The operation unit 34 includes, for example, a menu key that calls a menu displayed on the screen of the display unit 32, an arrow key that moves the focus in the GUI that configures the menu, a determination key that performs a confirming operation on the GUI that configures the menu, It is equipped with a start key.

A touch panel 35 is overlaid on the screen of the display unit 32. The touch panel 35 is a so-called resistive film type or electrostatic capacitance type touch panel, detects a touch (touch) of a user's finger or the like on the touch panel 35 together with the touch position, and detects a GUI on the screen of the display unit 32. Enter user instructions. Therefore, the touch panel 35 plays a role as an operation unit for inputting a user operation on the screen of the display unit 32.

The network communication unit (NW communication unit in FIG. 2) 36 transmits/receives various data to/from other terminal devices (not shown) through the network N. The facsimile communication unit (FAX communication unit in FIG. 2) 37 transmits/receives image data to/from another image forming apparatus, a facsimile apparatus (not shown) or the like through the network N.

The storage unit 38 includes a RAM, a large-capacity HDD (Hard Disk Drive), etc., and stores various data and programs.

The control unit 31 includes a processor, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The processor is a CPU (Central Processing Unit), MPU, ASIC, or the like. The control unit 31 functions as a main control unit 41, a display control unit 42, and a communication control unit 43 when the program stored in the ROM or the storage unit 38 is executed by the processor. Note that each of the above-described configurations of the control unit 31 may be configured by a hardware circuit instead of the operation based on the program. The main control unit 41, the display control unit 42, and the communication control unit 43 correspond to the "control unit" in the claims.

The main control unit 41 controls the overall operation of the image forming apparatus 10. In addition, the main control unit 41 has a well-known OCR function (an example of a character recognition function in the claims) that analyzes an image represented by image data and recognizes a character included in the image. An application program and data for this OCR function are stored in the storage unit 38.

The display control unit 42 controls the display unit 32 to display the above-mentioned GUI or various information.

The communication control unit 43 has a function of controlling communication operations of the network communication unit 36 and the facsimile communication unit 37.

In the image forming apparatus 10 having such a configuration, the storage unit 38 stores a plurality of files that are print target data including image data and text data. These files are image data showing an image of a document read by the image reading unit 11, image data received by the facsimile communication unit 37, or document data created by an application such as a word processor or spreadsheet software. ..

By the OCR function, the main control unit 41 detects a preset character or character string indicating confidentiality included in the file composed of image data stored in the storage unit 38. Further, the main control unit 41 detects a preset character or character string indicating confidentiality by a known character search function with respect to a file composed of document data stored in the storage unit 38.

Here, the main control unit 41 receives a file list display instruction based on the operation of the touch panel 35 by the user. When the display of the list of files is instructed, the main control unit 41 creates a list of files based on each file stored in the storage unit 38. The display control unit 42 causes the display unit 32 to display the list of the files by, for example, an icon image showing each file. Then, the user performs a touch operation on the touch panel 35 to specify an icon image showing an arbitrary file in the file list on the screen of the display unit 32, and gives an instruction to process the arbitrary file, and the instruction is the main control. When accepted by the unit 41, the main control unit 41 reads the arbitrary file from the storage unit 38, and executes the instructed process for the arbitrary file. For example, when the instruction is a print instruction, the main control unit 41 activates the image forming unit 12 and records the image or text indicated by the data of the arbitrary file on the recording paper. Alternatively, when the instruction is a transmission instruction, the main control unit 41 activates the facsimile communication unit 37 through the communication control unit 43, and causes the file to be transmitted to the communication partner indicated by the instruction.

By the way, there is a highly confidential file among the files stored in the storage unit 38, and the highly confidential file (confidential file) is displayed in the list of files displayed on the display unit 32 by an icon image or the like. When it is displayed on the display unit 32, the existence of the confidential file is known to everyone, which is not preferable for protecting the confidential file.

Therefore, in the image forming apparatus 10 according to the present embodiment, the user can easily set the list display or non-display of each file in the file list, and the confidentiality of the file is enhanced. Further, the image forming apparatus 10 stores the password input by the user in association with the confidential file, and prohibits the contents display, printing, and transmission processing of the confidential file unless the password is input again. It should be noted that the processing of displaying, printing, and transmitting the contents of the confidential file mentioned here is an example of the "processing for opening the file" in the claims.

Next, a processing procedure for displaying or hiding files in the file list and setting a password will be described in detail with reference to the flowchart shown in FIG.

First, at the time of generating a file, the main control unit 41 writes various information about the file in the data table DT illustrated in FIG. The main control unit 41, in this data table DT, as the various information about the file, the file number, the file creation date and time, the file name, the confidentiality of the file, the presence or absence of the file list display (whether to display in the file list) , And password are stored. The data table DT is stored in the storage unit 38.

When a file is generated and stored in the storage unit 38 of the image forming apparatus 10, the user sets a document on the image reading unit 11 and operates the operation unit 34 to input a document reading instruction. When the main control unit 41 receives an instruction to read the original, the main control unit 41 activates the image reading unit 11 in response to the instruction. The image reading unit 11 reads an image of a document and generates image data indicating the image of the document. The main control unit 41 creates a file composed of this image data and stores this file in the storage unit 38 (S101). Alternatively, when the facsimile communication unit 37 receives the image data, the main control unit 41 generates a file including the image data and stores the file in the storage unit 38 (S101). Alternatively, when the communication control unit 43 receives image data or document data from another PC via the network communication unit 36, the main control unit 41 generates a file including the image data or document data, and The file is stored in the storage unit 38 (S101).

At this time, the main control unit 41 writes the file number (identification number unique to the file) and the creation date and time of the file in the data table DT in the storage unit 38 as data related to the file.

In addition, the main control unit 41, for each file stored in the storage unit 38, the file name input by the user's operation of the operation unit 34 or the touch panel 35, in the data table DT in the storage unit 38, for the file. It is written as a part of various information (S102).

Alternatively, since data indicating the sender is added to the data received by the facsimile communication unit 37 or the communication controller 43, the main controller 41 includes the data indicating the sender from the image data. The file name is set as a file name, and this file name is written in the data table DT in the storage unit 38 as a part of various information about the file (S102).

Alternatively, if the user does not input a file name, the main control unit 41 automatically generates a file name based on the creation date and time of the file and the like, and the file name becomes a target in the data table DT in the storage unit 38. It is written as a part of various information about the file (S102).

Subsequently, the main control unit 41 analyzes the data content indicated by the file and determines whether or not the data forming the file includes a preset character or character string indicating confidentiality (S103). .. Alternatively, the main control unit 41 may determine whether or not the file name of the file includes a character or character string indicating the confidentiality (S103). For example, the character or character string indicating confidentiality is “confidential”, “secret”, “confidential”, or the like. The main control unit 41 performs the above determination by character search when the file is document data having text data, and performs OCR processing when the file is image data such as jpeg or PDF. Then, the above determination is performed.

When the main control unit 41 determines that the character or the character string indicating the confidentiality is included (YES in S103), the file is set as the confidential file, and the information indicating the confidentiality is provided to the data table DT in the storage unit 38. Is written as a part of various information about the file (S104).

The user can also operate the operation unit 34 and the touch panel 35 to input a designation as to whether or not the file is confidential. For example, when the designation that the file is confidential is input (YES in S103), the main control unit 41 writes the confidential information in the data table DT in the storage unit 38 by using the file as a confidential file ( S104).

If the main control unit 41 determines in S103 that the data forming the file does not include a preset character or character string indicating confidentiality (NO in S103), the main file is not classified as a confidential file. As a part of various kinds of information about the file, information indicating that there is no confidentiality and that there is display in the file list is displayed in the data table DT in the storage unit 38 as a part of various kinds of information regarding the file as a file list displayed by an icon image. Write (S105). After this, the process ends.

Alternatively, when the user specifies that the file is not confidential by the operation of the operation unit 34 and the touch panel 35 by the user (NO in S103), the main file is not classified as a confidential file and the file is not classified. Information displayed as icon images in the list indicating that there is no confidentiality and that the file list is displayed is written in the data table DT in the storage unit 38 as a part of various kinds of information regarding the file (S105).

After the main control unit 41 writes the confidential information about the file in the data table DT in S104 as described above, the display control unit 42 displays the pop-up screen PU1 as shown in FIG. 5 on the display unit 32. (S106). A password box 51, a confirmation password box 52, a cancel key 53, and an OK key 54 are displayed on the pop-up screen PU1.

Here, the touch operation on the cancel key 53 is performed through the touch panel 35 through the touch panel 35 without the user performing the operation of inputting the password in the password box 51 and the confirmation password box 52 (“not set” in S107). When accepted by the main control unit 41 (“Cancel” in S108), the main control unit 41 erases the file from the storage unit 38 (S115).
After this, the process ends.

In addition, the user performs a touch operation on the OK key 54 through the touch panel 35 without performing the operation of inputting the password into the password box 51 and the confirmation password box 52 (S107 “unset”), and the touch operation is performed. When accepted by the main control unit 41 via the touch panel 35 (“OK” in S108), the display control unit 42 causes the display unit 32 to display the pop-up screen PU2 as shown in FIG. 6 (S110). A message for confirming that the password has not been set, a Yes key 55, and a No key 56 are displayed on the pop-up screen PU2.

Here, for example, when the user touch-operates the Yes key 55, the display control unit 42 accepts the touch operation of the Yes key 55 through the touch panel 35 (YES in S111), and erases the pop-up screen PU2. Then, the main control unit 41 accepts an instruction that the password is not set and the icon image of the file is not displayed in the file list, and information indicating that the file list is not displayed is displayed in the data table DT. It is written as a part of various information (S112). After this, the process ends.

In S111, when the user touches the No key 56 and the display control unit 42 accepts the touch operation of the No key 56 through the touch panel 35 (NO in S111), the display control unit 42 displays the pop-up screen PU2. to erase. After that, the process returns to S106, the display control unit 42 causes the display unit 32 to display the pop-up screen PU1 again (S106), and then the processes of S107 and subsequent steps are performed.

Further, in S107, the user inputs the same password into the password box 51 and the confirmation password box 52, touches the OK key 54 (“setting” in S107), and further, the OK by the user through the touch panel 35. When the main control unit 41 accepts the touch operation of the key 54 (“OK” in S113), the main control unit 41 accepts an instruction to set a password and an instruction not to display the icon image of the file in the file list. In addition to the password, information indicating that the file list is not displayed is written in the data table DT as a part of various information about the file (S114). After this, the process ends.

In S113, when the main control unit 41 accepts the touch operation of the cancel key 53 by the user (“Cancel” in S113), the main control unit 41 displays a password setting instruction and an icon image display in the file list. The instruction to perform is accepted, and in addition to the password, information indicating that the file list is displayed is written in the data table DT as a part of various information regarding the file (S116). After this, the process ends.

As described above, when the file is generated, the storage unit 38 is configured by appropriately setting the file creation date and time, the file name, the confidentiality of the file, the presence or absence of the file list display (the icon image indicating the file is displayed), and the password. It is saved in the data table DT in the. As a result, with respect to a normal file that is not confidential, the password is not set and the file is not classified as a confidential file, and the display indicating the file is set. Further, regarding the confidential file, the setting or non-setting of the password is selected, and then the display indicating the file is not set.

Next, a process of displaying or hiding a file stored in the storage unit 38 in the file list and a process of opening the file based on the data of the file stored in the data table DT will be described. 7A, 7B, 7C, and 7D are flowcharts showing the processing.

First, the display control unit 42 causes the display unit 32 of the image forming apparatus 10 to display, as an initial screen, a plurality of touch keys 61a to 61h associated with respective functions as shown in FIG. At this time, when the user touch-operates the touch key 61h corresponding to the file list, the main control unit 41 receives an instruction to display the file list stored in the storage unit 38 through the touch panel 35.

Subsequently, the main control unit 41 refers to the data table DT in the storage unit 38 to search for a file associated with the information indicating that the file list is displayed, and an icon image indicating each file detected by this search. Is created, and a display screen showing a list of each file associated with the information indicating that the file list is displayed is created using the icon image (S201). The display control unit 42 displays the file list on the display unit 32 (S202). As a result, the user visually recognizes the file list displayed on the display unit 32 to identify each file associated with the information indicating that the file list is displayed, that is, a file that is not a confidential file and a confidential file. However, it is possible to confirm the file list including the files which are said to have the file list display.

FIG. 9 shows an example of a list of files associated with information indicating that a file list is displayed. As shown in FIG. 9, a display screen showing the icon FA of each file associated with the information indicating that the file list is displayed is displayed on the display unit 32 as the file list. A menu key 71, a confidential key 72, a preview key 73, and a print key 74 are displayed on the display screen. Note that, in FIG. 9, for ease of explanation, the icon image FA shows the presence/absence of confidentiality and the presence/absence of file list display. The FA does not display the information.

Here, when the user performs a preset first operation or second operation while the file list shown in FIG. 9 is displayed on the display unit 32, the display control unit 42 displays the information without the file list display. A list of files associated with is displayed on the display unit 32.

When the user wants to display on the display unit 32 a list of files associated with the information without displaying the file list, the user simultaneously touches two places on the screen of the display unit 32 with his finger to The touch operation is continued for a specified time (for example, 2 seconds) or more (this operation is an operation for receiving an instruction to display a list of confidential files that are not displayed on the display unit 32 as a list. This is the first operation. ).

When the main control unit 41 accepts the simultaneous touch operation on the above two places through the touch panel 35 and determines that the touch operation has continued for a predetermined time or longer (YES in S203), the data table DT in the storage unit 38 is stored. By referring to this, a file associated with the information without the file list display is searched and detected, an icon image indicating each detected file is created, and an image indicating a list of each detected file is displayed. Create (S204). The display control unit 42 causes the display unit 32 to display an image showing a list of the respective files (S205). After that, the processing shifts to S218 shown in FIG. 7C or S226 shown in FIG. 7D (each processing after the shift will be described later). As a result, the user can confirm each file stored in the storage unit 38 and whose icon image is not displayed on the display unit 32 by default.

FIG. 10 shows an example of displaying a list of files associated with information without displaying the file list. As shown in FIG. 10, under the control of the display control unit 42, on the display screen of the display unit 32, as a list of files, an icon FA that is an icon image indicating a file associated with information indicating that a file list is displayed. In addition to the above, icons FB and FC indicating files associated with the information without displaying the file list are further displayed. In addition, a menu key 71, a confidential key 72, a preview key 73, and a print key 74 are displayed on the display screen.

As described above, in the present embodiment, first, when the user touches the touch key 61h corresponding to the list of files on the initial screen displayed on the display unit 32, the display unit 32 displays as shown in FIG. A list of files associated with the presence of such a display is displayed.

Then, when the user performs a touch operation on two positions on the display screen of the display unit 32 shown in FIG. 9 at the same time and continues the touch operation for a predetermined time or longer (first operation), As shown in FIG. 10, a list of files associated with the information without the file list display is displayed.

Here, various processes for each file displayed on the display unit 32 will be described.

While the list of files associated with the presence of the display as shown in FIG. 9 is displayed on the display unit 32 (for example, S202 in FIG. 7A), the user can select the icon FA of any file in the list. When the user selects and touches the print key 74, and then touches the print key 74, the main control unit 41 accepts touch operations on the icon FA of the arbitrary file and the print key 74 through the touch panel 35 (S209). An instruction to execute the print process for the file indicated by the icon FA that has been touched is received (S210 “print”). The main control unit 41 reads out the data of the file corresponding to the touch-operated icon FA from the storage unit 38, and causes the image forming unit 12 to record the image or text indicated by the read data on the recording paper ( S211).

When the user selects and touches an icon FA of an arbitrary file in the list shown in FIG. 9, and then touches the preview key 73, the main control unit 41 causes the touch panel 35 to touch the icon of the arbitrary file. Respective touch operations on the FA and the preview key 73 are sequentially accepted (S209), and an instruction to execute a preview process for the file indicated by the icon FA on which the touch operation is performed is accepted (S210 “preview”). Then, the display control unit 42 reads out the data of the file corresponding to the touch-operated icon FA from the storage unit 38. The display control unit 42 causes the display unit 32 to preview-display the image or text indicated by the read data (S212).

At this time, the display control unit 42 causes the display unit 32 to display the image indicating the close key together with the image and the text. When the user touch-operates the close key, the main control unit 41 accepts the touch operation on the close key through the touch panel 35 (YES in S213). Then, the display control unit 42 stops the preview display displayed on the display unit 32 (S214). After that, the process returns to S209.

In addition, the user selects the icon FA of the file with no confidentiality in the list shown in FIG. 9 and performs a touch operation (S209), and then touches the confidential key 72, and the main control unit 41 When the touch operations on the icon FA and the confidential key 72 of an arbitrary file are sequentially received through the touch panel 35 (S210 “Confidential”), the main control unit 41 determines that the arbitrary file touched is a confidential file. Is received, and the information indicating confidentiality is written in the data table DT in the storage unit 38 as a part of various information regarding the file (S215). Subsequently, the display control unit 42 causes the display unit 32 to display the pop-up screen PU1 (FIG. 5) in the same manner as the process of S106 described with reference to FIG. After that, the same processing as S106 to S115 shown in FIG. 3 is performed, and whether or not the file list is displayed and the password are appropriately written in the data table DT in the storage unit 38 (S216). Thereafter, the processing shifts to the processing from S201 shown in FIG. 7A.

When the user touch-operates the menu key 71 without selecting a file, the display control unit 42 accepts the touch operation through the touch panel 35 and displays the list of files displayed at this time (FIG. 9). An instruction to stop the display and display the initial screen (FIG. 8) is accepted (S210 “menu”). Then, the display control unit 42 stops the display of the file list (FIG. 9) and causes the display unit 32 to display the initial screen (FIG. 8) (S217).

Various processes for each file displayed on the display unit 32 will be described subsequently. As shown in FIG. 10, when the list of files associated with the information indicating no file list display is displayed on the display unit 32 based on the user's operation, the user can When the icon FC indicating an arbitrary confidential file for which a password is not set is selected and touch-operated (S218), and then the print key 74 is touch-operated, the main control unit 41 causes the touch panel 35 to touch the icon FC and the icon FC of the arbitrary file.
