Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, in most cases, two-dimensional display objects such as printed matter and monitors have been used to attract people's attention. However, it is difficult to give a strong impact only by using a two-dimensional display object, and furthermore, depending on the viewing direction, the content of the display object may not be grasped. In addition, there is a case where a printed matter is attached to the side surface of a columnar (for example, a substantially triangular prism-shaped) three-dimensional object and used, but it is still difficult to sufficiently attract the attention of people around. Therefore, a technology that can more sufficiently attract the attention of people around is desired.

[0005] A typical object of the present disclosure is to solve at least one of the above problems and provide a three-dimensional display object and a production method that can sufficiently attract the attention of people around.

Means for Solving the Problems

[0006] A typical embodiment of the present disclosure provides a three-dimensional display that is placed on a mounting surface and has an information display section on its outside on which information is displayed, and a volmatrix positioned above the mounting surface of the three-dimensional part and causing the real image of an object placed inside to appear as if it is floating in the air, wherein the volmatrix comprises a lower concave mirror positioned with its concave surface facing upward and on which the object is placed, and an upper concave mirror positioned opposite the concave surface of the lower concave mirror with its concave surface facing downward and having an opening at the focal point of the lower concave mirror. The three-dimensional part surrounds and shields at least the side of the lower concave mirror in the volmatrix with the information display section.

[0007] A typical embodiment of the present disclosure provides a presentation method implemented in a restaurant, the restaurant comprising: a transport device for transporting food and beverages on a transport path; and a three-dimensional display object, the three-dimensional display object comprising: a three-dimensional part placed on a mounting surface and having an information display section on its outside on which information is displayed; and a volumatrix positioned above the mounting surface of the three-dimensional part and causing the real image of an object installed inside to appear as if floating in the air, the volumatrix comprising: a lower concave mirror positioned with its concave surface facing upward and on which the object is placed; and an upper concave mirror positioned opposite the concave surface of the lower concave mirror with its concave surface facing downward and having an opening at the focal point of the lower concave mirror, the three-dimensional part surrounds and shields at least the side of the lower concave mirror in the volumatrix with the information display section, the three-dimensional display object is placed on the transport path and transported along the route of the transport path to perform the presentation.

[0008] According to the three-dimensional display and presentation method described herein, it is possible to attract sufficient attention from people in the surrounding area. [Brief explanation of the drawing]

[0010] <Overview> The three-dimensional display illustrated in this disclosure comprises a three-dimensional section and a volumatrix. The three-dimensional section is placed on a mounting surface on which the three-dimensional display is installed and has an information display section on its exterior on which information is displayed. The volumatrix is ​​positioned above the mounting surface of the three-dimensional section and allows the real image of an object installed inside to be observed as if floating in mid-air. In detail, the volumatrix comprises a lower concave mirror and an upper concave mirror. The lower concave mirror is positioned so that its concave surface faces upward. An object is placed on the concave surface of the lower concave mirror. The upper concave mirror is positioned opposite the concave surface of the lower concave mirror so that its concave surface faces downward. An opening is formed in the upper concave mirror at the focal point of the lower concave mirror. The three-dimensional section surrounds and shields at least the side of the lower concave mirror in the volumatrix with the information display section.

[0011] According to the three-dimensional display of this disclosure, firstly, an object placed inside the volumatrix appears to be floating in the air near the opening of the upper concave mirror. Therefore, people in the vicinity will be strongly interested in the object that appears to be floating, making it easy to attract their attention. As a result, the information display section surrounding the sides of the volumatrix will also attract the attention of people in the vicinity, so by utilizing the volumatrix as a means of advertising or performance using the information display section, it is possible to efficiently enhance the effect of advertising or performance. In addition, since the volumatrix is ​​positioned above the installation surface in the three-dimensional part, the posture of the volumatrix is ​​more stable compared to when the lower concave mirror of the volumatrix is ​​placed directly on the installation surface. The position of the volumatrix from the installation surface is also higher, so the real image of the object formed by the volumatrix becomes even more conspicuous. Furthermore, the information display section of the three-dimensional part surrounds and shields the sides of the lower concave mirror of the volumatrix. As a result, it becomes difficult for those around to grasp the structure of the volmatrix (a structure that forms a real image of an object by combining a lower concave mirror and an upper concave mirror), leading them to observe the real image of the object with great interest. The deterioration in appearance caused by the exposure of the lower concave mirror is also suppressed. Therefore, the three-dimensional display object of this disclosure can attract the attention of those around it.

[0012] The information display unit illustrated in this disclosure completely shields the entire circumferential side of the lower concave mirror in a cylindrical shape without any gaps. As a result, the configuration in which the volmatrix forms a real image of an object becomes even more difficult to grasp. However, the information display unit may surround the side of the lower concave mirror in a cylindrical shape with gaps in at least a portion of the circumferential direction. Similarly, the information display unit does not have to shield the entire vertical range of the side of the lower concave mirror of the volmatrix. In other words, a portion of the lower concave mirror in the vertical direction may be exposed to the outside. Even in this case, the configuration of the volmatrix becomes more difficult to grasp than when the information display unit is not provided.

[0013] The opening of the upper concave mirror (i.e., the position where the real image of the object is formed) may be located at the very top of the three-dimensional display. In this case, the real image formed in the opening becomes more easily visible from the outside. Also, it becomes easier for people nearby to try to touch the real image, thus attracting even more attention to it.

[0014] Furthermore, the vertical length (height) of the three-dimensional section may be greater than or equal to the vertical length of the lower concave mirror of the volmatrix, and more preferably greater than or equal to the vertical length of the entire volmatrix. In this case, the small real image formed by the volmatrix can attract attention while the information attached to the information display section of the three-dimensional section can be made larger for those around it. Therefore, the effects of advertising or performances using the information display section become even easier to achieve.

[0015] The outer surface of the information display unit may be adorned with information including at least one of the following: photographs, text, and pictures (including designs such as patterns). In this case, the information display unit not only shields the lower concave mirror of the volumatrix from people in the vicinity, but also allows people in the vicinity to see the information attached to its outer surface. Thus, the usefulness of the three-dimensional display is further improved.

[0016] For example, advertising information may be attached to the outer surface of the information display section. In this case, businesses such as restaurants can attract customers' attention to the three-dimensional display through the real image of the object projected by the volmatrix, making the advertising information attached to the information display section of the three-dimensional display more easily visible to customers. Therefore, the effectiveness of the advertising is likely to improve.

[0017] Furthermore, information related to the object installed in the volumatrix may be attached to the outer surface of the information display unit. In this case, the association between the information attached to the outside of the information display unit and the object becomes stronger, making it easier for people in the vicinity to focus their attention on the 3D display. For example, if an object of a marine organism is used, it is conceivable to use underwater photographs or drawings as information related to the object.

[0018] However, even when at least one of a photograph, characters, or a picture is not attached to the information display unit (for example, when only a single color is attached to the information display unit, or when only a pattern is attached), the structure of the matrix becomes difficult to grasp because the periphery of the lower concave mirror of the matrix is shielded.

[0019] The three-dimensional part may further include a light-transmitting member and an internal member. The light-transmitting member is arranged in a cylindrical shape centered on an axis extending in the vertical direction in a state where the inside can be visually recognized from the outside. The internal member is arranged inside the light-transmitting member with a gap formed between the internal member and the light-transmitting member. A sheet-like information display unit may be arranged in the gap between the light-transmitting member and the internal member.

[0020] In this case, the information display unit only needs to be arranged in the gap between the light-transmitting member and the internal member without using an adhesive or the like, so it is also easy to remove the information display unit from the gap. Therefore, the operator can replace the information display unit more easily than in the case where the information display unit is attached to the three-dimensional part by a seal or an adhesive or the like. Therefore, even when it is necessary to change the information outside the information display unit, or when deterioration, dirt, or the like occurs in the information display unit, the operator can easily replace the information display unit to deal with it.

[0021] When viewing the three-dimensional display object from the direction along the axis of the cylindrical light-transmitting member (for example, upward), the gap between the light-transmitting member and the internal member may be connected in a ring shape. In this case, the operator can insert the information display unit at any position in the annular gap, so the workability is further improved. However, the gap between the light-transmitting member and the internal member may be divided into a plurality of regions. In this case, it is also possible to separately arrange the information display units in each of the divided regions.

[0022] When using a sheet-like information display unit, various materials such as paper, resin, and metal can be used for the information display unit. Alternatively, a flexible sheet-like display capable of displaying various images and being deformable may be used as the information display unit. In this case, various types of information can be easily displayed on the information display unit. It also becomes possible to display moving images.

[0023] The internal members of the three-dimensional section may support the volumatrix. A gap may be formed between the volumatrix, which is supported by the internal members, and the light-transmitting member. In this case, the worker can insert the information display unit between the light-transmitting member and the internal members through the gap between the volumatrix and the light-transmitting member, and can also remove the information display unit, without removing the volumatrix from the internal members (i.e., while the volumatrix remains supported by the internal members). Therefore, work efficiency can be further improved.

[0024] The specific method for forming a gap between the volumatrix and the light-transmitting member can be appropriately selected. For example, by making the height of the upper end of the internal member higher than the height of the upper end of the light-transmitting member, a gap may be formed between the volumatrix, which is supported by the upper end of the internal member, and the light-transmitting member. Alternatively, by making the diameter of the cylindrical light-transmitting member larger than the diameter of the volumatrix in a plan view, a gap may be formed between the volumatrix and the light-transmitting member.

[0025] The internal members of the three-dimensional section may support the volumatrix. The shape of the side surface of the internal member and the shape of the light-transmitting member may both be cylindrical with an axis extending in the vertical direction. The lower concave mirror of the volumatrix is ​​circular when viewed from the bottom. Therefore, by making the shape of the side surface of the internal member cylindrical (for example, forming the internal member itself in a cylindrical shape), the lower concave mirror of the volumatrix is ​​more easily supported in a stable state. Also, by making the shape of the light-transmitting member cylindrical, it becomes easier to make the width of the gap between the internal member and the light-transmitting member more uniform, so that the information display section is more easily held stably. For example, by aligning the axis of the side surface of the cylindrical internal member with the axis of the cylindrical light-transmitting member, it is possible to appropriately make the width of the gap between the internal member and the light-transmitting member more uniform. In addition, the information attached to the outside of the information display section becomes more easily visible from any position in the circumferential direction.

[0026] However, it is possible to change the specific configuration of the internal components. For example, the shape of the internal components may be a rectangular tube or the like. Similarly, the shape of the light-transmitting component may also be a rectangular tube or the like. Furthermore, the internal components may not be cylindrical, but rather roughly columnar (cylindrical or rectangular prism). In this case, the upper part of the columnar internal component may be concave downwards. The lower concave mirror of the volumatrix is ​​placed on the downwardly concave portion, thereby stably supporting the volumatrix with the internal components. Alternatively, the internal components may be formed by arranging multiple rod-shaped components in a row. Even in this case, the information display unit is properly mounted on the three-dimensional part by forming an appropriate gap between the internal components and the light-transmitting component.

[0027] The upper concave mirror of the volmatrix may have a marking on the part exposed to the outside to draw attention to the opening. In this case, people in the vicinity can more easily focus on the real image of the object formed in the opening of the upper concave mirror by looking at the marking on the upper concave mirror. Therefore, the attention of people in the vicinity can be more strongly drawn to the three-dimensional display.

[0028] The specific configuration of the attention indicator can be selected as appropriate. For example, text such as "Pay Attention Here," symbols such as arrows, or a picture of a human finger may be used as the attention indicator. Alternatively, the attention indicator may be applied by coloring the area near the opening of the exposed portion of the upper concave mirror with a different color from the rest of the mirror.

[0029] The three-dimensional display can be placed on a transport path capable of carrying food and beverages, and transported along the path. In this case, the attention of customers near the transport path can be strongly directed towards the three-dimensional display moving along the transport path. Therefore, it is possible to entertain customers who visit the store.

[0030] Furthermore, objects transported along a transport path (e.g., three-dimensional displays and plates) often rotate while moving along the path. Therefore, customers near the transport path have more opportunities to see the real image of the object projected by the volmatrix from various angles, making it easier to attract their attention. In particular, if the transport path includes curves, the three-dimensional displays are more likely to rotate during transport. However, even when transporting three-dimensional displays on a transport path without curves, it is still easier to appropriately attract customer attention.

[0031] The transport path is capable of transporting plates on which food and beverages are placed. The outer diameter of the lower end of the three-dimensional section that rests on the installation surface of the transport path may be within ±30% (preferably ±20%) of the outer diameter of the lower end of the raised base extending downward from the plate surface of the plate being transported by the transport path. In this case, the three-dimensional display object will also be transported more smoothly by the transport path, just like the plate. It is also possible to install the light-transmitting member and internal member that constitute the three-dimensional section on top of the plate on which food and beverages are placed. In this case as well, the three-dimensional display object will also be transported more smoothly, just like the plate.

[0032] The object may be placed on the lower concave mirror via a colored holding member (for example, a colored gel-like or resin-based member that transmits light). In this case, the color of the holding member will also appear near the real image of the object being imaged, making it easier to attract the attention of people in the vicinity.

[0033] The volumatrix may be detachably installed on the three-dimensional part. In this case, the worker can easily separate the three-dimensional part of the three-dimensional display from the volumatrix, making it easy to perform maintenance on the three-dimensional display (e.g., cleaning, disinfection, replacement of parts, etc.).

[0034] Furthermore, the three-dimensional display may include fixing members that secure the volumatrix to the three-dimensional part, with the volumatrix detachably installed on the three-dimensional part. In this case, during maintenance, the fixing members can be released, allowing for easy separation of the three-dimensional part and the volumatrix of the display. Also, when using the three-dimensional display, the volumatrix is ​​fixed to the three-dimensional part, making it less likely for problems such as the volumatrix falling from the three-dimensional part to occur if someone nearby touches the display.

[0035] However, the volumatrix may be fixed to at least one of the three-dimensional parts other than the information display section. For example, the three-dimensional parts other than the information display section may be manufactured in a state where they are pre-integrated with the volumatrix. Even in this case, the attention of people in the surrounding area will be appropriately drawn to the three-dimensional display.

[0036] The three-dimensional display may include an object rotation unit (e.g., a motor) that rotates the object placed on the volmatrix. In this case, the actual image of the object projected by the volmatrix also rotates, making it easier to attract the attention of people in the surrounding area.

[0037] Furthermore, the three-dimensional display may include an overall rotation unit (e.g., a motor) that rotates at least the information display unit and the volmatrix (e.g., the three-dimensional part on which the volmatrix is ​​placed) around an axis extending in the vertical direction. In this case, since the information display unit rotates in addition to the actual image of the object formed by the volmatrix, it becomes even easier to attract the attention of people in the vicinity. It is also possible to have multiple characters attached to the information display unit and rotate the information display unit by the overall rotation unit to allow the characters to be read sequentially.

[0038] The three-dimensional display may also be equipped with an illumination light source to light up the object placed on the volmatrix. In this case, the real image of the object formed by the volmatrix is ​​also illuminated, making it more likely to attract the attention of people in the surrounding area.

[0039] It is also possible to use only the parts of the three-dimensional display exemplified in this disclosure other than the volumatrix (for example, the light-transmitting member, internal member, and information display section of the three-dimensional part). Even in this case, the worker can easily replace the information display section compared to cases where the information display section is attached to the three-dimensional part with a seal or adhesive. In this case, the three-dimensional display can also be represented as follows.

[0040] A three-dimensional display object comprising: a light-transmitting member arranged in a cylindrical shape with an axis extending in the vertical direction, such that the interior can be seen from the outside; an internal member arranged inside the light-transmitting member, with a gap formed between it and the light-transmitting member; and an information display unit, which is in the form of a sheet, is placed in the gap between the light-transmitting member and the internal member, and displays information on the outside.

[0041] <Embodiment> (Schematic configuration) Hereinafter, one typical embodiment of the present disclosure will be described with reference to the drawings. First, with reference to Figure 1, the overall schematic configuration of the three-dimensional display object 1 of this embodiment will be described. Figures 6 and 7 also show perspective views of an actual prototype of the three-dimensional display object 1, so please also refer to Figures 6 and 7. As shown in Figures 1 and 6, the three-dimensional display object 1 comprises a volmatrix 10 and a three-dimensional section 30. The volmatrix 10 (sometimes referred to as a 3D mirror scope, etc.) arranges two concave mirrors facing each other with their edges aligned, so that an object 17 (see Figure 2) placed at the focal point of one concave mirror appears to be at the focal point of the other concave mirror (see Figures 2, 6, and 7). In other words, the volmatrix 10 allows people around to observe the real image 17R of the object 17 installed inside as if it were floating in the air. The three-dimensional section 30 is placed on an installation surface (in this embodiment, the transport path 102 of the transport device 101 illustrated in Figure 5). The volmatrix 17 is positioned above the mounting surface on which the three-dimensional display object 1 is installed within the three-dimensional section 30. Furthermore, the three-dimensional section 30 is shielded by surrounding at least a portion of the sides of the volmatrix 10 with an information display section 60 on which information is displayed on the outside.

[0042] (Volmatrix) The Volmatrix 10 will be described in detail with reference to Figure 2, etc. The Volmatrix 10 comprises a lower concave mirror 11 and an upper concave mirror 12. In this embodiment, the lower concave mirror 11 is positioned so that its concave surface faces upward. An object 17 is placed on the concave surface of the lower concave mirror 11 (more specifically, near the focal point of the lower concave mirror). As an example, in this embodiment, a fish object 17 is placed. Furthermore, the object 17 in this embodiment is placed on the concave surface of the lower concave mirror via a colored retaining member 18. In this embodiment, a colored gel-like or resin material with light transmittance is used as the retaining member 18. More specifically, the color of the retaining member 18 in this embodiment is the blue color of the sea in which the object 17, the fish, lives. As a result, the color of the retaining member 18 appears near the real image 17R of the object 17, which appears to be floating in the air, making it easier to attract the attention of people in the surrounding area.

[0043] In this embodiment, the upper concave mirror 12 is positioned opposite the concave surface of the lower concave mirror 11, with the concave surface facing downwards. An opening 13 is formed in the upper concave mirror 12 near the focal point of the lower concave mirror. When a person nearby looks into the inside of the volumatrix 10 through the opening 13, the real image 17R of the object 17 placed at the focal point of the lower concave mirror 11, and the real image 18R of the holding member 18 appear to be floating in the air near the opening 13 (see Figure 7). Note that the top and bottom of the object 17 and the top and bottom of the real image 17R are the same, but the front, back, left, and right are reversed.

[0044] As shown in Figures 1 and 6, the portion of the upper concave mirror 12 of the volmatrix 10 that is exposed to the outside is fitted with an attention indicator 14 to draw the attention of people in the vicinity to the opening 13 (i.e., the portion where the real image 17R of the object 17 is formed). Therefore, by looking at the attention indicator 14 attached to the upper concave mirror 12, people in the vicinity are more likely to focus their attention on the real image 17R of the object 17 formed in the opening 13. Thus, the attention of people in the vicinity can be drawn more strongly to the three-dimensional display object 1. In this embodiment, an arrow pointing in the direction of the opening 13 is used as the attention indicator 14. However, for example, text such as "Pay Attention Here," a picture of a person's finger pointing in the direction of the opening 13, or a change in color near the opening 13 may also be used as the attention indicator.

[0045] (3D part) Referring to Figures 1 to 4, the three-dimensional section 30 of this embodiment will be described in detail. As shown in Figures 1 to 2, the three-dimensional section 30 supports the volumatrix 10 and surrounds and shields at least a part of the lateral side of the volumatrix 10 with an information display section 60 on the outside which information is displayed. In this embodiment, the lateral side of the lower concave mirror 11 in the volumatrix 10 (which may be partially exposed) is shielded by being cylindrically surrounded by the information display section 60 provided on the three-dimensional section 30. As a result, it becomes difficult for people in the vicinity to grasp the structure of the volumatrix 10 (a structure that forms a real image 17R of the object 17 by combining the lower concave mirror 11 and the upper concave mirror 12), so they will observe the real image 17R of the object 17 with great interest. The deterioration in appearance due to the exposure of the lower concave mirror 11 is also suppressed.

[0046] Furthermore, since people in the vicinity are strongly interested in the real image 17R of the object 17 that appears to be floating, it is easy to attract the attention of those around. As a result, the information display section 60 surrounding the sides of the Volmatrix 10 also attracts the attention of those around, so by utilizing the Volmatrix 10 as a means of advertising or performance using the information display section 60, it is possible to efficiently enhance the effect of advertising or performance.

[0047] As shown in Figures 1 and 3, the outer surface of the information display unit 60 in this embodiment is adorned with information including at least one of photographs, text, and pictures (in this embodiment, photographic information), further improving the usefulness of the three-dimensional display object 1. Specifically, the information display unit 60 in this embodiment is adorned with advertising information. The real image 17R of the object 17 formed by the volmatrix 10 attracts the customer's attention to the three-dimensional display object 1, making the advertising information attached to the information display unit 60 of the three-dimensional display object 1 more easily visible to the customer. Therefore, the effectiveness of the advertising is more easily improved.

[0048] Furthermore, the vertical length (height) of the three-dimensional section 30 in this embodiment is greater than or equal to the vertical length of the lower concave mirror 11 of the volmatrix 10. More specifically, the vertical length (height) of the three-dimensional section 30 in this embodiment is greater than or equal to the vertical length of the entire volmatrix 10 (lower concave mirror 11 and upper concave mirror 12). Therefore, while attracting attention to the small real image 17R formed by the volmatrix 10, the information attached to the information display section 60 of the three-dimensional section 30 can be made to appear larger to those around it. Thus, the effects of advertising or performances using the information display section 60 become even easier to obtain.

[0049] In this embodiment, the three-dimensional section 30 supports the volmatrix 10 above the mounting surface on which the three-dimensional display object 1 is installed. As a result, compared to the case where the volmatrix 10 is placed directly on the mounting surface, the position of the real image 17R of the object 17 formed by the volmatrix 10 is also higher, making the real image 17R more noticeable. Furthermore, in this embodiment, the opening 13 of the upper concave mirror 12 (i.e., the position where the real image 17R of the object 17 is formed) is located at the very top of the three-dimensional display object 1. As a result, the real image 17R formed in the opening 13 becomes even more visible from the outside. Also, it becomes easier for people nearby to try to touch the real image 17R, thus attracting even more attention to the real image 17R.

[0050] (Configuration for arranging the information display unit) As shown in Figure 2, the three-dimensional part 30 of this embodiment comprises a base 32, a lower end mounting part 31, a light-transmitting member 40, and an internal member 50. The base 32 serves as the base that supports the entire three-dimensional display object 1. The lower end mounting part 31 is a substantially cylindrical or columnar member that extends downward from the central part of the base 32. The lower end mounting part 31 is placed on the mounting surface at the lower end of the three-dimensional display object 1. Note that in Figure 3, the lower end mounting part 31 and the base 32 of the three-dimensional part 30 are not shown. Although not shown in Figure 6, in the prototype shown in Figure 6, plates on which food and beverages are placed are used for the lower end mounting part 31 and the base 32 of the three-dimensional part 30.

[0051] The light-transmitting member 40 is made of a material that transmits light. As an example, the light-transmitting member 40 in this embodiment is made of a transparent resin. As shown in Figures 2 and 3, the light-transmitting member 40 is arranged in a cylindrical shape with an axis extending in the vertical direction, so that the inside can be seen from the outside. The light-transmitting member 40 in this embodiment is installed on the base 32.

[0052] As shown in Figures 2 to 4, the internal member 50 is positioned inside the light-transmitting member 40, with a gap G1 (in this embodiment, a cylindrical gap centered on an axis extending in the vertical direction) formed between it and the light-transmitting member 40. In this embodiment, the internal member 50 extends upward from the base 32.

[0053] As shown in Figures 2 to 4, in this embodiment, the sheet-like information display unit 60 is inserted into the gap G1 between the light-transmitting member 40 and the internal member 50, thereby positioning the information display unit 60 on the three-dimensional part 30. Therefore, since the information display unit 60 only needs to be placed in the gap G1 between the light-transmitting member 40 and the internal member 50 without using adhesive or the like, it is easy to remove the information display unit 60 from the gap G1. Consequently, workers can easily replace the information display unit 60 compared to when it is attached to the three-dimensional part 30 with seals or adhesive. Therefore, even if it is necessary to change the information on the outside of the information display unit 60, or if the information display unit 60 deteriorates or becomes soiled, workers can easily replace the information display unit 60 to address the issue.

[0054] As shown in Figures 3 and 4, in this embodiment, the gap G1 between the light-transmitting member 40 and the internal member 50 is connected in a cylindrical shape. Therefore, the worker can insert the sheet-shaped information display unit 60 at any position in the cylindrical gap G1, further improving work efficiency. However, the cylindrical gap G1 may be divided into multiple regions. Also, if the shape of the information display unit 60 is a flexible sheet, information display units 60 made of various materials can be placed in the gap G1. For example, the worker may bend an information display unit 60 made of paper, resin, or metal to match the shape of the gap G1 and then place it in the gap G1. It is also possible to place a flexible sheet-shaped display that can display various images and is deformable as the information display unit 60 in the gap G1. In this case, various information (including moving images) can be displayed on the information display unit 60.

[0055] As shown in Figure 2, in this embodiment, the internal member 50 in the three-dimensional part 30 supports the volumatrix 10. Furthermore, a gap G2 is formed between the volumatrix 10 supported by the internal member 50 and the light-transmitting member 40 which is positioned outside the internal member 50. Therefore, without removing the volumatrix 10 from the internal member 50 (i.e., while the volumatrix 10 remains supported by the internal member 50), the worker can insert the information display unit 60 into the gap G1 between the light-transmitting member 40 and the internal member 50 through the gap G2 between the volumatrix 10 and the light-transmitting member 40, and also remove the information display unit 60. Thus, work efficiency is further improved. In this embodiment, when the three-dimensional display object 1 is viewed from above, a gap G2 is formed around the entire circumference between the volumatrix 10 supported by the internal member 50 and the annular light-transmitting member 40, but a part of the volumatrix 10 and the light-transmitting member 40 may be in contact.

[0056] The method for forming a gap G2 between the volumatrix 10, supported by the internal member 50, and the light-transmitting member 40 can be appropriately selected. For example, as shown in Figure 2, the gap G2 may be formed by making the height of the upper end of the internal member 50 higher than the height of the upper end of the light-transmitting member 40. Alternatively, as shown in Figure 2, the gap G2 may be formed by making the diameter of the cylindrical light-transmitting member 40 larger than the outer diameter of the volumatrix 10 in a plan view. In the example shown in Figure 2, both of the above methods are employed, but it is also possible to employ only one of them.

[0057] As shown in Figures 2 to 4, in this embodiment, the shape of the side surface (outer surface) of the internal member 50 and the shape of the light-transmitting member 40 are both cylindrical with an axis extending in the vertical direction. The lower concave mirror 11 of the volumatrix 10 is circular when viewed from the bottom. Therefore, by making the shape of the side surface (outer surface) of the internal member 50 cylindrical (for example, forming the internal member 50 itself in a cylindrical shape as shown in Figures 2 to 4), the lower concave mirror 11 of the volumatrix 10 is more easily supported in a stable state. Also, by making the shape of the light-transmitting member 40 cylindrical, it becomes easier to make the width of the gap G1 between the internal member 50 and the light-transmitting member 40 more uniform, so that the information display unit 60 is more easily held stably. For example, by aligning the axis of the side surface of the cylindrical internal member 50 with the axis of the cylindrical light-transmitting member 40, it is possible to appropriately make the width of the gap G1 between the internal member 50 and the light-transmitting member 40 more uniform. Furthermore, by positioning the information display unit 60 in the cylindrical gap G1, the information attached to the outside of the information display unit 60 becomes easily visible from any position in the circumferential direction.

[0058] As shown in Figure 2, the volumatrix 10 of this embodiment is detachably installed on the three-dimensional part 30 (more specifically, the internal member 50 of the three-dimensional part 30) and is supported by the three-dimensional part 30. Therefore, the worker can easily separate the three-dimensional part 30 of the three-dimensional display object 1 from the volumatrix 10, making it easy to perform maintenance on the three-dimensional display object 1 (e.g., cleaning, disinfection, replacement of parts, etc.).

[0059] Furthermore, as shown in Figure 2, the three-dimensional display object 1 of this embodiment includes a fixing member 70 that fixes the volumatrix 10 to the three-dimensional part 30 (internal member 50 in this embodiment) while the volumatrix 10 is detachably installed on the three-dimensional part 30. When maintenance is performed, the fixing by the fixing member 70 is released, and the three-dimensional part 30 and the volumatrix 10 of the three-dimensional display object 1 are easily separated. Also, when the three-dimensional display object 1 is in use, the volumatrix 10 is fixed to the three-dimensional part 30, so even if someone nearby touches the three-dimensional display object 1, problems such as the volumatrix 10 falling from the three-dimensional part 30 are less likely to occur.

[0060] It is also possible to change the specific configuration of the three-dimensional section 30. For example, the shape of the internal member 50 may be a rectangular tube or the like. Similarly, the shape of the light-transmitting member 40 may also be a rectangular tube or the like. Furthermore, the internal member 50 may not be cylindrical, but rather roughly columnar (cylindrical or rectangular prism). In this case, the upper part of the columnar internal member 50 may be concave downwards. The lower concave mirror 11 of the volumatrix 10 is placed on the portion that is concave downwards, so that the volumatrix 10 is supported by the internal member 50 in a stable state. Alternatively, the internal member may be formed by arranging multiple rod-shaped members in a row. Also, instead of the internal member 50, the volumatrix 10 may be supported by other members of the three-dimensional section 30 (for example, the light-transmitting member 40). Even in this case, by removing the volumatrix 10 from the light-transmitting member 40, the worker can properly remove it from the gap G1 of the information display section 60 and insert it into the gap G1.

[0061] (Direction method) Referring to Figure 5, an example of a presentation method using the three-dimensional display 1 in this embodiment will be described. The three-dimensional display 1 in this embodiment is placed on a transport path 102 capable of transporting food and beverages, and is transported along the route of the transport path 102. In other words, a restaurant performs a presentation using the three-dimensional display 1 by placing the three-dimensional display 1 on the transport path 102 and having it transported along the route of the transport path 102.

[0062] Referring to Figure 5, an example of a restaurant transport system 100 in which a three-dimensional display object 1 is transported will be described. The restaurant transport system 100 of this embodiment includes a transport device 101. The transport device 101 transports the transported objects (plates on which food and beverages are placed, and the three-dimensional display object 1, etc.), which are objects placed on the transport path 102, along a predetermined transport direction (arrow direction in Figure 5). The transport path 102 illustrated in Figure 1 is a circulating path that runs between the kitchen K and the dining area G. The transported objects placed on the transport path 102 in the kitchen K are transported sequentially along the transport path to the vicinity of each of the multiple tables 104 (dining spaces) located in the dining area G.

[0063] According to this embodiment, the attention of customers near the transport path 102 can be strongly directed towards the three-dimensional display object 1 moving along the transport path 102. Therefore, by transporting the three-dimensional display object 1 along the transport path 102, it is possible to create an effect that attracts the attention of customers who visit the store. In addition, objects transported along the transport path 102 often rotate while moving along the transport path 102. Therefore, customers near the transport path 102 have more opportunities to see the real image 17R of the object 17 formed by the volmatrix 10 from various directions, making it easier to attract their attention more strongly. In particular, as shown in the example in Figure 5, if the transport path 102 includes a curve, the three-dimensional display object 1 is likely to rotate during transport.

[0064] In this embodiment, the outer diameter of the lower end mounting portion 31 (see Figure 2), which is placed on the transport path 102, is within ±30% (preferably ±20%) of the outer diameter of the lower end of the raised platform extending downward from the plate of the plate transported by the transport path 102. As a result, the three-dimensional display object 1 can be transported smoothly by the transport path 102, just like the plate. It is also possible to install the light-transmitting member 40 and the internal member 50 that constitute the three-dimensional portion 30 on the top of the plate on which food and beverages are placed. In other words, the base portion 32 and the lower end mounting portion 31 shown in Figure 2 may be replaced with a plate. In this case as well, the three-dimensional display object 1 can be transported smoothly by the transport path 102, just like the plate.

[0065] The technology disclosed in the above embodiments is merely an example. Therefore, it is possible to modify the technology illustrated in the above embodiments. First, it is possible to implement only a part of the technology illustrated in the above embodiments. For example, it is possible to use only the part of the three-dimensional display object 1 illustrated in the above embodiments other than the volumatrix 10 (for example, the three-dimensional part comprising the light-transmitting member 40, the internal member 50, and the information display unit 60). Even in this case, the worker can easily replace the information display unit 60 compared to when the information display unit 60 is attached to the three-dimensional part 30 by a seal or adhesive, etc. Also, the three-dimensional part 30 may support the volumatrix 10 with the lower concave mirror 11 exposed to the outside. It is also possible to configure the three-dimensional part 30 without using the information display unit 60 that surrounds and shields the sides of the lower concave mirror 11.

[0066] Furthermore, if power can be supplied to the three-dimensional display object 1 by wired power supply, wireless power supply, or batteries, etc., it is possible to add further configurations to the three-dimensional display object 1. For example, the three-dimensional display object 1 may be equipped with an object rotation unit (e.g., a motor) that rotates the object 17 installed on the volmatrix 10. In this case, the real image 17R of the object 17 formed by the volmatrix 10 also rotates, making it even easier to attract the attention of people in the surrounding area.

[0067] Furthermore, the three-dimensional display object 1 may also include an overall rotation unit (e.g., a motor) that rotates at least the information display unit 60 and the volmatrix 10 (e.g., the three-dimensional part 30 supporting the volmatrix 10) around an axis extending in the vertical direction. In this case, in addition to the real image 17R of the object 17 formed by the volmatrix 10, the information display unit 60 also rotates, making it easier to attract the attention of people in the vicinity. It is also possible to have multiple characters attached to the information display unit 60 and rotate the information display unit 60 by the overall rotation unit to allow multiple characters to be read sequentially. Furthermore, the three-dimensional display object 1 may also include an illumination light source that illuminates the object 17 placed on the volmatrix 10. In this case, the real image of the object 17 formed by the volmatrix 10 is also illuminated, making it easier to attract the attention of people in the vicinity. [Explanation of Symbols]
