본 고안은 V.C.R(Video Cassette Recorder)에 관한 것으로, 특히 공급 릴(Reel)에 일방향의 회전 모멘트를 작용시켜 공급 릴로부터 풀려나오는 테이프의 텐션(Tension)을 조절하기 위한 텐션 조절기구에 관한 것이다.The present invention relates to a video cassette recorder (V.C.R), and more particularly, to a tension adjusting mechanism for adjusting a tension of a tape released from a supply reel by applying a rotation moment in one direction to the supply reel.
V.C.R의 공급 릴 일측에는 텐션암이 스프링으로 탄력설치되어 있고 공급 릴레는 밴드가 결합되어 이 밴드가 공급 릴의 외경면에 접속하고 있으며, 밴드의 일측 끝부분은 텐션암에 연결되어 있다.On one side of the V.C.R feed reel, the tension arm is elastically installed with a spring, and the supply reel is coupled to the band so that the band is connected to the outer diameter of the supply reel, and one end of the band is connected to the tension arm.
따라서 밴드는 스프링의 힘에 의해 항상 일방향으로 당겨지는 힘을 받게 되고 이 힘이 공급 릴의 브레이크력으로 작용하여 테이프는 적절한 장력을 가진 상태로 풀린다.Therefore, the band is always pulled in one direction by the force of the spring, which acts as the brake force of the supply reel, and the tape is released with the proper tension.
상기와 같은 V.C.R의 텐션 조절기구에 사용되어온 종래의 밴드. 예를 들어제6도에 도시한 바와 같은 밴드는 대략 U자형으로 된 밴드본체(21)의 내측면에 마찰부재(22)를 부착하고 밴드본체(21)의 양측 끝부분에는 후크부(24)가 일체형으로 형성된 제1밴드홀더(23)와 장공(26)이 있는 제2밴드홀더(25)를 결합한 구조로 되어 있다.The conventional band has been used in the tension control mechanism of the V.C.R as described above. For example, the band as shown in FIG. 6 attaches a friction member 22 to the inner side of the band body 21 having a substantially U shape, and hooks 24 at both ends of the band body 21. Has a structure in which the first band holder 23 formed integrally with the second band holder 25 having the long hole 26 is combined.
또 상기한 밴드는 조립시 제1밴드홀더(23)에 형성된 후크(24)에 의해 제1밴드홀더(23)가 텐션암에 결합되고 장공(26)으로 삽입되는 스크류에 의해 제2밴드홀더(25)가 메인 베이스에 고정되며, 마찰부재(22)는 공급 릴의 외경면과 탄력적으로 접속하면서 공금 릴에 브레이크력을 작용시킨다.In addition, when the band is assembled, the first band holder 23 is coupled to the tension arm by a hook 24 formed in the first band holder 23, and the second band holder is inserted into the long hole 26 by the screw. 25) is fixed to the main base, the friction member 22 is applied to the reel and the brake force while elastically connected to the outer diameter surface of the supply reel.
그러나 상기한 바와 같은 종래의 장치는 밴드가 밴드본체(21)와 2개의 밴드홀더(23)(25)를 분할 형성된 후 조립이 되는 구조이기 때문에 부품수가 많아지고 조립공수가 많아지며, 또한 밴드본체(21)와 밴드홀더(23)(25)의 결합을 위해 밴드홀드에 돌기(27)를 형성하여 이 돌기를 밴드본체(21)의 구멍(28)에 끼운 후 스토퍼(29)를 이용하여 결합하여야 함에 따라 조립 작업이 힘들고 돌기와 구멍의 칫수관리가 어려운 결점도 있다.However, the conventional apparatus as described above has a structure in which the band is assembled after the band body 21 and the two band holders 23 and 25 are separately formed, so that the number of parts increases and the number of assembly operations increases, and also the band body ( 21) and the band holders 23, 25 to form a projection 27 in the band holder for coupling the projections to the hole 28 of the band body 21, and then must be combined using a stopper (29). This makes it difficult to assemble and difficult to manage the projections and holes.
본 고안은 밴드본체와 밴드홀더가 각각 분리제작된 후 조립되는 종래의 구조와는 달리 밴드본체와 밴드홀더가 일체형으로 형성된 텐션 조절기구를 제공하기 위한 것인 바, 이를 첨부도면 제1도 내지 제5도를 참조하여 더욱 상세하게 설명하면 다음과 같다.The present invention is to provide a tension adjusting mechanism in which the band body and the band holder is formed integrally, unlike the conventional structure in which the band body and the band holder are separately manufactured and then assembled. Referring to Figure 5 in more detail as follows.
첨부도면 제1도와 제2도는 본 고안의 사시도와 평면도로서 본 고안의 텐션조절기구는 텐션암(10)과 밴드(1) 그리고 밴드에 항상 일방향의 힘을 작용시키는 스프링(11)으로 구성된다.1 and 2 are a perspective view and a plan view of the present invention, the tension adjusting mechanism of the present invention is composed of a tension arm 10 and the band (1) and the spring 11 to always apply a force in one direction to the band.
밴드(1)는 U자형으로 된 밴드본체(2)와 이 밴드본체의 내측면에 부착된 마찰부재(3), 그리고 밴드본체의 양 끝단부에 일체형으로 형성된 제1밴드홀더(4)와 제2밴드홀더(6)로 구성되며, 제2밴드홀더(4)에는 후크(5)가 일체로 형성되어 있고 제2밴드홀더(6)에는 장공(7)이 형성되어 있다.The band 1 includes a U-shaped band main body 2, a friction member 3 attached to the inner surface of the band main body, and first band holders 4 formed integrally with both ends of the band main body, and It consists of a two-band holder (6), the hook 2 is formed integrally with the second band holder (4) and the long hole (7) is formed in the second band holder (6).
또한 제1밴드홀더(4)는 후크(5)에 의해 텐션암(10)에 회전가능한 상태로 결합되고, 제2밴드홀더(4)는 스크류에 의해 메인 베이스에 고정되며, 마찰부재(3)는 공급 릴(12)의 외경면에 접속된다.In addition, the first band holder (4) is rotatably coupled to the tension arm (10) by a hook (5), the second band holder (4) is fixed to the main base by a screw, the friction member (3) Is connected to the outer diameter surface of the supply reel 12.
제3도는 마찰부재(3)가 공급 릴(12)에 접속된 상태를 나타낸 단면도이다.3 is a cross-sectional view showing a state in which the friction member 3 is connected to the supply reel 12.
제4도는 밴드의 일부 평면도로서, 밴드에는 밴드폭(t1)보다 좁은 폭(t2)을 가진 얇은 두께의 연결부(8)가 1개소 이상 형성되어 밴드의 굽힙성을 양호하게 하여 준다.4 is a partial plan view of the band, in which at least one connection portion 8 having a thin thickness t 2 , which is narrower than the band width t 1 , is formed in the band, thereby improving the bendability of the band.
제5도는 밴드본체(2)가 밴드가이더(13)에 결합된 상태를 나타낸 단면도로서, 밴드의 일측에는 가이드홈을 가진 밴드가이더(13)가 설치되어 있고 밴드본체(2)에는 가이드홈에 끼워지는 가이드돌기(9)가 형성되어 있다.5 is a cross-sectional view showing a state in which the band body 2 is coupled to the band guider 13, and a band guider 13 having a guide groove is installed at one side of the band, and the band body 2 is fitted into the guide groove. The losing guide protrusion 9 is formed.
따라서 밴드본체(2)는 밴더가이더(13)에 의해 상, 하의 유동이 규제된다.Therefore, the band body 2 is controlled by the vender guider 13, the flow of the upper and lower.
이와 같이 본 고안은 밴드본체(2)와 양측 밴드홀더(4)(6)가 일체형으로 형성되어 있으므로 부품수가 대폭 감소되고 조립공수가 줄어들어 생산성의 향상을 가져오게 된다.As such, the present invention has a band body 2 and both side band holders (4) and (6) are integrally formed so that the number of parts is greatly reduced and the number of assembly operations is reduced, thereby improving productivity.
또한 밴드본체(2)에 얇은 두께의 연결부(8)가 형성되어 마찰부재(3)와 공급 릴의 접촉력을 향상시킬 수 있게 되므로 텐션 조절작동이 더욱 확실해지며, 밴드의 높이 규제가 가능해지는 등의 효과가 있다.In addition, a thinner connection portion 8 is formed on the band body 2, so that the contact force between the friction member 3 and the supply reel can be improved, so that the tension adjusting operation becomes more certain, and the height of the band can be regulated. It works.
