키보드부(1)의 키신호가 빨리감기 또는 되감기 키신호인지를 판별하고, 빨리감기 또는 되감기 키신호일 경우에 캡스턴모터 구동부(4)가 캡스턴모터(M)를 일정속도로 구동시킴과 아울러 공급릴 및 회수릴에 설치한 공급릴 및 회수릴 센서가 각기 검출한 공급릴 및 회수릴펄스신호(TS)(TK)를 입력하고, 빨리감기 또는 되감기 모드인지를 판별하는 키신호 입력루틴과, 상기 키신호 입력루틴에서 빨리감기 모드일 경우에 릴펄스신호(TS) (TK)의 주기(T1)(T2)를 비교하여, T1 N1ㆍT2, T1 N2ㆍT2,…, T1 NNㆍT2가 됨에 따라 출력단자(Q1),(Q2),… ,(QN)로 순차적으로 고전위를 출력하여 구동부(4)가 캡스턴모터(M)의 회전속도를 감속시키게 하는 빨리감기루틴과, 상기 키신호 입력루틴에서 되감기 모드일 경우에 릴펄스신호(TS)(TK)의 주기(T1)(T2)를 비교하여 T2 N1ㆍT1, T2 N2ㆍT1, T1,…, T2 NNㆍT1가 됨에 따라 출력단자(Q1),(Q2),… ,(QN)로 순차적으로 고전위를 출력하여 구동부(4)가 캡스턴모터(M)의 회전속도를 감속시키게 하는 되감기루틴과, 정지신호(ST)가 입력됨에 따라 주브레이크를 구동시켜 캡스턴모터(M)의 회전을 정지시키는 정지루틴으로 제어함을 특징으로 하는 릴펄스신호를 이용한 캡스턴모터의 회전속도 제어방법.It is determined whether the key signal of the keyboard unit 1 is a fast-forward or rewind key signal. When the fast-forward or rewind key signal is used, the capstan motor driving unit 4 drives the capstan motor M at a constant speed and supplies reel. And a key signal input routine for inputting a supply reel and a recovery reel pulse signal TS (TK) respectively detected by the supply reel and the recovery reel sensor installed on the recovery reel, and for determining whether the mode is a fast forward or a rewind mode; In the fast-forward mode in the signal input routine, the period T 1 (T 2 ) of the reel pulse signal TS (TK) is compared and T 1 N 1 ㆍ T 2 , T 1 N 2 ㆍ T 2 ,. , T 1 N N ㆍ T 2 becomes output terminals (Q 1 ), (Q 2 ),. QN is a fast forward routine that outputs a high potential in order to cause the driving unit 4 to slow down the rotational speed of the capstan motor M, and a reel pulse signal in the rewind mode in the key signal input routine. by comparing the period (T 1) (T 2) of the TS) (TK) T 2 N 1 ㆍ T 1 , T 2 N 2 ㆍ T 1 , T 1 ,. , T 2 N N ㆍ T 1 becomes output terminals (Q 1 ), (Q 2 ),. And (Q N ) sequentially outputs a high potential, the rewinding routine for driving the drive unit 4 to decelerate the rotational speed of the capstan motor (M), and driving the main brake as the stop signal (ST) is input to the capstan motor A method of controlling the rotation speed of a capstan motor using a reel pulse signal, characterized in that it is controlled by a stop routine for stopping rotation of (M). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
