  This conventional braille device cannot be used unless the user knows the braille, so 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 letter, etc. in braille, even if he / she does not learn braille, he / she can easily write a letter, etc. in braille, or change the text in ink to 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 dial, and a printing board. A horizontal hole that penetrates the dial is formed in an intermediate portion of the pressing body, and a lower end is formed. A pin receiving portion is provided, and six elevating pins are provided in the pressing body so as to be movable up and down, and the lower ends of the elevating pins are pins so as to maintain a protruding state from the pin receiving portion when the pressing body is depressed. The upper part of each lifting pin faces the lower surface of the horizontal hole, and the upper surface of the dial sequentially displays hiragana, numbers, etc. in the longitudinal direction, and the lower surface corresponds to the above-mentioned ink character A concave portion that allows any lifting pin to be raised when the pressing body is pressed down, and the printing board is composed of a substrate and a ruler plate overlaid on the upper surface. A large number of Braille recesses are provided, each of which is a block. In position, it is characterized in that bored pin receiving portion of the guide hole of the pressing body.

  The braille device according to the present invention is a method of placing a letter such as a postcard between a printing board substrate and a ruler board, inserting a dial into a horizontal hole of the pressing body, and printing the ink mark to be engraved displayed on the upper surface thereof. After aligning with the predetermined position of the pressing body, if the pin receiving portion provided at the lower end of the dial is inserted into the guide hole provided in the ruler plate of the printing board and the pressing body is pushed down, a part of the six is pressed. The upper end of the lifting pins is 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 concave portion of the substrate in a dotted manner, and a predetermined Braille character is displayed.

  Next, slide the dial, align the desired ink letters to the specified position, and then insert the protrusion on the press board into the guide hole on the printing board and push down the press to display hiragana on the paper in sequence. It is done.

  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 people 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.

The pin receiving portion 5 has a thickness that fits into a guide hole of the printing board 3 to be described later, and is accurately fitted into the guide hole so that the lower end of the elevating pin 7 matches the Braille recess. In addition, inclined surfaces a are formed at the corners.

  The dial 2 is composed of a plurality of pieces, and the hiragana ink characters 12 are sequentially written horizontally at regular intervals on the upper surface, and a scale 13 is displayed between the ink characters 12. Concave portions 14 corresponding to the ink characters 12 are sequentially formed on the lower surface. As shown in FIG. 3, when a desired ink letter 12 is matched with one side of the pressing body 1, the recess 14 corresponding to the ink letter 12 is formed so as to match the position of the elevating pin 7. The recess 14 allows the elevating pins 7 not to be engraved to rise, and the lower surface of the dial 2 without the recess 14 prevents the elevating pins 7 from elevating. In addition, a notch 15 is formed on one side edge of the dial 2 in the longitudinal direction in accordance with the pitch between the ink characters 12 and the recesses 14 so that the desired ink characters 12 are located on one side of the pressing body 1 and the scale 13 When it is coincident with one side of the pressing body 1, it is configured to be fitted to a retractable ball 16 protruding into the lateral hole 6.
