  However, when reading the back cover of a book in a bookbinding state with a reader device, one of the left and right margins is cut, so when reading the front side and back side of the paper after the back cover is cut. The left and right margins are different. Also, the reversed double-sided DF and the one-pass double-sided DF differ in how the margin is created when reading the back side. For this reason, when the image is stored / transmitted, the left and right margin balance of each page realized in the bookbinding state is lost. If the read image is transmitted to another display device or an electronic book as it is, there is a problem that it is read unbalanced and unsightly.

  Therefore, in the present invention, in order to solve the above problems, a means for determining whether or not the document is cut, a reader device with a DF, a means for adjusting left and right margins, and a means for storing an image. In an image forming system having means for transmitting an image, an image read using a reader device with a DF is analyzed and determined as a cut document. If the original is double-sided, a plurality of documents can be selected depending on the type of DF. As a result of reading the page, if the margin width at both ends in the sub-scanning direction is different between the front side and the back side, convert the left and right margin width to an image corrected according to the type of DF, adjust the appearance, By sending it to the opponent machine, the received document can be read nicely as it is.

  When adjusting the margin amount, the entire original is read, and it is determined whether or not to adjust the margin amount separately for the front side and the back side.

  Further, for the document data whose margin amount is a certain value or more, control is performed so that the margin amount is not adjusted.

  In addition, when the image read using the reader device with DF is analyzed and determined to be a cut document, and the original is double-sided, a plurality of pages are read as a result of reading from the platen, and the sub-scan direction If the margin widths of both ends of the front and back sides are different, the left and right margin widths are converted into images that have been individually corrected for the front and back sides, and the appearance is adjusted before being sent to an e-book reader or counter device. The received document can be read nicely as it is.

  As described above, an image having means for discriminating whether or not it is a cut document, reader device with DF, means for adjusting left and right margins, means for accumulating images, and means for transmitting images In the forming system, the image read using the reader device with DF is analyzed and determined to be a cut document. If the original is double-sided, the result of reading a plurality of pages according to the type of DF If the margin widths at both ends of the front and back sides are different, convert the left and right margin widths to an image corrected for the type of DF, send it to an e-book reader or counter device after adjusting the appearance. The received document can be read nicely with the display device as it is, with the image information well-balanced by the electronic book or MFP receiving the document.

  When adjusting the margin amount, the entire original is read, and it is determined whether or not to adjust the margin amount separately for the front side and the back side.

  Further, for the document data whose margin amount is a certain value or more, control is performed so that the margin amount is not adjusted.

  In addition, when the image read using the reader device with DF is analyzed and determined to be a cut document, and the original is double-sided, a plurality of pages are read as a result of reading from the platen, and the sub-scan direction If the margin widths of both ends of the front and back sides are different, the left and right margin widths are converted into images that have been individually corrected for the front and back sides, and the appearance is adjusted before being sent to an e-book reader or counter device. The received document can be read with good quality on the display device as it is, with the image information well-balanced by the electronic book or MFP receiving the document.

  Next, the details of the digital multifunction peripheral described in FIG. 2 will be described with reference to FIG. This multi-function machine has functions of copy, printer, FAX, and transmission.

  In FIG. 3, the multifunction peripheral includes a scanner 301, a document feeder (DF) 302, a print recording print engine 313 having a four-color drum, a paper feed deck 314, and a finisher 315.

  First, a reading operation performed mainly by the scanner 301 will be described. When a document is set on the document table and read, the document is set on the document table 307 and the DF 302 is closed. Then, after the open / close sensor 330 detects that the document table 307 is closed, the reflective document size detection sensors 331 to 335 in the housing of the scanner 301 detect the set document size. Starting from this size detection, the original is irradiated with the light source 310, and the CCD 343 reads the image via the reflecting plate 311 and the lens 312, and then converted into a digital signal, and is converted into a laser recording signal by performing desired image processing. Is done. The converted recording signal is stored in a memory in the controller.

  When a document is set on the DF 302 and read, the document is placed face up on the tray of the document setting unit 303 of the DF 302. Then, the document presence / absence sensor 304 detects that the document has been set, and the document feed roller 305 and the transport belt 306 rotate in response to this, and the document is transported, and the document is placed at a predetermined position on the document table 307. Is set. Thereafter, the image is read in the same manner as reading on the document table 307 and stored in the memory in the controller.

  When the reading is completed, the conveyor belt 306 rotates again to send the document to the right side of the drawing, and is discharged to the document discharge tray 309 via the discharge roller 308. When there are a plurality of originals, the originals are discharged and conveyed from the original table 307 to the right side of the figure, and at the same time, the next original is fed from the left side via the paper supply roller 305, and the reading of the next original is continuously performed. Done. The above is the operation of the scanner.

  Next, a printing operation performed mainly by the printer 313 will be described. The recording signal (print image data) once stored in the memory in the controller is transferred to the printer 313 and converted into four colors of recording laser light of Yellow, Magenta, Cyan, and Black by the laser recording unit. Then, each color photoconductor 316 is irradiated to form an electrostatic latent image on the photoconductor. Then, toner development is performed with the toner supplied from the toner cartridge 317, and the visualized image is primarily transferred to the intermediate transfer belt 321. Thereafter, the intermediate transfer belt 321 rotates in the clockwise direction. When the recording paper fed from the paper cassette 318 or the paper feed deck 314 through the paper feed conveyance path 319 reaches the secondary transfer position 320, the intermediate transfer belt 321 is rotated. The image is transferred from the belt 321 to the recording paper.

  The recording paper onto which the image has been transferred is fixed with toner by pressurization and heat in the fixing device 322, and is conveyed through the paper discharge conveyance path, and then is switched back to the face-down center tray 323 or discharged to the finisher. The paper is discharged to the paper port 324 or the face-up side tray 325 (however, the side tray 325 is a paper discharge port that can discharge paper only when the finisher 315 is not mounted). The flappers 326 and 327 are for switching the transport path in order to switch these discharge ports. In the case of double-sided printing, after passing through the fixing device 322, the flapper 327 switches the conveyance path, and then the sheet is switched back and the recording sheet is fed downward. 320 is fed to realize a double-sided operation.

  Next, operations performed by the finisher 315 will be described. The finisher 315 performs post-processing on the printed paper according to the function designated by the user. Specifically, it has functions such as stapling (1 place / 2 places binding), punching (2 holes / 3 holes), and bookbinding saddle stitching. The multifunction peripheral of FIG. 3 has two paper discharge trays 328, and the recording paper that has passed through the paper discharge outlet 324 to the finisher 315 is discharged for each copy, printer, fax, and transmission function, for example, depending on user settings. Sort paper trays. The print engine 313 is a color 4-drum printer, but it is needless to say that a color 1-drum engine or a monochrome recording printer engine may be used. When used as a printer, various settings such as black and white / color print, paper size, 2UP / 4UP printing / N-UP printing, duplex, staple, punch, saddle stitching, slip sheet, front cover, back cover, etc. are set by the driver. Is possible.

  Next, functions and operations of the controller of the digital multi-function peripheral in the system configuration described above will be described below.

<Scanned image reading function>
The digital multi-function peripheral has a scan image reading function for printing or transmitting a read image from a document through a reader unit. In accordance with a user instruction input from the operation panel unit 208 through the panel I / F unit 209, the CPU 207 moves the reader device 218 through the scanner I / F unit 220 according to the program of the image data reading unit 230 described in the program ROM 222. Then, the scanned image of the original document is captured from the reader device 218 through the scanner I / F unit 220. The captured image is stored in the RAM 212 through the bitmap image receiving unit 221, the bitmap image is compressed by the image compression / decompression unit 227, and is stored in the RAM 212 as a compressed image.

<Image printing function>
This digital multi-function peripheral has an image printing function for printing a compressed image held on the RAM 212 by the scan image reading function. When printing of the image obtained by the scan image reading function is designated, the CPU 207 compresses / decompresses the compressed image stored in the RAM 212 in accordance with the program of the image data printing unit 228 described in the program ROM 222. It is possible to develop a bitmap image by the unit 227 and print it as it is, and to set various print settings such as a paper feed port, a paper discharge port, and a print mode through the engine I / F unit 216. In addition, the selected image is sent to the printing apparatus engine unit through the engine I / F unit 216 in the bitmap image transfer unit 217, printed, and discharged from the designated discharge port. Will be.

<Copy function>
In this digital multi-function peripheral, a copy function is realized by a function of printing the scanned image reading function and the image printing function continuously. When the user places a document to be copied on the reader apparatus, selects a copy key on the panel, and presses the start key to give a copy instruction, the CPU 207 executes a scan image reading function and an image print function, and scans The scanned image of the original is stored in the RAM 212 by the image reading function, and printing by the image printing function is executed, and the image read from the printer device is printed.

<Image transmission / reception function>
This digital multi-function peripheral has a function of transmitting an image held on the RAM 212 by the scan image reading function. When a user sets a document to be transmitted to the reader device, selects a transmission key on the panel, and presses a start key to give a transmission instruction, the CPU 207 executes a scanned image reading function, and the scanned image of the document is stored in the RAM 212. In addition to being stored, the image compression / decompression unit 227 converts the image into a bitmap image according to the program of the image data transmission unit 229 described in the program ROM 222 and stores it in the RAM 212. Thereafter, the image stored in the RAM 212 is attached to a transmission destination such as a mail address designated by the user and transmitted from the input / output unit 205 through the input / output buffer 206.

  This digital multi-function peripheral has a function of receiving images. The image data transmitted from the apparatus having another image transmission function to the digital multi-function peripheral is connected to the input / output unit via the communication line 203 from the network 201 in accordance with the program of the image data receiving unit 238 described in the program ROM 222. The data is received from the input / output buffer 206 from 205. The received image data is held on the RAM 212 or is printed by an image printing function, and an image is printed by the printer device.

  In this embodiment, the cut double-sided document is placed on the DF and read, and according to the type of the DF, the result of reading a plurality of pages is added to the document type to calculate the left and right margin width of each page, FIGS. 1 and 4 show a case in which image data is corrected by adjusting the left and right margin widths separately for the front side and the back side according to the document type and the DF type, and sent to an electronic book or a counter machine after adjusting the appearance. Will be described with reference to FIG.

  FIG. 1 is a diagram showing a sequence in which a cut document described in the present invention is sent to an electronic book or a counter machine after adjusting the margin width according to the DF type to adjust the appearance. FIG. 4 is a diagram showing a screen flow for setting a mode for transmitting a cut document. FIG. 5 is a diagram showing a sequence of margin width adjustment processing according to the type of cut document (left-open or right-open) and the type of DF. FIGS. 6 to 9 are diagrams showing the state of image processing in the actual image forming system for the four types of document types (left-open or right-open) and DF types shown in FIG. It is.

  First, using the operation panel unit 208 of the image forming system, a mode for reading and transmitting a cut document is set (step S101). The operation status at this time will be described with reference to FIG.

  When a “user mode” key (not shown) is pressed to display a setting screen (step S401), a user mode main screen is displayed (step S402).

  In this example, the user mode main screen includes "common specification setting", "timer setting", "adjustment / cleaning", "report specification setting", "system management setting", "copy specification setting", "send / There are “Receive specification setting”, “Box specification setting”, “Printer specification setting”, “Destination table specification setting”, and when “Send / Receive specification setting” is pressed from here, the Send / Receive specification setting screen is displayed ( Step S403).

  The transmission / reception specification setting screen includes “send document after cutting” in addition to “transmission specification setting” and “reception specification setting”. When the “send cut document” key is pressed on the transmission / reception specification setting screen, a setting screen for sending the cut document is displayed (step S404). On the setting screen for transmitting the document after cutting, it is possible to set whether the bookbinding document before cutting is a left-open book or a right-open book. When either the “left open” key or the “right open” key is pressed and then the “close” key is pressed, the cut document is set to be transmitted.

  Thereafter, a transmission destination such as an electronic book or a counter device for actually transmitting a document is specified, and a transmission mode such as a size of a document to be transmitted, a duplex mode, and a file format is specified (step S405).

  When the mode setting for reading and transmitting the document cut in step S101 is completed, the cut document is placed on the DF 302 (step S102).

  When the mode setting and document setting are completed, the document reading is started by pressing the start key (step S103), and the document on the DF 302 is sequentially read by the reader device 218. At this time, the type of the DF 302 is automatically determined inside the image forming system.

  The read image data is subjected to margin amount adjustment processing for each page according to the left / right opening method set in step S404 and the type of DF automatically determined in the image forming system (step S104). The sequence of margin width adjustment processing at this time will be described with reference to FIG.

  First, it is determined whether the document specified in step S404 is “left open” or “right open” (step S501). If “left open” is specified, the type of the DF 302 is subsequently determined (step S501). In S502), when the reverse double-sided DF is mounted, when reading a double-sided original, first the front side is read, and then the original is automatically turned over to read the back side. Here, the state of the image processing in the actual image forming system when “before cutting is a left-open book and when the reversed double-sided DF is used” will be described with reference to FIG. The state of the document before and after cutting is as 601. When this original is read by the reverse double-sided DF, as shown in 602, the left margin of the front side image becomes small.

  At this time, the difference between the length of the document drawn from the DF and the set document size is calculated when each page is read (step S503). Here, when the original is the back side, it is not necessary to correct the margin as shown in 602 of FIG. 6 described above, so it is necessary to determine whether the front side is read or the back side is read. Yes (step S504).

  When the front side of the document is read and the difference between the document length and the document size width is calculated, the image on the front side is shifted to the right by the calculated size width (step S505), and the page (front side) Are stored (step S506).

  If the difference between the document length and the document size is calculated by reading the back side of the document, margin correction is unnecessary, and the read image of the page is stored as it is (step S506).

  As a result, “the state stored as an image to be transmitted” when “the left-open book is before the cutting and the reversed double-sided DF is used” is a state in which the margin width is adjusted as represented by 603 in FIG.

  If the 1-pass double-sided DF is attached in step S502, the front side and the back side are read simultaneously when reading a double-sided original. Here, the state of image processing in the actual image forming system when “the pre-cutting is a left-open book and one-pass duplex DF is used” will be described with reference to FIG. The state of the document before and after cutting is as indicated by 701. When this original is read with a one-pass duplex DF, the left margin of the front side image is reduced and the right margin of the back side image is reduced, as represented by 702.

  At this time, the difference between the length of the original drawn from the DF and the set original size is calculated when the front side and the back side are simultaneously read (step S507). Here, as represented by 702 in FIG. 7 described above, the image shift direction differs between the front side and the back side of the document.

  That is, the front side image is shifted to the right by the calculated size width (step S508), the back side image is shifted to the left by the calculated size width (step S509), and the page (the front side The image of the back surface is saved (step S510).

  As a result, “the state stored as an image to be transmitted” in “when the left-open book is before the cutting and the one-pass duplex DF is used” is a state in which the margin width is adjusted as represented by 703 in FIG. 7.

  If “Right Open” is designated in step S501, the type of DF 302 is subsequently determined (step S511). If the reversed double-sided DF is mounted, when reading a double-sided document, the first Scan the side, then turn the document over automatically to scan the back side. Here, an actual image processing state in the image forming system when “before cutting is a right-open book and when the reversed double-sided DF is used” will be described with reference to FIG. The state of the document before and after cutting is as 801. When this original is read by the reverse double-sided DF, as shown in 802, the left margin of the back side image becomes small.

  At this time, the difference between the length of the original drawn from the DF and the set original size is calculated when each page is read (step S512). Here, when the original is the front side, it is not necessary to correct the margin as shown in 802 of FIG. 8 described above. Therefore, it is necessary to determine whether the front side is read or the back side is read. (Step S513). When the difference between the document length and the document size is calculated by reading the back surface of the document, the image on the back surface is shifted to the right by the calculated size width (step S514), and the page (back surface) Are stored (step S516).

  If the difference between the document length and the document size is calculated by reading the front side of the document, the margin correction is not required, and the read image of the page is stored as it is (step S515).

  As a result, “the state stored as an image to be transmitted” in “when the reversed double-sided DF is used with a right-open book before cutting” is a state in which the margin width is adjusted as represented by 803 in FIG.

  If the 1-pass double-sided DF is mounted in step S511, the front side and the back side are read simultaneously when reading a double-sided original. Here, the state of image processing in the actual image forming system when “before cutting is a right-open book and using a one-pass duplex DF” will be described with reference to FIG. The state of the document before and after cutting is as indicated by 901. When this original is read with a one-pass double-sided DF, as shown in 902, it is not necessary to correct margins on both the front and back sides. For this reason, the read two-page image is stored as it is (step S516).

  As a result, “the state stored as an image to be transmitted” in “when the right-open book before cutting and the 1-pass double-sided DF is used” is a state in which the margin width is adjusted as represented by 903 in FIG.

  The margin adjustment process is performed for each page read in this way. Whether all the pages have been read can be determined by reading all the documents on the DF (step S105). If the document still remains, the image is accumulated while step S103 and step S104 are repeated for each page. When all the originals have been read, the transmission process described above with reference to FIGS. 2 and 3 is performed (step S106).

  As described above, an image having means for discriminating whether or not it is a cut document, reader device with DF, means for adjusting left and right margins, means for accumulating images, and means for transmitting images In the forming system, the image read using the reader device with DF is analyzed and determined to be a cut document. If the original is double-sided, the result of reading a plurality of pages according to the type of DF If the margin widths at both ends of the front and back sides are different, convert the left and right margin widths to an image corrected for the type of DF, send it to an e-book reader or counter device after adjusting the appearance. You can read the document as it is.

[Second Embodiment]
In the first embodiment, the means for determining whether or not the document is cut, the reader device with DF, the means for adjusting the left and right margins, the means for storing the image, and the image are transmitted. In the image forming system having the means, the image read using the reader device with DF is analyzed and determined to be a cut document. If the original is double-sided, the result of reading a plurality of pages according to the type of DF In the second embodiment, when the margin widths at both ends in the sub-scanning direction are different between the front side and the back side, the left and right margin widths are converted to an image corrected according to the type of DF. A reader with DF in an image forming system having means for discriminating whether or not it is a document, reader device with DF, means for adjusting left and right margins, means for storing images, and means for transmitting images Using equipment If the scanned image is analyzed and determined to be a cut document, and the original is double-sided, even when scanned from the platen, the result of scanning multiple pages is that the margin width at both ends in the sub-scanning direction is the front side. 4 and FIG. 10 to FIG. 13 in the case where the left and right margin widths are converted into images corrected separately for the front and back surfaces and sent to an e-book reader or counter device after the appearance has been adjusted. Will be described.

  FIG. 10 is a diagram showing a sequence of adjusting the margin width and adjusting the appearance when the cut document described in the present invention is read on the document table and then transmitting it to the electronic book or the counter machine. . FIG. 4 is a diagram showing a screen flow for setting a mode for transmitting a cut document. FIG. 11 is a diagram showing a sequence of margin width adjustment processing when reading from the document table depending on the type of the cut document (left-open or right-open). FIGS. 12 and 13 show the actual image processing state in the image forming system for two patterns when reading from the document table depending on the type of the cut document (left open or right open) shown in FIG. FIG.

  First, using the operation panel unit 208 of the image forming system, a mode for reading and transmitting a cut document is set (step S1001). The operation status at this time will be described with reference to FIG.

  When a “user mode” key (not shown) is pressed to display a setting screen (step S401), a user mode main screen is displayed (step S402).

  In this example, the user mode main screen includes "common specification setting", "timer setting", "adjustment / cleaning", "report specification setting", "system management setting", "copy specification setting", "send / There are “Receive specification setting”, “Box specification setting”, “Printer specification setting”, “Destination table specification setting”, and when “Send / Receive specification setting” is pressed from here, the Send / Receive specification setting screen is displayed ( Step S403).

  The transmission / reception specification setting screen includes “send document after cutting” in addition to “transmission specification setting” and “reception specification setting”. When the “send cut document” key is pressed on the transmission / reception specification setting screen, a setting screen for sending the cut document is displayed (step S404). On the setting screen for transmitting the document after cutting, it is possible to set whether the bookbinding document before cutting is a left-open book or a right-open book. When either the “left open” key or the “right open” key is pressed and then the “close” key is pressed, the cut document is set to be transmitted.

  Thereafter, a transmission destination such as an electronic book or a counter device for actually transmitting a document is specified, and a transmission mode such as a size of a document to be transmitted, a duplex mode, and a file format is specified (step S405).

  When the mode setting for reading and transmitting the document cut in step S1001 is completed, the cut document is placed on the document table (step S1002).

  After the mode setting and document setting, the document reading is started by pressing the start key (step S1003), and the document on the document table is read by the reader device 218.

  The read image data is subjected to margin amount adjustment processing for each page according to the left / right opening method set in step S404 (step S1004). A sequence of margin width adjustment processing at this time will be described with reference to FIG.

  First, it is determined whether the document specified in step S404 is “left open” or “right open” (step S1101). If “left open” is specified, the process proceeds to step S1102. Here, the state of image processing in the actual image forming system when “reading from the document table with a left-open book before cutting” will be described with reference to FIG. The state of the document before and after cutting is as 1201. When this document is read on the document table, the right margin of the back side image is reduced as represented by 1202.

  At this time, the difference between the length of the document read on the document table and the set document size is calculated when each page is read (step S1102). Here, when the original is the front side, it is not necessary to correct the margin as shown in 1202 of FIG. 12, and it is necessary to determine whether the front side is read or the back side is read. Yes (step S1103).

  When the difference between the document length and the document size is calculated by reading the front side of the document, it is not necessary to correct the margin, so the read image of the page is stored as it is (step S1105).

  When the difference between the document length and the document size is calculated by reading the back surface of the document, the image on the back surface is shifted to the left by the calculated size width (step S1104), and the page (back surface) Are stored (step S1105).

  As a result, “the state stored as an image to be transmitted” in “when reading from the document table with a left-open book before cutting” is a state in which the margin width is adjusted as represented by 1203 in FIG.

  If “right open” is designated in step S1101, the process proceeds to step S1106. Here, the state of image processing in the actual image forming system “when reading from the document table with a right-open book before cutting” will be described with reference to FIG. The state of the document before and after cutting is as indicated by 1301. When this document is read on the document table, the right margin of the front side image is reduced as indicated by 1302.

  At this time, the difference between the length of the document read on the document table and the set document size is calculated when each page is read (step S1106). Here, when the original is the back side, it is not necessary to correct the margin as shown in 1302 of FIG. 13 described above, so it is necessary to determine whether the front side is read or the back side is read. Yes (step S1107).

  When the difference between the document length and the document size is calculated by reading the front side of the document, the front side image is shifted to the left by the calculated size width (step S1108), and the page (front side) Are stored (step S1109).

  If the difference between the document length and the document size is calculated by reading the back side of the document, margin correction is unnecessary, and the read image of the page is stored as it is (step S1109).

  As a result, the “save state as an image to be transmitted” of “when reading from the document table with a right-open book before cutting” is a state in which the margin width is adjusted as represented by 1303 in FIG.

  The margin adjustment process is performed for each page read in this way. It is determined whether all pages have been read (step S1005). If the document still remains, the image is accumulated while the steps S1002 to S1004 are repeatedly performed on each page while replacing the document. When all the originals have been read, the transmission process described above with reference to FIGS. 2 and 3 is performed (step S1006).

  As described above, an image having means for discriminating whether or not it is a cut document, reader device with DF, means for adjusting left and right margins, means for accumulating images, and means for transmitting images In the forming system, the image read using the reader device with DF is analyzed and determined to be a cut document. If the original is double-sided, even if it is read from the original table, the result of reading a plurality of pages is If the margin width at both ends in the scanning direction is different between the front and back surfaces, convert the left and right margin widths to images that have been individually corrected for the front and back surfaces, and send them to an e-book reader or counter device after adjusting the appearance. As a result, the received document can be read as it is.

  When adjusting the margin amount, the entire original is read, and it is determined whether or not to adjust the margin amount separately for the front side and the back side.

  Further, for the document data whose margin amount is a certain value or more, control is performed so that the margin amount is not adjusted.
