Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a display meter such as a speedometer or a sound meter.

(Prior Art) An analog car speedometer will be explained as an example. As is well known, the display section of this type of speedometer consists of a speed display scale, a panel on which speed display numbers corresponding to the speed display scale are printed or pasted, a pointer indicating the position of the scale, and a guard to prevent dust from entering. It is constructed with a cover glass as the main component. Needless to say, the speedometer is one of the important instruments indispensable for driving a car safely. Therefore, it is necessary for the driver to be able to read the information accurately at all times while driving. In addition, in order to give a sense of spaciousness in a narrow space like a car, instruments such as the speedometer are displayed on a flat surface using perspective, and even small irregularities are made to appear larger. .

(Problems to be Solved by the Invention) However, since the above-mentioned device utilizes an optical illusion, so to speak, it is not preferable for stereoscopic display. Furthermore, in addition to the display function, the above-mentioned instruments also play an important decorative role, and a display with more depth is one way to satisfy this need, but with conventional configurations, the actual depth of the display itself is greatly reduced. We will have no choice but to create a new structure. However, in a limited area where it is necessary to rationally arrange various instruments and devices, this method occupies extra space, which has an adverse effect on the arrangement of other instruments. Therefore, the present inventor previously proposed displaying the display scale etc. spatially, but although this proposal solved the above-mentioned disadvantage, the information provided to the driver and other observers by the display scale etc. Therefore, for example, in the case of the above-mentioned automobile, when it was applied to something other than a speedometer, the number of instruments applied was the same as in the past, and there was a problem that they were crowded into a narrow space.

Therefore, an object of the present invention is to provide a display meter that allows checking a plurality of displays without moving the viewpoint.

[Structure of the Invention] (Means for Solving the Problems) A hologram is provided with a hologram forming a plurality of images having different floating amounts during reproduction illumination, and a reproduction illumination source illuminating the plurality of images of the hologram. It is structured as follows.

(Operation) A plurality of images are displayed simultaneously and separated from each other within a predetermined space.

(Example) Hereinafter, the present invention will be described based on drawings showing examples.

FIG. 1 shows one embodiment of the present invention, taking an automobile's display meter as an example. That is, this display meter illuminates two different types of display parts, for example, a hologram 3 forming a speed display image 1 and a rotation speed display image 2 indicating the engine speed, and a speed display image 1 and a rotation speed display image 2. Reproduction illumination source 4 and speed display image 1
It also includes a speed pointer 5 and a rotation speed pointer 6 pointing to each display position of the rotation speed display image 2. The speed display image 1 includes a speed display scale 7, a speed display number 8,
The rotational speed display image 2 includes a rotational speed display scale 9 and a rotational speed display number 10, both of which are photosensitively fixed. The speed display image 1 and the rotation speed display image 2 are formed so that, when illuminated by the reproducing illumination source 4, the amount of spatial elevation for three-dimensional display is different to the extent that it can be visually determined, as shown in the figure. has been done. Also,
The speed pointer 5 and the rotation speed pointer 6 are fixed to a double drive shaft 11 that is coaxial like a long hand and a short hand.
It is designed to be rotated according to changes in speed and rotational speed, and is positioned so as to rotate on the same plane as the plane corresponding to each of the above-mentioned floating amounts.

In the above configuration, for example, when the regenerative illumination source 4 is turned on at the same time as the car starts, the speed display image 1 and the rotational speed display image 2 float on different planes as shown in FIG. displayed as an image. These images are different from ordinary objects;
Even if there is an image in the foreground, you can see the entire image in the background even from the same viewpoint. In addition, when displaying, it can be confirmed more clearly by using different colors for each combination.

In the above embodiment, two types of different display images have been described, but even if there are three or more different display images, for example, as shown in FIG. It may be displayed like this. Further, in the above embodiment, a display meter such as a speedometer of an automobile was described, but the present invention is not limited thereto, and can be applied to a display meter of various instruments such as a display meter of an audio device or a thermometer.

[Effects of the Invention] Since a plurality of pieces of display information are simultaneously displayed in a predetermined spatial area, space saving is achieved without requiring many displays. Furthermore, since the information can be checked at the same location, there is no need to move the viewpoint to multiple locations, which contributes to safe driving, for example, when driving a car.
