FIG. 5 is a diagram for explaining the relationship between the dots of the dot pattern printed on the sheets 5 to 7 and the values to which the dots are converted. As shown in FIG. 5, 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. 6 shows an arrangement of a certain dot pattern. As shown in FIG. 6A, 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 where 6 × 6 dots are taken from any part of the paper. Yes. The dot pattern formed by these 36 dots holds position coordinates and a dot pattern address (coded pattern address). FIG. 6B is a diagram in which each dot shown in FIG. 6A is converted into a corresponding value based on the regularity shown in FIG. 5 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.

[Electronic pen]
Next, the electronic pen 1 will be described with reference to FIG. As shown in FIG. 7, the electronic pen 1 has a communication unit including a processor 108 configured by a CPU, a memory 109 such as a ROM and a RAM, an antenna, a transmission circuit, and the like inside a housing 101. 111, a battery 112, an LED 105, a CMOS camera 106, a real-time clock 110, a pressure sensor 107, and an ink cartridge 104. The tip of the ink cartridge 104 is a pen tip portion 103, and each student taps the pen tip portion 103 of the electronic pen 1 on the name list paper 6 or the color pallet paper 7 or comes into contact with the answer paper 5. You can enter your affiliation (class), name, and answers to questions.

  The battery 112 is for supplying power to each component in the electronic pen 1. For example, the attachment / detachment of the cap containing the magnet is detected by a magnetic sensor (not shown), and the electronic pen 1 itself is turned on / off. 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 characters or the like on the answer sheet 5 with the electronic pen 1, that is, the writing pressure, and sends the value to the processor 108. send.

  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 the student taps on the name list paper 6 or the color pallet paper 7 with the electronic pen 1 or writes characters on the answer paper 5, writing pressure is applied to the pen tip 103, and the pressure sensor 107 is applied. When the writing pressure of a predetermined value or more is detected, the processor 108 determines that the student has started the entry, and activates the LED 105 and the CMOS camera 106.

  The LED 105 and the CMOS camera 106 are attached in the vicinity of the pen tip portion 103 of the electronic pen 1. An opening 102 is formed in a portion of the housing 101 facing the LED 105 and the CMOS camera 106. The LED 105 irradiates infrared rays toward the vicinity of the pen tip portion 103 on the paper. The region is slightly shifted from the position where the pen tip portion 103 contacts the answer sheet 5. The CMOS camera 106 captures a dot pattern in the area illuminated by the LED 105 and supplies image data of the dot pattern to the processor 108. An imaging region by the CMOS camera 106 is a range including a size of about 2 mm × about 2 mm as shown in FIG. Imaging by the CMOS camera 106 is performed about 50 to 100 times per second.

  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 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 106 with a threshold value, it is possible to distinguish the dot area containing carbon from the other area by the difference in the amount of reflected infrared light. The ink on which the frame lines, characters, and the like of the sheets 5 to 7 are printed does not have absorbability in the infrared region, so that the dot pattern can be easily recognized.

  While the student is writing, the processor 108 calculates the XY coordinates (position coordinates) on the paper 5 to 7 of the stroke (handwriting) to be filled by the student from the dot pattern of the image data supplied by the CMOS camera 106. Calculate continuously. That is, the processor 108 converts the dot pattern image data supplied by the CMOS camera 106 into a data array as shown in FIG. 6B, and further converts it into an X coordinate bit value and a Y coordinate bit value. The XY coordinate data and the dot pattern address are calculated from the data array by a predetermined calculation method. The processor 108 then sends the current time (time stamp: entered time information) transmitted from the real-time clock 110, writing pressure data, dot pattern address, XY coordinate data, and pen ID (electronic pen identification information). Associate. Since the 6 × 6 dot patterns on the sheets 5 to 7 do not overlap in the sheets, when the student enters the answer contents with the electronic pen 1, which position on the sheet corresponds to the written position. Can be specified by coordinate calculation by the processor 108.

  The memory 109 stores a pen ID for identifying the electronic pen 1. The pen IDs “pen01” to “pen05” are stored in the respective memories 109 for the electronic pens 1A to 1E (see FIG. 1).

  The communication unit 111 sends time information (time stamp), writing pressure data, dot pattern address, XY coordinate data, and pen information associated with the pen ID directly to the aggregation device 2 or the transfer device 3. To send via. Transmission by the communication unit 111 is immediately and sequentially performed to the aggregation device 2 by a wireless transmission method of Bluetooth (registered trademark).

  Each electronic pen 1 generates entry information and transmits it to the aggregation device 2 every time a student fills in forms 5 to 7. For example, when the student touches the answer sheet 5 with the pen tip portion 103 of the electronic pen 1 (pen down) and fills in, the electronic pen 1 detects that the pressure sensor 107 detects a writing pressure of a predetermined value or more. The contact with the answer sheet 5 is detected. Then, while irradiating infrared rays with the LED 105, the dot pattern near the pen tip portion 103 is photographed with the CMOS camera 106. The processor 108 calculates the XY coordinate data and the dot pattern address at the contact position on the answer sheet 5 from the image data of the captured dot pattern. The processor 108 generates entry information in which the time information indicating the current time transmitted by the real-time clock 110, the dot pattern address, the XY coordinate data, the pen pressure data, and the pen ID are associated with each other. The data is transmitted to the aggregation device 2.

  In this way, the electronic pen 1 continues to generate entry information and send it to the aggregation device 2 while the student continues to fill in the answer sheet 5. When the student removes the electronic pen 1 from the answer sheet 5 (pen up), the electronic pen 1 stops the entry because the pressure sensor 107 no longer detects a writing pressure exceeding a predetermined value. It is determined that Then, the LED 105 and the CMOS camera 106 are stopped, and transmission of entry information to the aggregation device 2 is stopped.

The transmission means 27 is a means for transmitting the display signal to the display means 26 to the projector 4 in synchronism with the projector 4 so that the same contents as the contents displayed on the display means 26 are displayed on the projector 4.

  The storage unit 25 is configured by a memory such as a ROM, a RAM, or a hard disk, and stores each user area and position coordinates in the sheets 5 to 7 in association with each other. That is, as illustrated in FIG. 9, the storage unit 25 stores user area definition information that associates an area type and a range of position coordinates for each of the user areas 501, 601 to 606, and 701 to 706. The range of the user area is, for example, “(xn, yn), Hn, Wn”, the range from the coordinates (xn, yn) to the height (Y) direction Hn and the horizontal (X) direction Wn on each sheet 5-7. It is prescribed by. For example, the range of the user area 601 is “(x1, y1), H1, W1”, and the paper type is stored as “name list paper”.

  In addition, the storage unit 25 associates the user areas 601 to 606 on the name list sheet 6 with the user ID and stores them as name list definition information. That is, as shown to Fig.10 (a), the memory | storage means 25 has linked | related and memorize | stored user ID, a user name, and name list No. for every user area 601-606. For example, in the user area 601, the name list No. is “1”, the user ID is “U01”, and the user name is “Taro”. Here, the user names and name numbers associated with the user areas 601 to 606 correspond to the names and numbers printed in the user areas 601 to 606 of the name list paper 6.

  Further, the storage unit 25 associates each user area 701 to 706 on the color pallet sheet 7 with the color or line width (line type) and line type ID, and stores them as color pallet definition information. That is, as illustrated in FIG. 10B, the storage unit 25 has the color or line width (line type) for displaying the stroke information (handwriting) on the display unit 26 of the aggregation device 2 for each of the user areas 701 to 706.

The line types associated with the user areas 701 to 706 correspond to the line types of characters and lines printed in the user areas 701 to 706 of the color palette 7, so the user selects the line type that the user wants to use. It becomes easy and the usability of the color palette 7 is good.

  In addition, when the aggregation processing unit 24 to be described later associates the writer ID and the line type ID with the pen ID of the electronic pen 1 based on the entry information transmitted by each electronic pen 1, the storage unit 25 stores the pen ID. Is stored as pen setting information as shown in FIG. 11. Further, when the aggregation processing unit 24 associates the writer ID for each piece of entry information received from each electronic pen 1, the storage unit 25 identifies and stores the entry information for each writer ID. In the pen setting information, the writer ID and the line type ID are not set as an initial state, and the user of the electronic pen 1 designates a specific user area of the name list paper 6 or the color pallet paper 7. Thus, the aggregation device 2 stores the writer ID and the line type ID in association with the pen ID of the electronic pen 1. Therefore, the stroke information by the electronic pen 1 that is not associated with the line type ID is set by default so as to be displayed on the display unit 26 with, for example, a “black” color and a line width of “0.3 mm”.

  The storage unit 25 stores the learning data in a file format by executing the drawing application (program) by the aggregation processing unit 24. FIG. 12 shows a schematic structure of a data file format. As shown in FIG. 12, the learning data includes file attribute information and individual learning data for each writer ID.

User color (classification) information, keyword information, and the like are included. The user stroke information includes position coordinate (XY coordinate) information calculated by the electronic pen 1, time information when written, and writing pressure information. When reading the file data, the input means 21 inputs the writer ID, the user color information, the keyword information, and the like, the aggregation processing means 24 searches for specific data, and the user stroke information is reproduced on the display means 26. Can be made.

  The aggregation processing unit 24 is a unit that aggregates and processes data from the electronic pen 1 and is configured by a processor such as a CPU that exhibits a function by executing an application program. When receiving the entry information including the position coordinates and the pen ID from the electronic pen 1, the aggregation processing unit 24 refers to the relationship between the user area and the range of the position coordinates in the user area definition information shown in FIG. When it is specified that the entry information is tapped with the electronic pen 1 in the user area on the list sheet 6, the user ID associated with the user area is specified with reference to the list definition information shown in FIG. The specified user ID is associated with the pen ID of the electronic pen 1 as the writer ID and stored in the storage unit 25 as the pen setting information shown in FIG.

  Then, when the entry information on the answer sheet 5 is received thereafter, the pen setting information stored in the storage means 25 is referred to identify the writer ID associated with the pen ID included in the entry information, In association with the stroke information about the answer sheet 5, it is stored in the user stroke information storage area for each writer ID in the storage means 25. Accordingly, since the writer ID is set in the aggregation device 2 via the pen ID in the position coordinates of the answer sheet 5, a plurality of answerers use the same electronic pen 1 (see FIG. 11B). Even when different electronic pens 1 are used by the same answerer (see FIG. 11C), the user who uses the electronic pen 1 and the entry contents are stored in association with each other. It can be stored in the means 25 and recognized.

  If the aggregation processing means 24 receives the entry information including the position coordinates etc. and the pen ID about the answer sheet 5 prior to the reception of the entry information about the name list sheet 6, the aggregation processing means 24 sets the pen ID as the writer ID. The pen ID is associated and stored in the storage unit 25, and the stroke ID for the answer sheet 5 is associated with the pen ID as the writer ID and stored in the user stroke information storage area in the storage unit 25. Later, when the user ID is specified from the position coordinates of the name sheet 6 and associated with the pen ID, the pen ID received in advance with reference to the learning data file in the storage means 25 and the same pen ID as the writer ID The stroke information about the answer sheet 5 associated with the information is stored in the user stroke information storage area in the storage means 25 by newly associating the identified user ID as the writer ID. Accordingly, even if the user forgets to tap the user area 601 to 606 of the name list sheet 6 with the electronic pen 1 and starts to fill in the answer sheet 5 first, a specific user of the name list sheet 6 later with the electronic pen 1 If the information is entered in the area, the aggregation device 2 identifies the user ID from the position coordinates of the name list sheet 6 by the processing means 24 and stores the identified user ID in association with the position coordinates of the answer sheet 5 retrospectively. The position coordinates that can be stored in the means 25 and subsequently acquired on the answer sheet 5 by the aggregation device 2 can be stored in the storage means 25 in association with the same writer ID.

  In addition, the aggregation processing unit 24 displays the entry content on the display unit 26 based on the learning data including the stroke information about the answer sheet 5 and the user name corresponding to the user ID associated as the writer ID. Display. Since the entry contents by the electronic pen 1 and the user name corresponding to the user ID are displayed on the display means 26, the user can recognize the entry person and the entry contents by the person together. Further, the aggregation processing unit 24 causes the transmission unit 27 to transmit the same signal as the display signal to the display unit 26 to the projector 4 in order to synchronize and display the same contents as the display unit 26. Hereinafter, specific functions of the aggregation processing unit 24 will be described in detail.
