(a) First Display FIG. 5 is an explanatory diagram of a first display in the variable display structure of the first embodiment. FIG. 6 is an explanatory diagram illustrating a state in which the first display is performed in the variable display structure according to the first embodiment.
In Example 1, to display the first display 11 shown in FIG. 5, the first light source 6 is turned on and the second light source 7 is turned off.
The blue light emitted from the first light source 6 passes through the transparent sheet 4a and goes to each printing portion.

In the 1st printing part 4b, as shown to the relationship of the line 23 and the line 24 of FIG. 4, the light of the 1st light source 6 is allowed to pass through.
Next, as shown in the relationship between the line 21 and the line 24 in FIG. 4, the second printed portion 4 c does not transmit the blue light from the first light source 6. As a result, the portion is not displayed in the same manner as the background. In addition, in the part which the color filter 4 is not displayed, the solid shape painted in the metallic tone of the half mirror ring 3 can be seen.
Next, in the 3rd printing part 4d, as shown to the relationship of the line 24 and the line 25 of FIG. 4, the blue light of the 1st light source 6 is permeate | transmitted.
The background printing portion 4 e does not transmit both the light from the first light source 6 and the light from the second light source 7.
As a result, the first display 11 is displayed as shown in FIG.

More specifically, the display light transmitted through the first print portion 4b and the third print portion 4d is displayed through the half mirroring 3. Therefore, it becomes the metering 2 in which blue light is transmitted through the three-dimensional shape, and the design is very high.
Further, in the first display 11, when the display light transmitted through the first print portion 4 b is displayed through the half mirror ring 3, the concave portion 31 provided on the color filter 4 side of the half mirror ring 3 also passes. For this reason, the shape of the recessed portion 31 is displayed so as to emerge. This emerges together with the blue light of the first light source 6, and the design becomes very high. This shape is a shape portion that cannot be seen even when the second light source 7 is turned on when the first light source 6 is not turned on. For this reason, in the variable display structure of the first embodiment, by switching the light source, different shapes can be displayed together with different colors and designs, and display with very high design can be performed (see FIG. 6). ).

(b) Second Display FIG. 7 is an explanatory diagram of a second display in the variable display structure of the first embodiment. FIG. 8 is an explanatory diagram illustrating a state in which the second display is performed in the variable display structure according to the first embodiment.
In Example 1, to display the second display 12 shown in FIG. 7, the second light source 7 is turned on and the first light source 6 is turned off.
The red light emitted from the second light source 7 passes through the transparent sheet 4a and goes to each printing portion.

In the 1st printing part 4b, as shown to the relationship of the line 22 and the line 23 of FIG. 4, the red light of the 2nd light source 7 is not permeate | transmitted. Therefore, the part which is not displayed is constituted like the background. In addition, in the part which the color filter 4 is not displayed, the solid shape painted in the metallic tone of the half mirror ring 3 can be seen.
In the second printed portion 4c, the light from the second light source 7 is allowed to pass as shown by the relationship between the line 21 and the line 22 in FIG.
Next, in the 3rd printing part 4d, as shown to the relationship of the line 22 and the line 25 of FIG. 4, the light of the 1st light source 6 is permeate | transmitted.
The background printing portion 4 e does not transmit both the light from the first light source 6 and the light from the second light source 7.
Thereby, the second display 12 is displayed as shown in FIG.

More specifically, the display light transmitted through the second print portion 4c and the third print portion 4d is displayed through the half mirroring 3. Therefore, it becomes the metering 2 in which red light is transmitted through the three-dimensional shape, and the design is very high (see FIG. 8).
Further, the second printed portion 4c provided between the circumferential arrangement of the third printed portions 4d is displayed in red light with a radial shape close to the scale.

  This display portion is a display portion that is not visible even when the first light source 6 is turned on when the second light source 7 is not turned on. Therefore, in the variable display structure of the first embodiment, different colors and designs can be displayed by switching the light source, and a display with a very high design can be performed (see FIG. 7).

  In addition, in the lighting state of the second light source 7, the concave portion 31 of the half mirror ring 3 cannot be seen from the display side. In this portion, a metallic display painted on the surface by the reflectance of the half mirror ring 3 can be seen.

(c) When not lit When both the first light source 6 and the second light source 7 are not lit, the outer shape of the half mirror ring 3 is painted in order to have an appropriate reflectivity with respect to external light and illumination. It will be shown in a metallic color (see FIG. 1).
