[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention is based on the idea that the user presses down on the surface of a translucent thin sheet with a protrusion to write a typeface, and the color of the underlaying receiving plate joined to this thin sheet is the typeface color. The present invention relates to an improvement in a writing plate which can be read out by being read.

[0002]

[Prior art]

 As shown in FIG. 6, a writing plate of this kind known in the prior art is a white or colorless transparent solid wax 1b which is easily melted by heating and is thinly applied to the surface 1a of a thin colored ball paper. Coated. The coated surface of the wax 1b of the cardboard receiving plate 1 is colored and printed, and the coated surface of the wax 1b of the receiving plate 1 is joined to a thin sheet 2 made of vinyl chloride or the like so that close contact and separation can be alternately performed. Can be

FIG. 6 shows a writing plate according to the prior art. That is, the wax 1b is applied to the colored printing surface of the receiving plate 1, and the thin receiving plate 1 serves as an underlay, and on the coating surface of the wax 1b, a milky white sheet 2 of a vinyl chloride film is formed. One side is closed and one side can be freely opened and closed in the direction of the arrow so that the notebook can be opened by joining.

In the writing plate configured as described above, when the user presses and writes on the sheet surface 2 b of the sheet 2 with the claw of a finger or the tip of a protrusion, the portion receiving the pressing force receives the receiving plate 1. Only the color tone of the colored and printed receiving plate 1 adhered to the wax 1b emerges along the written font on the sheet surface 2b so that the font can be read.

When erasing these written fonts, by separating the sheet 2 from the receiving plate 1, colored fonts that have emerged due to the pressing force can be erased.

[0006]

However, in the case of the above-mentioned prior art, however, a white or colorless transparent wax 1b which is thinly applied to a colored receiving plate 1 for an underlay is bonded to the film 1b on the surface of the wax 1b. The milky vinyl chloride sheet 2 is exposed to an environment of about 40 ° C. under a high temperature, so that the wax 1b is melted and the typeface is blurred, the typeface disappears spontaneously, and the wax 1b of the receiving plate 1 is removed. There is a problem that the transfer to the sheet 2 deteriorates the durability.

As described above, since the type 1 is written between the receiving plate 1 and the sheet 2 via the wax 1b, the heat resistance of the wax 1b is low. Failure to function at high temperatures such as direct sunlight during storage in warehouses or at stores causes the problem that temperature regulations must be specified for handling.

[0008] As described above, direct sunlight in a warehouse or at a store is very common in the midsummer at 50 ° C to 60 ° C, and the above-mentioned troubles are always expected. The point is that it has not been reached.

Next, since the joining medium between the receiving plate 1 and the sheet 2 is the wax 1b, there is a problem that the number of times of writing in a long time is small and the product life is very short.

[0010]

[Means for Solving the Problems]

 This invention is intended to solve some of the above-mentioned problems, that is, the deterioration of the function due to the melting of the wax 1b during storage in a high-temperature environment, the spontaneous disappearance of the writing typeface, the attachment of the receiving plate 1 and the sheet 2 and the addition of the sheet The purpose of this invention is to eliminate the dislocation of the wax 1b, increase the durability of the writing sheet 2, and extend the life of the product.

As shown in FIG. 1, the joint between the receiving plate 1 and the film-like milky white translucent sheet 2 joined and paired with the receiving plate 1 has been devised and improved. That is, the wax is removed from the joining portion of the surface 1a of the receiving plate 1 serving as an underlay with the sheet 2. The receiving plate 1 is processed with a molded product having a very small concave / convex grain. In the present invention, it is molded with a black coloring material of ABS synthetic resin, but it is natural that it is not necessary to specify the ABS synthetic resin by selecting a durable material.

As described above, the first condition of the receiving plate 1 is to remove the grain surface of the molded product, and in some cases, a sheet made of a vinyl chloride grain is applied to an iron plate such as a vinyl top. It can be a colored leather or a colored leather with a rough surface.

Next, in the first embodiment, the adhesive force of a polyimide adhesive tape which is commercially available as an adhesive tape is used as the sheet 2 in the first embodiment. , And the joining and separation are repeated.

As shown in FIG. 2, the user presses the sheet surface 2b of the sheet 2 bonded to the receiving plate 1 with the fingertip as shown in FIG. The writing font 2c emerges due to the adhesive force, but the font is sharply raised and the receiving plate 1 is colored black, and the sheet 2 is a white semi-transparent font in order to enhance legibility. Has good contrast.

Next, when erasing the typeface written on the sheet surface 2b written by the user, the written typeface 2C is erased by separating the sheet 2 from the receiving plate 1 as shown in FIG.

Next, a second embodiment of the present invention will be described with reference to FIG. 4. The sheet 2 'is a milky white semi-transparent film having a very fine grain portion 2d on one side, and a urethane adhesive sheet on the notebook opening. 3 and are joined openably and closably.

The transparent urethane adhesive sheet 3 having an adhesive force on its surface is attached to a flat plate-shaped molded article of ABS synthetic resin colored in black.

As described above, the user presses down on the sheet surface 2b ′ of the sheet 2 ′ having the grain 2d with a fingertip or the like to write a typeface, and the grain 2d of the portion that receives the pushing force becomes creased. The writing font 2C is adhered to the urethane adhesive sheet 3 and the writing font 2C emerges, and the black coloring receiving plate 1 penetrates through the film-like white coloring film-like sheet surface 2b '.

The fonts raised by these pressing forces are erased when the user separates the sheet 2 from the urethane adhesive sheet 3 in an open state.

[0020]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows the structure shown in a perspective view in the first embodiment. That is, the receiving plate 1 is made of an ABS resin molded product having a black color tone of ABS resin having a thin plate shape and a very fine grain on one surface, and the surface 1a with the grain is openable and can be freely opened and closed. A film-like translucent sheet 2 having a white color tone is joined and stacked.

When a user presses and presses the film-shaped sheet 2 to write a typeface, an adhesive 2 a applied to one surface of the sheet 2 is attached to the convex portion of the grain provided on the receiving plate 1, as shown in FIG. Then, a black typeface in which the writing typeface 2c is the color tone of the receiving plate 1 emerges.

In these film-like sheets 2, only the pressing portion is stuck to the convex portion of the grain of the receiving plate, and the font is embossed in the color tone of the receiving plate 1, or the portion without pressing force is applied to the convex surface of the grain. Due to the presence of a space in the concave portion of the grain, the front surface 1a of the white translucent sheet 2 always holds only the typeface.

Also, in order to enhance the visibility by embossing the color tone of the receiving plate 1 on the sheet 2 as described above, the color tone of the sheet 2 having a white tone and the color tone of the receiving plate 1 are combined colorfully. Of course, you may.

Next, a second embodiment will be described with reference to FIG. 4. In the first embodiment, the adhesive 2a of the sheet 2 is opened and closed on the front surface 1a of the receiving plate 1 provided with the grain by opening the notebook. In contrast to the writing and erasing of the typeface, in the second embodiment, a grain 2d provided on one side of the sheet 2 'is formed on a flat urethane adhesive sheet 3 coated with an adhesive. The writing font is protruded on the sheet 2 '.

Next, a third embodiment will be described with reference to FIG. 5. The sheet 2 in the first embodiment described above is divided into two parts, writing fonts are raised on each sheet, and each sheet is separately erased and written. However, the same writing can be performed in the second embodiment. (Not shown)

As described above, the embodiment in which the sheets 2 and 2 ′ are divided into two is described. However, it is needless to say that the sheet can be freely divided into three or more.

[0027]

[Effect of the invention]

 The present invention is configured and operates as described above, and has the following excellent effects. The adhesive has a much better high-temperature characteristic by constantly joining the grain between the film-like colored translucent sheets with the adhesive to be opened and closed on the underlying colored receiving plate The excellent heat resistance prevents the adhesive from melting due to the stock of the product or the heat of direct sunlight in a high-temperature environment, and the sheet and receiving plate from sticking to each other and losing the writing function. A writing plate can be provided.

In addition, since the typeface is embossed by bonding with no intervening wax and bonding of irregularities or combination of irregularities and the urethane adhesive sheet, there is no transfer or diffusion of the adhesive at high temperatures. Thus, a durable writing plate with a long writing life can be provided.

Further, as described in the second embodiment, the adhesion to the sheet utilizes the adhesive force of the urethane adhesive sheet, so that even if foreign matter is adhered to the adhesive, the surface of the urethane adhesive sheet is not covered with water. It can be wiped off with water or detergent, and can provide a writing plate with excellent adhesive strength at all times.

Further, as described in the third embodiment, since the sheet is divided into two, a writing plate capable of freely writing and erasing a portion can be provided.
