Abstract

PURPOSE:To achieve a higher detection accuracy while reducing the interval of extracting the results of detection, by using a plurality of measuring means to start counting sequentially at an interval time shorter than the time required for one rotation of a gear for detection. CONSTITUTION:A plurality of measuring means 24 start counting sequentially at an interval time shorter than the time required for one rotation of a gear 22 for detection to measure a required time for counting as the counting of each set count value is done. Each time the counting means 24 measure the required time separately, a rotational speed detecting means 25 calculates a rotational speed based on the required time thus obtained and the revolutions of an engine during the period.
