[0009] Hereinafter, an embodiment of the device mounting device according to the present invention will be described in detail with reference to the drawings. The X-axis, Y-axis, and Z-axis in some of the drawings are shown for the purpose of defining planes and directions in the device mounting device illustrated. The X-axis, Y-axis, and Z-axis are mutually orthogonal and form a right-handed system. In the following description, a direction parallel to the X-axis is called the X-direction, a direction parallel to the Y-axis is called the Y-direction, and a direction parallel to the Z-axis is called the Z-direction. When each of the X-direction, Y-direction, and Z-direction is associated with the direction of the arrows (positive and negative) of the X-axis, Y-axis, and Z-axis shown in the drawings, the "positive side" or "negative side" is added. In this specification, for convenience, the Z direction is sometimes referred to as the vertical direction and the Z direction as the up-down direction. In this specification, "up" and "upper" are intended to mean the positive side of the Z direction relative to a reference surface, member, position, etc., and "lower" and "lower" are intended to mean the negative side of the Z direction relative to a reference surface, member, position, etc. For example, when it is described that "a component B is placed on top of a component A," the component B is placed on the positive side of the Z direction when viewed from the component A.

[0010] The term "site" in this specification primarily refers to a construction site, but is not limited to a construction site. The term "site" may include any location where the device mounting device according to the present invention can be used to install an electronic device. For example, the "site" where an electronic device is installed may be a predetermined space in a commercial facility where many people pass by.

[0011] [First embodiment] Fig. 1 is a front view illustrating a method for installing an electronic device using a device mounting fixture according to a first embodiment. Fig. 2 is a diagram illustrating an example of a method for using an electronic device installed in a work site.

[0012] FIG. 1 shows an example in which multiple electronic devices 2 are attached to a safety tool 1 having an approximately conical outer shape, which is sometimes called a road cone or the like. The multiple electronic devices 2 are attached to the safety tool 1 by a single device mounting fixture 3. As described later with reference to FIG. 3 and the like, the device mounting fixture 3 is approximately ring-shaped, and is installed on the safety tool 1 by inserting the upper end of the safety tool 1 from below the hollow part. Each of the multiple electronic devices 2 may be capable of wireless communication, as illustrated in FIG. 2. The electronic device 2 includes an electronic device configured to be capable of wireless communication and a battery that supplies power to the electronic device, which are housed in a case. The electronic device of the electronic device 2 may be a camera 200 or a speaker 201, as illustrated in FIG. 2.

[0013] The safety tool 1 to which the electronic device 2 is attached is installed, for example, at a construction site. Fig. 2 illustrates three electronic devices 2 (2A to 2C) installed at a construction site. The first electronic device 2A and the second electronic device 2B each include a camera 200 and a battery 202 as electronic devices, and the third electronic device 2C includes a speaker 201 and a battery 202 as electronic devices.

[0014] The first electronic device 2A and the second electronic device 2B are wirelessly connected to, for example, an access point 4 installed in the site by a wireless communication device (not shown) built into the camera 200 or connected to the camera 200, and communicate with the computer 6 via a communication device such as a router 5. The third electronic device 2C is wirelessly connected to, for example, an access point 4 installed in the site by a wireless communication device (not shown) built into the speaker 201 or connected to the speaker 201, and communicates with the computer 6 via a communication device such as a router 5. The router 5 and the computer 6 may communicate via a communication network such as the Internet. Each of the first electronic device 2A, the second electronic device 2B, and the third electronic device 2C and the access point 4 are wirelessly connected according to a well-known wireless communication standard such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). Each of the first electronic device 2A and the second electronic device 2B transmits a video or image of the site captured by the camera 200 to the computer 6. The video transmitted to the computer 6 is used by the monitor 7 for monitoring the site. The third electronic device 2C receives voice data such as instructions from the supervisor 7 to the workers, and emits the received voice data as sound (sound waves) within the work site.

[0015] The camera 200 and the speaker 201 described above with reference to Fig. 2 are merely examples of electronic devices included in the electronic device 2 installed in the field. The electronic devices included in the electronic device 2 are not limited to specific electronic devices. For example, the camera 200 may be a visible light camera or a thermal camera. The electronic device 2 may include electronic devices such as a microphone (sound collection device), a thermometer, a hygrometer, a lighting device, a display device, etc.

[0016] When installing electronic equipment 2 at a site, it is desirable to satisfy requirements such as ease of installation and removal (collection), not interfering with work at the site (movement of people and objects), and not causing a sense of foreign body at the site. In order to satisfy these requirements, the equipment mounting fixture 3 according to the first embodiment is detachably installed on the safety equipment 1. Furthermore, a single equipment mounting fixture 3 may be configured to detachably mount multiple electronic equipment 2, as described later.

[0017] Fig. 3 is a perspective view illustrating an example of the external configuration of the device mounting fixture according to the first embodiment. Fig. 4 is a partially enlarged perspective view illustrating an example of a method for mounting an electronic device to the device mounting fixture.

[0018] 3 is generally annular, and is provided with four device mounting sections 310 to which the electronic device 2 can be attached. The device mounting sections 310 define a concave space that opens continuously from the upper surface 300 to the outer circumferential surface 301 of the device mounting device 3A, and can detachably accommodate the mounting sections 210 of the electronic device 2.

[0019] The mounting section 210 of the electronic device 2 includes, for example, a first section 220 having one end connected to a case that houses the electronic device and the battery 202, and a second section 221 having an arm section 223 connected to the other end side of the first section 220. The second section 221 has a disk-shaped base section 222 and an arm section 223 protruding from the circular surface of the base section 222. The first section 220 and the arm section 223 of the second section 221 are connected in a manner that allows the angle between the extension direction of the first section 220 and the extension direction of the arm section 223 to be changed and can be held at a desired angle. The method of connecting the first section 220 and the arm section 223 of the second section 221 is not limited to a specific method.

[0020] The device mounting portion 310 of the device mounting fixture 3A is configured such that the circular surface of the base portion 222 is parallel to the surface including the Z direction, and the second portion 221 of the electronic device 2 can be detachably attached through the open end of the upper surface 300. The shape of the open end of the upper surface 300 in the device mounting portion 310 is a "convex character shape" including a first rectangular portion with a dimension D1 in the first direction (X direction in FIG. 4) and a dimension W4 in the second direction (Y direction in FIG. 4), and a second portion with a dimension W1 (<W4) in the second direction that continues from the radially outer end side of the first portion to the outer periphery of the upper surface 300. The dimension D1 and the dimension W4 in the device mounting portion 310 illustrated in FIG. 4 are set such that, for example, D1≈D2 and W4≈W3 when the thickness of the disk-shaped base portion 222 in the second portion 221 of the electronic device 2 is D2 and the diameter is W3. In the second portion of the device mounting portion 310 illustrated in FIG. 4, for example, W1≈W2 when the width of the arm portion 223 in the second portion 221 of the electronic device is W2, and the arm portion 223 can enter when the base portion 222 of the second portion 221 is inserted into the first portion of the device mounting portion 310 (for example, symmetric with respect to the line with the X direction as the axis of symmetry in the plan view of the upper surface 300).

[0021] The device mounting portion 310 defines a concave section that is dug down from the upper surface 300 to a position at a depth H within the "convex character shape" open region on the upper surface 300. The depth H is smaller than the dimension in the direction (Z direction) along the depth H in the device mounting fixture 3A, and the relationship with the diameter W3 of the disk-shaped base portion 222 is set such that, for example, H≥0.5×W3, and more preferably H≥W3.

[0022] The shape of the device mounting part 310 is not limited to the shape described above with reference to Fig. 3 and Fig. 4. The shape of the device mounting part 310 may be any shape that allows the second part 221 of the electronic device 2 to be attached to and detached from the upper surface 300 of the device mounting fixture 3A and prevents the second part 221 of the electronic device 2 from being attached to and detached from the outer circumferential surface 301. Such a shape of the device mounting part 310 can facilitate the attachment and detachment of the electronic device 2 to and from the device mounting fixture 3A and can prevent the electronic device 2 from unintentionally falling off from the device mounting fixture 3A.

[0023] The material of the device mounting tool 3A is not limited to a specific material. The device mounting tool 3A may be formed of a resin material such as polyvinyl chloride resin, polyethylene resin, acrylic resin, etc. The method of forming the device mounting tool 3A illustrated in FIG. 3 is not limited to a specific method. The device mounting tool 3A can be formed, for example, by injection molding, by a 3D printer, or by cutting. The device mounting tool 3A may be formed not only of a single material, but also by combining two or more types of materials. For example, the device mounting tool 3A may have a ring shape having a plurality of device mounting parts 310 formed of a first material, and a second material may be laminated on the surface part of the device mounting part 310 of the ring shape formed of the first material. The second material may be, for example, a well-known elastic material for preventing rattling of the second part 221 of the electronic device 2 inserted into the device mounting part 310.

[0024] Fig. 5 is a diagram for explaining a more preferable example of the equipment mounting fixture according to the first embodiment. Fig. 5 illustrates a cross-sectional shape of the equipment mounting fixture 3A installed on the safety tool 1 when it is cut in half along a plane parallel to the ZX plane.

[0025] The safety tool 1 in which the equipment mounting tool 3A is installed has an outer shape that tapers upward at the portion that passes through the hollow portion of the equipment mounting tool 3A. Therefore, if the inner diameter of the equipment mounting tool 3A is constant from the upper end to the lower end, only the lower end portion of the equipment mounting tool 3A will be in contact with the safety tool 1, making it difficult to stably install the equipment mounting tool 3A on the safety tool 1 so that, for example, a desired range in the work site is captured by the camera 200. If only the lower end portion of the equipment mounting tool 3A is in contact with the safety tool 1, a change in the relative position of the equipment mounting tool 3A with respect to the safety tool 1 (specifically, a change in which the axial direction of the equipment mounting tool 3A deviates from the axial direction or vertical direction of the safety tool 1) will occur due to an external factor, and the safety tool 1 may fall over due to the change in the position of the equipment mounting tool 3A. In order to stably install the equipment mounting tool 3A, for example, as illustrated in Fig. 5, the inner circumferential surface 302 of the equipment mounting tool 3A may be changed so that the inner diameter becomes smaller from the lower end to the upper end (in other words, tapered) so as to be parallel to the side surface (generator of the cone) 102 of the safety tool 1. The equipment mounting tool 3A illustrated in Fig. 5 is installed with the entire inner circumferential surface 302 in contact with the side surface 102 of the safety tool 1, so that the equipment mounting tool 3A can be stably installed on the safety tool 1. The equipment mounting tool 3A illustrated in Fig. 5 may have a rubber sheet or the like attached to the inner circumferential surface 302 to further increase adhesion with the safety tool 1.

[0026] The equipment mounting tool 3A of the first embodiment can be easily installed on the safety tool 1 and removed from the safety tool 1. The safety tool 1 is used, for example, to clearly indicate no-entry areas within a work site and to ensure the movement of workers. Furthermore, the equipment mounting tool 3A is capable of mounting multiple electronic devices 2, and can easily mount and remove the electronic devices 2. Therefore, by using the equipment mounting tool 3A of the first embodiment, multiple electronic devices 2 can be easily installed and removed (collected).

[0027] The safety equipment 1 is placed in a place that does not interfere with work (movement of people and objects) at the site. Therefore, by using the equipment mounting fixture 3A of the first embodiment, multiple electronic devices 2 can be installed in places that do not interfere with work and without causing a sense of foreign objects at the site.

[0028] Furthermore, the device mounting tool 3A of the first embodiment allows multiple electronic devices 2 to be installed on one safety tool 1. Also, for example, by preparing device mounting tools 3A with different numbers of device mounting parts 310, a desired number of electronic devices 2 can be installed on one safety tool 1. Moreover, by standardizing the shape of the mounting parts 210 (see FIG. 4) in the electronic devices 2, multiple types of electronic devices 2 can be installed on one safety tool 1 using one device mounting tool 3A. That is, the device mounting tool 3A of the first embodiment can flexibly accommodate the installation of electronic devices other than cameras and the installation of multiple types of electronic devices on one safety tool. Therefore, by using the device mounting tool 3A of the first embodiment, multiple electronic devices 2 can be easily installed in the field.

[0029] [Second embodiment] Fig. 6 is a perspective view for explaining a configuration example of a device mounting tool according to a second embodiment. Fig. 7 is a top view of the device mounting tool illustrated in Fig. 6. Fig. 8 is a top view of a device mounting tool in which the number of mountable electronic devices is changed.

[0030] The device mounting fixture 3B illustrated in Figures 6 and 7 is obtained by dividing the device mounting fixture 3A, which has been described in the first embodiment as being formed as an integrated part, into a plurality of parts. The device mounting fixture 3B includes a first part 320 having a device mounting portion 310 formed therein, and a second part 330 having no device mounting portion 310 formed therein. The device mounting fixture 3B is formed into a substantially ring shape by joining one or more first parts 320 and one or more second parts 330 together.

[0031] The first component 320 is formed with the device mounting portion 310 described in the first embodiment, and the circumferential angle in a plan view of the upper surface 300 (the angle between a first end surface 321 located at one end in the circumferential direction and a second end surface 323 located at the other end) is smaller than 45 degrees. The first component 320 is formed with a male coupling portion 322 protruding from the first end surface 321 on the first end surface 321, and a female coupling portion 324 receding from the second end surface 323 and pairing with (fitting with) the male coupling portion 322 on the second end surface 323.

[0032] The second part 330 does not have a device mounting portion 310 formed therein, and the angle in the circumferential direction in a plan view of the upper surface 300 (the angle between a first end face 331 located at one end in the circumferential direction and a second end face 333 located at the other end) is smaller than 45 degrees. The first end face 331 of the second part 330 is an end face that faces the second end face 323 of the first part 320 when the second part 330 is combined with the first part 320 to form a ring shape, and a male coupling portion 332 that pairs with (fits with) a female coupling portion 324 formed on the second end face 323 of the first part 320 is formed thereon. The second end surface 333 of the second part 330 is an end surface that faces the first end surface 321 of the first part 320 when combined with the first part 320 to form a ring shape, and has a female joint portion 334 formed thereon that mates with (fits with) the male joint portion 322 formed on the first end surface 321 of the first part 320.

[0033] The device mounting tool 3B of the second embodiment can change the circumferential angle of the part used as the second part 330 depending on the number of first parts 320 used to form the ring shape. For example, the device mounting tool 3B shown in FIG. 6 and FIG. 7 forms a ring shape with four first parts 320 and four second parts 330. In this example, the second part 330 is selected such that the circumferential angle in the plan view of the upper surface 300 when one first part 320 and one second part 330 are joined is 90 degrees. Specifically, when the circumferential angle of the first part 320 is 70 degrees, a part with a circumferential angle of 20 degrees is selected as the second part 330. By using the device mounting device 3B illustrated in Figures 6 and 7, for example, four electronic devices 2, each including a camera 200, can be arranged so that the directions of the shooting centers of adjacent cameras 200 (the directions shown by the arrows in Figure 7) differ by 90 degrees in a planar view, thereby enabling imaging in all directions.

[0034] 8 illustrates an example of a device mounting fixture 3B in which a ring shape is formed by three first parts 320 and three second parts 330. In this example, for example, a second part 330 is selected such that a circumferential angle in a plan view of the upper surface 300 when one first part 320 and one second part 330 are joined is 120 degrees. Specifically, when the circumferential angle of the first part 320 is 70 degrees, a part with a circumferential angle of 50 degrees is selected as the second part 330.

[0035] In the device mounting fixture 3B according to the second embodiment, the combination of the number of the first parts 320 and the number of the second parts 330 used to form the ring shape is not limited to a specific combination. For example, when the circumferential angle of the first parts 320 is 70 degrees, the device mounting fixture 3B having a ring shape can be formed by five first parts 320 and one second part 330 having a circumferential angle of 10 degrees. In addition, when the circumferential angle of the first parts 320 is set to 60 degrees, the device mounting fixture 3B having a ring shape can be formed by six first parts. In addition, the device mounting fixture 3B in the second embodiment is not limited to a shape in which the inner diameter is constant from the upper end to the lower end as illustrated in Figs. 6 to 8, but may be a shape in which the inner peripheral surface is parallel to the side surface (generatrix of the cone) of the safety tool 1 to which the device mounting fixture 3B is attached, as described above with reference to Fig. 5.

[0036] The material of the first part 320 and the second part 330 in the device mounting tool 3B is not limited to a specific material. The first part 320 and the second part 330 may be formed of a resin material such as polyvinyl chloride resin, polyethylene resin, acrylic resin, etc. The method of forming the first part 320 and the second part 330 is not limited to a specific method. The first part 320 and the second part 330 can be formed by, for example, injection molding, a 3D printer, or cutting. The first part 320 and the second part 330 may be formed of the same material or different materials. For example, the first part 320 can be formed of a high-strength material that is unlikely to deform due to the weight of the electronic device 2, and the second part 330 can be formed of a material that has high adhesion to the safety tool 1.

[0037] The equipment mounting fixture 3B of the second embodiment, like the equipment mounting fixture 3A of the first embodiment, can flexibly accommodate installation of electronic devices other than a camera and installation of multiple types of electronic devices on one security tool. Therefore, by using the equipment mounting fixture 3B of the second embodiment, multiple electronic devices 2 can be easily installed on-site.

[0038] Furthermore, the device mounting tool 3B can form a ring shape by combining a plurality of parts selected from a first part 320 having a device mounting portion 310 formed therein and a second part 330 having no device mounting portion 310 formed therein. For this reason, for example, if a part of the device mounting tool 3B (for example, one of the plurality of first parts 320) is damaged, only the damaged part needs to be replaced, and the amount of material discarded due to the damage can be reduced, thereby reducing the environmental load caused by the disposal of materials.

[0039] [Third embodiment] Fig. 9 is a perspective view for explaining a first configuration example of the device mounting fixture according to the third embodiment. Fig. 10 is a top view for explaining an installation example of the device mounting fixture illustrated in Fig. 9. Fig. 11 is a top view for explaining a second configuration example of the device mounting fixture according to the third embodiment. Fig. 12 is a top view for explaining a third configuration example of the device mounting fixture according to the third embodiment.

[0040] The device mounting tool according to the third embodiment makes it possible to mount a plurality of electronic devices 2 on an object separate from the safety tool 1, such as a pillar in a work site.

[0041] 9 shows a configuration example of a device mounting tool 3C that can be used to install an electronic device 2 on an object whose outer shape is a square tube or a square prism. The device mounting tool 3C includes a first part 320 having a device mounting portion 310 formed therein, and a second part 340 having a part mounting portion 341 formed therein for mounting the first part 320. The device mounting tool 3C is formed into a square ring shape by joining four second parts 340, and the first part 320 is attached to the outer circumferential surface of the square ring shape.

[0042] The first part 320 used in the device mounting tool of the third embodiment may have the same configuration as the first part 320 described in the second embodiment. That is, the first part 320 in the device mounting tool of the third embodiment can be used as a part of the device mounting tool 3B for installing the electronic device 2 in the safety tool 1. In the following description, the surfaces of the first part 320 that become the outer peripheral surface and the inner peripheral surface when the device mounting tool 3B (see FIG. 6) is formed using the first part 320 are referred to as the outer peripheral surface and the inner peripheral surface of the first part 320, respectively, for convenience. In the following description, the surfaces of the second part 340 that become the outer peripheral surface and the inner peripheral surface when four second parts 340 are joined to form a quadrangular ring shape are referred to as the outer peripheral surface and the inner peripheral surface of the second part 340, respectively, for convenience.

[0043] 9 is a part that is one side of a square ring in a plan view of the upper surface 300, and is provided with a part attachment section 341 that defines a space that opens continuously from the upper surface 300 to the outer circumferential surface 301 and into which the first part 320 can be detachably attached. The part attachment section 341 has a shape that corresponds to (fits with) the inner circumferential surface of the first part 320, the first end surface 321 in which the male coupling section 322 is formed, and the second end surface 323 in which the female coupling section 324 is formed, and is provided with a female coupling section 342 into which the male coupling section 322 of the first part 320 is fitted, and a male coupling section 343 into which the female coupling section 324 of the first part 320 is fitted. The depth (dimension in the Z direction) of the part attachment portion 341 may be the same as the dimension in the Z direction of the first part 320 (see FIG. 9) or may be different. The dimension in the Z direction of the second part 340 is preferably larger than the depth (dimension in the Z direction) of the part attachment portion 341 as illustrated in FIG. 9, but may not be larger. The part attachment portion 341 is shaped to enable attachment and removal of the first part 320 from the upper surface 300 of the second part 340, and to prevent attachment and removal of the first part 320 from the outer peripheral surface 301. Such a shape of the part attachment portion 341 can facilitate attachment and removal of the first part 320 to the second part 340, and can prevent the first part 320 from unintentionally falling off the second part 340.

[0044] The second part 340 has a coupling part for coupling with another second part 340 formed at an end in the extension direction of the outer peripheral surface 301 in a plan view of the upper surface 300. A male coupling part 344 is formed on a first end face located at one end and facing an end face of another second part 340 to be coupled, and a female coupling part 345 is formed on a second end face located at the other end and facing an end face of another second part 340 to be coupled. The planar shape of the upper surface 300 of the second part 340 is not limited to a specific shape as long as it forms a quadrangular ring shape when four second parts 340 are coupled. In addition, the male coupling part 344 and the female coupling part 345 of the second part 340 are not limited to a shape continuous from the upper end to the lower end of the second part 340 as illustrated in FIG. 9. The male connecting portion 344 and the female connecting portion 345 in the second part 340 may be, for example, a columnar portion protruding (standing up) from the first end face in the normal direction to the first end face and a concave portion receding from the second end face in the normal direction to the second end face.

[0045] The device mounting tool 3C described above with reference to FIG. 9 can install a plurality of electronic devices 2 on the outer peripheral surface 301 of a square ring shape formed by the second part 340 by using the first part 320. That is, the device mounting tool 3C is suitable for installation on a square ring-shaped pillar 8A as illustrated in FIG. 10. Note that in FIG. 10, there is a gap between the inner peripheral surface 302 of the device mounting tool 3C and the pillar 8A, but by changing the shape of the second part 340, the inner peripheral surface 302 of the device mounting tool 3C can be brought into close contact with the outer peripheral surface of the pillar 8A. In order to stably install the device mounting tool 3C, for example, an elastic sheet such as a rubber sheet may be wrapped around the outer peripheral surface of the pillar 8A before the device mounting tool 3C is installed on the pillar 8A, or a rubber wedge may be inserted into the gap after the device mounting tool 3C is installed on the pillar 8A.

[0046] The device mounting tool according to the third embodiment may be, for example, a ring-shaped device mounting tool 3D in which the inner peripheral surface 302 of the second part 340 is circular in plan view, as shown in FIG. 11. The device mounting tool 3D illustrated in FIG. 11 is suitable for installation on a ring-shaped pillar 8B. Note that in FIG. 11, there is a gap between the inner peripheral surface of the device mounting tool 3D and the pillar 8B, but by changing the shape of the second part 340, the inner peripheral surface 302 of the device mounting tool 3D can be brought into close contact with the outer peripheral surface of the pillar 8B. In order to stably install the device mounting tool 3D, for example, an elastic sheet such as a rubber sheet may be wrapped around the outer peripheral surface of the pillar 8B before the device mounting tool 3D is installed on the pillar 8B, or a rubber wedge may be inserted into the gap after the device mounting tool 3D is installed on the pillar 8B.

[0047] The device mounting fixture according to the third embodiment may be, for example, device mounting fixture 3E in which the inner circumferential surface of second part 350, which is connected between two first parts 320, is shaped to face a corner of column 8A having a square tube shape, as shown in Fig. 12. The device mounting fixture 3E illustrated in Fig. 12 may be a modified example of device mounting fixture 3B according to the second embodiment that can be installed on column 8A.

[0048] In this way, the equipment mounting tool according to the third embodiment makes it possible to mount multiple electronic devices 2 on items in a site other than the safety tool 1 by changing the shape of the inner peripheral surface 302 in the ring shape formed by joining multiple parts. Therefore, the equipment mounting tool according to the third embodiment can flexibly respond to restrictions (limitations) on the installation locations of multiple electronic devices 2 in a site, for example. Therefore, by using the equipment mounting tool of the third embodiment, multiple electronic devices 2 can be more easily installed in a site.

[0049] In addition, the object on which the equipment mounting fixtures 3C, 3D, and 3E in the third embodiment are installed is not limited to a pillar in the work site. The equipment mounting fixtures 3C, 3D, and 3E may be installed, for example, on a beam in the work site, or on a safety tool 1 having a substantially conical outer shape as illustrated in FIG. 1 or on other safety tools 1.

[0050] The present invention is not limited to the above-described embodiment, and may be modified, substituted, or altered in various ways without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to the progress of technology or a different technology derived therefrom, the invention may be implemented using that method. Therefore, the claims cover all embodiments that may be included within the scope of the technical idea.

[0051] For example, the device mounting portion in the device mounting tool according to the present invention is not limited to the device mounting portion 310 which is a concave-shaped space that fits with the mounting portion 210 of the electronic device 2 as described above. The device mounting portion in the device mounting tool may be, for example, a convex portion that fits with a concave-shaped space formed on the electronic device 2. Furthermore, the device mounting portion in the device mounting tool may be engaged with the mounting portion 210 of the electronic device 2 in a manner that allows the electronic device 2 to be held by the device mounting tool. Therefore, the device mounting portion in the device mounting tool and the mounting portion 210 of the electronic device 2 may be detachably coupled in a manner other than the above-mentioned fitting.
