Claims (1)

해드부(1)의 제어펄스(CTL) 출력단자와 캡스턴 모터(CM)의 주파수 발생 펄스(CFG) 출력단자에 각각 증폭부(AMP1, AMP2)를 연결하고, 이 증폭부(AMP1, AMP2)의 출력 단자에 마이콤(Micom)을 연결하는데 이 마이콤(Micom)에는 입력된 제어 펄스(CTL)와 주파수 발생 펄스(CFG)를 마이콤(Micom)이 제어할 수 있는 신호로 변환되며, 이 변환된 신호를 제어펄스(CTL) 주파수 발생펄스(CFG)의 수를 카운팅하여 저장하고, 이 카운팅을 N의 실시하여 표본화를 하며, 이 표본화된 데이터와 기준이 되는 방송 방식의 데이터를 비교하여 테이프 수록된 방송방식을 판별하고 이 판별된 방송 방식에 따라 캡스턴 모터(CM)을 제어할 수 있는 신호를 변환하여 출력되도록 제어하는 프로그램이 내장되어 있고, 이 마이콤(Micom)의 출력 단자에 제어펄스(CTL)와 주파수 발생 펄스(CFG)를 입력으로 하는 서보 집적회로(SIC)를 연결하며, 이 서보 집적회로(SIC)의 출력단자는 캡스턴 모터(CM)의 제어부에 연결 구성함을 특징으로 하는 재생시 테이프의 방송 방식 검출회로.The amplifiers AMP1 and AMP2 are connected to the control pulse CTL output terminal of the head unit 1 and the frequency generating pulse CFG output terminal of the capstan motor CM, respectively. Micom is connected to the output terminal, and Micom converts the input control pulse (CTL) and frequency generating pulse (CFG) into a signal that can be controlled by Micom, and converts the converted signal. Count and store the number of control pulse (CTL) frequency generation pulses (CFG), perform this counting for sampling, compare the sampled data with the reference broadcasting data, There is a program to control and convert a signal capable of controlling the capstan motor (CM) according to the determined broadcasting method, and to output the control pulse. The control terminal (CTL) and the frequency are generated at the output terminal of the micom. Servo with pulse (CFG) as input And an integrated circuit (SIC), wherein an output terminal of the servo integrated circuit (SIC) is connected to a control unit of a capstan motor (CM). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
