Abstract
A method and apparatus whereby information appearing on a CRT screen (410) is separately displayed in braille, using a braille web (100) in a loop form and made partly or wholly from a shape memory resin. The information from a CRT screen (410) is input to the web (100) by a braille printer (300) at a temperature within a range below the glass transition temperature of the resin. After the information has been read by the user, the displayed web portion is heated above the glass transition temperature by a heating roller (200) so that the web recovers its original, non-braille shape. The web is conveyed by a driving roller (210) along with the heating roller (200) and a driven roller (220) in the directions indicated by arrows in FIG. 1 for repeated use.
