Abstract

PURPOSE:To make it possible to easily adjust a visual focusing even when a user alternately looks at a distant view and the display of a measuring instrument, by forming the image of an indicator revolving behind the surface of a hologram and the image of graduation at the almost same depth position. CONSTITUTION:When a light source 7 is allowed to light to illuminate a hologram 1 for a meter board and a hologam 2 for an indicator, the images of graduations 13, an indicator 14, a figure 15 and a unit mark are formed at the almost same depth position spaced apart by about 1m from the rear surfaces of the holograms. Further, by revolving the hologram 2 for the indicator 14 by a measuring instrument main body 4 through an indicator shaft 5 and a transparent plate 6, the image of the indicator 14 revolves at said depth position to display a speed. Because the hologram 2 for the indicator made of a transparent disc and the transparent plate 6 are arranged so as to cover the central part of the front surface of the hologram 1 for the meter board, the images of the graduations 13, figure 15 and unit mark of the hologram 1 for the meter board can be three-dimensionally looked through the hologram 2 for the indicator and the transparent plate 6 even when a user looked at the meter board 1 from an oblique forward direction.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention is for thinning out a DL device suitable as an automatic checker.

(Prior art) Conventionally, in order to display scale numbers, etc. three-dimensionally, the thickness of a transparent plate is changed and printing is performed, or two transparent plates are used to print scales, numbers, etc. (For example, Japanese Patent Laid-Open No. 59-203919).

[Problem that the invention seeks to solve]

However, in the conventional products mentioned above, the three-dimensional effect was given in the physical position mainly for the purpose of design, and the driver, who is the user, was able to interact with a distant mouse from outside. There was no improvement in the ease of adjusting the viewpoint when alternately looking at the instrument display.

Therefore, the present invention allows the user to easily adjust the viewpoint even when viewing the distant view and the instrument display alternately.

[Means for Solving the Problems] Therefore, the present invention includes a case, an instrument body housed in the case, and an instrument body that is rotated by the instrument body and illuminated by a light source to illuminate the rear part of the hologram surface. A hologram for Jn Kushi, in which information about the pointer is recorded so as to create an image of finger metal 1, is placed on the front of the main body of the d instrument, and when illuminated with a light source, the image of the pointer is almost the same as the image of the pointer at the rear of the hologram surface. To provide a meter equipped with a hologram for a scale plate in which scale information is recorded so as to create a scale image at the same depth position.

[Effect]

According to this, if the light d9 is -(11<+bright'4, Hol,
At the rear of the plane, the rotated 1Fi9+ image and the 11mm image are created at approximately the same depth position.

〔Example〕

Embodiments of the present invention shown in the drawings will be explained below.

In FIGS. 1 to 3, reference numeral 10 denotes a case in which a meter body 4 for speed display is housed. Reference numeral 9 denotes a facing plate IIIJ transparent protective plate placed on the open end side of the case I, which covers the open end II of the case IO from the facing plates 90), . l is a hologram for the scale plate.

It is fixed to +iii of the meter body 4 by the soto 3.

Reference numeral 5 denotes a pointer shaft which is rotated by the instrument body 4 and is provided so as to pass through approximately the center of the scale plate hologram 1. 2 is a transparent disc-shaped water 1" 1 grano, which is fixed to the -C finger 11 shaft 5 through a disc-shaped transparent plate (j), and a scale plate vologram l, the center part of 1 is ”(1) Plate plate
, 1 Grano, is placed in front of l. Also transparent plastic
/-16 The central part of the front face is printed or decorated in black to prevent the pointer shaft 5 and its surroundings from being seen from the front. 7 is fixed to the front lower part of the dial 7 board 9 through a printed wiring board 8 in order to make the pointers 1:1 graph 1, 2 and the scale plate hologram 1 diagonally lower and in front. It is a light source. Then, when the scale plate point 11 is illuminated by the light source 7, there will be a mark 13, a speed numeral I5, a speed unit symbol 16, etc. at a position about 1 m behind the scale surface. Information such as a scale 13, numbers 15, and level symbols 16 are recorded so as to create an image of the display.The pointer hologram 2 also has information such as 1 (@) from the hologram surface when illuminated by the light source 7. Information on the pointer 14 is recorded so as to create an image of the pointer 14 in the rear part at almost the same depth position as the image of the scale 13. Here, the pointer hologram 2 is illuminated by the light source 7 diagonally from below and in front. Therefore, the rotation trajectory of the image of the pointer 14 due to the rotation of the pointer porogram 2 is not completely centered on one point, but the rotation trajectory of the pointer 14 is 11 along the rotation trajectory of the pointer 14.
Scale 1; information on scale 13 so that an image of (
It is preferable to record on one hologram J.1.

In the configuration below-F, when light 11iii7 is not lit, 4
As shown in FIG. 2, no display appears on the scale plate hologram 1 and the pointer hologram 2.

Therefore, when the light source 7 is used as a side lamp to illuminate the hologram 1 for the scale plate and the hologram 2 for the pointer, as shown in FIGS. 1
5. Unit symbol 1 [i cl) An image is created at approximately the same depth ji h7 ia' about 1 m behind the song. Also, in the al vessel main body 4. 1. For IH Kumikawa ■Gram 2 with 1-7 through 11 axis 5 and transparent plate 6
By rotating, the speed is displayed by rotating at the depth position of the wound of phase opening I4.

Also, covering the center part of the front of the scale plate hologram l,
Since the finger hook bologram 2 and the transparent plate 6 made of transparent discs are arranged, even when the user views the scale plate l from diagonally forward, the scale can be seen through the pointer hologram 2 and the transparent plate 6. Scale 1 of board hologram 1
3. You can see the image of the number 15.141st symbol 16 in three dimensions.

FIG. 4 shows another embodiment of the present invention, in which the scale plate hologram 1 is constructed of a transparent plate, and a disc-shaped phase opening hole 1 is provided on the back side of the scale plate hologram l. 2 and a disc-shaped plate 6 are arranged, and the pointer hologram 2 is fixed to the finger hook shaft 5 via this plate 6, so that the entire surface of the pointer hologram 2 is covered by the scale plate holograms J and l. (there is no need to cover the central part and its surroundings), and the command 1 hologram 2 is illuminated by light from the light source 7 that passes through the dial hologram 1.

In addition, in each of the embodiments described above, both holograms l and 1
．． Although the light source 7 was placed on the front side of hologram 1.2, both holograms 1.
By forming 2 from a material with good optical transparency,
Depending on the situation, it is also possible to arrange the light sources 7 on all sides of both holograms 1.2.

- In the embodiments described above, the present invention is applied to the motor vehicle speed d1
However, it goes without saying that the present invention can also be applied to other four automobile equipment such as engine dip resistance, water temperature resistance, and oil pressure gauge.

〔Effect of the invention〕

As mentioned above, in the present invention, the image of the rotating pointer and the image of l=1 are created at approximately the same depth position at the rear of the hologram surface, so that the user can easily see the distant view and the instrument display. It is possible to adjust the viewpoint clearly even when looking at the scale alternately, since the image of the finger ≦ 1 and the image of the scale are created at approximately the same depth position,
This has an excellent effect in that even if the angle at which the user views the meter display changes, the indication on the pointer can be read accurately.
