Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a medium dust removal device for removing dust attached to an optical disk, which is a disk-shaped recording medium used in an optical disk device.

[Conventional technology]

If dust adheres to the surface of an optical disk, which is the recording medium of an optical disk device, it may block the laser beam used for writing or reading (read/write), resulting in errors in writing or reading. The surface must be kept clean at all times. For this purpose, a media dust removal device is used, but conventional media dust removal devices have the function of removing dust attached to a rotating medium by bringing it into contact with a rotating brush. Only.

[Problems to be solved by the invention] As mentioned above, the conventional media dust removal device
Although dust attached to the medium can be removed, there is no dust collection function to collect the removed dust, so the removed dust may adhere to the medium again or adhere to the lens surface of the optical head, adversely affecting read/write operations. There is a drawback.

The purpose of the present invention is to eliminate the drawbacks of the conventional media dust removal device as described above by providing a mechanism that collects the dust removed from the media in the dust collection cover, so that it can be returned to the media or optical head. It is an object of the present invention to provide a medium dust removing device that prevents the adhesion of dust and allows an optical disk device with high read/write reliability to be obtained.

[Means for solving problems]

The media dust removal device of the present invention includes a cylindrical rotating brush, a bracket that horizontally supports the rotating brush at both ends thereof, and a slit that surrounds the front, rear, and bottom of the rotating brush and has a slit in the front part. The dust collecting cover is fixed to the bracket, and the filter is attached to the front part of the dust collecting cover having the slit.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are a perspective view and a side view of an embodiment of the present invention.

Referring to FIGS. 1 and 2, a cylindrical rotating brush 1 is horizontally supported at both ends by brackets 2, and is rotatable in the direction of arrow A (see FIG. 2). A dust collection cover 3 is fixed to the bracket 2 in a shape that surrounds the front, rear, and bottom of the rotating brush 1, and a slit 3a is provided in the front part of the dust collection cover 3 (see Fig. 1). . A filter 4 is attached to the front part of the dust collecting cover with the slit.

The media dust removal device configured as described above is
The medium 5 rises while rotating together with the bracket 2.
The rotating brush 1 removes the dust adhering to the medium 5.
remove it by adhering to it. Most of the removed dust enters the dust collection cover 3 fixed to the bracket 2. The dust that has entered the dust collection cover 3 is removed by the air flow generated by the rotation of the rotating brush 1 in the direction of arrow A in FIG.
The dust flows toward the dust collecting cover 3 through the slit 3a.
flows out (arrow B). At this time, dust adheres to the filter 4 and is removed. Therefore, medium 5
The dust removed from the media may attach to the medium 5 again, or
It does not scatter in all directions and adhere to the head of the optical lens.

[Effect of idea]

As explained above, the present invention prevents the dust once removed from the medium from adhering to the medium or the optical head again by drawing the dust removed by the rotating brush into the dust collection cover and depositing it on the filter. Therefore, read/write errors due to contamination of the medium or optical head can be reduced, and an optical disk device with excellent reliability can be obtained.
