Abstract

PURPOSE:To eliminate the problem of the installation space for a display unit and further to prevent a lens and a mirror in a projector from blurring by introducing dry air into an air blow duct, thereby the visibility of the unit may be prevented from lowering, by using a part of the air blow duct as the interior of the projector in a vehicle display unit. CONSTITUTION:A projector 4 has a transparent upper lid 4a in the upper section thereof, and incorporates therein a fluorescent tube 8 for displaying drive information, in addition to a lens 6 and a mirror 7. Ventilating ports 9a, 9b and air guides 9c, 9d are formed in a lens holder 9 on both sides of the lens 6 supported in the lens holder 9. With this arrangement in which a part of an air-conditioning air blow duct is used as the interior of the projector 4, the problem of the installation space for the projector 4 which is caused when the projector 4 is arranged inward of an instrument panel, does not occur. Further, since dry air may be introduced into the projector 4, blur on the outer surface of the lens may be completely cleaned.

るものである。Recently, in order for drivers to view this information without having to take their eyes off the road ahead, the driving information is projected onto a reflector installed on the inside of the windshield or displayed on a display device attached to the front of the windshield. Alternatively, it is being considered to form a virtual image in front of the windshield and display it superimposed on the foreground. This type of display device is called a head-up display device, and was originally developed for aircraft pilots.It uses lenses and mirrors to project driving information images displayed on an information display such as a fluorescent display tube or liquid crystal display. An image is formed by projecting the image through a device.

In order to achieve this purpose, the projector is connected to the middle of an air conditioning duct, and the inside of the projector is used as a part of the air passage.

（ホ実絶倒 以下本発明を図面に基づいて説明する。(I'm absolutely devastated) The present invention will be explained below based on the drawings.

第１図は本発明による車両用表示装置の一実施例の要部
概略斜視図を示しており、１はフロントガラス、２は空
調用送風ダクト、３は温風。FIG. 1 shows a schematic perspective view of essential parts of an embodiment of a vehicle display device according to the present invention, in which 1 is a windshield, 2 is an air conditioning duct, and 3 is hot air.
