Abstract

PROBLEM TO BE SOLVED: To reduce user's load by performing work skillfully which stacks respective parts of copies of originals to be divided and unites them into one, because a memory becomes full when it reads a part of the original. SOLUTION: When an operation is continued with a full memory, partition paper is inserted after the last copy of read image, when the memory is full and before the front copy of the next cycle after the memory is cleared in each part. In the shown diagram, five originals are set to three copies respectively, partition paper is inserted after the last copy of respective three copies of the 1st to 3rd originals that make the memory full, and they are sorted into three pats and outputted. After interruption, partition paper is inserted before the front copy in the next cycle, and then a printing operation is performed to a 4th and succeeding originals. Furthermore, it is possible to perform the work while confirming a character and a symbol without being at a loss, even though the number of parts and divisions is increased to make the work complicated by printing the character and symbol representing that a part of which copy a divided part belongs to.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus for making a plurality of copies based on a plurality of originals, and more particularly, to a case where a memory becomes full during reading of a plurality of originals. The present invention relates to a device in which a partition sheet is inserted into a break of each part so that an operation of combining the divided copies into one can be easily performed.

[0002]

2. Description of the Related Art In a conventional copying machine, when a plurality of copies are made based on one original group consisting of a plurality of originals, a separating sheet is provided at a break of each copy so that sorting can be easily performed later. There is a copy partition mode for inserting a. FIG. 15 is a view for explaining an example of a state in which copy partition paper is inserted into each section by the conventional machine. In FIG. 15, for example, in a case where three copies are made with five originals, if the copy partition mode is set as [sort + repeat three copies + copy partition], as shown in FIG. The partition paper (colored paper) set in the partition paper tray is inserted. Thereafter, similarly, a partition sheet is inserted at the end of each copy of the document.

In the case of an image forming apparatus such as a digital copying machine in which a document image is taken into an internal memory of the main body, when the capacity of the internal memory becomes small, the operation is temporarily suspended as the memory is full. After that, it is possible to continue the copy operation, in that case, print out the read image for the number of copies, clear the memory full state to increase the free space of the internal memory, A new document following the document image captured before the interruption is read. In this case, the copy output as a result is divided before and after the interruption. FIG. 16 is a diagram for explaining a copy output state when the operation is temporarily suspended due to memory full in the conventional apparatus. In FIG. 16, for example, in a case where three copies are made with five documents, the copy partition mode is set to [sort + repeat three copies + copy partition], and it is assumed that the conditions are such that memory full occurs with three documents. As shown in the drawing, the operation is interrupted for the third document, and three copies of each copy are sorted and output first. Note that insertion of a partition sheet is not supported in this interruption operation. After the interruption, the operation for the fourth document and thereafter is performed, and two copies of each document are sorted and output.

In a copying machine capable of producing a plurality of copies for each copy based on a plurality of originals, a machine equipped with a mechanism for shifting a discharge position for each copy when discharging a completed copy. There is. Copies are performed by a machine equipped with such a shift mechanism, and when all copies have been completed, the copies of each copy output to the paper output tray are stacked in a different level for each copy. Therefore, it is possible to obtain a copy of each unit without troublesome work such as a need to sort the copies of each unit by the user.

[0005]

By the way, in a machine having a function of performing a shift discharge operation, the shift discharge operation is performed even when the above-mentioned memory-full operation is performed. Copies are ejected in a state where they are stacked on different levels, but the copy creation / output operation is still divided before and after interruption,
In order to unify each copy, it is necessary to overlap the divided copies. In particular, when the number of copies and the number of copies increase (the number of documents increases when the number of documents increases), the work becomes complicated and time is required for the work. Would. An object of the present invention is to copy the image stored at this point in time when the memory becomes full in a state where a part of the original is read in order to make a plurality of copies of the number of originals exceeding the capacity of the internal memory and the stored image is output at this time. In view of the problem of the prior art that the output is divided and the work of superimposing and integrating the parts of the divided copy becomes a heavy burden on the user,
It is an object of the present invention to unify the divided copies easily and conveniently for the user, and to reduce the labor required for the operation as much as possible.

[0006]

According to a first aspect of the present invention, in an image forming apparatus provided with a storage device for storing a read image, the storage device becomes full when a part of the document is read.

Referring to FIG. 1, a plurality of document bundles placed on a document table 2 of an automatic document feeder (hereinafter, referred to as an ADF) 1 with the image side of the document facing up start on an operation unit (see FIG. 2). When the key 25 is depressed, the original is fed from the lowermost document to a predetermined position on the contact glass 6 by the feed roller 3 and the feed belt 4. Reading unit 5
0, the image data of the original on the contact glass 6 is read, and then the original that has been read is discharged by the feed belt 4 and the discharge roller 5. Further, when the document set detecting means 7 detects that the next document is present on the document table 2, the document is fed onto the contact glass 6 in the same manner as Hanae Maehara. Feed roller 3, feed belt 4, discharge roller 5
Is driven by a transport motor (not shown).

The transfer papers stacked on the first tray 8, the second tray 9, and the third tray 10 are supplied to the first paper feeding unit 1 respectively.
1, the second paper supply unit 12 and the third paper supply unit 13 feed paper, and the vertical conveyance unit 14
Conveyed to a position where it comes into contact with. Reading unit 50
Is written on the photoconductor 15 by modulating the laser from the writing unit 57 with the image data, and passes through the developing unit 30 to form a toner image on the photoconductor 15. Then, the toner image on the photoconductor 15 is transferred while the transfer paper is being conveyed by the conveyance belt 16 at the same speed as the rotation of the photoconductor 15. Thereafter, the image is fixed by the fixing unit 17, discharged out of the apparatus by the paper discharge unit 18, and stored in the paper discharge tray 19.

When an image is formed on both sides of the transfer paper, the transfer paper fed and imaged from each of the paper feed trays 8 to 10 is not guided to the paper discharge tray 19, and is used for path switching. By setting the branch claw 40 on the upper side, the stock is temporarily stored in the double-sided paper feeding unit 41. Then, double-sided paper feed unit 4
Is transferred again from the double-sided paper supply unit 41 to transfer the toner image formed on the photoconductor 15 again, and the double-sided branching pawl 40 for switching the path is set on the lower side. Thus, the transfer paper having the toner images formed on both sides is guided to the paper discharge tray 119. As described above, when images are formed on both sides of the transfer paper, the duplex paper feeding unit 41 is used.
Is used.

The operation unit of the image generating apparatus according to the present embodiment includes, as input keys, a plurality of mode keys for setting a copy mode, a numeric keypad for setting the number of copies, and a print key for starting a copy operation. A stop key for interrupting the copy operation is provided. The mode keys include a magnification key to change the magnification, a paper key to change the paper,
There are a density key for changing the density, a copy partition mode key for automatically inserting a partition sheet specified at a break between copies, and the like. In addition to the mode key, a key for initial setting of the machine is also provided, and the user can set partition paper (which tray is the partition paper) and the like. FIG. 2 schematically shows an example of this operation unit.
Referring to FIG. 5, each of the above-mentioned keys is
1, a numeric keypad 22, an SP mode initial setting key 23, a copy partition mode key 24, a print key 25, a clear / stop key 26, and an energy saving key 27 are provided.
At the same time that a message indicating the magnification and the state of the image forming apparatus is displayed, a mode key operated to set or cancel each image forming mode is arranged.

The user operates the keys on the operation unit to set the copy mode and starts copying. This apparatus is a digital machine, and does not directly project the image light from the set document onto the photosensitive member to form an image, but uses the CC of the reading unit 50.
The image data of the document is taken into the internal memory through the D image sensor 54. In the repeat copy, an image is formed on the photoconductor 15 using the captured image data. A document is placed on an ADF (automatic document feeder) 1 placed on a document table 2, conveyed sequentially to a reading position simultaneously with the start of copying, and discharged after the entire surface of the document has been read and scanned. The original can be read continuously until the internal memory is full. When the memory becomes full, print the image that has been read so far, empty the internal memory, and then select whether to continue reading the next original or discard all the read and unoutput images it can. As shown in the above-described conventional example (see FIG. 15), the basic operation when the memory becomes full is the same as the conventional memory full operation mode.

When the memory becomes full when a part of the original is read, and the copy of the read original is output when the memory is full, the memory is emptied, and the operation of reading the subsequent original and performing the copy output again is selected. Unless the memory becomes full as a result of the interruption due to the full operation, the copying is completed in a state where the copying is completed for each unit, but the copying is divided before and after the interruption. For this reason, the user performs the work of combining the divided copies for each copy and unifying them. In the present invention, a copy partition mode is performed in which a user can easily perform the unification work of the copy and insert a copy partition sheet between the divided copies so as to reduce the labor required for the work. The process of inserting a partition sheet performed here or the process of changing a sheet into a copy main body and inserting a partition sheet or a cover sheet is known, and this known partition sheet processing technique is added to the image forming apparatus.
By applying, the insertion of the partition paper of the present invention can be performed. An embodiment of a copy partition mode in which copy partition paper is inserted in a different form will be described below.

<Embodiment 1> In this embodiment, the memory becomes full when a part of the original is read, and a break is made at the end of the set when the operation is continued. In this embodiment, the memory becomes full. This is performed by inserting a partition paper at the end of the copy output every time the image printing is completed. FIG. 3 is a diagram illustrating a copy output state according to this embodiment. In this example, when three copies are made with five documents, the copy partition mode is set, and the conditions are such that memory full occurs with three documents. As shown in FIG.
In the first cycle, up to the third copy of the original document that is full of memory is output, a copy divider is inserted at the end of the copy, and a total of [copy + separator] are sorted into three copies for each copy. Is output. After the interruption, a printing operation for the fourth document and thereafter is performed, and two copies of each of the copies are sorted and output.

FIG. 4 is a flowchart showing an operation mode for inserting a partition paper at the end of a copy output of an image which has been read when the memory is full. The operation of this embodiment will be described below with reference to FIG. . It should be noted that the step numbers given in FIG. 4 are described in parentheses in the description for reference (the handling of the step numbers is the same in the following flows). The user is the ADF1 platen 2
A plurality of document bundles are placed with the image side of the document facing up, and the copy mode, the number of copies, and the like are set by operating the keys of the operation unit (FIG. 2) using the liquid crystal touch panel 21 and the numeric keypad 22. Press copy to start (S
1). The original is read by the CCD image sensor 54 of the reading unit 50, and the image data is taken into the internal memory. A document taken out of multiple documents is A
The data is sequentially taken into the internal memory through the DF1 and reaches the full memory capacity (memory full), but it is detected whether or not the memory is full (S2). When the memory is full, the intended copy cannot be obtained in one copy output process, so the user is asked to continue the operation (S3).

When the user presses a key on the operation unit, for example, a copy partition mode key 24 prepared to perform the operation mode of the present flow, and requests the continuation of the operation, the original is read to the internal memory up to the memory full state. Printing processing is performed using the image data (S4). Next, it is checked whether the printing of all the sheets of the read original is completed (S
5) After confirming the end, insert a separating sheet after the last copy of the original read up to the memory full. Since it is necessary to insert the partition paper for each copy, it is checked whether or not all copies are completed (S7).
The memory full operation of S6 is repeated. The way to insert the partition paper is controlled by the paper feed control of the main body for one of the paper trays in the image forming apparatus for the partition paper, or by a method of inserting the partition paper in a post-process to the copy discharged from the main body. Is also good. After the insertion of the divider has been completed for all numbers,
Clear the internal memory. Since clearing creates an unused free space in the internal memory, it is possible to store image data to be taken in from the original after the memory full which has been divided and left, and the remaining originals are again returned from the start step (S1) of this flow. Can be executed.

<Embodiment 2> In this embodiment, the memory becomes full when a part of the original is read, and a break is made at the end of the set when the operation is continued. In this embodiment, the memory becomes full. Inserting a partition paper every time image printing is completed, and printing on one side of the partition paper so that it is easy to identify which part of the copy part separated by the inserted partition paper forms a part. It is to be. The printing of the partition paper is an easy-to-understand description such as the number of times of memory full and the number of the set, for example, as shown in FIG.
As shown in (1), printing such as “Memory full division 1 of 1” is performed at an easy-to-understand position on the partition paper (note that the printed content shown in this example is the first memory full and the first copy of the required number of copies. It is).

FIG. 6 is a flowchart showing an operation mode for inserting a partition sheet having one side printed at the end of a copy output of a read image when the memory is full. Referring to FIG. The operation will be described. This embodiment basically performs the same operation as that of the first embodiment, except that the above-described operation of printing on a partition sheet is added. Specifically, as shown in FIG. 6, it is checked whether or not printing of all the read originals has been completed (S5), and when the end is confirmed, the last copy of the original read up to the memory full is read. Insert the separator after the output, but
In this process, in the present embodiment, the above-described content is printed on one side of the inserted partition paper, and the printed partition paper is discharged after the last copy (S6-1), and this operation is repeated for all the copies. Then, one cycle of operation when the memory is full is completed. The printing and discharging operations in step S6-1 execute a job by adding a printing process to a partition sheet as part of an operation normally performed by the image forming apparatus in the partition sheet insertion mode. The present embodiment is the same as the first embodiment except for the operation related to the above-described printing on the partition paper, and therefore, will not be described repeatedly.

<Embodiment 3> In this embodiment, a partition sheet to be inserted into a break of each section is placed at the end of copy output every time printing of the first memory-full read image is completed.
In addition, printing is performed on one side of the partition paper so that it is easy to identify which part of the copy part separated by the partition paper forms, and the printing surface of the partition paper faces outward. Is to be discharged.

FIG. 7 shows the flow of the operation mode of this embodiment in which printing is performed on one side and a partition sheet that has been inverted and discharged is inserted at the end of a copy output of an image that has been read when the memory is full. The operation will be described with reference to FIG. This embodiment basically performs the same operation as the second embodiment,
The difference is that after printing, an operation of inverting and discharging the printed partition paper is added. More specifically, as shown in FIG. 7, printing of all the number of read originals is completed (S
5) The same content as in the second embodiment is printed on one side of the partition paper to be inserted after the copy (S6-2), and when the printed partition paper is discharged after the last copy, the partition paper is printed. Invert and discharge (S6-3). This reversal ejection is performed by reversing the part where the one-sided printing paper cut at the break of the copy part divided by memory full is usually (not reversed) overlaid after the copy body and the printed surface enters inside. Is to make the printing surface of the outside come out. Thus, the user can easily see the print content, and thus the unified operation of each section can be easily performed.

<Embodiment 4> In this embodiment, a partition paper to be cut into a set is inserted at the end of copy output every time printing of a memory-full image is completed. Printing is performed on both sides of the partition paper so that a part of the paper can be easily identified, and the paper is discharged.

FIG. 8 shows a flow of the operation mode of the present embodiment in which a partition paper having both sides printed is inserted at the end of a copy output of an image which has been read when the memory is full. The operation will be described. This embodiment basically performs the same operation as that of the second embodiment, except that an operation of printing on both sides is added when printing is performed. Specifically, as shown in FIG. 8, printing of the entire number of read originals is completed (S5), and the same content as in the second embodiment is printed on both sides of the partition inserted after the copy, and the printed image is printed. The partition paper is discharged following the last copy (S6-4). By printing on both sides of the partition paper, the copy of the text is selected on either one side or both sides and the process of making and processing the copy is different, and the effect may appear as a difference in the direction of discharging the partition paper. However, since the separating paper inserted after the text is non-directional, the printed surface always comes out and the user can easily see the printed contents, so the work of unifying the separated parts can be simplified. Easier to do.

<Embodiment 5> In this embodiment, the memory becomes full when a part of the original is read, and a break is made at the end of the copy when the operation is continued. In this embodiment, the memory becomes full. A partition sheet is inserted for each copy at the beginning of the next cycle after the printing of the image, so that copying by printing follows thereafter. FIG. 9 is a view for explaining the copy output state of this embodiment. This example is 5
In the case where three copies are made with one document, the copy partition mode is set, and the condition is such that memory full occurs with three documents. As shown in FIG. 9, in the first cycle, three copies of the original up to the third full memory are sorted and output in sets of three copies. After the interruption, a copy sheet is inserted at the beginning of the next cycle, and thereafter, a printing operation for the fourth document and thereafter is performed, and a total of [separator sheets + copy] 3 sheets are sorted into 3 copies for each copy. Is output.

FIG. 10 shows a flow of an operation mode in which a copy partition is inserted at the head of the next cycle after the memory full copy is completed. The operation of this embodiment will be described below with reference to FIG. . The user places a plurality of original bundles on the original platen 2, selects and sets copy conditions by operating keys on the operation unit (FIG. 2), and presses the print key 25 to start copying (S11). The manuscript is read by the reading unit 50, the image data is taken into the internal memory, a plurality of manuscripts are taken into the internal memory one after another, and when the memory capacity is full (memory full) (S12), once Since the intended copy cannot be obtained in the copy output process, the user is asked whether the user wants to continue the operation (S13).

When the user presses a key on the operation unit, for example, a copy partition mode key 24 prepared to perform the operation mode of the present flow, and requests the continuation of the operation, the originals up to the memory full which have been read into the internal memory are read. A printing process is performed using the image data (S14). It is checked whether printing of all the read originals has been completed (S15). If not completed, printing is repeated until all the read originals have been printed. After confirming all the completions, copying of the remaining originals is completed. The internal memory is cleared in order to perform the next cycle of (1) (S16).

The image of the next original (following the original printed by the memory full operation) is read into the empty internal memory (S17), and the next cycle of printing is started based on the newly read image. However, prior to printing, a copy separating sheet is inserted at the head of each section (S20). The following manuscript was read for insertion at the beginning of each part (S1
7) Later, it is determined whether or not the current step is a state where printing is completed (S18) and whether or not printing of the first document of each section is to be started (S19).
If it is determined in step S18 that printing has not been completed, it is determined whether or not the series of flows after reading the subsequent document in step S17 is the head of a set (S1).
9) If it is the top, a partition sheet is inserted (S20), and then printing processing is performed from the top original (S21). The second and subsequent originals are determined not to be the first original in step 19, and printing processing is performed one after another (S21). If it is determined in step S18 that printing has been completed, this cycle is terminated, the flow is returned to the initial state for the next cycle, and copy output processing from the start step (S11) of this flow is performed again on the remaining documents. Can be performed.

<Embodiment 6> In this embodiment, the memory becomes full when a part of the original is read, and a break is made at the end of the set when the operation is continued. In this embodiment, the memory becomes full. This is done by inserting a partition paper for each copy at the beginning of the next cycle after printing the image, and furthermore, it is possible to easily identify which part of the copy part separated by the inserted partition paper forms a part. The printing is performed on the partition paper, followed by the printing copy. The printing of the partition paper is an easy-to-understand description such as the number of memory full or the number of the set, etc., for example, as shown in FIG. 5, for example, as shown in FIG. Printing is performed (note that the printed content shown in this example is the first memory full and the required number of copies of the first copy).

FIG. 11 shows a flow of an operation mode in which a copy partition is inserted at the beginning of the next cycle every time printing of a memory-full image is completed. The operation of the present embodiment will be described below with reference to FIG. Will be described. This embodiment basically performs the same operation as that of the fifth embodiment, and is different in that the above-described operation of printing on a partition sheet is added. Specifically, FIG.
As shown in (2), before the printing process (S21) performed based on the image newly read after the memory is full, a copy partition is inserted at the beginning of each part. Printing is performed (S20-1). The means used for the printing and discharging steps on the partition paper is basically the same as that in the printing and discharging step of the second embodiment, and the same means can be used for the present embodiment.

<Embodiment 7> In this embodiment, the memory becomes full when a part of the original is read, and a break is made at the end of the set when the operation is continued. A partition sheet is inserted every time printing of a read image is completed, and a partition sheet is inserted for each copy at the beginning of the next cycle executed after clearing the memory from the memory full state. FIG. 12 is a view for explaining the copy output state of this embodiment. In this example, when three copies are made with five documents, the copy partition mode is set, and the conditions are such that memory full occurs with three documents. As shown in FIG. 12, in the first cycle, copy 3 of the original up to
The sheets are sorted and output in three copies for each copy, and a copy separating sheet is inserted at the end thereof, and a total of 4 copies of [copy + separating paper] are sorted and output for each copy. After the interruption, a copy sheet is inserted at the beginning of the next cycle, and thereafter, a printing operation for the fourth document and thereafter is performed, and a total of [separator sheets + copy] 3 sheets are sorted into 3 copies for each copy. Is output.

FIG. 13 shows a flow of an operation mode in which copy separation sheets are inserted at both breaks of a copy divided by memory full. The operation of the present embodiment will be described below with reference to FIG. I do. The flow shown in FIG. 13 is a combination of the flow of the first embodiment (FIG. 4) and the flow from step 17 to step 22 in the flow of the fifth embodiment (FIG. 10). That is, the first operation cycle when the memory is full is performed, and a partition sheet is inserted at the end of each section (S2).

[0037]

According to the present invention, the memory becomes full when a part of the original is read, and the stored image is first copied and output at this time, and the subsequent image is copied in the subsequent cycles. In the case of outputting, after inserting all the copy output by inserting a partition paper to be cut at the break of the cut copy at the end of the copy output in the preceding cycle and / or at the head of the copy output in the continuation cycle, the memory is not lost. Each part of the full and divided copy can be overlapped and unified, and the user can easily work and work efficiency is improved.

Further, by printing characters / symbols indicating which part of the copy is a part of the copy on the partition paper inserted at the break of the copy separated by the operation when the memory is full, the number of originals can be increased. Even if the number of copies and the number of copies increase (the number of copies and the number of divisions increase), and the work becomes complicated, it is possible to check the characters / symbols printed on the partition paper and copy the separated copies without fail. This makes it easy for the user to work and the burden is reduced. When printing characters / symbols on one side of the partition paper, the characters / symbols may not be visible depending on the output state.In this case, the reversed output will cause the printed surface to face outward. The above-mentioned effects are not impaired. Further, by performing double-sided printing, all output states can be handled.
