PROBLEM TO BE SOLVED: To provide a slot machine capable of accurately detecting abnormality even if flow time of a token from a detection means at an upstream side to a detection means at a downstream side varies.SOLUTION: It is determined that a casting error has occurred if the number of times of detection of passage of a token through a slot sensor 170 after the token is cast reaches the number of tokens (7 in this embodiment) that is equal to or more than the number of tokens spread all over in the meantime when a chute sensor 166 does not detect the passage of the token and tokens are spread all over on a flow path from a position of the slot sensor 170 to a movable piece 163 for detecting the passage of the token by the chute sensor 166. |
