PURPOSE:To execute in high-speed sequence processing of selecting category group of higher order from multiple categories by carrying out simultaneously arithmetic processing and selection processing of categories of higher order utilizing maximum value memory and max. value detection circuit. CONSTITUTION:The max. value memory 5 has written before the sequence processing all the large values as initial values and the max. value from each max. memory 5 of distance calculated executed for the respective categories is detected and this max. value and the size of distance obtained by category unit are compared by the comparison circuit 7. In case the distance value is larger than the max. detected value, the arithmetic processing of the next category distance is executed; conversely, when the distance value is smaller than the max. detected value, the distance value is replaced with the max. value in the max. value memory 5. At the same time the category No. (contents of the sorting results memory 9) corresponding to the max. value of the distance value in the max. value memory 5 is substituted in place of the existing category number.
