Description

  The present invention relates to an electronic pen, a data editing method, and a data editing program for writing on paper.

  2. Description of the Related Art Conventionally, there are electronic pens that can write on dedicated paper on which dots are printed, read a dot pattern at the written position, and output the data as data.

  As this type of electronic pen, when a sentence is edited on a notebook, the contents are also edited on data at the same time (see Patent Document 1). With this electronic pen, the portion surrounded by “◯” moves to the designated location during editing.

  Moreover, what can express the operation | movement which cuts a page on data and pastes it on arbitrary places is known (refer patent document 2).

JP 2005-293461 A JP 2007-58653 A

  However, in the above-described conventional electronic pen, in order to move the content written on the paper surface to another page or another area, it is not shown that the content is pasted on the paper surface. However, this pasting and editing work was not reflected on the data.

  For this reason, when it is desired to reflect the work performed on the paper on the data, it is necessary to perform the same paste editing on the data of the PC (computer) separately from the work of the paste editing on the paper. Convenience was not good.

  Even when the paper is folded, the folding edit is not reflected in the data. Furthermore, even if a part of the paper is cut out and deleted, similarly, the deletion edit is not reflected on the data.

  The present invention has been made in view of the above-described conventional circumstances, and when an editing operation such as pasting, bending, or cutting is performed on a paper surface, the electronic contents that can reflect the edited contents in data An object is to provide a pen, a data editing method, and a data editing program.

  The electronic pen according to the present invention is an electronic pen for performing description on a sheet, and includes a coordinate detection unit that detects coordinates from dots of the sheet, and a first detected continuously in time by the coordinate detection unit. A coordinate position determination unit for determining whether or not the second coordinate and the second coordinate are discontinuous coordinates, a detection time at which the first coordinate is detected by the coordinate detection unit, and the first It is determined by the detection time determination unit that determines whether or not the detection time that is the detection time at which the coordinates of 2 are within a predetermined time and the coordinate position determination unit is discontinuous coordinates. And an editing processing unit that performs an editing process when the detection time determining unit determines that the detection time is within a predetermined time.

  According to this configuration, when it is determined that the coordinates are discontinuous and the detection time is determined to be within a predetermined time, the editing process on the data is performed. As a result, when an editing operation such as pasting, bending, or cutting is performed on the paper, the edited content can be reflected in the data.

  Further, the data editing method of the present invention is a data editing method executed by an electronic pen for writing on a sheet, wherein a coordinate detection step for detecting coordinates from dots on the sheet and a time detection in the coordinate detection step A coordinate position determination step for determining whether or not the first coordinate and the second coordinate detected consecutively are discontinuous coordinates, and the first coordinate in the coordinate detection step A detection time determination step for determining whether or not a detection time that is a time between the detection time at which the second coordinate is detected and the detection time at which the second coordinate is detected is within a predetermined time; and the coordinate position determination step. An edit processing step for performing an edit process when it is determined that the coordinates are discontinuous and the detection time is determined to be within a predetermined time in the detection time determination step.

  According to this method, when it is determined that the coordinates are discontinuous and the detection time is determined to be within a predetermined time, the editing process on the data is performed. As a result, when an editing operation such as pasting, bending, or cutting is performed on the paper, the edited content can be reflected in the data.

  The data editing program of the present invention is a program for causing a computer to execute each step of the data editing method.

  According to this program, when it is determined that the coordinates are discontinuous and the detection time is determined to be within a predetermined time, an editing process on the data is performed. As a result, when an editing operation such as pasting, bending, or cutting is performed on the paper, the edited content can be reflected in the data.

  According to the present invention, when an editing operation such as pasting, bending, and cutting is performed on a paper surface, the editing content can be reflected in data.

  Hereinafter, an electronic pen, a data editing method, and a data editing program according to an embodiment of the present invention will be described with reference to the drawings. The electronic pen of this embodiment is applied to a handwriting input system or the like.

(First embodiment)
FIG. 1 is a diagram showing a configuration example of a handwriting input system 1 using an electronic pen 5 according to the first embodiment of the present invention. The handwriting input system 1 includes an electronic pen 5, special paper 30 and a host computer 50.

  The electronic pen 5 includes a pen unit 11, a control unit 10, a writing pressure sensor 12, a camera (dot detection unit) 13, a memory (storage unit) 14, a data communication unit 17, and an external output unit 18. The pen unit 11 has an ink cartridge 11a (see FIG. 2) like a normal pen, and can write characters on the dedicated paper 30 with ink.

  The writing pressure sensor 12 detects the writing pressure of the pen unit 11 that increases when the user presses the electronic pen 5 against the paper surface. When the detected writing pressure exceeds a threshold value, the electronic pen 5 is turned on. .

  The camera (dot detection unit) 13 photographs a dot pattern printed on the paper surface when the pen pressure sensor 12 is turned on by the pressure from the paper surface.

  The control unit 10 includes a known CPU, ROM, RAM, and the like, and controls the entire electronic pen 5. The control unit 10 includes a coordinate detection unit 21, a coordinate change detection unit 22, and an editing execution unit 23. The coordinate detection unit 21 detects coordinates representing the position on the surface of the dedicated paper 30 from the dot pattern photographed by the camera 13. The coordinate change detection unit 22 detects discontinuous coordinates from the change in coordinates, and detects, for example, page switching of the dedicated paper 30. Even when page switching does not occur, that is, when editing is performed by cutting a part of one page and pasting it to another part of the same page, discontinuous coordinates are detected in the same manner. Therefore, page switching is an example when discontinuous coordinates are detected. The editing execution unit 23 performs editing such as pasting. Note that the functions of the coordinate detection unit 21, the coordinate change detection unit 22, and the edit execution unit 23 are realized by the CPU in the control unit 10 executing a program stored in the ROM.

  The memory 14 records the page switching position detected by the coordinate change detection unit 22 along with the coordinates detected by the coordinate detection unit 21. In the memory 14, a table 14 b that associates dot patterns with the position coordinates of the dedicated paper 30 is registered. The memory 14 is provided with a timer 14 a managed by the control unit 10, and the time counted by the timer 14 a is stored in a predetermined area of the memory 14.

  The data communication unit 17 performs wireless communication such as Bluetooth (registered trademark) and infrared communication with the host computer 50. The external output unit 18 outputs data to a card-type memory or the like that is detachably connected.

  FIG. 2A is an external view example of the electronic pen 5 described on the dedicated paper 30, and FIG. 2B is a diagram illustrating an example of a paper surface of the dedicated paper 30 described by the electronic pen 5. As described above, the electronic pen 5 can be held by a user and written on the dedicated paper 30 with ink as in a normal pen.

  A dot pattern that can be photographed by the camera 13 attached in the vicinity of the pen tip of the electronic pen 5 is printed on the surface of the dedicated paper 30. That is, the dedicated paper 30 is obtained by printing this dot pattern on the mount.

  When the camera 13 shoots the description position of the electronic pen 5, for example, the size of 1 mm × 1 mm is set as a shooting range, and the dot pattern 31 included therein is shot (see the enlarged portion 30 a in the drawing). The table 14b registered in the memory 14 associates the captured dot pattern with the position coordinates of the dedicated paper 30. The camera 13 may be equipped with a light emitting unit such as an LED to illuminate the shooting range.

  When the photographed dot pattern matches the dot pattern registered in the table 14b in the memory 14, the position coordinate is specified and recorded in the memory 14 as coordinate data. Since the technique for photographing the dot pattern printed on the dedicated paper and specifying the position coordinates is a known technique, a detailed description thereof will be omitted, and only a brief description will be given here.

  By moving the electronic pen 5 in contact with the special paper 30, the user writes characters or the like on the special paper 30 with ink that comes out of the pen tip. At the same time, the position coordinates specified by the dot pattern of the description position photographed by the camera 13 are recorded in the memory 14 in time series, and the description position on the dedicated paper 30 is specified. In the present embodiment, the camera 13 shoots, for example, 100 times per second, and the position coordinates are recorded in time series. Hereinafter, simply “dot” refers to a dot pattern whose position coordinates can be specified. The dot pattern is usually determined by the arrangement of a predetermined number or more (for example, 16) of dot groups, but the number can be reduced by changing the shape of the dots themselves, and at least one or more. Determined by the dots.

  Further, in the present embodiment, the description position is photographed by the camera 13 and its coordinate data (electronic data) is obtained. At the same time, the time data at the time of photographing is also obtained by the timer 14 a managed by the control unit 10. The

  On the other hand, the host computer 50 includes a computer body incorporating a well-known CPU, ROM, RAM, etc., input devices such as a mouse and a keyboard, a display panel, a printer, an external storage device, etc. A wireless communication unit 55 that transmits and receives data is included. When the host computer 50 receives the electronic data transmitted from the electronic pen 5, the host computer 50 recognizes the handwriting from the electronic data and acquires data such as characters, numbers, and symbols.

An example of the editing operation of the handwriting input system 1 having the above configuration will be shown.
Here, a case where pasting, corner bending (dog year), and deletion are performed as editing for a note that is an example of the dedicated paper 30 will be described. Further, when the editing for the notebook is compared with the editing for the electronic data, the electronic data (hereinafter simply referred to as data) on the PC (computer) refers to data recorded in the memory 14 of the electronic pen 5. Shall.

  FIGS. 3A and 3B are diagrams showing examples of paste editing on a notebook and data editing on a PC. As shown in FIG. 3A, the user first cuts out a portion 41 surrounding the character string “Kakikukeko” written on page Z, and cuts this cut-out portion 41 into “123456” written on page A. Is pasted on the portion 44 surrounding the numeral string. Then, the user draws straight lines 42 with the electronic pen 5 at the four corners of the pasted rectangular portion 41. In the page Z, a hole 43 is formed as a cut mark.

  When the user performs such a paper editing operation, as shown in FIG. 3B, the numeric string data 77 of “123456” described in page A of data 70 is described in page Z on the PC. It is overwritten by the character string data 78 of “Kakikukeko” (see dotted line frame g). Here, since the character string data 78 of “Kakikukeko” described in the original page Z remains, copy editing has been performed, but it may be deleted. In this case, moving editing is performed. .

  FIGS. 4A and 4B are diagrams showing examples of pasting and editing with sticky notes on a notebook and data editing on a PC. Note that the notebook, the sticky note paper 60 for pasting, and the sticky note paper 61 are all examples of the dedicated paper 30 having a dot pattern.

  As shown in FIG. 4A, the user peels off the sticky note 61 on which “Sashisuseso” is written from the sticky note paper 60 for pasting, and the portion 44 surrounding the number string “123456” written on the page A is displayed. Paste on top. As in FIG. 3, the user draws straight lines 62 with the electronic pen 5 at the four corners of the attached sticky note.

  When the user performs such a paper editing operation, as shown in FIG. 4B, the following data editing is performed on the PC. That is, the number string data 77 of “123456” described in page A of the data 70 is overwritten by the character string data 85 of “Sashisuseso” described in the tag of the sticky note data 80 for pasting (dotted line frame h reference). Here, moving editing is shown, and the character string data 85 of the sticky note in which “Sashisuseso” is written is deleted from the data of the sticky note paper 80 for pasting.

  FIGS. 5A and 5B are diagrams for explaining a detection example of paste editing. As shown in FIG. 5A, straight lines 42 and 62 are drawn from the page A (note) on which the square paper is pasted to the other page (part 41, tag 61) that is the pasted paper. FIG. 5B shows an enlarged portion 30b near the straight lines 42 and 62 drawn in the upper left corner.

  In this way, when drawing a straight line from page A toward another page, the dot pattern (dot arrangement) changes suddenly from the middle, and the electronic pen 5 has another page pasted. Recognize that. The same applies to a case where a portion in the same page is cut and pasted.

  In the paste editing process on the PC, the control unit 10 uses the editing execution unit 23 to use two regions surrounded by a plurality of discontinuous coordinates, and a line passing the discontinuous coordinates is inside the region. The information of the first region extending toward is duplicated in the second region where the line passing through the discontinuous coordinates extends toward the outside of the region. Thereby, the pasting operation on the paper surface can be reflected on the PC data.

  In other words, in the example of FIG. 3, the information of the first area (character string data 78 of “Kakikukeko” on page Z) is converted into the number string data 77 of “123456” described on page A. Are replicated in the area). In the example of FIG. 4, the information of the first area (the area of the sticky note 80 for sticking) (the character string data 85 of the sticky note in which “Sashisuseso” is written) is described in the second area (page A). (The area of the numeric string data 77 of “123456”). By applying markings that draw straight lines at the four corners of other pages, the pasting source and pasting destination can be clearly separated.

  FIG. 6 is a flowchart showing an example of the paste editing operation procedure. This operation program is stored in the ROM in the control unit 10 and is executed by the CPU in the control unit 10. Here, a case where a paste editing operation is performed when page switching is recognized at four points is shown.

  The control unit 10 uses the coordinate detection unit 21 to detect coordinates from the dot pattern photographed by the camera 13 (step S1). The control unit 10 determines whether or not the page change for four times is detected by the coordinate change detection unit 22 (step S2). In the process of step S2, it is determined whether or not the first coordinate and the second coordinate detected continuously in time by the coordinate detection unit 21 are discontinuous coordinates. An example of a function as a coordinate position determination unit). Then, positionally discontinuous coordinates are determined four times, that is, four page changes are detected.

  When the page switching for four times is detected, the control unit 10 determines whether or not the switching time of each page is less than a threshold value (for example, 0.5 seconds) (step S3). That is, it is determined whether or not the detection time, which is the time between the detection time when the first coordinate is detected by the coordinate detection unit 21 and the detection time when the second coordinate is detected, is within a predetermined time (threshold). Is performed (an example of a function as a detection time determination unit). This threshold value is set to a value that can distinguish between a longer time required for switching the page of the note and a shorter time required for moving to the paper attached to the page.

  If all four times are less than the threshold, the control unit 10 determines that pasting with paper has been performed, and the editing execution unit 23 performs pasting editing (step S4). As described above, when it is determined that the coordinates are discontinuous and the detection time is determined to be within a predetermined time, editing processing is performed (an example of a function as an editing processing unit). Details of this paste editing will be described later. Thereafter, the control unit 10 ends this operation.

  On the other hand, when it is more than the threshold value at least once in step S3, the control unit 10 recognizes that it is a normal input operation (step S5), and ends this operation. On the other hand, if the page switching for four times is not detected in step S2, the control unit 10 recognizes that it is a normal input operation (step S6) and ends this operation.

  FIG. 7 is a flowchart showing an example of the paste editing execution procedure in step S4. The control unit 10 acquires first coordinates indicating page switching from the first straight line drawn by the electronic pen 5, and records the first coordinates in the memory 14 (step S11).

  Similarly, the control unit 10 acquires second, third, and fourth coordinates indicating page switching and records them in the memory 14 (steps S12, S13, and S14).

  The control unit 10 connects the first coordinate to the fourth coordinate with, for example, a straight line, and determines a region (editing area) in which pasting editing has been performed (step S15).

  The control unit 10 executes editing on the memory 14, that is, performs an operation of overwriting the data in the editing area of page A stored in the memory 14 with the data of other pages (step S16). At this time, when data on other pages is maintained without being erased, copy editing is performed, and when data is erased, moving editing is performed. Thereafter, the control unit 10 ends this operation and returns to the original processing.

  As described above, according to the electronic pen 5 of the present embodiment, the editing operation for pasting performed on the paper surface can be distinguished from the normal input and reflected in the data on the PC. Therefore, the editing process is facilitated.

  In the above-described embodiment, the case where the pasting paper is a square has been described. However, pasting and editing can be similarly performed on a pasting paper having an arbitrary shape.

  When specifying the shape of the affixed paper, when marking is performed by sequentially drawing a straight line at each corner, the marking may be performed so that the last corner is different from the other corners. FIGS. 8A and 8B are diagrams illustrating an example of marking that represents an end point when specifying the shape of the attached paper. As shown in FIG. 8 (A), the end point is represented by drawing a double line 48 at the last corner of the attached paper.

  As shown in FIG. 8B, a pentagonal attached sheet is specified by marking the end point at the fifth corner.

  FIG. 9 is a flowchart showing an example of the pasting editing execution procedure when the pasting paper is a polygon. This operation program is stored in the ROM in the control unit 10 and is executed by the CPU in the control unit 10.

  The control unit 10 uses the coordinate detection unit 21 to detect coordinates from the dot pattern photographed by the camera 13 (step S21). The control unit 10 determines whether or not the page change is detected by the coordinate change detection unit 22 (step S22). In the process of step S22, the coordinate change detection unit 22 determines whether or not the first coordinate and the second coordinate detected continuously in time are discontinuous coordinates. . When the coordinates are discontinuous in position, a page change is detected.

  When the page change is not detected, the control unit 10 records the input coordinates in the memory 14 (step S23), and returns to the process of step S21.

  On the other hand, when a page change is detected, the control unit 10 determines whether or not the page change time is less than a threshold (for example, 0.5 seconds) (step S24). That is, it is determined whether or not the detection time, which is the time between the detection time when the first coordinate is detected by the coordinate detection unit 21 and the detection time when the second coordinate is detected, is within a predetermined time (threshold). To be done. This threshold value is set to a value that makes it possible to distinguish between a longer time required for switching the notebook page and a shorter time required for moving to the paper attached to the page.

  If it is equal to or greater than the threshold, the control unit 10 returns to the process of step S21. On the other hand, when the page switching time is less than the threshold value in step S24, the control unit 10 records the page switching coordinates by linking with the count number n indicating the number of page switching so far (step S25). That is, a value obtained by adding 1 to the count number n so far is set as a new count number n ′, and page switching coordinates are recorded in association with the count number n ′ (= n + 1).

  The controller 10 determines whether or not the count number n ′ is 3 or more (determined three or more times) (step S26). If the value is less than 3, it cannot be specified as a polygon, and the control unit 10 returns to the process of step S21. As a case where it is determined three or more times in step S26, for example, as shown in FIG.

  On the other hand, if the count number n ′ is 3 or more in step S26, the control unit 10 determines whether the coordinates of the count number n ′ and the coordinates of the count number n′−1 are substantially the same, that is, FIG. It is determined whether or not the two lines shown in (A) have been drawn (step S27). In this way, it is determined whether or not the last detected coordinate and the coordinate detected immediately before are substantially the same.

  If not substantially the same, the control unit 10 returns to the process of step S21. On the other hand, when the coordinates of the count number n ′ and the coordinates of the count number n′−1 are substantially the same, the control unit 10 determines the order of the count numbers 1, 2,..., N′−1, n ′. The coordinates are connected by a line to determine the pasting area (step S28). Thus, by explicitly indicating the last coordinates, the pasting area can be easily determined.

  Subsequently, the control unit 10 clears the count number n to 0 (step S29). Subsequently, the control unit 10 performs paste editing by the editing execution unit 23 (step S30). As described above, when it is determined that the coordinates are discontinuous and the detection time is determined to be within a predetermined time, an editing process is performed.

  The control unit 10 records the data after the paste editing process in the memory 14 (step S31). Thereafter, the control unit 10 ends this operation.

  Here, the case where editing is performed by pasting cut paper on another page of paper has been shown, but in this case, although it corresponds to moving editing on the paper side, the original data is left (maintained) on the PC side. ) Or deletion, it can be moved or copied.

  The user may change the marking method between moving and copying in order to clearly indicate that the editing is copy editing. FIG. 10 is a diagram showing marking when copying is performed as paste editing. When the first straight lines 42 and 62 are drawn so as to straddle the corner of the pasted paper, and then the second cross line 49 that is substantially orthogonal to the straight lines is drawn, the control unit 10 23, the copy editing may be determined and the original data may be maintained. On the other hand, when the cross line 49 is absent, the control unit 10 may determine that the editing execution unit 23 is moving editing and delete the original data. As a result, copy editing and move editing can be explicitly separated.

  As described above, the control unit 10 performs the paste editing process when it is determined that the coordinates are discontinuous three or more times. As a result, the paste editing process can be performed based on the operation on the paper, distinguishing from other editing processes.

  Further, the control unit 10 may perform the paste editing process when it is determined that the coordinates are discontinuous four times and when the detection time is determined to be within a predetermined time each time. Thereby, it is possible to specify the pasting area without performing the marking detection indicating the end point, and perform the pasting editing process.

  Further, the control unit 10 determines that the coordinates are discontinuous three or more times, determines that the detection time is within a predetermined time each time, and the coordinates detected last and the coordinates detected immediately before that. The paste editing process may be performed when and are substantially the same coordinates. Thereby, it is possible to perform paste editing processing by using various polygons as the paste area, not limited to the quadrangle.

  In addition, when there is a line that is substantially orthogonal to the line passing through the discontinuous coordinates by the editing execution unit 23, the control unit 10 maintains the information of the first region and is substantially orthogonal to the line that passes through the discontinuous coordinates. If there is no line to be deleted, the information in the first area is deleted. Thereby, it can be specified based on the user's intention whether or not to leave the copy source data.

(Second Embodiment)
In the first embodiment, the case where paste editing is performed is shown, but in the second embodiment, the case where editing is performed by bending one corner of a note (dog year) is shown.

  The electronic pen 5 according to the second embodiment of the present invention has substantially the same configuration as the electronic pen 5 according to the first embodiment. The same components as those of the electronic pen 5 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIGS. 11A and 11B are diagrams showing examples of dog-ear editing on a notebook and data editing on a PC in the present embodiment. As shown in FIGS. 11A and 11B, when the user bends the corner of the notebook and draws a line 64 from the front page to the back page, marking is performed on the PC (electronic pen 5). The dog year editing process is also performed on the data.

  In this dog-ear editing process, the control unit 10 causes the editing execution unit 23 to perform processing on pages where discontinuous coordinates do not exist at the end of the page among pages where discontinuous coordinates are continuous (for example, front and back). For example, a process of adding a check mark or the like as the predetermined information is performed on the front side page corresponding to the paper whose corners are bent. Further, the control unit 10 performs processing such as bending the corners of the front page and hiding the data hidden in the folded back page. This makes it possible to mark important pages.

  FIG. 12 is a flowchart showing an example of the dog-ear editing operation procedure. This operation program is stored in the ROM in the control unit 10 and is executed by the CPU in the control unit 10. The same step numbers are assigned to the same step processes as those in FIG. 6 of the first embodiment.

  The control unit 10 uses the coordinate detection unit 21 to detect coordinates from the dot pattern photographed by the camera 13 (step S1). The control unit 10 determines whether or not a continuous page change is detected by the coordinate change detection unit 22 (step S2A). That is, when coordinates that extend from the front side page to the back side page are detected as continuous pages, it is determined that dock-ear editing has been performed with one corner of the note folded.

  When the continuous page switching is detected, the control unit 10 determines whether or not the page switching time is less than a threshold (for example, 0.5 seconds) (step S3).

  When it is less than the threshold value, the control unit 10 determines that corner bending (dog year) has been performed, and executes the dog year editing by the editing execution unit 23 (step S4A). Thereafter, the control unit 10 ends this operation.

  On the other hand, when it is more than a threshold value at Step S3, control part 10 recognizes that it is normal input operation (Step S5), and ends this operation. On the other hand, if page switching is not detected in step S2, the control unit 10 recognizes that the operation is a normal input operation (step S6), and ends this operation.

  As described above, when it is determined that the discontinuous coordinates are the coordinates of the continuous pages and the detection time is determined to be within the predetermined range, the control unit 10 performs the dog-ear editing process. As a result, when dock year editing is performed on the paper, it is possible to reflect this editing content in the data, distinguishing from normal input. Also, it is possible to easily mark important pages on the data as if using a normal note.

(Third embodiment)
The third embodiment shows a case where deletion editing is performed.
The electronic pen 5 of the present embodiment has substantially the same configuration as the electronic pen 5 of the first embodiment. The same components as those of the electronic pen 5 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIGS. 13A and 13B are diagrams illustrating an example of marking when performing deletion editing in the present embodiment. As shown in FIG. 13A, when the (X-1) th page of paper is deleted on the dedicated paper 30, leaving the left end portion, the Xth page of paper appears on the right side. When deletion editing is performed with paper, the user moves the pen tip of the electronic pen 5 from the left X-1 page of paper to the right X page of paper, as shown in FIG. Then, the marking 47 for returning to the X-1 page paper is performed again. That is, the page switching coordinates are detected once by the operation of the U character once the page is switched to return to the original page again. The marking is not limited to the U-shape, and may be performed so as to have another shape such as an O-shape. When such a delete / edit operation is detected, the data is deleted.

  FIG. 14 is a flowchart showing an example of the deletion edit execution procedure. This operation program is stored in the ROM in the control unit 10 and is executed by the CPU in the control unit 10. The same step numbers are assigned to the same step processes as those in FIG. 9 of the first embodiment.

  The control unit 10 uses the coordinate detection unit 21 to detect coordinates from the dot pattern photographed by the camera 13 (step S21). The control unit 10 determines whether or not the page change is detected by the coordinate change detection unit 22 (step S22).

  When the page change is not detected, the control unit 10 records the input coordinates in the memory 14 (step S23), and returns to the process of step S21.

  On the other hand, when a page change is detected, the control unit 10 determines whether or not the page change time is less than a threshold (for example, 0.5 seconds) (step S24).

  If it is equal to or greater than the threshold, the control unit 10 returns to the process of step S21. On the other hand, when the page switching time is less than the threshold value in step S24, the control unit 10 records the page switching coordinates by linking with the count number n indicating the number of page switching so far (step S25). That is, a value obtained by adding 1 to the count number n so far is set as a new count number n ′, and page switching coordinates are recorded in association with the count number n ′ (= n + 1).

  The control unit 10 determines whether the count number n ′ is a value of 2, that is, whether or not the discontinuous coordinates are determined twice (step S26A). When the value is not 2, the control unit 10 returns to the process of step S21.

  On the other hand, when the count number n ′ in step S26A is 2, the control unit 10 determines whether or not a U-shaped operation that spans multiple pages is detected (step S27A).

  When the operation of the U-character extending over a plurality of pages is not detected, the control unit 10 recognizes that the input is a normal input (step S28A) and returns to the process of step S21. On the other hand, when the operation of the U-character extending over a plurality of pages is detected, the control unit 10 clears the count number n to 0 (step S29). The control unit 10 performs a deletion editing process using the editing execution unit 23 (step S30A). In this deletion editing, the data of the first page is deleted. Thereby, the deletion work on the paper can be reflected on the data. Then, the control unit 10 records the data after the deletion editing process in the memory 14 (step S31). Thereafter, the control unit 10 ends this operation.

  As described above, the control unit 10 performs the deletion editing process when it is determined twice that the coordinates are discontinuous. Thereby, based on the operation on the paper, the deletion editing process can be performed in distinction from the other editing processes.

  In addition, the control unit 10 determines that the coordinates are discontinuous twice, and a line passing through the first discontinuous coordinates extends from the first page to the second page, and the second discontinuous coordinates. If it is detected that it extends through the coordinates and returns to the first page, a deletion editing process is performed. As a result, when the cut (delete) editing is performed on the paper, the edited content can be reflected in the data. In addition, the page can be easily deleted and edited by operating the U character.

  The present invention is not limited to the configuration of the above-described embodiment, and any configuration can be used as long as the functions shown in the claims or the functions of the configuration of the present embodiment can be achieved. Is also applicable.

  For example, in the above embodiment, the electronic data is data stored in the memory 14 of the electronic pen 5, but may be data transmitted from the electronic pen 5 and stored in the host computer 50. In this case, an editing instruction for data is transmitted from the electronic pen 5 to the host computer 50, and the host computer 50 edits the data according to the editing instruction. In this case, data on the PC (computer) indicates data stored in the host computer 50.

  The present invention is also applicable to a program that supplies the electronic pen 5 with a program that realizes the functions of the above-described embodiments via a network or various storage media, and that is read and executed by a computer in the electronic pen 5. .

  INDUSTRIAL APPLICABILITY The present invention is useful for an electronic pen, a data editing method, a data editing program, and the like that can reflect the edited contents in data when editing operations such as pasting, bending, and cutting are performed on the paper. .
