2. Description of the Related Art In the conventional method for producing a wireless tag, a costly method is generally used in order to provide durability since the wireless tag is not cheap. As a method of making a card-shaped tag, the antenna is molded on the PET sheet with metal ink or aluminum vapor deposition, a wireless tag chip is mounted, and it is put in the card-shaped tag. Make a card-shaped tag. The method of making a stick or coin-shaped tag is to connect a metal antenna to the chip for the wireless tag,
Put it in a plastic rod-shaped or coin-shaped object to make a rod-shaped or coin-shaped tag.

The cost of attaching the wireless tag to an object is not low. To attach the created wireless tag to an object,
Adhesive tape or adhesive material is attached to the wireless tag, and it is attached to an object or embedded in an object. The cost increases only by attaching the adhesive tape to the RFID tag.

Many conventional wireless tags have a congestion control function. The congestion control function is a function of controlling, when a plurality of wireless tags are within the reading range of the reader / writer at the same time, the wireless tags not to simultaneously respond but to individually respond. By controlling to respond individually, the reader / writer can read the data of each wireless tag. In order to realize the congestion control function, it is necessary to execute a protocol that determines the communication order between the reader / writer and the wireless tag, so the mechanism of both the wireless tag and the reader / writer (reader) becomes complicated, and the cost increases. Invite.

The wireless tag without the congestion control function is low in cost, but when a plurality of wireless tags are included in the reading range of the reader / writer, a response may be returned at the same time. It becomes impossible to read the individual data of.

[0006]

In order to attach the wireless tag to an object, a card-shaped, rod-shaped or coin-shaped tag is used.
Since it is necessary to apply an adhesive tape or an adhesive material, it is costly to install. For applications that use a lot of wireless tags,
The increase in the cost of mounting the wireless tag is an obstacle to using the wireless tag.

[0007] The increase in the cost of the wireless tag is an obstacle to using the wireless tag. Therefore, it is desirable to use an inexpensive wireless tag having no congestion control function. Therefore, when a situation occurs in which a plurality of wireless tags having no congestion control function enter the reading range of the reader / writer, it is necessary to be able to confirm the data of the plurality of wireless tags. For example, if a wireless tag that does not have a congestion control function can be used in order to check whether a plurality of items are contained in a box, an inexpensive wireless tag can be used, which is advantageous in terms of cost.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a wireless tag, a wireless tag bundle, a wireless tag member, a wireless tag mounting device, a reader, and an identification method which are excellent in cost. And

Each wireless tag is fixed to the tube 1808 with an adhesive material or the like. The wireless tag tube 1808 having a plurality of wireless tags can be used to mount a plurality of wireless tags at regular intervals. For example, if it is installed on the side of a road and used with an electronic cane, it can be provided to people with disabilities.

FIG. 18 shows an RFID tag attaching device for attaching the RFID tag bundle of FIG. 14 or 15 (not excluding the RFID tags alone) to a sheet or paper. The upper portion 1902 and the lower portion 1918 of the wireless tag mounting device are connected to the connecting portion 1
They are connected at 920, and the upper portion 1902 and the lower portion 1918 move around the connecting portion 1920. Top 1902
Place a sheet or paper between the lower part and the lower part 1918,
When the 902 is pressed against the lower portion 1918, the wireless tag 190
The four feet (antenna) stick into the sheet. When the wireless tag is pressed further, the legs of the wireless tag are bent as shown in FIGS. 4, 6, 8 and 9, and the wireless tag is attached to the seat. The storage unit 1906 is for storing a bundle of RFID tags 1904 (a bundle of RFID tags), and the plate 1908 is for pushing a bundle of RFID tags 1904 forward by a spring 1910. When a sheet is sandwiched between the upper portion 1902 and the lower portion 1918 and the upper portion 1902 is pressed against the lower portion 1912, one of the wireless tags is pushed forward by the pushing portion 1916 and stuck to the sheet. When the upper portion 1902 is further pressed, the legs of the wireless tag are bent inward or outward by the bending guide portion 1912, and the wireless tag is connected to the sheet.

The present embodiment is similar to a stapler for fixing paper or the like with a metal wire. However, the thing to be attached is not a metal wire but a wireless tag having an IC to be protected, and there is an embodiment in which the bending guide portion 1912 bends the foot inwardly except for bending inward.
Further, when the wireless tag is inserted into the sheet, it is necessary to read or write data from the wireless tag. The reader / writer unit 1914 is attached to the head of the wireless tag mounting device and reads / writes data of the wireless tag after or before mounting the wireless tag on the sheet. The data to be written and the data to be read are stored in the control device 1922 of the reader / writer unit 1914. Also,
If necessary, it has a transmitter for sending the read data to another device.

FIG. 2 shows the mechanism for bending the legs of the wireless tag.
Use 5 to explain. The wireless tag 2602 is pushed down by the pushing portions 2614 and 2616. Feet 2606 with bent antennas 2604 and 2608 of the wireless tag
2610 pierces a sheet 2612 of a product or the like, further penetrates the sheet 2612, and reaches the bending guide portions 2618 and 2620. When the upper portion 2622 is further pressed against the lower portion 2624, the push-out portions 2614 and 2616 are attached to the wireless tag 2.
Press 602 further down, and foot 2606 and 2610
Is bent outward according to the guides of the bending guide portions 2618 and 2620 and fixed to the seat 2612 as shown in FIG. The push-out portions 2614 and 2616 are spaced apart so as to protect a portion of the wireless tag 2602 in which the IC chip is incorporated, and are pressed against the horizontal portions (horizontal portions) of the antennas 2604 and 2608. As a result, the wireless tag 2
602 is pushed out from the storage unit 1906 in FIG.

The wireless tag of the present invention can be attached to various types of products (or product incidental products).
Also, the product is classified into various types. FIG. 19 shows an example of the data of the wireless tag for satisfying such requirements. The service identifier 2004 indicates a specific product or service. Service data 2006
Is a data area used to indicate the type of a specific product or service. These are pieces of information for identifying products or services, and are stored in the storage unit of the wireless tag as N-bit inspection information 2002 represented by a binary number.

The wireless tag of the present invention is premised on having no congestion control. The wireless tag that does not have the congestion control is inexpensive because the congestion control circuit is not required in the IC chip of the wireless tag. Here, there arises a problem that data of a plurality of wireless tags cannot be individually taken out.
However, if the electric characteristics of the microwave used in the communication of the wireless tag are used, even in a wireless tag without a congestion control mechanism, even when the reader / writer (reader) reads multiple wireless tags, The types can be distinguished and the number of wireless tags can be confirmed within a limited range. In the present invention, some functions that replace the congestion control function are realized by devising the setting of the data of the wireless tag.

When a microwave is sent to the reader / writer to read the data of the wireless tag, the wireless tag sends the data in the wireless tag back to the reader / writer by the microwave. At that time, when a plurality of wireless tags without congestion control receive microwaves from the reader / writer, the plurality of wireless tags start returning data by microwaves. Since the reader / writer reads the microwaves of a plurality of RFID tags at the same time, it becomes impossible to identify the data of each RFID tag. Actually, the read data is obtained by taking the logical sum (in the case of positive logic in which "1" is High) of the microwave data sent from the plurality of wireless tags. For example, when the wireless tag 1 transmits data “0101” and the wireless tag 2 transmits data “1010”, the reader / writer reads the data “1111”. The reader / writer side sends microwaves to the wireless tag at regular intervals as shown in FIG. 2502 and 2504, 2506, 2508
Is a time zone in which no microwave is transmitted to the wireless tag, and 2510, 2512, and 2514 are time zones in which a microwave is transmitted from the reader / writer to the wireless tag. The actual waveform is the time zone in which the microwave is emitted in the section of 2510, and is actually the waveform of the microwave. The wireless tag returns data to the reader / writer when receiving microwaves. The wireless tag returns data to the reader / writer in synchronization with the rising edges of 2510, 2512, and 2514.

There is a demand for confirming that a predetermined number of products such as products are attached with a wireless tag and that a predetermined number is included. This is a request to confirm that the same product contains right and left foot parts without opening the box when a plurality of items, such as shoes, are contained in the box. Also, there is a desire to make sure that you put two identical items in the box. In the present embodiment, the same product for right foot or left foot will be described as an example. Since the shoes are the same, the service identifier is the same data as follows. The data is expressed in binary bits. Service identifier: “0011” However, in order to distinguish between the right foot and the left foot, the following different product identifiers are used in the service data. Product identifier for shoes for right foot: “10” Product identifier for shoes for left foot: “01” There are three cases when the RFID tag is read from the outside of the box by the reader / writer. When the shoes for the right foot and the shoes for the left foot are in the box, the data "001111" can be read. The first 4-bit data is the service identifier. Even if there are two wireless tags,
Since the service identifiers of the shoes for the right foot and the shoes for the left foot are the same, the service identifier “0011” of the shoes is read. "1" of the 5th and 6th bits is obtained by reading the product identifier of the service data of the tags attached to the shoes for the right foot and the shoes for the left foot, respectively. Each bit is logically ORed and becomes "1".

When the radio tag in the box containing only the shoes for the right foot is read, the data "001110" is read.
Also, if the two shoes for the right foot are included, the same "00
The data is 1110 ". On the other hand, if you read the RFID tag on the box containing one or two shoes for the left foot,
The data "001101" is read. If the right foot and the left foot are included, "001111" should be read, so "001110" or "001101"
In case of such data, it can be understood that the contents in the box are incorrect. By thus confirming the service identifier and the product identifier in the service data, it is possible to inspect the product insertion error without opening the box.

According to the present invention, not only two types as in the present embodiment but also the number of bits to which the product type is assigned can be increased to deal with a product having two or more types. For example, if it is necessary to confirm that there are three product types, three bits may be used. Further, when a plurality of products of the same type are stored, it is possible to confirm the existence of a plurality of the same products by virtually dividing the product types. In this way, by assigning "1" to different data positions as the product identifier for identifying the product type, it becomes possible to know which product type is stored. In this embodiment, "1" is assigned to each type. If it is negative logic,
Assign “0”.

As a matter of course, if the plurality of wireless tags do not return data at the same time due to the influence of the positions where the plurality of wireless tags are placed, the congestion control function is not necessary. The contents can be judged using the data read without problems.

In this method, two shoes for the right foot are used,
Even if one shoe for the left foot is included, the read data is "001111", and it cannot be distinguished from the case where one shoe for the right foot and one shoe for the left foot are included. However, in the case of a shoe, there is no space for two shoes for the right foot and one shoe for the left foot in the box, and the appearance can be easily seen from the outside of the box.

FIG. 20 shows an embodiment of a reader / writer (reader) for reading the data of the wireless tag and evaluating the consistency of the data of the wireless tag. The reader / writer 2102 has an antenna 2104 for reading data of a wireless tag,
Microwaves are transmitted from 104 and the response from the wireless tag is read. The result is displayed on the display 2106.
The switch 2108 is a power switch, and each time the switch is pressed, the power is turned on or off. The switch 2110 is an operation switch that confirms the matching of the wireless tags. When the operation switch 2110 is pressed, microwaves are transmitted from the antenna 2104 to the wireless tag, data of the wireless tag is read, and consistency is checked. It is determined whether the read data matches the data in the reader / writer, and if they match, the display 2106 indicates that they match.
If there is no match, it is displayed at 2106 that there is no match. When the operation switch 2110 is pressed again, the reading of data from the wireless tag is stopped.

When a wireless tag is attached to a product and the product is contained in a box or the like, if the product identifier of the tag that should be attached to the product is the same as the read product identifier, the consistency can be confirmed. , You can check the products in the box without opening the box. This processing will be described with reference to FIG. If the operation switch 2110 of the reader / writer 2102 is pressed, the processing is started (2202). If the operation switch 2110 is not pressed again (2204), the data consistency check of the wireless tag is repeated (220).
6). It is checked whether the read data is consistent with the data in the reader / writer (2208), and if not, the display 2
It is displayed on 106 (2212). Then, it is confirmed whether or not the operation switch 2110 is pressed, and if not pressed, the consistency is checked again. If it is pressed, the operation ends (2216). On the other hand, if they match, the display 2106 indicates that they match (22
14) and the operation ends (2218).

For example, in the previous shoe example, the service identifier is the service identifier: "0011", and the product identifiers of the shoes for the right and left feet are the product identifiers of the shoes for the right foot: "10" and the shoes for the left foot. The product identifier of: was "01". If you can read the RFID tag inside the box containing both right and left foot shoes and read "001111", you can confirm that you have both right and left foot shoes. The fifth and sixth bits are the bit position of the product identifier in the right foot shoe and the left foot shoe, respectively. If both are "1", it indicates that both right and left foot shoes are included. If the RFID tags are far apart and the RFID tags for shoes for the right foot and the RFID tags for the left foot are read separately, if the data of "001110" and "001101" can be read from the RFID tag of one box , You can see that the box contains both right and left foot shoes. If you can only read either "001110" or "001101" data from one box,
You can see that it only contains shoes for the right or left foot. In the consistency check 2210 of FIG. 21, if both the product identifiers of the shoes for the right foot and the shoes for the left foot can be read, it is considered that they match. Therefore, when the RFID tags of the shoes for the right foot and the shoes for the left foot are read separately, the read data is once stored, the read data is logically ORed again, and if the product identifier becomes "11", Considered consistent. When the RFID tags of the shoes for the right foot and the shoes for the left foot are read at the same time, the product identifier is "11", and it can be seen that they are matched in one reading.

It is possible to assign a plurality of bits as the product identifier instead of one bit. For example, if you have a jacket and pants in a box like pajamas,
To inspect without opening the box, add “01”, “10”, and S, M, and L, which are the sizes of the jacket and pants, respectively.
Allocate “11”. If the size of the jacket is represented by the upper 2 bits of the service data and the size of the pants is represented by the following 2 bits, "0101" is selected for the S size combination and "1" is selected for the M size combination.
If it can be read as "010", it is possible to confirm that the size is appropriate even if a wireless tag without a congestion control function is used. As in the present embodiment, a plurality of bits may be set depending on the type of product. You may need a way to assign.

When there is not only one "1" bit in the product identifier as in the pajamas example, in order to confirm that the product type is surely included, in addition to the product identifier,
It is necessary to add the number of "0" s and the number of "1" s of the product type data to the product identifier. In the example of pajamas, if you have L size pants and L size pants and S size and M size jackets, and you check only the product identifier,
It becomes "1111", and it looks like an L-sized jacket and pants are included. In this way, when the product identifier is assigned using a plurality of bits, the product type confirmation data (confirmator) that uses the binary number indicating the number of bits of "0" and "1" of the product identifier is used. In this embodiment, in addition to 2 bits for indicating the size, 2 bits are used for indicating the number of "0" and "1" bits. The item identifiers of the jackets of each size and the data of the identifier for confirming the item identifiers are as follows. S size: “010101” M size: “100101” L size: “110010” Here, the first 2 bits indicate the size, and the next 2 bits indicate the first 2 bits “0” represented by a binary number. The last two bits indicate the number of "1" of the first two bits represented by a binary number. If you set the checker like this, S
When there are two jackets of size M and M, the data read from the RFID tag is "110101", and the number of "0" or "1" indicated by the identifier and "0" or "1" of the product identifier. It can be seen that items other than L-sized jackets are included because the numbers of "are inconsistent. It should be noted that whether to use only the number of bits of "0" or "1" as a confirming element or to use both of them as in the present embodiment depends on the data to be confirmed.

When there are a plurality of shoes and there are a plurality of different service identifiers for each, the method of the previous embodiment mixes the right shoes and the left shoes of different products in the box. If it is inside, it may not be detected. It is assumed that the service identifiers of the products of shoes A and shoes B are as follows. Service identifier for shoe A: "0011" Service identifier for shoe B: "0010" The type of shoe for the right and left shoes of each shoe is the same as before, and the product identifier in the service data is as follows. . Product identifier of shoes for right foot: "10" Product identifier of shoes for left foot: "01" When such a product is present, when shoes for left foot of B shoe are mixed with products for A shoe, In the above embodiment, it may not be possible to identify that a product having another service identifier is mixed. When the service identifier and the product identifier are read, the result is "001111", which is the same as the data containing the shoes for the right and left shoes of the shoe A.

Even if there is such a possibility, in order to detect that the shoe for the left foot of the shoe B is squeezed in the product for the shoe A, the number of bits of "0" of the service identifier is set. A checker expressed in binary is added after the service identifier,
By checking the consistency of service identifiers, it is possible to detect that different products are mixed. A shoes and B in the previous example
The shoe service identifier and the number of bits that are "0" as a service identifier confirmer, which is data for confirming the service identifier, are as follows. Number of bits of service identifier of shoe A + “0” (service identifier identifier): “0011” + “010” = “001”
1010 "B shoe service identifier + number of bits of" 0 "(service identifier identifier):" 0010 "+" 011 "=" 001 "
[0011] The 3 bits following the service identifier are the identifiers that represent the number of bits that are "0" of the service identifier in binary numbers (all are represented in binary numbers). The service identifier of shoe A is "0011". Therefore, the number of bits of “0”, which is the service identifier checker, is “010”. By doing so, the number of bits for the right foot of A shoe and the left foot of B shoe are When shoes are mixed, the result is “001101111”, and by checking the consistency between the number of “0” s in the service identifier and the number of “0s” represented by the service identifier checker,
You can see that different products are mixed. The first 4-bit "0011" is a logical sum of the service identifier of shoe A and the service identifier of shoe B. If only this is seen, it can be regarded as the service identifier of shoe A. The subsequent 3 bits "011" represents the number of bits of "0" of the service identifier by a binary number. However, this number is the first four
It conflicts with the number of 4-bit "0" s indicating the bit service identifier. Therefore, it can be understood from the read data that shoes with different service identifiers may be included. 2 bits "11" following the service identifier identifier
Indicates that the shoes for the right and left feet are included. However, the data of the service identifier identifier, which indicates the validity of the service identifier, indicates that shoes of different products are likely to be in the box.

In the above embodiment, a checker that represents the number of "0" bits by a binary number is used to check whether the service identifiers of other products are mixed. However, a parity check or error detection code is used. Can also be achieved by using. The parity check adds the number of "1" bits of the service identifier and the bits for parity check,
This is a method of determining the value of the parity check bit so that it becomes even or odd. The error detection code is a method using an algorithm such as a CRC (Cyclic Redundancy Check) method.

FIG. 23 shows an embodiment for checking the consistency of service identifiers when there is a possibility that there are multiple service identifiers because there are multiple types of products such as shoes.

If 10 is pressed, the process is started (2402).
If the operation switch is not pressed again (240
4) The RFID tag is read (2406). It is evaluated whether the read service identifier and the service identifier identifier are inconsistent (2408), and if they are inconsistent, the product is not valid (2412). If there is no inconsistency, the contents of the product are appropriate. Is shown (2410). For example, in the previous examples of shoes A and B, when the service identifier and the identifier indicating the number of "0" of the service identifier in binary numbers were added, the data was as follows. Service identifier of shoe A + identifier indicating the number of bits of "0" in binary number: "0011" + "010" = "00110"
10 "B shoe service identifier + identifier indicating the number of bits of" 0 "in binary number:" 0010 "+" 011 "=" 00100 "
11 ”If the read data is“ 0011010 ”, it is known that the RFID tag is attached to the A shoe, and if the read data is“ 0010011 ”, the RFID tag is attached to the B shoe. Any other data indicates that the content of the product is not normal.

In the embodiment using shoes as an example, it was possible to confirm whether or not the wrong item was contained, but it was not possible to detect that the correct item was contained in the plural items. In order to confirm that one correct item is included, continuous data indicating individual items and number identifiers that confirm their validity are used in addition to the item identifier.

The data structure using the individual product number and the number confirmer is composed of three fields of a service identifier, an individual product number and a number confirmer. The individual product number is a serial number or a random number for identifying each individual product, and uses a predetermined number of bits represented by a binary number. The number confirmer is data for confirming the validity of the individual product number, and represents the number of bits of "0" or "1" of the individual product number by a binary number. In the example shoe example, the service identifier of the shoe + the identifier of the service identifier + the product identifier of the right foot + the individual item number + confirmator + the product identifier of the left foot + the individual item number + confirmator. In the case of shoes for the right foot, the product identifier and the individual product number of the left foot, and the confirmation element are "0". An example of shoes for the right foot is as follows. "0011 010 1 001011110 01
01 0 0000000000 0000 ”Spaces are separated for clarity. The first“ 0011 ”is the service identifier indicating the product A shoes, and the subsequent“ 010 ”is the service indicating the number of“ 0 ”in the service identifier. Identifier identifier, followed by "1" is a product identifier indicating that the shoe is a right foot, followed by "0010"
11110 ”is the individual number of the right shoe, followed by“ 0 ”
Reference numeral 101 ”is an individual item number identifier indicating the number of bits of“ 0 ”of the individual item number. Since the three fields after that are fields for the left foot, all are“ 0 ”. The data of the RFID tag on the left shoe is, for example, as follows: "0011 010 0 0000000000 00"
00 1 0001001110 0110 "The first and second fields are the same as the data of the RFID tag of the shoe for the right foot. The third, fourth and fifth fields are
Since it is data for the right foot, it is all "0". The sixth field is a product identifier indicating the left foot,
After that, "0001001110" is the individual item number of the left foot shoe. After that, "0110" is an individual item number checker indicating the number of "0" s in the individual item number.

If one shoe for the right foot and one shoe for the left foot are correctly contained in the box, the following data can be read when the data of the two RFID tags are read at the same time. If possible, you can check that it is entered correctly. "0011 010 1 001011110 01
01 1 0001001110 0110 "The first" 0011 "of this data is a service identifier indicating the product A shoes, the subsequent" 010 "is a service identifier confirmer indicating the number of" 0 "s of the service identifier, and thereafter. "1" is a product identifier indicating that it is a right foot shoe, "0010111010" following it is the product number of the right foot shoe, and "0101" after that is the number of bits of "0" of the product number. "1" after that is a product identifier indicating the left foot, "0001001110" after that is the individual product number of the shoe on the left foot, and "0110" after that is "0110". , Is an individual product number identifier indicating the number of individual product numbers “0.” Since the service identifiers for the right and left feet and the individual product numbers and their respective identifiers are consistent, You can check that each shoe is included.

In order to confirm whether or not at least one shoe for the right foot is contained in the box, the individual item number and the individual item number checker should be matched. For example, if the following two shoes for the right foot are contained, "0011 010 1 00101110 10 01
01 0 0000000000 0000 "" 0011 010 1 0010110010 01
10 0 0000000000 0000 ”When the data of such two RFID tags are read at the same time, the individual product number is“ 0010111010 ”and the individual product number identifier is“ 0111 ”. This is because the logical sum of the data of the five fields is obtained.By checking the individual product number confirmer, the number of bits of "0" in the individual product number and the binary number "0" represented by the individual product number confirmer. It can be seen that there is more than one shoe for the right foot due to the different numbers.

As described above, it is possible to detect whether or not a plurality of products are contained by attaching the individual product number and the confirmation indicator representing the number of bits of "0". This is because the logical sum of the data is taken and the number of bits of "0" disappears if there is "1" at the same position, but the checker uses the number of "0" for confirmation. Therefore, if the value of “0” is logically ORed with “1” and disappears, the number represented by the checker increases without decreasing. An example of confirming the consistency of the RFID tag with such a confirmation element will be described with reference to FIG.

In order to manage the type and confirm whether or not a plurality of objects are contained by using a wireless tag having no congestion control function, it may be necessary to determine the mounting order of the wireless tags. If you are serially producing only the same product type,
A product identifier corresponding to the product may be attached. However, when attaching a wireless tag after the product is completed, the order of attachment may be a problem. An embodiment for solving this is to arrange the RFID tags in a certain order to form the bundle when the bundle of the RFID tags of the RFID tag mounting device of FIG. 18 is formed. When the RFID tags are bundled as shown in FIG. 14 or FIG. 15, in the example of shoes, when the RFID tags are attached to the attachment machine by alternately attaching the RFID tags for the right foot and the left foot,
Make it easy to wear.

In addition, it goes without saying that the present invention can be variously modified and implemented within the scope of the present invention.

According to the present invention, since the RFID tag is mounted by using the antenna of the RFID tag, the mounting cost can be reduced. Even if you use an inexpensive wireless tag that does not have congestion control, by preparing a data field that is "1" corresponding to the type of product as data, you can confirm that the product is complete.
