DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to management of a copying operation in a recording apparatus such as a copying machine and a printer, and more particularly, to a copying apparatus such as a copying machine and a printer provided with an automatic document feeder having a document recirculation function. The present invention relates to a divided compiler discharge method having a function of coping with a situation where a copy job exceeding the capacity of an internal tray (compiler tray: DPX tray) for creating a double-sided copy occurs in a copying machine (hereinafter referred to as a copying machine).

[0002]

2. Description of the Related Art In recent copiers and the like, in order to meet various needs of users, an ADF (automatic document feeder) for automatically feeding a document onto a platen glass and a double-sided document are automatically fed. DADF (Duplex Automatic Document Feeder),
Or an additional device with a document handling function that automatically feeds or circulates documents, such as an RDH (recycled document handler) that automatically returns documents to the original feed state and automatically repeats document feeding. Has been deployed in the market. For the apparatus configuration and control method of this type of copying machine, see, for example,
No. 6269 discloses this.

[0003]

In a copier or the like equipped with a conventional RDH, a one-sided original (SIMP original) → one-sided copy (SIMP copy), two single-sided originals → one double-sided copy (DPX copy: SPX / D), two-sided originals → two-sided single-sided copy (D / S), and two-sided originals → two-sided copy (D / D) when executing copy jobs in various modes such as one-sided copy paper ( SIMP paper), first page copy paper from two-sided originals or two single-sided originals (S
IDE1 paper = front copy paper) / 2nd page copy paper (SIDE2 paper = back copy paper) is not conveyed simultaneously in the main body (hereinafter simply referred to as the main body) of a copier or the like, , Paper) are always discharged in the order of the process (job until one copy is completed: hereinafter referred to as pitch). In addition, original scanning (scanning) and feeding of copy paper are always performed for the effective pitch.

[0004] Therefore, the time required to execute the copying of one unit (unit job) designated by the operator increases, and the copier or the like cannot be operated efficiently. To solve the above problem, unit jobs are scheduled for jobs that are physically very complicated, and the pitches that make up the unit jobs are quasi-sequential flows on the management data. A method has been proposed that facilitates job management by managing the job as. In other words, the above-mentioned method is based on the execution unit of the copy specified by the user interface (all the jobs for creating the copy set by the operator: unit jobs)
Is managed as a batch of control data of a job (a job in the smallest unit: SIDE1: pitch job) until one copy can be taken (a job in a single document unit or a job in a single document: a part job) and a copy process. And changes the data of a predetermined pitch job at the time of recovery when the copying machine is stopped for some reason, thereby enabling an effective recovery process.

However, once a job is scheduled, it cannot be changed after the copy processing operation is started. Therefore, if the copy operation is started and copying is continued according to the scheduled unit job, sheets entering the DPX tray will not be changed. If the capacity of the DPX tray is exceeded (the number of sheets limited), the counter for counting the number of sheets entering the DPX tray over-counts and the operation of the main body of the copying machine or the like stops. When such a state occurs, the operator is forced to perform troublesome work for the recovery, and there is a problem that the efficiency of the copy work is reduced and the paper is wasted. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and in a mode in which the number of sheets exceeding the limit number of DPX trays is entered, one unit of job can be divided into a plurality of schedules at the time of scheduling, so that efficient copying can be performed. It is another object of the present invention to provide a divided job discharging method.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an automatic document feeder (15) having a document recirculation function, and a compiler which discharges a predetermined set of copied sheets in units of one set. and a paper output unit having a discharge function (22), the user interface (36)

[0007]

The job control means (320) schedules the divided compiler job specified by the user interface as a plurality of part jobs. The divided compiler discharge control means (3201) counts the maximum number of sheets accommodated in the internal tray of the copying apparatus, detects divided compiler discharge information of the part job having scan end data, generates a compiler discharge command, and issues a PITCH SKIP command. It is given to the control means (330) and the output control means (380). PITCH SKIP control means (33
0) stops scanning of the CHM document, and the output control means (380) releases stapling and executes compiler discharge. As a result, a bundle of copy sheets of a limited number (for example, 50 sheets) of the internal tray is ejected, and finally, the OUTPUT for the number of sheets set by the operator is output.
A copy (finished copy) is obtained.

[0008]

Hereinafter, the details of the divided job discharge will be described based on the above configuration. First, the job (JOB) is defined again as follows. -Unit job (UNIT JOB: All jobs that create a copy set by the operator in the unit specified by U / I)-Part job (PART JOB): Scheduled by the main system (SQMGR32) that constitutes the unit job A batch of jobs; in the collate mode, a job in a single document cycle; in the uncollate mode, a job in a single document (1 SIDE) unit; a pitch (process) job: a minimum unit job constituting a part job; one copy Job (Pitch → Feed → Scan → Exit) to complete (1SIDE)

FIG. 13 is an explanatory view of the sheet feeding path in the divided job mode. The sheet is fed from the upper tray 6-1, the middle tray 6-2, the lower tray 6-3, the manual tray 16, and the large capacity tray 17. The fed sheet is in OUTPUT direction A (discharged from the main body 1 toward the finisher 22).
And the DPX tray 11 direction B. OUT
The sheet in the PUT direction A is also divided into a top tray 221 direction C of the finisher 22 and a compiler tray 222 direction D. Eject split compiler (split COMPILE
REJECT) data management is as follows. 1. If the sheet conveyance direction is the compiler direction and there is no LAST information (EJECT information included in the schedule) in the final pitch information, the OUTPUT counter is incremented by 1 (if there is LAST information, the counter is set to 0). . 2. 5 pitch data included in the schedule
If 0, split into corresponding paper COMPILER EJEC
Mark T (bit). 3. OUTPUT is divided COMPILE
In the case of REJECT, the paper is ejected from the compiler. 4. If the SQMGR requires a split compiler, it does not perform the following processing while it needs it for the compiler eject operation.

FIGS. 14A and 14B are explanatory views of the pitch and the run length (R / L) on the photosensitive belt. FIG. 14A is a side view of the photosensitive belt, and FIG. 14B is a developed view of the photosensitive belt. is there. Referring to FIG. 3, an image area of one sheet obtained by scanning and exposing an image of a document on (b) in which the photosensitive belt is developed in (a) is defined as one frame, and an interval between adjacent frames is called a pitch. The data for the copy execution step operation corresponding to this pitch is referred to as pitch data (hereinafter simply referred to as pitch or PITCH). Each pitch is
The timing is determined based on a reference mark 40 provided on a predetermined portion of the photoreceptor belt 4. As the pitch data, execution data such as document scanning and paper feeding (paper feeding) as shown in FIG. Is scheduled. The number of frames required until the copying is completed is called R / L (run length).

FIG. 16 is a schematic diagram of the above-described job configuration. As shown in FIG. 16A, a group of a plurality of pitch data 100 is used as part job data 200, and a plurality of part jobs constitute unit job data 300. ing. The job configuration differs depending on the mode of the copying machine. In the collate mode as shown in (b), there are part jobs for each round of the original, and the number of pitches constituting each part job is equal to the number of originals. In the uncolate mode as shown in FIG. 3C, the part job is performed for each original (1 SI).
The number of pitches constituting each part job is equal to the set number.

The job configured as described above is controlled as follows. 1. The paper is always exited in the pitch order. If the EXIT of the succeeding pitch is completed before the EXIT of the preceding pitch is completed, it is assumed that the EXIT of the subsequent pitch is not completed on the data. It is assumed that the sheet EXIT of the succeeding pitch, which has already been completed, has been completed when the sheet EXIT of the preceding pitch has been completed. 2. Scan and paper EXI for all pitches
Assume that there is T. At the pitch where there is no scan or paper feed, the scan end and paper EXIT are simulated.
To produce With the above controls, unified job management is realized, resulting in man-hours (pitch numbers)
In addition, the memory can be reduced.

FIG. 17 is a signal configuration diagram exemplifying pitch data. Processing execution data such as sheet feeding (FEED) and scanning (SCAN) are stored with reference to the pitch start timing (pitch timing). . (Note that the pitch has an effective pitch and an invalid pitch, and the effective pitch has data indicating an actual copy operation, and the invalid pitch has data indicating that a copy operation is not performed.) The CHM issues a pitch cancel command when paper is not fed due to a jam or the like, and performs processing from the canceled pitch at the time of recovery.

FIG. 2 is a correlation diagram for explaining the flow of control information in FIG. 1, and FIG. 3 is an explanatory diagram of the contents of the control data (shown by dotted circles except for the dotted circles in the SQMGR in the figure). What is the condition of the paper--where the paper is-
-). First, the flow of control data in the configuration of FIG. 1 will be described with reference to FIG. This control data is b1 to b8
, And bit b1 is a compiler ejected according to the schedule (COMPILE EJE
CT), bit b2 is the end of the copy completion set (MAD
E SET LAST), bit b3 is the end of the set to be recovered (RECOVERY SET LAS).
T), bit b6 is the output of the divided compiler (DIVID
The bit b7 is a bit storage area for the end of the part job (PART JOB END), and is effective when the bit is "1". The reason why the divided compiler discharge area is provided in the bit b1 and the bit b6 is that the divided compiler discharge to be simulated is:
This is because the compiler discharge determined by the schedule of the bit b1 due to the recovery cannot be quickly turned on / off.

In FIG. 2, when paper is fed from the CHM under the control of the PITCH SKIP control means 330 (PAPER FEED), "PAPER FEED"

"R INFORMATION 2" is sent to the OUTPUT 38, and the OUTPUT 38 executes the compiler ejection by this command (B).

FIG. 4 is an explanatory diagram of the paper discharge mode of the finisher in FIG. 10, wherein 22 is a finisher, 221 is a top tray, 222 is a compiler tray, 223 is a stacker, and 224 is a gate. The sheet discharged from the main body in the direction of the arrow enters the top tray 221 by the gate 224 as indicated by a dotted line. The maximum capacity of the top tray is 300, and when 300 sheets are stored, the main body temporarily stops. However, purged paper, blank paper, and jammed paper are not counted as 300 sheets. FIG. 5 is a schematic view of the operation mechanism of the stacker, wherein 2230 is a stacker lift motor, 2231 is a lower limit switch of the stacker, 2232 is a limit switch of the upper stacker, 2233 is a stacker paper detection sensor, and 2234.
Is a compiler tray paper detection sensor. When the sheet discharged to the compiler tray 222 reaches the maximum capacity, the stacker lift motor 2230 rotates to raise the stacker tray 223, and the compiler tray 222
To receive the paper ejected.

In the split compiler mode: At the pitch timing, information of paper feeding / non-feeding, information of scanning / non-feeding, and discharge information can be known. 2. From the scheduled data (stored in the ROM), it is possible to determine at the end (LAST) of the divided set whether or not the compiler is to be discharged. It is determined on the schedule whether or not to discharge the compiler based on the information of the LAST data (SET LAST) of this set. When the pitch is canceled and the processing of the pitch is performed again, the SET L
AST information is not newly created. 3. At the timing of the scan end (SCAN END), data such as SETLAST and split compiler ejection are sent to the CHM remote, and the data is made to correspond to the paper (the data is attached to the paper). The above data is transmitted to the U / I when display is required. 4. Data is attached to each sheet of paper going from the copier body to the output device (OUTPUT).
The PUT sees this data, and if the flags of the divided compiler discharge and the compiler discharge are set, the compiler discharges the paper. When the sheet is discharged from the OUTPUT, the information (S
ET LAST data, etc.). 5. Compiler ejection includes pitch skip (PITC
H SKIP) is required, but since the sequence manager (SQMGR) has a necessary pitch, no paper interference occurs.

Next, the details of the divided job will be described. The divided job is to execute the job by dividing the schedule. The mode that must be used for the divided job is only the S / D mode in the RDH mode: two originals, R / L ≧ 51 D / D mode: one original, R / L ≧ 51. In the above modes (S / D mode, D / D mode), the following calculation is performed. Set number (R / L) Ｌ50 = (quotient) (remainder) If the value of (remainder) is finite, the number obtained by adding 1 to the value of (quotient) is the number of divided jobs. For example, when R / L = 60 (see (c) of FIG. 6 below), (60) ÷ 50 = 1... Remainder 10. Therefore, the number of divided jobs (the number of divided unit jobs) Becomes 2.

FIG. 6 is an explanatory diagram of an example of a divided job. As shown in FIG. 6A, job data is composed of 2 bytes, the set number of copies is 10, and the number of copies is 1. Set. When the data of the number of copies constituting the job data is limited, the job is divided. FIG.
(B) and (c) are illustrations of how to make a copy.
, Is the first original SIDE1 in the part job number
Side copy is a process for copying the second original SIDE2. Part job numbers are separately stored in a table, and are used by the sequence manager (SQ
MGR). In the example of FIG. 16D, when the limit number of DPX trays is 50,
For a job with an R / L of 30, the number of times of the job is 1, and the copy operation is in the normal mode. When the R / L is 51, the set number of sheets is 1, the number of copies is 1, and the number of jobs is 2. Therefore, in (b), once → is executed once, and subsequently, once → is executed once. Then, an end divided job is set. When the R / L is 102, the number of copies is 2, the number of copies is 2, and the number of jobs is 3,
How to make a copy in (b) is once → once →
The end is once → once → once → once. Note that recovery in a divided job is, for example, R / L =
When the recovery is performed after the copying machine stops when the part job has just finished in step 102, the end of the 50-page SIDE1 can be known after the recovery, so the part job is copied two more times and three more times. . If R / L = 102 and the processing is stopped when the processing is completed, it is known that 50 sheets of OUTPUT have been output after recovery, so the copying is executed two more times.

FIGS. 7 and 8 are more detailed explanatory diagrams of the divided job. From the job flow diagram (JFD) of SQMGR, the scheduled job is shown in FIG.
It is sent as follows. Reference numerals 170 and 171 denote two unit jobs when each part job is not a divided job.
It is divided into two part jobs 170 and 171. Number of each part job (124, 1, 11, 71, 81,
124) is a pitch number, which is selected from a table indicating the content of processing

FIG. 8 shows a specific example in the divided job mode shown in FIG. 7. FIG. 8A shows an example in which R / L = 30 and the limit number of DPX trays (maximum capacity) = 50. There is no need to make a split job. Therefore, since the mode is the D / D mode, (124) → (1) for SIDE1
→ 30 times for (11) job, SIDE2 (7
1) 30 (81) → (124) jobs are copied 30 times. (B) is an example of R / L = 103. In this case, based on the above calculation (103 ÷ 50 = 2, remainder 3), SIDE1 is performed 50 times → SIDE2 is performed 50 times → S
IDE1 is executed 50 times → SIDE2 is executed 50 times → SIDE1 is executed 3 times → SIDE2 is executed 3 times, resulting in END. In addition,
(C) is an example of JFD when D / D and the number of documents = 1. Next, the set number of sheets for each part copy will be described.

FIG. 9 is an explanatory diagram of the recovery information.
191 is OUTPUT in the unit of division at the time of division job
The number of completed copies discharged to OUTPUT, 102 is the number of SIMP copies before completion discharged to OUTPUT, and 193 is OU
The number of SIDE2 copies before the set completed discharged to the TPUT, 194 is the set completed SO in the DPX tray
The number of completed DE1 copies 195 is the data of the number of SIDE1 copies before the set is completed in the DPX tray. The data 191 indicating the number of completed OUTs of the recovery job is always "0" except in the divided job mode. At the start after the previous part job is completed among the part jobs constituting the divided job, all the recovery information is “0” because there is no completed part.

The set number of copies for each copy of a part job in a divided job is determined as follows. When the number of copies of the recovery information of the continuous part jobs is the same as the copy surface ↓. SIDE1: Set number of copies-SIDE2 completed number-SIMP completed number SIDE2: Set number of copies-SIDE2 completed number Value <the value of the next job... SIDE1: 50−SIDE2 completed number −SIDE1 completed number −SIMP completed number SIDE2: 50−SIDE2 completed number Previous job value> next job value...

As described above, the divided job in the RDH mode is divided into the collate mode in the S / D mode and the collate mode in the D / D mode when the number of originals is 2 and the R / L is 51 or more. This is executed when the number of sheets is 1 and R / L is 51 or more. Thus, for a unit job exceeding the maximum number of sheets accommodated in the DPX tray (here, 50 sheets), the job is divided and the divided job is executed, thereby smoothly executing a copy job having an R / L of 50 or more. be able to.

[0033]

As described above, according to the present invention,
A minimum unit that includes an automatic document feeder having a document recirculation function and a paper output device having a compiler discharge function for discharging a predetermined set of copied paper in units of one set, and executing a unit job specified by a user interface. Means for scheduling the control data relating to the job as a set of part jobs corresponding to the run length of the photoconductor, a unit job control means for controlling the execution of the unit job, and a part job control means for controlling the execution of the part job And a copy unit having a minimum unit job control unit for controlling a minimum unit job constituting a part job, in a mode in which the number of sheets exceeding the limit number of sheets of the DPX tray is entered, one unit of job is divided into a plurality of schedules at the time of scheduling. Divided into By that to perform the copy operations have, it is possible to improve the efficiency of the copy operation.

Claims (1)

(57) [Claims] An automatic document feeder having a function of recirculating a document; and a paper output device having a compiler discharge function for discharging a predetermined set of copied sheets in units of one set.
The pitch unit which is the minimum unit job for executing a unit job determined according to the instruction from the user interface
Means for scheduling the control data relating to job as a set of mass of the part job corresponding to the run length of the photosensitive member, and a unit job control means for controlling the execution of the unit job, part job control means for controlling the execution of the part job And a minimum unit job control means for controlling the pitch job , which is a minimum unit job constituting a part job, in a copying machine having a unit determined according to an instruction from a user interface.
Job exceeds the maximum capacity of the copier tray.
If the job requires the paper to be
The maximum number of copy sheets discharged to the tray
Part job and the maximum number of sheets
Into multiple part jobs consisting of multiple part jobs
If the split compiler job you need is
The divided compiler job is referred to as the plurality of part jobs.
Job control means for scheduling by counting the number of copy sheets discharged to the tray
When counting up to the maximum capacity of the tray
Split compiler discharge information (split compiler job execution
The information is detected as discharge information of the paper stored in the tray
Split Compiler Eject Generates Piler Eject Command
Control means, and scanning of the original in response to the compiler discharge command
SKIP control hand to stop the execution of
A divided compiler ejection device , comprising: a stage; and output control means for causing the paper output means to execute the compiler ejection in response to the compiler ejection command.
