Abstract

본 발명은 VCR의 테이프 손상 방지방법에 관한 것으로, 테이프를 삽입하고 키패드의 재생동작 모드를 선택하여 캡스턴 모터가 회전하게되면 일측 릴이 회전함과 동시에 타측 릴의 릴펄스를 감지하여 타측 릴이 회전하지 않을 경우에는 캡스턴 모터를 정지시키고, 상기 캡스턴 모터축과 압착되어 있는 핀치 로울러를 압착 분리한 후 상기 캡스턴 모터를 역회전하여 상기 일측 릴을 역회전시킴으로써, 타측 릴이 회전하지 않음으로 인하여 풀린 테이프를 상기 일측 릴에 되감도록한 후, 한 모드를 정지모드로 전환되도록 함으로서 정지 모드에서 다른 모드의 동작 수행시 발생할 수도 있는 테이프의 엉킴이나 씹힘을 방지하고자 한 것이다.The present invention relates to a method of preventing tape damage of a VCR. When a capstan motor is rotated by inserting a tape and selecting a regeneration operation mode of a keypad, one reel rotates and the other reel rotates by sensing a reel pulse of the other reel. If not, the capstan motor is stopped, and the pinch roller that is pressed against the capstan motor shaft is crimped and separated. Then, the capstan motor is rotated in reverse to rotate the one side reel so that the other reel does not rotate. After rewinding to one side of the reel, by switching to one mode to the stop mode to prevent tangling or chewing of the tape that may occur when performing the operation of the other mode in the stop mode.

Claims (2)

VCR의 데크가 재생동작 모드인가를 판단하는 단계와, 재생동작 모드이면 푸는 쪽의 릴이 회전함에 따라 감는 쪽의 릴의 회전유무를 검출하는 단계와, 감는 쪽의 릴이 회전하는지 판단하는 단계와, 회전하면 상기한 두 번째 단계로 진행하는 단계와, 소정의 시간동안 회전하지 않으면 다음 단계로 진행하여 핀치 로울러의 테이프 압착을 해제하는 단계와, 소정의 시간동안 푸는 쪽의 릴을 역회전하는 단계와, 정지하는 단계로 구성하여서 됨을 특징으로 하는 VCR의 테이프 손상 방지방법.Determining whether the deck of the VCR is in the regeneration mode; detecting the reel of the winding side as the reel on the unwinding side rotates; and determining whether the reel on the winding side rotates. , If it rotates, proceeds to the second step; if it does not rotate for a predetermined time, proceeds to the next step to release the tape compression of the pinch roller; and reversely rotates the reel on the unwinding side for a predetermined time. And a step of stopping the tape damage of the VCR. 제1항에 있어서, 릴의 회전 및 회전방향은 캡스턴 모터에 의해서 결정됨을 특징으로 하는 VCR의 테이프 손상 방지방법.The method of claim 1, wherein the reel's rotation and rotation direction are determined by a capstan motor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
