<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 and the like from the electronic pen 1, a timetable 3 on which a dot pattern is formed, A plurality of notebook papers 4 each formed with a dot pattern of a different coordinate range, a heading paper 5 for separating the notebook paper 4 by subject, and a multi-hole for binding the timetable 3, the notebook paper 4 and the heading paper 5 File 6.

  The timetable 3 is a table in which lecture subjects (categories) are associated with days of the week and time periods, and a dot pattern is formed in the subject portion. Specifically, in the timetable 3, dot patterns having different coordinate ranges (in other words, unique dot patterns) are formed for each subject. The dot pattern is printed with ink containing carbon that absorbs infrared rays. In the timetable 3, holes for binding by the multi-hole file 6 are formed. Although the timetable 3 is created by the user (details will be described later), the timetable 3 in the completed state is described here. The timetable 3 corresponds to an example of a “sheet” in the present invention.

  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. A plurality of notebook papers 4 are formed with dot patterns in different coordinate ranges (in other words, unique dot patterns), and the coordinate ranges are different from the dot patterns used in the timetable 3. 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 user taps the subject portion of the timetable 3 with the electronic pen 1. At this time, the computer apparatus 2 displays, on the display, a plurality of units and chapters for classifying the contents of the subject in a stepwise manner for the subject tapped by the electronic pen 1. 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.

[Timetable]
With reference to FIG. 2, the structure and creation method of the timetable 3 according to the first embodiment will be described. FIG. 2A shows the seal 8 used for creating the timetable 3. The seal 8 is configured as a paper (sticker mount) having an adhesive on the back surface. A seal of the type that is peeled off from the release paper and stuck as it is is suitable, but a sticker of a type that is stuck after being wet with water may also be used.

  As shown in FIG. 2A, the seal 8 has a plurality of seals 8a to 8k used for a plurality of subjects. The stickers 8a to 8k are printed on the surface with subject names indicating the names of a plurality of subjects to be lectured, and unique dot patterns associated with the respective subjects. In other words, the stickers 8a to 8k are printed with dot patterns having different coordinate ranges for each subject. The subject name is printed with ink that does not absorb in the infrared region. In addition, in the stickers 8a to 8k, the same dot pattern is printed for those printed with the same subject name (four in the example shown in FIG. 2A). That is, the seal 8 is formed with a plurality of sets in which the same subject name and the same dot pattern are printed. The seal 8 is half-cut so that the subject portion to be used can be easily peeled off from the release paper. In the case of a sticker that is applied after being wet with water, a perforated half cut may be used.

  FIG. 2B shows a specific example of the timetable 3 created using the above-described seal 8 (timetable 3 in a completed state). In a state where the seal 8 is not attached to the timetable 3, only the frame lines indicating the locations where the stickers 8 a to 8 k are to be attached are printed in the portion shown in the broken line area A 1, and the part shown in the broken line area A 2 Are printed with characters and frame lines indicating the day of the week and the time limit. When the seal 8 is not attached to the timetable 3, no dot pattern is formed in the timetable 3. In the first embodiment, the timetable 3 is created by the user performing the work of attaching the seal 8 to the portion indicated by the broken line area A1. Specifically, the user completes the timetable 3 by performing an operation of attaching any of the stickers 8a to 8k corresponding to the subject according to the day of the week and the time limit.

  As described above, no dot pattern is printed on the timetable 3 and a dot pattern is printed on the sticker 8, but in the following description, the timetable 3 is a state where the sticker 8 is pasted. For convenience of explanation, it is assumed that a dot pattern is formed in the timetable 3.

[Dot pattern]
The Anoto dot pattern formed on the timetable 3 and the note paper 4 will be described with reference to FIGS. FIG. 3 is a diagram for explaining the relationship between the dots of the dot pattern formed on the timetable 3 and the note paper 4 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. 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 timetable 3 and the notebook paper 4 are determined by the combination of information thus associated.

  FIG. 4A shows an arrangement of a certain dot pattern. As shown in FIG. 4A, 6 × 6 dots within a range of about 2 mm in length and breadth form a unique pattern no matter what part of the timetable 3 or notebook paper 4 is taken 6 × 6 dots. Are arranged as follows. The dot pattern formed by these 36 dots holds position coordinates (for example, where the dot pattern is on the timetable 3 or the notebook paper 4). FIG. 4B is a diagram in which each dot shown in FIG. 4A is converted into a value associated with the regularity shown in FIG. 3 according to the shift direction from the reference position of the lattice. This conversion is performed by the electronic pen 1 that captures an image of a dot pattern.

[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 the user touches the pen tip portion 103 of the electronic pen 1 against the notebook paper 4 to enter a stroke (handwritten stroke) or the electronic pen 1. The pen nib portion 103 is brought into contact with the timetable 3 and tapped (tapping the timetable 3 with the nib 103). Here, the contact of the pen tip portion 103 of the electronic pen 1 with the timetable 3 or the notebook paper 4 is referred to as “pen down”, and the pen up portion 103 is separated from the contact (contact) state. Call it. 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 or taps the timetable 3, that is, the writing pressure. 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 user writes characters or the like on the notebook paper 4 with the electronic pen 1 or taps on the timetable 3, the pen pressure is applied to the pen tip portion 103, and the pressure sensor 107 detects a writing pressure higher than a predetermined value. On the other hand, the processor 108 determines that the user has started filling in and activates the LED 105 and the CMOS camera 106. 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. Further, when the user finishes entering one stroke and moves the electronic pen 1 away from the timetable 3 or the notebook paper 4, the pressure sensor 107 detects a 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 point portion 103 on the timetable 3 and the notebook paper 4. The region is slightly deviated from the position where the pen tip 103 contacts the timetable 3 or the note 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, or the like are printed on the timetable 3 or the notebook paper 4, the processor 108 can recognize the dot pattern because the printed ink does not absorb in the infrared region. 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.

  The processor 108 performs X and Y coordinates (hereinafter referred to as “time table 3” and “notebook 4” on the timetable 3 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. Simply referred to as “positional coordinates” or “coordinate information”). 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. 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 in the timetable 3 and the notebook paper 4 does not overlap in the timetable 3 or the notebook paper 4, when the user enters characters or the like with the electronic pen 1, It is possible to specify the position on the timetable 3 and the note paper 4 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”.

[Computer device]
Next, the computer apparatus 2 will be described. The computer device 2 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 ROM and RAM, a display, a personal computer including a mouse and a keyboard, and the like . FIG. 6 is a functional block diagram of the computer apparatus 2. 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 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. Furthermore, the storage unit 25 stores coordinate definition information in which a plurality of subjects are associated with coordinate ranges of dot patterns assigned to the plurality of subjects. 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 determination unit 241 of the processing unit 24 fills in either the timetable 3 or the notebook paper 4 by the electronic pen 1 based on the entry information received from the electronic pen 1 by the communication unit 22 (including both taps and strokes). Determine whether it was done. Specifically, the determination unit 241 includes coordinate definition information stored in the storage unit 25 (specifically, coordinate definition information indicating coordinate ranges of dot patterns assigned to the plurality of notebook papers 4, and a plurality of pieces of coordinate definition information). By referring to the coordinate definition information indicating the coordinate range of the dot pattern assigned to the subject, it is determined which of the subject of the timetable 3 and the note paper 4 has been entered by the electronic pen 1. When the determination unit 241 determines that the subject of the timetable 3 is entered with the electronic pen 1, the subject is specified. Specifically, the determination unit 241 associates the plurality of subjects and the coordinate range of the dot pattern stored in the storage unit 25 when the user taps on the subjects in the timetable 3 with the electronic pen 1. By referring to the coordinate definition information, the subject tapped by the electronic pen 1 is specified. Thus, the determination unit 241 corresponds to an example of “category specifying unit” in the present invention.

  On the other hand, when the determination unit 241 determines that the note paper 4 has been filled in with the electronic pen 1, the determination unit 241 determines whether or not the note paper 4 is a new note 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 determines whether or not the file stored by the save instruction unit 242 to be described later includes the data of the note paper 4 in which the handwritten stroke is written by the electronic pen 1. Make a decision.

  The acquisition unit 245 of the processing unit 24 acquires a chapter designated 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 storage instruction unit 242 of the processing unit 24 stores the handwritten stroke entered with the electronic pen 1 in the storage unit 25 as a file associated with the chapter acquired by the acquisition unit 245. 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. 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 there is no file corresponding to the chapter acquired by the acquisition unit 245, the save instruction unit 242 creates a new file associated with the chapter.

  The display control unit 243 of the processing unit 24 displays the tree diagram associated with the subject and stored in the storage unit 25 on the display unit 26 when the user taps the subject in the timetable 3 with the electronic pen 1. Let That is, for the subject tapped with the electronic pen 1, 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 stages. 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. The display control unit 243 causes the display unit 26 to display the handwritten stroke when the handwritten stroke is entered on the notebook paper 4. Specifically, the display control means 243 stores the page corresponding to the note paper 4 when the judgment means 241 determines that the handwriting stroke has been entered on the note paper 4 on which the handwriting stroke has already been entered. The file is opened, a page corresponding to the note paper 4 is displayed, and a handwritten stroke is drawn on the page. 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.

  The notifying means 244 of the processing means 24 determines that the handwriting stroke has been entered on the notebook paper 4 on which the handwritten stroke has not yet been entered, and the judging means 241 determines that the subject has not been opened (that is, the subject has not been opened). If no chapter is specified), the user is notified that the chapter is not specified.

[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]

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.

  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 by the information processing system according to the first embodiment will be described with reference to FIG. The processing flow shown in FIG. 13 is repeatedly executed each time entry information is generated by the electronic pen 1.

  First, when the user fills in the timetable 3 and the note paper 4 (including both taps and strokes) 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 unit 22 receives the entry information transmitted from the electronic pen 1, the storage instruction unit 242 of the processing unit 24 stores the entry information in the storage unit 25 (step S101).

  Next, the determination unit 241 of the processing unit 24 determines which of the subjects in the timetable 3 and the notebook sheet 4 is filled with the electronic pen 1 (step S102). Specifically, the determination unit 241 includes coordinate definition information stored in the storage unit 25 (specifically, coordinate definition information indicating coordinate ranges of dot patterns assigned to the plurality of notebook papers 4, and a plurality of pieces of coordinate definition information). By referring to the coordinate definition information indicating the coordinate range of the dot pattern assigned to the subject, it is determined which of the subject of the timetable 3 and the note paper 4 has been entered by the electronic pen 1.

  When the subject of the timetable 3 is entered by the electronic pen 1 (step S102: subject of the timetable), the determination unit 241 identifies the subject tapped by the electronic pen 1, and the display control unit 243 of the processing unit 24 Then, the chapter of the identified subject is displayed on the display means 26 in a tree diagram (step S103). Then, the acquisition unit 245 of the processing unit 24 acquires a chapter designated by the user among a plurality of chapters displayed in a tree diagram (step S104). Subsequently, the determination unit 241 determines whether a chapter file designated by the user is stored in the storage unit 25 (step S105).

  When the chapter file specified by the user is stored (step S105; Yes), the display control unit 243 opens the file associated with the chapter and displays the handwritten stroke stored in the file as the display unit 26. (Step S106). 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, if the chapter file designated by the user is not stored (step S105; No), the save instruction unit 242 creates a file used 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.

  On the other hand, when the electronic pen 1 fills in the note paper 4 (step S102: note paper), the determination unit 241 determines whether or not the note paper 4 is a new note paper 4 (step S110). . 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 filled in with the electronic pen 1 is not the new note paper 4 (step S110; No), the display control unit 243 opens a file including a page corresponding to the note paper 4 and the note paper 4 A page corresponding to is displayed on the display means 26 (step S111). Then, the display control unit 243 draws a handwritten stroke on the displayed page, and the save instruction unit 242 stores the handwritten stroke in association with the page (step S112).

  On the other hand, when the notebook paper 4 entered with the electronic pen 1 is a new notebook paper 4 (step S110; Yes), the determination unit 241 determines whether or not the file is open (step S113). In other words, the determination unit 241 determines whether or not the chapter of the subject is specified by the user.

  When the file is open (step S113; Yes), the save instructing unit 242 continues the page (specifically, the last page) stored in the currently open file for the new note paper 4 And the created page is stored in a file (step S114). When no page is stored in the currently opened file, that is, when the new notebook paper 4 corresponds to the first page, the save instructing unit 242 selects a page that is continuous with the page stored in the file. Create the first page without creating it. Next, the display control unit 243 draws a handwritten stroke on a new page (blank page), and the save instruction unit 242 stores the handwritten stroke in association with the page (step S115).

  On the other hand, when the file is not opened (step S113; No), the notification unit 244 of the processing unit 24 notifies the user that the subject chapter is not specified (step S116). For example, the notification unit 244 causes the display unit 26 to display a message indicating that a subject chapter is not specified as an image, or output the message from a speaker. Alternatively, the notification unit 244 outputs an alarm sound.

[Effects of First Embodiment]
According to the information processing system according to the first embodiment described above, it is possible to appropriately display a unit or chapter corresponding to the content of a subject in a tree diagram for each subject. Specifically, for a subject designated by the user using the timetable 3, the unit and chapter of the subject can be appropriately displayed in a tree diagram. Therefore, the user can easily grasp the configuration related to the contents of each subject. Further, according to the first embodiment, handwritten strokes written on the notebook paper 4 by the electronic pen 1 can be classified and stored appropriately for each chapter of each subject (that is, the handwritten strokes can be digitized). At the same time, handwritten strokes can be appropriately displayed for each chapter of each subject. Specifically, the handwritten stroke entered by the electronic pen 1 can be stored in association with the chapter designated by the user by referring to the screen on which the tree diagram is displayed, and is designated as such. The handwritten stroke can be appropriately displayed according to the chapter that has been made.

[Modification of First Embodiment]
In the above, the seal 8 is shown as an example of the “print medium” in the present invention. In another example, a tape can be used as a “print medium” instead of such a seal 8. Specifically, a tape having a dot pattern in a different coordinate range associated with each of a plurality of subjects printed on the front surface and an adhesive layer formed on the back surface can be used.

In the above, the timetable 3 is shown as an example of the “sheet” in the present invention. In another example, instead of the timetable 3 in which a plurality of subjects are associated with a day of the week and a time limit, a sheet in which only a plurality of subjects are formed as a “sheet” (for example, a sheet in which only a plurality of subject names are arranged) ) Can be used. Specifically, a sheet in which a plurality of subject names and unique dot patterns associated with each of the plurality of subjects are formed can be used.
Moreover, in the said embodiment, the process means 24 attaches | subjects a page number for every page of each subject, and you may make it display the page number on each page. Further, the processing unit 24 may detect a finger operation by a touch panel provided on the display unit 26 and perform a page turning process.

Second Embodiment
Next, a second embodiment according to the present invention will be described. In the second embodiment, the configuration and creation method of the timetable is different from the first embodiment. Specifically, in the first embodiment, the timetable 3 is created by the user attaching the sticker 8, but in the second embodiment, the user enters the subject name with the electronic pen 1. To create a timetable.

  In the following, the configuration different from the first embodiment will be mainly described, and the description of the same configuration as the first embodiment will be omitted as appropriate. That is, components and processes not specifically described are the same as those in the first embodiment.

  With reference to FIG. 14, the structure and creation method of the timetable 3a according to the second embodiment will be described. FIG. 14 shows a specific example of the timetable 3a in which subjects are entered (that is, the timetable 3a in a completed state).

  In the timetable 3a according to the second embodiment, a plurality of fields for entering the subject name are provided in the portion indicated by the broken line area D1 (that is, a frame line for entering the subject name is printed therein) In addition, dot patterns having different coordinate ranges are printed in these columns. In addition, characters and a frame line indicating the day of the week, a time limit, and the like are printed in a portion indicated by a broken line area D2. Thus, unlike the timetable 3 according to the first embodiment, the timetable 3a according to the second embodiment is printed with a dot pattern.

  In the second embodiment, the timetable 3a is created by the user performing the work of entering the subject name with the electronic pen 1 in the portion indicated by the broken line area D1. Specifically, the user performs an operation of entering the subject name corresponding to the day of the week and the time period with the electronic pen 1 in a column provided in the portion indicated by the broken line area D1 (that is, in the printed frame). This completes the timetable 3a.

  As described above, when the user enters the subject name in the timetable 3a with the electronic pen 1, the computer device 2 recognizes the entered subject name as characters. Specifically, the computer apparatus 2 receives entry information corresponding to the entry into the timetable 3a by the electronic pen 1, and based on the handwritten stroke corresponding to the entry information, the entered subject name is a publicly known method. Character recognition by And the computer apparatus 2 memorize | stores the coordinate definition information which matched the coordinate range of the dot pattern formed in each of the several column of the timetable 3a, and the subject name filled in each of the said several column. . Thereafter, the computer apparatus 2 performs the same processing as that described in the first embodiment (see FIGS. 7 to 13).

  According to the second embodiment described above, similarly to the first embodiment, the unit and chapter of the subject can be appropriately displayed on the tree diagram for the subject designated by the user using the timetable 3a. . Further, handwritten strokes entered on the notebook paper 4 by the electronic pen 1 can be classified and stored appropriately for each chapter of each subject, and the handwritten stroke can be appropriately displayed for each chapter of each subject. it can. Furthermore, in the second embodiment, since the timetable 3a is created by entering the subject name, it is not necessary to use the seal 8 as shown in the first embodiment, so that the information processing system is simple and inexpensive. Can be configured.

[Modification of Second Embodiment]
In the above, an example using coordinate definition information in which a subject and a dot pattern coordinate range are associated is shown, but not only a subject but also coordinate definition information in which a day of the week and a time period and a dot pattern coordinate range are associated is used. May be. In the timetable 3a according to the second embodiment, since dot patterns having different coordinate ranges are formed in a plurality of fields for entering subject names, there are as many unique dot patterns as combinations of days of the week and time periods. Will exist. Therefore, it can be said that from the dot pattern formed in the plurality of columns, not only the entered subject but also the day of the week and the time limit corresponding to the subject can be specified. Therefore, in another example, coordinate definition information in which a subject, a day of the week, a time limit, and a coordinate range of a dot pattern are associated can be used. In this way, when the subject of the timetable 3a is tapped with the electronic pen 1, it becomes possible to specify not only the subject but also the day of the week and the time limit on which the subject is implemented. Incidentally, in the first embodiment, since the same dot pattern is assigned to the same subject, when the subject of the timetable 3a is tapped by the electronic pen 1, basically only the subject can be specified. The day of the week and time limit cannot be specified.

  In yet another example, it is possible to use the timetable 3a in which dot patterns are formed not only in the field for entering the subject name but also in the day part. That is, you may form the dot pattern of the different coordinate range matched with each of several day of the week (Monday-Friday) in the day part of the timetable 3a. By doing so, for example, when the day of the week of the timetable 3a is tapped with the electronic pen 1, it becomes possible to quickly specify a plurality of subjects performed on that day of the week.

<Third Embodiment>
Next, a third embodiment according to the present invention will be described. The third embodiment is different from the first embodiment in the screen displayed when the timetable is tapped with the electronic pen 1. Specifically, the third embodiment relates to a screen displayed when the timetable 3a shown in the second embodiment is used and the timetable 3a is tapped with the electronic pen 1.

  In the third embodiment, when the subject of the timetable 3a is tapped with the electronic pen 1, the computer device 2 identifies the subject, identifies the day of the week and the time limit, and forms a plurality of chapters of the identified subject. While displaying in a figure, among the plurality of chapters displayed in a tree diagram, a chapter in which a handwritten stroke is written on a specified day of the week and time period is highlighted. In the third embodiment, when the day of the week of the timetable 3a is tapped with the electronic pen 1, the computer apparatus 2 displays the handwritten strokes that have been written side by side for all subjects implemented on the day of the week.

  In the following, the configuration different from the first embodiment will be mainly described, and the description of the same configuration as the first embodiment will be omitted as appropriate. That is, components and processes not specifically described are the same as those in the first embodiment.
