Description

  The present invention relates to a drawing data storage method using a digital pen, a transparent rewritable sheet, and a clear file.

  Conventionally, in drawing creation work for creating a drawing using a personal computer, the created drawing data is printed on paper and checked against the original drawing. When corrections were found at the time of confirmation, the drawing data was corrected on the personal computer, and when the corrections were completed, the work was repeated by printing on paper and checking. For this reason, if there are many corrections until completion, the paper must be printed over and over again, causing problems in terms of wasting paper and storage.

  Therefore, as a measure for solving such a problem, for example, a method using a rewritable sheet can be considered. This is because by using a rewritable sheet, if the printed drawing data is corrected, it can be corrected on a personal computer and the corrected drawing data can be rewritten to the rewritable sheet. However, when printing drawing data on a rewritable sheet, the base material of an ordinary rewritable sheet is opaque, so even if the rewritable sheet is superimposed on the original drawing, the original drawing cannot be seen through, and the printed drawing data There is a problem that it is not possible to confirm by checking the original map.

  On the other hand, in recent years, a rewritable sheet using a transparent material as a base material has been developed (see, for example, Patent Document 1 below). By using such a transparent type rewritable sheet, it is possible to collate with the printed drawing data if the original drawing is viewed through. However, on the contrary, since the base material is transparent, another problem arises that it becomes difficult to see the contents of the printed drawing data. In addition, even when using an opaque type or a transparent type rewritable sheet, it is impossible to save the entered information in association with the drawing data after writing the corrected portion in the drawing data by handwriting. There is also a problem.

JP 2002-59653 A

  The present invention has been made to solve such problems, and in drawing creation work, it is possible to save resources by printing drawing data created by a personal computer on a rewritable sheet without printing on paper. The drawing data printed on the rewritable sheet can be easily checked, and the drawing data printed on the rewritable sheet and the handwritten writing information can be associated with each other and saved as digital data. It is an object of the present invention to provide a drawing data storage method.

  In order to achieve the above object, the present invention is a drawing data storage method using a digital pen, a transparent rewritable sheet, and a clear file, and a dot pattern for position detection recognized by the digital pen on the surface side of the clear file Each side layer is printed on the back side, the drawing data is printed on a transparent rewritable sheet so that it can be rewritten, the page is recognized with a digital pen based on the dot pattern, and then the transparent rewritable sheet is sandwiched in the clear file. The information to be added to the drawing data printed on the rewritable sheet is written on the surface of the clear file containing the dot pattern so as to be rewritable with a digital pen, and the drawing data and the writing information are associated and stored as digital data. .

  In order to achieve the above object, the present invention is a drawing data storage method using a digital pen, a transparent rewritable sheet, and a clear file, and a dot pattern for position detection recognized by the digital pen on the surface side of the clear file The background layer is printed on the back side, drawing data and page sections are printed on a transparent rewritable sheet in a rewritable manner, and the page is recognized by a digital pen based on the dot pattern and page section, and then transparent to a clear file. Write the information to be added to the drawing data printed on the transparent rewritable sheet with the rewritable sheet sandwiched on the surface of the clear file containing the dot pattern so that it can be rewritten with a digital pen, and save the drawing data and the writing information in association with each other. It is characterized by doing.

  Here, terms used in the present invention are defined below.

  The digital pen means a pen-type input device that can read written information, convert it into digitized digital data, and store it. In the present invention, an exclusive Anoto pen developed by Swedish company Anoto can be used. In addition, in order to write in a rewritable manner with a digital pen, the ink of a digital pen is a reversible ink, for example, an ink that can be erased by heating, such as a thermal ink of a thermal pen, and an oily agent with a release agent for a whiteboard marker. Use ink that can be erased by wiping like ink.

  The transparent rewritable sheet is a recording medium that can be erased and rewritten after printing various information, and means a recording medium using a transparent material as a base material. The reason for using the transparent rewritable sheet is to superimpose the rewritable sheet on the original drawing so that the printed drawing data can be collated with the original drawing seen through. Examples of the transparent rewritable sheet that can be used in the present invention include a leuco dye type rewritable sheet using transparent PET as a substrate.

  The clear file may be formed by folding a sheet made of a synthetic resin or the like in at least half and sandwiching a transparent rewritable sheet therebetween. The clear file needs to use a transparent or translucent material so that the drawing data printed on the transparent rewritable sheet can be confirmed.

  The dot pattern for position detection represents an absolute coordinate for specifying the position on the clear file where the information written with the digital pen is a unique pattern made up of a large number of fine dots. In the present invention, an Anoto pattern corresponding to the above-mentioned Anoto type dedicated pen can be used.

  In the present invention, drawing data means computerized data that can be created and modified on a personal computer, and the file format of the data is not particularly limited, such as a dxf file, a dwg file, or a vsd file.

  The page classification is data necessary for recognizing a page such as a page number. The printing of page sections can be represented by, for example, a dot pattern, a bar code, a two-dimensional code, an OCR pattern, an OMR mark, or the like.

  In the drawing data storage method of the present invention, a transparent rewritable sheet is sandwiched between clear files to check the drawing data. At this time, in order to make the drawing data easy to see, the color of the transparent rewritable sheet and the background layer of the clear file are checked. It may be set so that the color of the color is complementary. The complementary color relationship is a relationship between two colors when the two colors are mixed at an appropriate ratio to become an achromatic color. For example, when the printing color of the transparent rewritable sheet is blue, the background layer of the clear file may be set to yellow, and when the printing color is red, the background layer may be set to blue-green.

  Further, in the drawing data storage method of the present invention, after storing digital data, the drawing data printed on the transparent rewritable sheet and the writing information written in the clear file including the dot pattern are deleted, and the transparent rewritable sheet and the dot are deleted. It is preferable to reuse a clear file with a pattern.

  In the drawing data saving method of the present invention, after saving digital data, the drawing data and page classification printed on the transparent rewritable sheet and the additional information written in the clear file containing the dot pattern are erased to be transparent. It is preferable to reuse a rewritable sheet and a clear file containing a dot pattern.

  According to the drawing data storage method of the present invention, the following effects can be obtained.

  When printing and checking drawing data created on a personal computer, paper resources can be abolished and transparent rewritable sheets and clear files can be reused to save resources and reduce costs in drawing creation work. .

  Because the rewritable sheet is transparent, you can check the printed drawing data against the original drawing that is visible through the watermark, and the background layer of the clear file will be in contrast, making it difficult to see the contents of the drawing data. The drawing data can be easily checked. In particular, when the printing color of the transparent rewritable sheet and the color of the background layer of the clear file are set in a complementary color relationship, the contrast between the two is emphasized, so that the contents of the printed drawing data can be seen more easily.

  Information that is handwritten on drawing data can be converted to digital data with a digital pen and immediately imported to a personal computer, reducing the time required for digitization and greatly improving the efficiency of drawing work. To do.

  The page classification can be recognized with a digital pen, and data can be stored in association between drawing data printed on a transparent rewritable sheet and information manually added to a clear file, eliminating data matching errors. At the same time, the data handling workability is excellent. In particular, when the page section is printed together with the drawing data, the dot pattern and the page section can be recognized, and the page can be recognized by collating both, thereby improving the reliability of the data.

  Since it is not necessary to copy the drawing data by hand in order to save the information added by hand, or to input it with a scanner to import it into a personal computer, information leakage can be prevented and security is improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory diagram showing the procedure of the drawing data storage method of the present invention, FIG. 2 is a sectional view showing the configuration of a clear file used in the method of the present invention, and FIG. 3 is an enlarged view showing a dot pattern printed on the clear file. 4 is a cross-sectional view showing the structure of a transparent rewritable sheet used in the method of the present invention, and FIG. 5 is a cross-sectional view showing the structure of a digital pen used in the present invention.

  As shown in FIG. 1, the drawing data storage method of the present invention uses a digital pen 10, a transparent rewritable sheet 20, and a clear file 30, and (A) printing a dot pattern and a background layer, (B) drawing data. The printing, (C) page recognition, (D) writing of writing information, (E) saving of data, (F) erasing of drawing data and writing information are performed. Therefore, the specific contents of each procedure will be described below.

(A) Printing a dot pattern and a background layer First, a dot pattern and a background layer are printed on a clear file.

  As shown in FIG. 2, the clear file 30 according to the present embodiment is formed by folding a transparent polypropylene sheet in half and sandwiching the transparent rewritable sheet 20 therebetween. A dot pattern 40 is printed on the front side of the clear file 30, and a background layer 50 is printed on the back side opposite thereto.

  Printing on the clear file 30 is performed using a printer 60 such as offset printing (printing is possible) as shown in FIG. That is, the ink is transferred from the ink roller 61 of the printer 60 to the blanket cylinder 63 through the plate cylinder 62, this ink is transferred to the clear file 30, the dot pattern 40 is printed on the front surface, and the background layer 50 is printed on the back surface. To do.

  The dot pattern 40 is a position detection marker for recognizing information written by the digital pen 10 and a page section. In this embodiment, an Anoto pattern is adopted as the dot pattern 40. As shown in FIG. 3, this Anoto pattern is a pattern in which a large number of fine dots 41, 41,... Are slightly shifted from intersections on the lattice at intervals of about 0.3 mm in either the upper, lower, left or right direction. is there. That is, a unique pattern made up of a total of 36 dots 41 of 6 × 6 (1.8 mm × 1.8 mm) represents the absolute coordinates on the clear file 30. Each dot 41 is printed with an infrared absorbing ink having heat resistance so as to absorb infrared light irradiated from the infrared camera of the digital pen 10. As the infrared absorbing ink, for example, an ink containing a carbon black pigment or an ink in which an infrared absorbing agent is added to an auxiliary agent can be used.

  The background layer 50 is provided to make it easy to confirm the drawing data printed on the transparent rewritable sheet 20. The background layer 50 is formed on the clear file 30 by solid printing or pattern printing with heat-resistant ultraviolet curable ink. In this embodiment, the color of the background layer 50 is white, but more preferably, the background layer 50 is set to have a complementary color relationship with the printing color of the transparent rewritable sheet 20. The reason is to increase the contrast between the color of the background layer 50 and the printing color of the transparent rewritable sheet 20 and make it easier to see the contents of the printed drawing data.

(B) Printing of drawing data Next, drawing data is printed on a transparent rewritable sheet.

  The transparent rewritable sheet 20 of the present embodiment is a leuco dye type rewritable sheet having transparency. As shown in FIG. 4, the rewritable sheet 20 is obtained by applying a thermosensitive coloring layer 22 to the surface of a base material 21 made of transparent PET. The thermosensitive coloring layer 22 is composed of a coloring agent 23 made of leuco dye and a phenolic compound. And the developer 24. When the thermosensitive coloring layer 22 is heated, the color former 23 and the developer 24 are melted to develop color, and when this is rapidly cooled, the color development state is fixed. On the other hand, the heat-sensitive color developing layer 22 is heated to melt the color former 23 and the color developer 24, and when they are gradually cooled, the color disappears.

  The drawing data D is computerized data that can be created and modified on the personal computer 80, and the file format of the data is not particularly limited, such as a dxf file, a dwg file, or a vsd file. Printing of the drawing data D on the transparent rewritable sheet 20 is performed using a thermal printer 70 as shown in FIG. That is, when the transparent rewritable sheet 20 is heated and rapidly cooled by the thermal head 71 of the thermal printer 70, the drawing data D is printed in a rewritable manner by the color of the thermosensitive coloring layer 22. The drawing data D created by the personal computer 80 is stored in the memory in the personal computer 80 corresponding to the page division data of the dot pattern 40.

  Although not shown, the page section may be printed simultaneously with the drawing data D. The page classification represents data necessary for page recognition such as a page number by a dot pattern, a bar code, a two-dimensional code, an OCR pattern, an OMR mark, and the like.

(C) Page Recognition Next, the page of the clear file is recognized with a digital pen.

  The digital pen 10 of the present embodiment is an Anoto pen corresponding to the Anoto pattern. As shown in FIG. 5, the digital pen 10 includes a case 11 in which a pen unit 12, a cartridge 13, an infrared camera 14, a processor 15, a memory 16, a communication unit 17, and a battery 18 are accommodated. Yes.

  The pen unit 12 writes writing information with ink filled in the cartridge 13. In order to write on the clear file 30 so as to be rewritable, a reversible ink is used. For example, ink that is erased by heating, such as thermal ink of a thermal pen, or ink that is erased by wiping off, such as oil-based ink containing a release agent for a whiteboard marker, can be used. In this embodiment, thermal ink is used so that it can be erased using the thermal head 71 of the thermal printer 70.

  The infrared camera 14 includes a light emitting unit that irradiates infrared light toward the clear file 30 from the opening at the tip of the case, and a light receiving unit that includes a CMOS sensor or the like that receives reflected light from the clear file 30. An infrared image around the unit 12 is taken.

  The processor 15 obtains binarized data from the infrared image taken by the infrared camera 14 according to the infrared absorption level, recognizes the handwriting of the pen unit 12 from the data, and stores the handwriting digital data in the memory 16 It is. The communication unit 17 performs data communication with an external device by Bluetooth (registered trademark) communication. The battery 18 is an internal power source composed of a lithium ion battery.

  The page recognition of the clear file 30 is performed by tracing the clear file 30 with the digital pen 10. That is, when a part of the clear file 30 is traced with the digital pen 10, an infrared image of the dot pattern 40 on the clear file 30 is taken by the infrared camera 14. At this time, the processor 15 recognizes the page section information of the clear file 30 specified by the coordinate value of the dot pattern 40 based on the captured infrared image. The page section data recognized by the processor 15 is stored in the memory 16.

  In the illustrated example, a plurality of clear files 30 paged by the dot pattern 40 are prepared for page recognition. However, when the drawing data D and the page classification are printed on the transparent rewritable sheet 20, Since the printed dot pattern 40 and the page classification can be recognized by the digital pen 10 and the two can be collated to recognize the page, the reliability of the data is improved.

(D) Writing of additional information Next, the additional information is written in a clear file with a digital pen.

  The writing information M is written with the ink of the digital pen 10. That is, the transparent rewritable sheet 20 is sandwiched between the clear files 30, and writing is performed from above the dot pattern 40 with the pen unit 12 of the digital pen 10 while viewing the contents of the drawing data D printed on the transparent rewritable sheet 20. Here, since the base 21 of the transparent rewritable sheet 20 is transparent, if the transparent rewritable sheet 20 is superimposed on the original drawing, the original drawing can be seen through, so the printed drawing data D and the original drawing are collated. be able to. At this time, the background layer 50 of the clear file 30 becomes a contrast so that the contents of the drawing data D are not easily seen. Therefore, the confirmation work of the drawing data D can be easily performed.

  Thus, when writing is performed with the digital pen 10, the writing information M is written in a rewritable manner with the thermal ink filled in the cartridge 13. In the example shown in the figure, the letters “Approve” are written as the additional information M, and the correction of the printed drawing data D is confirmed.

  Further, during the writing, the infrared camera 14 of the digital pen 10 continuously captures infrared images of the dot pattern 40 on the clear file 30. At this time, the processor 15 reads the position of the character specified by the coordinate value of the dot pattern 40 based on the captured infrared image and its movement locus, and what character is written on the clear file 30. Recognize the additional information M. The retouching information M recognized by the processor 15 is converted into digital data and stored in the memory 16 together with the page section data.

(E) Storage of data Next, the data is stored in a personal computer.

  Data transfer work from the digital pen 10 to the personal computer 80 can be performed using the communication function of the digital pen 10. That is, the communication unit 17 is built in the digital pen 10, and the page classification and the digital data of the writing information M stored in the memory 16 are transferred to the personal computer 80 by the wireless communication of the communication unit 17. Then, the transferred digital data is associated with the drawing data D stored in the memory of the personal computer 80 by using the page division data as a key. Thereby, the drawing data D and the writing information M can be stored in association with each other. The data transfer operation may be performed by connecting the digital pen 10 and the personal computer 80 with a wired connection such as a USB cable.

(F) Erasing drawing data and writing information Finally, the drawing data of the transparent rewritable sheet and the writing information of the clear file are deleted.

  If the data storage in the personal computer 80 is completed, the drawing data D printed on the transparent rewritable sheet 20 and the rewriting information M written on the clear file 30 may be erased. That is, when the transparent rewritable sheet 20 is heated and gradually cooled by the heat roller 72 of the thermal printer 70 or other erasing means (for example, a hot plate or a thermal head), the thermosensitive coloring layer 22 is decolored and the transparent rewritable sheet 20 is removed. The drawing data D printed on is erased. In addition, when the clear file 30 is heated by the heat roller 72 or the like, the thermal ink is decolored, so that the “approved” character of the writing information M written with the digital pen 10 can be erased. When oil-based ink containing a release agent is used for the ink of the digital pen 10, the writing information M written in the clear file 30 may be wiped off and deleted.

  Further, since the dot pattern 40 printed on the clear file 30 is made of heat-resistant infrared absorbing ink and the background layer 50 is made of heat-resistant ultraviolet curable ink, it can be heated by the heat roller 72 or the like. The dot pattern 40 and the background layer 50 are not erased. For this reason, since the dot pattern 40 and the background layer 50 remain in the clear file 30 after the writing information M is erased, it is not necessary to print the dot pattern 40 and the background layer 50 again as in (A) above. Therefore, once the dot pattern 40 and the background layer 50 are printed, the transparent rewritable sheet 20 and the clear file 30 can be reused. Thereafter, the drawing data storage process is performed according to the procedures (B) to (F). Can be executed.

  When the drawing data D and the page section are printed on the transparent rewritable sheet 20, the page section is deleted simultaneously with the deletion of the drawing data D.

  As described above, according to this drawing data storage method, the drawing data D and the additional information M are immediately stored as digital data in the personal computer 80 by using the digital pen 10, the transparent rewritable sheet 20, and the clear file 30. can do. For this reason, the work time at the time of digitizing the information written by handwriting is shortened, and the efficiency of drawing creation work is greatly improved. Further, since the digital data can be easily associated between the drawing data D and the additional information M, no data matching error occurs. Furthermore, since it is not necessary to copy the information by the copying machine or input it by the scanner in order to save the writing information M, information leakage can be prevented and the security is improved.

  In the above-described embodiment, an Anoto pen is used as the digital pen 10 and an Anoto pattern is used as the dot pattern 40. However, the present invention is not limited to this, and other combinations of digital pens and dot patterns may be adopted. Good. Further, although a leuco dye type rewritable sheet having transparency is used for the rewritable sheet 20, other reversible recording media can be used as long as they can be seen through and information can be rewritten. Furthermore, reversible inks other than thermal inks can be used for digital pen inks.
