[Problems to be solved by the invention]
However, as described above, in the conventional image forming apparatus, when performing the duplex output control, the designation of the duplex mode such as the long side binding duplex mode designation or the short side binding duplex mode designation is performed on the entire document to be output. In contrast, the paper size (A3, A4, B4, B5, etc.) and the drawing direction (portrait drawing, landscape drawing) can be specified for each page. It is possible to specify a mixture of drawings for different sizes of paper.
[0010]
For this reason, in the conventional image forming apparatus, there are cases where the binding direction is inconsistent between the mixed paper sizes for the designation of double-sided output for the entire document.
[0011]
Hereinafter, a case where A4 size portrait drawing and A3 size landscape drawing coexist in the same document will be described with reference to FIGS.
[0012]
FIGS. 17A and 17B are schematic diagrams showing output results of portrait drawing 1 to 4 pages of A4 size long side feed paper. FIG. 17A shows a state where output results are bundled, and FIG. 3 shows a state where page 3 is opened.
[0013]
FIGS. 18A and 18B are schematic diagrams showing output results of landscape drawing 5 to 8 pages of A3 size short-side feed paper. FIG. 18A shows a state in which output results are bundled, and FIG. 18B shows output results 6 and 7. Shows the page opened.
[0014]
FIG. 19 shows the output result of the portrait drawing 1-4 pages of the A4 size long side feed paper shown in FIG. 17 and the output result of the landscape drawing 5-8 pages of the A3 size short side feed paper shown in FIG. It is a schematic diagram showing a bundled state, (a) shows a state where output results are bundled, (b) shows a state where pages 6 and 7 of the output results are opened, and “page 6” is bound upside down. ing.
[0015]
As shown in FIG. 19, A4 size paper is fed with long side feed (long edge feed) to print a portrait drawing, and A3 size paper is fed with short side feed (short edge feed). When printing with landscape drawing and bundling, the drawing direction of the front and back of A4 size paper and the drawing direction of the front and back of A3 size paper are different.
[0016]
This is because both A3 and A4 sizes are designated for drawing in the long-edge binding duplex mode. As shown in FIG. 19B, “6 pages, 8 pages (even pages) of A3 size paper”. Is bound upside down.
[0017]
On the other hand, a case is also considered in which short side binding (short edge binding) duplex mode is specified for a document, and A4 size portrait drawing and A3 size landscape drawing are mixed in the same document.
[0018]
In this case, since drawing is specified in the short-side binding duplex mode for both A3 and A4 sizes, two pages (even pages) of A4 size paper are bound upside down.
[0019]
As described above, in the conventional image forming apparatus, when the paper sizes are mixed, when the double-side binding direction is uniquely specified for the entire document, the binding position may be contradictory as a result.
[0020]
The present invention has been made to solve the above problems, and an object of the present invention is to obtain an optimal double-sided print output result that is aligned in the binding direction even when a plurality of paper sizes are mixed in the same document. It is to provide a mechanism that can acquire.

[0054]
In the figure, the connector 1001 of the core unit 10 is connected to the connector 120 of the reader unit 1 by a cable. The connector 1001 incorporates four types of signal lines 1051, 1052, 1057, and 1055, and the signal line 1051 is a signal line that communicates with the CPU 122 in the reader unit 1. The signal line 1052 is a signal line for communicating with the SUB / CPU 123 in the reader unit 1. The signal line 1057 is an 8-bit multi-value video signal line. A signal line 1055 is a control signal line for controlling the video signal.
[0055]
The signal line 1051 and the signal line 1052 are subjected to communication protocol processing by the communication IC 1002 and transmit communication information to the CPU 1003 via the CPU bus 1053. The CPU 1003 includes a ROM storing a control program and a RAM as a work area, and performs overall control (to be described later) of the core unit 10 according to the control program in the ROM.
[0056]
Note that the signal line 1057 is a bidirectional video signal line, and can receive information from the reader unit 1 by the core unit 10 and output information from the core unit 10 to the reader unit 1. Further, the signal line 1057 is connected to the buffer 1010, where the bidirectional signal is separated into the signal lines 1058 and 1070 for the one-way signal. A signal line 1058 is a signal line for an 8-bit multilevel video signal from the reader unit 1, and outputs an 8-bit multilevel video signal to a lookup table unit (hereinafter referred to as LUT) 1011 in the next stage.
[0057]
The LUT 1011 converts the image information from the reader unit 1 into a desired value using a lookup table. A signal on the output signal line 1059 from the LUT 1011 is input to the binarization circuit 1012 or the selector 1013. The binarization circuit 1012 has a simple binarization function for binarizing a multilevel signal on the signal line 1059 at a fixed slice level, and a binarization circuit with a slice level in which the slice level fluctuates from the values of pixels around the pixel of interest. It has a binarization function and a binarization function by an error diffusion method.
[0058]
The binarized information is converted into a multi-value signal of “00H” when “0” and “FFH” when “1”, and is input to the selector 1013 at the next stage. The selector 1013 selects either the signal from the LUT 1011 or the output signal of the binarization circuit 1012.

The signal (of signal line 1064) and the signal of output signal line 1060 of selector 1013 are selected by an instruction from CPU 1003.
[0060]
A signal on the output signal line 1061 of the selector 1014 is input to the rotation circuit 1015 or the selector 1016. The rotation circuit 1015 has a function of rotating the input image signal to “+90 degrees”, “−90 degrees”, and “+180 degrees”. The rotation circuit 1015 converts the information output from the reader unit 1 into a binary signal by the binarization circuit 1012, and then stores the information in the rotation circuit 1015 as information from the reader unit 1.
[0061]
Next, in response to an instruction from the CPU 1003, the rotation circuit 1015 rotates and reads the stored information. The selector 1016 selects one of the output signal line 1062 of the rotation circuit 1015 and the input signal line 1061 of the rotation circuit 1015, and a connector 1005 to the facsimile unit 4 and a connector to the file unit 5 as a signal of the signal line 1063. 1006, the connector 1007 with the computer interface unit 7, the connector 1008 with the formatter unit 8, the connector 1009 with the image memory unit 9, and the selector 1017.

The signal line 1064 is a synchronous 8-bit unidirectional video bus for transferring image information from the facsimile unit 4, the file unit 5, the computer interface unit 7, the formatter unit 8, and the image memory unit 9.
[0063]
Here, the video control circuit 1004 controls the synchronous bus between the signal line 1063 and the signal line 1064 by a signal on the output signal line 1056 from the video control circuit 1004. In addition, signal lines 1054 are connected to the connectors 1005 to 1009, respectively. A signal line 1054 is a bidirectional 16-bit CPU bus, and exchanges data commands in an asynchronous manner.
[0064]
Information transfer between the facsimile unit 4, the file unit 5, the computer interface unit 7, the formatter unit 8, the image memory unit 9 and the core unit 10 can be performed by the above two video buses 1063 and 1064 and the CPU bus 1054. .
[0065]
Further, signals on the signal line 1064 from the facsimile unit 4, the file unit 5, the computer interface unit 7, the formatter unit 8, and the image memory unit 9 are input to the selector 1014 and the selector 1017. The selector 1014 inputs the signal on the signal line 1064 to the rotation circuit 1015 at the next stage according to an instruction from the CPU 1003.
[0066]
The selector 1017 selects one of the signals on the signal line 1063 and the signal line 1064 according to an instruction from the CPU 1003. An output signal line 1065 of the selector 1017 is input to the pattern matching circuit 1018 and the selectors 1019 and 1021. The pattern matching circuit 1018 performs pattern matching on the signal of the input signal line 1065 with a predetermined pattern, and outputs a predetermined multi-value signal to the signal line 1066 when the patterns match. If the pattern matching does not match, the signal on the input signal line 1065 is output to the signal line 1066.
[0067]
The selector 1019 selects the signal line 1065 and the signal line 1066 according to an instruction from the CPU 1003. An output signal of the selector 1019 passes through a signal line 1067 and is input to a lookup table (LUT) 1020 at the next stage. The LUT 1020 converts the signal of the input signal line 1067 according to the characteristics of the printer when outputting image information to the printer unit 2.
[0068]
The selector 1021 selects one of the output signal line 1066 and the signal line 1065 of the LUT 1020 according to an instruction from the CPU 1003. The output signal of the selector 1021 is input to the next-stage expansion circuit 1022 via the signal line 1069. The enlargement circuit 1022 can set the enlargement magnification independently of the X direction and the Y direction of the image according to an instruction from the CPU 1003.
[0069]
The enlargement method is a first-order linear interpolation method. The output signal of the enlargement circuit 1022 is input to the buffer 1010 through the signal line 1070. A signal on the signal line 1070 input to the buffer 1010 is sent to the printer unit 2 via the connector 1001 through the bidirectional signal line 1057 according to an instruction from the CPU 1003 and printed out.

FIG. 5 is a block diagram illustrating the configuration of the computer interface unit 7 of the image forming apparatus shown in FIG.
[0071]
In the figure, reference numerals 704 and 708 denote SCSI interfaces (SCSII / F), 705 denotes a Centronics interface (Centronics I / F), and 706 denotes an RS232C interface (RS232CI / F). Do.
[0072]
Reference numerals 700 to 703 denote connectors to external devices (for example, PC / WS7A), which are connected to the interfaces 704, 708, 705, and 706 via signal lines 751, 752, and 753. A connector 707 is connected to the core unit 10 side and is connected to each interface 704, 708, 705, 706 via a signal line 754. Information from the computer interface unit 7 is transferred to the core unit 10 via the connector 707.
[0073]
Hereinafter, the flow of signals between the core unit 10 and each unit will be described.
[0074]
[Operation of Core Unit 10 by Information Transmission with Facsimile Unit 4]
First, a case where information is output from the core unit 10 to the facsimile unit 4 will be described.
[0075]
The CPU 1003 of the core unit 10 communicates with the CPU 122 of the reader unit 1 via the communication IC 1002 and issues a document scan command. The reader unit 1 reads a document by the scanner unit 104 scanning in accordance with this command, and outputs image information to the connector 120. The reader unit 1 and the external device 3 are connected by a cable, and information from the reader unit 1 is input to the connector 1001 of the core unit 10.
[0076]
The image information input to the connector 1001 of the core unit 10 is input to the buffer 1010 through the multi-value 8-bit signal line 1057. The buffer circuit 1010 inputs the signal of the bidirectional signal line 1057 as a one-way signal to the LUT 1011 through the signal line 1058 according to an instruction from the CPU 1003. The LUT 1011 converts the image information from the reader unit 1 into a desired value using a lookup table. For example, it is possible to remove the background of the document.
[0077]
The output signal of the LUT 1011 is input to the next-stage binarization circuit 1012 through the output signal line 1059. The binarization circuit 1012 converts the 8-bit multilevel signal on the signal line 1059 into a binarized signal. The binarization circuit 1012 converts the binarized signal into 00H when the signal is 0 and FFH when the signal is 1, and two multilevel signals. An output signal of the binarization circuit 1012 is input to the rotation circuit 1015 or the selector 1016 via the selector 1013 and the selector 1014.
[0078]
The output signal of the rotation circuit 1015 is also input to the selector 1016 via the signal line 1062, and the selector 1016 selects either the signal on the signal line 1061 or the signal on the signal line 1062. The selection of the signal is determined by the CPU 1003 communicating with the facsimile unit 4 via the CPU bus 1054.
[0079]
A signal on the output signal line 1063 from the selector 1016 is sent to the facsimile unit 4 via the connector 1005. The facsimile unit 4 can also store the received information in the hard disk 4A.
[0082]
In addition, when an image at the time of facsimile reception is output as it is to the printer unit 2 according to an instruction from the CPU 1003, the signal of the signal line 1064 input to the selector 1017 is input to the pattern matching circuit 1018.
[0083]
Next, the pattern matching circuit 1018 has a function of smoothing rattling of an image when receiving a facsimile. The pattern-matched signal is input to the LUT 1020 via the selector 1019. The LUT 1020 can change the table of the LUT 1020 by the CPU 1003 in order to output an image received by facsimile to the printer unit 2 at a desired density.
[0084]
A signal on the output signal line 1068 of the LUT 1020 is input to the enlargement circuit 1022 via the selector 1021. The enlargement circuit 1022 performs an enlargement process on the 8-bit multilevel signal having two values (“00H” and “FFH”) by a first-order linear interpolation method. The 8-bit multi-value signal having the value “00-FF” output from the enlargement circuit 1022 is sent to the reader unit 1 via the buffer 1010 and the connector 1001.
[0085]
The reader unit 1 inputs this signal to the external I / F switching circuit 119 via the connector 120. The external I / F switching circuit 119 inputs a signal from the facsimile unit 4 to the Y signal generation / color detection circuit 113. The output signal from the Y signal generation / color detection circuit 113 is processed as described above, and then output to the printer unit 2 to form an image on the output paper.
[0086]
[Operation of Core Unit 10 by Information Transmission with File Unit 5]
Hereinafter, a case where information is output from the core unit 10 to the file unit 5 will be described.
[0087]
The CPU 1003 of the core unit 10 communicates with the CPU 122 of the reader unit 1 via the communication IC 1002 and issues a document scan command. The reader unit 1 reads a document by the scanner unit 104 scanning in accordance with this command, and outputs image information to the connector 120.
[0088]
The reader unit 1 and the external device 3 are connected by a cable, and information from the reader unit 1 is input to the connector 1001 of the core unit 10. Image information input to the connector 1001 is input to the one-way signal line 1058 via the buffer 1010. A signal on the signal line 1058 which is an 8-bit multi-value signal is converted into a desired signal by the LUT 1011. An output signal of the LUT 1011 is input to the connector 1006 through the signal line 1059, the selector 1013, the selector 1014, and the selector 1016.
[0089]
That is, the 8-bit multivalue is transferred to the file unit 5 without using the functions of the binarization circuit 1012 and the rotation circuit 1015. When the binarized signal is filed by communication with the file unit 5 via the CPU bus 1054 of the CPU 1003, the binarization circuit 1012 and the rotation circuit 1015 have functions. Since the binarization process and the rotation process are the same as those of the facsimile unit 4 described above, a description thereof will be omitted.
[0090]
Next, a case where the core unit 10 receives information from the file unit 5 will be described.
[0091]
First, image information from the file unit 5 is input to the selector 1017 by the selector 1014 via the connector 1006 and the signal line 1064. In the case of 8-bit multi-value filing, it is possible to input to the selector 1017, and in the case of binary filing, it can be input to the selector 1014 or 1017. In the case of binary filing, the processing is the same as that of the facsimile unit 4, and thus the description thereof is omitted.
[0092]
In the case of multi-level filing, the output signal from the selector 1017 is binarized to the LUT 1020 via the signal line 1065 and the selector 1019. In the LUT 1020, a lookup table is created according to an instruction from the CPU 1003 in accordance with a desired print density. An output signal from the LUT 1020 is input to the enlargement circuit 1022 via the signal line 1068 and the selector 1021.
[0093]
The 8-bit multilevel signal 1070 expanded to a desired expansion ratio by the expansion circuit 1022 is sent to the reader unit 1 via the buffer 1010 and the connector 1001. The information of the file unit 5 sent to the reader unit 1 is output to the printer unit 2 and image formation is performed on the output paper, similarly to the facsimile unit 4 described above.
[0094]
[Operation of Core Unit 10 by Information Transmission with Computer Interface Unit 7]
The computer interface unit 7 performs an interface with the PC / WS 7 </ b> A connected to the external device 3. Information transferred to the core unit 10 via the connector 707 of the computer interface unit 7 is sent to the CPU 1003 via the connector 1007 and the data bus 1054. The CPU 1003 performs various controls based on the sent contents.
[0095]
[Operation of Core Unit 10 by Information Transmission with Formatter Unit 8]
The formatter unit 8 has a function of developing command data such as a document file from the PC / WS 7A sent from the computer interface unit 7 through the core unit 10 into image data.
[0096]
When the CPU 1003 of the core unit 10 determines that the data sent from the computer interface unit 7 via the data bus 1054 is data related to the formatter unit 8, the CPU 1003 transfers the data to the formatter unit 8 via the connector 1008. The formatter unit 8 develops the transferred data in the memory as a meaningful image such as a character or a figure.
[0097]
FIG. 6 is a block diagram illustrating the configuration of the formatter unit 8 of the image forming apparatus shown in FIG.
[0098]
In the figure, reference numeral 800 denotes a connector which is connected to the core unit 10. Reference numeral 803 denotes a dual-port memory that stores code data (code data transferred via the computer interface 7 and the core unit 10) from the PS / WS 7A transferred from the connector 800 via the data bus line 853. Reference numeral 809 denotes a CPU which receives code data sent from the PS / WS 7A via the dual port memory 803 via the CPU bus 857, temporarily stores the code data in the memory 805, and then sequentially develops it into image data. The image data is transferred to the memory A 806 or the memory B 807 via the memory controller 808.
[0099]
The memory A 806 and the memory B 807 each have a capacity of 1 Mbytes, and one memory (the memory A 806 or the memory B 807) supports (stores) up to A4 paper size data at a resolution of 300 dpi. Memory A 806 and memory B 807 are connected to memory controller 808 via data bus lines 858 and 859, respectively.
[0100]
The memory controller 808 controls the memory A 806 and the memory B 807 according to instructions from the CPU 809. Further, for example, in the case of supporting up to A3 paper with a resolution of 300 dpi, the memory A806 and the memory B807 are connected in cascade to control to expand the image data.
[0101]
Reference numeral 804 denotes a rotation circuit. When image data is expanded, when rotation of characters or graphics is necessary, the image data is rotated and then transferred to the memory A 806 or the memory B 807.
[0102]
When the development of the image data in the memory A 806 or the memory B 807 is completed under the control of the CPU 809, the memory controller 808 uses the data bus line 858 of the memory A 806 or the data bus line 859 of the memory B 807 as the output line of the memory controller 808. Connect to 851.
[0103]
A timing generation circuit 802 outputs a timing signal for reading image information from the memory A 806 or the memory B 807 to the memory controller 808 in accordance with a signal from the core unit 10 input via the connector 800 and the signal line 852. Output to memory controller 808 via line 856.
[0104]
The connector 800 transfers output image information from the memory controller 808 transferred via the signal line 851 to the core unit 10.
[0105]
Note that the memory 805 includes a program memory in which a program executed by the CPU 809 is stored.
[0106]
Hereinafter, the operation of each unit will be described.
[0107]
First, the data from the computer interface unit 7 is determined by the core unit 10, and when the data is related to the formatter unit 8, the CPU 1003 of the core unit 10 connects the connector 1008 of the core unit 10 and the connector 800 of the formatter unit 9. Then, data from the computer is transferred to the dual port memory 803.
[0108]
The CPU 809 of the formatter unit 8 receives code data sent from the computer via the dual port memory 803. The CPU 809 temporarily stores the code data in the memory 805 and then sequentially develops the code data into image data, and transfers the image data to the memory A 806 or the memory B 807 via the memory controller 808.
[0109]
When the image data is expanded, if rotation of characters, graphics, or the like is necessary, the image data is rotated by the rotation circuit 804 and then transferred to the memory A 806 or the memory B 807. When the development of the image data in the memory A 806 or the memory B 807 is finished, the CPU 809 controls the memory controller 808 to connect the data bus line 858 of the memory A 806 or the data bus line 859 of the memory B 807 to the output line 851 of the memory controller 808. .
[0110]
Next, the CPU 809 communicates with the CPU 1003 of the core unit 10 via the dual port memory 803 and sets the mode in which image information is output from the memory A 806 or the memory 807. The CPU 1003 of the core unit 10 sets a print output mode in the CPU 122 using a communication function built in the CPU 122 of the reader unit 1 via the communication circuit 1002 in the core unit 10.
[0111]
The operation of each unit when the print output mode is set will be described below.
[0112]
First, when the print output mode is set, the CPU 1003 of the core unit 10 activates the timing generation circuit 802 via the connector 1008 and the connector 800 of the formatter unit 8. The timing generation circuit 802 generates a timing signal for reading image information from the memory A 806 or the memory B 807 in the memory controller 808 in accordance with a signal from the core unit 10.
[0113]
Image information from the memory A 806 or the memory B 807 is input to the memory controller 808 via the signal line 858. Output image information from the memory controller 808 is transferred to the core unit 10 via the signal line 851 and the connector 800. The output from the core unit 10 to the printer unit is the same as that described in the core unit 10 and will not be described.
[0114]
Next, a procedure for receiving information from the formatter unit 8 and forming an image on output paper will be described.
[0115]
Image information from the formatter unit 8 is transmitted as a multi-value signal having two values (“00H” and “FFH”) to the signal line 1064 via the connector 1008. A signal on the signal line 1064 is input to the selector 1014 and the selector 1017. The CPU 1003 controls the selectors 1014 and 1017. Thereafter, since it is the same as the case of the facsimile unit 4 described above, the description thereof is omitted.
[0116]
Next, the operation when printing a document in which a plurality of sizes of paper are mixed and designated for double-sided printing using the formatter unit 8 will be described with particular attention to the image drawing direction.
[0117]
The external PC / WS 7A and the reader unit 1 (operation unit 124), for a document consisting of a plurality of pages that are desired to be output on both sides by the image forming apparatus, have a “short side binding duplex mode” or a “long side binding duplex mode” as the duplex mode. "Paper size" (A3, A4, B4, B5, etc.) and drawing direction (portrait drawing, landscape drawing) can be selected for each page. It is also possible to specify the stapling process in the duplex mode and to staple the output paper by the stapler 221.
[0118]
In this case, data necessary for image formation of a plurality of pages sent from the PC / WS 7A is passed to the formatter unit 8 via the interface unit 7 and the core unit 10. Further, data necessary for image formation of a plurality of pages configured by image data read by the CCD 109 of the reader unit 1 and each specified data specified by the operation unit 124 passes through the core unit 10 from the reader unit 1. Is passed to the formatter unit 8.
[0119]
Next, when the formatter unit 8 receives data for one job by the above-described procedure, it temporarily stores the data in the memory 805 and performs a printing operation (hereinafter shown in FIG. 7).
[0120]
The first print control operation of the image forming apparatus according to the present invention will be described below with reference to the flowchart of FIG.
[0121]
FIG. 7 is a flowchart for explaining the first printing control procedure of the image forming apparatus according to the present invention. When the CPU 809 of the formatter unit 8 receives data from the outside and stores it in the memory 805, it is stored in the memory 805. Execute based on the program to be executed. In addition, (1)-(17) shows each step.
[0122]
First, when data for one job is stored in the memory 805 of the formatter unit 8, it is determined whether or not the document printed by the job includes a double-sided printing page (1). If it is determined that it is not, normal printing is performed (17), the process of this flowchart is terminated, and the process returns to the state of waiting for the next data.
[0123]
On the other hand, if it is determined in step (1) that the document printed by the job includes a double-sided page, it is determined whether or not a plurality of paper sizes are included (2). When it is determined that the paper size is not included, normal printing is performed (17), the processing of this flowchart is terminated, and the process returns to a state of waiting for the next data.
[0124]
On the other hand, if it is determined in step (2) that the document printed by the job includes a plurality of paper sizes, 1 is substituted for variable N representing the current page (3), and the Nth page Is determined to be double-sided data (4). If it is determined that the data is not double-sided data (single-sided data), the Nth page is printed in the designated single-sided mode (8), and the process of step (13) is performed. move on.
[0125]
On the other hand, if it is determined in step (4) that the Nth page is double-sided data, it is determined whether or not the designated double-side mode is long edge binding (long-side binding double-side mode) (5). If it is determined, it is determined whether the Nth page has a paper size of short edge feed (short edge feed) (6).
[0126]
Here, the short edge feed paper size is, for example, A3 size, B4 size, and the like, and the long edge feed (long side feed) paper size is, for example, A4 size, B5 size, or the like.
[0127]
Note that, as described with reference to FIG. 16 in the section of the prior art, the short edge feed is a mode in which the short side of the paper is transported to the head, and the long edge feed is the paper length. In this mode, the side is transported starting from the side. (See FIG. 16).
[0128]
If it is determined in step (6) that the Nth page is the paper size of the short edge feed, the Nth page is printed with the short edge binding (short edge binding duplex mode) (9), and the process of step (13) is performed. move on.
[0129]
On the other hand, if it is determined in step (6) that the Nth page is not the short edge feed paper size (long edge feed paper size), the Nth page is printed in the designated duplex mode (10). The process proceeds to (13).
[0130]
On the other hand, if it is determined that the duplex mode specified in step (5) is not long edge binding (long side binding duplex mode), that is, short edge binding (short side binding duplex mode), the Nth page is a short edge feed. It is determined whether or not the sheet size is (7). If it is determined that the Nth page is a short edge feed sheet size, the Nth page is printed in the designated duplex mode (11), and step (13). Proceed to processing.
[0131]
On the other hand, if it is determined in step (7) that the Nth page is not the short edge feed paper size (long edge feed paper size), the Nth page is printed with the long edge binding (long edge binding duplex mode). (12) The process proceeds to step (13).
[0132]
Next, after printing the Nth page, it is determined whether or not the N page is the last page (13). If it is determined that the N page is not the last page, the variable N representing the current page is incremented (14). ), The process returns to step (4).
[0133]
On the other hand, if it is determined in step (13) that page N is the last page, it is determined whether or not binding processing (staple processing) is specified (15), and it is determined that binding processing is specified. If it is, the designated binding process is performed (16), the process of this flowchart is terminated, and the process returns to the state of waiting for the next data.
[0134]
On the other hand, if it is determined in step (15) that the binding process is not designated, the process of this flowchart is terminated and the process returns to a state of waiting for the next data.
[0135]
With the above processing, even when papers having different paper sizes are printed by designating the same duplex mode, it is possible to perform printing that is consistent with the binding direction.
[0136]
In steps (9) and (12), the image data is controlled so as not to follow the rotation designation data corresponding to each image data received together with a plurality of image data included in one job, and the image data is rotated. The process is performed without being based on the rotation designation data.
[0137]
On the other hand, in the steps (10) and (11) other than the above (steps (9) and (12)), the image data is controlled to follow the rotation designation data, and the rotation processing for the image data is performed as the rotation designation data. Based on.
[0138]
As a result, the orientation of the image when the rotation processing is performed without being based on the rotation designation data is different from the orientation of the image when the rotation processing is performed based on the rotation designation data (for example, described later). (See FIGS. 10C and 10D).
[0139]
FIG. 8 is a schematic diagram showing a printing result by the image printing control procedure shown in FIG.
[0140]
The document shown in the figure is an 8-page document, and is an output result when the first to fourth pages are designated as A4 portrait data and the fifth to eighth pages are designated as A3 landscape data. .
[0141]
(A) shows a state in which output results are bundled, (b) shows a state in which the sixth and seventh pages are opened from the state in which the output results shown in (a) are bundled, and as shown in FIG. Even when the A3 size is mixedly loaded, even when the binding function is executed, optimal double-sided printing is performed with no contradiction in the printing direction.
[0142]
As described above, even if both sides of the entire document are designated as short edge binding or long edge binding so that optimal double-sided printing is possible even when paper sizes are mixed, depending on the paper size, An optimal binding function can be provided by ignoring the specified drawing direction on both sides.
[0143]
It should be noted that the processing shown in the flowchart of FIG. 7 described above means that both sides of a job in which small size pages (for example, A4 size pages) and large size pages (for example, A3 size pages) coexist. When printing and binding edge printing are instructed, among the rotation designation for each page output from the driver, the rotation designation is not followed for a predetermined page. Hereinafter, it demonstrates in detail using FIGS. 9-13.
[0144]
FIG. 9 is a schematic diagram illustrating an example of a double-sided printing and binding edge printing instruction screen for a job in which a small size page (for example, an A4 size page) and a large size page (for example, an A3 size page) are mixed. , (A) corresponds to the case where the document size is set to “A4” and the print orientation is set to “vertical”, ie, “A4 portrait”, and (b) is the document size “A3” and the print orientation is “horizontal”. ”, That is,“ A3 landscape ”is set, and (c) indicates that the printing surface is“ both sides ”and the binding direction is“ long edge binding 1 (left long edge or upper long edge binding) ”, that is,“ long edge ”. This corresponds to the case of setting to “bind duplex mode”.
[0145]
For example, assume that the user has created a document for four pages using word processing software in the PC / WS 7A shown in FIG. 1 having a printer driver.
[0146]
Then, on the page setting screen on the word processor software, the original size and orientation of the first and second pages of the document are set to A4 portrait (see FIG. 9A), and the third and fourth pages are set. Assume that the document size and orientation are set to A3 landscape (see FIG. 9B).
[0147]
Next, as shown in FIG. 9C, on the PC / WS7A printer driver setting screen, double-sided printing is performed on a total of four pages of documents including a mixture of two A4 pages and two A3 pages. It is assumed that the user sets the long side binding setting, that is, the long side binding duplex mode.
[0148]
Thus, in one job, the paper size is set for each page (first page, second page, third page, fourth page) on the setting screen on the word processor software, and the long side The user can independently set the binding double-side mode or the short-side binding double-side mode for each job on the setting screen of the printer driver.
[0149]
When the four-page document is formed on the recording paper, the image on the first page is the front surface (first surface) of the first recording paper, and the image on the second page is the back surface of the first recording paper ( The second page), the third page image is formed on the front surface (first surface) of the second recording paper, and the fourth page image is formed on the back surface (second surface) of the second recording paper. To do.
[0150]
In addition, regarding the size of the output paper (that is, the size of the recording paper), unless the user specifies the output paper so as to faithfully reproduce the data created by the user on the word processing software, the optimum size based on the original size is determined. Automatically select the size.
[0151]
In this case, the size of the first recording paper (hereinafter referred to as recording paper A) is set to A4, which is the same as the original size of the first and second pages, and the size of the second recording paper (hereinafter referred to as recording paper B) is set to A4. A3 is the same as the original size of the third and fourth pages.
[0152]
When the operation mode set by the user is the long-side binding double-side mode, the driver sets the long side of the sheet to be imaged as the binding direction, and the printer forms an image on both sides of the sheet based on the binding direction. The driver instruction is output to the side together with the image data.
[0153]
The image data and rotation designation data included in the printer job sent from the driver on the PC / WS 7A shown in FIG. 1 to the image forming apparatus will be described below with reference to FIGS. In the following description, “long edge binding” will be described using “long edge binding 1” in FIG. 9C and “short edge binding” as “short edge binding” in FIG. 9C. The same applies to the case of “long side binding 2” and “short side binding 2” in FIG.
[0154]
FIG. 10 is a schematic diagram for explaining processing when various modes are selected (designated). Double-sided / long-edge binding is performed for a document of 4 pages in total including A4 portrait 2 pages and A3 landscape 2 pages. This corresponds to the case where the mode to be used (long-side binding double-side mode) is specified (printing surface: double-sided, binding direction: long-side binding 1 specified in FIG. 9C).
[0155]
First, the image rotation designation on the driver side on the PC / WS 7A will be described.
[0156]
FIG. 10A shows a document created by word processing software executed on the PC / WS7A, and corresponds to, for example, a document of 4 pages in total including 2 pages of A4 and 2 pages of A3 (see FIG. 9). ).
[0157]
FIG. 10B shows an instruction from the driver based on the double-sided / long-edge binding (long-side binding double-sided mode) setting.
[0158]
The recording paper A as the output paper is a long edge feed sheet, that is, a sheet of the type conveyed with the long side of the sheet as the head, and the recording paper B is a short edge feed sheet, ie, a sheet. The sheet is of the type conveyed with the short side of the head as the head.
[0159]
Specifically, since the long side of the first recording sheet A is the left side (left end) of the sheet when the first side is used as a reference, the user can start from the first side of the recording sheet A. Rotate the first page image so that the second page image is formed upright when the second side of the recording paper A is viewed upside down with the left end (binding edge) as an axis. The designation is 0 degree, and similarly, the rotation designation of the image on the second page is also 0 degree. The rotation designation of these images is output to the printer side as a driver instruction.
[0160]
On the other hand, the long side of the second recording sheet B is the upper side (upper end) of the sheet when the first surface is used as a reference. Therefore, when the user flips the recording sheet B from the first side to the second side with reference to the upper end of the recording sheet B and looks at the second side of the recording sheet B, the image on the fourth page is upright. The rotation designation of the image on the third page is set to 0 degrees and the rotation designation of the image on the fourth page is set to 180 degrees, so that the rotation designation of these images is output to the printer side as a driver instruction.
[0161]
Thus, the rotation designation of the image from the driver is set for each page (in this case, 1st page, 2nd page, 3rd page, 4th page).
[0162]
Next, processing on the printer side will be described.
[0163]
FIG. 10C shows an output result (recording sheets A and B) when image rotation processing is performed based on an instruction from the driver shown in FIG. (D) shows output results (recording sheets A and B) when image forming processing is performed without following the driver instruction shown in FIG. A state of the sheet bundle when the recording sheets A and B are collected as one sheet bundle by the user is shown.
[0164]
When combining a plurality of sheets having different sizes as one sheet bundle, for example, it is conceivable to align the directions of the sheets in a direction in which the lengths in the binding direction coincide.
[0165]
That is, in this case, the length in the long side direction of the recording paper A and the length in the short side direction of the recording paper B coincide with each other, so that the recording paper A and the short side of the recording paper B overlap each other. Are aligned (see FIGS. 10C and 10D).
[0166]
This is not limited to the case where the user collects the data by himself / herself, but is automatically processed on the printer side (for example, the recording paper A is output with the orientation of the recording papers aligned so that the long side of the recording paper A and the short side of the recording paper B overlap). Even if it is a case, it is thought that it is put together similarly.
[0167]
As a result, the binding direction of the sheet bundle is the left side (left end portion) of the sheet when viewed from the first surface. When the recording sheets A and B are combined as one sheet bundle, the recording sheet The binding direction of A is the long side direction, which is the same direction as the binding direction determined in the driver setting, but the binding direction of the recording paper B is the short side direction and the binding direction (long side determined in the driver setting) Direction).
[0168]
On the other hand, the rotation designation of the image output from the driver to the printer is a rotation designation based on the binding direction set by the driver. For example, as shown in FIG. The rotation instruction is output to the printer for each page based on the long side direction.
[0169]
In this way, although the recording paper B should be aligned in a binding direction different from the binding direction set on the driver side, image rotation processing is performed for each page as instructed by the driver to form an image. In this case, as shown in FIG. 10C, the orientation of the image of the fourth page formed on the second surface of the recording paper B is 180 degrees different from the orientation of the image formed on the other surface. When the user turns the recording paper one by one with reference to the left end of the sheet bundle and sees the image on the fourth page, the orientation of the other images is upside down, making it difficult to view.
[0170]
In the present embodiment, in order to prevent the occurrence of such a problem, out of the rotation designation for each page output from the driver, the rotation designation for a predetermined page (here, 180 degrees with respect to the image on the fourth page). The CPU 809 controls to follow the rotation designation for other pages.
[0171]
For example, in this case, as shown in FIG. 10B, an instruction to rotate the image of the fourth page to be formed on the second surface of the recording paper B is output from the driver to the printer as an instruction to rotate 180 degrees. However, the printer side does not follow the rotation designation from the driver corresponding to the page, and does not perform the rotation process on the image of the fourth page, and the image of the fourth page on the second surface of the recording paper B as it is. Control to form.
[0172]
On the other hand, according to the rotation designation of the images of the first page, the second page, and the third page, the image is rotated based on the rotation designation corresponding to each page of the first page, the second page, and the third page. Control to perform processing.
[0173]
That is, the CPU 809 predicts that the orientation of each recording sheet is aligned so that the long side of the recording sheet A and the short side of the recording sheet B overlap as processing for aligning the binding direction, and the predetermined output outputted from the driver. Ignoring the rotation designation data relating to the page, the rotation designation data is newly set on the printer side, and the image is rotated according to the rotation designation data.
[0174]
In anticipation, the CPU 809 acquires data relating to the document size and image orientation of the document, the size of the recording paper, the length in the long side direction and the short side direction of the recording paper on which the image is to be formed, and the like in advance. By referring to the stored table, the binding direction of the sheet bundle when it is combined as one bundle is determined (in this case, the left end portion), and the binding direction of each sheet at that time is checked (for example, this In this case, it is determined that the binding direction of the recording paper A is the same long side direction as the driver setting, and the binding direction of the recording paper B is determined to be a short side direction different from the driver setting), based on these The rotation designation data corresponding to each image data is set.
[0175]
For example, in this case, the rotation designation of the image of the fourth page set to 180 degrees on the driver side is reset to 0 degrees on the printer side.
[0176]
As described above, as shown in FIG. 10D, the orientation of the image of the fourth page formed on the second surface of the recording paper B is the same as the orientation of the image formed on the other surface. , Prevents the user from turning over the recording sheet one by one with reference to the left end of the sheet bundle and seeing the image on the fourth page, which makes it difficult to see the other images upside down. it can.
[0177]
FIG. 11 is a schematic diagram for explaining the processing when various modes are selected (designated). Double-sided / long-edge binding is performed for a document of 4 pages in total including A4 horizontal 2 pages and A3 vertical 2 pages. This corresponds to the case where the mode to be used (long-side binding double-side mode) is specified (printing surface: double-sided, binding direction: long-side binding 1 specified in FIG. 9C). Here, the recording paper A as output paper is a short edge feed sheet and B is a long edge feed sheet.
[0178]
First, the image rotation designation on the driver side on the PC / WS 7A will be described.
[0179]
FIG. 11A shows a document created by word processing software executed on the PC / WS 7A. Here, the document corresponds to a document of a total of 4 pages in which A4 horizontal 2 pages and A3 vertical 2 pages coexist.
[0180]
FIG. 11B shows an instruction from the driver based on the double-sided / long-edge binding (long-side binding double-sided mode) setting.
[0181]
Specifically, since the long side of the first recording sheet A is the upper side (upper end) of the sheet when the first side is used as a reference, the user can start from the first side of the recording sheet A. Rotate the first page image so that the second page image is formed upright when the second side of the recording paper A is viewed upside down with the upper end (binding edge) as an axis. The designation is 0 degree, the rotation designation of the second page image is 180 degrees, and the rotation designation of these images is output to the printer side as a driver instruction.
[0182]
On the other hand, the long side of the second recording sheet B is the left side (left end) of the sheet when the first side is used as a reference. Therefore, when the user turns over from the first surface of the recording paper B to the second surface with the left end as a reference and looks at the second surface of the recording paper B, the image on the fourth page is upright. The rotation designation of the image on the third page is set to 0 degrees so that the image is formed in the state, and similarly, the rotation designation of the image on the fourth page is set to 0 degrees. The
[0183]
Thus, the rotation designation of the image from the driver is set for each page (in this case, 1st page, 2nd page, 3rd page, 4th page).
[0184]
Next, processing on the printer side will be described.
[0185]
FIG. 11C illustrates an output result (recording sheets A and B) when image rotation processing is performed based on an instruction from the driver illustrated in FIG. ) Shows the output results (recording papers A and B) when the image forming process is performed without following the driver instruction shown in (b) with respect to the rotation designation of a predetermined page. A state of the sheet bundle when the user collects the sheet bundle as one sheet is shown.
[0186]
As described above, when a plurality of sheets having different sizes are collected as one sheet bundle, for example, it is conceivable to align the directions of the sheets in a direction in which the lengths in the binding direction match.
[0187]
In this case, since the length in the long side direction of the recording paper A matches the length in the short side direction of the recording paper B, the orientation of each recording paper is such that the long side of the recording paper A and the short side of the recording paper B overlap. Are aligned (see FIGS. 11C and 11D).
[0188]
Thus, the binding direction of the sheet bundle is the upper side (upper end portion) of the sheet when viewed from the first surface, and the recording sheets A and B are combined into a single sheet bundle. The binding direction of A is the long side direction, which is the same direction as the binding direction determined in the driver setting, but the binding direction of the recording paper B is the short side direction and the binding direction (long side determined in the driver setting) Direction).
[0189]
On the other hand, the rotation designation of the image output from the driver to the printer is a rotation designation based on the binding direction set by the driver. For example, as shown in FIG. The rotation instruction is output to the printer for each page based on the long side direction.
[0190]
In this way, although the recording paper B should be aligned in a binding direction different from the binding direction set on the driver side, image rotation processing is performed for each page as instructed by the driver to form an image. In this case, as shown in FIG. 11C, the orientation of the image on the fourth page formed on the second surface of the recording paper B is 180 degrees different from the orientation of the image formed on the other surface, When the user turns the recording sheet one by one with reference to the upper end of the sheet bundle and sees the image on the fourth page, the orientation of the other images is upside down, making it difficult to view.
[0191]
In the present embodiment, in order to prevent such a problem from occurring, out of the rotation designation for each page output from the driver, the rotation designation for a predetermined page (here, 0 degrees with respect to the image of the fourth page) The CPU 809 controls to follow the rotation designation for other pages.
[0192]
For example, in this case, as shown in (b), as the rotation designation of the image of the fourth page to be formed on the second surface of the recording paper B from the driver, an instruction to rotate 0 degree (that is, not rotate) is issued on the printer However, the printer side does not follow the rotation designation from the driver corresponding to the page, and rotates the fourth page image by 180 degrees as a unique rotation process not based on the rotation designation from the driver. Then, control is performed so that an image is formed on the second surface of the recording paper B.
[0193]
On the other hand, according to the rotation designation of the images of the first page, the second page, and the third page, the image is rotated based on the rotation designation corresponding to each page of the first page, the second page, and the third page. Control to perform processing.
[0194]
That is, the CPU 809 predicts that the orientation of each recording sheet is aligned so that the long side of the recording sheet A and the short side of the recording sheet B overlap as processing for aligning the binding direction, and the predetermined output outputted from the driver. Ignoring the rotation designation data relating to the page, the printer side newly sets the rotation designation data, and performs the rotation processing of the original image according to the rotation designation data.
[0195]
In anticipation, the CPU 809 acquires data relating to the document size and image orientation of the document, the size of the recording paper, the length in the long side direction and the short side direction of the recording paper on which the image is to be formed, and the like in advance. With reference to the stored table, the binding direction of the sheet bundle when it is combined as one bundle is determined (in this case, the upper end portion), and the binding direction of each sheet at that time is checked (for example, this In this case, it is determined that the binding direction of the recording paper A is the same long side direction as the driver setting, and the binding direction of the recording paper B is determined to be a short side direction different from the driver setting), based on these Then, the rotation designation data relating to the predetermined page output from the driver is ignored, the rotation designation data is newly set on the printer side, and the image is rotated according to the rotation designation data. For example, in this case, the rotation designation of the fourth page image set to 0 degrees on the driver side is reset to 180 degrees on the printer side, and the process of rotating the fourth page image by 180 degrees is performed. The image of the page is formed on the second surface of the recording paper B.
[0196]
Thus, as shown in FIG. 11D, the orientation of the image of the fourth page formed on the second surface of the recording paper B is the same as the orientation of the image formed on the other surface. , Prevents the user from turning over the recording paper one by one with reference to the upper end of the sheet bundle and seeing the image on the fourth page, which makes it difficult to see the other images upside down. it can.
[0197]
FIG. 12 is a schematic diagram for explaining the processing when various modes are selected (designated). For a document with 4 pages in total, which includes a total of 4 pages in which 2 pages in A4 length and 2 pages in A3 width are mixed. This corresponds to the case where the mode for double-sided / short-edge binding (short-side binding double-sided mode) is specified (printing surface: double-sided, binding direction: short-side 1 specified in FIG. 9C). Note that recording paper A as output paper is a long edge feed sheet and B is a short edge feed sheet.
[0198]
First, the image rotation designation on the driver side on the PC / WS 7A will be described.
[0199]
FIG. 12A shows a document created by word processing software executed on the PC / WS 7A, and corresponds to, for example, a document with a total of 4 pages in which A4 vertical 2 pages and A3 horizontal 2 pages coexist.
[0200]
FIG. 12B shows an instruction from the driver based on the double-sided / short-edge binding (short-side binding double-sided mode) setting.
[0201]
Specifically, since the short side of the first recording sheet A is the upper side (upper end) of the sheet when the first side is used as a reference, the user can start from the first side of the recording sheet A. Rotate the first page image so that the second page image is formed upright when the second side of the recording paper A is viewed upside down with the upper end (binding edge) as an axis. The designation is 0 degree, the rotation designation of the second page image is 180 degrees, and the rotation designation of these images is output to the printer side as a driver instruction.
[0202]
On the other hand, the long side of the second recording sheet B is the left side (left end) of the sheet when the first side is used as a reference. Therefore, when the user turns over from the first surface of the recording paper B to the second surface with the left end as a reference and looks at the second surface of the recording paper B, the image on the fourth page is upright. The rotation designation of the image on the third page is set to 0 degrees so that the image is formed in the state, and similarly, the rotation designation of the image on the fourth page is set to 0 degrees. The
[0203]
Thus, the rotation designation of the image from the driver is set for each page (in this case, 1st page, 2nd page, 3rd page, 4th page).
[0204]
Next, processing on the printer side will be described.
[0205]
FIG. 12C shows an output result (recording sheets A and B) when image rotation processing is performed based on an instruction from the driver shown in FIG. ) Indicates output results (recording sheets A and B) when image forming processing is performed without following the driver instruction shown in FIG. A state of the sheet bundle when the user collects B as one sheet bundle is shown.
[0206]
As described above, when a plurality of sheets having different sizes are collected as one sheet bundle, for example, it is conceivable to align the directions of the sheets in a direction in which the lengths in the binding direction match.
[0207]
In this case, since the length in the long side direction of the recording paper A matches the length in the short side direction of the recording paper B, the orientation of each recording paper is such that the long side of the recording paper A and the short side of the recording paper B overlap. Are aligned (see FIGS. 12C and 12D).
[0208]
As a result, the binding direction of the sheet bundle is the left side (left end portion) of the sheet when viewed from the first surface. When the recording sheets A and B are combined as one sheet bundle, the recording sheet The binding direction of B is the short side direction, which is the same direction as the binding direction determined in the driver setting, but the binding direction of the recording paper A is the long side direction, and the binding direction (short side) determined in the driver setting Direction).
[0209]
On the other hand, the rotation designation of the image output from the driver to the printer is a rotation designation based on the binding direction set by the driver. For example, as shown in FIG. The rotation instruction is output to the printer for each page based on the short side direction.
[0210]
In this way, although the recording paper A should be aligned in a binding direction different from the binding direction set on the driver side, image rotation processing is performed for each page according to the driver's instructions and image formation is performed. In this case, as shown in FIG. 12C, the orientation of the second page image formed on the second surface of the recording paper A is 180 degrees different from the orientation of the image formed on the other surface, When the user turns the recording paper one by one with reference to the left end of the sheet bundle and sees the image on the second page, the orientation of the other images is upside down, making it difficult to view.
[0211]
In the present embodiment, in order to prevent the occurrence of such a problem, out of the rotation designation for each page output from the driver, the rotation designation for a predetermined page (here, 180 degrees with respect to the image of the second page). The CPU 809 controls to follow the rotation designation for other pages.
[0212]
For example, in this case, as shown in FIG. 12B, an instruction to rotate the image by 180 degrees is output from the driver to the printer as the rotation designation of the second page image to be formed on the second surface of the recording paper A. However, on the printer side, without following the rotation designation from the driver corresponding to the page, the image on the second page is rotated by 0 degree (that is, without rotation) to form an image on the second surface of the recording paper A. Control to do.
[0213]
On the other hand, according to the rotation designation of the first page, the third page, and the fourth page, the image is rotated based on the rotation designation corresponding to each page of the first page, the third page, and the fourth page. Control to perform processing.
[0214]
That is, the CPU 809 predicts that the orientation of each recording sheet is aligned so that the long side of the recording sheet A and the short side of the recording sheet B overlap as processing for aligning the binding direction, and the predetermined output outputted from the driver. Ignoring the rotation designation data relating to the page, the printer side newly sets the rotation designation data, and performs the rotation processing of the original image according to the rotation designation data.
[0215]
In anticipation, the CPU 809 acquires data relating to the document size and image orientation of the document, the size of the recording paper, the length in the long side direction and the short side direction of the recording paper on which the image is to be formed, and the like in advance. By referring to the stored table, the binding direction of the sheet bundle when it is combined as one bundle is determined (in this case, the left end portion), and the binding direction of each sheet at that time is checked (for example, this In this case, it is determined that the binding direction of the recording sheet A is the long side direction different from the driver setting, and the binding direction of the recording sheet B is determined to be the same long side direction as the driver setting). In addition, the rotation designation data relating to the predetermined page output from the driver is ignored (not following the rotation designation relating to the predetermined page), the rotation designation data is newly set on the printer side, and the rotation designation data is added to the rotation designation data. According to picture Perform a rotation process. For example, in this case, the rotation designation of the second page image set to 180 degrees on the driver side is reset to 0 degrees on the printer side, and the second page image is rotated by 0 degrees (second page). The second page image is controlled to be formed on the second side of the recording sheet A as it is without performing the rotation process on the second image), and the processed second page image is formed on the second side of the recording sheet A. .
[0216]
Thus, as shown in FIG. 12D, the orientation of the image of the second page formed on the second surface of the recording paper A is the same as the orientation of the image formed on the other surface. Therefore, when the user turns the recording sheet one by one with reference to the left end portion of the sheet bundle and sees the image on the second page, it may be difficult to see the other image orientation and upside down. Can be prevented.
[0217]
FIG. 13 is a schematic diagram for explaining processing when various modes are selected (designated). Double-sided / short-edge binding is performed for a document of 4 pages in total including A4 horizontal 2 pages and A3 vertical 2 pages. This corresponds to the case where the mode to be used (short-side binding double-side mode) is designated (printing surface: double-sided, binding direction: short-side 1 designation in FIG. 9C). Here, the recording paper A as the recording paper is short edge feed, and the recording paper B is long edge feed.
[0218]
First, the image rotation designation on the driver side on the PC / WS 7A will be described.
[0219]
FIG. 13A shows a document created by word processing software executed on the PC / WS 7A. Here, the document corresponds to a document of a total of 4 pages in which A4 horizontal 2 pages and A3 vertical 2 pages coexist.
[0220]
FIG. 13B shows a driver instruction based on the double-sided / short-edge binding (short-side binding double-sided mode) setting.
[0221]
Specifically, since the short side of the first recording sheet A is the left side (left end) of the sheet when the first side is used as a reference, the user can start from the first side of the recording sheet A. Rotate the first page image so that the second page image is formed upright when the second side of the recording paper A is viewed upside down with the left end (binding edge) as an axis. The designation is set to 0 degree, the rotation designation of the image on the second page is set to 0 degree, and the rotation designation of these images is output to the printer side as a driver instruction.
[0222]
On the other hand, the short side of the second recording sheet B is the upper side (upper end) of the sheet when the first side is used as a reference. Therefore, when the user flips the recording sheet B from the first side to the second side with reference to the upper end of the recording sheet B and looks at the second side of the recording sheet B, the image on the fourth page is upright. The rotation designation of the image on the third page is set to 0 degrees and the rotation designation of the image on the fourth page is set to 180 degrees, so that the rotation designation of these images is output to the printer side as a driver instruction.
[0223]
Thus, the rotation designation of the image from the driver is set for each page (in this case, 1st page, 2nd page, 3rd page, 4th page).
[0224]
Next, processing on the printer side will be described.
[0225]
FIG. 13C shows an output result (recording sheets A and B) when image rotation processing is performed based on an instruction from the driver shown in FIG. ) Shows the output results (recording papers A and B) when the image forming process is performed without following the driver instruction shown in FIG. A state of the sheet bundle when the user collects B as one sheet bundle is shown.
[0226]
As described above, when a plurality of sheets having different sizes are collected as one sheet bundle, for example, it is conceivable to align the directions of the sheets in a direction in which the lengths in the binding direction match.
[0227]
In this case, since the length in the long side direction of the recording paper A matches the length in the short side direction of the recording paper B, the orientation of each recording paper is such that the long side of the recording paper A and the short side of the recording paper B overlap. Are aligned (see FIGS. 13C and 13D).
[0228]
Thus, the binding direction of the sheet bundle is the upper side (upper end portion) of the sheet when viewed from the first surface, and the recording sheets A and B are combined into a single sheet bundle. The binding direction of B is the short side direction, which is the same direction as the binding direction determined in the driver setting, but the binding direction of the recording paper A is the long side direction, and the binding direction (short side) determined in the driver setting Direction).
[0229]
On the other hand, the rotation designation of the image output from the driver to the printer is a rotation designation based on the binding direction set by the driver. For example, as shown in FIG. The rotation instruction is output to the printer for each page based on the short side direction.
[0230]
In this way, although the recording paper A should be aligned in a binding direction different from the binding direction set on the driver side, image rotation processing is performed for each page according to the driver's instructions and image formation is performed. In this case, as shown in FIG. 13C, the orientation of the second page image formed on the second surface of the recording paper A is 180 degrees different from the orientation of the image formed on the other surface. When the user turns the recording sheet one by one with respect to the upper end of the sheet bundle and sees the image on the second page, the orientation of the other images is upside down, making it difficult to view.
[0231]
In the present embodiment, in order to prevent the occurrence of such a problem, out of the rotation designation for each page output from the driver, the rotation designation for a predetermined page (here, 0 degrees with respect to the image of the second page) The CPU 809 controls to follow the rotation designation for other pages.
[0232]
For example, in this case, as shown in FIG. 13B, an instruction to rotate the second page image to be formed on the second surface of the recording sheet A is output from the driver to the printer side as 0 degrees. However, the printer side does not follow the rotation designation from the driver corresponding to the page, but performs the rotation of the image on the second page by 180 degrees as a unique rotation process not based on the rotation designation from the driver. Then, control is performed so that an image is formed on the second surface of the recording paper A.
[0233]
On the other hand, according to the rotation designation of the first page, the third page, and the fourth page, the image is rotated based on the rotation designation corresponding to each page of the first page, the third page, and the fourth page. Control to perform processing.
[0234]
That is, the CPU 809 predicts that the orientation of each recording sheet is aligned so that the long side of the recording sheet A and the short side of the recording sheet B overlap as processing for aligning the binding direction, and the predetermined output outputted from the driver. Ignoring the rotation designation data relating to the page, the printer side newly sets the rotation designation data, and performs the rotation processing of the original image according to the rotation designation data.
[0235]
In anticipation, the CPU 809 acquires data relating to the document size and image orientation of the document, the size of the recording paper, the length in the long side direction and the short side direction of the recording paper on which the image is to be formed, and the like in advance. With reference to the stored table, the binding direction of the sheet bundle when it is combined as one bundle is determined (in this case, the upper end portion), and the binding direction of each sheet at that time is checked (for example, this In this case, it is determined that the binding direction of the recording paper A is the long side direction different from the driver setting, and the binding direction of the recording paper B is determined to be the same short side direction as the driver setting), based on these Ignoring the rotation designation data output from the driver for the predetermined page (not following the rotation designation for the predetermined page), reset the rotation designation data on the printer side, and according to the rotation designation data Image times Processing is carried out. For example, in this case, the rotation designation of the second page image set to 0 degree on the driver side is reset to 180 degrees on the printer side, and the process of rotating the second page image by 180 degrees is performed. The image of the page is formed on the second surface of the recording paper A.
[0236]
As described above, as shown in FIG. 13D, the orientation of the second page image formed on the second surface of the recording paper A is the same as the orientation of the image formed on the other surface. , Prevents the user from turning over the recording sheet one by one with reference to the top edge of the sheet bundle and seeing the image on the second page, which makes it difficult to see the other images upside down. it can.
[0237]
As described above, either a long edge binding (long edge binding duplex mode) or a short edge binding (short edge binding duplex mode) is set for a job in which small and large pages are mixed. In this case, control is performed so as not to follow the rotation specification related to a predetermined page among the rotation specifications for each page output from the driver, so even if a plurality of paper sizes are mixed in the same document, the alignment is performed in the binding direction. The optimal double-sided printing output result can be acquired.
[0238]
As described with reference to FIGS. 9 to 13, in the present embodiment, the case where processing for aligning in the binding direction is performed on the printer side has been described. You may comprise so that the process for matching may be performed.
[0239]
For example, in the printer driver setting screen (see FIG. 9), when the long side binding setting is performed by the user, the driver matches the rotation specification of the large size page with the binding direction of the small size page. Take instructions.
[0240]
Hereinafter, a description will be given using the example shown in FIG.
[0241]
If the driver does not perform processing for aligning in the binding direction, as described above, the fourth page image is rotated 180 degrees as the rotation designation of the fourth page image formed on the second surface of the recording paper B. The driver's instruction is output to the printer side so as to perform the processing (see FIG. 10B).
[0242]
In this case, if the printer does not perform processing for aligning in the binding direction, the orientation of the image on the fourth page formed on the second surface of the recording paper B is other as shown in FIG. This is 180 degrees different from the orientation of the image formed on the surface.
[0243]
On the other hand, when the driver performs processing for aligning in the binding direction, the rotation designation of the fourth page image formed on the second surface of the recording paper B, which is an A3 size sheet (that is, the rotation of the large size page). Is set to the same rotation specification as the rotation specification of the second page image formed on the second surface of the recording paper A, which is an A4 size sheet (that is, the rotation specification of the small size page).
[0244]
Therefore, in this case, the driver sets the rotation designation for the image on the fourth page to 0 degrees, which is the same as the rotation designation for the image on the second page, and outputs the rotation designation to the printer as a driver instruction.
[0245]
That is, as a process of aligning the binding direction in the binding direction, when a plurality of sheets having different sizes are collected as one bundle, the orientation of each sheet is set so that the short side of the large size sheet and the long side of the small size sheet overlap. Rotation designation data that is expected to be aligned is set for each image data.
[0246]
When a plurality of sheets having different sizes are collected as one bundle, a driver is expected to align the orientation of each sheet so that the short side of the large sheet overlaps the long side of the small sheet. Is predicted by the same method as that performed on the printer side.
[0247]
On the other hand, when the driver side has already performed processing for aligning in the binding direction, the printer side may perform image rotation processing according to the driver's instruction to form an image.
[0248]
As a result, the orientation of the four-page image formed on the second surface of the recording paper B is the same as the orientation of the image formed on the other surface, so that a plurality of paper sizes are mixed in the same document. Even in this case, it is possible to output an optimum double-sided printing result aligned with the binding direction (see FIG. 10D).
[0249]
Therefore, for example, when the user turns the recording sheet one by one with reference to the left end portion of the sheet bundle and sees the image on the fourth page, it becomes difficult to see the other images up to the direction and upside down. Can be prevented.
[0250]
Further, for example, when the short edge binding setting is performed by the user on the setting screen of the printer driver, the driver matches the rotation designation of the small size page with the binding position of the large size page as a process of matching in the binding direction. Process to follow instructions.
[0251]
Hereinafter, a description will be given using the example shown in FIG.
[0252]
If the rotation designation data corresponding to each page is set without the driver performing alignment processing in the binding direction, the first page, the second page, the third page, and the fourth page are set as described above. The image rotation designation is set to 0 degrees, 0 degrees, 0 degrees, and 180 degrees, respectively, and the rotation designation for each page is output to the printer side as a driver instruction (see FIG. 13B).
[0253]
In this case, if the printer does not perform processing for aligning in the binding direction, the orientation of the second page image formed on the second surface of the recording paper A is other as shown in FIG. This is 180 degrees different from the orientation of the image formed on the surface.
[0254]
On the other hand, when the driver performs the process of aligning in the binding direction, the rotation designation of the image formed on the recording paper A that is an A4 size sheet is designated as the rotation of the image formed on the recording paper B that is an A3 size sheet. Fit to specification.
[0255]
For example, the rotation designation of the P2 image formed on the second surface of the recording paper A (that is, the rotation designation of the small size page) is designated, and the rotation designation of the image of the fourth page formed on the second surface of the recording paper B is designated. It is set so that the rotation designation is the same as (that is, the rotation designation of the large page). In this case, the rotation designation for the second page image is 180 degrees, which is the same as the rotation designation for the fourth page image.
[0256]
Therefore, when the driver performs the alignment process in the binding direction, the driver designates the rotation designation of the first page, second page, third page, and fourth page images by 0 degrees, 180 degrees, 0 degrees, 180 degrees is set, and the rotation designation for each page is output to the printer as a driver instruction.
[0257]
That is, as described above, when a plurality of sheets having different sizes are collected as one bundle as a process for aligning in the binding direction, the driver overlaps the short side of the large size sheet and the long side of the small size sheet. Thus, rotation designation data that is expected to be aligned in each sheet is set for each image data.
[0258]
In this case, on the printer side, the rotation of the image is performed according to the driver's instruction, and the image is formed so that the orientation of the second page image formed on the second surface of the recording paper A is the other surface. Therefore, even when a plurality of paper sizes are mixed in the same document, it is possible to output an optimal double-sided printing result aligned with the binding direction.
[0259]
As described above, by performing processing for matching in the binding direction on the driver side, it is not necessary to perform processing for alignment in the binding direction on the printer side, so that processing to be performed by the printer is reduced. I can do it.
[0260]
Accordingly, the processing efficiency can be improved and the load on the apparatus can be reduced.
[0261]
Further, in the PC / WS 7A, even if any mode (long-side binding double-side mode or short-side binding double-side mode) is set by the user for a document in which a plurality of paper sizes are mixed, the printer side or the driver side In the case where a plurality of sheets having different sizes are combined as one bundle as processing for aligning in the binding direction, the orientation of each sheet is set so that the short side of the large size sheet and the long side of the small size sheet overlap each other. The rotation designation data that is expected to be aligned may be automatically set for each image data, and a message to that effect may be displayed on the setting screen of the PC / WS 7A.
[0262]
Further, when there are a plurality of buttons for setting the binding as in the printer driver setting screen shown in FIG. 9C, only one button for setting the binding is selected. It may be possible to configure the display so that the other buttons cannot be selected and are displayed lightly or shaded so that they cannot be selected.
[0263]
Thereby, while reducing the operation which a user should perform, the misoperation by a user can be prevented.
[0264]
