DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board for displaying sheets such as posters and photographs, and a protective cover for circulating and storing such sheets.

[0002]

2. Description of the Related Art When displaying a sheet-like material such as a poster or a photograph on a board,
As a sticking means, a thumbtack or an adhesive tape is used. In this case, there is a problem in that pin holes are formed in both the board and the sheet-like material, and a peeling mark of the tape remains.

[0003] There is also a method of sandwiching and holding a sheet-like material between a board and a transparent plate. In this case, however, the transparent plate must be a glass plate or a thick synthetic resin plate which is not easily deformed, and the weight is reduced. It is bulky and increases costs. Also, it is not possible to stick a sheet-like material on a board while the board is standing. The board must be level and a sheet-like object placed on top of it, covered with a transparent plate and clamped to the board. The heavy transparent plate and board must be knocked or raised together, resulting in poor work efficiency. Correction of the position of the sheet-like object with respect to the board must be performed again by laying down the board, which is troublesome.

In order to circulate and temporarily store documents,
2. Description of the Related Art Documents are sandwiched in a case in which two soft transparent sheets are stacked. In the case, two adjacent sides of the two transparent sheets are welded, but the other two sides are open, so that the document may slip off the case when the document is moved.

[0005] As shown in FIG. 4, the applicant manufactures a display board in which a base film (2) subjected to electrostatic suction processing is adhered to a substrate (1), and a sheet-like material (6) to be displayed. Was placed on a base film (2) to attempt to electrostatically adsorb the sheet-like material (6). The sheet material (6) electrostatically attracted to the base film (2) does not slip off from the base film (2) even when the substrate (1) is erected. Also, sheet-like material
(6) was slid on the base film (2) while being pressed with fingers, and the arrangement and displacement could be corrected. However, as time elapses, the sheet-like object (6) becomes moist due to the sheet-like object (6) warping up from the outer peripheral edge, and the contact surface with the base film (2) decreases, and the display board becomes Was found to have a problem of peeling off.

The present invention is to clarify a display board and a protective case which solve the above-mentioned problem for display and storage of a sheet-like material such as a poster, a photograph, and a document.

[0007]

According to the present invention, there is provided a board (4) for exhibiting a sheet-like material, wherein a synthetic resin base film (2) is adhered to a substrate (1), and a synthetic resin transparent pressing film (4) is attached to the base film. 3) is covered so as to be able to be turned up, and at least the base film (2) is subjected to an electrostatic attraction process.

Further, the sheet-like material protective cover of the present invention (5)
In this method, a synthetic resin base film (2) and a synthetic resin transparent pressing film (3) are overlapped so as to be rolled up, and at least the base film (2) is subjected to electrostatic processing.

[0009]

[Functions and Effects] The holding film (3) is wound up and a sheet (6) such as a poster, a photograph, a document, etc. to be displayed or stored on the base film (2) is placed. Base film
The sheet-like material (6) is attracted to the base film (2) by the electrostatic attraction action of (2), so that it does not slip off from the base film (2).

However, since the sheet-like material (6) can be slid on the base film (2) while holding it with fingers,
The arrangement can be freely determined while moving the sheet material (6) on the base film (2), and the displacement can be easily corrected.

Pressing film from above sheet (6)
(3) is put on the base film (2). Holding film
(3) is also adsorbed to the base film (2), and the pressing film (3) comes into close contact with the base film (2) and the sheet material (6). As a result, the sheet material (6) becomes wet,
The outer peripheral portion is effectively prevented from warping, and the sheet-like material (6) does not slide down between the base films (2) even after a lapse of time.

Since the pressing film (3) is transparent, the sheet-like material (6) can be seen through the film.
The sheet-like material (6) is protected by the pressing film (3) and is prevented from directly touching the fingers, so that the sheet-like material (6) can be prevented from being stained or damaged. Since the base film (2) and the protective film (3) are thin films made of synthetic resin, the display board and the protective cover can be formed lightweight.

[0013]

FIG. 1 shows the present invention applied to a rectangular display board (4) for displaying a poster or the like.
The display board (4) has a synthetic resin base film (2) having an electrostatic attraction property attached to the substrate (1), and the synthetic resin transparent pressing film (3) is put on the base film (2). In the embodiment, the substrate (1), the base film (2) and the pressing film (3) have the same vertical length and the same horizontal length.

The substrate (1) is formed of a foamed synthetic resin plate, a corrugated cardboard sheet, a veneer plate or the like, and has a constant shape without a frame.

The base film (2) is obtained by subjecting a polyester film having a good electrostatic attraction property to an electrostatic attraction process, and has a thickness of about 75 μm. In the examples, a commercially available electrostatic adsorption film manufactured by Kimoto Corporation was used. The base film (2) is entirely adhered to the substrate (1) with an adhesive.

The pressing film (3) is a synthetic resin film such as polyester or polypropylene and has a thickness of about 50 μm. The holding film (3) has a base film on one side
The corresponding side of (2) is joined by heat welding or the like, and three sides are open.

Then, the pressing film (3) is turned up, and a sheet material (6) such as a poster or a photograph to be displayed is placed on the base film (2). Due to the electrostatic attraction of the base film (2), the sheet (6) is turned into the base film (2).
Therefore, even if the display board (4) stands up, it does not slip off the base film (2).

However, since the sheet-like object (6) can be slid on the base film (2) while holding it with fingers, the sheet-like object (6) can be slid on the base film (2) to be freely arranged. , And the displacement can be easily corrected.

Pressing film from above sheet (6)
(3) is put on the base film (2). Holding film
(3) is also adsorbed to the base film (2), and the pressing film (3) comes into close contact with the base film (2) and the sheet material (6). As a result, the sheet material (6) becomes wet,
Preventing the outer periphery from warping due to moisture,
Even if time passes, the sheet-like material (6) becomes the base film (2)
It does not slide down between the base film and the base film (2).

Since the pressing film (3) is transparent, there is no problem in viewing the sheet-like material (6). Sheet (6)
Is protected by the pressing film (3), which prevents the viewer from directly touching the sheet (6).
(6) Dirt and damage can be prevented.

Is shown. Both the protective cover (5) in FIGS.
The transparent pressing film (3) made of synthetic resin is formed on a synthetic resin base film (2) having electrostatic attraction so as to be rolled up. In the protective cover (5) of FIG. 2, one side of both films (2) and (3) is joined by heat welding or the like, and three sides are open. Figure 3 Protective cover (5)
(2) Two adjacent sides of (3) are joined by heat melting or the like, and the other two sides are open.

When the sheet (6) is sandwiched between the films (2) and (3) of the protective cover (5), the sheet (6) is electrostatically attracted to the base film (2) in the same manner as described above. The pressing film (3) prevents moisture and prevents warping from the base film (2).

In carrying out the present invention, the display board shown in FIG.
(4) In the protective cover (5) of FIGS. 2 and 3, the pressing film (3) can also be subjected to an electrostatic suction process to be attracted to the base film (2). 6) is adsorbed to the holding film (3), and both films
(3) Since (4) is strongly adsorbed to each other, the holding force on the sheet-like material (6) is further increased.

In practicing the present invention, the protective film (3) can be simply put on the base film (2), and a part of the protective film (3) is joined to the base film (2) as described above. It is not a mandatory configuration.

The present invention can also be applied to a photo album, in which the substrate (1) is used as a mount for an album, and the base film is attached to the mount.
