PROBLEM TO BE SOLVED: To provide a game machine where taking out of tokens from a cup is suppressed even when a player leaves the machine in the middle of a game. SOLUTION: The game machine is provided with: an upper speaker for reporting stealing of a token C based on detection by a photoelectric sensor 28 which detects stealing of the token C in the coin cup 26; and a sub-controller for controlling the upper speaker. The sensor 28 consists of: a plurality of light emitting parts 29 installed at one side part of the coin cup 26 and forming a line in a vertical direction; and a plurality of light receiving parts 30 which are installed at the other side part of the coin cup 26, forming a line in the vertical direction, and receiving infrared rays I irradiated from the light emitting parts 29. The sub-controller realizes: a function of storing the height of reserved token C based on the variation of the number of light receivings at the plurality of light receiving parts 30; a function of judging whether the number of light receivings of the plurality of light receiving parts 30 positioned above the height of the stored token C is varied; and a function of making the upper speaker operate in the case of judging that the number of light receivings of the plurality of light receiving parts 30 is varied.
