Embodiment Construction
[0036] 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 .
[0037] 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...
