본 고안은 프론트로오딩 방식의 브이티알(VTR)에 있어서, 하나의 캠기어로 카세트의 로오딩 안착은 물론 핀치 아암도 구동시켜 줄 수 있도록한 브이티알의 카세트 하우징 및 핀치 아암 구동 장치에 대한 것이다.The present invention relates to a cassette housing and a pinch arm driving device of a VTI in a frontloading type VTR, which can drive a pinch arm as well as loading a cassette into a cam gear.
종래에는 2개의 캠기어를 설치하여 하나의 카세트 하우징을, 다른 하나는 핀치아암을 구동시켜 주도록 하였기 때문에 하우징 구동시에는 하우징이 구동되지 않게 하여 주어야 되므로 다른 한쪽이 구동될때 다른 쪽에서는 공회전 시키는 장치가 필요하였는데, 이 경우 공회전을 위한 구조가 복잡하고 부품 및 조립공수가 증가되어 원가의 상승은 물론 좁은 공간에 않은 부품의 설치에 따라 세트에 무리가 가고 조립공차 및 형합 상태등에 따라 그 동작이 원활하지 못하여 불량의 원인이 되는 등 많은 문제점들이 있었다.Conventionally, since two cam gears are installed to drive one cassette housing and the other to drive the pinch arm, the housing must not be driven when the housing is driven. In this case, the structure for idling is complicated, and the number of parts and assembly are increased, which increases the cost and makes the set difficult due to the installation of parts not in a narrow space. There were many problems, such as causing the defect.
본 고안은 이러한 점들을 감안하여 고안한 것으로 양측면 적정부위에 래크를 형성한 슬라이드판을 캠기어의 캠홈곡선에 의해 직선운동하게 데크에 설치하여 이 슬라이드판의 운동 간격에 따라 상기 래크들이 하우징을 구동시켜 주는 구동레버와 핀치 아암을 구동시켜주는 구동기어를 순차적으로 동작시켜 주게 하므로 어느 한쪽이 구동될 때 다른 쪽도 구동되지 않게 되도록 하여 주기 때문에 하나의 캠기어만으로 하우징과 핀치아암을 구동시켜 줄 수 있게한 것이다.The present invention has been devised in view of the above points, and the racks having the racks formed at the appropriate portions on both sides are installed on the deck to linearly move by the cam groove curve of the cam gear, and the racks drive the housings according to the movement interval of the slide plates. Since the driving lever for driving the driving lever and the driving pinch for driving the pinch arm are operated in sequence, the driving gear and the pinch arm can be driven by only one cam gear. It is.
이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 제 1 도 및 2에서 보는 바와같이 캠기어(1)에 의해 직선운동하는 슬라이드판(2), 이 슬라이드판의 운동간격에 따라 선택적으로 동작되는 하우징(3) 구동수단과 핀치 아암(4) 구동수단으로 구성되는 것으로 상기 캠기어는 로오딩 모우터(5)의 동작에 의해 회전되는 것으로 그 상면에는 캠홈(11)을 형성하여 상기 슬라이드판의 일단에 착설한 캠핀(12)의 하단을 결합시키고 이 슬라이드판은 양측의 장공(21)을 통해 가이드핀(22)으로 데크(6)에 직선운동할 수 있게 설치하며, 타단의 외측부와 중간의 내측부에는 각기 적정폭으로 래크(23)(23')를 형성하여 래크(23)는 상기의 하우징 구동수단인 구동레버(31)의 내단부측 구동래크(32)와 맞물리게 데크(6)에 축착한 2단 피니언(7)과, 래크(23')는 핀치아암 구동수단인 구동기어(41)와 각각 결합 또는 분리되도록 하며, 상기 구동레버는 양측의 장공(32)을 통해 하우징(3)의 외측면에 지지핀(8)으로 결합시켜 전후진 이동될 수 있게하고 선단부측에는 전동래크(33)를 형성하여 로오딩아암(9)의 기어(9')와 맞물리게 하였으며 상기 구동기어는 타단에 핀치로울러(4')을 축착한 핀치아암(4)의 일단부에 축착하고 원호상으로 뚫은 장공(42)내의 걸이핀(43)과 이 장공에 끼워지게 상기 핀치아암의 일단부에 착설한 걸이핀(43')사이에는 인장 스프링(10)을 걸어주며 상기 2단 피니언기어 상측 일부분(71)과 구동기어의 일부분(41')에는 각기 기어치를 형성하지 않아서 된 것이다.According to the present invention, as shown in FIGS. 1 and 2, the slide plate 2 linearly moved by the cam gear 1, the housing 3 selectively operated according to the movement interval of the slide plate, and the pinch arm ( 4) The cam gear is rotated by the operation of the loading motor 5, and the cam gear 11 is formed on the upper surface of the cam pin 12 formed on one end of the slide plate. The slide plate is installed so that the guide pin 22 can be linearly moved to the deck 6 through the long holes 21 on both sides, and the rack 23 has the appropriate width on the outer side and the middle inner side of the other end, respectively. (23 ') so that the rack (23) is a two-stage pinion (7) affixed to the deck (6) in engagement with the inner end side drive rack (32) of the drive lever (31), which is the housing drive means; The rack 23 'is coupled to or separated from the drive gear 41, which is a pinch arm driving means, respectively. In addition, the driving lever is coupled to the outer surface of the housing (3) by the support pin (8) through the long hole 32 on both sides to move forward and backward, and to form the electric rack 33 on the front end side of the rod arm (9) is engaged with the gear (9) and the driving gear is a hook pin in the long hole (42) which is fixed to one end of the pinch arm (4) in which the pinch roller (4 ') is condensed at the other end and drilled in an arc shape ( 43) and the tension spring 10 is hooked between the hook pin 43 'installed at one end of the pinch arm to fit into the long hole, and the upper portion 71 of the second stage pinion gear 71 and the portion of the drive gear 41. ') Is because they do not form gears.
이와같이 구성되는 본 고안은 제 2 도 및 3 도에서 보는 바와같이 조립되는 것으로 카세트를 삽입하기전의 초기에는 슬라이드판(2)의 래크(23)는 2단 피니언(7)과 맞물려 있고 래크(23')와 구동기어(41)는 서로 격리되어 있게되는 것으로 이러한 상태에서 카세트를 하우징(3)에 삽입하면 로오딩모우터(5)가 동작되어 캠기어(1)가 시계 방향으로 회전되며 이에따라 캠홈(11)에 결합된 캠핀(12)이 캠곡선이 변화에 따라 이동하게 되어 슬라이드판(2)을 우측방향으로 이동시켜 주게 된다.The present invention constructed as described above is assembled as shown in FIGS. 2 and 3, and the rack 23 of the slide plate 2 is engaged with the two-stage pinion 7 at the beginning before inserting the cassette and the rack 23 ' ) And the drive gear 41 are isolated from each other. When the cassette is inserted into the housing 3 in this state, the loading motor 5 is operated so that the cam gear 1 is rotated in the clockwise direction. The cam pin 12 coupled to 11 moves as the cam curve changes, thereby moving the slide plate 2 to the right.
이렇게 되면 래크(23')는 구동기어(41)와 격리되어 있고 래크(23)는 2단 피니어(7)과 맞물려 있으므로 슬라이드판(2)이 우측으로 일정간격 이동되는 동안 핀치아암(4)은 구동되지 않고 피니언(7)만 회전되기 때문에 이 피니언과 맞물려 있는 구동래크(32)에 의해 구동레버(31)가 전진되고 이에따라 선단부의 전동 래크(33)와 맞물려 있는 기어(9')가 회전되어 로오딩아암(9)은 가상선(A)과 같이 회전되므로 카세트 폴레이트를 이동시켜 카세트를 데크(6)에 안착시켜 주게 된다.In this case, the rack 23 'is isolated from the drive gear 41, and the rack 23 is engaged with the second stage pinion 7, so that the pinch arm 4 is moved while the slide plate 2 is moved to the right by a certain distance. Since the pinion 7 is not driven but only the pinion 7 is rotated, the drive lever 31 is advanced by the drive rack 32 engaged with the pinion, so that the gear 9 'engaged with the electric rack 33 at the tip end is engaged. Since the rotating arm 9 is rotated together with the virtual line A, the cassette folate is moved to seat the cassette on the deck 6.
이와같은 동작에 의해 카세트의 안착이 완료되면 이때 래크(23)는 피니언(7)을 지나가게 되어 기어치가 형성되지 않은 부분(71)과 슬라이드판(2)의 평면부분이 교차 하게되므로 이 슬라이드판의 운동력은 피니언(7)에 전달되지 않게 되어 하우징(3)은 동작이 정지되며, 이후 래크(23')는 구동기어(41)와 맞물리게 되기 때문에 이때 부터는 슬라이드판(2)의 운동력이 구동기어(41)와 인장스프링(10)에 의해 핀치 아암(4)에 전달되어 이 아암을 가상선(B)과 같은 위차로 이동시켜 주므로 핀치로울러(4')를 캡스턴 축(H)에 압착시켜 주게 되는 것으로 카세트를 추출할 때에는 상기의 동작이 역순으로 진행되어 모든 부품이 초기의 상태로 되돌아가게 되는 것이다.When the seating of the cassette is completed by the operation as described above, the rack 23 passes through the pinion 7 so that the flat portion of the slide plate 2 and the portion 71 where the gear teeth are not formed are intersected. Since the movement force of the pinion 7 is not transmitted to the pinion 7, the housing 3 is stopped, and since the rack 23 'is engaged with the drive gear 41, the movement force of the slide plate 2 is driven from this time. The pinch roller (4 ') is pressed against the capstan shaft (H) because it is transferred to the pinch arm (4) by the (41) and the tension spring (10) to move the arm at the same level as the virtual line (B). When the cassette is extracted, the above operation is performed in the reverse order, and all the parts are returned to their initial states.
이와같이 작동되는 본 고안은 슬라이드판의 각기 다른 위치에 래크를 형성하여 슬라이드란이 직선운동하는 간격에 따라 하우징과 핀치아암이 순차적으로 구동되게 함과 동시에 이들 중 어느 하나가 구동될 때 다른 하나는 정지되어 있게 하여 주므로 하나의 캠기어만으로도 이들을 구동시켜 줄 수 있게되는 특징이 있으며 이에따라 부품 및 조립공수의 감소는 물론 원가의 절감과 부품감소에 따른 원활한 동작등으로 제품 불량도 해소되는 등 매우 유용한 고안이다.The present invention, which operates as described above, forms a rack at different positions of the slide plate to sequentially drive the housing and the pinch arm at intervals of linear movement of the slide column, while the other stops when one of them is driven. It is designed to drive them with only one cam gear. Therefore, it is very useful to reduce the number of parts and assembly, and to solve the defects of products by reducing the cost and smooth operation according to the reduction of parts. .
