PURPOSE:To prevent the generation of error data by writing data on a memory circuit, block by block, and reading blocks of written data in response to a write end signal. CONSTITUTION:When data is transmitted from a data terminal 1-1 to a data center 6, a CPU10 sends out a ready signal for writing to a CPU7 and a control circuit 13. Further, the control circuit 13 sends out a write signal to the memory circuit 8 and the ready signal is sent to a CPU2 through a transmission line 5 and the bus 3 of the data terminal 1-1 under the control of the CPU7. When the data is written in the memory 8 under the control of the CPU7, which then sends out a request signal for writing to the CPU10 and control circuit 13 to read said data out of the memory 8. Then, the read data is converted by a data converting circuit 9 to a data format suitable for data equipment. |
