본 고안은 CD 플레이어의 CD 수납부 구동장치에 관한것으로서, 특히, 하나의 모터를 사용하여 CD 수납부를 효과적으로 개,폐할수 있게한 CD 플레이어의 CD 수납부 구동장치에 관한 것이다.The present invention relates to a CD storage unit driving apparatus of a CD player, and more particularly, to a CD storage unit driving apparatus of a CD player that can effectively open and close the CD storage unit using a single motor.

종래의 경우, CD(콤팩트 디스크)를 안착하는 트레이와 전체시스템을 안착하는 베이스, 그리고 CD를 클램핑하는 픽업시스템과 이를 상승,하강시키는 하나의 모터를 갖추면서, CD만을 개방시키기 위한 또 하나의 모터를 구비해야 했으므로, 이에 대한 각각의 연결부 및 메카니즘에 따른 부품수 증가와, 모터를 2개 사용함으로 인한 공간점유 등의 단점이 있었고, 조립및 제품단가 상승에도 많은 문제점이 발생하였다.Conventionally, another motor for opening only a CD, having a tray for seating a compact disc (CD), a base for seating the entire system, a pickup system for clamping the CD, and one motor for raising and lowering it. Since it had to be provided, there were disadvantages such as increase in the number of parts according to each connection part and mechanism and space occupancy due to the use of two motors, and many problems occurred in assembling and increasing the product cost.

따라서 본 고안은 상술한 바와같은 종래기술의 제반문제점을 감안하여 안출된 것으로서, 하나의 모터를 사용하여 기존의 동작을 수행케하면서 시스템의 공간점유를 최소화 하면서, 부품수 절감과 이에따른 제조단가 절감의 효과를 볼 수 있게한 CD 플레이어의 CD 수납부 구동장치를 제공하는데 그 목적이 있는것이다.Therefore, the present invention has been devised in view of the above-mentioned problems of the prior art, while minimizing the space occupancy of the system while performing a conventional operation using a single motor, reducing the number of parts and the subsequent manufacturing cost. It is an object of the present invention to provide a CD drive unit driving device of the CD player to be able to see the effect.

이하, 첨부된 도면을 참조하여 본 고안의 목적을 달성하기위한 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the technical configuration for achieving the object of the present invention.

도면 제1도에서 보는 바와같이 CD 디스크를 안착하는 트레이(10)는 전체시스템을 취부하는 베이스(20)에 조합되어 있고, CD 디스크를 재생하는 픽업유니트(30)와, CD 디스크를 취부하는 클램프유니트(47) 그리고 트레이(10)의 개,폐방시의 픽업유니트(30)를 상승,하강하는 모터(50)로 조합되어 있다.As shown in FIG. 1, a tray 10 for seating a CD disc is incorporated in a base 20 for mounting the entire system, and a pickup unit 30 for playing a CD disc, and a clamp for mounting a CD disc. The unit 47 and the tray 10 are combined with a motor 50 for raising and lowering the pickup unit 30 for opening and closing the tray 10.

또한, 시스템을 연결하는 메인기어(80)와 픽업유니트(30)를 상승,하강 시키는 캠기어(90)와 또한 이들의 연결기어(60)(70))로 구성되고, 픽업유니트(30)를 상승시켜 재생시에만 트레이(10)를 개,폐하는 상승기어(100)로 구성되어진다.In addition, the main gear 80 for connecting the system, the cam gear 90 for raising and lowering the pick-up unit 30, and also the connecting gears 60 and 70 thereof, and the pick-up unit 30 The lift gear 100 is configured to lift and open the tray 10 only at the time of regeneration.

한편, 픽업유니트(30) 상승시에는 상승기어(100)에 연결되어 구동되고 픽업 하강시에는 메인기어(80)에 연동하여 구동되는 연동기어(110)와, 캠기어(70)의 위치를 잡는 가이드캠(120)및 픽업유니트(30)의 상승, 하강을 감지하는 캠스위치(130)가 연결되며, 트레이(10)의 개,폐를 감지하는 열림,닫힘 감지스위치(150)(140)와 트레이(10)의 개,폐를 위한 래크기어(160)를 갖추어서 구성된것이다.On the other hand, when the pickup unit 30 rises and is connected to the driving gear 100 is driven, and when the pickup lowers the guide gear for driving the interlocking gear 110 and the cam gear 70 in conjunction with the main gear 80 Cam switch 130 for detecting the rising and falling of the cam 120 and the pick-up unit 30 is connected, the opening, closing detection switch 150, 140 and the tray for detecting the opening and closing of the tray 10 (10) is equipped with a rack gear 160 for opening and closing.

이상과 같이 구성되어진 본 고안의 작용 및 효과를 일실시예를 들어 구체적으로 설명한다.The operation and effects of the present invention configured as described above will be described in detail with reference to one embodiment.

도면 제5도에서 보는 바와같이 트레이(10)를 개방시키기 위해서는 모터(50)가 구동하면, 연결기어(60)(70)가 연동하여 메인 기어(80)가 구동한다.As shown in FIG. 5, when the motor 50 is driven to open the tray 10, the connecting gears 60 and 70 interlock to drive the main gear 80.

이때, 메인기어(80)의 캠기어 연결기어(60)가 유동되어 캠기어(90)가 연동되면, 가이드캠(120)이 고정홀을 따라 옴직이고 캠스위치(130)가 상승하여 온-오프 되고, 다시 온 될때까지 움직이게 된다.At this time, when the cam gear connecting gear 60 of the main gear 80 is flowed and the cam gear 90 is interlocked, the guide cam 120 is slit along the fixing hole and the cam switch 130 is raised to turn on-off. Until it is on again.

이어서, 계속 메인기어(80)가 회전하면 도면 제2도에서 보는 바와같이 연결기어(70)가 연동기어(110)에 A 방향으로 회전하고, 래크기어(160)에 의해 트레이(10)는 전진방향으로 나오면서 개방되는 것이다.Subsequently, when the main gear 80 continues to rotate, as shown in FIG. 2, the connecting gear 70 rotates in the A direction with respect to the interlocking gear 110, and the tray 10 is moved by the rack gear 160. It is opening in the forward direction.

이때, 메인기어(10)는 개방스위치 리브가 감지스위치(150)를 온 시키면서 트레이(10)의 개방이 완료되는 것이다.At this time, the main gear 10 is to open the tray 10 while the opening switch rib on the sensing switch 150 is completed.

한편, 트레이(10)를 원위치 시키고자 할시에는 즉, 폐방시에는 모터(50)의 회전에 의해 메인기어(80)가 B로 회전하면서, 연결기어(70)에 치합되어있는 연동기어(110)가 회전하여서 픽업하강이 닫히고 감지스위치(140)는 온 된다.Meanwhile, when the tray 10 is to be returned to its original position, that is, when the tray 10 is closed, the interlocking gear 110 engaged with the connecting gear 70 while the main gear 80 rotates to B by the rotation of the motor 50. Rotates the pickup lowering close and the detection switch 140 is turned on.

이때, 계속회전하면 캠기어(90)가 회전하고, 픽업유니트(30)가 상승되면 픽업에서 정지하게된다. 여기서 디스크가 재생되고 재생되는 디스크 외에 다른 디스크를 교환시에는 메인기어(80)의 기어상승 연결기어가 B로 회전하고, 기어상승에 연결된 연동기어(110)가 A방향으로 회전하여 트레이(10)가 개방된다. 트레이(10)가 개방되면 감지스위치(150)가 온 되어 정지하게된다.At this time, if the rotation continues, the cam gear 90 rotates, and when the pickup unit 30 is raised, the pickup stops. Here, when the disc is played back and the other discs are replaced, the gear rising connecting gear of the main gear 80 rotates to B, and the interlocking gear 110 connected to the gear rising rotates to the A direction so that the tray 10 may be replaced. Is opened. When the tray 10 is opened, the detection switch 150 is turned on to stop.

이상에서와 같이 본 고안은 하나의 모터를 이용하여 시스템의 공간을 줄일수 있고, 그 구조에 있어서도 단순구성을 이룰수 있으며 제조단가를 절감할수 있게된 고안인 것이다.As described above, the present invention can reduce the space of the system by using a single motor, achieve a simple configuration in the structure, and reduce the manufacturing cost.
