Abstract

This disclosure provides a process which permits the copying of braille documents and the creation of braille copies from flat documents. Embossed marks on paper are not readily copied, and in particular a standard photocopier is useless to a blind braille reader. The following process produces braille copies. 1. Darken the raised braille marks on the document such as by rubbing with a sheet of carbon paper. 2. Produce a sheet of plastic with the dark areas thereon such as a conventional foil. 3. Support the plastic sheet on an open grid and heat it such as with an infrared lamp so that the darkened areas absorb heat. 4.

Braille Photocopier

This disclosure provides a process which permits the copying of braille documents and the creation of braille copies from flat documents. Embossed marks on paper are not readily copied, and in particular a standard photocopier is useless to a blind braille reader. The following process produces braille copies. 1. Darken the raised braille marks on the document such as by rubbing with a sheet of carbon paper. 2. Produce a sheet of plastic with the dark areas thereon such as a conventional foil. 3. Support the plastic sheet on an open grid and heat it such as with an infrared lamp so that the darkened areas

absorb heat. 4. Apply pressure to the softened plastic (for example,

by jets of air) so that the plastic becomes deformed in

those darkened areas which correspond to the braille

characters and the plastic is bulged through the grid at

those points. 5. Cool the resultant braille copy so that the raised

areas remain fixed. The resultant braille copy can then be cleansed of the darkening material and is ready for use by a visually handicapped person.
