Claims (2)

  1. 장착된 회전체를 그 축심을 중심으로 회전구동하는 회전구동수단과, 회전구동수단의 회전위치를 검출하는 부호기와 부호기로부터의 신호가 입력되어서 회전구동수단을 등속으로 회전구동하도록 제어하는 회전제어수단과, 등속으로 회전하고 있는 회전체의 임의위치에 대한 처리를 행하는 처리수단을 구비한 회전체에 대한 처리장치에 있어서, 상기 부호기로부터의 신호에 의거해서 회전체의 회전위치를 분해능을 높여서 검출하는 위치검출수단을 배설하는 동시에, 그 검출위치에 의거해서 상기처리수단 또는 처리수단으로부터의 출력신호를 제어하는 처리제어수단을 설치한 것을 특징으로하는 회전체에 대한 처리장치.
  2. 제1항에 있어서, 상기 위치검출수단이 부호기로부터 출력되는 펄스신호를 카운트하는 카운터 및 펄스신호 사이에 있어서 경과시관과 펄스신호의 주기로부터 보간연산을 행하는 수단과, 상기 카운터 및 보간연산수단의 신호에 의거해서 위치를 연산하는 수단을 구비하고 있는 것을 특징으로 하는 회전체에 대한 처리장치.
