Frequency responsive light target
First Claim
1. A simulated target-shooting apparatus having a light source adapted to be projected upon a screen and a means within a simulated gun adapted to receive a light signal projected upon the screen from the light source, comprising a. a target screen, b. a target image adapted to be projected by the light source upon said target screen and emitting a modulated signal having a preset frequency upon said target screen, c. a photo-electric cell contained in a simulated gun and adapted to be directed upon said screen to receive said modulated signal and to be activated thereby, d. a detector means in circuit with said photo-electric cell and receiving therefrom a signal pulse identical to said preset frequency modulated signal projected from said signal source onto said screen and received by said photo-electric cell, e. and a hit target indicator in circuit with said detector means and adapted to be energized by a signal pulse from said detector means when the latter receives a signal pulse from said photo-electric cell so as to interrupt said light signal to indicate a target hit upon said target screen, f. said hit target indicator including a movable plate having target-image-forming orifices therein, with said plate intercepting a modulated light signal emitted from the target image for projecting upon the screen different target images.

Abstract
A simulated target shooting apparatus comprising a source of modulated light having a pre-set frequency. The light takes the form of a target image. A weapon facsimile is provided which cooperates with a receiving device comprising a photocell and a detector adapted to select one one of the different signals sentout by said photocell when hit by light rays. The signals so generated are forwarded to supply a hit target indicating signal.
