  By the way, in the image forming apparatus that processes the print jobs set by the user in the order received, when the user sets the print job with the operation unit of the image forming apparatus, the set job is expected to be executed immediately, There is a case of waiting in front of the image forming apparatus until the processing of the set job is completed.

In this case, if another print job being processed requires a long time, the user will wait for a long time in front of the image forming apparatus.
The present invention has been completed based on the above circumstances, and an object thereof is to provide an image processing apparatus that improves the convenience of a user who sets a job by operating an operation means.

The first invention is an image processing apparatus, comprising: an operating means for setting a job for processing an image; a receiving means for receiving a job set by the operating means; and a job received by the receiving means Execution means to be executed and processing to be executed before the execution means can execute a new job when the execution means is executing another job when a new job is set by the operation means Grasping means for grasping the amount, and the accepting means accepts the new job when the executing means is executing another job when a new job is set by the operating means. No is determined based on the processing amount grasped by the grasping means.
According to the present invention, for example, when it is determined that a new job is not accepted when the processing amount is larger than a predetermined amount, if the user does not accept the job, “until the execution means can execute the new job” It can be seen that the “processing amount to be processed” is large.
Or conversely, even if it is determined that a new job is accepted when the processing amount is larger than the predetermined amount, the user can know that the processing amount is large if the job is accepted.
The user does not have to wait for a long time in front of the operation means because it is understood that the new job set by the user is not executed immediately when the processing amount is large.
Therefore, according to the present invention, the convenience of the user who sets the job by operating the operation means is improved.

A plurality of control means for inputting and outputting images, wherein the grasping means is configured to cause the determination means to input the input / output means used by the first execution means to input the second execution. The input / output means used by the first execution means for outputting the image is the second execution common to either the input / output means used for inputting the image by the means or the input / output means used for outputting the image. When it is determined that neither the input / output unit used for inputting an image nor the input / output unit used for outputting an image is common, the first execution unit finishes inputting the image as the processing amount. You To grasp the amount of processing to process up to.
According to the present invention, the execution of a new job can be started at an earlier timing compared to the case where the first execution means grasps the processing amount to be processed before the image output is completed.

A sixth invention is the image processing apparatus according to the fifth invention, wherein when the new job is accepted by the accepting means, before the first execution means is used by the judging means to output an image. When it is determined that the input / output means used for inputting the image is not common between the entry output means and the second execution means, the second execution means inputs the image and the first execution means. An image processing apparatus that executes in parallel with the output of an image by the computer.
According to the present invention, a job can be executed efficiently.

A seventh invention is the image processing apparatus of the second invention, wherein when the processing amount is equal to or greater than the predetermined amount, an authentication information input means for a user to input authentication information; Authenticating means for authenticating, and the accepting means accepts the new job regardless of the processing amount when the authentication by the authenticating means is successful.
As described above, a new job may be accepted for a user who is given authentication information regardless of the processing amount.

An eighth invention is the image processing device of the seventh invention, wherein the authentication information input means requests the user to input the authentication information when the execution means can execute the new job, The execution means executes the new job when authentication information is input by the authentication information input means after the new job can be executed.
If a user who has been given authentication information leaves the image processing apparatus after setting a new job, the new job may be executed while the user is away and the processing result may be viewed by other users. There is.
According to this invention, after the new job can be executed, when the authentication information is input, the new job is executed. Therefore, the user who has input the authentication information can execute the new job by the execution means. By returning to the image processing apparatus and inputting authentication information, the possibility that the processing result will be viewed by other users can be reduced.

The PC print job is a job for printing image data transmitted from a PC connected to the USB interface 43A via a USB cable onto a recording medium. Unlike other jobs, the PC print job is set not on the operation unit 42 of the multifunction machine 1 but on the PC side.

The FAX transmission job is a job in which a document is read by the reading unit 25 to generate image data, and the generated image data is facsimile-transmitted by the facsimile transmission / reception unit 40.
The PC scan job is a job in which an original is read by the reading unit 25 to generate image data, and the generated image data is transmitted to a PC connected to the USB interface 43A via a USB cable.

  The network scan job is a job in which a document is read by the reading unit 25 to generate image data, and the generated image data is transmitted to an external server or the like connected to the network interface 43B via an electric communication line.

The direct print job is a job for reading image data from an external storage device connected to the USB interface 43A, and printing the read image data on a recording medium by the printing unit 41. In the following description, a USB memory will be described as an example of the external storage device.
The scan-to-USB job is a job that generates image data by reading a document by the reading unit 25 and stores the generated image data in a USB memory connected to the USB interface 43A.

(3) Execution means Each type of job is executed by different execution means.
One execution means controls input / output means (hereinafter simply referred to as “input means”) used for image input, input / output means (hereinafter simply referred to as “output means”) used for image output, and these. And a CPU 37 (an example of control means) for inputting and outputting images. The CPU 37 functions as a plurality of control means by controlling the input / output means in different combinations. Thereby, a plurality of execution means are configured.

(4) Job collision Even when any execution means is executing a job (hereinafter referred to as “another job”), the user can execute any one of the execution means including the execution means executing the other job. A new job to be executed can be set.
In this case, there is a possibility that another job and a new job have the same execution means. The common execution means in this embodiment refers to the following cases.

1) When an input unit and an output unit are common to an execution unit that executes another job and an execution unit that executes a new job.
2) The execution means for executing another job and the execution means for executing a new job do not have the same input means, but have the same output means.
3) When the output means of the execution means for executing another job and the input means of the execution means for executing a new job are common.
4) When the input means of the execution means for executing another job and the output means of the execution means for executing a new job are common.

  If the execution means are common, the common execution means is executing another job, so depending on the timing when a new job is set, execution may wait until the execution of the new job is started. Alternatively, there is a case where an execution wait occurs during the execution of a new job. In the present embodiment, waiting for execution of a new job due to another job being executed is called job collision.

  FIG. 2 is a table showing combinations in common execution means. The combinations that are knitted in the figure are combinations that the execution means do not share in this embodiment. Circles in the figure indicate that they are common, and crosses indicate that they are not common.

For example, when the input unit and the output unit are not common, the execution unit is not common.
In addition, in this embodiment, when the input unit is common and the output unit is not common, and when the common input unit is the reading unit 25, the execution unit is not common. The reason will be described below.

  For example, when another job is a job for reading a document placed on the document tray 17 of the ADF 16, a new job for placing and reading a document on the first platen glass 12 is generally read when the ADF 16 is operating. Never set. Therefore, in this case, the reading unit 25 does not compete between another job and a new job.

When another job is a job for reading a document placed on the first platen glass 12, a new job can be set for reading a document placed on the document tray 17 of the ADF 16, but the first platen Since the reading of one original placed on the glass 12 is completed in a relatively short time, even if there is a conflict, it takes only a short time.
For the above reasons, when the common input means is the reading unit 25, the execution means is not common.

  In addition, since the PC print job is set on the PC side, if the PC print job is a new job, the user does not wait in front of the multifunction device 1. Therefore, in this embodiment, only the case where the PC print job is set as another job will be described, and the case where the PC print job is set as a new job is excluded.

  “USB Ca” in the drawing indicates the USB interface 43A to which the USB cable is connected, and “USB memory” indicates the USB interface 43A to which the USB memory is connected. “Network” indicates the network interface 43B. “Facsimile” indicates the facsimile transmission / reception unit 40.

Note 1) in the figure indicates that the PC print job input means (USB Ca) and the PC scan job output means (USB Ca) are common.
Note 2 in the figure indicates that the direct print job input means (USB memory) and the scan to USB job output means (USB memory) are common.

Hereinafter, the cases 1) to 4) described above will be specifically described.
(4-1) A case where an input unit and an output unit are common to an execution unit that executes another job and an execution unit that executes a new job.
When the different job and the new job are the same type of job, the input means is common to the execution means for executing the different job and the execution means for executing the new job, and the output means is also common. Here, a copy job will be described as an example of the same type of job.

  For example, it is assumed that another copy job (hereinafter referred to as “another copy job 1”) is a copy job for copying a document placed on the first platen glass 12. In this case, another document can be placed on the document tray 17 of the ADF 16 while another copy job 1 is being executed. Therefore, another user can set a new copy job (hereinafter referred to as “new copy job 2”) by placing the document on the document tray 17 of the ADF 16 while another copy job 1 is being executed. .

For example, another copy job 1 is a copy job for copying 100 originals placed on the first platen glass 12, and now the reading of the originals is completed and printing is being performed by the printing unit 41. And Assume that another user sets a new copy job 2 when printing 30 sheets out of 100 sheets.
In this case, since reading by another copy job 1 has been completed, reading by the new copy job 2 can be started immediately, but printing by the new copy job 2 is performed by the printing unit 41 that executes another copy job 1. Execution is not started until printing for the remaining 70 sheets is completed, and the user who has set a new copy job 2 waits in front of the multifunction machine.

(4-2) The case where the execution means for executing another job and the execution means for executing a new job do not share the input means but share the output means.
If the type of another job is different from the type of the new job, the execution unit that executes another job and the execution unit that executes the new job may not have the same input unit and may have the same output unit. is there. For example, when another job is a PC print job and a new job is a copy job, the input unit is not common and the output unit is common.

For example, it is assumed that another PC print job is a job for printing 100 pieces of image data. It is assumed that another user sets a new copy job when printing 30 sheets out of 100 sheets.
In this case, the printing by the new copy job is not started until the printing of the remaining 70 sheets by the printing unit 41 that executes another PC print job is completed, and the user who has set the new copy job is combined. You will be waiting in front of the plane.

(4-3) The output means of the execution means for executing another job is common with the input means of the execution means for executing a new job.
When the type of another job is different from the type of the new job, the output unit of the execution unit that executes another job may be in common with the input unit of the execution unit that executes the new job. For example, when another job is a scan-to-USB job and a new job is a direct print job, the output means (USB memory) of the other job and the input means (USB memory) of the new job are common. Become.

  For example, it is assumed that another scan to USB job is a job that reads 100 originals and writes image data for each original to the first USB memory. Then, when 30 sheets of 100 originals are read and image data is written, another user connects a second USB memory to another USB port and sets a new direct print job. .

  In this case, assuming that only one USB memory can be accessed at the same time, reading from the second USB memory by a new direct print job is performed for the remaining 70 originals by the reading unit 25 that executes another scan-to-USB job. The execution is not started until the reading of the image data and the writing of the remaining 70 image data to the first USB memory by the USB interface 43A are completed. For this reason, a user who has set a new direct print job waits in front of the multifunction peripheral.

(4-4) The case where the input means of the execution means for executing another job is the same as the output means of the execution means for executing a new job.
Contrary to the above-described example, when another job is a direct print job and a new job is a scan to USB job, another job input unit (USB memory) and a new job output unit (USB memory) ) In common.

  For example, it is assumed that another direct print job is a job that reads and prints image data for 100 sheets from the second USB memory one image data at a time. Assume that when 30 users out of 100 images are read and printed, another user connects the first USB memory to another USB port and sets a new scan-to-USB job.

  In this case, writing to the first USB memory by a new scan to USB job is performed by reading the remaining 70 sheets of image data from the second USB memory by the USB interface 43A for executing another direct print job and the printing unit. The execution is not started until the printing of the remaining 69 sheets of image data by 41 is completed. For this reason, a user who has set a new scan to USB job will wait in front of the multifunction peripheral.

  Here, the number of prints of the printing unit 41 is 69. When the last one of the image data is printed, the USB interface 43A receives the image data from the second USB memory by another direct print job. This is because reading has been completed. If the reading of the image data from the second USB memory has been completed, the writing of the image data to the first USB memory by a new scan to USB job can be started. There is no need to wait for printing to finish.

(5) Process Overview of Multifunction Device 1 As described above, when a job collides, the user waits in front of the multifunction device due to the execution of a new job.
Therefore, in the present embodiment, when the execution unit is executing another job when a new job is set, the execution unit can execute the new job whether or not to accept a new job. It is determined based on the processing amount to be processed.

Here, “until the execution means can execute a new job” means that a new job can be executed without colliding with another job, and the above-described 1) to 3) In this case, until another job output unit finishes executing the other job, in other words, until another job ends.
In the case of 4) described above, this is until the input unit of another job finishes executing the other job. In this case, a new job can be executed before the execution of another job is completed.

In the case of 1) to 3) described above, “the processing amount that is executed before the execution unit can execute a new job” is the same as the input unit of another job when a new job is set. It depends on whether or not another job has been executed.
If another job input unit has not finished executing the other job, the remaining processing amount that the input unit processes for the other job and another job output unit for the other job This is the total of the remaining processing amount to be processed (if the output unit of another job has not started execution of the other job, the total processing amount that the output unit will subsequently process for the other job).
On the other hand, when another job input unit has finished executing the other job, the remaining processing amount is processed by the other job output unit for the other job.

  In the case of 4) described above, the remaining processing amount is processed by another job input unit for the other job. However, when the input unit and the output unit execute another job in parallel, this is the total of the processing amount processed by the output unit until the input unit finishes executing the other job.

Hereinafter, the process of the multi function device 1 will be described more specifically by taking the case of 1) described above as an example. In the following description, a copy job will be described as an example of the same type of job.
FIG. 3 is a timing chart for explaining the processing of the multifunction machine 1. In the example shown in the figure, another copy job 1 is a copy job for copying 100 originals placed on the first platen glass 12, and is currently being read by the reading unit 25. It is assumed that 1/3 has been read in the long side direction. The new copy job 2 is assumed to be a copy job for copying a document placed on the ADF 16.

When a new copy job 2 is set, the multi-function device 1 grasps “the amount of processing to be performed before the execution unit can execute a new job”. That is, the multifunction device 1 grasps the total of the remaining processing amount that the reading unit 25 processes for another copy job 1 and the total processing amount that the printing unit 41 will process for another copy job 1 from now on.
In the present embodiment, it is assumed that the processing amount of the reading unit 25 is grasped by the width of the document in the sub-scanning direction. Accordingly, the remaining processing amount processed by the reading unit 25 is grasped as the width in the sub-scanning direction of the area of the document being read that has not yet been read, that is, the width of 2/3 in the long side direction of the document. Note that the processing amount of the reading unit 25 may be grasped by the area of the document.

  In the present embodiment, the processing amount of the printing unit 41 is grasped by the amount of data to be printed. In the illustrated example, since the printing unit 41 has not started execution of another copy job 1, the remaining processing amount processed by the printing unit 41 is the data amount of image data generated by the reading unit 25 reading a document × Grasped as 100

As described above, in this embodiment, whether or not to accept a new copy job 2 is determined based on the grasped processing amount, but is not determined directly from the grasped processing amount, but by another copy job 1. The remaining time until the end of printing is estimated from the processing amount, and is determined based on the estimated remaining time (hereinafter referred to as “estimated time”).
For example, the time required for the reading unit 25 to read the remaining 2/3 of the original is estimated from the reading conditions and the like, and the standard required for the printing unit 41 to print one piece of image data generated by reading the original The time required for printing is estimated by multiplying the time required by 100, and the total of these times is taken as the estimated time.

  By the way, when the reading of the original and the printing can be executed in parallel, the printing can be started without waiting for the completion of the reading of the original. If printing can be started without waiting for the completion of reading of the original, the estimated time can be shortened by the time from the start of printing to the end of reading of the original. In other words, in this embodiment, when the input unit and the output unit execute one job in parallel, the processing amount excluding the processing amount processed by the input unit while executing the job in parallel Based on the above, it is determined whether or not to accept a new copy job 2.

  The multifunction device 1 determines that a new copy job 2 is accepted when the estimated time is less than a predetermined time (an example of a predetermined amount), and determines not to be accepted when the estimated time is longer than the predetermined time. If the predetermined time is 1 minute, the estimated time is 30 seconds in the illustrated example, which is less than 1 minute, so it is determined that a new copy job 2 is accepted. Whether the predetermined time is 1 minute is a design item that can be selected as appropriate.

  Incidentally, although the estimated time is 30 seconds, the reading unit 25 finishes reading by the copy job 1 at a time before that. The multi-function device 1 can execute the reading of the original document by the reading unit 25 and the printing by the printing unit 41 in parallel. When the multi-function device 1 completes the reading by the copy job 1, the printing by the copy job 1 is completed. Reading by the copy job 2 is started without waiting.

  FIG. 4 is another timing chart for explaining the processing of the multifunction machine 1. In the example shown in the figure, another copy job 1 is a copy job for copying 100 originals placed on the original tray 17 of the ADF 16, and currently reading by the reading unit 25 has been completed. Assume that the printing unit 41 has finished printing up to 30 of 100 sheets.

It is assumed that the new copy job 2 is a copy job for reading a document placed on the first platen glass.
The “processing amount processed until the execution unit can execute a new job” is grasped as the remaining processing amount processed by the output unit (printing unit 41) of another copy job 1. That is, it is grasped as data amount of image data × 70.
In the example shown in the figure, the estimated time is 30 seconds, which is less than 1 minute, so it is determined that a new copy job 2 is accepted. When a new copy job 2 is received, reading by the copy job 1 has already been completed, so the multifunction device 1 immediately starts reading by the copy job 2.

FIG. 5 is another timing chart for explaining the processing of the multifunction machine 1. In the illustrated example, when a new copy job 2 is set, the multifunction device 1 is executing printing by another copy job 1 and the estimated time is 1 minute 30 seconds. Since the estimated time is 1 minute or longer, the multifunction device 1 determines not to accept the copy job 2.
If the copy job 2 is not accepted, the multifunction device 1 notifies the user that the copy job is not accepted. In the present embodiment, notification is made by displaying a message to that effect on the LCD 42B of the operation unit 42.

  FIG. 6 is a schematic diagram showing the operation unit 42. As shown in the figure, the multi-function device 1 displays a message “Previous printing takes time. Job not accepted” on the LCD 42B. Thereby, the user can know that the copy was not accepted. Note that notification to the user that the copy job is not accepted may be performed by other methods such as voice guidance.

FIG. 7 is another timing chart for explaining the processing of the multifunction machine 1. In the example shown in the figure, when a new copy job 2 is set, the multifunction device 1 is executing reading by another copy job 1. In the illustrated example, the estimated time is 1 minute 30 seconds.
If a new copy job 2 is received unconditionally, if another copy job 1 requires a long time, the user who has set the new copy job 2 is the multifunction device. There is a possibility that the user will wait for a long time before and leave the MFP 1 halfway without waiting. When the user leaves the multifunction device 1, a new copy job 2 is executed while the user is away from the multifunction device 1, and the print result may be viewed by other users. If the estimated time is long (1 minute or longer), it is difficult to cause a new copy job 2 to be accepted, which is desirable from the viewpoint of security.

  However, even if the estimated time is long, if there is no risk that the print result will be viewed by other users, some users may find it more convenient to accept a new copy job 2 There is also. For example, a new copy job 2 may not be accepted, and a new copy job 2 may be set first by another user while the user is away from the multifunction device 1. is there.

Therefore, even if the estimated time exceeds 1 minute, if the user who has set a new copy job 2 can use the security function, the multifunction device 1 exceptionally accepts the new copy job 2.
Specifically, the multifunction device 1 displays a message prompting the user to input a user ID and password on the LCD 42B before displaying the above-described message not accepting the copy job. The user ID and password are examples of authentication information.

  When the user inputs the user ID and password, the multifunction device 1 determines whether or not the use of the security function is permitted for the input user ID and password. The multifunction device 1 accepts a new copy job 2 if the use of the security function is permitted. At this time, the multifunction device 1 stores the input user ID and password in association with the new copy job 2.

On the other hand, if the user does not enter the user ID and password, or if the use of the security function is not permitted for the entered user ID and password, a new copy job 2 is not accepted and a copy job is accepted. A message indicating that there is no message is displayed.
When the multifunction device 1 accepts a new copy job 2 because the use of the security function is permitted, the multifunction device 1 starts printing by the new copy job 2 immediately after the printing by another copy job 1 is completed. Instead, the process waits until a user ID and password corresponding to a new copy job 2 are input, and printing is started when the user ID and password are input.

  In this way, it is possible to prevent other users from setting a new copy job 2 first, and to print results while the user who has set a new copy job 2 is away from the multifunction device 1. Can be prevented from being viewed by other users.

(6) Processing of Multifunction Device When a new job is set by the operation unit 42, the multifunction device 1 accepts a new job and starts execution immediately if another job is not being executed.
Further, when another job is being executed when a new job is set by the operation unit 42, the multifunction device 1 executes a new job executing means (referred to as a first execution means) and a new job. It is determined whether or not the execution means for executing the job (referred to as the second execution means) is common, and when it is determined that the execution means is not common (in the case of the combination shown by knitting in FIG. 2), Regardless of the “processing amount to be processed until a new job can be executed”, a new job is received and execution is immediately started.

On the other hand, when it is determined that the first execution unit and the second execution unit are common, the multi function device 1 determines whether to accept a new job based on the processing amount.
Hereinafter, the process of the multifunction machine 1 after determining that the first execution unit and the second execution unit are common will be described.

(6-1) Overall Processing FIG. 8 is a flowchart showing the flow of overall processing of the multifunction peripheral after determining that the first execution means and the second execution means are common. Here, a case where another job and a new job are both copy jobs will be described as an example.

In S101, the CPU 37 obtains an estimated time T until a new copy job can be executed.
In S102, the CPU 37 determines whether or not the estimated time T is less than 1 minute. When the estimated time T is less than 1 minute, the CPU 37 determines to accept a new copy job and proceeds to S103. When the estimated time T is 1 minute or more, the CPU 37 proceeds to S107.
In S103, the CPU 37 accepts a new copy job. Specifically, for example, the CPU 37 adds a new copy job to the job execution list.

In S <b> 104, the CPU 37 immediately reads a document by a new copy job if the reading unit 25 has finished reading by another copy job, and waits for the completion if the reading unit 25 has not finished reading a new copy job. Scan the original.
In S105, the CPU 37 determines whether printing of another copy job is completed at regular time intervals, and proceeds to S106 when printing of another copy job is completed.

In S106, the CPU 37 executes printing by a new copy job.
In S107, the CPU 37 displays a message prompting the user to input authentication information (user ID and password) on the LCD 42B.
In S108, the CPU 37 determines whether authentication information has been input. When the authentication information is not input or when the authentication of the input authentication information fails, the CPU 37 proceeds to S109, and when the authentication information is input and the authentication is successful, the CPU 37 proceeds to S110.

  In S109, the CPU 37 determines whether or not a predetermined standby time has elapsed after prompting for input of authentication information in S108. It is assumed that the CPU 37 waits for a certain period of time after prompting the authentication information to be input in S108, and if the authentication information is not input during that time, the authentication information is not input. This fixed time is the waiting time. The CPU 37 returns to S108 if the standby time has not elapsed, and proceeds to S111 if it has elapsed.

  In S110, it is determined based on the input authentication information whether the user who has input the authentication information is permitted to use the security function. The CPU 37 proceeds to S111 if the user is not permitted to use the security function, and proceeds to S112 if the user is permitted.

In S111, the CPU 37 determines not to accept the copy job, displays the message indicating that the above-mentioned copy is not accepted, and ends the process.
In S112, the CPU 37 accepts a new copy job and executes “copy processing when the security function operates”.

(6-2) Copy processing during operation of security function In S201, the CPU 37 waits for the reading unit 25 to finish reading with another copy job, and executes reading of a document with a new copy job.
In S202, the CPU 37 stores the image data generated by reading the document in S201 in the RAM 39.
In S203, the CPU 37 determines whether or not printing of another copy job is completed at regular time intervals, and proceeds to S204 when printing of another copy job is completed.

In S204, the CPU 37 determines whether or not the “Secure Print” button has been pressed. If the “Secure Print” button has not been pressed, the CPU 37 proceeds to S205. If it has been pressed, the CPU 37 proceeds to S207.
In S205, the CPU 37 determines whether or not the storage time of the image data generated in S201 has elapsed. The CPU 37 stores the image data in the RAM 39 in S202 and then stores the image data for a certain period of time. If the “Secure Print” button is not pressed during that time, the CPU 37 determines that the user does not intend to print the image data. The image data stored in the RAM 39 is erased. This fixed time is the storage time. If the storage time has not elapsed, the CPU 37 returns to S204, and if it has elapsed, the CPU 37 proceeds to S206.

In S206, the CPU 37 deletes the image data from the RAM 39 and ends the process.
In S207, the CPU 37 displays a message prompting the user to input authentication information (user ID and password) on the LCD 42B.
In S208, the CPU 37 determines whether authentication information has been input. If the authentication information is not input or the authentication of the input authentication information fails, the CPU 37 proceeds to S209. If the authentication information is input and the authentication is successful, the CPU 37 proceeds to S211.

In S209, the CPU 37 determines whether or not a predetermined waiting time has elapsed since the “Secure Print” button was pressed in S204. The CPU 37 returns to S208 if the standby time has not elapsed, and proceeds to S210 if it has elapsed.
In S210, the CPU 37 deletes the message displayed on the LCD 42B in S207 and returns to S204.
In S211, the CPU 37 executes printing by a new copy job.

(7) Effects of the Embodiment According to the multifunction device 1 according to the embodiment of the present invention described above, when the “processing amount processed until the execution unit can execute a new job” is larger than a predetermined amount. Decide not to accept new jobs. A user who has set a new job can know that the amount of processing is large because the job is not accepted, and it can be seen that the new job set by himself will not be executed immediately. You don't have to wait a long time in front.
Therefore, according to the multifunction machine 1, the convenience of the user who sets the job by operating the operation unit 42 is improved.

Further, according to the multifunction machine 1, for example, in the case of 1) to 3) described above, the “processing amount processed until the execution unit can execute a new job” is changed after a new job is set. The processing amount processed by the execution means until the job is completed is grasped.
If a new job cannot be executed until another job is completed, a new job can be executed by grasping the amount of processing performed by another means for executing another job after the new job is set. It is possible to appropriately determine whether or not to accept a simple job.

  Further, according to the multifunction device 1, if the execution means (first execution means) executing another job and the execution means (second execution means) for executing a new job are not common, the "execution means New jobs are accepted regardless of the amount of processing until a new job can be executed, so another job and a new job can be executed in parallel, and the job can be executed efficiently. it can.

Furthermore, according to the multifunction device 1, the input means of the first execution means is common to either the input means or the output means of the second execution means, and the output means of the first execution means is the input of the second execution means. When it is determined that neither the means nor the output means is common, the processing amount to be processed before the first execution unit finishes inputting the image is grasped as the processing amount.
For example, another direct print job input unit (USB memory) is in common with a new scan to USB job output unit (USB memory), and another direct print job output unit (printing unit 41) is a new scan to USB job. It is not common to any of the job input means (reading unit 25) and output means (USB memory). In this case, a new scan-to-USB job can be executed when input of an image by another direct print job is completed.
Therefore, in this case, the execution means (first execution means) for executing another direct print job by grasping the processing amount of another direct print job to be processed before the image reading from the USB memory is completed. The execution of a new scan-to-USB job can be started at an earlier timing than in the case of grasping the processing amount to be processed until the end of image output.

Further, according to the multifunction device 1, when the output means of the first execution means and the input means of the second execution means are not in common, the second execution means inputs the image by the first execution means. Run in parallel with image output.
For example, when another job is a copy job and a new job is also a copy job, the output unit (printing unit 41) of the first execution unit that executes another copy job and the first copy unit that executes the new copy job. Since the second execution means is not common to the input means (reading section 25) of the second execution means, the second execution means reads the image by the reading section 25 and reads the image by the output means (printing section 41) of the first execution means. Run in parallel with printing. Thereby, the job can be executed efficiently.

  Furthermore, according to the multifunction machine 1, a new job is accepted regardless of the processing amount for a user who is given authentication information. When authentication information is input after a new job can be executed, the new job is executed. If a user who is given authentication information leaves the multifunction device 1 after setting a new job, the new job may be executed while the user is away and the processing result may be viewed by other users. There is. According to the multifunction device 1, after the new job can be executed, when the authentication information is input, the new job is executed. Therefore, the user who is given the authentication information can execute the new job by the execution unit. By returning to the multifunction device 1 and entering the authentication information in anticipation of the time when execution is possible, the possibility that the processing result is viewed by other users can be reduced.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  (1) In the above embodiment, the case where it is determined that a new job is not accepted when the processing amount is larger than the predetermined amount has been described as an example. It may be determined that a job is accepted. In this case, the user can know that the amount of processing is large by accepting the job, and it is understood that the new job set by himself / herself is not executed immediately.

  (2) In the above embodiment, the time until a new job can be executed is estimated from the processing amount, and the case is determined based on the estimated time (estimated time) whether or not to accept a new job. Although described, it may be determined directly from the grasped processing amount. Since there is a correlation between the amount of processing and the estimated time, if the amount of processing is large, it is determined that it will take a long time to complete processing by another job, and it will not accept a new job without estimating the time. May be.

(3) In the above embodiment, the case where the predetermined time (an example of the predetermined amount) to be compared with the estimated time is constant has been described as an example, but it is compared with a predetermined time that differs depending on the time required to execute a new job. You may do it.
For example, when a new job is a job that ends in a short time, a user who sets a new job may feel long even for a time of, for example, 50 seconds. Conversely, when a new job takes a long time, a user who sets a new job may not feel the time of 50 seconds so long.
Therefore, the impression that the user feels about the relationship between the time required for executing a new job and the waiting time is examined, and based on the result, a predetermined time is set according to the time required for executing the new job. Also good.

  (4) In the above embodiment, the job illustrated in FIG. 2 has been described as an example of a job for processing an image. However, the job for processing an image is not limited to these, and other jobs may be performed depending on the functions of the image processing apparatus. A job may be set.

  (5) In the above-described embodiment, a multifunction peripheral has been described as an example of the image processing apparatus. However, the image processing apparatus may not be configured as a single device, for example, a PC and an image scanner or printer connected to the PC. You may comprise by.

  (6) In the above embodiment, “the processing amount processed until the execution means can execute a new job” is set as “the processing amount processed before the execution of another job” and “the other job's execution”. The case where the input means grasps the processing amount to be processed before the execution of the other job is explained as an example, but the remaining processing amount of another job and the processing amount of another job do not change much Alternatively, the processing amount of another entire job may be grasped.
