1. A moving target practice range for simulating the firing of a gun using projected light on a screen comprising:

  • a source of power;

    projector apparatus connected to said source of power;

    light means inside said projector apparatus receiving voltage from said source of power;

    first reflector means inside said projector apparatus for reflecting at least a portion of illumination from said light means approximately perpendicular to said screen;

    cam means driven by a motor means connected to said source of power, said cam means being operatively connected to said first reflector means to cause a substantially constant velocity sweep of said reflected illumination on said screen upon oscillation of said first reflector means by said cam means;

    gun means connected to said projector apparatus for receiving adjustments therefrom, said gun means having flash means therein connected to said source of power and trigger means of said gun means for generating a flash of light upon pulling of said trigger means;

    second reflector means in said gun means for reflecting said flash of light in approximately the same direction said gun means is pointed;

    manual adjustment means varies adjustment voltages received by vertical positioning means and horizontal positioning means, said vertical positioning means moving said second reflector means in response to said adjustment voltages to compensate for said drop, and said horizontal positioning means moving said said reflector means in response to said adjustment voltages to compensate for said lead;

    projector apparatus having automatic adjustment means connected to said cam means for varying therewith to change said adjustment from said projector apparatus to said gun means in response to angle of said reflected illumination to said screen, said adjustment changing said lead and said drop in response to said angle;

    vertical positioning means comprises a vertical solenoid means connected to a horizontal axis of a second mirror of said second reflector means, and said horizontal positioning means is a horizontal solenoid means connected to a vertical axis of said second mirror;

    manual adjustment means is located in said projector apparatus for varying said adjustment therefrom to said vertical solenoid means and horizontal solenoid means;

    automatic adjustment means are variable resistors operatively connected to said cam means, said variable resistors providing said adjustment voltage to said vertical solenoid means and said horizontal solenoid means to automatically compensate for said lead and said drop caused by increased distance to the reflected illumination as said angle changes.
