DESCRIPTION OF EMBODIMENTS

[0020] The present disclosure is schematically explained below.

[0021] A supporting material according to a first configuration is a supporting material including a plate-shaped portion that supports an electronic apparatus, in a packaged state, wherein the plate-shaped portion has holes that receives a plurality of leg portions provided on a bottom surface of the electronic apparatus, and a thickness dimension of the plate-shaped portion and a depth dimension of the holes are equal to or larger than a protrusion dimension of the leg portions from the bottom surface.

[0022] According to the configuration, the supporting material having the plate-shaped portion that supports the electronic apparatus in the packaged state has the holes that receives the plurality of leg portions provided on the bottom surface of the electronic apparatus. The depth dimension of the holes is equal to or larger than the protrusion dimension of the leg portions from the bottom surface. Thus, the bottom surface of the electronic apparatus is supported in contact with the plate-shaped portion. Accordingly, a load is hardly applied to the leg portions, and deformation of the leg portions can be suppressed.

[0023] In a second configuration according to the first configuration, the holes are through holes penetrating in a thickness direction of the plate-shaped portion.

[0024] According to the configuration, since the holes are the through holes penetrating in the thickness direction of the plate-shaped portion, the holes can be easily formed at low cost.

[0025] In a third configuration according to the first configuration, the holes are non-through holes that do not penetrate in a thickness direction of the plate-shaped portion.

[0026] According to the configuration, since the holes are the non-through holes that do not penetrate in the thickness direction of the plate-shaped portion, the thickness of the plate-shaped portion can be ensured, and the rigidity of the plate-shaped portion can be improved.

[0027] In a fourth configuration according to the first configuration, the plate-shaped portion is formed using a cardboard.

[0028] According to the configuration, since the plate-shaped portion is formed using the cardboard, a predetermined impact cushioning effect can be obtained by the plate-shaped portion.

[0029] This configuration may be dependent from not only the first configuration but also the second or third configuration.

[0030] In a fifth configuration according to the first configuration, a plurality of cushioning materials are provided on a surface of the plate-shaped portion opposite to a surface supporting the electronic apparatus. The cushioning material reduces impact.

[0031] According to the configuration, since the plurality of cushioning materials are provided on the surface of the plate-shaped portion opposite to the surface supporting the electronic apparatus, an appropriate impact cushioning effect can be obtained. Further, due to the functions and effects of the first configuration, the degree of freedom in arrangement of the cushioning materials is improved, and the cushioning materials can be easily arranged. In particular, the cushioning materials can be arranged at desired positions without being affected by the layout of the leg portions.

[0032] This configuration may be dependent from not only the first configuration but also any one of the second to fourth configurations.

[0033] In a sixth configuration according to the fifth configuration, the holes are through holes penetrating in a thickness direction of the plate-shaped portion, and part of the plurality of cushioning materials are at positions overlapping at least part of a plurality of the holes in a plan view of the plate-shaped portion.

[0034] According to the configuration, since the holes are the through holes penetrating in the thickness direction of the plate-shaped portion, the holes can be easily formed at low cost.

[0035] In addition, since part of the plurality of cushioning materials are located at the positions overlapping at least part of the plurality of holes in the plan view of the plate-shaped portion, at least part of the plurality of leg portions can be supported by the cushioning materials when the electronic apparatus receives drop impact. That is, the impact can be received by both the cushioning materials and the leg portions.

[0036] A seventh configuration according to the fourth configuration further includes a plurality of cushioning materials provided on a surface of the plate-shaped portion opposite to a surface supporting the electronic apparatus, wherein each of the plurality of cushioning materials is formed using cardboard. The cushioning materials reduces impact.

[0037] According to the configuration, since the plurality of cushioning materials are provided on the surface of the plate-shaped portion opposite to the surface supporting the electronic apparatus, an appropriate impact cushioning effect can be obtained. Further, due to the functions and effects of the first configuration, the degree of freedom in arrangement of the cushioning materials is improved, and the cushioning materials can be easily arranged. In particular, the cushioning materials can be arranged at desired positions without being affected by the layout of the leg portions.

[0038] Furthermore, since the plate-shaped portion and the cushioning materials are each formed using cardboard, the plate-shaped portion and the cushioning materials can be regarded as a cushioning material as a whole. Therefore, design of impact cushioning is easier. In addition, the plate-shaped portion is regarded as a part of the cushioning material, and thus the entire thickness dimension when the cushioning material is provided in addition to the plate-shaped portion can be suppressed, which contributes to suppression of the height dimension of the entire packaged article.

[0039] In an eighth configuration according to the first configuration, the plate-shaped portion has a size that covers the electronic apparatus in a plan view.

[0040] According to the configuration, since the plate-shaped portion has the size that covers the electronic apparatus in the plan view, the electronic apparatus can be appropriately supported.

[0041] The configuration may be dependent from not only the first configuration but also any one of the second to sixth configurations.

[0042] A packaged article according to a ninth configuration includes an electronic apparatus having a plurality of leg portions on a bottom surface thereof, a supporting material that supports the electronic apparatus, in a packaged state, a cushioning material that cushions impact applied to the electronic apparatus, and a packaging box in which the electronic apparatus, the supporting material, and the cushioning material are housed, wherein the supporting material has a plate-shaped portion, the plate-shaped portion has holes that receives the plurality of leg portions provided on the bottom surface of the electronic apparatus, and a thickness dimension of the plate-shaped portion and a depth dimension of the holes are equal to or larger than a protrusion dimension of the leg portions from the bottom surface.

[0043] According to the configuration, the supporting material having the plate-shaped portion that supports the electronic apparatus in the packaged article has the holes that receives the plurality of leg portions provided on the bottom surface of the electronic apparatus. The depth dimension of the holes are equal to or larger than the protrusion dimension of the leg portions from the bottom surface. Thus, the bottom surface of the electronic apparatus is supported in contact with the plate-shaped portion. Accordingly, a load is hardly applied to the leg portions, and deformation of the leg portions can be suppressed.

[0044] In the configuration, the supporting material of any one of the second to sixth configurations may be provided instead of the supporting material of the first configuration. According to the configuration, the functions and effects of any one of the second to eighth configurations described above can be obtained in the packaged article.

[0045] In the packaged article according to the ninth configuration, since the thickness dimension of the plate-shaped portion is equal to or larger than the protrusion dimension of the leg portions from the bottom surface, the leg portions are unlikely to protrude from the plate-shaped portion. Therefore, when the cushioning materials are provided on the surface of the plate-shaped portion opposite to the surface supporting the electronic apparatus, the leg portions do not become obstacles, the degree of freedom in arrangement of the cushioning materials is improved, and the cushioning materials can be easily arranged. That is, the cushioning materials can be arranged at desired positions without being affected by the layout of the leg portions.

[0046] In a tenth configuration according to the ninth configuration, the supporting material, the cushioning material, and the packaging box are each formed using cardboard.

[0047] According to the configuration, since the supporting material, the cushioning material, and the packaging box are each formed using cardboard, plastic-free can be implemented with respect to the packaging material.

[0048] Further, since both the supporting material and the cushioning materials are each formed using cardboard, the supporting material and the cushioning materials can be regarded as a cushioning material as a whole. Therefore, design of impact cushioning is easier. In addition, the supporting material is regarded as a part of the cushioning material, and thus the entire thickness dimension when the cushioning material is provided in addition to the supporting material can be suppressed, which contributes to suppression of the height dimension of the entire packaged article.

[0049] The present disclosure will specifically be described below.

[0050] In FIGS. 1 and 2, a packaged article 1 is formed by housing an electronic apparatus 50 and various packaging materials in a packaging box 2. The electronic apparatus 50 is supported by a supporting material 6 inside the packaging box 2. Cushioning materials 10 (see FIG. 6) are provided under a plate-shaped portion 7. Further, the corner portions of the upper surface of the electronic apparatus 50 are protected by corner portion protection members 3 and 4 inside the packaging box 2. In the embodiment, all of the packaging box 2, the corner portion protection members 3 and 4, the plate-shaped portion 7, and the cushioning materials 10 and 11 in the configuration of the packaged article 1 are each formed using cardboard.

[0051] Here, the electronic apparatus 50 refers to, for example, a printing apparatus such as an inkjet printer. However, the electronic apparatus 50 is not limited to the printing apparatus, but may be another electronic apparatus such as an image reading apparatus that reads an image of a document, a projector that projects an image, a monitor that displays an image, or a computer that processes information.

[0052] The packaged article 1 will be specifically described below.

[0053] The X-Y-Z coordinate system shown in each drawing is an orthogonal coordinate system for description of the respective configurations of the packaged article 1 with reference to the configuration of the electronic apparatus 50. The electronic apparatus 50 has a hexahedral shape and includes a front surface 51, a right side surface 52, a left side surface 53, a top surface 54, a back surface 55, and a bottom surface 56 (see FIG. 5).

[0055] An operation panel (not illustrated) is provided on the front surface 51 of the electronic apparatus 50.

[0056] Hereinafter, each configuration of the packaged article 1 will be described using the X-Y-Z coordinate system.

[0057] The supporting material 6 and the cushioning material 10 provided under the supporting material 6 will be described later, and first, the corner portion protection members 3 and 4 and a partition member 5 will be described below.

[0058] As illustrated in FIG. 3, the corner portion protection member 3 includes a plate-shaped portion 3a-1, a plate-shaped portion 3a-2, a plate-shaped portion 3a-3, and a plate-shaped portion 3a-4. The plate-shaped portion 3a-1 faces the left side surface 53 of the electronic apparatus 50. The plate-shaped portion 3a-2 faces the +X direction region of the top surface 54 of the electronic apparatus 50. The plate-shaped portion 3a-3 faces the +X direction region of the front surface 51 of the electronic apparatus 50. The plate-shaped portion 3a-4 faces the +X direction region of the back surface 55 of the electronic apparatus 50.

[0059] The cushioning material 11 for cushioning impact is provided at a position facing each surface of the electronic apparatus 50 in each plate-shaped portion. The cushioning material 11 can reduce impact. In the embodiment, a laminated block in which cardboard are laminated is used as the cushioning material 11. In the embodiment, the cardboard forming the cushioning material 11 has a square shape in a plan view, but may have a rectangular shape or other shapes. The cushioning material 11 can be bonded to each plate-shaped portion by an adhesive. As the adhesive, various adhesives including a hot-melt type adhesive can be used, but a type of adhesive not containing an organic solvent is preferable.

[0060] The corner portion protection member 3 covers the upper portion of the electronic apparatus 50 in the +X direction, thereby protecting two corners in the upper portion in the +X direction. The two corner portions in the upper portion in the +X direction are a corner portion formed by the top surface 54, the front surface 51, and the left side surface 53, and a corner portion formed by the top surface 54, the back surface 55, and the left side surface 53.

[0061] Next, as illustrated in FIG. 4, the corner portion protection member 4 includes a plate-shaped portion 4a-1, a plate-shaped portion 4a-2, a plate-shaped portion 4a-3, and a plate-shaped portion 4a-4. The plate-shaped portion 4a-1 faces the right side surface 52 of the electronic apparatus 50. The plate-shaped portion 4a-2 faces the X direction region of the top surface 54 of the electronic apparatus 50. The plate-shaped portion 4a-3 faces the X direction region of the front surface 51 of the electronic apparatus 50. The plate-shaped portion 4a-4 faces the X direction region of the back surface 55 of the electronic apparatus 50.

[0062] The cushioning material 11 described above is provided at a position facing each surface of the electronic apparatus 50 in each plate-shaped portion.

[0063] The corner portion protection member 4 covers the upper portion of the electronic apparatus 50 in the X direction, thereby protecting two corners in the upper portion in the X direction. The two corner portions in the upper portion in the X direction are a corner formed by the top surface 54, the front surface 51, and the right side surface 52, and a corner formed by the top surface 54, the back surface 55, and the right side surface 52.

[0064] Among the cushioning materials 11 provided in the corner portion protection member 3 and the corner portion protection member 4, the cushioning materials 11 facing the side surfaces forming the periphery of the electronic apparatus 50 hold the electronic apparatus 50 so as not to move in the X-Y plane inside the packaging box 2. The side surfaces of the electronic apparatus 50 facing the cushioning materials 11 are the front surface 51, the right side surface 52, the left side surface 53, and the back surface 55. Further, among the cushioning materials 11 provided in the corner portion protection member 3 and the corner portion protection member 4, the cushioning materials 11 facing the top surface 54 of the electronic apparatus 50 and the cushioning materials 10, which will be described later, hold the electronic apparatus 50 so as not to move in the Z-axis direction inside the packaging box 2. Furthermore, the cushioning materials 11 provided in the corner portion protection member 3 and the corner portion protection member 4 and the cushioning materials 10 to be described later protect the electronic apparatus 50 from impacts applied to the packaged article 1 from various directions.

[0065] As illustrated in FIG. 1, the partition member 5 is provided in the X direction with respect to the corner portion protection member 4. The partition member 5 includes partition plates 5b forming surfaces along the Y-Z plane on plate-shaped portions 5a forming surfaces along the plate-shaped portion 4a-1 of the corner portion protection member 4. A plurality of the partition plates 5b are provided at intervals along the Y-axis direction. Accordingly, as illustrated in FIG. 2, storage spaces 2a and 2b are formed in end portions in the X direction inside the packaging box 2 with the electronic apparatus 50, the corner portion protection member 3, and the corner portion protection member 4 housed in the packaging box 2. The storage spaces 2a and 2b are formed between the partition member 5 and the packaging box 2. The storage spaces 2a and 2b extend along the Y-axis direction. The storage spaces 2a and 2b can store accessories of the electronic apparatus 50, for example, a power cable (not illustrated), an ink bottle (not illustrated), and the like in the embodiment. When it is not necessary to house the accessories, the partition member 5 may be omitted.

[0066] Next, the supporting material 6 that supports the electronic apparatus 50 will be described.

[0067] As illustrated in FIG. 1, the supporting material 6 includes a plate-shaped portion 7 that supports the electronic apparatus 50. As illustrated in FIG. 5, the plate-shaped portion 7 includes a first surface 7a that supports the electronic apparatus 50 and a second surface 7b opposite thereto. In the embodiment, the plate-shaped portion 7 is formed using a cardboard.

[0068] As illustrated in FIGS. 1, 6, 7, and 8, a plurality of holes 8 are provided in the plate-shaped portion 7. The hole 8 according to the embodiment is a through hole penetrating the plate-shaped portion 7 in the thickness direction. However, the hole 8 may be a non-through hole having a bottom.

[0069] The thickness direction of the plate-shaped portion 7 is a normal direction to the first surface 7a and the second surface 7b, and in the embodiment, the thickness direction of the plate-shaped portion 7 is along the Z-axis direction. The thickness of the plate-shaped portion 7 can also be referred to as a distance between the first surface 7a and the second surface 7b.

[0070] Here, as illustrated in FIG. 7, a plurality of leg portions 57 are provided on the bottom surface 56 of the electronic apparatus 50. In FIGS. 7 and 8, the leg portions 57 are indicated by hatched squares for convenience. As illustrated in FIG. 10, the leg portion 57 is provided so as to protrude vertically downward from the bottom surface 56 of the electronic apparatus 50. The leg portion 57 is, for example, a rubber leg, and a plurality of the leg portions are provided on the bottom surface 56 as illustrated in FIG. 7. In the embodiment, the leg portions 57 are provided so as to be unevenly distributed at the four corners of the bottom surface 56 as a whole.

[0071] In FIG. 7, the plate-shaped portion 7 and the cushioning materials 10 to be described later are drawn by virtual lines (two-dot chain lines).

[0072] As illustrated in FIG. 8, the holes 8 provided in the plate-shaped portion 7 are provided at positions corresponding to all the leg portions 57 for receiving all the leg portions 57.

[0073] When the electronic apparatus 50 is placed on the plate-shaped portion 7, all the leg portions 57 can enter the corresponding holes 8.

[0074] In FIG. 8, the cushioning materials 10 to be described later are drawn by virtual lines (two-dot chain lines).

[0075] FIG. 10 schematically shows the plate-shaped portion 7, the cushioning material 10, and the leg portion 57 for illustrating a dimensional relationship of the respective configurations in the Z-axis direction.

[0076] A sign d1 denotes a thickness dimension of the plate-shaped portion 7. A sign d2 denotes a protrusion dimension of the leg portion 57 from the bottom surface 56. A sign d3 denotes a depth dimension of the hole 8. When the hole 8 is a through hole, the thickness dimension d1 of the plate-shaped portion 7 is equal to the depth dimension d3 of the hole 8.

[0077] In the embodiment, the thickness dimension d1 of the plate-shaped portion 7 and the depth dimension d3 of the hole 8 are equal to or larger than the protrusion dimension d2 of the leg portion 57 from the bottom surface 56.

[0078] Since the depth dimension d3 of the hole 8 is equal to or larger than the protrusion dimension d2 of the leg portion 57 from the bottom surface 56, when the electronic apparatus 50 is supported by the plate-shaped portion 7, the bottom surface 56 of the electronic apparatus 50 is supported in contact with the first surface 7a of the plate-shaped portion 7. As a result, a load is less likely to be applied to the leg portion 57, and deformation of the leg portion 57 can be suppressed.

[0079] In addition, since the thickness dimension d1 is equal to or larger than the protrusion dimension d2, the leg portion 57 is unlikely to protrude from the plate-shaped portion 7. Therefore, when the cushioning materials 10 to be described later are provided on the second surface 7b of the plate-shaped portion 7, the leg portions 57 do not become obstacles, the degree of freedom in arrangement of the cushioning materials 10 is improved, and the cushioning materials 10 can be easily arranged. In particular, the cushioning materials 10 can be disposed at desired positions without being affected by the layout of the leg portion 57.

[0080] Further, since the bottom surface 56 of the electronic apparatus 50 is supported in contact with the first surface 7a of the plate-shaped portion 7, when the plate-shaped portion 7 is regarded as a part of the electronic apparatus 50, the rigidity of the entire electronic apparatus 50 during transportation can be increased. As a result, it can be avoided to separately provide a support member for supporting the electronic apparatus 50 under the electronic apparatus 50.

[0081] The thickness dimension d1 of the plate-shaped portion 7 and the depth dimension d3 of the hole 8 may be the same as the protrusion dimension d2 of the leg portion 57 from the bottom surface 56 or may be larger than the protrusion dimension d2.

[0082] In the embodiment, one hole 8 is provided for one leg portion 57, however, the present disclosure is not limited thereto. One hole 8 may be provided for a plurality of leg portions 57.

[0083] Further, in the embodiment, the hole 8 is the through hole penetrating in the thickness direction of the plate-shaped portion 7. Accordingly, the hole 8 can be easily formed at low cost. The through hole can be formed by, for example, punching.

[0084] Furthermore, in the embodiment, since the plate-shaped portion 7 is formed using the cardboard, a predetermined impact cushioning effect can be obtained by the plate-shaped portion 7.

[0085] However, the plate-shaped portion 7 is not limited to the cardboard, and may be formed using other materials as appropriate.

[0086] As illustrated in FIG. 8 as the plan view, the plate-shaped portion 7 has a size that covers the electronic apparatus 50 in the plan view. Since the plate-shaped portion 7 has the size that covers the electronic apparatus 50 in the plan view, the electronic apparatus 50 can be appropriately supported.

[0087] When the plate-shaped portion 7 is not large enough to cover the electronic apparatus 50 in the plan view, the electronic apparatus 50 may be supported using a plurality of the plate-shaped portions 7. In this case, the impact applied to the electronic apparatus 50 may not be appropriately cushioned, but when the plate-shaped portion 7 is large enough to cover the electronic apparatus 50 in the plan view, the impact applied to the electronic apparatus 50 can be appropriately cushioned.

[0088] Next, the cushioning materials 10 provided on the second surface 7b of the plate-shaped portion 7 will be described.

[0089] As shown in FIG. 6, a plurality of cushioning materials 10 for cushioning the impact are provided on the second surface 7b of the plate-shaped portion 7. The cushioning material 10 can reduce impact. In the embodiment, the cushioning material 10 is a laminated block in which cardboard are laminated similarly to the cushioning material 11 described above. In the embodiment, the cardboard forming the cushioning material 10 has a square shape in a plan view, but may have a rectangular shape or other shapes. The cushioning material 10 can be bonded to the plate-shaped portion 7 by an adhesive. This adhesive is also the same as the adhesive for bonding the cushioning material 11 described above.

[0090] Since the plurality of cushioning materials 10 are provided on the second surface 7b of the plate-shaped portion 7 as described above, an appropriate impact cushioning effect can be obtained. As described above, the degree of freedom in arrangement of the cushioning materials 10 is improved, and the cushioning materials 10 can be easily arranged. In particular, the cushioning materials 10 can be disposed at desired positions without being affected by the layout of the leg portion 57.

[0091] The cushioning material 10 according to the embodiment is obtained by bonding a plurality of cardboard sheets with an adhesive, and includes a first cushion portion 10a and a second cushion portion 10b as illustrated in FIG. 9.

[0092] The first cushion portion 10a is formed by stacking first cushion sheets 10c. The second cushion portion 10b is formed by stacking second cushion sheets 10d. The density of the core provided in the first cushion sheet 10c is higher than the density of the core provided in the second cushion sheet 10d, and thus the first cushion sheet 10c has higher strength in the Z-axis direction than the second cushion sheet 10d.

[0093] According to the configuration, as described in JP-A-2023-120487, when the packaged article 1 is dropped from a predetermined height with the cushioning material 10 interposed between the electronic apparatus 50 and the floor surface, the second cushion sheet 10d is compressed and crushed earlier than the first cushion sheet 10c. This is because the strength in the Z-axis direction of the second cushion sheet 10d is lower than that of the first cushion sheet 10c. However, the impact can be cushioned by the first cushion sheet 10c disposed at the electronic apparatus 50 side.

[0094] In this case, in a graph (not shown) in which the vertical axis indicates an external force applied to the electronic apparatus 50 via the cushioning material 10 and the horizontal axis indicates a time from the start of application of the external force via the cushioning material 10 to the electronic apparatus 50, the waveform of the external force applied to the electronic apparatus 50 via the cushioning material 10 is a sine half-wave.

[0095] As a result, the possibility that resonance occurs in the system including the electronic apparatus 50 and the cushioning material 10 can be reduced as compared with a configuration in which the cushioning material 10 is formed using only the second cushion sheet 10d. Thus, the occurrence of a failure in the electronic apparatus 50 can be reduced.

[0096] In the cushioning material 11 described with reference to FIGS. 3 and 4, similarly to the cushioning material 10, the plurality of first cushion sheets 10c are disposed at the electronic apparatus 50 side, and the plurality of second cushion sheets 10d are disposed at the side farther from the electronic apparatus 50 than the first cushion sheets 10c. According to the configuration, the same effects as those of the cushioning material 10 are obtained.

[0097] Next, in the embodiment, as shown in FIGS. 7 and 8, a part of the cushioning material 10 is located at a position overlapping at least a part of the plurality of holes 8. Accordingly, when the electronic apparatus 50 receives drop impact, at least a part of the plurality of leg portions 57 can be supported by the cushioning material 10, that is, the impact can be received by both the cushioning material 10 and the leg portions 57.

[0098] In the embodiment, part of the plurality of holes 8 are located at positions overlapping the cushioning material 10, but all of the plurality of holes 8 may be located at positions overlapping the cushioning material 10.

[0099] Further, since both the plate-shaped portion 7 and the cushioning material 10 are each formed using cardboard, the plate-shaped portion 7 and the cushioning material 10 can be regarded as the cushioning material 10 as a whole. Therefore, design of impact cushioning is easier. In addition, the plate-shaped portion 7 is regarded as a part of the cushioning material 10, and thus the entire thickness dimension da (see FIG. 9) when the cushioning material 10 is provided in addition to the plate-shaped portion 7 can be suppressed, which contributes to suppression of the entire height dimension of the packaged article 1.

[0100] The packaged article 1 includes the electronic apparatus 50 having the plurality of leg portions 57 on the bottom surface 56, the supporting material 6 that supports the electronic apparatus 50 in the packaged state, the cushioning material 10 that cushions the impact applied to the electronic apparatus 50, and the packaging box 2 in which the electronic apparatus 50, the supporting material 6, and the cushioning material 10 are housed. Therefore, according to the packaged article 1, the above described functions and effects by the supporting material 6 can be obtained.

[0101] In the embodiment, since all of the packaging box 2, the corner portion protection members 3 and 4, the supporting material 6, and the cushioning materials 10 and 11 of the configurations of the packaged article 1 are each formed using cardboard, plastic-free can be implemented with respect to the packaging material.

[0102] A packaging procedure can be as follows.

[0103] First, the supporting material 6 provided with the cushioning materials 10 is placed on a workbench or a floor, and the electronic apparatus 50 is placed on the supporting material 6.

[0104] Then, the electronic apparatus 50 and the supporting material 6 are housed in the packaging box 2, and the corner portion protection members 3 and 4 and the partition member 5 are arranged. Then, accessories of the electronic apparatus 50 are stored in the storage spaces 2a and 2b, and when there is an instruction manual or the like, the instruction manual is placed on the top surface 54 of the electronic apparatus 50, and the packaging box 2 is closed.

[0105] The procedure can be appropriately changed. For example, the electronic apparatus 50 may be placed on the supporting material 6 with the supporting material 6 housed in the packaging box 2 in advance. Further, the components inside the packaging box 2 may be assembled and then collectively housed in the packaging box 2.

[0106] The plate-shaped portion 7 of the supporting material 6 has a dimension in the Y-axis direction slightly smaller than the dimension of the internal space of the packaging box 2 in the Y-axis direction. As a result, the electronic apparatus 50 and the supporting material 6 can be suppressed from rattling in the Y-axis direction with the electronic apparatus 50 and the supporting material 6 housed in the packaging box 2. In the embodiment, the plate-shaped portion 7 of the supporting material 6 has a dimension in the X-axis direction smaller than the dimension of the internal space of the packaging box 2 in the X-axis direction. The movement of the electronic apparatus 50 and the supporting material 6 in the X-axis direction inside the packaging box 2 is restricted by the partition plates 5b of the partition member 5. However, the dimension of the plate-shaped portion 7 of the supporting material 6 in the X-axis direction may be slightly smaller than the dimension of the internal space of the packaging box 2 in the X-axis direction.

[0107] Next, another embodiment of the hole provided in the plate-shaped portion will be described with reference to FIG. 11. Like FIG. 10, FIG. 11 is a schematic diagram.

[0108] The embodiment shown in FIG. 11 is different from the above described embodiment in that a hole 9 as a non-through hole is adopted instead of the hole 8 as the through hole. The hole 9 is formed in a plate-shaped portion 7A.

[0109] In FIG. 11, the thickness dimension d1 of the plate-shaped portion 7A and the depth dimension d3 of the hole 9 are equal to or larger than the protrusion dimension d2 of the leg portion 57 from the bottom surface 56. Accordingly, similarly to the plate-shaped portion 7 described above, the bottom surface 56 of the electronic apparatus 50 is supported in contact with the first surface 7a with the electronic apparatus 50 supported by the plate-shaped portion 7A. Therefore, a load is hardly applied to the leg portion 57, and deformation of the leg portion 57 can be suppressed.

[0110] The plate-shaped portion 7A can be formed, for example, by bonding a cardboard sheet with a through hole formed therein and a cardboard sheet with no through hole formed therein using an adhesive. According to the configuration, similarly to the plate-shaped portion 7 described above, the plate-shaped portion 7A and the cushioning material 10 can be regarded as the cushioning material 10 as a whole. Therefore, design of impact cushioning is easier. In addition, the plate-shaped portion 7A is regarded as a part of the cushioning material 10, and thus the entire thickness dimension when the cushioning material 10 is provided in addition to the plate-shaped portion 7A can be suppressed, which contributes to suppression of the entire height dimension of the packaged article 1. Further, the plate-shaped portion 7A is formed using a plurality of cardboard sheets, and thus the rigidity of the plate-shaped portion 7A can be improved.

[0111] The present disclosure is not limited to the above described embodiments and modifications. Various modifications can be made within the scope of the disclosure set forth in claims. It is obvious that the modifications also fall within the scope of the present disclosure.
