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.

A system for automatically determining the location of a relatively small size projectile, fired from a gun and travelling at relatively high velocity, relative to a target area and for scoring the proximity of the projectile to the center of the target, the system comprising: a first rigid quadrilateral frame means having spaced parallel vertical side portions and spaced parallel upper and lower horizontal side portions for defining a polygonal open target area therebetween; said frame means comprising a first pair of two first and two second transversely extending flat side wall plate members and a second pair of two third and two fourth transversely extending flat side wall plate members arranged in a generally polygonal configuration with opposite ones of each pair of said side wall plate members being located in spaced relationship on opposite sides of said target area and being parallel to one another with an inner peripheral side surface of one of said plate members of each pair of plate members facing inwardly toward the target area and an outer peripheral side surface of one of said side plate members of each pair of plate members facing outwardly away from the target area; at least two transverse rows of a plurality of separate closely spaced light emitting means mounted on said frame means with a first row extending along a first one of said vertical side portions and a second row extending along a first one of said horizontal side portions along the periphery of the target area for providing a multiplicity of separate, individual, generally parallel light beams of non-visible limited wave length of substantially circular cross-section extending across the target area projected directly through the atmosphere without passage through any intervening separate device extending across the path of the light beam and substantially covering the entire target area and being arranged in an X-Y coordinate axis pattern; target sheet mounting means mounting on said frame means for supporting and locating a target sheet with target indicia on said frame means with the target indicia located in predetermined relationship with said X-Y coordinate pattern of light beams; at least two transverse rows of a plurality of separate closely spaced light detector means equal in number to the number of said light emitting means and being mounted on said frame means with one row extending along a second one of said vertical side portions and a second row extending along a second one of said horizontal side portions along the periphery of the target area opposite the light emitting means for normally directly receiving a generally cylindrical column of uninterrupted light directly through the atmosphere without passage through any intervening separate device extending across the path of the light beam from an associated one of the light emitting means in the absence of the presence of a projectile in the target area and for enabling each light detector means to generate a normal standard separate signal indicative of uninterrupted receipt of light from the associated light emitter means and to generate a separate interrupt signal upon passage of a projectile through the associated light beam in the target area; said parallel light beams having a diameter of less than one-half the diameter of the projectile and said light emitting means and said light detector means in each row being mounted in closely spaced laterally adjacent relationship so that at least two of said parallel light beams are interrupted and at least two of said light detector means generate a separate interrupt signal during passage of a projectile through the target area; means for receiving said interrupt signal from each of said light detector means and determining the location of each light beam interrupted by the passage of the projectile through the target area and for generating coordinate signals representative of the x coordinate and the Y coordinate of each interrupted light beam; and means for receiving and correlating the coordinate signals with prior established coordinate reference information to establish the precise location of the passage of the projectile through the target area and to generate control signals representative of such locations. The invention as defined in claim 1 and wherein: each of said light emitting means comprises only a separate generally cylindrical infrared light emitting device having a generally circular cross-section and each of said light detector means comprising only a separate generally cylindrical infrared light responsive device; and device mounting means for each row of said light emitting means and for each row of said light detector means comprising a plate member having a plurality of circular holes arranged in said pattern for receiving and supporting said light emitting and responsive devices in said pattern.
