PURPOSE:To unnecessitate exclusive master and slave electronic each registers (ECR), to reduce manufacture cost and to simplify forward management by switching a function as the master equipment or the slave equipment corresponding to a switching instruction. CONSTITUTION:A slide switch type master/slave changeover switch M/S is provided on the keyboard of an input part 11 at the ECR. This master/slave changeover switch M/S functions the ECR as a master or a slave corresponding to the switching position, a mode designation signal outputted corresponding to the switching position is inputted to a CPU 12, and the CPU 12 switches the function to the slave side ECR or the master side ECR. According to a microprogram stored in advance, the CPU 12 selectively executes the processing of the slave side ECR or the master side ECR based on the output from the master/slave changeover switch M/S. |
