First Claim
1. A head-up displaying device for a vehicle comprising:
- a case secured to a vehicle interior and having an opening;
a projecting means disposed in said case for projecting a display image;
a reflecting member, disposed in said case and facing said projection unit, for directing said display image through said opening toward a prescribed spot outside said case;
a combiner secured to said case to receive said display image at said spot for focussing said display image into a virtual image; and
a hinge member connecting said case and said combiner so that said combiner may be inclined;
said hinge member comprises a holder to hold said combiner, said holder having shafts on both sides thereof and U-shaped clips having open ends fitted into said case for securing said shafts therein with such a frictional force as to hold said combiner at a given inclination angle.

Abstract
All components and parts of a head-up displaying device are formed in a unit and secured to a dashboard or a rear panel of a vehicle. The displaying device has a case composed of a base member, a bottom plate and a cover. The base member is secured to the dashboard or the rear panel and forms a turntable with the bottom plate. An image projection unit, a control unit and a reflecting member are housed in the case, and a foldable flat combiner is pivotally secured to the cover of the case. A shade member is formed on the cover to prevent the image projection unit from coming into the driver'"'"'s line of sight. The combiner is held by a holder which forms a hinge using clips secured to the case and shafts formed on the sides of the holder so that the inclination angle of the combiner may be adjusted. The combiner encloses a reflection hologram and an aspherical concave lens formed on the reflection hologram with glass panes or transparent plates made of resinous material which are covered with anti-reflection coatings.
