PROBLEM TO BE SOLVED: To utilize a telephone set for killing waiting time or the like by an owner and the friends and to prevent influence on a telephone function by not making the response of an input means relating to communication other than a key taking part in ending a specified mode by the selection of the specified mode. SOLUTION: By pressing a function selection key F for two times, a control circuit 7 selects the specified mode using a display means, the input means and a sound generation means, etc., not taking part in a communication means and displays a specified mode name. The specified mode is a mode for using a game function or a function capable of generating non-musical special sound such as simulation sound and surprising sound, etc., for instance usable for killing the waiting time or the like and deepening friendship. At the time of being in the specified mode, since the mode cannot be directly ended, the control circuit 7 does not make the response of the input means 10 relating to the communication other than a dial key 10b and the key taking part in ending the specified mode.
