A control apparatus for input screens includes a display unit, a switch portion and a control unit including a microcomputer. If one of a menu switch of the switch portion and a plurality of dummy switches included in a screen displayed by the display unit is operated, the microcomputer causes the display unit to display a new screen including a plurality of dummy switches. The microcomputer estimates a time period required for the operator to watch a screen to operate the dummy switch, depending on the displayed screen (the number of dummy switches). If the sum of estimated time periods exceeds a reference time period, the microcomputer nullifies operation of the dummy switch to prevent the screen from being switched. After the lapse of a predetermined time period, the microcomputer cancels the nullification of the operation of the dummy switch.
