본 고안은 복잡하게 구성되어 있는 핀치로울러 레버와 텐숀 유지 장치를 일체형으로 구성하여 로오딩 모터에서 동력을 전달받아 마스터캠이 회전하면 캠곡선에 의해 슬라이드 레버가 이동되면서 작동 레버를 동작시켜 주고 핀치로울러 레버와 아암텐숀 레버에 연결된 스프링에 의해 핀치로울러를 캠스탄축에 압착시켜 주도록 VTR 데크의 핀치로울러 압착장치의 개량에 관한 것이다.The present invention consists of a pinch roller lever and a tension holding device which are complicatedly constructed as a unit, and when the master cam is rotated by receiving power from the loading motor, the slide lever is moved by the cam curve to operate the operation lever and the pinch roller. The present invention relates to an improvement of the pinch roller pressing device of the VTR deck so that the pinch roller is pressed onto the camstan shaft by a spring connected to the lever and the arm tension lever.
종래에는 핀치로울러 압착 장치에서 핀치로울러 압착과 테이프 텐숀을 유지하기 위하여 핀치로울러 압착 장치에서 링크 3개를 사용하여 핀치로울러를 압착하였고 테이프 텐숀 유지를 위하여 아암 텐숀을 별도의 위치에 고정하여 핀치로울러 압착 동작 슬라이드 레버를 이용하여 테이프 텐숀을 유지하도록 복잡하게 구성되었다.Conventionally, in order to maintain the pinch roller crimp and tape tension in the pinch roller crimping device, the pinch roller is crimped using 3 links in the pinch roller crimping device. It was complicatedly constructed to maintain tape tension using an operating slide lever.
본 고안은 이와 같이 문제점을 개선하기 위하여 안출한 것으로 첨부 도면에 따라 상세히 설명하면 다음과 같다.The present invention is devised to improve the problem as described above in detail according to the accompanying drawings.
즉, 제1도 내지 제3도에서와 같이 로오딩 플레이트(1) 하면에 축설된 마스터캠(2)의 캠곡선(3)에 슬라이드 레버(4)의 일측 가이드편(5)을 삽입하고 로오딩 플레이트(1)상에 축지된 고정축(6)에 슬라이드 레버(4)의 장공(7)을 삽입하여 마스터캠(2)이 회전함에 따라 슬라이드 레버(4)를 좌우로 작동하도록 한 것에 있어 슬라이드 레버(4)의 타측 단부에 고정된 힌지핀(9)을 제3도에 도시한 바와 같이 로오딩 플레이트(1)상에 축지된 작동 레버(9)의 슬라이드홈(10)에 유삽하되 스프링 걸이공(11),(12)이 구비된 작동 레버(9)의 일측으로 상향 절곡한 스톱퍼(13)와 아암텐숀 레버(14)의 걸림돌기(15)가 접촉토록 부싱(16)을 이용하여 아암텐숀 레버(14)와 그 하방에 핀치로울러 레버(17) 및 아암텐숀 레버(14) 사이에 각각 스프링(18)(19)을 탄설하여서 된 것이다.That is, as shown in FIGS. 1 to 3, one guide piece 5 of the slide lever 4 is inserted into the cam curve 3 of the master cam 2 arranged on the lower surface of the loading plate 1, In inserting the long hole (7) of the slide lever (4) to the fixed shaft (6) supported on the ding plate (1) to operate the slide lever (4) from side to side as the master cam (2) rotates A hinge pin 9 fixed to the other end of the slide lever 4 is inserted into the slide groove 10 of the actuating lever 9 squeezed onto the loading plate 1 as shown in FIG. By using the bushing 16 so that the stopper 13 bent upward to one side of the actuating lever 9 provided with the hook holes 11 and 12 and the catching protrusion 15 of the arm tension lever 14 are in contact with each other. The springs 18 and 19 are piled up between the arm tension lever 14 and the pinch roller lever 17 and the arm tension lever 14 below.
미설명 부호 (20)은 핀치로울러, (21)은 텐숀폴, (22)는 캠스탄축, (23)은 테이프 가이드폴, (24)는 오디오 콘트롤 헤드, (25)는 테이프이다.Reference numeral 20 denotes a pinch roller, 21 a tension pole, 22 a camstane shaft, 23 a tape guide pole, 24 an audio control head, and 25 a tape.
이와 같이 구성된 본 고안은 제2도에서와 같이 모우터에서 동력을 전달받아 마스터 캠(2)이 회전하면 캠곡선(3)을 따라 슬라이드 레버(4)의 일측 가이드핀(5)이 상기 캠곡선(3)의 바깥쪽으로 밀어 나감에 따라 슬라이드 장공(7)이 로오딩 플레이트(1) 상에 축지된 고정축(6)에 안내되어 화살표 방향으로 이동함과 동시에 슬라이드 레버(4)의 힌지된(8)이 작동레버(9)의 슬라이드홈(10)에 유삽되어 있어 작동레버(9)는 축을 중심으로 반시계 방향으로 회동한다.According to the present invention configured as described above, when the master cam 2 is rotated by receiving power from the motor as shown in FIG. 2, one side guide pin 5 of the slide lever 4 moves along the cam curve 3 to the cam curve. As it slides out of (3), the slide hole (7) is guided to the fixed shaft (6) axially held on the loading plate (1), moving in the direction of the arrow, and hinged of the slide lever (4). 8) is inserted into the slide groove 10 of the operating lever 9 so that the operating lever 9 rotates counterclockwise about its axis.
이때 작동레버(9)의 스톱퍼(13)가 아암텐숀 레버(14)의 걸림돌기(15)를 밀게되어 아암텐숀 레버(14)의 텐숀폴(21)에 걸려 있는 테이프(25)에 텐숀을 주게 되며 동시에 작동레버(9)의 스프링 걸이공(11)과 핀치로울러 레버(17) 사이에 탄설된 스프링(19)에 의해 핀치로울러 레버(17)는 아암텐숀 레버(14)와 반대로 회동하여 핀치로울러 레버(17)의 핀치로울러(20)가 캠스턴축(22)에 밀착되어 테이프(25)를 압착하게 되는 것이다.At this time, the stopper 13 of the actuating lever 9 pushes the catching protrusion 15 of the arm tension lever 14 to give tension to the tape 25 hanging on the tension pole 21 of the arm tension lever 14. At the same time, the pinch roller lever 17 is rotated in opposition to the arm tension lever 14 by the spring 19 that is installed between the spring hook hole 11 of the actuating lever 9 and the pinch roller lever 17. The pinch roller 20 of the lever 17 is in close contact with the camston shaft 22 to compress the tape 25.
또한 원복될 때에는 마스터캠(2)의 캠곡선(3)에 의해 슬라이드 레버(4)가 화살표 반대 방향으로 이동하고 이와 함께 작동레버(9)는 축을 중심으로 시계 방향으로 회동함과 동시에 핀치로울러 레버(17)의 핀치로울러(20)도 캠스탄축(22)과 떨어지게 되고 동축상에 축설된 아암텐숀 레버(14)의 걸림돌기(15)와 작동레버(9)의 스톱퍼(13)가 이격되어 작동레버(9)와 아암텐숀 레버(14) 사이에 탄설된 스프링(18)이 축소되면서 아암텐숀 레버(14)는 원래의 위치로 원복되는 간단한 구성으로 부품수의 감소와 동작이 원활한 장점이 있는 것이다.In addition, when the roll is restored, the slide lever 4 is moved in the opposite direction to the arrow by the cam curve 3 of the master cam 2, and the operating lever 9 is rotated clockwise about the axis and at the same time the pinch roller lever. The pinch roller 20 of (17) is also separated from the camstan shaft 22, and the locking projection 15 of the arm tension lever 14 coaxially arranged and the stopper 13 of the operating lever 9 are spaced apart. As the spring 18 collapsed between the actuating lever 9 and the arm tension lever 14 is reduced, the arm tension lever 14 has a merit of reducing the number of parts and smooth operation by a simple configuration to be restored to its original position. will be.
