Claims

[Claims for Utility Model Registration] (1) A plurality of piezoelectric element pieces that are curved by applying an electric signal, and a plate surface so that these piezoelectric element pieces can be stacked and mounted at a predetermined interval. a base member having a groove formed therein; a fulcrum member provided within the groove of the base body and supporting a substantially central portion of each of the piezoelectric element pieces with a degree of freedom in curvature displacement;
Fixing means for fixing the base end of the piezoelectric element piece;
A Braille cell characterized by comprising a tactile pin provided at the free end of the piezoelectric element piece and having tips aligned at the same height. (2) Utility model registration claim 1, characterized in that the base body has a printed circuit board integrally provided on the base end side of the piezoelectric element piece, and the base end of the piezoelectric element piece is fixed to the printed circuit board. Braille cell described in section. (3) Utility model registration claims 1 to 2, characterized in that the base body has a fitting part on one side and a hole corresponding to the fitting part on the other side for connection when installed side by side. Braille cells listed in any of the sections. (4) The braille cell according to claim 1, wherein the fulcrum member is formed in a U-shape and has opposing inner surfaces projecting in a curved manner. (5) The tactile pin is held movably according to the curved displacement of the piezoelectric element piece, and is characterized in that a tactile scanning part having a hole from which only the tip of the tactile pin can protrude is integrally formed on the base body. A braille cell according to claim 1 of the utility model registration claim. (6) Utility model registration claim 1, characterized in that a piezoelectric element piece is floated on the plate surface within the groove to form a line-shaped friction reducing portion that reduces frictional resistance.
Braille cell described in section.
