[0013] 1 to 4 is a base for supporting a display. The display is, for example, a transparent display. As shown in FIG. 1 to FIG. 4, the display base 11 has a mounting portion 12, legs 13, a storage portion 14, and a tray portion 15. The materials of each portion of the display base 11 are made of a material that can provide a weight to lower the position of the center of gravity of the entire display when the transparent display is placed on the mounting portion 12. For example, the mounting portion 12, legs 13, storage portion 14, and tray portion 15 are made of a metal material (e.g., iron). By lowering the position of the center of gravity, the transparent display placed on the display base 11 is less likely to tip over. The position of the center of gravity may be at a height within a range of, for example, 150 mm to 300 mm from the contact surface between the bottom surface of the display base 11 (the bottom surface of the tray portion 15) and the installation location. The design value for the weight of the legs 13 is, for example, 0.8 kg, and the settable value range is, for example, 0.5 kg to 1.5 kg. The design value for the weight of the storage section 14 is, for example, 0.2 kg, and the settable value range is, for example, 0.1 to 1.0 kg. The design value for the weight of the tray section 15 is, for example, 2.0 kg, and the settable value range is, for example, 1.0 to 5.0 kg. The design value for the total weight of the legs 13, storage section 14, and tray section 15 is, for example, 3.0 kg, and the settable value range is, for example, 1.6 kg to 11.0 kg.

[0014] (1) Placement section 12 The placement unit 12 can place one side of the transparent display along the horizontal direction of the main surface thereof, and supports the placed transparent display. Therefore, the length of the longitudinal direction of the placement unit 12 is set to a length corresponding to one side of the main surface of the transparent display along the horizontal direction. The longitudinal direction of the placement unit 12 is the longitudinal direction of the placement surface AR1 when the display base 11 is viewed from the front as shown in FIG. 2, for example. The length of the depth direction of the placement unit 12 is set to a length corresponding to one side of the transparent display along the thickness direction. The depth direction of the placement unit 12 is the depth direction of the display base 11 when the display base 11 is viewed from the front as shown in FIG. 2, for example. The transparent display may be placed on the placement unit 12 so as to be placed horizontally or vertically.

[0015] An opening is provided at the top of the mounting portion 12, through which a transparent display can be inserted. The transparent display is placed on the mounting portion 12 by inserting the lower part of the transparent display into the opening. The lower part of the transparent display is, for example, a part including a portion of the transparent display excluding the display part (hereinafter also referred to as a "control part"). The transparent display placed on the mounting portion 12 is fixed to the mounting portion 12 by any method. For example, it is fixed to the mounting portion 12 by a screw 16. The transparent display may be fixed to the mounting portion 12 together with the legs 13 by the same screw 16, or may be fixed to the mounting portion 12 by a different screw 16 separate from the legs 13.

[0016] In addition, in the placement unit 12, the placement surface AR1 may be provided with a design according to the user who will be the owner of the display base 11. For example, the name, logo, etc. of the company that is the owner can be printed on the placement surface AR1.

[0017] (2) Legs 13 The legs 13 are provided at a first end, which is one end in the longitudinal direction of the mounting portion 12, and a second end, which is the end opposite to the first end, to support the mounting portion 12. In the display base 11 shown in Figs. 1 to 4, as an example, a leg 13-1 is provided at the first end of the mounting portion 12, and a leg 13-2 is provided at the second end of the mounting portion 12. The legs 13 are fixed to the mounting portion 12 with screws 16, thereby being connected to the mounting portion 12. The legs 13 may be provided only at least one end of the mounting portion 12 to support the mounting portion 12 .

[0018] (3) Storage section 14 The storage section 14 is provided on either the first end or the second end of the mounting section 12 where the legs 13 are provided, and is capable of storing an electronic device. In the display base 11 shown in Fig. 1 to Fig. 4, as an example, the storage section 14 is provided on the second end side of the mounting section 12 where the legs 13-2 are provided. Note that the position at which the storage section 14 is provided is not limited to this example, and it may be on the first end side of the mounting section 12 where the legs 13-1 are provided. The electronic devices housed inside the housing section 14 include, for example, a sound collection device (sound collection section), equipment used to convert sound (sound processing section), hubs (equipment connection sections) and cables for connecting each device, and power cables for supplying power to electronic devices other than the transparent display.

[0019] As shown in FIG. 1 to FIG. 4, the storage section 14 includes a storage cover section 141 and a storage cover section 142. The storage cover section 141 is provided on the first main surface side where the first main surface of the transparent display is located. On the other hand, the storage cover section 142 is provided on the second main surface side where the second main surface, which is the main surface opposite to the first main surface of the transparent display, is located. The storage cover section 141 and the storage cover section 142 are fixed to at least one of the placement section 12, the leg section 13, and the tray section 15 by a fixing device. The fixing device is, for example, a fastener, a screw, or the like. Note that the fixing method of the storage cover section 141 and the storage cover section 142 is not limited to fixing by a fixing device. For example, the storage cover section 141 and the storage cover section 142 may be fixed by fitting.

[0020] The accommodation portion 14 is provided with a notch portion 143, a notch portion 144, a notch portion 145, and a notch portion 146. The cutout portion 143 is provided in the upper portion of the housing cover portion 141 in order to expose the sound collection portion of the sound collection device that collects the voice of the user on the first main surface side to the outside of the housing portion . The cutout portion 144 is provided in the upper part of the housing cover portion 142 in order to allow the sound collection portion of the sound collection device, which collects the voice of a user on the second main surface side, to pass outside the housing portion 14. The cutout portion 144 also serves to pass the video cable and power cable of the transparent display placed on the placement portion 12 into the inside of the housing portion 14. For this reason, the shape of the cutout portion 144 is set to be larger than the cutout portion 143. The cutout portion 145 is provided in the lower part of the side surface of the housing cover portion 142 in order to take out the power cable housed inside the housing portion 14 and the power cable of the transparent display passed through the cutout portion 144 into the housing portion 14 to the outside of the housing portion 14 and connect them to a power source. Specifically, this side surface is the side surface on the rear side of the display base 11. The notch 146 is provided in the lower part of the side surface of the storage unit 14 in order to expose a connection terminal for connecting an electronic device stored inside the storage unit 14 to an electronic device provided outside the storage unit 14. Specifically, this side surface faces the end side opposite to the end of the placement unit 12 where the storage unit 14 is provided.

[0021] The accommodation section 14 may be provided so as to support the mounting section 12. For example, when the legs 13 are provided only at either the first end or the second end of the mounting section 12, the accommodation section 14 is provided so as to support the mounting section 12 at the end side of the mounting section 12 where the legs 13 are not provided.

[0022] (4) Tray section 15 The tray section 15 supports the entire display base 11. The length of the tray section 15 in the longitudinal direction is set to a length corresponding to the length of the placement section 12. One leg section 13 is connected to a third end, which is one end in the longitudinal direction of the tray section 15, and the other leg section 13 and the storage section 14 are connected to a fourth end, which is the end opposite to the third end. In the display base 11 shown in FIG. 1 to FIG. 4, as an example, the leg section 13-1 is connected to the third end of the tray section 15 by being fixed with a screw 16, and the leg section 13-2 and the storage section 14 are connected to the fourth end of the tray section 15 by being fixed with a screw (not shown). In this way, the tray section 15 supports the entire display base 11 including the placement section 12, the leg section 13, and the storage section 14.

[0023] Regarding the size of the tray part 15, the length in the longitudinal direction is set to a value within a range of 300 mm to 700 mm, for example, and the length in the lateral direction (depth direction of the display base 11) is set to a value within a range of 150 mm to 300 mm. Note that the length of the tray part 15 along the thickness direction of the transparent display 50 is set to be longer than the length of the placement part 12 in the thickness direction. The weight of the tray unit 15 is set so that the center of gravity of the entire unit, including the transparent display 50 and the display base 11 on which the transparent display 50 is placed, is lower than the placement surface of the placement unit 12. The center of gravity is set, for example, lower than the placement surface AR1 shown in FIG.

[0024] 2, in the longitudinal direction of the mounting portion 12, the leg portion 13-1 and the housing portion 14 are spaced apart from each other, and a spaced apart space AR2 is formed between the leg portion 13-1 and the housing portion 14. The space AR2 is also a space that penetrates in the direction between the first main surface side and the second main surface side of the transparent display (the depth direction of the mounting portion 12).

[0025] 3, the tray unit 15 is provided with a placement surface AR3 that is visible from the first and second main surfaces of the transparent display and on which an object can be placed. The placement surface AR3 is formed in a portion of the tray unit 15 that corresponds to the space AR2 between the leg 13-1 and the storage unit 14. For example, a first operation terminal shared by a first user on the first main surface side and a second user on the second main surface side can be placed on the placement surface AR3. For this reason, the size of the placement surface AR3 may be set according to the size of the first operation terminal to be placed on the placement surface AR3. The electronic device housed inside the housing portion 14 is communicatively connected to the first operation terminal via a connection terminal arranged outside the housing portion 14 from the cutout portion 146.

[0026] Also, a recess may be formed in the center of the placement surface AR3 of the tray unit 15. The size of the recess may be set to be the same as the size of the placement surface AR3. By providing the recess in the placement surface AR3, it is possible to prevent the first operation terminal placed in the recess from shifting when the first user or the second user operates the first operation terminal placed in the recess. Also, since the recess in the placement surface AR3 prevents the first operation terminal from shifting, it is possible to prevent the first operation terminal from falling when the display base 11 is transported.

[0027] Note that a gripping portion 151 may be formed at an end in the longitudinal direction of the tray portion 15 so as to be recessed so as to be grippable when transporting the display base 11. Note that the gripping portion 151 may be formed at the end of the tray portion 15 by processing the end of the tray portion 15 itself to make it recessed, or the gripping portion 151 may be formed by connecting a component to the bottom surface of the tray portion 15 and making the end of the tray portion 15 including the component into a recessed shape. Furthermore, a material (for example, rubber) may be provided on the rear surface of the tray unit 15 (the surface that comes into contact with the installation location) to prevent it from falling over.

[0028] In the display base 11 described above, the transparent display can be set up vertically on the mounting portion 12. As a result, the display base 11 can provide a higher installation position for the transparent display compared to a case where the transparent display is installed without using a base. As a result, the transparent display is installed so that the position of the user's face is located within the screen of the transparent display, and is provided to separate the first user and the second user. In this way, since the transparent display is installed between the first user and the second user, it is possible to prevent droplets and the like from being directly scattered on the other user. The display base 11 may have an adjustment mechanism capable of changing the distance between the placement portion 12 and the tray portion 15. The adjustment mechanism may be capable of adjusting the height of the legs 13 themselves, may be capable of adjusting the height of the storage portion 14 itself, or may be capable of adjusting the fixed position of the placement portion 12. The adjustment mechanism can adjust the position of the transparent display so that the position of the user's face is located within the screen of the transparent display according to differences in the user's height, sitting height, etc.

[0029] In addition, in the display base 11, a space AR2 formed between the leg 13-1 and the storage unit 14 penetrates between the first user side and the second user side. This allows the first user and the second user to exchange documents, slips, and other submissions in the space AR2. Furthermore, the height of the space AR2 is the same as the height of the storage unit 14, and can also be adjusted by an adjustment mechanism. This allows the first user and the second user to easily operate the first operation terminal and exchange submissions, etc., since the height of the space AR2 is sufficiently secured.

[0030] In addition, the display base 11 is a tray-integrated base by connecting the placement section 12, the legs 13, the storage section 14, and the tray section 15. This allows the user to transport the display base 11, the transparent display placed on the placement section 12, the electronic device stored in the storage section 14, and the first operation terminal placed on the tray section 15 all together when transporting the display base 11, making transportation efficient. In the case of a base that is not a tray-integrated base, the electronic device and the first operation terminal are placed directly on a table (e.g., a reception table) on which the display base 11 on which the transparent display is placed is placed. In this case, the user needs to transport the display base 11 on which the transparent display is placed, and the electronic device and the first operation terminal separately, resulting in poor transportation efficiency.

[0031] <<2. Examples of using display pedestals>> The configuration of the display base 11 according to this embodiment has been described above. Next, a usage example of the display base 11 according to this embodiment will be described with reference to FIGS.

[0032] <2-1. Overview of display stand usage> 5 is a diagram for explaining an outline of how the display base 11 according to this embodiment is used. The display base 11 according to this embodiment is used with, for example, a transparent display 50 mounted thereon. As shown in FIG. 5, a device in which the transparent display 50 is mounted on the display base 11 is used, for example, as a conversation assistance device 10. When the transparent display 50 is mounted on the display base 11, a tray portion 15 of the display base 11 supports the entire conversation assistance device including the transparent display 50.

[0033] The conversation assistance device 10 is used, for example, in a conversation assistance system. The conversation assistance system has a function as a partition for preventing droplets and crime, and also has a function of visualizing the conversation as characters in real time by instantly converting input conversation contents into characters and displaying them on the partition portion (transparent display 50). Since the partition portion is transparent, the user in the conversation can also see the facial expression of the conversation partner. Therefore, the conversation display system has a mechanism that allows the user to communicate smartly.

[0034] The conversation display system is used, for example, in the business of counters in municipalities, stores, stations, etc. In this case, the conversation assistance device 10 is provided between a first user (e.g., a resident U1) and a second user (e.g., an operator U2) as shown in Fig. 5. In the following, the present embodiment will be described by taking as an example an example in which the first user is a resident U1 and the second user is an operator U2.

[0035] As shown in FIG. 5, conversation assistance device 10 includes display base 11, sound collection device 20, transparent display 50, and tablet terminal 60 (an example of a first operation terminal) mounted thereon.

[0036] A transparent display 50 is placed on the placement unit 12. In the example shown in Fig. 5, the transparent display 50 is installed such that a first main surface side thereof faces a user U1, and a second main surface side thereof, which is a main surface opposite to the first main surface of the transparent display 50, faces an operator U2. Fig. 6 is a rear view of the conversation assistance device 10 in which the transparent display 50 is mounted on the display base 11 according to this embodiment. As shown in Fig. 6, the transparent display 50 is mounted on the mounting portion 12 by inserting a portion of the control unit 52 excluding the display unit 51 from an opening in the upper part of the mounting portion 12. Note that, in the transparent display 50 mounted on the display base 11, the portion of the control unit 52 inserted into the mounting portion 12 may be in a state in which only the first main surface side is covered by the mounting portion 12 and the second main surface side is not covered, as shown in Fig. 6.

[0037] The housing section 14 houses, for example, a sound collector 20, an audio interface (not shown), a Universal Serial Bus (USB) hub (not shown), and connection cables (not shown) that connect the various devices. The sound collection device 20 (sound collection processing unit) collects a sound uttered from at least one of the first main surface side or the second main surface side of the transparent display 50. As shown in Fig. 5, the sound collection unit 21 of the sound collection device 20 is protruded outside the accommodation unit 14 to collect the sound of the speaking user. The audio interface (audio processing unit) converts the sound collected by the sound collection device 20 into audio data. The USB hub (device connection section) connects the tablet terminal 60 (operation terminal) that obtains text data by processing voice data to the transparent display 50, and causes the transparent display 50 to display the text data.

[0038] 5, for example, a tablet terminal 60 is placed on the placement surface AR3 of the tray part 15. In this case, on the placement surface AR3, the length of the tray part 15 along the thickness direction of the transparent display 50 is set to be longer than the length of the tablet terminal 60 in the short direction, and the length of the tray part 15 along the horizontal direction of the main surface of the transparent display 50 is set to be longer than the length of the tablet terminal 60 in the long direction.

[0039] <2-2. Configuration of conversation display system> The outline of how to use the display base 11 according to this embodiment has been described above. Next, the configuration of the conversation display system according to this embodiment will be described with reference to Fig. 7 and Fig. 8.

The transparent display 50 is connected to the USB hub 40 via, for example, an HDMI (High-Definition Multimedia Interface; registered trademark) cable. As a result, the transparent display 50 receives data of a conversation screen showing the contents of the conversation from the tablet terminal 60 via the USB hub 40, and displays the conversation screen. The power cable of the transparent display 50 is connected to the external power source 70 through the inside of the housing portion 14. Thus, the transparent display 50 is supplied with power from the external power source 70.

[0049] The transparent display 50 is a display that has a degree of transparency that allows users to see each other's facial expressions. Therefore, since users can check the facial expressions of the other user, face-to-face communication is not obstructed. In addition, since the transparent display 50 has transparency, the background (the other user) can be seen through, and thus the display does not visually obstruct the view, blends into the surrounding environment, and enables a variety of expressions, such as displaying an image superimposed on the real object (the other user), thereby expanding the scope of communication.

[0050] The screen size of the transparent display 50 has an area large enough to function as a partition, and may be, for example, about 10 to 50 inches. The transparent display 50 can display various information other than the conversation screen. This allows various video expressions to be used to broaden the scope of communication.

[0051] (1-5) 60 tablet devices The tablet terminal 60 is a terminal shared by the resident U1 and the operator U2, and is an example of a first operation terminal. The tablet terminal 60 is placed on the placement surface AR3 of the tray unit 15. Therefore, the resident U1 can operate the tablet terminal 60 from the first main surface side of the transparent display 50, and the operator U2 can operate the tablet terminal 60 from the second main surface side of the transparent display 50. The tablet terminal 60 is connected by wire to the USB hub 40 inside the housing section 14. The tablet terminal 60 is connected to the USB hub 40 via, for example, a USB cable. The tablet terminal 60 is also connected to the multilingual translation device 80 via the network NW so as to be able to communicate with each other.

[0052] On the tablet terminal 60, various screens are displayed by an application (hereinafter also referred to as a "conversation assistance app") for functioning as a terminal that assists the conversation between the resident U1 and the operator U2. The function of the conversation assistance app may be provided by installing the conversation assistance app on the tablet terminal 60 (i.e., a native app), or may be provided by a Web system (i.e., a Web app). In the case of a Web system, the function of the conversation assistance app is provided via a Web browser.

[0053] A first operation area operated by the resident U1 and a second operation area operated by the operator U2 are displayed on the tablet terminal 60. For example, the first operation area and the second operation area are displayed on the same screen on the tablet terminal 60. This allows the operator U2 to check how the resident U1 is operating the screen on the terminal that he or she operates, and therefore allows the operator U2 to easily support the operation of the resident U1.

[0054] In the first operation area, an operation menu for the user U1 is displayed, such as for selecting an input means or a language. In the second operation area, an operation menu for the operator U2 is displayed, such as for setting the conversation assistance device 10, setting the display on the transparent display 50, or switching the display.

[0055] In selecting the input means, the resident U1 can select either voice input or keyboard input. Therefore, a resident U1 who has no trouble speaking can input the contents of the conversation by speaking by selecting voice input on the tablet terminal 60. On the other hand, a resident U1 who has difficulty speaking can input the contents of the conversation by typing by selecting keyboard input on the tablet terminal 60. This allows even a resident U1 who has difficulty speaking, such as a person with hearing loss or speech impairment, to communicate with the operator U2 through conversation.

[0056] When the conversation content is input by voice input, the tablet terminal 60 receives voice data from the audio interface 30 via the USB hub 40. The tablet terminal 60 transmits the voice data to the multilingual translation device 80 via the network NW, and receives the translation result of the conversation content indicated by the voice data from the multilingual translation device 80. The tablet terminal 60 transmits data of a conversation screen that displays the translation result to the transparent display 50, and causes it to be displayed.

[0057] In selecting the language, the resident U1 can select the language to be used for input. The selectable languages ​​include, but are not limited to, Japanese, English, Chinese (simplified characters), Chinese (traditional characters), Korean, Indonesian, Spanish, Thai, Filipino, French, Vietnamese, Portuguese, and Burmese. When keyboard input is selected as the input method, a digital keyboard of the language selected from these languages ​​is displayed on the tablet terminal 60. Therefore, the resident U1 who uses a language different from that of the operator U2 can input the conversation content in his / her own language by selecting the language he / she uses on the tablet terminal 60. As a result, even if the resident U1 uses a language different from that of the operator U2, he / she can communicate with the operator U2 through conversation.

[0058] When the conversation content is input by keyboard input, the tablet terminal 60 acquires text data indicating the conversation content input by typing from the digital keyboard. The tablet terminal 60 transmits the text data to the multilingual translation device 80 via the network NW, and receives the translation result of the conversation content indicated by the text data from the multilingual translation device 80. The tablet terminal 60 transmits data of a conversation screen that displays the translation result to the transparent display 50, and causes it to be displayed.

[0059] Furthermore, by having the resident U1 and the operator U2 share the tablet terminal 60, there is no need to provide multiple tablet terminals 60, which makes it possible to secure space for other uses and prevent the wiring from becoming complicated.

[0060] (2) Multilingual translation device 80 The multilingual translation device 80 is a device that translates conversation content expressed in a language used by one user into conversation content expressed in a language used by another user. The multilingual translation device 80 is configured, for example, by one or more PCs (Personal Computers) and server devices (for example, cloud servers).

[0061] The multilingual translation device 80 is communicably connected to the tablet terminal 60 via the network NW. As a result, the multilingual translation device 80 receives voice data or text data from the tablet terminal 60 and transmits the translation results of each data to the tablet terminal 60. When the contents of the conversation are input by voice input, the multilingual translation device 80 receives voice data from the tablet terminal 60 and performs voice recognition processing on the voice data. The multilingual translation device 80 converts the voice represented by the voice data into characters through the voice recognition processing, and generates text data representing the characters. The multilingual translation device 80 performs translation processing on the text data obtained by the voice recognition processing. When the conversation content is input by keyboard input, the multilingual translation device 80 receives the text data from the tablet terminal 60 and executes a translation process on the text data.

[0062] <2-3. Screen display example> A screen display on the transparent display 50 according to the present embodiment will be described with reference to Fig. 9. Fig. 9 is a diagram showing an example of a screen display on the transparent display 50 according to the present embodiment. Fig. 9 shows, as an example, a conversation screen as viewed from the first main surface side (resident U1 side) of the transparent display 50. Note that, in the example shown in Fig. 9, a case will be described in which the resident U1 speaks English and the operator U2 speaks Japanese.

[0063] The conversation screen G4 shown in FIG. 9 is a screen displayed on the transparent display 50 when the resident U1 and the operator U2 are having a conversation. In the example shown in FIG. 9, as an example, in the left-right direction of the conversation screen G4, the conversation contents (first character information) of the resident U1 are displayed in chronological order in the up-down direction at the left end, and the conversation contents (second character information) of the operator U2 are displayed in chronological order in the up-down direction at the right end. In the conversation screen G4, the tail of the speech bubble is directed to the outside or center of the conversation screen G4, thereby distinguishing whether the conversation contents are those of the resident U1 or the operator U2. For example, when viewed from the first main surface side (the resident U1 side) of the transparent display 50, a speech bubble with its tail directed to the outside of the conversation screen G4 indicates the conversation contents of the resident U1, and a speech bubble with its tail directed to the center indicates the conversation contents of the operator U2. When viewed from the second main surface side (operator U2 side) of the transparent display 50, the speech bubble with its tail pointing outward on the conversation screen G4 indicates the conversation content of operator U2, and the speech bubble with its tail pointing toward the center indicates the conversation content of resident U1.

[0064] The speech bubbles F1 and F2 display the conversation contents input by the operator U2. When the operator U2 voice-inputs "Hello" in Japanese, a speech bubble F1 showing "Hello" in Japanese is generated and displayed on the second main surface side of the transparent display 50. In addition, "Hello" is translated from Japanese to English, and a speech bubble F2 showing "Hello." is generated and displayed on the first main surface side of the transparent display 50.

[0065] The speech bubbles F3 and F4 display the conversation contents input by the operator U2 in succession. When the operator U2 voice-inputs "How is it today?" in Japanese, a speech bubble F3 showing "How is it today?" in Japanese is generated and displayed on the second main surface side of the transparent display 50. In addition, "How is it today?" is translated from Japanese to English, and a speech bubble F4 showing "What brings you here today?" is generated and displayed on the first main surface side of the transparent display 50.

[0066] The speech bubbles F5 and F6 display the conversation content entered by the consumer U1. When the consumer U1 voice-inputs or keyboard-inputs "Please tell me a recommended Japanese restaurant around?" in English, a speech bubble F5 indicating "Please tell me a recommended Japanese restaurant around?" in English is generated and displayed on the first main surface side of the transparent display 50. In addition, "Please tell me a recommended Japanese restaurant around?" is translated from English to Japanese, and a speech bubble F6 indicating "Please tell me a recommended Japanese restaurant around here" is generated and displayed on the second main surface side of the transparent display 50.

[0067] The above describes examples of use of the display base 11 according to the present embodiment. As described above, the display base 11 according to this embodiment includes the mounting portion 12 on which one side along the horizontal direction of the main surface of the transparent display 50 can be placed and which is set to a length corresponding to the one side, the legs 13 provided at a first end which is one end of the mounting portion 12 and a second end which is the end opposite to the one end and which support the mounting portion 12, the storage portion 14 provided at either the first end or the second end of the mounting portion 12 and capable of storing an electronic device, and the tray portion 15 which is set to a length corresponding to the longitudinal direction of the mounting portion 12, has one leg 13 connected to a third end which is one end, and has the other leg 13 and the storage portion 14 connected to a fourth end which is the end opposite to the third end, is visible from a first main surface side on which the first main surface of the transparent display 50 is located and a second main surface side on which the second main surface which is the main surface opposite to the first main surface is located, and has a mounting surface on which an object can be placed.

[0068] With this configuration, the display can be placed at a high position so that characters can be displayed at the position of the other person's face, allowing the user to talk while seeing the other person's facial expression, and the display is stably supported to prevent it from falling over. In addition, since all of the attached electronic devices are placed on the display base 11, the display can be easily moved with all of the electronic devices still connected. Therefore, the display base 11 according to this embodiment can improve the convenience of the transparent display.
