Abstract
Abstract A facsimile apparatus has an AC power source and a standby power source which are selectively changed. The number of times of changing the power sources is minimized to limit deterioration of the AC power source. When the frequency of use of the facsimile apparatus is high, the AC power source is maintained in the on state.
