  However, in the conventional IC tag and the management system using the conventional IC tag, communication of information stored in the storage unit of the IC tag is performed between the IC tag and the data processing device via the reader / writer device. Because it is necessary, it is necessary to handle the IC tag under strict management, or it is necessary to make the system configuration in which the data processing device of the management system can be used only by sharable information. The convenience of the management system itself may be impaired.

  In addition, in a conventional IC tag and a management system using a conventional IC tag, information is read from a storage unit provided in the IC tag, and information is input (written) to the storage unit of the IC tag. Updates and corrections can be performed relatively easily, and information stored in the IC tag storage unit can be easily managed. On the other hand, leakage of information stored in the IC tag storage unit, data alteration, etc. There was also a problem that accompanied the danger of.

  Therefore, in the conventional IC tag and the management system using the conventional IC tag, the information stored in the IC tag storage unit itself is encrypted, or the secret information is stored and managed only on the data processing apparatus side. However, there is a problem in that the processing work becomes complicated.

  The present invention has been made in view of the above problems, and by making the IC tag separable, access to data (that is, information) stored in the storage unit of the IC tag is predetermined. An object is to provide an IC tag that is physically restricted except for the state, making it difficult to tamper with, making it easy to visually check the restricted state, and simple processing.

  It is another object of the present invention to provide a merchandise distribution management system using this physically separable IC tag.

  The tag of the present invention has a main body structure in which at least one tag separation part is detachably mounted on a tag base part serving as a base, and one tag separation part is constituted by a remaining part including the tag base part In the initial state of being attached to the main body, the tag main body constituted by the remaining portion including the one tag separating portion and the tag base has the first function, and after the one tag separating portion is separated. The tag main body constituted by the remaining part including the tag base is changed to the second function restricted or released from the first function described above.

  In addition, the management system of the present invention has a tag body in which a plurality of tag separation units are detachably attached to a tag base having a control unit that controls writing / reading to / from a storage unit, and the tag separation unit Each time separation is performed, a tag that is restricted from being written by the control unit to the storage area corresponding to the separated tag separation unit of the storage unit is used, and this tag is attached to the management target to manage the management target. For each stage, the tag separation unit corresponding to the management stage is attached to the tag main body constituted by the remaining part including the tag base, and the unique data in the management stage corresponds to the tag separation part. After writing to the storage area, when shifting from the management stage to the next management stage, the tag separation unit corresponding to the management stage is moved from the tag body configured by the remaining part including the tag base. Characterized in that it away.

  According to the present invention, the tag is constituted by a main body structure in which at least one tag separation part is detachably mounted on a base tag base part, and the tag separation part is constituted by a remaining part including the tag base part. By adopting a structure that can be separated from the tag body, it is possible to change the function of the tag body constituted by the remaining part including the tag base after the tag separation part is separated from that before separation. It is possible to provide a tag that is extremely difficult to tamper with data later.

  Specifically, in the initial state where the tag separation unit is mounted on the tag main body constituted by the remaining part including the tag base, for example, basic information such as the manufacturing number of the article to be managed, individual characteristic data, etc. A tag main body that stores confidential data in one or a plurality of storage areas corresponding to the tag separation unit provided in the tag, and on which the tag separation unit is configured by a remaining portion including a tag base. By separating from the above, it is possible to make a state in which one or a plurality of storage areas corresponding to the tag separation unit can be read only and can only be read, and further cannot be read. It is easy to prevent tampering of confidential information such as individual characteristic data.

  In addition, in a tag having a main body structure in which a plurality of tag separation parts are detachably mounted on a tag base part serving as a base, a different color scheme or pattern is applied to the exposed surface of each tag separation part. As a result, the functional state of the current tag can be easily identified, and accidents such as forgetting separation can be prevented. Furthermore, when the tag employs a main body structure in which a plurality of tag separation portions are detachably stacked on the tag base portion, the color or pattern applied to the exposed surface of the uppermost tag separation portion is the remainder. Since it becomes dominant with respect to the color and the pattern given to the surface of the tag separation part, the distinctiveness about the functional state of the current tag is further improved.

  As described above, according to the tag and the management system of the present invention, the function of the tag main body constituted by the remaining portion including the tag base is changed due to the change in the physical state of the tag due to the separation of the tag separation unit. It is possible to provide a tag and a management system having various security functions. Therefore, regardless of the effective range and confidentiality of the data, it becomes possible to handle the management according to the management stage of the management target with the same tag, and the reliability of the data is increased.

  The storage unit 14-1 provided in the first tag separation unit 10-1 and the storage unit 14-2 provided in the second tag separation unit 10-2 are also stored in the tag base unit 10-0 described above. Similarly to the area M0, each of the storage areas M1 and M2 can be functionally divided by corresponding to the remaining tag components 10-0, 10-2, 10-0 and 10-1. However, for the sake of easy understanding in the description of the present embodiment, an undivided configuration will be described as an example.

  In FIG. 2, the separation states of the tag separation units 10-1 and 10-2 with respect to the tag base 10-0 in the IC tag 1 are indicated by boundary lines 21, 22 and 23. Here, the boundary lines 21 and 22 correspond to the first joint surface 11-1 and the second joint surface 11-2 described above, respectively.

  The boundary line 23 is formed by joining the tag base portion 10-0 with the first and second tag separating portions 10-1 and 10-2, and the tag main body 10 by the three integrated tag component portions 10-1 to 10-2. Is an initial state of the IC tag 1 configured. In the figure, broken line arrows extending in a direction perpendicular to the boundary lines 21, 22, and 23 indicate storage areas M0 (M00, M01, M02), M1, and M2 of the storage units 14-0 to 14-2, respectively. Shows access restrictions. In this initial state, the dashed arrows extending from the boundary line 23 to the tag constituting units 10-0, 10-1, and 10-2 are the storage areas of the storage units 14-0 to 14-2 in the initial state. The permitted access to M0 (M00), M1, and M2 is shown.

  In the initial state, the boundary line 22 separates only the second tag separation unit 10-2 from the tag base unit 10-0 and the first tag separation unit 10-1, and the tag base unit 10 in which the tag main body 10 is joined to each other. The access restrictions in the 1st isolation | separation state of the IC tag 1 comprised only from -0 and the 1st tag isolation | separation part 10-1 are shown.

  In the second separation state, a dotted arrow extending from the boundary line 21 to the tag base 10-0 as a starting point or an end point indicates the storage area M0 (M00, M01, M02) of the storage unit 14-0 in the second separation state. Indicates allowed access to.

  FIG. 3 is a table summarizing access restrictions regarding the storage units provided in the tag base and the tag separation unit constituting the IC tag described in FIG.

  In the initial state of the IC tag 1 in which the first and second tag separation units 10-1 and 10-2 are stacked and integrally joined to the tag base 10-0, the storage unit 14 of the tag base 10-0. Storage area M00 formed in -0, storage area M1 formed in storage section 14-1 of the first tag separation section 10-1, storage in the storage section 14-2 of the second tag separation section 10-2 The area M2 can be accessed (written / read) from the input / output interface unit 12 via the control unit 13.

  Therefore, in the initial state, the same data common to each of the plurality of areas and data C1, C2, and L1 of different items can be input to each of the storage areas M01, M1, and M2. However, the storage areas M01 and M02 in the storage unit 14-0 of the tag base unit 10-0 cannot input / output data (read / write).

  Next, the second tag separation unit 10-2 is peeled (separated), and the tag body 10 is in a state where only the tag base unit 10-0 and the first tag separation unit 10-1 are stacked. In the separated state, the second tag separation unit 10-2 is separated, so that the storage unit 14-2 is disconnected from the control unit 13, and data input / output (read / write) to / from the storage area M2 is physically performed. It becomes impossible. Furthermore, in the present embodiment, writing to the storage area M00 of the storage unit 14-0 by the control unit 13 is prohibited, and only reading is possible. Further, the control unit 13 can newly input / output (read / write) data C3 and C4 with respect to the storage areas M01 and M02 in the storage unit 14-0 of the tag base 10-0. In the present embodiment, in this first separation state, input / output (reading) of data L2 to / from the storage area M1 of the storage unit 14-1 in the first tag separation unit 10-1 by the control unit 13 is performed. / Write) is still possible.

One storage area M1 can input / output (read / write) the same common data and different items of data C3, C4, L2. Further, only the data C1 written in the initial state can be read from the storage area M00 in the storage unit 14-0 of the tag base unit 10-0.

  Next, in the second separation state of the IC tag 1 in which the first tag separation unit 10-1 is peeled and the tag body 10 is only the tag base 10-0, the first tag separation unit 10-1 is As a result of separation or separation, the storage unit 14-1 is disconnected from the control unit 13, and data input / output (read / write) to the storage area M 1 becomes physically impossible. Then, writing of data to the storage area M01 of the storage unit 14-0 by the control unit 13 is prohibited, and only the reading of the data C3 written in the first separation state is performed as in the storage area M00 of the storage unit 14-0. Is possible.

  Therefore, in the second separation state, data L3 can be input / output (read / write) only in the storage area M02 in the storage unit 14-0 of the tag base unit 10-0 that can still be accessed. Further, only the data C1 and C3 written in the initial state and the first separation state can be read from the storage areas M00 and M01 in the storage unit 14-0 of the tag base unit 10-0.

  According to the IC tag 1 according to the present embodiment, the IC tag 1 is configured by joining the plurality of tag separating units 10-1 to 10-n to the tag base unit 10-0 so as to be separable and integrally, Further, since the corresponding storage portions 14-0 to 14-n are formed in the tag base portion 10-0 and the tag separation portions 10-1 to 10-n, one tag separation portion 10-x is connected to the tag base portion 10-. By separating the tag main body 10 composed of the remaining portion including 0, the data (information) itself stored in the storage unit 14-x formed in the separated tag separation unit 10-x The IC tag 1 can be brought into a state where it cannot physically exist.

  Furthermore, according to the IC tag 1 according to the present embodiment, the tag base portion 10 constituting the tag main body 10 constituted by the remaining portion including the tag base portion 10-0 by separating one tag separation portion 10-x. -0 and tag separators 10-1 to 10-x-1 access to the memory areas M-1 to M-x-1 in the storage units 14-0 to 14-x-1, respectively. It can be physically restricted or unrestricted in connection with the separation of the part 10-x. The access restriction is not limited to the embodiment shown in FIGS. 2 and 3 and can be set as appropriate according to the purpose.

  As a result, the IC tag 1 according to the present embodiment can improve the confidentiality of data among persons involved in the IC tag 1 and can also make it difficult to tamper with the data.

  In addition, the work for concealment and prevention of tampering is only required to physically separate the tag separation unit 10-x of the IC tag 1 from the tag body 10 constituted by the remaining portion including the tag base 10-0. The processing operation becomes easy, and the current restriction state of the IC tag 1 can be easily confirmed visually.

Next, another embodiment of the IC tag of the present invention will be described.
In the above-described embodiment, the storage units 14-0, 14-1, and 14-2 correspond to the tag base unit 10-0, the first tag separation unit 10-1, and the second tag separation unit 10-2, respectively.

  Also in the present embodiment, the storage unit 14 is recognized by recognizing the presence or absence of each of the first tag separation unit 10-1 and the second tag separation unit 10-2 joined in a stacked state with respect to the tag base 10-0. By applying access restrictions to the storage areas M30 and M31 and the storage areas M32 and M33 corresponding to the first and second tag separation units 10-1 and 10-2, the same operation and effect can be achieved. It becomes possible. In this case, as an access restriction method, for example, the storage area of the storage unit 14-3 as described later based on the separation of the first tag separation unit 10-1 and the second tag separation unit 10-2. For example, physical disconnection of signal line connection to M30 and M31 and storage areas M32 and M33 can be used.

  According to the IC tag 1 of the present embodiment, although the access is restricted, the storage areas M31 and M33 corresponding to the first and second tag separation units 10-1 and 10-2 are the first and second storages. There is a problem that even after the tag separation units 10-1 and 10-2 are separated, they move together with the tag base unit 10-0 and remain as the tag main body 10 until the end, but the first and second tag separation units 10- It is not necessary to form the storage units 14-1 and 14-2 in 1 and 10-2, and the storage units 14-0 to 14-2 respectively corresponding to the tag constituent units 10-0, 10-1, and 10-2. Can be formed on the same tag component (that is, the tag base 10-0) and can be realized at low cost.

  Further, storage units 14-0 to 14-2 respectively corresponding to the tag base 10-0 and the first and second tag separation units 10-1 and 10-2 according to the present embodiment are provided on the tag base 10-0. As another example of how to limit access in the formed IC doug 1, if necessary, when the first and second tag separation units 10-1 and 10-2 are peeled off, the storage unit 14- It is also possible to delete the data stored in the three storage areas M31 and M33.

  Next, an embodiment of a management system using the IC doug 1 configured as described above will be described by taking as an example the case where it is applied to merchandise distribution management.

  The tag body structure IC tag 1 in which the first and second tag separating portions 10-1 and 10-2 are laminated on the tag base portion 10-0 as described in FIGS. According to this, by attaching the IC tag 1 to the product to be managed, for example, the first tag separation unit every time the article moves along the distribution route and the manager changes according to the distribution stage. Management of the entire distribution stage by using the tag body 10 constituted by the remaining part including the tag base 10-0 as the IC tag 1 while separating the 10-1 and the second tag separation unit 10-2. It is possible to separately manage data that is to be shared among administrators, data that is shared only between some managers, and data that is hidden from other managers.

  FIG. 5 is a diagram showing an example of the state of the IC tag in the distribution stage, taking as an example the case where the IC tag is applied to the merchandise distribution management system.

  In FIG. 5, the IC tag 1 as described in FIG. 1, FIG. 2, or FIG. 4 is attached, for example, by being attached to a product (article) 200 to be managed, and its distribution stages A, B, C This represents a case of sequentially moving between the managers a, b, and c through such a route.

  For example, in the distribution stage A, the manager a sends information C1 (see FIG. 3) to be shared to the manager b in the stage B and the manager c in the stage C to the area M00 (see FIG. 2) or the area M30 (see FIG. 2). Write to FIG.

  On the other hand, if there is secret information L1 (see FIG. 3) that the manager a wants to keep secret from the manager b in the stage B and the manager c in the stage C, the manager a or the area M2 (see FIG. 2) Write to M31 (see FIG. 4). Further, the administrator a shares information C2 (see FIG. 3) that the administrator b in the stage B shares with the manager b in the stage B but wants to keep secret from the manager c in the stage C (see FIG. 2) or the area M33 (see FIG. 4). Write).

  As a result, the administrator a, when shipping from stage A to stage B, replaces the second tag separation section 10-2 of the IC tag 1 with the tag base section 10-0 and the first tag separation section 10-1. The first tag separation unit 10-1, the second tag separation unit 10-2, and the tag base unit 10-0 are integrally joined by peeling off from the remaining tag body 10 made of The data L1 stored in the region M2 or the region M31 that cannot be read / written unless the tag body 10 is in the state cannot be read / written after the stage B.

  Next, in the distribution stage B, the administrator b has the tag main body 10 after the second tag separation unit 10-1 is peeled off as a joined body of the first tag separation unit 10-1 and the tag base unit 10-0. The administrator b receives information from the administrator a by reading the data C1 and C2 stored in the areas M00 and M1 (see FIG. 2) or the areas M30 and M33 (see FIG. 4). Can be shared. However, since the administrator b cannot write data in the area M00 or the area M30, the information C1 stored in the area M00 or the area M30 cannot be modified.

  Then, the administrator b writes information C3 and C4 (see FIG. 3) that he / she wants to share with the administrator c at the next stage C in the areas M01 and M02 (see FIG. 2) or the areas M32 and M34 (see FIG. 4). . In this writing, the administrator b writes the information C3 prohibiting the data change by the administrator c into the area M01 or the area M32, and writes the information C4 allowing the data change into the area M02 or M34.

  On the other hand, if there is secret information L2 (see FIG. 3) that the manager b wants to keep secret from the manager c in the stage C, the manager b is in the area M1 (see FIG. 2) or the area M33 (see FIG. 4). Write.

  Thereby, the administrator b peels off the first tag separation unit 10-1 of the IC tag 1 from the remaining tag main body 10 consisting only of the tag base 10-0 at the time of shipment from the stage B to the stage C. Thus, the data L2 stored in the region M1 or the region M33 that cannot be read / written unless the original tag body 10 is integrally joined with the second tag separation unit 10-2 and the tag base 10-0. Cannot be read / written in stage C.

  Next, in the distribution stage C, the administrator c receives the IC tag 1 in which the tag body 10 is composed only of the tag base 10-0 from which the first tag separation unit 10-1 has been peeled off, and enters the area M00 or the area M30. By reading the stored data C1, the administrator c can share the information C1 from the administrator a with the administrator b. However, since the administrator c cannot write data to the area M00 or the area M30 like the administrator b, the information C1 stored in the area M00 or M30 cannot be modified.

  Further, the administrator c reads out the data C3 stored in the areas M01 and M02 or the areas M32 and M34 of the IC tag 1 including only the tag base 10-0, so that the administrator c obtains information C3 from the administrator b. Can be shared. Also in this case, since the administrator c cannot write data in the area M01 or the area M32, the information C3 stored in the area M01 or the area M32 cannot be modified. Then, the administrator c can write in the area M02 or the area M34 (see FIG. 4) if there is information L3 (see FIG. 3) that only the administrator c needs.

  As described above, according to the merchandise distribution management system to which the IC tag 1 of the present embodiment is applied, the data C1 that is desired to be shared as a whole at each stage, and is shared only between some managers before or after a certain stage. Data C2, C3, C4, data L1, L2, L3, etc. to be kept secret can be managed separately.

  For example, the manufacturer a is internal information about the product 200 that the material supplier, purchase price, performance inspection information, etc. do not want to be disclosed to the outside. In the area M2 or the area M31 corresponding to the first tag separation unit 10-1 in the storage unit 14, the secret information L1 that is preferably held individually in terms of management efficiency when there is the product 200 is stored in the area M2 or the area M31 corresponding to the first tag separation unit 10-1. Store and manage. In addition, the manufacturer C stores information C1 which is disclosed to the outside such as basic data C1 regarding the product 200 but is not desired to be modified by the store b or the consumer c in the area M00 or the area M30 in the storage unit 14. Can manage. Further, information C2 that is not required to be disclosed to the consumer c, such as a sales handling method, can be stored and managed in the area M1 or the area M33 in the storage unit 14.

  In addition, when the product 200 is shipped, the manufacturer a replaces the second tag separation unit 10-2 with the remaining tag main body 10 including the joined body of the first tag separation unit 10-1 and the tag base unit 10-0. After peeling off and separating, it is shipped. Accordingly, the area M2 or the area M31 in which the secret information L1 is stored is substantially eliminated from the remaining tag main body 10 attached to the product 200. On the other hand, the basic data C1 related to the product 200 stored in the region M00 or the region M30 of the tag base 10-0 is restricted so that it cannot be rewritten or added.

  Next, in the store b that receives the product 200, the basic data C1 related to the product 200 stored in the area M00 or the area M30 in the storage unit 14, the sales handling method stored in the area M1 or the area M33, and the like. Such information C2 can be confirmed.

  In addition, in the store b, internal information L2 such as a purchase price and sales price management information is written and managed in the area M1 or the area M33 corresponding to the first tag separation unit 10-1 in the storage unit 14. Can do. Further, when selling the product 200 to the consumer c, additional data C3 that is not desired to be rewritten by the consumer c such as a sales date is stored in the area M01 or the area M32 corresponding to the tag base 10-0 in the storage unit 14. In addition to being able to be input and managed, contact information C4 that may be deleted and modified by the consumer c such as fixed holiday guidance can be input and managed in the area M02 or the area M34. The internal information L2 written in the area M1 or the area M33 by the store b may be added to the information C2 written by the manufacturer a or may be overwritten.

  In addition, when the consumer c purchases the product 200, the store b peels off the first tag separation unit 10-1 in which the internal information L2 of the store b is stored correspondingly. After the separation, the product 200 to which the remaining tag body 10 consisting only of the tag base 10-0 is attached is delivered to the consumer c. Thereby, the area M1 or the area M33 in the storage unit 14 in which the secret information L2 is stored is substantially eliminated from the remaining tag main body 10 attached to the product 200. On the other hand, the additional data C3 that is not desired to be rewritten by the consumer c, such as the sales date, stored in the area M01 or the area M32 in the storage unit 14 is restricted so that it cannot be rewritten or appended.

  The consumer c, from the storage unit 14 of the tag 1 in which the second tag separation unit 10-2 and the first tag separation unit 10-1 are peeled off and the tag main body 10 is only the tag base 10-0, Basic data C1 related to the product 200 stored in the region M00 or the region M30, additional data C3 such as sales date stored in the region M01 or the region M32, fixed holiday guidance stored in the region M00 or the region M30, etc. The contact information C4 can be confirmed.

  Further, the consumer c writes optional content L3 regarding the purchase of the product 200 in the area M02 or M34 corresponding to the tag base 10-0 assigned to the consumer c in the storage unit 14. Can be managed.

  In the above-described embodiment, for example, the area M02 or M34 in the storage unit 14 is configured to be readable / writable only by the manufacturer a and the consumer c, so that the stored information is stored in the store b. Can be concealed, and only the consumer c is configured to be readable / writable, so that the manufacturer a and the store b at a higher stage cannot read / write in the area M02 or M34. It is also possible.

  In this way, by using the IC tag 1 whose function changes corresponding to the separation of the tag separation units 10-2 and 10-1 in the management system, the confidentiality of information is improved, and later data A management system that is extremely difficult to tamper with can be provided.

  FIG. 6 is an explanatory diagram of a more preferable example of the IC doug when the IC doug of the embodiment described in FIG. 1 and FIG. 2 or FIG. 4 is applied to a merchandise distribution management system.

  As described above, the configuration of the IC doug 1 according to the present embodiment is such that the plurality of tag components 10-0, 10-1, and 10-2 are integrally joined in a separable manner. The functions of the IC tag 1 can be changed by sequentially peeling the stacked tag separating units 10-1 and 10-2 to handle shared data and limited secret data. In addition, there is no possibility of human error such as secret data leaking or shared data not being shared due to forgetting to peel off tag separation units 10-1 and 10-2, overlapping peeling, or the like.

  Therefore, as shown in FIG. 6, the IC doug 1 according to the present embodiment has the patterns and color schemes of the surfaces of the boundary lines 21, 22, and 23 of the tag components 10-0, 10-1, and 10-2. By making it different, the visual recognizability of the peeled state (separated state and distribution stage) of the current IC doug 1 is improved. As a result, the recognition of the tag component 10-x in the uppermost layer becomes clear at a glance, and it becomes possible to prevent leakage of secret data due to human error in handling the IC tag 1 due to forgetting to peel off or overlapping peeling. ing.

  Next, a specific separation structure of the tag components 10-0, 10-1, and 10-2 of the IC tag 1 as described in FIG. 1 and FIG. 2 or FIG. 4 will be described with reference to the drawings.

  FIG. 7 is a first example of the separation structure of the tag separation unit in the IC tag of the present embodiment.

  In FIG. 7, the IC tag 1 is a sheet-like first flexible sheet constituting a second tag component on a tag base 10-0 constituting a thin plate-like first tag component. The tag separating portion 10-1 and the third tag constituting portion of the second flexible sheet-like second tag separating portion 10-2 are sequentially joined and overlapped.

  The first tag separation unit 10-1 and the second tag separation unit 10-2 are separated from the separated portions 10-1p, 10-2p and the non-separated portions along a wavy broken line 35 shown by a broken line in the drawing. The plane is divided into 10-1q and 10-2q. The other side surface (back surface) of the non-separation portion 10-2q of the second tag separation portion 10-2 is integrated with one side surface (front surface) of the non-separation portion 10-1q of the first tag separation portion 10-1. In addition, the other side surface (back surface) of the non-separation portion 10-1q of the first tag separation unit 10-1 is integrally bonded onto one side surface (front surface) of the tag base 10-0. ing. As a result, the non-separation portion 10-2q of the second tag separation unit 10-2 further includes the first tag separation unit 10-1 with respect to the non-separation portion 10-1q of the first tag separation unit 10-1. The non-separating portion 10-1q is integrally joined to the tag base portion 10-0 so as not to be separated (peeled).

  On the other hand, the central convex portion 10-2pp defined by the wavy break line 35 on the other side surface (back surface) of the separation portion 10-2p of the second tag separation portion 10-2 and both side edge portions 10 thereof. -2p1 and 10-2p2 are the central convex portion 10-1pp on one side surface (surface) of the separation portion 10-1p of the first tag separation portion 10-1 and its both side edge portions 10-1p1, 10-1p2 Further, the other side surface (back surface) of the separation portion 10-1p of the first tag separation portion 10-1 is a convex portion 10-1pp at the center and both side edge portions 10-1p1, 10-1p2 is partially attached to the tag base 10-0. As a result, by lifting the non-sticking portion in the separation portion 10-2p of the second tag separation portion 10-2, the separation portion 10-2p is separated from the non-separation portion 10-2q along the broken line 35. It is separated and is configured to be peelable from the separation portion 10-1p of the first tag separation section 10-1. Similarly, by pulling up the non-sticking part in the separation part 10-1p of the first tag separation part 10-1, the separation part 10-1p is moved along the broken line 35 to the non-separation part 10-1q. Is separated from the tag base 10-0.

  The non-separated portions 10-2q and 10-1q of the second tag separating portion 10-2 and the first tag separating portion 10-1 are separated by a wavy broken line 35-2p. , 10-1p, the signal line 32 and the signal line 31 extending across the convex portions 10-2pp, 10-1pp are formed, and both ends of each of the signal lines 32, 31 are the first tag components shown in FIG. The signal is connected to the control unit 13 of the IC chip 19 formed in 10-2. As a result, a closed circuit loop 42 having a portion that crosses the convex portion 10-2pp with respect to the IC chip 19 by the signal line 32 is formed in the second tag separation unit 10-2, and the first tag In the separation part 10-1, a closed circuit loop 41 having a part that crosses the convex part 10-1pp with respect to the IC chip 19 by the signal line 31 is formed.
