    • A hitting position detecting device includes: a golf club which includes a shaft having a grip portion and a head portion having a face portion with a hitting surface and a rear surface and attached to the front end of the shaft; vibration wave sensors which is arranged on the side of the rear surface of the face portion and is fixed to the head portion so as to output electrical signals in accordance with a vibration wave generated upon hitting of the face portion; a calculation unit which detects arrival times in the vibration wave sensors of the vibration wave generated in the face portion upon hitting of a ball on the basis of the electrical signals, calculates a hitting position of the ball in the face portion on the basis of a difference in the plurality of arrival times, and then outputs the result as a hitting position signal; a display unit which displays the hitting position in the face portion on the basis of the hitting position signal output from the calculation unit; and a power source which supplies power to the vibration wave sensors, the calculation unit, and the display unit.
    • 打击位置检测装置包括:高尔夫球杆,其包括具有抓握部分的轴和具有带有击球面的表面部分和后表面的头部,并且安装到所述轴的前端; 振动波传感器,布置在面部的后表面侧,并固定到头部,以便根据面部发生的振动波输出电信号; 计算单元,其基于电信号来检测在击球时在面部中产生的振动波的振动波传感器中的到达时间,基于电气信号计算面部中的球的击球位置 多个到达时间的差,然后将结果作为击打位置信号输出; 显示单元,其基于从计算单元输出的击打位置信号显示面部中的击球位置; 以及向振动波传感器,计算单元和显示单元供电的电源。
