PROBLEM TO BE SOLVED: To prevent a fraudulent action (cheating by the use of a credit increasing gadget) on a slot machine. SOLUTION: When the result of token counting based on the output of a token sensor of a token selector of the slot machine exceeds a predetermined upper limit, a blocker is operated and a timer is activated simultaneously. After the blocker is operated, the output of the token sensor is monitored, and the output of the timer is acquired when output is generated in the token sensor. When the acquired output of the timer exceeds a predetermined threshold, a fraudulent action is determined. When the output of the timer does not exceed the predetermined threshold, token swallow is determined and the fraudulent action is not determined. COPYRIGHT: (C)2010,JPO&INPIT |
