본 고안은 디스크를 수직으로 장착하는 콤팩트 디스크 플레이어(CDP)에 있어서, 판스프링의 탄성을 이용하여 디스크를 턴테이블에 밀착 고정 시켜주도록한 디스크 고정장치에 대한 것이다.The present invention is a compact disk player (CDP) for mounting the disk vertically, the disk fixing device for fixing the disk close to the turntable using the elasticity of the leaf spring.

종래에는 제 2b 도에서 보는 바와 같이 디스크(3)을 장착하면 도어의 호울더(2)에 결합된 브라켓트(1)에 착설한 마그네트(5)의 자력으로 디스크(3)를 턴테이블(4)에 밀착 고정시켜 주도록 하였는데, 이러한 장치는 회전시 디스크(3)가 유동되지 않게 하여 주기 위해서는 강한 자력이 필요하게 되므로 상대적으로 도어를 열때는 마그네트(5)의 자력을 분리시켜 줄 수 있는 힘이 가해져야 되기 때문에 결국 도어를 자동으로 열어주기위해 착설하는 비틀림스프링의 반발력이 상기 마그네트의 자력 보다 큰 것을 사용해야 되며, 이에 따라 도어를 닫으면 비틀림스프링의 반발력이 도어에 항상 작용하게 되므로 도어가 변형되는 폐단이 있었음은 물론 열릴때 서서히 부드럽게 열리질 않게 되었고, 또 마그네트를 고정하기 위한 스크류가 필요하며 자체의 가격이 높아 원가도 상승되는등 많은 문제점들이 있었다.Conventionally, as shown in FIG. 2B, when the disk 3 is mounted, the disk 3 is attached to the turntable 4 by the magnetic force of the magnet 5 mounted on the bracket 1 coupled to the holder 2 of the door. In order to prevent the disk 3 from flowing during rotation, such a device requires a strong magnetic force. Therefore, when the door is opened, a force that can separate the magnetic force of the magnet 5 must be applied. As a result, the repulsive force of the torsion spring installed in order to open the door automatically must be larger than the magnetic force of the magnet. Therefore, when the door is closed, the repulsive force of the torsion spring always acts on the door, so the door was deformed. Of course, when it is opened, it does not open slowly and smoothly, and it requires a screw to fix the magnet and its price is high. There were many problems, including rising costs.

본 고안은 이러한 점들을 해결하기 위해 고안한 것으로 도어에 착설하는 호울더에 디스크의 고정판을 판스프링으로 탄발되게 결합시켜 이 스프링의 탄성을 이용 고정판으로 디스크를 턴테이블에 밀착 고정시켜 주도록하므로 도어를 열때 큰힘이 필요없게 됨은 물론 도어의 변형등과 같은 폐단도 제거되게한 것이다.The present invention is designed to solve these problems. When the door is opened, the fixed plate of the disk is firmly coupled to the holder installed on the door by the leaf spring, and the spring is fixed to the turntable by the fixed plate. Not only does it require a lot of force, but it also removes closed ends such as door deformation.

이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도어(1) 내면에 착설하는 호울더(2)에는 결합공(21)을 뚫고 이 결합공의 상하주면에는형상의 걸이편(22)을 일체로 연설하였으며, 디스크(3)를 턴테이블(4)에 밀착 고정시켜 주기 위한 고정판(5)의 외면중앙에는 핀홈(51)을 요입형성하고 내면 중양에는 축핀(52)을 돌출하며 결합부(53) 주면에는 수개의 걸림편(54)들을 연설하였고, 상기 고정판을 호울더에 결합시켜 디스크를 결합시켜 디스크를 밀착, 고정토록하여 주는 판스프링(6)의 중앙에는 축지지부(61)를 형성하고 양측편(62)들의 각 중간부분에는 절곡부(63)를 형성하여 자체탄성을 갖도록 하고 양단에는 걸림홈(64)을 턴테이블(4)의 중앙에는 지지핀(41)을 돌출시켰다.The holder 2 installed on the inner surface of the door 1 drills a coupling hole 21, and the upper and lower circumferential surfaces of the coupling hole The hanger 22 of the shape was integrally addressed, and the pin groove 51 was recessed in the center of the outer surface of the fixing plate 5 for fixing the disk 3 to the turntable 4 in close contact, and the shaft pin 52 in the inner center of the shaft. ) Protrudes a plurality of engaging pieces (54) on the main surface of the coupling portion 53, in the center of the leaf spring (6) for coupling the disk to the holder by coupling the fixing plate to the holder. The shaft supporting portion 61 is formed, and the bent portion 63 is formed at each middle portion of both side pieces 62 to have self-elasticity, and the locking groove 64 is formed at both ends of the support pin 41 at the center of the turntable 4. ) Is extruded.

이와 같이 되는 본 고안은 고정판(5)의 결합부(53)를 호울더(2)의 결합공(21)에 끼워 이 결합공 내주면에 걸림편(54)들이 걸려서 이탈되지 않게 한 다음 판스프링(6)을 그 양단에 형성한 걸림홈(64)들이 호울더 (2)의 걸이편(22)들에 걸어지게 결착하면 상기 고정판은 판스프링에 의해 탄발되어 제 2a 도에서 보는 바와 같이 다음 도어(1)를 닫으면 장착된 디스크(3)를 턴테이블(4)에 밀착, 고정시켜 주게되며 이때 이 턴테이블에 돌출시킨 지지핀(41)은 고정판(5)의 핀홈(51)에, 또 이 고정판의 축핀(52)은 판스프링(6)의 축지지부(61)에 각각 결합되어 서로 지지하여 주게 되므로 동작시 디스크(3)가 유동됨이 없이 안정되게 회전한다.The present invention is thus fitted to the engaging portion 53 of the fixing plate (5) in the coupling hole 21 of the holder (2) so that the engaging pieces (54) on the inner circumferential surface of the coupling hole is caught off and then the leaf spring ( When the engaging grooves 64 formed at both ends thereof are fastened to the hook pieces 22 of the holder 2, the fixing plate is shot by the leaf spring, and as shown in FIG. 1) Close and fix the mounted disk 3 to the turntable 4, and at this time, the support pin 41 protruding from the turntable is fixed to the pin groove 51 of the fixing plate 5 and the shaft pin of the fixing plate. 52 are respectively coupled to the axial support 61 of the leaf spring 6 to support each other, so that the disk 3 rotates stably without movement.

이와 같이 본 고안은 판스프링(6)의 탄성을 이용하여 고정판(5)이 디스크(3)를 턴테이블(4)에 밀착, 고정시켜주도록 하였기 때문에 도어(1)를 자동으로 열어주는 스프링의 반발력은 강한 것을 사용할 필요가 없게 되며, 이에 따라 도어의 변형이나 급격한 열림동작이 해소됨은 물론 구조가 간단하고 부품 감소와 원가의 절감효과도 얻을 수 있게 되는 것이다.As such, the present invention uses the elasticity of the leaf spring 6 to fix the disk 3 to the turntable 4 in close contact with the turntable 4 so that the repulsive force of the spring that automatically opens the door 1 is There is no need to use a strong one, thereby eliminating the deformation of the door and the sudden opening operation, as well as the simple structure and the reduction of parts and cost can be obtained.
