Sort key 31, stack key 32 of operation panel 30,
Interrupt key 33, stop key 34, print key 35,
The outputs of the clear key 36 and numeric keypad 37 are applied to the copying machine control circuit 50, and the copying machine control circuit 50 sends display data to the copy number display 38, number display 39, and display 4o, respectively. is the output formula. Further, the copying machine control circuit 50 and the comparison calculation circuit 51 exchange various data with each other.

With the above setup, when the operator makes a copy in the sort mode, after placing the unfrozen original on the document table of the copying machine (not shown), turn on the sort key 31 to select all sort modes, and press the numeric keypad 37'ff: The user operates to set the number of copies and presses the print key 35 to start the copying operation of the copying machine 1. As a result, the copying machine control circuit 50 first operates the drive circuit 58 to drive each roller of the sorter 2, and also moves the receiving guide 7 to the position shown by the broken line in FIG.

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

At this time, first, the first sheet of value copying paper 3 is detected by the paper acceptance detector 5.
At the time when the paper receiving input/counter 53 is detected, the count value of the paper receiving input/counter 53 becomes 1, and this causes the comparison calculation circuit 51 to control the deflection claw drive circuit 60 to set the deflection claw 16 corresponding to the first stage bin 17. Activate. As a result, the first copy sheet 3 conveyed to the processing section S is discharged into the bin 17 in the first stage.

Then, when the first copy sheet 3 is discharged into the first bin 17, the sheet trailing edge detection circuit 54 outputs a detection signal, and the count content of the discharged sheet counter 57 is incremented.

Thereafter, each time the copy sheets 3 are sequentially conveyed to the sorter 2VC, the counting contents of the paper receiving counter 53 increments, and as a result, the deflection claws 16 corresponding to the bins 17 of the second stage, third stage, etc. are activated in sequence, the second stage, third stage, etc.
At the same time as the copy sheets 3 are ejected into the bin 17, the count of the ejected paper counter 57 sequentially increments.

On the other hand, the comparison arithmetic circuit 51 compares the contents of the number memory 62 and the counted contents of the ejected sheet counter 57 at any time. Then, when the count contents of the set number memory 62 and the discharge counter 57 match when the set number of copy sheets 3 are ejected into the bin 17, the data of the set number memory 62 is latched into the copy number memory 63. After setting, this copy number memory 63
The data of the maximum value memory 64 is compared with the data of the maximum value memory 64, and the larger value is written to the maximum value memory 64.
Update the value of 4. In this case (Jin), the data in the maximum value memory 64 is the initial reset value, that is, 0, since the copying of the first document has been completed, and therefore the data in the number-of-copies memory 63 is written to the maximum value memory 64. .

Copying in the sort mode is performed for the second, third, etc. document in sequence, and each time the copying for each document is completed, the number of copies of the document (i.e., the number of copies to be sorted) is changed to the same number of copies. Recorded in number memory 63'
(At the same time, it can be compared with the data in the maximum value memory 64, and the maximum value memory 64P can store the maximum value.

Therefore, when a series of sort mode copies are completed,
At this point, the maximum value memory 64 stores the maximum number of copies in this series of copies, that is, the number of used bins 17 (or the number of copies). Also, when copying is completed for each original, the maximum value memory 6
The data of No. 4 is compared to the copying machine IJ by the comparison calculation circuit 51.
By transmitting the data to the cooling circuit 50 and displaying it on the display 40, the operator can be informed of the number of months the bin 17 has been used.

Further, the comparison calculation circuit 51 generates data obtained by subtracting the value obtained by adding 1 to the data in the maximum value memory 64 from the total number of bins, that is, interrupt sortable copy number data DI%a=, and sends this to the input terminal of the multiplexer 65. Added to A. That is,
Data D is obtained by the following equation.

(D, )=(Da)−((Dm>+1), (
Db) is the value of data D, (Da) is the number of bins, (Dm
) is the value of the data in the maximum value memory 64.O As mentioned above, when copying in the sort mode for multiple original sets is being performed, when another operator sorts and copies all of the original sets, first , this operator presses the interrupt key 33 and the sort key 31. As a result, each of the outputs of the keys 31 and 33 becomes the logic level rHJK, so that the output terminal of the AND circuit 68 becomes the R-side signal rHJ. Therefore, the control terminal C1 of the multiplexer 65 is at the logic level rHJ9, which causes the multiplexer 65 to apply the data Dbt to its input terminal A.
This is output to the display device 66, and as a result, the number of copies that can be sorted by interruption is displayed on the display device 66.

When the operator selects the desired number of copies within the displayed value and inputs the desired number of copies using the numeric keypad 37, this input data is stored in the number memory 62 as described above.

] When the print key 35 is pressed after the original is set, the comparator circuit 51 operates the deflection claw 15' corresponding to the (Dm+2)th bin 17 to bring this bin 17 to the home position. Thereafter, in the same manner as described above, the j-th bin 17' (i-) is selected at l for which the value of the discharge paper counter 57 matches the value of the number memory 62.

Therefore, during the interruption sort copying, the copy sheets 3 can be collated into the last bin of the bins used for the copy before the interruption.

When interrupt sort copying is performed in this way, one empty bin will be located between the bin used before the interrupt and the register used at the time of interrupt sort copying, so both The division becomes clear.

Note that the same effect can be obtained even when the constant 1 in the second term ((Dm)+1) on the right side of the above equation is changed to another natural number. However, in that case, it is necessary to change the home position at the time of interrupt sorting as appropriate depending on the value of the above constant.

By the way, there are no copy sheets 3 in any of the bins 17 in the collating section S.
If there is no output, for example, when the operator removes all the copy sheets 3 from the bin 17 after sort copying is completed, the output of the bin paper detector 20 becomes the processing level "L", and the output of the inverter 69 becomes logic. As a result, the maximum value memory 64 is reset, and at the same time, the control terminal C2 of the multiplexer 65 becomes a logic level "H", so that the data in the number memory 52 in bin a, which is applied to the input terminal B of the multiplexer 650, is selected. and the total number of bins is displayed on the display device 6.

FIG. 5 shows another implementation v1 of the invention.

In this embodiment, paper detectors S1 to Sn are provided in each of the valley bins 17 to detect when the subject paper 3 is discharged into the bin. Therefore, as shown in FIG. Vessel SL~S
An OR circuit 71 that takes the logical interest of the output of n and an inverter 72 that inverts the output of this OR circuit 71 and applies it to the sH terminal C1 of the multiplexer 65 are added to the circuit shown in FIG. Paper detection circuit 20, maximum value memory 6

In the LC, since the detection values of the paper detectors 81 to S0 are all at the logic level rLJ, the output of the OR circuit 71 is at the logic level r.
Due to LJ, the fiber level of the control terminal C2 of the multiplexer 65 becomes λrHJ, and the data in the total number of bins memory 52 is selected by the multiplexer 65 and displayed on the display device 66.

In addition, in FIG. 5, the same parts as in FIG. 3 are omitted in this embodiment.

In any of the embodiments described above, if the number of copies input using the numeric keypad 37 exceeds the number of copies that can be sorted by interruption in the U-inclusive sort mode, the copying machine temporarily enters the one-money hold state. At the same time, the sorter confirmation display is displayed on the display 40 (
For example, messages such as "number of copies exceeded") all lines,
Alert the operator.

Note that in the above embodiment, one empty bin is placed between the bin used at the time of interrupt sorting and the bin used before the interrupt.
I try to put one, but this number can be set arbitrarily.

In addition, when the interrupt sort mode is set, the available bins are blinking and the interrupt note start bin is displayed by the LEDs (light emitting diodes) L+ to L that indicate the bins in use as shown in Figure 6. By displaying all the information, the operator's attention can be better drawn.

〔effect〕

As explained above, according to the present invention, the copy at the time of interrupt sorting is ejected from the bin located one place with the copy of interrupt i1], so the copy before the interrupt and the copy at the time of interrupt sorting. This has the effect of being able to reliably identify K.
