Abstract
Description
Claims (1)
- 모터에 의해 복사기의 광학계의 드럼을 구동시키게 된 것에 있어서 광학계(가)를 구동하는 광학계 구동모터(13)의 회전속도를 검출하는 인코더(19)와 드럼(10)을 구동하는 드럼구동모터(21)의 회전속도를 검출하는 검출기(22)의 출력을 제어장치(20)에 연결하되, 검출기(22)의 출력은 파형정형 회로(23)를 통해 마이크로 프로세서(27)와 배율선정회로(45)가 연결된 프로그램 가능한 분주기(25) 입력에 연결하고, 분주기(25)출력은 위상 비교기(33)와 속도비교기(34)의 일측입력에 연결하되, 위상비교기(33)와 속도 비교기(34)의 타측입력에는 파형 정형 회로(30)를 통한 인코더(19)의 출력신호가 입력되도록 하며, 그 출력은 각각 저항(37, 38)을 통해 일측입력(+)이 톱니파 발생기(41)에 연결된 비교기(39)의 타측입력(-)이 공통접속하고 비교기(39)의 출력은 저항(49)을 통해 에미터가 접지되고 콜렉터에는 광학계 구동모터(13)에 연결된 트랜지스터(44)의 베이스에 연결하여서된 복사기의 광학계 구동제어장치.
