PROBLEM TO BE SOLVED: To prevent such misdetermination that a push-order mistake occurs through a mere operation-timing lag despite an appropriate push-order stop operation.SOLUTION: A slot machine includes a plurality of reels, motors for each reel, a starting lever switch and a control device. The control device sets an invalid period A in which a stop operation by each stop button switch at reel motor starting is invalid and, when the invalid period A passes, shifts it to a valid period in which a stop operation by each stop button switch is valid. When a stop operation is conducted by the stop button switch during the invalid period A, a forcedly invalid state is set for a stop operation to be forcedly invalid by the stop button switch conducted during the valid period immediately after the invalid period A passes. The forcedly invalid state is released when the stop operations by the stop button switch during the valid period reach a predetermined number of times. |
