It has been transferred to the inside of, and because of such vibration may cause a malfunction of the turntable and the optical pickup device (3) is equipped with a damper for vibration absorption to solve this.

The damper is installed between the main frame and the main base to absorb vibrations transmitted to the main base, and this installation structure will be described with reference to the accompanying drawings as follows. Referring to FIGS. 1 and 2, damper seating grooves 1a are formed at corners of the main frame 1 so that the dampers 6 are fitted, and the inner diameter of the damper 6 is inserted into the main base 2. The bosses 2a penetrating the protrusions are formed to protrude, and the screws 7 are fastened to the bosses 2a to support the dampers 6 so that the dampers 6 do not fall out.

However, in the supporting structure of the damper for the conventional optical disc player, the screw 7 for supporting the damper 6 has a problem that the assembly work is very cumbersome and the productivity is lowered because the operator has to fasten directly using a tool.

The present invention was created to solve the above-mentioned problems, and effectively supports the damper for absorbing the vibration generated when the disk rotates, as well as simplifies the assembly process of the support member for the support of the damper to improve productivity. It is an object of the present invention to provide a support structure of a damper for an optical disc player.

The support structure of the damper for an optical disc player of the present invention for achieving the above object is provided between a main frame mounted on a PC or the like and a main base mounted on an upper side of the main frame, and equipped with a turntable and an optical pickup device, to vibrate. In the support structure of the damper for absorbing

A support member is rotatably formed in the main base, and the support member includes a vertical support portion and a horizontal support portion extending from a lower portion of the vertical portion to support the damper from below.

A fixing part is formed in the main base, and a horizontal fixing part is extended at an upper end of the vertical part of the supporting member, and the horizontal fixing part is preferably provided with a fixing protrusion fastened to the fixing part.

The support member is preferably injected in the main base.

Hereinafter, a preferred embodiment of the support structure of the damper for an optical disk player of the present invention as described above will be described in more detail with reference to the accompanying drawings.

Figure 3 is a view showing an operating state of the support member applied to the embodiment according to the present invention, Figure 3a is an initial state of the support member, Figure 3b shows a state in which the support member supports the damper, Figure 4 is a longitudinal sectional view showing an embodiment according to the present invention. For convenience of description, the same member numbers are assigned to the same constituent members as in the prior art.

As shown therein, the support structure of the damper for an optical disc player according to the present invention includes a main frame 1 having an upper side opening and a damper seating groove 1a (shown in FIG. 1) at a corner portion, and a corner portion. The boss 2b protrudes downward and is mounted inside the main frame 1, and the main base 2 is provided with a turntable (not shown) and an optical pickup device (not shown). The damper 6 is inserted into the damper seating groove 1a and is fixedly coupled to the damper 6 through which the boss 2b on the side of the main base 2 penetrates, and the damper 6 is rotatably coupled to the main base 2. It comprises a support member 10 for supporting.

The support member 10 is injection molded into the main base 2, and its shape is composed of a vertical support 11 and a horizontal support 12 extending from the bottom of the vertical support 11. The small diameter part 11a which penetrates the main base 2 is formed in the upper end part of the part 11, and is not separated from the main base 2.
