Abstract

In a multi-function switch, while a first level screen inclusive of images representative of a plurality of object appliances viewed at operation buttons is displayed on a display means, an image of a selected appliance is selected by pressing any one of the operation buttons. Next, a second level screen inclusive of a plurality of functions of the selected appliance is displayed on the display means. In this configuration, not only the number of the operation buttons but also the space required for displaying the selected appliance can be reduced. When an air conditioner mode is selected from the first level screen, by pressing one by one a operation button for air drafting, in accordance with the number of times of pressing, the symbol representative of drafting mode is changed in a sequence of six patterns of “no drafting”, “only head”, “both head and leg”, “only leg” “only leg with defogger” and “head and leg with defogger”. In this configuration, the multi-function of a operation button for stepwise setting an operation of the air conditioner can be also realized.

Claims

1. A multi-function switch device comprising:

a plurality of operating operation buttons (α

1-α

n) each for selecting object appliances and their operation;

a display means (15j) on which images indicative of functions of the operation buttons are displayed, the images being viewed at the corresponding operating operation buttons;

means (31A) for executing the display of a first level screen representative of a plurality of object appliances to be selected on the display means (15j);

means (B) for detecting whether or not any of the operation buttons has been pressed while the first level screen is displayed;

means (31B) for specifying an image of the appliance to be displayed on the display means (15j) in response to detection of a pressed operation button; and

means (31C) for executing the display of a second level screen representative of a plurality of functions of a specific appliance, wherein the images of the second level screen replace entirely the images of the first level screen,

wherein while the first level screen or the second level screen is displayed on the display means (15j), in a first operation button region except at least one of the plurality of operation buttons (α

1-α

n), the corresponding functions are viewed, whereas in a second operation button region constituting the at least one operation button, additive information relative to functions of the operation buttons viewed in the first operation button region is viewed.

2. A multi-function switch comprising:

a plurality of operating operation buttons (δ

1-δ

n) each for selecting one of operations of a specific object appliance;

a section (D) through which an operation of the specific appliance is selected using any of the operation buttons (δ

1-δ

n);

a section (E) through which a change of setting of the operation of the object appliance is instructed;

display means (15j, 15k) for displaying the operations of the specific appliance which are viewed at the corresponding operation buttons (δ

1-δ

n); and

display changing means (33A) for changing the display of the display means (15j, 15k) so that in response to an instruction of changing the setting of the operation, selective operations relative to at least the setting are viewed at the operation buttons, wherein the changed display of the operations of the specific appliance replace entirely the previous display of the operations of the specific appliance,

wherein an image of the first color is viewed against a background of the second color at a first operation button region composed of some of the plurality of operation buttons, whereas the image of the second color is viewed against the background of the first color at a second operation button region composed of the remaining operation buttons, and the first and the second operation button region are switched by a selecting means (F).

3. A multi-function switch device comprising:

operation button means (α

) for stepwise setting one of operations of an object appliance;

display means (15j) for displaying the set operation which is viewed at the operation button means;

means (A′

) for detecting that any one of operation button means has been pressed;

means (31A′

) for deciding the step of the operation set by the operation button means on the basis of a detection result of the detecting means (A′

); and

means (31B′

) for creating image information of a character to be viewed at the operation button means on the basis of a decision result of the deciding means (31A′

) so that the character representative of the operation of the object appliance viewed at the operation button means is changed in accordance with the step on the display means,

wherein the image information to be viewed at the operation button means replaces entirely the previous information viewed at the operation button means, and

wherein the operation button means includes an increment operation button for incrementing the step of the operation of the object appliance and a decrement operation button for decrementing the step thereof; and

the step deciding means decides that the step of the operation is now a minimum value when the operation detecting means detects the operation of the increment operation button in a state where the step of the operation is decided to be a maximum value, and decides that the step of the operation is now a maximum value when the operation detecting means detects the operation of the decrement operation button in a state where the step of the operation is decided to be a minimum value.

4. The multi-function switch device according to claim 3, wherein the operation button means further includes a default operation button for setting the step of operation at a default value between the minimum value and the maximum value, and the step deciding means decides that the step of the operation is now a default value when the operation detecting means detects the operation of the default operation button.
