Description

TECHNICAL FIELD

[0001] The present invention relates to electronic book publishing systems and publishing methods and to electronic information distributing apparatuses.

BACKGROUND ART

[0002] In general, travelers carry a guidebook. Such a guidebook contains articles on travel preparation, airline ticket reservation, hotels, and the like. Travelers frequently use the guidebook by referring to pages with articles relevant to the trip. Some guidebooks include maps, practical articles on the local language, and the like. As time passes, these articles differ from the actual conditions. Revised editions are published relatively frequently for the convenience of readers. However, as for conventional published books, more detailed and specific contents would require the bookbinding to be thicker

[0003] Instead of books formed of printed paper, electronic books formed of electronized data have come to be widely used in many fields in order to reduce size and weight. One type of such an electronic book is one wherein information is written in a built-in ROM and read out from the ROM to be displayed. Another type includes a recording medium, such as a CD-ROM or a memory card, which is installed and read. It is likely that more and more electronic books using a removable recording medium such as a CD-ROM will be widely used since new content can be read at any time and hardware can be used continuously.

[0004] The above-described related art has the following problems to be solved.

[0005] For example, when a traveler carries a guidebook during his/her journey, the traveler may write down his/her comments on his/her journey in the guidebook. When the traveler finds an error in an article or obtains the latest information, the traveler may write it down in the guidebook in order to make the best use of it for a subsequent journey. Such information is not only useful to the carrier of the guidebook but also to other readers. Utilization of such information can improve the quality of the guidebook.

[0006] However, if information is collected from readers, it takes some time before the next revised edition can be printed. Handling of the collected information is not easy and depends on the editor's ability. In fact, there are many cases in which useful information is not utilized. Electronic books are often issued after books are printed. It is well desired to provide a system for extensively collecting new information and reflecting the information in publication.

[0007] Travel guidebooks are revised relatively frequently in order to reflect changes in public transportation schedules, hotel lodging expenses, and the like. However, it takes time to edit and print books. Even when a traveler purchases the latest edition and goes on a journey, the information on the guidebook may often be different from the actual situations. Information on relatively unpopular places is often old. Electronic books which use electronic data as a medium have a better chance of appropriately dealing with these changes in information immediately than books which use paper as a medium. For example, with a system capable of downloading the latest information through the Internet or the like, a travel guidebook which always contains the latest information can be realized.

[0008] When information of a size comparable to that of information included in the actual guidebook on sale is electronized, the amount of data becomes extremely large. There is a problem in that it takes a long period of time to download the information via a network. In a system for selling CD-ROMs at a book store, downloading is unnecessary. However, as with publishing books, there is a problem in that issuing CD-ROMs is slow to deal with changes in information.

[0009] As in newspapers and magazines, there is a system for speeding up the cycle from collecting information to publication, and for frequently publishing revised editions. When a traveler carries a guidebook on his/her journey, the traveler may write down his/her comments on his/her journey. When the traveler finds an error in an article or obtains the latest information, the traveler may write it down in the guidebook in order to make the best use of it for a subsequent journey. When revised editions are published frequently, such written information cannot be utilized unless it is posted. Since electronic books are read-only files, it has been impossible to write information into the electronic books.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0121] Embodiments of the present invention will now be described with specific examples.

[0122] (First Embodiment)

[0123] (System Configuration)

[0124] FIG. 1 is a conceptual diagram showing a specific example of an electronic book publishing system of the present invention.

[0125] The illustration shows the flow of electronic book data and information provided by a user in the electronic book publishing system. A user terminal 4 and a host computer 5 are connected to a network 3 such as the Internet. The user displays and utilizes electronic book data 26 stored in a container 1 such as a floppy disk using an electronic book 20. In the drawing, the electronic book 20 and the user terminal 4 are connected to each other by an interface cable 28 so that provided information 27 stored in the container 1 can be transmitted to the host computer 5.

[0126] The user stores comments made while looking at the electronic book data 26 for, for example, a travel guidebook and errors detected in the electronic book data 26 as the provided information 27 in the container 1. The user transmits the provided information 27 to the host computer 5 so that these pieces of information can be reflected in electronic book data to be subsequently published. In this system, the user participates in publishing electronic book data. As described hereinafter, the user can store various types of information other than the information provided in the container 1. In the drawing, only the provided information 27 is shown.

[0127] A publisher 6, shown in the drawing, publishes various electronic books and sells these electronic book data at a store 8. The electronic book data is stored in the container 1 such as a floppy disk and is sold. The store 8 at which the electronic book data is sold may be a book store or a convenience store. The provided information 27 from the user is collected by information collecting means 9 of the host computer 5, and is stored in a storage unit 10.

[0128] Editing means 11 edits the collected provided information 27 and adds the edited provided information 27 to electronic book data published by the publisher 6. For example, the editing means 11 extracts pieces of information designated by an operator (not shown) out of the provided information 27 from the storage unit 10 and edits an electronic book page in which the pieces of provided information are arranged as in a letter-to-the editor column. Provided information other than the designated pieces can be thrown out. Distribution means 15 is a portion which performs processing to distribute the electronic book data to which the edited provided information is added. For example, the distribution means 15 makes a large number of copies of the container storing the provided information and the electronic book data. The copied containers are dispatched to the store 8.

[0129] The container 1 storing the electronic book data 26 may be a recording medium, such as a memory card or a floppy disk, or a built-in memory in the electronic book 20. In other words, the container 1 is not necessarily required to be removable from the electronic book 20. The host computer 5 collects the provided information 27 through an arbitrary interface. In the example shown in the drawing, the user terminal 4 and the network 3 are used as an interface. Alternatively, for example, a terminal for collecting provided information can be installed at the store 8 so that the user can freely use the terminal.

[0130] Preferably, the terminal (not shown) installed at the store 8 not only collects the provided information but also has a function of updating electronic book data used by the user. The terminal simultaneously updates the electronic book data and collects the provided information. Also, the terminal can distribute the provided information. Accordingly, collecting the provided information from the user and feeding the provided information back to the user can be performed simultaneously. The provided information can be added to the electronic book data and distributed. Alternatively, the provided information can be distributed independently of the electronic book data. When the electronic book 20 has a cellular phone function, a cellular phone network is used as the network 3, and updating and collection and distribution of information can be performed. At this time, the user terminal 4 is a cellular phone or a mobile computer.

[0131] The system shown in the drawing is provided with fee computing means 12. The collected provided information 27 is, for example, edited and evaluated by an editor (not shown), and the quality of the provided information 27 is judged. At the same time, the rank of a fee to be paid to the provider of the information is determined. The fee computing means 12 automatically issues a message for the purpose of paying a fee and makes a remittance. With the system, useful information can be collected more easily. Optionally, the system can register the provider of the information as a member and automatically reimburse the user by canceling out the charge for updating the electronic book data as for the information provided.

[0132] (Structure of Electronic Book)

[0133] The structure of an electronic book which is effective in operating the system as described above will now be described.

[0134] FIG. 2(a) is a plan view of an electronic book for implementing the present invention, and FIG. 2(b) is a perspective view thereof.

[0135] An electronic book 20 can be folded in half at a portion indicated by arrow A in FIG. 2(a). The state in which the electronic book 20 is folded is shown by FIG. 2(b). The electronic book 20 includes a display 21 which displays a screen 23 of a travel guidebook. As shown in FIG. 2(b), the container 1 is mounted on a lateral side of the electronic book 20. In this example, the container 1 is a floppy disk, and the electronic book 20 includes a floppy disk drive 24. The container 1 is placed in the floppy disk drive 2A. In addition to this, the electronic book 20 is provided with an electronic camera 25. An image captured by the electronic camera 25 is stored in the container 1. The image data can also be used as provided information.

[0136] FIG. 3 illustrates the contents of electronic information to be stored in the container.

[0137] When the electronic information is for a travel guidebook, for example, the entire data is divided into blocks according to destination. In this drawing, a large block 30 “Travel Guide to India” is shown. The large block 30 includes data for subdivided blocks including public transportation, restaurant guide, hotel guide, and the like. For example, the electronic book data can be updated in units of large blocks or in units of subdivided blocks. Accordingly, the cost of obtaining the latest electronic book data can be reduced. If the amount of data is reduced, the cost and time for updating data through a communication network can be saved.

[0138] For example, a block 31 shown in FIG. 3 includes main data 32, version data 33, and link data 34. The main data 32 includes text data and image data for displaying articles on public transportation used for traveling in India. The version data 33 includes data indicating the version of the block and is used to determine whether it is necessary to update the data or not. In the example shown in the drawing, the version data 33 is included in management data 13 separately from the main data 32. Version data 38 in the large block 30 is similarly included in the management data. The management data 13 is stored in the container 1.

[0139] The link data 34 includes data for linking the main data 32 with data additionally written by the user in association with the articles in the main data 32 in the block. For example, the link data 34 includes data describing an icon arranged in the displayed electronic book data and a command for opening a data file which is additionally written by the user in response to clicking the icon. Examples of data written by the user include written data 35, memo data 36, image data 37, and the like.

[0140] The written data 35 includes data generated by the user who writes down comments regarding arbitrary articles while looking at the display (FIG. 2) of the electronic book. The written comments are saved as the written data 35. The memo data 36 includes data generated by the user who saves his/her comments regarding the corresponding block as a file in a text data format. The image data 37 includes a hand-drawn image, an image received from a scanner, and an image captured by the electronic camera 25 (FIG. 2). In this example, the written data 35, the memo data 36, and the image data 37 are all stored in the container 1. When a block is updated, only the main data 32 is rewritten.

The updating block determination unit 104 has functions to read the electronic information 111 stored in the container 101 through the interface 108, detect the version of each block 112 of the electronic information 111, and determine whether or not to update the electronic information 111 in block units. Thus, the electronic information 111 includes table data for displaying a list of versions of all the blocks. This is included in management data 113.

[0160] The display unit 107 is used to display the determination results of the updating block determination unit 104. Based on the determination results of the updating block determination unit 104, a user can detect blocks whose versions are old. The display unit 107 displays block designation means 115. The block designation means 115 includes a list of blocks to be updated and a window displaying a group of check boxes for designating blocks that the user wants to update. The updating processor 105 has functions to transmit, when the user operates the block designation means 115 and designates a block(s) to be updated, the corresponding block(s) to the container 101 through the interface 108 and update the corresponding blocks.

[0161] The updating fee computing unit 106 has a function to compute the updating fee to be charged to the user on the basis of the updating result. The number of updated blocks, and the like are taken into consideration in computing the updating fee. The result of computing the updating fee is, for example, printed by the printer 109. The printer 109 is used to issue a bill. The bill is used in such a manner that the user brings the bill to a cashier (not shown) and pays the updating fee.

[0162] The updating block determination unit 104, the updating processor 105, and the updating fee computing unit 106 are implemented by a computer program executed by a processor (not shown) of the electronic information distributing apparatus 110.

[0163] FIG. 8(a) is a plan view of an electronic book for implementing the present invention, and FIG. 8(b) is a perspective view thereof.

[0164] An electronic book 120 can be folded in half at a portion indicated by arrow A in FIG. 8(a). The state in which the electronic book 120 is folded is shown by FIG. 8(b). The electronic book 120 includes a display 121 which displays a screen 123 of a travel guidebook, for example. As shown in FIG. 8(b), a container 101 is mounted on a lateral side of the electronic book 120. In this example, the container 101 is a floppy disk, and the electronic book 120 includes a floppy disk drive 124. The container 101 is placed in the floppy disk drive 124. In addition to this, the electronic book 120 is provided with an electronic camera 125. An image captured by the electronic camera 125 is stored in the container 101.

[0165] FIG. 9 illustrates the contents of electronic information to be stored in the container.

[0166] When the electronic information is for a travel guidebook, for example, the entire data is divided into blocks according to destination. In this drawing, a large block 130 “Travel Guide to India” is shown. The large block 130 includes data for subdivided blocks including public transportation, restaurant guide, hotel guide, and the like. For example, the electronic book data can be updated in units of large blocks or in units of subdivided blocks.

[0167] For example, a block 131 shown in FIG. 9 includes main data 132, version data 133, and link data 134. The main data 132 includes text data and image data for displaying articles on public transportation used for traveling in India. The version data 133 includes data indicating the version of the block and is used to determine whether it is necessary to update the data or not. In the example shown in the drawing, the version data 133 is included in management data 113 separately from the main data 132. Version data 138 in the large block 130 is similarly included in the management data. The management data 113 is stored in the container 101. Accordingly, the updating block determination unit 104 shown in FIG. 7 can determine the version of each block.

[0168] The link data 134 includes data for linking the main data 132 with data additionally written by the user in association with the articles in the main data 132 in the block. For example, the link data 134 includes data for associating the identification number of a block with a storage location of data additionally written by the user. This is provided in order to manage data added to each block. Examples of data additionally written by the user include the written data 135, the memo data 136, the image data 137, and the like.

[0169] The written data 135 includes data generated by the user who writes down comments regarding arbitrary articles while looking at the display (FIG. 8) of the electronic book. The written comments are saved as the written data 135. The memo data 136 includes data generated by the user who saves his/her comments regarding the corresponding block as a file in a text data format. The image data 137 includes a hand-drawn image, an image received from a scanner, and an image captured by the electronic camera 125 (FIG. 8). In this example, the written data 135, the memo data 136, and the image data 137 are all stored in the container 101. When a block is updated, only the main data 132 is rewritten. The link data 134, the written data 135, the memo data 136, and the image data 137 are succeeded without being changed. To this end, the main data 132 is stored separately from the other data. The link data 134, the written data 135, the memo data 136, and the image data 137 are referred to as succession information 140.

[0170] Accordingly, even when information is written in a certain block in the travel guidebook, and the block is updated, the written information is stored unaltered. The information including the succession information can be used even when the container 101 is mounted on a different electronic book as long as all the information concerning the travel guidebook is stored in the container 101.

[0171] FIG. 10 is a flowchart showing the updating operation of the electronic information distributing apparatus shown in FIG. 7.

[0172] With the flowchart, the operation of the electronic information distributing apparatus 110 when the user of the electronic book 120 updates the travel guidebook stored in the container 101 will now be described. The user removes the container 101 from the electronic book 120. The user mounts the container 101 on the interface 108 of the electronic information distributing apparatus 110 shown in FIG. 7 and presses an update start button (not shown) displayed on the display unit 107. The display unit 107 is a touch panel. The display unit 107 can be operated by pressing a displayed image. The latest-version electronic information 111 is downloaded from a host computer (not shown) and stored in the storage unit 103 of the electronic information distributing apparatus 110.

[0173] When the updating operation starts, in step S1, the interface 108 reads data from the container 101 and transfers the data to the updating block determination unit 104.

[0174] The updating block determination unit 104 refers to the management data 113 stored in the container 101, and compares the data with the latest-version electronic information stored in the storage unit 103 and searches for blocks which are not the latest version (step S2). As a result, blocks to be updated are displayed on the display unit 7 (step 3).

[0175] On the display unit 107, the block designation means 115 shown in FIG. 7 is provided with contents 115A of the blocks to be updated and check boxes 115B to be checked when the user wants to update the corresponding blocks. When the check box 115B is pressed by finger, the check box 115B is checked, and hence the block to be updated can be designated. Subsequently, when an update start button 115C is pressed, the updating processor 105 detects blocks which are designated to be updated by the block designation means 115 (step S4).

[0176] The updating processor 105 reads data for the corresponding blocks from the storage unit 103, transfers the data to the container 101, and updates the blocks (step S5). The processing is performed only for the main data 132 (FIG. 9) of each block 112 which has already been described. The updating fee computing unit 106 accumulates updating charges for updated blocks and computes an updating fee. Based on the result, the printer 109 prints a bill (step S7). The interface 108 ejects the updated container 1 and returns the container 1 to the user (step S8). The user pays the fee on the bill at a cashier, mounts the container 1 on the electronic book 120, and starts using the updated-version travel guidebook.

[0177] When electronic book data is updated in units of blocks designated by the user by the above-described method, only necessary portions of the electronic book data are quickly updated at low cost. In the guidebook, only information which tends to change due to the local circumstances, namely, ticket prices, dining expenses, accommodation expenses, and medical expenses, can be updated immediately before traveling, enabling the user to use the latest information during his/her travel. As described above, updating can be performed in units of large blocks or in units of subdivided blocks. Thus, updating fees differ according to the blocks to be updated. When the block designation means 115 display updating fees in units of blocks to be updated, the user can select blocks to be updated in accordance with his/her budget.

[0178] FIG. 11 is a block diagram of an updating system using a network including the electronic information distributing apparatus, the electronic book publisher, and the user.

[0179] As shown in the drawing, a user terminal 151, a host computer 152 of the electronic book publisher, and the electronic information distributing apparatus 110 are connected to a network 150 such as the Internet. When the publisher publishes an electronic book, the publisher sells a container 155 containing the entire electronic book. For example, containers for electronic books in various fields are on a shelf 154 of a convenience store 160 and are on sale. A user who purchases the container 155 uses the container 155 on his/her electronic book 120.

[0180] In the convenience store 160, the above-described electronic information distributing apparatus 110 is installed. The user brings the container 101 to the convenience store 160 and updates the container 101. In this system, the container 101 can be updated by using the user terminal 151. In this case, electronic book data is downloaded in block units through the network 150. Preferably, updating can be performed by connecting the electronic book 120 and the terminal 151 to each other through an interface cable 153. In this case, the electronic book 120 becomes the display unit 107 shown in FIG. 7, and the block designation means is displayed on the electronic book. In this case, the updating fee may be paid by card or the like. The network 150 shown in the drawing may be a wireless network for cellular phones and the like. In this case, the terminal 151 may be a cellular phone or a mobile computer.

[0181] The above described cases are illustrative examples, and the present invention is not limited thereto. Functional blocks in the electronic information distributing apparatus 110 shown in FIG. 7 may be formed of separate program modules or formed of an integrated program module. All or some of the functional blocks may be formed of logical circuit hardware. Each program module may be loaded into a known application program and operated or may be operated as an independent program. The functions of the electronic information distributing apparatus 110 can be implemented by installing a computer program which operates as described above on a known computer. The computer program for implementing the present invention may be recorded on a computer-readable recording medium such as a CD-ROM, and the computer program may be installed and used. The computer program may be downloaded via a network into a memory of a computer and be used.

[0182] As described above, electronic books are small and lightweight and are easy to carry. Creation of an environment for updating electronic information on an electronic book in block units at a convenience store enables a user to use an electronic book which always contains the latest information when necessary. With a system for comparing the current contents with the latest contents and only updating portions designated by the user, updating can be performed in a short period of time. This lessens the burden on the user and reduces the cost of providing information. Furthermore, data including written data can be updated. It is thus possible to achieve an electronic information distributing apparatus which uses the electronic book including user's original information.
