A display input device includes a display unit, a touch panel unit for accepting an operation on a button displayed on the display unit. When the touch panel unit accepts a predetermined first operation, the display unit performs a list display of a predetermined or smaller number of reduced screens in order from the higher layer screen, each of which is smaller than a screen in the normal mode and is selected so as to move toward a lower layer one by one from a next lower layer screen of the screen on which the first operation is made.
