ABSTRACT:
An after-change supply prevention unit prevents a cross coil from being supplied with a driving pulse signal with a duty ratio corresponding to a deflection angle calculated based on a period of a running pulse in a duration in which a period range judging unit judges that the period of the running pulse generated with the running of a vehicle is not in a predetermined range after the input state of the running pulse is shifted from the input state at the stoppage of the vehicle to the input state in running of the vehicle. While the supply of the driving pulse signal is prevented, a driving pulse signal with a duty ratio corresponding to a deflection angle calculated based on the period of the running pulse at the stoppage of the vehicle is supplied to the cross coil.
