ABSTRACT:
In a batting practice range where a pitching machine is installed to automatically pitch a ball toward a batter's box, hitting zones such as out zones, hit zones and home run zones are provided in front of the batter's box to detect a ball driven into either one of them from the batter's box for judging the ball as "Out", "Hit" or "Home run". An upright board is installed behind the batter's box and provided with a strike sensor for detecting vibration caused by a ball pitched by the pitching machine and struck the upright board and for judging the ball as "Strike". If a ball pitched by the pitching machine is not detected as any one of "Out", "Hit", "Home run" or "Strike" within a predetermined time, the ball is Judged as a foul ball.
