Description

  The present invention relates to an apparatus for displaying information related to data stored in a storage device.

  In recent years, image forming apparatuses having a box function have begun to spread. According to such a function, a storage area called “personal box” or the like can be provided for each user. Each user can store document data such as his / her image data or document data in his / her personal box.

  In addition, image forming apparatuses are becoming more and more multifunctional, including functions such as a scanner, a FAX, a printer, and a network connection. Such a multifunctional image forming apparatus is called a multifunction peripheral or MFP (Multi Function Peripherals).

  A method for efficiently using these functions has also been proposed. According to the method described in Patent Literature 1, job management information input by a user is displayed according to a confirmer. If the confirmer is the administrator or the input person of the job, all items of the management information are displayed, and if it is other than that, a part of the management information is deleted and displayed. Thereby, management information can be displayed appropriately.

  According to the method described in Patent Literature 2, when image formation is performed by the image forming apparatus, user authentication is performed by wireless communication between the image forming apparatus and the portable terminal. User authentication can be performed in a short time without forcing the user to perform work.

  According to the method described in Patent Document 3, user identification information is added to input image data and stored in a hard disk. Then, the input user identification number and the user identification number added to the image data are collated, and only the name of the image data with the matching user identification number is displayed based on the collation result. Thereby, the user can easily know his / her image data.

  According to the method described in Patent Document 4, the MFP generates PDA data based on the image data stored in the personal box. Then, in response to a request from the PDA, the PDA data is transmitted to the PDA. Thereby, the data stored in the personal box can be browsed by the PDA even from a remote place.

According to the method described in Patent Document 5, by performing user authentication using an ID card, it is possible to perform user restriction when a document is shared by a plurality of users.
JP 2003-189036 A JP 2003-94777 A JP 2002-361970 A JP 2002-354164 A JP 2002-240398 A

  In addition to the above, the storage capacity of storage devices such as hard disks of image forming apparatuses is increasing. In addition, document data stored in a personal box of another image forming apparatus can be used via a network. This greatly increases the number of document data that can be used by the user. Therefore, it has become more difficult for users to find document data that they can use.

  However, in the methods described in Patent Documents 1, 2, 4, and 5, it is difficult to easily find document data that can be used by the user. Further, according to the method described in Patent Document 3, although the user's own image data can be easily found, the image data of other users that can be used by the user cannot be found.

  The present invention has been made in view of such a problem, and an object of the present invention is to make it easier to find data usable by a user from data stored in a storage device than ever before.

  The display device according to the present invention includes access right information relating to access right of each data stored in a storage device and data information acquisition means for acquiring data identification information for identifying each data, and the data identification of each data Display means for displaying information in a display mode corresponding to the access right indicated in the access right information of each data.

  Preferably, user information acquisition means for acquiring user identification information for identifying a user, wherein the data information acquisition means includes an access right given to the user corresponding to the user identification information as the access right information. Get the access right information shown.

  This display device can be applied to an image forming apparatus. For example, at least one of a process for printing a document, a process for displaying a document, a process for transferring document data of a document, and a process for deleting the document data is included. It can be applied to an image forming apparatus having processing control means for executing and controlling execution of these processes. In this case, the process control means performs control for executing any of the processes on the document data corresponding to the data identification information selected by the user from the data identification information displayed by the display means. .

  Alternatively, in the image forming apparatus, the display unit displays a button for each process together with the data identification information of each data, and the user first selects the data identification information and the buttons displayed. When any one of the data identification information is selected, the user selects the button display mode of the process that is not permitted to be executed on the document data corresponding to the data identification information. If the user selects any of the buttons first, the display mode of the data identification information of the document data that is not permitted to execute the processing corresponding to the button is changed. The processing control means is changed so that the user cannot select the data identification information. For the document data corresponding to the data identification information THE selects performs control for executing the processing corresponding to the button that the user has selected with the data identification information. Alternatively, when the user selects any one of the data identification information from the displayed data identification information and the button, the display unit executes the document data corresponding to the data identification information. When the display mode of the button of the processing that cannot be performed is changed so that the user cannot select the button, and the user selects any of the buttons first, the button corresponding to the button The display mode of the data identification information of the document data that cannot be processed is changed so that the user cannot select the data identification information.

  Hereinafter, the processing contents of each unit in FIG. 3 and the like will be described with reference to an example in which the user operates the multifunction device 1A to use document data stored in each multifunction device 1 provided in the document sharing system 100. explain.

  4 is a diagram illustrating an example of a logon screen HG1, FIG. 5 is a diagram illustrating an example of a box selection screen HG2, FIG. 6 is a diagram illustrating an example of a document selection screen HG3, and FIG. 7 is a diagram illustrating an example of management data 73. FIG. 8 is a diagram showing an example of changing the display mode of the document selection screen HG3.

  The system control unit 31 exchanges data with each unit of the network control unit 32 or the management data generation unit 37 and gives commands to the respective units. That is, the entire multifunction device 1 is controlled.

  The user interface control unit 36 performs processing for displaying the logon screen HG1 in FIG. 4, the box selection screen HG2 in FIG. 5, and the document selection screen HG3 in FIG. 6 on the display surface of the operation panel 11b. Furthermore, a process of detecting a touched (pressed) position on the display surface of the operation panel 11b is performed. These screens are displayed according to a user operation or the like in the following procedure.

  When the user selects a document list menu from a menu screen (not shown), the user interface control unit 36 performs a process for displaying the logon screen HG1 in FIG. Here, the user inputs his / her user ID and password in the text boxes TX11 and TX12 by pressing a button of the button group BG1, respectively.

  Then, the network control unit 32 requests the other multifunction devices 1 (1B, 1C,...) To transmit information related to document management. At this time, the input user ID and password are transmitted to each multifunction device 1 for notification.

  The multifunction device 1 that has received the request performs user authentication based on the user ID and password transmitted together. If it can be confirmed that the user is correct, the document name (document name), creation date and time, number of pages, creator, and storage location box of each document stored in the box provided in the multifunction device 1 are indicated. The document information 71 and the access right information 72 indicating the access right of each document given to the user are transmitted to the requesting MFP 1A.

  In the multifunction device 1 </ b> A, the network control unit 32 receives the document information 71 and the access right information 72 from the other multifunction device 1. Further, the hard disk control unit 35 reads out the document information 71 of each document and the access right information 72 of the user stored in a box provided in the multifunction machine 1A itself. Then, the management data generation unit 37 generates management data 73 as shown in FIG. 7 based on the received or read information.

  The management data 73 includes document identification information and access restriction information. The document identification information is based on the document information 71, and the access restriction information is based on the access right information 72.

  In the present embodiment, access rights are provided for four types of processing: “print”, “display”, “transfer”, and “delete”. “O” means that the user who has logged on to the MFP 1A is permitted to execute the process, and “X” means that the process is prohibited. For example, in FIG. 7, the document “document 2” stored in the box “User A BOX” of the multifunction peripheral 1B is “print = ×”, “display = O”, “transfer = ×”, “ Since “delete = ×” is set, only “display” processing is permitted for the user, and “print”, “transfer”, and “delete” processing is not permitted. .

  Note that the multifunction device 1 may not transmit the document information 71 and the access right information 72 to the multifunction device 1A for a document that is “x” for all processes, such as “document X”.

  The user interface control unit 36 performs processing for sequentially displaying the box selection screen HG2 in FIG. 5 and the document selection screen HG3 in FIG. 6 based on the generated management data 73.

  That is, first, a box selection screen HG2 having a button group BG21 composed of buttons for each multifunction device 1 (1A, 1B, 1C,...) Is displayed. When one of the buttons is pressed, a button group BG22 including buttons for each box provided in the multi function device 1 corresponding to the button is additionally displayed next to the button group BG21. For example, when the button of “MFP 1B” is pressed, a button group BG22 including buttons in which the box names of the boxes provided in the MFP 1B are written is additionally displayed.

  When any button is pressed from the button group BG22, as shown in FIG. 6, a document list LT3 stored in a box corresponding to the button and a document made up of a button group BG3 for selecting a process. The selection screen HG3 is displayed.

  Here, the user selects both the document to be used and the processing method (usage method, operation method) thereof. The document may be selected first, or the processing method may be selected first.

  In the former case, the user interface control unit 36 determines the access right given to the user for the selected document based on the management data 73, and determines the button group BG 3 according to the content of the access right. Change the display. For example, as shown in FIG. 8A, when the row of the document “document 5” is selected from the list LT3, “transfer” and “delete” are permitted for the user. Therefore, the buttons corresponding to these processes (operations) are changed to shaded display so that they cannot be selected. Alternatively, these buttons may be hidden.

  In the latter case, the document permitted for the user to perform the selected process is determined, and the display of the row of the list table LT3 is changed according to the contents. For example, as shown in FIG. 8B, when a button corresponding to the “transfer” process is selected from the button group BG3, a document that is permitted to be transferred to the user is “document”. Since only “1” and “Document 3”, the other document lines are changed to shaded display so that they cannot be selected. Alternatively, the characters in these columns may be hidden.

  In FIG. 8A, the user presses a button corresponding to a desired process from buttons that are not shaded. Alternatively, in FIG. 8B, a line corresponding to a document to be used is selected by pressing from lines that are not shaded.

  Then, the network control unit 32, the engine control unit 33, the hard disk control unit 35, and the user interface control unit 36 perform the selected process on the selected document as follows.

  When “print” processing is selected on the document selection screen HG3, the network control unit 32 accesses the multi-function device 1 having the document data of the selected document and downloads the document data. However, when the MFP 1A itself has the document data, the hard disk control unit 35 calls the document data from the box. Then, the engine control unit 33 controls the printing unit 12 to perform document printing processing based on the downloaded or called document data.

  When “display” is selected, the network control unit 32 or the hard disk control unit 35 acquires document data, as in the case where “print” is selected. Then, the user interface control unit 36 performs processing for displaying the contents of the document on the display surface of the operation panel 11b based on the document data.

  When “Transfer” is selected, the network control unit 32 instructs the MFP 1 having the document data to transfer the document data of the selected document to the device designated by the user.

  Upon receiving the command, the multifunction device 1 transfers document data as follows. When another multifunction device 1 or a personal computer is designated as the transfer destination, the document data is transferred by FTP (File Transfer Protocol) or SMB (Server Message Block). When an e-mail address is designated, an e-mail attached with the document data is transmitted to the e-mail address. When a FAX number is designated, the document data is converted into FAX data and transmitted. The document data after transfer (transmission) may be deleted from the original storage location or may be left as it is.

  Alternatively, the MFP 1A may once acquire the document data and transfer it to a designated device. That is, the MFP 1A may relay document data.

  When “Erase” is selected, the network control unit 32 instructs the MFP 1 having the document data to delete (delete) the document data of the selected document. However, when a document included in the MFP 1A itself is selected, the hard disk control unit 35 executes a process for deleting the document data of the document from the box.

  FIG. 9 is a flowchart for explaining an example of the process flow of the multifunction peripheral 1A, FIG. 10 is a flowchart for explaining an example of the operation button update process, and FIG. 11 is a flowchart for explaining an example of the list update process. .

  Next, a processing flow of the multifunction device 1A when the user of the multifunction device 1A uses document data will be described with reference to a flowchart.

  When the user identification information (user ID) and password are input to the logon screen HG1 in FIG. 4 (# 1 in FIG. 9), the multi-function device 1A uses the user ID and password as another multi-function device 1 (1B, 1C). ,...) (# 2).

  Then, the other multifunction device 1 transmits the document information 71 of the stored document and the access right information 72 of the user to the multifunction device 1A. When the MFP 1A receives the document information 71 and the access right information 72 and calls the document information 71 and the access right information 72 of each document stored in the MFP 1A itself (# 3), FIG. 7 is generated (# 6). However, if user authentication is not obtained in all the multifunction devices 1 (Yes in # 4) or there is no document (Yes in # 5), the process is terminated.

  Based on the generated management data 73 and the like, the box selection screen HG2 in FIG. 5 and the document selection screen HG3 in FIG. 6 are sequentially displayed (# 7). Then, it waits for selection of a document that the user wants to use and its usage (processing method) (# 8).

  Here, if the user first selects any row in the list LT3 (No in # 9), a button corresponding to the access right given to the user for the document corresponding to the row is displayed. The display of the group BG3 is changed (# 10).

  That is, as shown in FIG. 10, by referring to the management data 73, it is determined what operation (processing) the user can perform on the document (# 101), and FIG. In this way, the button of the process without the execution authority is changed to a shaded display (# 102).

  If the user selects a button that is not shaded (that is, a button corresponding to a process with execution authority) (Yes in # 103 and # 104), the process returns to FIG. 9 and is selected on the document selection screen HG3. The selected process is executed with the document (# 12). When the user reselects another row (No in # 103 and # 104 in FIG. 10), the processes in steps # 101 and # 102 are performed again for the document corresponding to the row.

  On the other hand, when the user first selects any button in the button group BG3 on the document selection screen HG3 (Yes in # 9 in FIG. 9), the display of the list LT3 is changed (# 11).

  That is, as shown in FIG. 11, by referring to the management data 73, a document that is permitted to perform processing corresponding to the button and a document that is not permitted are discriminated (# 111), and FIG. As in b), the line corresponding to the document that is not permitted to be processed is changed to a shaded display (# 112).

  If the user selects a line that is not shaded (that is, a document that is permitted to be processed) (Yes in # 113 and # 114), the process returns to FIG. 9 and is selected on the document selection screen HG3. For the selected document, the process selected together with the document is executed (# 12). When the user reselects another button (No in # 113 and # 114 in FIG. 11), the processes in steps # 111 and # 112 are performed again for the process corresponding to the button.

  According to the present embodiment, data that can be used by the user is determined according to the access right of the user, and information related to the data is displayed. Thereby, the user can find his / her desired document from documents stored in the storage device more easily than in the past.

  Further, the display mode of buttons corresponding to processes that can be executed on the document selected by the user is made different from the display mode of buttons corresponding to processes that cannot be executed. Alternatively, the display mode of the identification information of the document that can execute the process selected by the user is different from the display mode of the identification information of the document that cannot be executed. Thereby, the user can find a desired document more easily.

  FIG. 12 is a view showing a modification of the document selection screen HG3, and FIG. 13 is a view showing an example of the directory selection screen HG4.

  In the present embodiment, one MFP and one box are selected in FIG. 5, but a plurality of boxes provided in one or a plurality of MFPs may be selected at a time. In this case, instead of the document selection screen HG3 in FIG. 6, a document selection screen having a list LT3 ′ indicating the storage location (URL (Uniform Resource Locator) or path) as well as the document name as shown in FIG. HG3 ′ may be displayed.

  When the logged-on user's boxes are provided in a plurality of multifunction peripherals 1, the user simply performs a predetermined operation (for example, by pressing a predetermined button), and the documents stored in these boxes are stored. Document names and the like may be displayed on the list LT3.

  When the box corresponds to a hierarchical structure such as a directory structure, a directory selection screen HG4 including a directory list LT4 in the box and a button group BG4 as shown in FIG. 13 may be displayed. .

  When the user selects any directory from the list LT4 and selects the “Open” button, the user interface control unit 36 selects a document selection screen having a list LT3 of documents belonging to the directory. HG3 (see FIG. 6) is displayed. When the “display document” button is selected, a document selection screen HG3 having a document list LT3 directly under the box (root) is displayed. When the “display all” button is selected, a document selection screen HG3 having a list LT3 of all documents in the box is displayed.

  However, when a directory is selected from the list LT4, the user interface control unit 36 determines the access right given to the user for each document belonging to the directory. If all processes (operations) are prohibited for all the documents belonging to the directory, the “Open” button is changed to shaded display so that it cannot be selected.

  Alternatively, the user can select one of the directories after pressing the “Open” button first. In this case, the user interface control unit 36 determines the access right given to the user for the documents belonging to each directory. If all the processes (operations) are prohibited for all the documents belonging to the directory, the display state of the list LT4 is changed so that the directory line is shaded.

  In the present embodiment, the user uses the document data stored in the multifunction device 1A and the other multifunction device 1 by operating the multifunction device 1A. However, the user operates the personal computer or the workstation to obtain the document data. It is also possible to use it. In this case, the document selection screen HG3 shown in FIG. 6 is displayed on the personal computer or workstation.

  Also, information related to document data stored in a personal computer or workstation is displayed in a list on the document selection screen HG3, etc., in the same way as document data stored in the box of the multifunction device 1, and is used by the user. Is also possible.

  The display of the list LT3 and the button group BG3 on the document selection screen HG3 may be changed according to the specifications of the multifunction machine 1A and the type or format of document data. For example, in the multi-function peripheral 1A that does not have both a printing function based on data of a certain file type X and a color printing function, when a file type X document or a color document is selected from the list LT3 first, Regardless of the contents of the access right, change the “Print” button to shaded display. In the same multifunction machine 1A, when the “print” button is selected first, the lines of the file type X document and the color document are changed to shaded display or the like.

  In this embodiment, the multi-function device 1 that can perform four types of processing of printing, displaying, transferring, and deleting a document has been described as an example. However, the present invention may be applied to a multi-function device that performs other processing. Can be applied. For example, the present invention can also be applied to a multi-function peripheral capable of executing processing such as changing the resolution or format of a document image or copying document data. In this case, for each of these processes, the access right (access control) is set in the same manner as the above four types of processes, and the display mode of each component of the document selection screen HG3 in FIG. 6 is changed accordingly.
