본 고안은 비디오 테이프 레코오더의 테이프릴 급속브레이크장치에 관한 것으로, 특히 간단한 구조로 급송이나 빨리되감기 모우드(FF/REW)에서 정지모우드로 전환시 원활하게 릴을 급속제동 시킬 수 있도록한 브레이크장치에 관한 것이다.The present invention relates to a tape reel rapid brake device of a video tape recorder, and particularly to a brake device that enables a quick reel to be braked smoothly when switching from feeding or fast rewinding mode (FF / REW) to a stop mode with a simple structure. It is about.
종래 프론트 로딩방식에서 급송 또는 빨리되감기 모우드로 부터 정지모우드로 전환시킬 수 있도록한 급속브레이크장치는 라쳇트기어등과 같은 여러부품으로 구성되고 이에 의하여 테이프릴의 급속제동이 이루어지므로 그 작동이 원활치 못하여 소음이 발생되는 등의 결점이 있었다.In the conventional front loading method, the quick brake device that can be switched from the fast forwarding or fast rewinding mode to the stop mode is composed of several parts such as ratchet gears. There were defects such as noise.
본 고안에서는 프론트 로딩방식에 있어서 카세트의 안착이나 이젝트를 위하여 별도의 모우터를 이용하지 않고 로딩모우터를 이용한 구성과 결합되는 간단한 구조로 테이프릴의 급속제동을 가능하게 함으로써 부품수를 줄이고 작동이 원활하며 소음이 발생되지 않는 테이프릴의 급속브레이크장치를 제공하는데 그 목적이 있는 것인바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present design, the front loading method reduces the number of parts and reduces the number of operations by enabling rapid braking of the tape reel with a simple structure that is combined with the configuration using the loading motor without using a separate motor for seating or ejecting the cassette. The purpose is to provide a smooth and noise-free rapid brake device of the tape reel bar, which will be described in more detail based on the accompanying drawings.
하우징 브라킷트(1)에자형 안내로(2)가 형성되고 이에 핀(3)으로 안내되는 카세트홀더(4)가 내측에 착설되며, 하우징브라킷트(1)의 외측에는 핀(3)이 삽입되어 안내되는 장공(5)을 갖는 안내판(6)이 로딩기어(7)와 함께 축설되어 스프링(8)으로 연결되고, 메인샷시(9)의 저면부에는 풀리(10)를 갖는 로딩모우터(11)가 착설되며, 소기어(12)를 갖는 풀리(13)가 축설되어 벨트(14)로 풀리(10)와 연결되고 소기어(12)와 탈락되거나 교합될 수 았는 제1연결기어(15)와 이에 교합된 제2연결기어(16)가 축설된 레바(17)를 축(18)으로 축설하여 후단부(19)가 내향토록 스프링(20)으로 탄지하며 내측에는 레바(17)의 후단부(19)가 내향되는 범위를 규제하는 스토파(21)를 입설하고, 다시 소기어(12)에 두 연결기어(22)(23)가 교합연결되어 캠(24)이 연결되어 있으며, 레바(17)의 축(18)은 상부로 연장하여 그 단부의 웜기어(25)를 로딩기어(7)에 연결하고, 공급릴(26)과 권취릴(27)에 인접하여 각각 브레이크(28)(29)를 핀(30)(31)으로 축설하고 이들의 내단부(32)(33)이 중첩되고 스프링(34)으로 탄지된 것에 있어서, 메인샷시(9)에 가이드(35)를 착설하여 사각공(36)을 갖는 플레이트(37)를 전개하고 그 선단부에 핀(38)을 입설하여 레바(17)의 후단부(19)에 접하도록하며 플레이트(37)의 후단부(39)는 솔레노이드(40)에 연결하고, 공급릴(26)의 브레이크(28)에 핀(41)을 입설하여 플레이트(37)으사각공(36)에 삽입하여서된 구조이다.On the housing bracket (1) A male guide (2) is formed and a cassette holder (4) guided to the pin (3) is installed on the inside, and the long hole (5) in which the pin (3) is inserted and guided to the outside of the housing bracket (1). Guide plate (6) having a built-in with the loading gear (7) is connected to the spring (8), the loading motor (11) having a pulley (10) is installed on the bottom of the main chassis (9), The first connecting gear 15 and the second mating gear 15 are constructed so that the pulley 13 having the gear 12 is built up and connected to the pulley 10 by the belt 14 and may be dropped or engaged with the small gear 12. The rear end portion 19 is supported by the spring 20 so that the rear end portion 19 is extended to the shaft 18, and the rear end portion 19 of the lever portion 17 is inward. The stopper 21 which regulates the range is installed, and two connecting gears 22 and 23 are bite-coupled to the small gear 12, and the cam 24 is connected, and the shaft 18 of the lever 17 is connected. ) Extends upwards to the worm at its ends The gear 25 is connected to the loading gear 7, and adjacent to the supply reel 26 and the take-up reel 27, the brakes 28 and 29 are laid out with pins 30 and 31, respectively. In the end portions 32 and 33 overlapped and supported by the springs 34, a guide 35 is installed in the main chassis 9 to develop a plate 37 having a square hole 36, and at the tip end thereof. The pin 38 is inserted in contact with the rear end 19 of the lever 17, and the rear end 39 of the plate 37 is connected to the solenoid 40, and the brake 28 of the supply reel 26 is inserted into the pin 38. The pin 41 is inserted into the plate 37 and inserted into the square hole 36.
이와같은 본고안은 하우징브라킷트(1)내의 카세트홀더(4)에 카세트를 넣고 로우딩작동시킬때 제4도와 같은 상태에서 로우딩 모우터(11)가 구동하여 풀리(13)가 회전하고 소기어(12)와 교합되어 있는 제1연결기어(15)와 제2연결기어(16)를 회전시킨다. 따라서 그 축(18)과 웜기어(25)가 회전하여 기어(7)를 회전시킴으로써 카세트를 안착시킨다.In this paper, when the cassette is inserted into the cassette holder 4 in the housing bracket 1 and the loading operation is performed, the loading motor 11 is driven in the state as shown in FIG. The first connecting gear 15 and the second connecting gear 16 engaged with the gear 12 are rotated. Therefore, the shaft 18 and the worm gear 25 are rotated to rotate the gear 7 to seat the cassette.
카세트가 안착되는 과정에서는 플레이트(37)에 형성된 사각공(36)과 공급축 브레이크(28)의 핀(41)은 서로 닿지않고 사각공(36) 내의 위치(제4도)에 있으므로 공급릴(26)과 권취릴(27)은 각각의 브레이크(28)(29)로 제동이 걸려 있는 상태이다. 카세트가 안착된후 재생이나 급송/빨리되감기, 레코드모우드에서는 솔레노이드(40)에 의하여 플레이트(37)가 ˝D˝방향으로 이동하여 사각공(36)의 일측단부에 브레이크(28)의 핀(41)이 닿아 밀리게 되고 공급측 브레이크(28)가 시계방향으로 회전하여 이 공급측 브레이크(28)와 권취측 브레이크(29)가 함께 해제된다. 만약 급송/빨리되감기 모우드로부터 정지모우드로 전환하는 경우 솔레노이드(40)가 플레이트(37)를 ˝C˝방향으로 이동시켜 공급측브레이크(28)의 핀(41)을 플레이트(37)의 사각공(36)의 중앙부측으로 이동될 수 있도록 해제하면 각 브레이크(28)(29)가 작동하여 각 릴(26)(27)을 급송제동시키는 것이다.In the process of seating the cassette, the square hole 36 formed in the plate 37 and the pin 41 of the supply shaft brake 28 are not in contact with each other, but are in a position (FIG. 4) in the square hole 36. 26 and the reel 27 are braked by the respective brakes 28 and 29. After the cassette is seated, in the playback, feeding / fast rewinding, and record mode, the solenoid 40 moves the plate 37 in the ˝D˝ direction so that the pin 41 of the brake 28 is provided at one end of the square hole 36. ) Is pushed back and the supply side brake 28 rotates clockwise so that the supply side brake 28 and the winding side brake 29 are released together. If the feed / fast rewind mode is changed from the stop mode to the stop mode, the solenoid 40 moves the plate 37 in the direction of ˝C 시켜 to move the pin 41 of the supply side brake 28 to the square hole 36 of the plate 37. When released to be moved to the center portion of the) is to brake each brake (28, 29) to operate each reel (26) (27).
이와같은 본고안은 간단한 구조로 급송이나 빨리되감기 모우드에서 정지모우드로 전환시 원활하게 릴을 급속 제동시킬 수 있는 것이다.This is a simple structure that can smoothly brake the reel when feeding or switching from fast rewind mode to stationary mode.
