PURPOSE:To improve the effect of communication and the range of use, by storing a plurality of messages at the same time, and performing simultaneously reproduction while keeping the relation of time among a plurality of messages. CONSTITUTION:A message A is transmitted to a significant information detectig circuit 41 and a message B is transmitted to a significant information detecting circuit 42 via channels 21 and 22 from a terminal device 11. A building block part 411 of the circuit 41 stores one period's share of sound information EA or a nonsignificance information IA of the message A in synchronizing with the serial number RN for storage applied from a serial number controlling circuit 5 to constitute an information block A(RN) and transmits it to a detection section 412. The section 412 monitors whether or not the sound information EA exists at each information block A(RN), and the information block only existing in the information EA is transmitted to a serial addition section 413. The section 413 adds the RN corresponding to the received information block to constitute significant information blocks EA RN, which are sequentially stored in a storage circuit 7 via a buffer 61. The message B is similarly stored in a storage circuit 7 sequentially. |
