发明名称 Baseball pitching practice target
摘要 A baseball pitching practice device comprising a support frame to which is independently supported a plurality of panel members disposed side-by-side and forming a target area. Each of the panels has a designated segment portion of the target area. The target area includes a central strike zone area delimited by some of the panel members. One or more normally-open electrical contacts are associated with each of the panels and closable upon the application of an impact force on an outer surface of its associated panel. A display device is provided to identify which panel has been subjected to an impact force. A visual display identifies the panel having been impacted and also provides a numerical read-out of a total numerical value with each of the panels having independent numerical values.
