Moreover, the peripheral speed of the sponge roller 51.51 is 47.
It is desirable that the speed be slightly faster than the circumferential speed of 48. Further, a plurality of pairs of sponge rollers 51, 51 may be provided depending on the size of the paper P.

Inside the casing 44 on the downstream side of the conveyance roller 55, 55 is a shaft 56a extending between the solid line position and the chain line position in FIG.
Non-binding trays 1 to 56 that can be rotated around are arranged, and the non-binding tray 56 receives unfolded sheets P that do not need to be bound from the paper folding section 45 at the chain line position. Furthermore, when the sheets P to be bound are conveyed from the sheet folding section 45, they are moved to the solid line "9" and "141" and then evacuated.

A paper binding section 57 is provided in the casing 44 below the non-binding tray 56.

This paper binding part b7 is arranged so that it can be raised and lowered, and

The surface 60 is formed into an acute edge shape so that the folds of the sheets P folded at the center by the sheet folding section 45 are aligned and the sheets P are stacked one on top of the other. Further, on both sides of the five U-seats, a pair of flat guide plates 63,64 which are rotatable (supported by two) by spindles 61,62 are disposed near the receiving surfaces 60 of the five U-seats, respectively. Each of the guide plates 63 and 64 is movable between the solid line position and the chain line position in FIG.

A fixed wall plate 65 is erected on one side of one of the guide plates 64, as shown in FIG. A wall plate 66 is erected and is movable in a direction perpendicular to the axial direction of 62. This configuration is achieved by forming the base of the wall plate 66 and the guide plate 64 into a comb-like shape that interlocks with each other. Furthermore, the paper P on the guide plate 64 is transferred to the outside of the wall plate 65 in pressure contact with the paper P, and the two adjacent sides of the paper P are placed on both wall plates 65.

Bookbinding consisting of the aforementioned paper folding section 45 and paper binding section 57! ! Regarding saddle stitch binding of paper P by ibuy46'C
I'll explain.

The paper P conveyed from the fixing section 34 to the paper binding section 57
The tip of the paper P passes through the L conveyance rollers 47, 48 and the sponge rollers 51 and 51, and comes into contact with the strike collar 54, which has been arranged in advance to match the four noises of this paper P, and stops. Although the sponge rollers 51 and 51 continue to rotate, their conveying force is weak, so there is no risk that the paper P will buckle.

Then, the paper P by the subsequent conveyance roller 47.4.8
As the paper P is being conveyed, it begins to warp near the end of the path 50. At this time, the timing is determined based on the signal from the sensor 53 that detects the paper P, and the missing circumference [the paper 1 that is bent due to one rotation of the cola 49] is caught between the conveyance roller 47 and the O-949, and the center of the paper P is Form a crease in the section. Thereafter, the notched part of the notched part 11-49 faces the conveying roller 47, but before this state is reached, the stopper 54 closes the passage 52.
Since it is retracted from the 0-
When the conveying force is lost facing the roller 47, the sponge roller 5
Paper P with a crease formed in the center by a conveying force of 1°51
is transport roller 5! : +, supplied to the sheet binding section 57 from the 55 direction.

When paper P with a crease formed in the center is supplied, both guide plates 63 and 64 of the paper binding section 57 are arranged so that the leading end of the guide plate 64 is positioned slightly downward, as shown by the solid line in FIG. are located in the same plane and are inclined. Note that, at this time, the non-binding tray 56 is located at the solid line position in FIG.

In this state, the sheets P fed onto both guide plates 63 and 64 are moved one by one by the action of odd-width zero rollers 67 to both wall plates 63 and 64.
5 and 66. In this way, all the paper sheets P constituting one booklet are placed on both guide plates 6.
3.64, the wall plate 66 is moved in the direction of the support shaft 6273, and the paper P is moved so that the fold of the paper P is positioned over the edge of the receiving seat 59.

Then, rotate both the guide plates 63 and 64 to the positions shown in chain lines in FIG. The alignment μ is tightened, and the binding tool 58 is fixed to the fold of the paper P to bind the paper P.Finally, by rotating one guide plate 63 to the solid line position and retracting the wall plate 66. The saddle-stitched paper P is along the guide plate 64 -C
It slides down and is collected in the tray 68.

Saddle stitch binding can be performed as described above using the recirculating original handling device 4, copying device 25, and bookbinding device 46 described above. Note that for saddle stitching, it is necessary to always consider the order n of the originals to be copied onto the paper P, so the copying order and the like will be explained below.

Figure 6 shows a state in which a 20-page manuscript is duplicated onto five sheets of paper P and saddle-stitched; the first page of the manuscript,
Pages 2, 19, and 20 will be copied onto one sheet of paper P, and the 8th page of the manuscript that will be copied onto the other four sheets of paper 1 will also follow this relationship. It has become.

Ma IC and saddle stitch binding are classified into vertical writing and horizontal writing, with vertical writing being right edge binding and horizontal writing being left edge binding. Furthermore, the front right of the cover, etc. f8? ! Classification can also be done based on two copies or variable size copies.

Next, let's take a look at the original when performing Nakadoji bookbinding with full-size copies! IS
Combinations of D and paper P are accepted as follows - J: Unaru, 1st) When the paper size is twice the original size, vertical feeding means that the short side of the original paper or paper P is in the transport direction. Transverse feeding refers to the case where the long side of the original 1 [) or paper P is made perpendicular to the conveying direction.

A combination of the tables described above is shown in FIG.

■) If the paper size is the same as the original size Table 2 This combination is illustrated in FIG.

Further, Table 3 shows the combinations of manuscripts and sheets P and the variable magnification ratios when saddle stitching is performed by variable magnification copying. .

Table 3 In this case, the same applies when the document is double-sided.

This is illustrated in FIG. 9.

Table 4 summarizes the conveyance direction of the manuscript and paper P in the case of saddle stitching as described above.

Table 4 Next, considering the number of pages on the manuscript paper and paper P, in general, when the number of single-sided manuscripts is n, the total number of manuscript pages is n.When the number of double-sided manuscripts is n, the total number of manuscript pages is The number of pages is 20, but in the case of saddle stitching, depending on the combination of original paper and paper P, this may not be the case.

In other words, in saddle stitching, the center of the long side of paper P is
The folded size, that is, the half size of the paper P corresponds to one page of the paper P, and the document information copied onto one page of the paper corresponds to one page of the document.

For example, as an example of full-size copying, an A3 single-sided document with vertical feeding
When the sheets are saddle-stitched onto vertically fed A3 paper, one page of the paper P and one page of the manuscript are A4 size, so the total number of manuscript pages is 2m pages.

Even when variable-magnification copying is performed at the variable magnification ratio described above and saddle stitching is performed, the original size that is copied to half the size of the paper P is equivalent to one page of the original.

When saddle-stitching n pages of manuscripts, the total number of pages of manuscripts depending on the combination of manuscripts and paper P can be summarized as follows according to the table of magnification ratios mentioned above. become.

i) Box 5 for n sheets of single-sided Ii5'I manuscripts Table 11) The number of cases for n sheets of double-sided manuscripts and which page will be the innermost sheet P of the saddle-stitched book are extremely important, but To calculate the required number of sheets, you must calculate the total number of pages in the manuscript, and also the number of sheets in the manuscript. There are two possible methods for this: (i>The operator inputs 1@the number of manuscripts, and (11) the @number of manuscripts is automatically input.

Among these, according to the automatic input method, the number of originals is automatically input by counting the number of originals by feeding the original by a recirculating original handling device using a recirculation type original handling device.

In this way, when the number of manuscripts n is reached, Tables 5 and 6
The total number of original sheets is determined by the combination of original sheets and paper P during saddle stitch binding shown in the table. And Konohara 1
When the total number of pages of iD is N, the required number I of sheets P is given by the following equation.

However, N and I are positive integers.

With this, the required number of sheets of paper P corresponding to the total number of pages of the manuscript is I.
Having been determined, the next question is how many pages of the original mD are to be copied onto which paper P.

Considering an integer i such that Q<i≦1, the page device of paper i from the i-th paper P is as follows.

i) In the case of a horizontally written original, as shown in Figure 10, write 21-1 on one side of one sheet of paper 1.
While copying page J-, page 21 must be copied on the back side, and page 41-2i+2 must be copied on the other side of sheet 1, and page 41-2i+1 must be copied on the back side.

ii) In the case of a vertically written manuscript, as shown in Figure 11, 4l-2 on one side of one sheet of paper
When copying page i+2, 4r-2*+i is printed on the back of this page.
You must copy pages 21-1 on the other side of the page 1i, and copy page 21 on the back of this.

As is clear from this, the copy positions are symmetrical between horizontal writing and vertical writing.

Now that we have decided on the combination of original paper and paper P, the required number of paper P, the page device for paper P, etc. for saddle stitching, we will move on to the original paper and paper P for saddle stitching. Consider the movement of -C.

As described above, the recirculating document handling device 4 of the present invention has the function of being able to move on to copying on the next document tray after completing copying on both sides of the document tray 6 fed from the document tray 6. Therefore, during saddle stitching, the original 1] can be processed in a short time, and the pages of the original can be aligned even after copying is completed.

In order to explain the operation of a manuscript for saddle-stitching using such a recirculating manuscript handling device 4, 10 sheets of an old double-sided manuscript with a page order of Δ4 are copied onto both sides of 5 sheets of 83 paper. Consider the case of saddle-stitch binding.

To simplify the following explanation, as shown in Figure 12, manuscript 1: 1 page on the front, 2 pages on the back.Manuscript 2: 3 pages on the front, 4 pages on the back.Manuscript 3: 5 pages on the front. , 6 pages on the back Original 4: 7 pages on the front, 8 pages on the back Original 5: 9 pages on the front, 10 pages on the back Original 6: 11 pages on the front, 12 pages on the back Original 7: 13 pages on the front, 12 pages on the back Original 8: 15 pages on the front and 16 pages on the back Original 9: 17 pages on the front and 18 pages on the back Original 10: 19 pages on the front and 20 pages on the back.

At this time, the pages of the five A3 sheets are as shown in FIG.
:Manuscript page 3, page 4, page 17, page 18 Paper 3: Manuscript 5
Pages, 6 pages, 15 pages, 16 pages Paper 4: Manuscript pages 7, 8,
13 pages, 14 pages Paper 5: Manuscript pages 9, 10, 11,
Four pages of each manuscript, such as 12 pages, are copied.

According to the re-vlU circular document handling device 4,
In the pages of the manuscript, page 1 → page 2 → page 3 → page 4...17
Page → page 18 → page 19 → page 20, or page 2 → page 1 → 4
Page→3 pages...18 pages→17 pages->20 pages→19
It is also possible to copy in the order of pages, that is, original 1 -> original 2...original 9 → original 10, or in the order of 20 pages → 19 pages → 18 pages → 17 pages... 4 Page → 3 pages → 2
Page → 1 page, or 19 pages → 20 pages → 17 pages → 18 pages・
...It is also possible to copy in the order of page 3 → page 4 → page 1 → page 2, that is, in the order of manuscript 10 → manuscript 9 . . . manuscript 2 → draft 1.

Using such a recirculating type document handling device 4, we will explain the general movements of the document copying machine and the paper MP when copying 10 A4 horizontally written double-sided documents onto both sides of 5 sheets of A3 paper and saddle-stitching them into a book. .

First, regarding the document tray, ten document sheets are placed in order in the document tray 6 with the odd-numbered pages facing upward, the document 1 on the top, and the document 10 on the bottom. Then, the document in the document tray 6 is conveyed onto the contact glass 3 from the lower side, that is, the document 10, and the document 19 of the document 10 is transported onto the contact glass 3.
Immediately after the pages have been copied, the original 10 is turned over and 20 pages are copied again on the contact glass 3. pages 19, 20
After the pages have been copied, the original 10 is turned over and returned to the original 1 in the original tray 6 with page 19 facing upward. Similarly, pages 17 and 18 of manuscript 9, pages 15 and 16 of manuscript 8, pages 13 and 14 of manuscript 7, pages 11 and 1 of manuscript 6,
Page 2, pages 9 and 10 of manuscript 5, pages 7 and 8 of manuscript 4, pages 5 and 6 of manuscript 3, pages 3 and 4 of manuscript 2, pages 1 and 2c of manuscript 1 (in this order) Copy them and return them to the original tray 6.

In this way, the final set state of the original No. on the document tray 6 after all the originals have been copied is the same as the initial document let state, and the pages are arranged.

On the other hand, the movement of the paper P related to the movement of the document tray described above will be explained with reference to FIG.

First, the paper 1 is conveyed from the paper cullet 29 to the developing section 26 and is copied at 19. The paper 1 advances in the directions of arrows C and D, is reversed, and then moves in the direction of arrow E.

F, G, and B are conveyed in this order, and 20 pages are copied onto the 19th page. Thereafter, the paper 1 is transported in the direction of arrow H1E and temporarily stored in the intermediate tray 39.

Similarly, paper 2, paper 3, paper 4, and paper 5 are sequentially supplied from the paper cassette 29, and paper 2 has 17 pages and 1
8 pages, 15 pages and 16 pages on paper 3, 13 pages on paper 4,
Page 14, paper 5, is stored in 11@.

The order of the sheets P in this intermediate tray 39 is from -hanging to sheet 5, sheet 4, sheet 3, sheet 2, and sheet 1. Therefore, from this intermediate tray 39, the top paper 5
will be resupplied first. Then, this paper 5 is transferred to the developing section 2.
6 and when page 9 is copied, this paper 5 advances in the direction of arrow C9D and copies page 10. This means that pages 9, 10, 11, and 12 of the paper 5 have been copied, and the paper 5 is conveyed to the paper folding section 45.

Similarly, paper 4 has pages 7 and 8, paper 3 has page 5,
6 pages, 3 pages on paper 2, 4 pages, &311 pages on paper 1, 2
The pages are copied and sequentially conveyed to the paper folding section 45.

Note that when the paper P is again supplied to the developing section 26 as shown by arrows E and F, it is not necessarily necessary to avoid passing through the intermediate tray 39, and it may be made to pass through another path.

As mentioned above, unless you use the recirculating manuscript handling device 4, you will have to use the recirculating manuscript handling device 4.

1) There is no need to repeatedly feed and reverse the document tray in order to perform final page alignment on the document tray.

2) Compared to the conventional recirculating type document handling device that cannot continuously copy both sides of a single document tray, the number of times the document tray is circulated is less, resulting in problems such as damage to the document tray and jamming. In is low.

3) The number of times the paper P is fed from the intermediate tray 39 is reduced, and the reliability of the transport of the paper P is improved.

In the above-mentioned embodiment, the order of copying the manuscript is 19th page, 20th page, 17th page, 18th page, 3rd page, 4th page, etc.
Although the explanation was given in terms of page, 1 page, and 2 pages, if you invert each manuscript page before copying, the copy order can be changed to 20 pages.
Pages, 19 pages, 18 pages, 17 pages...4 pages, 3 pages,
It can also be 2 pages or 1 page.

Furthermore, if the first document is set in the document tray 6 of the recirculating document handling device 4 with the front side, that is, the odd-numbered pages facing down, the document 1 is placed on the bottom and the document 10 is placed on the top. Page, 2 pages, 3 pages, 4 pages...17 pages, 18 pages, 19 pages, 20 pages, or 2 pages, 1 page, 4 pages, 3 pages...
It is also possible to copy pages 18, 17, 20, and 19 in this order, that is, original 8i1, original 2, . . . original 9, and original 10 in this order.

The above describes the case where the paper size is twice the original size and the original is double-sided, when 10 A4 double-sided originals are saddle-stitched onto 5 A3 sheets using the recirculating manuscript handling device @4. Therefore, next, an example of saddle stitching in another mode will be explained.

First, as an example of a case where the paper size is twice the original size and is a single-sided original, consider the case where 20 sheets of A4 horizontally written single-sided originals are saddle-stitched into 5 sheets of A3 paper.

The originals are placed in the original tray 6 with the front side, that is, the side with information facing upward, with page 1 at the top and page 20 hanging down.

Then, since the originals are supplied to the contact glass 3 from the bottom of the original tray 6, pages 20, 19, 18
Page 17, . . . 4 pages, 3 pages, 2 pages, 1 page are copied in this order, and the originals are returned to the original tray 6 in order. Therefore, the final document hit state is the same as the initial document set state, and the page order is the same.

The movement of the paper P at this time is summarized as follows.

1) Feed paper 1 from paper cassette 29 -> invert Copy 20 pages of circulation - > copy page 19 -> intermediate tray 39 2) Feed paper 2 from paper cassette 29 -> invert Copy 18 pages of circulation -> page 17 Copy → Intermediate tray 39 3) Feed paper 3 from paper cassette 29 → Reverse Circulate page 16 Copy → Copy page 15 → Intermediate tray 39 4) Feed paper 4 from paper cassette 29 → Reverse Circulate page 14 Copy - ÷ Copy 13 pages - Door intermediate tray 39 5) Feed paper 5 from paper cassette 29 → Reverse Copy 12 pages in circulation → Copy page 11 - → Intermediate tray 39 6) Feed paper 5 from paper cassette 39 Paper feed → Copy page 10 inverted → Copy page 9 → Paper tray 5 7) Feed paper 4 from paper cassette 39 - → Copy page 8 inverted -) Copy page 7 - Paper tray 5 8) Paper cassette・Feed paper 3 from paper cassette 39 → Copy page 6 inverted → Copy page 5 → Paper tray 5 9) Feed paper 2 from paper cassette 39 -> Copy page 4 inverted -) Copy page 3 → Paper tray 5 10) Feed paper 1 from the paper cassette 39 → Reverse it and copy page 2 → Copy page 1 → Paper tray 5 Also, place 20 pages on top with the side with information facing down, - hang Even if you place the manuscript paper in the original 1~Reiro so that page 1 is on page 1, the order of copying will be page 1, page 2, page 3,
4 pages... 17 pages, 18 pages, 19 pages, 20 pages, etc., can be saddle-stitched in the same manner as described above.

However, in this case, each document must be turned over once before being fed onto the contact glass 3.

Next, as an example of a case where the paper size is the same as the document size and the document is a double-sided document, consider a case in which five sheets of A3 horizontally written double-sided documents are saddle-stitched onto five sheets of A3 paper.

Manuscript 1: 1 page, 2 pages, 3 pages, 4 pages Manuscript 2: 5 pages, 6 pages, 7 pages, 8 pages Manuscript 3: 9? , 10 pages, 11 pages, 12 pages (manuscript 4:1
Pages 3, 14, 15, and 16 original manuscripts: pages 17, 18, 19, and 20, and as shown in Figure 15, the surface,
In other words, pages 1 and 2, pages 5 and 6, pages 9 and 10, pages 13 and 14, and pages 17 and 18 should be facing upwards, starting from the bottom: manuscript 5, manuscript 4, manuscript 3. , original 2, and original 1 are placed on the originals 1 to 1 in this order.

Then, the original 5 located at the most 1ζ in the original tray 6 is fed onto the contact glass 3, and the original 5, original 4, original 3, original 2, and original 1 are copied in this order.

In this case, the copying order for the saddle stitched book is 20 pages, 19 pages,
18 pages, 17 pages, 4 pages, 3 pages, 2 pages, 1 page, or 19 pages, 20 pages, 17 pages, 18 pages...
-3 pages, 4 pages, 1, 1.2 pages, etc. can be considered.

Therefore, first, the original 5 is fed onto the contact glass 3 to copy page 20, and then, while the original 5 remains stationary on the contact glass 3, page 19 is copied. When the copying of the 19th page is completed, the original 5 is reversed and the 18th page is copied, and then the 17th page is copied in that state. Now that all the copies of the original 5 have been completed, the original 5 is turned over again and placed on top of the original 1 in the original tray 6. Next, manuscript 4,
Original 3, original 2, and original 1 are sequentially fed onto the contact glass 3 and copied in the same manner as described above, and when the copying is completed, they are turned over again without returning to the original tray 6.

The original set on the original tray 6 after copying of the five original sheets is the same as the initial state shown in FIG. 15, and the pages are aligned. Note that when there are two pages of information on one side of one original sheet, and when performing the above-mentioned copying method of copying these individually, the electrostatic latent image of the unnecessary page is removed from the photoreceptor drum 281 by an erase means. do.

To explain the paper movement at this time, the paper cassette 29
When paper 1i is supplied from page 1 and page 20 is copied, sheet 1 is reversed and page 19 is copied on the back of page 20. after that,
This paper 1 is stored in the intermediate tray 39. Similarly, paper 2, paper 3, paper 4, and paper 5 are supplied from the paper cassette 29, and paper 2 has pages 18 and 17, and paper 3 has pages 1 and 5.
6 pages and 15 pages, paper 4 has 14 pages and 13 pages,
Pages 12 and 11 are each copied onto the paper 5 and stored in the intermediate tray 39. The state of the paper P in this intermediate tray 39 is shown in FIG.

Next, the paper 5 is first supplied from the intermediate tray 39 and
Page 0 is copied, then reversed and page 9 is copied. This means that the copying of pages 9, 10, 11, and 12 of the paper 5 has been completed, so the paper 5 is conveyed to the paper folding section 45.

Similarly, paper 4 has pages 8Q and 7, and paper 3 has pages 6 and 7.
pages and 5, pages 4 and 3 on paper 2, t on paper 1
2@ and 1 pages are each copied and sequentially conveyed to the paper folding section 45. FIG. 17 shows the stacked state of the sheets P on both guide plates 63 and 64 of the sheet binding section 57 after the folds have been formed in the sheet folding section 45. As is clear from this figure, the copy pages on each sheet 1] are ready to be bound into a book.

Next, as an example of a case where the paper size is the same as the original size and is a single-sided original, consider a case in which 10 A3 horizontally written single-sided originals are saddle-stitched into 5 A3 sheets.

As shown in Figure 18, page 1 and page 2 of the manuscript are placed on the top with the side with information facing upwards, and page 19 is placed on the hanging side.
Ten original sheets are placed in the original tray 6 so that the originals of page 20 and 20 are in the same position.

The document feeder is supplied from the bottom.Cl2O page, page 19, 1
8 pages, 17 pages...4 pages, 3 negative pages, 2 pages, 1 page, or 19 pages, 20 pages, 17 pages, 18 pages...
Pages 3, 4, 1, and 2 are copied in this order, and the originals are returned to the original set 6 in order. The final document tray condition is the same as the initial document set, and the page order is the same.

The movement of the paper P at this time is summarized as follows.

1) Feed paper 1 from paper cassette 29 → Reverse Copy 20 pages of circulation → Copy 19rA → Intermediate tray 39 2) Feed paper 2 from paper cassette 29 - Invert Copy 18 pages of circulation -> Page 17 Copy → Intermediate tray 39 3) Feed paper 3 from paper cassette 29 → Reverse Circulate page 16 → Copy page 15 - → Intermediate tray 39 4) Feed paper 4 from paper cullet 29 → Reverse Circulate page 14 Copy → Copy page 13 → Intermediate tray 39 5) Feed paper 5 from paper cassette 29 → Reverse Copy circulating page 12 → Copy page 11 → Intermediate mill lay 39 6) Feed paper 5 from intermediate tray 39 → Reversal Copy circulating page 10 → Copy page 9 → Paper folding unit 5 7) Feed paper 4 from intermediate tray 39 → Reverse 8 Copy circulating page → Copy page 7 → Paper folding unit 5 8) From intermediate tray 39 Feeding paper 3 → Reversing 6 Copying the circulating page → Copying page 5 → Paper folding unit 5 9) Feeding paper 2 from the intermediate tray 39 → Reversing 4 Copying the circulating page → Copying page 3 → Paper folding unit 5 10) Feed paper 1 from intermediate tray 39 → Reverse 2 Copy circulating pages → Copy page 1 - Child paper folding section 5 Above, all original sheets and paper P when performing saddle stitching with same-size copying. In the combination of (manuscripts and paper P)
This explains the movement of the page, that is, the method of page bias. It should be noted that the same applies to the case of variable size copying, so the explanation will be omitted. Note that the magnification ratio at the time of magnification/multiplication η is determined by the document size, paper size, and document placement direction.

Next, a modified example of saddle stitching will be explained.

Saddle stitch binding when the original size and the paper size are the same as described above is performed when the original information is separated in the center and the left and right original information is simultaneously stored. In this case, the left and right information on the original document will be copied on the front and back sides of the bound paper P.

However, for example, large tables, graphs, etc.
If the table, graph, etc. is drawn across the left and right pages of D, it is inappropriate to cut and copy the table, graph, etc. Therefore, in such a case, unlike saddle-stitch binding in which the left and right manuscript information can be separated, for example, the manuscript is copied on page 2 of paper P instead of copying on page 1 of paper P. Copy page 1 of
When copying pages, if you do not copy the first odd-numbered page of paper P and copy one page of the manuscript from the next even-numbered page, when the saddle-stitched paper P is opened, the manuscript will be You can view information on the left and right sides of the screen at the same time.

In this case, the first odd-numbered pages of paper P are not copied, and one page of the manuscript is copied from the even-numbered page of paper P. Therefore, if the number of odd-numbered pages that are not copied is n, the appearance is The number of pages of the Shibu manuscript is N+n.

Therefore, the required number of sheets of paper P is an integer I that satisfies the above equation (1).

When copying is not performed on the first page of paper P, the page device of paper P is as shown in FIG. 19.

Next, if the information on the left and right sides of the manuscript can be divided, saddle stitching can be performed so that either the left or right page will be blank when viewing. This blank page can be used for notes or to add information later, and it will be even easier to use if you write down lines, eyes, etc. In this case, the first page and last page of paper P are not copied.

The number of MP sheets required for such one-sided blank mode is:
Letting the total number of pages of the manuscript be N, it becomes an integer I that satisfies .

When a cover is required in the various saddle stitching modes described above, a sheet of paper to be a cover is set in one of the three paper cassettes 29.

Regarding the cover, there are cases in which a copy is made on the cover and cases in which a copy is not made on the cover.

When copying on the cover, the cover may be considered as part of the paper, and when copying is not on the cover, the paper that will become the cover may simply be supplied to the paper folding section 45.

In addition, you can use regular paper P without preparing a new paper for the cover.
may be used for the cover, or separate sheets of paper of different colors and thicknesses or sheets with fixed text may be prepared.

In the above explanation, the case where the original paper is written horizontally has been described, but next, the case where the original paper is written vertically will be described.

If the manuscript is written horizontally or vertically, when the first page of the paper P is facing up, the binding section will be on the left edge, whereas in the case of IS writing, when the first page of the paper P is facing up, the binding section will be the left edge. is on the right end.

The following two methods can be considered for saddle-stitching a vertically written original whose characteristics are different from those of a horizontally written original.

(i) The initial set of originals is the same as for horizontally written originals, and the transfer position onto paper P, that is, the way of page editing, is changed.

(ii) The first set of originals is turned upside down and the transfer position onto the paper P is the same as in the case of a horizontally woven original.

The required number I of sheets P for this vertically written original is given by the above-mentioned equation (1), as in the case of a horizontally written original.

The saddle stitch binding method in the case of (+) described above is as shown in FIG. In other words, the page device for the first sheet of paper P is 41-2 on the negative side and 4■-21+1 on the back of the +2 page.
The page will be copied, and on the other side, page 21 will be copied on the back of page 21-1.

At this time, the movement of the document and the paper P can be determined by reversing the transfer position on the paper P from left to right with respect to the page arrangement of the horizontally written manuscript shown in FIG.

In the case of (ii) mentioned above, saddle stitching of the single-written manuscript can be done by simply flipping the horizontally written manuscript set shown in Figure 20a upside down, as shown in Figure 20. It becomes possible. At this time, the page device of the paper P is the same as in the case of a landscape original.

Next, I will explain the binding margin when binding books with saddle stitching.
In saddle-stitch binding, when the size of the document sheet and the paper P are the same, information on the right half of the document sheet must be copied separately, and therefore information on the center portion of the document sheet may be missing.

In order to eliminate this inconvenience, the information near the center of the original ID may be copied so as to be included on both the left and right pages of the sheet P.

For example, if the image is reduced by 99% during image creation, the central portion of an A3 document will overlap by about 2 mm.

If you follow the above-mentioned capacity, you can efficiently edit the pages of a saddle-stitched book, but it takes time when binding multiple copies, and the number of times the manuscript is circulated increases. Easy to store.

Therefore, by performing only the saddle stitching editing of the paper P according to the above-mentioned page editing, etc., and ejecting the paper P without performing center folding or saddle stitching, this ejected paper P can be used as a new manuscript I]. Then, it becomes possible to copy both the left and right pages of this new original document at the same time, increasing the bookbinding speed.

〔Effect of the invention〕

As explained above, the copying machine equipped with the bookbinding function according to the present invention has a reversing section adjacent to the contact glass, exposes both sides of the original from the original tray as necessary, and then returns the original to the original tray. a recirculating document handling device configured to do so; a reversing section for reversing sheets that have already been copied on one side; and an intermediate tray for temporarily storing sheets that have already been copied on one side in preparation for copying on the reverse side thereof; a copying device; a bookbinding device comprising: a paper folding section that is connected to the conveyance path of the copying device for forming a crease in the center of the paper; and a paper binding section that is provided in the paper folding section; Since the present invention has the equipment, an excellent effect is achieved in that saddle stitching of vertically written originals and horizontally written originals can be performed without making any complicated movements of the original and the paper. In addition,
It goes without saying that edge binding or no binding can be performed.
