Abstract

A spool hub for tape cartridges or cassettes, especially sound recording tape cartridges provided with slide or anti-friction foils, wherein the hub body is equiped with passageways or openings distributed at or over the circumference of the hub body. The passageways are advantageously located between blade0like webs. With this construction there is particularly reduced the friction between the spool and the slide or anti-friction foils, so that there prevail lower temperatures and there is acomplished a reduction of the undersired noise level.

Description

테이프 카트리지 또는 그와 유사한것에 사용되는 스풀허브(spool hub)Spool hubs used for tape cartridges or the like

제1도는 미끄럼박(foil)을 내장하고 있는 테이프 카트리지(tape cartridge) 또는 카세트.1 is a tape cartridge or cassette having a built-in foil.

제2도는 본 발명에 따른 스풀 허브의 투시도.2 is a perspective view of a spool hub according to the invention.

본 발명은 테이프 카트리지 또는 카세트 중에서 특히 미끄럼박 또는 반 저항막을 내장하고 있는 녹음테이프 카트리지에 사용되는 스풀 허브의 새롭고 개량된 구조에 관한 것이다.The present invention relates to a new and improved structure of a spool hub used in tape tape cartridges or cassettes, in particular tape tape cartridges having slip or semi-resistance films embedded therein.

지금까지 알려진 녹음테이프 카트리지 또는 카세트는 미끄럼박 또는 접촉하고 있는 박과 스풀 허브 사이의 마찰이 가능한한 작도록 요구되고 있다. 그러나 지금까지 알려진 구조로는 이러한 요구를 쉽게 충족시키지 못하였다. 전술한 형태의 카세트는 고속동작시에 바람직하지못한 잡음마저 발생하고 있다. 예를들어 테이프 감을때와 같은 고속동작중에는 온도상승도 있을 수 있는데 물론 이것은 바람직하지 못한 것이다. 예를 들어 풀리에칠렌박을 사용할 경우 고속으로 테이프를 감을때의 온도상승으로 말미암아 하우징에 녹아붙는 경우도 발생할 수 있다.The tape tape cartridges or cassettes known to date are required to have as little friction as possible between the sliding foil or the foil in contact with the spool hub. However, structures known to date have not easily met this need. Cassettes of the type described above also generate undesirable noise during high speed operation. There may also be a temperature rise during high speed operation, for example when winding a tape, which is of course undesirable. For example, the use of pulley ethylene foil may also cause melting of the housing due to a rise in temperature when the tape is wound at high speed.

따라서 본 발명의 목적은 전술한 결점을 제거하고 종래의 기술적인 구조의It is therefore an object of the present invention to obviate the aforementioned drawbacks and to provide a

본 발명의 또다른 특별한 목적은 어떠한 결점도 새로 발생함이 없이 전술한 불리한점을 거의 대부분 제거시키는 스풀 허브의 새롭고 개량된 구조를 제공하는데 있다.Another particular object of the present invention is to provide a new and improved structure of a spool hub which eliminates almost all of the above disadvantages without any new drawbacks.

그러나 본 발명의 더욱 중요한 목적은 구조와 모양이 보다 단순하고, 제조하기에 경제적이고, 특히 고속동작중에 있어서 열발생을 줄이는 그러한 스풀 허브의 새롭고 개량된 구조를 제공하고, 전술한 종래의 테이프 카세트의 결점을 결지에서볼때 보다 향상된 성능을 제공하는데 있다.A more important object of the present invention, however, is to provide a new and improved structure of such a spool hub which is simpler in structure and shape, more economical to manufacture, and which reduces heat generation, especially during high speed operation, The drawback is to provide better performance in terms of fault.

설명이 진행됨에 따라 곧 명백해지겠지만, 본 발명의 목적에 맞도록 개발된 스풀 허브는 몸체의 둘레에 배분적으로 배열된 통로 또는 개구를 가지고 있는 양상을 하고 있다. 이 통로들은 되도록 서로 같은 간격을 가지고 있으며, 구멍 또는 유사한 관통의 형태 또는 개구에 의해 형성되었다.As will become clear as the description proceeds, the spool hub developed for the purposes of the present invention has an aspect with passages or openings arranged distributively around the body. These passages are spaced equally from each other and formed by the shape or opening of a hole or similar penetration.

특히 유리한 구조는, 내측 허브 링(ring)과 외측 허브 링 사이에 나란히 배열된 다수의 날개 또는 스포우크(spoke) 모양의 웨브(web)가 있는 것이다. 이 구조의 허브는 통풍기의 외양을 갖게되므로, 날개모양의 소자와 그에 대응하는 통로를 가지는 다른 특별한 구조를 가지지 않고도, 본 발명의 구조에 의해 자동적으로 공기의 순환이 이루어지게 된다.A particularly advantageous structure is that there are a plurality of wings or spoke shaped webs arranged side by side between the inner hub ring and the outer hub ring. Since the hub of this structure has the appearance of a ventilator, air circulation is automatically made by the structure of the present invention, without having another wing structure having a wing-like element and a corresponding passage.

이러한 공기의 순환은 마찰에 대해서 작용하게 되므로 특히 허브와 미끄럼박 사이의 마찰이 현저히 감소하게 된다. 그리고 직접 접촉됨으로 해서 부분적으로 발This circulation of air acts on the friction, and in particular, the friction between the hub and the slippage is significantly reduced. And partly due to direct contact

공기의 순환 또는 공기의 회전은 가능한 어떠한 온도상승에 대해서도 마찬가지로 작용하므로, 전술한 결점들은 실제적으로 제거된다.Since the circulation of air or rotation of air acts on any possible temperature rise as well, the aforementioned drawbacks are practically eliminated.

본 발명에 의한 스풀 허브의 구조는 부수적인 이점을 갖게 되는데, 그것은 통로 또는 구멍들로 말미암아 스풀의 회전상태를 시각적으로 잘 알 수 있다는 것이다.The structure of the spool hub according to the present invention has a secondary advantage, which is visually well understood by the passage or holes.

다음의 자세한 설명을 참작하면 본 발명이 보다 잘 이해되며 전술한 목적이외의 목적에 대해서도 명백히 알 수 있게 될 것이다. 설명은 첨부된 도면을 참고할 것이다.In view of the following detailed description, the present invention will be better understood and will become apparent from the above objectives. The description will refer to the accompanying drawings.

제1도에 발명에 따른 테이프 카트리지 또는 카트리지 단면도를 보이고 있다. 카트리지 또는 카세트 필수적으로 하우징(1)과 하우징(1)안에 위치한 스풀 몸체 또는 허브(3)으로 구성되어 있다. 하우징(1)에는 각 테이프를(roll)의 중심에 투명한 부분(2)의 있고, 그 (2)안에는 자유롭게 회전할 수 있고 비교적 큰 움직임에도 벗어나지 않게 되어있는 스풀허브(3)가 있다. 마그넥틱 테이프(3')은 스풀 몸체 또는 허브(3)위에 보통의 방법에 의해 감겨져 있다.1 shows a tape cartridge or cartridge cross section according to the invention. The cartridge or cassette consists essentially of the housing 1 and the spool body or hub 3 located in the housing 1. The housing 1 has a spool hub 3 with a transparent part 2 in the center of each roll, in which it is freely rotatable and free from relatively large movements. The magnetic tape 3 'is wound by the usual method on the spool body or hub 3.

또한 하우징(1)에는 (4)의 곳에 개구 또는 통로가 있는 것을 볼수가 있는데, 그 안으로 구동허브가 맞물리게 되며 따라서 스풀허브(3)은 드라이브 캠(cam)(5) 또는 동등한 구조의 방법에 의해서 회전할 수 있게 되어 있다.It can also be seen that there is an opening or passage in the housing 1 in which the drive hub engages therein so that the spool hub 3 is driven by a drive cam 5 or an equivalent structure. It is possible to rotate.

하우징(1)의 벽면과 테이프가 감겨져 있는 스풀 허브 또는 스풀 몸체(3)의 사이에 각각 미끄럼박 또는 반저항막(6) 및 (7)이 놓여져 있다. (6) 및 (7)은 움직Sliding or anti-resistive films 6 and 7 are placed between the wall surface of the housing 1 and the spool hub or spool body 3 on which the tape is wound, respectively. (6) and (7) move

이미 전술한 바와같이 종래의 구조로는 마찰이 너무 많이 생기므로, 한편으로는 과도한 온도의 상승을 야기하고 또 한편으로는 바람직하지 못한 잡음의 발생을 야기하고 있다.As already mentioned above, too much friction occurs in the conventional structure, on the one hand, causing excessive temperature rise and on the other hand, the generation of undesirable noise.

본 발명의 특징에 의하면 스풀 몸체 또는 허브(3)은 테이프 카트리지 또는 카세트의 내부에 공기의 순환을 자동적으로 유발하는 다수의 통로 또는 개구(8)을 가지고 있다. 물론 통로(8)은 기체역학적인 견지에서 설계되므로 공기의 순환은 잘 이루어지게 된다. 통로 또는 개구(8)에 바람개비 모양의 웨브를 설치할 경우에는 최상의 환풍 효과가 얻어지게 된다.According to a feature of the invention the spool body or hub 3 has a number of passages or openings 8 which automatically cause circulation of air inside the tape cartridge or cassette. Of course, the passage 8 is designed from the point of view of aerodynamics, so that the circulation of air is good. When a pinwheel-shaped web is installed in the passage or opening 8, the best ventilation effect is obtained.

제2도는 현저한 결과가 기대어지는 특별한 설계에 의한 스풀 허브의 가능한 구조의 투시도이다. 스풀 허브는 내측 링(9)와 외측링(10)으로 구성되며, (9)와 (10)은 다수의 날개 또는 스포우크 모양의 웨브(11)에 방법으로 서로 굳게 연결되어 있다. 이 날개 또는 스포우군 모양의 웨브(11)은 테이프 카트리지 내부에서 매우 효과적인 공기의 순환을 유발하므로 전술한 유익한 효과를 얻을 수 있게된다.2 is a perspective view of a possible structure of a spool hub by a special design where significant results are expected. The spool hub is composed of an inner ring 9 and an outer ring 10, and 9 and 10 are firmly connected to each other by means of a plurality of wings or spoke shaped webs 11. This wing or spore group shaped web 11 causes a very effective circulation of air inside the tape cartridge, so that the above-described beneficial effects can be obtained.

단순한 구멍 또는 그와 유사한 형태의 통로 또는 개구를 사용했을 경우에도 역시 마찰을 감소시키는 공기의 순환을 조장한다는 사실이 발견되었다.It has been found that the use of simple holes or similarly shaped passageways or openings also promotes the circulation of air which reduces friction.

본 발명의 우선적 실시예를 도시하고 설명하였지만, 본 발명이 여기에만 한정되지 않고 다음의 청구범위 내에서 얼마든지 다양하게 구체화될 수 있다는 것을 명백히 이해하여야 한다.While the preferred embodiments of the invention have been illustrated and described, it should be clearly understood that the invention is not limited thereto but can be embodied in various ways within the scope of the following claims.
