Head-up display device
First Claim
1. A head-up display device, including:
- a box-shaped case having an opening;
a display source that is disposed within the case;
a reflector that is displaceably disposed within the case so as to reflect the display light of the display information displayed on the display source toward a projection area disposed in a window shield of a vehicle through an opening of the case; and
a reflector displacement unit that displaces the reflector so as to move a projection position of the display light on the projection area in a vertical direction of the vehicle;
wherein the head-up display device is equipped with a guide light unit having at least one of a plurality of luminous bodies aligned along an optical path of the display light, and a rod-like luminous body arranged along the optical path of the display light, on an inner surface of the case between the display source and the reflector.

Abstract
The head-up display device sequentially displays a virtual image (51V) of a guide light from one end of a reflector (30) side, in the back inside of a virtual image (83V) of an opening bezel formed into a square frame displayed along an outer edge of a projection area (71) of a window shield, and further displays a virtual image (20V) of display information in the back thereof. The amount of travel of the virtual images (51V) of the guide light when the reflector provided in the head-up display device rotates is smaller than the amount of travel of the virtual image (20V) of the display information. Therefore, even if the virtual image (20V) of the display information falls outside the projection area, the virtual images (51V) of the guide light remain in the projection area, and are displayed.
