器。 An electronic percussion instrument comprising a plurality of impact detection devices each having a striking surface in the same housing, and in which the output signal of each of the striking detection devices is used as a signal for driving a sound source, the output of each sensor provided corresponding to each of the striking surfaces. A blow detecting means provided independently for each sensor so as to set a predetermined threshold value to detect the blow detecting means, and a comparing means mutually comparing the values of the outputs of the respective blow detecting means. The value of the output of the impact detection means is smaller than the value of the output of any other impact detection means,
and the value of the output of any of the other impact detection means,
If the comparison means determines that the ratio or difference with the value of the output of the arbitrary impact detection means is larger than a predetermined value, the output of the arbitrary impact detection means is not used as the signal for driving the sound source. An electronic percussion instrument.
