Description

[Detailed Description of the Invention] [Outline] The present invention is a button structure with a function display provided with a light-emitting source for illuminating and displaying the function display section in the same color as the display surface of the button. Since the illumination switching circuit that lights the light emitting source when the surroundings of the button is bright is provided, it is possible to improve the operability of the audio system by the button with the function display.

[Industrial applications]

 The present invention relates to a button with a function display.

The button with a function display is generally used for electric products in order to improve operability.

The present invention refers to a button structure with a function display of an audio system such as a radio cassette.

[Conventional technology]

FIG. 5 is a diagram showing a display / operation unit of a conventional audio system. First, the configuration will be described below. In addition, the same reference number or symbol is used to represent the same component throughout the drawings. In FIG. 5 (a),
The operation unit 10 has a plurality of buttons with function display 5 concentrated therein. Sixth
The figure is a view for explaining the button with a function display in FIG.
The button 5 with a function display in this figure is the operation unit 10 in FIG. 5 (a).
The button on the leftmost side of the figure is shown, and the function display section 3 is composed of "1" and "A". The function display section 3 is displayed in a color different from that of the button display surface 4 for easy identification. It is configured so that it can be operated with the same button. In the case of a vehicle, the radio ← → cassette deck is not always switched by the operation unit, and, for example, when a cassette pack is inserted, the function automatically switches to a cassette deck function.
The information display unit 11 displays information that can be operated by the operation unit 10.

The above description has been made for the case where the surroundings of the audio system are bright, but the case where the surroundings are dark will be described using FIG. 5 (b). In FIG. 5 (b), when the surroundings of the audio system are dark, a visible portion is indicated by a solid line and a visible portion is indicated by a dotted line. Since the function display portion 3 of the function display button 5 is thin so that light can pass therethrough, it is illuminated and displayed when illuminated from the back when the surroundings are dark. Light emitting sources 1-1 and 1-2 in FIG. 6 are lamps for illuminating “1” and “A” of the function display unit 3, respectively. Two lamps are provided so as to face the light shield plate 7 provided between "1" and "A" of the function display portion. Since the information display unit 11 is backlit, the information display unit 11 can be displayed in the same way as when it is bright even when the surroundings of the audio system are dark.

Next, the operation will be described. When the surroundings of the audio system are bright, the function display portion 3 of the function display button 5 illuminated by the ambient light is viewed and the function display button is operated.
By this operation, two functions can be switched with one button. Further, when the surroundings of the audio system are dark, the function display section 3 illuminated by the lamps 1-1 and 1-2 can be viewed to operate the button with function display. In this way, the buttons with function display have contributed to the improvement of the operability of the audio system because the buttons can be operated even in the dark surroundings.

[Problems to be solved by the device]

However, the conventional structure of the button with function display 5 has a problem that the display of the function display unit 3 of the button with function display 5 is different depending on whether the surroundings of the audio system are bright or dark. This problem will be described below. FIG. 7 is a diagram showing a display of the function display portion based on the light and shade around the audio system. In FIG. 7A when the surroundings of the audio system are bright, both “1” and “A” of the function display unit 3 are displayed. In order to distinguish the function display unit 3 from the display surface of the button, both colors are different, and even if only "A" is illuminated by the lamp 1-2 from the back side of the function display unit 3, This is because it cannot be distinguished from "1" which is not illuminated by the lamp 1-1. On the other hand, when the surroundings of the audio system are dark, in FIG. 7 (b), when "A" is illuminated by the lamp 1-1, only "A" is displayed,
Not displayed for "1". This is because the light shielding plate 7 shown in FIG. 6 is interposed between "1" and "A". In the figure, the part that can be seen is shown by a solid line and the part that cannot be seen is shown by a dotted line.

Therefore, when the environment around the audio system is dark,
The function display section 3 provides a quick response to the operation of the button with function display 5
Is displayed in. On the other hand, when the surroundings of the audio system are bright, it is difficult to judge even if the response to the operation of the button with function display 5 is displayed on the function display unit 3. Therefore, it is judged from the information display unit 11 in FIG. You must judge by listening. Therefore, the button structure with a function display has a problem that the operability of the audio system is inferior when the surroundings of the audio system are bright as compared to when the surroundings are dark.

Therefore, in view of the above problems, it is an object of the present invention to provide a button structure with a function display having the same display function with respect to the light and dark surroundings of an audio system.

[Means for solving the problem]

FIG. 1 is a diagram showing the principle configuration of the present invention. According to the present invention, in order to solve the above-mentioned problem, the second light source 2 illuminates the function display portion 3 so as to have the same color as the display surface of the button when the area around the button 5 with function display is bright. indicate. The illumination switching circuit 6 is the first when the surroundings of the button 5 with function display are dark.
The light source 1 is switched to, and when the function display is to be performed, it is turned on, and when the function display is not performed, it is turned off. When the area around the button with function display 5 is bright, it is switched to the second light emitting source 2, and when the function is requested, it is turned off, and when the function display is not requested, the function display portion 3 is illuminated and displayed.

[Action]

In FIG. 1, when the area around the button 5 with function display is bright, the illumination switching circuit 6 connects the second light source 2 to the power source V _B. When displaying the function of the function display unit 3, the second
The light emitting source 2 is turned off to make the difference in color between the function display section 3 and the display surface of the button stand out. When the function is not displayed, the second light emission source 2 is turned on so that the function display section 3 and the button display surface have the same color. When the area around the button with function display is dark, the illumination switching circuit 5 connects the first light emitting source 1 to the power supply V _B. Function display unit 3 by turning on / off the first light source 1.
Is illuminated.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a view showing an embodiment of the present invention,
FIG. 3 is a diagram showing an illumination switching circuit that lights up the light emitting source and expresses and displays the function display section. In FIG. 2, components different from those in FIG. 6 are the second light emitting sources 2-1 and 2-2, and in FIG. 3, components different from those in FIG. 6 are the illumination switching circuit 6. First, the configuration will be described. In FIG. 2, the color of the button display surface 4 is red, for example, and the function display portion 3 is milky white. Further, the second light emission sources 2-1 and 2
-2 is a red light emitting diode of the same color as the color of the display surface 4 of the button. The above is merely an example, and the color of the display surface 4 of the button may be green, and the second light source may be a green light emitting diode of the same color as the color of the display surface 4 of the button. Generally, button display surface 4
The color may be any color. In this case, the light emitting source is not limited to one and need not be limited to a light emitting diode, and is composed of three light emitting sources of three colors of red, green and blue,
It may be adjusted to match any color of the display surface 4 of the button.

Next, the operation will be described. FIG. 4 is a diagram showing the display of the function display section when the surroundings of the audio system are bright. In this figure, when the second light emission source 2-1 shown in FIG. 2 is lit by "1" of the function display unit 3, since "1" has the same color as the display surface 3 of the button, it is difficult to identify the function. “A” is displayed on the display unit 3. That is, the second light source 2-1 on the side where the function is not requested is turned on, and the second light source 2-2 on the side where the function is requested is turned off to display the function request. Therefore, the button structure with function display has the same display function not only when the surroundings of the audio system are dark but also when the surroundings are bright, and the operation is easy for the user.

When the color of the button display surface 4 and the color of the function display unit 3 are the same, the function display unit 3 is illuminated when the function is requested when the surroundings of the audio system are dark, and when the function is requested, the function display unit 3 is displayed when the function is requested. It is also possible to illuminate with a color different from the color of the display surface 4 of the button. However, in this case, since the function display unit 3 is not illuminated and displayed when the power is not turned on, there is little benefit of displaying no function and making the button the same color as the display surface 4 of the button.

FIG. 4 is a diagram showing an illumination switching circuit of a function display unit which illuminates a light emitting source to perform illumination display. In this figure, the switch
SW ₁ and SW ₂ blink the first light emitting sources 1-1 and 1-2 and the second light emitting sources 2-1 and 2-2, respectively. The switch SW ₃ is the first light source 1-1 and 1-2.
The power sources of the second light emitting sources 2-1 and 2-2 are switched. The switch switching control unit 8 has switches SW ₁ and SW ₂
And a control unit for switching SW ₃ . The inverter 9 inverts the function request signal level to switch the switch SW ₂ .

For example, since the blinking operation of the small lamp of the automobile coincides with the brightness of the surroundings of the audio system, the small lamp signal S ₂ is transmitted to the switch S via the switch switching control unit 8.
The first light emitting sources 1-1 and 1-2, the second light emitting sources 2-1 and 2-2, and the power supply V _B are connected by W ₃ . The function request signal S ₁ turns on the first light emission source, which should be displayed as a function, when the first light emission sources 1-1 and 1-2 are connected to the power source V _B via the switch changeover control unit 8. , The switch SW ₁ is switched so as to turn off the first light emitting source which does not need to display the function. When the second light emission sources 2-1 and 2-2 are connected to the power source V _B , the inverter 9 switches SW ₂ to be the reverse of the above.

〔The invention's effect〕

As described in detail above, according to the present invention, by providing a light emitting source that illuminates and displays the function display unit in the same color as the display surface of the button, the light emission source of the function display unit is turned on. Since the part disappears and the remaining function display section has the display function, it is possible to improve the operability of the audio system by the button with the function display.
