[0003] Patent Document 1: Japanese Patent Application Publication No. 2018-195022

[0004] In actual reading, reading may fail. Reasons for information reading failure include deformation or contamination of the target area, missing characters, unclear characters, or incorrect characters. Documents that failed to read properly require re-reading or manual correction of the information.

[0005] The reading results are displayed in a table format. The table records, by plane, whether the reading result was successful. Furthermore, the table separately displays information about successfully read planes and failed planes.

[0006] Therefore, even if one looks at the table, it is difficult to determine whether both sides of a particular document have been successfully read or whether any sides have failed to be read. Furthermore, if rereading is required, it is also difficult to find the document to be reread if the documents forming the document stack are not arranged in the order of the student ID numbers. Summary of the Invention

[0007] An object of the present invention is to make it easier to find a target document compared to a case where information indicating the order in which documents that failed to be read were read in a bundle is not included in a list of reading results.

DETAILED DESCRIPTION

[0048] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0049] <Implementation Method 1>

[0050] <Overall System Structure>

[0051] Figure 1 This figure illustrates the conceptual structure of information processing system 1 used in Embodiment 1. Information processing system 1 comprises an image processing device 10 equipped with a scanner for reading documents, client terminals 20 operated by students, teachers, assistants, and the like, a management server 30 that manages management data, and a teaching support device 40 that records document image data and the like in management server 30.

[0052] Here, the image processing device 10 , the client terminal 20 , the management server 30 , and the teaching support device 40 are connected via a network 50 .

[0053] Figure 1 In the case of , there is one client terminal 20, but there are multiple client terminals 20 in the information processing system 1. For example, there are client terminals 20 operated by students, client terminals 20 operated by teachers, and client terminals 20 operated by assistants.

[0054] The image processing device 10 is equipped with a scanner that optically reads information recorded in an original document. The scanner scans the surface of the original document with linear light and inputs the reflected light from the original document to the optical sensor. The scanning here is performed relatively. Therefore, transporting the original document relative to the reading position of the scanner is also considered scanning. The optical sensor converts the intensity of the reflected light into a grayscale value and outputs it. The set of grayscale values ​​of each pixel is the image of the original document. The optical sensor uses, for example, CCD (Charge Coupled Devices) and CIS (Contact Image Sensor). In the case of this embodiment, an automatic document feeder is installed in the image processing device 10.

[0055] An automatic document feeder (ADF) is a device that continuously removes documents one by one from a stack of documents (hereinafter referred to as a "document stack") and transports them to the scanner's reading position. The image processing device 10 in this embodiment is capable of reading not only one side of a document but also both sides.

[0056] In this embodiment, the manuscript is a paper document used in educational institutions, such as a test paper, report, or attendance sheet. Ruled lines, frame lines, a QR (Quick Response) code, test content, instructions, and item names are pre-printed on the manuscript.

[0057] Students who attend class submit a manuscript with their student ID number or name handwritten on it to the teacher. When grading, the teacher handwrites comments and scores on the manuscript. Of course, there are also cases where student ID numbers and names are printed on the manuscript.

[0058] The management server 30 in this embodiment is, for example, a server used in a learning management system (LMS), a teaching system, a library system, etc. When the management server 30 is an LMS, learning history, achievements, attendance / absence records, and project submission records are managed as management data.

[0059] When the management server 30 is a teaching system, elective records, grades, grades, colleges, departments, majors, etc. are managed as management data.

[0060] When the management server 30 is a library system, borrowing records, browsing records, etc. are managed as management data.

[0061] Of course, one management server 30 is not limited to the specific system described above. For example, one management server 30 may operate as a plurality of the above systems. Furthermore, the management server 30 may cooperate with a plurality of image processing apparatuses 10 .

[0062] Information recorded in the management server 30 can be browsed from the client terminal 20. Students can browse learning materials and their own grades managed in the management server 30 from the client terminal 20. Teachers can browse students' grades managed in the management server 30 or upload learning materials to the management server 30 from the client terminal 20. Assistants assisting the teacher can browse a list of document reading results from the client terminal 20.

[0063] The teaching support device 40 has the function of recognizing characters or symbols such as a student ID number, name, or score recorded in a document and converting them into a character code string. The program that recognizes characters is called a character recognition engine. The characters or symbols to be recognized can be handwritten or printed.

[0064] The teaching support device 40 in this embodiment generates a list of statistically analyzed recognition results and records the list in the management server 30 .

[0065] The teaching support device 40 also has a function for sorting the scoring results by student ID number. This sorted list is also stored in the management server 30. Furthermore, the teaching support device 40 has a function for generating a reading history of the document stack and presenting it to the user. The teaching support device 40 is an example of an information processing device.

[0066] The teaching support device 40 in this embodiment is connected to the image processing device 10 via the network 50 , but may be directly connected to the image processing device 10 via a USB (=Universal Serial Bus) cable or the like.

[0067] The network 50 is, for example, the Internet, a LAN (Local Area Network), or Ethernet (registered trademark). The network 50 may be wireless or wired.

[0068] <Structure of each device>

[0069] <Structure of Image Processing Device>

[0070] Figure 2 This is a diagram for explaining a configuration example of the image processing device 10 used in the first embodiment. Figure 2 The structure of the image processing apparatus 10 shown corresponds to a multifunctional image forming apparatus.

[0078] The operation receiving unit 107 is composed of a touch sensor arranged on the surface of the display unit 106 , and is also composed of switches, buttons, etc. arranged on an operation panel or a housing surface.

[0079] The control unit 104 and each unit are connected via a bus 109 or a signal line (not shown).

[0080] <Configuration of client terminals, management servers, and teaching support devices>

[0081] Figure 3 This figure explains an example of the configuration of the client terminal 20, the management server 30, and the teaching support device 40. The client terminal 20, the management server 30, and the teaching support device 40 are all based on computers. Figure 3 In the embodiment, the teaching support device 40 is described as a representative example.

[0082] The teaching support device 40 includes a control unit 401 for controlling the overall operation of the device, a storage unit 402 for storing image data and the like, and a communication interface (communication IF) 403 for enabling communication via a LAN cable or the like.

[0083] The control unit 401 includes a CPU 411, a ROM 412 storing firmware, BIOS, etc., and a RAM 413 used as a work area. The CPU 411 may be a multi-core CPU. The ROM 412 may be a rewritable nonvolatile semiconductor memory.

[0084] The storage unit 402 is a nonvolatile storage device, such as a hard disk drive (HDD) or a semiconductor memory. The storage unit 402 stores images of documents scanned by the image processing device 10, character recognition results, a statistical table recording the presence or absence of reading errors, and a list generated from the statistical table.

[0085] The control unit 401 and each unit are connected via a bus 404 or a signal line (not shown).

[0086] The management server 30 in this embodiment also has the same configuration as the teaching support device 40 .

[0087] Furthermore, the client terminal 20 in the present embodiment is provided with a display unit for displaying a work screen and the like and an operation receiving unit for receiving user operations as additional components.

[0088] The display unit used in the client terminal 20 is composed of, for example, a liquid crystal display, an organic EL display, etc. The display unit may be integrated with the main body of the client terminal 20 or connected to the main body of the client terminal 20 as an independent device.

[0089] The operation receiving unit used in the client terminal 20 includes a keyboard for inputting characters, a mouse for moving a pointer on an input screen, selecting a selection, and the like.

[0090] Figure 4 This is a diagram for explaining an example of the functional configuration of the control unit 401 constituting the teaching support device 40 used in the first embodiment. Figure 4 The functional modules shown are implemented by using CPU 411 (refer to Figure 3 ) to execute the program. In addition, Figure 4 The modules shown are part of a program executed by the control unit 401 .

[0091] The control unit 401 in this embodiment has the following module functions: Figure 1 ) in cooperation with each other to read in the image images of each original in sequence; a style determination module 422 that determines the style corresponding to the read image image; a character recognition module 423 that recognizes characters from a reading area specified by the style; a statistical table generation module 424 that generates a statistical table of the recognized information arranged in units of originals; a reading result addition module 425 that appends the contents of the reading result to the statistical table; a manuscript serial number addition module 426 that adds serial numbers indicating the order in which the originals were read; and a list generation module 427 that generates a list to be presented to the operator.

[0092] By comparing with the image processing device 10 (refer to Figure 1) cooperate with each other, the image reading module 421 in this embodiment reads the image image read from the original in the reading order. The image reading module 421 reads the image image in a manner that distinguishes the front and back sides of the original.

[0093] Figure 5 This is a diagram illustrating the relationship between the front and back sides of an original document when both sides of the original document are read. Figure 5 In the example shown in FIG, the front side of the document corresponds to the odd-numbered pages, and the back side corresponds to the even-numbered pages. Figure 5 The example is a case where two originals are processed as one set. Therefore, the front of the first sheet becomes page 1, the back of the first sheet becomes page 2, the front of the second sheet becomes page 3, and the back of the second sheet becomes page 4.

[0094] Alternatively, it is possible to process a document by taking the first side read as the front side and the next side read as the back side.

[0095] Figure 6 This is a diagram illustrating the relationship between the front and back sides of an original document when only one side of the original document is read. Figure 6 In the example, the page numbers are only marked on the surface. Figure 6 The example is a case where two originals are processed as one set. In this case, the first surface becomes page 1, and the second surface becomes page 2. Figure 6 In the example, the back page is not the object to be read, so it is not distinguished by page number.

[0096] Image reading module 421 (reference Figure 4 ) also from the image processing device 10 (reference Figure 1 ) obtains information indicating the order in which each document is read in a document stack.

[0097] Figure 7 This is a diagram illustrating the order of reading a document in this embodiment. Figure 7 In FIG, a plurality of original documents are stacked together to form a manuscript pile. Figure 7 In order to facilitate the description of the reading order, the first to sixth originals are intentionally described as separated. In an actual stack of originals, the originals are stacked without any gaps.

[0098] Figure 7 In the case of , the image images of the originals are read sequentially starting from the top of the original stack. Therefore, the original at the top position becomes the first original to be read, and the original at the second position becomes the second original to be read. The same applies to the rest.

[0099] Return to Figure 4 Description.

[0100] The pattern determination module 422 determines the pattern corresponding to the read image and sets the reading area used for character recognition. In addition, which items in the character recognition pattern are determined in advance.

[0101] Figure 8 This is a diagram for explaining an example of a manuscript that has not yet been entered. Figure 8 The document shown is an attendance sheet that also serves as an examination paper at a university.

[0102] This attendance sheet includes a column 61 for handwriting in the total number of pages and page numbers, a column 62 for handwriting in the grading results, a column 63 for handwriting in the student ID number, a column 64 for handwriting in the student's name, a column 65 for handwriting in the date of attendance, a column 66 for handwriting in the subjects taken, and a column 67 for handwriting in the answers, etc. Columns 61 to 66 are all surrounded by a frame.

[0103] The style determination module 422 in this embodiment (refer to Figure 4 ) The areas corresponding to columns 61 to 66 are set as reading areas.

[0104] Figure 9 This is a diagram illustrating an example of a graded manuscript. Figure 9 In this case, the total number of pages and the page number read are both 1. The score is 15, and the student ID number is "1234567." In this example, the student ID number is a 7-digit string. The student's name is "Fujitaro." The subject is "Mathematics," and the class date is "2017 / 3 / 13."

[0105] Figure 10 This is a diagram illustrating another example of a scored manuscript. Figure 10 The example corresponds to both sides of one original. Figure 10 In the case of , the front side is page 1 and the back side is page 2. Therefore, the total number of pages is 2. Therefore, "1 / 2" is written in column 61 of page 1, and "2 / 2" is written in column 61 of page 2.

[0106] in addition, Figure 10 In the example of , a score column 68 for each question is also provided on each page.

[0107] Figure 10 In the case of a PIN, the front and back sides have different styles. Therefore, the area to be read for character recognition is also set separately.

[0108] Return to Figure 4 Description.

[0109] The character recognition module 423 recognizes characters written in a specified area in the image corresponding to each page and outputs the characters as character codes. The recognized character strings are linked to the item names of the corresponding columns.

[0110] The statistical table generation module 424 generates a statistical table that lists information read from each document. In the present embodiment, the statistical table is a master table that collects all information related to document reading.

[0111] The read result appending module 425 appends the processing results, indicating the contents of the read results, to the list generated from the statistical table. For example, for a page that was successfully read, "Normal completion" is appended to the list. On the other hand, for a page where an error occurred during reading, the cause of the error is appended to the list. Examples of error causes include "Insufficient pages" and "Failed to determine the style." The error here indicates a read failure. The read result appending module 425 is an example of an extraction unit.

[0112] The document serial number adding module 426 adds a serial number indicating the order in which the document corresponding to the page to be read is read from the start of reading to the corresponding position in the statistical table. Figure 7 The numbers in the order in which they are read are the same as those described in .

[0113] Figure 11 This is a diagram for explaining an example of a statistical table to which reading results and serial numbers of original documents are added.

[0114] Figure 11 The statistical table shown is composed of, from the left end column to the right, a column 71 indicating the serial number of the read page, a column 72 indicating the order in which the original documents to be read are read, a column 73 indicating the distinction between the front and back sides, a column 74 indicating whether the style determination is successful, a column 75 indicating the student ID number that was successfully read, a column 76 indicating the page number within the total number of pages, and a column 77 indicating the total number of pages. Figure 11 In the example, due to paper limitations, information such as the names of the successfully read students or the scoring results are not included in the statistical table.

[0115] Figure 11 In this example, a student with ID number "1812001" submitted a time sheet after entering two originals for a total of four pages. However, the pattern could not be determined for the second document surface from the start of the scan. Therefore, the image shows "NG." Because the pattern could not be determined, the student ID number and page number fields on that page are blank.

[0116] The student with student ID number "1812010" submitted the attendance sheet after recording the original document as 1 sheet and the total number of pages as 2.

[0117] Figure 11 In the case of , the student's manuscript corresponds to the third manuscript read from the beginning of reading. Figure 11 As shown in FIG. 1 , the patterns of both the front and back sides of the third document read were successfully determined. Therefore, “OK” is indicated in the figure.

[0118] Of course, being able to determine the style and recognizing the characters recorded are not the same situation. For example, even if the style is determined, if the characters of the student ID number are not clear, then the student ID number cannot be recognized.

[0119] Figure 11 In the example, the student ID number was successfully recognized on both the front and back of the document. Furthermore, the front page of the document corresponding to the student with ID number "1812010" is page numbered "1," with a total of "2" pages. Meanwhile, the back page of the document is page numbered "2," with a total of "2" pages.

[0120] The student with student ID number "1812020" submitted the attendance sheet after recording the original document as 1 sheet and the total number of pages as 1.

[0121] Figure 11 In the example, the front side of the fourth document read from the start of scanning was successfully identified, but the back side was not. This is because the student ID number, etc., was not recorded on the back side. Since the style could not be determined, the student ID number and page number fields on that page were blank. However, since the document was recorded as one page in the total number of pages, even if the style on the back side could not be determined, the number of pages read was not insufficient. Therefore, the fourth document read was treated as a document that was processed normally.

[0122] Return to Figure 4 Description.

[0123] The list generation module 427 generates a list for operators to confirm the reading results based on the statistical table.

[0124] In this embodiment, in order to ensure the operator's work efficiency, the list is composed of an area where information of documents whose reading has been completed normally is arranged in a group and an area where information of documents in which errors occurred during reading is arranged in a group.

[0125] By distinguishing between the summary of information on documents where reading has completed normally and the summary of information on documents where reading errors occurred, documents where reading errors occurred can be more easily found than when the information on the two types of documents is displayed mixed in a disordered manner.

[0126] Here, a document whose reading has been completed normally refers to a document in which no error occurred when reading both the front and back surfaces.

[0127] On the other hand, a document with a reading error not only refers to a document with errors when reading both the front and back sides, but also includes a document with errors when reading either the front or back sides. For example, a document with an error when reading the back side is classified as a document with a reading error even if the front side is successfully read.

[0128] Reading errors include failure to determine the pattern and insufficient pages. If the pattern cannot be determined, it's unclear which area within the image to character recognize. Furthermore, the project associated with the recognized character information is unclear. On the other hand, if the total number of pages is known, insufficient pages can be confirmed by identifying the page numbers that were not read.

[0129] Figure 12 The client terminal 20 (refer to Figure 1 ) is a diagram illustrating an example of a list.

[0130] The operator here includes, for example, a teacher and an assistant who assists the teacher in the work. The list here is an example of a list of statistical results.

[0131] Figure 12 The shown list consists of, from the left end column to the right, a column 81 indicating the title number, a column 82 indicating the order in which the original documents to be read are read, a column 83 indicating the distinction between the front and back sides, a column 84 indicating the content of the processing results, and a column 85 indicating the student ID number that was successfully read.

[0132] The list is composed of a row 86 in which information on documents in which reading has been completed normally is summarized, and a row 87 in which information on documents in which reading errors have occurred is summarized.

[0133] In this embodiment, a row 86 that summarizes information on documents in which reading has been completed normally is arranged at the top of the list, and a row 87 that summarizes information on documents in which reading errors have occurred is arranged at the bottom of the list.

[0134] As mentioned above, the fourth document read has a total of one page. Therefore, even though the back side, which does not exist, cannot be read, the document is considered to have completed reading normally. This is because all pages have been read. Therefore, the information related to the student with ID number "1812020" is placed on row 86.

[0135] and Figure 12 The characteristic of the display of row 87 in the shown list is that the processing results of the front surface and the processing results of the back surface constituting one original are displayed side by side in two upper and lower rows.

[0136] Figure 12In the example shown in FIG, the read information of the student with the student ID number "1812001" corresponding to the first and second documents read from the start of reading is arranged on the side of row 87. This is because the total number of pages for the student with the student ID number "1812001" is 4, but the third page is missing.

[0137] Furthermore, row 87 displays information for the front and back sides of the first and second documents read since the start of reading, both submitted by the same student. This is because, although the back side of the second document was read successfully, the front side could not be determined. Regarding the first document, both sides were read successfully, but not all pages for the same student were complete, so it was considered insufficient.

[0138] By using Figure 12 The list shown makes it easier for operators to confirm the occurrence of reading errors.

[0139] Furthermore, the information on the document in which the reading error occurred includes a number indicating the order in which the document was read in the document pile. Therefore, when searching for the document in which the reading error occurred in the document pile, it is easy for the operator to find the corresponding document.

[0140] The list generation module 427 is an example of a generation unit.

[0141] <Processing Action Example>

[0142] Hereinafter, the processing operation of the first embodiment will be described.

[0143] First, let's explain the preparation phase. As part of the preparation phase, the teacher grades the attendance sheets collected from students, which double as exam papers. Hereinafter, the attendance sheets will be referred to as the originals. The originals are not necessarily sorted in the order of student ID numbers or names.

[0144] After that, the worker places the scored document stack on the paper feed tray of the automatic document feeder.

[0145] At this stage, the operator instructs reading of the document bundle.

[0146] Figure 13 It is displayed on the image processing device 10 (refer to Figure 1 ) is a diagram of an example of a guidance screen 91 of the display unit 106.

[0147] Figure 13 In the case of , the guidance screen 91 displays “Please place the document stack on the paper feed tray and press the read button.” The operator clicks the read button 92 according to the instruction on the guidance screen 91 .

[0148] Thereafter, processing by the information processing system 1 starts.

[0149] Figure 14 This is a flowchart for explaining an example of processing operations executed in the information processing system 1. Reference numeral S in the figure represents a step.

[0150] When the operator clicks the read button 92, the image reading unit 101 (refer to Figure 2 ) begins reading the document. The automatic document feeder (not shown) takes the documents out of the document stack one by one and reads the image of each document in sequence (step 1). When reading the image, the front side and the back side are read separately.

[0151] The front image and the back image read from one original are sequentially sent to the teaching support device 40 (refer to Figure 1 ).

[0152] The teaching aid device 40 determines the pattern of the received image (step 2). This determination is performed by comparing it with images of pre-prepared patterns. If the pattern is identified, the reading area for character recognition is also determined.

[0153] Next, the teaching support device 40 determines whether the determination is successful (step 3).

[0154] If a negative result is obtained in step 3, the teaching support device 40 records NG in the statistical table (refer to Figure 11 ) (step 4) and go to step 7 described later.

[0155] The statistical table also records serial numbers that are associated with NGs and indicate the order in which the documents being processed were read from the start of reading.

[0156] In this embodiment, read error determination is performed on a page-by-page basis. In other words, read error determination is performed on a plane-by-plane basis. Therefore, the pattern determination in step 2, the determination in step 3, and the recording of NG in step 4 are all performed on a page-by-page basis.

[0157] When a positive result is obtained in step 3 , the teaching support device 40 reads the student ID number, page number, total number of pages, etc. from the reading area set for the determined form (step 5 ).

[0158] Next, the teaching support device 40 records the read information in the statistical table (step 6). The reading in step 5 and the recording in step 6 are both performed in units of pages. As described above, the record of each page also records the read number of the corresponding original document.

[0159] Thereafter, the teaching support device 40 determines whether there are any unprocessed pages (step 7 ).

[0160] If a negative result is obtained in step 7 , the teaching support device 40 returns to step 1 .

[0161] On the other hand, if a positive result is obtained in step 7, the teaching support device 40 generates a list using the statistical table (refer to Figure 12 ) (Step 8). The above statistical table and the summary table here are recorded in the management server 30 through the teaching auxiliary device 40 (refer to Figure 1 )middle.

[0162] After that, the teaching support device 40 reads the client terminal 20 (refer to Figure 1 )Notify the generation of the list (step 9).

[0163] Figure 15 (A) and Figure 15 (B) is a diagram showing an example of a screen displayed on the client terminal 20 operated by the operator who reads the document. Figure 15 (A) is a screen 93 for generating a notification list. Figure 15 (B) is a screen 95 for downloading the list.

[0164] Figure 15 (A) and Figure 15 In the case of (B), a message “A list of statistical results has been generated. Please access the management server via a Web browser to download it.” and an OK button 94 are displayed on the screen 93 .

[0165] When the OK button 94 is operated, a screen 95 is displayed. Figure 15 (A) and Figure 15 In the case of (B), the screen 95 displays the words "List of download statistics results", words explaining the operation to be performed when the download button 96 is pressed, and the downloaded file name.

[0166] In addition, if the downloaded file is opened, it will be displayed Figure 12 The list shown.

[0167] <Implementation Method 2>

[0168] Next, the second embodiment will be described. In this embodiment, Figure 1 That is, this embodiment also uses the information processing system 1 composed of the image processing device 10, the client terminal 20, the management server 30 and the teaching support device 40.

[0169] However, in this embodiment, a new function is added to the teaching support device 40 .

[0170] <Structure of teaching support equipment>

[0171] Figure 16 This is a diagram for explaining an example of the functional configuration of the control unit 401 constituting the teaching support device 40 used in the second embodiment. Figure 16 The Figure 4 The symbols corresponding to the corresponding parts of .

[0172] Figure 16 The functional modules shown are also realized by utilizing CPU 411 (refer to Figure 3 ) to execute the program. In addition, Figure 16 The modules shown are part of a program executed by the control unit 401 .

[0173] In the case of this embodiment, the function structure described in the first embodiment is different in that the function of the additional error file generation module 428 is added.

[0174] The error file generation module 428 generates an error file that describes error information in units of manuscripts. In the present embodiment, the error file is generated as a PDF (Portable Document Format) document.

[0175] Therefore, the error file contains information about both the front and back pages. Furthermore, the arrangement of the pages in the error file depends on the order in which the two sides of a single document are read. For example, if the back side is read first, the first page in the error file will be the back side, and the next page will be the front side.

[0176] The file name of the generated error file is displayed in association with the document corresponding to the list.

[0177] The error file generation module 428 in this embodiment adds a number indicating the order in which documents were read to a part of the file name of the error file according to a predetermined rule.

[0178] If the file name rule is known, the order in which the documents that have generated reading errors are read can be known simply by looking at the file names.

[0179] In the present embodiment, a number indicating the order in which the documents were read is appended to the beginning of the file name. If a number indicating the order in which the documents were read is recorded at the beginning of the file name, the error information can be sorted in the order in which the documents were read by sorting the file names in the order of their first characters.

[0180] <Processing Action Example>

[0181] The following describes the processing operations of the second embodiment.

[0182] Figure 17 This is a flowchart illustrating an example of processing operations executed in the information processing system 1 . Figure 17 The Figure 14 The symbols corresponding to the corresponding parts of .

[0183] Figure 17 The processing action shown is different from the one shown in that the processing for generating an error file (step 10) is provided immediately after step 7. Figure 14 .

[0184] As described above, when a positive result is obtained in step 7, a statistical table summarizing the reading results is generated for all the documents to be read.

[0185] In this embodiment, the teaching support device 40 generates an error file for documents including pages where reading errors occur (step 10). At this time, the teaching support device 40 adds a number indicating the reading order of the corresponding document to the beginning of the error file file name.

[0186] Furthermore, in the present embodiment, in step 8 executed immediately after step 10 , the teaching support device 40 generates a list including file names.

[0187] Figure 18 The client terminal 20 (refer to Figure 1 ) is a diagram illustrating another example of a list. Figure 18 The Figure 12 The symbols corresponding to the corresponding parts of .

[0188] Figure 18 The structure of the table shown is basically the same as Figure 12 The difference is that Figure 18 A column 88 indicating the file name of the error file is provided at the right end of the shown list.

[0189] Figure 18 In the example, the file name of the error file is displayed in row 87, which summarizes the information about documents that had errors during reading. For example, the document with student ID number "1812001" is the first and second document to be read from the start. Therefore, the file names "1-1812001.pdf" and "2-1812001.pdf" are displayed for the front and back sides of the same document, respectively.

[0190] In the case of the file name here, the first character "1" indicates the first document to be read, and the first character "2" indicates the second document to be read.

[0191] In this embodiment, the same file name is displayed in the row corresponding to the front and back sides. This is because read errors are managed on a page-by-page basis. Furthermore, if a file name is associated with each page, even if the read result information corresponding to the front and back sides of the same document is not displayed side by side due to sorting, it is easy to find the corresponding document.

[0192] Furthermore, in the case of this embodiment, link information to the error file is embedded in the file name.

[0193] <Other Implementation Methods>

Furthermore, the teaching assistance device 40 may be implemented as a cloud server or a local server.

[0197] In the above embodiment, an example of confirming the list generated by the teaching auxiliary device 40 by browsing from the client terminal 20 has been described. However, a function of automatically printing the generated list can be provided in the teaching auxiliary device 40. Specifically, a function can be provided so that, while the list of statistical results is generated, the teaching auxiliary device 40 automatically sends the print data corresponding to the list to the image processing device 10. Of course, the premise is that the image processing device 10 is provided with a function of printing images. Of course, even if the image processing device 10 used for reading the original is not provided with a function of printing images, the print data of the list can be sent to a printer provided near the image processing device 10 used for reading the original. If this function is provided, the reading result of the original can be confirmed at the reading position.
