PURPOSE: To facilitate pluralization of the number of sensors so that many positions are measured simultaneously, and also, to improve an examinee's constraint sense, and to improve portability.
CONSTITUTION: In a detecting part, an active quantity detecting sensor generates a pulse signal in accordance with an active quantity of each part of an examinee. The pulse signal is modulated, and thereafter, transmitted as a radio wave to a measuring instrument main body 20. This radio wave is received by a receiving part 21 of the measuring instrument main body 20, and thereafter, transmitted to a demodulating part 22, in which an active quantity detecting signal is demodulated. The demodulated active quantity detecting signal is fed to a CPU 24. The CPU 24 converts the active quantity detecting signal from each detecting part outputted from a demodulating part 22 to data at every unit time, and writes it in a recording part 23.
