Abstract

PURPOSE:To automatically execute the supply and copying work of originals by copying a series of continuous originals on both surfaces of one copying paper, and providing a page continuous copying control means to discharge from the first to fourth originals. CONSTITUTION:When a series of copying processing is completed, while the first original conveying belt 10a is stopped, the second original conveying belt 10b and a feeding roller 15 are driven, the fourth page original D4 is discharged to a temporary storing part 16 and overlapped on the third original D3. Thereafter, the first original conveying belt 10a is driven, the first page original is sent in the downstream direction and an original mounting plate 18 is rocked upwards. In such a way, in the sequence from the lower part, originals D1-D4 from the first page to the fourth page are mounted, after the original of a set of four sheets is all discharged to the temporary storing part 16, a lever 21 is rocked in the lower direction and four originals D1-D4 are discharged to an original discharging tray 23. Thus, at the time of the page continuous copying, the operator is completely released from the manual operation.

Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is a page continuous copying system that organically combines a so-called double-sided copying function and a double-sided printing function to automatically perform so-called page continuous copying. This relates to copying machines.

"Prior Art" Conventionally, for example, as shown in FIG. 1, the first page of the original is copied on the right side P1 of the back side of copy paper C, the second page of the original is copied on the left side P2 of the front side, and the second page of the original is copied on the right side P3 of the front side. By copying the third original, and then copying the fourth original on the left side of the back P, a double-sided copy is made in the form of double-sided binding, and the paper is folded along the center line of copy paper C and bound. The method of copying in such cases is called continuous page copying.

"Problems with the Prior Art" When performing continuous page copying like this, double-sided copying and double-sided printing are performed as described above, but even if you simply perform double-sided copying and double-sided binding printing, , as shown in Figure 1, the page number of copy paper C when folded does not match the page number of the original. Therefore, in a highly automated copying machine that uses an automatic document feeder, it is difficult to feed the original. It is necessary to skillfully combine order articulation and double-sided copying functions, and a new mechanism for this purpose is required.

For example, an example of a conventional document feeder is
The document feeder described in Publication No. 2942 has succeeded in performing double-stitch printing using two document conveyance belts, but this technology alone can only print on one side of the copy paper in the order of page numbers of the document. Copy paper that has already been copied by a copying machine having the document feeder described in the above-mentioned Japanese Patent Application Laid-open No. 60-2942, in which only the corresponding image is copied, and it is not possible to perform so-called continuous page copying on both sides. If you turn the paper upside down and repeat the copying process, a double-sided copy with double-sided binding will be made, but the page numbers on the copy paper obtained in this way do not match the page numbers on the original, so you can simply fold it as is. It cannot be bound.

In addition, an example of a copier with a double-sided copy function is
For example, a double-sided copying machine disclosed in Japanese Unexamined Patent Publication No. 107657/1984 is known. When attempting to perform continuous page copying as shown in FIG. 1 using this double-sided copying machine, the operator first needs to contact For example, first place the third page of the original on the left side of the glass, then place the second page of the original on the right side to copy onto one side of the copy paper.
After removing the page and the third page of the original, the fourth page of the original must be placed on the left side of the contact glass, and the first page of the original must be placed on the right side to copy the other side. Currently, there is no automatic document feeder that can change the order of documents placed on a contact glass in a complex manner, even if the
Even if you use the double-sided copying machine described in Publication No. 07657,
In order to perform continuous page copying, it was necessary to rely on an operator to supply the original document14.

In addition, when performing page continuous copying, for example, the first and fourth pages of the original are simultaneously copied, and the second and third pages of the original are simultaneously copied side by side, so if the automatic document feeder continues to eject the originals, the originals will not be ejected. The order of the pages of the original manuscript is messed up, and the operator is required to rearrange the pages.

``Object of the Invention'' Therefore, the object of the present invention is to be able to completely automatically supply and copy originals without relying on an operator, and to automatically sort the ejected originals in the order of page numbers. It is an object of the present invention to provide a page continuous copying machine that can arrange pages side by side.

"Structure of the Invention" In order to achieve the above object, the main means adopted by the present invention is that an automatic document feeds each document M placed on a document tray to a copying position on a document table. In a copying machine that includes a feeding device, a copying machine main body having a duplex copying mechanism, and a control device that controls the automatic document feeding device in association with the copying machine main body, the automatic document feeding device sequentially prints images starting from the document tray. 4 pieces sent out 1

After driving the document conveyance means to convey the second and third documents to the copying position and having the copier main body perform the copying operation on one side of the copy paper, the second and third documents are transferred to the copying position. ejects the original to the original storage section, then conveys the fourth original to a predetermined copying position, and conveys the evacuated original to a predetermined copying position to perform the copying operation on the other side of the copy paper. After the copying machine main unit has done this, the fourth original is ejected next to the third original, and the first original is ejected next to the second original to form one copy sheet. This page continuous copying machine comprises a page continuous copying control means for copying a series of continuous originals on both sides of the page and ejecting the first to fourth originals.

Among the above components, the document temporary evacuation means may be provided between the first and second document conveyance means, or upstream of these document conveyance means in the document conveyance direction. Further, the first and second document conveying means may be a pair of original fgllR conveying belts arranged side by side as in the embodiment described later, or alternatively, a roller for conveying the document. Further, the document temporary storage means can be constructed of a document placement plate, a feed roller, a driven roller, etc. shown in the embodiment described later, but it is not necessarily limited to this, and may be replaced with various rollers, suction means, etc. It is possible.

Also, is the page continuous copying control means based on a combination of individual circuits? - Although it may be possible to perform the control by controlling the number of units, it can also be achieved by program control using a microcomputer as in the embodiment described later.

Members such as the roller above the feed roller 15 (ill roller, fulcrum 20, lever 21, and driven roller 22) are attached to the housing 7, and move up and down as the housing 7 is opened and closed.

On the other hand, as the copying machine main body 2 having a double-sided copying mechanism on which the automatic document feeder 3 is placed, various types can be used.
The double-sided copying machine described in Japanese Patent No. 7657 is one example. FIG. 6 shows a schematic structure of such a double-sided copying machine. In this case, the copy paper taken out from the cassette Z4 by the paper feed roller z5 is fed to the timing roller 26 and temporarily stopped there.

On the other hand, the image of the document placed on the document table 1 is scanned by an optical system 28 that moves along the document table 1, and is scanned by a moving mirror 29. The light is irradiated onto the surface of the photoreceptor 32 through the lens 309 and the reflection mirror 31, forming an electrostatic latent image on the surface of the photoreceptor 32. The electrostatic ill image thus obtained is applied with toner by the developing device 33 and visualized.

As the photoreceptor 32 to which the visualized toner image is attached rotates, the toner image is deposited on the surface of the copy paper that is sent out by the driving of the timing roller 26 and supplied to the transfer section 34 via the feed roller 27. After the image is transferred, the copy paper is fed to a fixing roller 36 via a conveyor belt 35.

The copy paper with the toner image formed on one side is further supplied from the fixing roller 36 to the feed roller 37, and then guided by a switchable switching guide 38 provided on the downstream side of the feed roller 37 to a lower temporary position. sent to the discharge roller 39,
It is discharged to a temporary discharge tray 40.

In this way, the copy paper discharged onto the temporary discharge tray 40 with its back side facing down, which has not yet been subjected to the copying process, is transferred to the feed roller 41 which rolls into contact with the temporary discharge roller 39.
It is sent out in the direction of the feed belt 42 by. A large number of proteges 43 are pressed against the feed belt 42, and these nip rollers 43, 43, 43...
The copy paper is gripped by the feed belt 42 and sent in the direction of the timing roller 26, reversed along the bending guide 44 provided near the timing roller 26, and inserted again into the nifter point of the timing roller 26. It will be done. Due to this 180° reversal by the bending guide 44, the copy sheet is inserted into the timing roller 26 with the back side, which has not yet been subjected to the copying process, facing upward.

In this state, when the original placed on the original platen 1 is replaced and the optical system 2 is moved again and the photoreceptor 32 is started to rotate,
When an i-document image for a new document is formed on the photoreceptor 32 and the timing roller 26 is driven to rotate at an appropriate timing, the new document image is transferred to the back side of the copy paper that has not yet been subjected to copying processing. . Vt, the copy paper is sent forward via a conveyor belt 35, fixed by a fixing roller 36, and then sent to a feed roller 37. At this point, the switching guide 38 is switched, and the copy paper discharged from the feed roller 37 is not temporarily sent in the direction of the clearing roller 39, but reaches the paper discharge roller 46 via the guide plate 45, and from there. The paper is discharged to the paper discharge tray 47.

For example, the copying machine main body 2 may be configured as described above, but the copying machine main body that can be used in the present invention is not limited to the one described above, and may be replaced with a copying machine having various other duplex copying mechanisms. can.

For example, JP-A-60-43670 and JP-A-60-4
Publication No. 1058 is one example.

Next, with reference to the flowchart shown in FIG. 3 and each figure in FIG. 2, a processing procedure when controlling the above-described embodiment apparatus using a micro convenience store will be explained.

In addition, Sl in the following explanation.

S2... indicates the number of the processing hand 11fl (step).

As shown in FIG. 3, first, in step S1, the duplex copy mode is selected as the processing mode of the copying machine main body 2, and the continuous page copy mode is selected as the control mode of the automatic document feeder 3.

These are selected by the operator pressing a key on the operation panel.

Next, the operator sets the original on the original tray 4 (3
2) In this case, the original is placed on the original tray 4 by turning over the east side of the original and placing the first page of the original at the bottom.

Next, the operator presses the start switch on the operation panel (S3), and the micro combinator determines whether or not the document is placed on the document tray 4 (S4). A mechanical unit (not shown) provided on the original tray 4.

Alternatively, if it is determined that there is a document detected by searching the output status of an optical document detection sensor, S5
Activate a solenoid (not shown) in the step shown in Fig. 2 (
As shown in bl, the document guide 12 is swung around the fulcrum 11 so that its leading end is in close contact with the document table 1, and the document feed start roller 5, double feed prevention roller 8. Feeding roller 6
,9. The first document conveyor belt 101 is rotated to prevent double feeding of documents, and the first document, that is, the lowest document D1 (first page) is moved toward the document table 1.

[As described above, the tip of the document guide 12 is in close contact with the stacking platform 1, so the document D1 that has reached that position is guided by the document guide 12, and its traveling direction is twisted upward; At this point, the rotation of the evacuation roller 14 has started, and the document sent into the evacuation duct 13 is sent further into the back by the evacuation roller 14. Then, by stopping the evacuation roller 14 at an appropriate time, the document is nipped by the evacuation roller 14 with its end separated from the document guide 12 and present in the evacuation duct 23 as shown in FIG. At the same time as the evacuation roller 14 stops, the document guide 12 is driven and stops at the raised position as shown in FIG. 2 (al).

Next, in S6, the microcomputer determines whether or not there is a document on the document tray 4, as in 84, and if it is determined that there is a document, the microcomputer moves the feed start roller 51, double feed prevention roller 8. Feed roller 6.9. First and second document transport belts 10. and 10b to convey the lowest document D2 (second page) to a predetermined copying position directly below the second document conveyance belt lOI, as shown in FIG. and the second document transport belt 10
Then, the second page document D2 is fixed at that position.

Further, the document feeding start roller 5 stops when feeding of the second page of the document is completed, and suspends feeding of the third page of the document for a while (37).

In this way, when the second page of the original D2 is placed in the copying position on the left half of the original table 1, the microcomputer subsequently determines in S8 whether or not there is another original on the original tray 4.

If it is determined that there is a document, in S9, the lowest document D) (3rd page) is moved to the first document conveyor belt 101 by driving the first document conveyor belt 101 or the like.
The document D3 is conveyed to a predetermined copying position directly below m, and the first document conveying belt 101 is stopped at this position, and the third page document D3 is fixed at a predetermined copying position on the right side of the document table 1.

Note that in this step S9, the second document conveyance belt 10I is stopped. Therefore, here Figure 2 (
As shown in dl, the second page of the original D2 and the third page of the original D3 are placed at predetermined positions on the original platen l in a state in which page continuous copying is possible.

Next, as shown in SIO, the copying machine main body 2 is operated to start moving the optical system 28 and the like, and the photoreceptor 32 is driven to rotate. Furthermore, by rotating the timing roller 26 or the like at a certain timing, the copy paper taken out from the cassette 24 is transferred to the transfer section 3 near the photoreceptor 32.
Send it to 4.

As described above, the copy paper that has been transferred from the photoreceptor 32 is transferred to the conveyor belt 35. Fixing roller 36° Feed roller 3
7. Switching guide 38. It is discharged to a temporary discharge tray 42 through a temporary discharge roller 39, and then to a feed-out roller 41.
．． Feed belt 42. It passes through the bending guide 44 and is inserted into the nip point of the timing roller 26.

When the preparation for copying on the back side is completed in this way, the microcomputer moves the first and second document transport belts 10. and 10b, the feed roller drives 15 to feed the original II&D*, Dt of the second and third pages.
is discharged to the temporary storage section 16. At this time, temporary storage section 1
The document placement plate 18 in D2.6 is at the lower position as shown in FIG. D is on the rear end side or on the document placement plate 18, and the leading end side is the feed roller 1.
9, it is placed in the temporary storage section 16.

This state is shown in FIG. 2 te+.

Next, the microcomputer again determines whether there is a document on the document tray 4 (512) and says, ``If there is a document, the lowest layer document D4 (fourth page) is moved to the document feed start roller 5. Using the roller 6 and the first and second document conveyance belts 10. and 10b, the document is conveyed to the copying position directly below the second document conveyance belt 10.
l) (S L 3. When the conveyance of the fourth page of the original is completed, the original guide 12 is swung downward again in S14 to bring its tip into close contact with the upper surface of the original platen l, and the evacuation roller 14 is rotated. The first page document, which had been reversed and evacuated into the evacuation duct 13, is returned to the top of the document table 1. At this time, by reversing the first original f1% conveyor belt 10° within a predetermined time. , fj The 41st page original D1 is sandwiched between the first original transport belt 101 and the original table l. When the first page original D1 reaches a predetermined copying position, the first original transport starts. Belt 10□
(315), and at this time the document guide 12 is raised (FIG. 2(g)). In this way, when the fourth page document D1 and the first page document D1 are placed on the left and right sides of the document table 1, the main body of the copying machine is driven according to the reverse side copy mode. That is, at this point, the switching guide 38 is switched to the side shown in FIG. 6, and the movement of the optical system 28 and the rotational drive of the photoreceptor 32 are started, similar to the copying operation on the front side. In response to this, the timing roller 26 is driven at a certain timing, and the copy paper that has undergone the copying process on one side is transferred to the transfer section 3.
It is conveyed in the direction of 4, and at the transfer section 34! l!
The original images for the first and fourth pages of the original are transferred onto the copy paper, and the transport belt 35. Fixing roller 36
The aforementioned switching guide 38 on the downstream side of the feed roller 37 is fed to the feed roller 37 through (S16).
Since the copy paper is switched to the illustrated position as described above, the copy paper discharged from the feed roller 37 is sent to the paper discharge roller 46 via the guide plate 45, and is finally discharged to the paper discharge tray 47 (317). ).

In this way, the image of the first page document D1 is copied on the right page on one side of the copy paper discharged to the paper distribution tray 47, and the image of the second page document D1 is copied on the back side page.
The copy image of D2 is transferred, the copy image of the third page document D3 is transferred to the right page, and the image of the fourth page original D3 is transferred to the back side of the page, and As shown in the figure, the copy paper has undergone continuous page copying.

In this way, when a series of copying processes is completed, the process moves to step 11131B to eject the original on the original platen l and to S19.
1B, as shown in FIG. 2 (hl), while the first document conveyance belt 10. is stopped, the second document conveyance belt 101. and the feed roller 15 are driven to read the fourth page of the document. It is discharged to the temporary storage section 16 and stacked on top of the third page document D3.

Thereafter, while the feed roller 15 remains rotated, the first document conveying belt 10. Driving it was fixed underneath! At the same time, a solenoid (not shown) is activated to send out the page of the original in the downstream direction. The mounting plate 8 is swung upward.

As a result, the first page document D1, which has been conveyed on the document table 1, is sent out from the feed roller 15.
The tip comes into contact with the lower surface of the document placement plate 18, is guided by the document placement plate 18, and slips under the documents D2 to D from the second page to the fourth page. When the first page of the original document is discharged from the feed roller 15, the first to fourth pages of the original document ~D4 are placed in order from the bottom as shown in FIG. The tip is now approaching the feed roller 19.

In this way, when all the yy products of a set of four sheets have been discharged to the temporary storage section 16, the lever 21 swings downward by the operation of a solenoid (not shown), and the driven roller 22 at the tip of the lever 21 moves the document to the feed roller 19. When contact is made between the two originals D1 and D, the rotation of the feed roller 19 is started, and the four originals D1=D+ are ejected to the original ejection tray 23 as shown in FIG. 201 (S19). ).

When the ejection of the original is completed in S1.9, it is further determined in S20 whether or not there are any more originals to be copied on the original tray 4. If there are originals, the process returns to S5 and the process described above is performed. Copying of the sixth and subsequent pages is performed in a similar manner.

If it is determined in step S4 that there is no original on the original tray 4, the copying process cannot be performed at all, so the process is stopped.

Further, if it is determined in S6 that there is no original, that is, if there is only one original, the process jumps to S14, and sets the first original, which had been evacuated, at the copying position (315). , 316 and subsequent copying processes are executed.

Furthermore, if it is determined in S8 that there is no original, that is, if there were originally only two originals on the original tray 4, the process jumps to SIO and copies the second original. , and further in S12, S
14, the first original is taken out from the retracted position, and the copying process is executed.

Furthermore, in 34.56.58, even though it was determined that there was a document, if it was determined that there was no document only in S12, there were only three documents on the document tray 4. First, the copying process on the front side of the second and third originals is completed in S10, and after that, it is necessary to copy the first page of the original onto the one-page spread side of the copy paper, that is, the right side of the back side. Therefore, the process jumps to S14, takes out the first original from the retracted position, and performs copy processing on the back side of the copy paper. As a result, only the last page of the copy paper in the state shown in FIG. 1 remains blank.

Without changing these processes, the number of manuscripts from the beginning was reduced to 4.
This means that if the manuscript is not divisible by 4, the number of manuscripts remaining after dividing by 4 will be copied in order from the front page, and all blank pages will be consolidated at the back. This means that when the book is bound, there is no inconvenience such as blank pages appearing in the middle, and extremely satisfactory continuous page copying can be performed.

However, in this case, the documents will be ejected in the order of 2nd page, 3rd page, 4th page, 1st page from the bottom, and the page numbers of the documents will not be aligned, but even in this case, the page numbers will not match. The photo function is fully achieved.

In the above embodiment, when placing the originals on the original tray 4, the originals with the youngest pages are placed face down, so the temporary storage section 16 and the original placing plate 18 are provided at the part where the originals are ejected. I needed it.

Further, by disposing the document temporary evacuation means between the first and second document conveyance belts 10m and 10+, the document is taken out from there. Therefore, in the above example, the first page original ff%D+ is immediately moved to the first document transport bell)1
0. It is an efficient device in that it can be supplied to many people.

In the second embodiment shown in FIG. 4, some modifications have been made in these points, but many parts are similar to the second embodiment
This is similar to the example shown in the figure. Therefore, only the parts that are different from the example shown in FIG. 2 will be described below. In the example shown in FIG. 4, the directions in which the originals are placed on the original tray 4 are different, and the originals are placed ti in order from the top to the one with the largest page number. Therefore, the vertical positions of the double-feed prevention roller 8 and the document feed start roller 5 are reversed from the example shown in FIG. 2. Also, manuscript tray 4
A paper feed roller FR for pushing the upper document toward the document feed start roller 5 is provided so as to be movable toward and away from the document. Further, the document temporary evacuation means is the first document feed belt 10. A document guide 12' is provided further upstream than the document feed guide 12', which cuts the document transport path 48 between the document feed start roller 5, the double feed prevention roller 8, and the feed roller 6.9 into an L-shaped evacuation duct 13'. , the evacuation duct 13', and an evacuation roller 14' provided in the middle of the evacuation duct 13'. The document temporary storage section 16' is provided at the upper part of the second document conveyance belt 10b, and is a bending guide for guiding the document discharged from the second document conveyance belt 10b to the temporary document storage section 16'. 49 is the downstream il of document table 1! The end portion is connected to a feed roller 15' provided upstream of the temporary storage section 16', and the original sent from the second document transport bell zob is turned over and sent to the temporary storage section 16'. configured to eject. Note that the temporary storage section 16' is provided with a document placement plate 18' that can swing around a fulcrum 17, and furthermore, a feed roller 19' and a driven roller that can move toward and away from the feed roller 19' are provided downstream of the document placement plate 18'. 22' is provided. In this embodiment, the document placement plate 18', the feed roller 19', and the driven roller 22 constitute temporary document storage means. In addition, the above feed roller 1
9' and a document output tray 23' that receives the document sent out by the driven roller 22' is connected to the first document conveying belt 10. It is located almost at the top of the

With this device, documents with large page numbers are sent in order from the top, with the first page, second page, etc., so if the document has n pages, the first page is page n, and the second page is page n-. I will send you the first page of the manuscript.

Steps St' to 320' in the flowchart showing the processing procedure of this apparatus shown in FIG. 5 are almost the same as the flowchart shown in FIG. Only these will be explained below.

That is, steps 31' to S4' are the same as the flowchart shown in FIG. 3, but in S5', the first document is fed by bringing the paper feed roller FR)tc into contact with the document,

4', after the document guide 12 is raised, the document sent out from the withdrawal duct 13' by the reversal of the withdrawal roller 14' is inserted into the document conveyance path 48 again.
Eventually, its leading edge is inserted between the document feed start roller 5 and double feed prevention roller 8, but at this time, the document feed start roller 5 is reversed, and the W41st document that has been inserted is This acts to return the top layer of the document placed on the document tray 4. Further, at this point, the paper feed roller FR is separated from the document layer, making it easy to reverse feed the first sheet (nth page) of the document.

In this way, the trailing edge of the first manuscript is the original! 1% conveyance path 4
8, the document guide 12' is switched downward as shown in FIG. As the belt 108 is driven, the first document is transferred to the first document conveying belt 10. as shown in FIG. It will be sent to the copy position directly below.

Subsequent copy processing (S16') and copy ejection (S17')
) is the same as the flowchart shown in gj43. Then, at 818', first the fourth document is printed, then the second and third document D2. Then, the document placement plate 18' is lifted upward and the first document D is ejected onto the second document D2 (FIG. 2 (1)). Figure 2 IJ)) (S l 8'
), ~D, are placed in order in the temporary storage section 16', the driven roller 22' is lowered in S19, and the driven roller 22' and the feed roller 1
6' and the document ejection tray 23 in a bundled state of four sheets.
’ to be discharged. The state after discharge is shown in FIG. 2 (k+).

In each of the above embodiments, whether the copied item is a left-opening copy or a right-opening copy depends on the orientation of the original placed on the original tray 4. When placed, the first embodiment (as shown in FIG. 2) opens to the left, and the second embodiment (as shown in FIG. 4) opens to the right.
