Abstract: An apparatus is provided for magnifying a display surface of an indicator and forming an image of the display surface at a forward place distant from a driver and other passengers in a motor vehicle. The apparatus comprises an indicator (11), a concave mirror (15), and a half mirror (13). The concave mirror (15) and the half mirror (13) serve to enlarge an image (20) of a display surface (12) of the indicator (11) and form the enlarged image at a forward place distant from a driver and passengers in a vehicle. The apparatus is provided with a cylindrical lens portion (14) by which the magnifying power of the image (20) in right and left directions is set at 1.2 to 2.5 while the magnifying power in up and down directions is set at 1.2 to 1.6.

Abstract: The present invention provides an apparatus for a head up display for the use of a motor vehicle, which can make a presentation of an image information in a remote place and which can remove a height-wise positional displacement of a double image and distortion of the double image caused by the curved shape of a vehicle front glass to the extent possible. In the apparatus for a head up display for the use of a motor vehicle according to the present invention, a projector (3) has a middle mirror (6) for reflecting an image information (9) such as characters or marks toward a reflective face. The middle mirror (6) includes a portion (18) of the parabolic reflective face which is located away from a main axis of a parabolic mirror.
