First, the steps shown in FIG.
After turning on the power in SP1 and setting the initial state, in step SP2, either type of wood club or iron club is input. When the wood club is set, as shown in FIG. 2 in step SP3, the reference bar 12 is inserted into the end of the hosel 11 of the wood club head 10 shown in FIG. It is fixed by the knob 42. Then, the posture of the club head 10 is adjusted by manually operating the shaft rotation direction posture knob 44 so that the vertical measurement jig 52 is aligned with the sole surface of the club head 10. After the posture adjustment, the club head 10 is fixed by operating the shaft fixing knob 43.

Next, in step SP4, the measurement is started and the sole surface is adjusted. As shown in FIG. 7A, a laser beam is emitted from the displacement sensor 20 on the sole surface of the wood club 10 with reference to the shaft center of the reference rod 11, and the sole surface is scanned. E1 and E2 are detected.

In this operation, first, a command is given from the keyboard 71 so that the laser irradiation height of the displacement sensor 20 is adjusted to the reference rod 12.
The Y-axis motor 22 drives the Y-axis ball screw 23 so as to coincide with the shaft center, and the sensor mounting portion 21 is positioned in the Y-axis direction along the Y-axis linear guide 24. Next, a range for scanning the displacement sensor 20 in the X-axis direction, a sampling interval for taking in data, and a speed for scanning the laser beam are set with the keyboard 21. As a result, the X-axis motor 27 drives the X-axis ball screw 28 to move the displacement sensor 20 in the X-axis direction along the X-axis linear guide 27, and the sole surface is scanned by the laser beam. As a result, edges E1 and E2 shown in FIG. 7A are obtained.

Next, at step SP5, the correction angle of the lateral balance (lie angle direction) is calculated. That is, when a correction command is given from the keyboard 71, each of the edges E1 and E2 detected by the computer 70 and the displacement sensor 2
The distance to zero is determined. If there is a difference between the distance between each of the edges E1 and E2 and the displacement sensor 20, it is necessary to correct the lie angle, and the angle motor 45 is driven in step SP6. When the angle motor 45 shown in FIG. 2 rotates, the displacement sensor 20 and each of the edges E1 and E2
