In this case, the transmitting unit 48 transmits a message serial number that is a number uniquely determined for each certificate data together with the certificate data.

  The log generation unit 51 of the delivery server 24 generates a transmission log each time the transmission unit 48 transmits certificate data. The log storage unit 52 of the delivery server 24 stores the transmission log generated by the log generation unit 51.

  For example, as shown in FIG. 4, the log storage unit 52 of the delivery server 24 stores the transmission log as a database. As an example, the transmission log includes a message serial number of the transmitted certificate data, a transmission date and time, and an identification number of the terminal device 21 that is the transmission destination of the certificate data.

  The receiving unit 49 of the terminal device 21 receives the message serial number and the certificate data from the delivery server 24. The print control unit 50 of the terminal device 21 causes the multifunction device 31 to print the certificate data received by the receiving unit 49. Thereby, the terminal device 21 can provide a certificate to the user.

  The log generation unit 53 of the terminal device 21 generates a print log each time the print control unit 50 controls printing of certificate data. Note that the log generation unit 53 also generates a print log even when printing of a certificate is not completed due to interruption of printing processing or the like.

  The log transmission unit 55 of the terminal device 21 transmits the print log generated by the log generation unit 53 to the information management server 25 every time the print control unit 50 performs print control of certificate data.

  The log reception unit 56 of the information management server 25 receives the print log transmitted by the log transmission unit 55 of the terminal device 21. The log storage unit 57 of the information management server 25 stores the print log received by the log reception unit 56.

  For example, as shown in FIG. 5, the log storage unit 57 of the information management server 25 stores the print log as a database. The print log, for example, identifies the message serial number of the printed certificate data, the number of copies, the fee charged, the date and time of printing, and whether or not printing has been completed or printing has not been completed. Including.

  The confirmation unit 59 of the terminal device 21 transmits a confirmation request to the monitoring server 26 after the terminal device 21 is activated (including restart). For example, the terminal device 21 is activated at a preset activation time, and transmits a confirmation request after activation. Further, the terminal device 21 may restart in response to receiving a restart command from the monitoring server 26 and transmit a confirmation request after the restart.

  The confirmation receiving unit 60 of the monitoring server 26 receives the confirmation request transmitted by the terminal device 21. The setting storage unit 61 of the monitoring server 26 stores various types of information regarding each of the plurality of terminal devices 21.

  For example, as illustrated in FIG. 6, the setting storage unit 61 of the monitoring server 26 includes an identification number, installation location information, a group such as a store chain in which the terminal device 21 is installed, for each of the plurality of terminal devices 21. Setting information to be transmitted to the terminal device 21 is stored. The setting information includes an interval (first communication interval) at which the terminal device 21 transmits state information to the monitoring server 26, the presence / absence of an update program, and the like.

  The setting storage unit 61 of the monitoring server 26 may store a common first communication interval for all terminal devices 21. The setting storage unit 61 may store a different first communication interval for each terminal device 21. The setting storage unit 61 may store a common first communication interval for each group.

  The setting transmission unit 62 of the monitoring server 26 transmits a response signal to the terminal device 21 in response to the confirmation reception unit 60 receiving the confirmation request. In this case, the setting transmission unit 62 includes the setting information stored in the setting storage unit 61 in association with the terminal device 21 that has transmitted the confirmation request, in the response signal.

  The setting acquisition unit 63 of the terminal device 21 acquires setting information included in the response signal returned in response to the transmission of the confirmation request. The setting acquisition unit 63 gives the first communication interval included in the setting information to the determination unit 66 and the state transmission unit 67. If the setting information includes information indicating that there is an update program, the setting acquisition unit 63 downloads the update program from, for example, a predetermined server and updates the program.

  The identification information storage unit 64 of the terminal device 21 stores identification information assigned to the terminal device 21. The random number generation unit 65 of the terminal device 21 generates a random number using the identification information stored in the identification information storage unit 64 as a seed. The random number generator 65 may generate a random number using the date and time as a seed together with the identification information.

  Based on the random number generated by the random number generation unit 65, the determination unit 66 of the terminal device 21 determines the first time (start time) at which the state information representing the state of the terminal device 21 is transmitted. For example, the determination unit 66 determines the start time based on the random number generated by the random number generation unit 65 within a time range equal to or shorter than the first communication interval (for example, 30 minutes) from the current time.

  In addition, the status transmission unit 67 of the terminal device 21 monitors the status information for each first communication interval (for example, every 30 minutes) acquired by the setting acquisition unit 63 from the start time determined by the determination unit 66. 26.

  The status receiving unit 68 of the monitoring server 26 receives the status information transmitted from the terminal device 21. The state storage unit 69 of the monitoring server 26 stores the state information received by the state reception unit 68.

  For example, as shown in FIG. 7, the state storage unit 69 of the monitoring server 26 stores the state information in a database. The state information includes, as an example, the identification number of the terminal device 21 that transmitted the state information, the date and time when the state information was transmitted, and the state. The status includes, for example, whether or not it is normal and the type of error.

  The command acquisition unit 81 of the monitoring server 26 acquires a command to be given to the terminal device 21 from the manager terminal 27 together with the identification number of the terminal device 21. Here, the command is, for example, a command for restarting the terminal device 21.

  The registration unit 82 of the monitoring server 26 performs reservation registration to transmit the command acquired by the command acquisition unit 81 to the corresponding terminal device 21. The response unit 83 of the monitoring server 26 transmits a response signal to the corresponding terminal device 21 in response to the state receiving unit 68 receiving the state information from the terminal device 21. In this case, the response unit 83 includes the registered command in the response signal when it is reserved and registered to transmit the command to the corresponding terminal device 21.

  The response reception unit 84 of the terminal device 21 receives the response signal transmitted from the monitoring server 26 according to the state information transmitted by the state transmission unit 67. When a command is included in the response signal received by the response receiver 84, the command execution unit 88 of the terminal device 21 executes processing according to the included command. For example, when the response signal includes a restart command, the command execution unit 88 restarts the terminal device 21.

  FIG. 8 is a diagram illustrating a sequence at the time of printing a certificate. In the document printing system 10, processing is executed in the sequence shown in FIG. 8 when printing a certificate.

  First, in step S101, the terminal device 21 receives input of user information and a certificate type by the user. In this case, the terminal device 21 charges a fee as necessary.

  Subsequently, in step S102, the terminal device 21 transmits a certificate acquisition request to the delivery server 24 together with the user information and the certificate type. The delivery server 24 determines the local public entity server 22 that issues a corresponding certificate based on the user information and certificate information received from the terminal device 21. In step S103, the delivery server 24 transmits a certificate acquisition request together with the user information and the certificate type to the determined local public entity server 22.

  Upon receiving the certificate acquisition request from the delivery server 24, the local public entity server 22 creates certificate data in a format corresponding to the certificate type based on information about the user indicated in the user information. In step S104, the local public entity server 22 transmits the created certificate data to the delivery server 24.

  Subsequently, in step S <b> 105, the delivery server 24 generates a message sequence number for the certificate data received from the local public entity server 22, and transmits the certificate data and the message sequence number to the terminal device 21. In step S <b> 106, the delivery server 24 stores a transmission log of the certificate data transmitted to the terminal device 21.

  Subsequently, in step S107, the terminal device 21 prints the certificate data received from the delivery server 24 on a sheet. Subsequently, in step S108, the terminal device 21 stores a print log of the printed certificate data. Note that the terminal device 21 also generates a print log even when printing of a certificate is not completed due to interruption of the printing process or the like.

  Subsequently, in step S <b> 109, the terminal device 21 transmits a print log to the information management server 25. Subsequently, in step S <b> 110, the information management server 25 stores the print log received from the terminal device 21.

  Through the above processing, the document printing system 10 can provide a user with a certificate such as a resident's card issued by a local public entity from a terminal device 21 installed in a store or public facility. .

  FIG. 9 is a diagram illustrating a sequence for determining the start time of transmission of state information and a sequence for monitoring the state of the terminal device 21. The document printing system 10 executes the status information transmission start time and the status monitoring process of each of the plurality of terminal devices 21 in the sequence shown in FIG.

  First, in step S201, the terminal device 21 is activated. The terminal device 21 may be started by being turned on at a preset time, or may be restarted in response to receiving a restart command.

  Subsequently, in step S <b> 202, the terminal device 21 transmits a confirmation request to the monitoring server 26 after being activated. Subsequently, in step S203, the monitoring server 26 returns a response signal in response to receiving the confirmation request. In this case, the monitoring server 26 includes the first communication interval as setting information in the response signal.

  Subsequently, in step S204, when receiving the response signal returned in response to the transmission of the confirmation request, the terminal device 21 generates a random number using the identification information as a seed. In this case, the terminal device 21 may generate a random number using the date and time as a seed together with the identification information.

  Subsequently, in step S205, the terminal device 21 determines a start time for transmitting the first state information based on the generated random number. Specifically, the terminal device 21 determines the start time based on the generated random number within a time range equal to or shorter than the first communication interval (for example, 30 minutes) from the current time. Thereby, the terminal device 21 can set the transmission start time of the state information to a random time between the current time and the first communication interval.

  Subsequently, in step S206, the terminal device 21 waits for processing until the start time. Subsequently, in step S207, the terminal device 21 transmits initial state information to the monitoring server 26 when the start time is reached. The state information includes information indicating whether or not the terminal device 21 is normal, or information indicating the type of abnormality when an abnormality has occurred. Thereafter, as shown in steps S209 and S213, the terminal device 21 transmits state information to the monitoring server 26 at each first communication interval.

  On the other hand, as shown in steps S <b> 208, S <b> 210, and S <b> 214, the monitoring server 26 returns a response signal in response to receiving the status information from the terminal device 21. Thereby, the terminal device 21 can know that the state information has been normally transmitted to the monitoring server 26.

  Further, as shown in step S211, the monitoring server 26 can accept a command to be given to any one of the terminal devices 21 from the manager terminal 27 or another device. For example, the monitoring server 26 can accept a restart command for restarting the terminal device 21, a shutdown command for shutting down the terminal device 21, and the like.

  When receiving the command, the monitoring server 26 registers and registers transmission of the received command as shown in step S212. When the status information is received from the corresponding terminal device 21 after the reservation registration, as shown in step S214, the monitoring server 26 includes the reservation registered command in the response signal for the status information. And as shown to step S215, the terminal device 21 which received the response signal containing a command performs the process according to the contained command. Thus, the monitoring server 26 can cause the designated terminal device 21 to execute arbitrary processing.

  FIG. 10 is a diagram illustrating the transmission timing of the state information of each of the plurality of terminal devices 21. Each of the plurality of terminal devices 21 determines the start time of transmission of state information based on a random number using unique terminal information as a seed.

  As a result, as shown in FIG. 10, each of the plurality of terminal devices 21 starts transmitting the status information from a different start time, and thereafter, each of the terminal devices 21 periodically (every first communication interval). Can be accessed. As a result, each of the plurality of terminal devices 21 can access the monitoring server 26 at different times. Accordingly, in the monitoring server 26, accesses from the plurality of terminal devices 21 are distributed, and the processing load is reduced.

  FIG. 11 is a diagram illustrating the timing of restarting the terminal device 21. For example, the plurality of terminal devices 21 may continue to be activated for 24 hours and may be restarted when a restart command is received from the monitoring server 26. In such a case, the monitoring server 26 gives a restart command to each of the plurality of terminal devices 21 every second communication interval longer than the first communication interval (for example, 30 minutes). For example, the monitoring server 26 periodically gives a restart command to each of the plurality of terminal devices 21 every day (24 hours). Thereby, the monitoring server 26 can periodically reset the plurality of terminal devices 21 and can check the setting information periodically.

  Here, as shown in FIG. 11, the monitoring server 26 distributes the timing of giving the restart command to each of the plurality of terminal devices 21 within the range of the second communication interval. For example, the monitoring server 26 gives a restart command so that each of the plurality of terminal devices 21 is restarted at timings distributed over one day (24 hours). Thereby, the monitoring server 26 can reduce the communication load because the responses to the confirmation request after the restart are distributed.

  As described above, according to the document printing system 10 according to the present embodiment, the transmission start timing of the status information from the plurality of terminal devices 21 is randomly shifted, so the processing of the monitoring server 26 is distributed. Thus, according to the document printing system 10, it is possible to reduce the processing load with a simple configuration without providing a load balancer or the like.
