When the potential difference signal becomes lower than the constant voltage, the comparator 63 outputs an "H" level output. When this is connected for a predetermined time (for example, 1 minute) or longer, the cooler start command signal is output from the high-stage timer circuit 64. Is emitted. This start command signal is input to the cooler control circuit 65, and the cooler moves to blow cool air to the driver and restore the high awakening state again.
