  Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings.

[First Embodiment]
(System configuration of display / printing system)
FIG. 1 is a system configuration diagram of a display / printing system according to the first embodiment. As shown in FIG. 1, the display / printing system includes an electronic pen 1 (1A, 1B, 1C,...) And answer sheets (entry sheets) 2 (2A, 2B, 2C,. ), A student terminal 3 (3A, 3B, 3C,...), A lecturer terminal 4 used by a lecturer, a wireless LAN router connected between the student terminal 3 and the lecturer terminal 4, and the like Transfer device 5, electronic blackboard 6, and printer 7.

  The display / printing system once displays the handwriting entered by the student on the answer sheet 2 with the electronic pen 1 on the student terminal 3 used by the student, and then displays the data indicating the handwriting on the instructor terminal 4. To aggregate. In the display / printing system, the image of the answer sheet 2 of the student is displayed on the electronic blackboard 6, and the lecturer performs scoring and comments using the electronic pen 1D. Then, the printer 7 creates an answer sheet that includes the handwriting written by the student and the handwriting added by the instructor.

  In the example of FIG. 1, the electronic pen 1 transmits the entered information to each student terminal 3 in which the electronic pen 1 is registered in advance by Bluetooth (registered trademark). Further, the exchange of data between the student terminal 3 and the transfer device 5 is performed by a wireless communication method using TCP / IP defined by WiFi (registered trademark).

  Hereinafter, each component of the display system will be described.

(1) Answer sheet The answer sheet (entry sheet) 2 will be described with reference to FIG. As shown in FIG. 2, a set of a plurality of answer sheets 2 is prepared for each student, and dot patterns (coded patterns) in different coordinate ranges are printed on the same set of answer sheets 2. Further, squares are printed on the answer sheet 2. The dot pattern is printed with ink containing carbon that absorbs infrared rays, and the squares are printed with ink that does not absorb in the infrared region. The answer sheet 2 may be printed with an entry field, a question, an answer field, or the like instead of or in addition to the squares. Hereinafter, the data printed in advance on the answer sheet 2 and showing the diagram of the question, entry field, answer field, etc. will be referred to as “answer sheet data”.

  As for the correspondence between the electronic pen 1 and the answer sheet 2 and the student (entrant), in this embodiment, as shown in FIG. 3, the student “Taro” uses the electronic pen 1A to answer the answer sheet 2A as shown in FIG. The student “Jiro” answers the answer sheet 2B using the electronic pen 1B, and the student “Saburo” answers the answer sheet 2C using the electronic pen 1C. In addition, the instructor operates the instructor terminal 4 and corrects, comments, etc. using the electronic pen 1D on the answer of the student displayed on the electronic blackboard 6.

(2) Dot Pattern Next, an Anoto dot pattern (coded pattern) printed on the answer sheet 2 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram for explaining the relationship between the dots of the dot pattern printed on the answer sheet 2 and the values to which the dots are converted. As shown in FIG. 3, each dot of the dot pattern 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 are determined by the combination of the information thus associated.

  FIG. 4A 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 can be obtained no matter which part of the paper is taken 6 × 6 dots. Yes. The dot pattern formed by these 36 dots holds position coordinates (for example, where the dot pattern is on the answer sheet 2). 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. 4 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 1 that captures an image of a dot pattern.

(3) Electronic Pen Next, the electronic pen 1 will be described with reference to FIG. FIG. 5 is a schematic view showing the structure of the electronic pen 1. As shown in FIG. 5, the electronic pen 1 includes an ink cartridge 104, an LED 105, a CMOS camera 106, a pressure sensor 107, a processor 108 including a CPU, a memory 109 such as a ROM and a RAM, A communication unit 111 including a real-time clock 110, an antenna, and the like, and a battery 112 are provided. The tip of the ink cartridge 104 is a pen tip portion 103, and each student touches the answer tip 2 with the pen tip portion 103 of the electronic pen 1 and enters a stroke (handwritten stroke). The ink of the ink cartridge 104 does not include a material that absorbs infrared rays (for example, carbon). Here, contact of the pen tip portion 103 of the electronic pen 1 with the paper is referred to as “pen down”, and removal of the pen tip portion 103 from the contact (contact) state is referred to as “pen up”. . A trajectory written between the pen-down and pen-up of the electronic pen 1 is one stroke, and characters, figures, etc. are composed of one or a plurality of strokes.

  The battery 112 is for supplying electric power to each component in the electronic pen 1. For example, the battery 112 is configured to turn on / off the electronic pen 1 itself by attaching and detaching a cap (not shown) of the electronic pen 1. May be. The real time clock 110 transmits time information indicating the current time (time stamp) and supplies the time information to the processor 108. The pressure sensor 107 detects the pressure applied through the ink cartridge 104 from the pen tip portion 103 when the student writes or taps a letter or mark on the answer sheet 2 with the electronic pen 1, that is, the writing pressure. Is transmitted to the processor 108.

  The processor 108 switches on / off the switches of the LED 105 and the CMOS camera 106 based on the writing pressure data supplied from the pressure sensor 107. That is, when a student writes a character or the like on the answer sheet 2 with the electronic pen 1, the pen pressure is applied to the pen tip portion 103, and when the pressure sensor 107 detects a writing pressure higher than a predetermined value, the processor 108 It is determined that the student has started entry, and the LED 105 and the CMOS camera 106 are operated. When the student finishes entering one stroke and releases the electronic pen 1 from the answer sheet 2, the pressure sensor 107 detects pen-up because no writing pressure exceeding a predetermined value is detected. Then, the communication unit 111 associates the pen-up information detected by the pressure sensor 107 with the pen ID and transmits it as entry information to the student terminal 3.

  The LED 105 and the CMOS camera 106 are attached near the pen tip portion 103 of the electronic pen 1, and an opening 102 is formed in a portion of the housing 101 that faces the LED 105 and the CMOS camera 106. The LED 105 illuminates infrared rays toward the vicinity of the pen tip portion 103 on the answer sheet 2. The region is slightly shifted from the position where the pen tip portion 103 contacts the answer sheet 2. The CMOS camera 106 is provided with an infrared transmission filter that transmits infrared rays and blocks non-infrared rays. The CMOS camera 106 captures a dot pattern in an area illuminated by the LED 105, and the image data of the dot pattern is captured. This is supplied to the processor 108. Here, since carbon absorbs infrared rays, the infrared rays irradiated by the LED 105 are absorbed by the carbon contained in the dots. Therefore, the dot portion has a relatively small amount of infrared reflection, and the portion other than the dot has a relatively large amount of infrared reflection. By photographing with the CMOS camera 106, a threshold value is provided based on the difference in the amount of reflected infrared light, so that a dot region containing carbon can be distinguished from other regions. Therefore, even when an entry column or the like is printed on the answer sheet 2, the printed ink does not absorb in the infrared region, so the processor 108 can recognize the dot pattern. Note that the shooting area by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. 4A, and the shooting by the CMOS camera 106 is performed at regular intervals of about 50 to 100 times per second. Is called. Further, the CMOS camera 106 has a sufficient depth of field in order to photograph dots clearly.

  While the student's entry is performed, the processor 108 uses the dot pattern of the image data supplied by the CMOS camera 106 to determine the X and Y coordinates (hereinafter simply referred to as “X” and “Y” coordinates on the answer sheet 2 of the stroke (handwriting) to be entered by the student. (Also called “coordinate data” or “coordinate information”) is continuously calculated. That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 4 (a) supplied by the CMOS camera 106 into the data array shown in FIG. 4 (b). The data is converted into a Y coordinate bit value, and X and Y coordinate data are calculated from the data array by a predetermined calculation method. The processor 108 has a rotation correction processing function for correcting the arrangement of dots on the image due to the angle of the electronic pen 1 facing the dot pattern, and is used for coordinate calculation. Then, the processor 108 associates the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, and X and Y coordinate data. Hereinafter, these associated data are collectively referred to as “coordinate attribute information”. Since the 6 × 6 dot pattern in the answer sheet 2 does not overlap in the answer sheet 2, when the student enters characters or the like with the electronic pen 1, the entered position is any position on the answer sheet 2. Can be specified by coordinate calculation by the processor 108.

  The memory 109 stores property information such as pen IDs “pen01” to “pen03”, pen manufacturer numbers, and pen software versions for identifying the electronic pens 1A to 1C. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits it as entry information to the student terminal 3. Transmission to the student terminal 3 by the communication unit 111 is immediately and sequentially performed by wireless transmission such as Bluetooth (registered trademark). Here, one or more coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the student terminal 3 is stored as stroke information by the student terminal 3. . In other words, one stroke is composed of one or a plurality of X and Y coordinates (coordinate points), and the student terminal 3 includes one or a plurality of strokes that constitute one stroke based on pen-down information and pen-up information. Recognize pieces of coordinate attribute information.

  Moreover, each electronic pen 1A-1C is exchanging information, such as a pass key which is an authentication key, with the student terminals 3A-3C used by the user of each electronic pen 1A-1C by a pairing operation in advance. The student terminal 3 is recognized as a communication partner for Bluetooth communication. The electronic pens 1 </ b> A to 1 </ b> C generate entry information each time the student enters the answer sheet 2 and transmits the entry information to the student terminal 3. In other words, the electronic pens 1 </ b> A to 1 </ b> C continue to generate entry information and transmit it to the student terminal 3 while the student continues to fill in the answer sheet 2. Then, when the student removes the electronic pen 1 from the answer sheet 2 (pens up), the electronic pen 1 does not detect a writing pressure higher than a predetermined value by the pressure sensor 107, and the student fills in. Determined to have stopped. In this case, the pen-up electronic pen 1 stops the LED 105 and the CMOS camera 106 and stops sending the entry information to the student terminal 3. The electronic pen 1D used by the lecturer is basically configured in the same manner as the electronic pens 1A to 1C used by the student.

(4) Student terminal Next, the student terminal 3 will be described. The student terminal 3 includes, as hardware, an antenna device capable of data communication with the electronic pen 1, a processor such as a CPU, a memory such as a ROM and a RAM, a display, a touch panel, and the like. In the present embodiment, it is assumed that the student terminal 3 is a tablet terminal such as iPad (registered trademark) distributed to each student.

The student terminal 3 functionally includes an input unit 31 such as a touch panel, a communication unit 32, a storage unit 33, a processing unit 34, and a display unit 36. The communication unit 32 is configured by an antenna receiving circuit or the like, and receives entry information from the electronic pen 1 and exchanges predetermined data via the instructor terminal 4 and the transfer device 5. The display unit 36 is configured by a display or the like, and displays the contents instructed by the processing unit 34.

  The processing unit 34 is configured by a processor such as a CPU, and controls the entire student terminal 3 by executing a program stored in the storage unit 33.

  For example, the processing unit 34 performs communication control of the communication unit 32. Specifically, the processing unit 34 receives the entry information transmitted from the electronic pen 1 that has undergone the pairing operation via the communication unit 32. Further, the processing unit 34 transmits stroke information generated from the entry information received from the electronic pen 1 to the instructor terminal 4 through the communication unit 32.

  The storage unit 33 is configured by a memory such as a ROM or a RAM. The storage unit 33 stores information on the coordinate range indicated by the dot pattern printed on each page of the answer sheet 2 (also referred to as “coordinate definition information”). In addition, the storage unit 33 stores in advance the pen ID of the electronic pen 1 on which the pairing operation has been performed, the communication address of the instructor terminal 4, a program necessary for the processing unit 34 to execute predetermined processing, and the like. Yes. Further, the storage unit 33 stores the entry information received from the electronic pen 1 for each pen ID as stroke information in accordance with the processing instruction of the processing unit 34.

(5) Instructor Terminal Next, the instructor terminal 4 will be described. The instructor terminal 4 includes, as hardware, an antenna device capable of data communication with the electronic pen 1, a processor such as a CPU, a memory such as a ROM and a RAM, a display, a touch panel, and the like. The instructor terminal 4 is, for example, a notebook PC.

The instructor terminal 4 functionally includes an input unit 41 such as a mouse and a keyboard, a communication unit 42, a storage unit 43, a processing unit 44, and a display unit 46. The communication unit 42 is configured by an antenna receiving circuit or the like, and exchanges predetermined data via the student terminal 3 and the transfer device 5. The display unit 46 is configured by a display or the like, and displays the contents instructed by the processing unit 44.

  The processing unit 44 is configured by a processor such as a CPU, and controls the entire instructor terminal 4 by executing a program stored in the storage unit 43. For example, the processing unit 44 performs communication control of the communication unit 42. Specifically, the processing unit 44 receives stroke information from each student terminal 3 by the communication unit 42 and stores it in the storage unit 43. Further, the processing unit 44 causes the display unit 46 to display the handwriting that the student has entered on the answer sheet 2 based on the stroke information received from each student terminal 3.

  The storage unit 43 is configured by a memory such as a ROM or a RAM. The storage unit 43 stores coordinate definition information regarding the dot pattern printed on each page of the answer sheet 2, a program necessary for the processing unit 44 to execute a predetermined process, and the like. The storage unit 43 has a handwriting database (DB) that stores handwriting data for each answer sheet of each student. FIG. 8A shows an example of the contents stored in the handwriting DB.

  As shown in FIG. 8A, for each student, the handwriting DB is a student ID, a student name, an answer sheet ID, an answer sheet data, a dot pattern ID, dot pattern data, student handwriting data, an instructor. Memorize handwriting data. Here, the student ID is identification information given to each student, and the answer sheet ID is identification information of the answer sheet. The answer sheet data is data of a portion of the answer sheet diagram (answer sheet problem, answer column, etc.). Note that the answer sheet ID is identification information assigned to each answer sheet distributed to the student, and even if the same content (question or answer field) is printed, the answer sheet of another student is a dot. Since the patterns are different, another answer sheet ID is given. Even if answer sheets are distributed to the same students, answer sheets with different contents (questions and answer fields) are given different answer sheet IDs.

  The dot pattern ID is dot pattern identification information provided on the answer sheet 2, and for example, a dot pattern address is used. The dot pattern data is data of a dot pattern as illustrated in FIG. The handwriting data of the student is electronic data indicating the handwriting entered by the student on the answer sheet 2 with the electronic pen 1. The instructor's handwriting data is electronic data indicating handwriting added as a scoring, comment, etc. to the answer sheet image displayed on the electronic blackboard 6 by the instructor. The handwriting data is electronic data including the entered stroke information. In addition to the above, when an electronic pen is assigned to each student separately, a pen ID that is identification information of the electronic pen may be stored in the handwriting DB.

  The communication unit 42 and the processing unit 44 are examples of the “first transmission unit”, the “second transmission unit”, the “first reception unit”, and the “second reception unit” in the present invention. The storage unit 43 is an example of the “storage unit” in the present invention.

(6) Electronic Blackboard The electronic blackboard 6 can communicate with the instructor terminal 4 and displays information transmitted from the instructor terminal 4 on the display unit 6a. Specifically, the electronic blackboard 6 receives the answer sheet data and the student handwriting data from the instructor terminal 4 and displays them on the display unit 6a. Thereby, the answer sheet of a certain student is reproduced on the display unit 6a. The electronic blackboard 6 may include, for example, a liquid crystal display panel or the like as the display unit 6a and display data received from the instructor terminal by wire. Instead, the electronic blackboard 6 may be configured as a screen that projects an image output by a projector (not shown) connected to the instructor terminal 4. In any case, a dot pattern unique to the electronic blackboard 6 is formed on the surface of the display unit 6a.

  Since the dot pattern is formed on the display unit 6a, when the instructor fills in the display unit 6a using the electronic pen 1D, the contents of the entry are acquired by the electronic pen 1D, transmitted to the instructor terminal 4, and stored. Is done. The dot pattern formed on the display unit 6a of the electronic blackboard 6 is different from the dot pattern formed on the answer sheet 2 distributed to the students. The electronic blackboard 6 is an example of the “display device” in the present invention.

  When the electronic blackboard 6 receives the student handwriting data and answer sheet data from the instructor terminal 4, the electronic blackboard 6 displays them on the electronic blackboard 6 (step S14). As a result, the answer sheet of the student is reproduced and displayed on the electronic blackboard 6. Next, when the instructor adds scoring and comments on the electronic blackboard 6 using the electronic pen 1D, the electronic pen 1D acquires handwriting data indicating the contents entered by the instructor and transmits it to the instructor terminal 4 (step) S15).

  When the instructor's handwriting data is received from the instructor's electronic pen 1D, the instructor terminal 4 stores the instructor's handwriting data in the handwriting DB as shown in FIG. 8A (step S16). Further, when a print instruction is input by the instructor, the instructor terminal 4 sends answer sheet data, dot pattern data stored in association with the answer sheet, and student handwriting data from the handwriting DB, The instructor's handwriting data is extracted and transmitted to the printer 7 (step S17).

  The printer 7 prints the dot pattern data, answer sheet data, student handwriting data, and instructor handwriting data received from the instructor terminal 4 on the blank printing paper 2X (step S18). Thus, the printer 7 can create the answer sheet 2Y on which answer sheet data and a dot pattern are printed, and on which the student's handwriting and the instructor's handwriting are printed. The student can continue answering by filling in the answer sheet 2Y with the electronic pen 1 while watching the comments written by the lecturer.

  According to the first embodiment, the answer sheet data of the answer sheet 2 used by the student, the same dot pattern as the dot pattern formed on the answer sheet 2, the student handwriting data, By printing the handwriting data on the new printing paper 2X, it is possible to create the answer paper 2Y reflecting the handwriting such as the comment of the lecturer.

[Second Embodiment]
In the first embodiment, the answer sheet 2 reflecting the instructor's handwriting is created by printing the same dot pattern on the print sheet 2X as the answer sheet 2 used by the student. In contrast, in the second embodiment, a dot pattern (hereinafter referred to as “new dot pattern”) that is different from the answer sheet 2 used by the student is printed on the print sheet 2X. An answer sheet 2Y reflecting handwriting is created.

  The configuration of the display / printing system in the second embodiment is basically the same as that of the display / printing system in the first embodiment shown in FIG.

  FIG. 10 is a flowchart of the printing process in the second embodiment. Note that the process of the student terminal 3 shown in FIG. 10 is performed by the processing unit 34 executing the program stored in the storage unit 33. Further, the processing of the instructor terminal 4 is performed by the processing unit 44 executing a program stored in the storage unit 43.

  The processing in steps S11 to S16 in FIG. 10 is the same as the printing processing in the first embodiment shown in FIG. In step S16, after the instructor's handwriting data is stored in the handwriting DB, when the instructor's printing instruction is input, the instructor terminal 4 determines a new dot pattern, and a new dot pattern ID and dot indicating a new dot pattern. The pattern data is stored in the handwriting DB in association with the answer sheet ID as shown in FIG. The instructor terminal 4 determines a dot pattern that is not used for any other answer sheet as a new dot pattern. The instructor terminal 4 transmits the answer sheet data, the determined new dot pattern data, the student handwriting data, and the instructor handwriting data to the printer 7 (step S17a).

  The printer 7 prints the received new dot pattern data, answer sheet data, student handwriting data, and instructor handwriting data on the blank printing paper 2X (step S18a). The answer sheet 2Y created in this way reflects the handwriting of the student and the handwriting of the instructor. Further, the dot pattern formed on the answer sheet 2Y is different from the dot pattern formed on the original answer sheet 2, but as shown in FIG. 8B, new dots corresponding to the dot pattern are formed. The pattern ID is stored in the handwriting DB in association with the answer sheet ID. Therefore, items that the student has entered on the answer sheet 2Y can be stored in the handwriting DB in association with the original answer sheet 2 as additional handwriting data. That is, the handwriting data for the new answer sheet 2Y can be stored and managed together with the handwriting data for the original answer sheet 2.

  According to the second embodiment, the answer sheet data of the answer sheet 2 used by the student, a new dot pattern different from the dot pattern formed on the answer sheet 2, the student's handwriting data, and the instructor By printing the handwriting data on the new printing paper 2X, it is possible to create the answer paper 2Y reflecting the handwriting such as the comment of the lecturer.

[Third Embodiment]
In the second embodiment, the answer sheet 2 reflecting the instructor's handwriting is created by printing the new dot pattern on the blank print sheet 2X. On the other hand, in the third embodiment, the answer sheet 2 reflecting the instructor's handwriting is created by using the print sheet 2Z on which a new dot pattern is already printed.

  The configuration of the display / printing system in the third embodiment is basically the same as that of the display / printing system in the first embodiment shown in FIG. However, in the third embodiment, in FIG. 1, the printing paper 2Z on which the dot pattern has already been printed is used instead of the blank printing paper 2X.

  FIG. 11 is a flowchart of print processing in the third embodiment. Note that the processing of the student terminal 3 shown in FIG. 11 is performed by the processing unit 34 executing a program stored in the storage unit 33. Further, the processing of the instructor terminal 4 is performed by the processing unit 44 executing a program stored in the storage unit 43.

  The processing in steps S11 to S16 in FIG. 11 is the same as the printing processing in the first embodiment shown in FIG. In step S16, after the instructor's handwriting data is stored in the handwriting DB, when the instructor print instruction is input, the instructor terminal 4 receives the answer sheet data, the student's handwriting data, and the instructor's handwriting data. The data is transmitted to the printer 7 (step S17b).

  The printer 7 is loaded with printing paper 2Z on which a new dot pattern has already been printed. Then, the printer 7 prints the answer sheet data received from the instructor terminal 4, the student handwriting data, and the instructor handwriting data on the printing sheet 2Z (step S18b). The answer sheet 2Y created in this way reflects the handwriting of the student and the handwriting of the instructor. However, the new dot pattern formed on the answer sheet 2Y is different from the dot pattern formed on the original answer sheet 2. Accordingly, the student enters his / her own electronic pen 1 on the output answer sheet 2Y. The student's electronic pen 1 acquires a new dot pattern ID from the answer sheet 2Y and transmits it to the instructor terminal 4 via the student terminal 3, the transfer device 5, and the like (step S19).

  As shown in FIG. 8B, the instructor terminal 4 stores the received new dot pattern ID in association with the answer sheet ID in the handwriting DB. New dot pattern data is also stored in the handwriting DB as necessary. Thus, the newly created answer sheet 2Y is associated with the original answer sheet 2. As a result, the items that the student subsequently enters on the answer sheet 2Y are stored in the handwriting DB in association with the answer sheet 2 as additional handwriting data. That is, the handwriting data for the new answer sheet 2Y can be stored and managed together with the handwriting data for the original answer sheet 2.

  According to the third embodiment, the answer sheet data of the answer sheet 2 used by the student, the handwriting data of the student, and the handwriting data of the instructor are printed on the print sheet 2Z on which the new dot pattern is formed. By printing, it is possible to create an answer sheet 2Y that reflects handwriting such as the comment of the lecturer.

[Fourth Embodiment]
In the first to third embodiments, the answer sheet reflecting the instructor's handwriting is printed by printing the student's handwriting data and the instructor's handwriting data on a printing sheet 2X or 2Z different from the original answer sheet 2 2Y is created. In contrast, in the fourth embodiment, the handwriting of the instructor is printed on the original answer sheet 2 itself used by the student.

  FIG. 12 shows the configuration of a display / printing system in the fourth embodiment. The configuration of the display / printing system in the fourth embodiment is basically the same as that of the display / printing system in the first embodiment shown in FIG. However, the printer 7a includes a reading device such as an optical reader or a camera for reading the dot pattern of the answer sheet 2 set therein. Alternatively, when the answer sheet ID is printed in the form of a barcode or the like on the answer sheet 2, the printer 7a includes a reading device such as a barcode reader for reading the barcode. As shown in FIG. 12, the fourth embodiment is different from FIG. 1 in that the paper set in the printer 7a is the answer paper 2 used by the student.

  FIG. 13 is a flowchart of the printing process in the fourth embodiment. The process of the student terminal 3 shown in FIG. 13 is performed by the processing unit 34 executing the program stored in the storage unit 33. Further, the processing of the instructor terminal 4 is performed by the processing unit 44 executing a program stored in the storage unit 43.

  The processing in steps S11 to S16 in FIG. 13 is the same as the printing processing in the first embodiment shown in FIG. After the instructor's handwriting data is stored in the handwriting DB in step S16, the instructor or the student sets the answer sheet 2 used by the student in the printer 7a. When the instructor print instruction is input, the printer 7a reads the dot pattern or barcode of the set answer sheet 2 by the reading device to obtain the dot pattern ID or answer sheet ID, which is used for the instructor. It transmits to the terminal 4 (step S17c). The instructor terminal 4 refers to the handwriting DB and transmits the instructor's handwriting data corresponding to the received dot pattern ID or answer sheet ID to the printer 7a (step S18c). The printer 7a prints the instructor's handwriting data received from the instructor terminal 4 on the printing paper 2 (step S19c).

  The answer sheet 2 output in this way is the answer sheet that was originally used by the student, on which handwriting such as an instructor's comment has been printed. Therefore, the items that the student subsequently enters on the answer sheet 2 are stored in the handwriting DB as additional handwriting data in association with the answer sheet. In the fourth embodiment, the printer 7a reads the dot pattern ID or the answer sheet ID from the set answer sheet and prints the corresponding instructor's handwriting data. Therefore, the instructor's handwriting data is stored in the handwriting DB. After that, no matter what timing the answer sheet 2 is set in the printer 7a and a print instruction is given, the handwriting data of the corresponding instructor can be printed on the answer sheet.

[Modification]
In the configuration example shown in FIGS. 1 and 12, handwriting data acquired by the student's electronic pen 1 is transmitted to the instructor terminal 4 via the student terminal 3. Instead, the handwriting data acquired by the student's electronic pen 1 may be transmitted to the instructor terminal 4 through a receiver or the like without using the student terminal.

  In the above embodiment, the instructor performs additional writing on the electronic blackboard 6 with the electronic pen 1D, but instead, other students may perform additional writing. In the above embodiment, since the answer sheet is provided with a question and answer column, the answer sheet data is transmitted to the printers 7 and 7a and printed together with the handwriting data. When a plain answer sheet that is not printed is used, the answer sheet data does not exist and is not printed by the printers 7 and 7a.

  In the above-described embodiment, the Anoto method is used for the electronic pen, the dot pattern (coded pattern), and the entry information, but the present invention is not limited to the Anoto method. Further, the dot pattern (coded pattern) is not limited to the one indicating the position coordinates, and may be a code value for identifying the icon or a code value for identifying the association area.
