Description

  The present invention relates to a rewritable sheet management system, a rewritable sheet management method, and a management program for issuing a rewritable sheet accompanied by a wireless information medium capable of wirelessly reading and writing information. The present invention relates to a rewritable sheet management system for making a determination, a rewritable sheet management method, and a management program.

  RFID (Radio Frequency IDentification) tags, which are a type of wireless information medium that can read and write information wirelessly, have been reduced in price, but at the present time (as of 2006), it is about several tens of yen to 100 yen. Even if it is cheaper, it is said that it costs around several yen. Therefore, the cost of managing products etc. using a set number of RFID tags is still high. Considering that barcodes, which are typical alternatives, only require printing, replacement of barcodes with RFID tags is difficult to proceed even considering the communication distance and data storage capacity that are the merits of RFID tags.

  Therefore, as a method of reducing the operation cost when using the RFID tag, a method of using the RFID tag a plurality of times by rewriting internal data is considered. For example, when an RFID tag is attached to a product price tag in the apparel industry, when a product is delivered, a store clerk removes and collects the price tag attached to the RFID tag and reuses it to reduce costs. For example, if the cost of the price tag attached to the RFID tag is 300 yen, the cost per use is 0.3 yen if used 1000 times.

  In such an RFID tag, the data in the RFID tag cannot be read unless a dedicated device (RFID reader) is used. Therefore, a separate print for displaying information such as product name and price to the customer is required. Become. Even in consideration of the case where the RFID tag is broken, printing is also necessary as an alternative means for holding information, such as printing a barcode storing equivalent information.

  Therefore, for example, it is conceivable to use a rewritable sheet. A rewritable sheet is a sheet that can be rewritten a plurality of times (several hundred to several thousand times) by repeating printing and erasing with a dedicated printer. FIG. 5 shows an example of a rewritable sheet with an RFID tag attached thereto. Hereinafter, the rewritable sheet with the RFID tag attached is referred to as an RFID-attached rewritable sheet. The RFID-attached rewritable sheet shown in FIG. 5 has an RFID tag 902 attached to the surface of the rewritable sheet 901.

  Since the rewritable sheet and the RFID tag have usage restrictions such as the number of times they can be rewritten, it is necessary to determine whether or not the rewritable sheet or RFID tag can be rewritten when using the rewritable sheet with RFID. For example, it is necessary to determine whether the number of times of use does not exceed the number of rewritable times. In many conventional usage methods, the current number of times of use is stored in the RFID tag, and the number of times of use is read from the RFID tag at the time of rewriting, and it is determined whether or not the number of rewritable times has been exceeded.

  Japanese Patent Application Laid-Open No. 2004-26883 discloses a printer control system that can automatically specify the use stop time of a leuco light card according to information related to the limit number of times stored in a memory corresponding to the read ID information. Is described.

JP 2005-138572 A (paragraphs 0034-0041)

  First, when determining whether or not rewriting is possible by storing data such as the number of times of use in the RFID tag, when the RFID-attached rewritable sheet and the RFID tag that does not use the rewritable sheet are mixed, it becomes a reading target from the RFID tag. There is a problem in that the data structure is different and the reading process is complicated. In addition, when the data stored in the RFID tag is increased, there is a problem that the reading speed is also reduced. Therefore, it is desirable not to store data in the RFID tag as much as possible, and in particular, it is preferable not to store data dedicated to rewritable sheets.

  In addition, in the printer control system described in Patent Document 1, only the usage conditions of the leuco light card are confirmed. However, when an RFID tag is attached, the rewriting is comprehensively performed after confirming the usage conditions of the RFID tag. It is desirable to be able to judge whether it is possible. Further, the printer control system described in Patent Document 1 outputs use stop information indicating use stop to the rewrite area of the leuco light card that is determined to have reached the limit number. For this reason, there is a possibility that accurate recognition cannot be performed, such as blurring due to reaching the limit number of times. In addition, if only the use stop information is output to the leuco light card that has been used, there is a possibility that a security problem may occur such that the information held so far is read after discarding.

  Therefore, the present invention enables to present a rewritable sheet associated with a wireless information medium that should be deactivated safely and securely without storing information for determining whether or not rewriting is possible in the associated wireless information medium. With the goal.

  A rewritable sheet management system according to the present invention is a rewritable sheet management system that manages a rewritable sheet that can be printed a plurality of times on a surface and is associated with a wireless information medium on which data is read and written wirelessly. Management means (for example, the center computer 20) that manages usage information indicating the usage frequency and usage period, and determination means (for example, a control unit) that determines whether or not the rewritable sheet can be rewritten based on the usage information stored in the management means 104), data rewriting means (for example, RFID reader / writer 103) for rewriting data stored in the wireless information medium attached to the rewritable sheet according to the determination result by the determination means, and the rewritable sheet according to the determination result by the determination means. Information printed on the surface A data rewriting unit that erases data stored in a wireless information medium attached to the rewritable sheet when the determination unit determines that rewriting is impossible. The print rewriting means is characterized by erasing the information printed on the surface of the rewritable sheet when the judgment means judges that rewriting is impossible.

  In addition, the rewritable sheet management system, when the determination unit determines that the rewritable sheet is not rewritable, a conveyance unit (for example, tag input / output) that conveys the rewritable sheet to a disposal discharge unit different from the discharge unit that discharges the rewritten rewritable sheet Part 101) may be provided.

  Further, the data rewriting means deletes data stored in the wireless information medium attached to the rewritable sheet when the judging means judges that rewriting is impossible, and then indicates data indicating that the rewritable sheet is to be discarded. You may write.

  The rewritable sheet management system further includes identification information reading means for reading identification information for identifying the rewritable sheet from a wireless information medium attached to the rewritable sheet, and the management means corresponds to the identification information and usage information of the rewritable sheet. Use information storage means (for example, database 203) to be stored, and the determination means corresponds to the identification information read by the identification information reading means among the use information stored in the use information storage means by the management means. Whether or not the rewritable sheet can be rewritten may be determined based on the usage information.

  In addition, the management unit may store usage information including at least the number of times data can be written and the number of times data can be written to the wireless information medium attached to the rewritable sheet, and the number of times that the surface of the rewritable sheet can be printed and the number that can be printed.

  The management means may store use information including at least the use start date and time and the use durability time of the rewritable sheet.

  The rewritable sheet management system stores identification information for identifying a rewritable sheet and usage information indicating the usage frequency and usage period of the rewritable sheet in association with each other, and retrieves usage information corresponding to the identification information. (For example, the database 203, the center control unit 202) and a printer device (for example, the RFID-attached rewritable sheet printer 10) that is connected to the database via a communication network and rewrites the rewritable sheet. Identification information reading means (RFID reader / writer 103) for reading identification information stored in a wireless information medium attached to the rewritable sheet, and usage information for searching the database for usage information corresponding to the identification information read by the identification information reading means Search required Means (for example, control unit 104), and determination means (for example, control unit 104) for determining whether or not the rewritable sheet identified by the read identification information can be rewritten based on the usage information searched in the database. According to the determination result by the determination means, data rewriting means (for example, RFID reader / writer 103) for rewriting data stored in the wireless information medium attached to the rewritable sheet, and printing on the surface of the rewritable sheet according to the determination result by the determination means Print rewriting means (for example, the rewritable sheet rewriting unit 102) for rewriting the read information, and use information update request means for updating the use information corresponding to the read identification information in the database according to the determination result by the determination means. The data rewriting means is written by the judging means. When it is determined that rewriting is not possible, the data stored in the wireless information medium attached to the rewritable sheet is erased, and the print rewriting means is printed on the surface of the rewritable sheet when the judging means determines that rewriting is not possible. Information may be deleted.

  The printer device according to the present invention is a printer device that can rewrite a rewritable sheet that can be printed a plurality of times on the surface and that is accompanied by a wireless information medium in which data is read and written wirelessly, and uses the rewritable sheet. It is connected to a database that stores usage information indicating the frequency and usage period, and is attached to the rewritable sheet according to the judgment means for judging whether or not the rewritable sheet can be rewritten based on the usage information stored in the database. Data rewriting means for rewriting the data stored in the wireless information medium, and print rewriting means for rewriting the information printed on the surface of the rewritable sheet according to the determination result by the determination means. If it is determined that rewriting is not possible, The data stored in the wireless information medium attached to the rewritable sheet is erased, and the print rewriting means erases the information printed on the surface of the rewritable sheet when the judging means judges that rewriting is impossible. To do.

  A rewritable sheet management method according to the present invention is a rewritable sheet management method for managing a rewritable sheet that can be printed a plurality of times on a surface and is associated with a wireless information medium on which data is read and written wirelessly. Based on the usage information indicating the usage frequency and usage period of the sheet, it is determined whether or not the rewritable sheet can be rewritten. If the determination result is not rewritable, the data stored in the wireless information medium attached to the rewritable sheet is erased. When the determination result cannot be rewritten, the information printed on the surface of the rewritable sheet is erased.

  Further, the rewritable sheet management program according to the present invention is a rewritable sheet management program for managing a rewritable sheet that can be printed a plurality of times on the surface and is associated with a wireless information medium on which data is read and written wirelessly. Then, based on the usage information indicating the usage frequency and usage period of the rewritable sheet, the computer determines whether the rewritable sheet can be rewritten, and if the determination result is non-rewritable, the wireless information attached to the rewritable sheet Processing for erasing data stored on the medium and processing for erasing information printed on the surface of the rewritable sheet when the determination result is not rewritable are executed.

  According to the present invention, since it is possible to determine whether or not rewriting is possible based on usage information of the rewritable sheet managed by the management means, extra information is stored in the wireless information medium associated with the rewritable sheet associated with the wireless information medium. There is no need. If it is determined that rewriting is not possible, the information held in the RFID-attached rewritable sheet before rewriting can be erased and transported to a disposal transport port. Is not likely to occur, and there is no possibility of misrecognizing whether it should be discarded. Therefore, it is possible to present the rewritable sheet associated with the wireless information medium that should be stopped safely and reliably without storing the information for determining whether or not rewriting is possible in the associated wireless information medium.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a rewritable sheet issuing system that issues a rewritable sheet by applying the rewritable sheet management system according to the present embodiment. In the rewritable sheet issuance system shown in FIG. 1, an RFID-attached rewritable sheet printer 10 and a center computer 20 are connected via a communication network such as the Internet. The RFID rewritable sheet printer 10 includes a tag input / output unit 101, a rewritable sheet rewriting unit 102, an RFID reader / writer 103, a control unit 104, and a communication unit 105. The center computer 20 includes a center communication unit 201, a center control unit 202, and a database 203.

  The RFID-attached rewritable sheet printer 10 communicates with the center computer 20 to determine whether or not the inserted RFID-attached rewritable sheet can be rewritten. According to the determination result, the display content or the stored content is rewritten or discarded. Process.

  As the rewriting process, for example, product information separately input on the rewritable sheet may be printed, and the product information may be stored in the RFID tag. In addition, as the disposal process, for example, the display content of the RFID-attached rewritable sheet and the product information stored in the attached RFID tag are erased, and the normal discharge port provided in the RFID-attached rewritable sheet printer 10 is used. Paper may be discharged from another paper discharge port for disposal. Alternatively, the display contents of the RFID-attached rewritable sheet and the product information stored in the attached RFID tag may be erased, and information indicating that the information may be discarded may be stored in the RFID tag. In such a case, after being ejected from the RFID-attached rewritable sheet printer 10, it is possible to sort using a device or the like that sorts based on information stored in the RFID tag.

  In this embodiment, “attaching an RFID tag to a rewritable sheet” means that the RFID tag is not only attached to the surface of the rewritable sheet but also attached to the back side or built in. Is the state clearly attached to the rewritable seat. Note that the RFID tag does not have to be in a tag shape, and it is sufficient that the function of the RIFD tag (a function as a wireless information medium for reading and writing information wirelessly) can be realized.

  The tag input / output unit 101 detects the inserted RFID-attached rewritable sheet and, in accordance with an instruction from the control unit 104, uses the conveyance path in the RFID-attached rewritable sheet printer 10 to input the RFID-attached rewritable sheet on the entrance side (feed). The paper is transported from the paper mouth to the exit side (paper exit). Specifically, the tag input / output unit 101 is a conveyance mechanism unit (for example, a roller conveyance mechanism unit) provided in the RFID-attached rewritable sheet printer 10.

  The rewritable sheet rewriting unit 102 rewrites (erases and prints) the rewritable sheet part of the RFID-attached rewritable sheet in accordance with an instruction from the control unit 104. The RFID reader / writer 103 reads and rewrites (erases and writes) the content stored in the RFID tag attached to the RFID-attached rewritable sheet according to the instruction of the control unit 104.

  The control unit 104 operates according to the control program and performs overall control of the RFID-attached rewritable sheet printer 10. Specifically, the control unit 104 controls the RFID reader / writer 103 to read the identification information stored in the RFID tag with respect to the inserted RFID-attached rewritable sheet, and reads the identification information stored in the RFID tag via the communication unit 105. Information is exchanged between them and whether or not rewriting is possible is determined. In addition, if rewriting is possible according to the determination result, the control unit 104 controls the rewritable sheet rewriting unit 102 and the RFID reader / writer 103 to perform rewriting processing of the RFID rewritable sheet. If the rewritable sheet is not rewritable, the rewritable sheet rewriting unit 102 and the RFID reader / writer 103 are controlled to discard the RFID rewritable sheet. The communication unit 105 communicates with the center computer 20 via a communication network.

  The RFID-attached rewritable sheet printer 10 is, for example, a combination of a rewritable printer capable of network communication and printing / erasing on a rewritable sheet, and an RFID reader / writer capable of reading / writing information from / to an RFID tag. A printer (for example, an RFID rewritable printer).

  The center computer 20 manages information used for determining whether or not rewriting is possible, such as the number of times each RFID-attached rewritable sheet is used. The center communication unit 201 communicates with the RFID-attached rewritable sheet printer 10 via a communication network. The center control unit 202 performs overall control of the center computer 20. Specifically, the center control unit 202 searches the database 203 based on the identification information for identifying the RFID-attached rewritable sheet received from the RFID-attached rewritable sheet printer 10, and uses information used for determining whether or not rewriting is possible. get. Then, the information acquired via the center communication unit 201 is transmitted to the requesting RFID-attached rewritable sheet printer 10. In addition, the center control unit 202 updates information indicating the usage state of the rewritten RFID-attached rewritable sheet stored in the database 203 as necessary.

  The database 203 is a database that stores information used to determine whether or not the RFID-attached rewritable sheet issued by the system can be rewritten. For example, the database 203 stores the number of times the RFID-related rewritable sheet is used and the number of rewritable times in association with the identification information of each RFID-related rewritable sheet.

  The center computer 20 is an information processing device such as a server device provided with a database, for example, and is realized by a hardware storage device and communication device, and a CPU that operates according to a program. The center computer 20 may be a database server that searches for information and updates information in accordance with a request received via a communication network.

  Next, the operation of the present embodiment will be described. FIG. 2 is a flowchart showing an example of the operation of the RFID-attached rewritable sheet printer 10 in the RFID-attached rewritable sheet issuing system according to the present embodiment. In FIG. 2, the expression “tag” represents a tag-shaped RFID-attached rewritable sheet, such as a price tag using an RFID-attached rewritable sheet.

  First, the RFID-attached rewritable sheet to be rewritten is input by the tag input / output unit 101 of the RFID-attached rewritable sheet printer 10 (step S1). When the RFID-attached rewritable sheet is inserted, the tag input / output unit 101 of the RFID-attached rewritable sheet printer 10 detects the insertion. When the insertion of the RFID-attached rewritable sheet is detected, the control unit 104 of the RFID-attached rewritable sheet printer 10 controls the RFID reader / writer 103 and is stored in the RFID tag attached to the inserted RFID-attached rewritable sheet. The identification information (tag ID) for identifying the RFID-attached rewritable sheet is read (step S2).

  For example, the control unit 104 outputs a read command to the RFID reader / writer 103 to read information from the RFID tag in the communication area. The RFID reader / writer 103 receives the read command, reads information from the RFID tag wirelessly, and outputs the read information to the control unit 104.

  Next, the control unit 104 controls the communication unit 105 to perform communication with the center computer 20 to determine whether the inserted RFID-attached rewritable sheet can be rewritten (step S3). For example, the control unit 104 transmits the read identification information to the center computer 20 via the communication network.

  The center computer 20 receives identification information from the RFID-attached rewritable sheet printer 10. The center control unit 202 of the center computer 20 uses the received identification information as a search key, and information for determining whether or not rewriting is possible from the information of the corresponding RFID-attached rewritable sheet from the database 203 (for example, rewritable with the number of times of use) Number of times). Then, the center communication unit 201 is controlled to return the acquired information for determining whether or not rewriting is possible to the RFID-attached rewritable sheet printer 10 via the communication network.

  The RFID-attached rewritable sheet printer 10 receives information for determining whether or not the inserted RFID-attached rewritable sheet can be rewritten from the center computer 20. The control unit 104 of the RFID-attached rewritable sheet printer 10 determines whether or not the RFID-attached rewritable sheet can be rewritten based on the received information (step S4). For example, it is determined that rewriting is possible when the number of times of use does not exceed the number of possible rewritings, and it is determined that rewriting is not possible otherwise. Here, the rewritable number of times includes the rewritable sheet rewritable number (printable number of times) and the RFID tag rewritable number (data writable number). In addition, when rewriting to the rewritable sheet and rewriting to the RFID tag are not performed at the same time, the number of times to use the rewritable sheet and the number of times to use the RFID tag are managed separately, and Use it to judge.

  If the result of the determination is that rewriting is possible (Yes in step S4), the control unit 104 controls the rewritable sheet rewriting unit 102 and the RFID reader / writer 103 based on the separately input rewriting data, so that the RFID-attached rewritable is controlled. A sheet rewriting process is performed (step S5). For example, the control unit 104 outputs information indicating the display content of the rewritable sheet included in the rewritable data input from the operation terminal for the RFID-attached rewritable sheet printer 10 to the rewritable sheet rewriting unit 102 and also performs a rewrite instruction. Is output. In accordance with an instruction from the control unit 104, the rewritable sheet rewriting unit 102 prints product information or the like on the rewritable sheet portion of the inserted RFID-attached rewritable sheet. For example, the control unit 104 outputs information indicating the storage contents of the RFID tag included in the rewriting data to the RFID reader / writer 103 and outputs a rewriting instruction. The RFID reader / writer 103 writes data such as product information in an RFID tag attached to the inserted RFID rewritable sheet according to an instruction from the control unit 104.

  In addition, when the control unit 104 rewrites the RFID-attached rewritable sheet, the control unit 104 updates the information indicating the use state of the RFID-attached rewritable sheet managed by the center computer 20. The number of times of use is transmitted to the center computer 20. In addition, when the center computer 20 manages including the rewritten information, the center computer 20 may transmit the information.

  Further, the center computer 20 determines whether or not rewriting is possible based on information acquired from the database 203, transmits the determination result to the RFID-attached rewritable sheet printer 10, and information indicating the use state stored in the database 203 Can also be updated. In such a case, the control unit 104 of the RFID-attached rewritable sheet printer 10 may perform the rewriting process or the discarding process according to the received determination result.

  Then, the control unit 104 outputs the rewritten RFID-attached rewritable sheet from the tag input / output unit 101 (step S6). For example, the control unit 104 controls the tag input / output unit 101 to discharge paper from a normal paper discharge port.

  On the other hand, if the result of the determination is that rewriting is not possible (No in step S4), the control unit 104 controls the rewritable sheet rewriting unit 102 and the RFID reader / writer 103 to perform the disposal process of the RFID rewritable sheet (step S7). , S8). For example, the control unit 104 outputs an erasure instruction to the rewritable sheet rewriting unit 102. The rewritable sheet rewriting unit 102 erases product information and the like printed on the rewritable sheet part (rewritable area) of the inserted RFID-attached rewritable sheet according to an instruction from the control unit 104. Further, the control unit 104 outputs an erasure instruction to the RFID reader / writer 103, for example. The RFID reader / writer 103 erases data such as product information stored in the rewritable storage area of the RFID tag attached to the inserted RFID rewritable sheet according to the instruction from the control unit 104. Alternatively, for example, the control unit 104 outputs a rewrite instruction to information indicating discard to the RFID reader / writer 103, and the RFID reader / writer 103 deletes product information from the RFID tag according to the rewrite instruction and then displays data indicating discard. You may write.

  In addition, when the RFID-attached rewritable sheet is not rewritable, the control unit 104 may transmit information to the center computer 20 to discard it. The center computer 20 updates the information in the database 203 based on the information indicating the use state including the information to be discarded received from the RFID-attached rewritable sheet printer 10.

  Then, the control unit 104 outputs the RFID-attached rewritable sheet to be discarded from the tag input / output unit 101 (step S8). The control unit 104 controls the tag input / output unit 101 for an RFID-attached rewritable sheet that is determined to be non-rewritable so that it can be discharged from a disposal discharge port different from a normal discharge port. Good.

  In this example, the case where the number of times of use and the number of rewritable times is used as information for determining whether or not the rewritable sheet with RFID is rewritable has been described as an example, but the present invention is not limited thereto. For example, if the RFID tag is a battery built-in type, it is possible to manage based on not only the number of times of use but also the elapsed time since the start of use. In such a case, the information stored in the database 203 may include the use start date and time and the battery durability time.

  As described above, according to the present embodiment, information for determining whether or not the RFID rewritable sheet can be rewritten, such as the number of uses, is managed on the center side, and therefore it is necessary to store extra information in the RFID tag. Absent. If it is determined that rewriting is not possible, the information held by the RFID-attached rewritable sheet before rewriting (surface printing and storage) will be erased and then discharged from the discharge outlet for disposal. There is no possibility of a security problem such as being read, and there is no possibility of being misrecognized due to blurring or the like by printing on an RFID-attached rewritable sheet to be discarded. Therefore, it is possible to present an RFID-attached rewritable sheet that should be stopped using safely and reliably without storing information for determining whether or not rewriting is possible in the RFID tag.

  In addition, this system is not only operated for reusing the tag in a company or the like that uses the RFID-attached rewritable sheet, but may be an operation method as shown in FIG. 3, for example. FIG. 3 is an explanatory diagram showing an operation example of the RFID rewritable sheet issuing system according to the present embodiment. In the operation method shown in FIG. 3, the tag using company 302 sends the used RFID-attached rewritable sheet and new data to be written when it is reused to the tag issuer 301. The tag issuer 301 has an RFID-attached rewritable sheet printer 10 and a center computer 20, and the center computer 20 manages identification information of the RFID-attached rewritable sheet issued to the requesting company. It shall be.

  In the tag issuer 301, the RFID attached rewritable sheet issuance system is operated by using the RFID attached rewritable sheet and new data sent from the tag user 302, and the RFID attached rewritable sheet is reused and rewritten. The rewritable sheet with RFID is sent to the requesting tag user 302.

  An operation method is also conceivable in which the tag issuer 301 manages RFID-related rewritable sheets used by a plurality of companies and subcontracts the reuse processing of RFID-related rewritable sheets from a plurality of companies.

  Further, the present invention can also be implemented as an RFID rewritable sheet usage confirmation system as shown in FIG. FIG. 4 is a block diagram showing a configuration of an RFID-attached rewritable sheet usage confirmation system according to the present invention. The RFID-accompanying rewritable sheet usage confirmation system shown in FIG. 4 is a system that performs a rewritability determination in the RFID-accompanying rewritable sheet issuing system shown in FIG. 1 and a sort output according to the determination result.

  Accordingly, the RFID-attached rewritable sheet printer 10 is different from the RFID-attached rewritable sheet issuing system shown in FIG. 1 in that the RFID-attached rewritable sheet use confirmation terminal 11 is used. The RFID-attached rewritable sheet use confirmation terminal 11 is an information processing apparatus that includes an RFID reader 113 that excludes the rewritable sheet rewriting unit 102 from the RFID-attached rewritable sheet printer 10 and that has a writer function instead of the RFID reader / writer 103. is there. The RFID-attached rewritable sheet usage confirmation terminal 11 may be, for example, a personal computer connected to an RFID reader device.

  The operation of the RFID-attached rewritable sheet usage confirmation system is the same as that of the RFID-attached rewritable sheet issuing system except that the rewriting process is not performed when it is determined that rewriting is possible.

  The present invention can be suitably applied to uses such as billboards in production processes of factory buildings and price tags attached to products in the apparel industry.
