Description

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

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

For example, JP-A-49-63441, JP-A-56-
Publication No. 95264 states that in order to enable double-sided copying with a simple operation, in a copying machine equipped with a U-turn path type paper path, a cassette installed in the paper ejection section is inserted between the paper ejection section and the paper feed section. When copying to the front side, it can be moved to the paper output section and the copy paper is picked up by the receiver, 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 path type sheet passage, a sheet storage cassette having a sheet storage opening and a sheet feeding opening is used as a sheet ejection portion. A paper refeeding device is disclosed that can be attached to and detached from a paper feeding unit by allowing the front and back sides to be reversed.

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 document feeder has been provided that automatically feeds a large number of stacked originals one by one onto the document table glass of the main body of a copying machine. It is conceivable to apply the above-mentioned paper refeeding device.

Normally, if the copying machine has a built-in automatic duplex copying function, the copying machine itself will automatically prepare for refeeding (second copying), so the automatic document feeder will All you have to do is feed the original.

However, in the above-mentioned paper refeeding device, after the first copying is completed, the operator must remove the paper refeeding cassette from the paper refeeding device and attach it to the paper feeding section of the main body of the copying machine. Therefore, if the copying machine main body and automatic document feeder cannot be linked to such operations, the operator will have to input each time to the copying machine that it is the second copy or to start the document feeding operation. This is complicated, and there is a risk of operational errors occurring.

In order to clearly resolve the problems beyond the means for solving the problems, the copying machine according to the present invention has the following features: (a) a copying machine main body; (b) an automatic document feeder installed on the copying machine main body; (c) a paper refeeding cassette that is removably attachable to the main body of the paper refeeding device and also detachable to the paper feeding section of the copying machine main body; (d) storing the copy paper in the paper refeeding cassette; after the first copying is completed, the paper refeeding device is installed in the paper feeding section of the copying machine main body; <6) a control means for automatically starting a second copying operation when the detection means detects that the paper re-feeding cassette is installed in the paper feeding section of the copying machine main body; It is characterized by having the following.

Effect In the above configuration, when copying is performed in duplex/composite copy mode using the automatic document feeder and the paper refeeding device, the paper refeeding cassette is loaded after the first copy is completed. When it is fully inserted into the paper feed section of the copying machine, the second
The second copying operation is started. This eliminates the need for the operator to input the fact that it is the second copy and the document feeding operation, and prevents operational errors.

After a certain period of time has elapsed since the motor (M6) is activated and the timer is activated when the trailing edge of the copy paper is detected, that is, after the time has elapsed for the copy paper to be completely stored in the paper re-feed cassette (150), the motor (M6) is activated. It is designed to stop the operation of li6). 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. 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 pawls (160), (165) and the on/off control of the solenoids (162), (167) will be explained with reference to FIG.

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, binding 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 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 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, the analog magnification (aspect ratio) is 95
If it is not within the range of ~105%, the resolution will drop, so if a bias rate outside of this range is specified, a warning will be given to the operator on the display section (220), which will be described below.

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

When the (CPUI) is reset and the program starts, first, in step (Sl), initial settings are made to clear the (RAM), initialize various registers, and put each device into the initial mode. In (S2), an internal timer of (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 (CF'υ2> 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).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 copy display LED (23

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 can be inserted? Since I don't know, I will automatically cancel the binder's automatic reduction mode.

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. So I can't do book scan, so step <5
26> turns off the display LED, and in step (S27), the book A side signal (265) and the book B side signal are turned off.

In 4), the copy magnification is restored to the original magnification (before automatic reduction), in step (545) the magnification is displayed, and in step (546), the magnification is sent to (CPU 2). 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, can no longer be calculated by pulling out the cassette, 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 (S49), the paper feed slot (20) and (
25) is automatically selected and the upper paper selection display L

If it is off, the A register is multiplied by the copy magnification in step (5142), that is, the vertical length and width of the document stored in the A register are multiplied by the magnification. If it is on, this magnification is the copy magnification that was calculated based on the 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 value is multiplied by the A register in step (5144).

Next, in step (5145), it is confirmed that the first copy is to be made using the refeeding device (130), and in step (5146>), the size of the refeeding cassette (150) is calculated as described above. It is determined whether the size matches the paper size stored in the A register. If it does not match, the process immediately moves to step (5157), sets the size incompatibility flag to I"1", and prepares for a warning. , or if it is determined in the step (5145) that the second copy is to be made using the paper refeeding device (130), the paper refeeding cassette detection sensor ( If it is off, the paper refeed cassette (150) is connected to the paper refeed device main body (SelO).

In step 229), the anamorphic rate memory is corrected to 0.64, and in step 5233, the change flag is set to "1".

In addition, if it is determined in step (5222) that the binding margin copy mode select key (212) is on, that is, the magnification down key (202) is turned on while the binding margin copy mode selection key (212) 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), set the change flag to "1.

150) is set in the paper refeeding device (130), the sorter processing 1 subroutine is called at step (5820). Also, step (5821
) detects the offset of the sensor (Sel O), that is, the fact that the refeeding cassette (150) has been taken out from the refeeding device (130), calls the sorter processing 2 subroutine in step (5822). .

Then, 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, and in step <5825) the composite copy 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 has been selected, the subroutine of sorter processing 1 is called in step (5826). Similarly, in steps (5827) and (5828) the display L E D

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. Whether or not the over flag indicating that the number of copies exceeds the number of bins in step (5862) is rO
” is determined. If YES in both cases, the bin number of the first sorter (100) is incremented in step <5863). However, the initial value of the bin number is "1", so if the bin number is "1", it will not be incremented.The first sorter (100) will be sorted sequentially into the bin (101), and in step (5864) the bin number will be incremented. When it is determined that the bin number of the 1 sorter (100) has become "last bin number + 1", it is determined in step (5865) whether or not it is a continuous sorter.If it is a 0-fold continuous sorter, step (
5866) returns the bin number of the first sorter (100) to 1", and in step (5867) returns the bin number of the second sorter (100a).
If the bin number is not "1", that 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, step (5869) determines that the bin number has exceeded the maximum value [! In the case of a double sorter, if the second sorter (100a) is confirmed, the over flag is set to 11 in step <5870), and the first sorter (100) is set to non-sort in step (5871). mode. Further, 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 reset to "0" in step (5873), and the first sorter (100) is set in step (5874).
Return the bin number to ``1''.

On the other hand, if it is determined in step (5860) that the sorting mode display LED<271> is turned off, it is determined in step (5875) whether or not the grooving mode display=LED (272) is turned on.

If it is on, it is checked in step (5876) whether or not the paper detection sensor (Se16) is off-edge.
77), check whether the over flag is 10'' or not in step (5).
In step 878), 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 (58s1), the bin number of the first sorter (100) is 'final bin number + 1.
”, the bin number of the first sorter (100) is returned to “1” in step (5882), and the bin number of the second sorter (100a) is returned to “1” in step (5883). 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
), the over flag is set to "1" in step (5885), and step <5886
) puts the first sorter (100) into non-sort mode and returns the bin number of the second sorter (100a) to "1".

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

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 main body (1) is on, 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 (Se5)
When the off-edge is confirmed, a timer (TQ) is started in step (5894). This timer (IQ'
) is set in advance as the time it takes for the paper to be conveyed through the path in the sorter (100) and distributed to each bin (101). Therefore, when the end timing of this timer is confirmed in step (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 (CPU5) is reset and the program starts, first, in 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 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). 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 (
5902) shows a subroutine for power-on processing that can be executed.

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),
(5924), solenoid (162), (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 (
5903) shows a motor control subroutine executed in step 5903).

First, in step (5930) the display L E D (27
6), (278) is on, the detection sensor (Sell) is turned on in step (5931').
) is confirmed to be on-edge, that is, when paper 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 (IR') is reset in step (5934), and step (5933) is performed to reset the auto clear timer (IR').
935) starts the paper length detection timer (Is).

Next, when off-edge of the sensor <5ell) is confirmed in step (S936), an auto-shut timer (TU) is set in step <5937), and step (59
In step 38), the paper length detection timer (Is) determines whether the paper length is 210 mm. Since this paper refeed cassette (150) is exclusively for A4 horizontal feeding, it is determined whether the paper ejected from the copying machine main body (1>) is A4 horizontal feeding or not based on its length dimension of 210 mm.

If it is not A4 horizontal feed, the switching flag is set to rl in step (S939). 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 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 (S943), the switching flag is set to 11''.

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 lobbying, and the auto shaft timer (IU) can be set slightly longer than the set time of the paper length detection timer (TS) plus the paper conveyance interval time during continuous lobbying. is set slightly longer than the paper conveyance interval time. Therefore, when paper is continuously conveyed during continuous copying, the paper length detection timer <Is) is not started and the motor (M6) is not turned off one after another in step (S935). Then, when one copy or the last copy of continuous copying passes the sensor (Sell), the auto shaft timer (TU) ends.
The motor (M6) is turned off in step (5941).

In addition, the switching flag is activated when copy paper of a non-standard size (other than A4 horizontal feed) is fed [step (593g)]
, when the auto clear timer (TR) ends [step (5942)], it is set to 11'' and instructs switching to the paper discharge tray mode in the subsequent subroutine.

Step 5951) determines whether the selected paper size is suitable (whether A4 horizontal feeding or not), and then proceeds to 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, then in step (5954) a 0 display is displayed to determine whether the double-sided copy mode display LED (276) is on. If L E D (276) is on, duplex copy mode has already been selected, and the current key (275)
