Abstract

PURPOSE:To distinguish an interrupting copy simply and clearly by controlling the operation so as to change the discharge position of the interrupting copy with respect to bins from that of a pre-interruption copy. CONSTITUTION:In a collator unit, the copies conveyed out to a sorter from a copying machine are guided to collating section provided with many bins in multiple stages through a receiving guide 7 having a pair of receiving rollers 6 and a skew roller 13, a pair of intermediate rollers 15, etc. When an operator turns an interrupting key on so as to copy other domuments during sort-copying, a solenoid 26 is driven. Thereby, a positioning member 23 is displaced to the left to the broken-line position against springs 24, 25. Then, the subsequent copy 23 is pinched by the pair of intermediate rollers 15 at a position E, its discharge position to the bin is made different from that of pre-interruption copy, thus both copies can be easily distinguished.

Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a collating device.

[Prior art]

2. Description of the Related Art In recent years, collating devices linked to copying machines have become widespread, and it has become easy to make copies of a document consisting of multiple sheets one by one.

Such copying uses the device for a long time and often requires copying other documents in between, in which case it is necessary to copy other documents in so-called interrupt copy mode.
, is discharged to a collating device.

Conventionally, when making an interrupt copy, in order to distinguish between the copy before the interrupt and the interrupt copy, the interrupt copy is output to an unused bin of the collating device, or a blank sheet is printed before outputting the interrupt copy. The conventional method is to eject one sheet of the pre-interrupt copy on top of the pre-interrupt copy, and then eject the interrupt copy into the same bin as the pre-interrupt copy.

However, among the conventional methods, the former has the problem of increasing the number of bins in the collating device, and the latter has the problem of wasting blank paper and requiring time and effort to remove the blank paper after copying is completed.

〔the purpose〕

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide a collation device that can clearly distinguish between interrupted copies.

In the normal clear mode, the receiving guide 7 is operated to the position shown by the solid line by the action of a shaft 8 driven by a solenoid (not shown). Therefore, in the clear mode, the copy paper 3 is transferred to the tray 10 by the paper ejection roller pair 9. is discharged.

When the sorter 2 is in the sorting mode and the stacking mode, the receiving guide 7 is operated as shown in broken lines in the figure, so that the copy sheet 3 is moved along the upper guide plate 11 and the lower guide plate 12 by the diagonal rollers. The sheet is conveyed in 13 directions, and is further conveyed to a pair of intermediate rollers 15 along with a positioning member to be described later by the diagonal roller 13 and brake member 14 .

Reference numeral 62 denotes a number memory for storing number data entered using the numeric keypad 37; 63, a document change key attached to the sorter 2 and used to copy another document without changing the number and mode; 64 is a solenoid drive circuit for driving the solenoid 26, and 65 is a flip-flop for storing an operating signal to the solenoid drive circuit 64.

(9) Sort key 31, stack key 32 on operation panel 30,
Interrupt key 33, stop key 34, print key 35,
Outputs from the clear key 36 and numeric keypad 37 are applied to the copying machine control circuit 50, and display data is sent from the copying machine control circuit 50 to the number-of-copies display 38, number display 39, and display 4o, respectively. It is being output. Further, the copying machine control circuit 50 and the comparison calculation circuit 51 exchange various data with each other.

With the above configuration, when an operator wants to make a copy in sort mode, he first places the original on the document table (not shown) of the copier, turns on the sort key 31 to select the sort mode, and then operates the numeric keypad 37 to make copies. After setting the number of copies, the print key 35 is pressed to start the copying operation of the copying machine 1. Accordingly, the copying machine control circuit 50 first operates the drive circuit 58 to drive each roller of the sorter 2 and moves the receiving guide 7 to the position shown by the broken line in FIG.

Therefore, the copy paper (10) discharged from the copying machine 1 3 is conveyed toward the collation section S as described above.

At this time, first, the first copy paper 3 is detected by the paper acceptance detector 5.
The count value of the paper acceptance counter 53 becomes 1 at the time when the paper is detected.
As a result, the comparison calculation circuit 51 controls the deflection claw drive circuit 60 to set the deflection claw 1 corresponding to the first stage bin 19.
Activate 8. As a result, the first sheet of copy paper 3 conveyed to the collating section S is discharged into the bin 19 in the first stage. Then, when the first copy sheet 3 is discharged into the first bin 19, the paper trailing edge detection circuit 54 outputs a detection signal, and the count content of the discharge paper counter 57 is incremented.

Thereafter, each time the copy sheets 3 are sequentially carried into the sorter 2, the count of the sheet receiving counter 53 increments, thereby corresponding to the bins 19 of the second stage, third stage, . . . . The deflection claws 18 are operated in sequence, and the second stage, third stage, etc.
At the same time as the copy sheets 3 are discharged into the respective bins 19, the count of the discharge paper counter 57 sequentially increments.

On the other hand, the comparison calculation circuit 51 compares the contents of the number memory 62 and the count contents of the ejected paper counter 57 at any time. Then, when the count of the set number memory 62 and the count of the ejected paper counter 57 match when the set number of copy sheets 3 are ejected into the bin 19, the sorting operation is ended.

Now, when the operator turns on the interrupt key 33 in order to copy another document during the above-mentioned sort copying, the AND circuit 66 becomes operational because the paper detector 22 in the bin is detecting paper at this time. Therefore, the ON signal of the interrupt key 33 is applied to the flip-flop 65 via the OR circuit 67 and the AND circuit 66, thereby setting the 7-lip flip-flop 65 and causing the solenoid drive circuit 64 to turn on the solenoid 26. As a result, the positioning member 23 described above moves in the manner shown by the dashed line in FIG.

Therefore, if the operator then sets the document to be copied on the document table, sets the number and mode, and then turns on the print key 35, the copy sheet 3 obtained at this time will be transferred to the sorter 2 at position E in FIG. The copy is held between the pair of intermediate rollers 15, and the copy can be distinguished from the pre-interrupt copy because its position when ejected to the bin 19 is different from that of the pre-interrupt copy.

Then, when the interrupt copy mode is reset, the copying machine control circuit 50 resets the flip-flop 65;
The solenoid 26 is turned off, the positioning member 23 is returned to its original position, and the copying operation before the interruption can be continued.

Further, when attempting to copy another document in the same copy mode and setting number as the first copy, the document change key 63 described above is turned on.

In this case as well, the solenoid 26 is turned on in the same way as when the interrupt key 33 is turned on, and the position at which copies are discharged into the bin 19 is changed.

Furthermore, if the numeric keypad 37 is operated again while printing continues and the number changed or the mode is changed, in either case an attempt is made to copy a document other than the one currently being copied. Therefore, in such a case (13), the combined copier control circuit 50 sets the logic level of the signal SD to rHJ.
and set flip-flop 65, solenoid 2
Turn on 6.

In the above-described embodiment, a diagonal roller, a brake member, a positioning member, a spring, a solenoid, etc. are used as means for changing the discharge position of the copy paper in the bin.
The configuration of such means is not limited to this.

〔effect〕

As explained above, according to the present invention, the ejection positions of the interrupt copy and the pre-interrupt copy in the bin are changed.
These copies can be clearly distinguished.
