PROBLEM TO BE SOLVED: To provide a game machine capable of quickly and accurately detecting an illegal act on a selector.SOLUTION: A game machine includes a selector that has a first supplied token passage detecting sensor and a second supplied token passage detecting sensor disposed at a predetermined distance along a token passage through which tokens M supplied from a token supply port pass. In an MPU, a total time measuring timer measures the total time from the start of a shielding state of the first supplied token passage detecting sensor with a token M at a timing t1 until the end of the shielding state of an optical path of the second supplied token passage detecting sensor with a token M which comes after a predetermined number of tokens. Measurement of the total time is terminated when the passing intervals of adjacent tokens M exceeds a passing reference time. Token passage determination for comparing the total time with the reference time can be quickly entered, thereby accurately detecting an illegal act on a selector. |
