摘要: An optical character recognition system utilizes a reflecting data card including one or more fonts for the entry of plurality optically recognizable characters. The also includes non-reflecting timing marks indicating position these fonts. Conventional means are used passing cards at predetermined speed past an array columns comparators and light source adapted to shine into so that it will reflect onto array. Each comparator is produce voltage pulse in response drop intensity reflected light. In addition, provided detecting thereby triggering sources.
