Problems solved by technology

However, since an elastic body 140 must be added, the cost of the element is increased, and the elastic element 140 must be connected between the base 120 and the carrier member 130 through an additional manufacturing process, which increases the assembly time of the optical drive and reduces the efficiency.
In addition, once the elastic body 140 is deformed due to factors such as material variation or elastic fatigue, it may affect the stability of the movement of the bearing member 130

Embodiment Construction

[0022] See Figure 4 , illustrating the structure of an optical drive carrying an optical disc according to an embodiment of the present invention. The mechanism of the optical drive 1 carrying the optical disc 60 of the present invention is similar to the existing structure, including the organic core 10 , the base 20 and the carrying member 30 . Wherein, the movement 10 has a motor 12 for rotating the optical disc 60 and a turn table 14 for carrying the optical disc 60 . The base 20 serves as the basic structure of the optical drive 1, and has an elastic portion 22 and a guide portion (not shown), wherein the guide portion can be as follows: Figure 2b The guide chute 122 in the prior art structure shown.

[0023] In addition, the carrying member 30 is movably connected to the base 20 for carrying the movement 10 . The bearing member 30 of this embodiment can be referred to Figure 5a As shown, it is a swing bearing member, which has a guided part (such as a chute) corre...

Abstract

The present invention relates to an optical drive, including a machine core, having a motor foe rotating an optical disk and a rotary disk for bearing said optical disk; a base seat, having an elastic portion and a guide portion, in which said elastic portion is a spherical form; and a bearing member for bearing said machine core. Said bearing member has a guided portion correspondent to said guide portion and a matching portion correspondent to said elastic portion, said guide portion can be used for guiding said guided portion, and can make said bearing member move between a first portion and a second position.

Description

[0001] The present invention is a divisional application of the Chinese invention patent application (application number: 02119388.6, application date: May 15, 2002, invention name: bearing member of the optical drive core). technical field [0002] The invention relates to a bearing component of an optical drive core, in particular to a bearing component of an optical drive core capable of reducing resonance and noise. Background technique [0003] In recent years, the use of optical drives and compact discs has become increasingly common. At present, the shapes of optical discs sold on the market tend to be diversified. In addition to the traditional circular optical discs, various non-circular optical discs have appeared, such as business card-shaped optical discs or patterned optical discs; and due to the large number of manufacturers, the quality The discrepancy is also large, so that the optical disk often produces an ecc...
