Abstract
Official abstract text for this publication.
The head-up display device sequentially displays a virtual image ( 51 V) of a guide light from one end of a reflector ( 30 ) side, in the back inside of a virtual image ( 83 V) 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 ( 20 V) of display information in the back thereof. The amount of travel of the virtual images ( 51 V) 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 ( 20 V) of the display information. Therefore, even if the virtual image ( 20 V) of the display information falls outside the projection area, the virtual images ( 51 V) of the guide light remain in the projection area, and are displayed.
First claim
Opening claim text (preview).
The invention claimed is: 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 mov…
