  The present invention has been made paying attention to the above problems, and its object is to provide a variable display structure that can perform three types of display and can perform display even when there is no lighting. It is in.

  In order to achieve the above-described object, in the variable display structure of the present invention, the first display and the second light are emitted by switching the light of the first light source and the light of the second light source having different wavelengths on the light-transmitting sheet. A variable display structure for performing display, wherein a first printed portion that transmits only the wavelength of the first light source, a second printed portion that transmits only the wavelength of the second light source, and the wavelength of the first light source, A third printing portion that does not transmit the wavelength of the second light source, and a dimming printing portion that suppresses light of the first light source and the second light source at a portion that overlaps the overlapping portion of the first display and the second display; A fourth printed portion that transmits a wavelength of either or both of the first light source and the second light source and reflects external light to display, and includes a third display in addition to the first display and the second display. The display is performed.

  In the present invention, three types of display can be performed, and display can be performed even when there is no lighting.

  Hereinafter, an embodiment for realizing a distance image generating apparatus of the present invention will be described based on examples.

First, the structure will be described.
1 is a cross-sectional view showing a switch having a variable display structure according to a first embodiment. FIG. 2 is a front view of the color filter of the first embodiment. 3 is a cross-sectional view taken along the line AA in FIG. FIG. 4 is a front view of the color filter excluding the first smoke print portion, the second smoke print portion, and the white print portion. FIG. 5 is an explanatory diagram showing the relationship between the characteristics of the first printed portion and the second printed portion and the wavelengths of the first light source and the second light source. FIG. 6 is an explanatory diagram showing a state in which the first display, the second display, and the third display are displayed.
First, the switch 1 is provided with a rectangular frame-shaped guide housing 7 inside a rectangular frame-shaped switch finisher 2 (see FIG. 1).
The guide housing 7 is provided with a slidable rail portion in the direction from the opening surface of the rectangular frame-shaped switch finisher 2 to the opening surface, that is, the front and rear surfaces.
A plate-like substrate 6 that closes the opening is provided on the back side of the switch finisher 2 and the guide housing 7.

On the front side of the substrate 6, that is, on the inner side of the switch finisher 2, the first light source 3 having a peak of about 500 nm and the second light source 4 having a peak of about 600 nm are turned ON / OFF by being pushed. A tact switch 5 for performing the operation input is provided.
As the 1st light source 3 and the 2nd light source 4, although LED which develops a different color is preferable from a cost control and maintenance property, another thing may be used. Next, a slider 8 having double frame portions inside and outside is provided. The inner frame portion of the slider 8 is formed in a pyramid shape such that the inner side becomes narrower toward the first light source 3 and the second light source 4 side. Further, the frame-shaped portion inside the slider 8 extends rearward so as to cover the sides of the first light source 3 and the second light source 4.

Furthermore, an engaging portion 8 a that protrudes downward is provided on the downwardly inclined surface of the frame-shaped portion inside the slider 8. The position of the engaging portion 8a is set to a position where it engages with the tact switch 5 when moved downward.
A color filter 10 is provided on the front surface portion of the inner frame portion of the slider 8.
A smoke lens 11 having a generally low translucency is provided on the front surface of the color filter 10 in order to prevent the printed pattern from being seen by external light when the light is turned off.

Here, the slider 8 to which the smoke lens 11 and the color filter 10 are attached is engaged with the rail portion of the guide housing 7 so as to be slidable back and forth.
Thus, when the slider 8 is pushed toward the tact switch 5, the slider 8 slides and the engaging portion 8a having a shape protruding downward from the inclined surface pushes the tact switch 5.
Moreover, when it is set in a free state after being pushed, it is structured to return by the reaction force of the tact switch.

The color filter 10 has a first printed portion 10b, a second printed portion 10c, a dimming printed portion 10d, and a background printed portion 10e (first smoke printed portion 10f corresponding to the third printed portion) on the front surface of the transparent sheet 10a. The second smoke printing portion 10g (corresponding to the suppression portion in the first and second smoke printing portions 10f and 10g) and the white printing portion 10h (corresponding to the fourth printing portion) are provided.
Here, the first display 12 is “A” of the character shown in FIG. 6A, the second display 13 is “E” of the character shown in FIG. 6B, and the third display 14 is FIG. 6C. The letter “I” is shown.
The first print portion 10b is the portion of FIG. 4 that does not overlap the second display 13 “E” of “A” that is the first display 12, and is a red color print that allows red light to pass through. The characteristic of the transmission efficiency with respect to the wavelength of the first printed portion 10b is the characteristic indicated by the line 21 in FIG.

The second print portion 10c is the portion of FIG. 4 that does not overlap the first display 12 “A” of “E” that is the second display 13, and is a blue color print that allows blue light to pass through. The characteristic of the transmission efficiency with respect to the wavelength of the second printed portion 10c is the characteristic indicated by the line 23 in FIG.
The light control printing unit 10d is a portion of FIG. 4 where “A” as the first display 12 and “E” as the second display 13 overlap, and is a print that allows red light and blue light to pass therethrough. In Example 1, the color is purple.

Next, after providing the first print portion 10b, the second print portion 10c, and the like, the first smoke print portion 10f, the second smoke print portion 10g, and the white print portion 10h are printed.
First, the second smoke print portion 10g is provided in the portion “I” which is the third display. The white print portion 10h is printed so as to overlap the second smoke print portion 10g. The first smoke print portion 10f is printed on the portion other than the second smoke print portion 10g and the white print portion 10h. The first smoke print portion 10f is printed so as to have the same ink thickness as the second smoke print portion 10g and the white print portion 10h. Further, the smoke density is adjusted so that the light transmittance of the first smoke printed portion 10f is equal to the light transmittance of the second smoke printed portion 10g and the white printed portion 10h. It shall be.

That is, one surface constituted by the first smoke print portion 10f, the second smoke print portion 10g, and the white print portion 10h is configured to have substantially uniform light transmission.
In the first embodiment, since the first smoke print portion 10f and the second smoke print portion 10g are provided, the smoke density of the smoke lens 11 may be reduced accordingly.

Next, the operation will be described.
[Display effect]
(a) First Display In Example 1, to display the first display 12, the first light source 3 is turned on and the second light source 4 is turned off.
The light emitted from the first light source 3 reflects the light diverging to the side of the first light source 3 forward by the inner frame of the slider 8.
Light enters the color filter 10 from the front surface portion through the internal space of the inner frame of the slider 8.

Then, the light passes through the sheet 10a, and the first print portion 10b allows the light from the first light source to pass as shown in FIG. 5 (the relationship indicated by the lines 21 and 22), so the first print portion 10b is bright. indicate.
Furthermore, since the light control printing unit 10d transmits both the light from the first light source 3 and the second light source 4, in this case, the light from the first light source 3 is transmitted. The light control printing unit 10d displays brightly with colors close to the first printing portion 10b.

On the other hand, since the second printed portion 10c has a characteristic indicated by a line 23 with respect to the characteristic (line 22) of the first light source 3 in FIG. 5, the light of the first light source 3 cannot pass therethrough.
Further, the background printing portion 10e does not allow the light from the first light source 3 or the light from the second light source 4 to pass through.
Furthermore, since the first smoke printed portion 10f, the second smoke printed portion 10g, and the white printed portion 10h are uniform light-transmitting smoke surfaces, the luminance is slightly increased regardless of the wavelength characteristics of the display light. Allow light to pass through. Therefore, the light from the first light source 3 that has passed through the first printing portion 10b and the light from the first light source 3 that has passed through the light control printing unit 10d are slightly darkened by the smoke action and pass display light. For this reason, the difference in color between the first printing portion 10b and the light control printing portion 10d becomes more difficult to recognize, and it is difficult to distinguish between the distances viewed by the actual user. In this way, the first display 12, that is, “A” shown in FIG. 6A is displayed.

(b) Second Display In Example 1, in order to display the second display 13, the second light source 4 is turned on and the first light source 3 is turned off.
Then, since the relationship between the second printed portion 10c and the second light source 4 is the relationship between the line 23 and the line 24 in FIG. 5, the second printed portion 10c is displayed brightly.
Furthermore, since the light control printing unit 10f allows the light of both the first light source 3 and the second light source 4 to pass therethrough, in this case, the light of the second light source 4 is allowed to pass. The light control printing unit 10d displays the color and brightness close to those of the second printing portion 10c.

On the other hand, since the relationship between the first printed portion 10b and the second light source 4 is the relationship between the line 21 and the line 24 in FIG. 5, the light from the second light source 4 cannot pass therethrough.
Further, the background printing portion 10e does not allow the light of the first light source 3 and the second light source 4 to pass through.
Furthermore, since the first smoke printed portion 10f, the second smoke printed portion 10g, and the white printed portion 10h are uniform light-transmitting smoke surfaces, the luminance is slightly increased regardless of the wavelength characteristics of the display light. Allow light to pass through. Therefore, the light of the second light source 4 that has passed through the second printing portion 10c and the light of the second light source 4 that has passed through the light control printing unit 10d are slightly darkened by this smoke action and pass the display light. For this reason, the difference in color between the second printing portion 10c and the light control printing portion 10d cannot be further recognized, and cannot be distinguished from the distance viewed by the actual user. In this way, the second display 13, that is, “E” shown in FIG. 6B is displayed.

(c) Third Display In Example 1, in order to display the third display 14, both the first light source 3 and the second light source 4 are turned off.
Then, the first smoke printing portion 10f, the second smoke printing portion 10g, and the smoke lens 11 reduce the translucency, thereby making it impossible to see the printing pattern inside the smoke printing.
When the first smoke printed portion 10f is viewed from the outside through the smoke lens 11, the color of the smoke looks dark.
On the other hand, the white print portion 10h on which the letter “I” is formed is arranged on the display surface side, and the second smoke print portion 10g is arranged on the light source side, so that the white print portion 10h reflects external light. Thus, when the white printed portion 10h is viewed from the outside through the smoke lens 11, it appears white.
As a result, the character “I” which is the third display 14 is displayed.

In other words, when the light from the first light source 3 and the second light source 4 passes through the white print portion 10h and the second smoke print portion 10g, the light transmittance is equivalent to that of the first smoke print portion 10f. The reflected light of the white printed portion 10h is only reflected to the light source side and does not affect the display.
On the other hand, when the first light source 3 and the second light source 4 are turned off, the person sees the reflected light from the white print portion 10h of the external light, which is a new display.

[Switch action]
In the first embodiment, when the operator pushes the smoke lens 11, the integrated slider 8 slides and a part of the slider 8 pushes the tact switch 5.
As the switch 1, a display circuit (not shown) provided on the substrate 6 determines in which display state an input is made to the tact switch 5, and is used as two operation inputs. Thereby, operation input in different modes can be performed with one switch.

[Improvement of display quality]
The frame-like portion of the slider 8 collects light toward the side of the light source and directs it forward. Therefore, overall brighter display can be achieved and display quality is improved.

Next, the effect will be described.
In the variable display structure of the present embodiment, the following effects can be obtained.
