Abstract

발명은 레이저 프린터의 레이저 주사장치에 관한 것으로, 종래에는 주사시작신호는 주사속도를 예상하여 다음면의 예측시간보다 조금 앞에서 시켜주어야 하므로 레이저다이오드를 제어하기 위한 복잡한 회로를 필요로 하고, 이 회로를 통과하면서 노이즈등에 의해 화상흔들림이 발생되는 문제점이 있었다.
따라서 종래의 문제점을 해결하기 위하여 본 발명은 폴리곤미러의 상측에 광학패턴 및 위치감지용 패턴을 설치하고, 그 패턴상측에 발광소자 및 수광소자를 설치하여 폴리곤미러의 회전속도에 관계없이 광학패턴의 회전속도도 같은 속도로 변화되어 항상 주사시작영역통과시 레이저를 켤 수 있도록 하였다.
