PURPOSE:To provide a totalizator device which can confirm that the operation information has been received through a terminal without deteriorating the selling efficiency. CONSTITUTION:A controller 11 is provided with a simultaneous transmitter means 29 which transmits simultaneously the operation information to the terminals 12A-12N, and a transmission/reception control means 34A which transmits successively the answer confirmation signals to the terminal 12A-12N after the simultaneous transmission of the operation information and then receives the answer signals from those terminals respectively. Meanwhile a transmission controller 23A is added to each of terminals 12A-12N to transmit the acknowledge signal against the answer confirmation signal after the operation information is received from the controller 11. |
