PROBLEM TO BE SOLVED: To provide an on-vehicle equipment for ETC (vehicle for settling a charge by a charge reception system) for activating a transmission part and a protocol processing part only at the needed time and effectively reducing power consumption. SOLUTION: A reception part 13a in an activated state at all times inputs data interruption signals Da to a control microcomputer 14a at the time of data reception from on-road equipment 2 and the control microcomputer is activated from a low power consumption mode corresponding to the interruption signals 16a-18a and Da, outputs the activation signals ERA and EPA of the transmission part 13B and the protocol processing part 15A corresponding to only the data interruption signals and is restored to the low power consumption mode together with the transmission part and the protocol processing part at the point of time of ending the corresponding processing of the respective interruption signals. |
