Abstract

PURPOSE:To obtain a small-sized and full-automatic both-surface copying machine by providing a controlling means for the feeding of an original and its stopping at an exposure position, the conveyance of the original after exposure, and the movement of the original and a copying material from a collection part to a feeding means. CONSTITUTION:Originals stored in an original storage part 38 are fed, sheet by sheet, by the feeding measn 39 and moved on an original placing plate 2 by a conveying device 27. Then, the conveying device 27 stops by the detection of a sensor to locate an original at the exposure position. Then, an image is formed on one surface of a copying material 17 fed from a cassette 16. Thus, a specific number of exposed originals are collected at a collection part 38 by a collecting device 28 and when all one-surface exposed copying materials 33 are collected at a storage part 32, a preset command for other-surface copying is sent out. Consequently, a controller releases separators 29 and 36 and allows an original 30 and a copying material 33 to be fed, performing other-surface copying. Thus, the samll-sized and full-automatic device is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double-sided copying apparatus capable of copying on both sides of a copying material.

In particular, it provides a duplex copying device that has the function of automatically copying both sides of a document onto both sides of copying material. While copying occupies a large role, there is a strong demand for resource and labor saving (there is a strong need for a copying machine that can further improve the conventional copying machine and has functions that can meet various demands).

The present invention aims to provide a copying apparatus that satisfactorily meets such demands.

Currently, some copying machines have an automatic document feeder, and some have the function of making double-sided copies of copy materials, but even in the latter double-sided copying machines, after copying one side, the other side is copied again. There is no automation, there is no automatic document feeding, and there is no one that allows one-sided copying at will, so it is insufficient in terms of labor saving, or it has both functions. Even if it were, the device would become complicated and large.

In view of the above points, the present invention provides a copying apparatus which, on the one hand, maintains the function of complete automation, and on the other hand, is capable of manual feeding of originals or copy materials. The present invention is also a copying apparatus that can selectively perform various copying methods.The structure and operation of the present invention will be explained below.

The configuration of the present invention will be explained in detail with reference to FIG. 1.2.

A detailed explanation of the present invention will be given in FIG. 1.2.

The document 3 is stored in the document storage section 38, and the IIA
It moves on the table stand 2 and is placed in the exposure section 1#.

After a certain period of time: It operates to stop the transport/S system 27.

Next, an illumination lamp 6 is attached to the document 3, a movable reflection mirror 4 that moves together with the illumination lamp 6, and a 4-hyperactive reflection mirror 5 that moves in one direction at a speed of 1f, which is 1/2 of the movable reflection mirror 4. While keeping the optical path length equal, the light passes through the lens 7 and the fixed reflection mirror 8.9, passes through the slit, and is imaged onto the photosensitive drum 1.

That is, the original i143 is illuminated with slit light while being scanned by the optical system (illumination unit).

The photosensitive surface of the photosensitive drum is made up of a transparent insulating layer on top of the photosensitive layer.
The positive band straightener 11 supplied with the pressure #ILa allows the voltage to be adjusted exactly. Then, at the same time as it reaches the exposure section 12, it is subjected to AC static elimination by the AC radiator 13 to which AC high voltage current is supplied from the pressure ridge source 10.

Next, an electrostatic FA image is formed on the drum surface (photosensitive surface) by the entire surface exposure by the entire surface exposure rung 14 and enters the imager 15.

The development is performed by powder development using the sleeve method, and the electrostatic latent image is visualized.

Next, copy material 1 is fed from the cassette (cassette) 16 and sent to the top.
7 is brought into close contact with the photosensitive drum l, and the transfer charger 18 applies a high voltage to the photosensitive drum l.
The photosensitive drum l is charged by the positive high voltage source from
The upper image is transferred onto the blank material 17.

After the transfer, the copy material 17 is separated from the photosensitive drum 1 by a separating section 19, guided to a fixing section 201C, coated with an electric layer, and then neutralized by a static eliminator 23.

The copy material is discharged and stored in the copy material storage section 32 by the discharge roller 22.

On the other hand, the drum surface (photosensitive surface) is the blade 21 that is pressed into contact with the drum surface (photosensitive surface).
The residual toner on the photosensitive drum 1 is cleaned by the VC, and the next cycle can be repeated again.

When such a copying cycle is interrupted and a predetermined number of copies have been completed, the document on the document table is ejected from the document table 2 by the conveyance device 27 in response to a signal from the if control device t (not shown), and the document is The document storage section 3 is removed by the collection device 28.
The top 1 of the unexposed originals 3 that are placed in

That's...! In addition to the copy 4t next to the overprint,
With the copy side facing up, the 1st negative numbers of the indicated number of sheets are stacked one after the other, and the 2nd negative numbers of the number of copies shown are clustered together...
The collection percentages are loaded in the order of ・・・・・・・・・・・・・・・. Therefore, after collecting both the 1st version and the copying materials, the order will be arranged! No need to fix it.

Furthermore, the copying machine according to the present invention has a device that exposes and copies both sides of the original and the copying material, respectively, while maintaining the correspondence between the two sides. (This will be explained in detail after reading the 11th flash.) No.11, all the JfL beaks that have been exposed to a predetermined number of sheets are collected by the document collection device 28 into the document storage section 3.
After the VC within 8 has been collected and all adjacent copy materials have been collected into the copy material storage section 32, the preset "1t11"
According to the command from 4'', a device (not shown) for detecting the remaining document j in the document storage section 38 sends a signal 1d to the 1IIIJ@ device (not shown), and the signal from this In!l # device is The information is transmitted to a separator drive device (not shown), and the separator 29 is released, and the collected photographic material 30 and the original feeding device
By releasing the separated cotton from 1t39, a state in which copying material can be fed by 30eM is created. Also, it is open at certain times.
The separator 29ri returns to its original position again in response to another signal sent from the i11 unit (not shown). This is to prevent the document from being fed with the original G4 feeder 1t39 even if the document for which double-sided copying has been completed is returned to the document storage section 38 again.

On the other hand, the separator 36 is moved from the storage position 1N (4-wire section) to the operating position (
It moves to the broken line part) and returns to its original position when it receives a signal that all other side copying has been completed.
This is to prevent the copy material from being fed by the copy material feeding device 40 when the copy material that has been copied (both 1 tl) is collected again into the copy material storage section 32.

Through the above procedure, a predetermined number of double-sided copies can be automatically made for each document in sequence, and the operation will be explained in more detail.

The iK single-sided or double-sided automatic continuous copying method above both takes into consideration continuity with a sorter, and in that case, the sorter automatically performs set alignment, greatly advancing the automation of copying work. be able to.

Next, a method of self-respect that allows the copying machine of the present invention to sort its own parts without using a sorter will be explained.

Figure 5 is a schematic diagram showing both sides of three manuscripts, namely 1
This shows the attempt to make two copies of pages 6 to 6. In a similar manner to this, A, it is possible to make as many double-sided copies of an arbitrary number of originals as desired.

Now, as shown in b(a-t) in FIG. 5, the originals are loaded in the document storage section 38 with the 1st, 3rd, and 5th sides facing upward from the top, and the switch on the main body operation section (not shown) is pressed. (not shown), switch the 1 printer to ``set copy'', specify the desired number of copies, and press the ``1a copy start'' button. Place the original sheet one by one at the exposure position It on the original platen 2. At this time, pages 2, 4, and 6 are each exposed once, and the original is placed as shown in (a-2). The document is collected in the upper part 30 of the document storage section 38. Next, a detection device t (not shown) detects that there is no document in the document storage section 38, releases the separator 29, and removes the document from (a-2''). L Tatsumi, who has been blamed for the situation, will be delivered in 1 day! Leads to t39. After that, the separator 29 automatically returns to its original position.

The original is exposed once each to 5-degree, 4-degree, and 1-degree exposure, and is collected in the stock (a-1) in the upper part 30 of the document storage section 38.

At this time, the copy material is collected in the copy material storage section 32 in a state as shown in (b-1). That is, 2 negative orders from the bottom 4 Sadabetsu
6-way 95-sada, page 3, page 1 facing upwards.

Moreover, the three sheets from the top and the three sheets from the bottom are stacked in opposite directions.

When the copying of one side of the U photo material is completed, the above-mentioned Haraaki Zanryo detection device operates again and operates the separators 29 and 36, and then the copy material storage section ff140 feeds the sheets one by one from above. Copy onto the other side of the copy material. That is, (a-
Since the documents stacked in the condition 1) are fed and exposed in order from the top, the copy material with the second negative value and the third negative value is copied on the first copy material where the first negative value is copied. 4 on the other side of the material
Sadame.

It is copied as follows...
The original is collected in the upper part 30 of the original storage part 38 as shown in (a-2), and the separator 29 is released again in the same way to continue copying. This time, the 5th negative mark is placed on the curved surface of the horizontal copying material where the 6th crest is copied, the 3rd negative mark is placed on the other side of the copying material where the 4th crest is copied. Copies are made in the order of . At this time, the document detection device (not shown) is activated again (~, separator 29.
36 to return to the original position and at the same time cut all the magnetic wires. In other words, if n is set when copying is performed, the separator 36 is activated when the separator 29 is released for the nth time, and when the separator 29 is released for the 2nth time, the VC- t parator 36
When the second operation of the 0 separator 36 is transmitted to the control device (lt, c (not shown)), this H-control device assists in cutting off all magnetic sources. It has become.

Now, after all the operations are completed, the operator takes out the copy materials loaded in the state (1')-2) from the copy material storage section 32, and changes the orientation of the bottom three copy materials. ,
You can obtain two copies made at the same time as the originally set original.

In this explanation, in step 1, it is assumed that the original is set as shown in (a-1) at the beginning, but even if it is set as shown in (a-2), the top and bottom and orientation of the copy material that has been copied on both sides will be incorrect. Double-sided copying and aligning are possible by simply reversing (b-2) and doing the other things in the same way.

This completes the explanation of the automatic feeding and recovery device for originals and copy materials, but next we will explain how to double-side fill a thick original such as a book.

In FIG. 1, the document feeder 27 is housed in the document feeder cover 41, and by lifting the handle 31, the document feeder 127 and the document feeder cover 41 can be removed.
move above the original platen 2, and the 14 sheets of books, etc.
A handwritten manuscript can be placed on the manuscript table 2. If this is the case, the power will be automatically cut off and operation will stop.

Here, we will explain the details of the rrafx operation, taking both sides of the book as copying material and the combination of ILC and copying.

Figure 6 is on the right: 1 white, 2 meat, 3 white, etc. of Tsunaki's book.
. . . is a schematic diagram when copying.

First, as shown in (a), make the book 241 meet the manuscript standards, set the number of copies to be printed, and press the ``Start Copying'' button. Similarly, the 4th tribute, the 6th @, etc.
. . ., the exposure is repeated until the end of the cycle. At this time, a predetermined number of Q photographic materials are collected in one group from the last page of D to J@, with the sixth, fourth, and second pages facing upward, respectively, as shown in (C).

Next, the direction of the copy material is rotated 180 degrees and stored in the state shown in (d) +-* to prepare for secondary feeding. At this time.

Rotate the orientation of the book by 180' as shown in (b), make sure that the first grain of paper matches the original standard, and press the 'Copy other side' button.

After copying the required number of sheets, similarly, go back to the next page with Kf4,
Exposure is repeated for the 5th, 3rd, and 1 negative eyes, and the @2 cycle is completed. At this time, the copy material is 1 as shown in (e).
A predetermined number of copies of the copying materials are printed with the negative number facing upwards, the 2nd @ mark on the back of the first negative number, and the 1st and 3rd marks facing upwards, and the 4th mark is copied on the back. The copying materials that are in stock are all in one sheet, ・・・・・・・・・・・・・・・ and b
It is stored separately.

In this way, by keeping the orientation of the original (book) constant during each cycle and by reciprocating between the first and last R rivers, there is less risk of erroneous operation, and double-sided copying can be easily achieved.

In the case of a book with a left side fA, by performing the first cycle in the state shown in (b) and the second cycle in the state shown in (a), the double-sided copy will be It is.

As mentioned above, in the copying machine based on the $ invention, (I)

(II) Copy the required number of copies of both sides of the original onto both sides of the copying material [(I), (it) can be moved with a sorter.

] (III) Copy both sides of the liC manuscript onto both sides of the copying material and arrange the required number of copies (ff) It has many functions such as copying one side and both sides of 14 hand manuscripts such as books, and moreover, (I), (II
), (If), the operator first sets the
Just select the pickling method and press the "Start 1st copy copying" button, and each copy will proceed automatically, and the copying process will automatically stop after copying is completed, making it an original unattended machine. It's a copy machine.

On the other hand, GV) has improved the conventional difficulty and elegance of matching the edge of a 14-hand manuscript to the manuscript standard on the manuscript table, and has also reduced the risk of erroneous operation.

In addition, the structure is simple, and the processing work is simple even in the event of a jam.

Next, the present invention will be explained in detail using the four circuit diagrams and timing diagrams shown in Figs. 7.8, 9, and 10.11.

Figure 7 is an electrical circuit diagram for single-sided and double-sided auto-shaping of sheet documents when all sorters are connected, and Figure 8 is its timing diagram. This is a timing diagram for single-sided and double-sided self-copying, and FIG. 10 is a timing diagram thereof. FIG. 11 is a circuit diagram for copying one side and both sides of a thick original such as a book. First, the operation when the sorter is connected will be explained with reference to FIGS. 7 and 8. In the figure, signal SI

I) For single-sided copying, place a predetermined number of sheet originals in the original document storage section 38, set the L, Copy & M selector to the desired number of sheets, and press the copy start button. [From the circuit diagram in Figure 7] When you press the copy start button, a copy start signal 8. generates a pulse and passes through the OR circuit 1 differentiating circuit C and the flip-flop g
When a pulse is applied to the 84 children (set) of
ely O) t+ circuit output sheet original drive signal S4
becomes H level, and the sheet document starts to be conveyed from the document storage section 38. In this case, flip-flop g has been reset in advance. The sheet original is transported and the sheet original + f4
After the trailing edge of the sheet original is detected by the detection element 43, a pulse is generated after T and paper cutting, and when it is applied to the reset input (1t) of the flip-flop g, the Q output becomes 1■ level and outputs the optical signal to the AND circuit. The other input of the AND circuit becomes H level in advance than the copy start signal SI, and the system drive signal S becomes L (level). When a pulse is applied to the reset input of flip-flop g, the Q output becomes Lo.
The level reaches W level, and the original document drive S4 also reaches the 140W level, stopping conveyance of the sheet original. Therefore, after the sheet document starts being conveyed by pressing the copy start button, it is detected by the sheet document trailing edge detection element 43, and at T8 seconds, the sheet document is stopped at the exposure position, and the optical system drive signal S and H level are used to stop the sheet document at the exposure position. The system starts and exposes the original.

The document exposure is performed according to the number of copies set in advance by the preset counter part a and the copy selector. In other words, when the preset counter part a sets a predetermined number of sheets using a copy selector (not shown) and presses the copy button, it is reset by the sheet original drive signal S4, and a count signal is applied by the optical system inversion signal SI0, and the When the system is driven and exposed, the count signal and the preset signal match, and the count signal g becomes H level.T4 seconds later, the pressure is 0, and the set input (S) to the flip-flop g is passed through the circuit b1 and copy circuit C. A pulse is applied to Q output Fi1 (level, Q output becomes Low level, optical system drive Fi is stopped, and the next sheet original is conveyed.

A predetermined number of copies of the same sheet original are made using the method described above, and the copies are stored in a sorter (not shown). The above operation is continued until all the sheet originals are conveyed, the remaining sheet original amount detection signal S is plowed, the last sheet original is copied a predetermined number of copies, and the count-up signal S is activated (6). In other words, when all the sheet originals are conveyed from the original storage section 38, the remaining sheet original Jl is ejected (no. Due to the optical system inversion signal S, ., the count-up signal Sl becomes H level and is applied to the other input of AND circuit C, and the AND MO output becomes H level and after T3 seconds K Exclusive
The output copy trough signal 86 applied to the input of the y-OR circuit 1 becomes H level, completing the copying operation, and the copied materials are aligned in the sorter in the number set by the copy selector. The last sheet document is stored in the document storage section supported by the separator 29 in T seconds.

(2) In the case of double-sided copying For double-sided copying when a sorter is connected, press the double-sided copy button (not shown) in advance and then press the copy start button. When the double-sided copy button is pressed, the double-sided copy signal S goes to the I level, and a pulse is applied to the set terminal (S) of the 7-lip flop f through the differential circuit de+M, and the output Q of the flip-flop f goes to the H level, which is the input to the AND circuit. It is connected to the. First, when a predetermined number of double-sided copies of a predetermined number of sheet originals are to be copied, the predetermined number of copies is set using the copy selector (not shown), and for one side of the sheet original, the series of operations described in I) is performed, and when one side UkJ copying is completed, a count-up signal is generated. S, and the sheet document remaining stitch detection signal S both become H level, so the output of A N D lil path C becomes 1.
Exclusive after 13 seconds of rubber toner delay circuit
y Applied to the OR circuit and AND circuit. The other input of the AND circuit becomes 1 level due to the flip-flop f set in advance, and the output also becomes 1 level. The output of the AND circuit is the separator 29, 36 drive signal S, which is connected to the reset terminal (a) of the flip-flop f through the input of the exclusive OR circuit H1,j and the delay circuit T. When the output separators 29 and 36 drive signals S of the ANI) circuit go to H level, the inputs of Exclusively OR circuits r and j both become HL/Bell, respectively. J output sheet original drive 1M number S4 copy stop signal S6 is Low
level and further resets the flip-flop f) 1
A pulse delayed by 11 seconds is applied to the 4th child (11(,) through the delay circuit T. Therefore, in double-sided copying, when one side of the sheet original has been copied, the copying process is not stopped, but the conveyance of the sheet original is stopped. Separator 29.3
6 at the same time to complete the preparation for restoring one side of the sheet original. The operation for copying on the other side is the same as the one-sided copying described above, but when the last count-up number S occurs, the flip-flop f has already been set to 29.36. Since it is reset by the signal S, the output Q becomes a low level, and the output Q becomes a low level due to the AND circuit.The separators 29 and 36: the drive signal S remains at a low level and is copied without being disturbed. The stop signal S6 generates a pulse to stop copying and complete all copying operations.In this case, the sorter (not shown) does not store copy materials that have been printed on one side, but only copies that have been copied on both sides. It will be stored.

Next, see Chapter 9 regarding the double-sided automatic copying method when aligning copies.
．． This will be explained with reference to FIG. The names and symbols of parts in the circuit diagram FIG. 9 and the timing diagram 410 are the same as in FIG. 7.8 described above.

■) Double-sided automatic copying method when copies are aligned Same as in n), press the double-sided α4 button in advance, set the number of copies you want to align using the copy selector (not shown), and place a predetermined number of sheet documents in the document storage section 38.

The ANDN0 circuit power remains at the Low level until it is detected and reaches the F■ level.

The above-mentioned operation is performed for the predetermined number of sheet documents set in the document storage section 38, and the last sheet is placed in the document storage section 38.
When the sheet original is conveyed from 1 to 3, the shallow soak detection S becomes H level and a pulse of the optical system reversal signal Stt is generated.
A nox pulse occurs in the output of the ND circuit and becomes a count signal for the preset counter part a. On the other hand, the pulse is delayed by 1r seconds by the delay circuit Ill and sent to the separator 29# @signal S16 and gx exclusive
ly OJ, applied to the L circuit quantity. In other words, unlike the cases I) and It) above, each sheet original is exposed to light on one side of the sheet original, and after tr seconds from the reversal of the optical system that exposed the single-sided sheet original, all the sheet originals are separated by the separator 29. The document is stored in a separate document storage section.

From the output Q1c of F'-Fg that has been set, separator 2
fdx by 9 drive signal 810 and optical inversion signal Sat
Since both the inputs of the OR circuit are at H level, the output n goes to Low level and conveyance of the sheet document is stopped. At the same time, the separator 29 is driven and the other side of the sheet document is stored in the document storage section 38 in a dazzling manner. Through the series of operations described above, four lights are emitted in the curved direction of the sheet document. Therefore, when the n part is set by the copy selector and the separator 29 operates for the nth time, the count up signal S is generated.

The force is generated and the delay circuit uTs is AND circuited and Excel
A pulse is applied to the input of the usivelyOR circuit l. The other input of the AND circuit is connected in advance with the double-sided copy signal S, so that the output Q of F-Fg becomes H level.
Therefore, the output of AND1gl becomes H level when the count up signal Ss is generated.
ly OR circuit quantity input, separator 36 @ motion signal S,
1. The reset counter reset signal 'L' is delayed by 4 seconds and is reset as Pl and k'f reset No. 11, respectively.
t is applied ○ Therefore, when the separator V-taper 29 operates for the nth time, the separator 36 is activated, the preset counter is set, and F-Ii'f is reset after 11 seconds. TomoH
level, the copy stop signal S6 is not generated and copying continues, and when the separator 29 operates for the second time, a count up signal is generated and the delay circuit T If
The copy stop signal 8s is transmitted through the lxclusively OR circuit to stop all copies. In this case, the 2nth count-up signal S, keAN
I) The output of 'f' is applied to F-, which is the input for the ANDN0 circuit, and the separator 36IiA' is applied to the power of the circuit.
1JJJ 17 seconds after the occurrence of 8° due to the delay circuit T! '-1! Since the above pulse is applied to the reset terminal (R) of 'f, it becomes LOW level and A
Since the output of the ND circuit remains at a low level, the separator 36 drive signal S I+ and the reset signal for the preset counter part a are not generated. , Figure 10 is a timing diagram of one copy of three sheet originals partially double-sided copied.

(2) This will be explained with reference to FIG. 11, which is a circuit diagram for copying one side and both sides of a thick original such as a book. First, as shown in (a), match the second negative side of the book with the original standard, set the desired afin section using the copy sector, and press the ``y'' button to start copying 1d-i4FS.

is generated and is applied to the set terminal (8) of F - )" f through the differential circuit e and is also applied to the reset terminal (8) of the preset counter part a.
Output of Fn Q1 optical system drive pair S, t) (level), the optical system is driven and the sheet original is exposed 0 times.In addition, the optical system reversal signal 81G causes the preset counter part a
Since it supplies count 18 to , the second negative IJij
'In contrast, when the optical system is reversed after the n-th exposure, a count-up signal Ss is generated and copying is stopped. At the same time, it is also applied to the reset terminal (R) of bl and Fn, and the output Q is at a low level. The optical system drive then stops. Similarly, page 4, negative number 6, etc.
Exposure is repeated in order to complete the first cycle (single-sided copying). Next, rotate the orientation of this prayer photo material by 180 degrees as shown in Figure 6 (
Restore it to the state of d) and prepare for secondary feeding. At this time, the direction of the book is also rotated by 180 degrees as shown in FIG. 6(b), the last four lines match the document standard, and the copy start button is pressed.

After copying the required calyx crest (part n), do the same! The first cycle is reversed, the fifth page, the third page, and the first page are repeated, and the second cycle (double-sided copying) is completed.

If a sorter is attached to perform the above series of operations, further sorting can be achieved.
