Abstract
Abstract A shooting game apparatus to project a target and a pair of bullets on a screen. Upon firing a gun, a pair of bullets will move on the screen toward the target giving a feeling of real air fights. The apparatus comprises a housing, a light source disposed in the house, a pair of bullet forming units placed in the sides of said light source in a symmetrical fashion including a bullet slit, a mirror and a lense, said units being rotatable around said light source in said housing, and a means for driving said units rotating around said light source, whereby a pair of bullets are projected and moved on a screen in a symmetrical fashion.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
86 words
A bullet image projecting device comprising: a housing: a light source disposed in said housing; a pair of bullet image forming units placed at generally opposing sides of said light source in a symmetrical fashion, each unit including a bullet slit, a mirror and a lense, said unit being rotatable around said light source in said housing, and a means for rotating said unit cojointly around said light source, whereby a pair of bullet image are projected and moved on a screen in a symmetrical fashion.
Claim 2
Dependent Claim
86 words
A bullet image projecting device comprising: a housing: a light source disposed in said housing; a pair of bullet image forming units placed at generally opposing sides of said light source in a symmetrical fashion, each unit including a bullet slit, a mirror and a lense, said unit being rotatable around said light source in said housing, and a means for rotating said unit cojointly around said light source, whereby a pair of bullet image are projected and moved on a screen in a symmetrical fashion.
Claim 3
Dependent Claim
129 words
A bullet image projecting device comprising, a housing, a light source disposed in said housing, a pair of bullet image forming units placed at generally opposing sides of said light source in a symmetrical fashion, each unit including a bullet slit, a mirror and a lense, said unit being rotatable around said light source in said housing and a means for rotating said units cojointly around said light source, wherein imaginary extensions of supporting shafts for each one of said units cross each other at the center of said light source, and beam lines from each one of said units cross each other at the center of rotation of said units, thereby providing horizontal and vertical motion factors to tracks of the bullet images as projected on said screen.
Claim 4
Dependent Claim
129 words
A bullet image projecting device comprising, a housing, a light source disposed in said housing, a pair of bullet image forming units placed at generally opposing sides of said light source in a symmetrical fashion, each unit including a bullet slit, a mirror and a lense, said unit being rotatable around said light source in said housing and a means for rotating said units cojointly around said light source, wherein imaginary extensions of supporting shafts for each one of said units cross each other at the center of said light source, and beam lines from each one of said units cross each other at the center of rotation of said units, thereby providing horizontal and vertical motion factors to tracks of the bullet images as projected on said screen.
Claim 5
Dependent Claim
81 words
A bullet image projecting device according to claim 1 or 2 wherein said means is so arranged that a crank shaft to be rotated by a driving unit and a working part of a crank to rotate said bullet image forming units with one end thereof are pivotally connected to each other at around an upper dead point of the rotation of said crank when bullet images disappear, thereby causing the bullet images to have the slowest speed before their disappearance.
