PROBLEM TO BE SOLVED: To increase the variations of an electric stimulation (output wave- form) of a pulsing health apparatus. SOLUTION: A wave-form generator 4 generates a pulse wave having a designated frequency and a duty ratio based on a control signal fed from a CPU1, and feeds the pulse wave to a driver circuit 6. A D/A converting circuit 5 forms a level signal corresponding to the control data fed from the CPU1, and feeds the level signal to the driver circuit 6 as a gain signal. The driver circuit 6 forms a pulse wave for which the pulse wave fed from the wave-form generator 4 is amplified by a gain corresponding to the level signal fed from the D/A converting circuit 5, and feeds the pulse wave to an electrode 7. Thus, an output pulse having an arbitrary frequency, a duty ratio and a voltage selected by a user can be obtained. COPYRIGHT: (C)2003,JPO
