Embodiment Construction

[0030] Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0031] Such as Figure 4A to Figure 7 As shown, an optical disc drive according to one embodiment of the present invention includes: a main frame 110, an optical disc tray 120, and a ring formed between the main frame 110 and the optical disc tray 120 to prevent the optical disc tray 120 from vibrating due to external impact and / or optical disc rotation. Anti-vibration device.

[0032] The main frame 110 includes two side walls 111 , 112 and a rear wall 113 . The side walls 111, 112 have fixing grooves 111a formed in an appropriate position to fit elastic guides of an anti-vibration device 130, which will be described later. A loading mechanism that m...

Abstract

An optical disc drive having a vibration preventing device includes a main frame having sidewalls and a rear wall and guide rails inside the sidewalls; a disc tray with supporting steps to move to a disc loading / unloading position while supported by the guide rails to slide; and four elastic guides to absorb vibration of the disc tray by external impact and / or disc rotation by pressing and supporting the disc tray from up to down elastically, the elastic guides formed in the sidewalls to confront each other with a predetermined space. Since the elastic guides support the disc tray by pressing the disc tray in both sides of the back and front from up to down, the vibration of the disc tray may be prevented effectively. Although the disc tray is ejected to a disc unloading position, the disc tray is not shaken because the disc tray is still supported by two elastic guides.

Description

technical field [0001] The present invention relates to an anti-vibration device, and more particularly, to an anti-vibration device for preventing vibration of devices such as compact discs (CDs), digital versatile discs (DVDs) and the like, and to an optical disk drive incorporating the anti-vibration devices therein. Background technique [0002] In general, optical disk drives for recording information on optical recording media such as CDs and DVDs or reproducing information on optical recording media are excellent in reproducing data because these devices use a pickup unit in a non-contact manner. Record or reproduce data. However, optical disc drives using pickup units have a disadvantage in that they are less resistant to vibrations. In fact, the problem of damping and preventing vibrations has risen to become an important issue recently as the disc access times of optical disc drives have become even faster. [0003] Figure 1 to Figure 3 An optical disc drive inc...
