Description

[Technical Field]

[0001] The present disclosure relates to a technique for managing a terminal device. [Background technology]

[0002] Patent Document 1 discloses a system in which a server device acquires setting information for an image forming device from a management device and provides the acquired setting information to the image forming device. According to this system, the image forming device can acquire the setting information sent from the server device and configure the image forming device using the acquired information.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-148957 Summary of the Invention [Problem to be solved by the invention]

[0004] In a system configured as described above in which a management device manages terminal devices such as image forming devices using a server device, there may arise a need to temporarily or permanently remove a specific terminal device from the management targets.

[0005] There are various possible specific methods for deleting a specific terminal device from the management target. For example, the administrator may delete the terminal device from the management target by performing an operation on the management device. Another possible method is for the management device to delete the terminal device from the management target in response to a predetermined process indicating deletion from the management target being performed on the terminal device side.

[0006] Regardless of the method used to remove a terminal device from the management list, it is desirable that the administrator be able to properly understand that the terminal device has been removed from the management list on the management device. For example, it would be convenient if the administrator could understand not only the fact that the terminal device has been removed from the management list, but also the cause of the removal (for example, whether the removal was caused by an operation on the management device side or the terminal device side).

[0007] Therefore, one aspect of the present disclosure aims to enable an administrator to properly understand on the management device that a specific terminal device has been deleted from the management target in a system in which a first communication device manages terminal devices via an intermediate device such as a server device. [Means for solving the problem]

[0008] According to one aspect of the present disclosure, a management system includes a first communication device and a second communication device, each of which can access cloud storage, and the second communication device is communicatively connected to at least one of the first terminal devices or is provided in the second terminal device.

[0009] The cloud storage records management target information. The management target information includes information related to each of at least one management target terminal. The management target information is information about a corresponding management target terminal. The at least one management target terminal is one or more of the at least one first terminal device and a second terminal device. The management target information is recorded by a second communication device to which the management target terminal is connected or provided.

[0010] The first communication device executes a display process, a first reception process, a first deletion process, and a second deletion process. The display process includes displaying a first terminal list, in which the at least one managed terminal is listed.

[0011] The first reception process includes receiving a first deletion request, the first deletion request requesting that any one of the at least one managed terminal be deleted from a first terminal list. The first deletion process includes, in response to the first deletion request being accepted by the first acceptance process, identifying in a first manner that the first deletion request has been made to a first terminal to be deleted in the first terminal list. The first terminal to be deleted is a terminal to be managed that is the target of the first deletion request.

[0012] The second deletion process includes, in response to recognizing that a second deletion request has been made by a second communication device based on the contents recorded in the cloud storage, identifying the second deletion request to a second terminal to be deleted in the first terminal list in a second manner. The second deletion request requests that one of the at least one managed terminal be deleted from the managed terminal. The second terminal to be deleted is the managed terminal that is the target of the second deletion request.

[0013] The second communication device executes a second reception process and a deletion response process. The second reception process includes receiving a second deletion request. The deletion response process includes, in response to the second deletion request being received by the second reception process, reflecting in the cloud storage that the second deletion request has been made.

[0014] According to this management system, when a managed terminal is deleted from the first terminal list, the administrator can appropriately grasp the deletion in the first communication device. Specifically, the administrator can easily identify whether the deleted managed terminal was deleted by a first deletion request in the first communication device or a second deletion request in the second communication device, based on whether the deleted managed terminal is identified in the first manner or the second manner (i.e., whether it is identified as a first deleted terminal or a second deleted terminal).

[0015] The first communication device may be configured to retrieve management target information from the cloud storage and / or write task-related data to the cloud storage. The task-related data indicates a task to be executed by the managed terminal. The second communication device may be configured to retrieve management target information from the managed terminal connected to or provided with the second communication device and write the management target information to the cloud storage and / or execute a task based on the task-related data written to the cloud storage.

[0016] In another aspect of the present disclosure, a first communication device or a second communication device constituting the management system may be provided. In yet another aspect of the present disclosure, a management program that is a computer program for causing a computer to function as the first communication device, and a computer program for causing a computer to function as the second communication device may be provided. In yet another aspect of the present disclosure, a management method for managing managed terminals from the first communication device via cloud storage and the second communication device, used in the management system, may be provided, particularly a method for managing managed terminals by referencing cloud storage in the first communication device.

[0018] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. Embodiment] [Overall configuration] The management system 1 according to an exemplary embodiment of the present disclosure is a network system configured to manage terminal devices 3 and 4 located at multiple locations via a cloud server 6 through cooperation between a master 10 and a client 20.

[0019] 1 is configured to be able to communicate with one or more terminal devices 3 installed at a first location via a local area network. The master 10 is further configured to be able to communicate with a cloud server 6 via a wide area network.

[0020] The client 20 is configured to be able to communicate with one or more terminal devices 3 installed at a second location via a local area network. The client 20 is further configured to be able to communicate with the cloud server 6 via a wide area network. The terminal device 4 installed at a third location is configured to be able to communicate with the cloud server 6 via the wide area network.

[0021] The local area network may include, for example, at least one of a wireless LAN and a wired LAN. The wide area network may include, for example, the Internet. A local area network may be established at a third location. In this case, the terminal device 4 may be connected to the wide area network via the local area network within the third location.

[0022] The terminal device 3 does not have the ability to use the cloud services provided by the cloud server 6. In other words, each terminal device 3 does not have the function of communicating with the cloud server 6. Hereinafter, this terminal device 3 will be particularly referred to as a first-type terminal device 3. On the other hand, the terminal device 4 is a terminal device that has the ability to use the cloud services provided by the cloud server 6. In other words, the terminal device 4 has the function of communicating with the cloud server 6. Hereinafter, this terminal device 4 will be particularly referred to as a second-type terminal device 4.

[0023] The first type terminal device 3 installed at the second base is managed by the master 10 via the client 20 and the cloud server 6. The second type terminal device 4 installed at the third base is managed by the master 10 via the cloud server 6 without via the client 20.

[0024] The terminal devices 3 and 4 managed by the master 10 may be, for example, a group of terminal devices managed by an organization such as a company. In this case, each base may be an activity base of the organization. For example, the first base where the master 10 is located may be an office that houses the management department of the organization. The other second and third bases may be branch offices of the organization that are distant from the first base.

[0025] Examples of the terminal devices 3 and 4 include a printer, a scanner, and a digital multifunction peripheral that integrates the functions of these devices. The master 10 and the client 20 are configured, for example, by installing a dedicated computer program on a personal computer.

[0026] [Device configuration] 2A includes a control unit 11, a communication unit 12, a display unit 13, an input unit 14, and a storage unit 15. The control unit 11 includes a CPU 11a and a memory 11b. The CPU 11a as a processor executes processing in accordance with a computer program stored in the storage unit 15. The memory 11b is used as a work memory when the above processing is executed.

[0027] The memory unit 15 includes storage devices such as a solid state drive (SSD) and a hard disk drive (HDD), and stores various computer programs and data. The memory unit 15 stores a main management program 17. The main management program 17 is a computer program that causes the CPU 11a to implement the management functions that should be implemented by the master 10. The processing mainly performed by the control unit 11 described below may be understood to be implemented by processing executed by the CPU 11a in accordance with the computer program.

[0028] The communication unit 12 is connected to a local area network of the base where the master 10 exists, and further connected to a wide area network. The communication unit 12 may be connected to the wide area network via a router (not shown).

[0029] The display unit 13 is configured to display various screens for a user who operates the master 10. An example of the display unit 13 is a liquid crystal display. Examples of the various screens include a device management screen 70 (see FIGS. 7 and 8), a first deletion list screen (see FIG. 10), and a second deletion list screen (not shown), which will be described later. The device management screen 70 is a so-called portal screen in the management function realized by the master 10. A primary administrator, who is a user of the master 10, can basically manage the terminal devices 3 and 4 to be managed by performing various input operations and viewing various information using the device management screen 70 as a starting point. The device management screen 70 can display, for example, log information and status information of the terminal devices 3 and 4 to be managed.

[0030] The input unit 14 includes one or more input devices, such as a keyboard and a pointing device, for inputting operation signals from a user operating the master 10. Specifically, the input unit 14 may include, for example, a mouse. Alternatively, the input unit 14 may include, for example, a touch panel. The touch panel may be disposed so as to overlap the entire or almost entire area of ​​the display unit 13 where an image is displayed. The control unit 11 operates in accordance with the operation signals input through the input unit 14.

[0031] 2B includes a control unit 21, a communication unit 22, a display unit 23, an input unit 24, and a storage unit 25. The control unit 21 includes a CPU 21a and a memory 21b. The CPU 21a as a processor executes processing in accordance with a computer program stored in the storage unit 25.

[0032] The storage unit 25 stores a sub-management program 27. The sub-management program 27 is a computer program that causes the CPU 21a to realize functions related to the management functions of the master 10 that should be realized by the client 20. The processing mainly performed by the control unit 21 described below may be understood to be realized by processing that the CPU 21a executes in accordance with the computer program.

[0033] The communication unit 22 is connected to a local area network of the base where the client 20 exists, and is further connected to a wide area network. The communication unit 22 may be connected to the wide area network via a router (not shown). The display unit 23 includes, for example, a liquid crystal display, and is configured to display various screens for a user operating the client 20. The screens displayed on the display unit 23 include, for example, a client setting screen 110 (see FIG. 9 ), which will be described later. The input unit 24 includes one or more input devices for inputting operation signals from a user operating the client 20. The control unit 21 operates in accordance with the operation signals input through the input unit 24.

[0034] 2C includes a control unit 31, a communication unit 32, a display unit 33, and an input unit 34. When the first type terminal device 3 is, for example, a digital multifunction peripheral, the first type terminal device 3 may further include a printing unit 35 and a reading unit 36. The first type terminal device 3 may include only one of the printing unit 35 and the reading unit 36.

[0035] The control unit 31 includes a CPU 31a and a memory 31b. The memory 31b may include a RAM as well as a nonvolatile memory such as a flash memory, and may store computer programs, setting data, and the like in the nonvolatile memory.

[0036] The CPU 31a as a processor performs overall control of the entire first-class terminal device by executing processes according to the computer programs stored in the memory 31b. The processes mainly performed by the control unit 31 described below may be understood to be realized by the processes executed by the CPU 31a according to the computer programs.

[0037] The communication unit 32 is connected to the local area network of the base where the first type terminal device 3 exists so as to be able to communicate with the master 10 or client 20 present there. The display unit 33 includes, for example, a liquid crystal display, and is configured to display various screens for the user operating the first type terminal device 3. The input unit 34 includes one or more input devices, such as a touch panel on the liquid crystal display, for inputting operation signals from the user.

[0038] The printing unit 35 is configured to print an image on a sheet under the control of the control unit 31. Examples of the printing unit 35 include an inkjet printer and a laser printer. According to this embodiment, status information such as the remaining amount of coloring material and log information such as the number of printed sheets are written from the first type terminal device 3 to the cloud server 6 via the client 20 in a manner described below, and are then provided to the master 10. The reading unit 36 ​​is configured to read an image of a reading target on a printed matter or the like under the control of the control unit 31.

[0039] 3A includes a control unit 41, a communication unit 42, a display unit 43, and an input unit 44. When the second type terminal device 4 is, for example, a digital multifunction peripheral, the second type terminal device 4 may further include a printing unit 45 and a reading unit 46. The second type terminal device 4 may include only one of the printing unit 45 and the reading unit 46.

[0040] The control unit 41 includes a CPU 41a and a memory 41b. The memory 41b may include a nonvolatile memory such as a flash memory, and may store computer programs, setting data, and the like.

[0041] The CPU 41a as a processor performs overall control of the entire device by executing processes in accordance with a computer program stored in the memory 41b. A communication program 47 is stored in the memory 41b. The communication program 47 is a program for using cloud services provided by the cloud server 6. The processes mainly performed by the control unit 41 described below may be understood to be realized by processes executed by the CPU 41a in accordance with the computer program.

[0042] The communication unit 42 is connected to a wide area network so as to be able to communicate with the cloud server 6. If a local area network is established at the third location, the communication unit 42 may be connected to the wide area network via the local area network. The display unit 43 includes, for example, a liquid crystal display. The input unit 44 includes one or more input devices for inputting operation signals from the user.

[0043] The printing unit 45 is configured to print an image on a sheet under the control of the control unit 41. According to this embodiment, status information such as the remaining amount of coloring material and log information such as the number of printed sheets are written from the second type terminal device 4 to the cloud server 6 in a manner described later, and are then provided to the master 10. The reading unit 46 is configured to read an image of a reading target on a printed matter or the like under the control of the control unit 41.

[0044] 3B includes a control unit 61, a communication unit 62, a first storage 63, and a second storage 64. The control unit 61 includes a CPU 61a and a memory 61b.

[0045] The CPU 61a as a processor executes processes in accordance with the computer programs stored in the memory 61b. The processes executed by the CPU 61a include processes for causing the cloud server 6 to function as cloud storage. The processes mainly performed by the control unit 61 described below may be understood to be realized by the processes executed by the CPU 61a in accordance with the computer programs.

[0046] The cloud storage includes a table storage and an object storage. When the control unit 61 executes the above process, the first storage 63 functions as a table storage, and the second storage 64 functions as an object storage.

[0047] The exemplary first storage 63 functions as a NoSQL data store and is configured to store tables each consisting of a set of schema-less entities. Each entity in a table is configured with a set of properties, and each property is configured with a key-value (i.e., value) pair.

[0048] The exemplary second storage 64 functions as an object storage that can read and write any text file and binary file as an object from the outside using the HTTP / HTTPS protocol.

[0049] Microsoft's Azure (registered trademark) is a known cloud service that provides the above-mentioned table storage and object storage. The cloud server 6 can operate in the same manner as such a cloud service.

[0050] The cloud server 6 functions passively with respect to the master 10, the client 20, and the second-type terminal device 4. That is, the cloud server 6 does not actively perform decision processing or the like itself, but does not issue commands, requests, notifications, etc. to the master 10, the client 20, and the second-type terminal device 4. The master 10, the client 20, and the second-type terminal device 4 each write necessary data to the cloud server 6 themselves as needed. Also, the master 10, the client 20, and the second-type terminal device 4 each access the cloud server 6 themselves as needed and read data stored in the cloud server 6.

[0051] The data written by the master 10 to the cloud server 6 may include, for example, data indicating various requests, notifications, etc. (hereinafter abbreviated as "notifications, etc.") targeted at a predetermined one or more of the first-type terminal devices 3 and the second-type terminal devices 4. More specifically, the data indicating notifications, etc. is written to the first storage 63, for example.

[0052] Furthermore, the master 10 writes the above-mentioned text file or binary file, etc., to the second storage 64 as necessary. Specifically, for example, when the master 10 writes data indicating a task instructing firmware update in one or more specific first-type terminal devices 3 and / or second-type terminal devices 4 to the first storage 63, the master 10 writes software (e.g., an update program) required to execute the task (i.e., firmware update) to the second storage 64.

[0053] The data read from the cloud server 6 by the client 20 may include, for example, data indicating the above-mentioned notifications and the like, targeted at a first-type terminal device 3 under the control of the client 20. "Under the control of the client 20" means, in other words, that the device exists within a local area network including the client 20 and is capable of communicating with the client 20. In this embodiment, for example, at the second base, a first-type terminal device 3 connected to the client 20 via a local area network is a first-type terminal device 3 under the control of the client 20. Furthermore, the client 20 may read files written in the second storage 64 as necessary.

[0054] The data read from the cloud server 6 by the second type terminal device 4 may include, for example, data indicating the above-mentioned notifications and the like, which is targeted at the second type terminal device 4. Furthermore, the second type terminal device 4 may read files written in the second storage 64 as necessary.

[0055] Data written to the cloud server 6 by the client 20 may include, for example, status information and log information of the first type terminal device 3 under the control of the client 20. As will be described later, in the first storage 63, a table (for example, a schedule task table described later) corresponding to each first type terminal device 3 under the control of the client 20 is generated individually. This table includes, for example, three entities related to "log," "status," and "registration," as will be described later with reference to FIG. 6. Log information is written to the "log" entity, and status information is written to the "status" entity. Note that various data, described later, is written to the "registration" entity by the master 10.

[0056] Furthermore, if the data written by the master 10 includes data instructing a task (for example, the above-mentioned firmware update) targeted at a first type terminal device 3 under the control of the client 20, the client 20 writes data indicating the execution result of the task to the first storage 63 of the cloud server 6. This data is also written to a table (for example, an instant task table described later) provided individually for each first type terminal device 3 for writing the execution result of the task.

[0057] The data written by the second type terminal device 4 to the cloud server 6 may include, for example, status information and log information of the second type terminal device 4. That is, in the first storage 63, a table corresponding to the second type terminal device 4 is generated for the second type terminal device 4, similar to the above-described first type terminal device 3. Furthermore, if the data written by the master 10 includes data instructing a task targeted at the second type terminal device 4, the second type terminal device 4 writes data indicating the execution result of the task to the first storage 63 of the cloud server 6. Specifically, similar to the above-described case of the first type terminal device 3, the data is written to a table provided to write the execution result of the task of the second type terminal device 4.

[0058] The data read by the master 10 from the cloud server 6 includes, for example, the various data written in the above-mentioned tables. In other words, the master 10 does not directly communicate with the clients 20 or the second-type terminal devices 4. The master 10 writes data to the cloud server 6 or reads data from the cloud server 6 as needed, thereby indirectly sending various notifications to the clients 20 and the second-type terminal devices 4 and acquiring various information from the clients 20 and the second-type terminal devices 4. The clients 20 and the second-type terminal devices 4 also write data to the cloud server 6 or read data from the cloud server 6 as needed, thereby indirectly acquiring various notifications from the master 10 and transmitting various information related to the terminal devices to the master. [Sequence Overview] Next, various examples of management-related operations in the management system 1 will be explained in brief with reference to Fig. 4. First, an example of a preparatory stage for constructing the management system 1 will be explained. Note that an example of operations in this preparatory stage is not shown in Fig. 4.

[0059] In the preparation stage, the main management program 17 is installed in the master 10. As a result, the master 10 executes processing in accordance with the main management program 17. In the following explanation, "the master 10" basically means "the control unit 11 executing the main management program 17."

[0060] A cloud profile is set in the master 10. Setting the cloud profile includes setting cloud parameters. As will be described later, the client 20 and the second-type terminal device 4 perform a polling operation on the cloud server 6 and an update operation of information held in the cloud server 6. The cloud parameters include the period of the polling operation (hereinafter referred to as the "polling period") and the period of the information update operation (hereinafter referred to as the "information update period"). Setting the cloud profile further includes setting a shared access signature (SAS) for using the cloud service.

[0061] The cloud profile is set, for example, in accordance with a setting operation performed by the main administrator via the input unit 14. The SAS is set individually for each of the first storage 63 and the second storage 64, that is, for each of the table storage and the object storage.

[0062] Subsequently, some or all of the configured cloud profile, including the configured cloud parameters, is uploaded from the master 10 to the first storage 63 and written to the first storage 63. Specifically, the cloud parameters are written to the first storage 63 as entities of a table.

[0063] The master 10 further exports at least a portion of the cloud profile as a client profile, i.e., data for reading at the client 20. The client profile may include, for example, the cloud parameters described above.

[0064] The exported client profile is provided to the client 20. The client profile may be provided to the client 20 by any method. For example, the client profile may be provided from the master 10 to the client 20 by email or by using an easily portable storage medium.

[0065] The sub-administrator, who is the user of the client 20, can operate the client 20 to install the sub-management program 27 on the client 20. At this time, the sub-administrator's operation imports the client profile provided by the master 10. As a result, cloud parameters and SAS according to the client profile are set on the client 20. In the following explanation, "the client 20" basically means "the control unit 21 executing the sub-management program 27."

[0066] After the above installation and settings, the client 20 becomes able to use the cloud server 6. That is, the client 20 is configured to be able to communicate information with the master 10 via the cloud server 6. Specifically, the client 20 is configured to be able to execute relay operations between the master 10 and the first type terminal device 3 via the cloud server 6, such as issuing task execution instructions from the master 10 to the first type terminal device 3 and transmitting log information and status information from the first type terminal device 3 to the master 10.

[0067] Meanwhile, an SAS is registered in the second type terminal device 4 by an input operation by a device administrator who is an administrator of the second type terminal device 4. The control unit 41 of the second type terminal device 4 in which the SAS is registered executes processing in accordance with the communication program 47. The control unit 41 executing processing in accordance with the communication program 47 is hereinafter referred to as the "cloud connector." The cloud connector references the cloud parameters written by the master 10 in the first storage 63 of the cloud server 6. The cloud connector acquires these cloud parameters and sets them in its own device.

[0068] In this way, the initial settings of the client 20 and the second type terminal device 4 (cloud connector), including the setting of cloud parameters and SAS, are completed. The operation sequence of the management system 1 after the initial settings are completed will be outlined with reference to FIG.

[0069] Once the above-described initial settings are complete, the client 20 and the cloud connector execute the schedule task periodically in accordance with the set information update period (S01, S02). The schedule task by the cloud connector includes registering the second type terminal device 4 equipped with the cloud connector in the first storage 63 (i.e., setting a schedule task table). For example, when the corresponding second type terminal device 4 is not registered in the first storage 63 (for example, when a corresponding schedule task table does not exist), the cloud connector sets a table corresponding to the second type terminal device 4 in the first storage 63.

[0070] The schedule task by the client 20 includes registering a subordinate type 1 terminal device 3 in the first storage 63. The client 20, for example, searches for a subordinate type 1 terminal device 3. Then, when a type 1 terminal device 3 that is not registered in the first storage 63 is found, the client 20 registers the type 1 terminal device 3 in the first storage 63 (i.e., sets a corresponding table). The client 20 itself also registers the type 1 terminal device 3 that has been found and registered in the first storage 63 as a client-registered device.

[0071] The schedule task also includes periodically updating various pieces of information stored in each table of the first storage 63 in accordance with a set information update cycle. As illustrated in FIG. 6, the schedule task table is made up of a group of entities each including a plurality of properties such as a first key, a second key, a request parameter, a response parameter, a notification source, a status, and a device ID.

[0072] As described above, the schedule task table has three entities related to "log," "status," and "registration" for each of the terminal devices 3 and 4. The information in each entity is updated by the client 20 that manages the corresponding terminal device if the corresponding terminal device is a first-type terminal device 3, or by the cloud connector in the corresponding terminal device if the corresponding terminal device is a second-type terminal device 4 (S01, S02).

[0073] The "Notification Source" property in an entity indicates who updated the entity; when an entity is updated by a client 20, the "Notification Source" property is updated to the value "Client", and when an entity is updated by a cloud connector, the "Notification Source" property is updated to the value "Device".

[0074] The entity related to "log" is a log entity having the value "log" of the first key, and the log information of the terminal device corresponding to the device ID described as the value of the second key is described in the response parameters. The device ID is an ID unique to each of the terminal devices 3 and 4.

[0075] When the corresponding terminal device is, for example, a printer or a digital multifunction peripheral, the log information may include information on the total number of pages printed by the terminal device. The log information may also include, as a print history, information on the user who issued the print command and the number of pages printed for each print job.

[0076] As illustrated in the lower part of Figure 6, the response parameters may include, for example, JSON data. For example, log information may be written in JSON format by associating the object identifier (OID) used in the management information base (MIB) of the corresponding parameter with its value. The descriptions "xxxxx ..." and "yyyyy ..." in the lower part of Figure 6 indicate exemplary abstract representations of object identifiers.

[0077] The initial state of the response parameter before being updated can exist as a request parameter with an initial value associated with the object identifier. In the example at the bottom of Figure 6, the initial value "%MIB(yyyyy ...)%" associated with the OID "yyyyy ..." has been rewritten to the value "4" by the update.

[0078] The entity related to "status" is a status entity having the value "status" of the first key, and status information of one of the terminal devices 3 and 4 corresponding to the device ID described as the value of the second key is described in the response parameters. When the corresponding terminal device is, for example, a printer or a digital multifunction peripheral, the status information may include information on the remaining amount of coloring material in the corresponding terminal device and error information such as paper jams. As with the log entity, the response parameters of the status entity may be described in JSON format.

[0079] The entity related to "registration" is a registration entity having the value "registration" of the first key, and the device information of one of the terminal devices 3, 4 corresponding to the device ID described as the value of the second key is described in the response parameters. In the response parameters, multiple item values ​​that explain the basic configuration of the device are described as device information.

[0080] In the schedule task table, the entity of the schedule task table of the second type terminal device 4 is updated by the corresponding cloud connector (S01). The entity of the schedule task table of the first type terminal device 3 is updated by the client 20 that manages the first type terminal device 3 (S02). Identification information of the client 20 that manages the first type terminal device 3 is written as part of the device information in the registration entity of the first type terminal device 3.

[0081] However, the property "management status" in the registered entity is updated by the master 10. That is, the master 10 writes a display flag in the property "management status".

[0082] In the default state immediately after a terminal device is registered (i.e., immediately after the registration entity of the terminal device is set), the display flag is set to on in advance, for example. Setting the display flag to on means that the terminal device is displayed in the master device list DL (see FIG. 7) of the device management screen 70 in the master 10, which will be described later. In other words, the display flag indicates whether the corresponding terminal device is listed in the master device list DL in the master 10. The display flag may be set to off by default. In this case, the master 10 may set the display flag to on in response to recognizing that the display flag is set to off by the process of S04 described later.

[0083] In the schedule task, the client 20 communicates with each subordinate first-type terminal device 3 within the local area to acquire log information and status information. Then, based on the acquired log information and status information, the client 20 updates (e.g., overwrites) the corresponding log entities and status entities in the first storage 63 (S02).

[0084] In the schedule task, the cloud connector acquires log information and status information of the corresponding type 2 terminal device 4. Then, based on the acquired log information and status information, the cloud connector updates (e.g., overwrites) the corresponding log entity and status entity in the first storage 63 (S01).

[0085] Although not shown in the drawings, the terminal devices 3 and 4 can execute instant tasks, which are non-periodic tasks other than scheduled tasks, based on a request from the master 10. The master 10 can cause the target terminal device to execute the instant task by registering the contents of the instant task and the target terminal device in a predetermined entity (the instant task table described above) in the first storage 63.

[0086] Next, a periodic update process (S03 to S08) that is executed, for example, periodically by the master 10 will be described. The periodic update process may be executed in response to a predetermined trigger, such as an execution instruction operation by an administrator. One of the purposes of the periodic update process is to update the device management screen 70 shown in FIG. 7.

[0087] Therefore, before explaining S03 and subsequent steps, the device management screen 70 of this embodiment will be explained with reference to Figures 7 to 10. Note that the following explanation of the device management screen 70 is based on the premise that the terminal devices 3 and 4 are digital multifunction peripherals with a printer function.

[0088] As shown in FIG. 7, the device management screen 70 includes a first area R1, a second area R2, and a third area R3. In addition, a plurality of tabs are displayed in areas of the device management screen 70 different from the first to third areas R1 to R3. In this embodiment, for example, a first tab 71, a second tab 72, and a third tab 73 are displayed. Any one of the first to third tabs 71 to 73 is alternatively selected via the input unit 14. A screen corresponding to the selected tab is displayed in the first area R1. FIG. 7 shows an example in which the second tab 72 is selected and a screen corresponding to the second tab 72 is displayed. Specifically, when the second tab 72 is selected, a master device list DL is displayed in the first area R1.

[0089] The master device list DL is a list of terminal devices registered as management targets in the master 10. More specifically, the master device list DL is a list of management target terminals that are set to be displayed (i.e., display targets) in the master device list DL among the terminal devices registered as management targets (hereinafter referred to as "management target terminals").

[0090] The device management screen 70 may have a group selection screen (not shown), and the master device list DL may display terminal devices that belong to the group selected on the group selection screen from among the multiple registered terminal devices 3 and 4.

[0091] The master device list DL shown in Fig. 7 is displayed in a table structure having row data for each managed terminal to be displayed. Each row data has information such as the status, model name, toner / ink amount, and node name of the corresponding managed terminal. The status indicates whether the corresponding managed terminal is in a state where it can execute a process based on an external instruction from the master 10 or the like. If the managed terminal is in a state where it can execute a process, the status of the corresponding managed terminal, such as "Ready" or "Toner empty," is displayed. On the other hand, if the managed terminal is in a state where it cannot execute a process based on an external instruction, the status indicates that it is in a state where it cannot execute a process, such as "Connection error."

[0092] The model name indicates the product model name of the corresponding managed terminal. The node name indicates the node name of the corresponding managed terminal. The toner / ink amount indicates the remaining amount of color material used in the printer function of the corresponding managed terminal. If the corresponding managed terminal has the function of an inkjet printer, the color material is ink. If the corresponding managed terminal has the function of a laser printer, the color material is toner. In Figure 6, the remaining amount of color material for each color of CMYK is shown as a bar graph as toner / ink amount.

[0093] The second area R2 displays detailed information about one of the managed terminals displayed in the first area R1, selected via the input unit 14. The second area R2 further includes a graphical user interface for performing predetermined operations on one or more managed terminals designated, for example, by check boxes in the master device list DL. In this embodiment, as illustrated in FIG. 7, for example, a deletion operation object J1 and a task creation object J2 are displayed in the second area R2. The deletion operation object J1 is operated via the input unit 14 to delete one or more managed terminals designated, for example, by check boxes from the master device list DL. The task creation object J2 is operated via the input unit 14 to create an instant task targeting the designated one or more terminals.

[0094] When the delete operation object J1 is operated via the input unit 14, one or more managed terminals designated by the primary administrator using check boxes in the master device list DL are set to be hidden and deleted from the master device list DL. For example, as illustrated in FIG. 7, when the delete operation object J1 is operated with the check boxes of two managed terminals whose node names end with "6" and "7" designated, these two managed terminals are set to be hidden. Then, as illustrated in FIG. 8, these two managed terminals are deleted from the master device list DL. The managed terminals deleted from the master device list DL are placed in a first deletion list DDL1 (see FIG. 10).

[0095] However, even if a managed terminal is deleted from the master device list DL by such a deletion operation in the master 10, the managed terminal is still treated as a managed terminal in practice. That is, a table corresponding to the deleted managed terminal is maintained in the first storage 63. Then, in the first storage 63, deletion target information indicating that the terminal has been deleted in the master 10 is recorded in association with the corresponding table. Specifically, in this embodiment, the value of the "management status" entity in the "registration" entity of the managed terminal that has been made a hidden target, i.e., the display flag, is set to off.

[0096] Due to various factors, a situation may occur in which a certain managed terminal has its display flag set to off in the first storage 63, but is not set as a hidden target in the master 10 and is displayed in the master device list DL. However, even if such a situation occurs, the master 10 acquires information that the display flag is set to off through a periodic update process, and the managed terminal is set as a hidden target.

[0097] The third area R3 displays objects indicating various items related to the management function. In this embodiment, the objects displayed in the third area R3 include a first deletion list object 76 and a second deletion list object 77. These first and second deletion list objects 76, 77 are operated via the input unit 14 to display terminal devices that have been deleted from the master device list DL.

[0098] In this embodiment, there are two cases in which a managed terminal that has been displayed in the master device list DL is deleted from the master device list DL. The first case is a case in which deletion is initiated by the operation of the deletion operation object J1 on the device management screen 70 of the master 10, as described above. The second case is a case in which deletion is initiated by a device deletion process performed by the client 20 or the cloud connector.

[0099] The second case will be described in more detail. As described above, in the client 20, the subordinate first-type terminal devices 3 are registered as client-registered devices. For example, a user of the client 20, such as a sub-administrator, can delete any one or more client-registered devices from the positioning as managed terminals (i.e., remove them from the list of managed devices) by performing a predetermined individual deletion operation via the input unit 24 of the client 20. When the individual deletion operation is performed, the registration of the corresponding terminal device is cancelled in the client 20. Furthermore, the client 20 deletes the registration information of the corresponding terminal device in the first storage 63 (i.e., the table of the corresponding terminal device, etc.). In other words, when the individual deletion operation is performed on the client 20 side, unlike when the deletion operation object J1 is operated on the master 10, the registration information of the corresponding terminal device in the first storage 63 is deleted.

[0100] Furthermore, the client 20 can display a client settings screen 110, as illustrated in FIG. 9 . The sub-administrator can configure various settings for the client 20 through the client settings screen 110. The various settings that can be configured through the client settings screen 110 include enabling or disabling the cloud connection function. That is, the sub-administrator can enable or disable the function of connecting from the client 20 to the cloud server 6. In this embodiment, for example, the client settings screen 110 displays a checkbox 111 for enabling or disabling the cloud connection function. When the checkbox 111 is checked by the sub-administrator, the cloud connection function is enabled. Various functions performed by the client 20, such as the schedule task described above, in the overall management function are realized by enabling the cloud connection function on the client 20. On the other hand, when the cloud connection function is disabled, for example, by unchecking the checkbox 111, the client 20 deletes the registration information of the subordinate terminal devices from the first storage 63. Then, various management-related processes using communication with the cloud server 6, such as the schedule task, are stopped.

[0101] In the cloud connector, the cloud connection function can also be enabled or disabled by a predetermined operation via the input unit 44 of the second-type terminal device 4 equipped with the cloud connector. When the cloud connection function is enabled, the cloud connector performs various functions such as the schedule task described above. On the other hand, when the cloud connection function is disabled, the cloud connector deletes the registration information of the second-type terminal device 4 equipped with the cloud connector from the first storage 63. Then, various management-related processes using communication with the cloud server 6, such as schedule tasks, are stopped.

[0102] In this way, when a managed device is removed from the list of managed devices by the client 20 or the cloud connector, the registration information of the managed device in the first storage 63 is deleted.

[0103] The master 10 is made aware by its periodic update process that the registration information of the managed device has been deleted from the first storage 63. When the master 10 is made aware that the registration information of any of the managed terminals listed in the master device list DL has been deleted from the first storage 63, the master 10 deletes the managed terminal from the master device list DL and places it in a second deletion list (not shown). The second deletion list has, for example, the same or similar format as the first deletion list DDL1.

[0104] The primary administrator can selectively display the first deletion list DDL1 and the second deletion list on the display unit 13 of the master device 10. For example, the master device 10 may display a first deletion list screen 80, as illustrated in FIG. 10, on the display unit 13 in response to an operation of the first deletion list object 76 on the device management screen 70 via the input unit 14. The first deletion list DDL1 is displayed on the first deletion list screen 80. The first deletion list screen 80 also displays a restore operation object J3. The primary administrator can specify a terminal device in the first deletion list DDL1, for example, using a checkbox, and then operate the restore operation object J3 to re-list the specified terminal device in the master device list DL. In this case, the terminal device is deleted from the first deletion list DDL1. Furthermore, a corresponding display flag in the first storage 63 is set to ON.

[0105] Similarly, the master 10 may display a second deletion list screen (not shown) on the display unit 13 in response to an operation of the second deletion list object 77 on the device management screen 70 via the input unit 14. The second deletion list screen displays the second deletion list. The second deletion list screen may have a form similar to that of the first deletion list screen 80 of FIG. 10, for example. In other words, a terminal device listed in the second deletion list may also be listed again in the master device list DL by operating the restore operation object J3.

[0106] The first deletion list DDL1 and the second deletion list DDL1 may be displayed in response to an operation different from the above. For example, an image for selecting a process may be popped up in response to an operation of the first deletion list object 76 via the input unit 14. Then, the first deletion list DDL1 may be displayed in response to an object included in the image for displaying the first deletion list DDL1 being selected. Also, for example, an object other than the first deletion list object 76 may be displayed on the screen, and the first deletion list DDL1 may be displayed in response to an operation of that object. The same applies to specific operations for displaying the second deletion list.

[0107] Returning to Figure 4, the periodic update process by the master 10 will be explained. When the time to execute the periodic update process arrives, the master 10 requests device data from the first storage 63 (S03) and acquires the device data from the first storage 63 (S04). The device data here specifically means the data in the tables of each managed terminal. That is, in S04, data of each entity of "log," "status," and "registration" is acquired for each managed terminal.

[0108] The master 10, having acquired the device data, checks the display flag of each managed terminal. The master 10 further checks the registration status in the first storage 63 based on the acquired device data (S06). In other words, it identifies the managed terminals currently registered in the first storage 63 (i.e., in which a table including a "Registration" entity is registered).

[0109] The master 10 then updates the master device list DL based on the acquired device data (S07). Specifically, if the master device list DL lists a managed terminal whose display flag is set to off based on the result of the display flag confirmation process in S05, the master 10 deletes the managed terminal from the master device list DL and places it in a first deletion list DDL1. Furthermore, if the master device list DL lists a terminal device that is not registered in the first storage 63 (i.e., a terminal device that has been deleted from management by the client 20 or the cloud connector) based on the result of the registration status confirmation in S06, the master 10 deletes the managed terminal from the master device list DL and places it in a second deletion list. Then, if the device management screen 70 is currently displayed on the display unit 13, the master 10 displays the master device list DL updated in S07 on the device management screen 70 (S08).

[0110] Next, the device deletion process by the master 10 (corresponding to the first case described above) will be described. The device deletion process by the master 10 is executed in response to an operation of the deletion operation object J1 on the device management screen 70. When the deletion operation object J1 is operated, the master 10 accepts the operation (S11). When the master 10 accepts the operation of the deletion operation object J1, it sets to OFF the display flag of one or more management terminal devices (hereinafter referred to as "devices to be deleted") designated by check boxes or the like among the managed terminals listed in the master device list DL (S12). That is, the master 10 accesses the first storage 63 and sets to OFF the display flag of the "registration" entity of the device to be deleted.

[0111] Furthermore, the master 10 moves the devices to be deleted from the master device list DL to the first deletion list DDL1 (S13). If the device management screen 70 is currently displayed on the display unit 13, the master device list DL updated in S13 is displayed on the device management screen 70 (S14).

[0112] Next, the device deletion process by the client 20 (corresponding to the second case described above) will be described with reference to Fig. 5. When a registration deletion operation is performed by a sub-administrator or the like, the client 20 accepts the registration deletion operation (S21). The registration deletion operation includes the individual deletion operation described above and an operation of disabling the cloud connection function via the client setting screen 110 (see Fig. 9) described above.

[0113] When the client 20 receives the registration deletion operation, it deletes the registration information of the managed terminal specified by the registration deletion operation from the first storage 63 (S22). For example, if an individual deletion operation is performed, the registration information is deleted individually for each specified managed terminal. If the cloud connection function is disabled, the registration information of the managed terminals under the client 20 is deleted all at once. As a result, if a periodic update process is performed in the master 10 after execution of S22, the managed terminal deleted in S22 will be deleted from the master device list DL and placed in the second deletion list.

[0114] Next, the device deletion process by the cloud connector (corresponding to the second case described above) will be described. When a sub-administrator or the like performs an operation to disable the cloud connection function on a type 2 terminal device equipped with a cloud connector, the cloud connector accepts the operation (S31). Then, the cloud connector deletes the registration information of the type 2 terminal device 4 equipped with the cloud connector from the first storage 63 (S32). As a result, when a periodic update process is performed in the master 10 after execution of S32, the managed terminal deleted in S32 will be deleted from the master device list DL and placed in the second deletion list.

[0115] Next, a description will be given of the deletion list display process by the master 10. When a deletion list display operation is performed on the device management screen 70 by the primary administrator or the like, the master 10 accepts the deletion list display operation (S41). The deletion list display operation is an operation requesting the display of the first deletion list DDL1 or the second deletion list, and in this embodiment corresponds to an operation on the first deletion list object 76 or the second deletion list object 77.

[0116] When the master 10 receives the deletion list display operation, it displays a deletion list screen including one of the first deletion list DDL1 and the second deletion list specified by the deletion list display operation on the display unit 13 (S42). For example, if the deletion list operation is an operation on the first deletion list object 76, it displays the first deletion list screen 80 including the first deletion list DDL1.

[0117] Next, a device re-display process by the master 10 will be described. When the first deletion list screen (FIG. 10) or the second deletion list screen is displayed on the display unit 13 of the master 10, and a re-display operation is performed by the main administrator or the like via the input unit 14, the master accepts the re-display operation (S51). The re-display operation is an operation requesting that the deleted managed terminal be displayed again in the master device list DL. Specifically, the re-display operation corresponds to operating the restore operation object J3 described above via the input unit 13.

[0118] The master 10, which has accepted the redisplay operation, sets the display flag of the managed device to be redisplayed in the first storage 63 to ON (S52). Furthermore, the master 10 moves the device to be redisplayed that is arranged on the first deletion list screen or the second deletion list screen to the master device list DL (S53). Then, if the device management screen 70 is currently displayed on the display unit 13, the master device list DL updated in S53 is displayed on the device management screen 70 (S54).

[0119] [Effects of the embodiment] According to the present embodiment described above, when a managed terminal is deleted from the master device list DL, the main administrator can appropriately grasp the deletion in the master 10. Specifically, based on whether the deleted managed terminal is placed in the first deletion list or the second deletion list, the main administrator can easily identify whether the deletion was due to an operation on the master 10 side or an operation on either the client 20 or the cloud connector.

[0120] More specifically, the main administrator can display the first deletion list and the second deletion list on the master 10. Then, based on the terminal devices listed in the displayed first deletion list and second deletion list, the main administrator can easily identify the deletion cause of the deleted managed terminal.

[0121] Furthermore, when a registration deletion operation of a managed device is performed in the client 20 or the cloud connector, the table of the corresponding terminal device is deleted from the first storage 63. Therefore, when a managed terminal is deleted from the management targets by the client 20 or the cloud connector, the master 10 can easily know that the management target terminal has been deleted by appropriately referring to the first storage 63.

[0124] 2. Other Embodiments Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be implemented in various modified forms.

[0125] For example, in the above embodiment, as an example of the first aspect of the present disclosure, a managed terminal deleted from the master device list DL in the master 10 is placed in a first deletion list. Furthermore, as an example of the second aspect of the present disclosure, a managed terminal deleted in the client 20 or the cloud connector (hereinafter abbreviated as "cloud side") is placed in a second deletion list. However, the first and second aspects of the present disclosure are not limited to the above-described exemplary aspects. That is, when a managed terminal is deleted from the master device list DL in the master 10, the managed terminal may be identified in any manner that allows the main administrator to recognize that the managed terminal has been deleted by an operation on the master 10. Furthermore, when a managed terminal is deleted on the cloud side, the managed terminal may be identified in any manner that allows the main administrator to recognize that the managed terminal has been deleted by an operation on the cloud side.

[0126] For example, in the master device list DL of the device management screen 70, deleted managed terminals may be displayed in a different manner from other undeleted managed terminals and in a different manner depending on whether they were deleted on the master 10 or the cloud side. Specifically, managed terminals deleted on the master 10 may be displayed in a grayed-out manner, and managed terminals deleted on the cloud side may be displayed in a different manner from the grayed-out manner (for example, by superimposing a gray background color). Also, for example, in the master device list DL, managed terminals deleted on the master 10 and managed terminals deleted on the cloud side may be displayed with different images added to them.

[0127] Furthermore, for example, a single deletion object may be displayed on the device management screen 70 instead of the first deletion list object 76 and the second deletion list object 77. When the object is operated, a deletion list screen similar to the first deletion list screen 80 shown in Fig. 10 may be displayed. On the deletion list screen, the managed terminals deleted on the master 10 and the managed terminals deleted on the cloud side may be displayed together in different formats.

[0128] Furthermore, the method for deleting a managed terminal from the master device list DL in the master 10 is not limited to operating the deletion operation object J1. Furthermore, the method for deleting a managed terminal from management in the client 20 or cloud connector is not limited to the above-mentioned various operations, including the operation via the client setting screen 110.

[0129] Furthermore, when an operation to delete a managed terminal from the management targets is performed in the client 20 or the cloud connector, the table of the corresponding managed terminal in the first storage 63 may be processed in any manner. For example, the entire table may be deleted, or a specific portion of the table may be deleted. In this case, the master 10 may determine whether the managed terminal has been deleted by the client 20 or the cloud connector depending on whether the specific portion has been deleted.

[0130] The first storage 63 is not limited to a NoSQL data store, but may be an SQL database such as a relational database. At least one of the first and second bases may be provided with a second type terminal device 4. At the third base, a network system similar to that at the second base, i.e., a client 20 and a first type terminal device 3, may be provided. In the management system 1, there may be multiple network systems similar to that at the second base.

[0131] In the above embodiments, multiple functions of one component may be realized by multiple components, or one function of one component may be realized by multiple components. Furthermore, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Furthermore, part of the configuration of the above embodiments may be omitted. Furthermore, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments. [Explanation of symbols]
