ABSTRACT:
A pitching practice apparatus includes a frame unit having a rectangular frame member, X-axis and Y-axis sensor units mounted on the frame member, a control unit connected to the sensor units and to a sound generating device, and a net body provided on the frame unit. The sensor units are operable so as to form sampling regions for sensing entry of a ball into the frame member. The control unit determines position of the ball entering into the frame member, and compares the ball position with preset parameters to determine whether the ball is a good ball or a foul ball. Ball information determined by the control unit is shown on a display device. The sound generating device is used to generate a sound output corresponding to status of the ball that was thrown into the frame member as determined by the control unit.
