A ball drawing apparatus for drawing a series of balls at random includes a transport arrangement (10) for receiving the series of balls (15) and positioning each ball in a reading position. Each ball (15) includes a transponder (46) which is adapted to transmit an identifying signal when energized by an energizing signal. The identifying signal may be used to identify the particular ball (15) and provide a number or other symbol which is printed on the ball. A reader unit (12) includes a transmitter/receiver (41) and antenna (25) combination which transmits the energizing signal to each ball (15) as the respective ball passes through the reading position, and then receives the resulting identifying signal transmitted from the respective ball transponder (46). The transmitter/receiver (41) communicates the identifying signal to a control system (14) which displays the symbol of the identified ball. Control system (14) controls the operation of all elements of the ball drawing apparatus.

Ce dispositif de tirage au sort de boules comprend un agencement de transport (10) destiné à recevoir une série de boules (15) et à placer chaque boule dans une position permettant une lecture de celle-ci. Chaque boule (15) comprend un réémetteur (46) conçu pour émettre un signal d'identification lorsqu'il est excité par un signal de charge. Il est possible d'utiliser le signal d'identification pour identifier la boule en particulier (15) et fournir un nombre ou un autre symbole imprimé sur la boule. Une unité de lecture (12) comprend un émetteur/récepteur (41) ainsi qu'une combinaison d'antennes (25) transmettant le signal à chaque boule (15) lorsque la boule passe à travers la position le lecture, puis elle reçoit le signal d'identification résultant, émis à partir du réémetteur (46) de la boule correspondante. L'émetteur/récepteur (46) communique le signal d'identification à un système de commande (14), lequel affiche le symbole de la boule identifiée et commande le fonctionnement de tous les éléments du dispositif de tirage au sort de boules.
