본 고안은 콤팩트 디스크 플레이어의 픽업고정장치에 관한 것으로, 특히, CD-ROM의 이동이나 운반시 픽업을 고정하여 충격을 방지하기 위한 픽업고정장치에 관한 것이다.The present invention relates to a pickup fixing device for a compact disc player, and more particularly, to a pickup fixing device for preventing a shock by fixing a pickup when moving or carrying a CD-ROM.
콤팩트 디스크 플레이어(이하, CDP로 약칭함)에 있어서 콤팩트 디스크에 기록된 정보를 읽기 위해 광학픽업이 사용되며, 이 픽업의 위치는 리니어 모터에 의해 제어된다. 그러나, 콤팩트 디스크 플레이어, 예컨대 CD-ROM에 있어서, 이 CD-ROM의 운반이나 이동시에는 전원을 차단하여야 하므로, 리니어 모터의 제어력이 상실되어, 픽업은 그의 자중으로 인해 픽업의 위치를 고정하는 샤프트에 대한 미끄러짐이 발생되게 된다.In a compact disc player (hereinafter abbreviated as CDP), optical pickup is used to read information recorded on a compact disc, and the position of this pickup is controlled by a linear motor. However, in a compact disc player such as a CD-ROM, the power supply must be shut off when carrying or moving the CD-ROM, and thus the control power of the linear motor is lost, and the pickup is caused by the weight of the shaft to fix the position of the pickup. Slip is generated.
이를 방지하기 위해 종래는 제1도에 도시한 바와 같이, 픽업(1)의 일측 가장자리에 돌출부(1a)를 형성하고, 이에 래치(4)가 걸리도록 하여 픽업(1)을 고정하는 방법이 사용되고 있다. 이때, 픽업(1)의 사용시는 스프링(4a)을 통해 래치(4)를 뒤로 젖혀 픽업(1)을 해제시키며, 이를 위해 도시되지 않은 디스크 로딩 시스템의 로딩 모터의 구동력을 이용한다.In order to prevent this, conventionally, as shown in FIG. 1, a method of forming a protrusion 1a on one side edge of the pickup 1 and locking the latch 1 by the latch 4 is used. have. At this time, when the pickup 1 is used, the latch 4 is flipped back through the spring 4a to release the pickup 1, and the driving force of the loading motor of the disc loading system is not used for this purpose.
이때, CDP의 픽업(1)은 2개의 샤프트(2,3)에 의해 세팅되는데, 제1샤프트(2)에 의해 축의 위치정도가 결정되고, 제2샤프트는 2샤프트의 위치공차를 흡수하기 위한 슬라이드 베어링과 결합되어 있다.At this time, the pickup 1 of the CDP is set by two shafts 2 and 3, and the position of the shaft is determined by the first shaft 2, and the second shaft is used to absorb the position tolerance of the two shafts. Combined with the slide bearing.
그러나, 이러한 종래 기술은 제2도에 도시한 바와 같이 래치(4)가 픽업(1)의 가장자리에 걸리므로 픽업(1)의 무게 중심과 상당한 거리에 있게 되어 샤프트에 모멘트가 걸리는 문제가 있으며, 또한 픽업(1)에 돌출부(1a)를 형성하여야 하므로 픽업(1)의 크기가 커짐은 물론 중량이 무거워지는 결점이 있다.However, this prior art has a problem that the latch 4 is caught on the edge of the pickup 1, as shown in FIG. In addition, since the protrusions 1a must be formed in the pickup 1, the size of the pickup 1 is large, as well as a weight.
따라서, 본 고안은 상기와 같은 종래 기술의 단점을 제거하기 위한 것으로, 본 고안의 목적은 광학픽업장치를 사용하지 않을 때, 이를 확실히 고정시킴으로써 CDP의 운반이나 이동시 픽업장치에 무리가 가지 않도록 한 CDP의 픽업고정장치를 제공하는 것이다.Therefore, the present invention is intended to eliminate the disadvantages of the prior art as described above, and the object of the present invention is to securely fix the CDP when not using the optical pick-up device, so that the CDP is not overly picked up when the CDP is transported or moved. It is to provide a pickup fixing device of.
상기 목적을 달성하기 위한 본 고안의 CDP용 픽업고정장치는, 픽업을 활주시켜 위치 설정하기 위한 제1 및 제2샤프트와, 스토퍼수단으로 사용되는 상기 제2샤프트의 하단부에 인장스프링을 통해 연결되어 픽업을 이동시키기 위한 슬라이드수단과, 상기 슬라이드수단을 좌우 이동시키기 위해 상기 슬라이드수단과 핀수단을 통해 연동되어 있는 가이드수단을 구비하여 이루어지며, 상기 제2샤프트는 픽업을 고정시키기 위한 요부가 그 하단부에 형성된 것을 특징으로 한다.The pickup fixing device for CDP of the present invention for achieving the above object is connected to the lower end of the second shaft used as a stopper means and the first and second shafts for sliding and positioning the pickup is connected through a tension spring And slide means for moving the pickup, and guide means interlocked through the slide means and the pin means for moving the slide means to the left and right, and the second shaft has a recess for fixing the pickup. Characterized in that formed.
이하, 본 고안의 바람직한 1실시예에 따른 CDP의 픽업고정장치를 첨부 도면에 따라 상세히 설명한다.Hereinafter, a pickup fixing device for a CDP according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

To form the recess so that the recess is brought into close contact with the slide bearing wall of the pickup when the CDP is not used.
제4도는 본 고안에 이한 CDP의 픽업고정장치의 상세도로서, 이하, 본 고안의 구성 및 동작을 제3도 및 제4도에 따라 상세히 설명한다.4 is a detailed view of the pickup fixing device of the CDP according to the present invention. Hereinafter, the configuration and operation of the present invention will be described in detail with reference to FIGS. 3 and 4.
본 고안의 CDP용 픽업고정장치는, 제3도에 도시된 바와 같이 픽업을 활주시켜 위치 설정하기 위한 제1 및 제2샤프트(2),(3′)와, 상기 제2샤프트(3′)의 하단부에 인장스프링(9)을 통해 연결되어 픽업(1)을 이동시키기 위한 슬라이드부재(8)와, 상기 슬라이드부재(8)을 좌우 이동시키기 위해 상기 슬라이드부재(8)에 핀(10)을 통해 연동되어 있는 가이드부재(7)를 구비하여 이루어지며, 상기 제2샤프트(3′)에는 픽업을 고정시키기 위한 요부(3a)가 그 하단부에 형성되어 있다.CDP pickup fixing device of the present invention, the first and second shafts (2), (3 ') and the second shaft (3') for sliding and positioning the pickup as shown in FIG. The slide member 8 is connected to the lower end of the slide spring 9 to move the pickup 1, and the pin 10 is attached to the slide member 8 to move the slide member 8 side to side. And a guide member 7 which is interlocked with each other, and a recess 3a for fixing the pickup is formed at a lower end of the second shaft 3 '.
본 고안에 의한 CDP의 픽업지지장치는 특히 제4도에 상세히 도시된 바와 같이, 공지의 제1샤프트(2′)는 그대로 두고, 제2샤프트(3′)의 대략 중간부에서 하측으로 요부(3a)를 형성하여, 픽업(1)의 사용시는 점선의 위치로 상승하고, 비사용시는 실선위치로 하강하여 상기 요부(3a)가 픽업(1)의 슬라이딩 베어링벽에 밀착되어 디스크가 지지되도록 한다.The pickup support apparatus of the CDP according to the present invention is particularly shown in detail in FIG. 4, with the well-known first shaft 2 'as it is, and the recessed portion (approximately from the middle of the second shaft 3' to the lower side ( 3a) is raised to the position of the dotted line when the pickup 1 is in use, and lowered to the solid line position when the pickup 1 is in use, so that the recessed portion 3a is brought into close contact with the sliding bearing wall of the pickup 1 to support the disk. .
즉, 제3도 및 제4도에 도시된 바와 같이, CDP를 사용할 때는 가이드(7)가 내려와서 슬라이드(8)를 좌측으로 밀게 되는데, 이때 슬라이드(8)와 제2샤프트(3′)에 연결된 인장스프링(9)이 제2샤프트(3′)를 왼쪽으로 밀어 픽업(1)이 샤프트(3′)를 통해 활주할 수 있게 된다. 이 동작을 좀 더 상세히 설명하면, CDP 사용시, 도시되지 않은 별도의 디스크 로딩 시스템에 의해 가이드(7)가 하강하여, 핀(10)을 통해 연동되는 슬라이드(8)를 좌측으로 밀게 되는데, 이때, 슬라이드(8)는 핀(11,12)이 그 안으로 삽입되는 장공(8a)에 의해 좌측으로 이동되고, 이와 동시에 인장스프링(9)에 의해 제2샤프트(3′)가 좌측으로 이동되고, 이와 동시에 인장스프링(9)에 의해 제2샤프트(3′)가 좌측으로 이동하게 된다. 이때, 제2샤프트(3′)에서 형성된 요부(3a)가 픽업(1)의 슬라이딩 벽으로부터 벗어나게 되어 제2샤프트(3′)는 픽업(1)의 활주를 방해하지 않게 된다.That is, as shown in FIGS. 3 and 4, when the CDP is used, the guide 7 descends and pushes the slide 8 to the left, whereby the slide 8 and the second shaft 3 ' The connected tension spring 9 pushes the second shaft 3 'to the left so that the pickup 1 can slide through the shaft 3'. To describe this operation in more detail, when using the CDP, the guide 7 is lowered by a separate disk loading system (not shown) to push the slide 8 interlocked through the pin 10 to the left. The slide 8 is moved to the left by the long holes 8a into which the pins 11 and 12 are inserted, and at the same time the second shaft 3 'is moved to the left by the tension spring 9. At the same time, the second shaft 3 'is moved to the left by the tension spring 9. At this time, the recess 3a formed in the second shaft 3 'is deviated from the sliding wall of the pickup 1 so that the second shaft 3' does not interfere with the slide of the pickup 1.
다음, CDP의 사용이 종료된 후, 디스크를 이젝트하면, 디스크 로딩 시스템에 연동되는 가이드(7)가 상승함과 동시에 슬라이드(8)는 우측으로 이동하며, 이에 따라 제2샤프트(3′)가 핀(13)을 중심으로 하여 우측으로 이동하여 그의 평면부(3b)가 슬라이딩 베어링벽에 밀착되게 된다. 이때 상기 슬라이드(8)의 우측 이송은 핀(11) 및 (12)를 통해 장공(7a) 및 (8a)내에서 수행된다.Next, after the use of the CDP is finished, the disc is ejected, and the slide 8 moves to the right at the same time as the guide 7 interlocking with the disc loading system is raised, whereby the second shaft 3 ' The planar portion 3b thereof is brought into close contact with the sliding bearing wall by moving to the right around the pin 13. At this time, the right feed of the slide 8 is performed in the long holes 7a and 8a through the pins 11 and 12.
다음, CDP를 운반이나 이동시키기 위하여, 가이드(7)가 상승되면 상기 로딩시와 역순으로 슬라이드(8)가 우측으로 이동하고, 픽업(1)이 그의 자중으로 하강되어 상기 제2샤프트(3′)의 요부(3a)에 다다르면 슬라이딩 베어링벽이 상기 요부(1)에 지지되어, 픽업이 고정되게 된다.Then, in order to transport or move the CDP, when the guide 7 is raised, the slide 8 moves to the right in the reverse order of the loading, and the pickup 1 is lowered to its own weight so that the second shaft 3 ' The sliding bearing wall is supported by the recess 1 when the recess 3a is reached, so that the pickup is fixed.
따라서, 상기와 같이 구성된 본 고안에 의하면, 제2샤프트(3′)를 픽업지지용의 스토퍼로 구성함으로써 상기 스토퍼 수단이 픽업의 중심과 가까이 위치하게 되어 샤프트에 모멘트가 걸리지 않게 됨과 동시에, 픽업에 돌출부가 필요없게 되어 경량화되고, 래치부가 제거됨으로써, 제품의 특성을 향상시킴은 물론 제조코스트가 절감된다.Therefore, according to the present invention configured as described above, by configuring the second shaft 3 'as a stopper for pick-up support, the stopper means is positioned close to the center of the pick-up so that the moment is not applied to the shaft, By eliminating the need for a protrusion, the weight is reduced, and the latch part is removed, thereby improving product characteristics and reducing manufacturing cost.
