PURPOSE:To improve the loss of actuation time by specifying and sending a data transmission command, which can be executed, to a central controller when processing based upon a data transmission command from the central controller can not be executed. CONSTITUTION:In a subordinate ECT, a keyboard 53 and a display device 54 are connected to a CPU51 through a control circuit 52, and an ROM55 and an RAM56 are also connected to the CPU51; and a printer 58 is connected to the CPU via a control circuit 57, and a transmission interface circuit 60 for a master ECR connected to a transmission interface circuit 30b for the subordinate ECR of the master ECR is connected to the CPU through a transmission control circuit 59. In the ROM55, a transmission program for setting in the RAM56 transmitted data based upon commands from the master ECR and for transmitting the data stored there to the master ECR is written previously in addition to a processing program regarding respective services selected with a mode selector switch. |
