[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device mounted on an automobile, and more particularly to an enlarged display device for enlarging and displaying a display surface of an analog instrument using a Fresnel lens.

[0002]

2. Description of the Related Art As this kind of conventional enlarged display device,
There is a structure as shown in FIGS. That is, this display device has the instrument housing 3 fitted and held in the opening 2 formed in the instrument panel 1,
In the instrument housing 1, an analog speed type 4 for displaying the vehicle speed and an analog tachometer 5 for displaying the rotation of the engine are arranged.
That is, an enlarged Fresnel lens plate 6 is attached to the opening 2 of the instrument housing 1, and the speed meter 4 and the tachometer 5 are seen through the Fresnel lens plate 6 to be formed in a small size. Each instrument is displayed enlarged. Reference numeral 7 denotes a front cover disposed in front of the Fresnel lens plate 6, a mechanical body of the instruments 4 and 5, and 9 a steering wheel provided on a steering shaft 10.

[0003]

However, the center of the vortex of the Fresnel lens 6 used in the enlarged display device having such a structure is located at the center of the instrument dial, in other words, at the center of the opening of the instrument housing 3. Since the Fresnel lens plate 6 is used after being cut so as to be located at the center, the vortex shape at the center of the Fresnel lens plate 6 provided in the instrument housing 1 is particularly conspicuous, and However, there is a problem that a strange feeling occurs when viewing the display and the display quality is deteriorated.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem. A Fresnel lens plate is arranged in front of a display in which a plurality of analog instrument main bodies are arranged side by side. In a display device for enlarging and displaying each instrument main body, a Fresnel lens plate formed by forming a donut-shaped lens for enlarging and displaying a character display portion provided on a peripheral portion of the display surface excluding the center of the display surface of each instrument main body. The present invention is to provide an enlarged display device in which the display scale and the display characters of each analog instrument main body are enlarged and displayed, and the displayability and visibility of each instrument main body can be enhanced.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIG. 3. The present invention has a feature in the structure of a Fresnel lens plate disposed in front of a display, and has other features. Since the structure is the same as that of the conventional example, the configuration of the Fresnel lens of this example will be described.

That is, the rectangular Fresnel lens plate 11 used in the magnifying display device of this embodiment has vortex centers corresponding to the analog instrument main bodies 4 and 5, respectively. Magnifying lens part 1 with center
Numerals 2 and 13 are for enlarging the display portions of the display portions 4a and 5a, such as annular display scales and display characters, provided on the display surfaces of the instrument main bodies 4 and 5, respectively. The central portion is in an enlarged display form of, for example, a donut shape that does not expand.

[0007] By using the Fresnel lens plate 11 in which the magnifying lens portions 12 and 13 are formed in a donut shape corresponding to the display surfaces of the instrument main bodies 4 and 5, the characters and scales of the instrument are particularly improved. Since the tips of the hands 4b and 5b approaching the character graduations 4a and 5a are enlarged and displayed, the indicator required by the analog type instrument is particularly enlarged and displayed, thereby improving the visibility of each instrument. There is a feature that.

[0008]

As described above, according to the present invention, the Fresnel lens plate 11 is disposed in front of a display in which a plurality of analog instrument main bodies 4 and 5 are juxtaposed, and the surface of the display is enlarged. In the display device, the Fresnel lens plate 11
Are display units 4a, 5a such as characters, scales, etc. provided on the periphery of each of the analog instrument main bodies 4, 5 except for the center of the display surface.
Donut shaped lens parts 12 and 13
And the center of those lens parts is inside each instrument body 4 and 5 .
Since the magnifying display device is formed so as to correspond to the heart, the magnifying lens portions 12 and 13 are formed in a donut shape corresponding to the display surfaces of the instrument main bodies 4 and 5. By using the Fresnel lens plate 11, each
Characters and scales of the analog instrument main unit and its character scale 4
a, guidance 4b approaching 5a, tip of 5b are enlarged, thereby instructing unit that required in the analog type meter body is particularly enlarged, and each analog meter
It is not a display part such as characters and scales on the main unit
Since the non-display part in the center is a non-enlarged display,
The enlarged display of the display section becomes remarkable, and the effect of improving the visibility of each instrument is obtained.
