ABSTRACT:
A braille print board having a plurality of sets of six-dot holes for forming braille letters, a retaining sheet on one side of the print plate and a dot hole sheet on the other, the dot hole sheet and the retaining sheet having braille letters in the form of punctures in the dot hole sheet and depressions in the retaining sheet aligned with the holes and formed with a braille typewriter or braille pen, balls in the holes, through the punctures, and a cover sheet pasted over the dot hole sheet so as to prevent the balls from dropping out of the holes. In another embodiment, the balls are disposed in a ball supply plate between the print plate to which the retaining plate is fixed and a ball supply plate, and the braille pen or braille typewriter presses the balls from the holes in the ball supply plate into depressions formed thereby in the retaining plate.
