PURPOSE:To avoid trouble of code management and to allow free classification, by providing further a start memory for each EOR and designating a PLU code to a PLU memory based on the start code preset to the start memory. CONSTITUTION:Based on a control switch 9 and a keyboard 2 and also a program of an ROM14, a CPU11 drives a data input control circuit 17 and writes the data from the keyboard 2 in an RAM12. Of course, the data inputted from the keyboard 2 is temporarily stored in each buffer memory in an RAM13. A data transmission control circuit 22 controls transmission/reception under the control of the CPU11 to operate a transmission circuit 23, and the data transfer with other ECRs(MR), (SR1)-(SRn) is made via a transmission cable 24. |
