This standard does not imply the adoption of the USA Standard X3.17-i966 as the DOD standard font for OCR but intends to illustrate an OCR keyboard; that is, the DOD may standardize a different font design but in all practicality the
13、 individual characters of the set would be the same. These keyboard arrangements were developed from a study of keyboards aiready in use by millions of trained operators in the teleprinter, typewriter and related fields. (USAS X 4.7-1966) and the applicable international standards work also were inc
14、luded in the study. In addition, careful consideration was given to the military requirements for low initial cost, low maintenance cost, minimutn space (or size) utilized for each functional equipment (particularly in tactical situations), and the military environment wherein OCR and non-OCR operat
15、ions are Co-located and operators inter- changed.
