Indicates that it has been entered.

Next, regarding the handling of reservation data, see 70- in Figure 9-1.
Explain according to the chart. First, when the operating unit CPU is powered on, it is initialized and the memory display digits, etc. are cleared.

Next, there is enough time (several tens of m5) for the CPU to communicate.
ec), reads the data of the copying machine CPU and ADF'CPU, and checks the status of the presence or absence of originals in each row and copy 1i.
The operation unit CPU 80 determines the copy status from the cPU 81 . These control the lighting of the display.

Numeric keypad manual judgment From these initial modes, output "L" to the "O" bit of the rOPB port, collect the 8-bit status of the PA boat, and judge whether any bit has become "L". , is "L", it is assumed that there is a key-in, and the bit counter determines which bit is "L".

For example, when 3" is keyed in, the status signal of the PA boat becomes , and this status signal is taken into the 7 accumulator (Acc). If you shift to the right sequentially, it will start from the 0th time,
At the third time (counter value), the zero flag is set, and when the counter is "3", proceed to the following routine, check what digit it is on the display digit counter, and if the digit counter is not 1, the first digit is set. As the key input, the bit counter value “3” is input to the first digit display register 1 in the RAM 83.
is stored, the digit counter is incremented by 1, and the display data and digit data are output to the second display n87. In the above example, we described the judgment of numeric keys "θ~7", but the flow also shows the judgment of 8" and "9". In the same way, the human power of the numeric keypad is detected by setting the numeric keypad to .Also, in the case of two-digit input, the first numeric value keyed in is transferred to the display register for the second digit, and then the numeric keyed-in value is transferred to the first digit. is stored in the display register.In this example, input of two or more digits is prohibited.

The number of copies per copy Ni, the time Ts required for copying per sheet of the copying machine, which is preset based on the performance of the copying machine, the time T required for ejecting the original to the document table, including the moving time of the document table and the transfer of the document, etc. The processing time Ti for each reservation group is calculated and stored in each area.
Based on the data from 81, it is determined whether there is a remaining portion to be copied, and the processing time for the remaining portion is calculated.

When all of these calculations are completed, they are all added together to calculate the total time ΣT.

Next, the current time is determined by giving the clock IC the CLOCK address from the 0 controller PD board and reading the READ button.
Reading is performed by setting the lamp to H'', and the current time data is taken into the operating unit CPU (it is read out as ○ hours Δ minutes).

By adding ΣT to this current time, the end time of copying the reservation is calculated. (value of ◯ hours and minutes) This calculation result data is stored in the end time memory area for each stage, and is also transferred to the display section 87 to display the time in advance.

Next, the copying machine determines from the "Busy" signal whether or not the copying process is currently in progress from the inter-CPU interconnector mentioned above.
If not usy, the end time t+ − is selected from the reserved memory.
The smallest one of t4 (scheduled) is determined, those copy data blocks are placed on the communication data and transferred, the reservation 7 lag is cleared, the original routine is returned again, and the above-described operations are repeated. Thereafter, by removing the original that has been copied, the copy reservation data in the reproduction CPU section 80 is cleared.

On the other hand, the copying machine CPU 81 performs data transfer/copy processing as shown in chart 70 of FIG.

The copy 191cPU81 transfers its own data to the operating unit CPU80. The data is transmitted to each ADFCPU 82, and each data is received and stored in the RAM 84. Then, it is determined whether or not there is reservation data from the data sent from the operating unit CPU 80, and if not, the copying machine is initialized and data is transferred, so the same routine as described above is entered and waits until the reservation data arrives. If reservation data exists, Busy is set and new data is transmitted to the operation unit CPU 80. Then, it waits for a print signal from the λDFCPU 82 and enters the copying process, and performs the copying process while transferring data until the reserved number of copies is completed. When the number of remaining copies becomes O, Busy is reset and the process returns to the first routine.

In such a configuration, when the operator places a document on the multi-stage document tray and makes a program reservation as described above, the digital display window 161 changes from green to orange. The copying machine displays the time when the copy reserved by the current program will be completed based on the reservation program registered in the internal memory and the copy processing speed, for example, as shown in FIG. (10:25 in the figure) Regarding the subsequent document feeding relationship, the operation of the ADFCPU will be explained according to the chart in FIG. 8-70.

First, the transmission data from the operation unit CPU is received, and it is determined whether or not the number of columns is specified.When the specified number of columns, number of copies, etc. are sent to the ADFCPU, the presence or absence of originals on the tray is detected by 5W1B, and the copying machine is set to BUSY. If not, the feeding section enters the feeding print routine, but the feeding section has two modes A and B, and mode A, in which the document is fed from tray 2 and ejected to tray 13.
There is a mode B in which the paper is fed from the tray 13 and discharged to the tray 2. Each mode is summarized in the table below.

In chart 70 of FIG. 8, it is determined whether there is a document in tray 2 or tray 13, and mode A or B is set depending on which one is present.

Now, when the original is in tray 2, switch 18 is turned on.
In step S41, mode A is set and the process waits for a paper feed signal from the copying machine. When the paper feed signal is received, the rotary solenoid 24 is turned on, the state shown in Fig. 3a and Fig. 4.5 is reached, the paper feed motor 30 rotates in the direction of arrow 31, and the belt conveyance motor 12 turns ONL. It rotates 32 times,
Stopper 10 is also turned on. When the lowest document is sent out by the feed roller 4 and passes the pair of rollers 7 while being prevented from double feeding by the roller 6, the sensor 32 turns ON, the motor 30 turns OFF, and the feed roller 4 stops. However, the fed document is further fed by rollers 7 and belt 9.

When the sensor 11 is turned on, the motor 12 is turned off, the document is stopped at the stopper 10, a print signal is sent to the copying machine, and the copying end signal is waited for from the copying machine. When the end signal comes, the stopper 10 is turned off and the motor 12. The motor 35 is turned on, and the a-lars 14 and 15 rotate as indicated by the arrows in FIG. 1 to eject the original onto the tray 13. When the document passes the sensor 11, a timer is turned on for a time long enough to eject the entire document onto the tray 13, and when this timer is turned off, the belt conveyance motor 12.35 is turned on.
FF and wait for the next paper feed signal. At this point, switch 19 is turned on.
However, there is no change in operation in this state, and the process is repeated until there are no more documents on tray 2.

When all the originals on tray 2 are finished, one copy has been completed and the switch 18 is turned off.

When the final copy is made and the ejection switch 162 is turned ON-OFF, the $1 roll of interleaf paper 157 is transferred to the pair of nohinch rollers 1.
63, cut to an appropriate length by a cutter 164, and discharged by a roller 165 to be placed on the final copy paper.

As a result, the second set of copies is sorted, and the ejection switch 62 is turned on and off depending on the cut slip sheet.
Then, the second copy operation routine begins. By turning on the switch 19, the mode is set to B (the motor rotation is set in the opposite direction from the six directions), the rotary solenoid 24 is set to 0FFL, the lever 20 is set to 20'', and the Sabaki roller 6 is pushed up by the cam slope 28. The belt 36 is made of an elastic belt and is stretchable.When a paper feed signal is received in this state, the rotary solenoid 34 becomes ONL as shown in Figure 2, and the paper feed motor 35 and belt conveyance motor 12 are turned on and the paper is fed. When the paper feed sensor 11 is turned ON and OFF (that is, the document passes the sensor), the stopper 10 moves to 6 after a certain period of time.
N, the belt conveyance motor 12 rotates in reverse. When the document turns on the sensor 11 again, the belt conveyance motor 12
is 0Fl, and the original stops at the stopper position. Send the print signal, and the motor is turned ONL by the print end signal.
The original is ejected onto the tray 2, the switch 19 is turned off, and the process is repeated until the original on the original tray 13 is exhausted, and the required number of copies, such as 3 and 4 copies, are further copied. When the required number of copies has been copied and the specified number of copies ni matches the number of copies to be copied no, it is determined whether no is an odd number or an even number. If it is an even number, the copying is completed. 1) Return to START and make the next specification. wait. On the other hand, if the number is odd, the stepping motor 46 is moved to the third position where the documents on the tray 13 are ejected all at once.The tray 2 stops moving and the solenoid 49
By turning on, the document pressure is released. Tray 13
The stepping motor 48 is rotated to move and stop at the third position, and the solenoid 53 is turned on to release it. Next, the motors 52, 35.12 are turned on, and the originals on the tray 13 are collectively collected on the tray 2. After moving to tray 2, the detection switch 7-18 on the tray
Turn on %v--52, 35, 12 to 0FEFl and the copy is complete.

Next, a second slip sheet 158 passes through a roller 166, is cut by a cutter 164, is sent out by a roller 165, and is placed on the copy to serve as a partition of the document collection. When the ejection switch 162 is turned ON and OFF for this interleaving sheet, copying operation for the next reserved document collection starts and the same routine is repeated thereafter.

In this embodiment, there are two types of slip sheets. The reason for this is that it is easy to understand if the colors and shapes differ for each number of copies or for each manuscript collection, and even for one type, it is possible to differentiate by changing the length, etc.

Further, in this embodiment, the copy ejection tray and slip sheets are used to distinguish between originals, but the conventional method of sorting using a sorter may be used.

In this case, the document feeding mode does not need to be circulation type.
When connecting a sorter, it is also possible to cancel the circulation type.

Further, in this embodiment, the number of document sheets, two sheets, and two copies is shown as an example of pre-printing, but it goes without saying that functions such as magnification, paper, etc. can also be added to the reservoir as a reservation function.

Effects of the Invention As detailed above, according to the present invention, a tray is provided between the document table and the tray serves both for feeding and ejecting the document, so that the document can be used cyclically and the copying process is improved. It is possible to increase the speed, and it is possible to sort multiple sets of manuscripts without the need for a large-scale sorter. Furthermore, since the operator can make a reservation for copying and is given advance notice of the copying end time, the operator has the advantage of not needing unnecessary waiting time.
