Abstract

본 발명은 비디오 카셋트 레코드의 작동시 공급릴 디스크에 감겨져 있는 테이프의 변경변화에 따른 테이프 백텐션(Back Tension)을 조절하기 위한 테이프 텐션조절장치에 관한 것이다. 공급릴 디스크에서만 텐션을 발생하는 종래 테이프 텐션조절장치는 테이프 주행시 변하는 공급릴 디스크에 감겨진 테이프 반경의 변화와 같이 텐션 변화폭이 큰 경우의 텐션조절이 어려우므로 본 발명은 테이프 주행경로에 위치한 롤러부분에 롤러브레이크와 핀치롤러를 추가로 구비함으로써 상기 공급릴 디스크와 롤러브레이크에서 동시에 텐션을 발생시켜 주행 전 과정동안 테이프에 일정한 텐션을 작용시켜 안정된 화질을 제공할 수 있으므로 고화질의 HD VCR 뿐만 아니라 테이프를 사용하는 모든 기록, 재생 매체에 유용하게 사용될 수 있다.The present invention relates to a tape tension control device for adjusting the tape back tension in accordance with the change of the tape wound on the supply reel disk during the operation of the video cassette record. Conventional tape tension control device that generates tension only in the supply reel disk is difficult to adjust the tension when the tension variation is large, such as the change in the radius of the tape wound on the supply reel disk that changes during the tape run, the present invention is a roller portion located in the tape running path The roller brake and the pinch roller are additionally provided at the same time to generate tension at the feed reel disk and roller brake at the same time, and to provide a stable image quality by applying a constant tension to the tape during the entire driving process. It can be usefully used for all recording and reproducing media.
