Description

【Technical Field】 【0001】 The present invention relates to a continuous form paper in which a plurality of form pieces with RFID labels attached are continuous. 【Background Art】 【0002】 A continuous form paper formed by folding continuous form pieces in one direction in a bellows-like manner is generally called a fan-fold paper. Among such continuous form papers, those in which RFID labels are attached to each form piece are known. In each form piece of such a continuous form paper, since the arrangement part of the IC chip included in the RFID label bulges convexly, in the folded state of the continuous form paper, the pressure from the stacking direction is likely to concentrate on the arrangement part of the IC chip, and there is a problem that the IC chip is easily damaged. And in order to solve such a problem, for a plurality of form pieces that overlap in the same direction in the stacking direction, by shifting the attachment positions of the RFID labels to the front, rear, left, and right to reduce the number of IC chips overlapping in the stacking direction, it has been proposed to suppress the local thickening of the arrangement part of the IC chip in the folded state of the continuous form paper (see Patent Document 1). 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent No. 6475470 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 In conventional continuous form paper, the area on which RFID labels can be attached to each form piece may be limited due to specification constraints. In such cases, with the configuration described in Patent Document 1, it becomes difficult to shift the position of the RFID labels so that the IC chips of overlapping form pieces facing the same direction do not overlap in the stacking direction. Furthermore, even if RFID labels can be attached so that the IC chips do not overlap, if the IC chips cannot be sufficiently separated, the protrusions of the IC chip placement areas may interfere with each other, and the pressure applied to the IC chips from the stacking direction when folded may not be sufficiently reduced. 【0005】 This invention has been made in view of the current situation, and aims to provide a configuration that can suitably reduce the pressure applied to the IC chip of an RFID label, even when the area on which an RFID label can be attached to a continuous form of paper, on which form paper pieces with RFID tags attached are folded in an accordion-like manner, is limited. [Means for solving the problem] 【0006】 The present invention provides a continuous form paper comprising a plurality of form paper pieces that are continuous in one direction, and the form paper pieces are folded in an accordion-like manner at the boundaries of the form paper pieces, so that the form paper pieces are folded one by one or in groups, wherein an RFID label comprising an antenna and an IC chip connected to the antenna is affixed to one side of each form paper piece, and the plurality of form paper pieces that overlap in the same orientation in the stacking direction include a first group of form paper pieces to which a first RFID label is affixed and a second group of form paper pieces to which a second RFID label is affixed, and the first RFID label and the second RFID label are the same The continuous form paper comprises an antenna and the IC chip, and has the same planar shape, wherein in the second RFID label, the antenna and the IC chip are positioned offset in a predetermined direction from the first RFID label, and the first group of form paper pieces and the second group of form paper pieces, which overlap in the same orientation in the stacking direction, are arranged such that a part or all of the first RFID label and the second RFID label overlap in the stacking direction, and the IC chip of the first RFID label and the IC chip of the second RFID label do not overlap in the stacking direction. Here, the "stacking direction" of continuous form paper refers to the direction in which multiple pieces of form paper overlap when the continuous form paper is folded. 【0007】 In this configuration, the positions of the IC chips on the first and second groups of form pieces can be shifted without shifting the RFID label attachment positions on the first and second groups of form pieces in the front, back, left, or right directions. Therefore, when the continuous form paper is folded, it is possible to avoid the IC chips on the first and second groups of form pieces overlapping in the stacking direction. Thus, according to the present invention, even with continuous form paper where the area on which RFID labels can be attached to form pieces is limited, the number of IC chips that overlap in the stacking direction when folded can be reduced, thereby reducing the pressure applied to the IC chips. Furthermore, because the present invention uses the same antenna and IC chip for both the first and second RFID labels, it can be implemented at a relatively low cost, and there is no variation in performance between the first group of form paper fragments and the second group of form paper fragments. 【0008】 In a specific embodiment of the present invention, the RFID label is provided with an RFID inlet on one side of the inlet substrate, wherein the antenna and the IC chip connected to the antenna are arranged thereon, and in the second RFID label, the same RFID inlet as the first RFID label is positioned offset in a predetermined direction from the first RFID label. In this configuration, since the same RFID inlet is used for both the first and second RFID labels, the cost of the RFID labels can be reduced. 【0009】 In another specific embodiment of the present invention, the RFID label comprises an RFID inlet on one side of an inlet substrate, wherein the antenna and the IC chip connected to the antenna are disposed thereon, and the RFID inlet of the first RFID label and the RFID inlet of the second RFID label have the same planar shape of the inlet substrate, and in the RFID inlet of the second RFID label, the antenna and the IC chip are offset in the predetermined direction relative to the inlet substrate compared to the RFID inlet of the first RFID label. Even with this configuration, since the same antenna and IC chip are used in the first RFID label and the second RFID label, the present invention can be realized at a relatively low cost. 【0010】 In the present invention, a configuration is proposed in which the second RFID label on the second group of form paper fragments is affixed in a specific direction that intersects the predetermined direction at an acute angle with the first RFID label on the first group of form paper fragments. Even if the range in which RFID labels can be affixed to form paper fragments is limited, if it is possible to shift the affixing position to some extent, then by shifting the affixing position of the second group of RFID labels as in this configuration, the amount of misalignment between the IC chips of the first group of form paper fragments and the second group of form paper fragments that overlap in the stacking direction can be increased. 【0011】 Another aspect of the present invention is a continuous form paper comprising a plurality of form paper pieces that are continuous in one direction, and the form paper pieces are folded in an accordion-like manner at the boundaries of the form paper pieces, so that the form paper pieces are folded one by one or in groups, wherein an RFID label including an RFID inlet is affixed to one side of the paper surface of each form paper piece, and the plurality of form paper pieces that overlap in the same orientation in the stacking direction are a first group of form paper pieces to which a first RFID label is affixed and a second group to which a second RFID label is affixed The continuous form paper includes a form paper piece, wherein the second RFID label has the same RFID inlet as the first RFID label, but is arranged in the opposite direction to the first RFID label, and the first group of form paper pieces and the second group of form paper pieces, which overlap in the same direction in the stacking direction, are characterized in that a part or all of the first RFID label and the second RFID label overlap in the stacking direction, and the IC chip of the first RFID label and the IC chip of the second RFID label are arranged so that they do not overlap in the stacking direction. 【0012】 Even with this configuration, the positions of the IC chips on the first and second groups of form pieces can be shifted without shifting the RFID label attachment positions on the first and second groups of form pieces in the front, back, left, or right directions. This prevents the IC chips on the first and second groups of form pieces from overlapping in the stacking direction when the continuous form paper is folded. Therefore, according to the present invention, even with continuous form paper where the area on which RFID labels can be attached to form pieces is limited, the number of IC chips that overlap in the stacking direction when folded can be reduced, thereby reducing the pressure applied to the IC chips. Furthermore, in this configuration, since the same RFID inlet is used for both the first and second RFID labels, it can be implemented at a relatively low cost, and there is no variation in performance between the first group of form paper fragments and the second group of form paper fragments. 【0013】 In the present invention, it is proposed that the IC chips of the first group of form paper pieces and the second group of form paper pieces, which overlap in the same orientation in the stacking direction, are arranged such that they do not overlap with the antennas of the form paper pieces of the other group in the stacking direction, and at least a portion of the antennas of each group are arranged to overlap with the antennas of the form paper pieces of the other group in the stacking direction. 【0014】 On each sheet of paper, the area where the RFID label antenna is located is raised and thicker, though not as much as the area where the IC chip is located. Therefore, if the IC chip is positioned so that it does not overlap with the antenna of the other group in the stacking direction, as in this configuration, the thickness of the IC chip area in the folded continuous sheet of paper can be reduced by the amount of the antenna of the other group. On the other hand, regarding the antennas, if the antennas of the first and second groups of sheet of paper are positioned so that they overlap in the stacking direction, the thickness of that area in the folded continuous sheet of paper becomes relatively large, and pressure is more easily applied to that area from the stacking direction, thus distributing the pressure applied to the IC chip area. 【0015】 Furthermore, in the above configuration, it is proposed that the antenna is a multi-loop antenna, and that the jumper wires of the antenna are arranged in the portion where the antenna of the first group of form paper pieces and the antenna of the second group of form paper pieces overlap in the stacking direction. 【0016】 Jumper wires are formed to span both the inside and outside of the multi-loop antenna, and generally, in the multi-loop antenna of an RFID label, the area where the jumper wires are located is the thickest. Therefore, by including the area where the antennas of the first and second groups of form paper overlap, as in this configuration, pressure from the stacking direction is more easily applied to the overlapping area of ​​the antennas, making it possible to further reduce the pressure applied to the IC chip location. 【0017】 Also, in the present invention, the antenna is a multi-loop antenna, the IC chip is disposed inside the multi-loop wire of the antenna, and it is proposed that the multi-loop wire of the first group of form sheets and the multi-loop wire of the second group of form sheets are arranged so as to overlap in the stacking direction over the entire circumference of the multi-loop wire. 【0018】 In such a configuration, in the state where the continuous form paper is folded, the multi-loop antennas of the first group and the second group of form sheets that overlap in the same direction overlap in the stacking direction around the IC chip arrangement site, so that a relatively thick annular portion is formed so as to surround the IC chip arrangement site. Therefore, the pressure applied to the IC chip from the stacking direction can be uniformly dispersed around the IC chip. Note that the overlap between the multi-loop wires is not limited to the case where each individual wire constituting the multi-loop wire overlaps, and it is sufficient that at least a part of the bundle of wires constituting the multi-loop wire overlaps over the entire circumference. 【Effects of the Invention】 【0019】 As described above, according to the present invention, in the form sheets that are folded in a bellows shape and overlap in the stacking direction in the same direction, it is possible to shift the position of the IC chip of the RFID label without shifting the RFID label left, right, front, or back. Therefore, even when the attachable range of the RFID label to the form sheet is limited, the pressure received by the IC chip of the RFID label can be suitably reduced. 【Brief Description of the Drawings】 【0020】 [Figure 1] It is a developed view of the continuous form paper 1 of Example 1.

In the following embodiment, the first form paper piece 5a corresponds to the first group of form paper pieces according to the present invention, and the second form paper piece 5b corresponds to the second group of form paper pieces according to the present invention. Also, the first RFID label 11a corresponds to the first RFID label according to the present invention, and the second RFID labels 11b, 11c, and 11d correspond to the second RFID labels according to the present invention. Furthermore, in the following embodiments, the direction along the longitudinal direction of the continuous form paper (the continuous direction of the form paper pieces) will be described as the front-to-back direction of the form paper pieces, and the direction along the short direction (width direction) of the continuous form paper will be described as the left-to-right direction of the form paper pieces. However, the present invention is not limited to use in the directions thus defined. [Examples] 【0022】 As shown in Figure 1, the continuous form paper 1 of this embodiment consists of multiple form paper segments 5 arranged in a continuous direction. All form paper segments 5 are rectangular in shape and of the same size, and are arranged in the same orientation along the longitudinal direction of the continuous form paper 1. The continuous form paper 1 is made of a long, strip-shaped paper base material 3 made of high-quality paper or the like. Perforations 4 are formed along the boundaries of adjacent form paper segments 5 on the surface of the paper base material 3, crossing the paper base material 3 in the width direction, making it easy to bend and separate the paper base material 3 at the boundaries of each form paper segment 5. 【0023】 The continuous form paper 1 is fanfold paper, and as shown in Figure 2, by alternately folding it in a mountain fold and valley fold along the perforations 4 formed at the boundaries of the form paper pieces 5, it is folded into an accordion shape, as shown in Figure 3, so that the form paper pieces 5 are folded one by one on top of each other for transport and storage. When issuing a form using the continuous form paper 1 of this embodiment, the required information is printed on one or both sides of each form paper piece 5 using a printer or the like, and the printed form paper pieces 5 are separated along the perforations 4 and used as a form. The basic structure of this continuous form paper 1 can be based on known structures, so a detailed explanation is omitted. 【0024】 As shown in Figure 1, one roughly rectangular RFID label 11 is affixed to a designated label attachment area S on one side of each form piece 5. As shown in Figures 4 to 6, the RFID label 11 consists of an RFID inlet 12 and a protective sheet 13 that covers the RFID inlet 12. The RFID labels 11 affixed to the form pieces 5 consist of two types, a first RFID label 11a and a second RFID label 11b, as shown in Figures 5 and 6, but their basic configuration is the same. 【0025】 The RFID inlet 12 is a contactless, battery-less type that can transmit and receive signals such as commands and data non-contactually using HF band electromagnetic waves with an input / output device (reader / writer device) (not shown). As shown in Figure 4, the RFID inlet 12 consists of an antenna 16 and an IC chip 15 arranged on the front side (installation side) of a thin film inlet substrate 14. The inlet substrate 14 is made of a roughly rectangular PET film, and as shown in Figure 6, an adhesive 23 for attaching the inlet substrate 14 to the paper substrate 3 is applied to the back side of the inlet substrate 14. 【0026】 As shown in Figures 4-6, the antenna 16 is a multi-loop antenna in which a conductive wire is wound in a loop multiple times and is printed on the surface of the inlet substrate 14 with conductive paste. The antenna 16 consists of a multi-loop wire 19 in which a roughly rectangular annular loop is wound five times, a pair of terminal wires 20 extending inside the multi-loop wire 19, and a jumper wire 21 that straddles the multi-loop wire 19 and electrically connects the outer end of the multi-loop wire 19 to one of the terminal wires 20. The IC chip 15 is capable of electromagnetically storing required information and is placed on the terminal wires 20 and electrically connected to the antenna 16 by being bonded to the terminal wires 20 with an anisotropic conductive adhesive 17. 【0027】 As shown in Figures 4-6, the protective sheet 13 has a roughly rectangular shape in plan view. The protective sheet 13 may be made of PET film or paper, and a nearly uniform thickness of adhesive 24 is applied to its back side. The protective sheet 13 is larger in both length and width dimensions than the planar shape of the RFID inlet 12, and is attached to cover the entire front side (installation side) of the RFID inlet 12 via the adhesive 24 on the back, and is also attached to the paper substrate 3 around the periphery of the RFID inlet 12. 【0028】 As described above, the RFID label 11 according to this embodiment has a structure in which the surface of the RFID inlet 12 is covered with a protective sheet 13. However, as shown in Figure 4, the surface of the RFID inlet 12 is not flat, and there are undulations due to the IC chip 15 and antenna 16. Therefore, as shown in Figure 6, the surface of the RFID label 11 has irregularities that conform to the shapes of the IC chip 15 and antenna 16. Specifically, as shown in Figure 6, the outer periphery 25 where the protective sheet 13 is attached to the paper substrate 3 is the thinnest part of the RFID label 11. In contrast, the part 26 on the inlet substrate 14 where the IC chip 15 and antenna 16 are not disposed is thicker than the outer periphery 25 by the thickness of the inlet substrate 14. Furthermore, the parts 27 and 29 where the antenna 16 is disposed are thicker than the outer periphery 25 by the thickness of the inlet substrate 14 and the antenna 16. Furthermore, the IC chip 15 mounting area 28 is thicker than the outer periphery 25 by the thickness of the inlet substrate 14, the antenna 16 (terminal wire 20), and the IC chip 15. The antenna 16 is basically formed with a nearly constant thickness, but the jumper wire 21 is formed to straddle the multi-loop wire 19, so the mounting area 29 for the jumper wire 21 is thicker than the mounting areas 27 for the multi-loop wire 19 and the terminal wire 20. Thus, the surface of the RFID label 11 according to this embodiment has irregularities that conform to the shapes of the IC chip 15 and the antenna 16, and among them, the IC chip 15 mounting area 28 is significantly raised in a convex shape. Note that in Figures 4 and 6, the thickness of the RFID label 11 is shown to be thicker than it actually is for illustrative purposes, but the thickness of a typical RFID label 11 is 1 mm or less. 【0029】 The RFID labels 11 are attached one by one to each form paper piece 5 by adhesive 23, 24 applied to the RFID inlet 12 and protective sheet 13, so as to fit into a predetermined label attachment area S. The label attachment area S is a rectangular area slightly larger than the planar shape of the RFID label 11, and is provided in the same position on all form paper pieces 5. Specifically, as shown in Figure 1, the label attachment area S is located on one side of the longitudinal direction of one side of each form paper piece 5, and is in the center in the short direction. 【0030】 In this embodiment, as shown in Figure 3, in the accordion-folded continuous form paper 1, adjacent form paper pieces 5 overlap with their front and back sides facing each other via the perforations 4, and every other form paper piece 5 overlaps with its front and back sides facing the same direction in the stacking direction. Therefore, in the folded continuous form paper 1, the label attachment areas S of adjacent form paper pieces 5 do not overlap, but the label attachment areas S of the RFID labels 11 on every other form paper piece 5 overlap. Furthermore, as described above, the size of the label attachment area S is limited, and the attachment position of the RFID labels 11 cannot be shifted significantly, so the RFID labels 11 attached to every other form paper piece 5 overlap in the stacking direction. Specifically, in the continuous form paper 1 shown in Figure 3, the odd-numbered form pieces 5 from the bottom are stacked in the same orientation with the RFID label 11 facing upwards, and the RFID labels 11 attached to each form piece 5 overlap in the stacking direction on the right side of the figure. In contrast, in Figure 3, the even-numbered form pieces 5 from the bottom are stacked in the same orientation with the RFID label 11 facing downwards, and the RFID labels 11 attached to each form piece 5 overlap in the stacking direction on the left side of the figure. 【0031】 Thus, if the area where the RFID label 11 is attached to each form piece 5 is limited, the RFID labels 11 will overlap in the stacking direction on the folded continuous form paper 1. In contrast, in this embodiment, the form pieces 5 are composed of two types: a first form piece 5a and a second form piece 5b, each with different RFID labels 11a and 11b attached, thereby preventing damage to the RFID labels 11a and 11b. 【0032】 More specifically, the first RFID label 11a is affixed to the first form paper piece 5a, and the second RFID label 11b is affixed to the second form paper piece 5b. Both the first RFID label 11a and the second RFID label 11b consist of an RFID inlet 12 covered with a protective sheet 13. The RFID inlet 12 and the protective sheet 13 are common and have the same planar shape as shown in Figures 5 and 6. However, in the first RFID label 11a, the RFID inlet 12 is affixed to the center of the protective sheet 13, whereas in the second RFID label 11b, the RFID inlet 12 is shifted to one side of the protective sheet 13 (to the right in Figures 5 and 6). Therefore, in the second RFID label 11b, the IC chip 15 and antenna 16 are positioned shifted to one side compared to the first RFID label 11a. 【0033】 As shown in Figure 7, the first RFID label 11a and the second RFID label 11b are affixed to the label attachment area S of each form piece 5a, 5b in the same orientation. At this time, even though the first RFID label 11a and the second RFID label 11b are affixed in the same orientation and position, their RFID inlets 12 are offset from each other in the left-right direction, so the IC chip 15 and antenna 16 of the second RFID label 11b are positioned to the right of the first RFID label 11a. Furthermore, in this embodiment, the label attachment area S is slightly larger than the RFID labels 11a and 11b, and the RFID labels 11a and 11b can be attached with a slight offset. As shown in Figure 7(A), the first RFID label 11a is attached to the left of the label attachment area S on the first form paper piece 5a, and as shown in Figure 7(B), the second RFID label 11b is attached to the right of the label attachment area S on the second form paper piece 5b. This ensures that the IC chip 15 and antenna 16 of the second RFID label 11b are positioned further to the right than those of the first RFID label 11a. 【0034】 Thus, in the second form piece 5b, the IC chip 15 and antenna 16 are positioned to the right of the first RFID label 11a, and the second RFID label 11b is positioned to the right of the first RFID label 11a on the first form piece 5a. For this reason, in this embodiment, as shown in Figure 8, when the first form piece 5a and the second form piece 5b are stacked in the same orientation, the IC chips 15 of the first form piece 5a and the second form piece 5b are offset in the left-right direction and are configured not to overlap in the stacking direction. 【0035】 As shown in Figures 1 and 2, the first form paper piece 5a and the second form paper piece 5b are arranged in pairs along the longitudinal direction of the continuous form paper 1. That is, in the continuous form paper 1, two pairs of the first form paper piece 5a are arranged consecutively, followed by two pairs of the second form paper piece 5b, and then two pairs of the first form paper piece 5a again, and so on, with two pairs of the first form paper piece 5a and two pairs of the second form paper piece 5b alternating. As described above, in the folded continuous form paper 1, every other form paper piece 5 overlaps in the same orientation, so when two pairs of the first form paper piece 5a and two pairs of the second form paper piece 5b are arranged alternately, as shown in Figures 3 and 9, the first RFID label 11a and the second RFID label 11b will overlap alternately in the stacking direction in the folded continuous form paper 1. 【0036】 In this embodiment, by stacking the first form paper piece 5a and the second form paper piece 5b alternately in the stacking direction with the same orientation, the pressure applied to the IC chip 15 from the stacking direction can be reduced. As described above, even when the first form paper piece 5a and the second form paper piece 5b are stacked in the same orientation, the IC chips 15 of the RFID labels 11a and 11b attached to them do not overlap in the stacking direction. As shown in Figure 10, the protrusions that bulge out at the IC chip 15 placement area 28 of the first RFID label 11a and the protrusions that bulge out at the IC chip 15 placement area 28 of the second RFID label 11b are positioned in a left-right offset position, thus distributing the pressure applied to the IC chip 15 from the stacking direction. 【0037】 Thus, in this embodiment, the area on which the RFID label 11 can be attached to the form paper pieces 5a and 5b is limited. However, by alternately attaching two pieces each of the first form paper piece 5a with the first RFID label 11a attached and the second form paper piece 5b with the second RFID label 11b attached, the number of IC chips 15 overlapping in the stacking direction can be reduced, thereby reducing the load on the IC chips 15. Furthermore, in this embodiment, two types of RFID labels 11a and 11b are attached to the form paper pieces 5a and 5b. However, since the two types of RFID labels 11a and 11b are composed of the same RFID inlet 12 and protective sheet 13, and only one type of RFID inlet 12 and protective sheet 13 is sufficient, this can be achieved without increasing the cost of the RFID labels. Furthermore, since the two types of RFID labels 11a and 11b consist of the same IC chip 15 and antenna 16, there is no variation in the performance of the first form paper piece 5a and the second form paper piece 5b. 【0038】 In particular, in this embodiment, the position of the RFID inlet 12 on the second RFID label 11b is shifted to the right compared to the first RFID label 11a, and the second RFID label 11b is attached shifted to the right compared to the first RFID label 11a. As a result, the synergistic effect of the shift in the RFID inlet 12 and the shift in the label attachment position has the advantage of increasing the amount of displacement of the IC chip 15. 【0039】 Furthermore, as shown in Figure 8, in this embodiment, when the first RFID label 11a of the first form paper piece 5a and the second RFID label 11b of the second form paper piece 5b are stacked in the stacking direction, the respective IC chips 15 are configured so that they do not overlap with the other antenna 16 in the stacking direction. As shown in Figure 6, since the non-arrangement area 26 of each RFID label 11a, 11b is thinner than the arrangement area 27, 29 of the antenna 16, by arranging the IC chips 15 of the first RFID label 11a and the second RFID label 11b so that they do not overlap with the other antenna 16, the thickness of the arrangement area 28 of the IC chip 15 in the folded continuous form paper 1 can be reduced by the thickness of the antenna 16. 【0040】 Furthermore, in this embodiment, as shown in Figures 7 and 8, the IC chip 15 and antenna 16 are positioned to the right of the first form piece 5a on the second form piece 5b. However, the offset of the antenna 16 is smaller than the width of the multiple loop lines 19, and the left and right sides of the multiple loop lines 19 of the first RFID label 11a and the second RFID label 11b, which overlap in the stacking direction, partially overlap in the stacking direction. As a result, the multiple loop lines 19 of each overlap all the way around. As shown in Figure 6, the area 27 where the antenna 16 (multiple loop lines 19) is located is thicker and more raised than the area 26 where the antenna 16 is not located. Therefore, if the areas where the multiple loop lines 19 are located overlap in the stacking direction on the first RFID label 11a and the second RFID label 11b, the area where the multiple loop lines 19 are located becomes relatively thicker on the folded continuous form 1. This makes it easier for pressure to be applied to this area, thereby making it easier to distribute the pressure applied to the area 28 where the IC chip 15 is located. 【0041】 In particular, since the IC chip 15 is formed inside the multiple loop lines 19, if the multiple loop lines 19 of the first RFID label 11a and the second RFID label 11b, which overlap in the stacking direction as in this embodiment, overlap all around, the pressure applied to the IC chip 15 can be distributed in the front, back, left, and right directions, thus uniformly distributing the pressure applied to the IC chip 15 to its surroundings. 【0042】 Furthermore, in this embodiment, as shown in Figure 8, the first RFID label 11a and the second RFID label 11b, which overlap in the stacking direction, are configured such that a portion of the jumper wire 21 of each antenna 16 overlaps with the multi-loop wire 19 of the other antenna 16 in the stacking direction. As described above, the portion 29 where the jumper wire 21 is located is the thickest and most raised portion of the antenna 16 (see Figure 6). Therefore, if the portion 29 where the jumper wire 21 is located overlaps with the portion 27 where the other multi-loop wire 19 is located in the thickness direction, the thickness of that portion in the folded continuous form 1 will be comparable to the thickness of the portion 29 where the IC chip 15 is located. For this reason, in this embodiment, the pressure applied to the portion 28 where the IC chip 15 is located can be largely distributed to the portion 29 where the jumper wire 21 is located. 【0043】 Furthermore, in this embodiment, since the first form paper pieces 5a and the second form paper pieces 5b, which are facing the same direction, are arranged alternately in the stacking direction, the number of first form paper pieces 5a and second form paper pieces 5b that overlap in the stacking direction remains approximately equal regardless of how many form paper pieces 5a and 5b are folded. This has the advantage that pressure is less likely to concentrate on one of the IC chips 15 of the first form paper piece 5a or the second form paper piece 5b. 【0044】 The continuous form paper 1 of this embodiment can be manufactured by forming perforations 4 at the boundary of the form paper pieces 5 on a long strip-shaped paper base material 3 that constitutes the continuous form paper 1, attaching a first RFID label 11a to the label attachment area S of the first form paper piece 5a, and attaching a second RFID label 11b to the label attachment area S of the second form paper piece 5b. To attach the two types of RFID labels 11a and 11b, a strip-shaped release paper with two pieces each of the two types of RFID labels 11a and 11b attached alternately is prepared, and the RFID labels 11a and 11b on the release paper are then attached in order to the label attachment areas S of the form paper pieces 5a and 5b using a label attachment device. Alternatively, a release paper with the first RFID label 11a attached and a release paper with the second RFID label 11b attached may be prepared, and when attaching the first RFID label 11a and when attaching the second RFID label 11b, the label attachment device may peel the RFID labels 11a and 11b from separate release papers and attach them to the form paper pieces 5a and 5b. [Examples] 【0045】 This embodiment is a modified version of the configuration of Embodiment 1. Therefore, components similar to those in Embodiment 1 are denoted by the same reference numerals in the text and figures, and detailed explanations are omitted. Figure 11 is an unfolded view of the continuous form paper 51 of this embodiment. Similar to Embodiment 1 (see Figure 1), the continuous form paper 51 of this embodiment consists of multiple form paper pieces 5 connected in one direction, and is composed of a long strip-shaped paper base material 3 made of high-quality paper or the like. All form paper pieces 5 are rectangular in shape and are continuous in the longitudinal direction of the form paper pieces 5. Perforations 4 are formed at the boundaries of adjacent form paper pieces 5, crossing the paper base material 3 in the width direction, making it easy to bend and separate the paper base material 3 at the boundaries of each form paper piece 5. 【0046】 In the continuous form paper 1 of Example 1, the form paper pieces 5 are folded in an accordion style along all perforations 4 formed at the boundaries of the form paper pieces 5, with each piece being folded on top of the others (see Figure 2). However, in this embodiment, as shown in Figure 12, the form paper pieces 5 are folded in an accordion style along every other perforation 4, with two pieces being folded on top of each other. When the form paper pieces 5 are folded in this way, as shown in Figure 13, every three pieces of form paper will overlap in the same orientation in the stacking direction. Therefore, in this embodiment, the first form paper piece 5a and the second form paper piece 5b are configured to be connected alternately in groups of four along the longitudinal direction of the continuous form paper 51, so that the first RFID label 11a and the second RFID label 11b overlap alternately in the stacking direction on the folded continuous form paper 51. Thus, the present invention can also be applied to continuous form paper in which multiple form paper pieces are folded on top of each other. [Examples] 【0047】 This embodiment is a modification of the configuration of the second RFID label affixed to the second form paper piece 5b compared to Embodiment 1. Therefore, components similar to those in Embodiment 1 are denoted by the same reference numerals in the text and figures, and detailed explanations are omitted. The second RFID label 11c in this embodiment is equipped with an RFID inlet 12a that is different from that of the first RFID label 11a. Hereinafter, in order to distinguish between the two types of RFID inlets 12 and 12a, the RFID inlet 12 of the first RFID label 11a (the same as in Embodiment 1) will be referred to as the "first inlet," and the RFID inlet 12a of the second RFID label 11c will be referred to as the "second inlet." As shown in Figure 14, the IC chip 15 and antenna 16 of the second inlet 12a are positioned closer to one side of the inlet substrate 14 compared to the first inlet 12. Note that the inlet substrate 14, IC chip 15, and antenna 16 are common to both the first inlet 12 and the second inlet 12a. Therefore, in this embodiment, the RFID inlets 12 and 12a are positioned in the same location and orientation on the first RFID label 11a and the second RFID label 11b, but on the second RFID label 11c to which the second inlet 12a is attached, the IC chip 15 and antenna 16 are positioned offset to one side compared to the first RFID label 11a. 【0048】 As described above, in the second RFID label 11b according to Embodiment 1, the IC chip 15 and antenna 16 were offset to one side by attaching the RFID inlet 12 to the side of the protective sheet 13 (see Figures 5 and 6). However, even when the IC chip 15 and antenna 16 are positioned towards one side of the inlet substrate 14, as in this embodiment, the IC chip 15 and antenna 16 can be offset to one side, similar to Embodiment 1, thereby reducing the pressure applied to the IC chip 15 from the stacking direction. In this embodiment, the RFID inlets 12 and 12a are positioned in the same location and orientation in the first RFID label 11a and the second RFID label 11b. However, similar to Embodiment 1, the RFID inlet 12a may be attached to the right side of the protective sheet 13 in the second RFID label 11c. With this configuration, the amount of offset of the IC chip 15 can be increased. [Examples] 【0049】 This embodiment is a modification of the configuration of the second RFID label affixed to the second form paper piece 5b compared to Embodiment 1. Therefore, components similar to those in Embodiment 1 are denoted by the same reference numerals in the text and figures, and detailed explanations are omitted. In this embodiment, the second RFID label 11d has the RFID inlet 12 positioned in the opposite direction to the first RFID label 11a. Specifically, as shown in Figure 15, in this embodiment, the protective sheet 13 is attached to the back side (non-distribution side) of the RFID inlet 12, and the front side (distribution side) of the RFID inlet 12 is attached to the paper substrate 3. Then, as shown in Figure 16, the second RFID label 11d is attached to the label attachment area S of the second form paper piece 5b such that, in a plan view, the placement positions of the IC chip 15 and antenna 16 are symmetrical to those of the first RFID label 11a on the first form paper piece 5a. 【0050】 Thus, in the second RFID label 11b according to Embodiment 1, the IC chip 15 and antenna 16 were offset to one side by attaching the RFID inlet 12 to the side of the protective sheet 13 (see Figures 5 and 6). However, even when the RFID inlet 12 is arranged in the opposite direction, as in this embodiment, the IC chip 15 can be offset from the first RFID label 11a, similar to Embodiment 1, and the pressure applied to the IC chip 15 from the stacking direction can be reduced, similar to Embodiment 1. Furthermore, since the second RFID label 1111d of this embodiment is composed of the same RFID inlet 12 and protective sheet 13 as the first RFID label 11a, it can be implemented without increasing the cost of the RFID label, and there is no variation in the performance of the first form paper piece 5a and the second form paper piece 5b. 【0051】 Furthermore, in this embodiment, as shown in Figure 16(C), the first RFID label 11a and the second RFID label 11d are configured such that the IC chip 15 of each does not overlap with the antenna 16 of the other RFID label 11a, 11d in the stacking direction, and the multi-loop lines 19 of each are configured to overlap in the stacking direction around the entire circumference, and furthermore, a portion of the jumper wire 21 of each antenna 16 is configured to overlap with the multi-loop lines 19 of the other antenna 16 in the stacking direction. Therefore, in this embodiment as well, similar to Embodiment 1, the pressure applied to the IC chip 15 from the stacking direction can be distributed and reduced to the antenna 16 placement area. 【0052】 Although embodiments of the present invention have been described above, the present invention is not limited to the configuration of the above embodiments, and for example, the configuration of the above embodiments can be modified as follows. 【0053】 The shape of the RFID label 11 is not limited to a rectangular shape; various shapes such as circles, ellipses, and regular polygons can be used. In the above embodiment, the IC chip 15 was shifted left to right (in the width direction of the continuous form paper) between the first form paper piece 5a and the second form paper piece 5b, which overlap in the stacking direction. However, the direction in which the IC chip 15 is shifted is not limited to left to right; it can also be in the front-to-back or diagonal directions. In the above embodiment, the direction in which the IC chip 15 is shifted on the second RFID label 11b (to the right) coincides with the direction in which the second RFID label 11b is attached, shifted from the first RFID label 11a. However, even if the direction in which the attachment position of the second RFID label 11b is shifted does not coincide with the direction in which the IC chip 15 is shifted, the amount of shift of the IC chip 15 can be increased as long as it intersects the direction in which the IC chip 15 is shifted at an acute angle. 【0054】 Furthermore, in the above embodiment, the form paper piece 5 is composed of two types: a first form paper piece 5a and a second form paper piece 5b. However, in addition to the first and second form paper pieces, a third and a fourth form paper piece may also be provided. Specifically, by attaching third and fourth RFID labels to the third and fourth form paper pieces, in which the IC chips 15 are offset in a direction different from that of the second RFID label 11b, the number of IC chips 15 overlapping in the stacking direction can be reduced to half of that in the above embodiment. 【0055】 Furthermore, in the above embodiment, the first form paper piece 5a and the second form paper piece 5b are configured to be arranged alternately in the same orientation in the stacking direction. However, in the present invention, it is sufficient that the form paper pieces 5 that overlap in the same orientation in the stacking direction include the first form paper piece 5a and the second form paper piece 5b, and the first form paper piece 5a and the second form paper piece 5b do not need to be arranged alternately. 【0056】 Furthermore, although the RFID label 11 in the above embodiment 1 is an RFID inlet 12 covered with a protective sheet 13, the protective sheet 13 may be omitted, and the RFID label 11 may be composed of only the RFID inlet 12. Also, the protective sheet 13 may be the same size as the RFID inlet 12, or it may be smaller than the RFID inlet 12. 【0057】 Furthermore, while the multi-loop wire 19 in the above embodiment is a substantially rectangular annular loop wound five times, the multi-loop wire according to the present invention may have a shape other than a rectangular annular, such as a circular loop, and the number of windings can also be changed as appropriate.
