3. Modification Example 1

Next, a modification of the second embodiment will be described. 5 is a view conceptually showing a configuration of the light emitting button device 30 according to the first modification.

Variation 1 differs from Embodiment 2 in that the light emitting button device 20 has one display portion 22 per touch switch 21 and the control portion 23 has one driven portion 24 However, in the first modification, the light-emitting button device 30 may be configured such that one touch switch 31 has two or more display portions and two or more portions to be driven, or one to- It differs in that it does different actions.

The touch switch 31 is the same as the touch switch 31 of the second embodiment.

The first display section 32 and the second display section 33 are basically the same as those of the display section 22 of the second embodiment and are different from the second embodiment in that the display section 22 of the second embodiment is transparent The second display unit 33 may be a transparent or opaque organic light emitting display. However, the first display unit 32 may use only a transparent organic light emitting display The display state of the second display unit 33 can not be confirmed from the outside since the first display unit 32 covers the display light of the second display unit 33. [

The control unit 34 selectively turns on or off the first driven unit 35 and the second driven unit 36 in accordance with the operation of the touch switch 31 and controls the first display unit 32 and the second display unit 33 ) Selectively or simultaneously to the display or non-display state.

The first driven portion 35 and the second driven portion 36 are different electrical devices. For example, in the case where the light emitting button device 30 of the present modification is used in an automobile, for example, the first driven portion 35 The second driven portion 36 may be a tail lamp or the first driven portion 35 is a first-stage drive control portion for rotating the heater at a low speed while the driven portion is a heater and the second driven portion 36 may be a two-stage driving control unit for rotating the heater at a relatively high speed.

Next, the operation of the light emitting button device 30 of Modification 1 will be described with reference to the case where the first driven portion 35 is the tail lamp of the automobile and the second driven portion 36 is the headlamp. At this time, it is assumed that the first display portion 32 displays an image when the tail lamp is on and the second display portion 33 displays the image when the head lamp is on.

First, the control unit 34 monitors whether or not there is an electric signal transmitted from the touch switch 31. If there is an electric signal transmitted from the touch switch 31 by the user's operation, It is determined whether any one of the driving unit 35 or the second driven unit 36 is in the currently lit state and if both of the first driven unit 35 and the second driven unit 36 are in the unlit state, 35 to control the taillight to be lit, and the first display unit 32 to be in the display state, thereby indicating that the taillight is lit.

If the taillight is in the on state and the headlamp is in the unlit state, the control unit 34 controls the second driven unit 36 to turn on the headlamps to turn on the taillights and the headlamps together, The state in which the taillight and the headlight are simultaneously lit, that is, the first display section 32 and the second display section 33 are both turned on.

If both the taillight and the headlamp are lit, the control unit 34 controls the second driven unit 36 to turn off the headlamps so that only the tail lamp is turned on and the second display unit 33 is set to the non-display state.

If the taillight is in the lighting state and the headlight is in the unlit state and two electric signals are transmitted from the touch switch 31 within a predetermined time (for example, one second), the control unit 34 controls the first driven unit 35 to turn off the taillight and at the same time bring the first display unit 32 to the non-display state.

In the above description, the first driven portion 35 and the second driven portion 36 are the tail lamps and the headlamps of the vehicle, respectively, and the controller 34 controls the taillamps, the headlamps, and the first and second display portions 32 and 33 However, this is merely an example, and various types of control can be performed according to the program stored in the memory of the control unit 34. [

In this modification, the number of the display portions is two and the number of the driven portions is two. However, the number of the display portions and the driven portions may be two or more.

4. Variation Example 2

Next, Modification 2 will be described. 6 is a view conceptually showing the configuration of the light emitting button device 40 of the second modification.

Variation 2 differs from Embodiment 2 in that in Embodiment 2, the control section 23 controls the driven section 24 and the display section 22 by an electric signal generated by a user operating the touch switch 21 The light emitting button device 40 of the second modification includes a push switch 42 such as a tact switch that operates in conjunction with the operation of the display section 41 when the user presses the display section 41, The control unit 43 is different in that it controls the driven unit 44 and the display unit 41 by an electric signal from the push switch 42. The functions and operations of the other components are the same as those of the second embodiment.

5. Modification 3

Next, Modification 3 will be described. 7 is a view conceptually showing a configuration of the light emitting button device 50 according to the third modification.

Variation 3 differs from Variation 2 in that there are two or more display portions 51 and 52 and driven portions 55 and 56 in Modification Example 3, 2 are combined.

Therefore, when the user presses the third display portion 51, the fourth display portion 52 and the push switch 53 are pushed together, and the control portion 53 pushes the push switch 53, And selectively controls the third to-be-driven portion 55, the fourth driven portion 56, the third display portion 51 and the fourth display portion 52 according to an electric signal from the control portion 50. In addition, same.

6. Embodiment 3

Next, a third preferred embodiment of the present invention will be described. 8A is a view showing the appearance of the light emitting button device 60 according to the third embodiment and Fig. 8B is a view showing the configuration of the heater switch 61a portion of the light emitting button device 60 according to the third embodiment Fig.

The light emitting button device 60 according to the third embodiment has a plurality of touch switches and a plurality of display sections, and the operation speed or intensity of the driven section operated by the selected touch switch among the plurality of touch switches is controlled by one variable means It is an appropriate example to apply to the control form.

As shown in Fig. 8, the light emitting button device 60 of this embodiment is a structure that is arranged in an integrated manner on a display panel of a control target electric device such as a display panel of an automobile or a washing machine. In Fig. 8, And the seat heater switch 61e are collectively arranged as shown in Fig. 8, and the two touch switches of the upper heater Below the respective touch switches, a heater display portion 62a, a vertical blowing display portion 62b, an upward blowing display portion 62c, a temperature display portion 62d, and a seat heater display portion 62e And a rotary knob 66 for varying the operating speed or the operation intensity of the portion to be driven selected by these five touch switches.

Each touch switch has a heater switch 61a and a heater display portion 62a as shown in Fig. 8 (b) conceptually showing the configuration of the heater switch 61a portion of the light emitting button device 60 of the third embodiment. And the heater 64a and the rotary knob 66 as the driven parts and the heater switch 61a is shown in Fig. 8 (b). However, even in the case of other touch switches, 8 (b).

Here, the control unit 63 and the rotary knob 66 are components shared by the entire light-emitting button device 60. [

Next, the operation of the third embodiment will be described.

First, when the user presses a desired touch switch among the plurality of touch switches, for example, the heater switch 61a, the control unit 63 recognizes the current driving state of the heater 64a. When the heater 64a is stopped The heater 64a is controlled to be in a driving state and the heater 64a is stopped when the heater 64a is in operation while controlling the heater display portion 62a to display a state corresponding to the state of the heater 64a .

The control unit 63 recognizing the touch of the heater switch 61a determines that the heater 64a is being driven when the heater display unit 62a is in the display state and stops the operation of the heater 64a, When the heater display portion 62a is in the non-display state, the controller 60 determines that the current heater 64a is currently in the stopped state and switches the operation state to the display state of the heater display portion 62a And the heater 64a and the heater display portion 62a may be controlled by other algorithms.

The important point here is that the control unit 63 judges which of the plurality of touch switches is the signal from the touch switch and switches the driven unit corresponding to the touch switch to the driving or stopping state and corresponds to the operating state of the driven unit To the display state or the non-display state.

When the heater switch 61a is pressed, for example, among the plurality of touch switches, the controller 63 connects the rotary knob 66 to a controller (not shown) for controlling the rotational speed of the heater 64a, When the rotary knob 66 is rotated clockwise or counterclockwise, the rotational speed of the heater 64a is changed to a high speed or a low speed.

The rotary knob 66 may control other functions instead of controlling the rotational speed of the driven portion like the heater 64a, for example.

What is important here is that the rotation knob 66 is to be combined with each of the plurality of touch switches to further perform additional functions other than those corresponding to the touch switch.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

It is to be noted that each of the above embodiments and modifications may be wholly or partly combined.
