Claim 6:
7. A hitting detection method of an electronic percussion instrument,
wherein the electronic percussion instrument comprises:
a head of which an upper surface is formed as a hitting surface;
a body part, which is cylindrical and has an opening at an upper end side of the body part, the opening is covered by the head;
a frame which is fixed to an inner peripheral side of the body part and faces a lower surface of the head;
a rim sensor which is supported by the frame and detects a hitting on an edge of the body part; and
a plurality of head sensors which are in contact with the lower surface of the head while being supported by the frame and detect a hitting on the hitting surface,
wherein the rim sensor is disposed at a center on the frame,
wherein the plurality of head sensors are disposed closer to an outer of the frame than the rim sensor and inner than an edge of the frame, and
wherein the frame comprises a rib which protrudes upward from a bottom surface of the frame and extends in a radial direction of the frame, and a pair of fixing parts which is separated from the rib and protrudes upward more than the rib from the bottom surface of the frame,
wherein the head sensors are supported by the frame through a first plate fixed to be bridged over an upper ends of the pair of the fixing parts such that the first plate avoids the rib,
the hitting detection method comprising:
detecting a hitting on the hitting surface on a basis of output values of the plurality of head sensors.
