    • An iron type golf club head comprising: a face plate provided with face grooves; and a head main body arranging the face plate on a front surface thereof, wherein the face plate comprises a peripheral edge part firmly fixed to the head main body, and a non-supported part forming an area surrounded by the peripheral edge part and having a back surface apart from the head main body, and the non-supported part satisfies the following equations (1), (2) and (3): 1.1≦ha/hb≦1.6;  (1) 1.1×(ha+hb)/2≦hc≦1.5×(ha+hb)/2;  (2) 18 (mm)≦hb≦38 (mm)  (3) (in which ha is a toe side height (mm) of the face groove in an end portion closest to the toe side, hb is a heel side height (mm) of the face groove in an end portion closest to the heel side, and hc is an intermediate height (mm) of the face groove in an intermediate position between the end portion on the toe side and the end portion on the heel side).

    • A ball motion measuring apparatus has a CCD camera having a multi-shutter which can open and close successively; strobes; a swinging speed measuring sensor; and a controlling/computing device connected to the CCD camera, the strobes, and the swinging speed measuring sensor. The swinging speed measuring sensor outputs a trigger signal for opening/closing the shutter to the CCD camera when the swinging speed measuring sensor detects passage of a golf club. Upon receipt of the trigger signal, the multi-shutter opens and closes successively. Synchronously with the opening/closing of the multi-shutter, the strobes emit flashlight sequentially. In this manner, a plurality of images of a golf ball driven by the golf club are photographed in a one-image frame.
    • 球运动测量装置具有能够连续打开和关闭的多快门的CCD照相机; 频闪 摆动速度测量传感器; 以及连接到CCD照相机,闪光灯和摆动速度测量传感器的控制/计算装置。 当摆动速度测量传感器检测到高尔夫球杆的通过时,摆动速度测量传感器输出用于将快门打开/关闭到CCD照相机的触发信号。 在接收到触发信号时,多重快门依次打开和关闭。 与多重快门的打开/关闭同步,闪光灯顺序地发射手电筒。 以这种方式,在单图像帧中拍摄由高尔夫球杆驱动的高尔夫球的多个图像。
