This invention suppresses increase in power consumption and reduces the time it takes until a controller is usable when starting the operation of console main unit from the standby state by the controller through BT communication. When a console main unit 10 is started up from the standby state by a controller through BT communication, a main CPU 64 of the console main unit 10 reads in and runs a controller connection managing program after the BT driver is read-in and run. Upon reception of a logical layer connection request signal from the controller, the main CPU 64 stores that logical layer connection request signal in main memory 65, reads in and runs the controller connection managing program, reads in terminal identification information from the main memory 65, establishes a logical layer connection through BT communication, and makes a communication module 79 transmit a logical layer connection enable signal.
