Patent application No. 10-2004-0112362 (December 24, 2004) relates to a disc drive device and a method of the disc drive, and is installed on the main base and the forward and reverse rotation of the loading motor to provide power for the disc transfer ; A roller which is installed on a roller link that rotates about a hinge axis on the main base and is rotated by a driving force of the loading motor and is in close contact with one surface of the disc to transfer the disc; A clamp plate provided at the front end with a clamp to fix the disk to a turntable installed on the main base and to be moved up and down about a hinge axis of the main base; A stopper provided to protrude to a lower surface of the clamp plate and regulating a position at which a disc of relatively small diameter is loaded; A cam lever configured to selectively receive and drive a driving force of the loading motor, and to lift and lower the hinge plate and rotate the roller link; The roller link is rotated at an angle before the clamp plate is lowered by the cam lever during the loading operation of the disk, so that the roller is separated from the lower surface of the disk so that the relatively large disk does not interfere with the stopper.

In the construction of such a disc drive, it is an absolute task to be able to hear clean sound quality, but the clamp plate for holding the disc loaded on the turntable during the playing of the disc interferes with the main chassis and generates friction sound. During the loading operation, various power transmission mechanisms interfere with each other, generate noise by generating friction noise, and cause a fatal problem as an acoustic device aiming for clean sound quality.

The present invention aims to solve such a problem that noise occurs in the disk drive thus far.

The present invention for achieving the above object is a turntable installed on the main base and rotating the disk; A loading motor mounted on the main base and forward and reversed to provide power for the transfer of the disk; A roller bar installed on the main base and driven by a driving force of the loading motor, and for loading or unloading a disk onto a turntable; A power transmission unit configured to selectively receive the driving force of the loading motor to control the roller bar; A clamp plate for holding the disk loaded on the turntable to stably rotate the disk; In the disc drive comprising: a pickup which reads and reproduces the disc record while moving in the centrifugal direction by driving the leading motor on the bottom surface of the disc which is loaded on the turntable and rotates.

Friction between the bottom of the clamp plate for holding the disk loaded on the turntable to rotate stably, the power transmission member for selectively controlling the roller bar by receiving the driving force of the loading motor, and the guide lever for controlling the entry and exit of the disk. The cushion filter is integrally formed at the portion to be joined.

At this time, the cushion filter is configured to be corrugated in a wave shape to adapt to the impact and friction gap, and to form a groove in the friction portion of the clamp plate and the power transmission member that interferes with a portion of the cushion filter is recessed in the groove. The cushion filter may be configured to be bonded to each other, or may be configured to be joined to a friction portion of a clamp plate or a power transmission member in which interference occurs by forming a “?” Shaped cross section.

 In the above-mentioned invention, in the disc loading device of the disc drive, the plates constituting the various drive mechanisms of the disc drive are installed adjacent to each other, where the friction pads constitute a boundary pad, and where they collide with each other. By constructing a shock absorber, the parts such as the power transmission member and clamp plate are not directly hit or rubbed to prevent noise generated when playing a disc or performing loading and unloading operations. It is a useful invention that creates new effects that cannot be realized in disk drives up to now, such as improving the reliability of the product.

Figure 2 is an exemplary view showing a guide lever configuration guides the entry and exit of the disk of the present invention.
Figure 3 is an exemplary view showing a cushion filter attached to the guide lever which is the main part of the present invention.
Figure 4 is an exemplary view of the pleated configuration of the cushion filter which is the main part of the present invention,
Figure 5 is an illustration of another configuration of the cushion filter which is the main part of the present invention.

Referring to the embodiment of the present invention configured in this way in more detail,

A turntable (10) installed in the main base (100) for rotating the disk; A roller bar 35 for loading or unloading the disk onto the turntable 10; A clamp plate (40) for holding the disk loaded on the turntable (10) to stably rotate; A guide lever 70 for controlling the entry and exit of the disc; In the disk drive consisting of: a pickup loaded on the turntable 10 to read and reproduce the record of the rotating disk,

The bottom surface of the clamp plate 40 for holding the disk loaded on the turntable 10 to rotate stably, the guide lever 70 and the gate of the guide lever 70 to control the entry and exit of the disk (D) The cushion filter 150 is integrally bonded to portions of the pin 71 that are rubbed with each other.

Here, the cushion filter 150 is configured to be corrugated in a wave shape to adapt to the impact and friction gap, and to form a groove 80 in the friction portion of the clamp plate 40 and the guide lever 70 in which interference occurs A portion of the cushion filter 150 is recessed and joined to the recess 80, or the cushion filter 150 is formed in a “c” shape on a cross section so that the interference between the clamp plate 40 and the guide lever 70 may occur. Connect to the friction part and join.

Referring to the embodiment of the present invention configured in this way in detail as follows.

When the roller plate 30 is operated to load the disk onto the turntable 10, the cushion filter 150 of the present invention operates the guide lever 70 to control the access of the disk while the guide lever 70 operates. It is possible to prevent the gate pin 71 configured in the above from hitting to suppress the generation of noise.

When the disk is loaded on the turntable 10 in the above state, the clamp plate 40 grabs the disk to play, and at this time, the cushion filter 150 integrally attached to the interference part of the clamp plate 40 is rubbed. This prevents the occurrence of friction noise.

In this case, when the recess 80 is configured to insert the cushion filter 150 into the interference portion with the clamp plate 40 or the guide lever 70 intercepting the entry and exit of the disk, the cushion filter 150 is the clamp plate 40. Or more securely attached to the guide lever 70 will not easily fall or damage.

In addition, when the cushion member 150 is configured to be corrugated in a wave shape, it is excellent in adaptability to impact and friction gaps and the effect will be doubled.

In addition, the cushion filter 150 is clamp plate 40 when the cushion filter 150 is formed in the cross-sectional shape of the letter “c” and inserted into the friction portion of the clamp plate 40 or the guide lever 70 where interference occurs. I will do my part without easily deviating from the guide lever (70).
