Here, since the operator identifier “0004” of the operator C does not match the subject identifier in the history information of FIG. 4 (step S3; NO), in the image forming apparatus 10, the operator identifier “ The target owner identifier in the history information identified as “0004” is compared to determine whether or not they match.
Here, since the operator identifier “0004” of the operator C and the target owner identifier in the history information of FIG. 4 do not match (step S5; NO), the image forming apparatus 10 operates the image forming apparatus 10. Is determined to be “other”.
Since the type of the operator is “other”, the image forming apparatus 10 refers to the “other” row of the determination table. Then, “display” is associated with the “public” column, and “non-display” is associated with the “sensitive” column, the “privacy” column, and the “system” column. Therefore, the image forming apparatus 10 selects the history information with “public” from the history information shown in FIG. 4, and displays the selected history information as shown in FIG. 18 (step S7). ).

[Modification]
As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It can implement with another various form. For example, the present invention may be implemented by modifying the above-described embodiment as follows.

  In the above-described embodiment, the image forming apparatus 10 selects and displays history information according to the type of operator. However, an apparatus that selects and displays history information according to the type of operator. The image forming apparatus 10 is not limited to this. For example, in a system composed of a server device and a client device connected to a computer network, the server device stores a history of processing performed by the server device in response to a request from the client device. The history information may be selected and displayed according to the type.

  The elements stored as the history information are not limited to those shown in FIG. 4 and FIG. 10. For example, information indicating whether or not the processing has been normally executed may be stored as the history information. .

  In the embodiment described above, when display of a list of history information is instructed in the image forming apparatus 10, the image forming apparatus 10 displays all event names of the stored history information regardless of the type of operator. However, the event name to be displayed may be varied depending on the type of the operator. For example, if the operator is an administrator, all event names are displayed. If the operator is a subject, only the event name of the history information that has the same identifier as the operator identifier of the operator in the element of the subject identifier is displayed. May be displayed.

  Specifically, on the screen shown in FIG. 11, the administrator inputs the operator name “administrator” in the text box BX1 for inputting the operator name in the screen of FIG. 11, and the text box BX2 for inputting the password. When the user presses the OK button in the screen after inputting the password “admin”, the person who operates the image forming apparatus 10 is recognized as an administrator in the image forming apparatus 10 and uses the image forming apparatus 10. Is possible. Next, when the administrator operates the operation unit 106 to perform an operation for instructing display of a list of history information stored in the image forming apparatus 10, the image forming apparatus 10 is notified of all events stored as history information. A list of names is displayed as illustrated in FIG.

On the other hand, the operator A whose operator name is “userA” operates the operation unit 106 of the image forming apparatus 10 in a standby state, and enters the operator name in the text box BX1 in the screen of FIG. When the operator name “userA” is input, the password “AAA” is input in the text box BX2 for inputting the password, and then the OK button on the screen is pressed, the operator A uses the image forming apparatus 10 It becomes possible to do. Here, since the operator name is not “administrator”, the image forming apparatus 10 determines that the person who operates the image forming apparatus 10 is not the administrator.
Next, when the operator A operates the operation unit 106 and performs an operation for instructing display of a list of history information stored in the image forming apparatus 10, the operator name “ The image forming apparatus 10 displays only history information including the operator identifier “0002” of “userA”. That is, on the screen of FIG. 13, only the event name “accepting image formation instruction” is displayed, and the other event names “image formation instruction” and “copy” are not displayed.

Also, the operator B whose operator name is “userB” operates the operation unit 106 of the image forming apparatus 10 in the standby state, and enters the operator name in the text box BX1 in the screen of FIG. When the operator name “userB” is input, the password “BBB” is input in the password input text box BX2, and then the OK button on the screen is pressed, the operator B uses the image forming apparatus 10. It becomes possible to do. Here, since the operator name is not “administrator”, the image forming apparatus 10 determines that the person who operates the image forming apparatus 10 is not the administrator.
Next, when the operator B operates the operation unit 106 to perform an operation for instructing display of a list of history information stored in the image forming apparatus 10, the operator name “ The image forming apparatus 10 displays only history information including the operator identifier “0003” of “userB”. In other words, on the screen of FIG. 13, only the event name “Cancel image formation” is displayed, and no other event name “Reception of image formation instruction” or “Copy” is displayed.

The image forming apparatus 10 described above may store the image data of the output image or the image data of the document read by the image reading unit 108 in the storage unit 105 as history information. In this case, the image forming apparatus 10 displays an image of image data stored as history information on the display unit 107 when the operator is an administrator, and displays image data when the operator is not an administrator. The image may not be displayed.
Specifically, on the screen shown in FIG. 11, the administrator inputs the operator name “administrator” in the text box BX1 for inputting the operator name in the screen of FIG. 11, and the text box BX2 for inputting the password. When the user presses the OK button in the screen after inputting the password “admin”, the person who operates the image forming apparatus 10 is recognized as an administrator in the image forming apparatus 10 as described above, and the image forming apparatus 10 can be used.
Next, when the administrator operates the operation unit 106 to perform an operation for instructing display of a list of history information stored in the image forming apparatus 10, as illustrated in FIG. 13, all the history information stored as history information is displayed. A list of event names is displayed. When the administrator selects the displayed “Copy” and presses the “Display” button on the screen, the event name is “Copy” and the occurrence date is “2008/01/02 12:41 : 10 ”and the image read during the copying process are displayed on the display unit 107.

  If the person who has instructed execution of the “copy” process (subject) is “userB”, “0003” is included in the element of the subject identifier in the history information of the “copy” process. Then, the operator A whose operator name is “userA” inputs the operator name “userA” in the text box BX1 for inputting the operator name in the screen of FIG. 11 and the text box BX2 for inputting the password. After the password “AAA” is entered and the image forming apparatus 10 can be used, “copy” is selected from the list of all event names stored as history information shown in FIG. Then, the image forming apparatus 10 displays the contents of the history information. Here, since the identifier “0003” included in the element of the subject identifier in the history information of the “copy” process does not match the operator identifier “0002” of the operator A, the image forming apparatus 10 The image read during the process is not displayed on the display unit 107.

  Further, the operator B whose operator name is “userB” inputs the operator name “userB” in the text box BX1 for inputting the operator name in the screen of FIG. 11, and enters the text box BX2 for inputting the password. After the password “BBB” is entered and the image forming apparatus 10 can be used, when “Copy” is selected from the list of all event names stored as history information shown in FIG. The identifier “0003” included in the element of the subject identifier in the history information of the process of “copying” matches the operator identifier “0003” of the operator B. However, since the operator identified by the operator identifier “0003” is not an administrator, the image forming apparatus 10 does not display the image read during the copying process on the display unit 107.

In addition, when an image indicating confidentiality is included in an image in image data and an image indicating confidentiality is included in an image stored as history information If the image of the image data stored as the history information is not displayed on the display unit 107 and the image indicating the confidentiality image is not included in the image stored as the history information, An image of image data stored as history information may be displayed on the display unit 107.
Further, when image data of a document having an image indicating confidentiality is stored as history information, display and non-display of the image of the image data may be switched according to the type of the operator.
For example, when the operator B whose operator name is “userB” copies a document having an image indicating confidentiality in the image forming apparatus 10, the image data of the document is stored as history information. In this case, in the copy processing history information, the element of the subject identifier includes “0003” that is the operator identifier of “userB”.
If the operator who gives an instruction to display the history of the copying process is an operator who gives an instruction to copy a document having an image showing confidentiality (the person whose operator name is “userB”), the operator Operator identifier “0003” and the operator identifier “0003” included in the element of the subject identifier of the history information match. That is, since the person who instructed the execution of the copying process matches the person who is trying to display the history information, the image forming apparatus 10 displays the image of the image data stored at the time of copying on the display unit 107. .

On the other hand, when the operator who gives an instruction to display the history of the copying process is, for example, the operator A whose operator name is “userA”, the operator identifier of this operator is “0002” and the subject of the history information Does not match the operator identifier “0003” included in the element of the operator identifier. That is, the person who instructed the execution of the copying process does not match the person who is trying to display the history information, and therefore the image forming apparatus 10 does not display the image of the image data stored at the time of copying on the display unit 107. .
In this modification, the administrator may not display the image of the image data of the document having the image indicating the confidentiality.
In this modification, only the operator who gives an instruction to execute the copying process can display image data of a document having an image showing confidentiality. However, the image data of a document having an image showing confidentiality can be displayed. Also, as described in the above-described modification, only the administrator may display, and the operator A and the operator B may not be able to display. That is, a configuration may be adopted in which image data of a document having an image showing confidentiality is not displayed even if a person who has instructed execution of copying processing instructs to display a history.

  The image indicating that the image has confidentiality may be included in the image data by the administrator operating the image forming apparatus 10, or the operator who has instructed the output of the image The forming apparatus 10 may be operated so as to be included in the image data.

  In the image forming apparatus 10, after the operator inputs the operator name and password, an instruction to the image forming apparatus 10 such as a document copying instruction is received, and subsequently an instruction to display history information is received and history information is received. May be displayed.

  Each of the above-described programs includes a magnetic recording medium (magnetic tape, magnetic disk (HDD (Hard Disk Drive), FD (Flexible Disk), etc.)), optical recording medium (optical disk (CD (Compact Disc), DVD (Digital Versatile Disk)). Or the like), and may be provided in a state of being stored in a computer-readable recording medium such as a magneto-optical recording medium or a semiconductor memory and installed in each device.
