Abstract

PURPOSE:To enable continuance of duplication of the necessary number of sheets, by a method wherein, when choking with a sheet is detected by a sheet refeed device, the sheet refeed device is shifted from a sheet feed mode to a sheet discharge mode, a quantity of sheet equivalent to the number of choked sheets is added for copying. CONSTITUTION:When copying in a double/composite copy mode is effected by the use of a sheet refeed device 130, when the occurrence of choking with a sheet is detected by means of a sensor Se12, a control device automatically resets the number of choked sheets as the number of new copy sheets. An additional copy flag and a copy starting flag are set to 1, and copying motion is continued. Simultaneously, a double/composite copy mode select display LED is brought into an OFF-state during the occurrence of choking with a sheet, the solenoids of switch claws 160 and 165 are respectively brought into an OFF-state, a sheet feed mode is shifted to a sheet discharge mode, and a copy sheet is discharged on a discharge sheet tray 145. This constitution, even when choking with a sheet occurs in the sheet refeed device, enables continuance of copying of the necessary number of sheets without stopping copy motion.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a copying machine, and more particularly, to a copying machine, in which copy paper ejected from the copying machine main body can be once received and then re-fed from the paper feeding section of the copying machine main body. The present invention relates to a copying machine equipped with a paper refeeding device.

In general, in order to perform double-sided copying or composite copying in a copying machine, it is necessary to feed the copy paper again after the first copy has been made, and various paper refeeding devices have been proposed for this purpose. .

For example, JP-A-49-63441, JP-A-56-
Publication No. 95264 states that in order to enable double-sided copying with a simple operation, in a copying machine equipped with a U-turn path type paper path, a cassette installed in the paper ejection section is inserted between the paper ejection section and the paper feed section. When copying to the front side, it can be moved to the paper ejecting section and the tray will pick up the copy paper, and when copying to the back side, it can be moved to the paper feed section and the tray will re-feed the picked up copy paper. A paper refeeding device is disclosed.

Furthermore, Japanese Patent Application Laid-open No. 58-134659 discloses that in a copying machine equipped with a straight path type paper passage, a sheet storage cassette having a sheet storage opening and a sheet feeding opening is used as a sheet ejection section. A paper refeeding device is disclosed that can be attached to and detached from a paper feeding unit by turning the front and back sides upside down.

However, in each of the paper refeeding devices described above, since the cassette itself is moved from the paper ejection section to the paper feed section, it is necessary to provide a separate paper ejection tray in the paper ejection section when back side copying is performed, and each cassette is moved from the paper ejection section to the paper feed section. The problem is that it is designed as a special product, and it is impossible to install it as an option in existing copying machines that do not have a paper refeeding device.

Therefore, the present applicant has already developed a paper refeeding device main body, which is equipped with a paper ejection tray and a paper refeed cassette that can also be attached to and detached from the paper feed section of the copying machine main body, to be attached to the paper ejection section of the copying machine. (Japanese Patent Application No. 61-18501).

By the way, if a paper jam occurs in such a paper refeeding device, you can change the paper feeding mode to paper output tray mode and eject the copy paper onto the paper output tray, which will stop the copying machine from operating. The copy operation can be continued without any interruption.

However, if the operator is given the task of changing the paper feed mode to the output tray mode, the process may not always be done in a timely manner, and furthermore, it is necessary to correct the number of copies by adding the number of jammed sheets to the number of copies. year,
This is complicated and may lead to operational errors.

In order to solve the above problems, the copying machine according to the present invention includes: (a) a copying machine main body; and (b) a sheet refeeding device that is removably attachable to the main body of the copying machine; The paper refeeding device also has a removable paper refeeding cassette in the paper feeding section of the main body, and can be installed in the paper discharging section of the copier main body or the non-sorted paper discharging section of the sorter, and (c) the paper refeeding device. (d) means for detecting a paper jam in the paper refeeding device; The present invention is characterized by comprising a control means for changing the paper feeding mode of the paper feeding device to a paper discharge tray mode, and performing copying by adding the number of jammed paper sheets to a set number of sheets.

In the above configuration, when a paper jam is detected in the refeeding device when copying using the refeeding device, the paper feeding mode of the refeeding device is automatically changed to the output tray mode. is,
In addition, copying is continued by adding the number of jammed sheets to the already set number of copies. This eliminates the need for the operator to reset the operating mode or correct the number of copies each time a paper jam occurs, and prevents operational errors.

After a certain period of time has elapsed since the motor (M6) is activated and the timer is activated when the trailing edge of the copy paper is detected, that is, after the time has elapsed for the copy paper to be completely stored in the re-feeding force sensor (150), the motor is activated. It is designed to stop the operation of (M6). The sensor (Se12) is for detecting paper jams such as copy paper being wrapped around the reversing roller (176).

Further, a mylar plate (159) is installed on the main body (131) adjacent to the reversing roller (176). This mylar plate (159) is used to prevent the trailing edge of the copy paper sent from the reversing roller (176) to the paper refeed cassette <150) from heating and curling upward during double-sided copy mode. be. Incidentally, upward curling of the leading edge of the copy paper due to heat curl can be prevented by rotating the presser roller (134) in the clockwise direction.

Next, the operation of the switching pawls (160), (165) and the on/off control of the solenoids (162), (167) will be explained with reference to FIG.

A binding margin (e) of a specified width can be provided on the right side of the copy paper. If there is no margin in the manuscript, providing a binding margin will make it easier to bind the copies.

In this embodiment, two modes are provided. In the first mode, the image is simply moved by the amount of binding (see (A) in FIG. 10). In this mode, if the protruding portion of the document (d) is not a margin, image loss occurs. In the second mode, in order to eliminate image loss, the reduction rate [(paper length - binding allowance)/paper length is calculated from the width of the copy paper (paper length) and the binding allowance, and the reduction rate is automatically calculated. Determine the copy magnification.

[k, Control procedure, FIGS. 24 to 83 (k-1, Control of copying machine main body) FIG. 24 shows the main routine (CPUI) for controlling the copying machine main body (1).

When the (CPUI) is reset and the program starts, first, in step (Sl), initial settings are made to clear the (RAM), initialize various registers, and put each device into the initial mode. In (S2), an internal timer of the (CPUI) is started.This internal timer determines the time required for one routine of this main routine, and its value is set in advance for the step (Sl).
) is set.

Next, each subroutine shown in steps (S3) to (513) is sequentially called, and when the processing of all subroutines is completed, communication with other PU2) etc. is performed in step (514), and step (515) is performed. After waiting for the internal timer to end, the process returns to step (S2). The time length of one routine is used to count the various timers that appear in each subroutine.

FIG. 25 shows a subroutine for processing using a manual feed tray that can be executed in step (S3) of the main routine.

First, in step (520), it is determined whether the manual feed tray detection switch (SW9) is on-edge or not. If it is on-edge, that is, when the manual feed tray (36) is opened,
In step (521'), the manual copy display LED (2
32) is turned on, and in step (522), display "O" in the copy number display segment (221).Next, in step (523), the binding margin + automatic reduction mode selection display L E D (264) is turned on. If it is turned on, a subroutine for processing the introduction of a binding margin is called at step (524). In other words, "binding margin + automatic reduction mode" is a mode that automatically calculates the reduction rate from the length of the paper and the amount of binding margin, and in the case of manual copying, what size (length) of paper is inserted? Since I don't know, I automatically cancel the binding margin + automatic reduction mode.

Next, in step (525), it is determined whether the book copy mode selection display LED (265) is on, that is, whether the book copy mode is on or not. If it is on, the manual copy size is still unknown. Therefore, I can't scan the book, so I followed step (5).
At step 26), the display LED is turned off, and at step (527), the book A side signal (265) and the book B side signal are reset to "rO", and the book copy mode is automatically canceled.

Next, in step (528), when it is detected that the manual feed tray detection switch (S%J9) is on edge, that is, that the manual feed tray (36) is closed, the manual feed copy display LED (232) is displayed. At the same time, "1" is displayed in the copy number display segment (221) in step (530), and the process returns.

In step 1), it is determined whether the upper cassette is selected. If the upper cassette is selected, step (54)
After confirming that the upper cassette has been pulled out in step 2), if the upper cassette is not selected, proceed to step (543).
After confirming that the lower cassette has been pulled out, proceed to step (54).
4) returns the copy magnification to the original magnification (before automatic reduction), displays the magnification in step (545), and sends the magnification to (CPt12> in step (546). The copy magnification, which was determined by the paper length and binding margin of the selected cassette before the selected cassette is pulled out, is automatically returned to the original magnification because it becomes impossible to calculate when the cassette is pulled out.

Next, when the new insertion of the upper cassette or lower cassette is confirmed in steps <547> and (549), the paper feed slot (20) and (
25) is automatically selected and the upper paper selection display L
E D (250) or bottom feed selection display L E D
(251) is turned on and off. At the same time, step <5
Step 51) calls a subroutine that automatically calculates the reduction magnification (a magnification that does not cause image loss based on the vapor length and binding substitution), and then calls the subroutine that processes the automatic reduction magnification calculation in step (552).
The magnification calculated in step (553) is sent to (CPt12) and displayed.

FIG. 27 shows a subroutine for processing a copy operation that can be executed in step (S5) of the main routine.

First, if the book copy mode selection display LED (265) is on in step (560), that is,
It is determined that book copy mode is selected,
When it is determined that the document detection sensor (Se7) of A D F (80) is on-edge in step <561),
That is, when it is confirmed that the original is inserted into the original tray (82), the display L E D (26
5) is turned off, and in step (563''), the book A side signal and book B side signal are reset to 10'', and the book copy mode is canceled. That is, A D F (80)
If you use , the book scan control has no meaning, so even if book copy mode is selected, it will be automatically canceled.

Next, in step (S64), it is confirmed that the manual tray detection switch (SW9) is on, that is, that manual copying is not selected, and in step (565), it is confirmed that the print key (180) is on-edge. If so, it is determined in step (566) whether A D F (80) is being used. And ADF (80)
If not used, the copy start flag is set to "1" in step (S67), and if it is used, the document detection sensor (Se7) is set to "1" in step (568).

On the other hand, if it is determined in step (564) that the manual paper tray detection switch (SW9) is off and manual copying is selected, then in step (570) the manual paper detection sensor (Se2) is checked for the edge. , execute the steps following step (566). Moreover, if both of the steps (565) and (570) are No,
In step (571) it is determined whether A D F (80) is being used. If the ADF (80) is used, in step (572) it is confirmed that the document is in normal position and the copy number is on-edge, and then in step (573) the copy start flag is set to "1".

If the document normal position signal is not on edge in step (572), it is determined in step (574) whether the document normal position signal is on, and if it is on, step (575) is performed.

After the first copy is completed, the paper is re-loaded into the paper cassette (150).
It is determined whether the stored copy paper is a double-sided copy or a composite copy.

If it is not the second copy, in step (576)
(tao), that is, whether or not the first copy is to be made using the paper refeeding device (130). If it is the first copy, the paper refeed cassette detection sensor (Sel) is activated in step (577).
After confirming that the paper refeeding cassette (150) is installed in the paper refeeding device main body (131) by turning on O), the copy start flag is set to 11'' in step (579). If it is determined in step (576) that it is not the first copy, then in step (578) it is confirmed that the original position signal is on-edge, and in step (579) the copy start flag is set to "rl". Furthermore, if it is determined in step (575) that it is the second copy, in step (580) a paper refeed cassette detection sensor (SelO
) is on, and if it is, the paper refeed cassette (150) has been completely removed from the paper refeed device main body (131) and is set in the paper feed section of the copying machine main body 1). The copy start flag is set to 11'' in step (S79).

FIG. 28 shows a subroutine for processing automatic paper selection executed in step (S6) of the main routine.

First, in step (5140), the document size data detected and sent by the CPU 3 that controls the ADF (80) is temporarily stored in the A register.
In step (5141), it is determined whether or not the binding margin creation + automatic reduction mode selection display LED (264) is on. If it is off, the A register is multiplied by the copy magnification in step (5142), that is, the vertical length and width of the document stored in the A register are multiplied by the magnification. If it is on, this magnification is the copy magnification that was calculated based on the selected paper length and binding substitution.
In step (5143), the original copy magnification [copy magnification ÷
(selected paper length - binding substitution) or (selected paper length)], and then in step (5144) the value is multiplied by the A register.

Next, in step (5145), it is confirmed that the first copy is to be made using the paper refeeding device (130), and in step (5146), the size of the paper refeeding cassette (150) is calculated as described above. It is determined whether the paper size is compatible with the paper size stored in the A register. If the size does not match, the process immediately moves to step (5157), sets the size mismatch plug to I"1", and prepares for a warning; if the size matches, or the re-feeding device ( 130), it is determined in step (5147) whether or not the paper refeed cassette detection sensor (SelO) is on. If it is off, the paper refeeding cassette (150) is connected to the paper refeeding device main body (
It is determined that the paper has been taken out from the paper cassette (131) and set in the paper feed section of the copying machine main body (1), and the size mismatch flag is reset to "O" at step (5148>), and the paper is re-loaded from the paper cassette (131) at step (5149). 150) is set.

On the other hand, in the step (5147), the sensor (SelO)
is on and the paper refeed cassette (150) is inserted into the paper refeed device main body (
131), the paper feed port is selected based on the value of the A register. That is,
If it is determined in step (5150) that the A register is equal to the paper size of the upper paper feed force set, step (5150)
In step 151), the size mismatch flag is reset to 10'', and in step 5152, the upper paper feed port (20) is selected. If it is determined in step (5153) that the A register is equal to the paper size of the sketch paper cassette,
At step (5154), the size nonconformity flag is reset to "rO", and at the same time, at step (5155), the lower paper feed port (25) is selected.

Next, in step (5156), the three-stage paper feed unit (60
) is on or not. If it is off, the three-stage paper feeding unit (60) is not connected, so the size mismatch flag is set to ``1'' in step (5157), and the process returns.

If it is turned on, the three-tier paper feed unit (60) is connected, so if it is determined in step (515g) that the A register is equal to the paper size of the upper tier of the three-tier paper feed unit, then in step (5159) Set the size non-conformance flag to "
0'' and selects the upper stage of the three-stage paper feeding unit in step (5160).

If it is determined in step (5161) that the A register is equal to the paper size in the middle stage of the three-stage paper feed unit, the size mismatch flag is reset to "0." in step (5162), and in step (5163) The middle stage of the paper unit is selected. If it is determined in step (5164) that the A register is equal to the paper size in the lower stage of the three-stage paper feeding unit, the size mismatch flag is reset to "0." in step (5165), and the step (51
66) selects the lower stage of the three-stage paper feeding unit.

FIG. 29 shows a subroutine for processing automatic magnification selection executed in step (S7) of the main routine.

First, step (5170)-e A D F (80
) The vertical dimension of the document size data detected and transmitted by the CPU 3 is stored in the A register, and in step <5171) the horizontal dimension is stored in the B register. Next, in step (5172), it is determined whether or not the binding allowance production acid child automatic reduction mode display LED (264) is on, and if it is off, in step (5173), the vertical dimension of vapor ÷ A register l draft is determined. If 0 display L E D (264) is turned on, that is, if ``binding margin + automatic reduction mode'' is selected, the vapor vertical dimension is stored in step <5174). The value obtained by subtracting the binding margin from the paper is stored in the C register as a simulated paper vertical dimension.In step (5175), the vertical magnification is calculated based on the above data and stored in the A register. The magnification factor taking into account the substitution amount is automatically calculated. Similarly, in step <5176), the horizontal magnification factor is calculated and stored in the B register.

Next, in step (5177) the values of the A register and B register are compared, and in steps (5178) and (5179)
The smaller value is stored in the C register as the copy magnification.

The copy magnification obtained in this way is determined in step (5180).
If it is determined that the power of the copying machine is exceeded (outside the possible magnification range), the magnification incompatibility flag is set to r in step (5181).
Set to l. If it is within the ability, step (5182
) to reset the magnification mismatch flag to "0" and
In step (5183), the optical system (11) is controlled (C

93) are executed in sequence.

FIG. 31 shows a subroutine for processing the magnification up key (201') executed in step (5190).

This magnification up key (201') is normally used to increase the copying magnification, but if you turn on the magnification up key <201) while turning on the Anamocopy mode select key (205), it will increase the copying magnification by 1% of the anamocopy ratio. It is also the binding margin copy mode select key <212)
If you turn on the magnification up key (201) while turning on, the up key will be for every 5 mm of the binding margin.

That is, in step (5200) the magnification up key (201
) is confirmed to be on-edge, step (5201)
It is determined whether the analog copy mode select key (205) is on. If it is on, that is, when you turn on the magnification up key (201) while turning on the analog copy mode select key (205), step (5)
207) adds 1/100 to the Anamo ratio memory.

As a result, in step (5208), the anamo rate memory is 1.
．． If it is determined that the number exceeds 42, step (5209)
Correct the anamorphic rate memory to 1.42 in step (52
13') sets the change flag to 1''.

Further, if it is determined that the binding margin copy mode select key (212) is on in step (S202), that is, the magnification up key (201) is turned on while the binding margin copy mode select key (212) is on. If so, 5 mm is added to the binding margin memory in step (5210).

As a result, the binding margin memory is 15 in step (5211).
If it is determined that the binding margin has been exceeded, step 7 (5212) corrects the binding margin memory to 15 mm, and step (5213)
) to set the change flag to "1".

On the other hand, Anamo copy mode select key (205).

If both the binding margin copy mode select keys (212) are off, the magnification key display L is performed in step <5203).
E D (252) ~ (255) , <259) ~
(262) is turned off.

That is, since the copy magnification in this case is different from the magnification that can be displayed by each magnification key display LED, the magnification key display LED is turned off. Then, in step (5204), the magnification is increased to 1/1.
Add 000. As a result, if the step knob (5205) determines that the magnification exceeds 1.420, step (
5206) to correct the magnification to 1.420.

FIG. 32 shows a subroutine for processing the magnification down key (202), which is executed in step (5191).

This magnification down key (202) is normally used to decrease the copy magnification, but the Anamo copy mode select key
If you turn on the magnification down key (202) while turning on 205), it becomes a down key for every 1% of the anamo rate.
Further, when the magnification down key (202) is turned on while the binding margin copy mode select key (212) is turned on, the down key is set for every 5 mm of the binding margin amount.

That is, in step (5220), the magnification down key (202
) is confirmed to be on-edge, step <5221
), it is determined whether the analog copy mode select key (205) is on. If it is on, that is, when you turn on the magnification down key (202) while turning on the analog copy mode select key (205), step (
5227), 1/100 is subtracted from the Anamo ratio memory. As a result, if it is determined in step (5228) that the anamorphic rate memory has become smaller than 0.64, step (
In step (5229), the anamorphic rate memory is corrected to 0.64, and in step (5233), the change flag is set to rl.

Further, if it is determined in step (5222) that the binding margin copy mode select key (212) is on, that is, while the binding margin copy mode select key (212) is on, the magnification down key (202) is turned on. If so, the binding margin memory is subtracted by 5 mm in step (5230).

As a result, the binding margin memory is 5m in step (5231).
If it is determined that the value is smaller than m, step (523
In step 2), correct the binding margin memory to 5mm, and then in step (52)
33) sets the change flag to "1".

On the other hand, Anamo copy mode select key (205).

If the binding margin copy mode select key (212) is both off, the magnification key display L is displayed in step (5233).
E D (252)~(255), (259)~
(262) is turned off.

That is, since the copying magnification in this case is different from the magnification that can be displayed by the magnification key display LED, the magnification key display LED is turned off. Then, in step (5224), the magnification is set to 1/100.
Subtract 0. As a result, if it is determined in step (5225) that the magnification is smaller than 0.640, the magnification is corrected to 0.640 in step <5226).

First, if it is determined in step (5860) that the sorting mode display LED (271) is turned on, in step (5861) it is determined whether the paper detection sensor (Se16) set in the sorting path (107) is on-edge or not. No, and the over flag indicating that the number of copies exceeds the number of bins in step (5862) is "0".
．． Determine whether or not. If YES in both cases, the bin number of the first sorter (100) is incremented in step (5863). However, since the initial value of the bin number is "1", if the bin number is "1", it will not be incremented.The bin number (101) of the first sorter (100) will be sorted sequentially, and in step (5864) the bin number will be incremented. When it is determined that the bin number of the 1 sorter (100) has become ``last bin number + 1'', it is determined in step (5865) whether or not it is a multiple series sorter.If it is an i series sorter, it is determined in step (5865).

If the bin number is not '1', the bin number is incremented.

Next, in step (586B) it is determined whether or not the set number of sheets of paper has been detected, and if the paper has not been ejected, it is determined in step (5869) that the bin number has exceeded the maximum value [in the case of a multi-layer sorter, the bin number has exceeded the maximum value]. Including the sorter (100a)], the over flag is set to rl in step (5870), and the first sorter (100) is set to non-sort mode in step (5871). Also,
When it is determined that the set number of copies have been ejected in step (586g), the bin number of the second sorter (100a) is returned to "1" in step (5872), and the over flag is set to 10 in step (5873). '', and in step (5874) the bin number of the first sorter (100) is returned to 1''.

On the other hand, if it is determined in step (5860) that the sorting mode display LED (271) is turned off, it is determined in step (5B75) whether or not the grooving mode display LED (272) is turned on. . If it is on, it is checked in step (5876) whether the paper detection sensor (Se16) is off-edge or not.

First, when it is confirmed in step (5890) that the paper discharge detection sensor (Se5) of the copying machine body (1) is on, the sorter motor is turned on in step (5891), and the timer (TQ) is canceled in step (5892). do. Next, when off-edge of the discharge detection sensor (Se5) is confirmed in step (5893), a timer (IQ) is started in step (5894). This timer (TQ) is preset for the time it takes for the paper to be conveyed through the path in the sorter (100) and distributed to each bin (101). Therefore, when the end timing of this timer is confirmed in step (S895), step (5896) is performed.
Turn off the sorter motor.

(CPLI5) is reset and the program starts. First, in step (5900), (RAM
), initialize various registers, and make initial settings to put each device into its initial mode.

Next, in step (5901), the internal timer of (CPU 5) is started. This internal timer determines the time required for one routine of this main routine, and its value is set in advance in step (5900).

Next, the subroutines shown in steps (5901) to (5910) are sequentially filled, and when the processing of all subroutines is completed, other processing such as communication with the (CPUI) is performed in step (5911), and step ( 5912
), wait for the internal timer to end, and then proceed to step (590

935), the paper length detection timer (Is) is started.

Next, when off-edge of the sensor (Sell) is confirmed in step (5936), an auto-shut timer (TU) is set in step (5937), and step (59
In step 38), the paper length detection timer (Is) determines whether the paper length is 210 mm. Since this paper refeed cassette (150) is exclusively for A4 horizontal feeding, it is determined whether the paper ejected from the copying machine main body (1) is A4 horizontal feeding or not based on its length dimension of 210 mm.

If it is not A4 horizontal feed, the switching flag is set to "1" in step (5939). This switching flag is set to rl when it is inappropriate to feed the paper into the paper refeed cassette (150), and instructs to switch the paper passing mode to the paper discharge tray mode.

Next, in step (5940) the autoshaft timer (

Turn off the motor (M6) and step (5942).
), when the end of the auto clear timer (TR) is confirmed, the switching flag is set in step (5943).
Set to .

That is, the auto clear timer (TR) can be set slightly longer than the set time of the paper length detection timer (TS) plus the paper conveyance interval time during continuous copying, and the auto shut timer (TO) can be set for speed copying. When the paper conveyance interval is set slightly longer than the time required. Therefore, when the paper is continuously conveyed during speed copying, the vapor length detection timer (Ts) is started one after another in step (5935), and the motor (M6) is never turned off. When the last sheet of sheet copying or continuous copying passes the sensor (Sell), the auto shaft timer (TU') ends for the first time, and the motor (M6) is turned off in step (5941). In addition, the switching flag is non-standard (other than A4 horizontal feed)
When the copy paper is fed in [step (5938)
], When the auto clear timer (TR) ends [step (5942)], r1 is set, and the subsequent subroutine instructs switching to the paper discharge tray mode.

At step 952), it is determined whether the number of copies is less than or equal to a value (50 sheets) that approaches the storage limit of the re-feed cassette (150), which is 70 sheets. If YES in both cases, it is determined in step (5953) whether or not the manual tray detection switch (SW9) is on. If it is on, that is, if it is determined that the manual feed tray (36) is closed and manual copying is not being performed, then in step (5954) a 0 display is displayed to determine whether the double-sided copy mode display LED (276) is on. If L E D (276) is on, duplex copy mode has already been selected, and the current key (275)
