When the electronic book application program 120 is used, the OS 110 notifies the electronic book application program 120 of an event that the Reading button input 141e has been pressed. For example, the electronic book application program 120 determines whether the Reading button input 141e has been pressed for a short time or a long time by checking the duration of the notification of this event.

  The electronic book application program 120 activates the book viewer 121 and passes the book ID of the last book read from the history database 210 to the book viewer 121. The book viewer 121 opens (loads) a book corresponding to the book ID passed from the electronic book application program 120, acquires the interrupted page position associated with the book ID and registered in the history database 210, Display the page on the screen.

  When resuming reading from the reading history list, the user presses (holds) the Reading button 141e. When an event of long pressing of the Reading button 141e occurs, the electronic book application program 120 displays a reading history screen, and (of all books) the book ID of the book that has been interrupted so far, the interrupt position information, and the start of browsing Information such as date is acquired from the history database 210. Then, the acquired list of information is displayed on the reading history screen on the reading history screen in the order of browsing start date, for example, from the latest one. The electronic book metadata describes the total number of pages of the book, and the electronic book application program 120 calculates and displays the reading progress rate from the total number of pages and the interruption position information.

  When the user selects any one book from the list, the electronic book application program 120 activates the book viewer 121 and passes the book ID of the selected book to the book viewer 121. The book viewer 121 opens (loads) a book corresponding to the book ID passed from the electronic book application program 120, acquires the interrupted page position associated with the book ID and registered in the history database 210, Display the page on the screen.

  Thus, by providing the Reading button 141e as hardware, the user can operate (1) last, (2) parallel, by operating this Reading button 141e, regardless of the state of the information processing apparatus 1. Thus, it is possible to resume the reading of the book that is being read out of any of the plurality of books that are being read. The Reading button 141e may be configured as a software button displayed on the touch panel display 16.

  FIG. 6 is a flowchart showing the flow of processing when resuming browsing of an interrupted book.

  When the Reading button 141e is operated (YES in block B1), the electronic book application program 120 displays a reading history screen (block B3) if it is a long press (YES in block B2). The electronic book application program 120 acquires a list of suspended books from the history database 210 (block B4) and displays it on the reading history screen (block B5).

  When the user selects any book from the list on the reading history screen (YES in block B6), the electronic book application program 120 activates the book viewer 121 and passes the book ID of the selected book to the book viewer 121. To open the book corresponding to the book ID (block B9). The book viewer 121 acquires the interrupted page position associated with the book ID and registered in the history database 210, and displays the page on the screen (block B10).

  When the operation of the Reading button 141e is a short press (NO in block B2), the electronic book application program 120 acquires the book information that was interrupted last from the history database 210 (block B7). The electronic book application program 120 starts up the book viewer 121 and passes the book ID of the acquired book to the book viewer 121, thereby opening the book corresponding to the book ID (block B8). The book viewer 121 acquires the interrupted page position associated with the book ID and registered in the history database 210, and displays the page on the screen (block B10).

  As described above, the information processing apparatus 1 can resume browsing of a book that has been read by a simple operation.

  Here, when the Reading button 141e is pressed for a short time, browsing of the book that was interrupted last time is resumed, and when the Reading button 141e is pressed for a long time, the reading of a plurality of books being read in parallel is performed. Although an example of resuming browsing of any book has been described, the assignment of short press and long press may be reversed.

  Since the operation control processing of the present embodiment can be realized by software (program), the software is installed in a normal computer through a computer-readable storage medium storing the software, and executed. The same effect as that of the embodiment can be easily realized.
