The control device 12 is, for example, a personal computer, a smart phone, a tablet computer, etc. In the image reading system 11, the control device 12 may also store a driver for controlling the image reading device 13. In the image reading system 11, the image reading device 13 may also operate independently.

[0033] Control device

[0034] The control device 12 includes an operation unit. Specifically, the control device 12 includes a terminal operation unit 14. The terminal operation unit 14 is operated by a user. The user operates the control device 12 through the terminal operation unit 14. The terminal operation unit 14 is, for example, a touch panel. The terminal operation unit 14 is not limited to a touch panel and may also be a button, a lever, etc.

[0035] The control device 12 includes a display unit. Specifically, the control device 12 includes a terminal display unit 15. The terminal display unit 15 displays a screen. Specifically, the terminal display unit 15 displays a screen for operating the image reading device 13. The user issues an instruction to the image reading device 13 through the screen displayed on the terminal display unit 15.

[0036] The control device 12 includes a control unit. Specifically, the control device 12 includes a terminal control unit 16. The terminal control unit 16 controls the terminal display unit 15. The terminal control unit 16 performs control so that the terminal display unit 15 displays a screen. The terminal control unit 16 is configured to communicate with the image reading device 13. The terminal control unit 16 sends an instruction input through the screen displayed on the terminal display unit 15 to the image reading device 13.

[0037] The terminal control unit 16 may also be composed of one or more processors that execute various processes according to a computer program. The terminal control unit 16 may also be composed of one or more dedicated hardware circuits such as an ASIC that executes at least a part of the various processes. The terminal control unit 16 may also be composed of a circuit including a combination of a processor and a hardware circuit. The processor includes a CPU and memories such as a RAM and a ROM. The memory stores program codes or instructions configured to cause the CPU to execute processes. The memory, i.e., the computer-readable medium, includes all readable media that can be accessed by a general-purpose or dedicated computer.

[0038] Image reading device

[0039] The image reading device 13 is configured to read a document M1. The image reading device 13 is, for example, a scanner that reads images such as characters and photos printed on a document M1 such as paper or film.

[0040] The image reading device 13 includes a housing 21.

[0041] The image reading device 13 includes a supply tray 22. A stack of original documents MA formed by stacking a plurality of original documents M1 is placed on the supply tray 22. The supply tray 22 extends from the housing 21. The supply tray 22 guides the original document M1 into the housing 21.

[0042] The image reading device 13 includes a conveying unit 23. The conveying unit 23 is configured to convey the original document M1. The conveying unit 23 conveys the original document M1 one by one from the stack of original documents MA. The conveying unit 23 conveys the original document M1 on the supply tray 22 into the housing 21. The conveying unit 23 discharges the original document M1 from the housing 21 to the outside of the housing 21.

[0043] The conveying unit 23 has a plurality of rollers. The conveying unit 23 has a pickup roller 24. The pickup roller 24 is a roller that conveys the original document M1 one by one from the stack of original documents MA. In one example, the pickup roller 24 contacts the lowermost original document M1 in the stack of original documents MA. The conveying unit 23 has one or more pairs of conveying rollers 25. The pairs of conveying rollers 25 rotate while clamping the original document M1. The conveying unit 23 may also have a delay roller that suppresses double feeding. Double feeding means that a plurality of original documents M1 are conveyed overlappingly. The delay roller rotates, for example, so that the original document M1 returns from the housing 21 to the supply tray 22.

[0044] The image reading device 13 includes a reading unit 26. The reading unit 26 is configured to read the original document M1. The reading unit 26 reads the conveyed original document M1. The reading unit 26 is composed of a plurality of optical sensors arranged in the main scanning direction. The reading unit 26 is, for example, a contact image sensor module. The reading unit 26 may be configured to read one side of the original document M1 or may be configured to read both sides.

[0045] The image reading device 13 includes a detection unit 27. The detection unit 27 is configured to detect the original document M1. The detection unit 27 is configured to detect at least one of the size of the original document M1 and the type of the original document M1. The detection unit 27 may be configured to detect the size of the original document M1, may be configured to detect the type of the original document M1, or may be configured to detect both. In one example, the detection unit 27 detects both the size of the original document M1 and the type of the original document M1.

[0046] The detection unit 27 has a size detection unit 28. The size detection unit 28 is configured to detect the size of the original document M1. The size detection unit 28 detects the size of the original document M1 in the main scanning direction and the size of the original document M1 in the sub-scanning direction.

[0047] The size detection unit 28 includes a main scanning detection unit 29. The main scanning detection unit 29 is configured to detect the size of the original document M1 in the main scanning direction. In one example, the main scanning detection unit 29 is composed of a plurality of optical sensors arranged in the main scanning direction. The size detection unit 28 detects the size of the original document M1 in the main scanning direction by detecting both side ends of the original document M1 by the main scanning detection unit 29. The main scanning detection unit 29 may also be composed of the reading unit 26.

[0048] The size detection unit 28 includes a sub-scanning detection unit 30. The sub-scanning detection unit 30 is configured to detect the size of the original document M1 in the sub-scanning direction. In one example, the sub-scanning detection unit 30 is composed of one optical sensor. The sub-scanning detection unit 30 detects the front end and the rear end of the original document M1. The size detection unit 28 detects the size of the original document M1 in the sub-scanning direction based on the conveyance amount of the conveyance unit 23 from when the front end of the original document M1 is detected by the sub-scanning detection unit 30 until the rear end of the original document M1 is detected.

[0049] The detection unit 27 includes a category detection unit 31. The category detection unit 31 is configured to detect the category of the original document M1. The category detection unit 31 is composed of an optical sensor. The category detection unit 31 irradiates light onto the original document M1 and receives the reflected light. The category detection unit 31 detects the category of the original document M1 based on the waveform of the reflected light. For example, when the original document M1 is high-quality paper, compared with the case where the original document M1 is ordinary paper, the waveform of the reflected light becomes uniform. When the original document M1 is recycled paper, compared with the case where the original document M1 is ordinary paper, the waveform of the reflected light is uneven. The category detection unit 31 may also include an ultrasonic sensor. In this case, the category detection unit 31 irradiates ultrasonic waves onto the original document M1. The category detection unit 31 detects the category of the original document M1 based on the attenuation rate of the ultrasonic waves. For example, when the original document M1 is thick paper, compared with the case where the original document M1 is ordinary paper, the attenuation rate of the ultrasonic waves becomes larger. In this way, the category detection unit 31 can detect categories such as high-quality paper, ordinary paper, recycled paper, and thick paper.

[0050] The image reading device 13 is provided with a double-feed detection unit 32. The double-feed detection unit 32 is configured to detect double-feeding of the original document M1. The double-feed detection unit 32 detects whether a plurality of original documents M1 are conveyed from the supply tray 22 in an overlapping state.

[0051] The double-feed detection unit 32 has an ultrasonic sensor. The double-feed detection unit 32 irradiates the original document M1 with ultrasonic waves. The double-feed detection unit 32 detects double-feeding based on the attenuation rate of the ultrasonic waves. For example, when double-feeding occurs, the attenuation rate of the ultrasonic waves becomes larger than when double-feeding does not occur. Thus, the double-feed detection unit 32 detects double-feeding. The double-feed detection unit 32 may also constitute the category detection unit 31. The double-feed detection unit 32 can detect the original document M1 of thick paper through the ultrasonic sensor. For example, when double-feeding occurs, the attenuation rate of the ultrasonic waves becomes larger than when the original document M1 is thick paper.

[0052] The image reading device 13 may also include a tray detection unit 33. The tray detection unit 33 is configured to detect the original document M1 placed on the supply tray 22. The tray detection unit 33 detects whether there is an original document M1 placed on the supply tray 22. In one example, the tray detection unit 33 is located at a position opposite to the pickup roller 24. The tray detection unit 33 is constituted by an optical sensor, for example.

[0053] The image reading device 13 has an operation unit. Specifically, the image reading device 13 has a reading operation unit 34. The reading operation unit 34 is operated by the user. The user operates the image reading device 13 through the reading operation unit 34. The reading operation unit 34 is a touch panel, for example. The reading operation unit 34 is not limited to a touch panel and may also be a button, a lever, or the like.

[0054] The image reading device 13 has a display unit. Specifically, the image reading device 13 has a reading display unit 35. The reading display unit 35 displays a screen. Specifically, the reading display unit 35 displays a screen for operating the image reading device 13. The user gives an instruction to the image reading device 13 through the screen displayed on the reading display unit 35.

[0055] The image reading device 13 has a control unit. Specifically, the image reading device 13 has a reading control unit 36. The reading control unit 36 controls the reading display unit 35. The reading control unit 36 performs control so that the reading display unit 35 displays a screen. The reading control unit 36 executes the instruction input through the screen displayed on the reading display unit 35. The reading control unit 36 may also control the image reading device 13 based on an instruction sent from the control device 12.

[0056] Similar to the terminal control unit 16, the reading control unit 36 may be constituted by one or more processors, may be constituted by one or more dedicated hardware circuits, or may also be constituted by a circuit including a combination of them.

[0057] A user generally places a stack of originals MA formed by stacking originals M1 to be read on an image reading device 13. However, sometimes an original M1 other than the one to be read is mixed into the stack of originals MA. For example, it is possible that an A5-sized original M1 or an original M1 made of recycled paper is mixed into a stack of originals MA formed by stacking A4-sized plain papers. In this case, if the image reading device 13 directly reads the original M1, the user may not obtain the desired reading result. Therefore, the image reading device 13 is configured to be able to confirm whether an original M1 that the user does not want is mixed into the stack of originals MA.

[0058] When the detection unit 27 detects an original M1 other than the one to be read, the reading control unit 36 causes the display unit to display that an original M1 other than the one to be read has been detected. The reading control unit 36 can cause the reading display unit 35 to display that an original M1 other than the one to be read has been detected, or can cause the terminal display unit 15 to display that an original M1 other than the one to be read has been detected through the terminal control unit 16. Thus, the user can grasp that an original M1 other than the one to be read is mixed into the stack of originals MA. By removing the original M1 other than the one to be read from the stack of originals MA, the user can obtain a stack of originals MA that only includes the originals M1 to be read. By placing this stack of originals MA on the image reading device 13, the user can obtain the desired reading result.

[0059] The reading control unit 36 is configured to be able to set object conditions for the original M1 to be read. The object conditions include at least one of the size of the original M1 and the category of the original M1. The object conditions can include only the size of the original M1, can include only the category of the original M1, or can include both. The object conditions are set through a screen displayed on the display unit. That is, the user sets the object conditions through a screen displayed on the reading display unit 35 or the terminal display unit 15. The screen will be described later. When the detection unit 27 detects an original M1 that does not meet the object conditions set through the display unit, the reading control unit 36 causes the display unit to display this situation.

[0060] The reading control unit 36 is configured to be able to execute a counting mode. The counting mode is a mode of counting the originals M1 that meet the object conditions. In the counting mode, the reading control unit 36 can also count the originals M1 that do not meet the object conditions in addition to counting the originals M1 that meet the object conditions.

[0061] The counting mode is executed by the user operating the operation unit. The counting mode can be executed by the user operating the reading operation unit 34, or can be executed by operating the terminal operation unit 14. In one example, the counting mode is a mode that does not accompany the reading by the reading unit 26. The counting mode can also accompany the reading by the reading unit 26.

[0062] In the counting mode, the reading control unit 36 notifies the user of the number of sheets of the original document M1 that meet the target conditions. For example, the reading control unit 36 causes the reading display unit 35 or the terminal display unit 15 to display the number of sheets of the original document M1 that meet the target conditions. Through the counting mode, the user can grasp the number of sheets of the original document M1 that meet the target conditions. The user can grasp that the original document stack MA includes original documents M1 that do not meet the target conditions based on the difference between the number of sheets of the original document M1 that meet the target conditions and the number of sheets of the original document M1 placed on the supply tray 22. In this regard, causing the display unit to display the number of sheets of the original document M1 that meet the target conditions has the same meaning as causing the display unit to display the detected original documents M1 that do not meet the target conditions. In the counting mode, the reading control unit 36 may also cause the display unit to display the number of sheets of the original document M1 that do not meet the target conditions. In this case, the user can intuitively grasp the detected original documents M1 that do not meet the target conditions.

[0063] The reading control unit 36 is configured to be able to execute the confirmation mode. The confirmation mode is a mode for confirming whether there are original documents M1 that do not meet the target conditions. That is, the confirmation mode is a mode for confirming whether the original document stack MA placed on the supply tray 22 includes original documents M1 that are not to be read.

[0064] The confirmation mode is executed by the user operating the operation unit. The confirmation mode can be executed by the user operating the reading operation unit 34, or can also be executed by operating the terminal operation unit 14. In one example, the confirmation mode is a mode that does not accompany the reading by the reading unit 26. The confirmation mode may also accompany the reading by the reading unit 26.

[0065] In the confirmation mode, when an original document M1 that does not meet the target conditions is detected, the reading control unit 36 notifies the user of this situation. For example, the reading control unit 36 causes the reading display unit 35 or the terminal display unit 15 to display a message notifying that an original document M1 that does not meet the target conditions has been detected. Through the confirmation mode, the user can grasp that the original document stack MA includes original documents M1 that do not meet the target conditions.

[0066] The reading control unit 36 may also be configured to be able to execute the total counting mode. The total counting mode is a mode for counting the original documents M1 without referring to the target conditions. That is, the total counting mode is a mode for counting all the original documents M1.

[0067] The total counting mode is executed by the user operating the operation unit. The total counting mode can be executed by the user operating the reading operation unit 34, or can also be executed by operating the terminal operation unit 14. In one example, the total counting mode is a mode that does not accompany the reading by the reading unit 26. The total counting mode may also accompany the reading by the reading unit 26.

[0068] In the total count mode, the reading control unit 36 notifies the user of the counted number of sheets of the original document M1. For example, the reading control unit 36 causes the reading display unit 35 or the terminal display unit 15 to display the counted number of sheets of the original document M1. Through the total count mode, the user can grasp the number of sheets of the original document M1 that makes up the original document stack MA.

[0069] The reading control unit 36 may also be configured to be able to execute a comparison mode. The comparison mode is a mode in which, after counting the original document M1 without referring to the target conditions, the total number of the original document M1 counted this time is compared with the total number of the original document M1 counted in the total count mode. The comparison mode is a mode for confirming whether other original documents M1 are mixed in the original document stack MA of the original document M1 counted in the total count mode or whether the original document M1 is missing.

[0070] The comparison mode is executed by the user operating the operation unit. The comparison mode can be executed by the user operating the reading operation unit 34, or can be executed by operating the terminal operation unit 14. In one example, the comparison mode is a mode that does not involve reading by the reading unit 26. The comparison mode may also involve reading by the reading unit 26.

[0071] The comparison mode can be executed after the total count mode has been executed. In the comparison mode, the reading control unit 36 counts the original document M1 without referring to the target conditions. In the comparison mode, the reading control unit 36 confirms whether the total number of the original document M1 counted this time is the same as the total number of the original document M1 counted in the total count mode. In the comparison mode, the reading control unit 36 notifies the user whether the total number of the original document M1 counted this time is the same as the total number of the original document M1 counted in the total count mode. For example, when the total number of the original document M1 counted this time is not the same as the total number of the original document M1 counted in the total count mode, the reading control unit 36 causes the reading display unit 35 or the terminal display unit 15 to display this situation. That is, the reading control unit 36 causes the reading display unit 35 or the terminal display unit 15 to display that the total number of the original document M1 counted this time is not the same as the total number of the original document M1 counted in the total count mode. Through the comparison mode, the user can grasp that an unwanted original document M1 is mixed in the original document stack MA, that the original document M1 is missing in the original document stack MA, etc.

[0072] Screen

[0073] Next, the screen displayed on the display unit will be described. The screens described later can be displayed on the terminal display unit 15 by the terminal control unit 16, or can be displayed on the reading display unit 35 by the reading control unit 36.

[0074] As Figure 2As shown, a plurality of buttons are displayed on the main screen 40. In one example, a reading button 41, a counting button 42, a confirmation button 43, a comparison button 44, etc. are displayed on the main screen 40. The reading button 41 is a button to start reading of the original manuscript M1. The counting button 42 is a button to start the counting mode or the total counting mode. The confirmation button 43 is a button to start the confirmation mode. The comparison button 44 is a button to start the comparison mode. The user operates the buttons to cause the image reading device 13 to read the original manuscript M1 or to execute the counting mode.

[0075] As Figure 3 shown, when the counting button 42 is operated on the main screen 40, a selection screen 45 is displayed. The selection screen 45 is a screen for selecting the counting mode or the total counting mode.

[0076] A plurality of buttons are displayed on the selection screen 45. In one example, a specified button 46 and an unspecified button 47 are displayed on the selection screen 45. The specified button 46 is a button to specify the original manuscript M1 to be the counting object. The specified button 46 is operated when counting the specified original manuscript M1. The specified button 46 is operated when setting the object conditions. When the specified button 46 is operated, the counting mode is started. The unspecified button 47 is a button not to specify the original manuscript M1 to be the counting object. The unspecified button 47 is operated when counting all the original manuscripts M1. The unspecified button 47 is operated when not setting the object conditions. When the unspecified button 47 is operated, the total counting mode is started. A message prompting the operation of either the specified button 46 or the unspecified button 47 may also be displayed on the selection screen 45.

[0077] As Figure 4 shown, when the specified button 46 is operated on the selection screen 45, a setting screen is displayed. Specifically, a counting setting screen 48 is displayed. The setting screen is a screen for setting the object conditions. The counting setting screen 48 is a screen for setting the conditions of the original manuscript M1 to be the object in the counting mode.

[0078] One or more buttons are displayed on the counting setting screen 48. At least one of a size specification button 49 and a category specification button 50 is displayed on the counting setting screen 48. On the counting setting screen 48, only the size specification button 49 may be displayed, only the category specification button 50 may be displayed, or both of these buttons may be displayed. In one example, both the size specification button 49 and the category specification button 50 are displayed on the counting setting screen 48.

[0079] The size specification button 49 is a button for specifying the size of the original document M1. When the size specification button 49 is operated, A5, A4, A3, B5, B4, etc. are displayed in the drop-down menu. The category specification button 50 is a button for specifying the category of the original document M1. When the category specification button 50 is operated, plain paper, high-quality paper, recycled paper, thick paper, etc. are displayed in the drop-down menu.

[0080] The start button 51 is displayed on the counting setting screen 48. When the start button 51 is operated, the counting of the original document M1 starts. When the start button 51 is operated, the original document M1 is counted based on the object conditions set by the size specification button 49 and the category specification button 50.

[0081] The end button 52 is displayed on the counting setting screen 48. When the end button 52 is operated, the counting mode ends. When the end button 52 is operated, the main screen 40 is displayed.

[0082] On the counting setting screen 48, multiple object conditions can also be set. For example, an object condition where the size is A4 and the category is plain paper, and an object condition where the size is A5 and the category is recycled paper can be set. In this case, the reading control unit 36 counts the original documents M1 that meet each object condition separately.

[0083] As Figure 5 shown, the current situation screen 53 can also be displayed in the counting mode. The current situation screen 53 is a screen that displays the current number of original document sheets counted. The current number of original documents M1 that meet the object conditions is displayed on the current situation screen 53. For example, the current number of original documents M1 with a size of A4 and a category of plain paper, and the current number of original documents M1 with a size of A5 and a category of recycled paper are displayed on the current situation screen 53. In one example, the current number of original documents M1 that do not meet the object conditions is also displayed on the current situation screen 53. In addition, information indicating which sheet of the original documents M1 that do not meet the object conditions is read since the start of the counting of the original document M1 can also be displayed on the current situation screen 53.

[0084] The end button 52 can also be displayed on the current situation screen 53. When the end button 52 is operated, the counting mode ends. Thus, the user can immediately end the counting mode. When the end button 52 is operated, the main screen 40 is displayed. The counting mode can also be temporarily interrupted by operating the end button 52.

[0085] As Figure 6 shown, when misfeed is detected in the counting mode, a change screen is displayed. Specifically, when the misfeed detection unit 32 detects misfeed in the counting mode, the counting change screen 54 is displayed. The change screen is a screen for asking about parameter changes of the conveying unit 23. The counting change screen 54 is a screen for asking about parameter changes of the conveying unit 23 in the counting mode.

[0086] On the count change screen 54, a message is displayed asking the user whether to change the parameters of the conveying unit 23 to reduce the occurrence of double feeding. On the count change screen 54, a message can also be displayed to inform the user that the processing speed will become slower when changing the parameters of the conveying unit 23. On the count change screen 54, a "Yes" button 55 and a "No" button 56 are displayed. When the "Yes" button 55 is operated, the parameters of the conveying unit 23 are changed. Specifically, the reading control unit 36 reduces the initial speed of the pickup roller 24. For example, the reading control unit 36 reduces the rotational speed of the pickup roller 24 immediately after it starts rotating. When the "No" button 56 is operated, the parameters of the conveying unit 23 are not changed.

[0087] As Figure 7 shown, the initial speed of the pickup roller 24 can also be made smaller. For example, when the "Yes" button 55 is operated on the count change screen 54, the relay speed of the pickup roller 24 can also be made smaller. In this example, when feeding the original document M1, the rotational speed of the pickup roller 24 changes in such a way as to reach the target speed via the relay speed. The pickup roller 24 accelerates to reach the target speed after rotating at the relay speed for a prescribed time.

[0088] In Figure 7 , the solid line is the rotational speed of the pickup roller 24 in the counting mode. The dashed line is the rotational speed of the pickup roller 24 after the parameter change. When the "Yes" button 55 is operated on the count change screen 54, the relay speed becomes smaller. For example, when the "Yes" button 55 is operated on the count change screen 54, the relay speed changes from the speed shown by the solid line to the speed shown by the dashed line.

[0089] In Figure 7 , the double-dashed line is the rotational speed of the pickup roller 24 when reading the original document M1. The rotational speed of the pickup roller 24 in the counting mode is smaller than the rotational speed of the pickup roller 24 when reading the original document M1. Thereby, the counting accuracy is improved.

[0090] As Figure 8 shown, the initial speed of the pickup roller 24 can also be made smaller. For example, when the "Yes" button 55 is operated on the count change screen 54, the acceleration of the pickup roller 24 can also be made smaller. In this example, the pickup roller 24 accelerates toward the target speed at a prescribed acceleration.

[0091] In Figure 8In [the figure], the solid line is the rotational speed of the pickup roller 24 in the counting mode. The dashed line is the rotational speed of the pickup roller 24 after parameter change. The double-dashed line is the rotational speed of the pickup roller 24 when reading the original document M1. When the "Yes" button 55 is operated in the count change screen 54, the acceleration becomes smaller. For example, when the "Yes" button 55 is operated in the count change screen 54, the acceleration is changed in such a way that the speed changes from the speed shown by the solid line to the speed shown by the dashed line.

[0092] As Figure 9 shown, the initial speed of the pickup roller 24 can also become smaller. For example, when the "Yes" button 55 is operated in the count change screen 54, the acceleration curve can also change in such a way that the initial speed of the pickup roller 24 becomes smaller. In this example, the pickup roller 24 accelerates toward the target speed at a prescribed acceleration.

[0093] In Figure 9 [the figure], the solid line is the rotational speed of the pickup roller 24 in the counting mode. The dashed line is the rotational speed of the pickup roller 24 after parameter change. When the "Yes" button 55 is operated in the count change screen 54, the acceleration curve changes. For example, when the "Yes" button 55 is operated in the count change screen 54, the acceleration curve changes from the solid line to the dashed line. In one example, the pickup roller 24 accelerates in such a way that the acceleration curve bulges downward in the first half of the acceleration interval and accelerates in such a way that the acceleration curve bulges upward in the second half of the acceleration interval.

[0094] As Figure 10 shown, when the "Yes" button 55 or the "No" button 56 is operated in the count change screen 54, a continuation screen is displayed. Specifically, a count continuation screen 57 is displayed. That is, when the double-feed detection unit 32 detects double-feed in the counting mode, the count continuation screen 57 is displayed. The continuation screen is a screen that asks the user whether to continue the mode. The count continuation screen 57 is a screen that asks the user whether to continue the counting mode. When double-feed is detected, it may not be possible to accurately count the original document M1. Therefore, the continuation screen is displayed.

[0095] A message asking the user whether to continue counting is displayed in the count continuation screen 57. The "Yes" button 55 and the "No" button 56 are displayed in the count continuation screen 57. When the "Yes" button 55 is operated, the counting mode is continued. In one example, when the "Yes" button 55 is operated, the current status screen 53 is displayed. When the "No" button 56 is operated, the counting mode ends. In one example, when the "No" button 56 is operated, the main screen 40 is displayed.

[0096] As Figure 11As shown, when all the original manuscripts M1 have been conveyed, an end screen is displayed. Specifically, after the last original manuscript M1 has been conveyed in the counting mode, a counting end screen 58 is displayed. The end screen is the screen displayed when the mode ends. The counting end screen 58 is the screen that ends the counting mode.

[0097] The execution result of the mode is displayed on the end screen. The counted number of original manuscripts M1 is displayed on the counting end screen 58. That is, the number of original manuscripts M1 that meet the object conditions is displayed on the counting end screen 58. For example, the number of original manuscripts M1 with a size of A4 and a category of plain paper, and the number of original manuscripts M1 with a size of A5 and a category of recycled paper are displayed on the counting end screen 58. In one example, the number of original manuscripts M1 that do not meet the object conditions is also displayed on the counting end screen 58. The user visually confirms the counting end screen 58 to grasp that there are original manuscripts M1 other than the ones to be read in the original manuscript stack MA. In addition, information indicating which original manuscript M1 that does not meet the object conditions is read at the nth sheet since the counting of the original manuscript M1 started can also be displayed on the current status screen 53.

[0098] An end button 52 is displayed on the counting end screen 58. When the end button 52 is operated, the counting end screen 58 closes. After the user confirms the counting result, the end button 52 is operated.

[0099] As Figure 12 [[ID=ID=11]]shown, when the end button 52 is operated on the counting end screen 58, a maintenance screen can also be displayed. Specifically, a counting maintenance screen 59 can be displayed when the counting mode that allows parameter changes of the conveying unit 23 ends in the counting change screen 54. In one example, when parameter changes of the conveying unit 23 are allowed through the counting change screen 5 , after the last original manuscript M1 has been conveyed in the counting mode, a counting maintenance screen 59 is displayed. The maintenance screen is a screen that asks the user whether to also maintain the parameter changes of the conveying unit 23 in the next mode. The counting maintenance screen 59 is a screen that asks the user whether to also maintain the parameter changes of the conveying unit 23 in the next counting mode.

[0100] A message asking the user whether to maintain the parameter changes of the conveying unit 23 is displayed on the counting maintenance screen 59. A "Yes" button 55 and a "No" button 56 are displayed on the counting maintenance screen 59. When the "Yes" button 55 is operated, the parameter changes of the conveying unit 23 are maintained. That is, in the next counting mode, the pickup roller 24 rotates in a state where the initial speed is small. When double feeding is detected in the next counting mode, the parameters of the conveying unit 23 can also be changed so that the initial speed of the pickup roller 24 becomes even smaller. When the "No" button 56 is operated, the parameter changes of the conveying unit 23 are not maintained. In the next counting mode, the pickup roller 24 rotates at the normal initial speed.

[0101] AsFigure 13 As shown, when the confirmation button 43 is operated on the main screen 40, the setting screen is displayed. Specifically, the confirmation setting screen 60 is displayed. The confirmation setting screen 60 is a screen for setting the conditions of the original manuscript M1 to be the object in the confirmation mode.

[0102] The confirmation setting screen 60 is the same screen as the counting setting screen 48. One or more buttons are displayed on the confirmation setting screen 60. At least one of the size designation button 49 and the category designation button 50 is displayed on the confirmation setting screen 60. In one example, both the size designation button 49 and the category designation button 50 are displayed on the confirmation setting screen 60.

[0103] The start button 51 is displayed on the confirmation setting screen 60. When the start button 51 is operated, the confirmation of the original manuscript M1 starts. When the start button 51 is operated, the original manuscript M1 is confirmed based on the object conditions set by the size designation button 49 and the category designation button 50.

[0104] The end button 52 is displayed on the confirmation setting screen 60. When the end button 52 is operated, the confirmation mode ends. When the end button 52 is operated, the main screen 40 is displayed.

[0105] On the confirmation setting screen 60, multiple object conditions can also be set. For example, the object conditions of size A4 and category plain paper, and the object conditions of size A5 and category recycled paper can also be set.

[0106] As Figure 14 shown, when double feeding is detected in the confirmation mode, the change screen is displayed. Specifically, in the confirmation mode, when the double feed detection unit 32 detects double feeding, the confirmation change screen 61 is displayed. The confirmation change screen 61 is a screen for asking about the parameter change of the conveying unit 23 in the confirmation mode.

[0107] The confirmation change screen 61 is the same screen as the counting change screen 54. A message asking the user whether to change the parameters of the conveying unit 23 to reduce the occurrence of double feeding is displayed on the confirmation change screen 61. A message informing the user that the processing speed will become slower when the parameters of the conveying unit 23 are changed can also be displayed on the confirmation change screen 61. The "Yes" button 55 and the "No" button 56 are displayed on the confirmation change screen 61. When the "Yes" button 55 is operated, the parameters of the conveying unit 23 are changed. Specifically, the reading control unit 36 reduces the initial speed of the pickup roller 24. For example, as Figure 7 , Figure 8 and Figure 9 as shown in the curve graphs such as etc., the reading control unit 36 reduces the rotational speed of the pickup roller 24. When the "No" button 56 is operated, the parameters of the conveying unit 23 are not changed.

[0108] AsFigure 15 As shown, when the "Yes" button 55 or the "No" button 56 is operated on the confirmation change screen 61, the continuation screen is displayed. Specifically, the confirmation continuation screen 62 is displayed. That is, when the double-feed detection unit 32 detects a double-feed in the confirmation mode, the confirmation continuation screen 62 is displayed. The confirmation continuation screen 62 is a screen that asks the user whether to continue the confirmation mode.

[0109] The confirmation continuation screen 62 is the same screen as the counting continuation screen 57. A message asking the user whether to continue counting is displayed on the confirmation continuation screen 62. The "Yes" button 55 and the "No" button 56 are displayed on the confirmation continuation screen 62. When the "Yes" button 55 is operated, the confirmation mode continues. When the "No" button 56 is operated, the confirmation mode ends. In one example, when the "No" button 56 is operated, the main screen 40 is displayed.

[0110] As Figure 16 shown, when an original M1 that does not meet the object conditions is detected in the confirmation mode, the notification screen 63 is displayed. Specifically, when the detection unit 27 detects an original M1 that does not meet the object conditions in the confirmation mode, the notification screen 63 is displayed. The notification screen 63 is a screen that notifies that an original M1 that does not meet the object conditions has been detected. A message notifying that an original M1 that does not meet the object conditions has been detected is displayed on the notification screen 63.

[0111] When the detection unit 27 detects an original M1 that does not meet the object conditions, the notification screen 63 is displayed after the conveying unit 23 is stopped. Thereby, the possibility of unnecessarily conveying the original M1 is reduced.

[0112] The notification screen 63 is also a screen that asks the user whether to continue the confirmation mode. A message asking the user whether to continue the confirmation mode is displayed on the notification screen 63. The "Yes" button 55 and the "No" button 56 are displayed on the notification screen 63. When the "Yes" button 55 is operated, the confirmation mode continues. When the "No" button 56 is operated, the confirmation mode ends. In one example, when the "No" button 56 is operated, the main screen 40 is displayed.

[0113] As Figure 17 shown, when all the originals M1 have been conveyed, the end screen is displayed. Specifically, when the last original M1 has been conveyed in the confirmation mode, the confirmation end screen 64 is displayed. The confirmation end screen 64 is a screen that ends the confirmation mode. The end button 52 is displayed on the confirmation end screen 64. When the end button 52 is operated, the confirmation end screen 64 closes.

[0114] As Figure 18As shown, when all the original manuscripts M1 have been conveyed, a maintenance screen can also be displayed. Specifically, a confirmation maintenance screen 65 can also be displayed when the confirmation mode that permits parameter changes of the conveying unit 23 ends in the confirmation change screen 61. In one example, when parameter changes of the conveying unit 23 are permitted through the confirmation change screen 61, after the last original manuscript M1 has been conveyed in the confirmation mode, the confirmation maintenance screen 65 is displayed. The confirmation maintenance screen 65 can be displayed instead of the confirmation end screen 64, or can be displayed after the confirmation end screen 64.

[0115] The confirmation maintenance screen 65 is the same screen as the counting maintenance screen 59. A message asking the user whether to maintain the parameter changes of the conveying unit 23 is displayed on the confirmation maintenance screen 65. An "OK" button 55 and a "Cancel" button 56 are displayed on the confirmation maintenance screen 65. When the "OK" button 55 is operated, the parameter changes of the conveying unit 23 are maintained. That is, in the next confirmation mode, the pickup roller 24 rotates in a state where the initial speed is low. When double feeding is detected in the next confirmation mode, the parameters of the conveying unit 23 can also be changed so that the initial speed of the pickup roller 24 becomes even lower. When the "Cancel" button 56 is operated, the parameter changes of the conveying unit 23 are not maintained. In the next confirmation mode, the pickup roller 24 rotates at the normal initial speed.

[0116] Flowchart

[0117] Next, the operation of the image reading system 11 will be described. Specifically, the operation in the counting mode and the operation in the confirmation mode will be described. The counting mode and the confirmation mode can be executed only by the reading control unit 36, or can be executed by the reading control unit 36 and the terminal control unit 16. Here, without distinguishing between the reading control unit 36 and the terminal control unit 16, it is only expressed as the control unit.

[0118] First, based on Figure 19 , the operation in the counting mode will be described. It should be noted that the same operation can be performed for the total counting mode. Figure 19 The flowchart shown starts by operating the counting button 42 on the main screen 40.

[0119] As Figure 19 shown, in step S11, the control unit displays the selection screen 45. The user selects the counting mode or the total counting mode on the selection screen 45.

[0120] In step S12, the control unit displays the counting setting screen 48. The user sets the target conditions on the counting setting screen 48.

[0121] In step S13, the control unit feeds the original document M1. Specifically, when the start button 51 is operated on the counting setting screen 48, the control unit feeds the original document M1. At this time, the control unit activates the pickup roller 24. It should be noted that in the total counting mode, step S12 is skipped. In the total counting mode, the process can also be transferred to step S13 after the unspecified button 47 is operated on the selection screen 45.

[0122] In step S14, the control unit detects the original document M1. Specifically, the control unit detects the original document M1 through the detection unit 27 and the stack feed detection unit 32.

[0123] In step S15, the control unit determines whether a stack feed has occurred. At this time, the control unit determines whether the stack feed detection unit 32 has detected a stack feed. If the stack feed detection unit 32 has not detected a stack feed, the control unit transfers the process to step S20. If the stack feed detection unit 32 has detected a stack feed, the control unit transfers the process to step S16.

[0124] In step S16, the control unit stops the conveyance of the original document M1. At this time, the control unit stops the conveyance unit 23.

[0125] In step S17, the control unit displays the count change screen 54. The user selects whether to allow parameter changes for the conveyance unit 23. If the user allows parameter changes, the control unit changes the parameters of the conveyance unit 23. If the user does not allow parameter changes, the parameters of the conveyance unit 23 are not changed.

[0126] In step S18, the control unit displays the count continuation screen 57. The user selects whether to continue the counting mode.

[0127] In step S19, the control unit determines whether to continue the counting mode. Specifically, the control unit determines whether the "Yes" button 55 or the "No" button 56 has been operated on the count continuation screen 57. If the "Yes" button 55 has been operated, the control unit returns the process to step S13. If the "No" button 56 has been operated, the control unit transfers the process to step S22.

[0128] In step S20, the control unit performs an incremental count on the original document M1. Specifically, the control unit performs an incremental count on the original document M1 based on a determination of whether the detected original document M1 meets the object conditions. In the counting mode, the control unit performs an incremental count based on the object conditions. In one example, the control unit performs an incremental count separately on the original document M1 that meets the object conditions and the original document M1 that does not meet the object conditions. In the total counting mode, the control unit performs an incremental count on the original document M1 without referring to the object conditions.

[0129] In step S21, the control unit determines whether there is a next original document M1. At this time, the control unit determines the presence or absence of the original document M1 based on whether the tray detection unit 33 detects the original document M1. If there is an original document M1 on the supply tray 22, the control unit returns the process to step S13. If there is no original document M1 on the supply tray 22, the control unit transfers the process to step S22.

[0130] In step S22, the control unit causes the count end screen 58 to be displayed.

[0131] In step S23, the control unit determines whether the parameters of the conveying unit 23 have been changed. Specifically, the control unit determines whether the change of the parameters of the conveying unit 23 is permitted in step S17. If the change of the parameters of the conveying unit 23 is permitted, the control unit transfers the process to step S24. If the change of the parameters of the conveying unit 23 is not permitted, the control unit ends the counting mode.

[0132] In step S24, the control unit causes the count maintenance screen 59 to be displayed. When the "Yes" button 55 or the "No" button 56 is operated on the count maintenance screen 59, the control unit ends the counting mode. If the "Yes" button 55 is operated in the total counting mode, the parameter change can also be reflected in the next total counting mode.

[0133] The control unit may also cause the current status screen 53 to be displayed when the selection screen 45, the count setting screen 48, the count change screen 54, the count continuation screen 57, the count end screen 58, the count maintenance screen 59, etc. are not displayed in the counting mode.

[0134] Next, based on Figure 20 The operations in the confirmation mode will be described. Figure 20 The flowchart shown starts by operating the confirmation button 43 on the main screen 40.

[0135] As Figure 20 shown, in step S31, the control unit causes the confirmation setting screen 60 to be displayed. The user sets the target conditions on the confirmation setting screen 60.

[0136] In step S32, the control unit feeds the original document M1. Specifically, when the start button 51 is operated on the confirmation setting screen 60, the control unit feeds the original document M1. At this time, the control unit activates the pickup roller 24.

[0137] In step S33, the control unit detects the original document M1. Specifically, the control unit detects the original document M1 through the detection unit 27 and the stacking detection unit 32.

[0138] In step S34, the control unit determines whether double feeding has occurred. At this time, the control unit determines whether the double feed detection unit 32 has detected double feeding. If the double feed detection unit 32 has not detected double feeding, the control unit transfers the process to step S39. If the double feed detection unit 32 has detected double feeding, the control unit transfers the process to step S35.

[0139] In step S35, the control unit stops the conveyance of the original document M1. At this time, the control unit stops the conveyance unit 23.

[0140] In step S36, the control unit causes the confirmation change screen 61 to be displayed. The user selects whether to permit parameter change of the conveyance unit 23. If the user permits parameter change, the control unit changes the parameters of the conveyance unit 23. If the user does not permit parameter change, the parameters of the conveyance unit 23 are not changed.

[0141] In step S37, the control unit causes the confirmation continue screen 62 to be displayed. The user selects whether to continue the confirmation mode.

[0142] In step S38, the control unit determines whether to continue the confirmation mode. For example, the control unit determines whether the "Yes" button 55 or the "No" button 56 has been operated on the confirmation continue screen 62. If the "Yes" button 55 has been operated, the control unit returns the process to step S32. If the "No" button 56 has been operated, the control unit transfers the process to step S43.

[0143] In step S39, the control unit determines whether the detected original document M1 meets the target conditions. If it meets the target conditions, the control unit transfers the process to step S42. If it does not meet the target conditions, the control unit transfers the process to step S40.

[0144] In step S40, the control unit ejects the original document M1. After the original document M1 is ejected, the control unit stops the conveyance unit 23.

[0145] In step S41, the control unit causes the notification screen 63 to be displayed. After causing the notification screen 63 to be displayed, the control unit transfers to step S38. In step S38, the control unit determines whether the "Yes" button 55 or the "No" button 56 has been operated on the notification screen 63.

[0146] In step S42, the control unit determines whether there is a next original document M1. At this time, the control unit determines the presence or absence of the original document M1 based on whether the tray detection unit 33 has detected the original document M1. If there is an original document M1 on the supply tray 22, the control unit returns the process to step S32. If there is no original document M1 on the supply tray 22, the control unit transfers the process to step S43.

[0147] In step S43, the control unit determines whether the parameters of the conveying unit 23 have been changed. Specifically, the control unit determines whether the parameter change of the conveying unit 23 has been permitted in step S36. When the parameter change of the conveying unit 23 is permitted, the control unit transfers the process to step S45. When the parameter change of the conveying unit 23 is not permitted, the control unit transfers the process to step S44.

[0148] In step S44, the control unit causes the confirmation end screen 64 to be displayed. When the end button 52 is operated on the confirmation end screen 64, the control unit ends the confirmation mode.

[0149] In step S45, the control unit causes the confirmation maintenance screen 65 to be displayed. When the "Yes" button 55 or the "No" button 56 is operated on the confirmation maintenance screen 65, the control unit ends the confirmation mode.

[0150] As described above, the control method of the image reading system 11 includes: the detection unit 27 detecting the original document M1; and when the original document M1 that does not meet the object conditions is detected, the display unit displaying the original document M1 that does not meet the object conditions.

[0151] Functions and effects of the embodiment

[0152] Next, the functions and effects of the above embodiment will be described.

[0153] (1) When the detection unit 27 detects the original document M1 that does not meet the object conditions set through the setting screen, the control unit causes the display unit to display the original document M1 that does not meet the object conditions. According to the above configuration, by the display unit displaying the original document M1 that does not meet the object conditions, the user can grasp that an unwanted original document M1 has been mixed in the original document stack MA. By removing the original document M1, the user can obtain the original document stack MA formed by stacking the original documents M1 that meet the object conditions. By reading the original document stack MA, the user can obtain the desired reading result.

[0154] (2) In the counting mode, the control unit causes the display unit to display the number of original documents M1 that meet the object conditions. According to the above configuration, the user can grasp the number of original documents M1 that are the reading objects.

[0155] (3) At least one of the size designation button 49 and the category designation button 50 and the start button 51 are displayed on the counting setting screen 48. According to the above configuration, the user can operate the setting of the object conditions and the start of the counting mode on the counting setting screen 48. Therefore, the usability is improved.

[0156] (4) In the counting mode, when the double-feed detection unit 32 detects double feeding, the control unit causes the count change screen 54 to be displayed. With the above configuration, it is difficult to cause double feeding by changing the parameters of the conveying unit 23.

[0157] (5) In the counting mode, when the double-feed detection unit 32 detects double feeding, the control unit causes the count continuation screen 57 to be displayed. When double feeding occurs, it is impossible to accurately count the original document M1. With the above configuration, when double feeding occurs, the counting mode can be immediately aborted.

[0158] (6) In the counting mode, after the last original document M1 has been conveyed, the control unit causes the display unit to display the count end screen 58. The number of original documents M1 that meet the target conditions and the number of original documents M1 that do not meet the target conditions are displayed on the count end screen 58. With the above configuration, the user can grasp the number of original documents M1 to be read and the number of original documents M1 that are not to be read.

[0159] (7) When parameter changes of the conveying unit 23 are permitted through the count change screen 54, after the last original document M1 has been conveyed in the counting mode, the control unit causes the count maintenance screen 59 to be displayed. With the above configuration, the possibility of double feeding can be reduced in the next counting mode.

[0160] (8) In the counting mode, the control unit causes the current status screen 53 to be displayed. With the above configuration, the user can grasp the current number of original documents to be read.

[0161] (9) In the confirmation mode, when the detection unit 27 detects an original document M1 that does not meet the target conditions, the control unit causes the notification screen 63 to be displayed. With the above configuration, the user can grasp that the original document stack MA includes original documents M1 that are not the reading targets.

[0162] (10) In the confirmation mode, when the double-feed detection unit 32 detects double feeding, the control unit causes the confirmation change screen 61 to be displayed. With the above configuration, it is difficult to cause double feeding by changing the parameters of the conveying unit 23.

[0163] (11) In the confirmation mode, when the double-feed detection unit 32 detects double feeding, the control unit causes the confirmation continuation screen 62 to be displayed. When double feeding occurs, it is impossible to accurately confirm the original document M1. With the above configuration, when double feeding occurs, the confirmation mode can be immediately aborted.
