[First embodiment of beverage glass]
DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a drinking glass of the present invention will be described below with reference to the drawings.
As shown in FIG. 1(a), the beverage presentation glass 1 of the present embodiment is roughly constructed from a glass body 10, a fixing mechanism 15 for fixing a portable communication device 80, and a radio wave transmission tunnel 20.
The glass body 10 is a bottomed cylindrical body having an upper opening 11, and is a beverage container into which a beverage can be filled. Examples of the shape of the glass body 10 include the usual cup shape as shown in FIG. 1(a), as well as a beer mug with a handle. Note that the glass body 10 is curved in the horizontal direction like a normal cup or beer mug (that is, the shape of the glass body 10 is a cylindrical body like a normal cup or beer mug). As shown in the example in FIG. 1(b), a first radio wave transmitting surface 12 and a fourth radio wave transmitting surface 13 made of a dielectric material capable of transmitting radio waves are formed on the side surface of the glass body 10. The radio wave transmitting surface 12 and the fourth radio wave transmitting surface 13 are arranged to face each other. In the example of Fig. 1(a), the entire side surface of the glass body 10 is made of a dielectric material that transmits radio waves (that is, in Fig. 1(a), the entire side surface of the glass is made of a dielectric material, so that the first radio wave transmitting surface 12 and the fourth radio wave transmitting surface 13 are both made of dielectric material).
The fixing mechanism 15 attaches to the glass a portable communication device 80 that includes a video display section that displays images, a wireless communication section 85 that includes an antenna, an audio output section 86 (that is, a speaker) that outputs audio, and a control section that controls the driving of these components. This is a fixing mechanism for fixing to the side surface (or near the side surface) of the main body 10. In the example of FIG. 1(a), a pocket mechanism is used as the fixing mechanism 15 to fix the portable communication device 80 to the side surface of the glass body 10. As the fixing mechanism 15, a magnet mechanism, screws, etc. may be used in addition to the pocket mechanism. As in the example of FIG. 1(b), the portable communication device 80 is fixed near the fourth radio wave transmitting surface 13 (by the fixing mechanism 15), and the portable communication device 80 is fixed to the glass body 10 by the fixing mechanism 15. fixed on the outside.
The portable communication device 80 assumed in the beverage presentation glass 1 of the present invention includes a display (that is, a video display section 80), a wireless communication section 85, an audio output section 86, and a control section ( In other words, it is assumed to be a normal commercially available portable communication device or portable communication terminal device such as a smartphone (computer), a mobile phone, a smart phone, a PDA, a small notebook computer, etc.
The radio wave transmission tunnel 20 is a member that is fixed inside the glass body 10 to allow the radio waves that have entered the glass body 10 to penetrate to the outside of the glass body 10, and is made of a dielectric material that allows the radio waves to pass through. Become. As shown in the example of FIG. 1(b), a second radio wave transmitting surface 22 and a third radio wave transmitting surface 23 made of a dielectric material through which radio waves can pass are formed on the side surface of the radio wave transmitting tunnel 20. The second radio wave transmitting surface 22 and the third radio wave transmitting surface 23 are arranged to face each other. Note that the dashed arrows in FIGS. 1(a) and 1(b) represent an image of the path P of radio waves incident on the portable communication device 80 for the purpose of explanation. The first radio wave transmitting surface 12 and the second radio wave transmitting surface 22 are arranged in close contact with each other to the extent that radio waves (strictly speaking, radio waves from the portable communication device 80) can pass through them while the beverage L is present between them. Similarly, the third radio wave transmitting surface 23 and the fourth radio wave transmitting surface 13 are capable of passing radio waves (strictly speaking, radio waves of the portable communication device 80) with the beverage L existing between them. Because they are arranged in close contact with each other, even when the glass body 10 is filled with a beverage, the radio waves from the portable communication device 80 that have passed through the first radio wave transmitting surface 12 are transmitted to the second radio wave transmitting surface 22 and the third radio wave transmitting surface. 23 and then the fourth radio wave transmission surface 13 to reach the portable communication device 80 (more precisely, the wireless communication section 85 or antenna section built into the portable communication device 80). Since the radio wave transmission tunnel 20, including its interior, is entirely composed of a dielectric material (which allows radio waves to pass through), the radio wave transmission tunnel 20 minimizes the negative effects of the beverage L that shields radio waves, and allows the radio waves to pass through the glass body 10. P (more precisely, a radio wave penetration path P) can be created. In the example of FIG. 1(a), the radio wave transmission tunnel 20 is fixed (or supported) inside the glass body 10 by the U-shaped frame 29 and the support rod 28, but the radio wave transmission tunnel 20 inside the glass body 10 is As a fixing method, a magnet mechanism, a screw mechanism, a locking claw mechanism, etc. may be used.

A supplementary explanation of the radio wave transmission tunnel 20 will be provided using FIG. 1(b).
How close should the distance G1 between the first radio wave transmission surface 12 and the second radio wave transmission surface 22 and the distance G2 between the third radio wave transmission surface 23 and the fourth radio wave transmission surface 13 be ( Whether radio waves that can be received by the portable communication device 80 pass through depends on the frequency of the radio waves of the target portable communication device 80 and the type of beverage L filled in the glass body 10 (more precisely, the conductivity of the beverage). rate). It is known that the higher the electrical conductivity of an object and the higher the frequency of radio waves, the more severe the attenuation of radio waves that enter the object will be, based on Maxwell's electromagnetic equations and equations describing plane waves of radio waves. (Please refer to specialized books on the basics of radio engineering). In other words, the higher the conductivity of the beverage L and the higher the frequency of the radio waves, the shorter the skin depth δ [m] (for details, please refer to specialized books on the basics of electromagnetism and radio engineering. ). Therefore, when the radio waves are high frequency, distance G1 and distance G2 must be set shorter than when the radio waves are low frequency. Further, when the conductivity of the beverage L to be filled into the glass body 10 (that is, the target) is high, the distance G1 and the distance G2 must be set shorter than when the conductivity is low.
In principle, the distance G1 = 0 [m] (that is, the first radio wave transmitting surface 12 and the second radio wave transmitting surface 22 are brought into close contact) and the distance G2 = 0 [m] (that is, the third radio wave transmitting surface 23 and the fourth radio wave transmitting surface 22 are in close contact with each other). If the transparent surface 13 is brought into close contact with the glass body 10 (because there will be no beverage L in the radio wave path P that would block the radio waves), any radio wave of any frequency and any type of beverage will be transmitted to the glass body 10. However, if you unnecessarily set the distance G1 and the distance G2 to 0 [m], there is a disadvantage that the volume of the beverage L that can be filled into the glass body 10 will be reduced accordingly, so care must be taken.
When designing or manufacturing the beverage presentation glass 1 of the present invention, the frequency of the radio waves of the portable communication device 80, the type of beverage L (strictly speaking, the conductivity of the beverage L), Determine in advance the minimum strength of the amplitude of the radio waves (that is, the electric field strength) that you want the portable communication device 80 to receive, and the volume of the beverage L that you want to fill in the glass body 10, and then set the optimal distance according to these parameters. It is a good idea to find G1 and distance G2. Note that the specific method for calculating distance G1 and distance G2 is preferably calculated by electromagnetic field numerical analysis using a computer, such as the finite element method or FDTD method, or by actual measurement through experiments using actual beverages and radio waves.

In the drinking glass 1 of the present invention, there is a radio wave transmission tunnel 20 made of a dielectric material (through which radio waves pass) in the glass body 10, so that the radio waves from the mobile base station B are transmitted through the glass body 10 as shown in FIG. 2(a). and can penetrate the beverage L inside it.
On the other hand, if the radio wave transmission tunnel 20 does not exist inside the glass body 10, the radio waves from the mobile base station B are passed through toward the portable communication device 80 on the side of the glass body 10, as shown in FIG. 2(b). Since this is impossible (the radio waves are absorbed by the beverage L or reflected by the surface of the beverage L), the radio waves that can be received by the portable communication device 80 are radio waves reflected by other objects (such as walls) or glasses. Only radio waves that have been diffracted around (around) the main body 10 can be received. In other words, in the example of FIG. 2(b) (when the radio wave transparent tunnel 20 does not exist), the radio wave transmission distance between the mobile base station B and the mobile communication device 80 is the same as the example of FIG. 1(a) (when the radio wave transparent tunnel 20 does not exist). (if it exists). Therefore, in the beverage presentation glass 1 of the present invention that includes the radio wave transmission tunnel 20, the reception efficiency of the radio waves from the mobile base station B is better (compared to the case where the radio wave transmission tunnel 20 does not exist).
In addition, in the beverage presentation glass 1 of the present invention, the radio wave transmission tunnel 20, including its interior, must be entirely composed of a dielectric material (through which radio waves pass).

[Second embodiment of beverage glass]
Hereinafter, a second embodiment of the beverage presentation glass of the present invention will be shown using drawings, and parts having the same configuration as the beverage presentation glass 1 of the first embodiment will be designated by the same reference numerals. The explanation will be omitted.
As shown in FIGS. 3(a) and 3(b), the beverage presentation glass 1 of the present embodiment includes a radio wave transmission tunnel having an upper end face 24 made of a transparent material, and a radio wave transmission tunnel 20 (inside thereof). The third radio wave transmitting surface 23 is made of a transparent dielectric material, and the fourth radio wave transmitting surface 13 (that is, the side surface of the glass body 10 on the side where the portable communication device 80 is present) is made of a transparent dielectric material. is made of a transparent dielectric material, so the user U can display the image 82 of the portable communication device 80 (more specifically, the image 82 of the video display section 81) on the third radio wave transmitting surface 23, the fourth radio wave transmitting surface 13, and their upper end surfaces. It is possible to visually check the glass body 10 from the outside through 24. In the examples shown in FIGS. 3(a) and 3(b), the entire side surface of the glass body 10 is made of a transparent dielectric material, thereby making the area of the fourth radio wave transmitting surface 13 also a transparent dielectric material.
As shown in the projection optical path W of the image 82 in FIGS. 3(a) and 3(b), the image 82 of the portable communication device 80 (strictly speaking, the light of the image 82) 3. After passing through the radio wave transmission surface 23, it passes through the upper end surface 24 and reaches the upper opening 11.
Since the radio wave transmission tunnel 20 is made of a transparent dielectric material (more precisely, a colorless and transparent dielectric material), even if the beverage L is a beverage with low light transmittance (for example, dark tea or red wine), the user U1 will be able to It is possible to visually recognize an image 82 (more specifically, a reflected image 88 of the image 82) of the portable communication device 80 through the aperture 11 through the third radio wave transmitting surface 23, the fourth radio wave transmitting surface 13, and the upper end surface 24 thereof. (In other words, the radio wave transmission tunnel 20 prevents the beverage L with low light transmittance from entering the space around the projection optical path W of the light of the image 82.) By forcibly making the space around the projection optical path W of the image 82 transparent (strictly colorless and transparent) by the radio wave transmission tunnel 20, regardless of the color and transparency of the beverage L, the user U can view the image 82 from the upper opening 11. Light becomes visible. Furthermore, when the user U drinks the beverage L in the glass body 10, the water level of the beverage L decreases and the upper end surface 24 comes into contact with the air. The brightness of the image 82 of the portable communication device 80 seen through the third radio wave transmitting surface 23, the fourth radio wave transmitting surface 13, and the upper end surface 24 depends on the amount of L (that is, according to the water level in the glass body of the beverage L) The height is adjustable. Note that, as shown in FIG. 3(a), the upper end surface 24 is preferably flat in order to prevent scattering, diffused reflection, or distortion of the image 82. By making the upper end surface 24 flat, the user can comfortably view the image 82.

[Third embodiment of beverage glass]
Hereinafter, a third embodiment of the beverage presentation glass of the present invention will be shown using drawings, and parts having the same configuration as the beverage presentation glass 1 of the first embodiment will be designated by the same reference numerals. The explanation will be omitted.
As shown in FIG. 4(a), the beverage presentation glass 1 of this embodiment includes a chamber 25 (or an airtight air chamber) that can be filled with air inside the radio wave transmission tunnel 20.
The chamber 25 allows the radio wave transmission tunnel 20 to be made lighter. Furthermore, since air is an excellent dielectric material that allows radio waves to pass through easily (air passes radio waves more easily than glass or resin), a chamber 25 is provided in the radio wave transmission tunnel 20 (radio wave transmission tunnel 20) to form a hollow structure. By doing so, it is possible to dramatically increase the radio wave transmittance of the radio wave transmission tunnel 20. Note that the chamber 25 is desirably airtight so that air does not escape to the outside space.

In the beverage presentation glass 1 of this embodiment, as shown in FIG. 4(a), the chamber 25 is located at a position where it is exposed to sound waves generated from the audio output section 86 (i.e., speaker) built into the portable communication device 80. It is possible to amplify the sound waves of the audio output section 86 by resonance in the space inside the chamber 25.
In the beverage presentation glass 1 according to the present embodiment, as shown in FIG. 4(a), a third The distance G2 (strictly speaking, the shortest distance G2) between the third radio wave transmitting surface 23 and the fourth radio wave transmitting surface 13 is made shorter than 18 [mm] (the shortest sound wave wavelength among the sound wave wavelengths in the audible range). Also good.
According to the basic laws of physics (strictly speaking, the principle of least action) or the basic properties of sound waves, the energy of the sound waves radiated from the sound wave source (i.e., the audio output section 86 or the speaker) becomes a sound wave as shown in Figure 4(b). The further away you are from the source, the weaker it becomes as it spreads out radially. For example, the sound wave energy of the audio output unit 86 that can be received at a position one wavelength (λ[m]) away from the audio output unit 86 can be received at a position five wavelengths (5λ[m]) away from the audio output unit 86. It is low compared to the energy.
Furthermore, the frequency range of sound that the human ear can hear is said to be from 20[Hz] to 20,000[Hz] (this is called the audible range), and the speed of sound in the air is approximately 340[Hz]. m/s] to approximately 360[m/s], the wavelength of sound traveling through the air at 20,000[Hz] (that is, the highest frequency in the audible range) is approximately 17[mm] to 18[mm] ( For details, please refer to specialized books on acoustic engineering). Therefore, in order to efficiently transmit the sound waves or sound energy from the audio output section 86 (speaker) of the portable communication device 80 to the space inside the chamber 25 of the radio wave transmission tunnel 20, it is necessary to use the third radio wave transmission surface 23 and the fourth radio wave transmission surface. 13 is preferably at least 18 [mm] or less. In other words, the distance G2 is preferably one wavelength (18 [mm]) of the highest frequency in the human audible range (20,000 [Hz]) or less.
By setting the distance G2 to 18 [mm] or less (that is, one wavelength λ [m] or less), the sound waves in the highest frequency part of the audible range (20,000 [Hz]) will not be spread (unnecessarily into the surrounding space). It is possible to efficiently transmit the information to the space inside the chamber 25. In other words, by setting the distance G2 to 18 [mm] or less, it becomes possible to increase the volume or sound energy in the band around 20,000 [Hz] that resonates in the space of the chamber 25.
Furthermore, the length of one wavelength of a sound wave in the low frequency part of the audible range (for example, 20 [Hz]) is approximately 18 [m], which is extremely large (compared to the wavelength of 18 [mm] in the high frequency part of the audible range). becomes the value. Therefore, as long as the distance G2 satisfies the condition that it is one wavelength (18 [mm]) or less of the highest frequency (20,000 [Hz]) in the audible range, the distance G2 will automatically be set to the lowest frequency (20,000 [Hz]) in the audible range. This also satisfies the condition of one wavelength (18 [m]) of [Hz]) (this is based on the basic principle of sound waves that the lower the frequency of a sound wave, the longer the wavelength of the sound wave). In other words, if the distance G2 is shorter than 18 [mm], the sound waves of the audio output section 86 will be efficiently transmitted to the space (resonance space) inside the chamber 25 over the entire audible range (20 [Hz] to 20,000 [Hz]). can. In addition, in the beverage presentation glass 1 of this embodiment, the beverage L that exists between the third radio wave transmitting surface 23 and the fourth radio wave transmitting surface 13 (that is, within the distance G2) functions as a sound wave transmission medium. (Although the acoustic impedance of water and beverages is larger than that of air, if the distance G2 is set to a very short value of 18 [mm], the sound waves will reach the space inside the chamber 25 without any problems.)
In the beverage presentation glass 1 of this embodiment, a method has been described in which the radio wave transmission tunnel 20 can also be used as a highly efficient sound resonance amplifier. By using the beverage presentation glass 1 of this embodiment, the user can make loud sounds or call voices without increasing the sound volume (or electrically amplifying) the audio output unit 86 (speaker) of the portable communication device 80. You can enjoy it. Furthermore, since the sound speed of water and air is approximately 4 to 5 times different, when filling a beverage, even if the distance G2 is 1.8 [mm] x 4 to 5 times, in principle, the sound waves will reach chamber 25, but the user will not be able to drink the beverage. In this case, it is assumed that the glass is not always full of drinks and may be about half full, so the distance G2 is preferably within 1.8 [mm].

[Fourth embodiment of beverage glass]
Hereinafter, a fourth embodiment of a drinking glass according to the present invention will be described with reference to drawings, and parts having the same configuration as the drinking glass 1 of the third embodiment will be designated by the same reference numerals. The explanation will be omitted.
As shown in FIG. 5, the beverage presentation glass 1 of this embodiment includes a beam splitter 30 that is detachable in the space of the chamber 25 (inside the radio wave transmission tunnel 20). It is provided with an insertion port 31 (in the radio wave transmission tunnel 20) for insertion (or attachment/detachment or mounting), the first radio wave transmission surface 12 is made of a transparent dielectric, and the second radio wave transmission surface 22 is made of a transparent dielectric. , the third radio wave transmitting surface 23 is made of a transparent dielectric, the fourth radio wave transmitting surface 13 is made of a transparent dielectric, the radio wave transmitting tunnel is entirely made of the transparent dielectric 20, and the image 82 of the portable communication device 80 is passes through the fourth radio wave transmitting surface 13, the third radio wave transmitting surface 23, the second radio wave transmitting surface 22, and the first radio wave transmitting surface (in order), and is reflected by the beam splitter 30 of the portable communication device 80 (more precisely The feature is that the image 82 of the video display section 81) passes through the upper surface or upper part of the radio wave transmission tunnel 20 and reaches the upper opening 11 (that is, the outside of the glass body 10). (Note that the beam splitter 30 is fixed in the chamber 25 at an angle with respect to the bottom surface of the glass body 10, as shown in FIG. 5, in order to reflect the light of the image 82 toward the upper opening 11.)
In the beverage presentation glass 1 of this embodiment, the beam splitter 30 is housed inside the transparent radio wave transmission tunnel 20 as shown in FIG. (for example, dark colored tea or red wine), the user U1 can visually recognize the image 82 (more specifically, the reflected image 88 of the image 82) of the portable communication device 80 through the upper opening 11 (that is, the radio wave transmission The tunnel 20 prevents the beverage L with low light transmittance from entering the space around the beam splitter 30). By forcibly making the space around the beam splitter 30 transparent (strictly, colorless and transparent) using the radio wave transmission tunnel 20, regardless of the color and transparency of the beverage L, the light projection optical path W1 of the image 82 and the light projection optical path Most or all of W2 is forcibly made transparent (in the example of FIG. The transmitted projection optical path is referred to as projection optical path W2).
In the beverage presentation glass 1 of this embodiment, the beam splitter 30 is inserted (installed) into the transparent (strictly colorless and transparent) radio wave transmission tunnel 20 (inside the chamber 25) through the insertion opening 31. The whole can be used as a giant beam splitter. Note that if you do not want to use the radio wave transmission tunnel 20 as a beam splitter, the beam splitter 30 can be taken out of the radio wave transmission tunnel 20 through the insertion port 31.
A major advantage of the beverage presentation glass 1 of this embodiment is that the beam splitter of the radio wave transmission tunnel 20 can be turned on and off depending on the transparency of the beverage L and the situation.
There is one point to note regarding the reflected image 88 reflected by the beam splitter. As shown in FIG. 5, the beam splitter 30 placed inside the radio wave transmission tunnel 20 directs a portion of the light of the image 82 of the portable communication device 80 (50% if the beam splitter 30 is a half mirror) to the second radio wave transmission surface. 22 (or the first radio wave transmission surface 12) direction, the light of the image 82 (that is, the light of the reflected image 88) that necessarily passes through the upper part or top surface of the radio wave transmission tunnel 20 is attenuated by the loss due to the transmission. Caution must be taken. Therefore, the reflected image 88 reflected by the beam splitter 30 is darker than the image 82 when viewed directly through the third radio wave transmitting surface 23 and the fourth radio wave transmitting surface 13 without passing through the beam splitter 30. Therefore, if you want to view the bright light image 82 through the radio wave transmission tunnel 20 from the upper aperture 11, it is better to view it directly through the third radio wave transmission surface 23 and the fourth radio wave transmission surface 13 without going through the beam splitter 30 ( This makes the image 82 appear brighter to the user than when viewed through the beam splitter 30).
Note that, as a method for fixing the beam splitter 30 in the chamber 25, it is preferable to use a removable mechanism or method such as a magnet mechanism, a locking claw mechanism, or a screw. Further, the insertion port 31 may be provided anywhere in the radio wave transmission tunnel 20.

As shown in FIGS. 6(a) and 6(b), a lower opening 26 for connecting the space inside and outside the chamber 25 may be provided near the lower end (or lower area) of the radio wave transmission tunnel 20. This is a device to prevent the beverage L from flowing into the space inside the chamber 25 when the glass body 10 is tilted (the air inside the chamber 25 is always raised due to the water pressure of the beverage L inside the glass body 10). Therefore, even if the lower opening 26 is provided near the lower end of the radio wave transmission tunnel 20, the beverage L will hardly flow into the space inside the chamber 25 from the lower opening 26).
The lower opening 26 also functions as an insertion port 31 for taking the beam splitter 30 into and out of the chamber 25.
A lid 27 for closing the lower opening 26 may be provided as shown in FIG. 6(b). The water pressure that the lid 27 attached to the lower opening 26 receives is applied in the direction of the upper opening 11 of the glass body 10, so the lid 27 can strongly prevent the beverage L from flowing into the space inside the chamber 25 (reinforces the airtightness of the chamber 25). ).
Although not directly related to the present invention, in Japan, a space or room filled with air is sometimes pronounced as "chamber" instead of "chamber", but in the present specification, the notation is unified as "chamber".

[Fifth embodiment of beverage glass]
Hereinafter, a fifth embodiment of the beverage presentation glass of the present invention will be shown using drawings, and parts having the same configuration as the beverage presentation glass 1 of the first embodiment described above will have the same reference numerals. , and the explanation thereof will be omitted.
As shown in FIG. 7(a), in the drinking glass 1 of this embodiment, the radio wave transmission tunnel 20 is entirely made of a transparent dielectric, the first radio wave transmission surface 12 is made of a transparent dielectric, and the second radio wave transmission tunnel 20 is made of a transparent dielectric. The radio wave transmission surface 22 is made of a transparent dielectric, the third radio wave transmission surface 23 is made of a transparent dielectric, the fourth radio wave transmission surface 13 is made of a transparent dielectric, and the second radio wave transmission surface 22 is flat. , the first radio wave transmitting surface 12 is curved in a convex shape toward the outside of the glass body 10, and the light of the image 82 of the portable communication device 80 (strictly speaking, the video display section 81) passes through the fourth radio wave transmitting surface 13. , the third wave transmitting surface 23, the second radio wave transmitting surface 22, and the first radio wave transmitting surface 12 in this order, and an image 82 of the portable communication device 80 (strictly speaking, the video display section 81) is transmitted when the drink is filled into the glass body 10. is characterized in that the image 82 of the portable communication device 80 (image display unit 81) is enlarged by transmitting the beverage between the second radio wave transmitting surface 22 and the first radio wave transmitting surface.
As shown in FIG. 7(b), since the beverage L (or beverage L2) between the second radio wave transmitting surface 22 and the first radio wave transmitting surface 12 has the same shape as a plano-convex lens, the image of the portable communication device 80 is 82 passes through the area of the beverage that has the shape of a plano-convex lens (that is, the area of the beverage L2 between the second radio wave transmitting surface 22 and the first radio wave transmitting surface 12), thereby creating the transmitted image 87 in FIG. 7(a). The image is enlarged in the horizontal direction compared to the image 82. Since the refractive index of water light is approximately 1.33, which is higher than that of air, the area of the beverage L2, which is shaped like a plano-convex lens, magnifies the image 82 as an optical lens (beverage lens).
In the beverage presentation glass 1 of the present embodiment, the beverage L (or beverage L2) between the second radio wave transmitting surface 22 and the first radio wave transmitting surface 12 is made of a plano-convex lens; As shown in (b), the area of the beverage lens L2 (in the shape of a plano-convex lens) formed by the beverage L can be placed in front of the radio wave transmission tunnel 20 when viewed from the user U (in other words, it can be placed in front of the user U's eyes). ), it is possible to enhance the power and realism of the transparent image 87 (enlarged image of the image 82) seen from the user U.

[First embodiment of radio wave transmission device]
Hereinafter, a first embodiment of a radio wave transmitting device of the present invention will be shown using drawings, and parts having the same configuration as the drinking glass 1 of the first embodiment will be denoted by the same reference numerals. The explanation will be omitted.
As shown in FIG. 8(a), the radio wave transmission device 100 of this embodiment includes a radio wave transmission tunnel 20, a support rod 28 for fixing (or supporting) the radio wave transmission tunnel 20 inside the glass body 10, A U-shaped frame 29 is provided.
The upper end of the support rod 28 is connected to the U-shaped frame 29, and the lower end of the support rod 28 is connected to the radio wave transmission tunnel 20, with an upper opening as shown in FIGS. 8(a) and 8(b). The radio wave transmission tunnel 20 is fixed within the glass body 10 by inserting the end portion of the glass member 11 into the U-shaped frame 29.
With the end of the upper opening 11 inserted into the U-shaped frame 29, the radio waves from the portable communication device 80 that passed through the first radio wave transmission surface 12 passed through the second radio wave transmission surface 22 and the third radio wave transmission surface 23. It is characterized in that it later passes through the fourth radio wave transmission surface 13 and reaches the portable communication device 80.
Since the radio wave transmission device 100 includes the support rod 28, the user can place the radio wave transmission tunnel 20 inside the glass body 10 without touching the beverage L inside the glass body 10.
In the example of FIG. 8(a), the U-shaped frame 29 and the support rod 28 are plate-shaped. By forming the glass body 10 into a plate shape, the contact area that contributes to friction between the glass body 10 and the support rod 28 or U-shaped frame 29 increases compared to when the support rod 28 is rod-shaped. The fixing strength increases accordingly.

The present invention is a drinking glass that is equipped with a radio wave transmission tunnel inside, and allows radio waves from a portable communication device to be transmitted and received by penetrating the glass body and the beverage within the glass body through the radio wave transmission tunnel. It is a production glass. Further, by using the radio wave transmission device of the present invention, the user can place the radio wave transmission tunnel inside the glass body without touching the beverage inside the glass body. As described above, the present invention has industrial applicability.
