Abstract
Ideographic typewriter and method in which a set of characters are printed on a keyboard panel in optically readable form and scanned to provide a bit map of a character which is to be printed. A printer is actuated in accordance with the bit map to form an image of the selected character on an output medium. Characters beyond those included in the set printed on the keyboard panel can be written on a calligraphy pad near the keyboard and scanned to provide bit maps for use in the printing of those characters. Information associated with the characters is prerecorded in tracks on a magnetic medium positioned beneath the keyboard panel and transduced in a manner which substantially eliminates crosstalk between the tracks.
