Description

  The present invention relates to an identification tag, and more particularly to an identification tag for transmitting an identification signal.

  2. Description of the Related Art Conventionally, as a method of automatically identifying and automatically handling an article, for example, a method of using an identification tag capable of wireless communication such as an IC tag for storage of a document file, inventory management of goods, and a tag for handling articles Is presented and actually used. Compared with an identification tag on which an optically readable identification code such as a bar code is mounted, the identification tag capable of wireless communication does not need to be exposed on the surface of the article, so the appearance is not impaired. Since the orientation of the identification tag with respect to the reader is free, there is an advantage that it is not necessary to adjust the orientation of the article at the time of reading. In addition, it has also been proposed to use an identification tag capable of wireless communication for identifying / instructing an operation in addition to identifying an object (Patent Document 1).

When there are a plurality of these identification tags, there may be a case where communication is performed by approaching one communication device to be read one by one in sequence, but in an environment where a plurality of identification tags are placed in one place, A method in which two communicators communicate at the same time has also been proposed (Patent Documents 2, 3, and 4). For example, a container that collects a plurality of articles is handled as it is without performing an operation of separately reading identification tags. It becomes possible.
JP 2000-187715 A Special table 2001-523631 Special table 2001-511276 JP 2003-271912 A

  In the above conventional method, one identification tag corresponds to one article or operation. However, when considering a case where a sheet or tape on which a large number of identification tags are arranged is cut into an arbitrary size, a plurality of identification tags responding to reading are placed on a common cut piece. It is necessary to determine whether it is on a different cut piece. Although this situation has not been discussed so far, for example, a plurality of identification tags are provided in advance on a sealing tape when packing, and cut at an appropriate length according to the size of the packing. The situation to be used can be considered.

  In this case, a plurality of identification tags may be attached to one package. In order to handle the package by a conventional method, the response of the identification tag is individually read by the communication device after packing, and the plurality of allocated identification codes are stored in the database when corresponding to one package. And whenever it uses in a conveyance and distribution process, this database is accessed and an identification code is collated.

  For example, considering that a long sealing tape carrying a plurality of identification tags is cut into an appropriate length and used for packaging, a plurality of identification tags are attached to one package in this case. In such a case, a plurality of such packages are put in a container and transported. In other words, in order to cut a single sealing tape into several pieces for packaging, a plurality of identification tags arranged continuously on a long sealing tape are divided into several groups and separated. Will be affixed to the package.

  When attempting to read the response of the identification tag with the communication device during the transportation process, there are a plurality of identification tags because there are a plurality of identification tags in the container. At this time, in order to determine the number of packages, access to a database created at the time of packing is required. This is because the information about the cutting position of the sealing tape cannot be read from the response from inside the container, and exists only in the database created at the time of packing. In the distribution process, a plurality of packages sent from the packaging source are often sent to different delivery destinations. In this case, communication to the database occurs in many distribution stages, and the communication load with the database increases. In order to avoid this, when trying to create a unique database in the intermediate stage of transportation, it is necessary to take out and pack from the container in order to read out the packed items one by one with the communication device at the time of database creation. It takes. In addition, since the database is sequentially accessed when the response of the identification tag is received, the reading device becomes complicated.

  The present invention has been made in view of the above points, and the object of the present invention is to use an identification tag such as a sheet or tape on which a large number of identification tags are arranged and cut into an arbitrary size. Another object of the present invention is to provide an identification tag that can easily distinguish an identification tag placed on one cut piece from an identification tag placed on another cut piece.

  In order to solve the above-mentioned problem, in an identification tag having a plurality of identification tags mounted on a base material, information separated from a signal transmitted from the identification tag is included when adjacent identification tags are separated. I was going to be.

  Specifically, the first identification tag of the present invention is an identification tag for transmitting an identification signal, and a plurality of main body portions for transmitting the identification signal, and a base material on which the main body portion is mounted on a mounting surface. The main body unit includes an identification signal transmitting unit, and a cutting detection line that extends from the identification signal transmitting unit and detects the presence or absence of its own cutting. On the mounting surface of the base material part, the cutting detection line of the one main body part is connected to the identification signal transmitting part of the one main body part from the identification signal transmitting part of another main body part adjacent to the one main body part. When viewed from a direction substantially perpendicular to the direction of heading, it overlaps with the other main body, the identification signal includes a unique code unique to each main body, and the cut detection line is When cut, it is configured to further include a cut code. Here, the presence / absence of the cutting itself means whether or not the cutting detection line itself is cut. In addition, the fact that the cut detection line of one main body part overlaps with another main body part means that it appears to overlap when viewed from the aforementioned direction along the mounting surface rather than physically overlapping. That is.

  A second identification tag of the present invention is an identification tag for transmitting an identification signal, and includes a plurality of main body portions for transmitting the identification signal, and a base material portion on which the main body portion is mounted. A disconnection detection line extending from the identification signal transmission unit and detecting the presence or absence of the disconnection of the identification signal transmission unit. Is located above or below the identification signal transmitter of another main body adjacent to the one main body, and the identification signal includes a unique code unique to each main body. In addition, when the cutting detection line is cut, a cutting code is further included. An inclusion may exist between the part of the cut detection line of the one main body and the identification signal transmitter of the other main body.

  A third identification tag of the present invention is an identification tag for transmitting an identification signal, and includes a plurality of main body portions for transmitting the identification signal and a base material portion on which the main body portion is mounted, and the plurality of main bodies. One body part of the parts has a cutting detection line for detecting that at least one of the other body parts adjacent to the one body part is cut off, and the identification signal is Each of the main body portions includes a unique code, and when it is detected that the cut detection line is cut off, a cut code is further included.

  Since it has the configuration as described above, it is detected that the cutting detection line is separated between adjacent main body parts, and an identification signal including information indicating the separation is transmitted, and the identification tag is cut. It is possible to reliably determine whether or not

  By using the identification tag of the present invention, when using a sheet or tape in which a large number of main body parts are arranged and cut to an arbitrary size, a plurality of main body parts responding to reading are cut in the same way It is easy to determine whether it is on a piece or on a different piece. As a result, the amount of communication with the database for determination can be reduced and the reader can be simplified, and the use of an identification tag having a plurality of main body parts can be facilitated.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following drawings, components having substantially the same function are denoted by the same reference numerals for the sake of brevity. In the following, the present invention may be described with examples, but the present invention is not limited to the examples described below.

(Embodiment 1)
As shown in FIG. 1A, the identification tag of the first embodiment is a one-dimensional structure in which a plurality of main body portions 10a, 10a,... That are identification units are mounted on a tape-like base material portion (not shown). (On a straight line). Heretofore, what has been described as an identification tag is referred to as a main body 10a, 10a,.

  The body portions 10a, 10a,... Have identification signal transmitters 11a, 11a,... That transmit identification signals, first cut detection lines 12a, 12a,..., And second cut detection lines 13a, 13a,. It has. The identification signal transmitters 11a, 11a,... Are circuits that have a general wireless communication identification tag (IC tag) such as a circuit that records a unique identification signal for each main body 10a, 10a,. A processing circuit including The first cut detection line 12a is a line that extends from one identification signal transmitter 11a to the vicinity of another adjacent identification signal transmitter 11a. As shown in FIG. 1B, the first cut detection line 12a has one conductive line extending from one identification signal transmitter 11a and adjacent to another identification signal transmitter 11a. A U-turn is made in the very vicinity of and the structure returns to the original identification signal transmitter 11a again. The second cut detection lines 13a, 13a,... Have the same configuration and structure.

  The main body portions 10a, 10a,... Transmit different identification signals, and these identification signals include unique codes unique to the main body portions 10a, 10a,.

  Here, when the base material portion is cut between two adjacent main body portions 10a and 10a (one main body portion and another main body portion), and the two adjacent main body portions 10a and 10a are separated, The first cut detection line 12a of the main body part 10a (one main body part) is also cut, and conduction between both ends of the conductive line connected to the identification signal transmission part 11a shown in FIG. Thereby, it is determined by the identification signal transmitter 11a of the main body 10a (one main body) that the first cut detection line 12a itself has been cut. Further, the second cut detection line 13a of another adjacent main body 10a is also cut, and the cut is similarly detected by the identification signal transmitter 11a of the main body 10a. In this case, the identification signal transmitted from the main body 10a (one main body) has a cut code in addition to the above-described unique code. In addition, the identification signal transmitted from another main body 10a also has another cut code in addition to the above-described unique code.

  The outline of the identification tag of this embodiment is as described above, and will be described in more detail below.

  In FIG. 1, the first cut detection lines 12a, 12a,... Extend rightward from the main body portions 10a, 10a,..., And the second cut detection lines 13a, 13a,. That is, in one main body portion 10a, the first cutting detection line 12a of the main body portion 10a is adjacent to the second cutting detection line 13a of another main body portion 10a and the identification signal transmitting portions 11a of both main body portions 10a and 10a. , 11a are arranged substantially in parallel. These aligned portions are substantially perpendicular to the direction from one identification signal transmission unit 11a to another identification signal transmission unit 11a on the mounting surface of the base material unit on which the main body units 10a, 10a,. When viewed from the direction, they appear to overlap. Therefore, when the base material part is cut between the two identification signal transmission units 11a and 11a and the two identification signal transmission units 11a and 11a are separated, the first detection line 12a of the main body unit 10a is different from the first detection line 12a. The second cut detection line 13a of the main body 10a is also cut, and the fact that it has been cut is included in the identification signal. With such a configuration, the presence / absence of cutting and the cutting location can be determined by receiving and analyzing the identification signals transmitted from the main body portions 10a and 10a. Note that “substantially parallel” or “substantially perpendicular” does not mean parallel or vertical in a mathematically strict sense, but means a width of about ± 8 °, and ± 5 A width of ° is more preferred. The apparent overlap between the first cut detection line 12a of one main body 10a and the second cut detection line 13a of another main body 10a only needs to exist at least partially. If there is no overlap, when the base material portion is cut at a portion where there is no overlap, none of the cut detection lines 12a and 13a is cut and the cut cannot be detected, but some of the overlap is apparent. If it exists, the cutting | disconnection detection can be performed reliably.

  Each of the identification signal transmitters 11a, 11a,... Includes a circuit for wireless communication having the configuration of the block diagram shown in FIG.

  This circuit configuration includes an antenna block, a rectifier circuit, a power supply circuit, a signal processing block, and a recording block. Like a general IC tag, the power supply circuit supplies power to the signal processing block and the storage block using the energy supplied from the antenna block via the rectifier circuit as a power source. The signal processing block includes a clock extraction circuit, a reset circuit, a counter, a digital control circuit, and a modulation circuit. The recording block includes an address decoder, a recording unit, and a sensor unit (cut detection unit).

  In the antenna block, the antenna circuit and the resonance circuit may be provided separately, or the antenna circuit may be provided as a part of the resonance circuit. The sensor unit includes a circuit for processing the detection result of the cut detection line. Furthermore, if necessary, a circuit for processing various sensors such as pressure, chemical substances, and light may be provided in the sensor unit. Further, an electrode for additionally inputting a value from the outside may be similarly incorporated in the sensor unit. The result of the cut detection line or the sensor can be communicated as a part of the identification signal in addition to the unique code unique to each main body 10a, 10a,. Therefore, it is preferable that the sensor unit is closely connected to the address decoder as a recording block. In addition to the unique code, the recording unit records contents recorded in advance or contents written from the outside by wire or wireless. The result (signal) output from the recording block to the signal processing block is obtained by, for example, a method of modulating the resonant load by a modulation circuit under the control of a digital control circuit, as in a normal wireless communication identification tag (IC tag). The response is output to the outside. Although not described in FIG. 5, congestion control, writing functions, and the like as used in existing wireless communication identification tags may be added.

  In the identification tag of the present embodiment, the unique codes unique to the main body portions 10a, 10a,... Included in the identification signal regularly correspond to the arrangement of the main body portions 10a, 10a,. In other words, in the present embodiment, the main body portions 10a, 10a,... Are arranged in a single line and are arranged in order on a straight line, so that, for example, the unique code of one main body portion 10a is assigned to the adjacent main body portion. What is necessary is just to set it as the result obtained by performing predetermined | prescribed calculation to the intrinsic | native code which 10a has. As the calculation at this time, for example, an arithmetic operation such as an arithmetic sequence or a geometric sequence can be cited. As an example, when m body parts 10a, 10a,... Are tape-like identification tags arranged in the longitudinal direction of a tape-like base material part, ..., (i-1), i, (i + 1), .. And a unique code included in the main body portions 10a, 10a,. This makes it possible to easily determine the possibility that the main body portions 10a, 10a,.

  When the identification signal is composed of multiple digits, the detection result of the presence or absence of cutting by the cutting detection line (cutting code when there is cutting) can be at any position (digit) in the identification signal. However, it is preferable that the unique code is in a higher digit in the identification signal than the detection result of the presence or absence of cutting. In this case, when the identification signals of the plurality of main body portions 10a, 10a,... Are read and the plurality of identification signals that have been responded are arranged, since the unique code is the upper digit, the read identification signals are the magnitudes of the upper digits. Therefore, the order of this arrangement is preferable regardless of the cutting position. These will be described in the examples described later.

  As a more specific example of the identification signal transmitted by each main body 10a, 10a, etc., as shown in FIG. 8, the sensor and the additional recording storage part were cut and destroyed from the upper digit to the lower digit. An example is shown in which a detection result C of no, a unique code I, and a result A of the first cut detection line 12a are placed, and further S is placed in the lower digit, such as the sensor result, additional contents, and other recorded contents. . In the present embodiment, the detection result of the second cut detection line 13a is also assigned to A. The respective areas C, I, A, and S in FIG. 8 may be continuous or may be placed with several digits between them. When several digits are placed between the areas C, I, A, and S in FIG. 8, a fixed value such as 0 or 1 is always transmitted to the empty digits. Is preferred. 8A shows that the main body portions 10a, 10a,... Are arranged in a higher dimension even when they are arranged in a low dimension such as one dimension or two dimensions as in this embodiment. In consideration of versatility, it is preferable to provide 3 digits or more, and more preferably 6 digits or more so as to correspond to a three-dimensional or higher-order arrangement. For unused digits, it is preferable to always transmit the same value as when disconnected.

  Communication between the identification tag and the receiver that receives the identification signal is performed in the same manner as in a normal wireless communication identification tag. At this time, since there are responses from a plurality of main body units, it is preferable to communicate by the method described in Patent Documents 2, 3, 4, and the like. As the subsequent processing, for example, the response content is processed by the following procedures [A] to [G].

  [A] Receives responses (identification signals) from all communicable main units.

  [B] For each response, the detection result C that is a result of destruction is judged as an unnecessary response and discarded.

  [C] The responses are rearranged in the order of the main body units.

  [D] It is confirmed whether there is a contradiction in the order of arrangement with the identification signal of the main body on the cut piece.

  [E] The responses of the main body units arranged in order are checked in order, the ones with the result A being “cut” are picked up, and the main body unit next to the main body unit with the result A being “cut” To the next main body section that is “cut” is on one cut piece.

  [F] The result of the first cutting detection line included in the detection result A and the second cutting whether the main body that has transmitted the identification signal whose result A is “cut” is at the end of the cutting piece A check is made based on whether there is a contradiction between the result of the detection line and the unique code I.

  [G] If a contradiction occurs in the confirmation procedure of the procedure [D] or the procedure [F], the procedure returns to the procedure [A] again.

  The above is one example of processing when there are responses from a plurality of main body units. In addition, although the case where it processed in order with procedure [A], [B], [C] was illustrated, the response is unnecessary from the result C in a certain response even in the middle of procedure [A]. If it is found, the process of discarding the response may be performed. In this case, the procedure [B] corresponds to being performed simultaneously in the procedure [A]. Similarly, the procedure [B] may be omitted, and during the procedure [C], when it is found from the result C of a response that the response is unnecessary, the response may be discarded. . In this case, the procedure [B] corresponds to being performed simultaneously in the procedure [C]. Further, for example, by setting the result C as the most significant digit of the response code, the procedure [C] may be combined into two groups of an unnecessary response and a necessary response. Judgment of the cutting position of the identification tag is not influenced by the selection of these exemplified methods or other methods, and the response processing method is determined in consideration of the storage capacity and processing time of the processing device after the response is read. You just have to decide what you want. In the procedure [G], when the number of times of returning to the procedure [A] is large, it is preferable to appropriately perform general exception processing such as issuing an alarm and interrupting the processing. Further, the procedure [D] and the procedure [F] are not necessarily required and can be omitted. Further, a code for confirming the reading value may be included in the identification signal in advance, and the reading may be repeated in the procedure [A]. The gist of the present invention is not affected by the reading value or the communication confirmation method.

<Example>
Hereinafter, examples of the present embodiment will be described. This embodiment is an example of the present invention, and the present invention is not limited to this embodiment.

  FIG. 9 shows the main body of the identification tag according to this embodiment. The main body 10 includes a semiconductor element 16 including a wireless identification communication processing circuit, an antenna 15, a first cut detection line 12, a second cut detection line 13, a write-once electrode 22, a sensor 21, The electrode 22 for additional recording or the break detection line 14 of the sensor 21 is provided. The semiconductor element 16 is electrically connected to other constituent members. Here, the connection is performed by wire bonding, but any connection method such as connection using a lead frame, TAB, chip size package, or the like may be used. The combination of the semiconductor element 16 and the antenna 15 is an identification signal transmission unit. In the present embodiment, the first cutting detection line 12 ′ of the adjacent main body part reaches up to the main body part (one main body part) 10 shown in FIG. It extends alongside the first cut detection line 12. Further, the second cutting detection line 13 ′ of the main body adjacent to the opposite side reaches below the main body 10. That is, when the main body portion 10 is viewed from the direction perpendicular to the direction connecting the adjacent semiconductor elements 16 on the mounting surface of the base material portion on which the main body portion 10 is mounted, the adjacent first cut detection line 12 ′ and The second cut detection line 13 ′ is arranged so as to overlap the semiconductor element 16. The direction connecting the adjacent semiconductor elements 16 can also be said to be the direction in which the line connecting the centers of the adjacent semiconductor elements extends.

  For example, the sensor 21 may be a sensor that senses pressure, light, temperature, chemical substances, and the like. What is necessary is just to select suitably by a use.

  Examples of the additional recording electrode 22 include an electrode for electrically writing a value, and an electrode for electrically writing a value by electrically connecting the electrodes with a conductive material.

  These sensors 21 and additional recording electrodes 22 are surrounded by the breakage detection line 14. Since the break detection line 14 is installed in the vicinity of the sensor 21 and the additional write electrode 22, when the identification tag is cut and the break detection line 14 is cut, the sensor 21, the additional write electrode 22 itself or the connection wiring is not connected. It breaks, and it becomes impossible to send a sensor output or additional recording signal to the semiconductor element 16. Accordingly, when the semiconductor element 16 determines that the break detection line 14 is broken, it is handled as no information from the sensor 21 or the additional recording electrode 22, that is, sensor information and additional recording information are not included in the identification signal. Can be.

  In the present embodiment, the first and second cut detection lines 12 and 13 are partly connected to the processing circuit, but may not be shared. In addition, the wiring of the sensor 21, the additional recording electrode 22, and the like are partially shared, but may not be shared. The arrangement of the constituent members of the main body 10 in FIG. 9 is an example. For example, the semiconductor element 16 may be arranged in the loop of the antenna 15.

  Next, a method for creating an identification tag according to the present embodiment will be described.

  As shown in FIG. 10 (a), an antenna 15, a break detection line 14, first and second cut detection lines 12, 13, and a write-once electrode are formed on a tape-shaped base portion 18 made of a polyimide flexible substrate. 22, a plurality of sensors 21 and their wiring patterns are provided.

  Then, the respective locations where the semiconductor element 16 is to be mounted on the base member 18, the intersection between the breakage detection line 14 and the first and second cut detection lines 12 and 13, and the intersection of the antenna 15 line In addition, an epoxy adhesive which is an insulator is applied.

  Next, the plurality of semiconductor elements 16 are respectively placed on an epoxy adhesive and fixed by adhesion.

  And between the wiring pattern and the semiconductor element 16, the intersection of the breakage detection line 14 and the first and second cut detection lines 12 and 13 and the intersection of the antenna 15 line are connected by a gold wire using a wire bonder. Do.

  Further, a transparent acrylic paint is applied to a portion other than the additional recording electrode 22 to form a protective layer. Note that the write-once electrode 22 remains exposed.

  In this way, as shown in FIG. 10, a plurality of main body portions 10, 10,... Are arranged in a one-dimensional manner on the tape-like base material portion 18. FIG.10 (b) is the figure which expanded the part of A of Fig.10 (a). The arranged semiconductor elements 16 are numbered sequentially from the left side, and a unique identification signal n is assigned to the nth semiconductor element 16.

  Here, the cut detection lines 12 and 13 and the break detection line 14 are connected in the semiconductor element 16 as shown in FIG. 11A, and the detection result of the cut is the cut detection line to the gate electrode of the field effect transistor. Depending on whether the power supply voltage is applied or not, the output value is obtained when the selection line becomes active. This output value constitutes one digit of the identification signal.

  The additional recording electrode 22 is connected in the semiconductor element 16 as shown in FIG. 11B, and the result of additional recording with the conductive material is that when the selection line becomes active for the same reason as the cutting detection line. It is obtained as an output value. This output value constitutes one digit of the identification signal.

  Further, when a pressure sensitive conductive rubber is connected as a pressure sensor, if the wiring is made in the semiconductor element 16 as shown in FIG. 11 (c), the identification signal is similar to the cut detection lines 12 and 13 and the additional recording electrode 22. The output result is obtained as one digit. Furthermore, by replacing the pressure-sensitive conductive rubber in FIG. 11C with a sensor such as an optical sensor or a chemical substance sensor, the sensor output can be obtained as one digit of the identification signal. Since the gist of the present invention is irrelevant to the type of the sensor 21 and the additional recording electrode 22, the output result of only the additional recording electrode 22 is used in the following description, and the sensor 21 is omitted.

  Each identification signal transmitted by each main body 10, 10,... In this embodiment is assigned the result (corresponding to C in FIG. 8) of whether or not the break detection line 14 is broken to the most significant digit. The unique code (corresponding to I in FIG. 8) unique to each main body 10, 10,..., And the result of whether or not the first cut detection line 12 is cut to the next 1 digit, The result of whether or not the second cut detection line 13 is cut off for the next 1 digit is 1 in the next 4 digits (the 6 digits below these unique identification signals correspond to A in FIG. ), The output results of four additional electrodes (corresponding to S in FIG. 8) are assigned to the next four digits, respectively, and a 128-digit binary number is set, with 0 being the least significant digit. Further, 1 is obtained as a result when the break detection line 14 and the first and second cut detection lines 12 and 13 are cut, and 0 is obtained as a result when the break detection line 14 is not cut. The number of digits and the value can be arbitrarily set regardless of the gist of the present invention.

  Next, as described above, the identification tag formed by arranging the 14 main body portions 10, 10,... Is cut into six pieces with a knife. As shown in FIG. 12, the cutting location is between the first and second main body portions 10 and 10, the fourth main body portion 10, between the seventh and eighth main body portions 10 and 10, and the twelfth main body portion. Between the tenth, thirteenth and fourteenth body portions 10 and 10. The unique code I represents the order of arrangement from 1 to 14 in decimal notation. In addition, in order to show that the main-body parts 10 and 10 of both ends are an edge part, a part of wiring is not created.

  When six pieces of identification tag slices are read by a plurality of wireless identification communication readers, the result shown in FIG. Note that there is no response from the main body with the unique code I = 12. In the cut detection result column in FIG. 13, C is the detection result of the break detection line, R is the detection result of the first detection line 12, and L is the detection result of the second cut detection line 13. Here, C is the first digit from the top of the identification signal, R is the 18th digit, and L is the 19th digit. Further, since the main body portions of I = 1, 14 at both ends are partially missing, the result is that the missing wires are cut.

  When the values of the identification signals are rearranged in order of magnitude, FIG. 13B is obtained. After the rearrangement, when the unique code I is arranged from the smaller one to the larger one and the main body part where R becomes 1 is on one slice, and R becomes 1, the next main body part is On another section. In order from the smaller to the larger unique code I, the arrangement of the main body on one slice is determined to be on the same slice in accordance with the value of R of the identification signal. Further, by confirming that L is 1 for the main body portion having the smallest unique code I on one section, the result of determining the arrangement of the main body portion on one section is checked. When R is examined in order from the smallest unique code to the largest unique code after the identification signals are rearranged, if C becomes 1, C is always the most significant digit, so C is always 1 after that. Therefore, the process ends.

  As described above, it can be determined which body portion is on the same identification tag section.

(Embodiment 2)
The identification tag of the second embodiment has main body portions 10b and 10b shown in FIG. Since the other components of the identification tag are the same as those of the first embodiment, only the main body portions 10b and 10b will be described below.

  In the present embodiment, the first cut detection lines 12b, 12b,... Exist, but the second cut detection lines do not exist. In the first embodiment, the cutting position is confirmed based on whether or not the second cutting detection line is cut. However, this confirmation is just a precaution, and the first cutting detection line itself is cut. Since the cutting position can be detected only by the detection result, even when the identification tag of the present embodiment is used, the cutting position can be determined when the identification tag is cut as in the first embodiment.

  Unlike the first embodiment, the first cut detection lines 12b, 12b,... Of the present embodiment are different from the connected identification signal transmitters 11b, 11b,. 11b,... (To the right side in the figure) and to the upper side in the figure of other adjacent identification signal transmitters 11b, 11b,. That is, when the adjacent main body portion 10b is viewed from a direction perpendicular to the direction connecting the adjacent identification signal transmission portions 11b, 11b,... On the mounting surface of the base material portion on which the main body portions 10b and 10b are mounted, The first cut detection line 12b is arranged so as to overlap the adjacent identification signal transmitter 11b. By being arranged in this way, when the adjacent identification signal transmitters 11b and 11b are cut and separated, the first cut detection line 12b is also cut reliably. Therefore, it is possible to reliably transmit the cutting detection result as a part of the identification signal. Other configurations and effects are the same as those of the first embodiment except for the second cut detection line. Since there is no second cut detection line, the identification signal is shortened accordingly, and the signal processing is simplified. Also, the manufacturing cost can be reduced.

(Embodiment 3)
The identification tag of Embodiment 3 has main body portions 10c, 10c,... Shown in FIG. 3, and the base material portion is not a tape shape but a sheet. The plurality of main body portions 10c, 10c,... Of the present embodiment are two-dimensionally arranged. That is, they are arranged not only in order in one direction but also in an array so as to spread over the entire plane.

  The main body portions 10c, 10c,... Of the present embodiment each have two first cut detection lines 12c, 12c,... And two second cut detection lines 13c, 13c,. In one main body 10c, the two first cut detection lines 12c and 12c extend from the identification signal transmitter 11c toward the other adjacent identification signal transmitters 11c and 11c, respectively. The two first cut detection lines 12c, 12c are arranged at an angle of 90 °. In addition, the identification signal transmission unit 11c of the one main body unit 10c includes the first cutting detection lines 12c and 12c extending from two adjacent identification signal transmission units 11c and 11c that are close to the extreme ends. The two second cut detection lines 13c and 13c of one main body portion 10c are arranged substantially in parallel with the two first cut detection lines 12c and 12c. These second cut detection lines 13c and 13c are at an angle of 90 ° to each other. The first and second cut detection lines 12c, 12c, 13c, and 13c extending from the one identification signal transmission unit 11c are divided into approximately four equal parts on the mounting surface of the base material centering on the one identification signal transmission unit 11c. It extends in the direction to do.

  The unique codes in the present embodiment are as follows. For example, if the main body portions 10c, 10c,... Are arranged in m rows and k columns, the identification signal transmitters 11c, 11c,... In the first row are represented by: (i-1), i, (i + 1), .., And the identification signal transmitters 11c, 11c,... In the second row are ..., (i + k-1), (i + k), (i + k + 1),. Thus, the first line has a unique code that increases by one in addition to k. It should be noted that the difference of the unique code from the adjacent row may be k + 1 or more so that the continuity can be easily determined.

  In the present embodiment, the base material portion is a sheet and each of the main body portions 10c, 10c,... Is two-dimensionally arranged. However, the manufacturing method is the same as in the first embodiment, and the cutting position is determined by receiving an identification signal. The determination method needs to perform calculations in two directions, ie, the row direction and the column direction, but is basically the same as in the first embodiment. In the present embodiment, there are four other main body portions 10c, 10c,... That are closest to one main body portion 10c except for the end portion of the identification tag, and whether or not the first main body portion 10c, 10c,. It can detect by the 2nd cutting | disconnection detection lines 12c, 12c, 13c, and 13c. Other effects are the same as those of the first embodiment.

(Embodiment 4)
The identification tag of the fourth embodiment has main body portions 10d, 10d,... Shown in FIG. 4, and the base material portion is not a tape shape but a sheet as in the third embodiment. Although the identification tag according to the fourth embodiment has a part that is partially different from the identification tag according to the third embodiment, many of the parts are the same.

  In the identification tag of the present embodiment, each of the main body portions 10d, 10d,... Has two first cut detection lines 12d, 12d, but the second cut detection lines are not included. 3 is different from the identification tag. This is exactly the same as the relationship between the first embodiment and the second embodiment. Also in the present embodiment, as in the second embodiment, the first cut detection lines 12d and 12d extend toward the adjacent identification signal transmission unit, and the tip of both the identification signals along the mounting surface. When viewed from the direction perpendicular to the line connecting the transmitters, it extends to a position where it can be seen overlapping with the adjacent identification signal transmitter.

  In this embodiment, there are four main body portions 10d, 10d,... That are closest to one main body portion 10d, but the first cutting detection lines 12d, 12d of the main body portion 10d extend to two of them. The first cut detection lines 12d and 12d extend from the remaining two main body portions 10d and 10d toward one main body portion.

  In the present embodiment, since there is no second cut detection line, the cut position cannot be rechecked. However, the identification signal is simplified correspondingly, the processing after reception is simple, and the identification tag is manufactured. Can be done at low cost. The other effects are the same as those of the third embodiment.

(Embodiment 5)
The identification tag according to the fifth embodiment has a main body 10e shown in FIG. 6, and there are some parts that are different from the identification tag according to the second embodiment, but many parts are the same, so the different parts will be described below. To do.

  In the main body 10e of the present embodiment, the tip of the first cut detection line 12e extending to the adjacent main body overlaps the adjacent identification signal transmitter 11e. That is, the tip of the first cut detection line 12e is placed on the adjacent identification signal transmitter 11e. By arranging in this way, when the adjacent identification signal transmitters 11e and 11e are cut and cut off, the first cut detection line 12e is also cut off reliably. Therefore, it is possible to reliably transmit the cutting detection result as a part of the identification signal. Other configurations and effects are the same as those of the second embodiment except for the second cut detection line. Note that the tip of the first cut detection line 12e may be disposed below the identification signal transmitter 11e.

(Embodiment 6)
The identification tag according to the sixth embodiment has main body portions 10f, 10f,... Shown in FIG. 7, and there are parts that are partially different from the identification tag of the fourth embodiment, but many parts are the same, and therefore different parts. Is described below.

  In the main body portions 10f, 10f,... Of the present embodiment, the tips of the first cut detection lines 12f, 12f,... Extending to the adjacent main body portions overlap the adjacent identification signal transmission portions 11f, 11f,. It has been. That is, the first cut detection lines 12f, 12f,... Are placed on the adjacent identification signal transmitters 11f, 11f,. With such an arrangement, when the adjacent identification signal transmitters 11f and 11f are cut and separated, the first cut detection line 12f is also cut reliably. Therefore, it is possible to reliably transmit the cutting detection result as a part of the identification signal. Other configurations and effects are the same as those of the fourth embodiment except for the second cut detection line. Note that the tip of the first cut detection line 12f may be disposed below the identification signal transmitter 11f.

(Other embodiments)
The above embodiments are examples of the present invention, and the present invention is not limited to these examples. For example, the minimum number of first cut detection lines is only the same as the dimension of arrangement of the main body. When the main body portions are arranged n-dimensionally, at least n cutting detection lines arranged close to the adjacent main body portions are provided for each main body portion. However, since there is an unnecessary main body at the end, it is not necessary to reduce or provide a cutting detection line arranged close to the adjacent main body in such a main body. Further, the number of second cut detection lines may be increased to a minimum necessary number or more for checking the identification signal.

  The main body part may or may not be provided with a break detection line. The rupture detection line may also serve as the antenna or may be provided separately. For example, when functions other than identification signal communication unique to the main body, such as sensors and additional recording electrodes, are connected to the main body, are the functional portions other than identification signal communication unique to the main body disconnected? Therefore, it is preferable to provide a break detection line. When only the communication of the identification signal unique to the main body is used, it may be replaced with the function of the break detection line by determining whether the communication can be normally performed.

  The first and second cut detection lines and break detection lines may be connected to the circuit of the main body at one place when cutting is determined by capacitance or inductance, as in the above embodiment. More preferably, both ends of the cutting detection line are connected to the circuit of the main body as a loop line, and the cutting is determined as an electric resistance.

  The identification tag may be linear (one-dimensional) such as a strip or string, or planar (two-dimensional) such as a film or plate. As a linear example, a plurality of main body portions are arranged in the length direction of the adhesive tape, and the tape is appropriately cut and used at a desired length. In this case, an identification tag can be attached at the same time as sealing the package. In addition, as a planar example, two or more two-dimensionally arranged main body parts on a wrapping sheet, cut according to the packaging object, used as a label of appropriate size, or a main body part connected to a sensor And using them in an array.

  When a break detection line is provided in the main body, according to the detection result of the break detection line, the identification signal is not transmitted when the break is detected, and the identification signal is transmitted only when the break is not detected. It is also possible to control. As another method, the identification signal may be transmitted regardless of the detection result of the break, and the detection result of the break detection line may be included in the identification signal and transmitted. When transmitting the identification signal including the detection result of the break detection line, the detection result is included in which position of the identification signal (corresponding to which digit in the numerical value when the sign is handled as a numerical value). However, it is preferable to use the most significant digit. In many processing apparatuses that handle numerical values, those that can determine the sign of a numerical value by the most significant digit are generally used, and there are cases where a positive or negative result can be easily processed without performing a comparison operation. Also, even if it is not easy to judge positively and negatively, if the identification signals of a plurality of main body parts that responded to reading are arranged in order of magnitude, the identification signal with the same most significant digit is continuous, so that the self is broken This is preferable because the identification signals are divided into two groups, one that is not broken, and the body portion that is not broken can be easily selected.

  For the communication and signal processing circuit, antenna, wiring, first and second cut detection lines, base material, sealing material, and the like included in the main body, the same materials and manufacturing methods as those for normal wireless communication identification tags are used. be able to. For the semiconductor, a material manufacturing method such as an organic semiconductor system such as a low molecular weight organic molecule, an oligomer or a polymer, or an inorganic system such as silicon may be selected. In addition to metals, organic conductors such as conductive polymers and their composites can be used for antennas and circuit wiring, and manufacturing methods are also wired using fine wires or formed by plating. Or by printing, baking after printing, electropolymerization, or a combination of other methods and various methods. These selections may be determined based on conditions such as use environment, use time, and cost, and the gist of the present invention is not affected by these manufacturing methods.

  INDUSTRIAL APPLICABILITY The present invention can be used for various identification tags, and generally can be used for individual identification tags, for example, POS and packing tags used for package management, product management, and FA management, packing materials and sealing materials having these functions, etc. It can also be used. It can also be used to manage goods at home. It can also be used as an identification tag attached to animals and plants. It can also be used for individual identification and table of contents such as books, forms and files in book shelves and filing systems. It can also be used for admission tickets.
