Further, as shown in FIG. 2, a rectangular opening 111 is formed on the front surface of the main body of the electronic device 1 (hereinafter referred to as “front surface”) so that the longitudinal direction coincides with the width direction of the electronic device 1. It is formed. In the electronic device 1, the fluorescent display tube 120 is provided inside the housing 11 so that the display surface 14 on which various information is displayed is positioned in the opening 111 of the housing 11. Here, the display surface 14 has the same size and the same shape as the opening 111. The information displayed on the display surface 14 by the fluorescent display tube 120 is the performance time of the content being played back by the electronic device 1 and the name of the content. In addition to this, a plurality of operation buttons 12 and a tray 13 that stores a recording medium and can be opened and closed are provided on the front surface of the housing 11.

  FIG. 3 is a block diagram illustrating a hardware configuration of the electronic device 1. As shown in FIG. 3, the configuration of the electronic device 1 is roughly divided into an electronic component group 110, a fluorescent display tube 120, and an antenna 130. The electronic component group 110 is provided in the electronic device 1 so as to be covered by the housing 11 and is controlled according to the operation of the operation button 12 or control for reading out and reproducing the content from the recording medium stored in the tray 13. And an electronic circuit for controlling the operation of the electronic apparatus 1. The electronic component group 110 includes an electronic circuit as a wireless communication module for performing wireless communication realized by transmission / reception of radio waves using the antenna 130. As described above, the electronic component group 110 includes various electronic components necessary for the electronic device 1 to function as an audio video player.

  The fluorescent display tube 120 is an example of the display device according to the present invention, and displays information by light transmitted through the display surface 14 (ie, visible light) under the control of the electronic component group 110. The configuration of the fluorescent display tube 120 will be described later. The visible light of this embodiment has a component in a frequency band of 380 nm to 780 nm, for example, but is a light having a wavelength used for the purpose of displaying information (image), and is used for the purpose of making it visible to humans. Any light can be used.

The antenna 130 includes a printed wiring board on which an antenna element pattern is formed, and is used to realize wireless communication under the control of the wireless communication module of the electronic component group 110. The electronic device 1 includes two antennas, antennas 130a and 130b (see FIGS. 4 and 5). The antenna 130a is an example of the first antenna of the present invention, and the antenna 130b is an example of the second antenna of the present invention. In the case where it is not necessary to distinguish the antennas 130a and 130b from each other, they are collectively referred to as “antenna 130” below.
As described above, in the electronic device 1, a wireless communication device is configured by the wireless communication module of the electronic component group 110 and the antenna 130.
Next, the configuration of the fluorescent display tube 120 and the antenna 130 will be described more specifically.

FIG. 4 is a front view of the electronic device 1. FIG. 4 illustrates a state in which the periphery of the display surface 14 of the electronic device 1 is viewed from the front. FIG. 5 is a cross-sectional view of the fluorescent display tube 120 when the electronic apparatus 1 is cut at a certain height position (a cross-sectional view taken along the line VV in FIG. 4).
The fluorescent display tube 120 includes an envelope 121, a filament cathode 122, a grid electrode 123, a plurality of anodes 124, and a pair of support members 125.
The envelope 121 holds a high-vacuum atmosphere in the internal space, and is a display panel 1211 that is a first substrate, a second substrate on which the anode 124 is disposed, and is disposed to face the display panel 1211. A rear substrate 1212 and a side plate 1213 which is a pair of third substrates bonded to the display panel 1211 and the rear substrate 1212 are provided. Here, each of the display panel 1211, the back substrate 1212, and the side plate 1213 is, for example, transparent or translucent, and transmits visible light. For example, each of the display panel 1211, the back substrate 1212, and the side plate 1213 is formed in a flat plate shape using a resin material such as plastic or a light-transmitting material such as glass. Further, the display panel 1211, the back substrate 1212, and the side plate 1213 each transmit radio waves transmitted and received by the antenna 130. That is, the entire envelope 121 transmits visible light and radio waves.

The surface of the display panel 1211 facing the outside of the housing 11 is the display surface 14. On the other hand, a mounting portion 1211 a is provided on the surface of the display panel 1211 opposite to the display surface 14. The mounting portion 1211a has a pair of configurations formed so as to form a concave shape. The antenna 130a is fitted into one mounting portion 1211a, and the antenna 130b is fitted into the other mounting portion 1211a.
Note that for mounting the antenna 130 on the mounting portion 1211a, a fixing member such as a metal fitting may be used separately, and a well-known method for fixing the antenna 130 may be employed. Further, the mounting portion 1211a may be integrally formed with the display panel 1211.

  The filament cathode 122 is provided inside the envelope 121 and extends in the width direction of the electronic apparatus 1 in parallel with the display surface 14. A plurality of filament cathodes 122 are arranged so as to be orthogonal to the extending direction, and intervals between adjacent ones are substantially the same. The filament cathode 122 is formed, for example, by depositing, for example, an alkaline earth metal carbonate as an electron emitting material on the surface of a core wire such as tungsten having a diameter of several μm to several tens μm. A voltage is applied to each end of the filament cathode 122 via a cathode (not shown) under the control of the electronic component group 110, and the temperature rises according to the applied voltage to emit thermoelectrons.

  The grid electrode 123 is provided inside the envelope 121, and both ends thereof are supported by the support member 125. The grid electrode 123 is sandwiched between the filament cathode 122 and the anode 124 and is configured in a planar shape so as to be separated from them. The grid electrode 123 is formed in a mesh shape in a planar shape, and is provided so as to cover the entire anode 124. A voltage is applied to the grid electrode 123 via an electrode (not shown) at the position of the support member 125, and the grid electrode 123 becomes an anode according to the applied voltage. When a positive voltage is applied, the grid electrode 123 accelerates the thermal electrons emitted from the filament cathode 122 and causes the electrons to collide with the anode 124. Conversely, when a negative voltage is applied, the grid electrode 123 blocks electrons that are also directed to the anode 124.

  The anode 124 is an example of the display element of the present invention, and includes an anode conductor and a phosphor layer laminated on the anode conductor, and a plurality of anodes 124 are provided on the back substrate 1212 so as to form a display pattern. In the anode 124, when the electrons accelerated by the grid electrode 123 collide with the phosphor layer, the phosphor layer is excited to change into photoelectrons to emit light. The anode 124 is driven under the control of the electronic component group 110 and displays information by light transmitted through the display panel 1211. The back substrate 1212 provided with the anode 124 is electrically connected to a wiring pattern for electrically connecting the lead and the anode 124 (not shown) or the lead and the grid electrode 123 in order to drive the anode 124. A wiring pattern for electrically operating the electronic device 1 (here, the fluorescent display tube 120) such as a wiring pattern is formed on the rear substrate 1212. Such a lead is a lead electrode for supplying a necessary voltage or electric signal to the electrode inside the fluorescent display tube 120. On the other hand, the display panel 1211 and the side plate 1213 which are substrates other than the back substrate 1212 of the envelope 121 are not provided with a wiring pattern for electrically operating the electronic device 1.

  By the way, as shown in FIG. 4, the display surface 14 includes a display area 141 and a non-display area 142. The display area 141 is a part of the display surface 14 and is a rectangular area indicated by a two-dot chain line in FIG. The display area 141 is an area used for displaying information according to driving of the anode 124. In the display area 141, a smoke film is secured so as to ensure a light transmitting property that allows visible light emitted from the anode 124 to pass therethrough, and the electronic device can be displayed without obstructing the display of information on the display surface 14. 1 It is difficult to see the equipment inside. The non-display area 142 is an area excluding the display area 141 in the display surface 14. The non-display area 142 is an area that has a lower ratio of transmitting visible light than the display area 141 and is not used for displaying information according to the driving of the anode 124.

Here, the display area 141 overlaps the area where the anode 124 is disposed with respect to the normal direction of the display surface 14. The non-display area 142 is an area surrounding the display area 141 and does not overlap the area where the anode 124 is disposed in the normal direction of the display surface 14. The non-display area 142 is printed using, for example, a black colorant, and hardly transmits light. The non-display area 142 is subjected to such printing in order to prevent, for example, the electronic component group 110 provided in the electronic device 1 and the components of the fluorescent display tube 120 from being visually observed. A character or the like for explaining information displayed on the display surface 14 may be printed.
Next, the antenna 130 provided on the fluorescent display tube 120 will be described.

  The antenna 130 is mounted and fixed to the mounting portion 1211a, and is electrically connected to the wireless communication module of the electronic component group 110 through a coaxial line having a characteristic impedance of 50Ω. For this connection, as in the conventional method, a coaxial connector having a characteristic impedance of 50Ω that is electrically connected to the electronic component group 110 is provided in the fluorescent display tube 120, and the antenna 130 and this connector are connected by electrical wiring. . The reason why the two antennas 130a and 130b are provided in the electronic device 1 is to realize so-called diversity in the electronic device 1. That is, for the same signal received by each of the antennas 130a and 130b, communication is performed by preferentially using an antenna signal with excellent radio wave conditions or by synthesizing the received signal to remove noise. In order to improve the quality and reliability of the electronic apparatus 1, the electronic apparatus 1 is configured as described above. As can be seen from FIG. 5, the antennas 130 a and 130 b are provided so as to face each other across the region where the anode 124 is disposed in the width direction of the electronic device 1.

  The antenna 130 is provided in the fluorescent display tube 120 so as not to block visible light from the plurality of anodes 124 toward the display panel 1211. In this embodiment, the antenna 130 is provided on the surface inside the housing 11 of the display panel 1211 of the fluorescent display tube 120. In order to realize such an arrangement of the antenna 130, the mounting portion 1211 a is not on the visible light optical path from the plurality of anodes 124 toward the display panel 1211, on the surface inside the housing 11 of the display panel 1211. Provided.

The antenna 130 is mounted such that the surface on which the antenna element pattern is formed (hereinafter referred to as “pattern forming surface”) faces the internal space of the envelope 121. As a result, radio waves can propagate through the opening 111 between the pattern forming surface of the antenna 130 and the outside of the housing 11. Further, the antenna 130 is mounted so that substantially the whole thereof overlaps the non-display area 142 with respect to the normal direction of the display surface 14. Thereby, even if the antenna 130 is provided at the position shown in FIG. 5, the antenna 130 is not visually recognized from the outside due to the presence of the non-display area 142. Furthermore, since the position where the antenna 130 is provided overlaps the area where the non-display area 142 and the support member 125 are provided in the normal direction of the display surface 14, the electronic device is compared with the conventional fluorescent display tube. It is not necessary to increase the size of the fluorescent display tube 120 in the width direction of 1. In short, in the display panel 1211 which is a substrate on which the wiring pattern is not provided in the fluorescent display tube 120, the region opposite to the non-display region 142 exists as an empty space in the conventional fluorescent display tube. In 120, the antenna 130 is provided using this area.
Although it is preferable that the entire antenna 130 overlaps the non-display area 142 with respect to the normal direction of the display surface 14, a part of the antenna 130 may overlap the housing 11 or the like.

In addition, the antenna 130 is a substrate that is not the back substrate 1212 of the fluorescent display tube 120 and is not provided with the wiring pattern, so that the antenna 130 is electrically generated from the wiring pattern. It is possible to suppress noise and the like from interfering with radio waves used for wireless communication transmitted and received by the antenna 130. In particular, the display panel 1211 is a substrate that is provided at a relatively large distance from the back substrate 1212 on which the wiring pattern is formed and that is provided at a position relatively close to the opening 111. This is a reason why the antenna 130 is preferable as compared with other substrates. With the above configuration, according to the electronic device 1, the radio wave transmitted / received by the antenna 130 causes a problem in the display of the fluorescent display tube 120, or the electrical system that is received by the fluorescent display tube 120 is used for transmitting / receiving radio waves in the antenna 130. The inconvenience of giving can be more reliably suppressed.
In the fluorescent display tube 120, if the space in which the antenna 130 is provided and the space in which the anode 124 is provided are separated so that propagation of radio waves between these spaces is suppressed, such inconvenience is further suppressed. It is done.

  By mounting the antenna 130 on the fluorescent display tube 120 with the above configuration, a radio wave propagation path including the opening 111 (display panel 1211) is formed between the antenna 130 and the outside of the housing 11. Therefore, the electronic device 1 can perform wireless communication with the outside using the antenna 130 without being obstructed by the metal casing 11. Specifically, since the envelope 121 (particularly, the display panel 1211) is made of a material that transmits radio waves, even if the opening 111 is blocked by the display panel 1211, the display panel 1211 does not transmit radio waves. Does not interfere with propagation. As described above, in the configuration of the electronic device 1, even if the housing 11 is formed of a material such as a metal that blocks radio waves, the effect of the housing 11 on the transmission / reception sensitivity of the antenna 130 is almost ignored. Can do.

  As described above, in an electronic device having a display device inside a casing that blocks radio waves such as metal, an opening for providing a display panel is conventionally formed in the casing. In the electronic device 1, the antenna 130 is provided in the vicinity of the opening 111 (display surface 14) so that radio waves can be transmitted and received through the opening 111. As a result, the antenna 130 can be installed so that wireless communication is not hindered by the housing 11 while suppressing deformation such as applying special processing to the structure of the electronic device having the conventional configuration. The manufacturing process of the electronic device equipped with the device is not complicated. In addition, since the antenna 130 is provided so as to almost entirely overlap the non-display area 142 with respect to the normal direction of the display surface 14, the antenna 130 provided on the fluorescent display tube 120 is externally connected via the display panel 1211. Is not visible. Further, a support member that supports components such as the grid electrode of the fluorescent display tube is generally provided near both ends of the grid electrode. Therefore, the mounting portion 1211 a is provided at a position overlapping the support member 125 with respect to the normal direction of the display surface 14, so that the size of the fluorescent display tube 120 is increased without increasing the size of the electronic device 1 in the width direction. An antenna 130 can be provided in the device 1.

[Modification]
The present invention can be implemented in a form different from the above-described embodiment. Further, the following modifications may be combined as appropriate.
(Modification 1)
In the embodiment described above, the antenna 130 is provided on the display panel 1211 of the fluorescent display tube 120. However, the antenna 130 may be provided at a position other than this on the fluorescent display tube 120. In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.
6 and 7 are cross-sectional views of the fluorescent display tube 120 of this modification when the electronic apparatus 1 is cut at a certain height position (cross-sectional view taken along the line VV in FIG. 4).
First, as shown in FIG. 6, the antenna 130 may be provided on the back substrate 1212 on which the anode 124 is provided. For example, a pair of mounting portions 1212a for mounting the antenna 130 by securing a space further outside the support member 125 in the width direction of the electronic device 1 and the direction in which the pair of support members 125 are arranged. Is provided. Also in this case, as in the above-described embodiment, the antenna 130 is mounted on the mounting portion 1212a so that the radio wave pattern forming surface faces the inner space of the envelope 121.
In the case of this configuration, it is preferable to enlarge the non-display area 142 when the display area 141 having the same dimensions as the above-described embodiment is secured. In the configuration in which the antenna 130 is provided inside the envelope 121, the mounting portion having the above-described configuration may be provided on the rear substrate 1212, and the antenna 130 may be mounted on this mounting portion.

  Further, as shown in FIG. 7, the rear substrate 1212 provided with the anode 124 may be enlarged in the width direction of the electronic apparatus 1, and the antenna 130 may be provided outside as viewed from the envelope 121. In this case, a pair of mounting portions 1212 b for mounting the antenna 130 is provided on the outer surface of the envelope 121. Also in this case, the antenna 130 is mounted on the mounting portion 1212b so that the pattern forming surface faces the side opposite to the mounting portion 1212b, as in the embodiment described above. In this configuration, the antenna 130 is provided so as to overlap the front surface of the housing 11 with respect to the normal direction of the display surface 14 and not to overlap the display surface 14. Therefore, the antenna 130 is more difficult to see from the outside of the electronic device. Further, since the entire envelope 121 is made of a material that transmits radio waves, wireless communication using the antenna 130 is not hindered even with the configuration shown in FIG.

  In addition, the mounting portion of the present invention is not limited to the above position as long as the mounted antenna is provided so as not to block visible light from the display element toward the display panel. The antenna 130 transmits and receives radio waves that are electromagnetic waves in a higher frequency band than, for example, ultrasonic waves and infrared light. Therefore, the pattern forming surface of the antenna 130 (that is, the surface used for transmitting and receiving radio waves) does not have to be directed to the opening 111 inside the housing 11. For example, the arrangement may be such that the opening 111 is not positioned in the normal direction of the pattern forming surface of the antenna 130. Further, even if a member that blocks electromagnetic waves (for example, visible light, infrared light, or ultrasonic waves) is provided between the pattern formation surface of the antenna 130 and the opening 111, the pattern formation of the opening 111 and the antenna 130 is performed. If a medium that transmits radio waves is continuous with the surface, the antenna 130 can transmit and receive radio waves that pass through the display panel 1211 located in the opening 111.

(Modification 2)
In the embodiment described above, the entire envelope 121 is formed of a material that transmits radio waves. However, a portion that does not become a propagation path of radio waves transmitted and received by the antenna 130 is a material that does not transmit radio waves, that is, conductive. It may be formed of a material having In addition, in the fluorescent display tube 120, it is possible to display information according to driving of the anode 124 as long as the display panel 1211 constituting the display surface 14 transmits at least light. Therefore, the portion of the envelope 121 that does not hinder the display of information may be formed of a material that does not transmit visible light.
In the electronic device 1 of the above-described embodiment, the display surface 14 is configured by the display area 141 and the non-display area 142, but the display surface 14 may be configured by only the display area 141.

(Modification 3)
The electronic apparatus of the present invention is not limited to the audio video player as in the above-described embodiment. Examples of the electronic apparatus of the present invention include a video content recorder / player, an AV (Audio Visual) amplifier, a television, a car navigation device, a mobile phone, and a device equipped with a touch panel. In short, the present invention can be applied to an electronic device in which at least the front portion of the main body is formed of a member that blocks radio waves and has a display device inside a housing in which an opening is formed.

The display device of the present invention is not limited to a so-called fluorescent display tube. The display device of the present invention may be a display device such as a liquid crystal display device, a plasma display panel, or a field emission display. In this case, the display element of the present invention corresponds to, for example, a pixel. In this case, the pixel may include a liquid crystal element that changes a ratio of passing visible light irradiated by the backlight, or a pixel that includes an organic EL (Electro Luminescence) element that emits light. In short, as long as the display element of the present invention displays information by visible light transmitted through the display panel, the driving method and the presence or absence of light emission of the element itself are not particularly questioned. Even in such a display device, it is considered that the antenna 130 is preferably provided on the display panel rather than other substrates for the same reason as in the above-described embodiment.
Further, the display panel of the present invention may be configured, for example, as a lid that can be opened and closed with respect to the electronic device 1, realizes a function as a display panel of the display device, and is an opening of a housing of the electronic device What is necessary is just to be located in.

  The antenna of the present invention is not limited to one that performs wireless communication using a wireless LAN, but may be an antenna for realizing wireless communication such as another short-range wireless communication method. The antenna of the present invention may perform only one of transmission and reception of radio waves. In short, the antenna of the present invention is not limited to a specific one in terms of its structure and wireless communication system.
