The sheets discharged to the first and second bins 206a and 206b are stacked so that the sheets corresponding to the smaller page numbers face up, and the sheet corresponding to the fourth page is newly copied. Has been replaced by. Then, the sheet corresponding to the fourth page of the series of copied sheets is discharged to the 3-bin 206c as an unnecessary sheet.

Next, the characteristics of the operation of the copying apparatus 2 will be described with reference to the drawings. First, a normal mode for normally copying an original image placed on the original table 11 will be described with reference to FIGS. 1 to 3.

In the normal mode, the document D to be copied is AD
After being set on the document tray 101 of F100, the copy start key 309 of the operation panel 300 is turned on, so that the empty sensor 102 is operated by the ADF CPU 130.
Is confirmed to be on, and ADFCPU
The pickup roller 103 is driven according to the supply of a drive current from the motor drive circuit 131 to the paper feed motor corresponding to the instruction of 130, and the lowermost original of the original D set on the original tray 101 is the paper feed roller 104. Will be guided to.

The document D guided to the paper feed roller 104 is
The sheet is further conveyed by the sheet feeding roller 104 toward the aligning roller pair 105. Here, when the leading edge of the document D passes through the aligning sensor 106, a clutch (not shown) is turned on via the mechanical controller 133, and the aligning roller pair 105 is stopped. As a result, the document D taken out from the document tray via the pickup roller 103 is temporarily stopped, so that the inclination of the document D with respect to the document conveyance direction is corrected and the document serving as a reference for image formation timing is corrected. The tip position of D is specified.

Then, the carry motor is rotated by the drive current from the motor drive circuit 131 to the carry motor (not shown) under the control of the ADF CPU 130, and the carry belt 10 is rotated.
7 is rotated. At a predetermined timing (for example, when the rotation of the conveyor belt 107 reaches a predetermined rotation) after the conveyor belt 107 is rotated, a clutch (not shown) is turned off via the mechanical controller 133, and the conveyor belt pair 105 is conveyed. The document D is fed to the belt 107. After that, the conveyor belt 1 is driven by the conveyor motor.
When the document 07 is rotated for a predetermined time, the document D is transferred to the apparatus main body 2
The document table 11 is conveyed. The conveyance belt 107 is stopped after a certain time (predetermined by the distance between the aligning sensor 106 and the indicating plate 12) has passed after the trailing edge of the document D has passed the aligning sensor 106.

On the other hand, when the leading edge of the document D is detected by the aligning sensor 106, the CPU 7 (of the apparatus main body 2)
7 is informed that the document D is being conveyed.
As a result, in the apparatus main body 2, each part of the image reading unit 4 and the image forming unit 6 shifts to the preparation stage for image formation according to the instruction from the CPU 77.

When the conveyance belt 107 is stopped and the ADF CPU 130 checks the completion of the document conveyance (for copying), the copy enable signal is sent to the internal bus 79.
Is output from the ADF CPU 130 to the CPU 77 via.

As a result, the main motor (not shown) is rotated by the control of the motor drive circuit 82 corresponding to the instruction of the CPU 77, and the photosensitive drum 30 is rotated at a predetermined speed. At the same time, the high voltage generation circuit 83 (corresponding to the instruction from the CPU 77) applies a predetermined potential to the photosensitive drum 30 from the charging charger 31 and the transfer / peel charger 33.

Then, (corresponding to the instruction from the CPU 77)
The lamp lighting circuit 81 lights the illumination lamp 13 of the first carriage 16 at a predetermined brightness, and the motor drive circuit 8
The first carriage 16 is moved at a predetermined speed along the document D on the document table 11 by the rotation of the pulse motor under the control of 2.

The image information recorded on the document D placed on the document table 11 is reflected light generated by being illuminated through the exposure lamp 13 and the reflector 14 and is reflected by the first mirror of the first carriage 16. 15, the second mirror 20 and the third mirror 21 of the second carriage 17, the imaging lens 22, the fourth mirror 23 and the fifth mirror 24, and the exposure mirror 25 are passed (or reflected) in order,
Guided by the photoconductor drum 30.

The reflected light from the document D guided to the photosensitive drum 30, that is, image information is converted by the photosensitive drum 30 into an electrostatic latent image corresponding to the image information. The electrostatic latent image on the photoconductor drum 30 is developed as a toner image by the toner supplied from the developing device 32, and then is fed from a predetermined cassette to the timing roller 58 via the transfer / peeling device 33. The sheet P is transferred onto the sheet P in a state where the front end of the sheet P is aligned with the position of the toner image on the photoconductor drum 30 by the timing roller 58.

The paper P on which the toner image has been transferred is separated by the peeling claw 3.
4 and the transfer / peeling device 33 separates the photosensitive drum 30 from the photosensitive drum 30, and the carrier device 52 conveys the toner image to the fixing device 53. You will be guided to 64. The paper P guided to the discharge port 54 side is discharged to a predetermined sort tray of the sorter 200 connected to the discharge light.

The photoconductor drum 30 which has delivered the toner image onto the paper is used for the next image formation after the cleaning device 35 and the static eliminator 36 have removed the electric charge and the toner remaining on the surface.

When the number of copies is 2 or more, or when the next original is supplied on the original table 11,
Under the control of the CPU 77, the above series of copying steps are repeated.

On the other hand, a predetermined step in the copying step up to this point, for example, the trailing edge of the sheet P is the timing roller 58.
CPU 77 through the input circuit 85
Then, the passage of the paper P is notified.

When the CPU 77 is notified of the passage of the paper P, the CPU 77 determines whether the number of copies to be input by the operation panel 300 as an input device is 1 and the number of copies to be input. It is checked whether the copying has been repeated. If it is confirmed that the copying of the document D currently located on the document table 11 is completed, the CPU 77 sends the next document D to the ADF CPU 130 via the internal bus 79.
It is required to send the documents (replacement of originals).

The CPU 77 of the apparatus body 2 causes the ADF 10
When the document replacement is requested to 0, the ADF CPU 130
By the drive current from the motor drive circuit 131 to the not-shown conveyor motor under the control of 1, the conveyor motor is rotated, and the conveyor belt 107 is rotated again. As a result, the first document currently set on the document table 11 is conveyed toward the reversing roller 110.

The original D conveyed toward the reversing roller 110 is discharged to the original receiver 121 of the main body cover 120 by the flapper 111 and the paper discharge roller 112. At the same time, a predetermined timing (for example, the jam sensor 113
When the leading edge of the first document is detected by
The pickup roller 103 is driven under the control of U130, and the second document is guided from the document D set on the document tray 101 to the paper feed roller 104. Thereafter, similarly to the first original, the second original is set on the original table 11, and the copying process for the second original is started.

When the original D is a double-sided original and the double-sided copy mode is set by the operation panel 300, the flapper 111 which is switched according to the instruction from the mechanical controller 133 and the subsequently rotated flapper 111. It goes without saying that the first document is returned to the conveyor belt 107 by the reversing roller 110, and the image information on the back surface of the first document is copied before the feeding of the second document.

Next, after confirming that the paper corresponding to the replacement page has been discharged, the CPU 77 controls in ST18 to move the sorter unit to a bin corresponding to BUSU, that is, one bin.

Next, in ST19, it is detected whether or not the ADF is on. That is, the CPU 77 detects whether the replacement page is a document or a copied sheet based on the output signal from the empty sensor 102 of the ADF. That is, if the empty sensor of the ADF is on, it is recognized that the replacement page is the original.

Subsequently, the CPU 77 operates the ADF to instruct the ADF CPU to place the original placed on the ADF on the original table. The size of the sheet to be copied is determined based on the size of the original placed on the original table and the copy magnification. And the CPU 77
In ST20, a predetermined cassette that stores the paper of the determined size is set as the paper feeding place. Further, in ST21, the CPU 77 feeds a sheet from a predetermined cassette, operates the image forming unit to copy the image corresponding to the original image on the sheet, and then discharges the sheet to one bin. That is, the CPU 77 controls so that an image is placed on a non-copied sheet and the sheet is ejected.

On the other hand, when the empty sensor of the ADF is off, that is, when the replacement page is a copied sheet, the CPU 77 causes the sheet sensor 45a of the manual feed feeder.
Is turned on, that is, after it is detected that a copied sheet to be replaced in the manual feeder is inserted, the paper feeding place is set to the manual feeder in ST22.

Then, in ST23, the copied sheet is fed from the manual feeder, passes through the image forming section without copying the image, and is discharged to one bin. That is, the CPU 77 controls so as to discharge the copied paper without placing the image on it.

Next, if the number of copies is not 0 in STC, the CPU 77 sets the paper feed place to the temporary stacking unit in ST8, and discharges the copied paper into one bin.
When the number of copies = 0 in STC, C
The PU 77 counts down the BUSU data in ST14, and further controls to move the sorter downwardly by one stage in ST15 so that the two bins serve as a paper discharge tray.

Then, the CPU 77 repeats the above-described control until BUSU = 0 in ST16. As described above, the addition of pages and the replacement of pages, which have been difficult by the operator's manual work, can be automatically executed by using this image forming apparatus. Therefore, the burden on the operator can be reduced. Further, it is possible to prevent a work error caused by a manual operation of the operator.

The present invention is not limited to the above-described embodiment, but can be variously modified. For example, it is possible to execute both functions at the same time by continuously setting the page replacement mode and the page addition mode.

Further, in the page addition mode and the page replacement mode, the number of pages that can be added and the number of pages that can be replaced may be a plurality of copies and a plurality of pages.

Furthermore, in the above-described embodiment, only one-sided copying is handled, but double-sided copying is also possible. It is also possible to mix both-sided copying and one-sided copying.

Furthermore, the case where the LCC is used as a cassette for storing a series of copied sheets has been described, but another cassette may be used. Further, the place for storing the copied sheets corresponding to the additional page and the replacement page is not limited to the manual feeder.

Furthermore, the page deletion mode can also be realized if the same process as in the replacement mode is not performed and a new replacement page is not inserted. The present invention is not limited to the above-mentioned analog copying apparatus, but can be applied to other image forming apparatuses such as digital copying machines.
