[0086] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings attached to this specification, for the convenience of illustration and understanding, the scale, the aspect ratio in the vertical and horizontal directions, etc. are appropriately exaggerated compared to the actual object.

[0087] The terms "plate", "sheet", and "film" are not distinguished from each other merely by name. For example, the concept of "plate" also includes components that can be called sheets or films. Therefore, a "light diffusing plate" and components called "light diffusing sheets" or "light diffusing films" cannot be distinguished from each other merely by name.

[0088] Regarding terms such as "parallel", "orthogonal", "identical", etc. for shape, geometric conditions, and the degree of determining them, as well as values of length, angle, etc., they are not limited to strict meanings and are interpreted to include ranges to the extent that the same functions can be expected.

[0089] In the present invention, terms such as "sheet", "film", "plate", etc. are not distinguished from each other merely based on name differences. For example, a "decorative sheet" and components called decorative films or decorative sheets cannot be distinguished merely based on name differences.

[0090] To clarify the directional relationship between the drawings, in multiple drawings, arrows marked with a common symbol are used to indicate the common direction. The front end side of the arrow becomes the first side of each direction. An arrow coming forward from the paper surface along a direction perpendicular to the paper surface of the drawing is represented, for example, as Figure 2 shown by a symbol with a dot set in a circle. For example, as Figure 4 shown, an arrow going to the back side of the paper surface along a direction perpendicular to the paper surface of the drawing is represented by a symbol with an X set in a circle.

[0091] In the present invention, when multiple upper limit candidates and multiple lower limit candidates are listed for a certain parameter, the numerical range of this parameter can also be constituted by combining any one upper limit candidate and any one lower limit candidate. As an example, consider the description "Parameter B can be A1 or more, can be A2 or more, and can also be A3 or more. Parameter B can be A4 or less, can be A5 or less, and can also be A6 or less." In this example, the numerical range of parameter B can be A1 or more and A4 or less, can be A1 or more and A5 or less, can be A1 or more and A6 or less, can be A2 or more and A4 or less, can be A2 or more and A5 or less, can be A2 or more and A6 or less, can be A3 or more and A4 or less, can be A3 or more and A5 or less, and can be A3 or more and A6 or less.

[0092] Figures 1 to 15 is a diagram illustrating one embodiment. Figure 1 is a perspective view schematically showing a specific example of a display system. As Figure 1As shown, the display system 10 includes a light source 15 and a decorative component 20 that overlaps with the light source 15. The display system 10 can be observed from the display surface 11. The display surface 11 can also display a design. The display surface 11 can also display an image. The image can also be formed by the light of the light source 15 emitted from the display surface 11.

[0093] The display system 10 can be applied to various uses. The display system 10 can also be applied to the interior or exterior decoration of a moving body that is a movable device. As a moving body, examples include an automobile, a ship, an airplane, etc. As a specific example, the display system 10 can also be applied to the interior and exterior decoration of an automobile. The display system 10 can also be applied to walls, doors, ceilings, etc. that are the interior decoration of a building. The display system can also be applied to various devices such as furniture and household appliances.

[0094] The light source 15 can emit light. The light source 15 can be in a state of emitting light (lit state) and a state of stopping light emission (extinguished state). The light source 15 can also include a cold cathode tube as a light-emitting body. The light source 15 can also include a light-emitting diode (LED) as a light-emitting body. The light source 15 can further include an optical component capable of adjusting the orientation of the light from the light-emitting body. The light source 15 can also be a surface light source device that emits light in a planar shape.

[0095] In Figure 1 and Figure 4 In the example shown, the light source 15 is covered by the decorative component 20 and the decorative outer cover 40. The decorative outer cover is a sheet from which a part has been removed from the decorative sheet. The light source 15 includes a part that faces a recess 45 described later of the decorative outer cover 40. The light source 15 is shielded from the observer observing the decorative outer cover 40 by the decorative outer cover 40.

[0096] In Figures 1 to 3 In the example shown, the decorative component 20 extends in a sheet shape in a global view. The decorative component 20 extends in a first direction D1 and a second direction D2 orthogonal to the first direction D1. The decorative component 20 includes a decorative outer cover 40 and a thermoplastic resin part 32 that overlaps with the decorative outer cover 40 from a third direction D3. The thermoplastic resin part 32 is joined to the decorative outer cover 40. The thermoplastic resin part 32 is located between the light source 15 and the decorative outer cover 40 in the third direction D3.

[0097] In Figures 1 to 4 In the example shown, the decorative component 20 has a first surface 20a and a second surface 20b opposite to the first surface 20a. The first surface 20a constitutes the display surface 11 of the display system 10. The observer of the display system 10 observes the display surface 11. The decorative component 20 can be observed from the first surface 20a. The decorative component 20 faces the light source 15 on the second surface 20b.

[0098] The decorative member 20 displays the design represented by the decorative cover member 40. The design displayed by the decorative member 20 is also displayed as a design appearance in the display system 10. In Figure 2 and Figure 3 In the decorative member 20 shown, as the design represented by the decorative cover member 40, a design with a wood grain pattern can be observed.

[0099] In Figures 1 to 3 In the example shown, the decorative member 20 has a transmissive portion 21 and a light-shielding portion 22. The transmissive portion 21 has visible light transmissibility. The light-shielding portion 22 has visible light light-shielding property. In the display system 10, the light emitted from the light source 15 to the decorative member 20 can pass through the transmissive portion 21. The light emitted from the light source 15 to the decorative member 20 can be absorbed by the light-shielding portion 22. The decorative member 20 can recognize the transmissive portion 21 with respect to the light-shielding portion 22 by using the difference in transmittance between the transmissive portion 21 and the light-shielding portion 22. An observer can observe the transmissive portion 21 as a display pattern. The transmissive portion 21 only needs to have visible light transmissibility that can transmit visible light to a degree distinguishable from the light-shielding portion 22. The transmissive portion 21 may not have visible light transmissibility that can transmit visible light to a degree that can be called transparent. The transmissive portion 21 may be smoke tinted. The light-shielding portion 22 only needs to have visible light light-shielding property that can block visible light to a degree distinguishable from the transmissive portion 21.

[0100] "Visible light transmissibility" means that the visible light transmittance is 3% or more. "Transparent" means that the visible light transmittance is 50% or more, preferably 80% or more. "Visible light light-shielding property" means that the visible light transmittance is 1% or less, preferably 0.2% or less. The visible light transmittance is determined as the average value of the transmittances of each wavelength measured at an incident angle of 0° every 1 nm in the measurement wavelength range of 380 nm to 780 nm. The transmittance of each wavelength is measured using a haze meter (manufactured by Murakami Color Technology Research Institute, product number: HM-150) based on JIS K7361.

[0101] Figure 3 The display system 10 shown can display the pattern of the transmissive portion 21 as an image by using the difference in visible light transmittance between the transmissive portion 21 and the light-shielding portion 22. In the illustrated example, a cross, a triangle, and a quadrilateral are displayed.

[0102] The decorative member 20 may have a three-dimensional shape. In Figure 1 In the example shown, both end portions of the decorative member 20 in the first direction D1 are bent in the third direction D3. The bent portions of the decorative member 20 extend in the second direction D2.

[0103] In Figure 4In the example shown, the decorative outer cover 40 has a first surface 40a and a second surface 40b opposite to the first surface 40a. The first surface 40a constitutes the first surface 20a of the decorative member 20. Therefore, the first surface 40a of the decorative outer cover 40 constitutes the display surface 11 of the display system 10. In the illustrated example, the first surface 40a is flat. The decorative outer cover 40 is joined to the thermoplastic resin portion 32 at the second surface 40b.

[0104] The decorative outer cover 40 includes a design layer 51 and a light-shielding layer 52 from the first surface 40a toward the second surface 40b. Figure 4 In the example shown, the design layer 51 and the light-shielding layer 52 are stacked in the third direction D3. That is, in the illustrated decorative outer cover 40, the third direction D3 is the stacking direction.

[0105] The decorative outer cover 40 may also include layers other than the design layer 51 and the light-shielding layer 52. Figure 4 In the example shown, the decorative outer cover 40 sequentially includes a surface layer 62, a design layer 51, a base layer 61, a light-shielding layer 52, and a bonding layer 63 from the first surface 40a toward the second surface 40b.

[0106] In Figures 2 to 4 the example shown, the decorative outer cover 40 has a transmissive portion 41 and a light-shielding portion 42. Figure 4 In the example shown, the transmissive portion 41 and the light-shielding portion 42 are adjacent to each other in the first direction D1. The transmissive portion 41 has visible light transmissivity. The light-shielding portion 42 has visible light light-shielding property. In the illustrated decorative outer cover 40, the light-shielding portion 42 is located in the portion including the light-shielding layer 52. The transmissive portion 41 is located in the portion not including the light-shielding layer 52.

[0107] In the illustrated display system 10, the transmissive portion 41 can transmit the light emitted from the light source 15. The light-shielding portion 42 can absorb the light emitted from the light source 15. In the decorative member 20 including the decorative outer cover 40, the transmissive portion 21 may also be formed by the transmissive portion 41 of the decorative outer cover 40. The light-shielding portion 22 may also be formed by the light-shielding portion 42 of the decorative outer cover 40.

[0108] In Figure 4 the example shown, the decorative outer cover 40 includes a recess 45 that opens at the second surface 40b. The recess 45 does not open at the first surface 40a. That is, the recess 45 does not penetrate the decorative outer cover 40 in the stacking direction. The decorative outer cover 40 is recessed in the third direction D3, which is the stacking direction, at the recess 45.

[0109] In Figure 4In the decorative outer cover 40 shown, three recesses 45 are arranged in the first direction D1. The thermoplastic resin part 32 joined to the decorative outer cover 40 is located within the recesses 45. The decorative outer cover 40 allows the light emitted from the light source 15 to pass through at the recesses 45.

[0110] The recesses 45 penetrate the light-shielding layer 52. By penetrating the light-shielding layer 52, the decorative outer cover 40 can have visible light transmissivity at the recesses 45. Therefore, the recesses 45 can form the transmissive parts 41 of the decorative outer cover 40. As Figure 4 shown, the recesses 45 may also penetrate layers other than the light-shielding layer 52 of the decorative outer cover 40. In the illustrated example, the recesses 45 also penetrate the bonding layer 63. The recesses 45 are formed by the part penetrating the light-shielding layer 52 and the part penetrating the bonding layer 63. The recesses 45 may also be formed by removing a part of the light-shielding layer 52 from the second surface 40b side of the decorative outer cover 40. The light-shielding layer 52 may also be removed by laser irradiation from the second surface 40b side of the decorative outer cover 40.

[0111] The recesses 45 do not penetrate the design layer 51. As Figure 4 shown, the recesses 45 may also not penetrate layers other than the design layer 51 of the decorative outer cover 40. In the illustrated example, the recesses 45 also do not penetrate the base layer 61. In the decorative outer cover 40, different from the illustrated example, the recesses 45 may be formed in a part of the base layer 61. In the decorative outer cover 40, different from the illustrated example, the recesses 45 may also penetrate the base layer 61.

[0112] As described above, the recesses 45 penetrate the light-shielding layer 52 and do not penetrate the design layer 51. That is, the recesses 45 only penetrate the light-shielding layer 52 among the light-shielding layer 52 and the design layer 51. Only the light-shielding layer 52 among the light-shielding layer 52 and the design layer 51 is penetrated by the recesses 45.

[0113] Figure 4 The recesses 45 shown include a bottom 46 and a wall part 48 connecting the bottom 46 and the second surface 40b. In the illustrated decorative outer cover 40, the bottom 46 is located on the side closer to the first surface 40a than the wall part 48. The "bottom" refers to the part of the recess where the angle with respect to the lamination direction is 45° or more and 90° or less. The illustrated bottom 46 faces the third direction D3. That is, the angle of the illustrated bottom 46 with respect to the lamination direction is 90°. The "wall part" refers to the part of the recess where the angle with respect to the lamination direction is 0° or more and less than 45°. The illustrated wall part 48 extends along the third direction D3 between the bottom 46 and the second surface 40b. That is, the angle of the illustrated wall part 48 with respect to the lamination direction is 0°.

[0114] In Figure 4In the illustrated decorative exterior member 40, the bottom portion 46 is formed of the base layer 61. In the illustrated decorative exterior member 40, the wall portion 48 is formed of the light-shielding layer 52 and the bonding layer 63. In the illustrated decorative exterior member 40, the recessed portion 45 is not formed in the design layer 51. In the illustrated recessed portion 45, neither the bottom portion 46 nor the wall portion 48 is formed of the design layer 51.

[0115] Hereinafter, mainly with reference to Figure 4 the components of the decorative exterior member 40 will be described.

[0116] In Figure 4 the illustrated example, the surface layer 62 forms the first surface 40a of the decorative exterior member 40. The surface layer 62 may also form the observer-side surface of the decorative member 20. The surface layer 62 may also be transparent. The surface layer 62 may also be colored. In a specific example of the illustrated decorative exterior member 40, the design layer 51 can be observed through the transparent surface layer 62. The surface layer 62 may also perform various functions. The surface layer may be a hard coat that exhibits scratch resistance. The surface layer may be an antifouling layer that exhibits an antifouling function. The surface layer may be an antiglare layer that exhibits an antiglare function. The surface layer may be an antireflection layer that exhibits an antireflection function.

[0117] The surface layer 62 may also contain a thermoplastic resin. The surface layer 62 may contain a cured product of a curable resin composition. The curable resin composition may contain one or more of an ionizing radiation curable resin and a thermosetting resin. The ionizing radiation curable resin may contain an ultraviolet curable resin and an electron beam radiation resin. The thickness of the surface layer 62 is not particularly limited. The thickness of the surface layer 62 (the length in the third direction D3 in Figure 4 this case) may be 1 μm or more, and may also be 5 μm or more. The thickness of the surface layer 62 may be 1000 μm or less, may be 500 μm or less, may also be 100 μm or less, or may be 30 μm or less. The surface layer 62 may also be omitted from the decorative exterior member 40.

[0118] In Figure 4 the illustrated example, the design layer 51 is located between the surface layer 62 and the base layer 61 in the third direction D3. The design layer 51 is located at a position straddling the transmissive portion 41 and the light-shielding portion 42 of the decorative exterior member 40. In other words, the design layer 51 is located at a position facing both the transmissive portion 41 and the light-shielding portion 42 of the decorative exterior member 40. The design layer 51 forms the design displayed by the decorative exterior member 40.

[0119] The design layer 51 can transmit light emitted from the light source 15. In Figure 4 the illustrated example, the design layer 51 can transmit light emitted from the light source 15 in the portion overlapping with the recessed portion 45. Thus, as Figure 3As shown, in the portion overlapping with the recess 45, the light passing through the design layer 51 and the surface layer 62 can be displayed as display light.

[0120] The design layer 51 may also have visible light transmissivity. The visible light transmittance of the design layer 51 may be 10% or more, or may be 20% or more. The visible light transmittance of the design layer 51 may be 50% or less, or may be 40% or less.

[0121] The design displayed by the design layer 51 may also include one or more of patterns such as graphics, patterns, designs, colors, pictures, photos, characters, marks, pictograms, texts, numbers, etc. The design layer 51 can also perform the design expression of the display background. For example, as a design that can be coordinated with the surrounding environment where the display system 10 is provided, patterns in a wood grain style, a marble style, and geometric patterns can also be displayed by the design layer 51. In Figure 2 and Figure 3 In the example shown, the design layer 51 forms a pattern in a wood grain style.

[0122] The design layer 51 may include an adhesive resin part and a colorant held by the adhesive resin part. The adhesive resin part may include a thermoplastic resin. The adhesive resin part may include a cured product of a curable resin composition. The curable resin composition may include one or more of an ionizing radiation curable resin and a thermosetting resin. The ionizing radiation curable resin may include an ultraviolet curable resin and an electron beam radiation resin. The colorant may be a dye, a pigment, or a combination of a dye and a pigment.

[0123] The design layer 51 may also be formed by printing. The design layer 51 may also be formed by transfer. The thickness of the design layer 51 may be 1 μm or more and 30 μm or less.

[0124] In Figure 4 In the example shown, the base layer 61 is located between the design layer 51 and the light shielding layer 52 in the third direction D3. The base layer 61 can transmit the light emitted from the light source 15. The base layer 61 may also have visible light transmissivity. The visible light transmittance of the base layer 61 may be 30% or more, or may be 40% or more. The base layer 61 may also be transparent. The illustrated base layer 61 is a transparent film. As the base layer 61, a film may also be used. The base layer 61 may also be formed by coating. The base layer 61 may also be a coating. When the base layer 61 is a coating, a film may be used for the surface layer 62. The base layer 61 may also support the design layer 51. The base layer 61 may also support the light shielding layer 52. The base layer 61 may also support layers other than the base layer 61 of the decorative cover 40.

[0125] The base layer 61 may also contain a resin. The base layer 61 may also contain a thermoplastic resin. The base layer 61 may also be a film made of a thermoplastic resin. The thermoplastic resin may include one or more of acrylic, PET (polyethylene terephthalate), polyolefin resins such as polypropylene and polyethylene, polycarbonate, and ABS (acrylonitrile-butadiene-styrene copolymer resin). The base layer 61 may also be colored. The base layer 61 may also form the design exhibited by the decorative exterior member 40.

[0126] The thickness of the base layer 61 may be 1 μm or more, and may also be 5 μm or more. By setting a lower limit for the thickness of the base layer 61, it is possible to suppress the recess 45 formed by laser etching from the second surface 40b side from penetrating the design layer 51, and the detailed content will be described later. The thickness of the base layer 61 may be 500 μm or less, and may also be 300 μm or less. By setting an upper limit for the thickness of the base layer 61, the formability of the decorative exterior member 40 can be improved.

[0127] In Figure 4 In the example shown, the light-shielding layer 52 is located between the base layer 61 and the bonding layer 63 in the third direction D3. The light-shielding layer 52 has visible light-shielding properties. Since the light-shielding layer 52 has visible light-shielding properties, the light from the light source 15 can be absorbed by the light-shielding layer 52. Therefore, the incidence of the light from the light source 15 to the portion of the design layer 51 that overlaps with the light-shielding layer 52 is suppressed. That is, in the illustrated example, the light-shielding layer 52 forms the light-shielding portion 42 of the decorative exterior member 40.

[0128] The light-shielding layer 52 may contain a colorant and a base material that holds the colorant. The colorant may be a pigment such as carbon black or titanium black. The base material may also contain a thermoplastic resin. The base material may contain a cured product of a curable resin composition.

[0129] The light-shielding layer 52 may also be formed by printing. The light-shielding layer 52 may also be formed by transfer. The thickness of the light-shielding layer 52 may be 1 μm or more, and may also be 3 μm or more. By setting a lower limit for the thickness of the light-shielding layer 52, the light-shielding layer 52 can ensure sufficient visible light-shielding properties. The thickness of the light-shielding layer 52 may be 100 μm or less, and may also be 20 μm or less.

[0130] In Figure 4In the example shown, the bonding layer 63 constitutes the second surface 40b of the decorative outer cover 40. The bonding layer 63 may also be provided for the purpose of improving the adhesion between the decorative outer cover 40 and the thermoplastic resin portion 32. The bonding layer 63 may also contain an adhesive material or an adhesion material. The adhesive material contained in the bonding layer 63 may contain one or more of an acrylic adhesive material, a rubber adhesive material, a polyurethane adhesive material, and a silicone adhesive material. The adhesion material contained in the bonding layer 63 may contain one or more of an acrylic adhesion material, a rubber adhesion material, a polyurethane adhesion material, and a silicone adhesion material.

[0131] From the viewpoint of ensuring the adhesion between the decorative outer cover 40 and the thermoplastic resin portion 32, the thickness of the bonding layer 63 may be 1 μm or more, and may also be 3 μm or more. The thickness of the bonding layer 63 may be 30 μm or less, and may also be 20 μm or less. By setting an upper limit on the thickness of the bonding layer 63, it is possible to easily remove a part of the light-shielding layer 52 located on the side of the first surface 40a with respect to the bonding layer 63 and form the recess 45. The bonding layer 63 may also be omitted from the decorative outer cover 40.

[0132] In Figure 4 the example shown, the thermoplastic resin portion 32 is joined to the decorative outer cover 40. The thermoplastic resin portion 32 is joined to the second surface 40b of the decorative outer cover 40. The thermoplastic resin portion 32 is also filled in the recess 45 of the decorative outer cover 40. The thermoplastic resin portion 32 is located between the decorative outer cover 40 and the light source 15 in the third direction D3. The thermoplastic resin portion 32 and the decorative outer cover 40 are stacked on each other in the third direction D3. As Figure 4 shown, a gap may also be provided between the thermoplastic resin portion 32 and the light source 15.

[0133] In Figure 4 the example shown, the thermoplastic resin portion 32 includes a base portion 32a and a protruding portion 32b protruding from the base portion 32a toward the decorative outer cover 40. The thermoplastic resin portion 32 is joined to the bonding layer 63 at the base portion 32a. The thermoplastic resin portion 32 is joined to the design layer 51, the base layer 61, and the light-shielding layer 52 at the protruding portion 32b. The thermoplastic resin portion 32 is located in the recess 45 of the decorative outer cover 40 at the protruding portion 32b.

[0134] In the example shown in the figure, the thermoplastic resin portion 32 is transparent. The light emitted from the light source 15 can pass through the thermoplastic resin portion 32. The thermoplastic resin portion 32 may also be colored. The thermoplastic resin portion 32 may also form the design shown by the decorative member 20.

[0135] The thermoplastic resin part 32 can also be produced by welding the injection resin 33 to the decorative outer cover 40. The details of the thermoplastic resin part 32 will be described later. It can also be formed by injecting the injection resin 33 into the cavity 130 formed in the injection molding apparatus 90.

[0136] The thickness of the thermoplastic resin part 32 is not particularly limited. From the viewpoint of stably maintaining the shape of the decorative member 20, the thickness of the thermoplastic resin part 32 ( Figure 4 the length in the third direction D3 in ) can be 0.5 mm or more, and can also be 1 mm or more. From the viewpoint of imparting a high visible light transmittance to the thermoplastic resin part 32, the thickness of the thermoplastic resin part 32 can be 10 mm or less, and can also be 5 mm or less. The thickness of the thermoplastic resin part 32 can also be greater than the thickness of the decorative outer cover 40.

[0137] For Figure 4 An example of the manufacturing method of the illustrated decorative member 20 will be described. When manufacturing the illustrated decorative member 20, first, a decorative sheet 35 is produced. By performing a forming process and laser etching on the produced decorative sheet 35, the decorative outer cover 40 is produced. By joining the thermoplastic resin part 32 to the produced decorative outer cover 40, the decorative member 20 is produced. The manufacturing method of the illustrated decorative member 20 will be described in detail below.

[0138] First, the production of the decorative outer cover 40 will be described. As described below, when producing the decorative outer cover 40, first, a decorative sheet 35 is produced. The decorative sheet 35 is a sheet-like member having a first surface 35a and a second surface 35b opposite to the first surface 35a. The first surface 35a of the decorative sheet 35 constitutes the first surface 40a of the decorative outer cover 40. The second surface 35b of the decorative sheet 35 constitutes the second surface 40b of the decorative outer cover 40. Next, by performing laser etching on the decorative sheet 35 from the second surface 35b side, the decorative outer cover 40 including the recess 45 is produced. In the present invention, the decorative sheet 35 in which the formation of the recess 45 is completed is referred to as the decorative outer cover 40. In the present invention, the decorative sheet 35 in which the formation of the recess 45 is not completed is not referred to as the decorative outer cover 40. When the decorative outer cover 40 includes a plurality of recesses 45, the decorative sheet 35 in which all of the plurality of recesses 45 are formed is referred to as the decorative outer cover 40. The decorative sheet 35 in which a part of the plurality of recesses 45 are formed is not referred to as the decorative outer cover 40.

[0139] Next, the production of the decorative sheet 35 will be described. First, a sheet material for forming the base layer 61 is prepared. The material and thickness of the base layer 61 are as described above. As Figure 5 shown, a design layer 51 is formed on one surface of the base layer 61. The method for forming the design layer 51, the material and thickness of the design layer 51 are as described above.

[0140] Next, asFigure 5 As shown, a surface layer 62 is formed on the design layer 51. The surface layer 62 can be formed by supplying a resin composition onto the design layer 51 to form a coating film of the resin composition and drying or curing the coating film. By forming the surface layer 62, as Figure 5 shown, the design layer 51 is located between the base layer 61 and the surface layer 62.

[0141] Next, as Figure 6 shown, a light-shielding layer 52 is formed on the surface of the base layer 61 opposite to the surface on which the design layer 51 and the surface layer 62 are formed. The method of forming the light-shielding layer 52, the material and thickness of the light-shielding layer 52 are as described above. By forming the light-shielding layer 52, as Figure 6 shown, the base layer 61 is located between the design layer 51 and the light-shielding layer 52.

[0142] Next, as Figure 6 shown, a bonding layer 63 is formed on the light-shielding layer 52. The bonding layer 63 can also be formed by supplying a resin composition onto the light-shielding layer 52 to form a coating film of the resin composition and drying the coating film. The material and thickness of the bonding layer 63 are as described above.

[0143] As described above, a decorative sheet 35 including the design layer 51 and the light-shielding layer 52 in sequence from the first surface 35a to the second surface 35b is obtained. In Figure 6 the example shown, the decorative sheet 35 includes the surface layer 62, the design layer 51, the base layer 61, the light-shielding layer 52, and the bonding layer 63 in sequence from the first surface 35a to the second surface 35b. The first surface 35a of the decorative sheet 35 is formed by the surface layer 62. The second surface 35b of the decorative sheet 35 is formed by the bonding layer 63. The manufacturing method of the decorative sheet 35 is not limited to the above example. For example, the manufacturing order of the surface layer 62, the design layer 51, the light-shielding layer 52, and the bonding layer 63 can also be changed.

[0144] Next, as Figures 7 to 9 shown, the decorative sheet 35 is subjected to a forming process. The forming process refers to a process of forming the decorative sheet 35 into a desired shape. The forming process can also be vacuum forming, pressure-air forming, bending forming, etc. The forming process can also be a preliminary forming process performed before injection molding. The decorative sheet 35 is plastically deformed by the forming process.

[0145] In the example shown, the decorative sheet 35 is vacuum formed using a vacuum forming device 85. The vacuum forming device 85 includes a heater 86 for heating the decorative sheet 35 and a vacuum forming die 87 for performing vacuum forming on the decorative sheet 35. The decorative sheet 35 is not limited to Figures 7 to 9 the example shown, and can also be plastically deformed by various forming methods such as pressure-air forming and bending forming.

[0146] In Figures 7 to 9In the vacuum forming of the decorative sheet 35 shown, first, as Figure 7 shown, the decorative sheet 35 is heated by the heater 86 of the vacuum forming device 85. By heating the decorative sheet 35, the decorative sheet 35 softens. When heating the decorative sheet 35, the vacuum forming die 87 can also be arranged near the decorative sheet 35. In the illustrated example, the decorative sheet 35 is located between the heater 86 and the vacuum forming die 87 in the third direction D33.

[0147] Next, as Figure 8 shown, the decorative sheet 35 is sucked. The decorative sheet 35 is vacuum-sucked from minute holes (not shown) provided in the vacuum forming die 87. Thereby, the decorative sheet 35 is adsorbed by the vacuum forming die 87. As a result, the decorative sheet 35 is formed into a shape matching the shape of the vacuum forming die 87. The decorative sheet 35 has a shape along the shape of the vacuum forming die 87. In the illustrated example, both end portions of the decorative sheet 35 in the first direction D1 have bent portions.

[0148] Next, in the Figure 8 shown state, the temperature of the decorative sheet 35 is lowered. The decorative sheet 35 is solidified in the formed shape.

[0149] Next, as Figure 9 shown, the decorative sheet 35 is removed from the vacuum forming die 87. In the illustrated example, the decorative sheet 35 is separated from the vacuum forming die 87 in the third direction D3.

[0150] Next, as Figure 10 shown, in the decorative sheet 35 removed from the vacuum forming die 87, unnecessary portions are trimmed. In the illustrated example, by trimming the unnecessary portions, a decorative sheet 35 having bent shapes at both end portions in the first direction D1 can be obtained.

[0151] As described above, the decorative sheet 35 is formed. Next, as Figure 11 shown, a part of the light-shielding layer 52 is removed from the second surface 35b side of the decorative sheet 35. By removing a part of the light-shielding layer 52, the decorative outer cover 40 including the recess 45 is manufactured. The removed part of the light-shielding layer 52 is located at a prescribed position of the decorative sheet 35 given a shape by forming. In the Figure 11 shown example, a part of the light-shielding layer 52 is removed by laser etching using the laser irradiation device 80. The method of removing a part of the light-shielding layer 52 is not limited to laser etching. For example, a part of the light-shielding layer 52 can also be removed by scraping the decorative sheet 35 from the second surface 35b side.

[0152] In the Figure 11In the example shown, the laser emitted from the laser irradiation device 80 is irradiated onto the decorative sheet 35 from the second surface 35b side of the decorative sheet 35. The laser enters the decorative sheet 35 from the second surface 35b side. Using the laser that enters the decorative sheet 35 from the second surface 35b side, a part of the bonding layer 63 and a part of the light-shielding layer 52 are removed.

[0153] The laser irradiation device 80 can remove components located at the focal position of the laser. The focal position of the laser can be controlled by a control device (not shown) electrically connected to the laser irradiation device 80. In Figure 11 the example shown, the control device can control the converging position of the laser according to the distances from the laser irradiation device 80 to the bonding layer 63 and the light-shielding layer 52, so as to remove a part of the bonding layer 63 and a part of the light-shielding layer 52.

[0154] By removing a part of the bonding layer 63 and a part of the light-shielding layer 52, as Figure 11 shown, an opening is provided in the second surface 35b of the decorative sheet 35. After laser etching of the decorative sheet 35, the decorative sheet 35 includes the design layer 51 in a part that overlaps with the part where the light-shielding layer 52 has been removed in the third direction D3. By irradiating the laser onto the decorative sheet 35 from the second surface 35b side, it is possible to suppress the laser from irradiating onto the design layer 51. Thus, it is possible to suppress the design layer 51 from being accidentally removed.

[0155] The laser used in laser etching is not particularly limited. Lasers emitted from various types of laser light sources can be used. The wavelength of the laser used in laser etching is also not particularly limited. The laser can have a wavelength in the visible light region or can have a wavelength in the infrared region. As the laser, a laser with a high absorption rate in the light-shielding layer 52 can also be used. The absorption rate of the laser in the light-shielding layer 52 can be 5% or more, or can be 10% or more. Regarding the upper limit value of the absorption rate of the laser in the light-shielding layer 52, there is no particular limitation. The absorption rate of the laser in the light-shielding layer 52 can be 100% or less, or can be 95% or less. As the laser, a laser with a low absorption rate in the base layer 61 can also be used.

[0156] As described above, the decorative outer cover 40 including the recess 45 is manufactured. The manufactured decorative outer cover 40 includes the recess 45 that is open on the second surface 40b.

[0157] In addition, the manufacturing method of the decorative outer cover 40 can also be different from the example shown and does not include the above-described process of forming the decorative sheet 35. The decorative outer cover 40 can also be manufactured by removing a part of the light-shielding layer 52 from the second surface 35b of the unformed decorative sheet 35.

[0158] Next, the decorative member 20 is manufactured using the manufactured decorative outer cover 40. First, as Figure 12As shown, an injection molding apparatus 90 is prepared. The injection molding apparatus 90 includes a molding die 100. In Figure 12 the example shown, the molding die 100 includes a first molding die 110 and a second molding die 120. In the example shown, the first molding die 110 and the second molding die 120 face each other in the third direction D3.

[0159] As Figure 12 and Figure 15 shown, the molding die 100 can be in an open mold state in which the first molding die 110 and the second molding die 120 are separated from each other. As Figure 13 and Figure 14 shown, the molding die 100 can be in a closed mold state in which the first molding die 110 and the second molding die 120 are in contact with each other. The first molding die 110 and the second molding die 120 can move relative to each other in a manner of approaching each other from the open mold state to the closed mold state. The first molding die 110 and the second molding die 120 can move relative to each other in a manner of separating from each other from the closed mold state to the open mold state.

[0160] As Figure 14 shown, when the molding die 100 is in the closed mold state, a cavity 130 is formed between the first molding die 110 and the second molding die 120. The molding die 100 has a gate 140 communicating with the cavity 130. In the example shown, the gate 140 is provided in the second molding die 120. The gate 140 is connected to a supply device (not shown) of injection resin 33. The injection resin 33 is supplied to the cavity 130 through the gate 140.

[0161] As Figure 12 shown, a decorative outer cover 40 is conveyed into the molding die 100. The decorative outer cover 40 conveyed into the molding die 100 is received in the cavity 130 in the molding die 100. In the example shown, the decorative outer cover 40 is held by the first molding die 110 in such a manner that the first surface 40a is in contact with the first molding die 110. In the state where the decorative outer cover 40 is held by the first molding die 110, the second surface 40b faces the second molding die 120.

[0162] Next, as Figure 13 shown, the molding die 100 is set to the closed mold state. In the molding die 100 that has become the closed mold state, a cavity 130 is formed between the first molding die 110 and the second molding die 120. The decorative outer cover 40 is received in the cavity 130. In the state where the decorative outer cover 40 is held by the molding die 100, the second surface 40b faces the cavity 130.

[0163] Next, as Figure 14As shown, the molten injection resin 33 is injected into the chamber 130 through the gate 140. The injection resin 33 is cooled within the chamber 130, fused to the decorative outer cover 40, and solidified. The thermoplastic resin part 32 joined to the decorative outer cover 40 is formed by the solidified injection resin 33.

[0164] Next, as Figure 15 shown, the molding die 100 is set in the open mold state. In the molding die 100 in the open mold state, the first molding die 110 and the second molding die 120 are separated from each other. The decorative part 20 including the decorative outer cover 40 and the thermoplastic resin part 32 joined to the decorative outer cover 40 is taken out from the chamber 130. As described above, the decorative part 20 including the decorative outer cover 40 and the thermoplastic resin part 32 is obtained. Further, by overlapping the light source 15 on the decorative part 20, the Figures 1 to 4 shown display system 10 is obtained. At this time, the thermoplastic resin part 32 is located between the light source 15 and the decorative outer cover 40.

[0165] However, in the conventional manufacturing method of the decorative part, the decorative outer cover formed with the through portion is subjected to the forming process. According to this manufacturing method, during the forming process of the decorative outer cover, as the decorative outer cover deforms, the position and shape of the through portion also change significantly. On the other hand, it is difficult to determine the position and shape of the through portion before the forming process in consideration of the position shift and shape change of the through portion accompanying the forming process. Therefore, in the conventional decorative outer cover and decorative part, it is difficult to provide the through portion having the desired shape at the desired position. As a result, in the conventional decorative outer cover and conventional decorative part, it is sometimes impossible to display a desired pattern using the light passing through the through portion.

[0166] The manufacturing method of the decorative part 20 of the present embodiment includes: a step of performing a forming process on the decorative sheet 35 including the light-shielding layer 52; a step of manufacturing the decorative outer cover 40 including the recess 45 from the decorative sheet 35 by removing a part of the light-shielding layer 52 from the decorative sheet 35; and a step of forming the thermoplastic resin part 32 joined to the decorative outer cover 40. According to this manufacturing method, the recess 45 forming the through portion 41 of the decorative outer cover 40 is formed after the forming process of the decorative sheet 35. Thereby, it is possible to suppress the position shift of the through portion 41 and the shape deformation of the through portion 41 caused by the forming process of the decorative sheet 35. In addition, since the shape is given to the decorative sheet 35 by the forming process, the processing position of the recess 45 can be easily and highly accurately positioned with respect to the decorative sheet 35. Therefore, in the decorative part 20 manufactured by this manufacturing method, a desired pattern can be displayed using the light passing through the through portion.

[0167] The operation of the illustrated display system 10 will be described.

[0168] When the light source 15 is in the off state, as Figure 2 shown, the decorative member 20 covering the light source 15 is observed. The decorative member 20 shows the design of the decorative outer cover 40. The design of the decorative outer cover 40 is formed by the design layer 51. The design layer 51 is located at positions straddling the transmissive portion 41 and the light-shielding portion 42 of the decorative outer cover 40. Thus, the decorative outer cover 40 can show the design formed in the design layer 51 both in the transmissive portion 41 and the light-shielding portion 42. That is, the decorative member 20 can also show the design in the transmissive portion 21 overlapping with the light source 15. In addition, by using the design layer 51 covering both the transmissive portion 41 and the light-shielding portion 42, the light source 15 overlapping with the transmissive portion 21 of the decorative member 20 can be effectively shielded.

[0169] When the light source 15 is in the on state, light is emitted from the light source 15 toward the decorative member 20. The light incident on the decorative member 20 travels toward the decorative outer cover 40 in the thermoplastic resin portion 32. The light traveling toward the decorative outer cover 40 is incident on the transmissive portion 41 or the light-shielding portion 42. The light incident on the light-shielding portion 42 is absorbed by the light-shielding layer 52 after passing through the bonding layer 63. The light incident on the transmissive portion 41 passes through the thermoplastic resin portion 32 located in the recess 45 and reaches the base layer 61. The light reaching the base layer 61 passes through the base layer 61, the design layer 51, and the surface layer 62, and is emitted from the display surface 11 formed by the first surface 40a of the decorative outer cover 40. Thus, the light incident on the decorative member 20 is emitted from the transmissive portion 21 formed by the transmissive portion 41 of the decorative outer cover 40. Therefore, when the light source 15 is in the on state, as Figure 3 shown, the pattern of the transmissive portion 21 is displayed. In the illustrated example, a cross, a triangle, and a quadrilateral are displayed.

[0170] In addition, the existing decorative outer cover disclosed in JP2017-65168A includes: a decorative portion including a design layer, and a non-decorative portion not including a design layer. In the existing decorative outer cover, the decorative portion shows the design. The non-decorative portion allows the light of the light source disposed on the back surface of the decorative outer cover to pass through. In the non-decorative portion, the design layer is removed. The design layer is only provided in the decorative portion. When observing the existing decorative outer cover, even when the light source is off, the non-decorative portion can be observed from the outside as a portion where the design layer is interrupted. Since the non-decorative portion can be observed from the outside, the appearance design of the decorative outer cover is reduced. In addition, in the existing decorative outer cover, in the application object of the decorative outer cover, it is not possible to sufficiently ensure the harmony and unity with the surrounding environment.

[0171] The decorative outer cover 40 of the present embodiment sequentially includes a design layer 51 and a light-shielding layer 52 from the first surface 40a to the second surface 40b. The decorative outer cover 40 includes a recess 45 that opens on the second surface 40b. The recess 45 penetrates the light-shielding layer 52 but does not penetrate the design layer 51. When the light source 15 is disposed on the second surface 40b side of the decorative outer cover 40, the decorative outer cover 40 can transmit the light from the light source 15 through the transmissive portion 41 formed by the recess 45. The design layer 51 is provided to cover the transmissive portion 41 without interruption in the transmissive portion 41 formed by the recess 45. Therefore, when the light source is turned off, the presence of the transmissive portion 41 is not easily noticed, and moreover, the design of the design layer 51 can be displayed on the portion on the transmissive portion 41 in the same manner as other portions. Thereby, the appearance designability of the decorative outer cover 40 can be improved. As a result, the decorative member 20 including the decorative outer cover 40 can also ensure harmony and unity with the surrounding environment through the improved appearance design performance of the decorative outer cover 40.

[0172] In Figures 1 to 4 the example shown, the decorative outer cover 40 includes a base layer 61 between the design layer 51 and the light-shielding layer 52. The bottom 46 of the recess 45 is formed by the base layer 61. According to this specific example, the design layer 51 and the light-shielding layer 52 can be separated from each other in the stacking direction ( Figure 4 the third direction D3 in). Thereby, when removing the light-shielding layer 52 by laser etching, scraping, etc., it is possible to suppress the design layer 51 from being accidentally removed. For example, consider the case where the laser is converged on the light-shielding layer 52 in order to remove the light-shielding layer 52. In this case, the design layer 51 is separated from the focus of the laser, thereby suppressing the temperature rise of the design layer 51 caused by the laser. By suppressing the temperature rise of the design layer 51, it is possible to suppress the design layer 51 from being removed. Therefore, according to this specific example, the appearance designability of the decorative outer cover 40 can be stably improved.

[0173] In Figure 4In the example shown, the display system 10 includes a decorative member 20 and a light source 15 facing the decorative member 20. The decorative member 20 includes a decorative outer cover 40, which includes a first surface 40a and a second surface 40b; and a thermoplastic resin portion 32, which is joined to the second surface 40b of the decorative outer cover 40. The thermoplastic resin portion 32 is located between the decorative outer cover 40 and the light source 15 in a third direction. The display surface 11 is formed by the first surface 40a of the decorative outer cover 40. The decorative outer cover 40 includes a light-shielding layer 52. The decorative outer cover 40 includes a recess 45 that opens on the second surface 40b and penetrates the light-shielding layer 52. In this display system 10, using the light that has passed through the transmissive portion 41 among the light reaching the decorative outer cover 40, the pattern of the transmissive portion 41 can be observed on the display surface 10a. The light emitted from the light source 15 passes through the thermoplastic resin portion 32 and reaches the decorative outer cover 40. That is, the light that passes through the transmissive portion 41 and displays the display pattern reaches the display surface 10a without passing through the thermoplastic resin portion 32. The thermoplastic resin portion 32 is a layer with a relatively thick thickness, and the light will diffuse during its advancement within the thermoplastic resin portion 32. Therefore, the light that forms the display pattern and has passed through the transmissive portion 41 can reach the display surface 10 without significant diffusion. Thus, the display system 10 can clearly display the outline of the desired display pattern.

[0174] In one embodiment described above, the decorative outer cover 40 has a first surface 40a and a second surface 40b opposite to the first surface 40a. The decorative outer cover 40 sequentially includes a design layer 51 and a light-shielding layer 52 from the first surface 40a toward the second surface 40b. The decorative outer cover 40 includes a recess 45 that opens on the second surface 40b. The recess 45 penetrates the light-shielding layer 52 and does not penetrate the design layer 51. According to this decorative outer cover 40, the design layer 51 is arranged to continuously cover the transmissive portion 41 without interruption by the recess 45. Therefore, when the light source is turned off, the presence of the transmissive portion 41 is not easily noticed, and moreover, the appearance design of the design layer 51 can be displayed in the same manner as other portions at the portion located on the transmissive portion 41. Thus, the appearance designability of the decorative outer cover 40 can be improved in the view from the first surface 40a side.

[0175] One embodiment has been described with reference to specific examples, but the above specific examples do not limit one embodiment. The above one embodiment can be implemented with various other specific examples, and various omissions, substitutions, changes, additions, etc. can be made within the scope not departing from its gist.

[0176] Hereinafter, mainly with reference to Figures 16 to 23 , an example of a modification will be described. Among them, Figure 16 is a cross-sectional view showing a modified example of the decorative member 20. Figures 17 to 23 is for explaining Figure 16A diagram showing an example of a method for manufacturing the decorative member 20. In the following description and the accompanying drawings used in the following description, for parts that can be configured in the same manner as the above specific example, the same reference numerals as those used for the corresponding parts in the above specific example are used, and repeated descriptions are omitted.

[0177] In a specific example of the above decorative outer cover 40, the base layer 61 is located between the design layer 51 and the light-shielding layer 52. However, it is not limited to this. As Figure 16 shown, the base layer 61 may also be located on the side of the first surface 40a closer to the design layer 51. That is, the design layer 51 may also be located between the base layer 61 and the light-shielding layer 52. The decorative outer cover 40 may sequentially include the base layer 61, the design layer 51, and the light-shielding layer 52 from the first surface 40a to the second surface 40b.

[0178] In a specific example of the above decorative outer cover 40, the design layer 51 and the light-shielding layer 52 are separated from each other in the stacking direction with the base layer 61 therebetween. However, it is not limited to this. As Figure 16 shown, the design layer 51 and the light-shielding layer 52 may also be adjacent to each other in the stacking direction.

[0179] In a specific example of the above decorative outer cover 40, the bottom 46 of the recess 45 is formed by the base layer 61. In the above decorative outer cover 40, the recess 45 is not formed in the design layer 51. In the above recess 45, neither the bottom 46 nor the wall portion 48 is formed by the design layer 51. Not limited to the above example, as Figure 16 shown, the bottom 46 of the recess 45 may also be formed by the design layer 51. In Figure 16 the recess 45 shown, the wall portion 48 is not formed by the design layer 51.

[0180] In a specific example of the above decorative outer cover 40, the first surface 40a of the decorative outer cover 40 is flat. However, it is not limited to this. The decorative outer cover 40 may also have a concavo-convex shape 47 on the first surface 40a. As Figure 16 shown, a concavo-convex surface may also be formed on the first surface 40a by the concavo-convex shape 47. In the illustrated example, the concavo-convex shape 47 is formed in the base layer 61. By the decorative outer cover 40 having the concavo-convex shape 47, the decorative member 20 has a concavo-convex shape 27 on the first surface 20a.

[0181] In Figure 16 the example shown, the concavo-convex shape 47 is composed of a convex portion 47a and a concave portion 47b. The convex portion 47a and the concave portion 47b may also be alternately arranged in one direction. In the illustrated example, the convex portion 47a and the concave portion 47b are alternately arranged in the first direction D1 as the arrangement direction.

[0182] In Figure 16In the example shown, the height difference between the convex portion 47a and the concave portion 47b may also be smaller than the average thickness of the base layer 61 having the concavo-convex shape 47. In addition, in order to determine the "average thickness of the base layer", a decorative outer cover 40 having a length of 50 μm in a direction (for example, Figure 16 the first direction D1 in Figure 16 ) orthogonal to the third direction D3 in the stacking direction is used. The "average thickness of the base layer" is calculated as the average value when measuring the length of the base layer 61 in the stacking direction of the decorative outer cover 40 at 20 arbitrary positions in the cross section of the decorative outer cover 40. The "height difference between the convex portion and the concave portion" is calculated as the difference between the thickness having the fifth largest value and the thickness having the fifth smallest value among the thicknesses of the base layer 61 at the above-mentioned 20 arbitrary positions. The height difference between the convex portion 47a and the concave portion 47b may be 5 μm or more and 30 μm or less.

[0183] A pattern may also be represented on the first surface 40a of the decorative outer cover 40 by the concavo-convex shape 47. Linear patterns such as a fine line pattern and a spiral line pattern may also be represented by the concavo-convex shape 47. According to this specific example, the texture of the decorative outer cover 40 observed from the first surface 40a can be changed. Thereby, the design property of the decorative outer cover 40 can be improved.

[0184] Figure 16 The decorative outer cover 40 shown may also be made of a decorative sheet 35 having a concavo-convex shape forming the concavo-convex shape 47 of the decorative outer cover 40 on the first surface 35a. Laser may also be irradiated on the decorative sheet 35 from the second surface 35b side opposite to the first surface 35a having the concavo-convex shape. In the case of irradiating laser from the second surface 35b side, scattering of the laser on the surface of the decorative sheet 35 can be suppressed as compared with the case of irradiating laser from the first surface 35a side. Thereby, the focusing position of the laser irradiated on the decorative sheet 35 can be easily adjusted, and the light-shielding layer 52 can be removed at a desired position. Therefore, by manufacturing the decorative outer cover 40 in this way, the concave portion 45 can be stably formed in the decorative outer cover 40 regardless of the concavo-convex shape 47 of the first surface 40a.

[0185] The above-described manufacturing method of the decorative component is only an example. The decorative component may also be manufactured by other manufacturing methods. Hereinafter, other examples of the manufacturing method will be described. In the manufacturing method described below, as an example, manufacturing Figure 16The decorative member 20 shown. In this manufacturing method, the decorative sheet 35 is formed using the first forming die 110. By forming a recess 45 in the decorative sheet 35 disposed in the first forming die 110, the decorative outer cover 40 is produced. Further, in a state where the decorative outer cover 40 is disposed in the first forming die 110, the second forming die is overlapped on the first forming die 110. By injecting a thermoplastic resin into the cavity 130 formed between the first forming die 110 and the second forming die, a thermoplastic resin portion 32 joined to the decorative outer cover 40 is formed. Hereinafter, a detailed description will be given.

[0186] Produce the decorative sheet 35. The design layer 51 and the light-shielding layer 52 are overlapped on one surface of the base layer 61. The decorative sheet 35 is produced in such a manner that the design layer 51 is located between the light-shielding layer 52 and the base layer 61. The produced decorative sheet 35 sequentially includes the base layer 61, the design layer 51, and the light-shielding layer 52 from the first surface 35a to the second surface 35b. The first surface 35a of the decorative sheet 35 is constituted by the base layer 61. The second surface 35b of the decorative sheet 35 is constituted by the light-shielding layer 52.

[0187] Next, the decorative sheet 35 is formed. An injection molding apparatus 90 is used for forming the decorative sheet 35. In Figure 17 and Figure 18 In the example shown, the decorative sheet 35 is formed using the first forming die 110 in the open die state of the forming die 100. The first forming die 110 has a contact surface 110a opposed to the decorative sheet 35. The decorative sheet 35 can also be formed by vacuum forming as described with reference to Figure 17 and Figure 18 below.

[0188] In Figure 17 and Figure 18 In the example shown, the first forming die 110 has a forming recess 111 in the central portion in the first direction D1.

[0189] In Figure 17 and Figure 18 In the example shown, a plurality of first suction holes 112 are provided in the forming recess 111. The plurality of first suction holes 112 open on the contact surface 110a of the first forming die 110. The first suction holes 112 are connected to a suction pump (not shown). The suction pump sucks the air in the first suction holes 112.

[0190] In Figure 17 and Figure 18 In the example shown, the first forming die 110 has a groove 113 at a position outside the forming recess 111. In other words, the groove 113 is located at a position farther from the center of gravity of the first forming die 110 than the forming recess 111.

[0191] InFigure 17 and Figure 18 In the example shown in Figure 18 , a plurality of second suction holes 114 are provided in the groove 113. The plurality of second suction holes 114 are connected to a suction pump (not shown). The suction pump sucks the air inside the second suction holes 114. In addition, as the pump for sucking the air inside the second suction holes 114, a pump different from the pump for sucking the air inside the first suction holes 112 may also be used.

[0192] In Figure 19 the example shown in Figure 19 , a concavo-convex shape 110s corresponding to the concavo-convex shape 47 of the decorative outer cover 40 is formed on the contact surface 110a. The concavo-convex shape 110s can also be formed by various methods such as sandblasting.

[0193] As Figure 17 shown, the decorative sheet 35 is supplied to the first forming die 110 having the above structure. In the example shown, the decorative sheet 35 contacts the first forming die 110 at a portion other than the forming recess 111. The decorative sheet 35 contacts the contact surface 110a of the first forming die 110 from the first surface 35a. The opening of the groove 113 is closed by the decorative sheet 35.

[0194] Next, the air inside the second suction holes 114 is sucked by a suction pump (not shown). The second suction holes 114 communicate with the groove 113. The opening of the groove 113 is closed by the decorative sheet 35. Thus, the decorative sheet 35 is sucked by the groove 113. As a result, in Figure 17 the state shown in Figure 17 , the decorative sheet 35 is held on the contact surface 110a of the first forming die 110. In this state, the space between the decorative sheet 35 and the first forming die 110 is sealed. In this state, the decorative sheet 35 may also be recessed into the groove 113.

[0195] After that, the decorative sheet 35 sucked by the second suction holes 114 is further sucked through the first suction holes 112. The suction pump connected to the first suction holes 112 sucks the air inside the first suction holes 112 and the air between the forming recess 111 and the decorative sheet 35. Thus, as Figure 18 shown, the portion of the decorative sheet 35 opposite to the forming recess 111 is attracted toward the contact surface 110a forming the forming recess 111. The decorative sheet 35 can contact the contact surface 110a forming the forming recess 111 at the first surface 35a.

[0196] As described above, the decorative sheet 35 is formed using the first forming die 110. In addition, in Figure 18 the state shown in Figure 18 , the concavo-convex shape 110s formed on the contact surface 110a may also be transferred to the first surface 35a of the decorative sheet 35. Or, as Figure 19 shown in Figure 19 , the concavo-convex shape 110s formed on the contact surface 110a may not be transferred to the first surface 35a of the decorative sheet 35.

[0197] Next, the decorative outer covering 40 is produced from the decorative sheet 35 disposed in the first forming die 110. Specifically, as Figure 19 shown, in the decorative sheet 35 held by the first forming die 110, a part of the light-shielding layer 52 is removed from the second surface 35b side. As Figure 19 shown, the light-shielding layer 52 can also be removed by laser etching.

[0198] In Figure 19 the example shown, the laser emitted from the laser irradiation device 80 irradiates the decorative sheet 35. The laser enters the decorative sheet 35 from the second surface 35b side. A part of the light-shielding layer 52 is removed by the laser that enters the decorative sheet 35 from the second surface 35b side. The design layer 51 is exposed from the part where the light-shielding layer 52 has been removed. The focusing position of the laser can also be adjusted according to the distance from the laser irradiation device 80 to the light-shielding layer 52 to remove a part of the light-shielding layer 52. By removing a part of the light-shielding layer 52, as Figure 19 shown, an opening is provided in the second surface 35b of the decorative sheet 35.

[0199] In the process of forming the recess 45, the decorative sheet 35 is held by the first forming die 110. Therefore, the processing machine for forming the recess 45, the laser irradiation device 80 in the illustrated example, can be accurately positioned relative to the decorative sheet 35 by operating with the first forming die 110 as a reference. Therefore, a recess 45 having a desired shape can be accurately formed at a desired position of the decorative sheet 35 that has been given a shape by forming.

[0200] As described above, the decorative outer covering 40 including the recess 45 is produced from the decorative sheet 35 disposed in the first forming die 110. The produced decorative outer covering 40 includes a recess 45 that is open at the second surface 40b.

[0201] Next, a thermoplastic resin part 32 that is joined to the decorative outer covering 40 is formed. First, from Figure 20 the state shown, the second forming die 120 is overlapped with the first forming die 110. By bringing the second forming die 120 closer to the first forming die 110 from Figure 20 the state shown, as Figure 21 shown, the second forming die 120 is overlapped with the first forming die 110. That is, the forming die 100 is in a closed die state. In the closed die state, a cavity 130 is formed between the first forming die 110 and the second forming die 120. In the closed die state, the decorative outer covering 40 is housed in the cavity 130. In Figure 21 the state shown, the first surface 40a of the decorative outer covering 40 faces the first forming die 110. The second surface 40b of the decorative outer covering 40 faces the second forming die 120.

[0202] After that, as Figure 21 shown, the injection molding resin 33 is injected into the chamber 130 through the gate 140. Next, the injection molding resin 33 cools in the chamber 130, fuses with the decorative outer cover 40, and solidifies. The thermoplastic resin portion 32 joined to the decorative outer cover 40 is formed by the solidified injection molding resin 33.

[0203] In the illustrated example, the decorative outer cover 40 is pressed against the injection molding resin 33 injected into the chamber 130 by the first molding die 110. The first surface 40a formed by the base layer 61 of the decorative outer cover 40 pressed against the first molding die 110 is strongly pressed against the contact surface 110a of the first molding die 110. As a result, the uneven shape 110s formed on the contact surface 110a is transferred to the first surface 40a of the decorative outer cover 40. According to this specific example, the decorative outer cover 40 having the uneven shape 47 on the first surface 40a can be efficiently manufactured.

[0204] After the decorative sheet thermoplastic resin portion 32 is formed, in the first molding die 110, the suction of the decorative outer cover 40 from the first suction hole 112 and the suction of the decorative outer cover 40 from the second suction hole 114 are stopped. As a result, the movement restriction of the decorative outer cover 40 with respect to the first molding die 110 is released.

[0205] Next, as Figure 23 shown, the first molding die 110 and the second molding die 120 are separated from each other. That is, the molding die 100 is in the open mold state. The decorative member 20 is separated from the second molding die 120 while being held by the second molding die 120.

[0206] As described above, the decorative member 20 including the decorative outer cover 40 and the thermoplastic resin portion 32 joined to the decorative outer cover 40 is manufactured. In the manufactured decorative member 20, as described with reference to Figure 10 above, unnecessary portions can also be trimmed.

[0207] In reference to Figures 17 to 21In the method for manufacturing the above-described decorative member, the decorative sheet 35 is formed by the first forming die 110. The decorative cover member 40 is produced from the decorative sheet 35 disposed in the first forming die 110. With the decorative cover member 40 disposed in the first forming die 110, the second forming die 120 is overlapped with the first forming die 110. By injecting a thermoplastic resin into the cavity 130 disposed between the first forming die 110 and the second forming die 120, the thermoplastic resin portion 32 joined to the decorative cover member 40 is formed. According to this specific example, the decorative sheet 35 or the decorative cover member 40 after being formed and processed by the first forming die 110 is maintained in the state of being disposed on the first forming die 110, and the formation of the recess 45 and the injection molding are carried out. Therefore, the positioning of the processing position with respect to the decorative sheet 35 or the decorative cover member 40 having a given shape can be greatly simplified, and the formation of the recess 45 and the injection molding can be carried out with high precision. Therefore, according to this example, the decorative member 20 can be manufactured stably and with high precision.

[0208] In a specific example of the above-described decorative cover member 40, the base layer 61 is a single layer. However, it is not limited thereto. As Figure 24 shown, the base layer 61 may also include a first base layer 611 and a second base layer 612. In the illustrated example, the first base layer 611 is joined to the second base layer 612 on the surface opposite to the surfaces of the support surface layer 62 and the design layer 51. The second base layer 612 is joined to the first base layer 611 on the surface opposite to the surface of the support light-shielding layer 52.

[0209] As described below with reference to Figure 25 the first base layer 611 and the second base layer 612 may also be joined to each other by thermal lamination. In the illustrated example, the first decorative sheet 351 and the second decorative sheet 352 are conveyed between the first roller 201 and the second roller 202. The first decorative sheet 351 sequentially includes the surface layer 62, the design layer 51, and the first base layer 611 from the first surface 351a to the second surface 351b. The second decorative sheet 352 sequentially includes the second base layer 612, the light-shielding layer 52, and the bonding layer 63 from the first surface 352a to the second surface 352b. Any one of the first roller 201 and the second roller 202 is heated, for example, by a built-in heating device (not shown). The first roller 201 and the second roller 202 may also be heated by a heating device (not shown).

[0210] In Figure 25In the example shown, the first decorative sheet 351 and the second decorative sheet 352 are pressed against each other by the first roller 201 and the second roller 202. The first decorative sheet 351 is welded to the first surface 352b of the second decorative sheet 352 from the second surface 351b. The second decorative sheet 352 is welded to the second surface 351b of the first decorative sheet 351 from the first surface 352a. As described above, the decorative sheet 35 including the first base layer 611 and the second base layer 612 is produced. In addition, the first base layer 611 and the second base layer 612 are not limited to the above-mentioned thermal lamination, and can be joined to each other by, for example, dry lamination.

[0211] The base layer 61 of the decorative cover member 40 located on the first surface 40a side relative to the design layer 51 is not limited to Figure 16 the example shown. As Figure 26 shown, the decorative cover member 40 may sequentially include a base layer 61, a design layer 51, an intermediate layer 53, and a light-shielding layer 52 from the first surface 40a to the second surface 40b. The decorative cover member 40 may also include an intermediate layer 53 located between the design layer 51 and the light-shielding layer 52. In the illustrated decorative cover member 40, the laser absorption rate in the intermediate layer 53 may be lower than the laser absorption rate in the light-shielding layer 52. The laser absorption rate in the intermediate layer 53 may be 3% or less, or may be 1% or less.

[0212] Figure 26 The illustrated decorative cover member 40 is made of the decorative sheet 35. In the decorative sheet 35, the design layer 51 is located between the base layer 61 and the light-shielding layer 52. In the decorative sheet 35, the intermediate layer 53 is located between the design layer 51 and the light-shielding layer 52. The illustrated recess 45 is formed by a portion where the light-shielding layer 52 is removed. The illustrated recess 45 does not penetrate the intermediate layer 53. The illustrated recess 45 does not penetrate the design layer 51. A part of the light-shielding layer 52 is removed using laser light irradiated from the second surface 35b side of the decorative sheet 35. Different from the illustrated decorative cover member 40, a part of the intermediate layer 53 may also be removed by laser. The recess 45 may also be formed by a portion where the light-shielding layer 52 and the intermediate layer 53 are removed.

[0213] By disposing the above-mentioned intermediate layer 53 between the design layer 51 and the light-shielding layer 52, the design layer 51 and the light-shielding layer 52 can be spaced apart in the first direction D1. It is possible to prevent the design layer 51 from being accidentally removed by laser light irradiated from the second surface 35b side of the decorative sheet 35. Therefore, the decorative cover member 40 including the intermediate layer 53 can stably display the design formed by the design layer 51.

[0214] The intermediate layer 53 may also be formed by printing. The thickness of the intermediate layer 53 may be 1 μm or more, or may be 3 μm or more. The thickness of the intermediate layer 53 may be 30 μm or less, or may be 20 μm or less.

[0215] The intermediate layer 53 may also contain a resin. The intermediate layer 53 may also contain a thermoplastic resin. The thermoplastic resin may contain one or more of an acrylic resin, a polyester resin, and a vinyl chloride-vinyl acetate copolymer resin.
