Next, the operation of this embodiment will be described with reference to FIGS.

In FIG. 4, first, the microcomputer 20 of the main body 100 is in the "STOP" state in which clock oscillation is stopped in the initial state where the key switch input unit 1 is not operated (S1). When any of the key switches 1a, 1b, 1c of the key switch input section 1 is operated in this state, the microcomputer 20 oscillates a clock from the "STOP" state and outputs the information signal corresponding to the input key switch. Moves to the "sending" state for sending (S2) and starts the built-in timer. At this time, the LE on the display unit 22 corresponds to the key switch operated simultaneously.
D flashes. When the "strong" key switch 1d and the "weak" key switch 1e are operated, the microcomputer 20
The "OP" state is continued.

For example, a case where the "tap 1" key switch 1a is pressed will be described.

When the "tap 1" key switch 1a is pressed, the microcomputer
20 outputs the code h corresponding to the key switch 1a to the conversion circuit 21. When the code h is input to the conversion circuit 21, a resonance current flows in the transmission coil L and the capacitor C. As a result, the transmission coil L outputs the transmission signal T1 of "Tap 1" shown in FIG. 5 by the carrier wave of 5 KHz.

The transmission signal T1 is transmitted after [C0 C1 C2
C0 C1 C2] is composed of a pulse train of [1 0 1 0 1 0]. The pulse forming the transmission signal T1 has a width of about 10 msec, and the transmission coil L resonates during this period.
The transmission signals T2 to T6 other than the transmission signal T1 of "Tataku 1" are as shown in Table 1.

After either of the transmission signals is transmitted, the microcomputer 20 is in the "key input waiting" state (S3). In this state, the respective key switches 1a-1f can be operated. In this "key input waiting" state, when any of the key switches 1a to 1c is operated to change the mode, the timer of the microcomputer 20 is cleared each time. When the timer detects that a predetermined time has elapsed, the microcomputer 20 outputs a "off" code to the conversion circuit 21 and enters the "STOP" state.

Next, the operation of the conductor section 200 will be described.

As shown in FIG. 6, the microcomputer 40 of the conductor unit 200 is in the "STOP" state in which the clock is stopped and the instruction cannot be accepted in the initial state, as in the case of the microcomputer 20 ( S1
1) 、 ON / OFF switch SW provided on the upper surface of conductor 200a
When is pressed, the clock oscillates and enters the "READY" state in which only instructions can be accepted (S12). At this time, the microcomputer 40 turns on / off the low level with respect to the transistor TRs.
Output F signal and turn on transistor TRs. As a result, the relay section 3 is energized to be in a receivable state. Microcomputer
When 40 is in the "STOP" state, the ON / OFF signal is at a high level and the relay section 3 is not energized. In the "READY" state, the operation command, that is, the information signal corresponding to the transmission signal converted from magnetism to electricity by the conversion circuit 31, is not accepted, and the operation command is awaited or the detection signal e output from the skin detection circuit 7 is low. Waiting for a level The microcomputer 40 has a built-in timer, and the "READY" state is a predetermined time (for example, 3
(STANDARD) for a few minutes) to reduce battery consumption
Return to the "OP" state.

In the "READY" state, the signal e of the skin detection circuit 7 is at a low level, and "Tapping 1", "Tapping 2", "Mumping"
When any one of the information signals is received, or when one of the information signals is received and the signal e changes from the high level to the low level in that state, the microcomputer 40 shifts to the “treatment” operation. Yes (S13). The skin detection circuit 7 outputs a low-level signal e if the conductors 200c and 200d are attached to the human body. In the "treatment" operation, the microcomputer 40 operates the oscillation circuit 41 and outputs the drive pulse d ₂ to the pulse output circuit 5 in response to the information signal input from the low-pass filter 32. The oscillating circuit 41 receives the signal from the microcomputer 40
As shown in FIGS. 8 to 8, the drive pulse d ₁ is output to the first transistor TR ₁ of the pulse output circuit 5. The first transistor TR1 is turned ON / OFF by the drive pulses d _1, to interrupt the excitation current flowing from the power supply to the coil L1. Then, the boosted pulse voltage due to the exciting current is accumulated in the capacitor C1 via the diode D1. Then, when the drive pulse d ₂ output from the microcomputer 40 rises, the second transistor TR 2 becomes O
Then, the stored energy stored in the capacitor C1 is applied as a stimulation pulse O of a low frequency pulse to the human body output between the conductors 200c and 200d. The drive pulse d ₁ is the first transistor TR while the drive pulse d ₂ is not output.
It is output to 1, and when the number of pulses decreases,
The stored energy stored in the capacitor C1 decreases,
As shown in the figure, the intensity of the stimulation pulse O output to the human body becomes weak. The stimulation pulse O is set by operating the “strong” key switch 1d and the “weak” key switch 1e of the key switch input unit 1 of the main body 100. In other words, while operating the key switch 1a of "Tataku 1", while performing low frequency treatment in that mode,
"Strong" key switch 1d or "weak" key switch 1e
When is operated, the information signal is input to the microcomputer 40 to change the drive pulse d ₁ .

During the low frequency treatment, one of the conductors 20
When 0c and 200d are peeled from the human body, the signal e output from the skin detecting circuit 7 becomes high level, and the microcomputer 40 suspends the "treatment" operation and enters the "READY" state. Alternatively, when the information signal indicating the end of the operation is received during the treatment, the "READY" state is similarly set. And the "READY" state is for a predetermined time (for example, 3
If the ON / OFF switch SW is pressed, the microcomputer 40 enters the "STOP" state. If the ON / OFF switch SW is pressed during treatment, the microcomputer 40
Become a P "state, stops the output of the drive pulse d _2.
The microcomputer 40 has a built-in timer for a predetermined time (for example, 15 minutes) after first receiving the mode information signal.
Perform the "treatment" operation, and if the predetermined time elapses, "RE
ADY ”state.

Here, the timer operation of each of the microcomputers 20 and 40 will be described with reference to FIGS. 9A and 9B.

First, when the ON / OFF switch SW of the conductor 200a is pressed,
200 is ready for reception. Next, when any of the key switches 1a to 1c of the key switch input unit 1 on the main body 100 side is pressed, the timer of the microcomputer 20 in the main body 100 starts,
Moreover, the conductor section 200 receives the electromagnetic wave from the main body 100, and the microcomputer 40 starts the timer. After a lapse of a predetermined time (for example, 15 minutes) thereafter, the microcomputer 20 stops the timer, outputs information indicating the end of the treatment to the guiding portion 200, and at the same time, the microcomputer 20 enters the "READY" state. Upon receiving the information from the main body 100, the microcomputer 40 of the conductor section 200 enters the "READY" state (Fig. 9A).

When the conductor 200 does not receive the information indicating the completion of the treatment from the main body 100, the microcomputer 40 in the conductor 200 stops the timer after a predetermined time by the timer and the microcomputer 40
To "READY" state (Fig. 9B).

It should be noted that the transmitting coil of the main body and the receiving signal coil of the conductor portion may be composed of a plurality of, for example, two, and the carrier wave may be output from each of the transmitting coils with the phase shifted by 90 °. In this case, electromagnetic waves are output from the main body in all directions, and reception of electromagnetic waves becomes easy.

(G) Effect of the Invention According to the present invention, since power supply to the relay section of the guiding section is stopped except for the treatment operation, the power consumption of the guiding section can be reduced. This prolongs the life of the battery used as a power source.
