Embodiments for Carrying Out the Invention

[0011] FIG. 1 is a schematic view showing an example of the cross-sectional structure of the laminated member 1. The laminated member 1 is a member in which a plurality of inkjet layers are laminated. As shown in FIG. 1, the laminated member 1 includes, for example, a base material 10 (also referred to as a target base material 10) on which an inkjet layer is to be formed, and an inkjet layer 20 formed on the base material 10. The inkjet layer 20 has, for example, a first inkjet layer 21 provided on the target base material 10 and a second inkjet layer 22 laminated on the first inkjet layer 21.

[0012] The inkjet layer is an ink layer printed by inkjet printing and can also be referred to as an inkjet printing layer. It can also be said that the inkjet layer is an ink layer printed by an inkjet printing apparatus. In inkjet printing, ink droplets are sprayed from an inkjet head onto an object while the position of the inkjet head that discharges the ink droplets is automatically controlled by a computer, and an ink layer is formed on the object.

[0013] The target base material 10 has a black-colored portion (also referred to as a black-colored part) 11. The black-colored portion 11 has a first surface 12, and the inkjet layer 20 is provided on the first surface 12. The first surface 12 can also be said to be the region of the surface of the black-colored portion 11 where the inkjet layer 20 is provided. The target base material 10 can be any member as long as it can be inkjet-printed on the first surface 12. For example, the target base material 10 may be a case (also referred to as a housing) that constitutes the exterior of a device.

[0014] The black-colored portion 11 may be a layered, film-like or sheet-like portion with a relatively small thickness or almost no thickness, or a three-dimensional portion with a relatively large thickness. The black-colored portion 11 may be an ink layer formed by inkjet printing or the like, a painted coating film, or a molded portion molded from a black-colored material (for example, resin).

[0015] All of the target substrate 10 may be the black-colored portion 11, or a part of the target substrate 10 may be the black-colored portion 11. That is, the color of the entire area of the target substrate 10 may be black, or the color of a part of the target substrate 10 may be black.

[0016] The first inkjet layer 21 is a white inkjet layer. That is, the color of the first inkjet layer 21 is white. The first inkjet layer 21 is provided on the first surface in the black-colored portion 11. The first inkjet layer 21 and the second inkjet layer 22 are laminated on the first surface.

[0017] Here, the black color system in the present disclosure is a color that satisfies any one of the first condition and the second condition regarding the R value, G value, and B value in the RGB color code. Also, the white color system in the present disclosure is a color that satisfies any one of the third condition, the fourth condition, and the fifth condition regarding the R value, G value, and B value in the RGB color code. In the RGB color code, each of the R value, G value, and B value is represented by 8 bits, and each of the R value, G value, and B value takes an integer value between 0 and 255 in decimal notation. The R value, G value, and B value used in the description of the first condition to the fifth condition described below are values in decimal notation.

[0018] The first condition regarding the black color system is that the sum of the R value, G value, and B value in the RGB color code is 204 or less, and the absolute value of the difference between any two values selected from the R value, G value, and B value is 102 or less. When the sum of the R value, G value, and B value of a certain color is 204 or less, the absolute value of the difference between the R value and G value of the certain color is 102 or less, the absolute value of the difference between the R value and B value of the certain color is 102 or less, and the absolute value of the difference between the G value and B value of the certain color is 102 or less, the certain color is a black color system.

[0019] The second condition regarding black colors is that the sum of the R value, G value, and B value in the RGB color code is 384 or less, and for any combination of two values selected from the R value, G value, and B value, the absolute value of the difference between the two values is 10 or less. If the sum of the R value, G value, and B value of a certain color is 384 or less, the absolute value of the difference between the R value and G value of the certain color is 10 or less, the absolute value of the difference between the R value and B value of the certain color is 10 or less, and the absolute value of the difference between the G value and B value of the certain color is 10 or less, then the certain color is a black color.

[0020] The third condition regarding white colors is that the sum of the R value, G value, and B value in the RGB color code is 730 or more. The fourth condition is that the sum of the R value, G value, and B value in the RGB color code is 710 or more, and for any combination of two values selected from the R value, G value, and B value, the absolute value of the difference between the two values is 41 or less. The fifth condition is that the sum of the R value, G value, and B value in the RGB color code is 672 or more, and for any combination of two values selected from the R value, G value, and B value, the absolute value of the difference between the two values is 10 or less.

[0021] The colors of the base material 10 and the inkjet layer 20 may be evaluated based on the results measured according to JIS Z8722:2009. Specifically, it may be evaluated by a spectroscopic color measurement method using a first type of spectrocolorimeter defined in 5.2.1 of the above JIS standard.

[0022] Also, it may be simply evaluated using a color sample book. Using a color sample book having 500 or more color samples (for example, "JIS Standard Color Chips Glossy Edition (9th Edition)" (Japan Color Research Institute, Incorporated Foundation)), the colors of the base material 10 and the inkjet layer 20 are compared with the color samples. As a result of the comparison, the color sample closest to the colors of the base material 10 and the inkjet layer 20 is extracted. The R value, G value, and B value in the RGB color code in the extracted color sample are estimated as the R value, G value, and B value in the RGB color code in the base material 10 and the inkjet layer 20.

[0023] The ink of the first inkjet layer 21 may be, for example, an acrylic-based UV (ultraviolet) curable ink. The ink of the second inkjet layer 22 may be, for example, an acrylic-based UV (ultraviolet) curable ink. The ink of the first inkjet layer 21 and the ink of the second inkjet layer 22 may be composed of the same type of material as each other, or may be composed of different types of materials from each other. The color of the first inkjet layer 21 may be composed of a single white-based color, or may be composed of a plurality of white-based colors (in other words, a white-based pattern) arranged separately from each other.

[0024] If the color of the second inkjet layer 22 is colored, it may be any color. Also, the color of the second inkjet layer 22 may be composed of a single color, or may be composed of a plurality of colors (in other words, a pattern) arranged separately from each other. That is, the second inkjet layer 22 may have a plurality of parts composed of different colors from each other. Here, the color of each of the plurality of parts may be a color different from both the black-based part 11 and the first inkjet layer 21 which is white-based.

[0025] The second inkjet layer 22 may have a first part that is a color different from the black-based part 11 on the base material 10. The whole of the second inkjet layer 22 may be the first part, or a part of the second inkjet layer 22 may be the first part. In this case, it is easy to distinguish between the first part and the part 11 in the second inkjet layer 22.

[0026] In particular, when the color of the first part is a color other than black-based, the contrast with the black-based part 11 becomes vivid, so it is easy to distinguish between the first part in the second inkjet layer 22 and the part 11 on the base material 10.

[0027] The second inkjet layer 22 may have a second portion that is a color different from the first inkjet layer 21 which is white-based. The entire second inkjet layer 22 may be the second portion, or a part of the second inkjet layer 22 may be the second portion. In this case, it is easy to distinguish between the second portion in the second inkjet layer 22 and the first inkjet layer 21.

[0028] In particular, when the color of the second portion is a color other than white-based, the contrast with the first inkjet layer 21 which is white-based becomes vivid, so it is easy to distinguish between the second portion in the second inkjet layer 22 and the first inkjet layer 21.

[0029] When the second inkjet layer 22 has a first portion and a second portion, the first portion and the second portion may be the same color, or the first portion and the second portion may be different colors from each other.

[0030] The first surface 12 of the black-based part 11 may include, for example, a flat region without undulations or with small undulations. In this case, the first inkjet layer 21 is provided on the flat region. All of the first surface 12 may be a flat region, or the first surface 12 may partially have a flat region.

[0031] Here, in the present disclosure, a flat region without undulations or with small undulations means a surface with a maximum height difference of 5 mm or less. The flat region can also be said to be a flat surface. The undulations here are visible undulations, that is, undulations that can be recognized by the naked eye. Therefore, a flat region without undulations is a surface where no visible undulations exist. Also, a flat region with small undulations is a surface where visible undulations exist but the maximum height difference is 5 mm or less. Undulations include curved surfaces.

[0032] Hereinafter, a flat region without undulations may be referred to as a planar region or a plane. Further, a flat region without undulations or with small undulations, on which an inkjet layer is provided, may be referred to as a printing flat region. It can be said that the printing flat region is a region where an inkjet layer is provided and the maximum height difference in that region is 5 mm or less.

[0033] FIG. 2 is a schematic diagram showing an example of an inkjet printing method for performing inkjet printing on a black-colored portion 11. First, a target substrate 10 having a black-colored portion 11 that is black and has a first surface 12 is prepared. Next, as shown in FIG. 2, in step s1, in an inkjet printing apparatus including an inkjet head and a computer, etc., a white first ink layer is inkjet printed on the first surface 12 of the black-colored portion 11 of the substrate 10. As a result, a first inkjet layer 21 is provided on the first surface 12 of the black-colored portion 11. Next, in step s2, a second ink layer is inkjet printed on the first ink layer (that is, the first inkjet layer 21). Thus, a second inkjet layer 22 is laminated on the first inkjet layer 21.

[0034] As described above, in this example, the second inkjet layer 22 (in other words, the second ink layer) is provided on the black-colored portion 11 via the white first inkjet layer 21 (in other words, the first ink layer). On the other hand, when the inkjet layer is directly provided on the black-colored portion, the black color may be seen through from the inkjet layer, and the color development property of the inkjet layer may deteriorate. When the second inkjet layer 22 is provided on the black-colored portion 11 via the white first inkjet layer 21 as in this example, it becomes difficult to see the black color through from the second inkjet layer 22, and the color development property of the second inkjet layer 22 is improved.

[0035] In addition, since the color development property of the second inkjet layer 22 is improved, the damage to the second inkjet layer 22 becomes easier to visually recognize. As a result, the management of the damage degree of the laminated member 1 becomes easy.

[0036] Furthermore, when the first surface 12 of the black portion 11 includes a flat region as in the above example, the inkjet layer 20 is easily formed on the first surface 12 of the black portion 11 .

[0037] The thickness of the first inkjet layer 21 may be 60 μm or more and 120 μm or less. When the thickness is 60 μm or more, the black color of the black portion 11 is less likely to show through the second inkjet layer 22, and the color development of the second inkjet layer 22 is further improved. When the thickness is 120 μm or less, the white color of the first inkjet layer 21 is less likely to show through the second inkjet layer 22, and the color development of the second inkjet layer 22 is further improved. The effect of the thickness is more noticeable when the thickness of the second inkjet layer 22 is 60 μm or more and 120 μm or less.

[0038] Depending on the adhesion of the ink of the first inkjet layer 21 to the surface of the black part 11, the laminate member 1 may include a primer layer 30 located between the first surface 12 of the black part 11 and the first inkjet layer 21. This improves the adhesion of the ink of the first inkjet layer 21. The primer layer 30 is also called a base layer. FIG. 3 is a schematic diagram showing a cross-sectional structure of an example of a laminate member 1 including a primer layer 30. FIG. 3 also shows a clear layer 40, which will be described later. In the example of FIG. 3, the primer layer 30 is located between the first surface 12 of the black part 11 and the first inkjet layer 21.

[0039] The primer layer 30 is colorless and transparent, and may be made of, for example, an acrylic resin, a polyester resin, or a polyamide resin. The primer layer 30 may be formed on the surface of the black portion 11 by inkjet printing or by other methods.

[0040] For example, when the material of the black-colored part 11 is acrylic resin, glass, stainless steel, aluminum, etc., a primer layer 30 may be provided between the black-colored part 11 and the first inkjet layer 21. On the other hand, when the material of the black-colored part 11 is, for example, ABS resin, rigid vinyl chloride, wood, paper, cloth, or leather, etc., the primer layer 30 may not be provided between the black-colored part 11 and the first inkjet layer 21.

[0041] When the laminated member 1 includes the primer layer 30, in the example of FIG. 2 described above, before step s1, the primer layer 30 is formed on the black-colored part 11. Thereafter, in step s1, the first ink (that is, the first inkjet layer 21) is laminated on the primer layer 30.

[0042] As shown in FIG. 3, the laminated member 1 may include a clear layer 40 laminated on the second inkjet layer 22. Thereby, the glossiness of the surface of the laminated member 1 is improved. The clear layer 40 is a colorless and transparent ink layer and may be composed of, for example, an acrylic-based UV curable ink. The clear layer 40 may function as a film for protecting the inkjet layer 20. In this case, the inkjet layer 20 is less likely to deteriorate, and the visibility of the inkjet layer 20 can be maintained for a long time.

[0043] The clear layer 40 may be inkjet printed or formed by other methods. The ink of the clear layer 40 may be composed of the same type of material as the ink of the first inkjet layer 21, or may be composed of a different type of material from the ink of the first inkjet layer 21. Also, the ink of the clear layer 40 may be composed of the same type of material as the ink of the second inkjet layer 22, or may be composed of a different type of material from the ink of the second inkjet layer 22.

[0044] When the laminated member 1 includes the clear layer 40, in the example of FIG. 2 described above, after step s2, the clear layer 40 is laminated on the second ink layer (that is, the second inkjet layer 22).

[0045] In the example of FIG. 3, the laminated member 1 includes both the primer layer 30 and the clear layer 40, but it may include only one of the primer layer 30 and the clear layer 40.

[0046] The laminated member 1 can be used as various members. The laminated member 1 may be used, for example, as an inkjet-printed case (in other words, a housing) provided in a device such as an electric device, an electronic device, or a mechanical device. For example, the laminated member 1 may be used as an inkjet-printed case provided in a battery that outputs electric power. Further, the laminated member 1 may be used as an inkjet-printed case provided in a fan unit that takes in and discharges air. Hereinafter, a case where the laminated member 1 is used as an inkjet-printed case 100 provided with a fan unit 50 that takes in and discharges air will be described.

[0047] FIGS. 4 to 6 are schematic views showing an example of the fan unit 50. FIG. 4 shows an example of the fan unit 50 provided with the inkjet-printed case 100. FIGS. 5 and 6 show an example of the fan unit 50 provided with the case 100 in a state where no inkjet printing has been performed. FIGS. 4 and 5 show an example of how the fan unit 50 is viewed from the intake side in a plan view. Further, FIG. 6 shows an example of how the fan unit 50 is viewed obliquely from the intake side. In FIG. 6, the fan main body 80 and the fixing member 60, which will be described later, provided in the fan unit 50 are shown in a state where they are separated from each other.

[0048] The fan unit 50 is used, for example, in a state of being attached to a member. The fan unit 50 and the member to which the fan unit 50 is attached can be collectively referred to as a fan set. FIG. 7 is a schematic view showing an example of how the fan unit 50 is attached to an article of clothing 900, which is an example of the above-described member. FIG. 7 shows an example of the fan set. FIG. 8 is a schematic view showing only the article of clothing 900.

[0049] In the examples of FIGS. 7 and 8, the garment 900 is a top, and the fan unit 50 is attached to the lower part of the back of the garment 900. The position where the fan unit 50 is attached to the garment 900 is not limited to the example of FIG. 7. Also, in the example of FIG. 7, two fan units 50 are attached to the garment 900, but the number of fan units 50 attached to the garment 900 may be one, or may be three or more.

[0050] As shown in FIG. 8, the garment 900 has attachment holes 910 for attaching the fan unit 50 to the garment 900. The fan unit 50 is attached to the attachment holes 910. As will be described later, the fan unit 50 is attached to the garment 900 so as to sandwich a sheet-like peripheral portion 920 located around the attachment holes 910 in the garment 900. Hereinafter, the garment 900 to which the fan unit 50 is attached may be referred to as a fan-equipped garment 950.

[0051] The fan unit 50 takes in air from one side and discharges the taken-in air from the other side. The fan unit 50 is attached to the garment 900 such that the side where the air is taken in (i.e., the intake side) is on the outside of the garment 900 and the side where the air is discharged (i.e., the exhaust side) is on the inside of the garment 900. In the fan-equipped garment 950, during its rotation, the fan unit 50 takes in air from the outside of the garment 900 into the inside through the attachment holes 910. The air taken into the inside of the garment 900 circulates inside the garment 900 due to the rotation of the fan unit 50 and is discharged outside the garment 900 from the collar of the garment 900 or the like. Thereby, the body of the wearer of the fan-equipped garment 950, that is, the body of the user, is cooled. The attachment holes 910 of the garment 900 serve as the intake ports for the cooling air, and the collar of the garment 900 or the like serves as the exhaust port for the cooling air.

[0052] The fan unit 50 operates based on the power (in other words, the power source) supplied from the battery. The fan unit 50 is electrically connected to the battery by, for example, a cable. The power output from the battery is supplied to the fan unit 50 through the cable. The fan rotates based on the power from the battery. The battery is accommodated in, for example, the pocket of the garment 900.

[0053] Note that the fan unit 50 may be attached to clothing other than the upper garment. For example, the fan may be attached to the trousers. Also, the fan unit 50 may be attached to something other than clothing. For example, the fan unit 50 may be attached to the waist pouch so as to sandwich the seat portion of the waist pouch, or may be attached to the backpack so as to sandwich the seat portion of the backpack. Also, the fan unit 50 may be attached to the cooler bag so as to sandwich the seat portion of the cooler bag.

[0054] <Structural example of the fan unit> As shown in FIGS. 4 to 6, the fan unit 50 includes, for example, a fan body (also referred to as a fan unit body) 80 and a fixing member 60 for fixing the fan body 80 to the garment 900. The fixing member 60 is, for example, detachable from the fan body 80. FIG. 6 shows an example of a state in which the fixing member 60 is removed from the fan body 80.

[0055] The fan body 80 includes a case 100 that has been inkjet printed. Hereinafter, the case 100 that has been inkjet printed may be simply referred to as the printed case 100 or the case 100. Also, the case 100 in a state where inkjet printing has not been performed is referred to as a case base material 101. The case base material 101 corresponds to the base material 10.

[0056] The printed case 100 includes a case base material 101 and an inkjet layer 520 provided on the surface of the case base material 101. The inkjet layer 520 includes a white first inkjet layer 521 provided on the surface of the case base material 101 and a second inkjet layer 522 laminated on the first inkjet layer 521. The printed case 100 corresponds to the laminated member 1, and the case base material 101 corresponds to the target base material 10. Also, the inkjet layer 520, the first inkjet layer 521, and the second inkjet layer 522 respectively correspond to the inkjet layer 20, the first inkjet layer 21, and the second inkjet layer 22. In the example of FIG. 4, a part of the lower first inkjet layer 521 is exposed from the upper second inkjet layer 522. That is, the second inkjet layer 522 is not laminated on a part of the first inkjet layer 521.

[0057] The fan body 80 includes an impeller (also referred to as a fan) 700 housed in the case 100 (case base material 101). In FIGS. 4 and 5, the rotational axis direction of the impeller 700 is along the depth direction of the paper surface. FIGS. 4 and 5 show an example of a plan view of the fan unit 50 from the intake side along the rotational axis direction of the impeller 700.

[0058] The fan body 80 also includes a motor that rotates the impeller 700 and a connector to which a cable extending from the battery is connected. The motor and the connector are housed in the case 100.

[0059] The power output by the battery is supplied to the motor through the cable and the connector. The motor rotates based on the power from the battery. When the motor rotates, the impeller 700 rotates, and thereby the fan unit 50 rotates. When the impeller 700 rotates, the fan unit 50 takes in air from one side and discharges it to the other side. Hereinafter, the side where the fan unit 50 takes in air (that is, the intake side) may be referred to as the front side, and the side where the fan unit 50 discharges air (that is, the exhaust side) may be referred to as the rear side.

[0060] The case base material 101 is made of, for example, a black-colored material. The case base material 101 is made of, for example, a black-colored resin. The case base material 101 may be made of ABS resin or other types of resin. The case base material 101 may be a single molded product or a combination of a plurality of molded products.

[0061] The case base material 101 has a black-colored portion. In this example, the entire area of the case base material 101 is the black-colored portion. The black-colored portion of the case base material 101 (the whole of the case base material 101 in this example) corresponds to the above-described black-colored portion 11. As will be described later, the case base material 101 has a flange portion 120. The flange portion 120 can be said to be included in the black-colored portion of the case base material 101. The black-colored portion of the case base material 101 has a first surface 102 (see FIG. 5) where the inkjet layer 520 is provided. The first surface 102 corresponds to the above-described first surface 12. The inkjet layer 520 is provided on the flange portion 120 included in the black-colored portion of the case base material 101. The cross-sectional structure of the flange portion 120 and the inkjet layer 520 is, for example, as shown in FIG. 1 above.

[0062] The case base material 101 forms a substantially circular shape when viewed from the front or the back. The case base material 101 includes, for example, a front surface portion 110, a rear surface portion (also referred to as a back surface portion) 170, and a cylindrical peripheral wall portion (also referred to as a side wall portion) 180 that connects the front surface portion 110 and the rear surface portion 170 to each other. The outer shape of the front surface portion 110 forms a substantially circular shape when viewed from the front. The outer shape of the rear surface portion 170 forms a substantially circular shape when viewed from the back. The peripheral wall portion 180 forms, for example, a cylindrical shape and connects the peripheries of the front surface portion 110 and the rear surface portion 170.

[0063] The front surface portion 110 has an annular and plate-like flange portion 120 at its peripheral end. Further, the front surface portion 110 has an air intake portion 130 inside the annular flange portion 120 for taking air into the case base material 101. The flange portion 120 surrounds the air intake portion 130. The flange portion 120 protrudes in the radial direction of the front surface portion 110 more than the peripheral wall portion 180. The inkjet layer 520 is provided on the front surface (in other words, the air intake side surface) of the flange portion 120. That is, the first surface 102 of the black-colored portion of the case base material 101 includes the air intake side surface of the flange portion 120.

[0064] The air intake portion 130 includes a plurality of air intake ports 131 and a plurality of ribs 132 that define the plurality of air intake ports 131. Air is taken into the case base material 101 (in other words, inside the case 100) from the plurality of air intake ports 131. The central portion 111 of the front surface portion 110 is a closed region where no air intake port 131 is provided when viewed from the air intake side.

[0065] The plurality of ribs 132 include a plurality of radial ribs 132a that extend radially from the central portion 111 along the radial direction of the front surface portion 110, and a plurality of circular circumferential ribs 132b that extend along the circumferential direction of the front surface portion 110. The plurality of radial ribs 132a extend linearly, for example, from the outer peripheral edge of the central portion 111 to the inner peripheral edge portion of the flange portion 120. The plurality of circumferential ribs 132b are arranged concentrically so as to surround the central portion 111. Each circumferential rib 132b is arranged so as to connect the plurality of radial ribs 132a. Each radial rib 132a extends so as to cross the plurality of circumferential ribs 132b. Note that the shape of the ribs provided in the air intake portion 130 is not limited to this.

[0066] On the outer peripheral surface of the front side portion of the peripheral wall portion 180, a male screw portion 181 that engages with a female screw portion 62 (described later) of the fixing member 60 is formed. The rear side portion, which consists of the rear side portion of the peripheral wall portion 180 and the rear surface portion 170 connected to the rear side portion, constitutes an exhaust portion 190 that discharges the air taken in from the intake portion 130 to the outside of the case 100 (in other words, the case base material 101). The exhaust portion 190 includes a plurality of exhaust ports 191 and a plurality of ribs 192 that define the plurality of exhaust ports 191.

[0067] In the fan unit 50, when the impeller (in other words, the fan) 700 is rotating, air is taken into the case 100 (in other words, the case base material 101) from each intake port 131 of the intake portion 130. Then, the air taken into the case 100 is discharged to the outside of the case 100 from each exhaust port 191 of the exhaust portion 190.

[0068] The fixing member 60 is an annular member for fixing the fan body 80 to the clothing 900. The fixing member 60 includes an annular mounting portion 61 that is attached to the fan body 80. On the inner peripheral surface of the mounting portion 61, a female screw portion 62 that engages with the male screw portion 181 of the peripheral wall portion 180 of the fan body 80 is provided. Further, the fixing member 60 includes a flange portion 65 that protrudes in the radial direction of the fixing member 60 from the outer peripheral surface so as to surround the outer peripheral surface of the mounting portion 61. The flange portion 65 is annular and plate-shaped, and is provided at the front peripheral end portion of the outer peripheral surface of the mounting portion 61.

[0069] When the fan unit 50 having the above structure is attached to the attachment hole 910 of the clothing 900, first, the case 100 of the fan body 80 is inserted into the attachment hole 910 from the outside of the clothing 900. At this time, the case 100 is inserted into the attachment hole 910 from the rear surface portion 170 side. When the case 100 is inserted into the attachment hole 910 from the rear surface portion 170 side, the flange portion 120 of the front surface portion 110 contacts the outer surface of the peripheral portion 920 of the attachment hole 910 of the clothing 900 without passing through the attachment hole 910.

[0070] Next, the fixing member 60 is attached to the case 100 from the inside of the garment 900 such that the flange portion 65 of the fixing member 60 contacts the inner surface of the peripheral portion 920 of the garment 900. Specifically, while the flange portion 65 contacts the inner surface of the peripheral portion 920, the fixing member 60 is attached to the peripheral wall portion 180 such that the female screw portion 62 on the inner peripheral surface of the fixing member 60 is screwed onto the male screw portion 181 on the outer peripheral surface of the peripheral wall portion 180 that protrudes inside the garment 900. Then, by tightening the fixing member 60 clockwise as viewed from the inside of the garment 900, the flange portion 120 of the front portion 110 and the flange portion 65 of the fixing member 60 sandwich the sheet-like peripheral portion 920 of the garment 900. Thereby, the fan unit 50 is fixed to the garment 900. When the impeller 700 of the fan unit 50 fixed to the garment 900 rotates, the air outside the garment 900 is taken into the inside of the garment 900 through the intake port 131 and the exhaust port 191. The air taken into the inside of the garment 900 circulates inside the garment 900 due to the rotation of the fan unit 50 (that is, due to the rotation of the impeller 700) and is discharged outside the garment 900 from the collar of the garment 900 and the like.

[0071] On the other hand, when the fan unit 50 is removed from the garment 900, the fixing member 60 is rotated counterclockwise as viewed from the inside of the garment 900, and the fixing member 60 is removed from the case 100. Then, the case 100 is taken out from the mounting hole 910.

[0072] Note that the method of attaching the fan unit 50 to the garment 900 is not limited to the above example. Also, the fan unit 50 may not be detachable from the garment 900 and may be attached to the garment 900 in a non-detachable manner.

[0073] <Regarding the flange portion of the case base material> Figs. 9 to 11 are schematic views showing an example of the cross-sectional structure of the flange portion 120 of the case base material 101. Fig. 9 shows an example of the cross-sectional structure taken along the line A-A in Fig. 5. Fig. 10 shows an example of the cross-sectional structure taken along the line B-B in Fig. 5. Fig. 11 shows an example of the cross-sectional structure taken along the line C-C in Fig. 5. Fig. 11 shows only the cross-sectional structure of the flange portion 120.

[0074] The plate-shaped flange portion 120 includes an annular intake side surface 200 located on the intake side (in other words, the front side), an annular exhaust side surface 280 located on the exhaust side (in other words, the rear side), and an annular peripheral end surface (also referred to as the peripheral side surface) 290 that connects the intake side surface 200 and the exhaust side surface 280. Each of the intake side surface 200 and the exhaust side surface 280 can be said to be a main surface, for example. The intake side surface 200 faces the front side, the exhaust side surface 280 faces the rear side, and the peripheral end surface 290 faces the radial direction of the annular flange portion 120. Hereinafter, the intake side surface 200 is also referred to as the intake side main surface 200. Also, the exhaust side surface 280 is also referred to as the exhaust side main surface 280.

[0075] The intake side surface 200 has a plurality of convex portions 210 (10 convex portions 210 in the examples of Figs. 4 to 6). The convex portion 210 can also be said to be a convex surface. Each convex portion 210 protrudes toward the front side (in other words, the intake side). The plurality of convex portions 210 are arranged at intervals along the circumferential direction of the flange portion 120. A plurality of some of the plurality of convex portions 210 (5 convex portions 210 in the examples of Figs. 4 to 6) are arranged at equal intervals, and a plurality of some of the plurality of convex portions 210 (5 convex portions 210 in the examples of Figs. 4 to 6) are arranged at equal intervals.

[0076] The peripheral end surface 290 has a plurality of convex portions 291 (16 convex portions 291 in the examples of Figs. 4 to 6). The convex portion 291 can also be said to be a convex surface. Each convex portion 291 protrudes along the radial direction of the annular flange portion 120. The plurality of convex portions 291 are arranged at intervals along the circumferential direction of the flange portion 120. The plurality of convex portions 291 are arranged at equal intervals so as to surround, for example, the intake portion 130. A plurality of some of the plurality of convex portions 291 (10 convex portions 291 in the examples of Figs. 4 to 6) are respectively connected to the plurality of convex portions 210 of the intake side surface 200.

[0077] Thus, since the convex portions are provided on each of the intake side surface 200 and the circumferential end surface 290, when a user grasps the flange portion 120 by hand when, for example, attaching the fan unit 50 to the clothing 900, it is difficult for the hand to slip.

[0078] In addition, the number and arrangement of the convex portions 210 are not limited to the examples in FIGS. 4 to 6. Further, the number and arrangement of the convex portions 291 are not limited to the examples in FIGS. 4 to 6. Further, the intake side surface 200 may not include the convex portion 210. Further, the circumferential end surface 290 may not include the convex portion 291.

[0079] The annular intake side surface 200 is composed of an annular inner peripheral edge portion 250, an annular outer peripheral edge portion 260, and an annular intermediate portion 270 between the inner peripheral edge portion 250 and the outer peripheral edge portion 260. The outer peripheral edge portion 260 of the intake side surface 200 is connected to the circumferential end surface 290. Each radial rib 132a of the intake portion 130 extends from the central portion 111 of the front surface portion 110 to the inner peripheral edge portion 250 of the intake side surface 200.

[0080] Each convex portion 210 of the intake side surface 200 extends from the inner edge (in other words, the inner peripheral side edge) to the outer edge (in other words, the outer peripheral side edge) of the annular intake side surface 200. The inner end portion 215 of the convex portion 210 is included in the inner peripheral edge portion 250 of the intake side surface 200. The outer end portion 216 of the convex portion 210 is included in the outer peripheral edge portion 260 of the intake side surface 200. And the intermediate portion 217 between the inner end portion 215 and the outer end portion 216 in the convex portion 210 is included in the intermediate portion 270 of the intake side surface 200.

[0081] The inner peripheral edge portion 250 is, for example, curved round as a whole and constitutes a curved surface (see FIGS. 9 and 10). Thus, it becomes easier to take in air into the intake portion 130 located inside the inner peripheral edge portion 250. The upper surface 215a of the inner end portion 215 of the convex portion 210 included in the inner peripheral edge portion 250 is a curved surface. Further, the outer peripheral edge portion 260 is, for example, curved round as a whole and constitutes a curved surface (see FIGS. 9 and 10). The upper surface 216a of the outer end portion 216 of the convex portion 210 included in the outer peripheral edge portion 260 is a curved surface.

[0082] Note that the outer peripheral edge portion 260 may extend from the intermediate portion 270 toward the exhaust side surface 280 and be directly connected to the exhaust side main surface 280. That is, in FIGS. 9 and 10, there may be no peripheral end surface 290, and the outer peripheral edge portion 260 may extend while curving from the intermediate portion 270 to the exhaust side main surface 280. In this case, the visibility on the side surface side (the side where the peripheral end surface 290 was located) of the outer peripheral edge portion 260 is improved. Further, the visibility is similarly improved even when the inkjet layer 520 is located on the side surface side of the outer peripheral edge portion 260.

[0083] At least a part of the inner peripheral edge portion 250 may be a flat region instead of a curved surface. Further, the upper surface 215a of the inner end portion 215 of the convex portion 210 may be a flat region. Further, at least a part of the outer peripheral edge portion 260 may be a flat region. Further, the upper surface 216a of the outer end portion 216 of the convex portion 210 may be a flat region.

[0084] In the intermediate portion 270, the region between two convex portions 210 adjacent to each other in the circumferential direction of the flange portion 120 is a flat region 271 without undulations (see FIG. 10). Further, the upper surface 217a of the intermediate portion 217 of the convex portion 210 included in the intermediate portion 270 is a flat region (see FIGS. 9 and 10). The flat region 271 and the upper surface 217a are perpendicular to, for example, the direction along the rotation axis direction of the impeller 700.

[0085] As shown in FIG. 11, the convex portion 210 may have a top portion and a pair of side surfaces 219 extending along the radial direction of the flange portion 120. Each of the pair of side surfaces 219 is inclined inward of the convex portion 210 toward the top portion (in other words, the upper surface side). The pair of side surfaces 219 are included in the intake side main surface 200 of the flange portion 120. In the example of FIG. 11, the side surface 219 is an inclined curved surface, but it may be an inclined plane.

[0086] When the fan unit 50 is viewed from the intake side in a plan view, the entire area of the intake side surface 200 of the flange portion 120 is visible. Specifically, as shown in FIGS. 4 and 5, when the fan unit 50 is viewed from the intake side in a plan view along the rotational axis direction of the impeller 700, the entire area of the intake side surface 200 of the flange portion 120 is visible. When the fan unit 50 is viewed from the intake side in a plan view along the rotational axis direction of the impeller 700, for example, the inner peripheral edge portion 250 and the outer peripheral edge portion 260 of the intake side surface 200 are visible, and the pair of side surfaces 219 of the convex portion 210 are visible.

[0087] In the example of FIG. 4, the entire area of the intake side surface 200 of the flange portion 120 is a printed flat area where the first inkjet layer 521 is provided. The first surface 102 of the black-colored portion of the case base material 101 includes the entire area of the intake side main surface 200 of the flange portion 120. In the example of FIG. 4, the first surface 102 is composed only of the intake side main surface 200.

[0088] The maximum height difference on the intake side surface 200 is 5 mm or less. On the intake side surface 200, for example, the position of the upper surface 217a (in other words, the flat area) of the intermediate portion 217 of the convex portion 210 is the highest. Also, on the intake side surface 200, for example, the position of the outer edge of the outer peripheral edge portion 260 is the lowest. On the intake side surface 200, the height difference d (see FIG. 10) between the outer edge of the outer peripheral edge portion 260 and the upper surface 217a of the intermediate portion 217 of the convex portion 210 is 5 mm or less. The height difference d between the outer edge of the outer peripheral edge portion 260 and the upper surface 217a can also be said to be the distance between the outer edge of the outer peripheral edge portion 260 and the upper surface 217a along the direction perpendicular to the flat area 271. Also, the height difference d between the outer edge of the outer peripheral edge portion 260 and the upper surface 217a can also be said to be the distance between the outer edge of the outer peripheral edge portion 260 and the upper surface 217a along the rotational axis direction of the impeller 700.

[0089] On the intake side surface 200, for example, the height difference between the highest position (in this example, the upper surface 217a of the middle portion 217 of the convex portion 210) and the position of the flat region 271 of the middle portion 270 is 2 mm or less, and the height difference between the lowest position (in this example, the position of the outer edge of the outer peripheral edge portion 260) and the position of the flat region 271 is 2 mm or less. The height difference between the highest position and the position of the flat region 271 can also be said to be the distance between the highest position and the flat region 271 along the direction perpendicular to the flat region 271 or the rotation axis direction of the impeller 700. Also, the height difference between the lowest position and the position of the flat region 271 can also be said to be the distance between the lowest position and the flat region 271 along the direction perpendicular to the flat region 271 or the rotation axis direction of the impeller 700.

[0090] FIG. 12 is a schematic view showing an example of the inkjet layer 520 provided on the intake side surface 200. The first inkjet layer 521 is provided over the entire area of the intake side surface 200. The second inkjet layer 522 is provided on a part of the first inkjet layer 521. As a result, a part of the lower first inkjet layer 521 is exposed from the upper second inkjet layer 522.

[0091] The exposed portion 521a of the first inkjet layer 521 represents, for example, characters. In the examples of FIGS. 4 and 12, the exposed portions 521a are provided at two locations (the upper and lower two locations in FIGS. 4 and 12). The two exposed portions 521a represent, for example, the same characters as each other. The exposed portion 521a represents, for example, the string "FAN" in a white color system. The exposed portion 521a is located, for example, on the flat region 271 of the intake side surface 200.

[0092] Note that the characters represented by the exposed portion 521a are not limited to this. Also, the two exposed portions 521a may represent different characters from each other. Also, the exposed portion 521a may be provided at three or more locations. Also, the exposed portion 521a may represent, for example, a pattern other than characters.

[0093] In the examples of FIGS. 4 and 12, the second inkjet layer 522 has, for example, a plurality of colors. For example, the second inkjet layer 522 has three colors arranged separately from each other. The second inkjet layer 522 includes a first portion 522a having a first color, a second portion 522b having a second color different from the first color, and a third portion 522c having a third color different from the first color and the second color.

[0094] In the second inkjet layer 522, it can be seen that the first color of the first portion 522a serves as the base color, and the second color of the second portion 522b and the third color of the third portion 522c are attached as patterns to the base first color. The second portion 522b represents, for example, a large circle pattern, and the third portion 522c represents, for example, a small circle pattern.

[0095] The first color, the second color, and the third color may include colors other than black-based colors, may include colors other than white-based colors, or may include colors other than black-based and white-based colors. Also, the first color, the second color, and the third color may include at least one of black-based and white-based colors. Further, when the color of the first inkjet layer 521 is composed of a single color, the first color, the second color, and the third color may include the same color as the single color, or may include a color different from the single color. Also, when the color of the first inkjet layer 521 is composed of a plurality of colors, the first color, the second color, and the third color may include the same color as at least one of the plurality of colors, or may include a color different from at least one of the plurality of colors.

[0096] In this example, as shown in FIGS. 12 and 11, the edge (specifically, the inner edge) of the inkjet layer 520 has a recess 525 located at the connection portion between the intake side surface 200 and the radial rib 132a. The recess 525 is provided at the inner edge of the first inkjet layer 521 and the second inkjet layer 522.

[0097] In this example, by checking the position of the recess 525, the printing misalignment of the inkjet layer 520 can be identified. For example, when the printing of the inkjet layer 520 is misaligned in the circumferential direction of the annular flange portion 120, the position of the recess 525 will be shifted from the connection portion between the intake side surface 200 and the radial rib 132a. By checking that the position of the recess 525 is shifted from the connection portion between the intake side surface 200 and the radial rib 132a, the printing misalignment of the inkjet layer 520 can be identified. Thereby, the possibility that the fan unit 50 in which the printing misalignment of the inkjet layer 520 has occurred flows into the market is reduced.

[0098] In addition, the inkjet layer 520 may be provided on the surface of the end portion on the flange portion 120 side in at least one of the plurality of radial ribs 132a. In this case, a recess 525 may or may not be formed on the inner edge of the inkjet layer 520. In this case, the printed flat area of the case 100 includes the area of the surface of the radial rib 132a where the inkjet layer 520 is provided.

[0099] The second inkjet layer 522 may be provided in the entire area of the first inkjet layer 521. In this case, the second inkjet layer 522 may have a white portion representing the character "FAN" at the same location as the location where the character "FAN" is shown in the example of FIG. 12. Also, the patterns represented by the second portion 522b and the third portion 522c of the second inkjet layer 522 are not limited to the above example. Also, at least one of the second portion 522b and the third portion 522c may represent at least one character. Also, the number of colors of the second inkjet layer 522 may be two, four or more, or one.

[0100] Also, similar to the example of FIG. 3 described above, the case 100 of the fan unit 50 may include a primer layer 30 located between the intake side surface 200 of the flange portion 120 and the first inkjet layer 521. Further, the case 100 of the fan unit 50 may include a clear layer 40 laminated on the second inkjet layer 522.

[0101] As described above, in the case 100 of the fan unit 50 in this example, the intake side surface 200, which is a printed plane area, includes a curved surface. That is, the inkjet layer 520 is provided on the curved surface included in the intake side surface 200 of the flange portion 120. Thereby, the glossiness of the intake side surface of the case 100 is improved, and as a result, the design property of the case 100 is improved.

[0102] Also, as in the example of FIG. 4 etc., when the inkjet layer 520 is provided on the curved surface included in the inner peripheral edge portion 250 of the intake side surface 200, the glossiness of the inner peripheral edge portion 250 is improved.

[0103] Also, as in the example of FIG. 4 etc., when the inkjet layer 520 is provided on the curved surface included in the outer peripheral edge portion 260 of the intake side surface 200, the glossiness of the outer peripheral edge portion 260 is improved.

[0104] Also, in the example of FIG. 11, the circumferential side surface 219 of the flange portion 120 at the convex portion 210 of the intake side surface 200 is inclined inward of the convex portion 210 toward the top side of the convex portion 210. By providing the inkjet layer 520 on such a side surface 219, the glossiness of the intake side surface of the case 100 is improved.

[0105] Note that at least one of the pair of side surfaces 219 may be a surface perpendicular to the plane area 271. Also, at least one of the pair of side surfaces 219 may be inclined outward of the convex portion 210 toward the top side of the convex portion 210, contrary to the example of FIG. 11.

[0106] The inkjet layer 520 may not be provided on a part of the intake side surface 200. In other words, the inkjet layer 520 may be provided only on a part of the intake side surface 200. Further in other words, a part of the intake side surface 200 may not be included in the printed flat region. Further in other words, the first surface 102 of the black-colored portion of the case base material 101 may not include a part of the intake side surface 200.

[0107] For example, the inkjet layer 520 may not be provided on at least a part of the inner peripheral edge portion 250 of the intake side surface 200. Also, the inkjet layer 520 may not be provided on at least a part of the outer peripheral edge portion 260 of the intake side surface 200. Also, the inkjet layer 520 may not be provided on at least a part of the middle portion 270 of the intake side surface 200. Also, the inkjet layer 520 may not be provided on at least a part of the upper surface of the convex portion 210 of the intake side surface 200. Also, the inkjet layer 520 may not be provided on one of the pair of side surfaces 219 of the convex portion 210. Also, the inkjet layer 520 may not be provided on at least a part of the side surface 219. That is, the first surface 102 of the black-colored portion of the case base material 101 may include at least a part of the pair of side surfaces 219.

[0108] Also, the inkjet layer 520 may be provided not only on the intake side main surface 200 but also on other surfaces of the case base material 101. That is, the first surface 102 of the black-colored portion of the case base material 101 may include a region other than the intake side main surface 200. For example, the inkjet layer 520 may be provided on the inner surface of the peripheral wall portion 180 of the case base material 101. In this case, the inkjet layer 520 may be provided continuously with the intake side main surface 200 in a region that is visible simultaneously with the intake side main surface 200 when the fan unit 50 is viewed from the intake side in a plan view among the inner surfaces of the peripheral wall portion 180. Thereby, the inkjet layer 520 is provided from the intake side main surface 200 to the inner surface of the peripheral wall portion 180.

[0109] Also, a white first inkjet layer and a second inkjet layer may be laminated on the surface of the case provided with the battery that outputs power to the fan unit 50.
