<Inserter operation control flow>
A flowchart of the inserter operation control when the insert mode for inserting the insert sheet is selected as the copy mode will be described with reference to FIGS. In the first embodiment of the present invention, the number of pages to be inserted is three pages, and the number of inserter trays is three. When copy start is selected from the operation unit 40 (step S201), it is determined by what stacking method the insert sheets stacked on the inserter tray are stacked (step S202). As will be described later, this determination is made based on a signal input from the operation unit 40.
[0101]
If the inserter tray stacking method is S-place mode stacking, the number of inserter trays used is substituted for the constant k (step S203). Next, the inserter tray number 1 to be fed first is substituted into the constant i (step S204), and it is determined whether or not it is the timing for inserting the insert sheet (step S205). The timing for inserting the insert paper will be described later with reference to FIGS.
[0102]
Here, when the inserter paper feed timing signal is generated, it is determined that insert paper is inserted, and it is determined whether or not there is insert paper in the inserter tray (step S206). If there is paper, an operation request is issued to the inserter 104. (Step S208). If there is no sheet in the inserter tray i, a message (not shown) is issued to the user to replenish the sheet (step S207), and the process waits until the sheet is replenished. Here, when the inserter tray i operation request = 1, an operation request is issued to the inserter tray i.
[0103]
Next, when the inserter tray i operation request is canceled (step S209), it is determined whether the constants i and k are equal (step S210). Here, if i = k, it is determined whether it is the last part of the job (step S211). If it is not the final part of the job, the process returns to step S204, and if it is the final part of the job, the process ends. If i = k is not satisfied in step S210, i is incremented (step S212), and the process returns to step S205.
[0104]
If the inserter tray stacking method is F-place mode stacking in step S202, the number of inserter trays used is substituted for the constant k (step S213). Next, the inserter tray number 1 to be fed first is substituted for the constant i (step S214), and it is determined whether or not it is the timing for inserting the insert sheet (step S215). Here, if it is time to insert the insert paper, it is determined whether or not there is insert paper in the inserter tray i (step S216). If there is paper, an operation request is issued to the inserter 104 (step S218). If there is no sheet in the inserter tray i, a message is sent to the user to replenish the sheet (step S217), and the process waits until the sheet is replenished.
[0105]
Next, when the operation request of the inserter 104 is canceled (step S219), it is determined whether or not it is the last insert sheet to be inserted (step S220). If it is not the last insert paper, it is determined whether or not there is paper in the inserter tray i (step S221). If there is insert paper, the process returns to step S215, and if there is no insert paper, the inserter tray number to be fed is changed. (Step S222) The inserter tray number k is compared with the inserter tray number i selected for paper feed. If i is equal to or less than k (step S223), the process returns to step S214. If the constant i is greater than or equal to k in step S223, the process returns to step S215, and the inserter tray number for feeding paper is set to 1.
[0106]
Therefore, when the F placement mode is set, continuous running is possible without stopping the job by supplying insert paper to the inserter tray that has run out of paper. 8 and 9 is controlled by the CPU 2002.
[0107]
<Inser Feeding Flow>
A flowchart relating to paper feeding by the inserter 104 will be described with reference to FIG. Here, a case where paper is fed from the inserter tray 1 will be described. When there is an operation request to the inserter 104 (step S101), a paper feed solenoid (not shown) is turned on to transport the insert paper stacked on the inserter tray 1 and the paper feed roller is landed on the insert paper. (Step S102). Next, a transport motor (not shown) is turned on to transport the insert paper (step S103). When the transport motor is turned on, the paper feed roller rotates so that the insert paper can be transported.
[0108]
Next, when the inserter path sensor 41 provided on the transport path of the insert paper detects that the rear end of the insert paper has passed (step S104), the transport motor is turned off (step S105). Next, the paper feed roller is retracted to a position away from the insert paper by turning off the paper feed solenoid. When a series of paper feed operations of the inserter 104 is completed, an operation request release signal for the inserter 104 is generated (step S107), and the paper feed flow of the inserter 104 is terminated.
[0109]
In the above description, the operation when paper is fed from the inserter tray 1 is described. However, even when paper is fed from the inserter trays 2 and 3, the same operation is performed when there is an operation request, and thus detailed description is omitted. Note that the operation of FIG. 10 is controlled by the CPU 2002.
[0110]
<Insert mode judgment flow>
The determination flow of the insert mode will be described with reference to FIG. It is determined whether the insert mode has been selected from the operation unit 40 (step S301). If the insert mode is selected, it is next determined whether or not S-placement is selected as the loading method on the inserter tray (step S302). If it is selected, the S-place mode is set as the insert mode (step S302). Step S303). If the S placement mode is not selected in step S302, it is determined whether the F placement mode is selected (step S304). If the F placement mode is selected, the F placement mode is set (step S305). Note that the operation in FIG. 11 is controlled by the CPU 2002.
[0111]
<Insert paper feed timing flow>
The generation of the inserter paper feed timing when the insert mode is selected will be described with reference to FIGS. First, it is determined whether or not the color page insert key 638 is selected in the operation unit 40 (step S401), and if it is selected, the process waits until the copy start key 614 is selected (step S409). When the copy start key 614 is selected in step S409, document feeding is started (step S410). Next, image reading is performed to determine whether the original is a color original (step S411). If the original is a color original, an inserter feed timing signal is generated. Next, it is determined whether or not it is the last page of the document (step S413). If it is the last page, the process ends. If it is not the last page, the process returns to step S410.
[0112]
If it is not the color page insert mode in step S401, it is determined whether or not it is the page designation insert mode (step S402), and if it is the page designation insert mode, the page to be inserted is input. For example, as shown in FIG. 7C, if the number of document pages is 8 and the pages to be inserted are 3 pages of 4, 6, and 8 pages, the number of pages may be input from the operation unit 40 ( (Not shown).
[0113]
When the input of the insert page is completed (step S403), it is determined whether or not the copy start key 614 has been selected (step S404). When the copy start key 614 is selected, document feeding is started (step S405). At this time, the document pages are also counted, and if the page input in step S403 is reached (step S406), an inserter feed timing signal is generated (step S407). Next, it is determined whether or not it is the last page of the document (step S408). If it is the last page, the process ends. If it is not the last page, the process returns to step S405. 12 and 13 is controlled by the CPU 2002.
[0114]
As described above, according to the copying apparatus according to the first embodiment of the present invention, the CPU 2002 of the control unit 300 of the copying apparatus selects the F placement mode in which a plurality of types of insert sheets are stacked on the inserter tray. If the insert paper loaded on the inserter tray runs out and the insert paper is loaded again on the inserter tray, the insert paper is fed from the inserter tray without stopping the current job. Therefore, there is an effect that paper can be fed from the inserter tray in an appropriate order according to the stacking method of the insert sheets set on the inserter tray. Also, if you insert the insert paper into the inserter tray that has no insert paper before feeding it from the inserter tray on which other insert paper is loaded, the insert paper can be fed from the inserter tray with the insert paper. Therefore, the job can be processed continuously without interrupting the job, the processing time of the job can be shortened, and the use environment for the user can be improved.

Since it explained in full detail, description shall be abbreviate | omitted.
[0120]
Next, the operation of the copying apparatus according to the second embodiment of the present invention configured as described above will be described with reference to FIGS.
[0121]
<Inserter operation control flow>
A flowchart of inserter operation control when the insert mode for inserting the insert sheet is selected as the copy mode will be described with reference to FIGS. In the second embodiment of the present invention, the number of pages to be inserted is three pages and the number of inserter trays is three. When copy start is selected from the operation unit 40 (step S501), it is determined by what stacking method the insert sheets stacked on the inserter tray are stacked (step S502). As will be described later, this determination is made based on a signal input from the operation unit 40.
[0122]
If the inserter tray stacking method is the S-place mode stacking, the number of inserter trays used is substituted for the variable k (step S503). Next, the inserter tray number 1 to be fed first is substituted into the variable i (step S504), and it is determined whether or not it is the timing for inserting the insert sheet (step S505). The timing for inserting the insert paper will be described later with reference to FIGS.
[0123]
Here, when the inserter paper feed timing signal is generated, it is determined that the insert paper is inserted, and it is determined whether there is insert paper in the inserter tray (step S506). If there is paper, an operation request is issued to the inserter 104. (Step S508). If there is no sheet in the inserter tray i, a message (not shown) is issued to the user to replenish the sheet (step S507), and the process waits until the sheet is replenished. If canceling of the job is selected during the waiting (step S550), the process is terminated. Here, when the inserter tray i operation request = 1, an operation request is issued to the inserter tray i.
[0124]
Next, when the inserter tray i operation request is canceled (step S509), it is determined whether or not the variables i and k are equal (step S510). Here, if i = k, it is determined whether it is the last part of the job (step S511). If it is not the final part of the job, the process returns to step S504, and if it is the final part of the job, the process ends. If i = k is not satisfied in step S510, i is incremented (step S512), and the process returns to step S505.
[0125]
If the loading method of the inserter tray is F-place mode loading in step S502, the total number of inserter trays is substituted for variable k (step S513). Next, the inserter tray number 1 to be fed first is substituted for the variable i (step S514), and it is determined whether or not it is the timing to insert the insert sheet (step S515). Here, if it is time to insert the insert paper, it is determined whether or not there is insert paper in the inserter tray i (step S516). If there is paper, an operation request is issued to the inserter 104 (step S518). If there is no sheet in the inserter tray i, a message is sent to the user to replenish the sheet (step S517), and the process waits until the sheet is replenished. If canceling of the job is selected during the standby (step S527), the process ends.
[0126]
Next, when the operation request of the inserter 104 is canceled (step S519), it is determined whether or not it is the last insert sheet to be inserted (step S520). If it is not the last insert sheet, the value i is stored in the variable ii (step S521). And inserter tray i i In step S522, when it is determined that there is an insert sheet, it is determined whether the no-paper flag is 1 (step S528). If it is determined that the no-paper flag is not 1, step S531 is executed. When it is determined that the paper-out flag is 1, the paper-out flag is cleared to 0 (step S529), and a predetermined time has elapsed (step S530). After a predetermined time has elapsed, the value of variable ii is substituted into variable i. That is, the paper feed inserter tray number is set to the value ii (step S531). Then, the process returns to step S516.
[0127]
If there is no insert paper in step S522, ii is incremented, that is, the inserter tray number for detecting the presence or absence of the insert paper is incremented (step S523). Next, the inserter tray number ii in which the presence or absence of the insert paper on the inserter tray is detected is compared with the inserter tray number ii selected for paper feed, and ii is equal to i, that is, the insert paper is placed on all inserter trays. When it is determined that there is no paper, the no paper flag is set to 1 (step S532). Then, a message is issued to the user to replenish the paper (step S533), and the process waits until the paper is replenished. If canceling of the job is selected during the standby (step S534), the process is terminated.
[0128]
If it is determined in step S524 that ii is not equal to i, that is, it is not determined that there is no insert paper on all the inserter trays, step S525 is executed. The variable k is compared with the inserter tray number ii selected for paper feed. If ii is equal to or smaller than k (step S525), the process returns to step S522. If the variable ii is greater than or equal to k in step S525, ii is set to 1, that is, the inserter tray number for detecting presence / absence of insert paper is set to 1 (step S526).
[0129]
Therefore, when the F placement mode is set, continuous running is possible without stopping the job by supplying insert paper to the inserter tray that has run out of paper. In addition, when there is no insert paper on all the inserter trays during the job, the job can be automatically restarted when it is detected that the insert paper is again placed on the inserter tray. 14 to 17 is controlled by the CPU 2002.
[0130]
<Inser Feeding Flow>
A flowchart relating to paper feeding by the inserter 104 will be described with reference to FIG. Here, a case where paper is fed from the inserter tray 1 will be described. When there is an operation request to the inserter 104 (step S601), a feed solenoid (not shown) is turned on to transport the insert paper loaded on the inserter tray 1 and the paper feed roller is landed on the insert paper. (Step S602). Next, in order to transport the insert paper, a transport motor (not shown) is turned on (step S603). When the transport motor is turned on, the paper feed roller rotates so that the insert paper can be transported.
[0131]
Next, when the inserter path sensor 41 provided on the transport path of the insert paper detects that the trailing edge of the insert paper has passed (step S604), the transport motor is turned off (step S605). Next, the paper feed roller is retracted to a position away from the insert paper by turning off the paper feed solenoid. When a series of paper feed operations of the inserter 104 is completed, an operation request release signal for the inserter 104 is generated (step S607), and the paper feed flow of the inserter 104 is terminated.
[0132]
In the above description, the operation when paper is fed from the inserter tray 1 is described. However, even when paper is fed from the inserter trays 2 and 3, the same operation is performed when there is an operation request, and thus detailed description is omitted. Note that the operation in FIG. 18 is controlled by the CPU 2002.
[0133]
<Insert mode judgment flow>
The insert mode determination flow will be described with reference to FIG. It is determined whether the insert mode is selected from the operation unit 40 (step S701). If the insert mode is selected, it is next determined whether or not S-placement is selected as the loading method on the inserter tray (step S702). If it is selected, the S-place mode is set as the insert mode ( Step S703). If the S placement mode is not selected in step S702, it is determined whether or not the F placement mode is selected (step S704). If the F placement mode is selected, the F placement mode is set (step S705). Note that the operation in FIG. 19 is controlled by the CPU 2002.
[0134]
<Insert paper feed timing flow>
The generation of inserter sheet feeding timing when the insert mode is selected will be described with reference to FIGS. First, it is determined whether or not the color page insert key 638 is selected in the operation unit 40 (step S801). If it is selected, the process waits until the copy start key 614 is selected (step S809). When the copy start key 614 is selected in step S809, document feeding is started (step S810). Next, image reading is performed to determine whether the original is a color original (step S811). If the original is a color original, an inserter feed timing signal is generated. Next, it is determined whether or not it is the last page of the document (step S813). If it is the last page, the process ends. If it is not the last page, the process returns to step S810.
[0135]
If it is not the color page insert mode in step S801, it is determined whether or not it is the page designated insert mode (step S802), and if it is the page designated insert mode, the page to be inserted is input. For example, as shown in FIG. 7C, if the number of document pages is 8 and the pages to be inserted are 3 pages of 4, 6, and 8 pages, the number of pages may be input from the operation unit 40 ( (Not shown).
[0136]
When the input of the insert page is completed (step S803), it is determined whether or not the copy start key 614 has been selected (step S804). When the copy start key 614 is selected, document feeding is started (step S805). At this time, the document pages are also counted. If the page input in step S803 is reached (step S806), an inserter paper feed timing signal is generated (step S807). Next, it is determined whether or not it is the last page of the document (step S808). If it is the last page, the process ends. If not, the process returns to step S805. 20 and 21 is controlled by the CPU 2002.
[0137]
<Operation start determination process>
Next, the operation start determination process for determining the operation start of the entire system will be described with reference to the flowchart of FIG. This is a process of determining a start condition for operating the copying apparatus. First, the state of the copy start key 614 of the operation unit 40 is determined (step S901), and when the copy start key 614 is turned on, an image forming operation is started (step S906). This step S906 is continued until the image forming operation is completed, a series of unit jobs are processed, and the process returns to step S901 after the end of the job. If the copy start key 614 is not turned on in step S901, it is determined whether or not the mode selected by the operation unit 40 is the insert mode for inserting the insert paper placed on the inserter tray into the output paper ( Step S902) If the mode is not the insert mode, the process returns to Step S901.
[0138]
If it is the insert mode, 1 is substituted for the variable i as an initial value (step S903). This variable i indicates a plurality of inserter tray stages, and when i = 1, it indicates the uppermost inserter tray. Next, it is determined whether or not there is paper in the inserter tray indicated by 1 (step S904). If there is paper in the inserter tray 1, an image forming operation is started (step S906). If there is no sheet in the inserter tray 1, 1 is added to the variable up to k, which is the number of inserter trays, and it is determined whether or not there is a sheet in the inserter tray (steps S905 and S907).
[0139]
As described above, when the insert mode is selected, the presence / absence of sheets on all the inserter trays is checked / determined, and if any of the inserter trays has sheets, the image forming operation is started immediately. That is, the image forming operation can be started simply by placing the sheet on the inserter tray, and the operability is improved. Note that the operation in FIG. 22 is controlled by the CPU 2002.
[0140]
As described above, according to the copying apparatus according to the second embodiment of the present invention, when operating the insert mode for inserting the insert paper into the output paper on which the image has been formed, When the insert mode for inserting the insert paper from the inserter tray together with the image forming conditions such as the density is selected, the image forming operation as a system operation is started by placing the insert paper to be inserted on the inserter tray. This configuration eliminates multiple useless and complicated operations as the specification for operating in the insert mode, reduces the possibility of erroneous operations by improving user operability, and specifies the operation mode. By shortening the time, it is possible to improve the processability of the system.

[0145]
The overall configuration shown in FIGS. 1 to 6, the configuration of the image signal control unit 77, the control unit 300, and the operation unit 40 in the copying apparatus according to the third embodiment of the present invention are described in the first embodiment. Since it explained in full detail, description shall be abbreviate | omitted.
[0146]
Next, the operation of the copying apparatus according to the third embodiment of the present invention configured as described above will be described with reference to FIG.
[0147]
In the second embodiment, when the insert mode is selected, the image forming operation is started when paper is detected on the inserter tray. However, if there is a different insert mode, the automatic operation starts depending on the mode. There may be cases where it does not seem like it is not complete. Therefore, it is possible to eliminate the possibility of such a problem by providing detailed conditions for the designated insert mode. Specifically, as an insert mode, control is performed so that an image forming operation is started when there is paper in the inserter tray only in an operation mode (F mode) in which insert paper is continuously fed from the same inserter tray. It is to be.
[0148]
<Operation start determination process>
The operation start determination process for determining the operation start of the entire system will be described with reference to the flowchart of FIG. This is a process of determining a start condition for operating the copying apparatus. First, the state of the copy start key 614 of the operation unit 40 is determined (step S1001). When the copy start key 614 is turned on, an image forming operation is started (step S1006). This step S1006 is continuously performed until the image forming operation is completed, a series of unit jobs are processed, and the process returns to step S1001 after the end of the job. If the copy start key 614 is not turned on in step S1001, it is determined whether or not the mode selected by the operation unit 40 is the insert mode for inserting the insert paper placed on the inserter tray into the output paper ( In step S1002), if it is not the insert mode, the process returns to step S1001.
[0149]
If it is in the insert mode, it is determined whether or not it is the insert operation mode (F mode) for continuous feeding from the same inserter tray (step S1008), and if it is not the F mode, the process returns to step S1001. In the F mode, 1 is substituted for the variable i as an initial value (step S1003). This variable i indicates a plurality of inserter tray stages, and when i = 1, it indicates the uppermost inserter tray. Next, it is determined whether or not there is paper in the inserter tray indicated by 1 (step S1004). If there is paper in the inserter tray 1, an image forming operation is started (step S1006). If there is no sheet in the inserter tray 1, 1 is added to the variable up to k, which is the number of inserter trays, and it is determined whether or not there is a sheet in the inserter tray (steps S1005 and S1007).
[0150]
As described above, when the insert mode is selected, the presence / absence of sheets on all the inserter trays is checked / determined, and if any of the inserter trays has sheets, the image forming operation is started immediately. Also in this case, the image forming operation can be started simply by placing the sheet on the inserter tray, and the operability is improved. Note that the operation of FIG. 23 is controlled by the CPU 2002.
[0151]
As described above, according to the copying apparatus according to the third embodiment of the present invention, as in the second embodiment, the insert mode for inserting the insert paper into the image-formed output paper is operated. When the insert mode for inserting the insert paper from the inserter tray is selected together with the image forming conditions such as magnification and density in the operation unit 40, the insert paper to be inserted is placed on the inserter tray. By configuring the system to start the image forming operation, it eliminates multiple wasteful and complicated operations that are specified to operate in the insert mode, and the possibility of erroneous operations is improved by improving user operability. By reducing the time required for specifying the operation mode, it is possible to improve the system processability.

[0157]
Next, the operation of the copying apparatus according to the fourth embodiment of the present invention configured as described above will be described with reference to FIGS.
[0158]
<Inserter operation control flow>
A flowchart of the inserter operation control when the insert mode for inserting the insert sheet is selected as the copy mode will be described with reference to FIGS. In the fourth embodiment of the present invention, the number of pages to be inserted is three pages and the number of inserter trays is three. When the copy start is selected from the operation unit 40 (step S1101), it is determined how the insert sheets stacked on the inserter tray are stacked (step S1102). As will be described later, this determination is made based on a signal input from the operation unit 40.
[0159]
If the inserter tray stacking method is the S-place mode stacking, the number of inserter trays used is substituted for the variable k (step S1103). Next, the inserter tray number 1 to be fed first is substituted into the variable i (step S1104), and it is determined whether it is the timing for inserting the insert sheet (step S1105). The timing for inserting the insert paper will be described later with reference to FIGS.
[0160]
Here, when an inserter paper feed timing signal is generated, it is determined that insert paper is inserted, and it is determined whether or not there is insert paper in the inserter tray (step S1106). If there is paper, an operation request is issued to the inserter 104. (Step S1108). If there is no sheet in the inserter tray i, a message (not shown) is issued to the user to replenish the sheet (step S1107), and the process waits until the sheet is replenished. If cancellation of the job is selected during the standby (step S1150), the process ends. Here, when the inserter tray i operation request = 1, an operation request is issued to the inserter tray i.
[0161]
Next, when the inserter tray i operation request is canceled (step S1109), it is determined whether or not the variables i and k are equal (step S1110). Here, if i = k, it is determined whether it is the last part of the job (step S1111). If it is not the final part of the job, the process returns to step S1104, and if it is the final part of the job, the process ends. If i = k is not satisfied in step S1110, i is incremented (step S1112), and the process returns to step S1105.
[0162]
If the inserter tray stacking method is F-place mode stacking in step S1102, the total number of inserter trays is substituted for variable k (step S1113). Next, the inserter tray number 1 to be fed first is substituted for the variable i (step S1114), and it is determined whether or not it is the timing to insert the insert sheet (step S1115). Here, if it is time to insert the insert paper, it is determined whether or not there is insert paper in the inserter tray i (step S1116). If there is paper, an operation request is issued to the inserter 104 (step S1118). If there is no sheet in the inserter tray i, a message is sent to the user to replenish the sheet (step S1117), and the process waits until the sheet is replenished. If cancellation of the job is selected during the standby (step S1127), the process ends.
[0163]
Next, when the operation request of the inserter 104 is canceled (step S1119), it is determined whether or not it is the last insert sheet to be inserted (step S1120). If it is not the last insert sheet, the value i is stored in the variable ii (step S1121). Then, it is determined whether or not there is a sheet in the inserter tray i (step S1122). When it is determined that there is an insert sheet, it is determined whether or not the no-paper flag is 1 (step S1128). When it is determined that the paper-out flag is not 1, step S1131 is executed. If it is determined that the paper-out flag is 1, the paper-out flag is cleared to 0 (step S1129), and a predetermined time has elapsed (step S1130). After a predetermined time has elapsed, the value of variable ii is substituted into variable i. That is, the paper feed inserter tray number is set to the value ii (step S1131). Then, the process returns to step S1116.
[0164]
If there is no insert paper in step S1122, ii is incremented, that is, the inserter tray number for detecting the presence or absence of the insert paper is incremented (step S1123). Next, the inserter tray number ii in which the presence or absence of the insert paper on the inserter tray is detected is compared with the inserter tray number ii selected for paper feed, and ii is equal to i, that is, the insert paper is placed on all inserter trays. When it is determined that there is no paper, the no paper flag is set to 1 (step S1132). Then, a message is issued to the user to replenish the paper (step S1133), and the process waits until the paper is replenished. If cancellation of the job is selected during the standby (step S1134), the process ends.
[0165]
If it is determined in step S1124 that ii is not equal to i, that is, if there is no insert paper on all the inserter trays, step S1125 is executed. The variable k is compared with the inserter tray number ii selected for paper feed. If ii is equal to or smaller than k (step S1125), the process returns to step S1122. If the variable ii is greater than or equal to k in step S1125, ii is set to 1, that is, the inserter tray number for detecting presence / absence of insert paper is set to 1 (step S1126).
[0166]
Therefore, when the F placement mode is set, continuous running is possible without stopping the job by supplying insert paper to the inserter tray that has run out of paper. In addition, when there is no insert paper on all the inserter trays during the job, the job can be automatically restarted when it is detected that the insert paper is again placed on the inserter tray. The operations in FIGS. 24 to 27 are controlled by the CPU 2002.
[0167]
<Inser Feeding Flow>
A flowchart relating to paper feeding by the inserter 104 will be described with reference to FIG. Here, a case where paper is fed from the inserter tray 1 will be described. When there is an operation request to the inserter 104 (step S1201), a feed solenoid (not shown) is turned on to transport the insert paper loaded on the inserter tray 1, and the paper feed roller is landed on the insert paper. (Step S1202). Next, in order to transport the insert paper, a transport motor (not shown) is turned on (step S1203). When the transport motor is turned on, the paper feed roller rotates so that the insert paper can be transported.
[0168]
Next, when the inserter path sensor 41 provided on the transport path of the insert paper detects that the rear end of the insert paper has passed (step S1204), the transport motor is turned off (step S1205). Next, the paper feed roller is retracted to a position away from the insert paper by turning off the paper feed solenoid. When a series of paper feed operations of the inserter 104 is completed, an operation request release signal for the inserter 104 is generated (step S1207), and the paper feed flow of the inserter 104 is terminated.
[0169]
In the above description, the operation when paper is fed from the inserter tray 1 is described. However, even when paper is fed from the inserter trays 2 and 3, the same operation is performed when there is an operation request, and thus detailed description is omitted. The operation of FIG. 28 is controlled by the CPU 2002.
[0170]
<Insert mode judgment flow>
The insert mode determination flow will be described with reference to FIG. It is determined whether or not the insert mode has been selected from the operation unit 40 (step S1301). If the insert mode is selected, it is next determined whether or not S placement is selected as the loading method on the inserter tray (step S1302). If selected, the S placement mode is set as the insert mode ( Step S1303). If the S placement mode is not selected in step S1302, it is determined whether the F placement mode has been selected (step S1304). If the F placement mode is selected, the F placement mode is set (step S1305). Note that the operation of FIG. 29 is controlled by the CPU 2002.
[0171]
<Insert paper feed timing flow>
Generation of inserter paper feed timing when the insert mode is selected will be described with reference to FIGS. First, it is determined whether the color page insert key 638 is selected in the operation unit 40 (step S1401), and if it is selected, the process waits until the copy start key 614 is selected (step S1409). When the copy start key 614 is selected in step S1409, the document feed is started (step S1410). Next, image reading is performed to determine whether the original is a color original (step S1411). If the original is a color original, an inserter feed timing signal is generated. Next, it is determined whether or not it is the last page of the document (step S1413). If it is the last page, the process ends. If it is not the last page, the process returns to step S1410.
[0172]
If it is not the color page insert mode in step S1401, it is determined whether or not it is the page designated insert mode (step S1402). If it is the page designated insert mode, the page to be inserted is input. For example, as shown in FIG. 7C, if the number of document pages is 8 and the pages to be inserted are 3 pages of 4, 6, and 8 pages, the number of pages may be input from the operation unit 40 ( (Not shown).
[0173]
When the input of the insert page is completed (step S1403), it is determined whether or not the copy start key 614 has been selected (step S1404). When the copy start key 614 is selected, document feeding is started (step S1405). At this time, the document pages are also counted, and if the page input in step S1403 is reached (step S1406), an inserter feed timing signal is generated (step S1407). Next, it is determined whether or not it is the last page of the document (step S1408). If it is the last page, the process ends. If it is not the last page, the process returns to step S1405. 30 and 31 is controlled by the CPU 2002.
[0174]
As described above, according to the copying apparatus according to the fourth embodiment of the present invention, the insert paper loaded on the inserter tray disappears, the job is temporarily interrupted, and then the insert paper is set on the inserter tray. By continuing the job after a predetermined time after detecting that, it is possible to save the user from inputting the job resumption from the operation unit 40 of the image forming apparatus located away from the inserter 104, and the usage environment for the user There is an effect that it can be improved.

[0181]
<Inserter operation control flow>
A flowchart of the inserter operation control when the insert mode for inserting the insert sheet is selected as the copy mode will be described with reference to FIGS. In the fifth embodiment of the present invention, the number of pages to be inserted is three pages and the number of inserter trays is three. When the copy start is selected from the operation unit 40 (step S1501), it is determined how the insert sheets stacked on the inserter tray are stacked (step S1502). As will be described later, this determination is made based on a signal input from the operation unit 40.
[0182]
If the inserter tray stacking method is the S-place mode stacking, the number of inserter trays used is substituted for the variable k (step S1503). Next, the inserter tray number 1 to be fed first is substituted into the variable i (step S1504), and it is determined whether or not it is time to insert the insert sheet (step S1505). The timing for inserting the insert paper will be described later with reference to FIGS.
[0183]
Here, when the inserter paper feed timing signal is generated, it is determined that the insert paper is inserted, and it is determined whether or not there is insert paper in the inserter tray (step S1506). If there is paper, an operation request is issued to the inserter 104. (Step S1508). If there is no sheet in the inserter tray i, a message (not shown) is issued to the user to replenish the sheet (step S1507), and the process waits until the sheet is replenished. If cancellation of the job is selected during the standby (step S1550), the process ends. Here, when the inserter tray i operation request = 1, an operation request is issued to the inserter tray i.
[0184]
Next, when the inserter tray i operation request is canceled (step S1509), it is determined whether the variables i and k are equal (step S1510). Here, if i = k, it is determined whether it is the last part of the job (step S1511). If it is not the final part of the job, the process returns to step S1504, and if it is the final part of the job, the process ends. If i = k is not satisfied in step S1510, i is incremented (step S1512), and the process returns to step S1505.
[0185]
If the inserter tray stacking method is F-place mode stacking in step S1502, the total number of inserter trays is substituted for variable k (step S1513). Next, the inserter tray number 1 to be fed first is substituted for the variable i (step S1514), and it is determined whether or not it is the timing to insert the insert sheet (step S1515). Here, if it is time to insert the insert paper, it is determined whether or not there is insert paper in the inserter tray i (step S1516). If there is paper, an operation request is issued to the inserter 104 (step S1518). If there is no sheet in the inserter tray i, a message is sent to the user to replenish the sheet (step S1517), and the process waits until the sheet is replenished. If cancellation of the job is selected during the standby (step S1527), the process ends.
[0186]
Next, when the operation request of the inserter 104 is canceled (step S1519), it is determined whether or not it is the last insert sheet to be inserted (step S1520). If it is not the last insert sheet, the value i is stored in the variable ii (step S1521). Then, it is determined whether or not there is a sheet in the inserter tray i (step S1522). When it is determined that there is an insert sheet, it is determined whether or not the no-paper flag is 1 (step S1528). When it is determined that the paper-out flag is not 1, step S1531 is executed. When it is determined that the paper-out flag is 1, the paper-out flag is cleared to 0 (step S1529), and the process waits for the copy start to be selected from the operation unit 40 (step S1530). After copy start is selected, the value of variable ii is substituted for variable i. That is, the inserter tray number to be fed is set to the value ii (step S1531). Then, the process returns to step S1516.
[0187]
If there is no insert paper in step S1522, ii is incremented, that is, the inserter tray number for detecting the presence or absence of the insert paper is incremented (step S1523). Next, the inserter tray number ii that detects the presence or absence of the insert paper on the inserter tray is compared with the inserter tray number ii selected for feeding, and ii and i are equal. When it is determined that there is no paper, the paper out flag is set to 1 (step S1532). Then, a message is issued to the user to replenish paper (step S1533), and the process waits until the paper is replenished. If cancellation of the job is selected during the standby (step S1534), the process ends.
[0188]
If it is determined in step S1524 that ii is not equal to i, that is, it is not determined that there is no insert paper on all inserter trays, step S1525 is executed. The variable k is compared with the inserter tray number ii selected for paper feed. If ii is equal to or smaller than k (step S1525), the process returns to step S1522. If the variable ii is greater than or equal to k in step S1525, ii is set to 1, that is, the inserter tray number for detecting the presence / absence of insert paper is set to 1 (step S1526).
[0189]
Therefore, when the F placement mode is set, continuous running is possible without stopping the job by supplying insert paper to the inserter tray that has run out of paper. In addition, when there is no insert paper on all the inserter trays during the job, the job can be automatically restarted when it is detected that the insert paper is again placed on the inserter tray. The operations in FIGS. 32 to 35 are controlled by the CPU 2002.
[0190]
<Inser Feeding Flow>
A flowchart relating to paper feeding by the inserter 104 will be described with reference to FIG. Here, a case where paper is fed from the inserter tray 1 will be described. When there is an operation request to the inserter 104 (step S1601), a paper feed solenoid (not shown) is turned on to transport the insert paper loaded on the inserter tray 1 and the paper feed roller is landed on the insert paper. (Step S1602). Next, in order to transport the insert paper, a transport motor (not shown) is turned on (step S1603). When the transport motor is turned on, the paper feed roller rotates so that the insert paper can be transported.
[0191]
Next, when the inserter path sensor 41 provided on the transport path of the insert paper detects that the rear end of the insert paper has passed (step S1604), the transport motor is turned off (step S1605). Next, the paper feed roller is retracted to a position away from the insert paper by turning off the paper feed solenoid. When a series of paper feed operations of the inserter 104 is completed, an operation request release signal for the inserter 104 is generated (step S1607), and the paper feed flow of the inserter 104 is terminated.
[0192]
In the above description, the operation when paper is fed from the inserter tray 1 is described. However, even when paper is fed from the inserter trays 2 and 3, the same operation is performed when there is an operation request, and thus detailed description is omitted. The operation of FIG. 36 is controlled by the CPU 2002.
[0193]
<Insert mode judgment flow>
The determination flow of the insert mode will be described with reference to FIG. It is determined whether or not the insert mode has been selected from the operation unit 40 (step S1701). If the insert mode is selected, it is next determined whether or not S-placement is selected as the loading method on the inserter tray (step S1702). If it is selected, the S-place mode is set as the insert mode ( Step S1703). If the S placement mode is not selected in step S1702, it is determined whether the F placement mode is selected (step S1704). If the F placement mode is selected, the F placement mode is set (step S1705). Note that the operation of FIG. 37 is controlled by the CPU 2002.
[0194]
<Insert paper feed timing flow>
Generation of inserter paper feed timing when the insert mode is selected will be described with reference to FIGS. First, it is determined whether or not the color page insert key 638 is selected in the operation unit 40 (step S1801), and if it is selected, the process waits until the copy start key 614 is selected (step S1809). When the copy start key 614 is selected in step S1809, document feeding is started (step S1810). Next, image reading is performed to determine whether the original is a color original (step S1811). If the original is a color original, an inserter feed timing signal is generated. Next, it is determined whether or not it is the last page of the document (step S1813). If it is the last page, the process ends.
[0195]
If it is not the color page insert mode in step S1801, it is determined whether or not it is the page designated insert mode (step S1802), and if it is the page designated insert mode, the page to be inserted is input. For example, as shown in FIG. 7C, if the number of document pages is 8 and the pages to be inserted are 3 pages of 4, 6, and 8 pages, the number of pages may be input from the operation unit 40 ( (Not shown).
[0196]
When the input of the insert page is completed (step S1803), it is determined whether or not the copy start key 614 has been selected (step S1804). When the copy start key 614 is selected, document feeding is started (step S1805). At this time, the document pages are also counted, and if the page input in step S1803 is reached (step S1806), an inserter feed timing signal is generated (step S1807). Next, it is determined whether or not it is the last page of the document (step S1808). If it is the last page, the process ends. If not, the process returns to step S1805. The operations in FIGS. 38 and 39 are controlled by the CPU 2002.
[0197]
As described above, according to the copying apparatus according to the fifth embodiment of the present invention, after the insert paper loaded on the inserter tray runs out and the job is temporarily interrupted, the user sets the insert paper on the inserter tray. After confirming that all the insert sheets that should be set in one inserter tray have been loaded, the user continues the job by selecting the copy start and instructing the job to resume. Thus, it is possible to prevent an erroneous insert operation and to improve the use environment for the user.
