Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to easily set copy conditions for a plurality of original sets by stacking a plurality of original sets and specific format sheets such as mark sheets on an automatic original feeder. The present invention relates to a simple copying apparatus.

[0002]

2. Description of the Related Art In recent years, the copying function of a copying apparatus or an image forming apparatus provided with a copying apparatus has been increasing and becoming more complicated year by year. However, it has become difficult to understand how to obtain a desired copy result.

If the person who wants the copy result after copying is different from the operator who operates the copying apparatus, that is, if the person who wants the copy result verbally requests the operator to perform the copy by specifying the copy condition, Even if the copying conditions are communicated to the operator, errors in the various copying conditions (settings such as density, magnification, post-processing, double-sided copying, etc.) due to the misunderstanding of the operator or the transmission of incorrect copying conditions, etc. There is a problem that a size error or an excessive or insufficient number of copies is generated.

As a prior art for solving such a problem, Japanese Patent Laid-Open Publication No. Sho 59-121353 is known. According to the publication, a normal copying operation is performed in order to copy correctly based on desired copying conditions. An electrophotographic apparatus in which copy conditions are automatically set by placing a specific format sheet made of a mark sheet or the like in which copy conditions have been previously set and reading the copy conditions indicated on the specific format sheet by the apparatus itself. Is disclosed.

Another conventional technique is disclosed in Japanese Patent Application Laid-Open No. 9-18 / 1991.
No. 1893 discloses that a specific format sheet in which items based on the functions of the other party's facsimile apparatus are written in advance, together with the original, in the facsimile apparatus, and the copy mode of the receiving facsimile apparatus is set according to the functions of the receiving facsimile apparatus. To reduce the burden on the sender.

[0006] However, the above-mentioned publications are useful in that a single job can reduce the burden on the operator and prevent a transmission error or the like of a person who has requested the operator to perform copy processing. It is not possible to place and process each job continuously at one time, and it is necessary to place a set of specific format papers and originals on the device one by one for each job, and copy each set. There is a problem that processing the job is inefficient.

Therefore, Japanese Patent Application Laid-Open No. 63-96672 discloses that a plurality of sets of a specific format sheet and one or more originals on which copying conditions are marked are placed at once, and a job is set for each set by a copy start command. A technique has been proposed that can reduce the copying operation time of the copying machine and the operator restraining time even when a large number of jobs have to be processed by transferring to the tray and performing the copying operation. ing.

[0008]

However, the method described in Japanese Patent Application Laid-Open No. 63-96672 is characterized in that a plurality of sets of jobs can be processed at one time based on the copy conditions indicated on a mark sheet (specific format paper). Although it is useful, since the copying process is only performed in accordance with the copying conditions, there is a problem that the copying process cannot be continued, such as running out of paper, a problem that the copying conditions are inconsistent and the operation cannot be set, or a copying process is continued. Then, even if a trouble occurs in which copying conditions are set to a problem,
There is a problem that the copying process is continued.

Particularly, in the publication described in the publication, a plurality of sets of a document and a mark sheet are placed and subjected to a copying process.
If a problem occurs in the copying operation of the first set to be read and the device stops, the subsequent copying process cannot be continued, and the time required for the copying operation and the time required for operator restriction cannot be reduced. Alternatively, it is conceivable that the operator may be away from the apparatus due to performing a large number of sets of copying operations, and it may take a longer time to recover the apparatus, which may lower the operation rate of the apparatus.

For example, when the copying operation is performed on a plurality of sets, the number of remaining copy sheets is small, the number of copies of the first set to be copied first is large, and the number of copies of the second set and thereafter is small. A case where the entire set including the second and subsequent sets cannot be copied due to the large number of image forming sheets of the first set, even if the number of sheets that can be copied for the second set and subsequent sets is accumulated. Is also conceivable.

In addition, even if the copy conditions of the second and subsequent sets are normal and the copy processing is possible, if there is a contradiction in the copy conditions of the first set, the apparatus performs the copy processing of the first set at the stage of performing the copy processing. When the operation is stopped due to the abnormal state, the copy processing of the second and subsequent sets may not be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a method for copying a plurality of sets using a manuscript and a specific format sheet. Even if a trouble occurs in which copying cannot be performed in a set, a copying apparatus capable of avoiding a reduction in the operation rate (copying operation time) and a prolonged operator restraint time, and substantially improving the work efficiency. Is to provide.

[0013]

According to the present invention, at least one copy set consisting of an original and a specific format sheet on which copy information relating to the copy conditions of the original is recorded can be loaded, and the original of the copy set and the An automatic document feeder for transporting a specific format sheet one sheet at a time and discharging the same to the outside of the apparatus; a paper feeder for feeding the contained copy sheet; and a document image of the copy set transported by the automatic document feeder. Reading means for reading the copy information; and copy condition setting means for setting copy operations for the copy set based on the copy information read by the read means, based on the set copy conditions. A copying apparatus that copies an image corresponding to a document image onto a fed copy sheet and discharges the image to the outside of the apparatus. Comprising trouble detecting means for detecting a table, when it is trouble detected by said trouble detecting means, a copying apparatus, characterized in that the discharged without copying the document according to the copy group.

According to the above arrangement, when the operator sets a copy set including the specific format paper and the original corresponding thereto and presses the copy start button, the copying operation is performed in accordance with the copy conditions written on the specific format paper. Needless to say, even when a plurality of copy sets each including a specific format sheet and a document are set (placed) on the copy set, they are sequentially copied in accordance with each setting. In addition, even if the copy process instructed by the operator is exhausted during the copy operation and the copy process based on the current copy condition cannot be continued, the original document being processed is discharged without being copied. A new copy process can be performed from the next specific format paper (of course, if there is no final copy set, there is no subsequent copy set. Is completed).

According to the present invention, at least one copy set consisting of an original and a specific format sheet on which copy information relating to the copy conditions of the original is written can be loaded, and the original of the copy set and the specific format sheet can be stored in one copy. An automatic document feeder for transporting the sheets one by one and discharging the same to the outside of the apparatus; a paper feeder for feeding the contained copy paper; and a document image and the copy information of the copy set transported by the automatic document feeder. Reading means for reading, and copy condition setting means for setting a copy operation relating to the copy set based on the copy information read by the read means, based on the set copy conditions, A copying apparatus for copying an image corresponding to a document image and discharging the copied image to the outside of the apparatus; A trouble detecting means for detecting a trouble which can not, when it is trouble detected by said trouble detecting means, a copying apparatus, characterized in that the discharged without copying the document according to the copy group.

According to the above arrangement, the operator sets a copy set including a specific format sheet and a document corresponding to the specific format sheet, and presses a copy start button, whereby a copy operation is performed in accordance with the copy conditions written on the specific format sheet. Needless to say, even if a plurality of copy sets each including a specific format sheet and a document are set in the copy set, they are sequentially copied according to each setting. If the operation of the apparatus cannot be set based on the content described on the specific format paper, for example, “print darkly”, “print lightly”, “print with A3”, “print with B5”, etc. are performed at the same time. If the setting has been made, there is an idea that copying is performed using the default setting of the copying machine. However, it may be different from what the operator originally desires. Accordingly, an original for a specific format sheet on which such an ambiguous setting or an incorrect setting has been made can be discharged without copying, and the copying process can be continued (completed in the last set).

Further, according to the present invention, there is provided a paper remaining amount detecting means for detecting the remaining amount of paper stored in the paper feeding means, and information on the number of sheets corresponding to the number of sheets required for copying is written on the specific format sheet. A number calculating means for calculating the number of sheets required for copying based on the corresponding number information, and when the calculated number of sheets exceeds the remaining amount of paper, copying is performed on the document relating to the copy set. It may be configured to discharge without discharging.

For example, if the copying operation during processing is stopped after the paper is exhausted, there is a problem that the copying result is incomplete. However, according to the above configuration, the copying condition read from the specific format paper is not good. Based on, for example, it is possible to calculate how many copy sheets are required and compare with the remaining amount of copy sheets to determine whether or not the copy can be completed to the end before performing the copy, If not, the original is discharged without copying, and the copying process can be continued (completed if the last set).

Still further, according to the present invention, the paper feeding means can further contain and feed a second paper identifiable as a copy paper, and discharge the original of the copy set without performing copying. In such a case, the second sheet may be fed and discharged.

For example, when a plurality of sets including a specific format sheet and a set of originals are copied, even if a trouble occurs on the way, if the subsequent copy processing is continued, it is possible to determine where and how the original copy results. It is difficult to make a judgment, and in practice, the operation is performed by reading through all of the copy results, which leads to a decrease in work efficiency and a complicated work. However,
According to the above configuration, since the second sheet is inserted into the copy result and ejected, such complicated work can be avoided, and the separation work of the copy result performed by the operator can be simplified, and more quickly and reliably. It can be carried out.

An image processing unit 103, a laser writing unit 104 for forming an electrostatic latent image corresponding to an image on a photoconductive drum 105 by a laser beam, and a sheet for stacking sheets to be copied and transporting the sheets to form an image (copy) And a copy setting unit 107 as a copy condition setting unit for detecting a specific format sheet and setting the detected copy condition.

In the embodiment described above, the image forming system is an electrophotographic system using a photosensitive member and a laser, but the present invention is not limited to this. For example, as a light source, LED (Light Emittin
g Diode) or another image forming method such as an ink jet method or a thermal transfer method.

In this embodiment, the copying apparatus is a digital copying machine, and the reading means for reading the original image and the reading means for reading the copy conditions on the specific format paper are constituted by a single scanner unit. However, the present invention is not limited to this. For example, reading means may be separately provided for a document image and for a specific format sheet. Further, for example, if a reading unit and an image processing unit for reading a mark column described later of a specific format sheet are separately provided, the present invention is applicable even if the copying apparatus is an analog type.

Further, in the present embodiment, an example in which the present invention is applied to a digital copying machine is illustrated. However, the apparatus to which the present invention can be applied is not limited to this. Any device having a copy function capable of reading a format may be used. For example, the present invention can be applied to a facsimile, a multifunction printer, or the like having a copy function.

FIG. 1 shows an automatic document feeder,
Although the digital copier 1 integrally includes an image processing unit, a copy setting unit, an image forming unit, a paper feeding unit, and the like, a part or all of these components may be provided separately. The present invention can also be applied to a system in which image forming apparatuses such as an information processing apparatus such as a personal computer and a portable terminal, an external scanner equipped with an automatic document feeder, and a printer are interconnected.

(Description of Specific Format Sheet) FIG. 2 shows an example of a specific format sheet 200 inserted for each job in the document group 100 stacked on the automatic document feeder 101.

On the upper left side of the specific format sheet 200, the original to be read is a specific format sheet 20.
0 is provided, and the image processing unit 103 checks image data of a portion corresponding to the identification unit 201 in the read image data,
It is confirmed whether the read original is the specific format paper 200 or not.

On a specific format sheet 200, a document size identification unit 202 for designating the size of the original to be copied, the size of the paper to be copied, the copy density, the necessity of double-sided copying, etc., and the copy size identification Part 20
3. A density identification unit 204 and a double-sided copy identification unit 205 are provided. By applying a mark (mark) or the like to a desired portion of the corresponding identification unit on the specific format paper 200, copy conditions (copy information) can be set. It can be set easily and reliably.

In the document size identification section 202 or the copy size identification section 203, mark columns 202a to 202d and 203 are provided.
a to 203d are provided to mark which of A3, A4, B4, and B5 the document size or copy size is.

Similarly, the density discrimination section 204 is provided with mark columns 204a to 204c, which are marked as "dark", "normal", and "light", respectively. Columns 205a and 205b are provided to mark either "do" or "do not" for duplex copying, respectively.

In the present embodiment, the hatched mark columns 202b, 203b, 204b, and 205b are shown as being filled. In the case of FIG. 2, the document size and the copy size are A4, and the density is "A4". This indicates that the copying condition is “normal” and “not perform double-sided copying”.

As a method of designating in the mark field,
In addition to the case of filling as described above, 、, ×, a check mark, or the like may be added, or the end faces of the mark column may be connected by a line segment. In FIG. 2, the document size and the document size are “A3” to “B5”, the density is “high”,
Although the case where “normal”, “thin”, and “two-sided copy” is “yes” or “no” is illustrated, even if an identification unit or a mark field corresponding to other conditions is further provided or the arrangement is appropriately changed. It goes without saying that it is good.

FIG. 3 is a perspective view schematically showing a document group 100 in which only a plurality of sets each including the above-described specific format paper and a document corresponding to the specific format paper are placed. In the figure, black portions indicate specific format paper, and white portions indicate originals.

In this embodiment, the original group 100 is scanned by the automatic original feeder 101 from the lower side in FIG.
For example, the original corresponding to the specific format paper 301 is 302 to 305, the original corresponding to the specific format paper 306 is 307 to 311 and the original corresponding to the specific format paper 312 is 313. And originals are alternately stacked.

If the automatic document feeder is a trade-in type (a type that is conveyed from the lower side of the original group 301 to 313), even if the copy set is being conveyed, 313
By stacking a new copy set above the above, the copying operation can be continued.

(Explanation of Copying Operation) The contents of the operation when copying is performed using the above-described digital copying machine 1 and a specific format sheet will be described below.

The document group 100 is stacked on an automatic document feeder 101 as shown in FIG. 2, and is sequentially conveyed to the scanner unit 102 from the lowest sheet (document or specific format sheet). The read image data is sent to the identification unit 20 by the copy setting unit 107.
By checking the image data corresponding to No. 1, it is determined whether the conveyed sheet is a document or a specific format sheet.

If it is determined that the sheet is of a specific format, copying conditions are set in accordance with the mark given by the operator, and it is not necessary to copy the specific format itself.
And is discharged out of the apparatus.

On the other hand, if the copy setting unit 107 determines that the original is not a specific format paper but an original, the image processing unit 10 according to the conditions set in advance in the specific format.
In step 3, image processing of the image data is performed, and an electrostatic latent image corresponding to the document image is formed on the photoconductor 105 via the laser writing unit 104.

The electrostatic latent image formed on the photoreceptor 105 by laser irradiation is visualized by a developing device (not shown), and the latent image is formed on a sheet fed from a paper feeding unit 106 by a transfer device (not shown). Is transferred, is permanently visible by a fixing device (not shown), and is discharged from the outside of the device.
The document after the copy processing is discharged from the scanner unit 102 by the automatic document feeder 101.

(Explanation of Main Flowchart) Processing contents according to the embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a main flowchart in this embodiment, and FIG. 5 is a document size setting portion (subroutine).
6 is a flowchart of a copy size setting portion, FIG. 7 is a flowchart of a density setting portion, and FIG. 8 is a flowchart of a duplex copy setting portion.

In FIG. 4, first, an image data area corresponding to an identification section for identifying a specific format sheet 200 is read from the image data being read (step S10, hereinafter abbreviated as S10). If the sheet currently being read has no identification section (no identification section) and is not a specific format sheet, the image processing section 1
When 03 is determined (N in S11), normal image processing or image forming operation is performed without performing special processing.

On the other hand, when the image processing unit 103 determines that the image data being read is a specific format sheet (Y in S11), the original size setting subroutine (S12) and the copy size setting subroutine (S1)
3) A density setting subroutine (S14) and a duplex copy setting subroutine (S15) are sequentially processed.

(Explanation of Each Subroutine) FIG. 5 shows a flow corresponding to the subroutine S12 for setting the document size.
In FIG. 5, the image data area corresponding to the document size identification unit 202 of the specific format paper 200 is read (S20), and in S21, the image processing unit 103 obtains the number of mark locations.

For example, when there are a plurality of mark locations (in the case of "plural" in S21), it is unreasonable that the document size is a plurality of types. Go to. When the number of mark locations is 0 (in the case where no mark is detected and “0” in S21), the document size detecting means (not shown) provided on the Is automatically set (S24).

On the other hand, if there is only one mark location (one in S21), the document size is set depending on which of the mark columns 202a to 202d has the document size mark. That is, when the document size is described in the mark column 202b, the document size is determined to be A4, and the document size is set to A4 (S27). Similarly, when the document sizes are A3, B4, and B5, the same processing is performed, and the document size is set (S25, S26, S28).

FIG. 6 shows a copy size setting subroutine S.
13 shows a flow corresponding to FIG. 5, and reads an image data area corresponding to the copy size identification unit 203 of the specific format paper 200 in the same manner as in FIG.
0), in S31, the image processing unit 103 obtains the number of mark locations.

For example, when there are a plurality of mark locations (in the case of "plural" in S31), it is unreasonable that the copy size is a plurality of types. Go to. If the number of mark locations is 0 (when no mark is detected and “0” in S31), the document size is determined based on the result of the document size detection means, the document size and the copy magnification set in FIG. The copy size is automatically set to match (S3
4).

On the other hand, if there is only one mark location (one in S31), the copy size is set depending on which of the mark columns 203a to 203d has the copy size mark. That is, if it is described in the mark column 203b, the copy size is determined to be A4, and the copy size is set to A4 (S37). Similarly,
The same processing is performed when the copy size is A3, B4, or B5, and the copy size is set (S35, S36, S5).
38).

FIG. 7 shows a flow corresponding to the density setting subroutine S14. The flowchart corresponds to the density identification section 204 of the specific format paper 200 in the same manner as in FIGS. There are two modes: setting of a mode (photo mode, manual mode, automatic mode) and setting of density levels (density levels 1 to 5). Note that the density identification unit in FIG. 2 illustrates the specific format paper 200 set in three levels of “dark”, “normal”, and “light”. A density mode and five levels of density can be set.

First, the image processing section 103 reads an image data area corresponding to the density mode setting section 204 (S40), and determines in S41 how many mark locations exist. For example, when there are a plurality of mark locations (S4
In the case of “multiple” in 1), there are a plurality of types of density modes, which is irrational, so that an error notification is given to the user by display or voice in S48. When the number of mark locations is 0 (in the case where a mark is not detected and “0” is determined in S41), in the present embodiment, an error notification is similarly performed in S48 (the number of mark locations is 0). In the case of, an automatic mode may be configured).

On the other hand, if there is only one mark location (one in S41), the photographic mode setting (S43) depends on which of the mark columns (not shown) indicates the density mode mark. (S44), one of the automatic modes (S45) is set. If the density mode is the automatic mode, the process returns because the density level described below is meaningless.

On the other hand, if the mode is the photograph mode or the manual mode, the processing shifts to S46, and similarly, marks of five levels of density level setting sections (not shown) are read, and
In step 7, the number of the marked portions is determined. For example,
When there are a plurality of mark locations (in the case of "plural" in S41)
Alternatively, when the number of mark locations is 0 (when a mark cannot be detected and “0” in S41), there are a plurality of types of density levels, which is unreasonable. To the user.

On the other hand, when there is one mark portion (one in S47), the density level 1 (S50) and the density level are determined depending on which of the mark columns (not shown) indicates the density level mark. 2 (S53), density level 3
(S51), density level 4 (S54), density level 5
(S52) is set.

FIG. 8 shows a subroutine S1 for setting double-sided copy.
5 shows a flow corresponding to FIG. 5, and similarly to FIGS. 5 to 8, the image processing unit 103 reads the image data area corresponding to the double-sided copy identification unit 205 of the specific format paper 200 (S60), and S61. Ask how many mark locations there are.

For example, when there are a plurality of mark locations (in the case of “plurality” in S61) or when there are 0 mark locations (in the case where no mark is detected and “0” in S61),
Since the setting of the two-sided copy is unreasonable, the user is notified of an error by display, voice, or the like in S62.

On the other hand, if there is only one mark location (one in S61), the mode of double-sided copy is set according to which of the mark fields 205a or 205b has the mark for double-sided copy. That is, the mark column 203
In the case of “b”, it is determined that “two-sided copy is not performed” (S65).
Is determined (S64).

The error notification (S62) will now be described. For example, the double-sided copy identification unit 205 in FIG.
If there is a mark in the mark column 205a, double-sided copy is performed. If there is a mark in the mark column 205b, double-sided copy is not performed.
("Never"),
Alternatively, if both are not marked, the apparatus cannot determine whether or not to perform double-sided copy as a copy process, and cannot appropriately set the operation of the apparatus.

Therefore, at the time of error notification (S46), the error information is transmitted to the document feeder control unit 50 by the specific format sheet detection unit and the copy setting unit 503 described later with reference to FIG.
1 and thereafter the document is discharged until the next specific format sheet is detected. Here, the setting portion of the two-sided copy has been described, but it goes without saying that other setting items such as the document size, the copy size, and the density can be similarly processed.

(Explanation of Operation During Copy Trouble) As an example of a copy trouble, a case where the copy paper runs out during copying will be described with reference to the block diagram of FIG. When the automatic document feeder 101 is controlled by the automatic document feeder controller 501 and a specific format sheet is conveyed from the document group 100, image information is read by a document reader 502 provided in the scanner unit 102, and the image is read. The copy size is set by the specific format sheet detection unit and the copy setting unit 503 provided in the processing unit 103 and / or the copy setting unit 107.

Next, the copy size information is sent to a paper feed control unit 504 for controlling the paper feed unit 106. When the paper of the set copy size remains, the paper feed control unit 504 sends the above described feed size information. Only the paper processing is performed.
When an out-of-paper detecting unit (not shown) provided in the printer detects out-of-paper, the out-of-paper information is sent to the automatic document feeder control unit 501.

The automatic document feeder control unit 501, which has received the out-of-paper information, detects a specific format sheet from the image information read by the document reading unit 502 until the next specific format sheet is detected. Until a specific format sheet is detected by the copy and copy setting unit 503, the reading of the original image and the discharging of the original document are repeated.

More specifically, the originals 302 and 30 are copied in accordance with the copy conditions described on the specific format sheet 301 in FIG.
When the out-of-paper information is detected at the end of the copy of No. 3,
Originals 304 and 305 are ejected without being copied,
When the next specific format sheet 306 is detected, new copy conditions are set, and when it is determined that copy processing is possible with the remaining sheets, copy processing is restarted from the original 307.

If it is determined that the paper of the copy size designated by the specific format paper 306 is out of paper in view of the copy conditions, the next specific format paper 306
It goes without saying that up to 12 originals are discharged without being copied.

In the above embodiment, there are a plurality of developers (toners, inks, etc.), and multiple colors (including full colors).
Although no particular description is given of the case of forming an image by using the image forming apparatus, the image forming apparatus (digital copying machine) may be capable of forming a multicolor image. In this case, although not shown in FIG. 2, an identification unit for identifying a monochrome image (when forming an image with a single color such as black) and a multicolor image (when forming an image with two or more colors) is provided. A mark column is provided.

Therefore, for example, when the developer other than black is exhausted, a multicolor image cannot be formed, but the subsequent set is an image formation using only the black developer (the mark column corresponding to the monochrome image is not displayed). If the mark is marked), the original relating to the previous multi-color image and the specific format paper may be discharged, and the subsequent sets may continue to form images. As a result, it is possible to prevent a decrease in the operation rate of the apparatus without hindering image formation of a subsequent monochrome document.

(Other Embodiments) In the above embodiment,
There may be cases where the copying is stopped in the middle of the copying process and the process cannot be completed. Other embodiments corresponding to this may be described in detail below.

Although not shown, in the specific format sheet shown in FIG. 2, the corresponding number information includes "number of originals", "number of copies (how many copies are made per original)", and "2in".
A mark field such as "1 copy (copy two originals on one sheet)" is further provided, and the processing block shown in FIG. 10 is added to the specific format sheet detection section and copy setting section 503.

In FIG. 10, the number of originals and the number of copies are multiplied by a multiplier 601 serving as a number calculating means, and the result and the value of 1/2 obtained by the divider 602 are "do" or "do" for double-sided copying. No, the selector 603 selects the required number of copy sheets and the remaining amount of sheets obtained from the sheet feed control unit 504. If it is determined that all copy processing cannot be performed, error information is output. To the automatic document feeder controller 501. Thereafter, in the same manner, until the next specific format paper is detected,
By discharging the document, it is possible to suppress unnecessary decrease in the operation rate due to trouble.

In the above description, the calculation of the necessary copy paper is described. However, the present invention is not limited to this, and the information of the copy paper required for the specific format paper itself is stored. Of course, it may be configured to be able to mark.

(Other Embodiments) In this embodiment, in order to easily distinguish the jobs of each copy set, a "bookmark sheet", which is a second sheet that can be identified as a copy sheet, is used.
Therefore, the paper feeding unit 106 further includes a paper feeding unit for storing and feeding the second paper in addition to the copy paper.

That is, sheets that can be distinguished from normal copy sheets are stored (stacked) in at least one of the sheet feeding units 106 shown in FIG. Here, as described above, when it becomes impossible to continue the copying process from the beginning or in the middle of the copying process, the error information is sent to the image storage unit 701 and the paper feeding unit 702 as shown in FIG. . At this time, the image storage unit outputs image information corresponding to the error information, and the information is formed on the “bookmark paper” fed from the paper feeding unit 702.

The above-mentioned “bookmark paper” may be any paper that can be distinguished from the paper to be copied. For example, a colored paper (a paper whose background color is other than white) or a paper (material , Materials and paper thicknesses, etc.), and especially if the paper is colored, the operator can easily recognize it.

The above processing may be performed not only at the time of error termination but also at the time of normal processing. Further, the image information is not stored in the image storage unit 701 or only a part of the image information is stored. The "paper" can be reused, and the error information can be simply displayed on the display unit or the like of the digital copying machine 1.

According to the present invention, the operator sets a copy set including a specific format sheet and a document corresponding to the specific format sheet, and presses a copy start button, whereby a copy operation is performed in accordance with the copy conditions written on the specific format sheet. Needless to say, even when a plurality of copy sets each including a specific format sheet and a document are set in the copy set, they can be sequentially copied according to each setting.

Also, even if the copy process based on the current copy conditions cannot be continued, for example, when the copy sheet specified by the operator runs out during the copy operation, the original document being processed is discharged without being copied. Thus, a new copy process can be performed from the next specific format sheet.

Therefore, the copying process of a plurality of sets composed of the original and the specific format paper can be efficiently performed, and even if a trouble occurs, the copying process can be continuously performed, thereby substantially reducing the copying operation time and the operator restraining time. Therefore, there is an effect that it is possible to suppress a decrease in operation efficiency and a decrease in work efficiency due to delay of a subsequent copy process.

Further, according to the present invention, the operator sets a copy set including a specific format sheet and a document corresponding to the specific format sheet, and presses a copy start button, whereby a copy operation is performed in accordance with the copy conditions described on the specific format sheet. Needless to say, even when a plurality of copy sets each including a specific format sheet and a document are set in the copy set, they are sequentially copied according to each setting.

If the setting of the apparatus cannot be set with the contents described on the specific format paper because the setting is ambiguous or wrong, for example, "print darkly"
If “Print lightly”, “Print with A3”, “Print with B5”, etc. are set at the same time, the original for the specific format paper is ejected without copying, and the next specific format paper is output. A new copy set composed of a manuscript can be copied, and a new copy process can be performed from the next specific format sheet.

Accordingly, the copying process of a plurality of sets composed of the original and the specific format paper can be efficiently performed, and even if a trouble occurs, the copying process can be continuously performed, thereby substantially reducing the copying operation time and the operator restraining time. It is possible to reduce the operating efficiency and the work efficiency due to the delay of the subsequent copying process.

Here, for example, after the paper runs out,
There is a problem that if the copying operation during processing is stopped, the copying result is incomplete, but according to the present invention, it is possible to determine beforehand whether or not copying can be completed to the end before copying. Since the copy set can be skipped and the copy operation of the subsequent copy set can be continued, it is possible to suppress a decrease in operation efficiency and a decrease in work efficiency due to a delay in the subsequent copy processing.

Further, for example, when a plurality of sets including a specific format sheet and a set of originals are copied, even if a trouble occurs on the way, if the subsequent copy processing is continued, the copy result of which original is obtained is obtained. Is difficult to determine, and in practice, this is done by the operator looking through all of the copy results, which not only complicates the work but also significantly impairs the work efficiency.

However, according to the present invention, since the second sheet is inserted into the copy result and ejected, such complicated work can be avoided, and the separation work of the copy result performed by the operator can be simplified. Further, it can be performed quickly and reliably.
