Further, the control portion 2 causes a simulative incoming call operation detecting means to detect operation to instruct a simulative incoming call by a user, and causes an incoming call sound starting means to start an incoming call sound for crime prevention. Further, the control portion 2 causes a simulative response operation detecting means to detect operation to respond to a simulative incoming call by the user, and causes a simulative telephone conversation starting means to stop the incoming call sound for crime prevention.
