[Mathematical formula-see original document] n '= N% L The number of layouts L is compared, and if there are two layouts, the process proceeds to step S801 (step S705). If there are four layouts, the process proceeds to step S901 (step S706).

9 and 10 are flow charts showing the copying process in the case of two layouts. First, the horizontal and vertical lengths Ox and Oy of the original are compared to determine whether the original is horizontal or vertical (step S802). First, a case is shown in which the horizontal feed auto paper is selected for a landscape portrait document.

It is determined whether or not the auto paper is selected (step S803). When the auto paper is selected, the horizontally fed paper is selected for a horizontally long document, and the portrait paper is selected for a vertically long document. Select the paper for feeding. Note that the automatic paper selection command may be replaced with vertical feed paper for a horizontally long document and horizontal feed paper for a vertically long document. If a sheet is selected on the operation unit 26, it is followed.

It is determined whether the original selected in FIG. 6D is horizontal writing or vertical writing (step S804). It is not always necessary to select the type of document shown in FIG. 6D, and there is no problem if the document is always selected for horizontal writing or vertical writing. Further, it is preferable for the user who does not use the vertically or horizontally written original document from the viewpoint of simplifying the operation procedure.

The counters in the X and Y directions of the image data are respectively incremented or decremented according to the document arrangement position n'calculated in step S704A (step S805).
When n '= 1 (step S806), the writing start position (Sx, Sy) is written from the position determined by setting the upper right corner of the paper as (0, 0) (step S80).
7). As a result, the image data is processed so that the image is formed at the positions and directions of “A” and “U” indicated by the arrows a and b in FIG. 15, respectively. FIG. 15 is an explanatory diagram showing the position and orientation of the image formed. "A",
"A", "U", and "D" represent (4N-3) page, (4N-2) page, (4N-1) page, and 4N page, respectively (N is a natural number).

On the other hand, if n '= 0 (step S80)
In 8), the image data is processed so that the image is formed in the positions and directions of "a" and "d" indicated by arrows c and d in FIG. 15, respectively. In FIGS. 9 and 10, PL is the longer length of the paper. When this routine ends, the process returns to step S707.

If horizontal writing is performed in step S804, similar processing is performed (steps S805A and S80).
6A), and n ′ = 1 (step S807A), the image data is processed so that the image is formed at the positions and directions of “A” and “U” indicated by the arrows e and f in FIG. It In the case of n ′ = 0 (step S808A), FIG.
The image data is processed so that the image is formed at the positions and directions of "a" and "d" indicated by arrows g and h.

On the other hand, when the sheet is not the automatic sheet in step S803, the sheet is processed according to the feeding direction set by the operation unit 26 (step S809). When the vertical feed is designated by the operation unit 26, the same processing is performed (step S8).
04A to S806B) and when n '= 1 in vertical writing (step S807B), an image is formed at the positions and orientations of "A" and "U" indicated by arrows i and j in FIG. Image data is processed. When n '= 0 (step S808B), the image data is processed so that the image is formed at the positions and directions of "a" and "d" indicated by arrows k and l in FIG.

When n '= 1 in horizontal writing (step S807C), the image is formed so that the image is formed at the positions and directions of "A" and "U" indicated by the arrows m and n in FIG. The data is processed. If n '= 0 (step S808C), the image data is processed so that the image is formed at the positions and directions of "a" and "d" indicated by arrows o and p in FIG.

The same processing is performed when it is determined in step S802 that the original is a portrait document. That is, when a vertically long document is vertically written and vertically fed and n '= 1 (step S807D), the image is displayed at the positions and orientations of "A" and "U" indicated by arrows q and r in FIG. The image data is processed so that When n '= 0 (step S808D), the image data is processed so that the image is formed at the positions and directions of "a" and "d" indicated by arrows s and t in FIG.

When the document is a horizontal document and n '= 1 (step S807E), an image is formed at the positions and directions of "A" and "U" indicated by arrows u and v in FIG. Image data is processed. When n ′ = 0 (step S808E), the image data is processed so that the image is formed at the positions and directions of “a” and “d” indicated by arrows w and x in FIG.

On the other hand, when the sheet is not the automatic sheet in step S803A, the sheet is processed according to the feeding direction set by the operation unit 26 (step S809). When the vertical feed is designated by the operation unit 26, the same processing is performed (step S
804C to S806F), and in the case of vertical writing and n ′ = 1 (step S807F), an image is formed at the positions and orientations of “A” and “U” indicated by arrows y and z in FIG. Image data is processed. When n '= 0 (step S808F), the image data is processed so that the image is formed at the positions and directions of "a" and "d" indicated by the arrows a1 and b1 in FIG.

If n '= 1 in horizontal writing (step S807G), the image is formed so that the image is formed at the positions and directions of "a" and "d" indicated by arrows c1 and d1 in FIG. The data is processed. When n ′ = 0 (step S808G), the image data is processed so that the image is formed at the positions and directions of “A” and “U” shown by the arrows e1 and f1 in FIG.

As a result of such processing, when the paper is fed laterally in the 2-in-1 mode and the double-sided mode, that is, when the long side of the paper is to be bound, "U" is displayed on the back of "A" and "I" is printed. When performing double-sided copying so that "d" is on the back of "" and feeding the paper vertically, that is, when trying to bind the short side of the paper, "d" is printed on the back of "a",
Perform double-sided copying with "U" on the back of "A". The lateral feed, the vertical feed, and the long-side binding and short-side binding of the sheets are related to the physical restrictions of the staple sorter 82.
This is because the staple sortable area of the staple sorter 82 is limited to the vicinity of the discharge portion of the sorter.

In the above-mentioned configuration, the arrangement of each original is changed depending on whether the side to be bound at two places is the long side or the short side of the paper. However, the binding margin setting content input by the operator from the operation unit is long. If the binding margin is set along the side,
If the setting is such that double-sided copying is performed with "U" on the back of "A" and "E" on the back of "A" and a binding margin is provided along the short side, the back of "A" The double-sided copying may be performed so that "d" is placed in the background and "u" is placed behind the "a".

Although copying has been described in the above configuration, it is clear that the same effect can be obtained when 2-in-1 double-sided printing of an image created by a computer or the like is performed.

As described above, when 2-in-1 double-sided recording is performed in both long-side binding and short-side binding, it is possible to create a book with no unnatural page relation when turning over.

11 to 14 are flow charts showing the copying process in the case of four layouts. Similar to the case of the two layouts, first, the horizontal orientation and the vertical orientation of the original are determined (step S902). It is determined whether or not the auto paper is selected (step S903). When the auto paper is selected, the horizontal feed paper is selected for a landscape original and the vertical feed paper is selected for a portrait original. Note that, as in the case of the 2 layout, the automatic paper selection command may be replaced with vertical feed for a horizontally long document and horizontal feed for a vertically long document. If a sheet is selected on the operation unit 26, it is followed.

Then, as in the case of the two layouts, it is determined whether the original is horizontal writing or vertical writing (step S904). The counters in the XY directions of image data are respectively incremented or decremented from the document arrangement position n ′ calculated in step S704a (step S905), and the writing start position (Sx, Sy) is set to the upper right corner of the paper (0,
Write from the position determined as 0). 11 to 14, PS is the shorter length of the paper in the vertical and horizontal directions.

In the case of a landscape-oriented vertically-written original with horizontal feed, n '=

The image data is processed so that an image is formed at the positions and orientations of "d" and "h" indicated by. After the end of this routine, the process returns to step S707 (steps S906A to S912A).

If the sheet is not auto paper in step S903, it is processed according to the feed direction set by the operation unit 26 (step S913). When the vertical feed is designated by the operation unit 26, the same processing is performed (step S904A).
Up to S905B), when n ′ = 1 in vertical writing, the position and direction of “A” and “O” shown by arrows q and r in FIG. 16 are set, and when n ′ = 2, arrows s and t are set. Indicated "a",

912G).

Although the table of FIG. 16 is used to determine the orientation and arrangement of the images, the images are formed and combined even if the programs are programmed as shown in FIGS. 17, 18 and 19. When a user reads a sheet of paper, it can be read smoothly like a normal book as in FIG. Further, it is desirable to have a plurality of these tables so that the user can select them from the viewpoint of meeting a wide range of needs. On the contrary, in both the 2nd layout and the 4th layout, a model intended for a user who does not use a vertical writing original does not necessarily have to have the orientation and arrangement of the image in the vertical writing mode.

When the above processing is completed, the process returns to the main routine. In step S707, the automatic document feeder 1
The originals stacked on the original are fed one by one onto the surface of the original glass 2. The image of the original is read according to the contents specified by the operation unit 26, the scaling ratio set in the above-described processing, the writing start address of the image memory 25, and the like (step S708), and is stored in the image memory 25.

The value 1 is subtracted from each of the document arrangement positions n'and n and the number of documents N (step S709). It is determined whether or not the document arrangement position n ′ is n ′ = 0 (step S710). If the value is not 0, the process returns to step S705 and the same processing is repeated.

If n '= 0, the image data stored in the image memory 25 is printed in steps S713A and S714. At the time of printing, the image stored in the image memory 25 is read according to the orientation of the output paper or the like as shown in FIGS. Transfer and fix on top.

At this time, if it is determined that Z = 2 in step S711, and if it is determined that n = 0 is not satisfied in step S712, the back side printing is performed on the sheet in step S713B. The reverse side flapper 83
It is reversed and stacked on the intermediate tray 84. If it is determined in step S711 that Z = 2 is not true, the sheet is discharged after being printed on one side.

It is determined whether or not the number of prints designated by the operation unit 26 has ended (step S715). If not, the process returns to step S711 and step S7.
13 or the print operation of step S714 is repeated.

When the number of prints is completed, it is determined in step S716 whether or not the number N of originals is N = 0. If N = 0, the process returns to step S704 to repeat the same processing. .

After that, when the staple sort is selected in FIG. 4, the stapler 82a in FIG.
The stapling is performed at two places indicated by 2b. FIG. 20 is a plan view showing the image forming apparatus.

As a result of such processing, "a", "a",
When trying to bind the long side of the paper in 4-in-1 mode and double-sided mode in which "U" and "E" are placed in the upper left, upper right, lower left, and lower right (when the paper is fed horizontally)
And the orientation of the original is portrait, "ka" is on the back of "a", "o" is on the back of "a", and "ku" is on the back of "u". Perform double-sided copying so that "ki" is on the back of "e". Also, when the short side of a sheet is to be bound (when the sheet is fed in the vertical direction) and the direction of the document is horizontally long, double-sided copying with the same arrangement relationship is performed.

When the long side of a sheet is to be bound (when the sheet is fed in the horizontal direction) and the original is oriented in the horizontal direction, "ki" and "a" are printed on the back of "a". "Ku" on the back
However, double-sided copying is performed so that "o" is on the back of "u" and "ka" is on the back of "e". Further, when the short side of a sheet is to be bound (when the sheet is fed in the vertical direction) and the orientation of the original is portrait, copying is performed with the same layout relationship.

In the 4-in-1 mode and the double-sided mode in which "A", "A", "U", and "E" are arranged at the upper left, upper right, lower left, and lower right, respectively, when binding the long side of the paper (paper If the document is in the portrait orientation and the orientation of the original is portrait, then “ki” is printed on the back of “a”, “ku” is printed on the back of “a”, and “ki” is printed on the back of “u”. Duplex copying is performed so that "O" and "E" are behind "E". Also, when the short side of a sheet is to be bound (when the sheet is fed in the vertical direction) and the direction of the document is horizontally long, double-sided copying with the same arrangement relationship is performed.

If the long side of the sheet is to be bound (the sheet is fed laterally) and the direction of the document is landscape, then "a" is followed by "ka" and "a". Both sides are copied so that "O" is on the back of "", "K" is on the back of "U", and "Ki" is on the back of "E". Further, when the short side of a sheet is to be bound (when the sheet is fed in the vertical direction) and the orientation of the original is portrait, copying is performed with the same layout relationship.

Further, of the above, the case where the direction of the document is portrait is also called portrait and the case where the document is landscape is called landscape. This portrait / landscape information may be determined according to the document setting direction or may be input by the operator from the operation unit.

Further, in the above-mentioned configuration, copying has been described, but it is clear that the same effect can be obtained when 4in1 double-sided printing of an image created by a computer or the like is performed.

As described above, in any of long-edge binding, short-edge binding, portrait, and landscape, when 4in1 double-sided recording is performed, it is possible to create a book having no unnatural page relation when turning over.

As described above, according to the image forming apparatus of the present embodiment, the orientation and arrangement of the original image are 2 in 1.
By performing double-sided copy or 4-in-1 double-sided copy and stapling at two places, when the user reads these sheets, the original content can be read smoothly and comfortably as if it were a normal book regardless of whether it is written vertically or horizontally. it can.
