키매트릭스부(1)의 키를 눌러 그 키신호가 마이콤(2)에 입력됨에 따라 그 키신호 데이타를 어큐뮬레이터(A)에 저장하고, T 및 SPY 레지스터(Y),(SPY)에 저장된 신호를 상호 교환한후 어큐뮬레이터(A)에 저장된 신호를 Y 레지스터(Y)에 저장하고, 다시 키신호 데이타를 어큐뮬레이터(A)에 저장하고 Y레지스터(Y)에 저장된 신호에서 감산한 후 Y레지스터(Y)에 저장된 신호가 제로인지를 판별하고, 제로일 경우에 어큐뮬레이터(A)에 저장된 신호가 제로인지를 판별하여 제로가 아닐 경우에는 정상적인 키신호 입력을 감지하고 제로일 경우 및 상기 Y레지스터(Y)에 저장된 신호가 제로가 아닐 경우와 동일하게 상기 Y 및 SPY레지스터(Y),(SPY)에 저장된 신호를 상호 교환한 후 각각 차기루틴 수행 및 원상복귀하는 키신호 에러 검출루틴과, 상기 키신호 에러검출 루틴에서 정상적인 키신호일 경우에 그 키신호가 이젝트 키신호 인지를 판별하여 각각 이젝트 키신호 및 정지키신호일 경우에는 이젝트 및 정지동작을 각각 수행하고, 이젝트 키 및 정지 키신호가 아닐 경우에 빨리감기 키신호인 경우나 되감기 키신호일 경우에는 재생모드 여부에 따라 빨리감기 및 되감기, 전진 및 후진 고속재생을 각각 수행하고, 상기에서 빨리감기 및 되감기 키신호 아닐 경우에 고속서치 키신호인지를 판별하여 고속서치 키신호일 경우에는 전진 및 후진 고속재생인지를 각각 판별하고, 전진 및 후진 고속재생일 경우에는 동일하게 마이콤(2)의 서치 제어 출력포트(SO4)로 고전위신호를 출력하고, 상기에서 고속서치키신호가 아닐 경우에는 다른 키신호 판별에 따른 키신호에 따른 동작을 수행하게 제어한 후 상기에서 모든 동작 수행후와 동일하게 초기상태로 원상복귀하는 키신호 판별 루틴으로 제어함을 특징으로 하는 캡스턴 모터의 회전속도 제어방법.As the key signal is input to the microcomputer 2 by pressing the key of the key matrix unit 1, the key signal data is stored in the accumulator A, and the signals stored in the T and SPY registers Y and SPY are stored. After mutual exchange, the signals stored in the accumulator (A) are stored in the Y register (Y), the key signal data is again stored in the accumulator (A) and subtracted from the signals stored in the Y register (Y), and then the Y register (Y). If the signal stored in the accumulator (A) is zero, and if the signal stored in the accumulator (A) is zero, if it is not zero, it detects the normal key signal input, and if it is zero and the Y register (Y) And a key signal error detection routine for performing the next routine and returning to each other after exchanging signals stored in the Y and SPY registers (Y) and (SPY) as in the case where the stored signal is not zero, and the key signal error detection. Still life in the routine If the key signal is an eject key signal, the controller determines whether the key signal is an eject key signal, and if it is an eject key signal or a stop key signal, respectively, it performs eject and stop operations, respectively. In the case of a rewind key signal or a rewind key signal, fast forward and rewind, fast forward and reverse fast playback are performed respectively, and if it is not a fast forward or rewind key signal, the fast search key signal is determined. In the case of fast forward and reverse fast regeneration, respectively, in the case of forward and reverse fast regeneration, the high potential signal is output to the search control output port SO 4 of the microcomputer 2 in the same way. If not, control to perform the operation according to the key signal according to the determination of the other key signal and the same as after performing all the above operations. To the rotational speed control of the capstan motor characterized in that the control of key signal discrimination routine to return to original state to the initial state. 키매트릭스부(1)의 키신호에 따라 시스템 전체의 동작을 제어하는 마이콤(2)과 상기 마이콤(2)의 출력신호에 따라 일정전압을 조절 출력하는 전압조절부(3) 및, 서치제어전압을 출력하는 서치 제어부(4)와, 상기 전압조절부(3) 및 서치 제어부(4)의 출력신호에 따라 캡스턴 모터의 구동제어 전압을 출력하는 캡스턴 모터구동제어부(5)로 구성함을 특징으로 하는 캡스턴 모터의 회전속도 제어회로.The microcomputer 2 for controlling the operation of the entire system according to the key signal of the key matrix unit 1, the voltage adjusting unit 3 for regulating and outputting a constant voltage according to the output signal of the microcomputer 2, and the search control voltage. And a capstan motor drive control unit 5 for outputting a driving control voltage of the capstan motor according to the output signal of the voltage adjusting unit 3 and the search control unit 4. Rotational speed control circuit of the capstan motor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
