  In this conventional braille device, since the user cannot use the braille unless he / she knows it, the schoolchild must first learn braille. However, studying Braille with limited class hours is extremely difficult, and it was impossible to communicate between schoolchildren and visually impaired people by creating Braille.

  The problem to be solved by the present invention is that when a schoolchild creates a sentence such as a letter in Braille, even if he / she does not learn Braille, he / she can easily write a letter, etc. in Braille, or change the sentence in ink to a sentence in Braille It is to provide a Braille device that can perform so-called Braille translation.

In order to achieve the above object, a Braille device according to the present invention includes a pressing body, a plurality of band-shaped dials, and a printing board that sandwiches a sheet. the slidable insertion to the transverse bore, the pin-receiving portion provided at the lower end, the pressing body provided six lift pins each lifting freely is supported on the pin receiving portion, and its lower end by a coil spring Protruding from the pin receiving part , facing the lower surface of the dial inserted in the horizontal hole, and matching the character alignment position provided in the horizontal hole of the pressing body on the upper surface of the dial , such as hiragana, numbers, etc. The ink characters are sequentially displayed in the longitudinal direction, and the lower surface is sequentially arranged in the longitudinal direction so that the recess corresponding to the ink characters aligned with the character alignment position is located above the lifting pins. configured to use the lift pin rises, the printing plate The board includes a board and a ruler plate overlaid on the upper surface, and the board is provided with a large number of Braille recesses having 6 blocks, and the ruler plate has a pin receiving portion of the pressing body at a corresponding position of each Braille recess. A guide hole is formed.

Braille device of the present invention, sandwiched Turn the paper postcard or the like between the printing plate substrate and ruler plate, insert a dial next hole of the pressing body, attempts to inscription appears on the upper surface After aligning the ink character with the character alignment position of the pressing body , if the pin receiving portion provided at the lower end of the pressing body is inserted into the guide hole provided in the ruler plate of the printing board and the pressing body is pushed down, The upper ends of the unnecessary lifting pins are press-fitted into a recess provided on the lower surface of the dial, and the upper ends of the other lifting pins are held on the lower surface of the dial. As a result, the lower end of the elevating pin that is held at the upper end and prevented from rising presses the paper into the Braille recesses of the substrate in a dotted manner, and a predetermined Braille is displayed.

Next, slide the dial or replace it with another dial to align the desired ink character with the character alignment position , then insert the pin receiving part of the pressing body into the guide hole of the printing board and push the pressing body down For example, braille characters such as hiragana are sequentially displayed on the paper.

  Since the Braille device according to the present invention is engraved while looking directly at the dial, it is possible to write a letter or the like in Braille without learning Braille. Moreover, since one character of Braille is engraved at a time by six lifting pins, it is possible to efficiently create a sentence in Braille. Therefore, it is very convenient when schoolchildren make letters addressed to visually impaired persons in welfare education classes or translate them into Braille.

  A detailed description will be given of a Braille device that can represent Braille text without learning Braille.
