Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrostatic attraction plate used for surface panels such as bulletin boards and whiteboards.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, when a paper sheet or the like is posted on a bulletin board or a whiteboard, a means of fixing the upper and corner portions of the paper sheet or the like with an adhesive tape or a thumbtack has been used.

[0003]

[Problems to be solved by the device]

 However, in the conventional means, it is necessary to equip a bulletin board or a whiteboard with a fixing member such as an adhesive tape or a thumbtack, and it takes some time to fix and peel a paper sheet using this fixing member. In addition, there is a problem that the fixing member is easily lost, and in addition, the paper sheets and the like that have been posted overnight are soiled by the fixing member.

Therefore, in the present invention, the posted matter can be fixed without stains without the need for a fixing member such as an adhesive tape or a thumbtack, and the fixed / peeling of the posted matter can be extremely achieved. An object is to provide an electrostatic attraction plate that can be easily performed.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the electrostatic adsorption plate of the present invention has an electrostatic adsorption film on the surface of a non-magnetized synthetic resin thin plate or a non-magnetized iron thin plate made by mixing magnetic powder. It is characterized by being laid in one piece.

Further, a color sheet may be integrally laid between the thin plate made of synthetic resin or the thin plate made of iron and the electrostatic attraction film.

[0007]

[Operation] An electrostatic attraction plate is integrally laid on the surface of a non-magnetized synthetic resin thin plate mixed with magnetic powder or a non-magnetized iron thin plate. The thin paper sheet is brought into contact with the surface of the electrostatic attraction plate and the surface is lightly rubbed so that the paper sheet is attracted and fixed to the electrostatic attraction plate by static electricity. For thick paper, etc., the thick paper can be fixed between the magnet and the thin plate by arranging the magnet pieces on the paper that is brought into contact with the surface of the electrostatic attraction plate.

Further, when the color sheet is integrally laid between the thin plate made of synthetic resin or the thin plate made of iron and the electrostatic attraction film, the color of the color sheet is transferred through the transparent or semi-transparent electrostatic attraction film. To prevent the color of synthetic resin thin plates or iron thin plates from passing through.

【Example】

 In FIG. 1, the electrostatic attraction plate 1 of the present invention is magnetized with a thickness of about 1 mm, which is formed by mixing magnetic particles such as iron and ferrite in a high density and in a high density so that the magnet pieces can be magnetized. On the surface of a thin plate 2 made of synthetic resin material or a non-magnetized iron plate having a thickness of 0.1 to 0.3 mm and made of a resin film such as polyvinyl chloride and having a high electrostatic chargeability. The adsorption film 3 is integrally laid by means such as sticking or heat welding. The electrostatic attraction plate 1 can be used as it is, but can also be incorporated as a front panel such as a bulletin board or a whiteboard.

The thin plate 2 is only for exhibiting the function of attracting the magnet pieces, and does not need to be magnetized by itself.

When the electrostatic attraction film 3 is transparent or translucent, the color tone of the thin plate 2 is transmitted through the electrostatic attraction film 3, but the color tone of the thin plate 2 does not match a bulletin board or a whiteboard. If there is any, a color sheet 4 made of polyvinyl chloride or the like having a suitable color tone is integrally laid between the thin plate 3 and the electrostatic adsorption film 3 by means such as sticking or heat welding. Further, when the colored electrostatic adsorption film 3 such as milky white is used, the color sheet 4 is unnecessary.

By constructing the electrostatic adsorption film 3 from a resin film such as polyvinyl chloride, it is possible to perform the same function as a whiteboard in which the surface is drawn with a marker pen for whiteboard and then erased. it can.

According to the electrostatic attraction plate 1 of the present invention having such a configuration, the thin paper sheet 5 is brought into contact with the surface of the electrostatic attraction film 3 and the surface thereof is lightly rubbed so that the paper sheet 5 is electrostatically charged. Is adsorbed and fixed on the electrostatic adsorption plate 1. Further, in the case of thick paper or the like, the thick paper can be fixed between the magnet and the thin plate 2 by disposing the magnet piece on the paper which is in contact with the surface of the electrostatic attraction plate 1.

[0014]

[Effect of device]

 As described in detail above, according to the electrostatic attraction plate of the present invention, the electrostatic attraction film is integrally formed on the surface of the synthetic resin thin plate mixed with the magnetic powder or the non-magnetized iron thin plate. By laying it down, thin paper sheets, etc. are brought into contact with the surface of the electrostatic adsorption plate and lightly rubbed on the surface, so that the paper sheets are adsorbed and fixed to the electrostatic adsorption plate by static electricity. In the case of thick paper, etc., the thick paper can be fixed between the magnet and the thin plate by disposing the magnet piece on the paper brought into contact with the surface of the electrostatic attraction plate. As a result, the posted matter can be fixed without stains without the need for a fixing member such as an adhesive tape or a thumbtack, and the posted matter can be fixed and peeled very easily.

When a color sheet is integrally laid between the thin plate made of synthetic resin or the thin plate made of iron and the electrostatic adsorption film, the color tone of the color sheet is transferred through the transparent or semi-transparent electrostatic adsorption film. And a color of a synthetic resin thin plate or an iron thin plate with a limited color tone is blocked, and an electrostatic adsorption plate of any suitable color tone can be obtained by a color sheet.
