<P>PROBLEM TO BE SOLVED: To minimize delay of time until stimulation becomes effective while preventing unexpected stimulation from applying to cutaneous sensation. <P>SOLUTION: A current command value output part 10 outputs a current command value to a current variation control part 20. When voltage which an integrator outputs is lower than the current command value, a comparator 26 closes a switch 23 to input voltage obtained by amplifying fixed voltage outputted by a constant value output part 21 by a gain adjustor 22 to the integrator 24. Voltage outputted by the integrator 24 boosts in proportion to time to a value equal to the current command value and thereafter it is kept to be the value. The voltage is adjusted by a gain adjuster 25 and inputted to a constant current generation/control part 40, and current corresponding to this is inputted from a user skin electrode 44 to a mounting person 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
