Description

  The present invention relates to a handwritten data processing apparatus.

  Conventionally, instead of a notebook and a memo pad, there are an electronic notebook using a keyboard input and an electronic memo pad using a light pen. In addition, portable electronic information storage devices (PDA, notebook personal computers, etc.) with improved functions have been developed by reducing the size and weight of computers and increasing the size and capacity of storage media. If you carry such a device and use it, you can write down some notes on the spot when you have an idea.

  For example, the invention disclosed in Patent Document 1 is a portable electronic information storage device that enables recording of characters and figures by simple handwriting input. That is, the invention disclosed in Patent Document 1 detects the coordinate position of a writing instrument by touching a writing instrument such as a general pen and a transparent touch panel provided on the liquid crystal display unit, and samples the detected coordinate position. The captured characters and figures are displayed on the liquid crystal display unit and stored.

  The invention disclosed in Patent Document 2 is an apparatus that freely edits input characters and stores many handwritten characters. That is, in the invention disclosed in Patent Document 2, a display panel having a display surface in which Cartesian coordinates are preset and a touch panel having an input surface in which Cartesian coordinates are preset are arranged so as to overlap each other. . And at the time of the handwritten input which instruct | indicates an input surface continuously, the invention disclosed by patent document 1 displays the coordinate point of the display surface which corresponds with the instruct | indicated several coordinate point. After completion of handwriting input, the invention disclosed in Patent Document 1 creates stroke data composed of coordinate points extracted based on a predetermined criterion from among a plurality of coordinate points output from the touch panel during handwriting input. After the cursor display position, the stroke data is converted into a size corresponding to the line width set on the display surface and displayed.

  The invention disclosed in Patent Document 3 is an apparatus that uses a touch pad and appropriately switches between a cursor movement operation and a handwriting input operation on a display screen in an electronic information device such as a personal computer. That is, in the invention disclosed in Patent Document 3, when a predetermined area of the touchpad is touched with a pen, the control unit is set to the handwriting recognition mode, and the locus of coordinate data detected by the touchpad is detected coordinates. It is an invention in which handwritten characters or symbols are recognized in accordance with the locus of the coordinate data stored sequentially in the memory. Further, in the invention disclosed in Patent Document 3, in a normal input mode in which a predetermined area of the touch pad is not touch-operated by the pen, the liquid crystal display is relatively associated with the coordinate data detected by the touch pad. This is an invention in which the movement position of the cursor displayed on the screen is controlled.

  However, since the invention disclosed in Patent Document 1 simply captures characters and graphics input to the touchpad and displays them as they are, it cannot input a graphic that is larger than the size of the touchpad. Further, the invention disclosed in Patent Document 2 displays characters and figures input on the input surface after converting them to a size corresponding to the line width of the display surface, so that the line width of the display surface is usually handwritten. Even if the width cannot be entered, characters and figures can be input by hand, but characters and figures exceeding the line width cannot be input. Since the invention disclosed in Patent Document 3 only recognizes and displays handwritten characters or symbols input to the touchpad, it cannot recognize handwritten characters or symbols larger than the size of the touchpad.

  As described above, the portable electronic information storage device and the disclosed invention can write down a memo to some extent when an idea comes up, but cannot write down a floating image as it is.

  Here, for example, it is considered to write down an image floating in the user's mind as it is on a mobile phone as a portable electronic information storage device. For example, the display screen of a mobile phone has a resolution of 240 × 400 or the like. If 16 × 16 dots are assigned to each character so that the characters can be visually recognized, the floating image can be written down using characters and figures corresponding to 375 characters (15 characters × 25 characters). It should be possible. However, in order to perform handwriting input in order to write down a floating image as it is, an area for handwriting input is required. Therefore, in the above-described method, the image is used by fully utilizing the resolution of the display screen. You cannot write down. Even in the method of converting the input image to the resolution of the display screen, it is not possible to input a graphic or the like of the image that exceeds the input area, and thus it is not possible to write down the floating image as it is. Furthermore, in order to write down information exceeding the display capacity of the display screen (for example, 375 characters), a method of converting an image into a character code and converting it into a text file is a process of inputting, converting, and recognizing floating characters. Since it is necessary to make the user make many selections, the user's operation does not go smoothly, and often interrupts the user's inspiration.

  Therefore, for example, even if the space of the handwriting input unit is a space that can input only about one handwritten character, it is possible to input and display a graphic or character larger than the handwriting input unit, and further restrict the display screen. There is a demand for a device that can directly input a large amount of information beyond the range.

[Embodiment 1]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing characteristics of a handwritten data processing apparatus 10 according to an embodiment of the present invention. The example shown in FIG. 1 is an example showing the correspondence between the first display means (display section 2014 described later) of the handwritten data processing apparatus 10 and the input tablet 202 of the handwriting input means (handwriting input section 12 described later). It is.

  The display unit 2014 has a predetermined number of cells 101 (hereinafter, a cell configured in the display unit 2014 is referred to as a cell 101, and a cell at a specific position among the configured cells, for example, a cell in the first row and the first column is a cell. C101) is configured in a matrix. The display unit 2014 displays an image for each configured cell 101. The handwriting input unit 12 includes an input display device 201 and an input tablet 202 that is disposed in front of the input display device 201 and has translucency. The input tablet 202 includes a normal input area 211 in which the locus of the stylus pen 301 can be input by handwriting, and an extended input area 221 (hereinafter referred to as the entire extended input area 221) surrounded by the outer periphery of the normal input area 211. It is called an extended input area 221, and specific sections of the extended input area 221 are extended input areas 221-1, 221-2, 221-3, 221-4, and extended input areas 221 -A, 221 -B, 221. -C, 221-D).

  1 indicate a stylus in which the normal input area 211 of the input tablet 202 and one cell C704 of the plurality of cells 101 configured in the display unit 2014 are input to the normal input area 211. This indicates that the trajectory 401 of the pen 301 is associated so as to be displayed in the one cell C704. Furthermore, the broken lines 421 to 428 in FIG. 1 divide the extended input area 221 into predetermined sections, and each of the divided sections and each cell in contact with one cell C704 associated with the normal input area 211, , The locus of the stylus pen 301 input to one section of the extended input area 221 is associated with the cell so as to be extended to one of the cells in contact therewith.

  The example of FIG. 1 is an example showing that the locus 401 handwritten on the input tablet 202 of the handwriting input unit 12 by the stylus pen 301 is displayed on the input display device 201 of the handwriting input unit 12. Furthermore, in the example of FIG. 1, since the locus of the stylus pen 301 is continuously detected from the normal input area 211 to the extended input area 221, the handwritten data processing apparatus 10 performs handwriting from the normal input area 211 to the extended input area 221. In this example, the locus 401 of the stylus pen 301 is extended and displayed (extension line 402). In this example, the handwritten data processing apparatus 10 performs linear interpolation or spline interpolation using a predetermined number (for example, four points) of the coordinate points of the trajectory collected immediately before, and the stylus pen is immediately before the stylus pen. The trajectory 401 is extended while calculating the coordinate points of the trajectory that should travel along the flow of movement, and the display portion 2014 is extended from cell C704 to cell C404 and displayed (extension line 402). Then, for example, the handwritten data processing device 10 creates stroke data from the cell C704 to the cell C404 and stores the stroke data in the storage unit (auxiliary storage unit 2015 described later).

  FIG. 2 is a functional block diagram showing a functional configuration of the handwritten data processing apparatus 10 according to an embodiment of the present invention. The handwritten data processing apparatus 10 includes a display unit 2014 as a first display unit, an input display unit 201 as a second display unit, a cell display configuration unit 11 as a cell display configuration unit, and a handwriting input unit. Handwriting input unit 12, input display unit 13 as an input display unit, input range configuration unit 14 as an input range configuration unit, normal cell association unit 15 as a normal cell association unit, and extended cell association Extended cell association unit 16 as means, data display creation unit 17 as data display creation means, time measurement unit 18 as time measurement means, correspondence cell movement unit 19 as correspondence cell movement means, and interruption time An interruption time measuring unit 20 as a measuring unit and an input ending unit 21 as an input ending unit are provided.

  The display unit 2014 displays the locus input by handwriting as described above in accordance with the cell resolution. The input display device 201 displays a locus input by handwriting.

  The cell display configuration unit 11 causes the display unit 2014 to configure a predetermined number of cells in a matrix and display an image for each configured cell. For example, the cell display configuration unit 11 configures the matrix cell 101 (15 × 25) in accordance with the resolution of the display unit 2014 (for example, 240 × 400), and the trajectory input by handwriting on the input display unit 13 In accordance with the resolution of the display unit 2014, it is displayed on the cell. The predetermined number of cells is variable depending on a set value for the number of cells.

  The handwriting input unit 12 includes an input display device 201 and an input tablet 202 that is disposed in front of the input display device 201 and has translucency. The input tablet 202 detects contact with the stylus pen 301 and outputs coordinate information indicating the position of the detected contact. The handwriting input unit 12 may be a touch panel in which a transparent touch pad is used for the input tablet 202 and a display device such as a liquid crystal display is integrally formed. The input tablet 202 may be a resistance pressure-sensitive method, a capacitance method, an electromagnetic induction method, or the like. The input tablet 202 and the display unit 2014 may have different resolutions. The stylus pen 301 is preferably a dedicated pen suitable for each method, but in the case of the resistance pressure-sensitive method, a general pen, a pencil, or the like may be used.

  The input display unit 13 causes the input display device 201 of the handwriting input unit 12 to display a locus handwritten on the input tablet 202 of the handwriting input unit 12 by the stylus pen 301. For example, the input display unit 13 receives the coordinate information of the locus handwritten by the stylus pen 301 from the input tablet 202 and causes the input display device 201 to display the coordinate information based on the received coordinate information. For example, the input display unit 13 receives coordinate information from the input tablet 202 that has detected contact with the stylus pen 301 and displays the locus of the stylus pen 301 on the input display device 201 based on the received coordinate information. The trajectory of the stylus pen 301 is created by continuing the display points of the input display device 201 corresponding to the received coordinate values with a curve (for example, a spline function).

  The input range configuration unit 14 has a normal input area 211 in which the locus of the stylus pen 301 can be input by hand on the handwriting input unit 12, and an extended input area 221 surrounded by the outer periphery of the normal input area 211. And configure. For example, the input range configuration unit 14 configures the handwriting input unit 12 and the input display device 201 as shown in FIG. The size of the normal input area 211 and the width of the extended input area 221 are variable depending on setting values.

  The normal cell associating unit 15 is configured such that the locus of the stylus pen 301 input to the normal input area 211 is the normal input area 211 and one cell among the plurality of cells configured by the cell display configuration unit 11. Correspond as shown in the cell. For example, the normal cell association unit 15 associates the trajectory of the stylus pen 301 input in the normal input area 211 so as to be displayed in the cell C704 as shown in FIG.

  The extended cell association unit 16 divides the extended input area 221 into predetermined sections, the positional relationship between one of the divided sections and the normal input area 211, and one corresponding to the normal input area 211. The one partition and the one cell in contact with each other are associated with each other such that the positional relationship between the cell in contact with the cell and the positional relationship between the one cell is the same. For example, as shown in FIG. 1, the extended cell association unit 16 divides the extended input area 221 into predetermined sections 221-1 to 221-4 and sections 221-A to 221-D. Then, the extended cell association unit 16 includes, for example, the positional relationship between the partition 221-1 and the normal input area 211 (the partition 221) among the partitioned partitions 221-1 to 221-4 and partitions 221-A to 221-D. −1 is the upper relationship with respect to the normal input area 211) and the positional relationship with the cell C704 among the cells C603 to C805 that are in contact with the cell C704 associated with the normal input area 211 by the normal cell association unit 15 The cell C604 having the same positional relationship (the cell C604 is an upper relationship with respect to the cell C704) is associated with the partition 221-1.

  The data display creation unit 17 displays the trajectory of the stylus pen 301 input to the normal input area 211 in accordance with the resolution of one cell associated by the normal cell association unit 15 and creates stroke data. . For example, as shown in FIG. 1, the data display creation unit 17 displays the trajectory of the stylus pen 301 input to the normal input area 211 in accordance with the resolution of the cell C 704 associated by the normal cell association unit 15. And create stroke data. The data display creating unit 17 then detects the stylus pen of the extended input area 221 when the locus of the stylus pen detected by the handwriting input unit 12 is continuously detected from the normal input area 211 to the extended input area 221. The locus of the stylus pen 301 handwritten from the normal input area 211 to the extended input area 221 is extended and displayed in the cell associated with the section where the pen 301 is stopped.

  Furthermore, the data display creation unit 17 includes an interruption time storage control unit 22 as interruption time storage control means, and a threshold optimization unit 23 as threshold optimization means. The interruption time storage control unit 22 stores the measured time in association with the stroke data every time the interruption time measurement unit 20 measures the time. The threshold optimization unit 23 calculates and optimizes the stroke threshold by statistical processing based on the time stored in association with the stroke data by the interruption time storage control unit 22. For example, the interruption time measuring unit 20 measures the time between the locus by the stylus pen 301 when handwritten (for example, the time for waiting for the next stroke for each stroke when inputting characters). Then, the interruption time storage control unit 22 stores the measured time in association with the stroke data (for example, refer to the stroke waiting time Ts in the stroke data in FIG. 4). Then, for example, the threshold value optimization unit 23 aggregates the time stored in association with the stroke data every time input of one cell is completed, and performs statistical processing. In the statistical processing, for example, an arithmetic average is performed except for a time longer than a certain value or a time less than a certain value, or a weighted average based on the length of stroke data is performed. The threshold optimization unit 23 further optimizes the calculated value (for example, a value smaller than the statistical value of the input waiting time Tg, twice the calculated value, etc.), and dynamically sets a stroke threshold that is regarded as the end of input. To decide.

  When the position of the stylus pen 301 detected by the handwriting input unit 12 is continuously detected from the normal input area 211 to the extended input area 221, the time measuring unit 18 is within the same section of the extended input area 221. Measure the stop time. For example, as shown in FIG. 1, the time measuring unit 18 expands when the position of the stylus pen 301 detected by the handwriting input unit 12 is continuously detected from the normal input area 211 to the extended input area 221. The time which has stopped in the same section 221-1 in the input area 221 is measured. When the time measured by the time measurement unit 18 is equal to or longer than a predetermined time (for example, 0.3 seconds depending on the set value), the data display creation unit 17 stops the stylus pen 301 in the extended input area 221. The trajectory of the stylus pen 301 handwritten from the normal input area 211 to the extended input area 221 is extended and displayed in the cell C603 associated with the section 221-1 that is being displayed. Then, the data display creating unit 17 creates the extended stroke data and stores it in the handwritten data DB 31 (see FIG. 4 described later).

  The corresponding cell moving unit 19 moves the association from one cell associated by the normal cell associating unit 15 to a cell different from the one cell. For example, when the corresponding cell moving unit 19 detects the contact of the stylus pen 301 in the section of the extended input area 221 in the neutral state, the corresponding cell moving unit 19 moves the correspondence between the cell and the normal input area 211 according to the touched section. . The corresponding cell moving unit 19 corresponds to the normal input area 211 when the section where the contact is detected is the upper section 221-1, the right section 221-2, the lower section 221-3, or the left section 221-4. The attachment is moved upward, rightward, downward or leftward, respectively. Further, the corresponding cell moving unit 19 is configured so that the cell in which the contact is detected is the upper left corner section 221-A, the upper right corner section 221-B, the lower right corner section 221-C, or the lower left corner section 221-D. The association with the input area 211 is moved in the upper left direction, the upper right direction, the lower right direction, or the lower left direction, respectively. Here, the neutral state is a state where the stylus pen 301 is not in contact with the normal input area 211 and the extended input area 221. When the input end unit 21 instructs the end of the input, the association between the cell and the normal input area 211 is moved according to the section of the extended input area 221 detected by the input end unit 21. Here, the predetermined cell is, for example, an adjacent right cell in the case of movement in the right direction. For example, in the case of the right end cell, the predetermined cell is the left end cell of the next row.

  Further, the corresponding cell moving unit 19 stores the direction of movement from one cell associated by the normal cell associating unit 15 each time the association is moved to a predetermined cell different from the one cell. It memorize | stores in 2012. Then, when the time measured by the interruption time measuring unit 20 is equal to or greater than the stroke threshold, the corresponding cell moving unit 19 stores the memory cell 2012 from one cell associated by the normal cell associating unit 15. The association is moved to a predetermined cell in the same direction as the movement direction. For example, the corresponding cell moving unit 19 stores, in the memory 2012, the right direction moved each time the association is moved from one cell associated by the normal cell associating unit 15 to the cell adjacent to the right. Then, the corresponding cell moving unit 19 regards the input as the end when the time measured by the interruption time measuring unit 20 is equal to or greater than the stroke threshold, and stores the right direction stored in the memory 2012 (that is, the same as the previous direction). The correspondence is moved to the adjacent cell in the direction.

  When the position of the stylus pen 301 detected by the handwriting input unit 12 is not detected, the interruption time measuring unit 20 measures the time that is not detected. Depending on the time measured by the interruption time measuring unit 20, the handwritten data processing device 10 can measure the waiting time between strokes and the waiting time for input from one cell to the next cell. .

  The input end unit 21 instructs the end of input. For example, when the input ending unit 21 detects the contact of the stylus pen 301 in the section of the extended input area 221 while the interruption time measuring unit 20 is measuring, the corresponding cell moving unit 19 To instruct. When contact with the stylus pen 301 in a specific section of the extended input area 221 (for example, the lower right corner section 221-C of the extended input area 221) is detected, the end of input in the cell may be instructed. . The handwritten data processing device 10 is associated by the normal cell association unit 15 when the time measured by the interruption time measurement unit 20 is equal to or greater than the stroke threshold or when the input end unit 21 instructs the end of input. The association is moved from the one cell to a predetermined cell different from the one cell.

  FIG. 3 is a block diagram showing a hardware configuration of the handwritten data processing apparatus 10 according to an embodiment of the present invention.

  As illustrated in FIG. 3, the handwritten data processing apparatus 10 includes a CPU (Central Processing Unit) 2011, a memory 2012, an operation unit 2013, a display unit 2014, an auxiliary storage unit 2015, an I / F unit 2040, and an input display unit 13. The handwriting input unit 12 connected by the line 2050 and connected to the input display unit 13 includes an input display device 201 and an input tablet 202.

  The CPU 2011 is a part that controls the handwritten data processing apparatus 10 in an integrated manner, and by reading and executing various programs stored in the memory 2012 as appropriate, the CPU 2011 cooperates with the above-described hardware and performs various functions according to the present invention. Is realized.

  The operation unit 2013 includes an operation button group for performing various settings and input operations, a determination operation button, and the like. Input information from the operation unit 2013 is processed under the control of the CPU 2011. The display unit 2014 includes an LCD (Liquid Crystal Display) and an organic EL (Electro Luminescence), and displays various types of information.

  The auxiliary storage unit 2015 is configured by a flash memory or the like, stores various programs for the handwritten data processing device 10 to function and programs for executing the functions of the present invention, and further stores various databases such as the handwritten data DB31. It is configurable.

  The I / F unit 2040 is an interface that connects the handwritten data processing device 10 to an auxiliary storage device for storing handwritten data and a peripheral device such as a communication device for connecting to a server.

  The input display unit 13 causes the input display device 201 of the handwriting input unit 12 to display a locus handwritten on the input tablet 202 of the handwriting input unit 12 by the stylus pen 301. The handwriting input unit 12 includes an input display device 201 and an input tablet 202 that is disposed in front of the input display device 201 and has translucency.

  The input display device 201 is configured by an LCD, an organic EL, or the like, and displays a locus input to the input tablet 202. The input tablet 202 is configured by a translucent tablet, a touch pad, or the like, detects contact of the stylus pen 301, and outputs coordinate information of the detected contact position.

  FIG. 4 is a diagram illustrating an example of stroke data of the handwritten data processing apparatus 10 according to an embodiment of the present invention. The stroke data includes, for example, cell information, input waiting time Tg, coordinate information, and stroke waiting time Ts.

  Cell information includes cell position information associated with the normal input area 211 (for example, cell position information configured in the display unit 2014, page information in the case of the electronic sheet 501 described in Embodiment 2 described later), and Position within the page).

  The input waiting time Tg is measured until the end of input in one cell is detected and input in the next cell is detected (for example, after handwriting of one character is finished and handwriting is started in the next cell). It was time. If the actually measured input waiting time Tg is longer than a predetermined input waiting time (for example, 1.618 times the average of Tg), the handwritten data processing apparatus 10 has finished inputting the predetermined input waiting time into this cell. Is the input waiting time Tg from the start of input to the next cell. The handwritten data processing apparatus 10 calculates the predetermined input waiting time by performing statistical processing such as averaging processing on the input waiting time Tg based on the stroke data stored in the handwritten data DB 31.

  The stroke waiting time Ts is a time measured from one stroke to the next stroke (for example, from the end of writing one stroke to the start of writing the next stroke). Then, the handwritten data processing device 10 performs statistical processing such as average processing on the stroke waiting time Ts based on the stroke data stored in the handwritten data DB 31. For example, the handwritten data processing device 10 monitors the end of input of one cell based on a value obtained by statistically processing the input waiting time Tg and a value obtained by statistically processing the stroke waiting time Ts for each input end of one cell. The stroke threshold (for example, a value larger than the value obtained by statistically processing Ts and smaller than the value obtained by statistically processing Tg) is dynamically determined. For example, when the user's handwriting speed is fast, the stroke threshold value is smaller. Thus, the handwritten data processing apparatus 10 can automatically determine the end of input in one cell in accordance with the user's handwriting speed.

  The coordinate information is coordinate information output from the input tablet 202. The handwritten data processing apparatus 10 samples the coordinate information output from the input tablet 202 at regular time intervals (for example, 0.1 seconds) from the contact of the stylus pen 301 to the release of the stylus pen 301 (from the pen down to the pen up). Then, coordinate information is extracted according to a predetermined condition. For example, when the handwritten data processing apparatus 10 determines that the data has the same point (for example, data within a predetermined range), the handwritten data processing apparatus 10 deletes the data having the same point. Further, the handwritten data processing device 10 uses the coordinate information of the latest coordinate points (for example, four points) collected in the normal input area 211 while the tip of the stylus pen 301 is stopped in the extended input area 221. Linear interpolation or spline interpolation is performed to automatically extend the trajectory to the adjacent cell. The handwritten data processing apparatus 10 uses coordinate information obtained by interpolation instead of sampling as coordinate information on the extension line. When the stylus pen 301 continues to stay in the extended input area 221, the handwritten data processing apparatus 10 extends the extended locus to the next new cell and measures the time for which the stylus pen 301 is stopped in the extended input area 221. When the measurement time is again longer than a predetermined time (for example, 0.3 seconds), the automatic extension of the locus point is resumed again. The coordinate information may include color information (for example, a specified color), a line type (for example, an interpolation type for a curve), and the like.

Then, the handwritten data processing apparatus 10 stores the movement direction in the memory 2012.

  In the normal mode, when the handwritten data processing apparatus 10 detects contact of the stylus pen 301 with the stroke erasing section 221-1-6, the stroke data touched with the stylus pen 301 after the detection is erased by the stroke erasing function. Note that the handwritten data processing apparatus 10 returns to the normal state when the contact of the stylus pen 301 is detected again in the stroke erasing section 221-1-6. For example, the stroke erasing function erases stroke data touched by the stylus pen 301 in units of one cell of the display unit 2014 (ie, one cell of the electronic sheet 501) associated with the normal input area 211.

  In the normal mode, when the handwritten data processing apparatus 10 detects contact of the stylus pen 301 with the page movement sections 221-3-1 to 221-3-4, the normal input area 211 and the display unit 2014 are displayed by the page movement function. The association between the display unit 2014 and the page of the electronic sheet 501 is moved according to the operation without changing the association with one cell. For example, the left page movement function assigned to the upward section 221-3-1 moves the association between the display unit 2014 and the page of the electronic sheet 501 upward. Similarly, the lower page moving function assigned to the lower section 221-3-2, the right page moving function assigned to the right section 221-3-3, or the left section 221-3-4.

When the handwritten data processing apparatus 10 detects the contact of the stylus pen 301 in a predetermined section (for example, the right section 221-2) of the extended input area 221, the handwritten data processing apparatus 10 responds to the normal input area 211 via one cell of the display unit 2014. A mark corresponding to the mark jump function is stored in a cell of the attached electronic sheet 501.

  In the page mode, the handwritten data processing apparatus 10 moves the association between the normal input area 211 and one cell of the display unit 2014 (that is, one page of the electronic sheet 501) according to the operation by the cell moving function. For example, the upper cell movement function assigned to the up arrow section 221-1-2 among the cell movement sections corresponds to the normal input area 211 and the cells constituting the display unit 2014 (that is, one page of the electronic sheet 501). Move the attachment upward by one. Similarly, the down cell moving function, the right cell moving function, or the left assigned respectively to the down arrow section 221-1-3, the right arrow section 221-1-4, or the left arrow section 221-1-5 among the cell moving sections. The cell movement function moves the association between the normal input area 211 and one cell of the display unit 2014 one by one downward, rightward, or leftward. Then, the handwritten data processing apparatus 10 stores the movement direction in the memory 2012.

  In the page mode, the handwritten data processing apparatus 10 touches the stylus pen 301 in units of one cell (that is, one page of the electronic sheet 501) associated with the normal input area 211 by the stroke erasing function. Delete the stroke data.

  In the page mode, the handwritten data processing apparatus 10 uses the page movement function to change the correspondence between the normal input area 211 and one cell of the display unit 2014 without changing the correspondence between the one cell of the display unit 2014 and the electronic sheet 501. The correspondence with the page is moved according to the operation. For example, the left page moving function assigned to the upper section 221-3-1 moves the association between one cell of the display unit 2014 and the page of the electronic sheet 501 upward. Similarly, the lower page moving function assigned to the lower section 221-3-2, the right page moving function assigned to the right section 221-3-3, or the left section 221-3-4. The left page movement function moves the correspondence between one cell of the display unit 2014 and the page of the electronic sheet 501 downward, right, or left, respectively.

  In the page mode, the handwritten data processing apparatus 10 receives a page input by a page jump function. Then, the handwritten data processing device 10 does not change the association with the one cell of the display unit 2014 associated with the normal input area 211, and the electronic sheet 501 with one cell (for example, the cell C101) of the display unit 2014. The association with the page is moved to the received page.

  In the page mode, the handwritten data processing device 10 associates a page including a cell marked on the electronic sheet 501 with one cell (for example, the cell C101) by the mark jump function, and displays the display unit. The one cell 2014 is associated with the normal input area 211.

  In the all-page mode, the handwritten data processing apparatus 10 moves the association between the normal input area 211 and one cell of the display unit 2014 (that is, one page of the electronic sheet 501) according to the operation by the cell moving function. . For example, the upper cell movement function assigned to the up arrow section 221-1-2 among the cell movement sections corresponds to the normal input area 211 and one cell of the display unit 2014 (that is, one page of the electronic sheet 501). Move the attachment upward by one. Similarly, the down cell moving function, the right cell moving function, or the left cell moving function respectively assigned to the down arrow section 221-1-3, the right arrow section 221-1-4, or the left arrow section 221-1-5 The association between the normal input area 211 and one cell of the display unit 2014 is moved one by one downward, rightward, or leftward. Then, the handwritten data processing apparatus 10 stores the movement direction in the memory 2012.

  In the all-page mode, the handwritten data processing apparatus 10 uses the page movement function to associate the normal input area 211 with one cell of the display unit 2014 (that is, one page of the electronic sheet 501) according to the operation. Move like the move function.

  In the all-page mode, the handwritten data processing apparatus 10 receives a page input by the page jump function. Then, the handwritten data processing apparatus 10 moves the association between the normal input area 211 and one cell of the display unit 2014 to the received page.

  In the all page mode, the handwritten data processing apparatus 10 associates one cell of the display unit 2014 corresponding to the page including the cell marked on the electronic sheet 501 with the normal input area 211 by the mark jump function.

  In the all page mode, the stroke erasing function and the intra-cell erasing function (EC) perform strokes according to operations in units of one cell of the display unit 2014 (ie, one page of the electronic sheet 501) associated with the normal input area 211. Erase the data. The page erase function (EP) erases the stroke data of all pages displayed on the display unit 2014.
