Description

  The present invention relates to a terminal device for writing characters in a specific area, for example, correction of answer contents using an electronic pen, a program thereof, and a correction support system.

  In the communication correction service generally provided, a communication correction company mails an answer sheet on which a problem is printed to a student, and the student enters the answer on the answer sheet and returns it to the communication correction company. Then, when the communication correction company collects several answer sheets and mails them to the correction person, the correction person directly writes the correction comments on the answer sheet and returns it to the communication correction company. The communication corrector returns the answer sheet with the received correction comments to the student. For this reason, the answer sheet must be reciprocated between the student, the communication corrector, and the corrector many times, so the student returns the answer sheet to the communication corrector and receives an answer sheet with correction comments. By the time, there was a problem that it took more than a few weeks.

  On the other hand, various systems for converting handwritten information into electronic data using an electronic pen have been realized. For example, as an electronic pen that can be used in the same manner as writing on paper, Anoto pen developed by Anoto in Sweden is well known. Anotopen is used with dedicated paper on which a predetermined dot pattern is printed.

  At the tip of the anotopen, there are an ink cartridge and a miniature camera. A processor and a data communication unit are mounted inside the pen. Users can write letters on an exclusive paper with anotopen. At that time, as the pen moves, the dot pattern printed on the dedicated paper is photographed with a micro camera. Based on the captured dot pattern, the position coordinates on the dedicated paper are acquired. In this way, Anoto Pen takes the information written on the special paper with the micro camera at the tip of the pen into the pen as digital information, and the acquired position coordinates etc. are transferred to a nearby personal computer or mobile phone terminal device using a data communication unit. Send. Entry information such as characters and images written by the user is recognized by the terminal device based on continuous position coordinates (Patent Document 1).

  Patent Document 2 listed below is disclosed as a test scoring system using such an Anoto electronic pen system. According to the system described in Patent Document 2, the answer is written on the answer sheet on which the dot pattern is printed, and when scoring the contents of the answer, “○” if the answer is correct, or a semi-correct answer that is given a partial point. For example, “△” and the number of the partial point, or “×” if incorrect, are entered on the answer sheet with an electronic pen, and the terminal device is made to recognize the score content.

  Further, Patent Document 3 below proposes an online test system using an electronic pen that can read a unique dot pattern. In this online test system, a terminal device, a printer, and an electronic pen are prepared for both a person who takes the test and a person who scores the answer contents. Then, on the examinee side, an answer sheet having pattern data is printed by a printer, and the answer is entered using an electronic pen. The entry information generated by the electronic pen is transmitted to the grader side terminal device via the wireless communication network and the Internet via the terminal device (mobile phone). On the grader side, in response to an instruction from the terminal device, the printer prints an answer sheet including pattern data and answer contents, and the scorer writes the score contents on the answer sheet using an electronic pen. The entry information generated with the electronic pen is transmitted to the terminal device on the examinee side through the Internet and the wireless communication network via the terminal device on the grader side. On the examinee's side, the printer prints an answer sheet on which the scoring content is displayed in accordance with an instruction from the terminal device. Thereby, the examinee can acquire the graded answer sheet.

  Correspondence education systems that can be corrected with an electronic pen based on another principle have also been proposed. In the correspondence education system described in Patent Document 4 below, when an answer is written on paper with a pen attached with an ultrasonic transmitter, the receiving unit detects the position of the pen tip and recognizes the handwritten input handwriting. The handwritten data is transmitted to the corrector's terminal through the Internet. Similarly, at the corrector's terminal, when the correction content is written on the paper with a pen equipped with an ultrasonic transmitter, the receiving unit detects the position of the pen tip and recognizes the handwritten input, and then writes the handwritten data. Generate. The handwriting input device may be a tablet or the like that can be input on a liquid crystal display.

  In the correction management system described in Patent Document 5, an answer sheet in which an answer is written is read by a scanner to generate image data, which is sent to a correction terminal via a network. In addition, it is described that the correction person enters the correction contents directly on the liquid crystal display with a pen in a state where the image data is displayed on the liquid crystal display such as a touch panel on the correction terminal.

Japanese translation of PCT publication No. 2003-511761 Japanese National Patent Publication No. 2005-104060 Japanese Patent No. 37367533 Japanese Patent No. 3810747 JP 2008-46398 A

  In the system according to Patent Document 2, the answer content is scored by entering symbols such as “○”, “△”, and “×” on the answer sheet with an electronic pen according to the correct answer, semi-correct answer, and incorrect answer. It does not require a large space for scoring. On the other hand, when correcting the content of an answer, whether it is a correct answer, a semi-correct answer, or an incorrect answer, as well as a way of thinking about the problem and important points for learning in order to improve the learning efficiency of the examinee Write a comment. In such a case, in order to write a correction comment, a certain amount of margin is required on the answer sheet, and for the sake of clarity, write the correction comment so that it does not overlap with the answer area of the examinee. There is a need.

  In addition, as in the online test system according to Patent Document 3, a correction service is provided to a large number of examinees in order to provide a terminal device, a printer, and an electronic pen to both the examinee and the grader. It is not realistic for a communication correction company because it requires a large initial cost.

  In the correction management system of Patent Document 4 described above, it is necessary to provide an ultrasonic pen, a receiving unit, etc. for both the examinee and the grader, and communication that provides correction services to a large number of examinees. It is expensive and impractical for the corrector. Of course, the same applies to tablets and the like proposed as another principle. In addition, in the liquid crystal display tablet proposed in Patent Document 5 and Patent Document 4, the resolution for recognizing the position of the pen tip is low, and if the character to be written as the correction content is written small, the character is crushed, and the correction is made. There is also a risk that characters cannot be recognized.

  Therefore, the present invention, on the display screen, in advance, after designating the area where the entry contents such as correction comments are to be displayed, the terminal apparatus can be displayed by applying the entry contents entered with the electronic pen to the designated area, The purpose is to provide the program and correction support system.

<First Embodiment>
[Outline of the configuration and usage of the correction support system]
FIG. 1 shows a correction support system 1 according to the first embodiment. As shown in FIG. 1, a correction support system 1 includes a scanner 2 and a center server (central processing unit) 3 used by a communication correction company, a terminal device (terminal device) 4 for a corrector used by the correction operator, and an electronic pen. 6 and a sheet (paper) 7 for the corrector. The center server 3 and the terminal device 4 are connected via the Internet 8.

  In such a configuration, the communication correction company mails the answer sheet 9 on which the problem is printed to the student, and the same contents as the answer sheet 9 and a coded pattern that can be read by the electronic pen 6 are printed. The corrector paper 7 is mailed to the corrector. The student enters the answer on the answer sheet 9 with a pencil or pen and returns it to the communication correction company. The communication correction company causes the scanner 2 to read the received answer sheet 9 as image data, and stores the image data in the center server 3 for centralized management. Further, the communication correction operator operates the center server 3 to transmit the image data read by the scanner 2 to the terminal device 4 via the Internet 8. The center server 3 includes a processor such as a CPU, a display, a hard disk, a memory such as a ROM, a RAM, a network communication device, and the like as hardware, but a personal computer may be used.

  The terminal device 4 displays the received image data on a display screen of a display (display means). The correction person enters the correction comment on the correction person sheet 7 using the electronic pen 6 while referring to the display screen of the terminal device 4. The electronic pen 6 reads the dot pattern (encoded pattern) 11 printed on the paper 7 when filling in the corrector paper 7, calculates the position coordinates reflecting the handwriting, and includes the position coordinates. The entry information is generated and transmitted to the terminal device 4. In a state where the image data of the answer sheet 9 on which the answer is written is displayed, the terminal device 4 displays the entry contents of the entry information received from the electronic pen 6 on the screen. In this way, the corrector uses the electronic pen 6 to write the correction comments on the image data of the terminal device 4 in an overlapping manner. Hereinafter, the correction person paper 7, the electronic pen 6, and the terminal device 4 will be described in detail.

[Corrector paper]
With reference to FIG. 2, the corrector paper (paper) 7 will be described. As shown in FIG. 2, an Anoto dot pattern (coded pattern) 11 indicating position coordinates is printed on almost the entire surface of the sheet 7, and a class entry field, a name entry field, a problem, etc. 12 is printed in the same arrangement as the answer sheet 9. Further, on the sheet 7, grids 13 are printed in a grid pattern with broken lines, which are used as a guideline for the size and position of characters when writing correction comments or the like. The dot pattern 11 is printed with ink containing carbon that absorbs infrared rays, and the characters 12 such as problems are printed with ink that does not absorb in the infrared region.

[Dot pattern]
Next, an Anoto dot pattern (coded pattern) 11 printed on the paper 7 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram illustrating the relationship between the dots of the dot pattern 11 printed on the paper 7 and the values to which the dots are converted. As shown in FIG. 3, each dot of the dot pattern 11 is associated with a predetermined value depending on its position. In other words, each dot is associated with a value of 0 to 3 depending on which direction the top, bottom, left, or right is shifted from the reference position of the grid (intersection of the vertical line and horizontal line). The value of each dot can be further converted into a first bit value for the X coordinate and a second bit value for the Y coordinate. The position coordinates on the paper 7 are determined by the combination of the information thus associated.

  FIG. 4 shows an arrangement of a certain dot pattern. As shown in FIG. 4A, 6 × 6 dots are arranged in a range of about 2 mm in length and width so that a unique pattern is obtained no matter what portion of the paper 7 is taken 6 × 6 dots. ing. The dot pattern formed by these 36 dots holds position coordinates and a dot pattern address (coded pattern address). FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a corresponding value based on the regularity shown in FIG. 3 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 6 that captures an image of the dot pattern 11.

[Electronic pen]
Next, the electronic pen 6 will be described with reference to FIG. As shown in FIG. 5, the electronic pen 6 includes a processor 608 including a CPU, a memory 609 such as a ROM and a RAM, a communication unit including an antenna, a transmission circuit, and the like inside a housing 601. 611, a battery 612, an LED 605, a CMOS camera 606, a real-time clock 610, a pressure sensor 607, and an ink cartridge 604. The tip of the ink cartridge 604 is a pen tip 603, and the corrector can enter a correction comment on the answer while the pen tip 603 of the electronic pen 6 is in contact with the paper 7.

  The battery 612 is for supplying power to each component in the electronic pen 6. For example, the attachment / detachment of the cap containing the magnet is detected by a magnetic sensor (not shown), and the power supply of the electronic pen 6 itself is turned on / off. The real-time clock 610 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 608. The pressure sensor 607 detects the pressure applied through the ink cartridge 604 from the pen tip 603 when the corrector writes characters on the paper 7 with the electronic pen 6, that is, the writing pressure, and sends the value to the processor 608. .

  The processor 608 switches on / off the switches of the LED 605 and the CMOS camera 606 based on the writing pressure data provided from the pressure sensor 607. That is, when the corrector writes characters or the like on the paper 7 with the electronic pen 6, the pen pressure is applied to the pen tip 603, and when the pressure sensor 607 detects a writing pressure of a predetermined value or more, the processor In step 608, it is determined that the correction person has started entry, and the LED 605 and the CMOS camera 606 are operated.

  The LED 605 and the CMOS camera 606 are attached in the vicinity of the pen tip portion 603 of the electronic pen 6. An opening 602 is formed in a portion of the housing 601 that faces the LED 605 and the CMOS camera 606. The LED 605 emits infrared rays toward the vicinity of the pen tip portion 603 on the paper 7. The region is slightly shifted from the position where the pen tip 603 contacts the paper 7. The CMOS camera 606 captures the dot pattern 11 in the area illuminated by the LED 605 and supplies image data of the dot pattern 11 to the processor 608. An imaging region by the CMOS camera 606 is a range including a size of about 2 mm × about 2 mm as shown in FIG. Imaging by the CMOS camera 606 is performed about 50 to 100 times per second.

  Since carbon absorbs infrared rays, the infrared rays irradiated by the LED 605 are absorbed by the carbon contained in the dots. Therefore, the dot portion has a small amount of infrared reflection, and the portion other than the dot has a large amount of infrared reflection. By discriminating the photographing result of the CMOS camera 606 with a threshold value, it is possible to distinguish the dot region containing carbon from the other region by the difference in the amount of reflected infrared light. Since the ink printed with characters and the like on the paper 7 does not have absorbability in the infrared region, the dot pattern 11 can be reliably recognized.

  The processor 608 continues the XY coordinates (position coordinates) on the sheet 7 of the stroke (handwriting) to be written by the correction person from the dot pattern 11 of the image data supplied by the CMOS camera 606 while the correction person is writing. Will be calculated. That is, the processor 608 converts the image data of the dot pattern 11 supplied by the CMOS camera 606 into a data array as shown in FIG. 4B, and further converts it into an X coordinate bit value and a Y coordinate bit value. Then, the XY coordinate data and the dot pattern address are calculated from the data array by a predetermined calculation method. The processor 608 then transmits the current time (time stamp: entered time information) transmitted from the real-time clock 610, writing pressure data, dot pattern address, XY coordinate data, and pen ID (electronic pen identification information). Associate. Since the 6 × 6 dot pattern on the sheet 7 does not overlap within the sheet 7, when the correction person enters a correction comment with the electronic pen 6, the position on the sheet 7 where the written position corresponds. Can be specified by coordinate calculation by the processor 608.

  The memory 609 stores a pen ID for identifying the electronic pen 6 and stores entry information generated by the processor 608.

  The communication unit 611 transmits entry information in which time information (time stamp), writing pressure data, dot pattern address, XY coordinate data, and pen ID are associated with each other to the terminal device 4. Transmission by the communication unit 611 is immediately and sequentially performed to the terminal device 4 by a Bluetooth (registered trademark) wireless transmission method.

  The electronic pen 6 generates entry information and transmits it to the terminal device 4 every time the corrector fills in the sheet 7. For example, when the corrector makes an entry by bringing the pen tip 603 of the electronic pen 6 into contact with the paper 7 (pen down), the electronic pen 6 detects that the pressure sensor 607 detects a writing pressure of a predetermined value or more. A contact with the sheet 7 is detected. The dot pattern 11 in the vicinity of the pen tip portion 603 is photographed by the CMOS camera 606 while irradiating the infrared rays with the LED 605. The processor 608 calculates the XY coordinate data and the dot pattern address at the contact position on the paper 7 from the image data of the captured dot pattern 11. The processor 608 generates entry information in which the time information indicating the current time transmitted by the real-time clock 610, the dot pattern address, the XY coordinate data, the writing pressure data, and the pen ID are associated with each other. The data is transmitted to the terminal device 4 by the communication unit 611.

  As described above, the electronic pen 6 continues to generate entry information and transmit it to the terminal device 4 while the corrector continues to fill in the form 7. Then, when the corrector removes the electronic pen 6 from the paper 7 (pen up), the electronic pen 6 stops the entry because the pressure sensor 607 no longer detects a writing pressure of a predetermined value or more. Is determined. Then, the LED 605 and the CMOS camera 606 are stopped, and transmission of entry information to the terminal device 4 is stopped.

A tool box 52 in which convenient symbols and characters can be input is displayed. The corrector can recognize from the display of the image 51 which area is blank and the corrective comment can be added. Also, as shown in FIG. 9, the corrector uses the tool box 52 to display correction symbols such as a number indicating a partial point, a number 53 for footnotes, and a comment insertion position symbol 54 by the processing of the processing means 48. It can be selected and input as appropriate by operation.

  Subsequently, as shown in FIG. 10, the corrector designates a rectangular area 56 to which the correction comment is to be added in the blank of the image 51 by dragging the mouse. At this time, the area designating unit 42 recognizes the area 56 designated by the mouse drag operation and transmits it to the processing unit 48. The processing unit 48 moves the cursor 57 in accordance with the drag operation and moves the designated area. 56 is displayed so as to be surrounded by a broken line (step S102). Here, the corrector performs a drag operation with the mouse in a state where the image 51 of the answer sheet 9 is displayed, so that the corrector comment is added so as not to overlap the area where the question sentence or the answer is displayed. The designated area 56 can be designated.

  When the designated area 56 is determined, the processing means 48 determines the paper 7 that can be input to the designated area 56 from the vertical and horizontal lengths of the designated area 56 and the vertical and horizontal lengths of one square 13 in the paper 7 as shown in FIG. The number of vertical grids 13 (the number of characters) or the total number of characters is calculated and displayed on the pop-up window 58 (step S103). Here, the processing means 48 obtains the value of the quotient when the vertical length / horizontal length of the designated area 56 is divided by the vertical length / horizontal length of the square 13 of the paper 7 as the number of cells that can be input, and calculates the number of characters that can be input. In this case, it is determined by the product of the vertical and horizontal quotients. Therefore, if the corrector only writes correction comments one character at a time using the check marks 13 on the paper 7 within the range of the check marks 13 or the number of characters, the characters written by the electronic pen 6 are partially displayed. The correction comment can be displayed in the designated area 56 without being hidden.

  Then, unless the processing means 48 detects double tap entry information on the paper 7 by the electronic pen 6 indicating the end of character input (step S104: No), it is received from the electronic pen 6 as shown in FIG. The entry information is sequentially recognized and converted into text data, and the text data 59 is inserted into the designated area 56 and displayed (step S105). Here, when the processing means 48 recognizes that the number of characters that can be inserted into the designated area 56 exceeds the number of characters that are transmitted from the electronic pen 6 and converted into text data (step S106: Yes), as shown in FIG. Then, the pop-up window 61 displays that there are too many characters to be inserted (step S107), and returns to step S104. As a result, the corrector can optimize the designated area 56 and the number of characters in the correction comment by a drag operation using the mouse of the area designating unit 42. On the other hand, the processing means 48 repeats steps S104 to S106 while the number of characters that can be inserted into the designated area 56 does not exceed the number of characters that are transmitted from the electronic pen 6 and converted into text data (step S106: No). Sequentially, the entry information is converted into characters, and the text data is inserted into the designated area 56 and displayed. As shown in FIG. 14, in order to make it easier to see that the comment is a correction comment, the designated area 56 may be displayed surrounded by a solid line by the processing of the processing means 48. At this time, the processing means 48 displays on the tool box 52 a control button 521 that enables selection of a flower frame, a dotted line, etc. so that the corrector can change the design of the frame line of the correction comment.

  When the corrector finishes writing a correction comment for a piece of paper 7 using the electronic pen 6 and causes the terminal device 4 to recognize the end of character input, when the electronic pen 6 is double-tapped on the paper 7, the terminal device 4 The double-tap entry information is received from the electronic pen 6 and it is recognized that the double-tap has been made (step S104: Yes). If the processing unit 48 detects that the next region designation for adding the correction comment is subsequently made (step S108: Yes), the processing unit 48 returns to step S102 and repeatedly executes steps S102 to S108. On the other hand, when the next area is not designated for a predetermined time and the entry of the correction comment is completed (step S108: No), the processing means 48 adds the correction comment and the correction added by using the tool box 52 together with the image data. Information such as symbols is stored in the storage means 46 together with the arrangement information in the image data (step S109).

[Return of correction data]
After the correction comment is added to the image data by the correction comment entry function and stored in the storage means 46, the data is transmitted to the center server 3 by the network communication means 44 by the processing of the processing means 48. When the communication correction company receives the image data with the correction comment at the center server 3, it prints the image data and returns it to the student by mail or the like.

[Effects of First Embodiment]
As described above, according to the correction support system 1 according to the first embodiment, since the image 51 of the image data of the answer sheet 9 in which the answer contents are written is displayed on the display screen of the display means 47, From the display of the image 51, it is recognized which area is blank and the correction comment can be attached, and the correction comment is made so as not to overlap the area where the question or the answer is displayed by dragging the mouse. Can be designated (see FIG. 10). Further, the processing means 48 calculates the number of characters or the total number of characters in the vertical and horizontal squares 13 on the paper 7 that can be entered in the designated area 56 and displays the value in the pop-up window 58 (see FIG. 11). In the range of the number of characters, if a character is entered on the paper 7 using the cell 13, the correction comment is displayed in the designated area 56 without partially hiding the character entered by the electronic pen 6. Can do. When the processing unit 48 recognizes that the number of characters that can be inserted into the designated area 56 exceeds the number of characters that are transmitted from the electronic pen 6 and converted into text data, the pop-up window 61 indicates that there are too many characters to be inserted. (See FIG. 13), the corrector can optimize the designated area 56 and the number of characters in the correction comment by dragging the mouse of the area designating means 42.

  Further, according to the correction support system 1 of the first embodiment, for the communication correction company, the scanner 2 and the center server 3 of the communication correction company and the terminal of the correction person are provided without supplying any apparatus to the student. The system can be constituted by the apparatus 4, the electronic pen 6, and the paper 7, and the initial investment is light. Conventionally, the time required for the communication correction company to mail the answer sheet 9 of the student directly to the corrector and return it after the correction is converted into the electronic data of the answer sheet 9, the conversion comment electronic data, It can be greatly shortened by electronic data transmission.

Second Embodiment
Next, a second embodiment will be described. Parts similar to those in the second embodiment and the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate. The difference between the second embodiment and the first embodiment is that, in the first embodiment, the processing means 48 recognizes the input information and converts it into text data and then displays it in the designated area. In the second embodiment, in order to reflect the taste of the corrector character as it is, the stroke data reflecting the handwriting is reproduced and displayed as an image without performing character recognition.

  In the second embodiment, the processing means 48 recognizes the area 56 specified by the drag operation using the mouse of the area specifying means 42, surrounds it with a broken line, and displays correction comments that can be displayed in the specified area 56. The amount (vertical / horizontal size) is converted into the number of vertical / horizontal cells 13 on the paper 7 matching the designated area 56 and displayed on the display means 47. The processing unit 48 reproduces the stroke data as an image from the entry information sequentially transmitted by the electronic pen 6 until the end of the character input indicated by the entry information such as a double tap is recognized, and the designated area 56 to display. At this time, the processing means 48 reduces the handwritten character correction comment by the stroke data of the entry information received from the electronic pen 6 so that it fits in the designated area 56, and inserts the image data by applying it to the designated area 56. Display.

  Even if the corrector writes a character using the grid 13 as a guide, the character entered from the grid 13 may protrude from the grid 13 or may be small. Therefore, as shown in FIG. 15A, the processing unit 48 reduces the handwritten character based on the XY coordinate data included in the entry information so as to include the entire stroke of the handwritten character of the correction comment. Find the circumscribed frame. Specifically, the processing means 48 sets the vertical line passing through the position (Xmin, Yn) where the X coordinate is minimum among the stroke XY coordinates of the handwritten character as the left line of the rectangle, and the position where the X coordinate is maximum (Xmax). , Yn) is a perpendicular line on the right side of the rectangle, a horizontal line passing through the position where the Y coordinate is minimum (Xm, Ymin) is a line below the rectangle, and a horizontal line passing through the position where the Y coordinate is maximum (Xn, Ymax) Find a rectangle with a line above the rectangle. If the circumscribed rectangle is larger than the designated area 56, the processing means 48 reduces the stroke data at a reduction ratio that fits in the designated area 56, and reproduces it as an image of a handwritten character correction comment. 56 to display. At this time, when the processing unit 48 recognizes that the reduction ratio has been determined in advance and exceeds a predetermined value stored in the storage unit 46, the processing unit 48 displays on the display unit 42 that there is too much correction comment to be inserted. As a result, the corrector can optimize the designated area 56 and the amount of the correction comment and the entry range.

  The circumscribing frame is not limited to the rectangle as shown in FIG. 15A, and the processing means 48 obtains a circumscribing rectangle for each handwritten character as shown in FIG. A polygon that includes a rectangle may be obtained, or a curve such as an ellipse as shown in FIG. Further, when the circumscribed rectangle is smaller than the designated area 56, the processing means 48 may enlarge the stroke data at an enlargement ratio that matches the designated area 56.

[Correction comment entry function]
Next, with reference to the flowchart of FIG. 16 and the display screen example of FIG. 17, the correction comment function using the electronic pen 6 by executing the dedicated application of the second embodiment will be described.

  First, the processing means 48 displays the image 51 of the image data of the answer sheet 9 on which the answer contents of the student are written on the display screen of the display means 47 (step S201) and also displays the tool box 52. The corrector uses the tool box 52 to select and input correction symbols such as a number indicating a partial point, a number 53 for footnotes, and a comment insertion position symbol 54 as needed by a mouse operation by the processing of the processing means 48. Can do. Subsequently, the corrector designates a rectangular area 56 to which a correction comment is to be added in the blank of the image 51 by dragging the mouse. At this time, the area designating unit 42 recognizes the area 56 designated by the mouse drag operation and transmits it to the processing unit 48. The processing unit 48 moves the cursor 57 in accordance with the drag operation and moves the designated area. 56 is displayed so as to be surrounded by a broken line (step S202). Here, the corrector performs a drag operation with the mouse in a state where the image 51 of the answer sheet 9 is displayed, so that the corrector comment is added so as not to overlap the area where the question sentence or the answer is displayed. The designated area 56 can be designated.

  When the designated area 56 is determined, the processing means 48 determines the size of the vertical and horizontal grids 13 on the paper 7 that can be displayed in the designated area 56 from the vertical and horizontal lengths of the designated area 56 and the vertical and horizontal lengths of the grid 13 on the paper 7. The number (size) is calculated and displayed on the pop-up window 58 (step S203). Here, the processing means 48 obtains the value of the quotient when the vertical and horizontal lengths of the designated area 56 are divided by the vertical and horizontal lengths of the grid 13 of the paper 7 as the number of grids that can be displayed. Therefore, if the corrector writes correction comments one character at a time using the check marks 13 on the paper 7 within the range of the check marks 13, the characters written by the electronic pen 6 are not reduced. The correction comment can be displayed in the designated area 56. Then, unless the processing means 48 detects double-tap entry information on the paper 7 by the electronic pen 6 indicating the end of character input (step S204: No), the handwritten character is sequentially obtained from the entry information received from the electronic pen 6. A rectangular circumscribed rectangle including the entire stroke is obtained (step S205).

  Subsequently, when the circumscribed rectangle is larger than the designated area 56, the processing means 48 reduces the stroke data at a reduction ratio that fits in the designated area 56 (step S206). Then, the correction comment of the handwritten character is reproduced as an image, and the image data is inserted into the designated area 56 and displayed as shown in FIG. 16 (step S207). Here, when the processing means 48 recognizes that the reduction ratio of the stroke data has exceeded a predetermined value (step S208: Yes), a pop-up window 61 (see FIG. 13) indicates that there is too much correction comment to be inserted. (Step S209), and the process returns to step S204. As a result, the corrector can optimize the designated area 56 and the amount of the correction comment by the drag operation using the mouse of the area designating unit 42. On the other hand, while the reduction rate of the stroke data does not exceed the predetermined value (Step S208: No), the processing unit 48 repeats Steps S204 to S208, sequentially reducing the stroke data, and the image of the handwritten character of the correction comment And is inserted into the designated area 56 and displayed. As in the first embodiment, in order to make it easier to see that the comment is a correction comment, the processing of the processing means 48 may display the designated area 56 with a solid line so that it can be easily seen.

  When the corrector finishes writing a correction comment for a piece of paper 7 using the electronic pen 6 and causes the terminal device 4 to recognize the end of character input, when the electronic pen 6 is double-tapped on the paper 7, the terminal device 4 Then, it receives double-tap entry information from the electronic pen 6 and recognizes that it has been double-tapped (step S204: Yes). If the processing unit 48 detects that the next region designation for adding the correction comment is subsequently made (step S210: Yes), the processing unit 48 returns to step S202 and repeatedly executes steps S202 to S210. On the other hand, when the next area has not been designated for a predetermined time and the entry of the correction comment is completed (step S210: No), the processing means 48 includes the image data of the correction comment and the tool box 52 together with the image data of the answer sheet 9. Is stored in the storage unit 46 together with the arrangement information in the image data of the answer sheet 9 (step S211).

[Effects of Second Embodiment]
According to the correction support system 1 according to the second embodiment, as in the operation and effect of the correction support system 1 according to the first embodiment described above, the corrector can determine which area is blank from the display of the image 51. Recognizing whether a correction comment can be attached, it is possible to designate a designation area 56 into which a correction comment is inserted so as not to overlap the area where the question or answer is displayed (see FIG. 10).

  Further, according to the correction support system 1 according to the second embodiment, the amount of correction comments (vertical and horizontal sizes) that can be displayed in the designated area 56 by the processing unit 48 is vertical and horizontal on the paper 7 that matches the designated area 56. Is converted into the number of squares 13 and the value is displayed in the pop-up window 58 (see FIG. 11), so if the corrector enters characters on the sheet 7 within the range of the number of squares 13, An image of a handwritten character can be reproduced and displayed in the designated area 56 without reducing the handwritten character of the correction comment entered with the electronic pen 6. When the corrector fills in the sheet 7 to the extent that exceeds the number of either the vertical or horizontal direction of the grid 13, the processing means 48 reduces the stroke data of the handwritten character, reproduces the image, and designates the designated area 56. Can be inserted and displayed. Further, when the processing means 48 recognizes that the reduction ratio of the stroke data exceeds the predetermined value, the processing means 48 displays in the pop-up window 61 that the amount of correction comments to be inserted is too large. It is possible to optimize the designated area 56 by the drag operation of the mouse 42, to optimize the amount of the correction comment and the entry range, and to prevent the correction comment from being difficult to read due to excessive reduction.

  Further, according to the correction support system 1 of the second embodiment, as with the operation and effect of the correction support system 1 of the first embodiment described above, the communication correction company does not supply any device to the student. In both cases, the system can be configured by the scanner 2 and the center server 3 of the communication correction operator, the terminal device 4, the electronic pen 6 and the paper 7 of the correction operator, and the initial investment can be light. Conventionally, the time required for the communication correction company to mail the answer sheet 9 of the student directly to the corrector and return it after the correction is converted into the electronic data of the answer sheet 9, the conversion comment electronic data, It can be greatly shortened by electronic data transmission.

<Other embodiments>
The present invention is not limited to the first and second embodiments.

  For example, in the above embodiment, the processing unit 48 recognizes the end of a group of correction comments based on the double tap entry information of the electronic pen 6. Instead, a tap area for allowing the terminal device 4 to recognize the end of a batch of correction comments is provided on the form 7, and the processing means 48 transmits the entry information transmitted by tapping the tap area. Based on the above, the end of input of the correction comment may be recognized. Alternatively, an area for transmitting the entry information of the electronic pen 6 is provided on the paper 7 and the entry information is stored in the memory 609 of the electronic pen 6 until the area is tapped or marked by the electronic pen 6. In addition, when the area is tapped or marked, the entry information stored in the memory 609 is transmitted from the electronic pen 6 to the terminal device 4 so that the entry information received by the terminal device 4 is collected. You may make it recognize as a correction comment. Alternatively, when the batch of correction comments with the electronic pen 6 is completed, the terminal of the corrector is operated by operating the terminal device 4, for example, clicking the correction comment input end button set on the screen. The apparatus 4 may be configured to recognize the end of input of the correction comment.

  Further, in the above embodiment, while the end of the batch correction comment input is not recognized (step S104: No, S204: No), the processing means 48 sequentially enters the entry information from the entry information received from the electronic pen 6. From the character recognition to the warning display of over-number of characters displayed in the designated area (steps S105 to S107), or from the calculation of the circumscribed rectangle of the entire stroke to the warning display of the over-reduction rate of the stroke displayed in the designated area (steps S205 to S209) A series of processes were performed. Thus, since it calculates for every stroke, a warning display can be performed at the moment when the number of characters exceeds. Instead of this, the aggregation processing means 48 may perform a series of processes of steps S105 to S107 or steps S205 to S209 after recognizing the end of the correction comment (step S104: Yes, S204: Yes). . In this way, the processing load of the processing means 48 can be reduced by collectively calculating the strokes of a group of correction comments.

  In the above embodiment, the corrector paper 7 on which the question pattern 12, the mesh 13, and the dot pattern 11 that can be recognized by the electronic pen 1 are used is used, but the processing means 48 is handwritten by the electronic pen 1. Since it has a function of inserting characters into the designated area 56, it is also possible to use the corrector paper 7 on which the question sentence 12 or the cell 13 is not printed. At this time, when using the corrector paper 7 on which the grid 13 is not printed, the processing means 48 determines the number of vertical and horizontal characters or the total number of characters that can be entered in the designated area 56 based on the size of the easy-to-see characters. Calculate. The position and size of the correction comment inserted in the designated area 56 can be finely adjusted by dragging the mouse with the mouse by the processing of the processing unit 48.

  In the above embodiment, the processing unit 48 displays the number of cells that can be entered in the designated area 56 (steps S103 and S203), the number of characters over (step S107), and the reduction rate over (step S208) on the display unit 47. However, in addition to this, or instead of this, it may be notified by voice.

  In the above embodiment, the image data with the correction comment is printed and returned to the student by mail or the like. However, only the correction symbol and the correction comment are printed on the answer sheet 9 and returned to the student. Alternatively, the image data itself may be transmitted to the terminal device owned by the student via the Internet 8.

  Further, in the above embodiment, the data communication between the center server 3 and the terminal device 4 is performed via the Internet 8, but if the place where the corrector performs correction is near the center server 3, The data communication may be performed directly or via a small network such as a LAN. In the above embodiment, the entry information is information in which the time information, the dot pattern address, the XY coordinate data, the writing pressure data, and the pen ID are associated, but the entry information is the time information and the XY. The processing load may be reduced by using only necessary information for processing, such as coordinate data.
