Description

[Detailed description of the invention] This invention relates to a Braille printer.

Conventional Braille books use a Braille machine consisting of a Braille board, a ruler, and a dot pen to place a piece of Braille paper on a Braille board arranged in parallel so that many concave dots fit into the squares of each line, and then place the Braille paper on top of the Braille board, which is arranged in parallel so that many concave dots fit into the squares of each line. In addition to writing (engraving) by applying a ruler with a square (hole) corresponding to the dot and pressing the concave dot from within the square with the tip of a dot pen, there was also a method of writing (engraving) with a Braille type stamp or a convex dot. They were made using methods such as mechanical printing on original plates.

However, since Braille boards and Braille types are manufactured in one piece, it is not possible to make many items at once, and the disadvantage is that making many items requires a lot of manpower and time. Mechanical printing is also very expensive unless you are printing a considerable amount due to the production of Braille master plates or the cost of printing machine equipment, and the printing machines themselves are not widely available and are not easy to use. It was extremely inconvenient to create multiple Braille books.

The present invention seeks to address these problems by providing a low-cost, easy-to-operate Braille printer, and the embodiments shown in the drawings will be described in detail below.

FIG. 1 is a perspective view showing an embodiment in which the Braille printing device of the present invention is applied to a hand-printing type printing device that can be used both front and back. A frame plate 12 and a braille plate 13 are formed into the same rectangular shape and overlapped with each other, and a hinge 1 is attached at each side edge so as to overlap and cover the outer surfaces of the frame plate 12 and braille plate 13.
Covers 16 and 17 are rotatably (opened and closed) connected to each other at 4 and 15 to form a main body of the printing press, and a roller-shaped pressing tool that is pressed against and rolled on the surface of the frame plate 12. It is equipped with 18.

FIG. 2 is a partially enlarged sectional view showing the printing state of this printer. A thin plate-shaped scale 21 made of hard plastic material or the like is fixed to the surface of the frame plate 12, and the scale 21 has 32 characters (32 characters) horizontally attached to it. square), 16 vertically
Square-shaped scale holes 22 arranged according to the standards of row Braille books are bored, and the scale holes 2
2, there are three dot holes 23 vertically and two rows laterally drilled through the frame plate 12 according to the squares.

Inside each scale hole 22, there is a pin-shaped dot whose head is shaped like a nail or rivet and whose tip is rounded so as to display predetermined Braille characters on the back side. A predetermined number of brushes 25 are inserted in a predetermined arrangement. The dot pen 25 is fitted in the dot hole 23 to such an extent that it can be moved up and down by its own weight, but a recess 26 of a certain depth is formed on the back surface of the cover 16 at a portion corresponding to the scale hole 22. Since the cover 16 is folded over the scale 21,
The dot pen 25 falls and moves by approximately the depth of the recess 26 even when the main body of the printer is turned upside down. Reference numeral 27 denotes fixing devices such as velvet fasteners attached to corresponding positions of the cover 16 and the frame plate 12, and are used to detachably set the cover 16 and the frame plate 12 when the cover 16 is folded and stacked on the frame plate 12. .

The overlapping surface of the braille board 13 foldably overlapped with the back surface of the frame board 12 forms a concave dot pattern 29;
There is a concave dot 2 at a position corresponding to the square of the scale hole 22, that is, the dot hole 23 bored inside the scale hole 22.
8 is formed. Therefore, the recessed surface 29
When the Braille paper 30 is inserted between the back surfaces of the frame plate 12 and the frame plate 12 is placed on top of it, the cover 16 is opened, and the pressure tool 18 is rolled and pressed on the scale 21, the Braille paper 30 protrudes from the top surface of the scale 21. The dot pen is pushed into the deepest part, and a predetermined Braille character is printed on the Braille paper 30 by the tip of the dot pen 25 and the recessed point 28. Once a predetermined Braille character is set in the dot hole 23 in each scale hole 22 of the scale 21 by such an operation, many copies of the same Braille book can be made by sequentially replacing the Braille paper 30.

In order to accurately place the Braille paper on the recessed surface 29, an appropriate number of abutments 31 made of suitable protrusions etc. are provided at predetermined positions on the outer periphery of the surface of the Braille plate 13, and roller-like pressure A grip 33 is rotatably fitted to a shaft 32 protruding from both ends of the tool 18 so that it can be easily pressed and rolled manually.

Note that the illustrated embodiment has a structure in which printing is performed on the front and back sides in one set of Braille paper, but for this reason, it is possible to print Braille from the back side of the Braille paper 30 by focusing on the holding surface of the Braille paper 30. The structure is almost symmetrical on both sides. That is, as shown in FIG. 2, the covers 16 and 17, the frame plate 12, and the Braille plate 13, including the attached parts, are almost vertically symmetrical structurally, and the back side of the frame plate 12 is printed on the back side. A recessed point 28 is sometimes provided to function as a recessed point surface, and the braille board 13 also has a scale 21, a dot hole 23, and a dot 25.
are provided in exactly the same way as in the case of the frame plate 12.

However, the front and back sides of the Braille paper 30 have different written contents, and if the printing positions overlap, the printing on the two sides will be mixed up and become illegible, so the incorporation of each Braille character and the position of each line of Braille characters are different. There is. That is, the position of each line of Braille is such that the scale hole 22, the dot hole 23, and the concave dot 28 are located between each line so that printing on the back side is performed with a predetermined line spacing between the lines printed on the front side. It is configured as follows.

In the above example configured in this way, the Braille characters on the front and back sides are arranged in a predetermined combination of characters, and after the Braille paper 30 is sandwiched, the front side is first printed, and then the printer body is turned over and the back side is printed. Print. At this time, while printing on one side, the dots related to printing on the other side slip out downward due to their own weight, but are caught by the recess 26 in the lower cover 16 or 17. It won't fall off.

In addition, in the above embodiment, the frame board 12 and the Braille board 1
Although only each scale 21 of No. 3 is fixed as a separate member, it may be integrally molded with the frame plate 12 and the Braille plate 13, or it may be made of multiple pieces in which certain parts are separately processed for processing convenience. It may also be made by stacking thin plates of The material for each part can be selected arbitrarily depending on its function, such as metal, synthetic resin, or wood, but it is desirable to use as lightweight a material as possible from the viewpoint of the intended use.

Further, the pressing tool 18 does not necessarily have to be roller-shaped, and it is sufficient if it can push the head of the pointer 25 protruding onto a plane. Further, the present invention can also be applied to mechanical Braille printing machines by applying its principles.

As a result of this invention having the above-described structure, it is possible to easily and inexpensively reproduce a large number of books compared to handwriting or Braille type, which is one of the conventional methods of creating Braille books, and it is possible to reproduce a large number of books using a mechanical printing machine. In addition to being cheaper than other books, it can be easily printed by the general public, and is especially suitable for making copies for distribution to a relatively small number of people. The basic principle of the present invention can also be applied as a part of a mechanical printing machine, and in this case, it is sufficient to incorporate the Braille characters into the frame plate, which is significantly more economical than the case where a concave-convex original board for Braille characters is made for each page. .
