Technical Field

[0001] The present invention relates to a protective member and an electronic device.

Background Art

[0002] Conventionally, a protective member having a frame capable of supporting an object to be protected inside in a plan view has been known. Such a protective member is used as a protective case (protective container) for electronic devices such as smartphones, tablets, notebook PCs (Personal Computers), game machines, etc., or as a picture frame or the like for protecting pictures and books with the object to be protected.

[0003] As the above protective member, one having a frame including a plurality of columnar members and a plate-like member disposed inside the frame has been disclosed (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the protective member described in Patent Document 1, the plurality of columnar members are each fixed to the plate-like member, and the plurality of columnar members are not fixed to each other. Therefore, the frame is likely to be deformed, and there is room for improvement in the toughness of the protective member.

[0005] An object of the present invention is to provide a protective member having excellent toughness.

The frame includes a plurality of columnar members serving as sides of the frame and a connecting member connecting the plurality of columnar members to each other. Furthermore, the connecting member fixes the columnar member by sandwiching at least a portion of the columnar member between a part of the screw member including the threaded portion and the screw head and the connecting member, and the columnar member is provided with a through hole including a counterbore, the depth of the counterbore is equal to or greater than the height of the screw head. .

[0009] Hereinafter, protective members and electronic devices according to embodiments of the present invention will be described in detail with reference to the drawings. However, the embodiments shown below are illustrative examples of protective members and electronic devices that embody the technical concept of this embodiment and are not limited thereto. Furthermore, the dimensions, materials, shapes, relative arrangements, etc. of the components described in the embodiments are not intended to limit the scope of the present invention to those described therein, unless otherwise specified, but are merely illustrative examples. Note that the size, positional relationships, etc. of the components shown in each drawing may be exaggerated for clarity of explanation. In addition, in the following description, the same name and reference numerals indicate the same or similar components, and detailed explanations will be omitted as appropriate.

[0010] In the figures of this specification, directions may be indicated by the X, Y, and Z axes. The X direction along the X axis indicates a predetermined direction within the frame plane. The frame plane refers to the plane containing the frame of the protective member according to the embodiment. The Y direction along the Y axis indicates a direction perpendicular to the X direction within the frame plane. The Z direction along the Z axis indicates a direction perpendicular to both the X and Y directions. The Z direction corresponds to the normal direction of the frame plane. In this specification, a plan view means viewing the object from the Z direction.

[0011] In the X direction, the direction the arrow is pointing is denoted as the +X direction, and the opposite direction is denoted as the -X direction. In the Y direction, the direction the arrow is pointing is denoted as the +Y direction, and the opposite direction is denoted as the -Y direction. In the Z direction, the direction the arrow is pointing is denoted as the +Z direction, and the opposite direction is denoted as the -Z direction. However, these do not restrict the orientation of the protective components and electronic devices when in use; the orientation of the protective components and electronic devices when in use is arbitrary.

[0012] [First Embodiment] (Example of the overall configuration of electronic device 1) Figure 1 is an exploded perspective view illustrating the overall configuration of the electronic device 1 according to the embodiment. The electronic device 1 includes an object to be protected 2 and a protective member 3. Figure 1 shows the object to be protected 2 and the protective member 3 in a disassembled state, in other words, the protective member 3 in a state removed from the object to be protected 2.

[0013] The operator of the electronic device 1 can attach the protection member 3 to the object to be protected 2 by moving the object to be protected 2 in the direction indicated by the dashed arrow in FIG. 1 and then fitting the object to be protected 2 inside the protection member 3.

[0014] The object to be protected 2 includes a screen 20 capable of displaying images. The object to be protected 2 is, for example, an electronic blackboard. An electronic blackboard is a blackboard-shaped electronic device that can electronically convert the content drawn on the blackboard. However, the color of the electronic blackboard is not limited to black and can be any color. The electronic blackboard can also be called a whiteboard, a copyboard, etc.

[0015] The object to be protected 2 is not limited to an electronic blackboard and may be an electronic device such as a smartphone, a tablet, a PDA (Personal Digital Assistant), a notebook PC, a game machine, etc. Alternatively, the object to be protected 2 may be an article other than an electronic device such as a painting or a book.

[0016] The protection member 3 is a member for protecting the object to be protected 2. In the present embodiment, the protection member 3 is a protective case that is attached to an electronic device to protect the electronic device such as an electronic blackboard, or in other words, a protective container. However, the protection member 3 may be a frame for housing these to protect a painting, a book, etc.

[0017] The operator of the electronic device 1 brings the tip of an electronic pen capable of generating an electric field by applying a current close to the electronic blackboard as the object to be protected 2 with the protection member 3 interposed therebetween. The operator of the electronic device 1 can perform operations on the electronic blackboard such as drawing letters and figures on the electronic blackboard by moving the tip of the electronic pen so that the tip of the electronic pen draws letters and figures, using the electric field generated from the electronic blackboard. However, the operation method of the electronic blackboard is not limited to the method using an electronic pen and the electric field utilization method, and other methods may be used.

[0018] (Example of the overall configuration of the protection member 3) An example of the overall configuration of the protective member 3 will be described with reference to Figures 2 to 6. Figures 2 to 4 are diagrams illustrating the overall configuration of the protective member 3, with Figure 2 being a front view, Figure 3 a side view, and Figure 4 a rear view. Figure 5 is a cross-sectional view along the VV cutting line in Figure 2.

[0019] As shown in Figures 2 to 5, the protective member 3 comprises a frame 31, a plate-shaped member 32, an elastic member 33, and a plurality of mounting mechanisms 34 (see Figure 4). Since the frame 31 is covered by the elastic member 33, the frame 31 is shown with a dashed line in Figure 2.

[0020] The frame 31 is a frame-shaped member capable of supporting the object to be protected 2 from the inside in a plan view. The frame 31 includes a plurality of columnar members 311 and a plurality of connecting members 312. In this embodiment, since the electronic blackboard, which is the object to be protected 2, has a substantially rectangular shape in a plan view, the shape of the frame 31 in a plan view is substantially rectangular to match this. However, the shape of the frame 31 in a plan view may be circular, elliptical, polygonal, etc., to match the object to be protected 2.

[0021] Each of the multiple columnar members 311 is a member that forms an edge of the frame 31. The multiple columnar members 311 include columnar member 311a, columnar member 311b, columnar member 311c, and columnar member 311d.

[0022] Columnar members 311a and 311c each extend in the Y direction. The lengths of columnar members 311a and 311c in the Y direction are approximately equal. Columnar members 311b and 311d each extend in the X direction. The lengths of columnar members 311b and 311d in the X direction are approximately equal. The lengths of columnar members 311a and 311c in the Y direction are longer than the lengths of columnar members 311b and 311d in the X direction.

[0023] Each of the multiple columnar members 311 connects to the other multiple columnar members 311. The multiple connecting members 312 include connecting member 312a, connecting member 312b, connecting member 312c, and connecting member 312d.

[0024] The connecting member 312a connects columnar member 311a and columnar member 311d. The connecting member 312b connects columnar member 311a and columnar member 311b. The connecting member 312c connects columnar member 311b and columnar member 311c. The connecting member 312d connects columnar member 311c and columnar member 311d.

[0025] The plate-shaped member 32 is positioned so that at least a portion of it overlaps with the frame 31 in a plan view, and is fixed to the frame 31. In this embodiment, as an example, the plate-shaped member 32 is positioned so that it completely overlaps with the frame 31 in a plan view.

[0026] In the frame 31, since multiple columnar members 311 are connected to each other by connecting members 312, the frame 31 is less prone to deformation compared to the case where multiple columnar members are fixed to a plate-like member and are not connected to each other. As a result, in this embodiment, a robust protective member 3 can be provided. Furthermore, the electronic device 1 can enhance the protection of the object to be protected 2 by having a robust protective member 3.

[0027] There are no particular restrictions on the material of the plate-shaped member 32, and the plate-shaped member 32 can be made up of, for example, glass material or resin material. In order to make the plate-shaped member 32 lighter and less prone to breakage, the plate-shaped member 32 may be made up of resin material. In this embodiment, the plate-shaped member 32 is, as an example, an acrylic plate containing acrylic resin (PMMA: Polymethyl methacrylate) as its material.

[0028] The plate-shaped member 32 may be translucent. Translucency here means that the transmittance to visible light is at least 60%. Visible light refers to electromagnetic waves with wavelengths visible to the human eye. The lower limit of the wavelength range is approximately 360 nm to 400 nm. The upper limit of the wavelength range is approximately 760 nm to 830 nm.

[0029] In this embodiment, the plate-shaped member 32 is positioned to face the screen 20 (see Figure 1) of the object to be protected 2, which is supported by the frame 31. Since the plate-shaped member 32 is translucent, the operator of the electronic device 1 can operate the object to be protected 2 while viewing the screen 20 of the object to be protected 2, to which the protective member 3 is attached, through the plate-shaped member 32. However, the plate-shaped member 32 does not necessarily have to be translucent.

[0030] The elastic member 33 is a frame-shaped elastic member that supports the frame 31 from the inside in a plan view. The elastic member 33 has a rectangular frame shape in a plan view. The elastic member 33 is capable of supporting the frame 31 from the inside.

[0031] As shown in Figure 5, in this embodiment, the elastic member 33 has a first groove 331 and a second groove 332 formed on its inner surface. The elastic member 33 supports the frame 31 inward by inserting a portion of the columnar member 311b in the frame 31 into the first groove 331. The elastic member 33 also supports the plate-shaped member 32 inward by inserting the plate-shaped member 32, which is fixed to the frame 31, and a portion of the columnar member 311b in the frame 31, together into the second groove 332.

[0032] Within the second groove 332, an air layer 332a is provided between the columnar member 311b and the elastic member 33. If the air layer 332a were not provided, when an impact is applied to the elastic member 33 from the +Y direction, the columnar member 311b within the second groove 332 would receive this impact. This impact would be transmitted through the columnar member 311b to the object to be protected 2, affecting the object to be protected 2. By providing the air layer 332a, the air layer 332a can absorb the impact applied to the elastic member 33 from the +Y direction. This reduces the impact received by the columnar member 311b and the object to be protected 2.

[0033] There are no particular restrictions on the material of the elastic member 33, and it can be appropriately changed depending on the application, material, etc. of the object to be protected 2. From the viewpoint of improving the weather resistance or shock absorption of the elastic member 33, the elastic member 33 may be composed of ethylene propylene rubber. Also, from the viewpoint of improving the weather resistance or shock absorption of the elastic member 33, the hardness of the elastic member 33 may be 50 degrees or less.

[0034] In this embodiment, by supporting the frame 31 inside the elastic member 33 in a plan view, the impact on the protective member 3 due to the electronic device 1 falling or colliding can be absorbed by the elastic member 33, thereby suppressing damage to the object to be protected 2 and deformation of the frame. Furthermore, in this embodiment, by supporting the plate-shaped member 32 fixed to the frame 31 with the elastic member 33, it is possible to suppress the plate-shaped member 32 from lifting up relative to the frame 31 or from being damaged.

[0035] As shown in Figure 4, each of the multiple mounting mechanisms 34 is a mechanism for attaching the object to be protected 2 inside the frame 31. The multiple mounting mechanisms 34 include mounting mechanism 34a, mounting mechanism 34b, mounting mechanism 34c, mounting mechanism 34d, mounting mechanism 34e, and mounting mechanism 34f. Mounting mechanisms 34a and 34b are provided on the columnar member 311a. Mounting mechanism 34c is provided on the columnar member 311b. Mounting mechanisms 34d and 34e are provided on the columnar member 311c. Mounting mechanism 34f is provided on the columnar member 311d.

[0036] (Example of the configuration of the columnar member 311a) Referring to Figure 6, an example of the configuration of multiple columnar members 311 will be described. Figure 6 is an example of columnar member 311a. Note that columnar member 311c has the same configuration as columnar member 311a. Columnar members 311b and 311d have the same configuration as columnar member 311a, except that their lengths in the longitudinal direction are different. Here, columnar member 311a will be described as a representative example.

[0037] As shown in Figure 6, the columnar member 311a has a first plate-like portion 11, a second plate-like portion 12, a third plate-like portion 13, and a fourth plate-like portion 14. The first plate-like portion 11 includes a first facing portion 110. The first facing portion 110 is a surface provided to face the outer surface of the plate-like member 32 fixed to the frame 31. The first facing portion 110 will be described separately with reference to Figure 9.

[0038] The columnar member 311a includes a hollow portion 10 in a cross-section perpendicular to the direction in which it extends (in this case, the Y direction). The columnar member 311a also has a shape in which a first plate-like portion 11, a second plate-like portion 12, a third plate-like portion 13, and a fourth plate-like portion 14 are connected via a first bent portion 11a to a third bent portion 13a.

[0039] The first plate-like portion 11 is connected to the second plate-like portion 12 via the first bent portion 11a. The second plate-like portion 12 is connected to the third plate-like portion 13 via the second bent portion 12a. The third plate-like portion 13 is connected to the fourth plate-like portion 14 via the third bent portion 13a. The hollow portion 10 refers to the space enclosed on three sides by the second plate-like portion 12, the third plate-like portion 13, and the fourth plate-like portion 14.

[0040] Because the columnar member 311a has such a cross-sectional shape, its volume can be reduced, making it lighter than a block-shaped columnar member whose cross-sectional shape perpendicular to the direction in which the columnar member extends is rectangular or the like. Furthermore, a frame 31 composed of multiple columnar members 311 including the columnar member 311a can be lighter than a frame 31 composed of multiple block-shaped columnar members whose cross-sectional shape perpendicular to the direction in which the columnar member extends is rectangular or the like.

[0041] The second plate-like portion 12 has a plurality of through holes 313, including through holes 313a and 313b. Each of the through holes 313a and 313b includes a counterbore. A counterbore is a blind hole with a diameter larger than the diameter of the through hole, formed at a predetermined depth from the surface of the through hole in the member, to prevent the screw head or bolt head from protruding from the surface of the member when a screw member is inserted into the through hole formed in the member. The depth of the blind hole in the counterbore is called the counterbore depth.

[0042] The through holes 313a and 313b are used to connect the columnar member 311a to the connecting member 312a, which is used to connect the columnar member 311a and the columnar member 311d.

[0043] In this embodiment, since a countersunk screw is used as the connecting member that joins the connecting member 312a and the columnar member 311a, the counterbores in the through holes 313a and 313b are countersunk. However, the counterbores in the through holes 313a and 313b are not limited to countersunk, but may be flat counterbores or the like depending on the screw member used. Also, the number of through holes 313 is not limited to two.

[0044] The columnar member 311a may, for example, be made of aluminum and can be manufactured by die casting. The columnar member 311a is, for example, an aluminum frame. By manufacturing the columnar member 311a using such materials and methods, the strength and rigidity of the frame 31 can be ensured to a high degree. However, the shape, material, and manufacturing method of the columnar member 311a are not limited to those described above and can be appropriately changed depending on the type of object to be protected 2, etc.

[0045] (Example of the configuration of connecting member 312a) Referring to Figure 7, an example of the configuration of multiple connecting members 312 will be described. Figure 7 is a diagram illustrating the configuration of connecting member 312a. Connecting members 312b, 312c, and 312d have the same configuration as connecting member 312a. Here, connecting member 312a will be described as a representative example.

[0046] As shown in Figure 7, the connecting member 312a includes a first beam portion 21, a second beam portion 22, a second facing portion 23, and a connecting portion 24.

[0047] The first beam section 21 is a portion that extends in the Y direction, which is an example of a predetermined direction. The second beam section 22 is a portion that extends in the X direction, which is an example of a direction that intersects the predetermined direction. The connecting section 24, which is enclosed by a circle indicated by a dashed line, is the portion that connects the first beam section 21 and the second beam section 22.

[0048] The second facing portion 23 is a surface provided so as to face the outer surface of the plate-shaped member 32 fixed to the frame 31. This second facing portion 23 will be described separately with reference to Figure 10.

[0049] The first beam section 21 and the second beam section 22 have a plurality of screw holes 314, including screw holes 314a, screw holes 314b, screw holes 314c, and screw holes 314d.

[0050] Each of the screw holes 314a and 314b can be coupled in pairs to two screw members used to fix the columnar member 311a to the first beam 21. Each of the screw holes 314c and 314d can be coupled in pairs to two screw members used to fix the columnar member 311d to the second beam 22.

[0051] The connecting member 312a includes sheet metal as its material and can be manufactured by cutting and bending sheet metal. The hardness of the connecting member 312a, which includes sheet metal, is higher than that of the columnar member 311a, which includes aluminum. As a result, in this embodiment, deformation of the screw hole can be suppressed when the screw member is connected to the screw hole 314. However, the shape, material, and manufacturing method of the connecting member 312a are not limited to those described above and can be appropriately changed depending on the type of object to be protected 2, etc.

[0052] (Example of configuration around connecting member 312a) Referring to Figures 8 to 13, an example of the configuration around connecting member 312a will be explained. Note that the configurations around connecting members 312b, 312c, and 312d are the same as the configuration around connecting member 312a. Here, the configuration around connecting member 312a will be explained as a representative example.

[0053] Figure 8 is a magnified view of area VIII in Figure 2. Figure 9 is a cross-sectional view along the IX-IX cutting line in Figure 8. Figure 10 illustrates the state with the plate-like member 32 removed from Figure 8. Figure 11 illustrates the state with multiple adhesive members 35 removed from Figure 10. Figure 12 is a perspective view of Figure 11 from the front. Figure 13 is a perspective view of Figure 11 from the back.

[0054] As shown in Figure 8, the plate-shaped member 32 is fixed to the +Z-direction side surface of the columnar members 311a and 311d in the frame 31.

[0055] The plate-shaped member 32 includes a chamfered corner 321. The second facing portion 23 of the connecting member 312a faces the corner 321. By including the corner 321, the plate-shaped member 32 has no sharp parts. As a result, in this embodiment, if the electronic device 1 is dropped, damage to the plate-shaped member 32 due to sharp parts hitting the ground or the like can be avoided. In addition, in this embodiment, the presence of the second facing portion 23 allows the corner 321 of the plate-shaped member 32 to be protected by the second facing portion 23.

[0056] As shown in Figure 9, a screw member 315a, which is an example of a connecting member, includes a threaded portion 51 and a screw head 52. A counterbore 130 is formed on the upper surface of the through hole 313a, i.e., the surface on the +Z direction side. In this embodiment, the length of the depth d of the counterbore 130 and the length of the height h of the screw head 52 are approximately equal. For this reason, in Figure 9, the sign for the height h is shown in parentheses alongside the sign for the depth d.

[0057] The length of the depth d should be greater than or equal to the length of the height h. By making the length of the depth d greater than or equal to the length of the height h, the screw head 52 will not protrude from the surface of the plate-shaped member 32. In this embodiment, this prevents the screw head 52 protruding from the surface of the columnar member 311a from contacting the plate-shaped member 32 and causing stress on the plate-shaped member 32.

[0058] The connecting member 312a fixes the columnar member 311a by sandwiching at least a portion of the columnar member 311a between a portion of the screw member 315a and the connecting member 312a.

[0059] More specifically, when the threaded portion 51 of the screw member 315a is inserted into the through hole 313a, the second plate-shaped portion 12, which is part of the columnar member 311a, is sandwiched between the screw head 52, which is part of the screw member 315a, and the connecting member 312a. In this state, the threaded portion 51 of the screw member 315a is screwed into the screw hole 314a, tightening by sandwiching the second plate-shaped portion 12 between the screw head 52 and the connecting member 312a. As a result, the columnar member 311a is fixed to the connecting member 312a.

[0060] In this embodiment, the connecting member 321a is pressed by the screw member 315a, so unlike when the plate-shaped member is pressed by the screw member, no stress is applied to the plate-shaped member 32. As a result, in this embodiment, damage to the plate-shaped member 32 due to stress applied from the screw member or the like can be avoided.

[0061] As shown in Figure 9, the adhesive member 35a includes a first adhesive surface 351 and a second adhesive surface 352. The first adhesive surface 351 is the surface that adheres to the plate-shaped member 32. The second adhesive surface 352 is the surface that adheres to the columnar member 311a. The adhesive member 35a is, as an example, double-sided tape.

[0062] The first adhesive surface 351 is adhered to the -Z direction side of the plate-shaped member 32. The second adhesive surface 352 is adhered to the +Z direction side of the columnar member 311a. As a result, the adhesive member 35a can fix the columnar member 311a and the plate-shaped member 32 by adhesive. Similarly, the adhesive member 35b also includes the first adhesive surface 351 and the second adhesive surface 352, and can fix the plate-shaped member 32 to the columnar member 311d by adhesive.

[0063] The adhesive member 35a is positioned to face the upper surface 52a of the screw head 52 inserted into the counterbore 130. The upper surface 52a of the screw head 52 on the screw member 315a is bonded to the second adhesive surface 352 of the adhesive member 35a. In this embodiment, by bonding the upper surface 52a of the screw head 52 to the adhesive member 35a, it is possible to prevent the screw member 315a from rotating and loosening.

[0064] In Figure 10, the removed plate-shaped member 32 is shown by a dashed line. As shown in Figure 10, the multiple adhesive members 35 include adhesive member 35a and adhesive member 35b. Adhesive member 35a is provided on the +Z direction side surface of the columnar member 311a. Adhesive member 35d is provided on the +Z direction side surface of the columnar member 311d.

[0065] The adhesive member 35a is provided along the entire longitudinal direction of the columnar member 311a, i.e., the Y direction. Providing it along the entire longitudinal direction of the columnar member 311a means that the adhesive member 35a is provided throughout the columnar member 311a, from the end on the +Y direction side to the end on the -Y direction side. However, there may be localized areas in the longitudinal direction of the columnar member 311a where the adhesive member 35a is missing.

[0066] By using adhesive member 35a to fix the plate-shaped member 32 to the columnar member 311a along its entire longitudinal direction, the columnar member 311a and the plate-shaped member 32 can mutually reinforce each other. As a result, in this embodiment, a high level of reinforcement strength of the frame 31 by the plate-shaped member 32 can be ensured.

[0067] The adhesive member 35d is provided along the entire longitudinal direction of the columnar member 311d, i.e., the X direction. Providing it along the entire longitudinal direction of the columnar member 311d means that the adhesive member 35d is provided throughout the columnar member 311d, from the end on the +X direction side to the end on the -X direction side. However, there may be localized areas in the longitudinal direction of the columnar member 311d where the adhesive member 35d is missing. The function of the adhesive member 35d is the same as that of the adhesive member 35a.

[0068] As shown in Figures 8 and 10, in this embodiment, the outer surface 320 of the plate-shaped member 32 is positioned inward from the outer edge 310 of the frame 31. In other words, in a plan view, the plate-shaped member 32 is positioned inward from the outer edge of the frame 31. As a result, in the event that the electronic device 1 is dropped, the frame 31 will hit the floor or the like before the plate-shaped member 32, thus protecting the plate-shaped member 32 in this embodiment.

[0069] As shown in Figure 9, an air layer 111 is provided between the first facing portion 110 and the outer surface 320 of the plate-shaped member 32.

[0070] In this embodiment, the protection of the plate-shaped member 32 can be enhanced by providing the first facing portion 110 facing the outer surface 320 of the plate-shaped member 32. Furthermore, in this embodiment, the presence of an air layer 111 between the first facing portion 110 and the outer surface 320 of the plate-shaped member 32 allows the columnar member 311a to deform before colliding with the plate-shaped member 32 in the event that the electronic device 1 is dropped, thereby absorbing a portion of the impact energy. This suppresses the impact on the plate-shaped member 32 and further enhances its protection.

[0071] As shown in Figures 11 to 13, the multiple screw members 315 include screw member 315a, screw member 315b, screw member 315c, and screw member 315d.

[0072] The connecting member 312a is connected to the -Y direction end of the columnar member 311a by screw members 315a and 315b. The connecting member 312a is also connected to the -X direction end of the columnar member 311d by screw members 315c and 315d. By being connected to both the columnar member 311a and the columnar member 311d, the connecting member 312a connects the columnar member 311a and the columnar member 311d.

[0073] (Example of the configuration of mounting mechanism 34b) Referring to Figure 14, an example of the configuration of multiple mounting mechanisms 34 will be described. Figure 14 is a diagram illustrating the configuration of mounting mechanism 34b. Note that mounting mechanisms 34a, 34c, 34d, 34e, and 34f have the same configuration as mounting mechanism 34b. Here, the configuration of mounting mechanism 34b will be described as representative.

[0074] As shown in Figure 14, the mounting mechanism 34b includes a gripping portion 341, a shaft portion 342, and an engaging portion 343. As described with reference to Figure 4, the mounting mechanism 34b is provided on the frame 31.

[0075] The gripping portion 341 is attached to one end of the cylindrical shaft portion 342. The operator of the electronic device 1 can rotate the shaft portion 342 around its cylindrical axis by gripping the gripping portion 341 and manually rotating the gripping portion 341.

[0076] The engaging portion 343 is formed at the other end of the shaft portion 342 and has a rectangular shape, or in other words, an anisotropic shape, when viewed from the direction of the cylindrical axis of the shaft portion 342. The engaging portion 343 is rotatable around the cylindrical axis of the shaft portion 342 as the shaft portion 342 rotates.

[0077] With the gripping portion 341 not attached to one end of the shaft portion 342, the engaging portion 343 is positioned inside the frame 31, and the shaft portion 342 is inserted from one end into the through hole provided in the third plate-shaped portion 13 of each of the multiple columnar members 311. Subsequently, the gripping portion 341 is attached to one end of the shaft portion 342.

[0078] On the outside of the object to be protected 2, when the object to be protected 2 is positioned inside the frame 31, an engagement hole is provided at a position corresponding to the position of the engagement portion 343 in the mounting mechanism 34b, and is rectangular in shape, in other words, has an anisotropic shape that can engage with the engagement portion 343.

[0079] When the operator of the electronic device 1 places the object to be protected 2 inside the frame 31, they insert the engaging portion 343 into the engaging hole. The operator of the electronic device 1 then uses the gripping portion 341 to rotate the engaging portion 343 around the cylindrical axis of the shaft portion 342. This utilizes the anisotropy of the engaging portion 343 and the engaging hole to prevent the engaging portion 343 from being removed from the engaging hole.

[0080] The same operation described above is performed on each of the multiple mounting mechanisms 34 in the protective member 3, thereby supporting the object to be protected 2 on the protective member 3.

[0081] [Second Embodiment] In this embodiment, the columnar member 311a is fixed to the connecting member 312a by utilizing the connection between the screw member and the nut member. The configuration and operation other than this point are the same as in the first embodiment.

[0082] Figure 15 is a perspective view illustrating the configuration around the nut member 316 according to the second embodiment. Figure 15 shows a partially enlarged view of the region corresponding to region XV in Figure 13.

[0083] As shown in Figure 15, a nut member 316 is provided on the columnar member 311d. The nut member 316 is located on the opposite side of the connecting member 312a from the screw head 52 (see Figure 9).

[0084] In the first embodiment, the screw member 315a is connected to a screw hole 314a provided in the connecting member 312a, whereas in this embodiment, the screw member 315a is connected to a nut member 316. The connecting member 312a has a through hole formed therein for inserting the threaded portion 51 of the screw member 315a, instead of the screw hole 314a in the first embodiment.

[0085] In this embodiment, the nut member 316 and the threaded portion 51 are joined together, and the columnar member 311a can be fixed by sandwiching the second plate-shaped portion 12 of the columnar member 311a between the screw head 52 and the connecting member 312a and tightening the screws.

[0086] For example, in a configuration where a screw member 315a is connected to a screw hole 314a formed in a connecting member 312a, the positional relationship between columnar members 311a and 311d, with the connecting member 312a in between, depends on the positional accuracy of the screw hole 314a. If the positional accuracy of the screw hole 314a is low, the positional relationship between columnar members 311a and 311d will deviate from the desired state. As a result, it may become difficult to connect multiple columnar members 311 together using the connecting member, making it difficult to construct the frame 31.

[0087] In this embodiment, the columnar member 311a is fixed to the connecting member 312a by utilizing the connection between the screw member 315a and the nut member 316, so a through hole should be formed in the connecting member 312a. By making the diameter of the through hole larger than the diameter of the threaded portion 51 of the screw member 315a, it becomes possible to finely adjust the positional relationship between the columnar member 311a and the columnar member 311d fixed to the connecting member 312a. As a result, it becomes easier to connect multiple columnar members 311 with the connecting member 312a in between, and the frame 31 can be easily constructed.

[0088] Other effects are the same as in the first embodiment.
