PROBLEM TO BE SOLVED: To obtain an impact blow detector of an electronic percussion instrument device which has an excellent impact blow feel and is extremely small in impact blow sounds by providing this instrument device with a head having an impact blow surface comprising net-like blanks and an impact blow detecting means which detects the impact blow on this head as an electric signal. SOLUTION: The impact blow detector 10 is provided with a head sensor 14 which detects the impact blow on the head 12 having the impact blow surface comprising the net-like blank and a rim shot sensor 18 for detecting the impact blow to a rim 16. The head 12 is formed by laminating a first net 56 woven by plain weave intersecting longitudinal and transverse fibers orthogonally with each other and a second net 58, as the net-like blanks, in such a manner that the each other's weave directions intersect diagonally with each other, i.e., intersect with each other at an angle smaller than 90 deg. and adhering the laminated nets to a frame 60. The rim 16 is formed by integral molding of metallic materials and comprises an edge part 66 bored with hole parts 64 penetratable with engaging pins 54 in its outer peripheral part and a rim impact blow part 68 formed on the inner peripheral side thereof. |
