Abstract

PURPOSE:To prevent the occurrence of unnecessary automatic clear motion during double/composite copy mode, by a method wherein, when mounting of a refeed sheet cassette to the copying machine main body sheet feed part is detected, automatic clear function of returning a control system to an initial mode is prevented from working. CONSTITUTION:When mounting of a refeed sheet cassette 150 to the sheet feed port of a copying machine main body is detected by means of an OFF signal from a detecting sensor Se10, a control circuit completes subroutine of initial processing without deciding completion of an automatic clear timer, already started, i.e. without restoring a control system to an initial mode. The control enables continuance of copying by means of a previous copying mode without acting automatic clear function even if it takes a time to mount and dismount the refeed sheet cassette 150 when first copying by means of a double/ composite copy mode is completed and second copying is effected. This constitution enables elimination of a man hour for control by means of an operator without unnecessarily acting automatic clear function.

Description

[Detailed Description of the Invention] Starai Kamibe Tsukiko! The present invention relates to a copying machine, and particularly to a copying machine equipped with a paper refeeding device that allows copy paper that has been ejected from the copying machine main body to be re-fed from a paper feeding section of the copying machine main body after it has been received.

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 is moved to the paper ejecting section and the copy paper is picked up once, and when copying to the back side, it is moved to the paper feed section and the receiver re-feeds the picked up copy paper. The paper refeeding device has been opened completely.

Furthermore, Japanese Patent Application Laid-Open No. 58-134659 discloses that in a copying machine equipped with a straight bus-type paper passage, a sheet storage cassette having a sheet storage opening and a sheet feeding opening is connected to a sheet ejection section and a sheet feeding section. A paper refeeding device is disclosed that can be attached to and detached from a paper portion by flipping it 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 applicant has proposed that the main body of the paper refeeding device, which is already provided with a paper ejection tray and a paper refeed cassette that can be attached and detached to the paper feeding part of the copying machine main body, be attached to the paper ejection part of the copying machine. proposed a paper refeeding device (Japanese Patent Application No. 18501/1983).

By the way, in this paper refeeding device, the state in which the paper refeeding cassette is attached to the paper feeding section of the main body of the copying machine means a state in which a second copy in the duplex/composite copy mode is to be performed. On the other hand, the copying machine itself usually has an auto-clear function that returns the control system to the initial mode after a certain period of time has passed after copying is completed. Therefore, when the above-mentioned paper refeeding device is attached to such a copying machine, even if copying continues in the original operation mode, if there is a delay in attaching or removing the paper refeed cassette, the auto clear function will activate during that time. There is a risk that the

In order to solve the problem beyond the means for solving the problem, the copying machine according to the present invention includes: (a) a copying machine body equipped with an auto-clear function that returns the control system to the initial mode; It has a paper refeeding cassette that is removable from the paper feeding device main body and also removable from the paper feeding port of the copying machine main body, and a refeeding cassette that can be installed in the paper ejection part of the copying machine main body or the non-sort paper ejection part of the sorter. a paper feeding device; (c) means for detecting that the paper refeeding cassette is installed in a paper feeding section of a copying machine main body;
(d) A control means for disabling the auto clear function when it is detected that the paper refeeding cassette is installed in the paper feeding section of the main body of the copying machine. do.

Effects In the above configuration, when the paper refeed cassette is attached to the paper feed section of the copying machine main body and a second copy is to be made in the double-sided copy mode or composite copy mode, the auto clear function does not operate. In this way, the operating mode of the control system is maintained as before, and the operator does not have to reset the operating mode one by one.

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

Further, a mylar board (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 the double-sided copy mode. be. Incidentally, upward curling of the leading edge of the copy paper due to heat curling is prevented by rotating the presser roller (134) in the clockwise direction.

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

[H. Special copy mode, Figures 10 to 12] In the above configuration, the copying machine main body (1) operates in addition to the normal copy mode, the double-sided copy mode, composite copy mode, and other special copy modes. It is possible to copy in binding margin copy mode, analogue copy mode, and book copy mode.

(h-1, lI margin copy mode) In the binding margin copy mode, as shown in Figure 10,
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 yX 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 binding margin (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 margin)/paper length is calculated from the width of the copy paper (paper length) and the binding margin, and the Determine the copy magnification.

(h-2, Anamo copy mode) In Anamo copy mode, as shown in Figure 11,
By keeping the copy width direction (depending on the lens position) the same and changing only the scanning speed of the optical system (11),
Control is performed to shorten or lengthen the copied image in the scanning direction (b). In addition, the analog magnification (aspect ratio) is 95
If it is not within the range of ~105%, the resolution will drop, so if a biased magnification outside that range is specified, a warning will be given to the operator on the display section (220') described below.

In order to obtain stable copies at any analog polarization magnification, a special lens must be inserted into the exposure optical path.

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

Next, each subroutine shown in steps (S3> to (513)) is sequentially called, and when the processing of all subroutines is completed, communication with other (CPU2) etc. is performed in step (514), and step (515) After waiting for the internal timer to end, the process returns to step (S2).The length of time 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 feed copy display LED (23
2), 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
It is determined whether E D (264) is on or not, and if it is 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, it is not known what size (length) of paper can be inserted. Therefore, the binder's automatic reduction mode is automatically canceled.

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 10'', and the book copy mode is automatically canceled.

Next, in step (528), when it is detected that the manual feed tray detection switch (SW9) is on, that is, the manual feed tray (36) is closed, the manual feed copy display LED (232) is turned off. At the same time, in step (530), “

FIG. 26 shows a subroutine for cassette insertion processing executed in step (S4) of the main routine.

First, in step (540) the display L E D (264
) is on, that is, “binding margin + automatic reduction mode”
is selected, step (54
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), check if the upper cassette is not selected (if so, proceed to step 543).
) to confirm that the lower cassette is removed, then proceed to step (5).
44) returns the copy magnification to the original magnification (before automatic reduction), and in step (545) displays that magnification.
In step (546), the magnification is transmitted to (CPU2). This is because the copy magnification, which was determined by the paper length and binding margin of the selected cassette before it was pulled out, becomes impossible to calculate after the cassette is pulled out, so it automatically returns to the original magnification. .

Next, when the new insertion of the upper 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 paper length and binding position), and then calls the subroutine that processes the automatic reduction magnification calculation in step (552).
Send the magnification calculated in step (CPU2) and proceed to step (
553) to display the magnification.

FIG. 27 shows a subroutine for processing a copy operation 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,
If it is determined in step (561) that the document detection sensor (Se7) of the ADF (80) is on-edge, that is, if it is confirmed that the document has been inserted into the document tray (82), then in step (562) The display L E D (2
65) is turned off, and in step (563), the book A side signal and the book B side signal are reset to "0", and the book copy mode is canceled. That is, A D F (80)
If you use , the book scan control becomes meaningless, so even if the book copy mode is fully 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 or not the A D F (80) is used up. And ADF (80)
If it is not used up, the copy start flag is set to "1" in step (567), and if it is used up, the document detection sensor (Se7) is set in step (568).
) is on, that is, a document is placed on the document tray (82), and then proceed to step (569).
) to set the ADF start signal to 11.

On the other hand, if it is determined in step (564) that the manual paper tray detection switch (Sν9) is off and manual copying is selected, then in step (570) it is confirmed that the manual paper detection sensor (Se2) is on-edge. The steps following step (566) are executed. Further, if NO in both steps (565) and (570),
In step (571), it is determined whether A D F (80) is being used. If the ADF (80) is fully used, the on-edge of the original position signal is confirmed in step (572), and the copy start flag is set to rl in step (573).

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) it is checked whether it is the first copy using the paper refeeding device (130), that is, the first copy from now on using the paper refeeding device (130). Determine whether or not to do so. If it is the first paper feed cassette detection sensor (Sel) in step (S77),
After confirming that the paper refeeding cassette (150) is fully installed in the paper refeeding device main body (131) by turning on O), the copy start flag is set to "1" in step (579). Further, if it is determined in step (576) that it is not the first copy, in step (57B>), the on-edge of the original position signal is confirmed, and in step (579), the copy start flag is set to "1."Furthermore, If it is determined in the step (575) that it is the second copy, the paper refeed cassette detection sensor (SelO
) is on or not, and if it is off, the paper refeeding cassette (150) has been taken out from the paper refeeding device main body (131) and has been fully set in the paper feeding section of the copying machine main body (1). Then, in step <579), the copy start flag is set to "rl".

Next, in step <581), the copy start flag is set to "1".
If it is the first copy using the paper refeeding device (130), then in step <582), if it is the first copy, then step (583) )

) to determine whether the number of copies is 50 or less.

If the paper size is inappropriate or the number of copies is 50 or more, the copy start flag is reset to "0" in step (S85).

In other words, if the paper size cannot be accommodated in the re-feed cassette (150), or if the number of multi-copy sheets cannot be accommodated in the re-feed cassette (150),
150), the copying start flag is reset to "r□" and the copying operation is canceled.

Next, in step (586), the copy start flag is set to ``rl''.

Next, in step (sllo), it is determined whether the return signal of the optical system (11) is 11'', and if it is '1'', the paper detection sensor (Se2) of the manual paper feed section is turned on in step (sill). Determine whether or not. Sensor (Se2)
If pi is on, it is determined that the next paper is already set on the manual feed tray (36), and step (5) is performed.
112), a pseudo on-edge of the sensor (Se2) is created and the next manual copy is executed.

If it is determined in the step (stll) that the sensor (Se2) is not turned on, it is determined in step (5113) whether the multi-copy has been completed, and if it has not been completed, it is determined in step (5114). Set the copy start flag to rl. When the multi-copy is completed, step (5115) determines whether the paper jam detection sensor (Se12) in the re-feed cassette (<150) is on, that is, whether a paper jam has occurred in the re-feed cassette (150). 0 If a paper jam has occurred, step (511)

On the other hand, if the paper jam does not occur, step (5115)
If the determination is NO, it is determined in step (5118) whether the additional copy flag is "11" or not. If it is "1", in this embodiment, the additional copy for correction in case of paper jam is 1.
The flag is reset to "rO" in step (5119), and the number of copies is returned to the original number of copies in step (5120).

Next, in step (5121) it is determined whether the book copy mode selection display LED (265) is on, and if it is on, in step (5122) it is determined whether the B side copy signal is "1" or not. That is, the first book copy 8

First, in step (5140), the 0th order temporarily stores in the A register the document size data that has been detected and left by the CPU 3 that controls the ADF (80).
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 and horizontal widths of the document completely stored in the A register are multiplied by the magnification. If it is on, this magnification is the copy magnification calculated based on the paper length and binding margin that were selected at that time.
In step (5143), the original copy magnification [copy magnification ÷
After returning to (selected paper length - binding margin) or (selected paper length), the A register is multiplied by the (7) value in step (5144).

Next, in step (5145), it is confirmed that the first copy is to be made using the paper refeeding device (130), and in step (S146), the size of the paper refeeding cassette (150) is calculated as described above. It is determined whether the vapor size matches the vapor size stored in the A register. If the size does not match, the process immediately moves to step (5157), sets the size non-conformity flag to "1", and prepares for a warning. ), it is determined in step (5147) whether the paper refeed cassette detection sensor (SelO) is on or not. If it is off, the paper refeed cassette ( 150) is the paper refeeding device main body (

At step (5154), the size mismatch flag is reset to "0", 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 11'' in step (5157), and the process returns.

If it is turned on, the three-stage paper feed unit 0) is connected, so if it is determined in step (5158) that the A register is equal to the paper size in the upper stage of the three-stage paper feed unit, the size is set in step (5159). Set the non-conformity flag to r
At the same time, in step (5160), the upper stage of the three-stage paper feeding unit is selected.

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 feed 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.

Store. Next, in step (5172), it is determined whether or not the binding margin creator automatic reduction mode display LED (264) is on, and if it is off, in step (5173), the paper vertical dimension ÷ A register (original length If 0 display L E D (264) is on, that is, if ``binding margin + automatic reduction mode'' is selected, the value of paper vertical dimension is stored in step (5174). The value obtained by subtracting the binding substitution is stored in the D 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.

As a result, the magnification factor can be automatically calculated taking binding substitution into consideration. Similarly, in step (5176), the horizontal magnification 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).

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 the Anamorph mode select key (201)
If you turn on the magnification up key (201) while turning on the key (205), the up key will be in 1% increments of the Anamo ratio, and if you turn on the binding margin Fuppy mode select key (212) and turn on the magnification up key ( 201) is turned on, it becomes an up key for binding substitution every 5 mm.

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 (
5207) adds 1/100 to the anamorphic rate memory.

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

This magnification down key (202) is normally used to decrease the copy magnification, but the Anamo copy mode select key (202)
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.
In addition, when the magnification down key (202) is turned on while the binding margin FP mode select key (212) is turned on, the down key is set for every 5 mm of the binding margin.

That is, in step (5220), the magnification down key (202
) on-edge is confirmed, 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 (522B) that the anamorphic rate memory is smaller than 0.64, step (522B)
In step (5229'), the anamorphic ratio memory is corrected to 0.64, and in step (5233), the change flag is set to "1".

Further, if it is determined in step (S222) 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 rl.

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 copy magnification in this case is different from the magnification displayed by the magnification key display LED, the magnification key display LED is turned off. Then, in step (S224), 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).

18) turns on the display LED (271). That is, each time the key (270) is turned on, the sorter operation mode is sequentially switched among sorting mode, grouping mode, and non-sorting mode.

On the other hand, in step (5819), the paper refeed cassette detection sensor (SelO) is on-edge, that is, the paper refeed cassette (
150) is set in the paper refeeding device (130), the sorter process 1 subroutine is called in step <5820). Also, step (5821
) detects the offset of the sensor (SelO), that is, that the refeeding cassette (150) is removed from the refeeding device (130), calls the sorter processing 2 subroutine in step (5822). .

If it is determined in step (5823) that the sensor (SelO) is on, it is determined in step (5824) whether the double-sided copy mode selection display LED (276) is on or not, and in step (5825) composite copying is performed. It is determined whether the mode select display LED (278) is on. If either one is on, that is, one of the copy modes is selected, the subroutine of sorter processing 1 is called in step (5826). Similarly, in steps (5827) and (5828) the display L E D
<276), if (27B) is on, step (
5829), the subroutine of sorter processing 2 is deactivated.

Next, in step (5830), the paper refeed cassette (150)

First, in step (5840), the selected sorter operation mode is stored in memo 1 (A), and in step (5841
) to determine whether it is a multiple sorter or not. If it is not a 0-multiplex sorter, the non-sort mode is displayed in step (5842).
E D (273) is turned on, and in step (5843), sorting mode display L E D (271) is turned off, and grouping mode display L E D (2
72) is turned off, and in step (5844) the first sorter (
100) is set to non-sort mode. That is, the setting is made so that the first copied paper is sent to the paper refeeding device (130) set in the non-sort paper discharge section of the sorter (100). In addition, if it is a multiple sorter, step (5)

FIG. 71 shows the subroutine of sorter processing 2 executed in steps (5822) and (5829).

First, in step (5850), display the non-sort mode L.
Turn on E D (273) and step (5851)
If it is determined that the mode stored in the memory (A) is the sorting mode, the display L E D <271) is turned on in step (5852), and the display is turned on in step (5852).
5853), the first bin is first selected as the bin (101) to which paper is to be distributed. Step (5854
), if it is determined that the mode stored in the memory (A) is the grooving mode, step (5855)
Then turn on the display L E D <272) and execute step (5853) in the same way. If the mode stored in memory (A) is non-sort mode, step (5)

In step (5857), the first sorter (100) is set to the non-sort paper discharge mode as in step (5835).

Figure 72 shows the main routine steps (of CPU4).
5802) shows a sort processing subroutine executed in step 5802).

First, when 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 sort 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 rg.
, 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 "al", if the bin number is "1", it is not incremented.It is sorted sequentially into the bin (101) of the first sorter (100), and the first When it is determined that the bin number of the sorter (100) has become "last bin number + 1", it is determined in step (5865) whether or not it is a multiple continuous sorter.If it is a 0-multiplex sorter, step (
5866) and set the bin number of the first sorter (100) to '1''.
, and in step (5867) the second sorter (100a
) is not "1", the bin number is incremented.

Next, in step (5868) it is determined whether or not the set number of sheets of paper has been detected, and if the paper has not been completely 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 "1" in step (5870), and the first sorter (100) is set to non-sort mode in step (5871). Also,
If it is determined that the set number of copies have been ejected in step (5868), the bin number of the second sorter (100a) is returned to 11" in step (5872), and the over flag is set to rO" in step (5873). and returns the bin number of the first sorter (Zoo) to "1" in step (5874).

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 (5875) whether or not the grouping mode display LED (272) is turned on. . If it is on, in step (5876) it is determined whether the paper detection sensor (Se16) is off-edge or not, in step (587).
7), check whether the over flag is "0" or not in step (58).
In step 78), it is determined whether or not the set number of sheets have been discharged. If YES in both cases, in step (5879), if the first sorter bin number is not "1", the bin number is incremented. Subsequently, in step (5880), it is determined that it is a multiple sorter, and in step (5881), the bin number of the first sorter (100) is determined to be 'last bin number + 1'.
If it is determined that the first
The bin number of the sorter (100) is returned to 41'', and the bin number of the second sorter (100a) is changed to 1 in step (5883).
” otherwise increment the bin number.

Next, in step (5884), if the bin number exceeds the maximum value [in the case of a multiple sorter, the second sorter (100a
) is determined, the over flag is set to "1" in step (5885), and step (5886
) puts the first sorter (Zoo) into non-sort mode and returns the bin number of the second sorter (100a) to "1".

Furthermore, if it is determined in step (5875) that the grouping mode display LED (272) is turned off, non-sort mode is selected in step (5887).

Figure 73 shows the main routine steps (of CPU4).
5804> shows a subroutine for sorter motor processing executed in step 5804>.

First, in step (5890), when it is confirmed that the paper discharge detection sensor (Se5) of the copying machine main body (1) is on-edge,
The sorter motor is turned on in step (5891), and the timer (IQ) is canceled in step (5892). Next, in step (5893), the discharge detection sensor (Sea)
When the off-edge is confirmed, a timer (TQ) is started in step (5894). This timer (TQ)
The time required for the paper to be conveyed through the path in the sorter (100) and distributed to each bin (101) is preset. Therefore, if the end timing of this timer is confirmed in step (5895), step <5896
) to turn off the sorter motor.

(k-5, control of paper refeeding device) Fig. 74 shows the control of the paper refeeding device (130) (CPU5
) shows the main routine.

When the (CPU) is reset and the program starts, first, at step (5900), the (RAM)
clear, initialize various registers, and make initial settings to put each device into its initial mode.

Next, in step (5901), the internal timer of (CPUS) 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, each subroutine shown in steps (5901) to (5910) is sequentially called, and when the processing of all subroutines is completed, other processing such as communication with (CPUI) is performed in step (5911), and step ( 5912
), wait for the internal timer to end, and then proceed to step (590
Return to 1). This long time of one routine is used to count the various timers that appear in each subroutine.

Figure 75 shows the steps of the main routine of (CPUS) (
The subroutine of the power-on process executed in step S02) is shown.

First, when it is confirmed in step (5920) that the 1L source is on, the double-sided copy mode display LED (276) and composite copy mode display LED (278) are turned off in steps (5921) and (5922), and then in step (5923)
, (5924) and solenoid (162), (167
) off. That is, when the power is turned on, a mode is first set in which the paper is discharged onto the paper discharge tray (145).

Figure 76 shows the main routine steps (
5903) shows a motor control subroutine executed in step 5903).

First, in step (5930) the display L E D (27
6), if it is determined that either of (278) is on, the detection sensor (Sell) is activated in step (5931).
After confirming that the paper is on-edge, that is, when the paper begins to be conveyed into the paper refeed cassette (150) in the duplex/composite copy mode, the motor (M6) is turned on in step (5932). Next, the sheet number counter is incremented in step (5933), the auto clear timer (IR) is reset in step (5934), and step (593) is performed.
Step 5) starts the paper length detection timer (TS).

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

If it is not A4 horizontal feed, the switching flag is set to 11'' in step (5939). This switching flag is set to 11'' 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 auto-shut timer (
When the completion of IU) is confirmed, the motor (M6) is turned off in step (5941), and the motor (M6) is turned off in step (5942).
When the end of the auto clear timer (TR) is confirmed,
In step (5943), the switching plug is set to rl.

That is, the auto clear timer (TR) can be set slightly longer than the set time of the paper length detection timer (1'5) plus the paper conveyance interval time during continuous copying,
The auto-shut timer <TO) is set slightly longer than the paper conveyance interval time during continuous copying. Therefore, when paper is continuously conveyed during continuous copying, the paper length detection timer (TS) starts one after another in step (5935), and the motor (M6) is never turned off. When one copy or the last copy of continuous copying passes the sensor (Sell), the auto-shut timer (TO) ends and the motor (M6) is turned off in step (5941). Also, the switching flag is activated when copy paper of a non-standard size (other than A4 horizontal feed) is fed [step (5938)]
, When the auto clear timer (TR') ends, [step (5942) 1, rl] is set, and the subsequent subroutine instructs switching to the paper discharge tray mode.

First, in step (5950) press the double-sided copy select key.
When the on-edge of (275) is confirmed, step (5)
Step 951) determines whether the selected paper size is suitable (whether A4 horizontal feeding or not), and then proceeds to step (5
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 (S954) the 0 display L is used to judge whether the double-sided copy mode display LED (276) is on or not. If E D (276) is on, duplex copy mode has already been selected, and the current key (275)
Since turning on is the second key operation, processing is performed to cancel the double-sided copy mode.

That is, in step (5955) the display L E D (27

After confirming that the sheet number counter is "0" in step 65), that is, if no paper has been fed into the paper refeed cassette (150) yet, display L in step (5966).
Turn on E D (276) and step (5967)
Turn off the display L E D (27B) and step (5
96B), turn on the solenoid (162), and step (
5969) to turn off the solenoid (167) and switch to double-sided copy mode.

Further, the routine after step (5970) is for selecting the composite copy mode, and step (5970)
When the on-edge of the composite copy select key (93) is confirmed, steps (5971) and (5972) are performed.

0 display L to determine whether D (278) is on or not
If D (27B) is already on, since this is the second key operation, turn off the display LED (278) in step (5975) to cancel the composite copy mode.
In step (S976) and (597B), the solenoid (
162) and (167) are turned off. Said step (5

The refeeding cassette (150) is connected to the refeeding device main body (131)
This shows the subroutine when extracted from.

First, when the off-edge of the paper refeed cassette detection sensor (SelO) is confirmed in step (51000), that is,
When it is confirmed that the paper refeeding force cera) (150) has been pulled out from the main body (131), the sheet number counter is reset to "O" in step (Stool), and the sheet number counter is reset to "O" in step (510).
02), if the display LED (276), (27g) is blinking, the blinking is stopped. At the same time, in step (51003), the over flag is set to 10'', and in step (51004), the paper jam flag is set to 04, and step (

[Margin below] [Main parts of the embodiment] In the above embodiment, the detection sensor (SelO) detects that the paper refeed cassette (150) is installed in the paper feed slot of the copying machine main body (1). When an off signal is detected, [Step (5557) - 1' NO, refer to Figure 53], without determining whether the auto clear timer that has already started has ended [Step (5578), the initial processing subroutine is executed. finish.

With the above control, when the first copy in duplex/composite copy mode is completed and the second copy is made, the auto clear function is activated even if it takes time to attach and detach the paper refeed cassette (150). You can continue copying in the previous copy mode.

Optical BJI (7υ1)As is clear from the above description, the present invention provides a copying machine main body equipped with an auto-clear function that returns the control system to the initial mode, and a paper refeeding device that is removable from the main body. A paper refeeding device having a removable paper refeeding cassette also attached to the paper feeding section of the copying machine main body and installed in the paper discharging section of the copying machine main body or the non-sorted paper discharging section of a sorter; means for detecting that a cassette is installed in the paper feed section of the copying machine main body, and the auto clear function when it is detected that the paper refeed cassette is installed in the paper feed section of the copy machine main body; Since the auto clear function is equipped with a control means that prevents it from operating, the auto clear function does not operate unnecessarily when making a second copy in double-sided copy mode or composite copy mode, etc., reducing the operator's operational effort. This can be omitted and the usability is improved.
