Abstract: PROBLEM TO BE SOLVED: To reduce disadvantage of a player caused by the player forgetting to execute return processing of a card or coins with respect to a game medium dispensing unit (a card reading unit).SOLUTION: In a state where an external device reads negotiable value information stored in a storage medium, a prescribed external control signal output from the external device is received by external receiving means. The external control signal is extracted by external signal extraction means. Whether or not the external device is currently reading the negotiable value information of the recording medium is discriminated by external discrimination means. On the condition that the external discrimination means discriminates that the external device is currently reading the negotiable value information of the recording medium, a game machine notifies the player to execute storage medium return processing or cancellation processing of canceling the reading of the negotiable value information. When the operation is done, a game state is changed into a specific notification mode. This configuration can thus prevent the player from forgetting to execute the return processing or the cancellation processing.SELECTED DRAWING: Figure 4
