The pressure is gradually reduced at a speed of about Hg / sec. In the process of such a slow pressure drop, S
At 5, a blood pressure value determination routine is executed. In this blood pressure value determination routine, each time a pulse wave, which is a pressure oscillation of the cuff 28, is generated, the amplitude of the pulse wave is obtained, and it is determined whether or not the difference between the pulse wave amplitudes is the maximum value. the cuff pressure P _C at that time is determined as the systolic blood pressure value or diastolic blood pressure when a.

Next, in S6, it is determined whether or not the determination of the blood pressure value has been completed, that is, whether or not both the systolic blood pressure value and the diastolic blood pressure value have been determined. Initially, the determination in S6 is denied, so that S5 and subsequent steps are repeatedly executed. If the systolic blood pressure value and the diastolic blood pressure value are both determined during the repeated execution of S5 and subsequent steps, the determination in S6 is affirmative, so that the cuff 28 is rapidly evacuated in S7, and the systolic blood pressure value and The blood pressure value is displayed on the systolic blood pressure display 36 and the diastolic blood pressure display 34, and then, in step S9 corresponding to the transmission control means 86.
