Next, the calculation of the load and the load center will be described.
The subject holding the club C stands on the swing table 11 of the load measuring device 1 to take a stance. The loads of the swing base 11 are canceled in advance by the zero adjustment of the load converter 16 with respect to the outputs of the load cells 12, 13, 14, 15 at the four corners of the load measuring device 1, respectively.
The total WT of the outputs W1, W2, W3, W4 from 3, 14, and 15 is the load of the subject on the swing table 11 as in the following equation. WT = W1 + W2 + W3 + W4

Further, at this time, the outputs W1, W2, W3, W4 of the load cells 12, 13, 14, 15 are determined by the relationship between the position where the load is applied and the installation positions of the four load cells 12, 13, 14, 15. Because it will be different,
Center of load (X, Y) applied to the swing base 11 from these
Can be calculated. That is, the left-right direction component X and the front-back direction component Y of the load center (X, Y) expressed with the load cell 12 in FIG.
When the widths 2, 13, 14, and 15 are arranged at the four corners of the rectangular swing table 11 having a width in the X direction of a and a width in the Y direction of b, they are obtained by the following equation. X = (W2 + W3) × a / WT Y = (W3 + W4) × b / WT Further, if three or more load cells are arranged, the load center applied to the swing table 11 can be obtained.

The ball C hits the ball 21 at the club C. During this time, the measurement data from the measuring means S is sequentially stored in the main memory device 33, and at the same time, the current position of the load center (X, Y) is displayed on the graphic display 41 as a dot mark in real time. It In this case, when the right hitting mode is set, the club detection sensor 24 or the left hitting mode is set to detect the start time of the ball hitting operation except immediately before the impact time when the club C hits the ball 21. When the club detection sensor 25 finally switches from the state in which the presence of the head is detected to the state in which the presence of the head is not detected, it is detected as the start time of the ball striking action when the waffle action is completed, and The detection at the end time is a set time from the impact time, that is, the time when the ball detection sensor 23 detects the presence of the ball 21 on the support 22 and the time when the absence of the ball 21 on the support 22 is detected. The time after the elapse is detected as the end time of the ball hitting motion. Then, the main storage device 33
Based on the stored information, the data from the start time to the end time of the hitting motion detected as described above is displayed on the display device 4 as the measurement data during the hitting motion.

Therefore, when the hitting posture of the subject is right-handed and the hitting posture of the reference data is left-handed, or when the hitting posture of the subject is left-handed and the hitting posture of the reference data is right-handed, it is displayed on the display device 4. The left-right relationship between the measured data of the subject and the reference data is reversed as shown by the loci RI and R2 of the load center (X, Y) shown in FIGS. 5 and 6, and thus is stored in the main storage device 33. Data in the X direction of the time-series measurement data of the subject being examined or the external storage device 3
Data in the X direction out of the time-series reference data stored in FIG. 4 is converted by the arithmetic processing means 32 according to the following equation, so that the measurement data of the subject and the reference data have the same lateral relationship. Then, the converted data Xc is displayed on the display device 4. Xc = 2xb−X where xb is the coordinates of the point where the extension line from the position of the ball 21 in the Y direction intersects the X axis of the load measuring device 1.
