Description

The present invention is a multifunction device including a document reading device and a document scanning method for reading a document, an image processing device for processing a scanned image acquired from a document read by the document reading device, and the document reading device and the image processing device. Regarding.

The document reading device is used to acquire image data of a document, print based on the image data, and generate an image data file including the image data. Further, the document reading device device generates a scanning result based on the functions and settings currently selected for the document reading device and the image data acquired from the document. For example, when a setting for reading a document of a predetermined size and a predetermined orientation (for example, A4 size landscape orientation) is selected for the document reading device, that orientation (for example, A4 size landscape orientation) is selected for that size. On the premise that the original document is read, printing and file generation are performed based on the image data acquired from the original document. When the function of the aggregation function of a predetermined number of sheets (for example, 4 sheets) is selected, the predetermined number of sheets (for example, 4 sheets) is aggregated into one output page. Further, when the single-sided / double-sided printing function is selected, the images of the two originals are printed on the front side and the back side of one sheet. Further, when the double-sided / single-sided printing function is selected, the front side image and the back side image of one original sheet are printed on one side of one sheet of paper. Furthermore, when the mass original mode function is selected, multiple originals are divided into multiple groups (for example, 300 originals are divided into three groups), and only the original reading is performed for each group. Is completed for all groups, and then printing or image data file output is performed for the manuscripts of all groups.

Japanese Patent No. 4054756

However, when the above functions and settings are selected, it is not always possible to obtain a reading result that is normally judged to be normal due to an erroneous operation or intention by the user. It was.

For example, the user may select a setting for the document scanning device to read a document of a predetermined size and a predetermined orientation, cause the document to read a document of a different size, or read a document of the same size. It may cause the document to be read in the correct orientation.

Further, even if the function of the aggregation function for a predetermined number of sheets is selected by the document reading device, the user may not allow the document reading device to read the originals so that the aggregated number of documents corresponds to the output of one sheet.

Further, even if the user selects the single-sided / double-sided printing function for the document reading device, for example, after reading the first document, the first document is used as the second document. Sometimes I forget to change to.

Furthermore, even if the user selects the double-sided / single-sided printing function for the document reader, the user may forget to turn over the paper or card after reading the front side of the paper or card. is there.

Further, even if the user selects the function of the mass original mode for the original reading device and sets the size and orientation of the paper, the orientation of the original to be read may be wrong in any of the groups. is there.

In such a case, the function and setting currently selected for the document reading device cannot normally obtain the reading result by the function and setting.

Patent Document 1 discloses an invention in which a preview is displayed each time a manuscript is read for each group in a mode similar to the mass manuscript mode. However, since the preview is performed for all groups regardless of whether the reading result is normal or not, for example, if the number of groups is large, the burden on the user becomes heavy, and the reading result is normal. Since the user has to make a judgment as to whether or not there is, the burden becomes heavy, and there is a possibility that the user may overlook something that is not normal.

Therefore, according to the present invention, when a normal output image cannot be obtained by processing with an image processing device set based on a scanned image acquired from a document, the user can deal with it without burden. It is an object of the present invention to provide a document reading device, an image processing device, a multifunction device, and a document scanning method.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

[First Embodiment]
The first embodiment is a case where the scanned document is read in a different direction even though the document placed in a predetermined direction is set to be read. is there.

For example, as shown in FIG. 1 (a), although the A4 horizontal scan range is set, as shown in FIG. 1 (b), an A4 size document is placed vertically on the platen. When the automatic document processing device is set in the vertical direction, a preview screen showing this is displayed in the preview area 303 of the screen 301 shown in FIG. 14, as shown in FIG. 1 (c). On this preview screen, a setting rectangle indicating the scanning range in the A4 width and a scanning rectangle indicating that the document was actually read in the A4 portrait are displayed. For example, the setting rectangle is shown only by the frame showing the scan range, and the reading rectangle is shown by a predetermined fill. As the predetermined fill, for example, a predetermined figure, an actual read image, or the like is used. Further, in the predetermined fill, the inside of the setting rectangle and the outside of the setting rectangle may be filled differently from each other.

In addition to the preview screen, the screen display unit displays a user interface screen (a portion other than the preview area 303 of the screen 301 shown in FIG. 14) used for allowing the user to select a corresponding method. At this point, printing is not executed.

If resetting (“change of setting” 311 on screen 301) is selected on this user interface screen, the reading direction of the document is changed, and the document is read again. For example, an A4 portrait scan range is set and the document is scanned in A4 portrait. The scan range in the A4 landscape may be set again, and the document may be scanned in the A4 landscape.

If reloading (“Redo 1st sheet” 309 on screen 301) is selected on this user interface screen, the document is read again while maintaining the settings related to the size and reading direction of the document. For example, the original is read in the A4 landscape while maintaining the scan range in the A4 landscape.

If the same error as the previous time or other error is not detected as a result of resetting and reloading by selecting reset, or reloading by selecting reload, the preview screen is not displayed in particular. At that point, print or output.

If continuation (“Next” 313 on screen 301) is selected on the above user interface screen, the process proceeds to printing or output processing regardless of error detection.

Further, when the A4 horizontal scan range is set and the A4 size document is placed on the platen in the horizontal direction or set in the automatic document processing device in the horizontal direction, FIG. 1 (c) The process is continued as it is without displaying the preview screen as shown in (1) or the above user interface screen (without displaying the screen 301), and the process proceeds to printing or output.

If the set paper size and the size of the actually read original are different, the set paper size and the size of the actually read original are different, and the set paper orientation and the read paper are different. The same thing can be done when the orientations of the are different.

The size and orientation of the actually read document are detected by a predetermined method. For example, the size and orientation of the document placed on the platen may be detected by using a plurality of sensors provided at the bottom of the platen to detect the size and orientation of the document. The size and orientation of the original placed on the platen may be detected by image processing the scanned image obtained by scanning the original, or the size and orientation of the original may be detected based on the scanned image. May be good. If the set original size and orientation do not match the detected original size and orientation, a preview screen or the like will be displayed. That is, for example, if the size and orientation of the document are set, it is a requirement corresponding to the setting that the size and orientation of the detected document match, but if this requirement is not satisfied, A preview screen etc. will be displayed.

Further, the orientation (vertical or horizontal) of the scanned document can be set by each user's operation, but the administrator can set the default orientation for each application of the scanned document. Specifically, the administrator can set the default direction of the scanned document for each function such as copy, fax, scan to PC, and server save according to the convenience store, company, and the like. The system settings are stored in the confirmation table provided on the recording medium.

[Second Embodiment]
In the second embodiment, although the automatic document processing apparatus is set to read all the documents placed in a predetermined direction, the collectively read documents are read in a different direction. This is the case when it is done.

For example, as shown in FIG. 1 (a), although the A4 horizontal scan range is set, as shown in FIG. 1 (b), a plurality of A4 size documents are sent to the automatic document processing device. When these documents are read in the vertical direction, a preview screen showing this is displayed in the preview area 303 of the screen 301 shown in FIG. 14, as shown in FIG. 1 (c). On this preview screen, a setting rectangle indicating the scanning range in the A4 width and a scanning rectangle indicating that the document was actually read in the A4 portrait are displayed. For example, the setting rectangle is shown only by the frame showing the scan range, and the reading rectangle is shown by a predetermined fill. As the predetermined fill, for example, a predetermined figure, an actual scanned image (an image of any one of the scanned originals), or the like is used. Further, in a predetermined fill, different fills may be applied to the inside of the setting rectangle and the outside of the setting rectangle.

In addition to the preview screen, the screen display unit displays a user interface screen (a portion other than the preview area 303 of the screen 301 shown in FIG. 14) used for allowing the user to select a corresponding method.

If resetting (“change of setting” 311 on screen 301) is selected on this user interface screen, the reading direction of the document is changed, and the document is read again. For example, an A4 portrait scan range is set, and a plurality of documents are collectively scanned in A4 portrait. The scanning range of A4 landscape may be set again, and a plurality of documents may be scanned together in A4 landscape.

If reloading (“Redo 1st sheet” 309 on screen 301) is selected on this user interface screen, the reading of a plurality of documents is recombined while maintaining the settings related to the size and reading direction of the documents. To do it. For example, while maintaining the scanning range of A4 landscape, a plurality of documents are collectively scanned in A4 landscape.

If the same error as the previous time or other error is not detected as a result of resetting and reloading by selecting reset, or reloading by selecting reload, the preview screen is not displayed in particular. At that point, print or output.

If continuation (“Next” 313 on screen 301) is selected on the above user interface screen, the process proceeds to printing or output processing regardless of error detection.

Further, when the A4 horizontal scan range is set and the A4 size document is set in the horizontal direction in the automatic document processing device, the preview screen as shown in FIG. 1C is also the above user interface. The process is continued without displaying the screen (without displaying the screen 301), and the process proceeds to printing or output.

The first embodiment corresponds to the processing of one sheet at a time, while the second embodiment corresponds to the processing of a plurality of sheets at a time. For example, when 30 originals are placed on the document feeder, if the originals are placed in the wrong direction, it is possible to avoid printing in the wrong direction.

Also, for example, when reading and printing or outputting 300 sheets, instead of doing this all at once, the manuscript is read in 3 steps of 100 sheets each, and finally 300 sheets are printed or printed together. There is an operation mode to output, but if there is an error in the placement direction of the scanned document on the document feeder at any time, a preview screen to show it and a user interface screen to let the user select the corresponding method. Is displayed, and the corresponding method selected there can be used to read the error-free state, so that the error can be corrected in units of each time. Further, since the preview screen and the user interface screen are displayed only when an error is detected, it is possible to avoid displaying the preview screen or the like unnecessarily.

The size and orientation of the actually read document are detected by a predetermined method. In the first embodiment, since the original is placed on the platen, the original is placed on the platen by using a plurality of sensors provided at the bottom of the platen to detect the size and orientation of the original. Although the size and orientation could be detected, in the second embodiment, the size and orientation of the document may be detected by the automatic document processing device, or the size and orientation of the document may be detected based on the scanned image itself. It may be detected. The size and orientation of the document placed on the platen may be detected by performing image processing on the scanned image obtained by scanning the document. If the set original size and orientation do not match the detected original size and orientation, a preview screen or the like will be displayed. That is, for example, if the size and orientation of the document are set, it is a requirement corresponding to the setting that the size and orientation of the detected document match, but if this requirement is not satisfied, A preview screen etc. will be displayed.

[Third Embodiment]
The third embodiment is a case where the scanned document occupies only a part of the document reading area set in the document reading device.

For example, as shown in FIG. 2 (a), when the A4 vertical document is read even though the A3 horizontal scan range is set, as shown in FIG. 2 (b), FIG. A preview screen showing this as shown in (c) is displayed in the preview area 303 of the screen 301 shown in FIG. On this preview screen, a setting rectangle indicating the scanning range in the A3 width and a scanning rectangle indicating that the document was actually read in the A4 portrait are displayed. For example, the setting rectangle is shown only by the frame showing the scan range, and the reading rectangle is shown by a predetermined fill. As the predetermined fill, for example, a predetermined figure, an actual read image, or the like is used.

In addition to the preview screen, the screen display unit displays a user interface screen (a portion other than the preview area 303 of the screen 301 shown in FIG. 14) used for allowing the user to select a corresponding method. At this point, printing is not executed.

If resetting (“change of settings” 311 on screen 301) is selected on this user interface screen, the reading size and direction of the document are changed, and the document is read again. For example, an A4 portrait scan range is set and the document is scanned in A4 portrait. You may set the scanning range of A4 landscape and scan the document in A4 landscape. However, depending on the document reading device, either one may not be possible.

Further, if reloading (“Redo the first sheet” 309 on the screen 301) is selected on this user interface screen, the document is read while maintaining the reading direction of the document. For example, the A3 document is read in landscape orientation while maintaining the scanning range of A3 landscape.

Further, if continuation (“Next” 313 on screen 301) is selected on this user interface screen, the process proceeds to printing or output as it is. This is intended in particular, when a scan range larger than that of the original is set and a margin for writing a memo is created in the print result.

If the operation corresponding to the resetting and reloading or reloading is executed and the same error as the previous time is not detected, printing or output is executed at that point.

When the A3 horizontal scan range is set and the A3 size document is placed on the platen in the horizontal direction or set in the automatic document processing device in the horizontal direction, FIG. 2 (c) shows. Without displaying the preview screen as shown or the above user interface screen (without displaying the screen 301), the process is continued as it is, and the process proceeds to printing or output.

The size and orientation of the actually read document are detected by a predetermined method. For example, the size and orientation of the document placed on the platen may be detected by using a plurality of sensors provided at the bottom of the platen to detect the size and orientation of the document. The size and orientation of the original placed on the platen may be detected by image processing the scanned image obtained by scanning the original, or the size and orientation of the original may be detected based on the scanned image. May be good. .. If the set original size and orientation do not match the detected original size and orientation, a preview screen or the like will be displayed. That is, for example, if the size and orientation of the document are set, it is a requirement corresponding to the setting that the size and orientation of the detected document match, but if this requirement is not satisfied, A preview screen etc. will be displayed.

[Fourth Embodiment]
The fourth embodiment is a case where the predetermined number of documents cannot be read even though the aggregation function for the predetermined number of sheets is set.

For example, as shown in FIG. 3 (a), when the aggregation function of four sheets is set, but as shown in FIG. 3 (b), only two sheets of the original are read. As shown in 3 (c), a preview screen showing this is displayed in the preview area 303 of the screen 301 shown in FIG. In this preview screen, four setting rectangles indicating the document area for four sheets and two reading rectangles indicating that only two documents were actually read are displayed. For example, the setting rectangle is shown only by a frame showing the range occupied after aggregation, and the reading rectangle is shown by a predetermined fill indicating the area occupied after aggregation. As the predetermined fill, for example, a predetermined figure, an actual read image, or the like is used.

In addition to the preview screen, the screen display unit displays a user interface screen (a portion other than the preview area 303 of the screen 301 shown in FIG. 14) used for allowing the user to select a corresponding method. At this point, printing is not executed.

If resetting (“change of settings” 311 on screen 301) is selected on this user interface screen, the parameters of the aggregation function are changed, and the original is read again. For example, it is set to aggregate two sheets and two documents are read.

If all reloading (“Redo 1st sheet” 309 on screen 301) is selected on this user interface screen, 4 originals including the already read original are read.

If the operation corresponding to the resetting and reloading or reloading is executed and the same error as the previous time is not detected, printing or output is executed at that point.

If continuation (“Next” 313 on screen 301) is selected on the above user interface screen, the process proceeds to printing or output processing regardless of error detection. That is, in this example, the content is printed or output so that the image data exists only in only two areas out of the four areas.

In addition, when four sheets of originals are set to be aggregated and four sheets of documents are read, neither the preview screen as shown in FIG. 3C nor the above user interface screen is displayed (screen 301 is displayed). Do not), continue processing and proceed to printing or output.

The number of documents actually read is detected by a predetermined method. For example, the number of times the image is actually read may be the number of scanned documents. If the set original size and orientation do not match the detected original size and orientation, a preview screen or the like will be displayed. In other words, if the total number of sheets is set, it is a requirement that the number of scanned documents matches these, but if this requirement is not met, a preview screen etc. will be displayed. Become.

[Fifth Embodiment]
The fifth embodiment is a case where the same original image is read in succession after the single-sided / double-sided copying (the one in which two sheets are aggregated on the front side and the back side) is set.

For example, as shown in FIG. 4 (a), when the same original is continuously read even though the single-sided / double-sided copying function is set, as shown in FIG. 4 (b). As shown in FIG. 4C, a preview screen showing this is displayed in the preview area 303 of the screen 321 shown in FIG. 7. On this preview screen, a scanning rectangle indicating the front surface of the scanned document and a scanning rectangle indicating the back surface of the scanned document are displayed. For example, each reading rectangle is shown with a predetermined fill. As the predetermined fill, for example, a predetermined figure, an actual read image, or the like is used. The user can recognize that the same original is continuously read from the screen in which the same figures are displayed side by side or the same scanned images are displayed side by side. In addition, if a message is displayed, it is possible to recognize that the same original has been continuously read with the help of the message.

In addition to the preview screen, the screen display unit displays a user interface screen (a portion other than the preview area 303 of the screen 321 shown in FIG. 14) used for allowing the user to select a corresponding method. At this point, printing is not executed.

If resetting (“change setting” 331 on screen 321) is selected on this user interface screen, for example, the single-sided / double-sided copying function is changed to the single-sided / single-sided copying function. After that, the original is reloaded. This assumes, for example, that the user originally intended single-sided / single-sided copying, but mistakenly set the single-sided / double-sided copying function. In addition, it is assumed that the settings for single-sided / double-sided copying and the read original are not originally intended.

Further, if all reloading (“return” 325 of screen 321) is selected on this user interface screen, the first and second originals are reloaded.

Further, if reloading from the continuation (“Reread the second sheet” 329 on the screen 321) is selected on this user interface screen, only the second document is reloaded.

If the operation corresponding to the resetting and reloading or reloading is executed and the same error as the previous time is not detected, printing or output is executed at that point.

If continuation (“Next” 333 on screen 321) is selected on the above user interface screen, printing or output will be performed regardless of error detection (including cases where it is not an error from the user's point of view). Proceed to processing. That is, in this example, image data having the same content is printed or output on both sides.

Further, when single-sided / double-sided copying is set and two different image data are acquired, neither the preview screen as shown in FIG. 4C nor the above user interface screen is displayed (screen). (Without displaying 321), continue the process as it is, and proceed to printing or output.

Whether or not the scanned images of the two actually scanned documents are the same is detected by comparing the scanned images with each other. If they match or almost match, a preview screen or the like is displayed. That is, if single-sided / double-sided copying is set, it is a requirement corresponding to the setting that the two scanned images differ by a predetermined amount or more according to a predetermined evaluation method, but if this requirement is not satisfied, a preview is performed. The screen etc. will be displayed.

If single-sided / double-sided copying is set so that the user can check the contents to be printed on both sides, the preview screen is displayed regardless of whether the two acquired images are the same or different. You may try to do it. In this case, if the requirements for single-sided / double-sided copying settings are defined, the requirements will not always be met.

[Sixth Embodiment]
The sixth embodiment is a case where the same original image is read in succession after the setting of double-sided / single-sided copying (the one in which one front surface and the back surface are integrated into one single side) is set. is there.

For example, as shown in FIG. 5 (a), when the same original is continuously read even though the double-sided / single-sided copying function is set, as shown in FIG. 5 (b). As shown in FIG. 5C, a preview screen showing this is displayed in the preview area 303 of the screen 321 shown in FIG. In this preview screen, a scanning rectangle indicating the front surface scanning document, a scanning rectangle indicating the back surface scanning document, and a paper rectangle representing the paper containing these are displayed. For example, the paper rectangle is shown only by a frame, and each reading rectangle is shown by a predetermined fill. As the predetermined fill, for example, a predetermined figure, an actual read image, or the like is used. The user can recognize that the same original has been continuously read from the screen in which the same figures are displayed side by side or the same scanned images are displayed side by side. In addition, if a message is displayed, it is possible to recognize that the same original has been continuously read with the help of the message.

In addition to the preview screen, the screen display unit displays a user interface screen (a portion other than the preview area 303 of the screen 321 shown in FIG. 14) used for allowing the user to select a corresponding method. At this point, printing is not executed.

If resetting (“change setting” 331 on screen 321) is selected on this user interface screen, for example, the double-sided / single-sided copying function is changed to the single-sided / single-sided copying function. After that, the original is reloaded. This assumes, for example, that the user originally intended to be non-aggregate, but mistakenly set the double-sided / single-sided copy function. In addition, it is assumed that the settings and the read original are not originally intended.

Further, if all reloading (“return” 325 of screen 321) is selected on this user interface screen, the first and second originals are reloaded.

Further, if reloading from the continuation (“Reread the second sheet” 329 on the screen 321) is selected on this user interface screen, only the second document is reloaded.

If the operation corresponding to the resetting and reloading or reloading is executed and the same error as the previous time is not detected, printing or output is executed at that point.

If continuation (“Next” 333 on screen 321) is selected on the above user interface screen, printing or output will be performed regardless of error detection (including cases where it is not an error from the user's point of view). Proceed to processing. That is, in this example, two image data having the same content are printed or output on one side.

Further, when double-sided / single-sided copying is set and two different image data are acquired, neither the preview screen as shown in FIG. 5 (c) nor the above user interface screen is displayed (screen). (Without displaying 321), continue the process as it is, and proceed to printing or output.

Whether or not the scanned images of the two actually scanned documents are the same is detected by comparing the scanned images with each other. If they match or almost match, a preview screen or the like is displayed. That is, if double-sided / single-sided copying is set, it is a requirement corresponding to the setting that the two scanned images differ by a predetermined amount or more according to a predetermined evaluation method, but if this requirement is not satisfied, a preview The screen etc. will be displayed.

The operation panel unit 217 includes a display unit 211 that displays predetermined information, and an input unit 203 that allows the user to input instructions to the document reading device 820 and the multifunction device main body 215. In the present embodiment, the operation panel unit 217 is arranged on the front side of the reading device main body 822. The front side corresponds to the front side of the paper surface of FIG. 6, and the back side corresponds to the back side of FIG.

As shown in FIG. 7, the arithmetic processing unit 213 includes a CPU 213a that drives and controls the sheet feeding unit 10, the manual feeding unit 20, the image forming unit 30, and the document reading device 820, and various programs for operating the CPU 213a. It is provided with a memory 213b for storing various information and the like used by the CPU 213a. The arithmetic processing unit 213 integrates and controls the operations of the sheet feeding unit 10, the manual feeding unit 20, the image forming unit 30, and the document reading device 820 based on the operation of the operation panel unit 217 by the user. Let the sheet form an image.

The arithmetic processing unit 213 may include controlling the operation of the document reading device 820.

Next, an image forming operation (image forming control by the arithmetic processing unit 213) by the multifunction device 800 configured as described above will be described. In the present embodiment, the image forming unit 30 forms the image of the scanned document fed by the document automatic feeding unit 824 and read by the reading device main body 822 on the sheet fed by the sheet feeding unit 10. An image forming operation will be described as an example.

When the image formation start signal is transmitted by the input to the input unit 203 of the operation panel unit 217 by the user, the scanned document placed on the document automatic feeding unit 824 by the user is automatically directed toward the document reading position. The image is fed and the image is read by the reading device main body 822 at the document reading position.

When the image of the original document is read by the scanning apparatus main body 822, the exposure apparatus 32 irradiates the photoconductor drums 740Y to 740K with a plurality of laser beams corresponding to each image based on the image information of the scanned document. At this time, the photoconductor drums 740Y to 740K are precharged by the chargers 741Y to 741B, respectively, and the corresponding electrostatic latent laser beams are irradiated on the photoconductor drums 740Y to 740K. An image is formed. After that, the electrostatic latent images formed on the photoconductor drums 740Y to 740K are developed by the developing devices 742Y to 742K, and yellow (Y), magenta (M), and cyan (C) are developed on the photoconductor drums 740Y to 740K. ) And black (K) toner images are formed. The toner images of each color formed on the photoconductor drums 740Y to 740K are superimposed and transferred to the intermediate transfer belt 35 by the primary transfer rollers 36Y to 36K, and the superimposed transferred toner image (full-color toner image) is the intermediate transfer belt. It is conveyed to the nip portion N while being supported on the 35.

In parallel with the image forming operation described above, the sheets loaded on the sheet loading section 11 are fed to the sheet transport path 26 by the pickup roller 15 while being separated one by one by the separate feeding section 12. Then, the resist roller pair 27 located upstream in the sheet transport direction of the nip portion N corrects the skew and transports the nip portion N to the nip portion N at a predetermined transfer timing. A full-color toner image carried by the intermediate transfer belt 35 is transferred to the sheet conveyed to the nip portion N by the secondary transfer roller 37.

The sheet on which the toner image is transferred is heated and pressurized by the fixing unit 34 to melt and fix the toner image, and is discharged to the outside of the device by the discharge roller pair 18. The sheet discharged to the outside of the device is loaded on the discharge sheet loading unit 19.

When an image is formed on both sides (first surface and second surface) of the sheet, the discharge roller pair 18 is rotated in the reverse direction before the sheet on which the image is formed on the first surface is discharged to the outside of the apparatus. It is conveyed to the double-sided transport path 17, and is re-conveyed to the image forming unit 30 via the double-sided transport path 17. Then, as with the first surface, an image is formed on the second surface and discharged to the outside of the device. The sheet discharged to the outside of the device is loaded on the discharge sheet loading unit 19.

The function / setting input unit 213-1 accepts selection and change of functions and settings from the user.

The reading unit 213-3 receives the image data of the document read by the reading device main body 822.

The scanning result generation unit 213-5 generates a scanning result based on the functions and settings selected or changed by the function / setting input unit 213-1 and the image data of the original document received by the scanning unit 213-5.

The reading result evaluation unit 213-7 evaluates the reading result generated by the reading result generation unit 213-5 and determines whether or not it is normal.

When the reading result is not normal, the screen display control unit 213-9 displays the preview screen and the user interface screen on the display unit 211 of the operation panel unit 217.

The additional processing execution control unit 213-11 makes a predetermined judgment according to the input from the user to the operation panel unit 217, and based on the determination, the function / setting input unit 213-1, the reading unit 213-3, and the reading result. It controls the generation unit 213-5.

The first embodiment is a specific example of the operation corresponding to the first embodiment and the third embodiment. Note that this operation may be executed by the arithmetic processing unit 213 in the seventh embodiment. This also applies to other examples.

With reference to FIG. 9, first, the finished paper size is set (step S401).

Next, the orientation of the paper is set (step S403).

Next, the original is read (step S405).

Next, the paper size and orientation set in steps S403 and S405 are compared with the size and orientation of the document read in step S405 (step S407).

If the size and orientation are the same between the two (“same” in step S407), the process proceeds to step S411. If at least one of the size and orientation is different (“different” in step S407), the process proceeds to step S409.

In step 409, the user is provided with a preview screen and a corresponding method indicating that the size and orientation of the original read in step S405 do not match the paper size and orientation set in steps S403 and S405. Display the user interface screen used to make a selection.

If there is an input for selecting a setting change as a corresponding method (pressing the "change setting" button on the screen 301) with respect to the user interface screen displayed in step 409, the process returns to step S401. After returning to step S401, the paper size setting (step S401), the paper orientation setting (step S403), and the document reading (step S405) are executed again, and the process proceeds to step S407. For example, if the size of the originals does not match, the size of the finished paper is adjusted to the size of the original read in step 405 (step S401), the same print orientation as the previous time is set (step S403), and the previous time. The same original as is read in the same direction (step 405), and the process proceeds to step S407. Also, for example, if the orientations of the papers do not match, the size of the finished paper is the same as the previous one (step S401), and the print orientation is set to the orientation in which the original is actually read (the orientation that was read last time). The matching setting is made (step S403), the same original as the previous one is read in the same direction (step S405), and the process proceeds to step S407.

If there is an input for selecting rereading of the original as a corresponding method for the user interface screen displayed in step 409, the process returns to step S405. After returning to step S405, the reading of the original (step S405) is executed again, and the process proceeds to step S407. For example, a document having the same size as the finished paper size set in step S401 is read in the same orientation as the orientation set in step S403 (step S405), and the process proceeds to step S407.

For the user interface screen displayed in step S409, select to proceed in the same manner as when the size and orientation of the finished paper set in steps S401 and S403 and the size and orientation of the document read in step S605 are the same. If there is an input for, the process proceeds to step S411.

In step S411, the user presses the print start button, and printing is executed in accordance with this (step S413). Prior to the execution of printing, the reading result to be printed is generated according to the settings and functions and the read original. Further, instead of printing, a print image or data describing the print contents may be output. This also applies to other examples.

Further, when the change of the setting is selected, step S601 and step S603 may be executed, and then step S605 may not be executed. In this case, prior to printing, the read result to be printed is generated according to the changed settings and functions and the originally read original. This also applies to other examples.

The second embodiment is a specific example of the operation corresponding to the second embodiment.

With reference to FIG. 10, first, the finished paper size is set (step S421).

Next, the orientation of the paper is set (step S422).

Next, the manuscript is set by the user (step S425). The manuscript set here is one or more manuscripts of the first time.

Next, the start button is pressed by the user (step S427).

Next, document reading is executed (step S429). Here, the document to be read is one or more original documents of the first time set in step S425.

Next, the paper size and orientation set in steps S421 and S423 are compared with the size and orientation of the document read in step S429 (step S431).

If the size and orientation are the same between the two (YES in step S431), the process proceeds to step S437. If at least one of the size and orientation is different (NO in step S431), the process proceeds to step S435.

In step 435, the user is provided with a preview screen and a corresponding method indicating that the size and orientation of the original read in step S429 do not match the paper size and orientation set in steps S421 and S423. Display the user interface screen used to make a selection.

If there is an input for selecting a setting change as a corresponding method (pressing the "change setting" button on the screen 301) with respect to the user interface screen displayed in step 435, the process returns to step S421. After returning to step S421, the paper size setting (step S421), the paper orientation setting (step S423), the original reading (step S429), and the like are executed again, and the process proceeds to step S431. For example, if the size of the originals does not match, the size of the finished paper is adjusted to the size of the original read in step S429 (step S421), the same print orientation as the previous time is set (step S423), and the previous time. The same original as is read in the same direction (step 429), and the process proceeds to step S431. Further, for example, if the orientations of the papers do not match, the size of the finished paper is made the same as the previous one (step S421), and the print orientation is set to the orientation in which the original is actually read (the orientation in which the original was read last time). The matching setting is made (step S423), the same original as the previous one is read in the same direction (step S429), and the process proceeds to step S431.

If there is an input for selecting rereading of the original as a corresponding method for the user interface screen displayed in step S435, the process returns to step S425. After returning to step S425, reading the original (step S425) or the like is executed again, and the process proceeds to step S431. For example, if the orientations of the papers do not match, a document having the same size as the finished paper size set in step S421 is read in the same orientation as the orientation set in step S423 (an orientation different from the previous one). (Step S429), the process proceeds to step S431.

In step S437, the image data of the original document read in the immediately preceding step S429 is saved.

Next, if the print button is pressed (YES in step S439), printing is executed (step S453). At this point, since there is no manuscript to be additionally read, the additional read button is in a non-selectable state.

Next, the manuscript is set by the user (step S441). The manuscript set here is one or more manuscripts of the second time. As a result, the additional read button becomes selectable.

Next, if the print button is pressed in step S443, printing is executed (step S453). If the additional read button is pressed in step S443, the process proceeds to step S445 for additional read.

In step S445, the document is read. Here, the document to be read is one or more documents set in step S441 executed immediately before.

Next, the paper size and orientation set in steps S421 and S423 are compared with the size and orientation of the original read in step S445, which was executed immediately before (step S447).

If the size and orientation are the same between the two (“same” in step S447), the process proceeds to step S451. If at least one of the size and orientation is different (“different” in step S447), the process proceeds to step S449.

In step S449, the user is provided with a preview screen and a corresponding method indicating that the size and orientation of the original read in step S445 do not match the paper size and orientation set in steps S421 and S423. Display the user interface screen used to make a selection.

If there is an input for selecting rereading of the original as a corresponding method for the user interface screen displayed in step S449, the process returns to step S441. After returning to step S441, the reading of the original repositioned by the user in step S441 (step S445) or the like is executed again, and the process proceeds to step S447. For example, a document having the same size as the finished paper size set in step S421 is read in the same orientation as the orientation set in step S423 (step S445), and the process proceeds to step S447.

If it is determined to be "same" in step S447, the process proceeds to step S451. In step S451, the image data of the original document read in the immediately preceding step S445 is saved.

After that, the process returns to step S439, but the above-described processing is repeated. If the user supplies the original document in two steps, the user presses the print button in step S439, thereby proceeding to step S453 and executing printing. If the user supplies the manuscript in three steps, the third manuscript is supplied in step S441, and the "additional read" button is pressed in step S443, so that step S445 and subsequent steps are executed. If the normal reading is performed, the user presses the print button when returning to step S439, thereby proceeding to step S453 and executing printing.

For the user interface screen displayed in step S431, proceed to the next step in the same manner as when the size and orientation of the finished paper set in steps S421 and S423 and the size and orientation of the document read in step S429 are the same. If there is an input for selection, the process proceeds to step S437.

Further, with respect to the user interface screen displayed in step S449, the next step is performed in the same manner as when the size and orientation of the finished paper set in steps S421 and S423 and the size and orientation of the document read in step S445 are the same. If there is an input for selection, the process proceeds to step S451.

The third embodiment is a specific example of the operation corresponding to the fourth embodiment.

With reference to FIG. 11, first, the finished paper size is set (step S601).

Next, the print function is set (step S603). The printing function here is to consolidate a predetermined number of sheets on one side. This may be applied to single-sided printing or double-sided printing. In this embodiment, when the finished paper size and the paper size of the original are the same, normal aggregation can be performed. Moreover, it is assumed that only one sheet is output.

Next, the original is read (step S605).

Next, the size of the finished paper set in step S601 and the size of the original read in step S605 are compared (step S607).

If the sizes are the same (YES in step S607), the process proceeds to step S611. If the sizes are different (NO in step S607), the process proceeds to step S609.

In step 609, a preview screen indicating that the size of the finished paper set in step S601 and the size of the document read in step S605 are different, and a user interface screen used for allowing the user to select a corresponding method are displayed. ..

If there is an input for selecting a setting change as a corresponding method for the user interface screen displayed in step 609, the process returns to step S601. After returning to step S601, the paper size setting (step S601), the printing function setting (step S603), and the document reading (step S605) are executed again, and the process proceeds to step S607. For example, the finished paper size is matched to the original size read in step 605 (step S601), the same printing function as the previous time is set (step S603), the same original as the previous time is read (step S605), and the step Proceed to S607.

If there is an input for selecting rereading of the original as a corresponding method for the user interface screen displayed in step 609, the process returns to step S605. After returning to step S605, the reading of the original (step S605) is executed again, and the process proceeds to step S607. For example, a document having the same size as the finished paper size set in step S601 is read (step S605), and the process proceeds to step S607.

If there is an input to the user interface screen displayed in step 609 to select the next step as in the case where the finished paper size set in step S601 and the size of the original read in step S605 are the same. The process proceeds to step S611.

In step S611, it is determined whether or not the printing function set in step S603 is set to read a plurality of original sheets on one sheet of paper.

If not (NO in step S611), the process proceeds to step S619. If so (YES in step S611), the process proceeds to step S613.

In step S613, all the second and subsequent originals are read.

Next, the number of pages in the print setting and the number of sheets to be read are compared (step S615). Here, the number of pages in the print setting is, for example, N when the function of consolidating N sheets on one surface and the function of single-sided printing are set. Further, when the function of aggregating N sheets on one side and the function of double-sided printing are set, it is 2 × N.

If both numerical values match (“match” in step S615), the process proceeds to step S619. If the two numerical values are different (“difference” in step S615), the process proceeds to step S617.

In step S619, printing is started, and then printing is executed (step S621).

In step S617, a preview screen indicating that the number of pages in the print setting and the number of sheets to be read are different, and a user interface screen used for allowing the user to select a corresponding method are displayed.

If there is an input for selecting a setting change as a corresponding method on the user interface screen displayed in step 617, the process returns to step S601. This is mainly based on the assumption that the total number of sheets is wrong. In addition, it is assumed that the settings for double-sided printing / single-sided printing are incorrect. After returning to step S601, the paper size setting (step S601), the printing function setting (step S603), and the document reading (step S605) are executed again, and the process proceeds to step S607. For example, make the finished paper size the same as the previous time (step S601), change the number of sheets to be aggregated, and if necessary, change the double-sided printing / single-sided printing (step S603), and read the same original as the previous time (step S601). S605), the process proceeds to step S607. Next, if the conditions are met, step S611: YES → step S613 → step S615: match → step S619 is executed.

If there is an input for selecting rereading of the original as a corresponding method for the user interface screen displayed in step 617, the process returns to step S613. After returning to step S613, the reading of all the second and subsequent originals (step S613) is executed again, and the process proceeds to step S607. For example, step S613 is executed by changing the number of sheets of all the second and subsequent originals. Next, if “match” is obtained in step S615, the process proceeds to step S619. In addition, you may read again from the first sheet. If there is a shortage, only the shortage of the original may be newly read.

If there is an input for selecting the next (proceed as it is) on the user interface screen displayed in step 617, the process proceeds to step S619.

The fourth embodiment is a specific example of the operation corresponding to the fifth embodiment.

With reference to FIG. 12, first, the finished paper size is set (step S461).

Next, the orientation of the paper is set (step S463).

Next, the single-sided / double-sided printing function is set (step S465).

Next, since the single-sided / double-sided printing function is set (YES in step S466), the process proceeds to step S467.

In step S467, the user sets the first original.

Next, the user accepts the press of the start button (step S469).

Next, the document set in step S467 is read (step S471).

Next, the user sets the next original document (step S473).

Next, the user accepts the press of the start button (step S475).

Next, the document set in step S473 is read (step S477).

Next, the image data of the document read in step S471 and the image data of the document read in step S477 are compared (step S479).

If they are different, the process proceeds to step S491. If both are the same, the process proceeds to step S481.

In step 481, a preview screen indicating that the image data of the document read in step S471 and the image data of the document read in step S477 are the same, and a user interface screen used for allowing the user to select a corresponding method. Is displayed.

If there is an input for selecting to proceed to the next user interface screen displayed in step S481, the process proceeds to step S481. Thereby, for example, it is possible to cope with the case where the use is originally intended to print the same original on both sides.

If there is an input other than the input for selecting to proceed to the next user interface screen displayed in step S481, the process proceeds to step S483.

If there is an input for selecting a setting change as a corresponding method (pressing the button of "setting change" 331 on the screen 321) with respect to the user interface screen displayed in step 481, the process returns to step S461. After returning to step S461, setting the paper size (step S461), setting the orientation of the paper (step S463), setting the function (single-sided / single-sided printing, single-sided / double-sided printing, etc.) (step S465), reading the original. (Steps S471, S477, etc.) are executed again, and the process proceeds to step S479. For example, if the user originally intended single-sided / single-sided copying, single-sided / single-sided printing is set in step S465. In this case, the result becomes NO in step S466, and the process proceeds to another process. Further, for example, if the user also intends to perform single-sided / double-sided copying and wants to change the paper size or the paper direction, single-sided / double-sided printing is set in step S465. In this case, the result is YES in step S466, and the process proceeds to step S467.

If there is an input (pressing the "return" 325 button on the screen 321) for selecting all reloading as a corresponding method for the user interface screen displayed in step 481, the process returns to step S467. After returning to step S467, steps S467 to S477 are executed to read the two originals again. For example, if there is an error in the first set of originals, or if there is an error in the first set of two originals, it can be dealt with.

If there is an input for selecting reloading of only the second sheet as a corresponding method for the user interface screen displayed in step 481 (pressing the button of "redo the second sheet" 329 on the screen 321), step S485 Proceed to. If the process proceeds to step S485, the second document is read again by executing steps S485 to S489 similar to steps S473 to S477. For example, it is possible to deal with the case where there is an error in only the second original set first. From step S489, the process proceeds to step S491.

When the user presses the print start button in step S491, printing is executed (step S493).

If there is an input for selecting rereading of the original as a corresponding method for the user interface screen displayed in step 409, the process returns to step S405. After returning to step S405, the reading of the original (step S405) is executed again, and the process proceeds to step S407. For example, a document having the same size as the finished paper size set in step S401 is read in the same orientation as the orientation set in step S403 (step S405), and the process proceeds to step S407.

For the user interface screen displayed in step S409, select to proceed in the same manner as when the size and orientation of the finished paper set in steps S401 and S403 and the size and orientation of the document read in step S605 are the same. If there is an input for, the process proceeds to step S411.

In step S411, the user presses the print start button, and printing is executed in accordance with this (step S413).

The fifth embodiment is a specific example of the operation corresponding to the sixth embodiment.

The operation of the fifth embodiment is represented by a flowchart as shown in FIG. The operation of the fourth embodiment is represented by a flowchart as shown in FIG. 13, but both are substantially the same, in which step S466 is replaced by step S466B, step S481 is replaced by step S481B, and step S493 is replaced by step S493B. Are different, and the other steps are the same. Therefore, for similar steps, duplicate explanations will be omitted, and only the replaced steps will be described.

In step S466 of the fourth embodiment, it is determined whether or not the printing is single-sided / double-sided printing, but in step S466B of the fifth embodiment, it is determined whether or not the printing is double-sided / single-sided printing.

In step S483 of the fourth embodiment, the preview screen as shown in FIG. 3C is displayed, but in step S483B of the fifth embodiment, the preview screen as shown in FIG. 5C is displayed.

In step S493 of the fourth embodiment, single-sided / double-sided printing is performed, but in step S493B of the fifth embodiment, double-sided / single-sided printing is performed.

The sixth embodiment relates to a screen commonly used in each embodiment.

FIG. 14 shows the function currently selected for the document reading device after scanning the original in the single-sided printing copy or after scanning the original corresponding to the first side (front surface) in the double-sided printing copy. And in the settings, in order to let the user select the preview screen showing the abnormal reading result and the corresponding method, which is displayed when the document is read so that the reading result by the function cannot be obtained normally. It is a screen that combines the user interface screen used for.

As shown in FIG. 14, on the user interface screen, a "finish" button, a "return" button, a "restart the first sheet" button, a "change setting" button, and a "next" button are displayed.

The "Exit" button is for erasing the image data of the document read so far, returning the currently selected function and setting to the default one, and then returning to the initial screen.

The "Return" button is for erasing the image data of the document that has been read so far and maintaining the currently selected function and setting. After pressing the "Return" button, the user starts scanning again from the first document.

The "Redo 1st sheet" button is for erasing the image data of the original corresponding to the front surface in single-sided printing or double-sided printing in single-sided printing, and maintaining the currently selected function and setting. After pressing the "Redo 1st sheet" button, the user redoes the scanning from the first document corresponding to the front surface in single-sided printing or double-sided printing. For example, in the case where only two originals are read in the setting of four-sheet aggregation, it is possible to deal with the case where there are actually four originals to be read.

The "Change Settings" button is for changing the currently selected function and settings. When this is pressed, the image data of the document read so far is deleted, and the screen for changing the currently selected function and setting is displayed. After pressing the "Change Settings" button, the user changes the currently selected function and settings on the screen to another one, and starts scanning again from the first document. For example, in the case where only two originals are read in the setting of four-sheet aggregation, it is possible to deal with the case where the setting of two-sheet aggregation is actually intended.

The "Next" button is for proceeding to the next process as it is. For single-sided printing, proceed to printing, and for double-sided printing, proceed to read the back side.

FIG. 15 shows that after scanning a document corresponding to the second side (back side) in a copy for double-sided printing, the function and setting currently selected for the document reader can normally obtain a reading result by that function. This is a screen that combines a preview screen showing an abnormal reading result and a user interface screen used for allowing the user to select a corresponding method, which is displayed when the document is read so that the document cannot be read.

As shown in FIG. 15, on the user interface screen, a "finish" button, a "return" button, a "second redo" button, a "change setting" button, and a "next" button are displayed.

The "Exit" button is for erasing the image data of the document read so far, returning the currently selected function and setting to the default one, and then returning to the initial screen.

The "Return" button is for erasing the image data of the document that has been read so far and maintaining the currently selected function and setting. After pressing the "Return" button, the user restarts the reading from the first original (that is, the first original corresponding to the front surface).

The "Redo 2nd sheet" button keeps the image data of the original that corresponds to the front side in double-sided printing, but erases the image data of the original that corresponds to the back side and keeps the currently selected function and setting. It is a thing. After pressing the "Redo 2nd sheet" button, the user restarts scanning from the first original document corresponding to the back side in double-sided printing. For example, it is possible to deal with the case where the orientation of the first original is correct but the orientation of the second original is incorrect. In addition, in double-sided printing with 4 sheets on each side, 4 originals were read on the front side, but 4 originals were originally intended to be aggregated on the back side, but due to a user error, 4 It can be used when reading less than one document. Further, in single-sided / double-sided copying, it is possible to deal with a case where two different originals were originally intended to be copied, but the same original is read twice in succession due to a user's error.

The "Change Settings" button is for changing the currently selected function and settings. When this is pressed, the image data of the document read so far is deleted, and the screen for changing the currently selected function and setting is displayed. After pressing the "Change Settings" button, the user changes the currently selected function and setting on the screen to another one, and reads from the first document (that is, the first document corresponding to the surface). Redo.

The "Next" button is for proceeding to the next process, printing, as it is.
