Claims

[Scope of utility model registration request]

Two systems of signal input terminals to which digital signal inputs are respectively led from the first system and the second system, two systems of power input terminals to which power is selectively applied, and two systems of power input terminals. The above 2 depends on which side the power is applied to.
a digital circuit that selects one of the different digital signal inputs of the signal input terminals of the system; and two systems that derive the digital signal input selected by the digital circuit and output it correspondingly to the first system and the second system. A redundant ink face circuit comprising: a signal output terminal;
