본 고안은 씨디-롬 드라이브(CD-ROM Drive)의 픽업(Pick-up) 록킹(Locking)장치에 관한 것으로 특히 그장치의 구성 품을 단순화시킴과 아울어 치형과 치형을 이용하여 픽업을 완전히 록킹시킴으로써 픽업보호에 적당하도록 한 씨디-롬 드라이브의 픽업 록킹장치에 관한 것이다.The present invention relates to a pick-up locking device of a CD-ROM drive, and in particular, to simplify the components of the device and to lock the pickup completely by using teeth and teeth. The present invention relates to a pick-up locking device of a CD-ROM drive, which is suitable for pick-up protection.
통상 엘디엠(LDS : linear DC Motor)을 사용하여 픽업을 구동시키는 씨디-롬 드라이브에는 그 드라이브의 로딩(Loading)및 언로딩(unloading)에 따라 선택적으로 픽업을 록킹 및 연록킹시켜 픽업의 충력을 방지하는 픽업 록킹장치가 내장되는 바, 이러한 픽업록킹장치는 제1도의 a, b에 도시한 바와같이, 일측단부에 누름핀(1a)의 하향돌출 구비된 로딩베이스(1)와, 그로딩이스(1)의 누름핀(1a)의 승강을 안내하는 통공(2a)이 구비된 픽업베이스(2)와, 상기 로딩베이스(1)의 누름핀(1a)이 삽입되는 경사 안내홈(4b)을 가지며 일측면에는 픽업홀더(3)의 록킹핀(3a)을 구속하는 수개의 반원형상의 홈(4a)이 구비된 스토퍼(4)로 구성되어 있으며, 상기 스토퍼(4)는 상기 픽업베이스(2)에 구비된 스토퍼 브래키트(5)에 스프링(6)으로 픽업(7)쪽을 향하도록 탄력지지되어 있다.A CD-ROM drive, which usually uses a linear DC motor (LDS) to drive the pickup, selectively locks and contacts the pickup according to the loading and unloading of the drive, thereby reducing the pickup's impulse. The pickup locking device is provided to prevent the bar, and as shown in a and b of FIG. 1, the pickup locking device includes a loading base 1 provided with a downward protrusion of the push pin 1a at one end thereof, and a grinding wheel. A pickup base 2 having a through hole 2a for guiding the lifting and lowering of the push pin 1a of (1), and an inclined guide groove 4b into which the push pin 1a of the loading base 1 is inserted; It consists of a stopper (4) having one side of the semicircular groove (4a) for restraining the locking pin (3a) of the pickup holder (3), the stopper (4) is the pickup base (2) It is elastically supported so that the stopper bracket 5 provided in the spring 6 may face the pickup 7.
도면에서 미설명부호 4c는 스프링 걸이부, 5a는 스프링걸이핀을 각각 보인 것이다.In the drawings, reference numeral 4c represents a spring hook portion, and 5a shows a spring hook pin.
이와같이 구성된 종래의 픽업 록킹장티는 로딩이 시작되면, 로딩베이스(1)가 하강함과 아울러 그의 누름핀(1a)이 스토퍼(4)의 경사안내홈(4b)에 삽입되면서 하강하게 된다. 이에 따라 스토퍼(4)는 도면에서 왼쪽으로 이동하면서 픽업홀더(3)의 록킹핀(3a)으로 부터 분리되어 픽업(7)의 구속이 해제되며 언로딩시 로딩베이스(1)가 상승되게 되면, 스토퍼(4)가 우측으로 이동하게 되어 픽업홀더(3)의 록킹핀(3a)을 구속 함으로써 픽업(7)을 고정하게 되는 것이다.The conventional pick-up locking tee configured as described above is lowered when the loading base 1 is lowered and the push pin 1a is inserted into the inclined guide groove 4b of the stopper 4 when the loading base 1 is lowered. Accordingly, when the stopper 4 moves to the left in the drawing and is separated from the locking pin 3a of the pickup holder 3, the restraint of the pickup 7 is released, and the loading base 1 is raised during unloading. The stopper 4 is moved to the right to fix the pickup 7 by restraining the locking pin 3a of the pickup holder 3.
그러나 종래의 픽업록킹장치는 구성부품이 많아 조립과정이 복잡하며 록킹시 픽업홀더(3)의 록킹핀(3a)이 스토퍼(4)의 반원형상의 홈(4a) 돌출부에 위치할 수 있고 이와같이 위치하면, 상기 록킹핀(3a)을 반원형상의 홈(4a)에 완전히 들어가게 하기 위하여 불필요한 이동을 해야 하며, 또한 스프링(6)의 경시변화로 인한 안정적인 효과를 기대할 수 없을 뿐만 아니라 반원형상의 홈(4a)으로 되어 있는 록킹홈에 록킹핀(3a)이 접촉되는 구조이므로 완전한 록킹이 어렵고, 이로인해 픽업의 유동이 발생하여 픽업에 충격을 주는 결함이 있었다.However, the conventional pickup locking device has a large number of components, which assembles a complicated assembly process. When locking, the locking pin 3a of the pickup holder 3 may be located at the protrusion of the semicircular groove 4a of the stopper 4. In order to completely enter the locking pin 3a into the semicircular groove 4a, an unnecessary movement must be made, and a stable effect due to the time-dependent change of the spring 6 can not be expected as well as the semicircular groove 4a. Since the locking pin (3a) is in contact with the locking groove is a complete locking is difficult, due to this there is a defect that the pick-up flow occurs to impact the pickup.
따라서, 본 고안은 상기한 바와같은 종래 픽업록킹장치의 결함을 해소하기 위하여 안출한 것으로 스프링을 제거함과 아울러, 스토퍼와 픽업홀더부에 각각 치형을 형성하여 이 치형을 서로 맞물리게 함으로써 픽업을 완전히 록킹시킬 수 있도록 한 것인바, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention is designed to solve the defects of the conventional pick-up locking device as described above, and removes the spring, and forms the teeth on the stopper and the pick-up holder, respectively, to engage the teeth with each other so as to completely lock the pickup. The bar will be described in detail with reference to the accompanying drawings.
즉, 본 고안에 의한 픽업록킹장치는 제2도의 a, b에 도시한 바와같이 로딩베잇(1)의 승강작동으로 픽업(7)을 록킹 및 언록킹시키는 픽업록킹장치에 있어서, 상기 로딩베이스(1)와 일체로 스토퍼 브래키트(11)를 설치함과 함께 그 스토퍼 브래키트(11)에 치형(12a)이 일측면에 구비된 스토퍼(12)를 고정하는 한편, 상기 픽업(7)이 탑재된 픽업홀더(13)의 록킹부(13a)단부에 상기 스토퍼(12)의 치형(12a)과 맞물리는 치형(13b)을 형성한 것을 특징으로 하고 있으며 상기 스토퍼(12) 및 픽업홀더(13)의 록킹부(13a)에 형성된 치형(12a)(13b)이 서로 결합 및 이탈이 용이하도록 구성되어 있다.That is, the pickup locking device according to the present invention is a pickup locking device for locking and unlocking the pickup 7 by lifting and lowering of the loading beet 1 as shown in a and b of FIG. 1) the stopper bracket 11 is provided integrally with the stopper bracket 11, and the stopper 12 having the teeth 12a on one side thereof is fixed to the stopper bracket 11, and the pickup 7 is mounted thereon. The stopper 12 and the pick-up holder 13 are characterized in that a tooth 13b is formed at the end of the locking portion 13a of the pick-up holder 13, which meshes with the teeth 12a of the stopper 12. Teeth 12a and 13b formed on the locking portion 13a of the structure are configured to facilitate engagement and disengagement with each other.
이와같이 된 본 고안에 의한 픽업록킹장치의 작용을 살펴보면, 먼저 언로딩시에는 스토퍼(12)의 치형(12a)과 픽업홀더(13)의 록킹부치형(13b)이 서로 맞물리게 되어 픽업(7)은 고정되며 로딩베이스(1)가 로딩을 시작하면, 그 로딩베이스(1)가 하강하게 되고 이에 따라 로딩베이스(1)와 일체로 된 스토퍼(12)가 하강하게 되어 그 스토퍼(12)의 치형(12a)이 픽업홀더(13)의 록킹부 치형(13b)으로 부터 분리되어 픽업의 구속을 해제하게 된다. 또한 동작의 완료나 스톱모드에 의해 로딩베이스(1)가 다시 상승하게 되면, 스토퍼(12)가 상승하게 되고 이에따라 그 스토퍼(12)의 치형(12a)과, 픽업홀더(13)의 록킹부 치형(13b)이 서로 맞물림으로써 픽업(7)을 구속하게 되는 것이다.Looking at the action of the pickup locking device according to the present invention as described above, first, when unloading, the teeth 12a of the stopper 12 and the locking butt type 13b of the pickup holder 13 are engaged with each other, so that the pickup 7 is When the loading base 1 starts to be loaded and the loading base 1 starts loading, the loading base 1 is lowered and thus the stopper 12 integrated with the loading base 1 is lowered and the teeth of the stopper 12 are lowered. 12a) is separated from the locking portion tooth 13b of the pickup holder 13 to release the restraint of the pickup. In addition, when the loading base 1 is raised again by the completion of the operation or the stop mode, the stopper 12 is raised, and accordingly, the teeth 12a of the stopper 12 and the locking part teeth of the pickup holder 13 are raised. By engaging 13b with each other, the pickup 7 is constrained.
이상에서 설명한 바와같이 본 고안에 의한 픽업 록킹장치는 스프링등을 제거하여 구성부품을 단순화 시킴으로써 조립을 용이하게 함과 아울러 조립시간을 단축하였으며 또한, 스토퍼에 형성된 치형과 픽업홀더의 록킹부치형을 이용하여 픽업을 록킹시킴으로 픽업을 완전히 록킹시킬 수 있고 이에 따라 픽업 유동으로 인한 충격으로 부터 픽업을 보호할 수 있는 효과가 있다.As described above, the pick-up locking device according to the present invention simplifies the assembly by removing the spring and the like, thereby facilitating assembly and shortening the assembly time. By locking the pickup, it is possible to completely lock the pickup, thereby protecting the pickup from the impact of the pickup flow.
