The device (10) has a projection module (11) for generating an image to project the image in a normal sight direction (15) of a user i.e. driver, along an optical path (12). A reflection element (13) is displaced between different display positions corresponding to different viewing positions of the user. A covering unit covers the reflection element when the reflection element is positioned in its rest position. The reflection element is driven in rotation around a physical rotational axis by a linear motor element and by an endless screw transmission element i.e. roller.
