An anomaly detector detects anomaly of a first device. A second device reset part, in case that anomaly has been detected by the anomaly detector, resets a second device. A first device reset part, in case that anomaly has been detected by the anomaly detector, resets a first device. Further, a collating part collates data generated by the first device with data generated by the second device, and judges anomaly when these data are in disagreement with each other. A reset part, in case that the anomaly has been judged by the collating part, resets the second device.
