1. A character recognition apparatus for identifying a handwritten of a predetermined set of characters formed from at least one primitive selected from a predetermined set of primitives illustrated in FIG. 3 with said set of primitives forming said handwritten character being written in an order determined by pre-defined rules, said apparatus comprising:

  • input means for receiving successively and in accordance with said pre-defined rules each of the primitives forming said handwritten character and generating input signals for each of said received primitives;

    processing means for receiving said input signals and identifying each of said primitives received by said input means, said processing means generating a character code representing said handwritten character upon identification of said primitives forming said handwritten character;

    storage means for storing a character code and an associated output code for each of the characters in said predetermined set;

    comparing means for comparing said character code generated for said handwritten character with said character codes in said storage means to identify said handwritten character; and

    output means in communication with said comparing means and generating a reproduction of said handwritten character upon the identification thereof by said comparing means.
