Abstract

PURPOSE: To conduct one-side print forcibly when pages of different sizes are in mixture and print is started while part of received documents is stored. CONSTITUTION: Either a double side print section 200 or a one-side print section 300 is selected by a command from a print form command section 100. On the other hand, when unarrangement of pages of documents stored in a file 12 is detected regardless of the command, a page size discrimination section 400 outputs a signal (a) to allow a changeover section 500 to select the one side print section 300. When a print request of a document having been already received comes during reception, a signal (b) is outputted similarly to allow the changeover section 500 to select the one side print section 300.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine capable of printing a received document on both sides of recording paper.

[0002]

2. Description of the Related Art A copying apparatus is known which prints image information read from both sides of a document on both sides of a recording sheet. In particular, in recent years, a multifunctional device in which a facsimile communication function is added to the copying device has begun to be put into practical use.

By the way, as described above, not only image information read from both sides of the same document but also image information read from documents of different sizes may be printed on both sides of the recording paper. Therefore, in the case of such mixed sizes, the recording paper is automatically selected based on the first page original, and the second page image information is enlarged or reduced according to the size of the first page original. , A double-sided copying machine configured to always print on both sides of recording paper has been proposed (Japanese Patent Publication No.
-10069).

Further, when printing on the back side of the recording paper, when it is detected that the original size instructed by the original size instructing means is different from the original size at the time of front side printing, the back side printing is not carried out and a new recording paper is pulled out. There has been proposed a double-sided copying machine adapted to print on the same (JP-A-61-261751).

[0005]

When a facsimile function is added to the above-mentioned double-sided copying machine to print a received document on both sides in the same manner as in copying, there are the following problems. First, using the function of the former copier,
When printing with the page size enlarged or reduced, the sender may not be aware of double-sided printing.
In particular, the image information may be reduced so that the content of the document becomes unreadable. As described above, due to the essential difference between a copying machine in which the operator can check the contents of the original while printing on both sides and a facsimile machine in which the receiving operator cannot know the contents of the original in advance, the copying machine has been adopted. There is a problem that the existing function cannot be used as it is for printing a received document.

On the other hand, in the case of the latter copying machine, for example, an original using A4 size paper vertically (A4 portrait original) and an original using A4 size paper horizontally (A4 landscape original)
Even if the original size is the same, it is determined that they are different sizes, and double-sided printing is prohibited. Therefore, the same A
Despite being a four-size original, recording sheets printed on both sides and recording sheets printed on one side are mixed, and there is a problem in that uniformity in document organization is lacking. In addition, when double-sided printing and single-sided printing are mixed, there is a problem in the apparatus configuration that the control of recording paper conveyance and the control of page layout become complicated.

In order to solve the above problems, in a copying machine, when A4 portrait originals and A4 landscape originals are mixed, the operator can preliminarily align the orientations of the originals. There is a case in which the document created in 1. is transmitted as it is using the FAX modem. In such a case, even if A4 portrait originals and A4 landscape originals are mixed, there is no way to correct it.

Further, in the facsimile communication, when the memory for storing the received document becomes full (memory full) during reception, the received document is printed out to secure the memory area. When this print is executed with the double-sided printing method, the size of the page received after that is not fixed, and as a result, the double-sided printing page and the single-sided printing page are mixed, resulting in the same problem as above. Occurs.

As described above, since the conventional double-sided printing function has many inconveniences when it is used as it is in the facsimile apparatus, the above problems are solved not only in the multifunction copying apparatus having the facsimile function but also in the facsimile apparatus alone. Realization of double-sided printing function is required.

The present invention has been made to solve the above problems, and an object thereof is to provide a facsimile apparatus having a print function in consideration of the case where different sizes of pages of a facsimile received document are mixed. Especially.

[0011]

SUMMARY OF THE INVENTION In order to solve the above problems and achieve the object of the present invention, the storage means for storing a received document and the size of all pages of the document stored in the storage means are unified. Firstly, a page size determination means for determining whether or not pages of different sizes are mixed and a prohibition means for prohibiting double-sided printing when it is determined that different sizes are mixed are provided. There is a feature of.

Further, according to the present invention, the page size determining means is configured to consider that the sizes of all pages are unified when all the pages have the same size by the rotation processing, and the size of all the pages. The second point is that an image rotating means for unifying the orientation of the document and transferring the same to the printer unit is further provided when the documents are considered to be unified.
There is a feature of.

Further, according to the present invention, storage means for storing the received document, reception state determination means for determining whether or not the received document is being received, and print request for the document stored in the storage means are made. At this time, when it is determined by the reception state determination means that the rest of the document is being received,
Thirdly, it has a prohibition means to prohibit double-sided printing.
There is a feature of.

[0014]

According to the first feature, it is possible to determine whether or not all the pages of the received document stored in the storage unit have the same size, and the result of this determination indicates that pages of different sizes are mixed. When the determination is made, the one-sided printing is forcibly executed.

Further, according to the second feature, even if there are pages with different orientations, if they have the same size by rotation, it is considered that all pages have the same size, and The image rotating means aligns the orientations of all pages.

According to the third feature, when a print instruction is issued, it is detected whether or not the continuation of the document for which the print instruction is made is being received. Single-sided printing is executed.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 2 is a schematic diagram showing the configuration of the facsimile apparatus according to the embodiment of the present invention. In the figure, a reading device (scanner) 1 for a transmission original is provided in the upper part of the apparatus, and a recording paper tray 2 for storing recording paper is provided in the lower part. The recording paper trays are usually provided in multiple stages so that a plurality of different sizes can be prepared. In the illustrated example, a three-stage tray is adopted. On the other hand, an electrophotographic image forming / transferring device 3 for printing the image information of the original read by the scanner 1 on a recording sheet is arranged in the center of the facsimile apparatus. Further, two types of output trays for printed recording paper are provided above it. One is a face-up tray 4 for discharging with the surface of the recording paper facing up, and the other is a face-down tray 5 for discharging with the surface of the recording paper facing down. Further, there is provided a paper transporting device 6 for pulling out the recording paper from the recording paper tray 2, transporting it to the image forming / transferring device 3, and discharging the printed recording paper to the face-up tray 4 or the face-down tray 5. . The detailed structure of the sheet conveying device 6 will be described later with reference to FIG.

Next, the hardware structure of the control device in the facsimile machine will be described. In FIG. 3, the control panel 7 is composed of an operation section including switches and a keyboard for operating the facsimile apparatus, and a display section such as a liquid crystal panel for displaying an operation state and the like. The scanner 1 is a device for reading an original, reads the original in synchronization with a line synchronization signal at a constant interval, and writes the read original in the page memory 8 as one page corresponding to the interval of the page synchronization signal. Be done. Page memory 8
Is, for example, A4 size, 400 dots / inch (dp
It is composed of a DRAM that can store the image of i). The image image stored in the page memory 8 is rotated at the beginning of page processing by the image rotation unit 9 according to a predetermined command, and output to the printer unit 10. The encoding / decoding unit 11 converts the image image sent from the page memory 8 into M
File 1 encoded by a known compression method such as H or MR
The data sent from the file 12 is expanded and converted into an image image while being transferred to the image memory 8
It has the function to transfer to. The file 12 is composed of a large capacity memory such as a DRAM or a hard disk, and stores the compressed image image. Reading and writing of data with respect to the file 12 is performed via a file interface (I / F) 13. Data transfer between the encoding / decoding unit 11, the page memory 8 and the image rotation unit 9 is performed by the codec interface (I / F) 14.
Controlled by.

The line control unit 15 performs the communication procedure of CCITT G3 or G4, and performs a process of dividing the image data of a plurality of pages sent from the transmitter into page units and storing them in the file 12. The RAM 16 is composed of DRAM and stores variables necessary for control. The CPU 17 controls the entire facsimile apparatus according to a predetermined program, and also executes a facsimile transmission control procedure. It should be noted that each of the above-mentioned components exchanges data with each other via the system bus 18.

Next, the operation of this embodiment by the facsimile apparatus having the above-mentioned structure will be described with reference to the functional block diagram of the main part of the facsimile apparatus. In FIG. 1, a print form instruction unit 100 has a function of inputting a double-sided print instruction, and is set on the control panel 7. The double-sided printing unit 200 executes the double-sided printing process according to the predetermined procedure according to the double-sided printing instruction. on the other hand,
The single-sided printing unit 300 executes the single-sided printing process according to a predetermined procedure when the double-sided printing instruction is not issued. Normally, printing is executed according to the instruction from the print form instruction unit 100, but in the following cases, the one-sided print unit 300 is forcibly activated. First, the size of all pages of the file to be printed is not uniform and pages of different sizes are mixed. Second
This is the case when a print request is made to a document which has already been received while the document is being received.

That is, the page size determination unit 400 detects the document size of each page of the received document stored in the file 12 and determines whether different sizes are mixed in the document to be printed. When different sizes are mixed, the detection signal a is output to the switching unit 500. The switching unit 500 is normally switched to the double-sided printing unit 200 side, but is switched to the single-sided printing unit 300 side by the detection signal a.

Further, the reception state judging section 600 judges whether or not the reception is in progress. The reception state determination unit 600, when there is a print request and a double-sided print instruction is input,
If the signal is being received, the detection signal b is supplied to the switching unit 500.
The switching unit 500 is switched to the single-sided printing unit 300 side in response to the detection signal b. As a result of the switching of the switching unit 500, the single-sided printing unit 300 is selected regardless of the instruction from the print form instructing unit 100.

Further, in this embodiment, a management table 700 for managing the size of each page of the document is provided. Although details of the management table 700 will be described later, the page size determination unit 400 determines the size even if the vertical and horizontal orientations such as A4 portrait and A4 landscape differ depending on the page size attributes managed by the management table 700. Are treated as the same size. However, the data of the page whose vertical and horizontal orientations are different from the planned orientation is input to the double-sided printing unit 200 after being rotated by the image rotation unit 9.

Next, the operation of the facsimile apparatus having the above configuration will be described with reference to the flowchart. First, FIG. 4 shows the entire operation. In the figure, in step S1, the file interface 13 is requested to perform a process for reading the received document from the file 12. This request is R
This is done by issuing a DOPEN command. In step S2, it is determined whether or not there is a double-sided print instruction. This judgment is input from the control panel 7 in advance and is stored in the RAM.
The setting value stored in 16 is used. If there is a double-sided print instruction, the process proceeds to step S3, and it is determined whether or not the reception of the currently opened received document is completed.
This judgment is made based on the setting of the variable RXFLAG stored in the RAM 16. The normal print job is a task that is started after the reception is completed, but the file 12
If is determined to be full, the print job is started before the reception is completed.

If the reception is completed, the flow advances to step S4 to execute a page size determination process. The variable PSAME is determined by this determination processing, and details of this processing will be described later with reference to FIG. In step S5, it is determined whether the sizes of all pages are the same, depending on whether the value of the variable PSAME determined by the page size determination process is "1". That is, if the variable PSAME is "1", it is determined that the sizes of all pages are the same.
If all pages are the same, the process proceeds to step S6 to perform the output tray setting process, and the process proceeds to step S7 to execute the double-sided printing process. The output tray setting processing will be described later with reference to FIG. 7, and the details of the double-sided printing processing will be described later with reference to FIG. In step S8, the file interface 13 is requested to perform processing for ending the reading from the file 12. This request is made by issuing the RDCLOSE command. In step S9, the memory block reserved for managing the received document file on the file 12 is released, and the processing of the print job is completed. The memory block is released by issuing the DPURGE command.

If it is determined in step S2 that there is no double-sided printing instruction, the process proceeds to step S10 to perform output tray setting processing, and in step S11, single-sided printing processing is executed. Details of the single-sided printing process will be described later with reference to FIG. If it is determined in step S3 that the reception is not completed, the process proceeds to step S12, and the paper transport device 6 is set so that the recording paper is output to the face-down tray 5.

Next, details of the page size determination process will be described. First, the page size management table will be described with reference to FIG. In the figure, a counter value is set for each size of recording paper shown in the major classification, and further,
The large classification is divided into small classifications depending on whether the recording paper is vertical size or horizontal size, and a counter value is set for each small classification. The counter value of this management table is updated by the determination result of the size of each received document stored in the file 12 for each page.

FIG. 5 is a flow chart showing a page size determination process for updating the counter value. In the figure, in step S20, each counter value of the page size management table is initialized to "0". In step S21, a variable CN indicating the current number of processed pages is initialized by setting "1" to prepare for opening the first page. In step S22, it is determined whether the variable CN exceeds the variable PN indicating all pages of the received document. If this determination is negative, the process proceeds to step S23, where the ROPEN command is issued and the page indicated by the variable CN (hereinafter referred to as "CN
"Page") is opened to obtain the size attribute of the page. Note that this size attribute can be determined by the width and resolution of image data detected by the line control unit 15 by the protocol at the time of reception, the number of lines obtained by the EOL counter value of the compressed image, and the like. It is a standard size such as horizontal. In step S24,
Issue the RPCROSE command to close the CN page.

In step S25, the counter value of the small classification in the management table is incremented (+1). In step S26, the major classification counter value in the management table is incremented (+1). In step S27,
It is determined whether the variable CN is the same as the counter value of the major classification. If this judgment is affirmative, the routine proceeds to step S28, where the value of the variable CN is incremented (+1).

If the determination in step S27 is negative, the flow advances to step S29 to set "0" to a variable PSAME indicating that all pages have the same size. In other words, if the size is the same and only the directions are different vertically and horizontally, the counter values of the large classification and the current number of processed pages should match, and these do not match because different sizes are mixed. Because it is done. On the other hand, if the determination in step S22 is affirmative, it is determined that the determination processing for all pages is completed without being determined to be negative in step S29, and the process proceeds to step S30 to set the variable PSA.
Set “1” to ME.

Next, details of the output tray setting process will be described with reference to FIG. In the figure, in step S40, it is determined whether the face-down tray 5 is designated as a tray. This is judged based on the output tray type which the operator has set in the RAM 16 by the control panel 7 in advance. However, if the determination in step S3 is negative, that is, if reception is in progress, the face-down tray 5 is forcibly selected regardless of the operator's input (step S11). If the face down tray 5 is designated, the process proceeds to step S41 to print from the first page, and "1" is set to the variable CN. In step S42, the FDW is sent to the printer unit 10.
Send N command. In step S43, the CN page is opened to obtain the page size. Step S4
At 4, the CN page is closed. Step S45
Then, the size attribute (A4 vertical, A4 horizontal, etc.) of the CN page is set in the variable PSIZE.

On the other hand, when the face down tray 5 is not designated, it is judged that the face up tray 4 is designated. Then, in order to print from the last page, the process proceeds from step S40 to step S46, and the variable CN is set to the variable CN indicating the number of pages of the document, that is, the number of last pages. In step S47, the printer unit 1
A FUP command is sent to 0 to set the face-up tray.

Next, details of the one-sided printing process will be described with reference to FIG.
Will be described with reference to. In step S50 in the figure, a SIMPLEX command is output to the printer unit 10 to set the sheet conveying device 6 in the single-sided printing state. In step S51, it is determined whether or not the variable PN is "0", and whether or not the last page of the received document has been processed, and R
It is determined whether XFLAG is "1". Step S52
Then, it is determined whether or not the variable PN is "0". File 1
When 2 becomes full, print output is started to release the memory, and when the print output is faster than the reception speed, it is conceivable that the data of the file 12 is less than one page. Therefore, step S52
Then, assuming such a case, the data amount of the received document is 1
Performs the process to wait until there are enough pages.

In step S53, the CN page is opened and the size of the page is obtained. In step S54, the recording paper of the size obtained in step S53 is pulled out from the recording paper tray. In step S55, CN page data is read by issuing a READ command to the file interface 13. In step S56, the print process is started by sending the PRT command to the printer unit 10. CN in step S57
The page is closed, and in step S58, PPURGE
Issuing a command to the file interface 13 and CN
Delete the page. As a result, the memory block of the file 12 used in the CN page is released.

In step S59, it is determined whether the face down tray 5 is designated. If the face-down tray 5 is specified, the variable C is set in step S60.
If N is incremented (+1) and the face down tray 5 is not designated, the variable C is determined in step S61.
N is decremented (-1). In step S62, the variable PN is decremented (-1). If the reception is completed and no received document remains, the determination in step S51 becomes affirmative, and the one-sided printing process ends.

Next, details of the double-sided printing process will be described. First, with reference to FIG. 10, an output form during double-sided printing will be described. In FIGS. 7A to 7D, the upper part shows the print page, the lower part shows the output form, and the numbers show the number of pages. FIG. 10A shows an output form in the case where the face down tray 5 is designated and the total number of pages is an even number (4 pages in this example). In this case, the pages are printed in the order of “page 2 to page 1 to page 4 to page 3”. As a result, one page is output so as to be the bottom surface, and the last page, that is, four pages is output as the top surface.
Further, FIG. 10B shows an output form in the case where the face down tray 5 is designated and the total number of pages is an odd number (5 pages in this example). In this case, the pages are printed in the order of "2 pages-1 page-4 pages-3 pages-dummy pages-5 pages". As a result, one page is output so as to be the bottom surface, and the last page, that is, page 5 is output as the top surface.

Similarly, FIG. 10C shows an output form when the face-up tray 4 is designated and the total number of pages is an even number (4 pages in this example). In this case, "4
Pages to 3 pages to 2 pages to 1 page ”are printed in this order. As a result, four pages are output so as to be the bottom surface, and the last page, that is, one page is output as the top surface. Further, FIG. 10D shows an output form in the case where the face-up tray 4 is designated and the total number of pages is an odd number (5 pages in this example). in this case,
Printing is performed in the order of "dummy page-5 page-4 page-3 page-2 page-1". As a result, the dummy page is output so as to be the bottom surface, and one page is output so as to be the top surface. In the printing of the dummy page, only the recording paper is conveyed in order to reverse the recording paper, and the process of actually forming no image is performed.

Next, the above-mentioned double-sided printing will be described with reference to the flowchart of FIG. In the figure, in step S70a, a DUPLEX command is output to the printer unit 10 to set the sheet conveying device 6 in the single-sided printing state. In step S70, it is determined whether the face down tray 5 is designated. If the face-down tray 5 is designated, it is determined in step S71 whether the total number of pages of the document to be processed is "0" or "1" or more. If the determination in step S71 is negative, the process proceeds to step S72, and the recording paper having the size attribute designated by the variable PSIZE is pulled out from the recording paper tray 2. In step S73, the variable CN is incremented (+1),
In step S74, print output processing for the CN page is executed. In this example, the second page is printed. Details of the printing process will be described later with reference to FIG. Step S
At 75, the variable CN is decremented (-1). In step S76, CN page printout processing is executed. In this example, the first page is printed. In step S77, the variable CN is incremented "+2".
Here, the variable CN is "3" and the variable CN is "4" in step S73 in the next cycle, so the fourth page is printed in step S74. Next, in step S75, the variable CN becomes “3”, and in step S76
Will print the third page. And step S77
With the variable CN set to "5", the process proceeds to step S71.

At this point, if the total number of pages is four, the variable PN becomes "0", so that the determination in step S71 becomes affirmative and the process proceeds to step S78. In step S78, it is determined whether the number of pages is "0" based on the variable PN. If the manuscript has a total of four pages, this judgment is affirmative and the processing is ended. In this way, print output is performed in the form of FIG.

Further, when the total number of pages is 5, the variable PN becomes "1" when printing is completed up to 4 pages, and in this case also, the determination in step S71 becomes affirmative and the process proceeds to step S78. Since the number of remaining pages, that is, the variable PN is "1", the determination in step S78 is negative, the process proceeds to step S79, the recording paper is pulled out, and dummy printing is performed in step S80. Step S81
Then, the CN page, that is, the fourth page is printed. In this way, print output is performed in the form of FIG.

On the other hand, if the face-up tray 4 is designated, the determination at step S70 becomes negative and the routine proceeds to step S82. In step S82, it is determined whether or not the variable PN is even (odd), and if it is odd, the process proceeds to step S83, and the recording paper having the size attribute designated by the variable PSIZE is pulled out. In step S84, dummy printing is performed. In step S85, CN page printout processing is performed. In this example, since the value of the variable PN is set in the variable CN, the final page is printed. In step S86, the variable CN is decremented (-1).
In step S87, it is determined whether the number of remaining pages is "0" by the variable PN. Until all pages have been printed, the determination in step S87 is negative and the process proceeds to step S88. In step S88, the recording paper is pulled out. In step S89, CN page print output processing is performed. Similarly, one page is printed in steps S90 and S91, and the variable CN is decremented (-1) in step S92. After that, step S
Pages are printed in descending order until the determination at 87 is negative. In this way, print output is performed in the form of FIG.

Furthermore, if the variable PN is an even number and the determination in step S82 is affirmative, steps S83 to S86 are performed.
Is skipped and the process proceeds to step S87. as a result,
Immediately after the recording paper is pulled out, the pages are printed in descending order from the last page. In this way, print output is performed in the form of FIG.

Next, the CN page printing process will be described with reference to the flowchart of FIG. In the figure, in step S100, a ROPEN command is issued to the file interface 13 to open the CN page. In step S101, it is determined whether or not there is a page corresponding to the variable CN. If there is a corresponding page, the size attribute of the page is "P" in step S102.
SIZE ”. When double-sided printing is executed, the sizes of the recording papers are the same, and different size attributes indicate that the orientations differ by 90 degrees. Therefore, if the determination in step S102 is negative, the process proceeds to step S103, and the ROT is set in the image rotation unit 9.
The 90 command is issued to specify the 90-degree rotation processing of the image. In step S104, the image image of the CN page is read out, and in step S105, print processing is started. That is, the PRT command is issued to the printer unit 10. In step S106, the CN page is closed. In step S107, the CN page is deleted. In step S108, the variable PN is decremented (-1).
To do. If the determination in step S101 is negative, the process proceeds to step S109 to perform dummy printing.

When the ROT 90 command is issued, the image rotation section 9 reads out image data as follows. FIG.
FIG. 3 is a diagram showing addresses and a reading order in the page memory 8. In the figure (a), the coordinates of the four corners of the image are (0,0), (0, Y), (X, 0),
(X, Y). At the time of writing the image image, the data of the number Y corresponding to the line synchronization (L.SYNC) is written in the direction indicated by the arrow for the number of lines X of the page synchronization (P.SYNC), starting from the coordinates (0,0). When the image image thus written is read by the ROT command 90, the coordinates (0,
(Y) as a starting point, the data of the number X corresponding to the line synchronization (L.SYNC) is read in the direction indicated by the arrow for the number of lines Y of the page synchronization (P.SYNC). The image image read in this way is supplied to the printer unit 10.

Next, the flow of the recording paper in the paper carrying device 6 will be described with reference to the block diagram of the paper carrying device 6. In FIG. 12, the recording sheets stacked on the recording sheet tray 2 are pulled out to the position of the registration sensor 21 by the feeding roller 19 and the pulling roller 20, and stand by. Then, in accordance with a print instruction, the image is transferred to the image transfer unit 22 to transfer the image, and further transferred to the image fixing unit 23 to be subjected to a fixing process. After that, when the single-sided / face-down tray is designated, the sheet is discharged to the face-down tray 5 through the path C1 selected by the solenoid 24. On the other hand, when the single-sided / face-up tray is designated, the second path is passed through the path C2 selected by the solenoid 24 and the face-up discharge clutch 25.
The sheet is discharged to the face-up tray 4 through the path C3 selected by the solenoid 26.

When double-sided printing is designated, after passing through the image fixing section 23, the sheet reaches the path C1 and is fed to a state where the trailing end portion is sandwiched by the discharge roll 27 and the reversing clutch 28. Then, the reversing clutch 28 performs a reversing operation, so that the recording sheet is conveyed to the path C2 with the trailing end portion up to now as the leading end. Then, the recording paper goes down the path C4 by the selection of the second solenoid 26, and is conveyed to the standby sensor 32 by the intermediate rolls 29, 30, 31 and stopped. Then, the image transfer unit 22 forms an image on the back side of the previously printed surface, and the image fixing unit 23 fixes the image. The recording paper on which fixing has been completed is discharged to either the face-down tray 5 or the face-up tray 4 based on the designation.

If a dummy print instruction, that is, a DUMMY command is issued while waiting at the position of the standby sensor 32, the recording paper is ejected without being printed on the back surface. Further, when printing only on the back surface of the recording paper, the DUM can be used while waiting at the registration sensor 21.
When the MY command is issued, printing is not performed, only the reversing operation of the recording sheet is performed and the recording sheet is conveyed to the position of the standby sensor 32.

[0048]

As is apparent from the above description, according to the inventions of claims 1 to 3, double-sided printing and single-sided printing do not coexist, so that the document formats after printing are unified and arranged. It will be easier. Further, the image is not forcibly reduced due to double-sided printing, and it is possible to prevent the printed document from being difficult to see.

In particular, according to the second aspect of the invention, even if there are pages with different orientations, if they have the same size by rotation, it is considered that all pages have the same size, In addition, the orientation of all pages is aligned by the image rotation means. Therefore, since the orientations are different, it is not judged that the sizes are different, so that it is not printed on a large size recording paper or forced to print on one side.

According to the third aspect of the invention, for example, when the memory becomes full during the reception of a large number of documents and printing is started to release the memory, the page size of the remaining documents is determined. Therefore, it is possible to prevent misalignment of print documents by unifying the single-sided printing.
