Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, an outline of an electronic pen used as an input device in the system of the present invention will be described.

[Electronic pen]

FIG. 1 is a diagram schematically showing a usage pattern of the electronic pen, and FIG. 2 is a functional block diagram showing the structure of the electronic pen. As shown in FIG. 1, the electronic pen 10 is used in combination with the special paper 20 on which the dot pattern is printed. The electronic pen 10 has a pen tip portion 17 similar to that of a normal ink pen, and a user writes characters or the like on a special paper 20 like a normal ink pen.

As shown in FIG. 2, the electronic pen 10 includes a processor 11, a memory 12, a data communication unit 13, a battery 14, an LED 15, a camera 16, and a pressure sensor 18 inside the electronic pen 10. Further, the electronic pen 10 has an ink cartridge (not shown) or the like as a component similar to that of a normal ink pen.

The electronic pen 10 does not digitize the trajectory of the ink drawn on the special paper 20 by the pen tip portion 17, but digitizes the trajectory coordinates of the movement of the electronic pen 10 on the special paper 20. While the LED 15 illuminates the vicinity of the pen tip 17 on the special paper 20, the camera 16 reads the dot pattern printed on the special paper 20 and converts it into data. That is, the electronic pen 10 can acquire the stroke generated by the user moving the electronic pen 10 on the special paper 20 as image data or vector data.

The pressure sensor 18 detects the pressure applied to the pen tip 17 when the user writes characters or the like on the special paper with the electronic pen 10, that is, the writing pressure, and supplies the pressure to the processor 11. The processor 11 switches on / off the LED 15 and the camera 16 based on the pen pressure data given by the pressure sensor 18. That is, when the user writes characters or the like on the special paper 20 with the electronic pen 10, writing pressure is applied to the pen tip portion 17. Therefore, when a writing pressure equal to or higher than a predetermined value is detected, it is determined that the user has started the description, and the LED 15 and the camera 16 are operated.

The camera 16 reads the dot pattern on the dedicated paper 20 and supplies the pattern data to the processor 11. The processor 11 calculates the X / Y coordinates on the dedicated paper 20 from the supplied dot pattern.

The processor 11 acquires the pen pressure array data and the X / Y coordinate data while the user is described, and stores the data in the memory 12 in association with the time stamp (time information). Therefore, the data corresponding to the description contents of the user is stored in the memory 12 in chronological order. The capacity of the memory 12 can be, for example, about 1 Mbyte.

All the acquired data is held in the memory 12 until the transmission instruction is given by the user. Then, when the user gives a transmission instruction, the data communication unit 13 transmits the data in the memory 12 to the terminal device 25 within a predetermined distance from the electronic pen 10. Basically, once a transmission instruction is given, the electronic pen 10 transmits all the data stored in the memory 12 to the terminal device 25, so that the memory 12 is cleared. Therefore, if the user wants to transmit the same information to the terminal device 25 again after transmission, the user needs to write the information again on the dedicated paper 20. In this case, the user only has to trace the characters written with the ink pen on the special paper 20.

The electronic pen 10 itself does not have a function button such as a send button, and the transmission instruction and other instructions are given by the user checking the special box provided at a predetermined position on the special paper 20 with the electronic pen 10. Will be executed. A transmission instruction is associated with the position coordinates of the dedicated box in advance, and when the processor 11 receives the position coordinates of the dedicated box, it supplies the data in the memory 12 to the data communication unit 13 and transmits the data to the terminal device 25. To do. The electronic pen 10 can indicate the completion of data transmission by the vibration of the electronic pen.

The battery 14 is for supplying power to each element in the electronic pen 10. For example, the power of the electronic pen 10 itself can be turned on / off by a cap (not shown) of the electronic pen.

In this way, the electronic pen 10 has a function of acquiring coordinate data and pen pressure data corresponding to characters and the like described on the dedicated paper 20 by the user and transmitting them to a nearby terminal device 25. Since the pen tip 17 is a normal ink pen, the content described on the special paper 20 remains as the original original. That is, at the same time as describing the original paper, the contents can be digitized in real time in the form of coordinate data or the like.

According to the standard function of the electronic pen 10, the data obtained by the electronic pen 10 is, in principle, in the form of coordinate data or vector data, not text data. However, as a standard function, the electronic pen 10 has a function of converting only alphanumeric characters into text by writing in a dedicated area provided on the dedicated paper 20.

In addition, property information (pen information and pen owner information) regarding the pen itself and its owner can be stored in the electronic pen 10 and can be referred from the application. The pen information can hold the battery level, pen ID, pen manufacturer number, pen software version, subscription provider ID, and the like. In addition, as pen owner information, nationality, language, time zone, email address, free memory capacity, name, address, fax / telephone number, mobile phone number, etc. can be retained.

In the data communication unit 13 in the above example, the electronic pen 10 is transferred to the terminal device 25 by various methods such as wireless transmission of Bluetooth (registered trademark), wired transmission using a USB cable, and data transmission by contact with a terminal or the like. It is conceivable to transmit the data of.

Next, a method of acquiring X / Y coordinate data of the contents described by the user with an electronic pen will be described. As described above, a predetermined dot pattern is printed on the special paper 20. The camera 16 of the electronic pen 10 does not read the trajectory of the ink described on the special paper 20 by the user, but reads the dot pattern on the special paper 20. In fact, as shown in FIG. 1, the illumination area by the LED 15 and the shooting area of the camera 16 (located in the illumination area) are out of the positions where the pen tip 17 contacts the special paper 20.

The dot pattern is printed with a special ink containing carbon, and the camera 16 can recognize only the pattern with the special ink. Even if you print ruled lines or frames on the special paper with ink other than the special ink (which does not contain carbon), the electronic pen does not recognize them. Therefore, when creating forms such as various application forms using special paper, the input frame, ruled lines, cautionary notes, etc. are printed with ink other than the special ink.

In the dot pattern, as illustrated in FIG. 3, the position of each dot is associated with the data. In the example of FIG. 3, 2-bit information of 0 to 3 is displayed by shifting the dot position vertically and horizontally from the reference position of the grid (intersection of vertical and horizontal lines). The combination of the information expressed in this way determines the position coordinates on the special paper. As illustrated in Fig. 4 (a), 36 dots are arranged in a grid pattern within a range of 2 mm in length and width, and the array of data indicated by these dots (Fig. 4 (b)) is on the dedicated paper. It is associated with the position coordinates of. Therefore, when the camera 16 of the electronic pen 10 captures a dot pattern as shown in FIG. 4 (a), the processor 11 obtains the data array shown in FIG. 4 (b) based on the dot pattern data input from the camera 16. It is acquired and the position coordinates on the corresponding special paper (that is, where the dot pattern is on the special paper) are calculated in real time. The minimum unit for recognizing a dot pattern is 2 mm x 2 mm, and the camera 16 shoots about 100 times per second.

Next, the special paper will be described. Figure 5 shows an example of the structure of the special paper. As shown in the figure, the special paper 20 has a dot pattern 32 printed on the mount 30, and a design 34 such as a ruled line printed on the dot pattern 32. The mount 30 is usually paper, and the dot pattern 32 is printed with a special ink containing carbon as described above. In addition, the design 34 is printed with ordinary ink or the like. The dot pattern and the design may be printed at the same time, or either one may be printed first.

An example of design 34 is shown in FIG. FIG. 6 is an example of a certain application form 36, in which a plurality of entry fields 38 and an outbox 39 are printed. Although not clearly illustrated in FIG. 6 and details will be described later, the dot pattern is actually printed on the entire surface of the application form 36, and the entry fields 38 and the transmission box 39 are printed with ordinary ink on the entire surface of the application form 36. It is printed. The user may fill in the necessary items in each entry field 38 of the application form 36 by using the electronic pen 10 in the same manner as the conventional application form without being conscious of the dot pattern.

The area on the special paper 20 can be roughly divided into two types of areas. One is an entry area, which handles the description contents of the electronic pen 10 as information as it is. In the example of FIG. 6, a plurality of entry fields 38 correspond to this. The other is a functional element, and when the corresponding area is checked with the electronic pen 10, actions, instructions, etc. defined in advance for that area are executed. Outbox 39 in the example of FIG. 6 corresponds to this.

As described above, the transmission box 39 is used to give an instruction to transmit the data stored in the electronic pen 10 to the nearby terminal device 25. When the user puts a check in the outbox 39 with the electronic pen 10, the electronic pen 10 reads the dot pattern in the outbox. The pattern is associated with a transmission instruction, and the processor 11 in the electronic pen 10 issues a transmission command for the stored data in the memory 12 to the data communication unit 13.

Dot pattern assignment is usually done for each application (paper type). That is, the dot patterns in a certain application form do not overlap on one sheet of paper, but the same dot pattern is printed on the same application form. Therefore, when the user inputs necessary items with the electronic pen 10, it is possible to specify from the coordinate data on the application form which item of the application form the input item is for.

In this way, by printing a predetermined pattern on the special paper on which the dot pattern is printed, various application forms using the special paper can be created. The user fills in the necessary items in the usual way using the electronic pen 10, and the electronic data is automatically acquired.

In the above example, the dot pattern is printed on a special paper with carbon-containing ink, but it is also possible to print the dot pattern on ordinary paper using a printer and carbon-containing ink. Furthermore, the design on the special paper can also be formed by a printer instead of printing. When the dot pattern is formed on paper by a printer, it is possible to form a different dot pattern on each sheet. Therefore, it is possible to identify and distinguish each of these sheets by the difference in the formed dot patterns.

In this specification, the term "printing" is a concept that includes not only normal printing but also printing by a printer.

Next, the transmission process of the data acquired by the electronic pen will be described with reference to FIG. The data acquired by the electronic pen 10 is mainly data of items input by the user, but usually does not include information on where the service server to which the data is transmitted is. Instead, information that identifies the application or service related to the dedicated paper is included in the dot pattern on the dedicated paper, and that information is obtained from the dedicated paper during the user's input work. Therefore, the terminal device 25 that has received the input data from the electronic pen 10 first inquires the inquiry server 26 which service server 27 should send the data input to the dedicated paper. The inquiry server 26 has information on the corresponding service server for each dedicated paper, and in response to an inquiry from the terminal device 25, provides information (URL, etc.) on the service server 27 that provides services related to the dedicated paper. Answer to the terminal device 25. Then, the terminal device 25 transmits the entry data acquired from the electronic pen to the service server 27.

In the above example, the terminal device 25, the inquiry server 26, and the service server 27 are separately configured, but some or all of them can be configured as one device. In the present embodiment, the server described later also serves as the inquiry server 26 and the service server 27.

[Bookmark processing system]

Next, the bookmark processing system of the present invention will be described. Figure 7 shows the schematic configuration of the bookmark processing system 100. The bookmark processing system 100 shown in FIG. 7 corresponds to the information entered in the form by the user folding a part of the electronic pen form (hereinafter referred to as "notebook") and entering a check mark. It is possible to easily organize the electronic data to be generated according to the intention of the user and perform a predetermined process.

As shown in FIG. 7, the bookmark processing system 100 is configured by connecting the terminal device 25 and the server 5 through the network 2. Here, one preferred example of network 2 is the Internet. The terminal device 25 is a terminal capable of exchanging data via a network 2 such as a PC or a mobile phone used by a user. The server 5 is connected to the entry information database (hereinafter referred to as "DB") 7.

First, I will give an overview of how to organize the entered information in this system. Note 3 was created as the above-mentioned special paper, and is composed of a plurality of pages as shown in FIG. In Note 3, page number 70, which is a serial number uniquely assigned to a plurality of pages, and a bookmark area corresponding to a part where a user bends and writes a check mark are set.

As shown in FIGS. 8 (a) and 8 (b), the note 3 is configured such that the left side of the two-page spread is an odd page and the right side is an even page, and the note 3 as a paper medium and the note concerned. In order to check that both the electronic data corresponding to the information entered in 3 have a bookmark effect, fold the upper corner of each page and fold it to cover the exposed area with an electronic pen. It is necessary to fill in the checkmark using 10. Here, the bookmark effect in Note 3 as a paper medium means an effect that a predetermined page can be easily opened by actually folding a part of the page. Further, the bookmark effect in the electronic data corresponding to the entered information means an effect that the data entered on a predetermined page can be easily extracted from the entered information and processed.

The user uses the electronic pen 10 to fill in the predetermined contents in the notebook 3. Then, on the page where the bookmark effect is to be generated, fold the upper corner of the page and put a check mark in the bookmark area exposed on the surface by folding. The electronic pen 10 acquires stroke data corresponding to the written contents, temporarily stores the stroke data in the memory 12 in the electronic pen 10, and then transmits the stroke data to the terminal device 25. The terminal device 25 receives the stroke data from the electronic pen 10 and transmits it to the server 5 through the network 2. The server 5 acquires the stroke data as entry information indicating the contents entered by the user for the note 3, and stores the stroke data in the entry information DB 7 in association with the page number of each page.

Further, the server 5 determines whether or not the entry information has a stroke including the coordinates where the bookmark area is located on the dot pattern of the note 3. If there is a stroke that includes the coordinates where the bookmark area is located, that is, if the bookmark area is marked, the server 5 will check which page of note 3 corresponds to the bookmark area based on the entry information. Identify if the mark was entered. Then, the bookmark information indicating that the bookmark effect is generated is stored in the entry information DB7 in association with the page number of the specified page. Further, the server 5 extracts the entry information of the page to which the bookmark information is associated from the entry information DB7, and performs a predetermined process. The contents of the characters and the like entered in the note 3 in the present embodiment are stored as image data in the entry information DB7 using the page number as a key.

In this way, when the user folds a part of the note 3 using the electronic pen 10 and fills in the check mark, the server 5 uses the paper medium, the note 3, and the entry information written in the note 3. The bookmark effect can be generated for both of the electronic data corresponding to.

Note that note 3 shown in FIG. 8 does not include an outbox for convenience, but note 3 is also provided with an outbox having the same function as the outbox 39 shown in FIG.

[Note]

Next, note 3 will be described. In the system of the present invention, Note 3 as shown in FIG. 8 is created as the above-mentioned dedicated paper. That is, as illustrated in FIG. 5, a predetermined dot pattern 32 is printed on the mount 30, and a predetermined page number, a ruled line, or the like is printed on the predetermined dot pattern 32. As mentioned earlier, the dot pattern 32 is printed with carbon-containing ink so that the electronic pen 10 can recognize it. On the other hand, since the design 34 such as the page number and the ruled line is printed with normal (carbon-free) ink, the electronic pen 10 does not recognize it.

FIG. 8A is a diagram showing a state in which the pages of the page numbers 01 and 02 of Note 3 are opened. Further, FIG. 8B is a diagram showing a state in which the pages of the page numbers 03 and 04 of Note 3 are opened.

If you want to create a bookmark effect for the page with page number "01", the user can fold the upper corner to coordinates 80a, 80b and 80c, as shown on the left side of Figure 8 (a). The enclosed bookmark area 50 is exposed to the surface. Then, the user uses the electronic pen 10 to write a check mark in the bookmark area 50. In this way, the bookmark area 50 corresponding to the page with the page number "01" is a part of the dot pattern constituting the previous page.

On the other hand, if it is desired to generate a bookmark effect on the page with page number "02", the user can fold the upper corner to surface the bookmark area 51 as shown on the right side of Fig. 8 (a). Expose to. Then, the user writes a check mark in the bookmark area 51 using the electronic pen 10. As described above, the bookmark area 51 corresponding to the page with the page number "02" is a part of the dot pattern constituting the next page. That is, the bookmark area 51 is a part of the dot pattern constituting the page of the next page, page number "03", as shown by shading on the left side of FIG. 8 (b).

When the user wants to generate a bookmark effect on the page with page number "03", the user exposes the bookmark area 52 to the surface by folding the upper corner as shown on the left side of Fig. 8 (b). Let me. Then, the user uses the electronic pen 10 to write a check mark in the bookmark area 52. In this way, the bookmark area 52 corresponding to the page with page number "03" is a dot pattern constituting the page with page number "02", which is the previous page, as shown by diagonal lines on the right side of FIG. 8 (a). Is part of.

In this way, the page on which the bookmark effect is to be generated and the page on which the bookmark area exposed on the surface by folding does not always match. Therefore, in the present invention, the page on which the bookmark effect occurs and the coordinates of the bookmark area corresponding to the page are stored in advance in association with each other by the bookmark coordinate table described later.

[server]

Next, the server 5 will be described in detail. FIG. 9 shows the internal configuration of the bookmark processing system 100, especially the server 5. As shown in the figure, the server 5 has a bookmark processing program 501, an entry information acquisition function 502, an image data extraction function 503, a page coordinate table 504, a bookmark page identification function 505, a bookmark coordinate table 506, a storage function 507, and a bookmark reference function 508. It is composed of. Each function is realized by executing a program prepared in advance by the CPU of the server 5.

The bookmark processing program 501 refers to the page coordinate table 504 based on the entry information acquired from the electronic pen 10, and stores the corresponding entry information in the entry information DB7 using the page number of each page of the note 3 as a key. It is a program to do. In addition, the bookmark processing program 501 identifies and identifies the corresponding page when a check mark is entered in the bookmark area by referring to the bookmark coordinate table 506 based on the entry information acquired from the electronic pen 10.

That is, as shown in FIG. 11, the entry information DB7 stores the corresponding image data and bookmark information using the page number as a key.

The bookmark reference function 508 extracts the image data corresponding to the page number in which the bookmark information is stored in the entry information DB7 and sends it to the terminal device 25 to display only the image data of the page on which the bookmark effect is generated. This is a function to be presented to the user. In other words, the bookmark reference function 508 is a function that extracts the image data corresponding to the page number in which the bookmark information item of the entry information DB is "Yes" and presents it to the user.

In the present embodiment, the bookmark reference function 508 extracts the image data corresponding to the page number in which the bookmark information is stored in the entry information DB7 and presents the image data to the user. It is not limited, and arbitrary processing can be performed on the extracted image data. This is because an object of the present invention is to organize electronic data corresponding to the information entered on a predetermined page of Note 3 according to the intention of the user, depending on whether or not the bookmark effect is generated.

[Bookmark processing]

Next, the bookmark processing executed by the bookmark processing system 100 will be described. FIG. 12 is a flowchart of bookmark processing. The user first uses the electronic pen 10 to write a predetermined character on any page of the notebook 3 (step S1). Here, the predetermined character is, for example, the content of a meeting or a lecture. If you want to create a bookmark effect because you have completed the entry on any page of Note 3 and have entered important content on that page and need to review it later, the user folds and folds the top corner of the page. By doing so, use the electronic pen 10 to write a check mark in the bookmark area exposed on the surface (step S2). Then, the user writes a check mark in the transmission box on the note 3 and transmits the entry information to the server 5 via the terminal device 25 (step S3).

If you fill in multiple pages and want to create a bookmark effect on two of them, for example, the user can fold each upper corner of the two pages to cover each bookmark area exposed on the surface. Fill in the check mark. Then, by entering a check mark in the transmission box on the note 3, the entry information is transmitted to the server 5 via the terminal device 25.

The server 5 acquires the entry information and extracts the image data for each page by referring to the page coordinate table based on the entry information (step S7). Then, the server 5 stores the corresponding image data in the entry information DB7 using the page number of each page as a key (step S8). Further, the server 5 identifies the page corresponding to the bookmark area in which the check mark is entered by referring to the bookmark coordinate table based on the entry information (step S9). That is, the page on which the bookmark effect has occurred is specified. Then, the server 5 stores the bookmark information in the entry information DB7 using the page number of the specified page as a key (step S10). Next, the server 5 extracts only the image data corresponding to the page on which the bookmark effect is generated from the entry information DB 7 and presents it to the user by transmitting it to the terminal device 25 (step S11). As a result, the bookmark processing is completed.

As described above, according to the present invention, the user can fold a part of the page constituting the notebook 3 and enter a check mark to generate a bookmark effect on the information entered on the page. it can. That is, it is possible to easily extract and organize only specific information in which the bookmark effect is generated from the entry information entered on the plurality of pages, or to perform a predetermined process.

In the present embodiment, in the bookmark processing, the entry information is collectively transmitted to the server 5 even after filling in a plurality of pages of the note 3, but the present invention is limited to this. Instead, the entry information may be sent to the server 5 every time one page is filled.

Further, in the present embodiment, the page coordinate table and the bookmark coordinate table are separate tables as shown in FIGS. 10A and 10B, but the present invention is not limited to this, and the page number is used. It is also possible to have one table as a key.

Further, in the present embodiment, the bookmark area is set at the upper corner of the page as shown in FIG. 8, but the present invention is not limited to this, and the bookmark area is arranged at an arbitrary position such as the lower corner. Can be done.
