Description

[Detailed Description of the Invention] [Summary] This invention relates to an optical disk cleaning device that cleans dirt adhering to the surface of an optical disk, without damaging or charging the disk.
The purpose of the present invention is to provide an optical disc cleaning device that can remove dirt attached to a disc, and includes an antistatic means that prevents the optical disc from being charged, a feeding section that feeds out a cleaning cloth, and a collecting section that collects the fed cleaning cloth. , a cleaning means including a pressing part provided between the feeding part and the collecting part and pressing the cleaning cloth against the optical disk.

[Industrial Field of Application] The present invention relates to an optical disk cleaning device that cleans dirt adhering to the surface of an optical disk.

Data is written to and written to an optical disk optically. Therefore, if dirt such as oil, dust, or fingerprints adheres to the light incident surface, it will interfere with data writing/reading.

Furthermore, unlike generally used magnetic disks, optical disks are often used as replaceable recording media, so there is a high possibility that the above-mentioned stains will adhere to them. Therefore, there is a need for an apparatus that can easily remove dirt from optical discs.

[Prior Art] Next, the conventional technology will be explained. Conventionally, when an optical disc becomes dirty, it is wiped off with a clean cloth. Recently, simple cleaning devices have also been developed.

FIG. 7 is a block diagram of a conventional disk cleaning device. In the figure, 1 is a disk, 2 is a set of rollers that hold the disk 1, and 3 is a pressure means that presses one of the rollers 2 in the direction of the disk.

And these rollers 2. Drive roller 4 An adhesive belt 6 is wound around the turn roller 5.

7 is a cleaning tank filled with cleaning liquid power 1 for removing dust etc. attached to the adhesive belt 6, 8 is provided in each cleaning tank 7, and vibrates the adhesive belt 6 on which dust has adhered to remove the dust. An ultrasonic oscillator 9 is provided in each cleaning tank 7 and is a circulation filter that collects dust in the cleaning liquid.

Next, the operation of the above configuration will be explained. The disk 1 is held between a pair of rollers 2 which are pressed by a pressure means 3. Then, when the drive roller 4 is driven, the adhesive bell l-6 rotates and slides into contact with the disk 1, and dirt such as dust on the disk 1 is attached to the adhesive belt 6 and collected.

The adhesive belt 6 with dust etc. attached thereto enters the cleaning tank 7. Here, the ultrasonic oscillator 8 separates the dust adhering to the adhesive belt 6 from the adhesive belt 6 into the cleaning liquid. Then, the dust in the cleaning liquid is removed by the circulation filter 9.
It will be collected.

[Problems to be Solved by the Invention] Among the above-mentioned conventional examples, when wiping an optical disc with a clean cloth, the dirt may not be completely removed, the optical disc may be damaged by dust attached to the cloth, or the optical disc may be damaged. If the optical disc is made of plastic, there is a problem in that the disc itself becomes electrically charged, making it more likely to get dirty.

On the other hand, even in the case of a cleaning device, it is impossible to completely collect dust, and the adhesive belt 6 with dust attached may come into sliding contact with the disk 1 again, staining the disk 1, or
There are problems that can cause damage.
