PROBLEM TO BE SOLVED: To make a telephone call from a separated place without directly operating a portable telephone set or a simple portable telephone set. SOLUTION: When an incoming call is received by a portable telephone set/simple portable telephone set, a talking signal is transmitted from a talking controller (S2). At the time of receiving the talking signal, a talking device drives a vibrator and turns on/off an incoming lamp to inform a user of the reception of the incoming call (S10). When the user depresses a talking switch of the talking device, the talking device transmits a talking signal (S13) and is turned to a talking state (S14). The talking controller receives the talking signal and inputs a talking control signal to the portable telephone set/simple portable telephone set through an interface (S4) to set up a talking state (S5). |
