<p>PURPOSE:To facilitate the operability of button functions after setting the various kinds of the button functions within a fixed display area without reducing the display area for other than the button functions on a display screen. CONSTITUTION:The initial setting of the function buttons displayed on the display screen is performed in a step 100, the function buttons are selected in the step 200 and the change or execution of the button functions is judged in the step 300. The button function is changed to a next candidate in the step 400, the button function of the next candidate is displayed in the step 500 and the selected button function is executed in the step 700. Thus, handleability is improved since the button function used at all times is preferentially displayed and the other display screen area is not occupied and display screen information is not reduced since the function buttons are displayed only within a fixed function button area. Further, since the plural display function buttons are simultaneously selected and different functions are called, a lot of the button functions are set.</p> |
