Abstract

이 발명의 테이프 주행장치의 주행속도 제어방법은 테이프 이송시 테이프 전투영 면적을 산출하는 단계와, 그 산출된 테이프 전투영 면적으로부터 테이프 속도정보가 산출되고 그 값을 저장하는 단계와, 현재의 속도정보와 저장된 속도정보를 비교하여 캡스턴모터의 회전주기를 가변시켜 테이프 속도를 제어하는 단계로 이루어져서, 테이프 주행속도를 가변시킬 경우 별도의 서보장치가 필요없이도 가능하므로 생산비 절감등의 효과가 있는 매우 유용한 발명이다.The traveling speed control method of the tape traveling apparatus of the present invention comprises the steps of: calculating a tape battle field area during tape transfer; calculating tape speed information from the calculated tape battle field area and storing the value; and present speed The tape speed is controlled by varying the rotation period of the capstan motor by comparing the information with the stored speed information. When changing the tape running speed, it is possible to save the cost of production because there is no need for a separate servo device. Invention.
