본 고안은 비디오 카세트에 있어서, 카세트가 데크에 안착되지 않은 상태에서 테이프의 릴이 임의로 회전하여 테이프 풀림으로 인한 테이프의 손상을 방지하기위해 설치하는 릴의 록킹(locking)장치에 관한 것으로서 특히, 서플라이릴의 록커와 테이크엎 릴의 록커의 눌림단부를 길게 연장시켜 서로 겹치도록하고 이들중 하나의 록커에만 스프링을 사용토록 개량한 고안이다.The present invention relates to a reel locking device installed in a video cassette in order to prevent the tape from being damaged due to tape unwinding by rotating the reel of the tape arbitrarily while the cassette is not seated on the deck. The retractor locker and take-up reel locker extends the pressing end of the locker so that they overlap each other, and one of these rockers is designed to use a spring.

일반적으로 비디오 카세트의 릴 록킹 장치는 릴 각각에 해당하는 록커 2개가 사용되고 이들의 록킹을 해제하는 공통의 릴리이즈편이 구성된다.In general, two lockers corresponding to each reel are used as a reel locking device of a video cassette, and a common release piece for releasing their locking is configured.

이들 록커에는 록킹과 록킹해제의 원만한 동작을 위해 탄성을 부여하게되는데 종래에는 제 3 도와 같이, 록커(20)(20')의 눌림편(23)(23')의 단부가 서로 떨어져서 릴리이즈편(28)의 누르개(29)에 각기 인접된 것이므로 록커(20)(20')각각에 스프링(30)(30')을 걸어주었던것이다.These lockers are provided with elasticity for smooth operation of locking and unlocking. Conventionally, as in the third degree, the ends of the pressing pieces 23, 23 'of the lockers 20, 20' are separated from each other and the release piece ( 28 is a spring (30, 30 ') to each of the lockers (20, 20') because they are adjacent to each other.

따라서 종래에는 2개의 스프링 사용으로 인한 원가상승과 조립성 또는 좋지 못한 결점을 지녔던 것이다.Therefore, in the related art, the cost and the assembly or poor defects due to the use of two springs.

한편, 또 다른 종래에는 록커 몸체에 스프링편을 일체로 형성하여 원가절감을 꾀하였던 예도 있었으나 이는 수지제 스프링편이 주위온도 또는 반복사용 따른 탄성의 변화를 가져올수 있는 것이므로 바람직하지 못한 것이었다.On the other hand, in the prior art there was an example in which the spring piece is integrally formed on the rocker body to reduce the cost, but this is not preferable because the resin spring piece may bring about changes in elasticity due to ambient temperature or repeated use.

그러나 본 고안은 기존에 2개 사용했던 스프링을 한개로도 완전한 동작을 행할수 있도록 록커를 개량하고 그럼으로서 원가절감, 조립성향상을 기여하는데 의의를 갖는다. 그러면 본 고안의 구체예가 도시된 제 1 도와 제 2 도를 참조하면서 더욱 상세하게 설명하면 다음과 같다.However, the present invention is meaningful in that it improves the locker to perform a complete operation with one spring used in the past, thereby contributing to cost reduction and assembly improvement. Then, the embodiment of the present invention will be described in more detail with reference to FIGS. 1 and 2 as follows.

먼저 본 고안 장치에 적용될 개량된 록커에 대하여 설명하면 제 1 도와 같이, 원통형 록커몸체(1)(1')측방으로는 공지된 릴의 걸림편(2)(2')이 형성되고, 이와 소정각도록 뻗은 눌림편(3)(3')이 형성되며, 눌림편(3)(3')끈에는 눌림단부(4)(4')가 종래보다 더 연장되어 서로 겹칠수 있게된 것이다.First, the improved rocker to be applied to the device of the present invention will be described. As shown in the first diagram, the locking piece 2 (2 ') of the known reel is formed on the side of the cylindrical rocker body (1) (1'). Pressing pieces (3) (3 ') are formed to extend to each other, the pressing piece (3) (3') is a pressing end (4) (4 ') is extended more than the conventional can overlap each other.

제 2 도에 의하면 상기 눌림단부(4)(4')를 갖는 록커는 통상과 같이 각각의 지지봉(5)(5')에 끼워져 그들의 걸림편(2)(2')이 릴(6)(6')의 요철부(7)(7')로 출입가능하며, 서로 겹쳐진 눌림부(4)(4')중 바깥쪽의 눌림단부(4)가 공지된 릴리이즈편(8)의 누르개(9)에 직접 접촉케하되 한개의 스프링(10)은 안쪽의 누름단부(4')를 갖는 록커몸체(1')의 지지봉(5')상단부에 설치하여 본고안 장치를 이룬다.According to FIG. 2, the rockers having the pushed ends 4, 4 'are fitted to the respective supporting rods 5, 5' as usual, so that their engaging pieces 2, 2 'are reel 6 ( 6 ') of the release piece 8, which is accessible from the uneven portions 7 and 7', and which has an outer pressing end 4 of the pressed portions 4 and 4 'overlapped with each other. Direct contact with the spring 10 is installed on the upper end of the support rod (5 ') of the rocker body (1') having an inner pressing end (4 ') to form a safety device.

미설명부호 11은 스프링받침봉이다.Reference numeral 11 is a spring bearing rod.

이와같은 본고안 장치의 록킹상태와 록킹해제 상태는 제 2a, b 도에 도시되어 있다.The locked state and unlocked state of this inventive device are shown in Figs. 2a and b.

제 2a 도는 록킹상태이다. 다시말해서 카세트가 데크(도시생략)에 안착되지 않은 즉 초기 상태에며 이 상태에서는 양측 릴(6)(6')의 요철부(7)(7')가 각각 걸림편(2)(2')끝에 걸리어 한 방향(테이프가 풀리는 방향)으로 임의회전이 불가능하게된다.2a is in a locked state. In other words, the cassette is not seated on the deck (not shown), i.e., in the initial state, in which the uneven portions 7, 7 'of both reels 6, 6' are engaged with the catching pieces 2, 2 ', respectively. It is caught at the end, and arbitrary rotation is impossible in one direction (the direction of tape release).

반대로 카세트가 테크에 안착되어 통상과 같이 릴리이즈편(8)이 들리면 제 2b도와 같이 그 누르개(9)가 직접 접촉하고 있는 일측 록커의 눌림단부(4)를 화살표 방향으로 누르고 그 안쪽에 겹쳐있는 타측 눌림단부(4')도 함께 눌려지므로 양쪽록커의 걸림편(2)(2')끝은 다같이 릴(6)(6')의 요철부(7)(7')에서 빠져나와(록킹해제)릴(6)(6')은 어느 방향으로도 회전 가능하게된다.On the contrary, when the cassette is seated in the tech and the release piece 8 is lifted as usual, as shown in FIG. Since the pressed end 4 'is also pressed together, the ends of the locking pieces 2, 2' of both rockers come out of the uneven portions 7 and 7 'of the reels 6 and 6' (unlocking). The reels 6 and 6 'are rotatable in any direction.

다시 데크로부터 카세트가 인출되면 타측의 록커가 록킹해제됨에 따라 압축되었던 스프링(10)의 탄성이 그록커의 눌림편(3')을 반대로 밀어주는 힘으로 작용하므로 그 눌림단부(4')가 일측록커의 눌림단부(4)를 밀어주고 이에 누르개(9)도 반대로 밀리어 초기상태와 같이 모두 복귀된다.When the cassette is withdrawn from the deck again, the other end of the locker is unlocked, and thus the elasticity of the compressed spring 10 acts as a force for pushing against the pressing piece 3 'of the rocker. The pusher end 4 of the rocker is pushed in, and the pusher 9 is thus also returned to the initial state of the miller.

따라서 양측 록커의 걸림편(2)(2')은 똑같이 스프링(10)의 탄성을 받아 각각의 릴(6)(6')을 록킹시키는 것이다.Therefore, the locking pieces 2 and 2 'of both rockers receive the elasticity of the spring 10 to lock the respective reels 6 and 6'.

결과적으로 본 고안 장치는 한개의 스프링만으로도 록커의 기능을 충분히 발취케하므로 원가절감은 물론 그 조립시간도 단축되는 효과를 가져오는 것이다.As a result, the device of the present invention is enough to extract the function of the locker with only one spring, resulting in the effect of reducing the cost as well as the assembly time.
