[0009]
FIG. 2 is a block diagram showing the connection between the internal configuration of the potential generator 1 and a commercial power source according to an embodiment of the present invention. In FIG. 2, 10 is a single-phase 100V commercial power source, 11 is an outlet, and has electrodes 11a and 11b. The electrode 11b detects the ground line side of the commercial power source by the AC ground line detection described later. Connected and grounded.
[0010]
The internal configuration of the potential generator 1 includes a power plug 12 having electrodes 12a and 12b, a fuse 13, a line switching unit 14, a leakage current detection unit 15, a ground line connection unit 16, a control circuit 17, a power supply unit 18, and an output circuit 19 The protective circuit 20 and the like are connected to an external device and a human body through an output terminal 1a that outputs a positive potential and a ground terminal 1b.
[0011]
Next, the operation of the potential generator 1 having such a configuration will be described.
The potential generator 1 is driven by a 100 V single-phase commercial power supply, and outputs a DC voltage rectified by the power supply unit 18 through an output circuit 19 and a protection circuit 20 controlled by a control circuit 17. The treatment is performed by being connected to the conductor 4 and the load conductor.
[0012]
The function of detecting the ground line of the commercial power source of the potential generator 1 operates when the output setting is selected and when the negative charge mode, that is, the treatment is performed.
To detect the ground line of the commercial power source, the line switching unit 14 selects one of the input lines 12a or 12b, and leaks a leakage current between the selected one line 21 and the output terminal 1a and the ground terminal 1b. It is detected by the current detector 15.

Even when the device is used while the ground terminal 1b is grounded by detecting the ground side of the input line as described above, the leakage current detector 15 continues to monitor the leakage current, and the leakage current value exceeds the microampere order level (level 2). In this case, the above-mentioned ground determination of the input line is performed again.
