Abstract: A page size slate structure includes first and second plates hingedly mounted relative to one another permitting a face-to-face relationship in a continuous communication, with the first plate having a matrix of openings, and the second plate having a matrix of cells, each of said cells having six recesses arranged in a symmetrical pattern, with each of the recesses being positioned for reception within a relief gap in a side wall of the first plate openings permitting the imparting of braille patterns upon a sheet material secured between the first and second plates. A pointed object such as a conventional braille stylus is employed to effect projection of a marking onto the paper.
