Abstract: An HUD includes a housing that accommodates a light modulation unit that spatially modulates light emitted by a light source; a projection optical system that is accommodated in the housing and projects the light that has been spatially modulated onto a windshield of a vehicle 1 through an opening portion of the housing; a cover that closes the opening portion; a protection member that is movable and is for protecting the cover; a driving unit that drives the protection member; and an object detecting unit that detects an object approaching a front surface of the cover. The driving unit moves the protection member to a position above the cover and causes the protection member to cover the cover when the object detecting unit detects an object, and the driving unit leaves the protection member retracted from the position above the cover to expose the cover when the object detecting unit does not detect an object.

Abstract: An HUD includes a housing that accommodates a light modulation unit that spatially modulates light emitted by a light source; a projection optical system that is accommodated in the housing and projects the light that has been spatially modulated onto a windshield 2 through an opening portion K of the housing; a cover that closes the opening portion K; a separation member that is movable and is for separating a front surface of the cover into a plurality of regions; a driving unit; and an object detecting unit that detects an object approaching the front surface of the cover. The driving unit moves the separation member to a position on the cover to separate the cover into a plurality of regions when the object detecting unit detects an object, and leaves the separation member retracted from the position on the cover when an object is not detected.
