[0047] The system administrator's account has the authority to view, read, write, and delete all of the shared folders 131 and their subfolders and data, regardless of whether the expiration date specified by the expiration date information has passed.

[0048] All or part of the various data stored in the storage device 40 described above may be stored in the storage device 23 , and the control unit 21 may read the data from the storage device 23 .

[0049] <Class registration function on information processing device> A method for an administrator to register a new lesson in the lesson DB 42 using his / her own terminal device 10 will be described below. In addition, a flow of processes that the program 23a causes the control unit 21 to execute will be described with reference to Fig. 6(a).

[0050] An administrator uses an input device of the terminal device 10 to instruct execution of an application program. When the administrator instructs execution of the application program, the terminal device 10 starts the application program and accesses the information processing device 20 via the network 9 according to the control contents of the application program. The control unit 80 of the information processing device 20 transmits a login screen to the terminal device 10, and the terminal device 10 displays the login screen received from the information processing device 20. When the administrator inputs his / her user ID and password on the login screen and commands login, the terminal device 10 transmits the ID and password to the information processing device 20. The control unit 21 of the information processing device 20 performs a verification process to verify the ID and password received from the terminal device 10 with verification data. If the control unit 21 of the information processing device 20 authenticates the authenticity of the user ID and password by the verification process, it permits login of the account corresponding to the user ID. Thereafter, the control unit 21 temporarily stores the logged-in user ID until logout.

[0051] After permitting login to the administrator's account, the control unit 21 of the information processing device 20 transmits an administration screen to the terminal device 10, and the terminal device 10 displays the administration screen. The administrator inputs a command on the administration screen to transition to a class registration screen. The terminal device 10 accepts the command and transfers the input command to the control unit 21 of the information processing device 20, which then accepts the command. The control unit 21 then transmits registration screen display data to the terminal device 10 for displaying the registration screen.

[0052] When the terminal device 10 receives the registration screen display data from the control unit 21, the terminal device 10 displays the registration screen according to the registration screen display data. Fig. 5 shows an example of the registration screen. As shown in Fig. 5, objects 81 to 89 are arranged on the registration screen. The objects 81 to 89 are elements that constitute a GUI (Graphical User Interface) that reflects the contents that reflect the administrator's operations.

[0053] The object 81 is a drop-down list or list box that lists at least one item of subject information as a choice. When the administrator operates the terminal device 10, the object 81 is activated, at least one item of subject information is displayed in a list in the object 81, and one of the choices is selected from the list.

[0054] Object 82 is a drop-down list or list box that lists multiple types of lesson formats, namely, the type "normal", the type "joint", and the type "selection", as options. When the administrator operates the terminal device 10, object 82 is activated, multiple types of lesson formats are displayed in a list in object 82, and one option is selected from the list. When the type "normal" is selected in object 82, one group consisting of objects 86 and 87 is placed on the registration screen. When the type "joint" is selected in object 82, multiple groups consisting of objects 86 and 87 are placed on the registration screen. When the type "selection" is selected in object 82, the display of objects 86 and 87 disappears.

[0055] The object 83 is a text box for inputting the name of the lesson. When the administrator operates the terminal device 10, the object 83 is activated and text representing the name of the lesson is input into the object 83.

[0056] The object 84 is a text box for inputting a description of the lesson, such as the objective or content of the lesson, etc. When the administrator operates the terminal device 10, the object 84 is activated and text representing the description of the lesson is input into the object 84.

[0057] Object 85 is a drop-down list or list box that lists multiple candidates for the year in which the class will be taught as options. When the administrator activates object 85 by operating the input device of terminal device 10, the multiple candidates are displayed in a list in object 85, and one of the options can be selected from the list.

[0058] The object 86 is a drop-down list or list box that lists multiple school years as options. The administrator operates the terminal device 10 to activate the object 86, and multiple school years are displayed in a list in the object 86, and any one option from the list is selected.

[0059] Object 87 is a drop-down list or list box that lists as options at least one pair that belongs to the grade selected in object 86. When the administrator operates the terminal device 10, object 87 is activated, at least one pair is displayed in a list in object 87, and any one option from the list is selected.

[0060] The object 88 is a command button for canceling the selection or input from the objects 81 to 86 and returning to the management screen from the registration screen.

[0061] The object 89 is a command button for confirming the selection or input by the objects 81 to 86. In addition to the objects 81 to 89, objects such as a text box for inputting an expiration date, a drop-down list, a list box, or a date input form may be arranged on the registration screen.

[0062] The administrator operates the terminal device 10 to select one option from the list for each of the objects 81, 82, 85, 86, and 87, inputs the class name in text in the object 83, and further inputs an explanation of the class in text in the object 84, and then selects and confirms the object 89. Then, the terminal device 10 acquires the option in the object 81 as subject information, acquires the option in the object 82 as type information, acquires the input text in the object 82 as class name information, acquires the input text in the object 83 as explanation information, acquires the option in the object 85 as year information, and acquires the combination of the options in the objects 86 and 87 as affiliation information (target student information). The terminal device 10 transmits the information to the information processing device 20, and the control unit 21 of the information processing device 20 receives the information (step S1). The control unit 21 of the information processing device 20 assigns a new class ID, associates the new class ID with the received subject information, type information, class name information, explanatory information, year information, and affiliation information (target student information), and records the combination of the class ID, subject information, type information, class name information, explanatory information, year information, and affiliation information (target student information) in the storage device 40 so as to add the combination to the class DB 42 (step S1). Note that, if the administrator selects the type "select" in the object 82, the terminal device 10 does not transmit the affiliation information (target student information), and the control unit 21 does not record the affiliation information (target student information).

[0063] Next, the control unit 21 creates a shared folder 131 under the group folder 130, and acquires a path for the shared folder 131 (step S2). The control unit 21 associates the path information describing the acquired path with a new class ID, and records the path information in the storage device 40 so that the path information is added to the class DB 42 (step S2). Furthermore, the control unit 21 acquires the last day of the year as the expiration date based on the year information. The control unit 21 associates the expiration date information describing the acquired expiration date with the new class ID, and records the expiration date information in the storage device 40 so that the expiration date information is added to the class DB 42 (step S2).

[0064] Next, the control unit 21 extracts the user IDs and name information of accounts with the authority type "teacher" from the account DB 45, and generates a list in which the user IDs and name information are listed as options for in-charge candidates (step S3). Next, the control unit 21 transmits first association screen display data for displaying a first association screen including the list to the terminal device 10 (step S4). The first association screen display data includes command data for displaying the user IDs and name information of accounts with the authority type "teacher" on the first association screen as options for in-charge candidates.

[0065] When the terminal device 10 receives the first association screen display data from the control unit 21, it displays the first association screen according to the first association screen display data. On the first association screen, a drop-down list or list box is arranged that lists the user ID and name information of the account with the authority type "teacher" as options for teacher candidates.

[0066] The administrator operates the terminal device 10 to select one option from the drop-down list or list box on the first association screen. The terminal device 10 then acquires the selected option as the teacher in charge information. The terminal device 10 then transmits the teacher in charge information to the information processing device 20, and the control unit 21 of the information processing device 20 receives the teacher in charge information (step S5). The control unit 21 associates the teacher in charge information with a new class ID and records the teacher in charge information in the storage device 40 so that the teacher in charge information is added to the class DB 42 (step S5).

[0067] If the administrator selects the type "normal" or "joint" in the above-mentioned object 82, the processing of the control unit 21 regarding the registration of the lesson ends after the teacher information is added. On the other hand, if the administrator selects the type "selection" in the above-mentioned object 82, after the teacher information is added, the control unit 21 extracts the user ID and name information of the account of the authority type "student" from the account DB 45, lists the user ID and name information as options for the target student candidate, and generates a list of the user ID and name information (step S6). Next, the control unit 21 transmits second association screen display data for displaying the second association screen to the terminal device 10 (step S7). The second association screen display data includes command data for displaying the user ID and name information of the account of the authority type "student" as options for the target student candidate in the second association screen display data.

[0068] When the terminal device 10 receives the second association screen display data from the control unit 21, the terminal device 10 displays the second association screen according to the second association screen display data. The second association screen has a drop-down list or list box arranged thereon that lists the user IDs and name information of accounts with the authority type "student" as options for target student candidates.

[0069] The administrator operates the terminal device 10 to select one option from the drop-down list or list box on the second association screen. The terminal device 10 then acquires the selected option as the target student information. The terminal device 10 then transmits the target student information to the information processing device 20, and the control unit 21 of the information processing device 20 receives the target student information (step S8). The control unit 21 associates the target student information with a new class ID and adds the target student information to the class DB 42 (step S8). The processing of the control unit 21 related to class registration ends after the target student information is added.

[0070] In addition, an account that has the authority type "teacher" but does not have the authority type "administrator" may or may not have the authority to register new classes in the class DB42, just like an account that has the authority type "administrator."

[0071] <Daily processing of information processing equipment> With reference to FIG. 6(b), a daily process executed by the control unit 21 of the information processing device 20 every day will be described. When the control unit 21 recognizes the current time as, for example, zero o'clock (step S11: YES), the control unit 21 refers to the class DB 42 and searches for pass information, teacher information, and target student information that are associated with expiration date information prior to the current time (step S12).

[0072] Next, the control unit 21 invalidates the display authority set for the shared folder 131 whose path is represented by the searched path information (step S13). Furthermore, the control unit 21 invalidates the display, read, write and erase authorities set for the subordinate folders and data of the shared folder 131 (step S13). Furthermore, the control unit 21 invalidates the display authority for the shared folder 131 given to the account of the user ID specified by the teacher in charge information or the target student information (step S13). Furthermore, the control unit 21 invalidates the display, read, write and erase authorities given to the account of the user ID specified by the teacher in charge information or the target student information (step S13).

[0073] <Class support functions of information processing devices> A method in which each of the students and the teacher accesses the information processing device 20 using their own terminal device 10 during class, logs in to their own account, and edits the notebooks and sticky notes will be described. Additionally, a flow of processing that the program 23a causes the control unit 21 to execute will be described. Note that the operation of the terminal device 10 and the information processing device 20 when the teacher edits the notebooks and sticky notes is similar to the operation of the terminal device 10 and the information processing device 20 when the student edits the notebooks and sticky notes.

[0074] The teacher logs in to his / her account in the same manner as the administrator logs in to his / her account. The process executed by the terminal device 10 and the information processing device 20 of the teacher at that time is the same as the process executed by the terminal device 10 and the information processing device 20 of the administrator when the administrator logs in.

[0075] After the teacher logs in, the control unit 21 of the information processing device 20 refers to the notebook management table 44 and identifies the lesson ID from the target lesson information associated with the notebook creator information that is the same as the user ID of the logged-in account. Furthermore, the control unit 21 refers to the lesson DB 42 and identifies the subject information or lesson name information associated with the identified lesson ID. The control unit 21 displays a lesson screen according to the identified subject information or lesson information on the terminal device 10. FIG. 7 shows an example of a lesson screen 241 displayed on the terminal device 10. The identified subject information or lesson information is displayed as an item in the list 241a in the lesson screen 241. When the teacher selects any subject information or lesson information from the list 40a by operating the terminal device 10, the terminal device 10 accepts the selection and transmits the acceptance of the selection to the information processing device 20. In the example shown in FIG. 7, the subject information or lesson information "Mathematics" is selected.

[0076] When the control unit 21 of the information processing device 20 receives the acceptance of the selection, it identifies the class ID associated with the selected subject information or class information by referring to the class DB 42, and identifies the notebook name information and notebook ID associated with the target class information that is the same as the class ID by referring to the notebook management table 44. The control unit 21 causes the terminal device 10 to display the identified notebook name information and notebook icon 241g in the notebook display area 241f in the class screen 241. When the teacher adds a new notebook by operating the terminal device 10, the control unit 21 causes the terminal device 10 to additionally display the notebook icon 241g, and adds the new notebook ID, notebook name information, notebook creator information, and target class information to the notebook management table 44.

[0077] The teacher selects one of the notebook icons 241g by operating the terminal device 10. The selection of the notebook icon 241g corresponds to the selection of the notebook ID corresponding to the notebook icon 241g. The terminal device 10 accepts the selection and transmits the acceptance of the selection to the information processing device 20, and the control unit 21 of the information processing device 20 receives the acceptance of the selection. The control unit 21 refers to the sticky DB 45 and reads the sticky ID, type information, and content information of the sticky associated with the attached destination information identical to the notebook ID corresponding to the selected notebook icon 241g and the sticky creator information identical to the user ID of the logged-in account. The control unit 21 causes the terminal device 10 to display a notebook screen corresponding to the selected notebook. FIG. 8 shows an example of the notebook screen 242 displayed on the terminal device 10. When displaying the notebook screen 242, the control unit 21 causes the terminal device 10 to display the sticky 2421 based on the content information and type information in the sticky display area 242c in the notebook screen 242. If the selected notebook does not have a sticky note attached, the sticky note is not displayed in the sticky note display area 242c.

[0078] When the teacher selects the sticky note 2421 by operating the terminal device 10 and edits the sticky note 2421, the control unit 21 executes an editing process for the sticky note 2421 in accordance with the teacher's operation of the terminal device 10, updates the type information and content information of the sticky note 2421 in the sticky note DB 45, and causes the terminal device 10 to update and display the edited sticky note 2421. For example, a text sticky note button 242b, a camera sticky note button 242d, a link sticky note button 242e, a file sticky note button 242f, and a dictionary sticky note button 242g are arranged on the left side of the notebook screen 242. When the teacher selects the text sticky note button 242b, the camera sticky note button 242d, the link sticky note button 242e, the file sticky note button 242f, or the dictionary sticky note button 242g by operating the terminal device 10, the terminal device 10 accepts the selection and transmits the acceptance of the selection to the information processing device 20. Then, the control unit 21 executes an editing process of a new sticky note in response to the teacher's operation of the terminal device 10, and adds the sticky note ID, the attached information, the sticky note creator information, the type information, and the content information of the new sticky note to the sticky note DB 45, and causes the terminal device 10 to additionally display the new sticky note in the sticky note display area 242c. When editing a sticky note as described above, the control unit 21 causes the terminal device 10 to display an editing screen corresponding to the type information.

[0079] Details of the processing executed by the information processing device 20 based on the program 23a when editing the notebook and sticky notes and the processing executed by the terminal device 10 in cooperation with the information processing device 20 are described in the application documents of Japanese Patent Applications Nos. 2023-000130 and 2023-029904. All of the contents of the application documents of Japanese Patent Applications Nos. 2023-000130 and 2023-029904 are incorporated by reference into the specification of this application.

[0080] A storage button 242a is arranged at the top of the notebook screen 242. The teacher selects the sticky note 2421 by operating the terminal device 10 and presses the storage button 242a. Such pressing causes the terminal device 10 to recognize an instruction to store the sticky note 2421, and the terminal device 10 transfers the instruction to store the sticky note 2421 to the information processing device 20. The control unit 21 of the information processing device 20 that receives the instruction determines the display contents based on the authority and expiration date information given to the account logged in by the teacher. Furthermore, the control unit 21 refers to the class DB 42 and determines the display contents based on the subject information or class name information within the expiration date associated with the teacher information that is the same as the user ID of the teacher's account. Then, the control unit 21 transmits screen display data for displaying the display contents to the terminal device 10. When the terminal device 10 receives the screen display data from the control unit 21, it displays the sticky note storage screen 243 as shown in FIG. 9 according to the screen display data. Icons 243a to 243c are arranged on the left side of the sticky note storage screen 243. Icon 243a is an icon of a user folder 101 assigned to the account that the teacher logged in to. Icon 243b is an icon of the school shared folder 110. Icon 243c is an icon of the teacher shared folder 120. Note that in the case of an account that a student logged in to, icon 243c is not displayed because the account is not granted permission to display the teacher shared folder 120.

[0081] A list 243h consisting of icons 243d to 243g is arranged on the left side of the sticky note storage screen 243. These icons 243d to 243g are arranged in the same row as the icons 243a to 243c so as to be arranged below the icons 243a to 243c. Subject information or lesson name information within the expiration date is displayed in the icons 243d to 243g, respectively. The icons 243d to 243g correspond to the shared folders 131 for which the teacher has given the login account display authority within the expiration date. Note that the display authority becomes invalid after the expiration date, so the icons 243d to 243g are hidden.

[0082] The teacher selects one of the icons 243a to 243g by operating the terminal device 10. Such a selection transfers a command to store the sticky note 2421 to the information processing device 20. The control unit 21 of the information processing device 20 that receives the command copies the type information and content information of the sticky note 2421 in the sticky note DB 45 to a folder corresponding to the selected icon among the icons 243a to 243g. In the example shown in FIG. 9, the icon 243e indicating the subject information or lesson name information "Mathematics" was selected by the teacher, so the control unit 21 copies the type information and content information of the sticky note 2421 as sticky information to the shared folder 131 specified by the path information associated with the subject information or lesson name information "Mathematics".

[0083] The right part of the sticky note storage screen 243 displays icons of subfolders and data registered under the folder corresponding to the selected icon among the icons 243a to 243g. In the example shown in FIG. 9, when the icon 243e displaying the subject information or lesson name information "Mathematics" is selected by the teacher, the control unit 21 causes the terminal device 10 to additionally display icons of subfolders and data registered under the shared folder 131 specified by the path information associated with the subject information or lesson name information "Mathematics" on the right part of the sticky note storage screen 243. In particular, the control unit 21 causes the terminal device 10 to additionally display on the right part of the sticky note storage screen 243 a sticky note 242m based on the sticky note information registered under the shared folder 131. In addition, when the control unit 21 copies the type information and content information of the sticky note 2421 to the shared folder 131 as sticky note information, the control unit 21 causes the terminal device 10 to additionally display on the right part of the sticky note storage screen 243 a sticky note 242n based on the sticky note information.

[0084] In addition, even if the teacher operates the terminal device 10 to instruct data other than sticky notes to be moved to the shared folder 131, copied, or newly created, the control unit 21 moves the data to the shared folder 131, copies the data, or creates a new copy.

[0085] <Summary> When the administrator registers a class, the control unit 21 of the information processing device 20 creates a new shared folder 131 to be used in that class. The control unit 21 associates the path information of the shared folder 131 with the target student information and the teacher information. As a result, the control unit 21 grants the authority to display, read, write and delete the shared folder 131 and its subordinate folders and data to the accounts of the target student and teacher specified by the target student information and teacher information. Such a shared folder 131 contributes to facilitating information sharing between the target student and the teacher.

[0086] After the expiration date, the rights to view, read, write, and delete the shared folder 131, subfolders, and data given to the accounts of the target student and the teacher in charge are invalidated. Therefore, the target student and the teacher in charge are freed from the trouble of sorting out old data. [Explanation of symbols]
