Next, the flow of processing of the document management system of the present invention will be described with reference to FIGS.
FIG. 4 is a flowchart showing the file list display process from the login process of the client PC in this embodiment.
Note that the processing of this flowchart is realized by the CPU 201 of the client PC 101 reading and executing a program recorded in the ROM 202 or the external memory 211 so as to be readable by a computer. In the figure, S401 to S407 indicate steps.
4 is a process that is started when a client PC (tablet PC) 101 logs in to the document management system of this embodiment.

  In step S401, the CPU 201 of the client PC 101 displays a login screen as shown in FIG. 10 on the display 210, and accepts server selection, user name, and password input.

FIG. 10 is an example of a login screen displayed on the client PC in this embodiment.
As shown in FIG. 10, the login screen includes a server selection pull-down 1001, a user name input field 1002, a password input field 1003, and a [Login] button 1004. The user selects the server name to be connected from the server selection pull-down 1001, and presses the [Login] button 1004 with the user name entered in the user name entry field 1002 and the password entered in the password entry field 1003 to select the server. It is possible to log in to the server selected by the pull-down 1001. Note that the server selection pull-down 1001 can also select the client PC 101 itself. In this case, it is possible to log in to the client PC 101 and use the document management system of this embodiment offline.

  The CPU 201 of the client PC 101 that has received the input executes an authentication operation of the selected client PC or server with the input user name and password. If the authentication is OK, the CPU 201 of the client PC 101 permits the use and advances the process to S402. On the other hand, in the case of authentication NG, the CPU 201 of the client PC 101 prohibits use and ends the processing of this flowchart (not shown).

  Next, in step S <b> 402, the CPU 201 of the client PC 101 determines whether there is an electronic file reserved for uploading, which will be described later, among the electronic files in the client PC 101 (for example, stored in the external memory 211). Judging. Specifically, when an electronic file having information as shown in FIG. 7 exists, the item No. 8 (presence / absence of upload reservation) in FIG. 7 is confirmed, and the item No. 8 is “1”, that is, upload It is determined whether or not there is an electronic file that is reserved for upload depending on whether or not there is a reservation.

FIG. 7 is a diagram illustrating an example of a document information file according to the present embodiment.
The document information file (FIG. 7) is a file provided for each electronic file downloaded from the document management server, and is stored in the external memory 211 of the client PC 101 or the like.

  The document information file (FIG. 7) may be a file different from the electronic file downloaded from the document management server, or the electronic file downloaded from the document management server may be held as attribute information.

  As shown in FIG. 7, the document information file includes No, OU code, cabinet ID, document ID, document name, document size, document download date, upload reservation presence, upload destination server ID, upload destination cabinet ID, upload destination folder. And information such as document update date and time.

Hereinafter, the description returns to the flowchart of FIG.
If it is determined in S402 that there is no electronic file that is reserved for uploading (in the case of "None" in S402), the CPU 201 of the client PC 101 shifts the processing to step S405 as it is.

  On the other hand, if it is determined in S <b> 402 that there is an electronic file that is reserved for upload (“Yes” in S <b> 402), the CPU 201 of the client PC 101 shifts the process to step S <b> 403.

  In step S403, the CPU 201 of the client PC 101 determines whether the upload destination server of the electronic file that is reserved for uploading is a connection server. Specifically, the CPU 201 of the client PC 101 determines that the item No. 9 in FIG. 7 (upload destination server) is included when the document information file of the electronic file that is determined to be reserved for upload has information as shown in FIG. ID) is confirmed, and the server ID corresponding to No. 9 is acquired. Furthermore, the CPU 201 of the client PC 101 acquires server information (FIG. 8) corresponding to the acquired server ID, and determines whether the server corresponding to the acquired server information is a connection server.

  Note that the connection server is a server that has been selected and logged in by the pull-down in FIG. 10 in the login process in S401. The server information corresponding to the server ID can be acquired from No. 1 in FIG. 8, and the server information corresponding to the server name can be acquired from No. 2 in FIG.

FIG. 8 is a diagram illustrating an example of server information according to the present embodiment.
The server information (FIG. 8) is information held for each document management server, and is stored in the external memory 211 of the client PC 101 or the like.
As shown in FIG. 8, the server information includes information such as a server ID, a server name, a host, an OU code, an authentication code, and a cabinet ID.

Hereinafter, the description returns to the flowchart of FIG.
In step S403, when it is determined that the electronic file upload destination server is not a connection server (in the case of “different” in S403), the CPU 201 of the client PC 101 shifts the process to step S405 as it is.

  On the other hand, when it is determined in step S403 that the upload destination server of the electronic file is a connection server (in the case of “same” in S403), the CPU 201 of the client PC 101 shifts the processing to step S404.

  In step S404, the CPU 201 of the client PC 101 uploads the upload reserved electronic file to the connection server (document management server) (reserved upload function). The upload destination folder stored in the document management server is a folder registered in No. 11 (upload destination folder) of the document information file (FIG. 7) corresponding to the electronic file reserved for uploading. By the upload processing in S404, it becomes possible to upload the electronic file reserved for upload immediately after login.

  In step S405, the CPU 201 of the client PC 101 checks the date / time registered in the document download date / time (No. 7 in FIG. 7) of the document information file corresponding to the electronic file downloaded from the document management server, and sets the client setting. An electronic file outside the range of the terminal storage period of information (No. 5 or 6 in FIG. 9) is searched, and the corresponding file is deleted. Note that the terminal storage period is a period in which the electronic file downloaded from the server can be stored in the client PC in the client PC, and is also an expiration date for browsing the electronic file in the client PC.

FIG. 9 is a diagram illustrating an example of client setting information according to the present embodiment. The client setting information (FIG. 9) is information held for each client PC 101.
As shown in FIG. 9, the client setting information includes an administrator user ID, an application login setting, an application login password, a terminal storage period setting, a terminal storage period (number of days), a terminal storage period (time), an editing time limit, and a local holder use Information such as the expiration date, login update confirmation, external application cooperation, setting update date and time is stored, and the terminal storage period and the like can be confirmed.

  In the file deletion process of S405, the CPU 201 of the client PC 101 determines that the upload destination server (No. 9 in FIG. 7) is not the current connection server, and whether there is an upload reservation (No. 8 in FIG. 7). For example, the electronic file corresponding to the document information file with “Yes (1)” is not deleted even when the terminal storage period has passed, and the next time the connection server is the upload destination server (No. 9 in FIG. 7). The electronic file is stored in the client PC 101 until the upload is completed.

  Next, in step S406, the CPU 201 of the client PC 101 updates the data with the connection server if the update confirmation column upon login (No. 9 in FIG. 9) of the client setting information is “1”.

  Specifically, the CPU 201 of the client PC 101 also deletes the corresponding file in the client PC 101 when the corresponding electronic file no longer exists from the connection server. Further, when the corresponding electronic file is newer than the corresponding file in the client PC 101, the CPU 201 of the client PC 101 replaces the corresponding electronic file in the client PC 101 with the corresponding file in the connection server. Note that the CPU 201 of the client PC 101 does not perform anything in the update confirmation processing in S406 if the login confirmation update column (No. 9 in FIG. 9) of the client setting information is “0”.

  Next, in step S407, the CPU 201 of the client PC 101 displays an electronic file list display screen as shown in FIG. 11 on the display 210, and subsequently executes various processes that are not described here.

FIG. 11 is a diagram showing an example of a file list display screen displayed on the client PC in the present embodiment.
As shown in FIG. 11, the list display screen has a tree display 1101, a file list display 1102, a “logout” button 1103, an “upload” button 1104, and a “download button” 1105.

  The tree display 1101 displays the folder structure in the connection server and the client PC 101 acquired from the connection server. A file list display 1102 displays a list of files in the folder selected in the tree display 1101.

[Logout] button 1103 is for logging out from the connection server.
An “Upload” button 1104 is used to upload a file in the client PC 101 to the connection server. When the [Local] folder is selected in the tree display 1101 and a file is selected in the file list display 1102 and the [Upload] button 1104 is pressed, the CPU 201 of the client PC 101 displays the file list display 1102 in the file list display 1102. The selected file is uploaded from the client PC 101 to the connection server.

  A “Download” button 1105 is used to download a file in the connection server to the client PC 101. When one of the folders in the connection server is selected in the tree display 1101 and a file is selected in the file list display 1102, when the [Download] button 1105 is pressed, the CPU 201 of the client PC 101 displays the file list. The file selected in 1102 is downloaded from the connection server to the client PC 101.

  It should be noted that the CPU 201 of the client PC 101 uses the electronic file list (No. 8 in FIG. 7 is registered as “1” in the electronic file list displayed by the file list screen display process in S407). (Electronic file) is controlled so as not to be displayed (viewing restriction function). This is because an electronic file that is reserved for uploading is an electronic file whose storage period has expired, and thus should not be viewed by the user.

  As this process does not display the electronic file reserved for uploading in the electronic file list, the user cannot view the electronic file whose retention period has passed, but the next time the user accesses the connection server, Can be controlled to be automatically uploaded, and an electronic file can be uploaded in consideration of security.

Next, the flow of upload processing after editing an electronic file will be described with reference to FIG.
FIG. 5 is a flowchart showing upload processing of the client PC 101 in the embodiment of the present invention.
Note that the processing of this flowchart is realized by the CPU 201 of the client PC 101 reading and executing a program recorded in the ROM 202 or the external memory 211 so as to be readable by a computer. In the figure, S501 to S507 indicate steps.

5 is a process started when the user opens an electronic file in a state where it can be edited / updated in the client PC (tablet PC) 101.
In step S501, the CPU 201 of the client PC 101 accepts editing of an electronic file (not shown), and upon receiving a save instruction, saves the electronic file in the client PC 101 (local save).

  In step S502, the CPU 201 of the client PC 101 updates the document information file of the electronic file stored locally in step S501. For example, the document size (No. 6), the document update date / time (No. 12), etc. in FIG. 7 are updated. Of course, the document name (No. 5) and the values of other items may also be updated.

  In step S503, the CPU 201 of the client PC 101 displays a screen (not shown) and accepts selection of a document to be uploaded. Normally, the electronic file edited in S501 is selected, but another electronic file may be selected and uploaded simultaneously.

  In step S504, the CPU 201 of the client PC 101 reads the document information file of the electronic file selected as the document to be uploaded, and checks the connection status of the document management server with the upload destination server ID (No. 9 in FIG. 7). Then, it is determined whether or not the document management server can be connected (including already connected).

  When it is determined that the upload destination document management server can be connected (in the case of “online” in S504), the CPU 201 of the client PC 101 shifts the processing to step S505. If connection is possible but not, the CPU 201 of the client PC 101 connects to the upload destination document management server at this timing.

  In step S505, the CPU 201 of the client PC 101 receives from the user the selection of the storage destination folder of the connected document upload destination document management server. The reception screen for the storage folder will be described with reference to FIG.

FIG. 12 is a diagram illustrating an example of an upload destination selection screen displayed on the client PC in the present embodiment.
As illustrated in FIG. 12, the upload destination selection screen includes a display 1201 of a document file to be uploaded, a folder name column 1202 for the upload destination, and an upload button 1203.
In the upload destination folder name column 1202, the folder name of the connection server to be uploaded by the user is input or selected from a pull-down menu.

Returning to the flowchart of FIG.
In step S506, when the CPU 201 of the client PC 101 detects that the upload button 1203 (FIG. 12) is pressed by the user, the document file to be uploaded displayed on the document file display 1201 (in the case of FIG. Document 1. PDF ") is uploaded to the folder of the connection server input in the folder name column 1202, and the processing of this flowchart is terminated.

  If it is determined in S504 that the upload destination document management server cannot be connected (in the case of “offline” in S504), the CPU 201 of the client PC 101 shifts the processing to step S507.

  In step S507, the CPU 201 of the client PC 101 displays an error screen as shown in FIG. 13 on the display 210, notifies the user that uploading is not possible, and ends the processing of this flowchart.

FIG. 13 is a diagram illustrating an example of an upload error screen displayed on the client PC in the present embodiment.
As shown in FIG. 13, the upload error screen has a message 1301 for notifying the user that uploading cannot be performed and a confirmation button 1302.

Next, the flow of processing when the client PC 101 is activated will be described with reference to FIG.
FIG. 6 is a flowchart for explaining processing when the client PC 101 is activated in the embodiment of the present invention.
Note that the processing of this flowchart is realized by the CPU 201 of the client PC 101 reading and executing a program recorded in the ROM 202 or the external memory 211 so as to be readable by a computer. In the figure, S601 to S607 indicate each step.

6 is a process that is started when the client PC (tablet PC) 101 is activated.
First, in step S601, the CPU 201 of the client PC 101 confirms whether a terminal storage period is set for the client PC 101. Specifically, the CPU 201 of the client PC 101 confirms whether “No time limit (1)” is set in No. 4 of FIG. 9, and No. 4 of FIG. If the terminal storage period is set, and No. 4 in FIG. 9 is “no expiration (0)”, it is determined that the terminal storage period is not set.

  If it is determined that the terminal storage period is not set (in the case of “None” in S601), the CPU 201 of the client PC 101 shifts the process to step S607 as it is.

  On the other hand, when it is determined that the terminal storage period is set (in the case of “Yes” in S601), the CPU 201 of the client PC 101 shifts the processing to step S602.

  In step S602, the CPU 201 of the client PC 101 checks whether there is an unuploaded document. Specifically, the CPU 201 of the client PC 101 determines whether there is an electronic file that has been updated after being downloaded from the document management server (update determination). More specifically, the CPU 201 of the client PC 101 compares the document download date / time (No. 7 in FIG. 7) and the document update date / time (No. 12 in FIG. 7) of the document information file of the electronic file on the client PC 101 to obtain the document. An electronic file whose update date is newer than the document download date is searched for as an unuploaded document. The document download date / time (No. 7 in FIG. 7) is also updated when the electronic file is uploaded, and the document update date / time (No. 12 in FIG. 7) is also updated when the electronic file is downloaded.

  If it is determined that there is no unuploaded document (“No” in S602), the CPU 201 of the client PC 101 proceeds to step S607 as it is.

  On the other hand, if it is determined that there is an unuploaded document (“Yes” in S602), the CPU 201 of the client PC 101 shifts the process to step S603.

The processing of S602 will be described with reference to FIG.
FIG. 15 is a diagram showing a list of document information files of each electronic file downloaded to the client PC 101, and each item in the figure is the same as the document information file of FIG.

  Of the electronic files in the file list of FIG. 15, the electronic files whose update date and time are newer than the download date and time are No. 1, No. 2, and No. 3. Since there are these three files, in the example of FIG. 15, it is determined in S602 that there is an unuploaded document (“present”), and the process proceeds to step S603.

  In step S603, the CPU 201 of the client PC 101 reads the client setting information (FIG. 9), starts the terminal storage period (Nos. 5 and 6), the document download date (No. 7 in FIG. 7), and the client PC 101. From the relationship with the date and time, it is determined whether the electronic file is within the storage period or outside the storage period (expiration date determination). Processing for determining whether the electronic file is within the storage period or outside the storage period will be described with reference to FIGS.

  The No. 1 electronic file “Document 1.PDF” in the list of FIG. 15 has a document download date of “October 15, 2012”, and the terminal storage period of this client PC 101 is “10 days”. . Therefore, if the date on which the client PC 101 was started is before “October 25, 2012”, the electronic file “Document 1.PDF” of No. 1 is “within the retention period”. On the other hand, if the date when the client PC 101 was started up is “October 26, 2012” or later, the No. 1 electronic file “Document 1.PDF” is “out of storage period”.

  If it is determined in S603 that all the electronic files are “within the storage period” (in the case of “within the storage period” in S603), the CPU 201 of the client PC 101 shifts the process to step S607 as it is.

  On the other hand, if it is determined in S603 that one of the electronic files is “outside the storage period” (there is at least one electronic file “outside the storage period”) (in the case of “outside the storage period” in S603) The CPU 201 of the client PC 101 shifts the processing to step S604.

  In step S604, the CPU 201 of the client PC 101 displays on the display 210 a screen (FIG. 14) that warns the user that there is an electronic file that is automatically deleted. An example of a warning screen will be described with reference to FIG.

FIG. 14 is a diagram showing an example of a deletion target file warning screen displayed on the client PC in the present embodiment.
As shown in FIG. 14, the deletion target file warning screen in this embodiment is a message 1401 that warns the user that there is an electronic file to be automatically deleted, a deletion target document column 1402, a no button 1403, yes It has a button 1404.

  In the deletion target document column 1402 of FIG. 14, the names of the electronic files determined to be “out of storage period” in S603 are displayed. If there is no upload reservation, these files are displayed after login. A warning that it will be deleted is displayed.

  When the CPU 201 of the client PC 101 detects on the warning screen (FIG. 14) that the “No” button 1403 has been pressed by the user, it determines in step S605 that there is no upload reservation setting (“none” in S605). Then, the process proceeds to step S607 as it is.

  On the other hand, when it is detected on the warning screen (FIG. 14) that an electronic file that the user does not want to delete is selected from the deletion target document column 1402 and the “Yes” button 1404 is pressed, the CPU 201 of the client PC 101 In step S605, it is determined that there is an upload reservation setting ("Yes" in S605), and the process proceeds to step S606.

  In step S606, the CPU 201 of the client PC 101 registers the upload reservation presence / absence item (No. 8 in FIG. 7) of the document information file of the electronic file selected in the deletion target document column 1402 as “present (1)”. Then, the process proceeds to step S607. With this process, even if an electronic file edited by the user cannot be uploaded within the “save period”, the electronic file is automatically deleted at the next server connection without being deleted. .

  Next, in step S607, the CPU 201 of the client PC 101 performs the processing in FIG. 4 (S401 to S407).
