Next, the operation of the above embodiment will be explained.

When not in use, the conductor cords 22 of the pair of conductor sections I2 are wound up around the cord reel section l4 of the treatment device main body section l1, and the conductor electrodes 21 of the conductor section I2 are connected to the treatment device main body section 1.
It is stored in the conductor electrode storage section 15 of 1.

In this state, as shown by the solid lines in Figures 1 and 2,
A pair of conductor electrodes 2l are respectively inserted into the storage portions 66 on both the front and rear surfaces of the storage plate 6l, and the adhesive pads 25 of both conductor electrodes 2l are adhered to the sheet 74 on the bottom surface of each storage portion 66. , the storage plate 61 is stored in the storage plate chamber 37 of the treatment device main body 11. Further, the changeover switch 45 is turned off, and its movable contact d is connected to the fixed contact h, and the movable contact e is connected to the fixed contact 1.

Note that when charging the secondary battery 42, the power switch 44 is turned off and the movable contact a is connected to the fixed contact b. In this state, when the female connector 43 is connected to a 100V AC power supply, the transformer 83 reduces the pressure from the AC power supply, and the diode bridge 84 performs rectification to supply DC current to the secondary battery 42. . This charges the secondary battery 42.

Note that during charging, the light emitting diode 47 lights up.

In use, first, the power switch 44 is turned off, and its movable contact a is connected to the fixed contact C. At this point, in cold weather such as winter, be sure to close the conductor electrode storage area before use.
The conductor electrode 21 housed in 5 can be preheated and warmed in advance. To preheat the conductor electrode 21, the movable contact d of the changeover switch 45 is connected to the fixed contact f, and the movable contact e is connected to the fixed contact j. This results in
Since the output port ■, which is always HIGH, of the microcomputer 91 is connected to the input port ◎, this input port 0 becomes HIGH. On the other hand, the input port ■ remains LOW, but when the input port ■ is LOW and the input port ■ becomes HIGH, the output port ■
also becomes HIGH, turning on transistor 141.

As a result, current flows from the battery 42 to the PTC thermistor 72 via the contacts d and f and the transistor 141, and the PTC thermistor 72 generates heat.

The heat generated by this PTC thermistor 72 located in the isolation section 65 of the storage plate 61 on which the pair of conductor electrodes 2l are sandwiched in the conductor electrode housing section 15 causes the pair of conductor electrodes 21, especially the adhesive pads 21, to is heated.

Note that even if the contacts d, f, e, and j of the changeover switch 45 are not disconnected, if a certain period of time elapses, a timer set in the microcomputer 91 will turn the output port LOW to turn off the transistor 141. The PTC thermistor 72 stops generating heat. The time period during which the output port (2) is held at HIGH is set, for example, to a length that allows the temperature of the outside air to rise sufficiently even if it is 0°C. Eventually, the adhesive pads 25 of both conductor electrodes 2l are heated to a temperature slightly higher than body temperature.

At the time of treatment, first, the storage plate 61 is rotated, and the storage plate 6l is moved from the storage plate chamber 37 of the treatment device main body 11 to the upper outside through the storage plate chamber opening 39, as shown by the chain line in FIG. protrude in one direction. And the third
As shown in the figure, the sheets 74 on both sides of the storage play}61
Peel off the adhesive pad 25 and remove the conductor electrodes 21 of both conductor parts 12, respectively. Along with this, the cord reel section 14 in the treatment device main body 11 rotates, and the conductor cords 22 of both conductor sections l2 are pulled out from this cord reel section 14, but these conductor cords 22 are further pulled. Pull out the required length.

Thereafter, the storage plate 61 is rotated in the opposite direction to be stored in the storage plate storage chamber 37 again, and the storage plate chamber opening 39 is
It is preferable to close it with the lid part 68 of the storage plate 6l. This way, the storage plate 61 will not get in the way.

In this state, the conductor cord 22 is led out from the cord passage hole 69 formed in the upper surface of the treatment device main body 11.

Next, both conductor electrodes 21 are attached to desired positions on the human body by applying the adhesive pads 25 directly to the skin. At the same time, when the selector switch 45 is set to the "tapping" mode or the "kneading" mode, a high voltage pulse is generated at a low frequency by the circuit section l3 in the treatment device main body section ll, and this high voltage pulse is , is transmitted to the adhesive pad 25 of both conductor electrodes 2l via the contact plate and fixed contact of the code reel part l4 and both conductor cords 22,
It is applied to the human body from here. This causes an instantaneous current to flow through the human body, providing stimulation and treating stiff shoulders and muscle pain. Note that the type of pulse to be output can be selected depending on whether the selector switch 45 is set to the "beat" mode or the "kneading" mode. "Tataki"
In mode, high voltage pulses are output at regular intervals and
In the "kneading" mode, a constant output period in which high voltage pulses are output at relatively short cycles and a constant rest period are repeated. Further, by pressing the intensity adjustment switch 46, the voltage, that is, the intensity of the high voltage pulse output to the human body can be adjusted stepwise.

Here, the operation of the circuit section 13 during low frequency treatment will be explained.

In the "tapping" mode, the movable contact d of the changeover switch 45
is connected to the fixed contact g, and the movable contact e is connected to the fixed contact k. In this state, the output port ■ of the microcomputer 91 is the input port 0. ■ Not connected to
Since these input ports ◎ and ■ are LOW, the microcomputer 91 determines that it is in the "beating" mode. On the other hand, in the "kneading" mode, selector switch 4
The movable contact d of No. 5 is connected to the fixed contact i, and the movable contact e of No. 5 is connected to the fixed contact m. In this state, the output port ■ of the microcomputer 91 is connected to the input port ■, and this input port ■ becomes HIGH, and the input port ◎ is LOW, so the microcomputer 91 is in the "kneading" mode. I judge that.

Note that in the "beat" and "kneading" modes, the output port [phase] is LOW, so the PTC thermistor 72 does not operate. On the other hand, input boat ◎ is HIG
When the PTC thermistor 72 is operating at H, the following operation during low frequency treatment is not performed.

Then, when the strength selection switch 46 is turned on with the conductor electrode 21 attached to the human body, and the input port (2) becomes HIGH, the microcomputer 91 starts a low frequency treatment operation.

First, the output port of the microcomputer 91■,■
A number of high frequency pulses from one or both of the transistors 104 . Output to the base of tos. When the outputs of the output ports ■ and ■ become HIGH, the transistors 104 and 105 are turned on, and current flows from the battery 42 to the coils 102 and 103 via these. After that, the outputs of the output ports ■ and ■ become LOW, transistors 104 and 105 are turned off, and the coil I (
When the current flowing through the coils +02' and 103 is cut off, a high voltage is generated in the coils +02' and 103 due to a back electromotive force. By repeatedly charging the capacitor 114 with this high voltage, the charging voltage of the capacitor 114 is sufficiently increased.

Note that the input port of the microcomputer 91 is set to HIGH when the strength selection switch 46 is turned on.
When it becomes H, the output port ■. ■Switch the number of outputs of high-frequency pulses from . This allows capacitor 114
The charging voltage is variably set, and the strength of the therapeutic electric pulse can be adjusted.

After the capacitor 114 has finished charging, the output port ■, which had been LOW until then, temporarily becomes HIGH.
It becomes H. As a result, the transistor 123 of the pulse output circuit 126 is turned on, the transistor 121 is turned on, and the high voltage charged in the capacitor 114 is output as a pulse from the conductor electrode 2l to the human body.

Then, the output port ■, which had been LOW until then, temporarily becomes HIGH. As a result, the transistor 116 turns on, and the charging voltage of the capacitor 114 becomes Ov.
This capacitor 114 is discharged until . Thereafter, as described above, the capacitor 114 is again
begins charging. In this way, the series of operations described above are repeated at regular intervals.

Note that when the pulse is output to the conductor electrode 21, if the conductor electrode 2l is not attached to the human body, no current will flow between the conductor electrodes 21, so the transistor 13
3, no base current flows through this transistor 133.
is in the off state. Therefore, although the input port (2) of the microcomputer 91 is HIGH, the microcomputer 91 determines that the conductor electrode 2l is not attached to the human body. In this case, the microcomputer 91 stops the output from the output ports (2) and (4), and stops the low frequency treatment operation. On the other hand, if the conductor electrodes 2l are attached to the human body, a current flows between these conductor electrodes 21, and a base current also flows through the transistor 133, so that the transistor 133 is turned on. Therefore, the input port (2) becomes LOW, and the microcomputer 91 determines that the conductor electrode 2l is attached to the human body. In this case, pulses continue to be output to the conductor electrode 2l. Note that, for example, for two seconds after the input port (2) becomes HIGH, a pulse is always outputted to the conductor electrode 2l unconditionally.

Further, after the treatment, the changeover switch 45 is turned off. In this state, the power supply to the microcomputer 91 is cut off, so the low frequency treatment operation of the circuit section 13 is stopped. At the same time, the adhesive pad 25 is peeled off from the human body and both conductor electrodes 2l are removed.

For storage, the storage plate 61 is rotated to project out of the storage plate chamber 37 of the treatment device main body 11. Then, the sheets 7 on both the front and rear sides of the storage plate 61
4, the adhesive pads 25 of the conductor electrodes 21 of both conductor portions l2 are pasted, respectively. At this time, each conductor electrode 21 is made to fit within both storage portions 66 of the storage plate 61,
Each conductor cord 22 is passed through the cut arrow portions 67 of both positioning walls 64, respectively. Next, by hooking a finger on the finger hook recess 58 of the cord reel section 14 and rotating the cord reel section 14, both conductor cords 22 are wound up and stored on the reel body 51 of the cord reel section 14. When these conductor cords 22 are wound up to the end, the conductor cords 2 are caught in the notch 67 of the storage plate 61 in a tense state.
2 pulls the storage plate 61 downward, the storage plate 61 is stored in the storage plate chamber 37 of the treatment device main body l1, and the storage plate chamber opening 39 is closed by the lid 68 of the storage plate 61.
