PURPOSE:To enable dot pin spacing to be reduced and enable Brailles conforming to practical use to be displayed, by providing a belt having a desired display patterns between a display surface and dot pins. CONSTITUTION:The display belt 13 is provided between the display surface 12 having pin-projecting holes 11a and the dot pins 16 driven by a solenoid 15. The diameter of the holes provided in the belt 13 and the display surface 12 is preferably about 2mm., and the diameter of the dot pins is preferably about 1mm.. The spacing between the dot pins can be reduced to 3-4.5mm., since a plurality of dot pins can be operated by a single solenoid. |
