  In the following, when one writer writes by hand on the transparent coating member 20 and finishes the writing, the next person executes the reading process and the clean-up conversion process without performing the next writing, It is assumed that the writing conversion is performed while referring to the recognition pattern relating to the character characteristics of the one writer, and thermal writing is performed on the rewritable paper 2.

  The control means 15 provided in the board main body 11 of the writing board device 1 periodically monitors whether the user identification information receiving means 16 receives the fingerprint data, and the transparent coating member 20 on the rewritable paper 2. When the writer who wants to write on touches the input means 34 of the writing instrument 3 with a predetermined finger (for example, forefinger) and inputs fingerprint data, the fingerprint data is written from the user identification information transmitting means 36 of the writing instrument 3. When the fingerprint data is received by the user identification information receiving means 16 of the board main body 11 by wireless transmission to the user identification information receiving means 16 of the board main body 11 of the board device 1 (step B1), the fingerprint data is used. Stored in the person identification information storage means 17 (step B1).

  Then, the writer uses the writing tool 3 to add a colorant to the transparent coating member 20 on the rewritable paper 2 of the writing board device 1 and write the coloring agent (step B3). When the writing is completed, the writing board device 1 A clear text conversion instruction button provided on the board main body 11 is pressed to instruct a clear text conversion for handwritten writing (step B4), whereby a reading process for handwritten writing and a clear text conversion process are executed. It should be noted that the operation means related to the instructions for converting the clean copy may be provided in association with the keys on the keyboard 83 of the personal computer 80.

  Then, when the conversion of the clear text is instructed, the moving body 4 starts to move from the origin position to the end position by the step control of the stepping motor 41 of the moving means 40, and the reading means 5 mounted on the moving body 4 reads. The colorant writing on the transparent coating member 20 is optically read by the part 51, and the read colorant write is erased by the erasing part 61 of the colorant erasing means 6 immediately after this reading is performed. (Step B5), the read image data (image data in a bitmap format, etc.) read by the reading means 5 from the transmission / reception means 19 of the writing board device 1 and the use immediately before the clear text conversion instruction is given in Step B4. The writer's fingerprint data that has been sent is transmitted to the transmission / reception means 99 of the apparatus main body 81 of the personal computer 80 (step B6). .

  The apparatus main body 81 of the personal computer 80 monitors the reception of the read image data and the fingerprint data from the writing board apparatus 1 in a state where the corresponding application including the recognition means 96 is activated. When the read image data and the fingerprint data are received from the writing board device 1 (step B7), the fingerprint data is collated by the recognition pattern storage means 98 (step B8), and the recognition pattern storage means 98 stores the fingerprint data. If the writer-specific recognition pattern stored in association with the data is registered (step B9), the dedicated recognition pattern is selected (step B10) and stored in the recognition pattern storage means 98. If the writer-specific recognition pattern stored in association with the fingerprint data is not registered (step B9), The quasi-recognition pattern is selected (step B11), and the recognition means 96 recognizes the characters and / or figures of the read image data based on the writer-specific recognition pattern or standard recognition pattern (step B12). The clear text conversion data based on the character code data and / or graphic code data is generated, and the generated clear text conversion data is displayed on the display 82 of the personal computer 80 (step B13).

  If the recognition pattern dedicated to the writer stored in association with the fingerprint data of the writer is not registered in the recognition pattern storage means 98 in step B9, the recognition pattern dedicated to the writer is used. It may be configured to prompt a new registration of a pattern. In this configuration, whether or not to newly register a recognition pattern dedicated to the writer is displayed on the display 82 of the personal computer 80. If a dedicated recognition pattern is newly registered, the dedicated recognition pattern is selected. If a new recognition pattern dedicated to the writer is not newly registered, a standard recognition pattern is selected, and the following recognition is performed. Done. The new registration of the recognition pattern will be described later.

  Then, the writer confirms the clean copy conversion data displayed on the display 82, and if there is an erroneously converted character and / or figure, it is corrected or added by operating a key on the keyboard 83 while looking at the display 82. Is input (step B14), updated to the clean text conversion data corrected to correct characters and / or figures, and displayed on the display 82 (step B13).

  On the other hand, if there is no erroneously converted character and / or figure, input of correction, addition, etc. is not performed (step B14), and a predetermined key (cleared text conversion confirmation key) on the keyboard 83 is operated to convert the clear text. The data is confirmed (step B15), and the copy conversion data confirmed thereby is transmitted as image data in a bitmap format or the like from the transmission / reception means 99 of the apparatus main body 81 of the personal computer 80 to the transmission / reception means 19 of the writing board device 1. (Step B16).

  When the transmission / reception means 19 of the writing board apparatus 1 receives the clear text conversion data obtained by converting the read image data read by the reading means 5 into clear text (step B17), the moving body 4 moves the stepping motor 41 of the moving means 40. While moving from the end point position to the origin position (when the moving body 4 is controlled to be returned to the origin position after reading by the reading means 5 in step B5), it is moved from the end position to the end position. , Of the heat source heads 71, 71,... Of the thermal writing erasing means 7 mounted on the moving body 4, the heat source heads 71, 71,. Heat is written on the rewritable paper 2 by generating heat in the temperature region 1 (step B18).

  The thermal writing by the thermal writing erasing means 7 is configured so that the thermal writing erasing means 7 starts thermal writing after receiving all the conversion data of all areas to be written on the rewritable paper 2 once. Alternatively, the thermal writing may be performed while receiving the clear conversion data in a small unit, and the reception of the clear conversion data and the thermal writing by the thermal writing erasing unit 7 may be performed in parallel.

  As described above, the handwritten characters and / or figures written on the transparent coating member 20 of the writing board device 1 are rewritten in a predetermined font on the rewritable paper 2 and are easy to read.

  The clean copy conversion data can be stored in the storage means of the apparatus main body 81 of the personal computer 80 or the storage means of the board main body 11 of the writing board device 1, and after erasing the thermal writing once, as necessary. It is possible to call up and write again on the rewritable paper 2 to redisplay.

  Then, in order to erase the characters and / or figures thermally written on the rewritable paper 2, the thermal erasure processing instruction button provided on the board body 11 of the writing board device 1 is pressed to instruct the thermal erasure processing ( In step B19), the thermal erasing process by the thermal writing / erasing means 7 is thereby executed. It should be noted that the operating means related to the instruction of the thermal erasing process by the thermal writing / erasing means 7 may be provided in correspondence with the keys on the keyboard 83 of the personal computer 80.

  Then, according to the instruction of the thermal erasing process, the moving body 4 is moved from the origin position to the end position (step B18 by thermal writing by the thermal writing erasing means 7 in step B18) by the step control of the stepping motor 41 of the moving means 40. In the case of controlling to move from the origin position to the end position and stand by at the end position, the thermal writing erasing means 7 mounted on the movable body 4 is moved while moving from the end position to the origin position). Of the multiple heat source heads 71, 71,..., The heat source heads 71, 71,... Corresponding to the region (for example, the upper half region or the entire region) thermally written on the rewritable paper 2 are set to the second temperature. The area is heated to erase the thermal writing on the rewritable paper 2 (step B20).

Next, an example of the new registration of the recognition pattern will be described.
First, the writer writes hiragana (50 sounds) on the transparent coating member 20 on the rewritable paper 2 with the writing instrument 3. The hiragana 50 syllabary may be written in a lump or may be written in several units such as a line or a line. When the writing is finished, when a predetermined key (cleaned text conversion instruction key) on the keyboard 83 of the personal computer 80 is operated to instruct conversion of the written text, the reading means 5 scans and reads the written data, and the converted text is converted. Done and displayed on the display 82.

  At this time, there are hiragana characters that have not been correctly converted to clear text. In many cases, the characters are not correctly converted so that there is a defect in the characters. In this case, the keyboard 83 is operated while looking at the display 82 to correct the characters. As described above, when the hiragana written by the writer himself is associated with the corresponding hiragana code data, and all of the hiragana that has not been correctly converted into the written form is finished, a predetermined key on the keyboard 83 is obtained. By operating the key (clean copy conversion confirmation key), a recognition pattern in which the hiragana written by the writer himself is associated with the corresponding hiragana code data is created, and the writer writes it to the recognition pattern storage means 98. Are stored in association with the fingerprint data.

  As described above, for all hiragana, a recognition pattern in which the hiragana written by the writer himself is associated with the corresponding hiragana code data is created, and the writer's name is stored in the recognition pattern storage means 98. It is stored in association with fingerprint data. Similarly, katakana, uppercase and lowercase letters of the alphabet, numbers, frequently used symbols (such as “¥”, “%”, “?”, Etc.), radicals of kanji (“tree” bias, “word” bias, etc.) Also, a recognition pattern in which a character / and / or figure written by the writer himself and the corresponding character code data / and / or figure code data are associated with each other is created. It is created and stored in the recognition pattern storage means 98 in association with the writer's fingerprint data. As described above, the writer's recognition pattern is newly registered in association with the writer's fingerprint data.

  In the above, two examples of image drawing by the image drawing apparatus have been described. However, when the writer writes on the transparent coating member 20 on the rewritable paper 2, the following security is added to make it an unauthorized person. May be configured such that writing cannot be performed.

  When fingerprint data is input by touching the input means 34 of the writing instrument 3 with a predetermined finger (for example, forefinger), the fingerprint data is transferred from the user identification information transmitting means 36 of the writing instrument 3 to the user of the board body 11 of the writing board device 1. When the fingerprint data is received by the user identification information receiving means 16 of the board body 11 by wireless transmission to the identification information receiving means 16, the received user identification information is received by the verification means 18 as the user identification information storage means 17. Is matched with any one of the user identification information stored in advance, and if it matches, the process proceeds to step A1 in the first embodiment, and step in the second embodiment. Proceeding to B3, the following flow is executed.

The recognition step for generating the conversion data and the clean copy conversion data generated in the recognition step A display step for visual display, an edit acceptance step for accepting edits to the image displayed in the display step, an update step for updating the copy conversion data in accordance with the edit contents input in the edit acceptance step, A generation step for generating thermal writing data for thermal writing on the rewritable paper based on the clean copy conversion data updated in the updating step, and a coloring agent writing for erasing the image written in the coloring agent writing step An erasing step; a thermal writing step for performing thermal writing on the rewritable paper based on the thermal writing data generated in the generating step; and a thermal erasing step for thermally erasing the image thermally written in the thermal writing step. In the third embodiment, personal authentication is performed and the following flow is configured.

  In the following, when one writer writes by hand on the transparent coating member 20 and finishes the writing, the next person can also write, and here, the reading process and the clear conversion process are executed. Then, it is assumed that the writing conversion is performed while referring to the recognition pattern relating to the character characteristics of each writer, and thermal writing is performed on the rewritable paper 2.

  The control means 15 provided in the board main body 11 of the writing board device 1 periodically monitors whether the user identification information receiving means 16 receives the fingerprint data, and the transparent coating member 20 on the rewritable paper 2. When the writer who wants to write on touches the input means 34 of the writing instrument 3 with a predetermined finger (for example, forefinger) and inputs fingerprint data, the fingerprint data is written from the user identification information transmitting means 36 of the writing instrument 3. When the fingerprint data is received by the user identification information receiving means 16 of the board body 11 by wireless transmission to the user identification information receiving means 16 of the board main body 11 of the board device 1 (step E1), the fingerprint data is used. Stored in the person identification information storage means 17 (step E2).

Then, when the writer uses the writing instrument 3 to write the colorant by adding the colorant to the transparent coating member 20 on the rewritable paper 2 of the writing board device 1 (step E3), the coordinate detecting means 10 writes the colorant. The position coordinates are detected (step E4), and image data (image data such as a bitmap format) is generated (step E5). Whenever the writing is performed in the coordinate detection means 10, the position coordinate of the writing is detected to generate image data, and the image data and the fingerprint data of the writer who wrote the image data are transmitted and received by the transmission / reception means 19 of the writing board device 1. To the transmission / reception means 99 of the apparatus main body 81 of the personal computer 80 (step E6).
Here, it is assumed that the reception of fingerprint data in step E1 and the transmission of image data and fingerprint data in step E6 may be performed once for a series of writing.

  Furthermore, when writing is performed on the transparent coating member 20 of the rewritable paper 2, the flow from step E1 to step E6 is repeated.

  In this embodiment, every time there is a series of writing on the transparent coating member 20 of the rewritable paper 2, the coordinate position of the writing is recognized by the coordinate detecting means 10, and the series of writing is performed in the image data storage means 13. The image data to be written and the fingerprint data of the writer of the image data are stored in association with each other.

  That is, when the writer X inputs fingerprint data to the input means 34 of the writing instrument 3 and writes on the transparent coating member 20 of the rewritable paper 2, the coordinate position of the writing is recognized by the coordinate detecting means 10. The image data storage means 13 is configured to store the written image data and the writer's fingerprint data of the image data in association with each other. Thus, until the fingerprint data of the writer X is input to the input means 34 of the writing instrument 3 and the fingerprint data other than the writer X is input to the input means 34 of the writing instrument 3, the writing is performed during this period. The writing is performed by the writer X, and the image data of the writing detected by the coordinate detecting means 10 is stored in association with the fingerprint data of the writer X, so that who wrote to which coordinate position (area). It is configured to be recognized. In the transmission in step E6, the correspondence between the image data written on the transparent coating member 20 of the rewritable paper 2 and the fingerprint data of the writer (writer) of the image data (which region is which writer) The image data stored in the image data storage means 95 of the apparatus main body 81 of the personal computer 80, and the image data written on the transparent coating member 20 of the rewritable paper 2 in the clean-sheet conversion process described later. For each writer who writes, the clear conversion is executed while referring to the writer's own recognition pattern (standard recognition pattern for writer who has not registered the writer's exclusive recognition pattern). It is configured.

  Then, when the writing of the rewritable paper 2 to the transparent coating member 20 is completed for one paragraph, the writing content confirmation instruction button provided on the board body 11 of the writing board device 1 is pressed to write the writing on the transparent coating member 20 of the rewritable paper 2. An instruction to confirm the content to be stored is instructed (step E7), whereby a writing content confirmation command is transmitted from the transmission / reception means 19 of the writing board device 1 to the transmission / reception means 99 of the apparatus body 81 of the personal computer 80 (step E8). It should be noted that the operation means related to the written content confirmation instruction may be provided in association with the key on the keyboard 83 of the personal computer 80.

Next, an example of the new registration of the recognition pattern will be described.
First, the writer writes hiragana (50 sounds) on the transparent coating member 20 on the rewritable paper 2 with the writing instrument 3. The hiragana 50 syllabary may be written in a lump or may be written in several units such as a line or a line. The position coordinates of this handwritten writing are detected by the image detecting means 10, and when a predetermined key on the keyboard 83 of the personal computer 80 (cleaned text conversion instruction key) is operated to instruct conversion of the written text, Is displayed on the display 82.

  At this time, there are hiragana characters that have not been correctly converted to clear text. In many cases, the characters are not correctly converted so that there is a defect in the characters. In this case, the keyboard 83 is operated while looking at the display 82 to correct the characters. As described above, when the hiragana written by the writer himself is associated with the corresponding hiragana code data, and all of the hiragana that has not been correctly converted into the written form is finished, a predetermined key on the keyboard 83 is obtained. By operating the key (clean copy conversion confirmation key), a recognition pattern in which the hiragana written by the writer himself is associated with the corresponding hiragana code data is created, and the writer writes it to the recognition pattern storage means 98. Are stored in association with the fingerprint data.

  As described above, for all hiragana, a recognition pattern in which the hiragana written by the writer himself is associated with the corresponding hiragana code data is created, and the writer's name is stored in the recognition pattern storage means 98. It is stored in association with fingerprint data. Similarly, katakana, uppercase and lowercase letters of the alphabet, numbers, frequently used symbols (such as “¥”, “%”, “?”, Etc.), radicals of kanji (“tree” bias, “word” bias, etc.) Also, a recognition pattern in which a character / and / or figure written by the writer himself and the corresponding character code data / and / or figure code data are associated with each other is created. It is created and stored in the recognition pattern storage means 98 in association with the writer's fingerprint data. As described above, the writer's recognition pattern is newly registered in association with the writer's fingerprint data.

  In the above, three examples of image drawing by the image drawing apparatus have been described.
