Embodiment Construction

[0020] best practice

[0021] figure 1 is a schematic front view of a touch bar display device 100 according to an embodiment of the present invention, and figure 2 is a schematic plan view of the touch stick display device 100 . The touch stick display device 100 is capable of displaying 4 digits of Braille, and is composed of eight touch stick display units 200 (using two touch sticks 20A, 20B) arranged in a line with a predetermined gap as described below. Thus, a first column of eight touch bars 20A and a second column of eight touch bars 20B are formed. The suffixes A and B are added to the elements attached by the first touch bar 20A and the second touch bar 20B, respectively, although these suffixes are not added to the elements common to the first column and the second column. figure 1 It is a front view of the touch bar units 200 arranged in a row seen from the side of the first row.

[0022] refer to figure 1 and figure 2 , reference numeral 20A ( 20B ) de...

Abstract

A touch pin display device comprises a touch pin (20) for displaying a raised letter, a support housing (30) supporting the touch pin (20) movably, a cam (40) allowing the leading end of the touch pin (20) to protrude from a touch surface (35) to a desired height (an ON state), a compression coil spring (10) biasing the touch pin (20) to the cam (40), shape-memory wire (60) which is heated by energization to allow the cam (40) to be rotated forward so that the touch pin (20) is set to be in the ON state, and a cam reciprocating board (50) which allows the cam (40) to be rotated backward so that the touch pin (20) is retreated to the level of the touch surface (35) (an OFF state). The touch pin (20) is not retreated since the upper surface of the cam (40) supports the lower surface of the touch pin (20) even in the case where a user strongly presses the touch pin (20) or energization to the shape-memory wire (60) is cut in the ON state. Every touch pin (20) can be returned to the OFF state by one reciprocating motion of the cam reciprocating board (50).

Description

technical field [0001] The present invention relates to a Braille numeral used to display a generally hemispherical projection (or tactile bar) formed by a plurality of dots (for example, 4 dots), or a number formed by a plurality of dots (for example, 6 dots or 8 dots). Any Braille character formed by a roughly hemispherical projection (or tactile stick) of a dot), or a tactile stick display device for any Braille graphic. More specifically, the present invention relates to a tactile stick display device that uses a cam and shape memory wire to raise the end of the tactile stick to a desired height ("ON" state) from the tactile surface. Background technique [0002] A conventional touch stick (Braille) display device arranges a predetermined number of Braille display members (Braille display units) that electromechanically improve The ends of the multiple touch rods (Braille pins) shown. The visually impaired person slides a finger over this line to touch (read), thereby ...
