Description

  The present invention relates to a printing apparatus, a printing apparatus control method, and a program.

  A conventional printing apparatus has a function of inserting an index sheet (also referred to as a tab sheet) for the purpose of clarifying a chapter or section heading of a printed matter. Normally, index paper is stored in a paper feed stage in units of a set with a certain number of divisions. For this reason, it is necessary to perform “cueing” in which excess index sheets are discharged out of the apparatus to a discharge tray different from the discharge tray for the printed matter of the main body at the break of the job or the cut of the copy.

In addition, there is a type in which a plurality of types of index sheets are inserted into the printed material of the main body in a consistent order (for example, see Patent Document 1).
For example, it is a case where the visibility of chapters and sections is improved by inserting a plurality of index sheets having different colors into the printed material as in the product 300 shown in FIG. Here, an example is assumed in which three types of six-divided sets of index paper sets 1001, 1002, and 1003 are inserted in a consistent order when stored in the respective paper feed cassettes. For the text 1010, the first type of index paper is inserted into the first division (index paper 1004) and the second division (index paper 1005).
Next, for the second type of index paper, the third division (index paper 1006) and the fourth division (index paper 1007) are inserted. Finally, for the third type of index paper, the fifth division (index paper 1008) and the sixth division (index paper 1009) are inserted.
As a result, a product 300 in which a plurality of types of index sheets are inserted in a consistent order is obtained. However, the surplus index sheets 1011, 1012, and 1013 when the index sheets are inserted in a consistent order are generated at the stage where the index sheets are inserted into the text.

JP 2006-248672 A

  When a plurality of types of index sheets are inserted in a consistent order with respect to the printed material of the main text, when the first type of index sheets 2001 are inserted as shown in FIG. 14, the other second and third types of index sheets are inserted. Index sheets 2003 and 2004 at the same division position are not necessary. Therefore, a large amount of surplus index paper may be generated for each copy. At this time, when the user reuses the surplus index sheet bundle 402 discharged outside the apparatus, the surplus index sheets need to be rearranged and reconfigured.

  However, when a plurality of index sheets are inserted in a consistent order as shown in the surplus index sheet discharge order 403 in FIG. 14, each time an index sheet is inserted, the index sheets at the same division position other than the inserted index sheet are inserted. Need to be discharged from the machine. For this reason, the surplus index sheets are discharged outside the apparatus in the order in which the types are output separately. In particular, if the number of output trays is limited, even if the output trays are separated for each type of surplus index paper, multiple types of index paper can be output to the same output tray. I must. Therefore, it is very troublesome for the user to rearrange and reconfigure the surplus index sheet bundle 402.

The present invention has been made to solve the above-described problems, and an object of the present invention is to discharge paper so that the positions of excess index sheets are continuously aligned in the process of inserting different types of index sheets. It is to provide a mechanism.

The printing apparatus of the present invention that achieves the above object has the following configuration.
A plurality of sheet feeding units that feed different types of index sheets that form a set of a plurality of sheets, and a plurality of index sheets having different tab positions from each sheet feeding unit are sequentially selected and inserted between the printed materials. As described above, when switching to each sheet feeding unit, and when switching to the subsequent sheet feeding unit, the tab position of the index sheet last fed from the previously selected sheet feeding unit, and the sheet feeding selected next. Index sheets that are not used by the following paper feeding means and that have different tab positions are continuously placed at specific discharge destinations so that the tab positions of the index papers to be fed from the paper means are continuous in one set. And a paper discharge means for discharging the paper.

  According to the present invention, sheets can be discharged so that the positions of the index sheets that are excessive in the process of inserting different types of index sheets are continuously aligned.

  An OK key 1201 shown in FIG. 8 is a soft key for saving the insertion sheet setting set in the insertion sheet position list 10010 to the storage device 207 and reflecting it in the copy job. Complete. The contents set using the operation screens of FIGS. 3 to 10 are stored in the storage device 207 and referred to by the CPU 201.

  FIG. 10 is a flowchart for explaining a control method of the printing apparatus according to the present embodiment. This example is a print processing example when the continuous index sheet mode is designated. Each step is realized by the CPU 201 loading a control program stored in the ROM 205 or the storage device 207 into the RAM 202 and executing it.

  In S100, when the CPU 201 detects that the user has pressed the start key 706 of the operation unit 102, a copy job set to insert an insertion sheet in the continuous index sheet mode is started. In step S <b> 101, the CPU 201 sequentially reads the originals placed on the reader unit 101, thereby writing the image data read by the image sensor (CIS) into the storage device 207, which is read out at a predetermined timing and sent to the printer unit 108. send. In S102, the CPU 201 secures a counter area for the total number of index sheets and the number of sheets for each index sheet type in the storage device 207 and initializes them with “0”.

  In step S <b> 103, the CPU 201 reads an insertion sheet setting stored in the storage device 207, thereby writing a sheet feeding stage for feeding an insertion sheet to be inserted at the beginning of the job in the storage area of the storage device 207. Here, the information to be written in the storage area is a paper feed stage, but may be a paper type, a paper size, etc. as long as the type of index paper can be uniquely determined. Next, in S104, the CPU 201 sequentially reads out the image data of the original read in S101 from the storage device 207, and starts the printing process according to the insertion sheet setting.

  In step S105, the CPU 201 reads the insertion sheet setting from the storage device 207, and determines whether the sheet type of the next page to be processed is an index sheet. If the CPU 201 determines that the sheet is an index sheet in S105, the process proceeds to S106. If the CPU 201 determines that the sheet is not an index sheet, the process proceeds to S111 and the printing process is continued.

In step S106, the CPU 201 reads the storage area written in the storage device 207 in step S103, and determines whether or not the sheet feeding stage is the same as the sheet feeding stage of the index sheet to be currently fed. If the CPU 201 determines that the paper feed stages are different as a result of the comparison in step S106, the process proceeds to step S107. If the CPU 201 determines that the paper feed stages are the same, the process advances to step S111, and the index paper is fed and printed. Process.
In step S <b> 107, the CPU 201 determines whether or not it is necessary to discharge the surplus index sheets for the index sheet feeding stage to be currently fed. Here, the CPU 201 subtracts the number B of the index sheets to be currently fed from the total number A of the index sheets inserted in the job to determine whether or not the surplus index sheets need to be discharged. Judge by value. That is, if the CPU 201 determines that (A−B) = 0, it is determined that there is no need to discharge surplus index sheets, and the process proceeds to S109.
On the other hand, when the CPU 201 determines that the relationship of (A−B)> 0 is established, the process proceeds to S108, and the CPU 201 sets (A−B) sheets as surplus index sheets from the sheet feeding stage to be currently fed. Paper is discharged to a paper discharge tray that is different from the paper discharge tray that outputs the text.

  In step S109, the CPU 201 overwrites the storage area written in the storage device 207 in step S103 with the index sheet supply stage that the CPU 201 is currently supplying. Next, in S110, the CPU 201 increments the counter area of the total number of index sheets fed in S102 and the number of index sheets to be fed now by “1”.

In step S111, the CPU 201 feeds a sheet of a page to be processed currently including an index sheet from a sheet feeding stage, sends it to a printer unit, performs a printing process, and discharges the sheet. In step S <b> 112, the CPU 201 determines whether or not the insertion sheet is not fed from the sheet feeding stage stored in the storage device 207 thereafter in the job. Note that the CPU 201 determines whether or not to supply paper by reading out the insertion paper setting from the storage device 207 and determining whether or not paper supply occurs from the paper supply stages stored after the current processing page. Here, when the CPU 201 determines that the sheet feeding from the stored sheet feeding stage occurs, the process proceeds to S113, and the surplus index sheet discharging process is performed.
In step S113, the CPU 201 reads the setting of the insertion sheet from the storage device 207, and obtains a value (P−B) that is obtained by subtracting the number of sheets B of the index sheet type stored in the sheet feeding stage from the number P of index sheet divisions. It is discharged from the machine as surplus index paper.

  On the other hand, if the CPU 201 determines that the paper feed from the paper feed stage stored in S112 does not occur, or if the surplus index paper discharge is finished in S113, the process proceeds to S114. In step S114, the CPU 201 determines whether or not the printing process for the job has been completed. If it is determined that the printing process has not been completed, the process returns to step S105.

  Note that the processing example of FIG. 10 is also effective when the number of copies is set to a plurality of copies. Here, a case will be described with reference to FIGS. 11 and 12 in which three types of 6-divided sets of index sheets are set to be inserted into the text two by two and output according to the processing flow of FIG. 10 in the present embodiment.

In the index sheet setting state shown in FIG. 11, 5001, 5002, and 5003 indicate that the three types of index sheets are set in the cassette sheet feeding stages 1, 2, and 3, respectively. The cassette paper feed stages 1, 2, and 3 correspond to any of the cassette paper feed stages 103A, 103B, and 103C included in the cassette paper feed stage 130 shown in FIG.
The continuous index sheet mode is set from the operation unit 102, and the index sheet of the cassette paper feed stage 1 is designated on the first page and the fourth page. The index paper of the cassette paper feed stage 2 is designated on the 7th and 10th pages.

The index paper of the cassette paper feed stage 3 is designated on the 13th and 16th pages. The discharge order of the text, the insertion sheet, and the surplus index sheet when the insertion sheet setting is performed as described above is shown as a discharge order 600 shown in FIG. FIG. 12A shows a first paper discharge control example. Specifically, before switching to the subsequent paper feeding unit, the same type of index paper that is not used from the tab position of the index paper last fed from the previously selected paper feeding unit is continuously specified. This is an example of discharging paper continuously discharged to the paper tip.
Here, in the paper discharge order 600 shown in FIG. 12A, the halftone square indicates the index paper 5001 in the cassette paper feed stage 1, and the hatched square indicates the index paper 5002 in the cassette paper feed stage 2. A shaded square represents the index paper 5003 in the cassette paper feed stage 3.

The numbers in the squares indicate the index division positions. In addition, a change in the storage area in which the paper feed stage is stored in the storage device 207 in S103 illustrated in FIG.
In the paper discharge order 600 shown in FIG. 12A, the index paper of the cassette paper feed stage 1 is inserted into the first page (index paper 6001) and the fourth page (index paper 6002) according to the insertion paper setting (S100-). S114).
At the stage when the index paper 6002 of the fourth page is inserted, no additional paper from the cassette paper feed stage 1 is generated, and therefore, the surplus index paper is discharged 6003 (S112, S113). Next, when the index paper 6005 is inserted into the seventh page, the stored paper feed tray is different from the paper feed tray of the index paper inserted into the seventh page. Paper 6004 is performed (S105 to S108).
Here, since the type of index paper to be inserted changes, the stored paper feed stage information is rewritten from the cassette paper feed stage 1 to the cassette paper feed stage 2 (S109).

  Subsequently, when the index paper of the seventh page (6005) and the tenth page (6006) is inserted, the inserted paper from the cassette paper feed stage 2 is not generated thereafter, so that the excess index paper is discharged (6007). (S112, S113). Next, when the index paper is inserted into the 13th page (6009), the stored paper feed stage is different from the paper feed stage of the index paper inserted into the 13th page. Paper discharge (6008) is performed (S105 to S108). Here, since the type of index sheet to be inserted changes, the stored paper feed stage information is transferred from the cassette paper feed stage 2 (paper feed stage information 6012) to the cassette paper feed stage 3 (paper feed stage information 6013). It is rewritten (S109).

Subsequently, the index sheet of the cassette paper feed stage 3 is inserted into the 13th page (tab 6009) and the 16th page (tab 6010), and the job ends. The above is an example of index sheet discharge processing according to the processing flow of FIG.
As a result, it is possible to output a bundle of surplus index sheets for each type of index sheet while obtaining a product 501 that outputs a plurality of types of index sheets in a consistent order. Therefore, when the user reuses surplus index sheets, the operation of rearranging the index sheets for each type can be greatly reduced compared to the conventional case.

[Second Embodiment]
FIG. 12B shows a processing example based on the second discharge order 700. Specifically, at the time of switching to the subsequent paper feeding means, the tab position of the index paper last fed from the previously selected paper feeding means and the paper feeding means to be selected next should be fed. Paper is fed so that the tab position of the index paper is continuous in one set. In this case, the same type of index sheets that are not used in the subsequent sheet feeding unit and have different tab positions are discharged continuously to a specific discharge destination.
More specifically, the CPU 201 controls the cassette paper feeding devices 103A to 103C of the printer unit 108 as follows. After switching each cassette sheet feeding device, an index sheet having the same position as the tab position used by the sheet feeding means selected first from the sheet feeding means to be fed next is designated as a specific sheet discharge destination (for example, FIG. 1). The paper is continuously discharged to the paper discharge tray 105) shown in FIG.
Further, the CPU 201 feeds the index sheet whose tab position is the end position in one set from any of the cassette sheet feeders 103A to 103C, and then moves the index sheet that is not used by the preceding sheet feeding unit to the tab position. The paper is continuously discharged to a specific paper discharge destination so that they are aligned.
In this example, after the index paper 7001 with the first tab position is fed from the cassette paper feeding device 103A, the paper for two pages is ejected, and then the index paper 7002 with the second tab position is fed into the cassette paper feeding device. Paper is fed from 103A. As a result, the printed matter is discharged to the discharge tray 105 so as to be sandwiched between the index sheet 7001 and the index sheet 7002. Next, the CPU 201 switches the index sheet feeding destination to the cassette sheet feeding device 103B. Here, the tab position information indicating the tab position of the cassette paper feeding apparatus 103B managed in accordance with the processing of the flowchart as described above is “1”. Therefore, the CPU 201 discharges the first and second index sheets 7003 with the tab positions from the cassette sheet feeding device 103B, so that the next tab position to be fed is the third position. Paper is discharged onto the tray 105. Thereafter, after the third index sheet 7004 is discharged to the discharge tray 105, the next printed matter is discharged to the discharge tray 105. Then, the CPU 201 discharges the fourth index sheet 7005 to the discharge tray 105. Subsequently, the index sheet is fed from the cassette sheet feeding device 103C, and the first to fourth index sheets 7006 having the first to fourth tab positions are ejected from the cassette tray 105 so that the next tab position to be fed is fifth. Let the paper eject. Thereafter, after the fifth index sheet 7007 is discharged to the discharge tray 105, the next printed matter is discharged to the discharge tray 105. Then, the CPU 201 discharges the sixth index sheet 7008 to the discharge tray 105. Then, the CPU 201 discharges the third to sixth index sheets 7009 having the tab positions from the cassette sheet feeding device 103 </ b> A to the discharge tray 105. Thereafter, the fifth and sixth index sheets 7010 whose tab positions are from the cassette sheet feeding device 103 </ b> B are discharged to the discharge tray 105.
Each process of the present invention can also be realized by executing software (program) acquired via a network or various storage media by a processing device (CPU, processor) such as a personal computer (computer).

  The present invention is not limited to the above embodiment, and various modifications (including organic combinations of the embodiments) are possible based on the spirit of the present invention, and these are excluded from the scope of the present invention. is not.
