Description

The present invention relates to a continuous form sheet consisting of multiple continuous pieces of form paper to which RFID labels are affixed.

Continuous form paper, formed by folding continuous form strips in one direction so that they overlap in an accordion-like manner, is generally called fanfold paper. One such continuous form paper with an RFID label affixed to each strip is known. Because the location of the IC chip included in the RFID label on each strip of such continuous form paper is raised, when the continuous form paper is folded, pressure from the stacking direction tends to concentrate on the location of the IC chip, making the IC chip susceptible to damage. To solve this problem, it has been proposed to offset the affixing positions of the RFID labels on multiple overlapping form strips in the same direction in the stacking direction, front to back and left to right, thereby reducing the number of overlapping IC chips in the stacking direction and preventing localized thickening of the IC chip location when the continuous form paper is folded (see Patent Document 1).

Patent No. 6475470

With conventional continuous form paper, specification constraints can limit the range in which RFID labels can be attached to each piece of form paper. In such cases, with the configuration described in Patent Document 1, it becomes difficult to shift the attachment position of the RFID labels so that IC chips on overlapping form paper 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 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 from the stacking direction when the paper is folded may not be sufficiently reduced.

The present invention was made in consideration of this current situation, and aims to provide a configuration that can effectively reduce the pressure applied to the IC chip of an RFID label when a continuous form in which a piece of form paper with an RFID tag affixed thereto is folded accordion-like, even when the area on the piece of form paper where an RFID label can be affixed is limited.

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 overlapping 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.

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.

Examples of the planar shape of the RFID label of the present invention include a substantially rectangular, square, elliptical, and circular shape. When the planar shape of the RFID label is a substantially rectangular or elliptical shape, the IC chip is positioned off-center on the RFID label, and the second orientation is rotated 180 degrees from the first orientation. This allows the RFID labels of the first and second groups of slips of paper to be affixed so that most of the 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 circular shape, even when the second orientation is rotated 90 degrees or 270 degrees from the first orientation, it allows the RFID labels of the first and second groups of slips of paper to be affixed so that most of the labels overlap in the stacking direction, while the IC chips do not overlap in the stacking direction.

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 the antennas of the form paper pieces of the other group in the stacking direction, and that at least a portion of each antenna overlaps the antennas of the form paper pieces of the other group in the stacking direction.

On each piece of form paper, the area where the antenna on 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, with regard to the antenna, 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.

It is also proposed that in the above configuration, the antenna is a multiple loop antenna, and a jumper wire for the antenna is arranged in the area where the antenna of the first group of slips and the antenna of the second group of slips overlap in the stacking direction.

The jumper wire is formed so that it spans the inside and outside of the multiple loop antenna, and generally, in multiple loop antennas on RFID labels, the area where the jumper wire is located is the thickest. Therefore, by including the jumper wire location where the antennas of the first and second groups of slips of paper overlap, as in this configuration, pressure from the stacking direction is 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.

The present invention also proposes that the antenna be a multiple loop antenna, the IC chip be positioned 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 be arranged so as to overlap in the stacking direction around the entire circumference of the multiple loop wire.

In this configuration, when the continuous form paper is folded, the multiple loop antennas of the first and second groups of form paper pieces, which are stacked in the same direction, overlap in the stacking direction around the location where the IC chip is located. This creates a relatively thick annular portion that surrounds the location where the IC chip is located, making it possible to evenly distribute the pressure applied to the IC chip from the stacking direction around the IC chip. Note that the overlap between the multiple loop wires does not have to be such that each individual wire constituting the multiple loop wire overlaps; it is sufficient if at least a portion of the bundle of wires constituting the multiple loop wire overlaps around the entire circumference.

As described above, according to the present invention, when RFID labels are attached to pieces of paper that are folded accordion-like and stacked in the same direction in the stacking direction, the position of the RFID label's IC chip can be shifted without having to be shifted back and forth or left and right. This makes it possible to effectively reduce the pressure on the RFID label's IC chip even when the area in which the RFID label can be attached to a piece of paper is limited.

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 referred to 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 referred to as the left-to-right direction of the form pieces. However, the present invention is not limited to these directions.

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 continued in the same direction along the length of the continuous form paper 1. The continuous form paper 1 is composed of a long, strip-shaped paper base material 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 material 3, perforations 4 are formed that run across 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 segment 5.

The form continuous paper 1 is fanfold paper, and as shown in Figure 2, it is folded back into an accordion-like shape by alternating mountain and valley folds at each perforation 4 formed at the boundaries of the form segments 5, resulting in the form segments 5 being 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 other device, and the printed form segments 5 are separated at the perforations 4 and used as a form. The basic structure of this form continuous paper 1 can be a well-known one, so a detailed description thereof will be omitted.

As shown in Figure 1, one approximately rectangular RFID label 11 is attached to a designated label attachment area S on one side of each slip of paper 5. As shown in Figures 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 uses HF electromagnetic waves to send and receive signals such as commands and data contactlessly between itself and an input/output device (reader/writer device) (not shown). The RFID inlet 12 has an antenna 16 and an IC chip 15 attached to the front side (mounting surface) of a thin-film inlet substrate 14. The inlet substrate 14 is made of an approximately 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.

As shown in Figures 4 to 6, the 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 the inlet substrate 14 with conductive paste. The antenna 16 is composed of a multiple-loop wire 19 formed by winding a roughly rectangular annular loop five times, a pair of terminal wires 20 extending inside the multiple-loop wire 19, and a jumper wire 21 that straddles the multiple-loop wire 19 and electrically connects the outer end of the multiple-loop wire 19 to one of the terminal wires 20. The IC chip 15 is capable of electromagnetically storing required information and is electrically connected to the antenna 16 by being placed on the terminal wire 20 and adhered to the terminal wire 20 with anisotropic conductive adhesive 17.

As shown in Figures 4 to 6, the protective sheet 13 has a generally rectangular shape in plan view. The protective sheet 13 can be made of PET film or paper, and has a substantially uniformly thick adhesive 24 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 (mounting surface) of the RFID inlet 12, and is also attached to the paper substrate 3 around the periphery of the RFID inlet 12.

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 has undulations due to the IC chip 15 and antenna 16. Therefore, as shown in FIG. 6, the surface of the RFID label 11 has irregularities that follow the shapes of the IC chip 15 and antenna 16. Specifically, as shown in FIG. 6, the RFID label 11 is thinnest at the outer periphery 25 where the protective sheet 13 is attached to the paper substrate 3. In contrast, a region 26 of the inlet substrate 14 where the IC chip 15 and antenna 16 are not disposed is raised higher than the outer periphery 25 by the thickness of the inlet substrate 14. Furthermore, the regions 27 and 29 where the antenna 16 is disposed 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 wires 20), and the IC chip 15. While the antenna 16 is generally formed with a substantially constant thickness, the jumper wire 21 is formed 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 terminal wires 20. Thus, the surface of the RFID label 11 according to this embodiment is formed with irregularities that mimic the shapes of the IC chip 15 and the antenna 16, with the mounting area 28 for the IC chip 15 being raised in a particularly large convex shape. For ease of explanation, the RFID label 11 is illustrated in Figures 4 and 6 as being thicker than it actually is; however, the thickness of a typical RFID label 11 is 1 mm or less.

The RFID labels 11 are attached one by one to each slip of paper 5 in a designated label attachment area S using adhesives 23, 24 applied to the RFID inlet 12 and protective sheet 13. The label attachment area S is a rectangular area the same size as the planar shape of the RFID label 11, and is provided in the same position on all slips of paper 5. Specifically, as shown in Figure 1, the label attachment area S is provided on one side of one side of each slip of paper 5 in the longitudinal direction, in the center of the short side.

In this embodiment, as shown in Figure 3, in the accordion-folded continuous form paper 1, 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 way 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.

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 on the folded form continuous paper 1. In contrast, in this embodiment, the form piece 5 is composed of two types of form piece 5, 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 Figure 7(A), while the same RFID label 11 as that on 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 Figure 7(A), as shown in Figure 7(B). The RFID label 11 is generally rectangular and nearly point-symmetric, so it can be attached without protruding from the label attachment area S in either orientation shown in Figures 7(A) or 7(B). The RFID label 11a attached to the first form piece 5a and the RFID label 11b attached to the second form piece 5b are the same, but to distinguish between their attachment orientations, the former will be referred to as the forward-attached label 11a and the latter as the reverse-attached label 11b below.

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 pairs, 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. Therefore, if the first form fragments 5a and the second form fragments 5b are arranged in pairs alternately, as shown in Figures 3 and 8, the forward-attached labels 11a and reverse-attached labels 11b will be arranged in pairs alternately in the stacking direction in the folded form continuous paper 1.

In this embodiment, by stacking the forward-attached labels 11a and the reverse-attached labels 11b alternately 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. 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 labels 11a and the reverse-attached labels 11b, which overlap in the stacking direction, do not overlap in the stacking direction. As shown in FIG. 9, the protrusions protruding from the IC chip 15 mounting positions 28 of the forward-attached label 11a and the reverse-attached label 11b are positioned offset from each other in the left-right direction.

Thus, in this embodiment, the range in which the RFID label 11 can be attached to the form slips 5a and 5b is limited. However, by alternately attaching pairs of first form slips 5a with forward-attached labels 11a and second form slips 5b with reverse-attached labels 11b, the number of IC chips 15 stacked in the stacking direction can be reduced, thereby 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. This can be achieved without increasing the cost of the RFID label, and there is also no variation in performance between the first form slip 5a and the second form slip 5b.

In addition, in this embodiment, as shown in FIG. 7, the antenna 16 is not disposed symmetrically with respect to the center of the RFID label 11 to the location where the IC chip 15 is disposed. As shown in FIG. 7(C), the IC chip 15 of the forward-attached label 11a and the reverse-attached label 11b, which overlap in the stacking direction, does not overlap the other's antenna 16 in the stacking direction. As shown in FIG. 6, the RFID label 11 has a thinner area 26 where the antenna 16 is not disposed than the areas 27 and 29 where the antenna 16 is disposed. 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 the other's antenna 16, the thickness of the area 28 where the IC chip 15 is disposed in the folded continuous form 1 can be reduced by the thickness of the antenna 16.

In addition, in this embodiment, as shown in FIG. 7, the center of the rectangular, annular multiple loop wire 19 of the antenna 16 is aligned 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, are configured to overlap over the entire circumference. As shown in FIG. 6, the placement area 27 of the antenna 16 (multiple loop wire 19) is thicker and raised than the non-placement area 26 of the antenna 16. Therefore, by overlapping the placement areas of the multiple loop wire 19 of the forward-attached label 11a and the reverse-attached label 11b in the stacking direction in this way, the thickness of the placement area of the multiple loop wire 19 becomes relatively thick in the folded continuous form 1, making it easier for pressure to be applied to this area, which makes it easier to distribute pressure applied to the placement area 28 of the IC chip 15.

In particular, since the IC chip 15 is formed inside the multiple loop wire 19, if the multiple loop wires 19 of the forward-attached label 11a and the reverse-attached label 11b, which are stacked in the stacking direction as in this embodiment, overlap 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 the periphery.

In addition, in this embodiment, as shown in Figure 7, the forward-attached label 11a and the reverse-attached label 11b, which overlap 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 jumper wire 21 installation area 29 is the thickest of all the antenna 16 installation areas (see Figure 6). Therefore, if the jumper wire 21 installation area 29 is overlapped in the thickness direction by the installation area 27 of the other multiple loop wire 19, the thickness of that area in the folded continuous form 1 will be comparable to the thickness of the IC chip 15 installation area 29. Therefore, in this embodiment, the pressure applied to the IC chip 15 installation area 28 can be largely distributed to the jumper wire 21 installation area 29.

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

The continuous form paper 1 of this embodiment can be manufactured by forming perforations 4 at the boundaries of the form pieces 5 in the long, strip-shaped paper base material 3 that constitutes 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 forward label 11a orientation, and attaching them to the label attachment portion S of the second form piece 5b in the reverse label 11b orientation. The forward label 11a and reverse label 11b can be attached by preparing RFID labels 11 attached to release paper in two different orientations, and peeling the RFID labels 11 attached in different orientations from the release paper and attaching them to the forward label 11a and reverse label 11b. Alternatively, multiple RFID labels 11 may be prepared with the same orientation attached to 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.

This embodiment is a partial modification of the configuration of embodiment 1. Therefore, the same components as those of 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 a plurality of continuous form paper fragments 5 arranged 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 fragments 5 are rectangular and of the same size, and are continuous in the longitudinal direction of the form paper fragments 5. At the boundaries between adjacent form paper fragments 5, perforations 4 are formed across 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 fragment 5.

In the form continuous paper 1 of Example 1, all perforations 4 formed at the boundaries of the form slips 5 are accordion-folded, and the form slips 5 are folded one by one (see Figure 2). However, in this example, as shown in Figure 11, the form slips 5 are folded two by two, and accordion-folded at every other perforation 4. When the form slips 5 are folded two by two in this manner, as shown in Figure 12, every third form slip 5a and every second form slip 5b are overlapped in the same direction in the stacking direction. For this reason, in this example, the first form slips 5a and the second form slips 5b are configured to be alternately connected in groups of four in the longitudinal direction of the form continuous paper 51, so that the forward-attached labels 11a and reverse-attached labels 11b are alternately overlapped 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 slips are folded multiple by multiple.

The above describes an embodiment of the present invention, but the present invention is not limited to the configuration of the above embodiment. For example, the configuration of the above embodiment can be modified as follows:

In the above embodiment, the IC chips 15 on the first and second form pieces 5a and 5b are offset left and right so that they do not overlap in the stacking direction, but the direction in which the IC chips 15 on the first and second form pieces 5a and 5b are offset is not limited to the left and right direction, and may also be forward and backward or diagonally.

Furthermore, the shape of the RFID label 11 is not limited to a rectangular shape, and can be a circle, ellipse, 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, third and 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 in a direction rotated 90 degrees from the forward-attached label 11a, or a fourth form 5b affixed in a direction rotated 270 degrees.

In addition, the label attachment portion S in the above embodiment is the same size as the RFID label 11, but 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 on the label attachment portion S, thereby increasing the misalignment of the IC chip 15 between the first form piece 5a and the second form piece 5b.

In addition, in the above embodiment, the first form piece 5a and the second form 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 first form piece 5a and the second form piece 5b are included among the form pieces 5 that are overlapped in the same direction in the stacking direction, and the first form piece 5a and the second form piece 5b do not have to be arranged alternately.

In addition, while the RFID label 11 in Example 1 above 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 composed of only the RFID inlet 12. Furthermore, the protective sheet 13 may be the same size as the RFID inlet 12, or may be smaller than the RFID inlet 12.

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.

Furthermore, while the multiple loop wire 19 in the above embodiment is formed by five approximately rectangular loops wound around it, the multiple loop wire of the present invention may have a shape other than a rectangular loop, such as a circular loop, and the number of windings can also be changed as appropriate.
