Abstract
The electronic apparatus includes a direct-current voltage generation part that generates a direct-current voltage from a commercial power supply; a switching part that switches between an on-state in which the direct-current voltage from the direct-current voltage generation part is output, and an off-state in which the output of the direct-current voltage is shut down, a control part that controls operation of the direct-current voltage generation part; and a power supply maintaining part connected to the direct-current voltage generation part, the power supply maintaining part instructing the switching part to be in the on-state or the off-state, and consequently, enables provision of a soft-switch electronic apparatus that after recovery of a power failure, automatically returns to a state before occurrence of the power failure.
