A slot machine 10 includes: a photosensor 87 for detecting tokens supplied through a supply port; a RAM 153 for storing information on tokens detected as virtual tokens available in a game; a linear motion member 88 driven by a solenoid Sol to a drive position protruding outside a passage crossing a straight line part 840c from an initial position outside the straight line part 840c of a passage 840; a sensor 89 for detecting the linear motion member 88 driven to the drive position; and a warning means for warning of an abnormal condition when the linear motion member 88 driven at the drive position is not detected by the sensor 89. A timing control means for controlling timing for driving the linear motion member 88 drives the linear motion member 88 toward the drive position when no new token M is detected until a predetermined time elapses since the token M is detected by the photosensor 87.
