The same field data is transmitted and received twice within one serial communication, and the data is compared. The data is determined, and next time, another field data is transmitted and received twice in the same way. If the received data is not determined due to some error occurring during the process, the same field data is transmitted and received in the same way next time.

A serial communication control flowchart is shown below in FIG. 7-1, and the operation will be explained below according to this flowchart.

After the power is turned on, the sorter 1 control microcontroller initializes the RAM, initializes the input/output board, and then sequentially executes operation sequence control, serial communication error check, and real communication data store, and receives 5REQI input from the copying device control microcontroller. Wait for (steps 1 to 4)
).

Furthermore, a timer interrupt routine is activated at predetermined intervals by the internal timer 7 interrupt of the microcomputer.

In the timer interrupt routine, the contents of the input port of the microcontroller (various sensor input states, etc.) are stored in the input port buffer provided in RAM, and the contents of the output port provided in RAM (various load drive information, etc.) are stored. Output to the output port of the microcontroller (Step 1)
51 to 152), the copying machine control microcomputer sends a 5REQL signal to the sorter 1 control microcomputer at the start of serial communication. When the sorter 1 control microcomputer receives the S REQ I signal, it immediately generates an internal interrupt and executes the 5 REQ I interrupt routine. In the 5REQI interrupt routine, the data reception interrupt and data reception are enabled, and the 5ACKI signal is sent to the copying machine control microcomputer (steps 5 to 9). When the copying machine control microcomputer receives the 5ACK signal, the first The transmission data is sent to the sorter 1 control microcomputer. The sorter 1 control microcomputer: i4When the first data is received, it immediately generates an internal interrupt and executes the data reception 474, ■ routine (Figure 7-2.7-3).

In the data reception interrupt routine, after determining whether there is a parity error or not, and whether or not the received data is an error code, if the received data is normal, the receiver G37-ter is temporarily stored in the heliphi register provided in the RAM. , and set the same field data as the received data in the transmit register.

If the received data is abnormal, count the inter-main unit communication error counter provided in the RAM, set the error hood in the transmission register, enable the data transmission interrupt and data transmission, and end the interrupt routine ( In steps 15 to 24), the sorter 1 control microcomputer executes a transmission interrupt routine (FIG. 7-4) when the first data transmission is completed. In the data transmission interrupt routine, when the first transmission is completed, the data reception interrupt and data reception are enabled, and the transmission interrupt routine is terminated (steps 48 to 51). When first transmission data is received from the sorter 1 control microcomputer, an error check is performed, and if there is no error, the same data as the first transmission data is transmitted to the sorter 1 control microcomputer as second transmission data. When the sorter 1 control microcomputer receives the second data, it immediately generates an internal interrupt and executes a data reception interrupt routine.

The data reception interrupt routine checks whether there is a parity error or not.
After determining whether the received data is an error code and whether it is equal to the first data.

If the received data is normal, store the received data in the receive buffer provided in RAM, set the same data as the first transmitted data in the transmit register as the second transmitted data, and if the received data If it is abnormal, set an error code in the transmission register, enable data transmission interrupt and data transmission, and end the reception interrupt routine (steps 15, 16, 25 to 32).
.

When the second data transmission is completed, the sorter 1 control microcomputer executes a data transmission interrupt routine. In the data transmission interrupt routine, when the second transmission 411m is completed, the 1 main unit reception data processing flag is set and the 1 main unit communication error counter is decreased.

The REQ2 signal is turned on to end the data transmission interrupt routine.

If the sorter 2 is not connected, serial communication with the copying machine control microcomputer is performed again.

Set the sorter 2 communication error counter to 0FFH and 5REQ
The I interrupt is enabled and the data transmission interrupt routine is ended (steps 48.49.52-60).

The sorter 2 control microcontroller is the sorter 1 control microcontroller/5
Upon receiving the REQ2 signal, it immediately becomes ready to receive data and turns on the 5ACK2 signal. When the sorter 1 control microcomputer receives the 5ACK2 signal, it generates an internal interrupt and
, executes the ACK 2 interrupt routine (Figure 7-1). In the 5ACK2 interrupt routine, the field data to be transmitted is set in the transmit register, and the data transmit interrupt,
Enabling data transmission (steps 10 to 1)
4) When the sorter 1 control microcomputer completes the first data transmission, it immediately executes a data transmission interrupt (Fig. 7-4).

In the data transmission interrupt, the data reception interrupt and data reception are enabled and the process ends (steps 48, 49, 52).
．． 61) When the sorter 2 control microcomputer receives the first data, it performs an error check, and if there is no error, it sends the same field data to the sorter 1 control microcomputer.

When the sorter 1 control microcomputer receives the first data, it generates an internal interrupt and executes a data reception interrupt. In the data reception interrupt routine, after determining whether there is a parity error and whether or not the received data is an error code, if the received data is normal, the received data is temporarily stored in a verify register provided in the RAM, and then transmitted. 1st in register
The same data as in "Time 1" is set, data transmission interrupt and data transmission are enabled, and the interrupt routine ends. If the received data is abnormal, count the communication error count between the two sorters provided in the RAM, and
Turn off the REQ2 signal and prepare for the first serial communication, 5
The REQI interrupt is enabled and the process ends (steps 33 to 38, 46 and 47).

As soon as the sorter 1 control microcomputer finishes the second data transmission, it generates an internal interrupt and executes the data transmission interrupt routine. In the data transmission interrupt routine, the data reception interrupt is enabled and the interrupt routine is ended (steps 48, 49, 52, and 61).

When the sorter 2 control microcomputer receives the second data, it performs an error check, and if there is no error, it transmits the same data as the first transmission data to the sorter 1 control microcomputer.

When the sorter 1 control microcomputer receives the fpJz-th data, it generates an internal interrupt and executes a data reception interrupt. The data reception interrupt routine checks whether there is a parity error or not.
After determining whether the i data is an error code or not, and whether it is the same as the first data, if the received data is normal, the received data is stored in the receive buffer provided in the RAM, and the sorter 2 receives the data. Set flag processing flag,
Reduce the sorter 2 communication counter, turn off the 5REQ2 signal, terminate serial communication with the saw 92, and prepare for the next serial communication with the copying machine control microcomputer.
Enable the EQ1 interrupt and end the interrupt routine. If the received data is abnormal, count the sorter 2 communication error counter, terminate any serial communication with the sorter 2, and enable the Monae S REQ L interrupt for the next serial communication with the copying machine control microcomputer. , the interrupt routine ends (steps 39-47).

Furthermore, the communication error check and egg routine are used in the MAIN routine to check whether the communication has ended within the set time, whether there is a communication error, and whether the counter has finished counting (communication abnormality) (step 3). In the communication error check, it is first determined whether the 5REQI signal has been received from the copying machine II microcontroller within a predetermined time, and if it has been received within a predetermined time, it is determined whether the serial communication has been completed within the set time. Move on to the step of determining.

If it is not received within a predetermined time, the inter-body communication error counter is counted, and serial communication with the sorter 2 control microcomputer is performed.

First, it is determined whether or not sorter 2 is connected, and if it is, the 5ACK2 interrupt is enabled in order to perform serial communication with the sorter 2 control microcomputer.
Turn on the REQ2 signal. If sorter 2 is not connected, set sorter 2 communication error counter 2 to 0FFH and send 5REQ in preparation for the next serial communication with the copying machine control microcomputer.
Enable I interrupt. If the serial communication has not finished within the set time, first disable data transmission/reception interrupts, first determine whether the communication is with the copying machine control microcomputer, and if so, first send the 5ACKI signal. It is turned off, the communication error counter between two main units is counted, and then it is determined whether the sorter 2 is connected. If sorter 2 is connected, is it a sorter? To perform serial communication with the control microcomputer, enable the 5ACK2 interrupt and turn on the 5REQ2 signal. If the sorter 2 is not connected, the sorter 2 communication error counter is set to 0FFH, and the 5REQI interrupt is enabled in preparation for the next serial communication with the copying machine control microcomputer. If serial communication is in progress with the sorter 2 control microcomputer, turn off the 5REQ2 signal, count the sorter 2 communication error counter, and enable the 5R EQI interrupt in preparation for the next serial communication with the copying machine control microcomputer. (step 114~
126). Next, check the communication error counter. If the inter-main unit communication error counter has finished counting (OF
FH), it is determined that the serial communication with the copying machine control microcomputer is in an abnormal state, and the inter-machine communication normal display is turned off. Similarly, if the sorter 2 communication error counter has finished counting (OFFH), it is determined that the serial communication with the sorter 2 control microcomputer is in an abnormal state, and the sorter 2 communication error counter is turned off (step 127 ~
132).

Furthermore, the data received through serial communication is processed by a serial communication data store routine within the MAIN routine (step 4), the details of which are shown in FIGS. 7-5 to 7-8. If the main body received data processing flag is set, the flag is first reset and the field designation of the received data is determined. In the case of the 1st and 2nd fields, the received data is stored in the receiving data area provided in the RAM.In the case of the 3rd field, the received data is stored in the received data area provided in the RAM. If the data is copy setting number data, the lower 4 bits of the copy setting number data consisting of 12 bits are updated.

If not, update the size data. In the case of the fourth field, the received data is stored in the reception data area provided in the RAM, and if the data sent is copy setting number data, the middle 4 bits of the copy setting number data consisting of 12 bits are stored. Update. In the case of the fifth field, the received data is stored in the reception data area provided in the RAM, and if the sent data is copy setting number data, the upper 4 bits of the copy setting number data consisting of 12 bits are stored. Update. In the case of the 'jPJs field, the received data is stored in the received data area provided in the RAM, and the lower 4 bits of the RAM address consisting of 8 bits are updated. In the case of the seventh field, the received data is stored in the received data area provided in the RAM, the 4 bits of the E position of the RAM address consisting of 8 bits are updated, and the process ends (steps 62 to 76). The RAM address sent through communication is determined in advance as the RAM address on the sorter 1 control microcomputer side that can be read by the copying machine (in this example, 0FFOO).
H-OFFFFH (256 bytes) The lower 8 bits of the 16-bit address are set on the copying machine side and transmitted along with the serial data. Sorter 1. The same applies to sorter 2 (steps 62 to 76).

If the sorter 2 received data processing flag is set,
Reset the flag and determine the field designation of the received data. In the case of the 1st and 2nd fields, the received data is stored in the received data area provided in the RAM. In the case of the third field, the received data is stored in the received data area provided in the RAM, and if the sent data is total bin number data, the lower 4 bits of the total bin number data consisting of 12 bits are updated. , otherwise the upper 4 bits of the sorter storage sheet count data consisting of 12 bits are updated. Fourth

Update the upper 4 bits of the total bin number data, otherwise update the upper 4 bits of the sorter storage number data consisting of 2 bits.
Update bits.

In the case of the sixth field, the received data is stored in the received data area provided in the RAM, and the lower 4 bits of the RAM data consisting of 8 bits are updated. 7th phi-
In the case of a field, the received data is stored in the received data area provided in the RAM, and the upper 4 bits of the RAM data consisting of 8 bits are updated. The total number of bins data mentioned here is data indicating the number of bins that can be sorted by each sorter. In this embodiment, the number of sortable bins 25 is sent from sorter 2 to sorter l, and sorter 1 Add 25 f function bins.

Send the number of sortable bins, 50, to the copy Jjc location.

However, sorter 1. If communication between sorter 2 is abnormal, sorter 1
ignores the number of sortable bins 25 of sorter 2 and sends sorter 1's own sortable bins 1125 to the copying machine. Further, data on the number of sheets stored in the sorter is stored in the backup area of the RAM and on the hour), and a REQ signal is transmitted to the sorter 1.

When sorter 1 receives the REQ signal, it transmits the REQ signal to sorter 2. When the sorter 2 receives the REQ signal from the sorter 1 (J), it sends the number data stored in the sorter 2 up to that point to the sorter 1, and the sorter 1 adds the number of sheets stored in the sorter 1 itself to the number data. and send it to the copying machine.

Therefore, the copying apparatus can grasp the number of sheets stored in the sorter via serial communication.

Therefore, even if the power of the sorter is turned off for JAM processing, the number of sheets stored in the sorter up to the time immediately before the JAMfi generation can be known, so that the copying apparatus can correct the number of copies remaining after the JAM. In addition, there is bin position data as other data stored in the backup area of the RAM. R.A.
By storing the bin position data in the backup area of M, the bin position will not be cleared even if the power is turned off.Therefore, since the bin position data is backed up, the bin can be moved immediately when moving to the home position. can. The above-mentioned RAM data is 8-bit data designated by the RAM address transmitted from the copying machine to the sorter 1 and from the sorter 1 to the sorter 2.

RA from copying machine to sorter 1 and from sorter 1 to sorter 2
By transmitting the M address, the 8-bit data designated by the RAM address is transmitted from sorter 1 to the copying machine and from sorter 2 to sorter I. By doing so, the copying machine is transferred to sorter 1. Sorter 1 can read the RAM contents of sorter 2.

Next, the display output/key manual routine (Figure i7-1o) in the copying machine control device microcomputer will be explained. First, if the copying device is in the process of copying, it checks to see if the copy stop key is pressed, and if it is, it stops the copying operation, otherwise it continues the copying operation without accepting any other keys. Desired display output/
Ending the key manual routine (steps 133-135)

33.136. L37), if the reset key is pressed, the number of sheets display 1 and the RAM address display 00 are output to the display section. If the set number clear rod is pressed, the number display 1 is output to the display section.

If the numeric keypad is pressed, input the set number of sheets and output it to the number display section (steps 133, 136, 13).
8 to 138), if the prisoner key is pressed, the next numeric keypad is judged to be a RAM address input, and the Te/key setting value is output to the display as a RAM address input.If the Figure 9 key is pressed again, it is a RAM address input. is output and sent to sorter 1 as the 6th data. The RAM address input into the seventh field is set, and the received data from the sorter 1 is set in the sixth field. The RAM data of the seventh field is output to the RAM data display section (steps 144 to 150).

Next, the conveyance motor control routine will be explained. In the transport motor control routine (FIGS. 7-11), the transport speed is varied by driving the transport motor of the sorter in pulses.

When operating or stopping the sorter transport motor 2,
Start this routine. First, the pulse output is turned off, and it is determined whether to operate or stop the transport motor 2. If the transport motor 2 is to be stopped, the transport motor control routine is immediately terminated.

To operate the transport motor 2, first set the pulse cycle to the internal timer of the microcomputer. Next, set the pulse low level time to the internal timer of the other microcomputer according to the value set by the transport speed setting volume S. death,
Turn on pulse output. Then, the microcontroller output terminal outputs a low level for the pulse low level time set from the start of the pulse, and then outputs a high level for the difference of the low level time from the pulse period. This operation continues until the pulse output is turned off (steps 153 to 158).

Control signals are transmitted and received through the serial communication described above to operate the sorter. Below is section 8 regarding its operation.
This will be described with reference to Figures-1 to 9-2. The sorter operation mode is non-sort mode.

There is a sort mode (reverse sort mode).

1. Non-sort mode (2 originals, 3 copies) (Reference M8-L, Figure 8-2) When the Cobby key on the display/operation section 17 of the copying device 16 is pressed, the set number of copies data (3 copies) is displayed. The operation mode (non-sort mode) is sent from the copying device 16 to the sorter 119 via serial communication, and then the BCR, 5STRT signals are sent. The sorter 119 that receives the BCR signal moves the bins to the non-sort home position.

When the bin movement is completed, the sorter 119 sends the copying device 16 a 5
Send STBY signal. When the copying machine 2116 receives the 5STBY signal from the sorter 119, it shifts the BCR signal to an off-record copy operation, and since the BCR signal is turned off, the sorter 119 switches the paper section direction plate 3 to the non-sort side and operates the transport motor 2. let The sheet is in the output stage of the copying machine 18
While passing through, an FDP signal is sent to the sorter 119. Sorter 1
19 starts a JAM timer from the time this FDP signal changes from on to off, and monitors the arrival of the non-sort paper sensor 13 of the sorter 119. The sorter 119 does not move the bins up even when sheets are fed.

After copying and discharging the set number of sheets, the copying device 16 sets the next document from the automatic document feeder 21 at the exposure position of the platen 17, sends the number of sheets data and operation mode (non-sort mode) to the sorter 119, and then outputs BCR, 5STRT. send a signal.

When the sorter 119 receives the BCR signal from the copying device 16, it turns off the 5STBY signal, and the previous original sheet is transferred to the sorter 1.
The 0SRT signal is sent to the copying machine 2116 until the copying machine 2116 is completely delivered. At this time, when the last copied sheet of the previous original is stored in the sorter 119, the 05RT signal is sent off to 5STB.
Turn on the Y signal. When the copying device 16 receives the 5STBY signal from the sorter 119, it turns off the BCR signal and starts copying onto the sheet that was previously fed. Copying device 16
When the copy operation is finished, the original is ejected to the tray and the 5ST
After turning off the RT signal and confirming that the 5STRT signal is off, the sorter 119 turns off the 5STBY signal to the copying device 16 after the third sheet has passed the non-sort paper sensor 13, turns off the transport motor 2, and switches the paper section direction plate 3 to the sorting side. Switch to.

2) Note mode (reverse sort mode) (2 originals, 30 copies) (Refer to Figure 9-1.9-2) When the copy key on the display/operation section 17 of the copying device 16 is pressed, the copy setting number data is displayed. (30 sheets) and the operation mode (note mode) are sent from the copying device 16 to the sorter 119 via serial communication, and then BCR, 5STRT4.4
The number will be sent. Based on the BCR signal, the sorter 119 transfers the number data of 5 sheets exceeding the number of sortable sheets (25 sheets) to the sorter 220.
and then send the BCR and 5STRT signals to the sorter 220.
send to BcR (Sorter 119 which received the s number. Sorter 2
20 each move a bin to the sort home position (
Refer to Figure 9-1 1)) When the bin movement of the sorter 220 is completed, a 5STBY signal is sent to the sorter 119. The sorter 119 completes the bin movement, and the 5ST from the sorter 220
Upon receiving the BY signal, it sends a 5STBY signal to the copying device 16. When the copying device 16 receives the 5STBY signal from the sorter 119, it turns off the BCR signal and starts copying, and when the BCR signal turns off, the sorter 119 operates the transport motor 2 of the sorter 1 to move the 1-sheet deflection plate 3. Switch to sorting side. While the sheet is passing through the copy machine paper sensor 18, an FDP signal is sent to the sorter 119. The sorter 119 starts a JAM timer from the time this FDP signal changes from on to off, and monitors the arrival of the sheet to the sorting sensor 14 of the sorter 119. Each time a sheet passes through the sorting paper sensor 14, the bin motor 5 is operated to raise the bin one by one until 25 sheets arrive at the sorting paper sensor 14 of the sorter 119 (see Figure 9-1) Sorter 1
After storing 25 sheets in the sorter 19, the sorter 119 moves to the bridge 10 and turns off the BCR signal to the sorter 220, thereby operating the transport motor 2 of the sorter 220. The 26th sheet from copying device 16 is sent to sorter 220 via this bridge 10. At the same time, by sending an FDP signal from sorter 119 to sorter 220, sorter 220 activates a JAM timer in order to detect a JAM between sorter 119 and sorter 220 (see FIG. 9-1, qi).

The sorter 220 operates the bin motor 5 every time a sheet passes the sorting paper sensor 14 from the 26th sheet to the 29th sheet, and raises the bin by 1 bin (see FIG. 44 of 9-1). When the bin passes, the number data of 5 sheets sent from the sorter 119 and the number of 5 sheets sorted by the sorter 220 match, so loading the bin is prohibited. Copying device 1
6, after ejecting the set number of copies, set the next original from the automatic document feeder 21, and similarly enter the number of sheets data and operation mode (
After sending the sort mode) to the sorter 119, BCR,5
Send STRT signal. The sorter 119 is SST B
Y (At the same time as No. 3 is turned off, the 05RT signal is sent to the copying device 16 until the sheets of the previous original are completely delivered to the sorter 220. At this time, when the last sheet of the previous original passes through the sorter 119, it is classified surplus to the sorter 220. After sending the sheet count data and operation mode (sort mode), BCR, 5S
Send TRT signal.

The sorter 119 checks that the number of sheets sent previously matches the set number of copies, and that the bridge 10 has a bin position.
Since the STRT signals are continuous, after data on the number of classified surplus sheets is transmitted to the sorter 220, the operation mode is set to reverse sort mode. The sorter 220 transmits the 5STBY signal and the 05RT signal to the sorter 119 until the last sheet of the previous document is stored. When the last sheet is stored, the bin position (fifth bin) of the sorter 220, the number of sheets of the next original (5 sheets), and the number of stored sheets of the previous original (5 sheets) match,
And because the 5STRT signals are continuous.

Set the operation mode to reverse sort mode, turn off the 03RT signal, and turn off the 5STBY and RS RT double signal sorter 119
send to Sorter 119 receives 5STBY from sorter 220
After receiving the signal and confirming that the reverse sort mode of the sorter 119 has been established, 5STBY and R5 are sent to the copying device 16.
Send RT signal. The copying device 16 starts copying onto the paper previously fed, and first starts sorting from the sorter 220. The sorter 220 lowers each sheet one bin at a time, contrary to the sort mode (see section 9-1).
Figure 1 @).

When the copying device 16 finishes copying the surplus number of sheets (5 sheets) and receives the R5RT signal from the sorter 119, the sorting passes through the bridge 10 and is stored in the sorter 220, and the sorter 119 moves from the bridge to the 25 bin. The copying operation is stopped for a certain period of time longer than the moving time, and the fifth sheet is completely sent to the sorter 119. Sorter 119
When the fifth sheet is sent to bridge 10, sorter 2
Send BCR and 5STRT signals to 20. When the sorter 220 receives the BCR signal, it turns on the 05RT signal and turns off the 5STBY signal until the sheets on the bridge 10 are stored. Since the sorter 220 is in the reverse sort mode, when it receives the BCR signal, it switches the operation mode to the sort mode, and since the bin is at the sort home position, when the fifth sheet is stored, the O5RT double signal is reset, and the 5ST
A BY signal is sent to the sorter 119. After the sorter 119 sends the BCR and 5STRT signals to the sorter 220, it prohibits bin movement until the 0SRT signal from the sorter 220 is turned off. After the sorter 220 confirms that the 05RT signal is turned off, the sorter 119 moves to the 25th bin, operates the bin motor 5 every time the 6th to 30th sheets pass the sorted paper sensor 14, and then moves to the 1st bin. Sort the sheets while lowering the bins (see Figure 9-1 ■, ■)
)6 After copying is completed, the copying device 16 discharges the original onto the tray of the automatic document feeder 21, and then turns off the 5STRT signal to the sorter 119. After the 30th sheet passes through the sort paper sensor 14, the sorter 119 sends it to the copying device 16 by R5RT and 5STBY.
Turn off the signal and stop the transport motor 2.

3. Collate mode (2 originals, 3 copies) (Reference section 10-1.10-2) When the copy key on the display/operation section 17 of the copying device 16 is pressed, the copy setting number data (3 sheets) and The operation mode (collate mode) is sent from the copying device 16 to the sorter 119 via serial communication, and then the BCR, 5STRT signals are sent. Upon receiving the BCR signal, the sorter 119 moves the bins to the sort home position (see Figure 10-1 ■), and when the bin movement is completed, the sorter 119 moves the bins to the sorting home position.
Send 5STBY signal to 6.

When the copying device 16 receives the 5STBY signal from the sorter 119, it turns off the BCR signal and starts the copying operation again.
9 switches the paper damage direction plate 3 to the sorting side as the BCR signal is turned off, and operates the conveyance motor 2. While the sheet is passing through the copying device paper ejection sensor 18, the PDP is placed on the sorter 119.
send a signal. The sorter 119 starts a JAM timer from the time this FDP signal changes from on to off, and monitors the arrival of the sorted paper sensor 14 of the sorter 119.

Copy! After the set number of copies have been ejected, 116 sets the next original from the automatic document feeder 21 and sends the number of sheets and operation mode (collate mode) to the sorter 119.
SFT, 5STRT signals are sent.

When the sorter 119 receives the BSFT signal from the copying device 16, it turns off the 5STBY signal, and the sheet of the previous original is transferred to the sorter 1.
The 03RT@ number is sent to the copying device 16 until it is completely delivered on 19th. At this time, when the last sheet of the previous document is stored in the sorter 119, the 0SRT signal is turned off and the 5STBY signal is turned on. The copying device 16 is 5STBY from the sorter 119.
When it receives the signal, it turns off the BSFT signal and starts copying onto the sheet that was previously fed. Sorter 119 is BSF
After confirming that the T signal is off, raise the l bin (see @10-
1 (■), when the copying device 16 finishes the copying operation, it discharges the original to the tray of the automatic document feeder 21, and then
After confirming that the 5STRT signal is off, the sorter 119 turns off the 5STBY signal to the copying device 16 after the third sheet has passed the sorted paper sensor 14, and turns off the conveyance motor 2.

In this embodiment, a sorter is used as an example of the sheet processing apparatus, but the present invention is not limited to this; for example, an automatic document feeder, a stapler, a folding apparatus, etc. may be used.

Further, in this embodiment, a dedicated display is provided as a RAM address and data display section, but other display devices such as a number-of-sheets display may also be used.

Effects As described above, according to the present invention, sheets can be stored in the reverse order under predetermined conditions, so that sheets can be reliably classified and stored.
