DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cleaner for cleaning an optical disk.

[0002]

2. Description of the Related Art Conventionally, there are disk cleaners described in Japanese Patent Application Laid-Open Nos. 2-239,489 and 2-304,787. These disk cleaners have a spindle motor for mounting and rotating an optical disk to be cleaned, and a rotating cleaning pad. While rotating the optical disk, the rotating cleaning pad slides against the surface of the optical disk to remove dirt. Configured to remove.

As shown in FIG. 5, the cleaning pad 20 is formed by adhering a wiping cloth 23 to one end surface (an upper end surface in FIG. 5) of a short cylindrical sponge 21 with an adhesive or an adhesive tape 22. ing.

[0004]

In this conventional disk cleaner, when removing dirt or the like adhering to the disk surface, the adhesive protrudes from the outer periphery of the pad, or the pad is insufficiently mounted, and the adhesive is removed. However, there is a problem that when the cleaning is performed while facing the disk surface, the adhesive adheres to the disk surface, and contaminates the disk surface.

[0005]

A disk cleaner according to the present invention comprises inserting a columnar sponge into a pad holder having a columnar inner wall surface, arranging a wiping cloth on the sponge, and cleaning the outer periphery of the wiping cloth. The cleaning pad has a cleaning pad fixed to a pad holder by a pressing ring.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1, the cleaning pad 9 of this embodiment includes a holding rig 91, a wiping cloth 92, a sponge 93, and a pad holder 96. One end face (lower end face in the figure) of the sponge 93 formed in a short columnar shape is inserted and mounted inside the pad holder 96. This mounting includes a method of completely bonding, a method of fixing by a frictional force due to the elasticity of the sponge 93, and a method of simply inserting. Adhesion can be completely fixed, but replacement of the sponge 93 is difficult. In any case, the attached sponge 93 slightly protrudes from above the pad holder 96. The wiping cloth 92 is covered so as to completely cover the protruding portion, and the holding ring 91 is attached from above. The holding ring 91 is fitted and mounted in the U-shaped groove 94 of the pad holder 96. That is, the ring 91 is attached to the wiping cloth 9
2 acts to press it into the groove 94. Therefore, the ring 91 is made of metal or plastic in a stretchable or partially cutout shape.

Next, a drive mechanism of the disk cleaner according to the present embodiment will be described with reference to FIGS. The spindle motor 8 is supplied with power from a drive circuit (not shown),
The spindle rotating shaft 7 is driven to rotate. The spindle turntable 5 is fixed to the spindle rotation shaft 7.
The optical disk medium 1 to be cleaned is mounted and fixed on the turntable 5. The optical disk medium 1 has a hub 2
The adsorbing metal 3 is provided through the intermediary. This adsorption metal 3
Is fitted to the spindle center shaft 4 so that the center of the optical disk medium 1 coincides with the rotation center of the spindle. A magnet 6 is provided on the turntable 5, and the optical disc medium 1 is fixed to the turntable 5 by the attraction between the magnet 6 and the attraction metal 3.

The cleaning pad 9 is supported by the cleaning pad holding unit 10 at a position where the cleaning pad 9 comes into contact with the loaded optical disk medium 1. This pad holding unit 10
It is fixed to a cleaning pad rotating shaft 11 and is rotatable by a cleaning pad rotating bearing 12. A pulley 13 is fixed to the rotating shaft 11, and the pulley 13 is connected to the spindle rotating shaft 7 by a belt 14. Therefore, the rotation of the spindle motor 8 is transmitted via the belt 14 and the like, and rotates the cleaning pad 9.

Next, the cleaning pad 9 shown in FIG.
Referring to FIG. 4, a description will be given of the engagement between the cleaning pad holder 10 and the cleaning pad holder 10 shown in FIG. As shown in FIG. 1, a projection 95 is provided on the cleaning pad 9. A groove 101 is provided in the holding portion 10 for the projection 95, and the projection 95 and the groove 101 are fitted and fixed. In the present embodiment, the projections 95 are a pair of columnar projections, but any number and shape can be applied.

[0010]

As described above, according to the present invention, since the wiping cloth is mounted without using an adhesive, the problem that the adhesive protrudes and adheres to the disk surface is eliminated. Further, since the anti-rotation mechanism is provided, there is no danger of the cleaner pad idling. Further, when the cleaner pad is mounted on the disk cleaner, since the mounting is performed by holding the outer periphery of the pad holder, there is no danger of crushing the sponge, and there is an effect that it is easy to handle.
