[0026] A one-to-one production method is effective for improving customer satisfaction in terms of reflecting the user's intention (demand) compared to a standardized mass production method. In the case of implementing a one-to-one production method with respect to a sheet to be attached to the skin for use, it is desirable to provide the above-described sheet in an appropriate shape and size corresponding to the part of the body to which it is to be attached and the size of the part. However, Patent Literature 1 does not disclose a technique that takes into account a one-to-one production method. Patent Literature 2 does not disclose a technique for providing the above-described sheet in an appropriate shape and size.

[0027] Therefore, the present application relates to a sheet providing method and a sheet providing system that can eliminate the disadvantages of the prior art.

[0028] Hereinafter, the present application will be described based on preferred embodiments with reference to the accompanying drawings. In the present specification, the "sheet providing method" is a method of providing a sheet to a user who is a sheet purchaser, taking into account the above-described one-to-one production method. The above-described sheet can be attached to a body surface such as the skin for use. The part of the body to which the sheet is to be attached is not particularly limited, and as the part, for example, the face such as the forehead, the nose, the eye, the cheek, the ear, and the like; the hand such as the finger, the palm, the back of the hand, and the like; the upper arm; the elbow; the lower arm; the foot such as the toe, the sole, and the like; the thigh; the back; the chest; the shoulder; the neck; the head; the hip; and the like can be cited. The above-described sheet can be attached to a plurality of adjacent parts on the body.

[0029] The sheet providing method of the present application is suitable for various cosmetic methods that are not intended for a surgical, therapeutic, or diagnostic method of the human body. Figure 1 An embodiment of the sheet of the present application is shown. The sheet 10 of the present embodiment is used for the purpose of improving the appearance and state of the body surface by being attached to the body surface of each user. For example, the sheet 10 can be used for the purpose of whitening the skin of the application site, concealing the color spots of the skin, concealing the darkening / dark circles of the skin, concealing the wrinkles of the skin, concealing the skin blush, protecting the skin from ultraviolet rays, and moisturizing the skin. In addition to this, the sheet 10 can be used for various behaviors for protecting the skin performed by the individual at home, such as protection of various wounds such as abrasions, cuts, lacerations, and puncture wounds, prevention of pressure ulcers, and the like.

[0030] ​The plan view shape of the sheet 10 of the present embodiment is not particularly limited, and can be any plan view shape according to the user's needs. For example, the plan view shape of the sheet 10 can be a polygonal shape such as a triangle, a quadrangle, a hexagon, a circular shape, an elliptical shape, or the like. In addition, the plan view shape of the sheet can be a shape having a contour including a plurality of curved portions having different curvatures, or a shape having a contour including a straight portion and a curved portion, as shown in Figure 1 .

[0031] From the viewpoint of more appropriately attaching the sheet 10 to a part of the body, the sheet 10 preferably has a shape corresponding to the part of the body to be attached. For example, in the case of attaching the sheet 10 to the eye area, the contour of the sheet 10 preferably has a curved portion that curves along the edge of the eye (see Figure 1 ). For example, in the case of attaching the sheet 10 to the entire face, the sheet 10 preferably has substantially the same contour as the face, and has an opening portion at a position corresponding to the eye, the nostril, and the mouth.

[0032] The sheet 10 of the present embodiment includes the base material layer 12 and the sheet layer 11 attached to the skin. The sheet layer 11 of the present embodiment is formed using a high molecular compound capable of forming a film as a raw material, by discharging the liquid raw material from a discharge nozzle described later. That is, it is formed by discharging the liquid raw material onto one face of the base material layer 12. The sheet layer 11 is very thin, but is depicted as being very large in Figure 2 for the sake of convenience in explanation.

[0033] The sheet layer 11 can have a certain thickness, or can have different thicknesses depending on the position, as shown in Figure 2 . The sheet layer 11 of the present embodiment, as shown in Figure 2 , has a thickness that gradually increases from the peripheral edge end 17 toward the inside, and the surface of the sheet layer 11 is inclined in a cross section along the thickness direction Z of the sheet 10.

[0034] From the viewpoint of further improving the effect of improving the appearance and state of the body surface, that is, from the viewpoint of easily hiding wrinkles, discolorations, and the like of the application site, the maximum thickness tl of the sheet layer 11 (see Figure 2 ) is preferably 5.1 μm or more, and more preferably 10 μm or more.

[0035] In addition, from the viewpoint of making the appearance of the sheet unobtrusive when attached to the skin, the maximum thickness tl of the sheet layer 11 is preferably 500 μm or less, and more preferably 400 μm or less.

[0036] In this embodiment, the thickness of the sheet layer 11 at its peripheral end 17 is preferably less than the thickness of the portion located on its inner side, and preferably the peripheral end 17 has the smallest thickness when viewed in cross-section. The aforementioned cross-section can be observed, for example, by obtaining a cross-sectional profile curve of the three-dimensional shape described later.

[0037] From the perspective of easily maintaining the sheet condition, the thickness t2 of the peripheral end 17 (refer to...) Figure 2 Preferably, the micrometer size is 0.3 μm or more, and more preferably 0.5 μm or more.

[0038] Furthermore, from the viewpoint of making the interface between the skin and the sheet difficult to see, the thickness t2 of the peripheral end 17 is 10 μm or less, preferably 9 μm or less, and more preferably 8 μm or less.

[0039] (Methods for measuring the three-dimensional shape of sheet layers)

[0040] The thickness t1 of the sheet layer 11 and the thickness t2 of its peripheral end 17 can be obtained by measuring the three-dimensional shape of the sheet layer surface using a laser-type three-dimensional shape measurement system (a combination of the EMS2002AD-3D measurement system manufactured by COMS Co., Ltd. and the LK-2000 displacement sensor manufactured by KEYENCE CORPORATION). First, the sheet 10 is positioned by placing the substrate layer on an automated stage. Then, the automated stage is moved in the X-axis direction while the laser displacement meter scans at a specified measurement interval X. P Measure the surface height of the sheet layer. Then, position the automatic stage along the Y-axis, which is orthogonal to the X-axis, at a measurement interval Y. P The offset causes the automatic stage to move in the X-axis direction, while simultaneously causing the laser displacement meter to scan at a specified measurement interval X. P The surface height of the sheet layer is measured, and the surface shape data of the sheet layer is obtained by repeatedly performing the above actions. The measurement interval along the X-axis is then calculated. P Set to 0.235mm, and set the measurement interval Y along the Y-axis. P The resolution in the height (Z-axis) direction is set to 0.1 μm, with a resolution of 0.350 mm. Furthermore, the measurement range, when viewed from above, encompasses the entire sheet layer in both the X and Y axes; the measurement spacing can be appropriately adjusted according to the object. The above measurements are performed under no-load conditions. Then, based on the measured three-dimensional shape data, the thickness of the sheet layer and the thickness at its peripheral edges are measured. The sheet layer thickness is the maximum thickness based on the three-dimensional shape data. Unless otherwise stated, in the following description, "thickness" refers to the value measured based on the three-dimensional shape data. The thickness at the peripheral edges of the sheet layer 11 based on the three-dimensional shape data can be measured using the following method.

[0041] (Measurement method of thickness of peripheral edge)

[0042] First, a planar profile line indicating the profile shape of the sheet layer in plan view is obtained. The planar profile line can be obtained based on the three-dimensional shape data described above, or can be obtained by magnifying and observing the sheet layer using a microscope or the like. For example, in the case where the sheet layer is composed of nanofibers, there are generally fibers protruding from the surface, and portions where fibers are locally sparse or portions where fibers are locally dense are formed. In this case, the graph in which the measured values of thickness or the like obtained based on the three-dimensional shape data are plotted for each position, specifically, the planar profile line, sometimes contains noise. From the viewpoint of removing the noise, it is preferable to perform an approximate curve processing on the planar profile line using a polynomial approximation formula. In the case where a plurality of approximate curves are obtained by this processing, the approximate curve closest to the three-dimensional shape data is selected. Next, the planar profile curve after the approximate curve processing of the planar profile line is made to correspond to the three-dimensional shape data, the peripheral edge of the sheet layer in the three-dimensional shape data is determined, and the thickness of the peripheral edge is measured.

[0043] The sheet layer 11 of the present embodiment has a region (hereinafter also referred to as "tapered region") in which the thickness of the sheet layer 11 gradually increases from the peripheral edge 17 toward the inside. This tapered region can be determined by obtaining a profile line of a cross section of the sheet layer 11 based on the three-dimensional shape data in the following manner.

[0044] First, in the three-dimensional shape data described above, the position of the largest thickness is determined as the apex position, and the thickness of the sheet layer at the apex position is obtained. Next, based on the three-dimensional shape data described above, an isohypse (hereinafter also referred to as "80% thickness isohypse") indicating the profile of a region where the thickness is 80% of the thickness at the apex position is obtained, and the position of this isohypse is reflected in the three-dimensional shape data together with the planar profile curve. For example, as shown in FIG. 8, the three-dimensional shape data is made to reflect the planar profile curve CO and the 80% thickness isohypse C80. This 80% thickness isohypse is preferably one that has been subjected to the approximate curve processing described above. Next, an arbitrary position on the planar profile curve is set as a first point, and first to tenth points dividing the circumference of the planar profile curve into ten equal parts are set on the planar profile curve. Figure 12 Figure 12 ​The symbols N1 to N10 shown are an example of the first to tenth points. Next, the cross-sectional profile line of the sheet layer in the above-described three-dimensional shape data is obtained at each of the first to tenth points. The cross-sectional profile line is a profile line of a section when the sheet layer of the above-described three-dimensional shape data is cut along a line segment connecting each of the first to tenth points on the planar profile curve with the above-described 80% contour line in the shortest distance in plan view. As described above, from the viewpoint of removing noise, it is preferable to perform the above-described approximate curve processing on the cross-sectional profile line of each of the first to tenth points. Each of the cross-sectional profile curves obtained is caused to reflect the position of the first to tenth points corresponding thereto, and the position of the peripheral edge end of the sheet layer on the cross-sectional profile curve is determined. Next, in each of the cross-sectional profile curves obtained, a slant region in which the thickness gradually increases from the peripheral edge end toward the inside of the sheet layer is determined. The slant region is, for example, a region from the peripheral edge end to the apex position in the cross-sectional profile curve. In addition, as a pattern in which the thickness gradually increases in the cross-sectional profile curve, for example, a pattern in which it increases linearly, a pattern in which it increases curvilinearly such as an S-shaped curve or an exponential function curve, a pattern in which it increases in a plurality of stages, and the like can be cited. Furthermore, the number of points in which the cross-sectional profile curve having the above-described slant region is confirmed among the first to tenth points is measured. When the number of points of the cross-sectional profile curve having the slant region measured is set as "n", the proportion (%) of the number of cross-sectional profile curves having the slant region with respect to the total of 10 sites of the first to tenth points can be obtained by "(n / 10) x 100 (%)". That is, it is possible to determine the percentage of the conical region with respect to the entire length of the peripheral edge of the sheet layer. For example, in a case where the cross-sectional profile curve having the above-described slant region is confirmed at 5 sites among the first to tenth points, it is possible to determine that the sheet layer of the measurement object is a conical region having 50% with respect to the entire length of the peripheral edge of the sheet layer.

[0045] From the viewpoint of further improving the effect of improving the appearance and state of the body surface, the region in which the thickness gradually increases from the peripheral edge end 17 of the sheet layer 11 toward the inside (conical region) with respect to the entire length of the peripheral edge of the sheet layer 11 is preferably 60% or more and 100% or less, more preferably 80% or more, and further preferably 90% or more, and particularly preferably 100%. From the same viewpoint as described above, it is preferable that the conical region exist over the entire length of the peripheral edge of the sheet layer 11.

[0046] The thickness tl of the sheet layer 11 and the thickness t2 of the peripheral edge end 17 of the sheet layer 11 can be measured by using a contact type film thickness meter (LITEMATIC VL-50A (R5mm super hard spherical surface measuring piece) manufactured by Mitutoyo Corporation). The load applied to the measurement object at the time of measurement is 0.01 Pa.

[0047] Next, the method of providing the sheet 10 will be described based on a preferred embodiment with reference to the drawings. Figure 3 A conceptual diagram showing the method of providing the sheet according to the present embodiment is shown in FIG. 1. The method of providing the sheet according to the present embodiment is a method of providing a sheet to a user via a mail-order type distribution route in which a product is purchased through an EC (Electronic Commerce) site or the like, or a face-to-face type distribution route in which a product is purchased through face-to-face sales at a retail store or the like.

[0048] The method of providing the sheet according to the present embodiment can be implemented using the system 100 as one embodiment of the system for providing a sheet according to the present embodiment. Hereinafter, the system for providing a sheet 100 will also be referred to simply as "system 100". Figure 3 An outline of the system 100 is shown in FIG. 2. The system 100 includes a sheet specification determining section 200 for performing a determining step (A), and a sheet forming section 300 for performing a forming step (B).

[0049] The method of providing the sheet according to the present embodiment includes a determining step (A) of determining the shape and size of the sheet 10 for each user based on information about the surface of the body of each user, and a forming step (B) of controlling a discharge nozzle for discharging a raw material of the sheet 10 based on information of the shape and the size, to form the sheet.

[0050] In the method of providing according to the present embodiment, the "information about the surface of the body" is information about the skin of the part of the body to which the sheet 10 is to be attached, and includes information selected from one or more of the part of the body, the color of the skin of the part, the unevenness, the moisture retention, and the elasticity of the skin, and preferably includes the information of the part of the body. The information of the elasticity of the skin refers to information of the viscoelasticity of the skin.

[0051] As the information of the part of the body, there can be mentioned a measured value showing the surface shape of the part to which the sheet is to be attached such as the face, the eye, and the like, the size of the part, an image of the part, the viscoelasticity of the skin, and the like.

[0052] The color information of the skin is information about the lightness and hue of the skin. The color information includes information of the lightness and hue of the skin itself, and information of the color difference between a portion in which a pigment deposit such as a color spot, a darkening, or the like is generated and a portion in which the pigment deposit is not generated, that is, color information of a discoloration portion of the skin. The discoloration portion includes pores, moles, and comedones. As the color information, there can be mentioned a measured value showing the lightness and hue of an L*a*b* color system or the like, an image of the part to which the sheet is to be attached, a spectral characteristic of the skin, and the like.

[0053] The above-mentioned information on the skin surface is information on the concave-convex of the skin surface such as wrinkles, pores, wounds, and the like. As the information on the concave-convex, there can be mentioned a measurement value indicating the depth of a concave portion, the height of a convex portion, an image indicating the size of a concave portion and a convex portion, an image indicating the elastic structure of the skin, and the like.

[0054] As the above-mentioned information on the moisture of the skin, there can be mentioned a measurement value of the moisture amount of the skin, the amount of trans-epidermal water loss, and the like. The moisture amount of the skin can be measured by a known measuring device (for example, manufactured by Courage + Khazaka, model number CM825MP).

[0055] The above-mentioned skin viscoelasticity of the skin can be measured by a known measuring device (for example, manufactured by Courage + Khazaka, model number: MPA580 Dual).

[0056] The above-mentioned brightness, hue, and curvature of the concave-convex can also be calculated based on the pixels of the image data of the skin by a known image processing.

[0057] As described below, from the viewpoint that the calculation process of the kind, shape, and size of the sheet 10 is easily performed, the above-mentioned "information on the body surface" is preferably data that can be processed by a processor such as a central processing unit (CPU). For example, it is preferable that the information (data) that the sheet providing system 100 can process. From the same viewpoint as described above, the above-mentioned "information on the body surface" is preferably image data including the part to which the sheet is to be attached, the image data including the part to which the sheet is to be attached, the color of the skin of the part, and information on the concave-convex.

[0058] In the providing method of the present embodiment, a sheet to be attached to the face is provided to the user for the purpose of beauty, such as skin care, makeup, and the like. The above-mentioned determination step (A) of the present embodiment includes an information acquisition step (Al) of acquiring information on the body surface of each user, and a shape and size determination step (A2) of determining the shape and size of the sheet 10 of each user based on the information.

[0059] In the information acquisition step (Al) of the present embodiment, the information terminal P or a device Q capable of acquiring information on the body surface (hereinafter also referred to as "body surface information acquisition device Q") is used to acquire information on the face surface for each user.

[0060] The information terminal P is a general-purpose computer, a mobile terminal, a tablet terminal, a smart phone, a wearable terminal, or the like.

[0061] The body surface information acquisition device Q is an information terminal capable of inputting information about a body surface, a device capable of measuring or observing the state of skin, or the like. The device capable of measuring or observing the state of skin can measure or observe the moisture amount of the skin, the texture, color, elasticity, and the like of the skin based on an enlarged image of the skin, and can cite, for example, Beauty Power Scope, Beauty Com, and the like manufactured by Kowa Co., Ltd.

[0062] The information terminal P and the body surface information acquisition device Q each include a CPU, a ROM (Read Only Memory), a RAM (Random Access Memory), a flash memory, a camera, a display portion, an input device for a user to perform an input operation, and the like. The CPU can also include a graphics processor (GPU) for image display, a multimedia processor that performs encoding and decoding of High-Definition (HD) video and the like, a display controller that controls a display, a power management integrated circuit (IC) for controlling power supply and charging, and the like. The display portion possessed by the information terminal P and the body surface information acquisition device Q can also use a touch panel or the like that has both display and operation functions. As the input device, a touch panel, a keyboard, a key pad, a touch pad, a mouse, a microphone, and the like can be cited. The user U performs an operation of the information terminal P or the body surface information acquisition device Q using the input device. The processing (for example, image processing) performed by the information terminal P and the body surface information acquisition device Q is realized by the CPU expanding and executing a program stored in the ROM or a disk or the like in the RAM. The above processing can be realized by an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array), or can be realized by a combination of an ASIC and an FPGA.

[0063] In addition, the body surface information acquisition device Q includes a measurement device for acquiring color information, unevenness information, moisture information, and elasticity information of the skin. As the measurement device, a color difference meter or the above various measuring instruments can also be included. Further, the body surface information acquisition device Q can also measure the above brightness, hue, and curvature of unevenness based on image data of the skin acquired by a camera or a microscope. In a case where this measurement is performed, the body surface information acquisition device Q is installed with a program for performing various image processing such as gradation, binarization, RGB division, and HSV conversion on the image data of the skin.

[0064] The information on the body surface acquired in the information acquisition step (Al) is acquired using a camera, a microscope, or a measuring device possessed by the information terminal P or the body surface information acquisition device Q. The information terminal P or the body surface information acquisition device Q can be operated by a user who is to attach the sheet, or can be operated by a person other than the user. In this operation, the input device, the camera, the microscope, or the measuring device described above is used. For example, in a mail-order type distribution route, image data of the user's U own face photographed by the information terminal P held by the user U is acquired as the information on the body surface. Also, in a face-to-face type distribution route, a result obtained by measuring or observing the state of the user's skin using the body surface information acquisition device Q is acquired as the information on the body surface. For example, in the case of using a camera or a microscope, an image of the user's U skin is acquired as the information on the body surface. Also, in the case of using a measuring device, a measured value on the state of the user's U skin measured by a detector such as a sensor possessed by the measuring device is acquired as the information on the body surface. The camera, the microscope, or the measuring device possessed by the body surface information acquisition device Q can also be operated by a salesperson who is a person other than the user.

[0065] In the shape and size determination step (A2) of the present embodiment, based on the information on the body surface of the user U acquired in the information acquisition step (Al), the shape and size of the sheet 10 suitable for the user U are determined. Specifically, the shape and size determination step (A2) includes a shape selection step (A2-1) of letting the user select the shape of the sheet, a position and size determination step (A2-2) of letting the user determine the attachment position of the sheet and the size of the sheet, and a determination processing step (A2-3) of determining the shape and size of the sheet suitable for the user based on the information on the body surface, the kind of the sheet, and the information on the attachment position and the size determined by the user U. With respect to these steps (A2-1) to (A2-3), an example in which the information on the body surface is acquired using the information terminal P including a camera and a touch panel function is described with reference to Figure 4 and Figure 5 In this shape selection step (A2-1) to (A2-3), the kind of the sheet desired by the user U, the attachment position of the sheet, and the size of the sheet are determined (selected). At this time, the user U operates the information terminal P while referring to the image data of the own face acquired by the camera of the information terminal P. The information terminal P transmits information on the attachment position of the sheet and the size of the sheet based on this operation information to the sheet specification determination section 200 possessed by the system 100 via the network (N). The sheet specification determination section 200 of the system 100 described later is a cloud server.

[0066] A network refers to the entire information communication network that utilizes electrical communication technology. In addition to wireless or wired LANs (Local Area Networks) and the Internet, it also includes telephone communication line networks, fiber optic communication networks, cable communication networks, and satellite communication networks.

[0067] In the shape selection step (A2-1), the sheet size determination unit 200 uses the image data of the user U's face to display a selection operation screen allowing the user U to select the type of sheet, and then allows the user U to select the type of sheet. Thus, the user U selects the shape of the sheet. For example, such as... Figure 4 As shown in (a), the sheet material specification determination unit 200 displays a selection operation screen on the display unit of the information terminal P. In the shape selection step (A2-1), information indicating the function and properties of the sheet material may also be provided to the user U along with the (type) shape of the sheet material, allowing the user U to select the shape of the sheet material. The information indicating the function and properties of the sheet material is as follows: Figure 4 The descriptions in (a) include "moisturizing mask," "spot-concealing patch," and "wrinkle-concealing sheet." User U selects a sheet with the desired shape from a variety of sheets displayed on the selection screen. Alternatively, user U may be consulted beforehand via information terminal P about the sheet's purpose and skin concerns. The selection screen may then display one or more candidate sheets selected based on the consultation results, allowing user U to choose from these candidate sheets. The consultation is conducted in the form of a beauty questionnaire, and candidate sheets are appropriately selected based on the answers. In this embodiment, the display of multiple sheet options, the consultation, and the selection of candidate sheets based on the consultation results are performed by the sheet specification determination unit 200.

[0068] In the position and size determination step (A2-2), for the sheet selected by user U in the shape selection step (A2-1), an adjustment operation screen is displayed to allow user U to determine the attachment position and size of the sheet. For example, as Figure 4 As shown in (b), the sheet specification determination unit 200 causes the display unit of the information terminal P to display an adjustment operation screen. Figure 4 (b) indicates the initial state of the adjustment operation screen. User U positions the sheet 10a at the desired location of the face on the adjustment operation screen, determining the attachment position of the sheet 10a. Specifically, as... Figure 5 As shown in (a), user U selects sheet 10a on the adjustment screen and drags it to the desired position on the face to determine the attachment position of sheet 10a. Next, in order to determine the appropriate size of sheet 10a at the determined attachment position, sheet size determination unit 200 allows user U to determine the desired size of the sheet. Specifically, as... Figure 5As shown in (b), the user U pulls the sheet toward or away from the attached position to perform the reduction or enlargement of the sheet 10a, thereby determining the desired size of the sheet 10a. The sheet specification determining section 200 determines the size of the sheet 10a with respect to the Figure 5 As shown in (a) and (b), the user U is prompted with a message or the like for determining the attached position and size of the sheet in the image on the display section of the information terminal P.

[0069] In the shape selection step (A2-1) and the position and size determination step (A2-2), the operations performed by the user U can also be performed by a person other than the user U, such as a salesperson who faces the user U. In this case, the other person performs the selection operation of the sheet, the adjustment operation of the attached position and size of the sheet in accordance with the intention of the user U. In the case where the above-mentioned consultation is performed, the other person performs the operation required for the consultation.

[0070] The information of the shape of the sheet determined by the user U in the shape selection step (A2-1) and the position and size of the sheet in the image determined in the position and size determination step (A2-2) is transmitted to the sheet specification determining section 200 via the network. The sheet specification determining section 200 collects these information from a plurality of users each via the information terminal P or the body surface information acquisition device Q, and stores in the storage section described later.

[0071] In the determination processing step (A2-3), the sheet specification determining section 200 calculates the shape and size of the sheet suitable for the user on the basis of the information of the kind of the sheet determined by the user U in the shape selection step (A2-1), the attached position and size of the sheet, and the information about the face surface, and determines the shape and size. Specifically, the sheet specification determining section 200 derives the size of the sheet on the basis of the image data of the user U, or infers the size (actual size) of the face of the user U, and further derives the size of the sheet corresponding to the attached position and size of the sheet determined by the user U on the basis of the size of the face. The processing method for performing the derivation is performed by the sheet size calculation section 245 described later. The information of the derived size of the sheet is transmitted from the sheet specification determining section 200 to the sheet forming section 300.

[0072] The providing method of the present embodiment includes a step of optimizing the shape and size of the sheet in the determination processing step (A2-3) by machine learning using the learning data stored in the sheet specification determining section 200. The processing of the machine learning in this step is performed by the information utilization section 26 described later. The machine learning will be described in detail in the description of the information utilization section 26.

[0073] In the forming step (B), based on the information on the shape and size of the sheet determined in the determining process step (A2-3), the sheet forming section 300 possessed by the system 100 controls the discharge nozzle for discharging the raw material of the sheet 10 to form the sheet. The sheet forming section 300 includes the sheet layer forming device 40, the cutting device 50, and the processing device 60 (refer to Figure 3 ). These sheet layer forming device 40, cutting device 50, and processing device 60 are all controlled by the manufacturing control section 35 possessed by the sheet forming section 300. As for the manufacturing control section 35, a detailed explanation will be given in the explanation of the system 100 to be described later.

[0074] The sheet layer forming device 40 includes a discharge nozzle 41 discharging the raw material, and discharges the raw material from the discharge nozzle 41 to the continuous sheet 12a of the base material layer to form the sheet layer 11. The discharge nozzle 41 is controlled based on the information on the shape and size of the sheet. This "control" is to control one or two or more conditions selected from the discharge amount of the raw material, the discharge position of the raw material, and the moving track of the discharge nozzle 41 to be described later, in a manner to become the shape and size of the sheet determined in the determining process step (A2-3). As the sheet layer forming device 40, for example, the manufacturing device described in Japanese Patent Application Publication No. 2020-090769, Japanese Patent Application Publication No. 2020-045591 can be used.

[0075] The cutting device 50 cuts the continuous sheet 12a of the base material layer along the contour (peripheral edge end 17) of the sheet layer 11 formed by the sheet layer forming device 40, or at a position where the contour of the sheet layer 11 is deviated to the outer side of the sheet. As the cutting device 50, a cutting device including a cutting head having a laser cutter or a cutter, a slide holding the cutting head, and an XY track stage allowing the slide to move in a planar direction can be used.

[0076] The processing device 60 takes out the sheet 10 obtained by the cutting of the cutting device 50. As the processing device 60, an operator having a robot at the front end of an arm can be used.

[0077] In the case where the sheet is provided via a mail-order type distribution route, the manufacturing of the sheet in the forming step (B) can be performed at a place where a sheet manufacturing business is conducted. The manufactured sheet 10 is given the identification information of the user U, and is packaged into a package or the like. The package or the like is given the information on the delivery destination of the user U, and is then delivered to the user U. Thereby, the sheet 10 is provided to the user U.

[0078] In the case where the sheet is provided via the face-to-face type distribution route, the manufacturing of the sheet in the forming step (B) can also be performed at a place where a sheet manufacturing business is conducted. In this case, the manufactured sheet 10 is provided to the user U via a store such as a retail store. In addition, the manufacturing of the sheet in the forming step (B) can also be performed in the store. In this case, the sheet layer forming device 40, the cutting device 50, and the processing device 60 are provided in the store, and the sheet 10 is manufactured while performing face-to-face sales such as consultation using the body surface information acquisition device Q, and the sheet 10 is provided to the user as a customer on the spot.

[0079] The providing method of the present embodiment, by including the above-described determining step (A) and the forming step (B), can provide the user U with the custom-produced sheet 10 determined in accordance with the intention of the user U. In particular, by the determining step (A), the shape and the size of the sheet are caused to reflect the intention of the user U using an interactive means such as the Internet, a graphical user interface (GUI), and the like, and thus a sheet that meets the expectations of the user U can be realized. Furthermore, in the forming step (B), the sheet layer is formed by the control of the discharge nozzle 41, and thus sheets of various shapes can be dealt with, and thus various demands of users can also be dealt with. That is, by including the above-described determining step (A) and the forming step (B), a sheet having a shape and a size that are appropriate for each user can be provided to each user. In addition, the providing method of the sheet of the present embodiment is effective when implementing a one-to-one production method of a sheet product.

[0080] In the providing method of the present embodiment, the sheet is formed by controlling the discharge nozzle 41, but instead of the discharge nozzle 41, the cutting device 50 can be controlled to form the sheet 10 having a shape and a size for each user, or the cutting device 50 can be controlled in addition to the discharge nozzle 41 to form the sheet 10 having a shape and a size for each user. For example, a laminated continuous sheet in which a continuous sheet 11 that is continuous and a continuous sheet layer 12 that is continuous to the base material layer 12 are laminated can be formed, and based on the information on the shape and the size of the sheet described above, a cutting unit such as a laser is moved, and the sheet having the desired shape is cut from the continuous laminated sheet. In this case, the above-described effects can also be realized. The cutting unit can use, in addition to a laser, a known cutting device such as a cutting device including a cutting roller in which a cutting blade extending in the circumferential direction is formed on the peripheral surface of the roller, and an anvil roller that receives the blade of the cutting roller, an ultrasonic cutting machine, and the like.

[0081] The sheet layer forming apparatus 40 used in the present embodiment will be described in detail. The sheet layer forming apparatus 40 includes a discharge nozzle 41 and a moving apparatus 42 for moving the discharge nozzle 41. The moving apparatus 42 in the sheet layer forming apparatus 40 is configured to move the discharge nozzle 41 in a planar direction. For example, the moving apparatus 42 includes a slide that holds the discharge nozzle 41, and rails along the X-axis direction and the Y-axis direction, respectively, and by moving the slide on the rails, the discharge nozzle 41 is moved in the X-axis direction and the Y-axis direction, i.e., in the planar direction. In addition, the moving apparatus 42 includes a Z-axis rail extending in the Z-axis direction, which is a vertical direction orthogonal to the X-axis direction and the Y-axis direction. By moving the slide on the Z-axis rail, the discharge nozzle 41 is moved up and down in the Z-axis direction, i.e., in the vertical direction. In this way, according to the moving apparatus 42, the discharge nozzle 41 is movable in the X-axis direction, the Y-axis direction, and the Z-axis direction. The moving apparatus 42 is controlled by the manufacturing control section 35. The sheet layer forming apparatus 40, while moving the discharge nozzle 41, discharges a raw material liquid containing a raw material of the sheet layer 11 from the discharge nozzle 41, and forms the sheet layer 11 into a predetermined shape and size. That is, in the forming step (B), the sheet forming section 300 forms the sheet 10 by moving the discharge nozzle 41 along a rail based on information on the shape and size of the sheet determined in the determining process step (A2-3), while discharging a raw material from the discharge nozzle 41. From the aspect of further realizing a sheet having a shape and size that reflects the user's intention, the above-described manner is preferable. The moving rail of the above-described discharge nozzle 41 is a rail that becomes a rail along the plan view shape of the sheet layer 11, and such a rail can be set using, for example, software of a SEL generator (manufactured by IAI Corporation) or the like.

[0082] The sheet providing method of the present embodiment can form a sheet having a two-dimensional shape desired by the user by controlling the moving rail of the above-described discharge nozzle 41. From the viewpoint of forming a sheet having a three-dimensional shape desired by the user, the sheet providing method is preferably one that forms the sheet 10 by controlling either or both of the discharge amount of the raw material from the discharge nozzle 41 and the moving rail of the discharge nozzle 41 based on information on the shape and size of the sheet. By changing the discharge amount of the raw material and repeating the moving rail of the discharge nozzle 41, the three-dimensional shape of the sheet can be easily controlled by locally changing the thickness.

[0083] From the viewpoint of easily forming the sheet layer 11 having a desired three-dimensional shape, the sheet layer 11 preferably contains nanofibers. The sheet layer forming apparatus 40 of the present embodiment is a publicly known electrospinning apparatus that discharges a raw material while applying a voltage to form the sheet layer 11. The sheet layer forming apparatus 40 accumulates nanofibers generated from a raw material liquid containing a raw material of the sheet layer 11 on the continuous sheet 12a by an electrospinning method. The sheet layer 11 thus obtained contains fibers (nanofibers) generated from the raw material. The nanofibers are fibers having an extremely fine fiber diameter.

[0084] From the viewpoint of easily forming a sheet, the nanofibers have a fiber diameter of 0.1 μm or more, and preferably 0.5 μm or more when the fiber diameter is expressed as a diameter of a circle.

[0085] In addition, from the viewpoint of improving the followability to the skin at the time of attaching the sheet, the fiber diameter is 6 μm or less, preferably 4 μm or less, more preferably 2 μm or less, and further preferably 1 μm or less.

[0086] Regarding the fiber diameter of the fibers, 300 fibers are arbitrarily selected after removing defects such as a lump of fibers, a cross section of fibers, and a polymer droplet from a two-dimensional image observed by a scanning electron microscope (SEM), and the length when a line orthogonal to the length direction of the fibers is drawn is taken as the fiber diameter. The arithmetic mean of the fiber diameters is taken as the average fiber diameter.

[0087] The sheet layer forming apparatus 40 can manufacture the sheet layer 11 to have a region (tapered region) in which the thickness gradually increases from the peripheral edge end of the sheet layer 11 toward the inside. The sheet layer 11 having this three-dimensional shape is less likely to be seen in a state of being attached to the skin. Thus, the sheet layer 11 having different thicknesses preferably has a thickness within the above range.

[0088] The sheet layer 11 having a tapered region, i.e., the sheet layer 11 having different thicknesses can be formed by controlling either or both of the discharge amount of the raw material from the discharge nozzle 41 and the moving track of the discharge nozzle 41 so that the accumulation amount of the nanofibers differs at each position, i.e., adjusting the accumulation distribution of the nanofibers. Hereinafter, the manufacturing method of the sheet layer 11 will be described in detail. The manufacturing method includes a track calculation step of determining the moving track of the discharge nozzle 41 and an accumulation step of accumulating the raw material (nanofibers) based on the moving track. In the present embodiment, the track calculation step is performed by the manufacturing data derivation section 33, and the accumulation step is performed by the sheet layer forming apparatus 40.

[0089] In the track calculation step, a moving track of the discharge nozzle 41 is determined based on a correlation between factors regarding the accumulation distribution of the nanofiber and the thickness of the nanofiber that is accumulated. The moving track is a track for forming the sheet layer 11 having a tapered region and having a prescribed planar shape and a prescribed thickness. The "prescribed planar shape" is a shape based on information of the shape and size of the sheet determined in the determination processing step (A2-3). The "prescribed thickness" is a set value determined based on product specifications and the like regarding the function and properties of the sheet, and can be a minimum thickness or a maximum thickness of the sheet layer 11, or a minimum thickness or a maximum thickness of the tapered region.

[0090] The accumulation distribution of the nanofiber in the track calculation step is a distribution of the amount of accumulation of the nanofiber that is accumulated on the continuous sheet 12a of the base material layer. As the factors regarding the accumulation distribution of the nanofiber, for example, the moving speed of the discharge nozzle 41, the discharge speed of the raw material liquid, the potential difference between the discharge nozzle 41 and the continuous sheet 12a of the base material layer, the distance between the discharge nozzle 41 and the continuous sheet 12a of the base material layer, the inner diameter of the discharge nozzle 41, and the material of the discharge nozzle 41 can be listed, and one or two or more of these can be selected and combined. Each of the factors can increase or decrease the thickness of the sheet layer containing the nanofiber by adjusting the value thereof.

[0091] For example, in the case where the moving speed of the discharge nozzle 41 (hereinafter also referred to as factor a), the discharge speed of the raw material liquid (hereinafter also referred to as factor b), and the distance between the discharge nozzle 41 and the continuous sheet 12a of the base material layer (hereinafter also referred to as factor c) are adopted as the factors regarding the accumulation distribution of the nanofiber, the amount of accumulation of the nanofiber per unit area can be increased or decreased according to the moving speed of the discharge nozzle 41 (factor a) or the discharge speed of the raw material liquid (factor b), and the thickness of the nanofiber that is accumulated can also be increased or decreased. In addition, the area of the accumulation body of the nanofiber per unit time can be increased or decreased according to the distance between the discharge nozzle 41 and the continuous sheet 12a of the base material layer (factor c). In this way, the factors a to c become factors that change the accumulation distribution of the nanofiber.

[0092] In the orbit calculation step, the orbit is set so that the above-described factors a to c and the correlation with the thickness of the accumulation body of the nanofiber are reflected to the prescribed planar shape, that is, the planar shape of the sheet layer 11 based on the information on the shape and size of the sheet determined in the determination processing step (A2-3). The above-described correlation is obtained by setting the factors on the accumulation distribution of the nanofiber to prescribed values, producing a test body of the nanofiber while moving the discharge nozzle 41 on a prescribed orbit, and measuring the thickness distribution of the test body, and is generally obtained in advance at the time of manufacturing the sheet layer 11. The above-described correlation can be obtained, for example, in the following manner. After setting the above-described factors a to c to prescribed values, a test body of the nanofiber is produced while moving the discharge nozzle 41 in one direction, and thickness data (hereinafter, also referred to as simulation data) in a cross section orthogonal to the extending direction of the test body is acquired. Such simulation data can be obtained, for example, by measurement using the above-described laser type three-dimensional shape measuring system. Based on the simulation data and the planar shape of the sheet layer 11 (the prescribed planar shape), the thickness of the nanofiber that can be formed is simulated, and the moving orbit is determined. As the simulation data, data in which the set values of the above-described factors a to c are the same, or a plurality of data in which the set values of the factors on the accumulation distribution of the nanofiber are different can be used.

[0093] In the orbit calculation step, the orbit is calculated by adjusting the values of the factors on the accumulation distribution of the nanofiber (for example, the above-described factors a to c), or providing a portion in which the accumulation position of the nanofiber is repeated, or a portion in which the accumulation position of the nanofiber is not repeated, on the moving orbit, in such a manner that the prescribed thickness of the nanofiber sheet becomes a set value. In addition, the calculated moving orbit is an orbit having a portion along the planar shape of the sheet layer 11 (the prescribed planar shape) based on the information on the shape and size of the sheet determined in the determination processing step (A2-3). Such an orbit can be set, for example, using the above-described SEL generator or the like. The moving orbit calculation step repeatedly performs the calculation of the moving orbit, that is, the simulation of the moving orbit, until a moving orbit having a portion along the prescribed planar shape and satisfying the condition that the thickness of the nanofiber becomes a prescribed value is obtained.

[0094] As the moving orbit determined in the orbit calculation step, for example, a combination of a group of orbits in which a plurality of orbits each of which is substantially similar in shape are nested, and a turnout that links the above-described plurality of orbits to each other, or a linear orbit that can be drawn in one stroke, or the like can be cited.

[0095] In the depositing step, the discharge nozzle 41 is moved based on the movement track determined in the track calculating step, and the nanofiber is deposited. In the present embodiment, data of the movement track determined in the track calculating step is sent to the manufacturing control section 35, and the movement device 42 is actuated based on the operation signal sent from the manufacturing control section, so that the discharge nozzle 41 is moved along the movement track. By moving the discharge nozzle 41 along the movement track in this way, a nanofiber layer having a prescribed plan view shape and having a thickness simulated in the setting of the movement track can be formed.

[0096] The production method of the present embodiment provides a sheet containing nanofiber, but can also provide a sheet capable of forming a film without particular limitation. By "capable of forming a film", for example, the following cases can be cited: a coating film can be formed by spreading a raw material in a liquid state and then drying it; or a film can be formed by depositing nanofiber containing a polymer compound capable of forming a fiber. From the viewpoint of appearance or tightness in the state of being attached to the skin, the sheet is preferably a film of a deposited body containing nanofiber, or a film of a deposited body containing the nanofiber.

[0114] The system 100 includes the above-described sheet specification determining section 200 and the sheet forming section 300. The sheet specification determining section 200 and the sheet forming section 300 can each use a publicly known general-purpose computer. The general-purpose computer includes a CPU, a ROM, a RAM, a HDD (Hard Disk Drive), and the like.

The above-described processing can be realized by an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array), or can be realized by a combination of an ASIC and an FPGA.

[0115] In addition, in the sheet specification determination unit 200, it is not necessary to set up dedicated software and hardware for system 100, on-premise type server structure, or OS (Operating System), but to use SaaS (Software as a Service), PaaS (Platform as a Service), or IaaS (Infrastructure as a Service) that utilize cloud servers.

[0116] The sheet specification determination unit 200 is connected to the aforementioned information terminal P and body surface information acquisition device Q via network N. The sheet specification determination unit 200 is also connected to the sheet forming unit 300 via network N. In this embodiment, the information terminal P or the body surface information acquisition device Q contains the application program (hereinafter also referred to as "application") used in this system 100. Information transmission and reception between the sheet specification determination unit 200 and the information terminal P can also be performed via a general web browser.

[0117] In this embodiment, the sheet specification determination unit 200 is a cloud server, and the sheet forming unit 300 is a general-purpose computer located at the manufacturing location where the sheet is manufactured (see reference). Figure 3 ).

Furthermore, the communication unit 21 sends the information generated or processed by the sheet information generation unit 22, the input information analysis unit 24, and the order information generation unit 28 to the information terminal P, the body surface information acquisition device Q, or the sheet forming unit 300.

[0120] The sheet information generation unit 22, in accordance with the access information received by the communication unit 21, sends information for obtaining information about the user's body surface, such as consultation information about skin problems, to the information terminal P or the body surface information acquisition device Q. For example, such as... Figure 4 The information on the selection operation screen shown in (a) and such as Figure 4 The information from the adjustment operation screen shown in (b) is transmitted via the communication unit 21 to the information terminal P or the body surface information acquisition device Q. Additionally, the sheet information generation unit 22 transmits information such as candidate sheet information, which is used to acquire information about the sheet for which the shape and size have been set for each user. In this embodiment, the sheet information generation unit 22, in response to the operation request signal sent from the input information analysis unit 24, transmits information from both the selection operation screen and the adjustment operation screen to the information terminal P.

[0121] The input information analysis unit 24 calculates the type, shape, or size of the sheet 10 based on information about the user's body surface. In this embodiment, the input information analysis unit 24 includes a consultation information analysis unit 241 and a sheet size calculation unit 245, each performing the aforementioned calculations. Specifically, based on information from the user's consultation, the consultation information analysis unit 241 performs calculations to select one or more suitable candidate sheets from a variety of sheets. For example, if the user inputs the information "the pores on my cheeks are noticeable" into the information terminal P, based on this information, a calculation is performed to select a sheet with light-transmitting properties for concealing pores from a variety of sheets (sheet products) stored in the storage unit D1. Additionally, the consultation information analysis unit 241 performs calculations to select a sheet with a shape suitable for adhering to the cheeks. Furthermore, from the results of these calculations, a sheet that "conceals pores" and "is suitable for adhering to the cheeks" is selected as a candidate sheet. Based on the user's consultation results, the consultation information analysis unit 241 extracts information on candidate sheets with specified functions, properties (hereinafter referred to as "properties, etc.") and shapes, and sends this information to the sheet information generation unit 22. The sheet information generation unit 22 displays the candidate sheet information and sends information to the information terminal P about a selection operation screen for the user to determine the type of sheet. The user operates the selection operation screen to select the sheet to be attached from the candidate sheets, determining the properties, etc. and shape of the sheet to be attached. Information on the sheet with determined properties, etc. and shape is sent to the sheet size calculation unit 245 and then to the order information generation unit 28.

[0122] In order to determine the attachment position and size of a sheet with its properties and shape already determined, the sheet size calculation unit 245 acquires information about the body surface and calculates the sheet size based on this information. For example, the sheet size calculation unit 245 requests information about the body surface from the information terminal P or the body surface information acquisition device Q. In this embodiment, as information about the body surface, image data of the attachment area of ​​the sheet is requested. This image data can be acquired through the imaging function of the information terminal P or the body surface information acquisition device Q. The acquired information about the body, such as the image data, is then sent to the sheet size calculation unit 245.

[0123] The sheet size calculation unit 245 identifies the area where the sheet is to be attached based on information about the body surface. For sheets with pre-determined properties and shapes, it allows the user to determine the attachment position and size. In this embodiment, the sheet size calculation unit 245 first identifies the attachment area of ​​the sheet in the image data, and then requests the sheet information generation unit 22 to adjust the attachment position and size of the sheet in the image data. The sheet information generation unit 22 receives an operation request signal from the sheet size calculation unit 245 regarding the request and sends an adjustment operation screen to the information terminal P or the body surface information acquisition device Q. The user operates the adjustment operation screen to determine the attachment position of the sheet in the image data and the size of the sheet at that attachment position (see reference). Figure 5 (a) and (b)). The information on the size of the sheet in the determined image is sent to the sheet size calculation unit 245. The sheet size calculation unit 245 performs calculation processing to calculate the size of the sheet based on the information on the size of the sheet in the image. Such processing methods can be adopted without particular limitation, using methods that can derive the actual size of the user U's face and the size of the sheet from the image. Specifically, known methods such as the following can be listed: a method of simultaneously taking pictures with a patch of a predetermined size as a scale and calculating the size of the sheet based on the scale; a method of calculating the size of the sheet based on the average size of the facial organs of a person (the average size of a person's eyes and mouth or the average length between a person's eyebrows, etc.) to estimate the size of the facial organs of the user U in the image (the size of the user U's eyes and mouth or the length between a person's eyebrows, etc.); and a method of calculating the size based on geometric information (e.g., epipolar geometry) obtained from images taken by multiple cameras. The facial organs of the user U in the image can be identified or extracted based on image data (e.g., color information such as pixels in the image data). The information of the processing result is stored in the storage unit D1 and sent to the order information generation unit 28.

[0124] Further, the input information analysis section 24 can calculate the kind, shape, or size of the sheet 10 by a method other than the above-described processing method. Specifically, the following is described as an example: the storage section Dl of the sheet specification determination section 200 stores a "sheet model", a plurality of "face models", and a "shape database of each sheet, and the input information analysis section 24 has a "renderer" as a function thereof.

[0125] The "sheet model" is a model in which the shape of the sheet is simplified, and can change in size in response to the operation of the user U. The initial value of the shape of the sheet model is any value set in the shape database as described later. The sheet model can be deformed into an arbitrary shape after the fact, and various parameters for deformation are set. That is, the deformation of the sheet model can be achieved by changing the parameters.

[0126] The "face model" is three-dimensional shape information indicating a standard face shape of a human body. The face model is prepared in a plurality of types according to race, gender, and age, and can be appropriately selected according to the attributes of the user. The shape information of the face model is also accompanied by information of the parts of the face. For example, three-dimensional coordinate values of the eyes, nose, mouth, and ears in the face model are set. Further, the eyes, nose, mouth, and ears will be collectively referred to as "face organs" hereinafter.

[0127] The "renderer" is software capable of arranging a plurality of models and light sources on a virtual three-dimensional space, and obtaining an image, that is, a rendering image, obtained by observing the models from an arbitrary viewpoint. The renderer is also referred to as rendering software, rendering engine, or the like. The renderer has a function of arranging other models along the surface of a model. For example, it is possible to arrange the sheet model on an arbitrary surface of the face model, and to render only the sheet model from an arbitrary viewpoint. Therefore, by displaying, that is, superimposing, the image of the sheet model subjected to rendering on the face image F, that is, by overlaying, it is possible to confirm the state in which the product sheet is actually attached to the face.

[0128] The "shape database" is a database indicating the relationship between the position of the face to which the sheet is to be attached and the shape of the sheet, and records each attachment position (attachment site) in the face and the shape suitable for the attachment position in correspondence with each other. The attachment position is expressed as the range of three-dimensional coordinates of the region in the face model, for example. The shape of the sheet stored in the shape database refers to the three-dimensional shape of the sheet set as an initial value, and a plurality of shapes are set in advance.

[0129] Table 1 described below is an example of the shape database. As described above, in the shape database, the correspondence relationship between the attachment position of the sheet and the shape of the sheet is defined. The information shown in Table 1 is all conceptual. The "eyelid" shown in Table 1 is actually a specific range of three-dimensional coordinates indicating the region below the eyes in the face model. Further, the "red bean type" shown in Table 1 is a shape having a region in the shape of a red bean, for example, in the face model. Figure 1a shape parameter of a three-dimensional specific sheet model of the illustrated shape.

[0130] In Table 1 below, a part of the list of the attachment position and the sheet shape corresponding thereto is omitted by "…".

[0131] [Table 1]

[0133] The processing performed by the input information analysis section 24 in the manner having the above-described renderer will be described later using the flowchart shown in Figure 9 and Figure 10 The flowchart shown in FIG. 8 will be described.

[0134] The information utilization section 26 performs the above-described processing on the machine learning in the step of optimizing the shape and size of the sheet by the machine learning. The machine learning uses the learning data accumulated by the sheet specification determination section 200. Specifically, a model for machine learning for optimizing the operation processing performed by the input information analysis section 24 is generated from the access information stored by the communication section 21, and the program of the operation processing performed by the input information analysis section 24 is updated by the machine learning. The information utilization section 26 of the present embodiment includes a feature component extraction section 261 and a learning result judgment section 263, and the machine learning is performed by these sections. The feature component extraction section 261 extracts features required for the machine learning from the access information stored in the storage section Dl, and the order information and the ordered sheet information stored in the customer information storage section D3 described later. This feature component extraction section 261 can extract information that becomes an index for the machine learning by using a machine learning algorithm such as principal component analysis and a neural network. The learning result judgment section 263 performs arbitrary machine learning based on the information extracted by the feature component extraction section 261, constructs a model for machine learning based on the extracted information, and reflects it to the operation processing performed by the input information analysis section 24. For example, the feature component extraction section 261 traces the consultation information on a plurality of users for a certain period, classifies the troubles of the skin for each category (for example, dryness, pores, wrinkles, dullness, and the like), and extracts the frequency of each category and information on the kind of the sheet ordered by the user. The learning result judgment section 263 learns the kind of the ordered sheet for each category based on the above-described frequency and the correlation of the kind of the ordered sheet using a machine learning algorithm such as a linear support vector machine (linear SVM), a k-nearest neighbor algorithm, and the like, and reflects it to the parameters and coefficients and the like of the operation processing performed by the input information analysis section 24. In the present embodiment, the database generated by the feature component extraction section 261 and the model for machine learning generated using the machine learning algorithm are stored in the learning data storage section D2.

[0135] The order information generating section 28 generates information on the sheet determined in shape and size for each user (hereinafter also referred to as "order sheet information") and order screen information based on the operation processing result of the input information analyzing section 24. The order sheet information is information on the kind, shape and size of the sheet determined as described above, information on the identification number (model number) of the sheet, and the like. The order screen information is information on an order screen for ordering the sheet, which is displayed on a display section of the information terminal P or the body surface information acquisition apparatus Q. The order screen is an operation screen for inputting order information such as the delivery destination of the sheet, the desired delivery date, the number of sheets, and the like by the user or the like. The order screen information generated by the order information generating section 28 is transmitted to the information terminal P or the body surface information acquisition apparatus Q via the communication section 21.

[0136] In addition, the order information generating section 28 generates customer information data in which order history data of the order information input by the user or the like is summarized for each user, and saves the customer information data in the customer information storage section D3, and transmits the order information and the order sheet information to the sheet forming section 300 via the communication section 21. As shown in, for example, Figure 7 the customer information storage section D3 stores, for each user, personal information such as the name and address of the user, and order history data obtained by associating the sheet ordered by the user in the past with order history data including the consultation information for ordering the sheet and the attachment position of the sheet, and the like. The order sheet information transmitted to the sheet forming section 300 is information on the shape and size of the sheet determined as described above, information on the model number for identifying the sheet having the shape and size, and the like. In addition, the order information transmitted to the sheet forming section 300 is information on the delivery destination of the sheet and the order number of the sheet for printing on the package, and the like. The customer information data in the customer information storage section D3 is used for the machine learning described above.

[0137] The storage section D1 stores various programs, data, parameters, and the like required when the sheet specification determining section 200 performs operation and processing by the control of each of the communication section 21, the sheet information generating section 22, the input information analyzing section 24, the information utilizing section 26, and the order information generating section 28. The storage section D1 stores, in addition to the input information such as the access information and the order information described above, output information and the like transmitted to the information terminal P, the body surface information acquisition apparatus Q, or the sheet forming section 300 via the communication section 21.

[0138] The storage section Dl, the learning data storage section D2, and the customer information storage section D3 can each use a database system or a file system. The storage section Dl, the learning data storage section D2, and the customer information storage section D3 each include, for example, a main storage device composed of a ROM and a RAM, an auxiliary storage device composed of a nonvolatile memory or the like, an HDD, an SSD (Solid State Drive), a flash memory, or the like.

[0139] Here, as the sheet specification determining section 200, a case including the communication section 21, the sheet information generating section 22, the input information analyzing section 24, the information utilizing section 26, the order information generating section 28, the storage section Dl, the learning data storage section D2, and the customer information storage section D3 is explained, but it is not necessary to include all of these configurations, and it is possible to execute the above-described information acquisition step (Al) of acquiring information about the body surface of each user and the shape and size determining step (A2) of determining the shape and size of the sheet 10 of each user based on the information, as long as the communication section 21, the sheet information generating section 22, and the input information analyzing section 24 are included.

[0140] The sheet forming section 300 includes, in addition to the above-described sheet layer forming device 40, the cutting device 50, and the processing device 60, the communication section 31, the manufacturing data exporting section 33, the manufacturing control section 35, and the information imparting section 37.

[0141] The communication section 31 receives the order information and the order sheet information transmitted from the sheet specification determining section 200 via the network N.

[0142] The manufacturing data exporting section 33 exports manufacturing information for manufacturing the sheet based on the information of the shape and size of the sheet in the order sheet information received by the communication section 31. The manufacturing information for manufacturing the sheet is control information of the sheet layer forming device 40, the cutting device 50, and the processing device 60 based on the shape and size of the sheet. In the present embodiment, the above-described manufacturing information is information about movement control of the discharge nozzle 41, control of the discharge amount of the raw material, or cutting for cutting into a desired shape.

[0143] The information about the movement control of the discharge nozzle 41 includes, for example, information indicating the movement track of the discharge nozzle 41 in coordinates including an X axis and a Y axis, information of the movement speed of the discharge nozzle 41 (the above-described factor a), or information of the distance between the discharge nozzle 41 and the continuous sheet 12a of the base material layer (the above-described factor c), or the like. The information indicating the movement track of the discharge nozzle 41 is information about the “predetermined plan view shape” of the sheet layer 11, and the outer edge portion of the movement track is reflected to the contour shape of the sheet layer 11.

[0144] The information on the control of the discharge amount of the raw material is, for example, the discharge amount of the raw material set at each position of the coordinates including the X-axis and the Y-axis. The discharge amount is the discharge amount per unit area or the discharge amount per unit time (the above-mentioned factor b).

[0145] The information on the cutting control is, for example, information indicating a moving track of laser processing.

[0146] The information on the movement control of the discharge nozzle 41 and the information on the control of the discharge amount of the raw material can be calculated in the above-mentioned track calculation step by simulation of a moving track having a prescribed plan view shape and satisfying a condition that the thickness becomes a prescribed value, on the basis of the information on the shape and the size of the sheet. That is, the manufacturing data derivation section 33 derives the information on the movement control of the discharge nozzle 41 and the information on the control of the discharge amount of the raw material on the basis of the information on the shape and the size of the sheet, by executing the above-mentioned track calculation step.

[0147] In addition, the manufacturing data derivation section 33 derives the information on the cutting control on the basis of the information on the shape and the size of the sheet. For example, a track along the contour of the sheet layer 11 at a position deviated outward from the sheet layer 11 from the contour (the peripheral edge end 17) of the sheet layer 11 is derived on the basis of the information on the shape and the size of the sheet. When laser processing is performed along the track on the continuous sheet 12a of the base material layer 12, a base material layer 12 having a substantially similar shape to the plan view shape of the sheet layer 11 can be cut from the continuous sheet 12a.

[0148] The manufacturing control section 35 controls the sheet layer forming device 40, the cutting device 50, and the processing device 60 possessed by the sheet forming section 300 on the basis of the manufacturing information derived by the manufacturing data derivation section 33. The manufacturing control section 35 of the present embodiment includes a nozzle movement control section 351 which controls the movement of the discharge nozzle 41 of the sheet layer forming device 40, a raw material discharge amount control section 353 which controls the discharge amount of the raw material of the discharge nozzle 41, a cutting control section 354 which controls the cutting device 50, and a processing control section 356 which controls the processing device 60. Each section possessed by these manufacturing control sections 35 controls the sheet layer forming device 40, the cutting device 50, or the processing device 60 on the basis of the manufacturing information derived by the manufacturing data derivation section 33.

[0149] The information-imparting section 37 imparts the identification information of the sheet to the manufactured sheet based on the order information received by the communication section 31. The identification information is information such as an identifier and a manufacturing number of the sheet, which can identify each sheet. The identification information can be represented by, for example, characters, numbers, symbols, or a combination thereof, or can be information displayed in an electronically readable manner. As the electronically readable display manner, for example, a two-dimensional code such as a bar code or a QR code (registered trademark), an electronic information medium such as an RFID (Radio Frequency Identification) tag, or the like can be used. The RFID tag can be read by an RFID reader (RFID antenna). In addition, the information-imparting section 37 imparts the order information such as the delivery destination to the package body in which the sheet is packaged, or the like.

[0150] Next, the processing performed by the system 100 of the present embodiment is described in accordance with the determination step (A) and the formation step (B) included in the sheet provision method of the above-described embodiments. Figure 8 A sequence diagram representing the processing performed by the system 100 in the above-described determination step (A).

[0151] In the determination step (A), when the information terminal P starts the application used in the present system 100 (step S1), the sheet specification determination section 200 is requested to display the consultation screen information of the consultation information (step S2). The consultation screen information is information of an operation screen in the form of a questionnaire or the like in which the user answers the troubles of the skin or the like. Next, the sheet information generation section 22 of the sheet specification determination section 200 transmits the consultation screen information to the information terminal P (step S3), and causes the display section of the information terminal P to display the operation screen based on the screen information. The user or the like performs an operation of inputting the troubles of the skin or the like based on the information displayed on the above-described operation screen. The input information input by the operation is transmitted from the information terminal P to the input information analysis section 24 of the sheet specification determination section 200 (step S4). Next, the input information analysis section 24 selects a single or a plurality of sheets having appropriate properties or the like and shapes from among the plurality of sheets stored in the storage section D1 based on the above-described input information (step S5), transmits the sheets to the sheet information generation section 22 as candidate sheets, and transmits an operation request signal for causing the user to select the sheet to be attached from among the candidate sheets (step S6). The processing of step S5 is performed by the consultation information analysis section 241 (not shown). Next, the sheet information generation section 22 presents the information of the candidate sheets, and transmits the information of the selection operation screen for causing the user to determine the kind of the sheet to the information terminal P (step S7). The user operates the selection operation screen, and selects the sheet to be attached from among the candidate sheets (refer to FIG. 6) (step S8). The selection operation screen is information of an operation screen in the form of a list or the like in which the user selects the sheet to be attached from among the candidate sheets. The input information of the selection operation screen is transmitted from the information terminal P to the input information analysis section 24 of the sheet specification determination section 200 (step S9). Next, the input information analysis section 24 selects the sheet to be attached from among the candidate sheets based on the above-described input information (step S10), and transmits the sheet to the sheet information generation section 22 (step S11). The sheet information generation section 22 transmits the sheet to the information terminal P (step S12), and causes the display section of the information terminal P to display the sheet (step S13). The user or the like confirms the sheet displayed on the information terminal P, and performs an operation of attaching the sheet to the skin (step S14). The operation of attaching the sheet to the skin is performed by, for example, the user or the like peeling the sheet from the information terminal P, and attaching the sheet to the skin. The operation of attaching the sheet to the skin is not limited to the above-described operation, and can be performed by, for example, the user or the like peeling the sheet from the information terminal P, and attaching the sheet to the skin by using a separate device such as a roller or the like. Figure 4The shape of the sheet to be attached is determined. Information on the shape of the sheet to be attached is transmitted to the input information analysis section 24 (step S8) and further transmitted to the order information generation section 28 (step S9).

[0152] Next, the input information analysis section 24 requests the information terminal P for image data of the attachment site of the sheet as information on the body surface (step S10). Thereby, a photographing mode is executed in the information terminal P (step Sll). The user uses the information terminal P in the photographing mode to take an image of the attachment site of the sheet such as the face. The image data is transmitted from the information terminal P to the input information analysis section 24 of the sheet specification determination section 200 (step S12). Thereby, information on the body surface is acquired. Next, the input information analysis section 24 identifies the face as the attachment site on the basis of the transmitted image (step S13). The process of step S13 is performed by the sheet size calculation section 245 of the input information analysis section 24 (not shown). Next, the input information analysis section 24, specifically the sheet size calculation section 245, transmits an operation request signal for adjusting the size of the sheet to the sheet information generation section 22 (step S14). The sheet information generation section 22 transmits information on an adjustment operation screen for causing the user to determine the size of the sheet to the information terminal P (step S15). The user operates the adjustment operation screen to perform an operation of adjusting the attachment position of the sheet and the size of the sheet at the attachment position (refer to FIG. 6). The information on the attachment position and the size of the sheet is transmitted to the input information analysis section 24 (step S16). On the basis of the information, the sheet size calculation section 245 (not shown) of the input information analysis section 24 derives the size of the sheet (step S17). Then, the information on the size is transmitted to the order information generation section 28 (step S18). Figure 5

[0153] ​The order information generating section 28 generates information on the sheet determined in shape and size for each user (order sheet information) (not shown) based on the information on the properties of the sheet and the like, the shape and the size sent from the input information analyzing section 24, and generates order screen information for ordering the sheet (step S19), and sends the order screen information to the information terminal P (step S20). Thus, an order screen for ordering the sheet is displayed on the display section of the information terminal P. The user inputs order information such as the delivery destination of the sheet, the desired delivery date, the number of sheets, and the like, according to the order screen. The input order information is sent to the order information generating section 28 (step S21), and the order information is stored in the customer information storage section D3 (step S22). After step S22, information indicating that the order of the sheet has been completed is displayed on the display section of the information terminal P (not shown). In addition, the order information generating section 28 sends the order information and the order sheet information to the sheet forming section 300 via the communication section 21 (not shown).

[0154] Next, the processing performed by the information terminal P and the sheet specification determining section 200 in steps S1 to S22 described above will be described with reference to a flowchart of the information terminal P shown in FIG. 27, by way of example, in a case where the sheet specification determining section 200 derives the sheet for hiding the color spot based on the information on the body surface (the image of the skin) sent from the information terminal P. Figure 9 and Figure 10

[0155] Figure 9 is a flowchart showing the processing of the information terminal P. The execution subject of each step described below is the CPU of the information terminal P.

[0156] In Figure 9 shown in step S551. The consultation information in the present embodiment includes the information on the trouble of the skin described above, and information on the age and the sex of the user U, and the like. The input of the consultation information can be performed using a character input function possessed by the OS of the information terminal P, or using voice input or gesture input.

[0157] In the next step S552, the face of the user U is imaged using a camera built in the information terminal P. Hereinafter, the image imaged in step S552 will be referred to as a "face image F". In the next step S553, the information obtained in steps S551 to S552 is uploaded to the sheet specification determining section 200 and step S554 is entered. The information uploaded in this step is the consultation information of the user U and the face image.

[0158] ​In step S554, a sheet image is received from the sheet specification determination unit 200. This sheet image is an image of the sheet derived by the sheet specification determination unit 200 based on consultation information (see step S505 described later). In the next step S555, for the face image F obtained in step S552, the sheet image received in step S554 is overlaid on the display unit of the information terminal P and displayed. In the next step S556, a user interface (user interface) is displayed to prompt the user U to make a selection, and the operation of the user U is judged. This user interface is an interface that allows the user to select any one of moving the sheet, changing the sheet size, and finishing the sheet adjustment (see step S555). Figure 4 (a) and (b)). For example, when user U drags a sheet (sheet image) displayed on the touch panel or operates a move button displayed on the display unit, it can be determined that the sheet has been moved. Additionally, when user U zooms in or out on the sheet (sheet image) displayed on the touch panel or operates a zoom in / out button displayed on the display unit, it can be determined that the sheet size has been changed. Furthermore, when the "Adjustment Complete" button displayed on the display unit is operated, it can be determined that the sheet adjustment has been completed. In step S556, if it is determined that user U has chosen to change the size, the process proceeds to step S557; if it is determined that the user has chosen to move the sheet, the process proceeds to step S558; and if it is determined that the user has chosen to complete the adjustment, the process proceeds to step S559.

[0159] In step S557, the size information of the sheet material, which has been changed by the user U's operation, is sent to the sheet material specification determination unit 200, and the process returns to step S554. The changed sheet material size information is, for example, a value representing the changed size when the current sheet material size is set to "100". "200" is sent when the size is magnified by 2 times, and "75" is sent when the size is reduced by 0.75 times.

[0160] In step S558, information regarding the amount of movement by user U is sent to the sheet specification determination unit 200, and the process returns to step S554. This amount of movement is the amount of movement in the X and Y directions on a two-dimensional plane displayed on the display unit.

[0161] In step S559, a dialog box for inquiring about the order quantity of sheet material is displayed on the display unit. In the next step S560, the input from user U is sent to the sheet material specification determination unit 200, and the process ends. Figure 9 The processing shown.

[0162] Figure 10 It means and Figure 9The flowchart below shows the processing of the corresponding sheet specification determination unit 200. The CPU of the sheet specification determination unit 200 is the main execution entity for each step shown below. When performing... Figure 9 When uploading information in step S553, start Figure 10 The processing is shown.

[0163] In step S500, the information terminal P acquires the uploaded information. In this step, it acquires consultation information including the user U's age and gender, and a facial image F. In the next step S501, the facial image F is used as the processing object for facial feature detection. Specifically, using pattern matching or a pre-learned cascade classifier, the eyes, nose, mouth, and ears in the facial image F are detected, and their coordinates in the facial image F are determined.

[0164] In the next step S502, based on the consultation information, the areas listed by user U as skin concerns (hereinafter referred to as "areas of concern") are detected from the facial image F. To perform this detection, the input information analysis unit 24 determines, based on the consultation information input by user U in step S551, which category (such as age spots, wrinkles, or loss of elasticity) the areas of concern should be classified into. Figure 10 (Not shown in the figure). The storage unit D1 in the sheet specification determination unit 200 pre-stores a database representing the relationship between the parts of interest and the aforementioned categories. Based on this database and the consultation information input by user U in step S551, it determines which category the parts of interest belong to. For example, based on the consistency between the input consultation information and the text related to the category, it determines which category the parts of interest belong to (pigmentation, wrinkles, elasticity, etc.). Then, the parts of interest in the face image F are detected. Taking the case where the part of interest is "pigmentation" as an example, the processing method for this detection will be explained. First, the face region is extracted from the face image F, and the average color of the colors other than the hair, eyes, mouth, eyebrows, etc., is calculated to obtain the average skin color of user U. Next, for each pixel of the face region in the face image F, the difference between it and the calculated average skin color (color difference) is calculated. Then, the obtained color difference information is binarized, and the point groups generated by the binarization process are grouped. Furthermore, based on the dispersion of the point clusters within each group, the group is classified into "blemishes" and "wrinkles." Specifically, groups with dispersion values ​​above a predetermined threshold are classified as "blemishes," and groups with dispersion values ​​below the predetermined threshold are classified as "wrinkles." Then, a group of point clusters that matches the category of the area of ​​interest is selected. That is, if the area of ​​interest is "blemishes," the group of "blemishes" is selected, and the center coordinates and coordinate regions of each point cluster classified into that group in the facial image F are calculated. The number of blemishes or wrinkles calculated in step S502 is not limited to a single one; multiple blemishes or wrinkles can also be calculated.

[0165] In the next step S503, the best face model is selected from a plurality of face models prepared in advance, based on the gender and age contained in the consultation information of the user U acquired in step S500.

[0166] In the next step S504, matching of the face model selected in step S503 and the face image F is performed. The coordinates of the facial organs in the face image F have been determined in step S501, so they are made to correspond to the three-dimensional coordinates of the facial organs set in advance in the face model.

[0167] In the next step S505, the positions of the color patches calculated in step S502 in the face model are determined using the matching results in the previous step, and the patch model (the shape of the patch) is determined with reference to the shape database stored in the storage Dl. Specifically, the center coordinates of each facial organ in the face image F have been determined in correspondence with the coordinates in the face model, so the coordinates of the color patches calculated in step S502 in the face image F can be converted into the coordinates in the face model by a method such as proportional interpolation. Then, by collating the converted coordinates in the face model with the shape database, the initial parameters of the patch model are determined. Thus, the attachment position of the patch in the face image F and the shape of the patch to be attached are determined. Further, the processing of this step is repeated only the same number of times as the number of color patches detected in step S502.

[0168] In the next step S506, a renderer in the input information analysis section 24 is activated, and the patch model is regenerated on the three-dimensional space managed by the renderer, with the patch model reading the initial parameters determined in step S505 (reading the initial values). That is, the initial parameters are reflected in the patch model. Further, in the case where a plurality of color patches are detected in step S502, the patch model is also generated in the same number and made to read the initial parameters corresponding to each color patch. At this time, the parameters can be adjusted so that the size of the patch model becomes the smallest size that covers the entire area of the color patch. The area in the face image F where the color patch exists has been calculated in step S502, so the area in the face model where the color patch exists can also be calculated using the same method as that for determining the three-dimensional coordinates of the center coordinates in the face model.

[0169] In the next step S507, the face model determined in step S503 is read onto the three-dimensional space managed by the renderer, and the center of the patch model is disposed at the position calculated in step S505. At this time, the renderer deforms the patch model along the surface of the face model. In this way, in step S507, the rendering of the patch model is performed using the renderer, and a rendered image is acquired. Further, the coordinates of the patch model on the same three-dimensional space as the face model are converted into the coordinates in the face image F in the reverse order to step S505 Figure 10(not shown).

[0170] In the next step S508, the rendering image and the coordinate value obtained in the step S507 are sent to the information terminal P. Further, the information sent in this step is received in the step S554 of the information terminal P. Figure 9

[0171] In the next step S509, the operation of the user U sent from the information terminal P in the step S556 is judged. In the case where the operation of the user U is judged to be the change of the size, the step S510 is entered, in the case where the operation of the user U is judged to be the movement of the sheet, the step S511 is entered, and in the case where the operation of the user U is judged to be the end of the adjustment, the step S513 is entered. For example, when the information of the changed size of the sheet is received, the operation of the user U is judged to be the change of the size, when the information of the movement amount of the sheet is received, the operation of the user U is judged to be the movement of the sheet, and when the information of the meaning that the end button is pressed is received, the operation of the user U is judged to be the end of the adjustment.

[0172] In the step S510, the parameter of the sheet model is updated based on the information of the changed size of the sheet received from the information terminal P, and the step S507 is returned to. For example, in the case where "200" is received as the value indicating the changed size of the sheet from the information terminal P in the step S557, the parameter is updated in such a manner that the size of the sheet model becomes twice.

[0173] In the step S511, the coordinate value obtained by adding the movement amount received from the information terminal P to the coordinate value calculated in the step S507 is converted into the coordinate in the face model, and the position of the sheet model is updated. The processing of the step S511 is performed in the same order as that of the step S505. In the next step S512, the shape of the sheet model whose position is updated in the step S511 is determined with reference to the shape database, the parameter is set, and the step S507 is returned to.

[0174] In the step S513, the input value of the order quantity sent from the information terminal P in the step S560 is received, and the processing shown in Figure 10 is ended.

[0175] The above-described Figure 9 and Figure 10 ​In the position size determination step (A2-2) of the processing by the system 100, the size of the sheet is updated in real time in accordance with the operation of the adjustment operation screen by the user U and displayed in the adjustment operation screen. Further, based on the position information (coordinates) of the color change portion such as the color spot in the face image F, the attachment position of the sheet and the size of the sheet are determined (steps S502 to S513), and thus, the operation such as the drag by the user U for determining the attachment position and the size can be simplified. In this way, the position information which becomes a candidate for the attachment position of the sheet (hereinafter, also referred to as "candidate position information") can also be displayed in the adjustment operation screen, and the user U can determine whether or not the position indicated by the candidate position information becomes the attachment position of the sheet. The candidate position information is generated based on the position information (coordinate information of the above point group) of the color change portion such as the color spot in the skin on the adjustment operation screen as in step S502.

[0176] Figure 11 is a flowchart showing the processing by the system 100 in the above forming step (B).

[0177] In the forming step (B), first, the order sheet information is sent from the sheet specification determining section 200 to the sheet forming section 300. Thereby, the sheet forming section 300 acquires the order sheet information (step S31). Next, the manufacturing data deriving section 33 of the sheet forming section 300 derives manufacturing information for manufacturing the sheet based on the information of the shape and size of the sheet in the order sheet information (step S32). The manufacturing information is sent to the manufacturing control section 35, and the nozzle movement control section 351 and the raw material discharge amount control section 353 control the discharge nozzle 41 to form the sheet layer 11 based on the manufacturing information (step S33). When the sheet layer 11 is formed in step S33, the cutting control section 354 controls the cutting device 50 to cut the continuous sheet 12a of the base material layer based on the above manufacturing information (step S34), and further, the processing control section 356 controls the processing device 60 to take out the manufactured sheet based on the above manufacturing information (step S35). The information assigning section 37 assigns the identification information to the above obtained sheet based on the order information and the order sheet information (step S36). Next, the sheet forming section 300 judges whether there is a remaining order sheet number for the sheet manufactured through steps S31 to S36 based on the order information (step S37). In the case where there is a remaining order sheet number in step S37, the process returns to step S32, and the process after step S32 is repeated. In the case where there is no remaining order sheet number in step S37, the process proceeds to step S38. Next, the sheet forming section 300 judges whether there is other order sheet information (step S38). In the case where there is other order sheet information in step S38, the process returns to step S31, and the process after step S31 is repeated. In the case where there is no other order sheet information in step S38, the process in the forming step (B) is ended. The sheet manufactured in this way is packaged into a package, and the package is assigned the order information such as the delivery destination by the information assigning section 37. The above package is delivered to the user based on the above delivery destination.
