The processing unit 3 includes an arithmetic unit 31 for performing arithmetic processing for obtaining a load and a load center and sequence control of the apparatus, an I / O interface 32 for transferring various data, and load and load center measurement information. It comprises a storage device 33 for storing, an operation console 34 for selecting an operation mode of the device and inputting various comments, an external storage device 35 for storing measurement information and the like. The display device 4 includes a graphic display device 4a and a plotter 4b. The graphic display device 4a displays a movement locus of the load center and the plotter 4b displays a time change of the load.

Next, the process of calculating the load and the load center by the arithmetic unit 31 functioning as the load measuring means M will be described. The test subject who holds the club C stands in a substantially center position on the swing table 1 while standing with the left and right feet on the two load detection tables 10 and 11, respectively. Explaining the load detection table 10 on which the subject places his left foot as an example, the load cells 12, 13, 14, at the four corners of the load detection table 10,
With respect to the output of 15, the stand load is canceled in advance by zero adjustment in the load converter 100, so that the total WL of the outputs W1, W2, W3, and W4 of the test subject on the load detection table 10 is obtained. The load on the left foot. That is, WL = W1 + W2 + W3 + W4 Furthermore, at this time, since the shared output of each load cell differs depending on the relationship between the position where the load is applied and the installation position of the four load cells 12 to 15, the load applied to the load detection base 10 from these outputs. You can seek the center.

That is, regarding the left-right direction component X and the front-back direction component Y of the load center expressed with the load cell 12 in FIG. 1 as the origin, the four load cells 12 to 15 have a width a in the X direction and a width in the Y direction. In the case of being arranged at the four corners of the rectangular load detection base 10 of b, it can be obtained from X = (W2 + W3) × a / WL Y = (W3 + W4) × b / WL. In addition, the load cells 12, 13,
Even when the arrangements of 14 and 15 are not at the four corners of the rectangle, the load center can be obtained by performing the correction unique to the geometrical arrangement of the load cells. Further, if three or more load cells are provided, the center of load applied to the swing table 1 can be obtained. The load detection base 11 on which the subject places his right foot is also configured the same as the load measuring device 10, and the load center of the load applied to the load detection base 11 can be obtained in the same manner as above. That is, the load centers corresponding to the left and right feet of the subject can be obtained.

For the load and center of load of both legs of the subject, that is, the whole body, the load applied to the load detection base 11 is W
If it is R, as in the case of the left foot above, the load cell 16
From the outputs W5 to W8 of ~ 19, WR = W5 + W6 + W7 + W8 The overall load WT is obtained by WT = WL + WR, and the load center is the distance between the load center corresponding to the left foot and the load center corresponding to the right foot of the subject. If it is L, it is located at a position WR × L / WT away from the load center corresponding to the left foot on the line segment connecting the left and right load centers, and this can be calculated.

As shown in FIG. 3, eight load cells 12 ...
Outputs W1 to W4 and W5 to W8 of 15 and 16 to 19
Is a load converter 100 equipped with a measurement bridge circuit and an A / D converter, and after compensating for the weight of the swing table 1 as described above, it is sampled at regular intervals and becomes a digital quantity. Then, it is sequentially loaded into the processing device 3 via the I / O interface 32. The load WT of the subject, the load center, and the load centers corresponding to the left and right feet are calculated by the arithmetic unit 31 in the processing device 3 according to the above-described formula. Then, the obtained load center corresponding to each of the left and right feet of the subject and the load center corresponding to the entire body of the subject are displayed in real time on the graphic display device 4a of the display device 4, and the time series data of the load, The time series data of the load center corresponding to each of the left and right feet of the subject and the load center corresponding to the entire body of the subject, that is, the movement trajectory, is stored in the storage device 33. The sphere detection sensor 21 stores the sphere 2 on the support 25 or the marker 70 to store these time-series data.
Data from the time when the ball 4 is detected to reset the device to the impact point where the ball detection sensor 21 detects that the ball 24 on the support 25 or the marker 70 has been hit and lost. Is stored endlessly by sequentially rewriting the oldest data into the newest data in a storage area of the storage device 33 having an appropriate storage capacity, and the data after the impact point is stored in correspondence with a predetermined time width. It is designed to be stored in another storage area having a capacity.

Along with these time series data, the load center corresponding to each of the left and right feet of the subject at the time of address, the load center corresponding to the entire body of the subject, the load center corresponding to the entire body at the body turn start point, and the top position The load center corresponding to the whole body at, the load center corresponding to the whole body at the swing-down point, the load center corresponding to the whole body at the impact point, and the load center corresponding to the whole body at the finish point are also stored in the storage device 33. Remembered. Each load center at the time of addressing is obtained by averaging the positions of the load centers before the swing start point detected as described later.

Next, a process in which the club detection sensor 22 and the arithmetic unit 31 detect the swing start point which is one of the characteristic points in the golf swing will be described. In the storage device 33, together with the above-mentioned load and load center data,
Information on whether or not the club detection sensor 22 has detected the passage of the club head is also stored in time series. Based on this stored information, the arithmetic unit 31 excludes the time of about 100 mS immediately before the impact point and sets the time when the first club detection sensor 22 detects the passage of the club head as the swing start point by tracing back the time from the impact point. To detect.

Next, a process in which the arithmetic unit 31 detects a body turn starting point which is one of the characteristic points in the golf swing will be described. Of the load and load center data obtained by the computing device 31 as described above and stored in the storage device 33, the time change of the load on the lower leg of the subject in the backswing direction shown in FIG. 4, that is, the present embodiment. Since the device configuration for a right-handed test subject is illustrated by way of example, when the load on the right foot changes with time, the search starts from the data corresponding to the swing start point indicated by point A in FIG. The position of B on the time axis is detected as the body turn start point.

Next, the process in which the arithmetic unit 31 detects the top position which is one of the characteristic points in the golf swing will be described. The component in the left-right direction, that is, the X direction, of the load-series time series data corresponding to the entire body of the subject, which is obtained by the arithmetic unit 31 as described above and stored in the storage device 33, is time-differentiated to obtain the load-center X-value. The time change of the moving speed in the direction is calculated. In the time change of the moving speed in the X direction illustrated in FIG. 5, the point F, which is traced back for a predetermined time from the data of the impact point detected by the sphere detection sensor 21 indicated by the point E in FIG. Point F indicating the reference point
The data is searched backward in the direction from, and the sign of the moving speed in the X direction first reverses from negative to positive, that is, the point G at which the direction of the moving speed in the X direction first reverses is set as the top position. To detect. The time interval from the point E indicating the impact point to the point F, which is the reference time point, is set as a top position because the direction of the moving speed may be in the backswing direction immediately before the impact point. In order to prevent detection, this time interval is preferably about 200 mS.

Next, a process in which the arithmetic unit 31 detects a swing-down point which is one of characteristic points in a golf swing will be described. Among the data obtained by the arithmetic unit 31 as described above and stored in the storage unit 33, the point indicating the top position obtained as described above in the time change 90 of the right foot load and the time change 91 of the left foot load shown in FIG. From H,
Up to a point I indicating the impact point detected by the ball detection sensor 21 corresponds to the downswing. During this downswing, within the time t from the point J, which indicates the time when the load on the left and right feet of the subject becomes equal, to the side where time elapses and t ′ to the side that goes back time, the foot on the upper hand side in the downswing direction. The rate of change of the load on the right foot, that is, the time differential value is calculated. It is suitable that both the time widths t and t'are about 50 mS. The point K indicating the time point when the absolute value of the change rate of the time change 90 of the right foot load becomes the minimum value is detected as the swing-down point.

It should be noted that 0.2 seconds after the impact point detected by the ball detection sensor 21 is detected as a finish point which is one of the characteristic points in the golf swing. Therefore, the arithmetic unit 31, the ball detection sensor 21, and the club detection sensor 22 function as a feature point detection unit S that detects a feature point on the golf swing.
