일반적으로, 레이저디스크플에이어 또는 콤팩트디스크플레이어 같은 광학디스크플레이어에서는 디스크재생동작시 디스크의 기록면과 픽업장치의 거리가 항상 일정하게 유지되어야만 하는데, 디스크제작시의 오차 등에 의하여 디스크의 가장자리가 윗쪽 또는 아랫쪽으로 휘어질 수도 있기 때문에 재생동작시 디스크에 수록된 정보를 정확히 읽어내기 위하여 픽업장치의 기울기를 지속적으로 변화시켜주는 틸팅장치가 장착되어 사용된다.In general, in an optical disc player such as a laser disc player or a compact disc player, the distance between the recording surface of the disc and the pickup device must be kept constant at all times during disc reproducing operation, and the edge of the disc may be upward or downward due to errors in disc production. Since it may be bent, a tilting device that continuously changes the inclination of the pickup device is used in order to accurately read the information recorded on the disk during the playback operation.

이와 같은 픽업틸팅장치의 종래 구조는 통상적으로 제1도 및 제2도에 도시된 바와 같이, 픽업장치가 설치되는 픽업가이드(10) 일측에 틸팅모터(12)를 설치하고, 상기 픽업가이드(10)의 저면에는 상기 틸팅모터(12)의 구동력을 받아 회동하면서 픽업가이드(10)의 기울기를 조절하는 경사진면을 갖는 노브(Knob)(14)를 설치하여 픽업장치의 기울기를 조절할 수 있도록 되어 있다.In the conventional structure of such a pickup tilting device, as shown in FIGS. 1 and 2, a tilting motor 12 is installed on one side of a pickup guide 10 on which a pickup device is installed, and the pickup guide 10 On the bottom of the) is installed by a knob (Knob) (14) having an inclined surface for adjusting the inclination of the pickup guide 10 while rotating in response to the driving force of the tilting motor 12 to be able to adjust the inclination of the pickup device have.

그러나, 이와같은 종래의 픽업틸팅장치에서는 별도의 틸팅모터(12)가 적용되어야 하며, 틸팅모터(12)로부터 발생되는 동력을 높이조정 노브까지 전달하기 위해서는 여러개의 전동기어(16)가 설치되어야 하기 때문에 구조가 복잡해지고 제품의 무게가 무거워진다는 문제점이 있었다.However, in the conventional pick-up tilting device, a separate tilting motor 12 should be applied, and in order to transfer the power generated from the tilting motor 12 to the height adjusting knob, several electric gears 16 should be installed. Therefore, there is a problem that the structure is complicated and the weight of the product becomes heavy.

본 발명은 이와 종래의 문제점을 해결하기 위한 것으로, 양면재생용 레이저디스크플레이어에서 디스크클램프장치를 구성하는 클램퍼암(Clamper Arm)과 픽업가이드를 결합하여 로딩모터의 구동에 의한 무빙플레이트의 직선이동에 의하여 상하 승강운동하는 클램프장치의 여유공간과 디스크클램프동작후의 로딩모터의 여분의 동작을 이용하여 픽업장치가 설치된 픽업가이드의 기울기를 효과적으로 조절할 수 있도록 새로운 형태의 양면재생용 레이저디스크플레이어의 픽업틸팅장치를 제공하고자 하는데 목적이 있다.The present invention is to solve the above problems, in combination with the clamper arm (pickup guide) constituting the disk clamp device in the laser disk player for double-sided reproduction to the linear movement of the moving plate by the driving of the loading motor Pick-up tilting device of a new type double-sided laser disc player for effective adjustment of the inclination of the pick-up guide in which the pick-up device is installed by using the free space of the clamp device that moves up and down and the extra motion of the loading motor after the disk clamp operation. The purpose is to provide.

이하, 첨부된 도면에 의하여 본 발명의 실시예를 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail.

본 발명은 제3도에 도시된 바와 같이, 양면재생용 레이저디스크플레이어에서 픽업장치(30)의 반전동작을 가이드하는 픽업가이드(32) 상부의 선단 양측에 일정한 기울기로 경사진 안내공(34)을 갖는 결합편(36)을 일체로 형성하고, 클램프장치(38)를 구성하는 클램퍼암(40)의 후단 양측으로부터는 상기 안내공(34)에 끼워질 수 있도록 안쪽으로 돌출된 안내돌기(42)를 갖는 연결리브(44)를 형성하며, 로딩모터(46)가 내부 마이컴과 전기적으로 연결되어 디스크의 로당완료후 틸팅동작을 위해 정역회동될 수 있도록 구성하여 된 특징을 갖는다.As shown in FIG. 3, the guide hole 34 inclined at a constant inclination on both sides of the tip of the pickup guide 32 for guiding the reversal operation of the pickup device 30 in the laser disk player for double-sided reproduction. The guide piece 42 protruding inwardly to be fitted into the guide hole 34 from both sides of the rear end of the clamper arm 40 constituting the coupling piece 36 having an integral portion, and constituting the clamp device 38. It forms a connecting rib 44 having a), the loading motor 46 is electrically connected to the internal microcomputer and has a feature that is configured to be forward and reverse rotation for the tilting operation after the completion of the per row of disk.

이와 같은 본발명에서 픽업가이드(32) 하부의 횡방향 중심에는 회동축(48)을 끼워설치하고, 상기 클램프장치(38)를 구성하는 클램퍼암(40)의 양측면으로부터는 가이드봉(50)을 형성하여 로딩모터(46), 전동기어(52) 및 이송기어(54)로 이루어지는 통상의 로딩수단(56)의 구동에 의하여 전후 직선이동되는 무빙플레이트(58)상에 형성된 캠공(60)에 끼워지도록 한다.In the present invention, the pivot shaft 48 is fitted to the transverse center of the lower portion of the pickup guide 32, and guide rods 50 are provided from both sides of the clamper arm 40 constituting the clamp device 38. And a cam hole 60 formed on the moving plate 58 which is linearly moved back and forth by driving the conventional loading means 56 including the loading motor 46, the electric gear 52, and the transfer gear 54. To lose.

상기한 구조를 갖는 본 발명의 작용은 다음과 같다.The operation of the present invention having the above structure is as follows.

제4도에 도시된 바와 같이, 클램프장치(38)로부터 돌설된 가이드봉(50)이 무빙플레이트(58)에 형성된 캠공(60)의 가장 높은 위치에 위치된 초기 상태에서 사용자가 디스크트레이에 디스크를 탑재시킨 후 밀어넣으면, 로딩수단(56)을 구성하는 로딩모터(48)의 구동력에 의하여 로딩동작이 이루어지는데, 이와 같은 로딩모터(46)의 동력이 무빙플레이트(58)에 전달됨에 따라 무빙플레이트(58)가 후방으로 직선이동되고, 그 결과 클램퍼암(40)은 하강하여 턴테이블상에 안착된 디스크를 클램핑하여 A면 재생준비가 완료된다.As shown in FIG. 4, in the initial state in which the guide rod 50 protruding from the clamping device 38 is located at the highest position of the cam hole 60 formed in the moving plate 58, the user puts the disc in the disc tray. After the mounting and pushing, the loading operation is performed by the driving force of the loading motor 48 constituting the loading means 56, the power of such a loading motor 46 is transferred to the moving plate 58 The plate 58 is linearly moved rearward, and as a result, the clamper arm 40 descends to clamp the disc seated on the turntable, thereby completing the A-side regeneration preparation.

이때, 클램퍼(62)내의 자석과 턴테이블내에 설치된 금속판 사이에 작용하는 인력에 의하여 클램프장치(38)가 캠공(60)상의 A면 재생위치(64)에 도달되기 전에 이미 디스크의 클램핑동작이 완료된다. 이에 따라, 가이드봉(50)이 상기 캠공(60)상의 A면 재생위치(64)에 도달된 상태에서는 클램퍼(62)와 클램퍼암(40)이 서로 분리된 상태가 되며, 이때, 발생되는 클램퍼암(40)과 클램퍼(62) 사이의 여유공간에 의하여 클램퍼암(40)이 일정각도 만큼 회동하여도 클램퍼(62)의 디스크 클램핑작용에 어떠한 영향을 미치지 않게 된다.At this time, the clamping operation of the disk is already completed before the clamp device 38 reaches the A surface regeneration position 64 on the cam hole 60 by the attraction force acting between the magnet in the clamper 62 and the metal plate installed in the turntable. . Accordingly, when the guide rod 50 reaches the A surface regeneration position 64 on the cam hole 60, the clamper 62 and the clamper arm 40 are separated from each other. The clearance between the arm 40 and the clamper 62 does not affect the disk clamping action of the clamper 62 even when the clamper arm 40 is rotated by a predetermined angle.

이 같은 상태에서 픽업장치의 틸트센서에서 읽어낸 디스크의 기록면과 픽업장치(30) 사이의 거리오차신호가 미이컴을 통하여 로딩모터(46)에 인가되어, 그 로딩모터(46)가 정역회동됨에 따라 무빙플레이트(58)가 전후방향으로 짧게 이동되며, 이때, 제5도에 도시된 바와 같이, 상기 클램퍼암(40) 후단에 형성된 연결리브(44)상의 안내돌기(42)가 픽업가이드(32) 선단에 형성된 안내공(34)의 기울기를 따라 왕복운동하면서 픽업 가이드(32) 전체가 회동축(48)을 중심으로 하여 회동되면서 픽업장치(30)의 틸팅동작이 수행된다.In such a state, a distance error signal between the recording surface of the disc read out by the tilt sensor of the pickup device and the pickup device 30 is applied to the loading motor 46 through the micom, and the loading motor 46 is reversely rotated. As a result, the moving plate 58 is shortly moved in the front-rear direction. At this time, as illustrated in FIG. 5, the guide protrusion 42 on the connecting rib 44 formed at the rear end of the clamper arm 40 is pick-up guide 32. Tilting operation of the pickup device 30 is performed while the entire pickup guide 32 is rotated about the pivot shaft 48 while reciprocating along the inclination of the guide hole 34 formed at the tip.

한편, 디스크의 B인 재생시에는 제6도에 도시된 바와 같이, 무빙플레이트(58)의 후방이송동작에 의하여 클램프장치(38)의 가이드봉(50)이 캠공(60)상면 B인 클램프위치(66)에 도달되면서 클램퍼(62)가 디스크의 B면을 클램프하게 되며, 이 상태에서 클램퍼암(40)은 다시 상승하여 캠공(60)상의 B면 재생위치(68)로 올라온다.On the other hand, at the time of reproducing B of the disc, as shown in FIG. 6, the guide bar 50 of the clamping device 38 is clamped at the upper surface B of the cam hole 60 by the rearward movement of the moving plate 58. 66, the clamper 62 clamps the B surface of the disk, and in this state, the clamper arm 40 is raised again to the B surface regeneration position 68 on the cam hole 60.

이때, 다시 클램퍼(62)와 클램퍼암(40) 사이에 여유공간이 발생하여 클램퍼암(40)이 일정기울기로 회동한다 하더라도 클램퍼(62)의 디스크클램핑동작에 영향을 미치지 않게 된다.At this time, a free space is generated between the clamper 62 and the clamper arm 40 so that the clamping arm 40 does not affect the disk clamping operation of the clamper 62 even when the clamper arm 40 rotates with a predetermined tilt.

이와 같은 상태에서 클램퍼암(40)이 디스크의 A면 재생시의 틸팅동작과 동일하게 움직이면서 픽업가이드(32) 전체를 그 회동축(48)을 중심으로 회전시켜 픽업장치(30)의 틸팅각도를 조정하는 것이다.In this state, the clamper arm 40 moves in the same manner as the tilting operation when playing the A side of the disc, while rotating the entire pickup guide 32 about its pivot shaft 48 to adjust the tilting angle of the pickup device 30. It is.

이와 같은 본 발명을 적용하면 픽업장치의 틸팅동작이 클램프장치를 구성하는 클램퍼와 클램퍼암 사이의 여유공간과 로딩모터의 작용에 의하여 이루어짐에 따라 별도의 틸팅모터 및 틸팅모터의 동력을 전달하는 동력전달장치 등의 설치가 필요없게 되므로 내부구조가 간단해지며 제품의 무게를 현저히 줄일 수 있다는 효과가 있다.Applying the present invention as described above, the tilting operation of the pick-up device is performed by the action of the free space between the clamper and the clamper arm constituting the clamp device and the loading motor power transmission for transmitting the power of the separate tilting motor and tilting motor Since the installation of the device is not necessary, the internal structure is simplified and the weight of the product can be significantly reduced.
