Abstract

LSU프린팅방식과 LED프린팅 방식을 겸용할 수 있는 광프린터에 있어서, LSU/LED프린팅 제어를 위한 제어신호를 발생하고, 상기 LED제어용 수평동기 신호의 주기와 일정 주기의 카운팅 신호를 발생하여 상기 양 출력을 비교하여 같을때 LED제어방식의 수평동기 신호에 대응하는 신호를 발생한다.
각부 제어용 기준 클럭신호를 발생하고, 상기 클럭발생을 기준 클럭발생 신호로 하여 수평동기 신호에 의해 비디오 클럭신호를 발생하고 상기 클럭발생을 기준 클럭발생 신호로 하여 데이타 래치 신호를 발생하며, 상기 래치신호 데이타 래치 결과에 따라 기준 클럭에 의해 LED제어방식의 LED발광을 위한 스토로브 신로를 발생하여 상기 LED/LSU제어신호 출력에 의해 레이저 빔 디텍터 신호와 상기 비교된 출력을 선택하여 수평동기 신호 LSU/LED방식을 선택제어 겸용토록 되어 있다.
