Description

  The present invention relates to an image processing apparatus that reads a document such as a multifunction peripheral or a copying machine and prints the document on a sheet.

  An original table of a copying machine or a multifunction machine is generally flat. When a book document having a binding portion is placed on a flat document table, the binding portion does not come into close contact with the document table and is lifted from the document table. For this reason, when a book document is read by a copying machine or the like having a flat document table, the image data of the binding portion is darker than it is actually or is reduced and recognized by the copying machine.

  Japanese Patent Application Laid-Open No. 2000-165617 discloses an image reading apparatus that can accurately read a binding portion. In the image reading apparatus 500 described in this publication, as shown in FIG. 10, the document table 101 is extended to the corner portion 111 of the image reading apparatus 500.

  When reading the book document 113 with the image reading apparatus 500, the user aligns the binding portion 114 of the book document 113 in a spread state with the corner portion 111, and selects the page to be read out of the even page 116 and the odd page 117. 101, and the other page is placed along the side surface 115.

Since the document table 101 is extended to the corner portion 111, the binding portion 114 can be brought into close contact with the document table 101. Therefore, the image reading apparatus 500 disclosed in the above publication can accurately read the binding portion 114.
JP 2000-165617 A

  When the book original 113 is read by the image reading apparatus 500 with the binding portion 114 aligned with the corner portion 111, as shown in FIG. 11, when the even page 116 is read and when the odd page 117 is read, the book The document 113 is placed on the image reading apparatus 500 with a direction different by 180 degrees.

  Therefore, when the book document 113 read by the image reading apparatus 500 is printed, the even page 116 and the odd page 117 are discharged in directions different by 180 degrees. It is the user's work to align the orientation.

  SUMMARY An advantage of some aspects of the invention is that it provides an image processing apparatus that can print even-numbered pages and odd-numbered pages with the same orientation in order to save the user's trouble.

  The image processing apparatus according to the present invention prints by rotating a document on either an even page or an odd page so that the even page and the odd page can be printed with the same orientation. . The rotation process here is to rotate the orientation of the image by 180 degrees.

  The following method is an example of a method for performing the rotation process.

  The first method is a method of rotating image data obtained by scanning a document by 180 degrees. Specifically, for example, when image data obtained by scanning is sequentially stored in a memory, the entire original is scanned, and the image data of the entire original is stored in the memory, the order is the reverse of the stored order. Image data is read from the memory, and a copy image is formed based on the read order.

  The second method is to change the scanning direction of the document. For example, the scanning direction of the document to be rotated and the scanning direction of the document not to be rotated are reversed. If the scanning direction is reversed, the order of image data obtained by scanning is different, so that a copy image can be formed on the basis of the obtained order of image data. Therefore, no memory is required.

  Moreover, you may perform a rotation process using both the 1st method and the 2nd method. For example, only the sub-scanning direction of scanning of a document to be rotated is reversed to the scanning direction of a document not to be rotated, and the position in the main scanning direction of image data obtained by scanning with the sub-scanning direction reversed is reversed. Then, rotation processing may be performed.

  Inversion of the position in the main scanning direction is performed, for example, when image data obtained by scanning is sequentially stored in the memory, and when image data of one main scanning line is stored in the memory, the order of the stored data is reversed. Then, the image data of one main scanning line is read out, and the read image data of one main scanning line is arranged based on the read order.

  When the position of the image data only in the main scanning direction is inverted every time image data of one main scanning line is stored, the capacity of the memory necessary for the inversion is the capacity of image data for one main scanning line. That's it.

  As described above, when printing either an even page or an odd page of an original, since the original is rotated and printed, images of the even page and the odd page are printed in the same direction. Therefore, it is possible to save the user's trouble of aligning the orientation of the image.

(Embodiment 1)
FIG. 1 is an external view of an image processing apparatus 100 according to the present embodiment. The image processing apparatus 100 includes a main body 107 provided with a display panel 105 and a document table 101 on an upper surface, and a platen cover 102 provided on the upper portion of the main body 107 so as to be opened and closed. The platen cover 102 is provided with an automatic document feeder 103 that conveys a plurality of documents one by one to the reading position 104. The document table 101 is extended to the corner portion 111 as shown in FIG.

  FIG. 2 is an enlarged cross-sectional view around the document table 101 of the image processing apparatus 100. As shown in FIG. 2, the image reading apparatus 100 includes a light source 11 that irradiates the document table 101, a reflecting plate 21 that guides light emitted from the light source 11 to the document table 101, and a document table. Mirrors 12, 13, and 14 for guiding the reflected light from 101 to the CCD 16, and a carriage 17 that supports the light source 11 and the mirror 12 and can move in the sub-scanning direction are provided. The carriage 17 stands by at the home position HP when the document is not scanned.

  When scanning a document placed on the document table 101, the scanning unit 404 provided in the image processing apparatus 100 shown in FIG. 3 moves the carriage 17 in the sub-scanning direction while causing the light source 11 to emit light. 101 is irradiated. When a document is placed on the document table 101, light emitted from the light source 11 is reflected by the document, guided to the mirrors 12, 13, and 14 and received by the CCD 16.

  The image processing apparatus 100 according to the present embodiment can copy an image of a document as it is, or can copy it by rotating it 180 degrees. The user can select which method is used for copying.

  On the initial screen of the display panel 105 of the image processing apparatus 100 of the present embodiment, as shown in FIG. 4A, a book original key 301, a print key 302, a magnification change key 303, a paper size change key 304, and the like. It is displayed. When it is desired to copy only the even page 116 or the odd page 117 of the document by rotating 180 degrees, the user presses the book document key 301.

  When the book original key 301 is pressed, the copy control means 401 shown in FIG. 3 provided in the image processing apparatus 100 activates the book original mode (S501 in FIG. 5). When the book manuscript mode is activated, the copy control unit 401 switches the display panel 105 from the initial screen to a screen displaying an OK key 305 and a cancel key 306 as shown in FIG.

  When the user presses the book original key 301, a page to be copied of the book original 113 is placed on the original table 101. The pages to be copied in this embodiment are two pages, an even page 116 in which the characters “ABC” shown in FIG. 6 are described and an odd page 117 in which “XYZ” is described. Here, it is assumed that the user performs copying in the order of odd-numbered pages 117 and even-numbered pages 116.

  To place the odd pages 117, as shown in FIG. 7A, the book original 113 in the state shown in FIG. 6 is turned upside down, the binding portion 114 is aligned with the corner portion 111, and the odd pages 117 are placed. Place it on the document table 101. Therefore, the lower left point A, the upper left point B, the upper right point C, and the lower right point D of the odd page 117 in the state shown in FIG. 6 are displayed on the document table 101 as shown in FIG. It is located in the upper left, lower left, lower right, and upper right.

  When the odd page 117 is placed on the document table 101 and the screen of the display panel 105 is switched to the screen shown in FIG. 4B, the user presses the OK key 305 (FIG. 5, S502). The determination unit 402 recognizes that the OK key 305 has been pressed.

  The determination unit 402 counts the number of times the OK key 305 is pressed to determine whether the document placed on the document table 101 is the even page 116 or the odd page 117, and the result is the copy control unit 401. (S503 in FIG. 5). In the present embodiment, the determination unit 402 determines that the number of times the OK key 305 has been pressed is an odd number, and determines that it is an odd page 117, and if the number is an even number, determines that the page is an even page 116.

  In the present embodiment, the OK key 305 has been pressed only once so far, so the determination unit 402 notifies the copy control unit 401 that the page is an odd page 117.

  Based on the result notified from the determination unit 402, the copy control unit 401 determines whether to copy the original image as it is or to rotate the image by 180 degrees (S504 in FIG. 5). In this embodiment, when the odd page 117 is notified, the copy control unit 401 determines to copy the original image as it is, and when the even page 116 is notified, the copy control unit 401 rotates 180 degrees and copies.

  As described above, since the odd page 117 is notified here, the copy control unit 401 determines to copy the original image as it is. When it is determined that the original image is copied as it is, the copy control unit 401 notifies the image processing unit 403 to that effect.

  When notified that the original image is to be copied as it is, the image processing means 403 instructs the scanning means 404 to scan the original table 101.

  When there is a scanning instruction, the scanning unit 404 detects the size of the document placed on the document table 101, calculates the position of the end portion of the document opposite to the corner portion 111, and calculates the calculated position. The determined position is determined as the reading start position Pa. When the reading start position Pa is determined, the scanning unit 404 moves the carriage 17 from the home position HP to the reading start position Pa. When the scanning unit 404 is moved to the reading start position Pa, the scanning unit 404 notifies the image processing unit 403 to start scanning, and the carriage 17 is moved from the reading start position Pa to the corner portion 111 while the light source 11 is turned on. Then, the original is scanned (FIG. 5, S505).

  The light received by the CCD 16 as described above is converted into an electrical signal indicating image data and input to the image processing means 403. The image processing means 403 considers that an electrical signal input before the start of scanning is notified is invalid as image data.

  As shown in FIG. 7A, the odd-numbered page 117 is placed on the document table 101 with the upper right point C and the lower right point D serving as the binding portion 114 set to the corner portion 111 side, and the carriage 17 is positioned at the reading start position. Since it moves from Pa to the corner portion 111, in this scanning, scanning is performed from the left side to the right side of the odd page 117 in FIG.

  The light source 11 is long in the main scanning direction, and a large number of CCDs 16 are arranged in the main scanning direction as shown in FIG. 7A so that the light emitted from the light source 11 can be received. . Here, the electrical signals converted by the CCDs 16 are outputted to the image processing means 403 in order from those converted by the CCDs 16 arranged on the upper side of FIG.

  Therefore, the order of the positions of the odd-numbered pages 117 where the image data is output to the image processing means 403 is as shown by the arrow direction 127 in FIG. 8, the lower left point A, the upper left point B, the lower right point D, and the upper right point. C order.

  Here, since the copy control means 401 is notified that the image of the document is copied as it is, the image processing means 403 outputs the image data input from each CCD 16 to the printing means 405 in the order of input. .

  The printing unit 405 forms copy data from the image data based on the input order, and prints the copy data (FIG. 5, S506).

  When the odd page 117 is printed, the user places the even page 116 on the document table 101. To place the even page 116, as shown in FIG. 7B, the book document 113 in the state of FIG. 6 is turned over in the left-right direction, the binding portion 114 is aligned with the corner portion 111, and the even page 116 is placed. Place it on the document table 101. Therefore, the lower left point A, the upper left point B, the upper right point C, and the lower right point D of the even page 116 in the state shown in FIG. 6 are displayed on the platen 101 on the right side of the even page 106 as shown in FIG. It will be located at the bottom, top right, top left and bottom left.

  When the even page 116 is placed on the document table 101, the user presses the OK key 305 (FIG. 5, S507). The determination unit 402 recognizes that the OK key 305 has been pressed.

  Since the OK key 305 is pressed for the second time, the determination unit 402 determines that the document placed on the document table 101 is the even page 116 and notifies the copy control unit 401 that the page is the even page 116. (S503 in FIG. 5).

  When notified that the page is an even page 116, the copy control unit 401 determines to rotate the image of the document by 180 degrees and copies it, and notifies the image processing unit 403 to that effect (S504 in FIG. 5). .

  When notified that the image of the original is to be rotated 180 degrees and copied, first, the image processing unit 403 scans the document table 101 in the same manner as when notified that the original is to be copied as it is. The scanning means 404 is instructed.

  When there is a scanning instruction, the scanning unit 404 determines the reading start position Pa in the same manner as described above, and moves the carriage 17 from the reading start position Pa to the corner portion 111 to scan the document (FIG. 5, FIG. 5). S508).

As shown in FIG. 7B, the even-numbered page 116 is placed on the document table 101 with the upper left point A and the lower left point B serving as the binding portion 114 facing the corner portion 111, and the carriage 17 is positioned at the reading start position. Since it moves from Pa to the corner portion 111, in this scanning, scanning is performed from the upper right point C and the lower right point D side of the even page 116 to the lower left point A and the upper left point B side. Further, as described above, in the present embodiment, the electrical signals converted into the CCDs 116 are output to the image processing unit 403 in order from those converted by the CCDs 116 arranged on the upper side of FIG. Therefore, the order of all positions of the even page 116 where the image data is output to the image processing means 403 is as shown by the arrow 126 in FIG. 8 at the upper right point C, the lower right point D, the upper left point. B and lower left point A in this order. This order is completely opposite to that of the odd page 117.

  Here, since the copying control means 401 is notified that the image of the document is to be rotated 180 degrees and copied, the image processing means 403 sends the image data output from each CCD 16 to the printing means 405 as it is. Instead of outputting, the data are temporarily stored in the memory 406 in the order of output from the CCD 16.

  When the image processing unit 403 stores the image data corresponding to each position of the even page 116 in the memory 406, the image processing unit 403 reads the data from the memory 406 in the reverse order of the stored order and inputs the read data to the printing unit 405 (FIG. 5, FIG. 5). S509). The printing unit 405 prints the copied image formed in the input order (FIG. 5, S506).

  The order of the positions of the even page 116 where the image data is input to the printing unit 405 is the lower left point A, the upper left point B, the lower right point D, and the upper right point C, and the image data of the odd page 117 is input to the printing unit 405. It will be the same as the input order. Therefore, the copy image of the even page 116 formed by the printing unit 405 has the same orientation as the copy image of the odd page 117.

  When the even page 116 is copied, the user presses the cancel key 306 of the display panel 105 (FIG. 5, S507). When the cancel key 306 is pressed, the determination unit 402 resets the number of times the OK key 305 is pressed to 0, and the copy control unit 401 ends the book original mode and brings the display panel 105 to the initial screen. return.

(Embodiment 2)
The method of rotating the image of the document by 180 degrees is not limited to the method of reading from the memory 406 in the reverse order to the image data storage order.

  For example, a method that utilizes a change in the scanning direction of scanning of a document may be used. In the present embodiment, a case will be described in which a change in the sub-scanning direction of the scanning direction is used to rotate the original image by 180 degrees.

  As in the first embodiment, when the copying control unit 401 notifies that the document image is to be rotated by 180 degrees, the image processing unit 403 instructs the scanning unit 404 in the sub-scanning direction. Indicates scanning in the reverse direction.

  When there is an instruction to scan in the reverse direction of the sub-scanning direction, the scanning unit 404 first detects the size of the document placed on the document table 101 and detects the size of the end of the document opposite to the corner portion 111. A position is calculated, and the calculated position is determined as a reading end position. When the reading end position is determined, the scanning unit 404 moves the carriage 17 to the corner portion 111 that becomes the reading start position Pa in the present embodiment. When the carriage 17 is moved to the corner portion 111, the scanning means 404 notifies the image processing means 403 of the start of scanning, and the carriage 17 is moved from the corner portion 111 to the reading end position while the light source 11 is turned on. Let

  Here, it is assumed that when the carriage 17 is moved from the corner portion 111 to the reading end position, the document on the even page 116 is placed on the document table 101 as shown in FIG.

  As shown in FIG. 7B, the even page 116 is placed on the document table 101 with the upper left point A and the lower left point B, which are the binding portions 114, facing the corner portion 111, and the carriage 17 extends from the corner portion 111. Since it moves to the reading end position, in this scanning, scanning is performed from the lower left point A and upper left point B side of the even page 116 to the upper right point C and lower right point D side.

  For this reason, the order of the positions of the even-numbered page 116 where the electrical signal serving as the image data is output to the image processing means 403 is as shown by the arrow 128 in FIG. 9, the upper left point B, the lower left point A, the upper right point C, The order is the lower right point D. This order is the same as the odd-numbered page 117 of the first embodiment in the sub-scanning direction, and only the main scanning direction is reversed.

  Similarly to the first embodiment, in the present embodiment, when the copy control means 401 notifies that the image of the document is rotated by 180 degrees and is copied, the image processing means 403 receives an input from each CCD 16. The image data thus stored is stored in the memory 406 in the order of input.

  Each time image data for one main scanning line is stored in the memory 406, the image processing unit 403 reads the image data from the memory 406 in the reverse order of the stored order and inputs the read image data to the printing unit 405.

  As a result, the order in which the image data is stored and the order in which they are read out are reversed in each main scanning line. Therefore, the order of the positions of the even pages 106 from which the image data is read from the memory 406 is the lower left point A, the upper left point B, the lower right point D, and the upper right point C. This order is the odd page 117 in the first embodiment. The order in which the image data is input to the printing unit 405 is the same.

  Therefore, the image processing means 403 inputs image data to the printing means 405 in the order read from the memory 406, so that a copy image of the even page 116 rotated 180 degrees is formed by the printing means 405. .

  In this embodiment, when the image data of one main scanning line is stored in the memory, the image data is read from the memory 406. Therefore, the capacity of the memory 406 can store the image data of one main scanning line. Capacity is enough.

  Further, as in the first embodiment, when the odd page 117 is scanned and the even page 116 is scanned, the scanning of one page is completed in order to move the carriage 17 from the reading start position Pa to the corner portion 111. Each time, the carriage 17 must be returned from the corner portion 111 to the reading start position. However, as in the present embodiment, when copying odd pages 117, the carriage 17 is moved from the reading start position Pa to the corner portion 111, and when copying even pages 116, the carriage is moved in the reverse direction. Therefore, when the scanning of one page is completed, the next page can be scanned only by moving the carriage 17 in the reverse direction from the spot.
