Abstract
An information display device includes a display with a display screen, a multifunction switch, an IR sensor detecting whether or not an operator's hand is in a range around the multifunction switch, and a menu display controller. The menu display controller causes, based on a sensor signal from the IR sensor, a main menu to be displayed on the display screen when an operator's hand comes in the range. When the operator's hand is taken off the multifunction switch, the menu non-display window is displayed on the display screen after a time-out time has passed.
