본 발명은 광디스크 재생기의 픽업안내장치에 관한 것으로 특히 픽업안내장치가 보다 단순하게 형성되도록 한 것이다.The present invention relates to a pickup guide device for an optical disc player, and more particularly, to allow a pickup guide device to be formed more simply.

종래 광디스크 재생기의 픽업안내장치와 그 주변부는 제1도에 도시된 바와 같이 디스크장착부에 장착되어 회전하는 디스크(1)에서 기록을 독출하는 픽업장치(2)와, 상기 픽업장치가 착설되고 타이밍기어(3, 4) 및 타이밍롤러(5, 6)에 권취되어 픽업을 이송하는 타이밍벨트(7)와, 상기 타이밍밸트가 권취하는 타이밍기어 등을 회동시키는 구동풀리(8) 및 구동모우터(9)로 구성되었다.A pickup guide device and its peripheral portion of a conventional optical disc player are mounted on a disc mounting portion as shown in FIG. 1, and a pickup device 2 for reading out a record from a rotating disc 1, and the pickup device is mounted and timingd. A timing belt 7 wound around the gears 3 and 4 and the timing rollers 5 and 6 to transfer the pickup, a drive pulley 8 and a driving motor for rotating the timing gear and the like wound by the timing belt; 9).

그리고 상기 픽업장치는 자신의 내부를 관통하는 안내축(10)에 의하여 직접 안내를 받으며 안내면(11)을 이동하는 가이드롤러(12)에 의하여 간접 안내를 받는다.The pickup device is directly guided by the guide shaft 10 penetrating the inside thereof, and is indirectly guided by the guide roller 12 moving the guide surface 11.

이상과 같은 구성을 가지는 종래 발명의 부가적인 설명과 이에 따르는 문제점을 이하에서 기술한다.Additional descriptions of the related art and problems associated with the above-described configuration will be described below.

광디스크 재생기가 재생신호를 받아 디스크(1)가 회전하게 되면 구동풀리(8) 및 구동모우터(9)에 의하여 타이밍벨트(7)가 회전되어 진다.When the optical disc player receives the reproduction signal and the disc 1 rotates, the timing belt 7 is rotated by the drive pulley 8 and the drive motor 9.

타이밍벨트가 회전하면 타이밍벨트(7)에 착설된 픽업장치(2)가 중립위치로부터 디스크(1)의 A면 재생시작점으로 이동하면서 디스크의 A면 기록을 독출을 시작한다.When the timing belt rotates, the pickup device 2 mounted on the timing belt 7 starts reading the A side record of the disc while moving from the neutral position to the A side reproduction start point of the disc 1.

상기 동작으로 디스크(1) A면의 재생이 끝나면 계속되는 구동풀리(8) 및 구동모우터(9)의 동작으로 타이밍벨트(7)가 회전하면서 픽업장치(2)는 자동으로 디스크의 B면 재생시작점으로 이동되어 B면의 기록을 독출한다.The pickup device 2 automatically plays back the B side of the disc while the timing belt 7 is rotated by the operation of the driving pulley 8 and the driving motor 9 which continue after the reproduction of the A side of the disc 1 by the above operation. It moves to the starting point and reads the record on the B side.

A면과 B면의 재생이 모두 끝나면 구동풀리(8)의 역회전으로 픽업장치(2)는 다시 A면 재생시작점으로 복귀하게 되며, B면 재생중 A면 재생모드를 주었을 때도 상기와 동일한 동작을 진행된다.After the regeneration of the A side and the B side is completed, the pickup device 2 returns to the A side regeneration start point by the reverse rotation of the driving pulley 8, and the same operation as described above when the A side regeneration mode is given during the B side regeneration. Proceeds.

그러나 상기한 종래의 구성에서를 픽업장치를 이송하기 위해서 타이밍기어, 타이밍롤러, 타이밍밸트 등의 부품을 구비해야 하므로 구성이 복잡하며 조립성이 좋지 않아 제작에 많은 시간을 소용하는 것을 물론 장시간 사용함에 따라 타이밍벨트의 늘어짐이 발생하여 응답속도의 지연 등을 가져오는 문제점이 있다.However, in order to transfer the pick-up device in the above-described conventional configuration, it is necessary to include components such as a timing gear, a timing roller, a timing belt, etc., and thus the configuration is complicated and the assembly is not good. Accordingly, there is a problem that a sagging of the timing belt occurs, resulting in a delay in response speed.

본 발명은 이러한 종래의 문제점들을 해결하기 위한 것으로 광디스크의 A면 상부에서 B면 상부까지 이어진 모노레일과, 상기 모노레일을 따라 양면의 상부에서는 정보를 독출하고 정보 독출 후에는 오토리버스 되도록 픽업장치를 이송하는 이송수단과, 상기 이송수단에 의해 이송되는 픽업장치를 안정되도록 안내하는 안내수단을 구비함으로써 픽업장치가 보다 단순하게 형성되도록 하는 데 목적이 있다.The present invention is to solve the above-mentioned problems, and the monorail extending from the top of the A surface to the top of the B surface of the optical disc, and the pick-up device for reading information on the upper side of both sides along the monorail and autoreversing after reading the information. An object of the present invention is to provide a simpler pickup device by providing a transfer means and guide means for guiding the pick-up device conveyed by the transfer means to be stable.

본 발명 광디스크 재생기의 픽업안내장치는 제2도에 도시된 바와 같이 광디스크(101)의 A면 상부에서 B면 상부까지 이어진 모노레일(201)과, 상기 모노레일을 따라 양면의 상부에서는 정보를 독출하고 정보 독출 후에는 오토리버스되도록 픽업장치(102)를 이송하는 이송수단과, 상기 이송수단에 의해 이송되는 픽업장치을 안정되도록 안내하는 안내수단으로 구성된다.As shown in FIG. 2, the pickup guide apparatus of the optical disc player of the present invention reads information from a monorail 201 extending from the top of the A side to the top of the B side of the optical disc 101, and from the top of both sides along the monorail. After the reading is composed of a conveying means for conveying the pick-up device 102 to be autoreversed, and a guide means for guiding the pick-up device conveyed by the conveying means to be stable.

그리고 상기 전구간에 걸쳐 일측면에 레크(202)가 형성되고 타일측면에는 평편한 안내면(203)이 형성된다.And the rake 202 is formed on one side over the entire period, and the flat guide surface 203 is formed on the tile side.

그리고 상기 이송수단은 모노레일은 모노레일의 레크가 치합하는 구동기어(204)와, 상기 구동기어에 회전동력을 전달하는 구동모우터(205)로 구성된다.In addition, the conveying means is composed of a drive gear 204 to which the monorail legs are engaged, and a drive motor 205 for transmitting rotational power to the drive gear.

그리고 상기 안내수단은 직접안내하기 위하여 픽업장치를 관통하는 안내축(206)과, 간접 안내하기 위하여 모노레일의 안내면을 따라 이동하는 안내롤러(207)로 구성된다.The guide means comprises a guide shaft 206 penetrating the pick-up device for direct guidance, and a guide roller 207 moving along the guide surface of the monorail for indirect guidance.

이상과 같은 구성을 가지는 본 발명의 부가적인 설명과 이에 따르는 효과를 이하에서 기술한다.Additional description of the present invention having the above configuration and the effects thereof will be described below.

광디스크 재생기가 재생신호를 받아 디스크(101)가 회전하게 되면 구동모우터(205)에 의하여 구동기어(204)는 래크(202)와 맞물려 이동하게 된다.When the optical disc player receives the playback signal and the disc 101 rotates, the drive gear 204 is engaged with the rack 202 by the drive motor 205.

픽업장치(102)와 고착되어 있는 구동기어(204)가 이동하면 모노레일(201)에 구동기와 함께 착설되어 있는 상기 픽업장치는 중립위치로 부터 디스크(101)의 A면 재생시작점으로 이동하면서 디스크의 A면 기록 독출을 시작한다.When the drive gear 204 fixed to the pick-up device 102 is moved, the pick-up device mounted on the monorail 201 together with the driver moves from the neutral position to the start point of the A-plane playback of the disc 101, Begin reading side A records.

이때 픽업장치를 관통하는 안내축(206)은 픽업장치(102)를 직접안내하며 안내롤러는 (207)은 안내면(203)을 따라 이동하여 픽업장치가 상하 좌우로 흔들리는 것 등을 간접적으로 방지한다.At this time, the guide shaft 206 penetrating the pickup device guides the pickup device 102 directly, and the guide roller 207 moves along the guide surface 203 to indirectly prevent the pickup device from shaking up, down, left, and right. .

상기 동작으로 디스크(101) A면의 재생이 끝나면 계속되는 구동모우터(205)의 동작으로 구동기어(204)가 회전하면서 픽업장치(102)는 자동으로 디스크의 B면 재생시작점으로 이동되어 B면의 기록 독출을 시작한다.As the drive gear 204 is rotated by the operation of the drive motor 205 which continues after the reproduction of the A side of the disc 101 by the above operation, the pickup device 102 is automatically moved to the B side regeneration start point of the disc and the B side. Start reading the record.

A면과 B면의 재생이 모두 끝나면 구동모우터(205)의 역회전으로 픽업장치(102)는 다시 A면 재생시작점으로 복귀하게 되며, B면 재생중 A면 재생모드를 주었을 때도 상기한 동일한 동작을 완수한다.After the regeneration of the A side and the B side, the pickup device 102 returns to the A side regeneration start point by the reverse rotation of the driving motor 205, and the same as described above when the A side regeneration mode is given during the B side regeneration. Complete the action.

이와 같이 본 발명은 종래 것에 비하여 부품수를 수개 이상 줄이고 그 구등방법을 단순화하여 생산원가를 대폭줄이고 생산성을 높이어 가격경쟁력을 가진다.As described above, the present invention reduces the number of parts by more than a few, and simplifies the method of enlarging, thereby significantly reducing the production cost and increasing productivity, thereby having a price competitiveness.

또한 조립이 용이하므로 애프터서비스 시의 부품교체를 원활하게 한다.In addition, it is easy to assemble, which facilitates the replacement of parts during after-sales service.
