Abstract

PURPOSE:To prevent the occurrence of choking with a paper sheet, by a method wherein, through selection of a copy sheet, having size being too large to contain it in a sheet refeed device, by means of an automatic copy sheet selecting mechanism, copying motion is stopped to sound an alarm. CONSTITUTION:During duplication in a mode in which copy sheets are contained in a sheet refeed device 130, i.e., a double copy mode or a composite copy mode, a necessary copy sheet size is indexed from a document size, detected by means of a sensor Se8 of an ADF 80, and copy magnification by means of an automatic copy sheet selecting mechanism to select cassettes 62-64. In this case, when a copy sheet, detected by either a paper size detecting switch SW17-20, SW21-24, or SW25-28, of the selected cassette has a size being too large to contain it in the sheet refeed device 130, a control device stops motion of a copying machine and alarms. This constitution enables prevention of the occurrence of a trouble, e.g. choking with a sheet.

Description

Detailed Description of the Invention: February 11, 2013 The present invention is directed to a copying machine, in particular, to a copying machine that once receives copy paper discharged from the copying machine main body, and then re-feeds the paper from a paper feeding section of the copying machine main body. The present invention relates to a copying machine equipped with a paper refeeding device that enables paper refeeding.

Prior Art and Intervening Points Generally, 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 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. 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 path 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).

Incidentally, in recent years, an automatic copy paper selection mechanism that determines the required copy paper size from the original size and copy magnification has been provided, and the above-mentioned paper refeeding device can be applied to a copying machine equipped with this mechanism. Conceivable.

However, since the size of copy paper that can be accommodated in the paper refeeding device is limited, there may be cases where copy paper of the size selected by the automatic copy paper selection mechanism cannot be accommodated in the paper refeeding device. If you perform a copying operation, paper jams may occur.

In order to solve the above problems, the copying machine according to the present invention includes: (a) *An automatic copy paper selection mechanism that determines the required copy paper size from the document size and copy magnification; (b) a paper refeeding cassette that is removable from the paper refeeding device main body and also removable from the paper feeding section of the copying machine main body; (c) an automatic copy paper refeeding device that can be installed in a non-sort paper discharge section of the sorter; The present invention is characterized by comprising a control means that stops the copying operation and issues a warning when the selection mechanism selects copy paper of a size that cannot be accommodated in the paper refeeding device.

In configurations older than New Year and January, when copying in a mode that stores copy paper in the paper refeeding device (duplex copy mode or composite copy mode), the automatic copy paper selection mechanism will prevent copies of sizes that cannot be stored in the paper refeeding device. Once paper is selected, the copying operation stops and
In addition, a warning to that effect is issued to the operator. This prevents problems such as paper jams in the paper refeeding device.

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 FP mode, Anamo copy mode, and Book copy mode.

(h-1, IC 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 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.

(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, Anamo biased magnification (! horizontal 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.

1. Control of the copying machine main body) FIG. 24 shows the main routine (CPU 1) that controls the copying machine main body (1).

When (CPul) 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 (CPUI) is started. This internal timer determines the time required for one routine of this main routine, and its value is set in advance by 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 (CPU2) etc. is performed in step (514'), and step ( At step 515), the process waits for the internal timer to end and returns to step (S2). This long 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 (S3) of the main routine.

First, in step (520') it is determined whether or not the manual feed tray detection switch (SW9) is on-edge. If it is on-edge, that is, when the manual feed tray (36) is opened, the manual feed copy display LED is turned on in step (521). (23
2) is turned on, and in step (522) 40" is displayed 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 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 binding allowance, and in the case of manual copying, it is not known what size (length) of paper can be inserted. Therefore, the binding margin + automatic reduction mode is automatically canceled.

Next, in step (S25), 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 number 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 (SW9) is on edge, that is, it is detected that the manual feed tray (36>) is closed, the manual feed copy display LED (232) is turned off. At the same time, a is displayed in the copy number display segment (221) in step (530).

After confirming that the upper cassette has been pulled out in step 42), if the upper cassette is not selected, proceed to step 543.
) to confirm that the lower cassette is removed, then proceed to step (5).
44) allows the copy magnification to return 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 position of the selected cassette before the selected cassette was pulled out, will no longer be able to be calculated once the cassette is pulled out, so it will automatically return to the original magnification. .

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 lower paper feed selection display LED (2

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

First, in step (5140), the document size data detected and transmitted by the CPU 3 that controls the ADF (80) is temporarily stored in the A register.
In step (5141), it is determined whether the binding allowance + 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 selected at that time.
In step (5143), the original copy magnification [copy magnification ÷
(selected paper length - binding margin) 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 paper refeeding device (130) is used for the first set, 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 non-conformity flag to 11'', and prepares for a warning. If it is determined that the second copy is to be made using , 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
It is determined that the paper has been taken out from the printer (31) and set in the paper feed section of the copying machine main body (1), and the size nonconformity flag is reset to r□ in step (5148).
5149) selects the paper feed port in which the paper refeed cassette <150) is fully 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)
At step 151), the size mismatch flag is reset to "O", and at step (5152), the upper paper feed opening 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 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 11'' 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 I.
It is reset to "0" and the upper stage of the three-stage paper feeding unit is selected 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 rOyo in step (5162), and in step (5163) the paper size in the three-stage paper feed unit is Select the middle row. 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 "rO" in step (5165), and the size mismatch flag is reset to "rO" in step (5165).
66) selects the lower stage of the three-stage paper feeding unit.

The 29th [ffl] 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 or not the automatic binding mode reduction mode display LED (264) is on, and if it is off, in step (5173), the paper vertical dimension ÷ A register (W , , document vertical dimension) is stored in the A register. If 0 display LED (264) is turned on, that is, if ``binding margin + automatic reduction mode'' is selected, step (5174) is executed. The value obtained by subtracting the binding margin from the paper vertical dimension 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. This automatically calculates the magnification taking into account the binding margin.Similarly, step (S176): calculate the horizontal magnification "c" and store it in the B register.

Next, in step <5177), the values of the A register and B register are compared, and in steps (5178), (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. 7z shows a subroutine for sorting processing executed in step (5802) of the main routine (CPt14).

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 (5e16) 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 set to "O".
” is determined. If YES in both cases, the bin number of the first sorter (100) is incremented in step (sg63). However, since the initial value of the bin number is "1", if the bin number is "1", it will not be incremented; it will be sorted sequentially into bin (101) of the first sorter (100), and the 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 multi-continuous sorter.
At step 866), the bin number of the first sorter (100) is returned to "1", and at step (5867), if the bin number of 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 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 (5871). Also,
When it is determined that the number of copies set in step (5868>) has been ejected, the bin number of the second sorter (100a) is returned to ``1'' in step (5872), and the over flag is set to ``1'' in step (5873). In step (5874), the bin number of the first sorter (100) is reset to "1".

On the other hand, if it is determined in step (5860) that the sorting mode display LED (271) is out of date, it is determined in step (5875) whether or not the grooving mode display LED (272) is on. do. 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 10" 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 multi-continuous sorter, and in step (5881), the bin number of the first sorter (100) is "a final bin number + 1".
If it is determined that the first
Return the bin number of the sorter (100) to 1'' and step (
5883), the bin number of the second sorter (100a) is '1'.

Next, in step (58B4), if the bin number exceeds the maximum value [in the case of a double sorter, the second sorter (100a
), the over flag is set to "1" in step (saa5), and step (5886
) puts the first sorter (100) 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 that can be executed.

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 (IQ) is canceled in step (5892). Next, when off-edge of the discharge detection sensor (Se5) is confirmed in step (S893), a timer (TQ) is started in step (5894). This timer (TQ) is preset for the time it takes for the paper to be conveyed through the passage in the sorter (100) and distributed to each bin (<101). Therefore, when the end timing of this timer is confirmed in step (5895), step (5896)
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)
clear, initialize various registers, and make initial settings to put each device into its initial mode.

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

Next, each subroutine shown in steps (5901) to (5910) is called in sequence, and when the processing of all subroutines is completed, in step (5911')
) and performs other processing such as communication with step (59).
12), wait for the internal timer to end, and then proceed to step (5).
Return to 901). The time length of one routine is used to count the various timers that appear in each subroutine.

Figure 75 shows the main routine steps (CPU5).
5902) shows a subroutine for power-on processing executed in step 5902).

First, when the power is turned on in step (5920), the double-sided copy mode display LED (276) and composite copy mode display LED (278) are turned off in steps (5921) and (5922), and in step (5923),
Solenoid <162> at (5924), (167)
Turn off. That is, when the power is turned on, a mode is first set in which paper is ejected to the paper ejection tray (145).

Figure 76 shows the main routine steps (CPU5).
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 (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 starts 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 (TR) is reset in step (5934), and step (593)
Step 5) starts the paper length detection timer (TS).

Next, when the off-edge of the sensor (Sell) is confirmed in step (5936), the autoshaft timer (TU) is set in step (5937), and the
5938), 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 the 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 (
When the end of TU) 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 flag is set to "1".

That is, the auto clear timer (IR) 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 (Ill) can be set slightly longer than the set time of the paper length detection timer (TS) plus the paper transport interval time during continuous copying. It has been set slightly longer than the paper conveyance interval time. Therefore, when the paper is continuously conveyed during continuous copying, the paper length detection timer (rs) is started one after another in step (5935), and the motor (M6) is not turned off. When the last sheet of sheet copying or 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)], r1. is set to instruct switching to the paper output tray mode in the subsequent subroutine.

5951), it is determined whether the selected paper size is suitable (whether A4 horizontal feeding or not), and step (
5952), 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 paper refeed cassette (150), which is 70 sheets. If both are YES, press the manual feed tray detection switch (SW9) in step (5953).
Determine whether or not 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, it is determined in step (5954) whether or not the double-sided copy mode display LED (276) is on. If the display LED (276) is on, the duplex copy mode has already been selected, and the current key (275)
) is the second key operation, so 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 (278) and step (5
968), 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)

With the above control, if the automatically selected copy paper size is not a size that can be accommodated in the paper re-feed cassette (150), such copy paper will not be fed into the paper re-feed cassette (150). This will bring the situation to a halt.

As is clear from the above description, the present invention includes a copying machine body equipped with an automatic copy paper selection mechanism that determines the required copy paper size from the original size and copy magnification, and a re-feeder. The paper refeeding cassette is removable from the paper device main body and is also removable from the paper feeding section of the copying machine main body, and is installable in the paper discharging section of the copying machine main body or the non-sort paper discharging section of the sorter. a paper device, and copy paper of a size that cannot be accommodated in the paper refeeding device by the automatic copy paper selection mechanism when copying in a mode in which the automatic copy paper selection mechanism is activated and copy paper is stored in the paper refeeding device. Since the automatic copy paper selection mechanism is equipped with a control means that stops the copying operation and issues a warning when the selection is complete, even if the automatic copy paper selection mechanism selects copy paper of a size that cannot be accommodated in the paper refeeding device, such copying Since paper is not sent to the paper refeeding device, problems such as paper jams can be prevented from occurring, and usability is improved.
