The baud rate) is determined by the output from the internal clock of the microcomputer and the external clock oscillator OCR, and which one is used within the microcomputer is changed by setting the baud rate changeover switch BS (Figure i3-1). Therefore, asynchronous serial communication can be selectively performed using a plurality of baud rates. Note that the baud rate setting must be the same on the transmitting side and the receiving side in acyclic serial communication.

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 manner the first time.

5-1, 5-2, 6-1, and 6-2 show the structure of each field data and the control signal name, meaning, and role.

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

After turning on the power, the sorter 1 control microcomputer performs RAM initialization, input/output board initialization, etc., and then sequentially executes operation sequence control, serial communication error check, and serial communication data storage, while waiting for 5REQI input from the copying device control microcomputer. (Steps 1-4)
.

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

In the timer interrupt routine, the contents of the microcontroller's input ports (various sensor input statuses, etc.) are stored in the output ports provided in the RAM, and the contents of the output ports (various load drive statuses, etc.) provided in the RAM are stored. information, etc.) to the output port of the microcontroller (Step 1)
51 to 152), the copying machine control microcomputer sends a 5REQI 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 5ACK1 signal, the first 6. When the sorter 1 control microcomputer receives the first data, it sends the transmission data to the sorter 1 control microcomputer.

An internal interrupt is immediately generated and the data reception 44 interrupt routine (Figure 7-2.7-3) is executed.

In the data reception interrupt routine, parity errors
, After determining whether the received data is an error hood or not, if the received data is normal, the received 4i5 data is temporarily stored in the secure register provided in the RAM, and the same field data as the received data is stored in the transmitting register. Set.

If the received data is abnormal, it counts the inter-main unit communication error counter provided in the RAM, sets an error code in the transmission register, enables data transmission interrupts and data transmission, and ends 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 ended (steps 48 to 51). When the copying machine control microcomputer receives the first transmission data from the sorter 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 the 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.
Whether the received data is an error code or not.

After determining whether the received data is equal to the first data, if the received data is normal, the received data is stored in the receive buffer provided in the RAM and stored in the transmit register! Set the same data as the first transmission data in the transmission register as the second transmission data, and if the received data is abnormal,
An error code is set in the transmission register, data transmission interrupt and data transmission are enabled, and the reception interrupt routine is ended (steps 15 and 16, 25-32).

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

5Turn off the ACKI signal. Furthermore, if sorter 2 is connected, enable the 5ACK2 interrupt to perform serial communication with the sorter 2 control microcontroller, and
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, so the sorter 2 communication error counter is set to 0FFH, the 5REQI interrupt is enabled, and the data transmission interrupt routine is ended (steps 48 and 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
Execute the ACK2 interrupt routine (Figure 7-1). 5A
In the CK2 interrupt routine, field data to be transmitted is set in the transmission register, and data transmission interrupt and data transmission are enabled (steps 10 to 14). When the sorter 1 control microcontroller 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 the first time is set, the data transmission interrupt and data transmission are enabled, and the interrupt routine ends.

If the reception (a data) is corrupted, 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 second 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, whether the received data is an error code, and whether it is the same as the first data, if the received data is normal, the received data is stored in the RAM. Store the received data on the sofa, set the sorter 2 received data flag processing flag, reduce the sorter 2 communication error counter, turn off the 5REQ2 signal, finish the serial communication δ of the sorter 2, and connect it to the next copying machine control microcomputer. In preparation for serial communication, 5REQ
1 interrupt is enabled and the interrupt routine ends. If the received data is abnormal, count the sorter 2 communication error counter, terminate any serial communication with the sorter 2, and enable the S REQ 1 interrupt in preparation for the next serial communication with the copying machine control microcomputer.
The interrupt routine ends (steps 39-47).

Furthermore, the communication error check routine in the MAIN routine checks whether the communication has ended within the set time and whether the communication error counter has finished counting (communication abnormal state) (Step 3) 0 Communication error check ° First, the 5R from the copying machine control microcomputer within a predetermined time.
It is determined whether or not the EQI signal has been received, and if the EQI signal has been received within a predetermined time, the process moves to a step of determining whether the serial communication has been completed within the set time.

If it is not received within a predetermined period of time, the 1-machine 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 the sorter 2 is not connected, set the inter-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, then determine whether the communication is with the copying machine control microcontroller, and if so, first send the 5ACKI signal. It is turned off, the communication error counter between the 5 main bodies is counted, and then it is determined whether the sorter 2 is connected. If the sorter 2 is connected, the 5ACK2 interrupt is enabled and the 5REQ2 signal is turned on in order to perform serial communication with the sorter 2 control microcomputer. 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), then 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 normal display is turned off (steps 127 to 1).

Furthermore, the data received by serial communication is
Processing is performed by the serial communication data store routine within the N routine (step 4). The details are 7-5~7-

The RAM7 dress sent is a copy in advance! Determine the RAM address on the sorter 1 control microcomputer side that can be read on the re a side (this example 0F
FOOH-OFFFFH (256 bytes) The lower 8 bits of the 16-bit address are set on the copying machine side and sent 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,

The total pin data mentioned here is data indicating the number of sortable bins for each sorter. In this embodiment, sorter 2 to sorter 1
The number of sortable bins, 25, is sent to .

Sorter 1 further adds 25 sortable bins.

Send the number of sortable bins, 50, to the copying machine.

However, if the communication between sorter L and sorter 2 is abnormal, sorter L
ignores the number of sortable bins of sorter 2, which is 25, and uses sorter 1g.
The number of sortable bins, 25, is sent 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, it transmits data on the number of sheets stored in the sorter 2 to the sorter 1 so far.

The sorter 1 adds the number of sheets stored in the sorter 1 itself to the sheet count data and transmits the result to the copying apparatus.

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 until the time the JAM occurs can be known, so 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. RAM
By storing the bin position data in the bank amplifier area, 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 quickly moved to its home position. The above-mentioned RAM data is 8-bit data designated by the RAM address transmitted from the copying machine to sorter 1 and from sorter 1 to 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 1. 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 (FIGS. 7-10) in the copying machine control device microcomputer will be explained. First, if the copying machine is in the process of copying, it checks to see if the copy stop key is pressed. If it is, it stops the copying operation. If not, it continues the copying operation without accepting any other keys. Display output/
Ending the key manual routine (steps 133-135)
), if the copy operation is not in progress, each key is checked. If the copy start key is pressed, the copy operation sequence is started, other key input is prohibited, and the display output/key input routine is ended. (Stop 133
．． 136, 137), if the reset key is pressed, the number of sheets will be displayed 1. Outputs RAM address display OO to the display section. If the set number clear key is pressed, 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 key is pressed, the next numeric keypad is judged to be a RAM address input, and the te/key 1 set value is stored in the RAM.
If the 0 figure key which is output to the display section as an atray input is pressed again, the RAM address input is output and the 6th data to be sent to the sorter 1 is output. Set the RAM address input in the 7th field, and set the received data from the sorter 1 in the 6th field. 7th
The RAM data of the 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, then 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 Sv. ,
Turn on pulse output. Then, the programmable rectangular wave output terminal of the microcontroller outputs a low level for the pulse low level time set from the pulse start, 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).

■, Non-sort mode (2 parts M3 & copy) (see Figure 8-1.8-2) When the copy key on the display command operation section 17 of the copying device 16 is pressed, the copy setting number data (3 sheets) and the operation mode are displayed. (//
mode) is sent from the copying device 16 to the sorter 119 via real 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 '16 receives the 5STBY signal from the sorter 119, it turns off the BCR signal and starts the copying operation, and at evening I L9, when the BCR signal is turned off, it switches the wind deflection plate 3 to the non-sorting side. ,
Operate the transport motor 2. While the sheet is passing through the copying device paper discharge processor 18, a PDP 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 yI up to the non-sort paper sensor 13 of the sorter 119. Sorter 1
19 does not raise the bottle to E even if a note is sent.

After ejecting the set number of copies, the copying device 16 automatically sets the next document from the document feeder 21 to the exposure position of the platen 717 and outputs the number of sheets and operation mode (non-sort mode).
After sending it to the sorter 119, the BCR and 5STRT signals are sent.

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 osRr@ number is sent to the copying device 16 until it is completely delivered to the copying machine 19. At this time, when the last copied sheet of the previous original is stored in the sorter 119, the 03RT signal is turned off and the 5STBY
Turn on the signal. The copying device 16 has sorters 119 to 5.
When it receives the STBY signal, it turns off the BCR signal and starts copying onto the sheet that was previously fed. When the copying device 16 completes the copying operation, it discharges the original onto the tray and processes it at 5STR.
After turning off the T signal and confirming that the 5STRT signal is off, the sorter 119 turns off the 5STBY signal to the copying device 16 after iMing the third non-sort paper sensor 13, turns off the transport motor 2, and sets the wind deflection plate 3 to the sorting side. Switch to.

2. Note mode F' (reverse sort mode) (2 copies of manuscript,
30 copies) (See! Figure 9-1.9-2 of 1st section) When the copy key on the display/operation section 17 of the copying device 6 is pressed, the copy setting number data (30 copies) and operation mode (sort mode) are displayed. ) is sent from the copying device 16 to the sorter 119 via the printer communication, and the ? &BCR,5STRT signals are sent. In response to the BCR signal, the sorter 119 sends the number data of 5 sheets exceeding the number of sortable sheets, 25, to the sorter 220, and then sends the BCR, 5STRT signal to the sorter 220. Sorter 119 that received the BCR signal. Sorter 220
move the bins to their respective sorting home locations (see Figure 9-1)). When the sorter 220 completes the bin movement, it sends a 5STBY signal to the sorter 119. Sorter 11
9, the bin movement is completed and 5STBY is sent from the sorter 220.
Upon receiving the signal, it sends a 5STBY signal to the copying device 16.

The copying device 16 turns off the sorter and moves on to the copying operation, and the sorter 119 operates the conveyance motor 2 of the sorter 1 as the BCR signal is turned off, and changes the wind deflection plate 3 to the sorting side. While the sheet is passing through the copying device paper discharge sensor 18, an FDP signal is sent to the sorter 119. The sorter 119 starts the JAM timer from the moment this FDP signal changes from on to off, and the sorting paper sensor 14 of the sorter 119
Monitor the arrival of sheets up to. 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). After storing 25 sheets, the sorter 119 moves to the bridge 10.
At the same time, by turning off the BCR signal to the sorter 220, the transport motor 2 of the sorter 220 is operated. The 26th sheet from copying machine 16 is sent to sorter 220 via bridge 10. At the same time, the sorter 220 activates a JAM timer in order to detect a JAM between the sorter 119 and the sorter 220 (see Figure 1 of the reference section 9-1).

The sorter 220 operates the bin motor b to raise the bin one by one each time the 266th to 299th sheets pass the sorted paper sensor 14 (see Figure 9-1, →)).
When the 300th sheet passes through the sorter 220, 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. After copying the set number of sheets and ejecting them, the copying device 16 sets the next document from the automatic document feeder JJt device 1, similarly sends the sheet number data and operation mode (sort mode) to the sorter 119, and then outputs the BC.
Send R,5STBY signal. Sorter 119 is 5STBY
At the same time as the signal is turned off, the previous original sheet is transferred to the sorter 220.
The 0SRT signal is sent to the copying device 16 until the copying machine 16 is completely loaded.

At this time, when the last sheet of the previous document passes through the sorter 119, data on the number of surplus sheets to be sorted and the operation mode (sort mode) are sent to the sorter 220, and then BCR, 5STBY
send a 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.
When the STBY signal is continuous, data on the number of surplus sheets to be sorted is sent to the sorter 220, and the operation mode is set to reverse sort mode. The sorter 220 turns off the 5STBY signal to the sorter 119 and transmits the 05RT signal until the last sheet of the previous g document is stored. When the last sheet is stored, the bin position (5th bin) of the sorter 220, the number of sheets of the next original (5 sheets), and the stored number of sheets of the previous original (5 sheets) match, and the 5STBY signal is continuous. .

The operation mode is set to reverse sort mode, the 05RT signal is turned off, and the 5STBY and R5RT signals are sent to the sorter 119. When the sorter 119 receives the 5STBY signal from the sorter 220, it confirms that the reverse sort mode of the sorter 119 has been established, and then sends the 5STBY and R3R signals to the copying device 16.

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 S5TRT signals to 20. Sorter 220
When it receives the BCR signal, it turns on the 0SRT signal and turns off the 5STBY signal until the sheet on the bridge 10 is stored. Since the sorter 220 is in reverse sort mode, the BCR
When the signal is received, the operation mode is switched to sort mode, and since the bin is at the sort home position, when the fifth sheet is stored, the 05RT signal is reset and the 5S
Send the TBY signal to the sorter 119. Sorter 119 (

After sending, bin movement is prohibited until the ○SRT signal from the sorter 220 is turned off. Sorter 119 is sorter 220
After confirming that the 03RT signal is turned off, the machine moves to the 25th bin, and each time a sheet from the 6th to the 300th passes the sorting paper sensor 14, the bin motor 5 is operated to lower the bin one by one. After the copying device 16 has finished copying, the document is ejected to the tray of the automatic document feeder 21, and then the document is sorted by the sorter 11.
Turn off the 5STBY signal to 9. Sorter 119 is 30
After passing the 0th sort paper upper flap 14, R to the copying device 16
3RT and 5STBY signals are turned off to stop the transport motor 2.

3. Collate mode (2 originals, 3 copies) (Reference section 1o-i, Figure 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 Is the operation mode (collate mode) copy? Sent from ttl16 to sorter 119 via serial communication, then BCR, 5STRT
A signal is sent. The sorter 119 that receives the BCR signal moves the bins to the sort home position (i.e.
1), the sorter 119 sends a 5STBY signal to the copying device 16 when the bin movement is completed.

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.

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 05RT signal is sent to the copying machine 16 until the copying machine 19 is completely loaded. At this time, when the last sheet of the previous document is stored in the sorter 119, the 03RT 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 @ sign, 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 it by one bin (reference path 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 invention is not limited to this.
h) It may be a document feeding device, a stapler, a folding device, etc.

Further, in this embodiment, a dedicated display is provided as a RAM address and data display section, but a display with functions such as a sheet number display may also be used.

Effects As described above, according to the present invention, the position data of the storage means is stored even when the power is turned off, so it is possible to quickly move the storage means to the reference position, etc.
