Title:
GOLF BALL DRIVE ANGLE MEASURING DEVICE
Document Type and Number:
Japanese Patent JPH09140835
Kind Code:
A
Abstract:

To provide a golf ball drive angle measuring device capable of measuring the drive angle with high accuracy.

When a ball A driven toward the center of the lateral direction of a support frame 3 passes through the support frame 3, the passing position of the ball A in the support frame 3 is detected by a lateral direction sensor 1 and a vertical direction sensor 2. The vertical direction sensor 2 located at the same height position as the driving position of the ball A is set to an origin Y0 in the vertical direction, the lateral direction sensor 1 located at the center in the lateral direction is set to an origin X0 in the lateral direction, then the drive angle θ1 of the ball A in the lateral direction and the drive angle θ2 in the vertical direction are calculated based on the position (Xn, Yn) where the ball A actually passes and the distance Z1 from the driving position of the ball A to the support frame 3.
