[0009] (Embodiment) A mobile scanning device and a scanning device holder according to an embodiment of the present invention will be described below. FIG. 1 is a side view showing a mobile scanning device 1 and a scanning device holder 10 according to an embodiment of the present invention. The mobile scanning device 1 continuously acquires photographic data of a scanning target such as a wall, and visualizes spatial information. The mobile scanning device 1 includes a scanning device S and a scanning device holder 10 that holds and moves the scanning device S. The scanning device S is, for example, a smartphone.

[0010] The scanning device holder 10 includes a main body 11, a movable mounting portion 12, a fall prevention portion 13, and a movable portion 14. The main body 11 is formed as an elongated member that is extended in the longitudinal direction, and is adapted to expand and contract in the longitudinal direction N. The main body 11 is provided with a moving part 14 that slides the moving mounting part 12 in the longitudinal direction N. The moving part 14 includes a pulley part 141 and a string part 142 . The pulley parts 141 are provided at both ends of the main body 11 in the longitudinal direction N. The pulley parts 141 are rotatably attached to both ends of the main body 11. A string part 142 is wound around these pulley parts 141. The string portion 142 is a long string-like member made of, for example, a wire. The movable mounting part 12 is attached to the main body part 11 so as to be slidable in the longitudinal direction N. The movable mounting part 12 is attached to the string part 142. With this configuration, when the string portion 142 is moved and rotated in the longitudinal direction N, the pulley portions 141 at both ends rotate, causing the movable mounting portion 12 to slide in the longitudinal direction N via the string portion 142.

[0011] As shown in FIGS. 2 and 3, the movable mounting portion 12 includes a clamping portion 121 and a holding portion 122. The clamping portion 121 includes a tire portion 121A (rotating body), an annular portion 121B, a suspension portion 121D (biasing portion), and a rotating shaft portion 121E. The annular portion 121B is formed in an annular shape, with a hollow central portion. The main body portion 11 is adapted to pass through the hollow of the annular portion 121B. Three base shaft portions 121C are provided in the annular portion 121B at equal intervals in the circumferential direction of the main body portion 11 in a plan view. Each of the base shaft portions 121C is provided with a suspension portion 121D extending inward in the main body radial direction K of the main body portion 11. The suspension parts 121D are provided with ring-shaped spring parts made of resin such as rubber, and are configured to bias inward in the main body radial direction K. Rotation shaft parts 121E are provided at the tip parts of the suspension parts 121D, respectively.

[0012] The rotating shaft portions 121E extend in a direction perpendicular to the longitudinal direction N and the main body radial direction K. That is, the rotating shaft portions 121E extend in a direction perpendicular to the main body radial direction K in a plan view. Tire portions 121A are rotatably provided on the rotating shaft portions 121E, respectively. The tire portions 121A are made of a resin material such as rubber. These three tire portions 121A come into contact with the outer circumferential surface of the main body portion 11 and sandwich the main body portion 11 inward in the radial direction K of the main body. With this configuration, when the main body 11 is passed through the center of the three tire portions 121A at the center of the annular portion 121B, these three tire portions 121A come into contact with the outer peripheral surface of the main body 11 and are pressed outward in the main body radial direction K. As the suspension portions 121D contract, each tire portion 121A is disposed outward in the main body radial direction K of the main body 11. The restoring force of the spring portions of the suspension portions 121D urges each tire portion 121A inward in the main body radial direction K, thereby sandwiching the main body 11. When the annular portion 121B is moved in the longitudinal direction N from this state, the three tire portions 121A rotate about the rotation shaft portion 121E and move in the longitudinal direction N while sandwiching the main body 11. At this time, the spring portions of the suspension portions 121D expand and contract to absorb vibrations and impacts in the main body radial direction K from the tire portions 121A. Further, a holding portion 122 is provided on the annular portion 121B. The holding portion 122 is configured to hold the scanning device S in a state in which the scanning device S is arranged along the longitudinal direction N when viewed from the side. In other words, the holding portion 122 is configured to hold the scanning device S in parallel with the main body portion 11.

[0013] Further, as shown in FIGS. 4 and 5, a fall prevention part 13 is provided inside the tire part 121A. The fall prevention part 13 includes an expandable part 131 (a restricting part) and an engaging part 133 (a restricting part). The expandable portion 131 is formed in a plate shape extending in the tire radial direction L of the tire portion 121A. This expandable portion 131 is connected to a connecting shaft A provided at one end of the connecting portion 134, and is configured to rotate in synchronization with the rotation of the tire portion 121A. The expandable portion 131 expands and contracts in the tire radial direction L. That is, the expandable portion 131 expands and contracts in the tire radial direction L between a release position D, where both ends of the expandable portion 131 are not in contact with the engaging portion 133 in the circumferential direction, and a restriction position E, where both ends are in contact with the engaging portion 133 in the circumferential direction. The expandable portion 131 is biased inward in the tire radial direction L by an expansion / contraction biasing portion 136 formed, for example, by a spring. Tip extension portions 132 are provided at both ends of the expandable portion 131.

[0014] The tip extensions 132 are formed in an arc shape so as to convex outward in the tire radial direction L. That is, the outer edge of the tip extensions 132 is arc-shaped. These tip extensions 132 extend in an arc shape that is biased toward the forward rotation direction of the tire portion 121A (counterclockwise rotation in FIG. 4) relative to the expandable portion 131. Therefore, when the tip extensions 132 rotate in the reverse direction while positioned at the restricting position E, they engage with the engaging portion 133, restricting the reverse rotation of the expandable portion 131, and when they rotate in the forward direction, they ride over the engaging portion 133, allowing the expandable portion 131 to continue rotating in the forward direction. Note that forward rotation means that the tire part 121A rotates in the direction in which the movable mounting part 12 rises when the main body part 11 is oriented vertically (left rotation in Figure 4), and reverse rotation means that the tire part 121A rotates in the direction in which the movable mounting part 12 descends (right rotation in Figure 4).

[0015] The engagement portion 133 is provided at the other end of the connecting portion 134 and is fixed so as not to rotate in synchronization with the rotation of the tire portion 121A and the extension / contraction portion 131. This engagement portion 133 is formed in an L-shape in a plan view. A portion of the engagement portion 133 that extends in a direction intersecting the extension direction (tire radial direction L) of the extension / contraction portion 131 when the tip extension portion 132 is disposed in a position where it engages with the engagement portion 133 at the restricted position E (as shown in FIG. 6 ) serves as a locking portion 135. At this time, the tip extension portion 132 is also disposed so as to extend in a direction intersecting the extension direction (tire radial direction L) of the extension / contraction portion 131.

[0016] With this configuration, when the movable mounting unit 12 rises relative to the main body unit 11, the tip extension 132 is disposed at the release position D by the biasing force of the expansion / contraction biasing unit 136, so that the tire unit 121A and the expansion / contraction unit 131 rotate in the reverse direction without coming into contact with the engagement unit 133. On the other hand, when the movable mounting unit 12 descends at a normal speed, the tip extension 132 is disposed at the release position D by the biasing force of the expansion / contraction biasing unit 136, so that the tire unit 121A and the expansion / contraction unit 131 rotate in the forward direction without coming into contact with the engagement unit 133. Furthermore, when the movable mounting unit 12 descends at a speed faster than normal, the tip extension 132 is disposed at the restriction position E against the biasing force of the expansion / contraction biasing unit 136 due to the centrifugal force applied by the forward rotation, and is engaged with and locked by the locking unit 135 on the outside in the tire radial direction L, so that the forward rotation of the tire unit 121A and the expansion / contraction unit 131 is restricted. From this state, when the tire portion 121A and the expansion / contraction portion 131 are rotated in the reverse direction, the engagement between the tip extension portion 132 and the lock portion 135 is released, and the tip extension portion 132 is positioned at the release position D by the biasing force of the expansion / contraction biasing portion 136.

[0017] Next, how to use the mobile scanning device 1 and the scanning device holder 10 in this embodiment will be described. FIG. 8 is an explanatory diagram showing how scanning is performed by the mobile scanning device 1. The mobile scanning device 1 scans a wall W, which is a scanning target, to acquire spatial information and the like and create drawings, 3D models, and the like. First, the user U extends the main body 11 in the longitudinal direction N to match the height of the wall W. Then, the user U moves the movable mounting part 12 to the lower end of the main body 11 and attaches the scanning device S to the holding part 122. As a result, the scanning device S is fixed to the movable mounting part 12 along the longitudinal direction N of the main body 11.

[0018] Then, the user U grasps the main body 11 at a position further below the movable mounting portion 12 and orients the main body 11 vertically. In other words, the main body 11 is positioned so that it extends parallel to the wall W. As a result, the scanning device S is also positioned parallel to the wall W. Then, the user U operates the scanning device S to start scanning. After finishing scanning the position of the wall W that the scanning device S directly faces, the scanning device S is raised. That is, the user U pulls down the outer string of the string part 142. Then, the pulley part 141 rotates, which rotates the string part 142, and the movable mounting part 12 rises.

[0019] At this time, because the tip extension portion 132 is disposed in the release position D by the biasing force of the extension / contraction biasing portion 136, the tire portion 121A rotates in the reverse direction together with the extension / contraction portion 131 in accordance with the rise of the movable mounting portion 12, guiding the rise of the movable mounting portion 12. Then, when the scanning device S finishes scanning at the raised position, the user U operates the string portion 142 in the same manner as described above to raise the movable mounting portion 12. By repeating these operations, the top and bottom surfaces of the wall W are scanned. In the above, scanning is performed in order from bottom to top, but this is not limited to this and scanning may be performed in order from top to bottom. In this case, when the user U pulls down the inner string of the string part 142, the movable mounting part 12 descends in the same manner as above. At this time, the tip extension portion 132 is positioned at the release position D due to the biasing force of the expansion / contraction biasing portion 136, so that, as described above, the tire portion 121A rotates forward together with the expansion / contraction portion 131 to guide the descent of the moving mounting portion 12.

[0020] During such a scanning operation, it is conceivable that the movable mounting part 12 may fall due to various factors such as operational error or vibration. The movable scanning device 1 and the scanning device holder 10 prevent the movable mounting part 12 from falling in the following manner. That is, as shown in FIG. 4, during normal lifting and lowering operations, the tip extension portion 132 is disposed in the release position D, allowing the extension portion 131 and the tire portion 121A to rotate. However, when the movable mounting portion 12 falls, it falls at a faster-than-normal speed. Then, as shown in FIG. 6, the extension portion 131 and the tire portion 121A rotate forward faster than normal, causing the extension portion 131 to extend due to centrifugal force against the biasing force of the extension / contraction biasing portion 136, and the tip extension portion 132 to come into contact with the inner circumferential surface of the tire portion 121A. This places the tip extension portion 132 in the restricted position E. Then, the tip extension portion 132 engages with the lock portion 135 on the outside in the tire radial direction L, thereby restricting the forward rotation of the extension portion 131 and the tire portion 121A. This prevents the movable mounting portion 12 from falling.

[0021] Furthermore, to release this restriction, the movable mounting part 12 is raised by operating the string part 142. Then, as shown in FIG. 7, the expandable part 131 rotates in the reverse direction, and the distal extension part 132 disengages from the lock part 135. Then, the expandable part 131 contracts due to the biasing force of the expandable biasing part 136, and the distal extension part 132 is placed in the release position D, as shown in FIG. 4. This allows the scanning operation to be performed normally again, as described above. When the restriction is released, even if the amount of movement that raises the movable mounting portion 12 is large and the speed is fast, if the telescopic portion 131 rotates in the reverse direction while the tip extension portion 132 is disposed in the restricted position E, as shown in Fig. 7, the outer edge of the tip extension portion 132 is formed in an arc shape, so that the tip extension portion 132 rides up the lock portion, causing the telescopic portion 131 to further rotate in the reverse direction. Therefore, when the restriction is released, the user U can release the restriction with just the simple action of lifting the movable mounting portion 12 without having to consider the amount of movement of the lift.

[0022] As described above, the mobile scanning device 1 and scanning device holder 10 of this embodiment enable rapid and accurate scanning of the scanning target in the vertical direction by the simple operation of raising and lowering the scanning device along the main body 11. Furthermore, even if the user U is in a place that is out of reach, the user U can scan by extending the main body 11. Furthermore, since the movable mounting part 12 is provided with the fall prevention part 13, even if the movable mounting part 12 is likely to fall due to some accident, the movable mounting part 12 can be prevented from falling. Furthermore, since the movable mounting part 12 is provided with the clamping part 121 and the holding part 122, the clamping part 121 can guide the vertical movement of the movable mounting part 12 while holding the scanning device.

[0023] Furthermore, since the clamping portion 121 is equipped with a rotating body and a biasing portion such as the suspension portion 121D, the biasing portion can bias the rotating body inward in the radial direction K of the main body, and the rotating body clamps the main body portion 11, making it easy to raise and lower the movable mounting portion 12. Furthermore, since the fall prevention section 13 is provided with a restricting section, the rotation of the rotating body can be restricted when the moving mounting section 12 falls, and the falling of the moving mounting section 12 can be prevented. Furthermore, since the regulating part is equipped with an extension / contraction part 131 and an engagement part 133, when the movable mounting part 12 falls, the extension / contraction part 131 is positioned in the regulating position and engages with the engagement part 133, thereby regulating the forward rotation of the rotating body and preventing the movable mounting part 12 from falling. Furthermore, since the extension / contraction section 131 is biased to be positioned at the release position D and is extended to the restriction position E by the centrifugal force generated by the rotation of the rotating body, not only can the rotation of the rotating body be restricted with a simple configuration, but when the restriction is to be released, the restriction on rotation can be released by simply performing the simple action of rotating in the reverse direction.

[0024] Furthermore, since the locking portion 135 and the tip extending portion 132 are provided, when the movable mounting portion 12 falls, the tip extending portion 132 is disposed in the restricted position E and can be engaged with the locking portion 135, making it possible not only to easily restrict rotation but also to easily release it by simply rotating it in the reverse direction. Furthermore, since the tip extending portion 132 is provided, it is possible to easily move the extendable portion 131 to the restricted position E by centrifugal force when it rotates. Furthermore, because the outer edge of the tip extension portion 132 rides up on the lock portion 135, when the restriction is released, even if the amount of movement to lift the movable mounting portion 12 is large and the speed is fast, the tip extension portion 132 rides up on the lock portion 135, allowing the extendable portion 131 to further rotate in the reverse direction. Therefore, when the restriction is released, the restriction can be released by just the simple action of lifting, without having to consider the amount of movement to lift, etc. Furthermore, because the outer edge of tip extension portion 132 is formed in an arc shape, when the restriction is released, lock portion 135 can easily ride up and reverse rotate expandable portion 131. Furthermore, when expandable portion 131 is expanded by centrifugal force, tip extension portion 132 comes into contact with the inner circumferential surface of tire portion 121A, thereby preventing expansion of expandable portion 131.

[0025] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, although the movable mounting unit 12 is described as having the clamping unit 121 and the holding unit 122, the configuration is not limited to this and can be changed as appropriate. Specifically, the movable mounting unit 12 may be raised and lowered by being suspended or supported downward. In this case, the clamping unit 121 does not need to be provided. Furthermore, although the clamping unit 121 is described as including the tire portion 121A as a rotating body and the suspension portion 121D as a biasing portion, the present invention is not limited to this and the configuration can be changed as appropriate. For example, the rotating body may be a sphere or the like in addition to the tire portion 121A. Furthermore, the biasing portion may be made of resin, electricity, magnetism, or the like in addition to the suspension portion 121D.

[0026] Furthermore, although the fall prevention unit 13 is described as having the extension / contraction unit 131 and the engagement unit 133, which are the regulating units, the present invention is not limited to this and the configuration can be changed as appropriate. For example, the speed or acceleration of the moving mounting unit 12 may be detected and the rotation of the rotating body may be regulated in accordance with the detection results, without providing the extension / contraction unit 131 and the engagement unit 133. Furthermore, the rotation may be regulated by other mechanical mechanisms, electricity, magnetism, etc. The configurations of the stretchable portion 131 and the engaging portion 133 can also be changed as appropriate. For example, the stretchable portion 131 may not stretch, but the tip portion may move back and forth in the tire radial direction L. The engaging portion 133 does not have to be L-shaped, and may be triangular, rectangular, or another polygonal shape, or any other shape. The stretchable portion 131 may be fixed and not stretchable, and the engaging portion 133 may move back and forth in the tire radial direction L.

[0027] Furthermore, although the extension / contraction biasing unit 136 is provided in the extension / contraction unit 131, this is not limiting and the configuration can be changed as appropriate. As described above, it may be made of resin, electricity, magnetism, or the like. Furthermore, the extension / contraction unit 131 may not be provided. In this case, when the restriction on rotation is to be released, the extension / contraction unit 131 may be returned to the release position D by another mechanical mechanism, electricity, magnetism, or the like. Furthermore, without providing the extension / contraction unit 131, when the restriction on rotation is to be released, the user U may manually release it. Furthermore, although the locking portion 135 and the tip extension portion 132 are provided, this is not limitative and the configuration can be changed as appropriate. For example, the locking portion 135 may be convex in a direction intersecting the tire radial direction L, and the tip extension portion 132 may be concave in the same direction, so that when restricting rotation, the convex portion of the locking portion 135 and the concave portion of the tip extension portion 132 fit together. Furthermore, the locking portion 135 and the tip extension portion 132 do not have to be provided.

[0028] Furthermore, when the tire portion 121A rotates in the reverse direction after the rotation is restricted, the tip extension portion 132 rides up over the lock portion 135; however, this is not limited to this, and the configuration can be changed as appropriate. For example, when the tire portion 121A rotates in the reverse direction, the extension portion 132 may ride up over the lock portion 135 by bending the extension portion 131, or the engagement portion 133 may move in the tire radial direction L. Furthermore, the tip extension portion 132 does not have to ride up over the lock portion 135. Furthermore, although the outer edge of the tip extension 132 is formed in an arc shape, this is not limiting and the configuration can be changed as appropriate. For example, it may be triangular, rectangular, or other polygonal or other shapes. Furthermore, although the fall prevention unit 13 is described as being provided inside the tire portion 121A, this is not limiting and the configuration can be modified as appropriate. For example, as shown in Fig. 9, the fall prevention unit 13 may be provided outside the tire portion 121A. That is, the extension unit 131 may be connected to the connecting shaft A so as to rotate in synchronization with the tire portion 121A, and the tip extension unit 132 may be engaged with the locking unit 135 in the same manner as described above. The extension unit 131 may be extended to the restriction position E by centrifugal force and stopped there.

[0029] In this embodiment, the wall W is scanned, but the scan target can be changed as appropriate. In other words, scanning refers to acquiring (sensing) information while moving relative to the scan target, and the acquired information may be temperature, concentration, indoor scan information, cracks, illuminance, sound (noise), radio waves (wifi, frequency), vibration, etc. In addition, in this embodiment, the user U scans an area above the user's feet with respect to the wall W, but this is not limited thereto, and the area below may be scanned with the main body unit 11 lowered downward from the user's feet. For example, the user U may lower the main body unit 11 from the road through a manhole or the like, and scan the area below the user's feet in the same manner as described above.

[0030] Although a smartphone is used as an example of a scanning device, the present invention is not limited to this and the configuration can be changed as appropriate. For example, a dedicated scanning device may be used. Furthermore, although the user U operates the string 142 to move the movable mounting unit 12 up and down, this is not a limitation, and the configuration can be changed as appropriate. For example, the string 142 may be rotated by operating a handle, or the string 142 may be rotated by a drive unit such as a motor. Furthermore, the movable mounting unit 12 may be configured to move up and down relative to the main body 11 without providing the string 142, pulley 141, or the like. For example, the movable mounting unit 12 may be configured to move up and down by a drive unit such as a motor. A monitor may also be provided on the main body 11. This allows the results of the scan by the scanning device S to be displayed on the monitor, allowing the user U to easily perform the scanning operation while viewing the image on the monitor.
