とする速度計測装置。[Claims for Utility Model Registration] Speed detection means for converting the speed of the object to be measured into a pulse signal having a repetition frequency proportional to the speed of the object to be measured, and repeating the pulse signal output from the speed detection means at a predetermined constant gate time. pulse count means for counting, pulse count value storage means for storing a predetermined number of pulse count values output from the pulse count means at each end of each gate time, and a predetermined number of pulse count values stored in the pulse count value storage means. A speed calculation means that adds a pulse count value at each end of each gate time and calculates a speed based on the added value, and a speed display means that displays the calculated speed output by the speed calculation means in a predetermined format. A speed measuring device characterized by:
