Description

디스크 플레이어의 디스크 척킹장치Disc Chucking Device for Disc Player

본 발명은 디스크 플레이어의 디스크 척킹장치에 관한 것으로서, 특히 디스크가 진입되기 위한 공간을 넓게 확보할 수 있도록 된 디스크 플레이어의 디스크 척킹장치에 관한 것이다.The present invention relates to a disc chucking apparatus of a disc player, and more particularly, to a disc chucking apparatus of a disc player which can secure a wide space for entering a disc.

일반적으로 CD플레이어나 CD-ROM과 같은 디스크 플레이어에는, 도 1 및 도 2에 도시된 바와 같이 턴테이블(20)에 안착된 디스크(40)를 견고하게 클램핑시킴으로써 회전시의 유동을 방지하기 위한 디스크 척킹장치가 마련되어 있다. 도면을 참조하면, 디스크(40)가 안착되는 턴테이블(20)에는 자력을 발생시키는 자석부재(21)가 부착되어 있고, 그 턴테이블(20) 상방에는 디스크(40)를 턴테이블(20)과의 사이에 클램핑시키기 위한 척킹부재(10)가 설치되어 있다. 이 척킹부재(10)에는 자성체(13)가 구비되어 있어서, 상기 턴테이블(20)에 접근하게 되면 상기 자석부재(21)와 자력결합되려는 인력을 받게 된다. 따라서 턴테이블(20)에 디스크(40)를 안착시킨 다음, 상기 척킹부재(10)를 턴테이블(20) 측으로 접근시키면, 도 1에 도시된 바와 같이, 상기 자석부재(21)와 자성체(13)가 인력을 받게 되며, 그에 따라 척킹부재(10)가 디스크(40)를 턴테이블(20) 측으로 압착시키게 되는 것이다. 도면의 참조부호 30은 상기 척킹부재(10)를 지지하는 지지아암을 나타내며, 이 지지아암(30)이 승강됨으로써 상기 척킹부재(10)가 턴테이블(20)에 대해 접근 및 이격된다. 그리고 상기 척킹부재(10)는 지지아암(30)의 결합공(31)에 유동가능하도록 헐겁게 결합되어 있어서, 디스크(40)를 클램핑한 후에 지지아암(30)에 간섭되지 않고 그 디스크(40)와 함께 회전할 수 있게 되어 있다. 따라서 상기 구성의 척킹장치에 있어서는, 지지아암(30)을 상승시켜서 상기 척킹부재(10)를 턴테이블(20)로부터 분리시켰을 때, 도 2에 도시된 바와 같이, 그 척킹부재(10)의 상단 걸림턱(11)이 지지아암(30)에 걸려서 매달려 있는 상태가 된다. 이와 같이 되면 상기 척킹부재(10)의 하단부(12)가 상기 턴테이블(20) 측으로 쳐져 있는 상태가 되기 때문에, 그 쳐진 높이만큼 턴테이블(20)과 사이의 공간(H)이 좁아지게 된다. 이 공간(H)은 디스크(40) 및 그 디스크(40)를 적재한 트레이(미도시)가 진입되기 위해 필요한 공간이기 때문에, 이 공간(H)이 좁아지게 되면 디스크(40)와 트레이 진입시에 간섭이 발생될 우려가 높아지게 된다.In general, in a disc player such as a CD player or a CD-ROM, as shown in FIGS. 1 and 2, the disk chucking to prevent flow during rotation by firmly clamping the disk 40 seated on the turntable 20. The device is provided. Referring to the drawings, a magnet member 21 for generating magnetic force is attached to the turntable 20 on which the disk 40 is seated, and the disk 40 is disposed between the turntable 20 and the disk 40 above the turntable 20. The chucking member 10 for clamping is provided. The chucking member 10 is provided with a magnetic body 13, and when approaching the turntable 20, the chucking member 10 receives an attraction force to be magnetically coupled to the magnet member 21. Therefore, when the disk 40 is seated on the turntable 20 and the chucking member 10 approaches the turntable 20 side, as shown in FIG. 1, the magnet member 21 and the magnetic body 13 are separated. Received the attraction, and thus the chucking member 10 is to squeeze the disk 40 to the turntable 20 side. Reference numeral 30 in the drawing represents a support arm for supporting the chucking member 10, and the support arm 30 is lifted so that the chucking member 10 approaches and is spaced apart from the turntable 20. The chucking member 10 is loosely coupled to the coupling hole 31 of the support arm 30 so that the chucking member 10 can flow, so that the disk 40 does not interfere with the support arm 30 after clamping the disk 40. It can be rotated with. Therefore, in the chucking device of the above configuration, when the support arm 30 is raised to separate the chucking member 10 from the turntable 20, as shown in FIG. 2, the upper end of the chucking member 10 is caught. The jaw 11 is suspended from the support arm 30. In this case, since the lower end portion 12 of the chucking member 10 is in a state of being struck toward the turntable 20, the space H between the turntable 20 is narrowed by the struck height. Since the space H is a space required for the disk 40 and a tray (not shown) on which the disk 40 is loaded, the space H becomes narrow when the disk H and the tray enters. There is a high possibility that interference will occur.

따라서 척킹부재(10)를 턴테이블(20)로부터 분리해낸 후에도 척킹부재(10)가 하방으로 쳐지지 않도록 된 디스크 척킹장치가 요구된다.Accordingly, there is a need for a disk chucking device in which the chucking member 10 is not struck downward even after the chucking member 10 is separated from the turntable 20.

본 발명은 상기의 점을 감안하여 창출된 것으로서, 척킹부재를 턴테이블로부터 분리해낸 후에도 하방으로 쳐지지 않게 지지하도록 구조 개선된 디스크 플레이어의 디스크 척킹장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object thereof is to provide a disc chucking device for a disc player that has been improved in structure so as not to be struck downward even after the chucking member is separated from the turntable.

이하 첨부된 도면을 참조하면서 본 발명에 따른 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 및 도 4는 본 발명에 따른 디스크 플레이어의 디스크 척킹장치를 나타낸다. 도면을 참조하면, 디스크(400)가 안착되는 턴테이블(200)의 상방에 그 디스크(400)를 턴테이블(200) 상에 압착시키기 위한 척킹부재(100)가 설치되어 있다. 이 척킹부재(100)의 하측에는 자력을 발생시키는 자석부재(110)가 설치되어 있어서, 척킹부재(100)를 턴테이블(200)에 접근시키게 되면 상기 자석부재(110)와 턴테이블(200)에 마련된 자성체(210) 사이에 인력이 작용하게 되고, 이 인력에 의해 디스크(400)가 도 3에 도시된 바와 같이 척킹부재(100)와 턴테이블(200) 사이에 클램핑된다. 그리고 이 척킹부재(100)는 지지아암(300)에 의해 지지되어서 이 지지아암(300)의 승강에 따라 상기 턴테이블(200)에 접근 또는 이격하게 된다. 여기서 상기 척킹부재(100)는 디스크(400)를 클램핑한 상태에서 상기 지지아암(300)에 간섭되지 않고 턴테이블(200)과 함께 회전할 수 있도록, 그 지지아암(300)의 결합공(310)에 헐겁게 지지되어 있다. 그런데 상기 척킹부재(100)를 지지하는 결합공(310) 테두리 부위는 자성체로 구성되어 있어서 상기 척킹부재(100)를 상기 턴테이블(200)로부터 이격시키면 상기 자석부재(110)와 상기 결합공(310)의 테두리 부위 사이에 인력이 발생되어, 도 4에 도시된 바와 같이 척킹부재(100)의 위치가 고정된다.3 and 4 show a disc chucking apparatus of a disc player according to the present invention. Referring to the drawings, the chucking member 100 for pressing the disk 400 on the turntable 200 is installed above the turntable 200 on which the disk 400 is seated. The lower side of the chucking member 100 is provided with a magnet member 110 for generating a magnetic force, and when the chucking member 100 approaches the turntable 200, the magnet member 110 and the turntable 200 are provided. The attraction force acts between the magnetic bodies 210, and by this attraction force the disk 400 is clamped between the chucking member 100 and the turntable 200 as shown in FIG. 3. The chucking member 100 is supported by the support arm 300 to approach or space the turntable 200 according to the lifting and lowering of the support arm 300. Here, the chucking member 100 can rotate with the turntable 200 without interfering with the support arm 300 while clamping the disk 400, the coupling hole 310 of the support arm 300. Loosely supported However, the edge portion of the coupling hole 310 supporting the chucking member 100 is formed of a magnetic material, so that the magnet member 110 and the coupling hole 310 are separated from the chucking member 100 by the turntable 200. The attraction force is generated between the edge portions of the), and as shown in FIG.

따라서 상기와 같이 척킹부재(100)의 위치가 자력에 의해 상승된 상태로 고정되기 때문에, 척킹부재(100) 하단(101)으로부터 턴테이블(200) 사이의 간격(H')이 종래보다 넓어지게 된다. 이와 같이 척킹부재(100)와 턴테이블(200) 사이의 간격(H')이 넓어지게 되면 디스크(400)와 그 디스크(400)를 이송시키는 트레이(미도시)의 진입공간이 넓게 확보되기 때문에, 디스크(400)를 디스크 플레이어 내부로 진입시키거나 또는 인출해낼 때 간섭이 일어나는 것을 방지할 수 있는 것이다.Therefore, since the position of the chucking member 100 is fixed in a raised state by magnetic force as described above, the distance H 'between the lower end 101 of the chucking member 100 and the turntable 200 becomes wider than before. . As such, when the distance H 'between the chucking member 100 and the turntable 200 becomes wider, an entry space of the disk 400 and a tray (not shown) for transporting the disk 400 is secured, Interference may be prevented when the disc 400 enters or leaves the disc player.

상술한 바와 같이 본 발명에 따른 디스크 플레이어의 디스크 척킹장치는, 척킹부재를 턴테이블로부터 이격시킨 상태에서 그 위치를 상향시켜서 고정시킬 수 있기 때문에, 디스크의 진입에 필요한 공간을 넓게 확보할 수 있으며 그에 따라 디스크 진입과 인출동작시에 간섭을 방지할 수 있다.As described above, the disc chucking apparatus of the disc player according to the present invention can secure the space necessary for the entry of the disc because the chucking member can be fixed by raising its position while being spaced apart from the turntable. Interference can be prevented during disk entry and withdrawal operations.

본 발명은 상기에 설명되고 도면에 예시된 것에 의해 한정되는 것은 아니며 다음에 기재되는 청구의 범위 내에서 더 많은 변형 및 변용예가 가능한 것임은 물론이다.It is to be understood that the invention is not limited to that described above and illustrated in the drawings and that many more modifications and variations are possible within the scope of the following claims.
