BRAILLE MODULE COMPRISING OUPUT-PIN EXTRUDED BY THERMAL EXPANDING FLUID

摘要

A Braille output module having an output pin protruded by a working fluid which thermally expands is provided to protrude the output pin corresponding to the dot of Braille to an opening by using the working fluid which thermally expands, thereby recognizing the Braille easily. A housing comprises a housing and a base(160). The housing is arranged in an upper end. In the housing, a plurality of openings(111) is equipped. The base is arranged in a lower end. A guide unit(120) comprises a plurality of guide through holes(121) forming a concentric respectively with a plurality of openings. An output pin(130) is respectively inserted into the plurality of guide through holes. A plurality of thermal expansion units(140) is respectively arranged in the lower part of the output pin. The plurality of thermal expansion parts comprises a working fluid protruding the output pin in an opening direction in the thermal expansion.
