Description

  The present invention relates to an image processing apparatus, an image processing system, and an image processing method, and more particularly, to an apparatus, a system, and a method for executing image processing based on job data recorded in a portable storage device.

  In recent years, so-called digital multifunction peripherals (hereinafter referred to as MFPs) have attracted attention as image processing apparatuses in homes and offices. This MFP is a device that collectively has a plurality of functions that a conventional copier, printer, scanner, facsimile, etc. each have as a single unit.

  Among these functions, the printer function is print control information for controlling the printer function by an MFP represented by a personal computer (hereinafter referred to as a PC), that is, an MFP connected to an information processing apparatus via a network. It is executed by receiving image data (including character data) to be printed from an electronic computer, a scanner or the like. Data communication media that physically configure the network include public communication lines and dedicated communication lines. In addition, data transmission using a portable storage medium (floppy (registered trademark) disk, USB memory, memory card, or the like) may be performed.

  The scanner function is a function for converting image data captured using the imaging unit and the input image processing unit into a predetermined data format (bitmap, JPEG, GIF, TIFF, PDF, etc.), and the image data is converted into the MFP main body. It is stored in the internal memory and transmitted via the data communication medium. Scanner function control information for controlling the scanner function can be input by the operator using the operation unit of the MFP. It is also possible to instruct the MFP to scan an image via a data communication medium and execute the scan.

  In addition, the facsimile function allows image data captured using the image capturing unit and the input image processing unit of the MFP, or data transmitted from an electronic computer or the like via a data communication medium to be transmitted to a public communication line including a telephone line. This is a function of transmitting to another apparatus having another facsimile function. Again, facsimile function control information for controlling facsimile transmission can be input from an operation unit of the MFP main body or an electronic computer connected via a data communication medium.

  As described above, the MFP is a very useful device that performs a plurality of functions by itself. In addition, since data processing is digitized, the affinity with an electronic computer or the like is very high. For this reason, MFPs are spreading with the momentum to replace conventional copiers, scanners, printers, facsimiles, and the like.

  However, there are disadvantages to the MFP. The MFP has the ability to process many functions alone. For this reason, for example, jobs from a plurality of operators may concentrate on one MFP. The MFP normally executes jobs sequentially in the order in which the jobs are received or according to a predetermined priority order. However, if any error occurs during job execution, the operation of the MFP including subsequent jobs stops. Unless measures such as eliminating the error or deleting the job causing the error are taken, the operation of the MFP is not restored, and the subsequent job processing is delayed. Even if the job is restored, the deleted job data is lost, and the operator needs to instruct the same or another MFP to perform the process again. Here, the job data includes data for selecting one of the functions of the MFP, and a parameter group (image size, color or monochrome, print paper size) that can be determined by the operator when executing the function. , Etc.) and other control information, and further, processed image data.

  Patent Document 1 discloses a means for avoiding deadlock of an image processing apparatus such as an MFP due to one job. In Patent Document 1, by recording image data that cannot be printed in a built-in external storage device, accidental occupation of the MFP or the like by one operator (operation stop of the MFP or the like due to an error or the like) is avoided.

  Patent Document 2 discloses a portable storage medium that stores data of unprocessed jobs and jobs being processed that are already received by the MFP or the like when an error occurs in the MFP or the like and temporarily stored in the MFP or the like. A means for minimizing the dissipation of job data caused by errors occurring in the MFP or the like is disclosed.

  In Patent Documents 3 to 7, the job contents for the MFP or the like are recorded in advance on a portable storage medium, and the operator sends the job data to the MFP or the like via the portable storage medium. Means for implementing are disclosed. By recording the job data on the portable storage medium, in general, the disadvantage of dissipating unprocessed job data due to the occurrence of an error or the like is improved.

  Patent Document 3 discloses a means for executing a print job recorded on a portable storage medium on an MFP or the like. Offline printing is realized by providing a means for recording a print job on a portable storage medium and sending job data to an MFP or the like.

  Patent Document 4 discloses means for directly printing image data recorded on a portable storage medium on an MFP or the like. By selecting image data to be printed from image data recorded on a portable storage medium, it is possible to suppress useless print output.

  Japanese Patent Application Laid-Open No. 2005-228561 discloses means for executing a scan on an MFP or the like according to a scan job recorded in advance on a portable storage medium, and recording image data generated by the scan on the portable storage medium. Similar to Patent Document 3, offline printing is realized by providing means for recording a print job on a portable storage medium and sending job data to an MFP or the like.

  Patent Document 6 discloses means for creating and printing image data output control data for printing a print job stored in a portable storage medium on a digital plain paper copier. Similar to Patent Document 3 and Patent Document 5, offline printing is realized by providing means for recording a print job on a portable storage medium and sending job data to an MFP or the like.

Patent Document 7 discloses means for executing a print job recorded on a portable storage medium on an MFP or the like. In particular, when printing based on print job data stored in a portable storage medium, if job data instructing color printing is input to an MFP that cannot perform color output, the job data is in a format suitable for monochrome output. Disclosed is a means for printing after conversion to.

<Image processing procedure>
Next, an image processing method using the system according to the present invention will be described with reference to the accompanying drawings.

The operator uses the PC 20 to create a job to be executed by the MFP 10a. The created job data is recorded in the USB memory 30. Here, the job recorded in the job data is, for example,
Print jobs that output desired image data,
For example, a scan job for converting a desired document into electronic data.
A copy job for copying a desired document, and

When the document to be transmitted is electronic data, image data of the document is further added.

  Job processing using the USB memory 30 will be described. When the job data is recorded in the USB memory 30, the operator removes the USB memory 30 from the PC 20 and attaches it to the USB port 11 of the MFP 10a. The information reading unit of the MFP 10a to which the USB memory 30 is attached checks the data contents recorded in the USB memory 30 and confirms the presence or absence of job data. When the presence of the job data is confirmed, the MFP 10a reads the job data, and the job execution unit executes the job according to the contents instructed by the job data.

<Job suspension due to error>
FIG. 3 shows a USB memory that is recorded in the storage device of the system controller 106 of the MFP 10a and executed when the CPU of the system controller 106 executes a job, and an error occurs and job processing is interrupted. 30 is a flowchart of a portion showing processing for 30. This error is caused when the MFP 10a cannot continue processing according to the instruction described in the job data, for example, when the MFP 10a does not have a function for performing the processing described in the job data (for example, the duplex printing function), and In this case, the MFP 10a malfunctions due to out of paper or paper jam.

  While the job is being executed, occurrence of an error is monitored (step S101). If no errors are found, continue the job. If an error occurs, the job currently being executed is interrupted (step S102).

  Next, it is determined whether or not the job currently being executed is a job registered from the USB memory 30 (step S103). If the job is a job registered from the USB memory 30, data indicating that the information recording unit of the MFP 10 a has been interrupted, that is, interrupt information is displayed in the data area for recording the job status in the USB memory 30. Recording is performed in association with the data (step S104). At this time, the reason why the job is interrupted is preferably recorded in the USB memory 30 at the same time. If the job is not a job registered from the USB memory 30, only the interruption process is executed (step S103). As described above, when an error occurs in the MFP 10 a, a job registered from the USB memory 30 is recorded in the USB memory 30 as being interrupted.

<Job suspension by operator instruction>
FIG. 3 shows an operation panel 12 that is recorded in the storage device of the system controller 106 of the MFP 10a and that the operator of the system controller 106 executes to execute a job. 7 is a flowchart showing a part of processing of the CPU of the system controller 106 of the MFP 10a for the USB memory 30 when a job interruption is instructed from FIG.

  While the job is being executed, it is monitored whether there is an instruction to interrupt the job by the operator (step S201). This monitoring is executed simultaneously with the error occurrence monitoring step shown in step S101 (FIG. 3). If the input of the stop instruction is not accepted, the job is continued. When a job interruption instruction is input by the operator, a process for immediately suspending the currently executing job is performed (step S202).

  Next, it is determined whether or not the interrupted job is a job registered from the USB memory 30 (step S203).

If the interrupted job is a job registered from the USB memory 30, first, a process selection image is displayed on the operation panel 12 (step S204). In this processing selection image,
1. Discard the interrupted job or
2. Resume an interrupted job, or
3. Save the interrupted state in the USB memory 30, or
Content that prompts the user to select one of them is included. The operator selects and inputs one of the above options from the above options using the operation panel 12. Here, “discard” of the job is selected when it is not necessary to continue the interrupted job any more. In this case, the MFP 10a clears the content of the job data. Further, the job data recorded in the USB memory 30 may be recorded with data indicating that the job has been processed, or the corresponding job data may be deleted from the USB memory 30. “Resume” of the job is selected when the suspended job is immediately resumed. In this case, the MFP 10a immediately resumes the suspended job. “Save” to the USB memory 30 is selected when the interruption information including information on the interruption state is stored in the USB memory 30 in association with the job data, and the interrupted job is once deleted from the MFP 10a. When the operator inputs the above selection to the MFP 10a, the MFP 10a executes processing according to the input content (step S206).

On the other hand, if the interrupted job is not a job registered from the USB memory 30 (NO in step S203), a process selection image is displayed on the operation panel 12 (step S205). In this processing selection image,
1. Discard the interrupted job or
2. Resume an interrupted job, or
Content that prompts the user to select one of them is included. The operator uses the operation panel 12 to select and input one of the above options. When the operator inputs the above selection to the MFP 10a, the MFP 10a executes processing according to the input content (step S207).

  After executing the process of step S206 or step S207, the MFP 10a proceeds to a process of executing the next registered job.

  As described above, when the process of the MFP 10 a is interrupted based on the operator's instruction, the job registered in the USB memory 30 is stored (recorded) in the USB memory 30 in the interrupted state. ) And the data indicating that the job is interrupted can be recorded in the USB memory 30 even if the option is interrupted by the operator's instruction.

  Therefore, the MFP 10a is provided with processing for the USB memory 30 according to <interrupt of job due to error> (FIG. 3) and <interrupt of job according to operator instruction> (FIG. 4), resulting in an error of the MFP 10a. When the job is interrupted according to an instruction from the operator, the fact that the job is interrupted can be recorded in association with the job data recorded in the USB memory 30.

<Resumption of job interrupted and stored in USB memory 30>
In FIG. 5, the data is recorded in the storage device of the system controller 106 of the MFP 10 a and is interrupted and stored in the USB memory 30 included in the job execution processing program recorded in the USB memory 30 of the CPU of the system controller 106. The flowchart of the part which restarts a job is shown.

  The presence / absence of the mounted (inserted) USB memory 30 is monitored (step S301). When the installation of the USB memory 30 is not recognized (in the case of NO), the subsequent processing is skipped, and after executing the processing of the MFP 10a not shown in the figure, step S301 is executed again.

  When the installation of the USB memory 30 is confirmed (in the case of YES), the MFP 10a checks the data in the USB memory 30 (step S302). Based on the result of the investigation, it is determined whether there is job data to be processed (step S303). When the existence of job data to be processed is not recognized (in the case of NO), the subsequent processing is skipped, and the processing of the MFP 10a not shown in the figure is executed, and then step S301 is executed again.

  If the existence of job data is recognized in the USB memory 30 (if YES is determined in step S303), the job data in the USB memory 30 is read (step 304). Then, the data relating to the job state recorded in the read job data, that is, status information is analyzed (step S305). Based on the analysis in step S305, it is determined whether the job represented by the read job data is an interrupted job (step S306). If the job is not an interrupted job and the job is in an unprocessed state, the job is executed (step S308).

  If the job represented by the read job data is an interrupted job, or if there is interrupt information associated with the job data (YES in step S306), the contents of the job data are further analyzed, Restore the job state. At this time, the job may be restored by changing the contents of the job so as to conform to the apparatus configuration and functions of the MFP 10a. Further, permission for the change may be obtained from the operator via the operation panel 12 (step S307).

  FIG. 6 is a flowchart showing details of the processing in step S307. First, the type of job described in the job data and mode data that is data relating to the job mode are checked (step S401). As described above, this mode data is data relating to a parameter group that is set in executing various jobs (printing, scanning, copying, facsimile transmission). For example, when the job is a print, the mode data includes a parameter group relating to settings such as printing paper size, finishing, double-sided printing or single-sided printing, color printing or monochrome printing, tint block, overlay, and watermark. For example, when the job is a scan, the mode data includes a parameter group for designating a scanned document sheet size, a double-sided scan or a single-sided scan, a color scan or a monochrome scan, a scan resolution, an output file format, and the like.

  Next, the current apparatus configuration of the MFP 10a is checked (step S402). By this investigation, it is possible to accurately grasp what device configuration it currently has. For example, the size of the paper placed in the paper tray, whether double-sided printing is possible, whether the toner to be mounted is only black, or whether toner for color printing is installed. It is also possible to grasp the remaining amount of toner installed. Based on this investigation, it is investigated whether or not the MFP 10a currently has a function of executing each mode described in the job data, and the result is recorded in the main body (step S403). Based on this investigation, if a non-executable mode setting is included, the setting for the non-executable mode is canceled, and the data related to the mode recorded in the job data is changed to a mode setting executable in the MFP 10a. (Step S404). Preferably, the release is notified to the operator using the operation panel 12, and the release is performed after obtaining the operator's permission. If the mode setting is changed in step S404, the MFP 10a restores the job in a suspended state under the mode setting (step S407). Returning to FIG. 5, as soon as the job is restored in an interrupted state, the job is resumed (step S309).

  By configuring the processing for the USB memory 30 of the MFP 10a as described above, it is possible to resume a job stored in the suspended state from the suspended state. When an error occurs due to a lack of functions of the MFP 10a, and a job that is interrupted and saved is executed, a mode that requires a function that the MFP 10a does not have is disabled, and the same interruption is performed. It can be avoided automatically. In addition, if the USB memory 30 is mounted on a machine different from the MFP 10a in which the job is interrupted, for example, the MFP 10b (FIG. 1), the interrupted job is resumed from the interrupted state on another machine. It can also be done easily. At this time, if the MFP 10b has the function that caused the error that the MFP 10a does not have, the job is resumed without changing the mode setting when the job is resumed in the MFP 10b, and a desired result is obtained. be able to.

<Resumption of job interrupted and saved in USB memory 30 via network>
When at least one of the MFPs 10a and 10b included in the system and the PC 20 are connected via the network 400, the job interrupted and stored in the USB memory 30 is attached to the PC 20, and the MFP 10a or 10 It is also possible to restart the job at 10b.

  FIG. 7 is a flowchart of a program for processing for resuming an interrupted job in the MFP connected to the network 400 when the interrupted job is included in the USB memory 30 attached to the PC 20.

  The CPU 202 of the PC 20 monitors whether the USB memory 30 is attached (inserted) to the USB port 21 (step S501). When the installation of the USB memory 30 is not recognized (in the case of NO), the subsequent processing is skipped, other processing not shown in this figure is executed, and step S501 is executed again.

  When the installation of the USB memory 30 is confirmed (in the case of YES), the PC 20 investigates the contents of the USB memory 30 (step S502). Based on the result of the investigation, it is determined whether there is job data to be processed by the MFP (step S503). If the MFP does not recognize the presence of job data to be processed (in the case of NO), the subsequent processing is skipped, other processing not shown in the figure is executed, and step S501 is executed again.

  If the presence of job data to be processed by the MFP is recognized in the USB memory 30 (if YES is determined in step S503), the job data to be processed by the MFP in the USB memory 30 is read by the data reading means (step S504). The read data relating to the job status recorded in the job data to be processed by the MFP is analyzed (step S505).

  Based on the analysis in step S505, the PC 20 determines whether the job represented by the read job data is an interrupted job (step S506). If the job is an interrupted job (YES), steps S507 and S509 are executed thereafter. If the job is not an interrupted job (in the case of NO), if the job is in an unprocessed state, steps S508 and S510 are subsequently executed.

  If the job represented by the read job data is an interrupted job (YES in step S506), one or more MFPs that are optimally connected to the network for restarting the job from the interrupted state are connected. The MFPs 10a and 10b are searched (step S507). This search for the optimum job resumption MFP searches the network 400 for an MFP having a function capable of executing the job type represented by the read job data, the set and enabled mode, and the like. Means that. Data relating to MFP functions necessary for this search may be stored in advance by the PC 20. Further, at the time of searching, the functions of the MFP may be inquired to the MFPs 10a and 10b connected via the network 400 at the same time.

  When the search is completed, the PC 20 then transmits job data to the MFP 10a listed by the search via the network 400 by the data transmission unit. The MFP 10a that has received the job data executes Step S307 and Step S309 (both refer to FIG. 5).

  On the other hand, if the job represented by the read job data is not an interrupted job (unprocessed job) (NO in step S506), the PC 20 connects the MFP that can execute the current job to the network. A search is made from one or a plurality of MFPs 10a and 10b, etc. (step S508). In this step S508, it may be planned to search for an MFP having an optimum function based on the contents of the read job data.

  When the search is completed, the PC 20 then transmits job data via the network 400 to the MFP 10a listed by the search. The MFP 10a that has received the job data executes the job.

  As described above, in the image processing system according to the embodiment of the present invention, job data is recorded in the USB memory 30, and the MFPs 10a and 10b read out the job data recorded in the USB memory 30, and execute the job. In addition, when a job is interrupted due to a functional limitation or malfunction of the apparatus or due to an operator instruction, the interrupted state is recorded in the USB memory 30, so that the interrupted job can be easily resumed. . In addition, the interrupted job can be resumed by a device different from the MFP that interrupted the job.

  It is also possible to resume the job by sending the job data of the suspended job to at least one MFP connected to the network 400 by mounting the USB memory 30 in which the job data is recorded on the PC. It is.

  The processing flow of the present embodiment has been described above. Next, examples of print job execution, suspension, and restart, and examples of scan job execution, suspension, and restart will be described. These examples are illustratively described to assist in understanding the present invention. These examples are not intended to define the scope of the invention.

<Execution example of print job>
The operator attaches the USB memory 30 to the PC 20 and registers a print job in the USB memory 30 by a predetermined operation. The print job includes data indicating that the job type is print, data regarding the job status, data regarding the print mode, image data of an image to be printed, and the like. At this point, of course, the job status is unprocessed.

  Next, the operator removes the USB memory 30 from the PC 20, and attaches (inserts) the USB memory 30 that was just removed to the USB port 11 of the MFP (for example, 10a) on which the job is to be executed. The MFP 10a to which the USB memory 30 is attached reads the contents of the USB memory 30, finds an unprocessed print job, and starts the print job (steps S301 to S306 and S308 in FIG. 5).

  When a print job is being executed, an error due to a malfunction or malfunction of the MFP 10a or an input of a job suspension instruction by a user instruction is confirmed (step S101 in FIG. 3 or step S201 in FIG. 4). (Step S102 in FIG. 3 or Step S202 in FIG. 4), and the status of the job is recorded in the USB memory 30 (Steps S103 and S104 in FIG. 3, or Steps S203 to S206 in FIG. 4). The operator removes the USB memory 30 and stores it until an opportunity to resume the interrupted job.

  The operator who has the opportunity to resume the interrupted job can connect the USB memory 11 to the USB port 11 of the MFP for which the job is to be resumed (which may be the same as or different from the MFP in which the job was interrupted earlier). Wear 30. When the MFP (for example, 10a) recognizes the USB memory 30 attached to the USB port 11, it reads the contents of the USB memory 30, finds a suspended print job, and based on the data related to the mode setting described in the job data The configuration is restored, and the print job is restarted (steps S301 to S306 in FIG. 5 and steps S307 and S309).

  In this way, the operator can obtain the remaining output of the interrupted print job. As described above, the registration of job data recorded in the USB memory 30 to the MFP 10 a can also be executed via the network 400.

<Execution example of scan job>
The operator attaches the USB memory 30 to the PC 20 and registers a scan job in the USB memory 30 by a predetermined operation. The scan job includes data indicating that the job type is scan, data regarding the job status, data regarding the scan mode, and the like. At this point, of course, the job status is unprocessed.

  Next, the operator removes the USB memory 30 from the PC 20, and attaches (inserts) the USB memory 30 that was just removed to the USB port 11 of the MFP (for example, 10a) on which the job is to be executed.

  The MFP 10a to which the USB memory 30 is mounted reads the contents of the USB memory 30, finds an unprocessed scan job, and starts the scan job (steps S301 to S306 and S308 in FIG. 5). At this time, the MFP 10a is a switch for starting scanning in accordance with the scan mode recorded in the USB memory 30 on the operation panel 12 in order to clearly indicate to the operator that scanning is performed based on data relating to the scan mode. A one-touch key may be displayed. The operator can confirm that the scan is executed according to the scan mode recorded in the USB memory 30 by pressing the one-touch key that makes the operation extremely simple.

  During execution of a scan job, when an error due to a malfunction or malfunction of the MFP 10a or an input of a job suspension instruction by a user instruction is confirmed (step S101 in FIG. 3 or step S201 in FIG. 4), job suspension processing is performed. (Step S102 in FIG. 3 or Step S202 in FIG. 4), and the status of the job is recorded in the USB memory 30 (Steps S103 and S104 in FIG. 3, or Steps S203 to S206 in FIG. 4). In the case of a scan job, image data of a document that has been read before being interrupted may be added to the job data of the interrupted job. The operator removes the USB memory 30 and stores it until the opportunity to resume the interrupted job.

  The operator who has the opportunity to resume the interrupted job can connect the USB memory 11 to the USB port 11 of the MFP for which the job is to be resumed (which may be the same as or different from the MFP in which the job was interrupted earlier). Wear 30. When the MFP (for example, 10a) recognizes the USB memory 30 attached to the USB port 11, it reads the contents of the USB memory 30, finds a suspended scan job, and based on the data related to the mode setting described in the job data The configuration is restored and the scan job is restarted (steps S301 to S306 in FIG. 5 and steps S307 and S309). At this time, the job may be resumed when the operator presses the resume one-touch key displayed on the operation panel 12.

  In this way, the operator can obtain the remaining output of the interrupted scan job. The scanned image data of the document may be recorded in the USB memory 30. Similar to the print job, the job data recorded in the USB memory 30 can be registered in the MFP 10 a via the network 400.

<Execution example of multiple print jobs>
In the execution example of the print job described above, there is one print job registered in the USB memory 30, but in this execution example, a case where a plurality of print jobs are registered will be described with reference to FIG. To do. As described above, the registered print job stores data indicating that the job type is print, data regarding the job, data regarding the print mode, and image data of the image to be printed. That is, status information is stored in the USB memory 30 in association with the job. Here, as the job status information, information that has not been printed yet (for example, when a job is directly registered in the USB memory 30 from the PC 20 or the like), that is, unprocessed information, that is, unprocessed information, There is information indicating that the job has been interrupted, that is, interrupt information, information indicating that the execution of printing has been completed, that is, processed information. In this execution example, along with the job status information, the time information at which the status information is recorded is also stored in the USB memory 30 in association with the job. For example, in the case of “unprocessed” information, this time information is the time when the job is registered in the USB memory 30. Similarly, when the information is “suspended”, it is the time when the information “suspended” is recorded, but in this case, the time when the suspension was made may be used. Record as.

  The operator attaches (inserts) the USB memory 30 in which a plurality of print jobs are registered into the USB port 11 of the MFP (for example, 10a) that the job is to be executed. When the MFP detects that the USB memory 30 has been inserted (YES in S601), the MFP checks the contents of the USB memory 30 (S602). As a result of the investigation, if the number of jobs in the USB memory 30 is zero, the process ends. If there is even one job, the process proceeds to the next step (S604).

  In step S604, as initialization, first, the next execution candidate job that is a candidate for executing a print job is not included, and the first job is selected from a plurality of jobs. In S605, the status information, that is, status information of the selected job (hereinafter also referred to as a selected job) is checked. In other words, the status information recorded in the USB memory 30 in association with the job is read, and the selected job status is determined as whether the selected job is an interrupted job, an unprocessed job, or a processed job. Identify if there is.

  If the status of the selected job is interrupted in S605, it is checked in S606 whether there is a next execution candidate job. If there is no next execution candidate job, the selected job is set as the next execution candidate job (S609). On the other hand, if there is a next execution candidate job, it is determined whether or not the status of the next execution candidate job is “suspended” (S607). If the next execution candidate job is not a “suspended” job, the selected job is set as the next execution candidate job (S609). With this processing, when there are unprocessed jobs and suspended jobs in the USB memory 30, the execution order is determined so that the suspended jobs are executed preferentially (first), and the jobs are executed. Like to do. On the other hand, if the next execution candidate job is a “suspended” job, the time information storing the “suspended” status information of the next execution candidate job, that is, the suspended time information, and the “suspended” status of the selected job The time information in which the information is stored, that is, the interruption time information is compared, and it is determined whether the time information of the selected job is more recent (closer to the current time) than the next execution candidate job (S608). If the selected job is closest, the selected job is set as the next execution candidate job (S609), and if the next execution candidate job is closest, the next execution candidate job is left as it is. In S613, it is determined whether or not all the jobs in the USB memory 30 have been checked. If all the jobs have not been checked, the next job is selected (S614), and the process proceeds to S605. Return.

  If it is determined in S605 that the selected job is in the unprocessed state, it is checked in S610 whether there is a next execution candidate job. If there is no next execution candidate job, the selected job is set as the next execution candidate job (S609). On the other hand, if there is a next execution candidate job, it is determined whether or not the state of the next execution candidate job is “suspended” (S611). If the next execution candidate job is a “suspended” job, the process advances to step S613. With this processing, when an unprocessed job and a suspended job exist in the USB memory 30, the suspended job is executed preferentially (first). On the other hand, if the next execution candidate job is not an “interrupted” job, the next execution candidate job is an “unprocessed” job in this execution example. Comparing the stored time information with the time information storing the “unprocessed” status information of the selected job, the selected job has the latest time information (depending on the current time) than the next execution candidate job. It is determined whether or not (S612). If the selected job is closest, the selected job is set as the next execution candidate job (S609), and if the next execution candidate job is closest, the next execution candidate job is left as it is. In S613, it is determined whether or not all the jobs in the USB memory 30 have been checked. If all the jobs have not been checked, the next job is selected (S614), and the process proceeds to S605. Return.

  If the status of the selected job is already processed in the identification in S605, the process proceeds to S613.

  Next, if it is determined in S613 that all jobs have been examined, it is determined whether there is a next execution candidate job (S615). If there is no next execution candidate job, the process ends. The job is read from the USB memory 30 (S616), the read job is executed (S617), and the status information recorded in association with the executed job is stored as “processed” in the USB memory 30 (S618). , The process returns to S603.

As described above, in this execution example, when a plurality of print jobs are registered in the USB memory 30, priority is given to jobs executed from among the plurality of jobs by the job execution order determination unit as in S604 to S614. The order (order of execution) is determined, and the job is executed with the order based on the order. In this execution example, in steps S604 to S614, the next execution job is determined and the job is executed, and further the next job is determined. However, priorities of all jobs are set in advance. After that, the job may be executed. In any case, the concept of priority to execute from multiple jobs is:
-Execute suspended jobs over unprocessed jobs.
If there are a plurality of suspended jobs, the job whose suspended time is the latest (closer to the current time, in other words, the elapsed time from the suspended time is short) is executed with priority.
Similarly, when there are a plurality of unprocessed jobs, the job with the latest registration time of the unprocessed job is executed with priority.

  In this execution example, all unprocessed jobs and suspended jobs are configured to be executed. However, as a first modification, before executing the job of S617, the job is executed. The operator may be inquired whether or not to do so. In this case, in order to make an inquiry to the operator, together with the status information of the job to be executed to the operation unit 12, data indicating the job type (data indicating print if it is a print job), data relating to the job (job name) And file name), print mode data, a screen that prompts the operator whether to execute it, and operation keys, and whether to execute the job according to the operator's selection. It is sufficient to perform the control. At this time, “not processed” is assigned as status information to the job not to be executed, and the same processing as the “processed” job in FIG. 8 is performed, and after “NO” in S615, the status “not processed” is set. Information may be rewritten to “unprocessed” state information.

  In this execution example, all unprocessed jobs and suspended jobs are configured to execute the job. However, as a second modification, the time information in which the status information is recorded is the current time information. Whether or not the job is to be executed may be controlled based on whether or not a predetermined time or more has elapsed from the time, that is, the time interval between these two times. If a predetermined time or more has passed from the time information when the status information is recorded to the current time, that is, if the time interval between two times is more than a predetermined time, the job is not executed and the predetermined time The job may be configured to be executed when not separated from each other. More specifically, in this execution example, in the case of a suspended job, a suspended job that has passed for a certain period of time after the suspension is likely to be an unnecessary job for the operator. Do not execute the job. Similarly, even for an unprocessed job, a job that has been stored in the USB memory for a predetermined time or more is likely to be a job that is not immediately necessary, such as a job that the operator is simply saving. In addition, an unprocessed job that has passed a predetermined time does not execute the job.

  It should be noted that only one of the above-described modification examples 1 and 2 may be applied to this execution example, but both may be applied together. That is, only when the time information has passed a predetermined time or more, it is possible to confirm whether or not to execute the job, and to execute the job without confirming if it is within the predetermined time.

  As a matter of course, the PC 20 constituting the system according to the embodiment of the present invention can execute a job management application program capable of recording, reading, and updating job data in the USB memory 30.
