Abstract
When a change in an output voltage of a main power supply is a decrease, and a degree of the decrease is larger than a reference value, a power supply control portion decreases a boosted voltage of a voltage-boosting circuit according to the degree of the decrease. When the change in the output voltage of the main power supply is an increase, and a degree of the increase is larger than the reference value, the power supply control portion increases the boosted voltage of the voltage-boosting circuit according to the degree of the increase.
