1. Data recognition equipment comprising:

  • dictionary means for storing partial pattern data and pattern data;

    inputting means for inputting segmented pattern data;

    recognition means for recognizing partial pattern data among input pattern data from said inputting means by comparison with the partial pattern data stored in said dictionary means;

    selection means for selecting a candidate pattern having the recognized partial pattern from said dictionary means;

    first comparing means for comparing the selected candidate pattern with the input pattern data for each part other than the recognized partial pattern data and for outputting a distance obtained from the comparison in correspondence to the selected candidate pattern;

    second comparing means for comparing the output distance from said first comparing means with a reference value; and

    third comparing means for comparing the selected candidate pattern with the input pattern data at a part of the recognized partial pattern if it is determined that the distance is smaller than the reference value by said second comparing means; and

    output means for outputting character information representing the candidate pattern compared with the input pattern data by said third comparing means.
