Description

TECHNICAL FIELD The present invention relates to continuous form paper formed by continuously forming a plurality of pieces of form paper to which RFID labels are attached.

A continuous form sheet formed by folding a unidirectionally continuous form sheet into a bellows shape is generally called a fanfold paper. Among such continuous form sheets, there is known one in which an RFID label is affixed to each piece of form paper. In each slip of such continuous form paper, the portion where the IC chip included in the RFID label is arranged bulges, so that when the continuous form paper is folded, pressure from the stacking direction is applied to the portion where the IC chip is arranged. There is a problem that it is easy to concentrate and the IC chip is easily damaged. In order to solve this problem, for a plurality of slips of form paper that overlap in the same direction in the stacking direction, the RFID label sticking positions are shifted back and forth and left and right to reduce the number of IC chips that overlap in the stacking direction. It has been proposed to suppress local thickening of an IC chip arrangement portion in a folded state of the continuous paper (see Patent Document 1).

Japanese Patent No. 6475470

With conventional continuous form paper, the range in which RFID labels can be affixed to each slip of form may be limited due to specification restrictions. In such a case, with the configuration described in Patent Document 1, it is difficult to shift the sticking position of the RFID label so that the IC chips of the slips of slips overlapping in the same direction do not overlap in the stacking direction. Further, even if the RFID labels can be affixed so that the IC chips do not overlap each other, if the IC chips are not sufficiently separated from each other, the projections of the IC chip arrangement portions will interfere with each other. In some cases, the pressure applied to the IC chips in the folded state from the stacking direction cannot be sufficiently reduced.

The present invention has been made in view of the current situation, and relates to continuous form paper in which RFID-attached form paper strips are folded in a bellows shape, and the range in which the RFID label can be pasted on the form paper strips is limited. It is an object of the present invention to provide a configuration capable of suitably reducing pressure applied to an IC chip of an RFID label even in such a case.

The present invention relates to a continuous form sheet in which a plurality of slips of slips are continuous in one direction, and the strips of slips are folded one by one or in multiple pieces by folding back in a bellows shape at the boundary of the strips of slips of slips, An RFID label comprising an antenna and an IC chip connected to the antenna is affixed to one side surface of each of the slips of the form. is attached in a first orientation, and the same RFID label as the first group of slips is attached in a second orientation that is rotated by a predetermined angle from the first orientation. The RFID label of the first group of slips and the RFID label of the second group of slips partially or entirely overlap in the stacking direction, and The continuous form paper is characterized in that the IC chips are arranged so as not to overlap in the stacking direction.
Here, the "stacking direction" of the continuous form paper refers to the direction in which a plurality of slips of the continuous form paper are overlapped when the continuous form paper is folded.

With such a configuration, even if the positions where the RFID labels are attached to the first group of slips of form and the positions of the RFID labels of the second group of slips of slips are not shifted in the front, rear, left, and right directions, the first group of slips can be easily identified. Since the position of the IC chip of the second group of slips can be shifted, the IC chips of the first group of slips and the IC chips of the second group of slips will not overlap in the stacking direction when the continuous slip of the slip is folded. can be avoided. For this reason, according to the present invention, even if the continuous form paper has a limited area where the RFID label can be affixed to the slip of paper form, the number of IC chips that overlap in the stacking direction in the folded state can be reduced, and the IC chip can be attached to the IC chip. It becomes possible to reduce the applied pressure.
Further, according to the present invention, since RFID labels having the same configuration are attached to the first group of slips and the second group of slips of slips, the present invention can be realized without increasing the cost of the RFID labels. There is no variation in performance between the slip of paper and the slip of slip of the second group.

The planar shape of the RFID label of the present invention includes a substantially rectangular shape, a substantially square shape, a substantially elliptical shape, and a substantially circular shape. When the planar shape of the RFID label is substantially rectangular or substantially elliptical, the IC chip is arranged at a position off the center of the RFID label, and the direction rotated 180° from the first direction is taken as the second direction. By doing so, most of the RFID labels of the first group and second group of slips can be attached so as to overlap each other in the stacking direction, while the respective IC chips can be arranged so as not to overlap each other in the stacking direction. Further, when the planar shape of the RFID label is approximately square or approximately circular, even if the second orientation is rotated by 90° or 270° from the first orientation, the first group and the second group The IC chips can be arranged so that most of the RFID labels of the slips of slips are overlapped in the stacking direction while the respective IC chips are not overlapped in the stacking direction.

In the present invention, the first group of slips and the second group of slips, which overlap in the same direction in the stacking direction, have their respective IC chips aligned with the antenna of the other group of slips in the stacking direction. and at least a part of each of the antennas is arranged so as to overlap the antennas of the other group of slips in the stacking direction.

In each slip of form, the portion where the antenna of the RFID label is arranged is also raised and thick, though not as large as the portion where the IC chip is arranged. Therefore, if the IC chip is arranged so as not to overlap the antennas of the other group in the stacking direction, as in this configuration, in the folded continuous form paper, the thickness of the portion where the IC chip is arranged is the same as that of the other group. It can be reduced by the amount of the antenna. On the other hand, as for the antennas, if the antennas of the first group and the second group of slips of the form are arranged so as to overlap in the stacking direction, the thickness of the relevant part of the folded continuous form paper becomes relatively large, Since pressure is easily applied from the stacking direction, it is possible to disperse the pressure applied to the portion where the IC chip is arranged.

In the above configuration, the antenna is a multiple loop antenna, and the antenna of the first group of slips and the antenna of the second group of slips overlap in the stacking direction. It is suggested that an antenna jumper wire is provided.

The jumper wire is formed so as to straddle the inside and outside of the multiple loop antenna, and generally, the jumper wire is thickest at the multiple loop antenna of the RFID label. Therefore, if the jumper wire arrangement portion is included in the portion where the antennas of the first group and the second group of slips overlap, as in this configuration, pressure from the stacking direction is more likely to be applied to the overlapping portion of the antennas. As a result, it is possible to further reduce the pressure applied to the portion where the IC chip is arranged.

Further, according to the present invention, the antenna is a multiple loop antenna, the IC chip is arranged inside the multiple loop line of the antenna, and the multiple loop line of the first group of slips of business form, It is proposed that the multiple loop lines of the second group of slips of form are arranged so as to overlap in the stacking direction over the entire circumference of the multiple loop lines.

In such a configuration, when the continuous form paper is folded, the multiple loop antennas of the first group and the second group of form paper strips, which overlap in the same direction, overlap in the stacking direction around the IC chip arrangement portion. As a result, a relatively thick annular portion is formed so as to surround the portion where the IC chip is arranged, so that the pressure applied to the IC chip from the stacking direction can be uniformly distributed around the IC chip. . The overlapping of the multiple loop lines is not limited to the overlapping of the lines forming the multiple loop lines one by one. It is enough if they overlap each other.

As described above, according to the present invention, even if the RFID label is not shifted in the front, back, left, and right directions and attached to the slips of business forms that are folded in a bellows shape and overlapped in the stacking direction in the same direction, the IC of the RFID label can be Since the position of the chip can be shifted, even when the range where the RFID label can be affixed to the slip of paper is limited, the pressure applied to the IC chip of the RFID label can be preferably reduced.

FIG.

Embodiments according to the present invention will be described according to the following examples.
In the following embodiments, the first form piece 5a corresponds to the first group of form pieces according to the present invention, and the second form piece 5b corresponds to the second group of form pieces according to the present invention.
Further, in the following examples, the direction along the longitudinal direction of the continuous form paper (the continuous direction of the slip of the slip) is defined as the front-rear direction of the slip of the slip, and the direction along the short direction (width direction) of the continuous slip of the slip is defined as , the left-right direction of the slip of form. However, the present invention is not intended to be used limited only to the direction thus defined.

As shown in FIG. 1, the continuous form paper 1 of this embodiment is made up of a plurality of continuous form pieces 5 in one direction. All the slips of form paper 5 are rectangular with the same size and are continuous in the longitudinal direction of the continuous form paper 1 in the same direction. The continuous form paper 1 is composed of a long belt-shaped paper base material 3 made of high-quality paper or the like. A perforation 4 crossing the paper base material 3 in the width direction is formed at the boundary between the adjacent business form pieces 5 along the paper surface of the paper base material 3 . It is easy to bend and easy to cut off.

The continuous form paper 1 is fanfold paper, and as shown in FIG. As shown in 3, the slips of form 5 are folded one by one and transported and stored. When issuing a form using the form continuous paper 1 of the present embodiment, required information is printed on one side or both sides of each form piece 5 by a printer or the like, and the printed form piece 5 is perforated 4 . Separate it with and use it as a form. A known configuration can be applied to the basic configuration of the continuous form paper 1, so a detailed description thereof will be omitted.

As shown in FIG. 1, a substantially rectangular RFID label 11 is affixed to a predetermined label affixing portion S on one side of each slip of form 5 one by one. The RFID label 11 is composed of an RFID inlet 12 and a protective sheet 13 covering the RFID inlet 12, as shown in FIGS. The RFID inlet 12 is a non-contact, battery-less type that can transmit and receive signals such as commands and data in a non-contact manner with 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 arranged on the front side (arrangement surface side) of a thin-film inlet base material 14 . The inlet base material 14 is made of a substantially rectangular PET film, and the rear side of the inlet base material 14 is coated with an adhesive 23 for attachment to the paper base material 3 .

As shown in FIGS. 4 to 6, the antenna 16 is a multiple loop antenna in which a conductive wire is wound multiple times in a loop shape, and is printed on the surface of the inlet base 14 with a conductive paste. The antenna 16 includes a multiple loop wire 19 formed by winding a substantially rectangular annular loop fivefold, a pair of terminal wires 20 extending inside the multiple loop wire 19, and a multiple loop wire straddling over the multiple loop wire 19. It is composed of a jumper wire 21 that electrically connects the outer end of the loop wire 19 and one of the terminal wires 20 . The IC chip 15 is capable of electromagnetically storing required information, is placed on the terminal wire 20, and is bonded to the terminal wire 20 with an anisotropic conductive adhesive 17, thereby electrically connecting to the antenna 16. connected to

As shown in FIGS. 4 to 6, the protective sheet 13 has a substantially rectangular shape in plan view. The protective sheet 13 can be made of PET film or paper, and the back side thereof is coated with an adhesive 24 having a substantially uniform thickness. The protective sheet 13 is larger in vertical and horizontal dimensions than the planar shape of the RFID inlet 12, and is attached so as to cover the entire front side (arrangement surface side) of the RFID inlet 12 via an adhesive 24 on the back side. It is attached to the paper substrate 3 around the inlet 12 .

As described above, the RFID label 11 according to this embodiment has a structure in which the surface of the RFID inlet 12 is covered with the protective sheet 13. As shown in FIG. 4, the surface of the RFID inlet 12 is flat. Since there are undulations due to the IC chip 15 and the antenna 16, as shown in FIG. Specifically, as shown in FIG. 6, the RFID label 11 is thinnest at the outer peripheral portion 25 where the protective sheet 13 is attached to the paper substrate 3 . On the other hand, the portion 26 where the IC chip 15 and the antenna 16 are not arranged on the inlet base material 14 is raised thicker than the outer peripheral portion 25 by the thickness of the inlet base material 14 . Further, the portions 27 and 29 where the antenna 16 is arranged protrude from the outer peripheral portion 25 by the thickness of the inlet base material 14 and the antenna 16 . Furthermore, the mounting portion 28 of the IC chip 15 is raised thicker than the outer peripheral portion 25 by the thicknesses of the inlet base material 14 , the antenna 16 (terminal wire 20 ), and the IC chip 15 . Although the antenna 16 is basically formed with a substantially constant thickness, the jumper wire 21 is formed so as to straddle over the multiple loop wire 19. The raised portion is thicker than the loop wire 19 and terminal wire 20 arrangement portion 27 . As described above, the surface of the RFID label 11 according to the present embodiment is formed with unevenness following the shapes of the IC chip 15 and the antenna 16, and among them, the arrangement portion 28 of the IC chip 15 has a convex shape. It is very exciting. 4 and 6, the thickness of the RFID label 11 is shown to be thicker than the actual thickness for convenience of explanation, but the general thickness of the RFID label 11 is 1 mm or less.

The RFID labels 11 are affixed one by one so as to fit in a predetermined label affixing portion S of each slip of form 5 by adhesives 23 and 24 applied to the RFID inlet 12 and the protective sheet 13 . The label attaching portion S is a rectangular area having the same size as the planar shape of the RFID label 11 and is provided at the same position on all the slips of form 5 . More specifically, as shown in FIG. 1, the labeling section S is provided on one side of each slip of form 5 in the longitudinal direction and at the center in the lateral direction.

In this embodiment, as shown in FIG. 3, in the continuous form paper 1 folded in a bellows shape, the adjacent form paper strips 5 are overlapped with the front and back facing each other with the perforation 4 interposed therebetween, and the alternate form strips 5 are stacked. The front and back sides overlap each other in the same direction. For this reason, in the folded continuous form paper 1, the labeling portions S of the adjacent form pieces 5 do not overlap, and the labeling portions S of the RFID labels 11 of the alternate form pieces 5 overlap. As described above, the label attaching portion S has the same size as the RFID label 11, and the RFID label 11 cannot be attached while being shifted in the front, back, left, and right directions. 11 comrades overlap in the stacking direction. Specifically, in the continuous form paper 1 shown in FIG. The attached RFID labels 11 overlap in the stacking direction on the right side of the figure. On the other hand, in FIG. 3, the even-numbered slips 5 from the bottom overlap in the same direction with the attached surface of the RFID label 11 facing downward. overlap in the stacking direction on the left side of the drawing.

In this way, when the portion where the RFID label 11 is attached to each form piece 5 is limited, the RFID labels 11 overlap in the stacking direction on the folded continuous form paper 1 . On the other hand, in the present embodiment, the RFID label 11 is prevented from being damaged by forming the slips 5 of the RFID label 11 from two types, that is, the first slip 5a and the second slip 5b of the RFID label 11 having different sticking angles. are preventing. More specifically, the RFID label 11 is attached to the first slip of paper form 5a in the orientation shown in FIG. The RFID label 11, which is the same as the slip of paper 5a, is attached in an orientation rotated by 180° from the orientation shown in FIG. 7A along the plane of the paper. Since the RFID label 11 has a substantially rectangular shape and is substantially point-symmetrical, the RFID label 11 can be attached without protruding from the label attaching portion S in either direction of FIGS. 7A and 7B. . 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. The label 11a is also referred to as the reverse-attached label 11b.

As shown in FIGS. 1 and 2, the first form piece 5a and the second form piece 5b are continuous in the longitudinal direction of the continuous form paper 1, two by two. That is, in the form continuous paper 1, two first form pieces 5a are continued, followed by two second form pieces 5b, then two first form pieces 5a are continued again, and so on. 2, the first slips 5a and the second slips 5b are alternately provided. As described above, in the folded continuous form paper 1, every other form strip 5 is overlapped in the same direction. As shown in 3 and 8, in the folded continuous form paper 1, the forward-attached labels 11a and the reverse-attached labels 11b are alternately overlapped in the stacking direction.

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 more than when the RFID labels 11 facing the same direction are stacked in the stacking direction. becomes. More specifically, as shown in FIG. 7, the IC chip 15 is arranged at a position off the center of the RFID label 11, and is arranged to the left of the center of the label 11a in the forward label 11a (FIG. 7 (A )), and in the reverse-attached label 11b, it is arranged to the right of the center of the label (see FIG. 7(B)). Therefore, as shown in FIG. 7C, in the forward-attached label 11a and the reverse-attached label 11b, which overlap in the stacking direction, the respective IC chips 15 do not overlap in the stacking direction, and as shown in FIG. The projecting portion of the attached label 11a protruding toward the IC chip 15 arrangement portion 28 and the projecting portion of the reverse attached label 11b protruding toward the IC chip 15 arranged portion 28 are arranged at laterally offset positions. be.

As described above, in the present embodiment, the range where the RFID label 11 can be affixed to the slips 5a and 5b of the slips is limited. By alternately pasting the second slips 5b of the printed form 5b, the number of IC chips 15 stacked in the stacking direction can be reduced, and the load applied to the IC chips 15 can be reduced. In addition, in this embodiment, the same RFID label 11 is attached to the first form piece 5a and the second form piece 5b, and only one type of RFID label is used for the form continuous paper 1. Therefore, the cost of the RFID label can be reduced. It can be realized without increasing the capacity, and there is no variation in performance between the first slip of paper 5a and the second slip of paper 5b.

Further, in this embodiment, as shown in FIG. 7, the antenna 16 is not arranged at the symmetrical position of the IC chip 15 arrangement position with respect to the center of the RFID label 11, as shown in FIG. 7(C). Thus, the forward-attached label 11a and the reverse-attached label 11b, which overlap in the stacking direction, have their respective IC chips 15 not overlapping the other antenna 16 in the stacking direction. As shown in FIG. 6, the RFID label 11 is thinner at the portion 26 where the antenna 16 is not arranged than at the portions 27 and 29 where the antenna 16 is arranged. By arranging the IC chip 15 of the label 11b so as not to overlap the antenna 16 on the other side, the thickness of the portion 28 where the IC chip 15 is arranged in the folded continuous form paper 1 can be reduced by the thickness of the antenna 16. .

Further, in this embodiment, as shown in FIG. 7, the center of the rectangular ring-shaped multiple loop line 19 of the antenna 16 is arranged so as to coincide with the center of the RFID label 11. The label 11a and the reverse-attached label 11b are configured so that the respective multiple loop lines 19 are overlapped over the entire circumference. As shown in FIG. 6, the portion 27 where the antenna 16 (multiple loop line 19) is mounted is thicker than the portion 26 where the antenna 16 is not mounted. In 11b, if the locations where the multiple loop lines 19 are arranged overlap in the stacking direction, the thickness of the locations where the multiple loop lines 19 are arranged in the folded continuous form paper 1 becomes relatively thick, and pressure is applied to the locations. is easily applied, the pressure applied to the arrangement portion 28 of the IC chip 15 can be easily dispersed.

In particular, since the IC chip 15 is formed inside the multiple loop lines 19, each of the multiple loop lines 19 of the forward-attached label 11a and the reverse-attached label 11b, which overlap in the stacking direction, are fully formed as in this embodiment. Since the pressure applied to the IC chip 15 can be dispersed in the front, rear, left, and right directions if the IC chip 15 is overlapped over the circumference, the pressure applied to the IC chip 15 can be distributed uniformly around the periphery.

Further, in this embodiment, as shown in FIG. 7, the forward-applied label 11a and the reverse-applied label 11b, which overlap in the stacking direction, have a part of the jumper wire 21 of each antenna 16 connected to the multiple loop wire of the other antenna 16. 19 in the stacking direction. As described above, the portion 29 where the jumper wire 21 is arranged is the thickest among the portions where the antenna 16 is arranged (see FIG. 6). If the portion 27 where the line 19 is arranged overlaps in the thickness direction, the thickness of the portion of the folded continuous form paper 1 is equivalent to the thickness of the portion 29 where the IC chip 15 is arranged. Therefore, in this embodiment, the pressure applied to the arrangement portion 28 of the IC chip 15 can be largely distributed to the arrangement portion 29 of the jumper wire 21 .

In this embodiment, the first and second slips of form 5a and 5b facing the same direction are alternately arranged in the stacking direction. Since the numbers of overlapping first and second slips of paper 5a and 5b are kept substantially equal, there is an advantage that pressure is less likely to be concentrated on the IC chip 15 of one of the first slip of paper 5a and the second slip of paper 5b.

The continuous form paper 1 of the present embodiment has a long belt-shaped paper base material 3 that constitutes the continuous form paper 1, and perforations 4 are formed at the boundaries of the form pieces 5, and an RFID label 11 is manufactured in advance. can be manufactured by attaching the forward label 11a to the label attaching portion S of the first form piece 5a and attaching the reverse label 11b to the label attaching portion S of the second form piece 5b. The forward-attached label 11a and the reverse-attached label 11b are separately attached, with the RFID label 11 attached to release paper in two different orientations prepared. The RFID label 11 stuck in a different direction from the time of sticking to the front side may be peeled off from the release paper and stuck. In addition, a plurality of RFID labels 11 pasted in the same direction on a release paper are prepared, and the label pasting device changes the labels when pasting the forward pasting label 11a and when pasting the reverse pasting label 11b. may be reversed.

The present embodiment is obtained by partially changing the configuration of the first embodiment. For this reason, the same reference numerals are given in the text and the drawings to the same configurations as in the first embodiment, and detailed description thereof is omitted.
FIG. 10 is a developed view of the continuous form paper 51 of this embodiment. The continuous form paper 51 of the present embodiment is made up of a plurality of continuous form paper strips 5 in one direction in the same manner as in the first embodiment (see FIG. 1). 3. All the slips of form 5 are rectangular with the same size and are continuous in the longitudinal direction of the slips of form 5 . A perforation 4 crossing the paper base material 3 in the width direction is formed at the boundary between the adjacent slips 5 of the form, so that the paper base 3 can be easily bent and separated at the boundary between the slips 5 of the slips. It has become.

Here, in the continuous form paper 1 of the first embodiment, all the perforations 4 formed at the boundaries of the form paper strips 5 are bellows-folded, and the form paper strips 5 are folded one by one (see FIG. 2). In this embodiment, as shown in FIG. 11, the form paper strips 5 are folded in accordion folds at alternate perforations 4 so that the slips 5 are folded two by two. In this way, when the slips of the form 5 are folded two by two, as shown in FIG. 12, every third slip of the slips of the form is overlaid in the same direction in the stacking direction. For this reason, in the present embodiment, the first and second form pieces 5a and 5b are alternately arranged in four pieces in the longitudinal direction of the continuous form paper 51, so that the folded continuous form paper 51 , the forward-attached label 11a and the reverse-attached label 11b are alternately overlapped in the stacking direction. In this manner, the present invention can also be applied to continuous form paper in which multiple pieces of form paper are folded one by one.

In the above-described embodiment, the IC chips 15 of the first and second slips of paper 5a and 5b are shifted left and right so that the IC chips 15 of the first slip 5a and the second slip of paper 5b do not overlap in the stacking direction. The direction in which the IC chips 15 of the slips 5a and 5b are shifted is not limited to the left-right direction, but may be the front-rear direction or an oblique direction.

Further, the shape of the RFID label 11 is not limited to a rectangular shape, and may be a circular shape, an elliptical shape, a regular polygonal shape, or any other shape that can substantially overlap the original shape when rotated along the surface of the slip of paper by a predetermined angle. can be adopted. In the above embodiment, the slips of business form 5 are composed of two types of first slip of paper 5a and second slip of paper 5b. of slips of form paper may be provided. For example, when the RFID label has a circular or square shape, the third form piece of paper is affixed in an orientation rotated by 90°, or the fourth form piece is affixed in an orientation rotated by 270°. By providing a piece of paper, the number of IC chips 15 stacked in the stacking direction can be reduced to half that of the above embodiment.

Further, although the labeling portion S of the above embodiment has the same size as the RFID label 11, if the labeling portion S is larger than the RFID label 11, the forward-attached label 11a and the reverse-attached label 11b can be The IC chip 15 may be affixed so as to be shifted in different directions of the label affixing portion S, so that the deviation width of the IC chip 15 between the first form piece 5a and the second form piece 5b becomes large.

In the above embodiment, the first form pieces 5a and the second form pieces 5b are alternately arranged in the same direction in the stacking direction. It is sufficient that the first slip of paper 5a and the second slip of paper 5b are included in the slip of paper 5, and the first slip of slip of paper 5a and the second slip of slip of paper 5b do not have to be arranged alternately.

In the RFID label 11 of the first embodiment, the RFID inlet 12 is covered with the protective sheet 13. However, the protective sheet 13 may be omitted and the RFID label 11 may be composed only of the RFID inlet 12. FIG. Also, the protective sheet 13 may have the same size as the RFID inlet 12 or may be smaller than the RFID inlet 12 .

Further, the antenna 16 according to the above embodiment is configured such that the multiple loop lines 19 of the forward-attached label 11a and the reverse-attached label 11b overlap almost completely over the entire circumference. It is sufficient if a part of

Further, the multiple loop wire 19 according to the above-described embodiment has a substantially rectangular annular loop wound five times, but the multiple loop wire according to the present invention may have a shape other than a rectangular annular shape such as an annular shape. Alternatively, the number of turns can be changed as appropriate.
