Description of the Related Art Conventionally, in the Braille system in which Braille is displayed by operating a Braille pin, as shown in Fig. A braille display system consisting of 4 is known. A braille pin 4 is installed in the holding solenoid 3 facing downwards, and is configured to supply a set current or a reset current to the solenoid 3. By flowing, the Braille pin is moved up and down via the spring 5.

れる。In FIG. 1, all three Braille pins 16 are in a reset state (a state in which the pins do not protrude from the display surface) using a solenoid 15 and a spring 17. After the Braille pins are reset as described above, the belt is moved by driving the belt winding mechanism 21 shown in FIG. 2, and the display belt 13 having all the predetermined display patterns is set in a predetermined position. do. Next, by turning off the excitation of the solenoid 15, all the Braille pins are moved upward by the restoring force of the spring.
At this time, if a hole is made in the display belt 13 at the corresponding position (hole 11b), the m braille pin will be inserted into the hole 11 on the display surface.
If there is no hole, the upward movement will be stopped on the back side of the belt 13 during the display.
