[0008] An embodiment of the image reading apparatus will be described below with reference to the drawings. <Image reader> 1, the image reading device 11 includes a document table 12. The document table 12 is configured so that a document M1 can be set thereon. The document M1 is placed on the document table 12, whereby the document M1 is set on the document table 12.

[0009] The document table 12 has a housing 13. The document table 12 has a transparent plate 14. The transparent plate 14 is attached to the housing 13. The transparent plate 14 forms a top plate of the housing 13. The document M1 is placed on the transparent plate 14 and set on the document table 12.

[0010] The image reading device 11 includes a cover 15. The cover 15 is attached to the document table 12. The cover 15 overlaps the document table 12. The cover 15 is configured to open and close relative to the document table 12. When the cover 15 is opened, the transparent plate 14 is exposed. When the cover 15 is opened, it becomes possible to set a document M1 on the document table 12. When the cover 15 is closed relative to the document table 12, it presses down on the document M1 set on the document table 12 from above. In the state shown in FIG. 1 , the cover 15 is closed relative to the document table 12. The document M1 is sandwiched between the document table 12 and the cover 15 and is read by the image reading device 11.

[0011] The image reading device 11 may include a cover detection unit 16. The cover detection unit 16 detects whether the cover 15 is open or closed relative to the platen 12. The cover detection unit 16 may detect that the cover 15 is open relative to the platen 12, or may detect that the cover 15 is closed relative to the platen 12. The cover detection unit 16 is attached to the housing 13, for example. The cover detection unit 16 may be attached to the cover 15. The cover detection unit 16 may be a contact sensor or an optical sensor. The cover detection unit 16 may detect that the cover 15 is closed relative to the platen 12 by coming into contact with the cover 15. The cover detection unit 16 may detect that the cover 15 is closed relative to the platen 12 by a decrease in the amount of detected light.

[0012] The image reading device 11 is equipped with an automatic paper feeder 17. The automatic paper feeder 17 is configured to automatically feed the original M1. The automatic paper feeder 17 is attached to the cover 15. The automatic paper feeder 17 feeds the original M1 into the cover 15. A transport path 18 is formed in the cover 15. That is, the cover 15 defines the transport path 18. The transport path 18 is a path along which the original M1 is transported. The transport path 18 extends inside the cover 15. The original M1 is read by the image reading device 11 while being transported along the transport path 18.

[0013] The automatic sheet feeder 17 has a supply tray 19. The supply tray 19 is attached to the cover 15. The supply tray 19 extends from the cover 15. The supply tray 19 is configured so that the document M1 can be set thereon. The document M1 is placed on the supply tray 19, whereby the document M1 is set in the supply tray 19.

[0014] The automatic sheet feeder 17 has a transport unit 20. The transport unit 20 is attached to the cover 15. The transport unit 20 is configured to transport the document M1. The transport unit 20 transports the document M1 set in the supply tray 19. The transport unit 20 transports the document M1 along the transport path 18.

[0015] The transport unit 20 has one or more rollers. The transport unit 20 has, for example, a pick roller 21. The pick roller 21 transports the documents M1 set on the supply tray 19 one by one. In one example, the pick roller 21 comes into contact with the uppermost document M1 among the multiple documents M1 stacked on the supply tray 19. The transport unit 20 has one or more transport rollers 22. In one example, the transport unit 20 has a plurality of transport rollers 22. The multiple transport rollers 22 are positioned along the transport path 18.

[0016] The automatic sheet feeder 17 has a discharge tray 23. The discharge tray 23 is configured to receive the document M1 discharged from the cover 15. The discharge tray 23 is attached to the cover 15. The discharge tray 23 extends from the cover 15. The discharge tray 23 receives the read document M1.

[0017] The automatic sheet feeder 17 has a detection unit 24. The detection unit 24 is configured to detect the document M1 set on the supply tray 19. The detection unit 24 detects whether or not the document M1 is set on the supply tray 19. The detection unit 24 may be a contact sensor or an optical sensor.

[0018] The automatic sheet feeder 17 may have a multi-feed detection unit 25. The multi-feed detection unit 25 is configured to detect multi-feeding of the original documents M1. That is, the multi-feed detection unit 25 detects whether multiple overlapping original documents M1 are being transported from the supply tray 19. The multi-feed detection unit 25 is attached to the cover 15. The multi-feed detection unit 25 is located along the transport path 18. The multi-feed detection unit 25 includes, for example, an ultrasonic sensor. The multi-feed detection unit 25 irradiates the original documents M1 with ultrasonic waves. The multi-feed detection unit 25 detects multi-feeding based on the attenuation rate of the ultrasonic waves. For example, when a multi-feed has occurred, the attenuation rate of the ultrasonic waves is greater than when a multi-feed has not occurred. This allows the multi-feed detection unit 25 to detect multi-feeding.

[0019] The image reading device 11 includes a reading unit 26. The reading unit 26 is configured to read an original M1. The reading unit 26 reads an original M1 set on the platen 12 and an original M1 transported from the supply tray 19. The reading unit 26 is configured to be able to read the front and back sides of the original M1. The reading unit 26 is made up of a contact image sensor module. The reading unit 26 generates image data by reading the original M1.

[0020] The reading unit 26 has a first reading module 27 and a second reading module 28. The first reading module 27 is configured to read the front side of the document M1. The second reading module 28 is configured to read the back side of the document M1.

[0021] The first reading module 27 is attached to the platen 12. The first reading module 27 is located inside the housing 13. The first reading module 27 is configured to scan inside the housing 13. The first reading module 27 reads the original M1 through the transparent plate 14.

[0022] The first reading module 27 reads the original M1 set on the platen 12. The first reading module 27 reads the original M1 placed on the transparent plate 14 through the transparent plate 14. The first reading module 27 scans the original M1 set on the platen 12 to read the original M1.

[0023] The first reading module 27 reads the original M1 being transported on the transport path 18. The first reading module 27 reads the original M1 being transported on the transport path 18 through the transparent plate 14. That is, the first reading module 27 reads the original M1 set on the supply tray 19. At this time, the first reading module 27 does not scan the original M1.

[0024] The second reading module 28 is attached to the cover 15. The second reading module 28 is located inside the cover 15. The second reading module 28 is located at a position along the conveying path 18. The second reading module 28 reads the original M1 being conveyed along the conveying path 18. In other words, the second reading module 28 reads the original M1 set on the supply tray 19.

[0025] When reading the original M1 set on the platen 12, the first reading module 27 of the reading unit 26 functions. When reading the original M1 set on the supply tray 19, at least the first reading module 27 of the reading unit 26 functions. That is, when reading the original M1 set on the supply tray 19, the first reading module 27 of the reading unit 26 functions, or the first reading module 27 and the second reading module 28 function. When reading one side of the original M1, the first reading module 27 functions. When reading both sides of the original M1, the first reading module 27 and the second reading module 28 function.

[0026] The image reading device 11 includes a display unit 29. The display unit 29 is configured to display a screen. More specifically, the display unit 29 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 29. The display unit 29 is, for example, a liquid crystal display. The display unit 29 is attached to the document table 12, for example. The display unit 29 notifies the user of information related to the image reading device 11 by displaying the screen.

[0027] The image reading device 11 includes an operation unit 30. The operation unit 30 is operated by a user. The user operates the image reading device 11 through the operation unit 30. The operation unit 30 is, for example, a touch panel. The operation unit 30 is not limited to a touch panel and may include buttons, levers, switches, etc.

[0028] The image reading device 11 includes a control unit 31. The control unit 31 is configured to control the image reading device 11. The control unit 31 controls the conveying unit 20. The control unit 31 controls the reading unit 26. The control unit 31 controls the display unit 29. The control unit 31 causes the display unit 29 to display a screen. The control unit 31 controls the image reading device 11 based on instructions input via the screen displayed on the display unit 29.

[0029] The control unit 31 may be configured with one or more processors that execute various processes according to a computer program. The control unit 31 may be configured with one or more dedicated hardware circuits, such as ASIC, that execute at least some of the various processes. The control unit 31 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 that are 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.

[0030] The control unit 31 starts reading the original M1 based on an instruction from the user. The control unit 31 starts reading the original M1 based on an instruction input through the operation unit 30. The control unit 31 starts reading the original M1 set on the platen 12 or starts reading the original M1 set in the supply tray 19 based on an instruction from the user.

[0031] The control unit 31 automatically determines the reading destination of the original M1. More specifically, the control unit 31 automatically determines whether to read the original M1 set on the platen 12 or the original M1 set on the supply tray 19. In one example, the control unit 31 is configured to read the original M1 set on the supply tray 19 when the original M1 is set on the supply tray 19. The control unit 31 is configured to read the original M1 set on the platen 12 when the original M1 is not set on the supply tray 19. In other words, the control unit 31 is configured to prioritize reading the original M1 set on the supply tray 19. The control unit 31 may determine the reading destination of the original M1 based on a user instruction.

[0032] Based on the detection result of the original M1, the control unit 31 determines whether to read the original M1 from the FB or from the ADF. 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 17.

[0033] The control unit 31 determines the reading destination of the original M1 based on the detection result of the detection unit 24. The control unit 31 is configured to read the original M1 from the ADF when the detection unit 24 detects the original M1. The control unit 31 is configured to read the original M1 from the FB when the detection unit 24 does not detect the original M1.

[0034] The control unit 31 may determine the reading destination of the original M1 based on the detection result of the cover detection unit 16. The control unit 31 may be configured to read the original M1 from the FB when the cover detection unit 16 detects that the cover 15 has been closed relative to the platen 12. This is because when the cover 15 changes from an open state to a closed state, there is a high possibility that the original M1 has been set on the platen 12.

[0035] The control unit 31 may determine the reading destination of the original M1 based on the detection results of the detection unit 24 and the detection results of the cover detection unit 16. The control unit 31 may be configured to read the original M1 from the FB when the detection unit 24 does not detect the original M1 and the cover detection unit 16 detects that the cover 15 has been closed relative to the platen 12. This is because when the original M1 is not set on the supply tray 19 and the cover 15 has changed from an open state to a closed state, there is a high possibility that the original M1 has been set on the platen 12.

[0036] The control unit 31 reads the original M1 based on the setting of the reading side. When the reading side is set to single-sided, the control unit 31 controls the reading unit 26 to read one side of the original M1. When the reading side is set to single-sided, the control unit 31 causes the first reading module 27 to function. When the reading side is set to double-sided, the control unit 31 controls the reading unit 26 to read both sides of the original M1. When the reading side is set to double-sided, the control unit 31 causes the first reading module 27 and the second reading module 28 to function.

[0037] The control unit 31 may be configured to continuously read the document M1. The control unit 31 may be configured to continuously read the document M1 from the FB and from the ADF. By continuously reading the document M1, the control unit 31 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 19 together as a single file. The control unit 31 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 19, thereby continuously reading the document M1 set in the supply tray 19. 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.

[0038] The control unit 31 may continuously read the document M1 from the FB and read another document M1 from the FB. In this case, the control unit 31 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 a single file.

[0039] The control unit 31 may continuously read one document M1 from the ADF and another document M1 from the ADF. In this case, the control unit 31 outputs the image data of the document M1 set on the supply tray 19 and the image data of the other document M1 set on the supply tray 19 together as a single file.

[0040] <Screen> Next, the screen displayed on the display unit 29 will be described. 2, before the start of reading of the original M1, a setting screen 41 is displayed. The setting screen 41 is, for example, a screen that can be transitioned to from a home screen. The home screen is a screen that is displayed on the display unit 29 when the image reading device 11 is in standby mode. In one example, when a user operates a read button on the home screen that causes the image reading device 11 to read the original M1, the setting screen 41 is displayed.

[0041] The setting screen 41 is a screen for setting the reading of the original M1. More specifically, the setting screen 41 is a screen for setting the reading side of the original M1. The user sets the reading side of the original M1 to one side or both sides on the setting screen 41 via the operation unit 30.

[0042] The setting screen 41 displays one or more setting fields. The setting screen 41 displays a reading side setting field 42. In one example, the setting screen 41 displays an output format setting field 43 and a color format setting field 44 in addition to the reading side setting field 42. The setting fields display the current settings for reading the document M1. The setting screen 41 is configured so that the settings corresponding to a setting field are changed by operating the setting field. The setting fields are operated by the user touching them with their fingertip or selecting them with the cursor.

[0043] The reading side setting field 42 displays the currently set reading side of the document M1. The reading side setting field 42 displays whether the reading side of the document M1 is set to one side or both sides.

[0044] The double-sided reading setting works when the first reading module 27 and the second reading module 28 are functioning, that is, when reading the original M1 from the ADF. Therefore, when reading the original M1 from the FB, the double-sided reading setting does not work even if double-sided is set for the reading side.

[0045] The output format setting field 43 displays the currently set output format of the image data. The output format setting field 43 displays that the output format of the image data is set to PDF, or that it is set to TIFF.

[0046] The output format may include single page, multi-page, etc. That is, either single page or multi-page may be set in the output format setting field 43. Single page means that when multiple documents M1 are continuously read, a file is output for each read side of the multiple documents M1. Multi-page means that when multiple documents M1 are continuously read, one file is output for the multiple documents M1. For example, when the output format is set to single-page PDF, the control unit 31 outputs the image data for each page in PDF. For example, when the output format is set to multi-page PDF, the control unit 31 combines multiple pages of image data and outputs them in PDF.

[0047] The single page and multi-page settings function when multiple documents M1 are scanned continuously, i.e., when documents M1 are scanned from the ADF. Therefore, when scanning documents M1 from the FB, the single page and multi-page settings do not function even if the output format is set to single page or multi-page.

[0048] The output format may include the opening direction. The opening direction is an item that determines the orientation of the back side relative to the front side when scanning both sides of the original M1. In the output format setting field 43, either top-bottom opening or left-right opening may be set. Top-bottom opening indicates that image data is output so that the front and back sides are closed top and bottom. Left-right opening indicates that image data is output so that the front and back sides are closed left and right. The closing position of the image data on the front side and the image data on the back side differs depending on the opening direction.

[0049] The opening direction setting is only effective when multiple documents M1 are scanned consecutively, i.e., when documents M1 are scanned from the ADF. Therefore, when scanning documents M1 from the FB, the opening direction setting does not function even if the opening direction is set in the output format.

[0050] The color format setting field 44 displays the color format of the image data that is currently set. The color format setting field 44 displays whether the color format of the image data is set to monochrome or color. When the color format is set to monochrome, the reading unit 26 reads the original M1 in monochrome. When the color format is set to color, the reading unit 26 reads the original M1 in three colors, RGB. The color format may include grayscale.

[0051] The setting screen 41 may display a multi-feed detection setting field that displays the current setting for multi-feed detection. The multi-feed detection setting field may, for example, display whether multi-feed detection is enabled or disabled. When multi-feed detection is enabled, the image reading device 11 causes the multi-feed detection unit 25 to function. The multi-feed detection setting functions when reading the original M1 from the ADF. Therefore, when reading the original M1 from the FB, the multi-feed detection setting does not function even if multi-feed detection is enabled.

[0052] The setting screen 41 may display a document protection setting field that displays the current setting for document protection. The document protection setting field may, for example, display whether document protection is enabled or disabled. Document protection is a setting that reduces the load on the document M1 during transport by slowing down the transport speed of the document M1 or stopping the document M1 midway. When document protection is enabled, the image reading device 11 controls the transport unit 20 to reduce the load on the document M1. The document protection setting functions when the document M1 is read from the ADF. Therefore, when the document M1 is read from the FB, the document protection setting does not function even if document protection is enabled.

[0053] The setting screen 41 may display a dirt detection setting field that displays the current setting for dirt detection. The dirt detection setting field may indicate whether dirt detection is enabled or disabled. Dirt detection is a setting for detecting dirt on the reading module. For example, dirt detection is a setting for detecting dirt on the second reading module 28. When dirt detection is enabled, the image reading device 11 controls the second reading module 28 to check whether the second reading module 28 is dirty. The control unit 31 detects dirt, for example, based on the amount of light detected by the second reading module 28. The dirt detection setting is enabled when reading the original M1 from the ADF. Therefore, even if dirt detection is enabled, the dirt detection setting is disabled when reading the original M1 from the FB. Dirt detection may be enabled by setting the dirt detection field to detect dirt on the first reading module 27. In this case, the dirt detection setting is enabled even when reading the original M1 from the FB.

[0054] The setting screen 41 may display a display field 45 that displays the reading destination of the original M1. The display field 45 may display that the original M1 will be read from the ADF or that the original M1 will be read from the FB. The reading destination determined by the control unit 31 is displayed in the display field 45. In one example, the reading destination is displayed in the display field 45 based on the detection result of the detection unit 24. That is, if the detection unit 24 detects the original M1, the display field 45 displays that the original M1 will be read from the ADF. If the detection unit 24 does not detect the original M1, the display field 45 displays that the original M1 will be read from the FB. The reading destination may be displayed in the display field 45 based on the detection result of the cover detection unit 16.

[0055] A back button 46 may be displayed on the setting screen 41. When the back button 46 is operated, the screen that was displayed before the transition is displayed. When the setting screen 41 is displayed from the home screen, operating the back button 46 displays the home screen.

[0056] A start button 47 may be displayed on the setting screen 41. The start button 47 is a button for starting the reading of the original M1. When the start button 47 is operated, the control unit 31 drives the reading destination displayed in the display field 45 to read the original M1.

[0057] A notification button 48 may be displayed on the setting screen 41. The notification button 48 is a button that displays a notification screen 61, which will be described later. In one example, the notification button 48 is displayed so as to correspond to the reading side setting field 42. More specifically, the notification button 48 is displayed within the reading side setting field 42. The notification button 48 may be displayed, for example, adjacent to the reading side setting field 42. By displaying the notification button 48 so as to correspond to the reading side setting field 42, the user can understand that the notification button 48 is a button related to setting the reading side. This makes it easier for the user to see the notification button 48 when setting the reading side. The notification button 48 may be displayed on other screens, not just the setting screen 41. For example, the notification button 48 may be displayed on the home screen.

[0058] As shown in FIG. 3, a continuation screen 51 may be displayed when reading of the original M1 is completed. The continuation screen 51 is a screen that inquires whether to continue reading the original M1. In other words, the continuation screen 51 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 31 accepts on the continuation screen 51 that the original M1 will be read continuously, it starts the next reading. When the control unit 31 accepts on the continuation screen 51 that the original M1 will not be read continuously, it outputs the image data that has been read so far as a file.

[0059] An end button 52 is displayed on the continuation screen 51. When the end button 52 is operated, the control unit 31 accepts that the document M1 will not be read continuously. When the end button 52 is operated, the control unit 31 outputs the image data that has been read so far as a file.

[0060] A continue button 53 is displayed on the continuation screen 51. When the continue button 53 is operated, the control unit 31 accepts that the document M1 will be read continuously. When the continue button 53 is operated, reading of the document M1 begins. That is, the control unit 31 starts continuous reading.

[0061] A stop button 54 is displayed on the continuation screen 51. When the stop button 54 is operated, the control unit 31 stops reading the document M1. When the stop button 54 is operated, the control unit 31 discards the image data that has been read so far.

[0062] A display field 45 may be displayed on the continuation screen 51. On the continuation screen 51, the display field 45 displays the reading destination of the document M1 during continued reading. As with the setting screen 41, the display field 45 displays the reading destination determined by the control unit 31. In one example, the reading destination is displayed in the display field 45 based on the detection result of the detection unit 24.

[0063] The continuation screen 51 may display a setting change button 55. The setting change button 55 is a button for changing settings for reading the original M1. When continuous scanning is in progress, there are restrictions on changing settings. When continuous scanning is in progress, settings related to the generation of image data, such as the scanning side, output format, and color format, cannot be changed. When continuous scanning is in progress, settings such as multifeed detection, original protection, and dirt detection can be changed.

[0064] Next, the notification screen 61 will be described. As shown in FIG. 4, the notification screen 61 is a screen that notifies the user that only one side of the document M1 set on the document tray 12 will be read. The notification screen 61 notifies the user that even if the reading side is set to both sides, only one side will be read when reading the document M1 from the FB. The setting screen 41 allows the user to set the reading side to both sides regardless of whether the reading destination is the ADF or the FB. Therefore, the user may mistakenly believe that both sides of the document M1 set on the document tray 12 can be read. The notification screen 61 is a screen that prevents such a user mistaken belief.

[0065] The notification screen 61 may not only notify the user of the setting of the reading surface, but also of the setting that does not function when reading the original M1 from the FB. For example, the notification screen 61 may notify the user that the multi-page setting does not function for the original M1 set on the platen 12, or that the multi-feed detection does not function for the original M1 set on the platen 12.

[0066] The notification screen 61 is displayed when a specific condition is satisfied. That is, the control unit 31 causes the display unit 29 to display the notification screen 61 when the specific condition is satisfied. The control unit 31 may also cause the display unit 29 to display the notification screen 61 when the notification button 48 is operated. In this case, the specific condition includes a condition that the notification button 48 is operated.

[0067] The notification screen 61 may be displayed based on the result of determining the reading destination. The notification screen 61 may be displayed when it is determined that the reading destination is FB. The notification screen 61 may be displayed when the detection unit 24 does not detect the original M1. In this case, the specific condition includes a condition where the detection unit 24 does not detect the original M1. The notification screen 61 may be displayed when the cover detection unit 16 detects that the cover 15 is closed. The notification screen 61 may be displayed when the cover detection unit 16 detects that the cover 15 is closed on the platen 12 and the detection unit 24 does not detect the original M1.

[0068] The notification screen 61 may be displayed when the start button 47 is operated and the detection unit 24 does not detect the original M1. In other words, the notification screen 61 may be displayed when the reading destination is FB at the timing when the start button 47 is operated on the setting screen 41. This reduces the risk that reading will start with the user misunderstanding the setting of the reading surface.

[0069] The notification screen 61 may be displayed when the reading destination is FB before the start of continuous reading. For example, the notification screen 61 may be displayed when the detection unit 24 does not detect the original M1 after the continuation screen 51 is displayed but before the start of continuous reading. The notification screen 61 may be displayed when the continue button 53 is operated and the detection unit 24 does not detect the original M1. This reduces the risk that continuous reading will start with the user misunderstanding the setting of the reading side.

[0070] The notification screen 61 may be displayed when the reading side is set to double-sided. That is, the specific condition may include a condition where the reading side is set to double-sided. For example, the notification screen 61 may be displayed when the reading side is set to double-sided and the reading destination is FB. The notification screen 61 may be displayed when the reading side is set to double-sided and the reading destination is FB at the time the start button 47 is operated. The notification screen 61 may be displayed when the reading side is set to double-sided and the reading destination is FB at the time the continue button 53 is operated, and the detection unit 24 does not detect the original M1. In this way, the specific condition may include a condition where the start button 47 is operated, the continue button 53 is operated, etc.

[0071] A close button 62 may be displayed on the notification screen 61. When the close button 62 is operated, the notification screen 61 closes. If the notification screen 61 is displayed at the timing to start reading, operating the close button 62 puts the start of reading of the original M1 on hold. This allows the user to change settings or change the setting destination of the original M1 before starting reading.

[0072] An OK button 63 is displayed on the notification screen 61. When the OK button 63 is operated, the notification screen 61 closes. If the notification screen 61 is displayed at the timing to start reading, operating the OK button 63 starts reading of the original M1. In other words, after the notification screen 61 closes, reading of the original M1 starts.

[0073] The notification screen 61 may be displayed as a transition from another screen. The notification screen 61 may be displayed as a transition from the setting screen 41 or the continuation screen 51. The notification screen 61 may be displayed as a pop-up on another screen. The notification screen 61 may be displayed on the setting screen 41 or the continuation screen 51.

[0074] <Flowchart> Next, an example of the notification process will be described. The notification process is a process for displaying a notification screen 61 on the display unit 29. The notification process is executed by the control unit 31. As examples of the notification process, a first notification process, a second notification process, a third notification process, and a fourth notification process will be described. In one example, the first notification process, the second notification process, and the third notification process are executed in conjunction with the display of the setting screen 41. The fourth notification process is executed in conjunction with the display of the continuation screen 51.

[0075] 5, in the first notification process, the control unit 31 determines in step S11 whether the notification button 48 has been operated. If the notification button 48 has been operated, the control unit 31 proceeds to step S12. If the notification button 48 has not been operated, the control unit 31 repeats the process of step S11. That is, the control unit 31 waits until the notification button 48 is operated.

[0076] In step S12, the control unit 31 causes the display unit 29 to display the notification screen 61. Thereafter, the control unit 31 ends the first notification process and starts the first notification process again. The control unit 31 repeats the first notification process while the setting screen 41 is displayed. When the setting screen 41 closes, the control unit 31 ends the first notification process.

[0077] 6, in the second notification process, the control unit 31 determines in step S21 whether the reading destination is the FB. If the reading destination is the FB, for example, if the detection unit 24 does not detect the original M1, the control unit 31 proceeds to step S22. If the reading destination is the ADF, for example, if the detection unit 24 detects the original M1, the control unit 31 repeats the process of step S21.

[0078] In step S21, if the cover detection unit 16 detects that the cover 15 is closed on the platen 12 and the detection unit 24 does not detect the document M1, the control unit 31 may proceed to step S22.

[0079] In step S22, the control unit 31 determines whether the reading side is set to double-sided. If the reading side is set to double-sided, the control unit 31 proceeds to step S23. If the reading side is set to single-sided, the control unit 31 returns to step S21.

[0080] In step S23, the control unit 31 causes the display unit 29 to display the notification screen 61. Thereafter, the control unit 31 ends the second notification process. The second notification process may be executed in parallel with the first notification process.

[0081] 7, in the third notification process, the control unit 31 determines in step S31 whether the start button 47 has been operated. If the start button 47 has been operated, the control unit 31 proceeds to step S32. If the start button 47 has not been operated, the control unit 31 repeats the process of step S31. That is, the control unit 31 waits until the start button 47 is operated.

[0082] In step S32, the control unit 31 determines whether the reading destination is the FB. If the reading destination is the FB, for example, if the detection unit 24 does not detect the document M1, the control unit 31 proceeds to step S33. If the reading destination is the ADF, for example, if the detection unit 24 detects the document M1, the control unit 31 ends the third notification process.

[0083] In step S32, if the cover detection unit 16 detects that the cover 15 is closed on the platen 12 and the detection unit 24 does not detect the document M1, the control unit 31 may proceed to step S33.

[0084] In step S33, the control unit 31 determines whether the reading side is set to double-sided. If the reading side is set to double-sided, the control unit 31 proceeds to step S34. If the reading side is set to single-sided, the control unit 31 ends the third notification process.

[0085] In step S34, the control unit 31 causes the display unit 29 to display the notification screen 61. Thereafter, the control unit 31 ends the third notification process. The third notification process may be executed in parallel with the first notification process. The third notification process may be executed in parallel with the second notification process. The second notification process may be executed in parallel with the first notification process and the second notification process.

[0086] 8, in the fourth notification process, the control unit 31 determines in step S41 whether the continue button 53 has been operated. If the continue button 53 has been operated, the control unit 31 proceeds to step S42. If the continue button 53 has not been operated, the control unit 31 repeats the process of step S41. That is, the control unit 31 waits until the continue button 53 is operated.

[0087] In step S42, the control unit 31 determines whether the reading destination is the FB. If the reading destination is the FB, for example, if the detection unit 24 does not detect the original M1, the control unit 31 proceeds to step S43. If the reading destination is the ADF, for example, if the detection unit 24 detects the original M1, the control unit 31 ends the fourth notification process.

[0088] In step S42, if the cover detection unit 16 detects that the cover 15 is closed on the platen 12 and the detection unit 24 does not detect the document M1, the control unit 31 may proceed to step S43.

[0089] In step S43, the control unit 31 determines whether the reading side is set to double-sided. If the reading side is set to double-sided, the control unit 31 proceeds to step S44. If the reading side is set to single-sided, the control unit 31 ends the fourth notification process.

[0090] In step S44, the control unit 31 causes the display unit 29 to display the notification screen 61. Thereafter, the control unit 31 ends the fourth notification process. The continuation screen 51 may display the notification button 48, and in this case, the first notification process may be executed in parallel with the fourth notification process.

[0091] <Actions and Effects of the Example> Next, the operation and effects of the above embodiment will be described. (1) When a specific condition is satisfied, the control unit 31 causes the display unit 29 to display a notification screen 61 notifying the user that only one side of the document M1 set on the document platen 12 will be read. According to the above configuration, the user can understand by checking the notification screen 61 that the image reading device 11 cannot read both sides of the document M1 set on the document platen 12. This reduces the risk of the user misunderstanding the setting of the reading side.

[0092] (2) When the notification button 48 is operated, the control unit 31 displays the notification screen 61 on the display unit 29. According to the above configuration, the user can check the notification screen 61 by operating the notification button 48. By checking the notification screen 61, the user can understand that the image reading device 11 cannot read both sides of the document M1 set on the document table 12.

[0093] (3) The notification button 48 is displayed to correspond to the reading side setting field 42. According to the above configuration, the user can easily see the notification button 48 when checking the reading side setting field 42. This makes it easier for the user to check the notification screen 61.

[0094] (4) When the detection unit 24 does not detect the document M1, the control unit 31 causes the display unit 29 to display a notification screen 61. When the document M1 is not set in the supply tray 19, there is a high possibility that the document M1 is set on the document table 12. Therefore, according to the above configuration, when there is a high possibility that the document M1 is set on the document table 12, the user can check the notification screen 61.

[0095] (5) If the detection unit 24 does not detect the document M1 before the start of continuous reading, the control unit 31 causes the display unit 29 to display the notification screen 61. According to the above configuration, if there is a high possibility that the document M1 is set on the document table 12 during continuous reading, the user can check the notification screen 61.

[0096] (6) When the cover detection unit 16 detects that the cover 15 is closed on the platen 12 and the detection unit 24 does not detect the document M1, the control unit 31 causes the display unit 29 to display the notification screen 61. When the cover 15 is opened on the platen 12, the document M1 is set on the platen 12. Therefore, when the cover 15 is closed on the platen 12, there is a high possibility that the document M1 has been set on the platen 12. Therefore, when the cover 15 is closed on the platen 12 and the detection unit 24 does not detect the document M1, there is an even higher possibility that the document M1 has been set on the platen 12. According to the above configuration, the user can see the notification screen 61 when there is an even higher possibility that the document M1 has been set on the platen 12.

[0097] (7) When the start button 47 is operated and the detection unit 24 does not detect the document M1, the control unit 31 causes the display unit 29 to display the notification screen 61. According to the above configuration, the user can check the notification screen 61 when starting to read the document M1.

[0098] (8) The control unit 31 starts reading the document M1 after closing the notification screen 61. According to the above configuration, the possibility that reading of the document M1 will start while the user still has an incorrect understanding of the setting of the reading side is reduced.

[0099] <Technical philosophy> The technical concepts and effects that can be understood from the above-described embodiment and modified examples will be described below.

[0100] (A) An image reading device includes a platen on which documents are set, a supply tray on which documents are set, a transport unit that transports the documents set on the supply tray, a reading unit that reads the documents set on the platen and the documents transported from the supply tray, a display unit that displays a setting screen for setting the reading side of the document, and a control unit, and when specific conditions are met, the control unit causes the display unit to display a notification screen notifying the user that only one side of the document set on the platen will be read.With the above configuration, by checking the notification screen, the user can understand that the image reading device cannot read both sides of the document set on the platen.This reduces the risk of the user misunderstanding the setting of the reading side.

[0101] (B) In the image reading device, a notification button may be displayed on the setting screen, and the control unit may cause the display unit to display the notification screen when the notification button is operated. According to the above configuration, a user can check the notification screen by operating the notification button. By checking the notification screen, the user can understand that the image reading device cannot read both sides of the document set on the document platen.

[0102] (C) In the image reading device, the setting screen may display a reading side setting field that displays the currently set reading side of the document, and the notification button may be displayed to correspond to the reading side setting field. With the above configuration, the user can easily see the notification button when checking the reading side setting field. This makes it easier for the user to check the notification screen.

[0103] (D) The image reading device may include a detection unit that detects a document set in the supply tray, and the control unit may cause the display unit to display the notification screen when the detection unit does not detect a document. If no document is set in the supply tray, there is a high possibility that a document is set on the document table. Therefore, with the above configuration, the user can check the notification screen when there is a high possibility that a document is set on the document table.

[0104] (E) In the image reading device, when the reading of the document is completed, the control unit may cause the display unit to display a continuation screen inquiring whether to execute continuous reading to continuously read the document, and if the detection unit does not detect the document before the start of the continuous reading, cause the display unit to display the notification screen. According to the above configuration, if there is a high possibility that a document will be set on the document table during continuous reading, the user can check the notification screen.

[0105] (F) The image reading device may include a cover that overlaps the platen and a cover detection unit that detects whether the cover is open or closed relative to the platen, and the control unit may cause the display unit to display the notification screen when the cover detection unit detects that the cover is closed relative to the platen and when the detection unit does not detect a document. When the cover is opened relative to the platen, a document is placed on the platen. Therefore, when the cover is closed relative to the platen, there is a high possibility that a document has been placed on the platen. Therefore, when the cover is closed relative to the platen and the detection unit does not detect a document, there is an even higher possibility that a document has been placed on the platen. According to the above configuration, the user can check the notification screen when there is an even higher possibility that a document has been placed on the platen.

[0106] (G) In the image reading device, the setting screen may display a start button for starting reading of the document, and the control unit may cause the display unit to display the notification screen when the start button is operated and the detection unit does not detect the document. According to the above configuration, the user can check the notification screen when starting reading of the document.

[0107] (H) In the image reading device, the control unit may start reading the document after closing the notification screen. This configuration reduces the risk that reading of the document will start while the user is still erroneously recognizing the reading surface setting.

[0108] (I) A control method for an image reading device includes a platen 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 platen and the document transported from the supply tray, and a display unit that displays a setting screen for setting the reading side of the document, and includes displaying a notification screen on the display unit that notifies the user that only one side of the document set on the platen will be read when a specific condition is met.The above method provides the same effects as the image reading device described above.
