Problems solved by technology

[0007] However, the core plate with increased mass is not only not suitable for high-speed rotation, but also increases the cost of the product, and hinders the miniaturization of the product
In addition, when the rigidity of the buffer is increased, it is not possible to effectively reduce external impact or vibration.

Embodiment Construction

[0035] Such as figure 2 As shown, the disc player according to the preferred embodiment of the present invention includes: a core base 50, a core plate 70 elastically connected to the core base 50, a buffer inserted between the core base 50 and the core plate 70 Part 60, the rotating shaft motor 100 installed on the core board 70, the turntable 200, the optical head 75, the clamper 300 installed facing the turntable 200 for clamping the disk 1 placed on the turntable 200 and used to prevent the The self-compensating dynamic balancer 400 for the eccentric rotation of the rotating shaft 130 of the rotating shaft motor 100 caused by the eccentric center of gravity of the disc 1 .

[0036] The movement board 70 receives the impact from the outside which is slowed down by the buffer member 60 through the movement base 50. Therefore, in order to slow down the external vibration transmitted from the movement base 50, the buffer member 60 is preferably made of a material with low rig...

Abstract

The present invention discloses a disk player having a self-compensating dynamic balancer capable of limiting internal vibrations caused by the eccentricity of the disk's center of gravity. The self-compensating dynamic balancer is integrally formed with the rotating components within the disc player, ie the turntable, clamper and / or rotor of the spindle motor. The self-compensating dynamic balancer includes at least one raceway which is integrally formed with the rotating part and rotates around a rotating shaft, a floating member which is installed in the raceway and can swim, and a cover covering the opening of the raceway.

Description

technical field [0001] The present invention relates to a disc player. Background technique [0002] Generally, a disc player records and / or plays back information on and / or from recording media such as compact discs (CDs), CD-ROMs and digital versatile discs (DVDs). Due to their sensitivity, disc players are required to protect the disc and optical head from external shocks and internal vibrations. [0003] Such as figure 1 As shown, a typical disk player includes a core base 10 hinged to a casing (not shown) capable of vertical rotation, a core plate 20 connected to the core base 10, a core plate 20 mounted on the core plate The rotating shaft motor 21 that is used to provide the rotating force for disc 1 on the 20, the turntable 23 that is used for accommodating disc 1 on the rotating shaft 22 that is connected on the rotating shaft motor 21, one is installed on the upper inner surface of the shell facing the turntable 23. A holder 40 for fixing the disc 1 placed on th...
