Description

[Detailed description of the invention] The present invention relates to a Braille printing plate.

When printing Braille using the conventional method, use a Braille device consisting of a dot hole plate, a ruler, and a dot pen, or a Braille typewriter to form convex portions on the Braille paper from the front side to the back side, and then print from right to left. Write horizontally. To read this, touch the convex part with your index finger and read from left to right. Braille typewriters and Braille printing presses have been available for some time, but 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.

After printing Braille with a certain line spacing,
Braille characters are printed on both sides of a sheet of paper by printing from the back side between each line. For this reason, printing using a perforated plate is time-consuming because after printing on the front surface is completed, the paper is turned over and new Braille characters are printed between the lines of Braille characters that have already been printed.

In addition, printing methods that use perforated plates do not leave any plates, so increasing the number of copies published requires a lot of braille translation work.

The inventor of the present application proposed a Braille printing plate that improved these conventional techniques in Japanese Patent Application Laid-Open No. 57-43894 and Utility Model Application Publication No. 58-48436. Although the workability of these Braille printing plates is improved compared to the conventional method, there remains some dissatisfaction among the Braille translators, although this is not a problem.

In the prior art, a continuous row of braille holes is formed on a plastic dot hole plate having the same thickness as the height of the convex part of one braille point, with six dot holes corresponding to the eyes of a braille character as one character. Adhesive tape was pasted on the rows, and dot balls were attached to each of the six dot holes in the row of braille holes so as to form braille characters.

By the way, the method of attaching dot balls to a dot hole plate is to attach dot balls to all the dot holes and then remove the dot balls that are unnecessary for Braille characters. On the other hand, to remove dot balls from the dot hole board, a nail-like object (often using a dot pen) was used to remove dot balls from the dot hole board, but the work of removing dot balls is not easy. There was found. As mentioned above, the creation of Braille is often done manually by Braille translators, so good workability is a condition for the spread of Braille and the increase in the number of Braille translators.

The purpose of the present invention is to further improve the Braille printing plate previously proposed by the inventor of the present invention, and to provide a Braille printing plate that can print Braille characters efficiently and that can be stored as an original plate for a long period of time. A printed version is provided.

In order to achieve the above object, the present invention provides six dot holes for forming Braille characters on a dot hole plate made of hard plastic or the like.
Braille holes to be used as characters are continuously punched, a vinyl chloride sheet is pasted on one side, and dot-hole paper coated with an adhesive that remains on the paper when peeled off is pasted on the other side. It is characterized in that the dot balls are press-fitted from the dot hole paper side, the vinyl chloride sheet is made to protrude from the dot hole plate, and a plastic sheet is polymerized and pasted on the top surface of the dot hole paper.

Next, details of the present invention will be explained with reference to illustrated embodiments.

The point hole plate 10 is made of hard plastic and has six points in one
Braille holes 11, 11 serving as characters are provided consecutively in the horizontal direction, and a predetermined number of lines are arranged. or,
A vinyl chloride sheet 12 is placed on the surface of the hole plate 10.
A perforated paper 13 coated with an adhesive that leaves the adhesive on the paper side when peeled off is attached to the back side.

The dot hole plate 10 has dot holes 14, 14 forming the Braille characters facing the dot holes 11, 11 with the dot hole paper 13 facing upward (FIG. 3A). Since completed Braille is read from the left, the dot holes 14, 14 are drilled from right to left using a Braille typewriter or pen. Since the braille typewriter has standardized braille positions, the dot holes 11, 11 of the dot hole plate 10 are
If it is formed according to the standard, it can be stamped directly onto the perforated paper 13 using a typewriter. On the other hand, since a dot pen is a nail-shaped pen with a rounded tip, another dot hole plate 10 is placed on the bottom surface of the dot hole plate 10.
overlap and match the position of the braille hole 11,
Dot holes 14, 14 are made using the braille holes 11 of the overlapped dot hole plate 10 as guides.

Dot holes 14 that serve as Braille characters in all rows of the dot hole plate 10,
After the drilling work of No. 14 is completed, the point holes 14, 14 are
The dot balls 15, 15 are attached inside (Fig. 3B). When the point holes 14, 14 are formed, the point hole plate 10 is placed in a container with a frame (not shown), and a large number of point balls 15, 15 are placed in the container and the entire container is tilted. 15, 15 can be quickly installed in the point holes 14, 14. The point balls 15, 15 described above are made of metal, which is most superior in terms of handling and economy.

Next, the dot balls 15, 15 are pushed out toward the PVC sheet 12 by applying pressure to the dot balls charging surface.
5 is stabilized (FIG. 3C), and then a plastic sheet 16 is polymerized and pasted onto the perforated paper 13, which has become flat, to form a printing original plate 17 (FIG. 3D).

With the above, the original printing plate 17 is completed, and the dot ball 15,1
Since the protruding surface of 5 has Braille characters, if you touch the protruding part in this state, you can read it as Braille. Incidentally, when proofreading is necessary, the PVC sheet 12 on the dot ball protruding surface is peeled off, the dot ball 15 is attached and removed, and the characters are corrected. Also, when calibrating before loading the dot balls, the dot paper 13 with the dot holes 14 is corrected from the back side to prevent dot balls from entering. You can re-perforate the correct characters.

As mentioned above, in Braille printing, Braille characters are formed on the front and back sides every other line, so when printing both the front and back sides of a sheet of paper at the same time, two original printing plates 17 and 17 are used as a set as shown in Figure 4. The edges are connected by a connecting cloth 18 to form a two-page spread, so that the printing original plates 17, 17 can be freely overlapped and folded, and each dot-perforated plate 10, 10 has a hole in every other row. A charging row for point balls 15, 15 is configured.

Original printing plate 17, 17 completed in this way
When a Braille paper is sandwiched between them and pressure is applied from the outside with a roller, the dot balls 1 protrude from the dot hole plates 10, 10.
5 and 15, the hemispherical protrusions are transferred onto the Braille paper, and Braille printing is simultaneously performed on the front and back sides of the paper.

Also, if a new perforated plate with a PVC sheet and perforated paper pasted on the lower surface of the original printing plate 17 is superposed and pressurized,
The new dot plate has a recess for loading dot balls, making it easy to copy the original.

After printing is completed, the PVC sheet and dot paper are removed and the dot balls are collected. The dot plate remains, and the dot board and dot balls can be used again. Therefore, the cost of the printing plate is very low. become.

According to the inventor's experimental results, the thickness of the hole plate
0.5 mm, the thickness of the PVC sheet and dot paper that are directly attached to the dot hole plate are each 0.1 mm, and the dot ball diameter is 1.2 mm, so the height of the peak that protrudes from the dot hole plate and becomes Braille letters is 0.6 mm. mm, and when transferred from this original plate to Braille paper, the Braille crest was 0.5 mm or more, and easy-to-read Braille characters were obtained.
