43 a case where while a user of the terminal 13 is listening to the voice mail regeneration of the voice mail is temporarily halted to record a self voice as a reply to be returned will be described for example at a point when the terminal 13 emits the voice mail data ml 1 in the address 2 of the memory 47 as a sound from the loudspeaker 43 the user starts pushing down the operation switch 46 in this case cpu 45 of the terminal 13 secures a transmission memory area in the memory 47 and as shown in fig7 stores the mail identification number m1 into a top of the transmission memory area and a reading address ad2 address indicative of a position relative to the address 1 storing the mail identification number m1 shown in fig6 of the memory 47 at the time of the pushing of the operation switch 46 into the subsequent address subsequently successively from the address next to the address storing the address ad2 of the transmission memory area of the memory 47 cpu 45 stores a voice signal which is entered via the microphone 44 by the user and digitized as the voice mail data by codec 42 until the pushing of the operation switch 46 is released here the user of the terminal 13 stores the voice mail data diametrically shown by a in fig7 a into an address next to the address storing the address ad2 of the transmission memory area of the memory 47 subsequently if the user releases the pushed operation switch 46 cpu 45 resumes the halted reading of the voice mail data stored in the memory 47 from.
