Claims

[Claims for Utility Model Registration] A dictionary memory 30 that stores standard feature values DD _i (i=1 to n) of characters; a feature ID of characters to be recognized and the standard feature value D;
Distance calculation unit 4 that calculates distance data X _i from D _i
0, a sort memory 60 which is composed of a dual port memory and stores distance data from the first candidate character to the mth candidate character in a predetermined order, and a sort memory 60 that stores distance data from the first candidate character to the mth _candidate character in a predetermined order. , distance data XA ₁ of m candidate characters from one port P1 of the sort memory 60 to the present ~XA _m is read out one by one and compared with the distance data X _i , so that among the m+1 candidate characters, the first candidate character to the mth candidate character are newly stored in the sorting memory 60 in a predetermined order. A dictionary search device for character recognition, comprising: a sorting means 50 for sorting and storing the rearranged information in the sort memory 60 via the other port P2 of the sort memory 60.
