Abstract:
1. A living body stimulating apparatus for applying an electric stimulus to a living body, said apparatus comprising conductor elements to apply a stimulation signal to said living body by allowing an electric current to flow from the conductor elements to said living body, which comprises: a stimulus generator means for outputting rectangular wave pulse groups repeatedly to said conductive elements as stimulation signals, said stimulus generator means outputting stimulation signals formed by varying the density of a plurality of on-pulses constituting the rectangular wave pulse groups during an output period of said rectangular wave pulse groups, so that said rectangular wave pulse groups defining pulse groups are alternately positive and negative, while the density of said on-pulses gradually increases from a rising edge of the rectangular wave pulse group until about the middle of a predetermined time width thereof and then gradually decreases until a falling edge of the rectangular pulse group.
