The communication circuit 38 of the secondary terminal 3 and the communication circuit 27 of the primary terminal 2 are communicated under control of the CPU 30, for transmission of application programs and data stored in the RAM 24 of the primary terminal 2, to the secondary terminal 3. Then the transmitted application program and data are stored in the RAM 36 of the secondary terminal 3 to form functions to be installed in the secondary terminal 3. The secondary terminal 3 is communicated with the communication circuit 27 of the primary terminal 2 to transmit data accumulated on the secondary terminal 3, to the primary terminal 2. Then the transmitted data is stored in the RAM 24 of the primary terminal 2.
