Abstract
Description
Claims (1)
- 키보드부(1)에서 마이크로처리장치(2)에 키신호가 입력될때 그 키신호가 슬로우키신호인 경우에는 슬로우플래그를 세트시키고, 그 슬로우플래그가 세트되어 있는 상태에서 상기 키신호가 슬로우업 또는 슬로우다운 키신호인 경우에는 슬로우업 또는 슬로우다운 플래그를 세트시키는 키신호처리루틴과, 슬로우플래그가 세트되어 있는 상태에서 슬로우업플래그 또는 슬로우다운 플래그가 세트될때 그 슬로우업 플래그 또는 슬로우다운 플래그를 리세트시킨 후 슬로우카운터를 설정하는 저속모드 제어푸틴과, 지연플래그가 세트되지 않는 경우에는 l시간만큼 캡스턴모터를 구동시키기 위한 신호를 출력시킨 후, 지연플래그가 세트된 경우에는 곧바로 캡스턴모터의 구동을 중지시키고, 이후 지연플래그를 세트시킨후 상기 슬로우 카운터값을 슬로우타임 카운터값으로 하고, 그 슬로우타임 카운터값에 따라 그 슬로우타임 카운터값에 소정시간(n)을 곱한 후 상기 캡스턴모터의 구동을 중지시키는 시간(m)에 가감시키는 슬로우타임 제어루틴으로 제어함을 특징으로 하는 브이 알의 저속모드시 속도제어방법.
