본 고안은 VCR의 임피던스 로울러에 관한 것으로, 특히 테이프를 일정하게 주행시킬 수 있도록 한 VCR의 임피던스 로울러에 관한 것이다.The present invention relates to an impedance roller of a VCR, and more particularly, to an impedance roller of a VCR capable of constantly running a tape.

일반적으로 VCR의 주행계는 제1도 및 제2도에서 보인 바와같이, 공급릴(1)로 부터 나온 테이프(2)가 공급측 임피던스 로울러(3), 소거헤드(4), 안내로울러(5) 및 경사로울러(6)를 지나 드럼(7)에 공급되고 여기에서 출구측 경사로울러(8), 안내로울러(9), 권취측 임피던스 로울러(10)들을 지나 권취릴(11)에 권취될 수 있게 되어 있다.In general, the traveling system of the VCR has a tape (2) coming from the supply reel (1), the supply side impedance roller (3), the erasing head (4), the guide roller (5) as shown in FIGS. And to be supplied to the drum 7 via the inclined roller 6, where it can be wound around the outlet inclined roller 8, the guide roller 9, the wound side impedance roller 10, and wound on the winding reel 11. It is.

테이프(2)를 안정되게 주행시키기 위해서는 테이프(2)의 상하측이 상기 안내부재에 의하여 안내되어야 하는바, 상부 안내부재로서는 공급측 임피던스 로울러(3), 드럼(7)등이다. 그러나 이러한 안내역할부담은 테이프(2)의 유연성 때문에 강제성을 부여하기 어렵다. 따라서 주행계 조정에서 적합한 역할을 하도록 조정하기가 매우 어렵다. 그러나 임피던스 로울러(3)는 테이프의 진동을 흡수하는 중요한 기능을 갖지만 여기에서 테이프의 자율적인 방향성을 부여할 수가 있다.In order to stably run the tape 2, the upper and lower sides of the tape 2 must be guided by the guide member. The upper guide member is a supply side impedance roller 3, a drum 7 and the like. However, this guide role burden is difficult to impose due to the flexibility of the tape (2). Therefore, it is very difficult to adjust to play an appropriate role in the odometer adjustment. However, the impedance roller 3 has an important function of absorbing the vibration of the tape, but can give the tape autonomous directionality.

즉 종래에는 제3a도, 제3b에서 보인 바와같이 임피던스 로울러(3)의 상하직경을 동일하게 한 것이 있으나 방향성이 없으므로 제3c도에서 보인 바와같이 하측의 직경을 상측의 직경보다 크게 하므로서 방향성이 있도록 하였다. 그러나 이와같이 방향성을 부여하고자 하였으나 이는 테이프 주행시 하측방향으로 이동하려는 힘이 생겨 테이프에 비틀림이 발생한다.That is, in the prior art, the upper and lower diameters of the impedance roller 3 are the same as shown in FIGS. 3A and 3B, but since there is no directivity, the lower diameter is larger than the upper diameter as shown in FIG. It was. However, the directionality is intended to be provided in this way, but this causes a force to move downward when the tape travels, causing torsion in the tape.

본 고안에 있어서 종래의 이와같은 점을 감안하여 테이프 주행시 방향시 방향성이 있으나 테이프의 비틀림이 없도록 한 것인바, 이를 제4도에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention in consideration of such a conventional point in the direction of the tape running in the direction of the tape is not to be twisted, this will be described in more detail based on FIG.

하부스토퍼(31)에 결합되는 직경이 일정한 원통형의 임피던스 로울러(32)에 있어서, 로울러(32)의 주면에 시계반대 방향으로 나선형홈(32)을 형성하여서 된 구조이다.In the cylindrical impedance roller 32 having a constant diameter coupled to the lower stopper 31, the helical groove 32 is formed on the main surface of the roller 32 in the counterclockwise direction.

이와같은 본 고안은 이에 테이프가 접하여 주행시에 테이프와 임피던스 로울러(32) 사이에 나선형 홈(33)에 의한 에어갭이 형성되고 이 에어갭이 테이프를 하측으로 이동시키는 작용을 하게 된다.The present invention is such that the tape is in contact with the air gap formed by the spiral groove 33 between the tape and the impedance roller 32 at the time of running, the air gap is to act to move the tape downward.

이때 테이프는 하부스토퍼(31)에 의하여 하측방향의 이동이 제한되어 일정한 테이프 주행이 유지될 수 있다. 그리고 역주행시에는 테이프가 이 로울러(32)에서 떨어져 주행하므로 이 로울러(32)에 의하여 영향받지 않는다.At this time, the tape is restricted by the lower stopper 31 in the downward movement to maintain a constant tape running. In the reverse driving, the tape travels away from the roller 32 and thus is not affected by the roller 32.
