  The present invention relates to a tag tape that continuously forms a wireless tag capable of wireless communication of information with the outside in a tape shape, a tag tape roll, a wireless tag circuit element cartridge using the same, and a wireless tag IC that holds the wireless tag The present invention relates to a method for manufacturing a circuit holder.

  An RFID (Radio Frequency Identification) system that reads / writes information in a non-contact manner between a small wireless tag and a reader (reading device) / writer (writing device) is known. For example, a wireless tag circuit element provided in a label-like wireless tag includes an IC circuit unit that stores predetermined wireless tag information and an antenna that is connected to the IC circuit unit and transmits and receives information. Even if the battery is dirty or placed in an invisible position, the reader / writer can access (read / write information) the RFID tag information in the IC circuit unit, and manage the product. Practical use is expected in various fields such as inspection processes.

  Such a radio tag is usually formed by providing a radio frequency circuit element on a label-like base material, and is configured to be attached to an object by an adhesive material layer provided on the back side of the base material (= wireless). Tag label). An example of the structure is described in Patent Document 1, for example. In this conventional technique, a RFID tag circuit element (IC module) having an IC circuit part (IC chip) and an antenna part (transmission / reception part) is bonded to a surface substrate via an adhesive material layer and a thermoplastic resin layer. A wireless tag label having a structure is disclosed. In this RFID label, the adhesive material layer attachment side other than the RFID tag circuit element installation position is covered with a common release sheet together with the RFID tag circuit element attachment side, and the release sheet is peeled off when used by the user. As a result, the adhesive material layer around the RFID circuit element is exposed, and the entire label is attached to the object to be attached by the adhesive force.

It is arranged so as to be inserted between them, and a print R (in this example, “RF-ID” indicating the type of the RFID label T) is printed on the back surface of the cover film 103.

  FIG. 11 shows a screen displayed on the terminal 5 or the general-purpose computer 6 when accessing (reading or writing) the RFID tag information of the IC circuit unit 151 of the RFID circuit element To by the tag label producing apparatus 2 as described above. It is a figure showing an example.

  In FIG. 11, in this example, the tag label type, the print character R printed corresponding to the RFID circuit element To, the access (read or write) ID which is identification information unique to the RFID circuit element To, and the above information The address of the article information stored in the server 7 and the storage destination address of the corresponding information in the route server 4 can be displayed on the terminal 5 or the general-purpose computer 6. Then, the tag label producing apparatus 2 is activated by the operation of the terminal 5 or the general-purpose computer 6, and the print character R is printed on the cover film 103, and the read ID and article information stored in advance in the IC circuit unit 151. Or the like (or information such as the write ID and article information is written in the IC circuit unit 151).

  In the above description, an example in which the conveyance guide 13 is held in the access area and accessed (read or written) with respect to the moving printed tag label tape 110 in connection with the printing operation is shown. However, the access may be performed with the printed tag label tape 110 stopped at a predetermined position and held by the transport guide 13.

  Further, at the time of reading or writing as described above, the ID of the generated RFID label T and the information read from the IC circuit unit 151 of the RFID label T (or information written to the IC circuit unit 151) The correspondence relationship is stored in the route server 4 and can be referred to as necessary.

  In the present embodiment configured as described above, the wirelessly taken out as the printed tag label tape 110 from the cartridge 100 of the tag label producing apparatus 2 and set and held at a predetermined position (access area) facing the antenna 14 by the transport guide 13. The tag circuit element To is sequentially accessed (reading of the RFID tag information of the IC circuit unit 151 or writing to the IC circuit unit 151), and the RFID tag label T is cut by the cutter 15 for each RFID circuit element To. Is generated. The generated RFID label T is used after being peeled off by the user from the release paper 101e and exposing the adhesive layer 101d, and then attached to various articles and the like through the adhesive layer 101d.

The cover film 103, the adhesive layer 101a, the base film 101b, and the adhesive layer 101c, which are arranged so as to be inserted between them and are positioned so as to sandwich them from the opposite side of the antenna pattern sheet 161 in the thickness direction, It becomes a shape that rises so as to bypass them at the portion of To (see FIG. 7 and the like). However, in this embodiment, the first reduced thickness portions 160A, 160B, 160C, and 160D, which are thickness reducing means, are formed at the end of the protective film 160 that protects the IC circuit portion 151 of the RFID circuit element To. By gradually decreasing the thickness direction dimension toward the end side, the protrusion shape that can be generated at the end of the protective film 160 as it is can be relaxed and made smooth. As a result, it is possible to avoid the local pressing by sticking to the adhesive layer 101c widely with its smooth inclined surface, and thus preventing the adhesive layer 101c and further the base film 101b and the like from being deformed or damaged to reduce the durability. it can.

  Further, when the base tape 101 is wound in a roll shape, the base tape 101b can be neatly wound without forming wrinkles or uneven steps on the surface of the base film 101b, and the base tape in the apparatus main body 8 or the cartridge 100 can be wound. There is also an effect that the running performance of 101 becomes good. In the present embodiment, the first reduced thickness portions 160A, 160B, 160C, and 160D are formed on all four ends of the protective film 160. However, the present invention is not limited to this, and if the first reduced thickness portions 160A, 160B, 160C, and 160D are formed on at least one end. The above effect can be obtained at the formed end.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described.

(1) When the first reduced thickness portion having an arc-shaped cross-sectional shape is formed on the protective film FIG. 12 shows the first reduced thickness portion having the arc-shaped cross-sectional shape formed at each end of the protective film 160 in such a modification. It is a sectional side view of the RFID label T, and is a figure corresponding to FIG. 7 of the above embodiment. Components equivalent to those in FIG. 7 are denoted by the same reference numerals, and description thereof is omitted as appropriate.

  In FIG. 12, in this modification, instead of the first reduced thickness portions 160A and 160B having a triangular cross-sectional shape formed at each end portion of the protective film 160 in the above embodiment, the thickness direction dimension is continuous toward the end side. Arc-shaped first reduced thickness portions 160a and 160b having an arc-shaped cross-sectional shape that gradually decreases are formed.

  Also according to the present modification, by forming the arc-shaped first reduced thickness portions 160a and 160b, each end portion of the protective film 160 is provided with a thickness reduction means in which the thickness direction dimension gradually decreases toward the end side. Therefore, the protrusion shape at the end of the protective film 160 can be reliably relaxed and smoothed, and the protrusion-shaped edge is eliminated and the adhesive layer 101c and the base film 101b are deformed or damaged as in the above embodiment. It is possible to prevent the durability from decreasing.

(2) In the case where an independent first reduced thickness member is provided on the protective film FIG. 13 is a side sectional view of the RFID label T provided with the first reduced thickness member at each end of the protective film 160 in this modification, It is a figure equivalent to FIG. 7 of the said embodiment.

  In FIG. 13, in this modified example, instead of the first reduced thickness portions 160A and 160B having a triangular cross-sectional shape formed at each end of the protective film 160 in the above embodiment, the protective film 160 itself is formed in a rectangular parallelepiped shape, At the end portion, there are provided first reduced thickness members 162A and 162B having a triangular cross-sectional shape whose thickness direction dimension gradually decreases toward the end side.

  Also according to the present modification, by providing the first thickness reducing members 162A and 162B, the thickness reducing means is provided at each end portion of the protective film 160 so that the thickness direction dimension gradually decreases toward the end side. Therefore, the protrusion shape at the end of the protective film 160 can be surely relaxed and smoothed, and the protrusion-shaped edge is eliminated and the adhesive layer 101c and the base film 101b are deformed or damaged as in the above-described embodiment. Can be prevented from decreasing. As the material of the first reduced thickness members 162A and 162B, which are independent members, the same material as that of the protective film 160 may be used, and of course, an adhesive or other filler that does not have an adhesive function is used. May be used.

(3) When the second reduced thickness portion having a triangular cross-sectional shape is formed in the IC circuit portion In the above-described embodiment and the modified examples (1) and (2), the IC circuit portion 151 and the vicinity thereof are covered with a protective film. Although the case where the present invention is applied to the structure described above has been described as an example, the present invention is not limited thereto, and the present invention may be applied to a structure in which such a protective film is not provided. FIG. 14 is a side sectional view of the RFID label T according to a modified example in which a second reduced thickness portion is formed at each end of the IC circuit portion 151 in a structure in which such a protective film is not provided. FIG. It is an equivalent figure.

  In FIG. 14, when the protective film 160 in the above embodiment is not provided and the adhesive layer 101 c is in direct contact with the IC circuit unit 151 and covers the entire RFID circuit element To, the IC circuit unit 151 is It becomes the shape which protrudes with respect to the adhesion layer 101c. Therefore, in this modification, as shown in the drawing, second reduced thickness portions 151A and 151B having triangular cross-sectional shapes are formed at respective end portions of the IC circuit portion 151 so that the thickness direction dimension gradually decreases toward the end side. .

  Also according to this modification, by forming the second reduced thickness portions 151A and 151B, the thickness reduction means is sequentially provided at each end of the IC circuit portion 151 so that the dimension in the thickness direction gradually decreases toward the end side. Therefore, the protrusion shape at the end of the IC circuit portion 151 can be reliably relaxed and smoothed, and the protrusion-shaped edge is eliminated and the adhesive layer 101c and the base film 101b are deformed or damaged as in the above embodiment. It is possible to prevent the durability from decreasing. Although not particularly illustrated, the same effect can be obtained by forming the same second reduced thickness portion at both ends of the IC circuit portion 151 in the tape width direction.

(4) When the second reduced thickness portion having an arcuate cross-sectional shape is formed in the IC circuit portion FIG. 15 is an example in which no protective film is provided as in the modification example of (3) above. FIG. 16 is a side sectional view of the RFID label T in which a second reduced thickness portion having an arcuate sectional shape is formed at each end portion, and is a view corresponding to FIG. 14 of the modified example of (3).

  In FIG. 15, in this modified example, the dimension in the thickness direction is changed to the end in place of the second reduced thickness portions 151A and 151B having a triangular cross-sectional shape formed at each end portion of the IC circuit portion 151 in the modified example of (3). Arc-shaped second reduced thickness portions 151c and 151d having an arc-shaped cross-sectional shape that gradually and gradually decreases toward the side are formed.

  Also according to this modification, by forming the arc-shaped second reduced thickness portions 151c and 151d, a thickness reduction means is provided at each end portion of the IC circuit portion 151 so that the dimension in the thickness direction sequentially decreases toward the end side. Therefore, the protrusion shape at the end of the IC circuit portion 151 can be surely relaxed and smoothed, and the protrusion-shaped edge can be eliminated and the adhesive layer 101c and the base film can be removed as in the modification (3). It can prevent that 101b deform | transforms or is damaged and durability falls.

(5) In the case where an independent second thickness reducing member is provided in the IC circuit portion FIG. 16 is an example in which no protective film is provided as in the modified examples of (3) and (4) above. It is a sectional side view of the RFID label T which provided the 2nd thickness reducing member in the edge part, and is a figure equivalent to Drawing 14 of the modification of the above (3).

  16, in this modified example, instead of the second reduced thickness portions 151A and 151B having a triangular cross-sectional shape formed at each end of the IC circuit portion 151 in the modified example of (3), the IC circuit portion 151 itself is replaced. Formed in a rectangular parallelepiped shape, second reduced thickness members 163A and 163B having triangular cross-sectional shapes are provided at the ends of the rectangular parallelepiped shape.

  Also according to this modified example, by providing the second thickness reducing members 163A and 163B, the thickness reducing means is provided at each end portion of the IC circuit portion 151 so that the thickness direction dimension gradually decreases toward the end side. Therefore, the protrusion shape at the end of the IC circuit portion 151 can be surely relaxed and smoothed, and the protrusion-shaped edge can be eliminated and the adhesive layer 101c and the base film 101b can be removed as in the modified example (3). It is possible to prevent the durability from being deteriorated due to deformation or damage.

(6) When a stepped reduced thickness portion is formed on the protective film FIG. 17 shows that the IC circuit portion 151 and the vicinity thereof are protected film as in the above-described embodiment and the modifications (1) and (2). FIG. 8 is a side sectional view of the RFID label T formed with a step-thickened portion having a stepped shape, which is another modified example of the structure covered with, and is a view corresponding to FIG. 7 of the above embodiment.

  In FIG. 17, in this modified example, the thickness direction dimension is stepped toward the end side instead of the first reduced thickness portions 160 </ b> A and 160 </ b> B having a triangular cross-sectional shape formed at each end portion of the protective film 160 in the above embodiment. Step-thickening portions 164A and 164B having stepped shapes that decrease in number are formed.

  Also according to this modification, by forming the stepped thickness portions 164A and 164B, the thickness of the protective film 160 is provided with thickness reducing means that the thickness direction dimension gradually decreases toward the end side. The protrusion shape at the end of the protective film 160 can be surely relaxed and smoothed, and the adhesive layer 101c and the base film 101b can be prevented from being deformed or damaged and the durability being lowered as in the above embodiment.

  The RFID tag IC circuit holder H having the above-described configuration can be manufactured, for example, according to the following procedure. That is, as described above, the RFID tag IC circuit holder H is configured by arranging the RFID circuit element To including the IC circuit unit 151 and the antennas 152A and 152B on the antenna pattern sheet together with the protective film 160 ( In this embodiment, connection terminals 159A and 159B are also included). As a final step in the manufacturing process of the wireless tag IC circuit holder H, the antennas 152A and 152B are arranged in advance on the protective film 106 in which the IC circuit portion 151 and the connection terminals 159A and 159B are already incorporated. This is a process of joining to the antenna pattern sheet 161.

  FIG. 18 is an explanatory diagram showing the joining step when manufacturing the RFID tag IC circuit holder H. In the joining step shown in FIG. 18, after the protective film 160 provided so as to cover the IC circuit portion 151 is placed on the antenna pattern sheet 161 on which the antennas 152A and 152B are arranged, the existence area of the IC circuit portion 151 is avoided. On the other hand, the pressing member 170 is brought into contact with the protective film 160 so as to pressurize the antenna electrode joining area AA, and is pressed toward the antenna pattern sheet 161, so that it is ensured that the IC circuit unit 151 is adversely affected during pressing. Stepped thickness reducing portions 164A and 164B having a stepped shape in which the thickness direction dimension gradually decreases toward the end side while avoiding the protective film 160, and further, the protective film 160 and the antenna pattern sheet 161 are formed. Can be joined. In this manner, the protrusion shape at the end of the protective film 160 can be relaxed and smoothed without providing a new process.

  In addition, since the step-thickened portions 164A and 164B can be formed at the ends of the protective film 160 by using the pressing member 170 that is usually used to press the protective film 160 against the antenna pattern sheet 161, a new member is prepared. Without any problem, the projection shape at the end of the protective film 160 can be relaxed and smoothed.

  In the joining procedure, for example, the protective film 160 for joining the protective film 160 and the antenna pattern sheet 161 is heated, and thereby a thermoplastic member (ACP) interposed between the protective film 160 and the antenna pattern sheet 161. It is preferable to perform bonding by heating. In this case, the step-thickened portions 164A and 164B can be surely shaped into a desired shape by heating, and the protective film 160 and the antenna pattern sheet 161 can be reliably bonded by heating the ACP. it can.

(7) In the case where bonding is not performed That is, as in the above-described embodiment, printing is performed on the cover film 103 different from the tag tape (base tape) 101 provided with the RFID circuit element To, and these are bonded together. Instead, this is a case where the present invention is applied to a cartridge for a tag label producing apparatus that prints on a cover film provided on a tag tape.

  FIG. 19 is an explanatory diagram for explaining the detailed structure of the cartridge 100 ′ according to this modification, and corresponds to FIG. 3 described above. Components equivalent to those in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted as appropriate.

  In FIG. 19, a cartridge 100 'includes a first roll (tag tape roll) 102' around which a thermal tape 101 '(tag tape) is wound, and a tape that feeds the thermal tape 101' to the outside of the cartridge 100 '. It has a feed roller 107 ′ and a transport turning roll 120 that transports the heat sensitive tape 101 ′ while largely turning the transport direction.

  The first roll 102 'is wound around the reel member 102'a with the transparent heat-sensitive tape 101' in the form of a strip in which a plurality of the RFID tag circuit elements To are formed in the longitudinal direction.

  The heat-sensitive tape 101 'wound around the first roll 102' basically has a four-layer structure (except for the RFID circuit element and its vicinity) in this example (see the partially enlarged view in FIG. 19). A cover film (tag tape substrate layer) 101′b made of PET (polyethylene terephthalate) or the like from the side wound outside (right side in FIG. 19) to the opposite side (left side in FIG. 19) Adhesive layer (fixed adhesive layer) 101′c made of adhesive material, adhesive layer (adhesive material layer for pasting) 101′d made of appropriate adhesive material, release paper (peeling material) 101′e in this order Is configured.

  On the back side (left side in FIG. 19) of the cover film 101′b, there is provided a protective film 160 (protective member) and an IC circuit unit 151 for storing information in an arrangement covered by the adhesive layer 101′c. It has been. The IC circuit portion 151 is located on the back side (left side in FIG. 19) of the protective film 160. On the back side (left side in FIG. 19) of the protective film 160, an antenna pattern sheet 161 (antenna base material) in which two antennas 152A and 152B for transmitting and receiving information are arranged in advance is integrally provided, and an IC circuit is provided. The unit 151 is connected to the antennas 152A and 152B via two connection terminals 159A and 159B, respectively.

  The cover film 101'b and the adhesive layer 101'c are covered on the back side (left side in FIG. 19) so as to enclose the entire RFID circuit element To, and on the front side (right side in FIG. 19) of the cover film 101'b. The surface is a printing surface on which printing is performed by the print head 10. The adhesive layer 101'd is formed so as to cover the whole from the back side (left side in FIG. 19) of the antenna pattern sheet 161, and the release paper 101'e is covered with the cover film 101'b by the adhesive layer 101'd. It is glued to.

  The release paper 101'e can be adhered to the product or the like by the adhesive layer 101'd when the RFID label T finally completed in a label shape is attached to a predetermined product or the like by peeling it off. It is what I did. The RFID circuit element To including the IC circuit 151 and the antenna 152, the protective film 160 provided so as to cover the RFID circuit element To, and the antenna pattern sheet 161 include the adhesive layer 101′c and the adhesive layer 101 ′. It is disposed so as to be inserted between d.

  When the cartridge 100 ′ is mounted on the cartridge holder portion of the tag label producing apparatus 2 and a roller holder (not shown) is moved from the separation position to the contact position, the thermal tape 101 ′ is moved between the print head 10 and the platen roller 108. In addition, it is held between the tape feed roller 107 ′ and the sub roller 109. As the tape feed roller drive shaft 12 is driven by the drive force of the cartridge motor 23 (see FIG. 2), the tape feed roller 107 ', the sub roller 109, and the platen roller 108 rotate in synchronization with each other, and the first roll 102 is rotated. The heat sensitive tape 101 ′ is fed out from ′ and is largely turned in the direction by the transport turning roll 120 and then supplied to the print head 10 side.

  In the print head 10, the plurality of heating elements are energized by the print drive circuit 25 (see FIG. 2), whereby the print is printed on the surface of the cover film 101'b of the thermal tape 101 ', and the tag label tape with print is printed. After being formed as 110 ', it is carried out of the cartridge 100'. It goes without saying that printing using an ink ribbon as in the above-described embodiment may be used.

  After carrying out of the cartridge 100 ′, access (information reading / writing) to the RFID tag information via the antenna 14, conveyance by the sending roller 17, cutting by the cutter 15, etc. are the same as in the above embodiment. Description is omitted.

  FIG. 20 is a side sectional view of the RFID label T in which a first reduced thickness portion is formed at each end of the protective film 160 in this modification, and corresponds to FIG. 7 of the above embodiment.

  In FIG. 20, the protective film 160 is formed with first reduced thickness portions 160A and 160B having a shape in which the dimension in the tape thickness direction gradually decreases toward the end side at both ends in the tape longitudinal direction.

  Also in the cartridge 100 ′ of this modification, substantially the same effect as in the above embodiment is obtained.

  That is, in the RFID circuit element To, the first reduced thickness portions 160A and 160B, which are thickness reducing means, are formed on the end portion of the protective film 160 that covers the IC circuit portion 151 so as to cover the IC circuit portion 151, and the thickness is sequentially increased toward the end side. By making the vertical dimension small, it is possible to surely relax and smooth the protrusion shape that may occur at the end of the protective film 160 as it is. As a result, the adhesive layer 101'c and the cover film 101'b can be deformed or damaged because they can be adhered to the adhesive layer 101'c with a smooth inclined surface at the end thereof to avoid local pressing. It is possible to prevent the durability from decreasing.

  In the above, printing is performed by contacting the cover film 101 ′ b from the outside of the cartridge with the print head 10. However, the present invention is not limited to this, and the ink ribbon 105 is used for the cartridge as in the above-described embodiment. Printing may be performed from the inside (so-called receptor type, but not a specular character as will be described later). FIG. 21 is an explanatory view for explaining the detailed structure of the cartridge 100 ″ in such a modification, and corresponds to FIG. 19 described above. The same parts as those in FIG. 3, FIG. Reference numerals are given, and explanations are omitted as appropriate.

  In FIG. 21, a cartridge 100 ″ has a first roll (tag tape roll) 102 ″ around which a base tape 101 ″ (tag tape) is wound, and this base tape 101 ″ is tape-fed outwardly of the cartridge 100 ″.
