ABSTRACT:
My invention comprises a ballistic impact printer which includes a gun for successively propelling balls to a printing medium spaced from the gun. The balls are fed to the printer from a reservoir and recycled to the reservoir after they have performed their impact-printing function. I provide a bleeder duct for the projectiles intermediate the projectile feeder and the gun. When no printing occurs, the balls are deflected to the bleeder duct and never reach the gun. When printing is desired, the bleeder duct is blocked in order to constrain the projectiles to be fed to the gun, past a deflector which normally diverts the projectiles to the bleeder duct. The gate is a rapidly acting, electrically actuated assembly employing a piezo crystal or crystals, an electromagnet, or a solenoid. The deflector is positioned in the feeding duct and may be spring-loaded so it will yield when the gate is closed.
