본 고안은 레이저를 이용한 콤팩트 디스크 플레이어등과 같은 기기에 있어서, 레이저의 발생장치인 픽업의 유동을 방지하기 위한 픽업 고정장치에 대한 것이다.The present invention relates to a pickup fixing device for preventing the flow of pickup, which is a generator of laser, in a device such as a compact disc player using a laser.

종래의 이러한 기기들의 픽업 고정장치는 픽업 몸체에 직접 고정하거나 또는 픽업 주변 브라켓트를 고정하는 방법을 주로 사용하였는데, 이러한 방법에서는 고정장치들이 픽업을 고정하는 위치가 한정되어 있는 결점이 있었다.Conventional pick-up fixtures of such devices mainly use a method of directly fixing the pick-up body or fixing a bracket around the pick-up body. In this method, there are drawbacks in that the fixing devices have a limited position for fixing the pick-up.

본 고안은 이와 같은 결점을 해결하기 위해 픽업 구동기어를 레버로 고정하는 방법을 사용하여 픽업이 어느 위치에 있어도 고정이 가능하도록 고안한 것으로 첨부 도면에 의거 상술하면 다음과 같다.The present invention is designed to be able to be fixed at any position of the pickup using a method of fixing the pickup drive gear with a lever in order to solve such a defect as described above according to the accompanying drawings.

픽업(1)을 착설한 이동판(2)이 안내봉(3)을 따라 이동되게 설치함에 있어서, 이동판(2)의 측면에 랙기어(4)를 형성하여 구동기어(5)(5')(5")중 구동기어(5")와 치합하고, 측방에는 비틀림스프링(6)에 의해 탄발되는 구동판(7)을 지지편(8)(8') 사이에 끼워지게 착설하고, 구동판(7) 선단의 고정핀(7')에는 측(S)을 중심으로 회전되는 고정레버(9)의 장공(10)이 뚫어진 후단부(9')를 결착하고, 선단부(9")에는 구동기어(5')와 치합되는 치(11)를 형성하여서 된 것이다.In installing the movable plate 2 on which the pickup 1 is mounted to move along the guide rod 3, the rack gear 4 is formed on the side of the movable plate 2 to drive the drive gears 5 and 5 '. (5 ") is engaged with the drive gear (5"), and installs the drive plate (7) which is pushed by the torsion spring (6) between the support pieces (8) (8 ') on the side, and drives On the fixing pin 7 'at the tip of the plate 7, the rear end 9' through which the long hole 10 of the fixing lever 9 rotated about the side S is drilled, and at the tip 9 ". It is made by forming the tooth 11 which meshes with the drive gear 5 '.

미설명부호 "12"는 구동판을 움직여주기 위한 도구결합부이고, "13.13'"는 비틀림 스프링의 단부를 고정하는 고정핀이다.Reference numeral "12" is a tool coupling for moving the drive plate, "13.13 '" is a fixing pin for fixing the end of the torsion spring.

이와 같이 된 본 고안의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention as described above is as follows.

픽업(1)이 착설된 이동판(2)을 고정시키고져 할때에는 드라이버등과 같은 도구의 끝을 결합부(12)에 끼워서 구동판(7)을 제2도 (a)에서와 같이 화살표 방향으로 이동시켜주면 고정핀(7')이 장공(10)내에서 이동되면서 고정레버(9)를 움직여 주므로 고정레버(9)는 축(S)을 중심으로 회전되어 그 선단의 치(11)가 구동기어(5')에 치합되면서 구동기어(5')가 회전되지 못하게 고정시켜 주게 되므로 결국 각 구동기어(5)(5')(5")가 회전되지 못하게 되어 이동판(2)이 고정되는 것이다.When the pick-up 1 is fixed on the moving plate 2, the end of a tool such as a screwdriver is inserted into the engaging portion 12 so that the drive plate 7 is moved in the direction of the arrow as shown in FIG. When moving to the fixed pin (7 ') is moved in the long hole (10) to move the fixed lever (9), the fixed lever (9) is rotated about the axis (S) so that the teeth 11 of the tip Since the driving gear 5 'is fixed to the driving gear 5' to prevent the driving gear 5 'from rotating, the driving plate 5 is fixed because the driving gear 5, 5', 5 "is not rotated. Will be.

이렇게 이동판(2)을 고정시킬 수 있게 되므로 이동판(2)은 제2도 (a)의 가상선(a)(b)에서 보는 바와 같이 어느 위치로 이동이 되어도 랙기어(4)가 구동기어(5")와 치합된 상태로 되기 때문에 항상 이동판(2)의 이동 위치에 관계없이 고정시켜줄 수 있게 되는 것이며, 또 이러한 고정상태에서는 비틀림 스프링(6)의 탄발력은 구동판(7)이 이동된 방향으로 작용하게 되어 고정레버(9)는 임의로 구동기어(5')에서 격리되지 않게 되고, 이에 따라 이동판(2)의 고정상태는 확실하게 되어 유동이 방지된다.Since the movable plate 2 can be fixed as described above, the rack gear 4 is driven at any position as the movable plate 2 is moved as shown in the virtual line (a) (b) of FIG. Since it is engaged with the gear 5 ", it is possible to always fix it regardless of the moving position of the moving plate 2, and in this fixed state, the elastic force of the torsion spring 6 is the driving plate 7 This acts in the moved direction so that the fixed lever 9 is not isolated from the drive gear 5 'arbitrarily, whereby the fixed state of the movable plate 2 is secured, thereby preventing the flow.

또한, 이동판(2)을 이동시키고져 할때에는 도구를 결합부(12)에 끼워 구동판(7)을 제2도 (b)에서와 같이 화살표 방향으로 이동시켜주면 그 선단의 고정핀(7')이 장공(10)내에서 이동되면서 고정레버(9)의 후단부(9')를 밀어주므로 이 고정레버(9)는 축(S)을 중심으로 회동되어 그 선단부가 구동기어(2')에서 격리되기 때문에 구동기어(2')는 회전이 가능하게 되므로, 이에 따라 구동력이 구동기어(2)(2')(2")들에 의해 랙기어(4)에 전달되어 이동판(2)의 이동이 가능하게 되는 것이며, 이때 비틀림 스프링(6)의 탄발력은 구동판(70이 이동된 방향으로 작동하게 되므로 고정레버(9)는 제2도 (b)와 같은 위치로 회동된 상태에서 고정되기 때문에 구동기어들의 작동에 장애가 되지 않도록 하여 준다.In addition, when the moving plate 2 is to be moved, the tool is inserted into the engaging portion 12 and the driving plate 7 is moved in the direction of the arrow as shown in FIG. 2 (b). ') Is moved in the long hole 10 and pushes the rear end 9' of the fixed lever 9, so that the fixed lever 9 is rotated about the axis S so that its front end is driven by the driving gear 2 '. Since the driving gear 2 'is rotatable, the driving force is transmitted to the rack gear 4 by the driving gears 2, 2' and 2 ", so that the driving gear 2 'is rotatable. In this case, the elastic force of the torsion spring 6 is operated in the direction in which the driving plate 70 is moved, so that the fixing lever 9 is rotated to the position as shown in FIG. It is fixed at, so that it does not interfere with the operation of the drive gear.

이와 같이 본 고안은 비틀림스프링(6)으로 탄발되게 착설된 구동판(7)의 조작으로 고정레버(9)를 동작시켜 픽업(1)이 착설된 이동판(2)의 유동을 효과적으로 방지할 수 있도록 하여주는 매우 실용적인 고안이다.As such, the present invention can effectively prevent the flow of the movable plate 2 on which the pickup 1 is mounted by operating the fixing lever 9 by the operation of the driving plate 7 elastically installed with the torsion spring 6. It is a very practical design.
