This constitution prevents the occurrence of a trouble, in which copying is started in a state in that the refeed sheet cassette is mounted to the sheet feed part of the copying machine main body, enables elimination of a trouble in that an operator confirms the mounting place of the refeed sheet cassette each time, and improves facility.

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 the copy paper that has been ejected from the copying machine body can be re-fed from the paper feeding section of the copying machine body after it has been received. The present invention relates to a copying machine equipped with a paper refeeding device.

Advanced technology and its problems 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. There is.

For example, JP-A-49-63441, JP-A-56-
Publication No. 952.64 states that in order to make double-sided copying possible with a simple operation, in a copying machine equipped with a U-turn path type paper path, a cassette that is fully installed in the paper ejection section is connected to the paper ejection section and the paper feeder. It can be moved between copies, and when copying to the front side, it is moved to the paper ejection 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 copy paper that was picked up. A paper refeeding device having a similar structure is disclosed.

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 that can be attached and detached by flipping the front and back sides of the paper section has been disclosed.

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 cannot be installed 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, in this paper refeeding device, the normal position is when the paper refeeding cassette is completely installed in the main body of the paper refeeding device, but if it is left in the paper feeding section of the copying machine body, may occur. In such a case, there is a possibility that a problem will occur when starting the next copy, and the operator has to troublesomely check the installation location of the paper refeed cassette each time when starting copying.

In order to solve the above problems, the copying machine according to the present invention includes: (a) a copying machine main body; (C) a paper refeeding device having a removable paper refeeding cassette that is also attached to the paper feeding section of the main body and can be installed in the paper discharging section of the copying machine main body or the non-sorting paper discharging section of the sorter; and (C) the paper refeeding cassette. means for detecting that the is attached to the paper feed section of the copying machine main body;
(d) A control means that warns when it is detected that the paper refeed cassette is installed in the paper feed section of the copying machine main body when power is turned on to the copying machine main body or an all reset signal is input. It is characterized by

Effects In the above configuration, when the copying machine main body is powered on or an all-reset is applied, a warning to that effect is issued if the paper refeed cassette is attached to the paper feeding section of the copying machine main body. This eliminates the problem of starting copying with the paper refeed cassette installed in the copying machine main body, and eliminates the need for the operator to check the mounting location of the paper refeed cassette each time.

all) detects the copy paper that has been completely ejected into the paper refeeding device (130) in any paper feeding mode, operates a counter to count the number of ejected paper sheets, and detects the leading edge of the copy paper. 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 refeeding force (<150), the motor (M6) 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 the double-sided copy mode. It is. 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 pawls (160), (165) and the on/off control of the solenoids (162), (167) will be explained with reference to FIG.

Shows the main routine.

When (CPtJl) is reset and the program starts, first, in step (Sl), initial settings are made to clear (RAM), initialize various registers, and put each device into the initial mode. In (S2), an internal timer of (CPU1) 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 the manual feed tray, which is executed in step knob (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 (23
2) is turned on, and in step <522), display "0" in the copy number display segment (221).0 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 binding and shallow grooving 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 also set. Since I don't know what to do, I can't do a book scan, so I followed step (5)
26'), the display LED is turned off, and in step (527), the book A side device (265) sets the book B side signal to "0.
to automatically cancel book copy mode.

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), “

In step 41), it is determined whether the upper cassette has been selected. If the upper cassette has been selected, proceed to step (5).
After confirming that the upper cassette has been pulled out in step 42), check if the upper cassette is not selected (if so, proceed to step 54).
After confirming that the lower cassette is removed in step 3), proceed to step (
544) to change the copy magnification to the original magnification (before automatic reduction)
, display the magnification using the Ste knob (545), and transmit the magnification to (CPU 2) at step (546). This is because the copy magnification, which was determined by the paper length and binding margin of the selected cassette before the selected cassette was pulled out, becomes impossible to calculate when the cassette is pulled out, so it automatically returns to the original magnification. It is.

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 lower paper feed selection display LED (2
51) on and off. At the same time, step (551)
calls a subroutine that automatically calculates the reduction magnification (a magnification that does not cause image loss based on the paper length and binding substitution), and sends the calculated magnification to (CPU 2) in step (552). and step (553
) to display the magnification.

65) is turned off, and in step (563), the book A side signal and the book B side signal are reset to r□, and the book copy mode is canceled. That is, if ADF<80) is used, the book scan control becomes meaningless, so even if the book copy mode is fully selected, it is automatically canceled.

Next, in step (564), it is confirmed that the manual tray detection switch (SW9) is on, that is, that manual copying is not selected, and in step (S65), it is confirmed that the print key (180) is on-edge. If determined, it is determined in step (566) whether the ADF (80) is fully used. If the ADF (80) is not fully used, the copy start flag is set to rl in step (567), and if it is to be used, the document detection sensor (Se7) is turned on in step (568). After confirming that the document is placed on the document tray (82), the ADF start signal is set to "1" in step (569).

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 fully 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. Moreover, if both of the steps (565) and (570) are No,
In step (571), it is determined whether the ADF (80) is being used. If the ADF (80) is used, in step (572) it is confirmed that the original position signal is on-edge, and in step (573) the copy start flag is set to "1".

If the original position signal is not on edge in step (572), it is determined in step (S74) whether or not the original position signal is on, and if it is on, step (575) is performed.

If it is not the second copy, in step (576) it is determined 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 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 "1" in step (579). If it is determined in step (576) that it is not the first copy, then in step (S78) it is confirmed that the original position signal is on-edge, and in step (579) the copy start flag is set to "1". If it is determined in step <575) that it is the second copy, the refeed cassette detection sensor (SelO) is activated in step (580).

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

First, in step (5140), the ADF (80) is controlled (CPU 3), and the document size data that has been detected and sent is temporarily stored in the A register.Next, in step (5141), binding margin is created + automatic reduction. It is determined whether the mode select 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's on,
This magnification is the copy magnification calculated from the paper length selected at that time and the binding margin, so in step (5143) the original copy magnification [copy magnification ÷ (selected paper length - binding margin) or (selected paper length), then step (5)
144), the value is multiplied by the A register.

Next, in step (5145), it is confirmed that the first copy is to be made using refeeding device e (130), and in step (5146), the size of the refeeding cassette (150) is adjusted as described above. It is determined whether the paper size matches the calculated paper 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 11'', and prepares for a warning. If it is determined that this is the second copy using the , it is determined in step (5147) whether or not the paper refeed cassette detection sensor (SelO) is on. If it is off, the paper refeed cassette (150) is connected to the paper refeed device main body (1
31) and set it in the paper feed section of the copying machine main body (1), and in step (514g>, the size nonconformity flag is reset to r□, and in step (514g>
5149), the paper feed port in which the paper refeed cassette (150) is set is selected.

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 lower paper feed cassette,
At step (5154), the size nonconformity flag is reset to r□, 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-stage paper feed unit (60) is connected, so if it is determined in step (5158) that the A register is equal to the paper size of the upper stage of the three-stage paper feed unit, then in step (5159) Set the size non-conformance flag to r
□, and at the same time select 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.

29th r5! J indicates a subroutine for processing automatic magnification selection executed in step (S7) of the main routine.

First, in step (5170), the vertical dimension of the document size data detected and transmitted by the CPU 3 that controls the ADF (80) is stored in the A register, and in step (5171), the horizontal dimension is stored in the B register. Store. Next, in step (5172), it is determined whether binding margin creation + automatic reduction mode display LED (264) is on or not, and if it is off, in step (5173), paper vertical dimension ÷ A register (w, Stacking size) is stored in the A register. If the display LED (264) is turned on, that is, if "binding margin + automatic reduction mode" is selected, then in step (5174) the value obtained by subtracting the binding margin from the paper vertical dimension is simulated. Store it in the C register as the 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 into account the binding margin. 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 of J1 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 copying machine is out of capability (outside the possible magnification range), the magnification incompatibility flag is set to 1 in step (5181).

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

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 (S862) is 10.
” is determined. If YES in both cases, the bin number of the first sorter (100) is incremented in step (S863). However, since the initial value of the bin number is '1', it is not incremented if the bin number is '1'.The bin number (101) of the first sorter (100) is sorted sequentially, and in step (5864) the bin number is 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 consecutive sorter.If it is a 0 multiple consecutive sorter, step (5865) is performed.
5866), set the bin number of the first sorter (100) to “1”
, and in step (S867) the second sorter (100a
) is not 1", increment the bin number.

Next, in step (586g) 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. 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 (5B71). 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 "al" in step (5872), and the over flag is set to "0" 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, then in step (5875) it is determined whether the grouping mode display LED (272) is turned on. If it is on, it is checked in step (S876) whether the paper detection sensor (Se16) is off-edge or not, and 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 1 final bin number + 1''.
If it is determined that the first
The bin number of the sorter (100) is returned to '1', and the bin number of the second sorter (100a) is changed to '1' in step (3883).
If the bin number is not 1", the bin number is incremented.

Next, in step (5884), if the bin number exceeds the maximum value [in the case of a multiple sorter, the second sorter (100a
)], the over flag is set to 11 in step (5885), and step (S886
), the first sorter (100) is set to non-sort mode, and the bin number of the second sorter (100a) is returned to 41''.

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).

FIG. 73 shows a subroutine for sorter motor processing executed in step (5804) of the main routine of (CPU 4').

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, 1;
In step (5891), the sorter motor is turned on, and in step (S892), the timer (process Q) is canceled.Next, in step (5893), the paper discharge detection sensor (Se5) is activated.
When the off-edge is confirmed, a timer (TQ') is started in step (5894). This timer (TQ
) has a preset time 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 (5895), step (589
6) Turn off the sorter motor.

(k-5, Control of paper refeeding device) Figure 74 shows the control of the paper refeeding device (130) (CPU
) shows the main routine.

When the (CPU) is reset and the program starts, first, at step <5900, the (RAM)

) is confirmed, that is, when the vapor starts to be conveyed into the paper refeed cassette (150) in duplex/composite copy mode, the motor (M6) is turned on in step (5932).
Turn on. Next, the sheet number counter is incremented in step (5933), the auto clear timer ffR) is reset in step (5934), and step (59
35) starts the paper length detection timer (IS).

Next, when off-edge of the sensor (Sell) is confirmed in step (5936), an auto-shut timer (Ill) is set in step (5937), and step (5936) sets the auto-shut timer (Ill).
93g), the vapor 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 completely ejected from the copying machine main body (1) is A4 horizontal feeding or not based on its length dimension 210mo+.

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

Next, in step (5940) the autoshaft timer (
When the completion of IU”) is confirmed, step (5941)
Turn off the motor (M6) with step (5942), and turn off the motor (M6) with
), when the end of the auto clear timer (TR) is confirmed, the switching flag is set to "1" in step (5943).

That is, the auto clear timer (TR) is set to be slightly longer than the set time of the paper length detection timer (TS) plus the paper transport interval time during continuous lobbying, and the auto shut timer (TU) is set to be slightly longer than the set time of the paper length detection timer (TS) plus the paper conveyance interval time during continuous lobbying, and the auto shut timer (TU) is set during continuous copying. is set slightly longer than the paper conveyance interval time. Therefore, if the paper is continuously fed during continuous copying, the paper length detection timer (TS) starts one after another in step (5935), and the motor (M6) is not turned off. , when one copy or the last copy of continuous copying passes the sensor (Sell), the auto-shut timer (TU'') ends and the motor (M6) is turned off in step (5941>). , the switching flag is set when non-standard size copy paper (other than A4 horizontal feed) is fed [step (5938),
When the auto clear timer (rR) ends, it is set in step (5942), rl, and instructs switching to the paper discharge tray mode in the subsequent subroutine.

951), it is determined whether the selected paper size is suitable (A4 horizontal feeding or not), and step
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) the 0 display L is used to determine whether the double-sided copy mode display LED (276) is on. 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.
