Abstract:
Provided are a braille actuator and a braille outputting device using the same. The braille actuator includes an electromagnet, a rotation member, and a braille protrusion. With this configuration, the actuator applies a current to the electromagnet to allow the electromagnet to exert a repulsive force or attractive force on the permanent magnet of the rotation member, so that the rotation member is rotated, and due to the rotation of the rotation member, the upper surface of the rotation member allows the lower surface of the braille protrusion to be moved upward, and the braille protrusion is protruded. After that, even though the supplying of the current to the electromagnet is blocked, the braille protrusion is supported by the rotation member, and thus, the output state is maintained, so that it is possible to greatly reduce power consumption for output of braille.
