본 고안은 테이프를 장력을 가하기 위한 텐션폴과 캡스턴축에 압압되는 핀치로울러가 설치되는 VTR의 리브 아암과 핀치아암 구동장치에 관한 것이다.The present invention relates to a rib arm and a pinch arm driving device of a VTR in which a pinch roller pressed on a tension pole and a capstan shaft for tensioning a tape is installed.
일반적으로 VTR의 테이프는 회전하는 캡스턴축에 핀치로울러를 압압시켜 마찰 회전되는 캡스턴축과 핀치로울러 사이로 테이프를 주행시킴과 동시에 텐션 폴로 테이프에 장력을 가하여 일정한 속도로 안정된 주행이 이루어지도록 하는 것으로 종래의 VTR덱크에서 핀치 로울러를 설치한 핀치아암의 구동은 핀치아암과 슬라이드판사이에 여러개의 조인트판을 연결하여 슬라이드판의 동작이 여러개의 조인트판을 통해 핀치아암을 구동시킬수 있도록 하는 장치가 사용되고 있었으나 이는 다수의 부품을 사용하여 핀치아암을 구동시켜야 하는 것이므로 부품의 조립 공수가 증가될 뿐만 아니라 생산원가가 상승되는 점이 있었다.In general, the tape of the VTR presses the pinch roller on the rotating capstan shaft to drive the tape between the frictionally rotating capstan shaft and the pinch roller, while simultaneously applying tension to the tension polo tape to allow stable driving at a constant speed. In the case of driving the pinch arm with the pinch roller installed in the VTR deck, several joint plates were connected between the pinch arm and the slide plate so that the operation of the slide plate could drive the pinch arm through the multiple joint plates. Since the pinch arm needs to be driven by using the component of, the assembly cost of the component is increased and the production cost is increased.
본 고안은 이와 같은 결점을 감안하여 슬라이드판에 캠레버를 연결하고 캡레버의 회전시 리브 아암과 판치아암에 의해 직접 구동되도록 함으로서 조립 공수를 줄일수 있음은 물론 생산원가를 절감할 수 있도록한 VTR의 리브아암과 핀치아암 구동장치를 제공하기 위한 것으로 이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.In consideration of this drawback, the present invention connects the cam lever to the slide plate and is driven directly by the rib arm and the plate tooth when the cap lever rotates, thereby reducing assembly costs and reducing production costs. To provide a rib arm and pinch arm driving device of the VTR described in detail by the accompanying drawings as follows.
로딩모우터(2)의 회전동력을 밸트(3)을 통해 전달받는 위엄기어(4)에 캠홈(6)이 형성된 마스터캠(5)을 치합하고 힌지핀(7a)에 축착된 회동판(7)에는 캠홈(6)에 삽입되는 가이드핀(8)으로 슬라이드판(9)을 연결하여 구성된 일반 적인 동력전달 수단(1)의 슬라이드판(9)과 변위수단(10)의 캠레버(11)를 연결핀(9a)으로 회전가능하게 고정하되 고정 축(13)에 축착시킨 캠레버(1)의 일단(11b)에는 돌출핀(12)을 형성시켜 핀치아암(31)이 지지되도록 하고 타단(11a)에는 리브아암(21)의 걸림핀(23)이 지지되도록 구성하면 탄지부(20)의 걸림판(23)이 고정된 리브아암(21)에는 텐션폴(24)을 구성시켜 비틀림스프링(25)과 함께 고정핀(22)으로 축착하고 압압부(30)의 핀치로울러(34)가 설치된 핀치아암(31)에는 걸림턱(33)을 형성시켜 비틀림스프링(35)과 함께 고정축(32)으로 축착하여서된 것이다.Rotating plate 7 fitted with a master cam 5 having a cam groove 6 formed on the dignity gear 4 receiving the rotational power of the loading motor 2 through the belt 3 and being condensed on the hinge pin 7a. The cam lever 11 of the slide plate 9 and the displacement means 10 of the general power transmission means 1 constituted by connecting the slide plate 9 with guide pins 8 inserted into the cam groove 6. Is fixed to the connecting pin (9a) rotatably, but one end (11b) of the cam lever (1) fixed to the fixed shaft 13 to form a protruding pin (12) so that the pinch arm (31) is supported and the other end ( 11a) is configured to support the locking pins 23 of the rib arm 21, the tension pole 24 is formed on the rib arm 21 to which the locking plate 23 of the tungsten part 20 is fixed to torsion spring ( 25 together with the fixing pin 22 and the pinch arm 31 in which the pinch roller 34 of the pressing unit 30 is installed to form a locking jaw 33 to fix the shaft 32 together with the torsion spring 35. Condensed with) The.
이와 같이 구성된 본 고안은 동력전달수단(1)의 작용에 의해 좌, 우로 이동되는 슬라이드판(9)이 변위수단(10)의 캠레버(11)를 회전시킴과 동시에 탄지부(20)와 압압부(30)가 구동되어 리브아암(21)의 텐션폴(24)은 테이프에 장력을 가하고 핀치아암(31)의 핀치로울러(34)는 캡스턴축(36)을 압압하게 되는 것으로 VTR의 테이프의 재생 또는 녹화시 버튼을 누르면 캡스턴축(36)이 회전됨과 동시에 로딩모우터(2)에 전원이 인가되어 벨트(3)로 연결된 위엄기어(4)와 마스터캠(5)이 회전되면서 마스터캠(5)와 캠홈(6)위치가 제2도의 (a)상태에서 제2도의 (b) 상태로 변위되어 캠홈(6)에 삽입된 가이드핀(8)이 힌지핀(7a)에 축착된 회동판(7)을 회동시킴과 동시에 슬라이드판(9)을 당기게 되므로 연결핀(9a)에 의해 슬라이드판(9)과 연된됨 캠레버(11)가 고정 축(13)을 구동시키는 것이다.According to the present invention configured as described above, the slide plate 9 which is moved to the left and right by the action of the power transmission means 1 rotates the cam lever 11 of the displacement means 10 and at the same time the presser part 20 and the pressure. The pressure unit 30 is driven so that the tension pole 24 of the rib arm 21 applies tension to the tape, and the pinch roller 34 of the pinch arm 31 presses the capstan shaft 36. When the button is pressed during playback or recording, the capstan shaft 36 is rotated and power is applied to the loading motor 2 so that the dignity gear 4 and the master cam 5 connected by the belt 3 are rotated and the master cam ( 5) and the cam groove 6 are moved from the position of (a) in FIG. 2 to the position of (b) in FIG. 2 and the guide pin 8 inserted into the cam groove 6 is pivoted on the hinge pin 7a. (7) is rotated and the slide plate 9 is pulled at the same time, so the connecting pin 9a is connected to the slide plate 9 so that the cam lever 11 drives the fixed shaft 13. .
즉 캠러버(11)가 고정축(13)을 중심으로 회전하면 캠레버(11)의 일단(11b)에 형성된 돌출핀(12)은 핀치아암(31)을 절곡부(31a)를 밀계되어 압압부(30)이 핀치아암(31)은 고정축(32)을 중심으로 회전하면서 핀치로울러(34)를 캡스턴축(36)에 압압시킴과 동시에 걸림턱(33)이 비틀림 스프링(35)을 압축시키는 것이며 캠레버(11)의 타단(11a)은 고정핀(22)에 축착된 리브아암(21)의 길림핀(23)을 캠레버(11)의 회전 방향으로 밀게 되므로 텐션폴(34)이 핀치로울러(24)와 캡스턴축(36)사이에 압압된 테이프에 장력을 가하게 되어 테이프가 일정한 속도록 안정된 주행을 하게되는 것이다.That is, when the cam rubber 11 rotates about the fixed shaft 13, the protruding pins 12 formed on the one end 11 b of the cam lever 11 press the pinch arm 31 against the bent portion 31 a to be pressed. While the pressing unit 30 rotates the pinch arm 31 about the fixed shaft 32, the pinch roller 34 presses the capstan shaft 36 and the locking jaw 33 compresses the torsion spring 35. Since the other end 11a of the cam lever 11 pushes the girth pin 23 of the rib arm 21 which is fixed to the fixing pin 22 in the rotation direction of the cam lever 11, the tension pole 34 is Tension is applied to the tape pressed between the pinch roller 24 and the capstan shaft 36 so that the tape can run stably at a constant speed.
한편 VTR의 이적트(EJECT)버튼을 누르면 로딩모우터(2)가 역회전하면서 동력전달수단(1)이 상기와 역구동되어 가이드핀(8)이 슬라이드판(9)을 밀어줌과 동시에 병위수단(10)의 캠레버(11)가 최초의 위치로 복귀되는 것이며 탄지부(20)와 압압부(30)의 리브아암(21)과 핀치아암(31)은 각각의 비틀림스프링(25)(35)에 의해 탄성복귀된후 핀치아암(31)의 절곡부(31a)와 리브아암(21)의 걸림핀(23)이 캠레버(11)의 돌출핀(12)과 캠레버(11)의 타단(11a)에 걸려 복귀 완료되는 것이다.On the other hand, pressing the EJECT button of the VTR causes the loading motor 2 to rotate in reverse and the power transmission means 1 is driven back to the above, so that the guide pin 8 pushes the slide plate 9 and the bottle The cam lever 11 of the means 10 is returned to its original position, and the rib arm 21 and the pinch arm 31 of the stop section 20 and the pressing section 30 are each torsion spring 25 ( After the elastic return by 35, the bent portion 31a of the pinch arm 31 and the engaging pin 23 of the rib arm 21 are connected to the protruding pin 12 of the cam lever 11 and the cam lever 11. The return is completed by the other end (11a).
상기에서와 같이 본 고안은 슬라이드판에 위해 회전되는 캠레버로 텐션폴이 고정된 리브 아암과 핀치로울러가 설치된 핀치아암을 직접 구동시킴으로서 간단한 구성으로 리브아암과 핀치아암을 구동시킬수 있는 것이며 구성이 간단해짐으로서 조립공정의 간소화는 물론 구동장치의 생산원가를 절감할수 있는 효과가 있는 것이다.As described above, the present invention is capable of driving the rib arm and the pinch arm with a simple configuration by directly driving a rib arm having a tension pole and a pinch roller installed with a cam lever rotated on the slide plate. By simplifying the assembly process as well as the production cost of the drive device is to be reduced.
