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 is a continuous form paper comprising a plurality of continuous form pieces in one direction, the form pieces being folded one by one or multiple by folding back accordion-like at the boundaries between the form pieces, wherein an RFID label having an antenna and an IC chip connected to the antenna is affixed to one side of each of the form pieces, and the plurality of form pieces stacked in the same orientation in the stacking direction include a first group of form pieces to which the RFID label is affixed in a first orientation, and a second group of form pieces to which the same RFID label as that of the first group of form pieces is affixed in a second orientation rotated a predetermined angle from the first orientation, and the RFID labels of the first group of form pieces and the RFID labels of the second group of form pieces overlap partially or completely in the stacking direction, and the IC chips are arranged 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 affixes RFID labels of the same configuration to the first group of form paper pieces and the second group of form paper pieces, it can be realized without increasing the cost of the RFID labels, and there is no variation in performance between the first group of form paper pieces and the second group of form paper pieces.

[0008] The planar shape of the RFID label of the present invention can be a substantially rectangular, a substantially square, a substantially elliptical, or a substantially circular shape. When the planar shape of the RFID label is a substantially rectangular or a substantially elliptical shape, the IC chip can be positioned off-center on the RFID label and the second orientation can be rotated 180° from the first orientation, allowing the RFID labels of the first and second groups of paper slips to be affixed so that most of the RFID labels overlap in the stacking direction, while the IC chips do not overlap in the stacking direction. Furthermore, when the planar shape of the RFID label is a substantially square or a substantially circular shape, even when the second orientation is rotated 90° or 270° from the first orientation, allowing the RFID labels of the first and second groups of paper slips to be affixed so that most of the RFID labels overlap in the stacking direction, while the IC chips do not overlap in the stacking direction.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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]

[0015] 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.

[0017] 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 piece according to the present invention, and the second form piece 5b corresponds to the second group of form piece 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]

[0018] 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.

[0019] 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.

[0020] As shown in FIG. 1, one substantially rectangular RFID label 11 is attached to a predetermined label attachment section S on one side of each document piece 5. 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. The RFID inlet 12 is a non-contact, battery-less type that can send and receive signals such as commands and data contactlessly between it and an input / output device (reader / writer device) (not shown) using HF-band electromagnetic waves. The RFID inlet 12 has an antenna 16 and an IC chip 15 disposed on the front side (mounting surface) of a thin-film inlet substrate 14. The inlet substrate 14 is made of a substantially rectangular PET film, and an adhesive 23 is applied to the back side of the inlet substrate 14 for attaching it to the paper substrate 3.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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 of ​​the same size as 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.

[0025] 3, in the continuous form paper 1 folded accordion-like, adjacent form pieces 5 overlap with their front and backs facing in opposite directions via the perforations 4, and every other form piece 5 overlaps with its front and 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 label attachment portion S is the same size as the RFID label 11, and the RFID label 11 cannot be attached by shifting it front to back or left to right, 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.

[0026] 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 form continuous paper 1. In contrast, in this embodiment, the form piece 5 is composed of two types of RFID labels 11, a first form piece 5a and a second form piece 5b, with RFID labels 11 affixed at different angles, thereby preventing damage to the RFID labels 11. Specifically, the RFID label 11 is affixed to the first form piece 5a in the orientation shown in FIG. 7(A), whereas the RFID label 11 identical to the first form piece 5a is affixed to the second form piece 5b in an orientation rotated 180° along the paper surface from the orientation shown in FIG. 7(A), as shown in FIG. 7(B). The RFID label 11 is generally rectangular and nearly point-symmetric, so that the RFID label 11 can be affixed without protruding from the label affixing area S in either orientation shown in FIG. 7(A) or 7(B). The RFID label 11a affixed to the first slip 5a and the RFID label 11b affixed to the second slip 5b are the same, but in order to distinguish the orientation in which they are affixed, the former will be referred to as the forward-affixed label 11a and the latter as the reverse-affixed label 11b below.

[0027] As shown in Figures 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 continuous paper 1. That is, in the form continuous paper 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 pairs alternately. As described above, in the folded form continuous paper 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 pairs alternately, as shown in Figures 3 and 8, in the folded form continuous paper 1, the forward-attached labels 11a and the reverse-attached labels 11b will be arranged in a row alternately in the stacking direction.

[0028] In this embodiment, by alternately stacking the forward-attached labels 11a and the reverse-attached labels 11b in the stacking direction, the pressure applied to the IC chip 15 can be reduced compared to stacking RFID labels 11 of the same orientation in the stacking direction. More specifically, as shown in FIG. 7, the IC chip 15 is positioned off-center in the RFID label 11. In the forward-attached label 11a, it is positioned to the left of the center of the label (see FIG. 7(A)), and in the reverse-attached label 11b, it is positioned to the right of the center of the label (see FIG. 7(B)). Therefore, as shown in FIG. 7(C), the IC chips 15 of the forward-attached label 11a and the reverse-attached label 11b, which are stacked in the stacking direction, do not overlap in the stacking direction. As shown in FIG. 9, the protrusions bulging out from the IC chip 15 placement area 28 of the forward-attached label 11a and the protrusions bulging out from the IC chip 15 placement area 28 of the reverse-attached label 11b are positioned offset in the left-right direction.

[0029] In this way, in this embodiment, the range in which the RFID label 11 can be attached to the form slips 5a, 5b is limited, but by alternately attaching pairs of first form slips 5a with forward-attached labels 11a attached and second form slips 5b with reverse-attached labels 11b attached, the number of IC chips 15 stacked in the stacking direction can be reduced, which has the advantage of reducing the load on the IC chips 15. Furthermore, in this embodiment, the same RFID label 11 is attached to the first form slip 5a and the second form slip 5b, and only one type of RFID label is required for the continuous form paper 1, so this can be achieved without increasing the cost of the RFID labels, and there is also no variation in performance between the first form slip 5a and the second form slip 5b.

[0030] 7(C), the forward-attached label 11a and the reverse-attached label 11b, which are stacked one on top of the other, are arranged so that their respective IC chips 15 do not overlap with each other's antennas 16 in the stacking direction. As shown in FIG. 6, the RFID label 11 has a thinner portion 26 where the antenna 16 is not provided than the portions 27 and 29 where the antennas 16 are provided. Therefore, by arranging the IC chips 15 of the forward-attached label 11a and the reverse-attached label 11b so that they do not overlap with the other's antennas 16, the thickness of the portion 28 where the IC chips 15 are provided in the folded continuous form 1 can be reduced by the thickness of the antennas 16.

[0031] 7, the antenna 16 is disposed such that the center of the rectangular, annular multiple loop wire 19 coincides with the center of the RFID label 11, and the multiple loop wires 19 of the forward-attached label 11a and the reverse-attached label 11b, which overlap in the stacking direction, overlap over the entire circumference. As shown in FIG. 6, the location 27 of the antenna 16 (multiple loop wire 19) is thicker and protrudes higher than the non-location 26 of the antenna 16. Therefore, by overlapping the locations of the multiple loop wire 19 of the forward-attached label 11a and the reverse-attached label 11b in the stacking direction, the location of the multiple loop wire 19 in the folded continuous form 1 becomes relatively thick, making it easier for pressure to be applied to this location, which makes it easier to distribute pressure applied to the location 28 of the IC chip 15.

[0032] In particular, since the IC chip 15 is formed inside the multiple loop wire 19, if the forward-sticking label 11a and the reverse-sticking label 11b, which are overlapped in the stacking direction as in this embodiment, have their respective multiple loop wires 19 overlapping around their entire circumference, the pressure applied to the IC chip 15 can be distributed front to back and left to right, and the pressure applied to the IC chip 15 can be distributed evenly around it.

[0033] 7, the forward-attached label 11a and the reverse-attached 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.

[0034] 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.

[0035] The continuous form paper 1 of this embodiment can be produced by forming perforations 4 at the boundaries between the form pieces 5 in the long strip-shaped paper base material 3 that makes up the continuous form paper 1, and attaching pre-manufactured RFID labels 11 to the label attachment portion S of the first form piece 5a in the direction of the forward label 11a, and attaching them to the label attachment portion S of the second form piece 5b in the direction of the reverse label 11b. The forward label 11a and the reverse label 11b can be attached by preparing RFID labels 11 attached to release paper in two different orientations, and peeling the RFID label 11 attached in a different orientation from the release paper when attaching it to the forward label 11a or the reverse label 11b. Alternatively, a plurality of RFID labels 11 may be prepared with the same orientation attached to a release paper, and the label attachment device may reverse the orientation of the labels when attaching the forward-attached label 11a and when attaching the reverse-attached label 11b. [Example]

[0036] 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 10 is a development 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 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.

[0037] In the form continuous paper 1 of Example 1, the form segments 5 are folded one by one using accordion folds at all perforations 4 formed at the boundaries of the form segments 5 (see FIG. 2). However, in this example, as shown in FIG. 11, the form segments 5 are folded two by two using accordion folds at every other perforation 4. When the form segments 5 are folded two by two in this manner, every third form segment 5 overlaps in the same direction in the stacking direction, as shown in FIG. 12. Therefore, in this example, the first form segments 5a and the second form segments 5b are arranged alternately in groups of four in the longitudinal direction of the form continuous paper 51, so that the forward-attached labels 11a and the reverse-attached labels 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 the form segments are folded multiple by multiple.

[0038] 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.

[0039] In the above embodiment, the IC chips 15 of the first and second form pieces 5a and 5b are arranged with a left-right offset so that the IC chips 15 of both form pieces 5a and 5b do not overlap in the stacking direction, but the direction in which the IC chips 15 of both form pieces 5a and 5b are offset is not limited to the left-right direction, and may also be the front-back direction or diagonal direction.

[0040] The shape of the RFID label 11 is not limited to a rectangular shape, and may be a circle, an ellipse, a regular polygon, or any other shape that can overlap the original shape when rotated a predetermined angle along the paper surface of the form. In the above embodiment, the form 5 is composed of two types of form 5, the first form 5a and the second form 5b. However, in addition to the first and second form 5a, a third and a fourth form 5b may also be provided. For example, if the RFID label is circular or square, the number of overlapping IC chips 15 in the stacking direction can be reduced to half of that in the above embodiment by providing a third form 5a affixed by rotating the forward-attached label 11a by 90 degrees or a fourth form 5b affixed by rotating it by 270 degrees.

[0041] Furthermore, although the label attachment portion S in the above embodiment is the same size as the RFID label 11, if the label attachment portion S is larger than the RFID label 11, the forward-attached label 11a and the reverse-attached label 11b may be attached so that they are positioned in different directions from the label attachment portion S, thereby increasing the amount of misalignment of the IC chip 15 between the first form piece 5a and the second form piece 5b.

[0042] 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.

[0043] 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.

[0044] Furthermore, the antenna 16 in the above embodiment is configured so that the multiple loop wires 19 of the forward-attached label 11a and the reverse-attached label 11b overlap almost completely around the entire circumference, but it is sufficient for the multiple loop wires to overlap only partially in the width direction.

[0045] 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.
