본 고안은 VTR에서 테이프의 적절한 텐션을 유지시키는 텐션암의 동작상의 신뢰성과 구조적 간단화를 이루려는 텐션암에 관한 것이다.The present invention relates to a tension arm to achieve operational reliability and structural simplicity of the tension arm in maintaining a proper tension of the tape in the VTR.

VTR에서 텐션암에 관련된 주변 구조는 제2도와 같다. 즉, 텐션암(2)과 텐션 밴드(3) 이동단 브라켓(10)을 힌지(9)로 고정하고, 테이프 장력 변화시 텐션암(2)이 힌지(11)를 중심으로 좌우 회전 함에 따라 텐션밴드(3) 이동단 브라켓(10)이 좌우로 이동한다.The peripheral structure related to the tension arm in the VTR is shown in FIG. That is, the tension arm (2) and the tension band (3) moving end bracket (10) is fixed by the hinge (9), and the tension arm (2) is rotated around the hinge (11) around the hinge (11) when the tape tension changes The band 3 moving end bracket 10 moves left and right.

텐션밴드(3)이동단 브라켓(10)이 움직임에 따라 텐션밴드(3)가 릴테이블(4)에 걸리는 마찰제동력을 변화시켜 테이프의 장력을 조절하는 것이다.As the tension band 3 moves at the end of the bracket 10, the tension band 3 changes the friction braking force applied to the reel table 4 to adjust the tension of the tape.

이러한 종래의 VTR의 텐션암 장치에 있어서는 텐션암(2)의 움직임을 텐션밴드(3) 이동단의 움직임으로 정확히 바꾸어 주어야 하는데, 텐션암(2)과 텐션밴드(3)이동단 브라켓(10)을 힌지(9)에 의해 연결하여 텐션밴드(3) 이동단브라켓(10)이 회전을 일으키면서 텐션암(2)의 움직임을 텐션밴드(3)에 전달 하므로 운동전달의 정확성과 재현성이 문제가 되고 운동전달이 원활치 못하게 된다는 단점이 있었던 것이다.In the conventional tension arm device of the VTR, the movement of the tension arm (2) should be accurately changed to the movement of the tension band (3) moving end, the tension arm (2) and the tension band (3) moving end bracket (10) Is connected by the hinge (9) and the tension band (3) mobile end bracket (10) rotates to transfer the movement of the tension arm (2) to the tension band (3), so the accuracy and reproducibility of the movement transmission is problematic There was a disadvantage that the movement is not smooth.

본 고안은 종래의 이러한 단점을 해소 하고자 안출한 것인데 이는 릴테이블과 텐션암 및 제동을 위한 밴드와의 관계에서 이동단 브라켓을 텐션암에서 제거 하는 대신 원부호를 형성시킨 원호휠부로 하므로써 이들의 동작 관계에서의 신뢰성과 구조를 간단히 할 수 있는 이점을 부여할 목적이 있는 것이다.The present invention has been devised to solve these disadvantages of the related art, which is operated by using circular arcs instead of removing the end brackets from the tension arm in relation to the reel table, tension arm and braking band. The purpose is to give the advantage of simplifying the structure and reliability in the relationship.

이하에서 이를 상세히 설명하면 다음과 같다.This will be described in detail below.

텐션암 밴드(3), 릴테이블(4), 고정구(5), 스프링(6)으로 구성된 것에 있어서, 상기 텐션암의 이동브라켓 대신 이 부위에 원호휠부(1)를 형성시키고, 이의 일단에 밴드(3)를 고정시켜서 된 것이다.In the tension arm band (3), the reel table (4), the fixture (5), the spring (6), instead of the movement bracket of the tension arm to form an arc wheel portion (1) in this area, and one end of the band It was made by fixing (3).

이러한 구성의 본 고안은 텐션암(2)이 움직일때 텐션 밴드(3)는 원호휠부(1)의 원호접면에 일부는 감기고 나머지는 접선 방향으로 걸려서 테이프의 장력이 변화하여 텐션암(2)이 좌우로 회전 하여도 텐션밴드(3)는 항상 같은 모양으로 걸려 있게 되는 것이다.The present invention of such a configuration is that when the tension arm (2) is moved, the tension band (3) is wound around the arc contact surface of the arc wheel portion (1) and the other part is caught in the tangential direction so that the tension of the tape changes the tension arm (2) Even if it rotates to the left and right, the tension band (3) is always hanging in the same shape.

그러므로, 텐션암(2)의 움직임이 텐션밴드(3)의 움직임으로 정확하고 원 활하게 전달된다.Therefore, the movement of the tension arm 2 is transmitted accurately and smoothly to the movement of the tension band 3.

이러한 본 고안은 VTR에서 텐션암과 밴드를 이용한 테이프 텐션 조절 장치에 있어서 텐션암의 구조를 변형한 간단한 구성으로 동작상의 신뢰성을 얻을 수 있는 유익한 특징이 있는 것이다.This invention has a beneficial feature that can obtain operational reliability with a simple configuration of the structure of the tension arm in the tape tension control device using the tension arm and the band in the VTR.
