<P>PROBLEM TO BE SOLVED: To provide an electric potential therapeutic apparatus capable of preventing a current from becoming undetectable because of the influence of a capacitor formed between a mat and a human body, and displaying an operating state in a display unit even if a DC voltage is output. <P>SOLUTION: The electric potential therapeutic apparatus includes: an AC voltage generating unit 11 for generating an AC voltage; a DC voltage generating unit 12 for generating a DC voltage; a switching unit 13 for switching these outputs; a superimposed signal generating unit 14 for generating a superimposed signal (AC signal) only when the generation of a DC voltage is detected; and a display unit 15 for displaying information indicating the operating state of the electric potential therapeutic apparatus 1, by measuring the superimposed signal superimposed on either the AC voltage output from the AC voltage generating unit 11 or the DC voltage output from the DC voltage generating unit 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
