Claim 4:
5. The detection device according to claim 3, wherein the controller sets, as a time corresponding to a falling end point of the peak, an initial time when the value of the second-order differential waveform changes from a negative value to a positive value and the value of the first-order differential waveform is a negative value in the direction in which time elapses from the time corresponding to the peak top of the peak, and when the time corresponding to the peak top of the peak and the time corresponding to the falling end point of the peak are out of a predetermined second period, the controller discriminates a rising start point of a next peak in the direction in which time elapses from the time corresponding to the peak top of the peak.
