[Control flow]
A bookbinding process performed by the image forming system will be described with reference to FIGS. FIG. 6 is a diagram for explaining a control flow performed jointly by the control unit A10 and the control unit B10 of the image forming system according to the embodiment. FIG. 7 is an example of a setting screen displayed on the operation display unit 9. 8 corresponds to FIG. 15, and FIG. 9 corresponds to FIG.

  In the flow shown in FIG. 6, the reading of the original paper and the image formation on the output paper are all performed on one side, and the number of sheets and the number of pages are the same. The insertion position (Ci) of the belt-like surplus portion 92 is set in units of paper. However, when reading the original paper and forming an image on the paper on both sides, the value of the insertion position (Ci) is set to By converting the number of pages formed on the paper at the insertion position, the following flow can be applied without any problem. Further, in the following flow, the acquisition of the image data is performed by reading the document by the scanner 7, but the present invention is not limited to this, and the printing is performed based on the image data and the print job received via the network. There may be.

  In step S10, the insertion position (Ci) of the belt-like surplus portion 92 is acquired. FIG. 7 is an example of a setting screen displayed on the operation display unit 9. When the user inputs the setting information to the operation display unit 9, the setting information of the position of the belt-like surplus portion is acquired on the control unit B10 side. In the example of the setting screen illustrated in FIG. 7, the user can perform “next to cover” or “input number” by selecting either button b1 or button b2. When “next to cover” is selected by the button b2, the position of the band surplus portion 92 is set between the cover and the next sheet. When “number of sheets input” is selected, an arbitrary numerical value can be set in the field b3 by inputting with a numeric keypad. In the example shown in the figure, the insertion position (Ci) is set to the third sheet, and the belt-like surplus portion 92 is set to be inserted between the third and fourth sheets. (See FIG. 8A). After the setting is completed, the user confirms the setting by pressing the OK button, and the setting information of the insertion position is sent to the control unit A10. The control unit A10 stores the setting information in the storage unit A11.

  Steps S21 to S29 are flows relating to printing. In step S21, the variable i is initialized, and in S22, the increment is performed.

  In step S23, the scanner 7 reads the i-th page of the document set on the document table of the automatic document feeder ADF, and acquires this as image data of the i-th page. The acquired image data is temporarily stored in the storage unit A11.

  In step S25, it is determined whether or not the page i of the read original is after the insertion position (Ci). If i> Ci is not satisfied (step S25: No), the process proceeds to step S26, and the image data for the i-th page is not printed and is suspended. On the other hand, if i> Ci (step S25: Yes), in step S27, printing is performed on a sheet based on the image data of the i-th page.

  If reading by the scanner 7 has not been completed (step S27: No), the flow after step S22 is repeated. On the other hand, when reading is completed (step S27: Yes), that is, when reading of the original of the last page n is completed, in step S29, printing is suspended in step S26 from the first page to the insertion position Ci. Print image data up to the corresponding page.

  FIG. 8B shows an example in which the printing order is changed by the flow from step S21 to S29 in FIG. Since the insertion position (Ci) is the third sheet, printing starts from the image data of the page immediately after the insertion position (Ci), that is, the image data of the fourth page. Then, printing is performed up to the final nth page of image data. Thereafter, printing is performed from the first page to the third page of image data, which is image data immediately before the insertion position.

  In the stack section of the ring binding section 210, the printed sheets are in the order as shown in FIG. 8C, the sheet on which the first fourth page image is printed is the bottom layer, and the top layer is the third page image. Is placed so that it becomes a paper on which is printed. In this loaded state, the image forming surface is on the lower side of the sheet if it is one side. In step S40 of FIG. 6, the ring bookbinding unit 210 executes the bookbinding process for the sheet bundle in such a state, and the process ends.

  FIG. 9 shows a booklet bk created by the control flow of FIG. As shown in FIG. 9A, in the booklet bk immediately after creation, the belt-like surplus portion 92 is positioned on the third sheet S. The user can turn the sheets before the boundary between the nth sheet and the first sheet (the first sheet to the third sheet) and turn them over to make the state shown in FIG. 9B.

  In the example shown in FIG. 15, the insertion position of the belt-like surplus portion 92 is fixed to the (n−1) th sheet, and the first printing cannot be started until all the originals have been read. On the other hand, in this embodiment, the insertion position can be set to an arbitrary position. Further, depending on the setting, the first printing can be started when reading of the next document at the insertion position is completed before reading of all the documents is completed. As a result, the start of printing can be made earlier, and as a result, productivity can be improved.

[Second Embodiment]
FIG. 10 is a diagram for explaining a control flow performed jointly by the control unit A10 and the control unit B10 of the image forming system according to the second embodiment. In the example shown in the figure, a partition sheet is inserted. In the control flow shown in the figure, the control is the same as that in FIG. 6 except for steps S31 and S32.

  The setting for inserting the partition sheet is performed on the setting screen shown in FIG. By selecting the button b4 in the figure, the insertion of the partition sheet can be validated (present). If “valid” is selected in b4, it is possible to further set the paper feed tray to be used in the b5 column. As the paper feed tray to be used, paper feed trays such as the insertion paper trays 52a, 51a, 51b, and 51c and the paper feed / conveying unit 5a of the image forming apparatus A may be used. After the setting is completed, the user confirms the setting by pressing the OK button, and the setting information of the insertion position is sent to the control unit A10. The control unit A10 stores the setting information in the storage unit A11.

  The same control as in FIG. 6 is performed from step S21 to step S28, and the partition paper is conveyed to the stack portion of the ring binding unit 210 in step S32. FIG. 11 is a diagram illustrating a stacking state of the sheet bundle in the stack unit of the ring bookbinding unit 210. In the stack unit, sheets on which image data up to the final nth page are printed are stacked, and then sheets on which image data on the first and subsequent pages are printed in step S29. As shown in FIG. 11, the partition sheet TS is inserted between the nth page and the first page.

  The partition paper is preferably different in color and size so that it can be easily distinguished from other papers forming the booklet bk, but is not limited to this, and is the same size and type as the paper S forming the booklet bk. The paper may be used. Since it becomes unnecessary after the turning process as the partition paper, it is preferable to use a paper that can be removed thereafter. For example, a thin paper can be removed after use by being torn by the user, or a paper that is not punched is used to move the stack at the stack part of the ring bookbinding unit 210 and stack it after use. It can be made possible.

  FIG. 12 is a diagram illustrating a control flow according to a modification. This figure is a control flow executed subsequent to step S40 in FIG. 6 or FIG. 10.
