Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading means for reading an image of an original, such as a digital copying machine, and an image storing means for storing image information read by the means.
The present invention relates to an image processing apparatus provided with an image output means for forming an image on a sheet of image information stored in the image storage means and outputting the image information, and more particularly to an image processing apparatus having an automatic scoring function for answer sheets.

[0002]

[Prior Art] In various educational settings such as schools and cram schools, students can check the learning results of students and learners, judge the grades according to the learning results, give qualifications, or Frequent tests are conducted to make decisions. As for the question papers used for the various tests, a tester such as a teacher creates the questions and manuscripts himself and copies the required number of question papers with a copier or a simple printing machine, or a professional contractor. The ones that are printed by the company or the ones that are printed by the traders themselves also create the problems are used.

In addition, the grade of the answer sheet after the examination is usually done manually by a teacher who is an examiner at a school or the like, but an entrance examination, a qualification examination, or a large-scale mock examination is done. In this case, a large number of graders share the work, or automatic scoring is performed by an automatic scoring system using a computer. In addition, scoring results of answer sheets of a large number of examinees are totaled by using a computer, an average score and a deviation value are calculated, and a table and a graph are prepared.

[0004]

As described above, in the case of manually scoring the answer sheet, it takes a lot of time and labor, and not only the efficiency of scoring is poor, but also erroneous scoring may be performed. On the other hand, in the case of automatic scoring, many mark sheet methods are adopted in which the answer field of the answer sheet is answered in a predetermined method such as a filled mark, but the answer method is restricted to a very simple one. Not only that, its scoring device is also dedicated, and it is a high-speed processing device that reads a large number of answer sheets and scores in a short time.
It also requires a large amount of memory, which makes it very expensive. Furthermore, the device is large and its usage is special, so it could not be used in individual schools or learning classrooms.

Moreover, since it is only possible to read the mark sheet, it is necessary to purchase it as a dedicated machine, which is an obstacle to downsizing (dispersion). Also, since the answer sheet itself is not graded, it is not possible to return the graded answer sheet to the examinees and use it for learning.
There was also a problem that the examinees could not confirm the correctness of the answer to each question.

Therefore, an automatic scoring / totaling system has been developed in which the answer sheet is not limited to the mark sheet and can be directly scored on any answer sheet, and can be easily used personally by a teacher or the like. In this system, an answer sheet for scoring is set at a predetermined position on the scoring table, and the answer in the answer column is marked with a red pen or the like as in the conventional manual scoring method.
If you add a or ×, it will be automatically read and the total score will be calculated, and that data will be accumulated in the database to create a gradebook for each individual, and the correct answer rate and average score for each question will be displayed. It can also provide statistical information.

However, in such a system,
Grading (marking with ○ ×) itself must be done manually, and the total score on the graded answer sheet must also be filled in.
It takes time and labor for the grader to transcribe the score displayed on the display, which is hardly useful for labor saving.

The present invention has been made to solve the above-mentioned problems, and it is possible to obtain an image like a copying machine which is widely used in schools, especially a digital copying machine which has been rapidly spread in recent years. A reading unit (image scanner), an image storage unit (image memory) that stores the read image information, and an image output unit (printer unit) that forms and outputs the stored image information on a sheet of paper are provided. Using the image processing device, anyone can easily score any answer sheet, and the score result can be automatically output, and it is cheaper and more versatile than the conventional automatic scoring system. Therefore, the purpose is to be able to significantly reduce the scoring time.

Further, the present invention makes it possible to immediately know when a grading error or scoring error (error in scoring result) occurs on the answer sheet, and the scoring result of the answer sheet is displayed on the answer sheet. The objective is to always be able to form images in the correct orientation.

When the image processing apparatus of this embodiment is used in the normal copy mode, the ADF shown in FIG.
The original is set on the original table 107 of the document 102 with its face up, and
After the number of copies is designated by the numeric keypad 19 of the operation panel 10 shown in FIG. 1 (if the number of copies is one, it is not necessary to designate the number of copies), and if the start key 18 is pressed, the document on the document table 107 is fed by the ADF 102 to contact glass. The image plane is set downward at the exposure position on 101.

After that, the image of the original is read by the scanner section 100, and the image data is read by the image processing section 21.
The image processing as described above is performed by the image memory 41.
Then, a copy process is performed in which the printer unit 200 forms an image on a specified number of sheets of recording paper and discharges it as a copy.

Further, the document whose reading (exposure) has been completed is discharged by the ADF 102 as it is onto the discharge tray 114, or it is inverted and set again at the exposure position on the contact glass 101, and then the scanner unit 100 is used. A copy process similar to that described above is performed on the original, and the original that has been read is ADF1.
The sheet is discharged to the sheet discharge tray 114 by 02.

When the ADF 102 is used as a pressure plate, the user sets the original document at the exposure position on the contact glass 101 of the scanner section 100 with the document face down, and after designating the number of copies with the ten keys 19 of the operation panel 10, When the start key 18 is pressed, the image of the original is read by the scanner unit 100, the image data is subjected to the above-described image processing by the image processing unit 21 and stored in the image memory 41, and then the printer unit 200 stores it. Images are formed on the recording paper by the specified number. Further, the image processing apparatus of this embodiment can perform color copying of two colors, but since its operation is the same as that of a conventional two-color digital copying machine, detailed description thereof will be omitted.

The processing of the image processing apparatus 1 in the scoring mode, graph creating mode, question paper creating mode, etc., which are the modes relating to the present invention, will be described below with reference to FIG. Note that the processing corresponds to the case where the answer sheet and the question sheet are automatically fed by the ADF 102, but even when the answer sheet and the question sheet are manually set on the contact glass 101, the same processing is performed. Processing (a part of the processing including the processing of automatically feeding the original has been deleted) can be performed.

FIG. 15 is a diagram showing the processing flow of each of the above modes in association with the stored data. (A) is a scoring mode, (b) is a graph creating mode, and (c) is a problem paper creating mode routine. Is a processing flow of. The image data in the figure is stored in the image memory 41 shown in FIG. 12, and the recognition result data, the drawing data, and the graph creation data are stored in the RAM 2.
4, the font is stored in the ROM 23, the correct answer (and score) data, the explanation data, the scoring pattern (◯ ×, etc.), and the management data are stored in the data storage unit 39 in advance or after being recognized or created.

When the grading key 11 on the operation panel 10 shown in FIG. 12 is pressed, the grading mode is set, and the image plane is displayed on the document table 107 shown in FIG. 9 in the same manner as when copying an answer sheet to be scored as a document. Is set up and the start key 18 is pressed, the scoring mode routine shown in FIG.

In this routine, first, it is checked whether or not the answer sheet (original) is set on the original table 107 shown in FIG. 9 (using the output signal of the original detection sensor (not shown)), and it is set. For example, the ADF 102 automatically feeds a document on the document table 107, sets the document on the exposure position on the contact glass 101, and scans it with the scanner unit 1.
An image reading operation is performed in which the image of the original is read by 00, the image data is subjected to image processing by the image processing unit 21 as necessary, and the image data is stored in the image memory 41.

Next, the image data of the answer sheet that has just been read is read from the image memory 41, and the OCR unit 25 (and the barcode recognition unit 26) performs recognition processing on the image data. Here, the image area and the area of the read image data are identified, and the positions of the lines and the characters (including symbols and marks are simply referred to as “characters”) there are recognized.
Then, the respective characters (printed characters and handwriting) and ruled lines are recognized by the OCR processing.

If the answer sheet (question sheet) has ID information, it is recognized and the data storage section 39
The correct answer (and score) data for each question on the answer sheet to which this ID information is attached can be specified from the correct answer (and score) data for a large number of questions stored in advance and used in the scoring process. .

When ID information for identifying a question is printed by a barcode 71 as in the answer sheet 70 shown in FIG. 17, the barcode recognition unit 26 recognizes the barcode 71. It is possible to know the ID number by using the answer sheet, and the question column 72 of the answer sheet 70 as in the case described above.
The correct answer (and score) data for each question (question 1 to question 8) can be specified from the data stored in the data storage unit 39.

As shown in FIG. 18, the correct answer data includes a code of a character or symbol of correct answer information (or may be a pattern or a font) and position information indicating which position on the answer sheet the answer is.

In the OCR process, handwritten characters such as the examinee's number in the number field 73 and the answer character in the answer field 74 in the answer sheet 70 shown in FIG. 17 are also recognized. In the current handwritten character recognition technology, it is desirable to limit the characters that can be used to those that are easy to recognize, such as numbers, alphabets, katakana, symbols such as + and-, marks such as ○ and ×, but the recognition technology is improved. A wider variety of characters can be used.

After the recognition processing is completed, the recognition result data is stored in the RAM 24 in a predetermined format. Then, the scoring processing unit 42 uses the correct answer data stored in the data storage unit 39 to perform scoring processing on the answer of the recognition result. In the scoring process, as shown in the flowchart of FIG. 16, the answer data stored in the RAM 24 is answered one by one (for example, the answer sheet 70 shown in FIG. 17).
The answer data recognized from each of the columns 1 to 8 corresponding to each question in the answer column 74 are sequentially read), and the correct answer / score data for the question are read from the storage unit 39.

Then, the answer data and the correct answer data are matched, and it is judged whether or not the both data match (match). If they match, the correct answer is obtained, and therefore the score is calculated from the score data. For example, in the example of the answer sheet shown in FIG. 17, if each of the points of [Q1] to [Q4] is 10 points, if the answer to [Q1] is correct, the score is 10. The calculated score is added and stored in the RAM 24. At this time, it is preferable to store the judgment result of the correctness of the graded answer.

If the answer data and the correct answer data do not match, the score is not calculated and the addition is not stored because the answer is incorrect. If the points are the same for each question, the point data need only be read once, so there is no need to read it for each answer score. After that, it is judged whether or not there is the next answer data, and if there is, the process returns to the first step of reading the answer data, and the above processing is repeated until there is no answer data recognized from one answer sheet. If there is no answer data, it means that the scoring is completed, so the process exits this subroutine and returns to the routine shown in FIG.

Then, it is determined whether or not to print out, and normally the printout is performed. Therefore, the score data added and stored in the RAM 24 and the determination result of the correctness for each answer are also read if stored. An image drawing process for reading the scoring result by the scanner unit 100 and drawing an image on the image data of the answer sheet stored in the image memory 41 is performed.

When it is not necessary to print out, the scoring result data is transferred and stored as management data in the data storage unit 39, and the scoring result (score etc.) is displayed in a predetermined format on the LCD 34 shown in FIG. Thereafter, a document request process, that is, a message for requesting the user to set a document on the platen is displayed on the LCD 34. Then, it is determined whether the scoring mode is set, and if the setting is released, Ends this process, but otherwise returns to the first step and performs the same process as described above.

On the other hand, in the drawing process, the score of the scoring result is RO
Draw a number image using the font in M23,
If not only the score but also the mark indicating the correct answer or the incorrect answer is printed, the scoring pattern such as XX is also included in the data storage unit 39.
It is read from and is drawn corresponding to each answer position in the answer column. Further, with respect to an incorrect answer, a correct character or symbol, or further commentary data can be read from the data storage unit 39 and drawn. A cache memory may be used for these drawing.

The data of the marking result drawn in this way is sent to the selector 53 shown in FIG. 13 and is combined with the image data of the answer sheet read from the image memory 41, and the same recording sheet is printed by the printer section 200. At the same time, an image is formed and output as a scoring result output sheet 80 as shown in FIG. 19, then a document request process is performed, and thereafter the same process as described above is performed.

In this case, the scoring result output paper 80 is as shown in FIG.
The same image as the answer sheet 70 shown in is printed,
The score is printed in the score field 85 in a pattern like a handwritten character. With respect to the answer character in each field of the answer field 84, ○ is printed in the case of a correct answer, and × is printed in the case of a non-correct answer in a handwriting-like pattern. To be done. At that time, if the same image as the answer sheet is printed with black toner and the score and the pattern of ○ and × are printed with red toner, the scoring result is easier to understand and when the teacher gives a score on the answer sheet. It will be close. Furthermore, in the non-correct answer column, correct answer characters and the like and annotations can be printed with red toner.

The printing colors are not limited to black and red. If the developing units 204 and 207 shown in FIG. 9 are replaced with units using toners of other colors, it is possible to print with any two colors. In the case of printing in two colors, it is necessary to expand the drawing of the scoring result in another area of the memory without overwriting the image data on the answer sheet.

By the way, as shown in the answer sheet 70 'shown in FIG. 20, the bar code 7 in which the correct answer is encrypted is provided near the answer columns 1 to 8 of each question in the answer column 74'.
If 6 is printed, in the recognition processing of FIG. 15A, the barcode recognition unit 26 can sequentially recognize the position of the barcode and the code, and then decode the correct answer. By doing so, it is not necessary to recognize the question, and the answer data recognized for each question and the decoded correct answer data can be immediately compared (matched) to judge the correctness of the answer.

Next, when the graph key 12 on the operation panel 10 is selected, the graph creation mode is entered and the graph creation mode routine shown in FIG. 15B starts. In this routine, first the parameters for the desired data,
That is, the history of scoring results of multiple tests for each individual,
Input from the operation panel 10 such as data designating the data to be graphed, such as the data of the scoring results of the answers of all the students in one test is accepted.

Then, the designated data in the management data of the data storage unit 39 is converted into a predetermined format for the graph creating process which is a known technique and is expanded in the RAM 24 to perform the graph creating process. The created graph data can be output to the printer unit 200, and a graph as shown in FIG. 21, for example, can be printed on recording paper and output.

When the table key 13 on the operation panel 10 is selected, the table creation mode is set, and the table creation processing is performed for the data to be represented in place of the graph creation processing in the same procedure as in the graph creation mode described above. Thereby, for example, a table as shown in FIG. 22 can be printed on recording paper and output. In this way, it is possible to obtain the output of graphs and tables such as deviation values and history.

Next, when the question key 14 on the operation panel 10 is selected, the question paper creation mode is entered, and the question paper creation mode is selected, as shown in FIG.
The problem paper creation mode routine shown in (1) starts.
In this routine, first, the operator panel 10 inputs data desired by the question creator, such as inputting parameters for the questions, that is, outputting which questions of which level, what level, and what question.
Input from.

Then, the problem data corresponding to the input information is randomly selected from a number of problems registered in the data storage unit 39 in a designated number, and the problem data is transferred. , RAM24 or cache memory, and RAM2 in a predetermined format
Perform question drawing processing on 4.

Then, the data of the problematic paper thus drawn is sent to the printer section 200 to form an image on the recording paper and output it. Thereby, for example, a question sheet similar to the answer sheet shown in FIG. 20 can be obtained. If the required number is set in the same way as the number of copies when inputting parameters, the same problem paper will be printed for that number of sets.

When inputting parameters, an input method by reading a job sheet can be used. In that case, the image of the job sheet set by the scanner unit 100 is read, and the described character or bar code is recognized from the image data in the same manner as the recognition processing in the scoring mode and converted into code data. The designated number of question data to which a code matching the code is attached is randomly selected from the data storage unit 39 and expanded in the RAM 24. At this time, similar to the answer data, the question data is also compressed and stored, and is decoded when expanded in the memory.

In the data storage unit 39, necessary problem data is fetched and stored from the external image processing device 5, the external storage device 6, or the host 7. In addition, by selecting the registration key 15 on the operation panel 10, a problem paper registration mode is set, and a new problem paper is displayed on the scanner unit 100.
When the start key 18 is pressed after being set to, the image data is read and temporarily stored in the image memory 41 as in the case of the scoring mode, and the OCR is performed on the image data.
The unit 25 performs type recognition and ruled line recognition, converts it into a predetermined data format, stores it in the recognition result data area on the RAM 24, and registers it in the data storage unit 39.

This text data is stored in a storage medium such as a floppy disk or a magneto-optical disk of the external storage device 6 and loaded into a personal computer or the like to take in the stored data, or directly through a network. It is also possible to incorporate the answer data into a personal computer or the like and add the answer data to the registered data in the data storage unit 39.

Further, by using the marker recognition of the editing function, or by using a digitizer and using it, the answer portion and the question portion are recognized separately from the read image data of the question paper on which the correct answer is written, It is possible to register a new question paper and correct answer data for each question without editing operation on a personal computer. Then, the data of the newly registered question paper (excluding correct answer data) can be image-formed on the recording paper by the printer unit 200 to print a required number of question papers.

FIG. 23 is a flowchart showing the processing of the image processing apparatus 1 in the examinee registration mode. This routine starts by setting the examinee registration mode when the mode selection key 124 of the operation panel 10 and the "1" key of the numeric keypad 19 are pressed simultaneously, and first, the examinee information (whether or not there is an error in the scoring result) is set. (Discrimination information for determining)
Is input, and when the examinee information is input, it is recognized and stored in the data storage unit 39, and this processing ends.

The examinee information can be recognized by the image processing apparatus 1 by reading an image of the examinee registration sheet, a key operation signal from the operation panel 10, or a command from the host 7. For example, when the image of the examinee registration sheet 90 shown in FIG. 24 is read and the examinee information (actually read one page of image data) is recognized, the user scans it in the examinee registration mode. Set on the contact glass 101 of the part 100 and press the start key 18.

As a result, the image processing apparatus 1 reads the image of the examinee registration sheet 90 on the contact glass 101 by the scanner section 100 and inputs the image data, and the barcode recognition section 26 selects the barcode from the image data. When the OCR section 25 recognizes that the sheet read by recognizing 91 is the examinee registration sheet, the OCR section 25 gives the class name, the examinee No. ， Recognize the examinee's name.

The format of the examinee registration sheet may be stored in the data storage section 39, read out as needed, printed by the printer section 200 on the sheet, and output. Further, the examinee registration sheet is transferred from the document table 107 to the contact glass 10 of the scanner section 100.
It is also possible to automatically feed the image onto the device 1, read the image, and recognize the examinee information from the image data.

On the other hand, when the image processing apparatus 1 recognizes the examinee information by the key operation signal from the operation panel 10, the user depresses the examinee designation key 122 and presses the ten key 1
By inputting the examinee information at 9 or the like, the image processing apparatus 1 can recognize the examinee information.

FIG. 25 is a flow chart showing the processing of the image processing apparatus 1 in the recognition error examinee display mode. This routine is performed by the mode selection key 1 on the operation panel 10.
When the 24 key and the "2" key of the numeric keypad 19 are simultaneously pressed, the recognition error examinee display mode is set and started. First, it is determined whether or not the class name is input by the same operation as described above.

When the class name is input, it is judged whether or not the answer sheet is set on the original table 107. If the answer sheet is set, it is AD
The sheet is fed by F102 and set at the exposure position on the contact glass 101, the image of the answer sheet is read by the scanner section 100, the image data is subjected to image processing by the image processing section 21 as necessary, and the image memory 4 is read.
The image reading operation stored in 1 is performed.

Next, as described above, the image data of the answer sheet that has just been read is read from the image memory 41, the OCR unit 25 (and the barcode recognition unit 26) performs recognition processing on the image data, and the recognition result is obtained. The data is stored in the RAM 24 in a predetermined format. At the time of this recognition processing, the examinee information is also recognized. And
For the answer of the recognition result by the scoring processing unit 42,
Using the correct answer data stored in the data storage unit 39,
The scoring process is performed as described above, and the scoring result is stored in the RAM 24.

Subsequently, after the original request processing is performed as described above, it is judged whether or not the scoring mode is set, and if the scoring mode is still set, the process returns to the first step and the same as above. When the processing is performed and the setting of the scoring mode is canceled, the examinee information stored in the RAM 24 in the actual scoring and the examinee information (corresponding to the designated class name) registered in the data storage unit 39 are recorded. Matching is performed, and it is determined whether the two pieces of information do not match (whether or not the scoring result is incorrect).

Then, if the two pieces of information match, this processing is ended, but if they match, this processing is immediately ended, and if they do not match, that is, if there is an unscored answer sheet. The information about the examinee is retrieved from the data storage unit 39 and the information regarding the examinee is displayed on the LCD.
After displaying on 34 and notifying the user, this processing ends.

FIG. 26 is a flowchart showing the processing of the image processing apparatus 1 in the recognition error display mode. This routine is started by setting the recognition error display mode when the mode selection key 124 of the operation panel 10 and the “3” key of the numeric keypad 19 are simultaneously pressed.

Then, if the scoring mode is still set, the process returns to the first step to perform the same process as described above, and if the setting of the scoring mode is canceled, the process ends.

FIG. 31 is a flowchart showing the processing of the image processing apparatus 1 in the answer rewriting designation mode.
This routine is performed by the mode selection key 124 on the operation panel 10.
When the "7" key of the ten-key pad 19 is pressed at the same time, the answer rewriting specification mode is set and started. First, it is determined whether or not the answer sheet is set on the document table 107.

When the answer sheet is set, it is fed by the ADF 102 and set at the exposure position on the contact glass 101, the image of the answer sheet is read by the scanner section 100, and the image data is required. In response to this, an image reading operation is performed in which the image processing unit 21 performs image processing and stores it in the image memory 41.

Next, the image data of the answer sheet just read is read from the image memory 41, and the OCR section 25 (and the barcode recognition section 26) performs recognition processing on the image data, and then the recognition processing is properly performed. It is determined whether or not it has been performed (recognition OK), and if it has been performed properly, the scoring process is performed as described above, and then the destination of the answer sheet for which it is not necessary to rewrite the answer is determined.

Here, the discharge destinations in this case refer to a plurality of discharge trays attached to the printer unit 200 side, but only the discharge tray 219 is attached to the printer unit 200 side as shown in FIG. Has not been done. Therefore, here, it is assumed that the printer unit 200 is provided with a plurality of paper discharge trays.

Then, after the answer sheet from which the image data has been read by the scanner section 100 is conveyed toward the image forming position of the printer section 200, an image drawing process for drawing the scoring result data obtained by the scoring process is carried out. An image is formed on the answer sheet sent from the ADF 102 by the printer unit 200, and the scored answer sheet is discharged toward the discharge tray of the discharge destination determined earlier.

Then, the manuscript requesting process is performed, and the process proceeds to the judgment as to whether or not the scoring mode is set. If the scoring mode is still set, the process returns to the first step and the same process as described above is carried out. If the mode setting is canceled, the process ends.

On the other hand, if the recognition process cannot be performed properly, it is determined using the survey memory 40 whether or not there is an ambiguous part (answer column) in the answer data to be recognized, and the ambiguous part is identified. If there is, information about the data (recognition error data) at that location (problem or drawing position)
And the drawing position of the re-answer area data for rewriting the answer based on that information is determined, and then the destination of the answer sheet for which the answer needs to be rewritten is determined (for answer sheets that do not need to be rewritten, Different from the discharge destination).

Then, the answer sheet is transferred to the printer unit 200.
After the sheet is conveyed toward the image forming position, the drawing processing is performed to draw the re-answer area data (corresponding to the answer column) at the drawing position previously obtained, and the printer unit 200 AD
An image is formed on the answer sheet sent from F102, the answer sheet is discharged toward the discharge tray of the discharge destination determined earlier, and the same processing as described above is performed thereafter.

Note that the ambiguous portion is removed from the image data of the answer sheet read by the scanner section 100 to make it a re-answer area (blank area), and the image data is sent from the ADF 102 by the printer section 200. It is also possible to form an image on it.

As described above, according to this embodiment, when a normal copy document is set as the document and read by the scanner section 100, the read image data (image information) is temporarily stored in the image memory 41, Since the stored image data is image-formed on recording paper (paper) and is output, the required number of copies can be easily made as in the conventional digital copying machine.

If an answer sheet is set as a manuscript and read by the scanner section 100, the question and the answer to the question given there are recognized from the image information of the read answer sheet, and the recognized answer is data. Storage unit 39
Scoring is performed in comparison with the correct answer (or the correct answer based on the barcode described on the answer sheet) for the question that has been input or stored in advance, and the scoring result is output to the printer unit 200 to output the sheet or answer sheet. Since an image can be formed on a sheet or output to the LCD 34 for display, it is possible to automatically perform scoring simply by setting an answer sheet on which an answer is written.

Further, the following processings (1) to (6) can be performed to obtain various effects. (1) The examinee information (discrimination information) input and stored in the data storage unit 39 in advance and the examinee information of the scoring result stored in the RAM 24 are compared to determine whether or not they match (the scoring result is incorrect. If there is an answer sheet that has not been scored, it is possible to display information on the examinee on the LCD 34 and notify the user, so that it is possible to notify the user. Even if you set the answer sheet and automatically score it, if you forget to mark one of the answer sheets (if you want to feed multiple answer sheets one by one with ADF and make a score, by double feeding When it occurs), the user can immediately know it and automatically score the answer sheet.

(2) It is judged whether or not there is an unclear portion in the answer to be recognized in the image data of the answer sheet read by the scanner section 100, and if there is an unclear portion in the answer, Since the place can be displayed on the LCD 34 to notify the user, if there is an unclear place in the answer on the answer sheet and the appropriate scoring process is not performed, the place is immediately displayed. The answer sheet can be corrected and re-scored, and the quality of scoring can be improved.

(3) The unclear portion can be corrected on the LCD 34, and even if there is an unclear portion in the answer on the answer sheet and an appropriate scoring process is not performed, It is possible to improve the quality of scoring because the answer can be recognized and corrected, the subsequent scoring processing can be performed, and the result can be output.

(4) It is judged from the image data of the answer sheet read by the scanner section 100 whether or not the answer sheet can be scored, and only when the answer sheet can be scored, the answer sheet is printed by the printer section. Since the sheet can be conveyed to the image forming position of 200 and the scoring result can be output to the printer unit 200 to form an image on the answer sheet, only an accurate scoring result can be obtained. Also, even if you have mixed different types of answer sheets to be graded,
Since answer sheets and different types of sheets are automatically sorted from among them, the trouble of sorting by the user is saved and the work efficiency is improved.

(5) It is determined whether or not there is an ambiguous part in the answer to be recognized of the image data on the answer sheet read by the scanner section 100, and only when there is no ambiguous part in the answer. , The answer sheet to the printer unit 20
Since the image can be conveyed to the image forming position of 0 and the scoring result can be output to the printer unit 200 to form an image on the answer sheet, the same effect as described above can be obtained.

(6) It is determined whether or not there is an ambiguous part in the answer to be recognized of the image data on the answer sheet read by the scanner section 100, and only when there is an ambiguous part in the answer. , Image information (re-answer area data) indicating the re-answer area for rewriting the answer to the part is generated. Further, the answer sheet from which the image information is read can be conveyed to the image forming position of the printer unit 200, and the re-answer area data can be output to the printer unit 200 to form an image on the answer sheet. If there is an unclear part in the answer above and appropriate scoring processing is not performed, enter the correct answer in the re-answer area on the output answer sheet and then re-mark the answer sheet As a result, accurate scoring results can be obtained. Further, since the answer sheet which does not need to rewrite the answer and the answer sheet which needs the answer to be rewritten are discharged to different discharge trays, the sorting by the user is facilitated and the work efficiency is improved.

(7) The direction of the image information on the answer sheet read by the scanner section 100 is discriminated, the data of the scoring result is drawn in the discriminated direction, and the printer section 200 is drawn.
The image can be formed on the answer sheet conveyed to the image forming position of the printer unit 200.
Even if the answer sheet to be scored is set at the image reading position in an arbitrary direction, the scoring result can be image-formed in the correct direction on the answer sheet, and the work efficiency is improved.
