Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a display device for anamorphosis images.

(Prior art) The anamorphosis image used in the present invention is
This is an interesting variant of the image devised by the German HA Liebitz in 1886. In normal conditions, this deformed image is distorted and the pattern cannot be recognized, but when viewed by reflecting it onto a reflective surface with a specific curve, a regular image can be obtained. As the specific curved surface, a surface such as a cone or a cylinder is generally used.

This anamorphosis image surface device has an eye-catching effect, so it is applied to various decorations including display devices such as POP.

(Problems to be Solved by the Invention) Generally, a surface device for anamorphosis images includes a reflecting mirror and an image carrier on which an anamorphosis image is formed. When a viewpoint is placed at a predetermined position with respect to the reflecting mirror, a reflected image of the anamorphic image on the image carrier is obtained as a regular image. However, conventional anamorphosis image display devices are configured with a one-to-one correspondence between a reflecting mirror and an image carrier, so they can only display one type of image at any time, making it difficult to display a wide variety of images. The problem was that it could not be done.

Therefore, an object of the present invention is to provide an anamorphosis image display device that can display a wide variety of images.

[Structure of the idea]

(Means for Solving Problems) The present invention provides an anamorphosis image display device that includes a concave mirror having a reflective surface inside, a front panel provided around the opening of the concave mirror, and a front panel provided at the bottom of the concave mirror. and an image carrier on which an anamorphosis image is formed. This makes it possible to display a wide variety of images.

(Function) The image carrier is supported by the rear support. Since this support is achieved by fitting, the image carrier is detachable and can be easily replaced. Therefore, it becomes possible to display a wide variety of images.

(Example) The present invention will be described below based on an illustrated example. FIG. 1 is a perspective view of an anamorphosis image display device according to an embodiment of the present invention, and FIG. 2 is a side sectional view of the device. A very large circular opening is provided in the center of the square front panel 1, and a concave mirror 2 is fixed to the back surface of the front panel 1. The concave mirror 2 has a truncated conical shape with a reflective surface on the inside, and the opening of the front panel 1 and the opening of the concave mirror 2 almost coincide with each other. Therefore, the front panel 1 is located on the outer periphery of the opening of the concave mirror 2. A substantially triangular holding plate 3 is supported inside the concave mirror 2. A cylindrical image carrier 4 is attached to this holding plate 3. This cylindrical image carrier 4 is divided into two by a plane including the central axis, and the upper carrier 4a is attached to the upper surface of the holding plate 3, and the lower carrier 4b is attached to the lower surface of the holding plate 3, respectively. An anamorphosis image 5 is formed on the surface of the image carrier 4, and when a viewpoint is placed in front of the front panel 1, the reflected image of the anamorphosis image 5 by the concave mirror 2 can be seen as a regular image 6. In other words, an anamorphic image 5 such that a regular image 6 can be obtained by reflection by the concave mirror 2 is provided on the image carrier 4 in advance.
It will be formed on top. The holding plate 3 is detachably supported by the front panel 1 and the rear support body 7.

FIG. 3 is a perspective view of the display device main body with the retaining plate 3 removed, and FIG. 4 is a perspective view of the retaining plate 3 itself with it removed. As shown in FIG. 3, the front panel 1 is provided with cutouts 8a and 8b, and the rear support 7 is also provided with cutouts 8c and 8d. On the other hand, as shown in FIG. 4, the holding plate 3 is provided with protrusions 9a to 9d.
When the holding plate 3 is attached to the display device main body (the state shown in FIG. 1), the protrusions 9a to 9d fit into the notches 8
It will fit into parts a to 8d. Due to such fitting, the image carrier 4 is firmly held via the holding plate 3. Further, since the holding plate 3 can be easily removed, it can be easily replaced with a holding plate 3 having an image carrier 4 on which a different image is formed, and various image displays can be made.

Note that the display device main body is attached with leg portions 10, and the display device main body itself is supported by the lower side of the front panel 1 and the leg portions 10.
For this reason as well, it is preferable that the front panel 1 is square. In particular, the square shape is excellent in terms of design.

Furthermore, the holding plate 3 can serve not only to firmly hold the image carrier 4 but also to hide the seam of the concave mirror 2. In order to reduce costs, the concave mirror 2 is often made by cutting out a flexible specular particle-deposited film into a fan shape and assembling it into a conical shape. Therefore, the seam 11 appears at the front as shown by the dashed line in FIG. By using the retaining plate 3, this seam 11 can be hidden.

Although the present invention has been described above based on one embodiment, the present invention is not limited to the above-mentioned shape, and various other shape changes are possible. Also,
The display device according to the present invention is not only applied to a simple POP display device, but can also be used to decorate all kinds of things such as speakers, calendars, clocks, and desk lamps.

For example, when used as a speaker, a piezoelectric speaker 12 is attached to the front end of the image carrier 4 as shown in FIG.
By adding the above, it is possible to realize a speaker using the concave mirror 2 as an acoustic reflector. Alternatively, the vibration coil 13 of the speaker may be directly connected to the concave mirror 2, and the concave mirror 2 itself may be vibrated to function as a cone of the speaker. When applied to a speaker in this way, a unique effect is produced in that the orientation of the speaker can be easily confirmed. In other words, if the design is made so that the viewpoint position where a regular image is observed matches the position where the optimal sound image is formed by the speaker, the listener will be able to see whether a regular image is being formed when looking at the speaker. By recognizing this, it is possible to judge whether or not the orientation of the speaker is optimal.

Further, as the means for supporting the image carrier, various means other than the above-mentioned embodiments may be used. For example, the 6th
In the embodiment shown in FIG. 7 as a perspective view and in FIG. . Since the diameter of the image carrier 4 is slightly larger than the diameter of the fitting member 14, the image carrier 4 can be freely inserted into and removed from the fitting member 14, and is held in a detachable manner. In this embodiment, a fluorescent lamp 15 is built inside the fitting member 14, and can be turned on and off by a controller 26. The fitting member 14 and the image carrier 4,
If it is made of a transparent or semi-transparent material, a display device with lighting effects can be realized.

On the other hand, in the embodiment shown in FIG. 8 as a perspective view and in FIG.
7 is fixed. Since the diameter of the image carrier 4 is slightly smaller than the diameter of the concave member 17, the image carrier 4 can be freely inserted into and removed from the fitting member 17, and is held in a detachable manner.

[Effect of idea]

As described above, according to the present invention, since the image carrier is detachably fitted and supported in the anamorphosis image display device, the image carrier can be easily replaced and a wide variety of image displays can be performed. It becomes like this.
