JPH0482068A - Disk medium cleaner - Google Patents

Abstract

PURPOSE:To enable a user to recognize the position, to which cleaner liquid should be dropped on a wiping cloth on the inner peripheral side of a groove, at sight, by providing concentrically an annular groove with a rotating shaft on the sticking face of a sponge. CONSTITUTION:A cleaner pad 1 consists of a wiping cloth 2, a both-sides tape 3, and a sponge 4, and a circular groove 5 is provided concentrically with one end of the cylindrical sponge 4. The section of this groove is U-shaped. The wiping cloth 2 is stuck to the surface provided with the groove 5 of the sponge 4 with the both-sides tape 3 between them in the conventional manner. Thus, the position to which cleaner liquid should be dropped on the surface of the wiping cloth on the cleaner pad is recognized when cleaner liquid is dropped to the wet pad.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disk medium cleaner used in an optical disk device.

[Conventional technology]

In the conventional disk medium cleaner, as shown in FIG.
was attached to one end of a cylindrical sponge 4 with double-sided tape 3.

When using this secondary disc media cleaner as a wet type, a few drops of the cleaner liquid are placed on the surface of the wiping cloth 12 of the cleaner pad 11, and the cleaning cloth is brought into contact with and slid on the surface of the disc media, so that it adheres to the media surface. Peel off dust, etc. and remove dirt. This cleaner pad is called a wet pad.

Next, in order to completely remove the separated dust, etc. and the cleaner liquid attached to the disk medium surface, the surface of the disk medium is cleaned again using the cleaner pad 11 that does not drip the cleaner liquid, and the dust and cleaner liquid are removed. do. This cleaner pad 11 is called a dry pad.

In this manner, conventional disk medium cleaners alternately use a wet pad and a dry pad to remove dust and the like adhering to the surface of the medium.

[Interlayer point to be invented or solved]

As mentioned above, when conventional disk media cleaners are used for wet cleaning, a wet bat and a dry pad are used together for cleaning, so at least two or more cleaner pads are required. . Also, when dropping cleaner liquid onto a wet pad, it is difficult to know where on the surface of the wiping cloth of the cleaner pad it should be applied, and if too much is dripped, the cleaner liquid will permeate the entire surface of the wiping cloth. There was a drawback.

[Means to solve the problem]

The disk medium cleaner of the present invention includes a cleaner pad having a cylindrical shaped sponge and a wiping cloth attached to one end of the sponge via double-sided tape, and the disk medium rotating with respect to the cleaning cloth and the cleaning cloth of the cleaner pad. In the disk medium cleaner that removes dirt from the surface of the disk medium by sliding action with a wiping cloth, the sponge has an annular groove on the attachment surface thereof and coaxially with the rotation axis.

〔Example:· Next, the present invention will be explained with reference to the drawings.

FIG. 1(a) is a perspective view showing one embodiment of the present invention.

In FIG. 1(a), the secondary disk medium cleaner of the present invention has a cleaning pad consisting of a wiping cloth 21, double-sided tape 3, and a sponge 4, and one end of the cylindrical sponge 4 has a coaxial circular groove 5. It is provided. This groove 5
has a U-shaped cross section. The surface of the sponge 4 having the grooves 5 is attached via a wiping cloth 2 or double-sided tape 3, as in the conventional case.

FIG. 1(b) is a top view showing the sponge 4 of the present invention. In FIG. 1(b), when the media cleaner of the present invention is used, the inner periphery of the groove 5 provided on the reach pad 1 is used as a wet part 6 during cleaning, and the outer periphery of the groove is used as a dry part 6. Used as part 7. That is, cleaning is performed by dropping a cleaner liquid onto the wet use section 6, and removes the dust etc. adhering to the surface of the disk medium with the wiping cloth 2 impregnated with the cleaner liquid of the wet use section 6, and removes the peeled dust etc. The cleaner liquid adhering to the surface of the medium is completely wiped off with the wiping cloth 2 of the dry use section 7. The cleaner liquid dropped onto the wet type use part 6 does not penetrate into the dry type use part 7 because of the groove 5 provided on the cleaner pad 1.

Note that the shape of Section 5 does not necessarily have to be circular;
Furthermore, it goes without saying that the cross-sectional shape does not have to be U-shaped.

〔Effect of the invention〕

As explained above, the present invention provides a circular groove with a zero-shaped cross section on the cleaner pad, so that it is possible to easily drip the cleaning liquid onto the wiping cloth on the inner circumferential side of the groove. Moreover, since the groove is provided, the cleaner liquid dropped on the inner circumferential side of the groove will not penetrate into the wiping cloth on the outer circumferential side of the groove. Further, when performing cleaning, there is an effect that wet and dry cleaning can be performed simultaneously with one cleaner pad.

Claims (1)

[Claims] A cleaner pad having a cylindrical sponge and a wiping cloth attached to one end of the sponge with double-sided tape is provided, and the sliding action of the disk medium rotating with respect to the wiping cloth of the cleaner pad causes The disk medium cleaner for removing dirt from the surface of the disk medium, characterized in that the sponge has an annular groove coaxially with the rotation axis on the attachment surface of the sponge.
