摘要

In an embodiment, a direct-braille-slate(300;500) includes a slate-base(302;502), a slate-frame(306), and a line-guide-unit(334). The slate-base(302;502) includes rows(324a), each row includes cells(332), each cell includes fixed number of protruded pins(331) to create embossed bump impressions on braille-paper(326) when pressed using stylus(316). The slate-frame(306) is hingedly coupled with slate-base(302;502) on one end, and open at other end for inserting braille-paper(326) in between slate-frame(306) and slate-base(302;502). A line-guide-unit(334) includes line-guides(400), each line guide hingedly coupled with an edge portion(321) of slate-frame(306) to move between a closed position and a flipped-open position. Each line-guide(400) includes an elongated body(402) including grooved cell-guides(404) aligned over cells(332) of a row of rows(324a) in closed position for creating embossed impressions on the braille-paper(326), and the row is accessible for reading embossed impressions in flipped-open position. Each line-guide(400) is braille-numbered(338) and has plurality of embossed marking(406) at a fixed interval to locate row-column of braille-cells on the braille-paper(326).
