A transmission prohibition control section 12 prohibits a transmission section 10 from transmitting a communication radio wave in response to a command of the user, etc. When transmitting a communication radio wave is prohibited, a central control section 11 displays the fact that a communication radio wave is prohibited on first and second communication mode display sections 2a and 2b in such a manner that outsiders can also check it. Further, while transmitting a communication radio wave is prohibited, the central control section 11 accepts and executes any other function than a communication function, selected by the user, etc. A preset function of presetting a function to be executed after the prohibition of transmitting a communication radio wave is released is provided.
