BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring and analyzing a batter's posture on an inclined scaffold in an approach shot performed toward a green in golf play and a movement of a golf ball at the time of ball shot.

[0002]

2. Description of the Related Art As an apparatus for practicing an approach on a real course by incorporating a simulation apparatus into the practice of approach shots of golf, for example, a golf apparatus for shooting a golf ball set on a flat shot mat is used. The movement of the club head and the speed, spin rate, and launch angle of the hit ball are measured with a sensor or high-speed shutter camera, converted into numerical data by an analyzer, and the carry and trajectory of the hit ball are displayed on a video screen. Golf simulation device is disclosed in
-4887. Further, a golf ball movement measuring method is disclosed in JP-A-10-186474. Japanese Patent Application Laid-Open No. 4-200766 discloses an inclined golf tee gland in which the turn of the table and the inclination of the table are set by a screw type jack using a circular turntable. Further, a hitting device for golf practice in which the hitting plate is tilted by the front and rear tilting means and the left and right tilting means is disclosed in Japanese Patent Application Laid-Open No. Hei 5-261170, in which various tilts are reproduced by a tilting turntable which can set a tilt angle in one direction. A golf practice table with a turntable for practicing golf shots is disclosed in Japanese Patent Application Laid-Open No. 8-299519. As described above, various movable tilt type golf practice tables and golf ball motion measuring methods are individually disclosed.

[0003]

In the prior art, for example, the above-described ball movement measuring method at the time of a golf shot is described as follows.
It mainly performs measurement analysis at the time of a golf shot on a flat tee-up ground, and analyzes and diagnoses the relationship between the batter's swing and the golf club to provide advice and guidance, select an appropriate club, and determine the part number. Its main purpose is to: When playing on the actual golf course, the player plays the hole-in goal toward the green, and particularly in the approach shot performed toward the green, the scaffold to be addressed is a scaffold inclined forward, backward, left and right, and is unstable. The reality is that approach shots are taken in an address position. Therefore, in practice at the practice area, a bat table that can be tilted freely is installed in order to make the swing scaffold closer to the actual situation, and the movement of the shot is measured and analyzed in combination with the shot with this freely inclined type bat table. He analyzes the relationship between the line of movement of the swing and the position of the club. By the way, in practicing a shot, in addition to these analyzes, it is necessary to practice while checking the direction in which the shot ball protrudes, the carry and the trajectory, that is, the bend. When using the movable tilting golf practice platform shown in the above-described prior art as a simulated scaffold of an actual golf course, the entire bat plate turns or the center of the bat plate tilts with the support point as a support point.・ It is made to turn. Therefore, the shot mat for teeing up the golf ball in the practice table with such a turn at bat plate greatly fluctuates in position. For this reason, a ball motion measuring device such as a sensor or a camera moves or the relative position fluctuates, so that accurate measurement is difficult, and there is a problem that a shot cannot be analyzed and displayed.
