ABSTRACT:
A braille printing apparatus utilizes non-impact printing technology to provide high-speed, high-volume production of printed braille materials. The document carrying the information to be printed in braille is scanned and read under the control of a computer. The computer outputs the object information in the form of control signals. In accordance with these control signals, a write head projects a beam of light to form a latent image on the charged surface of a rotating drum. Toner is used to develop the image and transfer it to paper, where it is fused. A coarse-grain toner is used, and is applied in a sufficient quantities thereby produce printed braille materials.
