Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic publishing, and more particularly to a publication medium as a large capacity recording medium such as a CD-ROM and a document processing apparatus using the publication medium.

[0002]

2. Description of the Related Art Recently, electronic publishing using a CD-ROM or the like has been put into practical use. In this system, in addition to character data, image data such as drawings is recorded on a CD-ROM disk, which can be searched, displayed and printed by a personal computer or the like connected to a CD-ROM drive. In electronic publishing, image data such as pictures and figures are recorded in addition to normal character data, but recently, it is recorded in a format conforming to a document description language called SGML in which character data and image data are mixed. Momentum is rising.

For example, in an electronic bulletin or the like in which a patent publication is recorded on a CD-ROM, as shown in FIG. 5, conventionally, a document printed on paper is read by a scanner and all character portions and drawing portions are image data. There are some that are recorded on a CD-ROM disc as the above, and some that record only a document as character code data (text data) and not a drawing. However, when SGML is used, character code data and image data are mixed. Therefore, it is possible to record the character portion of the document data with the character code data and the drawing portion with the image data. As a result, the amount of data recorded on the CD-ROM disc can be reduced, and since characters are recorded as character code data,
It has the feature that it is convenient for searching.

Note that SGML is described in detail in "CD-ROM multimedia data handbook" edited by Japan Electronic Publishing Association, but there is a special case that indicates the type of data, the structure of the document, the layout, etc. in the document data. By inserting the symbols, it is possible to mix character code data and image data, and to display and print in a predetermined layout.

In the format such as SGML, C
When reproducing the document data recorded on the D-ROM disc, the document data on the CD-ROM disc is read by a personal computer to which a CD-ROM drive or the like is connected and recorded on a hard disk or a floppy disc of the personal computer. Document data read by a document processing program is processed, and character data and image data are laid out to obtain readable data, which is then displayed on a display of a personal computer or printed by a printer.
Regarding the character fonts used for display and printing, those for personal computers were used for displaying, and those for printers were used for printing.

[0006]

By the way, only the document data and the image data are recorded on the publication medium of the conventional electronic publication. Therefore, when displaying on the display of the personal computer, this personal computer is used. Use the character fonts built into
When printing to a printer, use the character font built into this printer. Therefore, if you want to change the character font when displaying or printing for each document data, you need to change the character font of the personal computer or printer. Therefore, it is almost impossible to change the font of the document data. However, there is a problem that the expressiveness of the document is limited.

Further, the document formats used in electronic publishing are diverse, even if SGML is taken, depending on the type of target document. Therefore, there is also a problem that it is necessary to prepare a document processing program corresponding to each document in the personal computer and switch the document processing program according to the format of the document to be used.

Further, although the reproduced document is printed by a printer connected to a personal computer,
Since the interface of an ordinary personal computer printer is based on the Centronics specification, the data transfer speed is slow and it takes time to print.Because the personal computer transfers the print data directly to the printer, the print data There is also a problem that the personal computer is in a use state until the transfer of is finished, and the personal computer cannot be used for other work during this period.

It is an object of the present invention to provide a publication medium and a document processing apparatus which solves the above problems, makes it possible to easily change the font of document data, and perform data processing easily and quickly. It is in.

[0010]

In order to achieve the above object, a publication medium according to the present invention uses document data together with all of the character font data used in the document data, and further uses the character font data. A document processing program for reproducing the original document from the document data is recorded.

The document processing apparatus according to the present invention further comprises means for reading data from the publication medium, and when the read data is document data and character font data, the character font data is further written in the document processing program. Is read, the memory means for temporarily storing the document processing program and the character font data are used to process the document data by the document processing program stored in the memory means or an external document processing program. However, a means for reproducing the original document is provided.

[0012]

In the publication medium according to the present invention, not only the document data but also all the character font data is recorded. Therefore, when the character code is expanded into the image data at the time of reproduction,
This character font data can be read and used. Therefore, regardless of the character font of the personal computer used for reproducing and displaying the document or the printer used for printing, the character font having the optimum font and size can be used for the recorded document. Further, by recording a control code designating a character font to be used in the document data, it is possible to record a plurality of character fonts on the same publication medium and designate the character font to be used for each character.

Further, in the publication medium according to the present invention, in addition to the document data and the character font data, a document processing program for decoding the document data to develop the character font and for laying out the document is recorded. The program can be read and executed. Therefore, the description format of the document data is not limited to SGML, and data described in any document structure can be processed.

The document processing apparatus according to the present invention comprises a memory means for reading character font data from a publication medium in which document data and character font data are recorded and temporarily storing the character font data, and stores the character font data recorded in the publication medium. Since the whole is stored in this memory means and used for developing the character code data, it is not necessary to read the character font data from the publication medium for each character, and the character font data can be developed at high speed.

Further, in the document processing apparatus according to the present invention, the document processing program is read from the publication medium in which the document data, the character font data and the document processing program are recorded,
Since the data can be stored in the memory means and executed, it can correspond to document data of any format.
