Abstract
A braille cell assembly is described which provides precision cell positioning. Such assembly includes a holder in the form of a tray which engages the individual braille cells, which holder is selected to be capable of itself rigidly maintaining the individual cells in predetermined positions adjacent to one another. The position of each cell in the assembly is thus independent of other cells of the assembly.
Claims6
In a braille cell assembly, the combination comprising:
- (a) a plurality of individual braille cells;
- (b) a holder engaging said braille cells, which holder is selected to be capable of itself rigidly maintaining each of said individual cells in a predetermined position adjacent other cells without relying for positioning on such other cells;
- and
- (c) interlocking structure on said cells and said holder for maintaining said cells in said predetermined positions, said interlocking structure including a flange on said holder, and each of said cells includes a support frame defining a slot which is complementary to said flange and engageable therewith.
