Next, in FIG, when the finger contact of user is to operation display part 32a in the operating area 32 of front panel 26, because electric current flows through between the electrode 34 of human body and operation substrate 27, thus the direct capacitance of electrode 34 changes.
Switch I C41 detects the change of this direct capacitance, thus detects that the finger of user has touched the operation display part 32a of operating area 32.Herein, along with the distance operated between the electrode 34 of substrate 27 and human body becomes greatly, the change of direct capacitance tails off.That is, along with the distance operated between the electrode 34 of substrate 27 and the dorsal part of front panel 26 becomes greatly, the change of direct capacitance tails off.Therefore, the electrode 34 of operation substrate 27 is narrower with the distance of the dorsal part of front panel 26, then can detect that user touches the situation of the operation display part 32a in operating area 32 more exactly.
Detection signal, when detecting by operation, is exported to display control unit 42 by switch I C41.
Display control unit 42 is based on this detection signal, make the static lighting of a part of corresponding LED (most) 40, and a remaining part of the LED (most) 40 of lighting all the time is also switched to static lighting by dynamic lighting (pulse lighting).In static lighting, owing to being energized always, therefore noise can not be produced, thus static capacitive touch switch can not cause misoperation.
When LED (most) 40 is luminous, its light is via diffusion barrier 30 from backside illuminated to mirror film 29, and corresponding Fumction display portion 46,66 is arrived illumination respectively.Now, each LED40 is individually surrounded by treatment cone portion 47, therefore can not drain to elsewhere from LED (most) 40 light sent, can only throw light on well to corresponding Fumction display portion 46,66.
User, as represented as display state in Fig. 4, sees front panel 26 from the front of operation panel unit 25, thereby, it is possible to see the part in illuminated Fumction display portion 46,66.
