Abstract

PROBLEM TO BE SOLVED: To continue a total page number printing mode processing without canceling a total page number printing mode even when a storage means has no remaining amount in the process when an original image is read, while counting the original page number in this mode. SOLUTION: When a storage means has no remaining amount in the process when an original image is read, while counting a original page number in a total page number printing mode, the effect that the total page number should be inputted is urged by a notification input means and the input of the total page number as it is possible by an input screen 57. Thus, a user is required to only perform the counting of the original page number and the input of the total page number, and the total page number an be acquired even when the counting by a counting means is interrupted in the process. Therefore, a paging printing accompanying the total page number for the image information stored in the storage means becomes possible.

Description

Detailed Description of the Invention

[0001]

The present invention relates to an image forming apparatus such as a digital copying machine and a facsimile.

[0002]

2. Description of the Related Art In recent years, high-grade and diversified functions of image forming apparatuses of this type have been advanced. One of such functions is a pagination function of combining page information with an output image and performing additional printing on a transfer paper, which is executed by an additional printing unit. Further, as another function, there is one having a so-called electronic sort function of temporarily storing a plurality of document images in the image memory and outputting the document image image data stored in the image memory in the order of pages.

As such a pagination function, in addition to a simple pagination mode in which only the number of pages is printed, a mode in which pagination is performed in the form of (the number of relevant pages) / (total number of pages) In the specification, there is a "total page print mode"). According to this total page printing mode, not only the number of corresponding pages but also the total number of pages can be always grasped, which is convenient for some purposes. When printing is performed by designating the total page print mode, it is necessary to know the total number of pages. Generally, the user is made to input the total number of pages of the document to be printed, but this method is troublesome because the user must always count the total number of pages of the document. Therefore, focusing on the counting function of the automatic document feeder, the original image is read while counting the number of originals (original pages) when the originals are fed by the automatic document feeder, and the image information is sequentially stored in the image memory. When the reading of all originals is completed, the total number of pages is known. Therefore, there is a method in which the image information stored in the image memory is sequentially paged and printed using the total number of pages. According to this, the user only needs to stack and set a plurality of documents on the automatic document feeder and give a start instruction, so that the printed matter in the total page print mode can be obtained without trouble.

[0004]

However, since the image memory has a finite capacity, when the image information is sequentially stored as the original image is read, the image is read even if the original to be read still remains. The memory may become full. Therefore, when such a situation occurs in the total page number print mode, the number of original pages is being counted and the total page number cannot be known. Therefore, the function of the total page number print mode must be canceled. I won't get it.
This results in a total page number print mode with many restrictions, such as wasted reading operations. However,
It is sufficient to set the image memory capacity to a huge memory capacity, but the cost becomes extremely high.

[0005]

According to a first aspect of the present invention, a reading unit that reads an original image, a storage unit that stores the image information read by the reading unit, and image information of the original on the transfer paper are stored. In addition, additional printing means for synthesizing and printing page information, counting means for counting the number of original pages before and after the reading operation by the reading means, and residual quantity detecting means for detecting the residual quantity of the storage means, A mode designating unit that designates a total page printing mode in which the additional printing unit prints the page information in a fractional form with a total number of pages as a denominator, and the reading when the total page printing mode is designated by the mode designating unit. When the remaining amount detecting unit detects that the remaining amount in the storage unit is low when the document image is read by the unit, the reading operation by the reading unit is interrupted. That reading interruption means, and, and a notification input means for prompting the Operator to enter the total number of pages with an input screen for inputting the total number of pages of the document.

Therefore, when the total page number print mode is designated by the mode designating means, the document image is read by the reading means while counting the number of document pages by the counting means, and the image information is sequentially stored in the storing means. When the reading of the document is completed, the number of document pages counted by the counting means is taken as the total number of pages, and the total number of pages is used as a part of the page information and the image information stored in the image memory is sequentially processed by the additional printing means. It is printed with pages. When the reading means detects that there is no remaining amount in the storage means when reading the original image, the reading interruption means interrupts the reading operation, and the notification input means prompts the user to input the total number of pages. Since the total number of pages can be input as it is, the user only needs to input the total number of pages by counting the number of pages of the manuscript. Even if the counting by the counting means is interrupted midway, the total number of pages can be input. Therefore, it is possible to perform pagination printing with the total number of pages regarding the image information stored in the storage means. As a result, even if the storage means with a finite capacity becomes full on the way, the function of the total page number printing mode can be executed by the user's input operation without canceling the function of the total page number print mode on the way.

According to a second aspect of the invention, instead of the notification inputting means in the first aspect of the invention, the remaining not read by the reading means is accompanied by an input screen for inputting the number of remaining original pages. A notification input unit is provided for urging the user to input the number of manuscript pages. Therefore, claim 1
As in the case of the invention described above, even if the storage means with a finite capacity becomes full on the way, it can be executed by a combination of user input operations without canceling the function of the total page number print mode on the way. Since the notification input means prompts the user to input the remaining number of original pages that have not been read by the reading means and inputs the number of original pages, the number of original pages to be counted by the user is minimized and the burden on the user is reduced. It gets lighter.

According to a third aspect of the present invention, with respect to the second aspect of the invention, the reading means has an intermediate conveyance path for conveying the original in the vicinity of the image reading position, and has a function of preliminarily feeding the next original. An automatic document feeder is provided, and when the remaining amount detecting unit detects that there is no remaining amount in the storage unit when the document image is read by the reading unit when the total page print mode is designated by the mode designating unit, the automatic document source is used. It has a preliminary feeding control means for stopping the preliminary feeding of the next document in the conveying device.

Therefore, in the case of an automatic document feeder having a function of preliminarily feeding a document, the next document is sent to the intermediate transport path when reading the document in order to shorten the document transport time. When the user counts and inputs the number of remaining document pages when the storage means is full during scanning, the number of document pages that have not yet been read is counted if there are documents that have been sent to the intermediate transport path. There is a high possibility that counting errors will occur, and the total number of pages will be incorrect, but since the preliminary feeding is stopped by the preliminary feeding control means at the time when the remaining amount in the storage means is detected, the existence of unread documents becomes clear. The numbering error is reduced, and the pagination printing can be performed under the correct total number of pages.

The exposure lamp 5 and the first mirror 6 are mounted on a first carriage (not shown), and the second and third mirrors 7 and 8 are mounted on a second carriage (not shown). The first carriage and the second carriage are mechanically scanned in the same direction at a speed ratio of 2: 1 so that the optical path length does not change. The first and second carriages are driven by a scanner drive motor (not shown). The original image on the contact glass 3 is read and scanned by the scanning optical system 4 to form a reduced image on the CCD 10 and is read so as to be an electric signal through a photoelectric conversion process.

An automatic document feeder (ADF) 11 is mounted on the contact glass 3 of the reading unit 1. The ADF 11 includes a document table 12, a paper feed roller 13, a paper feed / conveyance belt 14 located on the contact glass 3, a paper discharge roller 15, and a document discharge tray 16. A document set detection sensor 17 is provided near the entrance of the document table 12. As a result, when the print key on the operation unit, which will be described later, is pressed, the stack of documents stacked on the document table 12 with the image surface facing upward starts from the lowest document and is fed by the paper feed roller 13 and the paper feed conveyor belt 14. Thus, the paper is fed to a predetermined position on the contact glass 3 and stopped. At this time, it has a function of a counting unit that counts the number of documents each time the documents are fed and conveyed. Documents fed and fed onto the contact glass 3 are read by the reading unit 1.
When the reading is completed after being read by the paper, the document discharge tray 1 is driven by the paper feeding / conveying belt 14 and the discharge rollers 15.
6 is ejected onto the sheet. At this time, the document set detection sensor 17
If the following original document is detected by, the original document on the original table 12 is fed and conveyed onto the contact glass 3 as in the case of the preceding original document. The sheet feeding roller 13, the sheet feeding / conveying belt 14 and the sheet discharging roller 15 in the ADF 11 are driven by a conveying motor described later.

Next, the image forming unit 2 will be described.
The image forming unit 2 has a drum-shaped photoconductor 21 as a center, and the electrophotographic process is performed around the photoconductor 21 according to an electrophotographic process.
It is configured by sequentially arranging process members and means such as a charging charger (not shown), a writing unit 22, a developing device 23, and a transfer charger (not shown).
The writing unit 22 is configured as a laser writing optical system including a laser output unit (including a laser diode, a polygon mirror, etc.) 24, an imaging lens 25, a mirror 26, and the like.

Further, on the lower side of the image forming unit 2, the first to third trays 28 to 3 each containing the transfer paper 27 are accommodated.
0 is detachably mounted. First to third sheet feeding devices 31 to 33 are provided on the sheet feeding side of each of the trays 28 to 30, and the photosensitive members 21 through a common vertical conveyance unit 34.
The transfer paper 27 can be fed and conveyed to the transfer position side of. Further, a transport belt 35, a fixing device 36, a paper discharge unit 38 including a paper discharge roller 37, and a paper discharge tray 39 are sequentially provided downstream of the transfer position of the photoconductor 21 in the transport direction. A double-sided paper feeding unit 41 including a double-sided tray 40 is disposed above the first tray 28. In the paper discharging unit 38, a transfer path of the transfer paper 27 is connected to the paper discharging tray 39 side. A switching claw 42 for switching between the two-sided tray 40 side is provided. The re-feed side of the double-sided sheet feeding unit 41 communicates with the vertical conveyance unit 34.

As a result, the transfer sheets 27 stored in the first to third trays 28 to 30 are transferred to the first to third sheet feeding devices 31 to 33.
, And is transported by the vertical transport unit 34 to the transfer position of the photoconductor 21. On the other hand, photoconductor 2
On the first side, an electrostatic latent image is formed by the optical writing by the writing unit 22, and a toner image is formed by the development by the developing device 23. The transfer paper 27 transported by the vertical transport device 34 is transported by a transport belt 35 driven at the same speed as the photosensitive member 21 while being synchronized with the leading end of the toner image, and receives the transfer of the toner image. The transfer paper 27 after the transfer is fixed by the fixing device 36 and then discharged onto a discharge tray 39 by a discharge roller 37.

Here, after the front side copy in the double-sided copy mode is completed, the switching claw 42 is switched and the transfer paper 27 is temporarily discharged to the double-sided tray 40 side for copying on the back side. To be re-fed.

Next, the structure of the operation unit 51 will be described with reference to FIG. The operation unit 51 includes a print key 52, a numeric keypad 53, a clear stop key 54, and an initial setting key 5.
5, equipped with keys such as the mode clear key 56,
A liquid crystal touch panel 57 is provided. The liquid crystal touch panel 57 has an input operation unit 59 including a function key 58 that appears as appropriate for each screen, and a display unit 60 that displays a message indicating the number of copies, device status, and the like.

FIG. 4 shows a display example of the basic screen of the liquid crystal touch panel 57. As shown in the illustrated example, the liquid crystal touch panel 57
On the basic screen of, "Double-sided setting key""Aggregation setting key"
A function key 58 such as a "page print setting key" appears.
As for the function key 58, when the key function display portion is pressed, the key portion is inverted to black. The example shown is
The state where the “A4 horizontal selection key” indicating the feeding of the transfer paper from the first tray 28 is pressed is shown. Further, when the details of the function have to be specified (for example, content setting in the aggregation mode), pressing the corresponding key function display portion displays the detailed function setting screen as described later. . In any case, since the liquid crystal touch panel 57 uses the dot display, the optimal display at that time can be graphically performed.

Next, the hardware configuration of the electrical equipment control system will be described with reference to FIG. An IPU (image processing unit = image processing unit) 62 is connected to the main controller 61 for controlling the entire digital copying machine in addition to the operation unit 51 and the ADF 11. The distributed controllers 51, 11, and 62 and the main controller 61 exchange machine status, operation commands, and the like as necessary. Here, a transport motor 63 for driving the paper feed roller 13 and the like is connected to the ADF 11. Further, the main controller 61 is connected to a main motor 64 and various clutches 65 to 68 necessary for transporting the transfer paper. The main motor 64 is for driving the photoconductor 21, the developing device 23, the transport belt 35, the fixing device 36, the paper discharge unit 38, and the like. The driving of the main motor 64 is transmitted to the respective sheet feeding devices 31 to 33 via the sheet feeding clutches 66 to 68, respectively. The vertical transport unit 34 is driven by the main motor 64 to drive the intermediate clutch 65.
Is transmitted and transmitted via the

FIG. 6 shows the internal structure of the IPU 62. The IPU 62 is provided with a CPU 71 for controlling the reading unit 1 and the writing unit 22 described above. The CPU 71 is connected via a bus line to a ROM 72 storing a control program and the like, a RAM 73 storing various data, an I / O port 74, and an image memory controller 75. An image memory 76 serving as a storage unit is connected to the image memory controller 75. Thereby, the CPU
Reference numeral 71 is capable of writing data to the image memory 76 and reading data from the image memory 76 via the image memory controller 75.

On the other hand, the CCD 10 in the reading unit 1,
An A / D converter 77, a shading correction circuit 78, an MTF & γ correction circuit 79,
A selector 80 and a scaling circuit 81 are connected in order. As a result, the information of the document image photoelectrically converted and read by the CCD 10 is converted into a digital signal by the A / D converter 77, the shading correction circuit 78 receives the shading correction, and the MTF & γ correction circuit 79 receives the MTF correction and the γ correction. Input to the selector 80. The selector 80 switches the destination of the image data between the scaling circuit 81 and the image memory controller 75. When the magnification circuit 81 is selected by the selector 80, the image data undergoes enlargement / reduction processing in accordance with the magnification in the magnification circuit 81, and is then sent to the writing unit 22, where the image data is actually processed. For writing. Further, the selector 80 and the image memory controller 7
Image data can be input / output bidirectionally between the input and output terminals.

When the image memory controller 75 side is selected by the selector 80, the image data is compressed by the image compression circuit in the image memory controller 75 and then written in the image memory 76. Here, it is possible to write the data of 256 gradations corresponding to the maximum original size to the image memory 76 as it is, but it is limited to avoid consuming a large amount of the capacity of the image memory 76 for one original image. In order to effectively use the above memory capacity, the image is compressed and then written in the image memory 76.

Since the image memory 76 can store a large amount of original image data at a time, it has a function of outputting the image data of the original images stored in the image memory 76 in page order. When an image is output by this function, the image data in the image memory 76 is output to the writing unit 22 side while being sequentially expanded by an image expansion circuit in the image memory controller 75.
Such a function is generally called "electronic sort".

Further, by utilizing such characteristics of the image memory 76, it is possible to sequentially read a plurality of original images into divided areas obtained by dividing an area of one surface of the transfer paper in the image memory 76. It also has an image aggregation function using. For example, four original images are stored in the image memory 76.
By sequentially writing the area of one transfer sheet inside into four divided areas, the four original images become one transfer sheet 2.
7 can be obtained. Such a function is generally called "aggregate copy". Here, in the present embodiment, as the aggregation mode, “page order aggregation mode” and “book type aggregation mode” according to the electronic sort function are provided so as to be selectable, and when each mode is selected, The page order image collecting means and the book-type image collecting means are executed respectively.

A print unit 82 is provided which is connected to the CPU 71 via a bus line and generates print image data. The printing unit 82 functions as an additional printing means and generates a character image for printing page information, an arbitrary stamp image, and the like. The image image data generated by the printing unit 82 is input to the print synthesis 1 circuit 83 and the print synthesis 2 circuit 84, and an arbitrary image is formed with respect to the image from the original image or the image read from the image memory 76. It is configured so that it can be synthesized. When the image image data from the printing unit 82 is combined by the print combining 1 circuit 83, the image data read from the reading unit 1 (CCD 10) can be combined and printed, and the image from the printing unit 82 is formed by the print combining 2 circuit 84. When the image data is combined, the image data from the image memory 76 can be combined and printed. Further, the printing unit 82 not only outputs the image image data to be combined, but also sets the position of the generated image data to be combined with the original image data and the image data from the image memory 76. I also own.

The image signal for one page in the selector 80 will be described with reference to FIG. The frame gate signal / FGATE is an effective period of one page of image data in the sub-scanning direction. The main scanning synchronization signal / LSYNC for each line makes the image signal valid at a predetermined clock (8 clocks in the illustrated example) after this signal rises, and the line gate signal / LGATE falls. These signals are synchronized with the pixel clock VCLK, and one pixel 8 per one cycle of the pixel clock VCLK.
Bit (= 256 gradation) data is sent. In this embodiment, the writing density on the transfer paper 27 is 400 dpi, and the maximum number of pixels is 4800 pixels in the main scanning direction and 68 pixels in the sub-scanning direction.
00 pixels.

FIG. 8 shows a structural example of the printing unit 82. The printing unit 82 includes a character set ROM 86 and a flash memory 87 with a print data generating gate array 85 as a center. The character set ROM 86 stores character image data such as letters, numbers, and Chinese characters up to JIS level 2, and the flash memory 87 stores arbitrary image data. The print data generation gate array 85 has a pixel clock VCLK as an image timing signal,
Frame gate signal / FGATE, main scanning sync signal / L
SYNC is given, and the print image data created in synchronization with these signals is output to the print synthesis 1 circuit 83 or the print synthesis 2 circuit 84.

Therefore, the data of various registers of the print data generating gate array 85 is set by the operator from the CPU 71 via the bus line. The types of registers that can be set include: character print mode, arbitrary image data print mode, print data, print start position address, X coordinate, Y coordinate.

The page printing will be described below. For page printing, when the page printing mode is selected by pressing the “page printing key” on the basic screen of the liquid crystal touch panel 57 shown in FIG. 4, a format screen as shown in FIG. 38 appears and the page printing mode is changed. It becomes selectable.
"P1, P2, ..." are for selecting the normal page print mode,
"1/5, 2/5, ..." are function keys 58 for selecting the total page print mode, and function as mode designating means. Further, in this format screen, a "page allocation key" for selecting how to perform page allocation appears as a function key 58 as described later.

In any case, when the operator selects the page print mode through the format screen as shown in FIG. 38 and presses the print key 52, data is set in the register of the print data generating gate array 85. For example, as shown in FIG. 9, when printing “1/10” at a position 20 mm from the right end surface of the transfer paper 27 and 10 mm from the upper end surface in the total page print mode, the print data generation gate array 85 Set the "character print mode" of the register. After that, as the print data, as the character shift JIS code, 1 (825
Set 0), / (815E), 1 (8250), 0 (824F). Further, as the print start position address is 63 μ per pixel clock VCLK, data 318 is set as 20 mm in the X direction and 159 is set as 10 mm in the Y direction. When the data set in the register is completed, the print data generation gate array 85 is in the character print mode. Therefore, the character set ROM 86 is accessed and the designated character image data is RO
Read out from M data.

On the other hand, a counter for counting the number of falling times of the main scanning synchronization signal / LSYNC, a comparison circuit for comparing the print position Y data (here, data of 159), and a falling edge of the frame gate signal / FGATE. A counter that counts the pixel clock VCLK and a comparison circuit that compares the print position X data (here, data of 318) operate. When the respective counters match, the print data generation gate array 85 outputs the preset character image data as print image data to the print synthesis 1 circuit 83 or the print synthesis 2 circuit 84.
As a result, it is possible to actually perform composite output on the transfer paper 27.

Next, with reference to the flow charts shown in FIGS. 10 to 37 and the various screens of the liquid crystal touch panel 57 shown in FIGS. 1 and 38 to 45, the processing control of various modes in the present embodiment, etc. Will be described in order.

In this embodiment, the copy mode (image forming mode) is as follows: single-sided copy mode, single-sided original-single-sided copy mode, double-sided copy mode, single-sided original-double-sided copy mode, double-sided original-double-sided copy mode. Combined copy mode Every 2 sheets of original; 2-in-1 single-sided mode (one of page-order aggregated mode) Every 4 sheets of original; 4-in1 single-sided mode (one of page-order aggregated mode) 4-in-1 duplex mode (one of page-order aggregated mode) 4) 1-in-1 book mode (book type aggregation mode) etc. are prepared.

The ADF 11 shown in FIG. 2 has a pre-feed function (preliminary feeding function) for pre-feeding (preliminary feeding) the next document. That is, in a general ADF, when a document is continuously fed, even if the previous document is fed and conveyed on the contact glass 3, the next document remains stopped on the document table 12. However, in the ADF 11 having the pre-feed function, when the previous document is fed and conveyed on the contact glass 3, the next document is continuously moved from the document table 12 to the positions A and B in FIG. The sheet is fed and conveyed in the intermediate conveyance path indicated by, and is controlled so as to stop and stand by when it reaches the position B. According to such a pre-feed function, the transport time of the next document can be shortened by the distance between the positions A and B (route of the intermediate transport path), so the motor drive speed for the ADF 11 can be slowed down. It is possible to achieve low noise and low motor cost. On the other hand, this pre-feed function is premised on that the next original is always read by the CCD 10 and used for copying, and when a situation occurs in which the next original cannot be read by the CCD 10, in the intermediate conveyance path. Since there is no mechanism for automatically returning the pre-fed original to the original table 12, inconvenience may occur. The situation in which the next original cannot be read may be, for example, an interrupt copy, or the image memory 76 may become full and the original cannot be read, as will be described later. By the way,
In the illustrated example schematically shown in FIG. 2, the intermediate conveyance path indicated between the positions A and B does not seem to cause much trouble even if pre-feeding is performed, but in reality, the ADF 1
Due to the influence of the shape of the outer cover of No. 1 and the like, in the case of a small size original, most of the original has entered the intermediate conveyance path, and whether or not the original has already been read. There are many cases in which the decision is lost.

First, FIG. 10 shows a main flowchart. When the power is turned on, an initialization process is performed (step S1). The main contents of the initialization processing include resetting various flags, clearing various counters, clearing the image memory 76, resetting the image forming mode, and the like. After the initialization process, an event (a change factor of some kind) from the key input or the image forming engine is awaited (S2). When the operator performs any key operation, the operation unit 51 notifies the key input event. Similarly, some change in the image forming engine (for example, a change in the signal of the document set detection sensor 17 when a document is set on the ADF 11) is notified as an engine event. In any case, when a key input or engine event occurs, its type is determined (S3), if it is a key input event, the process shifts to key input event processing (S4), and if it is an engine event. Shift to engine event processing (S
5).

FIG. 11 shows the contents of the key input event process. In steps S11 to S17, a process of determining a key input is performed. Key input is print key 5
If it is 2 (Y in S11), copy processing is executed (S18). If the key input is the numeric keypad 53 (S1
2), numeric key processing is executed (S19). If the key input is the clear stop key 54 (Y in S13), clear / stop processing is executed (S20).
If the key input is a key related to print setting such as a page print key in the function keys 58 (Y of S14), print setting processing is executed (S21). The key input is the function key 58
If the key is a key related to double-sided setting (Y in S15), double-sided setting processing is executed (S22). If the key input is the key related to the aggregate setting in the function keys 58 (Y of S16), the aggregate setting process is executed (S23). If the key input is another key (Y in S17), another key process is executed (S24).

The contents of the print setting process are shown in FIG. This process is performed by using the basic screen shown in FIG. 4 or the format screen shown in FIG. 38 as the function keys 58, "page print key", "P1 and P2 keys", "1/5, 2 /

~ S36). When the "page print key" is pressed (Y of S31), the process of switching from the basic screen of FIG. 4 to the format setting screen shown in FIG. 38 is executed (S3).
7). When the "P1, P2 key", "1/5, 2/5 key" or "page allocation key" is pressed (S3
2 Y, S33 Y, or S36 Y), respectively, P1,
P2 key processing (S38), 1/5, 2/5 key processing (S
39) or page allocation key processing (S42) is executed. If the "release key" is pressed (S34
Y), the process of canceling the page print setting (S40) is executed, and then the process of switching the screen of the liquid crystal touch panel 57 to the basic screen as shown in FIG. 4 is executed (S41).
When the "setting key" is pressed (Y of S35), a process of switching the screen of the liquid crystal touch panel 57 to the basic screen as shown in FIG. 4 is performed (S41).

Here, the P1 and P2 key processing is executed as shown in FIG. First, P as the pagination mode
It is determined whether or not the normal page print mode of 1, P2 mode is set (S51), and if it is not set, the total page print mode of 1/5, 2/5 mode is canceled (S52), and then P1. , P2 mode is set (S53). If the P1 and P2 modes are set, the P1 and P2 modes are canceled (S54). That is. Press twice to cancel the mode.

The 1/5 and 2/5 key processing is executed as shown in FIG. First, 1 / as pagination mode
It is determined whether or not the total page print mode of 5, 2/5 mode is set (S61), and if not set, the normal page print mode of P1, P2 mode is canceled (S61).
After step 62), processing for setting the 1/5 and 2/5 modes (S63) is performed. Next, the screen of the liquid crystal touch panel 57 is switched to the total page number setting screen as shown in FIG. 39 (S64). On this screen, key input check is performed to confirm whether or not the number of originals does not match (S6).
5). If the unchecked key is pressed, the mismatch check mode is canceled (S66),
If the check key is pressed, the mismatch check mode is set (S67). On the other hand, if the 1/5, 2/5 mode is set in step S61, the 1/5, 2/5 mode is canceled (S6).
8). That is. Press twice to cancel the mode.

Further, the page allocation key processing when the "page allocation key" is pressed on the format setting screen shown in FIG. 38 is performed as shown in FIG. When the "page allocation key" is pressed, the screen of the liquid crystal touch panel 57 is switched to the page allocation screen as shown in FIG. 39, and the function keys 58 are "reverse side key""transfer sheet key""originalkey". A "release key" and a "setting key" appear.

The "reverse side key" is dedicated to the double-sided copy mode. When the "reverse side key" is pressed (S71), the reverse side mode is set (S72).
The reverse side mode is a mode in which page printing is combined and image-formed on the corner of the transfer paper on the side opposite to the closed portion.

The “transfer sheet key” and the “original key” are dedicated to the aggregate copy mode, and allow the user to arbitrarily select whether to perform pagination on a transfer paper basis or on an original image basis in the aggregate copy mode. Is a key for. When the "transfer sheet key" is pressed (S73), the transfer sheet mode is set to perform pagination in transfer sheet units in the aggregate copy mode (S74). When the "original key" is pressed (S75), the original mode in which page pagination is performed for each original image in the combined copy mode is set (S76). However, in the present embodiment, only the page-order aggregation copy mode allows the page-placing unit to be freely selected, and the 4-in-1 book mode is set to be automatically set to the original document mode.

When the "double-sided setting key" is pressed on the basic screen shown in FIG. 4, the screen is switched to the double-sided setting screen shown in FIG. 40, and the function keys 58 are "single-sided → double-sided key" and "double-sided → double-sided key". A "release key" and a "setting key" appear. Based on this screen, the double-sided setting process is performed as shown in FIG. First, in steps S81 to S84, it is determined which key is pressed. When the “single-sided → double-sided key” is pressed (Y of S81), the single-sided → double-sided key processing is performed (S85), and when the “double-sided → double-sided key” is pressed (Y of S82), Double-sided → double-sided key processing is performed (S86). If the "release key" is pressed (S8
3), after performing the process of releasing the double-sided setting (S87),
The screen is switched to the basic screen as shown in FIG. 4 (S88).
When the "setting key" is pressed (Y in S84), the screen is switched to the basic screen as shown in FIG. 4 (S88).

FIG. 17 shows the single-sided → double-sided key processing when the “single-sided → double-sided key” is pressed. First, it is determined whether the single-sided → double-sided mode is set (S9
1) If not set, the mode is the double-sided → double-sided mode or the aggregate mode, and these modes are canceled (S9).
2), single-sided → double-sided mode is set (S93). on the other hand,
In the determination in step S91, if the single-sided → double-sided mode is set, the single-sided → double-sided mode is canceled (S
94). That is, the mode is released by pressing the button twice.

FIG. 18 shows the double-sided → double-sided key processing when the “double-sided → double-sided key” is pressed. First, double-sided →
It is determined whether or not the duplex mode is set (S10
1) If it is not set, the mode is the single-sided → double-sided mode or the aggregation mode, so these modes are canceled (S10).
2), double-sided → double-sided mode is set (S103). On the other hand, in the determination of step S101, if the double-sided → double-sided mode is set, the double-sided → double-sided mode is canceled (S104). That is, the mode is released by pressing the button twice.

Next, when the "aggregate setting key" is pressed on the basic screen shown in FIG. 4, it is switched to the aggregate setting screen as shown in FIG. 42, and the function keys 58 are "2in1 single-sided key" and "4in1". Single-sided key "" 4in1 Double-sided key "" 4in1
Book key "cancel key""settingkey" appears. Based on this screen, the aggregation setting process is performed as shown in Fig. 19. First, in steps S111 to S116, which key is pressed is determined. "2 in 1 single sided key"
When any one of the "4in1 single-sided key", "4in1 double-sided key" and "4in1 book key" is pressed, the key processing (S117 to S120) corresponding to each key is executed.
When the "release key" is pressed (Y in S115),
After the processing of canceling the aggregation setting is performed (S121), the screen is switched to the basic screen as shown in FIG. 4 (S122). When the "setting key" is pressed (Y in S116), the screen is switched to the basic screen as shown in FIG. 4 (S122).

Here, the "2-in-1 single-sided key" is a key for designating a copy mode in which two original images are distributed on one side of the transfer paper in a left-right opened state, as shown in the screen of FIG. FIG. 20 shows the 2in1 single-sided key processing when the "2in1 single-sided key" is pressed. First, 2in1
It is determined whether the single-sided mode is set (S13
1) If it is not set, it is the double-sided mode or the aggregate mode, so these modes are canceled (S132), 2
The in1 single-sided mode is set (S133). On the other hand, if it is determined in step S131 that the 2in1 single-sided mode is set, the 2in1 single-sided mode is canceled (S13).
4). That is, the mode is released by pressing the button twice.

The "4 in 1 single-sided key" is for designating a copy mode in which four original images are distributed to one side of the transfer paper in a two-page order in a left-right opened state, as shown in the screen of FIG. This is a "4 in 1 single sided key"
FIG. 21 shows the 4-in-1 single-sided key processing when is pressed. First, it is determined whether or not the 4in1 single-sided mode is set (S141). If not set, the mode is canceled because the mode is the double-sided mode or the aggregate mode (S142), and the 4in1 single-sided mode is set (S14).
3). On the other hand, in the determination of step S141, 4in1
If the single-sided mode is set, the 4-in-1 single-sided mode is canceled (S144). That is, the mode is released by pressing the button twice.

Further, the "4 in 1 double-sided key" is a key for designating a copy mode in which four original images are distributed in page order in the left-right opened state on both sides of the transfer paper, as shown in the screen of FIG. FIG. 22 shows the 4-in-1 double-sided key processing when this "4-in-1 double-sided key" is pressed. First, it is determined whether or not the 4in1 double-sided mode is set (S151), and if not set, these modes are canceled because the single-sided mode or the aggregate mode is set (S15).
2) Set the 4-in-1 double-sided mode (S153). On the other hand, if it is determined in step S151 that the 4-in-1 duplex mode has been set, the 4-in-1 duplex mode is canceled (S154). That is, the mode is released by pressing the button twice.

Further, as shown in the screen of FIG. 42, the "4 in 1 book key" is 1 when folded in the middle and closed.
This is a key to specify the copy mode in which four original images are distributed on both sides of the transfer paper so that pages 4 to 4 are in the page order. When this "4in1 book key" is pressed, it is a 4in1 book. The key processing is shown in FIG. First, it is determined whether or not the 4in1 book mode is set (S161). If it is not set, the mode is canceled because it is the single-sided mode or the aggregation mode (S162) and the 4in1 book mode is set (S16).
3). On the other hand, in the determination of step S161, 4in1
If the book mode has been set, the 4in1 book mode is canceled (S164). That is, the mode is released by pressing the button twice.

Next, the key processing of the ten keys 53 and the clear stop key 54 will be described. First, the numeric keypad 53
24 will be described with reference to FIG. In the ten-key processing, the meaning of the key input differs depending on which screen the ten-key 53 is pressed. First, when the ten key 53 is pressed on the total page setting screen as shown in FIG. 38 (S171), the total number of pages to be printed is set (S172). When the ten key 53 is pressed on the total document number setting screen as shown in FIG. 44 when the image memory 76 is out of memory (S17).
3) The total number of originals is set (S174). further,
When the ten key 53 is pressed in the remaining original number setting screen as shown in FIG. 45 when the image memory 76 is out of memory (S175), the remaining original number is set (S17).
6). For other screens, the number of copies is set in accordance with the operation of the ten keys 53 (S177).

Next, the key processing of the clear stop key 54 will be described with reference to FIG. In the clear stop key processing, the meaning of the key input differs depending on which screen the clear stop key 54 is pressed. First,
When the clear stop key 54 is pressed on the total page setting screen as shown in FIG. 38 (S181), the total number of pages is cleared (S182). In addition, the image memory 7
When the clear stop key 54 is pressed in the total document number setting screen as shown in FIG. 42 when the memory is over in 6 (S183), the total number of documents is cleared (S18).
4). Further, when the clear stop key 54 is pressed on the remaining original number setting screen as shown in FIG. 43 when the image memory 76 is out of memory (S185), the remaining original number is cleared (S186). Further, if the copy operation is in progress (Y in S187), the copy is interrupted (S18).
8) If the copy operation is not in progress (N of S187), the number of copies is cleared (S189).

Further, the control of the actual copy operation will be described with reference to FIG. This copy operation is executed by pressing the print key 52, but since the process differs depending on which copy mode is set, it is determined in step S191 or S193 which copy mode is set. To be done. When the duplex mode is set (Y in S191), the duplex copy operation is executed (S192). If the aggregation mode is set (Y in S193), the aggregation copy operation is executed (S194). If it is neither the duplex mode nor the aggregation mode (N of S193), the one-sided copy operation is executed (S195).

The copy operation for each mode will be described below. First, the one-sided copy operation will be described with reference to the flowcharts of FIGS. 27 and 28. In this process, after the start of copying, it is determined every time whether or not the image memory 76 has a memory capacity necessary for reading one page of the original image (S201). This determination processing is executed by the remaining amount detecting means. When the memory capacity for one surface or more remains (Y in S201), the ADF 11 pre-feeds the document (S202). That is, the original on the original table 12 is fed to the position B. Next, the operation of feeding the original onto the contact glass 3 and the operation of counting the number of originals (the number of original pages) are performed (S203a). The counting operation of the number of documents in this case is executed by the counting means. At this point, it is sequentially checked whether or not there is a next original and whether or not the image memory 76 has a remaining capacity of two or more surfaces (S20).
3b, S203c). The determination process of step S203c is also executed by the remaining amount detecting means. In this determination process, if there is the next original and the remaining capacity of the image memory 76 is two or more, the next original on the original table 12 is pre-fed to the position B (S203d). Therefore, at this time point, the original document exists on the contact glass 3 and the next document exists on the intermediate conveyance path. Therefore, the document existing on the contact glass 3 is read by the CCD 10 and the image information is stored in the image memory 76 (S203e). If there is no next original document or there is no remaining capacity for two or more pages, the document reading operation is started without pre-feeding. After that, if the pre-fed original is present (Y in S203f), steps S203a to S203e are performed.
The processing operation of is repeated.

When the pre-fed originals are exhausted, it is judged whether or not the originals remain on the original table 12 (S204), and as long as the originals remain, the step S20 is performed.
The processes of 1 and below are similarly repeated.

When the original image is read, it is checked whether the total page print mode is set (S205), and if the total page print mode is set, it is checked whether the total number of pages is input (S206). When the total number of pages is input, the input total number of pages and the count value of the number of originals are compared (S207). As a result of this comparison, if they do not match (N of S207), the screen is switched to the screen for displaying the number of documents confirmation as shown in FIG. 44 (S).
208).

After that, it is checked whether or not there is a re-read (S209), and if there is a re-read, the read operation is repeated again.
If there is no re-reading, the process proceeds to step S213 and later described later.

Now, let us consider a case where the image memory 76 is out of memory while the document is being read. If it is determined in step S201 that the image memory 76 does not have one surface as the remaining capacity and there is no remaining capacity, the processing of step S202 and subsequent steps is not performed (the reading operation is interrupted), and pagination is performed. It is checked whether or not the print mode with is set (S210). When the print mode, particularly the total page number print mode, is set, the screen is switched to a screen displaying that the memory is over and the total page number should be input as shown in FIG. 1 (S21).
1). This screen display shows "The memory is full.
The total number of pages cannot be automatically counted. Please specify the total number of pages. To cancel the page printing, press the [Cancel and Close] key. And a message prompting the user to perform an input operation, and an input screen state for actually inputting the total number of pages of the document is entered. The processing of step S211 is executed by the notification input means. As a result, the user can deal with the problem by counting the number of manuscripts himself and input the total number of pages on this screen. That is, the device recognizes the input number as the total number of pages instead of the counting result by the counting means. If it is not the print mode, the memory is simply displayed (S21).
2).

As the screen display in step S211, as shown in FIG. 43, instead of the display prompting the input of the total number of pages, the display prompting the input of the remaining number of original pages that have not been read yet. May be replaced with That is,
Instead of displaying "Please specify the total number of pages.", For example, "Please input the number of remaining originals." And its input screen are displayed. As a result, the user can deal with the problem by counting the number of remaining documents by himself and inputting the number as the number of remaining documents on this screen. That is, the apparatus recognizes the total number of pages by adding the number of originals counted by the counting means up to that point and the number of remaining originals input on the screen.
In particular, it is easier for the user to count the number of remaining documents than to count the total number of pages.

On the ADF 11 side, if there is a next document (Y in S203b), it is checked at that time whether or not the image memory 76 has a memory capacity for two sides in consideration of reading the next document. However, (S203c), if there is no memory capacity for two sides (N of S203c), the pre-feed is not performed for the next original. The preliminary feed control means executes the processing control that does not perform this pre-feed. In this case, since the memory capacity is insufficient in the subsequent processing, the process moves to step S211. For example, as shown in FIG. Since the original is not pre-fed into the intermediate conveyance path and the reading operation is suspended, it becomes clear that the original remaining on the original table 12 is an unread original, and the remaining number of originals can be grasped. Will be certain. Further, if it has been pre-fed, the pre-fed original must be taken out from the intermediate conveyance path, but there is no such trouble.

When all the originals have been read, it is checked whether the print mode is set (S213). If the print mode is set, it is checked whether the total page print mode is set (S214). In the total page print mode, the current page and the total page are printed in the fractional format using "/" (S215). If it is not the total page print mode, since it is the normal page print mode, only the current page is printed (S216). After that, the single-sided copy operation for the original image is executed regardless of whether page printing is performed (S217). As a result, the page information is displayed as shown in
As shown in, the composite print is made in the upper right corner.

The processes of steps S213 to S217 are repeated for the set number of sheets (S218), the current page is counted up (S219), and the same one-sided copy operation is repeated for the succeeding document (S22).
0).

Next, the double-sided copy operation will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. In this processing, after the start of copying, it is determined every time whether or not there is a memory capacity required for reading the two original document images (for the front surface and the back surface) in the image memory 76 (S).
221). This determination processing is executed by the remaining amount detecting means. If the memory capacity of 2 or more is left, (S
(Y of 221), the document is pre-fed in the ADF 11 (S222). That is, the original on the original table 12 is fed to the position B. Next, the operation of feeding the original onto the contact glass 3 and the operation of counting the number of originals (the number of original pages) are performed (S223a). The counting operation of the number of documents in this case is executed by the counting means. At this point, it is sequentially checked whether or not there is a next original document, and whether or not the image memory 76 has a remaining capacity of four surfaces (for two front and back surfaces) or more (S223b, S223b, S223c). Step S223
The determination process of c is also executed by the remaining amount detecting means. In this determination processing, there is the next original and the image memory 7
When the remaining capacity of 6 is four or more, the next document on the document table 12 is pre-fed to the position B (S223).
d). Therefore, at this time point, the original document exists on the contact glass 3 and the next document exists on the intermediate conveyance path. Therefore, the original existing on the contact glass 3 is read by the CCD 10,
The image information is stored in the image memory 76 (S223
e). When there is no next original or when there is no remaining capacity of four or more pages, the original reading operation is started without pre-feeding. After this, if the pre-fed original is present (Y in S223f), step S223.
The processing operations from a to S223e are repeated.

When the pre-fed originals are exhausted, it is determined whether or not the originals remain on the original table 12 (S224). As long as the originals remain, the step S22 is performed.
The processes of 1 and below are similarly repeated.

When the original image is read, it is checked whether the total page print mode is set (S225), and if the total page print mode is set, it is checked whether the total page number is input (S226). If the total number of pages has been input, it is checked whether the duplex mode is the duplex-duplex copy mode (S227). The size is compared with the count value (S228), and if it is not the double-sided copy mode (if it is the single-sided / double-sided copy mode), the size of the input total number of pages and half of the count value of the number of originals is compared (S228). S229). As a result of the comparison in step S228 or S229, if they do not match,
The screen is switched to the screen for displaying the document number confirmation display as shown in 4 (S230).

Then, it is checked whether or not there is a reread (S231), and if there is a reread, the read operation is repeated.
If there is no re-reading, the process proceeds to step S235 and later described later.

Now, let us consider a case where the image memory 76 is out of memory while the document is being read. When it is determined in step S221 that the remaining capacity of the image memory 76 is not equal to two and there is no remaining amount, the processing of step S222 and subsequent steps is not performed (the reading operation is interrupted) and pagination is performed. It is checked whether or not the print mode with is set (S232). If the print mode, especially the total page number print mode, is set, the screen is switched to a screen displaying that the memory is over and the total page number should be input as shown in FIG. 1 (S23).
3). As described above, this screen display is accompanied by the reading interruption reason and the message prompting the input operation, and is in an input screen state for actually inputting the total number of pages of the manuscript. The process of step S231 is executed by the notification input means. As a result, the user can deal with the problem by counting the number of manuscripts himself and input the total number of pages on this screen. That is, the device recognizes the input number as the total number of pages instead of the counting result by the counting means. If it is not the print mode, the memory over is simply displayed (S234).

Even in the screen display in step S233, as in the case described above, as shown in FIG. 43, instead of the display prompting the input of the total number of pages, the number of remaining original pages that have not yet been read is displayed. It may be replaced with the display prompting the input of.

On the ADF 11 side, when there is a next original (Y in S223b), it is checked at that time whether or not the image memory 76 has a memory capacity for four sides in consideration of reading the next original. However, (S223c), if there is no memory capacity for four sides (N of S223c), pre-feed is not performed for the next document. The preliminary feed control means executes the processing control that does not perform this pre-feed. In this case, since the memory capacity is insufficient in the subsequent processing, the process proceeds to step S232. For example, in the case of the mode of inputting the remaining number of originals as shown in FIG. Since the reading operation is suspended without being pre-fed into the intermediate conveyance path, it becomes clear that the original document remaining on the document table 12 is an original document that has not been read, and the remaining number of original documents remains. The grip is secure. Further, if it has been pre-fed, the pre-fed original must be taken out from the intermediate conveyance path, but there is no such trouble.

When all the originals have been read, it is checked whether the print mode is set (S235). If the print mode is set, it is checked whether the total page print mode is set (S236). In the total page print mode, the current page and the total page are printed in a fractional format using "/" (S237). If it is not the total page print mode, since it is the normal page print mode, only the current page is printed (S238). Thereafter, the front side or back side copying operation relating to the original image is executed regardless of whether page printing is performed or not.

Here, it is checked whether or not it is a back side copy (S239). If it is not a back side copy (front side copy), the copy operation is executed as it is (S240). On the other hand, at the time of back side copying, it is checked whether the reverse side mode is set for page printing (S241). If the reverse side mode is set, the print position of the page information is changed to the upper left. After the processing is performed (S242), the back side copy operation is performed (S240). As a result, the pagination when the reverse side mode is set is corrected so as to be the same position on the front and back sides apart from the closed portion of the transfer paper 27.

The steps S235 to S242 are repeated for the set number of sheets (S243), the current page is counted up (S244), and the same copying operation is repeated for the succeeding document (S248).
However, after the count-up in step S244, it is checked whether it is a front side copy or a back side copy (S245), and if it is a front side, it is switched to a back side (S).
246), if it is the back side, switch to the front side (S2
47).

Further, the aggregate copy operation will be described with reference to the flow charts shown in FIGS. In this process, after the start of copying, it is determined every time whether or not the image memory 76 has a memory capacity required for reading one page of the original image (S251). This determination processing is executed by the remaining amount detecting means. If the memory capacity for one surface or more remains (Y in S251), ADF1
In step 1, the document is pre-fed (S252). That is, the original on the original table 12 is fed to the position B. next,
The operation of feeding the original onto the contact glass 3 and the operation of counting the number of originals (the number of original pages) are performed (S253a).
The counting operation of the number of documents in this case is executed by the counting means. At this point, it is sequentially checked whether or not there is a next original and whether or not the image memory 76 has a remaining capacity of two or more surfaces (S253b, S253c). Step S253c
The determination process of is also executed by the remaining amount detecting means. In this determination processing, there is the next original and the image memory 76
If the remaining capacity of 2 is two or more, the next document on the document table 12 is pre-fed to the position B (S253d).
Therefore, at this time point, the original document exists on the contact glass 3 and the next document exists on the intermediate conveyance path. Therefore, the document existing on the contact glass 3 is read by the CCD 10 and the image information is stored in the image memory 76 (S253e). If there is no next original document or there is no remaining capacity for two or more pages, the document reading operation is started without pre-feeding. After that, if the pre-fed original is present (Y in S253f), steps S253a to S2 are performed.
The processing operation of 53e is repeated.

When the pre-fed originals are exhausted, it is determined whether or not the originals remain on the original table 12 (S254), and as long as the originals remain, step S25 is performed.
The processes of 1 and below are similarly repeated.

Now, let us consider a case where the image memory 76 is out of memory while the original is being read. When it is determined in step S251 that the image memory 76 does not have one surface as the remaining capacity and there is no remaining amount, the processing in step S252 and subsequent steps is not performed (the reading operation is interrupted), and pagination is performed. It is checked whether or not the print mode with is set (S255). When the print mode, particularly the total page number print mode, is set, the screen is switched to a screen displaying that the memory is over and the total page number should be input as shown in FIG. 1 (S25).
6). As described above, this screen display is accompanied by the reading interruption reason and the message prompting the input operation, and is in an input screen state for actually inputting the total number of pages of the manuscript. The processing of step S256 is executed by the notification input means. As a result, the user can deal with the problem by counting the number of manuscripts himself and input the total number of pages on this screen. That is, the device recognizes the input number as the total number of pages instead of the counting result by the counting means. If it is not the print mode, the memory over is simply displayed (S257).

Even in the screen display in step S256, as shown in FIG. 43, as in the case described above,
Instead of the display prompting for the input of the total number of pages, the display prompting for the input of the number of remaining original pages that have not been read may be replaced.

On the ADF 11 side, if there is a next document (Y in S253b), it is checked at that time whether or not the image memory 76 has a memory capacity of two sides in consideration of reading the next document. However, if the memory capacity for two sides is not available (S253c) (N in S253c), the pre-feed is not performed for the next document. The preliminary feed control means executes the processing control that does not perform this pre-feed. In this case, since the memory capacity is insufficient in the subsequent processing, the process proceeds to step S232. For example, in the case of the mode of inputting the remaining number of originals as shown in FIG. Since the reading operation is suspended without being pre-fed into the intermediate conveyance path, it becomes clear that the original document remaining on the document table 12 is an original document that has not been read, and the remaining number of original documents remains. The grip is secure. Further, if it has been pre-fed, the pre-fed original must be taken out from the intermediate conveyance path, but there is no such trouble.

When the reading of the original is completed, it is checked whether the total page print mode is set (S258), and if the total page print mode is set, it is checked whether the total number of pages is input (S259). If the total number of pages has been entered, the type of aggregation mode is checked (S26).
0). 2in1 if the aggregation type is 2in1 single-sided mode
One-sided total page determination processing is performed (S261), 4in1 one-sided total page determination processing is performed (S262), 4in1 both-sided total page determination processing is performed (S263), and 4in1 single-sided total page determination processing is performed (S263). If it is the 4 in 1 book mode, the total page determination process of the 4 in 1 book is performed (S264).

The 2-in-1 single-sided total page determination process is shown in the flowchart of FIG. First, it is checked whether the original page printing mode is selected (S281), and if the original page printing mode is selected, it is checked whether the input total number of pages is equal to the count value of the original number counter (S282). . In the page-by-transfer sheet printing mode, it is checked whether the total number of input pages is equal to half the count value of the original number counter (S283).

The 4-in-1 single-sided total page determination process is shown in the flowchart of FIG. First, it is checked whether the original page printing mode is selected (S286). If the original page printing mode is selected, it is checked whether the input total number of pages is equal to the count value of the original number counter (S2).
87). In the page-to-transfer printing mode, it is checked whether the total number of input pages is equal to 1/4 of the count value of the original number counter (S288).

The total page determination processing for both 4 in 1 sides is shown in the flowchart of FIG. First, it is checked whether the original page printing mode is selected (S291). If the original page printing mode is selected, it is checked whether the total number of pages input is equal to the count value of the original number counter (S2).
92). In the page-by-transfer page printing mode, it is checked whether the total number of input pages is equal to 1/4 of the count value of the original number counter (S293).

FIG. 37 shows the total page determination process for a 4 in 1 book.
Is shown in the flowchart of FIG. In this case, since pagination is automatically performed for each document image unit set, the total number of pages input is ¼ of the count value of the document number counter.
Is checked (S296).

In the judgment processing of these steps S261 to S264, if they do not match, the screen is switched to a screen for displaying the total page number confirmation display as shown in FIG. 45 (S26).
5). After that, it is checked whether or not there is re-reading (S266), and if there is, the reading operation is repeated.

When all the originals have been read, it is checked whether the print mode is set (S267). If the print mode is set, it is checked whether the total page print mode is set (S268). In the total page print mode, the current page and the total page are printed in the fractional format using "/" (S269). If it is not the total page print mode, since it is the normal page print mode, only the current page is printed (S270). At this time, it is checked whether or not the page-by-document page print mode is set as the pagination mode (S271). If the page-by-document page print mode is set, the current page is counted up (S272). The processing of the document images to be combined on the same transfer paper is advanced (S273). This ensures pagination in document image units for document images distributed and combined on the same transfer paper. If it is not the page printing mode for each original, the page count-up process (S27)
Without carrying out step 2), the processing of the document images corresponding to the sheets to be combined on the same transfer sheet is advanced (S273). In this way, when the original images to be collected are aligned on the same surface of the transfer paper 27, the copy operation is performed (S274).

The processes of steps S267 to S274 are repeated for the set number of sheets (S275). If the page-by-page printing mode is not set (if the page-by-page printing mode is selected) (N in S276), the current The page is counted up (S277), and the same copy operation is repeated for the subsequent document (S278). In the page-by-document page print mode (Y in S276), the same copy operation is repeated for the subsequent document without counting up the current page at this point (S278).

According to the first aspect of the invention, in addition to the reading means for reading the original image, the storage means for storing the image information read by the reading means, and the image information of the original on the transfer paper. Additional printing means for synthesizing and printing page information, counting means for counting the number of original pages before and after the reading operation by the reading means, remaining amount detecting means for detecting the remaining amount in the storage means, and the additional By the mode specifying means for specifying the total page printing mode for printing in the fractional form with the total number of pages as the denominator as the printing mode of the page information by the printing means, and the reading means when the total page printing mode is specified by the mode specifying means. If the remaining amount detecting means detects that there is no remaining amount in the storage means at the time of reading the original image, the reading operation by the reading means is interrupted. And a notification input unit for urging the user to input the total number of pages accompanied by an input screen for inputting the total number of pages of the document. Therefore, the number of original pages is counted in the total page number print mode. Even if the storage means runs out while the original image is being read, the reading interruption means interrupts the reading operation and the notification input means prompts the user to input the total number of pages. Since the number of pages can be input as it is,
The user may input the total number of pages by counting the number of pages of the manuscript, and the image information stored in the storage unit by acquiring the total number of pages even if the counting by the counting unit is interrupted midway. With respect to, it is possible to perform pagination printing accompanied by the total number of pages. Therefore, even if the storage means with a finite capacity becomes full on the way, the user does not need to cancel the function of the total page number print mode on the way It can be executed in combination.

According to the invention described in claim 2, instead of the notification input means in the invention described in claim 1, the reading means is accompanied by an input screen for inputting the number of the remaining manuscript pages. The notification input means for urging that the remaining number of manuscript pages should be input is provided.
It is possible to obtain the same effect as in the case of the described invention,
In particular, since the notification input means prompts the user to input the number of remaining original pages that have not been read by the reading means and inputs the number of original pages, the number of original pages to be counted by the user is reduced as much as possible and the burden on the user is reduced. Can also be lighter.

According to the third aspect of the invention, in the invention of the second aspect, the reading means is provided with an intermediate conveying path for conveying the original in the vicinity of the image reading position, and a function of preliminarily feeding the next original. If the remaining amount detecting means detects that the storage means has no remaining amount when the original image is read by the reading means when the total page print mode is designated by the mode designating means, Since the automatic document feeder has a preliminary feeding control means for stopping the preliminary feeding of the next original, the storage means becomes full at the time of reading the previous original and the user counts and inputs the number of remaining original pages. When scanning, the preliminary feeding is stopped and there are no documents that have been preliminarily fed to the intermediate conveyance path.Therefore, the presence of the documents is still read and the counting errors are reduced, and the correct total number of pages is reduced. It is possible to carry out the page with printed on.
