However, if the person in charge of copying makes a mistake in specifying specification mode 1-, for example, specifying the number of sheets to be bound incorrectly, or specifying the binding position of the staple needle incorrectly, Furthermore, even though it is bound in two places, -
If you accidentally specify the specification specification mode for the copying machine itself, such as specifying spot binding, or specifying the specification specification mode for the copying machine itself, such as enlarged or reduced 9-sided originals, the 20 copies of copy paper that came out will be , all the items are wasted, or you have to rebind them.

[Problem to be solved by the invention]

In the past, if such a series of specification modes were initially set, the automatic document circulation device, copying machine main body, copy paper finishing processing device, etc. would operate continuously.
This caused the above-mentioned inconvenience.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copying apparatus that can eliminate the above-mentioned disadvantages.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention sequentially feeds the originals one by one on the original storage table, passes through the original scanning section for exposure on the main body of the copying machine, returns them to the original storage table, and then feeds the originals one by one. When copying a part or more of copies after completing the copying of the number of sheets per set, the document automatic machine starts feeding the document again and repeats the document circulation cycle to return the document to the document storage table. In a copying machine that is equipped with a circulation device and a copy paper finishing device that finishes the copy paper of each part of the copy paper according to the set number of copies, the first part of the number of copies is A means for detecting that finishing of copy paper is completed, and an automatic document circulation device based on detection by the detecting means.

Means for temporarily stopping the copying apparatus main body and the copy paper finishing processing device, respectively, and means for making a person in charge of copying recognize that finishing of the first unit of copy paper has been completed based on the detection. This paper proposes a new configuration.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates the main body of an electrophotographic copying machine, 2 indicates an automatic document circulation device (RDH) installed on the top of the copying machine main body 1, and 3 indicates one side of the copying machine main body 1. A copy paper finishing device connected to each section is shown.

Furthermore, when performing one-sided copying, double-sided copying, reduced copying, enlarged copying, etc., select and press a designated mode button for executing these modes.

Further, after specifying mode 1~ for copying using a double-sided original, if the user wants to insert cover sheet 1~ in front of a partial unit of copy paper, the cover sheet insertion mode designation button 7C is pressed.

Here, in the automatic document circulation device 2, documents to be copied are circulated in the following manner.

In FIG. 3, assuming that the single-sided copy mode is specified and single-sided originals are used, a plurality of single-sided originals 11 are placed on the second side of the original storage table 1o. For example, in the automatic document circulation device 2 of this embodiment, the first page of the document is placed on the document storage table ]-0 with the image area facing downward;
The second page of the document is placed on top of this with the image portion facing downward, and this state continues until the final page. After all, in this case, the first page single-sided original is positioned at the bottom, and the final page single-sided original is positioned at the top.

Then, the document is sequentially fed by the lower feeding roller king 2 starting from the first page.

Symbol S is an area of the original scanning section for exposure on the copying machine main body side. After passing through this area, the original is sent in the direction of arrow E, after which it is reversed in the direction of arrow F and placed on the original storage table. Returned to 10. Each original that has been scanned is stored in the original storage table 10 with the image side facing down, but after copying a partial unit, each original is placed in the same page order as the previous one. Storage stand] It will be placed on O.

During this time, as will be described later, a mode is being executed in the copy paper finishing processing device 3 (FIG. 1) in which a portion of the copy paper is stapled.

When copying a portion or more of the original after completing the copying of a certain number of sheets, the original is again sequentially fed from the bottom by the lower feeding roller 12, and this series of circulation cycles is repeated for 20 minutes. In the case of specifying a section, it will be repeated 20 times in total.

Here, in FIG. 3, a partition water 13 is provided on the document storage table 10'2 so as to be able to move forward and backward from the site side. That is, in FIG. 4, assuming that one side of a partial unit of the original 11 (for example, the original from the first page to the last page) placed on the original storage table 10 is the part indicated by the symbol A, first , place a partial document on the document storage table 10, and then press the print button 5 shown in FIG.
retreats in the direction of arrow C, then moves up in the direction b using a driving means such as a solenoid or cam, and then advances further in the direction C, and is exposed to its own weight on the side edge side of the document on the topmost last page. It is designed to be ridden.

When the originals are sent one after another and the number gradually decreases, the partition claw ↓ 3 descends under its own weight, and either the last page of the original or the original storage table 1
After being sent from 0, the document is placed on the document storage table 10J2, and at this time, the partition water 13 turns on or off the switch 4 shown in FIG. In any case, the switch 4
It is possible to detect that the first part of the document circulation has been completed by the generation of the switching signal.

Figure 5 shows a schematic diagram of the copy paper finishing processing device.
In this example, the copy paper finishing processing device binds the copy paper using staples.

Copy paper that has been copied and comes out of the copying apparatus main body 1 (FIG. 1) advances in the direction of arrow d and enters the copy paper finishing processing device 3. When the copy paper is fed directly from this copy paper finishing processing device 3 to the next unit (for example, a sorter, etc.), the copy paper that has entered the copy paper finishing processing device 3 passes through the copy paper passage 15. and is discharged as is in the direction of arrow e.

Although not shown in FIG. 5, the copy paper path 15 is provided with a plurality of shifting rollers and side stoppers for aligning the copy paper by moving it toward the back. The side stops on the front side can be retracted into the passageway 15, and the copy paper can be brought to either of the side stops as required. Further, two sensors 132 and 133 are arranged in the copy paper path 15, and it is determined whether the copy paper has passed normally or not based on the time during which the copy paper passes.

When carrying out the mote for guiding and storing copy paper inside the copy paper finishing processing device 3 without ejecting it outside the copy paper finishing processing device 3, or performing the above-mentioned binding, the copy paper is guided by the deflection claw 16 to prevent its progress. force II'l] is changed and guided toward the copy paper path 17.

When the copy paper is directly led to the paper output tray 32 without the above-mentioned binding, the copy paper is transferred to the copy paper path 1.
7, the paper passes through the copy paper path 18, and is sent by a pair of transport rollers 19, 20 between a pair of transport rollers 24, 25 on the downstream side. Then a pair of paper ejection rollers 29
, 30 in the direction of arrow B.
It is stored in the second. At this time, the switching pawl 26 occupies the position shown in FIG.

The upper surface of the copy paper ejected to the paper output tray 32 is detected by the sensor 138, and the paper output tray 32 is controlled to operate in the vertical direction so that the upper surface of the stacked copy paper is always at a constant position. Ru.

In the above-mentioned binding mode, the deflection claw 22 is switched to the position shown in FIG. It is sent out in the direction of arrow H from between the endless belt 23 and the transport roller 19, which are constantly rotating in the direction of the arrow, and rides on the staple binding table 33 consisting of a fixed table 33A and a movable table 33B. In this mode, when the copy paper passes through the copy paper path 15, the copy paper is moved only by the side stopper located on the front side.

In FIG. 5, the reference numeral 34 is a stapler, which is movable in the direction of the arrow shown in the figure and in the direction perpendicular to the figure, depending on the size of the copy paper.

This stapler section is provided with two stapler sections, a first stapler section and a second stapler section, and each stapler section can move independently in the vertical direction. In addition, the above-mentioned movable table 33
B can move in the direction of the arrow in conjunction with the movement of the stapler 34.

In FIGS. 5 and 6, the copy paper discharged in the direction of arrow H and placed on the stapling table 33 is
With the copy sheets 100 aligned by the alignment stopper member 35 and all of the partial units placed on the stapling table 33, the stapler 34 moves to the desired stapling position and copies the partial units. Paper is bound together with staples. In this case, there are cases in which only one part is bound, and there are also cases in which two parts are bound.

When this binding is completed, the alignment stopper member 35 is retracted to the imaginary line position in FIG. 6. Note that the copy sheets discharged in the H direction are placed one by one on the staple binding table 33 by the shifting belt 36 shown in FIG.
The rotation of the stapler table 33 causes the stapler to be aligned with a side stopper (not shown) provided on the front side of the stapler table 33. In the end, consistency 1
- By means of the collar member 35 and a sight stopper (not shown), parts of the copy sheets are aligned and bound in a consistent state. The illustration of the shifting bell 1 to 23 is omitted in FIG. 6 to avoid cluttering the drawings.

A pair of conveyance rollers 24-. 25 and a switching claw 26 is held in the position shown in FIG. It is held between a pair of transport rollers 24 and 25 of unit h 37.

Both rollers 24 and 25 are driven to rotate in the direction of the arrow shown in the figure, and when the copy paper 00 is sent to the position shown by the imaginary line in FIG. When the copy paper 100 has advanced a predetermined distance after the detection, the rotation of both rollers is stopped, and the copy paper 100 is temporarily stopped at this position.

Note that among the pair of conveyance rollers 24 and 25, roller 25
is biased in the direction of arrow f by the elasticity of a spring (not shown), and is adapted to accommodate differences in the thickness of copy paper for each unit. Further, the switching pawl 26 occupies the position shown in FIG. 6 where it does not obstruct the entry of the copy paper 100.

As shown in FIG. 6, when a unit of copy paper 100 is stopped at the imaginary line position, the relay unit 37 is moved to the pivot 38.
7 in the counterclockwise direction in the figure and stop at the position shown in FIG.

In this state, the pair of transport rollers 24 of the unit 37.
．． 25 is placed in a position facing the pair of paper ejection rollers 29 and 30. Next, the conveyance rollers 24 and 25 on the relay unit 1-37 side rotate in the opposite direction, and accordingly, a unit of copy paper 100 is sent out from the relay unit h37 and delivered to the paper ejection roller 29.30. The paper is stored in the paper discharge tray 32 through the space between the paper sheets.

This series of operation cycles is repeated a set number of times, so that the set number of copies of copy paper is ejected.
・Since it is loaded and stored on the lay 32, there are 5 pieces. In this case as well, the paper ejection tray 32 is arranged so that the top surface of the stacked copy papers is always held at a fixed position.
When the top surface of the copy paper is detected by a sensor 138, its vertical position can be changed. Further, a paper ejection tray unit 3 equipped with a paper ejection tray 32, etc.
9 (Figure 5) makes it easy to take out the stacked and stored copy paper.

It can be pulled out towards the front of the drawing. For this purpose,
Slide rails 130, 131 are provided.

Here, if the person in charge of copying makes a mistake in specifying the specification mode for finishing or copying, for example, as mentioned earlier, the person in charge of copying may incorrectly specify the number of sheets to be bound in a certain unit, or In the past, if the binding position of the staple was specified to the wrong position, or if the reduction copy specification was changed to enlarged copy specification, conventionally, the copy paper finishing processing device 3 as described above is used. Because the finishing process was performed continuously for the set number of copies, all the copy paper that came out of the set number of copies was wasted or wasted.
Otherwise, it was necessary to rebind the paper.The present invention is designed to eliminate such problems.

Here, in FIGS. 1 and 2, various specification modes are specified using the buttons of the specification mode specifying section 7, and the number of copies, etc. is specified using the numeric keypad 6. After finishing, when the print button 5 is pressed, the original is repeatedly circulated in the JJil automatic circulation device 2, and a series of copying operations are performed in the copying machine main body 1, as described above, and the copy paper is In the finishing processing device 3, finishing processing of the copy paper, such as binding with staples, is performed.

By the way, as mentioned earlier, the switch 14 shown in FIG.
After outputting the switching signal in step 4, an appropriate timer is activated, and when a time limit signal is outputted by the timer after the elapse of time such that the above-mentioned binding of a partial unit of copy paper is completed, automatic document circulation device 2 and copying The apparatuses such as the apparatus main body 1 and the copy paper finishing apparatus 3 are temporarily stopped in operation. Electrical control means or other well-known means can be used as means for bringing the operation into a stopped state. Note that the document automatic shaft ring N2 is
Therefore, the next document circulation and the corresponding copying operation on the copying machine side are not performed.

By the way, the switch 14 and the timer described above serve as an example of means for detecting that the finishing of the first part of the copy paper has been completed, and based on the output of the time limit signal by the timer, For example, a message such as "Please check whether the copy paper is bound correctly" is displayed on the liquid crystal display section 8 shown in FIG. 2.

By looking at this, the person in charge of copying can make a partial copy.

Then, a portion of the copy paper discharged to the paper discharge tray 32 shown in FIG. 5 is taken out and checked to see if it is bound according to the specifications specified mode.

If there is no abnormality, press the print button 5 again.

After this, the series of operations described above in each device are performed for the remaining set number of copies. On the other hand, if there is an abnormality, the specification mode settings are redone and the print button 5 is pressed again. The rest is a series of operations in each of the devices above. By doing this, even if the person in charge of copying makes a mistake in selecting the specification mode or number of copies to be bound, only a portion of the copy paper will be wasted, and a large number of mistakes will be avoided. Copies are avoided.

In addition to the above-mentioned display method, other means for making the person in charge of copying aware of the fact that the finishing of the first unit of copy paper has been completed based on the above-mentioned detection are as follows: It is also possible to use a system that generates a notification sound such as a notification sound or a notification sound such as "P-J".Also, in the above embodiment, a copy paper finishing processing device of a type that performs binding with staples is applied, but a method that uses a punch The present invention can also be applied to a copy paper processing device that performs a combination of a series of functions such as punching holes or folding paper.

〔Effect of the invention〕

According to the configuration of the present invention, - When obtaining multiple copies of the same copy paper, even if the person in charge of copying specifies the wrong mode for copying or finishing specifications, some Only copy paper is wasted, and a large number of erroneous copies can be avoided, greatly contributing to reducing copying costs.
