Description

  The present invention relates to an image forming apparatus that executes a job.

  As the image forming apparatus, for example, there is a multifunction machine having a copy function, a printer function, a facsimile function, a mail function, a scan function, and the like. Such a multifunction device stores a job history in a storage unit when a job is executed, and further displays the history on a display unit when a user requests it.

By the way, some multifunction peripherals require a user to log in before using the functions of the multifunction peripheral. In such a multi-function peripheral, there is an apparatus that can set an item to be hidden in the history when the user does not want to disclose the history to other users (see Patent Document 1).
Also, some multifunction peripherals replace a portion of personal information with a specific identifier when creating a history including personal information based on job execution (see Patent Document 2).

JP 2005-324450 A JP 2009-199144 A

  As described above, when a multi-function peripheral executes a job, it stores a history related to the job. By the way, the history created by using the facsimile function, the mail function, and the like includes information on business partners such as a facsimile number and a mail address. For this reason, the user who owns the multifunction device may want to delete the history including the information on the business partner from the storage unit.

  However, when deleting the history from the storage unit, if there is a corporate spy that attempts to leak information in the enterprise using the facsimile function and the mail function, the user cannot track the act of spying. Therefore, assuming that most employees are spying outside the working hours of the company after returning home, it is better to keep the history in the storage unit outside the working hours.

In the invention described in Patent Document 1, when user identification information used for login authentication leaks, there is a case where login is performed by impersonating another person. In this case, the history stored in the storage unit may be leaked.
Furthermore, the invention described in Patent Document 2 generates a personal information management table in which personal information is associated with a specific identifier and stores the personal information management table in a storage unit. The personal information part of the personal information management table is encrypted with an encryption key. In the invention described in Patent Document 2, if the encryption key is leaked, there is a possibility that company secret information (history) may be leaked.
For this reason, it is better to delete the history from the storage unit as much as possible.

  An object of the present invention is to provide an image forming apparatus that stores a job history in a storage unit when a job is started in a predetermined time zone.

  The present invention includes a job reception unit that receives a job, a first storage unit that can store job history information related to a job, a time zone setting unit that sets a time zone for storing job history information in the first storage unit, A job execution unit that executes a job received by the job reception unit, and whether or not the job is started in the time zone set by the time zone setting unit when the job is executed by the job execution unit If the first time determination unit determines that a job has started in the time period, the job history information relating to the job is generated and stored in the first storage unit And an image forming apparatus including a storage control unit.

  According to the present invention, it is possible to provide an image forming apparatus that stores a job history in a storage unit when a job is started in a predetermined time period.

The timer 110 measures the time. The timer unit 110 includes, for example, a real-time clock that measures time.

  The card reader 120 (identification information input unit) receives user identification information. When an IC (Integrated Circuit) card (not shown) in which user identification information is stored is brought close to the card reader 120, the card reader 120 reads out the user identification information stored in the IC card.

The control unit 90 controls the document conveying unit 10, the document reading unit 20, the engine unit 3, the operation unit 70, and the like.
In addition, the control unit 90 includes a job reception unit 91, a time zone setting unit 92, a first time determination unit 93, a storage control unit 94, a data reception unit 95, a transmission destination determination unit 96, and a second time. The determination part 97, the setting part 98, and the login process part 99 are provided.

  The job reception unit 91 receives a job. A job is a unit of work given to the multifunction device 1. As an example, a job is generated when a key (not shown) to which a copy function is assigned displayed on the touch panel 72 is selected by the user and the start key 73 is operated by the user. When a job is generated, the job receiving unit 91 receives the job.

  The time zone setting unit 92 sets a time zone for storing job history information related to a job in the first storage unit 81. That is, the time zone setting unit 92 sets a time zone in which job history information is generated by the storage control unit 94 described later and stored in the first storage unit 81. The time zone is appropriately set based on the operation of the operation unit 70 by the user. As an example, the time zone is a non-working time zone when the multifunction device 1 is installed in an office.

  When the job is executed by the job execution unit 130, the first time determination unit 93 determines whether or not the job is started in the time zone set by the time zone setting unit 92. As a specific example, when the copy is executed by using the engine unit 3 or the like, or when data is transmitted to the outside of the multi-function device 1 by using the transmission unit 100, the first The time determination unit 93 determines whether the execution of the copy or the transmission of data has been started in the above-described time zone.

  Here, the first time determination unit 93 is, for example, a time when a key for selecting a copy function or a key for selecting a function for transmitting data (facsimile function or mail function) is selected. If the time is within the time zone, it may be determined that the job has started in that time zone. In addition, when the start key 73 is operated in order to execute the copy function or to execute the function of transmitting data, the first time determination unit 93 determines the time when the start key 73 is operated as the time described above. If the time is within the time zone, it may be determined that the job has started in that time zone.

  The storage control unit 94 generates job history information related to the job when the first time determination unit 93 determines that the job is started in the time period (when a predetermined condition is satisfied), and generates the first storage unit 81. The job history information stored in the first storage unit 81 includes, for example, the time when the job is executed, the user identification information that executed the job, the contents of the executed job, and the job that transmits data. Data destination.

In addition, the storage control unit 94 determines that the transmission unit 100 determines that the transmission destination input by the input unit 74 does not match the transmission destination included in the list information by the transmission destination determination unit 96 described later. When transmitted, job history information relating to data transmission is stored in the first storage unit 81. Details will be described later.
Further, the storage control unit 94 stores a job stored in the first storage unit 81 after logging in to the multifunction machine 1 by the login processing unit 99 when the second mode described later is set by the setting unit 98 described later. When the history information is deleted, the user identification information input by the card reader 120 is stored in the third storage unit 83. Details will be described later.

  The data receiving unit 95 receives data related to the job. For example, in the case of a job for transmitting data to the outside using the transmission unit 100, the data receiving unit 95 receives data to be transmitted to the outside. As a more specific example, when the job accepted by the job accepting unit 91 is a facsimile transmission job, image data corresponding to the original image read by the original reading unit 20 is accepted.

  The transmission destination determination unit 96 includes a transmission destination included in the list information stored in the second storage unit 82 in which the transmission destination input by the input unit 74 is received when the job reception unit 91 receives a job for transmitting data. It is determined whether or not it matches. That is, the transmission destination determination unit 96 determines whether or not the transmission destination input by the input unit 74 is a predetermined transmission destination. As a specific example, when the job received by the job receiving unit 91 is a job for facsimile transmission, the transmission destination determination unit 96 displays the facsimile transmission destination input by the input unit 74 and the list information. The destinations recorded in the (address book) are compared, and it is determined whether or not there is a destination input by the input unit 74 among the destinations of the list information.

  Here, the list information stored in the second storage unit 82 is displayed on the touch panel 72, and one of the transmission destinations is selected from the displayed list information (transmission destination), and the selected transmission destination is a facsimile. When the transmission destination (mail transmission) is set as the transmission destination, the transmission destination determination unit 96 does not perform the above-described determination.

  As described above, the storage control unit 94 performs data transmission by the transmission unit 100 when the transmission destination determination unit 96 determines that the transmission destination input by the input unit 74 and the transmission destination included in the list information do not match. Is transmitted, job history information related to data transmission is stored in the first storage unit 81. That is, the storage control unit 94, when the transmission destination determination unit 96 determines that the transmission destination input by the input unit 74 is not a predetermined transmission destination, regardless of the determination result of the first time determination unit 93, Job history information related to data transmission is stored in the first storage unit 81.

  The second time determination unit 97 determines whether or not the current time measured by the time measuring unit 110 is a time within the time zone set by the time zone setting unit 92. The second time determination unit 97 performs the above determination at a preset timing. Thereby, the 2nd determination part can reduce a processing burden compared with the case where it always determines.

  The setting unit 98 cannot delete the job history information stored in the first storage unit 81 when the second time determination unit 97 determines that the time measured by the time measuring unit 110 is within the time zone. The storage control unit 94 is set so as to be in the first mode. That is, the storage control unit 94 cannot delete the job history information stored in the first storage unit 81 when the setting unit 98 sets the first mode.

  On the other hand, the setting unit 98 stores job history information stored in the first storage unit 81 when it is determined by the second time determination unit 97 that the time measured by the time measuring unit 110 is not within the time period. The storage control unit 94 is set so as to be in the second mode in which can be deleted. That is, the storage control unit 94 can delete the job history information stored in the second storage unit 82 when the setting unit 98 sets the second mode.

  The login processing unit 99 performs login processing to the multifunction device 1 based on the user identification information input by the card reader 120 and the identification information stored in the fourth storage unit 84. That is, when the user identification information is read by the card reader 120, the login processing unit 99 determines whether there is identification information that matches the user identification information in the identification information stored in the fourth storage unit 84. To do. If there is identification information that matches the user identification information, the login processing unit 99 executes login processing to the multifunction device 1. On the other hand, if there is no identification information that matches the user identification information, the login processing unit 99 does not perform login processing to the multifunction device 1.

  As described above, the storage control unit 94 stores the job history stored in the first storage unit 81 after logging in to the MFP 1 by the login processing unit 99 when the setting unit 98 sets the second mode. When the information is deleted, the user identification information input by the card reader 120 is stored in the third storage unit 83. When the setting unit 98 sets the second mode, the storage control unit 94 performs an operation for deleting one or a plurality of job history information stored in the first storage unit 81 by the user. Delete one or more job history information. Further, when the job history information is deleted, the storage control unit 94 stores the user identification information used for the login process in the third storage so that the user who has performed the operation for deleting the job history information can be specified. Store in the unit 83.

  Next, the operation of the multifunction device 1 when a job is received will be described. FIG. 4 is a flowchart for explaining the operation of the multifunction machine 1 when a job is received.

  In step ST1, the control unit 90 (job reception unit 91) receives a job.

  In step ST2, the control unit 90 determines whether or not the job accepted in step ST1 is for data transmission. That is, the control unit 90 determines whether or not the job performs facsimile transmission or mail transmission. When data transmission is not performed (No), the control unit 90 advances the process to step ST3. In the case of performing data transmission (Yes), the control unit 90 advances the process to step ST5.

  In step ST3, the job execution unit 130 executes the job accepted in step ST1. As an example, the job execution unit 130 performs copying or the like.

  In step ST4, the control unit 90 (first time determination unit 93) determines whether or not the execution of the job in step ST3 has been started in the time zone (predetermined time zone) set by the time zone setting unit 92. To do. When the job is started in the predetermined time period (Yes), the control unit 90 advances the process to step ST7. If the job is not started in the predetermined time zone (No), the control unit 90 advances the process to step ST9.

  When “Yes” is determined in step ST2, in step ST5, the control unit 90 (transmission destination determination unit 96) determines whether or not to transmit data to a predetermined transmission destination. That is, the transmission destination determination unit 96 determines whether there is a transmission destination that matches the transmission destination input by the input unit 74 in the list information stored in the second storage unit 82. When data is not transmitted to a predetermined transmission destination (No), the control unit 90 advances the process to step ST6. When data is transmitted to a predetermined transmission destination (Yes), the control unit 90 advances the process to step ST8.

  In step ST6, the transmission part 100 transmits data to the designated transmission destination.

  When it is determined as “Yes” in step ST4 and after step ST6, in step ST7, the control unit 90 (storage control unit 94) generates job history information, and the generated job history information is the first one. The data is stored in the storage unit 81.

  If “Yes” is determined in step ST5, in step ST8, the transmission unit 100 transmits data to the designated transmission destination.

  If “No” is determined in step ST4 and after step ST8, in step ST9, the control unit 90 (storage control unit 94) does not generate job history information. 81 is not stored.

  After step ST7 and step ST9, the control unit 90 ends the process.

As described above, according to the multifunction machine 1 of the present embodiment, the following effects are achieved.
That is, in the MFP 1 according to the present embodiment, when the job is executed by the job execution unit 130, whether or not the job is started in the time zone (predetermined time zone) set by the time zone setting unit 92 is determined. Is determined by the first time determination unit 93. Furthermore, when the first time determination unit 93 determines that the job has been started in a predetermined time period, the multifunction device 1 generates job history information by the storage control unit 94 and stores the job history information in the first storage unit 81. .
As a result, if there is an illegal act of leaking information, the multifunction device 1 can track the illegal act based on the job history information. Further, when the start time of the job is within a predetermined time, the multifunction device 1 stores the job history information in the first storage unit 81, so that it is possible to suppress fraud.

In addition, when the job reception unit 91 receives a job for transmitting data, the multifunction device 1 matches the transmission destination input by the input unit 74 in the list information stored in the second storage unit 82. The transmission destination determination unit 96 determines whether there is a transmission destination to be transmitted. In this case, when the MFP 1 determines that there is no transmission destination of list information that matches the transmission destination input by the input unit 74 by the transmission destination determination unit 96, the transmission unit 100 transmits data. The job control information relating to data transmission is stored in the first storage unit 81 by the storage control unit 94.
When an illegal act is performed, it is considered that data (in-house information) is transmitted to a destination that is not registered in the list information (address book) of the multifunction device 1. For this reason, when the multifunction device 1 transmits data to a transmission destination not registered in the list information, the multifunction device 1 stores the job history information in the first storage unit 81. Based on this, fraud can be tracked.

Further, when the second time determination unit 97 determines that the current time is within a predetermined time zone, the multifunction device 1 cannot delete the job history information stored in the first storage unit 81. The storage control unit 94 is set by the setting unit 98 so as to enter the mode.
When cheating is performed, the job history information stored in the first storage unit 81 is likely to be deleted. Therefore, when the current time is a time within a predetermined time zone, the multifunction device 1 prohibits the job history information from being deleted. As a result, the multifunction device 1 can track an illegal act.

On the other hand, the multifunction device 1 can delete the job history information stored in the first storage unit 81 when the second time determination unit 97 determines that the current time is not within a predetermined time zone. The storage control unit 94 is set by the setting unit 98 so as to be in the two mode. When the setting unit 98 sets the second mode and the job history information stored in the first storage unit 81 is deleted, the multifunction device 1 displays the user identification information input by the card reader 120. The data is stored in the third storage unit 83 by the storage control unit 94.
Cheating is thought to occur outside the company's working hours. For this reason, outside the predetermined time zone (within the company's working hours), there is a low possibility that the job history information is deleted due to fraud. For this reason, the multifunction device 1 can delete the job history information when the current time is outside the predetermined time zone.
