Abstract

PURPOSE:To perform registering functions even when a master ECR is in transmission operation by providing the master ECR with the functions of judging the presence of a key input even during the data transmission and performin processing based upon the key input. CONSTITUTION:In a master ECR, a keyboard 23 and a display device 24 are connected to a CPU21 through a keyboard/display device control circuit 22, and an ROM25 and an RAM26 are also connected to the CPU; and a printer 28 is connected to the CPU through a printer control circuit 27, and a transmission interface circuit 30a for a central controller connected to a transmission inerface circuit 30a for the master ECR of the central controller and a transmission interface circuit 30b for a subordinate ECR connected to the subordinate ECR are connected to the CPU through a transmission control circuit 29.
