Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a copying apparatus equipped with an automatic document feeder and a sorter.

(Prior art) A copying machine equipped with an automatic document feeder and a sorter (
If you want to continuously copy multiple groups of originals of different types, for example, if you want to copy the multiple groups in A,
Conventionally, it has been divided into B and C groups for convenience.
First, the originals of group A (multiple sheets) are loaded on the original feeding tray of the automatic original feeding device, and then the originals are automatically fed to the copying device, and the nuclear copying corresponding to this original is done page by page. After that, repeat the same work and operation for group B, and
As for the group, similar tasks and actions were repeated after the KB group.

In such a copying machine equipped with an automatic document feeder or a sorter, simply by placing multiple groups of documents one on top of the other on the document feed tray at the same time, the copy sheets are automatically sorted in the sorter for each group. Once stored, there is no need to pay any attention to the completion of copying for each group (-Not only that, you only have to set the originals once, and what's more, you can also load the copy sheets of each group from the sorter at the same time. It can be taken out in a separated state, which saves labor in this type of work.

(Purpose of the Invention) The present invention has been made in view of the need for saving lives, and by simply placing multiple groups of originals on the original feed tray, copy sheets are automatically transferred to the sorter for each group. It is an object of the present invention to provide a copying apparatus in which the divisions are generally housed.

(Configuration of the Invention) The configuration of the present invention will be described below based on one embodiment.

In the embodiment shown in FIG.
From there, the stacked originals 0 on the original feed tray 4 are fed by the paper feed belt 5 in a downward feeding manner, and the several fed originals are moved to the lowest position by the frictional separation action of the pair of separation rollers 6. Only one of the images is separated. After that,
This separated original passes through a pair of transport rollers 7, enters between a transport belt 8 and a contact glass 9 on the copying device 2, and is transported over the contact glass 9 by the transport action of the transport belt 8. and stops at a predetermined position on the contact glass 9.

The document scanning unit on the contact glass 9 performs illumination scanning on the document.
Ejected to 0. On the other hand, a plurality of copied sheets corresponding to the first original, for example, the first page of the original, are distributed and stored in the tray 3.

It should be noted that while a plurality of copies are being made, the original document to be copied remains stationary on the contact glass 9.

In FIG. 2, for the document O on the document feed tray 4, a detection mark I is inserted between each document group so as to separate each document group.

As shown in Fig. 6, a mark M is provided on the back side of this detection sheet I, and when the detection sheet I reaches the lowest position while the document is being fed, the mark M is ,
It is detected by a division reading sensor 12 which is rotated through the opening 4a of the document feed tray 4 and is made of, for example, a reflective photosensor, and this sensor 12 generates a division signal for dividing the manuscript into groups. It's become like this.

In this way, the detection sheet (2) having the mark M, the division reading sensor 12, etc. are used as division marks to separate the manuscripts into groups during this feeding process when multiple groups of manuscripts are loaded on the manuscript feeding tray 4. This constitutes an example of means for generating a signal.

FIG. 5 shows the details of the soak 3 connected to the cane copying device 2. Inside the sorter 6, a plurality of bins 13 for distributing and storing copied copy sheets are arranged in the vertical direction. There is. These bins 13 are divided into groups for each bin.

That is, in this embodiment, from the first pin unit U1 to the fourth pin unit
Up to the bin unit U4, it is conveniently divided into four units, each of which has six bins.

Here, the copied copy sheet (S) discharged from the copying device main body 2 by the paper discharge roller pair 14 passes through the receiving roller pair 15, the turn roller pair 16, and passes through the sheet thread w.
517, it moves through the pair of conveyor rollers 21, and during this time, the loading switching plate 18 provided at the position shown in the figure switches for each bin as shown in FIG. The items are stored sequentially from the top to the bottom. In the figure, reference numerals 19 and 20 indicate acceptance sensors, 19 indicates a light-emitting cord, and 20 indicates a light-receiving element. The pair of receiving sensors 19 and 20 detect the presence or absence of copy sheets, and this detection determines whether the sorter is in a used state or an unused state. It has become.

Here, as shown in FIG. 4, suppose there are 6 manuscripts in group A, AP, , AP2. AP3 is displayed, and the number of manuscripts in group B is 4, BP, , BP2.
BP3°BP is displayed, and if there are 3 manuscripts in group C, cpl, cp2. Detection count ■1. (2) Hold the document 2 in the position shown in the figure and place it on the document feed tray 4 (see FIG. 2).

In this state, assuming that the number of copies (repeat copies) of the valley manuscript is 5 for all manuscript groups, if you press the print button (not shown) on the copying device, the top copy of the A group will be printed. The lower document AP is sent toward the contact glass 9 (see FIG. 1), and this document is copied over five sheets.
In FIG. 5, one copy sheet is placed in each of the valley bins from the top first nohin 13 to the fifth bin (not shown) among the six bins of the first pin unit U1. They are distributed and stored one by one.

Next, the second original AP2 of group A is automatically fed, and in the same way, the copied copy sheets corresponding to this original 4'l4VC are transferred one by one to the first to fifth sheets of the first bin unit U1. Each document is distributed and stored in the bins, stacked on top of the previous document. Then, similar copying and copy sheet storage in the sorter are performed for the third document AP3.

At the above stage, the detection sheet {circle around (2)} reaches the lowest position, and its mark M is detected by the delimiter reading sensor 12. This detection generates a delimiter signal, and with this signal, B
Copied 1 corresponding to the first original 4 aP of the group
The 1st copy sheet is not placed in the 6th bin of the $1 pin unit U1, but is stored in the 1st bin of the 2nd bin unit U2.

Also, the remaining four copies are sorted in the second bin unit U2.
are respectively stored in the second to fifth bins. Note that the detection sheet (2) is sent toward the contact glass 9 as shown in FIG.

When the copying of all documents in group B is completed, the same (cut signal) is generated by detecting the mark on the second detection sheet ■2, and this signal is used as a control medium to copy documents in group C (CF2, CF2, 0P3). The corresponding copied copy sheets are distributed and stored in the first to fifth bins of the third pin unit U3.

In the above state, the first bin unit U1Vc stores the copy sheets corresponding to the documents in the A group in the 14th bin to the 5th bin, with the first page to the third page as one A.
They will be stored in the respective bins. That is, it is possible to conveniently obtain five copies of one set of copies from the first page to the third page.

Furthermore, from the second bin unit U2, one set of copies from the first page to the fourth page corresponding to the originals of group B can be obtained for five sets. Sara K
For the GC group as well, it is conveniently possible to obtain five sets of copies from the sixth bin unit U3.

The carry-in switching plate 18 is controlled by a control circuit (not shown) to selectively switch between the solid line and the imaginary line position as shown in FIG. The carry-in switching board 18 having such a function constitutes an example of copy sheet carry-in switching means that switches the carry-in of copy sheets from the relevant bin group to the next bin group when the separation signal is generated. are doing.

In the above description of the embodiment, the number of reheat sheets for each document group is set to five, but for example, a desired number of copies can be set for each group by making full use of an appropriate control program means. You can also do it.

In this embodiment, 24 bins 13 are provided for the sorter shown in FIG. 5, but in this case,
Instead of displaying the bin numbers of the sorter in a sequential manner such as numbers 1 to 24, if the bin numbers are displayed for each bin unit, such as numbers 1 to 6, it will be easier for the person in charge of copying to keep track of the copies of each group. It is easy to distinguish between sheets.In addition, it goes without saying that it can be used as a 24-bin sorter when there is no detection sheet for separation.In addition, the series of technologies described so far do not separate sheets without processing. It can also be applied to facsimiles, printing machines, etc. that perform

(Effects of the Invention) According to the present invention, copy sheets are sorted and stored in the sorter for each valley group by simply placing multiple groups of originals on the original feeding tray. Therefore, there is no need to perform the troublesome work of setting originals one by one in each group (this type of work is labor-saving, and there is no need to worry about copying documents separated into each group). (Can be taken out from the sorter instantly and at the same time.)
