Mode for Carrying Out the Invention

[0010] Hereinafter, an embodiment of the reading device will be described with reference to the drawings. The reading device is, for example, a sheet feed scanner in which a fixed reading unit reads a document by transporting the document such as paper or film.

[0011] <Configuration of the Reading Device> As shown in FIGS. 1 and 2, the reading device 11 includes a housing 12 and a support portion 13. The housing 12 is supported by the support portion 13. The support portion 13 is installed on an installation surface F1. The installation surface F1 is, for example, a horizontal plane. The housing 12 is configured to be rotatable with respect to the support portion 13.

[0012] The housing 12 is configured to be able to switch its posture. The housing 12 is configured to be able to switch to a plurality of postures having different inclination angles with respect to the installation surface F1. For example, when the housing 12 rotates with respect to the support portion 13, the posture of the housing 12 is switched.

[0013] The housing 12 is configured to be able to switch its posture between a first posture and a second posture. The housing 12 has different tilt angles with respect to the installation surface F1 in the first posture and the second posture. In FIG. 1, the housing 12 is in the first posture. In FIG. 2, the housing 12 is in the second posture. When the housing 12 rotates clockwise in FIG. 1, the housing 12 switches from the first posture to the second posture. The inclination of the housing 12 with respect to the support portion 13 changes between the case where the housing 12 is in the first posture and the case where the housing 12 is in the second posture. When the housing 12 is in the first posture, the foot space of the reading device 11 is reduced compared to the case where the housing 12 is in the second posture. In addition to the first posture and the second posture, the housing 12 may be configured to be able to switch to a third posture.

[0014] A supply port 14 and one or more discharge ports are open in the housing 12. The supply port 14 is an opening through which the original document M1 is supplied. Through the supply port 14, the original document M1 is supplied into the housing 12. The discharge port is an opening through which the original document M1 is discharged. Through the discharge port, the original document M1 is discharged from the housing 12. In this example, a first discharge port 15 and a second discharge port 16 are open in the housing 12.

[0015] The reading device 11 includes a conveyance path 17. The conveyance path 17 is a path along which the original document M1 is conveyed toward a reading unit 31 described later. The conveyance path 17 extends from the supply port 14 to the reading unit 31. Therefore, the original document M1 conveyed along the conveyance path 17 is supplied to the reading unit 31. The conveyance path 17 extends, for example, linearly or in a straight line. The direction in which the conveyance path 17 extends is the conveyance direction D1.

[0016] When the posture of the housing 12 is switched, the tilt angle of the conveyance path 17 changes. In this example, when the housing 12 is in the second posture, the tilt angle of the conveyance path 17 with respect to the installation surface F1 becomes gentler than when the housing 12 is in the first posture.

[0017] The reading device 11 includes an output path 18. The output path 18 is the path through which the document M1 read by the reading unit 31 is output. The output path 18 includes a first output path 19 and a second output path 20. The first output path 19 and the second output path 20 are paths to which the document M1 is output to different destinations. The output path 18 may include three or more paths to which the document M1 is output to different destinations.

[0018] The first discharge path 19 extends from the reading unit 31 to the first discharge port 15. The second discharge path 20 extends from the reading unit 31 to the second discharge port 16. The first discharge path 19 and the second discharge path 20 extend in a way that branches off, for example, along the way.

[0019] The discharge path 18 is configured to allow switching between a first discharge path 19 and a second discharge path 20 as the path used to discharge the original document M1. When the first discharge path 19 is selected, the original document M1 read by the reading unit 31 is discharged through the first discharge path 19. When the second discharge path 20 is selected, the original document M1 read by the reading unit 31 is discharged through the second discharge path 20.

[0020] The first discharge path 19 has a curved portion 21. The curved portion 21 is the part of the first discharge path 19 that curves. The curved portion 21 extends, for example, from the branching point with the second discharge path 20 in the first discharge path 19. The curved portion 21 curves, for example, in a U shape. Therefore, the document M1 transported through the first discharge path 19 is discharged while curving. The first discharge path 19 is used, for example, when the housing 12 is in a first orientation. That is, when the housing 12 is in a first orientation, the document M1 is transported through the first discharge path 19.

[0021] The second discharge path 20 is, for example, straight or extends in a linear manner. The direction in which the second discharge path 20 extends is, for example, the transport direction D1. Unlike the first discharge path 19, the second discharge path 20 does not include any curved sections. Therefore, the document M1 transported through the second discharge path 20 is discharged without curving. The second discharge path 20 is used, for example, when the housing 12 is in the second orientation. That is, when the housing 12 is in the second orientation, the document M1 is transported through the second discharge path 20. In this example, the path used is switched in the reading device 11 depending on the orientation of the housing 12.

[0022] In the scanner 11, the appropriate path for ejecting the document M1 differs depending on the type of document M1. That is, the appropriate path differs depending on the type of document M1. For example, when scanning a rigid document M1, the second ejection path 20 is preferable. If the document M1 is rigid, there is a risk of damage to the document M1 when it passes through the curved portion 21. Examples of rigid documents M1 include cards and laminated documents M1.

[0023] For booklets such as passports and brochures, the preferred route of use is the second discharge route 20. This is because booklets may get stuck in the curved section 21 when transported through the first discharge route 19.

[0024] In this example, for instance, the first output path 19 can be used when scanning a document M1 with low rigidity. A document M1 with low rigidity is, for example, paper. When scanning a document M1 with low rigidity, the output path used is not limited to the first output path 19; the second output path 20 may also be used. In other words, there are restrictions on the type of document M1 when using the first output path 19. On the other hand, there are no restrictions on the type of document M1 when using the second output path 20.

[0025] In this example, the second output path 20 is used when scanning cards, laminated documents M1, booklets, etc. Typically, when users have the reader 11 scan cards, laminated documents M1, booklets, etc., they usually scan only one document M1 at a time. In other words, users rarely have the reader 11 scan multiple cards or multiple booklets in succession. Therefore, in this example, when the orientation of the housing 12 is the second orientation, i.e., when the usage path is the second output path 20, the reader 11 scans only one document M1. In this example, when the usage path is the second output path 20, the reader 11 does not scan multiple documents M1 in succession.

[0026] The reading device 11 includes a switching member 22. The switching member 22 is, for example, a flap. The switching member 22 switches the usage path between the first discharge path 19 and the second discharge path 20. The switching member 22 switches the usage path by blocking either the first discharge path 19 or the second discharge path 20. When the switching member 22 blocks the first discharge path 19, the usage path becomes the second discharge path 20. When the switching member 22 blocks the second discharge path 20, the usage path becomes the first discharge path 19.

[0027] The switching member 22 is linked to, for example, the orientation of the housing 12. When the housing 12 is in the first orientation, the switching member 22 blocks the second discharge path 20. When the housing 12 is in the second orientation, the switching member 22 blocks the first discharge path 19. The user switches the usable path by, for example, manually switching the orientation of the housing 12. The switching member 22 may be displaced independently of the orientation of the housing 12. That is, the path may be switched by switching the switching member 22 using a drive source, regardless of the orientation of the housing 12.

[0028] The reading device 11 may include, for example, one or more path sensors for detecting the usage path. The path sensor may detect the usage path by detecting the switching member 22, for example. The path sensor may also detect the usage path by detecting the orientation of the housing 12. The reading device 11 may include, for example, a first path sensor 23 and a second path sensor 24.

[0029] The first path sensor 23 is configured to detect, for example, a switching member 22 that blocks the second discharge path 20. When the first path sensor 23 detects the switching member 22, it can be determined that the path being used is the first discharge path 19.

[0030] The second path sensor 24 is configured to detect, for example, a switching member 22 that blocks the first discharge path 19. When the second path sensor 24 detects the switching member 22, it can be determined that the path being used is the second discharge path 20.

[0031] The reading device 11 may determine that the usage path is the first discharge path 19 when the first path sensor 23 detects the switching member 22, and determine that the usage path is the second discharge path 20 when the first path sensor 23 does not detect the switching member 22. Alternatively, the reading device 11 may determine that the usage path is the second discharge path 20 when the second path sensor 24 detects the switching member 22, and determine that the usage path is the first discharge path 19 when the second path sensor 24 does not detect the switching member 22. In this case, only one path sensor is needed. The path sensor is not limited to a sensor that detects the switching member 22; for example, it could be a gyro sensor that detects the orientation of the housing 12. That is, the reading device 11 may identify the usage path from the orientation of the housing 12. The reading device 11 may also have separate sensors for detecting the orientation of the housing 12 and for detecting the position of the switching member 22.

[0032] The scanner 11 includes a transport unit 25. The transport unit 25 is configured to transport the original document M1. The transport unit 25 transports the original document M1 along a transport path 17. The transport unit 25 transports the original document M1 along an discharge path 18. The transport unit 25 includes, for example, one or more rollers. The transport unit 25 includes, for example, a first roller pair 26 and a second roller pair 27. The transport unit 25 may also include, for example, a feed roller pair 28.

[0033] The first roller pair 26 is located in the transport path 17. The second roller pair 27 is located in the discharge path 18. The feed roller pair 28 is located in the transport path 17. The feed roller pair 28 is located upstream of the first roller pair 26 in the transport path 17. In the transport direction D1, the feed roller pair 28, the first roller pair 26, and the second roller pair 27 are arranged in this order. The first roller pair 26, the second roller pair 27, and the feed roller pair 28 transport the document M1 by rotating while gripping the document M1.

[0034] The second roller pair 27 is located in the discharge path 18 at the branching point between the first discharge path 19 and the second discharge path 20. Therefore, the first discharge path 19 and the second discharge path 20 branch off from the location where the second roller pair 27 is located. The first roller pair 26 and the second roller pair 27 are positioned so as to sandwich the reading unit 31 in the transport direction D1.

[0035] The feed roller pair 28 is a pair of rollers for separating the original document M1 into individual sheets. The feed roller pair 28 is configured, for example, by including a roller whose coefficient of friction with respect to the original document M1 is higher than the coefficient of friction between the original documents M1. For example, the feed roller pair 28 has a feed roller 28A and a separation roller 28B. The feed roller 28A rotates in a driven manner. The coefficient of friction of the separation roller 28B with respect to the original document M1 is higher than the coefficient of friction between the original documents M1. The separation roller 28B is usually subjected to a rotational load, for example, by a torque limiter. Therefore, when the feed roller 28A and the separation roller 28B hold multiple original documents M1, the separation roller 28B is less likely to rotate in a driven manner compared to the driving rotation of the feed roller 28A. In other words, the feed roller 28A and the separation roller 28B separate the original documents M1 into individual sheets. This reduces the risk of multiple original documents M1 being transported stacked on top of each other.

[0036] In this example, when the usage path is the second discharge path 20, that is, when the orientation of the housing 12 is the second orientation, the document separation function of the feed roller pair 28 is stopped. For example, by turning off the rotational load applied to the separation roller 28B by the torque limiter, the document separation function of the feed roller pair 28 is stopped. In this case, the separation roller 28B becomes more easily influenced by the rotation of the feed roller 28A. The stopping of the document separation function of the feed roller pair 28 is advantageous, for example, when scanning a booklet. When scanning a booklet, if the document separation function of the feed roller pair 28 is functioning, there is a risk that the booklet cannot be transported properly. Also, in this example, when the usage path is the second discharge path 20, multiple documents M1 are not scanned continuously, so there is no problem even if the document separation function of the feed roller pair 28 is stopped.

[0037] The scanner 11 is equipped with a tray 29. The tray 29 is attached to the housing 12. The tray 29 extends from inside the housing 12 to outside the housing 12 through a feed port 14. Documents M1 before scanning are loaded onto the tray 29. One or more documents M1 are loaded onto the tray 29. The documents M1 are loaded onto the tray 29 with their leading edges entering the feed port 14. The leading edges of the documents M1 loaded onto the tray 29 abut against the feed roller pair 28. More specifically, the leading edges of the documents M1 loaded onto the tray 29 abut against the feed roller 28A.

[0038] The reading device 11 comprises one or more reading units 31. The reading units 31 are housed in the casing 12. The reading units 31 are configured to read the original document M1. The reading units 31 read the original document M1 as it is transported along the transport path 17.

[0039] The reading device 11 includes, for example, two reading units 31. The two reading units 31 are located at the connection point between the transport path 17 and the discharge path 18. The two reading units 31 face each other. The reading units 31 are elongated in the scanning direction D2. The scanning direction D2 intersects the transport direction D1. If the scanning direction D2 is referred to as the main scanning direction, then the transport direction D1 can also be said to be the secondary scanning direction.

[0040] The two reading units 31 each read different sides of the original document M1. One of the two reading units 31 reads the front surface of the original document M1. The other reading unit 31 reads the back surface of the original document M1. As a result, the reading device 11 reads either one side or both sides of the original document M1.

[0041] The reading unit 31 includes, for example, a light source 32, a plurality of image sensors 33, and a background plate 34. The light source 32 is, for example, an LED or a fluorescent lamp. The light source 32 irradiates light toward the opposing reading unit 31.

[0042] Multiple image sensors 33 are arranged in the scanning direction D2. The multiple image sensors 33 are modularized. The image sensors 33 are, for example, contact-type image sensors. More specifically, the image sensors 33 are CMOS image sensors. The image sensors 33 convert the received light into photoelectric power. The image sensors 33 output an output signal with a value corresponding to the amount of light received.

[0043] The image sensor 33 may be a monochrome sensor or a color sensor. The reading unit 31 may be configured to read the original document M1 in full color. For example, the reading unit 31 may be configured to read the original document M1 using three colors: RGB. The reading unit 31 may also be configured to read the original document M1 in grayscale.

[0044] The background plate 34 faces, for example, an image sensor 33 and a light source 32 of another reading unit 31. Light is shone onto the background plate 34 from the light source 32 of the opposing reading unit 31. The background plate 34 reflects the shone light. The light reflected by the background plate 34 enters the image sensor 33 of the reading unit 31 facing the background plate 34. The background plate 34 is read as a background along with the original document M1 by the image sensor 33.

[0045] The reading device 11 includes a display unit 35. The display unit 35 is mounted on the housing 12. The display unit 35 notifies the user of information, for example, by displaying information. The display unit 35 is, for example, a touch panel. The display unit 35 also serves as a reception unit for receiving user operations, for example. The display unit 35 is not limited to a touch panel; it may be a simple display. In this case, the reading device 11 may also be equipped with buttons, switches, etc., as separate reception units. The information displayed by the display unit 35 will be described later.

[0046] As shown in Figure 3, the reading device 11 includes a control unit 36. The control unit 36 ​​controls the reading device 11. For example, the control unit 36 ​​controls the transport unit 25, the reading unit 31, and the display unit 35.

[0047] The control unit 36 ​​may be a circuit including one or more processors that perform various processes according to a computer program. The control unit 36 ​​may also be a circuit including one or more dedicated hardware circuits, such as application-specific integrated circuits, that perform at least some of the various processes. The control unit 36 ​​may also be a circuit including a combination of processors and hardware circuits. The processor includes a CPU and memory such as RAM and ROM, where the memory stores program code or instructions configured to cause the CPU to perform processes. Memory, i.e., computer-readable media, includes any readable media accessible by a general-purpose or dedicated computer.

[0048] The control unit 36 ​​is configured to acquire route information, which is information indicating the route being used. The control unit 36 ​​acquires route information from, for example, the first route sensor 23 and the second route sensor 24. For example, the control unit 36 ​​acquires route information from the first route sensor 23 indicating that the route being used is the first discharge route 19. For example, the control unit 36 ​​acquires route information from the second route sensor 24 indicating that the route being used is the second discharge route 20. This allows the control unit 36 ​​to determine the current route being used.

[0049] The control unit 36 ​​has a storage unit 37. The storage unit 37 is, for example, the memory described above. The storage unit 37 stores the program 38. The control unit 36 ​​causes the display unit 35 to display information by executing the program 38.

[0050] The control unit 36 ​​acquires image data from the reading unit 31. More specifically, the control unit 36 ​​receives an output signal from the reading unit 31. The control unit 36 ​​acquires image data by performing A / D conversion on the output signal. When acquiring image data, the control unit 36 ​​may apply shading correction and gamma correction to the output signal.

[0051] The control unit 36 ​​is configured to communicate with a computer 39 operated by the user. The computer 39 has a driver 40 installed for communicating with the reader 11. The computer 39 can be, for example, a personal computer or a smartphone.

[0052] <Display section> Next, the information displayed by the display unit 35 will be described. The information displayed by the display unit 35 is controlled by the control unit 36.

[0053] As shown in Figure 4, the display unit 35 displays the settings screen 41. The settings screen 41 is a screen for setting the scanning settings, which are settings related to scanning the document M1. The settings screen 41 is displayed, for example, when the home screen of the display unit 35 is operated. The settings screen 41 may also be displayed on the display unit 35 when the document M1 is placed in the tray 29. On the settings screen 41, the scanning settings are set by the user's operation.

[0054] The settings screen 41 displays the start button 42. When the start button 42 is pressed, the control unit 36 ​​receives an instruction to start scanning the document M1. In other words, once the scanning settings are configured and the start button 42 is pressed, the document M1 is scanned according to those scanning settings.

[0055] The settings screen 41 displays multiple setting items 43. Each setting item 43 indicates the content of the read settings. Each setting item 43 displays settings that the user can select. The user can configure multiple setting items 43, for example, by operating the settings screen 41. One of the multiple setting items 43 may be called the first setting item, and another setting item 43 different from the first setting item may be called the second setting item.

[0056] The scanning settings include, for example, a size item 44, which is a setting item 43 indicating the size of the document. The size item 44 allows selection of options such as A4 paper, B5 paper, automatic detection, card, or booklet. In other words, the size item 44 indicates whether the document M1 is a card or a booklet. Automatic detection is a setting that automatically detects the size of the document. When automatic detection is set, the control unit 36 ​​automatically detects the size of the document from the image data. Note that automatic detection is typically used when scanning paper.

[0057] The scanning settings include, for example, a lamination item 45, which is a setting item 43 indicating lamination. The lamination item 45 indicates whether the document M1 is laminated or not. The lamination item 45 can be set to, for example, ON or OFF. When the lamination item 45 is ON, it indicates that the laminated document M1 will be scanned. When the lamination item 45 is OFF, it indicates that the unlaminated document M1 will be scanned. When the lamination item 45 is ON, an area larger than the size of the document M1 set by the size item 44 will be scanned. This is because, if the document M1 is laminated, it is necessary to scan the area including the lamination.

[0058] The scanning settings include, for example, a format item 46, which is a setting item 43 indicating the format in which the image data will be output. In the format item 46, for example, single-page PDF, multi-page PDF, single-page TIFF, multi-page TIFF, single-page PDF / A, multi-page PDF / A, etc. Single-page means that when multiple documents M1 are scanned consecutively, a file is output for each page scanned of the multiple documents M1. Multi-page means that when multiple documents M1 are scanned consecutively, one file is output for all of the multiple documents M1. For example, if the format item 46 is single-page PDF, the control unit 36 ​​outputs the image data as a PDF for each page. For example, if the format item is multi-page PDF, the control unit 36 ​​combines multiple pages of the image data and outputs it as a PDF.

[0059] The scanning settings include, for example, a scanning item 47, which is a setting item 43 indicating double-sided scanning. Scanning item 47 indicates whether or not to scan both sides of the document M1. Scanning item 47 allows you to select, for example, double-sided or single-sided. If scanning item 47 is set to double-sided, it indicates that both sides of the document M1 will be scanned. If scanning item 47 is set to single-sided, it indicates that one side of the document M1 will be scanned.

[0060] The scanning settings include, for example, an opening item 48, which is a setting item 43 indicating the opening direction of the document M1. 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 document M1. Therefore, the opening item 48 becomes selectable, for example, when both sides are selected in the scanning item 47. The opening item 48 allows you to select either top / bottom opening or left / right opening. Depending on the opening direction, the closing position of the image data on the front side and the image data on the back side will differ. In other words, the closing position of the image data is set according to the opening direction. If the opening direction is top / bottom opening, it indicates that the document M1 will be scanned so that the front and back sides are closed at the top and bottom. If the opening direction is left / right opening, it indicates that the document M1 will be scanned so that the front and back sides are closed at the left and right.

[0061] The reading settings include, for example, a processing item, which is a setting item 43 indicating the image processing to be performed on the image data. The processing item indicates whether or not to perform a predetermined image processing on the image data. The processing item includes, for example, a border removal item 49 and a blank page removal item 50. The border removal item 49 and the blank page removal item 50 can be selected as ON or OFF, respectively.

[0062] Edge removal is the process of erasing the shadow of the original document M1 that appears around the edges of the image data. When edge removal item 49 is ON, it indicates that the shadow of the original document M1 that appears around the edges of the image data will be erased. Blank page removal is the process of deleting blank page data contained in the image data. When blank page removal item 50 is ON, it indicates that the blank page data will be deleted from the image data.

[0063] The control unit 36 ​​acquires the reading settings and route information, for example, when the start button 42 is operated. The control unit 36 ​​compares the reading settings and route information. That is, the control unit 36 ​​compares the setting item 43 with the route information. If the control unit 36 ​​determines that the route indicated by the route information is suitable for the reading settings, it starts reading the document M1. That is, the control unit 36 ​​transports the document M1 loaded on the tray 29 to the transport unit 25. If the control unit 36 ​​determines that the route is not suitable for the reading settings, it displays a message on the display unit 35 prompting the user to change the reading settings, a message prompting the user to change the route, or a message indicating both.

[0064] The control unit 36 ​​may compare the reading settings with the route information not only when the start button 42 is operated, but also while the reading settings are being configured on the settings screen 41. For example, the control unit 36 ​​may acquire route information when the reading settings are changed on the settings screen 41. The control unit 36 ​​may compare the changed reading settings with the acquired route information. If the control unit 36 ​​determines that the route used is unsuitable for the reading settings, it will display on the display unit 35 a message prompting the user to change the reading settings, a message prompting the user to change the route used, or a message indicating both. Note that "while the reading settings are being configured on the settings screen 41" may refer to the period from when the settings screen 41 is displayed on the display unit 35 until the user completes setting the reading settings. For example, "while the reading settings are being configured on the settings screen 41" may include the period from when the display on the display unit 35 transitions from the home screen to the settings screen 41 until the start button 42 is operated. For example, "while the reading settings are being configured on the settings screen 41" may include the timing when setting item 43 is operated on the settings screen 41.

[0065] As shown in Figure 5, the control unit 36 ​​displays a recommended display 51 on the display unit 35 based on the reading settings and route information. The recommended display 51 is a display prompting the user to change the reading settings or to change the route used. Therefore, the recommended display 51 is a display that prompts the user to change the reading settings, a display that prompts the user to change the route used, or a display that shows both. The recommended display 51 includes, for example, a display that shows reading settings suitable for the route used, or a display that shows a route suitable for the reading settings.

[0066] The recommendation display 51 is, for example, a message. The recommendation display 51 is, for example, displayed over the settings screen 41. The recommendation display 51 is, for example, displayed as a pop-up. The control unit 36 ​​prompts the user to change the reading settings or the usage path using the recommendation display 51. By seeing the recommendation display 51, the user understands that they should change the reading settings or the usage path in order to properly read the document M1. When the user changes the reading settings or the usage path, the document M1 is ejected using a usage path suitable for the reading settings. Conversely, the document M1 is read using reading settings suitable for the usage path.

[0067] In the scanner 11, the optimal path for ejecting the original document M1 differs depending on the scanning settings. For example, as mentioned above, the optimal path for ejecting the original document M1 differs depending on the type of original document M1. The type of original document M1 is set by the size item 44. There are optimal combinations of the size item 44 and the usage path for scanning the original document M1. There are also optimal combinations of other setting items 43, such as the format item 46 and the scanning item 47, with the usage path. Figure 6 shows an example of a combination of scanning settings and usage path that displays the recommended display 51.

[0068] As shown in Figure 6, when the lamination item 45 is ON and the usage path is the first discharge path 19, the control unit 36 ​​determines that the usage path is unsuitable for the reading setting. Therefore, when the reading setting indicates that the original document M1 is laminated and the usage path is the first discharge path 19, the control unit 36 ​​displays the recommendation display 51 on the display unit 35.

[0069] If the lamination option is ON, there is a high probability that a laminated document M1 will be supplied to the scanner 11. Therefore, if the usage path is the first discharge path 19, there is a risk of damage to the document M1. Consequently, in this case, scanning of the document M1 is prohibited until the scanning setting is changed or the usage path is changed. That is, if the lamination option 45 is ON and the usage path is the first discharge path 19, the control unit 36 ​​will not start scanning the document M1. If the lamination option 45 is ON and the usage path is the first discharge path 19, the control unit 36 ​​will display a recommended display 51 on the display unit 35 as shown in Figure 5. The user will check the recommended display 51 and change the lamination option 45 to OFF or change the usage path to the second discharge path 20.

[0070] As shown in Figure 6, if the size item 44 is a card and the usage path is the first discharge path 19, the control unit 36 ​​determines that the usage path is unsuitable for the reading setting. Similarly, if the size item 44 is a booklet and the usage path is the first discharge path 19, the control unit 36 ​​also determines that the usage path is unsuitable for the reading setting. Therefore, if the reading setting indicates that the document M1 is a card or booklet and the usage path is the first discharge path 19, the control unit 36 ​​displays the recommended display 51 on the display unit 35.

[0071] If the size item 44 is a card, there is a high probability that the card will be supplied to the reader 11. Therefore, if the usage path is the first discharge path 19, there is a risk that the original document M1 may be damaged. Accordingly, in this case, reading of the original document M1 is prohibited until the reading setting is changed or the usage path is changed. In other words, if the size item 44 is a card and the usage path is the first discharge path 19, the control unit 36 ​​will not start reading the original document M1. If the size item 44 is a card and the usage path is the first discharge path 19, the control unit 36 ​​will display a recommendation display 51 on the display unit 35 as shown in Figure 5. The user will check the recommendation display 51 and change the size item 44 or change the usage path to the second discharge path 20.

[0072] As shown in Figure 6, if the format item 46 is a single-page PDF and the usage path is the second discharge path 20, the control unit 36 ​​determines that the usage path is unsuitable for the reading setting. Therefore, if the reading setting indicates that it is a single-page PDF and the usage path is the second discharge path 20, the control unit 36 ​​displays the recommended display 51 on the display unit 35. Similarly, not limited to single-page PDFs, if the reading setting indicates that it is a single-page TIFF or a single-page PDF / A and the usage path is the second discharge path 20, the control unit 36 ​​displays the recommended display 51 on the display unit 35.

[0073] When the usage path is the second discharge path 20, the function of separating the original document M1 by the feed roller pair 28 is stopped, and only one original document M1 is read. When only one original document M1 is read, there is little need to separate the front and back sides of that original document M1 into separate files. Furthermore, if the reading item 47 is single-sided, the output result will not change whether it is a single-page PDF or a multi-page PDF. Therefore, in this case, the control unit 36 ​​does not need to display the recommended display 51 on the display unit 35.

[0074] If the format item 46 is a single-page PDF and the usage path is the second output path 20, there is no risk of damage to the original document M1. Therefore, in this case, the control unit 36 ​​displays the recommended display 51 shown in Figure 7 on the display unit 35.

[0075] As shown in Figure 7, the recommendation display 51 shows a YES button 52 and a NO button 53. If the YES button 52 is pressed, i.e., permission is obtained from the user, the control unit 36 ​​changes to the recommended reading settings. For example, if the format item 46 is a single-page PDF and the usage path is the second output path 20, the control unit 36 ​​changes the format item 46 from a single-page PDF to a multi-page PDF. If the NO button 53 is pressed, i.e., permission is not obtained from the user, the control unit 36 ​​starts reading the document M1 without changing the format item 46. In other words, the user can choose to change the reading settings or not change the reading settings by checking the recommendation display 51.

[0076] As shown in Figure 6, if the reading item 47 is double-sided and the usage path is the second discharge path 20, the control unit 36 ​​determines that the usage path is not suitable for the reading setting. Therefore, if the reading setting indicates that both sides of the document M1 should be read and the usage path is the second discharge path 20, the control unit 36 ​​displays the recommended display 51 on the display unit 35.

[0077] When the usage path is the second discharge path 20, the separation function of the original document M1 by the feed roller pair 28 is stopped, so only one original document M1 is read. When only one original document M1 is read, it is considered that there is little need to read both the front and back sides of that original document M1.

[0078] If the reading item 47 is double-sided and the usage path is the second output path 20, there is no risk of damage to the original document M1. Therefore, in this case, the control unit 36 ​​displays a recommended display 51 on the display unit 35, as shown in Figure 7. When the YES button 52 is pressed, the control unit 36 ​​changes the reading item 47 from double-sided to single-sided. When the NO button 53 is pressed, the control unit 36 ​​starts scanning the original document M1 without changing the reading item 47. In other words, the user can choose to change the scanning setting or not change the scanning setting by checking the recommended display 51.

[0079] As shown in Figure 6, if the opening item 48 is vertically opening and the usage path is the second discharge path 20, the control unit 36 ​​determines that the usage path is not suitable for the reading setting. Therefore, if the opening item 48 is vertically opening and the usage path is the second discharge path 20, the control unit 36 ​​displays the recommended display 51 on the display unit 35.

[0080] When the usage path is the second discharge path 20, the function of separating the original document M1 by the feed roller pair 28 is stopped, so only one original document M1 is read. When only one original document M1 is read, closing the front and back sides of that original document M1 vertically is considered inconvenient. Note that when the reading item 47 is single-sided, only one side of the original document M1 is read, so the output result does not change whether it is opened vertically or horizontally. Therefore, in this case, the control unit 36 ​​does not need to display the recommended display 51 on the display unit 35.

[0081] If the opening item 48 is top-to-bottom opening and the usage path is the second output path 20, there is no risk of damage to the document M1. Therefore, in this case, the control unit 36 ​​displays a recommended display 51 on the display unit 35, as shown in Figure 7. When the YES button 52 is pressed, the control unit 36 ​​changes the opening item 48 from top-to-bottom opening to left-to-right opening. When the NO button 53 is pressed, the control unit 36 ​​starts scanning the document M1 without changing the opening item 48. In other words, the user can choose to change the scanning settings or not change the scanning settings by checking the recommended display 51.

[0082] As shown in Figure 6, when the edge-clearing item 49 is OFF and the usage path is the second discharge path 20, the control unit 36 ​​determines that the usage path is not suitable for the reading setting. Therefore, when the reading setting indicates that edge-clearing should not be performed and the usage path is the second discharge path 20, the control unit 36 ​​displays the recommendation display 51 on the display unit 35.

[0083] If the usage path is the second discharge path 20, there is a possibility that a thick document M1 may be supplied to the scanner 11. When a thick document M1 is scanned, the shadow of the document M1 is likely to be reflected on the edges of the image data.

[0084] If the edge-erasure item 49 is OFF and the usage path is the second output path 20, there is no risk of damage to the original document M1. Therefore, in this case, the control unit 36 ​​displays a recommended display 51 on the display unit 35, as shown in Figure 7. When the YES button 52 is pressed, the control unit 36 ​​changes the edge-erasure item 49 from OFF to ON. When the NO button 53 is pressed, the control unit 36 ​​starts scanning the original document M1 without changing the edge-erasure item 49. In other words, the user can choose to change the scanning settings or not change the scanning settings by checking the recommended display 51.

[0085] As shown in Figure 6, if the blank page removal item 50 is ON and the usage path is the second discharge path 20, the control unit 36 ​​determines that the usage path is not suitable for the reading setting. Therefore, if the reading setting indicates that blank page removal should be performed and the usage path is the second discharge path 20, the control unit 36 ​​displays the recommendation display 51 on the display unit 35.

[0086] When the usage path is the second discharge path 20, the separation function of the original document M1 by the feed roller pair 28 is stopped, so only one original document M1 is read. When only one original document M1 is read, the possibility of blank pages being included in the image data is small.

[0087] If the blank page removal item 50 is ON and the usage path is the second output path 20, there is no risk of damage to the original document M1. Therefore, in this case, the control unit 36 ​​displays a recommended display 51 on the display unit 35 as shown in Figure 7. When the YES button 52 is pressed, the control unit 36 ​​changes the blank page removal item 50 from ON to OFF. When the NO button 53 is pressed, the control unit 36 ​​starts scanning the original document M1 without changing the blank page removal item 50. In other words, the user can choose to change the scanning settings or not change the scanning settings by checking the recommended display 51.

[0088] As described above, the control unit 36 ​​prompts the user to change the scanning settings or the scanning path if the scanning settings and the scanning path are incompatible and there is a risk of damaging the original document M1. The control unit 36 ​​prompts the user to change the scanning settings if the scanning settings and the scanning path are incompatible and there is no risk of damaging the original document M1. If there are multiple incompatible scanning settings and scanning paths, the user may be prompted to change each one sequentially, or they may be prompted to change all at once with a single recommendation display 51.

[0089] The control unit 36 ​​stores, for example, table data in the storage unit 37 that shows unsuitable combinations of reading settings and usage paths. The control unit 36 ​​may also store table data in the storage unit 37 that shows suitable combinations of reading settings and usage paths. By referring to this table data, the control unit 36 ​​determines whether or not a usage path is suitable for a given reading setting.

[0090] As shown in Figures 8 and 9, the display unit 35 displays a list screen 55. In this example, the list screen 55 will be described as the example shown in Figure 8 and the example shown in Figure 9. The display unit 35 displays the list screen 55, for example, when the home screen is operated. The control unit 36 ​​displays the list screen 55 on the display unit 35 based on the user's operation. The list screen 55 is a screen that displays a list of reading settings arbitrarily registered by the user. That is, the list screen 55 displays a list of multiple registered reading settings. For example, the home button 56 is displayed on the list screen 55. When the home button 56 is operated, the display unit 35 displays the home screen.

[0091] The list screen 55 displays multiple setting labels 57. Setting labels 57 are labels used to retrieve reading settings arbitrarily set by the user. In other words, when a setting label 57 is manipulated, the reading settings associated with that setting label 57 are read from the storage unit 37.

[0092] As shown in Figure 8, multiple setting labels 57 may be displayed in a list on the list screen 55. In Figure 8, multiple setting labels 57 are arranged vertically in two columns on the list screen 55.

[0093] The control unit 36 ​​may acquire route information when displaying the list screen 55 on the display unit 35. The control unit 36 ​​rearranges the multiple setting labels 57 based on the route information. For example, the control unit 36 ​​rearranges the setting labels 57 that indicate the appropriate reading settings for the route used, as indicated by the route information, so that they are displayed at the top. For example, if the route used is the first discharge route 19, the control unit 36 ​​displays the setting labels 57 where the size item 44 is A4 paper, B5 paper, etc., at the top, and the setting labels 57 where the size item 44 is card, booklet, etc., at the bottom. This makes it easier for the user to see the setting label 57 that indicates the appropriate reading settings for the route used. The user can select the setting label 57 that indicates the appropriate reading settings for the route used without scrolling the list screen 55.

[0094] As shown in Figure 9, in the list screen 55, multiple setting labels 57 may be displayed as tabs. In Figure 9, multiple tabs 58 are displayed in the list screen 55. For example, six setting labels 57 are displayed in each tab 58.

[0095] The control unit 36 ​​may acquire route information when displaying the list screen 55 on the display unit 35. The control unit 36 ​​displays a warning display 59 on the list screen 55 for reading settings that are unsuitable for the route used, as indicated by the route information. Specifically, the control unit 36 ​​displays a warning display 59 on the setting label 57 that indicates a reading setting unsuitable for the route used. The warning display 59 is, for example, a warning icon. This makes the setting label 57 that indicates a reading setting unsuitable for the route used more visible to the user.

[0096] As shown in Figures 8 and 9, a new button 60 is displayed on the list screen 55. The new button 60 is used to register a new setting label 57. When the new button 60 is pressed, a screen for registering the reading settings is displayed on the display unit 35. The new button 60 is displayed, for example, alongside the setting label 57 on the list screen 55.

[0097] As shown in Figure 10, when the new button 60 is pressed on the list screen 55, the display unit 35 displays the registration screen 61. The registration screen 61 is a screen for registering reading settings arbitrarily set by the user. The control unit 36 ​​displays the registration screen 61 on the display unit 35 based on the user's operation.

[0098] The registration screen 61 displays multiple setting items 43, similar to the settings screen 41. For example, the registration screen 61 displays items such as size 44, lamination 45, format 46, scan 47, opening 48, border removal 49, and blank page removal 50.

[0099] The registration screen 61 displays a registration button 62. When the registration button 62 is pressed, the reading settings configured on the registration screen 61 are registered. The contents of the registered reading settings are stored in the storage unit 37. Once the reading settings are registered, a setting label 57 is added to the list screen 55.

[0100] The control unit 36 ​​may acquire route information when displaying the registration screen 61 on the display unit 35. The control unit 36 ​​may also display the reading settings appropriate for the route used as indicated by the route information as the initial value on the registration screen 61. For example, if the route used is the first discharge route 19, OFF may be displayed as the initial value for the lamination item 45. Figure 11 shows the initial values ​​for several setting items 43 displayed on the registration screen 61.

[0101] As shown in Figure 11, when the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the size item 44 to automatic detection, for example. When the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the lamination item 45 to OFF, for example. When the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the format item 46 to single-page PDF or single-page TIFF, for example. When the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the read item 47 to double-sided, for example. When the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the open item 48 to top and bottom open, for example. When the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the border removal item 49 to OFF, for example. When the usage path is the first output path 19, the control unit 36 ​​sets the initial value of the blank page removal item 50 to ON, for example.

[0102] If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the size item 44 to, for example, card. If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the lamination item 45 to, for example, ON. If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the format item 46 to, for example, multi-page PDF or multi-page TIFF. If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the read item 47 to, for example, single-sided. If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the open item 48 to, for example, left-right opening. If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the border removal item 49 to, for example, ON. If the usage path is the second discharge path 20, the control unit 36 ​​sets the initial value of the blank page removal item 50 to, for example, OFF.

[0103] The control unit 36 ​​sets initial values ​​for multiple setting items 43, so the user does not need to configure all setting items 43, but only needs to operate on the necessary setting items 43. This improves convenience.

[0104] The control unit 36 ​​stores table data in the storage unit 37 that shows the initial values ​​for each of the multiple setting items 43. The control unit 36 ​​refers to this table data to set the initial values ​​for the multiple setting items 43 when displaying the registration screen 61 on the display unit 35.

[0105] As shown in Figures 12 and 13, the control unit 36 ​​may display the recommended display 51 on the display unit 35 by comparing the reading settings set on the registration screen 61 with the route information. The control unit 36 ​​compares the reading settings with the route information when, for example, the registration button 62 is operated. If the control unit 36 ​​determines that the route indicated by the route information is suitable for the reading settings, it registers the reading settings. If the control unit 36 ​​determines that the route is not suitable for the reading settings, it displays the recommended display 51 on the display unit 35. For example, the control unit 36 ​​displays the recommended display 51 on the display unit 35 so that it overlaps with the registration screen 61.

[0106] The control unit 36 ​​may display the recommended display 51 not only when the registration button 62 is operated, but also while the reading settings are being set on the registration screen 61. That is, the control unit 36 ​​may compare the reading settings with the route information while the reading settings are being set on the registration screen 61. The control unit 36 ​​may also compare the reading settings with the route information when the setting for setting item 43 is changed, that is, when the reading settings are changed. For example, if the route used is the second discharge route 20, and the reading item 47 is changed from single-sided to double-sided on the registration screen 61, the control unit 36 ​​will display the recommended display 51 on the display unit 35. Note that "while the reading settings are being set on the registration screen 61" may refer to the period from when the registration screen 61 is displayed on the display unit 35 until the user completes registering the reading settings. For example, "while the reading settings are being registered on the registration screen 61" includes the period from when the display on the display unit 35 transitions from the list screen 55 to the registration screen 61 until the registration button 62 is operated. For example, "while the reading settings are being registered" on the registration screen 61 includes the timing when setting item 43 is operated on the registration screen 61.

[0107] As shown in Figure 12, if the combination of scanning settings and the path used is unsuitable and there is a risk of damage to the original document M1, the control unit 36 ​​displays a recommendation message 51 on the display unit 35. If there is a risk of damage to the original document M1, the control unit 36 ​​prohibits registration with those scanning settings. The control unit 36 ​​prompts the user to change the scanning settings with the recommendation message 51.

[0108] As shown in Figure 13, if the combination of scanning settings and the path used is unsuitable and there is no risk of damage to the original document M1, the control unit 36 ​​displays a recommended display 51 on the display unit 35. If there is no risk of damage to the original document M1, the control unit 36 ​​prompts the user to change the scanning settings. If the YES button 52 is pressed, the control unit 36 ​​changes to the recommended scanning settings. If the NO button 53 is pressed, the control unit 36 ​​registers the scanning settings without changing them.

[0109] <Flowchart> Next, the processes performed by the control unit 36 ​​will be described. The control unit 36 ​​performs setting, sorting, warning, and registration processes by executing program 38.

[0110] First, let's explain the setting process. When the start button 42 is pressed on the setting screen 41, the control unit 36 ​​executes the setting process shown in Figure 14. The control unit 36 ​​may also execute the setting process when the reading setting is changed on the setting screen 41.

[0111] As shown in Figure 14, in step S10, the control unit 36 ​​acquires route information. At this time, the control unit 36 ​​acquires route information from the first route sensor 23 and the second route sensor 24.

[0112] In step S11, the control unit 36 ​​acquires the reading settings. At this time, the control unit 36 ​​acquires the reading settings set on the setting screen 41. In step S12, the control unit 36 ​​determines whether the route used is suitable for the reading setting. At this time, the control unit 36 ​​determines whether the route used is suitable for the reading setting based on the route information obtained in step S11 and the reading setting obtained in step S12. If the control unit 36 ​​determines that the route used is suitable for the reading setting, it proceeds to step S13. If the control unit 36 ​​determines that the route used is not suitable for the reading setting, it proceeds to step S15.

[0113] In step S13, the control unit 36 ​​determines whether or not to start scanning the document M1. At this time, the control unit 36 ​​determines, for example, whether or not the trigger for starting the setting process was the operation of the start button 42. If the control unit 36 ​​determines that the setting process was started by the operation of the start button 42, it proceeds to step S14. If the control unit 36 ​​determines that the setting process was started by, for example, a change in the scanning settings, it terminates the setting process.

[0114] In step S14, the control unit 36 ​​starts reading the document M1. At this time, the control unit 36 ​​reads the document M1 based on the reading settings acquired in step S11. When the reading of the document M1 is complete, the control unit 36 ​​terminates the setting process.

[0115] In step S15, the control unit 36 ​​determines whether or not there is a risk of damage to the document M1. At this time, the control unit 36 ​​determines whether or not there is a risk of damage to the document M1 due to an inappropriate combination of scanning settings and the path used. If the control unit 36 ​​determines that there is a risk of damage to the document M1, it proceeds to step S16. If the control unit 36 ​​determines that there is no risk of damage to the document M1, it proceeds to step S17.

[0116] In step S16, the control unit 36 ​​displays a recommendation display 51. At this time, because there is a risk of damage to the document M1, the control unit 36 ​​displays a recommendation display 51 as shown in Figure 5. After completing the process in step S16, the control unit 36 ​​terminates the setting process. This is because, if there is a risk of damage to the document M1, reading of the document M1 is prohibited until the reading settings or usage path is changed.

[0117] In step S17, the control unit 36 ​​displays the recommendation display 51. At this time, since there is no risk of damage to the original document M1, the control unit 36 ​​displays the recommendation display 51 having a YES button 52 and a NO button 53, as shown in Figure 7.

[0118] In step S18, the control unit 36 ​​determines whether or not to change to the recommended reading settings. At this time, the control unit 36 ​​determines whether the YES button 52 or the NO button 53 was operated. If the YES button 52 was operated, the control unit 36 ​​determines to change to the recommended reading settings. In this case, the control unit 36 ​​proceeds to step S19. If the NO button 53 was operated, the control unit 36 ​​determines not to change to the recommended reading settings. In this case, the control unit 36 ​​proceeds to step S13.

[0119] In step S19, the control unit 36 ​​changes to the recommended reading settings. After changing to the recommended reading settings, the control unit 36 ​​proceeds to step S13. As described above, the control method for the reading device 11 includes acquiring route information indicating the route used. The control method for the reading device 11 also includes displaying the recommended display 51 based on the reading settings and route information.

[0120] Next, the sorting process will be explained. When the control unit 36 ​​displays the list screen 55, which displays the setting labels 57, on the display unit 35, it executes the sorting process shown in Figure 15.

[0121] As shown in Figure 15, in step S20, the control unit 36 ​​acquires route information. At this time, the control unit 36 ​​acquires route information from the first route sensor 23 and the second route sensor 24.

[0122] In step S21, the control unit 36 ​​acquires the reading settings for the setting label 57. That is, in step S21, the control unit 36 ​​acquires the contents of the reading settings associated with the setting label 57.

[0123] In step S22, the control unit 36 ​​determines whether the reading setting is appropriate for the route being used. At this time, the control unit 36 ​​compares the route information obtained in step S20 with the reading setting obtained in step S21. If the control unit 36 ​​determines that the reading setting is appropriate for the route being used, it proceeds to step S23. If the control unit 36 ​​determines that the reading setting is not appropriate for the route being used, it proceeds to step S25.

[0124] In step S23, the control unit 36 ​​places the setting label 57 at the top. More specifically, the control unit 36 ​​places the setting label 57, which is associated with a reading setting suitable for the usage route, at the top of the list screen 55.

[0125] In step S24, the control unit 36 ​​determines whether it has made a determination for all setting labels 57. If the control unit 36 ​​determines that it has made a determination for all setting labels 57, it terminates the sorting process. If the control unit 36 ​​determines that it has not made a determination for all setting labels, it returns to step S21.

[0126] In step S25, the control unit 36 ​​places the setting label 57 at the bottom. Specifically, the control unit 36 ​​places the setting label 57 associated with a reading setting unsuitable for the usage path at the bottom of the list screen 55. After completing the processing in step S25, the control unit 36 ​​moves on to step S24.

[0127] Next, the warning process will be explained. When the control unit 36 ​​displays a list screen 55 that displays the setting labels 57 in tabs on the display unit 35, it executes the warning process shown in Figure 16. As shown in Figure 16, in step S30, the control unit 36 ​​acquires route information. At this time, the control unit 36 ​​acquires route information from the first route sensor 23 and the second route sensor 24.

[0128] In step S31, the control unit 36 ​​acquires the reading settings for the setting label 57. That is, in step S31, the control unit 36 ​​acquires the contents of the reading settings associated with the setting label 57.

[0129] In step S32, the control unit 36 ​​determines whether the reading setting is appropriate for the route being used. At this time, the control unit 36 ​​compares the route information obtained in step S30 with the reading setting obtained in step S31. If the control unit 36 ​​determines that the reading setting is appropriate for the route being used, it proceeds to step S33. If the control unit 36 ​​determines that the reading setting is not appropriate for the route being used, it proceeds to step S34.

[0130] In step S33, the control unit 36 ​​determines whether it has made a determination for all setting labels 57. If the control unit 36 ​​determines that it has made a determination for all setting labels 57, it terminates the warning process. If the control unit 36 ​​determines that it has not made a determination for all setting labels 57, it proceeds to step S31.

[0131] In step S34, the control unit 36 ​​displays a warning display 59 on the setting label 57. Specifically, the control unit 36 ​​displays a warning display 59 on the setting label 57 that is associated with a reading setting unsuitable for the usage path. After completing the processing in step S34, the control unit 36 ​​proceeds to step S33.

[0132] Next, the registration process will be explained. When the registration screen 61 is displayed, the control unit 36 ​​executes the registration process shown in Figure 17. When the registration screen 61 is displayed, the list screen 55 is already displayed, so the control unit 36 ​​has already acquired the route information.

[0133] As shown in Figure 17, in step S40, the control unit 36 ​​sets an initial value suitable for the route to be used. At this time, the control unit 36 ​​sets an initial value suitable for the route to be used indicated by the route information already acquired to the setting item 43 on the registration screen 61.

[0134] In step S41, the control unit 36 ​​determines whether the registration button 62 has been operated or whether the reading setting has been changed. If the control unit 36 ​​determines that the registration button 62 has been operated or that the reading setting has been changed, it proceeds to step S42. If the control unit 36 ​​determines that the registration button 62 has not been operated and the reading setting has not been changed, it repeats the process in step S41. In other words, the control unit 36 ​​proceeds from step S41 to step S42 when the registration button 62 is operated or the reading setting is changed.

[0135] In step S42, the control unit 36 ​​determines whether the route used is suitable for the reading setting. At this time, the control unit 36 ​​compares the route used indicated by the route information already acquired with the reading setting set on the registration screen 61. If the control unit 36 ​​determines that the route used is suitable for the reading setting, it proceeds to step S43. If the control unit 36 ​​determines that the route used is not suitable for the reading setting, it proceeds to step S45.

[0136] In step S43, the control unit 36 ​​determines whether the registration button 62 has been operated. At this time, the control unit 36 ​​determines in step S41 whether the registration button 62 was operated. If the control unit 36 ​​determines that the registration button 62 has been operated, it proceeds to step S44. If the control unit 36 ​​determines that the registration button 62 has not been operated, it returns to step S41.

[0137] In step S44, the control unit 36 ​​registers the reading settings. As a result, a setting label 57 is added to the list screen 55. After completing the process in step S44, the control unit 36 ​​terminates the registration process.

[0138] In step S45, the control unit 36 ​​determines whether there is a risk of damage to the document M1. At this time, the control unit 36 ​​determines whether there is a risk of damage to the document M1 due to an inappropriate combination of scanning settings and the path used. If the control unit 36 ​​determines that there is a risk of damage to the document M1, it proceeds to step S46. If the control unit 36 ​​determines that there is no risk of damage to the document M1, it proceeds to step S47.

[0139] In step S46, the control unit 36 ​​displays a recommendation display 51. At this time, because there is a risk of damage to the original document M1, the control unit 36 ​​displays a recommendation display 51 as shown in Figure 12. After completing the process in step S46, the control unit 36 ​​returns to step S41. This is because, if there is a risk of damage to the original document M1, the registration of the scanning settings is prohibited.

[0140] In step S47, the control unit 36 ​​displays a recommendation display 51. At this time, since there is no risk of damaging the original document M1, the control unit 36 ​​displays a recommendation display 51 having a YES button 52 and a NO button 53, as shown in Figure 13.

[0141] In step S48, the control unit 36 ​​determines whether to change to the recommended reading settings. At this time, the control unit 36 ​​determines whether the YES button 52 or the NO button 53 was operated. If the YES button 52 was operated, the control unit 36 ​​determines to change to the recommended reading settings. In this case, the control unit 36 ​​proceeds to step S49. If the NO button 53 was operated, the control unit 36 ​​determines not to change to the recommended reading settings. In this case, the control unit 36 ​​proceeds to step S43.

[0142] In step S49, the control unit 36 ​​changes to the recommended reading settings. After changing to the recommended reading settings, the control unit 36 ​​proceeds to step S43. <Mechanism and Effects> Next, the operation and effects of the above embodiment will be described.

[0143] (1) The control unit 36 ​​acquires route information indicating the route used and, based on the reading settings and route information, displays a recommendation display 51 on the display unit 35 prompting the user to change the reading settings or to change the route used.

[0144] According to the above configuration, the control unit 36 ​​displays a recommendation display 51 on the display unit 35, for example, if the usage path is not suitable for the reading setting. By checking the recommendation display 51, the user can understand the usage path suitable for the reading setting, or the reading setting suitable for the usage path. By changing the reading setting or usage path according to the content of the recommendation display 51, the original document M1 is ejected through the usage path suitable for the reading setting.

[0145] (2) The control unit 36 ​​receives an instruction to start reading the document M1, compares the reading settings with the route information, and if it determines that the route used is not suitable for the reading settings, it displays a recommendation 51 on the display unit 35.

[0146] With the above configuration, the recommended display 51 can be displayed on the display unit 35 before the scanning of the document M1 begins. In this case, compared to when the recommended display 51 is displayed after the scanning of the document M1 is completed, the user can be prompted to change the scanning settings or the usage path at an earlier stage.

[0147] (3) The control unit 36 ​​compares the reading settings with the route information while the reading settings are being configured on the setting screen 41, and if it determines that the route being used is not suitable for the reading settings, it displays a recommended display 51 on the display unit 35.

[0148] With the above configuration, the recommended display 51 can be displayed on the display unit 35 while the reading settings are being configured. In this case, compared to when the recommended display 51 is displayed after the reading settings have been configured, the user can be prompted to change the reading settings or the usage path at an earlier stage.

[0149] (4) The control unit 36 ​​displays a registration screen 61 for registering the reading settings on the display unit 35. While the reading settings are being set on the registration screen 61, the control unit 36 ​​compares the reading settings with the route information and, if it determines that the route used is not suitable for the reading settings, displays a recommendation display 51 on the display unit 35.

[0150] With the above configuration, the recommended display 51 can be displayed while the reading settings are being configured on the registration screen 61. In this case, compared to when the recommended display 51 is displayed after the reading settings have been configured on the registration screen 61, the user can be prompted to change the reading settings or usage path at an earlier stage.

[0151] (5) When the control unit 36 ​​displays the registration screen 61 on the display unit 35, it displays the reading settings appropriate for the route information as initial values ​​on the registration screen 61. According to the above configuration, the registration screen 61 displays the reading settings suitable for the current usage route as the initial value, thereby improving the usability of the registration screen 61.

[0152] (6) The control unit 36 ​​displays a list screen 55 on the display unit 35 that shows a list of multiple registered reading settings. Based on the route information, the control unit 36 ​​changes the order of the multiple reading settings displayed on the list screen 55.

[0153] According to the above configuration, among the multiple registered reading settings, the reading setting most suitable for the current usage route is preferentially displayed on the list screen 55. This makes it easier for the user to select the reading setting most suitable for their usage route.

[0154] (7) The control unit 36 ​​displays a list screen 55 on the display unit 35 that shows a list of multiple registered reading settings. The control unit 36 ​​displays a warning 59 on the list screen 55 for reading settings that are unsuitable for the route used as indicated by the route information.

[0155] According to the above configuration, among the multiple registered reading settings, any reading settings that are not suitable for the current usage route will display a warning message 59 on the list screen 55. This allows the user to avoid reading settings that are not suitable for the usage route.

[0156] (8) The reading settings include a setting item 43 that indicates whether or not the original document M1 is laminated. The control unit 36 ​​displays a recommended display 51 on the display unit 35 when the reading settings indicate that the original document M1 is laminated and the usage path is the first discharge path 19.

[0157] If the original document M1 is laminated, it may be damaged by bending. Therefore, if the original document M1 is laminated, it is preferable that it be discharged through the second discharge path 20.

[0158] With the above configuration, the risk of the laminated document M1 being ejected through the first ejection path 19 is reduced. The user can switch the ejection path from the first ejection path 19 to the second ejection path 20, for example, by looking at the recommended display 51. This ensures that the document M1 is ejected through a path suitable for the scanning settings.

[0159] (9) The reading settings include a setting item 43 that indicates whether the document M1 is a card or a booklet. The control unit 36 ​​displays a recommended display 51 on the display unit 35 when the reading settings indicate that the document M1 is a card or a booklet and the usage path is the first discharge path 19.

[0160] If the original document M1 is a card, it may be damaged by bending. If the original document M1 is a booklet, it may get jammed by bending. Therefore, if the original document M1 is a card or a booklet, it is preferable that it be discharged through the second discharge path 20.

[0161] With the above configuration, the risk of the original document M1, which is a card or booklet, being ejected through the first ejection path 19 is reduced. The user can switch the ejection path from the first ejection path 19 to the second ejection path 20, for example, by looking at the recommended display 51. This ensures that the original document M1 is ejected through a path suitable for the scanning settings.

[0162] (10) The reading setting includes a setting item 43 indicating whether or not to read both sides of the original document M1. The control unit 36 ​​displays a recommended display 51 on the display unit 35 when the reading setting indicates that both sides of the original document M1 will be read and the usage path is the second discharge path 20.

[0163] For example, if the original document M1 is laminated, it may be damaged by bending. For example, if the original document M1 is a card, it may be damaged by bending. For example, if the original document M1 is a booklet, it may get jammed by bending. Therefore, it is preferable that such original documents M1 be discharged through the second discharge path 20. Consequently, there are restrictions on the type of original document M1 for the first discharge path 19. On the other hand, there are no restrictions on the type of original document M1 for the second discharge path 20.

[0164] When the original document M1 is laminated, a card, or a booklet, it is often unnecessary to scan both sides of it, compared to when the original document M1 is on regular paper. With the above configuration, the risk of scanning both sides of the original document M1 when scanning a document suitable for the second output path 20 is reduced.

[0165] (11) The reading setting includes a setting item 43, i.e., a first setting item, which indicates whether or not to perform a predetermined image processing on the image data of the original document M1 read by the reading unit 31. The control unit 36 ​​compares the reading setting, including the first setting item, with the route information, and if it determines that the route used is unsuitable for the first setting item, it displays a recommendation display 51 on the display unit 35. With the above configuration, image processing is performed appropriately according to the route used.

[0166] (12) The reading settings include a setting item 43, i.e., a second setting item, which indicates the format in which the image data of the document M1 read by the reading unit 31 will be output. The control unit 36 ​​compares the reading settings, including the second setting item, with the route information, and if it determines that the route used is not suitable for the second setting item, it displays a recommendation 51 on the display unit 35. With the above configuration, the image data is output in an appropriate format according to the route used.

[0167] (13) The discharge path switches to the first discharge path 19 when the housing 12 is in the first orientation, and to the second discharge path 20 when the housing 12 is in the second orientation. According to the above configuration, the usage path switches in conjunction with the orientation of the housing 12. Therefore, the user can easily switch between usage paths.

[0168] <Example of changes> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0169] Program 38 may be installed, for example, on computer 39. For example, computer 39 may control the reader 11. Program 38 can cause computer 39 to perform the following actions: obtain route information from reader 11, and display a recommended display 51 based on the reading settings and route information. In this case, computer 39, which is an external device, and reader 11 constitute an image reading system. Computer 39 also functions as an external control unit. Therefore, computer 39 has an external control unit. The external control unit obtains route information and reading settings from reader 11. The external control unit displays a recommended display 51 based on the reading settings and route information. In this case, the external control unit may display the recommended display 51 on a device other than reader 11 and the external device.

[0170] The reading device 11 may include a drive unit for changing the orientation of the housing 12. The drive unit is, for example, a motor. The drive unit rotates the housing 12 by driving it. This switches the orientation of the housing 12. The orientation of the housing 12 is automatically switched by the drive unit.

[0171] The reading device 11 may be configured to allow the usage path to be changed via the setting screen 41. In this case, the control unit 36 ​​switches the usage path. For example, the control unit 36 ​​switches the usage path by displacing the switching member 22 with a drive unit such as a motor.

[0172] <Technical philosophy> The technical concepts and their effects that can be understood from the embodiments and modifications described above are described below.

[0174] According to the above configuration, the control unit displays a recommendation on the display unit if, for example, the usage path is unsuitable for the reading settings. By checking the recommendation, the user can understand the usage path suitable for the reading settings, or the reading settings suitable for the usage path. By changing the reading settings or usage path according to the content of the recommendation, the document is ejected through the usage path suitable for the reading settings.

[0175] (B) In the above-mentioned reading device, the control unit may compare the reading settings with the route information upon receiving an instruction to start reading the document, and if it determines that the route used is unsuitable for the reading settings, it may display the recommended display on the display unit.

[0176] With the above configuration, a recommended display can be shown on the display unit before the document scanning begins. In this case, compared to when the recommended display is shown after the document scanning is complete, the user can be prompted to change the scanning settings or usage path at an earlier stage.

[0177] (C) In the above-described reading device, the control unit may compare the reading setting with the route information while the reading setting is being set on the setting screen, and if it determines that the route used is unsuitable for the reading setting, it may display the recommended display on the display unit.

[0178] With the above configuration, a recommended display can be shown on the display unit while the reading settings are being configured. In this case, compared to when the recommended display is shown after the reading settings have been configured, the user can be prompted to change the reading settings or usage path at an earlier stage.

[0179] (D) In ​​the above-mentioned reading device, the control unit may display a registration screen for registering the reading settings on the display unit, compare the reading settings with the route information while the reading settings are being set on the registration screen, and if it determines that the route used is not suitable for the reading settings, it may display the recommendation display on the display unit.

[0180] With the above configuration, recommended displays can be shown while the reading settings are being configured on the registration screen. In this case, compared to when recommended displays are shown after the reading settings have been configured on the registration screen, it is possible to prompt the user to change the reading settings or usage path at an earlier stage.

[0181] (E) In the above reading device, when the control unit displays the registration screen on the display unit, it may display the reading settings suitable for the route information as initial values ​​on the registration screen. With the above configuration, the reading settings suitable for the currently used route are displayed as initial values ​​on the registration screen, thus improving the usability of the registration screen.

[0182] (F) In the above-mentioned reading device, the control unit may cause the display unit to display a list screen that shows a list of the registered reading settings, and may change the order of the multiple reading settings displayed on the list screen based on the route information.

[0183] With the above configuration, among the multiple registered reading settings, the reading setting most suitable for the current usage route is displayed preferentially on the list screen. This makes it easier for the user to select the reading setting appropriate for their usage route.

[0184] (G) In the above-mentioned reading device, the control unit may cause the display unit to display a list screen that shows a list of the registered reading settings, and may display a warning on the list screen for any reading settings that are unsuitable for the route used as indicated by the route information.

[0185] With the above configuration, any reading settings among the registered settings that are unsuitable for the current usage route will be displayed as a warning on the list screen. This allows users to avoid using reading settings that are unsuitable for their usage route.

[0186] (H) In the above-described reading device, the first discharge path is a path through which the document is discharged while curved, the second discharge path is a path through which the document is discharged without curving, the reading setting includes a setting item indicating whether or not the document is laminated, and the control unit may display the recommended display on the display unit when the reading setting indicates that the document is laminated and the path used is the first discharge path.

[0187] If the document is laminated, it may be damaged by bending. Therefore, if the document is laminated, it is preferable that it be discharged through the second discharge path.

[0188] With the above configuration, the risk of laminated documents being ejected through the first ejection path is reduced. The user can switch the ejection path from the first to the second by, for example, viewing the recommended display. This ensures that the document is ejected through the path suitable for the scanning settings.

[0189] (I) In the above-mentioned reading device, the first discharge path is a path through which the document is discharged while curved, the second discharge path is a path through which the document is discharged without curving, the reading setting includes a setting item indicating whether or not the document is a card or a booklet, and the control unit may display the recommended display on the display unit when the reading setting indicates that the document is a card or a booklet and the path used is the first discharge path.

[0190] If the document is a card, it may be damaged by bending. If the document is a booklet, it may jam due to bending. Therefore, if the document is a card or a booklet, it is preferable that it be discharged through the second discharge path.

[0191] With the above configuration, the risk of a document, whether a card or booklet, being ejected through the first ejection path is reduced. The user can switch the ejection path from the first to the second by, for example, viewing a recommended display. This ensures that the document is ejected through the path suitable for the scanning settings.

[0192] (J) In the above-described reading device, the first discharge path is a path through which the document is discharged while curved, the second discharge path is a path through which the document is discharged without curving, the reading setting includes a setting item indicating whether or not to read both sides of the document, and the control unit may display the recommended display on the display unit when the reading setting indicates that both sides of the document will be read and the path used is the second discharge path.

[0193] For example, if a document is laminated, it may be damaged by bending. For example, if a document is a card, it may be damaged by bending. For example, if a document is a booklet, it may get jammed by bending. Therefore, it is preferable that such documents be discharged through the second discharge path. Consequently, there are restrictions on the type of document that can be discharged through the first discharge path. On the other hand, there are no restrictions on the type of document that can be discharged through the second discharge path.

[0194] When the original document is laminated, a card, or a booklet, it is often unnecessary to scan both sides compared to when the original document is on regular paper. With the above configuration, the risk of scanning both sides of the original document is reduced when scanning a document suitable for the second output path.

[0195] (K) In the above-described reading device, the first discharge path is a path through which the document is discharged while curved, the second discharge path is a path through which the document is discharged without curving, the reading setting includes a first setting item indicating whether or not to perform predetermined image processing on the image data of the document read by the reading unit, and the control unit may compare the first setting item with the path information and, if it determines that the path used is unsuitable for the first setting item, display the recommendation on the display unit. With the above configuration, image processing is performed appropriately according to the path used.

[0196] (L) In the above-described reading device, the first discharge path is a path through which the document is discharged while curved, the second discharge path is a path through which the document is discharged without curving, the reading setting includes a second setting item that indicates the format in which the image data of the document read by the reading unit is output, and the control unit may compare the second setting item with the path information and, if it determines that the path used is unsuitable for the second setting item, display the recommended display on the display unit. With the above configuration, the image data is output in an appropriate format according to the path used.

[0197] (M) The reading device comprises a housing that houses the reading unit and a support unit that supports the housing. The housing is configured to be switchable between a first position and a second position, each having a different inclination angle with respect to the mounting surface on which the support unit is installed. The usage path may switch to the first discharge path when the housing is in the first position, and to the second discharge path when the housing is in the second position. With this configuration, the usage path switches in conjunction with the position of the housing. Therefore, the user can easily switch the usage path.

[0198] (N) A control method for a reading device is a control method for a reading device configured to switch between a first discharge path and a second discharge path for the discharge of a document read by the reading unit, and includes acquiring path information indicating the use path, and displaying a recommendation prompting the user to change the reading settings or the use path based on the reading settings related to document reading and the path information. The above configuration provides the same effects as the reading device described above.

[0199] (O) The program controls a reading device configured to switch between a first discharge path and a second discharge path for the discharge of documents read by the reading unit, and causes the computer to perform the following actions: acquire path information indicating the use path, and display a recommendation prompting the computer to change the reading settings or the use path based on the reading settings related to document reading and the path information.
