Abstract

본 발명은 VCR의 테이프 씹힘 방지방법에 관한 것으로써, 캡스턴 모터가 회전함에 따라 릴디스크가 회전하게 되면 릴센서는 릴디스크의 회전을 감지하게 되고 이 감지신호를 마이크로 프로세서는 입력받아 로딩모터가 동작하도록 서봉 제어신호를 출력하도록 함으로써 캡스턴 모터가 동작할 경우에만 로딩모터가 동작되도록 하여 종래에서 처럼 캡스턴 모터의 동작에 관계없이 로딩동작이 이루어짐에 따라 풀린만큼의 테이프가 이젝트 되는 중 테이프에 손상이 발생되는 것을 방지할 수 있도록 하기 위한 것이다.The present invention relates to a method of preventing tape chewing of a VCR. When the reel disk rotates as the capstan motor rotates, the reel sensor detects the rotation of the reel disk and the microprocessor receives the detection signal to operate the loading motor. When the capstan motor is operated, the loading motor is operated only when the capstan motor is operated. Thus, as the loading operation is performed regardless of the operation of the capstan motor as in the prior art, damage is caused to the tape while the released tape is ejected. This is to prevent it from happening.

Claims (1)

VCR의 테이프 씹힘 방지방법에 있어서, 테이프를 삽입한 후 카세트 홀더에 테이프가 안착되면 언로딩 표지션 상태를 유지하는 단계와, 언도링 포지션 상태에서 소정시간 동안 릴펄스를 체크하기 위해 빨리감기(FF)신호를 서보(6)로 출력하는 단계와, 캡스턴 모터(4)의 회전여부에 따라 마이크로 프로세서(3)는 릴센서(7)로부터의 입력신호의 유무를 확인하는 단계와, 릴센서(7)로 부터 입력신호가 있을 경우에는 마이크로 프로세서(3)은 소정의 시간동안 서보(6)로 되감기(REW)신호를 출력하는 단계와; 테이프가 초기의 상태로 되감기(REW)된 상태에서 풀베이스 로딩이 이루어지도록 서보(6)로 로딩모터(5) 구동신호를 출력하는 단계와, 입력신호가 없을 경우에는 마이크로 프로세서(3)에서 이젝트 신호를 서보(6)로 출력하여 언로딩 포지션 상태에서 테이프가 이젝트 되도록 하는 단계들에 의해 동작됨을 특징으로 하는 VCR의 테이프 씹힘 방지방법.In the method of preventing tape chewing of a VCR, after the tape is inserted, the tape holder is placed in the cassette holder to maintain the unloading position and fast forward to check the reel pulse for a predetermined time in the undoing position. Outputting the signal to the servo (6), and depending on whether the capstan motor (4) rotates, the microprocessor (3) checks the presence or absence of an input signal from the reel sensor (7), and the reel sensor (7). Outputting a rewind (REW) signal to the servo 6 for a predetermined time when there is an input signal from the microprocessor 3; Outputting the driving motor 5 driving signal to the servo 6 so that the full base loading is performed in the state where the tape has been rewound (REW) to the initial state, and if there is no input signal, the microprocessor 3 ejects the driving signal. Outputting a signal to the servo (6) to cause the tape to be ejected in the unloading position state. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
