Abstract
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.
