Description

  The present invention relates to an electronic book display method, an electronic book display device, and an electronic book display program.

  In recent years, electronic books distributed via a communication line such as the Internet or provided via a storage medium such as a memory card have been widely used. A user usually displays an electronic book on a terminal having a display function such as a smartphone or a tablet terminal for browsing.

  Conventionally, in order to provide a user who resumes reading of digitized book data to provide commentary data that explains the content up to the part where reading was interrupted, one of a plurality of commentary data prepared in advance is provided. A technique for selecting and presenting explanatory data is known (see, for example, Patent Document 1).

  In addition, when resuming reading of an electronic book, a technology is known that performs a review display that displays from a location that goes back a predetermined range from the interruption location and automatically advances from the retroactive location to the interruption location. (See, for example, Patent Document 2)

JP 2001-222540 A JP 2010-9461 A

  However, in Patent Document 1, it is necessary to prepare a plurality of comment data in advance, but it is difficult to prepare comment data for a large number of electronic books in advance. Further, in the above-mentioned Patent Document 2, the screen is displayed retrospectively by a predetermined number of retroactive pages from the interrupted point. However, since the retroactive page number is set for each ratio of the book genre and the number of characters, reading is interrupted for a long time. In such a case, the user may not be able to display the screen retrospectively to a location desired by the user.

  In one aspect, an object of the present invention is to provide an electronic book display method, an electronic book display device, and an electronic book display program capable of easily remembering the contents up to the interrupted page when browsing of the electronic book is resumed. .

  In one aspect, the electronic book display method stores the page displayed at the end of the accessed electronic book data and the access end time, and when the access to the electronic book data is accepted again, the previous access is performed. When the screen containing the electronic book data of the page that was last displayed and the first button for accepting the user's operation is displayed, and when the operation of the first button is accepted, the current access starts from the previous access end time This is an electronic book display method in which a computer executes a process of displaying a screen including electronic book data of pages returned by the number of pages according to the elapsed time up to the time.

  In one aspect, the storage unit that stores the last displayed page of the electronic book data that has been accessed and the access end time, and the storage unit that stores the access when the electronic book data is accessed again A first display control unit that displays a screen including the electronic book data of the page that was last displayed at the time of the previous access and a first button that accepts a user operation, and pressing the first button A second display control unit that displays a screen including electronic book data of a page returned by the number of pages corresponding to the elapsed time from the previous access end time to the current access start time.

  In one aspect, the page and the access end time displayed at the end of the accessed electronic book data are stored, and when the access to the electronic book data is accepted again, the last display is performed at the time of the previous access. When the screen including the electronic book data of the page and the first button for accepting the user's operation is displayed and the operation of the first button is accepted, the elapsed time from the previous access end time to the current access start time is displayed. This is a program for causing a computer to execute a process of displaying a screen including electronic book data of a page returned by a corresponding number of pages.

  It is possible to make it easier to remember the content up to the interrupted page when resuming browsing of an electronic book.

In the user terminal 70, the function shown in FIG. 3 is realized by the CPU 190 executing the program.

  FIG. 3 shows a functional block diagram of the server 10 and the user terminal 70. As shown in FIG. 3, in the server 10, the function as the management unit 12 is realized by the CPU 90 executing a program (including an electronic book display program). Further, in the user terminal 70, functions as the display processing unit 72 and the input processing unit 74 are realized by the CPU 190 executing the program. In FIG. 3, a user-specific return DB (database) 20 as a trend storage unit, a reading history DB 22 as a storage unit, a user DB 24, a book DB 26, and rental books stored in the HDD 96 of the server 10. DB 28 is also illustrated.

  The management unit 12 of the server 10 uses various databases to execute an electronic book lending process, an electronic book viewing screen transmission process for the user terminal 70, and the like. The display processing unit 72 of the user terminal 70 receives the electronic book browsing screen data transmitted from the management unit 12 and displays the browsing screen on the display unit 193. The input processing unit 74 receives a user operation (lending request operation, browsing screen page turning operation, page return operation, etc.) and transmits it to the management unit 12.

  Hereinafter, the database used by the management unit 12 will be described in detail.

  FIG. 4 shows an example of the data structure of the return DB 20 for each user. The return DB 20 for each user is a database that stores a tendency of how much a user returns (goes back) to a page when each user resumes reading an electronic book of each genre. Here, when resuming reading of an electronic book, the user may go back several pages and perform an operation to remember the contents. In this embodiment, the return tendency of each user when reading is resumed is managed using the return DB 20 for each user. As shown in FIG. 4, the return DB 20 for each user has fields of “user ID”, “genre”, “elapsed days”, “average return page”, “total return page”, and “total number of times”. . The user identification information is stored in the “user ID” field. In the “genre” field, the genre name (for example, novel, business, text, etc.) of the electronic book is stored. In the “Elapsed Days” field, information indicating how much time has passed since the day when reading of the electronic book was interrupted (“1 day to”, “3 days to”, “7 days to”, etc.) is stored. . The field of “average return page” stores information on how much each user first returns to the page when reading is resumed after the elapsed days. The “total return page” field stores the total number of pages returned when each user resumed reading in the past, and the “total count” field stores each user, each genre, and each elapsed day. Stores the number of reading restarts. The “average return page” field stores a value obtained by dividing “total return page” by “total number of times” (rounded off or rounded off after the decimal point).

  FIG. 5 shows an example of the data structure of the reading history DB 22. This reading history DB 22 manages history information such as when and what books have been read to what extent when the user has read. Specifically, the reading history DB 22 includes fields of “user ID”, “electronic book ID”, “genre”, “interruption date / time”, “interruption page”, and “maximum return number”. The “user ID” stores user identification information, the “electronic book ID” field stores electronic book identification information, and the “genre” field stores electronic book genre. Is done. In the “interruption date / time” field, information on the date / time when reading is interrupted is stored, and in the “interruption page” field, the number of the page displayed last when reading is interrupted is stored. In the “maximum return number” field, the maximum number of pages returned in reading is stored.

  FIG. 6A shows an example of the data structure of the user DB 24. The user DB 24 stores information on users registered in the library. Specifically, as shown in FIG. 6A, the user DB 24 has fields of “user ID”, “name”, and “generation”. The “user ID” field stores the identification number of the user, and the “name” field stores the name of the user. The “generation” field stores the generation of the user (10th generation, 20th generation,...).

  FIG. 6B shows an example of the data structure of the book DB 26. The book DB 26 stores information on books (including paper media) held in the library. As shown in FIG. 6B, the book DB 26 has fields of “book ID”, “book name”, “author”, “genre”, and “total number of pages”. In the “book ID” field, book identification information is stored. The “book name” field stores the name of the book, the “author” field stores the name of the author of the book, and the “genre” field stores the genre name of the book. Also, information on the total number of pages of the book is stored in the “total number of pages” field.

  FIG. 7 shows an example of the data structure of the lent book DB 28. The rental book DB 28 is a database that manages information related to the rental of electronic books to users. As shown in FIG. 7, the loan book DB 28 includes fields of “electronic book ID”, “borrower”, “loan date”, “return date”, and “arrears”. In the “electronic book ID” field, identification information of electronic book data is stored. The electronic book ID is obtained by adding a two-digit number to the end of the book ID (see FIG. 6B). The last two digits are different for each electronic book data. The “borrower” field stores the user ID of the user who borrows the electronic book. In the fields “lending date” and “return date”, the date when the electronic book is lent and the return date of the electronic book are stored. When the date in the “return date” field is a date earlier than the current date, the flag “■” is stored in the “Arrears” field. Note that when an electronic book of a record stored in the lent book DB 28 is returned, the record is deleted from the lent book DB 28.

  FIG. 8 shows a data structure of a worksheet used when the management unit 12 executes the process. The worksheet is used to acquire the tendency of the return page until the user reads a predetermined number (for example, 10) of electronic books of a certain genre. As shown in FIG. 8, the worksheet has a data structure in which a field of “total number of books” is added to the return DB 20 for each user shown in FIG. The “total number of books” field stores how many electronic books of each genre the user has read in the past. In addition, when a certain user reads a predetermined number (for example, 10) of electronic books of a certain genre, the management unit 12 transfers information on the genre of the user from the worksheet to the return DB 20 for each user. To do. Then, the genre information in the worksheet is deleted.

(Processing of the management unit 12)
Next, the process of the management unit 12 will be described in detail along the flowcharts of FIGS. 9 to 12 with reference to other drawings as appropriate. Note that the lending of an electronic book means that an access right to the data of the electronic book is granted to a user who has made a request for lending the electronic book. 9 to 12 are processes that are started when an electronic book browsing request is received from the user terminal 70 to the management unit 12. That is, the processes in FIGS. 9 to 12 are executed in response to a browsing request from a user who has already borrowed one or more electronic books.

  First, the management unit 12 performs user authentication (not shown) for a user (user ID) who has requested browsing of a lent book, and in step S10 of FIG. Based on the book DB 26, the book name, author, and genre borrowed by the user are acquired. In this case, the management unit 12 refers to the lent book DB 28 and acquires the electronic book ID of the record stored in the field where the user ID of the user is “borrower”. And the management part 12 acquires the book name, author, and genre corresponding to acquired electronic book ID with reference to book DB26.

  Next, in step S12, the management unit 12 generates book list screen data and transmits the screen data to the user terminal 70 (display processing unit 72). The display processing unit 72 displays a screen as shown in FIG. 13A on the display unit 193 of the user terminal 70 when the screen data is received.

  Next, in step S14, the management unit 12 waits until receiving an electronic book selection. In this case, when the user selects a book name on the screen of FIG. 13A, the input processing unit 74 transmits information on the selected book to the management unit 12, and therefore the management unit that has received the information. In step 12, the process proceeds to step S16.

  In step S16, the management unit 12 executes a subroutine for user-specific work control processing. In the subroutine of step S16, processing according to the flowchart of FIG. 10 is executed.

  In the process of FIG. 10, in step S100, the management unit 12 refers to the reading history DB 22 and determines whether there is a record of the same genre as the selected book. That is, it is determined whether the user has read electronic books of the same genre in the past. For example, if the user with user ID = 001 has selected an electronic book of the genre “text” in step S14, there is no record of the genre “text” in the reading history DB 22 of FIG. Judgment is denied. In this case, the process proceeds to step S102, and the management unit 12 creates a record of the genre of the electronic book selected by the user on the worksheet (FIG. 8), and sets the cumulative number of books to 1. Thereafter, the process proceeds to step S18 in FIG.

  On the other hand, for example, if the user ID = 001 has selected an electronic book of the genre “Novel” in Step S14, a record of the genre “Novel” exists in the reading history DB 22 of FIG. The determination in S100 is affirmed. In this case, the process proceeds to step S104, and the management unit 12 determines whether or not an electronic book of the same genre as the selected electronic book has been read (for example, 10). In this case, the management unit 12 refers to the worksheet and determines whether or not a predetermined number (for example, 10) is stored in the “total number of books” field of the genre. If the determination in step S104 is affirmative, that is, if the user has read a predetermined number (ten) of electronic books of the genre, the management unit 12 proceeds to step S106.

  If transfering it to step S106, the management part 12 will produce the record of the genre of the selected electronic book in return DB20 classified by user. That is, when a user reads a predetermined number (10) of electronic books of the same genre, a record of that genre is created in the return DB 20 for each user.

  Next, in step S108, the management unit 12 creates a return history (elapsed days, average return page, total return page, and total number of times) for the same genre as the electronic book selected on the worksheet, by the user-specific return DB 20 Migrate to

  Next, in step S110, the management unit 12 deletes a record of the same genre as the electronic book selected in the worksheet. Thereafter, the management unit 12 proceeds to Step S18 in FIG.

  On the other hand, if the determination in step S104 is negative, that is, if the number of books read from the electronic book of the same genre as the electronic book selected by the user is less than the predetermined number or more than the predetermined number, the management unit 12 The process proceeds to step S112.

  If transfering it to step S112, the management part 12 will judge whether the electronic book of the same genre as the electronic book which the user selected is less than the predetermined number of books (less than 10 books). Here, when 11 or more electronic books of the same genre as the electronic book selected by the user are read, as described in step S110, the record of the user of the genre is deleted from the worksheet. ing. Therefore, if a record of the same genre as the selected electronic book does not exist in the worksheet, the determination in step S112 is denied, and the process proceeds to step S18 in FIG. 9 without performing processing on the worksheet.

  On the other hand, when an electronic book of the same genre as the electronic book selected by the user has not been read yet, a record of the user of the genre exists in the worksheet. Therefore, in such a case, the determination in step S112 is affirmed, and the management unit 12 proceeds to step S114. In step S114, the management unit 12 determines whether or not the selected electronic book is an electronic book to be newly read. That is, the management unit 12 determines whether the ID of the selected electronic book is not included in the user record in the reading history DB 22. If the determination in step S114 is negative, that is, if the selected electronic book is not an electronic book to be newly read, the management unit 12 proceeds to the process of step S18 in FIG. In step S116, the process proceeds to step S116. In step S116, the management unit 12 adds +1 to the total number of books in the genre of the selected electronic book in the user's record in the worksheet, and proceeds to the processing in step S18 in FIG.

  Returning to FIG. 9, when the process proceeds to step S <b> 18, the management unit 12 acquires the previous interruption page and interruption date / time from the reading history DB 22. For example, when the user with the user ID = 001 selects the electronic book ID = S123-01, the latest interruption date “13/10/14 22:00” is acquired as the interruption date, and the interruption page is obtained. “50” is acquired. In addition, when the user selects an electronic book to be newly read, the history of the electronic book does not exist in the reading history DB 22. Therefore, in this case, the management unit 12 acquires “first page” as the interrupted page, and does not acquire information on the interrupt date and time.

  Next, in step S20, the management unit 12 determines whether or not the interruption date / time has been acquired in step S18. If the determination in step S20 is negative, the process proceeds to step S24, and the management unit 12 displays the browsing screen data of the electronic book data of the acquired interrupted page (here, the first page) on the user terminal 70 (display). To the processing unit 72). When receiving the browsing screen data, the display processing unit 72 displays the browsing screen of the first page on the display unit 193 as shown in FIG. Thereafter, the process proceeds to step S44 in FIG. In addition to the electronic book data, the “browse reading” button, the “previous page” button, and the “next page” button are provided on the browsing screen.

  On the other hand, if the determination in step S20 is affirmative, that is, if the interruption date and time can be acquired, the management unit 12 proceeds to step S22, and whether the genre of the selected electronic book is in the return DB 20 for each user. Determine whether. When the determination in step S22 is negative, the management unit 12 proceeds to step S24, and transmits the acquired browsing screen data of the interrupted page to the user terminal 70 (display processing unit 72). In this case, the display processing unit 72 displays the browsing screen of the interrupted page (for example, 50 pages) on the display unit 193 at the timing when the browsing screen data is received, for example, as illustrated in FIG. Thereafter, the process proceeds to step S44 in FIG.

  On the other hand, if the determination in step S22 is affirmative, that is, if the genre of the selected electronic book is included in the user record in the return DB 20 for each user, the process proceeds to step S26. If transfering it to step S26, the management part 12 will display the browsing screen data which added the "return to the place which seems to be able to remember" button as a 1st button to the electronic book data of the acquired interruption page to the user terminal 70 (display process). Part 72). In this case, the display processing unit 72 receives an interrupted page (for example, page 50) to which a “return to a place where it can be remembered” button is added as shown in FIG. A browsing screen is displayed on the display unit 193.

  Next, in step S28, the management unit 12 determines whether or not the pressing information of the “return to a place where it can be remembered” button is received within a predetermined time (for example, within several tens of seconds). If the determination in step S28 is negative, the management unit 12 transmits to the user terminal 70 (display processing unit 72) browsing screen data in which the “return to a place where it can be remembered” button is deleted in step S29. Then, the process proceeds to step S44 in FIG. In addition, the display process part 72 displays a browsing screen as shown in FIG. 14A on the display part 193 at the timing which received browsing screen data, for example. On the other hand, if the determination in step S28 is affirmative, that is, if the user presses the “return to a place where it can be remembered” button via the input unit 195, the process proceeds to step S30.

  In step S30, the management unit 12 calculates an elapsed time from the previous interruption date and time to the current activation time. Next, in step S <b> 32, the management unit 12 acquires the average number of return pages corresponding to the calculated elapsed time from the user-specific return DB 20. For example, when a user with a user ID = 001 browses an electronic book of the genre “Novel” for the first time in seven days, the management unit 12 refers to the return DB 20 for each user in FIG. “2 pages” is acquired as the number of pages. Thereafter, the process proceeds to step S40 in FIG.

  When the process proceeds to step S40 in FIG. 11, the management unit 12 adds the acquired average return page number to the total return page number of the return DB 20 for each user and increments the total number by one. Next, in step S42, the management unit 12 uses the “return to the first opened page” button as the second button and the electronic book data of a page (for example, 48 pages) returned from the interrupted page by the average number of returned pages. Is transmitted to the user terminal 70 (display processing unit 72). The display processing unit 72 displays a browsing screen as shown in FIG. 15 on the display unit 193 at the timing when the browsing screen data is received.

  Next, in step S44, the management unit 12 stands by until any button press information is received. That is, the management unit 12 stands by until the user presses any button displayed on the browsing screens of FIGS. When the user presses any button, the management unit 12 proceeds to step S46, and the management unit 12 determines whether or not the user has pressed the “return to first opened page” button. If the determination in step S46 is negative, the process proceeds to step S50, and the management unit 12 displays the screen of a predetermined time (FIG. 13B, FIG. 14A, FIG. 14B, or FIG. 15). It is determined whether or not the previous page button was pressed within a few tens of seconds). If the determination in step S50 is negative, the process proceeds to step S54, and the management unit 12 displays a predetermined time (the screens of FIGS. 13B, 14A, 14B, and 15). It is determined whether or not the next page button was pressed within a few tens of seconds). If the determination in step S54 is negative, the management unit 12 determines in step S58 whether or not the previous page button or the next page button has been pressed after a predetermined time. If the determination here is negative, the user has pressed the “end reading” button. Therefore, after executing the process of step S62, the management unit 12 performs all the processes in FIGS. Exit. The process of step S62 will be described later.

  Hereinafter, processing when the user presses each button will be described.

(When the user presses the “Return to first opened page” button)
When the user presses the “return to first opened page” button, the determination in step S46 is affirmed, and the management unit 12 proceeds to step S48. In step S48, the management unit 12 transmits the browsing screen data displaying the interrupted page to the user terminal 70 (display processing unit 72). The display processing unit 72 displays the browsing screen (see FIG. 14A) on the display unit 193 at the timing when the browsing screen data is received. Thereafter, the process returns to step S44.

(When the user presses the “Previous Page” button within the specified time)
When the user presses the “Previous page” button within a predetermined time, it means that the user needs to go back further than the currently displayed page in order to confirm the contents up to the interrupted page. . In this case, the determination in step S50 is affirmed, and in step S52, the management unit 12 executes a sub-page button processing subroutine in time. In step S52, the process according to the flowchart of FIG.

  In the process of FIG. 12A, the management unit 12 determines whether or not the genre of the electronic book selected by the user is in the return DB 20 for each user in step S150. When the determination in step S150 is affirmed, the process proceeds to step S152, and the management unit 12 calculates the average return page by adding 1 to the total return page and the total number of the return DB 20 for each user. Here, it is assumed that the management unit 12 calculates the elapsed time from the previous interruption date and time to the activation and updates the record corresponding to the elapsed time. Note that the management unit 12 has already incremented the total number of the return DB 20 by user in the processing after step S10 of FIG. 9 (when the total number has already been incremented by +1 since the start of reading this time). In this step S152, the total number of times is not incremented by one. On the other hand, if the determination in step S150 is negative, the process proceeds to step S154, and the management unit 12 calculates the average return page by adding 1 to the total return page and the total number of times in the work table (FIG. 8). Also in this case, the management unit 12 calculates the elapsed time from the previous interruption date and time to the activation time, and updates the record corresponding to the elapsed time. If the total number of work tables has already been incremented by +1 in the processing after step S10 in FIG. 9, the management unit 12 does not increment the total number of times by this step S154. When the elapsed time has already been calculated before step S152 or S154 (for example, after step S30), the elapsed time may be used in step S152 or S154.

  After step S152 or S154, the process proceeds to step S156, and the management unit 12 transmits the browsing screen data displaying the previous page to the user terminal 70 (display processing unit 72). The display processing unit 72 displays the browsing screen of the previous page at the timing when the browsing screen data is received. Thereafter, the process returns to step S44 of FIG.

(When the user presses the “Next Page” button within the specified time)
When the user presses the “Next Page” button within a predetermined time, the user did not have to go back to the currently displayed page to confirm the contents up to the interrupted page (displayed) Means that the page has gone too far back). In this case, the determination in step S54 is affirmed, and the management unit 12 executes a subroutine for the next page button within time in step S56. In step S56, the process according to the flowchart of FIG. 12B is executed.

  In the process of FIG. 12B, the management unit 12 determines whether or not the genre of the electronic book selected by the user is in the return DB 20 for each user in step S160. When the determination in step S160 is affirmed, the process proceeds to step S162, and the management unit 12 decrements the total return page of the user-specific return DB 20 by -1, and increments the total number by one to calculate an average return page. To do. In this case, it is assumed that the management unit 12 calculates the elapsed time from the previous interruption date and time to the start-up time, and updates the record corresponding to the elapsed time. Note that the management unit 12 does not increment the total number in this step S162 when the total number of the return-by-user DB 20 has already been incremented by +1 in the processing so far in this reading. On the other hand, when the determination in step S160 is negative, the process proceeds to step S164, and the management unit 12 decrements the total return page of the work table (FIG. 8), decrements the total number of times, and sets the average return page. calculate. Even in this case, the management unit 12 calculates the elapsed time from the previous interruption date and time to the activation time, and updates the record corresponding to the elapsed time. Note that the management unit 12 does not increment the total number of times in step S164 when the total number of work tables has already been incremented by +1 in the processing so far in the current reading. When the elapsed time has already been calculated before step S162 or S164 (for example, after step S30), the elapsed time may be used in step S162 or S164.

  After step S162 or S164, the process proceeds to step S166, and the management unit 12 transmits browsing screen data displaying the next page to the user terminal 70 (display processing unit 72). The display processing unit 72 displays the browsing screen of the next page at the timing when the browsing screen data is received. Thereafter, the process returns to step S44 of FIG.

(When the user presses the “Next Page” button or the “Previous Page” button after a predetermined time)
The case where the user presses the “next page” button or the “previous page” button beyond a predetermined time means a case where a normal page turning operation is executed. In this case, the determination in step S58 is affirmed, and the management unit 12 transmits the browsing screen data displaying the next page or the previous page to the user terminal 70 (display processing unit 72) in step S60. The display processing unit 72 displays the browsing screen on the display unit 193 at the timing when the browsing screen data is received. That is, the normal page turning operation by the user reading the electronic book is enabled by the process of step S60. Thereafter, the management unit 12 returns to Step S44. In addition, the “Next Page” button is pressed when reading in normal reading, but the case of pressing “Previous Page” here is a page other than the purpose of going back to what you remember It means return (eg, confirmation of characters).

(When the user presses the “Reading End” button)
When the user presses the “end reading” button, the determination in step S58 is denied, and the management unit 12 proceeds to step S62. In step S62, the management unit 12 records the number of pages on which the “reading end” button is pressed and the date / time in the “interrupt page” and “interrupt date / time” fields of the reading history DB 22, and performs all the processes in FIG. 9 to FIG. Exit.

  As described above, in this embodiment, the user-specific return DB 20 and the worksheet can be updated while the user is reading the electronic book (FIG. 10, steps S40, S152, S154, S162). , S164). In the present embodiment, the management unit 12 realizes functions as a first display control unit, a second display control unit, a third display control unit, and an acquisition unit.

  As described above in detail, according to the present embodiment, the management unit 12 stores in the reading history DB 22 the page (interruption page) that was last displayed by the user when viewing the electronic book and the discontinuation date and time. (S62) If there is a request to browse the electronic book again (S14: affirmative), the user receives screen data including the electronic book data of the previous interrupted page and a “return to a place where he can remember” button. When it is transmitted to the terminal 70 (S26) and the pressing information of “Return to a place where it can be remembered” is received (S28: Yes), the page returned by the number of pages corresponding to the elapsed time from the previous interruption date and time to the startup is returned. A browsing screen is displayed (S30, S32, S42). As a result, when reading is resumed, the user can browse a page that has been returned by the number of pages corresponding to the elapsed time by pressing a “return to a place where it can be remembered” button. In this case, the user can view the page returned by an amount appropriate for remembering the contents read before the interruption by returning the amount corresponding to the interruption time and displaying it. This makes it easier for the user to remember the content that was being read before the interruption, thereby improving usability.

  Further, in the present embodiment, when the user presses the “return to a place where it can be remembered” button, the “return to first opened page” button is displayed together with the contents of the page returned by the number of pages corresponding to the elapsed time. Is displayed on the browsing screen. In this embodiment, when the “return to first opened page” button is pressed, the page that was last displayed at the time of interruption is displayed on the browsing screen. As a result, even when the user goes back to the page, the user can return to the last page displayed at the time of interruption by pressing the button once. That is, it can be said that the usability of the user is improved from this point.

  Moreover, in this embodiment, the management part 12 calculates | requires the tendency (average return page number) to go back from the page where the user who started browsing of an electronic book was displayed for every user and every elapsed time from interruption, Used for display processing. Thereby, it is possible to perform an appropriate browsing screen display process in consideration of the user's reading tendency.

  Moreover, in this embodiment, the management part 12 calculates | requires the tendency (average return page number) to go back from the page where the user who started browsing an electronic book was displayed for every genre and every elapsed time from interruption, Used for display processing. Accordingly, it is possible to perform appropriate browsing screen display processing in consideration of the reading tendency for each genre.

  In addition, although the said embodiment demonstrated the case where an electronic book display apparatus was a server, it is not restricted to this. For example, the electronic book display device may be the user terminal 70. That is, in the user terminal 70 in which the electronic book display program is installed, the return DB 20 for each user is held (only the user data of the user terminal 70 may be stored), and the user browses the electronic book. In addition, a “return to a place where it can be remembered” button is displayed, and when the button is pressed, the page may be returned by an amount corresponding to the elapsed time. In this case, the electronic book is not limited to an electronic book lent from a library, but may be a purchased electronic book.

  In the above embodiment, in the return DB 20 for each user, the average number of return pages is managed by dividing the elapsed days into “1 day to”, “3 days to”, “7 days to”, and so on. Although explained, it is not limited to this. That is, the elapsed days classification may be different from the above.

  In the above embodiment, data such as the average return page is managed by the worksheet until the predetermined number (for example, 10) of electronic books of the same genre is read, and the data such as the average return page is stored in the return DB 20 for each user. Explained the case of not migrating. However, the present invention is not limited to this, and the management unit 12 may not use a worksheet in the processes of FIGS. In this case, by not using the worksheet, data such as the average number of return pages is stored in the return DB 20 for each user from the stage of browsing the first book of each genre.

  In the above embodiment, for example, when the “return to a place where you can remember” button is pressed on the browsing screen of FIG. 14B, the “return to the first opened page” button is displayed as shown in FIG. The case of displaying was explained. However, the present invention is not limited to this, and the “return to the first opened page” button may not be displayed. Further, it is preferable not to display the “return to the first opened page” button when the “return to first opened page” button is displayed and the process proceeds to read and the “first opened page” is reached.

  In addition, although the flow (especially FIG. 11) in the said embodiment has described operation | movement so that the movement to the first opened page may become clear, after reaching the first opened page, step is performed. In step S56, the previous page is displayed when the previous page button is pressed, and the next page is displayed when the next page button is pressed, regardless of the predetermined time. It is preferable to become an operation.

  In the above embodiment, the case where the average return page number is managed for each user, genre, and elapsed days has been described. However, the present invention is not limited to this, and the average return page number should be managed at least for each elapsed day. . For example, when managing the average number of return pages for each genre and number of elapsed days, a return DB as shown in FIG. 16 may be used. In addition, the average return for each element (eg, generation (see FIG. 6A)), reading start time (morning, noon, evening, etc.), publisher, font size, etc. The number of pages may be managed.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the processing apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium (except for a carrier wave).

  When the program is distributed, for example, it is sold in the form of a portable recording medium such as a DVD (Digital Versatile Disc) or a CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.

  The above-described embodiment is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
