To provide a game machine capable of easily finding a fraudulent act.

In the Pachinko machine 10, when both an inner frame 12 and a front frame 14 are closed, notification by the emission of light is executed with each of illumination parts 29-33 and a display lamp 34 for the predetermined period of 30s after the closing. Thus, even if at least either of the inner frame 12 or the front frame 14 is opened, for instance, the fraudulent act is performed, and then the opened inner frame 12 or the front frame 14 is closed in a short time, it can be notified that the closed inner frame 12 or the front frame 14 has been opened previously by the emission of the light for 30s after the closing. Accordingly, the fraudulent act performed to the Pachinko machine 10 can easily be found.
