To prevent fraudulence (fraudulence by using electric waves) intending to extract more game balls than a prescribed number by making a pay-out counting switch inside a ball pay-out device malfunction with electric waves and canceling the operation of the switch thereby.
Stop of the pay-out motion is determined during the pay-out motion (S7). Accordingly, the pay-out motion can be stopped more quickly than before when the fraudulence is performed by always comparing the number of times of detection of game balls by a put-out counting sensor with the number of fed balls by a sprocket and confirming the difference (error) based on the comparison. As a result, the number of game balls to be fraudulently paid out can be reduced as much as possible.
