컴팩트디스크 플레이어의 클램핑장치{CLAMPING APPARATUS OF CD PLAYER}Clamping device for compact disc player {CLAMPING APPARATUS OF CD PLAYER}

본 발명은 컴팩트디스크 플레이어의 클램핑장치에 관한 것으로서, 보다 상세히는 컴팩트 디스크 플레이어에서 디스크가 삽입되어 재생될 때, 턴테이블 위에 디스크가 안착되고 그 위에 클램퍼가 눌려진 상태에서 스핀들모터에 의해서 회전될 때, 디스크를 눌려주는 역할을 하는 컴팩트디스크 플레이어의 클램핑장치에 관한 것이다.The present invention relates to a clamping device of a compact disc player, and more particularly, when a disc is inserted and played in a compact disc player, when the disc is seated on the turntable and rotated by the spindle motor while the clamper is pressed on it. The present invention relates to a clamping device of a compact disc player that serves to press.

종래의 경우를 도 1을 참조하여 설명하기로 한다.A conventional case will be described with reference to FIG. 1.

이하, 본 발명의 실시예를 첨부한 도면을 참조하여 설명하기로 한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 2를 참조하면, 본 발명에 따른 컴팩트디스크 플레이어의 클램핑장치가 도시되어 있다. 본 발명에 따른 컴팩트디스크 플레이어는 모터샤프트(24)가 장착된 스핀들모터(23)가 구비되고, 상기 모터샤프트(24) 상부에는 턴테이블(27)이 장착된다.2, there is shown a clamping device of a compact disc player according to the present invention. The compact disc player according to the present invention includes a spindle motor 23 on which a motor shaft 24 is mounted, and a turntable 27 is mounted on the motor shaft 24.

상기 턴테이블(27)의 내부에는 스프링(32)이 장착되고, 측면에는 회전축(30)에 의해서 회전가능한 레버(29)가 구비된다.A spring 32 is mounted inside the turntable 27, and a lever 29 rotatable by the rotating shaft 30 is provided on a side of the turntable 27.

상기 레버(29) 하부에는 링와셔(34)가 모터샤프트(24)에 장착되어, 턴테이블(27) 회전시 마찰력을 감소시킨다.A ring washer 34 is mounted below the lever 29 to the motor shaft 24 to reduce friction when the turntable 27 rotates.

상기 링와셔(34) 하부에는 연결블럭(36)이 모터샤프트(24)에 장착되고, 상기 연결블럭(36)은 스핀들모터(23)상에서 스크류(51)로 고정된 받침대(49)상에서 왕복운동하는 가압블럭(39)과 맞닿게되고, 상기 가압블럭(39)은 링크(41)의 일단에 연결되고, 상기 링크(41)의 타단은 솔레노이드(45)에 연결된다.A connection block 36 is mounted to the motor shaft 24 below the ring washer 34, and the connection block 36 reciprocates on a pedestal 49 fixed by a screw 51 on the spindle motor 23. The pressure block 39 is in contact with the pressure block 39, and the pressure block 39 is connected to one end of the link 41, and the other end of the link 41 is connected to the solenoid 45.

상기와 같은 구성에 의해서 본 발명에 따른 컴팩트디스크 플레이어의 클램핑장치는 다음과 같이 작동된다.By the above configuration, the clamping device of the compact disc player according to the present invention operates as follows.

도3과 같이 클램핑 해제상태에서 디스크(25)가 삽입 완료되면, 솔레노이드(45)가 작동하여 링크(41)를 당기게되고, 그러면, 가압블럭(39)이 도 2에서 좌측으로 이동되고, 이에따라 가압블럭(39) 및 링와셔(34)가 모터샤프트(24)를 따라 상승하게되고, 이것에 의해서 레버(29)가 회전축(30)을 중심으로 시계방향으로 회전되어 디스크(25)가 레버(29)의 단부에 걸림되어 클램핑되는 것이다.When the disk 25 is inserted in the clamping release state as shown in FIG. 3, the solenoid 45 is operated to pull the link 41, and then the pressure block 39 is moved to the left side in FIG. The block 39 and the ring washer 34 are raised along the motor shaft 24, whereby the lever 29 is rotated clockwise about the rotational shaft 30 so that the disk 25 is lever 29. It is caught and clamped at the end.

반대로, 도 2와 같이 클램핑 상태에서 디스크(25) 인출 신호가 솔레노이드(45)에 가해지면, 솔레노이드(45)가 작동하여 링크(41)를 밀게되고, 그러면, 가압블럭(39)이 도 2에서 우측으로 이동되고, 이에따라 가압블럭(39) 및 링와셔(34)가 모터샤프트(24)를 따라 하강하게되고, 이것에 의해서 레버(29)가 회전축(30)을 중심으로 시계반대방향으로 회전되어 디스크(25)가 레버(29)의 단부에 걸림림 해제되어 디스크가 상승되는 것이다.On the contrary, when the disk 25 withdrawal signal is applied to the solenoid 45 in the clamping state as shown in FIG. 2, the solenoid 45 operates to push the link 41, and then the pressure block 39 is pressed in FIG. 2. And the pressure block 39 and the ring washer 34 are lowered along the motor shaft 24, whereby the lever 29 is rotated counterclockwise about the rotation shaft 30. The disk 25 is released from the end of the lever 29 to lift the disk.

상술한 바와같이, 본 발명에 따른 컴팩트디스크 플레이어의 클램핑장치는 턴테이블 하부에서 솔레노이드에 의한 작동으로 디스크 클램핑 작동이 이루어지므로 턴테이블 상부의 공간을 차지하지 않게 되고, 클램핑 메카니즘이 단순화되어 부품을 절약할 수 있는 효과가 있다.As described above, the clamping device of the compact disc player according to the present invention does not occupy the space above the turntable because the disk clamping operation is performed by the solenoid operation at the lower part of the turntable, and the clamping mechanism is simplified to save parts. It has an effect.

이상에서 설명한 것은 본 발명에 따른 컴팩트디스크 플레이어의 클램핑장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자가라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is only one embodiment for implementing the clamping apparatus of the compact disc player according to the present invention, and the present invention is not limited to the above-described embodiment, and the gist of the present invention as claimed in the following claims. Various changes can be made by those skilled in the art without departing from the scope of the present invention.
