<p>A device for shooting and returning of a playing ball in a playing roulette, preferentially the electronic one, is executed of an assembly (1) for shooting a ball (8) and of an assembly (2) for returning the ball (8) into the assembly (1), where both assemblies are mounted close to and within a roulette cylinder (3) and are connected to each other so that they enable traveling of the ball (8) in the closed circle between several consecutive games, and where the complete operating of the ball (8) is guided automatically by a controlling computer (13) which is a component of the roulette. The assembly (1) for shooting the ball (8) is executed in the sense of a centrifugal pressure device (5) with a rotor (6) wearing at least one branch, but preferentially two branches, where an entry opening (7) is executed - within the lower part of the device (5) from the one side - for the playing ball (8) which returns from the assembly (2), to receive the ball (8) preferably into the lowest point of the interior of the assembly (1), from where the rotor (6) accelerates it along a circular groove (9) within the rotor (6) and lets it fly out through a tube (10) in the tangential direction with regard to the wall (11) of the cylinder (3). The assembly (2) is designed so that each nest (A) for the reception of the ball (8) is fitted with an exit (20) in its bottom or its exterior circular wall to enable automatic movement of the ball (8) out of it through other parts of the assembly (2) into the assembly (1), with the ball (8) transition time through the exit (20) being controlled by a shutter (21) which is opening exits (20) in a controlled way and is operated by the controlling computer.</p> |
