Material, PC (polycarbonate, polycarbonate) synthetic resin such as material or its alloy material form.As front panel 11
A part operation portion 12 wall ratio operation portion 12 other than front panel 11 wall thickness it is thicker, be 2.5~4.0mm degree.
Front panel 11 is synthetic resin, so being also possible to deform, distorting.In this case, operation substrate 15 in order to prevent
It is angularly contacted with 12 shape of operation portion, in other words to contacting operation portion 12 and electrode 14 in parallel, preferably becomes wall thickness
It is thick.
In the back side (product back side) of operation portion 12, it is configured with the electrode 14 of detection electrostatic capacitance change.14 quilt of electrode
It is printed onto operation substrate 15, is fixed in the face side of control unit 30 via retainer 16.Plate 11 and electrode 14 in front
Between, partition 17 is configured in a manner of not generating gap.Flexible conducting rubber material has also can be used in partition 17
Or conductive other materials.The reason for this is that if generating space between plate 11 and electrode 14 in front, hand, hand
The detection accuracy of finger reduces.The partition 17 conductive partition 17 being configured between the back side of front panel 11 and electrode 14
Both it can deform, as a result, in the state of by certain distance is remained between the back side of front panel 11 and electrode 14, can fill
Between space.Partition 17 is formed by conductive material, so becoming and making the electrode 14 for detecting electrostatic capacitance change
The identical state of the back side of front panel 11 situation outstanding, can regard the back that front panel 11 is abutted to just like electrode 14 as
Face.In addition, if electrode 14 can be made seamlessly to cling to the back side of front panel 11, then can also be set as that partition 17 is omitted
Construction.
Next, illustrating the fixing means of front panel 11 and retainer 16.Fig. 9 is the back view of front panel.Before Figure 10 is
The magnified partial view of the lower backside of panel.In order to which front panel 11 can be removed in the construction of hand dryer 1, maintenance, and preceding
11 lower end of panel is provided with the (not shown) fitting portion fixed with framework 10.When removing front panel 11, make to be located at not shown
Fitting portion screw fluff after remove.In a manner of not generating gap between plate 11 and electrode 14 in front, plate in front
11 back side is provided with protrusion 41 in the part opposite with retainer 16.Moreover, being provided with clamping part in 16 side of retainer
42, when plate 11 inserts the protrusion 41 of front panel 11 in the state of being closed in front, which clamps front panel 11
Protrusion 41.
When being inserted into protrusion 41, clamping part 42 is flared by protrusion 41 and flexible deformation occurs, so as to
The distance of front panel 11 and electrode 14 is remained centainly.Moreover, protrusion 41 becomes maximum width in middle part, root
Partially the width of (that is, boundary part with front panel 11) attenuates compared with middle part.Therefore, inserted to clamping part 42 it is raised
When portion 41, stablize in the state that the front end of clamping part 42 is located at the root portion of protrusion 41, front panel 11 becomes by prominent
Play portion 41 and clamping part 42 and state that surface side of supporting or opposing always is pulled.It is not generated between plate 11 and electrode 14 in front as a result,
Space, so the operation in operation portion 12 is steadily detected.Moreover, in construction, maintenance, even if mistakenly forgetting to tighten spiral shell
Silk, will not generate gap between plate 11 and electrode 14 in front, can steadily detect the operation in operation portion 12.Moreover,
Even without screw, front panel 11 is also fixedly secured to framework 10, so can be improved application property without using screw.
Figure 11 is the figure for showing another structure example of operation portion.Omit the explanation about part same as Fig. 8.Electrode 14
It is made of retractile metal, such as spring or leaf spring in the longitudinal direction.About electrode 14, with the contact of front panel 11
Part and bigger with the area of the contact portion of operation substrate 15 and detection sensitivity is more preferable when plate thickness is thicker, it is advantageous to this
The electrode 14 of sample.
Figure 12 is the figure for showing the another structure example of operation portion.Omit the explanation about part same as Fig. 8.Operate base
