The image input unit 62 controls the exchange of information with the reading device 30 and gives operation control instructions. The image input unit 62 inputs image data of the test material 70 through the reading device 30 that scans the test material 70 to be read and reads the image data.
The reading device 30 is configured using, for example, a contact image sensor that generates image data (scan data) of the test material 70 by optically reading the image of the test material 70 . .

The database section 63 holds and accumulates various data. The database unit 63 is configured using a storage device such as a hard disk, for example, and has a function of processing (reading, updating, deleting, searching, etc.) the accumulated data in addition to the function of accumulating data. In the database unit 63, as information about the test material 70, for example, original image data, test material identification information, and layout information of the test material 70 and 70A shown in FIGS. attached and registered.

As shown in FIGS. 15, 16, and 17, the original image data of the test materials 70 and 70A are the original unfilled data in which nothing is written (added) in the answer columns 71 and 71A and the answerer information column 72. It is the image data of the test materials 70 and 70A in the state. The original image data of the test materials 70 and 70A are recorded on a recording medium and provided by, for example, the educational material sales maker that created the test materials 70 and 70A. Alternatively, the image data obtained by reading the images of the blank test materials 70 and 70A with an externally connected scanner device or the reading device 30 or the like attached to the device body may be registered in the database section 63. good.

The image processing section 50 performs various image processing using the image data input by the image input section 62 . The image processing unit 50 according to the present embodiment has a normal print image data generation function, and also a test material scoring function and an image processing function, as shown in FIG. 52 , an incorrect answer position specifying unit 53 , a teaching material data generating unit 54 , and a management information extracting unit 55 .

The answerer information extraction unit 51 extracts answerer information from read image data. The answerer information is written in the answerer information column 72 by the learner taking the test with a pencil or the like. The image data of the test material 70 thus obtained is compared with the answerer data stored in the database unit 63, and the answerer information is extracted from the difference data.
Further, the answerer information may be extracted as bitmap format image data extracted from the answerer information column 72 as it is, or may be extracted as text data obtained by OCR processing the extracted image data. If the answerer information is extracted as image data in bitmap format, the answerer can be uniquely identified based on the image pattern or image characteristics.

The correctness determination unit 52 determines whether the answers entered in the answer columns 71 and 71A are "correct (o)" or "wrong (x)". Specifically, for example, the image shape of the answer written with a pencil or the like in the answer columns 71 and 71A is recognized, and the recognized image shape is pattern-matched with, for example, a pre-registered “correct” shape. As a result, if the shape is similar to the "correct" shape, it is determined to be "correct (○)", and if it is not similar to the "correct" shape, it is determined to be "wrong (x)".

As a result of pattern matching, if it is not possible to determine "correct" or "incorrect", the system control device 60 transmits the image data read by the reading device 30 to the user (grader) via the communication line 82, After that, the scoring result scored by the user is obtained and used as the scoring result. Examples of cases where "correct answer" or "incorrect answer" cannot be determined include a reading error in the reading device 30, a descriptive answer, an incomplete answer in which partial points are allocated, and the like.

The incorrect answer position specifying section 53 specifies the positions of the answer columns 71 and 71A determined as incorrect answers. Specifically, the answer determined as incorrect by the correctness determination unit 52 is selected from the position information (coordinate data) of the answer column 71 included in the layout information of the test materials 70 and 70A registered in the database unit 63. By reading the position information of the column or by reading the position information of the other answer columns other than the answer column determined as correct by the correctness determination unit 52, the position of the incorrect answer column can be specified.

FIG. 19 shows a specific example of test material on which the scoring results are additionally printed for retesting. In the automatic scoring device 1 according to the present embodiment, only the answer columns 71 and 71A in which the correct answer is entered are marked with a circle, and the answer column 71 in which the incorrect answer is entered. , and 71A are additionally printed so as not to be marked with an "X" (see the broken line area in FIG. 19). As a result, the learner can retake the test using the test materials 70 and 70A in which the learner once filled in the answers for the incorrect answers.

The teaching material data generating unit 54 generates image data of the test teaching materials 70 and 70A including questions corresponding to the incorrect answer columns whose positions are specified by the incorrect answer position specifying unit 53 .
The teaching material data generation unit 54 performs a process of converting the incorrect answer column to the original blank state. As a specific method of the conversion process, image data is generated so that the inside of the answer column in which the incorrect answer is entered is filled with an image of the same color as the ground color of the test material 70, 70A. As a result, the incorrect answer column can be blanked in accordance with the background color of the test materials 70, 70A so that the learner can take the test again using the test materials 70, 70A in which the answers have been written once. .

In addition, the educational material data generation unit 54 whitens the answer columns of the incorrect answers whose positions have been identified by the incorrect answer position identification unit 53 in the image data input by the image input unit 62, and produces images of the test materials 70 and 70A. Generate data. As shown in FIG. 20, the generated image data is printed on a new sheet of paper P by the image forming unit 10 via the print control unit 61, and when the test materials 70 and 70A are damaged, the incorrect answer column is printed. can be left blank to allow retesting.

In addition, if the image data input by the image input unit 62 is the first image data of the test material 70 or 70A, the teaching material data generation unit 54 generates management information to be extracted by the management information extraction unit 55. A QR code (registered trademark) as an example is generated as a two-dimensional code pattern. By adding a QR code (registered trademark) to the test materials 70 and 70A, the scoring results can be managed for each learner. In addition, when a QR code (registered trademark) is added to the test materials 70 and 70A, when reading the test materials 70 and 70A with the reading device 30, the OCR processing for the correct answer columns 71 and 71A read last time is you can avoid doing it. Thereby, the accuracy of scoring can be improved.

FIG. 21 shows a specific example of test materials on which the scoring results are printed for retesting. If the image data input by the image input unit 62 is the image data of the test material 70, 70A for the second time or later, the teaching material data generation unit 54 superimposes a strikethrough on the previous score of the test material 70, 70A. In addition to generating image data, image data is generated so that the current score is additionally printed in the vicinity of the area where the previous score was printed.
In addition, when the grading result is improved from the previous grading result, the teaching material data generation unit 54 generates image data so that the score can be printed with a larger score than the previous grading result. is the full score, image data is generated so that additional printing can be performed with a larger score than when the score is less than the full score.
Further, the teaching material data generation unit 54 may generate image data so as to additionally print the average score of the class to which the learner belongs and the rank of the learner in the class.
As a result, it is possible to provide information that enhances the learner's willingness to study using the test materials 70 and 70A.

The educational material data generation unit 54 generates image data so that the image data to be additionally printed is printed in a color different from that of the previous time. Specifically, the learning effect of the learner can be further enhanced by additionally printing the judgment mark indicating the correct answer, the judgment mark indicating the incorrect answer, and the score in colors different from those of the previous time.

If the current grading result is not full, the teaching material data generation unit 54 generates and prints image data of new test materials from among the test materials registered (accumulated) in the database unit 63. Generate image data as follows. As a result, it is possible to provide additional test materials to learners whose marks were not perfect.

In the case of a question for which the answer cannot be determined uniquely, the teaching material data generation unit 54 generates image data by adding an object image specifying the answer column to the image data input by the image input unit 62 . The image data generated by adding the object image is transmitted by the system control device 60 to the user (grader) via the communication line 82 . Thereby, the user (grader) who acquired the image data can easily recognize the answer column.

The data management section 64 uses the database section 63 to manage various data. As one of the management items, the data management unit 64, for each learner classified by the answerer information, for each of a plurality of questions included in the test materials 70 and 70A, for example, the corresponding answer columns 71, The number of test executions (the number of re-tests) performed until the correct answer is entered in 71A and the score for each test are managed as a management table.
The management table is registered in the database unit 63 for each learner specified by the answerer information (the grade and name of the learner, etc.).

In the automatic scoring devices 1, 1A, and 1B having such a functional configuration, test materials are registered in the database section 63, and the user (teacher, etc.) prints them as test materials in the image forming section 10 as needed. can be used The test materials 70 and 70A in which answers have been entered in the answer columns 71 and 71A by learners (students, etc.) are read by the reading device 30, and the image processing unit 50 displays incorrect answer columns in the test materials 70 and 70A. image data is generated so that the grading results with the blanks can be additionally printed.
