In this way, the electronic pen 10 acquires position information indicating which position on the Anoto sheet 20 is entered when the user performs handwriting input, and records the position information in the memory 125.

  Then, the wireless communication system 133 of the electronic pen 10 transmits the position information recorded in the memory 125 to the PC 30 (S2). At this time, the position information may be sequentially transmitted to the PC 30 while being written on the Anoto sheet 20, or the position information may be collectively transmitted to the PC 30 after entering characters or symbols.

  Here, a case will be described in which the schedule information created in advance by the schedule management unit 315 of the PC 30 or the schedule information registered in the storage unit 33 after the schedule management unit 315 has created is deleted. For example, it is assumed that a strikethrough is registered in advance in the storage unit 33 as a deletion font shape for deleting a character or symbol registered for each date as schedule information. In this case, a strikethrough is entered so as to overlap the character or symbol to be deleted.

Then, the communication unit 32 of the PC 30 receives the position information transmitted from the electronic pen 10 (S2). When the position information transmitted from the electronic pen 10 is received by the communication unit 32, the application unit 31 of the PC 30 is activated.
Next, based on the position information received by the communication unit 32, the date analysis unit 312 analyzes which date information corresponds to the date information (S3). Specifically, the date analysis unit 312 compares the position information acquired by the position acquisition unit 141 of the electronic pen 10 with the PAD file stored in the storage unit 33, so that the electronic pen 10 Analyze what month and day the entered character or symbol corresponds to identify date information.

  Here, the Anoto paper 20 is printed with a different dot pattern 205 for each Anoto paper 20, and the paper address 21 is different for each Anoto paper 20. In each area of the entry fields 221, 222, and 223 of the Anoto sheet 20, a dot pattern 205 indicating position information corresponding to the position where the electronic pen 10 is filled is formed. Correspondence information in which position information and date information are associated with each other is registered in the storage unit 33 of the PC 30 in advance. That is, information regarding each area of each entry column 221, 222, 223 corresponding to the date information is stored in the storage unit 33 of the PC 30 as a PAD file as correspondence information.

  In the schedule entry field 220 corresponding to February 6, 2006 shown in FIG. 2, the time entry field 221 is the area name “11h”, the category entry field is the area name “11c”, and the note entry field is the area name “11n”. Is defined. Similarly, in the schedule entry field 220 corresponding to February 7, 2006, the time entry field 221 is the area name “12h”, the category entry field is the area name “12c”, and the note entry field is the area name “12n”. Define. That is, different dot patterns 205 are formed in all of the entry fields provided for each date.

  Then, the date analysis unit 312 of the PC 30 compares the position information acquired by the position acquisition unit 141 of the electronic pen 10 with the PAD file, and collates the characters or symbols entered by the electronic pen 10 with what month. Analyze how many days are supported and identify date information. As described above, the date information corresponding to the characters or symbols written on the Anoto paper 20 can be specified without writing the date on the Anoto paper 20 with the electronic pen 10.

  Next, the character / symbol analysis unit 313 analyzes the character or symbol entered by the electronic pen 10 based on the position information received by the communication unit 32 (S4). Specifically, the character / symbol analysis unit 313 compares the amount of change in the position information received by the communication unit 32 with each shape of a plurality of reference fonts registered in advance in the storage unit 33, and the electronic pen The character or symbol entered by 10 is analyzed. As a result, it is possible to easily make the character or symbol entered on the Anoto sheet 20 correspond to the reference font, create schedule information, and register it in the storage unit 33 of the PC 30.

  As a result, the characters or symbols entered in the time entry field 221 are converted into numeric data corresponding to the reference font, and the characters or symbols entered in the category entry field 222 are converted into symbol data corresponding to the reference font. The characters or symbols entered in the note entry field 223 are converted into character data corresponding to the reference font.

  Here, when the characters or symbols entered in the time entry field 221 are entered in a range not corresponding to “0:00” to “23:59”, or nothing is entered in the time entry field 221. In this case, the character / symbol analysis unit 313 treats the character or symbol entered in the time entry field 221 as an all-day schedule without converting it into numeric data corresponding to the reference font. The converted number is used as the scheduled start time.

  The characters or symbols entered in the category entry field 222 are converted into symbol data corresponding to the reference font, and then converted into a character string set for each symbol. That is, for example, “◯” is converted into “conference”, “×” is converted into “going out”, “Δ” is converted into “business trip”, and “◎” is converted into “private”. These settings are registered in advance in the storage unit 33 of the PC 30. In addition, when a symbol other than preset “◯”, “×”, “Δ”, and “」 ”is entered in the category entry column 222, the category is not set. The converted character string is used as a category for classifying the schedule.

  The characters or symbols entered in the note entry field 223 are converted into character data corresponding to the reference font and used as the scheduled subject name and planned content. When the character / symbol analysis unit 313 fails to analyze the character or symbol entered in the note entry field 223, the note entry field 223 becomes blank. Here, the character or symbol entered in the note entry field 223 is recognized by the character / symbol analysis unit 313 and converted into character data corresponding to the reference font. Alternatively, the symbol may be stored in the storage unit 33 as an image. In this way, by storing the characters or symbols entered in the note entry field 223 as an image in the storage unit 33, the schedule is reflected in a form reflecting the personality of the user who enters the characters or symbols, such as the character shape. Registration is made.

  Next, the application unit 31 analyzes whether or not there is a strikethrough in each entry field 221, 222, 223 of the schedule entry field 220 (S5). That is, the character / symbol analysis unit 313 stores in advance the storage unit 33 of the PC 30 in order to delete the amount of change in the position information received by the communication unit 32 and the character or symbol in the schedule information associated with each date. The shape of the registered deletion font is compared to analyze whether the character or symbol entered by the electronic pen 10 corresponds to the deletion font.

Here, it is assumed that the strikethrough is registered in advance in the storage unit 33 as a deletion font shape for deleting a character or symbol registered for each date as schedule information. At this time, the strikethrough refers to, for example, a one-stroke writing that occupies 80% or more of the width of the note entry field 223. In addition, since the reference | standard with respect to the height of the note entry column 223 is not prescribed | regulated, a strikethrough is not specified to a horizontal line.
If there is a strikethrough, the date and the time entered in the time entry field 221 are searched from the registered schedule information (S10). However, if the time is not entered in the time entry field 221, the search is not performed. If there is no plan that matches the registered schedule information, the search process is terminated.

  When the application unit 31 analyzes that there is a strikethrough in each entry field 221, 222, 223 of the schedule entry field 220 (S10), the schedule management part 315 searches for a schedule created or registered by the schedule management part 315. , Delete the one that matches the entered time from the schedule. That is, when the character / symbol analysis unit 313 analyzes that the character or symbol entered by the electronic pen 10 corresponds to the deletion font, the schedule management unit 315 displays the character or symbol in the schedule information corresponding to each date. delete. Then, the process ends. Note that the deletion of the schedule is executed by entering the time in the time entry field 221 and entering the strikethrough in the note entry field 223 regardless of the processing method of S1. Also, since there are no more than two schedules starting at the same date and time, if the date and time can be specified, they can be deleted.

On the other hand, when there is no strikethrough, processing is performed according to the processing method set in the application unit 31 (S6 to S9).
Next, the application unit 31 checks whether or not characters or symbols are entered in the required entry field (S6). Specifically, in the time entry field 221, the category entry field 222 or the note entry field 223 of the schedule entry field 220, at least one entry field is set as the required entry field in the storage unit 33 of the PC 30. When a character or symbol is entered in the required entry field, the application unit 31 processes it, and schedule registration (S9) or schedule export process (S8) is performed. On the other hand, when no character or symbol is entered in the required entry field, the application unit 31 does not process, and the schedule registration (S9) or the schedule export process (S8) is not performed.

  In addition, regarding the deletion of the schedule, the entry in the required entry field is irrelevant. If the time entry field 221 is filled with time and the note entry field 223 is filled with a strikethrough, the application unit 31 is registered. Search for existing events, and delete any events that have the same date and time.

  Next, the processing method determination unit 314 determines whether to perform any of the scheduled registration process or the scheduled export process according to the processing method set in S1 (S7). That is, the processing method determination unit 314 determines whether to register the schedule information created by the schedule management unit 315 in the storage unit 33 or to perform export processing.

  Here, when the schedule registration process or the schedule export process is performed, the time entered in the time entry field 221 is set as the scheduled start time, the letters or symbols entered in the note entry field 223 are set as the subject, the category The category entered in the entry field 222 is set as the category name.

  When the processing method determination unit 314 determines to perform the scheduled export process (S7), the scheduled export process is performed (S8). Specifically, when the communication unit 32 receives position information transmitted from the electronic pen 10, the schedule management unit 315 creates schedule information by associating characters or symbols entered by the electronic pen 10 for each date, The communication unit 32 exports the schedule information to a transmission destination designated in advance by an output method designated in advance according to the control of the CPU 316.

  In the description of the present embodiment, it has been described that a method such as vCal or CSV is used as the output method, but the present invention is not limited to this. If an e-mail address is set in advance, the e-mail can be sent simultaneously with the schedule export process. Recently, a general mobile phone is compatible with the vCal format, so that an export process can be performed in the vCal format, and the schedule can be easily registered in the mobile phone by sending it to the mobile phone by e-mail.

  When the processing method determination unit 314 determines to perform the scheduled registration process (S7), the scheduled registration process is performed (S9). Specifically, the schedule management unit 315 creates schedule information by associating characters or symbols entered by the electronic pen 10 for each date according to the analysis results of the date analysis unit 312 and the character / symbol analysis unit 313. Then, the created schedule information is registered in the storage unit 33 according to the control of the CPU 316. In addition, when the schedule entry field 220 of the Anoto sheet 20 is divided into a plurality of entry fields 221, 222, and 223, the schedule registration unit 315 sets the characters or symbols entered by the electronic pen 10 for each date and Schedule information is created in association with each of the plurality of areas, and the created schedule information is registered in the storage unit 33 under the control of the CPU 316. Only when it is determined that a character or symbol has been entered in the required entry field, the schedule management unit 315 uses the date or symbol entered by the electronic pen 10 as schedule information for each date and for each of a plurality of regions. sign up.

  Here, in the scheduled registration process, characters, symbols, and images obtained by converting data entered in the time entry field 221, the category entry field 222, and the note entry field 223 are used. The schedule information stored in the storage unit 33 of the PC 30 can be viewed using the display unit 34 when the user needs it. 6 and 7 are diagrams showing an example of a schedule information display screen of the schedule management system according to the embodiment of the present invention.

  As shown in FIG. 6, the registered schedule is displayed on a monthly calendar, and details are displayed when each schedule is opened. The display method is not limited to a monthly calendar, and may be a weekly display. Further, the schedules may be displayed by sorting by category name or by date. When one schedule is displayed from the list display, individual display as shown in FIG. 7 is performed. As shown in FIG. 7, the schedule information is displayed in the subject, start time, text, and category columns.

  As described above, in the schedule management system according to the present invention, the PC 30 receives a plurality of communication units 32 that receive the position information transmitted from the electronic pen 10 and a plurality of pieces of position information that the communication unit 32 receives. Of the date information, a date analysis unit 312 that analyzes which date information corresponds to, and a character / symbol that analyzes a character or symbol entered by the electronic pen 10 based on position information received by the communication unit 32 An analysis unit 313, a schedule management unit 315 that creates schedule information by associating characters or symbols entered by the electronic pen 10 for each date according to the analysis results of the date analysis unit 312 and the character / symbol analysis unit 313 The schedule information can be easily input for each date, and the schedule information can be exchanged between the Anoto paper 20 and the PC 30. Synchronized and can be managed.

Next, a specific example of entry on the Anoto sheet 20 will be described with reference to the drawings. FIG. 8 to FIG. 10 are diagrams showing examples of filling in an annotation sheet.
FIG. 8 shows a most typical entry example when performing a schedule registration process or a schedule export process. When performing the schedule registration process or the schedule export process, the schedule is entered in the same manner. Specifically, as shown in FIG. 8, the scheduled start time is entered in the time entry field 221, a symbol for setting the category name is entered in the category entry field 222, and the subject and the like are entered in the note entry field 223. Fill out. However, the time entry field 221 or the category entry field 222 need not be entered.

When not filling in the time entry field 221, it is handled as an all-day schedule. If the category entry field 222 is not filled, no classification by category is performed.
The handwritten characters or symbols entered in the entry fields 221, 222, and 223 are converted into character data of standard fonts registered in advance in the storage unit 33 and used. The note entry field 223 is not limited to conversion to character data in a standard font, and may be stored and used as an image.

  FIG. 9 shows an example of entry when a schedule is deleted. Enter the scheduled start time to be deleted in the time entry field 221, and enter a strikethrough in the note entry field 223. When deleting a schedule, the entry in the category entry field 222 is not particularly necessary, and is not used even if it is entered. Further, even if something other than the strikethrough is entered in the note entry field 223, it is not used. The application unit 31 calculates the ratio of the strikethrough to the width of the note entry field 223, and determines that the strikethrough exceeds a certain value. If it is less than a certain value, it is not considered a strikethrough and the schedule is not deleted. Here, for example, the strikethrough must occupy 80% of the width of the note entry field 223, and if it is less than 80%, the strikethrough is not considered. Since the strikethrough has no particular reference in height, it does not have to be limited to drawing one horizontal line.

  FIG. 10 is an example in the case where each entry column 221, 222, 223 is protruded when a schedule is entered. If the protruding portion is not processed, the entry in FIG. 7 protrudes up and down, so that three schedules are registered, and two of them are registered as meaningless schedules. The application unit 31 determines whether characters or symbols are entered in a preset effective area. Specifically, for example, the ratio of the height of the handwritten character or symbol entered to the height of the note entry field 223 is calculated, and if it exceeds a certain value, the character or symbol is correctly entered. Shall be. Characters or symbols entered outside the effective area are not analyzed by the date analysis unit 312 and the character / symbol analysis unit 313. That is, if it does not exceed a certain value, all the entries are overwritten, and the handwritten data of the overhanging portion is deleted. The same processing is performed on the time entry field 221 and the category entry field 222, and the entry that protrudes from all the entry fields 221, 222, and 223 is deleted. Here, with respect to the height of each entry column 221, 222, 223, entry less than 50% is regarded as an entry that protrudes in error, and processing of handwritten data, that is, date analysis, is performed after the protruding portion is deleted. The analysis is performed by the unit 312 and the character / symbol analysis unit 313.
