Description

  The present invention relates to an image forming apparatus, an event notification method, and a program, and more particularly to an image forming apparatus, an event notification method, and a program for notifying a computer via a network of an event related to a distribution job.

  Conventionally, there is a distribution system in which image data scanned by an image forming apparatus having a scanner is transferred to a distribution server, and the distribution server executes distribution of the image data to a set distribution destination.

  By controlling the distribution process by the distribution server, it is possible to reduce the load on the image forming apparatus having a scarce hardware resource. As a result, the hardware resources of the image forming apparatus can be directed to original functions (printing, scanning, copying, etc.).

By the way, in a computer system, a log is generally recorded for various purposes such as failure analysis, charging information recording, or security ensuring. Similarly, the distribution system needs to record a log relating to a distribution job. From the viewpoint of suppressing the consumption of hardware resources of the image forming apparatus, it is desirable that the log recording destination of the distribution job is a computer other than the image forming apparatus (hereinafter referred to as “log recording apparatus”). In this case, the image forming apparatus needs to notify the log recording apparatus of various events that occur regarding the distribution job. This is because the log recording apparatus can record a log by an event notified from the image forming apparatus.
JP 2008-97586 A

  However, when cancellation of a delivery job is possible, if an event notification is not properly performed from the image forming apparatus to the log recording apparatus, a log that is redundant or difficult to analyze is recorded, or the network load May be raised unnecessarily.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus, an event notification method, and a program that can appropriately notify an event related to a distribution job.

In order to solve the above problems, the present invention provides a reading unit that reads image data from a document, a distribution request unit that transmits a distribution job execution request regarding the read image data to a distribution device via a network, and the distribution depending on the job cancellation request, the the job management means for executing the cancellation of the distribution job distribution apparatus, when a successful cancel of the prior Symbol delivery job, shown to jobs that delivery job by canceling is completed When the completion event is sent to the log recording device and the cancellation fails because the distribution job to be canceled has already been completed, it indicates the job status event indicating that the cancellation has failed and the completion of the distribution job. Event transmission means for transmitting the job completion event to the log recording device. .

  In such an image forming apparatus, an event related to a distribution job can be notified appropriately.

  According to the present invention, it is possible to appropriately notify an event related to a distribution job.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a distribution system according to the first embodiment. In FIG. 1, a distribution system 1 includes an image forming apparatus 10, a distribution server 20, a management terminal 30, a directory server 40, and the like.

  The image forming apparatus 10 receives an input of a delivery job execution instruction. In the present embodiment, the distribution job refers to a series of processes until the distribution server 20 distributes image data scanned by the image forming apparatus 10. The distribution server 20 is a computer that executes distribution processing of image data read by the image forming apparatus 10. In the drawing, a Web server 51, a file sharing server 52, and a mail server 53 are illustrated as distribution destinations of image data in a distribution job.

  The management terminal 30 is a computer such as a PC (Personal Computer) used by the administrator of the distribution system 1. The administrator sets setting information related to scanning and distribution (hereinafter referred to as “distribution setting information”) for each user or group via the management terminal 30. That is, the setting information for the distribution job is not set by each user when the job is executed, but is set in advance by the administrator. In addition, the administrator operates the distribution job stored in the distribution server 20 via the management terminal 30 (for example, cancels the distribution job).

  The directory server 40 is a computer having an authentication function for a user who uses the distribution system 1 and a management function for distribution setting information.

  The image forming apparatus 10 can communicate with the distribution server 20, the management terminal 30, and the directory server 40. The management terminal 30 can communicate with the directory server 40. However, all the devices shown in FIG. 1 may be able to communicate with each other. Here, “communicable” means being connected via a network such as a LAN (Local Area Network) or being communicable via a wireless LAN (Local Area Network).

  FIG. 2 is a diagram illustrating a functional configuration example of the distribution system according to the first embodiment. Each unit in the figure is realized by a process that a program installed in each device causes a CPU of each device to execute.

  The management terminal 30 includes a distribution setting reception unit 31, a job operation unit 32, a log recording unit 33, and the like.

  The distribution setting reception unit 31 receives an input of distribution setting information for each user or group from an administrator, and registers the distribution setting information in the directory server 40. The distribution setting information includes setting information (scanning conditions) regarding scanning of image data to be distributed and setting information (distributing conditions) regarding distribution. The setting information related to scanning includes, for example, reading resolution and color mode. Further, the setting information related to distribution includes information regarding a distribution method (email or file transfer, etc.) and a distribution destination. The distribution setting reception unit 31 also causes the image forming apparatus 10 to verify the validity of the distribution setting information before registering the input distribution setting information in the directory server 40.

  The job operation unit 32 receives an operation request for a distribution job being executed or accumulated in the distribution server 20 from an administrator, and transmits the operation request to the image forming apparatus 10. In this embodiment, a delivery job cancel request is input as an operation request. The log recording unit 33 receives an event that has occurred regarding a distribution job from the image forming apparatus 10 and records a log regarding the distribution job in the storage device of the management terminal 30.

  The image forming apparatus 10 includes a distribution setting verification unit 121, an authentication control unit 122, a distribution control unit 123, a scanner control unit 124, a job management unit 125, an unauthorized request detection unit 126, an event notification unit 127, and the like.

  The distribution setting verification unit 121 verifies the validity of the distribution setting information in response to a request from the distribution setting reception unit 31 of the management terminal 30. The validity of the distribution setting information refers to whether or not the image forming apparatus 10 can cope with the setting information related to the scan included in the distribution setting information (whether or not the image forming apparatus 10 has a corresponding capability). For example, when full-color reading is set in the distribution setting information, if the image forming apparatus 10 can handle only monochrome reading, it is determined that the distribution setting information is not valid.

  The authentication control unit 122 controls user authentication processing of the image forming apparatus 10. Actual authentication processing is delegated to the directory server 40. Only the authenticated user can cause the image forming apparatus 10 to execute scanning for distribution. The distribution control unit 123 controls the execution of the pre-processing of the distribution job (processing of scanning image data to be distributed according to the distribution setting information and transmitting a distribution request for the scanned image data to the distribution server 20). The scanner control unit 124 controls a scanner provided in the image forming apparatus 10 and reads image data from a document.

  The job management unit 125 executes processing corresponding to a distribution job operation request from the job operation unit 32 of the management terminal 30. The unauthorized request detection unit 126 detects an operation request for a distribution job from an unauthorized terminal. In the present embodiment, an operation request for a distribution job can be accepted only from the operation panel of the image forming apparatus 10 or the management terminal 30. In other words, only the user and the administrator who input the image data distribution instruction to the image forming apparatus 10 are permitted to operate the distribution job. Therefore, the fraud request detection unit 126 determines that an operation request from a network other than the management terminal 30 via the network is an operation request from an unauthorized terminal. In the present embodiment, a delivery job cancel request is employed as an example of the operation request.

  The event notification unit 127 notifies an event related to the distribution job to the log recording unit 33 of the management terminal 30.

  The directory server 40 includes a distribution setting management unit 41, an authentication processing unit 42, a user DB 43, and the like. The distribution setting management unit 41 registers the distribution setting information transferred from the distribution setting receiving unit 31 of the management terminal 30 in the user DB 43. The distribution management unit 41 also transmits distribution setting information registered in the user DB 43 to the distribution control unit 123 in response to a request from the distribution control unit 123 of the image forming apparatus 10. In response to a request from the authentication control unit 123 of the image forming apparatus 10, the authentication processing unit 42 authenticates the user of the image forming apparatus 10 using authentication information (for example, a user name and password) registered in the user DB 43. . The user DB 43 is a database that stores authentication setting information for each user or group and stores authentication information for each user.

  The distribution server 20 includes a distribution job receiving unit 21 and a distribution job processing unit 22. The distribution job receiving unit 21 receives a distribution job from the distribution control unit 123 of the image forming apparatus 10. The distribution job processing unit 22 executes subsequent processing (processing for distributing image data to a destination set in the distribution setting information) for the distribution job received by the distribution job receiving unit 21.

  FIG. 3 is a diagram illustrating a hardware configuration example of the image forming apparatus according to the embodiment of the present invention. 3, the image forming apparatus 10 includes hardware such as a controller 11, a scanner 12, a printer 13, a modem 14, an operation panel 15, a network interface 16, and an SD card slot 17.

  The controller 11 includes a CPU 111, a RAM 112, a ROM 113, an HDD 114, and the like. The ROM 113 stores various programs and data used by the programs. The RAM 112 is used as a storage area for loading a program, a work area for the loaded program, and the like. The CPU 111 realizes various functions by processing a program loaded in the RAM 112. The HDD 114 records programs and various data used by the programs.

  The scanner 12 is hardware for reading image data from a document. The printer 13 is hardware for printing image data on printing paper. The modem 14 is hardware for connecting to a telephone line, and is used to execute transmission / reception of image data by FAX communication. The operation panel 15 is hardware including input means such as buttons for accepting input from a user and display means such as a liquid crystal panel. The network interface 16 is hardware for connecting to a network such as a LAN (whether wired or wireless). The SD card slot 17 is used for reading a program recorded on the SD card 80. That is, in the image forming apparatus 10, not only the program recorded in the ROM 113 but also the program recorded in the SD card 80 can be loaded into the RAM 112 and executed.

  Note that the image forming apparatus 10 does not have to include the printer 13 and the modem 14 in implementing this embodiment.

  Hereinafter, the processing procedure of the distribution system 1 will be described. FIG. 4 is a sequence diagram for explaining the distribution setting information registration process.

  In step S101, the distribution setting reception unit 31 of the management terminal 30 receives an input of distribution setting information from the administrator. The distribution setting information is input, for example, via a distribution setting screen that the distribution setting receiving unit 31 displays on the display device of the management terminal 30. On the distribution setting screen, it is possible to input distribution setting information (such as setting information regarding scanning and setting information regarding distribution) for each user or group. Therefore, the administrator inputs distribution setting information for each user or group in consideration of a scanning method or a distribution destination that can be permitted for the user or group. Note that distribution setting information may be input to a plurality of users or groups in a single input operation. Also, a plurality of distribution setting information may be input for one user or one group. Each distribution setting information is also set with a name (setting name) for identifying each setting content.

  Subsequently, the distribution setting reception unit 31 transmits the input distribution setting information to the distribution setting verification unit 121 of the image forming apparatus 10 and requests verification of the validity of the distribution setting information (S102). In response to receiving the validity verification request, the distribution setting verification unit 121 records the IP address of the transmission source of the verification request in the HDD 114 as identification information of the management terminal 30 (S103). Note that the IP address of the source of the verification request is included in the message indicating the verification request.

  Subsequently, the distribution setting verification unit 121 compares the capability information related to scanning of the image forming apparatus 10 with the setting information related to scanning included in the distribution setting information, and verifies the validity of the distribution setting information (S104). Here, the capability information is, for example, list information of setting items that can be set for a scan job executed by the image forming apparatus 10, and is stored in the HDD 114 of the image forming apparatus 10. Therefore, the delivery setting verification unit 121 determines that the delivery setting information is not valid when the setting items not included in the capability information are included in the delivery setting information. On the other hand, the delivery setting verification unit 121 determines that the delivery setting information is valid when all the setting information items related to the scan included in the delivery setting information are included in the capability information. Subsequently, the distribution setting verification unit 121 returns a verification result to the distribution setting reception unit 31 (S105). Subsequently, the distribution setting reception unit 31 transmits the distribution setting information determined to be appropriate to the distribution setting management unit 41 of the directory server 40, and requests registration of the distribution setting information (S106). The distribution setting management unit 41 registers the received distribution setting information in the user DB 43 in association with the setting target user or group.

  Next, FIG. 5 is a sequence diagram for explaining the processing procedure of the distribution job. In FIG. 5, an operation is performed on the image forming apparatus 10 by a certain user (including general users other than the administrator).

  When a distribution job start instruction is input by the user via the operation panel 15 of the image forming apparatus 10, the authentication control unit 122 causes the operation panel 15 to display a login screen. The user inputs his / her authentication information (user name and password) via the login screen (S111). The authentication control unit 122 causes the authentication processing unit 42 of the directory server 40 to perform authentication based on the input authentication information (S112). More specifically, the authentication control unit 122 transfers the input authentication information to the authentication processing unit 42. The authentication processing unit 42 compares the authentication information with the authentication information registered in the user DB 43 to authenticate the user. The authentication processing unit 42 returns the authentication result to the authentication control unit 122.

  When the authentication is successful, the distribution control unit 123 acquires distribution setting information registered for the authenticated user (hereinafter referred to as “login user”) from the distribution setting management unit 41 of the directory server 40 (S113). ). More specifically, the distribution control unit 123 transmits a distribution setting information acquisition request to the distribution setting management unit 41 by designating the user name of the login user. The distribution setting management unit 41 acquires distribution setting information registered for the user name from the user DB 43. Here, a plurality of pieces of distribution setting information can be acquired. The distribution setting management unit 41 returns the acquired user setting information to the distribution control unit 123.

  Subsequently, the distribution control unit 123 displays a list of received distribution setting information (that is, a list of distribution setting information set by the administrator for the login user) on the operation panel 15 (S114). For example, a list of setting names of distribution setting information is displayed. Each distribution setting information included in the list has different setting contents (for example, a scanning method and a distribution method). Therefore, the user selects distribution setting information corresponding to a desired scanning method and distribution method from the list (S115). The distribution control unit 123 records the selected distribution setting information in the RAM 112 as an execution target. Subsequently, when the user sets a document to be distributed on the scanner 12 and presses an execution button (start key) on the operation panel 15 (S117), the distribution control unit 123 starts a distribution job. When starting a distribution job, the distribution control unit 123 assigns a unique ID (job ID) to each distribution job to the distribution job to be started, and generates an entry corresponding to the job ID in the job management table.

  FIG. 6 is a diagram illustrating a configuration example of the job management table. In the figure, a job management table 128 is a table for managing the setting name and status for each job ID. The setting name is a setting name of distribution setting information used in the distribution job related to the job ID. The status is information indicating the status of the distribution job, and “start” is registered at the start. FIG. 6 shows a state in which an entry for the distribution job with the job ID “002” is added.

  Subsequently, the distribution control unit 123 requests the event notification unit 127 to transmit a job status event to the management terminal 30. The event notification unit 127 transmits a job status event to the log recording unit 33 of the management terminal 30 (S118). The job status event is an event other than the completion or end of the distribution job, and is notification information for notifying various events that occur regarding the distribution job (for example, a change in the status of the distribution job). In the present embodiment, the job status event is used to notify the start of the job, the job cancellation failure, and the detection of an illegal job cancellation. In step S118, a job status event indicating the start of the job is transmitted. That is, the job status event transmitted in step S118 includes the job ID of the started distribution job and an identifier indicating the start of the job as attribute information. Note that the identification information (IP address) of the management terminal 30 is recorded in the HDD 114 of the image forming apparatus 10 by the distribution setting verification unit 121. The event notification unit 127 determines an event transmission destination based on the identification information.

  The log recording unit 33 that has received the job status event records a log related to the distribution job in the storage device of the management terminal 30 based on the attribute information of the job status event.

  Subsequently, the distribution control unit 123 inputs a scan execution instruction to the scanner control unit 124. In response to the execution instruction, the scanner control unit 124 controls the scanner 12 and executes reading (scanning) of image data from the document (S119). At this time, the scanner control unit 124 executes the scan according to the setting information regarding the scan included in the distribution setting information recorded in the RAM 112 as an execution target. The scanner control unit 124 records the read image data in the RAM 112 or the HDD 114.

  When the scan of the image data is completed, the distribution control unit 123 sends the image data recorded in the RAM 112 or the HDD 114, the distribution setting information to be executed, and the job ID to the distribution job receiving unit 21 of the distribution server 20. Transmit and request execution of distribution processing (S120). After transmitting the request to the distribution server 20, the distribution control unit 123 updates the status of the job ID in the job management table 128 to “processing”.

  Subsequently, the distribution job receiving unit 21 registers the received job ID in the job queue, and stores the received image data and distribution setting information in the storage device of the distribution server 20 in association with the job ID. The job queue is a storage area in which job IDs are recorded according to the job execution order.

  Subsequently, the distribution job processing unit 22 sequentially processes the distribution jobs based on the job ID registered in the job queue. Specifically, the distribution job processing unit 22 extracts one job ID from the job queue, and is set in the setting information regarding distribution included in the distribution setting information stored in association with the job ID. The image data stored in association with the job ID is distributed to a distribution destination (for example, the Web server 51, the file sharing server 52, or the mail server 53) (S121). For example, the image data distributed to the web server 51 is published on the web by the web server 51. The image data distributed to the file sharing server 52 is stored in a folder that is a storage destination. The folder name of the storage destination is included as information constituting the distribution destination in the distribution setting information. The image data distributed to the mail server 53 is transmitted by mail. The mail address of the transmission destination is included as information constituting the distribution destination in the distribution setting information.

  When the distribution process is normally completed, the distribution job processing unit 22 notifies the distribution control unit 123 of the image forming apparatus 10 of the completion (normal end) of the distribution process together with the job ID (S122). In response to the notification, the distribution control unit 123 updates the status corresponding to the job ID in the job management table 128 to “completed”. Alternatively, the entry related to the job ID may be deleted from the job management table 128. In addition, the distribution control unit 123 requests the event notification unit 127 to transmit a job completion event to the management terminal 30. The event notification unit 127 transmits a job completion event to the log recording unit 33 of the management terminal 30 (S123). The job completion event is notification information for notifying completion or end of a distribution job. All distribution jobs are always completed or completed. Therefore, the job completion event is always issued once for all distribution jobs (unless a communication abnormality or the like occurs). The job completion or termination includes job completion due to normal termination, job termination due to interruption, or job termination due to cancellation. The job completion event includes an identifier for identifying normal end, interruption, and cancellation and a job ID as attribute information. Here, since the distribution job is normally completed, the event notification unit 127 transmits a job completion event indicating normal termination to the log recording unit 33.

  The log recording unit 33 that has received the job completion event records a log related to the distribution job in the storage device of the management terminal 30 based on the attribute information of the job status event.

  The completion of the distribution job can be regarded as a change in the state of the distribution job. Therefore, it can be considered that a job status event is also transmitted to the management terminal 30 in response to the normal end of the distribution job. However, in this embodiment, when the distribution job ends normally, the event notification unit 127 does not transmit a job status event. This is because even if a job status event indicating that the distribution job has been normally completed is notified, the content is included in the job completion event, and substantially the same content is notified redundantly. By not transmitting a job status event indicating normal termination, redundant event transmission is avoided. In addition, it is avoided that the log indicating that the distribution job is normally completed is recorded in the management terminal 30 in duplicate.

  Next, cancellation of a distribution job from the management terminal 30 will be described. FIG. 7 is a sequence diagram for explaining the processing procedure of the delivery job cancel processing from the management terminal. In the figure, an operation is performed by the administrator at the management terminal 30.

  For example, when the administrator inputs a job list display instruction via the job operation screen displayed on the display device of the management terminal 30 by the job operation unit 32 (S131), the job operation unit 32 displays the distribution job list. An information acquisition request is transmitted to the job management unit 125 of the image forming apparatus 10 (S132). The job management unit 125 returns the distribution job list information registered in the job management table 128 to the job operation unit 32 (S133). The job operation unit 32 displays a list of received distribution jobs (job list) on the job operation screen (S134). In the job list, for example, a distribution job setting name and a list of statuses are displayed.

  Subsequently, when an administrator selects an arbitrary distribution job from the job list and clicks a cancel button on the job operation screen (S135), the job operation unit 32 specifies a job ID of the selected distribution job. Then, a cancellation request for the distribution job is transmitted to the job management unit 125 (S136). Note that the distribution job that can be selected as a cancellation target in step S135 is a distribution job whose status is “start” or “processing”.

  When the job management unit 125 receives the cancellation request for the distribution job, the job management unit 125 requests the fraud request detection unit 126 to confirm the validity of the cancellation request. The fraud request detection unit 126 records the IP address of the cancellation request source (the IP address included in the cancellation request) on the HDD 114 as the identification information of the management terminal 30 (that is, the identification information of the device permitted to cancel). The validity of the cancel request is confirmed (S137). The fraud request detection unit 126 determines that the cancel request is illegal when the two do not match, and determines that the cancel request is valid when the two match. Here, since the management terminal 30 is the transmission source of the cancellation request, it is determined that the cancellation request is valid.

  When the validity of the cancel request is confirmed, the job management unit 125 designates the job ID to be canceled and transmits a distribution job cancel request to the distribution job receiving unit 21 of the distribution server 20 (S138). Note that the job management unit 125 updates the status of the job ID in the job management table 128 to “Canceled” before or after transmission of the cancel request.

  The distribution job receiving unit 21 deletes the job ID specified in the cancel request from the job queue, and deletes the image data and distribution setting information associated with the job ID from the storage device of the distribution server 20 (S139). As a result, the distribution job is canceled. If the cancellation is successful, the distribution job receiving unit 21 returns information indicating the success of the cancellation to the job management unit 125 together with the job ID (S140).

  When the job management unit 125 receives information indicating successful cancellation, the job management unit 125 updates the status of the job ID in the job management table 128 to “cancelled”. Subsequently, the job management unit 125 requests the event notification unit 127 to notify the job completion event. The event notification unit 127 transmits a job completion event including, as attribute information, a job ID and an identifier indicating completion due to cancellation to the log recording unit 33 of the management terminal 30 (S141).

  The log recording unit 33 that has received the job completion event records a log related to the distribution job in the storage device of the management terminal 30 based on the attribute information of the job status event.

  Note that even when the cancellation is successful and the distribution job is terminated by the cancellation, the job status event is not transmitted. The reason is the same as when the distribution job is normally completed.

  Next, FIG. 8 is a sequence diagram for explaining a processing procedure when a cancellation is instructed for a completed distribution job. In FIG. 8, the same steps as those in FIG. 7 are denoted by the same step numbers, and the description thereof is omitted as appropriate.

  In FIG. 8, for example, the distribution server 20 executes a distribution process related to a distribution job to be canceled while a cancel instruction is being given in the job list (S151). Subsequently, the distribution completion is notified to the distribution control unit 123 of the image forming apparatus 10 together with the job ID (S152). In response to the notification, the distribution control unit 123 changes the status corresponding to the job ID in the job management table 128 to “completed”.

  Thereafter, a cancel request for the job ID is transmitted from the job operation unit 32 of the management terminal 30 to the job management unit 125 of the image forming apparatus 10 (S136). Here, the status of the designated job ID is “completed” and cannot be canceled. Therefore, the job management unit 125 requests the event notification unit 127 to transmit a job status event for notifying the cancellation failure. In response to the request, the event notification unit 127 transmits a job status event including a job ID and an identifier indicating a cancellation failure as attribute information to the log recording unit 33 of the management terminal 30 (S153). Also, in response to the distribution job completion notification (S152) from the distribution job processing unit 22, the distribution control unit 123 requests the event notification unit 127 to transmit a job completion event indicating the normal end of the distribution job. In response to the request, the event notification unit 127 transmits a job completion event including the job ID and the identifier indicating the normal end of the distribution job as attribute information to the log recording unit 33 of the management terminal 30 (S154).

  The log recording unit 33 of the management terminal 30 records a log relating to the distribution job based on the job status event or the attribute information of the job completion event at the timing (S153, S154) when each job status event and job completion event is received. Record in the storage device of the management terminal 30.

  Here, the job status event is also notified because it is not appropriate to notify the cancellation failure in the job completion event. That is, the job completion event is notified in response to the completion or completion of the distribution job. However, when the cancellation fails, the distribution job may be still being processed or may have already been completed or completed. This is because a completion event cannot be issued. Therefore, in this embodiment, the cancellation failure is notified by a job status event.

  On the other hand, the timing of the successful cancellation and the end of the distribution job coincide. Therefore, when the cancellation is successful, only the job completion event indicating the successful cancellation is issued as described in FIG.

  Note that the context of the job status event in step S153 and the job completion event in step S154 can change depending on the timing. For example, a job status event may be notified after a job completion event is notified first.

  Next, FIG. 9 is a sequence diagram for explaining a processing procedure when a cancel instruction from the operation panel and a cancel instruction from the management terminal overlap.

  For example, when the user selects a delivery job to be canceled on the job list screen displayed on the operation panel 15 of the image forming apparatus 10 by the job management unit 125 and inputs a cancel instruction (S161), the job management unit 125 designates the job ID of the distribution job to be canceled, and transmits a distribution job cancel request to the distribution job receiving unit 21 of the distribution server 20 (S162). The job management unit 125 updates the status of the job ID in the job management table 128 to “Canceled” before or after transmitting the cancel request. In the job list screen, a list of distribution jobs whose job IDs are registered in the job management table 128 is displayed.

  Subsequently (for example, immediately after step S161), the job management unit 125 receives a cancel request for the same distribution job as the distribution job instructed to be canceled from the operation panel 15 from the job operation unit 32 of the management terminal 30. (S163). Step S163 corresponds to step S136 in FIG. In this case, based on the job management table 128, the job management unit 125 recognizes that the distribution job is being canceled (that is, already requested to be canceled), and does not make a cancellation request to the distribution server 20 again. . By the way, in this case, it can be considered that the cancellation request from the management terminal 30 has failed. However, the job management unit 125 does not request the event notification unit 127 to transmit a job status event indicating a cancellation failure.

  Subsequently, the job management unit 125 receives information indicating successful cancellation from the distribution job reception unit 21 of the distribution server 20 (S164). Subsequently, the job management unit 125 updates the status of the distribution job to be canceled to “cancelled” in the job management table 128. Subsequently, the job management unit 125 requests the event notification unit 127 to transmit a job completion event indicating completion due to cancellation. The event notification unit 127 transmits a job completion event including, as attribute information, a job ID and an identifier indicating completion due to cancellation to the log recording unit 33 of the management terminal 30 (S165).

  That is, strictly speaking, the processing for the cancel request from the management terminal 30 has failed, but the cancellation of the distribution job itself has succeeded. Therefore, the image forming apparatus 10 transmits only the job completion event indicating the successful cancellation to the management terminal 30 without transmitting the job status event indicating the cancellation failure to the management terminal 30. If a job status event indicating a cancellation failure is transmitted to the management terminal 30, a log indicating the cancellation failure is recorded based on the job status event, and a delivery due to a successful cancellation based on the subsequent job completion event is recorded. A log indicating the end of the job is recorded. In this case, a log that is very difficult to understand at a glance whether the cancellation has failed or succeeded is recorded. In addition, since the delivery job is substantially canceled, it is considered appropriate to notify the management terminal 30 of the successful cancellation. Therefore, in the present embodiment, when the distribution job has already been canceled due to the overlapping cancel instruction, the management terminal 30 is notified of only the job completion event indicating the end due to the cancellation.

  Next, FIG. 10 is a sequence diagram for explaining a processing procedure when a delivery job cancellation is requested from a terminal other than the management terminal. In the figure, a terminal 60 is a computer different from the management terminal 30.

  In step S <b> 201, the job management unit 125 of the image forming apparatus 10 receives from the terminal 60 a cancel request for a job in which a job ID that actually exists is specified. Subsequently, the job management unit 125 requests the fraud request detection unit 126 to confirm the validity of the cancellation request. The fraud request detection unit 126 compares the IP address of the cancellation request source (the IP address included in the cancellation request) with the IP address recorded in the HDD 114 as the identification information of the management terminal 30, and the validity of the cancellation request Is confirmed (S137). Here, since the terminal 60 other than the management terminal 30 is the source of the cancel request, it is determined that the cancel request is illegal.

  In response to the determination result indicating that the cancel request is invalid, the job management unit 125 requests the event notification unit 127 to transmit a job status event indicating that there is an invalid cancel request. The event notification unit 127 transmits, to the log recording unit 33 of the management terminal 30, a job status event that includes, as attribute information, a job ID that is a cancel target and an identifier that indicates that there has been an illegal cancel request (S203). .

  The log recording unit 33 that has received the job status event records in the storage device of the management terminal 30 a log indicating that there has been an invalid cancel request based on the attribute information of the job status event.

  As described above, since the image forming apparatus 10 holds the identification information of the management terminal 30 in advance, it can appropriately determine whether or not the cancel request source is the management terminal 30. Therefore, it is possible to appropriately detect a cancel request from other than the management terminal 30. In addition, since the job status event indicating that there has been an unauthorized cancel request is notified to the management terminal 30, it is possible to appropriately record in the log that there has been an unauthorized cancel request at the management terminal 30. As a result, the administrator who refers to the log can confirm the fact that there was unauthorized access. Note that identification information (for example, an IP address, etc.) of the request source of an unauthorized cancellation request may be included in the attribute information of the job status event. In this case, by recording the identification information in the log, it is expected that the burden on the follow-up investigation of the unauthorized cancellation request source by the administrator is reduced.

  By the way, when the user of the terminal 60 is malicious, it is conceivable that a job cancel request is repeatedly made while changing the job ID. If a job status event is issued for all invalid cancellation requests, the network load increases, and the log recording area in the management terminal 30 becomes a log full state (a state where there is no free space) in a short period of time. It is possible. An example of preventing such inconvenience will be described.

  FIG. 11 is a sequence diagram for explaining the processing procedure of the first countermeasure processing for repeated invalid cancellation requests. In the figure, a terminal 60 is a terminal that repeatedly transmits unauthorized cancellation requests.

  In step S201, the job management unit 125 of the image forming apparatus 10 receives a job cancel request from the terminal 60 (S211). The job ID specified in the job cancel request may exist or may not exist. Subsequently, the job management unit 125 requests the fraud request detection unit 126 to confirm the validity of the cancellation request. The job management unit 125 detects that the terminal 60 other than the management terminal 30 is the source of the cancel request, and determines that the cancel request is invalid (S212). If it is determined that the cancellation request is illegal, the unauthorized request detection unit 126 uses the identification information (for example, IP address) of the cancellation request source and the current time (that is, the time when the unauthorized cancellation request is received). The identification information of the unauthorized terminal is recorded in the HDD 114 (S213).

  In response to the determination result indicating that the cancel request is invalid, the job management unit 125 requests the event notification unit 127 to transmit a job status event indicating that there is an invalid cancel request. The event notification unit 127 transmits a job status event including, as attribute information, the job ID to be canceled and an identifier indicating that there has been an illegal cancellation request, to the log recording unit 33 of the management terminal 30 (S214). .

  Thereafter, the job management unit 125 receives a job cancel request repeatedly from the terminal 60 (S215, S217, S219). Each time a cancel request is received, the fraud request detection unit 126 checks the validity of the cancel request (whether the cancel request source is the management terminal 30), and the IP address of the cancel request source identifies the fraudulent terminal. It is determined whether the information matches the identification information recorded in the HDD 114 (S216, S218, S220).

  If it is determined that the IP address of the cancellation request source matches the identification information of the unauthorized terminal, and if it is within a predetermined time from the time when the identification information of the unauthorized terminal is recorded, the job management unit 125 The event notification unit 127 is not requested to transmit a job status event indicating that there has been a cancel request.

  According to the processing in FIG. 11, the number of job status event transmissions based on unauthorized cancellation requests repeatedly performed from the same terminal can be minimized. As a result, it is possible to prevent the network load from becoming abnormally high. In addition, the log storage area in the management terminal 30 can be prevented from being unnecessarily compressed.

  FIG. 12 is a sequence diagram for explaining a processing procedure of a second countermeasure process for an illegal cancellation request that is repeatedly performed. In FIG. 12, the same steps as those in FIG. 11 are denoted by the same step numbers, and the description thereof is omitted.

  FIG. 12 is different from FIG. 11 in that transmission of a job status event in response to an illegal cancel request from the same terminal 60 is performed not at regular intervals but at regular intervals. Accordingly, in FIG. 12, the fraud request detection unit 126 updates the number of fraudulent cancel requests each time an fraud cancel request from the terminal 60 is detected. When the number of times exceeds the predetermined number, the event notification unit 127 transmits a job status event indicating that there has been an unauthorized cancellation request to the log recording unit 33 of the management terminal 30 again.

  The same effects as in FIG. 11 can be obtained by the processing procedure of FIG.

  As described above, according to the first embodiment, by appropriately controlling the notification timing of two types of events such as a job completion event and a job status event, an increase in network load and a recorded log can be recorded. It is possible to effectively prevent redundancy or difficulty in analysis.

  By the way, in the first embodiment, the subsequent processing (distribution processing) of the distribution job is performed by a predetermined distribution server 20. However, a PC (Personal Computer) (hereinafter referred to as “user PC”) used by each user may function as the distribution server 20. A second embodiment is shown as an example in which a user PC functions as the distribution server 20.

  FIG. 13 is a diagram illustrating a configuration example of a distribution system according to the second embodiment. In the distribution system 2 in the figure, the image forming apparatus 510, the user PC 520, and the network application management server 530 are connected by a network (regardless of wired or wireless) such as a LAN (Local Area Network).

  The user PC 520 has an application (hereinafter referred to as “net application”) that can be used via the network from the image forming apparatus 510 or the user PC. The net application can be placed on any computer on the network. Therefore, the network application can be arranged also in other user PCs not shown.

  In FIG. 13, a distribution application 521 is arranged on the user PC 520. The distribution application 521 is a network application that executes distribution processing of image data scanned by the image forming apparatus 510. The distribution application 521 includes an activation notification unit 5211, a cooperation unit 5212, an application information management file 5213, a distribution unit 5214, and the like.

  When the distribution application 521 is activated, the activation notification unit 5211 notifies the network application management server 530 that the distribution application 521 has been activated. The cooperation unit 5212 controls communication (information exchange and the like) with the image forming apparatus 510. The application information management file 223 is a file that stores setting information for the distribution application 521. The distribution unit 5214 is a logic unit of the distribution application 521 (part specific to the distribution application 521), and executes image data distribution processing. Other than the distribution unit 5214, the network application having other functions is also provided. The network application having another function has logic for realizing the other function instead of the distribution unit 5214.

  In FIG. 13, only one net application is arranged on the user PC 520, but a plurality of net applications may be arranged on one user PC 520.

  The net application management server 530 is a computer having an advertisement unit 531, an intermediary unit 532, a job operation unit 533, a log recording unit 534, and the like. In response to the activation notification (activation notification) from the network application, the advertising unit 531 issues an advertisement indicating that the network application has been activated (broadcast or multicast) on the network. The mediation unit 532 mediates communication between the network application and the image forming apparatus 510. The job operation unit 533 receives an operation request for a distribution job being executed or accumulated in the user PC 520 from the administrator, and transmits the operation request to the image forming apparatus 510. The log recording unit 33 receives an event that has occurred regarding a distribution job from the image forming apparatus 510 and records a log regarding the distribution job in the storage device of the network application management server 530.

  The image forming apparatus 510 may be similar in hardware to the first embodiment (see FIG. 3). The image forming apparatus 510 according to the second embodiment includes, as software, a network application detection unit 511, a UI control unit 512, a network application cooperation unit 513, a function control unit 514, a network application management table 515, an unauthorized request detection unit 516, and the like. Have

  The net application detection unit 511 detects the presence of a net application based on the advertisement issued from the net application management server 530 and registers the application information included in the advertisement in the net application management table 515. The net application management table 515 is a table for managing application information. The UI control unit 512 receives an input such as an instruction to start a net application from the user. The network application cooperation unit 513 controls communication with the network application. The function control unit 514 controls the hardware of the image forming apparatus 510 in response to a request from the network application. For example, scanning or printing is executed under the control of the function control unit 514. The unauthorized request detection unit 516 detects an operation request for a distribution job from an unauthorized terminal.

  Hereinafter, the processing procedure of the distribution system 2 will be described. FIG. 14 is a sequence diagram for explaining a processing procedure when the distribution application is activated.

  When the distribution application 521 is activated in the user PC 520, the activation notification unit 5211 of the distribution application 521 transmits the application information stored in the application information management file 5213 to the advertisement unit 531 of the network application management server 530. The activation of the distribution application 521 is notified (S301).

  FIG. 15 is a diagram illustrating a configuration example of application information. As shown in the figure, the application information includes an application ID, a linkage function identifier, a net application address, a display name, icon data, setting information, and the like.

  The application ID is identification information uniquely assigned to each network application. The cooperation function identifier is information for identifying a function (in other words, a function used by the network application) that the image forming apparatus 510 that cooperates with the network application needs to have. Examples of the linkage function identifier include “print” and “scan”. “Print” indicates a print function. “Scan” indicates a scan function. The distribution application 21 uses the scan function of the image forming apparatus 510. Therefore, in the example of FIG. 15, “scan” is the linkage function identifier.

  The net application address is identification information (for example, URL) for uniquely identifying each net application in network communication. The display name is a character string for displaying the name of the network application. The icon data is icon data for displaying a net application. The setting information is information including a setting value for the execution condition of the net application. That is, the behavior of the network application can be changed by changing the setting information. For the distribution application 521, setting information regarding scanning, setting information regarding distribution, and the like are included in the setting information of the application information.

  Subsequently, in response to receiving the application information, the advertising unit 531 of the network application management server 530 advertises the application information on the network (broadcast or multicast). The advertised application information is received by the network application detection unit 511 of the image forming apparatus 510 (S302). When there are a plurality of image forming apparatuses 510, the same advertisement is received by the network application detection unit 511 of each image forming apparatus 510.

  Based on the cooperation function identifier (scan) included in the application information, the net application detection unit 511 is configured so that the device (image forming apparatus 510) to which the network application detection unit 511 belongs is a network application (distribution application 521) related to the application information. ) And can be linked. The image forming apparatus 510 has a scan function. Therefore, the network application detection unit 511 of the image forming apparatus 510 determines that the network application can be linked, and registers the received application information in the network application management table 33.

  As described above, the distribution application 521 is registered in the image forming apparatus 510. That is, the existence of the distribution application 521 is recognized by the image forming apparatus 510. Accordingly, the distribution application 521 can be used from the image forming apparatus 510 (that is, the distribution job is executed).

  FIG. 16 is a sequence diagram for explaining a delivery job processing procedure according to the second embodiment.

  When a user of the image forming apparatus 510 inputs an instruction to use a net application to the image forming apparatus 510, the UI control unit 512 displays icon data included in the application information registered in the net application management table 515. Based on the above, the network application list screen is displayed on the operation panel 15 (S401). On the net app list screen, a list of net app icons registered in the net app management table 515 is displayed. In the present embodiment, the application information registered in the network application management table 515 is only related to the distribution application 521. Therefore, an icon corresponding to the distribution application 521 is displayed on the net application list screen in the present embodiment.

  When an icon corresponding to the distribution application 521 is selected by the user on the net application list screen and the start key on the operation panel 15 is pressed, the function control unit 514 starts a distribution job. When starting a distribution job, the distribution control unit 123 assigns a unique ID (job ID) to each distribution job to the distribution job to be started, and generates an entry corresponding to the job ID in the job management table. The configuration of the job management table may be the same as that of the first embodiment (see FIG. 6).

  Subsequently, the function control unit 514 acquires the application information of the selected distribution application 521 from the network application management table 515, and based on the cooperation function identifier (scan) and the setting information included in the application information, A scan is executed (S402). That is, the function control unit 514 causes the scanner 12 to scan a document set on the image forming apparatus 510 by the user, and outputs the image data obtained as a result to the network application cooperation unit 513 as a function execution result.

  The network application cooperation unit 513 transmits the image data and job ID as the function execution result to the cooperation unit 5212 of the distribution application 521 (S403). Before or after the transmission of the image data, the net application cooperation unit 513 updates the status of the distribution job in the job management table to “processing”.

  When the cooperation unit 5212 receives the job ID and the image data, the cooperation unit 5212 registers the job ID in the job queue. Also, the cooperation unit 5212 stores the received image data in the storage device of the user PC 520 in association with the job ID. Subsequently, the distribution unit 5214 acquires image data based on the job ID registered in the job queue, and distributes the image data to the distribution destination set in the application information management file 5213 (S404).

  When the processing by the distribution unit 5214 is completed, the cooperation unit 5212 notifies the completion of the distribution job to the network application cooperation unit 513 of the image forming apparatus 510 (S405). The net application cooperation unit 513 updates the status of the job ID included in the notification to “completed” in the job management table. Subsequently, the net application cooperation unit 513 transmits a job completion event including the job ID and an identifier indicating normal termination as attribute information to the log recording unit 534 of the net application management server 530 (S406). The log recording unit 534 that has received the job completion event records a log related to the distribution job in the storage device of the network application management server 530 based on the attribute information of the job status event.

  Next, cancellation of a distribution job from the network application management server 530 will be described. FIG. 17 is a sequence diagram for explaining the processing procedure of the delivery job cancel processing from the network application management server. In the figure, the network application management server 530 is operated by an administrator.

  For example, when a job list display instruction is input by the administrator via the job operation screen displayed on the display device of the network application management server 530 by the job operation unit 533 (S431), the job operation unit 533 receives the distribution job. The request for acquiring the list information is transmitted to the network application cooperation unit 513 of the image forming apparatus 510 (S432). The net application cooperation unit 513 returns the distribution job list information registered in the job management table to the job operation unit 533 (S433). The job operation unit 533 displays the received distribution job list (job list) on the job operation screen (S434).

  Subsequently, when an arbitrary distribution job is selected from the job list by the administrator and the cancel button on the job operation screen is clicked (S435), the job operation unit 533 specifies the job ID of the selected distribution job. Then, a cancellation request for the distribution job is transmitted to the network application cooperation unit 513 (S436). Note that the distribution job that can be selected as a cancellation target in step S435 is a distribution job whose status is “start” or “processing”.

  When receiving the cancellation request for the distribution job, the net application cooperation unit 513 requests the fraud request detection unit 516 to confirm the validity of the cancellation request. The fraud request detection unit 516 compares the IP address of the cancel request source (the IP address included in the cancel request) with the IP address recorded in advance in the HDD 114 as the identification information of the network application management server 530, Is verified (S437). The fraud request detection unit 516 determines that the cancel request is illegal when the two do not match, and determines that the cancel request is valid when the two match. Here, since the net application management server 530 is the source of the cancel request, it is determined that the cancel request is valid.

  When the validity of the cancellation request is confirmed, the net application cooperation unit 513 designates the job ID to be canceled and transmits a distribution job cancellation request to the cooperation unit 5212 of the distribution application 521 (S438). Note that the net application cooperation unit 513 updates the status of the job ID in the job management table to “Canceled” before or after transmitting the cancel request.

  The cooperation unit 5212 deletes the job ID specified in the cancel request from the job queue, and deletes the image data associated with the job ID from the storage device of the user PC 520 (S439). As a result, the distribution job is canceled. If the cancellation is successful, the cooperation unit 5212 returns information indicating the success of the cancellation to the network application cooperation unit 513 together with the job ID (S440).

  When receiving the information indicating the successful cancellation, the net application cooperation unit 513 updates the status of the job ID in the job management table to “cancelled”. Subsequently, the net application cooperation unit 513 transmits a job completion event including the job ID and an identifier indicating completion due to cancellation as attribute information to the log recording unit 534 of the net application management server 530 (S441).

  The log recording unit 534 that has received the job completion event records a log related to the distribution job in the storage device of the network application management server 530 based on the attribute information of the job status event.

  Next, FIG. 18 is a sequence diagram for explaining a processing procedure in the case where cancellation is instructed for a distribution job completed in the second embodiment. In FIG. 18, the same steps as those in FIG. 17 are denoted by the same step numbers, and the description thereof is omitted as appropriate.

  In FIG. 18, for example, the distribution application 521 executes a distribution process related to a distribution job to be canceled while a cancel instruction is being performed in the job list (S451). Subsequently, the completion of distribution is notified to the network application cooperation unit 513 of the image forming apparatus 510 together with the job ID (S452). In response to the notification, the network application cooperation unit 513 changes the status corresponding to the job ID in the job management table to “completed”.

  Thereafter, a cancel request for the job ID is transmitted from the job operation unit 533 of the network application management server 530 to the network application cooperation unit 513 of the image forming apparatus 510 (S436). Here, the status of the designated job ID is “completed” and cannot be canceled. Therefore, the net application cooperation unit 513 transmits a job status event including the job ID and the identifier indicating the cancellation failure as attribute information to the log recording unit 534 of the net application management server 530 (S453). Further, in response to the delivery job completion notification (S452) from the linkage unit 5212 of the delivery application 21, the network application linkage unit 513 generates a job completion event including the job ID and the identifier indicating the normal end of the delivery job as attribute information. It transmits to the log recording part 534 of the network application management server 530 (S454).

  The log recording unit 534 of the net application management server 530 receives the job status event and the job completion event at the timing (S453, S454) and relates to the distribution job based on the attribute information of the job status event or the job completion event. The log is recorded in the storage device of the network application management server 530.

  Note that the context of the job status event in step S453 and the job completion event in step S454 can change depending on the timing. For example, a job status event may be notified after a job completion event is notified first.

  Next, FIG. 19 is a sequence diagram for explaining a processing procedure when a cancel instruction from the operation panel and a cancel instruction from the management terminal overlap in the second embodiment.

  For example, when a user selects a delivery job to be canceled on the job list screen displayed on the operation panel 15 of the image forming apparatus 510 by the UI control unit 512 and inputs a cancel instruction (S461), the network application cooperation is performed. The unit 513 designates the job ID of the distribution job to be canceled, and transmits a distribution job cancel request to the cooperation unit 5212 of the distribution application 521 (S462). The net application cooperation unit 513 updates the status of the job ID in the job management table to “cancelling” before or after transmitting the cancel request. The job list screen displays a list of delivery jobs whose job IDs are registered in the job management table.

  Subsequently (for example, immediately after step S461), the network application cooperation unit 513 issues a cancel request for the same distribution job as the distribution job instructed to be canceled from the operation panel 15 by the job operation unit 533 of the network application management server 530. Is received (S463). Note that step S463 corresponds to step S436 in FIG. In this case, based on the job management table, the net application cooperation unit 513 recognizes that the distribution job is being canceled (that is, has already been requested to be canceled), and does not make a cancellation request to the distribution application 521 again. .

  Subsequently, the network application cooperation unit 513 receives information indicating successful cancellation from the cooperation unit 5212 of the distribution application 521 (S464). Subsequently, the net application cooperation unit 513 updates the status of the distribution job that is the cancellation target to “cancelled” in the job management table. Subsequently, the net application cooperation unit 513 transmits a job completion event including, as attribute information, a job ID and an identifier indicating completion due to cancellation to the log recording unit 534 of the net application management server 530 (S465).

  In the second embodiment, the processing procedure corresponding to FIGS. 10, 11, and 12 is obvious from the above description, and thus the description thereof is omitted.
