Abstract
The indication display unit according to the present invention is constructed such that an image indicated by an indicator disposed within the dashboard is projected towards and reflected on a prism provided at the lower portion of the windshield so that the driver can observe the image behind the prism as the virtual image thereof, and is characterized in that the prism can be shifted namely between the first and the second positions thereof, wherein when the prism is located in the first position, the indicated image projected from the indicator is reflected on the surface of the prism and directed to the driver'"'"'s visual point, whereas in the second position thereof, the prism has been completely shifted away from the driver'"'"'s visual field by position shifting elements, and the indicated image projected from the indicator is thereby reflected on the inner surface of the windshield and directed to the driver'"'"'s visual point. Further, the indication display unit constructed as above is also characterized in that the prism is shifted upward or downward along with the inner surface of the windshield, or that the prism is pivoted on a rotational shaft provided near the bottom surface thereof so as to be set either in the first position or in the second position thereof.
