Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to copying, and more particularly, to a copying machine equipped with an automatic document feeder (hereinafter referred to as ADF) and a copied paper processing apparatus (hereinafter referred to as finisher). This is related to copying.

(Prior Art) Conventionally, there has been a copier equipped with an ADF and a finisher.

The ADF has the ability to sequentially feed a large number of originals onto a contact glass serving as an exposure section, and two modes are possible for this original feeding mode, for example.

One of them is a circulation automatic feed mode (hereinafter referred to as RADF mode) in which documents are automatically fed in circulation. This mode is convenient for obtaining a predetermined number of copied sheets (hereinafter referred to as copied sheets) one by one in page order, and the copy cycle (exposure scanning) corresponding to one copy is performed for one original. This is executed in combination with a copy process that is repeated a predetermined number of times.

The other one is a one-bus automatic feed mode (hereinafter referred to as ADF mode) in which documents are automatically fed in a non-circular manner. This is a convenient mode for obtaining a predetermined number of copies of the same original in a sorted manner.The original is intermittently fed one by one to the exposure section, and the This is performed in combination with a copying process in which the original is replaced with the next original after a predetermined number of copy cycles have been performed on the original.

For example, two modes are possible for the finisher.

One of these is the doggy tail mode, in which the copied sheets are sorted one by one for each original using a rocking table that intermittently oscillates the copied sheets.
This is a stapling mode in which a predetermined number of copied sheets are automatically bound using a binding device (for example, a stapler under the trade name).

In this way, in the conventional copying machine, in the above example, a total of four selection combination modes are possible: two mode selections for the ADF and two mode selections for the finisher.

In the case of an ADF, when the specified number of copies corresponding to the required number of copies is set on the display section, the number of copies corresponding to the number of processed copies is sequentially displayed in synchronization with the copy number display provided on the display section. . Further, when a document exchange operation is performed, the copy number display once displays 0, and then the copy number corresponding to the processed number of copies is displayed on the copy number display again. Furthermore, the number of original sheets displayed is displayed on the original sheet number display to indicate the number of original sheets being processed.

On the other hand, in the case of the RADF mode, the number of processed copies is generally displayed on the copy number display. In this case, the number of displayed sheets will not change until one copy of the document is completely processed. For this reason, the above A
Differences from the display format of the DF mode cannot be accurately grasped, which often causes problems in operation.

Furthermore, in the RADF mode, when managing copy fees, etc., the number of copies must be calculated from the number of originals and the instructed number of copies, which is extremely troublesome.

(Purpose) Therefore, an object of the present invention is to provide a copying machine that allows each copying operation in RADF mode and △DF mode to be accurately and easily known and to perform the operations well. .

(I) In order to achieve the above object, a copying machine according to the present invention includes a set number display that displays the specified number of copies or the number of copies, and a copy number display that displays the number of copies or copies that have been made. , a document number display that displays the number of processed document sheets, and a total copy number display that displays the total number of copies.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 12, a contact glass 200 is provided at the center of the upper surface of the copying machine main body 2. As shown in FIG.

Then, AD so as to cover this contact glass 200.
F6 is installed. Further, a finisher 8 is connected to the left side of the copy number main body 2 in the drawing.

To give an overview of the configuration and operation of ADF6, first
The DF6 is capable of a pressure plate mode in addition to the ADF mode and RADF mode described above. The pressure plate mode is a mode when a document is manually set on the document table, and in order to adapt to this mode, the ADF 6 is provided so as to be able to swing toward and away from the contact glass 200 with one end serving as a fulcrum. .

In FIG. 13, which shows details of the ADF 6 in an enlarged manner, the symbol @601 indicates a belt. This belt 601 has the function of sandwiching the original together with the contact glass 200 and transporting the original using its transport force, and also functions as a reflection plate and a pressure plate. On the right side of the belt 6C) 1 in the drawing, a document table for receiving documents is provided in two stages, upper and lower. The upper document table is designated by 602, and the lower document table is designated by @603.

The paper feeding operation in the RADF mode is as follows. The original G is set on the original table 602 with the image side facing up. The document table 602 is provided with a document sensor S1 as a detection means for detecting the presence or absence of a document. and,
When the setting of the document G is detected by the document sensor S1, the first mode selection key (switch SW1 or switch SW3, etc. described later) is used to select the RADF/ADF mode.
If no mode is selected, automatic fishing is selected, RADF mode is selected for ADF, and stable mode is selected for finisher. Then, when the print switch is turned on, the copying process begins. When the paper feed roller 605 is rotated clockwise, the bottom original is separated and turned along the guide #fi, 606, and when feeding paper, it rotates counterclockwise. The document table 6 is moved by the paper refeed roller 607.
Guided to 03. Therefore, the image plane is downward.

Then, when the rear end of the document passes a document sensor S2 provided on the document table 603, the rotation of the refeeding roller 607 is stopped, and then the reverse rotation is started and the document is guided to the contact glass 200. When the original is guided to the contact glass 200, the belt 601 begins to rotate clockwise, and the conveyance of the original is taken over by the belt 601.

Note that the scanner 202, which includes the exposure lamp 201 and the first mirror ML1 as some of its components, is normally positioned at the first home position H, which is the left end of the contact glass 200.
However, at the time this document is sent to the document table 603, it has already moved to the second home position HP2, which is located to the right of the contact glass 200, and remains stationary.

Therefore, as the document moves to the left in accordance with the rotation of the belt 601, exposure is performed by the stationary scanner 202. At this time, at the same time that the trailing edge of the first document comes off again, the next document starts to be fed from the document table 602 to the document table 603. Thereafter, the above operations are repeated.

The so-called copied original that has been exposed is placed on the belt 6.
01, the document is sent to a reversing roller 609 and a guide 610, where it is turned, passed over a belt 601, and guided onto a document table 602.

A reversal sensor S3 provided at the guide 610 is used to check for abnormalities in document conveyance. The copied originals are stacked -H on the original stop plate 611 which is rotatably provided on the original platen 602, and are kept on standby until all the remaining originals are copied and fed here. It has become. When copying is completed, the document stop plate 611 is rotated clockwise to release the document from stopping, and the - set of documents is dropped onto the document table 602, allowing the next copying process. The above is an outline of the operation of the ADF in the RAD F mode.

Next, an overview of the operation of the ADF in the ADF mode will be explained. In the ADF mode, the finisher automatically selects the doggytail mode. In the RADF mode, as described above, the scanner 202
The scanner 202 is in a stationary state at the home position HP2, and the original is moved relative to it to perform exposure, but in the ADF mode, the scanner 202 is at the first home position HPI before starting the copying operation.

Then, the document is transferred from the document table 603 to the contact glass 2
After waiting for the leading edge of the document to be conveyed to the first exposure reference position @SP1, which is a predetermined position on the contact glass 200, the scanner 202 starts exposing the document while moving to the right. is started. The document is held still while being exposed. After the scanner 202 moves to the right to a predetermined distance that matches the exposure of the original, it turns and returns to the first home position 1-IPl, and exposure scanning is repeated for the required number of copies specified for the same original. . Note that in the figure, the symbol SP2 indicates the movement end position of the scanner 202. After the exposure has been completed in this way, the original is transferred to the reversing roller 609 and the guide 610.
is reversed, passes over the belt 601, and passes through the guide plate 606.
The documents are stacked at the document stop plate 611 via the document stop plate 611.

Next, the configuration and operation of the finisher will be outlined.

The finisher 8 uses the copy outlet 20 of the main body 2 for copying.
The entrance is located at 3.

A roller 801 is arranged near this entrance, and a switching pawl 802 is provided immediately behind it.

The switching pawl 802 is provided so as to be selectively swingable about the axis between the position shown by the solid line and the position shown by the imaginary line.

In the position shown by the solid line, a passage to the paper tray 803 is formed, and in the position shown by the imaginary line, the stapler
A passageway to 804 is now formed.

When the stable mode is selected for this finisher 8, the copied paper is fed into the finisher 8 from the copy outlet 203. At this time, the switching claw 802 is turned on and is moved to the position of the imaginary line, and the copied paper is guided toward the stapler 804 by the switching claw 802. When the most shrunk paper passes the sensor S4 provided immediately before the stapler 804, it is aligned by a paper aligning device (not shown), and then the - set of copied paper is automatically processed by the stapler 804. It is bound.

The stack of copy paper bound in this way is transported by the feed roller 80.
5, the paper is returned to the conveyance path again, and is discharged to the paper tray 803 via the paper discharge sensor S5.

Next, a case will be described regarding the finisher 8 when the doggy tail mode is selected.

The copied paper is fed into the finisher 8 from the copy outlet 203. At this time, the drive mechanism of the switching claw 802 is turned off and is at the solid line position. Therefore, the copied sheets advance straight and are stacked on the paper tray 803. When a predetermined number of copied sheets of the same original are stacked, the position of the paper tray 803 is changed within the paper placement plane. That is, as shown by arrows in FIG. 14, the paper tray 803 is alternately switched between the solid line position and the imaginary line position. By such a doggy tail operation, the copied sheets are alternately stacked on the paper tray 803 and sorted into predetermined number of sheets. When the doggy tail mode is selected in the RADF mode, the position of the paper tray 803 is switched for each copy of the original set on the document table, so even if you do not want to bind the pages, you can arrange them in the order of the pages. .

Next, regarding the copying machine main body 2, an electrophotographic copying machine with a membrane structure can be applied to this. The outline is as follows.

The light image of the original illuminated by the exposure lamp 201 is
Mirror ML1, second mirror ML2, third mirror ML
3. Photosensitive drum 20 via fourth mirror ML4, fifth mirror ML5, sixth mirror ML6 and lens 204
5.

In the pressure plate mode and ADF mode, the exposure lamp 201
Exposure scanning is then performed by shifting the first mirror ML1 by a stroke amount corresponding to the document size. At this time, in order to maintain the optical path length up to the lens 204 constant, the second mirror ML2 and the third mirror ML3 are moved by 1/2 of the stroke of the exposure lamp 201 and the like.

A main charger 206, a developer 207, a transfer charger 208, a cleaning device 209, and the like are arranged around the photoreceptor drum 205 in the order of its rotational direction. Further, in the figure, numerals 210 and 211 each indicate a paper feed section, and copy paper of different sizes are fed to the paper feed roller 21.
The paper is fed out by the rotation of the paper feed roller 210B and sent toward the photosensitive drum 205 via the registration roller 212. Then, the toner image is transferred by the transfer charger 208 and sent to the fixing device 218 by the conveyor belt 213, where the image is fixed. After that, copy output port 2
03 to the finisher 8.

In the case of double-sided copying, after being reversed through the reversing guide 214 and the double-sided intermediate tray 215, the toner image is transferred to the back side through the registration rollers 212 again.

In order to confirm the arrival or presence of copy paper in the conveyance path, a registration sensor S6 is provided immediately before the registration roller 212, and a paper ejection sensor S7 is provided immediately before the roller 216 provided immediately before the copy ejection port 203.
is provided.

The above is an overview of the copying machine itself. Next, the operation panel will be explained.

The configuration of the operation panel is shown in FIG. The operation panel 250 is provided on the upper surface of the copying machine main body 2 at any location suitable for operation.

The switch SW1 is a mode selection key for specifying the ADF mode, the switches S to v2 for the doggy tail mode, the switches S to ■3 for the RADF mode, and the switch SW4 for specifying the stable mode. switch SW1
And switch SW3 is the mode selection first key, switch SW2t3 and switch SW4 are the mode selection second key.
It's called a key. In addition, the LP provided in the L section of each switch
I to LP4 are indicators that light up when the switch is turned on to notify that the mode is designated. Lamp Pl, LP3 as the first indicator, lamp LP
2. LP4 is called a second display. The switch groups S to v5 are switches for specifying scaling factors such as enlargement and reduction, for example.

Reference numeral 260 indicates a display section, the details of which are shown in FIG. In FIG. 1, the number of copies specified by the key input by the operator or the number of copies is displayed in the segment ``Number of Copies'' display section. Further, the number of processed copies or the number of copies is sequentially displayed in the "number of copies" display section. Further, the upper counter display section 261 is composed of, for example, a 40-character display consisting of 5×10 dots and a CD. On the left side, the number of processed originals is displayed sequentially as ``Genkou Maisuu'', and on the right side, the total number of copies is displayed as ``Number of copies''.
"Total Copy" is displayed sequentially.

For example, if three copies of a five-page original are specified and one copy has been copied, the display will be as shown in FIG. 2. That is, the number of copies set is "3" and the number of copies processed is "1".

At this time, the "Complete completion" display is "5" and the "Total copy" display is "5". In this case, the "number of set sheets" means the number of sets, and the "number of copies" means the number of copies.

At the point when the specified three copies have been copied, the "number of copies", that is, the number of copies, is "
3" is displayed, and the "total copy" display is 5 times the number of originals x 3 copies, resulting in a total of 15.

Next, the control system of the copying machine according to this example will be explained with reference to the block diagram of FIG. 15. The main control section 270 comprehensively controls everything including the copying machine main body 2, ADF 6, and finisher 8. This main control section 270 is equipped with a microcomputer, and is in charge of controlling the ADF6.ADFi+11'! ] section 271, operation panel 2

It includes 18 heat sources and an exposure lamp 201. Also,
The main control unit 270 receives various signal groups 275 generated according to the copy process.

Other features include a sensor S8 as a detection means for detecting the presence or absence of staples in the stapler 804, a registration sensor S6, a switch SW8 for manually binding paper, a stable limit release switch SW9, and a stable solenoid for paper binding. 5QL3, solenoid 5OL4 for driving the switching claw 802, sensor S4 that detects the arrival of copy paper to the stapler 804, paper discharge sensor S5 that detects the arrival of copy paper to the paper tray 803, paper tray 803
The doggy tail motor M6 that swings the doggytail motor M6 and the like are also under the control of the main control section 270.

Next, the copy process will be explained according to the flowcharts shown in FIGS. 5 to 11.

First, in FIG. 5, in the Fl phase, the original platen 6
It is checked whether an original is set in 02. If document sensor S1 detects the presence of a document, F2
The process bypasses the phase F3 and proceeds to the phase F3, where it is checked whether the stapler 804 has staples for paper binding. If there is a needle, RADF mode and stable mode will be automatically selected, and this will be indicated on the operation panel 250.
is displayed by the lamp LP. If it is determined in phase F3 that there are no staples, then in phase F16 the state of staples out of the stapler is displayed on the operation panel 250 and other appropriate parts, and a warning to replenish the staples is given. Further, since the stapler 804 cannot perform paper binding due to the lack of staples, the RADF mode and the doggy tail mode, which does not require staples, are selected in phase F17, and a message to that effect is displayed on the operation panel 250.

Note that even if no rp or manuscript is set on the document table in phase F1, the RADF mode is set to switch SW.
3, mode setting and display according to phase F4 or phase F17 are performed after phase F3, depending on the presence or absence of the hands.

Then, in phase F5, it is checked whether the ADF mode has been selected. Here, if the ADF mode is designated by switch SW1, the mode setting and display in phase F17 are changed to ADF mode in phase F6.
The set is switched to F mode and doggy tail mode and displayed.

Alternatively, if there is no document set, a new process of phase F6 is performed.

Next, in phase F7, it is checked whether the doggy tail mode is selected. If the doggytail mode is not selected, the doggytail mode is set and displayed in phase F8.

If it is determined in phase F7 that the doggy tail mode has not been selected, it is checked in phase F9 whether or not the stable mode has been selected. If the stable mode is selected here, the process moves to phase F10, where it is checked whether the RADF mode is selected. If the RADF mode is selected, a check is made in phase F11 to see if there are any staples in the stapler, and if there are no staples, no staples are displayed in phase F18, and the process moves to phase F13. If there is a needle, stable mode is displayed and set in phase F12.

On the other hand, if it is determined in phase F9 that the stable mode is not selected, the process immediately moves to phase F13. Furthermore, if it is determined in phase F10 that no RADF mode is selected, the process also moves to phase F13.

Phase F13 is a subroutine for checking other human power. That is, since there may be cases where the temperature of the fuser 218 is set, the copy magnification is specified, and the mode is manually specified using each switch on the operation panel 250, the settings in phases F5, F7, F9, Flo, etc. The mode has been checked repeatedly. When the other manual checks are completed in phase F13, the state becomes copyable in phase F14.

Next, in phase F14, copying becomes possible, and when the print switch SW7 is turned on, the process shifts from phase F15 to phase F19 in FIG. 6.

If RADF mode or ADF mode is specified, a subroutine for document processing mode is executed in phase F20.

Here, the subroutine of the "original processing mode" (see FIG. 7) will be explained.

When print switch SW7 is turned on, phase F2
At 01, the motor M3 starts driving, and as a result, the paper feed roller 605 rotates to transfer the original on the original platen 602 to the original platen 60.
Start sending it to 3.

The motor M3 is turned on when the document sensor S2 detects the document, and then stops driving when it is determined in phase F202 that the paper has been sufficiently fed onto the document table 603 and turned off ( Phase F203). In this way, if the document sensor S1 is still turned on at the time when the document is sent to the document table 603, this indicates that the document still remains on the document table 602. If the document sensor S1 is off, it can be seen that there is only one document on the document table 602.

If there is only one document, ADF mode is sufficient and RADF mode is not necessary. Also, there is no need to set it to stable mode. Furthermore, if the RADF mode and stable mode are executed when there is only one original, a large amount of time will be spent transporting the original and copy paper. Therefore, in phase F204, it is determined whether the document sensor S1 is on or off, and when it is off, since there is only one document, the setting and display of the RADF mode and stable mode are canceled in phase F206, and the phase
In step 207, the ADF mode is set and displayed. Note that when the document sensor S1 is on in phase F204, since there are at least two documents, the process proceeds to phase F2O3, which is the "move scanner to HF2" subroutine, and moves the scanner 202 to the RADF mode. 2 home position HP
Move to 2.

Here, the "Move scanner to HF2" subroutine (
Fig. 11) will be explained.

In phase F2051, the motor M5 for driving the scanner 202 is turned on to move the scanner 202 forward, that is, to move to the right, and the scanner 202 turns on the switch 5W.
11, motor M is turned on in phase F2053.
5 and positions the scanner 202 at the second home position HP2.

Returning to FIG. 6, in phase F21 it is checked whether or not the RADF mode is in effect. If “no”, phase F22
Then, it is checked whether the mode is ADF mode.

If "No" here, the mode is the normal pressure plate mode, and the process moves to phase F26, where copy routine 1 is immediately executed. This copy routine 1 is a well-known copy processing routine, and includes paper feeding control of copy paper from the paper feeding unit 210 or paper feeding unit 211, device control around the photosensitive drum 205, control around the scanner 202, etc. . However, at this time, the scanner 202 uses the first home position HP1 as a reference position and performs exposure scanning by the length of the original inputted in phase F13 and the length determined by the magnification ratio.

When "copy routine 1" is executed in phase F26,
"1" is added to the copy counter 1 that counts the number of processed copies (phase F27), and
The contents of the copy counter 1 are displayed on the "number of copies" display section in the display section 260 in FIG.
The contents of copy counter 1 are displayed in the "total copy" display section inside.

Thereafter, a copy cycle is performed until the contents of the copy counter 2 and the "set number of sheets" match. The copy cycle ends when both values match, and phase F28
Then move on to Phase 29.

At this time, if doggytail mode is specified, the "doggytail movement" subroutine (
(described later) is executed. If doggytail mode is not specified, the process advances to phase F31. If the doggy tail mode is specified, the process moves to phase F31 after moving the doggy tail, and if it is the pressure plate mode, all copying ends here. If the mode is ADF mode, the process returns from phase F32 to phase F23.

If it is determined in phase F22 that the mode is ADF mode, the process also proceeds to phase F23, where the subroutine of the document transport mode is executed. Here, the subroutine of the document transport mode (see FIG. 8) will be explained.

Here, as described above, the first document set on the document table 602 has already been set on the document table 603, so the processing starts from here.

First, in phase F231, the motor M1, which is the drive motor for the belt 213, is turned on, and in phase F232, the drive motor M4 for the paper refeed roller 607 is turned on. As a result, the original is transferred from the original table 603 to the contact glass 200.
sent towards. Then, when the leading edge of the document turns on document sensor S2, phase F233 to phase F
The process advances to step 234, where "1" is added to the count value of the document counter, and its contents are displayed on the "Complete" display section of the counter display section 261 in FIG. after that,
Proceeding to phase F235, the count value of the document counter becomes "3".
0" is checked.

If the count value of the original counter is "30" here, the "original 3° signal" is turned on in phase F244. This "30 originals signal" is necessary information in the stable mode subroutine (see Figure 9).
This routine will be explained later.

Next, the process moves to phase F236, where it is checked whether the mode is RADF mode. Since the ADF mode is assumed here, the process advances to phase F238. Now, when the document is sent further toward the contact glass 200 from the document table 603 and its trailing edge passes the document sensor S2, the document sensor S2 is turned off. Once the document sensor S2 is turned off, the rotation of the paper refeeding roller 607 is no longer necessary, so the motor M4 is turned off in phase F239.

Next, in phase F240, the presence or absence of a document on the document table 602 is checked by the document sensor S1, and if there is a document, the drive motor M3 of the paper feed roller 605 is turned on in phase F241, and the aforementioned phase F201 ( 7), feed the original onto the document table 603 (phase F242) and turn off the motor M3 (phase F2).
43).

If it is determined in phase F240 that the document is not on the document table 602, the process advances to phase F245 and the "document end signal" is turned on.

Returning to FIG. 6, when the subroutine of the document transport mode in phase F23 is completed, the motor M4 is turned on to drive the paper refeeding roller 607, and after a predetermined period of time after the document sensor S2 is turned on, the subroutine in phase F23 is completed. Then, the original is set on the contact glass 200 [Original set OKJ]
give a signal.

Then, in phase F25, the phase F23
1 (see FIG. 8) is turned off, and the document is stopped at a predetermined exposure position on the contact glass 200.

Thereafter, when a predetermined number of copies have been completed through phases F26 to F29, etc., if the mode is the doggy tail mode, the process moves to a "doggy tail movement" subroutine of phase F30, and the paper tray 803 is moved. If it is not the doggytail mode, copying is repeated until the end of the original through phase F31.

Here, the "doggytail mode movement" subroutine (
(see Figure 10) will be explained.

If it is the doggy tail mode, the process moves from phase F301 to phase F302, and the presence or absence of the "normal rotation flag set" is checked. If the normal rotation flag is not set, the doggy tail motor M6 is set to t in phase F303.
The sheet tray 803 is driven in forward rotation for a second to move the paper tray 803 from the existing position to the opposite side, and to set the forward rotation flag. If it is determined in phase E302 that the forward rotation flag is set, in phase F304, the doggy tail motor M6 is driven in the reverse direction for t seconds to move the paper tray 803 from the existing position to the opposite side, and to rotate forward. Reset flag. That is, the paper tray 803 swings left and right by a fixed amount a to sort a predetermined number of copied sheets.

Returning to FIG. 6, after executing the "doggy tail movement" routine, if in ADF mode, the process goes through phase F31 and then phase F.
At step 32, it is checked whether or not the document is finished, and if it is, the above-mentioned operation is repeated, and if not, the process ends with one pass of the document.

Next, the RADF mode will be explained.

If the RADF mode is designated, in FIG. 6, the process moves from phase F19 to phase F20, a subroutine of "original processing mode".

Then, when the RADF mode is confirmed in phase F204 by the ON state of document sensor S1, the scanner 20 is activated in phase F2O3 as described above.
2 is moved to the second home position HP2 and remains stationary.

This completes the preparation for a so-called sheet-through mode in which the scanner 202 is held stationary while moving the original for exposure scanning. Here, the reason why the scanner 202 was moved to the second home position HP2 near the document table is to shorten the processing time as much as possible, and to move the scanner 202 to the second home position HP2, which is located near the document table, in order to shorten the processing time as much as possible. 61
This is to prevent the conveyance speed (scanning speed) of the document from changing after passing through the inversion section due to zero.

Now, when phase F20 related to the subroutine of "manuscript processing mode" is completed, in phase F21, RAD
It is checked whether the mode is F mode or not, and since it is the RADF mode, it is checked in phase F33 whether or not it is the stable mode. If it is not the stable mode, it is the doggy tail mode, and the process eventually moves to phase F53.

In the stable mode, the staple condition of the stapler 804 is checked again in phase F34. here,
The reason why the needleless check is performed is that this special operation restarts from this point after copying one copy of the original. If there is a staple, the process moves to phase F35, where the solenoid 5OL4 of the switching claw 802 is turned on to move it to the position shown by the imaginary line in FIG. 12, thereby forming a conveyance path to the stapler 804. Thereafter, the process moves to phase F35.

If it is determined that there is no needle in the above phase F34, the absence of a needle is displayed on the operation panel 250, etc. in phase F49, and the solenoid 5OL4 for the switching claw 802 is turned off, and the switching claw 80
2 in the position shown by the solid line, the path to the paper tray 803 is secured, and the doggy tail mode is automatically set (phase F51). This is because there is no staple, so if the paper is sent to the stapler 804 without binding, the paper will jam when it is ejected.

If there is a staple, the process moves to phase F35 and executes the "original transport mode" subroutine (see FIG. 8), as described above. Here, the refeeding of the original is similar to the operation in phase F23 in the ADF mode described above, and after adding "1" to the original counter in phase F234, it is checked in phase F235 whether or not it is the 30th original. is checked. If it is the 30th sheet, the original 130 signal is turned on in phase F244, and the process moves to phase F236. Here, since the mode is RADF mode, the paper restart signal is turned on in phase F237. This phase F23
7 is related to copy routine 2 (phase F37) of main 70- in FIG.

In other words, in the copy routine 1 of phase F26, after the copy paper is fed, the registration roller 212 shown in FIG. After a lapse of time, a start signal is obtained and the registration roller 212 is restarted. This timing adjustment allows the toner image on the photosensitive drum 205 to be aligned with the copy paper during transfer.

However, in RADF mode, the scanner 202
The home position HP2 is fixed, and unlike the copy routine 1 described above, the timing for restarting the registration roller 212 cannot be obtained based on the start signal generated in conjunction with the movement of the scanner 202. Therefore, as a signal in place of the start signal, the original sensor S2
The signal when is turned on is used as the paper restart signal. This is the reason why the copy routine F37 is provided.

Now, in FIG. 8, when the document sensor S2 is turned off in phase F238, the motor M4 is turned off in phase F239 to stop the paper refeeding roller 607, and if the document sensor S1 is turned on at that time, the next The original is set on the original table 603 in the same way as in the ADF mode () needs F241, F242, F243>.

When this process is completed, "copy routine 2" is executed in phase F37 of FIG. This copy routine 2 is
As mentioned above, the only difference is that copy routine 1 is different from the paper restart part and that the document is moved and exposed relative to a fixed scanner; other than that, the copy process is similar to that in pressure plate mode/ADF mode. do.

When the copy routine 2 ends in phase F37, the copy counter 2 is incremented by "1" in phase F38, and the value is displayed as "1" on the counter display section 261 in FIG.
"Total Copy" display area.

Next, in phase F39, it is checked whether the mode is stable mode. Here, if it is not stable mode, it is doggy tail mode. If it is in the stable mode, the process advances to phase F40, where it is checked whether the stable limit release switch is turned on.

This stable limit release switch is a DIP mill switch as one of the various key switch groups SW shown in FIG. If this switch is on, it indicates that the stable limit, for example 30 pages, has been lifted, and
"Signal on" is not checked and phase F42 is turned on.
After repeating the process starting from phase F33 and copying until the number of sheets set on document table 602 is completed, in phase F43, paper binding for one copy of the original is performed.

Here, Hara! The reason why the restriction of 30 sheets may be lifted is because if the copy paper is thin, binding of 30 or more sheets may be possible.

If the stave limit release switch is turned off in phase F40, it is assumed that the stapler cannot staple more than 30 sheets of paper, so it will temporarily stop copying after copying the 30th sheet of the original. After that, copies exceeding 30 sheets are bound in the same manner.

Normally, regardless of whether the stable limit release switch is turned on or off in phase F40, the document counter remains in phase F4.
Unless the "30 originals signal" is turned on in step 1, the process moves to phase F42. Copying is continued until the document sensor S1 turns on the document end signal indicating that there is no document on the document table 602 (however, the document stop plate 611 has finished copying and the paper is stopped). "
Move to "stable mode".

Here, the "stable mode" subroutine (see FIG. 9) will be explained. At this stage, copying of one copy of the original has been completed.

When the last copied paper turns on and then turns off the sensor S4 that detects the arrival of the copied paper to the stapler 804, that is, when the copied paper passes the sensor S4, the process shifts from phase F431 to phase F432. , the paper is aligned along with other copied sheets already stored in a paper alignment device (not shown). Since the document end signal is turned on in phase F42, the document remaining signal is turned off in phase F433, and therefore, in phase F434, the stable solenoid 5OL3 is turned on to perform paper binding.

Note that if there are 30 or more originals and therefore it is necessary to paper-bind one set of originals in two or more copies, the stable limit release switch is turned off in phase E40. Proceed to phase 41 from
After waiting for the "30 originals signal" to be turned on, the process shifts to the stable mode of phase F43.

In this case, if there are 30 originals, phase F4 in Figure 9
33, the document remaining signal is off, so phase F4
Paper binding with 34. If the manuscript exceeds 30 pages,
It is determined whether or not to perform paper binding depending on whether the remaining number of sheets is one or two. When there is only one manuscript left,
This is because it is pointless to paper-bind the corresponding copy paper.

Therefore, to determine that, phase F433
If there is a remaining original signal in phase F422, the flag for the remaining original signal is turned off, and then in phase F4
At step 33, it is determined whether the value obtained by subtracting "30" from the count value of the document counter is "1". The above value is "1"
If not, the stapler 804 senses that there are two or more copies of less than 30 sheets, so the process proceeds to phase F434, performs paper binding, and then...
Phase F435) in which the ejection feed roller 805 is rotated and sent out.

If the value in phase F443 is determined to be "1", the stapler 804 has one copied sheet.
Since there are only two sheets, paper binding is meaningless, so the ejection feeder 0805 is rotated and the paper is sent out without performing phase F434 related to paper binding (phase F435).

When the paper discharge sensor S5 confirms that the copied paper has passed (phase F436), the feeding roller 805
Stop (phase F437).

Thereafter, on condition that the stable limit release switch is off (phase F438) and that there is a 30-page signal (phase F439), the document table 6
It is checked in phase F440 whether there are any remaining documents in 02. Furthermore, if there is a document, the flag for the remaining document signal is turned on in phase F441, and this routine ends.

Returning to FIG. 6, after the stable mode is executed in phase F43, the process advances to phase F44, and if there is no document remaining here, it means that copying of 1 copy (1 set) has been completed, so phase F45 Then, the count value of the copy counter is incremented by "1" and displayed on the "number of copies" display section of the display section 260. Therefore, the copy number display section, which has conventionally been used as a copy number display, is now used as a counter display section for one copy of the original.

Next, in phase F46, the value of the copy counter (
If there is a discrepancy (see Figure 2), a predetermined number of copies are required, so the document release solenoid 5OLI is turned on in phase F47 to stop the document. The group of originals stored on the plate 611 is dropped onto the original table 602, and
Reset the original counter and continue copying again. It should be noted that the display of the document counter, ie, "Returning" display, may not be reset.

If the verification results in phase F46 match (see FIG. 3), all copying schedules have been completed, so the solenoid 5OL4 of the switching pawl 802 is turned off and the pawl position is changed to the position shown in FIG. 12. Return to the position indicated by the solid line in , and end the process.

Note that in the RADF mode, in the case of the doggy tail mode, the process proceeds from phase F39 to phase F52, where it is checked whether or not the original is finished. If the original is not finished, the process moves to the original transport mode (phase F36). ) etc. are repeated. Then, when the original is completed and the original end signal is turned on in phase F52, one set of copies has been made, so doggy tailing is performed and sorted in phase F53. Thereafter, the process is repeated until a predetermined number of copies are completed.

It should be noted that the stapler 804 can perform arbitrary paper binding offline by operating the manual stable switch SW8.

As described above, in this example, when the absence of staples is detected during copying in the stable mode, the next paper discharge mode is automatically set to the doggy tail mode, thereby eliminating lost time.

Furthermore, since the copied sheets discharged to the paper tray are already sorted, they can be bound with a stapler or the like as needed.

Therefore, operability is good.

Furthermore, in this example, when the original is placed on the document table,
Automatically uses R that is frequently used and has high copy productivity.
Since the combination of ADF mode and stable mode is automatically selected (phase F4), operability is improved. Furthermore, when the RADF mode is designated by the switch SWI, generally a doggytail mode that is compatible with the ADF mode is automatically selected (phase F6), so that operability and copy productivity can be improved from these points as well.

Furthermore, - according to the intra-membrane needs, the stable mode is
Selection is prohibited except when the RADF mode is selected, and the doggy tail mode can be selected independently, allowing sorting even in the pressure plate mode.

Note that in the above example, the mode is automatically shifted to the doggy tail mode upon detecting the absence of a needle, but there is no harm in interrupting the copying process.

(Effects) According to the present invention, each copy operation such as the RADF mode can be sequentially displayed on the operation panel, and the copy operation can be accurately and easily known. Therefore, each copy operation can be performed satisfactorily.
