Method of and apparatus for reading characters formed by a plurality of areas

摘要: The invention provides a method of and apparatus for reading characters formed by plurality areas, or perforations equal size arranged at intersections the rows columns notional matrix. number arrangement areas to form character is chosen so that only three forming need be scanned, each row having one, two four uniquely identify character. Each scanned photosensitive device which produces, signal whose magnitude proportional total in row. coded position binary code provide representation first third positions are assigned values derived from scanning second fourth value produced on rows. If maximum occurs row, assumes ''1'' while value''0.
