ABSTRACT:
A character data processing apparatus discriminates machine-printed characters and hand-printed characters from each other and identifies a class of characters such as kanas (Japanese syllabary) or Kanjis (Chinese characters used in Japan). Characters filled by hand in the blanks on a form carrying machine-printed characters are also transformed automatically into machine-printed characters. Furthermore, characters corrected by hand on a document are transformed into machine-printed characters.
