[0013] The following describes in detail, with reference to the drawings, the contactless data transmitter / receiver label, the label sheet, and the method for manufacturing the contactless data transmitter / receiver label according to the embodiment.

[0014] [Contactless data receiver / transmitter label (IC label)] (First embodiment) Figure 1 is a plan view showing a contactless data transmitter / receiver label 10 according to the first embodiment. The contactless data transmitter / receiver label can be abbreviated as "IC label". In Figure 1, the inlet sheet 1, adhesive layer 3, cover sheet 7, and adhesive layer 8 are not shown. Figure 2 is a cross-sectional view of the IC label 10. Figure 2 is a cross-sectional view II of Figure 1.

[0015] As shown in FIG. 2, the IC label 10 includes an inlet sheet 1, a communication unit 2, an adhesive layer 3, an intervening sheet 4, a pseudo-adhesive layer 5, a release sheet 6, a cover sheet 7, and an adhesive layer 8.

[0016] The inlet sheet 1, the communication unit 2, the adhesive layer 3, the intervening sheet 4, the pseudo-adhesive layer 5, the cover sheet 7, and the adhesive layer 8 can be collectively referred to as a "laminated body 9". It can be said that the IC label 10 has a structure in which the laminated body 9 is attached to the release sheet 6.

[0017] The longitudinal direction (left-right direction in FIG. 2) of the inlet sheet 1 is the X direction. One direction in the X direction (right side in FIG. 2) is the +X side. The direction opposite to the +X side is the -X side. The short-side direction (up-down direction in FIG. 1) of the inlet sheet 1 is the Y direction. The Y direction is orthogonal to the X direction. One direction in the Y direction (upper side in FIG. 1) is the +Y side. The direction opposite to the +Y side is the -Y side. The Z direction is orthogonal to the X direction and the Y direction. Looking from the Z direction is referred to as a plan view. In the present embodiment, the vertical positional relationship is provisionally defined according to FIG. 2. The upper side (+Z side) in FIG. 2 is the upper side. The lower side (-Z side) in FIG. 2 is the lower side.

[0018] The inlet sheet 1 is formed in a rectangular shape in plan view. The inlet sheet 1 is in a rectangular shape in plan view. The length (dimension in the X direction) of the inlet sheet 1 is larger than the width (dimension in the Y direction). The -X side end of the inlet sheet 1 is the first end 1c. The +X side end of the inlet sheet 1 is the second end 1d.

[0019] The inlet sheet 1 may be, for example, a paper base material, a resin base material, or the like. Examples of the resin base material include polyester resins such as polyethylene terephthalate (PET). The -Z side surface of the inlet sheet 1 is the lower surface 1a (the first main surface). The surface opposite to the lower surface 1a of the inlet sheet 1 is the upper surface 1b (the second main surface).

[0020] As shown in Figure 1, the communication unit 2 includes an IC chip 11 and an antenna 12. The communication unit 2 is located on the lower surface 1a of the inlet sheet 1. The IC chip 11 can write and read information in a contactless manner via the antenna 12.

[0021] The antenna 12 is electrically connected to the IC chip 11. In this embodiment, the antenna 12 is formed in a rectangular annular loop shape in a plan view. For example, the antenna 12 is rectangular in shape with a longer side along the Y direction. Specifically, the antenna 12 has two first line portions 12a, two second line portions 12b, and a third line portion 12c. The base ends of the two first line portions 12a are electrically connected to the IC chip 11. The two first line portions 12a extend away from each other along the X direction, starting from the IC chip 11. The two second line portions 12b extend from the tips of the first line portions 12a toward the +Y side. The third line portion 12c is formed along the X direction and connects the tips of the two second line portions 12b.

[0022] The antenna 12 is formed from, for example, conductive ink, a thin metal film, a metal foil, a metal plate, etc. Examples of conductive inks include known polymer-type conductive inks and silver ink compositions. The thin metal film is formed by electroplating, electrostatic plating, metal vapor deposition, etc.

[0023] As shown in Figure 2, the position of the communication unit 2 in the X direction on the inlet sheet 1 is relatively close to the first end 1c. That is, the communication unit 2 is formed at a position where its distance to the first end 1c is smaller than its distance to the second end 1d. The position of the communication unit 2 is, for example, on the side of the first end 1c from the center in the longitudinal direction (X direction) of the inlet sheet 1 (a position slightly to the left of the center in Figure 2).

[0024] The adhesive layer 3 (first adhesive layer) is formed over the entire area of ​​the lower surface 1a of the inlet sheet 1. A known adhesive commonly used for labels can be used as the adhesive for the adhesive layer 3. The adhesive layer 3 adheres the inlet sheet 1 to the upper surface 4b of the interlining sheet 4 and the upper surface 6b of the release sheet 6.

[0025] The intervening sheet 4 is placed between the adhesive layer 3 and the release sheet 6. The intervening sheet 4 is rectangular in plan view. The dimension of the intervening sheet 4 in the X direction is smaller than the length (dimension in the X direction) of the inlet sheet 1. The dimension of the intervening sheet 4 in the Y direction is approximately the same as the width (dimension in the Y direction) of the inlet sheet 1.

[0026] The intervening sheet 4 is provided on a part of the inlet sheet 1 in a plan view. The intervening sheet 4 is provided in the region encompassing the communication unit 2. For example, the intervening sheet 4 is superimposed on the region including the first end portion 1c of the inlet sheet 1.

[0027] The intervening sheet 4 may be, for example, a paper substrate, a resin substrate, etc. Examples of resin substrate materials include polyester resins such as polyethylene terephthalate (PET). The -Z side surface of the intervening sheet 4 is the bottom surface 4a (first main surface). The surface of the intervening sheet 4 opposite to the bottom surface 4a is the top surface 4b (second main surface).

[0028] The pseudo-adhesive layer 5 is formed over the entire area of ​​the lower surface 4a of the intervening sheet 4. The pseudo-adhesive layer 5 adheres the intervening sheet 4 to the upper surface 6b of the release sheet 6. When the pseudo-adhesive layer 5 is peeled off after being attached to the object (release sheet 6), its adhesive strength becomes lower than the adhesive strength at the time of attachment (when it was first attached to the object). Therefore, the pseudo-adhesive layer 5 is difficult to re-adhere to the object after being peeled off.

[0029] The adhesive strength of the pseudo-adhesive layer 5 can be measured, for example, in accordance with JIS K6854. The adhesive strength can be measured, for example, by the resistance value when the substrate is peeled from the object using a peel tester (Shimadzu Corporation's "Autograph AGSH") at a speed of 300 mm / min and a peel angle of 90° (i.e., T-shaped peel).

[0030] Examples of adhesives that constitute the pseudo-adhesive layer 5 include UV-curing varnish. Known pressure-sensitive adhesives may also be used as the adhesive.

[0031] The release sheet 6 is sized to encompass the entire inlet sheet 1 in a plan view. In this embodiment, the area of ​​the release sheet 6 is larger than the area of ​​the inlet sheet 1. The release sheet 6 is made of, for example, paper, a resin sheet, or the like.

[0032] The cover sheet 7 covers the upper surface 1b of the inlet sheet 1. The cover sheet 7 may be made of, for example, a paper substrate, a resin substrate, etc. The cover sheet 7 may be the same shape as the inlet sheet 1, for example.

[0033] The adhesive layer 8 (second adhesive layer) is formed over the entire area of ​​the lower surface 7a of the cover sheet 7. A known adhesive commonly used for labels can be used as the adhesive for the adhesive layer 8. The adhesive layer 8 adheres the cover sheet 7 to the upper surface 1b of the inlet sheet 1.

[0034] [Label Sheet] Figure 3 is a plan view of the label sheet 20 according to the embodiment. Figures 4 and 5 are schematic diagrams showing examples of how to use the label sheet 20. Figure 6 is a schematic diagram showing an example of how to use the IC label 10.

[0035] As shown in Figure 3, the label sheet 20 is composed of multiple IC labels 10 (see Figure 1) connected in the longitudinal direction (X direction). Adjacent IC labels 10 are connected at their longitudinal ends on the release sheet 6. The label sheet 20 comprises a long release sheet 6 and multiple laminates 9. The multiple laminates 9 are arranged in the longitudinal direction of the release sheet 6. Adjacent laminates 9 may be spaced apart in the longitudinal direction of the release sheet 6.

[0036] Multiple IC labels 10 are connected in an orientation where the communication unit 2 faces the -X side (one end) of the label sheet 20.

[0037] [How to use IC labels and label sheets] As shown in Figure 4, the label sheet 20 can be in the form of a roll (label roll 21). When using IC labels, the release sheet 6 of the label sheet 20 is taken up by the take-up roller 23 via the direction change roller 22, if necessary.

[0038] As shown in Figure 5, at least a portion of the partial region 9A (the portion including the -X side end) of the laminate 9 on which the intervening sheet 4 is formed is peeled off from the release sheet 6 using the direction changing roller 22. The adhesive strength of the pseudo-adhesive layer 5 decreases as it peels off from the release sheet 6. Since the rest of the laminate 9 is attached to the release sheet 6 by the adhesive layer 3, the laminate 9 is stably held on the release sheet 6 in a form in which the partial region 9A protrudes.

[0039] For example, a user can grasp a portion of the laminate 9 by pinching it in the thickness direction with their fingers and peel the laminate 9 off the release sheet 6. At this time, the pseudo-adhesive layer 5 has reduced adhesive strength and is less likely to stick to the fingers. Therefore, the operation of peeling off the laminate 9 becomes easy.

[0040] As shown in Figure 6, the peeled laminate 9 can be attached to the upper surface 30a of the object to be installed 30 by the adhesive layer 3. The laminate 9 may also be configured such that a portion of the region 9A protrudes from the object to be installed 30 (a configuration in which the portion of the region 9A does not overlap the object to be installed 30). In this configuration, since the communication unit 2 is not positioned to overlap the object to be installed 30, performance degradation of the communication unit 2 can be suppressed even if the object to be installed 30 contains metal. When the object to be installed 30 contains metal, the object to be installed 30 functions as a radiating unit, thereby improving the communication performance of the communication unit 2.

[0041] Even when the entire area of ​​the laminated body 9 is placed on top of the object 30 to be installed, the communication unit 2 is separated from the object 30 by the intervening sheet 4, thus suppressing a decrease in the performance of the communication unit 2.

[0042] [Method of manufacturing IC labels] An example of a method for manufacturing the IC label 10 (see Figure 1) will be explained with reference to Figures 7 to 9. Figures 7 to 9 are process diagrams showing the manufacturing method of the IC label 10.

[0043] (Step 1: Attaching the intervening sheet) As shown in Figure 7, the intervening sheet 4 is attached to the upper surface 6b of the release sheet 6 by the pseudo-adhesive layer 5. Therefore, the intervening sheet 4 can be stably held to the release sheet 6.

[0044] (Step 2: Attaching the inlet sheet) As shown in Figure 8, the inlet sheet 1, on which the communication unit 2 is provided, is attached to the upper surface 4b of the intervening sheet 4 and the upper surface 6b of the release sheet 6 by the adhesive layer 3. In this step, the inlet sheet 1 is attached so that the intervening sheet 4 is positioned in the area encompassing the communication unit 2.

[0045] (Step 3: Applying the cover sheet) As shown in Figure 9, the cover sheet 7 is attached to the upper surface 1b of the inlet sheet 1 by the adhesive layer 8. This yields the IC label 10 shown in Figure 1.

[0046] [Effects of the IC label and label sheet according to this embodiment] In this embodiment, the IC label 10 has an intervening sheet 4 in the area encompassing the communication unit 2. Therefore, when installing it on an object, the sheet does not need to be folded or otherwise positioned, and the communication unit 2 can be placed away from the object, thereby suppressing a decrease in the performance of the communication unit 2. Thus, the IC label 10 can be easily installed on an object.

[0047] The IC label 10 can be miniaturized because it allows for a smaller area of ​​the laminate 9 compared to cases where sheet folding or other modifications are required. Because the IC label 10 can be miniaturized, it also offers advantages in terms of manufacturing costs.

[0048] In the label sheet 20 according to this embodiment, multiple IC labels 10 are connected in a manner that the communication unit 2 faces the -X side (one end) (see Figure 3). Therefore, the laminate 9 can be stably held on the release sheet 6 in a form in which a partial region 9A has been peeled off from the release sheet 6 (see Figure 5). Thus, the laminate 9 can be peeled off the release sheet 6 by grasping the partial region 9A. Therefore, the operation of installing the laminate 9 on an object is made easy.

[0049] [Effects of the IC label manufacturing method according to this embodiment] According to the aforementioned method for manufacturing the IC label 10, when installing the inlet sheet 1, the intervening sheet 4 is placed in the area encompassing the communication unit 2. Therefore, the intervening sheet 4 can be placed in a predetermined position with simple operation. Thus, the IC label 10 can be easily manufactured.

[0050] [IC Label] (Second Embodiment) Figure 10 is a plan view showing the IC label 110 according to the second embodiment. In Figure 10, the inlet sheet 1, adhesive layer 3, cover sheet 7, and adhesive layer 8 are not shown. Figure 11 is a cross-sectional view of the IC label 110. Figure 11 is a cross-sectional view taken along line II-II of Figure 10.

[0051] As shown in Figure 11, the IC label 110 comprises an inlet sheet 1, a communication section 2, a radiating section 13, an adhesive layer 3, an intervening sheet 4, a pseudo-adhesive layer 5, a release sheet 6, a cover sheet 7, and an adhesive layer 8. The IC label 110 differs from the IC label 10 (see Figure 1) according to the first embodiment in that it has a radiating section 13. The inlet sheet 1, communication section 2, radiating section 13, adhesive layer 3, intervening sheet 4, pseudo-adhesive layer 5, cover sheet 7, and adhesive layer 8 can be collectively referred to as a "laminated structure 109".

[0052] The radiating portion 13 is provided on the lower surface 1a of the inlet sheet 1. In a plan view, the radiating portion 13 is formed at a position +X side of the intervening sheet 4. In a plan view, the radiating portion 13 has a rectangular shape with a pair of sides along the X direction and a pair of sides along the Y direction. For example, the radiating portion 13 has a rectangular shape with a longer side along the X direction. The width (Y-direction dimension) of the radiating portion 13 may be approximately the same as the width of the antenna 12.

[0053] The radiating section 13 is electrically connected to the antenna 12 via a bridge 14. The bridge 14 connects the central part of the second line section 12b (12b1) on the +X side to the -X end of the radiating section 13. The radiating section 13 and the bridge 14 are conductive. The radiating section 13 and the bridge 14 are formed from, for example, conductive ink, a thin metal film, a metal foil, a metal plate, etc.

[0054] [Effects of the IC label according to this embodiment] In this embodiment, the IC label 110 has an intervening sheet 4 in the area encompassing the communication unit 2. Therefore, similar to the IC label 10 in the first embodiment, it can be easily attached to an object.

[0055] The IC label 110 allows for a smaller area of ​​the laminate 109 compared to cases where sheet folding or other modifications are required, thus enabling miniaturization. Because the IC label 110 can be miniaturized, it also offers advantages in terms of manufacturing costs.

[0056] Since the IC label 110 has a radiating section 13, it can improve the communication performance of the antenna 12. The IC label 110 can ensure sufficient communication performance even if the object (installation target object 30) does not contain metal.

[0057] Although embodiments of the present invention have been described above, the configurations and combinations thereof in the embodiments are merely examples, and additions, omissions, substitutions, and other modifications to the configurations are possible without departing from the spirit of the present invention.

[0058] For example, in the IC label 10 shown in Figure 1, the antenna 12 is rectangular in shape, but the shape of the antenna is not particularly limited. The antenna may be circular, elliptical, polygonal, or the like. In the IC label 110 shown in Figure 10, the radiating portion 13 is rectangular, but the shape of the radiating portion is not particularly limited. The radiating portion may be circular, elliptical, polygonal, or the like.

[0059] The objects to which the stacked structure is installed can be any items that require information management. The objects to which the stacked structure is installed are not particularly limited; examples include jewelry, watches, furniture, toys, and electronic devices. [Explanation of symbols]
