Problems solved by technology

However, in daily study and work records, information that does not need to be kept for a long time occupies a large proportion (such as exercise drafts, random work records, etc.). This kind of writing usually still uses pen and paper. All used pens and papers are thrown away, which causes a great waste of resources

Embodiment Construction

[0013] figure 1 It is a schematic structural diagram of a writing tablet according to an embodiment of the present invention. As shown in the figure, the writing board mainly includes a bottom plate 1 ; a surface film 2 ; and a paste 3 sealed between the bottom plate 1 and the surface film 2 .

[0014] The bottom plate 1 can be made of hard materials and the like. The surface of the bottom plate 1 is a surface with moderate smoothness, the first purpose is to slow down the flow velocity of the paste 3; the second is to make the surface film 2 fit closer to the bottom plate 1 under the action of the writing pen. Through experiments, it is advantageous that the surface finish of the bottom plate is equivalent to the finish of the paper surface.

[0015] The surface film 2 is a writing-resistant material, that is, it is not easy to be damaged under the repeated action of the writing pen. The surface film can be deformed under the action of the pen, but after the writing is com...

Abstract

The invention discloses a reusable writing board, comprising a base plate, a surface film and a paste-like body sealed between the base plate and the surface film, wherein the colour of the paste-like body is different from the that of the base plate, and the surface film is transparent and can cause the paste-like body to produce a writing trace under the action of a writing pen so as to display the colour of the base plate by virtue of the trace and the surface film. By utilizing the writing board disclosed by the invention, the beneficial effects that recording is conveniently repeated and the use of paper and pen is reduced can be realized.

Description

technical field [0001] The invention relates to a reusable writing board. It is suitable for writing and recording situations such as daily study, work and office, writing practice and recording random information. The information records mentioned here do not include computer records, electronic handwritten records and other means of recording using modern information technology. Background technique [0002] Writing is that the writer writes handwriting on writable items such as paper or board (such as writing on sand with a wooden stick) through various writable tools (such as brushes, pencils, and chalks). For daily study, office work, writing exercises and recording information, the general form is to write the content on paper. For important information that needs to be stored for a long time, this is undoubtedly the best way to use. However, in daily study and work records, information that does not need to be kept for a long time occupies a large proportion (such a...
