본 고안은 자기기록 재생장치의 릴의 백텐션 구조체에 관한 것으로, 특히 회전면의 마찰력을 최소화 하기 위해 폴리와셔를 사용한 릴의 백텐션 구조체에 관한 것이다.The present invention relates to a back tension structure of a reel of a magnetic recording and reproducing apparatus, and more particularly, to a back tension structure of a reel using a polywasher to minimize frictional force of a rotating surface.
일반적으로 자기 테이프를 기록매체로 하여 신호의 기록 및 재생을 실행하는 자기기록 및 재생장치에서는 기록 또는 재생시에 테이프 카세트에서 자기 테이프를 인출하여 이것을 자기헤드를 내장한 회전 실린더의 주위에 감는 것에 의해 테이프 주행로를 형성하고, 또 기록 또는 재생의 종료시에는 테이프를 테이프 주행로에서 인출시켜서 카세트에 수납시키는 테이프 로딩기구가 사용되고 있다.In general, in a magnetic recording and reproducing apparatus for recording and reproducing a signal using a magnetic tape as a recording medium, a magnetic tape is taken out of a tape cassette during recording or reproduction, and the tape is wound around a rotating cylinder having a magnetic head. A tape loading mechanism is used in which a running path is formed and at the end of recording or reproduction, the tape is taken out of the tape running path and stored in a cassette.
따라서, 기록이나 재생시에는 캡스턴이 회전하는 것에 의해 자기 테이프가 공급릴에서 인출되어 감기릴에서 감겨지도록 주행하고, 회전 실린더가 회전해서 이것에 탑재되어 있는 여러개의 자기 헤드가 자기 테이프를 주사한다.Therefore, during recording or playback, the capstan rotates so that the magnetic tape is drawn out of the supply reel and wound around the winding reel, and the rotating cylinder rotates to scan the magnetic tape mounted on the magnetic head.
이때, 인장핀에 의해서 자기 테이프의 인장이 검지되고, 이 검지결과에 따라서 공급릴의 릴 베이스의 브레이크등이 제어되어 자기 테이프의 인장이 일정하게 유지된다.At this time, the tension of the magnetic tape is detected by the tension pin, and according to the detection result, the brake of the reel base of the supply reel is controlled and the tension of the magnetic tape is kept constant.
그러나, 종래의 기술에서는 백텐션 회전시 스프링이 칩릴과 고정되지 않아 원활한 회전이 이루어지지 않아 테이프의 주행이 단속되는 경우가 발생한다.However, in the related art, when the back tension is rotated, the spring is not fixed to the chip reel so that smooth rotation does not occur, and thus the driving of the tape is interrupted.
본 고안의 목적은 상술한 종래의 기술을 해소하기 위한 것으로 백텐션 회전시 스프링이 릴과 고정되어 회전면을 일정하게 하고, 회전면에서의 마찰력을 최소화할 수 있는 릴의 백텐션 구조체를 제공하는 것이다.An object of the present invention is to solve the above-described conventional technology to provide a back tension structure of the reel that the spring is fixed to the reel when the back tension rotation to make the rotation surface constant, and minimize the frictional force on the rotation surface.
상술한 목적을 달성하기 위해, 본 고안의 백텐션 구조체는 자기기록 재생장치의 릴에 있어서, 자기 테이프를 감거나 또는 공급하는 칩릴, 상기 칩릴을 회전시키는 릴대, 상기 릴대에 장착되고 데크동작을 가능하게 하는 메인샤시, 상기 칩릴에 직각 방향의 힘을 인가하고 상기 릴이 풀릴 때 인정한 하중을 인가하는 탄성부재와 상기 탄성부재와 상기 메인샤시 사이에 장착되고, 상기 탄성부재의 회전을 원활하게 하는 미끄럼면을 갖는 와셔부재를 구비하여 형성된다. 이와 같은 와셔부재를 사용하는 것에 의해 회전면의 마찰력을 최소화 할 수 있다.In order to achieve the above object, the back tension structure of the present invention is a reel of a magnetic recording and reproducing apparatus, comprising: a chip reel for winding or supplying a magnetic tape, a reel stand for rotating the chip reel, and mounted on the reel stand and capable of deck operation. The main chassis, which is applied between the elastic member and the main chassis and the elastic member for applying a force in the perpendicular direction to the chip reel and applying a recognized load when the reel is released, the sliding to smooth the rotation of the elastic member It is formed with a washer member having a face. By using such a washer member it is possible to minimize the friction of the rotating surface.
이하, 본 발명의 실시예를 도면에 따라 설명한다.Best Mode for Carrying Out the Invention Embodiments of the present invention will be described below with reference to the drawings.
제1도는 본체상에 장착된 릴대의 부분 확대도로서, (1)은 자기 테이프를 감거나 공급하는 칩릴, (2)는 릴에 직각 방향으로 힘을 인가하여 릴이 풀릴 때 일정한 하중을 인가하는 릴 스프링, (3)은 릴 스프링(2)의 회전을 원활하게 하는 미끄럼 면을 구비한 폴리와셔, (4)는 칩릴(1)을 회전시키는 릴대, (5)는 데크동작을 가능하게 하는 본체로서의 메인샤시이다.1 is a partially enlarged view of a reel mount mounted on a main body, (1) a chip reel for winding or supplying a magnetic tape, and (2) a force applied at right angles to the reel to apply a constant load when the reel is released. Reel spring, (3) is a poly washer having a sliding surface to facilitate the rotation of the reel spring (2), (4) a reel base for rotating the chip reel (1), (5) the main body to enable the deck operation It is the main chassis as.
제1도에서 알 수 있는 바와 같이, 폴리와셔(3)는 메인샤시(5)와 릴 스프링(2) 사이에서 백텐션 회전시 릴 스프링(2)이 칩릴(1)과 고정되게 하여 회전면이 일정하게 되도록 작용한다.As can be seen in FIG. 1, the polywasher 3 has a fixed rotational surface by allowing the reel spring 2 to be fixed to the chip reel 1 when the back tension is rotated between the main chassis 5 and the reel spring 2. To work.
이하, 제1도에 도시한 구조의 동작에 대해서 셜명한다. 백텐션시 도시하지 않은 카세트 테이프가 한쪽으로 데크의 릴(1)에 의해 회전하고 다른 한쪽은 카세트 테이프에 의해 끌려 같이 회전한다.Hereinafter, operations of the structure shown in FIG. 1 will be described. During back tension, a cassette tape (not shown) is rotated by the reel 1 of the deck to one side and dragged by the cassette tape to rotate the other.
이때, 같이 끌려 회전하는 쪽의 릴은 직각 방향의 힘을 받아 릴의 회전이 일정하도록 해야 한다. 이 경우, 본 고안에 있어서는 일정한 힘을 받도록 릴 스프링(2)이 칩릴(1) 쪽으로 힘을 인가하며 칩릴(1)과 같이 회전한다.At this time, the reel of the side to be pulled and rotated should be a constant rotation of the reel under the force of the right direction. In this case, in the present invention, the reel spring 2 applies a force toward the chip reel 1 so as to receive a constant force, and rotates together with the chip reel 1.
본 고안에 의해 마련된 폴리와셔(3)는 릴 스프링(2)이 일정한 힘을 줄 수 있도록 마찰을 최소화 한다. 상기 실시예에 있어서는 마찰을 최소화 하기 위해 폴리와셔를 사용하였지만, 이와 동등한 기능을 하는 것으로 대체가능한 것은 물론이다.The polywasher 3 provided by the present invention minimizes friction so that the reel spring 2 can give a constant force. In the above embodiment, a polywasher is used to minimize friction, but it is a matter of course that it can be replaced with a function equivalent thereto.
상술한 바와 같이, 본 고안에 의하면, 카세트 데크의 주요기능인 백텐션을 일정하게 하여 기본 성능인 와우/플러터의 성능을 향상시키고, 특히 테이프 끝단의 성능이 향상된다.As described above, according to the present invention, the back tension, which is the main function of the cassette deck, is made constant to improve the performance of the cochlear / flutter, which is the basic performance, and in particular, the performance of the tape end is improved.
