As the power source 8 for the internal circuit of each of the above-described embodiments, a battery is used to realize portability of the device. As this battery, a polyacene secondary battery or a hydrogen storage / alloy secondary battery is used in consideration of environmental hygiene.

In each of the devices of the above-mentioned embodiments, it is desirable to measure the impedance while the grip portion is securely gripped. Therefore, in order to perform the measurement with higher accuracy, it is sufficient to detect the gripped state of the grip, that is, the contact of the palm with the electrode, and start the measurement in response to the detection output. FIG. 18 shows that when the contact switch is turned on,

The pressure is applied to the pressure sensitive rubber sensor 46, and the resistance value changes accordingly. When the resistance value changes, in the circuit of FIG. 19B, the terminal voltage of the pressure sensitive rubber sensor 46 also changes, and this voltage is amplified by Amp 47, added to the comparator 48, and compared with the reference voltage. Then, the comparator 48 sets High or Low depending on the presence or absence of pressure.
The logic signal of is output. The CPU 28 responds to this,
When there is pressure, a measurement start command signal is output.

9, the electrode signal switching unit 49 is switched to the connection shown in FIG. This connection makes the electrodes 18 and 20 on the right palm side OP
It is set to EN and connected so that the signal from the signal generator 21 is applied to the electrodes 17 and 19 on the left palm side.
7 and 19 are connected to the input of the differential amplifier 22, and a current flowing between the electrodes 17 and 19 and through the left palm,
The contact resistance between the left palm and the electrodes 17 and 19 is measured by the potential difference between both electrodes.

After the contact resistance of the left palm is obtained, the contact resistance of the right palm is then measured (ST25). This processing is also performed by the CPU
The switching control signal from the electrode signal switching unit 49
Made by sending to. By the switching processing in this step, the connection of the electrode signal switching unit 49 becomes as shown in FIG. In this connection, the electrodes 17 and 19 on the left palm side are set to OPEN and the electrodes 18 and 2 on the right palm side are reversed, contrary to FIG.

Next, it is judged whether or not the measured resistance values of both palms are below a specified value (ST26).
The gripping force of the grips 12 and 13 of the subject is still insufficient, and a message "grasp the grips correctly" is displayed on the display 16 (ST27), the process returns to ST24, and ST24 to ST27. The process of is repeated. When the resistance value of both palms is equal to or less than the specified value in ST26, it is determined that the grip is normally gripped, the measurement start is displayed on the display unit (ST28), and the subsequent steps from ST29 to ST31 are shown in FIG. The same processing as ST10 to ST12 is performed.
