  However, the conventional image forming apparatus is not only for information to be stored when a job occurs among a plurality of pieces of information included in the job history, but for information stored after the job has occurred. However, since a storage area for a job history must be secured in advance when a job occurs, there is a problem that the storage capacity for the job history is wasted.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus capable of reducing the storage capacity for job history.

  The image forming apparatus of the present invention includes a history storage unit that stores a job history that is a job history, a history writing unit that writes the job history to the history storage unit, and a history that reads the job history from the history storage unit And the history writing means, when the job is a transmission job that transmits to an external destination, and the destination is already stored in the history storage unit, the destination The destination specifying information, which is information for specifying the destination, is included in the job history, and the history reading unit reads the destination based on the destination specifying information.

  With this configuration, when the destination is already stored in the history storage unit, the image forming apparatus of the present invention can write the destination specifying information instead of writing the destination. The storage capacity for job history can be reduced. Therefore, the image forming apparatus of the present invention can reduce the storage capacity for the job history as compared with the conventional case.

Also, images forming apparatus includes an address registration section for registering in advance the destination used in transmission in the transmission job, the history writing means performs transmission the job to a destination outside In the case of a transmission job, when the destination is already registered in the destination registration unit, it is preferable to include the destination specifying information in the job history.

With this configuration, the images forming apparatus, if the destination is already registered in the destination registration unit, so instead of writing destination may be written to the destination identification information, in comparison with a structure in which the writing destination itself, the job The storage capacity for the history can be reduced.

  The image forming apparatus of the present invention further includes a history deleting unit that deletes the job history from the history storage unit, and the history writing unit stores the job history including the destination by the history deleting unit. When deleting, it is preferable to add the destination to the job history including the destination specifying information.

  With this configuration, when deleting the job history including the destination, the image forming apparatus according to the present invention newly generates the job history including the destination. The destination can be read based on the specific information.

  The history writing unit of the image forming apparatus of the present invention may be configured such that when the history deletion unit deletes the job history including the destination, the latest job history among the job histories including the destination specifying information. It is preferable to add the destination.

  The job history is usually deleted from the oldest one. The image forming apparatus according to the present invention adds a destination to the latest job history among the job histories including the destination specifying information when deleting the job history including the destination. Compared to the configuration in which destinations are added to job histories other than the latest job history, the number of deletions of job histories that include destinations can be reduced, and as a result, the number of destinations added to job histories can be reduced. Can do. Therefore, in the image forming apparatus of the present invention, when the history storage unit is configured by a storage device whose lifetime is determined by the number of times of writing, shortening of the lifetime of the history storage unit can be suppressed.

  The management method of the present invention is a management method for a job history in an image forming apparatus having a history storage unit that stores a job history that is a job history, wherein the job transmits to an external destination. If the destination is already stored in the history storage unit, destination specifying information that is information for specifying the destination is included in the job history, and the destination is determined based on the destination specifying information. Is read out.

  With this configuration, when the destination is already stored in the history storage unit, the image forming apparatus that executes the management method of the present invention may write the destination specifying information instead of writing the destination. Compared with the configuration, the storage capacity for the job history can be reduced. Therefore, the image forming apparatus that executes the management method of the present invention can suppress the storage capacity for the job history as compared with the conventional case.

  The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores programs and various data in advance, and a RAM (Random Access Memory) that is used as a work area of the CPU. . The CPU is an arithmetic processing unit that operates the control unit 11 by executing a program stored in the ROM. The RAM temporarily stores programs and various data when the programs are executed by the CPU.

  The control unit 11 reads the job history from the non-volatile storage device 12 and the history writing unit 11a as the history writing unit of the present invention that writes the job history to the non-volatile storage device 12 when the CPU executes the program. It functions as a history reading unit 11b as a history reading unit of the present invention and a history deletion unit 11c as a history deletion unit of the present invention that deletes a job history from the nonvolatile storage device 12.

  The nonvolatile storage device 12 is a storage device such as an HDD (Hard Disk Drive), an EEPROM (Electrically Erasable Programmable Read Only Memory), or a flash memory.

  The display unit 13 is a display device such as an LCD (Liquid Crystal Display).

  The operation unit 14 is an input device such as a button that forms a touch panel together with the display unit 13 or a button on the operation panel.

  For example, the printer unit 16 receives a job of image data generated by the scanner unit 15, a FAX job received by FAX from an external facsimile apparatus via the FAX communication unit 17, or a network communication unit 18 from an external apparatus. The printing device prints various jobs such as a print data job received via the print data.

  For example, the FAX communication unit 17 transmits the image data generated by the scanner unit 15 by FAX to an external facsimile device, or receives image data to be printed by the printer unit 16 from the external facsimile device. .

  For example, the network communication unit 18 transmits image data generated by the scanner unit 15 to an external device, or receives print data to be printed by the printer unit 16 from the external device.

  The non-volatile storage device 12 includes an address book 30 for pre-registering destinations used at the time of transmission in a transmission job that transmits to an external destination by FAX, e-mail, or the like, and a history that is written only at the start of the job. A certain start history 40, an end history 50 that is written only at the end of the job, and a destination history 60 that is a history written when the job is a transmission job are stored. The start history 40, the end history 50, and the destination history 60 are information written to the nonvolatile storage device 12 for each job. Further, the destination history 60 is information written to the nonvolatile storage device 12 for each destination. Accordingly, hundreds of destination histories 60 may be stored in the non-volatile storage device 12 for one job in the case of broadcast transmission, for example.

  In the address book 30, for example, the user specifically inputs a destination via the operation unit 14 in transmission by FAX communication via the FAX communication unit 17 or transmission by e-mail via the network communication unit 18. This information is registered in advance in the nonvolatile storage device 12 in order to save labor. Various types of information included in the address book 30 are input to the multifunction device 10 by the user via the operation unit 14 or input from the external device to the multifunction device 10 via the network communication unit 18, for example. Can do.

  FIG. 2 is a diagram showing information of one partner in the address book 30 registered in the nonvolatile storage device 12.

As shown in FIG. 2, the address book 30 includes an address book ID 31 that is information for identifying the other party, a fax destination 32 associated with the address book ID 31, and an e-mail associated with the address book ID 31. Destination address 33 is included for each partner. The FAX destination 32 includes the name of the other party and the FAX number. The e-mail destination 33 includes the name of the other party and an e-mail address. Note that the address book 30 shown in FIG. 2 is merely an example. In other words, the address book 30 is not limited to the FAX address 32 and the e-mail address 33, but can include addresses for various communication methods.

  FIG. 3A is a diagram illustrating a start history 40 stored in the nonvolatile storage device 12. FIG. 3B is a diagram showing an end-time history 50 stored in the nonvolatile storage device 12.

  As shown in FIG. 3A, the start history 40 includes a job ID 41 that is information for specifying a job, a reception number 42 indicating the order in which the jobs are received by the multifunction machine 10, and the job starts. A start time 43 indicating the received time, an executor 44 indicating the executor of the job, and a destination number 45 indicating the number of destinations when the job is a transmission job are included. Note that the start history 40 shown in FIG. 3A is merely an example. That is, the start history 40 is not limited to the exemplified information, and can include various information.

  As shown in FIG. 3B, the end-time history 50 includes a job ID 51, which is information for specifying a job, and a job such as a normal job end, a job end due to an error, and a job end due to cancellation. A job result 52 indicating the result of the above and an end time 53 indicating the time when the job ends are included. Note that the end-time history 50 illustrated in FIG. 3B is merely an example. That is, the end history 50 is not limited to the exemplified information, and can include various information.

  FIG. 4A is a diagram illustrating the destination history 60 stored in the nonvolatile storage device 12. FIG. 4B is a diagram illustrating a destination history 60 stored in the nonvolatile storage device 12, which is an example different from the example illustrated in FIG.

  There are two types of destination history 60, one shown in FIG. 4 (a) and one shown in FIG. 4 (b). Which of the destination history 60 shown in FIG. 4A and the destination history 60 shown in FIG. 4B is written in the nonvolatile storage device 12 will be described later. The destination history 60 shown in FIG. 4A shows a job ID 61 that is information for specifying a job, a destination ID 62 as destination specifying information that is information for specifying a destination, and a specific destination. A destination 63 that is a character string is included. The destination ID 62 may be information having only a small number, for example, and therefore requires less storage capacity than the destination 63 that is a character string. The destination history 60 shown in FIG. 4B is information in which the destination 63 is omitted compared to the destination history 60 shown in FIG. The destination history 60 shown in FIG. 4 is merely an example. That is, the destination history 60 is not limited to the exemplified information, and can include various information.

  The start history 40, end history 50, and destination history 60 related to the same job have the same job ID 41, job ID 51, and job ID 61. That is, the job ID 41, the job ID 51, and the job ID 61 are identification information for associating the start history 40, the end history 50, and the destination history 60 with each other.

  As described above, the nonvolatile storage device 12 is configured to store the address book 30 and constitutes a destination registration unit of the present invention. The nonvolatile storage device 12 stores a job history including a start history 40, an end history 50, and a destination history 60, and constitutes a history storage unit of the present invention.

  Next, the operation of the multifunction machine 10 will be described.

<Write job history>
The control unit 11 of the multifunction machine 10 starts the processing illustrated in FIG. 5 when starting a job.

  FIG. 5 is a flowchart of the operation of the control unit 11 that is started by starting a job.

  As shown in FIG. 5, the control unit 11 writes the start history 40 in the nonvolatile storage device 12 by the history writing unit 11a (S101).

  Next, the control unit 11 determines whether the job is a transmission job (S102).

  If the control unit 11 determines in S102 that the job is a transmission job, the control unit 11 starts executing the destination history writing process shown in FIG. 6 (S103).

  FIG. 6 is a flowchart showing the destination history writing process.

  As illustrated in FIG. 6, the control unit 11 targets one destination among the destinations included in the job (S121), and determines whether the target destination is the same as the destination registered in the address book 30. (S122). The control unit 11 may actually search the address book 30 to determine whether the target destination is the same as the destination registered in the address book 30. Further, the control unit 11 determines that the target destination is not the same as the destination registered in the address book 30 when the target destination is directly input by the user, and the target destination is an address. When input is made by using the book 30, it may be determined that the target destination is the same as the destination registered in the address book 30.

  When the control unit 11 determines in S122 that the target destination is the same as the destination registered in the address book 30, the control unit 11 determines the address book ID 31 of the destination determined in S122 to be the same as the target destination, and the job communication method. And the destination history 60 shown in FIG. 4B is written in the nonvolatile storage device 12 by the history writing unit 11a (S123). As described above, the address book 30 includes destinations for various communication methods such as a fax destination 32 and an e-mail destination 33 for the same address book ID 31. Accordingly, the control unit 11 writes the address book ID 31 and the communication method of the job to the nonvolatile storage device 12 by the history writing unit 11a, so that the FAX address 32, the e-mail address 33, etc. Destinations for various communication methods can be specified. Note that the job ID 61 of the destination history 60 written in S123 is the same ID as the job ID 41 of the start history 40 written in S101.

  If the control unit 11 determines in S122 that the target destination is not the same as the destination registered in the address book 30, it determines whether or not the target destination is the same as the destination 63 stored in the existing destination history 60. Judgment is made (S124).

  If the control unit 11 determines in S124 that the target destination is the same as the destination 63 stored in the existing destination history 60, the control unit 11 stores the destination 63 determined in S124 that it is the same as the target destination. The destination history 60 shown in FIG. 4B with the destination ID 62 of the history 60 as the destination ID 62 is written into the nonvolatile storage device 12 by the history writing unit 11a (S125). Note that the job ID 61 of the destination history 60 written in S125 is the same ID as the job ID 41 of the start history 40 written in S101.

  When determining in S124 that the target destination is not the same as the destination 63 stored in the existing destination history 60, the control unit 11 sets the new destination ID as the destination ID 62 and sets the target destination as the destination 63 in FIG. The destination history 60 shown in a) is written to the nonvolatile storage device 12 by the history writing unit 11a (S126). Note that the job ID 61 of the destination history 60 written in S126 is the same ID as the job ID 41 of the start history 40 written in S101.

  When the control unit 11 writes the destination history 60 to the nonvolatile storage device 12 in S123, S125, or S126, the control unit 11 determines whether or not all destinations included in the job are targeted (S127).

  If the control unit 11 determines in S127 that any destination included in the job is not yet targeted, the control unit 11 performs the process of S121 on the destination not yet targeted.

  On the other hand, if the control unit 11 determines in S127 that all destinations included in the job are targeted, the execution of the destination history writing process shown in FIG. 6 is terminated.

  As shown in FIG. 5, when the execution of the destination history writing process in S103 is completed, the control unit 11 determines whether or not the job has ended until it is determined that the job has ended (S104).

  Note that when the control unit 11 determines in S102 that the job is not a transmission job, the control unit 11 executes the process of S104 without executing the destination history writing process in S103.

  If the control unit 11 determines in S104 that the job has ended, the control unit 11 writes the end-time history 50 to the nonvolatile storage device 12 by the history writing unit 11a (S105), and ends the process shown in FIG. The job ID 51 of the end history 50 written in S105 is the same ID as the job ID 41 of the start history 40 written in S101.

  When the power of the multifunction device 10 is turned off during execution of the job, that is, during the processing of S104 shown in FIG. 5, when the multifunction device 10 is started up again, the control unit 11 does not turn off the power. The job that was being executed at the end of the process is terminated as an error.

  FIG. 7 is a flowchart of the operation of the control unit 11 when the multifunction machine 10 is activated.

  As illustrated in FIG. 7, the control unit 11 determines whether there is a job in which the job result 52 is not stored, that is, a job in which the start history 40 exists and the end history 50 does not exist. (S141).

  When the control unit 11 determines in S141 that there is a job for which the job result 52 is not stored, the control unit 11 targets one job among the jobs determined in S141 that the job result 52 is not stored (S142).

  Next, the control unit 11 writes the end-time history 50 of the target job into the nonvolatile storage device 12 by the history writing unit 11a (S143). Note that the job ID 51 of the end history 50 written in S143 is the same ID as the job ID 41 of the start history 40 of the target job. As the job result 52, for example, “job end due to power-off error” is written. As the end time 53, for example, the execution time of S143 is written.

  Next, the control unit 11 determines whether or not all jobs determined in S141 that the job result 52 is not stored are targeted (S144).

  When the control unit 11 determines in S144 that any job among the jobs determined in S141 that the job result 52 is not stored is not yet targeted, the control unit 11 executes the process in S142 for the job that is not yet targeted.

  On the other hand, when the control unit 11 determines in S144 that all jobs determined in S141 that the job result 52 is not stored are targeted, the process illustrated in FIG. 7 ends.

  If the control unit 11 determines in S141 that there is no job in which the job result 52 is not stored, the process illustrated in FIG. 7 is terminated without executing the processes of S142 to S144.

<Reading job history>
The job history written in the nonvolatile storage device 12 as described above can be confirmed by the user. For example, the control unit 11 can read the job history by the history reading unit 11 b in accordance with an instruction from the operation unit 14 and display the read job history on the display unit 13. Further, the control unit 11 reads out the job history by the history reading unit 11b in response to an instruction from an external device via the network communication unit 18, and transmits the read job history to the external device via the network communication unit 18. Thus, the job history can be displayed on the display unit of the external apparatus. Here, the history reading unit 11b can read the start history 40, the end history 50, and the destination history 60 for the same job based on the job ID 41, the job ID 51, and the job ID 61. That is, the history reading unit 11b can handle the start history 40, the end history 50, and the destination history 60 in which the job ID 41, the job ID 51, and the job ID 61 are the same as the job history for the same job.

  Note that since the end history 50 is written in the processing of S105 after the end of the job, the job result 52 which is information included in the end history 50 is still a non-volatile storage device when the job is being executed. 12 is not written. Therefore, the control unit 11 can execute the process shown in FIG. 8 when displaying the job result 52.

  FIG. 8 is a flowchart of the operation of the control unit 11 when the job result 52 is displayed.

  As illustrated in FIG. 8, the control unit 11 determines whether or not a job result 52 is stored in the nonvolatile storage device 12 for a job whose job history is to be displayed (S161).

  When determining in S161 that the job result 52 is stored in the nonvolatile storage device 12 for the job whose job history is to be displayed, the control unit 11 reads out the job result 52 stored in the nonvolatile storage device 12 as a history. The data is read by the unit 11b (S162), and the read job result 52 is displayed on the display unit 13 or a display unit of an external device (S163), and the process shown in FIG.

  On the other hand, when the control unit 11 determines in S161 that the job result 52 is not stored in the nonvolatile storage device 12 for the job whose job history is to be displayed, the display unit 13 or an external The information is displayed on the display unit of the apparatus (S164), and the process shown in FIG.

<Delete job history>
The job history is deleted from the oldest one according to a predetermined condition, such as the number of job histories exceeds a predetermined number, or the oldest job history becomes a job history more than a predetermined period before the present. .

  FIG. 9 is a flowchart of the operation of the control unit 11 when deleting the job history.

  As shown in FIG. 9, the control unit 11 determines whether or not the destination history 60 is included in the job history to be deleted (S181).

  When determining in S181 that the destination history 60 is included in the job history to be deleted, the control unit 11 targets one destination history 60 in the destination history 60 included in the job history to be deleted (S182). ), It is determined whether or not the destination 63 is included in the target destination history 60 (S183).

  If the control unit 11 determines in S183 that the destination 63 is included in the target destination history 60, the other destination history 60 stored in the nonvolatile storage device 12 is the same as the destination ID 62 of the target destination history 60. It is determined whether or not the destination ID 62 is stored (S184).

  When the control unit 11 determines in S184 that the same destination ID 62 as the destination ID 62 of the target destination history 60 is stored in the other destination history 60 stored in the nonvolatile storage device 12, the target destination history 60 Among the destination histories 60 in which the same destination ID 62 as the destination ID 62 is stored, the latest destination history 60 (see FIG. 4B) is added to the destination 63 as shown in FIG. 4A. It is written by 11a (S185), and it is determined whether or not all destination histories 60 included in the job history to be deleted are targeted (S186).

  If the control unit 11 determines in S183 that the destination 63 is not included in the target destination history 60, the control unit 11 executes the process of S186 without executing the processes of S184 and S185. When the control unit 11 determines in S184 that the same destination ID 62 as the destination ID 62 of the target destination history 60 is not stored in the other destination history 60 stored in the nonvolatile storage device 12, the process of S185 is performed. The process of S186 is executed without executing.

  If the control unit 11 determines in S186 that any destination history 60 included in the job history to be deleted is not yet targeted, the control unit 11 executes the processing in S182 for the destination history 60 that is not yet targeted.

  On the other hand, when the control unit 11 determines in S186 that all the destination histories 60 included in the job history to be deleted are targeted, the history deleting unit 11c deletes the job history to be deleted (S187), and FIG. The process shown in FIG. Also, when the control unit 11 determines in S181 that the destination history 60 is not included in the job history to be deleted, the control unit 11 deletes the job history to be deleted by the history deletion unit 11c (S187), as shown in FIG. The processing shown in FIG.

  As described above, when the destination 63 is already stored in the destination history 60 on the nonvolatile storage device 12 (YES in S124), the multifunction machine 10 can write the destination ID 62 instead of writing the destination 63. Therefore, the storage capacity for the job history can be reduced as compared with the configuration in which the destination 63 itself is written. Therefore, the multi-function device 10 can reduce the storage capacity for the job history as compared with the related art.

  If the destination is already registered in the address book 30 on the nonvolatile storage device 12 (YES in S122), the multifunction machine 10 may write the destination ID 62 instead of writing the destination 63 (S123). Compared with the configuration in which the destination 63 itself is written, the storage capacity for the job history can be suppressed.

  In addition, when deleting the destination history 60 including the destination 63, the multifunction machine 10 newly generates the destination history 60 including the destination 63 (S185), so the destination history 60 including the destination 63 is deleted. However, the destination 63 can be read based on the destination ID 62.

  The job history is usually deleted from the oldest one. When the multifunction device 10 deletes the destination history 60 including the destination 63, the multifunction device 10 adds the destination 63 to the latest destination history 60 among the destination history 60 including the destination ID 62. Therefore, the destination history 60 including the destination ID 62 is included. Compared to the configuration in which the destination 63 is added to the destination history 60 other than the latest destination history 60, the number of times of deleting the destination history 60 including the destination 63 can be reduced. The number of times of adding 63 can be suppressed. Therefore, when the non-volatile storage device 12 is configured by a storage device whose life is determined by the number of writes, such as a semiconductor memory such as an EEPROM or a flash memory, the multi-function device 10 suppresses shortening of the life of the non-volatile storage device 12. Can do. The multi-function device 10 may be configured to add the destination 63 to the destination history 60 other than the latest destination history 60 in the destination history 60 including the destination ID 62.

  In addition, the multi-function device 10 stores job ID 41, job ID 51, and job ID 61, which are identification information for associating each other with a start history 40, an end history 50, and a destination history 60, which are a plurality of histories obtained by dividing the job history. Therefore, it is not necessary to secure a plurality of storage areas for the start history 40, the end history 50, and the destination history 60 at the same time. Therefore, the multi-function device 10 can reduce the storage capacity for the job history as compared with the related art.

  Further, the history writing unit 11a classifies information included in the job history into one of a start history 40, an end history 50, and a destination history 60 according to the writing time of the information. For this reason, since the multifunction machine 10 has the same writing time of the reception number 42, the start time 43, the executor 44, and the number of destinations 45, which are information written in the same history as the start history 40, the reception number 42, the start Compared to a configuration in which the time 43, the executor 44, and the number of destinations 45 are written at various times, the number of times of writing to the start history 40 can be suppressed. Similarly, since the multifunction machine 10 has the same writing time for the job result 52 and the end time 53, which are information written in the same history as the end time history 50, the writing time for the job result 52 and the end time 53 varies. Compared with the structure which is, the frequency | count of writing with respect to the log | history 50 at the time of termination can be suppressed. Therefore, when the non-volatile storage device 12 is configured by a storage device whose lifetime is determined by the number of writes, such as a semiconductor memory, the multifunction device 10 can suppress a reduction in the lifetime of the non-volatile storage device 12.

  Further, when the start history 40 is written and the job result 52 of the job is not written, the multi-function device 10 determines that the job has not ended yet, that is, the job is being executed. Therefore, it is not necessary to write information indicating that the job has not ended yet as a result of the job. Therefore, the multifunction machine 10 can suppress the number of times of writing to the nonvolatile storage device 12 as compared with a configuration in which information indicating that the job has not been completed is written as a result of the job. Therefore, when the non-volatile storage device 12 is configured by a storage device whose lifetime is determined by the number of writes, such as a semiconductor memory, the multifunction device 10 can suppress a reduction in the lifetime of the non-volatile storage device 12.

  In addition, since the multifunction device 10 secures a storage area of an appropriate size according to the number of destinations for the destination history 60 that is a history of storing destinations, it always stores a large memory of a certain size for the history of storing destinations. Compared with a configuration that secures an area, the storage capacity for the job history can be reduced.

  Note that the multifunction device 10 may handle the job history for each user in writing, reading, and deleting the job history. For example, when the job history is written, the multi-function device 10 makes only the destination history 60 of the other job executed by the job executor that is the basis of the job history scheduled to be written this time as a determination target in the process of S124. It may be. Similarly, when deleting the job history, the multifunction machine 10 determines only the destination history 60 of another job executed by the job executor that is the basis of the job history scheduled to be deleted this time as the determination target in the process of S184. You may come to do.

  Further, the image forming apparatus of the present invention is a multifunction peripheral in the present embodiment, but may be an image forming apparatus other than the multifunction peripheral, such as a copier or a printer.
