A destination input screen is displayed, and it is determined whether a start button is depressed. If the start button is depressed, it is determined whether a destination is already input on the destination input screen. If the destination is input on the destination input screen before the start button is depressed, the input destination is set. A scan and transmission processing is executed. If the destination is not input on the destination input screen when the start button is depressed, a registered destination is set to the destination.
