PURPOSE:To prevent tone ringer sounds from being mixed into sound recording voice by not only disconnecting a tone ringer circuit from a line but also connecting a ringing tone detecting circuit to the line during input and sound recording of voice and displaying an incoming not aurally but visually in case of the telephone incoming during sound recording. CONSTITUTION:In case that voice is inputted from an input device 15 and is sound recorded, and input start is inputted by operating an input part 24, and an input path of a digital sound converting part 11 is connected from the input device 15 to a processor part 8 through a digital encoding part 12, and a switch 28 of a communication line interface 17 is switched to the side of a CI detecting circuit 29 to disconnect a tone ringer circuit 27 from the line. Thereafter, an input routine is started to start the voice input, and voice is sound recorded in a storage part 22 as digital sound data. If an incoming interrupt occurs by a call from an exchange in this state, the CI detecting circuit 29 is operated in response to the ringing tone to input an interrupt signal to the processor part 18 through an output line 32. The processor part 18 receives the interrupt signal and lights a lamp to display the incoming. |
