(Configuration example of label-type non-contact type data carrier device 1)
1-3 is a figure which shows the structure of the label type non-contact-type data carrier apparatus 1 which concerns on one Embodiment of this invention. FIG. 1 is a plan view of the label-type non-contact data carrier device 1 as viewed from the front side (printed surface side). FIG. 2 schematically shows the thickness direction emphasized to about 100 times the width direction. FIG. 3 shows the label-type non-contact data carrier device 1 in a state where the adhesive material layer N2 is exposed after being separated (peeled) from the release sheet 40 on the back side. It is the top view seen from the sticking surface side). In FIG. 1, a rectangular area indicated by a broken line indicates the outer shape of the non-contact type data carrier inlet 20, and a rectangular area indicated by a two-dot chain line indicates the outer shape of the magnetic material sheet 30. Both are covered with the print-receiving sheet 10 and are not visible from the surface of the non-contact type data carrier device 1. In the following description and drawings, the non-contact type data carrier inlet may be expressed as an inlet.

  As shown in FIGS. 1 to 3, the label-type non-contact data carrier device 1 includes a print-receiving sheet 10, a non-contact data carrier inlet 20, and a magnetic sheet 30 that are mutually connected via an adhesive material layer. In addition to being laminated, an adhesive material layer is laminated and integrated on the back surface side with the print sheet 10 side as the front surface side, and is separably stuck onto the release sheet 40. These members constituting the label-type non-contact type data carrier device 1 are each formed into a sheet shape (plate shape) having a thickness suitable as a label.

  As shown in FIG. 2, the print-receiving sheet 10 constituting the uppermost layer of the label-type non-contact data carrier device 1 and the inlet 20 arranged in the lower layer are bonded by an adhesive material layer 50. The inlet 20 and the magnetic sheet 30 are bonded by the adhesive material layer N1. An adhesive material layer N2 is laminated and integrated on the back surface of the magnetic sheet 30. The non-contact type data carrier device 1 as a laminated body integrated with these layers is formed on the release sheet 40 by the adhesive force of the adhesive material N2 and the exposed portion of the adhesive material 50 provided on the back side of the printing sheet 10. It is attached so that it can be separated.

    As shown in FIGS. 1 to 3, the printed sheet 10 has an outer shape (planar shape) larger than the outer shape of the inlet 20 and the magnetic sheet 30 (for example, about 2 to 12 mm in terms of the width Wd). ing.

  That is, the edge E 1 of the print-receiving sheet 10 covers the inlet 20 and the magnetic sheet 30 beyond the edge E 2 of the inlet 20 and the edge E 3 of the magnetic sheet 30. At the same time, the portion of the print-receiving sheet 10 that exceeds the edge E2 of the inlet 20 and the edge E3 of the magnetic sheet 30 is placed on the surface (release agent application surface) 40a of the release sheet 40 via the adhesive 50. It is comprised so that it may be stuck.

  Therefore, the adhesive layer exposed on the end face of the label-type non-contact type data carrier device 1 is only the edge of the adhesive layer 50 laminated on the back side of the print-receiving sheet 10, and the adhesive layer N1 between the material sheet layers. , N2 edge is not exposed. Therefore, the stickiness of the side surface of the non-contact type data carrier device 1 is suppressed.

  Here, the width Wd of the portion of the print-receiving sheet 10 beyond the edge portions of the non-contact data carrier inlet 20 and the magnetic sheet 30 is preferably at least 2 mm or more, more preferably 4 mm or more. . That is, the non-contact type data carrier inlet 20 and the magnetic sheet are at least 2 mm or more preferably 4 mm or more in width from the respective edges of the non-contact type data carrier inlet 20 and the magnetic sheet 30. It is good to form large so that 30 may be covered. Thus, by setting the width Wd of the portion beyond the edge to be 2 mm or more, preferably 4 mm or more, the peripheral portion of the adhesive layer 50 provided on the back surface of the print-receiving sheet 10 is sufficiently bonded to the release sheet 40. Will come to do. Therefore, it is possible to prevent the edge of the label-type non-contact data carrier device 1 (the edge of the print-receiving sheet 10) from being lifted off from the release sheet 40 in a normal storage state. Of course, the edge can be made difficult to lift even after being attached to an article or the like. Therefore, it is possible to prevent peeling due to a decrease in adhesive force caused by dust or the like entering from the edge.

  Note that the outer shape of the inlet 20 is larger than the antenna formed on the inlet 20 (for example, around 1 to 2 mm in circumference). The magnetic sheet 30 is formed to be equal to or slightly larger than the outer shape of the antenna of the inlet 20 (for example, about 1 to 4 mm). The reason why the magnetic material sheet 30 is equal to or slightly larger than the outer shape of the antenna of the inlet 20 is to ensure that the outer shape of the antenna of the inlet 20 is not affected by the metallic article. is there. Therefore, the magnetic material sheet 30 may be smaller than the outer shape of the main surface of the inlet 20 itself.

  As an example of the size of the outer shape of each of these constituent members, when the outer shape of the antenna of the inlet 20 is a substantially rectangular shape having a width of 45 mm and a length of 27 mm, the inlet 20 has a width Wt of about 47 to 49 mm and a length Lt. The magnetic material sheet 30 has a width Wm of 48 mm and a length Lm of 30 mm, and the print-receiving sheet 10 has a width Wp of 58 mm and a length Lp of 40 mm. If the external size of the antenna changes, it may be changed accordingly.

  The total thickness of the label-type non-contact data carrier device 1 is, for example, about 50 μm to 150 μm at the thin part and about 250 μm to 500 μm at the thick part. Therefore, in actuality, the label-type non-contact data carrier device 1 has a flat plate shape that hardly feels a difference in thickness, and is a space generated when the adhesive material 50 is not stuck on the release sheet 40. Is not as large as the space indicated by the open triangles in FIG. Therefore, by adopting this configuration, there is no problem with the adhesive force of the surface of the label-type non-contact data carrier device 1 attached to the article.

  In addition, the magnitude | size of the external shape of each of these structural members is not restricted to this example. As described above, the sheet to be printed 10 only needs to be configured so as not to expose the other sheet-like constituent members and the edge of the interlayer adhesive layer for bonding them together. A desired size can be selected. In this example, the outer shape of the sheet-like material constituting each layer is rectangular (however, the corners are slightly rounded). However, the shape is not limited to the rectangular shape. It may be a bowl shape, a character shape, or other shapes. Further, the thickness is not particularly limited to the numbers exemplified above.

  The label-type non-contact data carrier device 1 is used in a state where the lowermost release sheet 40 is peeled off (separated) and the adhesive layer is exposed when sticking to an article. Therefore, the state separated from the release sheet 40, the state where the release sheet 40 is adhered, and the state where any of the states are attached are referred to as the label-type non-contact data carrier device 1.

  Next, each member which comprises the label type non-contact type data carrier device 1 of this embodiment will be described in order.

  The printed sheet 10 is a sheet-like (plate-like) member that forms the surface of the label-type non-contact data carrier device 1. The surface 10a of the sheet 10 to be printed is a surface to be printed on which characters, designs, and the like are printed. The printed surface 10a is exposed on the uppermost layer of the non-contact data carrier device so that the label-type non-contact data carrier device 1 is manufactured (for example, after shipment) by a label printer or by handwriting. Has been. On the printed surface 10a of the label-type non-contact type data carrier device as a finished product, a character string or a pattern may be printed or may not be printed yet. As a material of the printing surface 10a or the printing sheet 10, a sheet for a label surface (printing surface) generally, such as synthetic paper, glossy paper, high-quality paper, etc. mixed with a synthetic resin such as polypropylene (PP). It can select suitably from the well-known material which can be used as.

  The non-contact type data carrier inlet 20 is a member that is functionally the core of the label-type non-contact type data carrier device 1 and has a basic function as a non-contact type data carrier. In the present invention, the configuration of the non-contact type data carrier inlet is not particularly limited. The non-contact type data carrier inlet has an antenna and an IC chip and functions as a non-contact type data carrier. If it is what is done. In the present embodiment, as an example, a portion where an IC chip is not mounted is about 80 μm, and a portion where an IC chip is mounted is about 150 μm. A specific example of the configuration of the non-contact data carrier inlet 20 used in the present embodiment will be described later.

  The magnetic material sheet 30 is a magnetic material layer composed of a magnetic material having a high magnetic permeability using a base material film P3 made of a synthetic resin having electrical insulation and flexibility, such as polyethylene terephthalate (PET), for example. 31 is a sheet-like (plate-like) laminated and integrated in advance. The thickness of the magnetic sheet 30 can be selected as appropriate. For example, the thickness of the magnetic layer 31 is 100 μm and the thickness of the base film P3 is 25 μm, which is 125 μm in total.

  Here, the magnetic material sheet 30 has a configuration in which the magnetic material layer 31 is reinforced by being integrated with the base film P3 so that it can withstand relatively high tensile stress, bending stress, and the like. When manufacturing the data carrier 1, it becomes easy to handle in the form of a roll (magnetic sheet base roll R30). Thereby, the productivity of the label-type non-contact data carrier device 1 can be increased.

  By providing the magnetic sheet 30 between the inlet 20 and the attachment surface to the article, the magnetic field for transmission / reception of the reader / writer introduced from the antenna A of the inlet 20 passes through the magnetic layer 31, Since it is guided to the introduced side, generation of eddy current due to the metal article can be prevented, and a situation where the label-type non-contact data carrier device 1 becomes unable to communicate can be avoided.

  The release sheet 40 is also a label support base that supports the label-type non-contact data carrier device 1 and covers the adhesive surface to be attached to the article before being attached to the article. A release agent (release agent) is applied to the surface 40 a of the release sheet 40. Therefore, the label-type non-contact data carrier device 1 stuck on the surface 40a (release agent application surface 40a) can be easily separated by being peeled off from the release sheet 40. On the other hand, the release agent is not applied to the back surface 40 b of the release sheet 40. In addition, as the peeling sheet 40, the thing similar to the peeling sheet (release paper) of a general label can be used.

  The label-type non-contact type data carrier device 1 shown in FIG. 1 to FIG. 3 is manufactured in the form of a roll in large numbers and separated into single sheets along the perforations of the folding sewing machine (cut line). Is. Therefore, the trace of the folding sewing machine remains on the end portion of the release sheet 40, and a catch mark is printed on the back surface 40b of the release sheet 40 for use as a mark for controlling the label manufacturing apparatus ( Although not shown here, see FIGS. 19 and 20). Of course, since it is not always necessary to manufacture in the form of a roll, the folding sewing machine and the catch mark may not be provided.

  As shown in FIGS. 2 and 3, in this embodiment, the magnetic sheet 30 is provided with a hole 33 having a size sufficient to accommodate the IC chip C at a position corresponding to the IC chip C. ing. For example, a circular hole (hole) having a diameter of about 3 to 4 mm is formed. The non-contact type data carrier inlet 20 is disposed by fitting the IC chip C into a hole 33 provided in the magnetic sheet 30. The antenna coil A of the non-contact type data carrier inlet 20 is partially or entirely buried in the lower adhesive material layer N1 and a part of the adhesive material layer N1 is pushed by the IC chip C into the hole 33. It is in the inserted state.

  Thus, by providing the hole 33 in the magnetic sheet 30 and burying the IC chip C of the non-contact type data carrier inlet 20 in the hole 33, the hole 33 is not provided in the magnetic sheet 30. Compared with the case where the non-contact type data carrier inlet 20 is arranged facing down and the case where the IC chip C is arranged facing the printed sheet 10 side, the non-contact type data carrier device 1 is made thinner. It can be made flatter. In addition, by fitting the IC chip C into the hole 33 provided in the magnetic sheet 30 as described above, the IC chip C is also protected from physical impact from the outside.

  Of course, it is not necessary to provide the hole 33 in the magnetic material sheet 30, or the IC chip C of the non-contact type data carrier inlet 20 may be arranged toward the printed sheet 10 side.

  FIG. 4 is an enlarged cross-sectional view of the configuration of the adhesive material N1 that bonds the non-contact data carrier inlet 20 and the magnetic sheet 30 in this embodiment. As shown in the figure, in this embodiment, the adhesive material N1 has a thickness made of an adhesive material having pressure sensitive adhesive at room temperature on both surfaces of a base film P1 made of polyethylene terephthalate (PET) having a thickness of 25 μm. It has a three-layer structure in which adhesive layers A1 and A2 of about 20 to 25 μm are laminated and integrated. The total thickness of the three layers is, for example, about 65 to 75 μm. As shown by a two-dot chain line in FIG. 4, a transparent release paper F1 is laminated on the upper surface of the adhesive layer A1 on the upper side of the base film P1, and the lower surface of the adhesive layer A2 of the base film P1 is opaque. The release sheet F1 above and below the adhesive sheet roll with release paper in which a long release adhesive sheet with release paper having a five-layer structure formed by further laminating release paper S2 is wound into a roll shape, This is because S2 is peeled off (removed) and laminated as the adhesive material N1. For the same reason, the adhesive material N2 that bonds the magnetic sheet 30 and the release sheet 40 also has the same configuration as N1 shown in FIG. In this way, it is relatively easy to manufacture by using the adhesive sheet with release paper, which is pre-coated with adhesive on both sides of the base film P1, dried and laminated and integrated with the release paper, as the base paper of the adhesive material. There is an effect that can be done. In addition, this structure is an example and the structure of adhesive material N1, N2 is not restricted to this. Moreover, since the layer which comprises the sticking surface to articles | goods should just have adhesiveness in normal temperature, in the case of a layer which is not exposed as an sticking surface to articles | goods, it replaces with adhesive material N1 and N2. Alternatively, an adhesive layer having no tackiness at room temperature may be provided and bonded.

  By the way, in this embodiment, the adhesive materials 50, N1, and N2 are colorless and transparent, and the magnetic material sheet 30 has a color (for example, gray brown, yellow brown, brown) reflecting the color of the magnetic material. Therefore, when the non-contact type data carrier device 1 is viewed from the back side with the release sheet 40 peeled off and the adhesive material layer exposed, as shown in FIG. 3, the magnetic material sheet 30 and the IC chip C can be seen through. It is in a state.

  Therefore, as shown in FIGS. 5 and 6, the adhesive layer N2 on the back surface of the magnetic sheet 30 and the surface 40a of the release sheet 40 of the label-type non-contact data carrier device 1 in the state shown in FIGS. For example, the sheet-like insulating layer 60 and the adhesive material layer N3 may be further laminated and integrated to form the label-type non-contact data carrier device 100. The sheet-like insulating layer 60 is an opaque sheet such as white plain paper or a sheet on which characters and patterns are drawn on the back surface, and is larger than the inlet 20 and the magnetic sheet 30 as shown in FIG. It is preferable to form smaller than the printing surface sheet 10. By further laminating such an opaque insulating layer 60, the internal magnetic sheet 30 and the IC chip C can be made difficult to see when the release sheet 40 is peeled off, and the appearance can be improved. As the adhesive material N3, the same materials as the above-described adhesive materials N1 and N2 can be used, but are not limited thereto. In the case of the configuration of the label-type non-contact data carrier device 100, the number of adhesive material layers to be stacked further increases. Even in this case, as shown in FIG. 5 and FIG. 6, the non-contact type data carrier inlet 20 prevents the printing surface sheet 10 from exposing the respective edge portions (end surfaces) of these adhesive material layers N1, N2, and N3. Since the magnetic sheet 30 is covered, the stickiness of the end face of the label-type non-contact data carrier device 100 can be suppressed.

  Also in this case, the width of the portion where the edge portion of the print-receiving sheet 10 exceeds the respective edge portions of the non-contact type data carrier inlet 20, the magnetic material sheet 30, and the sheet-like insulating layer 60 is the laminated body to be covered. Although it depends on the total thickness, it is preferably at least 2 mm or more, more preferably 4 mm or more. By doing so, the peripheral portion of the adhesive layer 50 provided on the back surface of the print-receiving sheet 10 is sufficiently adhered to the release sheet 40, and the label-type non-contact data carrier device 1 in the normal storage state. The edge (the edge of the print-receiving sheet 10) can be made difficult to lift from the release sheet 40. Of course, the edge can be made difficult to lift even after being attached to an article or the like. Therefore, it is possible to prevent peeling due to a decrease in adhesive force caused by dust or the like entering from the edge.

  In FIG. 7, the conductor pattern is indicated by hatching, and the conductor pattern formed on the front side (front side) and the conductor pattern formed on the back side thereof are distinguished by changing the hatching inclination direction. . However, among the conductor patterns formed on the front side surface, the thin conductor pattern is shown by a black region for easy viewing.

  As shown in FIGS. 7 to 9, the non-contact type data carrier inlet 20 used in the present embodiment includes a base film P2, an antenna coil A formed on the base film P2, and a base film P2. The pair of connection patterns 21a and 21b connected in parallel to the antenna coil A, the IC chip C mounted on the base film P2, and the pair of connection patterns 21a and 21b are connected to the base film P2. A plurality of capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b are provided mainly. Here, the “outer shape of the antenna” of the non-contact data carrier inlet 20 refers to the outer shape of the antenna as a whole and the antenna coil A and an electric circuit configured to be connected to the antenna coil A. It may be considered as the entire outer shape of the conductor pattern formed on P2. In this example, the “antenna external shape” is a substantially rectangular shape of 45 mm × 27 mm.

  The base film P2 is a film-like base material having electrical insulation and flexibility, and is made of, for example, polyethylene terephthalate (PET). In addition to this, for example, a phenol resin, It can also be composed of urea resin, melamine resin, polytetrafluoroethylene, polyethylene, polypropylene, polystyrene, polyethersulfone, polyphenylene sulfide, PBT, polyarylate, silicon resin, diallyl phthalate, polyimide, and the like. Here, although the base film P2 is formed in the rectangle, it is not restricted to this shape.

  The antenna coil A is formed in a spiral shape on the one surface 26a of the base film P2 so as to have a predetermined outer shape. Further, the pair of connection patterns 21a and 21b are respectively connected to the antenna coil A on the base film P2, and are respectively extended on one surface 26a and the other surface 26b of the base film P2. Specifically, one end portion 27a of the antenna coil A is connected to the proximal end portion of one connection pattern 21a, and one of the connection bumps 28 of the IC chip C is further connected to this portion.

  On the other hand, the other end portion 27b of the antenna coil A is connected to one end portion Ya of a jumper wire (inter-terminal connection pattern) Y wired on the other surface 26b of the base film P2 via a crimping portion 29a. Furthermore, the other end portion Yb of the jumper line Y is connected to the base end portion of the wiring pattern 29c wired on the one surface 26a of the base film P2 via the crimping portion 29b. The other end of the connection bump 28 of the IC chip C is connected to the tip of the wiring pattern 29c. Furthermore, the other end portion Yb of the jumper wire Y described above is connected to the base end portion of the connection pattern 21b on the other surface 26b of the base film P2.

  In addition, the capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b are connected to the connection pattern 21a so as to be opposed to the one surface 26a and the other surface 26b across the base film P2. , 21b. Each of the pair of capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b is formed in a rectangular shape and functions as a capacitor pattern, and a capacitor (capacitance portion) 22 is provided between them. , 23, 24. Here, the shape of each of the pair of capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b is rectangular, but the shape is not particularly limited and is formed in a substantially circular shape or the like. May be.

  In addition, the above-described IC chip C is mounted with a capacitor 25 and the like in addition to a rewritable nonvolatile memory and an RF circuit for wireless communication that do not require power supply backup (see FIG. 9). As shown in FIG. 9, the antenna coil A, the capacitor 25 in the IC chip C, and the capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b that are respectively connected on the base film P2 as described above. A resonant circuit for the entire antenna is configured.

  Here, by removing at least one of the capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b, the capacitors of the capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b are removed. Function can be removed, and the capacitance can be adjusted. Also, for example, the capacitance can be adjusted by removing a part of the connection patterns 21a and 21b and disconnecting them. In this case, the same effect as that obtained when all of the capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, 24b, 25a, and 25b are removed can be obtained.

  In this embodiment, when the label-type non-contact data carrier device 1 having a configuration in which the magnetic sheets 30 are laminated as shown in FIGS. 1 to 3 is attached to a metal article, the target value of the resonance frequency is set. A mode in which a circular through hole (hole) is formed at the position indicated by the symbol H in FIGS. 7 and 8b is illustrated so that a frequency approximate to 13.56 MHz as an example is obtained. By making the hole H at this position, the capacitance adjustment patterns 22a, 22b, 23a, and 23b are not connected to the IC chip C and do not function as a capacitor pattern (capacitance portion).

  Of course, it is also possible to obtain a frequency that approximates 13.56 MHz, which is an example of the target value of the resonance frequency, without removing any set of capacitance adjustment patterns. Moreover, the set value of the resonance frequency is not limited to 13.56 MHz.

  Further, here, the non-contact type data carrier inlet 20 provided with the capacitance adjustment patterns 22a, 22b, 23a, 23b, 24a, and 24b has been described as an example, but the present invention is not limited to this configuration. It is not something that can be done. For example, a configuration may be used in which an electrostatic capacity adjustment pattern is not provided and an antenna coil and an IC chip that transmits and receives information via the antenna coil are provided on a base film. In other words, in the present invention, the configuration of the contactless data carrier inlet is not particularly limited, and includes at least an antenna and an IC chip that transmits and receives information via the antenna, and in a predetermined frequency band. Any device having a communicable configuration may be used.

(Method for manufacturing label-type non-contact data carrier device)
Next, an example of a manufacturing method of the label-type non-contact data carrier device 1 described above will be described with reference to FIGS. Of course, the label-type non-contact data carrier device according to the present invention can be manufactured by a method other than the manufacturing method described below as an example.

  FIG. 10 is a diagram showing an outline of the manufacturing process for an example of the manufacturing method of the label-type non-contact data carrier device 1 described above. 11, FIG. 13, FIG. 15, FIG. 17, FIG. 19, FIG. 21, and FIG. 23 are plan views schematically showing what is manufactured in each manufacturing process. 18, FIG. 20, FIG. 22, and FIG. 24 are vertical cross-sectional views schematically showing corresponding parts.

  In FIG. 10, a substantially rectangular shape with rounded corners indicates a “material” such as a material or a product, and a rectangular shape without rounded corners indicates a “process” and “processing contents” performed in the process. Yes. An arrow indicates that an object or a process is directly related (there is a dependency), and indicates that an object or a process flows from the root of the arrow toward the arrow tip.

  In addition, in these drawings and this specification, the name “XX seal” is, in principle, “a laminate in which an adhesive material layer is laminated on the back surface of It is used in the sense of “a laminate attached to release paper by the adhesive strength of the layer, or a laminate thereof”. The “OO seal” that is the laminate can be peeled off from the release paper (separated) and reattached to something else.

  As shown in FIGS. 10 to 24, this manufacturing method includes a print sheet seal forming step S <b> 101 for forming the print sheet seal 71, and an inlet seal in which the non-contact type data carrier inlet 20 is made into a predetermined outer shape. And the sheet seal 71 to be printed is laminated on the inlet seal 72 so that the edge portion of the inlet seal 72 is not exposed. Integrated labeling step S103 for forming a sheet-to-be-printed inlet seal 73, magnetic sheet seal forming step S104 for forming a magnetic sheet seal 74 using the magnetic sheet 30 as a seal, and label support provided with a release sheet 40 A label support substrate forming step S105 for forming the substrate 75, and this label support substrate 75 And step S106 to integrate by laminating magnetic sheets seal 74, which further has a step S107 to integrate by laminating the print sheet with the inlet seal 73, a.

  That is, in this manufacturing method, after the members constituting the label-type non-contact data carrier device 1 are sealed with a predetermined outer shape for each member or for each member group that should have the same outer shape. These seals are sequentially aligned and pasted in an appropriate order, with the release paper (release sheet) as the label support base as the bottom layer. According to this manufacturing method, it is possible to easily form the outer shape of each component member in a desired shape and size, unlike the case where all the component members are stacked and then subjected to the outer shape punching process. Therefore, according to this manufacturing method, it is possible to easily manufacture the label-type non-contact data carrier device 1 having the configuration described with reference to FIGS. 1 to 3, and the problem that the end face is sticky is solved.

  As shown in FIG. 10, the print sheet seal forming step S101, the inlet seal forming step S102, the magnetic sheet seal forming step S104, and the label support substrate forming step S105 are not dependent on each other. Or may be performed concurrently. Further, since there is no dependency among the steps S103, S104, and S105, these may be performed in any order, or may be performed in parallel.

  Hereinafter, the steps indicated by reference numerals S101 to S107 in FIG. 10 will be described in detail in the order of these numbers.

(Creation of printed sheet seal (roll))
First, the printing sheet seal forming step S101 will be described.

  First, as a base material (base paper) of the print-receiving sheet 10, a width sufficient to create a large number (for example, 1000) of the print-receiving sheets 10 having a predetermined outer shape (for example, both sides from the width Wp of the print-receiving sheet 10). To be printed) and a print-receiving sheet base paper roll R10 that is a sufficiently long sheet is prepared. The roll length of the sheet-to-be-printed sheet roll R10 is not particularly limited. However, it is necessary to be able to pick a large number of sheets and be long enough to be handled by the label manufacturing apparatus.

  As this printing sheet base paper roll R10, there is prepared a roll of a long sheet in which the adhesive material 50 is previously applied (laminated) on the back surface, dried, and further laminated with the release sheet S1. It is preferable to do. As such a printing sheet base paper roll R10, a commercially available one as a label base material can be used. By using the printing sheet base paper roll R10 with such an adhesive material and release paper, it is possible to save time and labor for separately laminating the adhesive material and the release sheet, and to produce a large amount at a low cost. Needless to say, the print sheet base paper roll is not limited to this, and a roll to which the adhesive material 50 is not applied in advance may be used. Needless to say, a sheet on which characters and designs are printed in advance on the printing surface may be used as the printing sheet base paper.

  Subsequently, based on the printing sheet base paper roll R10, using a label manufacturing apparatus, die-cutting (outside shape processing) so as to have a predetermined shape (rectangular shape with a width Wp and a length Lp) at regular intervals, The unnecessary printed sheet layer and the adhesive material layer are removed from the release paper S1 (up the residue) and wound up (see FIGS. 10, 11, and 12). When the outer shape of the printing sheet 10 is punched, the release paper S1 is not punched out, but half-cut as shown in FIGS. 11 and 12, leaving the release paper S1 as it is. This process is the same as that performed in general label processing, and can be performed with the same apparatus.

  Here, the “constant interval” is not limited as long as the edges of the print-receiving sheets 10 do not overlap each other and can be handled by the label manufacturing apparatus. The “predetermined shape” of the outer shape of the print-receiving sheet 10 is as described above. That is, the printed sheet 10 covers the non-contact type data carrier inlet 20 and the magnetic sheet 30 beyond the edges of the non-contact type data carrier inlet 20 and the magnetic sheet 30 and is adhesive. The outer shape may be large enough to be attached to the release sheet 40 or the article to be attached via the material 50. Here, as shown in FIGS. 1 and 11, a rectangular shape having a width Wp (for example, 58 mm) and a length Lp (for example, 40 mm) with four corners slightly rounded is used.

  In this way, as shown in FIGS. 11 and 12, the printed sheet 10 having the outer shape removed is separated on the release sheet S1 with the printed surface 10a as the front surface and the adhesive material 50 laminated on the back surface. A printable sheet seal 71 that can be attached is obtained. A long sheet-like sheet in which a large number of print-receiving sheet seals 71 are arranged at regular intervals is wound into a roll to obtain a print-receiving sheet seal roll 71R.

  It is also possible to print on the printing surface 10a when the printing sheet 10 is cut out. For example, a brand name, a model number, a serial number, a UID (unique ID), and the like may be printed as appropriate. Usually, it is printed after the label is completed, not when the outline is removed.

(Create inlet seal (roll))
Next, the inlet seal forming step S102 will be described.

  First, a non-contact type data carrier inlet roll R20 in which a large number of non-contact type data carrier inlets before being cut into a predetermined outer shape are formed at a predetermined interval (predetermined pitch Pt) (the adhesive layer is not laminated on the back surface). And an adhesive sheet roll RN1 with release paper having a predetermined width and a sufficient length (not shown).

  Here, the predetermined pitch Pt is set to be longer than the length Lp of the outer shape of the printing sheet 10. This is because the individual sheet-to-be-printed sheet seals 73 formed on the sheet-to-be-printed sheet seal roll 71R are pasted on each non-contact type data carrier inlet 20 of the inlet seal roll 72R in the subsequent step S103.

  The adhesive sheet roll RN1 with release paper used here has a five-layer structure in which release papers F1 and S2 are laminated on both surfaces of an adhesive material N1 having a three-layer structure as described with reference to FIG. It is wound around. Here, although the thing of such a structure was used as the base paper roll (base material roll) of the adhesive material N1, it is not limited to this.

  Subsequently, these two rolls R20 and RN1 are set as base paper rolls in a label manufacturing apparatus capable of performing laminating, punching and punching together. And using this label manufacturing apparatus, the non-contact type data carrier inlet roll R20 is unwound on the adhesive layer N1 while peeling the release paper (not shown) on the upper surface side of the adhesive sheet with release paper. The non-contact type data carrier inlet 20 and the adhesive material layer N1 are subjected to outer shape cutting (half cut) so as to have a predetermined outer shape, and the unnecessary portion of the sheet is wound up. (Uplift) and take up the necessary part (see FIG. 10, FIG. 13, FIG. 14).

  As a result, as shown in FIGS. 13 and 14, the non-contact type data carrier inlet 20 and the adhesive material N1 were laminated and integrated, cut to a predetermined outer shape, and adhered onto the release paper S2. A large number of inlet seals 72 in a state are arranged at a predetermined pitch Pt to obtain an inlet seal roll 72R wound in a roll shape.

  The “predetermined outer shape” of the non-contact type data carrier inlet 20 and the adhesive material is a rectangular shape having a width Wt (for example, 47 mm) and a length Lt (for example, 29 mm) as shown in FIGS. Shaped. This is larger by 1 mm than the 45 mm × 27 mm which is the outer shape of the antenna. The reason why a slight margin is given to the outer shape of the antenna is to prevent the antenna from being disconnected during the punching process, and the outer shape of the non-contact type data carrier inlet 20 is unnecessarily large. It is also for not. This “slight margin” is not limited to this, and may be appropriately set according to the accuracy of the processing machine, the characteristics of the sheet material, and the like. Moreover, it is not restricted to a rectangular shape.

  Here, when the non-contact type data carrier inlet 20 is laminated on the adhesive material N1, in this embodiment, as described above, the IC chip mounting surface is disposed downward. By doing so, the final contactless data carrier device 1 has a configuration in which the IC chip mounting surface faces downward as shown in FIG. Of course, in the case of a configuration with the IC chip mounting surface facing upward, the IC chip mounting surface is disposed facing upward.

  In addition, here, the through hole H for adjusting the capacitance is formed at a predetermined position simultaneously with the outer shape punching (half cut) of the non-contact type data carrier inlet 20 (see FIGS. 7, 8b, 13, and 14). ). As shown in this example, by performing the outer shape punching and drilling simultaneously in the same process using the same manufacturing apparatus, it is possible to process efficiently and accurately, and to improve productivity and quality.

  In this way, the non-contact type data carrier inlet 20 and the adhesive material layer N1 are laminated and integrated with the IC chip mounting surface facing the adhesive material layer N1, and half cut into a predetermined outer shape, and at a predetermined position. A large number of inlet seals 72 each having a hole H for adjusting capacitance are arranged on the release paper S2 at a predetermined pitch Pt to obtain an inlet seal roll 72R wound in a roll shape (FIG. 13). FIG. 14).

  In this example, the punching process is performed at the same time as the outer shape punching process, and the through hole H for adjusting the capacitance is formed. However, in the state of the non-contact type data carrier inlet roll R20, a static position is fixed in advance. A through hole H for adjusting the capacitance may be opened. Although a hole punching process may be performed after the outer shape punching process, it is necessary to make a hole at least before the printing sheet 10 is laminated. If the holes are formed after the non-contact type data carrier inlet 20 and the print sheet 10 are laminated and integrated, there will be holes in the uppermost print surface 10a of the non-contact type data carrier device. is there. In addition, when the outer shape punching and the hole punching are performed separately, it is necessary to pay sufficient attention so as not to cause displacement. Of course, in the case of a configuration in which it is not necessary to make the hole H, it is not necessary to perform the drilling process.

  Further, as shown in FIG. 14, here, not only the thickness of the non-contact type data carrier inlet 20 but also the hole H is formed so as to penetrate to the adhesive material layer N1 and the release paper S2. It is not limited to this. If the hole 20 is perforated by the thickness of the inlet 20, the function for adjusting the capacitance is sufficient.

(Lamination of printed sheet seal and inlet seal)
Next, step S103 in which the inlet seal 73 is stacked and integrated with the print-receiving sheet seal 71 will be described.

  In this step S103, the individual sheet-to-be-printed sheet seals 71 produced in the previous step S101 are peeled off from the sheet-to-be-printed sheet roll 71R, and each inlet seal disposed on the inlet seal roll 72R produced in the previous step S102. Then, the layers are sequentially stacked on each other and integrated with each other (see step S103 in FIG. 10, FIG. 15, and FIG. 16). This operation is a so-called labeling process (labeling process), and can be performed using a normal labeling apparatus.

  As a result, an inlet seal 73 with a print-receiving sheet, and an inlet seal roll 73R with a print-receiving sheet in which a large number of the inlet seals 73 with a print-receiving sheet are bonded and wound on the release sheet S2 are obtained (FIG. 15). And FIG. 16). Note that the sheet seal 71 to be printed is not yet laminated on the inlet seal 72 shown at the right end of FIGS. 15 and 16, but this is because the inlet seal roll 72R shown in FIG. It shows how they are stacked one after another.

  At the time of this labeling process, as shown in FIG. 15, the print sheet seal 71 covers the entire surface of the inlet seal 72, and the portions of the print sheet seal 71 beyond the edge portions of the inlet seal 72 become uniform. That is, in other words, the inlet seal 72 is aligned and laminated so as to be disposed at the center of the print-receiving sheet seal 71. It is necessary to laminate so that at least the adhesive layer at each edge of the inlet seal 72 is not exposed. This is to prevent stickiness due to the exposure of the adhesive layer at the edge of the inlet seal 72.

  The inlet seal 73 with print sheet and the inlet seal roll 73R with print sheet formed in this way are not final products as the non-contact data carrier device 1 according to the present embodiment. However, only a magnetic layer (magnetic sheet) is not laminated, and the configuration and function as a non-contact data carrier device are provided. Therefore, this itself is an intermediate product that may be used as a non-contact data carrier device without a magnetic layer.

(Magnetic sheet seal (roll) formation)
Next, the magnetic sheet seal forming step S104 for forming the magnetic sheet seal 74 will be described.

  First, a magnetic sheet base paper roll R30 serving as a base paper for the magnetic sheet 30 and an adhesive sheet roll RN2 with release paper serving as a base paper for the adhesive material N2 are prepared (see FIG. 10). The magnetic sheet base paper roll R30 has the same configuration as the magnetic sheet 30 having the configuration described with reference to FIGS. 1 and 2, that is, the base film P3 and the magnetic layer 31 are laminated and integrated, and on the back surface. What is necessary is just to prepare what the adhesive material is not laminated | stacked, and the long sheet | seat was wound by roll shape.

  As the adhesive sheet roll RN2 with release paper, since the configurations of the adhesive materials N1 and N2 are the same, the same one as the adhesive sheet roll RN1 with release paper used in the inlet seal forming step S102 can be used. By unifying the material of the pressure-sensitive adhesive material, it is possible to obtain an effect that the material is hardly wasted. Of course, since it is not necessary to make adhesive material N1 and N2 the same structure, you may use another adhesive material roll with release paper according to each situation.

  The roll lengths of the magnetic sheet base paper roll R30 and the release sheet-attached adhesive sheet roll RN2 are not particularly limited, but are long enough to take a large number of magnetic sheets 30 at a predetermined interval, and a label manufacturing apparatus For example, the length is about 50 to 500 m.

  Subsequently, the two base paper rolls R30 and RN2 are set in a processing machine capable of performing laminating and punching at the same time as described in the inlet seal forming step S102. Then, laminating and punching are performed using this processing machine. That is, while peeling the release paper (not shown) on the upper surface side of the adhesive sheet with release paper, the magnetic sheet base roll R30 is unwound on the adhesive layer N2, and the magnetic layer 31 side is Laminate the upper part, perform the outer shape punching (half cut) of the magnetic material sheet 30 and the adhesive layer N2 so as to have a predetermined outer shape, wind up unnecessary portions (lift up), and wind up the necessary portions (See FIGS. 10, 17, and 18).

  As a result, as shown in FIGS. 17 and 18, the magnetic sheet 30 and the adhesive layer N2 are laminated and integrated, cut to a predetermined outer shape, and stuck on the release paper S3. A magnetic sheet seal roll 74R is obtained in which a large number of magnetic sheet seals 74 are arranged at regular intervals and wound into a roll.

  Here, the “predetermined external shape” of the magnetic material sheet 30 and the adhesive material layer N2 is a rectangular shape having a width Wm (for example, 48 mm) and a length Lm (for example, 30 mm) as shown in FIGS. It was. The lengths of the width Wm and the length Lm are not limited to this, but are at least equal to or slightly larger than the outer shape of the antenna so as to cover the antenna of the non-contact type data carrier inlet 20. By doing so, the magnetic field introduced from the reader / writer to the antenna can be shielded against the side of the surface to be adhered to the article, and it is possible to avoid the occurrence of eddy current and the inability to communicate.

  Here, the magnetic material sheet 30 is laminated on the adhesive material layer N2 with the magnetic material layer 31 side facing up (the base film P3 and the adhesive material layer N2 face each other), and the outer shape is cut (half-finished). At the same time as cutting, a through hole 33 for avoiding a chip having a size sufficiently larger than the IC chip C is formed in a region corresponding to the region where the IC chip C of the non-contact type data carrier inlet 20 is mounted (FIG. 2). 3, FIG. 17, FIG. 18). Here, a circular hole having a diameter of 4 mm was formed.

  In this way, the magnetic sheet 30 and the adhesive material layer N2 are laminated and integrated to be half-cut into a predetermined outer shape, and a magnetic sheet seal 74 having a hole 33 for avoiding a chip at a predetermined position. However, a large number of magnetic sheet seal rolls 74 </ b> R were provided on the release paper S <b> 3 at regular intervals and wound in a roll shape (see FIGS. 17 and 18).

  In this example, laminating, outer shape punching, and drilling are all performed in the same process using the same processing apparatus (label manufacturing apparatus). These may be performed at different times by different processing apparatuses, but at least before they are laminated on the label support base 75, they need to be completed. In addition, when the outer shape punching and the hole punching are performed separately, it is necessary to pay sufficient attention so as not to cause displacement. Of course, as described above, when the through hole 33 for avoiding the chip is not formed, it is not necessary to perform the drilling process. As in this example, by performing the outline punching and drilling simultaneously in the same process using the same processing device, it can be processed efficiently and accurately, and the productivity and quality can be improved. .

  In addition, as shown in FIG. 18, here, the holes 33 are formed so as to penetrate not only the thickness of the magnetic sheet 30 but also the adhesive material layer N2 and the release paper S3. Not limited. Depending on the thickness of the IC chip and the thickness of the magnetic sheet 30, and depending on the function and performance of the processing apparatus, the holes 33 may be formed by the thickness of the magnetic sheet 30.

(Label support substrate (roll) formation)
Next, a label support substrate forming step S105 for forming a label support substrate 75 and a label support substrate roll 75R as a substrate for supporting the label-type non-contact type data carrier device 1 will be described with reference mainly to FIGS. It explains using.

  First, as the label support base paper roll R40, here, a long sheet having a predetermined width Ws is rolled in a three-layer structure in which a release sheet 40 and a dummy sheet 43 are laminated so as to be peelable through an adhesive layer N4. We prepared what was wound around. Although it does not specifically limit as label support base paper roll R40, For example, the roll-shaped thing of commercially available what is called tack paper (tack label paper) can be used.

  The adhesive material layer N4 and the dummy sheet 43 are peeled off in this manufacturing process, and do not remain in the configuration of the label-type non-contact data carrier device 1 of this embodiment. Therefore, as the label supporting base 75, the release sheet 40 is substantially sufficient. That is, as the label support base paper roll R40, it is only necessary that the long release sheet 40 having a predetermined width Ws is wound in a roll shape.

  Here, as shown in FIGS. 19 and 20, a release agent (release agent) is applied to one surface 40a of the release sheet 40, and a release agent is applied to the other surface 40b of the release sheet 40. Is not applied. A dummy sheet 43 is laminated on the release material application surface 40a side of the release sheet 40 via an adhesive material layer N4. The release material non-application surface 40b is exposed. This release material non-application surface 40b is the back surface of the release sheet 40 which is the lowermost layer (label support base) of the label-type non-contact data carrier device 1.

  Subsequently, as shown in FIG. 19 and FIG. 20, the label support base paper roll R40 is developed into a sheet shape with the back surface side of the release sheet 40 (the release material non-application surface 40b side) facing upward, A fold perforation 42 is formed at each predetermined interval Ls, and a catch mark 41 having a predetermined size is printed at a predetermined position.

  This catch mark is a mark that is necessary for causing a device such as a label printing machine or a label processing machine to recognize the position of each label and controlling the sheet feed amount. When producing labels in the form of rolls, it is usually necessary to print catch marks. The specific configuration of the catch mark depends on the apparatus and the control method thereof, but here, the catch mark is a black square of 5 mm square. The fold perforation 42 is used to easily separate the individual non-contact data carrier device 1 by hand, and is also called a cut line or the like. The fold perforation 42 can be formed by performing perforation using an apparatus capable of perforating.

  Here, the predetermined width Ws is the same as the width Ws of the release sheet 40 of the non-contact data carrier device 1 that is the final product, and the predetermined interval Ls is the release sheet 40 of the non-contact data carrier device 1. It is the same as the length Ls (see FIG. 1). In this example, Ws is 70 mm and Ls is 43 mm, but the present invention is not limited to this.

  In this way, on the back surface (release agent non-application surface) 40b side of the release sheet 40, fold perforations 42 that can be separated into individual pieces are formed at a predetermined interval Ls, and the rectangles are separated by the respective fold perforations 42. A predetermined catch mark 41 was printed at one corner of the four corners of the region to obtain a label support base roll 75R wound in a roll shape (see FIGS. 19 and 20). A portion partitioned by each fold perforation 42 is an individual label support base 75.

(Lamination of magnetic sheet seal (labeling))
Next, step S106 for laminating the magnetic sheet seal 74 will be described.

  In this step S106, only the release sheet 40 is pulled out by peeling the dummy sheet 43 together with the adhesive material N4 from the label support base roll 75R produced in the previous step S105, and the previous release agent application surface 40a is subjected to the previous step. The individual magnetic sheet seals 74 produced in step S104 are peeled off from the magnetic sheet seal roll 74R and sequentially stacked and integrated (see step S106 in FIG. 10, FIG. 21, and FIG. 22). This operation is a so-called labeling process, and can be performed using a normal labeling apparatus.

  As a result, as shown in FIGS. 21 and 22, the holes 33 are formed at predetermined positions on the front surface 40a side of the release sheet 40 where the catch marks 41 and the perforations 42 are formed on the back surface 40b side as the label support base. A large number of opened magnetic sheet seals 74 were separably attached to obtain a roll 76R wound in a roll shape.

  Here, in FIG. 22, details of the configuration of the magnetic sheet seal 74 are omitted. 18 and FIG. 22, the laminated body indicated by reference numeral 76 is a laminated body in which the magnetic sheet seal 74 is bonded onto the release sheet 40, and the magnetic sheet 30 and the release sheet. 40 is also a laminated body that is laminated and stuck via an adhesive material N2.

(Lamination of inlet seal with printed sheet (labeling))
Next, step S107 for stacking and integrating the inlet seal 73 with the print-receiving sheet will be described.

  The roll 76R produced in the previous step S106 is continuously sent out with the surface of the magnetic sheet seal 74 facing upward, and on each magnetic sheet seal 74, in the previous step S103. The individual inlet seals 73 with the printed sheet are peeled off from the release paper S2 and sequentially stacked and integrated (see step S107 in FIG. 10, FIG. 23, and FIG. 24). This operation is a so-called labeling process (labeling process), and can be performed using a normal labeling apparatus.

  In this labeling process, as shown in FIGS. 23 and 24, the inlet seal 73 with the print-receiving sheet covers the entire surface of the magnetic sheet seal 74, and each edge of the magnetic sheet seal 74 of the print-receiving sheet seal 71 is shown. The magnetic material sheet seal 74 is aligned and laminated so that the portion beyond the portion is even, that is, the magnetic sheet seal 74 is disposed at the center of the inlet seal 73 with print-receiving sheet (substantially the print-receiving sheet 10). It is necessary to laminate so that at least the adhesive layer at each edge of the magnetic sheet seal 74 is not exposed. This is to prevent stickiness due to exposure of the adhesive layer at the edge of the magnetic sheet seal 74.

  As described above (see FIGS. 2 and 16), in the inlet seal 73 with the print sheet peeled off from the release paper S2, the IC chip mounting surface of the non-contact type data carrier inlet 20 faces the adhesive surface side. It has a configuration. The magnetic sheet seal 74 is provided with a hole 33 having a size enough to accommodate the IC chip C at a position corresponding to the IC chip mounting area. Therefore, when labeling is performed, the IC chip C and the hole 33 are aligned so as to face each other and stacked.

  By doing so, as shown in FIG. 2, the IC chip C and a part of the adhesive material N <b> 1 are in a state of being recessed into the hole 33. Therefore, the IC chip C is protected from external pressure, impact, and the like, and the non-contact data carrier device 1 is also thinned. Further, since the IC chip C does not protrude, as shown in FIG. 2, there is an effect that the surface of the label-type non-contact data carrier device 1 (printed surface 10a) can be configured to be relatively flat. By configuring the printing surface 10a to be relatively flat, the effect of facilitating printing on the printing surface 10a can be obtained.

(Completion of label-type non-contact data carrier device 1)
As described above, the label-type non-contact type data carrier device 1 according to the present embodiment has the release surface of the release sheet 40 as the label support base with the adhesive surface (being an attachment surface to the article) facing down. On the coating surface 40a, a non-contact type data carrier device roll 1R was obtained in which a large number of non-contact data carrier device rolls 1R were partitioned by the fold perforations 42 and continuously arranged. The end face of the non-contact type data carrier device 1 was not sticky.

  The label-type non-contact type data carrier device roll 1R thus obtained is provided in this roll form. After a character string, a pattern, etc. are printed on the to-be-printed surface 10a, you may provide with a roll form. It may be cut along the perforation 42 and provided in a single wafer form. Alternatively, it may be provided in the form of a bellows folded along the perforation 42. Even in this case, the label-type non-contact data carrier device 1 does not stick to each other due to the stickiness of the end face of the label-type non-contact data carrier device 1. Of course, it may be provided in other forms.

(Other)
As shown in FIGS. 5 and 6, when the insulating layer 60 and the adhesive material N3 are further laminated on the release sheet 40, the label support substrate forming step S105 shown in FIG. Thereafter, before the step S106 of laminating the magnetic seal 74, the insulating layer 60 and the adhesive material N3 are laminated (laminated) and cut into a predetermined outer shape (an outer shape equivalent to the magnetic sheet seal) for insulation. Step S108 (not shown) for forming a layer seal, Step S109 (not shown) for sticking the insulating layer seal to a predetermined position on the release agent application surface of the release sheet 40 as a label support base, Can be done. Alternatively, in the label support substrate forming step S105, a predetermined outer shape may be punched and scraped up before the dummy sheet 43 constituting the label support substrate base paper roll R40 is peeled off. Then, in the step S106 of laminating the magnetic seal 74, the magnetic seal 74 may be stuck as it is without peeling off the remaining portion of the dummy sheet 43 and the two layers of the adhesive material N4. By doing so, the label-type non-contact data carrier device 100 having the configuration shown in FIGS. 5 and 6 can be manufactured more easily. In this case, by making the insulating layer 60 and the dummy sheet 43 opaque, as described with reference to FIGS. 5 and 6, the internal magnetic layer can be made difficult to see and the appearance can be improved.

  In addition, this invention is not limited only to the said embodiment. Various modifications can be made without departing from the spirit of the present invention.

  For example, a conductive metal layer and an adhesive material layer may be laminated and integrated between the magnetic sheet seal 74 (magnetic sheet 30) and the label support base sheet 75 (release sheet 40). By doing so, the resonance frequency of the non-contact type data carrier inlet can be adjusted in a state where the magnetic layer and the conductive metal layer are laminated in advance, so that the label type non-contact type data carrier device can be attached. Regardless of whether the symmetrical article is a conductive article such as a metal or a non-conductive article, a non-contact data carrier device capable of communication can be provided. Even in such a configuration, as described above, a long sheet composed of a conductive metal layer and an adhesive sheet roll with release paper are laminated (laminated) as a base paper roll. It can be easily manufactured by performing outer shape punching and laminating (labeling).

  In this way, even in the case of a non-contact type data carrier device having a multi-layered structure, as described with reference to FIGS. What is necessary is just not to expose the end surface of the interlayer adhesive material layer which adhere | attaches a multilayer sheet-like material mutually. By doing so, it is possible to provide a label-type non-contact type data carrier device and a label-type non-contact type data carrier device roll that do not have a sticky end surface.

  Moreover, although the method of manufacturing with the form of the roll of 1 row was demonstrated as an example above, it is not restricted to this, The form of the roll of multiple rows may be sufficient. Further, a plurality of sheets of a desired size such as A4 standard paper may be manufactured in a form in which a plurality of sheets are arranged in rows and columns at a desired interval.

  Furthermore, in the above description, the outer shape of the sheet-like material constituting each layer is a rectangular shape, but is not limited to a rectangular shape, and may be an arbitrary shape such as a circular shape, an elliptical shape, a bowl shape, and a character shape. Even in that case, the same applies. That is, the printed sheet that is the uppermost layer has a large edge so that the edge of each sheet extends beyond each edge of the lower sheet-like material (non-contact type data carrier inlet, magnetic material sheet, etc.). In addition to the formation, an adhesive layer may be provided on the back surface of the sheet to be printed at the part beyond the surface. The width of the portion where the edge portion of the print-receiving sheet exceeds these edge portions is at least 2 mm or more, preferably 4 mm or more at any location. By doing so, the edge of the label-type non-contact type data carrier device is hardly peeled off.

  As an example of this, FIG. 25 shows an example of a label-type non-contact data carrier device 200 when the outer shape is an oval. In the figure, the release sheet is omitted. As shown in the figure, even when the print-receiving sheet 210 is oval and the non-contact data carrier inlet 220 and the magnetic sheet 230 are circular, the print-receiving sheet 210 has a non-contact type data at its edge. The effect of the present invention that the adhesive layer at the end is not sticky can be obtained by forming the carrier inlet 220 and the magnetic sheet 230 so as to cover the inlet 220 and the magnetic sheet 230 beyond the respective edges. Furthermore, the width (Wd shown in FIG. 25) of the portion where the edge of the print-receiving sheet 210 exceeds each edge of the non-contact type data carrier inlet 220 and the magnetic sheet 230 is at least 2 mm, preferably 4 mm or more. Thus, the edge of the label-type non-contact data carrier device 200 (printed sheet 210) can be made difficult to peel off. In this example, the width Wd at which the edge of the print-receiving sheet 210 exceeds the edges 220 and 230 is not constant, but the minimum portion of the width Wd may be at least a predetermined width (for example, 2 mm) or more. . In addition, it goes without saying that an adhesive layer is provided on the back surface of the print-receiving sheet 210 in the part beyond the above.
