Description

[Detailed description of the invention] The present invention relates to a Braille copying board.

When writing Braille using the conventional method, a Braille tool consisting of a Braille board, a ruler, and a dot pen, or a Braille typewriter are used to project the Braille paper from the front side to the back side and write horizontally from right to left.

To read this, you usually touch the convex surface with your index finger and read from left to right. Although the Braille typewriters and Braille printing presses have been available for some time, their high prices have prevented them from becoming widely available, and the current situation is that we still have to rely on handwritten manuscripts provided by Braille translators. . Braille is printed with a certain line spacing, and then printed from the back side between each line to print Braille characters on both sides of a sheet of paper.

For this reason, printing with the Braille board is time consuming because after printing on the front side is completed, the paper is turned over and new Braille characters are printed between the lines of Braille characters that have already been printed as described above. . 5 Furthermore, since printing methods using Braille boards did not leave any plates, increasing the number of copies published required more Braille translation work.

The present invention was invented in view of these current circumstances, and
A hole the size of the outside diameter of the protrusion of one Braille character is inserted into a plate of hard 10 plastic whose thickness is equal to the height of the convex part of one Braille character. Two braille boards with rows of braille holes formed therein are provided, and hard dot balls, which will become braille characters, are inserted into the holes of one of the braille boards and glued to the rows of braille holes. By attaching tape to fix the dot ball inserted into the Braille hole and protruding the dot ball to the opposite side of the adhesive tape, Braille characters can be printed efficiently and saved as a Braille plate. The purpose of this project is to provide a Braille copying board that is capable of printing.

Next, preferred embodiments of the present invention will be described with reference to the drawings.

Reference numeral 10 denotes a Braille plate made of hard plastic or the like, and has the same thickness as the height of the protrusion of one Braille point.

25 For Braille, the size of the dots and the spacing between letters are determined, so the Braille hole 11 is set to accommodate 6 dots as one character.
, 11 are disposed continuously in the lateral direction over the entire surface of the Braille board 10.

The braille plates 10 are used as a set of two, and it is convenient to overlap the braille plates 10, 3010 and connect and fix one side edge with the connecting cloth 12 to align the dot holes. It is not necessary to connect the two Braille boards, as it is sufficient to sandwich the Braille paper between them and securely secure them with clips or the like. 3515, 15 are hard dot balls inserted into the braille holes 11, 11, which are made of metal or hard plastic and have the same diameter as the inner diameter of the concave portion of the braille. After loading, adhesive tape 16 is attached to the Braille rows of the Braille board 10 to fix the dot balls, and approximately half of the dot balls protrude from the Braille board.

FIG. 3 shows an example of how to efficiently insert a dot ball into a braille hole.
0, the hard dot balls 15, 15 are inserted into the recesses 14 of the Braille characters on the back side of the Braille characters, and fixed with an adhesive tape 16.

Since Braille is engraved on the front and back sides of the Braille paper 13, after inserting the dot balls 15 into one Braille board 10, the dot balls 15,
Braille holes 11 between the rows of Braille lines in which Braille holes 15 are inserted,
11 is loaded with dot balls 15, 15, which are also covered with adhesive tape 16.
, 16, and remove the Braille base paper 13 from the Braille plates 10, 10. In this way, the two Braille plates 10, 10 have protrusions corresponding to the recesses of the Braille characters on the hard dot balls 15, 15.
Therefore, when a new Braille paper is sandwiched between the Braille plates 10, 10 and pressure is applied from the outside of the Braille plates 10, 10, the dot balls 15, 15 pass through the paper and open the opposing Braille holes 11, 10. 11, and Braille characters similar to those of the Braille base paper 13 are printed on both sides of the paper.

Note that the work of inserting the dot ball 15 into the braille hole 11 is
7, find the recesses 14 of the Braille base paper 13 and insert them one by one.
If the Braille plate is tilted after the dot balls are inserted into the Braille board 1, the dot balls 15 located on the flat part of the Braille base paper 13 will fall out of the Braille holes 11. By attaching the dot ball 15 to the dot hole, it becomes possible to reliably insert the dot ball 15 into the dot hole.

As explained above, the present invention involves forming hard dot balls into Braille characters and inserting them into a Braille board provided with a row of Braille holes in which each character has six dot holes that correspond to the eyes of Braille characters, and then gluing the dot balls. Since it is fixed with tape, by using two Braille boards and applying pressure by sandwiching paper between the Braille boards, it is possible to create Braille books in succession and also to save them as originals. There is.

Furthermore, if there is no need to preserve it as a Braille printing original plate, the adhesive tape can be removed and all the materials can be reused, making it economically effective.

[Brief explanation of drawings]

Fig. 1 is a partially cutaway plan view of the Braille copying plate of the present invention, Fig. 2 is a partially enlarged plan view showing the inner surface of the Braille plate, and Fig. 3 is taken along line 3-3 in Fig. 1. In the cross-sectional views, A is a state where the Braille base paper is sandwiched between two Braille boards, B is a state where the Braille board and Braille base paper are overlapped and a dot ball is inserted into the recessed part of the Braille through the Braille hole, and C is a state where the Braille base paper is inserted into the recessed part of the Braille character through the Braille hole. After being inserted into the braille hole, it is shown fixed with adhesive tape.

Claims (1)

[Claims] 1. Holes the size of the outside diameter of the convex part of one Braille character are made in a board made of hard plastic, etc. whose thickness is the height of the convex part of one Braille character, and six consecutive holes corresponding to the eyes of the Braille character are used as one character. Two braille boards with rows of braille holes formed therein are provided, hard dot balls that will become braille characters are inserted into the braille holes of one of the braille boards, and adhesive tape is applied to the rows of braille holes.
