Abstract

PURPOSE:To make it possible to reduce the burden of the operator during selection of mode keys, by applying a preferential order to the time of original setting and the time of selection of RADF/ADF modes to automatically select and indicate staple/ doggy tail modes. CONSTITUTION:When a sensor S1 detects the setting of originals G, an RADF mode is automatically selected for an ADF and a staple mode is automatically selected for a finisher if none of RADF/ADF modes is selected by a first mode selection key. Further, originals from which copy has been made are stacked once by means of an original stopping plate 611 on an original bed 602, and are allowed to stand by until copy is made from all remaining originals which are then fed to the original bed. After completion of copy for all originals, the stopping of the originals may be released, and then one set of originals are dropped onto the original bed 602 and are put in order. Thus, the originals are automatically bound by a stapler 804. Then, during operation of the ADF in the ADF mode, the doggy tail mode is automatically selected for the finisher to expose one and the same original each time for a required number of sheets of copying paper, and then the originals are stacked by means of the original stopping plate 611, alternately, to sort them for every predetermined number of sheets.

Description

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

(Conventional technology) Conventionally, there are copying machines equipped with an ADF and a finisher.

Here, the ADF has a function of sequentially feeding a large number of documents onto a contact glass serving as an exposure section, and for example, two modes are possible for this document feeding mode.

One of these is the circulation automatic feed mode (hereinafter referred to as RADF mode) in which the original is automatically fed in circulation.This mode is convenient for obtaining a predetermined number of copied sheets (hereinafter referred to as copies) one by one in page order. , 1 copy for 1 original
This is performed in combination with a copy process in which a copy cycle corresponding to a copy is repeated a predetermined number of times.

The other is a one-pass automatic feed mode (hereinafter referred to as ADF mode) that automatically feeds the original in a non-circulating manner. In this mode, which is convenient for obtaining sorted documents, documents are intermittently fed one by one to the exposure unit, and after a predetermined number of copy cycles (exposure scans) are performed on the fed documents, , is executed in combination with the copy process of replacing the original with the next one. Also, for the finisher, two modes are possible.

One is the doggytail mode, in which the copied sheets are sorted one copy at a time using a rocking table that swings intermittently. This is a stapling mode in which paper is bound using a paper binding device such as Staple (trade name).

Therefore, in the above example, in a conventional copying machine,
There is a total of four options, two mode selections for the ADF and two mode selections for the finisher, and the operator is forced to make a separate key selection decision for each, which is complicated when used as a system. Ta.

(Objective) Therefore, it is an object of the present invention to provide an improved copying machine that can reduce the operator's complexity regarding the mode key selection.

(Configuration) In order to achieve the above object, the present invention includes a first mode selection key for selecting and specifying each mode in the ADF and a mode selected by the first mode selection key on the operation panel of the copying machine. a first display for selecting and specifying each mode in the finisher; a second mode selection key for selecting and specifying each mode in the finisher;
It has a second display that displays the mode selected by this mode selection key, and even if the copier is turned on without any originals in the ADF, the ADF and finisher can automatically select each of the above modes. To automatically prioritize RADF mode and staple mode and display the selection on a display when the copying machine is turned on and a document is set in the ADF without displaying the display. It is characterized by

The reason for this configuration is that when copying a large number of originals, it is common for users to bind each copy in page order, so the operator does not need to specify any keys. When a document is placed in the ADF, it would be more convenient to automatically set the combination of the staple mode and the compatible RADF mode with priority, and this would reduce the burden on the operator. .

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

In FIG. 8, a contact glass 200 is provided at the center of the upper surface of the main body 2 of the copying machine. An ADF 6 is provided to cover this contact glass 200. Further, a finisher 8 is connected to the left side of the copying machine main body 2.

First, an overview of the configuration and operation of the ADF will be explained.

The ADF 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 for manually setting an original on the document table, and should be compatible with this mode (the ADF 6 should be able to swing toward and away from the contact glass 200 with one end as a fulcrum). It is.

In FIG. 9, details of the ADF are shown enlarged.

Reference numeral 601 indicates a belt, which has the function of sandwiching the original together with the contact glass 200 and conveying the original according to its rotation, and also functions as a reflection plate and a pressure plate. To the right of the belt 601, there are two document trays, upper and lower, for receiving documents. The upper stage is called an original stacking table 602, and the lower stage is called a document table 603.

The paper feeding operation in the RADF mode is as follows.

In the RADF mode, 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. When the document sensor S1 detects that the document G is set, the first mode selection key (switch SW to be described later) is pressed.
1 or switch Sυ3), the RADF mode is automatically selected for the ADF, and the staple mode is automatically selected for the finisher. Then, when the print switch is turned on, the copying process begins. When the paper feed roller 605 rotates clockwise, the bottom original is separated and turned along the guide plate 606.
Paper refeed roller 607 rotates counterclockwise when feeding paper.
The document is guided to the document table 603 by the document table 603 . Therefore, the image plane is facing down.

Then, when the rear end of the 1M document passes the document sensor S2 provided on the document table 603, the rotation of the paper refeeding roller 607 is stopped, and then the reverse rotation is started, and the document is placed on the contact glass 203.
lead to lead. 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 ski scanner 202, which includes the exposure lamp 201 and the first mirror MLI, is normally located at the first home position HPI, which is the left end of the contact glass 200.
However, when this document is sent to the document table 603, it is already in the second position on the right side of the contact glass 200.
It moves to home position 11P2 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 skier 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, which has been exposed, is sent by a belt 601 to a reversing roller 609 and a guide 610, where it is turned and guided onto the original table 602 through the belt. A reversal sensor S3 provided in the guide 610 checks for abnormality in document conveyance. This copied original is placed on the original stop plate 6 which is rotatably provided on the original table 602.
A portion of the document is stacked at 11, and the document waits until all remaining documents are copied and fed here. When the copying is completed, the document stop plate 611 rotates clockwise to release the stoppage of the documents and drop the set of documents onto the document table 602, allowing the next copying process. The above is an outline of the operation of the ADF in the RADF mode.

Next, an outline of the operation of the ADF in the ADF mode will be explained. In the ADF mode, the finisher automatically selects the doggy tail mode. In the RADF mode, as described above, the scanner 202 is stationary at the second home position HP2, and the original is moved and exposed, but in the ADF mode, Before starting the copy operation, the scanner is in the first home position HPI.

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 SPI, which is a predetermined position on the contact glass 200, the scanner 202 starts exposing the document while moving to the right. do. While being exposed to light,
The manuscript is stationary. After the scanner 202 moves to the right to a predetermined distance suitable for the exposure of the original, it turns and returns to the first home position HPI, and repeats exposure scanning for the specified number of copies of the same original. Note that the symbol SP2 indicates the movement end position of the scanner 202.

The exposed document is reversed by a reversing roller 609 and a guide 610, passes over the belt 601, and is stacked on a document stopping plate 611 via a guide plate 606.

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

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

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

The switching pawl 802 is selectively swingable around the axis between the position shown by the solid line and the position shown by the imaginary line. A passage to stapler 804 is formed.

For this finisher, when the staple mode is selected, the copied paper is delivered to the copy outlet 20.
3 into the finisher 8, and the switching claw 802
Since the drive mechanism of is turned on and is at the position of the imaginary line, it is guided toward the stapler 804. Then, when the last sheet passes through the sensor S3 provided just before the stapler 804, it is aligned by a sheet aligning device (not shown), and then the - set of copied sheets is automatically stapled by the stapler 804. Ru. The stack of sheets bound in this way is returned to the conveyance path again by the rotation of the feed roller 805, and is ejected to the paper tray 803 via the ejection sensor S5.

Next, when the doggy tail mode is selected for this finisher, the copied paper is fed into the finisher 8 from the copy ejection port 203, the drive mechanism of the switching claw 802 is turned off, and it is placed in the solid line position. Since the paper is located at the paper tray 803, the paper goes straight and is ejected to the paper tray 803. A.D.
In the F mode, when a predetermined number of copies of the same document are stacked on the paper tray 803, the paper tray 803 changes its position within the paper placement plane. That is, as shown by arrows in FIG. 10, 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 doggytail mode is selected in the RADF mode, the position of the paper tray 803 is switched every time a copy of the original set on the original platen is made, so even if paper binding is not desired, the pages can be arranged in order.

Next is the copying machine main body 2, to which an in-shell electrophotographic copying machine can be applied.゛The outline is as follows.

The light image of the document irradiated by the exposure lamp 202 passes through the first mirror MLI, the second mirror ML2, the third mirror ML3, the fourth mirror 4, the fifth mirror ML5, the sixth mirror ML6, and the lens 204, and then onto the photoreceptor drum. The image is formed on 205.

In the pressure plate mode and the ADF mode, the exposure lamp 201 and the first mirror MLI move to the right by a stroke amount corresponding to the document size to perform exposure scanning. At this time, in order to maintain the optical path length to the lens 204 constant, the second mirror ML2, the third
The mirror ML3 is one of the strokes of the exposure lamp 201, etc.
/2 move.

Around the photoreceptor drum 205, main chargers 206. A developing device 207, a transfer charger 208, a cleaning device 209, and the like are arranged. code 210°21
Reference numeral 1 indicates a paper feed section, in which copy sheets of different sizes are stacked. At the time of paper feeding, copy paper that matches the original size is fed out from paper feed roller 210A or paper feed roller 210B by selecting a paper feed section, and is sent toward photoreceptor drum 205 via registration rollers 212. Then, the toner image is transferred by the transfer charger 208 and sent to the fixing device 218 via the conveyor belt 213, where the image is fixed, and then sent to the finisher 8 from the copy outlet 203. In addition, in the case of double-sided copying, the reversing guide 214 and the double-sided intermediate tray 215
After being reversed, the toner image is transferred to the back side via 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 discharge sensor S7 is provided immediately before the roller 216 provided immediately before the copy discharge port 203. ing.

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 SWI is a mode selection key for specifying the ADF mode, the switch Sυ2 for the doggy tail mode, the switch SW3 for the RADF mode, and the switch SW4 for specifying the stapling mode. The switches swi and SW3 are called first mode selection keys, and the switches SW2 and SW4 are called second mode selection keys. or.

LPI to LP4 provided above each switch are indicators that light up when the switch is turned on to notify that the mode has been designated. The lamp LPI P3 is the first indicator, the lamp LP2. LP4 is called a second display. The switch group SW5 includes, for example, switches for specifying the rate of enlargement, reduction, etc. The switch group SW6 includes switches for specifying the number of copies and the number of copies. switch SW7
is a print switch that instructs the start of the copy process.

Reference numeral 260 indicates a display section, the details of which are shown in FIGS. 12 to 14.

In FIG. 12, the segment "number of copies" display section displays the specified number of copies or copies manually entered by the operator. Further, the number of processed copies or the number of copies that have been processed is sequentially displayed in the "number of copies" display section.

Furthermore, the upper counter display section 261 is, for example, 5×10
It consists of a 40-character display consisting of 1 dot and a CD, and the number of processed manuscripts is displayed on the left side as ``Genko Maisuu''.
The total number of copies is sequentially displayed on the right side as "1-1 total copy".

For example, when three copies of a five-page original are specified and one copy is completed, a display as shown in FIG. 13 is displayed.

In other words, the number of set copies is "3" and the number of processed copies is "
1", and at that time [Genkomaisu J display is "5"
, the "total copy" display is "5". In this case, "r set number of copies" is the number of sets, "number of copies per copy"
shall mean the number of copies.

This is the 14th copy when the specified 3 copies have been copied.
It will be displayed as shown in the figure. That is, the "number of copies" is displayed as "3", and the "total copies" display is the total of "15", which is the number of original sheets (5) x the number of copies (3).

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 unit 270 includes the copying machine main body 2,
It comprehensively controls everything including the ADF 6 and finisher 8. The main control unit 270 is equipped with a microcomputer, and the ADF control unit 271 is in charge of controlling the ADF 6.
, an operation control section 272 in charge of controlling the operation panel 250
, communicates with a scanner control unit 273 that is in charge of controlling the scanner 202, and the like.

These ADF control section 271, operation control section 272, and scanner control section 273 are each equipped with a microcomputer.

The belt 21 is controlled by the ADF control unit 271.

The LCD of the counter display section 261 is controlled by the operation control section 272, and is controlled via the driver 274. Further, the LEDs constituting the lamp LP, various key switch groups SW, etc. are also controlled.

The scanner control unit 273 controls a motor M5, which is a drive source for moving the scanner 202, and a switch 5WIO, which is turned on to stop driving the motor M5 when the scanner 202 reaches the first home position (IPI). , a switch 11 that is turned on when the scanner 202 reaches the second home position ((P2) to stop driving the motor M5.

The main control section 270 controls a load group 274 in addition to the above-mentioned control sections. The load group 274 includes the heat source of the fixing device 218 and the exposure lamp 201. The main controller 270 also receives various signals 275 generated according to the copy process.

In addition, a sensor S8 as a detection means for detecting the presence or absence of staples of the stapler 804, a registration sensor s6, a switch 5I118 for manually binding paper, a staple limit release switch SW9, a staple solenoid SOI for paper binding, 3. A solenoid 5OL4 for driving the switching claw 802, a sensor S4 that detects the arrival of copy paper to the stapler 804, a paper discharge sensor S5 that detects the arrival of copy paper to the paper tray 803, and swings the paper tray 803. The motor A6 for the toggy tail and the like are also involved in the control by the earth control section 270.

Next, follow the flowcharts in FIGS. 1 to 7.

Explain the copy process.

First, in FIG. 1, it is checked in phase Fl whether or not an original is set on the original table 602. If the document sensor S1 detects the presence of a document, the F2 phase is bypassed and the process proceeds to the F3 phase, where the stapler
A check is made at 804 to see if there is a staple for paper binding. If a staple is present, the RADF mode and staple mode are automatically selected, and a lamp LP on the operation panel 250 indicates this. If it is determined in phase F3 that the stapler is out of staples, in phase F16, the stapler out-of-staple status is displayed on the operation panel 250 and other appropriate parts, and a warning to replenish the staples is given. Furthermore, since the stapler 804 cannot perform paper binding due to the lack of staples, phase F17
RADF mode and needle-free doggytail mode are selected, and a message to that effect is displayed on the operation panel 250.

Note that even if the yK stacking table document is not sent 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.

Next, in phase F5, the presence or absence of ADF mode selection is checked. Here, if the ADF mode is designated by the switch SWI, the mode set and display in phase F17 is switched to ADF mode and doggy tail mode and displayed in phase F6. 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 staple mode has been selected. If the staple mode is selected here, the process moves to phase FIO, and it is checked whether or not the RADF mode is selected. If RADF mode is selected, stapler in phase FIL
It is checked if there is no needle, and if there is no needle, then phase F1
After displaying "no needle" at step 8, the process moves to phase F13. If staples are present, the staple mode is displayed and set in phase F12.

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

Phase F13 is a subroutine for checking other inputs, in which the temperature of the fixing device 218 is set, the copy magnification is specified, and the mode is manually specified using each switch on the operation panel 250. For this reason, phase F5. F7. This is why the mode is repeatedly checked using F9° FIO, etc.

When other input checks are completed in phase F13, a state in which copying is possible is waited for 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. 2. If RADF mode or ADF mode is specified, phase F2
0, the document processing mode subroutine is executed.

Here, the subroutine of the "original processing mode" (see FIG. 3) will be explained.

When the print switch Sυ7 is turned on, the
At F201, the motor M3 starts to drive, thereby rotating the paper feed roller 605 and starting to feed the M document on the document table 602 toward the document table 603.

The old motor is turned on when the J7X document sensor S2 detects the document, and then turned off after the paper has been sufficiently fed onto the document table 603.
After the determination is made in step F202, the drive is stopped (phase F203). In this way, when the document ii is sent to the document table 603, if the document sensor s1 is still on, this indicates that there is still a document remaining on the document table 602, and if the document sensor S1 is off, the document It can be seen that there was only one original on the table 602.

If there is only one original, ADF mode is sufficient and RADF mode is not necessary. Also, there is no need to set the staple mode. Furthermore, if the RADF mode and the stapling 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, there is only one document, so in phase F206, the setting and display of RADF mode and staple mode are canceled, and in phase F207, AD
Set to F mode and display it. Note that when the document sensor S1 is on in phase F204, there are at least two documents, so phase F, which is the "scanner 1 (move to P2") subroutine,
Proceed to 2O3 and install scanner 2 for RADF mode.
02 to the second home position l+P2.

Here, the subroutine (FIG. 7) of "move scanner to IF5" will be explained.

Phase F2O3], the motor M for driving the scanner 202
5 is turned on to move the scanner forward, i.e., to the right, and the scanner turns on the switch 5WII. In phase F2053, the motor S5 is turned off and the scanner is positioned at the second home position (P2).

Returning to FIG. 2, 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”, it is the normal pressure plate mode, and the phase F
Immediately after moving to step 26, copy routine 1 is executed.

This copy routine is a well-known copy processing routine that controls the feeding of copy paper from the paper feed unit 2]0 or the paper feed unit 211, controls the device around the photoreceptor drum 20, controls around the scanner 202, etc. be. However, at this time, the scanner 202 uses the first home position HP1 as a reference position and performs exposure scanning by a length determined by the length of the original and the magnification ratio inputted in phase F13.

When "copy routine 1" is executed in phase F26,
Copy counter 1, which counts the number of processed copies, displays “
1" is added to the copy counter 2 that counts the total number of copy processing (phase F27).
), the contents of the copy counter 1 are displayed on the counter display section 2 in the "number of copies" display section in the display section 260 in FIG.
Copy counter 1 is displayed in the "Total copy" display section in 61.
The contents are displayed.

Thereafter, a copy cycle is performed until the content of the copy counter 2 and the number of rcerat sheets match.

If they match, the process ends and the process moves from phase F28 to phase F2.
Move to 9. At this time, if the doggytail mode is designated, a "doggytail movement" subroutine (described later) is executed in phase F30. If the doggy tail 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, if it is the pressure plate mode, all copying ends here, and if it is the 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 a subroutine for document transport mode is executed.

Here, the document transport mode subroutine (see Figure 4)
I will explain about it.

Here, as described above, the first sheet of the original set on the original table 602 has already been set on the original 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, each drive motor for the paper refeed roller 607 is turned on. This results in
The original is sent out from the original table 603 toward the contact glass 200. When the leading edge of the document turns on the document sensor S2, the process advances from phase F233 to phase F234, where "1" is added to the count value of the document counter, and the content is displayed as "Returning" on the counter display section 261 in FIG. displayed in the section.

Thereafter, the process advances to phase F235, where it is checked whether the count value of the document counter is "30".

If the count value of the document counter is "3o" here, the "30 document signal" is turned on in phase F244. This "30 originals signal" is necessary information in the staple mode subroutine (see Figure 5).
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. If 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 document sensor S1 checks whether there is a document on the document table 602, and if there is a document, the drive motor M3 of the paper feed roller 605 is turned on in phase F241, and the drive motor M3 of the paper feed roller 605 is turned on in phase F241 (the third phase). (see figure), feed the original to the original platen 603 (phase F24
2) Turn off motor M3 (phase F243).

If it is determined in phase F240 that there is no document on the document table 602, the process advances to phase F245 and the "document end signal" is turned on.

Returning to FIG. 2, once the document transport mode subroutine of phase F23 is completed, the motor A4 is turned on to drive the paper refeeding roller 607, and the phase starts after a predetermined time after the document sensor S2 is turned on. At F24, the original is set on the contact glass 200.
In phase F25, the phase F2 signal is output.
31 (see FIG. 4) 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 doggy tail mode is selected, the process moves to a "doggy tail movement" subroutine of phase F30, and the paper tray 803 is moved. If it is not the doggy tail mode, copying is repeated until the end of the original through phase F31.

Here, the subroutine (6th
(see figure) will be explained.

If it is in 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 forward rotation flag is not set,
In phase F303, the doggy tail motor M6 is driven in forward rotation for t seconds to move the paper tray 803 from the existing position to the opposite side and set the forward rotation flag. If it is determined in phase F302 that the forward rotation flag is set, the doggy tail motor M6 is driven in reverse for t seconds in phase F304 to move the paper tray 803 from the existing position to the opposite side and reset the forward rotation flag. do.

That is, the paper tray 803 swings left and right by a fixed amount to sort each copy of a predetermined number of sheets.

Returning to Fig. 2, after executing the "doggy tail movement" routine, if in ADF mode, go 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 mote will be explained.

If the RADF mode is designated, in FIG. 2, 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 the document sensor S1, the scanner 202 is moved to the second home position HP2 and becomes stationary in phase F2O3, as described above.

This completes the preparation for the so-called sheet-through mode in which the scanner 202 is held stationary while moving the original for exposure scanning. Here, the scanner 202 was moved to the second home position HP2 near the document table because
In order to speed up the processing time as much as possible, when the document is of a long size, the leading edge of the document passes through the reversing section by the guide 610 at the left end.

This is to prevent the document conveyance speed (scanning speed) from changing.

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 the mode is the staple mode.

If it is not the staple mode, it is the doggy tail mode, and the process eventually moves to phase F53.

In the staple mode, it is checked again in phase F34 whether or not the stapler 804 has no staples. The reason why the needleless check is performed here is because this is the time to start again 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. 8, thereby forming a conveyance path to the stapler 804. After that, the process moves to phase F35.

If it is determined that there is no needle in the above phase F34, in phase F49, the absence of a needle is displayed on the operation panel 250, etc., and the solenoid 5OL4 for the switching claw 802 is turned off, and the switching claw 80
2 in the solid line position, secures the path to the paper tray 803, and automatically enters the doggytail mode (phase F5).
1). Stapler 8 without paper binding because there is no staple
This is because if the paper is sent to 04, a paper jam will occur when the paper is ejected.

If there is a staple, the process moves to phase F35 and executes the "original transport mode" subroutine (see FIG. 4), as described above. Here, regarding refeeding of the original, use the ADF mentioned above.
The operation is similar to the operation in phase F23 in the mode,
After adding "]" to the document counter in phase F234, it is checked in phase F235 whether or not it is the 30th document.

If it is the 30th document, the 30th document signal is turned on in phase F244, and the process moves to phase F236.

Here, since it is the 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 the main flow in FIG.

That is, in the copy routine 1 of phase F26, after the copy paper is fed, the scanner 202 waits at the registration roller 212 shown in FIG. Then, the process is restarted from the registration rollers 2] and 2, and this timing adjustment allows the toner image on the photosensitive drum 205 to be aligned with the copy paper during transfer.

However, in the RADF mode, the scanner 202 is fixed at the second home position HP2, and as in copy routine 1 above, the restart timing of the registration roller 212 is determined based on the start signal generated in conjunction with the movement of the scanner 202. can't get it. Therefore, a signal when the document sensor S2 is turned on is used as a paper restart signal in place of the start signal. This is the reason why the copy routine F37 is provided.

Now, in FIG. 4, 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 at that time, the document sensor S
1 is on, the next original is set on the original table 603 in the same way as in the ADF mode (phases F241, F242, and F243).

When this process is completed, "copy routine 2" is executed in phase F37 of FIG. As mentioned above, this Copy Print 2 is different from the Copy Print 1 only in that the paper restart part is different and that the document is exposed by moving relative to a fixed scanner.Other than that, the copy process in the pressure plate mode/ADF mode is different. In accordance with

When the copy routine 2 is completed in phase F37, the copy counter 2 is incremented by 1 in phase F38, and the value is displayed on the "total copy" display section of the counter display section 261 in FIG.

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

This staple limit release switch is a DIP mill switch as one of the various key switch groups Sυ shown in FIG. If this switch is turned on, it indicates that the stapling limit of 30 sheets, for example, has been lifted, and the "Document 30
The process moves to phase F42 without checking the "sheet signal on", and then repeats the process starting from phase F33 to execute copying until the number of sheets set on the document table 602 is completed. Paper binding is performed for the copies.

Here, the restriction of 30 originals may be lifted as follows:
This is because if the copy paper is thin, it may be possible to bind 30 or more sheets.

If the staple limit release switch is turned off in phase F40, it is assumed that the stapler cannot staple more than 30 sheets of paper.
After copying the first sheet, the copying is temporarily interrupted, and then paper binding is performed, and after that, more than 30 sheets are copied in the same manner and then paper binding is performed.

Normally, regardless of whether the staple limit release switch is turned on or off in phase F40, the document counter remains in phase F4.
Phase F unless you turn on the "30 originals signal" in step 1.
42, copying is performed until the document end signal indicating that there is no document on the document table 602 (however, the copied document is stopped by the document stop plate 611) is turned on by the document sensor S1, and copying is performed in phase F43. Move to "Staple mode".

Here, the subroutine of the "stapling mode" (see FIG. 5) will be explained.

At this stage, copying of one copy of the original has been completed. When the last copied sheet turns on and then turns off the sensor S4 that detects the arrival of the copied sheet to the stapler 804, that is, when the copied sheet passes the sensor S4, the process shifts from phase F431 to phase F432, as shown in FIG. The paper is aligned along with other copied sheets that have already been stored in the paper alignment device that omitted the above, and 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 staple solenoid 5QL3 is turned on to perform paper binding.

Note that if there are 30 or more originals and it is necessary to paper-stitch copies of some (sets) of originals in two or more times, the staple limit release switch is off in phase F40, so the phase Proceed to F41,
Wait for the “30 originals signal” to be turned on and phase F
Shifts to the stapling mode of No. 43.

In this case, if there are 30 originals, phase F43 in Figure 5
3, the original remaining signal is off, so phase F434
If the number of originals exceeds 30, it is determined whether or not to perform paper binding depending on whether the remaining number of sheets is one or two or more. This is because when only one original remains, it is meaningless to paper-bind one sheet of copy paper corresponding to it.

Therefore, in order to make this determination, if there is a remaining document signal in phase F433, the flag for the remaining document signal is turned off in phase F422, and "30" is subtracted from the count value of the document counter in phase F433. Determine whether the value is "1". If the above value is not "1", it means that the stapler 804 has 2 or more copies of 30 sheets or less, so the process advances to phase F434.
Paper binding is performed, and then the ejection feed roller 805 is rotated and sent out (phase F435).

If the value in phase F443 is determined to be "1", there is only one copied sheet in the stapler 804, so paper binding is meaningless, so phase F434 related to paper binding is performed. The paper is sent out by rotating the ejection feed roller 805 without performing the
).

When the paper discharge sensor S5 confirms that the copied paper has passed (phase F4'36), the feeding roller 805 stops (phase F437).

Thereafter, on condition that the staple limit release switch is off (phase F438) and that there is a 30-page signal (phase F439), the document table 600
It is checked in phase F440 whether there are any remaining originals, and if there are any remaining originals, the remaining original signal flag is turned on in phase F441, and this routine is ended.

Returning to FIG. 2, after the stapling 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 one copy (set) has been completed, so the copy count is set in phase F45. Set the count value to “1”
"Number of copies" on the display section 260.
Display on the display.

Therefore, the copy number display section, which has conventionally been used as a copy number display, is used here as a counter display section for one copy of the original.

Next, in phase F46, the value of the above-mentioned copy counter (displayed on the number-of-copies display section) is compared with the number of copies made by Sera 1, and if there is a discrepancy (see Figure 13), a predetermined number of additional copies are required. Then, in phase F47, the document release solenoid 5OLI is turned on, the document stop plate 611 drops the stocked document group onto the document table 602, the document counter is reset, and copying is continued again. It should be noted that the display of the original document counter, ie, the display of the document counter, may not be set.

If the verification results in phase F.16 match (see Fig. 14), all scheduled copies have been completed, so the solenoid 5OL4 of the switching pawl 802 is turned off and the pawl is moved to the 8th position. Return to the position shown by the solid line in the figure and end the process.

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

Incidentally, the stapler 804 can optionally perform paper binding off-line by operating the manual staple switch 5ll18.

In this example, when a document is placed on the document table, it is automatically set to the RA, which is used frequently and has high copy productivity.
Since the combination of DF mode and staple mode is automatically selected (phase F4), operability is improved. Also, R.A.D.
When F mode is specified with switch Sυ3, the staple mode is automatically selected (phase F10), and when ADF mode is specified with switch SWI, the doggy tail mode that generally matches the ADF mode is automatically selected (phase F10).
6) Therefore, from these points as well, it is possible to improve operability and copy productivity.

Additionally, - according to internal needs, the stapling mode is set to R.
Selection is prohibited except when ADF mode is selected, doggy tail mode can be selected independently, and sorting is also possible in pressure plate mode.

(Effects) With the present invention, it is possible to prioritize and automatically select each mode of staple/doggy tail when setting a document or selecting RADF/ADF mode to execute copying, thereby reducing the operator's burden on key selection. This is advantageous because copy productivity can be improved.
