2. Description of the Related Art In a conventional image forming system, a copying machine main body, a circulation type automatic document feeder (RDH) mounted on a contact glass of the copying machine main body, and a reciprocating automatic document feeder (RDH) are arranged on the side of the copying machine main body. A known finisher (FIN) is known.

[0003]

The above-mentioned conventional image forming system is composed of the copying machine main body, the RDH and the FIN system. However, when copying a plurality of CF originals, they are arranged in order of pages according to the number of copies. Since it could not be stacked on the discharge tray, the work of sorting the pages in order after copying remained, which was troublesome. In general, CF originals often have a large number of pages, and the sorting work is very troublesome.

By the way, the copying machine main body, RDH and FIN
An image forming system including
There is one reported in Japanese Patent Laid-Open No. 2-196677, but here, there is an advantage that a stapling original (block or the like) can be arbitrarily stippled in the second stippling mode. However, in this conventional image forming system, since it is not possible to align a plurality of copies in the SADF mode in page order for each copy, and staple them,
After copying, it was necessary to arrange them in page order, and to make them stipple, and to copy and make them stipple one by one, which was very troublesome.

Therefore, according to the present invention, a FIN stipple tray and a double-sided copy tray of the main body can be used to stack a plurality of copies of CF originals in page order, and the sorting operation is not performed in page order. In addition to the above, it is possible to automatically copy multiple copies arranged in page order in the SADF mode with a single copy operation, and to provide an image forming system that does not need to copy each part and stipple it. The purpose is to do.

DH) has a document feeding function of circulating a sheet document by the number of copies, and as an additional function, a computer sheet which is folded in a Z-fold and continuously connected is C
The F document has a function of being intermittently conveyed on the contact glass by a predetermined length (CFF mode), and the finisher has a paper binding function (stipple mode) and a stack function. It is a thing.

According to the first aspect of the present invention, when two copies are made in the CFF mode, the same number of pages as the storable number of sheets in the stapler tray of the finisher are aligned in the page order, and the sheets are automatically separated to form a two-sheet discharge tray. The CF document may be stacked up to the last page by repeating this operation in sequence.
When making copies, the finisher's stipple tray holds the same number of pages as the maximum number of pages that can be stored in the duplexer and the main unit double-sided copy tray. This operation may be repeated in sequence to process the CF original up to the final page. Furthermore, when copying four or more copies in the CFF mode, a stock tray other than the above can be used. You may. In these cases, it is possible to increase the number of page breaks to be aligned in the page order as much as possible, so that it is possible to easily stack and align all pages later for each number of copies, and reduce the copying and post-processing time. It is possible and preferable.

In addition to the configuration of the invention described in claim 1, the invention described in claim 2 can be used as a stock tray for simply aligning and storing the staple trays when a plurality of copies are made in the CFF mode. It is characterized by being configured into. In addition to the configuration of the invention according to claim 1, the invention according to claim 3 is configured such that when copying a plurality of copies in the CFF mode, both sides of the copying machine main body and a composite copy tray can be used as a simple stock tray. It is characterized by doing.

First, in the invention according to claim 1, for example, C
A case where two copies are made in the FF mode (P number of sheets that can be stored in the staple tray) will be described. Make two consecutive copies of one page of the CF original. The first sheet is discharged directly to the FIN discharge tray, and the second sheet is stored in the staple tray.
After this operation is continued for P pages, the temporary copy operation is stopped. During this time, a bundle of P pages aligned in page order in the stipple tray is discharged all at once by the discharge belt with the claws and stacked on the discharge tray. As a result, two copies of P pages of copy paper arranged in page order are stacked on the discharge tray. After that, the copy operation is restarted and P +
Copying of 1 to 2P pages is performed, the above operation is performed, and two sets of paper bundles arranged in page order are stacked. The above operation is repeated until the last page of the CF document is processed.

Further, for example, a case of making three copies in the CFF mode (the number of stippable storage P, the number of double-sided copy tray storage P _a , and P> P _a ) will be described. Make three consecutive copies of one page of the CF original. The first sheet is directly discharged to the FIN discharge tray, the second sheet is stored in the staple tray, and the third sheet is stored in the double-sided copy tray. After this operation is continued for _Pa pages, the temporary copy operation is stopped. In the meantime, as in the case of copying the above-mentioned two copies, the sheet bundle in the stipple tray is discharged onto the discharge tray and stacked, and then the sheets stored in the double-sided copy tray are discharged one by one in the order of page discharge tray. Transport to the top. Now, P _a aligned in page order on the output tray
This means that three copies of copy paper for pages have been stacked. Then, the same procedure is processed up to the final page.

If you want to copy more than 3 copies,
The above-described copy operation processing may be repeated twice or three times. As described above, according to the first aspect of the present invention, since the FIN stipple tray and the double-sided copy tray of the main body are used so that the copying operation and the stacking operation can be repeated, a plurality of copies of the CF document are arranged in page order. It is possible to load, and it is not necessary to sort the pages in order after copying.

According to the second aspect of the invention, since the FIN stipple tray is used, the same effect as that of the first aspect of the invention can be obtained. According to the third aspect of the invention, since the double-sided (composite) copying stock tray of the main body is used, the same effect as that of the first aspect of the invention can be obtained. Next, in the invention according to claim 4, a case where, for example, two copies are made in the SADF mode will be described.

Two copies are made for each original document.
The first sheet is stored in the FIN stipple tray, and the second sheet is stored in the double-sided copy tray of the copying machine body. The original is then continued to the last page P _n . A double-sided copy tray, in which one copy of P ₁ , P ₂ , and P _n is aligned and stored in the stipple tray, is stored in the same manner. Here, by depressing the manual stipple gold port, the copy paper bundle stored in the stipple tray is stapled, and is discharged onto the paper discharge tray by the claw-shaped discharge belt. After that, the copy paper bundle in the double-sided copy tray is re-fed one sheet at a time and stored in the staple tray. When the storage is completed, the staples are automatically stapled without pressing the manual aperture, and the sheets are ejected onto the paper ejection tray in the same manner as the first copy.

As described above, according to the fourth aspect of the invention, since at least a part of the stock tray including the stipple tray is used, a plurality of copies arranged in page order in the SADF mode are automatically performed by one copy operation. It is possible to do so without copying each copy and stippling. In the invention according to claim 5, since the double-sided (composite) copy tray can be used as a mere stock tray, it is preferable that two copies can be stapled in the SADF mode.

According to the sixth aspect of the invention, since the manual stapling hole is provided so that the stippling operation can be performed, the stapling is performed after the final sheet is surely stored in the stipple tray so that page leakage does not occur when stapling. can do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a schematic view showing the arrangement of an image forming system according to the first embodiment of the present invention. First, the conveyance of a CF document will be described with reference to FIG.

FIG. 1 shows a state in which a bundle of CF originals 502 placed on the upper cover of the FIN 501 is conveyed by the RDH 200 and is stored in the CF original storage box 300 while being folded. This CF document 502 is RDH
The CF document 502 is conveyed by a well-known technique such as a 200 conveyance belt (not shown), and the number of round holes at both ends of the CF document 502 is counted by a light transmission type sensor (not shown), so that a motor such as a motor not shown is The drive source is controlled so that it is intermittently conveyed by a constant length.

Next, the flow of copy paper will be described. First, when the print key is turned on, the copy sheets 503 are fed one by one from the sheet feeding unit 102 of the copying machine 100. Next, the copy sheet 503 is transported by being regulated by guide plates or the like provided above and below the transport path by rollers or the like. This is similar to a commonly known copying machine.
Next, the image is transferred onto the copy sheet 503 by the photosensitive drum 103, and is conveyed to the fixing roller 105 via the belt conveying section 104. In this way, the fixed copy paper 503 is
Since the reversal switching claw 106 has been switched to the solid line position in advance, it is guided to the reversal storage unit 107, and then the reversal roller 108 is moved to the broken line position by a solenoid or the like not shown, so that the copy sheet 503 is reversed and sent out. Be done. Next, since the double-sided switching claw 109 is in the solid line position in advance, the inverted copy sheet 503 reaches the main body discharge roller 110 and is sent to the FIN 501. Next, when the mode is further fed by the entrance roller 33 and the mode is the stack mode, the mode switching claw 5 is switched to the position of the broken line in advance,
The copy paper 503 passes through the conveyance path A, and the FIN discharge roller 34
Is discharged onto the discharge tray 6. On the other hand, in the staple mode, since the mode switching claw 5 is in the solid line position, the copy sheet 503 is stored in the staple tray 50 via the conveyance path B. Next, when a predetermined number of sheets are stored, the lower end portion of the bundle of copy sheets 503 is bound by the stapler 1, and the bound copy sheet 503 bundle is bound by the discharge claws 30 fastened to the discharge belt 3 to the lower end portion of the bundle of 7 sheets. Is lifted up and moved diagonally upward. Then, when the discharge belt 3 starts to rotate, the discharge upper guide plate 71 to which the discharge driven rollers 36 are attached is moved to the position of the broken line almost at the same time (see FIG. 2), and the sensor S3 detects the leading edge of the sheet bundle and the FIN. When the front end of the paper discharge roller 34 is reached, the paper discharge upper guide plate 71 is returned to the position indicated by the solid line. As a result, a conveying force is applied to the sheet bundle and the sheet bundle is discharged onto the sheet discharge tray 6.

Next, FIG. 2 is an enlarged side view of the vicinity of the stack portion I shown in FIG. The vertical movement of the discharge tray will be described with reference to FIG. A support bracket 70, which supports a rotatable sponge roller 35 at one end, is rotatably attached to an edge of the recording paper discharge side of the discharge tray 6, and the vertical movement of the sponge roller 35 causes the sponge roller 35 to move near the other end. The height of the uppermost surface of the discharged recording paper is detected by the attached paper surface detection sensor S4, and a control signal for controlling the vertical position on the paper discharge tray 6 is issued. That is, a certain amount of recording paper
When the uppermost sheet of paper piles up the sponge roller 35 and the approach of the other end of the support bracket 70 is detected by the sheet surface detection sensor S4, the vertical movement motor is driven by the detected detection signal, and the sheet surface detection sensor is detected. The paper discharge tray 6 is lowered until S4 no longer detects one end of the support bracket 70. In this way, the position of the paper discharge tray 6 is kept substantially constant with respect to the paper discharge roller 34, and a smooth stacking operation is ensured.

Next, a description will be given of how to copy sheets when a plurality of copies are made in the CFF mode, for example, when three copies are made in the CFF mode. For example, the number of stipples that can be stored is 50, and the number of double-sided copy trays that can be stored is 40
The case of one sheet. First, as the first copy operation,
Three copies of one page of the CF document are continuously taken, 40 pages are taken, and the copy operation is temporarily stopped. Then, the copy sheets taken every three sheets are conveyed as shown in FIG. When ejecting from the stipple tray, it is ejected without stipple. When re-feeding from the double-sided copy tray, the sheets are fed one by one from the bottom side, and the FIN is not transferred on the photosensitive drum.
Empty the paper to the paper output tray. With the above operation, CF original
This means that 40 pages are aligned in the order of 3 pages and stacked on the output tray.

As described above, in the present embodiment, the CF document can be copied up to the final page by repeating the copy operation and the stacking operation, and the CF originals can be stacked in page order by 40 pages. (Second Embodiment) FIG. 4 is a schematic view showing the arrangement of an image forming system according to the second embodiment of the present invention. First, the SADF of RDH will be described with reference to FIG.

First, the documents are placed one by one on the SADF document table 202 and inserted into the SADF document input port 201, whereby the sensor 21 detects the leading edge of the document,
The entire system can be switched to SADF mode. Then, after switching to the SADF mode, it is conveyed onto the contact glass 401 by a known technique such as a roller and a belt (not shown) and temporarily stopped. Then, during this time, the image of the original is formed as a latent image on the photosensitive drum 103 by the desired number of copies by using a known optical technique not shown. After that, the document is further conveyed, and the document is discharged onto the document discharge tray 112. The above operation is repeated until the original is exhausted.

Here, the flow of copy paper and the vertical movement of the paper discharge tray are the same as those in the first embodiment, so description thereof will be omitted. Next, a description will be given of how to copy sheets when two copies are made in the SADF mode and the sheets are arranged in page order and stapled. For example, the maximum number of staples that can be
With 50 sheets, the number of sheets that can be copied on both sides is 40. Manuscript 1
Make 2 copies each. Next, the copy sheets taken two by two are conveyed as shown in FIG. 5 (the staple mode is selected).

For re-feeding from the double-sided copy tray, the sheets are fed one by one from the bottom, and the FI is not transferred on the photosensitive drum.
It is fed to the N staple tray. Then, after all the originals have been copied, a manual stipple gold mouth 113 is newly arranged in the operation gold mouth group of the copying machine. The sheet bundle stored in the tray is stapled and discharged onto the discharge tray by the discharge belt 3. Next, the copy sheets stored in the double-sided copy tray are automatically re-fed one by one and guided into the stipple tray as shown in FIG. Next, after the final paper is stored in the stipple tray, it is stapled, and the recognition that it is the final paper discharged by the discharge belt is made by storing the number of sheets in advance in the sensor S2 when the staple is made in the first time. Every time, the final number of sheets is reached when the number of sheets reaches the same number. Further, the manual stylus ferrule 113 can be used only in the SADF mode. This is to prevent erroneous operation. Moreover, there is a time lag so that the first stipple operation is performed after several seconds have passed even when the gold port 113 is pushed, and that the final paper is surely stored in the stipple tray and then stapled.

According to this example, up to 40 originals can be processed. Then, after the copying of 40 originals is completed, the operator is warned by the panel display that the number of processed originals is exceeded. Then, when it is desired to staple the operator, the manual stipple gold port 113 is pushed. On the other hand, if you do not want to use stipple, switch the mode from stipple mode to stack mode.

Next, when stapling is desired, the manual stapling gold port 113 is pushed, stapling is carried out by the above-mentioned operation procedure, and two sets are stacked on the paper discharge tray. on the other hand,
When the user does not want to staple, the stack mode gold port 115 is pushed down, and the sheet bundle stored in the stipple tray is not stapled but is ejected onto the ejection tray at once by the ejection belt. Then, the sheet bundle stored in the double-sided copy tray is re-fed one by one, the mode switching claw 5 is switched to the position of the broken line, and the sheets are stacked one by one in the page order on the sheet ejection tray via the conveyance path A. .. The copying operation is completed by performing the same procedure for the 41st and subsequent pages of the document.

[0031]

As described above, according to the present invention, a plurality of copies of CF originals can be stacked in the page order and stacked, and it is not necessary to sort the pages in the page order after copying, and in the SADF mode, the pages are arranged in the page order. Multiple copies can be made automatically with a single copy operation. 1
There is an effect that it is possible to make copies without copying and to prevent stippling.
