Abstract

PURPOSE:To conserve power consumption by certainly cutting off the power supply of a pulse wave measuring part after the elapse of a predetermined time, by discriminating the difference between a pulse wave signal and noise other than a pulse wave and continuing the measurement of a time for automatic power-OFF for the input of noise. CONSTITUTION:The frequency corresponding to the min. pulse rate among the pulse rates measurable from a living body is set to f1 and the frequency corresponding to the max. pulse rate is set to f2 and only the signal present within a range from the lower limit frequency f1 to the upper limit frequency f2 in the detection output due to a pulse wave sensor 2 is regarded as pulse wave input to clear the count number of an automatic power-OFF counter 7. When a signal not present within said range, that is, a signal having an extremely short cycle or a signal having an extremely long cycle is inputted, said signal is judged as noise to continue the counting of the counter 7. Therefore, when pulse like noise low in repeating frequency or continuous noise high in repeating frequency enters accidentally, the power of a pulse wave forming circuit 3 is cut OFF after a predetermined time without clearing the counter 7.
