A storage interface unit can exchange player's individual information with an external storage device placed on a gaming machine. An individual information manager unit uses the individual information in player identification or as credits. A game control unit executes a game program and thereby conducts a game. An alarm unit monitors the connection between the storage interface unit and the storage device, or the presence or absence of the storage device on the gaming machine. The alarm unit outputs a warning message or signal indicating that the storage device is still positioned where it can communicate with the storage interface unit. The warning message or signal is outputted, for example, when the game control unit has received from the player the instruction to convert his/her credits into cash or monetary information to be stored in the storage device, or when the player's credits have been reduced to zero. |
