  In the case of a book or the like (hereinafter referred to as a “physical book”) that is a printed matter having a physical entity, page reference based on a table of contents or index, or partial random reference by interposing a bag or the like is possible to some extent. However, not all words, sentences or sentences in physical books are indexed, and there are many physical books without an index from the beginning. Therefore, searching for a place such as a desired word or sentence from a physical book is less time-consuming and takes more time than searching while looking at pages sequentially.

  In addition, there is a widespread act of pinching stickers, sticky notes, etc. on the pages that attracted interest, but the stickiness of the parts hidden in the hooks decreased by sticking the stickers, etc. In some cases, it is difficult to distinguish between them, and it is cumbersome to work. In addition, although marking for drawing a line or the like at a corresponding portion is widely performed, there is a problem that the surface of a physical book is dirty and often becomes difficult to read due to the marking.

  In addition, when you want to convert a part of the contents of a physical book into electronic data, there are methods such as manual input or reading with an image scanner etc. to recognize the character. May not be performed accurately. In any case, it cannot be directly captured as electronic data.

  On the other hand, in the case of a virtual book or the like converted to electronic data (hereinafter referred to as “electronic book”) distributed on an electronic data storage medium represented by a CD-ROM or provided via a communication network, Attempts have been made to solve the above-mentioned problems by using the search function and heel function provided in the reading software. However, in the case of a CD-ROM or the like, it needs to be purchased separately, and a dedicated device may be required for reading the CD-ROM. When provided via a network, a connection environment to a communication network is required, and portability as in a physical book cannot be obtained. Many of these media are easy to copy, but for copyright protection, there are restrictions that can only be read by a dedicated device or a downloaded computer, or they have been crafted in a format that cannot be extracted as text data. Because it is provided, it is not easy to even quote as permitted by copyright. The system of Patent Document 1 also only provides electronic information related to a book, and cannot provide a desired portion of the text as electronic data.

Further, since the terminal may be a general-purpose computer, a dedicated device for reading and displaying the electronic data of the physical book is not necessary.

Embodiments of a physical book electronic data providing system according to the present invention will be described below with reference to the drawings.
FIG. 1 shows an identification code (hereinafter referred to as “book identification code”) uniquely assigned so that each physical book can be uniquely identified as an acquirer of the physical book (that is, a user of this system, hereinafter “ It is a figure which shows typically the flow given to a user. FIG. 1 shows an example in which the format identification code 20 is distributed to the users 30 when the physical book 10 is purchased. The user 30 purchases the physical book 10 at the bookstore and pays the price. At that time, a book identification code 20 is given. In addition to the example shown in FIG. 1, it is possible to notify the user by a method of notifying later at a dedicated application procedure.

  In any method, it is sufficient that the book identification code 20 can be notified only to the user 30 who is a valid purchaser of the physical book 10. Further, the book identification code 20 may be a character, number, symbol, or a combination of these that can be recognized by a person, but is not limited to this, and is a one-dimensional or two-dimensional barcode that cannot be recognized by a person. It may be read and input by a dedicated device or software.

  FIG. 2 is a diagram schematically showing both the left and right pages when the physical book 10 is opened. Each page of the physical book 10 is a page identification digitized code such as a bar code indicating a page number or vertical and horizontal location so that the page position (ie, page number) in the physical book 10 can be electronically identified. 11 is printed.

  Furthermore, in-page coordinate identification information 12 indicating coordinates represented by Anoto coordinates (see Patent Document 2) may be printed on each page of the physical book 10. Using this, position information (in-page coordinates) within each page can be input.

  FIG. 3 is a block diagram showing the entire service provided by the present system via the communication network. The terminal 100 can exchange data with the server 300 via the communication network 200. The communication network 200 is, for example, the Internet. The terminal 100 includes means for connecting to the communication network 200 (communication device and communication control software). For example, a modem, a router and a browser. In addition, an information input means 101 such as an input pen and a keyboard for reading and decoding the page identification computerized code 11 and the in-page coordinate identification information 12 attached to the physical book 10 shown in FIG. 2 and related software are introduced. Has been. Furthermore, an information output means 102 such as a display device for monitoring interactive data exchange with the server 300 is provided.

  The server 300 has various functions for providing services by this system. For example, the main functions include a page changing function 301, a bag function 302, a marker function 303, and a quoting function 304. Each of these functions is realized by an appropriate program. The processing flow executed by each function will be described later. Further, the server 300 includes several databases necessary for the present system. The book information database 310 stores electronic data of the contents of the physical book in association with the book identification code of each physical book, one of which is image data 311 of the text that is the printed contents. One is body text data 312. Further, both the image data 311 and the text data 312 are stored so that electronic data can be acquired for each page position of the physical book. That is, the electronic data of each page is associated with the page position in the physical book, that is, the page number.

  The book identification code-specific information database 320 is composed of several tables storing various data items for each book identification code. As main ones, there are a final display page table 321, a page table 322, a marking position / color table 323, an accumulated quote amount table 324, a latest quote time table 325, and a quote count table 326. The book information database 310 and the book identification code-specific information database 320 are controlled in association with each other when the above functions are executed. Details will be described later.

  The user uses this system to perform electronic reference including retrieval and citation regarding the acquired physical book. At that time, the user first tries to connect to the server 300 via the communication network 200 using the terminal 100. The server 300 has a Web server function, for example, and constructs a Web site that provides a service by this system, and the terminal 100 accesses the URL of this Web site using a browser. Upon receiving a connection start request from the terminal 100, the server 300 transmits a message that prompts the terminal 100 to input a book identification code.

  The terminal 100 receives this message and displays it on the information output means 102 such as a display device. When the book identification code is a character or a number, the user uses the information input means 101 such as a keyboard to key-in the book identification code. When the book identification code is an encoded code such as a barcode, the book identification code is input using the information input means 101 which is a dedicated reading device. The terminal 100 responds by transmitting the input book identification code to the server 300.

  When the server 300 receives the book identification code, the server 300 checks the book identification code and rejects the connection if it is illegal or is currently connected with respect to the book identification code. The server 300 registers each physical book to be processed and its book identification code in advance in the book information database 310 in association with each other.

In the following description of FIGS. 4 to 12, the reference numerals in FIG. 3 are used as appropriate.
FIG. 4 shows an inspection processing flow of the book identification code. In step 401, whether or not the book identification code is correct is checked with reference to the database. If the book identification code is registered in the book information database 310, it is determined that the book identification code is correct, and the process proceeds to step 402. If it is determined to be illegal, the connection is refused in step 404.

  Next, in step 402, the server 300 checks whether or not another user is connected based on the book identification code. This can be done, for example, by referring to whether the flag indicating whether or not the connection is in progress is on or off. If it is determined in step 402 that the connection is being established, the connection is rejected in step 404 because it is a double connection and there is a possibility of unauthorized use. If it is determined in step 402 that it is unused, connection is permitted in step 403, and a flag indicating that the book identification code is being connected is turned on (when access is completed, the flag is turned off). ). At the same time, a service screen is transmitted to the terminal 100 and displayed on the information output means 102. On the service screen, menu buttons and the like for selecting various functions provided by the server 300 are provided.

  On the service screen, for example, an area for displaying the page data of the designated book is provided. In addition, when the user requests one of the functions 301 to 304 of the server 300 shown in FIG. A menu display for selecting a function, a display field for input data from the keyboard, and the like are provided as appropriate.

  The server 300 accesses the electronic data that is the content of the corresponding physical book by referring to the book information database 310 using the book identification code as a key. When the page identification code transmitted from the terminal 100 is received, the corresponding page data (image data or text data depending on the function) is acquired using the page identification code as a key, transmitted to the terminal 100, and sent to the information display means 102. Display.

  For example, the image data 311 may be transmitted to the terminal 100 and displayed in the normal use mode in which there is no text data request (for example, use of the citation function or the marking function) from the terminal 100 at the beginning of connection. The image data 311 has a format in which a character string cannot be extracted by referring to a range, and the user only sees and reads what is displayed.

  The server 300 searches the book identification code-specific information database 320 using the book identification code as a key, and the final display page table 321, the page table table 322, and the marking position / color table 323 include data other than the initial values. For example, the situation at the previous use may be reproduced based on them. For example, the page data is transmitted and displayed based on the latest data stored in the final display page table 321. Further, for example, the corresponding page data is transmitted and displayed based on the page position of the valid page page stored in the page table 322. Further, for example, the page data is transmitted and displayed in a state where marking is performed using corresponding position information and color information based on valid marking information stored in the marking position / color table 323.

  FIG. 5 is a diagram schematically showing the usage status of the user in the normal usage mode. In one embodiment, the user first designates a desired page number on the service screen (for example, a numerical value is input from a keyboard to a predetermined input unit on the screen). Alternatively, when the physical page 10 is provided with an encoded page identification electronic code 11 such as a bar code as shown in FIG. 2, the page identification electronic of the desired page using the reader 101 as shown in FIG. The code 11 is read and the page position is indicated on the service screen 102.

  Alternatively, in the case of a physical book in which the coordinate position is printed with a barcode, the page identification computerized code is acquired by reading the barcode with the input device, thereby indicating the desired page position. Alternatively, in the case of a book using a medium on which ANOTO coordinates represented by ANOTO paper are printed, a page identification computerized code is acquired by reading the coordinates with an input device, thereby indicating a desired page position. Data of these page identification computerized codes is transmitted to the server. When the server receives the page identification computerized code, the server acquires the corresponding page data from the book information database 310, transmits it to the terminal, and displays the page data 103. This is a normal jump function.

  The page changing function 301 in FIG. 3 is processed as follows, for example. When the user instructs page turning on the service screen (eg, by clicking a predetermined menu button on the service screen), a page turning request is transmitted to the server. When the server receives the page turning request, the server acquires page data at the page position next to the currently displayed page from the book information database 310, and transmits it to the terminal for display. As a result, page turning is performed.

  In another example of the jump function, a jump by selecting a corresponding page from an index page or a table of contents page displayed on the screen is instructed (for example, a position of the corresponding page on the displayed index page or table of contents page is clicked). As a result, a jump request including the designated page position is transmitted to the server. When the server receives the jump request, it acquires the specified page data from the book information database 310, and transmits it to the terminal for display. Thereby, page switching is performed.

  In another example of the jump function, the index identification code of the physical book index page and table of contents page is read, and the headline and the in-page coordinate identification information of each item printed on the index page and table of contents page are read. When a jump request is made to the server, the server discriminates that the page is an index page or a table of contents page from the page identification computerized code and discriminates the designated page position from the in-page coordinate identification information. The page data is acquired from the book information database 310, transmitted to the terminal, and displayed. Thereby, page switching is performed.

  3 is processed as follows, for example. When a given page data is displayed on the service screen of the terminal 100, when the user gives an instruction to paste a candy on the page (for example, by clicking a predetermined menu button on the service screen), the candy is attached A request is sent to the server. The server 300 stores, in the book page code table 322 of the book identification code-specific information table 320, the number of the page (currently displayed page) to which the book is attached in association with the book identification code. FIG. 6 is a diagram illustrating an example of the page page table 322.

Thereafter, on the service screen, when the user instructs selection of the page (for example, by clicking a predetermined menu button), a page call request is transmitted from the terminal 100 to the server. When the server receives the page call request, the server refers to the page page table 322 using the book identification code as a key, acquires the stored page number, acquires the page data from the book information database 310, and sends it to the terminal 100. Send and display. When a plurality of page numbers are acquired, they are transmitted to the terminal 100 for display, and the user further selects any page and transmits the page data to the terminal 100 in response to the selection. Display. A configuration is also possible in which each of a plurality of wrinkles can be identified by giving a comment to the wrinkles when a wrinkle sticking request is made.
Note that the server 300 can delete the data stored in the page table 322 in response to a request from the terminal 100.

  FIG. 7 shows the usage status of the search function of the server. The user inputs a search condition (for example, the word “Horyuji”) in the input data display field 104 on the screen using the information input means 101 such as a keyboard on the service screen 102 on the terminal 100, and clicks the menu button 105. Search instructions. Thereby, a search request including search condition data is transmitted to the server. The server 300 that has received the search request searches the text data 312 in the book information database 310 of FIG. 3, and if there is a page that satisfies the search condition, transmits the page data to the terminal 100, and uses the information output means 102. The page 106 is displayed. As a result, the user can know which page of the physical book he / she has and the text corresponding to the search condition.

  FIG. 8 shows the usage status of the marker function 303 of the server 300 shown in FIG. When using the marker function, the text data 312 is acquired from the book information database 310 of FIG. 3 instead of the screen data 311 and displayed on the service screen 102. The text data 312 has a format in which a character string can be extracted by referring to a range. The transition from the screen data to the text data is performed by requesting the server 300 (for example, selecting a marker function with a menu button). In the service screen 102 on the terminal 100, a portion 107 to be marked on the page displayed on the screen is designated by a rectangular area designation, page designation, line designation, multipoint area designation or the like using an information input means 101 such as a keyboard or a mouse. Specify the marking area by specifying the graphic area. Thereafter, the menu button 108 on the service screen is clicked. Thereby, a marking request including the marking area designation data is transmitted to the server. The server 300 that has received the marking request realizes marking on the service screen 102 by displaying the designated marking area separately from other areas (for example, character enclosure or color characters). At the same time, as illustrated in FIG. 8, marking information is stored in the marking position / color table 323 of the book identification code-specific information table 320 of the server 300 in association with the book identification code. The marking information includes the page number where the marking area exists, the coordinates within the page, and the marking method (character enclosure shape, color, etc.).

  Thereafter, the terminal 100 requests the server 300 to call existing marking information (for example, clicks a menu button on the service screen). In response to the marking information call request, the server 300 refers to the marking position / color table 323 using the book identification code as a key, and transmits the page data to the terminal 100 based on the page number included in the acquired marking information. Let When displaying, the area is displayed in a marked state in accordance with the stored in-page coordinates and marking method. Note that this jumps to the page on the service screen of the terminal 100.

The designation of the marking area in the marker function 303 may be performed by reading the in-page coordinate identification information attached to the physical book, in addition to instructing on the service screen of the terminal 100 as described above. For example, in the case of a physical book in which the coordinate position is printed with a barcode, the coordinates are designated by reading the barcode with the input device. In another example, in the case of a physical book using a medium printed with coordinates represented by Anoto Paper, the coordinates can be specified by reading the coordinates with an input device.
The server 300 can delete the data stored in the marking position / color table 323 in response to a request from the terminal 100.

  FIG. 9 is a block diagram showing the processing status of the citation function 304 of the server 300 shown in FIG. When the citation function is used, the text data 312 is acquired from the book information database 310 of FIG. 3 instead of the screen data 311 and displayed on the service screen 102. The text data 312 has a format in which a character string can be extracted by referring to a range. The transition from the screen data to the text data is performed by requesting the server 300 (for example, selecting a marker function with a menu button). In the service screen 102 of the terminal 100, the user designates a reference area of a portion 110 to be quoted on the page displayed on the screen by rectangular area designation, page designation, line designation, multipoint area designation, or graphic area designation, Click the menu button 110. Thereby, a citation request including the citation area designation data is transmitted to the server 300. The server 300 that has received the citation request acquires the text data 312 corresponding to the citation area designated by referring to the book information database 310 using the book identification code as a key, and converts the text data of that portion into a downloadable format. (A part of the processing of the quoting function 304) and store it as a citation information file 330. The citation information file 330 can be downloaded in response to a request from the terminal 100.

  The designation of the citation area in the citation function 304 may be performed by reading the in-page coordinate identification information attached to the physical book, in addition to instructing on the service screen of the terminal 100 as described above. For example, in the case of a physical book in which the coordinate position is printed with a barcode, the coordinates are designated by reading the barcode with the input device. In another example, in the case of a physical book using a medium printed with coordinates represented by Anoto Paper, the coordinates can be specified by reading the coordinates with an input device.

In the citation function 304, each process shown in the flow of FIGS. 10 to 12 may be performed, or one or more of these processes may be performed in combination.
FIG. 10 shows a processing flow using the cumulative citation amount table 324 of the book identification code-specific information database 320 of FIG. The accumulated citation amount table 324 stores past accumulated citation data amounts in association with book identification codes. Upon receiving the citation request, the server 300 refers to the accumulated citation amount table 324 using the book identification code as a key, adds the current citation data amount to the past citation data amount, and calculates the total citation data amount in step 1001. To do. In step 1002, it is determined whether or not the total citation data amount has exceeded a preset assumed citation data amount. If not, the citation request is permitted in step 1003, and the process described with reference to FIG. 9 is executed. If so, the citation request is rejected in step 1004. As a result, the upper limit of the cited data amount is appropriately maintained. Note that the cumulative citation amount table 324 is updated so that the total citation data amount calculated in step 1001 becomes a new past cumulative citation data amount.

  FIG. 11 shows a processing flow using the latest citation time table 325 of the book identification code-specific information database 320 of FIG. The latest quote time table 325 stores the latest quote time in association with the book identification code. When receiving the citation request, the server 300 calculates an elapsed time between the current date and time and the latest citation time in step 1101. In step 1102, it is determined whether or not the elapsed time exceeds a preset expected time. If exceeded, the quotation request is permitted in step 1103, and the process described with reference to FIG. 9 is executed. If not, step 1204 rejects the citation request. As a result, the use interval of the citation function is appropriately maintained. The latest quote time table 325 is updated so that the current date and time is the new latest quote time.

  FIG. 12 shows a processing flow using the citation count table 325 of the book identification code-specific information database 320 of FIG. The citation count table 325 stores past citation counts in association with book identification codes. Upon receiving the citation request, the server 300 refers to the accumulated citation count table 324 using the book identification code as a key in step 1201, adds 1 to the past citation count, and calculates a new citation count. In step 1202, it is determined whether or not the number of citations exceeds a preset number of citations. If not, the citation request is permitted in step 1203, and the process described with reference to FIG. 9 is executed. If so, the quote request is rejected at step 1204.
