AI Technical Summary

Benefits of technology

The buffer element effectively reduces axial forces, preventing disk bouncing and ensuring stable ejection by absorbing the impact, allowing the disk to be ejected smoothly and preventing sticking with internal components.

Problems solved by technology

The buffer element interferes the disk when the disk is released from the pawl.

Embodiment Construction

[0025]Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0026]FIG. 1 and FIG. 2 are schematic views of a disk clamping apparatus according to one embodiment of the present invention. An optical disk drive 10 is disclosed herein, and the optical disk drive 10 includes a main body 200 and a tray 300 movably disposed in the main body 200 and a clamping apparatus 100. The tray 300 is moved along a direction of penetrating out of (or penetrating into) the figure, so as to send the disk 20 into or out of the main body 200.

[0027]The clamping apparatus 100 includes a base 110, a spindle assembly 120, a pawl 130 and a gasket 140. The base 110 is movably disposed in the main body 200 along an axis C1 to move toward or away from the tray 300. The spindle assembly 12...

Abstract

A clamping apparatus for being disposed in an optical disk drive and carrying a disk is provided. The clamping apparatus includes a base, a spindle assembly, a pawl and a buffer element. The spindle assembly is disposed on the base and rotating about an axis. The pawl is assembled to the spindle assembly. The disk is configured to be locked to the pawl, such that the spindle assembly drives the pawl and the disk to rotate about the axis. The buffer element is assembled to the spindle assembly, and the buffer element is located above the pawl. The buffer element interferes with the disk when the disk is separated from the pawl.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of China application serial no. 201310073216.6, filed on Mar. 8, 2013. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a clamping apparatus, and more particularly, to a clamping apparatus of an optical disk drive.[0004]2. Description of Related Art[0005]In recent years, optical disk apparatuses configured to be disk recording / reproducing apparatuses have been develop continuously. In general, an optical disk drive for driving an optical disk has become an indispensable tool for recording and regenerating the data in a personal computer (represented as computer hereafter), and can be built in the main body of the computer or externally connected to the main body of the computer by a cable. Generally speaking, an op...
