Description

Electronic machine

The present invention relates to an electronic device that inputs by contact of a user's finger or the like.

An electronic device that performs an operation input by contact is described in Japanese Laid-Open Patent Publication No. 2015-41223 and Japanese Patent Laid-Open No. 2013-65429. The electronic device described in Japanese Laid-Open Patent Publication No. 2015-41223 is an electrostatic switch. The electrostatic switch includes a base material panel that transmits light from a light source and forms an operation surface, a light shielding layer that has a light-shielding property and is partially formed with an opening for transmitting light from the light source, and diffuses and diffuses light from the light source. a layer and a detection mechanism for detecting the operation of the above-mentioned operation surface. In the above electrostatic switch, the light source is provided on a back surface side of the substrate panel, the light shielding layer, and the detecting mechanism. Further, in the light-emitting region provided on the operation surface, light from the light source is uniformly incident to accurately display the operation surface. The electronic device described in Japanese Laid-Open Patent Publication No. 2013-65429 is a capacitive touch sensor. The capacitive touch sensor has an illumination function, and includes an LED (Light Emitting Diode) (light source), a light guide plate, and an FPC (Flexible Printed Circuit) for arranging the same. . In the FPC, a through hole for extracting light from the light guide plate is provided. Further, an icon formed by printing or the like is disposed at a position facing the through hole of the surface panel. The light guide plate is disposed to overlap the through hole, and light emitted from the LED is incident from a side surface of the light guide plate, and light is emitted from a front surface of the light guide plate. Therefore, as the LED, a side-emitting type LED is used. Moreover, the light emitted from the light guide plate passes through the through hole to illuminate the icon from the back. Thereby, the user can accurately grasp the position of the icon on the surface panel and accurately perform touch input. The electrostatic discharge described in Japanese Laid-Open Patent Publication No. 2015-41223 relates to a configuration in which a light source is disposed on the back surface of the light-emitting region. In such a configuration in which a light source is disposed on the back surface of the light-emitting region, when a light source having a narrow irradiation area of light such as an LED is used, it is necessary to extend the distance from the light source to the light-emitting region in order to irradiate the entire light-emitting region with a sufficient amount of light. Therefore, it is difficult to miniaturize the electrostatic switch. Further, in the capacitive touch sensor described in Japanese Laid-Open Patent Publication No. 2013-65429, since the light guide plate having the light receiving surface on the side surface is used, it is possible to suppress the thickness of the device. However, in general, in the case of a capacitive touch sensor, in order to display information, it is necessary to use a back-illuminated LED and a side-illuminated LED. Further, in the back-illuminated LED and the side-emitting LED using the light guide plate, since the distance from the surface panel is different, they are mounted on the substrates provided at different positions. That is, two substrates are required for the LED. In these respects, the construction becomes complicated and the cost required for manufacturing becomes high.

Accordingly, it is an object of the present invention to provide an electronic apparatus having a simple configuration and capable of accurately detecting an operation input of an operating body. In order to achieve the above object, the present invention is an electronic device for operating an operation area provided on a surface panel, comprising: a substrate disposed on a back side of the surface panel; and a light source mounted on the substrate, having the above a light-emitting portion that emits light from the surface panel; a capacitance detecting portion that is attached to the substrate and detects an electrostatic capacitance between the operating body that contacts the surface panel; and a lens that has a concave surface and is disposed on a side opposite to the concave surface The light-emitting surface; wherein the concave surface faces the light-emitting portion, and the light-emitting surface is disposed to face the surface panel. According to this configuration, when light is irradiated from the back surface of the operation area and a display of characters, figures, or the like is performed, even if the LED having high directivity is used as the light source, the distance between the light source and the surface panel can be made short. Display of a wider operating area. Thereby, the electronic device can be miniaturized. Moreover, since the length of the change in electrostatic capacitance is detected, the length between the operator such as a finger and the capacitance detecting portion can be shortened, so that the contact or separation of the operating body can be accurately detected. In the above configuration, a conductive member that is in contact with at least one of the lenses and the capacitance detecting portion and has conductivity may be provided, and the conductive member may be elastically deformed. According to this configuration, the actual distance between the operating body such as the user's finger contacting the surface panel and the capacitance detecting portion can be shortened. Thereby, the contact or separation of the operating body can be accurately detected. In the above configuration, the fixing member for fixing the lens may be provided; the lens may have an inclined surface that is wider toward the operation region; and the support member may include the lens and at least partially contact the inclined surface to support a support portion of the lens; the support portion is a reflection surface for reflecting light. In the above configuration, the lens may be in close contact with the front surface panel. According to this configuration, it is possible to suppress the presence of air having a relatively low dielectric constant between the operating body such as the user's finger contacting the surface panel and the capacitance detecting portion. Thereby, the contact or separation of the operating body can be accurately detected. In the above configuration, the surface panel may be provided with a notification area having an area smaller than the area of the operation area and notifying the information; the light source includes a first LED that emits light toward the operation area, and the notification area is a second LED that emits light; and both the first LED and the second LED are mounted on the substrate. According to this configuration, it is possible to uniformly illuminate the operation area and the notification area having different sizes without changing the distance between the first LED and the second LED and the surface panel. Thereby, a plurality of substrates are not required for changing the distance or changing the irradiation direction, so that the structure can be simplified. According to the present invention, it is possible to provide an electronic apparatus having a simple configuration and capable of accurately detecting an operation input of an operating body.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. <First Embodiment> Fig. 1 is a front view of an air cleaner as an example of an electronic apparatus according to the present invention. Figure 2 is a rear view of the air cleaner shown in Figure 1. Fig. 3 is a cross-sectional view showing the air cleaner shown in Fig. 1 cut in the upper and lower middle portions. Fig. 4 is a cross-sectional view showing the air cleaner shown in Fig. 1 cut in the left and right middle portions. Figure 5 is a plan view of the air cleaner shown in Figure 1. In the following description, the upper and lower directions and the left and right directions are defined based on the direction of the air cleaner A shown in Fig. 1 unless otherwise specified. Further, the depth direction of the paper surface of Fig. 1 is referred to as the front-rear direction, and the front side of the paper surface is referred to as the front side. The air cleaner A includes a casing 10, a dust collector 20 disposed inside the casing 10, and a face portion 30 provided on the upper surface of the casing 10. The casing 10 is a member of the air cleaner A, and is a box member having a rectangular parallelepiped shape. The casing 10 has a suction port 11, a ventilation path 12, and an air outlet 13. As shown in FIG. 2, the suction port 11 is provided in the back surface of the casing 10. The suction port 11 has a rectangular shape and is an opening for sucking outside air into the inside of the casing 10. The ventilation path 12 is a space in which the air flow (air flow) generated by the driving of the blower 24 provided below to the dust collector 20 flows. The ventilation path 12 includes a branch portion 121 and a branch air passage 122. The branch air passages 122 are formed one by one at the left and right end portions of the inside of the casing 11. The branch portion 121 connects the left and right branch air passages 122. The branch portion 121 branches the air taken in from the suction port 11 toward the branch air passage 122 on the right and left sides. The air outlet 13 is provided on the left and right sides of the upper portion of the front surface of the casing 10. The air outlet 13 is connected to the branch air passage 122, and the air that has passed through the branch air passage 122 is blown out to the outside from the air outlet 13. Further, a grid-shaped grill 131 is attached to each of the right and left blow outlets 13. In the air cleaner A, the suction port 11, the ventilation path 12, and the air outlet 13 are connected in this order. Then, the air sucked into the inside of the casing 10 from the suction port 11 passes through the ventilation path 12, and is blown out from the air outlet 13 to the outside of the casing 10. In the air cleaner A, a dust collector 20 is provided inside the casing 10. The dust collector 20 includes a prefilter 21, a dust collecting filter 22, a dust removing unit 23, and a blower 24. The blower 24 is disposed in each of the left and right branch air passages 122. As shown in Fig. 3, the blower 24 is a centrifugal fan. However, it is not limited thereto, and a fan that can generate airflow can be widely used. An air motor (motor) (not shown) is connected to the blower 24, and an air flow is generated by driving the motor. The prefilter 21 is disposed inside the casing 10 and disposed to face the suction port 11. The prefilter 21 is formed of a synthetic resin such as ABS (Acrylonitrile-butadiene-styrene) resin, and is formed by a frame 211 having a rectangular shape in which the windows are vertically and horizontally arranged in a matrix. The screen 212 is formed. The screen 212 traps dust contained in the air taken in from the suction port 11. The dust collected by the prefilter 21 is removed (dust removed) by the dust removing unit 23. The dust removing unit 23 is disposed in an upper space inside the casing 10. The dust removing unit 23 includes a rotating brush 231, a dust collecting box 232, a guide frame 233, and a pinion 234. The dust removing portion 23 moves the prefilter 21 along the guide frame 233. The dust adhering to the prefilter 21 is removed by the rotating brush 231 and collected in the dust collecting box 232. The pinion gear 234 meshes with a rack (not shown) provided at the left and right side ends of the prefilter 21. The pinion gear 234 is rotated by a motor (not shown), and the pinion gear 234 is rotated, and the pre-filter 21 reciprocates between the dust collecting position P1 opposed to the suction port 11 and the retracted position P2 retracted to the dust removing portion 23. . At this time, the prefilter 21 is guided by the guide frame 233. The dust box 232 is disposed along the guide frame 233 and is detachable from the frame 10. On the back side of the casing 10, an opening portion 14 for taking out the dust collecting box 232 is provided. The rotating brush 231 is disposed inside the dust collecting box 232. The rotating brush 231 is rotated by a motor (not shown). Further, the motor that rotationally drives the rotating brush 231 and the motor that rotates the pinion 234 may be different motors, or may be a common motor. The rotating brush 231 includes a rotating shaft and bristles provided on the outer circumference of the rotating shaft. The bristle system is erected radially outward of the rotating shaft. When the pre-filter 21 moves from the dust collecting position P1 toward the retracted position P2, the rotating brush 231 rotates so that the moving direction of the tip end of the brush is opposite to the moving direction of the prefilter 21. Thereby, when the prefilter 21 moves from the dust collecting position P1 toward the retracting position P2, the dust collected on the surface of the prefilter 21 is removed by the bristles. The dust of the prefilter 21 removed by the rotating brush 231 is deposited on the dust collecting box 232. The dust removal by the prefilter 21 by the dust removing unit 23 can be performed periodically, for example, when the accumulated time of the air cleaning operation from the last dust removal reaches a certain time. Further, the sensor may be attached in advance, and the prefilter 21 may be performed when the pre-filter 21 is dirty to a certain extent or more. As the contamination of the prefilter 21 is detected, the prefilter 21 can be directly confirmed, and the amount of air passing through the prefilter 21 can be detected to detect the clogging of the prefilter 21. Further, when the dust removing unit 23 operates, the blower 24 is stopped. A dust collecting filter 22 is provided at a boundary portion between the branch portion 121 of the ventilation path 12 and the branch air path 122. In other words, the dust collecting filter 22 is provided on both the left and right sides so that the air flowing into the right and left branch air passages 122 is transmitted. The dust collecting filter 22 is, for example, a HEPA (High Efficiency Particulate Air) filter, but is not limited thereto. The dust collecting filter 22 has a filter material 221 and a frame member 222. The filter material 221 is a person who collects foreign matter such as dust passing through the air. The frame member 222 is formed of a resin, and the filter material 221 is fixed by heat fusion. Further, the filter material 221 is preferably bent into a corrugated shape (processed by pleating). Thereby, the filtration area of the filter material 221 can be increased. The gap of the filter material 221 is finer than the screen 212. That is, the dust collecting filter 22 can collect a smaller foreign matter (for example, PM2.5: fine particulate matter) than the prefilter 21. The dust collecting filter 22 is disposed upstream of a portion of the suction air of each of the left and right blowers 24. In the air cleaner A, a large foreign matter is collected by the prefilter 21, and the dust collecting filter 22 collects minute foreign matter that the prefilter 21 cannot collect. A deodorizing filter (not shown) having an adsorbent for adsorbing odor components (particles) contained in the air such as activated carbon may be provided between the prefilter 21 and the dust collecting filter 22. Thereby, the air can be deodorized by the odor component in the air being adsorbed by the adsorbent material. Further, an ion generator 15 that supplies ions to the airflow is provided in the ventilation path 12. For each of the branch air passages 122, the electrodes of the ion generator 15 face the inside of the branch air passage 122. The ion generator 15 generates positive ions and/or negative ions by applying a voltage of an alternating current waveform or a pulse waveform to the electrodes. For example, when the applied voltage of the electrode is a positive voltage, a positive ion containing H ⁺ (H ₂ O) m is mainly generated. In the case of a negative voltage, an anion containing O ₂ ^- (H ₂ O) n is mainly produced. Here, m and n are integers. H ⁺ (H ₂ O) m and O ₂ ^- (H ₂ O) n are agglomerated on the surface of the floating bacteria or ozone component in the air and coated. Further, as shown in the formulas (1) to (3), an active species, that is, [·OH] (hydroxyl radical) or H ₂ O ₂ (hydrogen peroxide) is agglomerated on the surface of microorganisms or the like by collision. And destroy the floating bacteria and so on. Here, m' and n' are integers. Therefore, the air cleaner A can perform sterilization and deodorization in the room by generating positive ions and negative ions and sending them out from the air outlet 13. A dust collecting sensor (not shown) and an odor sensor (not shown) are provided in the vicinity of the dust collecting filter 22. The dust sensor is composed of an optical sensor having a light-emitting element and a light-receiving element, and detects the concentration of dust in the air based on the output pulse width output from the light-receiving element. Moreover, PM2.5 and dust having a larger particle size than PM2.5 can be identified based on the pulse waveform of the output voltage of the dust sensor. For example, the pulse waveform of PM2.5 becomes a waveform having a gentle peak, and the pulse waveform of the dust having a larger particle diameter becomes a waveform having a sharp peak. Thereby, the concentration of PM2.5 in the air can be extracted from the detection result of the dust sensor. The odor sensor detects the concentration of the odor component in the air. The air cleaner A notifies the user of the information via the face portion 30 provided on the upper surface of the casing 10, or accepts an operation input from the user. Hereinafter, details of the face portion 30 will be described with reference to the drawings. 5 is a plan view of the air cleaner shown in FIG. 1, FIG. 6 is a schematic view of a face portion provided on the upper surface of the frame body, and FIG. 7 is a view showing a substrate in a state in which the lower surface case is removed. In FIG. 7, the buttons 31a to 31e and the display portions 32a to 32f are shown in a schematic shape for convenience of explanation. As shown in FIG. 5, in the air cleaner A, a dielectric surface portion 30 is provided on the upper surface of the casing 10. As shown in FIG. 6, the interface unit 30 includes an operation unit 301 that accepts an operation input from the user, and a notification unit 302 that notifies the state of the air cleaner A. Further, the operation unit 301 and the notification unit 302 of the interface unit 30 report the position or information to the user by the transmission of light emitted from the first LED 331 or the second LED 332 disposed inside. The interface surface 30 displays information by transmitting light emitted from the first LED 331 or the second LED 332 through the opening 344 provided in the light shielding member 342 described below. Details of this display are described below. The operation unit 301 has a plurality of buttons 31a to 32f, and the operation of the air cleaner A is set by the user's operation. The buttons 31a to 32f respectively perform operations for establishing a connection to the user by means of a graphic (i.e., an icon) or a character string. The setting of the timer operation is performed by the operation of the button 31a. For example, it is possible to determine when the power is turned on/off (ON/OFF) or when the power is turned on/off. Dust removal by the pre-filter 21 by the dust removing unit 23 is performed by the operation of the button 31b. The air volume of the blower 24 can be adjusted by the operation of the button 31c. The button 31d notifies the replacement timing of the dust collecting filter 23, and the resetting of the notification of the replacement period of the dust collecting filter 22 is performed by the operation of the button 31d. The button 31e notifies that the foreign matter accumulated in the dust box 232 has to be cleaned, and by the operation button 31d, the cleaning notification of the foreign matter by the button 31d is reset. The power supply of the air cleaner A is started or stopped by the operation of the button 31f, which is a so-called power button. Further, the buttons 31a to 31e cause the pattern and the characters to appear by the light provided in the opening 344 of the light shielding member 342 as described above. Therefore, the first LED 331 is disposed on the back surface of the buttons 31a to 31e. That is, the buttons 31a to 31e are not displayed when the power of the air cleaner A is turned off. On the other hand, since the button 31f is a power button, it must be visually recognized by the user regardless of whether the power of the air cleaner A is turned on or off. Therefore, the button 31f is formed on the surface panel 34 described below of the face portion 30. The button 31f is printable or may be a recess formed in the surface. This is set to print. The notification unit 302 has display units 32a to 32g that display the current state of the air cleaner A or the operation performed by the user. The display unit 32a is a so-called seven-segment display unit having seven sections for light emission. The display unit 32a displays characters such as numbers and letters by switching the light emission/non-light emission of the seven segments. Here, it is used to display the time when the timer is used, the current time, or the temperature. The display unit 32b displays a display unit of any of the "start timer" for turning on the power and the "suspension timer" for turning off the power after a predetermined time elapses. It becomes a so-called luminous text display. The display unit 32c notifies the state of the air around the air cleaner A. As the information to be notified, three items of "smell", "dust", and "PM2.5" are set, but the present invention is not limited thereto. Further, four indicators are provided for each display adjacent to the display of the characters. The indicator is turned on or off, and the status of each item is notified by the number of lights. Here, the information of the notified information "smell", "dust", and "PM2.5" is used as a light-emitting type, but it may be a printed matter. The display unit 32d lights up when the particle generator 15 is being driven. In FIG. 6, there is a text display which is omitted from the description. However, in the case where it is not particularly described, it may be an illuminated type of text display or a printed body. By setting it as an illuminated text display, when the power is turned off, the display of the surface of the face portion 30 can be hidden, thereby improving the design feeling. The display unit 32e notifies whether or not the input operation of the button 31b is locked. When it is lit, the notification button 31b is locked. The display unit 32f notifies the blower strength of the blower 24. For example, as the air supply intensity, "automatic", "strong", "medium", and "silent" are set, but the present invention is not limited thereto. For example, the display unit 32c may also indicate the air blowing intensity by the number of the illuminated indicators. The display unit 32f is an illuminated text display. Next, the details of the face of the electronic device of the present invention will be described. Fig. 8 is a cross-sectional view showing the operation portion of the face. Figure 9 is a cross-sectional view of the notification portion of the face. As described above, the face portion 30 transmits light from the back side and causes the display of the icon or the character string to emit light for display. As shown in FIG. 7, in the dielectric surface portion 30, a first LED 331 as a light source is disposed under each of the buttons 31a to 31e of the operation unit 301. Further, a second LED 332 as a light source is disposed below the display body of each of the display portions 32a to 32f of the notification unit 302 (for example, each segment of the display portion 32a or each indicator of the display portion 32c). As shown in FIGS. 6 and 7, the display range of each of the buttons 31a to 31e of the operation unit 301 is different from the size of the area where the display units 32a to 32f of the notification unit are displayed. Therefore, the operation unit 301 and the notification unit 302 have different configurations. In the interface 30, the operation unit 301 and the notification unit 302 have a common portion. Therefore, first, the common portion of the operation unit 301 and the notification unit 302 will be described. As shown in FIGS. 8 and 9, the dielectric surface portion 30 includes a substrate 33 and a surface panel 34. The substrate 33 is a commonly used printed wiring substrate. The surface panel 34 includes a diffusion member 341, a light shielding member 342, and a light transmitting member 343. The diffusion member 341 suppresses the variation in luminance (luminance unevenness) of the transmitted light by diffusing the incident light. Since the diffusion member 341 is a previously well-known member, the details thereof are omitted. The light shielding member 342 blocks light. Black is used as the light shielding member 342, but is not limited thereto. The surface panel 34 is provided with a light transmitting member 343 on the upper portion of the light shielding member 342. Therefore, when the surface panel 34 is viewed from the outside, the light shielding member 342 can be seen. That is, the surface panel 34 appears as the color of the light shielding member 342 when viewed from the outside. Here, since the light shielding member 342 is black, the dielectric surface portion 30 is black. Moreover, since the light shielding member 342 is black, the light from the outside can be blocked from the inside of the dielectric surface portion 30. Therefore, when the power of the air cleaner A is turned off, the buttons 31a to 31e and the display portions 32a to 32f other than the button 31f in the face portion 30 are not visible (blanking). The light shielding member 342 is provided with an opening 344. The light blocking member 342 passes light through the opening 344, and the other portion blocks light. Therefore, the opening 344 has an icon or a character string of the operation portion 301, a section of the notification portion 302, an indicator, and a character string. The light transmitting member 343 is formed of a material having a high light transmittance such as glass, an acrylic resin, or a polycarbonate resin. The surface panel 34 has a configuration in which the diffusing member 341 and the light transmitting member 343 are fixed to each other with the light blocking member 342 interposed therebetween. Further, the diffusion member 341, the light shielding member 342, and the light transmitting member 343 are followed by an adhesive having a high light transmittance. Thereby, since the adhesive is filled in the opening 344 of the light shielding member 342, formation of an air layer on the surface panel 34 can be suppressed. Further, the diffusion member 341 and the light shielding member 342 are not limited to this configuration, and a layer that diffuses light may be printed on the surface of the light shielding member 342. The configuration of the notification unit 302 will be described. The display units 32a to 32f of the notification unit 302 have the same configuration except for the size, the figure, or the character string. Therefore, the notification area 32 of the display unit will be described as a whole. In the notification unit 302, the second LED 332 is mounted on the substrate 33. Further, an opening 344 for forming a segment, an indicator or a character string is arranged in the notification area 32 of the notification unit. Further, the light emitted from the second LED 332 passes through the opening 344. Thereby, when the user observes the notification area 32 from the surface side of the light transmitting member 343, it can be seen that the display area 32, that is, the section, the indicator, or the character string is illuminated (elevated). To clearly display the segment, indicator or character string, the corresponding opening 344 is illuminated by the second LED 332 with uniform or substantially uniform light. Generally, since the LED has a narrow light distribution, the distance between the light-emitting surface of the second LED 332 and the surface panel 34 is a distance L. That is, the distance L between the substrate 33 and the surface panel 34 is determined by the light distribution angle of the second LED 332 and the size of the opening 344 disposed in the notification region 32. Further, although not shown, since the light shielding member covering the LED 332 and the opening 344 is provided between the LED 332 and the surface panel 34, it is possible to prevent light from the LED 332 from leaking from an unintended opening. Next, the configuration of the operation unit 301 will be described. First, the button 31f that does not perform the light-emitting display will be described. The button 31f is a power button, and an icon is printed without performing an illumination type display. The printing of the icon may be on the surface of the light transmitting member 343 or on the surface of the light transmitting member 343 opposite to the light blocking member 342. By printing the surface of the light-transmitting member 343 opposite to the light-shielding member 342, the user can accurately visually recognize the image, and the icon can be prevented from being worn away by use. Further, the electrostatic sensor 35 described below is disposed on the substrate 33 below the button 31f, and the following conductive member 36 that is in contact with each other is provided between the electrostatic sensor 35 and the surface panel 34. The conductive member 36 disposed on the button 31f may also have a solid cylindrical shape. The operation unit 301 is configured to perform illumination type display on each of the buttons 31a to 31e. The display of the light-emitting type of the buttons 31a to 31e has the same configuration except that the size, the figure, or the character string are different. Here, the operation area 31 will be described as a whole. Below the operation area 31, a first LED 331, an electrostatic sensor 35 (capacitance detecting unit), a conductive member 36, a lens 37, and a fixing member 38 are provided. Further, the substrate 33 and the front surface panel 34 (excluding the shape of the opening 344 of the light shielding member 342) are configured in common with the notification portion 302. The first LED 331 is mounted on a central portion of the portion of the substrate 33 corresponding to the operation region 31. A portion of the substrate 33 on which the first LED 331 is mounted forms a reflecting surface for reflecting light. Further, the reflecting surface may be a white surface, but is not limited thereto. The electrostatic sensor 35 is a sensor that detects the accumulated charge. The electrostatic sensor 35 and the operating body such as the finger of the user contacting the surface panel 34 constitute a capacitor, and the accumulated electric charge is detected based on the electric charge of the operating body. That is, the change in the electrostatic capacitance of the capacitor formed between the operating body and the operating body is detected. And, the contact or separation of the operating body with the surface panel 34 is detected based on the detection result. The electrostatic sensor 35 is mounted on the substrate 33 and has the same or substantially the same outer peripheral shape as the operation region 31. The first LED 331 is mounted on a central portion of a portion of the substrate 33 corresponding to the operation region 31. Therefore, the electrostatic sensor 35 has a circular ring shape (refer to FIG. 7). Furthermore, the electrostatic sensor 35 is only required to detect the degree of charge when the operating body contacts the surface panel 34. A lens 37 is provided above the first LED 331. The lens 37 is a so-called concave lens that expands the irradiation range of the light emitted from the first LED 331. The lens 37 includes a concave surface 371, an enlarged portion 372, and a light-emitting surface 373. The lens 37 is formed such that the concave surface 371 and the light-emitting surface 373 face in opposite directions. The enlarged portion 372 has a conical shape that increases in area as it approaches the light-emitting surface 373. A light-emitting surface 373 is formed at a maximum portion of the enlarged portion 372. The light-emitting surface 373 is formed to be the same size as the operation area 31 or larger than the operation area 31. That is, the light-emitting surface 373 has a size capable of accommodating the opening 344 therein in plan view. The lens 37 is fixed to the fixing member 38. The fixing member 38 has a mortar-shaped through hole 381, and the enlarged portion 372 of the lens 37 is in contact with the inclined surface 382 of the through hole 381 to hold the lens 37. Further, the lens 37 is also fixed by fixing the fixing member 38 to the surface panel 34. The fixing member 38 may be fixed to the surface panel 34 or may be substantially fixed by being fixed to the substrate 33 and abutting against the surface panel 34. Further, it is preferable that the lens 37 is in close contact with the surface panel 34 so that there is no air layer therebetween. Thereby, the detection sensitivity (accuracy) of the operation of the electrostatic sensor 35 can be improved. The inclined surface 382 of the through hole 381 is a structure that reflects light (for example, a structure having a white surface). Thereby, even if the light incident from the concave surface 371 leaks from the enlarged portion 372 to the outside, it is reflected by the inclined surface 382 and returned to the lens 37. Thereby, the light emitted from the first LED 331 can be utilized without waste. In order to accurately return the light leaking from the enlarged portion 372 to the lens 37, the surface of the enlarged portion 372 is preferably in close contact with the inclined surface 382, in other words, there is no air layer. In particular, when the lens 37 and the fixing member 38 are integrally molded, the air layer can be formed without interposing. There is a gap between the lens 37 or the fixing member 38 and the electrostatic sensor 35. If there is air having a relatively small dielectric constant in the portion, the electric charge accumulated in the electrostatic sensor 35 is reduced, resulting in a decrease in charge detection accuracy. . That is, it is difficult to detect contact or separation of the operating body with respect to the surface panel 34. That is, in order for the electrostatic sensor 35 to accurately detect that the operating body (finger) has contacted the surface panel 34, it is preferable that no air is interposed between the surface panel 34 and the electrostatic sensor 35. Therefore, the conductive member 36 is provided between the electrostatic sensor 35 and the lens 37 and the fixing member 38. The conductive member 36 is in contact with both the electrostatic sensor 35 and the lens 37. Further, the conductive member 36 is in contact with both the electrostatic sensor 35 and the fixing member 38. The conductive member 36 is an elastically deformable member, that is, a conductive bumper. Since the conductive member 36 is in contact with the electrostatic sensor 35, the capacitor formed by the operating body and the electrostatic sensor 35 can be replaced with a capacitor composed of the upper surface of the operating body and the conductive member 36. Between the conductive member 36 and the operating body, the surface panel 34, the lens 37, and the fixing member 38 are interposed but no air is present. Further, since the distance between the operating body and the conductive member 36 is shortened, the electrostatic sensor 35 can store a large amount of electric charge. Therefore, the contact or separation of the operating body can be accurately detected by the electrostatic sensor 35. Thus, by using the lens 37, the distance L between the substrate 33 and the surface panel 34 can be set in accordance with the notification region 32 having a narrow range of the illumination light, and the operation region 31 having a wider range to be irradiated can be provided at the same distance L. Light that emits less uneven brightness. Further, the substrate 33 can be made common by making the distance L between the substrate 33 and the surface panel 34 common to the operation region 31 and the notification region 32. Furthermore, by using the lens 37 and the conductive member 36, the icons and character strings of the operation area 31 can be uniformly displayed, and the operation input of the electrostatic sensor 35 can be accurately performed. Further, it is preferable that the concave surface 371 of the lens 37 is provided such that all of the light emitted from the first LED 331 is incident, in other words, covers the entire diffusion range of the first LED 331. Since the conductive member 36 is electrically conductive and elastically deformable, it is easy to absorb the color of black or near-black light in most cases. Therefore, by converging the entirety of the light emitted from the first LED 331 into the concave surface 371, it is possible to suppress the light emitted from the first LED 331 from being absorbed by the conductive member 36. Further, the concave surface 371 is formed in a portion of the central portion of the surface of the lens 37 opposed to the substrate 33. However, the concave surface 371 is not limited thereto, and the entire surface of the lens 37 opposed to the substrate 33 may be formed as a concave surface. Since the buttons 31a to 31e of the present embodiment are elastically deformable by the conductive member 36, the force applied when the user operates the buttons 31a to 31e can be dispersed. Thereby, the force acting on the first LED 331, the electrostatic sensor 35, the substrate 33, and the like can be eliminated or reduced. Thereby, it is possible to suppress defects such as breakage or malfunction caused by the operations of the buttons 31a to 31e. Further, the force applied when the user operates the button buttons 31a to 31e is also dispersed by the deformation of the surface panel 34 and the fixing member 38. <Second Embodiment> Another example of the electronic apparatus of the present invention will be described with reference to the drawings. Fig. 10 is a cross-sectional view showing another example of the operation portion of the face portion used in the electronic device of the present invention. The structure below the operation region 39 shown in FIG. 10 has the same configuration as that of the operation region 31 shown in FIG. 8 except that the shape of the lens 37 is different and the conductive member 36 is omitted. Therefore, the portions of the structure below the operation region 39 that are substantially the same as those of the operation region 31 are denoted by the same reference numerals, and the detailed description of the same portions will be omitted. As shown in FIG. 10, a lens 391 is provided below the operation area 39. The lens 391 includes a concave surface 392, a light-emitting surface 393, and a contact surface 394. Similarly to the concave surface 371 of the lens 37, the concave surface 392 is a light receiving portion that receives light emitted from the first LED 331. Further, the light-emitting surface 393 is a surface that emits light similarly to the light-emitting surface 373 of the lens 37, and is in close contact with the diffusion plate 341 of the surface panel 34. The contact surface 394 is adjacent to a concave surface 392 at a central portion of the contact surface 394 which is formed on a plane opposite to the light-emitting surface 393. That is, the contact surface 394 is a plane that surrounds the concave surface 392. The lens 39 has an enlarged portion 395, and one of the enlarged portions 395 is held by the fixing member 38. The fixing member 38 holds the lens 39 and is fixed to the surface panel 34, whereby the light-emitting surface 393 of the lens 39 is in close contact with the diffusion member 341 of the surface panel 34, and the contact surface 394 is in close contact with the electrostatic sensor 35. That is, between the operation body such as a finger that has contacted the surface panel 34 and the electrostatic sensor 35, the surface panel 34 and the lens 391 are interposed, but there is no air layer. Thereby, even if the conductive member is omitted, a sufficient charge can be accumulated in the electrostatic sensor 35. The contact of the operating body with the surface panel 34 can be accurately detected by the electrostatic sensor 35. Further, a conductive grease or the like may be applied between the contact surface 394 of the lens 39 and the electrostatic sensor 35 so as not to generate an air layer. Since the structure below the operation region 39 does not require a conductive member, the constituent members can be reduced. Further, in the present modification, the lens 391 is fixed by the fixing member 38. However, if the lens 39 is attached to the surface panel 34 and the electrostatic sensor 35 to suppress the shift of the lens 391, The fixing member 38 is omitted. Further, in the present modification, the lens 391 has a shape that expands toward the light-emitting surface 393, but is not limited thereto. For example, when the lens 391 is viewed in the axial direction orthogonal to the light-emitting surface 393, the shape of the light-emitting surface 393 may be the same as the shape of the contact surface 394. In the embodiment shown above, the lenses 37 and 391 have light-emitting surfaces 373 and 393 which are circular, and have a circular cross section perpendicular to the plane orthogonal to the light-emitting surfaces 373 and 393. However, it is not limited to this. For example, in the case where the shape of the button is a quadrangular shape, a lens matching the shape thereof can be used. In this case, the electrostatic sensor can also be set to match the shape of the button. A lens having a shape matching the shape of the button can be widely used. Further, even when the shape of the button is a shape other than a circle, the lens may be circular when viewed in the axial direction. In this case, as the light-emitting surface of the lens, a circular shape of the shape of the inner package button when viewed in the axial direction may be mentioned. Since the light-emitting surface is larger than the icon indicating the shape of the button, the opening can be uniformly or substantially uniformly illuminated, and an icon display with no difference or small difference can be realized. Moreover, the electrostatic sensor can also be circular. The electrostatic sensor and the button oppose each other in the axial direction, and form an operation body with the capacitor, and may have a shape and a size that can store a sufficient charge that can be detected. <Third Embodiment> Another example of the electronic apparatus of the present invention will be described with reference to the drawings. Fig. 11 is a perspective view of the humidifying air cleaner as another example of the electronic apparatus of the present invention as seen from the front side, and Fig. 12 is a cross-sectional view of the humidifying air cleaner shown in Fig. 11. In the following description, when it is called up, down, left and right, and before and after, the state shown in FIG. 11 is used as a reference. That is, the surface viewed from the left side of FIG. 11 is the front surface (front surface). Further, the left and right direction, the vertical direction, and the front and rear direction are defined toward the front side. The humidified air cleaner B shown in FIG. 11 includes a casing 40, a filter unit 50, a humidifying unit 60, a blowing unit 70, and an interfacial portion 80. The casing 40 includes a suction port 41 , a ventilation path 42 , a first air outlet 43 , a second air outlet 44 , a first louver 45 , a second louver 46 , and a baffle 47 . The suction port 41 is provided in an opening on the back surface of the casing 40. The outside air is sucked into the inside of the casing 40 from the suction port 41 by the driving of the blower unit 70. A filter unit 50 is attached to the inside of the suction port 41 so as to cover the suction port 40. The air taken in from the suction port 41 passes through the filter unit 50. The ventilation path 42 is a path through which air taken in from the suction port 41 passes. As shown in FIG. 12, the air taken in from the suction port 41 moves toward the front surface side and flows upward. The ventilation path 42 is branched in the middle, and one of them is connected to the first air outlet 43 provided on the upper surface, and the other is connected to the second air outlet 44 provided on the front surface. The first air outlet 43 and the second air outlet 44 blow the air flowing through the air passage 42 to the outside opening. The first louver 45 opens and closes the first air outlet 43. The first louver 45 can be stopped in a state of being opened at a specific angle from the position where the first outlet 43 is closed. The direction of the air blown from the first air outlet 43 can be changed (adjusted) by stopping the first louver 45. The second louver 46 is configured in the same manner as the first louver 45. The second louver 45 opens and closes the second air outlet 44. The second louver 46 can change (adjust) the direction of the air blown from the second blowing port 44. The baffle 47 distributes the air volume of the air flowing inside the ventilation path 42 to the first air outlet 43 and the second air outlet 44 in a specific ratio. By adjusting the opening and closing of the first louver 45, the second louver 46, and the baffle 47, the flow rate of the airflow blown from the first air outlet 43 and the second air outlet 44 is adjusted. An ion generator 48 is provided in the vicinity of the first blowing port 43 of the ventilation path 42. The ion generating electrode of ion generator 48 faces ventilation path 42. Further, since the details of the ion generator 48 are the same as those of the ion generator 15 included in the air cleaner A, detailed description thereof will be omitted. Further, in the present embodiment, the ion generator 48 is provided between the shutter 47 and the first air outlet 43, and supplies ions to the air blown from the first air outlet 43. However, the ion generator 48 may be disposed such that the ion generating electrode faces the upstream side of the baffle 47 facing the ventilation path 42. With this arrangement, air containing ions can be blown from both the first air outlet 43 and the second air outlet 44. The filter unit 50, the humidifying unit 60, and the air blowing unit 70 are disposed inside the ventilation path 42 in this order from the upstream of the flow direction of the airflow. Further, downstream of the flow direction of the air flow of the humidifying unit 60 of the ventilation path 42, an odor sensor 49 for detecting an odor component of the air is provided. The scent sensor 49 detects the odor component contained in the air that has passed through the humidifying unit 60. Next, the odor sensor 49 transmits a detection result to a control unit (not shown), and based on the detection result of the odor sensor 49, the control unit detects that the water supply body 63 from the humidifying unit 60 described below emits an odor. Next, the control unit notifies the user using the notification unit 802 of the following interface 80. By providing the scent sensor 49, the maintenance of the water supply body 63 that has been performed periodically can be performed at a time when it is necessary, in other words, when the water supply body 63 generates an odor, so that the maintenance of the water supply body 63 can be performed efficiently. The filter unit 50 is attached to the casing 51, and a prefilter, a deodorizing filter, and a dust collecting filter (none of which are shown) are disposed in order from the suction side of the air. A filter pressing member (not shown) is disposed between the prefilter and the deodorizing filter. Since the prefilter, the deodorizing filter, and the dust collecting filter are the same as those of the air cleaner A, the details are omitted. The blower unit 70 has a fan 71 and a motor 72. The fan 71 is here a centrifugal fan, but is not limited thereto, and a person who is designed to generate a flow of a predetermined flow rate can be widely used. The fan 71 is fixed to the drive shaft of the motor 72, and the fan 71 is rotated by the drive of the motor 72. The motor 72 is fixed to the housing 40. The details of the humidifying unit 60 will be described with reference to the drawings. Figure 13 is a perspective view of the humidifying unit. Figure 14 is a front elevational view of the water supply body employed in the humidifying unit shown in Figure 13. As shown in FIGS. 13 and 14, the humidifying unit 60 includes a water supply tank 61, a humidification tray 62, a water supply body 63, a frame 64, and a filter body 65. The humidifying unit 60 immerses the lower portion of the filter body 65 in the water in the humidifying tray 62 to allow water to pass through the filter body 65. And, the air is humidified by passing the airflow through the filter 65. Thereby, the humidified air is blown from the first air outlet 43 and the second air outlet 44. The humidification tray 62 is detachably attached to the casing 40, and the water supply tank 61 and the water supply body 63 are detachably attached to the humidification tray 62. Thereby, cleaning or maintenance of the humidifying unit 60 or the like can be easily performed. The water supply tank 61 is formed of a cylindrical container, and is formed, for example, by blow molding of a synthetic resin material such as PET (polyethylene terephthalate) or PP (polypropylene). An opening (not shown) is formed in one end surface of the water supply tank 61, and a valve mechanism (not shown) is provided. By providing the valve mechanism, even if the water supply tank 61 is turned upside down, the water inside is not leaked. Further, in the humidification tray 62, when the water stored in the humidification tray 62 is equal to or less than a fixed amount, the valve mechanism is scanned to allow the water in the tank 61 to flow into the humidification tray 62. The humidification tray 62 is formed in a substantially box shape in which the upper surface is open, and is formed of a resin molded article. The humidification tray 62 has a water supply body accommodating portion 621 that houses the water supply body 63, and a groove accommodating portion 622 that is adjacent to the water supply body accommodating portion 621 and houses the water supply tank 61. A partition plate 623 is provided between the water supply body accommodating portion 621 and the groove accommodating portion 622. The water supply body accommodating portion 621 is communicated with the groove accommodating portion 622 by the communication port 624 formed in the partition plate 623. The water supply body 63 includes a frame 64 and a filter body 65. The frame 64 has a cylindrical shape in which the axial end faces are horizontal. The frame 64 supports the filter body 65 by the radial pressing portions 641 disposed on both end faces of the axial direction. The pressing portion 641 is provided with an opening 642 through which the airflow passes, and the filter body 65 is exposed from the opening 642. The frame 64 is formed with an arcuate shielding portion 643 at one of the end faces of the axial direction. On the circumferential surface of the frame 64, a rack 644 is formed. The rack 644 is meshed with a pinion (not shown) that is attached to a motor (not shown). The pinion is rotated by a motor. Thereby, the water supply body 63 can be rotated in the vertical plane. By the water supply body 63 rotating in the vertical plane, a part of the filter body 65 held by the frame body 64 is immersed in the water stored in the water supply body accommodating portion 621. When one of the filter bodies 65 is partially immersed in water, water is sucked up by the capillary phenomenon and the water spreads over the entire filter body 65. In this state, the airflow is supplied to the opening 642, and moisture is supplied to the airflow to be humidified. Then, by rotating the water supply body 63 intermittently, the state of the water throughout the entire filter body 65 can be maintained. Thereby, the air flow can be stably humidified. Thereby, the so-called humidifying and purifying operation can be performed, that is, the air collected by the filter unit 50 is humidified and blown out to the outside. When the shielding portion 643 of the casing 64 is disposed at the lower end to stop the rotation of the water supply body 63, the filter body 65 is shielded from the water in the storage water supply tray 621 by the shielding portion 643. In this state, the filter body 65 is dried by passing the airflow through the filter body 65 through the opening 642 for a fixed period of time. Thereafter, in a state where the rotation of the water supply body 63 is stopped, only the dust collecting operation of the filter unit 50 is performed by generating the air current, that is, the so-called air clearing operation is performed. The filter body 65 will be described with reference to the drawings. Figure 15 is a perspective view showing a portion of the enlarged filter body. The filter body 65 is formed of a nonwoven fabric or the like which has air permeability and water absorbability. The filter body 65 is bent into a corrugated shape (wrinkled), and the fixing material 651 is disposed in a bead shape. The fixing material 651 is formed of an elastically deformable material. The fixing material 651 maintains the filter body 65 in a pleated shape. The fixing material 651 is here a porous body having an infinite number of cavities inside. The fixing material 651 is a mixture of a molten resin (a hot-melt adhesive such as a polyolefin resin) mixed with a gas (for example, nitrogen gas) to be solidified before being vented to form a cavity inside. The filter body 65 is attached to the sheet, and a gas is mixed into the hot-melt adhesive, and the sheet constituting the filter body 65 is applied in a line shape. Next, the sheet is bent in the direction of the hot melt adhesive before the hot melt adhesive is cured. Thereby, the hot melt adhesives are followed by each other. Further, the hot-melt adhesive which is internally mixed with the gas is hardened to become a fixing material 651 in which a portion of the gas is present as a cavity. The filter body 65 formed of the fixing material 651 in a pleated shape has a larger axial width than the frame 64. Thereby, when the filter body 65 is attached to the frame 65, the filter body 65 is pressed against the pressing portion 641 of the frame 64, and the filter body 65 is hard to be bent or bent. Furthermore, the fixing material 651 can also contact the pressing portion 641. Since the fixing material 651 is elastically deformable, the fixing member 651 can be firmly held by the pressing portion 641. Fig. 16 is a schematic view showing a face portion provided on the upper surface of the casing. As shown in FIG. 16, the interface 80 has an operation unit 801 and a notification unit 802. The operation unit 801 has buttons 81a to 81j. The buttons 81a to 81j are associated with the operation of the humidified air cleaner B, respectively, and each operation is performed by pressing the buttons 81a to 81j. The buttons 81a to 81j have the same configuration as the buttons 31a to 31e, although they are different in operation. Therefore, the detailed description is omitted. The notification unit 802 has display units 82a to 82h. The display units 82 to 81g respectively display information of the humidified air cleaner B. The display units 82a to 82h have the same structure as the display units 32a to 32f although the notified contents are different. Therefore, the detailed description is omitted. In the embodiment described above, the air cleaner and the humidified air cleaner are exemplified as the electronic device, and examples thereof include a refrigerator, a washing machine, a heating conditioner, and an audio device. Further, the electronic device is not limited to the above device. An electronic device including an intervening face having an operation portion that is operated by contact of an operator such as a user's finger, and displaying the shape or the area of the operation region by illumination The operation establishes a related text or graphic (icon); and the notification department notifies the information by illumination. [Related application] The present application is based on Japanese Patent Application No. 2015-215556, filed on Nov. 2, 2015.
