DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to an information processing apparatus such as a word processor, a personal computer, and a portable information terminal, and has a storage medium such as an IC card, a floppy (registered trademark) disk, and a CD-ROM storing book data. The present invention relates to an electronic book device that reads and outputs book data from an electronic book, an electronic book data processing method, and a storage medium.

[0002]

2. Description of the Related Art In recent years, a storage medium storing an electronic book and an electronic book apparatus capable of exclusively reading an electronic book have been commercialized, and the functions of information processing apparatuses have been diversified. With the increase in the storage capacity of the storage medium used in the electronic book device, how many reading data can be stored in one storage medium (CD-ROM). However, since these electronic book devices do not have a function (bookmark function) for reading from a page where reading has been interrupted, a subsequent page is separately described in a memo pad or the like to search for an interrupted portion of the book.

As a conventional technique for solving such inconvenience, for example, according to Japanese Patent Application Laid-Open No. 3-154167, when reading of an electronic book is interrupted, a reading position of displayed book data is input. There has been proposed an electronic book device with a bookmark function that can be registered as bookmark information by means of reading the book data from the storage medium and reading after the reading position registered as the bookmark information when the next reading is resumed.

[0004]

However, the bookmark function of the electronic book device disclosed in Japanese Patent Application Laid-Open No. 3-154167 does not display a bookmark mark which is inserted into a normal book, and stops reading when reading is resumed. Since the book data after the position is simply displayed, even if there are a plurality of reread portions that the user wants to read back at the time of resuming reading or during reading, the book data of the reread portions cannot be immediately read.

The present invention has been made in view of the above circumstances. For example, a plurality of bookmark data including a bookmark mark indicating a reread location of book data of an electronic book and attribute data corresponding to the bookmark mark are stored and read. An electronic book device, an electronic book data processing method, and a storage medium that can immediately display a plurality of bookmark marks and corresponding book data by selecting bookmark data corresponding to a reread portion at the time of resumption or reading. provide.

[0006]

According to the present invention, a book data storage section for storing book data, a display section for displaying book data, and at least one bookmark mark indicating a reread position of the book data are inputted. An input section for inputting attribute data to be added to each bookmark mark, a bookmark data storage section for storing the input bookmark mark and the attribute data as a pair as bookmark data, and an input section for re-reading the book data. When the corresponding bookmark data is selected, the electronic book device includes a bookmark mark corresponding to the bookmark data and a display control unit for immediately displaying book data corresponding to the bookmark mark on a display unit.

According to the present invention, a plurality of bookmark data including a bookmark mark indicating a reread location of book data of an electronic book and attribute data corresponding to the bookmark mark are stored, and the bookmark corresponding to the reread location when reading is resumed or during reading is performed. By selecting the data, it is possible to immediately display the bookmark mark of the reread portion and the book data corresponding to the bookmark mark.

[0008] The attribute data may include memo data indicating book data in a range partially specified by the input unit. According to this configuration, the relevance between the input bookmark data and the book data can be confirmed by referring to the memo data.

The attribute data may include date data of the input bookmark mark. According to this configuration, the bookmark data can be easily referred to by referring to the date data of the bookmark mark, and the book data corresponding to the input bookmark can be specified.

[0010] The attribute data may include color data of the input bookmark mark. According to this configuration, the bookmark data can be easily referred to by referring to the color data of the bookmark mark, and the book data corresponding to the input bookmark mark can be specified.

[0011] The attribute data may include a page of the input bookmark mark. According to this configuration, the page of the input bookmark mark can be confirmed.

The display control unit may be configured to receive a bookmark data list display instruction from the input unit, read out all the bookmark data stored in the bookmark data storage unit, and display the bookmark data in a selectable list. According to this configuration, the book data indicated by the selected bookmark mark can be displayed immediately by selecting the bookmark data in which all the bookmark data are displayed in a list.

The bookmark data including the memo data, the date data, and the color data may be modified, and the bookmark data storage unit may be updated and stored in the bookmark data storage unit. According to this configuration, the bookmark data stored in the bookmark data storage unit can be updated.

According to another aspect of the present invention, book data is stored using a book data storage unit, and the book data is stored using a display unit.
Displaying the book data, using the input unit, input at least one or more bookmark marks indicating the re-read location of the book data, and input the attribute data to be added to each of the bookmark marks, using the bookmark data storage unit, The inputted bookmark mark and its attribute data are stored as a pair of bookmark data, and when the bookmark data corresponding to the reread position of the book data is selected by the input unit, the bookmark data is added to the bookmark data by using the display control unit. An electronic book data processing method is provided, wherein a corresponding bookmark mark and book data corresponding to the bookmark mark are immediately displayed on a display unit.
