Problems solved by technology

[0008] 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

[0036] Such as figure 2 As shown, the disc player according to the preferred embodiment of the present invention includes: a movement base 50, a movement board 70 elastically connected to the movement base 50, and a buffer inserted between the movement base 50 and the movement board 70 Piece 60, rotating shaft motor 100 installed on the movement board 70, the turntable 200, the optical head 75, the clamper 300 installed facing the turntable 200 to clamp the disk 1 placed on the turntable 200, and to prevent The self-compensating dynamic balancer 400 of the eccentric rotation of the shaft 130 of the shaft motor 100 caused by the eccentricity of the center of gravity of the disk 1.

[0037] The movement board 70 receives the external impact slowed by the cushion 60 via the movement base 50. Therefore, in order to reduce the external vibration transmitted from the movement base 50, the cushion 60 is preferably made of a material with low rigidity such as Made of materials such as so...

Abstract

The invention provides a clamper with a disk player having a self-compensating dynamic balancer. The self-compensating dynamic balancer is formed integrally with a clamper. The self-compensating dynamic balancer includes at least one race which is integrally formed with the clamper and rotates around a rotational shaft, a mobile unit which is located in the race to be capable of moving, and a cover member for covering an opening of the race.

Description

[0001] This application is a divisional application of the Chinese patent application entitled "Disc Player with Self-compensating Dynamic Balancer" filed by Samsung Electronics Co., Ltd. to the Chinese Patent Office on October 9, 1997. The application number is 97120700.3. Technical field [0002] The invention relates to a holder for a disk player, and more particularly to a holder for a disk player equipped with a self-compensating dynamic balancer. Background technique [0003] Generally speaking, a disc player records and / or reproduces information on / from recording media such as compact disc (CD), CD-ROM, and digital versatile disc (DVD). Due to its sensitivity, the disk player is required to protect the disk and optical head from external shocks and internal vibrations. [0004] Such as figure 1 As shown, a typical disc player includes a movement base 10 hinged to a housing (not shown) capable of vertical rotation, a movement board 20 connected to the movement base 10, and ...
