Embodiment Construction

[0024] The structure of the present invention is described in detail below with reference to the preferred embodiment of the turntable device of the optical disc drive:

[0025] according to image 3 and Figure 4 As shown, the spindle motor 30 provides rotational driving force to the optical disk, and the pickup base (not shown) is fixed on the lower end substrate 34 thereof. The driving force of the spindle motor 30 is transmitted to the outside through the rotating shaft 32 .

[0026] The above-mentioned rotating shaft 32 is provided with a fixed brake 40, and the fixed brake 40 forms a cylinder hole 42 through the upper and lower parts of the center. On the fixed brake 40, the mounting surface 45 of the supporting turntable 50, which will be described below, protrudes according to a specified height. . Key portions 47, 47' protrude from the mounting surface 45, and they are installed symmetrically on both sides of the cylinder hole 42 as the center. This brake 40 is pr...

Abstract

The invention is a kind of revolving device of CD driver, it includes: fixed arrester which is fixed on the previous axis of rotation; the rotating plate which rotates with the axis of rotation which is set on the arrester; stretch component which is on the top of the plate and has stretch effect on the plate. The invention can form the right angel in actual action without controlling the right angel of plate and the rotation axis of main axis electrical machine, so it can upgrade the stability of the CD driver, and reduces the manufacturing cost.

Description

(1) Technical field [0001] The invention relates to a turntable device of an optical disc drive, in more detail, it is a turntable device of the optical disc drive which rotates together after a disc is installed. (2) Background technology [0002] figure 1 It is a plan view of the structure of an optical pickup head base (pick-up bose) of an optical disc drive in the prior art. As shown in the figure, an optical pickup head 3 that performs linear reciprocating motion is arranged on the optical pickup head base 1 . On the main base of the above-mentioned pick-up head base 1, the rear end is the center and its front end will lift by a prescribed angle, which is generally not shown on the figure. [0003] The optical pickup 3 detects the light reflected from the signal recording surface of the optical disc, and reproduces the signal recorded on the signal recording surface of the optical disc or the recorded signal. The optical pickup 3 is guided by the pickup guide shafts 4...
