본 고안은 광 디스크 재생용 플레이어에 관한 것으로, 특히 접촉되는 디스크면과 픽업 대물렌즈를 수직으로 맞추는 틸팅 동작을 구현하기 위한 광 디스크 플레이어의 픽업 틸트장치에 관한 것이다.The present invention relates to an optical disc player, and more particularly, to a pickup tilt apparatus of an optical disc player for implementing a tilting operation of vertically aligning a contacted disk surface with a pickup objective lens.
종래 광 디스크 플레이어는 제1도와 제2도에 도시되는 바와같이, 픽업 대물렌즈(1) 일측에 부착된 브라켓(5)과, 상기 브라켓(5)의 일직선 상으로 모터(2)가 부착된 웜(9)과, 상기 웜(9)에 연결되고, 브라켓(5)에 순차적으로 연결 고정되는 웜휠(3), 아이들 기어(4), 캠 기어(6)들과, 상기 회전하는 캠 기어(6)의 측면에 외부로 연장된 틸트레버(7)와, 상기 틸트레버(7)를 아래로 눌려주는 토션스프링(8)으로 구성 되어있다.Conventional optical disc players have a bracket (5) attached to one side of the pick-up objective lens (1) and a worm with a motor (2) attached in a straight line to the bracket (5) as shown in FIGS. (9), a worm wheel (3), idle gear (4), cam gears (6), which are connected to the worm (9) and are connected to the bracket (5) sequentially, and the rotating cam gear (6). It consists of a tilt lever (7) extending to the outside of the side and the torsion spring (8) for pressing the tilt lever (7) down.
이와같이 구성된 종래의 광 디스크 플레이어는 모터(2)에 전원이 인가되어 온상태가 되면, 상기 모터(2)와 일축으로 연결된 워윔(9)이 회전하게 된다.In the conventional optical disk player configured as described above, when power is applied to the motor 2, the watch 9, which is connected uniaxially with the motor 2, is rotated.
이때, 상기 웜(9)의 회전력에 의하여 차례로 웜휠(3), 아이들기어(4), 캠 기어(6)에 차례로 동력이 전달되어 연동된다.In this case, power is sequentially transmitted to the worm wheel 3, the idle gear 4, and the cam gear 6 by the rotational force of the worm 9.
그리고 캠 기어(6)의 회전에 의하여 틸트레버(7)가 힌지를 회전중심으로 상하이동이 가능하게 하여 픽업 대물렌즈(1)의 틸팅동작을 수행케 한다.And by the rotation of the cam gear 6, the tilt lever 7 is able to move the hinge to the center of rotation to perform the tilting operation of the pickup objective lens (1).
이러한 종래의 광 디스크 플레이어은 픽업 대물렌즈(1)는 틸팅동작을 미세하게 하기 위해서는 많은 감속비가 요구될 뿐 아니라, 치차열이 복잡함에 따라 백 리쉬가 증가되어 치차열을 제어하는데 어려운 문제점이 있었다.In the conventional optical disc player, the pickup objective lens 1 requires not only a large reduction ratio in order to make the tilting operation fine, but also has a problem that it is difficult to control the gear train because of the complexity of the gear train.
본 고안의 목적은 종래의 문제점을 감안하여 안출한 것으로, 리드 스크류를 사용하여 슬라이더를 좌우로 이송시켜 캠 기어를 회전시키킴에 따라 디스크면과 픽업 대물렌즈를 수직으로 정확히 맞추어 틸팅 동작을 구현할수 있는 광 디스크 플레이어의 픽업 틸트장치를 제공하는데 있다.The object of the present invention was devised in view of the conventional problems, and the tilting motion can be realized by accurately adjusting the disk surface and the pick-up objective lens vertically as the cam gear is rotated by moving the slider from side to side using a lead screw. The present invention provides a pickup tilt device for an optical disc player.
이하 첨부도면에 의거하여 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration will be described in detail with reference to the accompanying drawings.
본 고안은 제3도, 제4도 및 제5도에 도시되는 바와 같이 좌우측에 힌지(11)가 형성되고, 전면으로 릴트레버(12)가 연장된 픽업 대물렌즈(10)와, 상기 픽업 대물렌즈(10)의 전면에 형성되어 일측이 개구된 브라켓(20)과, 상기 브라켓(20)의 내부에 설치되고, 외부로 부착된 모터(31)와 일체로 회전할 수 있도록 형성된 리드 스크류(30)와, 상기 리드 스크류(30)의 회전에 의하여 전·후로 이송되는 슬라이더(40)와 상기 슬리어더(40)의 접촉에 의해 회전할 수 있도록 축(51)에 고정된 캠 레버(50)와, 상기 틸트레버(12)의 일축에 한쪽이 고정되고 다른 한쪽은 돌출턱(61)에 고정된 스프링(60)으로 구성됨을 그 기술적 구성상의 기본 특징으로 한다.In the present invention, as shown in FIGS. 3, 4, and 5, a hinge 11 is formed at left and right sides, and a pickup objective lens 10 having a reel lever 12 extended to the front, and the pickup objective. A lead screw 30 formed on the front surface of the lens 10 and having one side opened and the lead screw 30 installed in the bracket 20 and rotatably integrated with the motor 31 attached to the outside. And a cam lever 50 fixed to the shaft 51 so as to be rotated by the contact between the slider 40 and the slitter 40 which are conveyed back and forth by the rotation of the lead screw 30. The basic feature of the technical configuration is that one side is fixed to one shaft of the tilt lever 12 and the other side is composed of a spring 60 fixed to the protruding jaw 61.
그리고, 상기 캠 레버(50)의 일단은 틸트레버(12) 하중을 받고 있는 곳에 위치된다.One end of the cam lever 50 is positioned at the place where the tilt lever 12 is loaded.
이와같이 구성된 본 고안은 모터(31)에 전원이 인가되어 온 상태가 되면 상기 모터(31)와 일체로 회전할 수 있도록 연결된 리드 스크류(30)가 회전하게 된다.The present invention configured as described above is connected to the lead screw 30 so as to rotate integrally with the motor 31 when power is applied to the motor 31.
이때 회전하는 상기 리브 스크류(30)의 정 회전에 의해 슬라이더(40)는 우측으로 이송하게 되고, 이송된 슬라이더(40)의 접촉에 의해 캠 레버(50)는 축(51)을 중심으로 회전하면서 한쪽 끝단이 틸트레버(12)를 들어 올리게 된다.At this time, the slider 40 is moved to the right by the forward rotation of the rotating rib screw 30, and the cam lever 50 is rotated about the shaft 51 by the contact of the transferred slider 40. One end lifts up the tilt lever 12.
상기와 같이된 상태에서 모터(31)에 역회전이 걸리면 슬라이더(40)는 리드 스크류(30)를 따라 좌측으로 이동하게 된다.When the reverse rotation is applied to the motor 31 in the above state, the slider 40 moves to the left along the lead screw 30.
이때, 한쪽이 틸트레버(12)의 일축에 고정되고, 다른 한쪽이 돌출턱(61)에 고정된 스프링(60)의 복원력에 의하여 틸트레버(12)가 하부로 내려 오면서 캠 레버(50) 일단을 슬라이더(40)의 측벽에 밀착 시킨다.At this time, one end is fixed to one axis of the tilt lever 12, the other end is lowered by the restoring force of the spring 60 fixed to the projection jaw 61, the tilt lever 12 is lowered to the cam lever 50 once To the side wall of the slider 40.
이에 따라 픽업 대물렌즈(10)는 좌우측에 형성된 힌지를 중심으로 일정각도 회전이 가능하게 된다.Accordingly, the pickup objective lens 10 can be rotated at a predetermined angle about the hinge formed at the left and right sides.
이러한 본 고안은 리드 스크류(30)를 사용하여 슬라이더(40)를 좌.우로 이송시켜 캠기어(50)를 회전시킴에 따라 디스크면과 픽업 대물렌즈(10)를 정확히 수직으로 맞추어 틸팅 동작을 구현할 수 있는 것이다.The present invention implements a tilting operation by accurately moving the disc surface and the pick-up objective lens 10 vertically as the cam gear 50 is rotated by moving the slider 40 to the left and right using the lead screw 30. It can be.
이상에서 살펴본 바와 같이, 본 고안은 리브 스크류를 사용한 간단한 구조로 많은 감속비를 낼 수 있을 뿐만 아니라, 백 리쉬가 적은 구조로 원할한 서보(SERVO)가 가능한 매우 유용한 고안이다.As described above, the present invention is not only able to give a lot of reduction ratios with a simple structure using a rib screw, but also a very useful design that enables a smooth servo (SERVO) with a low backlash structure.
