Abstract
PURPOSE:To execute the measurement with high accuracy even in case of a high speed, by constituting the titled device so that a detector outputs several pulses, before a first counter counts a clock of a prescribed value. CONSTITUTION:In case a gear is rotating at a high speed, when a counter 4 counts N pieces or more of clock signals, a comparator 10 provides two's power pieces of count outputs, and at a timing by which a pulse is outputted from a waveform shaping circuit 3, an AND circuit 8 outputs a high signal, and a latching circuit 12 is triggered. At this time point, the latching circuit 12 latches a count value of a counter 9 and the counter 4. In this case, the count value of the counter 4 is not one interval of a tooth 1a of a gear 1 but becomes that of a several interval portion, therefore, a rotating speed is detected without deteriorating the accuracy even at a high speed.
