FIG. 5 is a diagram for explaining the relationship between the dots of the dot pattern printed on the answer sheet 5 and the color pallet sheet 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.

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. FIG. 7 is a schematic view showing the structure of the electronic pen 1. 7, 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, a battery 112, and a terminal 113 are provided. 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 color palette paper 7 or abuts the answer paper 5 to stroke ( Write handwritten strokes). 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 measures the pressure applied through the ink cartridge 104 from the pen tip portion 103 when the student writes characters or marks on the answer sheet 5 with the electronic pen 1 or taps on the color palette sheet 7, that is, the writing pressure. The value is detected and the value 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 the student writes characters or the like on the answer sheet 5 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 5, 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 electronic pen housing unit 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 5 and the color pallet sheet 7. The area is slightly shifted from the position where the pen tip 103 contacts the answer sheet 5 and the color pallet sheet 7. 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 5, the printed ink does not have an absorptivity in the infrared region, and thus 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. 6A, 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.

  The processor 108 uses the dot pattern of the image data supplied by the CMOS camera 106 while the student's entry is performed, and the X and Y coordinates (hereinafter simply referred to as “X” and “Y” coordinates on the answer sheet 5 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. 6A supplied by the CMOS camera 106 into the data array shown in FIG. 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”. The 6 × 6 dot pattern in the answer sheet 5 and the color pallet sheet 7 does not overlap in the answer sheet 5 and the color pallet sheet 7, so when the student enters characters or the like with the electronic pen 1, Which position on the answer sheet 5 and the color pallet sheet 7 the entered position corresponds to can be specified by coordinate calculation by the processor 108.

  The memory 109 stores property information such as pen IDs “pen01” to “pen04”, pen manufacturer numbers, and pen software versions for identifying the electronic pens 1A to 1D. Then, the communication unit 111 associates the pen ID, time information (time stamp), writing pressure data, and X and Y coordinate data, and transmits them to the electronic pen housing unit 3 as entry information. Transmission to the electronic pen housing unit 3 by the communication unit 111 is immediately and sequentially performed by wireless transmission such as Bluetooth (registered trademark). Here, one or more pieces of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the electronic pen housing unit 3 are transferred to the computer device 2 by the electronic pen housing unit 3. Thereafter, it is stored as stroke information by the computer device 2. In other words, one stroke is made up of one or a plurality of X, Y coordinates (coordinate points), and the computer apparatus 2 can use one or a plurality of pieces constituting one stroke based on the pen-down information and the pen-up information. Recognize coordinate attribute information.

  The terminal 113 includes a plurality of small terminals, and is electrically connected to the terminal 313 of the electronic pen housing unit 3 by inserting the electronic pen 1 into the housing hole 31 of the electronic pen housing unit 3 illustrated in FIG. Connecting. Then, the electronic pen 1 transmits the pen ID to the processor 34 of the electronic pen housing unit 3 illustrated in FIG. 8 via a specific small terminal. Further, the electronic pen 1 is supplied with electric power from the electronic pen housing unit 3 through the other small terminals of the terminal 113 and charges the battery 112.

  Thus, each time the student fills in the answer sheet 5 and the color pallet sheet 7, the electronic pens 1 </ b> A to 1 </ b> D generate entry information and transmit it to the electronic pen housing unit 3. In other words, the electronic pens 1 </ b> A to 1 </ b> D continue to generate entry information and transmit it to the electronic pen accommodation unit 3 while the student continues to fill in the answer sheet 5 and the color palette sheet 7. When the student leaves the electronic pen 1 from the answer sheet 5 and the color pallet sheet 7 (pens up), the electronic pen 1 is no longer detected by the pressure sensor 107 to have a writing pressure higher than a predetermined value. It is determined that the student has stopped entry. 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 electronic pen housing unit 3.

[Electronic pen housing unit]

[Selected user display function]
Next, the selected user display function when the selected user display button 53 is selected will be described with reference to FIG.

  FIG. 16 shows an example of the selected user display of the drawing application window displayed when the selected user display button 53 is selected. As shown in FIG. 16, when the selected user display button 53 is selected, the processing means 24 displays the student selected by the operator using the user selection list 69 in the user stroke information display area 50 (FIG. 16). In the example shown in FIG. 16, the enlarged image 200A (200) displaying the user stroke information of “Taro”) is displayed, and other students who are not selected by the operator (in the example shown in FIG. 16, “Jiro”, “ The user stroke information of “Saburo” and “Shiro”) is displayed as a list with thumbnails 201B to 201D (201) displayed smaller than the enlarged image 200. Specifically, the processing unit 24 displays the enlarged image 200 in the upper area of the user stroke information display area 50 and displays the thumbnails 201 in a list simultaneously in the lower area of the user stroke information display area 50. In this case, the processing means 24 displays the thumbnail 201 corresponding to the user stroke information of each student at the same scale.

  More specifically, the processing means 24 uses the color palette paper 7 to select the color / line width selected by the student, or the default color / line width if no color / line width is selected. The strokes written on the answer sheet 5 by the electronic pen 1 are displayed by the student. Further, the processing unit 24 cuts out a range that includes at least the strokes entered by each student, and displays an image corresponding to the cut-out range as an enlarged image 200 and a thumbnail 201. Since the number of strokes, the stroke length, and the like are different for each student, the size of the cut-out range is different, and therefore the size of the thumbnail 201 tends to be different for each student. Further, the processing unit 24 highlights a portion of the user selection list 69 corresponding to the student selected by the operator (that is, the student displaying a large stroke). Specifically, the processing means 24 displays the number of the user selection list 69 corresponding to the student selected by the operator (“Taro” in the example shown in FIG. 16) surrounded by a frame 99 such as red. . If the thumbnails 201 to be displayed in a list do not fit in the user stroke information display area 50, the processing unit 24 enables the horizontal scroll bar 51 and scrolls the user stroke information display area 50 by the mouse operation of the operator. The thumbnail 201 can be displayed in a plurality of times.

  Note that the enlarged image 200 does not use the word “enlarge” in the sense that it is an image obtained by actually enlarging the stroke entered by the student, but it means “enlarged” in the sense that the image is larger than the thumbnail 201. Is used (the same shall apply hereinafter). This definition is similarly applied to “enlarged display” and “reduced display” described later. That is, “enlarged display” is not used to mean that the actual stroke is enlarged and displayed, but is used to mean that the actual stroke is displayed in a larger size than the thumbnail 201, and “reduced display” is used to reduce the actual stroke. It is not used in the sense of displaying the image, but is used in the meaning of displaying in a size smaller than the enlarged image 200 (the same applies hereinafter).

  On the other hand, when any one of the thumbnails 201 is selected by an operator's mouse operation or the like, the processing unit 24 displays the enlarged image 200 that has already been enlarged and reduces the selected thumbnail 201. Display. That is, the processing unit 24 displays the enlarged images 200 that have already been enlarged and displayed as a list of thumbnails 201 and displays the thumbnails 201 selected by the operator as the enlarged image 200. In other words, the enlarged image 200 that has already been enlarged and the thumbnail 201 selected by the operator are exchanged.

  In addition, as shown in FIG. 16, the currently set stroke color and line width are displayed in the color / width display field 693 of each student. Specifically, the student “Taro” displays a line segment indicating that the color is blue and the line width is 1 mm, and the student “Jiro” has a red color and the line width is 0.7 mm. A line segment indicating that the student “Saburo” has a blue color and a line width of 0.7 mm is displayed, and the student “Shiro” has a black color and a line width A line segment indicating that is 0.7 mm is displayed. When the color / line width is selected by the student using the color pallet sheet 7, the processing unit 24 displays the color / line width in the color / width display column 693. On the other hand, the processing means 24 displays the default color / line width in the color / width display field 693 when the color / line width is not selected by the student. For example, the default color is black and the default line width is 0.7 mm.

  Further, as shown in FIG. 16, the color is displayed in the user color (classification) information display field 691 of each student. Specifically, the student “Taro” is yellow, the student “Jiro” is yellow, the student “Saburo” is blue, and the student “Shiro” is red. . The operator categorizes the way of thinking (how to solve) the student's answer, assigns a color to each, and selects a desired button among the color classification buttons 71 to 76 for each student. Then, the processing means 24 displays the user color (classification) information display field 691 of each student in the color designated by the operator. In the example shown in FIG. 16, the operator assigns yellow to the idea of an answer using a sequence of numbers, assigns blue to the idea of an answer using a triangular area, and assigns red to the idea of an answer based on the trapezoid area. ing.

[Compare list display function]
Next, a comparison list display function when the comparison list display button 54 is selected will be described with reference to FIG.

  FIG. 17 shows an example of the comparison list display of the drawing application window displayed when the comparison list display button 54 is selected. As shown in FIG. 17, when the comparison list display button 54 is selected by the operator, the processing means 24 displays thumbnails 202A to 202D in which the user stroke information of each student is reduced and displayed in the user stroke information display area 50. (202) are displayed side by side at the same time. In this case, the processing means 24 displays the thumbnail 202 corresponding to the user stroke information of each student at the same scale. Further, the processing unit 24 cuts out a range including at least a stroke written by each student, and displays an image corresponding to the cut-out range as the thumbnail 202.

  Also in the example shown in FIG. 17, as in FIG. 16, colors are displayed in the user color (classification) information display field 691 of each student, and in the color / width display field 693 of each student, The currently set stroke color and line width are displayed.

[Processing flow]
Next, a processing flow performed by the electronic pen housing unit 3 and the computer device 2 in the present embodiment will be described with reference to FIGS.

(1) Processing in Electronic Pen Housing Unit FIG. 18 is a flowchart showing a procedure of processing executed by the electronic pen housing unit 3.

  First, when the electronic pen 1 is accommodated in an arbitrary accommodation hole 31 of the electronic pen accommodation unit 3, the processor 34 of the electronic pen accommodation unit 3 energizes the terminal 113 and the terminal 313 of the electronic pen 1 to energize the electronic pen 1. Is detected in the receiving hole 31 (step S101). Then, the processor 34 reads the pen ID of the electronic pen 1 through the terminal 113 of the electronic pen 1 accommodated in the accommodation hole 31 (step S102).

  Next, the processor 34 of the electronic pen accommodation unit 3 determines whether or not the electronic pen 1 is accommodated in all the accommodation holes 31A to 31D (step S103). If the electronic pen 1 is not accommodated in all the accommodation holes 31A to 31D (step S103; No), the processor 34 returns the process to step S101 again without assigning the pen ID to the user ID. The reason for this is that when the user of the electronic pen 1 accommodates the electronic pen 1 in the wrong accommodation hole 31, that is, the electronic pen that the user uses at a position different from the accommodation hole 31 specified by the name plate 32. When 1 is accommodated, one pen ID is registered in duplicate with a plurality of user IDs, or the pen ID of the electronic pen 1 to be accommodated in the electronic pen accommodation unit 3 does not correspond to any user ID. This is to prevent this from happening.

  On the other hand, when the electronic pen 1 is accommodated in all the accommodation holes 31 </ b> A to 31 </ b> D (step S <b> 103; Yes), the processor 34 corresponds to the accommodation position in the accommodation hole 31 of each electronic pen 1 accommodated in the accommodation hole 31. Then, each pen ID is associated with the user ID (step S104). Since the user ID is assigned to each accommodation hole 31, the processor 34 associates the read pen ID with the user ID corresponding to each accommodation hole 31, and displays correspondence information Iup corresponding to FIG. 10B. Generate. Then, the processor 34 transmits correspondence information Iup, which is data in which the pen ID and the user ID are associated with each other, to the computer apparatus 2 (step S105). Preferably, when the computer apparatus 2 receives the correspondence information Iup and sets the user-defined information corresponding to FIG. 12C, the “computer ID and pen ID” are displayed by voice or / and a display screen. May output such that the association between the pen ID and the user ID is reflected.

(2) Processing in Computer Device FIG. 19 is a flowchart executed to set and display a color / line width and to draw a stroke with the set color / line width. First, in the computer apparatus 2, the communication unit 23 receives the entry information received by the communication unit 35 of the electronic pen housing unit 3, and the processing unit 24 stores the entry information including the stroke information and the pen ID in the storage unit 25. (Step S201). Then, the processing unit 24 recognizes the pen ID included in the entry information (step S202). At this time, the processing unit 24 specifies the user ID and the user name corresponding to the pen ID included in the entry information by referring to the user definition information (see FIG. 12C). Next, the processing means 24 determines the type of paper from the position coordinates included in the entry information (step S203).

  In step S203, when the processing unit 24 determines that the color pallet paper 7 is filled in from the user area and paper type specified based on the position information included in the stroke information (step S203: color pallet paper), With reference to the color palette definition information (see FIG. 13), the color / line width corresponding to the user area is specified, and the stroke of the specified color / line width is determined by the electronic pen 1 of the pen ID recognized in step S202. The color / line width for drawing is set (step S204). Then, the processing means 24 displays the color / line width set in this way in the color / width display field 693 corresponding to the pen ID recognized in step S202 (step S205).

  On the other hand, when the processing unit 24 determines in step S203 that the answer sheet 5 is filled in based on the user area and the sheet type specified based on the position information included in the user stroke information (step S203: answer sheet). The stroke is drawn in the user stroke information display area 50 with the color / line width set in step S204 (step S206).

  Note that the processing means 24 sets the color and line width selected by the student when both the color and line width are selected by the student using the color palette sheet 7.

Specifically, the processor 34 determines the read pen ID (see step S102) without determining whether or not the electronic pen 1 has been accommodated in all the accommodation holes 31 (see step S103 in FIG. 18). You may transmit to the computer apparatus 2 with the user ID corresponding to the accommodation hole 31 in which the electronic pen 1 of the said pen ID was accommodated.

  In this case, when the computer apparatus 2 receives a set of user IDs and pen IDs and then determines that it has received a set of user IDs and pen IDs corresponding to all user IDs, the received user ID and pen ID The user-defined information is generated or changed based on the set.

  In the second modification, taking into account that the electronic pen 1 is taken out from the housing hole 31, the electronic pen housing unit 3 may, for example, receive the pen ID and the ID for each predetermined time width while housing the electronic pen 1. A set of user IDs may be transmitted to the computer apparatus 2. In this case, when the computer apparatus 2 receives a set of user IDs and pen IDs corresponding to all the accommodation holes 31 of the electronic pen accommodation unit 3 within the above-described predetermined time width, It may be determined that the electronic pen 1 is accommodated, and the user-defined information may be added or changed.

(Modification 3)
Instead of inputting the user name by the input means 21 of the computer apparatus 2, the computer apparatus 2 associates the pen ID of each electronic pen 1 to be used with the user name using the electronic pen 1 in the storage means 25 in advance. You may remember. In this case, in the initial state, the computer device 2 stores a table corresponding to FIG. 12B in the storage unit 25 in advance, and when the correspondence information Iup is received from the electronic pen housing unit 3, FIG. ) Corresponding to the user ID, the user name, and the pen ID are generated.

  According to this aspect, the electronic pen system 10 generates user-defined information when the user accommodates each electronic pen 1 in each accommodation hole 31 without causing the user name to be input using a keyboard or the like. Various displays can be performed.

  In addition, when there is a possibility that a plurality of users use one electronic pen 1, for example, when the electronic pen housing unit 3 and the electronic pen 1 are prepared for each classroom that moves according to a timetable, or a plurality of one in a classroom. When the electronic pen housing unit 3 and the electronic pen are prepared for each team, and the team members of each team share and use the electronic pen 1 in the team, the first embodiment is used. As described above, the computer device 2 may cause the user to input a user name corresponding to the user ID using a keyboard or the like. In this case, since the computer apparatus 2 stores the user name in association with the user ID, it can appropriately display the drawing application. Even when the electronic pen 1 malfunctions during use of the electronic pen 1 and is replaced with another electronic pen 1, in the case of the first embodiment, the user name is associated with the user ID. Therefore, the user does not need to input the user name again.

(Modification 4)
Instead of step S103 in FIG. 18, the electronic pen housing unit 3 determines whether or not the number of electronic pens 1 is greater than or equal to a predetermined number. If the number is greater than or equal to the predetermined number, step S104 and step S105 are performed. Processing may be executed.

Nmax ") may be specified by the user using the input means.

  By doing in this way, the user can flexibly use the electronic pen accommodation unit 3 even when the number of electronic pens 1 to be used is smaller than the maximum association start accommodation number Nmax. For example, the electronic pen housing unit 3 is provided for each classroom, the class using the classroom is switched, and the number of students is different for each class.

  When the association start accommodation number N smaller than the maximum association start accommodation number Nmax is set, it is desirable that the electronic pen 1 is accommodated in order from the accommodation hole 31 corresponding to the small user ID. On the other hand, in the electronic pen housing unit 3, the number of electronic pens 1 housed in the housing holes 31 becomes the association start housing number N even when the electronic pen 1 is not housed in ascending order of the user ID. In the case where it is detected, the processing of step S104 and step S105 is performed. In this case, the electronic pen unit 3 may output a warning that the electronic pen 1 is accommodated in order from the accommodation hole 31 corresponding to the small user ID by voice or display.

  Here, a supplementary description will be given of a case where Modification 2 and Modification 4 are combined. When the computer apparatus 2 makes the determination in step S103 of FIG. 18 as in the second modification, the user may be able to specify the association start accommodation number N by the input means 21 of the computer apparatus 2. Even in this case, when the computer device 2 determines that the electronic pen 1 is accommodated in the accommodation hole 31 by the association start accommodation number N, the computer device 2 generates user definition information based on the received combination of the user ID and the pen ID. Or change.

  Instead of the above description in the fourth modification, when the number of electronic pens 1 accommodated in the electronic pen accommodation unit 3 is less than the maximum association start accommodation number Nmax, the electronic pen accommodation unit 3 is not used. The electronic pen 1 having the dummy pen ID or the electronic pen 1 that is not used may be accommodated in the 31.
