PROBLEM TO BE SOLVED: To provide low-frequency therapy equipment capable of obtaining stable voltage for examination for examining the state of an attached pad by a simple structure and at a low cost. SOLUTION: The low-frequency therapy equipment examines the state of attached pads 300 by examining whether an electric current runs between the pads 300 and 300 by applying the voltage for examination. The voltage for examination used herein is generated from the output voltage V4 of a power supply circuit 242 set for generating the driving voltage V2 of a CPU 230. The power supply circuit 242 is a circuit for generating the driving voltage V2 by stabilizing the battery voltage V1. COPYRIGHT: (C)2008,JPO&INPIT
