Claims

[Claims for Utility Model Registration] (1) A display device placed at the dash board position of a vehicle with the display surface facing upward, and a prism angle above the display device with the apex of the prism angle facing downward and a reflective surface. a first prism arranged with one interface inclined toward the driver's seat; and a second prism arranged with the vertex of the prism angle facing upward and the first interface facing the second interface of the first prism. The display image of the display device is displayed on the first prism of the first prism.
The display image is reflected to the driver's seat side at the interface so that it can be seen within the field of view of the windshield, and
Regarding the light rays that enter the second prism from a direction substantially opposite to the indicator,
A head-up display device for a vehicle, characterized in that total reflection is caused at the first interface of the second prism. (2) A display device placed at the dash board position of a vehicle with the display surface facing upward, a plurality of prisms connected together with the apex of each prism angle facing downward, and a reflective surface formed by the connection. A first prism continuum is arranged above the display device with the first interface inclined toward the driver's seat side, and a plurality of prisms are connected with the apex of the prism angle facing upward, and the first interface is arranged above the display. a second continuous prism body disposed facing a second interface of the first continuous prism body, the display image of the display being reflected toward the driver's seat side at the first interface of the first continuous prism body; The display image is made visible within the field of view of the windshield, and the second prism series is configured to allow light rays incident on the second prism series from a direction substantially opposite to the indicator from the second prism series. A head-up display device for a vehicle, characterized in that the light is totally reflected at the first interface of the body. (3) A head-up display device for a vehicle, wherein the second prism according to claim 1 and the second prism series according to claim 2 are attached to a windshield of a vehicle.
