Abstract:
A display device comprising:a pin matrix having a plurality of parallel bores for supporting a plurality of pins mounted to slide within said bores; a plurality of pins each said pin associated with and within and slidably translatable within said plurality of bores; a reset surface toward which said pin matrix can be approachably moved to align an axial depth of said plurality of pins with respect to said pin matrix; a moveable belt having protruding symbols, and said pin matrix also translatable to engage a subset of said plurality of pins to contact at least one of said protruding symbols to enable subset of said plurality of pins to become axially displaced in congruence with said protruding symbol; mechanical means for moving said pin matrix in order to periodically re-align said plurality of pins and to periodically engaged said subset of said plurality of pins against said at least one of said protruding symbols; mechanical means for driving said moveable belt to change a position of said at least one of said protruding symbols, in order to enable expression of said at least one of said protruding symbols upon said periodic re-aligning of said plurality of pins and periodic engagement of a differently located subset of said plurality of pins against said at least one of said protruding symbols.
