The RAM 22, flash ROM 23, and wireless communication unit 24 are electrically connected to the CPU 21. The CPU 21 controls the reading device 2. The RAM 22 temporarily stores various data such as calculation data.

  The flash ROM 23 stores various programs that the CPU 21 executes to control the reading device 2. The flash ROM 23 stores stroke data indicating the locus of the electronic pen 3. The flash ROM 23 stores a position specifying table and character data described later. The flash ROM 23 stores information related to the reading device 2 (hereinafter referred to as internal information). The internal information includes, for example, firmware version information of the reading device 2, the number of times stroke data is saved, the number of times the power is turned on, the number of times an error has occurred, the type, date, time, and various settings of the paper medium 100 loaded in the reading device 2. Including values. The flash ROM 23 stores internal information as numerical data. The wireless communication unit 24 is a controller for executing short-range wireless communication with an external electronic device.

  The input unit 25 is electrically connected to the CPU 21. The input unit 25 includes a switch for inputting an instruction to the reading device 2. Specifically, the input unit 25 includes a power switch and a special mode switch. The power switch is a switch for inputting a power ON / OFF instruction to the reading device 2. The special mode switch is a switch for inputting a specific processing start instruction or the like to the reading device 2.

  On the sensor boards 7L and 7R, a large number of elongated loop coils are arranged in each of the left-right direction (X-axis direction) and the vertical direction (Y-axis direction). The sensor board 7L is electrically connected to the ASIC 28A of the sensor control board 28. The ASIC 28A detects the position of the electronic pen 3 as coordinate information when the writing operation by the electronic pen 3 is performed on the sensor substrate 7L. The sensor board 7R is electrically connected to the ASIC 29A of the sensor control board 29. The ASIC 29A detects the position of the electronic pen 3 as coordinate information when the writing operation by the electronic pen 3 is performed on the sensor substrate 7R. Of the ASICs 28A and 29A, the master-side ASIC 28A is directly connected to the CPU 21, and the slave-side ASIC 29A is connected to the CPU 21 via the ASIC 28A.

  Each of the sensor substrates 7L and 7R includes a detection region. The detection area is an area corresponding to a portion where the loop coils are arranged in each of the sensor substrates 7L and 7R. Therefore, when the paper medium 100 is mounted on the reading device 2 at an appropriate position, the paper medium 100 is placed on the detection area. The detection region of the sensor substrate 7L and the detection region of the sensor substrate 7R have the same configuration. Therefore, in the following description, only the detection region of the sensor substrate 7L will be described, and the description of the detection region of the sensor substrate 7R will be omitted.

  The principle of acquiring line drawing data will be schematically described. The CPU 21 controls the ASICs 28A and 29A to flow a current (excitation transmission current) having a specific frequency to each of the loop coils of the sensor boards 7L and 7R. Thereby, a magnetic field is generated from each loop coil of the sensor substrates 7L and 7R. In this state, for example, when the user performs an operation of writing a line drawing on the paper 120 of the paper medium 100 fixed to the reading device 2 using the electronic pen 3, the electronic pen 3 comes close to the sensor boards 7L and 7R. Therefore, the resonance circuit of the electronic pen 3 resonates by electromagnetic induction and generates an induction magnetic field.

  Next, the CPU 21 controls the ASICs 28A and 29A to stop the generation of magnetic fields from the loop coils of the sensor substrates 7L and 7R. Each of the loop coils of the sensor substrates 7L and 7R receives an induced magnetic field generated from the resonance circuit of the electronic pen 3. The CPU 21 controls the ASICs 28A and 29A to detect signal currents (reception currents) flowing through the loop coils of the sensor boards 7L and 7R. The ASICs 28A and 29A execute this operation one by one for all the loop coils, so that the position of the electronic pen 3 is detected as coordinate information based on the received current.

  The position specifying table is a table that defines correspondence between all coordinate points of the electronic pen 3 that can be detected by the reading device 2 and coordinate points on the paper 120 fixed to the reading device 2. The CPU 21 can specify the line drawing entry position on the paper 120 based on the detected coordinate point of the electronic pen 3 by referring to the position specifying table.

  In the present embodiment, the CPU 21 can determine which of the entry area 122 and the check box 130 (see FIG. 4) on the sheet 121 has a line drawing based on the detected coordinate point of the electronic pen 3. When a line drawing is written in the writing area 122, the CPU 21 acquires line drawing data for each continuous line drawing and temporarily stores it in the RAM 22. The line drawing data includes a plurality of coordinate information indicating the trajectory of the electronic pen 3 in one entry operation until the electronic pen 3 contacts the paper 121 and leaves. The coordinate information may indicate either absolute coordinates or relative coordinates.

  When a line drawing is entered in the check box 130, the CPU 21 generates stroke data based on the line drawing data temporarily stored in the RAM 22 and stores it in the first storage area of the flash ROM 23. The stroke data includes coordinate information indicating a part or the whole of the line drawing entered in the entry area 122. The detection area includes an instruction area. When the paper medium 100 is loaded in the reading device 2 at an appropriate position, the indication area and the check box 130 correspond to each other in position.

  The smartphone 19 mainly includes a CPU 41, a RAM 42, a flash ROM 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 ROM 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 ROM 43 stores various programs executed by the CPU 41 and stroke data received from the reading device 2. 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 ROM 43. The smartphone 19 may receive a program from an external device (not shown) connected to the smartphone 19 or a network and install the program in the flash ROM 43.

  Character data will be described with reference to FIG. Character data is line drawing data including coordinate information indicating a line drawing representing a character. The flash ROM 23 stores character data corresponding to a plurality of characters. Specifically, the character data includes coordinate information indicating line segments that constitute the character. More specifically, the character data includes coordinate information indicating at least a start point and an end point of a line segment constituting the character. When the character is composed of a plurality of line segments, the character data includes coordinate information indicating at least start points and end points of the plurality of line segments, and information on the order of the plurality of line segments. The order of the plurality of line segments may be determined based on, for example, the character writing order.

  For example, the character “A” illustrated in FIG. 3 includes a line segment C1-C3, a line segment C1-C5, and a line segment C2-C4. The character data of the character “A” includes coordinate information indicating the start point C1 and end point C3 of the line segment C1-C3, the start point C1 and end point C5 of the line segment C1-C5, and the start point C2 and end point C4 of the line segment C2-C4. Including. The character data may include coordinate information indicating the midpoint of the line segment. For example, the character data of the character “A” may include coordinate information of the midpoint C2 of the line segment C1-C3 and the midpoint C4 of the line segment C1-C5. The character data further includes information on the order of the line segment C1-C3, the line segment C1-C5, and the line segment C2-C4. For example, the order of the line segment C1-C3, the line segment C1-C5, and the line segment C2-C4 is this order.

  When the character includes a curve like the character “C”, the character is composed of a plurality of short line segments. Thereby, a plurality of line segments form a curve as a whole.

  A sheet 121, which is an example of the sheet 120, will be described with reference to FIG. The sheet 121 has a rectangular shape that extends in the vertical direction and the horizontal direction. An entry area 122 and a check box 130 are provided on both the front and rear sides of the sheet 121 (that is, two sheets). The entry area 122 and the check box 130 are areas independent of each other on the paper surface of the paper 121. The paper surface of the paper 121 corresponds to one page of the paper medium 100.

  The entry area 122 is an area for entering a line drawing indicating information using the electronic pen 3. Specifically, the entry area 122 has a substantially rectangular shape extending in the vertical direction and the horizontal direction along the edge of the paper surface of the paper 121. The entry area 122 is an area on the paper 121 excluding the check box 130. For example, the user uses the electronic pen 3 to freely enter various information (characters, figures, etc.) to be digitized and stored in the entry area 122.

  The check box 130 is an area in which a line drawing for instructing generation of stroke data based on the line drawing data temporarily stored in the RAM 22 can be entered using the electronic pen 3. In the present embodiment, the check box 130 is provided at the lower right corner of the paper surface of the paper 121. For example, after entering a line drawing in the entry area 122, the user enters a check mark in the check box 130 when he / she wants to save the entered line drawing.

  A data generation process according to the first embodiment will be described with reference to FIG. When the user presses the power switch, the CPU 21 detects an operation of turning on the power of the reading device 2 via the input unit 25. In this case, the CPU 21 starts data generation processing by operating based on the program stored in the flash ROM 23.

  As shown in FIG. 5, when the data generation process is started, the CPU 21 determines whether a generation instruction is accepted (S11). The generation instruction is an instruction for generating stroke data indicating internal information. CPU21 judges that the production | generation instruction | indication is not received, when operation which pushes down the special mode switch for a long time is not detected via the input part 25 (S11: NO). In this case, the CPU 21 repeats the process of S11. CPU21 judges that the production | generation instruction | indication was received, when operation which pushes down a special mode switch for a long time is detected via the input part 25 (S11: YES). When the generation instruction is accepted (S11: YES), the CPU 21 generates stroke data indicating internal information and stores it in the flash ROM 23 (S13).

  Specifically, the CPU 21 acquires internal information from the flash ROM 23. Further, the CPU 21 acquires character data corresponding to the character indicating the internal information from the flash ROM 23. For example, when the internal information is date “2015/03/31”, character data corresponding to each character of “2015/03/31” is acquired. CPU21 produces | generates the stroke data which shows the line drawing showing the character which shows internal information based on the acquired internal information and character data. That is, the numerical data indicating the internal information is converted into stroke data indicating the internal information. The CPU 21 stores the generated stroke data in the first storage area of the flash ROM 23. That is, the stroke data indicating the internal information is stored in the same area as the area where the stroke data indicating the line drawing written on the paper 121 is stored in the flash ROM 23.

  After executing S13, the CPU 21 returns the process to S11. When the CPU 21 detects an operation of turning off the power of the reading device 2 via the input unit 25, the data generation process is terminated.

  When the smartphone 19 receives an instruction to acquire stroke data indicating internal information of the reading device 2, the CPU 41 performs short-range wireless communication with the reading device 2 via the wireless communication unit 44. The stroke data indicating the internal information stored in the flash ROM 23 is transferred from the reading device 2 to the smartphone 19.

  A data generation process according to the second embodiment will be described with reference to FIG. When the user presses the power switch, the CPU 21 detects an operation of turning on the power of the reading device 2 via the input unit 25. In this case, the CPU 21 starts data generation processing by operating based on the program stored in the flash ROM 23.

  As shown in FIG. 6, when the data generation process is started, the CPU 21 determines whether or not an instruction to shift to the maintenance mode has been received (S21). Specifically, the CPU 21 determines whether or not an input of a maintenance mode transition instruction has been received via the input unit 25.

  For example, if the CPU 21 detects an operation of pressing the special mode switch while the power switch is being pressed via the input unit 25, the CPU 21 determines that an instruction to enter the maintenance mode has been received (S21: YES). CPU21 judges that the instruction | indication of maintenance mode transfer is not received when operation which pushes a special mode switch is not detected via the input part 25 with the power switch pressed (S21: NO). For example, when the operation of pressing the power switch has been completed, the CPU 21 determines that the maintenance mode transition instruction has not been received. Further, when the CPU 21 has not detected an operation of pressing the special mode switch for a predetermined time while the power switch is pressed, the CPU 21 determines that the maintenance mode shift instruction has not been received. The predetermined time is, for example, 10 seconds.

  When the instruction for shifting to the maintenance mode has not been received (S21: NO), the CPU 21 shifts to the normal mode (S23) and ends the data generation process. When receiving an instruction to shift to the maintenance mode (S21: YES), the CPU 21 shifts to the maintenance mode (S25).

  The maintenance mode is a mode for executing processing after S27 described later. The normal mode is a mode in which processing after S27 to be described later is not performed, and processing for acquiring line drawing data by detecting the position of the electronic pen 3 as coordinate information when an entry operation is performed with the electronic pen 3 is performed. It is. That is, in the normal mode, as described above, when a line drawing is written in the writing area 122, the CPU 21 acquires line drawing data for each continuous line drawing and temporarily stores it in the RAM 22. When a line drawing is entered in the check box 130, the CPU 21 generates stroke data based on the line drawing data temporarily stored in the RAM 22 and stores it in the first storage area of the flash ROM 23.

  When shifting to the maintenance mode (S25), the CPU 21 determines whether or not a data request command has been received from the smartphone 19 via the wireless communication unit 24 (S27). The data request command is a command for requesting transmission of stroke data to the smartphone 19. In the second embodiment, the data request command is a command for requesting transmission of stroke data indicating internal information to the smartphone 19. When the data request command has not been received (S27: NO), the CPU 21 repeats the process of S27. When the data request command is received (S27: YES), the CPU 21 generates stroke data indicating a line drawing representing the character indicating the internal information and stores it in the flash ROM 23 (S29).

  In detail, CPU21 produces | generates the stroke data which show internal information similarly to the data production | generation process of 1st embodiment. The CPU 21 stores the generated stroke data in the second storage area of the flash ROM 23. The second storage area is an area different from the first storage area in the flash ROM 23. That is, the stroke data indicating the internal information is stored in an area different from the area where the stroke data indicating the line drawing written on the paper 121 is stored in the flash ROM 23.

  After executing S29, the CPU 21 transmits the stroke data generated in S29 and stored in the second storage area of the flash ROM 23 to the smartphone 19 via the wireless communication unit 24 (S31). Thereafter, the CPU 21 returns the process to S27. When the CPU 21 detects an operation of turning off the power of the reading device 2 via the input unit 25, the data generation process is terminated.

The user attaches the paper medium 100 to the reading device 2 such that the front cover 110L is placed on the front surface of the left reading device 2L and the back cover 110R is placed on the front surface of the right reading device 2R. In this state, when the user presses the power switch, the CPU 21 detects an operation of turning on the power of the reading device 2 via the input unit 25. In this case, the CPU 21 starts data generation processing by operating based on the program stored in the flash ROM 23.

  As shown in FIG. 7, when the data generation process is started, the CPU 21 determines whether or not a line drawing has been entered on the paper 121 based on whether or not the detection switch of the electronic pen 3 is ON. Is determined (S41). When the line drawing is on the form 121 (S41: YES), the CPU 21 determines whether or not the line drawing entry position is in the check box 130 (S43).

  When the line drawing entry position is not in the check box 130 (S43: NO), the line drawing entry position is in the entry area 122. The CPU 21 acquires line drawing data for each continuous line drawing (S45). The CPU 21 temporarily stores the acquired line drawing data in the RAM 22. When the line drawing entry position is in the check box 130 (S43: YES), the CPU 21 generates stroke data based on the line drawing data temporarily stored in the RAM 22 and stores it in the first storage area of the flash ROM 23. (S47).

  If the line drawing is not in a state in which the sheet 121 is filled (S41: NO), or after executing S45 or S47, the CPU 21 has received a data request command from the smartphone 19 via the wireless communication unit 24. Is determined (S49). In the third embodiment, the data request command includes information for designating transmission target stroke data among the stroke data stored in the flash ROM 23.

  When the data request command has not been received (S49: NO), the CPU 21 returns the process to S41. When the data request command is received (S49: YES), the CPU 21 determines whether or not the data request command includes a compositing instruction based on the data request command received in S49 (S51). The compositing instruction is an instruction to generate stroke data by compositing the transmission target stroke data with the character data indicating the internal information among the stroke data generated in S47.

CPU21 produces | generates the stroke data which shows the line drawing showing the character which shows internal information based on the acquired internal information and character data. The CPU 21 synthesizes stroke data to be transmitted and stroke data indicating internal information to generate stroke data.

  When the data request command does not include a synthesis instruction (S51: NO), or after executing S53, the CPU 21 transmits stroke data to the smartphone 19 via the wireless communication unit 24 (S55). Specifically, when the stroke data is generated in S53, the CPU 21 transmits the stroke data generated in S53 to the smartphone 19. If the data request command does not include a compositing instruction, the CPU 21 has not generated stroke data in S53. In this case, the CPU 21 transmits the stroke data to be transmitted among the stroke data generated in S <b> 47 to the smartphone 19.

  After executing S55, the CPU 21 returns the process to S41. When the CPU 21 detects an operation of turning off the power of the reading device 2 via the input unit 25, the data generation process is terminated.
