Claims (2)

입력펄스(P)가 증폭기(1) 및 모노멀티(2)를 통하여 시정수에 의한 지연신호를 발생시키고 주파수발생기(3)를 통하여 스위칭신호용주파수(SW30Hz)가 스위칭되는 헤드 스위칭 제어장치에 있어서, 키보드(7)의 키입력(K)을 마이컴(6)에 인가함과 아울러 수직동기신호(V.S) 및 스위칭 신호용주파수(SW30Hz)를 상기 마이컴(6)에 인터럽트(I1),(I2)시키고, 그에 따른 디지탈 신호를 아날로그신호로 변화시켜 상기 모노멀티(2)에 인가하는 디지탈/아날로그 변환기(4)와, 상기 디지탈/아날로그 변환기(4)의 출력데이타를 저장하여 다른 세트와의 호환성을 유지하는 이이피롬(5)으로 구성된 것을 특징으로 하는 자동 헤드 스위칭 제어장치.In the head switching control device in which the input pulse P generates a delay signal by a time constant through the amplifier 1 and the mono multi 2, and the switching signal frequency SW30 Hz is switched through the frequency generator 3. The key input K of the keyboard 7 is applied to the microcomputer 6, and the vertical synchronization signal VS and the switching signal frequency SW30 Hz are interrupted by the microcomputer 6 (I 1 ) and (I 2 ). The digital / analog converter 4 and the output data of the digital / analog converter 4 for converting the digital signal into an analog signal and applying the same to the monomulti 2 are stored. Automatic head switching control device, characterized in that consisting of the ypyrom (5) to hold. 안정시간측정용 타이머A를 클리어시킨 후 조정스위치를 누르면 헤드 스위칭조정 모드임을 표시하고, 스위칭신호용 주파수 인터럽트(I2)를 인에이블시켜 입력이 있으며 지연시타간측정용 타이머A를 클리어 및 시작하여 수직동기신호 인터럽트(I1)를 인에이블시키며, 그 인터럽트(I1)가 발생하면 상기 타이머A를 정지하여 상기 인터럽트(I1)(I2)를 디스에이블시킨 후, 상기 타이머A를 읽어 이 데이타가 417㎲ec 보다 크면 디지탈/아날로그 변환기(4)의 출력을 증가시키고 407㎲ec 이하이면 그 디지탈/아날로그변환기(4)의 출력을 감소시키고, 안정시간측정용 카운터A를 클리어시키고 일정시간을 지연시킨 다음 상기 반복 수행하며, 상기 스위칭 신호용주파수(SW30Hz)와 수직동기신호(V.S)간의 간격이 일정횟수 이상이면 완료시키는데 조정표시가 온되어 있으면 상기 디지탈/아날로그 변환기(4)의 데이타를 이이피롬(5)에 저장되게 하는 것을 특징으로 하는 자동 헤드 스위칭 제어방식.Pressing the adjustment switch after clearing the stable time measurement timer A indicates the head switching adjustment mode and enables the switching signal frequency interrupt (I 2 ) to input and clears and starts the delay time measurement timer A. Synchronization signal interrupt I 1 is enabled, and when interrupt I 1 occurs, the timer A is stopped and the interrupt I 1 (I 2 ) is disabled. Is greater than 417㎲ec, increases the output of the digital / analog converter 4, and if it is less than or equal to 407㎲ec, decreases the output of the digital / analog converter 4, clears the stable time counter A, and delays the fixed time. If the interval between the switching signal frequency (SW30Hz) and the vertical synchronizing signal (VS) is more than a certain number of times, the adjustment is turned on. Automatic head switching control method, characterized in that the data of the digital / analog converter (4) is stored in the Epyrom (5). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
