Abstract

PURPOSE:To allow the visual admission of display contents in the remotest possible place by providing a display device which is disposed to have a nearly parallel display surface below the lower edge of the front windshield of a vehicle and in front of a driver's seat and an display which optically displays display information, half mirror which receive the display contents of the display surface and reflect the light forward to image the light as mirror images and a mirror which receives this mirror images and forms the images forward, thereby viewing the image of this mirror through the half mirror. CONSTITUTION:The half mirror 30 receives the display contents of an indicating meter 20 along an arrow A, reflects this light along an arrow B and admits the light into the half mirror 50 when the meter 20 displays a vehicle speed, etc., by a display panel 21 under illumination. The mirror 50, therefore, forms the mirror image of the mirror 30 in the position shown at the point Q. The display contents of the meter 20 are imaged by the mirrors 30, 50 in such a case and, therefore, the images are formed in the position forward of the imaging position of the mirror 30, i.e., the position forward by as much as the sum of the object point side distance of the mirror 50 and the 1st image point side distance. The imaging position of the display contents is thus further away than the single half mirror.

(Prior Art) Conventionally, in vehicle display devices, for example, Japanese Patent Laid-Open No. 63
As shown in Publication No. 232042, an indicator is disposed horizontally directly under a hood that extends horizontally from the lower edge of the vehicle windshield into the passenger compartment, and Directly below, a half mirror is arranged so as to be tilted sequentially downward from the front to the rear, so that the displayed content on the display surface of the indicator can be viewed by the passenger seated in the driver's seat through the half mirror. Is there a way to do that?

(Problem to be Solved by the Invention) In such a configuration, the passenger visually recognizes the display content of the indicator as a mirror image of the half mirror, but there is a difference between the imaging position of this mirror image and the half mirror. Since the distance between the mirror image and the - position is short, the visual distance for the occupant to the mirror image is also short. Therefore, there is a problem in that the travel distance of the line of sight from the far front to the lower half mirror when the passenger is driving the vehicle inevitably becomes long.

On the other hand, if you try to lengthen the distance between the mirror image formation position and the half mirror position, the distance between the indicator position and the half mirror position must also be lengthened. As a result, the space occupation rate under the hood of the display device increases, resulting in a decrease in space utilization.

(Operation and Effect) In the present invention configured as described above, both the half mirror and the mirror are employed, and the half mirror is
The display contents on the display surface of the display device are received and imaged forward as a reflecting mirror image, and the mirror receives the reflected mirror image and formed further forward, and the image of this mirror is Since the vehicle is visually recognized through the mirror, the distance between the position of the visually recognized image and the position of the occupant becomes much longer than in the case where only the half mirror is used. Therefore, when the line of sight of a passenger looking far ahead is directed towards the front mirror, the distance traveled by the same line of sight is shorter than before, and as a result, the vehicle can be driven smoothly. becomes. In such a case, the display content on the display surface is only visually recognized as an image formed on the mirror through the half mirror.
The space occupancy factor as a display device does not become large.

In such a case, the display contents of the indicator 20 are displayed on both half mirrors.
30 and 50, the image is formed at a position further forward than the image forming position of the half mirror 30, that is, only the sum of the distance on the object point side and the distance on the first image point side of the half mirror 50. The display contents of the indicator 20 are imaged at the front position. For this reason, the image formation position of the displayed content is further away from the driver's position than in the case of a single half mirror.

Therefore, when the driver turns his/her line of sight, which was directed far ahead, toward the half mirror 30 while driving the vehicle, the image formed on the No. 7 mirror 50 can be seen through the No. 7 mirror 30 along the direction of the arrow. However, as mentioned above, half mirror
Since the image formation position of 50 is further away from the driver's position, the distance the driver's line of sight must move from the far front to the half mirror 30 is shortened, and as a result, the driver's driving operation becomes easier. Become smoother.

Further, as described above, since the half mirror 50 is curved in the lateral direction with a predetermined radius of curvature, the /S-half mirror 50
A mirror image of the image is formed in a horizontally enlarged manner, as shown by the two-dot chain line E in FIG. For this reason, the display content of the indicator 20 is displayed larger than itself,
The visibility of this type of display device is improved. Furthermore, as described above, by employing both half mirrors 30 and 50, the display contents of the indicator 20 are optically imaged further forward, so that the space occupied by the display device directly under the hood 10 is reduced. rate can also be minimized.
