PURPOSE:To restore a Braille sheet to a state before recording by way of easily erasing a recorded Braille by using the Braille sheet made from shape memory resin. CONSTITUTION:A Braille sheet 100 formed in a loop is made from shape memory resin on a part or the whole of its material, and it is delivered in the arrow direction by a heating roller 200, a driving roller 210 or a roller 220. Information from a CRT screen 410 is transmitted to a letter-diagram/Braille conversion device 400 through a cord 510, and after it is converted to Braille printing information, it is sent to a Braille printing device 300 through a cord 500. The Braille printing device 300 prints an input Braille or diagram on the Braille sheet in a temperature region of lower than glass transition temperature Information 120 printed on the Braille sheet 100, after it is presented to a user for deciphering by a display part 110, is heated to be higher than the glass transition temperature by the heating roller 200 and is restored to an original state. |
