Abstract: A stop light for a vehicle mounted within the vehicle for flashing in synchronism with a brake comprises a light source arranged within the vehicle. A prism is so arranged as to feed a display light from the light source rearward of the vehicle. Further, the prism is so arranged that a driver can confirm a road surface at a rear location of the vehicle through the prism from a field of view of a back mirror. The prism may be formed into such a configuration that a surface thereof adjacent to the light source scatters a light from the light source. Moreover, the light source may be formed by a red light source.

Abstract: An indication display unit for vehicles of this invention is provided with a head-up display (HUD), an indication projector, a display device located at the ceiling of the vehicle, and a reflector forwardly located relative to a driver's seat.

Abstract: A prism is installed at a lower part of the windshield near the dashboard with a first surface of the prism directed toward a viewing point of a driver and a second surface held in contact with the inner side of the windshield. The first or second surface of the prism is made a reflecting surface. The third surface is formed with a dark paint layer. The apex of the prism where the first and second surfaces join is tilted toward the driver seat in such a manner that the second surface becomes a total reflection surface for light from the third surface with respect to the viewing point of a driver. The display image of an indicator installed in the dashboard below the prism is reflected either by the first or second reflecting surface of the prism toward the driver's viewing point. Light from the dark third surface of the prism is totally reflected by the second surface toward the driver to provide a dark background for the display, enhancing the display contrast.

The invention also includes a drive mechanism for shifting the position of the reflecting member in upward or downward to adjust the height thereof and a solenoid for pivotally shifting the reflecting mirror, when it is used, in response to the movement of the reflecting member for reflecting the information in the most effective angle toward the driver in accordance with the vehicle speed.

Abstract: A displaying apparatus for a vehicle to project a pattern to be displayed of an indicator on a half mirror disposed in front of a driver's seat such that a driver of the vehicle sees the pattern overlapping views outside a front windshield of the vehicle. The displaying apparatus comprises a projector for projecting the pattern. The projector includes the indicator, etc., and is received within a case which is provided to a ceiling in the interior of the vehicle to accommodate a room lamp. The half mirror is fitted to a fitting device installed on a dashboard of the vehicle such that an angle of the half mirror is freely set. The half mirror is set on the dashboard at an angle in a range between 100 and 120 deg. the angle being formed toward the front windshield from a horizontal line (0 deg) extending to the driver.

Abstract: In a head up display apparatus for an automotive vehicle including a projector unit disposed at the ceiling of the automotive vehicle to project display images and a half-mirror reflector unit for reflecting the projected display images to the driver, the height of the half-mirror reflector unit and the angular position of the projector unit are automatically adjusted according to vehicle speed, so that virtual display images can be appropriately seen by the driver ahead of the half mirror reflector unit along the driver's eye direction variable according to vehicle speed, by use of a relatively small half-mirror reflector unit.

Abstract: A display apparatus used in automobiles has an indicating device mounted in the steering column to display the car running condition information and a reflecting plate installed in the dashboard to form a virtual image of displayed information at a point on the far side of the reflection surface from the driver. To make it more easy for the driver to see the displayed information, the apparatus incorporates a magnifying cylindrical lens which is installed between the indicating device and the reflection plate in such a way that the display surface of the indicating device is within the focal length of the lens. The virtual image of the displayed information is thus magnified by the lens and formed farther away from the driver's viewing point, making the displayed information more easily recognizable. Another feature of the apparatus is that the cylindrical lens can also be moved to a desired position to magnify the displayed information to any desired size for the driver.

Abstract: A display apparatus for an automotive vehicle comprises a projector disposed at the ceiling of a vehicle passenger compartment to project display images and a reflecting member pivotally disposed in a dashboard of the vehicle to reflect the display images projected by the projector toward the driver. The reflecting member is a mirror or a hologram plate. The display images are stable without being subjected to the influence of external sunlight, while increasing the field of vision on the front windshield. Further, when the hologram plate is used, it is possible to obtain large display images in spite of a small-sized projector and to improve the visual recognizability of display images.

Abstract: In an on-vehicle head up display device employing a catopric system for a windshield glass of an automobile to project a display image onto an inner surface of the windshield glass, an optical system for letting a virtual image of the display image of a display means enter the windshield glass is adapted to make an angle formed by light beams of the virtual image entering the windshield glass less than a monocular resolving power. Further, an optical means for correcting parallax of the light beams of the virtual image is provided between the optical system and the windshield glass. Thus, a double image formation and binocular parallax may be eliminated.

Abstract: A display apparatus for a vehicle of the type wherein a display image of a display device located near a focus of an optical system is projected on a front glass of the vehicle so that a virtual image of the display image may be focused at a position forwardly of the front glass. In the display apparatus, when external light entering the optical system has an intensity higher than a predetermined level, a light intercepting means prevents the external light from being received by the display device, thereby preventing thermal destruction of the display device which may possibly be caused by heat given to the display device by intense external light such as the sunlight which is condensed by the optical system.
