Two proposed electromechanical systems for making braille characters produced relatively inexpensively. Similar in operating principle to dotmatrix printers, two methods use electronically actuated pins to reproduce characters from information stored on magnetic tape. First, one or more pins scanned over blank page and energized at intervals to emboss text on paper, one or more dots at time. Second, handheld device containing one or more character-generator cells used by reader to scan lines of text manually.
