Abstract

PURPOSE:To display an optimum sheet feed port when second copying in double/ composite copy mode, by a method wherein, when copying in a mode of containing copy sheets in a refeed sheet cassette is completed, a sheet port other than a sheet feed port stored in a memory means is displayed. CONSTITUTION:During first copying in a double/composite mode in that a sheet refeed device 130 is used, a selected sheet feed port 20 or 25 is stored in a memory 25. When it is confirmed that first copying is completed, if a memory sheet port is an upper sheet feed port 20, a select display LED for a lower sheet feed port 25 is flickered, and if the memory sheet feed port is a lower sheet feed port 25, a select display LED for the upper sheet feed port 20 is flickered. Thus, since, when second copying in a double/composite copy mode is effected, a sheet feed port other than the sheet feed port selected during first copying is displayed, a refeed sheet cassette 150 may be mounted to a sheet feed port by an operator. This constitution 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 that once receives copy paper ejected from the copying machine main body and then refeeds the copy paper from the paper feeding section of the copying machine main body. The present invention relates to a copying machine equipped with a paper refeeding device.

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

For example, JP-A-49-63441, JP-A-56-
Publication No. 95264 states that in order to enable double-sided copying with a simple operation, in a copying machine equipped with a U-turn path type paper path, a fully loaded cassette 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. A paper refeeding device is disclosed.

Furthermore, Japanese Patent Application Laid-Open No. 58-134659 discloses that in a copying machine equipped with a straight path type paper passage, a sheet storage cassette having a sheet storage opening and a sheet feeding opening is connected to a sheet ejection section and a sheet feeding section. A paper refeeding device that can be attached to and detached from the paper section by reversing its front and back sides has been disclosed.

However, in each of the above-mentioned paper refeeding devices, since the cassette itself can be 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 connected to the main body of the copying machine. The problem is that it is designed as a special product, and it is impossible to install it as an option in existing copying machines that do not have a paper refeeding device.

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

By the way, when copying in duplex/composite copy mode using this paper refeeding device, ■ Feeding paper from the normal paper cassette and storing it in the paper refeeding cassette (first copy) -
〇Insert the re-feed cassette into the paper feed slot → ■ Feeding paper from the re-feed cassette (second copy) - 〇Remove the re-feed cassette from the paper feed slot and reinstall it into the main body of the paper feed device. ■～■
The steps will be repeated. In this case, since the storage size of the paper refeed cassette is limited in step (■), it is preferable to feed paper from the same paper feed slot. The problem is how to install it. If you pull out the normal paper cassette installed in the paper feed slot selected in step ■ and then install the re-feed cassette, the paper cassette that was pulled out once again when performing step ■ again This requires the extra effort of re-installing it.

In order to solve the above problems, the copying machine according to the present invention has (a) a copying machine main body equipped with a plurality of paper feed ports, and (b) a paper refeeding device main body. a paper refeeding device having a paper refeeding cassette that is removable and detachable from the paper feed port of the copying machine main body, and can be installed in a paper discharge section of the copying machine main body or a non-sort paper discharge section of a sorter; (C) a storage means for storing a paper feed port selected during copying in a mode in which copy paper is stored in the paper refeed cassette; The apparatus is characterized by comprising a control means for displaying paper feed ports other than the paper feed ports stored in the storage means when copying is completed.

Effect In the above configuration, when copying using the paper refeeding device (double-sided copy mode or composite copy mode), 1
The paper feed port selected at the time of the first copying is stored in the storage means. Then, when the first copying is completed, paper feed ports other than the paper feed ports stored in the storage means are displayed. Therefore, when copying for the second time, the paper re-feeding cassette may be attached to the paper feeding port displayed as described above.

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-i, binding margin copy mode) In the binding margin copy mode, as shown in No. 10IyJ, 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 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), 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.

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 still unknown. Therefore, book scanning is not possible. Therefore, step <5

72) is also turned off, the display LED (273) is turned off in step (5817), and the display LED (273) is turned off in step (5817).
18) turns on the display LED (271). That is, each time the key (270) is turned on, the sorter operation mode is sequentially switched between 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 completely set in the paper refeeding device (130), the subroutine of sorter processing 1 is called in step (5820). Also, step (5821
) detects that the offset of the sensor (SelO), that is, the paper refeed cassette <150) has been completely removed from the paper refeed device (130), the subroutine of sorter processing 2 is called in step (5822). do.

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 or not, and in step (S825) 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 (S826). Similarly, in steps (S827) and (5828) the display L E D
If (276) and (278) are on, step (
5829) calls the sorter processing 2 subroutine.

Next, in step (5830), the paper refeed cassette (150)
), that is, the paper re-feed cassette <150) is determined to be the second hubby, and step (583
If it is determined in step 1) that the sorter operation mode is the non-sort mode, the second sorter (10

If it is not a multiple sorter, the non-sort mode display LED (273) is turned off in step (5833), and the grooving mode display LED (27) is turned off in step <5834).
2) is turned on, that is, the grouping mode is automatically selected as the first sorter (100). If it is a multiple sorter, the first sorter (100) is selected in step (5835).
Set to non-sort paper output mode. That is, the bridge (12
0) is lowered to the lower stage, and the paper sent from the non-sort path <110> of the first sorter <100) is discharged onto the paper discharge section (122).

FIG. 70 shows the steps (5820) and (5826)
The subroutine of sorter processing 1 executed in FIG.

First, in step <5840), the selected sorter operation mode is stored in memo 1 bar A), and in step (5841
) to determine whether or not it is a multiple sorter. If it is not a multiple sorter, the non-sort mode is displayed L in step (5842).
E D (273) is turned on, and in step (5843), the sorting mode display L E D (271) is turned off, and the grooving 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, the step (S
In step 845), the second sorter (100a) is set to non-sort mode, and in step (5846), the first sorter (100) is set to non-sort paper passing mode. That is, the bridge (120
) of the switching claw (123) to the upper level, and then move the first sorter (
The paper sent from the non-sorting path <110) of 100) is passed through the bridge (120) to the second sorter (too
a). The second sorter (100a) feeds the fed paper to the paper refeeding device (130) which is completely set in the non-sort paper discharge section.

FIG. 71 shows the steps (S822) and (S829)
The subroutine of sorter processing 2 that can be executed is shown below.

First, in step (5850), display the non-sort mode L.
Turn on E D (273) and step (5851)
When it is determined that the mode stored in the memory (A) is the sorting mode, the display LED (271) is turned on in step (5852), and the display is turned on in step (5852).
In step S853), first, the first bin is selected as the bin (101) to which paper is to be distributed. Step (5854
), if it is determined that the mode that has been completely stored in the memory (A) is the grouping mode, step (5855)
Then, the display LED (272) is turned on, and step (S853) is similarly executed. If the mode that has been completely stored in memory (A) is non-sort mode, step (S
856) to turn on the display LED (273),
In step <5857), the first sorter (100) is set to the non-sort paper discharge mode as in step (S835).

Figure 72 shows the main routine steps (CPυ4).
5802) shows a sort processing subroutine that can be executed.

First, if it is determined in step (5860) that the sorting mode display LED (271) is turned on, the paper detection sensor (Se16) set for sorting mode g (107) is turned on in step (5861). and whether the over flag indicating that the number of copies exceeds the number of bins in step <5862) is rO
1 or not. If YES in both cases, the bin number of the first sorter (100) is incremented in step (5863). However, since the initial value of the bin number is "1", if the bin number is "1", it is not incremented. The first sorter (100) is sequentially sorted into bins (101), and when it is determined in step (5864) that the bin number of the first sorter (100) has become "final bin number + 1", step (5865) is performed. Determine whether or not it is a multiple sorter. If it is a multi-unit sorter, step <
5866> to set the bin number of the first sorter (100)
, 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 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]. When the sorter (100a) is confirmed, 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,
If it is determined in step (5868) that the set number of copies has been ejected, the bin number of the second sorter (100a) is returned to "1" in step (S872), and the over flag is set to rO in step (5873). and returns the bin number of the first sorter (100) 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 (S875) 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)
In step 7), check whether the over flag is "r□" or not.
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. R, it is determined in step (5880) that it is a multiple sorter, and in step (5881) the bin number of the first sorter (100) is "last 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 (5883).
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 (3885), 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 step (5875) that the grouping mode display L ED <272) is turned off, the non-sort mode is selected in step (S887).

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

First, when it is confirmed in step <5890) that the paper discharge detection sensor <5ea) 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). do. Next, when off-edge of the discharge detection sensor (Se5) is confirmed in step (5893), a timer (TQ) is started in step (5894). This timer (TQ) has a preset time until the paper is completely 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) is executed.
Turn off the sorter motor.

(k-5, Control of paper refeeding device) Figure 74 shows how to control the paper refeeding device (130) (CPtJ
5) 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 (CPUUS) 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 main routine steps (
5902) shows a subroutine for power-on processing that can be executed.

First, when it is confirmed that 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 step (S923)
(5924), solenoid (162), (167)
Turn off. That is, when the power is turned on, a mode is first set in which paper is ejected onto the interleaving paper tray (145).

Figure 76 shows the main routine steps (
5903) shows a motor control subroutine that can be executed.

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 turned on in step (5931).
After confirming that the paper is on-edge, that is, when the paper starts to be conveyed into the re-feeding cassette (150) in duplex/composite copy mode, the motor (M6> is turned on in step (5932). Then, in step (5933) ) increments the number of sheets counter, steps <5934) resets the auto clear timer (IR), and steps (593)
5) starts the paper length detection timer (Is).

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
In step 38), the paper length detection timer (TS) 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 11'' 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 auto-shut timer (
When the end of TLI) is confirmed, step (5941)
Turn off the motor (positive) and step (5942)
When the end of the auto clear timer (TR) is confirmed,
In step (5943), the switching flag is set to 11''.

That is, the auto clear timer (IR') 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 copying,
The auto-shut timer (issue) is set to be 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) is started one after another in step (5935), and the motor (M6) is not turned off. Then, when one copy or the last copy of continuous copying passes the sensor (Sall), the auto-shut timer (Tu) ends.
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 (IR) ends, it is set to "1" in step 8 (5942), and a switch to the paper discharge tray mode is instructed in the subsequent subroutine.

FIG. 77 shows a subroutine for double-sided/composite selection processing executed in step <5904 of the main routine (CPL15).

First, in step (5950), when it is confirmed that the duplex copy select key (275) is on-edge, step (5950) is confirmed.
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, in step (S953), press the manual feed tray detection switch (SW9).
Determine whether or not is on. If it is on, that is, if it is determined that the manual tray 36) is closed and manual copying is not being performed, then in step (5954) it is determined whether the double-sided copy mode display LED (276) is on. If the display LED (276) is on, 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.

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)
When the on-edge of the composite copy select key (93) is confirmed, steps (5971) and (S972) are performed.

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 refeed cassette (ISO) has been pulled out from the main body (131), the sheet number counter is reset to "0" in step (Stool), and step <510
If the displays LED (276) and (278) are blinking at step 02), the blinking is stopped. At the same time, in step <51003), the over flag is set to "J%", and in step (51004), the paper jam flag is set to 102, and in step (
51005), the paper jam switching flags are reset to r□, respectively.

Next, in step <51006) it is determined whether the motor (M6) is turned on. If the motor (M6) is not turned on, step (51007), (510

Figure 81 shows the main routine steps (
5908), that is, the capacity over detection process executed in
A subroutine for detecting the loading amount of the paper refeed cassette (150) is shown.

First, in steps (51040) and (51041>), it is determined whether or not the display LEDs (276) and (278) are on, that is, whether duplex copy mode or composite copy mode is selected, and whether or not the two-sided copy mode or composite copy mode is selected is determined. If any one is selected, it is determined in step (51042) whether the count value of the number of sheets counter is greater than 70, and if it is smaller, the process returns to step <5104.
In step 4), it is similarly determined whether the count value is greater than 50 or not. In this embodiment, the loading capacity of the paper refeed cassette (150) reaches 70 sheets, and when it reaches 50 sheets, a preliminary display indicating that it is almost full [Display L E D <2
