Abstract
본 발명은 자기기록재생기의 텐션 조절 장치에 관한 것으로, 종래에는 VHS나, 특히 8㎜테이프를 사용하는 기기에서는 테이프의 두께가 가장 얇은 테이프가 10㎛이기 때문에 텐션비는 1 : 1.3∼1.4에서 사용함으로써 별다른 문제가 없었으나, 현재 디지털 브이씨알(DVCR)용 테이프는 두께가 7㎛이기 때문에 현재의 텐션비로서는 정확한 테이프의 텐션 조절이 어려운 문제가 있는 바, 텐션 암(13)을 탄지하는 텐션 스프링(16)의 지지점(16a)을 가변가능하도록 하여 테이프의 텐션 감소효과를 향상시키도록 한 본 발명을 제공하여 테이프의 텐션이 증가되는 것에 대한 억제효과를 현저하게 향상시킴으로써 테이프의 두께가 보다 얇아지는 디지털 브이씨알과 같은 정밀한 자기기록재생기에 효과적으로 적용할 수 있도록 한 것이다.The present invention relates to a tension control device of a magnetic recording and reproducing apparatus. In the conventional apparatus using a VHS or an 8 mm tape, the tension ratio is used at 1: 1.3 to 1.4 because the tape having the thinnest tape is 10 µm. By doing so, there was no problem, but the current digital CR tape (DVCR) tape has a thickness of 7 μm, so it is difficult to accurately adjust the tension of the tape at the current tension ratio, so that the tension spring supporting the tension arm 13 is supported. Provided the present invention which makes the support point 16a of (16) variable so as to improve the tension reducing effect of the tape, thereby significantly improving the suppression effect against the increased tension of the tape, thereby making the tape thinner. It can be effectively applied to a precision magnetic recording player such as digital VR.
