Description

  The present invention relates to an image forming system and an image forming apparatus that perform post-processing jobs.

  2. Description of the Related Art Conventionally, an image forming apparatus connects a post-processing apparatus to a main body of the image forming apparatus, and performs a series of processes including print processing, post-processing such as stapling, punching and folding. The type of post-processing to be applied to the sheet on which the image is formed by the image forming apparatus can generally be set from the operation panel provided on the main body of the image forming apparatus. On the other hand, there is also a use case in which print processing and post-processing are not performed as a series of processing, but print processing and post-processing are performed independently. A specific use case is to post-process only the documents distributed at the meeting. Although there is a post-processing machine physically independent of the image forming apparatus in order to perform only post-processing, it has also been proposed that only post-processing is performed by a post-processing machine connected to the image forming apparatus. Patent Document 1 discloses an image forming system in which only post-processing can be performed as one post-processing job by a post-processing apparatus connected to an image forming apparatus, and a post-processing job can be reserved. By making it possible to reserve a post-processing job, it is possible to improve the operation rate of the image forming system.

  However, the user may leave the imaging system for another task after scheduling a post-processing job on the imaging system. Thereafter, another user removes the printed sheet on which the post-processing job should be performed from the image forming system without setting that the post-processing job is reserved, and sets another printed sheet in the image forming system. There is. In that case, there is a problem that post-processing is performed on unintended printed sheets. Also, the other user may notice that the post-processing job is reserved after removing the printed sheet from the imaging system and may return the printed sheet to the imaging system in the wrong orientation. In that case, there is a problem that post-processing is performed on the wrong portion of the printed sheet. Since the pre-printed sheet on which the post-processing job should be performed may be only one original, the effect of erroneously performing the post-processing is large.

  Therefore, the present invention provides an image forming system that displays a message on the display unit when the sheet on which the post-processing job is to be performed is removed.

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

First Embodiment
(Printing system)
An image forming system (hereinafter, referred to as a printing system) 100 according to a first embodiment will be described. FIG. 1 is a diagram showing a printing system 100. As shown in FIG. The printing system 100 according to the first embodiment includes an image forming apparatus 101, an inserter 102, and a post-processing apparatus. The image forming apparatus 101 is connectable to the inserter 102 and the post-processing apparatus. The post-processing machine of the first embodiment includes a punching machine 103, a folding machine 104 and a stapler (stitching machine) 105.

Further, the image forming apparatus 101 receives image data from an external device, and forms an image on a sheet based on the received image data.

  The inserter 102 has a stacking unit (hereinafter, referred to as a feeding unit) 107 on which a document or a sheet on which an image is formed (a printed sheet) is stacked. The inserter 102 feeds a sheet to the punching machine 103, the folding machine 104, or the stapling machine 105 at the subsequent stage without passing through the conveyance path of the image forming apparatus 101. The inserter 102 according to the first embodiment has one feeding unit 107, but may have a plurality of feeding units. The feeding unit 107 may have another configuration as long as it can feed a sheet to the post-processing apparatus in the subsequent stage without passing through the conveyance path of the image forming apparatus 101. The inserter 102 includes a sheet sensor (sheet detection unit) 106 that detects the presence or absence of a sheet placed on the feeding unit 107.

  The punching machine 103 punches a sheet in accordance with an instruction from the image forming apparatus 101. The type of hole may be predetermined to two holes or multiple holes. The drilling machine 103 may be capable of selecting the number of holes in accordance with an instruction from the image forming apparatus 101. The folding machine 104 folds the sheet in accordance with an instruction from the image forming apparatus 101. The folding machine 104 can perform two-fold folding of the sheet in half, three-fold inward folding in two places of the sheet, and outer-three-fold folding in Z shape when the sheet is viewed from the side. The folded sheet is discharged to the discharge unit 108 at the lower stage of the folding machine 104. The stapler 105 staples the sheet with a needle in accordance with an instruction from the image forming apparatus 101. The stapler 105 can bind one place at four corners of the sheet, or can bind one side of the sheet at two places.

(Image forming device)
Next, the image forming apparatus 101 will be described with reference to FIG. FIG. 2 is a block diagram of the image forming apparatus 101. The image forming apparatus 101 includes a controller unit (control device) 201, a display unit 202, an operation unit 203, a printer unit 204, and a scanner unit 205. The display unit 202 includes an LED and a liquid crystal display, and displays the user's operation content and the internal state of the device. The operation unit 203 receives an operation from the user. Furthermore, the operation unit 203 may be realized as a touch display together with the display unit 202, in addition to having a plurality of operation buttons. The printer unit 204 receives a print instruction from the controller unit 201, and forms an image on a sheet in accordance with image data transmitted from the controller unit 201.

  The scanner unit 205 receives a reading instruction from the controller unit 201, reads an image of a document, and transmits image data of the document to the controller unit 201. The controller unit 201 includes a central processing unit (hereinafter referred to as a CPU) 206, a ROM 207, a RAM 208, a hard disk drive (hereinafter referred to as an HDD) 209, and an EEPROM 210. The ROM 207 is a read only memory that stores a boot program necessary for system startup. The RAM 208 is a volatile memory and is a work memory required to execute the control program. The HDD 209 is a storage medium such as a magnetic disk, and stores control programs and image data. An EEPROM 210 as a storage unit is a non-volatile memory that stores setting values required when executing a control program. The controller unit 201 is connected to the inserter 102, the punching machine 103, the folding machine 104, and the stapling machine 105 via a control communication I / F (not shown). The controller unit 201 can make settings for the operation of these post-processing machines, and can acquire the status of these post-processing machines. The state of the inserter 102 includes the state of the presence or absence of a sheet in the feed unit 107 of the inserter 102. A CPU 206 as a computer controls the operations of the inserter 102, the punch 103, the folder 104, the stapler 105, the printer unit 204, and the scanner unit 205 in accordance with a control program stored in the HDD 209.

(Use case of the first embodiment)
Next, an example of the use case (interaction between the user and the printing system 100) according to the first embodiment will be described with reference to FIG. FIG. 3 is a diagram showing the operation of the users A and B and the operation of the image forming apparatus 101 in the first embodiment. Here, a job for performing print processing with only image formation processing (hereinafter, referred to as print processing) or post-processing is referred to as an image formation job. The image forming job forms an image on a sheet based on a copy job for forming an image on a sheet based on image data of a document read by the scanner unit 205 and image data input to the image forming apparatus 101 from an external device. And print jobs. A job that performs only post processing is called a post processing job. Post processing includes, for example, insertion of sheets by the inserter 102, punching of sheets by the punching machine 103, folding of sheets by the folding machine 104, binding of a bundle of sheets by the stapling machine 105, and binding of sheets by a bookbinding machine (not shown). Say. A job that is not executed immediately after input because the previously input job is being executed but does not wait until the previous job ends is called a reserved job. In FIG. 3, while the copy job input by user A is being executed, the post-processing job is input by user A as a reserved job, and thereafter, the sheet on which the post-processing job of user A should be performed by another user B is supplied. An example when removed from the sending unit is shown.

  First, the user A places an original on the scanner unit 205 and inputs a copy job. When the image forming apparatus 101 receives a copy job, the scanner unit 205 reads an image of a document to generate image data, and the printer unit 204 forms an image on a sheet according to the generated image data. After reading the image of the document, the image forming apparatus 101 can receive the next job even while the image formation by the printer unit 204 is being performed. In the example illustrated in FIG. 3, the user A places a sheet on the feeding unit 107 of the inserter 102 following a copy job, and inputs a post-processing job to the image forming apparatus 101. Since the copy job is being executed, the image forming apparatus 101 accepts the input post-processing job as a reservation job. The transport path for transporting the sheet to be post-processed is overlapped with the transport path for transporting the sheet on which the image is formed by the previously input copy job. Therefore, the printing system 100 can not execute the post-processing job unless the copy job ends. Therefore, even if the image forming apparatus 101 receives the post-processing job, it can not start the post-processing job until the copy job is completed. Therefore, when the post-processing job is input during execution of the copy job, the image forming apparatus 101 receives the post-processing job as a reserved job. The reservation job is not started when it is accepted, but is started when all the previously accepted jobs are completed. Therefore, the user A often leaves the image forming apparatus 101 when the post-processing job is accepted as a reservation job.

  After the user A has left the image forming apparatus 101, a user B different from the user A comes to the image forming apparatus 101 to use the inserter 102. The user B is not aware that the post-processing job of the user A is reserved, and the sheet of the user A placed on the feeding unit 107 of the inserter 102 is left to use the inserter 102. Get rid of it. According to the first embodiment, the sheet removed from the feeding unit 107 is correctly displayed on the display unit 202 of the image forming apparatus 101 to the original feeding unit 107 at the timing when the user B removes the sheet of the user A. A message is displayed prompting you to return in a state. The user B who sees the message on the display unit 202 notices that the post-processing job by another user is reserved, and can return the sheet removed from the feeding unit 107 to the correct state. Thus, after the copy job of the user A is completed, the post-processing job of the user A is correctly executed.

(Job list generation operation)
Next, with reference to FIG. 4, a job list generating operation for generating a job list for managing an input job will be described. The job input to the image forming apparatus 101 by the user is added to the job list. The CPU 206 functions as an image forming job for performing an image forming process with post-processing and a post-processing job for performing only the post-processing without performing the image forming process. The CPU 206 functions as a job list generation unit that generates a job list for managing received jobs. FIG. 4 is a flowchart showing the job list generating operation executed by the CPU 206. The CPU 206 of the image forming apparatus 101 executes a job list generation operation according to the control program stored in the HDD 209. First, in step S <b> 401, the CPU 206 displays the main screen 501 on the display unit 202. The user selects a function to be performed on the main screen 501. FIG. 5 is a view showing a screen displayed on the display unit 202. As shown in FIG. FIG. 5A is a view showing an example of the main screen 501. The main screen 501 has a copy icon 502 and a post-processing icon 503. The user touches the copy icon 502 when inputting a copy job. When the user inputs a post-processing job, the user touches the post-processing icon 503. The user can select whether the input job is a copy job or a post-processing job on the main screen 501. Although the main screen 501 shown in FIG. 5A shows the copy icon 502 and the post-processing icon 503, the main screen 501 may have icons other than these. In step S402, the CPU 206 determines which icon has been touched. The CPU 206 functions as a job determination unit (first determination unit) that determines whether the job input by the user is a copy job or a post-processing job. If the copy icon is touched, the CPU 206 advances the process to step S403 to set a copy job. If the post-processing icon is touched, the CPU 206 advances the process to step S408 in order to set a post-processing job.

  If the copy icon is touched, the CPU 206 displays a copy setting screen 504 for setting a copy job in S403. FIG. 5B is a diagram showing an example of the copy setting screen 504. The copy setting screen 504 includes a number of copies setting unit 505, a feeding unit setting unit 506, and a post-processing setting unit 507. The user uses the number of copies setting unit 505 to set the number of sheets (number of copies) on which an image of one document is formed (copied). The user uses the feeding unit setting unit 506 to set a feeding unit for feeding a sheet on which an image is to be formed. The user uses the post-processing setting unit 507 to set the post-processing to be performed on the sheet on which the image is formed. The copy setting screen 504 may have a setting unit related to the copy job in addition to these. In step S404, the CPU 206 receives the setting of the copy job.

  In step S405, the CPU 206 determines whether a start instruction has been received from the operation unit 203. If the start instruction has not been received from the operation unit 203 (NO in S405), the CPU 206 returns the process to S404 and receives the setting of the copy job. When the start instruction is received from the operation unit 203 (YES in S405), the CPU 206 causes the scanner unit 205 to start the document reading process in S406. When there are a plurality of originals, all originals are read. Further, image data read from a document is temporarily stored in the HDD 209. In step S407, the CPU 206 adds a copy job to the job list for managing the input job. The CPU 206 saves the job list in the EEPROM 210, and ends the job list generation operation.

  An example of the job list will be described with reference to FIG. FIG. 6 is a diagram showing the job list 601. As shown in FIG. The job list 601 has items of an execution order 602, a job type 603, an execution status 604, a sheet size 605, an output sheet number 606, a feeding unit 607, and a post-processing 608. The input job is added next to the final job when the job is input. A value obtained by adding 1 to the final job execution order 602 is set as the input job execution order 602. In the job type 603, a copy job, a post-processing job, or a print job is set in accordance with the type of the input job. In the execution status 604, "being executed" is set for the job being executed at that time, and "waiting for execution" is set for the job (reserved job) waiting at that time. When a job is input, “waiting for execution” is once set in the execution status 604. Thereafter, when the execution of the job is actually started, the execution status 604 of the job is updated to “in execution”.

  The sheet size 605 displays the size of the sheet to be output. The number of output sheets 606 is displayed. For example, in the case of a copy job, when the number of originals is five and the number of copies is 2, the number of output sheets is ten. The feeding unit 607 displays a feeding unit for feeding a sheet to be output. For example, in the case of a copy job, the feeding unit 607 displays the feeding unit (setting feeding unit) set by the feeding unit setting unit 506 of the copy setting screen 504. The post-processing 608 displays the post-processing to be executed on a sheet output as a copy job or a print job or a sheet placed on the feeding unit 107 of the inserter 102. For example, in the case of a copy job, the post-processing set by the post-processing setting unit 507 of the copy setting screen 504 is displayed in the post-processing 608. The job list 601 is not limited to the items shown in FIG. 6, and may further include items necessary for managing a job.

  Next, a case where the post-processing icon 503 on the main screen 501 is touched by the user will be described. When the post-processing icon 503 is touched, the CPU 206 displays a post-processing setting screen 508 for setting a post-processing job in S408. FIG. 5C shows an example of the post-processing setting screen 508. The post-processing setting screen 508 includes a number setting unit 509, a feeding unit setting unit 510, a sheet size setting unit 511, and a post-processing setting unit 512. The user sets the number of sheets of paper on which post-processing is to be performed by using the number-of-sheets setting unit 509. The user uses the sheet feeding unit setting unit 510 to set a sheet feeding unit for feeding a sheet to be subjected to post-processing. The user uses the sheet size setting unit 511 to set the size of the sheet on which the post-processing should be performed. The user uses the post-processing setting unit 512 to set the post-processing to be performed on the sheet. The post-processing setting screen 508 may have a setting unit related to the post-processing job in addition to these. In step S409, the CPU 206 receives the setting of the post-processing job.

  In step S410, the CPU 206 determines whether a start instruction has been received from the operation unit 203. If the start instruction has not been received from the operation unit 203 (NO in S410), the CPU 206 returns the process to S409 and receives the setting of the post-processing job. If the start instruction has been received from the operation unit 203 (YES in S410), the CPU 206 adds a post-processing job to the job list 601 in S411. The post-processing job is added next to the final job. A value obtained by adding 1 to the final job execution order 602 is set as the input post-processing job execution order 602. A post-processing job is set as the job type 603. In the execution status 604, execution waiting is set once, as in the case of the copy job. In the sheet size 605, the number of output sheets 606, the feeding unit 607, and the post-processing 608, set values set on the post-processing setting screen 508 are set. The CPU 206 saves the job list in the EEPROM 210, and ends the job list generation operation.

(Job execution operation)
Next, a job execution operation for executing the input copy job and post-processing job will be described with reference to FIG. FIG. 7 is a flowchart showing the job execution operation. The CPU 206 executes the job execution operation in accordance with the control program stored in the HDD 209. First, in step S <b> 701, the CPU 206 acquires a job list 601. Next, in step S 702, the CPU 206 determines whether there is a job to be executed in the job list 601. If there is no job to be executed (NO in S702), the CPU 206 ends the job execution operation. If there is a job to be executed (YES in step S702), the CPU 206 acquires top job information from the job list 601 in step S703. Specifically, the CPU 206 acquires job information whose execution order 602 of the job list 601 is “1”. When the job type 603 of the job information is a copy job, the CPU 206 reads the image data read in S406 from the HDD 209. Next, in step S704, the CPU 206 updates the execution status 604 of the top copy job of the job list 601 to "executing".

  The CPU 206 performs processing according to the job type in step S705 and subsequent steps. In step S 705, the CPU 206 determines the job type based on the job type 603 in the job list 601. If the job type is a copy job, in step S706, the CPU 206 transmits the image data acquired in step S703 to the printer unit 204, and causes the printer unit 204 to execute print processing. When a plurality of copies are set by the number of copies setting unit 505, the CPU 206 transmits image data to the printer unit 204 according to the set number of copies. In step S 707, the CPU 206 transmits information on post-processing settings set along with the copy job to the corresponding post-processing device. The post-processing apparatus performs post-processing on the printed sheet in accordance with the received information on the setting of post-processing.

  On the other hand, if the job type is the post-processing job in step S705, the CPU 206 performs post-processing on the sheet fed from the feeding unit in step S708, as in step S707. When the job ends, the CPU 206 deletes the corresponding job from the job list 601 in S709. This process includes a process of advancing the execution order 602 of jobs whose execution order 602 of the job list 601 is “2” or later one by one. Thereafter, the CPU 206 returns the process to step S701. In the job execution operation, the copy job or the post-processing job is executed according to the job information set in the job list 601.

(Paper presence / absence detection operation)
Next, with reference to FIGS. 8 and 9, the sheet presence / absence detection operation when the sheet on which the reserved post-processing job is to be performed is removed from the printing system 100 will be described. The presence or absence of a sheet is detected by each of the plurality of feeding units of the post-processing apparatus (102 to 105), and the CPU 206 monitors the detection result. The sheet presence / absence detection operation is performed when the sheet presence / absence state in each feeding unit is changed. FIG. 8 is a flowchart showing the sheet presence / absence detection operation executed by the CPU 206 in the first embodiment. The CPU 206 executes the sheet presence / absence detection operation in accordance with the control program stored in the HDD 209.

  When the sheet placed on any of the plurality of sheet feeding units of the post-processing apparatus is removed by the user, the detection result of the sheet sensor changes from the presence state to the non-state. In step S801, the CPU 206 determines whether the detection result of the sheet sensor provided in the feeding unit has changed from the presence state to the non-state. The CPU 206 functions as a sheet detection unit that detects whether there is a sheet in each of the plurality of feeding units. If the detection result of the sheet sensor has not changed from the presence state to the non-state (NO in S801), the CPU 206 ends the sheet presence / absence detection operation. In this case, since the detection result of the sheet sensor changes from the non-state to the presence state by the sheet being placed in the feeding unit, the CPU 206 ends the sheet presence / absence detection operation and monitors the detection result of the sheet sensor. continue. On the other hand, when the detection result of the sheet sensor changes from the presence state to the non-state (YES in S801), the CPU 206 advances the process to S802. In step S802, the CPU 206 determines whether there is a post-processing job in the job list 601. The CPU 206 serves as a post-processing job presence determination unit (second determination unit) that determines whether the post-processing job is included in the job list 601 when the detection result of the sheet sensor changes from the presence state to the non-state. Function. If there is no post-processing job (NO in S802), the CPU 206 ends the sheet presence / absence detection operation. If there is a post-processing job (YES in step S802), the CPU 206 advances the process to step S803.

  In step S 803, the CPU 206 determines whether the feeding unit (setting feeding unit) set in the post-processing job is the feeding unit (detection feeding unit) in which the detection result of the sheet sensor changes from the presence state to the non-state. Decide whether or not. The CPU 206 is a feeding unit that feeds sheets for which the feeding unit whose detection result changes from the presence state to the non-state is a post-processing job when it is determined that the post-processing job is included in the job list 601. It functions as a feeding section determination unit (third determination unit) that determines whether there is any. If the set feeding unit is not the detection feed unit (NO in S803), the CPU 206 ends the sheet presence / absence detection operation. If the setting feeding unit is the detection feeding unit (YES in S803), the sheet on which the reserved post-processing job is to be performed has been removed from the feeding unit, and thus the CPU 206 detects and feeds the sheet in S804. The display unit 202 displays a message prompting the user to return to the unit in the correct state. The CPU 206 functions as a display unit that displays a message on the display unit 202 when the detection feeding unit is the set feeding unit. An example of the message display screen 901 is shown in FIG. FIG. 9 is a view showing a message display screen 901 displayed on the display unit 202. As shown in FIG. The message display screen 901 displays information that the post-processing job is reserved and information for returning the sheet to the detection / feed unit (original feed unit) in a correct state. After the message is displayed, in step S805, the CPU 206 determines whether the sheet has been returned to the detection feeding unit (original feeding unit). Whether or not the sheet has been returned to the detection feed unit is determined based on the detection result of the sheet sensor provided in the detection feed unit. If the sheet has not been returned to the detection / feed unit (NO in S805), the CPU 206 waits until the sheet is returned to the detection / feed unit. When the sheet is returned to the detection feed unit, the detection result of the sheet sensor changes from the non-state to the state. If the sheet is returned to the detection / feeding unit (YES in S805), the CPU 206 erases the message from the display unit 202 in S806. The CPU 206 ends the sheet presence / absence detection operation.

  In the first embodiment, a message is displayed on the display unit 202 at the timing when the sheet on which the reserved post-processing job is to be performed is removed from the feeding unit. However, the timing of displaying the message is not limited to this. The sheet on which the reserved post-processing job is to be performed may be removed from the feeding unit, and then a message may be displayed on the display unit when the sheet is returned to the feeding unit. Alternatively, the message may be displayed immediately before executing the post-processing job.

  According to the first embodiment, when the sheet to be subjected to the post-processing job is removed from the feeding unit while waiting for the reserved post-processing job, the user is requested to return the sheet to the feeding unit in the correct state. A prompting message may be displayed to determine whether the sheet has been returned to the feeding unit. The user can return the sheet to the feeding section in a correct state according to the message. Therefore, it is possible to prevent post-processing on the wrong sheet or post-processing on the wrong part of the sheet.

  According to the first embodiment, when the sheet on which the post-processing job is to be performed is removed, a message can be displayed on the display unit.

Second Embodiment
The second embodiment will be described below with reference to FIGS. 10 and 11. In the second embodiment, the same structure as that of the first embodiment is denoted by the same reference numeral and the description is omitted. The printing system 100, the image forming apparatus 101, the job list generation operation, and the job execution operation of the second embodiment are the same as those of the first embodiment, and thus the description thereof is omitted. The use case and the sheet presence / absence detection operation of the second embodiment are different from those of the first embodiment, and therefore, the differences will be mainly described below.

(Use case of the second embodiment)
An example of the use case (interaction between the user and the printing system 100) according to the second embodiment will be described with reference to FIG. FIG. 10 is a diagram showing the operation of the users A and B and the operation of the image forming apparatus 101 in the second embodiment. In FIG. 10, similarly to FIG. 3, during the execution of the copy job input by the user A, the post-processing job is input by the user A as a reservation job, and then another user B performs the post-processing job of the user A An example is shown when the paper to be performed is removed from the feed station.

  The action from the user A inputting a copy job to the user B removing the sheet of the user A placed on the feeding unit 107 of the inserter 102 is the same as in FIG. 3 in the first embodiment. , I omit the explanation. When the sheet is removed from the feeding unit 107 of the inserter 102, the image forming apparatus 101 cancels the post-processing job reserved by the user A. This can prevent post-processing on the wrong sheet.

(Paper presence / absence detection operation)
Next, with reference to FIG. 11, the sheet presence / absence detection operation when the sheet on which the reserved post-processing job is to be performed is removed from the printing system 100 will be described. The presence or absence of a sheet is detected by each of the plurality of feeding units of the post-processing apparatus (102 to 105), and the CPU 206 monitors the detection result. The sheet presence / absence detection operation is performed when the sheet presence / absence state in each feeding unit is changed. FIG. 11 is a flowchart showing the sheet presence / absence detection operation executed by the CPU 206 in the second embodiment. The CPU 206 executes the sheet presence / absence detection operation in accordance with the control program stored in the HDD 209.

  The processing of S1101 to S1103 shown in FIG. 11 is the same as the processing of S801 to S803 shown in FIG. If the setting feed unit is the detection feed unit (YES in step S1103), the sheet on which the reserved post-processing job is to be performed has been removed from the feed unit, the CPU 206 removes the sheet in step S1104. It is determined whether the state has reached a predetermined time. Whether or not the state in which the sheet has been removed has elapsed for a predetermined time is determined based on whether or not the absence state of the detection result of the sheet sensor 106 has not changed and the predetermined time has elapsed. The predetermined time may be a predetermined time or a time set by the user. Also, the predetermined time may be 0 seconds. If the predetermined time has not elapsed (NO in step S1104), in step S1105, the CPU 206 determines whether the sheet has been returned to the detection feeding unit (original feeding unit). If the sheet is returned to the detection / feeding unit (YES in S1105), the CPU 206 ends the sheet presence / absence detection operation. If the sheet is not returned to the detection / feeding unit (NO in S1105), the CPU 206 returns the process to S1104. If the predetermined time has elapsed (YES in S1104), the CPU 206 cancels the corresponding post-processing job in S1106. At this time, the CPU 206 may notify the user A who has input the post-processing job that the post-processing job has been canceled. The CPU 206 deletes the post-processing job from the job list 601. This process also includes the process of advancing the job execution order 602 of “2” and subsequent jobs one by one in the execution order 602 of the job list 601. The CPU 206 functions as a deletion unit that deletes the corresponding post-processing job from the job list 601 when the detection feeding unit is the setting feeding unit.

  According to the second embodiment, when the sheet to be subjected to the post-processing job is removed from the feeding unit while waiting for the reserved post-processing job, the reserved post-processing job can be canceled. Therefore, it is possible to prevent post-processing on the wrong sheet or post-processing on the wrong part of the sheet.

  According to the second embodiment, when the sheet on which the post-processing job is to be performed is removed, the corresponding post-processing job can be deleted from the job list.
