In the

sensor boards

7L and 7R, a 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 28A operates as a master. The ASIC 29A operates as a slave. The ASIC 28A is directly connected to the CPU 21. The 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. 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.

Schematic explanation of the principle of line drawing data acquisition. 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 boards

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.

In a state where a line drawing is written on the paper 120 using the electronic pen 3, writing pressure is applied to the core 31. The inductance of the coil 32 changes according to the writing pressure applied to the core body 31. As a result, the resonance frequency of the resonance circuit of the electronic pen 3 (hereinafter simply referred to as frequency) changes according to the writing pressure applied to the core 31. The CPU 21 detects a change (phase change) in the frequency of the electronic pen 3 and specifies the writing pressure applied to the electronic pen 3. The CPU 21 can detect whether or not a line drawing has been entered on the paper 120 with the specified writing pressure.

The user may use a plurality of electronic pens 3 when writing a line drawing on the paper 120. When a plurality of electronic pens 3 are used, the frequency of the electronic pen 3 is different for each electronic pen 3. For example, the frequency of the electronic pen 3 varies depending on the number of turns of the coil 32. For example, the CPU 21 can specify the electronic pen 3 based on the frequency of the electronic pen 3 when the line drawing is written on the paper 120.

The position specification table 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 front cover 110L, the back cover 110R, and the paper 120 fixed to the reading device 2. It is a table.

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 120 and then leaves. The coordinate information may indicate either absolute coordinates or relative coordinates.

When a line drawing is entered in the third instruction area 150, the CPU 21 generates stroke data based on the line drawing data temporarily stored in the RAM 22 and stores it in 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.

In the second embodiment, the CPU 21 determines, based on the detected coordinate point of the electronic pen 3, the first instruction area 160, the second instruction area 170, and the third instruction area 180 on the back surface 111 of the front cover 110L (see FIG. 7). ), It can be determined whether or not the line drawing is filled in. Further, the CPU 21 can determine in which of the entry area 124 and the fourth instruction area 190 in the sheet 123 the line drawing is entered based on the detected coordinate point of the electronic pen 3. When a line drawing is written in the writing area 124, 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 fourth instruction area 190, the CPU 21 generates stroke data based on the line drawing data temporarily stored in the RAM 22 and stores it in the flash ROM 23.

The basic line function is a function that uses a line drawing entered with the electronic pen 3 as a basic line. The basic line indicates a normal line drawing. The correction line function is a function that uses a line drawing entered with the electronic pen 3 as a correction line. The correction line indicates a line drawing that designates a line drawing to be deleted. Specifically, the correction line indicates a line drawing that designates a line drawing overlapping the correction line as a deletion target. For example, among the color IDs, the color IDs indicating black, red, blue, and white are 0, 1, 2, and 3, respectively. For example, the pen ID “0”, the frequency “f1”, the function ID “100”, and the color ID “0” are associated and stored in the table 301.

If no function ID is specified, the function ID is undefined. When the function ID is undefined and the pen ID and the frequency are stored in association with each other, the function ID indicates a default. In the present embodiment, for example, the default function ID is 100, indicating a basic line. If no color ID is specified, the color ID is undefined. When the color ID is undefined and the pen ID and the frequency are stored in association with each other, the color ID indicates a default. In the present embodiment, for example, the default color ID is 0, indicating black.

As shown in FIG. 5, when the first setting process is started, the CPU 21 determines whether or not a line drawing is written on the paper 121 based on the writing pressure applied to the electronic pen 3. (S11). When the line drawing is not in a state of being written on the sheet 121 (S11: NO), the CPU 21 repeats the process of S11. When the line drawing is on the paper 121 (S11: YES), the CPU 21 specifies the pen ID (S13). Specifically, the CPU 21 acquires the frequency of the electronic pen 3 and specifies the pen ID corresponding to the acquired frequency.

When the same frequency as the frequency acquired in S13 is already stored in the table 301, the CPU 21 determines that the pen ID associated with the substantially same frequency is a pen ID corresponding to the acquired frequency. When the frequency substantially the same as the acquired frequency is not stored in the table 301, the CPU 21 arbitrarily selects a pen ID that is not associated with the frequency among the pen IDs stored in the table 301. The CPU 21 determines that the selected pen ID is a pen ID corresponding to the acquired frequency. Note that the pen ID that is not associated with the frequency may not be stored in the table 301 in advance. In this case, the CPU 21 may set a new pen ID as a pen ID that is not associated with a frequency.

After executing S13, the CPU 21 determines whether there is a setting check (S15). When the line drawing entry position is not in either the first instruction area 130 or the second instruction area 140, the CPU 21 determines that there is no setting check (S15: NO). In this case, the CPU 21 returns the process to S11. If the line drawing entry position is in either the first instruction area 130 or the second instruction area 140, the CPU 21 determines that there is a setting check (S15: YES). In this case, the CPU 21 specifies a check ID (S17). Specifically, the CPU 21 determines which of the

indication areas

131, 132, and 141 to 144 is the line drawing entry position. The CPU 21 specifies the check ID of the designated area determined to have an entry position.

In the first embodiment, for example, the check IDs of the

instruction areas

131 and 132 are the function IDs “100” and “101”, respectively. For example, the check IDs of the

instruction areas

141, 142, 143, and 144 are the color IDs “0”, “1”, “2”, and “3”, respectively. As described above, in this embodiment, the function ID “100” indicates a basic line, and the function ID “101” indicates a correction line. The color IDs “0”, “1”, “2”, and “3” indicate black, red, blue, and white, respectively.

After executing S17, the CPU 21 determines whether or not the function of the electronic pen 3 is designated based on the check ID (S19). When the check ID specified in S17 is a function ID, the CPU 21 determines that the function of the electronic pen 3 has been designated (S19: YES). In this case, the CPU 21 updates the table 301 by associating the pen ID specified in S13 with the frequency acquired in S13 and the check ID (function ID) specified in S17 in the table 301 (S21). Thereafter, the CPU 21 returns the process to S11.

If the check ID specified in S17 is not a function ID, the CPU 21 determines that the function of the electronic pen 3 is not designated (S19: NO). In this case, the check ID is a color ID. Therefore, the color of the electronic pen 3 is designated. The CPU 21 updates the table 301 by associating the pen ID specified in S13 with the frequency acquired in S13 and the check ID (color ID) specified in S17 in the table 301 (S23). Thereafter, 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 CPU 21 ends the first setting process.

Next, the second setting process will be described with reference to FIG. As described above, in the first embodiment, the CPU 21 executes the second setting process in parallel with the first setting process. When the second setting process is started, the CPU 21 determines whether or not a line drawing has been entered on the paper 121 based on the writing pressure applied to the electronic pen 3 (S31). When the line drawing is not in a state of being written on the sheet 121 (S31: NO), the CPU 21 repeats the process of S31. When the line drawing is on the form 121 (S31: YES), the CPU 21 determines whether or not the line drawing entry position is in the writing area 122 (S33).

If the line drawing entry position is not in the entry area 122 (S33: NO), the CPU 21 returns the process to S31. When the line drawing entry position is in the entry area 122 (S33: YES), the CPU 21 obtains line drawing data and the frequency of the electronic pen 3 for each continuous line drawing (S35). The CPU 21 associates the acquired line drawing data with the frequency and stores them in the RAM 22. After executing S35, the CPU 21 refers to the table 301 updated in the first setting process (see FIG. 5), and determines the attribute of the line drawing indicated by the line drawing data acquired in S35 (S37). Specifically, the CPU 21 determines at least one of the function and color of the line drawing indicated by the line drawing data acquired in S35.

Specifically, the CPU 21 acquires the line drawing data stored in the RAM 22 and the frequency associated with the line drawing data. The CPU 21 refers to the table 301 stored in the flash ROM 23 and identifies the pen ID associated with the acquired frequency. The CPU 21 acquires a function ID and a color ID associated with the specified pen ID. The CPU 21 determines the function and color of the line drawing based on the acquired function ID and color ID.

As described above, when the function ID is undefined, the function ID indicates a default (for example, a basic line). As described above, when the color ID is undefined, the color ID indicates a default (for example, black). The CPU 21 stores the determined attributes (function and color) in the RAM 22 in association with the line drawing data. When the acquired frequency is not stored in the table 301, the CPU 21 may determine that the function and color of the line drawing indicated by the line drawing data associated with the frequency are default (basic line and black). .

After executing S37, the CPU 21 returns the process to S31. When the CPU 21 detects an operation to turn off the power of the reading device 2 via the input unit 25, the CPU 21 ends the second setting process.

When a line drawing is entered in the third instruction area 150 during the execution of the second setting process, the CPU 21 determines that an instruction for generating stroke data has been received. In this case, the CPU 21 generates stroke data based on the line drawing data stored in the RAM 22. Specifically, the stroke data includes line drawing data and attribute information associated with the line drawing data. The CPU 21 stores the generated stroke data in the flash ROM 23.

With reference to FIG. 4, in the first embodiment, the first specific example and the second specific example in which the attribute of the electronic pen 3 is determined by the reading device 2 and associated with the line drawing will be described. The paper medium 100 is mounted on the front surface of the reading device 2 with the power supply of the reading device 2 turned on.

In the first specific example, the user uses one electronic pen 3. The user enters a check mark in the instruction area 143 using the electronic pen 3. The reading device 2 identifies the pen ID (for example, 0) and the check ID (color ID) “2” of the instruction area 143, and updates the table 301 (S11: YES, S13, S15: YES, S17, S19: NO, S23). In this case, for example, the acquired frequency “f1” and color ID “2” are associated with the pen ID “0” and stored in the table 301. Thereafter, the user uses the electronic pen 3 to enter the line drawing 201 indicating “123” in the entry area 122. In the reading device 2, line drawing data indicating the line drawing 201 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines that the attribute (color) of the line drawing 201 is blue (S37).

Next, the user uses the electronic pen 3 to enter check marks in the

instruction areas

131 and 141. The reading device 2 identifies the pen ID “0”, the check ID (function ID) “100” of the instruction area 131, and the check ID (color ID) “0” of the instruction area 141, and updates the table 301 (S11). : YES, S13, S15: YES, S17, S19: YES, S21, S11: YES, S13, S15: YES, S17, S19: NO, S23). In this case, for example, the frequency “f1”, the function ID “100”, and the color ID “0” are associated with the pen ID “0” and stored in the table 301. That is, the attribute information of the pen ID “0” is updated.

Thereafter, the user uses the electronic pen 3 to enter the line drawing 202 indicating “ABC” in the entry area 122. In the reading device 2, line drawing data indicating the line drawing 202 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines the attribute (function and color) of the line drawing 202 as a basic line and black (S37).

Next, the user enters a check mark in the instruction area 132 using the electronic pen 3. The reading device 2 specifies the pen ID “0” and the check ID (function ID) “101” of the instruction area 132 and updates the table 301 (S11: YES, S13, S15: YES, S17, S19: YES, S21). In this case, for example, the frequency “f1”, the function ID “101”, and the color ID “0” are associated with the pen ID “0” and stored in the table 301. That is, the attribute information of the pen ID “0” is updated.

Thereafter, the user uses the electronic pen 3 to enter a line drawing 203 indicating a horizontal line on the line drawing area 202 in the entry area 122. In the reading device 2, line drawing data indicating the line drawing 203 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines the attribute (function and color) of the line drawing 203 as a correction line and black (S37).

In the second specific example, the user uses a plurality of electronic pens 3. The user enters a check mark in the instruction area 143 using the electronic pen 3. The reading device 2 identifies the pen ID (for example, 0) and the check ID (color ID) “2” of the instruction area 143, and updates the table 301 (S11: YES, S13, S15: YES, S17, S19: NO, S23). In this case, for example, the acquired frequency “f1” and color ID “2” are associated with the pen ID “0” and stored in the table 301. Thereafter, the user uses the same electronic pen 3 to enter the line drawing 201 indicating “123” in the entry area 122. In the reading device 2, line drawing data indicating the line drawing 201 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines that the attribute (color) of the line drawing 201 is blue (S37).

Next, the user enters check marks in the

instruction areas

131 and 141 using the electronic pen 3 different from the electronic pen 3 used when the line drawing 201 is entered. The reading device 2 identifies the pen ID (for example, 1), the check ID (function ID) “100” of the instruction area 131, and the check ID (color ID) “0” of the instruction area 141, and updates the table 301. (S11: YES, S13, S15: YES, S17, S19: YES, S21, S11: YES, S13, S15: YES, S17, S19: NO, S23). In this case, for example, the acquired frequency “f2”, function ID “100”, and color ID “0” are associated with the pen ID “1” and stored in the table 301. That is, the pen ID given to the electronic pen 3 used when the check marks are written in the

instruction areas

131 and 141 is different from the pen ID of the electronic pen 3 used when the check marks are written in the instruction area 143.

Thereafter, the user enters the line drawing 202 indicating “ABC” in the entry area 122 using the electronic pen 3 used when the check marks are entered in the

instruction areas

131 and 141. In the reading device 2, line drawing data indicating the line drawing 202 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines the attribute (function and color) of the line drawing 202 as a basic line and black (S37).

Next, the user enters a check mark in the instruction area 132 using the electronic pen 3 different from the electronic pen 3 used when the

line drawings

201 and 202 are entered. The reading device 2 identifies the pen ID (for example, 2) and the check ID (function ID) “101” of the instruction area 132, and updates the table 301 (S11: YES, S13, S15: YES, S17, S19: YES, S21). In this case, for example, the acquired frequency “f3” and the function ID “101” are associated with the pen ID “2” and stored in the table 301. That is, the pen ID given to the electronic pen 3 used when the check mark is entered in the instruction area 132 is the pen ID of the electronic pen 3 used when the instruction area 143 is entered and the

check areas

131 and 141 are checked. It is different from the pen ID of the electronic pen 3 used for writing.

Thereafter, the user uses the electronic pen 3 used when the line drawing 203 is written, and enters the line drawing 203 indicating a horizontal line on the line drawing 202 in the writing area 122. In the reading device 2, line drawing data indicating the line drawing 203 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines the attribute (function) of the line drawing 203 as a correction line (S37).

In the first specific example and the second specific example, when the user finishes the entry of information in the entry area 122 and the designation of the attribute, the user enters a check mark in the third instruction area 150 using the electronic pen 3. The reading device 2 generates stroke data based on the line drawing data stored in the RAM 22 and stores the stroke data in the flash ROM 23. The stroke data includes line drawing data and attribute information associated with the line drawing data. Accordingly, the line drawing entered in the entry area 122 and the line drawing attributes are determined.

With reference to FIG. 7, the back surface 111 of the front cover 110L, which is an example of a pen setting sheet according to the second embodiment, will be described. The pen setting sheet is a surface on which a symbol used for presetting the attributes of the electronic pen 3 is printed. The pen setting sheet may be any of the front surface of the front cover 110L, the front surface of the back cover 110R, the back surface of the back cover 110R, and the paper surface of the paper 120. The front cover 110L has a rectangular shape extending in the vertical direction and the horizontal direction. On the back surface 111, a first instruction area 160, a second instruction area 170, and a third instruction area 180 are provided. The first instruction area 160, the second instruction area 170, and the third instruction area 180 are areas independent from each other on the back surface 111.

The first instruction area 160 and the second instruction area 170 are areas where a line drawing for designating attributes of the electronic pen 3 can be entered using the electronic pen 3. The attribute of the electronic pen 3 indicates the attribute of the line drawing entered in the entry area 124 (see FIG. 8) of the paper 123 using the electronic pen 3. The first instruction area 160 is an area in which a line drawing for designating the function of the electronic pen 3 can be entered. The first instruction area 160 of the second embodiment includes an instruction area 161 and an instruction area 162. The instruction area 161 and the instruction area 162 of the second embodiment are check boxes provided in the upper left part of the back surface 111, respectively. The instruction area 162 is provided side by side on the right side of the instruction area 161.

The instruction area 161 is an area in which a line drawing for designating a basic line function can be entered as a function of the electronic pen 3 as in the instruction area 131 of the first embodiment. The instruction area 162 is an area in which a line drawing for designating a correction line function can be entered as a function of the electronic pen 3 as in the instruction area 132 of the first embodiment. For example, when the user wants to specify the function of the electronic pen 3, he / she enters a check mark in one of the

instruction areas

161 and 162.

The second instruction area 170 is an area in which a line drawing for designating the color of the electronic pen 3 can be entered. The color of the electronic pen 3 indicates the color of the line drawing entered in the entry area 124 using the electronic pen 3. The second instruction area 170 of the second embodiment includes an instruction area 171, an instruction area 172, an instruction area 173, and an instruction area 174. The

instruction areas

171, 172, 173, and 174 of the second embodiment are check boxes provided below the

instruction areas

161 and 162 in the upper left part of the back surface 111, respectively. The

instruction areas

171, 172, 173, and 174 are provided in this order from left to right.

The instruction area 171 is an area in which a line drawing for designating black as the color of the electronic pen 3 can be entered. The instruction area 172 is an area in which a line drawing for designating red as the color of the electronic pen 3 can be entered. The instruction area 173 is an area in which a line drawing for designating blue as the color of the electronic pen 3 can be entered. The instruction area 174 is an area in which a line drawing for designating white as the color of the electronic pen 3 can be entered. For example, when the user wants to specify the color of the electronic pen 3, he / she enters a check mark in any of the instruction areas 171 to 174.

The third instruction area 180 is an area in which a line drawing for determining the attributes of the electronic pen 3 can be entered using the electronic pen 3. The third indication area 180 of the second embodiment is a check box provided at the lower right corner of the back surface 111. For example, after entering a line drawing in at least one of the first instruction area 160 and the second instruction area 170, the user enters a check mark in the third instruction area 180 in order to determine the attribute of the designated electronic pen 3.

A sheet 123 according to the second embodiment, which is an example of the sheet 120, will be described with reference to FIG. The sheet 123 has a rectangular shape extending in the vertical direction and the horizontal direction. An entry area 124 and a fourth instruction area 190 are provided on both front and rear surfaces (that is, two paper surfaces) of the sheet 123, respectively. The entry area 124 and the fourth instruction area 190 are areas independent from each other on the paper surface of the sheet 123. The paper surface of the paper 123 corresponds to one page of the paper medium 100.

The entry area 124 is an area for entering a line drawing indicating information using the electronic pen 3. Specifically, the entry area 124 has a substantially rectangular shape extending in the vertical direction and the horizontal direction along the edge of the paper surface of the paper 123. The entry area 124 is an area on the paper 123 excluding the fourth instruction area 190. For example, the user uses the electronic pen 3 to freely enter various information (characters, numbers, symbols, figures, etc.) to be digitized and stored in the entry area 124.

The fourth instruction area 190 is an area where a line drawing for instructing generation of stroke data based on the line drawing data stored in the RAM 22 can be entered using the electronic pen 3. Specifically, the fourth instruction area 190 is a check box provided at the lower right corner of the sheet 123. For example, after entering a line drawing in the entry area 124, the user enters a check mark in the fourth instruction area 190 when he / she wants to save the entered line drawing.

The first setting process and the second setting process according to the second embodiment will be described with reference to FIGS. First, the user mounts the paper medium 100 on the reading device 2 at an appropriate position. 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. At this time, the user places the front cover 110L of the paper medium 100 in front of the bag portion 4A without inserting it into the bag portion 4A of the cover 4. The user places all sheets 120 of the paper medium 100 in front of the right reading device 2R. Thus, only the front cover 110L is placed on the left reading device 2L, and the back surface 111 is disposed in front of the left reading device 2L.

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 the first setting process by operating based on the program stored in the flash ROM 23.

As shown in FIG. 9, when the first setting process is started, the CPU 21 determines whether an instruction to shift to the setting mode has been received (S51). CPU21 judges that the instruction | indication of a setting mode transfer is not received, when the operation which pushes down a special mode switch for a long time is not detected via the input part 25 (S51: NO). In this case, the CPU 21 repeats the process of S51. CPU21 judges that the instruction | indication of setting mode transfer was received, when operation which pushes down a special mode switch for a long time is detected via the input part 25 (S51: YES).

When the instruction for shifting to the setting mode is received (S51: YES), the CPU 21 shifts to the setting mode (S53). Specifically, the CPU 21 reads a position specifying table corresponding to the back surface 111 from the flash ROM 23 and stores it in the RAM 22. The CPU 21 can specify the positions of the

instruction areas

161, 162, 171 to 174 and the third instruction area 180 on the back surface 111 based on the detected coordinate point of the electronic pen 3 by referring to the position specifying table.

After executing S53, the CPU 21 determines based on the writing pressure applied to the electronic pen 3 whether or not a line drawing has been entered on the back surface 111 (S55). When the line drawing is not in the state of being written on the back surface 111 (S55: NO), the CPU 21 repeats the process of S53. When the line drawing is written on the back surface 111 (S55: YES), the CPU 21 specifies the pen ID as in S13 of the first setting process according to the first embodiment (S57).

CPU 21 determines whether there is a setting check (S59). If the line drawing entry position is not in either the first instruction area 160 or the second instruction area 170, the CPU 21 determines that there is no setting check (S59: NO). In this case, the CPU 21 returns the process to S53. If the line drawing entry position is in either the first instruction area 160 or the second instruction area 170, the CPU 21 determines that there is a setting check (S59: YES). In this case, the CPU 21 specifies a check ID (S61). Specifically, the CPU 21 determines which of the designated

areas

161, 162, and 171 to 174 is the line drawing entry position. The CPU 21 specifies the check ID of the designated area determined to have an entry position.

In the second embodiment, for example, the check IDs of the

instruction areas

161 and 162 are function IDs “100” and “101”, respectively. For example, the check IDs of the

instruction areas

171, 172, 173, and 174 are color IDs “0”, “1”, “2”, and “3”, respectively. As described above, the function ID “100” indicates a basic line, and the function ID “101” indicates a correction line. The color IDs “0”, “1”, “2”, and “3” indicate black, red, blue, and white, respectively.

After executing S61, the CPU 21 determines whether or not the function of the electronic pen 3 is designated based on the check ID, similarly to S19 of the first setting process of the first embodiment (S63). When the function of the electronic pen 3 is designated (S63: YES), the CPU 21 stores the pen ID specified in S57 in association with the frequency acquired in S57 and the check ID (function ID) specified in S61 in the table 301. As a result, the table 301 is updated (S65).

When the function of the electronic pen 3 is not designated (S63: NO), the color of the electronic pen 3 is designated. Therefore, the CPU 21 updates the table 301 by associating the pen ID specified in S57 with the frequency acquired in S57 and the check ID (color ID) specified in S61 in the table 301 (S67).

After executing S65 or S67, the CPU 21 determines whether an instruction to end the setting mode has been received (S69). Specifically, the CPU 21 determines whether or not a line drawing has been entered in the third instruction area 180. When no line drawing is entered in the third instruction area 180, the CPU 21 determines that an instruction to end the setting mode has not been received (S69: NO). In this case, the CPU 21 returns the process to S55. When a line drawing is entered in the third instruction area 180, the CPU 21 determines that an instruction to end the setting mode has been received (S69: YES). In this case, the CPU 21 ends the first setting process.

In the second embodiment, when the CPU 21 completes the first setting process, it operates based on the program stored in the flash ROM 23 to start the second setting process shown in FIG. The user inserts the front cover 110 </ b> L of the paper medium 100 into the bag portion 4 </ b> A of the cover 4 and places the paper medium 100 on the reading device 2 at an appropriate position.

When the second setting process is started, as in the first embodiment, the CPU 21 determines whether or not a line drawing has been entered on the paper 123 based on the writing pressure applied to the electronic pen 3. (S31). When the line drawing is not in a state of being written on the sheet 123 (S31: NO), the CPU 21 repeats the process of S31. When the line drawing has been entered on the sheet 123 (S31: YES), the CPU 21 determines whether or not the line drawing entry position is in the entry area 124 (S33).

If the line drawing entry position is not in the entry area 124 (S33: NO), the CPU 21 returns the process to S31. When the line drawing entry position is in the entry area 124 (S33: YES), the CPU 21 acquires line drawing data and the frequency of the electronic pen 3 for each continuous line drawing (S35). The CPU 21 associates the acquired line drawing data with the frequency and stores them in the RAM 22. After executing S35, the CPU 21 refers to the table 301 updated in the first setting process (see FIG. 9), and determines the attribute of the line drawing indicated by the line drawing data acquired in S35 (S37). Specifically, the CPU 21 determines at least one of the function and color of the line drawing indicated by the line drawing data acquired in S35.

As described above, when the function ID is undefined, the function ID indicates a default (for example, a basic line). As described above, when the color ID is undefined, the color ID indicates a default (for example, black). The CPU 21 stores the determined attribute (function and color) in the RAM 22 in association with the line drawing data. When the acquired frequency is not stored in the table 301, the CPU 21 may determine that the function and color of the line drawing indicated by the line drawing data associated with the frequency are default (basic line and black). .

With reference to FIG.7 and FIG.8, in 2nd embodiment, the attribute of the electronic pen 3 is determined with the reader 2, and the 3rd specific example matched with a line drawing is demonstrated. The paper medium 100 is mounted on the front surface of the reading device 2 with the power supply of the reading device 2 turned on. Only the front cover 110L is placed on the left reading device 2L, and the back surface 111 is disposed in front of the left reading device 2L. When the user depresses the special mode switch for a long time, the reading device 2 shifts to the setting mode (S51: YES, S53).

In the third specific example, the user uses a plurality of electronic pens 3. The user enters a check mark in the instruction area 161 using the electronic pen 3. The reading device 2 identifies the pen ID (for example, 0) and the check ID (function ID) “100” of the instruction area 161, and updates the table 301 (S55: YES, S57, S59: YES, S61, S63: YES, S65). In this case, for example, the acquired frequency “f1” and function ID “100” are associated with the pen ID “0” and stored in the table 301.

Thereafter, the user enters a check mark in the instruction area 171 using the same electronic pen 3. The reading device 2 identifies the pen ID (for example, 0) and the check ID (color ID) “0” of the instruction area 171 and updates the table 301 (S69: NO, S55: YES, S57, S59: YES, S61, S63: NO, S67). In this case, for example, the frequency “f1”, the function ID “100”, and the color ID “0” are associated with the pen ID “0” and stored in the table 301.

Next, the user enters a check mark in the instruction area 162 using an electronic pen 3 different from the electronic pen 3 used when the check mark is entered in the instruction area 171. The reading device 2 identifies the pen ID (for example, 1) and the check ID (function ID) “101” of the instruction area 162, and updates the table 301 (S69: NO, S55: YES, S57, S59: YES, S61, S63: YES, S65). In this case, for example, the acquired frequency “f2” and the function ID “101” are associated with the pen ID “1” and stored in the table 301.

Then, the user enters a check mark in the third indication area 180 using the same electronic pen 3. The reading device 2 determines that an instruction to end the setting mode has been received (S69: YES), and ends the setting mode. In this case, the attributes of the electronic pen 3 with the pen ID “0” are the basic line and black. The attribute of the electronic pen 3 with the pen ID “1” is a correction line.

The user inserts the front cover 110L into the bag portion 4A of the cover 4 and places the paper medium 100 in the reading device 2 at an appropriate position. The user enters a line drawing 206 indicating “123” in the entry area 124 of the paper 123 using the electronic pen 3 with the pen ID “0”. In the reading device 2, line drawing data indicating the line drawing 206 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines the attribute (function and color) of the line drawing 206 as the basic line and black based on the pen ID “0” of the electronic pen 3 (S37).

The user uses the electronic pen 3 with the pen ID “1” to enter a line drawing 207 indicating a horizontal line on the line drawing “3” to be deleted from the line drawing 206. In the reading device 2, line drawing data indicating the line drawing 207 is acquired (S31: YES, S33: YES, S35). The reading device 2 refers to the table 301 and determines the attribute (function) of the line drawing 207 as a correction line based on the pen ID “1” (S37). Here, in the table 301, the color ID associated with the pen ID “1” is undefined. Therefore, the color ID indicates the default black.

When the user finishes entering information in the entry area 124, the user enters a check mark in the fourth instruction area 190 using the electronic pen 3.

The CPU 21 may not include the line drawing data indicating the line drawing of the correction line and the line drawing data indicating the line drawing of the basic line overlapping the correction line in the stroke data. In this case, the line drawing data included in the stroke data is only line drawing data indicating a basic line drawing that does not overlap the correction line. Therefore, when generating image data based on stroke data, the CPU 41 does not need to determine which line drawing data is used to generate image data.

As described above, according to the above embodiment, the CPU 21 acquires the frequency of the electronic pen 3 and specifies the pen ID (S13 in FIG. 5 and S55 in FIG. 9).

The ID and the attribute corresponding to the specified indication area are associated and stored in the flash ROM 23 (S11: YES, S13, S15: YES, S17, S19, S21 or S23). When a line drawing is newly entered in the entry area 122, the line drawing data of the newly entered line drawing is acquired and the attributes of the line drawing are determined (S31: YES, S33: YES, S35, S37). Therefore, the user can designate line drawing attributes each time a line drawing is entered.

In the second embodiment, when receiving an instruction to start the second setting process (S51: YES), the CPU 21 shifts to the setting mode (S53) and specifies the pen ID (S57). When a line drawing is entered in at least one of the first instruction area 160 and the second instruction area 170, the CPU 21 specifies the instruction area in which the line drawing is entered (S59: YES, S61). The CPU 21 stores the specified pen ID and the attribute corresponding to the specified instruction area in the flash ROM 23 in association with each other (S65, S67). Therefore, the user can specify the attribute of the electronic pen 3 when an instruction to shift to the setting mode is input to the reading device 2.
