Description

[Technical Field]

[0001] The technical field disclosed in this specification relates to a print monitoring system for monitoring prints, a wireless tag, and a print monitoring program installed in a mobile terminal. [Background technology]

[0002] In recent years, the spread of teleworking and other trends has led to an increasing demand for off-site printing. Off-site printing poses security issues, such as the risk of information leakage due to loss of printed materials. Systems for managing printed materials are known as one solution to this issue. For example, Patent Document 1 discloses a document management system having a multifunction peripheral, a shredder, and a server. When printing a document, the multifunction peripheral outputs a printed material bearing a two-dimensional code containing a document ID, and the server stores the document ID. When disposing of the printed material, the shredder reads the two-dimensional code, and then disposes of the printed material. The server is notified of the document ID contained in the read two-dimensional code. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0011] (First embodiment) An embodiment of a print management system according to the present invention will be described in detail below with reference to the accompanying drawings.

[0012] Recently, amid growing calls for work style reform aimed at securing human resources and improving productivity, the number of companies introducing "telework" has rapidly increased. Telework can be divided into "teleworking from home," "teleworking from a satellite office," and "teleworking" depending on the location of the work, and it is believed that many companies have introduced "teleworking from home" as a form of "telework." Incidentally, when "teleworking from home," for example, employees work from home, many printed materials containing trade secrets may be printed at the employee's home, and such printed materials containing trade secrets must be properly managed until they are discarded. The print management system according to this embodiment is a system for properly managing printed materials printed at, for example, an employee's home until they are discarded.

[0013] FIG. 1 is an explanatory diagram showing the schematic configuration of a printed matter management system according to this embodiment, which will be described in detail below with reference to the drawings. As shown in FIG. 1, the printed matter management system 100 of this embodiment includes a personal computer (hereinafter referred to as a "PC") 2 and a printer 4 installed at a telework location, for example, an employee's home; a management terminal device 5, a printer 6, and a shredder 7 installed at the employee's workplace, for example, the office where the employee normally works; a cloud server 9; a monitoring device 10 carried by the employee; an electronic tag 11; and smartphones 200 carried by multiple other employees. The printed matter management system is an example of a printed matter monitoring system. The management terminal device 5 and the cloud server 9 are examples of servers. The electronic tag 11 is an example of a wireless tag.

[0014] Furthermore, PC 2 is connected to cloud server 9 via, for example, an internet line 12 so that they can communicate with each other. Also, management terminal device 5, printer 6, and shredder 7 are connected to each other via a local area network (hereinafter referred to as "LAN") 13 installed in the office so that they can communicate with each other. Also, LAN 13 is connected to internet line 12, and therefore management terminal device 5 and shredder 7 are connected to cloud server 9 via LAN 13 and internet line 12 so that they can communicate with each other.

[0015] In this embodiment, the telework destination is the employee's home, but is not limited to this. For example, it could be a satellite office, a hotel, or a vacation home. In this embodiment, the telework destination is the employee's workplace, for example, the office where the employee normally works, but is not limited to this. In other words, it can be anywhere as long as it is communicatively connected to the cloud server 9 and the shredding device 7 is installed, for example, it could be a satellite office provided by the employer. In this embodiment, the cloud server 9 is connected to the Internet line 12, but is not limited to this. For example, it could be connected to a LAN 13.

[0016] Fig. 2 is a schematic diagram showing the electrical configuration of a personal computer and a cloud server, which will be described in detail below with reference to the drawings. As shown in Fig. 2, PC 2 has a control unit 20 consisting of a CPU 21, a ROM 22, and a RAM 23, a storage device 24, an operation display unit 26, a network interface 27, and a USB interface 28. ROM 22 stores a startup program for starting up PC 2, etc. RAM 23 is used as a working area when various processes are executed, or as a storage area for temporarily storing data.

[0017] The storage device 24 is configured, for example, with a semiconductor memory such as a flash memory or an HDD (Hard Disk Drive). The storage device 24 also incorporates an operating system (hereinafter referred to as "OS") 30, an application program (hereinafter referred to as "app") 31, a printer driver 32, an electronic tag app 33, and a virtual driver 34. The OS 30 is, for example, Windows (registered trademark), but may also be any of macOS (registered trademark), iOS (registered trademark), Android (registered trademark), and Linux (registered trademark).

[0018] The application 31 is a program for executing processing for a specific purpose, and specifically, for example, is a program that can accept an image to be used as image data, accept editing of the image, accept print settings, specify the printer 4 to be used for printing, accept an instruction to execute printing, etc. via the operation display unit 26. The application 31 may also include various application programs such as a word processing program, a spreadsheet program, a web browser, etc.

[0019] The printer driver 32 is a program corresponding to the model of the printer 4, and communicates with the printer 4 via the USB interface 28 to control the operation of the printer 4. The printer driver 32 is started, for example, when an instruction to set the properties of the printer 4 is received while the printer 4 is specified in the application 31 or the like.

[0020] Furthermore, when printer driver 32 receives print instruction information from OS 30, it acquires image data specified in the print instruction information and generates print data based on the acquired image data. Then, printer driver 32 transmits a print job including the generated print data and the acquired print settings to printer 4 via print queue 301 and an output port (not shown) managed by OS 30.

[0021] The electronic tag application 33 is launched by an employee (user), and when launched, it constantly monitors the status of print jobs in the print queue 301, and when a print job is output from the printer driver 32 to the print queue 301, it acquires the print job.

[0022] In addition, the electronic tag application 33 generates two-dimensional barcode print data for printing the two-dimensional barcode 16 shown in Figure 1 on the printing paper 14 and print ID print data for printing the print ID 17 on the printing paper 14, and then inserts the two-dimensional barcode print data and print ID print data into the print data of the acquired print job.

[0023] Furthermore, when printing is completed by the printer 4, the electronic tag application 33 generates the print log information 18 shown in FIG.

[0024] The virtual driver 34 is started by the electronic tag application 33 and transmits the print job generated by the electronic tag application 33 to the printer 4 via the output port.

[0025] The electronic tag application 33 and the virtual driver 34 are downloaded in advance by the employee (user) from the cloud server 9 to the PC 2 and stored in the storage device 24. Another possible installation method is to insert a recording medium, such as a USB memory or CD-ROM, on which the electronic tag application 33 and the virtual driver 34 are stored into the PC 2, and then store the virtual driver 34 read from the recording medium in the storage device 24. When the electronic tag application 33 and the virtual driver 34 are stored in the storage device 24, the user ID 181 and terminal ID 182 in the print log information 18 shown in Fig. 3 are set and stored by the employee (user).

[0026] In this embodiment, the virtual driver 34 is configured as a separate entity from the printer driver 32, but if, for example, the manufacturer of the printed matter management system 100 is the same as the manufacturer of the printer 4, it is possible to integrate the functions of the virtual driver 34 into the printer driver 32. In this embodiment, since the manufacturer of the printed matter management system 100 is different from the manufacturer of the printer 4, the virtual driver 34 is configured as a separate entity from the printer driver 32.

[0027] The CPU 21 executes various processes according to programs read from the ROM 22 or the storage device 24 .

[0028] The operation display unit 26 is composed of, for example, a display device and a keyboard, which are provided integrally with the housing of the PC 2. The display device displays necessary information, and the keyboard accepts input from the user. The keyboard may be composed of a touch panel provided integrally on the display device.

[0029] In this embodiment, the PC 2 is configured as a notebook personal computer, but it may also be configured as a desktop personal computer. In this case, the PC 2 is provided with an interface for connecting devices that realize the functions of the operation display unit 26, specifically, a keyboard, a mouse, a display, etc. Also, the PC 2 may be configured as a smartphone, a tablet, and a printer 4.

[0030] The network interface 27 is an interface including a communication circuit for communicating with the cloud server 9 via the internet line 12 .

[0031] The USB interface 28 is an interface that includes a communication circuit for communicating with the printer 4 via a USB cable. Therefore, by connecting a USB cable between the USB interface 41 of the printer 4 and the USB interface 28, the PC 2 and the printer 4 can communicate via a wired connection.

[0032] The image forming unit (not shown) of printer 4 prints image 15, two-dimensional barcode 16, and print ID 17 on print paper 14 as a printing target, based on the print data, two-dimensional barcode print data, and print ID print data sent from PC 2, as shown in FIG. 1. The image forming unit may use any of the following image forming methods: thermal printing, electrophotography, inkjet printing, and other methods. The image forming unit may use an image forming method capable of color printing, or an image forming method that supports only monochrome printing.

[0033] In this embodiment, an inkjet printing method compatible with color printing is used as the image forming unit of the printer 4. Furthermore, plain paper and photo paper are used as the printing paper 14 to be printed on.

[0034] 2, the cloud server 9 has a CPU 91, a ROM 92, a RAM 93, a storage unit 94, an operation display unit 96, and a network interface 95. The ROM 92 stores a startup program for starting up the cloud server 9. The RAM 93 is used as a work area when various processes are executed, or as a storage area for temporarily storing data. The management terminal device 5 and the cloud server 9 are examples of servers.

[0035] The storage unit 94 is configured by, for example, an HDD or flash memory, and stores various processing programs and data such as the print log information 18 shown in FIG.

[0036] The CPU 91 executes various processes in accordance with programs read from the ROM 92 or the storage unit 94 .

[0037] The operation display unit 96 is configured, for example, by a display device and a touch panel arranged on the display device, etc. The display device displays necessary information, and the touch panel accepts inputs from the user.

[0038] Note that the configuration of the operation and display unit 96 may be such that a device for realizing the functions of the operation and display unit 96 is provided separately from the housing of the cloud server 9. In this case, the cloud server 9 has an interface for connecting a device for realizing the functions of the operation and display unit 96, specifically, a keyboard, a mouse, a display, etc.

[0039] 3 is an explanatory diagram showing a schematic configuration of print log information 18. Print log information 18 is made up of one or more records, and each record is made up of a user ID 181, a terminal ID 182, a document ID 183, a page ID 184, a printing date 185, disposal / loss information 186, a disposal date 187, an electronic tag ID 188, loss time information 189, and discovery time information 190. The document ID 183 and page ID 184 make up a printed matter ID 17. The print log information 18 is an example of printed matter information.

[0040] The user ID 181 may be an employee code of the employee (user) at the company. The terminal ID 182 may be the user name or IP address of the PC 2. The document ID 183 is assigned as a serial number to printed matter composed of print sheets 14 printed using the PC 2, in the order of printing, for each file name. The page ID 184 indicates the page number of the printed matter for each file name. The printing date 185 indicates the date of printing using the PC 2. The disposal / loss information 186 is information indicating, for each page of the printed matter, whether the printed matter printed using the PC 2 has been shredded by the shredder 7 (whether disposal has been completed), whether it is in transport, or whether it is lost. The disposal / loss information 186 is an example of transport status information. In transport is an example of a first value, and lost is an example of a second value.

[0041] Furthermore, the disposal date 187 indicates the date on which the printed matter printed using the PC 2 was shredded by the shredder 7. Furthermore, the electronic tag ID 188 can be set by the employee (user) when the monitoring device 10 carried by the employee (user) is connected to the electronic tag 11. The employee (user) can set any code as the electronic tag ID 188. Furthermore, the loss information 189 is made up of the location information of the monitoring device 10 and the disconnection time when the connection between the monitoring device 10 and the electronic tag 11 is disconnected. The discovery information 190 is made up of the finder ID made up of the user ID 181 of the employee carrying the monitoring device 10 or smartphone 200 that discovered the lost electronic tag 11, and the location information and discovery time of the monitoring device 10 or smartphone 200 when it was discovered.

The OS 55 is, for example, Windows (registered trademark), but may also be any of macOS (registered trademark), iOS (registered trademark), Android (registered trademark), and Linux (registered trademark).

[0044] The electronic tag system application 56 is a program for integrating the entire printed matter management system 100. Therefore, an administrator who is permitted to operate the management terminal device 5 can view the print log information 18 stored in the cloud server 9 by starting the electronic tag system application 56. This allows the administrator to grasp and manage the transportation / disposal status of the printing paper 14 in real time.

[0045] Furthermore, when the electronic tag system application 56 receives a request to register a carried material or a lost material from the monitoring device 10, it registers the carried material or the lost material in the print log information 18 of the cloud server 9. Furthermore, when the bag 19 is lost, it sets the smartphone 200 to search for the bag 19. Furthermore, when it receives discovery information from the smartphone 200, it notifies the discovery information to the monitoring device 10. Furthermore, the electronic tag system application 56 may include various application programs such as a word processing program, a spreadsheet program, a web browser program, etc.

[0046] The printing cost management application 57 can manage, for each employee (user), the printing cost according to the number of sheets of printing paper 14 that the employee (user) printed at home using the printer 4 and that were shredded by the shredder 7, based on the printing log information 18.

[0066] The OS 112 is iOS (registered trademark), but may also be any of Windows (registered trademark), macOS (registered trademark), Linux (registered trademark), and Android (registered trademark), for example.

[0067] The monitoring application 113 can be used by, for example, being downloaded from the cloud server 9 via the Internet line 12 and installed on the monitoring device 10. Note that the download may be performed from the management terminal device 5 instead of the cloud server 9.

[0068] Furthermore, when the monitoring device 10 and the electronic tag 11 are connected via the second communication IF 109, the monitoring application 113 can set the electronic tag ID 188 of the connected electronic tag 11.

[0069] Furthermore, when the monitoring application 113 reads the two-dimensional barcode 16 printed on the printing paper 14 via the camera 106, it can decode the two-dimensional barcode 16 and acquire the printed matter ID 17. Furthermore, the monitoring application 113 stores the set electronic tag ID 188 and the acquired printed matter ID 17 in the storage device 111.

[0070] Furthermore, the monitoring application 113 can upload the set electronic tag ID 188 and the acquired printed matter ID 17 to the cloud server 9 via the first communication IF 105. Therefore, the cloud server 9 updates the electronic tag ID 188 in the print log information 18 based on the uploaded printed matter ID 17.

[0071] Furthermore, the monitoring application 113 can transmit to the management terminal device 5 a request for registering a carried document when the bag 19 is transported, or a request for registering a lost document when the bag 19 is lost. Furthermore, when the lost bag 19 is found by the smartphone 200, the employee (user) is notified of the discovery information via the user IF 107. The monitoring application 113 may include various application programs such as a word processing program, a spreadsheet program, a web browser program, etc.

[0072] Furthermore, when an employee (user) brings the monitoring device 10 and the electronic tag 11 close to each other within a range of approximately 10 m to 20 m while the monitoring application 113 is running, the monitoring device 10 and the electronic tag 11 can be paired via the second communication IF 109. Thereafter, when the monitoring device 10 and the electronic tag 11 move away from each other beyond the range of 10 m to 20 m, communication between the electronic tag 11 and the monitoring device 10 is interrupted. Then, the monitoring device 10 generates an alarm via the alarm device 110. This causes the monitoring device 10 to notify the employee (user) that the electronic tag 11 has moved away from the monitoring device 10 by more than a predetermined distance, i.e., that it has been lost.

[0073] 1 , the electronic tag 11 is a so-called smart tag, specifically, for example, "Air Tag" (registered trademark) from Apple (registered trademark), etc. The electronic tag 11 has an interface (not shown) conforming to a short-range wireless communication standard configured by Bluetooth, and is configured to be able to communicate with and pair with the monitoring device 10 and the smartphone 200 via Bluetooth Low Energy (BLE).

[0074] The electronic tag 11 also includes a storage unit (not shown) and can store the electronic tag ID 188 and the printed matter ID 17 transmitted from the monitoring device 1.

[0075] Returning to FIG. 1, the smartphone 200 is configured, for example, by a smartphone (smart phone) or a tablet, and the smartphone (smart phone) or tablet may be owned by an employee (user) or may be owned by the company where the employee works. In this embodiment, the employee (user) who owns the monitoring device 10 and the employee (user) who owns the smartphone 200 work for the same company. Furthermore, the smartphone 200 has the same configuration as the monitoring device 10 except that it is owned by a different person, so a detailed description will be omitted, but in the following description, the same reference numerals as those in the configuration of the monitoring device 10 will be used. Note that this is an example of a second mobile terminal.

[0076] FIG. 6 is a sequence diagram showing the steps of a printing process using a personal computer and a printer, which will be described in detail below with reference to the drawings. Note that in this specification, the operation of each program will be described without mentioning OS 30. That is, in the following description, a statement to the effect that "Program B controls Hardware C" may also mean that "Program B controls Hardware C using the API of OS 41." Also, the processing of CPU 21 according to instructions written in a program may be described in abbreviated terms. For example, it may be described as "performed by the CPU" or "performed by the program."

[0077] First, in FIG. 6, when an employee (user) starts the electronic tag application 33 prior to printing using the printer 4, the electronic tag application 33 constantly monitors the status of the print queue 301 (step 10 (hereinafter referred to as "T10")).

[0078] Next, the employee (user) issues a print instruction to the application 31 via the operation display unit 26 of the PC 2 (T11). In response, the application 31 generates image data of the image 15 created by the employee (user) using the application 31 (T12), and then outputs the generated image data to the printer driver 32 (T13).

[0079] The printer driver 32 then generates print data based on the acquired image data (T14), and outputs a print job including the generated print data and the acquired print settings to the print queue 301 managed by the OS 30 (T15).

[0080] The electronic tag application 33 constantly monitors the print queue 301 (T10), so when a print job is output from the printer driver 32 to the print queue 301, the electronic tag application 33 acquires the print job from the print queue 301 (T16).

[0081] Next, the electronic tag application 33 generates a document ID 183 and a page ID 184 as the printed matter ID 17 from the file name and page information extracted from the acquired print job. Next, as shown in Fig. 1, two-dimensional barcode print data for printing the two-dimensional barcode 16 encoding the printed matter ID 17 on the printing paper 14 and printed matter ID print data for printing the printed matter ID 17 on the printing paper 14 are generated, and then the two-dimensional barcode print data and printed matter ID print data are inserted into the print data of the acquired print job (T17).

[0082] Next, the electronic tag application 33 starts the virtual driver 34 (T18). When the virtual driver 34 is started, it sends the print data generated by the electronic tag application 33, i.e., the print data into which the two-dimensional barcode print data and the printed matter ID print data have been inserted, and a print job including print settings, etc., to the printer 4 (T19).

[0083] Next, the printer 4 that has received the print job prints on the printing paper 14, which is the printing target, based on the received print job (T20). As a result, as shown in Figure 1, an image 15, a two-dimensional barcode 16, and a print ID 17 are each printed on the printing paper 14.

[0084] When printing is completed, the printer 4 transmits a print completion notification to the application 31 (T21). This allows the employee (user) to recognize that printing has completed via the operation display unit 26 of the PC 2.

[0085] The printer 4 also transmits a print completion notification to the electronic tag application 33 (T22). Upon receiving the print completion notification, the electronic tag application 33 generates print log information 18 (T23), and then transmits the data of the generated print log information 18 to the cloud server 9 via the Internet line 12 (T24).

[0086] Next, the cloud server 9, which has received the data of the print log information 18, stores the received data of the print log information 18 in the storage unit 94 (T25). That is, the print log information 18 relating to the print paper 14 (printed matter) printed this time using the printer 4 is stored in the storage unit 94. In addition, the status of the disposal / loss information 186 in the currently received print log information 18 is updated to "disposal not completed" (T26).

[0087] Next, in the printed matter management system of this embodiment, printed matters printed by a printer 4 installed at a telework destination, for example, an employee's home, may contain confidential company information and must be properly managed and disposed of. To do this, the employee (user) places printed paper 14 (printed matters) in a bag 19 with an electronic tag 11 attached, and then transports the bag 19 to the office. After that, the printed paper 14 (printed matters) must be removed from the bag 19 and shredded by a shredding device 7.

[0088] Before an employee (user) transports the printing paper 14 (printed matter) stored in a bag 19 to the office, the employee (user) must first pair the monitoring device 10 with the electronic tag 11, and then use the monitoring device 10 to register the printing paper 14 (printed matter) to be transported in the cloud server 9.

[0089] That is, when an employee (user) selects the registration mode after starting the monitoring application 113 of the monitoring device 10, an electronic tag registration screen as shown in Fig. 7(A) is displayed on the user IF 107. In this state, when the employee (user) brings the monitoring device 10 and the electronic tag 11 close to each other within a range of approximately 10 m to 20 m and then touches the "Start registration" button 107A, the monitoring device 10 and the electronic tag 11 are connected via the second communication IF 109, and then the screen transitions to an electronic tag name setting screen as shown in Fig. 7(B).

[0090] Next, on the electronic tag name setting screen shown in Fig. 7(B), the employee (user) touches the keyboard 107B displayed on the user IF 107 to input the name of the electronic tag 11, i.e., the electronic tag ID 188. The electronic tag ID 188 can be any combination of the user ID 181, the printer ID of the printer 4, the user name or IP address of the PC 2, the document ID 183, the page ID 184, the printed matter ID 17, etc. Of course, it may be any code set by the employee (user). In this embodiment, the user ID 181 is set as the electronic tag ID 188.

[0091] Next, after inputting the name of the electronic tag 11, the employee (user) touches the "Continue" button 107C, which transitions to a printed matter registration screen as shown in Fig. 7(C). On this printed matter registration screen, the employee (user) touches the shutter 107D and uses the camera 106 to photograph the two-dimensional barcode 16 printed on the printing paper 14 (printed matter) that is currently being transported to the office. If there are multiple sheets of printing paper 14 (printed matter), the camera 106 is used to photograph the two-dimensional barcodes 16 on all of the printing paper 14 (printed matter). This process is an example of the acquisition process.

[0092] Next, after completing the photographing, when the employee (user) touches the "Continue" button 107E, the screen transitions to a registration screen for the printed matter management system, as shown in Fig. 7(D). Here, when the employee (user) touches the "Continue" button 107E, the monitoring device 10 decodes the read two-dimensional barcode 16 to obtain the printed matter ID 17, and then stores the printed matter ID 17 and the electronic tag ID 188 set by the employee (user) in the storage device 111. The monitoring device 10 also transmits the printed matter ID 17 and the electronic tag ID 188 stored in the storage device 111 to the cloud server 9.

[0093] Then, the cloud server 9, which has received the printed matter ID 17 and the electronic tag ID 188, stores the electronic tag ID 188 in the print log information 18 based on the printed matter ID 17. This completes the registration of the transported printing paper 14 (printed matter) in the printed matter management system 100.

[0094] The monitoring device 10 also transmits the printed matter ID 17 and the electronic tag ID 188 stored in the storage device 111 to the electronic tag 11, and the electronic tag 11 stores the received printed matter ID 17 and the electronic tag ID 188 in its storage unit. The monitoring device 10 may be configured to transmit all of the printed matter IDs 17 stored in the storage device 111, or may be configured to transmit only a portion of them, for example, the printed matter ID 17 of the printing paper 14 (printed matter) photographed first.

[0095] Next, in the printed matter management system 100 of this embodiment, when an employee (user) carries a bag 19 containing printing paper 14 (printed matter) to the office, the bag 19 can be monitored for loss using the monitoring device 10 and the electronic tag 11 attached to the bag 19. Also, if the bag 19 is lost, the bag 19 can be searched for using the electronic tag 11.

[0096] 8 and 9 are sequence diagrams showing the procedures for the monitoring process and search request process of the printed matter management system 100, which will be described in detail below with reference to the drawings. In the monitoring process and search process of the printed matter management system 100, the process in the monitoring device 10 is performed by the CPU 102 of the monitoring device 10 executing the monitoring application 113. The process in the management terminal device 5 is performed by the CPU 511 executing the RFID tag system application 56. The process in the smartphone 200 is performed by the CPU 102 of the smartphone 200 executing the monitoring application 113.

[0097] That is, in FIG. 8, when an employee (user) starts the monitoring application 113 of the monitoring device 10 and then selects the transport mode (T30), the monitoring device 10 sets the transport mode (T31).

[0098] The monitoring device 10 then outputs a transport material registration request to the management terminal device 5 (T32). The transport material registration request includes information indicating the transport material registration request, information indicating that the item is being transported (for example, "in transport"), the printed matter ID stored in the storage device 111, and setting information for the search mode in case of loss (in this embodiment, the full search mode). The transport material registration request is an example of a monitoring registration command. The processing of T32 is an example of a first transmission processing.

[0099] Furthermore, the management terminal device 5, which has received the transport material registration request, registers the transport material in the cloud server 9 (T33). That is, the cloud server 9 rewrites the corresponding discard / loss information 186 to "in transport" in the print log information 18 stored in the storage unit 94 based on the printed matter ID included in the transport material registration request. The processing of T33 is an example of storage processing.

[0100] Next, the management terminal 5 transmits a notification of completion of the transport mode setting to the monitoring device 10 (T34). Then, the monitoring device 10 displays on the user IF 107 a message indicating that the transport mode setting has been completed (T35), and notifies the employee (user) of this fact.

[0101] Next, the monitoring device 10 searches for devices that are outputting advertising signals, and transmits a pairing connection start request to the found electronic tag 11 (T36). The processing of T36 is an example of monitoring establishment processing. Then, the electronic tag 11 that has received the pairing connection start request stops outputting advertising signals and sets pairing information including its own electronic tag ID 188 (T37). Thereafter, the electronic tag 11 transmits a connection completion to the monitoring device 10. The connection completion includes the set pairing information. This completes pairing between the monitoring device 10 and the electronic tag 11.

[0102] Next, the employee (user) carries the bag 19 containing the printing paper 14 (printed matter) and moves toward the office (T39). During this movement, at regular intervals (for example, every one second to several seconds), the monitoring device 10 transmits a connection status confirmation request to the electronic tag 11 using the pairing information including the electronic tag ID 188 of the electronic tag 11 acquired in the process of T38 (T40). Furthermore, upon receiving the connection status confirmation request, the electronic tag 11 transmits an acknowledgement including the pairing information to the monitoring device 10 (T41).

[0103] Furthermore, upon receiving this confirmation response, the monitoring device 10 determines that the bag 19 containing the printing paper 14 (printed matter) is located near the employee (user) (within a range of approximately 10 to 20 meters). Note that the connection status confirmation request is an example of a confirmation signal, and the confirmation response is an example of a response signal. Furthermore, this determination process is an example of a confirmation process.

[0104] In this embodiment, the monitoring device 10 continues to check the connection status until the employee (user) arrives at the office carrying the bag 19 containing the printing paper 14 (printed matter), or until the employee (user) shreds the printing paper 14 (printed matter) using the shredder 7. When the employee (user) arrives at the office carrying the bag 19 containing the printing paper 14 (printed matter), or when the employee (user) has shredded the printing paper 14 (printed matter) using the shredder 7, the employee (user) inputs a disconnection command to the monitoring application 113 of the monitoring device 10. This disconnects the connection between the monitoring device 10 and the electronic tag 11, and therefore the checking processes of T40 and T41 also end.

[0105] Furthermore, if the employee (user) loses the bag 19 while traveling by leaving it on a moving object, for example, a train (T42), the distance between the monitoring device 10 and the electronic tag 11 will increase. For example, if the monitoring device 10 and the electronic tag 11 are separated by more than a range of approximately 10 to 20 meters, the electronic tag 11 will no longer be able to receive a connection status confirmation request from the monitoring device 10, and the monitoring device 10 will no longer be able to receive a confirmation response from the electronic tag 11. Therefore, communication between the monitoring device 10 and the electronic tag 11 will be cut off, and the monitoring device 10 will determine that the electronic tag 11 and the bag 19 have been lost. Furthermore, the electronic tag 11 will determine that it itself is in a lost state.

[0106] In this embodiment, loss is determined when communication between the monitoring device 10 and the electronic tag 11 is cut off, but this is not limiting. For example, loss may be determined when the radio wave intensity based on the response signals from the monitoring device 10 and the electronic tag 11 weakens to a certain value or less in communication between the monitoring device 10 and the electronic tag 11.

[0107] Next, the monitoring process of the electronic tag 11 when the bag 19 and the electronic tag 11 are lost will be described below. When the electronic tag 11 detects a communication disconnection (T43), it switches from pairing mode to lost mode (T44). Then, it sets connection conditions (T45), which enable the monitoring device 10 and the smartphone 200 on the print management system 100 to communicate.

[0108] Next, the electronic tag 11 changes the electronic tag ID 188 included in the advertising signal to the lost electronic tag ID and resumes outputting the advertising signal (T46). In this embodiment, the lost electronic tag ID is generated according to a certain rule based on the electronic tag ID 188. For example, the lost electronic tag ID is created by adding "loss," which indicates loss, to the beginning of the electronic tag ID 188, but this is not limited to this. Therefore, the electronic tag 11 that detects the communication disconnection will transmit an advertising signal including the lost electronic tag ID.

[0109] In this way, in this embodiment, different processing can be easily performed in normal mode and lost mode by changing the processing depending on whether the electronic tag 11 being searched for transmits an advertisement including the electronic tag ID 188 or an advertisement including the lost electronic tag ID.

[0110] Furthermore, in this embodiment, when the electronic tag 11 has established a connection with the monitoring device 10, i.e., when it is being monitored by the monitoring device 10, it stops outputting advertising signals and limits the monitored target to one monitoring device 10, thereby simplifying monitoring of the print paper 14 (printed matter), while when it goes into lost mode, it resumes outputting advertising signals and continues to output advertising signals without stopping even if a connection is established with a device during lost mode. In other words, by making it possible for the electronic tag 11 to establish connections with multiple devices (monitoring devices 10 and smartphones 200) in lost mode, it becomes possible for the electronic tag 11 to be searched for from many devices, as will be described later, and the likelihood of finding the electronic tag 11 is increased.

[0111] Next, the monitoring process in the monitoring device 10 and management terminal 5 when the bag 19 and electronic tag 11 are lost will be described with reference to Fig. 9. When the monitoring device 10 detects a communication disconnection (T50), it switches to a loss information recording mode (T51). Then, the monitoring device 10 acquires location information of the monitoring device 10 via the GPS receiver 108 and stores the location information in the storage device 111 (T52). The monitoring device 10 also acquires time information from its built-in clock or GPS information and stores the time information in the storage device 111 (T53).

[0112] Next, the monitoring device 10 reads the printed matter ID 17 of the printing paper 14 (printed matter), location information, time information, etc. from the storage device 111, and then outputs a lost material registration request to the management terminal device 5 (T54). The lost material registration request includes information indicating the lost material registration request, the printed matter ID 17 of the lost printing paper 14 (printed matter), location information at the time of loss, time information at the time of loss, etc. The monitoring device 10 also displays on the user IF 107 that the electronic tag 11 (bag 19) has been lost, and notifies the employee (user) who carries the monitoring device 10 of this (T55). This notification may be made by sound using a buzzer or speaker. The processing of T55 is an example of a loss notification processing. The lost material registration request is an example of a loss command. The processing of T54 is an example of a second transmission processing.

[0113] Furthermore, the management terminal device 5, which has received the lost material registration request, registers the lost material in the cloud server 9 (T56). That is, the cloud server 9 rewrites the discard / loss information 186 of the corresponding record to "lost" based on the printed material ID 17 in the print log information 18 stored in the storage unit 94. Furthermore, the cloud server 9 stores the location and time of loss in the loss time information 189 of the corresponding record based on the printed material ID 17. The processing of T56 is an example of a loss update process.

[0114] Next, the search request process when searching for a lost bag 19 (electronic tag 11) using a smartphone 200 will be described below with reference to Fig. 9. That is, the management terminal device 5 sequentially sends a request to search for a lost electronic tag to the smartphones 200 registered in the printed matter management system 100 (T57). Note that the request to search for a lost electronic tag is an example of a search command, and the process of T57 is an example of a search transmission process.

[0115] Then, the smartphone 200 that has received the lost electronic tag search request determines whether to accept or reject the search (T58). That is, for example, if the smartphone 200 determines from the GPS information (location information) that the smartphone 200 is moving, the smartphone 200 may automatically determine to "accept." Also, if the GPS information (location information) indicates that the smartphone 200 has hardly moved, the smartphone 200 may automatically determine to "reject." Also, the owner of the smartphone 200 may determine to "accept" or "reject" and input it via the user IF 107. In either case, the monitoring application 113 needs to be running on the smartphone 200.

[0116] Next, the smartphone 200 transmits "accept" or "reject" to the management terminal device 5 (T59). Note that "accept" or "reject" is an example of result information, and the processing of T59 is an example of result transmission processing. In this embodiment, "accept" or "reject" is transmitted as result information in the processing of T59, but this is not limited to this. For example, it may be configured to transmit only "accept" as result information. In this case, the management terminal device 5 determines that the smartphone 200 has "rejected" if it does not transmit result information of "accept" within a certain time after transmitting the lost electronic tag search request.

[0117] In this manner, in this embodiment, by having the smartphone 200 confirm whether or not to permit the search for the electronic tag 11, it is possible to avoid the smartphone 200 from being subjected to processing unintended by the user of the smartphone 200, thereby placing a burden on the smartphone 200.

[0118] Next, the management terminal device 5 transmits a location information request to the smartphone 200 that has replied with "accept" (T60). Then, the smartphone 200 that has received the location information request transmits its own GPS information (location information) acquired via the GPS receiver 108 to the management terminal device 5 (T61).

[0119] Next, the management terminal device 5 determines whether the received GPS information (location information) is within the search range, and if the received GPS information (location information) is within the search range, transmits the searched electronic tag information to the smartphone 200 (T62). The smartphone 200 then stores the received searched electronic tag information in the storage device 111. The smartphone 200 also notifies the employee (user) carrying the smartphone 200 via the user IF 107 that it is in search mode for the lost electronic tag 11. The searched electronic tag information includes the printed matter ID 17 of the lost printed sheet 14 (printed matter), location information at the time of loss, the lost electronic tag ID, etc. The printed matter ID 17 may be the printed matter IDs 17 of all printed sheets 14 (printed matters) being transported, or it may be configured to transmit only a portion of the printed matter ID 17, for example, the printed matter ID 17 of the first printed sheet 14 (printed matter) photographed.

[0120] As described above, in this embodiment, the management terminal device 5 determines whether the received GPS information (location information) is within the search range, and if the received GPS information (location information) is within the search range, it transmits the searched electronic tag information to the smartphone 200, thereby improving the efficiency of the search. In other words, a smartphone 200 located far from the monitoring device 10 is unlikely to find a wireless tag, and a search for the electronic tag 11 is likely to be in vain, but this can be avoided in this embodiment. Note that if the management terminal device 5 and each smartphone 200 communicate periodically and the management terminal device 5 has the location information of each smartphone 200 in advance, the lost electronic tag search request of T57 may be transmitted only to smartphones 200 within the search range.

[0121] Next, the search process when searching for a lost bag 19 using the smartphone 200 will be described below with reference to FIG. 10. The employee (user) carrying the smartphone 200 travels to search for the lost bag 19 (electronic tag 11). During this search, the smartphone 200 repeatedly attempts to receive an advertising signal transmitted from the electronic tag 11. This process is an example of the search process. The search process may be executed until a search cancellation notice is received in the process of T81, which will be described later, or may be executed for a certain period of time after a request to search for a lost electronic tag is received in the process of T57.

[0122] In this way, if the search process is configured to be executed immediately after receiving a request to search for a lost electronic tag in the processing of T57, it is expected that the smartphone 200 will be able to quickly find the electronic tag 11. Furthermore, if the search process is configured to be executed until a certain amount of time has passed since receiving a request to search for a lost electronic tag, that is, if the search period is limited, it is possible to avoid placing an excessive burden on the owner of the smartphone 200.

[0123] Then, when the smartphone 200 detects an advertising signal including the lost electronic tag ID transmitted from the lost electronic tag 11 among the received advertising signals (T70), it transmits a connection request to the lost electronic tag 11 (T71). Note that the movement of the employee (user) may be on the way to work, while out of the office, or while on a business trip.

[0124] Then, the electronic tag 11 that has received the connection request establishes a provisional connection with the smartphone 200 (T72) and verifies (T73) the smartphone 200. If the result of the verification shows that there is no problem with the smartphone 200, the electronic tag 11 transmits a request for the printed matter ID 17 to the smartphone 200 (T74).

[0125] Next, the smartphone 200 that has received the request for the printed matter ID 17 transmits the printed matter ID 17 to the electronic tag 11 based on the search electronic tag information stored in the storage device 111 (T75). Next, the electronic tag 11 transmits a connection permission to the smartphone 200 if the received printed matter ID 17 matches the printed matter ID 17 stored in the storage unit (T76).

[0126] Next, the smartphone 200 that has received the connection permission executes a discovery process (T77). In this discovery process, the smartphone 200 acquires its own GPS information (location information) via the GPS receiver 108, acquires the user ID 181 of the employee who owns the smartphone 200, and acquires the discovery time, and stores these in the storage device 111.

[0127] Next, the smartphone 200 transmits a discovery information notification to the management terminal device 5 (T78). This discovery information notification includes the user ID 181 of the finder (employee), GPS information (location information) indicating the discovery location, the discovery time, the printed matter ID 17, etc. The discovery information notification is an example of a discovery command, and the processing of T78 is an example of discovery transmission processing.

[0128] During this discovery process, it may be configured to notify the employee (user) who carries the smartphone 200 via the user IF 107. In this way, by notifying the discovery of the electronic tag 11 even from the smartphone 200 that has been given permission to search for the electronic tag 11, the user of the smartphone 200 can easily notice the discovery, and it is expected that the user of the monitoring device 10 who has lost the electronic tag 11 will quickly find the electronic tag 11 by, for example, contacting the user of the monitoring device 10. The process of notifying the employee (user) who carries the smartphone 200 via the user IF 107 is an example of a third discovery notification process.

[0129] Next, the management terminal device 5, which has received the discovery information notification, transmits the discovery information notification to the monitoring device 10 (T79). The processing of T79 is an example of notification processing. The management terminal device 5 also updates the print log information 18 stored in the storage unit 94 of the cloud server 9 (T80). That is, the cloud server 9 rewrites the discard / loss information 186 of the corresponding record in the print log information 18 stored in the storage unit 94 to "in transport" based on the printed matter ID 17. At this time, it may also be rewritten to "discovered." The cloud server 9 also stores the discovery location and discovery time in the discovery time information 190 of the corresponding record based on the printed matter ID 17.

[0130] Next, the management terminal device 5 transmits a search cancellation notice to all smartphones 200 that accepted the search request, including the smartphone 200 that discovered the electronic tag 11 (T81). The processing of T81 is an example of discovery notification processing. The search cancellation notice may also include the printed matter ID 17 of the search target. The smartphone 200 that receives the search cancellation notice stops searching for the printed matter ID 17 associated with the search cancellation notice and displays this fact via the user IF 107. This causes the owners of the other smartphones 200 to stop searching for the lost electronic tag 11.

[0131] In this manner, in this embodiment, once the electronic tag 11 is found, there is a high possibility that searching for the electronic tag 11 will be futile, so it is preferable to have the other smartphones 200 end the processing based on the search command.

[0132] Furthermore, the monitoring device 10, which has received the discovery information notification, displays on the user IF 107 that the bag 19 (electronic tag 11) has been found, thereby notifying the employee (user) of this (T82). This notification may be made by sound using a buzzer or speaker. At this time, the user IF 107 may also display the discovery location, discovery time, and information about the finder (name, department name, and contact information of the finder) based on the discovery information notification. The processing of T82 is an example of a second discovery notification process.

[0133] In this manner, in this embodiment, after communication between the monitoring device 10 and the electronic tag 11 is interrupted, another employee's smartphone 200 can also attempt to establish a connection with the electronic tag 11 and search for the electronic tag 11, thereby increasing the likelihood of discovering the bag 19 (electronic tag 11). If the bag 19 (electronic tag 11) is discovered, the discovery is notified to the monitoring device 10 along with its location information, making it easier for the user of the monitoring device 10 to discover the bag 19 (electronic tag 11).

[0134] Next, the search process when searching for a lost bag 19 using the monitoring device 10 will be described below with reference to Fig. 10. Note that in this description, the same processes as those in the search process when searching for a lost bag 19 using the smartphone 200 will be assigned the same reference numerals, and the description thereof will be omitted.

[0135] An employee carrying a monitoring device 10 moves around to search for the lost electronic tag 11. During this search, the monitoring device 10 repeatedly attempts to receive advertising signals transmitted from the electronic tag 11. This process is an example of a connection attempt process. When the monitoring device 10 detects, among the received advertising signals, an advertising signal containing the lost electronic tag ID transmitted from the lost electronic tag 11 (T83), the monitoring device 10 transmits a connection request to the lost electronic tag 11 (T84). The connection request of T84 is different from the connection request of T71, and the electronic tag 11 distinguishes between the two.

[0136] Thereafter, when the monitoring device 10 transmits the printed matter ID 17 to the electronic tag 11 in response to a request from the electronic tag 11 (T74) (T85), the electronic tag 11, if it receives and finds that the printed matter ID 17 is correct, cancels lost mode and transitions to normal mode (T86), stops outputting the advertising signal, and also transmits a connection completion notification to the monitoring device 10 (T87).

[0137] In this way, in this embodiment, if the confirmation signal is lost, the device goes into lost mode, and only when a printed matter ID 17 that is the same as the pre-registered printed matter ID 17 is sent will the connection with the sender be re-established.By doing this, even if there is a connection request from another device while the electronic tag 11 is lost, the electronic tag 11 will not unnecessarily establish communication with other devices, thereby ensuring the safety of the electronic tag 11.

[0138] Next, the monitoring device 10 that has received the connection permission executes a discovery process (T88). In this discovery process, the monitoring device 10 acquires its own GPS information (location information) via the GPS receiver 108, acquires the discovery time, and stores them in the storage device 111.

[0139] Next, the monitoring device 10 transmits a discovery information notification to the management terminal 5 (T89). Note that this discovery information notification includes the printed matter ID 17, GPS information (location information) indicating the discovery location, the discovery time, etc. Note that the discovery information notification is an example of a first discovery update command, and the processing of T89 is an example of a first discovery transmission processing.

[0140] Furthermore, the management terminal device 5, which has received the discovery information notification, updates the print log information 18 stored in the storage unit 94 of the cloud server 9 (T90). That is, the cloud server 9 rewrites the discard / loss information 186 of the corresponding record in the print log information 18 stored in the storage unit 94 to "in transport" based on the printed matter ID. At this time, it may also be rewritten to "discovered." Furthermore, the cloud server 9 stores the discovery location and discovery time in the discovery time information 190 of the corresponding record based on the printed matter ID. The processing of T90 is an example of a discovery update process.

[0141] The monitoring device 10 also displays on the user IF 107 that the electronic tag 11 (bag 19) has been found, thereby notifying the employee (user) of this (T91). This process is an example of a first discovery notification process. This notification may be made by sound using a buzzer or speaker. After the electronic tag 11 has been found, the monitoring device 10 periodically checks the connection status with the electronic tag 11 again (T40, T41).

[0142] In this manner, in this embodiment, after communication with the electronic tag 11 is interrupted, repeated attempts are made to immediately re-establish a connection with the electronic tag 11, thereby increasing the likelihood of the electronic tag 11 being discovered. If the connection is successfully re-established, the discovery of the electronic tag 11 is notified and the print log information 18 stored in the cloud server 9 is updated, so that the user of the monitoring device 10 can easily notice the discovery of the electronic tag 11, and third parties other than the user of the monitoring device 10 can also recognize the discovery of the electronic tag 11 via the management terminal device 5.

[0143] Next, silent search, which is another form of processing performed after the management terminal device 5 receives a lost document registration request from the monitoring device 10, will be described below with reference to Fig. 11. In the above-described form, the search using the smartphone 200 is initiated after receiving consent from the smartphone 200, but in silent search, the search is initiated without obtaining consent from the smartphone 200. Note that in this description, processes that are the same as the search process when searching for a lost bag 19 using the smartphone 200 will be assigned the same reference numerals, and their description will be omitted.

[0144] That is, the management terminal device 5, which has received the lost material registration request (T54) and registered the lost material in the cloud server 9 (T56), sequentially transmits a request for silent search for the lost electronic tag to the smartphones 200 registered in the printed matter management system 100 (T92). Note that silent search is a mode in which the smartphone 200 searches for the lost electronic tag 11 in the background. Therefore, the employee (user) who carries the smartphone 200 is not notified that the smartphone 200 is being searched.

[0145] The management terminal device 5 transmits a location information request to the smartphone 200 (T93). Then, upon receiving the location information request, the smartphone 200 transmits its own GPS information (location information) acquired via the GPS receiver 108 to the management terminal device 5 (T94).

[0146] An employee (user) carrying the smartphone 200 moves around during work activities or private activities. When the smartphone 200 detects an advertising signal including the lost electronic tag ID transmitted from the lost electronic tag 11 (T95), the smartphone 200 executes the processes of T77 to T78, the management terminal device 5 executes the processes of T79 to T81, and the monitoring device 10 executes the process of T82.

[0147] According to this embodiment, the smartphone 200 performs a search for the lost bag 19 (electronic tag 11) in the background, so that the employee (user) carrying the smartphone 200 can carry out his / her activities without being aware of the search, thereby reducing the burden on the employee (user).

[0148] As described above in detail, according to this embodiment, the monitoring application 113 establishes a connection with the electronic tag 11, stores the disposal / loss information 186 of the print log information 18, in which a first value indicating that the tag is being transported is set, in the cloud server 9, periodically communicates with the electronic tag 11 while the connection is established, and if the electronic tag 11 is not within a predetermined range, notifies the user of the electronic tag 11 of its loss and rewrites the disposal / loss information 186 stored in the cloud server 9 to a second value indicating that the tag is lost. Therefore, if a user transports the electronic tag 11 together with the printing paper 14 (printed matter), the user of the monitoring device 10 incorporating the monitoring application 113 can easily notice the loss of the electronic tag 11 (printed paper 14 (printed matter)). Furthermore, by having an administrator of the management terminal device 5 or the like refer to the disposal / loss information 186 stored in the cloud server 9, a third party other than the user of the monitoring device 10 can monitor the transport status of the printing paper 14 (printed matter), ensuring safety when the printing paper 14 (printed matter) is transported.

[0149] It should be noted that this embodiment is merely an example and does not limit the present invention in any way. Therefore, the present invention can naturally be improved and modified in various ways without departing from the spirit and scope of the present invention. For example, the PC 2 is not limited to the storage device 24, and may be equipped with any type of large-capacity storage device.

[0150] Furthermore, the communication method between the PC 2 and the printer 4 is not limited to wired communication using a USB cable. For example, wireless communication conforming to the Wi-Fi (registered trademark) standard or wireless communication based on other standards such as Bluetooth (registered trademark) may be used. Furthermore, the printer 4 may have multiple communication functions.

[0151] Furthermore, the two-dimensional barcode 16 and the print ID 17 may be included in the header or footer of the printing paper 14, or may be combined with the image of the page to be printed.

[0152] Furthermore, the user ID 181 and the electronic tag ID 188 of the print log information 18 may be updated when a connection with the electronic tag 11 is established.

[0153] Furthermore, the user ID 181 is input to the electronic tag 11 using the monitoring device 10, but it may be configured so that this is done using the electronic tag application 33 of the PC 2.

[0154] The processes disclosed in the embodiments may be executed by hardware such as a single CPU, multiple CPUs, or ASIC, or a combination thereof. The processes disclosed in the embodiments may be realized in various ways, such as a recording medium on which a program for executing the processes is recorded, or a method.
