본 고안은 캡스턴 서치방식을 채택하는 기계식 브레이크 방식의 VTR에 있어서, 수용측 릴 디스크의 하단에서 스프링의 탄성을 갖는 회전편과 연동하는 작동편을 이용하여 재생시나 녹화시에는 약 브레이크가 작동하고 고속감기(FF)나 되감기(REWIND)시에는 약 브레이크가 해저되게 하여 테이프의 주행이 원활하도록 한 VTR의 수용측 릴 디스크의 약 브레이크 장치에 관한 것이다.The present invention is a mechanical brake type VTR adopting the capstan search method, and the brake is operated at high speed during regeneration or recording by using an operation piece which interlocks with a spring-elastic rotating piece at the lower end of the reel disk. The present invention relates to a weak braking device for a receptacle disk on the receiving side of a VTR, in which the weak brake is lowered at the time of winding (FF) or rewinding (REWIND) to smooth the running of the tape.
종래에는 VTR의 테이프가 주행할 때 모우드가 재생이나 녹화시에는 약 브레이크가 작동하고 고속감기나 되감기에는 브레이크의 작동이 중단되도록 하기 위해 릴디스크의 브레이크를 솔레노이드를 이용한 전자식과 모터로 캠을 회전시켜 각종 링크와 레버로 동작시키는 기계식이 있으나 전자식은 간단히 작동되고 구조가 비교적 간단히 이루어져 있으나 그 가격이 비싸므로 기계식을 주로 이용하지만 브레이크 작동시 모터를 필히 구동시켜야만 하므로 부품이 복잡하여지고 확실한 브레이크의 작동을 위하여 안전장치를 같이 설치해야 하는 번거로움이 있음은 물론 정지 모우드시에 작동하는 강 브레이크와 재생모우드나 녹화모우드에서 작동하는 약 브레이크의 기능이 하나의 기계장치에서 이루어지므로 구조가 복잡하여 안정되고 확실한 작동이 이루어지지 않고 오동작의 우려가 있는 것이다.Conventionally, the brake of the reel disk is rotated by an electric motor using a solenoid and a cam to rotate the brake of the reel disc so that the brake operates when the mode is played or recorded when the tape of the VTR runs. There are mechanical mechanisms that operate with various links and levers, but the electronics are simple to operate and the structure is relatively simple, but the price is expensive, so the mechanical type is mainly used. In addition, it is not only hassle to install safety device, but also the function of the steel brake that operates in the stop mode and the weak brake that operates in the regeneration mode or the recording mode is done in one machine. This works Do not control that will cause malfunction.
이와같은 종래의 단점을 보완하기 위하여 수용측 릴 디스크이 하단에서 스프링의 탄성을 갖고 힌지를 중심으로 회전하는 회전편의 걸림편을 걸어주는 돌기가 일체로 된 작동편을 이용하여 핀치 로울러의 작동에 따라 약 브레이크의 작동을 넣었다 뺐다 할 수 있도록 한 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to compensate for the above disadvantages, the receiving side reel disk has a spring elasticity at the lower end and uses a working piece with a protrusion that hangs the engaging piece of the rotating piece that rotates around the hinge. It is to be able to put in and out of the operation of the brake, which will be described in detail by the accompanying drawings as follows.
캡스턴 서치방식을 채택하는 기계식 브레이크 방식의 VTR에 있어서, 수용측 릴 디스크(1)의 하단에 회전마찰력을 주기 위한 펠트부(FELT)(1-1)접착 형성하고 상기 펠트부(1-1)와 상면(2-1)이 회전시에 마찰을 일으키며 하단에 톱니형 치차(2-2)가 일체인 걸림부(2)를 수용측 릴 디스크(1)의 끼움부(1-2)에 기운채 스프링(3)의 탄성을 갖도록 고정부(4)를 압착시키며, 일측의 스프링걸이(5-1)에 코일스프링(5-5)이 탄지되고 걸림부(2)의 치차(2-2)에 걸리는 돌편(5-2)이 일체이며, 힌지(5-3)를 중심으로 회전하는 회전편(5)에 걸림편(5-4)을 일체로 형성하고, 회전편(5)의 걸림편(5-4)에 걸리는 돌기(6-1)가 일체이고, 축(6-2)을 중심으로 회전하는 작동편(6)에 밀편(6-3)을 일체로 형성하여, 캡스턴 샤프트(7)를 타고 이동하는 테이프(8)의 주행상태에 따라 축(9-1)을 중심으로 회전하는 핀치로울러(9)의 돌턱(9-2)과 맞닿도록 한 것이다.In the mechanical brake type VTR adopting the capstan search method, a felt part (FELT) 1-1 is formed to adhere to the lower end of the receiving side reel disk 1, and the felt part 1-1 is formed. The upper and lower surfaces 2-1 cause friction when they rotate, and the catching portion 2 having the toothed gear 2-2 integrated therein is attached to the fitting portion 1-2 of the receiving side reel disk 1. The fixing part 4 is compressed to have the elasticity of the spring 3, and the coil spring 5-5 is supported by the spring hook 5-1 on one side and the gear 2-2 of the locking part 2 is held. Protrusion 5-2 is integrally formed, the locking piece 5-4 is integrally formed on the rotating piece 5 rotating about the hinge 5-3, and the locking piece 5 of the rotating piece 5 is integrated. (5-4), the projection 6-1 is integrally formed, the push piece 6-3 is integrally formed on the operating piece 6 which rotates about the shaft 6-2, and the capstan shaft 7 Pin rotating about the shaft 9-1 according to the running state of the tape (8) moving in the And dolteok (9-2) of the roller (9) is to abut one.
이와같은 본 고안의 VTR에 테이프를 삽입한 다음 재생버턴을 눌러 재생모우드로 된 때에는 제1도에 도시된 바와같이 테이프(8)는 캡스턴 샤프트(7)를 타고 이동하며 로딩될 때 핀치로울러(9)는 축(9-1)을 중심으로 회전하며 돌턱(9-2)이 작동편(6)의 밀편(6-3)을 밀게되어 화살표방향으로 회전하면서 돌기(6-1)가 회전편(5)의 걸림편(5-4)을 밀어줘 회전편(5)도 힌지(5-3)을 중심으로 화살표 방향으로 회전하고 이에 따라 회전편(5)의 돌편(5-2)이 걸림부(2)의 치차(2-2)에 걸리게 되어 압착된 스프링(3)의 탄성과 걸림부(2)의 상면(2-1)과 펠트(1-1)와의 마찰력에 의해 수용측 릴 디스크(1)에 약 브레이크가 걸리는 것이다.When the tape is inserted into the VTR of the present invention and then the play button is pressed into the play mode, the tape 8 moves on the capstan shaft 7 as shown in FIG. ) Is rotated about the shaft (9-1) and the projection (9-2) pushes the push piece (6-3) of the working piece (6) while rotating in the direction of the arrow, the projection (6-1) the rotating piece ( 5) The locking piece 5-4 is pushed so that the rotating piece 5 also rotates in the direction of the arrow about the hinge 5-3, and thus the stone piece 5-2 of the rotating piece 5 is locked. Receiving-side reel discs (2) by the elasticity of the spring (3) pressed by the gear (2-2) of the (2) and the frictional force between the upper surface (2-1) and the felt (1-1) of the engaging portion (2) The brake is about 1).
그리고 되감기나 빨리감기모드가 주어지면 제2도에 도시된 바와같이 핀치로울러(9)가 축(9-1)을 중심으로 회전하며 캡스턴 샤프트(7)에서 멀어지게 되고 일측의 스프링 길이(5-1)에 탄지된 코일스프링(5-5)의 탄성으로 회전편(5)이 화살표 방향으로 회전하면서, 돌편(5-2)이 걸림부(2)의 치차(2-2)를 걸어줌으로써 약 브레이크가 작동한다.Given the rewind or fast rewind mode, the pinch roller 9 rotates about the shaft 9-1 as shown in FIG. 2 and moves away from the capstan shaft 7 and the spring length of one side (5-). The rotary piece 5 is rotated in the direction of the arrow by the elasticity of the coil spring 5-5 supported by 1), and the protrusion piece 5-2 engages the teeth 2-2 of the latching part 2 by about. The brakes work.
이때 회전편(5)의 걸림편(5-4)이 작동편(6)의 돌기(6-1)를 밀어주고 축(6-2)을 중심으로 회전하는 작동편(6)의 밀편(6-3)이 핀치로울러(9)의 돌턱(9-2)에 맞닿게 됨으로써 약 브레이크의 정도가 제한되는 것이다.At this time, the engaging piece 5-4 of the rotating piece 5 pushes the projection 6-1 of the operating piece 6 and rotates about the shaft 6-2. -3) comes into contact with the sill 9-2 of the pinch roller 9, thereby limiting the degree of weak brake.
이와같이 수용측 릴 디스크(1)의 하단에 펠트(1-1)와 마찰을 갖는 상면(2-1)이 일체인 걸림부(2)와 스프링(3)을 장치하고 회전편(5) 및 작동편(6)을 회전시켜서 재생모우드와 녹화모우드시에 약 브레이크의 작용이 원활히 이루어지며 그 구성이 간단하고 오동작의 염려가 없는 것이다.In this manner, the lower end of the receiving side reel disk 1 is provided with a locking part 2 and a spring 3 in which an upper surface 2-1 having friction with the felt 1-1 is integrated, and a rotating piece 5 and an operation. Rotating piece (6) is a smooth brake in the playback mode and the recording mode is made smoothly, the configuration is simple and there is no fear of malfunction.
