<First Embodiment>
First, a first embodiment according to the present invention will be described.

[Configuration of information processing system]
FIG. 1 shows a configuration of an information processing system according to the first embodiment. As shown in FIG. 1, the information processing system includes an electronic pen 1 used by a user, a computer device 2 that receives and processes entry information from the electronic pen 1, and dot patterns having different coordinate ranges. A plurality of notebook papers 4, a heading paper 5 for separating the notebook papers 4 by subject, and a multi-hole file 6 for binding the notebook paper 4 and the heading paper 5.

  The plurality of notebook sheets 4 correspond to so-called loose leaves, and the contents corresponding to the subject (for example, contents obtained by copying a board written in a lecture) are filled in with the electronic pen 1. On the plurality of notebook papers 4, dot patterns having different coordinate ranges (in other words, unique dot patterns) are formed. The dot pattern is printed with ink containing carbon that absorbs infrared rays. Further, the plurality of notebook papers 4 are formed with holes for binding by the multi-hole file 6. In this embodiment, the dot pattern is based on the Anoto method, but other coding patterns may be used.

  The computer device 2 includes a processor such as a CPU, a memory such as a ROM and a RAM, a display, etc., and receives entry information from the electronic pen 1 and performs various processes. For example, the computer apparatus 2 is “iPad (registered trademark)”.

  Here, a usage form of the information processing system as shown in FIG. 1 will be briefly described. The computer apparatus 2 displays on the display a time schedule table in which lecture subjects (categories) are associated with days of the week and time periods. The user refers to the timetable displayed in this way, and designates one subject from the plurality of subjects displayed in the timetable. At this time, the computer apparatus 2 displays, on the display, a plurality of units and chapters for classifying the content of the subject in a tree diagram for the subject designated by the user. The user designates one chapter from the plurality of chapters displayed in the tree diagram in this way. At this time, the computer apparatus 2 opens a file used for the chapter designated by the user. The file is for storing handwritten strokes written on the notebook paper 4 by the electronic pen 1 for each chapter and storing them in the number of a plurality of chapters of each of a plurality of subjects. When the file is opened as described above, the computer device 2 displays the handwritten strokes written on a predetermined page (for example, the final page on which the handwritten strokes are written) among the handwritten strokes written about the chapter of the file. Display above. Further, the user enters a handwritten stroke on the notebook paper 4 with the electronic pen 1. At this time, the computer apparatus 2 draws the handwritten stroke on the display and stores the handwritten stroke in the file opened as described above.

[Dot pattern]
The Anoto dot pattern formed on the note paper 4 will be described with reference to FIGS. FIG. 2 is a diagram for explaining the relationship between the dots of the dot pattern formed on the notebook paper 4 and the values to which the dots are converted. As shown in FIG. 2, each dot of the dot pattern is associated with a predetermined value depending on its position. That is, 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 virtual grid (the intersection of the vertical and horizontal lines). 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 notebook paper 4 are determined by the combination of the information thus associated.

  FIG. 3A shows an arrangement of a certain dot pattern. As shown in FIG. 3A, 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 notebook paper 4 is taken 6 × 6 dots. ing. A dot pattern formed by these 36 dots holds position coordinates (for example, where the dot pattern is located on the note paper 4). FIG. 3B is a diagram in which each dot shown in FIG. 3A is converted into a value associated with the regularity shown in FIG. 2 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. 4 is a schematic diagram showing the structure of the electronic pen 1. 4, 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 the user touches the pen tip portion 103 of the electronic pen 1 to the notebook paper 4 and enters a stroke (handwritten stroke). Here, contact of the pen tip portion 103 of the electronic pen 1 with the note paper 4 is referred to as pen-down, and removal of the pen tip portion 103 from the contacted (contacted) 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. Since the ink of the ink cartridge 104 does not include a material that absorbs infrared rays, the reading of the dot pattern by the processor 103 is not hindered.

  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 user writes characters or marks on the notebook paper 4 with the electronic pen 1, that is, the writing pressure, and sends the value to the processor 108. To transmit.

  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 user writes characters or the like on the notebook paper 4 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 Is started, the LED 105 and the CMOS camera 106 are operated. Then, the communication unit 111 associates the pen-down information PD detected by the pressure sensor 107 with a pen ID described later, and transmits it to the computer apparatus 2 as entry information. When the user completes one stroke and moves the electronic pen 1 away from the notebook paper 4, 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 to the computer apparatus 2 as entry information.

  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 notebook paper 4. The area is slightly deviated from the position where the pen tip 103 contacts the notebook paper 4. 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. 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 small amount of infrared reflection, and the portion other than the dot has a 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 characters, frame lines, and the like are printed on the note paper 4, 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. 3A, 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 performs X and Y coordinates (hereinafter simply referred to as “position”) on the notebook paper 4 of the stroke (handwriting) to be entered by the user from the dot pattern of the image data supplied by the CMOS camera 106 during the user entry. The coordinates are also called “coordinates” or “coordinate information”). That is, the processor 108 converts the image data of the dot pattern as shown in FIG. 3A 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. Note that 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 this function is exhibited during the 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 on the notebook paper 4 does not overlap in the notebook paper 4, when the user enters characters or the like with the electronic pen 1, the entered position corresponds to any position on the notebook paper 4. This can be specified by coordinate calculation by the processor 108.

  The memory 109 stores property information such as a pen ID such as “pen01” for identifying the electronic pen 1, a pen manufacturer number, and a pen software version. 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 computer apparatus 2 as entry information. Transmission to the computer apparatus 2 by the communication unit 111 is performed immediately and sequentially by wireless transmission such as Bluetooth (registered trademark). Here, one or a plurality of coordinate attribute information generated between the pen-down and pen-up of the electronic pen 1 and transmitted to the computer device 2 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. As described above, a set of coordinate attribute information generated by the electronic pen 1 when the user enters one stroke is referred to as “stroke information”.

Functionally, the computer apparatus 2 includes an input unit 21, a communication unit 22, a processing unit 24, a storage unit 25, and a display unit 26.

  The input means 21 includes a mouse and a keyboard for inputting various commands and data. When the display unit 26 is a touch panel system, the touch panel provided on the display screen of the display unit 26 also functions as the input unit 21. The communication unit 22 includes an antenna receiving circuit and the like, receives entry information from the electronic pen 1, and transmits it to the processing unit 24. The communication means 22 corresponds to an example of “reception means” in the present invention. The display means 26 is constituted by a display or the like, and displays the contents instructed by the processing means 24.

  The storage means 25 is configured by a memory such as a hard disk, ROM, or RAM. The storage means 25 stores the entry information received from the electronic pen 1 for each pen ID according to the processing instruction of the processing means 24, and further secures a storage area according to the instruction of the processing means 24, from pen down to pen up. Is stored as stroke information for each pen ID. Specifically, the storage unit 25 stores, for each of a plurality of subjects, handwritten strokes written on the notebook paper 4 by the electronic pen 1 for each file corresponding to each of a plurality of chapters of the plurality of subjects. doing. Specifically, the storage unit 25 stores a file corresponding to each of a plurality of chapters included in each subject in a folder corresponding to each of the plurality of subjects.

  In addition, the storage unit 25 stores various information generated by the execution of the program according to instructions from the processing unit 24. As an example of various types of information, the storage unit 25 stores coordinate definition information indicating the coordinate range of the dot pattern assigned to each of the plurality of notebook papers 4. Further, the storage means 25 stores data of a timetable in which subjects of lectures to be performed are associated with each day of the week and each time period. In addition, for each of a plurality of subjects, the storage means 25 stores tree diagram data represented by a plurality of units, chapters, sections, etc. for classifying the contents of each subject in stages.

  The processing means 24 is constituted by a processor such as a CPU and controls the entire computer apparatus 2. Specifically, the processing unit 24 includes a determination unit 241, a storage instruction unit 242, a display control unit 243, a notification unit 244, and an acquisition unit 245.

  The acquisition unit 245 of the processing unit 24 acquires a course designated by the user from among a plurality of courses displayed on the timetable by the display control unit 243 described later. Specifically, the acquisition unit 245 identifies the subject designated by the user using the input unit 21 based on the timetable data stored in the storage unit 25. For example, the acquisition unit 245 acquires the subject specified by the user clicking with the mouse or touch-inputting with the touch panel. Thus, the acquisition unit 245 corresponds to an example of “category acquisition unit” in the present invention.

  The acquisition unit 245 acquires a chapter specified by the user from among a plurality of chapters displayed in a tree diagram by the display control unit 243 described later. Specifically, the acquisition unit 245 acquires a chapter specified by the user using the input unit 21. For example, the acquisition unit 245 acquires a chapter specified by a user clicking with a mouse or touch-inputting with a touch panel. Thus, the acquisition unit 245 corresponds to an example of the “item acquisition unit” in the present invention.

  The determination unit 241 of the processing unit 24 determines whether a file corresponding to the chapter acquired by the acquisition unit 245 is stored in the storage unit 25 when the user specifies a chapter as described above. The determination unit 241 determines whether or not the file is opened when the user enters a handwritten stroke on the notebook paper 4 with the electronic pen 1. If the file is open, the determination unit 241 determines whether the file is a new file. Further, the determination unit 241 determines whether or not the notebook paper 4 on which a handwritten stroke is written by the electronic pen 1 is a new notebook paper 4. That is, the determination unit 241 determines whether the notebook paper 4 filled with the electronic pen 1 is the notebook paper 4 on which the handwritten stroke has already been written, or the notebook paper 4 on which the handwritten stroke has not yet been written. To do. In this case, the determination unit 241 refers to the coordinate definition information stored in the storage unit 25 (specifically, coordinate definition information indicating the coordinate range of the dot pattern assigned to the plurality of notebook papers 4). The notebook paper 4 in which the handwritten stroke is written is specified, and such a determination is made based on whether or not the data of the notebook paper 4 is included in a file stored by the save instruction unit 242 described later. In addition, the determination unit 241 determines whether or not the chapter corresponding to the currently opened file matches the chapter of the subject corresponding to the note paper 4 on which the handwritten stroke is entered.

  The storage instructing unit 242 of the processing unit 24 has acquired the handwriting stroke (specifically, the handwriting stroke corresponding to the entry information received by the communication unit 22) written on the notebook paper 4 by the electronic pen 1. It is stored in the storage means 25 in a file associated with the chapter. Specifically, the save instruction unit 242 stores the handwritten stroke in a file corresponding to the chapter acquired by the acquisition unit 245 stored in the folder of the corresponding subject. Further, the save instruction unit 242 stores the handwritten stroke entered on the note paper 4 in the storage unit 25 in association with the page of the note paper 4. In this case, when it is determined by the determination means 241 that the handwriting stroke has been entered in the notebook paper 4 on which the handwriting stroke has already been entered, the storage instructing means 242 is newly entered on the page of the notebook paper 4. Overwrite handwritten strokes and store them. Specifically, when the handwriting stroke is entered on the notebook paper 4 on which the handwritten stroke has already been entered, the save instruction means 242 determines whether the chapter corresponding to the currently open file and the chapter of the subject corresponding to the notebook paper 4 are present. When it is determined by the determining unit 241 that the files are different, or when the determining unit 241 determines that the currently opened file is new, the handwritten stroke is stored in the chapter file of the subject corresponding to the note paper 4. Let That is, the save instructing unit 242 stores the handwritten stroke in the chapter file corresponding to the notebook paper 4, not in the chapter of the currently opened file.

  On the other hand, if the determination unit 241 determines that the handwritten stroke has been entered in the notebook paper 4 on which the handwritten stroke has not yet been entered, the save instruction unit 242 continues to the page stored in the currently opened file. Then, a new page corresponding to the note paper 4 is created, and the handwritten stroke is associated with the new page and stored in the storage unit 25. If the determination unit 241 determines that there is no file corresponding to the chapter specified by the user, the save instruction unit 242 creates a new file associated with the chapter.

  The display control means 243 of the processing means 24 causes the display means 26 to display a timetable associated with the subjects of the lectures to be performed for each day of the week and each time period. The display control unit 243 is stored in the storage unit 25 in association with the subject acquired by the acquisition unit 245 when the user designates one subject from the plurality of subjects displayed in the timetable. The tree diagram is displayed on the display means 26. That is, the display control unit 243 causes the display unit 26 to display a plurality of chapters and the like for classifying the contents of the subject in a tree diagram for the subject designated by the user. In this case, the display control unit 243 selects the chapter corresponding to the file in which the latest handwritten stroke is stored by the save instructing unit 242 among the plurality of chapters displayed in a tree diagram (that is, the handwritten stroke in the previous lecture). Highlight the chapter).

  Further, the display control unit 243 opens a file associated with the chapter acquired by the acquisition unit 245 when the user specifies a chapter from a plurality of chapters displayed in a tree diagram, and displays the file in the file. The stored handwritten stroke is displayed on the display means 26. In this case, the display control unit 243 causes the display unit 26 to display a predetermined page (for example, the last page) among the pages stored in the file. Further, when the handwritten stroke is entered on the notebook paper 4 with the electronic pen 1, the display control unit 243 displays the handwritten stroke on the display unit 26. Specifically, when it is determined by the determination unit 241 that the handwritten stroke has been entered in the notebook paper 4 on which the handwritten stroke has already been entered, the display control unit 243 stores the relevant file stored in the currently opened file. A page corresponding to the notebook paper 4 is displayed and a handwritten stroke is drawn on the page. Specifically, the display control means 243 determines whether the chapter corresponding to the currently opened file and the chapter of the subject corresponding to the notebook paper 4 when the handwritten stroke is entered on the notebook paper 4 on which the handwritten stroke has already been entered. If it is determined by the determining means 241 that the files are different, or if the determining means 241 determines that the currently opened file is new, the chapter file of the subject corresponding to the note paper 4 is opened. A page corresponding to the notebook paper 4 is displayed and a handwritten stroke is drawn on the page. In other words, the display control unit 243 causes the handwritten stroke to be drawn not on the chapter of the currently open file but on the chapter page corresponding to the notebook paper 4.

  On the other hand, if the determination unit 241 determines that the handwritten stroke has been entered in the notebook paper 4 on which the handwritten stroke has not yet been entered, the display control unit 243 continues to the page stored in the currently opened file. A new page to be displayed is displayed, and a handwritten stroke is drawn on the page. Thus, the display control means 243 corresponds to an example of “first display control means” and “second display control means” in the present invention.

  The informing means 244 of the processing means 24, when the handwriting stroke is entered on the notebook paper 4 with the electronic pen 1 and the judging means 241 determines that the file is not opened (that is, the user designates the chapter of the subject). If not, in other words, if the acquisition unit 245 has not acquired a chapter), the user is notified that no chapter has been designated. In addition, when the determination unit 241 determines that the chapter of the subject corresponding to the note paper 4 in which the handwritten stroke is entered differs from the chapter corresponding to the currently opened file, the notification unit 244 notifies the user of that fact. To inform. That is, the notification unit 244 notifies the user that the chapter specified using the tree diagram is different from the chapter of the subject corresponding to the notebook paper 4 on which the handwritten stroke is written.

[How to create a dendrogram]
Here, a specific example of the above-described tree diagram creation method will be described. A dendrogram is a chart that is expressed in stages by a plurality of units, chapters, sections, etc. according to the contents of each subject, and there are as many as a plurality of subjects. The tree diagram is created by the method described below and stored in the storage means 25.

  In one example, a textbook issuing company creates and distributes a tree diagram for each subject. The computer apparatus 2 downloads and installs the tree diagram thus distributed. In another example, the user creates a tree diagram for each subject by operating the input means 21 (mouse or keyboard) of the computer apparatus 2. In this example, the computer apparatus 2 executes an application for creating a tree diagram, and the user creates a tree diagram using the application.

  In yet another example, a user creates a tree diagram for each subject using a tree diagram creation paper (for example, a paper on which a grid mesh is formed) on which a dot pattern is formed. In this example, the user enters characters indicating names of a plurality of units, chapters, sections, etc., line segments indicating the relationship between the units, chapters, sections, etc. on the tree diagram creation sheet with the electronic pen 1. . Then, the computer device 2 recognizes the tree diagram entered by the user based on the handwritten strokes corresponding to the characters and line segments entered on the tree diagram creation sheet. In this case, the computer device 2 recognizes the names of a plurality of units, chapters, sections, etc. based on the characters and line segments entered on the tree diagram preparation form, and determines the relationship between the units, chapters, sections. By recognizing, the electronic data of the dendrogram is created.

[Display screen example]
Below, with reference to FIGS. 6-12, the example of a screen displayed by the display control means 243 of the above-mentioned processing means 24 is shown.

  FIG. 6 shows an example of a timetable table screen displayed on the display means 26 of the computer apparatus 2. As shown in FIG. 6, the display control means 243 of the processing means 24 causes the display means 26 to display a time schedule table in which the subjects of the lecture to be conducted are associated with each day of the week and each time period. In the timetable, subject names (including abbreviations) indicating the names of subjects of the lecture are displayed.

  For example, the timetable as described above is set by the user performing an operation of inputting a subject name corresponding to each day of the week and each time period using the input means 21 (mouse or keyboard). In this example, the computer apparatus 2 executes an application for setting a timetable, and the user sets a timetable using the application. The time table data set in this way is stored in the storage means 25.

  FIG. 7 shows an example of a screen displayed when the user designates a subject of the timetable. FIG. 7A and FIG. 7B both show examples of screens displayed on the display means 26 of the computer apparatus 2. FIG. 7A is a screen example of a timetable displayed by the display control means 243, similar to FIG.

  Here, as shown in FIG. 7A, a case where the user designates a subject “current company (modern society)” by the input means 21 among a plurality of subjects displayed in the timetable is illustrated. For example, the user designates such subjects by clicking with a mouse or touch-inputting with a touch panel. In this case, the acquisition unit 245 of the processing unit 24 acquires information indicating that the subject designated by the user is “present company”. Then, the display control unit 243 causes the display unit 26 to display the “current company” tree diagram acquired by the acquisition unit 245. That is, the display control unit 243 displays a plurality of units and chapters for classifying the contents of “current office” in a tree diagram on the display unit 26. In the example shown in FIG. 7B, “[1] issues of modern humanity” and “[2] issues of modern society” fall under the unit of “current company”, and “1-1: climate change issues”. And “1-2: Environmental Issues” fall under the chapter “Current Company”. “Chapter” is a subordinate item subordinate to “Unit”, and “Section” is subordinate item subordinate to “Chapter” (“Section” is illustrated in FIG. 7B). Not)

  Also, the display control means 243 has the chapter corresponding to the file in which the latest handwritten stroke is stored by the save instruction means 242 among the chapters of “current company”, that is, the handwritten stroke is written in the previous lecture. Highlight the chapter. In the example shown in FIG. 7 (b), characters indicating the chapter “4-3: Cabinet and Administration” are highlighted in bold and underlined. It should be noted that the highlighting is not limited to bold and underline in this way, and highlighting may be performed using colors, for example.

  The display control means 243 can highlight the subject of the lecture currently being held among the plurality of subjects displayed in the timetable. For example, the display control means 243 selects the subject of the lecture currently being held based on the date and time information acquired from the clock built in the computer device 2 or information on the time period during which each timed lecture is held. Identify and highlight the subject. In the example shown in FIG. 7A, “present company” performed on the 4th Thursday is highlighted. Specifically, the letters “current company” are shown in bold and are highlighted by adding a color in a frame in which “current company” is written. In addition, it is not limited to highlighting by bold type and a color in this way.

  FIG. 8 shows an example of a screen displayed when a user designates one chapter from a plurality of chapters displayed in a tree diagram. FIG. 8A and FIG. 8B both show screen examples displayed on the display means 26 of the computer apparatus 2. FIG. 8A is an example of a tree diagram display screen similar to FIG.

  Here, a case where the user designates a chapter “4-3: Cabinet and Administration” from among a plurality of chapters displayed in a tree diagram using the input means 21 is illustrated. For example, the user designates a chapter by clicking with a mouse or touch-inputting with a touch panel. In this case, the acquisition unit 245 acquires the information of the chapter “4-3: Cabinet and administration” designated by the user via the input unit 21. Then, the display control means 243 opens the file of the chapter “4-3: Cabinet and administration” acquired by the acquisition means 245, and the handwritten strokes stored in the file are displayed as shown in FIG. It is displayed on the display means 26. Specifically, the display control unit 243 causes the display unit 26 to display the last page in the page in which the handwritten stroke is entered for the chapter “4-3: Cabinet and Administration”. For example, the display control unit 243 displays such a page by a window and displays characters corresponding to a subject and a chapter such as “Modern Social Note 4-3: Cabinet and Administration” at the top of the window. Note that the present invention is not limited to displaying the last page as described above, and the first page or the like may be displayed.

  FIG. 9 shows an example of a screen displayed when a handwritten stroke is entered on the notebook paper 4 with the electronic pen 1. FIG. 9A shows an example of the note paper 4, and FIG. 9B shows an example of a screen displayed on the display means 26 of the computer device 2.

  Here, a case where a handwritten stroke is written on the notebook paper 4 on which a handwritten stroke has already been written, that is, a case where a new handwritten stroke is written after the already written handwritten stroke is illustrated. Specifically, as shown in FIG. 9A, a case where a new handwritten stroke is entered in the portion shown in the broken line area B1 is illustrated. In this case, the display control means 243 opens a file storing a page corresponding to the note paper 4 in which the handwritten stroke is entered. Then, as shown in FIG. 9B, the display control means 243 displays a page corresponding to the note paper 4 and draws a handwritten stroke on the page (see the broken line area B2). In addition, when the page corresponding to the notebook paper 4 in which the handwritten stroke is entered is already displayed by designating a chapter from the plurality of chapters displayed in the tree diagram, the display control is performed. The means 243 causes the handwritten stroke to be drawn on the already displayed page because the file is already open without performing the process of opening the file as described above.

  FIG. 10 shows another example of a screen that is displayed when a handwritten stroke is entered on the notebook paper 4 with the electronic pen 1. FIG. 10A shows an example of the note paper 4, and FIG. 10B shows an example of a screen displayed on the display means 26 of the computer device 2.

  Here, a case where a handwritten stroke is written on a notebook paper 4 on which a handwritten stroke has not yet been written, that is, a case where a handwritten stroke is written on a new notebook paper 4 is illustrated. Specifically, as shown in FIG. 10A, a case where a handwritten stroke is entered in a portion indicated by a broken line area C1 is illustrated. In this case, as shown in FIG. 10B, the display control means 243 displays a new page (specifically, a blank page) that is continuous with the page stored in the currently opened file, and A handwritten stroke is drawn on the page (see broken line area C2).

  FIG. 11 shows an example of a folder icon displayed on the display means 26 of the computer apparatus 2. FIG. 11A shows a folder icon 10 in which folders of a plurality of subjects are stored. For example, the folder icon 10 is displayed on the desktop and named “lecture notebook”. When the user selects the folder icon 10 by the input means 21, for example, when the user clicks on the folder icon 10 with a mouse or touch-inputs with a touch panel, as shown in FIG. Icon 11 is displayed.

  When the user selects the file icon 12 by the input unit 21, the display control unit 243 displays the handwritten stroke stored in the selected file on the display unit 26. Specifically, the display control unit 243 causes the display unit 26 to display a predetermined page (for example, the last page) among the pages stored in the selected file.

[Processing flow]
Next, a processing flow according to the first embodiment will be described with reference to FIGS. 13 and 14.

  First, with reference to FIG. 13, a processing flow performed when a subject is specified in the displayed timetable is described.

  First, the display control means 243 of the processing means 24 reads the time schedule table data stored in the storage means 25 and displays the time schedule table on the display means 26 (step S101). Then, the acquisition unit 245 of the processing unit 24 acquires the course designated by the user among the plurality of courses displayed on the timetable by the display control unit 243 (step S102). Specifically, the acquisition unit 245 identifies the subject designated by the user using the input unit 21 based on the timetable data stored in the storage unit 25. For example, the acquisition unit 245 acquires the subject specified by the user clicking with the mouse or touch-inputting with the touch panel.

  Next, the display control unit 243 causes the display unit 26 to display the tree diagram associated with the subject acquired by the acquisition unit 245 and stored in the storage unit 25 (step S103). And the acquisition means 245 acquires the chapter designated by the user among the plurality of chapters displayed in the tree diagram (step S104). For example, the acquisition unit 245 acquires the subject specified by the user clicking with the mouse or touch-inputting with the touch panel.

  Next, the determination unit 241 of the processing unit 24 determines whether there is a file corresponding to the chapter acquired by the acquisition unit 245 (step S105). That is, the determination unit 241 determines whether a file corresponding to the chapter is stored in the storage unit 25. When there is a file corresponding to the chapter acquired by the acquisition unit 245 (step S105; Yes), the display control unit 243 opens the file associated with the chapter and displays the handwritten stroke stored in the file. 26 (step S104). Specifically, the display control unit 243 causes the display unit 26 to display the last page among the pages stored in the file.

  On the other hand, when there is no file corresponding to the chapter acquired by the acquisition unit 245 (step S105; No), the save instruction unit 242 of the processing unit 24 creates a file for the chapter (step S107). Then, the save instruction unit 242 generates an icon of the created file and stores the file in a folder (subject folder) (step S108). Thereafter, the display control unit 243 opens the file created by the save instruction unit 242 (step S109). Specifically, the display control unit 243 causes the display unit 26 to display a blank page.

  Next, a processing flow performed when a handwritten stroke is written on the notebook paper 4 with the electronic pen 1 will be described with reference to FIG. The processing flow shown in FIG. 14 is repeatedly executed each time entry information is generated by the electronic pen 1.

  First, when the user fills in the notebook paper 4 with the electronic pen 1, the electronic pen 1 transmits the generated entry information to the computer device 2. In the computer apparatus 2, when the communication means 22 receives the entry information transmitted from the electronic pen 1, the storage instruction means 242 of the processing means 24 stores the entry information in the storage means 25 (step S201).

  Next, the determination unit 241 of the processing unit 24 determines whether or not the file in which the handwritten stroke is stored is currently opened (step S202). In other words, the determination unit 241 determines whether or not the user has specified a chapter of the subject, that is, whether or not the acquisition unit 245 has acquired the chapter. When the file is not opened (step S202; No), the notification unit 244 of the processing unit 24 notifies the user that the subject chapter is not specified (step S209). For example, the notification unit 244 displays a message indicating that the subject chapter is not specified, a message indicating that the subject chapter should be specified, or the like as an image on the display unit 26, or outputs it as a sound from the speaker. I will let you. Alternatively, the notification unit 244 outputs an alarm sound.

  On the other hand, when the file is open (step S202; Yes), the determination unit 241 determines whether or not the file is a new file (step S203). Specifically, the determination unit 241 determines whether or not the handwritten stroke is not yet stored in the currently opened file. When the file is not new (step S203; No), the determination unit 241 determines whether or not the notebook paper 4 on which the handwritten stroke is written by the electronic pen 1 is a new notebook paper 4 (step S204). Specifically, the determination unit 241 performs such determination based on whether or not the file stored in the storage unit 25 includes the data of the notebook paper 4 written with the electronic pen 1.

  When the note paper 4 entered with the electronic pen 1 is not the new note paper 4 (step S204; No), the determination unit 241 corresponds to the chapter of the subject corresponding to the note paper 4 and the currently opened file. It is determined whether or not the chapter matches (step S205). When the chapter of the note paper 4 and the chapter of the file match (step S205; Yes), the display control unit 243 displays the page corresponding to the note paper 4 stored in the currently opened file, A handwritten stroke is drawn on the page (step S206). Further, the save instruction unit 242 stores the handwritten stroke in association with the page corresponding to the note paper 4.
