Abstract

PURPOSE:To make one of a double-spread blank by sectioning a form into four top and reverse, and right and left areas, specifying pages of originals in two of four areas of plural forms and taking a copy, and folding the forms into two and making saddle stitching. CONSTITUTION:Originals are sent out of an original tray 6 in specified order onto a contact glass surface 3 with the top up and down and copied by a copying machine 25. The copying machine 25 transfers an image which is developed 26 on a photosensitive body 26 to forms P from a form cassette 29, and the image is fixed 34. The top and reverse, and right and left of the forms P are specified during transfer so that a half of double page spread is blank in conformity with the page order of the originals when the forms P are folded by a two-folding part 45 and stitched togethr by a stitching tool 58. For the purpose, the forms P select various routes of an intermediate tray 39 and an inverting part 35. For example, the left half of the reverse of the (N)th form P, and the top right half and left reverse half parts of the (N+1)th form are copied in order. Thus, saddle stitching edition is performed efficiently so that the right side of a double-spread is blank.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a bookbinding copying method for copying a manuscript onto paper and then saddle-stitching the manuscript.

〔Technical field〕

The present invention relates to a copying machine capable of double-sided copying, and particularly to a copying machine equipped with a bookbinding function.

(Prior Art) Conventionally, when copying multiple copies of multiple sheets of original, a sorter or collating device is used to align the page order of the copied sheets, and a stitcher or the like is used to stitch the edges of the sheets. The binding was being done.

However, when large-sized sheets such as A3 and B4 are end-stitched, they take up a large amount of space when spread between two pages, making them difficult to handle. In addition, in the case of large 4-noise paper, the edge-stitched paper is sometimes folded in half at the center to reduce the space required for storage. It looks bad, and the folding makes it difficult to see the information on the folded part when spread out.

To overcome these problems, sheets can be saddle-stitched, but for saddle-stitching, it is necessary to always consider the position of the document to be copied on the sheet.

[Purpose of the invention]

In view of these points, the present invention provides a copying method for bookbinding in which, when a manuscript is copied onto paper and saddle-stitched, one of the facing pages of the paper is left blank so that information can be added later. The purpose is to capture and offer.

In this way, once a predetermined number of single-sided copied sheets P are stored in the intermediate tray 39, from now on, the intermediate tray 39
The paper P in 9 is sent out one by one and supplied to the developing section 26 again to copy an image on the back side of the paper P. At this time, since the switching claw member 38 has been switched to the J state shown in FIG.

Incidentally, when copying is to be performed on only one side of the paper, it is sufficient to set the switching claw member 38 in the state shown in FIG. 1 from the beginning.

The paper folding unit 45 is for making a crease in advance in the center of the paper P to be saddle-stitched,
This paper folding section 45 is installed inside the casing 44 of a bookbinding device 46 that can be attached to and detached from the casing 2, and as shown in detail in FIG.
A pair of conveyance rollers 47 and 48 are provided at the entrance. Furthermore, an incomplete circumferential roller 49 located downstream of both rollers 47 and 48 can be joined to one of the conveying rollers 47. A passage 50 is formed on the downstream side of these rollers 47 and 48, and the base end of this passage 50 is inclined forwardly upward toward the joint of the roller 47 and the intermittent roller 49, so that the paper P can be It is designed to be bitten into the joint of 47 and 49. Furthermore, a pair of sponge rollers 51.51 are disposed at the tip of the passage 50, and a passage 52 is further formed on the tip side of the rollers 51.51. Further, a sensor 53 for detecting the presence or absence of paper P is disposed on the side of the passage 52.
3 detects and covers the paper P, the incomplete circumferential roller 49 rotates once in the direction of the arrow. A stopper 54 is provided in the passage 52 on the downstream side of the sensor 53, and is rotatable about a shaft 54a to take a retracted position.
A pair of transport ports 55, 55 are provided at the tip of the passage 52. A plurality of stoppers 54 may be installed according to the size of the paper P, or they may be moved according to the size of the paper P being used.

The sponge rollers 51.51 serve to press down the paper so that only the central portion of the paper P bends in the direction of the joint between the rollers 47 and 49 when the leading edge of the paper L is in contact with the stopper 54. The conveying force is weak, and the circumferential speed of the sponge roller 51.51 is
It is desirable that the circumferential speed be a little faster than the circumferential speed of 7.48. Further, a plurality of pairs of sponge rollers 51, 51 may be provided depending on the size of the paper P.

A non-binding tray 56 is disposed in the casing 44 on the downstream side of the conveyance rollers 55, 55, and is rotatable about a shaft 56a between a solid line position and a chain line position in FIG. Non-binding 1 to lay 56 are unfolded sheets P that do not need to be bound from the paper folding section 45 at the chain line position.
M for being bound from the paper folding section 45
When P is transported, it rises to the solid line position and retreats.

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

This paper binding unit 57 (a binding device 58 such as a stapler that is arranged to be movable up and down and binds the sheets of paper P with a stopper such as a stable, and a receiving seat 59 arranged below this binding device 58, etc. The receiving surfaces 60 at the upper ends of the five receiving seats are arranged 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. It is formed into a sharp edge shape.Also,
A pair of flat guide plates 63 and 64 are provided on both sides of the seat 59, respectively, and are rotatably supported by support shafts 61 and 62 in the vicinity of the U surface 60 of the seat 59. The guide plates 63 and 64 are 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 direction. This configuration allows the base of the wall plate 66 and the guide plate 64 to be
1, which is achieved by forming a comb-like shape that meshes with the
Note that this wall plate 66 can take a retracted position as indicated by the chain line in FIG. Furthermore, the wall plate 6
On the outside of the guide plate 64, there is a width adjustment ZJI which rolls in pressure contact with the paper P on the guide plate 64 and brings the two adjacent sides of the paper P into contact with both wall plates 65 and 66. 67 is provided protrudingly. The axis of this width offset roller 67 is arranged to intersect with the axis of the support @ 62, and this width offset roller 67 can move toward and away from the paper P on the guide plate 64. .

A tray 68 is disposed below the guide plate 64, as shown in detail in FIG.
, θ2. And this angle θ
, by setting θ2 to an appropriate angle, the edge-lined paper P1 that has slipped off the guide plate 64 is placed in the tray 68.
The saddle-stitched sheets P2 are aligned along the other side 70 of the tray 68.

Saddle-stitch binding of sheets P by the bookbinding device 46 comprising the sheet folding section 45 and sheet binding section 57 described above will be described.

The paper P conveyed from the fixing section 34 to the paper binding section 57
The tip of the conveyor roller 47, 48 and sponge roller 51
．． 51, and comes into contact with a stopper 54, which is arranged in advance to match the size of the paper P, and stops. After that, the sponge rollers 51 and 51 continue to rotate, but their conveying force is weak, so there is no risk that the paper P will buckle.

Then, as the paper P is subsequently transported by the transport rollers 47 and 48, the paper P begins to warp near the end of the path 50.

At this time, the incomplete circumferential roller 49 rotates once at the right timing based on the signal from the sensor 53 that detects the paper P, and the bent paper P is caught between the conveyance roller 47 and the roller 49, and is transferred to the center of the paper P. Form a crease. Thereafter, the notch part of the notch roller 49 faces the conveyance roller 47, but before reaching this state, the stopper 54 retreats from the passage 52, so the notch part of the notch roller 49 faces the conveyance roller 547. When the conveying force disappears, the paper P with a crease formed in the center by the conveying force of the sponge rollers 51, 51 is supplied to the paper binding section 57 from the direction of the conveying rollers 55, 55.

When the 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 Figure M3. They 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 width adjusting rollers 67 to both wall plates 63 and 64.
5.66. In this way, all the sheets P constituting one booklet are placed on both guide plates 63.
．． 64, the wall plate 66 is moved in the direction of the support shaft 62 so that the fold of the paper P is received by the seat 5.
Move the paper P so that it is located on the edge 9. And both guide plates 63. , 64 to the position indicated by the chain line in FIG. Then, the sheets P are bound along the folds of the sheets P.Finally, one of the guide plates 63 is rotated to the solid line position, and the wall plate 66 is retracted, so that the saddle-stitched sheets P are bound to the guide plate 64. It slides down along , and is accumulated inside 1 to 8.

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 advance the position of the original ID 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 copied onto five sheets of paper P and saddle-stitched, and pages 1, 2, 19, and 20 of the manuscript are 1 The document δ is to be copied onto one sheet of paper P, and each member of the document sheet to be copied onto the other four sheets of paper P is also in a similar relationship.

In addition, saddle stitch binding is classified into vertical writing and horizontal writing, with vertical writing being stone line binding, and horizontal writing being left binding.

Furthermore, it can be classified by the presence or absence of a cover, and whether it is a full-size copy or a variable-size copy.

Next, the combination of original paper and paper P in the case of carrying out saddle-stitch binding by full-size copying is as shown below.

■) When the paper size is twice the original size Table 1 Here, vertical feeding refers to the case where the short side of the original paper or paper P is perpendicular to the conveyance direction, and horizontal feeding refers to the case where the original paper or paper P is placed at right angles to the transport direction. This refers to the case where the long side of the paper P is perpendicular to the conveyance direction.

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

■) Table 2 if the paper size is the same as the original size This combination is shown 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 problem occurs even if the document is double-sided.

This is illustrated as shown in FIG.

Document D A'3'J for saddle stitching as described above:
Table 4 summarizes the conveyance direction of paper P and paper P.

Table 4 shows that in general, when the number of single-sided originals is n, the total number of original pages is n pages.When the number of double-sided originals is n, the total number of original pages is 2 pages, but in saddle stitch binding In this case, depending on the combination of paper sheets P for one original, it will not work like this.

In other words, in saddle stitching, the size of paper Pa′) whose long side is folded in half, that is, half the size of paper P, corresponds to one page of ff1P, and this paper 1
The manuscript information copied for each page corresponds to one page of the manuscript.

For example, as an example of full-size copying, △3 single-sided original with vertical feed
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-stitch binding is performed, the original size that is copied to half the size of the paper P corresponds to one page of the original.

Saddle binding L for n sheets of manuscript paper; When binding, manuscript paper and paper P
The total number of pages of the original document is summarized as follows based on the above-mentioned magnification ratio table depending on the combination of .

i) For n sheets of single-sided originals Table 5 ii) For n sheets of double-sided originals Next, when performing saddle stitch binding, determine the required number of sheets of paper P and which page is the innermost sheet of paper P for saddle stitch binding. This is extremely important, but in order to calculate the required number of sheets of paper P, the total number of pages of the manuscript paper must be the same, and the number of sheets of the manuscript paper must be the same. There are two possible methods for this: (i) the operator inputs the number of originals, and (ii) the number of originals is automatically input.

Among these methods, 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. Then, assuming that the total number of pages of this manuscript is N, the required number of sheets P of paper 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.
Now that it has been determined, the next question is which paper P should the rotation of the document tray be copied onto.

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

i) In the case of a horizontally written original, as shown in Figure 10, 21-1 is placed on one side of one sheet of paper i.
As well as copying pages, copy page 21 on the back side, and copy page 41-2r (-1) on the other side of paper i. You have to bend.

ii) In the case of a vertically written original, as shown in Figure 11, 4t-2 on one side of one sheet of paper i.
At the same time as copying page r+2, 4l-2i+1
You must also copy page 21-1 on the other side of paper i, and copy page 21 on the back side.

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

Now you can match the manuscript and paper P when doing saddle stitching!・Now that we have determined the required number of sheets of paper ``)'' and the page layout on paper P, we will next consider the movement of the manuscript and paper P in the case of saddle stitching.

As described above, the recirculation type document handling device 4 completes the copying of both sides of the document supplied from the document tray 6 and transfers it to the IC.
Since it has the function of being able to move on to copying the next document sheet later, the document sheet can be processed in a short time during saddle stitching, and the pages of the document sheet 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, we will use
I'm thinking of a place to copy 10 old double-sided manuscripts onto both sides of 5 A3 sheets and saddle stitch them.

To simplify the explanation from now on, 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.1 car load 3: 5 pages on the front. Pages, 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, 14 pages on the back Original 8: 15 pages on the front and 16 pages on the back Original 9: 11 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. 13: Sheet 1: Pages 1, 2, 19, and 20 of the manuscript.
Pages 3, 4, 17, and 18 of the manuscript Paper 3: Pages 5, 6, 15, and 16 of the manuscript Paper 4: Pages 7, 8, and 1 of the manuscript
Pages 3 and 14 Paper 5: Manuscript pages 9, 10, 11, and 1
Four pages of each manuscript are copied, such as two pages.

According to the recirculation type document handling device 4, the number of pages of the document is 1 page → 2 pages - → 3 pages → 4 ((...17
Page → 18th page → 19th page → 20th page, ma1= is 2nd page → 1st page →
4 pages → 3 pages...18 pages → 17 pages → 20 pages → 19
Page order, i.e. manuscript 1 → manuscript 2...manuscript 9
→You can copy the original in the order of 10 or 20 pages→
Page 19 → Page 18 → Page 17... Page 4 -> Page 3 → 2
Page → 1 page, or 19 pages → 20 pages → 17 pages → 18 pages・
...Page 3 → Page 4 -) Page 1 → Page 2, in other words,
It is also possible to copy in the order of original 10 → original 9 . . . original 2 → original 1.

Using such a recirculating type document handling device 4, we will explain the general movements of document stacking and paper P when 10 sheets of A4 horizontally written double-sided documents are copied onto both sides of 5 sheets of A3 paper and saddle stitched. .

First, regarding the document tray, ten document sheets are sequentially placed 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 original in this original tray 6 is conveyed from the lower side, that is, the original 10, onto the contact glass 3, and the 19th of this original @10
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, 15@ of manuscript 8
and pages 16, pages 13 and 14 of manuscript 7, pages 11 and 12 of manuscript 6, 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, 1 of manuscript 1
Copy pages 1 and 2 in this order, and place each page in the document tray 6 with the door J.

In this way, the final state of the originals in the original tray 6 after all the originals 1] have been copied is as follows:
Initial manuscript retrieval status 11j] The pages are in order.

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 2G and is copied at page 19. The paper 1 advances in the directions of arrows C and D, is reversed, and then moves to the direction of arrow F.

F, G, and B are conveyed in this order, and page 20 is copied on the back side of page 19. Thereafter, the paper 1 is transported in the direction of arrow H2E 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,
1.4 pages, 11th page and 12th page are copied on paper 5, and each paper sheet P is stored in the intermediate layer 39.

The order of the sheets P in this intermediate tray 39 is - from top to bottom of the cloth: sheet 5, sheet 4, sheet 3, sheet 2, sheet 1. Therefore, the top paper 5 is re-supplied from the intermediate tray 39 first. Then, this paper 5 is supplied to the developing section 26, and when page 9 is copied, this paper 5 advances in the direction of arrows C and D, and page 10 is copied. This means that the copying of pages 9, 10, 11fA, and 12 of the paper 5 has been completed, 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,
Page 6, pages 3 and 4 on paper 2, and pages 1 and 2 on paper 1 are copied, and the copies are sequentially conveyed to the paper folding section 45.

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

As mentioned above, if the recirculating manuscript handling device 4 is used,
Saddle stitching has the following advantages.

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 conventional recirculating document handling devices that cannot continuously copy both sides of a single document sheet, the number of times the document sheet is circulated is reduced, and the number of scratches and scratches on the document sheet is reduced.
The probability of problems such as problems occurring is low.

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

In the above-mentioned embodiment, the order of copying the manuscript is 19 pages, 20 pages, 17 pages, 18@...3 pages, 4 pages.
If we explain this as pages 1, 1, and 2, but if we invert each manuscript before copying, the order of copying will be pages 20-119, 18, 17, etc. ...4 pages,
It can also be 3 pages, 2 pages, or 1 page.Also, the original WA1 of the recirculating document handling device 4 ~ the first document cellar 1- to Reiro can be placed downward with the front side, that is, the odd numbered pages, facing dry. If the original 10 is positioned above the original 1, 1 page,
Page 2, page 3, page 4...Page 17, 18@, page 19, page 20 or page 2, page 1, page 4, page 3...
The order of pages 18, 17, 20, and 19, that is, manuscript 1
, original 2 . . . , it is also possible to copy original 9 and original 10 in this order.

Above, we have explained the case where 10 A4 double-sided originals are saddle-stitched onto 5 sheets of Δ3 paper using the recirculation type original handling device 4, that is, the paper size is twice the original size and the double-sided original platform is C1. First, an example of saddle stitching in another embodiment will be explained.

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

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 at the bottom.

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 @...I! Page I, page 3, page 2, and page 1 are copied in this order, and the original W@1) is returned to the document tray 6 in order. Therefore, the final document set state is the same as the initial document set state, and the page order is the same.

To summarize the movement of paper P at this time, tf
Ru.

1) Paper power [Paper 1 is fed from the tray 29 -> Reversal Copy 20 pages and copy 919 pages -> Intermediate tray 39 2) Paper power [Feed the paper 2 from the tray 29 ~ → A 39 3 ) Feeding paper 3 from paper cullet 29 -> Reversal Copying page 16 - Copying pages 1-15 - → Intermediate tray 39 4) Feeding paper 4 from paper cassette 29 -> Copying page 14 -> 13 Copy page → Intermediate tray 39 Copy page 12 → Copy page 11 → Intermediate tray 39 Copy page 10 → Copy page 9 → Paper tray 5 7) Feed paper 4 from paper cullet 39 → Reverse copy page 8 → Copy page 7 → Paper tray 5 8) Feed paper 3 from paper cassette 39 → Reverse copy page 6 → Copy page 5 → Paper 1 to Ray 5 9) Feed paper 2 from paper cassette 39 → Reverse Copy page 4 → Copy page 3 → Paper tray 5 10) Feed paper 1 from paper cassette 39 → Reverse copy page 2 → Copy page 1 → Paper tray 5 Also, copy the side where information is written. Even if you place the manuscript on the manuscript tray 6 so that it is facing down and page 20 is on top, and page 1 is under the cloth, the order in which it will be copied will be page 1, page 2, page 3, and page 4.
Pages: 17 pages, 18 pages, 19 pages, 20 pages, and saddle stitch binding is possible 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 noise per document and the document is a double-sided document, let us 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 Original 2: 5 pages, 6 pages, 7 pages, 8 pages Original 329 pages, 10 pages, 11 pages, 12 pages Original 4: 13 pages, 14 pages , 15 pages, 16 pages manuscript 5; 17 pages, 18 pages, 1
Pages 9 and 20, and as shown in Figure 15, the front side, that is, pages 1 and 2, pages 5 and 6, pages 9 and 10, pages 13 and 1
The originals 5, 4, 3, 2, and 1 are placed on the original tray 6 in the order from the bottom, with pages 4, 17, and 18 facing upward.

In other words, the document 5 at the bottom of the document tray 6 is fed onto the contact glass 3, and the documents 5, 4, 3 are fed onto the contact glass 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 page, 2 pages, etc. are possible.

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 and covered. 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. This is manuscript 5
Since all the copies have been completed, the original fR5 is turned over again and placed on top of the original 1 in the original tray 6. Next, place original 4, original 3, original 2, and original 1 on the contact glass 3 in this order.
The document is supplied to the top and copied in the same manner as described above t1, and when the copying is completed, it is re-polished and reversed, and then returned to the document tray A6.

When the copying of the five original sheets has been completed, the original set on the original 1 is the same as the initial state shown in FIG. 15, and the pages are aligned. Note that there are two pages of information on one side of one manuscript sheet, and the electrostatic latent image of the unnecessary page is erased from the photoreceptor drum 28 by an erase means on the platform for performing the above-described copying method for individually copying this information. Remove.

To explain the movement of the paper at this time, when paper 1 is supplied from paper h set 29 and page 20 is copied, paper 1 is reversed and 19@ is copied on the back of page 20. Thereafter, this paper 1 is stored in the intermediate tray 39. Similarly, from the paper cassette 29, paper 2, 'paper 3, and paper 4 are
, paper 5 is supplied, and paper 2 contains pages 18 and 17,
Pages 16 and 15 are copied on paper 3, pages 14 and 13 on paper 4, and pages 12 and 11 on paper 5, respectively, and stored in 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, pages 8 and 7 are on paper 4, and pages 6 and 7 are on paper 3.
Pages 4 and 3 are copied to paper 2, and pages 2 and 1 are copied to paper 1, respectively.
5. Both guide plates 6 of the paper binding section 57 after the fold is formed in the paper folding section 45.
FIG. 17 shows the stacked state of one sheet on 3.64. As is clear from this figure, each paper [) has an A3t
The copied pages 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, the document tray 6 is placed so that pages 1 and 2 are on top with the side with information facing upwards, and pages 19 and 20 are placed under the cloth. 10 within
Place a sheet of original paper.

The document feeder is fed from the bottom, so pages 20, 19, and 1
8 pages, 17 pages...4 pages, 3 pages, υL1 page, or 19 pages, 20 pages, 17 pages, 18 pages...3
The copies are made in the order of page, page 4, page 1, and page 2, and the originals are returned to the original set 6 in order. The final document tray state is the same as the initial document tray, 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 → Copy page 20 - = - Copy page 19 -> Intermediate tray 39 Copy page 18 -> Copy page 17 - -> Intermediate tray 39 3) Paper 3 from paper cullet 29 4) Feed paper 4 from the paper cassette 29 → reverse Copy circulating page 14 -) - Copy page 13 - -> Intermediate tray 39 12 Copy page → Copy page 11 → Intermediate tray 39 6) Feed paper 5 from intermediate tray 39 → Copy page 10 →
Copying page 9 -> Paper folding section 5 Copying page 97 Copying -> Paper folding section 5 Copying page 95 Copying - 10th paper folding section 5 9) Feed paper 2 from intermediate tray 39 -> 44 reversal Circulation Copy page 93 Copy page → Paper folding section 5 10) Feed paper 1 from intermediate tray 39 -> 2 Reversal ・
Copying circulating pages - Copying 1 page → Paper folding section 5 The above describes the movements of the original mD and paper P in all the combinations of original paper and paper P when performing saddle stitching with full-size copying, that is, page editing. This will explain how to do this. It should be noted that the same applies to the case of variable size copying, so the explanation will be omitted. In addition,
The variable magnification ratio during variable-magnification copying is determined by the document size, paper size, and document placement direction.

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

Saddle stitch binding when the original size and paper size are the same as described above is performed when the original information is separated in the center and it is not necessary to view the left and right original information at the same time. 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, if a large table or graph is drawn across the left and right pages of the manuscript, this table,
It is not recommended to separate and copy graphs, etc. Therefore, in such a case, unlike saddle stitching where the left and right manuscript information can be separated, for example, paper 1
], do not duplicate on page 1, and copy 1 of the manuscript on page 2 of paper P.
v (and also copies two pages of one manuscript on page 3 of paper P, but the first odd-numbered pages of paper P are not copied, and the next even-numbered page is copied from manuscript 1). If you copy one page, you can see the information on the left and right sides of the manuscript at the same time when you look at the saddle-stitched paper [2].

In this case, duplication η'' is not performed on the first odd-numbered pages of paper P, and one page of the manuscript is copied from the next even-numbered page, so
If the number of odd pages that are not copied is n, then the true number of original manuscripts is written as N + n.

Therefore, the required sheet II of sheets ``)'' becomes an integer 1 that satisfies the equation 2 (1) above.

Then, when copying is performed on page 1 of paper P, the page layout of paper t) is as shown in FIG. 19.

Next, if the information on the left and right sides of the manuscript is divided, saddle stitching can be performed so that either the left or right page is left blank during viewing. This blank page can be used for notes or to add information later, and it can also be made easier to use by writing down lines, squares, etc. In this case, the first page and the last page of paper P are not copied.

The number l of sheets P required for such one-side 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-stitch binding modes described above, a cover paper is set in any one of the three paper pressurizers 1 to 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 furthermore, sheets of different colors and thicknesses or sheets with fixed text may be prepared separately.

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, if the first page of the paper P is placed on top, the binding will be on the left edge, whereas in the case of vertical writing, if the first page of the paper P is placed on the - side, the binding will be on the left edge. The binding will be on the right edge.

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) Turn the first original document platen 1~ horizontally upside down and make the transfer position to the paper P the same as in the case of a horizontal 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 stitching method in case (i) described above is as shown in FIG. In other words, the layout of the first page of paper P is 41-2 i + 4l-2 on the back of page 2 on the - side.
Page i+1 is copied, and the other side is 21 on the back of page 21-1.
The page will be copied.

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

In addition, in the case of (11) mentioned above, for the original set of horizontally written originals shown in Fig. 20a, as shown in Fig. 20S, saddle stitching of the vertically written originals is done by turning the originals upside down. It becomes possible. At this time, the page layout of the paper P is the same as in the case of a horizontally written original.

Next, I will explain the binding margin during saddle stitching.
In saddle-stitch binding, if the sizes of the original paper sheets P are the same, the information on the right half of the original paper must be copied separately in one page, so there is a possibility that information in the center of the original paper may be missing.

In order to eliminate this inconvenience, the information near the center of the document can be copied so that it is 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 the above-mentioned capacity is not enough, 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, making it difficult to save the manuscript. Cheap.

Therefore, I only edited the saddle stitching of the paper ``) according to the page layout mentioned above, and the paper P was edited without center folding or saddle stitching.
By discharging the paper P, if the discharged paper P is used as a new document tray, both the left and right pages of this new document tray can be simultaneously copied, 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, and the original from the original tray is subjected to fM light on both sides as necessary, and then transferred to the original tray. A recirculation type document handling device designed to return documents;
and a copying device that is equipped with an intermediate tray for temporarily storing paper that has been copied on one side in preparation for copying on the back side; a copying device that is connected to the conveyance path of this copying device and forms a crease in the center of the paper. The bookbinding device has a paper folding section for folding the paper and a paper binding section connected to the paper folding section, so it can easily handle vertically written documents without making complicated movements of the documents and paper. This provides an excellent effect in that saddle stitching of horizontally written originals can be performed. Note that it is of course possible to perform edge binding or non-binding.

〔Effect of the invention〕

As explained above, the copying method for bookbinding according to the present invention includes:
From the back side of half of the first sheet of paper to the front side of the next sheet,
The pages are ordered from the back side, the back sides of both halves of the last sheet are placed in consecutive page order, and the first page is placed from the back side of the other half of the last sheet.
The pages are arranged in order from the back and front of the next sheet toward the second sheet, and the original is copied only to one of the two pages of the two-page spread sheet. It is possible to edit saddle-stitched pages such that one of the backs of the second page is left blank.
