Here, the definition information table 102A is shown in FIG. This definition information table 102A is written by definition information storage processing described later, and is divided into three records, an application definition record, an attribute definition record, and a data definition record, and each record is structured hierarchically.
The application definition record specifies an application and a combination of data used in a job of the application. The application is specified by an item called application ID, and the combination of data is specified by an item called job log data item set ID. For example, in the illustrated example, the application ID is “10A” and the job log data item set ID is 10A01. The application definition record includes an uninstall flag. When the application is uninstalled, it can be identified by this flag. Further, even if the same application has a different data item set ID, it becomes a different record.
The attribute definition record is a record that continues to the lower level of the application definition record by the number of data items specified by the job log data item set ID. This attribute definition record includes items of an attribute ID that specifies an attribute of data, an item name that indicates the name of an item, and a data type that indicates the type of data. As a description example of the data type, for example, the description is “numerical type” when the data is represented by a numerical value, and “enumerated type” when the data indicates the content of processing.
In the attribute definition record, data definition records classified into the same data type are arranged in the lower order. The data definition record includes a data ID that specifies the type of data and a data name that indicates the name of the data.
Here, as an example, for example, when the data type is “enumerated type”, the data name has a name such as “full color”, “black and white”, and a data ID for identifying the data. The data definition record is connected to the lower level of the attribute definition record. When the data type is “numeric type”, the data ID of the data definition record becomes unnecessary, and a numerical value is described in the data name. In the example of the attribute definition record shown in FIG. 3, for the application ID “10A”, the attribute ID is 20A, the item name is “color mode”, the data format is “enumeration type”, and the attribute ID is “20A”. It has become. One of the data definition records connected to the attribute definition record has a data name “automatic” and a data ID “30A”.

The printed matter P is output based on the document D. When the multifunction peripheral 100 is operated as a scanner, the control unit 101 operates the image reading unit 103, the image processing unit 105, and the network I / F unit 106 in response to an instruction from the user input from the UI unit 108. The image data of the document D is transmitted to the client terminal 200, for example.
Further, when the multifunction peripheral 100 is operated as a printer, for example, upon receiving an instruction from a client transmitted from the client terminal 200, the control unit 101 performs a network I / F unit 106, an image processing unit 105, and an image forming unit. 104 is operated to output a printed matter P based on the print data transmitted from the client terminal 200. Further, when the MFP 100 is operated as a fax machine, the control unit 101 receives an instruction from the user input from the UI unit 108, and the control unit 101 performs the image reading unit 103, the image processing unit 105, and the network I / F unit 106. To transmit the image data of the document D to another fax machine.

<2. Explanation of job log processing>
Next, operation processing of the multifunction peripheral 100 according to the present embodiment will be described based on the flowcharts of FIGS.

<2-1. Definition information storage processing>
First, the definition information storage process will be described with reference to FIG.
This process is a process executed when a new application is installed in the multifunction peripheral 100. The application can be installed from a storage medium such as a CD-ROM in which a new application is stored via the device I / F unit 107, or from an external server via the network I / F unit 106. In short, it is only necessary that a new application can be installed in the storage unit 102 of the multifunction peripheral 100.

The control unit 101 acquires information for generating each code shown in FIG. 3 from the new application stored in the storage unit 102 (step S1). When each application used in the present embodiment is installed, it passes information constituting the record shown in FIG. 3 to the control unit 101 including the hierarchy of each record. In addition, you may make it obtain each information mentioned above when the control part 101 analyzes an application.
Next, the control unit 101 assigns an application ID and a job log data item set ID to the installed application name, and writes it in the application definition table of the definition information table 102A (step S2). Further, the control unit 101 assigns an attribute ID to the item name / data type, and writes it in the attribute definition record of the definition information table 102A (step S3). Further, the control unit 101 assigns a data ID to the data name and writes it in the data definition table of the definition information table 102A (step S4). As a result, the definition information table 102A as shown in FIG. 3 is completed.
Then, the control unit 101 stores the completed definition information table 102A in the storage unit 102 (step S5).

<2-2. Job log creation processing>
Next, the job log creation process will be described with reference to FIG.
This process is a process of storing, as a job log, the result of the MFP 100 performing any one of “copy”, “fax”, “scanner”, and “printer”.
After the MFP 100 executes any operation, the control unit 101 acquires this operation as job information (step S11).
Since the job information acquired at this time is only the job log record and job log data record shown in FIG. 4, the data amount is small.
The control unit 101 can know the data type by referring to the attribute definition record shown in FIG. 3 from the attribute ID in the job log data record, and obtains the data ID from this data type. At this time, if the data type is “numeric type”, numeric data is obtained instead of the data ID. For example, in the case of a job related to “copy” and “printer”, a job log record having a data type “numerical type” is created for the number of printed materials P output from the image forming unit 104. Is the number of documents D.

The control unit 101 assigns a job ID to the acquired job information, completes the job log record with a date, and stores it in the storage unit 102 (step S12).
By this processing, for example, a job log record and a job log data record corresponding to one job ID are created in the job log table 102B of FIG.

<2-3. Job log output processing>
Next, the job log output process will be described with reference to FIG.
In this process, by operating the UI unit 108 of the multifunction peripheral 100, a list of job logs is output from the image forming unit 104 as a printed matter P, or a job log designated by a request from the external client terminal 200 is output to the client terminal. This is a process of displaying on the 200 display unit. This process is not only executed by a request from the user, but the MFP 100 periodically outputs the printed matter P in the form of a list, transmits it as data to the client terminal 200 of the administrator, There are various modes of output.

In this description, for the sake of convenience, a case where a user selects a job log and requests output will be described.
As a method of selecting a job log, a code string is created from the definition information table 102A using the application name, item name, and data name as search terms for the user, and the job log table 102B is referred to from this code string. A log job can be determined by various methods such as a method for extracting a log job, a method for specifying a period and extracting a log job from this period with reference to the job log table 102B, or a combination of these methods. In the present embodiment, the present invention is not limited to these methods.

The control unit 101 designates a job ID by referring to the job log table 102B from the job log designated by any method (step S21).
The control unit 101 reads and temporarily stores the job log record and job log data record corresponding to the designated job ID (step S22).

  The control unit 101 refers to the definition information table 102A from the job log data item set ID of the read job log record, acquires the application ID, and from the attribute definition record below the job log data item set ID, Reads the same attribute definition record as the attribute ID described in the job log data record. The control unit 101 reads an item name from the read attribute definition record, and temporarily stores the item name in the storage unit 102 (step S23). The control unit 101 refers to the data type described in the attribute definition record read by the above processing. Reads data definition records subordinate to this data type. Of the data definition records read out in this way, the same data ID described in the job log data record is specified, and the data name is read from the data definition record (step S24). On the other hand, when the data type of the identified attribute definition record is a numeric type, the control unit 101 interprets the data ID described in the job log data record as numeric information without referring to the data definition record, This numerical value is added to the item name (step S25).

  Then, the control unit 101 outputs information including the date, application ID, item name, and data name (or numerical value) acquired as described above as a job log (step S26). Since the job log is in a data format, if the job log request is received from the client terminal 200, the control unit 101 transmits the request in this format via the network I / F unit 106 and operates the multifunction peripheral 100. If the request is a job log request, the job log is transferred to the image processing unit 105, converted into image data by the image processing unit 105, and then output as a printed matter P from the image forming unit 104.

  Next, the control unit 101 inquires of the user whether or not to delete the output job log (step S27). Specifically, if the job log is a request from the client terminal 200, this inquiry is transmitted to the client terminal 200. If the job log is a request for operating the multifunction peripheral 100, the inquiry is sent to the UI unit 108. On the display.

If the user selects not to delete in the determination process in step S27 (step S27; NO), the control unit 101 ends this process.
On the other hand, when the user selects to delete in the determination process in step S27 (step S27; YES), the control unit 101 deletes the designated job log, that is, the output job log, from the job log table 102B. (Step S28). Further, the control unit 101 executes processing associated with application deletion (step S29), and ends the job log output processing.
Here, the process accompanying application deletion is a process of deleting a record written in the definition information table 102A after uninstalling the application. If the application is uninstalled and all record portions corresponding to the application written in the definition information table 102A are deleted without performing this process, the job log using this application is displayed when this job log is displayed. Job information corresponding to the application cannot be displayed.

Processing associated with application deletion will be described with reference to FIG.
First, the control unit 101 determines whether or not the uninstall flag in the definition information table 102A illustrated in FIG. 3 is “True” (step S31). This uninstall flag is automatically switched to “True” when the application is uninstalled.

If the uninstall flag is not “True” in the determination process in step S31 (step S31; NO), the control unit 101 ends this process because there is no uninstalled application.
On the other hand, when the uninstall flag is “True” in the determination process of step S31 (step S31; YES), the control unit 101 executes the following process to thereby define the definition information table 102A related to this application. The contents stored in are deleted.

The control unit 101 reads the attribute ID and the data ID from the application ID whose uninstall flag is “True” (step S32). It is assumed that 1 to N attribute IDs and 1 to M data IDs exist for this application ID.
The control unit 101 reads only the data ID from the job log data record of each job log from the job log table 102B (step S33). The control unit 101 collates each data ID of the deleted application ID with each data ID of the job log (step S34), and determines whether there is the same data ID (step S35).
If the same data ID exists in the determination process of step S35 (step S35; YES), the control unit 101 cannot delete the attribute ID located in the upper layer of the data ID, and therefore, the definition information table 102A. The written information is left as it is, and this processing is terminated.

  On the other hand, when the same data ID does not exist in the determination process of step S35 (step S35; NO), the control unit 101 sets the attribute ID positioned higher than the data ID among the deleted applications to this data. The ID is deleted from the registration information table 102A together with the ID (step S36), and this process is terminated.

A specific example of the operation in step S36 will be described with reference to FIG.
The control unit 101 reads the data ID of the application deleted from the definition information table 102A by the process of step S32, and the left frame is formed. At this time, the attribute ID is “N” and the data ID is “M” for the application ID “1”. On the other hand, all data IDs of the job log stored from the job log table 102B are read out by the process of step S33, and the inside of the right frame is formed. Then, the data IDs are collated by the processing of step S34 and step S35 to confirm the presence or absence.

  As a result of this collation, in the case shown in FIG. 11, the data IDs “MA” to “MN” which are lower layers of the attribute ID “NA” do not exist in the job log table 102B, and the definition information table The data IDs “MA” to “MN” and their upper layer attribute ID “NA” are deleted from the record of 102A.

  As described above, in the processing associated with this application deletion, when there is no job log in which each data ID by the deleted application is used in the job log stored in the job log table 102B, The data ID and the attribute ID corresponding to this upper layer are deleted from the definition information table 102A. As a result, definition information that is no longer needed is appropriately deleted to efficiently secure a memory area used for the definition information table 102A.

Furthermore, prior to job log output processing (see FIG. 9), authentication processing and job log output limitation processing may be performed.
In the authentication process, authentication is performed on the registered user table 102C-1 shown in FIG. Specifically, the control unit 101 prompts the user to input a password, and performs authentication by collating the input password with a previously registered password. Thereby, since a job log cannot be acquired by anyone other than a preset user, information leakage can be prevented.
On the other hand, in the job log output limiting process, an attribute ID permitted for the user authority table 102C-2 shown in FIG. 6 is acquired. Specifically, whether or not the permission flag for each attribute ID is “True” is determined in advance for each user ID, and when the permission flag is “True”, output is permitted. As a result, when the job log is output (step S9 in FIG. 9), whether or not the attribute ID in the job flag is permitted is confirmed by the permission flag and output. Thereby, it is possible to set a job log that cannot be acquired by an unauthorized user.

<3. Effects of the embodiment>
As described above, the multifunction peripheral 100 according to the present embodiment has the functions of copy, scanner, printer, and fax, and stores the operation performed using any one of the functions as a job log. This job log includes a hierarchical application ID (application name), attribute ID (item name), and data ID (data name) corresponding to the installed application, and indicates an operation function corresponding to the application. Is constituted by an ID. On the other hand, the storage unit is provided with a definition information table 102A. When a job log is output, the job log that has been decoded by referring back to the definition information table 102A from the specified job log ID and deciphering each name is displayed. Can be provided.
Thus, even for a job performed by an application uninstalled by the user, an accurate job log can be output in a readable manner.

In addition, when the application is uninstalled, the data ID and attribute ID are deleted in the same manner as the process for deleting the application (see FIG. 10), so that the registration information that is no longer necessary for job log output. Can be deleted as appropriate, and the storage area can be activated.
In addition, even if the attribute ID and data ID correspond to the lower layer of the deleted application, if the deleted application data ID remains in the job log table 102B, these processes are not performed. As a result, even if the job log is for a job using the deleted application, the job log information can be output accurately. Thereby, the user can easily grasp the job of the multifunction peripheral 100 from the job log.

<4. Modification>
