본 고안은 비디오 테이프 레코오더(VTR)에 있어서, 테이프의 초기주행상태를 안정되게하여 줄 수 있도록한 리일디스크 이중 브레이크장치에 대한 것이다.The present invention relates to a real disk dual brake device that can stabilize the initial driving state of a tape in a video tape recorder (VTR).

종래에는 로오딩동작시 캡스턴모우터의 구동에 의해 테이프가 카세트에서 최초로 나올때 약브레이크 하나로 리일디스크의 회전을 제어토록 하였기 때문에 완전한 브레이크 작용이 되지 못하는 결점이 있었고, 이에 따라 테이프가 느슨하게 풀려지는 현상이 발생되고 이로인해 테이프가 훼손되거나 또는 로오딩이 불안정하게 되는 등의 폐단이 있었다.Conventionally, when the tape comes out of the cassette for the first time by the driving of the capstan motor during the loading operation, the brake is controlled by one brake, so that the complete brake action is not achieved. Accordingly, the tape is loosened. Generated, resulting in tape breakage or unstable loading.

본 고안은 이러한 점들을 해결하기 위해 약 브레이크와 밴드 브레이크를 리일디스크 양측에 설치하여 슬라이드판에 의해 순차적으로 작동되게 이중 브레이크 장치를 한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention will be described in detail with reference to the accompanying drawings.

리일디스크(2)의 일측방에는 약브레이크(3)를 비틀림스프링(4)에 의해 탄력설치되게 핀(5)으로 데크(1)에 회전자재토록 착설하고, 그 일측부에는 안내편(6)을 그 일부가 노출되게 끼워 고정시키며, 타측방에는 밴드브레이크(7)를 일끌은 고정편(8)으로 데크(1)에 고정착설하고, 타측끝은 인장스프링(9)으로 당겨지게 데크(1)에 핀(10)으로 착설한 레버(11)에 결착하며, 이 레버(11)의 일측에는 안내핀(6')을 그 일부가 하부로 노출되게 끼워 고정하고 안내핀(6)(6')들은 각각 데크(1)에 뚤어진 장공(12)(12')을 통해 테크(1)저면에 착설하는 슬라이드판(13)에 뚤어진 ""형상의 안내공(14)과 ""형상의 안내공(14')에 각기 결합되게하며, 슬라이드판(13)은 마스터캠(15)의 상면에 형성된 캠홈(16)을 따라 이동되는 레버핀(17)을 갖는 작동레버(18)에 의해 좌우 이동자재토록하고, 마스터캠(15)은 워엄(19)과 맞물리게하여 모우터(20)에 의해 회전되도록 하여서된 것이다.On one side of the reel disk 2, the weak brake 3 is installed on the deck 1 with the pin 5 so as to be elastically installed by the torsion spring 4, and on one side thereof, the guide piece 6 Part is exposed and fixed, the other side is fixed to the deck (1) by the fixing piece (8) attracting the band brake (7), the other end is pulled by the tension spring (9) deck (1) And a guide pin 6 'attached to one side of the lever 11 so that a part thereof is exposed downward, and the guide pin 6 and 6' are fixed to one side of the lever 11. Are each bent on the slide plate 13 which is installed on the bottom of the tech 1 through the holes 12 and 12 'which are bent on the deck 1, respectively. "Shape guide 14" And an actuating lever 18 having a lever pin 17 moved along the cam groove 16 formed on the upper surface of the master cam 15, the slide plate 13 being respectively coupled to the "shaped guide hole 14 '. By the left and right moving material, the master cam 15 is to be rotated by the motor 20 to be engaged with the worm (19).

이와같이 된 본 고안은 제2도(가)에서 보는 바와 같이 슬라이드판(13)이 좌측으로 완전히 이동하게되면, 약브레이크(3)와 밴드브레이크(7)의 레버(11)에 고정부착된 안내핀(6)(6')이 각각 슬라이드판(13)에 뚫어진 안내공(14)(14')의 우측부분, 즉 폭이 좁은 부분에 위치하게되므로 약브레이크(3)는 시계방향으로 회동되므로 비틀림스프링(4)을 벌려주면서 리일디스크(2)에서 떨어지게되고, 반대로 레버(11)는 반시계방향으로 회동되도록 인장스프링(1)은 늘어나게되고 밴드 브레이크(7)를 당겨주지 않게되어 이 밴드브레이크(7)로 리일디스크(2)에서 떨어지게되며, 이때 작동레버(18)의 레버핀(17)은 캠홈(16)의 외측끝부분에 위치하게 된다.The present invention has a guide pin fixedly attached to the lever 11 of the weak brake 3 and the band brake 7 when the slide plate 13 is completely moved to the left side as shown in FIG. (6) (6 ') is located at the right side of the guide hole (14, 14'), that is, the narrow part, each of which is drilled in the slide plate (13), so that the weak brake (3) rotates in the clockwise direction and is twisted. The spring (4) is pulled apart from the reel disk (2), on the contrary, the lever (11) is rotated counterclockwise so that the tension spring (1) is extended and the band brake (7) is not pulled out so that this band brake ( 7) is separated from the real disk 2, wherein the lever pin 17 of the operating lever 18 is located at the outer end of the cam groove (16).

이러한 상태에서 테이프의 로오딩이 시작되면 모우터(20)의 구동으로 워엄(19)에 의해 마스터캠(15)이 시계방향으로 회전되어 레버핀(17)이 제2도(b)에서 보는 바와 같이 캠홈(16)의 "A"부분에 도달하게되면 레버핀(17)이 이동된 만큼 작동레버(18)에 의해 슬라이드판(13)이 우측으로 이동되면, 이에 따라 안내공(14)(14')들도 이도오디는데, 이때 안내공(14)의 폭이 좁은 부분에 있던 안내핀(6)은 폭이 넓은 부분에 위치하게 되며, 이렇게 되면 벌어져 있던 비틀림스프링(4)의 복원력에 의해 약브레이크(3)가 반시계 방향으로 회동되어 리일디스크(2)의 측면에 접촉되어 1차로 구동을 제어하게 된다.In this state, when the loading of the tape starts, the master cam 15 is rotated clockwise by the worm 19 by the driving of the motor 20, and the lever pin 17 is as shown in FIG. When the “A” portion of the cam groove 16 is reached, the slide plate 13 is moved to the right by the operating lever 18 as much as the lever pin 17 is moved. Accordingly, the guide holes 14 and 14 are thus moved. ') Also the ear canal, wherein the guide pin (6) in the narrow portion of the guide hole (14) is located in the wide portion, this is about by the restoring force of the torsion spring (4) The brake 3 is rotated counterclockwise to come into contact with the side of the real disk 2 to primarily control driving.

그러나 약브레이크(3)가 동작을 시작하여도 밴드브레이크(7)는 레버(11)의 안내핀(6')이 아직도 안내공(14')의 폭이 좁은 부분에서 빠져나오지 못한 상태이므로 리일디스크(2)에 접촉되지 못하게되어 제동 작동을 하지 않게되며, 이러한 상태에서 약브레이크(3)의 작동이 일정시간 계속된 후에는 제2도 (c)에서 보는 바와같이 레버핀(17)이 캠홈(16)의 내측 끝부분에 위치하게되면, 이때에는 슬라이드판(13)이 우측으로 완전히 이동되며, 이에 따라 약브레이크(3)의 안내핀(6)은 계속 안내공(14)의 폭이 넓은 부분에 있게되어 약 브레이크 작동은 계속되며, 레버(11)의 안내핀(6')도 안내공(14')의 폭이 넓은 부분에 위치하게되므로 늘어나있던 인장스프링(9)의 수축력에 의해 레버(11)가 시계방향으로 회동되면서 밴드 브레이크(7)를 당겨주기 때문에 이 밴드브레이크(7)로 리일디스크(2)에 접촉되어 2차로 구동을 제어하게 되는 것이다.However, even when the weak brake 3 starts to operate, the band brake 7 is a rear disc because the guide pin 6 'of the lever 11 still does not escape from the narrow portion of the guide hole 14'. (2) can not be contacted so that the braking operation is not performed, and in this state, after the operation of the weak brake 3 continues for a predetermined time, as shown in FIG. When positioned at the inner end of the 16, the slide plate 13 is completely moved to the right at this time, so that the guide pin 6 of the weak brake 3 continues to the wide portion of the guide hole 14 Since the brake operation is continued, the guide pin 6 'of the lever 11 is also positioned in the wide part of the guide hole 14', so that the lever ( 11) rotates clockwise and pulls the band brake (7), so with this band brake (7) It is in contact with the real disk 2 to control the drive in the secondary.

이와같이 작동되는 본 고안은 해제시에는 모우터(20)을 역구동시켜주면 모든 동작이 반대로 진행되어 제동 작동이 해제되는 것으로, 최초로 테이프가 로오딩될때 또는 피워드모우드나 리와인드 모우드에서는 약 브레이크만 작동되게 슬라이드판(13)을 동작시키고, 이에 뚫은 안내공(14)(14')의 위히 편차를 주므로 양브레이크가 순차적으로 작동되게하여 초기의 테이프 주행상태가 안정되도록하며, 이에 따라 테이프의 늘어짐 현상이 제거되어 항상 적절한 텐션을 유지토록하여주고, 따라서 테이프의 늘어짐에 의한 훼손등도 방지되는등 매우 유용한 고안이다.The present invention, which is operated as described above, releases the motor 20 in reverse when all the movements are reversed so that the braking operation is released. When the tape is first loaded or only in the forward mode or the rewind mode, only the brake is activated. Since the slide plate 13 is operated so that the guide holes 14 and 14 ′ are deviated from each other, the two brakes are sequentially operated to stabilize the initial tape running state, thereby sagging the tape. This is a very useful design such that it is removed to maintain proper tension at all times, thus preventing damage caused by sagging tape.
