본 고안은 비디오 디스크 플레이어에 있어서 기계식 비디오 디스크의 클램핑 장치의 부품의 간소화를 꾀하여 디스크의 하강을 위한 별도의 구동 모우터를 설치할 필요없이 디스크를 정확하게 스핀들 모우터에 안착시킴과 동시에 클램핑이 될 수 있도록 한 기계식 비디오 디스크의 클램핑장치에 관한 것이다.The present invention aims to simplify the components of the mechanical video disc clamping device in the video disc player so that the disc can be accurately mounted on the spindle motor and clamped without the need to install a separate drive motor for the disc lowering. A clamping device for a mechanical video disc.

일반적으로 모우터의 구동에 의하여 디스크를 실어나르는 플레이어에 있어서 디스크가 트레이에 실린후 안으로 삽입된 다음 스핀들 모우터에 얹혀지게 된다.In general, in a player carrying a disc by driving a motor, the disc is loaded in a tray and then inserted into the spindle motor.

따라서 종래에는 구동모우터에 의하여 디스크 안착과 클렘핑이 이루어져 별도의 구동 모우터를 설치하여야 하는 번거로움과 아울러 부품의 증가로 인한 비디오 디스크 플레이어의 소형화 하는데 문제점이 있었다.Therefore, in the related art, the disk mounting and clamping is performed by the drive motor, and there is a problem in miniaturization of the video disc player due to the increase of parts and the inconvenience of installing a separate drive motor.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 별도의 구동 모우터를 설치한 필요없이 캠기어와 픽업의 구동으로 디스크의 하강과 동시에 클램핑이 완료될 수 있도록 안출한 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves the conventional problems as described above, without the need to install a separate drive motor to drive the cam gear and the pickup to descend the disk at the same time to complete the clamping. The explanation is as follows.

랙크(1)상부에 랙(9)을 형성하여 캠기어(5)와 치합하는 픽업브라켓(8)이 설치되고 트레이 고정축(11)에 축착된 디스크 호울더(12)가 상하 구동될 수 있도록 트레이(10)가 설치된 통상의 비디오 디스크 클램핑장치에 있어서 클램프 브라켓(2)우측 하단에 클램프(3)를 설치하고 좌측 양단에 고정홈(16)을 천공하여 캠기어(5)를 형성한 캠기어축(4)양단에 회전돌기(7)를 가진 회전캠(6)을 각각 연설하고 상기 고정홈(16)과 회전돌기(7)사이에 인장스프링(17)을 걸어 고정하여 동축(15)을 중심으로 클램프 브라켓(2)이 상하 구동될 수 있게 하며 픽업 브라켓(8)의 랙(9)과 캠기어(5)를 치합시킴과 동시에 트레이(10)가 전후 습동에 의해 회전돌기(7)에 트레이고정(11)선단부가 하방에 위치하여 스위치(13)를 작동시킬 수 있도록 구성한 것으로 도면중 미설명부호(14)는 디스크이고, (18)은 힌지부, (19)는 힌지봉이다.The rack 9 is formed on the rack 1 so that the pick-up bracket 8 which meshes with the cam gear 5 is installed and the disk holder 12 which is fixed on the tray fixing shaft 11 can be driven up and down. In a conventional video disc clamping device provided with a tray 10, a cam gear having a cam gear 5 formed by installing a clamp 3 at a lower right side of a clamp bracket 2 and drilling holes 16 at both ends thereof. The rotating cam 6 having the rotating projection 7 at each end of the shaft 4 is extended, and the coaxial 15 is fixed by hanging the tension spring 17 between the fixing groove 16 and the rotating projection 7. The clamp bracket 2 can be driven up and down at the center, and the rack 9 and the cam gear 5 of the pickup bracket 8 are engaged with each other, and the tray 10 is moved to the rotary projection 7 by front and rear sliding. The tip of the tray fixing 11 is located below to operate the switch 13. In the drawing, reference numeral 14 denotes a disk, 18 is a hinge part and 19 is a hinge rod.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

트레이(10)가 이젝트된 상태에서 디스크(14)를 디스크 호울더(12)위에 가볍게 올려 놓은 뒤 통상의 방법으로 트레이(10)를 손으로 밀어 넣으면 트레이고정축(11)이 회전돌기(7)의 하방으로 접촉하게 됨과 동시에 트레이(10)가 스위치(13)와 접촉하여 로딩이 되었음을 알리는 순간 픽업브라겟(8)이 구동하기 시작하면서 픽업브라켓(8)위의 랙(9)과 캠기어(5)와의 치합에 의해 캠기어축(4)이 회전을 시작하게 되고 동시에 회전돌기(7)와 접촉하고 있던 트레이고정(11)도 아래방향으로 회전하여 그림 제 2 도에서와 같이 택크(1)에 고정된 힌지부(18)에 의해 디스크홀더(12)가 일체로 형성된 트레이고정축(11)이 회전하면서 디스크(14)를 트레이(10)위에 안착하게 되는데 이때 캠기어축(4)에 따라 클램프 브라켓(2)은 캠기어(5)의 특유 곡선을 따라 클램프브라켓(2)과 회전돌기(1)사이에 있는 인장스프링(17)의 인장력에 의해 클램프(3)가 디스크(14)위에 얹혀지게되어 클램핑동작 완료상태가 되는것이며 디스크(14)취출시는 상기의 동작 역순으로 픽업 브라켓(8)이 디스크(14)의주연쪽으로 이동하며 랙(9)에 의해 회전캠(6)이 역회전하면서 트레이 고정(11)을 들어올려 디스크 호울더(12)를 승강시킴과 동시에 회전돌기(7)가 승강하여 클램프 브라켓(2)도 인장스프링(17)의 인장력에의해 처음 상태로 클램프 브라켓(2)이 상승하여 클램프 브라켓(2)에 부착된 클램프(3)도 상승한다.When the tray 10 is ejected and the disk 14 is lightly placed on the disk holder 12 and the tray 10 is pushed by hand in the usual manner, the tray fixing shaft 11 rotates the projection 7. As soon as the tray 10 is in contact with the switch 13 and the tray 13 is in contact with the switch 13, the pickup bracket 8 starts to drive, the rack 9 and the cam gear on the pickup bracket 8 are driven. 5) The cam gear shaft 4 starts to rotate by engagement with the tray. At the same time, the tray fixing 11, which has been in contact with the rotary projection 7, also rotates downward, so that the tag 1 can be rotated as shown in FIG. The tray fixing shaft 11 in which the disc holder 12 is integrally formed by the hinge portion 18 fixed to the rotary shaft 11 rotates to seat the disc 14 on the tray 10. At this time, according to the cam gear shaft 4 The clamp bracket (2) is a clamp bracket (2) and the rotating projection (1) along the characteristic curve of the cam gear (5) The clamp 3 is placed on the disk 14 by the tension force of the tension spring 17, and the clamping operation is completed. When the disk 14 is taken out, the pickup bracket 8 moves the disk in the reverse order. Moving toward the periphery of the (14), the rotary cam (6) by the rack (9) to rotate the tray fixed (11) while lifting the disc holder (12) while lifting the rotary projection (7) The clamp bracket 2 also rises in the initial state by the tension force of the tension spring 17, and the clamp 3 attached to the clamp bracket 2 also rises.

상술한 바와같이 본 고안은 캠기어와 픽업의 구동으로 디스크의 하강과 동시에 클램핑이 완료되도록 하는 장치로써 별도의 구동 모우터를 설치할 필요가 없이 부품의 간소화를 꾀하여 제품의 소형화 및 원가 절감에 지대한 효과를 볼 수 있는 유용한 고안인 것이다.As described above, the present invention is a device that allows the clamping to be completed at the same time as the disk is lowered by the drive of the cam gear and the pickup. It is a useful design to see.
