CA 2051038
The apparatus of the invention comprises a backboard; a matrix of panels representing a strike zone; springs for resiliently biasing each of the panels outwardly from the backboard; switches mounted to the backboard behind the panels, whereby the impact of a pitched ball will move the panel inwardly towards the backboard causing the switch to momentarily close; a horizontal array of red, yellow and green lamps mounted to the backboard adjacent the top of the backboard, one lamp in vertical alignment with each of the columns of panels; a left vertical array of red, yellow and green lamps mounted to the backboard adjacent the left edge of the backboard, one lamp in horizontal alignment with each row of panels; a right vertical array of red, yellow and green lamps mounted to the backboard adjacent the right edge of the backboard; a power source; and electrical wiring to connect the power source, switches and lamps. When a baseball hits a left or right side panel the lamp in vertical alignment with the panel and the lamp horizontally adjacent the panel will light. If a center panel is hit, the lamp in vertical alignment with the panel will light and both lamps in horizontal alignment with the panel will light.
