PROBLEM TO BE SOLVED: To provide a device which detects wrongdoing on a token selector and does not cause a trouble of getting stuck of tokens or the like. SOLUTION: The device detects the wrongdoing by monitoring the token selector in accordance with an operation of a blocker. Here, only a second token-counting sensor provided on a downstream side is monitored, so that the token thrown in during the blocker operation is not wrongly determined as the wrongdoing. A token-counting sensor on an upstream side is not monitored. Furthermore, an error determination is not performed within a fixed time after starting up of the blocker, thereby engulfing of the tokens is not wrongly determined as a wrongdoing.
