PROBLEM TO BE SOLVED: To enable a player to make emergency communication with a management building by voices with simple manipulation. SOLUTION: When the player depresses a button 2 for emergency communication in order to make emergency communication with the management building, emergency communication permission information is transmitted via a repeater from a radio circuit 22 for data communication to the management building. When a signal for controlling the transmission/reception mode of a voice transceiver circuit 12 is detected in the information signal from the management building, the control of the transmission and reception of the voice transceiver circuit 12 is executed by a control section 11 for emergency communication. As a result, the player is able to transmit the contents of the emergency communication with voices to the management building via the voice transceiver circuit 12 and to listen to the response from the management building through a speaker 5. |
