Abstract
In a button for an electronic device, a red numeral pattern 21, a green kana pattern 31 and a black English character pattern 41 are printed on a key top 11 as plural kinds of patterns. By selectively causing a red LED 51 and a green LED 52 that function as a light source of a backlight to emit a light, red, green and orange lighting colors of the backlight are obtained. According to the color of the pattern used according to a mode, the lighting color of the backlight is switched.

1. An electronic device, comprising:
-
a button having at least a first pattern and a second pattern; and
a lighting device that emits at least a first lighting color and a second lighting color to illuminate the button, wherein the first pattern has a first pattern color and the second pattern has a second pattern color;
wherein said button comprises at least said first pattern having said first pattern color, said second pattern having said second pattern color, and a third pattern having a third pattern color. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)
wherein said combination color is a combination of said first lighting color and said second lighting color, wherein said lighting device emits said combination color by simultaneously emitting both said first lighting color and said second lighting color, and wherein said third pattern is easy for a user to see when said lighting device emits said combination color. -
3. An electronic device as claimed in claim 2, wherein said third pattern is difficult for a user to see when said lighting device emits only one of said first lighting color and said second lighting color.
-
4. An electronic device as claimed in claim 2, wherein said third pattern color is a complement of said combination color.
-
5. An electronic device as claimed in claim 2, wherein said first pattern color is substantially different than said second lighting color,
wherein said second pattern color is substantially different than said first lighting color, wherein said second pattern is easy for said user to see when said lighting device emits said first lighting color, and wherein said first pattern is easy for said user to see when said lighting device emits said second lighting color. -
6. An electronic device as claimed in claim 2, wherein said first pattern color is substantially the same as said first lighting color,
wherein said second pattern color is substantially the same as said second lighting color, wherein said first pattern is difficult for said user to see when said lighting device emits said first lighting color, and wherein said second pattern is difficult for said user to see when said lighting device emits said second lighting color. -
7. An electronic device as claimed in claim 2, wherein said first pattern is more easily seen than said second pattern and said third pattern when said lighting device emits said second lighting color and does not emit said first lighting color,
wherein said second pattern is more easily seen than said first pattern and said third pattern when said lighting device emits said first lighting color and does not emit said second lighting color, and wherein said third pattern is more easily seen than said first pattern and said second pattern when said lighting device emits said combination color. -
8. An electronic device as claimed in claim 7, wherein said first pattern color is a complement of said second lighting color, and
wherein said second pattern color is a complement of said first lighting color, and wherein said third pattern color is a complement of said combination color.

9. An electronic device, comprising;
-
a button comprising at least a first pattern having a first pattern color, a second pattern having a second pattern color, and a third pattern having a third pattern color; and
a lighting device that emits at least a first lighting color, a second lighting color, and a combination color to illuminate the button, wherein the lighting device emits the combination color as a combination of said first lighting color and said second lighting color by simultaneously emitting both said first lighting color and said second lighting color, wherein said first pattern color is substantially different than said second lighting color, wherein said second pattern color is substantially different than said first lighting color, and wherein said third pattern color is substantially different than said combination lighting color. - View Dependent Claims (10, 11, 12)
wherein said first pattern is easy for said user to see when said lighting device emits said second lighting color. -
12. An electronic device as claimed in claim 10, wherein said second pattern is easy for said user to see when said lighting device emits said first lighting color, and
wherein said first pattern is easy for said user to see when said lighting device emits said second lighting color.
