  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the upper left side, lower right side, upper side, lower side, upper right side, and lower left side in FIG. 1 are respectively defined as the left side, right side, front side, rear side, upper side, and lower side of the reader 2.

  The outline of the handwriting input system 1 will be described with reference to FIG. The handwriting input system 1 mainly includes a reading device 2, an electronic pen 3, and a smartphone 19. The reading device 2 is a thin and light handwriting input device. In the handwriting input system 1, the user writes a line drawing on the paper medium 100 attached to the reading device 2 using the electronic pen 3. The line drawing includes characters, numerical values, symbols, figures, and the like. The reading device 2 acquires the position of the electronic pen 3 in the writing process. The reading device 2 creates stroke data based on the acquired position. The stroke data includes at least a plurality of coordinate data indicating each of a plurality of positions on the line drawing written by the electronic pen 3. For this reason, each of the plurality of coordinate data indicates a locus of movement of the electronic pen 3 when a line drawing is written by the electronic pen 3. The reading device 2 can transmit the created stroke data to the smartphone 19. When the smartphone 19 receives the stroke data, the smartphone 19 displays an image corresponding to the received stroke data on the display 192. Thus, the user can visually recognize a line drawing having the same shape as the line drawing written on the paper medium 100 with the electronic pen 3 via the display 192. Further, the user can save stroke data indicating a line drawing written on the paper medium 100 with the electronic pen 3 in the reading device 2 and the smartphone 19.

  The reading device 2 has a rectangular thin plate shape. The reading device 2 includes a placement unit 2A on the front surface and an LED 5 on the upper end. A sensor substrate 7 (see FIG. 2), which will be described later, is disposed on the rear side of the mounting portion 2A. The paper medium 100 is detachably mounted on the placement unit 2A. The paper medium 100 includes a plurality of sheets 111 with upper end portions bound. The format indicating the layout of characters, line segments, etc. printed in advance on each of the plurality of sheets 111 may differ for each of the plurality of sheets 111. The paper medium 100 is mounted in a state in which the paper medium 100 is positioned on the placement portion 2A by a double-sided tape, an adhesive resin film, or the like. The user can use the electronic pen 3 to write a line drawing on the paper 111 arranged at the outermost part among the plurality of papers 111 of the paper medium 100. In addition, the user changes the page of the topmost sheet on which writing is to be performed with the electronic pen 3 among the plurality of sheets 111 to the next page by turning the topmost sheet. The plurality of sheets 111 of the paper medium 100 is not limited to the case where the upper end is bound, and any of the left end, the right end, and the lower end may be bound.

  The electronic pen 3 is a known electromagnetic induction type electronic pen, and mainly includes a cylindrical body 30, a core body 31, a coil 32, capacitors 33 and 35, a substrate 34, an ink storage unit 36, and a switch (not shown). . The cylindrical body 30 has a cylindrical shape, and houses a part of the core body 31, the coil 32, the capacitors 33 and 35, the substrate 34, and the ink storage unit 36 therein. The core body 31 is provided at the tip of the electronic pen 3. The core body 31 is urged toward the distal end side of the electronic pen 3 by an elastic member (not shown). The distal end portion of the core body 31 protrudes outside the cylindrical body 30. The rear end side of the core 31 is connected to an ink storage portion 36 that stores ink. The ink storage unit 36 supplies ink to the core body 31. When the user performs an operation of writing on the outermost sheet using the electronic pen 3, a line drawing is formed on the outermost sheet by the ink.

  The coil 32 is held between the core body 31 and the capacitor 33 while being wound around the ink storage portion 36. The capacitor 33 is fixed inside the electronic pen 3 by the substrate 34. A capacitor 35 is mounted on the substrate 34. The capacitors 33 and 35 are connected in parallel to the coil 32 and constitute a known resonance (tuning) circuit. An unillustrated switch is provided behind the core body 31. The switch is turned off when the core body 31 protrudes from the cylindrical body 30 and is turned on when the core body 31 enters the cylindrical body 30. When the switch is turned on, the coil 32 is turned on, and when the switch is turned off, the coil 32 is turned off. For this reason, when writing with the electronic pen 3 is not performed, the core body 31 protrudes from the cylindrical body 30, so that the switch is turned OFF and the coil 32 is in a non-conductive state. On the other hand, when writing with the electronic pen 3 is performed, the core body 31 enters the inside of the cylindrical body 30, so that the switch is turned on and the coil 32 is in a conductive state.

  The smartphone 19 includes a touch panel 191 and a display 192. The touch panel 191 is used for inputting various instructions. The display 192 can display an image corresponding to the image file. A general-purpose PC or a tablet PC may be used instead of the smartphone 19.

  The electrical configuration of the handwriting input system 1 will be described with reference to FIG. The electrical configuration of the reading device 2 will be described. The reading device 2 includes a main board 20, a sensor control board 28, a sensor board 7, an input unit 25, and an LED 5. The main board 20 includes a CPU 21, a RAM 22, a flash memory 23, and a wireless communication unit 24. The sensor control board 28 includes an ASIC 28A. The RAM 22, the flash memory 23, the wireless communication unit 24, the input unit 25, the LED 5, and the ASIC 28A are electrically connected to the CPU 21. The sensor substrate 7 is electrically connected to the ASIC 28A.

  The CPU 21 controls the reading device 2. The RAM 22 temporarily stores various data such as calculation data. The flash memory 23 stores a program that the CPU 21 executes to control the reading device 2. The flash memory 23 stores a format table. In the format table, the medium ID and the layout data are associated with each other. The medium ID is identification information indicating the type of the paper medium 100. The layout data is data that can specify the format of each of the plurality of sheets 111 of the paper medium 100 indicated by the corresponding medium ID for each page.

  Note that the program is stored in the flash memory 23 in advance when the reader 2 is shipped. Note that the program stored in the flash memory 23 may be rewritable after shipment. For example, the CPU 21 may receive the program via the wireless communication unit 24 and store it in the flash memory 23.

  The wireless communication unit 24 is a controller for executing short-range wireless communication with an external electronic device. The input unit 25 is a switch for inputting an instruction to the reading device 2. The ASIC 28 </ b> A detects coordinate data indicating the position of the electronic pen 3 when a writing operation by the electronic pen 3 is performed on the sensor substrate 7. On the sensor substrate 7, a plurality of elongated loop coils are arranged in each of the vertical direction and the horizontal direction.

  The operation principle of the reading device 2 will be described. The principle by which coordinate data is detected when a writing operation with the electronic pen 3 is performed on the sensor substrate 7 will be schematically described. The CPU 21 controls the ASIC 28 </ b> A to flow a specific frequency current (excitation current for excitation) one by one through the plurality of loop coils of the sensor substrate 7. As a result, a magnetic field is generated from each of the plurality of loop coils of the sensor substrate 7.

  In this state, it is assumed that, for example, the user performs an operation of writing a line drawing on the outermost sheet among the plurality of sheets 111 of the paper medium 100 mounted on the reading device 2 using the electronic pen 3. In this case, the electronic pen 3 is close to the sensor substrate 7. Further, when the core 31 of the electronic pen 3 enters the cylindrical body 30 in accordance with the writing operation, the switch is turned on and the coil 32 becomes conductive. For this reason, the resonance circuit of the electronic pen 3 resonates by electromagnetic induction and generates an induction magnetic field.

  Next, the CPU 21 controls the ASIC 28 </ b> A to stop the generation of the magnetic field from each of the plurality of loop coils of the sensor substrate 7. The loop coil of the sensor substrate 7 receives an induced magnetic field generated from the resonance circuit of the electronic pen 3. The CPU 21 controls the ASIC 28 </ b> A to detect signal currents (reception currents) flowing through the plurality of loop coils of the sensor substrate 7. The ASIC 28A executes this operation one by one for all of the plurality of loop coils. The ASIC 28A specifies the position of the loop coil when the received current is detected as coordinate data indicating the position of the electronic pen 3, and outputs the coordinate data to the CPU 21. When the coordinate data is output from the ASIC 28A, the CPU 21 has the electronic pen 3 approaching the sensor substrate 7 on the rear side of the placement unit 2A and the core body 31 has entered the cylindrical body 30. It is determined that a line drawing is written by the electronic pen 3 on the paper 111 of the paper medium 100 placed on the placement unit 2A.

  The electrical configuration of the smartphone 19 will be described. The smartphone 19 mainly includes a CPU 41, a RAM 42, a flash memory 43, a wireless communication unit 44, an input circuit 45, an output circuit 46, a touch panel 191, and a display 192. The CPU 41 controls the smartphone 19. The CPU 41 is electrically connected to the RAM 42, the flash memory 43, the wireless communication unit 44, the input circuit 45, and the output circuit 46.

  The RAM 42 stores various temporary data. The wireless communication unit 44 is a controller for executing short-range wireless communication with an external electronic device. The input circuit 45 performs control to send an instruction from the touch panel 191 to the CPU 41. The output circuit 46 performs control to display an image on the display 192 in accordance with an instruction from the CPU 41.

  The flash memory 43 stores a program executed by the CPU 41, a page storage area 134 (see FIG. 11), which will be described later, a correspondence table 135 (see FIG. 12), and the like. The smartphone 19 includes a medium reading device (for example, a memory card slot) not shown. The smartphone 19 can read a program stored in a storage medium (for example, a memory card) with a medium reader and install it in the flash memory 43. Alternatively, the program may be received from an external device (not shown) connected to the smartphone 19 or a network and installed in the flash memory 43.

  With reference to FIG. 3, an outline and a specific usage example of the paper 111 of the paper medium 100 will be described. The left side, right side, upper side, and lower side of FIG. 3 are defined as the left side, right side, upper side, and lower side of the sheet 111, respectively. The paper 111 is a paper for writing a line drawing. The sheet 111 includes a plurality of sheets 111 (for example, sheets 111A, 111B, 111C...). The medium IDs of the paper 111A, the paper 111B, and the paper 111C are the same. FIG. 3 shows one sheet of paper 111 (paper 111 </ b> A) of the paper medium 100 loaded in the reading device 2.

  The paper 111 has a writing area 50, a normal check box 55A, and a postscript check box 55B. The writing area 50 includes a memo area 51 and a page box 52. The memo area 51 is an area for the user to write a memo or the like. For example, the user writes the line drawing 51 </ b> A with the electronic pen 3 in the memo area 51 of the paper 111 </ b> A. The line drawing 51A indicates “information A”.

  The page box 52 is printed at the upper right corner of the writing area 50. A page box 52 indicates an area for writing the page number of the paper 111. The page number is a number for identifying one or a plurality of sheets 111 among the sheets 111 from the other sheets 111. In the present embodiment, the page number is one or two digits. The page box 52 includes a first page box 52A and a second page box 52B. The second page box 52B is provided on the left side of the first page box 52A. The shapes of the first page box 52A and the second page box 52B are rectangular single lines. The first page box 52A is an area for writing the first digit of the page number of the paper 111. The second page box 52B is an area for writing the second digit of the page number of the paper 111. The user writes the page number of the paper 111 with the electronic pen 3 in the page box 52 of the paper 111. For example, when the page number of the paper 111A is “26”, the user writes “2” in the second page box 52B of the paper 111A and “6” in the first page box 52A.

  The normal check box 55A is printed at the lower right corner of the paper 111. The postscript check box 55B is printed on the left side of the normal check box 55A on the paper 111. The shapes of the normal check box 55A and the additional check box 55B are rectangular. The normal check box 55 </ b> A and the additional writing check box 55 </ b> B indicate areas where the user writes a line drawing in order to confirm the line drawing written in the writing area 50. For example, when the user finishes writing on the paper 111A, the user writes the line drawing in either the normal check box 55A or the additional writing check box 55B in order to notify the reading device 2 that the line drawing written in the writing area 50 has been confirmed. To do.

  When the CPU 21 of the reading device 2 determines that a line drawing has been written in the normal check box 55 </ b> A of the paper 111 with the electronic pen 3, the CPU 21 creates stroke data corresponding to the line drawing written in the writing area 50. If the CPU 21 determines that a line drawing has been written with the electronic pen 3 in the additional writing check box 55 </ b> B of the paper 111, the CPU 21 creates additional data and stroke data corresponding to the line drawing written in the writing area 50. The additional writing instruction is an instruction for causing the CPU 41 of the smartphone 19 to create additional writing described later.

  The CPU 41 can acquire stroke data from the reading device 2. In this case, the user operates the touch panel 191 to transmit a data request instruction to the reading device 2. The data request instruction is an instruction for causing the CPU 21 of the reading device 2 to transmit stroke data. When receiving a data request instruction from the smartphone 19, the CPU 21 transmits the stroke data and the medium ID to the smartphone 19. Note that if an additional write instruction has been created, the CPU 21 also transmits an additional write instruction to the smartphone 19. The CPU 41 of the smartphone 19 receives the stroke data and the medium ID transmitted from the reading device 2. Note that when the additional writing instruction is transmitted, the CPU 41 also receives the additional writing instruction from the reading device 2. CPU41 specifies as a line drawing based on stroke data. CPU41 specifies a page number based on the specified line drawing.

  The CPU 41 creates an image file indicating the memo area 51 including the specified line drawing for each page number of the same medium ID. The image file is a data file that shows a line drawing as a digital image. Examples of digital images include vector images and raster images. Examples of the image file include a JPEG file, a GIF file, a PNG file, and a BMP file. The CPU 41 stores the created image file in the flash memory 43 in association with the stroke data, the medium ID, and the page number.

  The user can display the selection table 700 shown in FIG. 6 on the display 192 by operating the touch panel 191. As shown in FIG. 6, the selection table 700 displays the created image file in a form associated with the medium ID and page number. In this case, the image files are displayed in descending order of page numbers for each medium ID. Note that the user can also display, for example, image files in ascending order of page numbers by operating the touch panel 191.

  The user can display an image indicated by the selected image file on the display 192 by operating the touch panel 191 and selecting an image file from the selection table 700. In this case, since the image files are arranged in the order of page numbers, the user can easily search for an image file having a desired page number. The CPU 41 causes the display 192 to display an image indicated by the selected image file. Thereby, the user can visually recognize an image corresponding to the line drawing written on the paper 111 on the smartphone 19.

  With reference to FIG. 7, a method for specifying the page number will be described with a specific example. The page numbers shown in FIG. 7 all correspond to the same medium ID. The CPU 41 specifies the page number of the paper 111 by specifying the first digit and the second digit of the page number. The CPU 41 overwrites the specified page number for each medium ID and stores it in the flash memory 43. Thereby, CPU41 can refer to the page number specified last time as needed, when specifying the page number explained below.

  First, the CPU 41 determines whether or not a line drawing has been written in the first page box 52A. When a line drawing is written in the first page box 52A, the CPU 41 determines whether a line drawing is written in the second page box 52B. When a line drawing is written in both the first page box 52A and the second page box 52B, the first and second digits of the page number are written in the first page box 52A and the second page box 52B, respectively. The page number is specified by specifying the number specified from each line drawing. For example, as shown in FIG. 7, when “6” and “2” are written in the first page box 52A and the second page box 52B, respectively, the page number is “regardless of the page number specified last time”. 26 ".

  When the line drawing is written in the first page box 52A and the line drawing is not written in the second page box 52B, the CPU 41 refers to the flash memory 43, and the page number corresponding to the same medium ID is the last time. It is determined whether the specified page number is 2 digits. That is, it is determined whether the second digit of the page number corresponding to the medium ID of the paper 111 whose page number is to be specified is stored in the flash memory 43. When the page number corresponding to the same medium ID and the page number specified last time is two digits, the CPU 41 sets the second digit of the page number to 2 of the page number specified last time corresponding to the same medium ID. Specify the number indicated by the digit. For example, as shown in FIG. 7, when the previously specified page number is “26”, “7” is written in the first page box 52A, and no line drawing is written in the second page box 52B. In this case, the CPU 41 specifies the page number as “27”. Therefore, when the second digit of the page number of the paper 111 used last time matches the second digit of the page number of the paper 111 used this time, the user writes only the first digit of the page number in the first page box 52A. There is no need to write the second digit of the page number in the second page box 52B.

  When the page number corresponding to the same medium ID and the page number specified last time is one digit, or when the page number has not been specified for the same medium ID, the CPU 41 Is specified as “0”. The CPU 41 specifies the first digit of the page number as a number specified from the line drawing written in the first page box 52A. That is, when the second digit of the page number corresponding to the same medium ID is not stored in the flash memory 43, the page number is specified as one digit. For example, as shown in FIG. 7, when the page number specified last time is “6” or the current page number is specified for the first time, “7” is written in the first page box 52A, and the second When a line drawing is not written in the page box 52B, the CPU 41 specifies the page number as “7”.

  When the line drawing is not written in the first page box 52A, the CPU 41 determines whether the page number corresponding to the same medium ID and the previously specified page number is stored in the flash memory 43. When the previously specified page number corresponding to the same medium ID is stored in the flash memory 43, the CPU 41 specifies the page number corresponding to the same medium ID and the previously specified page number. To do. For example, if the previously specified page number is “26” and no line drawing is written in the first page box 52A, the CPU 41 specifies the page number as “26”. For example, as shown in FIG. 7, the user may write a line drawing on two sheets of paper 111, such as when a line drawing cannot be completed on one sheet of paper 111. In this case, the user can easily manage the two sheets 111 by combining them into one page. When the user manages the paper 111 used this time with the same page number as the paper 111 used last time, the user need not write the page number in the page box 52.

  As shown in FIG. 7, when a line drawing is not written in the first page box 52A and the page number is not yet specified for the same medium ID, the CPU 41 sets the page number to “ 1 ”. Therefore, the user does not need to write a line drawing in the page box 52 of the first page of the paper 111.

  With reference to FIG. 3 to FIG. 5, how the CPU 41 creates an image file will be described. The CPU 41 creates an image file by any one of new creation, additional creation, and additional writing creation described below. The new creation will be described with reference to FIG. For example, when creating an image file of the paper 111A, the CPU 41 determines whether the specified page number is already stored in the flash memory 43 in the same medium ID as the paper 111A. For example, when 26 pages are not yet stored in the flash memory 43 on the same medium ID as the paper 111A, a new image file is created. In the selection table 700 (see FIG. 6), when the user operates the touch panel 191 to select a newly created image file, a new image 90A is displayed on the display 192. The new image 90A shows the memo area 51 including the line drawing 51A. When creating a new image file, the user writes a page number that is not yet stored in the smartphone 19 in the page box 52, and then writes a line drawing in the normal check box 55A or the additional check box 55B.

  The additional creation will be described with reference to FIGS. 3 and 4. As shown in FIG. 4, the sheet 111 </ b> B includes a line drawing 51 </ b> B written in the memo area 51. The line drawing 51B indicates “information B”. The page number “26” of the paper 111B is the same as the page number of the paper 111A. A line drawing is written in the normal check box 55A. For example, it is assumed that the smartphone 19 receives the stroke data corresponding to the paper 111B after receiving the stroke data corresponding to the paper 111A. In this case, the page number “26” specified based on the stroke data corresponding to the sheet 111B is already stored in the flash memory 43 as the page number “26” of the sheet 111A.

  If the specified page number is already stored in the flash memory 43 and no additional write instruction has been received, the CPU 41 creates an additional image file. In the selection table 700 (see FIG. 6), when the user operates the touch panel 191 to select an additionally created image file, a combined image 90B is displayed on the display 192. The combined image 90B shows the memo area 51 of the paper 111A including the line drawing 51A and the memo area 51 of the paper 111B including the line drawing 51B. When creating an additional image file, the user writes the page number already stored in the smartphone 19 in the page box 52, and then writes the line drawing in the normal check box 55A.

The CPU 41 connects the plurality of positions indicated by the plurality of coordinate data corresponding to the extracted line segment data with straight lines in the order of the times indicated by the associated plurality of time data. The CPU 41 combines the line segments obtained one by one for each line segment data, and identifies it as a line drawing.

  The CPU 41 determines whether a line drawing has been written in the first page box 52A based on a plurality of coordinate data included in the stroke data stored in the RAM 42 (S62). Specifically, when at least one of the plurality of coordinate data indicates a position in the first page area, the CPU 41 determines that a line drawing has been written in the first page box 52A (S62: YES). On the other hand, when all of the plurality of coordinate data indicate positions outside the first page area, the CPU 41 determines that no line drawing is written in the first page box 52A (S62: NO).

  When the CPU 41 determines that a line drawing has been written in the first page box 52A (S62: YES), the line drawing is written in the second page box 52B based on a plurality of coordinate data included in the stroke data stored in the RAM 42 in S54. It is determined whether it has not been done (S63). Specifically, when at least one of the plurality of coordinate data indicates a position in the second page area, the CPU 41 determines that a line drawing has been written in the second page box 52B (S63: NO). On the other hand, when all of the plurality of coordinate data indicate positions outside the second page area, the CPU 41 determines that no line drawing is written in the second page box 52B (S63: YES).

  When the CPU 41 determines that the line drawing has been written in the second page box 52B (S63: NO), it specifies the page number as follows.

The first page line drawing data and the second page line drawing data are line drawing data corresponding to coordinate data indicating positions in the first page area and the second page area, respectively. The CPU 41 identifies the first digit and the second digit of the page number as numbers indicated by the first page line drawing data and the second page line drawing data, respectively. Thereby, the page number of the stroke data received in S54 is specified. CPU41 advances a process to S76.

  If the CPU 41 determines in S63 that the line drawing is not written in the second page box 52B (S63: YES), the target page data indicating the 2-digit page number is stored in the page storage area 134 (see FIG. 11). It is determined whether it has been performed (S66). In the page storage area 134, page data is stored in association with the medium ID in S76 described later.

  When the CPU 41 determines that target page data indicating a two-digit page number is stored in the page storage area 134 (S66: YES), the CPU 41 specifies the page number as follows. The CPU 41 identifies the first digit and the second digit of the page number as the number indicated by the first page line drawing data and the second digit of the page number indicated by the target page data, respectively (S67, S68). Thereby, the page number of the stroke data received in S54 is specified. CPU41 advances a process to S76.

  When the CPU 41 determines that the target page data indicating the two-digit page number is not stored in the page storage area 134 (S66: NO), it specifies the page number as follows. The CPU 41 specifies the first digit and the second digit of the page number as the number indicated by the first page line drawing data and “0”, respectively (S69, S70). Thereby, the page number of the stroke data received in S54 is specified. CPU41 advances a process to S76.

  If the CPU 41 determines in S62 that no line drawing is written in the first page box 52A (S62: NO), it determines whether the target page data is stored in the page storage area 134 (S71). When the CPU 41 determines that the target page data is stored in the page storage area 134 (S71: YES), the CPU 41 specifies the page number as follows. The CPU 41 identifies the first and second digits of the page number as the first and second digits of the page number indicated by the target page data determined to be stored in S71, respectively (S72, S73). . That is, the page number of the stroke data received in S54 is specified to be the same as the page number indicated by the target page data determined to be stored in S71. CPU41 advances a process to S76.

  When the CPU 41 determines that the target page data is not stored in the page storage area 134 (S71: NO), it specifies the page number as follows. The CPU 41 identifies the first and second digits of the page number as “1” and “0”, respectively (S74, S75). That is, the paper 111 is specified as the first page. CPU41 advances a process to S76.

  In S76, the CPU 41 stores page data indicating the page number specified in S64 and S65, S67 and S68, S69 and S70, S72 and S73, or S74 and S75 in the RAM 42, and stores the page data in association with the medium ID. Store in the area 134 (S76). When the target page data is already stored in the page storage area 134, the page data indicating the specified page number is overwritten and stored on the target page data already stored. As a result, the page storage area 134 stores only one page data indicating the previously specified page number as the page data corresponding to one ID. The CPU 41 ends the page number specifying process, and returns the process to the second main process (see FIG. 9).

  As shown in FIG. 9, after completing the page number specifying process (S55), the CPU 41 associates the received medium ID with the page data stored in the RAM 42 and stores them in the correspondence table 135 (see FIG. 12). (S81).

  If the CPU 41 determines that the received medium ID and the page data stored in the RAM 42 are associated with each other and are not stored in the correspondence table 135 (S81: NO), the image file is based on the line drawing data stored in the RAM 42. Is newly created (S82). The CPU 41 associates the received medium ID, the newly created image file, the stroke data stored in the RAM 42, and the page data stored in the RAM 42 and stores them in the correspondence table 135 (S82). The CPU 41 returns the process to S52.

  When the CPU 41 determines that the received medium ID and the page data stored in the RAM 42 have already been associated with each other and stored in the correspondence table 135 (S81: YES), the CPU 41 determines whether an additional writing instruction has been received (S81: YES). S83). When the CPU 41 determines that the additional writing instruction has not been received (S83: NO), the line drawing data stored in the RAM 42, the stroke data stored in the correspondence table 135 corresponding to the received medium ID and the specified page number, Based on the above, an image file is additionally created (S84). The CPU 41 associates the received medium ID, the additionally created image file, the stroke data stored in the RAM 42, and the page data stored in the RAM 42 and stores them in the correspondence table 135 (S84). The CPU 41 returns the process to S52.

  If the CPU 41 determines that an additional writing instruction has been received (S83: YES), the CPU 41 is based on the line drawing data stored in the RAM 42 and the stroke data stored in the correspondence table 135 corresponding to the received medium ID and the specified page number. Then, an image file is additionally created (S85). The CPU 41 associates the received medium ID, the additionally created image file, the stroke data stored in the RAM 42, and the page data stored in the RAM 42 and stores them in the correspondence table 135 (S85). The CPU 41 returns the process to S52.

  If the CPU 41 determines that the operation for selecting the button (a) is not detected via the touch panel 191 in the process of S52 (S52: YES), the operation for selecting the button (b) is performed by the touch panel. It is determined whether it is detected via 191 (S91). If the CPU 41 determines that the operation of selecting the button (b) has not been detected via the touch panel 191 (S91: NO), the process returns to S52.

  When the CPU 41 determines that the operation of selecting the button (b) has been detected via the touch panel 191 (S91: YES), the CPU 41 displays the selection table 700 (see FIG. 6) on the display 192 (S92). The selection table 700 includes image files and page numbers. In the selection table 700, image files are arranged in descending order based on page numbers.

  The CPU 41 determines whether an operation for selecting an image file has been detected via the touch panel 191 (S93). The user can select an image file included in the selection table 700 via the touch panel 191. If the CPU 41 determines that an operation for selecting an image file has not been detected via the touch panel 191 (S93: NO), the process returns to S52.

  When the CPU 41 detects an operation for selecting an image file via the touch panel 191 (S93: YES), the CPU 41 displays an image on the display 192 based on the selected image file (S94). The CPU 41 returns the process to S52.

  As described above, the CPU 41 of the smartphone 19 specifies the page number of the received stroke data based on the first page line drawing data and the second page line drawing data specified from the coordinate data included in the stroke data received in S54. To do. The CPU 41 stores the received stroke data in the correspondence table 135 of the flash memory 43 in association with each specified page number. For example, the user may write the same page number in the page box 52 of each paper 111 when writing related contents divided into a plurality of times. In this case, the CPU 41 can store a plurality of stroke data having the same page number in the correspondence table 135 in association with each other. Accordingly, since the smartphone 19 can manage a plurality of stroke data for each page number, the smartphone 19 can easily manage the stroke data.

  When the CPU 41 determines that the received stroke data does not include coordinate data indicating the position in the first page area, the CPU 41 identifies the target page data as the page number of the received stroke data. Thereby, for example, when the user divides the stroke data into a plurality of times and continuously stores them in association, there is no need to write the page number. Therefore, the CPU 41 can save the user from having to write the page number when the stroke data is stored in the correspondence table 135 in association with a plurality of times.

  When the CPU 41 determines that the received stroke data does not include the coordinate data indicating the position in the second page area, the second digit of the page number indicated by the target page data is 2 of the page number of the received stroke data. Specify the digit. Thus, for example, when the second digit of the page number of the paper 111 to be used is the same as the second digit of the page number of the paper 111 used last time, the user need not write the second digit of the page number. Therefore, when the second digit of the page number is the same as the previous time, the smartphone 19 can save the user from having to write the second digit of the page number.

  The CPU 41 can synthesize and create the received stroke data for each specified page number. For example, the user may synthesize and store new stroke data with previously stored stroke data. In this case, when the user writes the same page number as the page number of the previously stored stroke data, the CPU 41 additionally creates an image file based on the previously stored stroke data and the received stroke data. Therefore, the smartphone 19 can easily add and create an image file simply by writing the same page number.

  The CPU 41 determines whether an additional writing instruction has been accepted. When the CPU 41 receives an additional writing instruction, the CPU 41 additionally writes an image file for each page number based on the previously stored stroke data and the received stroke data. Therefore, when the CPU 41 accepts an additional writing instruction, the CPU 41 can additionally write an image file based on stroke data having the same page number. When the user causes the CPU 41 to execute the additional writing creation, the user writes a line drawing in the additional writing check box 55B. The smartphone 19 can easily create an additional image file simply by writing a line drawing in the additional recording check box 55B.

  The CPU 41 stores the page number in the correspondence table 135 of the flash memory 43 in association with the stroke data. Thereby, the CPU 41 can arrange the stored stroke data in the ascending order or descending order of the page numbers. For example, a user can manage stroke data arranged according to a predetermined rule more easily than stroke data arranged randomly. Therefore, the CPU 41 can easily manage the stroke data.

  The CPU 41 displays the image file created based on the stroke file on the display unit in the ascending order or descending order of the page numbers. For example, it is easier for a user to search for an image file that is arranged and displayed according to a predetermined rule than an image file that is arranged and displayed at random. Therefore, the CPU 41 can improve the searchability of the image file.

For example, in the above embodiment, the program stored in the flash memory 43 of the smartphone 19 may be stored in the flash memory 23 of the reading device 2. In this case, the CPU 21 of the reading device 2 may execute the second main process. In the above embodiment, the CPU 41 creates an image file for each page number, but may create an additional image file for each medium ID. In this case, the additionally created image file indicates an image in which images indicating the memo area 51 of each sheet 111 on which a line drawing is written are arranged in the order of page numbers. In the above embodiment, the image file shows the memo area 51, but it may show the writing area 50. That is, the image file may further indicate a line drawing written in the page box 52. In the above embodiment, the page number is 1 digit or 2 digits, but may be 3 digits or more. In this case, the page box 52 may further include a page box indicating an area for writing each digit of the page number on the left side of the second page box 52B. In this case, the CPU 41 may execute the process executed for the second digit of the page number also for the third and subsequent digits of the page number. The page number may be a single digit. The page box 52 may not include the second page box 52B, and two or more digits may be written in the first page box 52A. In this case, the CPU 41 may determine whether a line drawing has been written in the page box 52 in S62. When the CPU 41 determines that the line drawing has been written, the CPU 41 may specify the page number based on the written line drawing. CPU41 does not need to perform S71-S75. In this case, when the CPU 41 determines that no line drawing is written in the page box 52, the CPU 41 may store the stroke data without the page number in the flash memory 43, for example.

  In the said embodiment, although CPU41 of the smart phone 19 receives stroke data from the reader 2, the acquisition method of stroke data is not limited to this. For example, the CPU 41 may acquire stroke data from an image captured by a camera. The second main process may be executed by a CPU mounted on the camera. The smartphone 19 may be equipped with a camera.

  In the above embodiment, the CPU 21 does not have to execute the processes of S12, S17, and S18 in the first main process. That is, the additional recording instruction may not be stored in the flash memory 23. In this case, in the process of S83, if the CPU 41 determines that the line drawing specified in S61 shows a predetermined shape, the CPU 41 determines that an additional write instruction has been received, and executes the process of S85 to additionally write an image file. Good. If the CPU 41 determines in the process of S83 that the line drawing specified in S61 does not show a predetermined shape, the CPU 41 may execute the process of S84 to additionally create an image file. Data indicating the predetermined shape may be stored in the flash memory 43 in advance.

  The sheet 112 and the predetermined shape used in the above case will be described with reference to FIG. 13A and 13B show the lower right corner of the paper 112, respectively. The components corresponding to those of the paper 111 are denoted by the same reference numerals and description thereof is omitted. The sheet 112 includes a specific check box 55C instead of the normal check box 55A and the additional check box 55B of the sheet 111 of the above embodiment. The specific check box 55C is printed on the lower right corner of the paper 112. The specific check box 55C has a rectangular shape. The specific check box 55C indicates an area in which the user writes a line drawing in order to confirm the line drawing written in the writing area 50.

  For example, as shown in FIG. 13A, when a line drawing showing a line extending obliquely upward to the right is written in the specific check box 55C, the CPU 41 may determine that the specified line drawing shows a predetermined shape. . In this case, the CPU 41 stores the received stroke data in the RAM 42 in association with the additional writing instruction. As illustrated in FIG. 13B, when a line drawing indicating a line extending obliquely downward to the right is written in the specific check box 55C, the CPU 41 may determine that the specified line drawing does not indicate a predetermined shape. . In this case, the CPU 41 stores the created stroke data in the flash memory 43 without associating it with the additional write instruction. The predetermined shape may be a number, an alphabetic character, a symbol, or the like. If the CPU 21 determines that the specified line drawing shows a predetermined shape instead of the CPU 41, an additional write instruction may be stored in the RAM 22. In this case, the CPU 21 may specify a line drawing in advance based on the line segment data stored in the second area of the RAM 22.

  In the above case, the CPU 41 determines whether an additional writing instruction has been accepted based on whether the specified line drawing shows a predetermined shape. Therefore, since the writing area 50 does not need to include two areas, that is, an area for receiving an additional writing instruction and an area for not receiving an additional writing instruction, the smartphone 19 suppresses the proportion of the writing area 50 occupied by the area for the additional writing instruction. it can.

  Further, when the paper 112 is used, the CPU 41 may store the received stroke data in the RAM 42 in association with the additional writing instruction when detecting that the line drawing has been written in the specific check box 55C. You may memorize | store in RAM42, without matching with an additional writing instruction | indication. Whether stroke data created when a line drawing is written in the specific check box 55C is stored in the RAM 42 in association with the additional writing instruction may be set in advance. In this case, the CPU 41 does not have to execute S83. In the handwriting input system 1, when a line drawing is written in the specific check box 55C by the reading device 2 or the smartphone 19, it is determined whether or not the received stroke data is stored in the RAM 42 in association with the additional writing instruction. The user may be able to set in advance. Further, these processes may be executed by the CPU 21 of the reading device 2.

  In the above embodiment, instead of the CPU 21 of the reading device 2 executing S2 and S3, the CPU 41 of the smartphone 19 may execute the medium ID specifying process. In this case, the sheet 113 is used. The sheet 113 will be described with reference to FIG. The sheet 113 has an ID box 53. The ID box 53 is printed on the left side of the page box 52 in the writing area 50. The ID box 53 indicates an area for writing the medium ID. In this modification, the medium ID is a one-digit or two-digit alphabetic character. The medium ID may be one digit or three digits or more. The medium ID is not limited to English characters, and may be a number, a symbol, or a combination thereof.

  The ID box 53 includes a first ID box 53A and a second ID box 53B. The second ID box 53B is provided on the left side of the first ID box 53A. The shapes of the first ID box 53A and the second ID box 53B are rectangular single lines. First ID box 53A is an area for writing the first digit of the medium ID of paper 113. The second ID box 53B is an area for writing a second digit number in the medium ID of the paper 113. The user writes the medium ID of the sheet 113 with the electronic pen 3 in the page box 52 of the sheet 113. For example, when the medium ID of the sheet 113 is “AB”, the user writes “A” in the second ID box 53B of the sheet 113 and writes “B” in the first ID box 53A. The area on the front surface of the reading device 2 corresponding to the rectangular area constituting the first ID box 53A is referred to as a first ID area. The area on the front surface of the reading device 2 corresponding to the rectangular area constituting the second ID box 53B is referred to as a second ID area.

  The medium ID specifying process will be described with reference to FIG. The medium ID specifying process is executed before the page number specifying process (S55) when the CPU 41 receives stroke data or the like in the process of S54. The CPU 41 specifies a written character string based on the line segment data included in the stroke data stored in the RAM 42 (S101). The CPU 41 stores line drawing data indicating the specified character string in the RAM 42 (S101).

  The CPU 41 determines whether a line drawing has been written in the first ID box 53A based on a plurality of coordinate data included in the stroke data stored in the RAM 42 (S102). Specifically, the CPU 41 determines that a line drawing has been written in the first ID box 53A when at least one of the plurality of coordinate data indicates a position in the first ID area (S102: YES). On the other hand, when all of the plurality of coordinate data indicate positions outside the first ID area, the CPU 41 determines that no line drawing is written in the first ID box 53A (S102: NO).

  When the CPU 41 determines that a line drawing has been written in the first ID box 53A (S102: YES), the line drawing is written in the second ID box 53B based on a plurality of coordinate data included in the stroke data stored in the RAM 42 in S54. It is determined whether it has not been done (S103). Specifically, when at least one of the plurality of coordinate data indicates a position in the second ID area, the CPU 41 determines that a line drawing has been written in the second ID box 53B (S103: NO). On the other hand, if all of the plurality of coordinate data indicate positions outside the second ID area, the CPU 41 determines that no line drawing is written in the second ID box 53B (S103: YES).

  When the CPU 41 determines that a line drawing has been written in the second ID box 53B (S103: NO), it specifies the medium ID as follows. The CPU 41 identifies the first digit and the second digit of the medium ID as English letters or “0” written in the first ID box 53A and the second ID box 53B, respectively (S104, S105). Specifically, the CPU 41 specifies the first ID line drawing data and the second ID line drawing data from the line drawing data stored in the RAM 42, respectively. The first ID line drawing data and the second ID line drawing data are line drawing data corresponding to coordinate data indicating positions in the first ID area and the second ID area, respectively. The CPU 41 identifies the first digit and the second digit of the medium ID as the alphabet indicated by the first ID line drawing data and the alphabet indicated by the second ID line drawing data, respectively, or “0”. Thereby, the medium ID of the stroke data received in S54 is specified. CPU41 advances a process to S116.

  If the CPU 41 determines in S103 that no line drawing is written in the second ID box 53B (S103: YES), the medium ID stored in the ID storage area (not shown) of the flash memory 43 is two digits. Is determined (S66). In the ID storage area of the flash memory 43, the medium ID is overwritten and stored in S116 described later. That is, only the medium ID of the stroke data received last time is stored in the ID storage area of the flash memory 43.

  When the CPU 41 determines that a two-digit medium ID is stored in the ID storage area of the flash memory 43 (S106: YES), the CPU 41 specifies the medium ID as follows. The CPU 41 identifies the first digit and the second digit of the medium ID as the alphabet indicated by the first ID line drawing data and the second digit of the medium ID stored in the ID storage area (S107, S108). Thereby, the medium ID of the stroke data received in S54 is specified. CPU41 advances a process to S116.

  When the CPU 41 determines that the two-digit medium ID is not stored in the ID storage area of the flash memory 43 (S106: NO), it specifies the medium ID as follows. The CPU 41 identifies the first digit and the second digit of the medium ID as an alphabetic character indicated by the first ID line drawing data and “0”, respectively (S109, S110). Thereby, the medium ID of the stroke data received in S54 is specified. CPU41 advances a process to S116.

  If the CPU 41 determines in S102 that no line drawing is written in the first ID box 53A (S102: NO), it determines whether the medium ID is stored in the ID storage area of the flash memory 43 (S111). When the CPU 41 determines that the medium ID is stored in the ID storage area of the flash memory 43 (S111: YES), the CPU 41 specifies the medium ID as follows. The CPU 41 specifies the first digit and the second digit of the medium ID as the first digit and the second digit of the medium ID stored in the ID storage area of the flash memory 43, respectively (S112, S113). That is, the medium ID of the stroke data received in S54 is specified to be the same as the medium ID stored in the ID storage area of the flash memory 43. CPU41 advances a process to S116.

  When the CPU 41 determines that the medium ID is not stored in the ID storage area of the flash memory 43 (S111: NO), the CPU 41 specifies the medium ID as follows. The CPU 41 identifies the first digit and the second digit of the medium ID as “A” and “0”, respectively (S114, S115). CPU41 advances a process to S116.

  In S116, the CPU 41 stores the medium ID specified in S104 and S105, S107 and S108, S109 and S110, S112 and S113, or S114 and S115 in the RAM 42 and overwrites the ID in the ID storage area of the flash memory 43 ( S116). When the medium ID is already stored in the ID storage area of the flash memory 43, the specified medium ID is overwritten on the already stored medium ID and stored. Thereby, only one medium ID specified last time is stored in the ID storage area of the flash memory 43. The CPU 41 ends the medium ID specifying process and returns the process to the second main process (see FIG. 9). After completing the medium ID specifying process, the CPU 41 executes a page number specifying process (S55). Note that the CPU 41 associates the identified medium ID, the created image file, the stroke data stored in the RAM 42, and the page data stored in the RAM 42 with each other in the correspondence table 135 in the processing of S82, S84, and S85. Store.

  According to the above configuration, the CPU 41 specifies the medium ID based on the first ID line drawing data and the second ID line drawing data included in the received stroke data. The CPU 41 stores the received stroke data in the correspondence table 135 in association with each specified medium ID. Therefore, since the CPU 41 can manage the stored stroke data for each medium ID, the stroke data can be easily managed.

  When the CPU 41 determines that the line drawing is not written in the first ID box 53A and determines that the medium ID is stored in the ID storage area of the flash memory 43, the CPU 41 sets the medium ID of the stroke data to the flash memory 43. And the medium ID stored in the ID storage area. When the user continuously uses the same paper medium 100, the user only writes the medium ID on the first sheet 113, and does not need to write the medium ID on the second and subsequent sheets 113. Accordingly, the smartphone 19 can save the user from having to write the medium ID when the same paper medium 100 is continuously used.

  In the above modification, the first ID area and the second ID area correspond to the “specific area” of the present invention. The coordinate data indicating the position in the first ID area and the second ID area corresponds to “specific coordinate data” of the present invention. The medium ID corresponds to “specific data” of the present invention. The processes of S102 and S103 in FIG. 15 correspond to the “fourth determination step” of the present invention. The processes of S104 and S105 in FIG. 15 correspond to the “sixth specific step” of the present invention.
