[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same members or the same functions as those in FIG. 5 are denoted by the same reference numerals.
[0012]
FIG. 1 shows a vehicle display device A as an embodiment of the present invention. This vehicle display device A is provided with a pointer 4 that is driven by a movement 3 at the rear of the case 1, and a half mirror 6, which is a light-transmitting reflecting member, faces upward in front of the pointer 4. Arranged at an angle. A transparent dial plate 7 with a design for displaying a virtual image is attached to the upper part of the case 1 with respect to the half mirror 6 at an angle of about 45 degrees. As shown in FIG. 2, the transparent dial 7 has a scale 9 and numerals 10 printed on the surface of a light-transmitting resin disc 8 such as an acrylic resin material.
[0013]
A dome-shaped cover member 11 is attached above the transparent dial 7. The cover member 11 is formed by printing or painting a light reflecting film 11b that reflects light on the outer surface of a dome 11a made of a light transmissive resin material such as acrylic resin. Thereby, the light can be reflected without passing through the cover member 11.
[0014]
Light sources 14 are disposed at both ends between the transparent dial 7 and the cover member 11, and the surface of the transparent dial 7 is illuminated by the light sources 14. As a result, as shown in FIG. 3, the scale 9 and the numeral 10 of the transparent dial 7 are incident on the half mirror 6 as a direct image and reflected by the half mirror 6 and reflected by the cover member 11. The reflected image is incident on the half mirror 6 and reflected there as shown by the solid line 16. At this time, the direct image of the dotted line 15 and the reflected image of the solid line 16 are reflected so as to be shifted, so that the observer 9 sees the scale 9 and the number 10 shifted from each other, resulting in a three-dimensional result. Become visible.
[0015]
FIG. 4 shows a display device B for a vehicle as another embodiment of the present invention. In this vehicle display device B, the cover member 11 is obtained by applying a suede-like coating 17 to the inner surface of a dome 11a (material is arbitrary).
[0016]
By applying the suede-like coating 17 in this way, the surface of the coating 17 serving as the background of the scale 9 and the numeral 10 becomes uneven. For this reason, when the light source 14 is turned on, the surface of the scale 9 and the numeral 10 of the transparent dial 7 is illuminated with the light, reflected on the surface of the paint 17 by reflection, and further reflected on the surface of the paint 17 to be half This is where the observer 18 visually recognizes through the mirror 6. At this time, to the observer 18, the scale 9 and the number 10 are shifted from each other due to the uneven state of the surface of the paint 17 and appear double, resulting in a three-dimensional appearance.
[0017]
【The invention's effect】
As described above in detail, according to the first aspect of the present invention, the transparent dial for displaying the virtual image is provided on the upper part of the half mirror, and the cover member covering the transparent dial is provided on the outer surface of the transparent dome. Since it has a structure with a light reflecting film, a scale, a direct image of numbers and a reflected image from the cover member are incident on the half mirror, and the difference between the direct image and the reflected image causes the viewer to see the scale and numbers. Is doubled, and the scale and numbers look three-dimensional, and a display design rich in change can be obtained.
[0018]
Further, according to the invention described in claim 2, since the cover member is configured to have a light-reflective suede-like coating on the inner surface of the dome, the coating surface serving as the background of the scales and numbers is in an uneven state. Therefore, the scale and numbers appear to be doubled due to the unevenness of the painted surface, and thus the scale and numbers can be seen three-dimensionally. It is done.
