It is composed of a memory or the like and can store a plurality of pages of the table of contents and the text read from the external recording medium 9. R
The AM 6 is composed of an IC memory or the like, and stores common display control information, which will be described later, read and extracted from the external recording medium 9.

The VRAM 8 is directly connected to the display 7 to refresh the display. The display 7 is composed of a liquid crystal display or the like. The external recording medium 9 is a floppy disk, a CDROM, an IC card, or the like. The reading device 10 reads the recorded contents according to the external recording medium 9.

The external recording medium 9 has display information (display data) such as characters, images and graphics to be displayed.
In addition, information (data) that is not directly displayed but is mixed with display control information (display control data) used when displaying display information is stored in advance for each page. The display control information is for laying out a display screen by specifying the size of characters when displaying the display information, vertical writing / horizontal writing, character-to-character spacing, line spacing, prohibition processing, and the like. The display position of an image is designated.

The display control information is inserted as a control tag <...> In the text characters of the body, and this portion is treated as being not displayed. Control tags are vertical writing, horizontal writing,
There are character size, line spacing, character spacing, etc., and examples thereof are shown in FIG. Generally, one control tag is <...>
Start with and end with </ ・ ・ ・. The range between these two control tags becomes effective. However, there are some cases where </-> indicating the end is unnecessary (see FIG. 3).

Next, an example in which such a control tag is included in the text of the body is shown below.

(Example of text) <Common><Verticalwriting><Line spacing, 10><Character spacing, 2><
Full-width></Common><Double-width> Bocchan Natsume Soseki </ Double-width><Page><Horizontal> Preface The short story "Bocchan" was first published in the magazine "Hototogisu" in April 1989. . At this time, "Hototogisu" was serialized by Soseki's popular work "I am a cat," and in this issue, "Botchan" and "I am a cat, Chapter 10" were published together. . However, at that time, Soseki Natsume was a university lecturer in English and English literature, and was still an amateur writer. The stage of the work is Matsuyama City, Ehime Prefecture, in the 18th year of the Meiji era. In other words, it is already a classical work from a modern perspective, but it was read as a novel at the time of its release. In addition, Soseki was actually a teacher at the Ehime prefecture ordinary junior high school (Matsuyama junior high school) when he was 29 years old in 1918. So, this work strongly reflects the actual experience of Soseki himself. <Page><Verticalwriting><Doublesize> Chapter 1 </ Double size><Emphasistype> I have been losing money since I was a child with my parent's ironless gun. When I was in elementary school, I jumped off the second floor of the school and pulled out for about a week. "Why did you do that?"
There may be people who ask. It's not a very deep reason. This is because when he was heading out of the newly built second floor, one of his classmates jokingly said, "No matter how long you go, you can't jump off from there. Yowamushi." When he came back to the ambassador and returned, he said with a big eye, "Is there a guy who jumps down from the second floor and pulls out his waist?" answered. When I got a Western knife from a relative's and held a clean blade over the sun and showed it to my friends, one person said, "It glows but it doesn't seem to cut." He said, "I will show you if there is something that cannot be cut."<Page> In the above example, the display control information commonly used for the entire book (entire page) is stored as the common display control information, for example, only on the first page. Further, the display control information unique to each page is stored in the head portion of each page, for example. This unique display control information is used only for display control of the page as described later. Next, an example of the operation of the embodiment of the present invention having such a configuration will be described below.

In this embodiment, an external recording medium 9 such as a floppy disk is attached to the reading device 10 when used. Then, by operating the keys arranged on the input unit 4, the reading device 10 reads the display information and the display control information of the first page to several pages from the external recording medium 9 in addition to the table of contents. The read information is stored in the RAM 5 via the bus 3.

Next, common control information commonly used for each page is extracted from the information of the first page stored in the RAM 5, and stored in the RAM 6 as setting information for display control described later. (S1). Further, it is detected whether or not there is an instruction to change the display content by the page key of the input unit 4, that is, whether or not there is a page turning request (S2). When there is a page turning request, the reading device 10 reads the information of the designated page from the external recording medium 9 (S3).
