Next, the operation of the above embodiment will be described.

First, in order to explain the operation of the sorter 10, FIG.
The principle of grouping sheets according to the present invention will be described with reference to FIG.

FIG. 2 shows a case where four sheets, that is, four pages of originals are supplied to the copying machine C and five sheets of copying paper are obtained from each original. It is well known that the paper grouping method includes a collation in which the pages of the original are arranged in order and a sorting in which the pages are arranged for each page, and FIG. 2 shows the case of the collation.

First, how the sheets are supplied and divided into groups will be described.

Here, it is assumed that the originals are a, b, c, d in order, and the sheets of each original (page by page) are numbered 1, 2, ...

First, when the first sheet a ₁ of the first original is supplied, it stops at the position indicated as the first copy as shown in FIG. This stop position (phase) may of course be stopped by a predetermined pulse after being detected by a sensor during conveyance, of course.
At this position, the regulation roller 31 which is the tip regulation means stops the movement, but this will be described in more detail later.

Now, the second paper a ₂ of the same first original is the first paper
The leading edge regulating means is advanced so as to stop before a predetermined deviation amount (phase difference) ΔL from the paper a ₁ . The leading edge regulating means is not only to stop the second sheet a _2, the first sheet a ₁ is intended to prevent the positional deviation by the progress of the second sheet a ₂ occurs. Similarly, the third sheet a _{3 and the} following sheets are fed, and each sheet is placed with a deviation amount of ΔL.

Now, with respect to the first paper b ₁ of the next second original,
The stop position of this is the first part shown in the figure as the first copy.
Original in the same place as the first stop position paper a _1, but for the stop is can I retracting said tip restricting means, in this state is the fifth paper a ₅ of the first document with the progress of the first sheet b ₁ It is hung up and causes a position shift. Therefore, near the trailing edge of the sheet, a rear portion holding unit 23 that holds the rear portion of the sheet is provided. The operation of the means 23 will be specifically described as the pressing roller 24 in the latter stage, but here, the operation will be described as the rear part holding means.

As the first sheet b ₁ of the second document advances, the leading edge regulating means retreats to the position of the first copy, but the rear holding means in FIG. 2 shows the fourth holding position, that is, the first holding position. only to suppress the fifth rear paper a ₅ document is sufficient. Further, when the progress of b _{1 is} completed, the tip regulating means is b ₁
Since the uppermost sheet is being held, the rear holding means can be released after b ₂ .

The entry of the second original sheet below the second sheet b ₂ is similar to the entry of the second original sheet below the second sheet a ₂ and the fifth sheet b ₅
The operation after mounting may be performed in the same manner as above.

When the sheets thus grouped and stored are taken out, the rear holding means is first advanced to the illustrated first holding position regardless of the taking-out means, and each original (or each page) is moved. The rear part of the second paper a _{2 to} d ₂ (next phase) or less is suppressed. Thus each first paper,
That is, only one set prepared for each manuscript or each page can be freely drawn.

The operation of the sorter 10 of FIG. 1 to which the above principle is applied will be described with reference to FIGS. 3 to 9.

When the power of the copying machine C is turned on, the sorter 10
The sides are also initialized at the same time, and the front unit 30 occupies the initial position (HP). When the paper size is input, the clutch device 37 is disengaged and the drive motor 28
Drives the ball screw rod 27 to adjust the position of the rear holding means 23. By this adjustment, the distance between the regulation rollers 31a and 31b as the leading edge regulation means and the pressing roller 24 as the rear portion retaining means is L (L ₀ + α) with respect to the sheet size L ₀ .
Made in. Here, α is appropriately determined with respect to the deviation amount ΔL, and is, for example, 1/2 or 1/3 of ΔL.
And so on.

When the above adjustment is completed, the front unit 30 and the rear unit 20 are reconnected by the clutch device 37, and both are simultaneously driven by the drive motor 28.

Then, the first manuscript (or the first page)
When the first sheet (first set) is fed, this sheet (assumed to be a _{1 according} to the above description) is captured by the deflection guide 21 of the rear unit 20 via the reverse conveyance path 12 and the horizontal conveyance path 14, and is deflected. Loading tray 18 by roller pair 22
Sent up. The leading edge of the sheet is the regulation roller 31a,
The deflecting roller pair 22 is stopped at the time when a minute time is added to the timing of being nipped by b, and the sheet a ₁ is slightly bent and then placed on the placing tray 18.

Then, the second sheet a ₂ is sent in the same manner, and during this conveyance, the front unit 30 is driven by the drive motor 28 together with the rear unit 20 as shown in FIG. In this embodiment, the second sheet a ₂ is stored in the state shown in FIG. 4 by moving backward by 30 mm.

In this way, as shown in FIG. 5, the parts up to the n-th part are successively stored. If this n is 5 parts as described above, the total deviation amount is 30 mm × 4 = 120 mm.

Next, the drive motor 28 is rotated in the reverse direction to receive the second page (second document), and the front unit 30 and the rear unit 20 are moved to the HP of the front unit 30. At this time, the pressing roller 24 is in a position to hold the rear portion of the previously stored sheets of paper a ₂ or smaller as shown in FIG.
Of course, since the top paper a ₅ is suppressed, the first paper b ₁ of the second original is
There is no problem in entering the.

In this way, the second page of paper is
For example, when the fifth part b ₅ is stored (FIG. 7), the front and rear units 30, 20 are returned to the HP again to receive the third original sheet, and thus the nth page, for example, the fourth page sheet. d
Accommodates a ₁ to d ₅ (FIG. 8, FIG. 9) ending the storage of all the paper.

When the storage of all sheets is completed, the drive motor 2
The front unit 30 and the rear unit 20 are moved forward by 8 and stopped at a predetermined stop position before the HP, for example, 10 mm before (FIG. 10).

[0045] In the above state, the regulating roller 31a, b is nipping the paper a ₁ to d ₁ of the first copy of the whole document, whereas the pressing roller 24 of the original content (or of each pages) second The paper (second copy) and below are pressed onto the loading tray 18.

Then, an ejection drive motor (not shown) is operated to eject the sheet by the regulation rollers 31a and 31b which are also sheet ejecting means (FIG. 11).

Then, the drive motor 28 drives the front unit 30 and the rear unit 20 to ΔL, that is, 3 in this example.
When it is moved backward by 0 mm, the sheets a _{2 to} d ₂ of the second page are nipped by the regulation rollers 31a and 31b, while the pressing roller 24 pushes the rear portion of the third sheet and the sheets below onto the placing tray 18. Therefore the same manner as described above regulating roller 31a, to start the b for discharging the sheet a ₂ to d _2.

In this way, the n-th sheet of paper, for example, a _{5 to} d ₅ is sequentially ejected.

The above shows the case of the collating operation. In the case of sorting by page, the regulating rollers 31a and 31b are stopped for each page, and after storing a desired number of sheets, The shift amount ΔL may be moved to store the next page. The discharging of the stored sheets is the same as in the case of the collation described above.
