Abstract
Apparatus for making tactile impressions, such as a Braille matrix, on paper. The apparatus includes a paper receiver, pins, a driver, and a rotating print wheel. The receiver accepts paper, and the driver selectively extends pins toward the paper. The print wheel rolls over the pins, pressing the paper and pins in close contact. Consequently, the pins leave a tactile impression on the paper.
