Description

  The present invention relates to an image forming apparatus, and more particularly, to an image forming system having a sheet processing apparatus that performs glue binding processing, a control method, a storage medium, a computer program, an image forming apparatus, and the like.

  In recent years, bookbinding printing (booklet printing) using an imposition function based on digital image processing has become possible in digital multi-function peripherals, and a sheet processing apparatus for saddle stitching booklet printing has been proposed.

  A process that can be realized by such a sheet processing apparatus with a saddle stitch bookbinding function is a simple bookbinding process. In the future, in addition to simple bookbinding processing such as booklet printing, there is a possibility that full-scale bookbinding processing such as original bookbinding, for example, gluing bookbinding processing that applies glue processing to printed matter, may be required. It is done. In order to propose such a gluing bookbinding function, a configuration like a gluing bookbinding apparatus disclosed in Japanese Patent Application Laid-Open No. 2002-293060 (Patent Document 1) is being studied.

  There is a possibility that such a gluing bookbinding apparatus has a size equivalent to or larger than that of a digital multifunction peripheral. Such a large size glue binding machine can be costly and occupy a large area. Therefore, it is expected that the introduction will be difficult except for users who have a dedicated space such as a copy machine room.

Therefore, it is being studied to reduce the size of the glue binding apparatus. By reducing the size, the cost is reduced and the occupied area is also reduced. Thus, by reducing the size of the gluing bookbinding device, it is expected that even a user who cannot secure a dedicated space can introduce a device equipped with a gluing bookbinding machine.
JP 2002-293060 A

  However, when considering reducing the size of the gluing bookbinding machine, the following restrictions are expected to occur.

(1) Binding of large size (A3 size, B4 size) cannot be performed.

(2) Similarly, the number of sheets that can be glued at once is limited to a limited number.

(3) Depending on the type of paper, the number of sheets that can be glued at a time also changes. For example, in the case of thick paper, the number of sheets that can be glued decreases as the paper thickness increases.

  Looking at the market, the need for small size (A4, LTR size or smaller) bookbinding is overwhelmingly higher than that for large size (A3 size, B4 size) bookbinding, and large size (A3 size, B4 size). The need for binding is low. On the other hand, for example, an ordinary digital multi-function peripheral also supports large size printing.

  Therefore, for example, assuming that it becomes possible to realize glue binding in an image forming apparatus or image forming system such as a small-sized digital multifunction peripheral, the user can also perform large-size binding. There seems to be a possibility of illusion.

  In addition, for example, due to such misunderstanding of the user, printing on large size paper is designated, and eventually, even if printing is possible, an error occurs during bookbinding due to the restriction (1) above. Such a problem may occur. Thus, problems such as wasting user's effort and resources may occur.

  Further, for example, with respect to the limit number of sheets that can be processed as described in (2) and (3) above, a user who does not know the limit number of sheets tries to print and book a number of sheets exceeding the limit number, and performs bookbinding processing. It is also anticipated that a failure will occur and the user's effort and resources will be wasted frequently.

  In addition, for example, especially when trying to perform a bookbinding process using cardboard or the like, as shown in (3) above, the limit number of sheets is different from that when using plain paper. It is difficult to grasp, and there is a concern that failures during bookbinding occur frequently.

  Thus, for users who do not know the device specifications in detail, bookbinding processing errors frequently occur and problems such as inconvenience are assumed.

  Thus, for example, in order to be able to provide a user with an image forming apparatus such as a digital multi-function peripheral, or a product that enables gluing processing in an image forming system including the same, to a user, There are issues to be addressed.

  In addition to the above points, there seems to be a problem to be examined. For example, it is desirable to be able to cope with such needs in consideration of the possibility that the user desires various bookbinding processes. In addition, for example, it is desirable to be able to cope with such needs in consideration of the possibility that the user desires a wide variety of output forms when performing gluing bookbinding printing.

  In this way, for example, it is desirable to be able to provide an apparatus and a system that can flexibly meet various needs from various users involved in the gluing bookbinding process, can be used easily, and can improve user merits. .

  As described above, for example, there is still room for examination in order to put into practical use an image forming apparatus such as a digital multi-function peripheral or a product that enables gluing processing in an image forming system including the image forming apparatus. It can be said that.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming system, a control method, a storage medium, a program, and an image forming apparatus that can solve the above-described problems.

  In addition, the present invention has an illusion (misunderstanding) as if a user can perform large-size bookbinding, and designates printing and bookbinding on a large-size paper, A user who does not know the maximum number of sheets that can be processed and the minimum number of sheets that can be processed is caused by limitations due to downsizing, such as a failure in bookbinding processing due to printing and bookbinding of sheets exceeding the maximum number. An object of the present invention is to provide an image forming apparatus and an image forming system that are small and inexpensive, capable of performing a gluing bookbinding process with reduced occurrence of failures.

  In addition, the present invention can suppress the occurrence of troubles during glue binding due to, for example, the reduction in size of the apparatus that performs the glue binding process, and the restrictions generated due to cost, installation area, and downsizing. It is an object of the present invention to provide an image forming system, a control method, a storage medium, a program, and an image forming apparatus that can solve problems such as inconvenience associated with use.

  In addition, the present invention enables, for example, a case where the case binding process cannot be executed to dynamically change the selection to the top book binding process at that time, thereby making it possible to effectively use the once read image as it is without being wasted. An object of the present invention is to provide an image forming system, a control method, a storage medium, a program, and an image forming apparatus capable of performing bookbinding processing.

  The present invention also provides an image forming system and an image forming system that can cope with such needs in consideration of the possibility that the user desires a wide variety of print output forms, for example, when performing gluing bookbinding printing. An object is to provide a control method, a storage medium, a program, and an image forming apparatus.

Is invalidated, and the display on the liquid crystal display unit 4-250 is returned to the screen of FIG.

  A key 4-286 is a key for enabling detailed setting by the user. When the key 4-286 is pressed by the user, the CPU circuit unit 122 responds to the key 4-286 and the liquid crystal display unit 4- 250 displays a double-sided printing detailed setting screen shown in FIG. Hereinafter, detailed settings for duplex printing will be described with reference to FIG.

  In FIG. 5D, a key 4-290 is a setting key for printing a double-sided printed material in a left-right direction, and a key 4-291 is a setting key for printing a double-sided printed material in a vertical direction. When the type of double-sided printing is selected using the key 4-291 or the key 4-292 and the close key 4-292 is pressed, the CPU circuit unit 122 closes this screen, and the display on the liquid crystal display unit 4-250 is displayed as shown in FIG. Return to the screen of (c).

  As described above, duplex printing can be set by the duplex printing setting screen in FIG. 5C and the duplex printing detailed setting screen in FIG.

  A key 4-256 on the display screen in FIG. 4 enables the user to input an instruction to display a setting screen for the user to instruct the sheet processing to be executed by the sheet processing apparatus 230 on the display unit of the operation unit 123. This is a sorta key.

  When the user presses the key 4-256, in response to this, the CPU circuit unit 122 displays the display on the liquid crystal display unit 4-250 of the operation unit 123, for example, a sheet processing setting screen 1900 shown in FIG. To migrate. Then, by displaying the setting screen 1900 on the display unit 4-250, sheet processing candidates that can be executed by the sheet processing apparatus 230 (stapling processing, punching processing, cutting processing, case binding processing, top binding processing, shift) The CPU circuit unit 122 controls to present to the user selection candidates related to sheet processing such as paper discharge processing.

  The CPU circuit unit 122 allows a user to accept a desired sheet processing execution instruction via a sheet processing setting screen as shown in FIG. Then, the sheet processing device 230 is executed by the CPU circuit unit 122 so that the sheet processing corresponding to the instruction by the user via the sheet processing setting screen is executed for the sheet of the job to be processed from the printer unit 2. To control.

  A key 4-260 is an application mode key. When the user presses the key 4-260, the CPU circuit unit 122 responds to this, and the display on the liquid crystal display unit 4-250 is displayed as shown in FIG. Control is performed to enable setting of various application modes.

  Hereinafter, the flow of the bookbinding setting procedure in the image forming apparatus according to the present embodiment will be described with reference to FIGS.

  6 and 7 are schematic diagrams illustrating an example of an operation screen that the CPU circuit unit 122 controls to be displayed on the liquid crystal display unit 4-250 of the operation unit 123 as an example of the user interface unit illustrated in FIG. It is.

  FIG. 6A shows an application mode screen that the CPU circuit unit 122 displays on the display unit 4-250 when the key 4-260 on the operation screen shown in FIG. 4 is pressed by the user.

  A key 801 on the screen of FIG. 6A is a display key (soft key) for setting a bookbinding mode (including glue binding and bookbinding processing modes such as case binding and top binding). When the user presses the key 801, the CPU circuit unit 122 displays the document size selection screen shown in FIG. 6B on the display unit 4-250.

  A key 811 on the screen of FIG. 6A is a continuous reading key. When the key 811 is pressed by the user, a large number of documents exceeding the amount that can be placed on the document feeder 101 at once are placed in multiple batches to form a series of documents. The CPU circuit unit 122 controls the operation unit 123, the reader unit 1, the image memory unit 120, the printer unit 2, and the like so that additional reading processing can be performed.

  FIG. 6B is an operation screen for designating the document size of a job to be processed in the bookbinding mode. A key group 802 on the screen of FIG. 6B is a manuscript size designation key for allowing the user to set a size that can be designated by the user as the manuscript size of the job to be processed in the bookbinding mode. For example, when the user presses the “A4” size on the screen of FIG. 6B and presses the “next” key, the CPU circuit unit 122 displays the liquid crystal display unit 4-250 in FIG. Display the operation screen shown in.

  FIG. 6C shows an operation screen for designating the type of bookbinding. When the user presses the glue binding key 803 on the setting screen in FIG. 6C, the user can specify glue binding processing (case binding processing, top glue binding processing, which will be described later). On the other hand, when the user presses the saddle stitch bookbinding key 804 on the setting screen of FIG. 6C, the user can designate saddle stitch bookbinding.

  The CPU circuit unit 122 responds to the setting of any one of the sheet processing of the gluing bookbinding process or the saddle stitch bookbinding process via the setting screen of FIG. The sheet processing setting is reflected as the processing condition of the job. As described above, a series of job processing conditions corresponding to an instruction received from the user is used for various controls (job processing control, display control, and the like) described later.

  The CPU circuit unit 122 sets various job processing conditions set based on an instruction from the user for a job to be processed via the user interface unit such as the operation unit 123 or the display unit 4-250. Based on this, the image forming system 1000 is controlled to execute various controls described later. For example, the following control will be performed to describe the glue binding process that can be executed by the image forming system 1000 of the present embodiment.

  The CPU circuit unit 122 of the image forming system according to the present embodiment determines whether or not the job processing conditions set by the user via the user interface as described above for the job to be processed satisfy a predetermined condition. Determine whether. Based on the determination result, whether or not the glue binding process is executed is controlled.

  For example, when the job to be processed is a job that satisfies a predetermined condition, control is performed to allow the sheet processing device 230 to execute the gluing process on the sheet of the job. On the other hand, when the job to be processed is a job that does not satisfy a predetermined condition, control is performed so that the sheet processing apparatus 230 prohibits execution of the gluing process on the sheet of the job.

  In the present embodiment, there are two types of gluing processes that the sheet processing apparatus 230 can execute on the sheet of the job to be processed fed from the printer unit 2. For example, the image forming system 1000 of this embodiment includes two types of sheet gluing processing modes, a case binding mode and a top gluing bookbinding mode, as an example (the two types of gluing processing will be described later).

  The CPU circuit unit 122 controls the sheet processing apparatus 230 to execute the gluing process mode selected by an instruction from the user among the two types of gluing process modes described above.

  As described above, the image forming system according to the present embodiment includes a plurality of types of gluing processing modes, and is configured to selectively execute these gluing processes for each job to be processed.

  Based on such a configuration, in this embodiment, the CPU circuit unit 122 or the like mainly determines whether or not a job to be processed for which processing conditions are set by a user satisfies a predetermined condition. Configured to check. Based on the determination result, the CPU circuit unit 122 or the like mainly determines whether or not to execute various predetermined processes related to (influencing) the sheet gluing process, including a plurality of types of gluing processes as described above. Have control.

  For example, it is assumed that the CPU circuit unit 122 determines that “the job to be processed is a job that satisfies the first predetermined condition”. In this case, the CPU circuit unit 122 permits selectively (alternatively) executing the case binding mode and the top binding mode. That is, control is performed so that the user can arbitrarily select the gluing processing mode desired by the user out of the case binding mode and the top glue binding mode.

  However, even when this control is performed, when these modes are selected by the user, control is performed so as to be an alternative. That is, the user is allowed to select only one desired gluing processing mode from these two gluing processing modes. In other words, the CPU circuit unit 122 prohibits simultaneous setting of both the case binding mode and the top binding mode for one job to be processed.

  Thereby, for example, a user who desires the case binding mode can provide a user's desired output result that has been subjected to a proper case binding process. On the other hand, it is possible to provide the user who desires the top-sheet binding mode with the user's desired output result that has been subjected to an appropriate top-sheet binding process.

  The image forming system 1000 according to the present embodiment can achieve such an effect that it can flexibly cope with various bookbinding processing needs from various users.

  Moreover, for example, this effect can be obtained by suppressing the occurrence of various problems as assumed in the prior art etc. in the image forming system 1000, in addition to the above effect. Can be obtained.

  Further, it is assumed that the CPU circuit unit 122 makes a determination different from the case described above. For example, it is assumed that the CPU circuit unit 122 gives a determination result corresponding to “the job to be processed is not a job that satisfies the first predetermined condition but is a job that satisfies the second predetermined condition”. In this case, the CPU circuit unit 122 permits only one of the two gluing processing modes of the case binding mode and the top glue binding mode to be selected and executed. The other gluing processing mode is controlled so that selection by the user itself is also prohibited (the other gluing processing mode is controlled so that it cannot be selected).

  For example, in this control, the user interface unit (here, the user interface unit corresponds to the operation unit 123 if a job from the reader unit 1 is processed. A job from an external device such as a host computer). If so, the CPU circuit unit 122 or the like mainly controls to allow the user to select the sheet binding mode via the operation unit of the external device. However, the CPU circuit unit 122 controls to prohibit the user from instructing the selection of the case binding mode via the user interface unit.

  As a result, for example, the occurrence of an erroneous operation by the user, such as the user accidentally setting the case binding mode, even though the job to be processed is a job that is not suitable for the case binding mode, Can be prevented. Further, for example, it is possible to prevent malfunctions and troubles from occurring in the image forming system due to the user performing such inappropriate settings. In addition, for example, it is possible to eliminate waste such as creating an output result different from the output result desired by the user.

  However, even when this control is executed (case binding mode is prohibited, only the case binding mode is permitted), for example, the CPU circuit unit 122 determines the case binding processing mode depending on an instruction from the user of the job. The operation unit 123, the printer unit 2, and the sheet processing device 230 are controlled so as to permit execution of the print operation of the job to be processed in a state where execution of is prohibited.

  In addition, depending on an instruction from the user of the job, the operation unit 123, the printer unit 2, and the sheet processing apparatus 230 are controlled so that the job processing condition can be changed from the case binding mode to the top binding mode.

  With such a configuration, for example, even if there are some restrictions, the present image forming system can be made as flexible as possible. In addition, for example, user convenience, device utilization efficiency, and the like can be improved.

  Further, it is assumed that the CPU circuit unit 122 further determines that the above case is not applicable. For example, it is assumed that the CPU circuit unit 122 makes a determination result corresponding to “the job to be processed is not a job that satisfies the first predetermined condition and is not a job that satisfies the second predetermined condition”. In this case, the CPU circuit unit 122 prohibits selecting and executing the case binding mode. In addition, it is also prohibited to select and execute the sheet binding mode. Thus, both of the two types of gluing processing modes are prohibited.

  As a result, for example, even if the job to be processed is not suitable for the case binding mode and is not suitable for the case binding mode or the case binding mode, the user mistakenly changes the case binding mode or the case binding mode. It is possible to prevent an erroneous operation by the user such as setting. Or, for example, it is possible to prevent a malfunction or a trouble from occurring in the image forming system due to the user performing such an inappropriate setting. In addition, for example, it is possible to eliminate waste such as creating an output result different from the output result desired by the user.

  However, even when this control is executed (when both the case binding mode and the top binding mode are prohibited), the CPU circuit unit 122, for example, depends on an instruction from the user of the job. The control unit 123, the printer unit 2, and the sheet processing apparatus are controlled so as to permit execution of the print operation of the job to be processed in a state where execution of both the bookbinding processing mode and the top binding mode is prohibited. To do. At this time, the CPU circuit unit 122 uses the operation unit 123 to inquire whether or not to execute the print operation itself, and controls whether to execute only the print operation in response to a reply instruction from the user. You may comprise. In addition, in the user mode or the like, “presence / absence of execution of printing operation in a state in which execution of both the case binding processing mode and the top binding mode is prohibited” is set in advance, and according to the setting, the CPU circuit unit 122 may be configured to control whether or not the printing operation is performed in the above state.

  Thereby, for example, the flexibility and utilization efficiency of the image forming system 1000 and the convenience for the user can be further improved.

  As described above, the CPU circuit unit 122 determines whether the job to be processed satisfies a predetermined condition. When making such a determination, the CPU circuit unit 122 performs processing target information such as the total number of pages of print data included in the job to be processed and various print condition information set by the user for the job. Information related to the job (job attribute information) is used. Also, management information defining various rules to be described later (for example, management information described in various management tables in FIGS. 18, 20, 37, and 38 described later) is also used. Then, a comparison determination process between the job attribute information and the management information is performed.

  In the second case and the third case among the above three cases, the case binding mode and the top binding mode correspond to the sheet processing to be prohibited. However, the sheet processing apparatus 230 according to the present embodiment can execute other types of sheet processing (stapling, punching, saddle stitching, cutting, shift discharge, etc.) other than the gluing processing.

  Therefore, in the present embodiment, for example, even when the execution of the sheet gluing process including the above-described two types of gluing processes is prohibited, the selection and execution of other types of sheet processes are set to the job processing conditions set by the user. Based on this, control is performed by the CPU circuit unit 122 so as to allow it.

  With this configuration, it is possible to further improve the above-described effects such as utilization efficiency and flexibility of the image forming system 1000.

  In addition, as the above-described “determination process for determining whether a job to be processed is a job with a predetermined processing condition”, for example, the CPU circuit unit 122 performs the following processing.

  (Example 1) The CPU circuit unit 122 is for confirming whether or not the total number of sheets used in a job to be processed for which various output processing conditions are set by the user exceeds a first predetermined number. A determination process (hereinafter also referred to as a first determination process) is executed. In accordance with this determination result, whether or not to perform the gluing process on the sheet of the job is determined.

  For example, if the job to be processed is a job that uses more than the first predetermined number of sheets as a result of executing the determination process, the CPU circuit unit 122 adds the sheet of the job to be processed. On the other hand, it is prohibited to execute the case binding process, and it is also prohibited to execute the top binding process. That is, in this case, the CPU circuit unit 122 prohibits execution of both of the two types of sheet gluing processing modes.

  (Example 2) In the present embodiment, the threshold value other than the first predetermined number is the second predetermined number. In addition, the second predetermined number is smaller than the first predetermined number. For example, the first predetermined number is 150 and the second predetermined number is 10.

  Under such a configuration, the CPU circuit unit 122 determines whether or not the total number of sheets used in the job to be processed for which various output processing conditions are set by the user is less than the second predetermined number. A determination process for confirming this (hereinafter also referred to as a second determination process) is executed. In accordance with this determination result, whether or not to perform the gluing process on the sheet of the job is determined.

  For example, as a result of executing the determination process, the job to be processed is a job that uses only less than the second predetermined number of sheets in the image forming apparatus (for example, a job of less than 10 recording sheets). In this case, the CPU circuit unit 122 prohibits the case binding process from being executed on the sheet of the job to be processed.

  In the present embodiment, the second determination process of (Example 2) is executed when the job to be processed corresponds to the job for which the “case binding processing mode” is selected by the user. The CPU circuit unit 122 executes a series of control sequences including the second determination process as shown in (Example 2) when processing a job in which the case binding mode is selected.

  On the other hand, when the job to be processed is a job for which the “sheet binding process mode” is selected, the execution of the second determination process is prohibited. When processing a job for which the top binding mode has been selected, the CPU circuit unit 122 prohibits the execution of the series of control sequences (example 2) including the second determination process.

  However, the series of control sequences including the first determination process in (Example 1) described above is for processing a job for which the case binding mode is selected, even when processing a job for which the case binding mode is selected. However, both cases are controlled to be executed.

  On the premise of the above configuration, the CPU circuit unit 122 further executes control as shown in the following (Example 3) and (Example 4).

  (Example 3) When processing a job for which the case binding mode is selected, the job to be processed corresponds to “a job using the first predetermined number of sheets or less and less than the second predetermined number of sheets”. When the CPU circuit unit 122 determines that “the job does not correspond to a job that uses only a certain number of sheets” (ie, the second predetermined number of sheets ≦ the total number of sheets to be used in the job to be processed ≦ first predetermined number of sheets). Permits the case binding process to be performed on the sheet of the job.

  (Example 4) In the case of processing a job for which the sheet binding mode is selected, the CPU circuit unit determines that the job to be processed corresponds to “a job using the first predetermined number of sheets or less”. If the total number of sheets required for the job is less than the second predetermined number, it is permitted to execute the book binding process on the sheets of the job. To do.

  In addition, it is as follows when description of (Example 1)-(Example 4) is demonstrated in light of the example demonstrated previously.

  As an example of the above-mentioned “job satisfying the first predetermined number”, “a job that requires an output number equal to or smaller than the first predetermined number and requires an output number equal to or larger than the second predetermined number” This is the case. In this case, execution of the case binding mode is permitted. Execution of the book binding mode is also permitted. However, only one of them is allowed to be selected by the user. That is, it is prohibited to select two types of sheet gluing processes at the same time.

  As an example of the above-mentioned “job not satisfying the first predetermined condition but satisfying the second predetermined condition”, “the number of sheets less than the first predetermined number is required and the second predetermined number is satisfied” This corresponds to “a job that requires an output number equal to or less than the number”. In this case, execution of the case binding mode is prohibited. However, the execution of the top glue binding mode is permitted.

  As an example of the above-mentioned “job not satisfying the first predetermined condition and not satisfying the second predetermined condition”, “the number of output sheets exceeding the first predetermined number is required” “Job” corresponds to this. In this case, execution of the case binding mode is prohibited. In addition, execution of the top glue binding mode is also prohibited.

  The relationship is as described above. The reason why such control is adopted is one of the main features of the image forming system, which will be described later.

  As described above, in the image forming system 1000 according to the present embodiment, execution of a predetermined process related to the gluing process that can be executed by the sheet processing apparatus 230 according to whether or not a job to be processed satisfies a predetermined condition. Whether or not (in the above example, execution of various sheet gluing processes themselves) is controlled mainly by the CPU circuit unit 122.

  When the CPU circuit unit 122 performs the determination process as described above (that is, the determination process of whether or not the job to be processed satisfies a predetermined condition), for example, the following determination material is used as the CPU circuit. The unit 122 is used.

  For example, “processing condition data relating to the total number of output jobs to be processed” as described above. The CPU circuit unit 122 compares the information based on this user setting with the management information in the function restriction management table of the management table 3700 shown in FIG. 37 or the management table 3800 shown in FIG.

  In addition, “processing condition data relating to the output sheet of the job to be processed” exists. For example, the processing condition regarding the size information of the sheet to be printed, the processing condition regarding the type of the sheet to be printed, and the like set by the job to be processed by the user correspond to this. The CPU circuit unit 122 compares information based on this user setting with the management information in the management table 1800 shown in FIG.

  There is also “processing condition data relating to the type of sheet processing selected by the user for the job to be processed”. For example, the types of sheet processing set by the user are a plurality of types of sheet processing that can be executed by the sheet processing apparatus 230 (for example, stapling processing, punching processing, cutting processing, shift paper discharge processing, case binding processing, top binding binding) Processing condition data relating to the sheet processing mode set by the user "in the sheet processing and various sheet processes such as saddle stitch binding). The CPU circuit unit 122 compares information based on this user setting with the management information in the management table 1800 shown in FIG.

  The CPU circuit unit 122 acquires various job processing condition information directly related to the job to be processed and set by the user of the job via a user interface unit such as the operation unit 123, for example. Then, based on the job attribute information of the processing target itself based on the user setting and management information managed by the system 1000 itself as shown in FIGS. 18, 20, 37, and 38, the main image formation is performed. Various operations of the system 1000 are controlled.

  In this example, since the job to be processed is a copy mode job, the information is received from the operation unit 123. However, the present embodiment is not limited to this.

  For example, it is assumed that a print job is received via a connector 121 from a host computer connected to the network. In this case, control is performed so that the job is processed based on job processing conditions set by the user of the host computer via a printer driver or the like installed in the host computer that is the data transmission source.

  As described above, if the job is an external job from an external device different from the image forming apparatus (for example, the external device 2002 as shown in FIG. 2), the user interface unit of the external device (if the host computer is a display) The job processing conditions can be set by the user of the external device for the print data of the job to be processed via the mouse, keyboard, etc.

  Therefore, when processing a job received from an external device, the CPU circuit unit 122 determines whether or not the job processing condition information set by the user of the external device associated with the print data of the received job is The image forming system 1000 is controlled.

  In this embodiment, when the image forming system is operated, for example, the CPU circuit unit 122 is configured to execute various prohibition controls (exclusive control) and function restrictions.

  For example, when a predetermined operation mode is selected from among a plurality of operation modes included in the image forming apparatus 1000, selection of another predetermined operation mode is prohibited. In addition, for example, when a certain function is selected, function restriction is performed such that another function can be used in combination within a certain restriction range.

  In the present embodiment, when performing such control, management information data for prescribing various functions and operation rules in the image forming system (for example, as shown in FIG. 18, FIG. 20, FIG. 37, and FIG. 38). Such management information defining various rules) is stored in an appropriate memory such as the image memory 120 or the ROM 124 in the form of a table, for example.

  The CPU circuit unit 122 uses such management data as various judgment materials when processing a job.

  When a job from an external apparatus is processed by the image forming system 1000, all or part of various controls executed by the CPU circuit unit 122 described in the present embodiment is transferred to the external apparatus. A control unit (for example, a CPU of the host computer if the external device is a host computer) is configured to execute.

  With this configuration, not only when the job from the reader unit 1 is processed by the image forming system 1000, but also when the job from the external apparatus is processed by the image forming system 1000, various effects described in the present embodiment can be achieved. There is an effect that can be done.

  Here, with reference to FIG. 8, the glue binding process in the present embodiment will be described.

  FIG. 8 is a schematic diagram for explaining gluing bookbinding in the present embodiment.

  The sheet processing apparatus 230 included in the image forming system 1000 according to the present exemplary embodiment includes a plurality of types of sheet processing (stapling processing, punching processing, shift paper discharge processing, saddle stitch binding processing, cutting processing, and gluing bookbinding processing) including glue binding processing. Etc.) is configured to be executable.

  In addition, the sheet processing apparatus 230 of the present embodiment can execute a plurality of types of sheet gluing processes including at least two types of different types of first type gluing bookbinding processing and second type gluing bookbinding processing. It is configured.

  For example, the image forming system 1000 according to the present exemplary embodiment is configured such that a “case binding process” can be executed by the sheet processing apparatus 230 as the first type of glue binding process. In the case binding process, the image forming system is controlled by the CPU circuit unit 122 so that an output product as shown in FIG.

  When a case binding target job is processed by the image forming system 1000, the following series of processing operations are executed by the image forming system 1000.

  For example, a series of print data of a job input from the reader unit 1 or a series of print data of a job received from an external device via the connector 121 is stored in the hard disk of the image memory 120. In addition, a predetermined type of sheet (referred to as a first type of sheet) designated by the user as a body sheet in case binding of the job includes a plurality of sheet feeding units (214, 215) included in the image forming apparatus main body. 225, 226, 227), the paper is fed from the paper feeding unit based on the instruction from the user. Next, the printer unit 2 causes the printer unit 2 to print the text print data in the case binding process of the job read from the image memory 120 on the first type sheet from the sheet feeding unit. The example of FIG. 8A is an example in which the image data for text is printed on both sides of a plurality of sheets for text.

  Further, in the case binding process, a gluing unit 300 is attached to a sheet bundle composed of a plurality of body sheets printed with body print data (this sheet bundle is referred to as a first type sheet bundle). To execute the gluing process. In this gluing process, a plurality of text sheets (first type sheets) are glued together.

  Next, in the case binding process, the first type sheet bundle that has been subjected to the gluing process (that is, a series of sheet bundles composed of a plurality of text sheets on which image data for the text is printed) and case binding. A predetermined type of sheet (referred to as a second type of sheet) designated by the user as a cover sheet is glued by the gluing unit 300 as one output bundle. The example shown in the middle in FIG. 8A is a case binding cover sheet (this sheet corresponds to a second type sheet).

  In this embodiment, the first type sheet bundle (corresponding to the sheet bundle on which the text image is printed) and the second type sheet (covering the text sheet bundle are used in any method. It is also possible to execute a gluing process with a bookbinding cover sheet.

  However, in the end, the image is subjected to the sheet gluing process so that an output result as shown at the right end of FIG. 8A or a printed material 2400 as shown in FIGS. Control the forming system 1000.

  Further, in the image forming system 1000 of the present embodiment, the second type sheet (corresponding to a case binding cover sheet) is supplied to a plurality of paper feeding units (214, 215, 225, 226) provided in the main body of the image forming apparatus. 227), the sheet can be fed from the sheet feeding unit designated by the user and conveyed into the sheet processing apparatus 230.

  The printer unit 2 can print image data for case binding cover on the second type sheet (corresponding to a case binding cover sheet). The middle example in FIG. 8A is an example of the case binding cover image data printed on the case binding cover sheet by the printer unit 2.

  Of course, a sheet on which image data for case binding cover is printed in advance can be used for the second type sheet (sheet for case binding cover). In this case, if the user sets a sheet on which image data for case binding cover has been printed in the sheet feeding unit, the printer unit 2 does not need to execute the printing process. Therefore, in this case, the image forming system 1000 is controlled so that the printer unit 2 does not perform printing, and conveys the second type sheet into the sheet processing apparatus 230 as it is.

  As described above, when a sheet on which an image has been printed in advance is used as the second type sheet, a special sheet can be transported into the sheet processing apparatus 230 without passing through the printer unit 2. A feeding device (in this embodiment, such a paper feeding device is called an inserter) may be provided. If the second type sheet is a preprinted sheet, the present image forming system may be constructed so that the sheet can be fed from the inserter.

  In the present embodiment, an operation screen for allowing the user himself to decide whether or not to print the cover image data in the case binding process on the second type sheet is displayed on the display unit 4-250. Is controlled by the CPU circuit unit 122 so as to be displayable. The user can select whether or not to execute printing on the second type sheet in the case binding mode via the screen or the like.

  In the present embodiment, the relationship between the first type sheet and the second type sheet in the case binding process will be described.

  In the present embodiment, the first type sheet and the second type sheet have different sheet types and different sheet sizes. Alternatively, the first type sheet and the second type sheet may be the same or different, but the sheet size is different. That is, in the case binding mode, which is described in detail in the present embodiment, the first type sheet and the second type sheet mean at least sheets having different sizes. In particular, in the present embodiment, the second type sheet is a sheet having a larger size than the first type sheet.

  In the gluing process between the first type sheet bundle and the second type sheet, the following gluing process is performed.

  For example, a second type sheet on which image data for case binding covers is printed on a first sheet bundle in which image data for body text is printed and glued to the back cover part is used for the first type sheet bundle. Gluing is performed so that the second type sheet (one sheet) is covered around the spine portion. Finally, a process of folding the second type sheet around the spine portion is executed. This output result example corresponds to a print result example on the right side of FIG. 8A or a print result example shown in FIGS.

  As described above, the image forming system 1000 according to the present embodiment is configured such that the case binding process can be executed by the sheet processing apparatus 230 as the first type of sheet gluing process.

  Next, a second type of sheet gluing process that can be executed by the image forming system, which corresponds to a different type of gluing process from the first type of gluing process, will be described.

  For example, the image forming system 1000 of the present embodiment is configured to be able to execute a “top glue binding process” as the second type of glue binding process.

  In the present embodiment, when processing a job to be bound by the top glue using the image forming system 1000, for example, the following series of processing operations are executed by the CPU circuit unit 122 in the image forming system 1000. Let

  First, a series of print data of a job input from the reader unit 1 or a series of print data of a job received from an external device via the connector 121 is stored in the hard disk of the image memory 120. On the other hand, a plurality of sheet feeding units provided in the main body of the image forming apparatus include a predetermined type of sheet (corresponding to a first type of sheet) designated by the user as a body sheet in the book binding of the job. Out of (214, 215, 225, 226, 227), the sheet is fed from the sheet feeding unit based on the instruction from the user. Then, the printer unit 2 causes the printer unit 2 to print text data for the first type sheet from the sheet feeding unit in the top-sheet binding process of the job read from the image memory 120. The example of FIG. 8B is an example in which image data for text is printed on both sides of a plurality of sheets for text.

  Further, in the top glue binding process, the gluing process is performed so that the gluing process is performed on a sheet bundle (corresponding to the first type sheet bundle) composed of a plurality of text sheets on which print data for the text is printed. The unit 300 is controlled.

  The above processing is basically the same as the “case binding processing” described above. However, when the “sheet binding process” is executed, the CPU circuit unit 122, for example, executes the present image forming system so as to prohibit the following process among the processes executed in the “case binding process”. 1000 is controlled.

  For example, in the sheet binding process, the CPU circuit unit 122 prohibits the use of a cover sheet (corresponding to a second type sheet). Specifically, the CPU circuit unit 122 performs control so as to prohibit the gluing of the second type sheet to the first sheet bundle on which the image data for text is printed in the top glue binding processing mode. . In addition, the CPU circuit unit 122 supplies the second type sheet to be used in the case binding mode in the processing of the job to be processed in the top glue processing mode (214, 215, 225, 226, 227) is also prohibited. Naturally, the CPU circuit unit 122 also prohibits the printing process for the second type sheet in the top-bound binding mode.

  The example on the right side of FIG. 8B shows an example of the final product created by this top glue binding process. The top glue binding process and the case binding process described above are controlled so that the gluing process method is different.

  For example, this is the same as case binding in that the first type of sheet bundle (corresponding to a sheet bundle made up of a plurality of sheets printed with text image data) is executed. However, it is prohibited to execute the second-type sheet gluing process (see FIG. 8A) to be executed in the case binding process mode in the top-binding process mode. In the sheet binding process, as shown in FIG. 8B, the CPU circuit unit 122 controls the sheet processing device 230, the printer unit 2, and the like so that the gluing process is completed only with the sheet bundle for the text.

  As described above, the image forming system is configured so that the sheet processing apparatus 230 can execute the top glue binding process as a second type of gluing process different from the first type of gluing process.

  Based on the above configuration, the image forming system 1000 according to the present exemplary embodiment includes a case binding processing mode and a user interface unit (in the present exemplary embodiment, the display unit 4-250 and the operation unit 123). Of the sheet binding processing modes, the user can select a desired gluing processing mode by the user himself / herself. The CPU circuit unit 122 controls the image forming system so as to execute the gluing process corresponding to the processing mode selected by the user among the two types of gluing process modes.

  Next, various processes related to “case binding” corresponding to the gluing processing mode for attaching a cover described with reference to FIG. 8A will be further described with specific examples.

  FIGS. 24 to 35 are explanatory diagrams regarding “case binding processing” as an example of sheet gluing processing to be controlled in this embodiment, and the same components are denoted by the same reference numerals.

  Here, it is assumed that the data generation source of the job to be subjected to the case binding process is the reader unit 1 of its own apparatus. A series of processing procedures in the case where the original set on the reader unit 1 is printed and the sheet printed by the sheet processing apparatus 230 on the sheet printed by the printing process will be described.

  First, it is assumed that the application mode key 4-260 on the screen of FIG. 4 displayed on the display unit 4-250 of the operation unit 123 is pressed by the user. In response to this, the CPU circuit unit 122 causes the display unit 4-250 to display the screen of FIG. Next, it is assumed that the “bookbinding mode” is selected by the user via the key 801 on the screen of FIG. In response to this, the CPU circuit unit 122 displays the screen in FIG. 6B and then displays the screen in FIG. 6C on the display unit 4-250.

  Then, a “glued bookbinding” instruction is input by the user via the key 803 on the screen of FIG. 6C, and “cover setting” is made by the user via the screen of FIG. Suppose.

  As described above, when the glue binding mode is selected by the user, when the user instructs the setting of attaching a cover to the sheet on which the text image data is printed, the CPU circuit unit 122 displays the user setting. The job to be processed in accordance with the process is determined to be a “job to execute the case binding process”. That is, in this example, the CPU circuit unit 122 executes the case binding processing mode on condition that the glue binding mode is selected by the user and the setting of “attach cover” is selected by the user. It is determined that the job is to be performed.

  It is assumed that the user has set various print processing conditions for the job to be processed. Then, it is assumed that the start key 4-242 of the operation unit 123 in FIG. 4 is pressed by the user. At this point, the CPU circuit unit 122 determines that a job processing start request instruction has been input. Then, based on an instruction from the user, the document bundle placed on the document feeder 101 of the reader unit 1 by the user is sequentially read from the first page one by one to the reading position on the platen glass of the reader unit 1. The reader unit 1 is controlled by the CPU circuit unit 122 so that the document is fed and the reading process of the original of the job is executed by the reader unit 1. In addition, the CPU circuit unit 122 controls the image memory 120 and the like so that the read data is sequentially stored in the hard disk of the image memory 120 as text data (contents) in the case binding process.

  The result of printing the stored data corresponds to, for example, “double-sided printing for text” in FIG. In FIG. 8A, the output result for the text is “double-sided printing”. However, in case binding processing, it is not always necessary to execute double-sided printing on a sheet on which a text image is printed. This is because, in the case binding printing mode, there are various user needs such as a user who wants to double-side print a part corresponding to the text and a user who prints a part corresponding to the text on one side.

  Therefore, for example, in the case of bookbinding in the image forming system 1000, whether to perform single-sided printing or double-sided printing on a sheet (corresponding to a first type sheet) for printing a text image is displayed on the screen of FIG. You may comprise so that selection decision determination by the user himself / herself via the key 4-258 is possible.

  Further, in this embodiment, a cover sheet for the case binding process (corresponding to a second type sheet) is set by the user, for example, in the manual sheet feeder 227 of the image forming apparatus. In addition, in order to select the second type sheet, when a user selects a cover sheet via the display unit 4-250, a sheet feeding unit corresponding to the manual sheet feeding unit 227 can be selected. To do. Accordingly, the second type sheet can be fed from the manual sheet feeding unit.

  Further, in this image forming apparatus or another printing apparatus, image data for case binding cover is printed in advance on the cover sheet for case binding processing. Then, the user sets the sheet on which the cover display image has been printed on the paper feeding unit of the image forming apparatus prior to processing the case binding processing target job in the image forming system. . The processing conditions are set by the user via the operation unit 123 so as to use this sheet. As a result, when processing the case binding process target job, it is not necessary to execute print processing on the case binding cover sheet.

  When a sheet that has already been printed is used as the second type sheet and the image forming system 1000 includes the inserter as described above, the second type sheet is supplied from the inserter. You may comprise so that sending is possible. In this case, the CPU circuit unit 122 controls the display unit 4-250 to display a display screen that allows the inserter to be selected as the second type sheet feeding unit. Then, via the screen, the inserter can be selected by the user as the second type sheet feeding source.

  As described above, in the case where the image data for the cover is already printed on the second type sheet, in the present embodiment, the job of which the reading operation is executed by the reader unit 1 is described. The read image data is document image data for all pages and text.

  On the other hand, in a series of processing steps of a job to execute case binding processing, when processing for printing image data for a cover on a cover for case binding is necessary, the CPU circuit unit 122 is as follows. The processing is executed by the image forming apparatus.

  For example, it is assumed that the case binding mode is selected by the user via the operation unit 123 and an instruction to print a cover image on a sheet corresponding to a second type sheet serving as a cover is input.

  In this case, the CPU circuit unit 122 uses the image data corresponding to the document image of the first page of a series of document bundles composed of a plurality of pages read by the reader unit 1 as a cover document image on the hard disk of the image memory 120. To store. Next, the original image data of a page subsequent to the page (for example, the second and subsequent pages) is sequentially stored in the hard disk in association with the image data for the cover as original document image data. .

  In a case binding job, a cover cover image is printed on a portion that becomes a cover of a case binding cover sheet (corresponding to a second type sheet), and a portion that becomes the back cover of the sheet. You can also print image data for the back cover. In order to deal with such a user who desires processing, the CPU circuit unit 122 may execute the following control.

  For example, when the user executes cover setting on the display unit 4-250, the user inputs an instruction such as “print both the front cover image and the back cover image on the case binding cover sheet”. A display screen having a display key to be enabled is displayed on the display unit 4-250. In response to the input of the instruction via the screen, the printer unit 2 is controlled to execute the above-described processing.

  When such a setting is made, image data corresponding to the original of the first page in a series of original bundles composed of a plurality of pages read by the reader unit 1 is used as an image memory 120 for the front cover. Stored on the hard disk. Further, the image data corresponding to the second page original of the job is stored in the hard disk of the image memory 120 as the back cover original image. Then, the original image data corresponding to the remaining pages of the job is stored in the hard disk in association with the image data for the front cover and the image data for the back cover as original document image data.

  When the case binding mode is selected, for example, when a series of original pages consisting of 10 pages are continuously read by the reader unit 1, the original read first is the second type sheet (for cover). This image data is registered in the image memory 120 as image data for the front cover to be printed. Next, the image data of the first to eighth pages for the text to be printed on the first type sheet (corresponding to the sheet for the text) is used as the second to ninth read original data. To register. Then, the last read tenth original is registered in the image memory 120 as image data for the back cover to be printed on the first type sheet. Then, the CPU circuit unit 122 manages these image data in association with each other. Thus, a data storage method may be used in which the document image data for the back cover is registered at the end of the document bundle. That is, the configuration may be such that all the case binding process printing is completed and the image data to be processed is registered in the image memory 120 in the same order as the page order of the final case binding printed matter.

  However, this embodiment employs the above control example from the viewpoint of improving usability, but the present embodiment is not limited to this. For example, any configuration is possible as long as the following control can be executed by the image forming system 1000.

  For example, out of a series of image data consisting of a plurality of pages to be processed, document image data corresponding to the data for the front cover and document image data corresponding to the data for the back cover are the second type sheets (cases). Control is performed so that printing is performed on the same surface (corresponding to a cover sheet in bookbinding processing). Then, a plurality of pages of document image data corresponding to the text data in the series of image data are printed on a plurality of first type sheets (corresponding to the text sheets in the case binding process). As described above, the CPU unit 122 controls the reader unit 1, the image memory unit 120, the printer unit 2, and the like. Then, print data desired by the user as a cover image for case binding is printed on the cover sheet for case binding, and the print data desired by the user as a text image for case binding is displayed on the text sheet. It is configured so that it can be printed.

  If such a configuration can be realized, the reading order of the originals by the reader unit 1, the order of storing the original image data in the image memory 120, the reading order of the original image data from the image memory 120, and the printer unit 2 Various operation sequences such as the print order of document image data are not limited. The same applies to print data of a case binding target job received from an external device (for example, 2002 in FIG. 2).

  Further, in the apparatus or system capable of executing the sheet gluing process, such as the image forming system 1000, it is possible to further respond to various user needs from various users related to the gluing process. In order to further improve, the above control may be further applied in the present embodiment.

  For example, the CPU circuit unit 122 of the image forming system of the present embodiment controls the image forming system 1000 so as to execute the following processing.

  For example, when the case binding mode is selected by the user via the display unit 4-250, the display screen in FIG. 7F is displayed on the display unit 4-250.

  In the present embodiment, when a case binding process target job is processed, a paper surface corresponding to a front cover page in a case binding printed material (see, for example, a case binding printing result 2400 shown in FIG. 24A). In the example of FIG. 24, for a region 2401), first predetermined print data (in the present embodiment, this is different from the case print data in the case cover product), which is different from the text print data in the case binding print product. Whether or not to print the image data for the front side) can be set by the user via the display screen having various display keys shown in FIG.

  For example, when the user presses the “Copy to Front Cover” key on the display screen of FIG. 7F, the cover in the case binding printing result (here, the front cover is the case binding printing). The image data for the cover in the case binding print is printed on the page corresponding to the page of the page (described in the example of FIG. 24A). 2 to print. On the other hand, for example, when the “Do not copy to front cover” key on the screen of FIG. 7F is pressed, the printer unit 2 applies the paper surface corresponding to the cover page in the case binding print result. Printing the first predetermined print data is prohibited.

  As described above, the image forming system 1000 enables the first special printing process in the case binding mode.

  Furthermore, in the present embodiment, the case binding printed matter is viewed from the upright state, and the page corresponding to the page immediately after the user turns only one cover from the front cover side (for example, using FIG. 24C). For example, the second predetermined print data (corresponding to the area 2403), which does not correspond to the print data for the text in the case binding printed material (in the embodiment, this is the case). Whether or not to print the image data for the back of the front cover in the bookbinding product can be set by the user via the display screen having various display keys of FIG.

  For example, when the user presses the “copy to cover cover” key on the display screen of FIG. 7F, the case binding print result is viewed from the front cover side only in the case of the case binding printing result. Image data for the back of the front cover of the case binding printed material for the paper surface corresponding to the page immediately after the user turned over (for example, the area 2403 in FIG. 24C). Is printed by the printer unit 2. On the other hand, for example, when the “Do not copy to cover cover” key on the screen of FIG. 7F is pressed, the page corresponding to the page immediately after turning the cover in the case binding print result is displayed. Execution of the print processing of the second predetermined print data by the printer unit 2 is prohibited.

  As described above, the image forming system 1000 enables the second special printing process in the case binding mode.

  Further, in the present embodiment, when the case binding printed material is viewed from the upright state, the user turns only one back cover from the back cover side and corresponds to the page immediately after turning (for example, FIG. 24). In the case of (d), the third predetermined print data (this embodiment is not applicable to the print data for the text in the case binding printed material) as in the previous case. In the embodiment, this is referred to as image data for the front cover of the back cover in case binding) by the user via the display screen having various display keys shown in FIG. Make it configurable.

  For example, when the “copy to the back cover front” key on the display screen in FIG. 7F is pressed by the user, the case binding printed material is viewed from the upright state, and only the back cover is viewed from the back cover side. A front cover front image in case binding on a paper surface corresponding to a page immediately after the user turns only one sheet (for example, the area 2404 in FIG. 24D). Data is printed by the printer unit 2. On the other hand, when the “Do not copy to back cover front” key on the screen of FIG. 7F is pressed, the page corresponding to the page immediately after turning the back cover from the back cover side in the case binding printing result. On the other hand, the printer unit 2 is prohibited from executing the print processing of the third predetermined print data.

  As described above, the image forming system 1000 enables the third special printing process in the case binding mode.

  Further, in the present embodiment, the paper surface corresponding to the back cover page in the case-bound printed matter (for example, corresponding to the area 2402 in FIG. 24B) is the same as the previous case. Whether to print fourth predetermined print data (in the present embodiment, this is referred to as image data for the front surface of the case cover) that is not used by the user as the text print data for case binding prints. Can be set by the user via the display screen having various display keys shown in FIG.

  For example, when the user presses the “copy to back cover back” key on the display screen of FIG. 7F, the paper surface corresponding to the back cover page in the case binding print result (for example, FIG. When using b), the image data for the back cover in the case binding print is printed by the printer unit 2 for the area 2402). On the other hand, for example, when the “Do not copy to back cover back” key on the screen of FIG. 7F is pressed, the printer unit 2 applies to the paper surface corresponding to the back cover page in the case binding print result. Thus, the printing of the fourth predetermined print data is prohibited.

  As described above, the image forming system 1000 enables the fourth special printing process in the case binding mode.

  As described above, in the image forming system of the present embodiment, when the case binding mode is processed by the image forming system 1000 in a case where the case binding mode is set by the user, the main sheet (first type sheet) is processed. The printer unit 2 is not limited to executing a series of printing processes for image data for text. Note that a series of processes for printing the text print data on the text sheet (first type sheet) is called the first print mode in the case binding mode (or the first print sequence in the case binding mode). Called).

  In the image forming system 1000 of the present embodiment, not only can the first print mode in the case binding mode be executed in a case binding job, but also the user can use the mode as image data for text. Is a special series of print processing (at least four kinds of special print sequences in the above example) including at least a print processing for the case binding sheet of predetermined print data corresponding to data not handled. The image forming system is controlled by the CPU circuit unit 122 so as to be executable. Note that a series of print processing of the predetermined print data that does not correspond to the text print data is referred to as a second print mode in the case binding mode (or referred to as a second print sequence in the case binding mode).

  In addition, as described above, the first print sequence is performed in the case binding mode by controlling the screen such as the display screen of FIG. 7F by the CPU circuit unit 122 so as to be displayed on the user interface unit. The user who has selected the case binding mode can select whether to execute both the first print sequence and the second print sequence or only the first print sequence.

  By using the first print sequence and the second print sequence, for example, catalogs and manuals for certain new products, training materials for companies with a certain volume, guidebooks for public organizations, etc. Various kinds of various bookbinding products of various types and various layouts can be created by the image forming system. For example, as an example, five types of case binding printing processes that can be executed by the image forming system 1000 will be described with reference to FIGS.

  In the above example, in the case binding mode, there are four predetermined print data that do not correspond to the print data for the text.

  Therefore, in the description using FIGS. 25 to 35, the first predetermined print data is the image A. Similarly, the second predetermined print data is an image C. Similarly, the third predetermined print data is an image D. Similarly, the fourth print data is an image B here. Further, it is assumed that the print data for the text in the “case binding mode” in this example exists for a total of M pages.

  The first to fourth predetermined print data images A to D and the text print data (print data for a total of M pages from the first page to the M page) are received from the reader unit 1 or the external device 2002. Entered. These data are associated as one job and stored in the hard disk of the image memory 120.

  As such a premise, for example, it is assumed that the user executes the following series of settings as settings for a job to be processed.

  First, the first example will be described. When the user presses the “Copy to Front Cover” key on the setting screen in FIG. 7F, the image A is printed in the second type sheet area 2401 in the case binding mode. An instruction to execute the first special printing process was input.

  In addition, when the user presses the “copy to cover cover” key on the setting screen of FIG. 7F, the image C is printed in the area 2403 of the second type sheet in the case binding mode. Therefore, the execution instruction for the second special printing process is input.

  In addition, when the user presses the “copy to the back cover front” key on the setting screen of FIG. 7F, the image D is printed in the area 2404 of the second type sheet in the case binding mode. In order to do this, the execution instruction for the third special printing process described above was input.

  In addition, when the user presses the “Copy to Back Cover Back” key on the setting screen of FIG. 7F, the image B is printed in the area 2402 of the second type sheet in the case binding mode. In order to do this, the execution instruction for the fourth special printing process described above was input.

  In response to a series of print settings in the case binding mode as described above being executed by the user via the operation unit 123, the CPU circuit unit 122 displays a case print binding result 2400 as shown in FIG. The case binding print target job is processed by the image forming system 1000 so as to be created.

  Note that the way of referring to the print results 2400 in FIGS. 25A to 25D is the same as the way of referring to the print results 2400 in FIGS.

  That is, the CPU circuit unit 122 causes the printer unit 2 to execute the following two types of printing processes as the case binding printing process in the case binding mode in order to obtain the printing result 2400 shown in FIG.

  First, as the first print sequence in the case binding print job, the text print data included in the data of the case binding print target job stored in the hard disk of the image memory 120 is used as the first type sheet. On the other hand, the printer unit 2 is controlled to print. This series of printing operations is executed for the number of pages for the text. In this example, print processing for a total of M pages is executed.

  Further, the CPU circuit unit 122 not only executes the first print sequence, but also associates the image with the print data for the text of the case binding print job as the second print sequence in the case binding print job. The printer unit 2 is configured to print the four predetermined print data of the image A, image B, image C, and image D stored in the hard disk of the memory 120 in the areas 2401 to 2404 of the second type sheet. To control.

  In creating the print result 2400 shown in FIG. 25, the CPU circuit unit 122 causes the following print processing to be executed in a series of printing steps for the second type sheet.

  The state of the second type sheet before being glued to the first type sheet bundle on which the print data for the text is printed is in a state before being folded in half as shown in FIG.

  In order to obtain a printing result as shown in FIG. 25, the CPU circuit unit 122 causes the printer unit 2 to execute a printing process as shown in FIG.

  That is, the second type sheet is arranged so that the image A is arranged in the area 2401 on the first surface of the second type sheet and the image B is arranged in the area 2402 on the first surface of the second type sheet. The printer unit 2 is caused to execute print processing for the first surface of the sheet.

  The CPU circuit unit 122 executes layout processing using a memory that can be used for image editing processing so that the image A and the image B become data for one page, and then the image A and the image B are processed. The image data obtained by editing B with image data for one page is printed on the first surface of the second type sheet by the printer unit 2.

  In addition, the image C is arranged in the area 2403 on the second surface (the back side of the first surface) of the second type sheet, and the image D is arranged in the area 2404 on the second surface of the second type sheet. As described above, the printer unit 2 is caused to execute print processing for the second surface of the second type sheet.

  The CPU circuit unit 122 executes the layout process using a memory that can be used for the image editing process so that the image C and the image D become data for one page, and then the image C and the image D are processed. The image data obtained by editing D into image data for one page is printed by the printer unit 2 on the second surface of the second type sheet.

  A series of print processes for the second type sheet as described above are executed. After that, the second type of the second type that has undergone the printing process is applied to the first type of sheet bundle composed of a plurality of first type sheets on which the print data for the body (print data for a total of M pages) is printed. The sheet is subjected to a gluing process by the gluing unit 300.

  As a result, a case binding print 2400 as shown in FIG. 25 can be created by the image forming system 1000.

  Next, a second example will be described. For example, assume that the user performs the following series of print settings on the setting screen of FIG.

  First, when the user presses the “Copy to Front Cover” key on the setting screen of FIG. 7F, the image A should be printed on the area 2401 of the second type sheet in the case binding mode. The execution instruction for the first special printing process is input.

  However, in the case binding mode, by pressing the “Do not copy to cover cover” key on the setting screen of FIG. The execution prohibition instruction for the second special printing process is input so that the image C is not printed in the sheet area 2403.

  In addition, in the case binding mode, by pressing the “Copy to back cover front” key on the setting screen of FIG. 7F, the “Do not copy to back cover front” key is pressed. The instruction to prohibit execution of the third special printing process is input so that the image D is not printed in the area 2404 of the second type sheet.

  However, when the user presses the “Copy to Back Cover Back” key on the setting screen of FIG. 7F, the image B is printed in the area 2402 of the second type sheet in the case binding mode. Therefore, the execution instruction for the fourth special printing process is input.

  In response to the series of print settings in the case binding mode as described above being executed by the user via the operation unit 123, the CPU circuit unit 122 displays a case print binding result 2400 as shown in FIG. The case binding print target job is processed by the image forming system 1000 so as to be created.

  Note that the way of referring to the print results 2400 in FIGS. 26A to 26D is the same as the way of referring to the print results 2400 in FIGS.

  That is, the CPU circuit unit 122 causes the printer unit 2 to execute the following two types of printing processes as the case binding printing process in the case binding mode in order to obtain the printing result 2400 shown in FIG.

  First, as the first print sequence in the case binding print job, the print data for the text of the case binding print target job data in the hard disk of the image memory 120 (for a total of M pages) is used as the first type sheet. On the other hand, the printer unit 2 is controlled to print.

  In addition, the CPU circuit unit 122 not only executes the first print sequence, but also uses the case binding print job as a second print sequence in association with the print data for the text of the case binding print job. The printer unit 2 is controlled so that two predetermined print data stored in the memory 120, that is, the image A and the image B are printed on the areas 2401 and 2402 of the second type sheet, respectively. .

  In creating the print result 2400 shown in FIG. 26, the CPU circuit unit 122 causes the following print processing to be executed in a series of printing steps for the second type sheet.

  The state of the second type sheet before being glued to the first type sheet bundle on which the print data for the text is printed is in a state before being folded in half as shown in FIG.

  In order to obtain a printing result as shown in FIG. 26, the CPU circuit unit 122 causes the printer unit 2 to execute a printing process as shown in FIG. That is, the second type sheet is arranged so that the image A is arranged in the area 2401 on the first surface of the second type sheet and the image B is arranged in the area 2402 on the first surface of the second type sheet. The printer unit 2 is caused to execute print processing for the first surface of the sheet.

  The image A and the image B are subjected to layout processing using a memory that can be used for image editing processing so as to become data for one page, and then the printer unit 2 uses the second type sheet. The first side is printed.

  However, in this print sequence, the image C is arranged in the region 2403 on the second surface (back side of the first surface) of the second type sheet, and the image D is displayed in the region 2404 on the second surface of the second type sheet. Execution by the printer unit 2 of the printing process for the second surface of the second type sheet such that is disposed is controlled to be prohibited.

  As described above, in the second example, the CPU circuit unit 122 controls the printer 2 to execute the printing process so that the image A and the image B are printed on the first surface of the second type sheet. To do. However, control is performed to prohibit the execution of a print process in which the image C and the image D are laid out on the second surface of the second type sheet.

  A series of print processes for the second type sheet as described above are executed. Then, the second print-processed second sheet is formed on the first-type sheet bundle composed of a plurality of first-type sheets on which print data for the body (print data for a total of M pages) is printed. The sheet of the type is subjected to a gluing process by the gluing unit 300.

  As a result, a case binding print 2400 as shown in FIG. 26 can be created by the image forming system 1000.

  Next, a third example will be described. For example, assume that the user performs the following series of print settings on the setting screen of FIG.

  First, when the user presses the “Copy to Front Cover” key on the setting screen of FIG. 7F, the image A should be printed on the area 2401 of the second type sheet in the case binding mode. The execution instruction for the first special printing process is input.

  However, the “Copy to back cover front” key on the setting screen of FIG. 7F is not pressed, and the “Do not copy to back cover front” key is pressed in the case binding mode. The execution prohibition instruction for the third special printing process described above is input so that the image D is not printed in the area 2404 of the two types of sheets.

  However, when the user presses the “Copy to Back Cover Back” key on the setting screen of FIG. 7F, the image B is printed in the area 2402 of the second type sheet in the case binding mode. Therefore, the execution instruction for the above-described fourth special printing process was input.

  In response to a series of print settings in the case binding mode as described above being executed by the user via the operation unit 123, the CPU circuit unit 122 displays a case print binding result 2400 as shown in FIG. The case binding print target job is processed by the image forming system 1000 so as to be created.

  Note that the way of referring to the print results 2400 in FIGS. 27A to 27D is the same as the way of referring to the print results 2400 in FIGS.

  That is, the CPU circuit unit 122 causes the printer unit 2 to execute the following two types of printing processes as the case binding printing process in the case binding mode in order to obtain the printing result 2400 shown in FIG.

  The state of the second type sheet before being glued to the first type sheet bundle on which the print data for the text is printed is in a state before being folded in half as shown in FIG.

  In order to obtain a printing result as shown in FIG. 27, the CPU circuit unit 122 causes the printer unit 2 to execute a printing process as shown in FIG. That is, the CPU circuit unit 122 arranges the image A in the area 2401 on the first surface of the second type sheet and the image B in the area 2402 on the first surface of the second type sheet. In addition, the printer unit 2 is caused to execute print processing for the first surface of the second type sheet.

  The image A and the image B are subjected to layout processing using a memory that can be used for image editing processing so as to become data for one page, and then the printer unit 2 uses the second type sheet. The first side is printed.

  In addition, the CPU circuit unit 122 arranges the image C in the region 2403 on the second surface (back side of the first surface) of the second type sheet, provided that the region 2404 on the second surface of the second type sheet. The printer unit 2 is caused to execute a printing process on the second surface of the second type sheet so that the image D is not arranged in the printer 2.

  As described above, in the print sequence, the printing process of the image C for the area 2403 on the second surface of the second type sheet is permitted, but the printing process of the image D for the area 2404 on the second surface of the second type sheet. Control to prohibit.

  As described above, in the third example, the CPU circuit unit 122 controls the printer 2 to execute print processing so that the image A and the image B are laid out on the first surface of the second type sheet. To do. Then, printing is also permitted so that the image C is laid out on the second surface of the second type sheet. However, control is performed so as to prohibit the execution of a printing process in which the image D is laid out on the second surface of the second type sheet.

  A series of print processes for the second type sheet as described above are executed. Then, the second print-processed second sheet is formed on the first-type sheet bundle composed of a plurality of first-type sheets on which print data for the body (print data for a total of M pages) is printed. The sheet of the type is subjected to a gluing process by the gluing unit 300.

  As a result, a case binding print 2400 as shown in FIG. 27 can be created by the image forming system 1000.

  Next, a fourth example will be described. For example, assume that the user performs the following series of print settings on the setting screen of FIG.

  First, when the user presses the “Copy to Front Cover” key on the setting screen of FIG. 7F, the image A should be printed on the area 2401 of the second type sheet in the case binding mode. The execution instruction for the first special printing process is input.

  However, in the case binding mode, the second type is not pressed by pressing the “Copy to cover page back” key on the setting screen of FIG. 7F but by pressing the “Do not copy to cover page back” key. The execution prohibition instruction for the second special printing process is input so that the image C is not printed in the area 2403 of the sheet.

  However, when the user presses the “copy to back cover front” key on the setting screen of FIG. 7F, the image D is printed in the area 2404 of the second type sheet in the case binding mode. As described above, the execution instruction for the third special printing process is input.

  Similarly, when the user presses the “copy to back cover back” key on the setting screen in FIG. 7F, the image B is printed in the area 2402 of the second type sheet in the case binding mode. In order to do so, an instruction to execute the above-described fourth special printing process is also input.

  In response to a series of print settings in the case binding mode as described above being executed by the user via the operation unit 123, the CPU circuit unit 122 displays a case print binding result 2400 as shown in FIG. The case binding print target job is processed by the image forming system 1000 so as to be created.

  Note that the method of referring to the print results 2400 in FIGS. 28A to 28D is the same as the method of referring to the print results 2400 in FIGS.

  That is, the CPU circuit unit 122 causes the printer unit 2 to execute the following two types of printing processes as the case binding printing process in the case binding mode in order to obtain the printing result 2400 shown in FIG.

  First, as the first print sequence in the case binding print job, the print data for the text of the case binding print target job data in the hard disk of the image memory 120 (for a total of M pages) is used as the first type sheet. On the other hand, the printer unit 2 is controlled to print.

  In addition, the CPU circuit unit 122 not only executes the first print sequence, but also uses the case binding print job as a second print sequence in association with the print data for the text of the case binding print job. Three predetermined print data stored in the memory 120, that is, the image A, the image B, and the image D are printed on the region 2401, the region 2402, and the region 2404 of the second type sheet, respectively. The printer unit 2 is controlled.

  The state of the second type sheet before being glued to the first type sheet bundle on which the print data for the text is printed is in a state before being folded in half as shown in FIG.

  In order to obtain a printing result as shown in FIG. 28, the CPU circuit unit 122 causes the printer unit 2 to execute a printing process as shown in FIG.

  That is, the CPU circuit unit 122 arranges the image A in the area 2401 on the first surface of the second type sheet and the image B in the area 2402 on the first surface of the second type sheet. In addition, the printer unit 2 is caused to execute print processing for the first surface of the second type sheet.

  The image A and the image B are subjected to layout processing using a memory that can be used for image editing processing so as to become data for one page, and then the printer unit 2 uses the second type sheet. The first side is printed.

  Further, the CPU circuit unit 122 arranges the image D in the region 2404 on the second surface (back side of the first surface) of the second type sheet, provided that the region 2403 on the second surface of the second type sheet. The printer unit 2 is caused to execute a printing process on the second surface of the second type sheet so that the image C is not arranged in the printer 2.

  As described above, in the print sequence, the printing process of the image D for the area 2404 on the second surface of the second type sheet is permitted, but the printing process of the image C for the area 2403 on the second surface of the second type sheet. Control to prohibit.

  As described above, in the fourth example, the CPU circuit unit 122 controls the printer 2 to execute print processing so that the image A and the image B are laid out on the first surface of the second type sheet. To do. Then, printing is also permitted so that the image D is laid out on the second surface of the second type sheet. However, control is performed so as to prohibit the execution of a print process in which the image C is laid out on the second surface of the second type sheet.

  A series of print processes for the second type sheet as described above are executed. Then, the second print-processed second sheet is formed on the first-type sheet bundle composed of a plurality of first-type sheets on which print data for the body (print data for a total of M pages) is printed. The sheet of the type is subjected to a gluing process by the gluing unit 300.

  As a result, a case binding print 2400 as shown in FIG. 28 can be created by the image forming system 1000.

  Next, a fifth example will be described. For example, assume that the user performs the following series of print settings on the setting screen of FIG.

  First, when the user presses the “Copy to Front Cover” key on the setting screen of FIG. 7F, the image A should be printed on the area 2401 of the second type sheet in the case binding mode. The execution instruction for the first special printing process is input.

  Further, by pressing the “copy to cover cover” key on the setting screen of FIG. 7F, the image C is printed in the area 2403 of the second type sheet in the case binding mode. The execution instruction for the second special printing process is also input.

  Further, when the user presses the “copy to back cover front” key on the setting screen of FIG. 7F, the image D is printed in the area 2404 of the second type sheet in the case binding mode. As described above, the execution instruction for the third special printing process is also input.

  However, in the case binding mode, the user does not press the “copy to back cover back” key on the setting screen of FIG. 7F and the user presses the “do not copy to back cover back” key. The execution prohibition instruction for the fourth special printing process described above is input so that the image B is not printed in the area 2402 of the second type sheet.

  In response to the series of print settings in the case binding mode as described above being executed by the user via the operation unit 123, the CPU circuit unit 122 displays a case printing bookbinding result 2400 as shown in FIG. The case binding print target job is processed by the image forming system 1000 so as to be created.

  Note that the method of referring to the print results 2400 in FIGS. 29A to 29D is the same as the method of referring to the print results 2400 in FIGS.

  That is, the CPU circuit unit 122 causes the printer unit 2 to execute the following two types of printing processes as the case binding printing process in the case binding mode in order to obtain the printing result 2400 shown in FIG.

  First, as the first print sequence in the case binding print job, the print data for the text of the case binding print target job data in the hard disk of the image memory 120 (for a total of M pages) is used as the first type sheet. On the other hand, the printer unit 2 is controlled to print.

  In addition, the CPU circuit unit 122 not only executes the first print sequence, but also uses the case binding print job as a second print sequence in association with the print data for the text of the case binding print job. Three predetermined print data stored in the memory 120, that is, the image A, the image C, and the image D are printed on the region 2401, the region 2403, and the region 2404 of the second type sheet, respectively. The printer unit 2 is controlled.

  In creating the print result 2400 shown in FIG. 29, the CPU circuit unit 122 causes the following print processing to be executed in a series of printing steps for the second type sheet.

  The state of the second type sheet before being glued to the first type sheet bundle on which the print data for the text is printed is in a state before being folded in half as shown in FIG.

  In order to obtain a printing result as shown in FIG. 29, the CPU circuit unit 122 causes the printer unit 2 to execute a printing process as shown in FIG.

  That is, the CPU circuit unit 122 arranges the image A in the area 2401 on the first surface of the second type sheet, but does not arrange the image B in the area 2402 on the first surface of the second type sheet. The printer unit 2 is caused to execute print processing for the first surface of the second type sheet.

  In addition, the CPU circuit unit 122 arranges the image C so that the image C is arranged in the region 2403 on the second surface (the back side of the first surface) of the second type sheet, and the image D is arranged in the region 2404. The printer unit 2 is caused to execute print processing for the second surface of the two types of sheets.

  The CPU circuit unit 122 executes the layout process using a memory that can be used for the image editing process so that the image C and the image D become data for one page, and then the image C and the image D are processed. The image data obtained by editing D into image data for one page is printed by the printer unit 2 on the second surface of the second type sheet.

  As described above, in the fifth example, the CPU circuit unit 122 controls the printer 2 to execute print processing so that the image C and the image D are laid out on the second surface of the second type sheet. To do. In addition, printing is also permitted so that the image A is laid out on the first surface of the second type sheet. However, control is performed so as to prohibit the execution of the printing process in which the image B is laid out on the first surface of the second type sheet.

  A series of print processes for the second type sheet as described above are executed. Then, the second print-processed second sheet is formed on the first-type sheet bundle composed of a plurality of first-type sheets on which print data for the body (print data for a total of M pages) is printed. The sheet of the type is subjected to a gluing process by the gluing unit 300.

  As a result, a case binding printed material 2400 as shown in FIG. 29 can be created by the image forming system 1000.

  In the above example, the configuration for controlling the execution of the printing process to the four areas 2401 to 2404 shown in FIG. 24 has been described. However, when the case binding is designated, the CPU circuit unit 122 moves to the back cover. The CPU circuit unit 122 controls the presence / absence of printing on the back cover (area between 2402 and 2401) based on the instruction. You may comprise.

  Since the above five examples are examples of processing a job from the reader unit 1, the printer unit 2 performs printing on the second type sheet after executing image editing using the memory of the image forming apparatus. The process was executed.

  However, for example, in the case of an external job received from an external host computer (for example, the external device 2002 in FIG. 2) via the connector 121, the second type sheet is transferred to the second type sheet via the printer driver of the host computer. The data to be printed is subjected to layout processing into one page of data, and can be transmitted from the host computer.

  Therefore, when the job to be processed is a job received from the outside in the case binding mode, the image forming system 1000 does not execute the layout processing as described above, and directly passes through the image memory 120. The printer unit 2 performs printing. As a result, even if the job to be processed in the case binding mode is a job received from the outside, the print processing as shown in FIGS. 31 to 35 can be executed, and the final print result 2400 as shown in FIGS. Can be obtained.

  As described above, in the case binding printing process in the case binding mode, as described in the five case binding printing processing examples using FIGS. 24, 25 to 29, 30, and 31 to 35, The image forming system 1000 is controlled by the CPU circuit unit 122 so that the print data for the text can be printed on the first type sheet corresponding to the sheet for the text. On the premise of this configuration, the CPU circuit unit 122 further transfers predetermined print data other than the text print data, such as print data for case binding cover, to a second type corresponding to the case binding cover sheet. The image forming system 1000 is controlled so that printing can be performed on the sheet.

  In addition, in the case where the printing process is performed on the second type sheet in the case binding mode, the two regions (2401, 4022) on the first surface of the second type sheet and the second type sheet are included. The user can determine for each area whether or not printing can be performed for each of the four areas (2403, 2404) of the second surface.

  In the above example, the configuration for determining whether or not printing can be performed for each of the four areas described above has been described. However, the following configuration may be used.

  For example, a predetermined instruction (hereinafter referred to as “permission”) that permits execution of both the first surface printing process for the second type sheet and the second surface printing process for the second type sheet. Then, this is called the first instruction) by the user.

  Further, a predetermined instruction indicating that only one of the first surface printing process for the second type sheet and the second surface printing process for the second type sheet is permitted to be executed. (Hereinafter, referred to as a second instruction) can be input by the user.

  For example, a predetermined instruction (hereinafter referred to as a third instruction) that prohibits both the first surface print processing for the second type sheet and the second surface print processing for the second type sheet. (Referred to as an instruction) can be input by the user.

  In the case binding mode, when processing the second type sheet, when the first instruction is input by the user, the CPU circuit unit 122 can create a print result 2400 as shown in FIG. Control part 2. In other words, the printer unit 2 is caused to execute print processing on both sides of the second type sheet by a printing method as shown in FIG.

  On the other hand, when processing the second type sheet in the case binding mode, if the second instruction is input by the user, the CPU circuit unit 122 can create a print result 2400 as shown in FIG. Control part 2. That is, the printer unit 2 is caused to execute print processing for only one side of the second type sheet by a printing method as shown in FIG.

  On the other hand, when processing the second type sheet in the case binding mode, if the third instruction is input by the user, the CPU circuit unit 122 prohibits the print processing itself for the second type sheet. Control to do. In this case, the printer unit 2 is controlled not to perform the printing process for the second type sheet but to be conveyed as it is from the paper discharge roller 219 of the printer unit 2 to the gluing unit 300 in the sheet processing apparatus 230. .

  In this manner, in the case binding mode, whether or not printing can be performed on the second type sheet is determined in units of paper on the second type sheet, such as the operation unit 123 (or the operation unit of the host computer if the job is received from the host computer). The user interface unit may be configured to be determined by the user.

  In the above example, in the case binding mode, a configuration is shown in which whether or not the second type sheet can be printed can be selected by the user himself / herself via the display screen of FIG. However, this embodiment may have the following configuration.

  For example, in the present embodiment, a sheet to be used as the second type sheet in the case binding mode is sent via a user interface unit such as the operation unit 123 (the operation unit of the host computer if the job is received from the host computer). Thus, it is configured so that it can be determined by the user himself.

  Under such a configuration, for example, in the case binding mode, it is assumed that the setting for the second type sheet is made by the user. In response to this, the CPU circuit unit 122 acquires information related to the sheet selected by the user as the second type sheet. Then, based on the acquired information on the second type sheet, whether to execute printing on the second type sheet in the case binding mode is automatically determined based on the judgment of the CPU circuit unit 122 itself. With such a configuration, the following situation can be dealt with.

  For example, regarding the case binding process, assuming the bookbinding product desired by the user, the following is assumed.

  For example, guidebooks and user's manuals are assumed as candidates for printed materials created by case binding. In such case-bound printed matter, it is expected that plain paper or recycled paper will be used for the text sheet. On the other hand, it is expected that a special sheet having a certain thickness, such as cardboard, is used for the case binding cover sheet for covering the text sheet.

  In addition, when things other than user needs and use cases are examined, it is considered that there are matters that should be taken into consideration regarding the configuration of the system and the device itself.

  For example, the image forming system 1000 shown in FIG. 1 has a mechanical configuration as shown in FIG. 1 for the purpose of downsizing. Due to such a mechanical configuration, double-sided printing on a sheet such as cardboard may have some influence on the system or apparatus.

  The control may be executed by the CPU circuit unit 122 with attention given to the above viewpoints. Specific examples are given below.

  For example, when a case binding process is performed on a job from the reader 1, the setting of the case binding mode can be executed by the user via the operation unit 123 as an example of the user interface unit of the present embodiment of the image forming system 1000. To. Further, for example, when performing case binding processing for a job from the host computer, the case binding mode is displayed via a print setting screen displayed on the display unit of the host computer as an example of the user interface unit of the present embodiment. Can be set by the user.

  Under such a configuration, for example, as a second type of sheet in the case binding mode, a predetermined type such as cardboard that should be prohibited from duplex printing in the printer unit 2 of the image forming system 1000 is used. It is assumed that the sheet is selected by the user via the user interface unit as described above. In this case, the printer unit 2 is controlled to prohibit the double-sided printing process from being performed on the second type sheet in the case binding mode.

  On the other hand, it is assumed that a user selects a media type sheet, such as plain paper or recycled paper, other than the predetermined type as described above, which allows double-sided printing in the printer unit 2 via the user interface unit. To do. In this case, the printer unit 2 is controlled to permit execution of the double-sided printing process on the second type sheet in the case binding mode.

  As described above, whether or not the double-sided printing process can be performed on the second type sheet of the case binding target job is directly determined by the user (via the screen as shown in FIG. 7F). Without being instructed by the CPU circuit unit 122 itself, based on information on the second type sheet to be used in the case binding mode. Such a configuration may be used.

  It is important that such control can be executed according to the circumstances of the image forming system 1000 such as the mechanical configuration as described above, but is not necessarily limited to this viewpoint. For example, a configuration may be adopted in which the control is executed as a result of considering the circumstances of the user such as preventing the user's own mistake.

  The image forming system 1000 may have the following configuration. For example, in the image forming system 1000, the sheet processing apparatus 230 shown in FIG. 1 is connected to the image forming apparatus main body. However, the sheet processing apparatus having at least the same function as the sheet processing apparatus 230 and having a special sheet feeding unit such as an inserter can be connected to the image forming apparatus main body. Yes.

  As described above, the inserter can convey a printed sheet or the like into the sheet processing apparatus 230. In addition, the sheet can be conveyed to the conveyance path inside the sheet processing apparatus 230 without going through the sheet conveyance path for passing the sheet to be imaged inside the printer unit 2.

  Therefore, when the sheet processing apparatus 230 included in the image forming system 1000 is a type of sheet processing apparatus that also includes an inserter, the case binding is performed when the user sets the case binding mode via the user interface. The inserter is configured to be selectable by the user as the second type sheet feeding source in the mode.

  For example, when case binding processing is performed for a job from the reader 1, an inserter is used as a second type sheet feeding source in the case binding mode via the operation unit 123 as an example of the user interface unit of the present embodiment. Can be selected by the user.

  Further, for example, when case binding processing is performed for a job from the host computer, the case binding mode in the case binding mode is displayed via a print setting screen displayed on the display unit of the host computer as an example of the user interface unit of the present embodiment. The inserter can be selected by the user as a feeding source for the two types of sheets.

  Under such a configuration, for example, it is assumed that the inserter is selected by the user via the user interface unit as the second type sheet feeding source in the case binding mode. In this case, when processing the case binding target job, the CPU circuit unit 122 controls the printer unit 2 to prohibit the print processing for the second type sheet.

  On the other hand, a feeding source other than the inserter (for example, any one of the paper feeding units 227, 214, 215, 225, and 226) is fed by the user via the user interface unit as a feeding source of the second type sheet. Suppose that it is selected. In this case, when processing the case binding target job, the printer unit 2 is controlled so as to permit execution of the print processing for the second type sheet.

  In this way, the user himself / herself does not directly determine whether or not to execute the print processing for the second type sheet of the case binding target job (the user directly via the screen as shown in FIG. 7F). The CPU circuit unit 122 itself may be configured to automatically determine according to the feeding source selected by the user as the feeding source of the second type sheet (without direct instruction). .

  As described above, in the case of processing a case binding target job, the image forming system 1000 according to the present embodiment performs a gluing process on a first type sheet bundle on which print data for text is printed. Whether or not to execute print processing (including double-sided printing) on the second type sheet is determined not only based on a direct instruction from the user, but also based on the judgment of the CPU circuit unit 122 itself. It is also configured so that it can be determined automatically.

  In the present embodiment, as an example of prohibiting double-sided printing on the second type sheet, a case where the printing process itself on the first surface and the second surface of the second type sheet is prohibited, and This applies to at least one of the cases where printing on either the first side or the second side of the second type sheet is permitted but printing on the other side is prohibited. It shall be.

  Further, as described above, in the present embodiment, for example, the CPU circuit unit 122 is configured to prohibit execution of double-sided printing processing on the second type sheet used as a cover of a case binding target job. .

  However, in the present embodiment, for example, when processing a case binding target job while executing such control, the second type sheet to be glued is a target body sheet (that is, the first sheet). For the type sheet), the CPU circuit unit 122 controls to permit double-sided printing.

  However, when processing a case binding target job, whether to execute double-sided printing processing or single-sided printing on the first type sheet is determined via the above-described user interface. It can be selected by the user himself.

  This control is control in consideration of user needs and use cases (use environment). For example, as described above, an output product desired by the user as a case binding printed material is assumed to be a guide book or a manual. Such printed matter may be composed of plain paper, recycled paper, or the like as a sheet for the text, and the text itself may be desired to be printed on both sides. However, the text itself is not always printed on both sides. Therefore, the above-described control may be executed in consideration of such various situations.

  With the above configuration, when an image forming apparatus and an image forming system capable of sheet gluing are put into practical use, troubles and the like occur for various needs from various users related to the sheet gluing processing mode. The above-described effect of being able to respond flexibly without any problems can be further improved.

  As described above, in the present embodiment, the CPU circuit unit 122 performs print processing for the second type sheet of the case binding target job based on the results of various determination processes related to the job to be bound. The image forming system 1000 is controlled so as to prohibit or permit execution.

  Further, the CPU circuit unit 122 performs control so as to permit only the single-sided printing to be performed on the second type sheet of the case binding target job based on the results of the various determination processes, and the double-sided printing. The execution is controlled to be prohibited.

  Further, the CPU circuit unit 122 permits only single-sided printing and prohibits double-sided printing on the first type sheet of the case binding target job based on the results of the various determination processes. Control as follows.

  In this embodiment, the results of various determination processes related to the job to be processed here are as described above for the second type sheet when the case binding mode is selected by the user. It means a determination result concerning whether or not a print execution instruction has been made by the user. Or, when the case binding mode is selected by the user, it means a result of confirmation as to what kind of media type the sheet type to be used as the second type sheet is. Alternatively, it means a determination result of whether or not the second type sheet feeding source is a predetermined feeding source such as an inserter. In this way, the CPU circuit unit 122 confirms the processing conditions of the job to be processed, and executes the various controls based on the result.

  Further, when the CPU circuit unit 122 executes the above-described controls based on the determination results, in the present embodiment, for example, these controls may be used logically or logically. , May be used.

  In this embodiment, for example, the CPU circuit unit 122 relates to the sheet gluing process by the sheet processing apparatus 230 based on whether or not the job to be processed is a job that satisfies a predetermined condition (influential). ) It is controlled to prohibit or permit execution of a predetermined process.

  As an example of the “predetermined processing”, in the present embodiment, as described above, “print processing for a sheet of a job that requires sheet gluing processing by the sheet processing apparatus 230” is described.

  However, in addition to this, in the present embodiment, for example, based on whether a job to be processed satisfies a predetermined condition or is a job, it is prohibited or permitted by the control of the CPU circuit unit 122. , “Predetermined processing” exists.

  For example, “sheet gluing processing by the sheet processing device 230” itself such as “case binding processing by the sheet processing device 230” or “sheet binding processing by the sheet processing device 230” itself is “predetermined in the present embodiment. This corresponds to a further example of “processing”.

  For example, a case where a document of a case binding job is read from the reader unit 1 is taken as an example. In this case, the CPU circuit unit 122 checks the number of pages of print data of the case binding process job based on information from a document number counter (not shown) while executing a document reading operation by the reader unit 1. Acquires the total page number information of the job.

  On the other hand, among the print processing conditions for the job set by the user, job processing conditions such as double-sided print setting, single-sided print setting, reduced layout setting, etc. that affect the number of print sheets of output paper are set. Check if it has been done.

  Based on such various determination materials, the CPU circuit unit 122 calculates the total number of sheets to be used in the job to be subjected to the case binding process.

  For example, the CPU circuit unit 122 uses the information in the management table 3600 as shown in FIG. 36 to calculate the total number of sheets required as the first type sheet in the job to be glued.

  FIG. 36 is an example of a management table that stores management information for calculating the total number of sheets necessary for a job to be processed, which is a control target in the present embodiment.

  Using the information in the table shown in FIG. 36, the CPU circuit unit 122 performs the following calculation. In FIG. 36, a variable N corresponds to the total number of sheets necessary for the job to be processed. The variable M corresponds to the total number of pages of print data of the job to be processed. The table 3600 is registered in advance as management information in the hard disk in the image memory 120, for example.

  For example, it is assumed that a single-sided printing setting is made for a series of 200 pages of print data. In this case, the CPU circuit unit 122 assigns “200” to the variable M by using the calculation formula of case 1 in the table 3600 as the total number N of output sheets necessary for the job to be processed. Thus, “N = (200 ÷ 1) ÷ 1 = 200” is calculated.

  Also, for example, assume that single-sided printing is set for a series of print data consisting of 200 pages, and the 2-in-1 mode is set as the reduced layout printing mode. The 2 in 1 mode is a print mode in which input data for two pages is printed on the same surface of one output sheet. In this case, the CPU circuit unit 122 uses the calculation formula of case 2 of the table 3600, so that the total number N of output sheets necessary for the job to be processed is “N = (200 ÷ 2) ÷. 1 = 100 ”is calculated.

  Also, for example, it is assumed that single-sided printing is set for a series of print data including 200 pages, and the 4-in-1 mode is set as the reduced layout printing mode. The “Pin 1 mode” is a print mode in which input data for “P” pages is printed on the same side of one output sheet. That is, the “4 in 1 mode” is a print mode in which input data for four pages is printed on the same side of one output sheet. In this case, the CPU circuit unit 122 uses the calculation formula of case 3 in the table 3600, so that the total number N of output sheets necessary for the job to be processed is “N = (200 ÷ 4) ÷. 1 = 50 ”is calculated.

  With such a calculation method, the case 4 and the like are similarly processed.

  In addition, for example, it is assumed that duplex printing is set for a series of 200 pages of print data. In this case, the CPU circuit 122 determines that the total number N of output sheets necessary for the job to be processed is “N (200 ÷ 1) ÷ 2 by using the calculation formula of case 5 in the table 3600. = 100 ".

  Also, for example, assume that duplex printing is set for a series of print data consisting of 200 pages, and the 2-in-1 mode is set as the reduced layout printing mode. In this case, the CPU circuit unit 122 uses the calculation formula of case 6 of the table 3600, so that the total number N of output sheets necessary for the job to be processed is “N = (200 ÷ 2) ÷. 2 = 50 ”is calculated.

  In this way, also in case 5 and subsequent cases, the total number of sheets N required for the job to be processed is calculated by substituting the total number of pages of the job to be processed into the variable M using the corresponding calculation formula. calculate.

  The CPU circuit unit 122 rounds up the value after the decimal point in the calculated value of N when the value of N becomes a value that cannot be divided as a result of calculation using the calculation formula of the table 3600. , N is calculated to be an integer value.

  The above-described confirmation process of the total number of sheets to be printed with print data necessary for the job to be processed (referred to as “number of printed sheets” in the process of the flowchart described later) is the case binding processing mode. This is executed when a gluing process mode such as a top binding process mode or the like is selected by the user. This processing step corresponds to, for example, the processing in step S9-3 in FIGS. 13, 15, and 16 described later.

  Further, the total number N of sheets corresponds to the total number of sheets of the first type that should be one output bundle in the sheet binding mode.

  On the other hand, in the case binding mode, the total number of first sheet bundles for the text may be handled. However, in the case binding mode, the final printing result is composed of a sheet bundle for the body and a cover sheet.

  Accordingly, in the case binding mode, the value of N may be a value that takes into account the case binding cover (second type sheet). That is, the total number N of sheets may be handled so as to be a value obtained by adding one sheet of the second type sheet (cover) to the total number of sheets of the first type.

  With the above configuration, the CPU circuit unit 122 performs a comparison process between the total number of sheets to be used in the case binding job and a predetermined processing number. Then, according to the comparison result, it is determined whether or not to execute the case binding process for the sheets of the case binding target job.

  In this embodiment, for example, the management information in the management table 3700 in FIG. 37 is used by the CPU circuit unit 122 when determining whether or not to execute the case binding process.

  FIG. 37 shows the restrictions related to both the total number of sheets necessary for the job to be processed and the plural types of sheet processing that can be executed by the sheet processing apparatus, which are the control targets in this embodiment. It is a figure which shows an example of the management table which memorize | stored the management information for prescription | regulation.

  The management table 3700 in FIG. 37 is registered in advance in the hard disk of the image memory 120, for example.

  The management table 3700 in FIG. 37 stores management information for providing restriction items (rules) in advance when the sheet processing apparatus 230 executes sheet processing on a sheet of a job to be processed. Yes.

  For example, in the example illustrated in FIG. 37, for each of a plurality of types of sheet processing included in the sheet processing apparatus 230, conditions for permitting execution of sheet processing on sheets of jobs to be processed, conditions for prohibiting, and the like. Is stored in the table 3700 as management information.

  With this configuration, in this embodiment, for example, the CPU circuit unit 122 calculates the total number of sheets required for the job to be processed using the information in the management table 3600 in FIG. Then, based on restriction information (rule) information regarding a plurality of types of sheet processing modes included in the sheet processing apparatus 230 as in the example of FIG. 37, the following restriction control (prohibition control) is executed.

  Note that the sheet processing apparatus 230 included in the image forming system 1000 of the present embodiment includes two types of sheet gluing processing modes, a case binding processing mode and a top gluing binding processing mode, and a saddle stitch binding processing that does not require gluing processing. Mode. Therefore, here, a description will be given specifically for these sheet processing modes.

  For example, the total number of output sheets (total number of sheets N) required for the job to be processed is less than 10 sheets (corresponding to case 1 in FIG. 37), and more than 150 sheets (FIG. 37). In this case, the CPU circuit unit 122 uses the sheet processing device 230 to perform the case binding process on the sheet of the job to be processed. It is prohibited to execute.

  Further, for example, the total number of output sheets (total number of sheets N) required for the job to be processed is 10 or more and 150 or less (in FIG. 37, 10 ≦ N ≦ 150 is expressed). (Corresponding to case 3 in FIG. 37), the CPU circuit unit 122 allows the sheet processing apparatus 230 to execute the case binding process on the sheet of the job to be processed.

  Further, for example, when the total number of output sheets (total number of sheets N) required for the job to be processed exceeds 150 (expressed as 150 <N in FIG. 37) (FIG. 37). In the case 4) of 37, the CPU circuit unit 122 prohibits the sheet processing device 230 from executing the sheet binding process on the sheet of the job to be processed.

  Further, for example, when the total number of output sheets (total number of sheets N) required for the job to be processed is 150 or less (in FIG. 37, N ≦ 150 is expressed) (in FIG. 37). (Corresponding to case 5), the CPU circuit unit 122 permits the sheet processing device 230 to execute the book binding process on the sheet of the job to be processed.

  Here, the case 5 in FIG. 37 is compared with the case 3 in FIG. If the job to be processed is a job to be bound with a top glue book, the CPU circuit unit 122 does not have a total number of sheets of the job, but the sheet top bound bookbinding process for the job. It is controlled to allow execution. As described above, in this embodiment, the CPU circuit unit 122 executes prohibition control different from the prohibition control in the case binding mode in the top binding mode. Although this reason is mentioned later, such control is also one of the characteristics.

  Further, for example, when the total number of output sheets (total number N of sheets) required for the job to be processed is more than 15 (expressed as 15 <N in FIG. 37) (FIG. 37). In the case 6), the CPU circuit unit 122 prohibits the sheet processing device 230 from executing the saddle stitch binding process on the sheet of the job to be processed.

  For example, when the total number of output sheets (total number N of sheets) required for the job to be processed is 15 or less (corresponding to case 7 in FIG. 37), the CPU circuit unit 122 The sheet processing device 230 permits the saddle stitch bookbinding process to be executed on the sheet of the job to be processed.

  Although not disclosed in FIG. 37, the sheet processing apparatus 230 has a sheet processing mode in addition to these three types of sheet processing modes. Therefore, management information similar to that in the above-described modes is written in the table 3700 for sheet processing modes other than the three types.

  As described above, in this embodiment, the restriction information (rule) information for determining whether or not the sheet processing apparatus 230 can execute the sheet processing according to the total number of sheets necessary for the job to be processed is management information. Are stored in advance in the image memory 120 of the image forming system 1000. The CPU circuit unit 122 controls whether or not to execute sheet processing on a sheet of a job to be processed while reading and referring to the restriction information from the image memory 120. Note that the CPU circuit unit 122 performs management information in the management table 3700 in FIG. 37 in the processing in step S9-5, the processing in step S9-6, and the processing in step S9-14 in the flowchart in FIG. Is used.

  By configuring as described above, problems as assumed in the prior art can be prevented in advance, and the various effects described above can be obtained with certainty.

  Further, the image forming system 1000 of the present embodiment is configured such that various types of sheets can be used as candidates for sheets to be printed. For example, the paper feed units (227, 214, 215, 225, and 226) included in the image forming system 1000 have different types (media type) such as plain paper, recycled paper, colored paper, glossy paper, and thick paper. Can be set). Then, when the user selects a desired sheet feeding unit via the user interface unit such as the operation unit 123, the user causes the user to feed a sheet of a desired media type from the desired sheet feeding unit. The image forming system 1000 is controlled by the CPU circuit unit 122 so that the printing process can be executed by the unit 2.

  Therefore, in the present embodiment, for example, the control using FIG. 37 may be developed and the following control may be executed by the CPU circuit unit 122. This will be described with reference to FIG.

  FIG. 38 shows the restrictions related to both the total number of sheets necessary for the job to be processed and the plural types of sheet processing that can be executed by the sheet processing apparatus, which are the control targets in this embodiment. It is a figure which shows an example of the management table which memorize | stored the management information for prescription | regulation.

  The information in the management table 3700 in FIG. 37 includes a plurality of types of restriction items (rules) for determining whether or not to execute sheet processing based on the number of sheets necessary for the job to be processed, which the sheet processing apparatus 230 has. Management information defined for each sheet process. The control based on the management information in FIG. 37 is a control sequence in the case where the type (media type) of the sheet to be printed is not considered in the job to be processed.

  Comparing FIG. 38 with FIG. 37, for example, the information registered in the management table 3800 in FIG. 38 is a restriction item for determining whether or not to execute sheet processing based on the number of sheets required for the job to be processed. (Rule) is management information that defines a plurality of types of sheet processing included in the sheet processing apparatus 230. That is, this point is the same as the management information in FIG.

  However, the management information in the management table 3800 shown in FIG. 38 is management information used when a control sequence is executed in consideration of the type (media type) of a sheet to be printed in a job to be processed. This table 3800 is also registered in advance as management information in the hard disk of the image memory 120 provided in this system.

  In the present embodiment, for example, the following control is executed by the CPU circuit unit 122 based on restriction information (rule) information related to sheet processing by the sheet processing apparatus 230 shown in the management table of FIG.

  It should be noted that here, as in the previous case, two types of sheet gluing processing modes, the case binding processing mode and the top gluing bookbinding processing mode, and the saddle stitch binding processing mode that does not require gluing processing will be described. As in the previous embodiment, in this embodiment, for example, the CPU circuit unit 122 acquires information on the total number N of sheets necessary for the job to be processed by using the information in the management table 3600 in FIG. In addition, control based on the management information of FIG. 38 is executed.

  For example, in the job to be processed, the sheet type (media type) to be printed is assumed to be plain paper or recycled paper.

  Here, such a job that uses a media type sheet such as plain paper or recycled paper is referred to as a first media type job.

  As described above, when the job to be processed is a job of the first media type, the total number of output sheets (total number of sheets N) necessary for the job to be processed is less than 10 ( When the case 1 corresponds to case 1 in FIG. 38) and more than 150 sheets (represented as 150 <N in FIG. 38) (when it corresponds to case 2 in FIG. 38), the CPU The circuit unit 122 prohibits the sheet processing apparatus 230 from executing the case binding process on the sheet of the first media type job to be processed.

  Also, for example, when the job to be processed is a job of the first media type, the total number of output sheets necessary for the job to be processed (total number N of sheets) is 10 or more and 150 sheets. In the following case (represented as 10 ≦ N ≦ 150 in FIG. 38) (when the case 3 corresponds to case 3 in FIG. 38), the CPU circuit unit 122 causes the job of the first media type to be processed. The sheet processing device 230 permits the case binding process to be executed on the sheet.

  For example, when the job to be processed is a job of the first media type, the total number of output sheets (total number of sheets N) required for the job to be processed exceeds 150 (see FIG. 38, it is expressed as 150 <N) (corresponding to case 4 in FIG. 38), the CPU circuit unit 122 determines the sheet for the job of the first media type job to be processed. The processing device 230 prohibits execution of the top glue binding process.

  Further, for example, when the job to be processed is a job of the first media type, the total number of output sheets necessary for the job to be processed (total number N of sheets) is 150 sheets or less (in FIG. 38). , N ≦ 150) (corresponding to case 5 in FIG. 37), the CPU circuit unit 122 applies the sheet processing apparatus to the sheet of the first media type job to be processed. By 230, it is permitted to execute the sheet binding process.

  Further, for example, when the job to be processed is a job of the first media type, the total number of output sheets (total number N of sheets) necessary for the job to be processed exceeds 15 (see FIG. 37, it is expressed as 15 <N) (Case 6 in FIG. 38), the CPU circuit unit 122 applies the sheet processing device to the job sheet of the first media type to be processed. 230 prohibits the saddle stitch bookbinding process from being executed.

  For example, when the job to be processed is a job of the first media type, the total number of output sheets (total number N of sheets) required for the job to be processed is 15 or less ( 38), the CPU circuit unit 122 permits the sheet processing device 230 to execute the saddle stitch binding process on the sheet of the first media type job to be processed. .

  Next, it is assumed that in the job to be processed, the sheet type (media type) to be printed is a media type such as colored paper or glossy paper.

  Here, a job that uses a sheet of a media type that is different from the above-described media type sheet, such as colored paper or glossy paper, is referred to as a second media type job.

  In the present embodiment, for example, the second media type sheet has the same sheet size as the first media type sheet, but has a different sheet thickness. A sheet is included. For example, a sheet having a thickness greater than that of the first media type sheet is included in the second media type sheet.

  Thus, when the job to be processed is a job of the second media type, the total number of output sheets (total number N of sheets) required for the job to be processed is less than 8 (in FIG. 38, , N <8) (in the case corresponding to case 8 in FIG. 38) and more than 100 sheets (in FIG. 38, expressed as 100 <N) ( 38), the CPU circuit unit 122 prohibits the sheet processing apparatus 230 from executing the case binding process on the second media type job sheet to be processed. To do.

  For example, when the job to be processed is a job of the second media type, the total number of output sheets necessary for the job to be processed (total number N of sheets) is 8 or more and 100 sheets. In the case of the following (represented as 8 ≦ N ≦ 100 in FIG. 38) (when the case 10 corresponds to case 10 in FIG. 38), the CPU circuit unit 122 causes the job of the second media type to be processed. The sheet processing device 230 permits the case binding process to be executed on the sheet.

  For example, when the job to be processed is a job of the second media type, the total number of output sheets (total number of sheets N) required for the job to be processed exceeds 100 (see FIG. 38 is expressed as 100 <N) (corresponding to the case 11 in FIG. 38), the CPU circuit unit 122 determines that the sheet of the second media type job to be processed is the sheet The processing device 230 prohibits execution of the top glue binding process.

  For example, when the job to be processed is a job of the second media type, the total number of output sheets (total number of sheets N) required for the job to be processed is 100 or less (total number of sheets) ( 38), the CPU circuit unit 122 permits the sheet processing device 230 to execute a binding binding process on the sheet of the second media type job to be processed. .

  For example, when the job to be processed is a job of the second media type, the total number of output sheets (total number N of sheets) necessary for the job to be processed exceeds 10 (see FIG. 38, 10 <N) (case 13 in FIG. 38), the CPU circuit unit 122 applies the sheet processing apparatus to the sheet of the second media type job to be processed. 230 prohibits the saddle stitch bookbinding process from being executed.

  Also, for example, when the job to be processed is a job of the second media type, the total number of output sheets necessary for the job to be processed (total number of sheets N) is 10 or less ( 38), the CPU circuit unit 122 permits the sheet processing device 230 to execute the saddle stitch binding process on the second media type job sheet to be processed. .

  Next, it is assumed that the type (media type) of a sheet to be printed in a job to be processed is a media type such as cardboard.

  Here, a job that uses a sheet of a media type that is different from the above-described first and second media type sheets, such as cardboard, is referred to as a third media type job.

  In the present embodiment, for example, the sheet of the third media type has the same sheet size as that of the first and second media types, but the number of sheets per sheet is the same. Sheets of different thickness are included. Further, for example, a sheet having a thickness greater than that of the first and second media types is included in the third media type.

  As described above, when the job to be processed is a job of the third media type, the total number of output sheets (total number of sheets N) required for the job to be processed is less than 5 ( In the case of the case 15 in FIG. 38), and in the case where the number exceeds 75 (represented as 75 <N in FIG. 38) (in the case of the case 16 in FIG. 38), the CPU The circuit unit 122 prohibits the sheet processing apparatus 230 from executing the case binding process on the third media type job sheet to be processed.

  Further, for example, when the job to be processed is a job of the third media type, the total number of output sheets necessary for the job to be processed (total number N of sheets) is 5 or more and 75 sheets. In the following cases (when the case 17 corresponds to case 17 in FIG. 38), the CPU circuit unit 122 performs the case binding process on the sheet of the third media type job to be processed by the sheet processing apparatus 230. Allow to execute.

  Further, for example, when the job to be processed is a job of the third media type, the total number of output sheets (total number N of sheets) required for the job to be processed exceeds 75 (see FIG. 38 is expressed as 75 <N) (corresponding to the case 18 in FIG. 38), the CPU circuit unit 122 determines the sheet for the third media type job to be processed. The processing device 230 prohibits execution of the top glue binding process.

  Further, for example, when the job to be processed is a job of the third media type, the total number of output sheets necessary for the job to be processed (total number N of sheets) is 75 sheets or less ( 38), the CPU circuit unit 122 permits the sheet processing device 230 to execute the binding binding process on the sheet of the third media type job to be processed. .

  For example, when the job to be processed is a job of the third media type, the total number of output sheets necessary for the job to be processed (total number of sheets N) exceeds 5 (see FIG. 38, it is expressed as 5 <N) (Case 20 in FIG. 38), the CPU circuit unit 122 performs sheet processing on the sheet of the third media type job to be processed. 230 prohibits the saddle stitch bookbinding process from being executed.

  Also, for example, when the job to be processed is a job of the third media type, the total number of output sheets necessary for the job to be processed (the total number N of sheets) is 5 or less ( 38), the CPU circuit unit 122 permits the sheet processing device 230 to execute the saddle stitch binding process on the sheet of the third media type job to be processed. .

  Although not disclosed in FIG. 38, the image forming system 1000 can be set in the paper feeding unit in addition to these media type sheets and can be printed by the printer unit 2. Accordingly, similar management information is written in the table 3800 for sheets of other media types.

  As described above, according to the present embodiment, in consideration of the media type (type) of the sheet to be printed by the printer unit 2 in the job to be processed, according to the total number of sheets required in the job to be processed. Restriction item (rule) information for determining whether or not to execute sheet processing by the sheet processing apparatus 230 is stored in advance in the image memory 120 of the image forming system 1000 as management information.

  Then, the CPU circuit unit 122 reads out the restriction information from the image memory 120 and refers to whether or not the sheet processing can be performed on the sheet of the processing target job, considering the media type of the sheet used in the processing target job. And is configured to control. The CPU circuit unit 122 performs management information in the management table 3800 in FIG. 38 in the processing in step S10-1, the processing in step S9-5, and the processing in step S9-6, which will be described later. Is used.

  Here, the case 5 in FIG. 38 and the case 3 in FIG. 38 will be compared. In the case where the job to be processed is a first media type job to be bound by the glue binding, the CPU circuit unit 122 has a total number of sheets of the first media type job to be processed of less than 10 sheets. Even if there is, control is performed so as to permit execution of the sheet top binding process for the job of the first media type.

  Also, compare the case 12 of FIG. 38 with the case 10 of FIG. In the case where the job to be processed is a second media type job that is the target of book binding, the CPU circuit unit 122, even if the total number of sheets of the second media type job to be processed is less than eight. Even if there is, control is performed so as to permit execution of the sheet top binding process for the second media type job.

  Also, compare the case 19 in FIG. 38 with the case 17 in FIG. In the case where the job to be processed is a third media type job that is the target of book binding, the CPU circuit unit 122, even if the total number of sheets of the third media type job to be processed is less than five. Even if there is, control is performed so as to permit execution of the sheet top binding process for the third media type job.

  As described above, in this embodiment, even when considering the media type of the job to be processed, the CPU circuit unit 122 performs the prohibition control different from the prohibition control in the case binding mode in the top binding mode. Running. This is also an example of the feature of this embodiment.

  By configuring as described above, for example, when performing prohibition control related to sheet gluing processing in the image forming system 1000, it is possible to realize finer control that also considers the media type. The effect of form can be further improved.

  Next, operations of the printer unit 2 and the sheet processing apparatus 230 when executing the case binding process will be described.

  In the present embodiment, for example, it is assumed that the CPU circuit unit 122 permits the case binding process to be executed on a sheet of a job to be processed based on the determination based on the various rules as described above.

  In this case, the image data for text in the series of print data of the job to be processed received from the reader unit 1 or the external device 2002 and stored in the hard disk of the image memory 120 is converted by the printer unit 2. The body sheets (corresponding to the first type sheet) in the case binding process are sequentially printed.

  The first type sheets that have been printed by the printer unit 2 are transported to the processing tray of the gluing unit 300 of the sheet processing apparatus 230, and sequentially on the tray until the gluing process described later is completed. Control stacking in page order.

  Assume that the print processing of all pages of the print data for the text to be printed on the first type sheet is completed, and all the first type sheets for the text are stacked on the tray of the gluing unit 300.

  In response to this, the CPU circuit unit 122 includes the sheet processing device 230 for a portion corresponding to a spine portion of a sheet bundle (corresponding to a first type sheet) on which image data for text is printed. The pasting unit 300 executes the pasting process.

  At this time, the CPU circuit unit 122 transfers a case binding cover sheet (second type) in the job from a predetermined sheet feeding unit (for example, the manual sheet feeding unit 227) selected by the user of the job. (Corresponding to the sheet) is controlled to be fed.

  After that, the back cover part of the first type sheet bundle in which the pasting process has been performed on the back cover part and the image data for text has been printed, and the center part of the cover sheet of the case binding process (for example, FIG. 30 to 35), the cover sheet (corresponding to the second type sheet) is pressed against the body sheet bundle (a series of first type sheet bundles) in the gluing unit 300 so that they match. Thus, the gluing process is executed.

  Then, after the adhesion of the cover sheet and the text sheet is completed in the spine portion, the cover sheet is folded so that the text sheet is wrapped around the spine portion. Then, the sheet roller of the job for which case binding processing has been completed is controlled to be discharged onto the stacking tray of the sheet processing apparatus 230 by the discharge roller.

  As a result, a final printing result can be obtained in which the case binding process has been executed as shown in the example at the right end of FIG. 8A and as shown in FIGS.

  In this embodiment, as shown in FIG. 8A and FIGS. 25 to 29, in case binding processing, a cover (corresponding to the second type sheet in case binding mode) is used as a sheet bundle of medium sheets (text). Note that a series of sheet bundles, ie, a series of sheet bundles of the first type, need to be firmly adhered (glued).

  In the present embodiment, in order to realize such an operation, a certain amount of thickness is necessary with respect to the thickness of the sheet bundle of the middle sheets so that the case binding cover and the gluing process can be properly executed. Focus on things.

  In other words, this embodiment focuses on the fact that the following problem may occur if the thickness of the first type sheet bundle is very small. Yes.

  For example, in case binding, the thickness of a sheet bundle of middle sheets (referred to as a first type sheet bundle in the present embodiment) means a spine portion of the first type sheet bundle. A portion corresponding to the spine portion is an area (see FIG. 30 and the like) where the second type sheet and the first type sheet bundle should be glued.

  Further, the larger the total number of first type sheets to be used in one job (that is, the value of N described in FIG. 36, FIG. 37, and FIG. 38) is, the more the first type. The thickness of the sheet bundle increases. Conversely, the smaller the total number of sheets of the first type sheets to be used in one job (that is, the value of N described in FIG. 36, FIG. 37, and FIG. 38) is, the smaller the first. The thickness of the type sheet bundle is reduced.

  That is, if the thickness of the first type sheet bundle is too small, that is, if the area of the spine cover portion is too small, the area where the second type sheet and the first type sheet bundle should be glued, It means very little. And the smaller the area to be glued between the first type sheet bundle and the second type sheet, the lower the adhesion rate of these sheets. And, the fact that the adhesion rate of these sheets is reduced, that is, even if the second type sheet is glued to the first type sheet bundle, the second type sheet is removed from the first type sheet bundle, The possibility of peeling off may occur.

  Even if such a problem does not occur, the following problem may occur.

  For example, in the case binding, in order to obtain the final product as shown in the right example of FIG. 8A and FIGS. 25 to 29, the first type sheet is used in the gluing unit 300 of the sheet processing apparatus 230. After the bundle and the second type sheet bundle are glued, the sheet processing apparatus 230 needs to execute a process of folding the second type sheet so as to cover the first type sheeter bundle.

  As described above, when folding the sheet bundle in the case binding format, if the number of the first type sheets is too small (that is, the thickness of the first sheet bundle is small), the first sheet corresponding to the cover is used. “Wrinkles” and “breakage” may occur in the two types of sheets.

  There may be some problems other than these problems. In any case, the present embodiment focuses on the fact that the output result desired by the user may not be obtained if the total number of first type sheets is too small in the case binding mode. is doing.

  Therefore, in order to prevent the occurrence of various problems as described above, in the present embodiment, for example, the control described in Case 1 shown in FIG. 37, Case 1, Case 8, and Case 15 shown in FIG. Is provided.

  That is, as one of the conditions for permitting execution of the case binding process, a minimum line relating to the total number of sheets required for the job to be processed is set in advance. In the present embodiment, for example, in the sheet gluing mode, this minimum line is set to “minimum allowable number”, “minimum number”, “first threshold value”, “lower limit value”, or “first value”. It is referred to as “a predetermined number of 2”. For example, in the example of FIG. 37, a value corresponding to “10 sheets” corresponds to the first threshold value.

  As in the example of FIG. 38, when considering the media type of the sheet to be printed by the printer unit 2, the first threshold value is set for each media type that can be used in the image forming system 1000. , Respectively.

  For example, referring to the example of FIG. 38, when processing a job of the first media type, a value corresponding to “10 sheets” corresponds to the first threshold value. In the case of processing a job of the second media type, a value corresponding to “8 sheets” corresponds to the first threshold value. When processing a job of the third media type, a value corresponding to “5 sheets” corresponds to the first threshold value.

  As described above, in the present embodiment, for example, the CPU circuit unit 122 executes the determination based on the first threshold value for the case binding target job. However, the CPU circuit unit 122 does not execute the determination based on the first threshold value for the job to be bound with the glue. This is because in the top glue binding mode, the second type sheet is not glued to the first type sheet bundle. That is, the problem assumed in case binding cannot occur. This is also one of the features of this embodiment.

  In the present embodiment, for example, when the CPU circuit unit 122 makes a determination for a job for which the case binding mode is selected and for a job for which the top binding mode is selected, Judgment based on the threshold is performed.

  This second threshold is also one of the conditions for permitting the execution of the case binding process, and is also one of the conditions for permitting the execution of the top binding process. If the value corresponding to the total number of all sheets required for the job to be processed exceeds the second threshold, the case binding mode is prohibited and the top binding mode is set. It is also prohibited to execute

  In the present embodiment, for example, the second threshold is set to “maximum allowable number of sheets”, “maximum number of sheets”, “upper limit value”, or “first predetermined number of sheets” in the gluing processing mode. I call it. For example, in the example of FIG. 37, a value corresponding to “150 sheets” corresponds to the second threshold value.

  As in the example of FIG. 38, when considering the media type of the sheet to be printed by the printer unit 2, the second threshold value is set for each media type that can be used in the image forming system 1000. Each is set in advance.

  For example, referring to the example of FIG. 38, when processing a job of the first media type, a value corresponding to “150 sheets” corresponds to the second threshold value. When processing a job of the second media type, a value corresponding to “100 sheets” corresponds to the second threshold value. When processing a job of the third media type, a value corresponding to “75 sheets” corresponds to the second threshold value.

  The reason why the control based on the second threshold value is executed is because, for example, the mechanical configuration of the image forming system 1000 is taken into consideration. This is because, for example, the processing capability of the sheet processing apparatus 230 is taken into consideration.

  In the present embodiment, for example, even if the media type is not considered as shown in FIG. 37 described above, or the media type as shown in FIG. ”And“ second threshold ”may be configured to be changeable by the user manually or automatically without user instruction under the control of the CPU circuit unit 122.

  For example, these “first threshold (second predetermined number)” and “second threshold (first predetermined number)” depend on the processing capability of the image forming system, particularly the sheet processing apparatus 230. To do. On the other hand, the sheet processing apparatus 230 is configured to be detachable from the image forming apparatus body as an option.

  Accordingly, considering the possibility that a sheet processing apparatus having a processing capability different from that of the sheet processing apparatus 230 is connected to the image forming apparatus main body, for example, the above values are displayed on the display unit 4-250 of the operation unit 123. It may be configured such that it can be arbitrarily changed by a specific user such as an administrator via an administrator setting screen (not shown).

  Alternatively, when the state is changed from the state where the sheet processing apparatus is not connected to the image forming apparatus main body to the state where the sheet processing apparatus is connected to the image forming apparatus, the equipment information of the connected sheet processing apparatus is displayed as the sheet processing apparatus. CPU circuit part 122 acquires from the side. Then, based on the acquired processing capability information of the sheet processing apparatus, the CPU circuit unit 122 itself automatically changes the threshold value so that the setting value is suitable for the sheet processing apparatus based on its own determination. Also good.

  Of the two types of threshold values, the “first threshold value” can be said to be a static determination element based on user merit, such as the quality of a print result, rather than a dynamic determination element for each apparatus.

  Therefore, even if the threshold value can be set and changed manually by the user or automatically by the CPU circuit unit 122, only the “second threshold value” can be changed. The configuration may be such that the setting change of the “first threshold value” is prohibited so that the “threshold value” becomes a fixed value.

  As described above, in the present exemplary embodiment, the pasting process can be executed only on the sheet printed by the image forming system 1000. Considering the convenience of the device itself, user needs, use environment of this system, use case, etc., various ideas relating to sheet gluing processing have been devised. For example, in order to obtain such an effect, the image forming system 1000 can also execute the following control.

  The image forming system 1000 according to the present embodiment also performs control related to sheets (first type sheet and second type sheet) themselves to be used in a case binding process job when performing the case binding process. This is executed by the CPU circuit unit 122.

  For example, in the case binding mode, a sheet (corresponding to a first type sheet) selected by the user as a body sheet is an A4 size sheet (the length in the sheet conveyance direction is 210 mm, and is perpendicular to the sheet conveyance direction). It is assumed that the sheet has a length in the direction of 297 mm.

  In this case, the case binding cover sheet for wrapping the A4 size text sheet bundle is, for example, an “A3 spread” size sheet (the length in the sheet conveying direction is 483 mm, and is perpendicular to the sheet conveying direction). A sheet having a length of 329 mm) is preferable. Thus, a sheet having a size larger than at least a sheet of A3 size (the length in the sheet conveyance direction is 420 mm and the length in the direction perpendicular to the sheet conveyance direction is 297 mm) is preferable.

  If not, for example, the length in the direction perpendicular to the sheet conveyance direction is 297 mm, and the length in the sheet conveyance direction is [(210 mm × 2) + the thickness of the sheet bundle for the text. It is preferable to select a sheet having at least a length corresponding to (that is, a thickness per sheet for the text × corresponding to the total number of sheet bundles for the text)] mm. .

  This is due to circumstances specific to case binding. Based on this point of view, the CPU circuit unit 122 should use the cover sheet (second type sheet) in the job to be processed when using the cover sheet (second type sheet) in the case binding mode. In addition to considering the size information of the body sheet (corresponding to the first type sheet) itself (in the above example, A4 size = 210 mm × 297 mm), the body sheet bundle for the job (first type sheet) The present system controls the back cover portion of the sheet bundle (corresponding to a sheet bundle), that is, the thickness information of the text so that a sheet having a size that is considered is selected.

  With this configuration, it is possible to prevent inconveniences such as the body sheet protruding from the cover sheet when the body output bundle is wrapped with the cover sheet. As shown in FIG. 8A, it is possible to create an output product in which the sheet bundle for the text is properly covered with the cover sheet.

  Here, if the case binding process is executed, the CPU circuit unit 122 controls the sheet processing apparatus 230 to execute the following process even if the cover and the text do not match in size, and the case is thereby controlled. It is possible to prevent improper output from being created during bookbinding.

  For example, a cover sheet (corresponding to a second type sheet) is glued to a text sheet bundle (corresponding to a first type sheet bundle), the cover sheet is folded, and the folded sheet is then processed. Control is performed so that the three-side cutting process is performed on the bundle by the trimmer unit 247 or the like included in the sheet processing apparatus 230.

  The above-mentioned three-way trimming process means that three of the four end portions (upper end portion, right end portion, left end portion, lower end portion) of the sheet other than the end portion corresponding to the spine cover portion at the time of case binding. These are operations for cutting out a predetermined length.

  For example, an output result example after case binding shown in the right end of FIG. 8A will be described from the upright state. Or it demonstrates using FIG. 24 (a), FIG. 25 (a), etc. FIG.

  The end portion corresponding to the spine portion of the case binding printed material shown in these is the left end portion. The three end portions other than the end portions are an upper end portion, a right end portion, and a lower end portion. These three ends are each cut by a predetermined width. Such a process of cutting the three end portions other than the spine portion by a predetermined length from the end portion is referred to as a three-side cutting process.

  The CPU circuit unit 122 executes such a three-way cutting process on the sheet bundle after the sheet folding process as described above is completed in response to the setting of the processing conditions related to the cutting process from the user. The trimmer unit 247 is controlled so as to do this.

  It should be noted that the cutting process may be controlled to be automatically executed in response to the case binding mode being selected by the user without the user explicitly inputting a cutting process execution instruction. .

  The above processing is executed in the case binding process target job. As a result, even if the cover sheet and the body sheet are mismatched, it is possible to obtain a beautiful output result in which the edge of the sheet is prepared as the case binding output result.

  Next, the “top glue bookbinding process”, which corresponds to a different kind of glue bookbinding process from the case bookbinding process that can be executed by the image forming system 1000 according to the present embodiment, will be described.

  An example of an execution procedure of the top glue binding process will be described. In this case as well, the data generation of the job to be processed is the reader unit 1 of the own apparatus, the original set on the reader unit 1 is printed, and the sheet processing apparatus is applied to the sheet printed by the print process. A series of processing procedures in the case of performing the sheet binding process by 230 will be described.

  First, the “bookbinding mode” is selected by the user via the screen key 801 of FIG. 6A displayed on the display unit 4-250 of the operation unit 123, and the key 803 of the screen of FIG. If the user inputs an instruction to “glue and bind” and “cover setting” is not made by the user via the screen shown in FIG. 7F described later (on the sheet on which the body image data is printed). When the user has not instructed the setting to attach a cover), the CPU circuit unit 122 determines that the job to be processed according to the user setting is a “job to execute the book binding process”. To do.

  When the user sets the various print processing conditions for the job to be processed and the start key 4-242 of the operation unit 123 in FIG. 4 is pressed by the user, the CPU circuit unit 122 displays the reader unit. Document bundles placed by the user on one document feeder 101 are fed one by one from the top page one by one to the reading position on the platen glass of the reader unit 1 to perform document reading processing for the job. It is executed by the reader unit 1. Then, the CPU circuit unit 122 controls the memory 120 and the like so that these read data are stored in the hard disk or the like of the image memory 120 as needed as text data (contents) in the gluing bookbinding process.

  The result of printing the stored data corresponds to, for example, “double-side printing for text” in FIG.

  However, although the output result for the text is “double-sided printing” in FIG. 8B, it is not always necessary to execute double-sided printing on the sheet on which the text image is printed in the top glue binding process. . Therefore, for example, also in the book binding process, the user can select and decide whether to perform single-sided printing or double-sided printing on the sheet on which the image for the text is printed via the key 4-258 on the screen in FIG. You may comprise.

  As described above, in the case binding mode, the execution of the double-sided printing process on the second type sheet is prohibited in some cases. However, even when the case binding mode is selected and the execution of double-sided printing on the second type sheet is prohibited, the sheet of the job to be processed in the top glue binding mode is displayed. On the other hand, it is controlled to permit execution of double-sided printing. Then, in accordance with an instruction from the user, control is performed so that the double-sided printing process can be executed on the sheet of the job to be processed in the sheet binding mode.

  The CPU circuit unit 122 counts the number of pages of data of the job to be processed by the book binding process based on information from the document number counter while executing the document reading operation by the reader unit 1. Job processing that affects the number of pages to be printed, such as double-sided printing settings, single-sided printing settings, and reduced layout settings, among the total page number information of the job and the print processing conditions for the job set by the user The conditions are checked, and the total number of sheets to be used in the job is calculated based on such various determination materials (this process is performed in, for example, step S9- in FIG. 13, FIG. 15, or FIG. 16 described later). 3).

  Note that the CPU circuit unit 122 calculates the total number N of sheets in the present embodiment, for example, the process equivalent to the process described with reference to FIG. I do.

  Then, the CPU circuit unit 122 performs a comparison process between the total number of sheets to be used in the sheet binding processing target job and a predetermined processing number, and the processing target job satisfies a predetermined condition. Judge whether to meet or not.

  For example, when it is determined that the job satisfies a predetermined condition, the CPU circuit unit 122 performs control so as to permit the execution of the sheet binding process for the sheet of the job. On the other hand, when it is determined that the job to be processed with the top-sheet binding process is a job that does not satisfy a predetermined condition, control is performed to prohibit the execution of the top-sheet binding process with respect to the sheet of the job.

  As an example of the case where such control for determining whether or not to execute the binding method is performed, in this embodiment, for example, if the sheet media type used in the job to be processed is not considered, the CPU The circuit unit 122 executes the control described in Case 4 and Case 5 of FIG.

  In addition, as an example of performing control for determining whether or not to execute the top binding mode, in this embodiment, for example, if the sheet media type used in the job to be processed is considered, the CPU The circuit unit 122 executes the control described in case 4 and case 5 in FIG. 38, case 11 and case 12 in FIG. 38, and case 18 and case 19 in FIG.

  If the execution of the book binding process is permitted, the printer unit 2 causes the image data for the text of the job to be processed stored in the hard disk of the image memory 120 to be printed. The gluing unit 300 included in the sheet processing device 230 causes the gluing process to be executed on the portion corresponding to the spine portion of the sheet bundle on which the image data for the text is printed.

  After that, unlike the case binding process, the back cover part is glued without feeding the cover, gluing the cover sheet to the body sheet, or wrapping it. The sheet bundle on which the text image has been printed is controlled to be discharged onto the stacking tray of the sheet processing apparatus 230 as a sheet bundle of the job for which the sheet binding process has been completed by the discharge roller.

  As a result, a final printing result that has been subjected to the sheet binding process as in the example at the right end of FIG. 8B is obtained.

  As shown in FIG. 8B, it is not necessary to attach a cover in the case binding. In other words, in the sheet binding process, there is no need for the operation of bringing the cover into close contact with the sheet bundle of the middle sheets. Therefore, there is no problem even if the sheet bundle of middle sheets is not thick.

  In other words, for example, in the case binding mode, the “second type sheet may be peeled off from the first type sheet bundle”, which may occur due to the small thickness of the middle sheet bundle, “cover” In addition, the problem that wrinkles and breakage may occur does not occur in the top binding process. The present embodiment also pays attention to these points.

  Based on this viewpoint, under the control of the CPU circuit unit 122, independent job control as described above, which is different from the job control during the case binding process, is performed during the top binding process.

  For example, in the case binding mode, as described above, the “first threshold value” is set in advance regardless of whether or not the media type of the sheet to be printed by the printer unit 2 is considered in the job to be processed. is doing. If the total number N of sheets necessary for the job to be processed is less than the first threshold value, the case binding process is prohibited.

  However, in the present embodiment, when executing the sheet binding process, the CPU circuit unit 122 executes such control that is not based on the “first threshold”.

  In other words, even if the total number of sheets necessary for the job to be bound with the top glue book falls below, for example, the first threshold value, control is performed so as to permit the execution of the top glue process.

  With respect to this point, the comparison between Case 5 and Case 3 in FIG. 37, the comparison between Case 5 and Case 3 in FIG. 38, the comparison between Case 12 and Case 10 in FIG. 38, and the case 19 in FIG. As described in the comparative explanation with case 17.

  Thus, this embodiment assumes all situations, for example. A digital image forming apparatus capable of printing print data of various jobs input from a scanner or a network via a large-capacity memory such as a hard disk, and for a sheet conveyed from the image forming apparatus In view of the practical application of an image forming system such as a digital printing system equipped with a sheet processing apparatus capable of performing at least sheet pasting processing, various ideas have been devised.

  As a result, for example, even if such devices and systems are actually put into practical use, various users who wish to perform sheet gluing processing in a digital printing environment without causing problems as previously assumed. Can provide a user-friendly and convenient system that flexibly responds to various needs.

  In all of the present embodiments including the first to third embodiments, various controls related to the sheet gluing process are executed, and thereby various effects including the above-described effects can be achieved. It is like that.

  However, the present invention is not limited to only performing all these controls. Because, if it becomes possible to execute control related to at least one sheet gluing process among various controls of the present embodiment, it will be superior to the apparatus and system assumed in the prior art, Usability is improved and effects can be obtained. Therefore, any control that can execute at least one of the controls related to various sheet gluing processes described in the present embodiment falls under the present invention.

  In this embodiment, as described above, when the sheet gluing process is executed, the sheet itself to be used in the job to be processed is also controlled. This point will be described with reference to FIG. 6, FIG. 7, and FIG.

  For example, when the user presses the glue binding key 803 on the setting screen in FIG. 6C and presses the “OK” key, the CPU circuit unit 122 detects the user operation and detects the user operation. -250 displays the paper selection screen (paper selection screen for the body sheet in the gluing processing mode) shown in FIG.

  When the key 803 is pressed on the screen of FIG. 6C, the glue binding process is performed as a sheet process (also referred to as post-processing or finishing process) for a sheet printed by the image forming apparatus. It is assumed that the processing condition for the target job is set by the user.

  As described above, when the job to be processed is a job to be subjected to the gluing bookbinding process, the CPU circuit unit 122 determines that the body sheet (the image on which the text image is formed) This corresponds to one type of sheet), and is controlled so as to limit sheet candidates that are allowed to be selected by the user.

  For example, there are a total of N types of sheet candidates that can be imaged by the image forming apparatus of the present embodiment, and there are a total of N types of sheet processing candidates that can be executed by the sheet processing apparatus (bookbinding apparatus) 230. .

  In this case, the CPU circuit unit 122 creates and stores a management table 1800 as shown in FIG. 18 in advance in the hard disk inside the image memory 120 of the image forming apparatus of this embodiment.

  FIG. 18 shows management information for specifying restrictions related to both a selection candidate of a plurality of types of sheets that can be printed by the printer unit of this embodiment and a plurality of types of sheet processing that can be executed by the sheet processing apparatus. It is a figure which shows an example of the management table which memorize | stored.

  In the management table 1800, the restriction items (rules) for restricting the sheet candidates permitted to be used in the job to be processed to a plurality of types of sheets included in the sheet processing apparatus 230 are management information. , Remembered. The restriction item information defined in the management table 1800 is stored in the hard disk of the image memory 120 included in the image forming system 1000, similarly to the management table 3700 in FIG. 37 and the management table 3800 in FIG.

  Based on the management information in the management table 1800, the CPU circuit unit 122 can execute sheet candidates that can be selected by the user in the job to be processed by the sheet processing apparatus (bookbinding apparatus) 230 included in the system. Each sheet process of a plurality of sheet processes is managed separately.

  Under such a configuration, the CPU circuit unit 122 performs the following control based on the management information in the management table 1800 in FIG. Here, as an example, a case binding process and a sheet binding process will be specifically described among a plurality of types of sheet processes that can be executed by the sheet processing apparatus 230.

  For example, it is assumed that the case binding processing mode corresponding to one of the gluing bookbinding processing is selected by the user as the processing condition for the job to be processed.

  In this case, for example, based on the rules defined in the management table 1800, the CPU circuit unit 122 selects a sheet that is allowed to be selected by the user as a body sheet in the case binding processing target job “A4, LTR (letter ), A5R, STMT-R, B5 ”(in the table of FIG. 18, both the case binding mode and the top binding mode are marked with a circle indicating that use is permitted as a text sheet. 5 paper selection candidates).

  In this embodiment, the display unit of the operation unit is configured so that the user can select a desired sheet as a body sheet (first type sheet) in the case binding process from the selection target candidates. Display control for 4-250 is executed.

  Further, the CPU circuit unit 122, based on the information in the management table 1800, “A5, A3, LGL (Legal), 11 × 17 (Leisure), A4R, LTR-R (Letter R), B4, A3 Nobi”, etc. The case binding process for candidates (eight paper selection candidates with a cross mark indicating that use as a text sheet is prohibited in both the case binding mode and the top binding mode in the table of FIG. 18). The sheet for the body (first type sheet) is not selected. Then, control is performed to prohibit the printing of the body image data of the case binding target job for the sheet corresponding to the selection-prohibited target paper candidate.

  In the present embodiment, in order to prevent an erroneous operation by the user, it is prohibited for the user to select these selection-prohibited target paper candidates as body sheets in the case binding processing mode. For example, display control on the display unit of the operation unit 123 is performed so that these selection-prohibited sheets cannot be selected by the user.

  For example, the CPU circuit unit 122 controls the display unit 4-250 to display an operation screen as shown in FIG. 7D based on the management information in the management table 1800 in FIG.

  In the display screen of FIG. 7D, the recording paper size that can be selected as the intermediate paper (text) corresponding to the sheet on which the image data for the text is printed in the glue binding process mode is “A4 Nobi, A4, B5, A5R, The guidance display is executed so as to notify the user that “LTR, STMT-R”.

  In addition, the CPU circuit unit 122 selects a selection candidate (in this example) that is permitted to be used as a body sheet (first type) when executing the gluing processing mode via the screen of FIG. Based on the management table 1800 of FIG. 18, the operation unit 123 is controlled so that the user can select a desired sheet from at least five candidates).

  For example, the display unit 4-250 may be controlled to display a button for selecting the selection-permitted paper on the screen so that a desired paper can be selected.

  To explain using the example of the management table 1800 in FIG. 18, for example, a paper selection key for selecting A4 nobi, a paper selection key for selecting A4, a paper selection key for selecting B5, and A5R A paper selection key for selecting, a paper selection key for selecting LTR, and a paper selection key for selecting STMT-R are displayed on the screen of FIG. Then, using these paper selection keys, a user can control a desired sheet to be used as the first type sheet so that the user can select it.

  In other words, the CPU circuit unit 122 selects selection candidates (in this example, at least eight candidates based on the management table 1800 in FIG. 18) that are prohibited from being used as a text sheet (first type). The operation unit 123 is controlled so that selection by the user is prohibited.

  For example, as the first type sheet, the sheet selection key for selecting a sheet to be prohibited from selection (here, eight sheets) controls the display unit 4-250 so as not to be displayed on the screen. Alternatively, the display of these paper selection keys itself may be permitted. For example, the display unit 4-250 is controlled so that these keys are displayed in gray or are displayed in a shaded manner. . As a result, a sheet that is not a selection target can be selected by the user.

  In the example of FIG. 7D, the CPU circuit unit 122 indicates that there are currently A4 size sheets in the three sheet feeding cassettes of the image forming apparatus, and the sheet presence / absence detection sensor of each sheet feeding cassette. Judgment based on information from. And it is an example at the time of reflecting the result on the said screen.

  In this case, the user can select one of the sheet cassettes 1 to 3 on the screen of FIG. 7D and set an A4 size sheet as a body sheet in the gluing process mode. Control.

  Of course, for example, in the state shown in FIG. 7D, any one of the above-described five paper candidates to be selected (A4 size sheet, B5 size sheet, LTR size sheet, STMT-R size sheet). The user can set such a sheet type sheet on the manual feed tray 227 of the image forming apparatus, and the user can select the manual feed tray 227 on the screen of FIG. As described above, the user can select a desired candidate from the selection-permitted paper candidates.

  In the present embodiment, as can be seen by referring to the management information defined in the management table 1800 in FIG. 18, the case binding mode is selected by the user even when the case binding mode is selected by the user. Even in such a case, a sheet that is allowed to be selected by the user as a text sheet (in this embodiment, it is also referred to as an intermediate sheet or a first type sheet). The candidates are common (same) in both cases.

  However, as shown in FIG. 18, it is not always necessary that the candidates for selection as a text sheet (medium paper) are the same in the case binding mode and the top glue binding mode.

  However, regardless of whether the case binding mode is selected or the case binding mode is selected, paper candidates that are prohibited from being used as a body sheet (corresponding to a first type sheet) in the management table 1800 of FIG. The CPU circuit unit 122 controls to prohibit the use of a large-size sheet such as a sheet candidate indicated by a cross in the table 1800 in FIG. 18 as a body sheet. .

  This control is also a consideration for the convenience of the mechanical configuration of the device itself, for example, when assuming an image forming system capable of performing gluing processing, due to the compact design, large size sheets cannot be glued. is there.

  Even if not, the above control is also a consideration for the user in consideration of market needs and the like as assumed in the prior art.

  For example, description will be made with reference to FIGS. 8A, 8B, 24A, 25A, and 26A. It is expected that the printed material corresponding to the final result created by the glue binding process includes many user manuals, guide books, and the like. In other words, the final output form of the glued and bound printed matter is likely to be a small size of A4 size or less, for example.

  In addition, in this embodiment, in the case binding mode, when a cover is fed, a large size sheet such as A3 size can be selected. However, the sheet (corresponding to the second type sheet) serving as the cover in the case binding mode is folded so as to cover the sheet bundle for the text when the gluing process by the gluing unit 300 is executed. That is, even if a printed material is created in the case binding mode, the final printed material size can be understood by comparing the rightmost diagram in FIG. 8A and the right diagram in FIG. 8B. As a result, the result is substantially the same size as the printed material of the top glue bookbinding. That is, both the case binding printed matter and the top glue bound printed matter have a final size not a large size such as A3 size but a small size such as A4 size.

  Based on this point of view, it is a market need for users to use a sheet for the main text as a full-size sheet in the gluing bookbinding process, where the final printed output size will be large. I think that it is very few even if it sees from. Rather, for example, even if the user can specify a large-sized sheet as a body sheet from the operation unit, it is more likely that the user himself has made an incorrect setting. Think.

  Therefore, the above control is also taken into consideration for such a user.

  As described above, according to the present embodiment, for example, when the gluing bookbinding mode is designated by the user, the CPU circuit unit 122 selects only the paper size that can be glued and bound according to the user setting. It is controlled so that it can be selected as paper (control is performed so that large-size paper that cannot be used as medium paper cannot be selected).

  In other words, the CPU circuit unit 122 controls only the cassette stages having the recording paper sizes that can be selected and specified as the intermediate sheets, and the user can select and specify a desired cassette stage from these. It is controlled so that it can.

  As a result, it is possible to prevent the occurrence of problems as envisaged in the prior art, and whether the user can perform large-size bookbinding (the bookbinding printed material has a large size as the final result such as A3). In this way, it is possible to prevent such a problem that printing on a large-size sheet and bookbinding are designated.

  In the above-described example, the control is related to the selection process for the text sheet when one of the sheet gluing processing modes of case binding and top binding is selected.

  This control is performed both when processing a case binding mode job and when processing a case binding mode job, as can be seen by referring to the management information in the management table 1800. Both cases are to be executed.

  In the present embodiment, for example, the CPU circuit unit 122 selects, for the case binding mode among the above-described two types of gluing processing modes, the process for selecting the sheet for the text (that is, the first type sheet). In addition, a control for selecting a case binding cover sheet (that is, a second type sheet) is also executed.

  As described above, the final print result subjected to the gluing process is a small size even if it is a case-bound printed product. However, it means that the size of the final printing result (for example, the rightmost example in FIG. 8C is the final case binding printing result) is a small size.

  Here, the text sheet (first type sheet) shown in the leftmost diagram of FIG. 8A and the case binding cover sheet (second type) shown in the middle figure of FIG. 8A. Sheet).

  The size of the first type sheet is the state before the case binding process is executed (see the leftmost drawing in FIG. 8A) and the state in which the case binding process is executed and the final printed matter is completed (FIG. 8). (See the figure at the right end of (a)), the sizes are the same (however, when the three-way cutting process is executed, the size is slightly reduced).

  On the other hand, the second type sheet is folded so as to cover the first type sheet bundle when performing the case binding process. That is, the state before executing the case binding process is a state as shown in FIG. As described above, the second type sheet looks like the right end of FIG. 8A when the final printed matter is completed. Before the case binding process is performed, the sheet bundle for the text is covered. A sheet with a size that can be used up is required.

  Therefore, in the present embodiment, for example, the following control is executed by the CPU circuit unit 122 as control related to the selection processing of the second type sheet in the case binding mode.

  For example, when the case binding process is performed based on the restriction information described in the management table of FIG. 18 described above, the CPU circuit unit 122 uses the user as a case binding cover sheet (second type sheet). To limit the sheet candidates that are allowed to be selected.

  For example, based on the restriction information described in the management table 1800 in FIG. 18, the CPU circuit unit 122 selects the paper selection candidates “A3 Nobi, A3, B4, A4R, 11 × 17, LGL, LTR-R” (FIG. 18). With regard to the paper selection candidate (circled with ○ mark indicating that use is permitted as a cover sheet in the case binding mode) in the case binding mode, the case binding cover sheet (second sheet) is displayed in the case binding mode. The user is allowed to select as a type sheet). Then, the user selects one sheet having a desired size from the selection permission candidates. For this purpose, for example, a display screen such as the display screen of FIG.

  In addition, based on the restriction information described in the management table 1800 in FIG. 18, the CPU circuit unit 122 selects a paper selection candidate (such as candidates “A5, A4, LTR, A5R, STMT-R, B5” other than the above) ( In the table of FIG. 18, for the case selection paper (marked with a cross indicating that use is prohibited as a cover sheet in the case binding mode), the case binding cover sheet (the first sheet is displayed in the case binding mode). Two types of sheets) are controlled so as to be prohibited from being selected by the user. For this purpose, for example, through the display screen of FIG. 7D, these candidate paper selection keys are displayed, grayed out, or grayed out so that the user cannot select these candidates for selection prohibition. The display unit 4-250 is controlled so as to display the shaded area.

  Note that the information in the management table 1800 in FIG. 18 includes restriction items (rules) for restricting sheet candidates that can be used in a job to be processed for each of a plurality of types of sheet processing modes included in the sheet processing apparatus 230. Similarly to the management information related to each restriction item in FIGS. 20, 37, and 38, the management information preliminarily registered in the hard disk of the image memory 120.

  As described above, according to the present embodiment, for example, control is performed so as to limit the sheets permitted to be used in the sheet gluing process in response to the selection of a sheet gluing processing mode such as the case binding mode or the top glue binding mode. To do.

  Then, based on the restriction information described in the management table of FIG. 18, when processing a job for which the sheet gluing processing mode has been selected, control is performed to prohibit the use of a predetermined sheet in the job. To do.

  In the present embodiment, for example, the management information in FIG. 18 uses the CPU circuit unit 122 for exclusive control between the selection of the sheet sheet processing mode for the job to be processed and the selection of the sheet to be used in the job to be processed. It is intended to be executed by.

  Therefore, in the present embodiment, for example, the following control may be executed using the management information of FIG.

  For example, in the case where the screen of FIG. 4 is displayed on the display unit 4-250, it is assumed that the user has not yet set any print conditions. FIG. 4 shows an initial screen. In other words, none of the operation modes of a plurality of types of sheet processing modes that can be executed by the sheet processing apparatus 230 is selected by the user.

  In this state, for example, it is assumed that the user presses the paper selection key 4-252 on the screen of FIG. In response to this, the CPU circuit unit 122 presents a sheet candidate that can be used in a job to be processed on the display unit 4-250, and a user selects a sheet of a desired size from the candidates. A paper selection screen (not shown) for enabling selection is displayed.

  As described above, when the sheet selection mode is instructed by the user when the sheet processing mode is not selected by the user, the CPU circuit unit 122 is entered in the left end column of the management table 1800 in FIG. All the paper selection candidates (A5 to N) are regarded as candidates for selection target permission. Then, the operation unit 123 is controlled via the above-described sheet selection screen (not shown) so that the user can select a desired candidate from these candidates.

  Then, on the sheet selection screen (not shown) displayed on the display unit 4-250, for example, it is assumed that an “A5” size sheet is selected by the user. In this case, when “A5 size” is selected by the user in the management table 1800 in FIG. 18, the CPU circuit unit 122 checks the sheet processing mode that should be prohibited from being executed in the job to be processed. As a result, in the job, control is performed to prohibit execution of the “case binding mode”, the “sheet binding mode”, the “saddle binding mode”, and the “punch processing mode”. However, control is performed so as to permit selection and execution of the “staple mode”. Then, display control based on the determination result is executed on the display unit 4-250, and control is performed so as to limit sheet processing modes that can be selected by the user.

  For example, when the user selects the “A5 size” sheet as described above and the user presses the sorter key 4-256 on the display screen in FIG. 4, the sheet processing mode as shown in FIG. The selection screen is displayed on the display unit 4-250. However, on the sheet processing mode selection screen, control is performed so that the above-described five sheet processing modes to be selected when an “A5 size” sheet is selected cannot be selected by the user. For example, in this example, the “case binding mode” key 1906, “sheet binding mode” key 1907, “saddle binding mode” key 1905, and “punch processing mode” key 1902 are all grayed out. Or shaded. As a result, these modes cannot be selected by the user. The control as described above is executed by the CPU circuit unit 122.

  Thus, in the present embodiment, for example, the CPU circuit unit 122 refers to the restriction item information in the management table 1800 in FIG. In response to determining that the sheet has a predetermined size that should not be selected in the gluing process mode, control is performed to prohibit the selection and execution of the sheet gluing process mode.

  On the other hand, for example, it is assumed that “A4 size” is selected by the user on a sheet selection screen (not shown) displayed on the display unit 4-250. In this case, based on the information in the management table 1800, for example, control is performed so as to permit execution of the “case binding mode” and the “sheet binding mode” in the job to be processed. Then, display control based on the determination result is executed on the display unit 4-250, and control is performed so as to limit sheet processing modes that can be selected by the user.

  For example, the sheet processing mode as shown in FIG. 19 is received when the user selects the “A4 size” sheet as described above and the user presses the sorter key 4-256 on the display screen of FIG. The selection screen is displayed on the display unit 4-250. At this time, the CPU circuit unit 122 controls to display the “case binding mode” key 1906 and “sheet binding mode” key 1907 on the screen of FIG. Then, the user controls to select a desired sheet gluing process among the two types of sheet gluing process modes.

  Thus, in the present embodiment, for example, the CPU circuit unit 122 refers to the restriction item information in the management table 1800 in FIG. In response to the determination that the sheet is of a predetermined size to be selected in the gluing process mode, control is performed to permit selection and execution of the sheet gluing process mode.

  By configuring in this way, the above-described effects related to the sheet gluing process can be obtained with improved operability for the user, and the effects are further improved.

  Next, the description returns to the point in time when the display screen of FIG. Note that this screen is a screen that is displayed on the display unit 4-250 when the key 803 on the screen of FIG. 6D is pressed and the sheet gluing processing mode is selected by the user. is there.

  A key 805 on the screen in FIG. 7D displayed on the display unit 4-250 by the display control of the CPU circuit unit 122 is a key for enabling the user to perform cover setting in the glue binding process mode. Via the key 805, control is performed so that the user can select whether or not to attach a cover to a body sheet on which body image data is printed in the glue binding process mode.

  Here, for example, when the key 805 is pressed by the user and the “next” key on the screen of FIG. 7D is pressed by the user, the CPU circuit unit 122 performs the glue binding process. Control to attach a cover in mode. That is, as described with reference to FIG. 8A, the case binding processing mode, which is one of the glue binding processing modes, is set for the job to be processed.

  On the other hand, it is assumed that the user presses the “next” key on the screen of FIG. 7D without pressing the key 805. In this case, the CPU circuit unit 122 controls to prohibit attaching a cover in the glue binding process mode. That is, as described with reference to FIG. 8B, the top glue binding mode, which is one of the glue binding processing modes, is set for the job to be processed.

  As described above, in the present embodiment, when the user sets the cover binding via the key 805 in the glue binding mode setting, the CPU circuit unit 122 sets the job to be processed in the case binding processing mode. It is determined that the job is to be processed. On the other hand, if the user has not made a setting for attaching a cover via the key 805, the CPU circuit unit 122 determines that the job to be processed is a job to be processed in the top-binding process mode.

  In this embodiment, the user himself / herself determines whether to set the case binding mode or the top binding processing mode for the job to be processed through the operation unit 123 using the method described above. It is controlled by the CPU circuit unit 122 so that it can be determined. However, a desired sheet process including the case binding mode and the top glue binding process mode may be configured to be selectable by the user by the following method.

  For example, when the sheet processing apparatus (bookbinding apparatus) 230 executes sheet processing for a job to be processed, the key 4-256 on the operation screen in FIG. 4 indicates the type of sheet processing to be executed by the user. This is an instruction key to enable setting. Therefore, in response to the key 4-256 on the screen of FIG. 4 being pressed by the user, the CPU circuit unit 122 displays a setting screen having keys 1901 to 1909 as shown in FIG. -250 to control display.

  FIG. 19 is a diagram illustrating an example of a user interface screen to be controlled in the present embodiment.

  In FIG. 19, a screen 1900 is a display screen for enabling the user himself to select the type of sheet processing to be executed by the sheet processing apparatus 230 for a job to be processed.

  When the key 1906 on the screen 1900 is pressed by the user, the case binding processing mode is set. When the key 1907 on the screen 1900 is pressed by the user, the top-binding process mode is set.

  With such a direct selection method, a desired type of gluing process among the two types of gluing processes of the case binding mode and the top glue binding mode may be selected. In any case, the present embodiment can be applied to any setting method as long as the user can perform a gluing process desired by the user.

  When the case binding mode is selected by pressing the key 1906 on the screen 1900 in FIG. 19, the CPU circuit unit 122 changes the display content on the display screen of the display unit 4-250 from the screen 1900 to FIG. The display unit 4-250 is controlled so that the display screens d) to (f) can be transitioned to.

  Then, the user can select a sheet to be used as a body sheet for a job to be processed in the case binding mode via the screen of FIG.

  Then, the user can select a sheet to be used as a cover sheet for the case binding processing target job via the screen of FIG. The control related to a series of print processes for the second type sheet in the case binding mode has been described in detail with reference to FIGS.

  On the other hand, when the sheet binding mode is selected by pressing the key 1907 on the screen 1900 in FIG. 19, the CPU circuit unit 122 changes the display contents of the display screen of the display unit 4-250 from the screen 1900 to FIG. 7. The display unit 4-250 is controlled so as to be able to transition to the display screen of (d). Then, the user can execute selection of a sheet to be used as a body sheet for a job to be processed in the top glue binding mode via the screen illustrated in FIG.

  Further, when the user selects the top glue binding mode, there is no need to select a cover sheet. Therefore, while setting the printing conditions for the job, the display unit 4-250 is controlled to prohibit the display of the setting screen of FIG. The printer unit 2 is controlled to prohibit selection of the cover for the case binding mode. Such control may be incorporated.

  By executing various controls including display control like this, an error in the device, such as inserting a case binding sheet or executing a gluing process on the output sheet of a job in the top glue binding mode, is performed. Operation can be prevented. In addition, it is possible to prevent an erroneous operation of the user, for example, by mistakenly executing the selection setting of the case cover sheet while the user is setting the sheet binding mode in the operation unit 123. . That is, the effect obtained in this embodiment can be further improved.

  Next, another example of controlling various predetermined processes that affect the sheet gluing process focused on in the present embodiment will be described.

  An image forming system 1000 according to the present exemplary embodiment includes a sheet processing apparatus 230 together with an image forming apparatus main body (such as a reader unit 1 and a printer unit 2). The sheet processing device 230 is controlled by the CPU circuit unit 122 so as to execute the sheet processing designated by the user among a plurality of types of sheet processing on the sheet fed from the image forming apparatus main body.

  The sheet processing apparatus 220 according to the present embodiment includes a stapling processing mode, a punching processing mode, a cutting processing mode, a shift paper discharge processing mode, a saddle stitch binding processing mode, two types of glue binding processing (case binding processing, and top binding binding). A plurality of types of sheet processing modes such as (processing) mode. The CPU circuit unit 122 controls the sheet processing apparatus 220 to execute the type of sheet processing designated by the user based on the management data in the management table 2000 of FIG.

  FIG. 20 is a diagram showing an example of a management table that stores management information for defining restrictions between a plurality of types of sheet processing modes that can be executed by the sheet processing apparatus of the present embodiment.

  The management table 2000 in FIG. 20 shows an example of a function management table. The management table 2000 is also stored in advance in a predetermined memory provided in the image forming apparatus, such as a hard disk of the image memory 120, for example, similarly to the management tables in FIGS.

  Based on the management information in the management table 2000, the CPU circuit unit 122 confirms sheet processing candidates that can be executed by the sheet processing apparatus 220.

  The information in the management table 2000 is management information that defines restrictions (rules) between a plurality of types of sheet processing modes included in the sheet processing apparatus 230. The CPU circuit unit 122 executes prohibition control and exclusive control between a plurality of sheet processing modes based on the management information. Further, display control based on the management information of the table 2000 is executed for the display unit 4-250. In FIG. 20, combinations between executable modes are represented by “◯”, combinations between non-executable modes are represented by “×”, and combinations between non-existent modes are represented by “−”. ing.

  Based on the above configuration, in the present embodiment, for example, the CPU circuit unit 122 displays the display keys 1901 to 1907 displayed on the display screen of FIG. This means that the display form is either grayed out or shaded. Thus, the display unit 4-250 is controlled by the CPU circuit unit 122 so as to present the user with sheet processing candidates that can be selected and executed for the job to be processed.

  The CPU circuit unit 122 controls so that the user can select a desired sheet process to be executed for a job to be processed by pressing any of the keys 1901 to 1907. .

  For example, when the key 1901 on the display screen 1900 is pressed by the user, the CPU circuit unit 122 sets the staple mode for the job to be processed. When the key 1902 on the display screen 1900 is pressed by the user, the punch mode is set. When the key 1903 on the screen 1900 is pressed by the user, the cutting mode is set. When the key 1904 on the screen 1900 is pressed by the user, the shift discharge mode is set. When the key 1905 on the screen 1900 is pressed by the user, the saddle stitch binding mode is set. When the key 1906 on the screen 1900 is pressed by the user, the case binding processing mode is set. When the key 1907 on the screen 1900 is pressed by the user, the top binding process mode is set.

  In response to the user's setting of various print processing conditions for the job to be processed being completed and the start key 4-241 of the operation unit 123 in FIG. 4 being pressed by the user, the CPU circuit unit 122 It is determined that an instruction to start processing of the job to be received is received from the user.

  When the operation mode selected by the user is the copy mode, the CPU circuit unit 122 responds to the input of the process start instruction by the user described above, and the process placed directly on the ADF of the reader unit 1 or the platen glass The reader unit 1 starts the reading operation of the document bundle of the target job. Then, a series of read image data of the job is stored in the hard disk of the image memory 120. Then, the printer unit 2 causes the sheet to be fed from a sheet feeding unit (corresponding to one of 227, 214, 215, 225, and 226) selected by the user. Then, the printer unit 2 prints the job data read from the image memory 120 on the sheet fed from the sheet feeding unit. Then, the sheet of this job is introduced into the sheet conveyance path inside the sheet processing apparatus 230 via the paper discharge roller 219.

  The image forming apparatus according to the present embodiment has not only a copy mode but also a plurality of operation modes such as a box mode. In the box mode, job data input from an external device (for example, the external device 2002 in FIG. 2) via the reader unit 1 or the network 2001 is converted into a predetermined area (box area) of the hard disk inside the image memory 120. This is a function for storing and holding the data. In addition, this function allows the user to operate the apparatus so that the printer unit 2 prints the desired image data from the user's desired box inside the hard disk at a desired timing. is there.

  Therefore, when the processing is received through the start key 4-241 while the box mode is selected by the user, the CPU circuit unit 122 starts a series of operations from the image data reading operation from the hard disk. The image memory unit 120 is controlled to start processing. The subsequent processing after reading from the image memory unit 120 is the same as the operation in the copy mode. In other words, the image data of the job read from the hard disk in the box mode is printed by the printing unit 2, and the sheet on which the printing process has been performed is passed through the sheet discharge roller 219 to the sheet conveyance path inside the sheet processing apparatus 230. To introduce.

  The CPU circuit unit 122 causes the sheet processing device 230 to execute the sheet processing corresponding to the sheet processing mode selected by the user by the sheet processing device 230 on the sheet of the job that has been printed by the printer unit 2. Control.

Here, a series of operations in various sheet processing modes shown in FIGS. 19 and 20 will be described.

  For example, before the user inputs a job processing start request by pressing the start key 4-241, when the user presses the key 1901 on the display screen 1900 shown in FIG. 19, the stapling mode is set for the job to be processed. Suppose that it was set by the user. In this case, the CPU circuit unit 122 causes the sheet processing apparatus 230 to execute the stapling process for the sheet of the job based on the job processing condition set by the user.

  For example, sheets of the job to be processed that are carried into the sheet processing apparatus 230 via the paper discharge roller 219 of the printer unit 2 are temporarily stacked on a processing tray provided in the staple unit 280. When a stack of sheets (for example, a job consisting of document data for a total of 5 pages) is stacked on the tray of the unit 280, the staple is made. A stapling process is executed by the unit 280. Then, after the stapling process is performed, the sheets of the job are bundled and discharged from the processing tray of the staple unit 280 to the tray 256 of the sheet processing apparatus 230. Such a series of processes is executed for the number of copies set by the user using the numeric keypad 4-245 before printing.

  On the other hand, it is assumed that the cutting process mode is set by the user for the job to be processed by pressing the key 1903 on the display screen 1900 shown in FIG. In this case, the CPU circuit unit 122 causes the sheet processing apparatus 230 to execute a cutting process on the sheet of the job (a process of cutting an end portion of the sheet) based on the job processing condition set by the user.

  For example, sheets of the job to be processed that are carried into the sheet processing apparatus 230 via the paper discharge roller 219 of the printer unit 2 are temporarily stacked on the trimmer table 255. When a sheet for one bundle of this job is stacked on the trimmer table 255 (for example, in the case of a job composed of a total of 30 pages of document data, this corresponds to a plurality of sheets for 30 pages). Then, the trimming unit 247 executes the cutting process. Then, the sheet bundle of the job that has been cut is discharged to the tray 257 of the sheet processing apparatus 230. Such a series of processes is executed for the number of copies set by the user using the numeric keypad 4-245 before printing.

  On the other hand, it is assumed that the user has pressed the key 1904 on the display screen 1900 shown in FIG. 19 so that the user has set the shift paper discharge processing mode for the job to be processed. In this case, based on the job processing conditions set by the user, the CPU circuit unit 122 performs shift paper discharge processing on the sheets of the job (a plurality of sheet bundles are ejected in a shifted state for each bundle. The sheet processing apparatus 230 executes the process of stacking on the paper tray.

  For example, the staple unit 280 is stacked when a bundle of sheets (for example, a job including a total of five pages of document data corresponds to a plurality of sheets of five pages) is stacked on the staple unit 280. On the 280 tray, control is performed so that the sheet bundle for one bundle is shifted in the front side of the apparatus or in the rear side of the apparatus by using the restriction plate of the unit. When the operation of shifting in one direction (shift operation) is completed, the sheet bundle is discharged onto the discharge tray 256. Then, the restriction plate of the unit 280 is controlled so that the subsequent sheet bundle to be discharged next to the sheet bundle is shifted on the tray on the staple unit 280 in the direction opposite to the preceding sheet bundle. . Then, the sheet bundle shifted in the opposite direction to the previous sheet bundle is discharged onto the previous sheet bundle already stacked on the discharge tray 256.

  As a result, the preceding sheet bundle and the succeeding sheet bundle can be stacked on the sheet discharge tray 256 while being shifted from each other in the front and back directions of the apparatus. Thereby, the cut | interruption of each part of a some sheet bundle can be clarified. Such a series of shift paper discharge processing is executed by the number of copies set by the user using the numeric keypad 4-245 before printing.

  On the other hand, it is assumed that when the user presses a key 1905 on the display screen 1900 illustrated in FIG. 19, the saddle stitch binding processing mode is set by the user for the job to be processed. In this case, the CPU circuit unit 122 causes the sheet processing apparatus 230 to execute saddle stitch binding processing for the sheets of the job based on the job processing conditions set by the user. Here, the saddle stitch bookbinding process will be described with reference to FIG.

  FIG. 39 is an explanatory diagram relating to saddle stitch bookbinding printing processing to be controlled in the present embodiment.

  For example, an A4 size job for 8 pages (corresponding to a series of input print data including 8 pages of document data 601 to 608 shown in FIG. 39A) is used to print a medium. A case of binding and binding will be described.

  When the user inputs a processing start instruction by pressing the start key 4-241, the job is stored in the hard disk of the image memory 120 in order of pages from the first page 601.

  When all the pages of data are stored in the hard disk of the image memory 120, one sheet of A3-sized recording paper is fed from the paper feed unit. Then, an image for a total of two pages, that is, the image on the fourth page and the image on the fifth page, is formed on the first surface of the first recording sheet. Then, the front and back of the sheet are reversed inside the image forming apparatus main body, the recording paper is re-fed, and the second surface of the first recording paper (opposite surface of the first surface) An image of the two pages of the image on the sixth page and the image on the third page is formed in an array. Thereby, the printing of the first recording sheet in FIG. 39B is completed. When printing is completed on the front and back surfaces of the first sheet, the sheets are temporarily stacked on a tray in the sheet processing apparatus 230.

  Next, another A3 size recording sheet is fed from the sheet feeding unit as the second recording sheet. Then, the two pages of the second page image and the seventh page image are arranged and formed on the first surface of the second recording sheet. Next, on the second side of the second recording sheet (opposite side of the first side), an image for the two pages of the image on the eighth page and the image on the first page is formed in an array. Thereby, the printing of the second recording sheet of FIG. 39B is completed.

  Then, when printing is completed on each of the front and back surfaces of the second sheet, the printed second sheet is placed on the first sheet that has already been waited by the sheet processing apparatus 230. Make it stack. When these second sheets are aligned, the center position of the sheet is set as a staple position, and the staple process is executed on this position (this corresponds to saddle stitching). After this saddle stitching process is executed, the sheet bundle is centered on the saddle stitching position (that is, the center position of the sheet), and the first page is the front cover side and the eighth page is the back cover side. In this way, the folding processing is executed by the sheet processing device 230 so as to be folded in half. When this bi-folding process is completed, for example, a bundle of sheets is discharged to the discharge tray 257. By causing the CPU circuit unit 122 to execute the above-described series of processing in the image forming system 1000, it is possible to create a saddle stitch bookbinding print result as shown in FIG.

  As described above, when processing a job in which the saddle stitch bookbinding processing mode is selected, the CPU circuit unit 122 controls to prohibit the gluing process to be executed in the case binding mode or the top binding mode.

  The CPU circuit unit 122 performs such a series of saddle stitch bookbinding processing for the number of copies set by the user using the numeric keypad 4-245 before printing, in the image forming apparatus main body and the sheet processing apparatus. 230 is controlled.

  As described above, in the present embodiment, for example, the bookbinding mode includes not only the above-described two types of gluing bookbinding modes but also the saddle stitch bookbinding mode that prohibits gluing processing. The bookbinding mode can be selected. By configuring in this way, it is possible to create bookbinding prints in various output forms, further meet various needs from users, and further improve the effects of the present embodiment. .

  Next, when the user presses a key 1906 on the display screen 1900 shown in FIG. 19, the case binding processing mode corresponding to one of the gluing processes is set by the user for the job to be processed. Will be described. In this case, the CPU circuit unit 122 causes the sheet processing apparatus 230 to execute the case binding process for the sheet of the job based on the job processing condition set by the user. A series of processing sequences of the case binding processing is as described above with reference to FIG. 8A and FIGS. Also, since it will be described later with reference to FIG. 11, it is omitted here.

  In addition, when the user presses a key 1907 on the display screen 1900 shown in FIG. 19, the user has set a top glue binding processing mode corresponding to another gluing process for the job to be processed. To do. In this case, the CPU circuit unit 122 causes the sheet processing apparatus 230 to execute a sheet binding process for the sheets of the job based on the job processing conditions set by the user. A series of processing sequences of the book binding process is as described above with reference to FIG. Also, since it will be described later with reference to FIG. 11, it is omitted here.

  As described above, the present embodiment displays the user interface screen on the display device and allows the user to select a desired type of sheet processing via the user interface. The image forming system is controlled mainly by 122. Of course, a selection method other than the selection method described above may be used. The present embodiment can be applied to any configuration as long as the user can select a desired sheet processing.

  As described above, the present embodiment is configured such that a plurality of types of sheet processing including at least one of gluing processing and case binding processing can be executed by the sheet processing apparatus 230. Then, the user is presented with candidates for executable sheet processing. The user can arbitrarily select a desired sheet process.

  Note that the image forming system according to the present embodiment has a configuration capable of generating an erroneous operation by the user on the assumption of the above configuration. In addition, it is possible to prevent a malfunction or trouble of the system from occurring due to an erroneous operation of the user. This not only solves the problem assumed in the prior art, but can further improve the effects obtained in this embodiment.

  For example, when a user selects a desired type of sheet processing via the screen 1900 of FIG. 19 for a job to be processed, selection of other types of sheet processing modes is prohibited. This is controlled by the CPU circuit unit 122.

  In addition, for example, for a job to be processed, a plurality of sheets, for example, two types, for example, within a predetermined restriction range in which the above problems do not occur from the above-described plurality of types of sheet processing modes. The CPU circuit unit 122 performs control so that the processing mode can be set.

  The CPU circuit unit 122 executes such sheet processing exclusive control (sheet processing function restriction control) for the job to be processed based on the function restriction information stored in the function management table 2000 of FIG. Thus, the present image forming system 1000 is controlled.

  For example, the CPU circuit unit 122 reads the function restriction information stored in advance in the table 2000 of FIG. 20 from the hard disk of the image memory 120 to the RAM 125, and sends the management information to the prohibition rule (in this embodiment, the restriction information). In accordance with the rule, prohibition control related to sheet processing by the sheet processing device 230 is executed based on the rule.

  For example, the user interface unit used in the image forming system 1000 (the operation unit 123 corresponds to the job from the reader unit 1, and the print setting screen such as the printer driver corresponds to the external device 2002 such as the host computer). It is assumed that the “case binding processing mode” is selected by the user via a display screen (for example, see FIG. 19) displayed by In this case, the sheet processing apparatus 230 is controlled to execute the case binding process on the sheet of the job to be processed.

  As described above, when the case binding processing mode is selected by the user, execution of the case binding processing is permitted for the sheet of the job to be processed. In addition, based on the prohibition rule of the table 2000 of FIG. 20, it is permitted to perform the cutting process on the sheet of the case binding job target job. However, the image forming system 1000 is controlled by the CPU circuit unit 122 so as to prohibit other types of sheet processing from being performed on the sheets of the job.

  Referring to the example of FIG. 20, in this case (when the case binding mode is selected by the user), the CPU circuit unit 122 performs the top-bound binding processing mode, the saddle stitch binding processing mode, the stapling processing mode, and the punch processing. These five types of modes, that is, the mode and the shift paper discharge processing mode, are determined to correspond to the sheet processing mode to be selected. Then, the sheet processing corresponding to these sheet processing modes is prohibited from being executed on the sheets of the case binding target job. In addition, control is performed so as to prohibit the user itself from selecting these modes.

  Further, for example, it is assumed that the “sheet binding process mode” is selected by the user via the user interface unit used in the image forming system. In this case, the sheet processing apparatus 230 is controlled so as to execute the sheet binding process for the sheet of the job to be processed.

  As described above, when the user selects the top-binding bookbinding processing mode, execution of the top-binding bookbinding processing is permitted for the sheet of the job to be processed. In addition, based on the prohibition rule in the table 2000 of FIG. 20, it is permitted to selectively execute the cutting process and / or the punching process for the sheet of the job to be bound with the top glue bookbinding process. However, the image forming system 1000 is controlled by the CPU circuit unit 122 so as to prohibit other types of sheet processing from being performed on the sheets of the job.

  In the example of FIG. 20, in this case (when the top-binding bookbinding mode is selected by the user), the CPU circuit unit 122 performs case binding processing mode, saddle stitching processing mode, stapling processing mode, shift rejection, These four types of paper processing modes are determined to correspond to the sheet processing mode to be selected. Then, the sheet processing corresponding to these sheet processing modes is prohibited from being executed on the sheet of the job to be bound with the top-sheet binding. In addition, control is performed so as to prohibit the user itself from selecting these modes.

  Also, for example, it is assumed that the “saddle stitching processing mode” is selected by the user via a user interface unit (in this example, the operation unit 123) used in the image forming system. In this case, the sheet processing apparatus 230 is controlled to execute the saddle stitch binding process on the sheet of the job to be processed.

  As described above, when the saddle stitch bookbinding processing mode is selected by the user, the execution of the saddle stitch bookbinding processing is permitted for the sheet of the job to be processed. In addition, based on the prohibition rule in the table 2000 of FIG. 20, the cutting process is also permitted to be performed on the sheet of the job to be saddle stitched. However, the image forming system 1000 is controlled by the CPU circuit unit 122 so as to prohibit other types of sheet processing from being performed on the sheets of the job.

  In the example of FIG. 20, in this case (when the saddle stitch binding mode is selected by the user), the CPU circuit unit 122 performs the case binding process, the top binding process, the staple process, the punch process, and the shift rejection. It is determined that these five types of paper processing correspond to the sheet processing mode to be selected. Then, the sheet processing corresponding to these sheet processing modes is prohibited from being performed on the sheet of the job to be saddle stitched. In addition, control is performed so as to prohibit the user itself from selecting these modes.

  Similarly, when the cutting process mode is selected by the user, execution of the cutting process is permitted for the sheet of the job to be processed. In addition, based on the prohibition rule of the table 2000 of FIG. 20, at least one of case binding processing, gluing binding processing, and stapling processing is performed on the sheet of the job to be cut. The execution of one sheet process is permitted. However, other types of sheet processing (in the example of FIG. 20, punch processing and shift paper discharge processing correspond to prohibited sheet processing) are executed on the sheet of the job to be cut. This system is controlled by the CPU circuit unit 122 so as to be prohibited.

  Also, when the stapling mode is selected by the user, when the punching mode is selected by the user, or when the shift discharge mode is selected, the corresponding management rule in the management table 2000 of FIG. Based on the above, the execution permission / prohibition of sheet processing is controlled.

  As described above, in the present exemplary embodiment, prohibition rules for a plurality of types of sheet processing modes that can be executed by the sheet processing apparatus 230 are provided in advance. Then, based on the prohibition rule, the CPU circuit unit 122 determines, based on the prohibition rule, a predetermined job among other sheet processes other than the selected sheet process for a job to be subjected to the sheet process selected by the user. Execution of sheet processing is permitted. However, other predetermined sheet processing is controlled so as to be prohibited for the sheet of the job to be processed.

  Here, regarding the various prohibition controls related to the sheet processing described above, focusing on glue binding processing such as case binding processing and top glue binding processing, the system of the present embodiment performs the following control. It is configured.

  In the present embodiment, a sheet processing mode of a type other than the case binding mode, and a predetermined type of sheet processing mode that should be a selection prohibition target when executing the case binding processing mode is set via the user interface unit. In response to the selection by the user, the CPU circuit unit 122 controls the image forming system to prohibit the case binding process from being performed on the sheet of the job to be processed.

  For example, in the prohibition control example of the management table 2000 in FIG. 20, at least one of these five types of sheet processing is selected: a top-bound binding mode, a saddle stitch binding mode, a staple processing mode, a punch processing mode, and a shift paper discharge mode. In response to the selection of the type of sheet processing mode by the user, the CPU circuit unit 122 causes the image forming system to prohibit the case binding processing from being performed on the sheet of the job to be processed. Control.

  However, it is different from the above-described predetermined type of sheet processing (herein referred to as the first predetermined type of sheet processing), and is different from the predetermined type of sheet processing (herein referred to as the second predetermined type of sheet processing). ) Is selected, the image forming system 1000 is controlled so as to permit the case binding process to be executed for a job sheet for which the processing condition is set.

  For example, when the cutting process mode is selected by the user via the user interface unit such as the operation unit 123, it is permitted to execute the case binding process on the sheet of the job to be cut. Thus, the CPU circuit unit 122 controls the image forming system 1000. The following control is performed also in the sheet binding processing mode.

  In the present embodiment, a sheet processing mode of a type other than the top-binding bookbinding mode, and a predetermined type of sheet processing mode to be a selection prohibition when executing the top-binding bookbinding processing mode, the user interface unit is selected. In response to the selection by the user, the CPU circuit unit 122 causes the CPU circuit unit 122 to prohibit the execution of the book binding process on the sheet of the job to be processed. Control the forming system 1000.

  For example, a description will be given using a prohibition control example of the management table 2000 of FIG. The user selects at least one of these four types of sheet processing modes, such as case binding processing mode, saddle stitch binding mode, stapling processing mode, and shift discharge mode. In response to this, the image forming system 1000 is controlled by the CPU circuit unit 122 so as to prohibit the sheet binding process from being performed on the sheet of the job for which the processing condition is set.

  However, different from the above-described predetermined type of sheet processing (herein referred to as the third predetermined type of sheet processing), another predetermined type of sheet processing (herein referred to as the fourth predetermined type of sheet processing). ) Is selected, the image forming system is controlled so as to permit execution of the tenfold bookbinding process for the sheet of the job for which the processing condition is set.

  For example, when the cutting process mode and / or the punch process mode is selected by the user via the user interface unit such as the operation unit 123, the sheet of the job to be processed is selected. The CPU circuit unit 122 controls the image forming system 1000 so as to permit the execution of the glue binding process.

  In addition, as described above, when a predetermined type of sheet processing mode is selected by the user, control is performed so as to permit other types of sheet processing to be executed together. Whether or not to actually execute the sheet processing corresponding to the sheet processing mode to be performed is controlled by the CPU circuit unit 122 so as to be selectable by the user himself / herself.

  For example, when the sort key 4-256 on the screen of FIG. 4 is selected by the user, the user can select the type of sheet processing to be executed for the processing target job shown in FIG. The display screen 1900 is displayed on the display unit 4-250.

  Assume that the staple key 1901 is selected by the user on the display screen of FIG. Then, the CPU circuit unit 122 changes the display state of the display unit 4-250 to the display screen shown in FIG. 21 based on the restriction information described in the management table 2000 of FIG. 250 is controlled.

  FIG. 21 is a diagram showing an example of a user interface screen to be controlled in the present embodiment. The same components as those in FIG. 19 are denoted by the same reference numerals.

  In the present embodiment, as shown in FIG. 21, in the sheet processing setting screen in a state where the staple key 1901 is pressed, the CPU circuit unit 122 displays an effective display state for the punch key 1902, the cutting key 1903, and the shift paper discharge key 1904. To. Further, the saddle stitch binding key 1905, the case binding key 1906, and the top binding book key 1907 are displayed in gray out, and these keys are made unselectable by the user.

  The CPU circuit unit 122 performs display control in this manner, so that at least one of the sheet processing mode of the punch mode, the cutting mode, and the shift discharge mode is selected for the job for which the staple mode is selected. Selectable by the user. However, control is performed so that selection by the user is prohibited for the saddle stitch binding mode, the case binding mode, and the top binding mode.

  Also, for example, it is assumed that the case binding key 1906 is selected by the user on the display screen 1900 of FIG. Then, the CPU circuit unit 122 causes the display unit 4-250 to change the display state of the display unit 4-250 to the display screen shown in FIG. 22 based on the restriction information described in the management table 2000 of FIG. 250 is controlled.

  FIG. 22 is a diagram showing an example of a user interface screen to be controlled in the present embodiment, and the same components as those in FIG. 19 are denoted by the same reference numerals.

  In the present embodiment, as shown in FIG. 22, on the sheet processing setting screen in a state in which the case binding key 1906 is pressed, the CPU circuit unit 122 sets the trimming key 1903 to an effective display state. Further, the staple key 1901, the punch key 1902, the shift discharge key 1904, the saddle stitch bookbinding key 1905, and the top binding bookbinding key 1907 are grayed out, and these keys cannot be selected by the user.

  By controlling the display in this way, the cutting mode can be selected by the user for a job for which the case binding mode is selected. However, the user is prohibited from selecting the staple mode, the punch mode, the shift paper discharge mode, the saddle stitch binding mode, and the top binding mode.

  In addition, for example, it is assumed that the top glue binding key 1907 is selected by the user on the display screen 1900 of FIG. Then, the CPU circuit unit 122 changes the display state of the display unit 4-250 to the display screen shown in FIG. 23 based on the restriction information described in the management table 2000 of FIG. 250 is controlled.

  FIG. 23 is a diagram showing an example of a user interface screen to be controlled in the present embodiment, and the same components as those in FIG. 19 are denoted by the same reference numerals.

  In the present embodiment, as shown in FIG. 23, on the sheet processing setting screen in a state where the top-binding bookbinding key 1907 is pressed, the CPU circuit unit 122 puts the punch key 1902 and the cutting key 1903 into an effective display state. However, the staple key 1901, the shift discharge key 1904, the saddle stitch bookbinding key 1905, and the case binding key 1906 are grayed out, and these keys cannot be selected by the user.

  By controlling the display in this manner, the user can select at least one of the sheet processing mode of the punch processing mode and the cutting mode for the job for which the sheet binding mode is selected. However, the staple mode, the shift paper discharge mode, the saddle stitch binding mode, and the case binding mode are controlled to be prohibited from being selected by the user.

  As described above, not only the actual sheet processing operation itself but also the operation control for the user interface unit is executed, so that the operability in particular among the above effects can be further improved. .

  In the above-described example, it is configured that the user can select whether or not to perform the cutting process on the sheet of the job that is the case binding process target, based on the user's own determination. However, in the present embodiment, the following control may be executed.

  For example, as described above, when the user selects the case binding processing mode, in response to the selection of the case binding mode, the cutting process is automatically performed on the sheet of the job that is the case binding processing target job. The sheet processing apparatus 230 may be configured to be controlled by the CPU circuit unit 122 so as to be executed.

  As described above, when the case binding mode is selected by the user for the job to be processed, the CPU circuit unit 122 makes its own determination on the case binding regardless of whether the user selects the cutting processing mode. It may be configured to determine whether or not to execute the cutting process on the sheet of the job to be processed.

  Also, for example, when the user selects a top-binding bookbinding processing mode, in response to the selection of the top-binding bookbinding mode, the cutting process is automatically executed on the sheet of the job to be processed by the top-bound bookbinding Thus, the sheet processing apparatus 230 is controlled by the CPU circuit unit 122.

  As described above, when the user selects the top binding mode for the job to be processed, the CPU circuit unit 122 makes an independent determination regardless of whether the user selects the cutting processing mode. Whether or not to perform the cutting process on the sheet of the job to be processed by the book binding process may be determined.

  It should be noted that, as in the various examples described above, when the cutting process is executed on a job that executes the sheet gluing process (when the user explicitly instructs the execution of the cutting process, and automatically the CPU circuit unit 122). The CPU circuit unit 122 controls to execute the above-described three-way cutting process.

  By configuring as described above, for example, in a situation where the appearance of the end portion of the sheet of the output result of the glued and bound printed matter is deteriorated unless the cutting process is performed, the user should execute the cutting process. Even if the user forgets to input “” from the operation unit, the image forming system 1000 can create a beautiful glue-bound printed material.

  Next, the user operation after the display screen of FIG. 7 is displayed on the display unit 4-250 will be described.

  When the key 805 is pressed (the “next” key is pressed after the key 805 is pressed) and case binding is designated, the CPU circuit unit 122 displays the liquid crystal display unit 4-250 in FIG. The operation screen shown is displayed. As described above, in the operation screen of FIG. 7F, in the case binding mode, the recording paper size of the cover sheet, the selection of the cassette stage (paper feed position), the presence / absence of copying on the cover sheet, and the like are controlled to be selectable. .

  In this example, the CPU circuit unit 122 controls to select only a cassette stage having a recording paper size that can be selected and specified as a cover sheet, and the user selects and specifies a desired cassette stage from among them. Can do.

  As shown in FIG. 7F, in the case binding mode, the recording paper size that is allowed to be selected by the user as the cover (second type sheet) is based on the restriction information in the management table 1800 in FIG. In the present embodiment, the control is performed so that “A3 Novi, A3, B4, A4R, 11 × 17, LGL, LTR-R”. Further, as described with reference to FIGS. 24 to 35, in the case binding mode, whether or not the cover (second type sheet) is copied to the front, whether or not the cover is copied to the back, and the back cover is back to the front It is possible to select whether to copy or not to copy the back cover. By selecting these items and pressing the “Next” key, the setting of case binding is completed.

  On the other hand, when the key 804 is selected and the “OK” key is pressed on the operation screen of FIG. 6C, the CPU circuit unit 122 detects this operation and causes the liquid crystal display unit 4-250 to perform saddle stitching. An operation screen shown in FIG. 7G for setting bookbinding is displayed.

  As shown in FIG. 7E, in the case of saddle stitch bookbinding (bookbinding mode in which no gluing process is executed), the paper size permitted to be selected by the user as the recording paper to be saddle-stitched bookbinding printed is shown in the management table of FIG. Based on the restriction item information of 1800, in the present embodiment, control is performed such that “A3, B4, A4R, 11 × 17, LGL, LTR-R”. When these are selected and the “next” key is pressed, the CPU circuit unit 122 causes the liquid crystal display unit 4-250 to display the operation screen shown in FIG. In the operation screen of FIG. 7G, “saddle stitching / not saddle stitching” can be selected. By selecting these items and pressing the “Next” key, the saddle stitch bookbinding setting is completed.

  Various processing conditions set for a job to be processed by the user via the user interface of the present embodiment including the above-described FIGS. 4 to 7 and FIGS. 19 to 23 are set as setting information by the user. It is assumed that the image data is stored in the RAM 125 included in the image forming system 1000. Then, the CPU circuit unit 122 is configured to use this information for comparison processing with the above-described various restriction information and various determination processing of flowcharts described later.

  Hereinafter, an image storage method and a reading method will be described with reference to FIGS.

  FIG. 9 is a schematic diagram showing a memory map of the image memory 120 shown in FIG.

  As shown in FIG. 9, the image memory 120 includes a layout memory 5000 and a plurality (100 in this embodiment) of storage memories 1 (5001) to 100 (5100), and 100 images are stored. It is configured so that it can be stored.

  FIG. 10 is a diagram for explaining an image storing method and a reading method for the image memory 120 shown in FIG.

  FIG. 10 (1) shows the storage capacity of one storage memory shown in FIG. 9. In this embodiment, A3 size storage is possible on the basis of 600 dpi, and it is composed of 7015 vertical × 9920 horizontal bits. Is done. This storage area is configured to store 100 images as one layout memory (image layout area), one character data, and an image storage area.

  Next, an example in which an A4 document image is stored in the image memory will be described with reference to FIG. Hereinafter, the control is performed by the CPU circuit unit 122 shown in FIG.

  As shown in FIG. 10 (2a), the A4 document placed on the platen glass surface 102 (FIG. 1) is sequentially read in the direction of the arrow as shown in FIG. 10 (2a).

  At this time, as shown in FIG. 10 (2b), the address (0, 0) of the storage memory (for example, storage memory 1 (5001)) for storing the read image data is counted up in the X direction, Specify the direction count up.

  When the first line is read, the read image data of the first line is sequentially written from the address (0, 0) to the address (0, 7015). Next, when the second line is read, the counter in the X direction is incremented by 1, and the read image data of the second line is sequentially written from the address (1, 0) to the address (1, 7015) direction. Next, when the third line is read, first, the counter in the X direction is incremented by 1, and the read image data of the third line is sequentially written from address (2,0) to address (2,7015). In this way, reading and writing are repeated until the address (4960, 7015) is written.

  Next, processing for reading image data written in the storage memory as shown in FIG. 10 (2) by rotating it 90 degrees clockwise from the storage memory will be described with reference to FIG.

  When the data stored in the storage memory (for example, the storage memory 1 (5001)) is rotated 90 degrees clockwise and read, the address (4960, 0) is first set to the start position as shown in FIG. In addition, the X direction counter is sequentially counted down and the Y direction counter is designated as up, and the X counter is sequentially decreased from the address (4960,0) to the address (0,0) direction for the first line image data. Read while. Next, the Y counter is incremented by 1, and the image data of the second line is read from the address (4960, 1) to the address (0, 1). By sequentially reading in this way, as shown in FIG. 10 (3b), it is possible to read image data rotated 90 degrees clockwise from the storage memory.

  Next, processing for reading image data written in the storage memory as shown in FIG. 10 (2) without rotating from the storage memory will be described with reference to FIG.

  When reading the data stored in the storage memory (for example, the storage memory 1 (5001)) without rotating, as shown in FIG. 10 (4a), first, the address (0, 0) is set to the start position in the X direction. And the Y-direction counter is designated to be up, and the image data of the first line is read out from the address (0,0) to the address (0,7015) direction while sequentially increasing the Y counter. Next, the X counter is incremented by 1, and the image data of the second line is read from the address (1, 0) to the address (1, 7015). By sequentially reading in this manner, the image data can be read from the storage memory as shown in FIG. 10 (4b).

  Therefore, by reading an A4 width document shown in FIG. 10 (2a) in the direction of FIG. 10 (4a), the image can be read without rotating.

  Next, a process of reading image data written in the storage memory as shown in FIG. 10 (2) by rotating it 180 degrees from the storage memory will be described with reference to FIG.

  When the image data stored in the storage memory (for example, the storage memory 1 (5001)) is rotated 180 degrees and read out, as shown in FIG. 10 (5a), first, the address (0, 7015) is set to the start position. The X-direction counter is designated as countdown and the Y-direction counter is designated as countdown, and the image data for the first line is read from the address (4960, 7015) in the address (4960,0) direction while the Y counter is sequentially reduced. . Next, the X counter is decremented by 1, and the image data of the second line is read from the address (4959, 7015) to the address (4959, 0). By sequentially reading in this manner, the image data can be read from the storage memory as shown in FIG. 10 (5b).

  Therefore, an image rotated 180 degrees can be read by reading the A4 width document shown in FIG. 10 (2a) in the direction of FIG. 10 (5a).

  Next, a process of reading image data written in a plurality of storage memories and combining them on the layout memory 5000 will be described with reference to FIG.

  As shown in FIGS. 10 (6a) and 10 (6b), images individually stored in the storage memories (for example, the storage memory 1 (5001) and the storage memory 2 (5002)) are read, and FIG. As shown in FIG. 5, by writing an image at a desired position in the layout memory 5000, different document images can be synthesized on the image memory 120.

[Description of Printer 2]
The configuration and operation of the printer unit 2 will be described below with reference to FIG.

  In the printer unit 2 of FIG. 1, reference numeral 210 denotes an exposure control unit that converts an image signal input to the printer unit 2 into a modulated optical signal and irradiates the photosensitive member 211 via the mirror 207. The latent image created on the photoconductor 211 by this irradiation light is developed by the developing device 212. The transfer paper is conveyed from any one of the transfer paper stacking portions 214, 215, 225, 226, and the manual paper feed portion 227 in synchronization with the leading edge of the developed image, and the developed image is transferred to the transfer paper by the transfer portion 216. Is transcribed. The transfer sheet on which the image has been transferred is fixed to the transfer sheet by the fixing unit 217, and then guided to the sheet discharge roller 219 via the conveyance direction switching member 220 and passes through the sheet discharge sensor 218. The paper is discharged to the bookbinding unit 230 by the paper discharge roller 219.

  A method of outputting sequentially read images on both sides of one output sheet will be described.

  The output paper fixed by the fixing unit 217 is once transported to the paper discharge roller 219, and then transported to the re-feeding transfer paper stacking unit 221 via the transport direction switching member 220 with the paper transport direction reversed. . When the next original is prepared, the original image is read in the same manner as in the above process, but the transfer paper is fed from the refeed transfer paper stacking unit 221. Two original images can be output on the back side.

  The transfer paper output from the paper discharge roller 219 is delivered to the bookbinding unit 230. The bookbinding unit 230 is a post-processing device capable of executing a gluing bookbinding process (case binding process, top glue bookbinding process) on the recording paper printed out from the printer unit 2.

  The bookbinding unit 230 performs post-processing by changing the traveling direction of the transfer paper according to the processing content. When the punch function is working, the direction changing materials 232 and 235 are controlled and guided to the punch unit 290 in order to punch holes in the punch unit 290. Similarly, when the stapling function is working, the direction change members 232 and 235 are controlled in order to perform stapling in the staple unit 280. The staple unit 280 performs stapling according to the type of staple. The transfer sheet processed by the punch unit 290 and the staple unit 280 is discharged to a discharge tray 256.

  When glue binding is designated, the transfer paper is guided to the glue unit 300 by controlling the direction change members 232 and 235. Note that the transfer paper glued and bound by the gluing unit 300 is discharged to the paper discharge tray 257.

  Further, when each post-processing by the punch unit 290, the staple unit 280, and the gluing unit 300 is not performed, the transfer paper is discharged to the paper discharge tray 257.

  The paper discharge trays 256 and 257 are provided with a sensor (not shown) capable of detecting the stacking amount of the discharged transfer paper, and the CPU circuit unit 122 determines whether the paper discharge tray is based on the detection result of the sensor. Whether or not paper can be discharged can be determined.

  Hereinafter, the case binding operation of attaching a cover by the bookbinding unit 230 will be described with reference to FIGS.

  11 and 12 are diagrams for explaining the operation of case binding for attaching a cover by the bookbinding unit 230 shown in FIG. In FIG. 11A to FIG. 11C, the recording paper 701 is shown thick. However, this is a display for clearly indicating the position of the paper, and there is only one recording paper 701. On the other hand, the middle paper 801 in FIGS. 12D to 12G indicates a paper bundle.

  As shown in FIG. 11A, the direction changing material 232 changes the direction so as to guide the transfer paper 701 to the transfer paper path 233. It is conveyed by rollers 270 and 271. Subsequently, as shown in FIG. 11B, the direction changing material 235 changes the direction so as to guide the transfer paper 701 to the stack unit 236, and the transfer paper 701 is stacked as shown in FIG. 11C. Housed in part 236. Similarly, all the case binding medium sheets are stored in the stack unit 236.

  Subsequently, as shown in FIG. 12D, a case binding cover 802 is conveyed. The direction is changed so that the direction changing material 232 guides the cover to the cover path 234. The rollers 243 and 239 are rotated so that the half of the cover sheet is located at the half of the rollers 243 and 239.

  At this time, the glue is applied to the transfer paper by moving the glue unit 300 from the front to the back. As shown in FIG. 1, the gluing unit 300 includes a gluing part 301, a heater part 302, and a sensor part 303. The gluing unit 300 can be glued by heating solid gluing to a predetermined temperature in the heater part 302. Yes. At this time, the temperature is detected by the sensor unit 303 so that the glue does not rise above a predetermined temperature.

  Next, the glued inner paper is glued to the cover.

  As shown in FIG. 12E, the gluing unit 300 retreats to a predetermined position by the rotation of the rollers 237 and 238, and rotates so that the rollers 272 and 273 move the middle paper downward. The rollers 273 and 273 stop rotating until the middle sheet reaches the cover. Leave in this state for a predetermined time. Gluing is performed as described above. At this time, in order to fold the cover, the folding material 277 operates to weave the cover. Here, if the number of sheets is small when the folded material 277 operates, “wrinkles” and “breakage” occur on the cover. For this reason, when carrying out case binding, there is a restriction on the minimum number of sheets that can be processed (needs to be restricted).

  Subsequently, as shown in FIG. 12 (f), the member 242 at the gluing position is moved, and the member 242 is moved so as to guide the end portion to the cutting position in order to align the ends of the bound book. . At this time, the members 274 and 275 move so as to knock down the glue binding (the inner paper 801 and the cover 802 are glued).

  As shown in FIG. 12G, the position on the trimmer turntable 255 is controlled by the position control member 252 moving. The bookbinding stacked on the trimmer turntable (in which the cover 802 is glued to the middle paper 801) is cut at the end by the cutter 248 coming out of the trimmer unit 247 ascending and descending. The trimmer turntable 255 can cut three sides of the sheet by rotating 90 degrees and 180 degrees. The cut bookbinding is discharged to the tray 257 when the position control member 252 moves in the direction of the tray 257 and the rollers 249, 253, 251, and 254 rotate.

  Next, a description will be given of book binding with no cover.

  Since the cover is not attached in the case binding, the operations of FIG. 11 (b) and FIG. 12 (e) are omitted from the case binding operation of FIG. 11 (a) to FIG. 12 (g). In this manner, since the operation of FIG. 12E is omitted, the maximum number of sheets that can be processed as in case binding does not occur in the case binding (there is no need to limit).

  Hereinafter, the case binding and top glue binding control in this embodiment will be described with reference to FIGS.

  FIG. 13 is a flowchart showing an example of a first control processing procedure in the image forming apparatus of the present invention. The processing of this flowchart is realized by the CPU circuit unit 122 shown in FIG. 2 loading a program stored in the ROM 124 or a hard disk in the image memory 120 or another storage medium (not shown) into the RAM 125 and executing it. In the figure, S9-1 to S9-22 indicate each step. Further, in the present embodiment, the gluing unit 300 can perform gluing processing at the same time by the gluing unit 300, which is the minimum processable number of sheets that indicates the minimum number of sheets that can be glued for the middle sheet and the cover that are the body text in case binding processing. The maximum processable number indicating the maximum number is set to 150.

  When the start key 4-241 shown in FIG. 4 is pressed, the CPU circuit unit 122 starts processing (S9-1), feeds a document from the document feeder 101, and causes the reader unit 1 to read the document. (S9-2) Based on the read result and the setting information stored in the RAM 125, the number of sheets to be printed out (hereinafter referred to as the number of printed sheets) is calculated and determined (S9-3). Note that the “number of printed sheets” here corresponds to the “total number N of sheets” described above (FIG. 36).

  Next, the CPU circuit unit 122 determines whether or not case binding is set based on the setting information stored in the RAM 125 (S9-4), and the case binding based on the setting information stored in the RAM 125. When it is determined that “NO” is set, the process proceeds to step S9-5, and the CPU circuit unit 122 determines whether the number of printed sheets is equal to or greater than the minimum processable number.

  If the CPU circuit unit 122 determines in step S9-5 that the number of prints is equal to or greater than the minimum processable number, the process proceeds to step S9-6, and the CPU circuit unit 122 determines that the number of prints is the maximum processable number. If it is determined whether or not the maximum number of sheets that can be processed is exceeded, the process advances to step S9-7 to execute printing, perform case binding processing, and end the processing (9-). 22).

  On the other hand, when the CPU circuit unit 122 determines in step S9-5 that the number of prints is not equal to or greater than the minimum processable number (less than the minimum processable number), or in step S9-6, the number of prints is the maximum processable number. If it is determined that the number of trays has been exceeded, the process advances to step S9-8 to determine whether there is a tray that can be ejected.

  If the CPU circuit unit 122 determines in step S9-8 that there is no tray that can be ejected, the message screen shown in FIG. 14A or 14B is displayed on the liquid crystal display unit in step S9-9. 4-250, and control to interrupt printing, and the process proceeds to step S9-10.

  FIG. 14 is a schematic diagram showing an example of a message screen at the time of case binding and top glue binding processing in the image forming apparatus of the present invention.

  FIG. 14A corresponds to a message screen displayed when it is determined that the number of printed sheets is not equal to or greater than the minimum number during the case binding process, and FIG. 14B illustrates the maximum number of printed sheets during the sheet binding process. Corresponds to the message screen when it is determined that the number has been exceeded.

  In FIG. 14, reference numeral 1101 denotes a cancel key. By pressing this key, the print job can be canceled.

  Returning to the flowchart of FIG.

  In step S9-10, the CPU circuit unit 122 determines whether or not to continue printing based on whether or not the cancel key 1101 in FIG. 14A or 14B is pressed, and the cancel key 1101 is not pressed. If it is determined to continue printing, the process proceeds to step S9-11, printing is performed (however, the case binding process is prohibited), and the process is terminated (S9-22).

  On the other hand, in step S9-10, if the CPU circuit unit 122 detects that the cancel key 1101 in FIG. 14A is pressed and determines that printing does not continue, the process is performed without executing printing. Is finished (S9-22).

  On the other hand, if the CPU circuit unit 122 determines in step S9-8 that there is a tray that can be ejected, in step S9-12, printing is performed and the sheet is ejected to the ejectable tray (however, The execution of the case binding process is prohibited), and the process ends (S9-22).

  On the other hand, if the CPU circuit unit 122 determines in step S9-4 that case binding is not set, it is determined in step S9-13 whether top binding is set, and the top binding is determined. If it is determined that bookbinding is set, the process proceeds to step S9-14, and the CPU circuit unit 122 determines whether the number of prints exceeds the maximum processable number.

  In step S9-14, if the CPU circuit unit 122 determines that the number of prints does not exceed the maximum processable number, the process proceeds to step S9-15 to execute printing and perform a book binding process. The process ends (S9-22).

  On the other hand, if the CPU circuit unit 122 determines in step S9-14 that the number of prints has exceeded the maximum processable number, the process proceeds to step S9-16 to determine whether there is a tray that can be ejected. If it is determined that there is no tray that can be ejected, in step S9-17, the message shown in FIG. 14C is displayed on the liquid crystal display unit 4-250, and control is performed so that printing is interrupted. Proceed to -18.

  In step S9-18, the CPU circuit unit 122 determines whether or not to continue printing depending on whether or not the cancel key 1101 in FIG. 14C is pressed, and determines that printing is continued without the cancel key 1101 being pressed. In this case, the process proceeds to step S9-19, where printing is executed (however, the execution of the book binding process is prohibited), and the process is terminated (S9-22).

  On the other hand, if the CPU circuit unit 122 detects that the cancel key 1101 in FIG. 14A is pressed and determines not to continue printing in step S9-18, the process is performed without executing printing. Is finished (S9-22).

  On the other hand, if the CPU circuit unit 122 determines in step S9-16 that there is a tray that can be ejected, printing is performed in step S9-21, and the print result is ejected to the tray that can be ejected ( However, the execution of the sheet binding process is prohibited), and the process ends (S9-22).

  On the other hand, if the CPU circuit unit 122 determines in step S9-13 that no top binding is set, printing is executed in step S9-20, and the process ends (S9-22).

  As described above, when the number of printed sheets (the number of recording sheets printed out from the printer unit 2) is less than the minimum processable number, the CPU circuit unit 122 only executes the case binding process by the glue binding unit. If the maximum number of sheets that can be processed is exceeded, prohibiting the execution of case binding processing and top glue binding processing by the gluing bookbinding unit will reduce the size of the gluing bookbinding unit. It is possible to suppress the occurrence of the failure of the resulting glue binding unit.

  Hereinafter, an example is given and it demonstrates more concretely.

(Specific example 1)
For example, 50 A4 size double-sided originals are stacked on the original feeder 101, A4 size recording paper is placed in the cassette 214, and a free size (297 mm x 424 mm A4 size recording paper + 4 mm back) on the manual feed tray 227. Load the recording paper. Then, in accordance with the operation flow shown in FIGS. 6 and 7, the case binding is set, and the start key 4-241 is pressed. Then, the process starts (S9-1), and a document is fed from the document feeder 101 and 50 sheets are read by double-sided scanning (S9-2). That is, the total original 100 surface is read.

  In step S9-2, since the number of original pages is 100, it is determined that double-sided printing results in 50 sheets, and the number of printed sheets is determined to be “50”. For example, when settings such as single-sided printing or 2-in-1 are set, the number of prints is determined according to these settings. For example, when single-sided printing is set, the number of printed sheets is fixed to 100, and when 2 in 1 is set, the number of printed sheets is fixed to 25.

  Next, in step S9-4, it is determined that it is case binding and the process proceeds to step S9-5. In this example, the number of prints is 50 and the minimum processable number is 10. Therefore, it is determined that the number of prints is equal to or greater than the minimum processable number, and the process proceeds to step S9-6. In this example, the number of prints is 50 and the maximum number of sheets that can be processed is 150. Therefore, in step S9-6, it is determined that the number of prints does not exceed the maximum number of sheets that can be processed, and the process proceeds to step S9-7. Then, printing is performed and case binding is performed, and the process is terminated (S-922).

(Specific example 2)
Next, 5 double-sided originals A4 size are stacked on the original feeder 101, A4 size recording paper is placed in the cassette 214, and a free size is placed on the manual feed tray 227 (297 mm × 424 mm, A4 size recording paper plus 4 mm back). An example of setting the recording paper will be described.

  When the case binding is set and the start key 4-241 is pressed according to the flow of the operation procedure shown in FIGS. 6 and 7, the process proceeds to step S9-1 to start the process, and the document feeder 101 starts the document. Is fed and 5 sheets are read by double-sided scanning. That is, the total original 10 side is read. Proceeding to step S9-2, since the number of original pages is 10, it is determined that double-sided printing will be 5, and the number of prints is fixed to “5”.

  In step S9-4, it is determined whether or not case binding is performed. In this example, since case binding is performed, the process advances to step S9-5 to determine whether the number of printed sheets is equal to or greater than the minimum processable number. In this example, since the number of prints is 5 and the minimum processable number is 10, it is determined that the number of prints of 5 is not 10 or more and cannot be processed, and the process proceeds to step S9-8.

  Next, in step S9-8, it is determined whether there is a tray that can be ejected. If it can be discharged to the tray 256 shown in FIG. 1, the process proceeds to step S9-12 to perform printing (but without case binding), and discharges to the tray 256.

  On the other hand, if there is no tray that can be ejected in step S9-8, the process proceeds to step S9-9 to display the message screen shown in FIG. The user can cancel the print job by pressing the cancel key displayed in FIG.

  In step S9-8, even if there is a tray 256 that can be ejected, if confirmation print settings (not shown) are set, the process may proceed to step S9-9. In this case, regardless of the presence / absence of the tray 256 that can be ejected, the process proceeds to step S9-9 to display the message screen shown in FIG. In this case, since there is a tray 256 that can be discharged, it is possible to output if the user desires to discharge. When the confirmation print setting is made, the start key 4-241 shown in FIG. 4 can be pressed, and when the start key 4-241 is pressed, the CPU circuit unit 122 performs processing in step S9-11. Control to perform printing.

(Specific example 3)
When the continuous reading key 811 shown in FIG. 6A is pressed, it is possible to add documents. Hereinafter, an example of the document adding process will be described.

  For example, 100 out of 200 A4 size double-sided originals are stacked on the original feeder 101, A4 size recording paper is placed in the cassette 214, and a free size (297 mm × 424 mm for two A4 size recording papers +4 mm is placed on the manual feed tray 227. Set the recording paper.

  Further, when the case binding is set and the start key 4-241 is pressed in accordance with the flow of the operation procedure of FIGS. 6 and 7, the process proceeds to step S9-1 to start the process, and the document feeder 101 feeds the document. Paper and read 100 sheets by duplex scanning. That is, the total original 200 surface is read. Proceeding to step S9-2, since the number of original pages is 200, it is determined that 100 is obtained in double-sided printing.

  Since the originals can be added, the remaining 100 original A4 sizes are stacked on the original feeder 101, and when the start key 4-241 is pressed, 100 sheets are read by double-sided reading. That is, the surface of the original 200 is read. Since the total number of printed sheets is 200 and the number of original pages is 400, printing is 200 sheets, and the number of printed sheets is determined to be 200.

  Then, the process proceeds to step S9-4, and it is determined whether or not case binding. Since case binding is now performed, the process advances to step S9-5 to determine whether the number of printed sheets is equal to or greater than the minimum processable number. Since the number of prints is 200 and the minimum processable number is 10, it is determined that the process is possible, and the process proceeds to step S9-6. In step S9-6, since the number of printed sheets is 200 and the maximum processable number is 150, it is determined that the sheet cannot be ejected, and the process proceeds to step S9-8 to determine whether there is a tray that can be ejected. . Since it can be discharged to the tray 256 now, the process proceeds to step S9-12, printing is performed, and the tray 256 is discharged.

  If there is no tray that can be ejected in step S9-8, the process proceeds to step S9-9, the message screen shown in FIG. 14B is displayed, and printing is interrupted. By pressing the cancel key displayed on the message screen shown in FIG. 14B, the print job can be interrupted.

(Specific example 4)
Next, 50 double-sided originals A4 size are stacked on the original feeder 101 and A4 size recording paper is set in the cassette 214. In accordance with the flow of the operation procedure shown in FIGS. 6 and 7, when the top binding is set and the start key 4-241 is pressed, the process proceeds to step S <b> 9-1 to start processing, and the document feeder 101 starts. A document is fed and 50 sheets are scanned by double-sided scanning. That is, the total original 100 surface is read. Proceeding to step S9-2, since the number of original pages is 100, it is determined that double-sided printing results in 50 sheets, and the number of printed sheets is fixed to 50. In step S9-4, it is determined whether or not case binding is performed. In this example, since it is a sheet binding, the process proceeds to step S9-13, it is determined whether or not it is a sheet binding, and the process proceeds to step S9-14.

  In step S9-14, it is determined whether the number of printed sheets exceeds the maximum processable number. Since the number of prints is 50 and the maximum processable number is 150, it is determined that printing is possible, and the process proceeds to step S9-15 to execute printing.

(Specific example 5)
Next, for example, five double-sided originals A4 size are stacked on the original feeder 101 and A4 size recording paper is set in the cassette 214. In accordance with the flow of the operation procedure shown in FIGS. 6 and 7, when the top binding is set and the start key 4-241 is pressed, the process proceeds to step S <b> 9-1 to start processing, and the document feeder 101 starts. Feed the original and scan 5 sheets by duplex scanning. That is, the total original 10 side is read. Proceeding to step S9-2, since the number of original pages is 10, it is determined that double-sided printing results in 5 sheets, and the number of printed sheets is determined to be 5. In step S9-4, it is determined whether or not case binding is performed. In this example, since it is a sheet binding, the process proceeds to step S9-13, it is determined whether or not it is a sheet binding, and the process proceeds to step S9-14. In step S9-14, it is determined whether the number of printed sheets exceeds the maximum processable number. In this example, since the number of prints is 5 and the maximum processable number is 150, the process advances to step S9-15 to execute printing.

(Specific example 6)
When the continuous reading key 811 shown in FIG. 6A is pressed, it is possible to add documents. Hereinafter, an example of the document adding process will be described.

  For example, 100 out of 200 double-sided originals A4 size are stacked on the original feeder 101 and A4 size recording paper is set in the cassette 214.

  Further, in accordance with the flow of the operation procedure shown in FIGS. 6 and 7, when setting the sheet binding and pressing the start key 4-241, the process proceeds to step S <b> 9-1 to start the process, and the document is fed from the document feeder 101. Feed and read 100 sheets by duplex scanning. That is, the total original 200 surface is read. Proceeding to step S9-2, since the number of original pages is 200, it is determined that 100 is obtained in double-sided printing.

  Since the originals can be added, the remaining 100 original A4 sizes are stacked on the original feeder 101, and when the start key 4-241 is pressed, 100 sheets are read by double-sided reading. That is, the surface of the original 200 is read. Since the total number of printed sheets is 200 and the number of original pages is 400, printing is 200 sheets, and the number of printed sheets is determined to be 200.

  Then, the process proceeds to step S9-4, and it is determined whether or not case binding. In this example, since it is a sheet binding, the process proceeds to step S9-13, it is determined whether or not it is a sheet binding, and the process proceeds to step S9-14. In step S9-14, it is determined whether the number of printed sheets exceeds the maximum processable number. In this example, the number of printed sheets is 200, and the maximum number of sheets that can be processed is 150. Therefore, it is determined that the sheet cannot be ejected, and the process proceeds to step S9-16 to determine whether there is a tray that can be ejected. Since it can be discharged to the tray 256 now, the process proceeds to step S9-21 to perform printing, and discharges to the tray 256.

  If there is no tray that can be ejected in step S9-16, the process proceeds to step S9-17, the message screen shown in FIG. 14C is displayed, and printing is interrupted. By pressing the cancel key displayed on the message screen shown in FIG. 14C, the print job can be interrupted.

  In step S9-16, even if there is a tray 256 that can be ejected, if confirmation print settings (not shown) are made, the process may proceed to step S9-9. In this case, regardless of the presence or absence of the tray 256 that can be ejected, the process proceeds to step S9-17 to display the message screen shown in FIG. In this case, since there is a tray 256 that can be discharged, it is possible to output if the user desires to discharge. When the confirmation print setting is made, the start key 4-241 shown in FIG. 4 can be pressed, and when the start key 4-241 is pressed, the CPU circuit unit 122 performs the processing in step S9-19. Control to perform printing.

  As described above, the CPU circuit unit 122 restricts the number of sheets to be processed when the operation flow shown in FIGS. 6 and 7 specifies and selects only the paper size that can be bound and then starts the operation. If they do not match, a failure such as a paper jam occurs, and the number of output sheets is determined, so reading is prioritized.

  Then, when the number of read sheets is determined, it is determined whether or not processing is possible. Note that the case binding shown in FIG. 8 (a) requires the operation of bringing the cover into close contact with the inner sheet (text), so that a certain amount of thickness is required for the inner sheet bundle. Occurs, and a limit value of the minimum processable number is generated. On the other hand, in the case binding with no cover shown in FIG. 8B, there is no need for the operation of bringing the cover into close contact with the inner sheet, so the limit value of the minimum processable number does not occur. For this reason, the CPU circuit unit 122 determines the type of bookbinding that has been designated, and performs control so that the minimum number of sheets that can be processed is not determined in the case of sheet binding.

  Further, although the device size is reduced, the maximum number of sheets that can be processed is limited. However, the CPU circuit unit 122 determines the maximum number of sheets that can be processed in both the case binding and the top binding.

  Then, the CPU circuit unit 122 performs control so that the operation is interrupted when the limit number of sheets is exceeded based on each determination result corresponding to the glue binding type, or the output is performed by a method that does not use the bookbinding function, Similarly, when the number of sheets is less than the limit number, the operation is interrupted, or the output is controlled by a method that does not use the bookbinding function.

  As described above, the CPU circuit unit 122 can control the gluing bookbinding machine having a smaller device size without causing a failure by performing control suitable for the restriction, resulting in cost and installation. Even if there is a problem in area, it can be introduced, and glue binding can be performed without cost.

  Further, in the case of a top-bound bookbinding without a cover, since the minimum number of sheets that can be processed is not limited, it can be used as a simple bookbinding.

  Accordingly, it is possible to perform control corresponding to the restriction generated by reducing the size of the glue binding apparatus, and a user who does not know the maximum processable number and the minimum processable number of the glue binding apparatus can set the limit number. It is possible to prevent the occurrence of a bookbinding failure due to printing and bookbinding exceeding the number of sheets.

[Second Embodiment]
In the first embodiment, the case has been described in which the minimum processable number and the maximum processable number are each one value regardless of the type of paper to be printed. However, the minimum number of sheets that can be processed depends on the type of paper to be printed. The maximum processable number of sheets may be changed. The embodiment will be described below.

  Hereinafter, the case binding and top glue binding control in the present embodiment will be described with reference to FIG.

  FIG. 15 is a flowchart showing an example of a second control processing procedure in the image forming apparatus of the present invention. The processing of this flowchart is realized by the CPU circuit unit 122 shown in FIG. 2 loading a program stored in the ROM 124 or a hard disk in the image memory 120 or another storage medium (not shown) into the RAM 125 and executing it. In the figure, S9-1 to S9-22, S10-1, and S10-2 indicate steps, and the same steps as those in FIG. 13 are denoted by the same step numbers, and the description thereof is omitted. In this embodiment, for example, the minimum processable sheet number is 10 and the maximum processable sheet number is 150 sheets. If the recording paper is a thick sheet, the minimum processable sheet number is changed to 5 sheets and the maximum processable sheet number is changed to 75 sheets. It shall be.

  When the number of printed sheets is determined in step S9-3, in step S10-1, the CPU circuit unit 122 determines whether or not the recording paper is thick paper. Proceed to S9-4.

  On the other hand, if the CPU circuit unit 122 determines in step S10-1 that the recording sheet is a thick sheet, the process proceeds to step S10-2, where the maximum processable sheet number is changed from 150 sheets to 75 sheets, and the minimum number is further reduced. The number of processable sheets is changed from 10 to 5, and the process proceeds to step S9-4.

  The paper type is determined based on the paper feed stage setting information stored in a nonvolatile memory (not shown) in the RAM 125 and the paper feed stage selected in the job. It is assumed that the CPU circuit unit 122 determines.

  Hereinafter, an example is given and it demonstrates more concretely.

(Specific example 1)
For example, 50 A4 size double-sided originals are stacked on the original feeder 101, A4 size thick recording paper is placed in the cassette 214, and a free size (297 mm x 424 mm A4 size recording paper + 4 mm back on the manual feed tray 227 ). Then, in accordance with the operation flow shown in FIGS. 6 and 7, the case binding is set, and the start key 4-241 is pressed. Then, the process is started (S9-1), a document is fed from the document feeder 101, and 50 sheets are read by double-sided scanning (S9-2). That is, the total original 100 surface is read.

  In step S9-3, since the number of original pages is 100, it is determined that double-sided printing results in 50 sheets, and the number of printed sheets is determined to be “50”.

  Next, the paper type of the recording paper is determined. In step S10-1, it is determined whether the recording paper is a thick paper. Since this example is thick paper, the minimum processable number of sheets is changed to 5 and the maximum processable number of sheets is changed to 75 in step S10-2, and the process proceeds to step S9-4.

  Next, in step S9-4, it is determined that it is case binding and the process proceeds to step S9-5. In this example, the number of prints is 50, and the minimum processable number is 5. Therefore, it is determined that the number of prints is equal to or greater than the minimum processable number, and the process proceeds to step S9-6. In this example, the number of prints is 50, and the maximum processable number is 75. Therefore, in step S9-6, it is determined that the number of prints does not exceed the maximum processable number, and the process proceeds to step S9-7. Then, printing is performed, case binding is performed, and the process is terminated (S-922).

(Specific example 2)
Next, 5 double-sided originals A4 size are stacked on the original feeder 101, A4 size cardboard recording paper is loaded in the cassette 214, and a free size (297 mm × 424 mm for two A4 size recording papers + 4 mm on the manual feed tray 227). An example of setting the recording paper of the back portion will be described.

  When the case binding is set and the start key 4-241 is pressed in accordance with the flow of the operation procedure shown in FIGS. 6 and 7, the process proceeds to step S9-1, and the process is started. A document is fed from the feeding device 101 and three sheets are read by double-sided reading. That is, the total original 6 side is read. Proceeding to step S9-3, since the number of original pages is 6, it is determined that the double-sided printing is 3, and the number of prints is fixed to "3".

  Next, the paper type of the recording paper is determined. In step S10-1, it is determined whether the recording paper is a thick paper. Since this example is thick paper, the minimum processable number of sheets is changed to 5 and the maximum processable number of sheets is changed to 75 in step S10-2, and the process proceeds to step S9-4.

  In step S9-4, it is determined whether it is case binding. In this example, since case binding is performed, the process advances to step S9-5 to determine whether the number of printed sheets is equal to or greater than the minimum processable number. In this example, since the number of printed sheets is 3 and the minimum processable number is 5, it is determined that 3 printed sheets are not 5 or more and cannot be processed, and the process proceeds to step S9-8.

  Next, in step S9-8, it is determined whether there is a tray that can be ejected. If it can be discharged to the tray 256 shown in FIG. 1, the process proceeds to step S9-12 to perform printing (but without case binding), and discharges to the tray 256.

  On the other hand, if there is no tray that can be ejected in step S9-8, the process proceeds to step S9-9 to display the message screen shown in FIG. The user can cancel the print job by pressing the cancel key displayed in FIG.

  In step S9-8, even if there is a tray 256 that can be ejected, if confirmation print settings (not shown) are set, the process may proceed to step S9-9. In this case, regardless of whether or not there is a tray 256 that can be ejected, the process proceeds to step S9-9 to display the message screen shown in FIG. In this case, since there is a tray 256 that can be discharged, it is possible to output if the user desires to discharge. When the confirmation print setting is made, the start key 4-241 shown in FIG. 4 can be pressed, and when the start key 4-241 is pressed, the CPU circuit unit 122 performs processing in step S9-11. Control to perform printing.

Is fed and 100 sheets are read by double-sided scanning. That is, the total original 200 side is read. Proceeding to step S9-2, since the number of original pages is 200, it is determined that double-sided printing will be 100. In step S9-3, the number of prints is fixed to "100".

  Next, the paper type of the recording paper is determined. In step S10-1, it is determined whether the recording paper is a thick paper. Since this example is thick paper, the minimum processable number of sheets is changed to 5 and the maximum processable number of sheets is changed to 75 in step S10-2, and the process proceeds to step S9-4.

  In step S9-4, it is determined whether it is case binding. In this example, since case binding is performed, the process advances to step S9-5 to determine whether the number of printed sheets is equal to or greater than the minimum processable number. In this example, the number of prints is 100 and the minimum processable number is 5. Therefore, it is determined that the number of prints is equal to or greater than the minimum processable number, and the process proceeds to step S9-6. In this example, the number of prints is 100, and the maximum number of sheets that can be processed is 75. Therefore, in step S9-6, the number of prints exceeds the maximum number of sheets that can be processed, and it is determined that the process cannot be performed. Proceed to -8.

  Next, in step S9-8, it is determined whether there is a tray that can be ejected. If it can be discharged to the tray 256 shown in FIG. 1, the process proceeds to step S9-12 to perform printing (but without case binding), and discharges to the tray 256.

  On the other hand, if there is no tray that can be ejected in step S9-8, the process proceeds to step S9-9 to display the message screen shown in FIG. The user can cancel the print job by pressing the cancel key displayed in FIG.

  In step S9-8, even if there is a tray 256 that can be ejected, if confirmation print settings (not shown) are set, the process may proceed to step S9-9. In this case, regardless of the presence / absence of the tray 256 that can be ejected, the process proceeds to step S9-9 to display the message screen shown in FIG. In this case, since there is a tray 256 that can be discharged, it is possible to output if the user desires to discharge. When the confirmation print setting is made, the start key 4-241 shown in FIG. 4 can be pressed, and when the start key 4-241 is pressed, the CPU circuit unit 122 performs processing in step S9-11. Control to perform printing.

(Specific example 4)
Next, 50 A4 size double-sided originals are stacked on the original feeder 101, and A4 size thick recording paper is set in the cassette 214. In accordance with the flow of the operation procedure shown in FIG. 6 and FIG. 7, when the top binding is set and the start key 4-241 is pressed, the process proceeds to step S9-1 to start the processing. In step S9-2, A document is fed from the document feeder 101 and 50 sheets are read by duplex scanning. That is, the total original 100 surface is read. Proceeding to step S9-3, since there are 100 original pages, it is determined that double-sided printing will result in 50 sheets, and the number of printed sheets is fixed to 50.

  Next, the paper type of the recording paper is determined. In step S10-1, it is determined whether the recording paper is a thick paper. Since this example is thick paper, the minimum processable number of sheets is changed to 5 and the maximum processable number of sheets is changed to 75 in step S10-2, and the process proceeds to step S9-4.

  Next, in step S9-4, it is determined whether it is case binding. In this example, since it is a sheet binding, the process proceeds to step S9-13, it is determined whether or not it is a sheet binding, and the process proceeds to step S9-14.

  In step S9-14, it is determined whether the number of printed sheets exceeds the maximum processable number. Since the number of prints is 50 and the maximum processable number is 75, it is determined that printing is possible, and the process proceeds to step S9-15 to execute printing.

(Specific example 5)
Next, for example, three double-sided originals A4 size are stacked on the original feeder 101, and A4 size thick recording paper is set in the cassette 214. In accordance with the flow of the operation procedure shown in FIG. 6 and FIG. 7, when the top binding is set and the start key 4-241 is pressed, the process proceeds to step S9-1 to start the processing. In step S9-2, A document is fed from the document feeder 101 and three sheets are read by duplex scanning. That is, the total document 6 side is read. Proceeding to step S9-3, since the number of original pages is 6, it is determined that the number of printed sheets is 3 in double-sided printing, and the number of printed sheets is determined to be 3.

  Next, the paper type of the recording paper is determined. In step S10-1, it is determined whether the recording paper is a thick paper. Since this example is thick paper, the minimum processable number of sheets is changed to 5 and the maximum processable number of sheets is changed to 75 in step S10-2, and the process proceeds to step S9-4.

  Next, in step S9-4, it is determined whether it is case binding. In this example, since it is a sheet binding, the process proceeds to step S9-13, it is determined whether or not it is a sheet binding, and the process proceeds to step S9-14. In step S9-14, it is determined whether the number of printed sheets exceeds the maximum processable number. In this example, the number of prints is 3, and the maximum processable number is 75, so the process proceeds to step S9-15 to execute printing.

(Specific example 6)
Next, for example, 100 double-sided original A4 size sheets are stacked on the original feeding apparatus 101, and A4 size thick recording paper is set in the cassette 214. In accordance with the flow of the operation procedure shown in FIG. 6 and FIG. 7, when the top binding is set and the start key 4-241 is pressed, the process proceeds to step S9-1 to start the processing. In step S9-2, A document is fed from the document feeder 101 and 100 sheets are read by duplex scanning. That is, the total original 200 surface is read. Proceeding to step S9-3, since the number of original pages is 200, it is determined that double-sided printing results in 100 sheets, and the number of printed sheets is fixed to 100.

  Next, the paper type of the recording paper is determined. In step S10-1, it is determined whether the recording paper is a thick paper. Since this example is thick paper, the minimum processable number of sheets is changed to 5 and the maximum processable number of sheets is changed to 75 in step S10-2, and the process proceeds to step S9-4.

  Next, in step S9-4, it is determined whether it is case binding. In this example, since it is a sheet binding, the process proceeds to step S9-13, it is determined whether or not it is a sheet binding, and the process proceeds to step S9-14. In step S9-14, it is determined whether the number of printed sheets exceeds the maximum processable number. In this example, since the number of printed sheets is 100 and the maximum processable number is 75, it is determined that the sheet cannot be discharged, and the process proceeds to step S9-16 to determine whether there is a tray that can be discharged. Since it can be discharged to the tray 256 now, the process proceeds to step S9-21 to perform printing, and discharges to the tray 256.

  If there is no tray that can be ejected in step S9-16, the process proceeds to step S9-17, the message screen shown in FIG. 14C is displayed, and printing is interrupted. By pressing the cancel key displayed on the message screen shown in FIG. 14C, the print job can be interrupted.

  In step S9-16, even if there is a tray 256 that can be ejected, if confirmation print settings (not shown) are made, the process may proceed to step S9-9. In this case, regardless of the presence or absence of the tray 256 that can be ejected, the process proceeds to step S9-17 to display the message screen shown in FIG. In this case, since there is a tray 256 that can be discharged, it is possible to output if the user desires to discharge. When the confirmation print setting is made, the start key 4-241 shown in FIG. 4 can be pressed, and when the start key 4-241 is pressed, the CPU circuit unit 122 performs the processing in step S9-19. Control to perform printing.

  In the above-described embodiment, the configuration has been described in which the minimum processable sheet number and the maximum processable sheet number are changed only when the paper type is thick paper. However, a plurality of paper types (which are classified according to the paper thickness and the like) are described. The minimum number of sheets that can be processed and the maximum number of sheets that can be processed may be changed according to a plurality of paper types).

  As described above, the CPU circuit unit 122 changes and controls the restriction conditions (minimum number of sheets that can be processed, maximum number of sheets that can be processed) depending on the paper type. It can be avoided.

  Therefore, it is possible to prevent the occurrence of a bookbinding failure caused by a user who does not know the maximum number of sheets that can be processed and the maximum number of sheets that can be processed depending on the paper type, trying to print and book a number of sheets exceeding the limit number. Can do.

[Third Embodiment]
In the first and second embodiments, the configuration has been described in which print processing is simply performed without performing case binding when case binding cannot be performed due to the number of prints being less than the minimum processable number. When bookbinding cannot be performed due to the number of sheets being less than the minimum processable number of sheets, it may be configured to perform book binding. The embodiment will be described below.

  Hereinafter, the case binding and the top glue binding control in this embodiment will be described with reference to FIGS.

  FIG. 16 is a flowchart showing an example of a third control processing procedure in the image forming apparatus of the present invention. The processing of this flowchart is realized by the CPU circuit unit 122 shown in FIG. 2 loading a program stored in the ROM 124 or a hard disk in the image memory 120 or another storage medium (not shown) into the RAM 125 and executing it. Note that S9-1 to S9-22, S12-1, and S12-2 in the figure indicate the respective steps, and the same steps as those in FIG. In this embodiment, for example, the minimum processable number of sheets is 10 and the maximum processable number of sheets is 150.

  In step S9-4, it is determined that case binding is set, and the process proceeds to step S9-5. If the CPU circuit unit 122 determines that the case printing process is not possible because the number of printed sheets is not greater than the minimum processable number. In step S12-1, the message screen shown in FIG. 17 is displayed on the liquid crystal display unit 4-250, control is performed so as to interrupt printing, and the process proceeds to step S12-2.

  FIG. 17 is a schematic diagram showing an example of a message screen displayed when case binding cannot be performed due to the number of printed sheets being less than the minimum processable number in the image forming apparatus of the present invention.

  In FIG. 17, reference numeral 1101 denotes a cancel key. By pressing this key, the print job can be canceled. Further, when the start key 4-241 shown in FIG. 4 is pressed while the message screen of FIG. 17 is displayed, case binding is executed by changing to case binding.

  Hereinafter, the description returns to the flowchart of FIG.

  In step S12-2, the CPU circuit unit 122 determines whether or not there is a change to the paste binding depending on whether or not the start key 4-241 is pressed while the message screen of FIG. 17 is displayed. If it is determined that the start key 4-241 has been pressed while the message screen is displayed, the screen is changed to a sheet binding and the process proceeds to step S9-14.

  On the other hand, if the CPU circuit unit 122 determines in step S12-2 that the start key 4-241 has not been pressed while the message screen of FIG. 17 is displayed, the CPU circuit unit 122 changes to the sheet binding. Without performing, the process proceeds to step S9-8.

  Hereinafter, an example is given and it demonstrates more concretely.

(Concrete example)
For example, five A4 size double-sided originals are stacked on the original feeder 101, A4 size thick recording paper is loaded in the cassette 214, and a free size (297 mm × 424 mm, two A4 size recording sheets +4 mm back on the manual feed tray 227 ). Then, in accordance with the operation flow shown in FIGS. 6 and 7, the case binding is set, and the start key 4-241 is pressed. Then, the process is started (S9-1), a document is fed from the document feeder 101, and five sheets are read by double-sided scanning (S9-2). That is, the total original 10 side is read.

  In step S9-3, since the number of original pages is 10, it is determined that double-sided printing results in 5 sheets, and the number of printed sheets is determined to be “5”.

  Next, in step S9-4, it is determined that it is case binding and the process proceeds to step S9-5. In this example, the number of prints is 5 and the minimum processable number is 10. Therefore, the number of prints is equal to or less than the minimum processable number, so it is determined that case binding processing is impossible, and step S12-1 is performed. The message screen shown in FIG. 17 is displayed and printing is interrupted.

  Next, it is determined whether or not to transfer to the book binding. When the CPU circuit unit 122 detects that the user has pressed the start key 4-241 while the message screen shown in FIG. 17 is displayed, the CPU circuit unit 122 determines to transfer to the top binding. To do.

  If it is determined in step S12-2 that the transfer is to be made to the book binding, the process proceeds to step S9-14, and it is determined whether the number of printed sheets does not exceed the maximum processing number. In this example, since the number of printed sheets is 100 and the maximum number of sheets that can be processed is 150, it is determined that the sheet can be ejected, and the process advances to step S9-15 to print the inner sheet and perform the glue binding.

  On the other hand, if it is determined in step S12-2 that the booklet is not changed to the sheet binding, the process proceeds to step S9-8 to determine whether there is a tray that can be ejected. Since it can be discharged to the tray 256 now, the process proceeds to step S9-12, printing is performed, and the tray 256 is discharged.

  If there is no tray that can be ejected in step S9-8, the process proceeds to step S9-9, the message screen shown in FIG. 14B is displayed, and printing is interrupted. By pressing the cancel key displayed on the message screen shown in FIG. 14B, the print job can be interrupted.

  In the flowchart of FIG. 16, in step S9-5, since the minimum number of printable sheets is less than 10, the process proceeds to step S12-1 when it is determined that case binding processing is impossible. The configuration in which the message screen shown in FIG. 17 is displayed to enable switching to the book binding is described. However, the setting is switched in advance from a setting screen (not shown) (setting to transfer to the book binding when case binding cannot be performed). And stored in the RAM 125. In step S9-5, the minimum number of printable sheets is less than 10, so it is determined that case binding processing is impossible, and the above switching setting is set. The process proceeds to step S12-1 only if it has been made, and on the other hand, if the switching setting has not been made, the process may proceed to step S9-8. There.

  As described above, since the CPU circuit unit 122 performs control so that the case binding cannot be selected, the sheet binding can be selected, so that the image once read can be validated as it is.

  In each of the above-described embodiments, the description has been made regarding the setting for performing double-sided document reading in the document feeder 101 and duplex printing in the printer unit 2, but document scanning and intermediate sheet printing are not limited to this, and single-sided scanning, Needless to say, single-sided printing or the like may be used.

  In each of the above embodiments, the case where the printer unit (printer engine) 2 is a laser beam method has been described as an example. However, an electrophotographic method (for example, an LED method) other than the laser beam method may also be used as a liquid crystal shutter method, an ink jet method. The present invention is applicable to any printing method, thermal transfer method, sublimation method, and other printing methods.

  Moreover, all the structures which combined the said 1st Embodiment-3rd Embodiment are also contained in this invention. For example, the control (S10-1, S10-2 in FIG. 15) for changing the maximum processable number and the minimum processable number according to the paper type of the recording sheet shown in the second embodiment, and the third embodiment. In addition, since it is less than the minimum number of sheets that can be processed, it may be configured to have control (S12-1, S12-2 in FIG. 15) for switching to book binding when case binding is impossible.

  As described above, each embodiment has been described. However, the present invention can take an embodiment as a system, apparatus, method, program, storage medium, or the like, and specifically includes a plurality of devices. The present invention may be applied to a system including a single device. In the image forming system 1000 of this embodiment, all the units other than the sheet processing apparatus 230 are inside the image forming apparatus main body (the reader unit 1 and the printer unit 2 except for the sheet processing apparatus 230 in FIG. 1). Built in. That is, the main units such as the CPU circuit unit 122 and the image memory 120 are all provided on the image forming apparatus main body side. Further, the sheet processing apparatus 230 is configured to be detachable from the image forming apparatus main body, and a sheet processing apparatus other than the sheet processing apparatus 230 can be connected. Thus, the present invention based on this embodiment is also an invention as an image forming apparatus.
