본 고안은 VTR의 릴 구동장치에서 테이프의 안정된 주행 및 양호한 감김상태를 유지해 주도록 VTR에 약브레이크장치를 설치한 것에 관한 것이다.The present invention relates to the installation of a weak brake device in the VTR to maintain a stable running of the tape and a good winding state in the reel drive of the VTR.
일반적으로 VTR에 설치한 약브레이크는 구조가 복잡하여 테이프의 안정된 주행과 양호한 감김상태를 유지해주기가 어려웠고, 또한 약브레이크를 제어해주는 솔레노이드를 설치하였으나 나 이역시 정확한 작동이 되지 못하였다. 이에 본 고안에서는 상기의 문제점을 해결하기 위하여 캠레버와 연결된 제 1 핀치레버를 작동봉의 일단에 열결시키고, 작동봉의 타단은 텐션아암과 연결시키며 작동봉의 양쪽에는 돌기를 각각 형성시키되 상기 돌기 옆쪽에는 제 1 브레이크레버와 제2, 3브레이크 레버를 설치하여 공급릴과 감이릴에 감겨 있는 테이프상태를 양호하게 할 수 있는 VTR의 약브레이크장치를 제공함에 목적이 있다.In general, the weak brake installed in the VTR has a complicated structure, making it difficult to maintain stable running of the tape and good winding state. Also, a solenoid for controlling the weak brake is installed, but it cannot be operated correctly at this age. In this invention, in order to solve the above problems, the first pinch lever connected to the cam lever is connected to one end of the operating rod, the other end of the operating rod is connected to the tension arm, and the protrusions are formed on both sides of the operating rod, respectively. It is an object of the present invention to provide a weak brake device of a VTR that can provide a good state of a tape wound around a supply reel and a reel by installing a first brake lever and second and third brake levers.
본 고안을 첨부된 도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.
본 고안은 작동봉(1)의 일단을 캠레버(2)의 제 1 핀치로울러레버(3)에 연결되게 하되 작동봉(1)의 타단은 텐션아암(4)에 연결되게 하고, 작동봉(1) 양쪽에는 돌기(5)(5')를 각각 형성시켜 돌기(5)(5')옆쪽에 설치한 제 1 레버브레이크(6)와 제2, 3레버브레이크 (7)(8)등을 밀어줄 수 있게 한 구조로 되어 있다. 그리고 텍크부(9)에 설치한 캠(10)에 의해 캠레버(2)와 제 1 핀치로울러레버(3)가 회동 되도록 하되 상기 제 1 핀치로울러레버(3)에는 제 1 고정핀 (11)을 설치하여 제 1 고정핀(11)을 중심으로 제 1 핀치로울러레버(3)가 회동될 수 있게 하고, 상기 제 1 핀치로울러레버(3)는 작동봉(1)과 연결되게 하되 제2, 3핀치로울러레버(12)(13)와도 연결되게한 것으로 되어 있다. 또한 핀치로울러(14)를 갖춘 제3핀치로울러레버(13)는 제 2 고정핀(15)을 중심으로 회동되도록 하였고, 덴션아암(4)은 제 1 스프링(16)과 연결하였으며 제 1 레버브레이크(6)는 제 3 고정핀(17)으로 덱크부(9)에 회동가능하게 설치한 것으로 되어 있고, 제 1 레버브레이크(6)옆쪽의 덱크부(9)에는 제1 스토파(18)를 설치하여 제 1 레버브레이크(6)가 공급릴 (19)의 테이프를 일정하게 밀어줄 수 있도 하였다.The present invention allows one end of the operating rod (1) to be connected to the first pinch roller lever (3) of the cam lever (2), while the other end of the operating rod (1) is connected to the tension arm (4), the operating rod ( 1) Protrusions 5, 5 'are formed on both sides, and the first lever brake 6 and the second and third lever brakes 7, 8, etc. installed on the sides of the protrusions 5, 5' are provided. It is structured to be able to push. In addition, the cam lever 2 and the first pinch roller lever 3 are rotated by the cam 10 installed in the tex section 9, but the first pin pin 11 is attached to the first pinch roller lever 3. By installing the first pinch roller lever (3) is rotated around the first fixing pin 11, the first pinch roller lever (3) is to be connected to the operating rod (1) The three-pinch roller levers 12 and 13 are also connected to each other. In addition, the third pinch roller lever 13 having the pinch roller 14 is rotated about the second fixing pin 15, and the tension arm 4 is connected to the first spring 16 and the first lever brake. 6, the third fixing pin 17 is rotatably attached to the deck portion 9, and the first stopper 18 is attached to the deck portion 9 on the side of the first lever brake 6. As shown in FIG. By installing, the first lever brake 6 could constantly push the tape of the supply reel 19.
한편, 제2, 3레버브레이크(7)(8)는 핀(20)으로 연결시키되 제 4 고정핀(21)으로 회동가능하게 덱크부(9)에 고정시킨 것으로 되어 있고, 제 1 레버브레이크(6)와 제 2 페버브레이크(7)에는 각각 제 2 스프링(22)을 설치하여 제1,2레버브레이크(6)의 회동이 원할하게 되도록 하였으며, 제2, 3레버브레이크(7)(8)의 중간 덱크부(9)에는 제 2 스토파(23)를 설치하였다.On the other hand, the second and third lever brakes (7) (8) are connected to the pin (20), but is fixed to the deck portion (9) to be rotatable by the fourth fixing pin (21), the first lever brake ( 6) and second lever brakes 7 are provided with second springs 22, respectively, so that the rotation of the first and second lever brakes 6 is smooth, and the second and third lever brakes 7 and 8 are provided. In the middle deck portion 9 of the second stopper 23 was installed.
제 2 도의 작동상태에서 캠(10)을 회전시키면 캠(10)과 연결된 캠레버(2)가 제 1 화살표방향(24)으로 움직이게 됨과 동시에 제 1 핀치로울러레버(3)가 약간 회동되면서 작동봉(1)을 제 2 화살표방향(25)으로 당기게 되는데 이때 제 1 핀치로울러레버(3)와 연결된 제 2 핀치로울러레버(12)와 제 3 핀치로울러레버(13)등을 회동시켜 핀치로울러(14)가 캡스턴(26)에 밀착되게 한다.When the cam 10 is rotated in the operating state of FIG. 2, the cam lever 2 connected to the cam 10 moves in the direction of the first arrow 24, and at the same time, the first pinch roller lever 3 rotates slightly to operate the rod. (1) is pulled in the direction of the second arrow 25. At this time, the second pinch roller lever 12 and the third pinch roller lever 13 connected to the first pinch roller lever 3 rotate and the like, and the pinch roller 14 ) Is in close contact with the capstan 26.
이와 동시에 텐션아암(4)도 회동되고 작동봉(1)의 돌기(5)는 제 1 레버브레이크(6)를 밀어 공급릴(19)에 접촉되어 있던 제 1 레버브레이크(6)가 떨어지게 되며 작동봉(1)의 돌기(5')는 제 2 레버브레이크(7)를 밀어주게 되고, 제 3 레버브레이크(8)는 제 2 스토파(23)에 의해 즉 핀(30)을 중심으로 약간 회동되므로 감이릴(27)에서 제 3 레버브레이크(8)가 떨어지게 된다.At the same time, the tension arm 4 is also rotated and the projection 5 of the operating rod 1 pushes the first lever brake 6 so that the first lever brake 6 which has been in contact with the supply reel 19 falls and operates. The projection 5 'of the rod 1 pushes the second lever brake 7, and the third lever brake 8 is rotated slightly by the second stop 23, i.e. about the pin 30. Therefore, the third lever brake 8 falls from the reel 27.
즉 상기와 같은 동작은 테이프가 로딩될때의 상태이다. 또한 제 1 레버브레이크(6)와 제2,3레버브레이크(7)(8)가 공급릴(19)과 감이릴(27)에 접촉된 상태는 테이프가 언로딩된 상태이다.That is, the above operation is a state when the tape is loaded. In addition, the state in which the first lever brake 6 and the second and third lever brakes 7 and 8 are in contact with the supply reel 19 and the reel 27 is a state in which the tape is unloaded.
물론 본 고안에서는 로딩된 상태로 플레이중일 때는 텐션아암(4)과 공급릴(19)에 설치된 밴드텐션(28)에 의해 별도의 약브레이크가 필요치 않으나, 언로딩상태에서 테이프를 빨리 보내기 또는 리와인드시킬 때는 밴드텐션(28)이 작용되지 않으므로 이때에만 본 고안의 약브레이크가 적용된다. 특히 본 고안에서 테이프를 빨리 보내기와 리와인드를 시키고난 후 제1, 2, 3레버브레이크(6)(7)(8)를 공급릴(19)과 감이릴(27)에 긴밀하게 접촉되게 하므로 테이프의 취급을 아주 용이하게 할 수 있어서 사용자의 편리함을 도모할 수 있다.Of course, the present invention does not require a separate weak brake by the tension arm (4) and the band tension (28) installed in the supply reel (19) when playing in the loaded state, but to quickly send or rewind the tape in the unloaded state. When the band tension 28 is not applied, only the weak brake of the present invention is applied at this time. In particular, in the present invention, the first, second and third lever brakes 6, 7 and 8 are brought into intimate contact with the supply reel 19 and the reel 27 after the tape is quickly sent and rewinded. The handling of the tape can be made very easy, and the user's convenience can be attained.
이상의 설명에서와 같이 제1, 2, 3레버브레이크(6)(7)(8)를 공급릴(19)과 감이릴(27)에 긴밀하게 접촉되게 하므로써 기록, 재생, 소리의 부조화가 일어나지 않아 VTR의 전반적인 기능을 향상시킬 수 있는 효과가 있다.As described above, the first, second, and third lever brakes 6, 7, and 8 are brought into intimate contact with the supply reel 19 and the reel 27 to prevent recording, reproduction, and sound inconsistency. As a result, the overall function of the VTR is improved.
