板ガラスに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in classrooms, offices, conference rooms, etc., and can be used repeatedly for writing with a general-purpose writing instrument and wiping and erasing with a character eraser such as a sponge. The present invention relates to a sheet glass functioning as a screen.

ガラスが開発されている。2. Description of the Related Art Conventionally, this kind of repetitive writing section village is indispensable especially for learning by a large number of people, business affairs, meetings, advertisements, messages, notices and the like. Many types have been developed depending on the application,
Blackboards that use chalk for writing instruments, white boards that use general-purpose writing instruments such as felt-tip pens, etc. are well-known,
In any case, although the functionality of being able to be used repeatedly is satisfied, the decorativeness and design required in recent years are extremely poor, and in contrast, a rough surface is formed on the surface of the sheet glass. There has been developed a new sense of sheet glass that can be written and erased using a water-soluble writing instrument such as a felt pen.

たものである。Accordingly, the present invention further improves the conventional sheet glass which can be written and erased by using a writing instrument, and devises the surface processing so as to function as a projection screen together with a writing member. It is an attempt to provide a new flat glass that allows a user to write on a projected image as a background.

生じた。However, if this type of conventional glass sheet is simply made to function as a projection screen, the conventional glass sheet simply obtains a click feeling on the rough surface of the glass sheet as shown in FIG. In addition, there is a problem that light is diffused so strongly on a rough surface that a sufficient image that can withstand visual observation cannot be obtained.

Thus, the rough surface having the continuous smooth mountain-shaped projections missing was made continuous, and an image could be formed on the rough surface when an image was projected onto any surface of the sheet glass. More specifically, by devising the rough surface,
A click feeling of the writing instrument is obtained at the bottom, and the top is smoothed to have a structure that can be easily erased when a water-soluble ink is applied, and also facilitates image formation. Also,
By making the translucent plate glass a colored glass, the color appearance of the entire image was simultaneously improved.

Is, for example, a colored transparent or colorless transparent quartz glass having a thickness of an oblong rectangle or the like, an opaque glass ceramic, a crystallized glass, and the like, sand blasting, shot blasting, physical processing such as gliding, etching on one surface. A translucent plate glass 1 having a rough surface 1a formed by a chemical treatment such as melting, porosification, strengthening, or a combination thereof, or a light-scattering coating treatment by printing, vapor deposition, plating, painting, or the like. The rough surface 1a may be formed in a stripe, a pattern, or the like over the entire surface of the plate glass 1 or only a part thereof.
Since the shape of the sheet glass 1 can be freely changed, it is preferable to form the sheet glass 1 in various combinations in consideration of design.

目視に耐え得る結像を可能としている。According to the present invention, the rough surface 1a is a rough surface in which a smooth mountain-shaped convex portion is formed by cutting off a top portion x of a substantially triangular convex portion formed by mechanical cutting by sand blasting. In addition, when an image is projected toward the back surface or the front surface of the plate glass 1, it is possible to form an image that can withstand visual observation on a rough surface.

される。More specifically, the rough convex portion has a top portion x which is so smooth that it can be easily erased when the water-soluble ink is applied, but at the same time, as shown in FIG. It has a surface portion for emitting incident light in a state of being almost parallel. As a result, the projected image is slightly blurred in the outline, but rather produces a fantastic decorative effect by this phenomenon, and is formed with a sharpness enough to be visually recognized.

乗効果が生じる。On the other hand, the bottom y of the rough surface 1a is formed as a slightly acute triangular groove, so that a click feeling can be obtained when the writing member is moved with the plate glass 1 in contact. The bottom portion y has a depth such that characters and designs written with a writing instrument such as a felt-tip pen can be easily erased with a character eraser such as a sponge or cloth. Synergistic effects such as easy-to-see and repetitive use and elimination of slippage when writing with a writing instrument are produced.

Not only a single sheet of single-layer glass, but also two sheets of glass 1 may be bonded to each other with an adhesive resin or the like to form a thick laminated glass, or the two sheets of glass 1 may be separated by an air layer. They may be bonded together to form a double-glazed glass.

The image is formed on the rough surface 1a, that is, the writing surface. By writing characters and patterns on this surface, it can be used very effectively while giving a new atmosphere to presentations at meetings etc. Is possible.

Since writing work can be performed with an image as a background, it has become possible to provide a new sheet glass that is extremely practical. In addition, the transparency and color of the glass material, and the decorative synergistic effect of the light emitting part, make it excellent in decorativeness and design in addition to practicality. This is a very significant invention that can broaden the adaptation range to the living environment.
