Description

[Technical field]

[0001] The present disclosure relates to a projector stand and a showroom. [Background technology]

[0002] Patent Document 1 describes a projector stand. The projector stand includes a stand on the top of which a projector is placed, vertical legs that support the stand and extend vertically, horizontal legs that support the vertical legs, and casters connected to the ends of the horizontal legs. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3187562 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there are cases where many exhibits are displayed in a showroom. In particular, in such cases, when a projector stand is placed in the showroom and a projector is placed on the projector stand to project an image of the exhibit, there is a possibility that information about the exhibits may not be conveyed sufficiently to viewers of the image. In particular, when there are many exhibits in a showroom, it may be difficult to understand what the exhibits are like just by watching the image of the exhibits.

[0005] For example, it is conceivable to arrange an exhibit in the showroom that is the same as the exhibit displayed by the projector. However, if an exhibit in the showroom is arranged that is the same as the exhibit displayed by the projector, it is expected that a large space cannot be secured in the showroom.

[0006] An object of the present disclosure is to provide a projector stand and a showroom that can adequately convey information about exhibits to people and ensure ample space in the showroom. [Means for solving the problem]

[0007] The projector stand according to the present disclosure is (1) a projector stand on which a projector that projects an exhibit by an image is placed. The projector stand includes a first placement section extending in both a first direction and a second direction intersecting with the first direction and on which the projector is placed, a top plate that is separated from the first placement section in a third direction intersecting with both the first and second directions and extends in both the first and second directions, and a side wall that connects the first placement section to the top plate and is provided so as to surround the first placement section. The top plate has a first opening that penetrates the top plate in the third direction and through which light from the projector passes. The top plate protrudes from the outer periphery of the side wall when viewed from the third direction and has an exhibit placement section on which an exhibit projected by the projector is placed.

[0008] In this projector stand, the top plate has a first opening penetrating the top plate in the third direction and through which the light from the projector passes. Thus, by guiding the light projected by the projector to the first opening, the light can be projected outside the projector stand. This allows the image by the projector to be projected onto a wall of the showroom located outside the projector stand, a screen, or the like. The top plate protrudes from the outer periphery of the side wall when viewed from the third direction, and has an exhibit placement section on which the exhibit projected by the projector is placed. Thus, the same exhibit as the exhibit projected as the image can be placed on the exhibit placement section protruding from the outer periphery of the side wall when viewed from the third direction. As a result, the information about the exhibit can be sufficiently conveyed to people by showing the image and the actual exhibit. Furthermore, since the exhibit only needs to be placed on the exhibit placement section of the projector stand, the arrangement space for the actual exhibit in the showroom can be reduced. Therefore, a large space can be secured in the showroom.

[0009] (2) The projector stand of (1) above may further include a second mounting section on which a motion sensor is mounted, the motion sensor extending in both the first and second directions below the top plate and detecting a person approaching the projector stand. The projector may project an exhibit as an image when the motion sensor detects a person. The top plate may have a second opening penetrating the top plate in a third direction and exposing the motion sensor. In this case, the motion sensor mounted on the second mounting section is exposed from the second opening of the top plate, so that the motion sensor can detect a person located outside the projector stand through the second opening. In addition, the projector projects an exhibit as an image when the motion sensor detects a person. This allows, for example, a person to hold their hand over the second opening to start projecting an image by the projector.

[0010] (3) The projector stand of (1) or (2) above may include a movement restricting portion that is fixed to the first mounting portion and restricts the movement of the projector mounted on the first mounting portion in the first direction. In this case, the movement of the projector mounted on the first mounting portion in the first direction can be restricted by the movement restricting portion. This makes it possible to stabilize the position of the projector on the first mounting portion. As a result, the light projected by the projector mounted on the first mounting portion can be easily and appropriately guided to the first opening, making it possible to more stably project an attractive image.

[0011] The showroom according to the present disclosure is (4) a showroom in which any of the projector stands (1) to (3) above is arranged. This showroom includes a projector stand having an exhibit placement part whose top plate protrudes from the outer contour of a side wall when viewed from a third direction, and another projector stand different from the projector stand, which has a first placement part, a top plate different from the above top plate, and a side wall, and the other top plate does not have an exhibit placement part.

[0012] The showroom includes a projector stand having an exhibit placement section whose top plate protrudes from the outer periphery of the side wall when viewed from the third direction. Thus, by placing an exhibit on the exhibit placement section, the viewer's understanding of the exhibit projected by the projector is deepened. The showroom further includes another projector stand having a top plate that does not have an exhibit placement section. The other projector stand having a top plate that does not have an exhibit placement section is smaller than the projector stand having a top plate that has an exhibit placement section. For example, if an exhibit is not projected in the image projected by the projector placed on the first placement section of the other projector stand, there is no need to place an exhibit on the top plate. In such a case, by installing the other projector stand having a top plate that does not have an exhibit placement section in the showroom, the space of the showroom can be further saved. Therefore, a projector stand having a top plate with an exhibit placement portion and another projector stand having a top plate without an exhibit placement portion can be used depending on the content of the image to be projected. Effect of the Invention

[0013] According to the present disclosure, it is possible to provide a projector stand and a showroom that can adequately convey information about exhibits to people and ensure ample space in the showroom. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of a projector stand and a showroom according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.

[0016] FIG. 1 is a plan view of the showroom 100. FIG. 2 is an enlarged perspective view of a part of the showroom 100. The showroom 100 is, for example, a space for introducing a company. Examples of the introduction of a company include an introduction of the company's history, an introduction of products sold by the company, and an introduction of goods of a person (e.g., an athlete) sponsored by the company. The showroom 100 is a rectangular parallelepiped space. The showroom 100 has a floor 100a, an outer wall 100b arranged to surround the floor 100a, a ceiling (not shown) arranged to face the floor 100a, and an entrance / exit 100c for entering and exiting the showroom 100. The showroom 100 extends in both the longitudinal direction Da and the transverse direction Db intersecting with the longitudinal direction Da in a plan view. The entrance / exit 100c is provided in a portion of the outer wall 100b extending in the transverse direction Db.

[0017] The showroom 100 includes a first projector stand 1 (projector stand) on which a projector P that projects images of exhibits is placed, a second projector stand 101 (another projector stand) on which the projector P is placed, and screens 105, 106, 107, and 108 onto which at least one of the first projector stand 1 and the second projector stand 101 projects images.

[0018] For example, the screen 105 has a plate shape. The screen 105 may be a wall. The color of the screen 105 is, for example, white. The same is true for each of the screens 106, 107, and 108. The first projector stand 1 and the second projector stand 101 are disposed inside the showroom 100. A detailed description of the first projector stand 1 and the second projector stand 101 will be given later.

[0019] The screens 105, 106, 107, and 108 are arranged on the floor 100a so as to have, for example, a U-shape (or a C-shape) in a plan view. More specifically, the screen 106 is arranged so as to extend in the short direction Db and to face the entrance 100c. The screen 105 is arranged so as to extend in the longitudinal direction Da. The screen 105 is arranged between the entrance 100c and the screen 106. Each of the screens 107 and 108 extends in the longitudinal direction Da. The screens 107 and 108 are lined up along the longitudinal direction Da. The entrance 100c, the screen 108, the screen 107, and the screen 106 are lined up in this order along the longitudinal direction Da.

[0020] The screens 107 and 108 are arranged to face the screen 105. When viewed from the direction from the screen 106 toward the entrance 100c, the screen 105 is arranged to the right of the entrance 100c, and the screens 107 and 108 are arranged to the left of the entrance 100c. In the short direction Db, the distance from the screen 107 to the entrance 100c is longer than the distance from the screen 108 to the entrance 100c. The screens 105, 106, 107, and 108 are arranged in a state of being spaced apart from each other. The display area R1 is provided in the area surrounded by the screens 105, 106, 107, and 108. In this specification, the side of the screens 105, 106, 107, and 108 toward the display area R1 is referred to as the "inside", and the opposite side to the inside is referred to as the "outside".

[0021] In the exhibition area R1, a first projector stand 1 and a second projector stand 101 are arranged in a position facing (or in contact with) the screen 105. The first projector stand 1 and the second projector stand 101 are arranged on the floor 100a. More specifically, one first projector stand 1 and a plurality of (for example, three) second projector stands 101 are arranged to be lined up along the longitudinal direction Da. For example, the first projector stand 1 and the second projector stand 101 may be arranged to be lined up alternately. In the example of FIG. 1, the first projector stand 1 and the second projector stand 101 are arranged to be lined up from the entrance 100c toward the screen 106. For example, the second projector stand 101, the second projector stand 101, the first projector stand 1, and the second projector stand 101 are arranged to be lined up in this order.

[0022] Of the multiple second projector stands 101 facing the screen 105, the projector P installed on the second projector stand 101 closest to the entrance 100c projects, for example, an image relating to the history of the company. The projector P installed on the second projector stand 101 adjacent to the second projector stand 101 projects, for example, an image relating to another part of the company's history. The projector P installed on the first projector stand 1 facing the screen 105 projects, for example, an image relating to an exhibit.

[0023] An "exhibit" refers to an item that is shown to people in a showroom. An "exhibit" is, for example, displayed as an actual product or a sample of a product for sale. As an example, an "exhibit" is a new product. In this way, an "exhibit" may or may not be a product (it may simply be something displayed in a show window, etc.). An "exhibit" is, for example, bedding. However, an "exhibit" may also be small items, ornaments, leather products, watches, jewelry, stationery, cosmetics, or food and beverages such as sweets.

[0024] Of the multiple second projector stands 101 facing the screen 105, the projector P installed on the second projector stand 101 closest to the screen 106 projects, for example, an image relating to a company's efforts toward the SDGs (Sustainable Development Goals).

[0025] In exhibition area R1, second projector stand 101 is disposed in a position facing screen 106. In exhibition area R1, second projector stand 101 is disposed in a position facing screen 107. In exhibition area R1, first projector stand 1 is disposed in a position facing screen 108.

[0026] The projector P installed on the second projector stand 101 facing the screen 106 projects, for example, an image related to a company's efforts in IoT (Internet of Things). The projector P installed on the second projector stand 101 facing the screen 107 projects, for example, an image related to an advertisement featuring a person (e.g., an athlete) sponsored by the company. The projector P installed on the first projector stand 1 facing the screen 108 projects, for example, an image related to Beauty Sleep (registered trademark). In this case, the projector P installed on the first projector stand 1 facing the screen 108 projects an image introducing a method for improving the quality of a sleep cycle in a certain time (e.g., 90 minutes) after a person falls asleep.

[0027] The showroom 100 has exhibition stands 102, 103, and 104 in the exhibition area R1. The exhibition stands 102, 103, and 104 are arranged on a floor 100a. The exhibition stand 102 is arranged between a screen 106 and a screen 107. The exhibition stand 102 has a rectangular shape in a plan view. The length of the exhibition stand 102 in the longitudinal direction Da is longer than the length of the exhibition stand 102 in the lateral direction Db.

[0028] The showroom 100 has a curtain 109 extending along the screen 107 on the outside of the screen 107. The curtain 109 extends so as to protrude from both sides of the screen 107 in the longitudinal direction Da, for example. The exhibition stand 102 is in contact with the curtain 109, for example. Exhibits are displayed on the exhibition stand 102. For example, items related to people sponsored by a company are displayed on the exhibition stand 102. For example, uniforms of athletes are displayed on the exhibition stand 102.

[0029] Lighting and a motion sensor are installed on the ceiling of the showroom 100 in a portion that overlaps in plan view with the position where the exhibition stand 102 is located. When this motion sensor detects a person approaching the exhibition stand 102, the lighting installed in that portion of the ceiling is turned on. This lighting is turned off after the motion sensor continues to detect no person for a predetermined period of time (e.g., several minutes) with the lighting on. Note that part of the motion sensor installed on the ceiling may be blocked so that the sensitivity is not too high.

[0030] The exhibition stand 103 is disposed between the screen 105 and the screen 106. The exhibition stand 103 has a rectangular shape in a plan view. The length of the exhibition stand 103 in the longitudinal direction Da is substantially the same as the length of the exhibition stand 103 in the lateral direction Db. An exhibit is exhibited on the exhibition stand 103. For example, an exhibit introduced in a video projected by the second projector stand 101 facing the screen 105 is exhibited on the exhibition stand 103. In this embodiment, the exhibit introduced in a video projected by the second projector stand 101 closest to the exhibition stand 103 among the multiple second projector stands 101 facing the screen 105 is exhibited on the exhibition stand 103. For example, the exhibit may be made of the same material as that introduced in a video related to a company's efforts toward the SDGs.

[0031] The exhibition stand 104 is disposed between the first projector stand 1 facing the screen 108 and an outer wall 100b in which an entrance 100c is provided. The exhibition stand 104 has a rectangular shape in a plan view. The four sides forming the exhibition stand 104 in a plan view extend in a direction inclined with respect to both the longitudinal direction Da and the lateral direction Db. Exhibits are displayed on the exhibition stand 104. For example, sleep aids are displayed on the exhibition stand 104. Sleep aids are products that help people fall asleep.

[0032] A stock area R2 is provided outside the screen 106. In other words, the stock area R2 and the exhibition area R1 are separated by the screen 106. In the stock area R2, for example, the exhibits exhibited on the exhibition stands 102, 103, and 104, as well as spare parts for the exhibits introduced in the images projected by the first projector stand 1 and the second projector stand 101 are stored.

[0033] A plurality of lights are fixed to the ceiling of the showroom 100 to illuminate the exhibition area R1. The lights are arranged, for example, along the longitudinal direction Da. The lights are, for example, ceiling spotlights. In this case, the lights can brighten a specific position in the showroom 100 with pinpoint accuracy, for example, to highlight an exhibit. For example, a lighting adjustment area R3 for adjusting the brightness of the lights is provided on the outside of the screen 108.

[0034] For example, the lighting control area R3 and the exhibition area R1 are separated by a screen 108. A switch 110 is arranged in the lighting control area R3. By operating the switch 110, the lighting pattern by the above-mentioned multiple lights can be changed. The switch 110 has, for example, multiple switch bodies to be operated and a switch panel to which the multiple switch bodies are attached. By operating the multiple switch bodies, various lighting patterns are realized.

[0035] Next, the first projector stand 1 will be described in detail with reference to Figs. 3 to 6. Fig. 3 is a plan view of the first projector stand 1. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a cross-sectional view taken along line VV in Fig. 3. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 3. As shown in Fig. 3, the first projector stand 1 has a rectangular parallelepiped shape. The first projector stand 1 has a rectangular shape in plan view.

[0036] Hereinafter, the longitudinal direction of the first projector stand 1 in plan view is referred to as the first direction D1, the lateral direction of the first projector stand 1 in plan view is referred to as the second direction D2, and the height direction of the first projector stand 1 is referred to as the third direction D3. The second direction D2 intersects with the first direction D1. The third direction D3 intersects with both the first direction D1 and the second direction D2. For example, the first direction D1 is a horizontal direction from the first projector stand 1 toward the screen 105, and the second direction D2 is a horizontal direction perpendicular to the first direction D1. For example, the third direction D3 is vertically upward.

[0037] When the first projector stand 1 faces the screen 105, the direction when the screen 105 is viewed from the first projector stand 1 is referred to as the "rear", "rear side" or "rear", and the direction when the first projector stand 1 is viewed from the screen 105 is referred to as the "front", "front side" or "forward". However, these directions are for convenience of explanation and do not limit the arrangement position or direction of objects.

[0038] 3 and 4, the first projector stand 1 includes a bottom plate 2 constituting the bottom of the first projector stand 1, a side wall 3 provided to surround the bottom plate 2, a first mounting portion 4 on which the projector P is placed, a second mounting portion 5 on which a human sensor S for detecting a person approaching the first projector stand 1 is placed, and a top plate 6 constituting the upper portion of the first projector stand 1. As described later, for example, at least a part of the first projector stand 1 is made of melamine (melamine resin). In this case, the first projector stand 1 can be made scratch-resistant and highly weather-resistant.

[0039] The bottom plate 2 extends in both the first direction D1 and the second direction D2. The bottom plate 2 is a plate-like member having a thickness in the third direction D3. For example, the bottom plate 2 has a rectangular shape. The bottom plate 2 is made of, for example, melamine. The bottom plate 2 is disposed apart from a surface (floor 100a in this embodiment) on which the first projector stand 1 is placed. In other words, the bottom plate 2 is located vertically above the floor 100a.

[0040] The first projector stand 1 includes, for example, casters 7 provided on the lower part of the bottom plate 2, and legs 8 provided on the lower part of the bottom plate 2 at positions different from the casters 7. The first projector stand 1 includes a plurality of casters 7. As an example, the casters 7 are provided near each of the four corners of the bottom plate 2. The casters 7 include wheels 7a that allow the first projector stand 1 to move, and mounting parts 7b that support the wheels 7a rotatably around an axis extending in the third direction D3. The mounting parts 7b support the wheels 7a rotatably, so that the rotation axis of the wheels 7a rotates around the axis. This allows the first projector stand 1 to move in a desired direction along a surface extending in both the first direction D1 and the second direction D2.

[0041] The legs 8 are parts that support the first projector stand 1. The length of the legs 8 in the third direction D3 is adjustable. The length of the legs 8 in the third direction D3 is adjustable, for example, by rotating the legs 8 around the third direction D3. The legs 8 are composed of a screw tube and a screw, and the length of the legs 8 in the third direction D3 is adjustable by rotating the screw relative to the screw tube. The first projector stand 1 has, for example, a plurality of legs 8 (four legs, for example). For example, each of the plurality of legs 8 is disposed outside the caster 7 in the first direction D1 and the second direction D2. That is, the legs 8 are disposed closer to the corners of the bottom plate 2 in plan view than the caster 7. By adjusting the length of each of the plurality of legs 8 in the third direction D3, the top plate 6 of the first projector stand 1 can be tilted. That is, the central axis AX that passes through the center of the bottom plate 2 in plan view and extends along the vertical direction can be tilted to a desired angle with respect to the vertical direction.

[0042] The side wall 3 extends in the third direction D3. More specifically, the side wall 3 includes a front wall 3a extending in the second direction D2 and the third direction D3 at a front end of the bottom plate 2, a rear wall 3b extending in the second direction D2 and the third direction D3 at a rear end of the bottom plate 2, and a pair of lateral walls 3e extending in the first direction D1 and the third direction D3 at both ends of the bottom plate 2 in the second direction D2.

[0043] For example, the side wall 3 has a rectangular frame shape in a plan view. The side wall 3 is provided so as to surround the first mounting portion 4 and the second mounting portion 5 in a plan view. The side wall 3 connects the bottom plate 2, the first mounting portion 4, the second mounting portion 5, and the top plate 6 to one another. The side wall 3 connects the first mounting portion 4 to the top plate 6. That is, the first mounting portion 4 and the top plate 6 are connected to the inside of the side wall 3 in a plan view, and the top plate 6 is located vertically above the first mounting portion 4.

[0044] The side wall 3 defines an internal space of the first projector stand 1, which has, for example, a frame shape in a plan view. The lower end of the side wall 3 is located below the bottom plate 2 and above the lower ends of the casters 7. The front wall 3a of the side wall 3 is connected to the front end of the bottom plate 2, and the rear wall 3b is connected to the rear end of the bottom plate 2. Each of the pair of lateral walls 3e connects the front wall 3a to the rear wall 3b.

[0045] The side wall 3 has a speaker net 3c provided on the front wall 3a. The speaker net 3c is in a mesh shape. The speaker net 3c is provided to pass the sound output from the speaker of the projector P to the outside of the first projector stand 1. The speaker net 3c is arranged between the first mounting part 4 and the second mounting part 5 in the third direction D3. The area between the first mounting part 4 and the second mounting part 5 in the third direction D3 of the first projector stand 1 is the area where the projector P is arranged. Therefore, when the speaker net 3c is arranged between the first mounting part 4 and the second mounting part 5 in the third direction D3, the sound from the projector P can be efficiently output to the outside of the first projector stand 1.

[0046] The side wall 3 has a rear wall opening 3d provided in the rear wall 3b. The rear wall opening 3d has, for example, a rectangular shape. The rear wall opening 3d is provided in, for example, a lower portion of the rear wall 3b. In this case, wiring and the like can be easily inserted and removed through the rear wall opening 3d. The internal space of the first projector stand 1 can be accessed through the rear wall opening 3d. A power cable M3a extending from a receptacle M3 (described later) can be pulled out to the outside of the first projector stand 1 through the rear wall opening 3d, and the power cable M3a can be connected to a receptacle outside the first projector stand 1.

[0047] The first mounting portion 4 extends in both the first direction D1 and the second direction D2, and has a thickness in the third direction D3. The first mounting portion 4 is, for example, plate-shaped. The length of the first mounting portion 4 in the first direction D1 is shorter than the length of the bottom plate 2 in the first direction D1. The first mounting portion 4 is, for example, fixed to the front wall 3a in a state of contact with the front wall 3a. The first projector stand 1 has a gap 1a provided between the first mounting portion 4 and the rear wall 3b.

[0048] For example, a power cable P4 and a transmission cable P5 extend from the projector P. The power cable P4 and the transmission cable P5 extending from the projector P extend through the gap 1a to a region below the first mounting portion 4 in the internal space of the first projector stand 1. The first mounting portion 4 is located vertically above the bottom plate 2. The first mounting portion 4 is disposed at a distance from the bottom plate 2 in the third direction D3. The first mounting portion 4 is made of, for example, melamine.

[0049] The projector P is placed on the first placement portion 4. For example, the projector P is placed on the first placement portion 4 so that the longitudinal direction of the projector P is aligned along the first direction D1 and the lateral direction of the projector P is aligned along the second direction D2. The projector P has a main body P1, a projection portion P2, legs P3, a power cable P4 that supplies power to the internal devices of the main body P1, and a transmission cable P5 that transmits video signals and audio signals to the internal devices of the main body P1.

[0050] The main body P1 includes a housing of the projector P and devices inside the housing. The projection unit P2 has an exit port from which light is projected. The projection unit P2 is disposed, for example, on the upper surface of the main body P1. The leg P3 is disposed on the lower part of the main body P1. The projector P has, for example, a plurality of legs P3 (four legs, for example). For example, two legs P3 are aligned along the first direction D1, and two legs P3 other than the two legs P3 are aligned along the first direction D1 at a position spaced apart from the two legs P3 in the second direction D2. The power cable P4 and the transmission cable P5 are connected, for example, to the rear end of the main body P1.

[0051] The first placement portion 4 has a movement restriction portion 4a that restricts the movement of the projector P in the first direction D1. The movement restriction portion 4a protrudes upward from the upper surface of the first placement portion 4, for example. The movement restriction portion 4a may be a separate body from the first placement portion 4. In this case, the movement restriction portion 4a may be fixed to the upper surface of the first placement portion 4. The movement restriction portion 4a extends linearly in the second direction D2. The length (thickness) of the movement restriction portion 4a in the third direction D3 is shorter than the separation distance between the lower surface of the main body portion P1 of the projector P and the first placement portion 4. That is, the length of the movement restriction portion 4a in the third direction D3 is shorter than the length of the leg P3 in the third direction D3. The movement restriction portion 4a is located on the lower side of the main body portion P1, and the projector P is disposed so that the movement restriction portion 4a faces the leg P3 in the first direction D1, thereby restricting the movement of the projector P in the first direction D1.

[0052] The second mounting portion 5 extends in both the first direction D1 and the second direction D2, and has a thickness in the third direction D3. The second mounting portion 5 is, for example, plate-shaped. For example, the length of the second mounting portion 5 in the first direction D1 is the same as the length of the bottom plate 2 in the first direction D1. For example, the length of the second mounting portion 5 in the second direction D2 is the same as the length of the bottom plate 2 in the second direction D2. In this case, the second mounting portion 5 overlaps the bottom plate 2 in a plan view.

[0053] As shown in Figs. 4, 5 and 6, the second placement portion 5 has an opening 5a extending in the first direction D1 and the second direction D2 and penetrating the second placement portion 5 in the third direction D3. For example, the length of the opening 5a in the first direction D1 is longer than the length of the projector P in the first direction D1. For example, the length of the opening 5a in the second direction D2 is longer than the length of the projector P in the second direction D2. A part of the projector P protrudes upward beyond the second placement portion 5 through the opening 5a. The second placement portion 5 is made of, for example, melamine.

[0054] The second placement portion 5 has an extending portion 5b located forward of the opening 5a. The extending portion 5b extends in both the first direction D1 and the second direction D2 between the pair of side walls 3e. A human presence sensor S is placed on the extending portion 5b. The human presence sensor S detects a person approaching the first projector stand 1. More specifically, the human presence sensor S detects an object located above the human presence sensor S.

[0055] The human sensor S has a main body S1 having a functional part for detecting an object, and a transmission cable S2 extending from the main body S1. The main body S1 has, for example, a rectangular parallelepiped shape. When a person is detected by the main body S1, the transmission cable S2 transmits a signal associated with the detection. The first mounting part 4 has an opening 4b that overlaps at least a part of the opening 5a in a plan view. The opening 4b penetrates the first mounting part 4 in the third direction D3. For example, the front end of the opening 5a and the opening 4b are aligned along the third direction D3. The transmission cable S2 extends, for example, from the rear end of the main body S1. The transmission cable S2 extends through the opening 4b to a region below the first mounting part 4 in the internal space of the first projector stand 1.

[0056] The top plate 6 extends in both the first direction D1 and the second direction D2. The top plate 6 is, for example, plate-like with a thickness in the third direction D3. For example, the length of the top plate 6 in the first direction D1 is longer than the length of the top plate 6 in the second direction D2. Both ends of the top plate 6 in the second direction D2 are located above the pair of side walls 3e. In the first direction D1, the position of the rear end of the top plate 6 is, for example, the same as the position of the outer surface of the rear wall 3b.

[0057] The position of the front end of the top plate 6 is located forward of the position of the outer surface of the front wall 3a. The top plate 6 is separated from the first mounting portion 4 in the third direction D3. The top plate 6 is separated from the second mounting portion 5 in the third direction D3. The second mounting portion 5 is located between the first mounting portion 4 and the top plate 6. The second mounting portion 5 is located below the top plate 6. The top plate 6 is made of, for example, melamine.

[0058] The top plate 6 has an exhibit placement section 6a protruding from the outer periphery of the side wall 3 when viewed from the third direction D3, and a top surface section 6b surrounded by the outer periphery of the side wall 3 when viewed from the third direction D3. An exhibit projected by the projector P is placed on the exhibit placement section 6a. The top plate 6 has a first opening 6c through which light from the projector P passes, and a second opening 6d through which the human sensor S is exposed. The first opening 6c and the second opening 6d are provided on the top surface section 6b. The first opening 6c and the second opening 6d penetrate the top plate 6 in the third direction D3.

[0059] 3, 4 and 6, the first opening 6c has, for example, a rectangular shape. The length of the first opening 6c in the first direction D1 is longer than the length of the projection unit P2 of the projector P in the first direction D1 and shorter than the length of the main body P1 of the projector P in the first direction D1. The length of the first opening 6c in the second direction D2 is equal to, for example, the length of the bottom plate 2 in the second direction D2. The second opening 6d is disposed near the end of the first opening 6c in the second direction D2.

[0060] The second opening 6d is larger than the human sensor S in a plan view. That is, the area of ​​the second opening 6d in a plan view is larger than the area of ​​the human sensor S in a plan view. The second opening 6d and the human sensor S are aligned along the third direction D3. As described above, the human sensor S is exposed in the second opening 6d. "The human sensor is exposed" includes both a case where the human sensor protrudes from an object and is visible, and a case where the human sensor does not protrude from an object but is visible by looking into the opening. In this embodiment, the human sensor S does not protrude from the top plate 6, but is visible by looking into the second opening 6d.

[0061] Inside the first projector stand 1, for example, a video player M1, a sensor connector M2 that receives a signal from a human sensor S, and a socket M3 are arranged. The video player M1 is a device that stores video and audio. A transmission cable P5 is connected to the video player M1. The video player M1 transmits the stored video and audio via the transmission cable P5.

[0062] The video player M1 has, for example, a power cable M1a extending from a location different from the transmission cable P5. The power cable M1a is connected to an outlet M3 and receives power from the outlet M3. The power cable M1a supplies the power supplied from the outlet M3 to the video player M1 (for example, an internal device of the video player M1). A signal is transmitted to the video player M1 from the sensor connector M2. When the video player M1 receives the signal from the sensor connector M2, it transmits the video signal and the audio signal to the projector P.

[0063] When the sensor connector M2 receives a signal transmitted from the human presence sensor S, it transmits the signal to the video player M1. For example, a power cable M2a and a signal transmission cable M2b are connected to the sensor connector M2. The power cable M2a supplies power supplied from the outlet M3 to the sensor connector M2. The signal transmission cable M2b is connected to the video player M1. The sensor connector M2 transmits a signal to the video player M1 via the signal transmission cable M2b.

[0064] The outlet M3 supplies power to each of the projector P and the video player M1. A power cable P4 extending from the projector P, a power cable M1a extending from the video player M1, and a power cable M2a extending from the sensor connector M2 are connected to the outlet M3. The outlet M3 is provided, for example, at the tip of a power cable M3a that transmits power from a commercial power source. Power is supplied to the outlet M3 from a commercial power source external to the first projector stand 1 via the power cable M3a.

[0065] Next, the operation of each component when a person approaching the first projector stand 1 is detected and the projector P projects an image will be described. First, a person approaches the first projector stand 1 and holds his / her hand over the second opening 6d. When the hand is held over the second opening 6d, the human sensor S detects the hand. The human sensor S detects the hand and transmits a signal to the sensor connector M2 via the transmission cable S2. When the sensor connector M2 receives a signal transmitted from the human sensor S, it transmits the signal to the video player M1 via the signal transmission cable M2b. When the video player M1 receives a signal from the sensor connector M2, it transmits the video signal and the audio signal to the projector P via the transmission cable P5. When the projector P receives the video signal and the audio signal transmitted from the video player M1, it emits light from the projection unit P2 to the screen 105 or the like and outputs audio from the speaker. In this way, when the motion sensor S detects a person, the projector P projects the exhibit as an image on the screen 105 or the like, and outputs, for example, a sound related to an explanation of the exhibit from the speaker.

[0066] Next, the second projector stand 101 will be described in detail. The second projector stand 101 differs from the first projector stand 1 in that the second projector stand 101 has a top plate that does not have an exhibit placement section 6a, instead of the top plate 6. For example, the configuration of the second projector stand 101 other than the top plate is the same as the configuration of the first projector stand 1. Therefore, a detailed description of the second projector stand 101 will be omitted. In the second projector stand 101, a projector P, a human sensor S, a video player M1, a sensor connector M2, and a socket M3 are arranged, similarly to the first projector stand 1.

[0067] Next, the effects of the first projector stand 1 and the showroom 100 of this embodiment will be described. In the first projector stand 1, the top plate 6 has a first opening 6c that penetrates the top plate 6 in the third direction D3 and through which light from the projector P passes. Therefore, by guiding the light projected by the projector P to the first opening 6c, the light can be projected outside the first projector stand 1. This allows an image by the projector P to be projected onto the outer wall 100b of the showroom 100 located outside the first projector stand 1, or onto screens 105-108, etc.

[0068] The top plate 6 protrudes from the outer periphery of the side wall 3 when viewed from the third direction D3, and has an exhibit placement section 6a on which the exhibit projected by the projector P is placed. Therefore, an exhibit identical to the exhibit projected as an image can be placed on the exhibit placement section 6a protruding from the outer periphery of the side wall 3 when viewed from the third direction D3. As a result, information about the exhibit can be conveyed to people sufficiently by showing the image of the exhibit and the actual item. Furthermore, since the exhibit only needs to be placed on the exhibit placement section 6a of the first projector stand 1, the space required for arranging the actual exhibit in the showroom 100 can be reduced. Therefore, a large space can be secured in the showroom 100.

[0069] The first projector stand 1 includes a second mounting portion 5 that extends in both the first direction D1 and the second direction D2 under the top plate 6 and on which a human sensor S is mounted to detect a person approaching the first projector stand 1. The projector P projects an exhibit as an image when the human sensor S detects a person. The top plate 6 has a second opening 6d that penetrates the top plate 6 in the third direction D3 and exposes the human sensor S. In this case, the human sensor S mounted on the second mounting portion 5 is exposed from the second opening 6d of the top plate 6, so that the human sensor S can detect a person located outside the first projector stand 1 through the second opening 6d. In addition, the projector P projects an exhibit as an image when the human sensor S detects a person. This allows, for example, a person to hold their hand over the second opening 6d to start projecting an image by the projector P.

[0070] The first projector stand 1 is fixed to the first mounting portion 4 and includes a movement restricting portion 4a that restricts the movement of the projector P placed on the first mounting portion 4 in the first direction D1. In this case, the movement of the projector P placed on the first mounting portion 4 in the first direction D1 can be restricted by the movement restricting portion 4a. This allows the position of the projector P on the first mounting portion 4 to be stabilized. As a result, the light projected by the projector P placed on the first mounting portion 4 can be easily and appropriately guided to the first opening 6c, so that an image that attracts people can be projected more stably. The first projector stand 1 may be fixed to the first mounting portion 4 and includes a movement restricting portion that restricts the movement of the projector P placed on the first mounting portion 4 in the second direction D2. In this case, the same effect as above can be obtained.

[0071] The showroom 100 includes a first projector stand 1 having an exhibit placement portion 6a whose top plate 6 protrudes from the outer periphery of the side wall 3 when viewed from the third direction D3. Thus, by placing an exhibit on the exhibit placement portion 6a, the viewer's understanding of the exhibit projected by the projector P is deepened. The showroom 100 further includes a second projector stand 101 having a top plate without an exhibit placement portion 6a. The second projector stand 101 having a top plate without an exhibit placement portion 6a is smaller than the first projector stand 1 having a top plate 6 with an exhibit placement portion 6a. In this embodiment, the second projector stand 101 having no exhibit placement portion 6a has a rectangular parallelepiped shape. Thus, the second projector stand 101 is even more compact than the first projector stand 1.

[0072] For example, if the image projected by the projector P placed on the first mounting portion 4 of the second projector stand 101 does not include an exhibit, there is no need to mount an exhibit on the top plate 6. In this embodiment, the projector P placed on the second projector stand 101 displays an image of the company's history or an image of the company's efforts, so no space is required to mount an exhibit. In such a case, by installing a compact second projector stand 101 with a top plate that does not have an exhibit mounting portion 6a in the showroom 100, the space of the showroom 100 can be further saved. Therefore, the first projector stand 1 with the top plate 6 with the exhibit mounting portion 6a and the second projector stand 101 with a top plate that does not have the exhibit mounting portion 6a can be used depending on the content of the image to be projected.

[0073] The above describes the embodiments of the projector stand and showroom according to the present disclosure. However, the present invention is not limited to the above-described embodiments, and may be modified or applied to other things without changing the gist of the claims. In other words, the shape, size, material, number, and arrangement of each part of the projector stand and showroom according to the present disclosure can be modified in various ways without changing the gist of the claims.

[0074] For example, the first projector stand 1 may be provided with a heat exhaust fan disposed adjacent to the projector P. By operating the heat exhaust fan, the heat radiated by the projector P can be exhausted to the outside of the first projector stand 1. Also, an exhaust port may be formed in the region between the first placement part 4 and the second placement part 5 in the third direction D3 of the side wall 3. In this case as well, the same effect as above can be obtained. [Explanation of symbols]
