 공급되는 페이퍼에 묻은 토너를 열융착하여 굳혀주는 장착기롤러의 가열롤러와 가압롤러자동 분지장치에 관한 것으로서, 특히 레이저 프린터의 내부 일측에 설치되며, 가열롤러와 가압롤러로 구성되는 정착기롤러의 일측으로 3개의 이격홈으로 구성되는 회전캠을 기어와 함께 설치하고, 이 기어와 맞들려지게 일측에는 클러치기어를 설치하여 구동도터와 연결되는 연동기어와 맞물려지게 구성하고 상기 정착기 롤러의 양측에는 스위치를 설치하여 페이퍼가 공급될때에만 가열롤러와 가압롤러가 밀착되게 하고, 페이퍼가 공급되지 않을 때에는 상기 두개의 롤러를 분리시켜 가압롤러를 보호하여줄 수 있게한 레이저 프린터의 장착기롤러 자동 분지장치에 관한 것이다.The present invention relates to a heating roller and a pressure roller automatic branching device of a mounting roller that thermally fuses and toners adhered to paper fed from a laser printer, and is installed on one side of the laser printer. One side of the fixing roller, which consists of rollers, is provided with a rotating cam composed of three spaced grooves together with gears, and a clutch gear is installed on one side to mesh with the interlocking gear connected to the drive daughter. And a switch installed at both sides of the fuser roller so that the heating roller and the pressure roller are in close contact only when the paper is supplied, and the two rollers are separated to protect the pressure roller when the paper is not supplied. The automatic roller branching apparatus of the mounter of the present invention.
