  For example, it is conceivable to take a questionnaire using a written data processing system. In this case, a questionnaire sheet provided with a plurality of options is attached to the reading device. The respondent of the questionnaire writes a check mark in one option from a plurality of options provided on the questionnaire sheet. Respondents may accidentally write a check mark on an inappropriate option. In this case, the respondent rewrites a check mark in an appropriate option. Thereafter, the respondent makes a correction by writing a line drawing of a specific shape such as a double line in an inappropriate option in which a check mark is written by mistake.

  It is conceivable to apply the technique of the writing data processing system described above to determine whether the written line drawing is a line drawing having a specific shape. When the written line drawing has a specific shape, the reading apparatus can invalidate the option in which the line drawing of the specific shape is written as an inappropriate option. However, the line drawing written to correct an inappropriate option is not limited to a specific shape. For example, the respondent may make a correction by writing a line drawing having a shape formed by reciprocating a plurality of times in the left-right direction. For this reason, it may be difficult to determine whether the written line drawing has a specific shape. Therefore, there is a possibility that an inappropriate option in which the respondent mistakenly wrote a check mark is specified as an effective option without being invalidated.

The line drawing includes letters, numbers, symbols, figures, and the like. The reading device 2 acquires the position of the electronic pen 3 in the writing process.

  The PC 19 acquires a plurality of positions specified by the reading device 2. The PC 19 specifies a line drawing written on the paper 111 by the electronic pen 3 based on the acquired plurality of positions. The PC 19 can execute processing corresponding to the specified line drawing.

  The PC 19 can create an image file of an image including at least the specified line drawing. The user inputs an operation for selecting one of the plurality of created image files via the input unit 191. The PC 19 causes the display 192 to display an image corresponding to the selected image file. The user can visually recognize an image including 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.

  The reading device 2 has a rectangular thin plate shape. On the front surface of the reading device 2, there is a mounting portion 2A. An LED 5 is provided at the upper end of the reading device 2. On the rear side of the mounting portion 2A, there is a sensor substrate 7 (see FIG. 2) described later. The paper medium 100 is detachably attached to the attachment portion 2A. The paper medium 100 includes a plurality of sheets 111 with upper end portions bound. A format indicating a layout of characters, line segments, and the like is printed on the paper 111 in advance. The format of the plurality of sheets 111 may be different for each of the plurality of sheets 111. The paper medium 100 is mounted on the mounting portion 2A in a state where the paper medium 100 is positioned on the mounting portion 2A by a double-sided tape and an adhesive resin film. The user can write a line drawing on the paper 111 of the paper medium 100 attached to the attachment unit 2 </ b> A using the electronic pen 3.

  The electronic pen 3 is a known electromagnetic induction type electronic pen, and includes a cylindrical body 30, a core body 31, a coil 32, capacitors 33 and 35, a substrate 34, an ink storage unit 36, a switch (not shown), and the like. The cylindrical body 30 has a cylindrical shape. Inside the cylindrical body 30, a part of the core body 31, a coil 32, capacitors 33 and 35, a substrate 34, and an ink storage unit 36 are stored. 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 unit 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 paper 111 using the electronic pen 3, a line drawing is formed on the paper 111 by the ink.

The flash memory 23 stores a program executed by the CPU 21. The program is stored in advance in the flash memory 23 when the reader 2 is shipped. The program may be rewritable after shipment. 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 (for example, the PC 19). 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.

  Hereinafter, as shown in FIG. 3, a region corresponding to a portion where the loop coil is arranged on the sensor substrate 7 (see FIG. 2) in the front surface of the reading device 2 (see FIG. 1) is referred to as a detection region 90. The ASIC 28A uses a predetermined position as an origin, and sets the horizontal direction (horizontal direction) and the vertical direction (vertical direction) as the X-axis direction and the Y-axis direction of coordinates, respectively. The detection area 90 includes target areas 91A to 91C, 92A to 92C, 93A to 93C, 94A to 94C, and an end area 95. The target areas 91A to 91C are arranged in order from the left. The target areas 92A to 92C are arranged in order from the left. The target areas 93A to 93C are arranged in order from the left. The target areas 94A to 94C are arranged in order from the left. The target areas 91A to 91C, the target areas 92A to 92C, the target areas 93A to 93C, and the target areas 94A to 94C are arranged in order from the top. Hereinafter, when any of the target areas 91A to 91C, 92A to 92C, 93A to 93C, and 94A to 94C is not specified, it is referred to as a target area. The target area is square. The end area 95 is arranged at the lower right corner of the detection area 90. The end region 95 has a rectangular shape that is long in the left-right direction. The target areas 91A to 91C, the target areas 92A to 92C, the target areas 93A to 93C, and the target areas 94A to 94C belong to a group of target areas 91 to 94, respectively. When any one of the group of target areas 91 to 94 is not specified, it is referred to as a group of target areas.

  The operation principle of the reading device 2 will be described with reference to FIG. 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. Thereby, a magnetic field is generated from each of the plurality of loop coils of the sensor substrate 7.

  In this state, for example, it is assumed that the user performs an operation of writing a line drawing on the paper 111 of the paper medium 100 attached to the attachment unit 2 </ b> A using the electronic pen 3. In this case, the electronic pen 3 is close to the sensor substrate 7. The core 31 of the electronic pen 3 enters the cylinder 30 according to 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.

  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 28 </ b> A specifies the position of the loop coil when the received current is detected as coordinate data indicating the position of the electronic pen 3. The ASIC 28A outputs the specified coordinate data to the CPU 21. When the coordinate data is output from the ASIC 28A, the electronic pen 3 is close to the sensor substrate 7 on the rear side of the mounting portion 2A, and the core body 31 enters the cylindrical body 30 (see FIG. 1). For this reason, the CPU 21 determines that a line drawing is written by the electronic pen 3 on the paper 111 of the paper medium 100 attached to the attachment unit 2A.

  When determining that the line drawing is written, the CPU 21 acquires the coordinate data output from the ASIC 28A. The CPU 21 acquires the time when the acquired coordinate data is detected. The CPU 21 stores the acquired coordinate data and time data in a predetermined area of the RAM 22 in association with each other. The CPU 21 repeats the acquisition of coordinate data and time data from the start of writing a line drawing with the electronic pen 3 to the end of writing. Hereinafter, a line drawing written by a series of writings is referred to as one unit of line drawing from the start to the end of writing of the line drawing (from the time when the electronic pen 3 is turned on to the next time it is turned off). . Coordinate data that can identify a unit of line drawing and a plurality of time data associated with each coordinate data are collectively referred to as line drawing data.

  The CPU 21 determines whether a line drawing is written with the electronic pen 3 (S11). When the switch of the electronic pen 3 is turned on, the ASIC 28A outputs coordinate data to the CPU 21. When the CPU 21 detects the coordinate data output from the ASIC 28A, the CPU 21 determines that the line drawing is written by the electronic pen 3 (S11: YES). The CPU 21 acquires coordinate data output from the ASIC 28A. The CPU 21 acquires time data indicating the time when the acquired coordinate data is detected. The CPU 21 associates the acquired coordinate data with the acquired time data and stores them in a predetermined area of the RAM 22 (S12).

  The CPU 21 determines whether writing with the electronic pen 3 has been completed (S13). When detecting coordinate data output from the ASIC 28A, the CPU 21 determines that writing with the electronic pen 3 has not been completed (S13: NO). CPU21 repeats the process of S12. That is, the CPU 21 repeatedly executes the process of S12 from the start of writing with the electronic pen 3 to the end thereof (that is, while one unit of line drawing is being written). When the switch of the electronic pen 3 is turned off, the output of the coordinate data to the CPU 21 by the ASIC 28A ends. If the CPU 21 does not detect the coordinate data from the ASIC 28A, the CPU 21 determines that the writing with the electronic pen 3 has ended (S13: YES). In this case, the predetermined area of the RAM 22 is in a state in which line drawing data indicating one unit of line drawing written by the electronic pen 3 is stored. The CPU 21 stores the line drawing data stored in the predetermined area of the RAM 22 in the table 22A shown in FIG. 7 (S14). As shown in FIG. 7, the line drawing data is stored in the table 22 </ b> A in association with an index indicating the order in which one unit of line drawing is written. The CPU 21 deletes the line drawing data stored in the table 22 </ b> A from the predetermined area of the RAM 22.

  As shown in FIG. 6, the CPU 21 determines whether one unit of line drawing has been written in the end box 75 (S15). Specifically, the CPU 21 determines whether at least a part of the written unit line drawing is written in the end box 75. When all the coordinate data included in the line drawing data stored latest in the table 22A indicates a position outside the end area 95, the CPU 21 determines that one unit of line drawing is written outside the end box 75 ( S15: NO). CPU21 returns a process to the process of S11. When at least one of the coordinate data included in the line drawing data stored latest in the table 22 </ b> A indicates the position in the end area 95, the CPU 21 determines that one unit of line drawing has been written in the end box 75. (S15: YES). The CPU 21 creates an answer file based on the table 22A (see FIG. 7) (S16). The answer file includes all line drawing data stored in the table 22A in association with the index. The CPU 21 stores the created answer file in the flash memory 23. The CPU 21 deletes the line drawing data from the table 22A. CPU21 returns a process to the process of S11.

  When the CPU 21 does not detect the coordinate data from the ASIC 28A, the CPU 21 determines that the line drawing is not written by the electronic pen 3 (S11: NO). The CPU 21 determines whether an acquisition command for transmitting an answer file is received from the PC 19 via the wireless communication unit 24 (S21). When the acquisition command has not been received (S21: NO), the CPU 21 returns the process to the process of S11. When the acquisition command is received (S21: YES), the CPU 21 determines whether the answer file is stored in the flash memory 23 (S22). When the answer file is not stored in the flash memory 23 (S22: NO), the CPU 21 returns the process to S11. When the answer file is stored in the flash memory 23 (S22: YES), the CPU 21 transmits the answer file to the PC 19 via the wireless communication unit 24 (S23). The CPU 21 deletes the transmitted answer file from the flash memory 23.

  In the example of FIG. 4, the CPU 21 executes the processing of S11 to S14 each time one unit of line drawing 9A to 9M is written, thereby converting line drawing data indicating each unit of line drawing 9A to 9M into the index number. . 1 to 13 and stored in the table 22A (see FIG. 7). When one unit of line drawing 9A to 9L is written, the CPU 21 determines that one unit of line drawing is written outside the end box 75 (S15: NO). On the other hand, when the line drawing 9M is written, the CPU 21 determines that one unit of line drawing is written in the end box 75 (S15: YES). In this case, the CPU 21 creates an answer file based on the table 22A shown in FIG. 7 (S16). The CPU 21 stores the created answer file in the flash memory 23. When receiving the acquisition command (S21: YES), the CPU 21 transmits the answer file created based on the table 22A shown in FIG. 7 to the PC 19 via the wireless communication unit 24 (S23).

  The second main process will be described with reference to FIG. The CPU 41 performs the second main process by operating based on a program stored in the flash memory 43 when an application activation operation for wireless connection with the reading device 2 is performed via the input unit 191. Start.

  The CPU 41 transmits acquisition commands to the reading device 2 at regular intervals via the wireless communication unit 44 (S31). The CPU 41 receives the answer file from the reading device 2 via the wireless communication unit 44 (S32). The CPU 41 stores the received answer file in the RAM 42.

  The CPU 41 refers to the index of the answer file stored in the RAM 42 and selects one line drawing data in the order in which one unit of line drawing is written (S33). That is, the CPU 41 selects line drawing data indicating a unit of line drawing written next to the unit of line drawing indicated by the line drawing data selected in the previous processing of S33. The CPU 41 determines whether at least one of the coordinate data (hereinafter referred to as selected coordinate data) included in the selected line drawing data indicates a position in the end area 95 (S34). Coordinate data indicating the position in the end area 95 is stored in the flash memory 43 in advance. When all of the selected coordinate data indicates a position outside the end area 95 (S34: NO), the CPU 41 determines whether at least one of the selected coordinate data indicates any one of the plurality of target areas. (S35). Coordinate data indicating the positions of the plurality of target areas is stored in advance in the flash memory 43. When all of the selected coordinate data indicate all outer positions of the plurality of target areas (S35: NO), the CPU 41 returns the process to the process of S33.

  When at least one of the selected coordinate data indicates an inner position of any of the plurality of target areas (S35: YES), the CPU 41 selects a target area (at least one of the selected coordinate data indicates an inner position) Hereinafter, the specific target area is specified (S36). The CPU 41 specifies a group of target areas to which the specific target area belongs (S37). CPU41 performs the process after S41 demonstrated below for every group of target area to which a specific target area belongs. Thus, the specific area data indicating the specific target area among the plurality of area data indicating each of the plurality of target areas is stored in the RAM 42 as predetermined effective data or invalid data different from the effective data. Valid data and invalid data are data types of area data, respectively. In this embodiment, all area data is stored in advance in the RAM 42 as invalid data.

  The CPU 41 determines whether the length of one unit of line drawing indicated by the selected line drawing data is less than a predetermined reference length (S41). Specifically, the CPU 41 connects a plurality of positions indicated by the selected coordinate data with a straight line in the order of the times indicated by the associated plurality of time data. The CPU 41 calculates the length of one unit of line drawing by adding up the lengths of the straight lines. Reference data indicating the reference length is stored in advance in the flash memory 43. The CPU 41 compares the calculated length of the unit line drawing with the reference length indicated by the reference data. In this embodiment, the reference length is twice the diagonal length of the selection box. The length twice the length of the diagonal line of the selection box is the maximum length of one unit of line drawing composed of two line segments that can be written in the selection box. This reference length is particularly effective when it is assumed that one unit of line drawing composed of two line segments is written in the selection box, as in a check mark.

  By the process of S41, the CPU 41 can specify whether one unit of line drawing written is a check mark written for selecting an answer or a correction line written for correcting an answer. According to this, when the respondent performs the first step of the correction work in the questionnaire, it is only necessary to write one unit of line drawing longer than the reference length. That is, the respondent does not need to be aware of the shape of the correction line (one unit line drawing). The CPU 41 can execute different processes described below depending on whether the specified unit of line drawing is a check mark or a correction line.

  When the length of one unit of line drawing is less than the reference length (S41: YES), the CPU 41 stores, in the RAM 42, valid data indicating any one of a plurality of target areas for the specified group of target areas. Is determined (S42). When valid data indicating any of the plurality of target areas is not stored in the RAM 42 (S42: NO), the CPU 41 proceeds to the process of S44. When valid data indicating any of a plurality of target areas is stored in the RAM 42 (S42: YES), the CPU 41 stores valid data indicating any of the plurality of target areas already stored in the RAM 42. It is stored in the RAM 42 as invalid data (S43). The CPU 41 stores specific area data among the plurality of area data as valid data in the RAM 42 (S44). CPU41 returns a process to the process of S33.

  When the length of one unit of line drawing is equal to or longer than the reference length (S41: NO), the CPU 41 determines whether valid data indicating the specific target area is stored in the RAM 42 (S51). When the valid data indicating the specific target area is not stored in the RAM 42 (S51: NO), the CPU 41 returns the process to the process of S33. When the valid data indicating the specific target area is stored in the RAM 42 (S51: YES), the CPU 41 stores the valid data indicating the specific target area in the RAM 42 as invalid data (S52).

  The CPU 41 determines whether invalid data stored in the process of S43 is stored in the RAM 42 for the specified group of target areas (S53). When the invalid data stored in the process of S43 is not stored in the RAM 42 (S53: NO), the CPU 41 returns the process to the process of S53. When invalid data stored in the process of S43 is stored in the RAM 42 (S53: YES), the CPU 41 stores the invalid data stored latest in the RAM 42 in the process of S43 in the RAM 42 as valid data (S54). ). CPU41 returns a process to the process of S33.

  When at least one of the selected coordinate data indicates a position in the end area 95 (S34: YES), the CPU 41 executes an option confirmation process (S61). Specifically, the CPU 41 stores valid data in the flash memory 43. The CPU 41 deletes the answer file from the RAM 42. Thereby, one effective data is decided for every question number. For each question number, it is specified which of a plurality of options is an appropriate answer of the respondent. CPU41 returns a process to the process of S31.

For example, when a line drawing is already written in the selection box, the respondent writes one unit of line drawing near the periphery of the selection box. In the present embodiment, since the length A1 and the length A2 are longer than the length B1 and the length B2, respectively, the vicinity of the selection box is included in the region corresponding to the target region. One unit of line drawing 9L is written in an area corresponding to the target area 94C on the paper 123. Therefore, for the check mark 9L, the CPU 41 can determine that at least one of the coordinate data (selected coordinate data) included in the line drawing data indicates a position inside any of the plurality of target areas (S34: NO, S35: YES). The CPU 41 specifies a specific target area (target area 94C) and specifies a group of target areas 94 to which the specified specific target area belongs (S36, S37).

For the question number 54, the option 61C corresponding to the selection box 74C is specified as an appropriate answer from the respondent.

  As described above, when the length of one unit of line drawing is less than the reference length (S41: YES), the CPU 41 stores specific area data among a plurality of area data as valid data in the RAM 42 (S44). . On the other hand, when the length of one line drawing is equal to or longer than the reference length (S41: NO), the specific area data among the plurality of area data is stored in the RAM 42 as invalid data (S52). Different processing is executed according to the length of one unit of line drawing. Therefore, the CPU 41 can execute appropriate processing according to the line drawing data corresponding to at least one of the plurality of target areas.

  When the length of one line drawing is less than the reference length (S41: YES), the CPU 41 stores valid data in the RAM 42 (S43). In some cases, valid data is already stored in the RAM 42 (S42: YES). In this case, before storing valid data in the RAM 42, the CPU 41 stores valid data already stored in the RAM 42 as invalid data in the RAM 42 (S42). Therefore, the CPU 41 can specify one area data as valid data.

  For example, in a questionnaire, the respondent may write a check mark in the second selection box after writing a check mark in the first selection box. Thereafter, the respondent may write a correction line in the second selection box. In this case, the appropriate answer of the respondent is an option corresponding to the first selection box. In this example, by writing a check mark in the first selection box, the CPU 41 stores area data indicating the target area corresponding to the first selection box in the RAM 42 as valid data (S44). By writing a check mark in the second selection box, the CPU 41 stores valid data indicating the target area corresponding to the first selection box in the RAM 42 as invalid data (S43). The CPU 41 stores area data indicating the target area corresponding to the second selection box in the RAM 42 as valid data. By writing a correction line in the second selection box, the CPU 41 stores valid data indicating the target area (specific target area) corresponding to the second selection box in the RAM 42 as invalid data (S52). The CPU 41 stores the invalid data (invalid data indicating the target area corresponding to the first selection box) stored in the RAM 42 in the process of S43 among the invalid data stored in the RAM 42 as valid data in the RAM 42. (S54). Thus, the CPU 41 can specify the option corresponding to the first selection box as an appropriate answer from the respondent. That is, the CPU 41 can specify a selection box corresponding to an option that is an appropriate answer from the respondent.

  For example, when one unit of line drawing is written as in the examples of FIGS. 4 and 5, the area data indicating the target area 91B is stored as valid data when the processing after S33 is executed for the check mark 9C. Has been. In this case, it is assumed that the area data is not stored in the RAM 42 as valid data or invalid data for each group of target areas. In this case, when the processes after S33 are executed for the check mark 9D, the valid data indicating the target area 91B becomes invalid data, and the area data indicating the target area 92A becomes valid data. That is, the answer of the respondent regarding the question number 51 cannot be specified. In the present embodiment, the CPU 41 can store area data indicating each target area for each group of target areas in the RAM 42 as valid data or invalid data. Therefore, the CPU 41 can specify the answer of the respondent for each question number. Therefore, the user can provide a plurality of questions on one page of paper 123. For example, the CPU 41 can efficiently execute a questionnaire counting process.

  For example, line drawings such as check marks and correction lines may already be written in the selection box. In this case, since the area for writing a line drawing in the selection box is small, the respondent may write a unit of line drawing outside the selection box. In the present embodiment, the length A1 is longer than the length B1. The length A2 is longer than the length B2. That is, the shape of the target area is larger than the shape of the selection box. For this reason, even if a line drawing is written outside the selection box, the CPU 41 can execute the processing after S36 if it is located within the target area. That is, even when the respondent writes a unit of line drawing outside the selection box, the CPU 41 can determine whether the area data indicating the target area corresponding to the selection box is valid data or invalid data.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, a part of the second main process may be executed by the CPU 21. CPU21 may perform the process after S33, when an answer file is produced (S16). CPU21 may perform the process after S34, when writing is complete | finished (S13: YES). That is, the CPU 21 may execute the processing after S34 every time one unit of line drawing is written.

  The reference length is set twice as long as the diagonal line of the selection box. The circumference of a circle whose diameter is one side of the selection box may be set as the reference length. The circumference of a circle whose diameter is one side of the selection box is the maximum diameter of the circle that can be written in the selection box. For example, this reference length is particularly effective when it is assumed that a circle is written in the selection box. Another length may be set as the reference length. It is preferable to set, as a reference length, the maximum length that can be used to write a unit of line drawing in a shape that is supposed to be written in the selection box. For example, the shape of one unit of line drawing written in the selection box may be printed on the paper 111 and exemplified. The reference length may be changeable by the user.

  The selection box and the target area may have other shapes such as a circle and a rectangle. The end box 75 and end region 95 may also have other shapes. The selection box may have a different shape from the target area. The length A2 may be longer than the length B2, and the length A1 may be set equal to the length B1. This is because when respondents answer a questionnaire, if a line drawing has already been written in the selection box, the respondent often writes a check mark above or below the selection box.

  The sheet 123 may have only a group of selection boxes 71, for example. That is, a configuration in which one question answer is written on one page of paper 123 may be employed. In this case, the detection area 90 may have only a plurality of target areas 91A to 91C. The CPU 41 can omit the process of S37.

  In the above embodiment, one unit of line drawing is a line drawing written by a series of writings from the start to the end of the line drawing. One unit of line drawing may be a line drawing written until a predetermined time (for example, 1 second) elapses after the writing of the line drawing is started. For example, when the user writes a correction line, the core 31 may be temporarily separated from the paper 111 and a correction line may be formed by a plurality of line drawings. Even in this case, the CPU 41 can appropriately determine that the written line drawing is a correction line.

  The CPU 41 can omit the processes of S43, S53, and S54. The area data indicating the selection area corresponding to the selection box in which the check mark is written once is stored in the RAM 42 as valid data. The valid data stored in the RAM 42 is not stored in the RAM 42 as invalid data unless a correction line is written in a selection box in which a check mark is written. This is effective for a questionnaire in which a plurality of options can be selected.

  Instead of transmitting the answer file, the CPU 21 may transmit the line drawing data to the PC 19 every time one unit of line drawing is written. In this case, the CPU 41 may execute the processing after S34 for each line drawing data received from the PC 19. In the above embodiment, the CPU 41 stores data in the RAM 42 or the flash memory 43. The CPU 41 may store data in a storage device not shown. The method for detecting the position of the electronic pen 3 may be a method different from the above embodiment. For example, a known pen tablet or the like may be employed as an input device instead of the reading device 2.
