[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-231887 Summary of the Invention [Problem to be solved by the invention]

[0004] In such an image reading device, a user sets the reading side of a document. When single-sided is set as the reading side, the image reading device reads one side of the document. When double-sided is set as the reading side, the image reading device reads both sides of the document. When a document set on the document table and a document set in the supply tray are read consecutively, a user may want to change the reading side midway. For example, when a document set on the document table is read and then a document set in the supply tray is read, the user may want to change the reading side from single-sided to double-sided. If the reading side cannot be changed midway, there is a risk that one side of the document set in the supply tray will remain set as the reading side. [Means for solving the problem]

[0005] An image reading device that solves the above problem comprises a document tray on which a document is set, a supply tray on which the document is set, a transport unit that transports the document set on the supply tray, a reading unit that reads the document set on the document tray and the document transported from the supply tray, a display unit that displays a continuation screen that asks whether the document should be read continuously when reading of the document is completed, and a control unit, wherein the control unit displays a change button on the continuation screen that changes the side of the document that is read by the reading unit.

[0006] A control method for an image reading device that solves the above problem is a control method for an image reading device that includes a document tray on which a document is set, a supply tray on which the document is set, a transport unit that transports the document set on the supply tray, a reading unit that reads the document set on the document tray and the document transported from the supply tray, and a display unit that displays a continuation screen that asks whether to continue reading the document when reading of the document is completed, and includes displaying a change button on the continuation screen that changes the reading side of the document by the reading unit, and changing the reading side of the document by the reading unit by operating the change button.

[0015] The transport unit 19 has one or more rollers. The transport unit 19 has, for example, a pick roller 20. The pick roller 20 transports the documents M1 set in the supply tray 18 one by one. In one example, the pick roller 20 comes into contact with the uppermost document M1 among the multiple documents M1 stacked on the supply tray 18. The transport unit 19 has one or more transport rollers 21. In one example, the transport unit 19 has a plurality of transport rollers 21. The multiple transport rollers 21 are positioned along the transport path 17.

[0016] The automatic sheet feeder 15 has a discharge tray 22. The discharge tray 22 is configured to receive the original M1 discharged from the base body 16. The discharge tray 22 is attached to the base body 16. The discharge tray 22 extends from the base body 16. The discharge tray 22 receives the read original M1.

[0017] The automatic sheet feeder 15 has a detection unit 23. The detection unit 23 is configured to detect the document M1 set on the supply tray 18. The detection unit 23 detects whether or not the document M1 is set on the supply tray 18. The detection unit 23 is, for example, an optical sensor.

[0018] The image reading device 11 includes a reading unit 24. The reading unit 24 is configured to read an original M1. The reading unit 24 reads an original M1 set on the platen 12 and an original M1 transported from the supply tray 18. The reading unit 24 is configured to be able to read the front and back sides of the original M1. The reading unit 24 is made up of a contact image sensor module. The reading unit 24 generates image data by reading the original M1.

[0019] The reading unit 24 has a first reading module 25 and a second reading module 26. The first reading module 25 is configured to read the front side of the document M1. The second reading module 26 is configured to read the back side of the document M1.

[0020] The first reading module 25 is attached to the platen 12. The first reading module 25 is located inside the housing 13. The first reading module 25 is configured to scan inside the housing 13. The first reading module 25 reads the original M1 through the transparent plate 14.

[0021] The first reading module 25 reads the original M1 set on the platen 12. The first reading module 25 reads the original M1 placed on the transparent plate 14 through the transparent plate 14. The first reading module 25 scans the original M1 set on the platen 12 to read the original M1.

[0022] The first reading module 25 reads the original M1 being transported on the transport path 17. The first reading module 25 reads the original M1 being transported on the transport path 17 through the transparent plate 14. That is, the first reading module 25 reads the original M1 set on the supply tray 18. At this time, the first reading module 25 does not scan the original M1.

[0023] The second reading module 26 is attached to the automatic sheet feeder 15. The second reading module 26 is located inside the base body 16. The second reading module 26 is located at a position along the transport path 17. The second reading module 26 reads the original M1 transported along the transport path 17. In other words, the second reading module 26 reads the original M1 set in the supply tray 18.

[0024] When reading the original M1 set on the platen 12, the first reading module 25 of the reading unit 24 functions. When reading the original M1 set on the supply tray 18, at least the first reading module 25 of the reading unit 24 functions. That is, when reading the original M1 set on the supply tray 18, the first reading module 25 of the reading unit 24 functions, or the first reading module 25 and the second reading module 26 function. When reading one side of the original M1, the first reading module 25 functions. When reading both sides of the original M1, the first reading module 25 and the second reading module 26 function.

[0025] The image reading device 11 includes a display unit 27. The display unit 27 is configured to display a screen. More specifically, the display unit 27 displays a screen for operating the image reading device 11. A user gives instructions to the image reading device 11 through the screen displayed on the display unit 27. The display unit 27 is, for example, a liquid crystal display. The display unit 27 is attached to the document table 12, for example. The display unit 27 notifies the user of information related to the image reading device 11 by displaying the screen.

[0026] The image reading device 11 includes an operation unit 28. The operation unit 28 is operated by a user. The user operates the image reading device 11 through the operation unit 28. The operation unit 28 is, for example, a touch panel. The operation unit 28 is not limited to a touch panel, and may also be a button, a lever, or the like.

[0027] The image reading device 11 includes a control unit 29. The control unit 29 is configured to control the image reading device 11. The control unit 29 controls the transport unit 19. The control unit 29 controls the reading unit 24. The control unit 29 controls the display unit 27. The control unit 29 causes the display unit 27 to display a screen. The control unit 29 executes instructions input via the screen displayed on the display unit 27.

[0028] The control unit 29 may be configured with one or more processors that execute various processes according to a computer program. The control unit 29 may be configured with one or more dedicated hardware circuits, such as an ASIC, that execute at least some of the various processes. The control unit 29 may be configured with a circuit that includes a combination of a processor and a hardware circuit. The processor includes a CPU and memory, such as RAM and ROM. The memory stores program code or instructions configured to cause the CPU to execute processes. The memory, i.e., computer-readable medium, includes any readable medium that can be accessed by a general-purpose or dedicated computer.

[0029] The control unit 29 starts reading the original M1 based on an instruction from the user. The control unit 29 starts reading the original M1 based on an instruction input through the operation unit 28. The control unit 29 starts reading the original M1 set on the platen 12 or starts reading the original M1 set in the supply tray 18 based on an instruction from the user.

[0030] The control unit 29 may determine whether to read the original M1 from the FB or from the ADF based on a user instruction, or may automatically determine this. FB is a flatbed. That is, FB refers to the platen 12. ADF is an automatic document feeder. That is, ADF refers to the automatic document feeder 15. For example, the control unit 29 is configured to read the original M1 from the ADF when the original M1 is set in the supply tray 18. That is, in one example, the control unit 29 is configured to prioritize reading the original M1 from the ADF.

[0031] The control unit 29 reads the original M1 based on the setting of the reading side. When the reading side is set to one side, the control unit 29 controls the reading unit 24 to read one side of the original M1. When the reading side is set to one side, the control unit 29 causes the first reading module 25 to function. When the reading side is set to both sides, the control unit 29 controls the reading unit 24 to read both sides of the original M1. When the reading side is set to both sides, the control unit 29 causes the first reading module 25 and the second reading module 26 to function.

[0032] The control unit 29 is configured to be able to continuously read the document M1. The control unit 29 is configured to be able to continuously read the document M1 from the FB and from the ADF. By continuously reading the document M1, the control unit 29 outputs the image data of the document M1 set on the document table 12 and the image data of the document M1 set in the supply tray 18 together as a single file. The control unit 29 outputs the image data from the FB and the image data from the ADF together as a PDF file or a TIFF file. For example, the user may have the document M1 set on the document table 12 read, and then set the document M1 on the supply tray 18, thereby continuously reading the document M1 set in the supply tray 18. This allows the user to, for example, combine a booklet image of a passport and a single sheet image of a sheet into a single file.

[0033] The control unit 29 may continuously read the document M1 from the FB and read another document M1 from the FB. In this case, the control unit 29 outputs the image data of the document M1 set on the document table 12 and the image data of the other document M1 set on the document table 12 together as one file.

[0034] The control unit 29 may continuously read one document M1 from the ADF and another document M1 from the ADF. In this case, the control unit 29 outputs the image data of the document M1 set on the supply tray 18 and the image data of the other document M1 set on the supply tray 18 together as a single file.

[0035] <Screen> Next, the screen displayed on the display unit 27 will be described. 2, when reading starts, a confirmation screen 30 is displayed. For example, when the user operates a read button on the home screen displayed on the display unit 27 to cause the image reading device 11 to read the document M1, the confirmation screen 30 is displayed.

[0036] The confirmation screen 30 is a screen that inquires whether to change the reading side. More specifically, the confirmation screen 30 is a screen that inquires whether to change the reading side when continuing reading. In one example, the confirmation screen 30 is a screen that confirms the setting of the reading side. For example, the confirmation screen 30 displays a message inquiring whether it is OK to set one side as the reading side for FB and both sides as the reading side for ADF.

[0037] The confirmation screen 30 displays a YES button 31 and a NO button 32. When the YES button 31 is operated, reading of the original M1 is started with the setting that one side is the reading surface for the FB and the setting that both sides are the reading surfaces for the ADF. When the YES button 31 is operated, the control unit 29 accepts that the reading surface will not be changed during continued reading. When the YES button 31 is operated, reading of the original M1 is started in a state where the reading surface setting cannot be changed during continued reading. When the NO button 32 is operated, the display of the confirmation screen 30 is switched.

[0038] 3, when the NO button 32 is operated on the confirmation screen 30, the display of the confirmation screen 30 changes. When the NO button 32 is operated, for example, a message prompting the user to set the reading surface for the ADF is displayed on the confirmation screen 30.

[0039] The confirmation screen 30 displays a single-sided button 33. The single-sided button 33 is a button for setting one side as the reading side. When the single-sided button 33 is operated, one side is set as the reading side for the ADF. When the single-sided button 33 is operated, reading of the original M1 is started with the reading side set to one side for the FB and the reading side set to one side for the ADF. When the single-sided button 33 is operated, the control unit 29 accepts that the reading side will not be changed during continued reading. When the single-sided button 33 is operated, reading of the original M1 is started in a state where the reading side setting cannot be changed during continued reading.

[0040] The confirmation screen 30 displays a double-sided button 34. The double-sided button 34 is a button that sets double-sided as the reading surface. When the double-sided button 34 is operated, the reading surface for the ADF is set to double-sided. When the double-sided button 34 is operated, reading of the original M1 is started with the reading surface set to single-sided for the FB and double-sided for the ADF. When the double-sided button 34 is operated, the control unit 29 accepts that the reading surface will not be changed during continued reading. When the double-sided button 34 is operated, reading of the original M1 is started in a state where the reading surface setting cannot be changed during continued reading.

[0041] The confirmation screen 30 displays a single-sided / double-sided mixed button 35. The single-sided / double-sided mixed button 35 indicates that the reading side will be changed during continued scanning. When the single-sided / double-sided mixed button 35 is operated, the control unit 29 accepts that the reading side will be changed during continued scanning. When the single-sided / double-sided mixed button 35 is operated, scanning of the original M1 is started in a state in which the reading side setting can be changed during continued scanning. After the single-sided / double-sided mixed button 35 is operated, if the original M1 is to be read from the ADF, a screen prompting the user to set the reading side for the ADF may be displayed. In this case, the image reading device 11 reads the original M1 from the ADF in accordance with the reading side setting. Typically, the user first reads the original M1 from the FB, and then reads the original M1 from the ADF.

[0042] As shown in FIG. 4, when reading of document M1 is completed, a continuation screen is displayed. For example, when reading of document M1 is completed, a first continuation screen 36 may be displayed. The continuation screen is a screen that inquires whether to continue reading document M1. In other words, the continuation screen is a screen that inquires whether to combine the image data that has been read so far and the image data to be read next into one file. When the control unit 29 accepts on the continuation screen that the document M1 will be read continuously, it starts the next reading. When the control unit 29 accepts on the continuation screen that the document M1 will not be read continuously, it outputs the image data that has been read so far as a file.

[0043] An end button 37 is displayed on the first continuous screen 36. When the end button 37 is operated, the first continuous screen 36 closes. When the end button 37 is operated, the control unit 29 accepts that the document M1 will not be read continuously. When the end button 37 is operated, the control unit 29 outputs the image data that has been read so far as a file.

[0044] A start button 38 is displayed on the first continuation screen 36. When the start button 38 is operated, reading of the original M1 starts. That is, the control unit 29 starts continuous reading. The continuation screen displays a change button 39. The change button 39 is a button for changing the reading side. The user changes the reading side by operating the change button 39 on the continuation screen.

[0045] The change button 39 may be displayed on the continuation screen when the control unit 29 has accepted that the reading side will be changed on the confirmation screen 30. In other words, the change button 39 does not need to be displayed on the continuation screen when the control unit 29 has accepted that the reading side will not be changed on the confirmation screen 30. In this case, the inconvenience is reduced for a user who does not plan to change the reading side during continued reading.

[0046] A single-sided icon 40 and a double-sided icon 41 are displayed on the first continuous screen 36. The single-sided icon 40 and the double-sided icon 41 are examples of the change button 39. On the first continuous screen 36, the change button 39 includes the single-sided icon 40 and the double-sided icon 41. When the single-sided icon 40 is operated, the reading side is set to single-sided. When the double-sided icon 41 is operated, the reading side is set to double-sided. In more detail, when the single-sided icon 40 is operated, the reading side for the ADF is set to single-sided. When the double-sided icon 41 is operated, the reading side for the ADF is set to double-sided.

[0047] The single-sided icon 40 indicates that the reading side is set to single-sided. The double-sided icon 41 indicates that the reading side is set to double-sided. The single-sided icon 40 and the double-sided icon 41 are highlighted according to the setting of the reading side. In the example shown in FIG. 4, the reading side is set to single-sided. The single-sided icon 40 is displayed more highlighted than the double-sided icon 41 when the reading side is set to single-sided. The double-sided icon 41 is displayed more highlighted than the single-sided icon 40 when the reading side is set to double-sided.

[0048] 5, when reading of the original M1 is completed, a second continuation screen 42 may be displayed. Similar to the first continuation screen 36, the second continuation screen 42 displays an end button 37 and a start button 38.

[0049] A transition button 43 is displayed on the second continuous screen 42. The transition button 43 is an example of the change button 39. When the transition button 43 is operated, the screen transitions to a screen where the reading side can be changed.

[0050] 6, when the transition button 43 is operated, a change screen 44 is displayed. The change screen 44 is a screen for changing the reading side. The change screen 44 displays a message prompting the user to set the reading side for the ADF.

[0051] The single-sided button 33 is displayed on the change screen 44. When the single-sided button 33 is operated, the reading side is set to single-sided. When the single-sided button 33 is operated, the change screen 44 returns to the second continuation screen 42.

[0052] The double-sided button 34 is displayed on the change screen 44. When the double-sided button 34 is operated, the reading side is set to double-sided. When the double-sided button 34 is operated, the change screen 44 returns to the second continuation screen 42.

[0053] 7 and 8, when the reading of the original M1 is completed, a third continuation screen 45 may be displayed. Similar to the first continuation screen 36, the third continuation screen 45 displays an end button 37.

[0054] The third continuous screen 45 displays a single-sided button 33 and a double-sided button 34. In the third continuous screen 45, the single-sided button 33 and the double-sided button 34 are examples of change buttons 39. In the third continuous screen 45, the change buttons 39 include the single-sided button 33 and the double-sided button 34. When the single-sided button 33 is operated, the reading side is set to single-sided. When the double-sided button 34 is operated, the reading side is set to double-sided. When the single-sided button 33 or the double-sided button 34 is operated, the reading side for the ADF is changed.

[0055] On the third continuous screen 45, the double-sided button 34 is enabled when the document M1 is set in the supply tray 18. That is, when the detection unit 23 detects the document M1, operation of the double-sided button 34 is enabled on the third continuous screen 45. For example, when the document M1 is not set in the supply tray 18, the double-sided button 34 is displayed in a less prominent manner than the single-sided button 33, as shown in FIG. 7. When the document M1 is set in the supply tray 18, the double-sided button 34 is displayed as shown in FIG. 8. When the invalid double-sided button 34 is operated, a message notifying that the operation is invalid may be displayed on the third continuous screen 45.

[0056] 9, when the single-sided button 33 or the double-sided button 34 is operated on the third continuation screen 45, a standby screen 46 is displayed. The standby screen 46 is a screen for waiting for the start of reading of the original M1. A start button 38 is displayed on the standby screen 46.

[0057] 10, when the reading of the original M1 is completed, a fourth continuation screen 47 may be displayed. The fourth continuation screen 47 displays the end button 37, similar to the first continuation screen 36. The fourth continuation screen 47 displays buttons for changing the reading side and starting reading of the original M1. Therefore, on the fourth continuation screen 47, it is possible to change the reading side and start reading of the original M1 with a single button.

[0058] A first button 48, a second button 49, and a third button 50 are displayed on the fourth continuation screen 47. The first button 48, the second button 49, and the third button 50 are examples of the change button 39. On the fourth continuation screen 47, the change button 39 includes the first button 48, the second button 49, and the third button 50. The first button 48, the second button 49, and the third button 50 are buttons for changing the reading side and starting reading of the document M1.

[0059] The first button 48 is a button that sets the reading side to single-sided and starts reading of the document M1 transported from the supply tray 18. When the first button 48 is operated, the reading side is set to single-sided and reading of the document M1 by the ADF is started. The second button 49 is a button that sets the reading side to double-sided and starts reading of the document M1 transported from the supply tray 18. When the second button 49 is operated, the reading side is set to double-sided and reading of the document M1 by the ADF is started. The third button 50 is a button that sets the reading side to single-sided and starts reading of the document M1 set on the platen 12. When the third button 50 is operated, the reading side is set to single-sided and reading of the document M1 by the FB is started.

[0060] <Flowchart> Next, the operation of the image reading device 11 will be described. First, the operation at the start of reading the original M1 will be described with reference to Fig. 11. The flowchart shown in Fig. 11 starts when the user gives an instruction to start reading to the image reading device 11. For example, the control unit 29 starts the flowchart by receiving an instruction to start reading from the user via the home screen.

[0061] As shown in FIG. 11, the control unit 29 displays a confirmation screen 30 in step S11. In step S12, the control unit 29 determines whether the reading surface is fixed. More specifically, the control unit 29 determines whether the YES button 31 has been operated on the confirmation screen 30. If the reading surface is fixed, that is, if the YES button 31 has been operated on the confirmation screen 30, the control unit 29 proceeds to step S15. If the reading surface is not fixed, that is, if the NO button 32 has been operated on the confirmation screen 30, the control unit 29 proceeds to step S13.

[0062] In step S13, the control unit 29 switches the confirmation screen 30. At this time, the confirmation screen 30 displays a single-sided button 33, a double-sided button 34, and a single-sided / double-sided mixed button 35.

[0063] In step S14, the control unit 29 determines whether to change the reading side during continued reading. More specifically, the control unit 29 determines whether the single-sided / double-sided mixed button 35 has been operated on the confirmation screen 30. If the reading side is to be changed during continued reading, that is, if the single-sided / double-sided mixed button 35 has been operated, the control unit 29 proceeds to step S16. If the reading side is not to be changed during continued reading, that is, if the single-sided button 33 or double-sided button 34 has been operated, the control unit 29 proceeds to step S15. If the single-sided button 33 has been operated, the control unit 29 sets the reading side for the ADF to single-sided. If the double-sided button 34 has been operated, the control unit 29 sets the reading side for the ADF to double-sided.

[0064] In step S15, the control unit 29 sets the reading side during continued reading to be unchangeable. That is, the control unit 29 controls the display unit 27 so that the change button 39 is not displayed on the continued screen.

[0065] In step S16, the control unit 29 determines whether or not there is a document M1 in the ADF. That is, the control unit 29 determines whether or not the detection unit 23 detects the document M1. If there is a document M1 in the ADF, that is, if the detection unit 23 detects the document M1, the control unit 29 proceeds to step S17. If there is no document M1 in the ADF, that is, if the detection unit 23 does not detect the document M1, the control unit 29 proceeds to step S18.

[0066] In step S17, the control unit 29 starts reading the original M1 from the ADF. At this time, the control unit 29 causes a screen for setting the reading surface for the ADF to be displayed on the display unit 27. For example, the control unit 29 may cause a change screen 44 to be displayed.

[0067] In step S18, the control unit 29 starts reading the document M1 from FB. Next, the operation when reading of document M1 is completed will be described with reference to Figs. 12 to 15. The flowcharts shown in Figs. 12 to 15 start when reading of document M1 is completed. The flowchart shown in Fig. 12 is a flowchart when the first continuation screen 36 is displayed. The flowchart shown in Fig. 13 is a flowchart when the second continuation screen 42 is displayed. The flowchart shown in Fig. 14 is a flowchart when the third continuation screen 45 is displayed. The flowchart shown in Fig. 15 is a flowchart when the fourth continuation screen 47 is displayed. The flowcharts shown in Figs. 12 to 15 show the operation when the control unit 29 accepts a request to change the reading side during continuous reading.

[0068] As shown in FIG. 12, the control unit 29 displays the first continuous screen 36 in step S21. In step S22, the control unit 29 determines whether to end the reading of the original M1. More specifically, the control unit 29 determines whether the end button 37 has been operated on the first continuation screen 36. At this time, the control unit 29 determines whether to continue reading the original M1. If the reading of the original M1 is to be ended, that is, if the end button 37 has been operated, the control unit 29 outputs the image data that has been read so far as a single file and ends the process. If the reading of the original M1 is not to be ended, that is, if the end button 37 has not been operated, the control unit 29 proceeds to step S23.

[0069] In step S23, the control unit 29 determines whether the change button 39 has been operated. More specifically, the control unit 29 determines whether the single-sided icon 40 or the double-sided icon 41 has been operated. If the change button 39 has been operated, i.e., if the single-sided icon 40 or the double-sided icon 41 has been operated, the control unit 29 proceeds to step S24. If the change button 39 has not been operated, i.e., if the single-sided icon 40 or the double-sided icon 41 has not been operated, the control unit 29 proceeds to step S26.

[0070] In step S24, the control unit 29 changes the reading side. More specifically, the control unit 29 sets the reading side according to the icon operated in step S23. If the single-sided icon 40 is operated in step S23, the control unit 29 sets the reading side for the ADF to single-sided. If the double-sided icon 41 is operated in step S23, the control unit 29 sets the reading side for the ADF to double-sided.

[0071] In step S25, the control unit 29 highlights the icon corresponding to the set reading side. If the reading side is set to single-sided in step S24, the control unit 29 highlights the single-sided icon 40. If the reading side is set to double-sided in step S24, the control unit 29 highlights the double-sided icon 41.

[0072] In step S26, the control unit 29 determines whether to start reading the document M1. More specifically, the control unit 29 determines whether the start button 38 has been operated on the first continuation screen 36. If the reading of the document M1 is to be started, that is, if the start button 38 has been operated, the control unit 29 proceeds to step S27. If the reading of the document M1 is not to be started, that is, if the start button 38 has not been operated, the control unit 29 returns the process to step S22.

[0073] In step S27, the control unit 29 determines whether or not there is a document M1 in the ADF. More specifically, the control unit 29 determines whether or not the detection unit 23 detects the document M1. If there is a document M1 in the ADF, that is, if the detection unit 23 detects the document M1, the control unit 29 proceeds to step S28. If there is no document M1 in the ADF, that is, if the detection unit 23 does not detect the document M1, the control unit 29 proceeds to step S29.

[0074] In step S28, the control unit 29 starts reading the document M1 from the ADF. That is, the document M1 is continuously read. In step S29, the control unit 29 starts reading the original M1 from FB. That is, the original M1 is read continuously.

[0075] As shown in FIG. 13, the control unit 29 displays the second continuous screen 42 in step S31. In step S32, the control unit 29 determines whether to end the reading of the original M1. More specifically, the control unit 29 determines whether the end button 37 has been operated on the second continuation screen 42. At this time, the control unit 29 determines whether to continue reading the original M1. If the reading of the original M1 is to be ended, that is, if the end button 37 has been operated, the control unit 29 outputs the image data that has been read so far as a single file and ends the process. If the reading of the original M1 is not to be ended, that is, if the end button 37 has not been operated, the control unit 29 proceeds to step S33.

[0076] In step S33, the control unit 29 determines whether the change button 39 has been operated. More specifically, the control unit 29 determines whether the transition button 43 has been operated. If the change button 39 has been operated, i.e., if the transition button 43 has been operated, the control unit 29 proceeds to step S34. If the change button 39 has not been operated, i.e., if the transition button 43 has not been operated, the control unit 29 proceeds to step S39.

[0077] In step S34, the control unit 29 displays the change screen 44. In step S35, the control unit 29 determines whether the single-sided button 33 has been operated. If the single-sided button 33 has been operated, the control unit 29 proceeds to step S36. If the single-sided button 33 has not been operated, the control unit 29 proceeds to step S37.

[0078] In step S36, the control unit 29 sets the reading surface of the ADF to one side. After setting the reading surface to one side, the control unit 29 causes the second continuous screen 42 to be displayed again. In step S37, the control unit 29 determines whether the double-sided button 34 has been operated. If the double-sided button 34 has been operated, the control unit 29 proceeds to step S38. If the double-sided button 34 has not been operated, the control unit 29 proceeds to step S39.

[0079] In step S38, the control unit 29 sets the reading surface of the ADF to "double-sided." After setting the reading surface to "double-sided," the control unit 29 causes the second continuous screen 42 to be displayed again. In step S39, the control unit 29 determines whether to start reading the document M1. More specifically, the control unit 29 determines whether the start button 38 has been operated on the second continuation screen 42. If the reading of the document M1 is to be started, that is, if the start button 38 has been operated, the control unit 29 proceeds to step S40. If the reading of the document M1 is not to be started, that is, if the start button 38 has not been operated, the control unit 29 returns the process to step S32.

[0080] In step S40, the control unit 29 determines whether or not there is a document M1 in the ADF. More specifically, the control unit 29 determines whether or not the detection unit 23 detects the document M1. If there is a document M1 in the ADF, that is, if the detection unit 23 detects the document M1, the control unit 29 proceeds to step S41. If there is no document M1 in the ADF, that is, if the detection unit 23 does not detect the document M1, the control unit 29 proceeds to step S42.

[0081] In step S41, the control unit 29 starts reading the document M1 from the ADF. That is, the document M1 is continuously read. In step S42, the control unit 29 starts reading the original M1 from FB, that is, the original M1 is read continuously.

[0082] As shown in FIG. 14, the control unit 29 displays a third continuous screen 45 in step S51. In step S52, the control unit 29 determines whether to end the reading of the original M1. More specifically, the control unit 29 determines whether the end button 37 has been operated on the third continuation screen 45. At this time, the control unit 29 determines whether to continue reading the original M1. If the reading of the original M1 is to be ended, that is, if the end button 37 has been operated, the control unit 29 outputs the image data that has been read so far as a single file and ends the process. If the reading of the original M1 is not to be ended, that is, if the end button 37 has not been operated, the control unit 29 proceeds to step S53.

[0083] In step S53, the control unit 29 determines whether or not there is a document M1 in the ADF. More specifically, the control unit 29 determines whether or not the detection unit 23 detects the document M1. If there is a document M1 in the ADF, that is, if the detection unit 23 detects the document M1, the control unit 29 proceeds to step S54. If there is no document M1 in the ADF, that is, if the detection unit 23 does not detect the document M1, the control unit 29 proceeds to step S55.

[0084] In step S54, the control unit 29 enables the double-sided button 34. At this time, the control unit 29 displays the double-sided button 34 on the third continuous screen 45 so that it can be operated. In step S55, the control unit 29 determines whether the change button 39 has been operated. More specifically, the control unit 29 determines whether the single-sided button 33 or the double-sided button 34 has been operated. If the change button 39 has been operated, that is, if the single-sided button 33 or the double-sided button 34 has been operated, the control unit 29 returns the process to step S52.

[0085] In step S56, the control unit 29 changes the reading side. More specifically, the control unit 29 sets the reading side in accordance with the button operated in step S55. If the single-sided button 33 is operated in step S55, the control unit 29 sets the reading side for the ADF to single-sided. If the double-sided button 34 is operated in step S55, the control unit 29 sets the reading side for the ADF to double-sided.

[0086] In step S57, the control unit 29 displays the standby screen 46. In step S58, the control unit 29 determines whether to start reading the original M1. More specifically, the control unit 29 determines whether the start button 38 has been operated on the standby screen 46. If reading of the original M1 is to be started, that is, if the start button 38 has been operated, the control unit 29 proceeds to step S59. If reading of the original M1 is not to be started, that is, if the start button 38 has not been operated, the control unit 29 returns the process to step S58. If the start button 38 has not been operated, the control unit 29 repeats the process of step S58.

[0087] In step S59, the control unit 29 determines whether or not there is a document M1 in the ADF. More specifically, the control unit 29 determines whether or not the detection unit 23 detects the document M1. If there is a document M1 in the ADF, that is, if the detection unit 23 detects the document M1, the control unit 29 proceeds to step S60.

[0088] In step S60, the control unit 29 starts reading the document M1 from the ADF. That is, the document M1 is continuously read. In step S61, the control unit 29 starts reading the original M1 from FB. That is, the original M1 is read continuously.

[0089] As shown in FIG. 15, the control unit 29 displays the fourth continuation screen 47 in step S71. In step S72, the control unit 29 determines whether to end the reading of the original M1. More specifically, the control unit 29 determines whether the end button 37 has been operated on the fourth continuation screen 47. At this time, the control unit 29 determines whether to continue reading the original M1. If the reading of the original M1 is to be ended, that is, if the end button 37 has been operated, the control unit 29 outputs the image data that has been read so far as a single file and ends the process. If the reading of the original M1 is not to be ended, that is, if the end button 37 has not been operated, the control unit 29 proceeds to step S73.

[0090] In step S73, the control unit 29 determines whether the change button 39 has been operated. More specifically, the control unit 29 determines whether any of the first button 48, the second button 49, and the third button 50 has been operated. If the change button 39 has been operated, that is, if any of the first button 48, the second button 49, and the third button 50 has been operated, the control unit 29 proceeds to step S74. If the change button 39 has not been operated, that is, if any of the first button 48, the second button 49, and the third button 50 has not been operated, the control unit 29 repeats the processing of step S74.

[0091] In step S74, the control unit 29 changes the reading side. More specifically, the control unit 29 sets the reading side in accordance with the button operated in step S73. If the first button 48 is operated in step S73, the control unit 29 sets the reading side to one side. If the second button 49 is operated in step S73, the control unit 29 sets the reading side to both sides. If the third button 50 is operated in step S73, the control unit 29 sets the reading side to one side.

[0092] The control unit 29 starts reading the document M1 in step S75.
