徴とする回転速度検出装置。[Claims for Utility Model Registration] A pulse generator that outputs a pulse train with a frequency corresponding to the rotational speed of a rotating body; Counting means that sequentially counts the number of pulses per unit time of the pulse train; Each time the counting is completed. , a count value correction means for subtracting the previous count value from the current count value, adding the deviation to the current count value, and outputting the addition result as rotation speed data from the current time point to the next time point of completion of counting. A rotation speed detection device characterized by:
