Abstract (en)
[origin: EP0271365A2] An apparatus and method for selecting random numbers. A stream of air provided from a fan beneath the chamber propels balls through a tubular display arrangement and back into the chamber. A first tube section extends from the chamber and is connected to a second tube section which is partially transparent, perforated and extends generally parallel to the top surface of the chamber. A third tube section extends from the first tube section and returns to the chamber. The balls are retained in the generally parallel tube section by a retaining means which, when released, allows the balls to be carried back into the chamber.
