PURPOSE:To attain effective use of a memory in a device at reception side by transferring information when it is information to be stored to a secondary storage device according to a predetermined protocol so as to allow the device at reception side to store it without assembling. CONSTITUTION:An information unit IU transferred from an input data line to a transmission buffer 8 is decomposed by a transport unit TU and transferred to a communication processing device 5. When the transmitted TU is processed after it is assembled into the IU at the device at reception side, an IU assembling display is set and then the TU is transferred to a TU transmission device 9. The TU transferred to the TU reception device 12 is discriminated for whether or not the IU assembling display is set by a display discrimination device 18 and when it is set, the TU is transferred to a reception buffer 14 and transferred to IU information processing device 15 after the TU is assembled into the IU. When the display is not set yet, the TU is transferred directly to the secondary device 16, where the TU is assembled into the IU and only the information required for information processing is transferred to the IU information processing device 15. |
