Below, the case where a line drawing is written is demonstrated. The line drawing includes characters, numerical values, symbols, figures, and the like. The reading device 2 acquires the position of the electronic pen 3 in the writing process. The reading device 2 creates stroke data based on the acquired position. The stroke data includes at least a plurality of coordinate data indicating each of a plurality of positions on the line drawing written by the electronic pen 3. For this reason, each of the plurality of coordinate data indicates a locus of movement of the electronic pen 3 when a line drawing is written by the electronic pen 3. The reading device 2 can transmit the created stroke data to the smartphone 19. When the smartphone 19 receives the stroke data, the smartphone 19 displays an image corresponding to the received stroke data on the display 192. Thus, the user can visually recognize a line drawing having the same shape as the line drawing written on the paper medium 100 with the electronic pen 3 via the display 192. Further, the user can save stroke data indicating a line drawing written on the paper medium 100 with the electronic pen 3 in the reading device 2 and the smartphone 19.

  The reading device 2 has a rectangular thin plate shape. The reading device 2 includes a placement unit 2A on the front surface and an LED 5 on the upper end. A sensor substrate 7 (see FIG. 2), which will be described later, is disposed on the rear side of the mounting portion 2A. The paper medium 100 is detachably mounted on the placement unit 2A. The paper medium 100 includes a plurality of sheets 111 with upper end portions bound. Specific examples of the paper medium 100 include inspection tables for various facilities. The format indicating the layout of characters, line segments, etc. printed in advance on each of the plurality of sheets 111 may be different on each of the plurality of sheets 111. An inspection item is given as a specific example of characters printed in advance. As a specific example of a line segment printed in advance, a rectangular frame line indicating an entry field is given. The paper medium 100 is mounted in a state in which the paper medium 100 is positioned on the placement portion 2A by a double-sided tape, an adhesive resin film, or the like. The user can use the electronic pen 3 to write a line drawing on the paper 111 arranged at the outermost part among the plurality of papers 111 of the paper medium 100. Also, the user changes the page of the topmost sheet of paper to be written with the electronic pen 3 among the plurality of papers 111 to the next page by turning over the topmost sheet.

  The plurality of sheets 111 of the paper medium 100 is not limited to the case where the upper end is bound, and any of the left end, the right end, and the lower end may be bound.

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

  The coil 32 is held between the core body 31 and the capacitor 33 while being wound around the ink storage portion 36. The capacitor 33 is fixed inside the electronic pen 3 by the substrate 34. A capacitor 35 is mounted on the substrate 34. The capacitors 33 and 35 are connected in parallel to the coil 32 and constitute a known resonance (tuning) circuit. An unillustrated switch is provided behind the core body 31.

The reading device 2 includes a main board 20, a sensor control board 28, a sensor board 7, an input unit 25, and an LED 5. The main board 20 includes a CPU 21, a RAM 22, a flash ROM 23, and a wireless communication unit 24. The sensor control board 28 includes an ASIC 28A. The RAM 22, the flash ROM 23, the wireless communication unit 24, the input unit 25, the LED 5, and the ASIC 28A are electrically connected to the CPU 21. The sensor substrate 7 is electrically connected to the ASIC 28A.

  The CPU 21 controls the reading device 2. The RAM 22 temporarily stores various data such as calculation data. The flash ROM 23 stores a program executed by the CPU 21 to control the reading device 2. The flash ROM 23 stores a format table. In the format table, the medium ID, the number of pages, and the layout data are associated with each other. The medium ID is identification information indicating the type of the paper medium 100. The number of pages indicates the total number of pages of the plurality of sheets 111 included in the paper medium 100 indicated by the corresponding medium ID. The layout data is data that can specify the format of each of the plurality of sheets 111 of the paper medium 100 indicated by the corresponding medium ID for each page. More specifically, the layout data includes a position corresponding to each frame area of the date field 51, the name field 52, and the update check box 54 (see FIG. 3), which will be described later, in the placement unit 2A. Data that can be specified is included. Further, the layout data includes data (hereinafter referred to as “item data”) that can specify the contents of each of the plurality of inspection items included in the inspection item column 53. Further, the layout data includes data that can specify the corresponding position in the frame area of the check box that is included in the inspection item column 53 and is associated with each of the plurality of inspection items, in the placement unit 2A. Is included. Hereinafter, the positions corresponding to the frame areas of the check boxes included in the date field 51, the name field 52, the update check box 54, and the check item field 53 in the placement unit 2A are simply “ The position of the check box included in the date column 51, the name column 52, the update check box 54, and the check item column 53 ".

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

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

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

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

<Outline of Paper Medium 100, Usage Method>
With reference to FIG. 3, an outline of a paper medium 102 that is an example of the paper medium 100 will be described.

Each of the ten pages of paper 112 is provided with a title (number of pages) 50, a date column 51, a name column 52, and an update check box 54 as a common format. The title (number of pages) 50 is a character string indicating “check table (X / 10)” (X is a page number). The date column 51 is a rectangular frame for writing the date. The name column 52 is a rectangular frame for writing the name of the writer. The update check box 54 is a check box provided at the lower right of each of the 10 pages of paper 112. Of the ten pages of paper 112, the update check box 54 of the paper 112A except the paper 112J of the last page is associated with the character string “next page”, and the update check box 54 of the paper 112J is displayed. On the other hand, a character string “end” is associated.

  Each of the ten pages of paper 112 is provided with a different inspection item column 53 for each page. In the inspection item column 53, a plurality of inspection items and check boxes are listed. The inspection item column 53 is different for each of the plurality of sheets 112.

  The paper medium 102 is used by an inspector corresponding to each of the ten pages of paper 112 to inspect equipment according to the inspection items. Specifically, it is as follows. An inspector (hereinafter referred to as a “first inspector”) corresponding to the first page paper 112 </ b> A uses the electronic pen 3 to place the date page 51 in a state where the first page paper 112 </ b> A is arranged on the outermost part. The date “2015/2/1” is written, and the name “Taro Yamada” is written in the name column 52. The first inspector inspects the equipment based on the plurality of inspection items in the inspection item column 53A. The first inspector writes check marks in order with the electronic pen 3 in the check boxes corresponding to the confirmed check items among the check boxes in the check item column 53A.

  When the inspection corresponding to the plurality of inspection items in the inspection item column 53A of the paper 112A is completed, the first inspector writes a check mark in the update check box 54 with the electronic pen 3. A check mark is written in the update check box 54 in order to notify the reading device 2 that the inspection based on the paper 112A for the first page has been completed. In addition, the check mark for the update check box 54 is written so that the paper 112A on the first page is loaded and the paper placed on the outermost part is placed in order to start the inspection based on the paper 112B on the second page. This is performed to notify the reading device 2 that the first page 112A is updated to the second page 112B.

  When the CPU 21 of the reading apparatus 2 determines that the electronic pen 3 has written in the update check box 54 of the first page 112A, the date field 51, the name field 52, and the check item fields 53 include check boxes. The position is acquired based on the layout data of the format table stored in the flash ROM 23. The CPU 21 acquires stroke data corresponding to the line drawing written at the positions of the date column 51 and the name column 52. The CPU 201 checks the check items “1.1”, “1.2”, “1.3”, “1.4”, “1” corresponding to the check box in which the check mark is written out of the check boxes included in the check item column 53. .5 ”is specified based on the layout data of the format table stored in the flash ROM 23. The CPU 201 associates the stroke data of the date and name with the item data of the inspection item in which the check mark is written, and stores it in a predetermined area (hereinafter referred to as “data buffer”) of the flash ROM 23.

  Next, an inspector (hereinafter referred to as a “second inspector”) corresponding to the second page of paper 112B turns over the first page of paper 112A and places the second page of paper 112B in the outermost portion. . Thus, in the present embodiment, it is assumed that ten pages of paper 112 of the paper medium 102 are used while being paged one page at a time starting from the first page. In the above, instead of the second inspector, the first inspector may pick up the paper 112A for the first page.

  Similar to the first inspector, the second inspector writes the date “2015/2/1” in the date column 51 of the paper 112B arranged on the outermost portion with the electronic pen 3, and the name “52/2/1” in the name column 52. Written “Jiro Suzuki”. The second inspector writes a check mark with the electronic pen 3 in the check box corresponding to the confirmed check item among the plurality of check boxes included in the check item column 53. The second inspector writes a check mark with the electronic pen 3 in the update check box 54 when the inspection corresponding to the plurality of inspection items included in the inspection item column 53 of the paper 112B is completed. The CPU 21 associates the date and name stroke data and the item data of the inspection items “2.1”, “2.2”, “2.3”, and “2.5” in which the check mark is written, and stores them in the data buffer. To do.

  In the same procedure as described above, writing is performed with the electronic pen 3 for each of the paper 112 for 10 pages. Each time the check mark is written in the update check box 54, the CPU 21 associates the stroke data of the date and name and the item data of the inspection item in which the check mark is written, and stores them in the data buffer.

  When the CPU 21 stores the stroke data and the item data in the data buffer in association with the number of pages of the layout table stored in the flash ROM 23, the inspection items corresponding to all of the ten pages of the paper 112 are all inspected. Is determined. When the CPU 21 receives the request data from the smartphone 19 in this state, the CPU 21 transmits the stroke data and the item data stored in the data buffer to the smartphone 19 via the wireless communication unit 24.

  When the smartphone 19 receives the stroke data and the item data, the smartphone 19 displays the date, name, and inspection item on the display 192 for each of the ten sheets of paper 112 of the paper medium 102 based on the stroke data and the item data. . Specifically, for example, the person in charge of equipment inspection can confirm the state of equipment inspection by visually checking the date, name, and inspection items displayed on the smartphone 19.

<Main processing>
The main process in the first embodiment will be described with reference to FIG. Hereinafter, the case where the paper medium 102 of FIG. 3 is used will be described in detail by taking as an example an example. When the CPU 21 detects an operation for turning on the power of the reading device 2 via the input unit 25, the CPU 21 starts the main process by executing the program stored in the flash ROM 23. After turning on the power of the reading device 2, the user mounts the paper medium 102 (see FIG. 3) on the placement unit 2A (see FIG. 1). The user performs an operation for inputting the type of the loaded paper medium 102 via the input unit 25.

  When detecting an operation via the input unit 25, the CPU 21 acquires a medium ID corresponding to the input type (S11). The CPU 21 refers to the format table stored in the flash ROM 23, and acquires the number of pages (= “10”) associated with the acquired medium ID and layout data (S13). The CPU 21 sets “1” in the variable n (S15). The variable n indicates the number of pages of the paper 112 arranged at the outermost part among the plurality of papers 112. The CPU 21 clears the data buffer (S15). The CPU 21 extracts layout data corresponding to the nth page of the paper 112, that is, the paper 112 arranged in the outermost portion, from the layout data acquired by the process of S13 (S17).

  The CPU 21 determines whether or not a line drawing is written by the electronic pen 3 depending on whether the coordinate data output from the ASIC 28A is detected (S19). When the coordinate data from the ASC 28 is not detected, the CPU 21 determines that the line drawing is not written by the electronic pen 3 (S19: NO). In this case, the CPU 21 returns the process to S19. The CPU 21 continues to determine whether the line drawing has been written. 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 (S19: YES). In this case, the CPU 21 associates the coordinate data output from the ASIC 28 </ b> A with the time data indicating the time when the coordinate data is detected, and stores it in the RAM 22. CPU21 repeats the process which memorize | stores coordinate data and time data in RAM22 until writing with the electronic pen 3 is complete | finished.

  CPU21 specifies the position of the update check box 54 (refer FIG. 3) based on the layout data acquired by the process of S13, when writing with the electronic pen 3 is complete | finished. The CPU 21 determines whether or not a line drawing (check mark) is written in the update check box 54 by determining whether the position indicated by the coordinate data stored in the RAM 22 is included in the position of the update check box 54 (S21). ). When the position indicated by the coordinate data is not included in the position of the update check box 54, the CPU 21 determines that no line drawing is written in the update check box 54 (S21: NO). CPU21 advances a process to S25.

  CPU21 specifies the position of the date column 51 (refer FIG. 3) and the name column 52 (refer FIG. 3) based on the layout data acquired by the process of S13. When the position indicated by the coordinate data stored in the RAM 22 is included in the date column 51, the CPU 21 stores the position in the RAM 22 as part of the stroke data indicating the date of the n-th sheet 112 (see FIG. 3). The stored coordinate data and time data are stored in the data buffer (S25). When the position indicated by the coordinate data stored in the RAM 22 is included in the position of the name field 52 (see FIG. 3), the CPU 21 stores the position in the RAM 22 as a part of the stroke data indicating the name of the paper 112 on the nth page. The stored coordinate data and time data are stored in the data buffer (S25). CPU21 is based on the position shown by the coordinate data memorize | stored in RAM22, when the position shown by the coordinate data memorize | stored in RAM22 is contained in the position of the check box contained in the inspection item column 53 (refer FIG. 3). The item data of the inspection item corresponding to the check box is specified. The CPU 21 stores the identified item data in the data buffer as item data corresponding to the n-th page paper 112 (S25). The CPU 21 clears the RAM 22 and returns the process to S19.

  On the other hand, when the position indicated by the coordinate data is included in the position of the update check box 54, the CPU 21 determines that a line drawing (check mark) has been written in the update check box 54 (S21: YES). The CPU 21 updates the variable n by adding “1” (S23). The CPU 21 determines whether the updated variable n is larger than the number of pages (= “10”) acquired by the process of S13 (S27). When the updated variable n is equal to or smaller than the number of pages acquired by the process of S13 (S27: NO), the CPU 21 performs writing with the electronic pen 3 on all of the ten sheets of paper 112 of the paper medium 102. Judge that it is not. In this case, the CPU 21 returns the process to S17. Based on the updated variable n, the CPU 21 extracts layout data corresponding to the n-th sheet 112, that is, the topmost sheet 112 (S17), and repeats the process.

  On the other hand, when the updated variable n is larger than the number of pages acquired by the process of S13 (S27: YES), the CPU 21 uses the electronic pen 3 for all 10 pages of the paper 112 of the paper medium 102. It is determined that writing has been performed. CPU21 advances a process to S29.

  CPU21 determines whether the request data transmitted from the smart phone 19 was received (S29).

The CPU 21 transmits the stroke data and the item data extracted for each sheet 112 of the first to “n−1” pages to the smartphone 19 (S31). The CPU 21 ends the main process.

<Main functions and effects of the first embodiment>
As described above, in the first embodiment, the CPU 21 of the reading device 2 acquires coordinate data indicating the position on the line drawing written with the electronic pen 3 on the paper medium 102 on which the plurality of sheets 112 are bound ( S19). The CPU 21 detects stroke data including the coordinate data acquired from the ASIC 28A after detecting writing to the update check box 54 (S21: YES) and then detecting writing to the update check box 54 (S21: YES). Is stored in the data buffer in association with the item data included in the layout data of the paper 112 arranged in the topmost portion, in other words, the paper 112 of the nth page (S25). As described above, the CPU 21 can specify the item data corresponding to the sheet 112 arranged in the outermost part depending on whether or not the item data is written in the update check box 54 and store the item data in the data buffer in association with the stroke data.

  Further, the CPU 21 writes on the paper 112 arranged on the outermost part, that is, on the electronic pen 3 based on whether the writing is written in the update check box 54 provided at a position common to the plurality of papers 112 of the paper medium 102. The paper 112 that can be printed is identified. For this reason, there is no need to provide a check box or the like for individually specifying the plurality of sheets 112 of the paper medium 102 in each of the plurality of sheets 112. Accordingly, a sufficient area for providing the date column 51, the name column 52, and the inspection item column 53 can be secured in each of the plurality of sheets 112. Further, the CPU 21 can store the stroke data when the electronic pen 3 is written on a plurality of papers 112 in the data buffer in association with the item data corresponding to the written paper 112.

  When the CPU 21 determines that the writing operation has been performed with the electronic pen 3 approaching the position corresponding to the frame area of the update check box 54 in the placement unit 2A (S21: YES), the outermost part It is determined that the first sheet 112 has been updated to the next sheet 112. As a result, a portion excluding the update check box 54 in each of the plurality of sheets 112 of the sheet medium 102 can be secured as an area for acquiring stroke data. Therefore, a larger area for acquiring the stroke data can be secured on each of the plurality of sheets 112.

  Layout data is stored in the format table stored in the flash ROM 23. The layout data includes item data that can specify the contents of each of the plurality of inspection items included in the inspection item column 53. For this reason, the CPU 21 checks the check data corresponding to the written check box among the stroke data indicating the date and name written on each of the plurality of sheets 112 and the check items included in the check item column 53 of the sheet 112. The item data indicating the item can be associated and stored in the data buffer (S25).

Second Embodiment
A second embodiment of the present invention will be described with reference to FIGS. Note that the system overview (see FIG. 1) and the electrical configuration (see FIG. 2) are the same as those in the first embodiment, and a description thereof will be omitted. An outline of a paper medium 103 that is an example of the paper medium 100 will be described with reference to FIG. The paper medium 103 includes a plurality of sheets 113 (113A, 113B,... 113J). The difference between the plurality of sheets 113 and the plurality of sheets 112 (see FIG. 3) is that the update check box 54 (see FIG. 3) is not provided. Other formats (title (number of pages) 50, date column 51, name column 52, inspection item column 53) are the same as those of the plurality of sheets 112.

  The main process in the second embodiment will be described with reference to FIG. The same processes as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. The CPU 21 extracts layout data corresponding to the nth page of the paper 111, that is, the topmost paper 112 from the layout data acquired by the process of S13 (S17). The CPU 21 counts the total number of inspection items indicated by the item data included in the layout data extracted by the process of S17 (S41). The CPU 21 initializes the variable m stored in the RAM 22 by setting “0” (S41). The variable m indicates the total number of inspection items corresponding to the check box in which the line drawing is written in the inspection item column 53 of the paper 113 for one page.

  When the coordinate data is output from the ASIC 28A, the CPU 21 determines that the line drawing is written by the electronic pen 3 (S19: YES). The CPU 21 associates the coordinate data output from the ASIC 28A with the time data and stores them in the RAM 22. CPU21 repeats the process which memorize | stores coordinate data and time data in RAM22 until writing with the electronic pen 3 is complete | finished. When the writing with the electronic pen 3 is completed, the CPU 21 specifies the position of the check box included in the inspection item column 53 (see FIG. 5) based on the layout data acquired by the process of S13. CPU21 determines whether the position shown by the coordinate data memorize | stored in RAM22 is contained in the position of the check box contained in the inspection item column 53 (refer FIG. 3) (S43). If the CPU 21 determines that the position indicated by the coordinate data is not included in the position of the check box included in the inspection item column 53 (see FIG. 3) (S43: NO), the process proceeds to S25.

  On the other hand, when the position indicated by the coordinate data is included in the position of the check box included in the inspection item column 53 (see FIG. 3) (S43: YES), the CPU 21 draws a line drawing on the check box included in the inspection item column 53. Is determined to be written. The CPU 21 adds and updates “1” to the variable m stored in the RAM 22 in order to count the number of inspection items corresponding to the check box in which the line drawing is written (S45). CPU21 determines whether the variable m is more than the total number of the inspection items calculated by the process of S41 (S47). When determining that the variable m is smaller than the total number of inspection items (S47: NO), the CPU 21 returns the process to S19. On the other hand, if the CPU 21 determines that the variable m is equal to or greater than the total number of inspection items (S47: YES), the process proceeds to S23.

<Main functions and effects of the second embodiment>
As described above, in the second embodiment, the CPU 21 determines that the total number of line drawings written in the check boxes included in the inspection item column 53 is equal to or greater than the total number of inspection items included in the inspection item column 53 ( S47: YES), it is determined that the topmost sheet 113 of the plurality of sheets 113 of the paper medium 103 is updated to the sheet 113 of the next page. The reason for this is that all the inspection items on the top sheet 113 are checked, and all the inspection items are checked by the user, so the page to be written on the paper medium 103 is: This is because the possibility of updating to the next page is high. Therefore, even when the update check box 54 (see FIG. 3) is not provided on the paper 112, the CPU 21 identifies the topmost paper 113 that can be written and extracts the item data, and associates it with the stroke data in the data buffer. Can remember. Accordingly, it is possible to secure a larger area for providing the date column 51, the name column 52, and the inspection item column 53 on each of the plurality of sheets 113.

<Third Embodiment>
A third embodiment of the present invention will be described with reference to FIGS. With reference to FIG. 7, the electrical configuration of the reading device 2 in the third embodiment will be described. The difference from the electrical configuration of the reading device 2 in the first embodiment (see FIG. 2) is that a tag reader 26 is provided. Unlike the first embodiment, the electronic pen 3 is provided with an RFID tag. The tag reader 26 can detect the RFID tag and read the ID stored in the RFID tag. The tag reader 26 is electrically connected to the CPU 21. In the format table stored in the flash ROM 23, a plurality of IDs are associated in addition to the medium ID, the number of pages, and the layout data. The plurality of IDs indicate IDs stored in RFID tags provided in the electronic pen 3 possessed by each of a plurality of users who may use the paper medium 100 identified by the corresponding medium ID. Hereinafter, each of the plurality of IDs stored in the format table is referred to as “first identification information”, and the ID stored in the RFID tag is referred to as “second identification information”.

  With reference to FIG. 8, the main process in 3rd Embodiment is demonstrated. The same processes as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. The CPU 21 refers to the format table stored in the flash ROM 23, and acquires the number of pages, layout data, and a plurality of first identification information associated with the medium ID acquired by the process of S11 (S51). The CPU 21 sets “1” in the variable n (S15). The CPU 21 clears the data buffer (S15).

  The CPU 21 determines whether the RFID provided on the electronic pen 3 has been detected via the tag reader 26 (S53). When it is determined that the RFID is not detected (S53: NO), the CPU 21 returns the process to S53. The CPU 21 continuously monitors whether the RFID is detected. When it is determined that the RFID has been detected (S53: YES), the CPU 21 acquires the second identification information stored in the RFID (S55). The CPU 21 determines whether or not the plurality of first identification information acquired by the process of S51 includes the first identification information that matches the second identification information acquired by the process of S55 (S57). When it is determined that the first identification information that matches the second identification information is not included (S57: NO), the CPU 21 causes the LED 5 to blink. This notifies that the authentication has failed (S59). The CPU 21 returns the process to S53.

  On the other hand, when the plurality of first identification information acquired by the process of S51 includes the first identification information that matches the second identification information acquired by the process of S55 (S57: YES), the CPU 21 performs RFID. It is determined that tag authentication is successful. The CPU 21 extracts layout data corresponding to the nth page of the paper 112 from the layout data acquired by the process of S51 (S17). CPU21 advances a process to S19 (refer FIG. 9). Since the processing from S19 to S31 is the same as that of the first embodiment, description thereof is omitted.

<Main functions and effects of the third embodiment>
As described above, in the third embodiment, the CPU 21 matches the second identification information acquired from the RFID tag provided on the electronic pen 3 with the plurality of first identification information stored in the format table. It is determined whether identification information is included (S57). When it is determined that the first identification information that matches the second identification information is included (S57: YES), the CPU 21 extracts layout data corresponding to the nth page of the paper 112 (S17). In this case, when the CPU 21 writes with the electronic pen 3 having the RFID tag in which the second identification information that matches any of the plurality of first identification information stored in advance in the format table is written, the stroke data and The item data can be associated and stored in the data buffer. Therefore, since the CPU 21 can limit the electronic pen 3 on which the line drawing that is the basis of the stroke data stored in the data buffer is written, the stroke data is stored in the data buffer when the unspecified electronic pen 3 is used. Can be suppressed.

  In the third embodiment, order information indicating the order may be further associated with each of the plurality of pieces of first identification information stored in the format table. Specifically, the order information may be one or more natural numbers (1, 2, 3,...). The CPU 21 obtains the first identification information associated with the order information “n” among the plurality of first identification information obtained by the process of S51 and the second identification information obtained by the process of S55. It may be determined whether or not matches (S57). When the CPU 21 determines that the first identification information associated with the order information “n” and the second identification information do not match (S57: NO), the CPU 21 may proceed to the process of S59 and blink the LED 5. On the other hand, if the CPU 21 determines that the first identification information associated with the order information “n” matches the second identification information (S57: YES), the CPU 21 proceeds to the process of S17 and acquires the layout acquired by the process of S51. Of the data, layout data corresponding to the nth page paper 112 may be extracted (S17).

  If the CPU 21 determines that the writing operation has been performed with the electronic pen 3 approaching the position corresponding to the frame area of the update check box 54 in the placement unit 2A (S21: YES), the variable n Is updated (S23). Therefore, every time the line drawing is checked in the update check box 54, the CPU 21 updates the first identification information extracted from the plurality of first identification information stored in the format table based on the order information. It can be determined whether it matches the identification information. Therefore, when the CPU 21 detects the second identification information from the RFID tag in a predetermined order based on the order information, the CPU 21 can associate the stroke data with the item data and store them in the data buffer.

<Fourth embodiment>
A fourth embodiment of the present invention will be described with reference to FIGS. With reference to FIG. 9, an outline of a paper medium 104 that is an example of the paper medium 100 will be described. The paper medium 104 includes a plurality of sheets 114 (114A, 114B,... 114J). The difference between the plurality of sheets 114 and the plurality of sheets 112 (see FIG. 3) is that a code field 55 is newly provided as a common format. The code field 55 is a rectangular frame for writing a code for identifying the user. In the case of FIG. 9, “TM”, “ZS”, and “HI” are written in the code fields 55 of the sheets 114A, 114B, and 114J. Other formats (title (number of pages) 50, date column 51, name column 52, inspection item column 53, update check box 54) are the same as those of the plurality of sheets 112.

  In the format table stored in the flash ROM 23, a plurality of codes are associated in addition to the medium ID, the number of pages, and the layout data. The plurality of codes are information for identifying each of a plurality of users who may use the paper medium 100 identified by the corresponding medium ID. Hereinafter, each of the plurality of codes stored in the format table is referred to as “third identification information”, and the code written in the code column 55 is referred to as “fourth identification information”.

  The main processing in the fourth embodiment will be described with reference to FIGS. The same processes as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. The CPU 21 refers to the format table stored in the flash ROM 23, and acquires the number of pages, layout data, and a plurality of third identification information associated with the medium ID acquired by the process of S11 (S61). The CPU 21 sets “1” in the variable n (S15). The CPU 21 clears the data buffer (S15).

  The CPU 21 determines whether or not a line drawing has been written by the electronic pen 3 depending on whether the coordinate data output from the ASIC 28A has been detected (S63). When the coordinate data from the ASC 28 is not detected, the CPU 21 determines that a line drawing is not written with the electronic pen 3 (S63: NO). In this case, the CPU 21 returns the process to S63. The CPU 21 continues to determine whether the line drawing has been written. 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 (S63: YES). In this case, the CPU 21 associates the coordinate data output from the ASIC 28A with the time data indicating the time when the coordinate data is detected, and stores it in the RAM 22 as stroke data (S65). CPU21 repeats the process which memorize | stores coordinate data and time data in RAM22 until the state by which writing with the electronic pen 3 was complete | finished more than predetermined time (S65). Thus, when a code is written in the code field 55 (see FIG. 9), all coordinate data and time data corresponding to the written code are stored in the RAM 22.

  CPU21 specifies the position of the code | cord | chord column 55 (refer FIG. 9) based on the layout data acquired by the process of S61, when the state where the writing by the electronic pen 3 was complete | finished more than predetermined time. The CPU 21 determines whether the code is written in the code field by determining whether the position indicated by the coordinate data stored in the RAM 22 is included in the position of the code field 55 (S67). When the position indicated by the coordinate data is not included in the position of the code column 55, the CPU 21 determines that the code is not written in the code column 55 (S67: NO). CPU21 returns a process to S63.

  When the position indicated by the coordinate data is included in the position of the code column 55, the CPU 21 determines that the code is written in the code column 55 (S67: YES). The CPU 21 specifies the line segment written by the electronic pen 3 by connecting the position indicated by the coordinate data stored in the RAM 22 in the order of the time indicated by the time data. The PCU 21 specifies a written code as the fourth identification information by executing a known character recognition process on the specified line segment (S69).

  The CPU 21 determines whether or not the plurality of third identification information acquired by the process of S61 includes the third identification information that matches the fourth identification information specified by the process of S69 (S71). When it is determined that the third identification information that matches the fourth identification information is not included (S71: NO), the CPU 21 causes the LED 5 to blink. This notifies that the authentication has failed (S73). The CPU 21 returns the process to S63. On the other hand, when the CPU 21 determines that the plurality of third identification information acquired by the process of S61 includes the third identification information that matches the fourth identification information acquired by the process of S69 (S71: YES) ), The layout data corresponding to the paper 112 of the nth page is extracted from the layout data acquired by the process of S61 (S17). CPU21 advances a process to S19 (refer FIG. 11).

  The processes from S19 to S31 in FIG. 11 are the same as those of the first embodiment except for the process of S27. In the process of S27, when the updated variable n is equal to or smaller than the number of pages acquired by the process of S61 (S27: NO), the CPU 21 applies the electronic pen to all of the 10 sheets of paper 112 on the paper medium 104. It is determined that writing by 3 is not performed. In this case, the CPU 21 returns the process to S63 (see FIG. 10).

<Main functions and effects of the fourth embodiment>
As described above, in the fourth embodiment, the CPU 21 adds the third identification information that matches the fourth identification information written in the code field 55 by the electronic pen 3 to the plurality of third identification information stored in the format table. It is determined whether information is included (S71). If the CPU 21 determines that the third identification information that matches the fourth identification information is included (S71: YES), the CPU 21 extracts layout data corresponding to the nth page of the paper 112 (S17). In this case, when the fourth identification information that matches any of the plurality of third identification information stored in advance in the format table is written in the code column 55, the CPU 21 associates the stroke data and the item data with the data buffer. Can remember. Therefore, since the CPU 21 can limit the code of the user who has written the line drawing that is the basis of the stroke data stored in the data buffer, the stroke data is stored in the data buffer when an unspecified user writes using the electronic pen 3. Can be suppressed.

<Modification>
The present invention is not limited to the above embodiment, and various modifications can be made. In the above, the stroke data includes coordinate data and time data. Here, the coordinate data may be an absolute coordinate system with a predetermined position as a reference point, or a relative coordinate system with reference to coordinate data corresponding to the previous time data. For example, when the paper medium 100 is used for purposes other than the inspection table, the CPU 21 stores data related to the format of the paper 111 of the nth page and different from the item data in the data buffer in association with the stroke. Also good. Specifically, for example, data indicating line drawings (partition lines, figures, characters, numbers, etc.) printed in advance on the paper 111 may be included in the layout data instead of the item data. The CPU 21 may store these data in the data buffer in association with the stroke data.

  When it is determined that the line drawing has been written in the update check box 54 (S21: YES), the CPU 21 adds “1” to the variable n and updates it (S23). On the other hand, the CPU 21 may perform the determination process of S21 by another method and add “1” to the variable n when the condition is satisfied. For example, the CPU 21 may continuously detect the ID stored in the RFID provided in the electronic pen 3 by the tag reader 26. When the detected ID changes, the CPU 21 determines that the condition is satisfied by the process of S21 (S21: YES), and may add “1” to the variable n. For example, when the CPU 21 detects that a code is written in the code field 55, the CPU 21 may determine that the condition is satisfied by the process of S21 (S21: YES), and add “1” to the variable n. . When the line drawing written in the update check box 54 is a predetermined character, mark or the like, the CPU 21 determines that the condition is satisfied by the processing of S21 (S21: YES), and adds “1” to the variable n. Also good.

  The electronic pen 3 may not be provided with a switch. In this case, the ASIC 28 </ b> A can detect that the coil 32 of the electronic pen 3 has approached the sensor substrate 7. Then, when the electronic pen 3 comes close to the position of the update check box 54, the CPU 21 may determine that the condition is satisfied by the process of S21 (S21: YES) and add “1” to the variable n.

  In the second embodiment, the CPU 21 may specify the shape of the line drawing written at the position of the check box included in the inspection item column 53. When the specified shape satisfies the condition, the CPU 21 may determine that a line drawing (check mark) has been written in the check box included in the inspection item column 53. Then, the CPU 21 may determine whether the number of written line drawings is equal to or greater than the total number of inspection items.

  In the third embodiment, the CPU 21 includes, in the plurality of first identification information stored in the format table, the first identification information that matches the second identification information stored in the RFID tag provided in the electronic pen 3. If it is included, layout data corresponding to the topmost sheet 112 is extracted (S17). On the other hand, the first identification information stored in the format table may be one. The same second identification information as the first identification information may be stored in each of the plurality of RFID tags provided in the plurality of electronic pens 3.

  The CPU 21 may simultaneously execute the processes of S51 to S59 in the third embodiment and S61 to S73 in the fourth embodiment. That is, the CPU 21 includes first identification information that matches the second identification information stored in the RFID tag provided in the electronic pen 3 in the plurality of first identification information stored in the format table, and When the third identification information stored in the format table includes the third identification information that matches the fourth identification information written in the code field 55 by the electronic pen 3, the n-th page paper 112 is used. Layout data corresponding to may be extracted.
