Description

  The present invention relates to an image forming apparatus having a print preview display function and a print preview image display program for causing a computer to execute print preview processing.

An image forming apparatus such as a copying machine or a facsimile machine is based on printing data (image data, print job data, etc.) related to an image for one page or a plurality of pages (hereinafter referred to as a page image) read from an original. Some have a print preview function for displaying an image image (preview image) when a page image is output on a recording sheet (image formation) on a display unit such as a liquid crystal panel. This print preview function is an important function for preventing wasteful image formation against the user's will and suppressing wasteful consumption of recording paper and developer.
For example, Patent Document 1 discloses that when a print result when bookbinding is scheduled and duplex printing is performed is displayed as a preview, each page image is displayed side by side on a display unit.
Patent Document 2 discloses that a part of page images (reduced images) for a plurality of pages are displayed side by side on a display unit in a superimposed state.
JP 2004-164105 A JP-A-4-373073

By the way, it is important that the printing result of double-sided printing can confirm both the page order and the front / back relation of each page image by a preview image before printing (image formation). In particular, if you plan to bind (bind) a plurality of recording sheets obtained by double-sided printing, both the page order of each page image and the front / back relationship, and the state of the actually bound recording sheet It is desirable that it can be intuitively confirmed by a preview image.
However, when previewing the printing result of double-sided printing, as shown in Patent Document 1 and Patent Document 2, simply displaying a preview image in a state in which the printed page images are arranged, the page order and front / back relationship of each page image are displayed. Both are difficult to grasp intuitively.
Therefore, the present applicant displays a preview image in which a part of the uppermost original of the stacked originals is turned over, and is exposed by being turned over from the image on the back side of the uppermost original. A back side document of the uppermost document on each of the portion and an image of the front surface of the document next to the uppermost document and exposed by turning the uppermost document as described above Has filed a patent application (Japanese Patent Application No. 2007-013789) for displaying an image obtained by reducing the first image and an image obtained by reducing the surface image of the second document.
In this new preview method, it is possible to actually see the back side and part of the image on the next side while imagining the state where the originals to be printed on both sides are overlaid. The back side and the second original can be confirmed as if turning the original, and a preview display according to the user's feeling is possible.

  However, in the above-described new preview method, the repeated eye image displayed in the flipped part is always formed only on one end of the recording paper. However, N original images are formed on one recording material. When Nin1 printing is set for printing, or when the page image is an Nin1 format image in which N original images are printed on one recording material, another original page image recorded on the recording paper Is not turned over. For example, with 2in1 print settings or printed materials, it is not always possible to flip an odd-numbered page image, so you can check the back side or the second page as if you were turning the document, or display a preview according to the user's feeling. There was an inconvenience that these odd pages were not possible.

  Accordingly, the present invention has been made in view of the above circumstances, and the object of the present invention is to enable repeated display for all pages even in the case of Nin1 print settings or image formation from printed matter. Thus, an image forming apparatus and a print preview image display program capable of a preview display process that is easy for humans to see are provided.

In order to achieve the above object, an image forming apparatus according to the present invention displays a print preview image of a page image based on double-sided printing data relating to page images for a plurality of pages stored in a predetermined storage unit. The image forming apparatus to be displayed on the recording material is formed on the front surface of the recording material when duplex printing based on the printing data is performed based on information input through a predetermined operation unit. The page specifying means for specifying the page of the page image and the front surface of the recording material in a state in which a part of the recording material on the top surface is turned over from a state where a plurality of recording materials are stacked. The first region corresponding to the surface portion, the second region corresponding to the back surface portion of the uppermost recording material, and the third region corresponding to the front surface portion of the second recording material, Before the first area An image of a part of the page specified by the page specifying means that has not been turned over is displayed, and each of the second area and the third area includes the page specified by the page specifying means. Nin1 for printing N original images on a single recording material in an image forming apparatus comprising a repeated image display means for performing a repeated image display process for displaying respective images for the next two pages. In the image forming apparatus, the turned-up image display means displays the turned-up image for each of the original images in the one recording material at the time of print setting.
When the page image is a Nin1 format image in which N document images are printed on one recording material, the page image is for double-sided printing related to a plurality of page images stored in a predetermined storage means. An image forming apparatus for displaying a print preview image of the page image on a display unit based on data, wherein duplex printing based on the print data is performed based on information input through a predetermined operation unit In this case, a page specifying means for specifying the page image page formed on the front surface of the recording material and a part of the recording material on the uppermost surface from a state where a plurality of recording materials are stacked are turned over. The first region corresponding to the front surface portion of the uppermost recording material, the second region corresponding to the rear surface portion of the uppermost recording material, and the second recording material Phase on the front side For the third area to be displayed, an image of a portion of the page image of the page specified by the page specifying means that is not turned over is displayed in the first area, and the second area and the third area are displayed. In each of the image forming apparatuses, each region includes a repeated image display unit for performing a repeated image display process for displaying each image for the next two pages of the page specified by the page specifying unit. When the page image is an Nin1 format image in which N document images are printed on one recording material, the flipped image display means is configured to display each document image in the one page image. It can also be grasped as an image forming apparatus characterized in that the repeated image display is performed every time.
In this case, it further comprises page dividing means for dividing an Nin1 format image in which N original images are printed on one recording material into page images for each original image, and the repeated image display means It is also possible to display the flipped image for each page image divided by the page dividing means.

  According to the present invention, there is provided an image forming apparatus that displays a print preview image of a page image on a display unit based on double-sided printing data relating to page images for a plurality of pages stored in a predetermined storage unit. A page specifying means for specifying a page of the one page image formed on the front surface of the recording material when double-sided printing based on the printing data is performed based on information input through the operation unit A first area corresponding to a front surface portion of the uppermost recording material in a state where a part of the uppermost recording material is turned over from a state in which a plurality of recording materials are stacked, With respect to the second area corresponding to the back surface portion of the uppermost recording material and the third area corresponding to the front surface portion of the second recording material, the page specifying means includes the first area. Identified page An image of a portion of the page image that has not been turned over is displayed, and each of the second area and the third area is an image corresponding to the next two pages of the page specified by the page specifying means. In a repetitive image display means for performing a repetitive image display process for displaying a repetitive image, the repetitive image display is performed when Nin1 printing is set to print N original images on a single recording material. In the case of an image forming apparatus in which the means displays the repetitive image display for each original image in the one recording material, when the print setting of Nin1 is set, 1 Since the flipped image display is performed for each original image on a sheet of recording material, the page to be printed can be visually grasped for any page image, and the operator can perform printing. Image forming apparatus capable of Nozomu pages accurately known in advance whether the printing is provided.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that the present invention can be understood. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.

It is a figure which shows a screen.

An image forming apparatus X according to an embodiment of the present invention is an image forming apparatus such as a copying machine, a printer, or a facsimile machine, and prints a plurality of pages of page images stored in advance in a data storage unit such as a hard disk. A print preview function for displaying a print preview image of the page image on the display unit based on the data for use is provided.
First, the structure of the main part of the image forming apparatus X according to the embodiment of the present invention will be described with reference to the block diagram shown in FIG.
The image forming apparatus X is a so-called multifunction machine having a scanner function, a print function, a copy function, and a facsimile function.
As shown in FIG. 1, the image forming apparatus X includes a main control unit 1, an operation / display unit 2, a data storage unit 3, an image processing calculation unit 4, a NIC 5, a scanner unit 6, a printing unit 7, a facsimile unit 8, and the like. They are connected in such a way that information can be exchanged through the bus 11.
The operation / display unit 2 includes an operation unit 2a for inputting information and a display unit 2b for displaying information (including images). The operation unit 2a is, for example, a touch panel or a sheet key provided on the surface of the liquid crystal display device. The display unit 2b is, for example, a liquid crystal display device. The operation / display unit 2 constitutes a man-machine interface for the user.
The data storage unit 3 is a readable / writable large-capacity non-volatile memory that stores processing data as necessary when processing image data obtained by reading from a document or printing processing of image data. .
The image processing arithmetic unit 4 is constituted by a dedicated signal processing circuit or a DSP (Digital Signal Processor) or the like, performs various image processing on the image data, and forms a print job described in a predetermined print job description language into an image. A process for converting to bitmap image data to be used, a process for generating image data to be transmitted to an external device (for example, image data subjected to predetermined encoding such as JPEG format), and the like are performed.

The NIC 5 receives data (including data of an image read by the scanner unit 6) with an external device such as an information processing terminal or an e-mail server through a network including a LAN and the Internet conforming to the standard IEEE 802.3, for example. It is a communication interface which transmits / receives.
The scanner unit 6 converts an image formed on a document from a document placed on a glass document table (not shown) or a document conveyed by an ADF (not shown) to a color (R, G, B). ) Is a color scanner that distinguishes and reads.
The print unit 7 is a so-called print engine controlled by the main control unit 1, and sequentially feeds recording sheets stored in a sheet feeding cassette (not shown) one by one, and passes through a predetermined image forming position to a sheet discharge tray. Recording paper (recording paper) based on the image data of the original read from the original by the scanner unit 6 and the image data for printing generated by the image processing calculation unit 4 at the image forming position. It is a set of components such as a device that forms (outputs) an image on an example) and an MPU that controls the device. The printing unit 7 has a function of executing double-sided printing processing for forming an image on both the front surface and the back surface of the recording paper.
The facsimile unit 8 includes communication means such as an NCU (Network Control Unit) and a modem, and performs dial-up and negotiation processing for determining a communication method with a communication partner (partner station). It transmits and receives facsimile data (image data read by the scanner unit 6) with the facsimile apparatus.

The main control unit 1 controls each of the scanner unit 6, the print unit 7, the facsimile unit 8, the operation / display unit 2, the data storage unit 3, and the image processing calculation unit 4.
For example, the main control unit 1 causes the printing unit 7 to execute a printing process (image forming process) based on a print job received through the NIC 5. Further, the main control unit 1 causes the facsimile unit 8 to execute a facsimile transmission process for calling a designated transmission destination telephone number and transmitting image data to be transmitted. Further, the main control unit 1 causes the scanner unit 6 to execute a scanning process for reading an image formed on the original from the original.
Further, the main control unit 1 is based on printing data (image data, print job data, etc.) relating to an image for one page or a plurality of pages (hereinafter referred to as page image) read from the document by the scanner unit 6. Print preview processing is also executed for causing the display unit 2b to display an image image (preview image) when the page image is output (image formation) to the recording paper.

Next, the procedure of the print preview process executed by the image processing apparatus X will be described with reference to the flowchart shown in FIG. 2 and the print preview screen examples shown in FIGS.
It is assumed that printing data is stored in advance in the data storage unit 3 before the processing shown in FIG. As described above, the print data is a print job input from the external device through the NIC 5 or image data read by the scanner unit 6. S1, S2,... Shown below represent identification symbols of processing procedures (steps).

[Steps S1 to S4]
First, the main control unit 1 displays a predetermined initial menu screen on the display unit 2b (S1), and monitors whether or not an operation for selecting a processing item in the initial menu has been performed through the operation unit 2a (S2). ).
When the main control unit 1 detects that an operation for selecting any processing item is performed during the display of the initial menu, the main control unit 1 executes a process corresponding to the operation.
That is, when the operation for the initial menu is an operation for requesting print preview display processing (print preview operation), the main control unit 1 sets an initial value (= 1) for a variable i representing a page number. Above (S3), it is determined whether or not the printing data stored as a processing target in the data storage unit 3 is data for double-sided printing that has been selected in advance as a target for double-sided printing (S4). .
The double-sided printing data is print job data or read image data relating to page images for a plurality of pages.
Note that the variable i is a variable that represents a page of one page image formed on the front surface of the recording paper when double-sided printing is performed based on the double-sided printing mode of the normal mode described later. . In this case, the value of the variable i is an odd value of 1 or more.
The variable i is a variable representing the page of one page image formed on the left side of the front surface of the recording paper when double-sided printing is performed based on the 2-in-1 mode double-sided printing mode described later. . Also in this case, the value of the variable i is an odd value of 2 or more. However, the definition of the variable i is based only on the appearance. For example, even in the 2-in-1 printing mode, if the variable i is considered to be a variable representing the page of one page image formed on the left side of the front surface of the recording paper. , Variable i is an even value of 2 or more.
In addition, the main controller 1 that executes the process of step S3 specifies the value of the variable i based on information (information requesting print preview display) input through the operation unit 2a. It is an example.

[Steps S5 and S6]
When the main control unit 1 determines in step S4 that the printing data is double-sided printing data, the main control unit 1 selects pages (i-1) to (i + 2) based on the double-sided printing data. Four pages of page image data are generated (S5). In step S5, it is needless to say that image data relating to pages not included in the double-sided printing data among the page images for four pages from the (i-1) page to the (i + 2) page is not generated. .
Next, the main control unit 1 determines whether the display mode of the print preview at that time is the “normal mode” or the “2 in 1 mode” (S6). The display mode is information for identifying what type of print preview image is to be displayed on the display unit 2b in the print preview image display process based on the double-sided printing data. The contents of will be described later. The initial state of the display mode is “normal mode”, and thereafter, the display mode is switched to either “normal mode” or “2 in 1 mode” according to an input operation through the operation unit 2b. The 2in1 mode is an example of the Nin1 mode (N = 2, an even value of 9 or more), and the same processing is performed even when N = 4 or more, but is omitted here.

[Step S7]
When the display mode is “normal mode”, the main control unit 1 determines “4” page image data from page (i−1) to page (i + 2) generated in step S5. Data of a print preview image for “normal mode” is generated, and the print preview image is displayed on the display unit 2b.
3 and 4 are examples of display screens of print preview images for the “normal mode”. FIG. 3 shows an example in which there is no page image of (i−1) page because page variable i = 1, and FIG. 4 shows that page variable i = 3 and (i−1) from page (i + 2). ) This is an example in the case where there are four page images up to (2 to 5 pages).

As shown in FIG. 3 and FIG. 4, the print preview image displayed on the display unit 2b by the main control unit 1 is the state of the uppermost (i-th page) recording sheet from a state in which a plurality of recording sheets are stacked. It includes an image (hereinafter referred to as a flipped image g1) representing a state in which a part (for example, the lower right portion) is turned over. Accordingly, the flipped image g1 includes the first area p1 corresponding to the front surface (i-th page) portion of the uppermost recording paper, and the back surface (i + 1-th page) portion of the uppermost recording material. And a third region p3 corresponding to the front surface (i + 2 page) portion of the second recording material.
In the “normal mode”, the main control unit 1 sets each of the first to third regions p1 to p3 in the flipped image g1 by the process of step S3 described above or step S9 described later ( A part g12, g22, and g32 of each of the page images for three pages from the specified i page are displayed.

More specifically, regardless of the display mode, the main control unit 1 causes the first area p1 in the turned-up image g1 to be in the first area by the duplex printing process based on the duplex printing data. An image g12 (part of the page image) formed in the portion corresponding to the region p1, that is, the remaining non-turned portion of the page image of the i-th page except the portion hidden by turning the recording paper. Display as it is.
Further, in the normal mode, the main control unit 1 performs the second printing by double-sided printing based on the double-sided printing data in each of the second region p2 and the third region p3 in the flipped image g1. Part g22 and g32 of the page image formed in portions corresponding to the region p2 and the third region p3 are displayed as they are. Thus, in the example shown in FIG. 4, the image g22 at the lower left corner of the page image of the (i + 1) th page is in the second area p2, and the (i + 2) th page is in the third area p3. Images g32 in the lower right corner of the page image are displayed.
Further, the main control unit 1 also displays page number information g11, g21, g31 corresponding to each region in each of the first to third regions p1 to p3.
Further, when the page number i exceeds 1, the main control unit 1, as shown in FIG. 4, the page image g0 of the (i-1) page immediately before the i page and the turnover image g1 Are displayed on the display unit 2b (S7).
In addition to the print preview image, the main control unit 1 also has a display target page change operation button g4, a display mode change operation button g5, and an end button g6, which are also used as the operation unit 2a. Display on the display unit 2b (S7).

[Steps S8, S9]
On the other hand, when the main control unit 1 determines that the display mode is the “2 in 1 mode” (that is, the user presses the display mode changing operation button g5 in S6, the print mode is set to 2 in 1). When it is determined that the mode has been switched), a preview screen in the 2-in-1 print mode shown in FIG. 5A is first displayed. Such a preview screen in the 2-in-1 print mode is well known and will not be described in detail. In short, if it is the first page, page images p1 and p2 on the first and second pages as shown in FIG. Are displayed side by side. At this time, it is also preferable to display the indications mr and ml indicating that the current turning display is possible at the corners of the left and right pages.
Further, turn buttons nr and nl indicated by arrows or the like for instructing turn-over can be provided. When the right turn button nr is pressed, the right page is turned at the display mr portion, and when the left turn button nl is pressed, the left page is turned at the display ml portion. .
FIG. 5 (b) shows a case where only the flip button nr is pressed, and FIG. 5 (c) shows a state in which part of the left and right pages are turned because both the flip buttons nr and nl are pressed. .
For example, when both the turn-over buttons nr and nl are pressed as shown in (c), the main control unit 1 determines the i-th page based on the number of pages i set (specified) by the process of step S3 described above. From the page image from the image to the (i + 5) th page, an image (P3, P4, p5, p6 in FIG. 6C) and an image that is inserted into each of the areas that are not repeated ( p1, p2) are created in the image storage unit (S8).
Then, the main control unit 1 prints print previews of p1 to p6 based on page image data for six pages from page i generated in step S5 to page i + 5 (1 to 6 in the case of FIG. 5). Image data is generated, and the print preview image is displayed on the display unit 2b (S9).
That is, in this embodiment, since the 2 in 1 mode is selected, the image pi (in this case, p1) and the i + 2 page are turned in the left half of the currently displayed print page. The returned image p3 of the returned image p3, i + 4 page is turned over, and the image p2, i + 3 page of the portion of the i + 1 page that has not been turned over is turned over in the right half. The images p6 that have been turned over on pages p4 and i + 5 are inserted and displayed.
In this way, even if the print setting is, for example, 2 in 1, all the page images to be printed can be visually confirmed by turning over, so that the desired page without any mistake can be very easily obtained. It is possible to perform printing processing after confirming that it is included.

[Steps S10 to S11]
Then, after the process of step S7 or S9 is completed, the main control unit 1 monitors whether any of the operation buttons g4 to g6 has been operated through the operation unit 2a (S10), and according to the operation content. For example, print processing.
That is, when the operation button g4 for changing the display target page (page change operation) is performed, the main control unit 1 changes the value of the variable i (page number) according to the operation (S12), and newly For the set page i, the processes in steps S5 to S9 described above are executed.
For example, when the main control unit 1 detects the operation of the previous page button or the next page button among the change operation buttons g4 for the display target page in step S10, the main control unit 1 subtracts the value of the variable i (−2) Add (+2). Further, when detecting the operation of the first page button or the last page button, the main control unit 1 sets the value of the variable to 1 or the value of the last odd page in the duplex printing data. In addition, when a page is directly designated by the operation of a numerical key (not shown), the main control unit 1 designates the value of the designated page if the designated page is an odd number, and designates the specified page even if the designated page is an even number. A value obtained by adding 1 to the page is set as a variable i.
In this way, the main control unit 1 sets the front side of the recording paper when double-sided printing based on the double-sided printing data is performed based on the information input through the operation unit 2b in step S10. A page of one page image formed on the surface is set (specified) (an example of the page specifying unit).

Further, the main control unit 1 changes the display mode when the operation of the display mode change operation button g5 (mode change operation) is performed (S11), and in the new display mode, the main control unit 1 changes the display mode. Steps S5 to S9 are executed.
As described above, the main control unit 1 applies the double-sided printing data to each of the second region p2 and the third region p3 in the flipped image g1 in accordance with an input operation through the operation unit 2b. A state in which part of the page images g22 and g32 formed in portions corresponding to the second region p2 and the third region p3 by double-sided printing based on the above are displayed as they are (state of FIG. 4), and a step In the process of S8, the state (state shown in FIG. 5) of switching the entire g23, g33 of each page image set to print Nin1 is switched.
This makes it easier to visually grasp the contents of the superimposed double-side printed page images.
In addition, when the end button g6 is operated (end operation), the main control unit 1 returns the processing to step S1 described above.
On the other hand, when the main control unit 1 detects an operation other than the print preview operation during the display of the initial menu in step S2, the main control unit 1 executes other processing according to the operation content (S20). , The process returns to step S1 described above.
Further, in step S4, the main control unit 1 is the single-sided printing data in which the printing data stored as the processing target in the data storage unit 3 is selected in advance as a single-sided printing target (see above). If it is determined that the data is not double-sided printing data, print preview processing of the single-sided printing data is executed (S21), and then the process returns to step S1 described above. Note that the processing in step S21 is not particularly related to the processing according to the present invention, and thus the description thereof is omitted here.

The image forming apparatus X described above displays, for example, a print preview image including the flipped image g1 as shown in FIG. 3 or FIG. 4 on the display unit 2b. It is easy to intuitively grasp both the page order and the front / back relationship of the recording paper.
Further, in response to an input of an operation button (not shown) for selecting whether or not the main controller 1 displays the repetitive image g1, the repetitive image g1 as shown in FIGS. It is also conceivable to switch between the print preview image including the image and the print preview image not including the flipped image g1 as shown in FIG.

In the example shown in FIGS. 3 to 5, the flipped image g <b> 1 represents a state in which the lower right portion of the recording paper is turned over. It is also conceivable to display the turn-up image representing the state in which the upper right portion of the recording paper or the recording paper is turned over, in a print preview image.
Further, the present invention may be realized as a print preview program that causes a computer such as a personal computer to execute the process shown in FIG. 2 executed by the image forming apparatus X described above.
For example, before the computer transmits a print job to the printer, the computer executes the print preview program, so that the print preview image as shown in FIGS. 3 to 5 is displayed on the graphic display (display unit). It is conceivable to display.

  The embodiment described above relates to the case where the main control unit 1 handles a page image set in advance to print Nin1, but the page image is printed with N original images on one recording material. A case where the image is a Nin1 format image can be processed. In this case, the image is turned over by displaying the turned-up image for each document image in the one page image. As a concrete advantageous embodiment, for example, an image of Nin1 format in which N document images are printed on one recording material is divided by the main controller 1 into page images for each document image. And storing it in the data storage unit 3 (corresponding to the page dividing means of the present invention) and displaying the repeated image for each page image divided by the page division. You just have to do it.

  The present invention can be used for an image forming apparatus and a program for causing a computer to execute print preview display processing.
