JP5690691B2 - Image forming apparatus and job control program - Google Patents

Description

  The present invention relates to an image forming apparatus and a job control program that enable smooth execution of jobs.

In image forming apparatuses such as copiers and printers, jobs such as scanned document image data and received print data are spooled in memory temporarily and output at a predetermined timing, thereby making output processing more efficient and smooth. We are trying to make it.
For this reason, when trying to process many jobs at the same time, the memory capacity may be exceeded and delays and interruptions may occur, so an upper limit value is set for the number of jobs that can be executed simultaneously. Job execution is restricted.
In addition, Patent Document 1 discloses a job spool control technique for controlling the upper limit value of the number of jobs simultaneously executed based on priority.
According to this job spool control, the upper limit value of the simultaneous execution number of jobs can be dynamically changed according to the urgency level of the job, the executor, or the operating rate of the CPU. It is also possible to cope with processing and perform efficient printing processing.

JP 2007-164481 A

However, the above-described job spool control involves cumbersome processing such as setting the priority for each job and determining the priority between jobs.
In addition, since the control is performed for the entire job regardless of the job type, the above-described job spool control cannot be applied as it is to an MFP or the like having a specification in which an upper limit value is defined for each function. This also causes the following problems.

That is, depending on the user, the execution frequency of the job for each function varies depending on the time zone, day of the week, etc., and there are cases where a certain usage tendency occurs.
For example, in the case of the FAX function, there are many cases where companies and the like collectively transmit and receive at night, and conversely, there are few cases where other functions such as copying and printing are used at night. The same is true for company holidays.
In addition, there are companies that shift their working hours on Saturdays and Sundays due to the cheaper telephone charges and electricity charges, and some users may have a certain tendency for each day of the week.
However, in the above-described job spool control, control is performed for the entire job regardless of the job type. Therefore, when the user environment does not match the MFP specification, it can be handled flexibly and appropriately. I couldn't.

  The present invention has been proposed in order to solve the above-described problems of the conventional technology. By changing the upper limit value of the number of jobs simultaneously executed for each function according to a schedule, the present invention can be used. An object of the present invention is to provide an image forming apparatus and a job control program that can execute a smooth job suitable for an aspect and a use environment.

  In order to achieve the above object, the image forming apparatus according to the present invention includes a job control unit configured to limit job execution when the number of jobs simultaneously executed for each function reaches an upper limit value, and the upper limit according to a specified schedule. And an upper limit changing means for changing the value.

  Further, the job control program of the present invention causes the computer of the image forming apparatus to execute job control when a job execution limit for each function reaches an upper limit, and according to a specified schedule. The upper limit value changing means for changing the upper limit value functions.

  According to the image forming apparatus and the job control program of the present invention, it is possible to execute a smooth job suitable for a user's usage mode and usage environment.

It is a figure for demonstrating the schedule preparation method regarding time slot | zone switching. It is a figure for demonstrating the schedule preparation method regarding a day change. 5 is a flowchart illustrating a control operation in a job control unit.

(Image forming device)
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of an image forming apparatus (MFP 1) according to the embodiment of the present invention.
As shown in FIG. 1, the MFP 1 includes a central processing unit (CPU) 90 as a main control unit, and also includes a read only memory (ROM) 91 and a random access memory (RAM) 92.
The ROM 91 stores a job control program for causing the CPU 90 to execute a job. The ROM 91 stores a program for causing the CPU 90 to execute job processing for each function such as copy, printer, fax (FAX), and PC transmission, and each function is implemented by reading this program. Can do.
The RAM 92 is a memory used as a work area (work area) for temporarily spooling data when the CPU 90 executes these programs.

  As shown in FIG. 1, the MFP 1 includes a document reading unit 10, a communication interface 11, an operation display unit 12, a job input unit 13, an image processing unit 14, an output unit 15, a job control unit 16, and a schedule unit 17.

The document reading unit 10 is a so-called scanner, and acquires image data by reading a document set on a document tray (not shown) according to a copy operation or the like by the operation display unit 12. The document reading unit 10 outputs the acquired image data to the image processing unit 14.
The communication interface 11 is connected to a telephone line, a LAN, or the like, and transmits / receives print data and FAX data to / from an external apparatus such as a personal computer or a FAX apparatus (not shown).

The operation display unit 12 is arranged on the upper outer periphery of the MFP 1 main body (not shown), and performs various input operations by the user of the MFP 1 and displays various screens to the user.
For example, as shown in FIG. 2, the operation display unit 12 includes an operation unit 121 that receives an operation instruction from a user, and a display unit 122 that displays information to the user.
The operation unit 121 can perform various settings related to image output and input operations for starting image processing. A function selection key K1 for selecting execution of a job such as copy, scanner, print, and fax, and print Numeric keypad K2 used for inputting numbers such as the number of copies and the number of copies, start key K3 for starting job execution after the setting is completed, clear key K4 for canceling various settings immediately before via the operation unit 121, start A stop key K5 for canceling the job that has been executed, and a reset key K6 for canceling all the settings and returning to the initial settings.

The display unit 122 is composed of a known liquid crystal display panel, and displays the operation status of the MFP 1, execution results, various setting values input via the operation unit 121, messages to the user, and the like.
In addition, the display unit 122 has a touch panel function that accepts a selection operation, and can accept input of various setting values according to various operation screens.
For example, the display unit 122 can display a “job limit number setting” screen P1 and a “function-specific job management number setting” screen P2, and by touching various keys displayed on these screens, the job can be displayed. It is possible to create a schedule for changing the upper limit value for each function of the number of concurrent executions depending on the time of day or day of the week.
Note that the schedule creation method using the “job limit number setting” screen P1 and the “function-specific job management number setting” screen P2 will be described in detail later in “Schedule creation method”.

The job input unit 13 inputs image data read by the document reading unit 10, print data received via the communication interface 11, job data such as FAX data, and outputs the job data to the image processing unit 14.
The image processing unit 14 interprets job data input from the job input unit 13 and performs necessary image processing. For example, color conversion processing, density correction processing, halftone processing, and the like are performed on a print target job.
The image processing unit 14 outputs the job subjected to the image processing to the output unit 15.
The output unit 15 outputs images and data obtained through the job processing.
For example, it corresponds to a print engine for printing a copy original read by a scanner, an image of received print data, or a FAX image.

Here, the job control unit 16 performs various controls based on the simultaneous execution number of jobs.
For example, when the job control unit 16 detects that the simultaneous execution number of jobs has reached a predetermined upper limit value (limit number), the job control unit 16 rejects acceptance of a new job, and displays that fact on the display unit 122. The process of notifying through is performed as a basic control operation (job control means). This prevents memory overwork.

In addition to the basic control described above, the job control unit 16 performs schedule control for changing the upper limit value of the simultaneous execution number of jobs according to a time zone and a day of the week.
Here, the number of guaranteed jobs and the number of shared jobs that constitute the upper limit value of the simultaneous execution number of jobs is set, and schedule control is performed to change the upper limit value substantially by changing the guaranteed job number according to the time zone and day of the week. Do.
Therefore, the job control unit 16 constitutes a functional block including a guaranteed job number setting unit 161, a shared job number setting unit 162, a schedule creation unit 163, and an upper limit value changing unit 164.

The guaranteed job number setting unit 161 sets the guaranteed job number guaranteed for each function as the number of jobs that can be executed simultaneously.
The number set as the guaranteed job number means that resources such as memory that can be used for the function are guaranteed in the system. That is, it indicates the number of concurrent executions of a job that is guaranteed to be executed without being used by other functions.
In the MFP 1 of the present embodiment, the guaranteed number of jobs can be set for each of copying, PC transmission, printing, FAX transmission, and FAX reception.

However, the number of guaranteed jobs is limited so that the total value for each function is below a certain allowable value. This is because resources such as memory for spooling jobs are limited.
For example, when the allowable value is 470 jobs due to the memory capacity, the number of guaranteed jobs is as follows: copy: 10 jobs, PC transmission: 10 jobs, print: 50 jobs, FAX transmission: 200 jobs, FAX reception: Assuming 100 jobs, the total value is 370 jobs (<470 jobs) and can be set.
The number of guaranteed jobs can be set in advance at the time of manufacturing, and can be set by the user via the communication interface 11 or the operation display unit 12. Further, in an MFP or the like for which an upper limit value is set in the specification, each upper limit value can be set as an initial value of the guaranteed job number.

The shared job number setting unit 162 sets the number of shared jobs that can be commonly assigned to each function as the number of jobs that can be executed simultaneously.
Specifically, a value obtained by subtracting the total number of guaranteed jobs from the allowable value is set as the number of shared jobs.
In the above example, since the allowable value is 470 jobs and the total number of guaranteed jobs is 370 jobs, the remaining 100 jobs (= 470-370) are set as the number of shared jobs.
That is, the value obtained by subtracting the guaranteed job number assigned by each function from the total number of simultaneously executable jobs that can be executed when resources such as memory are used to the maximum is the “shared job number”.

The schedule creation unit 163 creates a schedule related to the upper limit value of the simultaneous execution number of jobs according to the input operation. Specifically, a schedule in which an upper limit value is set for each time zone and day of the week is created.
Here, the “upper limit value” is determined based on the number of guaranteed jobs and the number of shared jobs regarding the function of the job type.
For example, when the guaranteed number of jobs for FAX transmission is set to 100 jobs and the number of shared jobs is set to 200 jobs, the upper limit value for FAX transmission jobs is 300 jobs (= 100 + 200) at the maximum. In other words, the number of shared jobs is not used when the number of concurrent executions of other running jobs is less than or equal to the number of guaranteed jobs. In this case, the total value of the number of shared jobs and the number of guaranteed jobs is the upper limit (maximum value). )
However, if the number of concurrent executions of other running jobs exceeds the guaranteed number of jobs, the excess is allocated from the number of shared jobs. For this reason, the limit number when this excess is set to α jobs is (300−α) jobs.
Therefore, in the present embodiment, the schedule creation unit 163 creates a schedule related to the guaranteed job number and the shared job number according to the input operation. A specific schedule creation method will be described later.

The upper limit changing unit 164 changes the upper limit of the number of jobs simultaneously executed according to the created schedule.
For example, the upper limit value of the simultaneous copy execution number in the daytime is w jobs, and the upper limit value of the simultaneous copy execution number in the night is x jobs. The upper limit value can be changed for each job type according to the time zone. .
Also, the upper limit value of the simultaneous execution number of prints on weekdays is y jobs, and the upper limit value of the simultaneous execution number of prints on holidays is z job, so that the upper limit value can be changed for each job type depending on the day of the week.

  The calendar unit 17 includes a clock circuit that operates independently from a battery or the like, and always measures the year, month, date, hour / minute / second, day of the week, and the like. In the present embodiment, when a job is executed, information such as the current date and time, day of the week, etc. is transferred in response to a request from the job control unit 16.

(How to create a schedule)
Next, a schedule creation method will be described with reference to the drawings.
First, a schedule creation method relating to time zone switching will be described.
FIG. 3 is a diagram for explaining a schedule creation method related to time zone switching.

For example, to set the start time at 22:00, select the “start” “hour” key F11 and then press the plus key F15 or the minus key F16 to set the “start” “hour” to “22”. (Iii).
When the end time is set to 9:00, the “end” “hour” key F12 is selected and then the plus key F15 or the minus key F16 is pressed to set the “end” “hour” to “9”. (Iv).
Then, the confirmation button F17 is pressed (v). By this operation, the “function-based job management number setting” screen P2 (FIG. 3D) is displayed on the display unit 122.

As shown in FIG. 3D, the copy key f1, the PC transmission key f2, the print key f3, the FAX transmission key f4, the FAX reception key f5, and the shared key f6 are displayed on the “job management number setting by function” screen P2. , Plus key f7, minus key f8, and confirm button f9 are displayed.
On the same screen, boxes P1 to P5 for displaying the set value of the guaranteed job number for each function and the box P6 for displaying the set value of the number of shared jobs are displayed.
As shown in FIG. 3D, the current set value of the number of guaranteed jobs is copy: 10 jobs, PC transmission: 10 jobs, print: 50 jobs, FAX transmission: 200 jobs, FAX reception: 100 jobs. Assume that 100 jobs are set as the current setting value of the number of shared jobs.

Here, as shown in FIG. 3 (e), after selecting the FAX transmission key f4 (vi), if the minus key f8 is kept pressed and the number of guaranteed jobs for FAX transmission is changed from 200 to 100 (vii), Since the guaranteed number of jobs for FAX transmission is -100, the decrease 100 is added to the number of shared jobs to be 200 (viii).
Next, as shown in FIG. 3 (f), after selecting the print key f3 (ix), if the plus key f7 is kept pressed to change the number of guaranteed jobs for printing from 50 to 250 (x), the number of shared jobs Is -200, and the guaranteed number of jobs for printing is 250 (xi).
Then, by selecting the confirm button f9, the guaranteed job number and the shared job number are confirmed and updated to the changed values (xii).

Next, a schedule creation method related to day of the week switching will be described.
FIG. 4 is a diagram for explaining a schedule creation method regarding day switching.
As shown in FIG. 4A, a “job limit number setting” screen P1 is used as a setting screen for creating a schedule.
On the “job limit number setting” screen P1, a time zone switching key F1, a day switching key F2, a plus (+) key F3, a minus (−) key F4, and a confirmation button F5 are displayed.

When creating a schedule related to day switching, as shown in FIG. 4B, first, the day switching key F2 is selected, and the setting is changed from OFF to ON by pressing the plus key F3 or the minus key F4. In (i), the confirmation button F5 is pressed (ii). By this operation, the “day change 1” screen P12 (FIG. 4C) is displayed on the display unit 122.
A plurality of day switching keys F2 can be provided. In this way, it is possible to set a plurality of days designation patterns. Hereinafter, an example in which the day switching 1 key F2 is selected will be described.

As shown in FIG. 4C, on the “day switching 1” screen P12, a key F21 for setting the start day of the week, a key F22 for setting the end day of the week, a plus key F23, a minus key F24, And the confirmation button F25 is displayed.
For example, when setting the start day of the week as Saturday, after selecting “start”, the user presses the plus key F23 or the minus key F24 to set the start day of the week to “SAT” (iii).
When setting the end day of the week to Sunday, after selecting “end”, the user presses the plus key F23 or the minus key F24 to set the end day of the week to “SUN” (iv).
Then, the confirmation button F25 is pressed (v). With this operation, the setting relating to the day of the week is completed, and the “job management number setting by function” screen P2 (FIG. 4D) is displayed on the display unit 122.

As shown in FIG. 4D, a copy key f1, a PC transmission key f2, a print key f3, a FAX transmission key f4, a FAX reception key f5, and a shared key f6 are displayed on the “function-specific job management number setting” screen P2. , Plus key f7, minus key f8, and confirm button f9 are displayed.
On the same screen, boxes P1 to P5 for displaying the set value of the guaranteed job number for each function and the box P6 for displaying the set value of the number of shared jobs are displayed.
As shown in FIG. 4D, the current set value of the guaranteed number of jobs is copy: 10 jobs, PC transmission: 10 jobs, print: 50 jobs, FAX transmission: 200 jobs, FAX reception: 100 jobs. Assume that 100 jobs are set as the current setting value of the number of shared jobs.

Here, as shown in FIG. 4 (e), after selecting the FAX transmission key f4 (vi), if the minus key f8 is kept pressed and the number of guaranteed jobs for FAX transmission is changed from 200 to 100 (vii), Since the guaranteed number of jobs for FAX transmission is -100, the decrease 100 is added to the number of shared jobs to be 200 (viii).
Next, as shown in FIG. 4 (f), after selecting the print key f3 (ix), if the plus key f7 is kept pressed to change the number of guaranteed jobs for printing from 50 to 250 (x), the number of shared jobs Is -200, and the guaranteed number of jobs for printing is 250 (xi).
Then, by selecting the confirm button f9, the guaranteed job number and the shared job number are confirmed and updated to the changed values (xii).
In this way, it is possible to easily create an upper limit schedule regarding time zone switching and day switching via a panel operation.
Note that the job control unit 16 sets the schedule creation completed state to “ON”, and sets the other states to “OFF” to hold the setting / non-setting of the schedule in an identifiable manner.

Next, the control operation in the job control unit will be described.
FIG. 5 is a flowchart showing a control operation in the job control unit.
As shown in FIG. 5, the job control unit 16 confirms the type of the accepted job (step 1), and confirms the number of jobs being executed (including unexecuted) for that type (step 2).
Here, the job control unit 16 confirms ON / OFF of time zone switching (step 3). That is, the setting / non-setting of the above-described “schedule for time zone switching” is determined.
If time zone switching is ON, the current time is confirmed (step 4). Specifically, the job control unit 16 inquires of the calendar unit 17 and acquires the current time.

Then, the limit number (upper limit value) corresponding to the current time is compared with the number of jobs being executed (step 5). Specifically, the job control unit 16 extracts a limit number corresponding to the current time regarding the job type confirmed in step 1 from the schedule, and compares the type with the number of jobs being executed of the same type.
As a result, if the number of jobs being executed is within the limit, the accepted job is executed (step 6).
On the other hand, when the number of jobs being executed exceeds the limit number, the job control unit 16 rejects acceptance of the job (step 7). In this case, the job control unit 16 informs the operation display unit 12 that the job reception has failed, and the display unit 122 displays an error indicating the fact.

If the time zone switching is OFF in step 3, the job control unit 16 confirms ON / OFF of the day switching (step 8). That is, the setting / non-setting of the above-mentioned “schedule for day switching” is determined.
If the day of week switching is ON, the job control unit 16 inquires of the calendar unit 17 and confirms the current day of the week (step 9).
Then, the limit number (upper limit value) corresponding to the current day of the week is compared with the number of jobs being executed (step 10). Specifically, the job control unit 16 extracts a limit number corresponding to the current day of the week regarding the job type confirmed in step 1 from the schedule, and compares the type with the number of jobs being executed of the same type.
As a result, if the number of jobs being executed is within the limit, the accepted job is executed (step 6). On the other hand, if the number of jobs being executed exceeds the limit, the job control unit 16 rejects acceptance of the job (step 7).

If the day of week switching is OFF in step 8, the basic control number is compared with the number of jobs being executed (step 11). Specifically, the job control unit 16 takes out the initial value or standard value of the limit number related to the job type confirmed in step 1, and compares the type with the number of jobs being executed of the same type.
As a result, if the number of jobs being executed is within the limit, the accepted job is executed (step 6). On the other hand, if the number of jobs being executed exceeds the limit, the job control unit 16 rejects acceptance of the job (step 7).

As described above, according to the image forming apparatus (MFP 1) according to the present embodiment, the upper limit value of the simultaneous execution number of jobs can be changed for each function according to a schedule such as a time zone and a day of the week.
For this reason, it can respond flexibly to a user's usage mode and usage environment, and can execute a job efficiently and smoothly.
The schedule can be easily set or changed through a panel operation. For this reason, there is an effect excellent in operability and convenience.

The job control function, guaranteed job number setting function, shared job number setting function, schedule creation function, and upper limit change function of the computer (image forming apparatus) in the above embodiment are stored in storage means (for example, ROM, hard disk, etc.). This is realized by the job control program.
The job control program is read by a computer control means (such as a CPU), thereby sending a command to each component of the computer, and performing job control such as the above-described schedule change of the upper limit value of the number of jobs simultaneously executed.
As a result, the above functions are realized by cooperation between the job control program that is software and each component of the computer (image forming apparatus) that is hardware resource.

The external storage device is a memory expansion device that incorporates a recording medium such as a CD-ROM (Compact Disc-Read Only Memory) and is externally connected to the image forming apparatus. On the other hand, the portable recording medium is a recording medium that can be mounted on a recording medium driving device (drive device) and is portable, and refers to, for example, a flexible disk, a memory card, a magneto-optical disk, and the like.

Then, the program recorded on the recording medium is loaded into the RAM of the computer and executed by the CPU. By this execution, each function of the above-described embodiment is realized.
Further, when a job control program is loaded by a computer, these programs held by another computer can be downloaded to its own RAM or external storage device using a communication line. This downloaded program is also executed by the CPU, and realizes each function in the image forming apparatus of the embodiment.

  As described above, according to the image forming apparatus (MFP 1) and the job control program of the present embodiment, the upper limit value of the simultaneous execution number of jobs is set or changed based on a schedule such as a time zone and a day of the week. Therefore, it is possible to execute a smooth job suitable for the usage mode and usage environment of the user.
