2. Description of the Related Art Law, history, ancient documents, reference materials, documents,
With regard to books produced in the past such as academic papers, it is preferable that the contents of the books are preserved in the state in which they were produced without changing the contents in the future. Here, these books are referred to as information storage type books for convenience.

These information-storing books include a book in which book contents are electronically created as text information and electronic data can be used as the original as it is, and a book in a form that can be used only in a printed state. is there. In an electronic book system that enables operations such as search and reference of book data on a computer, when simultaneously handling data formats of these two types, text data can be used as it is, but page data Regarding (image data), it is necessary to code the image data by OCR reading or input operation from the keyboard.

In order to handle book data on a computer, data tagging is applied to data in each state to structure information (structure as a book).
It is necessary to add the tag data to the data in order to add the jump destination information to the reference point.

[0005]

As described above, in the past, in order to handle the data coded from the text data and the image data, which are the original book data, on the computer, the structure and reference points of the book are changed. The tag data is added to the original book data for the purpose of adding the jump destination information. However, adding these tag data to the original book data means changing the contents of the original book data. This is not desirable for books that should be preserved as they were when created without modification.

Further, in order to add this kind of tag data to the image data (paper surface data), the image data is coded by OCR reading or input operation from the keyboard.
Since the error is easily generated by the encoding process (input process by the keyboard etc.), it takes a lot of effort to correctly encode the data, and it is impossible to completely eliminate the error. Can be said. In addition, the data created by performing the above-described encoding process becomes secondary information with respect to the original information, and the reliability of the information decreases.

The present invention eliminates the above-mentioned conventional drawbacks and enables data operations such as retrieval, reference, and memo writing of original data without directly changing the original data of a book consisting of text data and image data. It is an object of the present invention to provide an electronic book system that

Further, according to the present invention, since it is not necessary to directly change the original data itself, it is not necessary to code the original data, and it is possible to prevent deterioration of reliability due to secondary information. The purpose is to provide a system.

[0009]

In order to achieve the above object, an electronic book system of the present invention includes an original book data file for storing original book data including text data and image data obtained by digitizing the contents of a book. An access information file for performing an information search for the original book data in the original book data file, and a search processing unit for executing a search for the original book data based on the access information file. Is

The search processing means determines whether or not the element data specified to be searched is set in the structured file, and when the element data is set, the search processing means stores the element data based on the corresponding structure information. The original book data including the original book data is read from the original book data file, and the original book data serving as reference information of the element data is read by the reference link file. Searches based on the original book data as reference information has a configuration for reading from the original book data file.

According to a second aspect of the present invention, in the electronic book system, a sticky note information file storing memo information to be added to an arbitrary position on the screen with respect to the original book data displayed on the screen and the memo information are added. An individual information link specifying the position information on the screen of the original book data to which the original book data file name, the sticky note information file name, and the memo information are added, and the storage position information of the memo information in the sticky note information file. It is characterized by having a file.

In the electronic book system of the present invention according to claim 3, when the original book data is text data, the number of characters from the first character of the element data is the original book of the element data of the structured file. When the original book data is image data, the coordinate information of the area surrounding the element data is specified as the position information of the element data of the structured file on the original book data. Is characterized by.
