Description

[Technical Field]

[0001] The present invention relates to a continuous form sheet that is made up of a plurality of continuous form sheets to which RFID labels are affixed. [Background technology]

[0002] A continuous form paper formed by folding continuous form paper segments in one direction so that they overlap in an accordion-like manner is generally called fanfold paper. A type of such continuous form paper with an RFID label affixed to each segment is known. Because the location of the IC chip included in the RFID label on each segment of such continuous form paper is convex, when the continuous form paper is folded, pressure from the stacking direction tends to concentrate on the location of the IC chip, resulting in the problem of the IC chip being easily damaged. To solve this problem, it has been proposed to offset the affixing positions of the RFID labels on multiple overlapping segments in the same stacking direction, front to back, left to right, and thereby reduce the number of overlapping IC chips in the stacking direction, thereby preventing localized thickening of the IC chip location when the continuous form paper is folded (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6475470 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional continuous form paper, the range in which an RFID label can be attached to each piece of form paper may be limited due to specification constraints. In such cases, with the configuration described in Patent Document 1, it becomes difficult to shift the attachment positions of the RFID labels so that the IC chips on overlapping pieces of form paper that are facing the same direction do not overlap in the stacking direction. Furthermore, even if the RFID labels can be attached so that the IC chips do not overlap, if the IC chips are not spaced apart sufficiently, the protrusions at the locations where the IC chips are located may interfere with each other, and the pressure applied to the IC chips in the stacking direction when the paper is folded may not be sufficiently reduced.

[0005] The present invention was made in consideration 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 in a continuous form in which a piece of form paper with an RFID tag attached is folded accordion-like, even when the area on the piece of form paper where the RFID label can be attached is limited. [Means for solving the problem]

[0006] The present invention relates to a continuous form paper comprising a plurality of form paper pieces continuing in one direction, the form paper pieces being folded one by one or a plurality of pieces at a time by folding back in an accordion-like manner at the boundaries of the form paper pieces, and an RFID label having an antenna and an IC chip connected to the antenna is affixed to one side of each of the form paper pieces, and the plurality of form paper pieces overlapping in the same direction 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 have the same RFID label. The continuous form paper is characterized in that the second RFID label has the antenna and the IC chip, and has the same planar shape, the antenna and the IC chip of the second RFID label are positioned offset in a predetermined direction from the first RFID label, the first group of form paper pieces and the second group of form paper pieces are overlapped in the same direction in the stacking direction, and 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 positioned so that they do not overlap in the stacking direction. Here, the "stacking direction" of the 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 slips can be shifted without having to shift the affixing positions of the RFID labels on the first and second groups of form slips back and forth or left and right, so that the IC chips on the first and second groups of form slips can be prevented from overlapping in the stacking direction when the form continuous paper is folded. Therefore, according to the present invention, even with a form continuous paper in which the range in which RFID labels can be affixed to the form slips is limited, it is possible to reduce the number of IC chips that overlap in the stacking direction when the form continuous paper is folded, and thereby reduce the pressure applied to the IC chips. Furthermore, since the present invention uses the same antenna and IC chip for the first RFID label and the second RFID label, it can be realized at a relatively low cost, and there is no variation in performance between the first group of form paper sheets and the second group of form paper sheets.

[0008] In a specific embodiment of the present invention, the RFID label includes an RFID inlet having the antenna and the IC chip connected to the antenna disposed on one side of an inlet substrate, and the second RFID label has the same RFID inlet as the first RFID label but shifted in the predetermined direction from the first RFID label. In this configuration, the first and second RFID labels use the same RFID inlet, thereby reducing the cost of the RFID labels.

[0009] In another specific embodiment of the present invention, the RFID label includes an RFID inlet having the antenna and the IC chip connected to the antenna disposed on one side of an inlet substrate, the RFID inlet of the first RFID label and the RFID inlet of the second RFID label having the same planar shape of the inlet substrate, and the antenna and IC chip of the RFID inlet of the second RFID label being shifted in the predetermined direction relative to the inlet substrate compared to the RFID inlet of the first RFID label. Even with this configuration, the first RFID label and the second RFID label use the same antenna and IC chip, so the present invention can be realized at relatively low cost.

[0010] In the present invention, a configuration is proposed in which the second RFID labels of the second group of form-paper pieces are affixed offset in a specific direction intersecting the predetermined direction at an acute angle with respect to the first RFID labels of the first group of form-paper pieces. Even if the range in which RFID labels can be affixed to the form-paper pieces is limited, if it is possible to shift the affixing positions slightly, by shifting the affixing positions of the second group of RFID labels as in this configuration, it is possible to increase the offset between the IC chips of the first group of form-paper pieces and the second group of form-paper pieces that overlap in the stacking direction.

[0011] Another aspect of the present invention is a continuous form comprising a plurality of continuous form pieces in one direction, the form pieces being folded one by one or multiple by folding back at the boundaries of the form pieces in an accordion-like manner, and one side of each of the form pieces has an RFID label affixed to one side of an inlet substrate, the RFID label including an RFID inlet having an antenna and an IC chip connected to the antenna, and the plurality of form pieces overlapping in the same direction in the stacking direction are a first group of form pieces to which a first RFID label has been affixed and a second group of form pieces to which a second RFID label has been affixed. and a continuous form paper sheet, 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 sheets and the second group of form paper sheets, which are overlapped in the same direction in the stacking direction, are arranged such that 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.

[0012] Even with this configuration, the positions of the IC chips on the first and second groups of form slips can be shifted without having to shift the affixing positions of the RFID labels on the first and second groups of form slips back and forth or left and right, so it is possible to prevent the IC chips on the first and second groups of form slips from overlapping in the stacking direction when the form continuous paper is folded. Therefore, according to the present invention, even with a form continuous paper in which the range in which RFID labels can be affixed to the form slips is limited, it is possible to reduce the number of IC chips that overlap in the stacking direction when the form continuous paper is folded, and thereby reduce the pressure applied to the IC chips. Furthermore, in this configuration, the same RFID inlet is used for the first RFID label and the second RFID label, so it can be realized at a relatively low cost, and there is no variation in performance between the first group of form paper sheets and the second group of form paper sheets.

[0013] In the present invention, it is proposed that the first group of form paper pieces and the second group of form paper pieces, which are stacked in the same direction in the stacking direction, are arranged so that the IC chips of each do not overlap with the antennas of the form paper pieces of the other group in the stacking direction, and that at least a portion of the antennas of each do overlap with the antennas of the form paper pieces of the other group in the stacking direction.

[0014] On each piece of form paper, the area where the antenna of the RFID label is located is also raised and thick, although not as thick as the area where the IC chip is located. Therefore, if the IC chip is arranged 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 area where the IC chip is located in the folded continuous form paper can be reduced by the thickness of the antenna of the other group. On the other hand, if the antennas of the first and second groups of form paper pieces are arranged so that they overlap in the stacking direction, the thickness of that area in the folded continuous form paper will be relatively large, making it easier for pressure to be applied to that area from the stacking direction, and making it possible to distribute the pressure applied to the area where the IC chip is located.

[0015] Furthermore, in the above configuration, it is proposed that the antenna is a multiple loop antenna, and that a jumper wire for the antenna is 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] The jumper wire is formed so as to straddle the inside and outside of the multiple loop antenna, and generally, the area where the jumper wire is located is the thickest in the multiple loop antenna of an RFID label. Therefore, if the jumper wire is located in the area where the antennas of the first and second groups of form paper pieces overlap, as in this configuration, pressure from the stacking direction can be more easily applied to the area where the antennas overlap, making it possible to further reduce the pressure applied to the area where the IC chip is located.

[0017] In addition, in the present invention, it is proposed that the antenna is a multiple loop antenna, the IC chip is arranged inside the multiple loop wire of the antenna, and the multiple loop wire of the first group of form paper pieces and the multiple loop wire of the second group of form paper pieces are arranged so as to overlap in the stacking direction around the entire circumference of the multiple loop wire.

[0018] In this configuration, when the continuous form paper is folded, the multiple loop antennas of the first and second groups of form pieces, which are overlapped in the same direction, overlap in the stacking direction around the location of the IC chip, thereby forming a relatively thick annular portion that surrounds the location of the IC chip, making it possible to uniformly distribute the pressure applied to the IC chip from the stacking direction around the IC chip. Note that the overlapping of the multiple loop wires is not limited to each individual wire that makes up the multiple loop wire overlapping, and it is sufficient that at least a portion of the bundle of wires that makes up the multiple loop wire overlaps around the entire circumference. [Effects of the Invention]

[0019] As described above, according to the present invention, when a piece of paper is folded accordion-like and stacked in the same direction in the stacking direction, the position of the IC chip of the RFID label can be shifted without having to shift the RFID label back and forth or left and right to attach it to the piece of paper.Therefore, even if the area in which the RFID label can be attached to the piece of paper is limited, the pressure received by the IC chip of the RFID label can be suitably reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The embodiments of the present invention will be described with reference to the following examples. In the following examples, the first form piece 5a corresponds to the first group of form pieces according to the present invention, the second form piece 5b corresponds to the second group of form pieces according to the present invention, 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. In the following examples, the direction along the longitudinal direction of the continuous form paper (the direction in which the form pieces continue) will be described as the front-to-rear direction of the form pieces, and the direction along the short side (width direction) of the continuous form paper will be described as the left-to-right direction of the form pieces. However, the present invention is not limited to these defined directions. [Example]

[0022] As shown in Figure 1, the continuous form paper 1 of this embodiment is made up of multiple continuous form paper segments 5 arranged in one direction. All of the form paper segments 5 are rectangular and of the same size, and are arranged in the same direction along the length of the continuous form paper 1. The continuous form paper 1 is made up of a long, strip-shaped paper base 3 made of high-quality paper or the like. At the boundaries between adjacent form paper segments 5 along the surface of the paper base 3, perforations 4 are formed that run across the paper base 3 in the width direction, making it easy to bend and separate the paper base 3 at the boundaries between each form paper segment 5.

[0023] The form continuous paper 1 is fanfold paper, and as shown in Figure 2, it is folded back in an accordion-like shape by alternately making mountain and valley folds at each perforation 4 formed at the boundary of the form segments 5, so that the form segments 5 are folded one on top of the other as shown in Figure 3, and then transported and stored. When issuing a form using the form continuous paper 1 of this embodiment, the required information is printed on one or both sides of each form segment 5 using a printer or the like, and the printed form segments 5 are separated at the perforations 4 and used as a form. The basic configuration of this form continuous paper 1 can be a known one, so a detailed description thereof will be omitted.

[0024] As shown in Fig. 1, one substantially rectangular RFID label 11 is attached to one side of each document piece 5 in a predetermined label attachment section S. As shown in Figs. 4 to 6, the RFID label 11 is composed of an RFID inlet 12 and a protective sheet 13 that covers the RFID inlet 12. Note that the RFID labels 11 attached to the document piece 5 are of two types, a first RFID label 11a and a second RFID label 11b, as shown in Figs. 5 and 6, but both have the same basic configuration.

[0025] The RFID inlet 12 is a non-contact, battery-less type that can send and receive signals such as commands and data contactlessly between itself and an input / output device (reader / writer device, not shown) using HF-band electromagnetic waves. As shown in Fig. 4, the RFID inlet 12 has an antenna 16 and an IC chip 15 disposed on the front side (the mounting surface) of a thin-film inlet substrate 14. The inlet substrate 14 is made of a substantially rectangular PET film, and as shown in Fig. 6, an adhesive 23 is applied to the back side of the inlet substrate 14 for attaching it to a paper substrate 3.

[0026] 4 to 6, antenna 16 is a multiple loop antenna formed by winding a conductive wire multiple times into a loop, and is printed on the surface of inlet substrate 14 with a conductive paste. Antenna 16 is composed of multiple loop wire 19 formed by winding a substantially rectangular annular loop five times, a pair of terminal wires 20 extending inside multiple loop wire 19, and a jumper wire 21 that straddles multiple loop wire 19 and electrically connects the outer end of multiple loop wire 19 to one of terminal wires 20. IC chip 15 is capable of electromagnetically storing required information, and is placed on terminal wire 20. It is electrically connected to antenna 16 by being bonded to terminal wire 20 with anisotropic conductive adhesive 17.

[0027] 4 to 6, the protective sheet 13 has a generally rectangular shape in plan view. The protective sheet 13 may be made of a PET film or paper, and has an adhesive 24 of a substantially uniform thickness applied to its backside. The protective sheet 13 is larger in length and width than the planar shape of the RFID inlet 12, and is attached via the adhesive 24 on its backside so as to cover the entire front side (the installation surface side) of the RFID inlet 12, and is also attached to the paper base material 3 around the RFID inlet 12.

[0028] As described above, the RFID label 11 according to this embodiment is configured such that the surface of the RFID inlet 12 is covered with the protective sheet 13. However, as shown in FIG. 4, the surface of the RFID inlet 12 is not flat, and undulations due to the IC chip 15 and the antenna 16 are present. Therefore, as shown in FIG. 6, the surface of the RFID label 11 has irregularities following the shapes of the IC chip 15 and the antenna 16. Specifically, as shown in FIG. 6, the RFID label 11 has the thinnest portion at the outer periphery 25 where the protective sheet 13 is attached to the paper substrate 3. In contrast, a portion 26 of the inlet substrate 14 where the IC chip 15 and the antenna 16 are not provided is raised thicker than the outer periphery 25 by the thickness of the inlet substrate 14. Furthermore, portions 27 and 29 where the antenna 16 is provided are raised higher than the outer periphery 25 by the thickness of the inlet substrate 14 and the antenna 16. Furthermore, the mounting area 28 for the IC chip 15 is raised 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 generally formed with a substantially constant thickness, but the jumper wire 21 is formed so as to straddle the multiple loop wire 19, so the mounting area 29 for the jumper wire 21 is raised thicker than the mounting areas 27 for the multiple loop wire 19 and the terminal wire 20. Thus, the surface of the RFID label 11 according to this embodiment is formed with irregularities following the shapes of the IC chip 15 and the antenna 16, and among these, the mounting area 28 for the IC chip 15 is raised in a large convex shape. For ease of explanation, the thickness of the RFID label 11 is illustrated in FIGS. 4 and 6 as being thicker than it actually is, 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 fit into a predetermined label attachment section S of each document piece 5 using adhesives 23, 24 applied to the RFID inlet 12 and the protective sheet 13. The label attachment section S is a rectangular area that is slightly larger than the planar shape of the RFID label 11, and is provided in the same position on all document pieces 5. Specifically, as shown in Figure 1, the label attachment section S is provided on one side of one face of each document piece 5 in the longitudinal direction, in the center in the lateral direction.

[0030] 3, in the continuous form paper 1 folded accordion-like, adjacent form pieces 5 overlap with their fronts facing backwards across the perforations 4, and every other form piece 5 overlaps with its back facing the same in the stacking direction. Therefore, in the folded continuous form paper 1, the label attachment portions S of adjacent form pieces 5 do not overlap, but the label attachment portions S of the RFID labels 11 of every other form piece 5 overlap. As described above, the size of the label attachment portion S is limited, and the attachment positions of the RFID labels 11 cannot be shifted significantly, so the RFID labels 11 affixed to every other form piece 5 overlap in the stacking direction. Specifically, in the continuous form paper 1 in Figure 3, odd-numbered form pieces 5 from the bottom are stacked in the same direction with the RFID label 11 affixed sides facing up, and the RFID labels 11 affixed to each form piece 5 are stacked in the stacking direction on the right side of the figure. In contrast, in Figure 3, even-numbered form pieces 5 from the bottom are stacked in the same direction with the RFID label 11 affixed sides facing down, and the RFID labels 11 affixed to each form piece 5 are stacked in the stacking direction on the left side of the figure.

[0031] In this way, when the location where the RFID label 11 is affixed to each form piece 5 is limited, the RFID labels 11 will overlap in the stacking direction in the folded continuous form 1. In contrast, in this embodiment, the form piece 5 is made up of two types of form piece 5, a first form piece 5a and a second form piece 5b, to which different RFID labels 11a and 11b are affixed, thereby preventing damage to the RFID labels 11a and 11b.

[0032] More specifically, a first RFID label 11a is affixed to the first slip 5a, and a second RFID label 11b is affixed to the second slip 5b. Both the first RFID label 11a and the second RFID label 11b have 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 FIGS. 5 and 6. However, while the RFID inlet 12 is affixed to the center of the protective sheet 13 in the first RFID label 11a, the RFID inlet 12 in the second RFID label 11b is affixed shifted to one side of the protective sheet 13 (to the right in FIGS. 5 and 6). Therefore, the IC chip 15 and the antenna 16 in the second RFID label 11b are positioned shifted to one side compared to the first RFID label 11a.

[0033] 7, the first RFID label 11a and the second RFID label 11b are attached in the same orientation to the label attachment section S of each document piece 5a, 5b. At this time, even if the first RFID label 11a and the second RFID label 11b are attached in the same orientation and at the same position, the RFID inlets 12 of the two labels are positioned 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. In addition, 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.Therefore, as shown in Figure 7(A), the first RFID label 11a is attached to the left of the label attachment area S of the first form 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 of the second form piece 5b, so that the IC chip 15 and antenna 16 of the second RFID label 11b are positioned further to the right than the first RFID label 11a.

[0034] In this way, the second RFID label 11b, in which the IC chip 15 and antenna 16 are arranged more to the right than the first RFID label 11a, is arranged more to the right than the first RFID label 11a of the first form piece 5a. Therefore, 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 direction, the IC chips 15 of the first form piece 5a and the second form piece 5b are misaligned in the left-right direction and are configured so as not to overlap in the stacking direction.

[0035] 1 and 2, the first form fragments 5a and the second form fragments 5b are arranged in pairs in the longitudinal direction of the form web 1. That is, in the form web 1, two consecutive first form fragments 5a are followed by two consecutive second form fragments 5b, and then two consecutive first form fragments 5a are again arranged in a row, and so on, with the first form fragments 5a and the second form fragments 5b arranged in alternating pairs. As described above, in the folded form web 1, every other form fragment 5 faces the same direction, so if the first form fragments 5a and the second form fragments 5b are arranged in alternating pairs, then the first RFID labels 11a and the second RFID labels 11b will be arranged alternately in the stacking direction in the folded form web 1, as shown in FIGS.

[0036] In this embodiment, by stacking the first form pieces 5a and the second form pieces 5b alternately in the stacking direction in the same orientation, it is possible to reduce the pressure applied to the IC chip 15 in the stacking direction. As described above, even when the first form pieces 5a and the second form pieces 5b are stacked in the same orientation, the IC chips 15 of the RFID labels 11a and 11b attached to each of the first and second form pieces 5a and 5b do not overlap in the stacking direction, and as shown in Figure 10, the protrusion that bulges out at the location 28 for the IC chip 15 of the first RFID label 11a and the protrusion that bulges out at the location 28 for the IC chip 15 of the second RFID label 11b are positioned at positions offset in the left-right direction, so that the pressure applied to the IC chip 15 in the stacking direction can be dispersed.

[0037] In this way, in this embodiment, the range in which the RFID labels 11 can be attached to the form pieces 5a, 5b is limited, but by alternately attaching pairs of first form pieces 5a with the first RFID label 11a attached and second form pieces 5b with the second RFID label 11b attached, it is possible to reduce the number of IC chips 15 stacked in the stacking direction and thereby reduce the load on the IC chips 15. Also, in this embodiment, two types of RFID labels 11a, 11b are attached to the form pieces 5a, 5b, but the two types of RFID labels 11a, 11b are configured with the same RFID inlet 12 and protective sheet 13, and only one type of RFID inlet 12 and one type of protective sheet 13 are required, which can be achieved without increasing the cost of the RFID labels. Furthermore, since the two types of RFID labels 11a and 11b are made up of the same IC chip 15 and antenna 16, there is no variation in the performance of the form between the first form piece 5a and the second form piece 5b.

[0038] In particular, in this embodiment, the position of the RFID inlet 12 in the second RFID label 11b is shifted to the right of the first RFID label 11a, and the second RFID label 11b is attached shifted to the right of the first RFID label 11a, which has the advantage of increasing the amount of shift in the IC chip 15 due to the synergistic effect of the shift in the RFID inlet 12 and the shift in the label attachment position.

[0039] 8, in this embodiment, when the first RFID label 11a of the first form piece 5a and the second RFID label 11b of the second form piece 5b are stacked in the stacking direction, the IC chip 15 of each is configured not to overlap the other's antenna 16 in the stacking direction. As shown in Fig. 6, in each of the RFID labels 11a, 11b, the non-antenna 16 area 26 is thinner than the antenna 16 areas 27, 29. Therefore, by arranging the IC chips 15 of the first RFID label 11a and the second RFID label 11b so that they do not overlap the other's antenna 16, the thickness of the IC chip 15 area 28 in the folded form continuous paper 1 can be reduced by the thickness of the antenna 16.

[0040] In addition, in this embodiment, as shown in Figures 7 and 8, the IC chip 15 and antenna 16 are positioned on the second form piece 5b, shifted to the right compared to the first form piece 5a, but the shift in the positioning of the antenna 16 is smaller than the width of the multiple loop line 19, and in the first RFID label 11a and the second RFID label 11b, which overlap in the stacking direction, the left and right sides of each multiple loop line 19 partially overlap in the stacking direction, and as a result, each multiple loop line 19 overlaps around the entire circumference. As shown in Figure 6, the installation area 27 of the antenna 16 (multiple loop wire 19) is thicker and raised than the non-installation area 26 of the antenna 16. Therefore, if the installation areas of the multiple loop wire 19 of the first RFID label 11a and the second RFID label 11b are overlapped in the stacking direction in this manner, the thickness of the installation area of ​​the multiple loop wire 19 in the folded continuous form 1 will be relatively thick, making it easier for pressure to be applied to that area, and making it easier to distribute the pressure applied to the installation area 28 of the IC chip 15.

[0041] In particular, since the IC chip 15 is formed inside the multiple loop wire 19, if the multiple loop wires 19 of the first RFID label 11a and the second RFID label 11b, which are stacked in the stacking direction as in this embodiment, overlap each other all around, the pressure applied to the IC chip 15 can be distributed in all directions, front to back and left to right, and the pressure applied to the IC chip 15 can be distributed evenly around it.

[0042] 8, the first RFID label 11a and the second RFID label 11b, which are stacked in the stacking direction, are configured so that a portion of the jumper wire 21 of each antenna 16 overlaps the multiple loop wire 19 of the other antenna 16 in the stacking direction. As described above, the installation area 29 of the jumper wire 21 is the thickest of all the installation areas of the antenna 16 (see FIG. 6). Therefore, if the installation area 29 of the jumper wire 21 is overlapped in the thickness direction by the installation area 27 of the other multiple loop wire 19, the thickness of this area in the folded continuous form 1 will be comparable to the thickness of the installation area 29 of the IC chip 15. Therefore, in this embodiment, the pressure applied to the installation area 28 of the IC chip 15 can be largely dispersed to the installation area 29 of the jumper wire 21.

[0043] In addition, in this embodiment, the first form paper pieces 5a and second form paper pieces 5b, which are oriented in the same direction, are arranged alternately in the stacking direction, so no matter how many form paper pieces 5a and 5b are folded, the number of first form paper pieces 5a and second form paper pieces 5b overlapping in the stacking direction remains approximately equal, which has the advantage that pressure is less likely to concentrate on the IC chip 15 of one of the first form paper pieces 5a and second form paper pieces 5b.

[0044] The continuous form paper 1 of this embodiment can be manufactured by forming perforations 4 at the boundaries between form pieces 5 in a long strip of paper base material 3 that makes up the continuous form paper 1, affixing a first RFID label 11a to the label affixing area S of the first form piece 5a, and affixing a second RFID label 11b to the label affixing area S of the second form piece 5b. The two types of RFID labels 11a, 11b can be affixed by preparing a strip of release paper with two pieces of the two types of RFID labels 11a, 11b affixed alternately, and then affixing the RFID labels 11a, 11b on the release paper to the label affixing areas S of the form pieces 5a, 5b in order using a label affixing device. Alternatively, a release paper with the first RFID label 11a and a release paper with the second RFID label 11b may be prepared, and when attaching the first RFID label 11a and the second RFID label 11b, the label attachment device may peel the RFID labels 11a and 11b from the separate release papers and attach them to the slips of paper 5a and 5b. [Example]

[0045] This embodiment is a partial modification of the configuration of embodiment 1. Therefore, the same components as those in embodiment 1 are denoted by the same reference numerals in the text and drawings, and detailed description thereof will be omitted. Figure 11 is a development view of the continuous form paper 51 of this embodiment. As with Example 1 (see Figure 1), the continuous form paper 51 of this embodiment is made up of multiple continuous form paper pieces 5 in one direction, and is composed of a long, strip-shaped paper base material 3 made of high-quality paper or the like. All of the form paper pieces 5 are rectangular and of the same size, and are continuous in the longitudinal direction of the form paper pieces 5. At the boundaries between adjacent form paper pieces 5, perforations 4 are formed that traverse the paper base material 3 in the width direction, making it easy to bend and separate the paper base material 3 at the boundaries between each form paper piece 5.

[0046] In the form continuous paper 1 of Example 1, the form pieces 5 are folded one by one using accordion folds at all perforations 4 formed at the boundaries of the form pieces 5 (see FIG. 2). However, in this example, as shown in FIG. 12, the form pieces 5 are folded two by two using accordion folds at every other perforation 4. When the form pieces 5 are folded two by two in this manner, every third form piece 5 overlaps in the same direction in the stacking direction, as shown in FIG. 13. Therefore, in this example, the first form piece 5a and the second form piece 5b are configured to be alternately connected in groups of four in the longitudinal direction of the form continuous paper 51, so that the first RFID label 11a and the second RFID label 11b overlap alternately in the stacking direction in the folded form continuous paper 51. In this way, the present invention can also be applied to form continuous paper in which form pieces are folded multiple by multiple. [Example]

[0047] In this embodiment, the configuration of the second RFID label affixed to the second document piece 5b is partially changed from that of embodiment 1. Therefore, the same components as those in embodiment 1 are denoted by the same reference numerals in the text and drawings, and detailed description thereof will be omitted. The second RFID label 11c according to this embodiment is provided with an RFID inlet 12a different from that of the first RFID label 11a. Hereinafter, to distinguish between the two types of RFID inlets 12, 12a, the RFID inlet 12 (the same as in the first embodiment) of the first RFID label 11a 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 FIG. 14 , the second inlet 12a has an IC chip 15 and an antenna 16 located closer to one side of the inlet substrate 14 than the first inlet 12. The inlet substrate 14, IC chip 15, and antenna 16 are common to the first inlet 12 and the second inlet 12a. For this reason, in this embodiment, the RFID inlets 12, 12a are arranged in the same position and in the same 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 the antenna 16 are arranged shifted to one side compared to the first RFID label 11a.

[0048] As described above, in the second RFID label 11b according to the first embodiment, the RFID inlet 12 is attached to one side of the protective sheet 13 (see FIGS. 5 and 6 ), so that the IC chip 15 and the antenna 16 are arranged offset to one side. However, even when the IC chip 15 and the antenna 16 are arranged to one side of the inlet substrate 14 as in the present embodiment, the IC chip 15 and the antenna 16 can be arranged offset to one side, as in the first embodiment, thereby reducing the pressure applied to the IC chip 15 in the stacking direction. Note that in the present embodiment, the RFID inlets 12, 12a are arranged in the same position and facing the same direction in the first RFID label 11a and the second RFID label 11b. However, in the second RFID label 11c, the RFID inlet 12a may be attached to the right side of the protective sheet 13 as in the first embodiment. This configuration increases the offset of the IC chip 15. [Example]

[0049] In this embodiment, the configuration of the second RFID label affixed to the second document piece 5b is partially changed from that of embodiment 1. Therefore, the same components as those in embodiment 1 are denoted by the same reference numerals in the text and drawings, and detailed description thereof will be omitted. The second RFID label 11d according to this embodiment has an RFID inlet 12 arranged in a reversed orientation to that of the first RFID label 11a. Specifically, as shown in Fig. 15, the second RFID label 11d according to this embodiment has a protective sheet 13 attached to it so as to cover the back side (non-mounted side) of the RFID inlet 12, and the front side (mounted side) of the RFID inlet 12 attached to the paper base material 3. Then, as shown in Fig. 16, the second RFID label 11d is attached to the label attachment portion S of the second form-piece 5b so that the positions of the IC chip 15 and the antenna 16 are symmetrical to those of the first RFID label 11a on the first form-piece 5a in a plan view.

[0050] As described above, in the second RFID label 11b according to Example 1, the RFID inlet 12 was attached toward one side of the protective sheet 13 (see FIGS. 5 and 6), so that the IC chip 15 and the antenna 16 were arranged offset toward one side, but even when the RFID inlet 12 is arranged upside down as in this example, the IC chip 15 can be arranged offset from the first RFID label 11a, as in Example 1, and pressure applied to the IC chip 15 in the stacking direction can be reduced, as in Example 1. Furthermore, the second RFID label 1111d of this example is composed of the same RFID inlet 12 and protective sheet 13 as the first RFID label 11a, so it can be realized without increasing the cost of the RFID label, and there is no variation in the performance of the form between the first form piece 5a and the second form piece 5b.

[0051] 16(C), in this embodiment, the first RFID label 11a and the second RFID label 11d are configured so that the IC chip 15 of each does not overlap the antenna 16 of the other RFID label 11a, 11d in the stacking direction, and the multiple loop wires 19 of each overlap over the entire circumference in the stacking direction, and further, a portion of the jumper wire 21 of each antenna 16 overlaps the multiple loop wire 19 of the other antenna 16 in the stacking direction. Therefore, in this embodiment as well, as in embodiment 1, the pressure applied to the IC chip 15 from the stacking direction can be distributed to the location where the antenna 16 is disposed and reduced.

[0052] Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of the above embodiments, and for example, the configurations of the above embodiments can be modified as follows.

[0053] The shape of the RFID label 11 is not limited to a rectangle, and various shapes such as a circle, an ellipse, or a regular polygon can be used. In the above embodiment, the IC chips 15 are shifted left and right (in the width direction of the continuous form) between the first form piece 5a and the second form piece 5b that are stacked in the stacking direction. However, the shift direction of the IC chips 15 is not limited to the left and right direction, and may be forward, backward, or diagonally. In the above embodiment, the direction (to the right) in which the IC chip 15 is shifted in the second RFID label 11b is aligned with the direction in which the second RFID label 11b is attached offset relative to the first RFID label 11a. However, the shift direction of the attachment position of the second RFID label 11b does not need to be aligned with the shift direction of the IC chip 15; as long as it intersects the shift direction at an acute angle with the shift direction, the shift amount of the IC chip 15 can be increased.

[0054] In the above embodiment, the form slip 5 is composed of two types, the first form slip 5a and the second form slip 5b, but third and fourth form slips may be provided in addition to the first and second form slips. Specifically, if third and fourth RFID labels having IC chips 15 shifted in a different direction from the second RFID label 11b are attached to the third and fourth form slips, the number of IC chips 15 stacked in the stacking direction can be reduced to half of that in the above embodiment.

[0055] In addition, 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 direction in the stacking direction, but in the present invention, it is sufficient that the form paper pieces 5 that are overlapped in the same direction 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 have to be arranged alternately.

[0056] Furthermore, although the RFID label 11 of the first embodiment has the RFID inlet 12 covered with the protective sheet 13, the protective sheet 13 may be omitted and the RFID label 11 may be configured only with the RFID inlet 12. The protective sheet 13 may be the same size as the RFID inlet 12, or may be smaller than the RFID inlet 12.

[0057] Furthermore, although the multiple loop wire 19 in the above embodiment is formed by winding five loops of an approximately rectangular annular shape, the multiple loop wire of the present invention may have a shape other than a rectangular annular shape, such as a circular annular shape, and the number of windings can also be changed as appropriate.
