Abstract

In the on-vehicle display unit 5, an indicated image on an indication surface 51a of the display 51 is reflected by a semi-transparent mirror 55 to be directed above a dashboard 1 through a window 59b formed in a cover plate 59a disposed on an upper surface 1a of the dashboard 1. Thereby, the image is projected on a windscreen 3. The semi-transparent mirror 55 is moved in a longitudinal direction of the vehicle, so that the vertical position of a projection point P1 or P3 of the image S1 or S3 on the windscreen 3 is changed such that the image is superimposed over the foreground at which a driver of the vehicle is looking. The cover plate 59a is supported by a cover support construction 59c so as to be movable in a longitudinal direction of the vehicle relative to the upper surface 1a of the dashboard 1.

Dependent claims

An on-vehicle display unit for projecting an image on a screen, the image displayed on a display in a dashboard of a vehicle, the screen disposed above the dashboard and extended diagonally in a vertical plane relative to a longitudinal direction of the vehicle, the screen being transparent so that the foreground is visible through the screen with the image projected on the screen being superimposed over the foreground, the on-vehicle display unit comprising:

a reflecting mirror disposed in the dashboard for reflecting light emitted from the image displayed on the display toward the screen;
wherein the reflecting mirror can be located at a plurality of different positions in a longitudinal direction of the vehicle;
and
a second reflecting element spaced from the display in a longitudinal direction of the vehicle, and the mirror is a semi-transparent mirror which can pass partially light emitted from the display toward the second reflecting element, the second reflecting element reflecting the light toward the semi-transparent mirror such that the light is reflected toward the screen by the semi-transparent mirror.
