The work of developing International Standards is carried out through IS0 technical co

10、mmittees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards ad

11、opted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 2033 was developed by Technical Committee ISO/TC 97, Information processing systems, and was circulated to the member b

14、 ResaleNo reproduction or networking permitted without license from IHS-,-,-INTERNATIONAL STANDARD IS0 2033-1983 (E) Information processing - Coding of machine readable characters (MICR and OCR) 1 Scope This International Standard defines the coded representation of printed characters recognized by

15、reading equipment. It in- cludes the fonts: E13B CMC 7 OCR-A OCR-B as covered in IS0 1004 as covered in IS0 1004 as covered in IS0 1073/l as covered in IS0 1073/2 2 Field of application This International Standard assigns bit-patterns to characters recognized by reading equipment. This coded informa

16、tion generated by the reading equipment is given to the recipient by different media, such as magnetic tape, by data transmission or a direct link. This coded representation can also be used by printing devices to print the information which shall later be read. It is not intended for general inform

17、ation interchange. Two different applications are considered : - Single-font reader: The reading equipment is only capable of recognizing one font at a time. - Multiple-font reader: The reading equipment is capable of recognizing mul- tiple fonts at the same time. 3 References IS0 646, Information p

26、n every line will form one record; - if the information is handled character-by-character (data stream), the end of a line will be coded by means of control characters CR and LF. 5.2 Characters in error If a character is recognized but cannot be identified as one character of the character set, cont
