1. Field of the Invention
The present invention relates to indication display units for vehicles, and more particularly to an indication display unit for vehicles which displays information concerning driving operation at a position corresponding to an instrument panel on a dash board.
2. Description of the Prior Art
Conventionally, various information concerning driving operation such as the vehicle speed, engine revolutions, residual fuel quantity, time and other various warnings have been indicated by meters, a clock or alarm lamps provided on an instrument panel. Recently, however, in order to ensure sufficient space in a dash board, there has been proposed that a semi-transparent reflecting mirror is located at a position of an instrument panel, and an indicating means for indicating revolution frequency of engine, vehicle speed, residual fuel quantity, etc. to be essentially indicated is mounted on a lower surface of a meter hood, while various warning lamps which are not so essential are located behind the reflecting mirror. With this arrangement, the displayed image from the indicator is reflected on the reflecting mirror, and the images from the warning lamps are transmissively observed through the reflecting mirror (Japanese Utility Model Laid-open Publication No. 60-152544).
In this conventional device, both the transmissive image from the warning lamps and the displayed image from the indicating means are visually observed by the driver. Simultaneously, a sufficient space may be ensured in the dash board by not locating the indicating means behind the instrument panel, namely, in the dash board.
However, as the meter hood is yet present, and the reflecting mirror is located at a position deeply inside the dash board, a sufficient space to be defined in the dash board is limited. Further, the meter hood is intended not only for the location of the meter indicator but also for prevention of reflection of the image from the warning lamps located behind the reflecting mirror on a windshield. Accordingly, even if the meter indicator is located at any position other than the meter hood, the meter hood is yet necessary to prevent the reflection of the image from the warning lamps on the windshield.
