When the operating device is used as a wiring device and is embedded in a hole provided in a building surface such as a wall of a building, the operating device is required to be miniaturized. In order to reduce the size of the operating device, a single-polarized antenna (inverted F-type antenna) that is easy to reduce in size is used as the antenna. However, if the ground element does not have a size larger than half a wavelength, high-frequency current distribution will also occur in the power supply wiring. If an operating device equipped with such an inverted F-shaped antenna is constructed, high-frequency current may even flow across the power circuit and radiate to the power wiring. For this reason, the radiated electric field from the antenna is combined with the radiated electric field from the power supply wiring, causing the directivity of the antenna to become a deformed shape.

The present invention was developed in view of this situation, and its purpose is to provide a technology that can make the directivity of the antenna approach omnidirectional even if the operating device is miniaturized.

In order to solve the above-mentioned problems, an operating device according to one aspect of the present invention has a first surface and a second surface facing opposite sides of each other. The operating device includes: an operating portion disposed on the first surface side; and a power supply. part is arranged on the second surface side and is connected to the power supply wiring; and a control substrate is arranged between the operation part and the power part and is extended along at least one of the first surface and the second surface. The operation part accepts operations; the power supply part performs power supply from the power supply to the load through the power wiring in response to the operation accepted by the operation part; a folded dipole antenna that can be used for wireless communication is arranged on one side of the control substrate.

Another aspect of the present invention is a wiring device. This wiring device is fixed to the installation surface; this wiring device has: an operating part that accepts user operations; a first antenna that constitutes a folded dipole antenna and is used in the first frequency band; and a second antenna that is used in a frequency band higher than the first Band 2 of the frequency band.

According to the present invention, even if the operating device is miniaturized, the directivity of the antenna can be made close to omnidirectional.

Before describing the embodiments of the present invention in detail, an overview of the embodiments will be described first. The embodiment relates to a wiring system including a two-wire operating device for controlling a load. An example of the load is a lighting load. The user can switch the lighting load on and off by operating the operating part of the operating device. Or control the dimming of lighting loads. In order to display lighting scenarios by controlling multiple lighting loads at the same time, the operating device needs to be linked with other operating devices. In order to realize linkage between multiple operating devices, each operating device is equipped with a wireless communication function. Furthermore, if the operating device is equipped with a wireless communication function, the operating device can also connect to the Internet through a gateway (GateWay) device to perform remote operations or obtain the provision of other services.

As mentioned above, when the operating device uses an inverted F-type antenna in order to reduce the size of the operating device, the radiated electric field from the antenna will be combined with the radiated electric field from the power supply wiring, causing the directivity of the antenna to become a deformed shape. . If the directivity of the antenna becomes a deformed shape, the wireless communication distance will become shorter. When an area network is to be formed between multiple operating devices, the directivity of the antenna is preferably close to omnidirectional. In order to cope with this, the operating device of this embodiment is equipped with a folded dipole antenna for wireless communication. Since the high-frequency current is enclosed in the loop in the folded dipole antenna, the impact of the power wiring on the directivity is reduced. In the following explanation, "parallel" and "perpendicular" do not only mean completely parallel or perpendicular, but also include deviations from parallel or perpendicular within the error range. Furthermore, "approximately" means approximately the same within this range.

Figure 1 illustrates the structure of a wiring system 1000. The wiring system 1000 includes: the first power line 10a and the second power line 10b, collectively called the power line 10; the first power wiring 20a, the second power wiring 20b, and the third power wiring 20c, collectively called the power wiring 20; and collectively called the lighting load 30 The first lighting load 30a and the second lighting load 30b; the terminal device 50; and the first operating device 100a and the second operating device 100b are collectively referred to as the operating device 100. Here, the number of combinations of the lighting load 30 and the operating device 100 is "2", but it is not limited to this. The number of terminal devices 50 is "1", but it is not limited to this.

The power line 10 is connected to, for example, a single-phase 100 [V], 50 or 60 [Hz] AC power supply (not shown) to transmit AC power. The AC power supply can be commercial power provided by electric power companies and other power operators, but it can also be self-use power generation equipment such as solar power generation equipment. The first power line 10a and the operating device 100 are connected by the first power wiring 20a, the operating device 100 and the lighting load 30 are connected by the second power wiring 20b, and the lighting load 30 and the second power line 10b are connected by the third power wiring 20c. That is to say, the operating device 100 and the lighting load 30 are connected one-to-one, and these combinations are extended and connected to the power line 10 through the first power supply wiring 20a to the third power supply wiring 20c. Here, the combination of the first operating device 100a and the first lighting load 30a, and the combination of the second operating device 100b and the second lighting load 30b are connected to the power line 10 in the same manner.

The operating device 100 is, for example, a wiring device. The operating device 100 is fixed to the installation surface with its rear part embedded in a buried hole provided in the installation surface of a wall or the like. The operating device 100 is not limited to the embedded type structure. It may also have an exposed type structure that is directly installed on the installation surface, or a structure that is not fixed at a fixed position and can be used in any place. The two-wire operating device 100 is electrically connected to the AC power supply in series with the lighting load 30 . The user operates the operating device 100 in order to turn on, turn off, and dim the lighting load 30 . The operating device 100 has a load control function, and controls the current flowing to the lighting load 30 in response to operations received from the user, so that the lighting load 30 turns on (full light or dimmed light) or turns off the light. The lighting load 30 will turn on when powered. The lighting load 30 includes a light source such as an LED (Light Emitting Diode), and a lighting circuit for lighting the light source.

Each operating device 100 has a wireless communication function configured by, for example, low-power wireless (specific low-power wireless) using radio waves in the 920 MHz band or the 420 MHz band. As an example here, it is assumed that the device has a wireless communication function based on a specific low-power wireless in the 920 MHz frequency band. Each operating device 100 can communicate with each other through specific low-power wireless communication. In FIG. 1 , the specific low-power wireless system is labeled as the first wireless communication 60 .

Once the first operating device 100a accepts an operation from the user, the first operating device 100a controls the lighting of the first lighting load 30a in response to the operation. Furthermore, the first operating device 100a will use the first wireless communication 60 to send a wireless signal showing the operation content to the second operating device 100b. The second operating device 100b will control the lighting of the second lighting load 30b according to the operation content presented by the received wireless signal. As a result, when the user operates the first operating device 100a, the first lighting load 30a and the second lighting load 30b are lit in the same manner. The first operating device 100a can also send a wireless signal to an operating device 100 other than the second operating device 100b, and the second operating device 100b can further forward the wireless signal received from the first operating device 100a to another operating device. 100. This allows three or more lighting loads 30 to light up in the same manner.

Each operating device 100 also has a wireless communication function based on a communication standard of short-range wireless communication such as BLE (Bluetooth Low Energy (registered trademark)). Furthermore, the terminal device 50 is, for example, a smartphone, a tablet terminal device, or a personal computer, and can perform short-range wireless communication such as BLE. Therefore, the operating device 100 and the terminal device 50 can communicate through short-range wireless communication. In FIG. 1 , the short-range wireless communication system is marked as the second wireless communication 62 .

When the user operates the application program executed on the terminal device 50, the terminal device 50 sends a wireless signal showing the operation content of the first lighting load 30a to the first operating device 100a through the second wireless communication 62. No. The first operating device 100a will control the lighting of the first lighting load 30a according to the operation content presented by the received wireless signal. Since the frequency band used in specific low-power wireless (hereinafter referred to as the "first frequency band") is the 920MHz frequency band, and the frequency band used in BLE (hereinafter referred to as the "second frequency band") is the 2.4GHz frequency band, the second frequency band is higher in band 1.

FIG. 2 is a perspective view showing the appearance of the operating device 100 . As shown in Figure 2, the orthogonal coordinate system composed of the x-axis, y-axis, and z-axis is determined. The x-axis and y-axis systems are orthogonal to each other. The z-axis is perpendicular to the x-axis and the y-axis, and extends in the height direction of the operating device 100 . Furthermore, the positive direction of each of the x-axis, y-axis, and z-axis is set to the direction of the arrow in Figure 2, and the negative direction is set to the opposite direction to the arrow. Sometimes the positive direction of the z-axis is called "upper" or "upper side", and the negative direction of the z-axis is called "lower" or "lower side". Sometimes the positive direction of the x-axis is called "front" or "front", and the negative direction of the x-axis is called "rear" or "rear side". Sometimes the positive direction of the y-axis is called "right" or "right", and the negative direction of the y-axis is called "left" or "left". Therefore, the z-axis is an axis extending in the up-down direction, the x-axis is an axis extending in the front-rear direction, and the y-axis is an axis extending in the left-right direction.

The operation part will accept the user's operation and control the load. A rectangular opening is provided in the center of the rear side of the module box 210 . The control substrate 500 and the relay substrate 420 are electrically connected through the opening. Board body 200 and component box 210 is made of an insulating material such as resin, PBT (Polybutylene terephthalate; polybutylene terephthalate) resin or the like.

The switch frame 300 is installed on the component box 210 from the rear side. The switch frame 300 is used to embed the operating device 100 in a buried hole provided in a mounting surface such as a wall. The switch frame 300 is a fixed installation frame fixed to the installation surface. The switch frame 300 is made of metal, for example. On the switch frame 300, the body 400 is installed from the rear side. The body 400 has a box shape, and a rectangular second surface 120 is arranged on the rear side of the body 400 . The second surface 120 of the body 400 is provided with a through hole (not shown) for passing the first power supply wire 20a and the second power supply wire 20b. The first power supply wire 20a and the second power supply wire 20b are connected to the body 400. is internally connected to the power supply (not shown). Therefore, the power supply unit is arranged on the second surface 120 side. Furthermore, the first surface 110 and the second surface 120 face opposite sides to each other.

FIG. 3 is an exploded perspective view showing the structure of the operating device 100 . The plate body 200 arranged on the frontmost side has the first surface 110 as mentioned above, and the opening 202 is provided in the center of the first surface 110 . A plate-shaped touch panel 220 is arranged on the rear side of the opening 202 , and a plate-shaped display panel 230 is arranged on the rear side of the touch panel 220 . The display panel 230 is, for example, electronic paper or a liquid crystal display, and displays a screen for urging the user to perform operations. The so-called screen that urges the user to perform an operation refers to a screen that presents operation objects such as a light-on button, a light-off button, or a dimmer knob. Once the user operates an operation object such as a light-on button, a light-off button or a dimming knob displayed on the display panel 230, the touch panel 220 will accept the operation performed by the user's finger. In the operating device 100, the display panel 230 can also be omitted.

On the rear side of the display panel 230, a plate-shaped control substrate 500 is arranged through a frame-shaped gap (not shown). The control substrate 500 is also called a first substrate. The gap is formed of an insulating material such as resin. The touch panel 220 and the display panel 230 will be fixed inside the housing composed of the combination of the panel 200 and the component box 210 through the spacer and the panel 200 . The control substrate 500 is disposed between the touch panel 220 and the power supply unit (not shown), and extends along at least one of the first surface 110 and the second surface 120 . In addition, the front side surface of the control substrate 500 is the first surface 510 and the rear side surface of the control substrate 500 is the second surface 512 . The control circuit board 500 is equipped with a control circuit for controlling the display on the display panel 230 (hereinafter referred to as "display control circuit"). The display control circuit is connected to the display panel 230 . Furthermore, the control circuit board 500 is also equipped with a control circuit for controlling wireless communication (hereinafter referred to as a "wireless communication control circuit") and an antenna. The structure of the control substrate 500, especially the structure of the antenna, will be described later. On the rear side of the control board 500, the component box 210 is arranged. In this way, the control board 500 and the like arranged between the board body 200 and the component box 210 are arranged inside the housing composed of the combination of the board body 200 and the component box 210 .

On the rear side of the component box 210, the switch frame 300 is arranged; on the rear side of the switch frame 300, a rear side cover (not shown) is arranged. The rear side cover seals the box-shaped body 400 with an open front side from the front side. In the internal space of the body 400 formed by the combination of the rear cover and the body 400, a relay substrate 420, an insulating sheet 430, and a power substrate 440 are arranged in order from the front side to the rear side. Furthermore, the rear cover may not be provided, and the component box 210 can be used to seal the box-shaped body 400 with an open front side from the front side. In this case, in the internal space of the body 400 formed by the combination of the component box 210 and the body 400, the relay substrate 420, the insulating sheet 430, and the power substrate 440 are arranged in order from the front side to the rear side. The rear cover and body 400 are made of insulating material such as resin, made of PBT (Polybutylene terephthalate; polybutylene terephthalate). diester) resin, etc. The relay substrate 420 is equipped with a control circuit (hereinafter referred to as "operation control circuit") for controlling operations in response to operations received on the operation unit (touch panel 220). The operation control circuit is connected to the operation unit (touch panel 220) via the control substrate 500 and the like. The relay substrate 420 is also called a second substrate; the power supply substrate 440 is also called a third substrate.

The power supply board 440 corresponds to the power supply section described above, and is connected to the first power supply wiring 20a and the second power supply wiring 20b in FIG. 2 . The power supply board 440 is equipped with: a power circuit that converts the voltage of 100 V of AC power received from the power wiring 20 into a voltage of 5 V used in the operating device 100; and a circuit that performs operation in response to control from the operation control circuit. Dimming of lighting load 30. That is to say, the power substrate 440 will perform power supply from the AC power source to the lighting load 30 via the power wiring 20 in response to the operation received on the touch panel 220 . On the rear side of the power substrate 440, there are connection terminals connected to the power wiring 20. The connection terminals are arranged in the internal space of the machine body. The connection terminals may also be soldered to the rear side of the power substrate 440 . The connection terminal is formed of metal, for example. The insulating sheet 430 is arranged so that at least part of it overlaps the connection terminal when viewed from above in the X-axis direction. The power supply circuit includes, for example, a plurality of electronic components constituting an AC/DC converter that converts AC power supplied from an external AC power supply via a connection terminal into DC power of a predetermined voltage. Plural electronic components, such as transformers, capacitors or resistors, etc. Transformers, capacitors, resistors, etc. are, for example, soldered to the rear side of the power supply substrate 440 . In this case, the influence of heat or electromagnetic fields generated by electronic components such as transformers, capacitors, resistors, etc. on the antenna, display control circuit, wireless communication control circuit, operation control circuit, etc. can be suppressed.

The antenna provided on the control substrate 500 will be described below. However, as a premise, in order to clarify the issues related to the antenna, the control substrate 600 as a comparison target of the control substrate 500 will first be described. The control substrate 600 is, for example, disposed in the operating device 100 in place of the control substrate 500 . 4(a) to (c) illustrate the structure of the control substrate 600 of the comparison object and the directivity formed by the inverted F-shaped antenna 630. Figure 4(a) shows the structure of the control substrate 600; the first surface 610 and the second surface 612 of the control substrate 600 correspond to the first surface 510 and the second surface 512 of the control substrate 500. On the second surface 612, the ground element 620 and the inverted F-shaped antenna 630 are mounted. The inverted F-shaped antenna 630 is used as an antenna for specific low-power radio using the first frequency band. Since the ground element 620 and the inverted F-shaped antenna 630 are well-known technologies, their description is omitted here.

Figure 4(b) shows the directivity of the inverted F antenna 630 alone. As shown in the figure, the individual directivity of the inverted F-shaped antenna 630 is close to omnidirectional. FIG. 4( c ) shows the directivity of the inverted F-shaped antenna 630 including the power wiring 20 . In order to achieve miniaturization of the operating device 100, the size of the first surface 610 is limited. Furthermore, the size of the inverted F-shaped antenna 630 depends on the frequency band used, such as the 920MHz frequency band. In this case, the ground element 620 may not be of sufficient size. If the ground element 620 is not large enough, current distribution will occur in all connected ground elements 620 due to the inverted F-shaped antenna 630 . The high-frequency current generated in this way may even spread and radiate to the power wiring 20 via the relay substrate 420 and the power substrate 440 . As a result, the radiation electric field from the inverted F-shaped antenna 630 is combined with the radiation electric field from the power supply wiring 20, and the directivity becomes a deformed shape as shown in FIG. 4(c).

In order to make the antenna directivity when including the power wiring 20 approach omnidirectionality, the antenna of this embodiment is as shown in FIGS. 5(a) to (c) . 5(a) to (c) illustrate the structure of the control substrate 500 and the directivity formed by the folded dipole antenna 550. Figure 5(a) illustrates the structure of the control substrate 500; On the second surface 512, the ground element 520 and the folded dipole antenna 550 are arranged. The folded dipole antenna 550 can be made of metal or the like and formed as a pattern on a printed circuit board, or it can be made of metal or the like and separately made and then pasted.

The folded dipole antenna 550 is also called the first antenna. The first antenna is, for example, a dipole antenna. The first antenna is an antenna for the first frequency band. The folded dipole antenna 550 is used as an antenna for specific low-power radio using the first frequency band. The loop-shaped element forming the folded dipole antenna 550 includes a first element portion 540 and a second element portion 542 that are different from each other. The first part 540 of the component extends from the first connection point 530 to the first turning point 532 while bending, and then returns to the intermediate point 534 while bending from the first turning point 532 . The second part 542 of the component extends from the middle point 534 to the second turning point 536 while bending, and then returns to the second connection point 538 while bending from the second turning point 536 . Here, the first connection point 530 , the first return point 532 , the intermediate point 534 , the second return point 536 , and the second connection point 538 are arranged near the center of the second surface 512 in the left-right direction. Furthermore, the length from the first connection point 530 to the first turning point 532, the length from the first turning point 532 to the intermediate point 534, the length from the intermediate point 534 to the second turning point 536, the length from the second The length from the return point 536 to the second connection point 538 is approximately 1/4 wavelength.

Figure 5(b) presents the directivity of the folded dipole antenna 550 alone. As shown in the figure, the individual directivity of the folded dipole antenna 550 is close to omnidirectional. Figure 5(c) shows the directivity of the folded dipole antenna 550 including the power wiring 20. The directivity shown in Figure 5(c) is closer to omnidirectional than the directivity shown in Figure 4(c). This is because in the folded dipole antenna 550, the high-frequency current is enclosed in the dipole antenna, so the influence of the power wiring 20 on the directivity is reduced. The folded dipole antenna 550 in FIG. 5(a) is mounted on the second surface 512 facing the second surface 120 of the control substrate 500 . This is to reduce the influence of fingers operating the touch panel 220 .

FIG. 6 shows another structure of the control substrate 500. The second surface 512 of the control substrate 500 includes a first side 514 extending in the left-right direction and a second side 516 extending in the up-down direction. Side 2 516 is longer than side 1 514. On such second surface 512, the ground element 520 and the folded dipole antenna 550 are arranged. The ground element 520 and the folded dipole antenna 550 may also be disposed on the first surface 510 of the control substrate 500 . The first part 540 of the component extends from the first connection point 530 to the first turning point 532 while bending, and then returns to the intermediate point 534 while bending from the first turning point 532 . In particular, in the element first portion 540, the portion arranged along the first side 514 without bending is made longer than the portion arranged along the second side 516 without bending. At least part of the element first portion 540 is arranged along the first side 514 of the control substrate 500 . At least part of the first part of the device is arranged along the second side 516 of the control substrate 500 . At least part of the element first portion 540 is arranged along the fourth side opposite to the second side of the control substrate 500 .

On the other hand, the second part 542 of the element extends from the intermediate point 534 to the second return point 536 while being bent, and then returns to the second connection point 538 while being bent from the second return point 536 . In particular, in the element second portion 542, the portion arranged along the second side 516 without bending is made longer than the portion arranged along the first side 514 without bending. In other words, the first component part 540 is mainly arranged along the first side 514 , and the second component part 542 is mainly arranged along the second side 516 . The same applies here, the length from the first connection point 530 to the first return point 532, the length from the first return point 532 to the intermediate point 534, the length from the intermediate point 534 to the second return point 536, and the length from the intermediate point 534 to the second return point 536. The length from the second return point 536 to the second connection point 538 is approximately 1/4 wavelength. At least part of the second part 542 of the element is arranged along the second side 516 of the control substrate 500 . At least part of the element second portion 542 is arranged along the third side facing the first side 514 of the control substrate 500 . The length of the second part 542 of the component along the second side 516 is greater than the length of the first part 540 of the component along the fourth side. length. The length of the first part 540 of the component along the first side 514 is greater than the length of the second part 542 of the component along the third side.

On the second surface 512, a wireless communication control circuit (hereinafter referred to as the "first wireless communication control circuit 570") is disposed for performing wireless communication using the folded dipole antenna 550.

Furthermore, the first wireless communication control circuit 570 may also be disposed on the first surface 510 . When the folded dipole antenna 550 and the first wireless communication control circuit 570 are disposed on different surfaces of the control substrate, the first wireless communication control circuit 570 is connected to the folded dipole antenna 550 through a through hole provided in the control substrate 500. Dipole Antenna 550.

The inverted F-shaped antenna 560 is also called the second antenna. The second antenna is, for example, a monopole antenna. The second antenna is an antenna for the second frequency band. The inverted F-shaped antenna 560 can be disposed on the second surface 512 of the control substrate 500 or on the first surface 510 . A notch area 522 is provided in a part of the ground element 520, and an inverted F-shaped antenna 560 is mounted on the notch area 522. The inverted F-shaped antenna 560 is used as an antenna for BLE using the second frequency band. Since the second frequency band is higher than the first frequency band, the inverted F-shaped antenna 560 is smaller than the folded dipole antenna 550 . Therefore, for the inverted F-shaped antenna 560, the size of the ground element 520 is sufficient, so the directivity of the inverted F-shaped antenna 560 is not easily affected by the power supply wiring 20. On the first side 510, a wireless communication control circuit (hereinafter referred to as the "second wireless communication control circuit 572") is disposed for performing wireless communication using the inverted F-shaped antenna 560. When the inverted F-shaped antenna 560 and the second wireless communication control circuit 572 are disposed on different surfaces of the control substrate, the second wireless communication control circuit 572 passes through a through hole (not shown) provided in the control substrate 500 ) is connected to the inverted F antenna 560.

Furthermore, it may also be arranged along the third side facing the first side 514 of the control substrate 500 . The second antenna can be a dipole antenna or a folded dipole antenna. The inverted F-shaped antenna 560 can be made of metal or the like and formed on the printed circuit board as a pattern, or it can be made of metal or the like and separately made and then pasted. The length of the inverted F-shaped antenna 560 along the fourth side is smaller than the length of the second portion 542 of the element along the second side 516 . The first antenna and the second antenna are arranged in an area along the periphery of the first substrate. The length of the second antenna along one side of the first substrate is smaller than the length of the first antenna along the other side opposite to one side of the first substrate. By adopting this structure, the device can be miniaturized.

Figures 7(a)~(b) show the directivity formed by the folded dipole antenna 550. Figure 7(a) presents the directivity of the folded dipole antenna 550 alone. As shown in the figure, similar to Figure 5(b), the individual directivity of the folded dipole antenna 550 is close to omnidirectional. FIG. 7( b ) shows the directivity of the folded dipole antenna 550 including the power wiring 20 . The directivity shown in Figure 7(b) is closer to omnidirectional than the directivity shown in Figure 5(c). This is due to the fact that the elements are further linearized, so the antenna efficiency is improved.

According to this embodiment, since the folded dipole antenna 550 is used in the operating device 100 connected to the power wiring 20, the high-frequency current is enclosed in the dipole antenna, thereby reducing the directivity of the power wiring 20. influence. Furthermore, since the influence of the power wiring 20 on the directivity is reduced by confining the high-frequency current in the loop, the directivity of the antenna can be made close to omnidirectional even if the operating device 100 is miniaturized. . Furthermore, since the first element portion 540 of the folded dipole antenna 550 is arranged along the first side 514 and the second element portion 542 is arranged along the second side 516, the elements can be formed in a linear shape. Again Furthermore, since the elements are arranged in a linear shape, the antenna efficiency can be improved. Furthermore, since the antenna efficiency will be improved, the directivity of the antenna can be further closer to omnidirectional.

Furthermore, since the first wireless communication control circuit 570 and the folded dipole antenna 550 are disposed on the same surface, the distance between the first wireless communication control circuit 570 and the folded dipole antenna 550 can be shortened. Furthermore, since the distance between the first wireless communication control circuit 570 and the folded dipole antenna 550 will be shortened, the transmission loss can be reduced. Furthermore, since the folded dipole antenna 550 is used for wireless communication with other operating devices 100, communication between the operating devices 100 can be realized.

Furthermore, since the folded dipole antenna 550 used for wireless communication in the first frequency band and the inverted F-shaped antenna 560 used for wireless communication in the second frequency band are arranged, two types of wireless communication can be performed. Furthermore, since the first wireless communication control circuit 570, the folded dipole antenna 550 and the inverted F-shaped antenna 560 are arranged on the same side, and the second wireless communication control circuit 572 is arranged on the other side, these arrangements can be on the control substrate 500. Furthermore, since the folded dipole antenna 550 is used for wireless communication with other operating devices 100 and the inverted F-shaped antenna 560 is used for wireless communication with the terminal device 50, different wireless communications can be performed. Furthermore, since the folded dipole antenna 550 and the inverted F-shaped antenna 560 are disposed on the second surface 512 of the control substrate 500, the influence of the user's fingers on operating the touch panel 220 can be reduced.
