Abstract
Abstract A game comprising a toy gun and an electronic target which registers hits produced by the gun. The gun comprises an electronic flash tube connected to a circuit to produce a high voltage unidirectional supply from a low voltage supply. When the gun trigger is depressed, the flash tube is fired and the resulting light is concentrated to produce a relatively narrow beam of light. As well, an audio signal is produced for each press of the trigger. If the beam of light impinges on the electronic target, an audio-visual signal results to indicate a hit.

Claim 1
Independent Claim
104 words
A game comprising a toy gun, including an electronic flash tube; means to provide a relatively low-voltage direct current supply; means to produce from the low-voltage supply a relatively high-voltage unidirectional supply; means coupled to the high-voltage supply to fire the flash tube in response to pressure on a trigger of the gun; and a reflector positioned adjacent the flash tube to produce a beam of light; and a hollow concentrator having a relatively large diameter inlet into which the beam passes, and a relatively small diameter outlet which serves to concentrate the beam into a relatively narrow beam for projection at a target.
