Abstract
A light shooting apparatus for amusement including a target structure with a photoelectric sensitive element and a light emitting gun, whereby, upon a successful shooting, a light beam enters into the photoelectric sensitive element from which a signal is generated to effectuate a control circuit so as to cause the target structure to fall down and display a "hit". The target structure comprises; a target assembly including at least one supporting segment and at least one target object, said supporting segment having longitudinal through-hole through which a rope is passed and said target object being provided with a photoelectric sensitive element, whereby the target object takes a standing position when the rope is in a tight state but takes a fell-down position when the rope is loosened; a rope pulling device which keeps a rope tight; and a control device for controlling said rope pulling device, whereby the rope is loosened in response to an output signal from the photoelectric sensitive element of the target segment.
