PURPOSE:To Provide a device for simulating a flash light from a gun port of a model gun by a method wherein some flash images illuminated in sequence at a light emitting surface from an operator's side are expanded as an enlarged flash imaginary image by a light collecting means and the enlarged imaginary image is synthesized on a far background scene by an optical synthesizing means such as a half-mirror or the like. CONSTITUTION:When a light emitting surface 11 of a transparent resin plate is coincided with a line connecting a focal point F1 of a convex Fresnel lens 8 with one point P at a circumference, an enlarged imaginary image B at the light emitting surface 11 appears in parallel with an optical axis OQ of the lens 8. A launching trigger 3a of a model laser beam gun % 1 is pushed, thereby the lamps are lit in sequence from a light source 13 by a lighting circuit along with a launching sound. As the imaginary image B of the light emitting surface 11 coming through the lens 8 is synthesized with light passing through a half-mirror 7, the imaginary image B can be seen as a laser beam 6 generated from a gun port 5. In this case, if an image displaying device is applied at an intermediate bottom surface 10, a flash light from the laser beam 6 can be seen to be floated out of a ground when an orientation of the gun is in its horizontal position. |
