Abstract

An automatic target shooting system for determining projectile location relative to a target, calculating a score based upon the location, and displaying a replica of the target with an indication of the location of the projectile relative to the target and the score. A target support structure defines a target area with criss-crossing X-Y-type coordinate light beams extending thereacross between light emitter devices and light receiving devices which generate output signals indicative of the location of a projectile during passage through the target area. The output signals are utilized by a computer device to identify the location of the projectile relative to the target, and to score the shot in accordance with the location. A replica of the target is displayed on a CRT screen with an indication of the location of the shot thereon and the score for the shot.
