CLAY SHOOTING SIMULATION SYSTEM BACKGROUND OF THE INVENTION The present invention relates to a clay shooting simulation system suitable to use in the training of the clay shooting or for the amusement purpose.

Several kinds of indoor type such systems have been known and one of them which has been developed most recently utilizes a light-emittingtype gun and a clay pigeon provided with a light responsive element. In this system, the clay pigeon is actually discharged and the shooter sights the clay pigeon. Since the light responsive element is provided in the clay, the hitting occurs when the light beam from the gun enters the light responsive element. Therefore, the lead-sighting which must be required in the actual clay shooting can not be simulated by this system. Furthermore, since the clay pigeon flies actually, the recovery thereof is required.

The present invention intended to provide a novel clay shooting simulation system which can simulate the actual clay shooting almost completely.

SUMMARY OF THE INVENTION The present invention comprises, in combination, a screen, at least a first projector adapted to project a visible light mark to be focussed on thescreen, at least a second projector adapted to project an invisible mark tobe focussed on the same screen, at least one mirror means adapted to reflect the two marks projected by the first and second projectors respectively to the screen, at least one means for providing continuous movements of the mirror means and the second projector with a specific continuous relative movement between the two rnarks on the screen such that the visible mark moves along a locus simulating an actual flying locus of a clay pigeon and the invisible mark always exists at a position leading the visible mark so that the invisible mark simulates a lead-sighting point with respect to the visible mark, at least one light-receiving type gun adapted to receive a light beam reflected from the invisible mark on the screen and means responsive to a receiption of the light beam by the gun for informing the hitting to an operator.

DETAILED DESCRIPTION OF THE INVENTION Returning to the drawings, an embodiment of the present invention will now be explained.

FIG. 1 is a schematic illustration of a laser clay shooting simulation system according to the present invention and FIG.2 is a plane view of the system in FIG. 1. In general, a scene in a landscape is projected onto a screen 4 by a suitable projector 6 disposed behind of the screen 4 or by a projector 6 disposed in front of the screen 4, if necessary. On the same screen 4, a visible target mark A is also projected through a mirror 8 at which a clay shooter looks. Further, an invisible real target mark B is projected onto the same screen 4 in the similar manner. The visible imaginary target mark A and the invisible real target mark B are made to move on the screen 4 with a special interrelation therebetween in such a manner that they simulate an actual flying locus of a clay pigeon in the clay shooting area. The special interrelation between the marks A and B are provided by a special relative movements of the mirror 8 and the

projectors

2A and 2B associated with the respective marks A and B. When the shooter who has been recognizing the imaginary mark A moving on the screen 4 makes a correct over-sighting or lead-sighting with a receiving-light type gun 10, the muzzle of the gun will be directed to the real mark B and a light beam reflected from the mark B on the screen 4 is received by the gun through the muzzle thereof. At that instance, if a trigger of the gun is operated by the shooter, a light receiving means housed in the gun 10 is actuated. Upon the actuation of the light receiving means an electric receiver 12 and a control circuit are actu-
