본 고안은 VTR의 빨리감기와 되감기 혹은 재생시를 구분하여 릴테이블을 회전시킬 수 있도록 하는 아이들러의 2단 구동장치에 관한 것으로 특히, 비디오 테이프의 빨리감기와 되감기 혹은 재생시를 구분하여 아이들러를 상,하로 이동시킨 후 릴테이블을 회전시킬 수 있도록 하는 아이들러의 2단 구동장치에 관한 것이다.The present invention relates to a two-stage driving device of an idler that allows the reel table to be rotated by distinguishing between fast forward and rewind or play of the VTR. In particular, the idler is moved up and down by separating the fast forward and rewind or play of the video tape. It relates to a two-stage drive of the idler to move the reel table after moving.
일반적으로 VTR의 데크에는 서플라이릴 테이블과 테이크업 릴테이블이 설치되어 비디오 카세트가 안착되도록 하고 양측의 릴테이블 사이에 아이들러를 구성하여 아이들러와 접촉된 릴테이블이 회전되도록 하고 있다.In general, the deck of the VTR is provided with a supply reel table and a take-up reel table so that the video cassette is seated, and an idler is formed between the reel tables on both sides to rotate the reel table in contact with the idler.
그러나, 종래의 릴테이블에는 하나의 기어가 구성되어 아이들러의 회전을 하나의 기어로 전달받은 후 다수개의 브레이크에 의한 제동력의 차이로 비디오 테이프가 빨리감기와 되감기 혹은 재생모드로 회전되도록 하였으나, 이러한 아이들러의 구동장치는 회전동력의 손실이 많아지는 결점이 있었다.However, in the conventional reel table, one gear is configured so that the video tape is rotated in the fast rewind and rewind or play mode due to the difference in braking force by a plurality of brakes after the idler rotation is transmitted to one gear. The driving mechanism of has had the drawback that the loss of rotational power increases.
본 고안은 이와 같은 종래의 결점을 감안하여 릴테이블에 2단으로 기어를 형성하고 아이들러를 슬라이드판의 이동에 따라 상, 하로 조절하여 릴테이블을 회전시키므로써 동력손실을 방지할 수 있도록 한 아이들러의 2단구동장치를 제공하기 위한 것으로 이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention, in view of the above-mentioned drawbacks of the conventional idler to form a gear in two stages and adjust the idler up and down in accordance with the movement of the slide plate to rotate the reel table to prevent power loss of the idler It is to provide a two-stage drive device as described in detail by the accompanying drawings as follows.
피니언(4)에 의해 이동하는 슬라이드판(1)과 비디오 카세트가 안착되는 릴테이블(15)이 구성된 VTR데크에 있어서, 고정핀(8)이 삽입된 장홀(7)과 가이드홀(9)이 형성된 이동브라켓(5)의 슬라이드핀(6)을 슬라이드홀(2)에 삽입하고 회전가능하게 힌지(11)를 구성한 조절레버(10)의 선단에는 가이드핀(12)을 설치하여 가이드홀(9)에 삽입하며 릴테이블(15)은 상부기어(16)와 하부기어(17)를 구성하고 조절절버(10)에 의해 아이들러(14)가 상,하로 이동되도록 구성하여서 된 것이다.In the VTR deck comprising the slide plate 1 moved by the pinion 4 and the reel table 15 on which the video cassette is seated, the long hole 7 and the guide hole 9 into which the fixing pin 8 is inserted Insert the slide pin (6) of the formed movable bracket (5) into the slide hole (2) and the guide pin (12) is installed at the tip of the control lever (10) which constitutes the hinge (11) to be rotatable. The reel table 15 is configured to constitute the upper gear 16 and the lower gear 17 and to move the idler 14 up and down by the adjustment lever 10.
이와 같이 구성된 본 고안은 통상적인 작동에 의해 피니언(4)이 회전하여 슬라이드판(1)을 좌측으로 이동시키면 슬라이드핀(6)이 슬라이드홈(2)의 경사면(3)에 접하면서 이동브라켓트(5)를 전진 이동시키고, 전진 이동하는 이동 브라켓트(5)는 장홀(7)에 삽입된 고정핀(8)에 안내됨과 동시에 가이드홀(9)에 삽입된 가이드핀(12)을 하측으로 이동시키는 것이므로 조절레버(10)가 힌지(11)를 중심으로 하향 회전하여 아이들러(14)를 하향이동시킨다.According to the present invention configured as described above, when the pinion 4 rotates to move the slide plate 1 to the left by a normal operation, the slide pin 6 contacts the inclined surface 3 of the slide groove 2 while moving the bracket ( 5) is moved forward, and the moving bracket (5) for moving forward is guided by the fixing pin (8) inserted into the long hole (7) and at the same time to move the guide pin (12) inserted into the guide hole (9) downward Since the control lever 10 is rotated downward about the hinge 11 to move the idler 14 downward.
이때, 하향 이동된 아이들러(14)는 아이들러피니언(13)으로부터 회전을 전달받아 릴테이블(15)의 하부기어(17)에 치합 회전되므로 펠트(18)가 설치된 릴테이블(15)은 재생모드의 회전을 하게 되는 것이다.At this time, since the idler 14 moved downward receives the rotation from the idler pinion 13 and is engaged with the lower gear 17 of the reel table 15, the reel table 15 in which the felt 18 is installed is in the regeneration mode. It will be rotated.
한편, 빨리감기와 되감기시에는 피니언(4)이 통상적인 구성에 의해 역회전을 하여 슬라이드판(1)을 우측으로 이동시켜 슬라이드홈(2)에 삽입된 슬라이드핀(6)을 경사면(3)에 접촉시키면서 이동브라켓트(5)를 후진 이동시키는 것이므로 후진 이동하는 이동브라켓트(5)는 장홀(7)에 삽입된 고정핀(8)에 안내됨과 동시에 가이드홀(9)에 삽입된 가이드핀(12)을 상측으로 안내하여 조절레버(10)를 힌지(11)를 중심으로 상향 회전시킨다.On the other hand, when fast forwarding and rewinding, the pinion 4 reversely rotates according to a conventional configuration to move the slide plate 1 to the right so that the slide pin 6 inserted into the slide groove 2 is inclined. Since the moving bracket 5 moves backward while contacting the moving bracket 5, the moving bracket 5 moving backward is guided by the fixing pin 8 inserted into the long hole 7 and guide pin 12 inserted into the guide hole 9 at the same time. ) To the upper direction to rotate the control lever 10 around the hinge (11).
이때, 상향 회전하는 조절레버(10)는 아이들러피니언(13)과 하부기어(17)에 치합된 아이들러(14)를 상향 이동시켜 아이들러피니언(13)에 치합된 상태로 릴테이블(15)의 상부기어(16)에 치합시킴으로서 아이들러(14)의 회전이 펠트(18)를 통하지 않고 직접 릴테이블(15)을 회전시켜 빨리감기와 되감기 모드의 회전을 얻게 되는 것이다.At this time, the control lever 10 is rotated upward to move the idler 14 engaged to the idler pinion 13 and the lower gear 17 to the upper portion of the reel table 15 in a state of being engaged with the idler pinion 13. By engaging the gear 16, the rotation of the idler 14 is to rotate the reel table 15 directly without passing through the felt 18 to obtain the fast forward and rewind mode rotation.
상기에서와 같이 본 고안은 릴테이블의 펠트 상, 하측에 상부기어와 하부기어를 형성하고 아이들러를 상, 하로 이동시켜 빨리감기와 되감기 혹은 재생시를 구분하여 릴테이블을 회전시키므로써 회전동력의 손실을 최소화할 수 있는 효과가 제공되는 것이다.As described above, the present invention forms an upper gear and a lower gear on the felt upper and lower sides of the reel table, and moves the idler up and down to separate the fast-winding and rewinding or regeneration, thereby rotating the reel table, thereby reducing the loss of rotational power. The effect that can be minimized is provided.
