Abstract

PURPOSE:To cause a final copy to automatically form a one side copy, by a method wherein, in the case of the odd number of documents and a double copy mode, a copying machine is worked so that a copy sheet for a first document is prevented from being contained in a refeed sheet cassette. CONSTITUTION:When a double copy mode by means of a sheet refeed device 130 is selected and it is inputted that the odd number of documents is placed on an ADF 80, a control device, when a first document detected by a sensor Se7 is copied, turns ON a solenoid to position a switch claw 160 of the sheet refeed device 130 to a lower stage, and a copy sheet is discharged on a discharge sheet tray 145 without being contained in a refeed sheet cassette 150. When a final copy for the first document is discharged and a copy sheet detecting sensor Se13 is brought into an OFF-state, and the solenoid is turned ON to switch the switch claw 160 to perform copy in an ordinary double copy mode. This constitution causes a first page to automatically form a single surface copy and improves facility.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying machine, in particular, to a copying machine that once receives copy paper that has been ejected from the copying machine main body, and then re-feeds it 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.

Conventional 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. 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 moves to the paper ejecting section and picks up the copy paper, and when copying to the back side, it moves to the paper feed section and the receiver refeeds the picked up copy paper. 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 is disclosed that can be attached to and detached from the paper section by reversing the front and back sides.

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 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, when such a paper refeeding device is used to copy an odd number of originals from the last page in double-sided copy mode, there is a problem that the final original (first page) becomes a single-sided copy. In such a case, the operator should not store copy paper in the refeeding device when copying the first original (last page), but instead load the copying paper from the next original into the cassette in the refeeding device. It is necessary to call attention to change the operation mode of the copying machine to accommodate the problem. However, if such operations are entrusted to the operator, selection or cancellation operations must be performed each time, which is complicated and may lead to operational errors.

Means for Solving In order to solve the above problems, the copying machine according to the present invention includes (a) a copying machine main body, and (b) a sheet refeeding device that is removably attachable to the copying machine main body. It has a refeeding cassette that can be attached to and removed from the paper feeding section of the copying machine, and a refeeding device that can be installed in the paper discharging section of the copying machine body or the non-sorting paper discharging section of the sorter, and (c) an odd number of originals. (d) If an odd number of originals is input and a double-sided copy mode using the refeeding device is selected, when copying the first original, The present invention is characterized by comprising a control means for operating the paper so as not to accommodate the paper in the paper refeed cassette.

In a New Year-Month or higher configuration, if an odd number of originals is input and the double-sided copy mode using the paper refeeding device is selected, when copying the front side of the first original,
The copy paper is controlled not to be stored in the paper refeed cassette, but to be stored, for example, on the paper discharge tray of the paper refeed device. This eliminates the need for the operator to reset the paper feeding mode each time, and it becomes possible to automatically create double-sided copies on the front and back from the first page.

A binding margin (e) of a specified width can be provided on the right side of the copy paper.0w If there is no margin in the manuscript, providing a binding margin can make it easier to bind the copy paper.

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 reduction rate is automatically calculated. Determine the copy magnification.

It is determined whether E D (264) is on or not, and if it is on, a subroutine for processing the introduction of a binding margin is called in 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. So I can't do book scan, so step <5
At step 26), the display LED is turned off, and at step (527), the book A side signal (265) and the book B side signal are reset to 10'', and the book copy mode is automatically canceled.

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 or not the number of binding allowances + 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 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 or not the paper 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 non-conformity flag to rl, and prepares for a warning. If so, or if it is determined in step (5145) that the second copy is made using the paper refeeding device (130), the paper refeed cassette detection sensor (SelO) is activated in step (5147). Determine whether it is on or not.” If it is off, the paper refeed cassette <150) is connected to the paper refeed device main body (

l! Then, in step (5172), it is determined whether the automatic reduction mode display LED (264) for binding allowance is on, and if it is off, in step (5173), the vertical dimension of the paper ÷ A register (original length) is determined. If 0 display L E D (264) is turned on, that is, if "binding margin + automatic reduction mode" is selected, the value of paper vertical dimension is stored in step (5174). The value obtained by subtracting the binding margin is stored in the C register as a simulated paper vertical dimension. In step (5175), the vertical magnification is calculated based on the above data and stored in the A register. As a result, the magnification factor is automatically calculated in consideration of 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 is stored in the C register as the copy magnification.

The copy magnification obtained in this way is determined in step (5180).

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, 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 1''1. in step (5870), and the first sorter <100 is set to non-sort mode in step (5871). If it is determined that the set number of copies have been ejected in step (586B), the bin number of the second sorter (100a) is returned to "1" in step (5872), and the over flag is set to 10 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 off, then in step (5875) it is determined whether the grooving mode display LED (272) is on. If it is on, in step (5876) it is determined whether the paper detection sensor (Se16) is off-edge or not, in step (587).
In step 7), check whether the over flag is 0 or not.
In step (78), it is determined whether or not the set number of sheets have been ejected. If YES, in step (5879), if the first sorter bin number is not '1', the bin number is incremented.Subsequently, in step (5879), the bin number is incremented. 5880), it is determined that it is a multiple sorter, and in step (5881), the bin number of the first sorter (100) is 4 final bin number + 1".

Further, if it is determined in step (5875) that the grooving mode display LED (272) is turned off, the 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 the on-edge of the paper discharge detection sensor (Se5) of the copying machine main body (1) is confirmed in step <5890), the sorter motor is turned on in step (5891), and the timer (TQ) is canceled in step (5892). Next, when off-edge of the discharge detection sensor (Se5) is confirmed in step (5893), a timer ('IQ) is started in step (5894). This timer (TQ)
The time required for paper to be conveyed through the path in the sorter (100) and distributed to each bin (101) is set in advance. Therefore, when the end timing of this timer is confirmed in step (5895), step (5896)

6), if it is determined that either of (278) is on, the detection sensor (Sell) is activated in step (5931).
After confirming that the paper is on-edge, that is, when the paper 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 (IR) is reset in step (5934), and step (593) is performed.
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 (IU) 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 completely 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 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 end of mu) 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 rl.

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 conveyance interval time during continuous copying, and the auto shaft timer (TU') is set during continuous copying. The paper conveyance interval time is set slightly longer than the paper conveyance interval time. Therefore, when papers are continuously conveyed during continuous lobbies, the paper length detection timer (Ts> is started one after another in step (5935) and the motor (6) is not turned off. When one copy or the last copy of continuous copying passes the sensor (Sall), the auto-shut timer (TU) ends and the motor (M6) is turned off in step (5941). Flags are non-standard size (other than A4 horizontal feed)
When copy paper is fed in [step (593g)
], the auto clear timer (IR) is set to ``Step (5942) 1.11'', 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 (
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, duplex copy mode has already been selected, and the current key (275)

After confirming that the sheet number counter is 0'' in step 965), 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 (5972) are performed.

Note that when the final copy of the first draft is ejected [YES in step (51064), the copy paper detection sensor (S
e13) is turned off, [Y in step (51065)
ESI, that is, when the copy paper is removed from the paper output tray (145), the solenoid (162) is turned on, the paper feeding mode of the paper refeeding device (130) is switched to the duplex/composite copy mode, and thereafter, Copy in normal double-sided copy mode.

With the above control, when copying in double-sided copy mode using the paper refeeding device (130), if the original has an odd number of sheets and copying starts from the last page, the last page will be one-sided. This solves the problem of single-sided copying from the first page.

Note that this shows a good effect when ADF (80) is used, but in the present invention, ADF (80) is used.
(80) is not necessarily necessary, nor is the sorter (100) necessarily necessary, but when copying the first original of an odd number of originals, the copy paper is ejected from the paper refeeding device (130). In the paper tray (145) (, sorter (
100).

As is clear from the above description, according to the present invention, there is provided a paper refeed cassette that is removable from the main body of the paper refeeding device and also detachable from the paper feed section of the main body of the copying machine. , a paper refeeding device that can be installed in a paper discharge section of a copying machine main body or a non-sort paper discharge section of a sorter;
When copying the first original, if there is a means to input that the original is an odd-numbered original, and if the odd-numbered original has been input and the double-sided copy mode using the refeeding device is selected, , is equipped with a control means that operates so that the copy paper is not stored in the paper refeed cassette, so when double-sided copying is performed from the last page of an odd-numbered original, the last page is automatically controlled to be one-sided copied, and the operator The operational effort can be saved, and the usability is improved.
