Next, the OHP interleaving function, which is a feature of the present embodiment, will be described. In the base machine 1 of this embodiment, the manual feed tray (MSI) 28 and the discharge tray of the transfer corotron 13 and the sorter 3 are substantially on the same plane. It is transported to the transfer corotron 13. Then, the user selects one of the paper supply trays 25 in FIG. 2 on which the paper 27 having the same size as the OHP size is set by using the operation button on the console panel 4. In this embodiment, the size of OHP is A
Limited to 4L and A4S sizes. Then, first, the paper 27 of the size for interleaf paper is placed in the corresponding paper supply tray 25.
Through the image processing unit and output to the sorter 3 having a discharge tray without copying. Then, bypass tray 2
A copy of the original on the platen 17 is made on the OHP sheet conveyed from the position 8, and output as OHP on the slip sheet. This operation is repeated for all OHP documents.

5 is displayed on the LCD 36 of the console panel 4.
The OHP interleaf mode can be entered by calling the application screen shown in FIG. The setting information of the OHP interleaving mode is provided from the UI 39.
4 is output to the LLM 48 in FIG. 4 and the base machine 1 is operated by the IOT controller 44 under the control of the LLM 48. FIG. 6 is a flowchart when the OHP interleaf function is selected on the UI 39, and FIGS. 7 and 8 show LLM.
48 shows a flowchart at 48. FIG. 9 shows LL.
FIG. 7 is a sequence flow diagram when the set number of OHP slip sheets between the M48 and the IOT controller 44 is one. Here, LEF (Long Edge Feed) is a paper transport system with the long side first, and SEF (Short Edge Feed) is a paper transport system with the short side first. Also, this sequence flow diagram shows only the main sequence of the OHP slip-sheet function.

First, a description will be given of a flowchart when the OHP slip-sheet function is selected on the UI 39 of FIG. When the OHP interleaf function button 70 is pressed, the UI 39 notifies the LLM 48 that OHP interleaf has been selected. Bypass tray 2
8 does not have a document size detection function, so that the OHP size cannot be detected. In order to allow the user to specify a sheet 27 of the same size as the OHP sheet as the slip sheet, the user is required to select the sheet supply tray 25 where the sheet 27 is located. OHP paper size (for example, A4LE
When the hard button 35 on the console panel 4 indicating a sheet of the same size as that of F) is pressed, the UI 39 searches the sheet supply tray 25 on which the sheet of the size is set. Since the information of each sheet supply tray 25 is always transmitted to the UI 39, the UI 39 can search for the sheet supply tray 25 having A4 size sheets. When the paper supply tray 25 is present, the LED 3
7 and its paper supply tray 25, for example, A4LEF
The backlight of the display that indicates the paper size such as
The LLM 48 is notified of the number of the sheet supply tray 25. At this time, if there is no paper 27 of the same size as the OHP paper, all the LEDs for the paper supply tray 25 are turned off, and the same paper size as the OHP paper, for example, “A4S”
And "A4L" blink the backlight of the display section, and display "Please insert A4S or A4L" on the LCD 36 (steps 18 to 19).

FIGS. 7 and 8 are flowcharts of the LLM 48 at the time of standby. When the OHP interleaving function is selected, the paper sensor (not shown) of the manual feed tray 28 is used.
There is an OHP sheet (step 12), and a sheet supply tray button 35 having an interleaf sheet 27 of the same sheet size as the OHP sheet is pressed, and the sheet of the designated size is placed in the sheet supply tray 25. Is determined (step 13). In the present embodiment, the paper supply tray 25 on which the paper 27 used for interleaving is set is set to the UI.
39 is selected automatically, but there are cases where the user can set only the size of the slip sheet and cannot set it up to the transport direction. In that case, if DADF2 is used,
DF2 indicates not only the size of the document but also its transport direction (SEF
Or LEF), the DALM 2 finds that the transport directions of the slip-in sheet 27 that should be in the same transport direction as the original drawn on the platen 17 and the OHP sheet are different from each other. Puts the base machine 1 in the Not Ready state, and the UI 39 displays No Pa
A per message is issued (steps 18 and 19).

If there is no OHP paper 27 in the manual feed tray 28 or if there is no paper supply tray 25 for the interleaf paper 27, the LLM 48 does not perform the copying operation, and the UI 39 Display instruction such as "Please set in tray" or "Please insert A4 size paper into paper supply tray 25", and when A4 size paper is inserted, it shifts to Ready state. In this embodiment, when both SEF and LEF sheets of the same size are set in the sheet supply tray 25, the selection setting of the automatic magnification is basically more convenient in SEF than in LEF, so SEF is prioritized. Let me choose.

If there is a paper supply tray 25 for the paper 27 used as an interleaf, the IOT controller 44
To UI39. When the size of the OHP sheet 27 set on the manual feed tray 28 and the size of the original on the platen 17 are different from each other, the OHP sheet size is set based on the information of the interleaf sheet 27 having the same size as the OHP sheet. The UI 39 can also automatically select and set the copy magnification so as to match (step 17). And
When the user presses the copy start button 351, LLM
48 causes the base machine 1 to shift to execution of copying (step 23).

Then, the LLM 48 at the time of copying shown in FIG.
To the control flow. The command to start copying in step 24 in FIG. 9 is instructed to the IOT controller 44 by the shift command to copy in step 23 in FIG. At this time, the scanning of the carriage lamp 19 is started, but the photoconductor 8 is not charged so that copying is not performed on the slip sheet. Here, the scanning is performed only when the slip sheet is conveyed. In addition, since it is difficult to match the operation timing of each operation unit of the base machine 1, scanning is performed even when the slip sheet is transported in order to prevent this.

When the slip sheet is discharged to the discharge tray, the slip sheet is transmitted to the IOT controller 44 so as to change the tray to the manual tray (MSI) 28. Then, the display to that effect is displayed on the UI.
It is transmitted to be 39. At this time, the billing up of the copy number meter (not shown) is stopped. Then, conveyance of the OHP sheet 27 from the manual feed tray 28 to the image processing unit is started. At this time, the charging of the photoconductor 8 is executed simultaneously with the scanning of the carriage lamp 19. Then, when the OHP on which the document surface has been copied is discharged, the paper supply tray 25 is changed to a tray for interleaving paper again and transmitted to the IOT controller 44 and the UI 39. At this time, billing up of the copy number meter is performed. When the DADF 2 is used, the above operation is repeated until the OHP interleaf creation operation for all the originals is completed.

Next, the LLM4 used when creating materials used in a conference or the like
FIG. 11 shows a flowchart of the OHP interleaving function of No. 8.
Steps 40 to 44 show the same procedure as in FIG. Then, even if the OHP interleaving operation for each original is completed, if the set number of sheets is one or more, copying of the original to the OHP sheet 27 is stopped from the second set number of sheets, and the interleaving paper 2
Then, paper is fed only from the slip tray in order to make a copy of the original. At this time, the carriage lamp 1
Instruct the IOT controller 44 to scan 9, charge the photoconductor 8, and operate the sorter 3 on the discharge tray. At this time, the OHP and the slip sheet are output to the non-sort bin 301 of the sorter 3 and the remaining plural sheets of the copied paper 2 for the conference materials are output.
7 can select and output the sort bin 302 or the staple function. Note that a stapler 303 is provided in the sorter 3 shown in FIG. Thus, OH
A plurality of originals can be copied during the P interleaving mode.

First, the ILM controller 44 outputs the OHP interleaving mode and the number of the interleaving paper supply tray 25 from the LLM 48. Here, when the start button 351 of the base machine 1 is pressed, the LLM 48
Transmits to the IOT controller 44 a command to convey the interleaf from the interleaf paper supply tray 25 to the image processing unit. Then, the registration gate sensor 72 detects that the slip sheet has passed through the feed sensor 71 shown in FIG. 2 and has reached the registration gate (not shown), and the IOT controller 44 transmits it to the LLM 48. Since the scanning of the resultant document becomes possible, the LLM 48 causes the IOT controller 44 to open the registration gate and convey the slip sheet.
At this time, the scanning of the carriage lamp 19 is started under the control of the OPT controller 42. However, as described above, the charging of the photoconductor 8 for the interleaving paper is turned off. When the fuser discharge sensor 73 detects the rear end of the slip sheet, the IOT controller 44 notifies the LLM
48. Next, the copy mode of the OHP paper, the number of the OHP paper tray, and the OHP paper feed command are transmitted to the IOT controller 44.

The IOT controller 44 sends OHP sheet feed information to the LLM 48 in the same procedure as that for the slip sheet, and the LLM 48 sends a copy command to the IOT controller 44. At this time, the LLM 48 sends a billing-up command to the IOT controller 44 in order to bill up a copy number meter (not shown). Also, if a jam occurs during the copying operation with the OHP interleaving function, it is not at a glance how many pages have been copied, so the page number is printed on the interleaving paper or the OHP using the annotator function. Is also good.

[0030]

According to the present invention, at least one of the sheets conveyed from the second sheet accommodating section other than the first sheet accommodating section corresponds to the sheet conveyed from the first sheet accommodating section. The same image information as the image information to be recorded is recorded and the first
Is discharged to the second paper discharge position other than the paper discharge position of the first paper storage portion, the first paper storage portion and the second paper storage portion, for example,
Even when different types of paper such as OHP paper and general paper are stored and the same image information is recorded, the paper sorting operation can be easily performed.
