Description

  The present invention relates to an image forming system and an image forming apparatus suitable for using an image forming apparatus such as a plurality of printers and copiers in a network environment.

  As is well known, a plurality of image forming apparatuses such as printers installed in a company or office are connected to a personal computer for each user via a network so that a plurality of users can share the system. Jobs instructed by the user via the personal computer are sequentially accepted, and the jobs are temporarily stored and registered in the memory unit, and the jobs can be executed in the order of acceptance.

  Conventionally, as an image forming system applied in such a network environment, for example, in Patent Document 1, if a print server that has received a job inquires of another print server about the processing time, and the other print server can process quickly, A technique for transferring the job to another print server is disclosed.

Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for, when an error occurs in a printer that is performing job distribution processing, substituting another job for the job processing and notifying the user of the substitution processed printer. .
JP 2000-231465 A JP 2001-105691 A

  By the way, in this type of system, after the user gives a large number of copy or print instructions to the image forming apparatus, the user may notice that another image forming apparatus is in an “empty” state. In this case, job processing time can be shortened by sharing job processing with this other image forming apparatus.

  However, in the former known technique, the entire job is merely transferred to another print server that can be processed quickly, and a part of the registered job cannot be distributed to other image forming apparatuses. Can not be shortened.

  In the latter known technique, the job after the occurrence of a printer error during job execution is merely subjected to proxy processing by another printer, and there is no guarantee that the subsequent processing time can be shortened by proxy processing.

  The present invention has been made in view of the above circumstances, and provides an image forming system and an image forming apparatus capable of shortening the time until job execution is completed by job distributed processing regardless of whether the job is being executed or waiting for processing. The task is to do.

  The above problem is that the first image forming apparatus executes the job being executed or waiting for processing registered in the first image forming apparatus among the plurality of image forming apparatuses on the network, and the second image forming process. This is solved by an image forming system comprising: a distribution unit that distributes the content to be executed by the apparatus; and a control unit that executes a job distributed by the distribution unit.

  In this image forming system, the contents of a job registered in the first image forming apparatus on the network and being executed or waiting to be processed are distributed to the first and second image forming apparatuses and executed.

  That is, after the user registers a job in the first image forming apparatus, the user knows that the second image forming apparatus is in an “empty” state, and performs a dispersion process involving the second image forming apparatus. If instructed, even if the job is being executed or waiting for processing, the contents are distributed to the first and second image forming apparatuses and executed in parallel. Time to completion is shortened.

  In this image forming system, the second image forming apparatus is configured to display a display unit and an execution or awaiting job registered in the first image forming apparatus on the display unit by an input operation. And a selection unit that selects the distribution target job from the jobs displayed on the display unit.

  In this case, after a job is registered in the first image forming apparatus, if a user away from the location inputs an operation using the operation unit of the second image forming apparatus, his job to be distributed is displayed on the display unit. Since it is displayed, the distribution target job can be easily identified. Further, by selecting the distribution target job from the displayed jobs by the selection means, the distribution processing instruction can be performed quickly.

  In addition, a user-owned portable terminal capable of communicating with each image forming apparatus within a communication area set in each of the first and second image forming apparatuses is provided, and the portable terminal includes the second image forming apparatus. In the communication area, job identification information (hereinafter also referred to as job ID information) or job registration user identification information (hereinafter also referred to as job ID information) acquired when the job is registered in the first image forming apparatus. (Hereinafter, also referred to as user ID information) is provided to the second image forming apparatus, and the second image forming apparatus specifies a distribution target job based on the transmitted identification information. It is good also as a structure provided with.

  In this case, after the user instructs the first image forming apparatus to execute the job, the job is acquired as the job is registered in the first image forming apparatus within the communication area with the second image forming apparatus. When the job ID information or job registration user ID information corresponding to the job is transmitted from the portable terminal to the second image forming apparatus, the second image forming apparatus uses the transmitted identification information. Specify the job to be distributed. Therefore, the user can specify the job to be distributed in the second image forming apparatus without requiring any operation.

  Furthermore, the distribution means may be configured to propose job distribution so that the processing is completed in the shortest time.

  In this case, efficient distribution processing of the distribution target job is performed.

  Further, the above-described problem is a distribution unit that distributes a job being executed or awaiting processing registered in another image forming apparatus on the network into contents executed by the other image forming apparatus and contents executed by the apparatus. The image forming apparatus includes a control unit that executes a job distributed to the apparatus by the distribution unit.

  In this image forming apparatus, after the user registers a job in another image forming apparatus, if the user notices that the apparatus is “empty” and indicates that distributed processing involving the apparatus is performed, Even when a job is being executed or waiting for processing, the content of the distribution target job is distributed to both of the image forming apparatuses and executed in parallel, so the time until the end of execution of the distribution target job is shortened Is done.

  According to the first aspect of the present invention, even if a job registered in the first image forming apparatus on the network is being executed or is waiting for processing, the contents are respectively stored in the first and second image forming apparatuses. Since it is distributed and executed in parallel, it is possible to shorten the time until the end of the execution of the job to be distributed, and to obtain the output product at an early stage.

  According to the second aspect of the present invention, after a job is registered in the first image forming apparatus, when a user away from this place performs operation input using the operation unit of the second image forming apparatus, the user who wants to perform distributed processing Are displayed on the display means, it is possible to easily identify the distribution target job. Further, by selecting the distribution target job from the displayed jobs by the selection means, it is possible to promptly perform the distribution processing.

  According to the third aspect of the present invention, after the user instructs the first image forming apparatus to execute the job, the job is registered in the first image forming apparatus within the communication area with the second image forming apparatus. When the job ID information or job registration user ID information corresponding to the job acquired along with is transmitted from the portable terminal to the second image forming apparatus, the second image forming apparatus is transmitted. Since the job to be distributed is specified based on the identification information, the user can specify the job to be distributed in the second image forming apparatus without any operation.

  According to the fourth aspect of the invention, since the distributed processing proposal that minimizes the processing time is made for the job to be distributed, the job can be processed efficiently.

  According to the fifth aspect of the present invention, it is possible to provide an image forming apparatus capable of distributing a part of a job being executed or waiting in another image forming apparatus, and to shorten the time until the end of the execution of the distribution target job.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic configuration diagram showing an image forming system according to an embodiment of the present invention.

  1, this image forming system includes a plurality of image forming apparatuses 1, 2, 3... And a user-owned terminal apparatus 11. It is connected via a network, for example, a LAN (Local Area Network) 12.

  Examples of the image forming apparatuses 1, 2, and 3 include a copying machine, a facsimile (FAX), a printer, and a scanner. Here, an MFP that integrates the functions of the copying machine, FAX, printer, scanner, and the like. (Multi Function Peripherals) is taken as an example.

  The MFPs 1 to 3 can exchange image data and control data with each other via a LAN.

  The terminal device 11 is composed of, for example, a personal computer (also referred to as a PC), but is not particularly concerned with this.

  FIG. 2 is a block diagram representatively showing the electrical configuration of the MFPs 1, 2, 3 as MFP 1.

  2, the MFP 1 includes a scanner unit 21, an image memory / image processing unit 22, a printer unit 23, an operation unit 24, a LAN interface (referred to as LANIF in the drawing) unit 25, a memory unit 26, and a control unit. 27.

  The scanner unit 21 reads an image of a document placed in a predetermined part such as a document table and converts it into image data.

  The image memory / image processing unit 22 temporarily stores the read original image or the image data received via the LAN interface unit 25 and performs predetermined image processing. The printer unit 23 The image data subjected to image processing is printed out.

  The operation unit 24 is used by a user to give a job execution instruction or perform distributed processing by setting or confirming a copy mode or a copy start operation, and includes various operation buttons including a job selection button 24a. And a display unit 24b composed of an LCD or the like for displaying operation input contents, job information, and the like. The job selection button 24a is for selecting a job to be distributed among jobs displayed on the display unit 24b.

  The LAN interface unit 25 is used to exchange image data and control data with an external device, that is, another MFP 2 (3) or the PC 11.

  The memory unit 26 registers jobs to be executed. Specifically, the memory unit 26 stores job contents and various data, and sequentially updates and stores the progress of job execution.

  The control unit 27 determines whether or not the job stored / registered in the memory unit 26 can be distributed by another second MFP 2 (3) in addition to the overall control of each unit. It also functions as the unit 27, and when it is determined that distributed processing of the registered job is possible, a distributed processing plan that can process the job to be distributed in the shortest time is created and displayed on the display unit 24b. The job to be distributed has a function of executing processing involving the second MFP 2 (3) based on the distribution processing plan.

  In the image forming system configured as described above, when a user copies an original image using the MFP 1, if the user presses the start button in a copy mode in which job processing conditions are set using the operation unit 24, the original image is displayed. Is read by the scanner unit 21, and the read image signal is converted into image data.

  The image data is subjected to predetermined processing by the image memory / image processing unit 22 and then printed out on a sheet by the printer unit 23 in accordance with print setting conditions.

  At this time, a series of operations of each unit is controlled by the control unit 27, and a job is registered in the memory unit 26. In addition to storing the copy mode, the progress of processing is sequentially updated. It is remembered.

  When the user uses the MFP 1 as a printer, the image data transmitted by the user via the PC 11 and the print mode of the image data are obtained via the LAN I / F unit 25. The image data is processed by the image memory / image processing unit 22 in accordance with the acquired print mode, and then printed out on paper by the printer unit 23 in accordance with print setting conditions.

  At this time, a series of operations of each unit is controlled by the control unit 27, and a job is registered in the memory unit 26 and its print mode is stored, and the progress of processing is sequentially updated. Is remembered.

  Next, job distribution processing by the image forming system configured as described above will be described.

  Assume that the user uses the MFP 1 to copy a document image. The user operates the operation unit 24 of the MFP 1 to instruct the copy mode to “copy 10 copies using the sort function for 5 A4 originals” as shown in FIG. When instructed (press the start button), the copying operation by the MFP 1 is started.

  While copying is being executed in the MFP 1, the user leaves the MFP 1 and comes close to another MFP 2 that is currently in the “free” state, knowing that this MFP 2 is in the “free” state, and shortening the copy processing time. Therefore, it is assumed that distributed processing involving the MFP 2 that is “vacant” for the job is performed.

  First, in order to use the MFP 2, when the user inputs unique identification (ID) information (ID = A in this embodiment) of the MFP 1 using the operation unit 24 of the MFP 2, the MFP 2 controls the control unit 27. Under the control, the MFP 1 is inquired of the MFP 1 through the IF unit 25 as to whether there is job information being executed or waiting for processing.

  In response to this inquiry, the MFP 1 notifies the MFP 2 via the LAN interface unit 25 of the contents stored in the memory unit 26, that is, the table information shown in FIG.

  Now, according to this table information, the MFP 1 is currently executing the second copy (2/10 copies) for a job of “10 copies of 5 A4 originals using the sort function”. The processing time is 8 minutes, and it can be seen that there are no reservations for other jobs.

  In the MFP 2, the job list of the received table information is displayed on the display unit 24 b of the operation unit 24 according to an instruction from the control unit 27. Thus, the user can easily recognize that the job is instructed to be executed by looking at the displayed job list.

  If the user intends to distribute the job, the user designates the job as a distribution target job by using the job selection button 24a of the MFP 2. In response, the determination unit 27a in the MFP 2 determines whether or not distributed processing is possible for the job.

  The job being executed in the MFP 1 is a job that uses the sort function. The MFP 2 does not have a double-sided copy function as indicated by a cross mark in the in-memory table of FIG. As shown, since it has a sort function, the job can be distributed.

  Note that the MFP 1 is currently executing the second copy from the table information in FIG. 3A, while the MFP 2 has no job reservation from the table information in FIG. 3B. .

  Next, the job processing status will be described with reference to FIG.

  Before the distributed processing shown in FIG. 5 (A), the MFP 1 is currently executing the second copy at the present time (indicated by a triangle), and it takes 8 minutes to complete 10 copies. This indicates a “vacant” state in which the above process is not performed. In this embodiment, it is assumed that the MFP 2 has a processing speed twice that of the MFP 1.

  When the MFP 2 receives a distribution processing instruction, the MFP 2 examines a distribution method for ending the job being executed in the MFP 1 in the shortest time based on the situation shown in FIG. Note that the table information includes information such as the image memory capacity and processing speed of the job, whereby the transfer time and printout time can be calculated.

  Specifically, it takes 2 minutes for the control unit 27 of the MFP 2 to transfer the image data of the job from the MFP 1 to the MFP 2 to be distributed based on the table information obtained from the MFP 1. It is calculated that the hit printout time requires 30 seconds.

  From this calculation result, a distributed processing plan that can finish the job in the shortest time from the transfer start time is shown in FIG. In other words, the MFP 1 performs the four copies from the third to sixth copies in addition to the two copies currently being executed, and the MFP 2 processes the four copies from the seventh copy to the tenth copy. The process can be completed in 4 minutes. Then, the control unit 27 of the MFP 2 displays the distributed processing plan on the display unit 24b as shown in FIG. On the display screen, a determination button unit 240 is also displayed for allowing the user to determine whether or not it is a distribution selection instruction (YES) (NO).

  If the user who sees the distributed processing plan displayed on the display unit 24b of the MFP 2 decides to execute the distributed processing (touching “YES”), the distributed processing plan is transferred from the MFP 2 to the MFP 1, while the MFP 2 Also, distributed processing is executed.

  As described above, even if the job is already being executed in the first MFP 1, if it is determined that the job can be distributed in the “free” MFP 2, the job to be distributed is only the first MFP 1. In addition, since processing is executed in parallel in the MFP 2, the job completion is accelerated.

  When the job is distributedly processed, the table information in the memory unit 26 of the MFP 1 is updated and stored in a state corresponding to the distributed processing proposal as shown in FIG. The table information is also updated and stored in a state corresponding to the distributed processing proposal as shown in FIG.

  Next, an example in which a job waiting for processing in the MFP 1 is distributed to another MFP 2 will be described with reference to FIGS.

  Assume that the user makes a reserved copy using MFP 1 that is executing another job, and the copy mode at this time is, for example, as shown in FIG. “10 copies” is instructed.

  When the copy mode instruction is accepted by the MFP 1, the reserved copy operation is started by the user's start instruction (pressing the start button).

  Here, when the user leaves the MFP 1 and comes close to another MFP 2 that is currently in an “empty” state, the MFP 2 knows that the MFP 2 is in an “empty” state in which no job is being executed. It is assumed that distributed processing involving the MFP 2 is performed for the reserved job.

  First, in order to use the MFP 2, the user inputs identification (ID) information (ID = A) of the MFP 1 using the operation unit 24 of the MFP 2. As a result, the MFP 2 inquires of the MFP 1 that is executing the job via the IF unit 25 whether there is job information that is being executed or waiting for processing.

  In response to this inquiry, the MFP 1 reads out the storage contents of the memory unit 26, that is, the table information shown in FIG. 7A and notifies the MFP 2 via the IF unit 25. From this table information, it can be seen that the MFP 1 is currently executing a job of “25 copies of one A4 original”, and it takes 2 minutes to complete the execution. It can be seen that there is a reservation for job 2 (job ID 2).

  The MFP 2 displays the received job list of the table information on the display unit 24 b of the operation unit 24 according to an instruction from the control unit 27, so that the user can make a reservation for the job 2 by looking at the displayed job list. Can be easily recognized.

  Since the user intends to perform distributed processing of job 2, when the displayed job 2 is designated as a distributed selection job by operating the job selection button 24a, the MFP 2 determines whether the determination unit 27a can perform distributed processing. To do.

  The MFP 2 does not have a double-sided copy function as indicated by a cross in the table of FIG. 7B, but has a sort function as indicated by a circle. As shown in the table of FIG. 7A, the job 2 to be distributed is a job that uses only the sort function, so it is determined that distributed processing using the MFP 2 is possible.

  Next, the job processing status will be described with reference to FIG.

  At the present time (indicated by Δ in FIG. 9), the MFP 1 is executing the previous job 1 as shown in FIG. 9A, and it takes 2 minutes to complete the execution of the job 1. Thereafter, it can be seen that the processing of job 2 requires 10 minutes. Further, as shown in FIG. 9B, it can be seen that the MFP 2 is in a “vacant” state in which nothing is processed.

  The control unit 27 in the MFP 2 creates a distributed processing plan that can process the job 2 in the shortest time based on the contents of the in-memory table shown in FIG. First, it takes 2 minutes to transfer the image data of the job 2 from the MFP 1 to the MFP 2 from the contents of the table in the memory of the MFP 1 obtained earlier, and the printout time per copy is 30 seconds (the MFP 2 sets the MFP 1 to the MFP 1). (The processing speed is twice as high).

  As a result, FIG. 9B shows a distributed processing plan that can finish the execution of job 2 in the shortest time from the present time. In other words, it can be understood that the job 2 can be processed by the MFP 1 for 3 copies and the MFP 2 for 7 copies, and the processing can be completed in 5 minutes 30 seconds. At this time, the image transfer from the MFP 1 to the MFP 2 is performed in parallel with the execution of the previous job 1 by the MFP 1.

  Then, the MFP 2 displays this distributed processing plan on the display unit 24b. If the user sees the distributed processing plan displayed on the display unit 24b and selects the distributed execution, the distributed processing plan is transferred from the MFP 2 to the MFP 1. On the MFP 2, the distributed processing is also performed for the job to be distributed. Is executed.

  As described above, even if the job is waiting for processing in the first MFP 1, if it is determined that the job 2 can be distributed in the “free” MFP 2, the processing of the job to be distributed is the first. Since this is executed in parallel not only in the MFP 1 but also in the MFP 2, the completion of the job is accelerated. Furthermore, the efficiency of job execution is high because of processing based on the optimal distributed processing plan.

  In this distributed processing, the processing contents shown in FIG. 8A corresponding to the distributed processing proposal are stored as a table in the storage unit 26 of the MFP 1, and the distributed processing proposal is also stored in the storage unit 26 of the MFP 2. The processing content shown in FIG. 8B corresponding to is stored as a table.

  Incidentally, the former example shown in FIG. 3 to FIG. 5 describes the distributed processing of the job 1 when the MFP 1 is executing the distributed processing target job 1 and the MFP 2 is “empty”. In the latter example shown in FIGS. 7 to 9, the distribution process of the job 2 when the MFP 2 is already executing the previous job 1 and the job 2 is waiting for processing and the MFP 2 is “empty” has been described. However, the present invention is not limited to this, and even in various job processing situations, as long as it is determined that job distribution processing is possible, the same effect can be achieved by applying the distribution processing.

  In the above description, the distributed processing is performed based on the sort copy. However, the present invention is not limited to this. For example, distributed processing based on the number of documents may be used. For example, when 100 original images are copied in one copy, the MFP 1 can process the 1st to 60th images and the MFP 2 can process the 61st to 100th images.

  Further, the ID information of the MFP 1 is input when the job search or instruction is performed. However, the job search or instruction may be performed using the user ID information or the job ID information.

  For example, if user ID information is input when a copy instruction is issued using the MFP 1, the user ID is also stored in the memory table of the MFP 1 shown in FIG. For this reason, if the user ID information is input in the MFP 2, a job corresponding to the user ID is displayed. From the display, a job to be distributed may be selected. Can be easily identified.

  Further, for example, when the MFP 1 is used to issue a copy instruction, if the MFP 1 discloses the job ID related to the job to the user, the user can input the job ID and specify the job in the MFP 2. it can.

  Further, the present invention is not limited to a case where a copy instruction is issued from the MFP 1 but can be applied to a case where a print instruction is issued from the PC 11, for example. For example, after the user issues a print instruction from the PC 11 to the MFP 1, the user goes to the MFP 2 and inputs the ID information of the MFP 1 / the user ID information / the job ID information, thereby specifying the distributed processing target job and distributing Processing can be executed.

  Further, in the above example, the job instruction / distributed execution instruction is issued from the operation unit 24 of the MFP 2 which performs the distributed processing, but the distributed execution instruction is issued from the operation unit 24 of the MFP 1 having the job. You may do it.

  For example, when the job to be distributed is specified by the operation unit 24 of the MFP 1 and the ID information of the MFP 2 to be distributed is input, the distribution proposal of the MFP 1 and the MFP 2 may be displayed on the operation unit 24 of the MFP 1.

  Furthermore, when a user who has instructed the distributed execution of MFP 1 and MFP 2 to another MFP 3 on the MFP 2 side, similarly, the MFP 1, MFP 2 and MFP 3 use the MFP ID information / user ID information / job ID information. It is also possible to perform distributed execution. In this case, the distribution proposal is examined based on the in-memory table information of FIGS.

  Next, the flow of distributed processing in the image forming system will be described with reference to the flowchart of FIG.

  For example, when a user of a job being executed or waiting for processing in the MFP 1 wishes to come to the MFP 2 to distribute the job, for example, when the ID information of the MFP 1 or the like is input to the MFP 2, the control unit 27 of the MFP 2 causes the MFP 2 control unit 27 in S101. Recognize this. Thereafter, in S102, the control unit 27 displays the job list on the display unit 24b of the MFP 2 to which the ID information is input.

  When the user looks at the display of the job list and instructs to select his / her job as a distribution target job, the control unit 27 recognizes this in S103.

  In response to this instruction, the determination unit 27a of the MFP 2 determines whether or not distributed processing is possible for the job in S104. If distributed processing is possible (YES in S104), the MFP 2 determines in S105. The distribution proposal is displayed on the display unit 24b, and the process proceeds to S106. If distributed processing is not possible (NO in S105), the process ends.

  In S <b> 106, the control unit 27 of the MFP 2 determines whether or not to execute the job distribution process based on the operation of the determination button 240 by the user. If the job distribution process is to be executed (Yes in S106), the process proceeds to S107, and if the job distribution process is not to be executed (No in S106), the process ends.

  In S107, the distributed processing plan is transferred from the MFP 2 to the MFP 1, and the distributed processing in the MFP 2 is executed and the process ends.

  Next, another embodiment of the present invention will be described with reference to the drawings.

  FIG. 11 is a schematic configuration diagram showing an image forming system according to another embodiment of the present invention. FIG. 12 is a block diagram representatively showing the electrical configuration of MFPs 1, 2, and 3 in the image forming system as MFP 1. FIG. In FIG. 11, a portable terminal 13 is added, and in FIG. 12, a wireless interface unit (referred to as a wireless IF unit in the drawing) is added, and the other configurations are the same as those in FIGS. The reference numerals are attached and the description is omitted.

  11, reference numeral 13 denotes a user-owned portable terminal, for example, a PDA (Personal Digital Assistant), which can communicate with the MFPs 1, 2, 3,... Within each fixed communication area. This portable terminal 13 has user-specific ID information. When ID information is requested from the MFPs 1, 2, 3,... It is transmitted by the method.

  The mobile terminal 13 is not limited to the mobile terminal 13, and examples thereof include mobile devices such as various types of IC cards and mobile phones.

  In FIG. 12, reference numeral 28 denotes a wireless interface unit having a communication control function for configuring the mobile terminal 13 and a PAN (Personal Area Network). Specifically, IrDA (Infrared Data Association) or short distance using infrared rays. It supports Bluetooth using wireless.

  Next, job distribution processing using the portable terminal 13 will be described with reference to FIGS.

  FIG. 13 is a sequence diagram of an example in which job distribution processing is performed using job ID information.

  When the user who owns the portable terminal 13 instructs the copy mode via the operation unit 24 of the MFP 1, a job is accepted.

  When the acceptance of the job is completed, the MFP 1 transmits job ID information to the mobile terminal 13, and the mobile terminal 13 receives and stores this job ID information.

  Next, when the user owned by the mobile terminal 13 approaches the MFP 2, the mobile terminal 13 enters an area where communication with the MFP 2 is possible, and the mobile terminal 13 automatically transmits the stored job ID information to the MFP 2. .

  The MFP 2 searches the control unit 27 to identify whether the job corresponding to the received job ID information exists as a job waiting for processing or being executed on the network 12, and further identifies the job using the determination unit 27a. Determine whether the job can be distributed.

  If distributed processing is possible for the job, the MFP 2 transmits a distributed processing plan to the mobile terminal 13, and the mobile terminal 13 that has received this displays the distributed processing plan.

  When the user gives an instruction for distributed execution on the portable terminal 13 by looking at this, the MFP 2 that has received this instruction transmits the processing contents changed and distributed to the MFP 1. As a result, the MFP 1 and the MFP 2 execute distributed processing.

  FIG. 14 is a sequence diagram of an example in which job distribution processing is performed using user ID information instead of job ID information.

  When the user who owns the portable terminal 13 approaches the MFP 1 and enters the area where the portable terminal 13 can communicate with the MFP 1, the user ID information is requested from the MFP 1 to the portable terminal 13, and the user ID information transmitted from the portable terminal 13. Is obtained by the MFP 1. When the user issues a copy instruction via the operation unit 24 of the MFP 1 in this state, the job is accepted in a state associated with the obtained user ID information.

  Next, when the user who owns the mobile terminal 13 leaves the MFP 1 and approaches the MFP 2, the mobile terminal 13 automatically enters user ID information from the mobile terminal 13 when entering the area where the mobile terminal 13 can communicate with the MFP 2. Get it.

  The MFP 2 searches the control unit 27 to determine whether or not a job corresponding to the received user ID information exists on the network 15 as a job being executed or waiting for processing. Determines whether or not distributed processing is possible.

  If distributed processing is possible for the job, the MFP 2 transmits a distributed processing plan to the mobile terminal 13, and the mobile terminal 13 that has received this displays the distributed processing plan. When the user views this display and gives a distributed execution instruction on the portable terminal 13, the MFP 2 that has received this instruction transmits the processing contents of the distributed change to the MFP 1. As a result, distributed processing is executed in MFP 1 and MFP 2.

  In this case, just by the user who owns the mobile terminal 13 getting close to the MFP 2, information such as the possibility of distributed processing is immediately known, and subsequent instructions can be performed quickly.

  In the above example, an example in which a job distribution processing plan is transmitted from the MFP 2 to the portable terminal 13 and a distributed execution instruction is transmitted from the portable terminal 13 to the MFP 2 has been described. Since the MFP 2 is in the vicinity of the MFP 2, the MFP 2 may notify the user of the creation of the distributed processing plan with a buzzer sound or the like and may be displayed on the display unit 24 b of the MFP 2.

  In addition to the job ID information, if the job mode is configured to be transmitted and received between the MFP 1 and MFP 2 and the portable terminal 13, the job can be distributed even if the MFP 2 does not check with the MFP 1. It is possible to immediately determine whether or not.

  For example, if the portable terminal 13 obtains job mode information indicating whether or not there is a sort / double-side function of the target job from the MFP 1, the MFP 2 can distribute the job when the information is obtained from the portable terminal 13. It can be determined whether or not.
