[0021] Control device

[0022] 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 the 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.

[0023] 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.

[0026] <Image reading device>

[0027] The image reading device 13 is configured to read the original document M1. The image reading device 13 is, for example, a scanner that reads images such as characters and photos printed on an original document M1 such as paper or a film.

[0028] The image reading device 13 is provided with a housing 21.

[0029] The image reading device 13 is provided with a supply tray 22. A stack of original documents MA with multiple original documents M1 stacked thereon 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.

[0030] The image reading device 13 is provided with 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 inside the housing 21 to the outside of the housing 21.

[0031] 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 sandwiching the original document M1. The conveying unit 23 may have a deceleration roller for suppressing double feeding. Double feeding means that multiple original documents M1 are conveyed overlappingly. The deceleration roller rotates, for example, in a manner that causes the original document M1 to return from the housing 21 to the supply tray 22.

[0032] 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 generates image data of the original document M1 by reading the original document M1. The reading unit 26 can be configured to read one side of the original document M1 or can be configured to read both sides.

[0033] The image reading device 13 includes a tray detection unit 27. The tray detection unit 27 is configured to detect the original document M1. Specifically, the tray detection unit 27 detects the presence or absence of the original document M1 placed on the supply tray 22. In one example, the tray detection unit 27 is located at a position opposite to the pickup roller 24. The tray detection unit 27 is composed of an optical sensor, for example.

[0034] The image reading device 13 may also include a counting detection unit 28. The counting detection unit 28 is configured to detect the original document M1. Specifically, the counting detection unit 28 detects the original document M1 fed by the pickup roller 24. The image reading device 13 can count the original document M1 through the counting detection unit 28. In one example, the counting detection unit 28 is located between the reading unit 26 and the pickup roller 24. The counting detection unit 28 is composed of an optical sensor, for example.

[0035] The image reading device 13 may also include an operation unit. For example, the image reading device 13 may include a reading operation unit 31. The reading operation unit 31 is operated by the user. The user operates the image reading device 13 through the reading operation unit 31. The reading operation unit 31 is a touch panel, for example. The reading operation unit 31 is not limited to a touch panel and may also be a button, a lever, etc.

[0036] The image reading device 13 may also include a display unit. For example, the image reading device 13 may include a reading display unit 32. The reading display unit 32 displays a screen. Specifically, the reading display unit 32 displays a screen for operating the image reading device 13. The user provides an instruction to the image reading device 13 through the screen displayed on the reading display unit 32.

[0037] The image reading device 13 includes a control unit. Specifically, the image reading device 13 includes a reading control unit 33. The reading control unit 33 controls the reading display unit 32. The reading control unit 33 controls the reading display unit 32 in such a way as to display a screen. The reading control unit 33 executes the instruction input through the screen displayed on the reading display unit 32. The reading control unit 33 may also control the image reading device 13 based on an instruction sent from the control device 12.

[0038] The reading control unit 33, like the terminal control unit 16, can be constituted by one or more processors, can be constituted by one or more dedicated hardware circuits, or can be constituted by a circuit including a combination thereof.

[0039] The reading control unit 33 is configured to analyze the image data. The reading control unit 33 obtains information on the original document M1 by analyzing the image data. The reading control unit 33 obtains the RGB histogram or obtains the feature amount of the image by analyzing the image data. The reading control unit 33 can also identify the characters in the image by analyzing the image data.

[0040] The reading control unit 33 detects a specified original document M1 based on the analysis result of the image data. For example, the reading control unit 33 detects the original document M1 of white paper based on the image data. The reading control unit 33 detects the original document M1 with a background color based on the image data. The reading control unit 33 detects the monochromatic original document M1 based on the image data. The reading control unit 33 detects the color original document M1 based on the image data. The reading control unit 33 detects the original document M1 of a specified size based on the image data. The reading control unit 33 detects the original document M1 with page numbers attached based on the image data. In this way, the reading control unit 33 can determine the category of the original document M1 based on the image data. It is also possible that the terminal control unit 16 analyzes the image data instead of the reading control unit 33. In this case, the reading control unit 33 sends the image data to the terminal control unit 16.

[0041] The reading control unit 33 detects a specified original document M1 based on the number of pixels for each RGB. The reading control unit 33 detects a specified original document M1 based on the ratio of the luminance values in the RGB histogram. That is, the reading control unit 33 determines the category of the original document M1 based on the relative degree of the luminance values. For example, the reading control unit 33 detects the original document M1 of white paper based on the ratio of the luminance value indicating white. The reading control unit 33 detects the original document M1 with a background color based on the ratio of the luminance value that becomes the background color. The reading control unit 33 detects the monochromatic original document M1 based on the ratio of the luminance value indicating white and the ratio of the luminance value indicating black. The reading control unit 33 detects the color original document M1 based on the ratio of the luminance values of colors other than white and black.

[0042] The reading control unit 33 is not limited to the relative degree of the luminance values, and can also detect a specified original document M1 by other methods. For example, the reading control unit 33 can also detect the original document M1 of a specified size by edge extraction. The reading control unit 33 can also detect the original document M1 with page numbers attached by character recognition.

[0043] The reading control unit 33 is configured to be able to count the originals M1. Specifically, the reading control unit 33 counts the originals M1 by sequentially feeding the originals M1 one by one from the stack of originals MA placed on the supply tray 22. The reading control unit 33 can count the originals M1 either through the counting detection unit 28 or based on the image data. The reading control unit 33 causes the display unit to display the number of the counted originals M1. Thereby, the user can grasp the number of the originals M1 that make up the stack of originals MA. The reading control unit 33 can cause the reading display unit 32 to display the number of the counted originals M1, or can cause the terminal display unit 15 to display through the terminal control unit 16. It is also possible that the terminal control unit 16 counts the originals M1 instead of the reading control unit 33. The terminal control unit 16 can also cause the terminal display unit 15 to display the number of the counted originals M1.

[0044] When the user creates a stack of originals MA composed of a desired number of originals M1, the user sometimes causes the image reading device 13 to count the originals M1. At this time, the user places the stack of originals MA in which the originals M1 to be read are stacked on the image reading device 13. However, sometimes the originals M1 that are not the reading objects are mixed into the stack of originals MA. For example, sometimes the original M1 of white paper is mixed into the stack of originals MA. In the stack of originals MA in which the originals M1 of A4 size are stacked, sometimes the original M1 of A5 size is mixed. Sometimes the monochromatic original M1 is mixed into the stack of originals MA in which the colored originals M1 are stacked. In such a case, the user cannot accurately grasp the number of the originals M1 that are the reading objects. In contrast to this point, the image reading device 13 is configured to be able to count the originals M1 that are the reading objects.

[0045] The reading control unit 33 is configured to be able to set the object conditions for the originals M1 that are the reading objects. The object conditions include one or more conditions. In one example, the object conditions include the white paper condition, the background color condition, the color condition, the reference condition, the size condition, the page number condition, etc. The object conditions are set through the screen displayed on the display unit. That is, the user sets the object conditions through the screen displayed on the reading display unit 32 or the terminal display unit 15. The screen will be described later. The reading control unit 33 counts the originals M1 based on the object conditions.

[0046] The white paper condition is a condition for excluding the original M1 that is white paper. For example, the reading control unit 33 determines that the original M1 that is white paper is outside the reading objects based on the white paper condition. The reading control unit 33 can count the originals M1 from which the original M1 that is white paper has been excluded based on the white paper condition.

[0047] The background color condition is a condition for excluding the original document M1 that presents the background color. For example, the reading control unit 33 determines that the original document M1 presenting the background color is not an object to be read based on the background color condition. The reading control unit 33 can count the original document M1 from which the original document M1 presenting the background color has been excluded based on the background color condition. The background color condition can also be a condition for excluding the original document M1 that presents a specified background color. In one example, the reading control unit 33 detects the background color of the original document M1 based on the RGB histogram. For example, the reading control unit 33 sets the interval including the luminance value with the most frequent number of pixels in the histogram as the background interval. When the relative degree in the background interval is equal to or greater than a specified value, the reading control unit 33 determines that the background interval shows the luminance value of the background color. Thus, the reading control unit 33 can determine whether the original document M1 presents the specified background color. The reading control unit 33 can count the original document M1 from which the original document M1 presenting the specified background color has been excluded based on the background color condition.

[0048] The color condition is a condition for excluding the original document M1 as a color document or the original document M1 as a monochrome document. For example, the reading control unit 33 determines that the original document M1 as a color document or the original document M1 as a monochrome document is not an object to be read based on the color condition. The reading control unit 33 can count the original document M1 from which the original document M1 as a color document has been excluded, or the original document M1 from which the original document M1 as a monochrome document has been excluded based on the color condition. The color condition can also be a condition for excluding the original document M1 as a grayscale document. The reading control unit 33 can count the original document M1 from which the original document M1 as a grayscale document has been excluded based on the color condition.

[0049] The reference condition is a condition for excluding the original document M1 in which the number of pixels for each RGB of the image data is outside the specified range with respect to the reference data. For example, the reading control unit 33 determines that the original document M1 in which the number of pixels for each RGB is outside the specified range is not an object to be read based on the reference condition. The reading control unit 33 can count the original document M1 from which the original document M1 in which the number of pixels for each RGB is outside the specified range has been excluded. The reading control unit 33 determines whether the image data is data similar to the reference data based on the reference condition. The reading control unit 33 can count the original document M1 created in a common format based on the reference condition. For example, the reading control unit 33 can exclude the original document M1 other than the tag table, or exclude the original document M1 other than the resume based on the reference condition.

[0050] The reference conditions are set based on reference data. The reference data is data that serves as a reference for the number of pixels of each RGB. The reference data is the image data of a reference original. The reference data is obtained by previously causing the reading unit 26 to read the reference original. The reading control unit 33 determines whether the number of pixels of each RGB indicated by the image data is within a specified range with respect to the number of pixels of each RGB indicated by the reference data. When the number of pixels of each RGB indicated by the image data is within the specified range with respect to the number of pixels of each RGB indicated by the reference data, the reading control unit 33 determines that the original M1 is a reading target.

[0051] The reading control unit 33 may also determine the reference conditions based on the pixel number that is the most frequent in the histogram. For example, the reading control unit 33 may also determine whether the pixel number that is the most frequent in the image data is within a specified range with respect to the pixel number that is the most frequent in the reference data. The reading control unit 33 may also determine whether the difference between the pixel numbers is within a specified range.

[0052] The reading control unit 33 may also determine the reference conditions based on the distance between the centroid of the reference data and the centroid of the image data. In this example, the reference data and the image data are represented by point group data showing the number of pixels of each RGB. For example, the reading control unit 33 may also determine whether the distance between the centroid of the reference data and the centroid of the image data is within a specified range.

[0053] The size condition is a condition for excluding originals M1 of sizes other than a specified size. For example, the reading control unit 33 determines that an original M1 that is not of the specified size is not a reading target based on the size condition. The reading control unit 33 can count the originals M1 from which those that are not of the specified size have been excluded based on the size condition. That is, the reading control unit 33 can count only the originals M1 of the specified size.

[0054] The page number condition is a condition for excluding originals M1 that do not have page numbers attached. For example, the reading control unit 33 determines that an original M1 without a page number attached is not a reading target based on the page number condition. The reading control unit 33 can count the originals M1 from which those without page numbers attached have been excluded based on the page number condition. The page number condition may also be a condition for excluding originals M1 that do not have consecutive page numbers attached. For example, the reading control unit 33 determines that an original M1 with non-consecutive page numbers is not a reading target based on the page number condition. The reading control unit 33 can count the originals M1 from which those with non-consecutive page numbers have been excluded based on the page number condition.

[0055] The reading control unit 33 counts the originals M1 that meet the target conditions based on the image data. The reading control unit 33 causes the display unit to display the number of sheets of the originals M1 that meet the target conditions. Thereby, the user can accurately grasp the number of sheets of the originals M1 that are reading targets.

[0056] When the reading control unit 33 detects a document M1 that does not meet the object conditions based on the image data, the display unit is caused to display the detected document M1 that does not meet the object conditions. The reading control unit 33 can cause the reading display unit 32 to display the detected document M1 that does not meet the object conditions, or can cause the terminal display unit 15 to display through the terminal control unit 16. The terminal control unit 16 can also cause the terminal display unit 15 to display the detected document M1 that does not meet the object conditions when detecting a document M1 that does not meet the object conditions based on the image data. Thus, the user can grasp that a document M1 outside the reading object is mixed into the document stack MA, a document M1 with a specified page missing from the document stack MA, etc. By removing the document M1 outside the reading object from the document stack MA or supplementing the document M1 with the specified page to the document stack MA, the user can obtain a document stack MA that only contains the document M1 that is the reading object.

[0057] The reading control unit 33 is configured to be able to execute a counting mode. The counting mode is a mode for counting the documents M1 that meet the object conditions. The reading control unit 33 can also count the documents M1 that do not meet the object conditions in addition to counting the documents M1 that meet the object conditions in the counting mode. The reading control unit 33 can also count the documents M1 that meet the object conditions and the documents M1 that do not meet the object conditions separately.

[0058] The reading control unit 33 counts the documents M1 based on the image data in the counting mode. Therefore, the counting mode is accompanied by the reading by the reading unit 26. In the counting mode, the resolution of the reading unit 26 can also be smaller than when performing normal reading. In the counting mode, the reading unit 26 only needs to be able to read the document M1 at a resolution sufficient to determine whether it meets the object conditions.

[0059] The counting mode is executed by a user operating the operation unit. The counting mode can also be executed by a user operating the reading operation unit 31, and can also be executed by operating the terminal operation unit 14.

[0060] The reading control unit 33 notifies the user of the number of sheets of the documents M1 that meet the object conditions in the counting mode. For example, the reading control unit 33 causes the reading display unit 32 or the terminal display unit 15 to display the number of sheets of the documents M1 that meet the object conditions. Through the counting mode, the user can grasp the number of sheets of the documents M1 that meet the object conditions.

[0061] The reading control unit 33 can also notify the user of the number of sheets of the documents M1 that do not meet the object conditions in the counting mode. For example, the reading control unit 33 can also cause the reading display unit 32 or the terminal display unit 15 to display the number of sheets of the documents M1 that do not meet the object conditions.

[0062] The reading control unit 33 may also prompt the user with a recommended reading setting based on the analysis result of the image data in the counting mode. For example, when there is a large amount of monochromatic image data in the counted original document M1, the reading control unit 33 prompts the user with a reading setting that is easy to read characters. When there is a large amount of image data presenting a background color in the counted original document M1, the reading control unit 33 prompts the user with a reading setting for removing the background color. The reading control unit 33 may also cause the display unit to display the reading setting recommended from the image data obtained through the counting mode. Instead of the reading control unit 33, the reading setting recommended by the terminal control unit 16 may be prompted to the user.

[0063] The reading control unit 33 may also be configured to be able to execute the total counting mode. The total counting mode is a mode of counting the original document M1 without referring to the object conditions. That is, the total counting mode is a mode of counting all the original documents M1. The reading control unit 33 may count the original document M1 based on the image data in the total counting mode, or may count the original document M1 through the counting detection unit 28. That is, the total counting mode may not be accompanied by the reading by the reading unit 26, or may be accompanied by the reading by the reading unit 26.

[0064] The total counting mode is executed by a user operating the operation unit. The total counting mode may be executed by the user operating the reading operation unit 31, or may be executed by operating the terminal operation unit 14.

[0065] The reading control unit 33 notifies the user of the number of sheets of the counted original document M1 in the total counting mode. For example, the reading control unit 33 causes the reading display unit 32 or the terminal display unit 15 to display the number of sheets of the counted original document M1. Through the total counting mode, the user can grasp the number of sheets of the original document M1 that makes up the original document stack MA.

[0066] The reading control unit 33 may also be configured to be able to execute the comparison mode. The comparison mode is a mode of comparing the total number of the original documents M1 counted this time with the total number of the original documents M1 counted in the total counting mode after counting the original document M1 without referring to the object conditions. The comparison mode is a mode of confirming whether other original documents M1 are mixed in the original document stack MA formed by the original documents M1 counted in the total counting mode or whether the original document M1 is missing. The reading control unit 33 may count the original document M1 based on the image data in the comparison mode, or may count the original document M1 through the counting detection unit 28. That is, the comparison mode may not be accompanied by the reading by the reading unit 26, or may be accompanied by the reading by the reading unit 26.

[0067] The comparison mode is executed by a user operating the operation unit. The comparison mode may also be executed by the user operating the reading operation unit 31, or may also be executed by the user operating the terminal operation unit 14.

[0068] The comparison mode can be executed after the total counting mode. The reading control unit 33 counts the original document M1 without referring to the object conditions in the comparison mode. The reading control unit 33 confirms whether the total number of the original documents M1 counted this time is the same as the total number of the original documents M1 counted in the total counting mode in the comparison mode. The reading control unit 33 notifies the user in the comparison mode whether the total number of the original documents M1 counted this time is the same as the total number of the original documents M1 counted in the total counting mode. For example, when the total number of the original documents M1 counted this time is different from the total number of the original documents M1 counted in the total counting mode, the reading control unit 33 causes the reading display unit 32 or the terminal display unit 15 to display this meaning. That is, the reading control unit 33 causes the reading display unit 32 or the terminal display unit 15 to display that the total number of the original documents M1 counted this time is different from the total number of the original documents M1 counted in the total counting mode. Through the comparison mode, the user can grasp that an unexpected original document M1 is mixed in the original document stack MA, the original document M1 is missing from the original document stack MA, etc.

[0069] Screen

[0070] Next, the screen displayed on the display unit will be described. The screen described later can be displayed by the terminal control unit 16 on the terminal display unit 15, or can be displayed by the reading control unit 33 on the reading display unit 32.

[0071] As Figure 2 shown, a plurality of buttons are displayed on the home screen 40. In one example, a reading button 41, a counting button 42, a total counting button 43, a comparison button 44, etc. are displayed on the home screen 40. The reading button 41 is a button for starting the reading of the original document M1. The counting button 42 is a button for starting the counting mode. The total counting button 43 is a button for starting the total counting mode. The comparison button 44 is a button for starting the comparison mode. The user operates the button to cause the image reading device 13 to read the original document M1 or execute the counting mode.

[0072] A counting column 45 may also be displayed on the home screen 40. The counting column 45 is a column for displaying the cumulative number of sheets of the original document M1 counted by the counting mode. The user can grasp the number of sheets of the original document M1 counted through multiple counting modes by confirming the counting column 45. Usually, in the image reading device 13, there is an upper limit to the number of sheets of the original document M1 that can be placed on the supply tray 22. Therefore, when the user creates an original document stack MA with a number of sheets exceeding the upper limit that can be placed on the supply tray 22, the counting column 45 is useful. The display of the counting column 45 can be reset. For example, the display of the counting column 45 is reset by the user operating the operation unit.

[0073] As Figure 3As shown, when the count button 42 is operated on the home screen 40, the setting screen 46 is displayed. The setting screen 46 is a screen for setting object conditions. The setting screen 46 is a screen for setting the conditions of the original manuscript M1 to be read in the counting mode.

[0074] One or more condition buttons are displayed on the setting screen 46. In one example, a white paper condition button 47, a background color condition button 48, a color condition button 49, a reference condition button 50, a size condition button 51, and a page number condition button 52 are displayed on the setting screen 46. The condition button is a button for setting object conditions. For example, by operating the condition button, the condition screen is transferred to. It is also possible to perform a display showing whether the condition is valid or invalid on the condition button. In Figure 3 the example shown, the condition is shown to be valid by the condition button being displayed as on.

[0075] A start button 53 is displayed on the setting screen 46. When the start button 53 is operated, the counting of the original manuscript M1 based on the object conditions starts. When the start button 53 is operated, the original manuscript M1 is counted based on the object conditions set by the condition button.

[0076] It is also possible to display a return button 54 on the setting screen 46. When the return button 54 is operated, the home screen 40 is displayed. When the return button 54 is operated, the object conditions can be saved or reset. A count bar 45 can also be displayed on the setting screen 46.

[0077] As Figure 4 shown, when the white paper condition button 47 is operated on the setting screen 46, the white paper condition screen 55 is displayed. The white paper condition screen 55 is a screen for setting white paper conditions. The white paper condition screen 55 is a screen for switching the validity and invalidity of the white paper conditions.

[0078] An on button 56 and an off button 57 are displayed on the white paper condition screen 55. When the on button 56 is operated, the white paper condition becomes valid. When the off button 57 is operated, the white paper condition becomes invalid. A return button 54 is displayed on the white paper condition screen 55. When the return button 54 is operated, it returns to the setting screen 46.

[0079] When the background color condition button 48 is operated on the setting screen 46, the background color condition screen is displayed. The background color condition screen is a screen for setting background color conditions. In the background color condition screen, it is possible to specify the presence or absence of a background color, or to specify a prescribed background color.

[0080] When the color condition button 49 is operated on the setting screen 46, the color condition screen is displayed. The color condition screen is a screen for setting color conditions. In the color condition screen, it is possible to specify a color original or a monochrome original.

[0081] When the reference condition button 50 is operated on the setting screen 46, a reference condition screen is displayed. The reference condition screen is a screen for setting reference conditions. In the reference condition screen, for example, reference data can be specified or the threshold value can be changed.

[0082] When the size condition button 51 is operated on the setting screen 46, a size condition screen is displayed. The size condition screen is a screen for setting size conditions. In the size condition screen, the size of the original document M1 can be arbitrarily specified. In the size condition screen, the size of the original document M1 to be read can also be specified. In this case, the unspecified size is set as the size condition.

[0083] When the page number condition button 52 is operated on the setting screen 46, a page number condition screen is displayed. The page number condition screen is a screen for setting page number conditions. In the page number condition screen, the presence or absence of page numbers can be specified. In the page number condition screen, it can also be possible to specify that the page numbers are consecutive. In the page number condition screen, it can also be possible to specify the start number and the end number of the page numbers. In the page number condition screen, it can also be possible to specify the area with page numbers attached. When the page number condition becomes effective, since character recognition is required, the image analysis sometimes takes time. Therefore, when the page number condition becomes effective, a message indicating that the page number condition screen takes time to display can also be displayed.

[0084] As Figure 5 shown, when the start button 53 is operated on the setting screen 46, the current situation screen 58 is displayed. The current situation screen 58 is a screen for displaying the current number of original document sheets after counting. The current number of the original document M1 that meets the target conditions is displayed on the current situation screen 58. For example, the current number of the original document M1 that is not blank paper is displayed on the current situation screen 58.

[0085] A stop button 59 can also be displayed on the current situation screen 58. When the stop button 59 is operated, the counting mode ends. Thus, the user can immediately end the counting mode. When the stop button 59 is operated, the counting result is displayed. By operating the stop button 59, the counting mode can be temporarily interrupted.

[0086] As Figure 6 shown, when an original document M1 that does not meet the target conditions is detected during the counting mode, a notification screen 60 is displayed. The notification screen 60 is a screen for notifying that an original document M1 that does not meet the target conditions has been detected. A message notifying that an original document M1 that does not meet the target conditions has been detected is displayed on the notification screen 60.

[0087] When an original document M1 that does not meet the target conditions is detected, the notification screen 60 is displayed after stopping the conveying unit 23. Thereby, the possibility of unnecessarily conveying the original document M1 can be reduced.

[0088] The detection cause of the document M1 detected as not meeting the object conditions may also be displayed on the notification screen 60. That is, the condition content of the document M1 detected as not meeting the object conditions may also be displayed on the notification screen 60. For example, when the document M1 detected as a blank sheet of paper is detected, a message indicating the blank sheet condition may also be displayed on the notification screen 60. Thereby, the user can grasp the detection cause of the document M1 detected as not meeting the object conditions.

[0089] The notification screen 60 is a screen for asking the user whether to count the document M1 not meeting the object conditions as a document M1 meeting the object conditions. On the notification screen 60, a message asking the user whether to count the document M1 not meeting the object conditions as a document M1 meeting the object conditions is displayed.

[0090] A YES button 61 and a NO button 62 are displayed on the notification screen 60. When the YES button 61 is operated, the document M1 detected as not meeting the object conditions is counted as a document M1 meeting the object conditions. When the NO button 62 is operated, the document M1 detected as not meeting the object conditions is not counted as a document M1 meeting the object conditions. In one example, when the YES button 61 or the NO button 62 is operated on the notification screen 60, the driving of the conveying unit 23 restarts. When the YES button 61 or the NO button 62 is operated on the notification screen 60, the notification screen 60 closes.

[0091] In the image reading system 11, detection errors of the document M1 sometimes occur. For example, although the document M1 is not a blank sheet of paper, it is sometimes detected as a blank sheet of paper. In such a case, the user operates the YES button 61 on the notification screen 60. Thereby, even when a detection error of the document M1 occurs, the documents M1 to be read can be accurately counted. Thus, the user can grasp the number of documents M1 to be read.

[0092] As Figure 7 shown, when the counting of all the documents M1 is completed, a result screen 63 is displayed. When the stop button 59 is operated on the current situation screen 58, the result screen 63 may also be displayed. The result screen 63 is a screen for displaying the counting result. The number of the counted documents M1 is displayed on the result screen 63. That is, the number of the documents M1 meeting the object conditions is displayed on the result screen 63.

[0093] The number of the conveyed original manuscript M1 may also be displayed on the result screen 63. The number of the original manuscript M1 independent of the object conditions may also be displayed on the result screen 63. That is, the total number of the original manuscripts M1 placed on the supply tray 22 may also be displayed on the result screen 63. The total number of the original manuscripts M1 detected by the counting detection unit 28 may also be displayed on the result screen 63, and the total number of the original manuscripts M1 counted based on the image data may also be displayed. Thereby, the user can grasp the number of the original manuscripts M1 that are not the reading objects.

[0094] The number of the original manuscripts M1 that do not meet the object conditions may also be displayed on the result screen 63. Thereby, the user can intuitively grasp the number of the original manuscripts M1 that do not meet the object conditions. The detection cause of the original manuscript M1 that does not meet the object conditions may also be displayed on the result screen 63. In one example, the number of the original manuscripts M1 excluded by the white paper condition and the number of the original manuscripts M1 excluded by the color condition are displayed on the result screen 63. Thereby, the user can grasp the detection cause and the number of the original manuscripts M1 that do not meet the object conditions.

[0095] The OK button 64 is displayed on the result screen 63. When the OK button 64 is operated, the result screen 63 is closed. When the OK button 64 is operated, the counting mode ends. When the OK button 64 is operated, the home screen 40 is displayed.

[0096] <Flowchart>

[0097] Next, the operations during the counting mode will be described. The counting mode may be executed only by the reading control unit 33, or may be executed by the reading control unit 33 and the terminal control unit 16. Here, without distinguishing between the reading control unit 33 and the terminal control unit 16, they are only labeled as the control unit. Figure 8 The shown flowchart starts by operating the start button 53 on the setting screen 46. Regarding the total counting mode, it may also be operated according to Figure 8 the shown flowchart.

[0098] As Figure 8 shown, the control unit feeds the original manuscript M1 in step S11. At this time, the control unit activates the pickup roller 24.

[0099] The control unit reads the original manuscript M1 in step S12. Specifically, the control unit reads the original manuscript M1 through the reading unit 26. At this time, the image data is generated.

[0100] The control unit analyzes the image data in step S13. Specifically, the control unit analyzes the image data generated in step S12.

[0101] In step S14, the control unit determines whether the original document M1 meets the target conditions. Specifically, based on the image data parsed in step S13, the control unit determines whether the original document M1 meets the target conditions. That is, the control unit determines whether the original document M1 is the one to be read. If the original document M1 meets the target conditions, the control unit transfers the process to step S18. If the original document M1 does not meet the target conditions, the control unit transfers the process to step S15.

[0102] In step S15, the control unit stops the conveyance of the original document M1. At this time, the control unit stops the conveyance unit 23.

[0103] In step S16, the control unit displays the notification screen 60. At this time, the user is aware that the original document M1 that does not meet the target conditions has been detected. The user visually recognizes the notification screen 60 to understand the cause of the detection of the original document M1 that does not meet the target conditions.

[0104] In step S17, the control unit determines whether to count the original document M1 that does not meet the target conditions as an original document M1 that meets the target conditions. Specifically, the control unit determines whether the YES button 61 or the NO button 62 has been operated on the notification screen 60. If the YES button 61 has been operated on the notification screen 60, the control unit transfers the process to step S18. If the NO button 62 has been operated on the notification screen 60, the control unit transfers the process to step S19. If the NO button 62 has been operated on the notification screen 60, the control unit may also increment the count as the original document M1 that does not meet the target conditions.

[0105] In step S18, the control unit increments the count of the original document M1. Specifically, the control unit increments the count of the original document M1 that meets the target conditions.

[0106] In step S19, 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 27 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 S11. If there is no original document M1 on the supply tray 22, the control unit transfers the process to step S20.

[0107] In step S20, the control unit displays the result screen 63. The user is aware of the number of original documents M1 that meet the target conditions. The user is aware of the number of original documents M1 that do not meet the target conditions. The user is aware of the cause of the detection of the original document M1 that does not meet the target conditions. When the OK button 64 is operated on the result screen 63, the control unit ends the counting mode.

[0108] As described above, the control method of the image reading system 11 includes: counting the originals M1 that meet the object conditions based on the image data; and causing the display unit to display the number of the originals M1 that meet the object conditions.

[0109] <Functions and effects of the embodiment>

[0110] Next, the functions and effects of the above embodiment will be described.
