DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a television, a personal computer,
The present invention relates to a cleaner that can efficiently clean the surface of a screen portion of a display device such as a CAD or a CAM without damaging the surface.

[0002]

2. Description of the Related Art Conventional televisions, personal computers, CAD, CAM
Cleaning of the surface of the screen portion of a display device such as the like has been performed using woven fabric, thin paper, or the like. However, the glass surface and the fabric or thin paper are charged with static electricity due to friction when wiping,
In many cases, dust was not removed well and cleaning was time-consuming.

Further, the surface of the screen becomes uneven due to the way of holding the fabric and the thin paper, and the cleanliness of the surface of the screen portion such as a cathode ray tube is uneven. Therefore, it is necessary to repeatedly wipe the surface.

[0004]

SUMMARY OF THE INVENTION The present invention provides a cleaner capable of efficiently cleaning the surface of the screen portion of a display device such as a television, a personal computer, a CAD, and a CAM, and preventing the glass surface from being damaged. The purpose is to do.

[0005]

(1) In a cleaner for cleaning the surface of a screen portion of a display device such as a television, a personal computer, a CAD, a CAM, etc., a surface layer is partially or entirely entangled with fibers on the surface or inside. Or an ultrafine synthetic fiber cloth having fine loops, and the intermediate layer is made of paper mixed with conductive fibers such as carbon fibers, metal plated fibers, or metal fibers, or nonwoven fabric mixed or coated with conductive fibers. And
A cleaner characterized in that a laminate in which an inner layer is made of a cushion material such as a sponge is formed in a cylindrical body having a circular or polyhedral cross section.

(2) The cleaner according to the above (1), wherein the cylindrical member is rotatably supported by a handle, and the surface to be used can be switched by rotating the cylindrical member.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The cleaner of the present invention has a single fiber fineness of 2 deniers or less, more preferably 0.01 to 1 denier on the surface layer.
0.5 denier ultra-fine synthetic fiber woven, knitted,
Alternatively, a fabric such as a non-woven fabric is used, in which some or all of the fibers are entangled on the surface or inside, or have a fine loop on the surface. The entanglement and the fine loop can be obtained by so-called water jet punching in which the fabric is treated by applying a high-pressure water flow to the fabric from the small holes.

According to the present invention, the use of the cloth thus processed is applied to the surface of the cleaner roller, so that fine dust adhered to the glass surface and oil stains such as hand grit are scraped off by entanglement of the fine synthetic fibers and fine loops. It is. Therefore, it is possible to wipe even a stained portion that cannot be removed with a conventional cloth or thin paper.

Next, as the inner layer of the ultrafine synthetic fiber cloth, paper made by mixing conductive short fibers such as carbon fiber, metal plating fiber, or metal fiber, or nonwoven fabric mixed or coated with conductive fiber is used. Since it is interposed and neutralizes and prevents the generation of static electricity due to friction between the cleaner and the screen, dust can be easily and cleanly wiped off.

The reason why the neutralization phenomenon can be imparted is as follows. That is, when conductive short fibers such as the carbon fiber, metal-plated fiber, and metal fiber are present, the tip of these short fibers plays the role of an antenna where there is an electrostatic charging band, and counter ions are emitted from the air. Due to the physical phenomenon of collecting and neutralizing the charged body, no matter how much friction is applied to the surface of the cleaner, no electrostatic charge occurs.

Here, the neutralization phenomenon means (1) the presence of a charged material, (2) the opposite ions are collected at the tip of the conductive short fiber, and (3) the positive and negative ions are neutralized.
(4) A physical phenomenon in which static electricity decreases.

The electrostatic neutralization characteristics are measured by the following measuring method. (1) The charge amount of the charged material is measured with a static electricity meter manufactured by Shisido Electric Co., Ltd. (2) The cathode ray tube is wiped three times with the cleaner of the present invention to measure the charging status. (3) The amount of charge when the CRT is wiped with a cleaner cloth until it is as clean as (2) is measured.

As the conductive short fibers, PAN-based (polyacrylonitrile-based) carbon fibers, pitch-based carbon fibers,
Alternatively, metal-plated fibers, metal fibers, or a mixture of these fibers can be used.

[0014] It is preferable that the conductive short fiber be as thin as possible, and the fiber length be as long as possible, since ions can be easily collected. Specifically, a fineness of 0.5 to 3 denier and a length of 1 to 25 mm can be preferably applied. When the fineness is smaller than 0.5 denier, the strength is weak and the cost is increased. When the fineness is larger than 3 denier, the ion gathering force is reduced, which is not preferable. The fiber length is 1mm
If the length is shorter, the ion gathering force is reduced, and if the length is longer than 25 mm, the particles are undesirably dispersed in the paper and deteriorate.

According to the present invention, the conductive fiber is
Paper containing 0.2 to 50 weight percent or a coating fabric is incorporated in the second layer of the cleaner roller.

If the amount of the conductive short fibers is less than 0.2% by weight based on the whole, the effects intended by the present invention cannot be obtained. On the other hand, if it exceeds 50% by weight, the material cost becomes high, and papermaking and coating become difficult, which is not preferable.

The above-mentioned conductive short fiber is made by a wet papermaking method using a mixed material containing a wood valve and a binder.
The second layer of paper or nonwoven sheet can be obtained by coating a synthetic fiber nonwoven or the like in a state of being mixed with a binder.

When making paper, do not apply heat and pressure to hinder the projection of the conductive short fibers. Also, when coating, dry the coating side and lightly contact the coating side with sandpaper. It is good to protrude.

The central portion of the roller is made of an elastic cushion material such as sponge, urethane foam resin or polyurethane resin. The pressure and impact force at the time of wiping can be absorbed by using a roller made of such a cushion material.

In the present invention, a laminate comprising the members constituting the surface layer, the intermediate layer, and the inner layer is referred to as having a cross section of a circle, a triangle,
It is formed in a polygonal cylindrical shape such as a square or a pentagon, or is wound so as to be replaceable around a cylindrical surface having a cross section formed in a polygon such as a circle, a triangle, a square or a pentagon.
The roller is provided with a handle (grip handle, etc.) for rotatably supporting the roller with one or both ends, and has a weight that can be held with one hand. Also, a stopper may be provided to press the roller surface during use and prevent the roller from rotating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In using the roller device shown in FIG.
A high-density water stream is applied to a woven fabric composed of a very fine polyester multifilament of 0.05 denier to form entanglement on the surface and inside of the woven fabric.
