[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming unnecessarily redundant and to facilitate understanding by those skilled in the art.

[0011] The inventor(s) provide the accompanying drawings and the following description so that those skilled in the art can fully understand the present disclosure, and do not intend for them to limit the subject matter described in the claims.

[0012] Hereinafter, an imaging device according to an embodiment of the present disclosure will be described with reference to the drawings.

[0013] 1 is a schematic perspective view of an imaging device according to an embodiment of the present disclosure. Note that the XYZ Cartesian coordinate system shown in the figure is for facilitating understanding of the embodiment of the present disclosure and does not limit the embodiment of the present disclosure. The X-axis direction is the front-rear direction of the imaging device, the Y-axis direction is the left-right direction, and the Z-axis direction is the height direction. The optical axis of the imaging device extends in the front-rear direction.

[0014] As shown in FIG. 1, an imaging device 10 according to this embodiment has a housing 12, a lens mount 14 provided on a front surface 12a of the housing 12, and a shutter button 16 provided on a top surface 12b of the housing 12.

[0015] The housing 12 of the imaging device 10 has a left side surface 12c and a right side surface 12d that are curved surfaces. In the present embodiment, the left side surface 12c and the right side surface 12d are convex single curved surfaces. For example, the left side surface 12c and the right side surface 12d are arc-shaped in the height direction (Z-axis direction).

[0016] The housing 12 of the imaging device 10 also includes a grip that is held by the user. Specifically, leather sheets 18, 20 are attached to a portion of the housing 12, and the portion of the housing 12 to which the leather sheets 18, 20 are attached functions as the grip of the imaging device 10.

[0017] The leather sheets 18, 20 are attached to the housing 12 to enhance the design and / or to prevent the user's hand from slipping when holding the imaging device 10. The leather sheets 18, 20 are sheet members made of, for example, genuine leather, synthetic leather, or artificial leather. In the case of the present embodiment, the leather sheets 18, 20 are attached to the front surface 12a of the housing 12 with the lens mount 14 sandwiched therebetween. A portion of the leather sheet 18 is attached to the left side surface 12c. A portion of the leather sheet 20 is attached to the right side surface 12d. That is, the leather sheets 18, 20 are attached to the housing 12 with a portion bent.

[0018] From here, further features of the leather seats 18 and 20 will be described. Although the leather seats 18 and 20 have different shapes, they have substantially the same configuration. Therefore, the leather seat 18 will be described below, and the description of the leather seat 20 will be omitted.

[0019] Fig. 2 is a perspective view of the leather sheet showing the outer surface of the leather sheet, Fig. 3 is a perspective view of the leather sheet showing the inner surface of the leather sheet, Fig. 4 is a cross-sectional view taken along line AA in Fig. 3, and Fig. 5 is a cross-sectional view showing a part of the leather sheet attached to the housing 12.

[0020] As shown in Figs. 1 to 5, in this embodiment, the leather sheet 18 has an outer surface 18a that is exposed to the outside when attached to the housing 12 of the imaging device 10, and an inner surface 18b that is attached to the housing 12. In this embodiment, the leather sheet 18 is attached to the housing 12 via an attachment member 22. The attachment member 22 is interposed between the inner surface 18b of the leather sheet 18 and the curved left side surface 12c of the housing 12 to attach the leather sheet 18 to the housing 12. In this embodiment, the attachment member 22 is a double-sided tape 22. The double-sided tape 22 is an attachment member in which adhesive layers are formed on both sides of a sheet-like base material such as a highly flexible nonwoven fabric or paper.

[0021] As shown in Figures 4 and 5, the leather sheet 18 has a plurality of cuts 18c on its inner surface 18b, for reasons that will be described later. The plurality of cuts 18c are formed in a portion 18d (curved portion) of the leather sheet 18 that is attached to the case 12 and curved. Specifically, as shown in Figure 5, when the inner surface 18b of the leather sheet 18 is attached to the left side surface 12c, which is the curved surface of the case 12, the plurality of cuts 18c are formed in the leather sheet 18 so as to line up along the left side surface 12c, i.e., so as to line up in the curved direction CR (white arrow) of the left side surface 12c.

[0022] In this embodiment, the cuts 18c extend linearly and parallel to each other at intervals when the leather sheet 18 is in a flat state before being attached to the curved left side surface 12c, as shown in Fig. 3. Furthermore, each of the cuts 18c extends in a direction perpendicular to the curvature direction CR.

[0023] The multiple cuts 18c are formed in the leather sheet 18 by a so-called half-cut process. Specifically, in the present embodiment, the multiple cuts 18c are laser-processed grooves formed by laser processing. That is, the multiple cuts 18c are spaces formed by removing a part of the leather sheet 18 by laser irradiation.

[0024] The laser processing of the leather sheet 18 is performed in a state where the double-sided tape 22 is attached to the inner surface 18b of the leather sheet 18. Specifically, as shown in Fig. 4, the laser is irradiated toward the inner surface 18b of the leather sheet 18 in a state where the release paper RP is present on the surface opposite to the surface to be attached to the inner surface 18b of the leather sheet 18. As a result, a through-cut 22a is formed in the part of the double-sided tape 22 facing the cut 18c of the leather sheet 18.

[0025] 3, in this embodiment, one end of each of the multiple cuts 18c extends to one end of the leather sheet 18. However, the other end of each of the multiple cuts 18c does not extend to the other end of the leather sheet 18. In contrast, if laser processing is performed so that each of the multiple cuts 18c extends to the other end of the leather sheet 18, the release paper RP of the double-sided tape 22 will be divided into multiple pieces, and the multiple divided release papers RP will have to be peeled off one by one, which will be a hassle.

[0026] Due to the plurality of cuts 18c as described above, the leather sheet 18 attached to the curved left side surface 12c of the housing 12 is less likely to peel off.

[0027] Specifically, the thicker the leather sheet 18 is, the less likely it is to bend. In other words, the greater the restoring force that returns the leather sheet 18 from a curved state to a flat state. When this restoring force exceeds the adhesive force at the interface between the housing 12 and the double-sided tape 22, peeling occurs at this interface. For example, when the curvature of the curved surface to which the leather sheet is attached is R12.5, a leather sheet with a thickness of 0.35 mm will not peel off, but a leather sheet with a thickness of 0.8 mm will peel off. Also, the greater the curvature of the curved left side surface 12c to which the leather sheet 18 is attached, the more likely the leather sheet 18 will peel off. Even if peeling does not occur, the adhesive force at the interface between the housing 12 and the double-sided tape 22 weakens, making the leather sheet 18 more likely to peel off. For example, when the leather sheet 18 is in a state where it is more likely to peel off, if the grip of the user's hand that holds the housing 12 through the leather sheet 18 becomes stronger, the leather sheet 18 may slip over the housing 12 and peel off.

[0028] When the curvature of the curved surface to which the leather sheet 18 is attached and the thickness of the leather sheet 18 are values ​​that may cause peeling of the leather sheet 18, multiple cuts 18c are formed in the leather sheet 18 as shown in FIG. 3. The cross-sectional area of ​​the portion of the leather sheet 18 where the multiple cuts 18c are formed is reduced compared to other portions. Due to the reduction in cross-sectional area, the portion of the leather sheet 18 where the cuts 18c are formed and the neighboring portion have a lower flexural rigidity compared to other portions, that is, a smaller restoring force to return from a curved state to a flat state. As a result, the portion of the leather sheet 18 attached to the curved surface has multiple portions with intermittent reduced restoring force in the curve direction CR. As a result, the restoring force of the entire leather sheet 18 is reduced compared to when the multiple cuts 18c are not present.

[0029] In the present embodiment, the plurality of cuts 18c are groove-shaped with an opening width W when the leather sheet 18 is in a flat state, as shown in FIG. 4. When the leather sheet 18 is attached to the left side surface 12c of the housing 12, as shown in FIG. 5, each of the plurality of cuts 18c is deformed and the opening width is reduced from W to W-Δw (Δw is the amount of deformation). Such deformation of the plurality of cuts 18c suppresses the occurrence of wrinkles on the inner surface 18b of the leather sheet 18 facing the left side surface 12c of the housing 12. Unlike the present embodiment, if the plurality of cuts 18c do not exist, compressive stress is generated on the entire inner surface 18b of the concavely curved leather sheet 18, and wrinkles may occur locally on the inner surface 18b. When wrinkles occur, the corresponding portion of the double-sided tape 22 becomes wavy. As a result, the adhesive force between the housing 12 and the wavy double-sided tape 22 is weakened, and the leather sheet 18 is more likely to peel off.

[0030] If the number of the multiple cuts 18c is too large, the adhesion area between the double-sided tape 22 and the curved left side surface 12c of the housing 12 decreases, making the leather sheet 18 more likely to peel off. If the opening width W of each of the multiple cuts 18c is too large, a dent will occur in the portion of the outer surface 18a of the leather sheet 18 that corresponds to the cut 18c. Therefore, the number of the multiple cuts 18c and the opening width W are appropriately adjusted depending on the thickness of the leather sheet 18, the curvature of the curved surface to which the leather sheet 18 is attached, and the like.

[0031] According to the present embodiment as described above, in a grip for an imaging device that has a curved surface to which a leather sheet can be attached, peeling of the leather sheet can be suppressed.

[0032] Although the embodiments of the present disclosure have been described above, the embodiments of the present disclosure are not limited to these.

[0033] For example, in the case of the above-described embodiment, as shown in Fig. 5, the leather sheet 18 is attached to the curved left side surface 12c of the housing 12 of the imaging device 10 via a double-sided tape 22. However, the attachment member for attaching the leather sheet to the curved surface is not limited to the double-sided tape 22. The attachment member may be, for example, an adhesive.

[0034] In the above-described embodiment, as shown in Fig. 4 and Fig. 5, the multiple cuts 18c formed in the leather sheet 18 are grooves formed by laser processing. However, the embodiment of the present disclosure is not limited to this. The cuts formed in the leather sheet may be slits formed by a blade such as a cutter. Even in this case, the cross-sectional area is locally reduced, so that the restoring force of the leather sheet can be reduced, similar to the groove-shaped cuts.

[0035] 3, each of the cuts 18c extends in a direction perpendicular to the curvature direction CR of the curved left side surface 12c of the housing 12. However, the embodiment of the present disclosure is not limited to this. Each of the cuts may extend in a direction inclined at 45 degrees to the curvature direction of the curved surface.

[0036] Regarding the cuts in the leather sheet, in the above-described embodiment, multiple cuts 18c are formed in the inner surface 12b of the leather sheet 18. However, the embodiment of the present disclosure is not limited to this. For example, when the area of ​​the curved surface of the housing to which the leather sheet is attached is small, when the curvature of the curved surface is small, and / or when the thickness of the leather sheet is small, the leather sheet may have only one cut.

[0037] Furthermore, in the case of the above-described embodiment, the left side surface 12c of the housing 12 to which the leather sheet 18 is attached is a single convex curved surface as shown in Fig. 1 and Fig. 5. However, the embodiment of the present disclosure is not limited thereto. For example, the curved surface to which the leather sheet is attached may be a single concave curved surface.

[0038] In addition, in the case of the above-described embodiment, as shown in Fig. 1, a portion of the housing 12 to which the leather sheets 18, 20 are attached functions as a grip for the imaging device 10. In other words, the grip is non-detachably provided on the housing 12 of the imaging device 10. However, the embodiment of the present disclosure is not limited to this. The grip for the imaging device according to the embodiment of the present disclosure may be a grip that is detachable from the housing of the imaging device as an option.

[0039] That is, the grip according to the embodiment of the present disclosure, in a broad sense, comprises a housing having a curved surface, a leather sheet having an inner surface and an outer surface, and an attachment member interposed between the inner surface of the leather sheet and the curved surface of the housing for attaching the leather sheet to the housing, and the inner surface of the leather sheet has at least one non-penetrating notch that is aligned in the curvature direction of the curved surface when the leather sheet is attached to the curved surface of the housing.

[0040] As described above, the above-mentioned embodiment has been described as an example of the technology in the present disclosure. For this purpose, drawings and detailed description are provided. Therefore, among the components described in the drawings and detailed description, not only components essential for solving the problem but also components that are not essential for solving the problem in order to illustrate the above-mentioned technology may be included. Therefore, the fact that these non-essential components are described in the drawings or detailed description should not be used to immediately determine that these non-essential components are essential.

[0041] Furthermore, since the above-described embodiments are intended to illustrate the technology in the present disclosure, various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents. [Industrial Applicability]
