  • Patent number: 4600320
    Abstract: A printer for producing both standard printed characters and braille characters on a recording medium comprising a platen having a cylindrical exterior recording medium surface, a braille embossing mechanism on the inside of the platen and the surface of the platen having solid and perforated regions so that on rotation of the platen the solid regions serve as a backing for standard printed characters and the perforated regions comprise holes in a 6 dot braille pattern, thereby providing for the simultaneous printing or typing of printed words and braille words. The braille characters are embossed directly below the printed characters in a one to one fashion which permits the typed correspondence to be read by the sighted and the braille embossing to be read by the blind simultaneously thereby saving time, effort and money for communicating with the blind and the sighted in the fields of entertainment, education and employment.
