发明名称 Practice pitching apparatus
摘要 A practice pitching apparatus for identifying whether a ball pitched would be considered a strike or a ball based upon delineation of a strike area and a ball area on an upright target. The apparatus includes a frame member oriented in an upright position with a forward-facing front surface segmented into a recessed strike zone impact panel and a surrounding ball zone arrangement of impact panels. Disposed behind each impact panel is a paired arrangement of switches which are coupled to ball-counting circuitry and strike-counting circuitry. A display with a series of lights is provided for a continuously visible indication of how many balls, strikes, walks and outs have been delivered. When the third out is recorded, the entire system is reset signifying the end of an inning and the pitcher begins anew. The ball-counting circuitry and strike-counting circuitry are cooperatively arranged with respect to each other such that when the third strike is delivered, the ball count resets to zero and when the fourth ball is delivered, the strike count resets to zero. The switches are arranged such that if the ball zone impact panel is first hit, one of the two switches records the ball count and the other switch of the pair disables the strike count circuitry so that ricocheting shots will not count twice.
