Summary of Invention

Problem to be Solved by the Invention

[0004] However, in the conventional low-ceiling storage room, it was necessary to move while bending when entering the interior of the low-ceiling storage room from the entrance, so stored items stored in the deep part of the low-ceiling storage room tended to be difficult to take out, and as a result, the frequency of use tended to decrease. In particular, when storing food, there is a possibility that the best-before date will expire if the food is not properly managed. In addition, since stored items tend to concentrate near the entrance, there has also been a problem that the deep part of the low-ceiling storage room cannot be fully utilized.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to improve the ease of taking out stored items in a low-ceiling storage room and to enable the entire storage space to be effectively utilized.

Means for Solving the Problem

[0006] The invention described in claim 1 relates to a building 100,200 comprising, for example, as shown in Figures 1 to 6, a low-ceiling storage room 101,201 surrounded by four walls 106,206 and with a ceiling height set to 0.8m to 1.4m, and adjacent rooms 104,204 located adjacent to the low-ceiling storage rooms 101,201, The four walls 106,206 are: Located between the low-ceiling storage rooms 101, 201 and the adjacent rooms 104, 204, the first walls 106a, 206a have openings 107, 207 formed therein, The first walls 106a, 206a and the second walls 106b, 206b directly opposite each other are included. The low-ceiling storage rooms 101 and 201 are characterized in that they are equipped with storage devices 110 and 210 configured to allow the storage items 1 to be transported by circulating them between the first walls 106a and 206a and the second walls 106b and 206b while the storage items 1 are placed on them.

[0007] According to the invention described in claim 1, the four walls 106,206 surrounding the low-ceiling storage rooms 101,201 include first walls 106a,206a located between the low-ceiling storage rooms 101,201 and the adjacent rooms 104,204, with openings 107,207 formed therein, and second walls 106b,206b directly opposite the first walls 106a,206a. The low-ceiling storage rooms 101,201 are equipped with storage devices 110,210 configured to allow the storage items 1 to be transported by circulating them between the first walls 106a,206a and the second walls 106b,206b while the storage items 1 are placed inside. Therefore, the storage items 1 can be moved in and out of the storage devices 110,210 through the openings 107,207 in the first walls 106a,206a. Then, with the stored item 1 placed on it, if the stored item 1 is transported to the back second wall 106b, 206b side by the storage devices 110, 210, the stored item 1 can be stored at the back of the low-ceiling storage room 101, 201. Furthermore, when retrieving the stored item 1 stored at the back of the low-ceiling storage room 101, 201, if the stored item 1 is transported to the front first wall 106a, 206a side by the storage devices 110, 210, the stored item 1 can be easily retrieved from the opening 107, 207. This improves the ease of retrieving the stored item 1 from the low-ceiling storage room 101, 201 and makes effective use of the entire storage space of the low-ceiling storage room 101, 201.

[0008] The invention described in claim 2 is, for example, as shown in Figures 1 to 3, in the building 100 described in claim 1, The four walls 106 include a third wall 106c and a fourth wall 106d that are perpendicular to the first wall 106a and the second wall 106b and face each other directly. The aforementioned storage device 110 is A rotating shaft portion 111 provided in the vertical direction, It comprises a circular plate portion 112 that is horizontally rotatable around the aforementioned rotating shaft portion 111 and is formed in a circular shape when viewed from above, The top of the circular plate portion 112 is a storage space on which the stored item 1 is placed. The diameter of the circular plate portion 112 is set to be slightly shorter than the distance between the first wall 106a and the second wall 106b, and the distance between the third wall 106c and the fourth wall 106d.

[0009] According to the invention described in claim 2, the circular plate portion 112, which is rotatable horizontally around the rotating shaft portion 111 and is formed in a circular shape in plan view, serves as a storage space on which the stored items 1 can be placed. The diameter of the circular plate portion 112 is set to be slightly shorter than the distance between the first wall 106a and the second wall 106b and the distance between the third wall 106c and the fourth wall 106d. As a result, the circular plate portion 112 can be provided over the largest possible area within the low-ceiling storage room 101, making it possible to store more stored items 1. Moreover, since the circular plate portion 112 does not come into contact with the four walls 106 when rotated horizontally, both the ease of storing and retrieving stored items 1 in the low-ceiling storage room 101 can be improved.

[0010] The invention described in claim 3 is, for example, as shown in Figures 1 to 3, in the building 100 described in claim 2, The storage space is characterized by having a partition section 114 (partition plate section 114) that divides the storage space into multiple sections.

[0011] According to the invention described in claim 3, since the storage space on the circular plate portion 112 is provided with a partition portion 114 (partition plate portion 114) that divides it into multiple sections, the items to be stored in the low-ceiling storage room 101 can be sorted using the partition portion 114 as a boundary. This makes it possible, for example, to sort the items to be stored by type, to sort clothing to suit the seasons, or to sort food items to suit their expiration dates.

[0012] The invention described in claim 4 is, for example, as shown in Figures 1 to 3, in the building 100 described in claim 2, In the low-ceiling storage room 101, a corner storage shelf 120 is installed along the wall 106 in the inner corner formed by the walls 106 that are perpendicular to each other in a plan view. The surface of the corner storage shelf 120 facing the storage device 110 is characterized by being curved in a plan view.

[0013] According to the invention described in claim 4, the side of the corner storage shelf 120 installed in the inner corner of the low-ceiling storage room 101 that faces the storage device 110 is formed in a curved shape in plan view, so that the circular plate portion 112 can be positioned close to the corner storage shelf 120. In other words, the area of ​​the circular plate portion 112 can be made as large as possible, and the corner storage shelf 120 can also be made large enough so that it does not come into contact with the circular plate portion 112, thereby increasing the amount of storage capacity for the stored items 1 in the low-ceiling storage room 101 as much as possible.

[0014] The invention described in claim 5 is, for example, as shown in Figures 4 to 6, in the building 200 described in claim 1, The four walls 206 include a third wall 206c and a fourth wall 206d that are perpendicular to the first wall 206a and the second wall 206b and face each other directly. The aforementioned storage device 210 has an annular shape in plan view, The storage unit is characterized by having an annular transport means (guide rail 211, multiple bases 212) configured to allow the stored items 1 to be transported along the outer edge of the floor 202 of the low-ceiling storage room 201.

[0015] According to the invention described in claim 5, the four walls 206 include a third wall 206c and a fourth wall 206d that are perpendicular to the first wall 206a and the second wall 206b and face each other directly, and the storage device 210 is annular in plan view and is equipped with annular transport means (guide rail 211, multiple bases 212) configured to transport the stored items 1 along the outer edge of the floor 202 of the low ceiling storage room 201. As a result, the stored items 1 placed on the annular transport means can be transported from the front first wall 206a side to the back second wall 206b side, or from the back second wall 206b side to the front first wall 206a side. This improves the ease of retrieving the stored items 1 in the low ceiling storage room 201 and makes effective use of the entire storage space of the low ceiling storage room 201.

[0016] The invention described in claim 6 is, for example, as shown in Figures 4 and 5, in the building 200 described in claim 5, Of the aforementioned low-ceiling storage room 201, the inner part of the annularly formed storage device 210 is designated as the central storage area 202b. The central storage area 202b is characterized in that it is in communication with other floors via a floor hatch 203a provided in the floor 202 or ceiling of the low-ceiling storage room 201.

[0017] According to the invention described in claim 6, the central storage area 202b inside the annularly formed storage device 210 is in communication with other floors via a floor hatch 203a provided in the floor 202 or ceiling of the low-ceiling storage room 201. Therefore, even when the storage items 1 are stored in the storage device 201 and it is not possible to enter the central storage area 202b through the opening 207 in the first wall 206a, the central storage area 202b can be used from other floors, and the storage space in the low-ceiling storage room 201 can be effectively utilized.

[0018] The invention described in claim 7 is, for example, as shown in Figure 6, in the building 300 described in claim 5, In the low-ceiling storage room 301, the inner side of the annularly formed storage device 310 is defined as a drive unit installation area portion 311 in which a drive unit for driving the annular conveying means is installed.

[0019] According to the invention described in claim 7, in the low-ceiling storage room 301, the inner side of the annularly formed storage device 310 is defined as the drive unit installation area portion 311 in which the drive unit for driving the annular conveying means is installed, so that the drive units for driving the annular conveying means can be centralized at one location. Correspondingly, the space where the annular conveying means is installed can be expanded, so that more stored items 1 can be placed thereon, and the storage space in the low-ceiling storage room 201 can be effectively utilized.

[0020] The invention described in claim 8 is, for example, as shown in Figures 1 to 6, in the building 100, 200 according to any one of claims 1 to 7, Of the floors 102, 202 of the low-ceiling storage rooms 101, 201, at least the locations where the storage devices 110, 210 are installed are formed one step lower than the locations of the floors 102, 202 of the low-ceiling storage rooms 101, 201 where the storage devices 110, 210 are not installed, or than the floors 102, 202 of the adjacent rooms 104, 204.

[0021] According to the invention described in claim 8, of the floors 102, 202 of the low-ceiling storage rooms 101, 201, at least the locations where the storage devices 110, 210 are installed are formed one step lower than the locations of the floors 102, 202 of the low-ceiling storage rooms 101, 201 where the storage devices 110, 210 are not installed, or than the floors 102, 202 of the adjacent rooms 104, 204, so that the height position of at least the locations where the storage devices 110, 210 are installed can be made as low as possible. Thereby, the work of placing the stored items 1 onto the storage devices 110, 210 and the work of unloading them can be facilitated, so that the ease of taking out the stored items 1 in the low-ceiling storage rooms 110, 210 can be improved.

[0022] The invention described in claim 9 is, for example, as shown in Figures 1 to 3, in the building 100 described in claim 8, which references claim 2, The upper surface of the circular plate portion 112 and the portion of the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or the floor surface of the floor 102 of the adjacent room 104, are located at approximately the same height.

[0023] According to the invention described in claim 9, since the upper surface of the circular plate portion 112 is at approximately the same height as the portion of the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or the floor surface of the floor 102 of the adjacent room 104, the stored item 1 can be moved by sliding it from the portion of the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or the floor surface of the floor 102 of the adjacent room 104, onto the upper surface of the circular plate portion 112. In other words, even if the stored item 1 is heavy, it becomes easier to put it in and take it out, thus improving the ease of retrieving the stored item 1 in the low-ceiling storage room 110.

[0024] The invention described in claim 10 is, for example, as shown in Figures 4 and 5, in the building 200 described in claim 8, which references claim 5, The storage device 210 includes a plurality of bases 212 configured to slide in conjunction with each other along an annular route 202a (lane groove 202a) formed in the floor 202 of the low-ceiling storage room 201, The multiple bases 212 are used as storage spaces on which the stored items 1 are placed. The above surfaces of the multiple bases 212 are located at approximately the same height as the portion of the floor 202 of the low-ceiling storage room 201 where the storage device 210 is not installed, or the floor surface of the floor 202 of the adjacent room 204.

[0025] According to the invention described in claim 10, the storage device 210 includes a plurality of bases 212 configured to slide in conjunction with each other along an annular route 202a formed on the floor 202 of the low-ceiling storage room 201, and the space on top of the plurality of bases 212 is used as a storage space on which the stored items 1 are placed. As a result, the stored items 1 placed on the plurality of bases 212 can be accurately transported along the annular route 202a, improving the ease of retrieving the stored items 1 from the low-ceiling storage room 201. Furthermore, since the top surfaces of the multiple bases 212 are at approximately the same height as the areas of the floor 202 of the low-ceiling storage room 201 where the storage device 210 is not installed, or the floor surface of the adjacent room 204, the stored items 1 can be moved by sliding them from the areas of the floor 202 of the low-ceiling storage room 201 where the storage device 210 is not installed, or the floor surface of the adjacent room 204, onto the top surfaces of the bases 212. In other words, even if the stored items 1 are heavy, they can be easily taken in and out, thus improving the ease of retrieving stored items 1 from the low-ceiling storage room 210.

[0026] The invention described in claim 11 is, for example, as shown in Figure 6, in the building 300 described in claim 1, The second wall 308, one of the four walls, is characterized in that another opening 309 is formed therein.

[0027] According to the invention described in claim 11, since another opening 309 is formed in the second wall 308 of the four walls, the stored items 1 can be put in and taken out from both the other opening 309 and the opening 307 formed in the first wall 306. In other words, since another opening 309 is formed in the second wall 308, which is located on the back side in the depth direction relative to the first wall 306, the stored items 1 can be put in and taken out from the other opening 309, so that the storage space can be effectively utilized all the way to the back of the low-ceiling storage room 301.

[0028] The invention described in claim 12 relates to the building 100,200 described in claim 1, The storage devices 110 and 210 are characterized by being equipped with stopper parts for stopping the operation of transporting the stored items 1.

[0029] According to the invention described in claim 12, the storage devices 110 and 210 are equipped with stopper parts for stopping the operation of transporting the stored items 1, so that the operation of transporting the stored items 1 by the storage devices 110 and 210 can be stopped by the stopper parts. This prevents the storage devices 110 and 210 from operating while loading or unloading the stored items 1 or while sorting the stored items 1, thereby improving the ease of loading and unloading the stored items 1. [Effects of the Invention]

[0030] According to the present invention, it is possible to improve the ease of retrieving stored items in a low-ceiling storage room, and to make effective use of the entire storage space in the low-ceiling storage room. [Brief explanation of the drawing]

[Figure 6] This is a cross-sectional view showing a portion of the third building, which includes a low-ceiling storage room. [Modes for carrying out the invention]

[0032] Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, but the technical scope of the present invention is not limited to the embodiments and illustrated examples below. Note that the directions in the embodiments and illustrated examples below are set solely for the convenience of explanation.

[0033] [First Embodiment] Figures 1 and 2 are plan cross-sectional views showing a part of the first building 100 equipped with a low-ceiling storage room 101. Figure 3 is a side cross-sectional view showing a part of the first building 100 equipped with a low-ceiling storage room 101. The first building 100 is, for example, a residence, but is not limited to this, and may be a facility other than a residence. The low-ceiling storage room 101 refers to a space with a ceiling height of 0.8m to 1.4m provided between the floor 102 of a specific floor and an intermediate floor 103 provided on a part of this specific floor 102. In this embodiment, the ceiling height of the low-ceiling storage room 101 is 1.4m. The specific floor may be any floor of the first building 100, but in this embodiment it is the first floor. Therefore, the floor 102 of the specific floor is the first floor 102. The low-ceiling storage room 101 is located adjacent to the first-floor room 104, and above the low-ceiling storage room 101, there is an intermediate room 105 with the intermediate floor 103 as its floor.

[0034] The low-ceiling storage room 101 is enclosed by four walls 106. In other words, the low-ceiling storage room 101 is enclosed by the first-floor floor 102, the intermediate floor 103, and the four walls 106. The intermediate floor 103 forms the ceiling of the low-ceiling storage room 101. The first-floor room 104, the low-ceiling storage room 101, and the intermediate room 105 are separated by a wall 106. The wall 106 has an opening 107 for loading and unloading stored items 1 between the low-ceiling storage room 101 and the first-floor room 104, and the opening 107 is opened and closed by a door (not shown). The method of opening and closing the door is not particularly limited. Furthermore, the opening 107 in this embodiment is positioned to avoid the four corners of the low-ceiling storage room 101. However, it is not limited to this, and may be positioned and formed closer to any one of the corners.

[0035] In this embodiment, the four walls 106 are such that the south wall 106, where the opening 107 is formed, is designated as the first wall 106a, and the north wall 106, which is directly opposite the first wall 106a, is designated as the second wall 106b. Furthermore, the walls 106 that are perpendicular to the first wall 106a and the second wall 106b and directly opposite each other are designated as the third wall 106c and the fourth wall 106d. In this embodiment, the third wall 106c is located on the west side, and the fourth wall 106d is located on the east side.

[0036] A rotating storage device 110 is installed on the floor of the low-ceiling storage room 101 (the portion of the first-floor floor 102 that is inside the low-ceiling storage room 101). The rotary storage device 110 of this embodiment includes a rotating shaft portion 111, a circular plate portion 112, a plurality of support travel portions 113, and a plurality of partition plate portions 114.

[0037] The rotating shaft portion 111 is provided between the floor 102 and the ceiling (intermediate floor 103) of the low-ceiling storage room 101, and has a shaft body 111a, a lower end holding portion 111b, an upper end holding portion 111c, and a shaft cover 111d. The shaft body 111a is set to a dimension that is slightly shorter than the ceiling (intermediate floor 103) from the floor 102. The lower end holding portion 111b is a concave member consisting of a circular plate portion and a cylindrical portion, which is fixed to the floor 102 and into which the lower end of the shaft body 111a is inserted. Similarly, the upper end holding portion 111c is a concave member consisting of a circular plate portion and a cylindrical portion, and is fixed to the ceiling (intermediate floor 103), into which the upper end of the shaft body 111a is inserted. The shaft cover 111d covers the portion of the shaft body 111a that is not covered by the lower end retaining portion 111b and the upper end retaining portion 111c. In this type of rotating shaft portion 111, the shaft body 111a is held by the lower end holding portion 111b and the upper end holding portion 111c, allowing it to rotate freely around the shaft.

[0038] The circular plate portion 112 is formed in a circular (perfect circle) shape in plan view, is provided at the lower end of the rotating shaft portion 111, and is arranged parallel to the floor 102. The circular plate portion 112 has a plurality of plate body portions 112a and a plurality of connecting frames 112b. The plate body 112a is formed in a fan shape, and multiple plate body 112a can be connected to form a circular shape in plan view. In addition, one of the multiple plate body 112a has an insertion hole into which the connecting frame 112b is inserted. However, it is not limited to this, and grooves into which the connecting frame 112b fits may be formed on the contact surfaces between the multiple plate body 112a. The connecting frame 112b is connected and fixed at its base end to the lower end of the shaft body 111a of the rotating shaft portion 111. The connecting frame 112b is then inserted into an insertion hole formed in the plate portion body 112a. In other words, the circular plate portion 112 has multiple connecting frames 112b extending radially from the lower end of the rotating shaft portion 111, and multiple plate portion bodies 112a are engaged with these multiple connecting frames 112b. Therefore, when the rotating shaft portion 111 rotates around its axis, the circular plate portion 112 also rotates simultaneously.

[0039] Multiple running support sections 113 are provided on the lower surface of the circular plate section 112 to prevent the circular plate section 112 from bending. In this embodiment, for example, a ball caster that rotates smoothly in all directions is used, but it is not limited to this, and a wheel-type caster or other structure may be used. Furthermore, protective plates 113a are laid on the floor 102 along the track of the running support section 113 to protect the floor 102.

[0040] The partition plate portion 114 is a plate for dividing the space on the circular plate portion 112 into multiple spaces. Its side ends are fixed to the shaft cover 111d of the rotating shaft portion 111, and its lower end is fixed to the upper surface of the circular plate portion 112. In this embodiment, four partition plate portions 114 are used, allowing the space on the circular plate portion 112 to be divided into four spaces. Since the partition plate portion 114 is fixed to the shaft cover 111d and the circular plate portion 112, it rotates together with the rotating shaft portion 111 and the circular plate portion 112. In this embodiment, the partition plate portion 114 is a plate, but it may also be a fence or a mesh. Also, in this embodiment, the side ends of the partition plate portion 114 are fixed to the shaft cover 111d of the rotating shaft portion 111, and the lower end is fixed to the upper surface of the circular plate portion 112, but it may be fixed to either one or the other.

[0041] The space on the circular plate portion 112 may be used as storage space for the stored items 1, as shown in Figure 3, or it may be used as a workspace for a person to stand on and perform storage-related work inside the low-ceiling storage room 101. When used as a workspace for a person, the person can move to the back of the low-ceiling storage room 101 while remaining seated on the circular plate portion 112. In this case, the opening 107 provided in the wall 106 (106a) will function as an entrance and exit.

[0042] Furthermore, in the rotary storage device 110 of this embodiment, the rotation of the circular plate portion 112 around the rotation shaft portion 111 is performed manually. That is, a person pushes or pulls the circular plate portion 112 or the partition plate portion 114 in the rotational direction to rotate the circular plate portion 112 around the rotation shaft portion 111. This makes it possible to switch the storage space on the circular plate portion 112 that appears in the opening 107. However, it is not limited to such manual operation, and the circular plate portion 112 may be rotated electrically by a motor. In other words, the rotation of the rotary storage device 110 may be manual or electric. In the case of electric operation, it may be connected to an external controller so that it can be operated from the external controller.

[0043] Although not shown in the diagram, the rotating storage device 110 is equipped with a stopper to stop the rotation of the circular plate portion 112. Examples of such stoppers include those that engage between the circular plate portion 112 and the floor 102, those that protrude from the wall 106 or ceiling and contact the partition plate portion 114, and those that fix the travel support portion 113. It is desirable that the means for releasing the stopper be provided not only near the opening 107, but also on the second wall 106b located at the back of the low-ceiling storage room 101 in the depth direction. This ensures that even if the stopper is activated from the outside after a person has entered the back of the low-ceiling storage room 101 while standing on the top surface of the circular plate 112, the stopper can be released from inside the low-ceiling storage room 101.

[0044] When storing item 1 in the low-ceiling storage room 101, a person in the adjacent first-floor room 104 places item 1 into the low-ceiling storage room 101 through the opening 107 and stores it on the top surface of the circular plate section 112. After placing item 1 on the circular plate section 112, the circular plate section 112 is rotated horizontally to move item 1 from in front of the opening 107. This reveals the next storage space partitioned by the partition plate section 114, allowing other items 1 to be placed on the top surface of the circular plate section 112 and stored. By repeating this procedure, items 1 can be successively placed on the top surface of the circular plate section 112 and stored. When retrieving item 1, the person retrieving it can do so from the opening 107 while remaining in the adjacent first-floor room 104. In other words, the rotary storage device 110 is configured to be able to transport the stored item 1 by making it circulate between the first wall 106a and the second wall 106b while the stored item 1 is placed on it.

[0045] Furthermore, the low-ceiling storage room 101 is formed in a rectangular shape in plan view, and a circular rotating storage device 110 is installed inside it in plan view. As a result, arc-shaped right-angled triangular regions are formed at each of the four corners of the low-ceiling storage room 101. The four corners referred to here are the inner corners formed by the perpendicular walls 106 in plan view. In order to make effective use of these corner areas, in this embodiment, corner storage shelves 120 are installed in the four corners of the low-ceiling storage room 101. In other words, corner storage shelves 120 are installed in the four inner corners of the low-ceiling storage room 101. However, if an opening 107 is positioned close to any one of the corners, a corner storage shelf 120 will not be installed in that corner, and the number of corner storage shelves 120 installed is at the discretion of the resident.

[0046] The corner storage shelf 120 is a storage shelf that opens toward the rotating storage device 110, and the side facing the rotating storage device 110 (which is the front of the corner storage shelf 120) is formed in a curved arc shape when viewed from above. Its curvature is set to be slightly greater than the curvature of the outer edge of the circular plate portion 112. In this embodiment, the corner storage shelf 120 has a shelf board 121 in the central part. The shelf board 121 may be omitted, in which case the stored items 1 are stacked on the bottom plate 122. The height of the top surface of the bottom plate 122 is set to be approximately equal to the height of the top surface of the circular plate portion 112. The top panel 123 is positioned as close as possible to the ceiling (intermediate floor 103) of the low-ceiling storage room 101. In other words, the vertical dimensions of the corner storage shelf 120 are set to be approximately equal to the ceiling height of the low-ceiling storage room 101. The back panel 124 is installed along the wall 106.

[0047] In this embodiment, the space on the circular plate portion 112 is used as storage space for the stored item 1. In this case, since it is difficult for a person to enter the back of the low-ceiling storage room 101, a storage robot 130 may be placed in the low-ceiling storage room 101, as shown in Figure 3.

[0048] The storage robot 130 is mounted and installed on the ceiling (intermediate floor 103). Since the partition plate section 114 rotates together with the rotating shaft section 111 and the circular plate section 112, the upper end of the partition plate section 114 is left in a gap between it and the ceiling. In other words, the storage robot 130 is positioned in the space between the upper end of the partition plate section 114 and the ceiling (intermediate floor 103).

[0049] The storage robot 130 includes a slide rail 131, a main operating unit 132, an arm unit 133, a wire 134, a gripper 135, and a storage item detection sensor 136. In this embodiment, multiple storage robots 130 are installed. Specifically, in the low-ceiling storage room 101, the area near the opening 107 is accessible by human hands from the opening 107, so multiple storage robots 130 are installed in positions where they cannot be reached by human hands from the opening 107.

[0050] The slide rail 131 is installed on the ceiling (intermediate floor 103) and extends from the rotating shaft 111 toward the wall 106 or the corner storage shelf 120.

[0051] The main operating unit 132 engages with the slide rail 131 and moves along the slide rail 131. The main operating unit 132 has a built-in motor, which functions as a drive source when moving along the slide rail 132 and as a drive source when rotating the arm unit 133. Furthermore, the main operating unit 132 is equipped with a communication unit (not shown) and can receive operations from an external controller and move along the slide rail 131.

[0052] The base end of the arm section 133 is mounted to the main operating section 132 so as to be able to rotate horizontally around the axis of rotation. The arm section 133 is also configured to be extendable and retractable by having a base arm and a tip arm connected to the base arm via an extension mechanism. The arm section 133 has a built-in motor, which functions as a drive source for the extension and retraction mechanism of the tip arm and as a drive source for the wire 134 unwinding and winding mechanism, which will be described later.

[0053] The wire 134 is unfurled from the tip of the end arm of the arm section 133, and a gripper 135 is attached to its tip. The length of the wire 134 is set to the length required for the gripper 135 to reach the upper surface of the circular plate section 112. The wire 134 unwinding and winding mechanism is built into the base end of the arm 133, and the wire 134 is unwinding and winding by a motor (not shown).

[0054] The gripper 135 is for gripping the stored item 1 and has multiple claws that open and close. The gripper 135 has a built-in motor, which functions as the drive source when the multiple claws open and close. Furthermore, the multiple claws are folded when the storage robot 130 is not in use. When in use, they are unfolded from their folded state. This prevents the multiple claws from coming into contact with the rotating partition plate 114.

[0055] The storage object detection sensor 136 is attached to the tip of the arm 133 and can detect the presence or absence of the storage object 1 below. Therefore, the person operating the storage robot 130 with the controller can perform the storage operation of the storage object 1 while detecting the presence or absence of the storage object 1 using the storage object detection sensor 136. Alternatively, a camera may be installed on the inner wall surface of the wall 106 of the low-ceiling storage room 101, and the image from the camera may be transmitted to the controller. The stored item detection sensor 136 itself may be a camera, and the image (video) captured by the camera is transmitted to the controller via the communication unit. Furthermore, the stored item detection sensor 136 may be provided not only at the tip of the arm portion 133, but also at multiple parts of the storage robot 130.

[0056] The motors built into the main operating unit 132, the motors built into the arm unit 133, and the motors built into the gripper 135 are connected by communication lines connected to the communication unit of the main operating unit 132. Therefore, the operation of the storage robot 130 can be fully controlled by an external controller. The external controller may be a dedicated controller for the storage robot 130 (for example, controller 30 in Figure 6), or it may be an information and communication terminal such as a smartphone, tablet, or PC.

[0057] As described above, the storage robot 130 is capable of the following operations: the main operating unit 132 moving along the slide rail 131; the arm 133 rotating horizontally relative to the main operating unit 132 around the rotation axis at its base end; the tip arm of the arm 133 extending and retracting relative to the base arm; the wire 134 being unfurled; the wire 134 being wound up; the multiple claws of the gripper 135 opening and closing; and the multiple claws of the gripper 135 folding and unfolding. Therefore, the storage robot 130 does not obstruct the rotation of the rotary storage device 110, and allows the storage items 1 to be moved over a wide range when sorting the storage items 1 that have been placed on the rotary storage device 110.

[0058] In this embodiment, the floor of the low-ceiling storage room 101 where the rotating storage device 110 and the corner storage shelf 120 are installed is set so that the height of the floor surface is the same as the height of the floor surface on the first floor 102, but this is not limited to this. That is, at least the area of ​​the floor of the low-ceiling storage room 101 where the rotating storage device 110 is installed may be set one step lower than the height of the floor surface on the first floor 102. More specifically, the floor 102 of the low-ceiling storage room 101, at least in the area where the storage device 110 is installed, may be formed at a lower level than the area of ​​the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or the floor 102 of the adjacent first-floor room 104. In other words, one possible height position for the floor 102 of the low-ceiling storage room 101 is a first pattern where it is at the same height as the floor 102 of the first-floor room 104. Next, there is a second pattern in which the entire floor 102 of the low-ceiling storage room 101 is set one step lower than the floor 102 of the adjacent first-floor room 104. Next, there is a third pattern in which, of the floor 102 of the low-ceiling storage room 101, only the area where the rotating storage device 110 is installed is set one step lower than the floor 102 of the adjacent first-floor room 104. In the second and third patterns, the height position of the upper surface of the circular plate portion 112 and the height position of the floor surface of the floor 102 may be set to be approximately equal, or the circular plate portion 112 may be slightly higher or slightly lower than the floor 102.

[0059] If at least the area on the floor 102 of the low-ceiling storage room 101 where the storage device 110 is installed is lower than the area on the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or lower than the floor 102 of the first-floor room 104, then the height of at least the area where the storage device 110 is installed can be made as low as possible. In such a case, the work of placing and removing stored items 1 from the storage device 110 can be made easier, thereby improving the ease of retrieving stored items 1 from the low-ceiling storage room 110. Furthermore, if the upper surface of the circular plate portion 112 is at approximately the same height as the area of ​​the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or the floor surface of the floor 102 of the first-floor room 104, the stored item 1 can be moved by sliding it from the area of ​​the floor 102 of the low-ceiling storage room 101 where the storage device 110 is not installed, or the floor surface of the floor 102 of the first-floor room 104, onto the upper surface of the circular plate portion 112. In other words, even if the stored item 1 is heavy, it becomes easier to put it in and take it out, thus improving the ease of retrieving the stored item 1 in the low-ceiling storage room 110.

[0060] This embodiment provides the following excellent effects. In other words, the four walls 106 surrounding the low-ceiling storage room 101 include a first wall 106a located between the low-ceiling storage room 101 and the adjacent room 104, with an opening 107 formed therein, and a second wall 106b directly opposite the first wall 106a. The low-ceiling storage room 101 is equipped with a rotary storage device 110 that is configured to transport the stored items 1 in a state where they are placed on it, by circulating the stored items 1 between the first wall 106a and the second wall 106b. Thus, the stored items 1 can be loaded and unloaded from the opening 107 in the first wall 106a to the rotary storage device 110. Furthermore, if the stored items 1 are transported to the second wall 106b side at the back by the rotary storage device 110 while they are placed on it, the stored items 1 can be stored at the back of the low-ceiling storage room 101. Furthermore, when retrieving items 1 stored at the back of the low-ceiling storage room 101, the items 1 can be easily removed from the opening 107 by transporting them to the front first wall 106a side using the rotating storage device 110. This improves the ease of retrieving items 1 from the low-ceiling storage room 101 and makes effective use of the entire storage space of the low-ceiling storage room 101.

[0061] Furthermore, the circular plate portion 112, which is freely rotatable horizontally around the rotating shaft portion 111 and is formed in a circular shape in plan view, serves as a storage space on which the stored items 1 can be placed. The diameter of the circular plate portion 112 is set to be slightly shorter than the distance between the first wall 106a and the second wall 106b, and the distance between the third wall 106c and the fourth wall 106d. This allows the circular plate portion 112 to be provided over the largest possible area within the low-ceiling storage room 101, making it possible to store more stored items 1. Moreover, since the circular plate portion 112 does not come into contact with the four walls 106 when rotated horizontally, both the ease of storing and retrieving stored items 1 in the low-ceiling storage room 101 can be improved.

[0062] Furthermore, since the storage space above the circular plate section 112 is equipped with a partition plate section 114 that divides it into multiple sections, the items to be stored in the low-ceiling storage room 101 can be sorted using the partition plate section 114 as a boundary. This makes it possible, for example, to sort the items to be stored by type, to sort clothing to suit the seasons, or to sort food items to suit their expiration dates.

[0063] Furthermore, the side of the corner storage shelf 120 installed in the inner corner of the low-ceiling storage room 101 that faces the rotating storage device 110 is curved in plan view, so the circular plate portion 112 can be positioned close to the corner storage shelf 120. In other words, the area of ​​the circular plate portion 112 can be made as large as possible, and the corner storage shelf 120 can be made large enough so that it does not come into contact with the circular plate portion 112, thereby maximizing the storage capacity of the stored items 1 in the low-ceiling storage room 101.

[0064] Furthermore, the rotary storage device 110 is equipped with a stopper to stop the operation of transporting the stored items 1. The stopper allows the rotary storage device 110 to stop transporting the stored items 1. This prevents the rotary storage device 110 from operating while the stored items 1 are being loaded or unloaded, or while sorting the stored items 1, thereby improving the ease of loading and unloading the stored items 1.

[0065] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to achieve virtually zero carbon dioxide emissions, and for the achievement of the Sustainable Development Goals (SDGs). In this embodiment, the entire storage space within the low-ceiling storage room 101 can be effectively utilized, enabling proper management of the stored items 1, which can contribute to reducing resource waste and food loss, for example.

[0066] [Second Embodiment] Next, a second embodiment of the present invention will be described with reference to the drawings. For the sake of convenience, elements common to the first embodiment described above will be denoted by the same reference numerals, and their descriptions will be omitted or simplified. The description will focus on components that differ from the first embodiment.

[0067] Figure 4 is a plan cross-sectional view showing a part of the second building 200 equipped with a low-ceiling storage room 201. Figure 5 is a perspective view showing a part of a rotating storage device 210 installed in the low-ceiling storage room 201. The second building 200 is, for example, a residence, but is not limited to this, and may be a facility other than a residence. The low-ceiling storage room 201 refers to a space with a ceiling height of 0.8m to 1.4m provided between the floor 202 of a specific floor and an intermediate floor (not shown) provided on a part of this specific floor 202. In this embodiment, the ceiling height of the low-ceiling storage room 201 is 1.4m. The specific floor can be any floor of the second building 200, but in this embodiment it is the first floor. Therefore, the floor 202 of the specific floor is the first floor 202. The low-ceiling storage room 201 is located adjacent to the first-floor room 204, and above the low-ceiling storage room 201 is an intermediate room (not shown) with an intermediate floor.

[0068] The low-ceiling storage room 201 is rectangular in shape in plan view and is surrounded by four walls 206. In other words, the low-ceiling storage room 201 is surrounded by the first-floor 202, the intermediate floor, and the four walls 206. The intermediate floor constitutes the ceiling of the low-ceiling storage room 201. The first-floor room 204, the low-ceiling storage room 201, and the intermediate room are separated by a wall 206. The wall 206 has an opening 207 for loading and unloading stored items 1 between the low-ceiling storage room 201 and the first-floor room 204, and the opening 207 is opened and closed by a door (not shown). The method of opening and closing the door is not particularly limited.

[0069] In this embodiment, the four walls 206 are such that the south wall 206, where the opening 207 is formed, is designated as the first wall 206a, and the north wall 206, which is directly opposite the first wall 206a, is designated as the second wall 206b. Furthermore, the walls 206 that are perpendicular to the first wall 206a and the second wall 206b and directly opposite each other are designated as the third wall 206c and the fourth wall 206d. In this embodiment, the third wall 206c is located on the west side, and the fourth wall 206d is located on the east side.

[0070] A rotating storage device 210 is installed on the floor of the low-ceiling storage room 201 (the portion of the first-floor floor 202 that is located within the low-ceiling storage room 201). The rotary storage device 210 of this embodiment includes a guide rail 211 and a plurality of bases 212.

[0071] Furthermore, a lane groove 202a for installing a rotating storage device 210 is formed in the floor 202 of a specific floor. Alternatively, the floor of the low-ceiling storage room 201 may be set one step lower than the first-floor floor 202 by the amount to which the rotating storage device 210 is installed.

[0072] The lane groove 202a is formed to follow the wall 206 surrounding the low-ceiling storage room 201, which is orthogonal in a plan view, and the four corners of the lane groove 202a are formed in a curved shape. That is, the lane groove 202a has four straight paths that follow the wall 206 and four curved paths that curve at 90 degrees, which are arranged alternately.

[0073] The guide rail 211 has four straight sections and four curved sections, with these straight and curved sections arranged alternately. The straight and curved sections are also integrally or integrally formed to create a ring-shaped (endless) structure. The straight section of the guide rail 211 is positioned along the straight path of the lane groove 202a, and the curved section of the guide rail 211 is positioned along the curved path of the lane groove 202a. Therefore, the curved section is formed with a 90-degree curve in plan view. In other words, such a guide rail 211 is formed in a shape that resembles a rounded rectangle in plan view, or a number "0" in a font that is close to a rounded rectangle. In other words, the guide rail 211 is installed along the outer edge of the floor 202, with a gap of the length of the base 212 from the outer edge of the floor 202, and the parts corresponding to the four corners of the low-ceiling storage room 101 are curved.

[0074] The base 212 is formed in a circular shape when viewed from above, and its top surface serves as a storage space on which the stored item 1 is placed and stored. Such a base 212 has a slider portion 212a provided on its lower surface that slidably engages with the guide rail 211. This allows the base 212 to slide along the guide rail 211. In other words, it can slide along the lane groove 202a formed in the floor 202 of the low-ceiling storage room 201.

[0075] In the curved section of the guide rail 211, adjacent bases 212 are in close proximity to each other. Therefore, multiple bases 212 are arranged so that no large gaps are formed between them and the annular guide rail 211.

[0076] Furthermore, in the rotary storage device 210 of this embodiment, the sliding movements of the multiple bases 212 are all linked, and these sliding movements of the multiple bases 212 are performed manually. That is, a person pushes or pulls at least one of the multiple bases 212 in the sliding direction to slide the multiple bases 212 along the guide rail 211. This makes it possible to switch the storage space on the bases 212 that appear in the opening 207. However, this is not limited to manual operation, and the multiple bases 212 may be slid electrically by a motor. In other words, the sliding movements of the multiple bases 212 may be manual or electric. In the case of electric operation, they may be connected to an external controller so that they can be operated from the external controller.

[0077] Although not shown in the figures, the rotary storage device 210 is equipped with stopper parts for stopping the sliding movement of the multiple bases 212. Examples of such stopper parts include those that protrude from the bottom or side wall surface of the lane groove 202a and are interposed between two bases 212, those that connect one of the bases 212 to the floor 202, and those that are provided on the guide rail 211 and fix the slider part 212a. In this embodiment, since all of the multiple bases 212 slide in conjunction as described above, if the movement of one of the bases 212 can be stopped, the movement of all of the bases 212 can be stopped.

[0078] When storing item 1 in the low-ceiling storage room 201, a person in the adjacent first-floor room 204 places item 1 into the low-ceiling storage room 201 through the opening 207 and stores it on the top surface of the base 212. After placing item 1 on the base 212, the interconnected bases 212 are slid along the guide rail 211 to move item 1 in front of the opening 207. This causes the next base 212 to appear, allowing other items to be stored by placing them on the top surface of the next base 212. By repeating this procedure, items 1 can be stored one after another on the top surfaces of multiple bases 212. When retrieving item 1, the person retrieving it can do so from the opening 207 while remaining in the adjacent first-floor room 204. In other words, the rotary storage device 210 is configured to be able to transport the stored item 1 by making it circulate between the first wall 206a and the second wall 206b while the stored item 1 is placed on it.

[0079] As described above, the rotating storage device 210 is installed along the four walls 206 of the low-ceiling storage room 201, so an area is formed in the center of the low-ceiling storage room 201 where the rotating storage device 210 is not installed. In this embodiment, this area is also used as storage space. Hereinafter, the storage space in the center of the low-ceiling storage room 201 will be referred to as the central storage area 202b.

[0080] In this embodiment, the central storage area 202b is located in the inner region of the lane groove 202a. Therefore, a rib wall 202c is erected along the outer edge of the central storage area 202b to prevent contact between the stored items 1, which are moved on multiple bases 212, and the stored items 1 stored in the central storage area 202b. The rib wall 202c is set to a height of several centimeters.

[0081] If the stored items 1 are placed on all of the multiple bases 212, it is not possible to put the stored items 1 in or out of the central storage area 202b from the opening 107. Therefore, in this embodiment, access is possible from an intermediate room located directly above the low-ceiling storage room 201. In other words, an opening 203a is formed in the intermediate floor that makes up the ceiling of the low-ceiling storage room 201, located above the central storage area 202b, for use as an opening. A cover (not shown) for opening and closing the opening 203a is provided on the edge of the intermediate floor on the side of the opening 203a, and when the opening 203a is closed, the cover functions as the floor of the intermediate room. In short, a floor hatch (opening 203a and cover) is provided in the intermediate floor that makes up the ceiling of the low-ceiling storage room 201, located above the central storage area 202b, and the central storage area 202b can be accessed from the intermediate room on the upper floor.

[0082] A lifting mechanism 208 is provided between the central storage area 202b and the intermediate room. In this embodiment, the lifting mechanism 208 is a folding ladder and is attached to the edge of the intermediate floor on the side of the opening 203a. However, the type of lifting mechanism 208 is not limited to a folding ladder; for example, a non-folding ladder may be used, or a storage shelf formed in a staircase shape may be installed within the central storage area 202b.

[0083] This embodiment provides the following excellent effects. In other words, the four walls 206 surrounding the low-ceiling storage room 201 include a first wall 206a located between the low-ceiling storage room 201 and the adjacent room 204, with an opening 207 formed therein, and a second wall 206b directly opposite the first wall 206a. The low-ceiling storage room 201 is equipped with a rotary storage device 210 that is configured to transport the stored item 1 in a circumferential manner between the first wall 206a and the second wall 206b, so that the stored item 1 can be moved in and out of the rotary storage device 210 through the opening 207 in the first wall 206a. Furthermore, if the stored item 1 is transported to the second wall 206b at the back by the rotary storage device 210 while it is loaded, the stored item 1 can be stored at the back of the low-ceiling storage room 201. Furthermore, when retrieving the stored items 1 from the back of the low-ceiling storage room 201, the items 1 can be easily removed from the opening 207 by transporting them to the front first wall 206a side using the rotating storage device 210. This improves the ease of retrieving the stored items 1 from the low-ceiling storage room 201 and makes effective use of the entire storage space of the low-ceiling storage room 201.

[0084] Furthermore, the four walls 206 include a third wall 206c and a fourth wall 206d that are perpendicular to the first wall 206a and the second wall 206b and directly opposite each other. The rotating storage device 210 is annular in plan view and is equipped with annular transport means (guide rails 211, multiple bases 212) that allows the stored items 1 to be transported along the outer edge of the floor 202 of the low ceiling storage room 201. As a result, the stored items 1 placed on the annular transport means can be transported from the front first wall 206a side to the back second wall 206b side, or from the back second wall 206b side to the front first wall 206a side. This improves the ease of retrieving stored items 1 from the low ceiling storage room 201 and makes effective use of the entire storage space of the low ceiling storage room 201.

[0085] Furthermore, since the central storage area 202b inside the annularly formed rotating storage device 210 is connected to other floors via a floor hatch 203a provided in the floor 202 or ceiling of the low-ceiling storage room 201, even when the storage items 1 are stored in the rotating storage device 201 and it is not possible to enter the central storage area 202b through the opening 207 in the first wall 206a, the central storage area 202b can be accessed from other floors, and the storage space within the low-ceiling storage room 201 can be effectively utilized.

[0086] Furthermore, since at least the area of ​​the floor 202 of the low-ceiling storage room 201 where the rotating storage device 210 is installed is formed at a lower level than the area of ​​the floor 202 of the low-ceiling storage room 201 where the rotating storage device 210 is not installed, or the floor 202 of the first-floor room 204, the height position of at least the area where the rotating storage device 210 is installed can be made as low as possible. This makes it easier to place and remove the stored items 1 from the rotating storage device 210, thereby improving the ease of retrieving the stored items 1 in the low-ceiling storage room 210.

[0087] Furthermore, the rotary storage device 210 is equipped with a plurality of pedestals 212 that are configured to slide in conjunction with each other along an annular route 202a formed on the floor 202 of the low-ceiling storage room 201, and the space on top of the plurality of pedestals 212 is used as a storage space on which the stored items 1 can be placed. As a result, the stored items 1 placed on the plurality of pedestals 212 can be accurately transported along the annular route 202a, improving the ease of retrieving the stored items 1 from the low-ceiling storage room 201. Furthermore, since the top surfaces of the multiple bases 212 are at approximately the same height as the areas of the floor 202 of the low-ceiling storage room 201 where the rotating storage device 210 is not installed, or the floor surface of the adjacent room 204, the stored items 1 can be moved by sliding them from the areas of the floor 202 of the low-ceiling storage room 201 where the rotating storage device 210 is not installed, or the floor surface of the adjacent room 204, onto the top surfaces of the bases 212. In other words, even if the stored items 1 are heavy, they can be easily taken in and out, thus improving the ease of retrieving stored items 1 from the low-ceiling storage room 210.

[0088] Furthermore, the rotary storage device 210 is equipped with a stopper to stop the operation of transporting the stored items 1. The stopper allows the rotary storage device 210 to stop transporting the stored items 1. This prevents the rotary storage device 210 from operating while the stored items 1 are being loaded or unloaded, or while sorting the stored items 1, thereby improving the ease of loading and unloading the stored items 1.

[0089] Furthermore, in recent years, there has been a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to achieve virtually zero carbon dioxide emissions, and for the achievement of the Sustainable Development Goals (SDGs). In this embodiment, the entire storage space within the low-ceiling storage room 201 can be effectively utilized, enabling proper management of the stored items 1, which can contribute to reducing resource waste and food loss, for example.

[0090] [Variation] The embodiments to which the present invention can be applied are not limited to those described above, and can be modified as appropriate without departing from the spirit of the invention. Modifications are described below. The following modifications may be combined as much as possible. Furthermore, in each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and their descriptions are omitted or simplified.

[0091] [Variation 1] Figure 6 is a plan cross-sectional view showing a part of the third building 300 equipped with a low-ceiling storage room 301. In this modified example, the low-ceiling storage room 301 refers to a space with a ceiling height of 0.8m to 1.4m, provided between the floor 302 of a specific floor in the third building 300 and an intermediate floor (not shown) provided above a part of the floor 302 of this specific floor. In this modified example, the ceiling height of the low-ceiling storage room 301 is 1.4m. The low-ceiling storage room 301 is located adjacent to the first room 304 and the second room 305. More specifically, the low-ceiling storage room 301 is located between the first room 304 and the second room 305. Furthermore, above the low-ceiling storage room 301, there is an intermediate room (not shown) with an intermediate floor as its floor level.

[0092] The first room 304, the low-ceiling storage room 301, and the intermediate room are separated by a first wall 306. The first wall 306 has a first opening 307 for moving between the low-ceiling storage room 301 and the first room 304, and the first opening 307 may be opened and closed by a door.

[0093] The second room 305, the low-ceiling storage room 301, and the intermediate room are separated by a second wall 308. The second wall 308 has a second opening 309 for moving between the low-ceiling storage room 301 and the second room 305, and the second opening 309 may be opened and closed by a door.

[0094] Of the four walls, the first wall 306, where the first opening 307 is formed, is located on the east side, and the second wall 308, where the second opening 309 is formed, is located on the west side. The first wall 306 and the second wall 308 are positioned directly opposite each other (i.e., parallel). In this modified example, the wall located on the south side is designated as the third wall, and the wall located on the north side is designated as the fourth wall.

[0095] A rotary storage device 310 is installed on the floor of the low-ceiling storage room 301. The rotary storage device 310 in this modified example employs a belt conveyor system and is arranged to circulate within the low-ceiling storage room 301. Specifically, the belt conveyor system of the rotary storage device 310 in this modified example includes a conveyor for straight sections and corner conveyors that can change the direction of movement of the storage units 2 by 90 degrees at the four corners of the low-ceiling storage room 301. The straight section conveyor and the corner conveyor then constitute an annular conveying means. Each part of the belt conveyor system comprises a belt on which the contents 1 are placed, multiple pulleys around which the belt is wound and which transmit power from the drive unit to the belt, and a support frame that rotatably supports the multiple pulleys. Furthermore, the mechanical unit 311, which is the core of the belt conveyor system, is located in the center of the belt conveyor system. The mechanical unit 311 is equipped with a drive unit that rotates multiple pulleys in each part of the conveyor, and a drive control unit that controls the operation of the drive unit. In other words, the inside of the annular rotary storage device 310 equipped with an annular conveying means (the mechanical unit 311) is a drive unit installation area where the drive unit for driving the annular conveying means is installed.

[0096] The drive control unit is connected to the controller 30 via a communication line 110a so as to be able to communicate, and is set to receive control signals from the controller 30 and to be able to control the operation of the drive unit. The drive unit receives power from a power supply unit (not shown). More specifically, the drive control units of each belt conveyor are controlled by the controller 30.

[0097] In this modified example, the storage item 1 stored in the low-ceiling storage room 301 is a storage container 1 capable of storing various items, and the storage container 1 is stored in the low-ceiling storage room 301 while resting on a rotating storage device 310. Therefore, residents can transport the storage unit 2 to the back of the low-ceiling storage room 301 without having to go all the way inside.

[0098] Furthermore, the rotating storage device 310 can transport the storage unit 2 by circling around the low-ceiling storage room 301. Therefore, the storage unit 2 stored in the low-ceiling storage room 301 from the first room 304 can be transported to the second room 305 and taken out into the second room 305 through the second opening 309, or it can be transported to the first room 304 and taken out again into the first room 304 through the first opening 307.

[0099] According to this modified version, the belt conveyor system, which is the rotary storage device 310, is configured to circulate within the low-ceiling storage room 301. Therefore, even if the storage container 1, which is the stored item 1, is stored in the back of the low-ceiling storage room 301, the storage unit 2 can be moved by operating the rotary storage device 310. As a result, the contents of the storage container 1 can be stored in the low-ceiling storage room 301 in a way that does not reduce their frequency of use, and the contents of the storage container 1 stored in the low-ceiling storage room 301 can be managed efficiently.

[0100] Furthermore, the inside of the annularly formed rotary storage device 310 within the low-ceiling storage room 301 is designated as a drive unit installation area 311 where the drive unit for driving the belt conveyor is installed. This allows the drive unit for driving the belt conveyor to be concentrated in one place. As a result, the space where the belt conveyor is installed can be expanded, making it possible to load more stored items 1 and effectively utilize the storage space within the low-ceiling storage room 201.

[0101] Furthermore, since a second opening 309 is formed in the second wall 308 of the four walls, the stored items 1 can be put in and taken out from both the second opening 309 and the first opening 307 formed in the first wall 306. In other words, since a second opening 309 is also formed in the second wall 308, which is located at the back in the depth direction relative to the first wall 306, the stored items 1 can be put in and taken out from the second opening 309 as well, the storage space can be effectively utilized all the way to the back of the low-ceiling storage room 301.

[0102] [Variation 2] In the first and second embodiments described above, a low-ceiling storage room with a ceiling height of 0.8m to 1.4m was provided between the floor of a specific floor and an intermediate floor provided above a part of the floor of that specific floor. However, in this modified example, the low-ceiling storage room is provided between an intermediate floor provided above a part of the floor of a specific floor and the floor of the upper floor, and its ceiling height is set to 0.8m to 1.4m.

[0103] According to this modified version, the low-ceiling storage room is located between an intermediate floor, which is situated above a portion of the floor on a specific floor, and the floor of the upper floor. This allows the low-ceiling storage room to be positioned closer to the ceiling of that specific floor. In other words, the low-ceiling storage room can be used like a loft or installed on a stair landing, allowing for a wider variety of layouts when introducing a low-ceiling storage room into a house. In short, it becomes possible to place low-ceiling storage rooms equipped with rotating storage devices in various locations within a house, contributing to the effective use of interior space.
