2. Description of the Related Art Conventionally, in an image processing apparatus such as a printer, a scanner, a copying machine, a copier / FAX multifunction machine or the like, which is equipped with an automatic document feeder for automatically feeding a document to a document reading section, When a document or transfer paper is jammed, it is necessary to recover the document. That is, it is necessary to restore a predetermined number of originals and read the originals again after the original is jammed.

Japanese Unexamined Patent Publication (Kokai) No. 2-66586 discloses an "original recovery system" which is an invention relating to recovery after a jam of a copying machine. In this document recovery method, the number of returned documents is calculated based on the number of fed documents and the number of discharged sheets. Further, in the above document recovery method, there is only one type of job table to be controlled, which indicates the job status at that time.

According to the above publication, document recovery is
It is performed based on the state of conveyance of the document. The conveyance state of the original document is grasped by finding the position of the original document using a counter for the original document.

For example, as a counter for manuscripts,
Preliminary paper feed counter A that counts when a document has been conveyed to the preliminary paper feed position of the automatic document feeder, paper feed counter B that counts that a document has been conveyed to the original reading position of the automatic document feeder, automatic Prepare a paper output counter C that counts the fact that the original has been conveyed to the original output position of the original conveying device, and a paper discharge counter D that counts that the transfer paper that has been copied onto the original is discharged outside the device. The state of conveyance of the document is grasped based on these counters.

In the automatic document feeder, when the preliminary paper feeding is completed, the preliminary paper feeding counter A = A + 1, and when the paper feeding is completed, the preliminary paper feeding counter A = A-1 and the paper feeding counter B = B + 1, the paper output is completed. If the paper feed counter B
= B-1 and output counter C = C + 1, and when the transfer paper for the original is completely discharged, the paper discharge counter D =
It becomes D-1.

Here, if a jam of the transfer paper occurs,
The number of originals returned M is SS (single sided / single sided)
It looks like this:

When the paper discharge counter D is not 0, that is, when the copy of the discharged original is not completed, M = D + A + B, and when the paper discharge counter D is 0, that is, the paper is being fed. When the transfer paper which has been copied to the original is jammed, M = 0.

In this way, the number of originals to be returned is calculated from the value of each counter, and the originals are recovered.

[0010]

However, in the above-mentioned conventional document recovery system, in order to indicate the states of the document and the transfer sheet, the counters provided at different time series are set to +1 or -1, respectively. There is a possibility that a problem of subtracting the counter value from 0 to 1, that is, a problem of setting the counter value to -1 may occur.

For example, in the case of a type in which the automatic document feeder is capable of opening and closing with respect to the document placing table which is the reading position of the document, the mode in which the document is automatically conveyed while the document remains on the document placing table. When the copying is started at 1, the copying machine discharges the above-mentioned original from the original placing table at the start of copying. At this time, 1 is subtracted from the value (initial value) of the preliminary paper feed counter A to be -1. The value of the counter A being -1 means that the value of the counter A is FF.
Therefore, there is a problem that the copying machine issues an erroneous instruction such as an instruction to return 255 (FF) originals.

The present invention has been made to solve the above problems, and an object of the present invention is to perform image processing that enables accurate and easy recovery of a document when a document or transfer sheet is jammed. To provide a device.

Therefore, each control routine provided for copying is executed based on the management table created for each original, so that, for example, the present FAX multifunction machine is operated in the interleaf sheet mode (original page and interleaf sheet tray are designated. Even in the mode of inserting a slip sheet during normal copying), the slip sheet mark is displayed in the management table of the document to be the slip sheet, GB shown in FIGS.
By simply storing “1” in 4, the paper feed routine among various control routines can easily switch the paper feed tray to the interleaving paper tray by referring to the management table.

Therefore, if a control table is created for each document and various control routines are executed with reference to this control table, various controls in the FAX multifunction machine will be simplified.

A specific example of the management table 102 will be described below.

[0209] First, DD or D in ADF mode
A management table at the time of starting a job for an S mode and A4 size document will be described. Here, the document section shown in FIG. 9 has areas for storing information about the document ID, the document size, and the exposed surface of the document, and these information are determined when the job starts.

When the job is started, as shown in FIG.
First, the document ID of the first document is set to "0001", and the document IDs are set to "0002", "0003" ... "0100" from the second document on each management table. Further, the management table of the same document is described such that the exposed surface is the back surface at the odd number and the exposed surface is the front surface at the even number.

At this time, in the case of double-sided exposure in which the front and back of one original are exposed, the same original is used for both front and back. In this management table, the number of originals is limited to 100 at maximum.

Further, the document size stored in the document section is also described at the start of the job. Since the original size is set for each original, it is possible to easily describe which original ID has changed the original size even if the original size changes due to detection during conveyance of the original.

Further, since the original size can be known promptly even when the automatic paper selection and the automatic magnification selection are performed by the original size, it is possible to smoothly calculate the paper size or the magnification corresponding to the original. A highly efficient system can be realized.

As described above, when a double-sided original is exposed in the ADF mode, one original is exposed from the back side, and then the front side is exposed. That is, in the case of a plurality of originals, the back side and front side of the original 1, the back side and front side of the original 2,
The original 100 is exposed in the order of the back surface and the front surface. Incidentally, when exposing a double-sided original in the RDH mode, the back side of the original 1, the back side of the original 2, ...
0 back side, original 1 front side, original 2 front side, ... original 1
The exposure is performed in the order of 00 surface.

Further, manuscript management provided in the management table
The bit stores information on whether or not it is the final manuscript. In the management table shown in FIG. 16, the state created at the start of the job is shown, and therefore the original 100, which is the final original, does not yet have a bit indicating that it is the final original.

However, when the job starts, the reading operation of each document progresses, and the final document is determined in the document handling routine, the document management bit of the management table immediately displays information indicating that the document is final. Written.

When the information of the final document is written in the management table in this way, it is possible to easily determine the end of the job.
Moreover, there is an advantage that the tray switching can be smoothly performed when only the final sheet such as a cover copy is fed from another sheet feeding tray.

In this FAX multifunction peripheral, it is possible to set an original count mode for counting the number of originals. The management table in this document count mode will be described below.

The management table in the document count mode is
As shown in FIG. 17, "S" indicating idle conveyance is stored in the information bit indicating the exposed surface of the exposed original of the original section. Then, the original is conveyed until it is determined that the original that is being conveyed in the empty state is the final original. Then, if it is determined that the original document to be idle-conveyed is the final original document, a bit indicating the final original document is written in the information bit indicating the final original document in the management table. The original ID of the original determined to be the final original is the number of originals.

The FAX compound machine of the present invention is an automatic document feeder.
Depending on the progress of the operation of the device and image processing device,
Processing information of the specified document in the above management table for each operation
In order to obtain the above , the control unit 100 has a table reference unit that refers to the management table, and based on the processing information of the management table referred to by the table reference unit,
The operation control of the automatic document feeder and the image processing apparatus is performed.

By referring to the management table by the table reference means, the control section 100 can detect the document state in the management table.

The table reference means has a plurality of pointers for indicating the processing information recorded in the management table for each operation of the original or the like in the automatic document feeder or the image processing apparatus. Therefore, the control unit 100 controls the automatic document feeder 2 and the image processing apparatus based on the processing information of the management table to which the pointer is moved.

That is, the pointer for document transportation moves to the processing information of a predetermined document in a plurality of management tables, and each device of the FAX multifunction peripheral based on the processing information of the document indicated by the pointer for document transportation. Is controlled.

The pointers for conveying the original document include three pointers for starting the original, ejecting the original, and completing the ejection of the original. For SCANNER operation, there are two pointers, a scanner pointer and a recovery pointer.

Then, each of the pointers is incremented by 1 when an event corresponding to the pointer occurs, and moves to the management table of the next document. Here, the pointer being incremented by 1 means that the pointer moves to the management table of the next document.

In this embodiment, the document start pointer is incremented by 1 when the document is conveyed, the document ejection pointer is incremented by 1 when the document is ejected, and the document ejection completion pointer is incremented by 1 when the document is ejected. . Accordingly, it can be easily determined that the document corresponding to the management table existing between the document transport start pointer and the document discharge completion pointer is in the document transport path.

The pointer for the scanner is incremented by 1 every time the final return is completed, and the pointer for recovery is incremented by 1 when the exposure of the original is completed. This allows
With the two pointers for SCANNER, you can immediately determine the original document that is being exposed.

FIG. 18 shows SS as the exposure mode of the document.
In the / SD mode, a management table for copying four originals is shown and the position of each pointer at this time is shown.

The management table shown in FIG. 18 describes that the fourth original is already the final original. Therefore, in this state, each pointer moves by +1. That is, the pointer moves to the next management table by moving +1.

In the FAX multifunction machine having the above construction, FIG.
As shown in (4), when the original needs to be returned due to an original jam, etc., the most upstream pointer of the original, that is, the pointer that is incremented by 1 at the start of the original conveyance, and the recovery pointer, that is,
The number of originals to be returned can be easily determined by calculating the difference between the original ID and the pointer that is set to +1 when the original exposure is completed . Moreover, since the original ID is known, it is possible to easily determine which original should be returned by the original ID.

Further, in FIG. 18, pointers for the original may be those indicating the uppermost stream of the original, indicating the completion of discharging the original, and indicating that the original is being discharged.
That is, it suffices to have a pointer that increments by +1 each time the document is started, a pointer that increments by +1 upon completion of ejection, and a pointer that increments by +1 when ejection starts.

For example, in order to know the number of documents to be handled, it is easily judged by calculating the value of the document ID between the discharge completion pointer and the conveyance start pointer, and the position of each document is also clearly grasped. it can.

Further, the number of originals until the completion of feeding is the original I between the discharge start pointer and the conveyance start pointer.
It can be judged by the value of D.

As described above, since the pointer set so as to always increment by +1 while the job operation is in progress is used, the counter is incremented by +1 or -1 as in the conventional case.
The state of the original can be grasped more accurately and easily than in the case where the state of the original is calculated.

Moreover, since the state of the document can be grasped by the minimum necessary number of pointers, the control can be efficiently performed without having an unnecessary pointer.

Next, the management table in the OC mode will be described below.

The management table in the OC mode is shown in FIG.
As shown in FIG. 9, when the job is started, information indicating the final document is set, and an effective mark is set in the management table mark, so that the document reading control can be performed with only one management table.

Next, the management table in the book copy mode will be described below.

In the book copy mode, copying is performed by considering that two pages of spreads are one original.
As shown in FIG. 2, two management tables in which different document IDs are set for one document are prepared. And 2
Information indicating the final document is set in the management table with the document ID of the page “0002”.

[0240] Further, the manuscript ID "00" which is the manuscript of the second page
In the management table of 02 ", the start position in the SCANNER section is set to the same value as the end position in the SCANNER section of the management table of the document ID" 0001 "which is the first page of the document. For example, as shown in FIG. In the management table of the document ID “0001”, the scan start position of the SCANNER is set to “0” and the end position is set to “210”, and in the management table of the document ID “0002”, SCANNE is set.
The scanning start position of R is "210" and the end position is "42".
It is set to 0 ".

As a result, even when re-copying from the second page in the book copy mode, it is only necessary to refer to the management table of the document ID "0002", and therefore the pointer also points to the management table of the document ID "0002". Just good. Therefore, the reliability in controlling the document reading operation can be improved.

The scan width can be easily changed only by changing the start position and the end position set in the above management tables.

Here, regarding the processing at the star of the new original reading operation (job) in the FAX multifunction machine,
This will be described below with reference to FIG.

First, when a new job is started,
It is determined whether or not the job is already in progress (S31).

If the job is in progress in S31, it is determined that the job is in progress, the contents of the management table are left as they are (S32), and the values of the respective pointers are left unchanged (S33).

On the other hand, if the job is not in progress in S31, the management table used in the previous job is reset to create a new management table (S34), and each pointer is reset (S35).

Thus, if the job of the original document for which the management table has already been created is continuing, the contents of the management table and the value of each pointer are left unchanged, and if the job is completely new, the previous job If the contents of the management table and the value of each pointer are controlled so as to be reset, it is possible to determine whether the job is new or ongoing only by determining whether the job is in progress. it can.

If the job is not in progress at the time of starting the job, it is determined that the job is a new job, the management table of the previous job and the values of the pointers are cleared, and a new management table is created. The job is executed as a new job without being affected by the previous job.

The FAX multifunction machine having the above-mentioned structure ideally has as many management tables as the number of originals, but the storage capacity of the RAM 76, which is the storage means installed in the apparatus, is also limited. Therefore, RAM7
It is necessary to use 6 effectively.

Therefore, a specific description for effectively using the RAM 76 will be given below.

In the present invention, in order to effectively use the RAM 76, first, the number of management tables that can be created in the RAM 76 is set. When the number of management tables corresponding to the manuscript exceeds a preset first numerical value (a value smaller than the number of originals), the management tables up to that point are preset to a second numerical value (more than the number of originals). Small and first
Value that is greater than the value of). Then, when the management table corresponding to the original exceeds the second numerical value, the management table existing between the first value and the second value is rewritten.

When the number of originals exceeds the number of management tables that can be created in the RAM 76, the FAX multifunction machine determines that the number of originals is unknown. This allows
As shown in FIG. 22, in the management table created in the RAM 76, since the number of originals is unknown at the time of the reading operation of the first original, it is uncertain for the second and subsequent originals. Therefore, information indicating indetermination is stored in the management table mark of the management table corresponding to the second and subsequent documents.

Now, the process of creating a management table when the number of originals exceeds the number of management tables that can be created in the RAM 76 will be described below with reference to FIGS. 22 and 23. In the management table creation processing, a case will be described in which the first numerical value is 50, the second numerical value is 100, and the number of management tables that can be created in the RAM 76 is 100.

Incidentally, the management table shown in FIG.
It is assumed that the mode is set to SS mode or SD mode, the document size is set to A4, the paper size is set to A4, and the magnification is set to 100%. The second numerical value is RAM7.
It is also the limit value for creating the management table in 6.

Every time the value of the recovery pointer exceeds 50 which is the first numerical value, the one before 50 in the management table is set as the manuscript ID = 0101, 0201, ...
Rewrite up to the manuscript ID = 0150, 0250 ...

Furthermore, the value of the recovery pointer is the second
When the numerical value of 100 is exceeded, 51 to 100 of the management table are rewritten as ID = 151, 251 ,.

By setting the remainder of the pointer value divided by 100, the number of management tables does not exceed 100, and only the document ID can be continued. Further, since the management table also changes according to the document ID, the control is simplified and the reliability is improved.

A program relating to such management table creation processing is stored in the ROM 75 and is read out when necessary.

Next, the flow of the management table creation processing when the number of originals is 200 and the number of management tables that can be created is 100 will be described below with reference to the flowchart shown in FIG.

First, when the recovery pointer is updated, R
The management table creation processing program is read from the OM 75, and the value of the recovery pointer is incremented by +1 each time the management table is created (S41).

Then, the value of the recovery pointer is 51
It is determined whether or not (S42). Here, if the value of the recovery pointer is 51, 1 in the management table
The 50th to 50th contents are rewritten so as to correspond to the 101st to 150th contents of the management table (S43).

On the other hand, if the recovery pointer is not 51 in S42, it is determined whether the recovery pointer is 101 (S44). Here, if the recovery pointer is not 101, the process ends.

If the recovery pointer is 101 at S44, the 51st to 100th contents of the management table are rewritten to correspond to the 151st to 200th contents of the management table (S45).

Then, the value of the recovery pointer is returned to 1 (S46), and the process ends.

If the management table creation processing is controlled as described above, the number of management tables can be 100, which is the second numerical value that can be created in the RAM 76, and the RAM 76 can be effectively used.

At the time of updating the above recovery pointer,
This is the point at which the paper is completely discharged and the original is no longer needed, or if it is a digital system, the exposure is completed and the exposure image data is stored in the RAM 76.

The contents and operation of the management table in the RDH mode at the time of a copy job will be described below with reference to FIG. Note that FIG. 24 shows the operations of the management table and each pointer in the DD mode and two originals.

In the DD mode, 1 is set for two originals.
Exposure is performed in order of the back surface of the first original, the back surface of the second original, the front surface of the first original, and the front surface of the second original. That is, the back side copy is performed on the document having the document IDs 0001 and 0002, and the front side of each document is copied in the next circulation.

Therefore, a desired copy is completed by repeating this cycle a predetermined number of times. That is, in the DD mode,
If all pointers are reset in the final manuscript of the second round and the contents of the management table are circulated for each copy, control can be surely performed.

In the above description, the example in the DD mode is shown, but the present invention is not limited to this. For example, in the SS mode, the control can be performed by resetting the pointer with the final manuscript of the first cycle.

In the FAX multifunction machine, when copying other originals during the job, interrupt shovel processing can be performed. This interrupt job processing will be described below with reference to FIG.

First, when the job is started, it is determined whether the job is an interrupt job (S51). If it is determined that the job is an interrupt job, the contents of the management table in the job are temporarily saved as they are, and another new management table, that is, a management table for the interrupt job is created (S52). Then, each pointer is reset (S53).

In this way, the interrupt job is controlled using the management table for the interrupt job.

Next, in S51, if it is determined that the job is not an interrupt job, it is determined that the interrupt job is completed, and the copy job is continued with the contents of the management table saved before the interruption (S54), and each pointer is The value of is returned to the state before the interruption (S55).

As a result, the job before interruption is not affected by the interruption job, so that the copy job can be reliably controlled.

Recovery in the case of a document jam or a paper jam in the FAX multifunction machine having the above configuration will be described below with reference to FIGS. In this description, it is assumed that the automatic document feeder 2 has an ADF mode, a copy mode is an SS mode, and the number of documents is 7.

First, in the job of the above-mentioned seven originals, the original I
Before scanning the document with D = 0006, the document ID is 0007
A case will be described in which the paper feed start is completed, and the document jam occurs in the state where the copy is completed on the paper corresponding to the document whose document ID is 0004.

At this time, each management table has contents as shown in FIG. That is, the management table with the document ID 0005 indicates the completion of document discharge, and the document ID is 0006.
Management table indicates completion of document feeding and document setting, and a management table having a document ID of 0007 indicates completion of preliminary sheet feeding 2 which is preliminary sheet feeding to the second preliminary sheet feeding position. The management table 0008 indicates that the operation is waiting.

Therefore, the recovery pointer indicates the management table of the manuscript whose manuscript ID is 0005.
The N pointer indicates the management table of the document with the document ID 0006, and the document most upstream pointer has the document ID 0.
The management table of the document of 008 is shown.

Thus, each pointer points to the table to be controlled next. Therefore, in the document jammed state shown in FIG. 26, the number of documents to be returned is determined by the difference between the document ID values of the most upstream document pointer and the recovery pointer. That is, the number of returned documents is 8-5.
= 3 (sheets). Therefore, the originals to be recovered are the originals whose original IDs are 0007, 0006, and 0005.

As described above, the recovery original can be easily calculated by using the difference between the pointers.

From the original jammed state, when the cover of the automatic original feeding device 2 is opened and the original jam is released, the original ID is 0007000.
For 6,0005, the management table mark is set to invalid.

Therefore, the manuscript ID is 0007,000,000.
As shown in FIG. 27, since the management table marks of the document management tables 6,0005 are set to be invalid, the document management bit is set to wait for operation.

Then, the document jam is eliminated and the document I
When D sets 0007, 0006, and 0005 originals and restarts the original job, each pointer is moved to indicate the management table indicated by the recovery pointer, as shown in FIG. That is,
At restart, when the recovery pointer is invalid, align the other pointer with the recovery pointer.

At this time, the invalid mark of the management table mark of each management table is changed to a valid or indeterminate mark. That is, in FIG. 28, the document ID is 0005.
Management table is valid and other document IDs are 0006
The management tables of ~ 0008 are indeterminate.

As described above, when the original job is restarted, by aligning all the pointers with the position of the recovery pointer, the recovery position, that is, the original ID000.
Since the document feeding start and the document scan start are performed from the document No. 5, the recovery operation can be easily realized without any contradiction.

In the FAX multifunction machine having the above-mentioned structure, a double-sided mode for forming images on both sides of paper, that is, a DD mode or S mode
In the D mode, the sheets stacked on the intermediate tray 37 (FIG. 2) may be pulled out, or the sheets may run out due to double feed or the like, and copying may have to be restarted from the back side of the sheets.

The processing using the management table in such a case will be described below with reference to FIGS. 29 to 32. In this description, the copy mode is SD mode,
This is performed when the number of originals is 6 and the sheets in the intermediate tray are insufficient.

First, when the copying is stopped in the state as shown in FIG. 29, the originals I to be stacked on the intermediate tray are set.
When there is a shortage of paper sheets corresponding to the document of D 0003, copying must be started from the shortage of the paper sheets corresponding to the document of document ID 0003.

Therefore, in the management table corresponding to the document whose document ID is 0003, as shown in FIG. 29, a completion mark indicating exposure completion is set in the management table mark and document discharge completion is indicated in the document management bit. Information is set. With this, the recovery pointer becomes
The document ID of the next document is moved to the management table 0004.

However, as described above, the document ID is 0.
When the copying is started from the shortage of the paper corresponding to the document of 003, the document ID is 000 as shown in FIG.
A valid mark is set in the management table mark of the management table No. 3, and the recovery pointer is returned to the valid top management table.

In the above case, the number of originals to be returned is the difference between the original ID values indicated by the most upstream original pointer and the recovery pointer, that is, 6-3 = 3 (sheets). That is, the original having the original ID of 0003 is copied on the back surface of the second sheet in the double-sided copy mode. Therefore, when there is a shortage of sheets corresponding to the original having the original ID of 0003, the copy surface of the original corresponding to the original having the original ID of 0003 is not completed, so that the number of originals returned is 0006-0003 =. Can be three.

Then, when the cover of the automatic document feeder 2 is opened when the document is returned, as shown in FIG. 31, an invalid mark is set in the management table marks of the management tables of document IDs 0003 to 0006. It

As described above, the copying job is restarted with the invalid mark set in the management table mark of each management table of the return original. At this time, the original most upstream pointer and the SCAN pointer are moved to show the management table pointed to by the recovery pointer, as shown in FIG.

As described above, in the double-sided copy mode, when the sheets stacked on the intermediate tray are pulled out or the sheets run out due to double feed or the like and the sheets have to be restarted from the back side, as shown in FIG. By returning all pointers to the recovery pointer and recovering the job, consistent copy work can be realized.

Next, in the FAX multifunction machine having the above configuration,
Recovery processing in a copy job in the RDH mode as the document reading mode and the DD mode as the copy mode will be described below with reference to FIGS.

When the number of originals is 6 in the RDH mode and the DD mode, as shown in FIG. 33 (a), the control section 100 first sets the originals of the original IDs 0001 to 0006 on the back side. Then, the management tables set for the document IDs 0001 to 0006 are sequentially created with the exposed surface of each document set on the front side.

Therefore, in the copy job in the RDH mode and the DD mode, based on the management table shown in FIG. 33A, first, only the back surface of the original is copied, and then only the front surface of the original is copied. , It is designed to copy a double-sided original on both sides of a sheet. That is, the back side copy of all originals is made in the first circulation, and the front side copy of all originals is made in the second cycle.

When the copy job in the RDH mode and the DD mode is stopped due to a document jam or the like, the recovery pointer is, for example, as shown in FIG.
The management table in which the document ID is 0003 and the exposed surface is set in the table is shown. At this time, in the RDH mode, since the original is returned to the placed state when stopped, the original is conveyed from the first page at the next start.

Therefore, in the management table in which the exposed surface is to be set in the table, the document ID is 0001,000,000.
The second document is conveyed in an empty state, and exposure is started from the document having the document ID of 0003.

That is, at the start of recovery, FIG.
The management table for recovery as shown in FIG.
3A is created separately from the basic management table shown in FIG. 3A, and the copy job is controlled based on this recovery management table.

That is, in the management table for recovery, the document IDs are 0001 and 0002, and the exposure surface of the management table whose exposure surface should be set to the front side is SKI.
When P is set and the document IDs are 0003 to 0006, the table is set on the exposure surface of the management table.

Then, the original feeding pointer (original pointer) is returned to the management table corresponding to the original with the original ID of 0001 according to the placed state of the original, and the original with the original ID of 0001 is started to be conveyed. , The original document ID is 0002, and the original document ID is 0003
The exposure of the surface of the original document is started.

Further, when the pointer is moved to the management table corresponding to the document with the document ID 0006, that is, the management table corresponding to the final document, it returns to the beginning of the basic management table shown in FIG. 33A and the recovery is completed.

According to the above control, even in the RDH mode, at the time of recovery, the copy management job is controlled by the recovery management table provided separately from the original management table, so that the recovery can be performed reliably and easily. It will be possible.

As described above, in the management tables in the RDH mode and the DD mode, as shown in FIGS. 18 and 33 (a), only the back surface of the original is exposed in the first round, and the second table is exposed.
It is arranged so that only the surface of the original is exposed in the round. As a result, the operation pattern in the copy job is
Since the originals are presented in order of presentation to the original exposure unit 3 in time series, more accurate control is possible.

As shown in FIG. 16, the management table in the ADF mode and the DD mode is arranged so that the back surface and the front surface of one original are continuously exposed. In this case as well, the operation patterns in the copy job are expressed in the order of the pages of the original in time series, so that more accurate control is possible.

[0308]

As described above, the image processing apparatus according to the first aspect of the present invention has the document reading unit for reading an image from a document and the automatic document feeder for sequentially presenting the document to the document reading unit. in the image processing apparatus, is created for each document, a management table for the document of operation patterns for the reading process of the document is recorded as the processing information, the automatic original

Based on the value of the manuscript ID between the
This is a configuration for determining the number of originals being handled .

Therefore, for example, when a trouble such as a document jam occurs, it is easy to recover the number of originals to be returned and which original should be returned from the processing information of the management table moved by the table reference means. Since necessary information can be easily obtained, recovery can be performed easily and accurately.

Information necessary for the above recovery, for example, information such as "how many originals from the start of feeding and returning them to the original tray" is displayed on the display unit of the automatic document feeder or the image processing apparatus. By displaying, it is possible to improve the operability, and as a result, it is possible to improve the accuracy of recovery of the document.

[0311] Further, referring to the multiple pointer, i.e. by referring to the management table in which each pointer is pointing, the conveyance status of the document is easily determined, the more accurately the original reading operation There is an effect that it can be performed.

Also, as a pointer for manuscript management,
Pointer for starting document transport and pointing point for completing document ejection
Since it includes a starter and
Calculating the value of the manuscript ID with the tat pointer

The location can be clearly understood.

As described above, the image processing apparatus according to the second aspect of the present invention, in addition to the configuration of the first aspect , has the management table according to the selected image processing mode or the type of the automatic document feeder. , The page order of the manuscript or the order in which the manuscript is presented to the manuscript reading unit.

Therefore, in addition to the effect of the configuration of claim 1 , there is an effect that the document management can be accurately performed, and the control such as the document reading operation and the recovery can be accurately performed.

As described above, the image processing apparatus according to the third aspect of the present invention, in addition to the configuration of the first or second aspect , manages each original document in addition to the document processing information in the management table. Document management information for reading, document exposure information indicating whether the front side or the back side of the document is exposed, and document conveyance information indicating whether or not the document is conveyed as it is without being conveyed. It has a structure.

Therefore, in addition to the effect of the first or second aspect of the invention, in addition to the document processing information, the document management information, the document exposure information, and the document transport information are added to the management table, so that the document can be further processed. Since the management can be performed with high accuracy, there is an effect that recovery can be performed accurately and swiftly when a trouble such as a document jam occurs.
