The "primary save shared folder" button 242 is temporarily saved in the shared folder of the storage unit 2000 after the "primary save in shared folder and exit" button 238a shown in FIG. 8C is pressed. It is a button for reading (reading) the file data that has been created. The "Kato-san's exclusive folder" button 243a is a button for reading (reading) file data from the user A (Kato-san)'s exclusive folder stored in the storage unit 8000 of the file management server 8. For the display of this "Kato", the display control unit 24 uses the user name transmitted from the terminal management server 5 in step S15 (see FIG. 11). In this way, when the folder selection screen 240 at the time of reading is displayed, the button 243a showing the user name of the logged-in user A is displayed by default. At the bottom of the folder selection screen 240 (see FIGS. 16A and 16C), after each folder 241,242,243a (243b) is selected, an "OK" button for confirming this selection is clicked. 246, a "Cancel" button 249 is displayed to cancel this selection.

Next, the determination unit 25 determines whether the acquisition / provision unit 28 has acquired the terminal ID from the exclusive terminal such as the IC card 3 when the folder selection screen 240 at the time of reading is displayed (step S33). ). Here, a case where the user B (Jim) who is not logged in brings his / her smartphone 4 close to the short-range communication unit 221 of the electronic blackboard 2 shown in FIG. 15 will be continuously described. In this case, if the determination unit 25 determines in step S33 that the terminal ID has been acquired (YES), the same processing as in steps S13 to S21 shown in FIG. 11 is executed. In this case, in step S113, it is not a request for login authentication but a request for authentication of the exclusive terminal which is the smartphone 4. As a result, when the terminal management server 5 determines that the exclusive terminal is valid (see step S14) and the user name (Jim) of the user B is transmitted from the terminal management server 5, the electronic blackboard 2x As shown in FIG. 16C, the display control unit 24 displays the “Jim's exclusive folder” button 243b instead of the “Kato's exclusive folder” button 243a. Further, the file data of the user B is also sent from the file management server 7 in step S20, and is stored in the storage unit 2000 of the electronic blackboard 2x by step S21. As a result, the user B is in a state where it is easy to display his / her own file data on the display 220.

Next, when the user B selects by pressing the "Jim's exclusive folder" button 243b on the folder selection screen 240 shown in FIG. 16C, and presses the "OK" button 247, the user B selects the folder. The reception unit 22 accepts the selection of the folder (step S35). As a result, the display control unit 24 displays the file selection screen 245 at the time of reading as shown in FIG. 16D (step S36). On the file selection screen 245, the file names 243b1,243b2 of the electronic file data stored in the exclusive folder of the user B are displayed. At the bottom of the file selection screen 245 (see FIGS. 16B and 16D), after the file names 243a1 (243b1) and 243a (243b2) are selected, "OK" for confirming this selection.

Next, when the user B presses and selects a desired file name on the file selection screen 245 shown in FIG. 16 (D) and then presses the "OK" button 247, the reception unit 22 receives the file. Accepts the selection of the electronic file to be read (step S37). As a result, the storage / reading processing unit 29 reads (reads) the file data related to the electronic file received in step S37 from the storage unit 2000 (step S38). Then, the display control unit 24 causes the display 220 to display an image which is the content of the file data (step 39).

On the other hand, in step S32, the user B (Jim) who is not logged in while the display control unit 24 is displaying the folder selection screen 240 as shown in FIG. 16A on the display 220. However, while the user A keeps his / her smartphone 4 away from the short-range communication unit 221 of the electronic blackboard 2 shown in FIG. 15, the user A uses the “Kato-san's exclusive folder” shown in FIG. 16 (A). When the button 243a is pressed for selection and the "OK" button 247 is pressed, the processes of steps S33 and S39 are performed from the processes of steps S33 and S39. In this case, in step S36, the file selection screen 245 shown in FIG. 16B is displayed. Also in this case, the file names 243a1,243a2 of the electronic file data stored in the exclusive folder of the user A are displayed on the file selection screen 245.

This completes the process of reading the electronic file data.

<Saving of electronic file data>
Next, the storage process of the electronic file data will be described with reference to FIGS. 17 and 18. FIG. 17 is a flowchart showing a process of saving electronic file data. FIG. 18 is an example of a screen displayed on the display of the electronic blackboard.

When the logged-in user A (Kato) presses the "save" button 235 shown in FIG. 8B, the reception unit 22 accepts the display of the folder selection screen 250 at the time of saving (step S51).

Then, the display control unit 24 displays the folder selection screen 250 as shown in FIG. 18A on the display 220 (step S52). On the folder selection screen 250, a "USB memory" button 251, a "primary save shared folder" button 252, and a "Kato-san's exclusive folder" button 253a are displayed.

Of these, the "USB memory" button 251 is a button for saving (writing) file data in the USB memory 2600 shown in FIG. The "primary save shared folder" button 252 temporarily files in the shared folder of the storage unit 2000 after the "primary save in shared folder and exit" button 238a shown in FIG. 8C is pressed. It is a button to execute the same process as when saving data. The "Kato-san's exclusive folder" button 253a is a button for transmitting and saving file data to the user A (Kato-san)'s exclusive folder stored in the storage unit 8000 of the file management server 8. Is. For the display of this "Kato", the display control unit 24 uses the user name transmitted from the terminal management server 5 in step S15 (see FIG. 11).

In this way, when the folder selection screen 250 at the time of saving is displayed, the button 253a showing the user name of the logged-in user A is displayed by default. At the bottom of the folder selection screen 250 (see FIGS. 18A and 18B), after each button 251,252,253a (253b) is selected, an "OK" button for confirming this selection is displayed. 257, a "Cancel" button 259 is displayed to cancel this selection.

Next, the determination unit 25 determines whether the acquisition / provision unit 28 has acquired the terminal ID from the exclusive terminal such as the IC card 3 when the folder selection screen 250 at the time of saving is displayed (step S53). ). Here, a case where the user B (Jim) who is not logged in brings his / her smartphone 4 close to the short-range communication unit 221 of the electronic blackboard 2 shown in FIG. 15 will be continuously described. In this case, if the determination unit 25 determines in step S53 that the terminal ID has been acquired (YES), the same processing as in steps S13 to S15 shown in FIG. 11 is executed. In this case, in step S13, it is not a request for login authentication but a request for authentication of the exclusive terminal which is the smartphone 4. As a result, when the terminal management server 5 determines that the exclusive terminal is valid (see step S14) and the user name (Jim) of the user B is transmitted from the terminal management server 5, the electronic blackboard 2x As shown in FIG. 18B, the display control unit 24 displays the “Jim's exclusive folder” button 253b instead of the “Kato's exclusive folder” button 253a. As a result, the user B can easily save the file data in his / her own folder.

Next, the user B selects the button indicating the location where the file data is to be saved from the three buttons 251,252,253b on the folder selection screen 250 shown in FIG. 16B, and "OK". When the button 257 is pressed, the reception unit 22 accepts the folder selection (step S55).

Next, the determination unit 25 determines whether the "Jim's exclusive folder" button 253b is pressed, that is, whether saving to the exclusive folder is selected (step S56). Here, when the determination unit 25 determines that saving to the exclusive folder is selected (YES), the reception unit 22 further accepts the file data to be saved (step S57).

Next, the transmission / reception unit 21 transmits the file data to be saved to the file management server 8 (step S58). In this case, the transmission / reception unit 21 also transmits the user ID of the user B (Jim). As a result, the file management server 8 receives the file data and the user ID of the user B. Then, in the file management server 8, the storage / reading processing unit 89 refers to the folder with the folder name corresponding to the user ID of the user B managed in the folder management table (see FIG. 10A). The file data to be saved is saved (step S59).

On the other hand, in step S56, when the determination unit 25 determines that saving to the exclusive folder is not selected (NO), further, the "shared folder for primary saving" button 252 is pressed, that is, temporarily. It is determined whether saving to the shared folder to be saved is selected (step S60). Here, when the determination unit 25 determines that saving to the shared folder for temporary storage is selected (YES), the reception unit 22 further accepts the file data to be saved (step S61). Then, the storage / reading processing unit 29 saves the file data to be saved in the shared folder stored in the storage unit 2000 (step S62).

On the other hand, if the determination unit 25 determines in step S60 that the "USB memory" button 251 has been pressed, that is, that saving to the shared folder for temporary storage has not been selected (YES), the reception is further received. Unit 22 receives the file data to be saved (step S63). Then, the storage / reading processing unit 29 saves the file data to be saved for the predetermined file stored in the recording medium 2100 (step S64).

Since the electronic blackboard 2x generates the file name when the file is saved, the user does not have to enter the file name. The file name at this time can be realized by acquiring the date and time from the electronic clock built in the electronic blackboard 2x and generating the file name "iwb-yyyymmdd-HHMMSS.pdf", for example. Here, yyyy, mm, dd, HH, MM, and SS indicate the year, month, day, hour, minute, and second at the time of acquisition of the date and time, respectively. In step S58, this file name is also transmitted together with the file data.

This completes the process of saving the electronic file data.
