본 고안은 비데오 테이프 레코오더(VTR)의 테이프 주행시 핀치로울러와 테이크업 리일(Take-up Real) 중간의 테이프 처짐을 해결한 테이프 처짐방지에 관한 것으로, 단부에 포올(Pole)을 갖고 타단하부에는 약브레이크를 가진 포올아암(Pole Arm)을 공지의 핀치레버의 중심축에 장착하여 코일스프링에 의해 테이프의 바깥 방향으로 회동 탄발력을 갖도록 갖도록 한 것이다.The present invention relates to a tape sag prevention solution that solves a tape sag between a pinch roller and a take-up real while driving a tape of a video tape recorder (VTR), and has a pole at the end and a Pole arm having a weak brake is mounted on the central axis of a known pinch lever so as to have rotational resilience in the outward direction of the tape by a coil spring.

종래에는 테이프의 주행시 캡스턴축과 핀치로울로 사이를 거쳐서 테이크업 리일로 공급되는 테이프가 서프라이 리일과 테이크업 리일의 회전속도 또는 테이프의 장력의 차이에 의해 처짐현상이 발생하여도 이를 방지할 수 있는 효과적인 장치가 없었던 것이다.Conventionally, the tape supplied to the take-up rail between the capstan shaft and the pinch roller when the tape is running can be prevented even if the tape is drooped due to the difference in the rotational speed or the tension of the tape. There was no effective device.

본 고안은 테이크업 리일에는 약브레이크를 걸어주고 테이프주행시에는 핀치로울러와 테이크업 리일 사이에서 테이프의 장력을 조절할 수 있도록 하므로서 테이프의 처짐을 방지토록 고안된 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to prevent sagging of the tape by applying a weak brake to the take-up rail and adjusting the tension of the tape between the pinch roller and the take-up rail when the tape is being driven. same.

데이크업 리일(8)의 상부에 핀치로울러(10)를 가진 핀치로울러 아암(9)에 연동되게 착설된 핀치레버(6)가 중심축(7)을, 축으로 슬라이드판(11)의 작동에 따라 스프링(12)에 의해 회동되도록 구성된 공지한 주행장치에 있어서, 단부에 포올(2)을 갖고 하부에는 판스프링(4)에 의해 작동하는 약브레이크(3)를 가진 포올 아암(1)을 코일스프링(5)에 의해 항상 바깥쪽으로 회동되게끔 타단을 핀치레버(6)의 중심축(7)에 착설하여서 되는 비데오 테이프 레코오더의 테이프 처짐방지장치이다.A pinch lever 6 mounted in conjunction with a pinch roller arm 9 having a pinch roller 10 at the upper portion of the take-up rail 8 is used for the operation of the slide plate 11 around the central axis 7. In a known traveling device configured to be pivoted by a spring 12 accordingly, a pole arm 1 having a pole 2 at its end and a weak brake 3 operated by a leaf spring 4 at its lower end is coiled. It is a tape drooping prevention device of a video tape recorder, which is mounted on the central axis 7 of the pinch lever 6 so that it is always rotated outward by the spring 5.

첨부도면 중 미설명부호 13은 축봉, 14는 스토퍼, 15는 캡스턴축, 16은 테이프를 각각 나타낸다.In the accompanying drawings, reference numeral 13 denotes a shaft, 14 a stopper, 15 a capstan shaft, and 16 a tape.

본 고안은 포올아암(1)이 핀치레버(6)의 중심축(7)을 기점으로 코일스프링(5)의 장력에 의해 항상 테이프(16)의 바깥쪽으로 회동하려는 상태를 유지하게 되는데, 테이프(16)의 주행시 포올아암(1)의 포올(2)은 핀치로울러(10)와 테이크업 리일(8)사이에서 발생하는 테이프(16)의 장력에 의해 어느 정도 테이프 안쪽으로 회전된 상태를 유지하면서 포올아암(1)이 하부의 판스프링(4) 단부의 약브레이크(3)가 테이크업 리일(8)에 브레이크 역할을 하여 주므로서 테이크업 리일(8)의 급속한 회전을 어느 정도 제동시켜 주게 되는 것이다.The present invention is to maintain the state in which the pole arm (1) to always rotate to the outside of the tape 16 by the tension of the coil spring (5) from the central axis (7) of the pinch lever (6), While driving 16, the pole 2 of the pole arm 1 is maintained to some extent rotated inside the tape by the tension of the tape 16 generated between the pinch roller 10 and the take-up rail 8. The pawl arm 1 brakes the take-up rail 8 to some extent as the weak brake 3 at the lower end of the leaf spring 4 serves as a brake on the take-up rail 8. will be.

그러나 테이프(16)가 핀치로울러(10)와 테이크업 리일(8) 사이에서 처지게 되면, 포올아암(1)이 코일스프링(5)에 의해 테이프(16)의 바깥쪽으로 회동하므로서 테이크업 리일(8)에 가해지던 약브레이크(3)는 떨어지게 되므로 테이크업 리일(8)은 정상회전을 하면서 처짐상태의 테이프(16)를 급속히 감아주게 되는 것이다.However, if the tape 16 sags between the pinch roller 10 and the take-up rail 8, the pole arm 1 is rotated out of the tape 16 by the coil spring 5 so that the take-up rail ( Since the weak brake 3 applied to 8 is dropped, the take-up rail 8 rapidly winds the tape 16 in a deflection state while performing a normal rotation.

이와 같은 작동을 하는 본 고안은 간단한 구조와 작동으로서 핀치로울러(10)와 캡스턴축(15)을 통과한 테이프(16)가 테이크업 리일(8)과의 사이에서 처짐현상이 발생하는 것을 방지하므로서 테이프의 주행상태가 보다 양호하겠끔 하는 것이다.The present invention, which operates as described above, has a simple structure and operation to prevent the tape 16 passing through the pinch roller 10 and the capstan shaft 15 from sagging between the take-up rail 8. The running state of the tape will be better.
