PROBLEM TO BE SOLVED: To allow possibility of illegality which is not undeniably concluded to be confirmed from an outer part. SOLUTION: A setting value for determining the winning probability of an internal lottery is changed by operating a setting switch 91. After a front surface door is opened, it is required to allow a setting key switch 92 to be in an unlock state and a main switch 94 to be turned on, in order to change the setting value. The series of operations has the possibility of illegality even when illegality is not concluded. The detection signals of a door opening sensor 85, the setting switch 91, the setting key switch 92, and the main switch 94 are outputted even to an outer output board 105. When a prescribed error state is generated due to the operation defect/fault of a slot machine, the control part 110 of a game control board 101 outputs a prescribed error signal to the outer output board 105 since the possibility owing to the illegal operation exists. when the possibility exists in the case of no conclusion of the illegal operation, an illegality possibility signal is outputted from an outer output terminal 152.
