5, based on the required input signal from the second sensor 39,
According to the program stored in the ROM 51, the cursor moving unit 52, the CRT display unit 15, the first motor 17, the second motor
The motor 19 is driven and controlled, and the RAM 53 is arbitrarily and variously set by the mouse 14 as a setting means.
The storage means stores speed distribution data of the arm 4 and rotation angle distribution data of the second arm 5.

Here, the above-mentioned CPU 50 also serves as control means for driving and controlling the first motor and the second motor 19 based on the stored contents of the RAM 53 as a storage means. Input setting using the above-described personal computer 12 in the golf ball trial hitting machine configured as described above will be described.

First, the power of the personal computer 12 is turned on to drive the CRT display unit 15, and a grid line image (image in a state where no curve is drawn in FIG. 7) is displayed in the first area E1 and the second area E2. ) Is displayed.

In the grid line image of the first area E1, the horizontal axis shows the rotation angle of the first arm 4 from 0 degree (see FIG. 3) to 360 degrees (see FIG. 5), and the vertical axis shows the first arm 4 of the first arm 4. It is an image that takes a speed from zero to the maximum (in other words, the drive speed of the first motor 17), and the grid line image of the second area E2 is 0 degrees to 360 degrees of the first arm 4 on the horizontal axis. Up to the second arm 5 on the vertical axis.
