Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a portable display device, particularly preferably a thin portable book, and in particular to displaying externally recorded information on a display unit such as a liquid crystal display device. It has the feature that it can display the contents of information such as different books depending on the situation.

``Prior Art'' Traditionally, books are printed with letters, numbers, symbols, drawings, tables, etc. on paper, and are sold to users. The purpose was to understand the contents of books by reading the letters, numbers, symbols, etc. And the attempt to create an electronic version of the book that corresponds to such books was a big hit (it never happened).

``Problems with the prior art'' However, this conventional book is made up of paper, and each book is made up of at least several tens of pages, but usually several hundred pages. Quite heavy, 1K per book for so-called literary novels or specialized books.
The weight had become over 100g. Therefore, when delivering Book 5 to bookstores to sell books, -a
Due to their size and weight of several tons, they are mainly delivered by truck, which increases the cost of each book due to the high shipping costs.

In addition, the size of the paper surface on which letters, numbers, symbols, etc. are printed is not standardized depending on the content, type, price, etc. of the book, and there is a problem that a considerable amount of floor space is required when storing a large amount of books.

In addition, elementary and junior high school students, whose bodies are still growing, carry heavy textbooks and other language books in their bags every day for school classes, which has a serious impact on their bodies.

This book allows you to insert text and write notes in the underlined and side sections. However, it has been impossible to compare different pages and display them on each page, or to edit other aspects based on one page.

``Means for Solving the Problems'' The present invention solves a number of the problems mentioned above and relates to a lightweight and compact display device, particularly preferably a portable display device.

The present invention provides a CD-RO? 1 (compact disk type read-only memory), a recording and reproducing device for reproducing information on this medium, a flat display section, and an information processing device for externally specifying pages to be read, etc. This is a display device that has an input key, a memory that allows arbitrary processing, and a microcomputer. Furthermore, in order to improve the functionality of such a display device, the present invention has an external input terminal for editing information using a touch pen or a light pen for processing information. Also, following external instructions,
It is also possible to include a second storage/playback device capable of recording/playing data compatible with CD ROM.

Then, the data recorded on the external recording medium is reproduced by the reproduction device, and the microcomputer displays characters, numbers, symbols, drawings, tables, etc. for one screen on the flat display device, and the user The content of the external recording medium can be grasped by reading the display screen.

"Operation" The present invention uses a recording medium such as a magnetic floppy disk, an optical disk, or a composite disk in which a magnetic memory and an optical memory are integrated, which convert characters, numbers, symbols, etc. of the contents of books etc. into code signals.

The present invention includes a display section that uses information on the recording medium as visually detected information. This display section is provided on both inner surfaces of the main body and the lid, and has the function of displaying information and detecting external input signals such as local pressure or local light from the outside. Underlining and character correction can be performed using this external local signal. Alternatively, the display on one display section (for example, the right page) may be fixed, and the other page (for example, the left page) may be configured and modified in a format required by the reader using a touch pen or a light pen. For this reason, the display device has a function of storing the information indicating 1 from the external input terminal in the IC memory within the display device, and allowing the user to display the required screen by operating the external keys when necessary.

It has one display device with these functions, that is, one playback device, and has multiple data files, and by simply exchanging them, the user can own information such as books recorded on multiple discs. It has the characteristic of becoming the same as being. Also, a normal CD-RO? External recording media such as I and the like are lightweight, weighing approximately 10 to 30 g each, and are characterized in that they do not require special equipment even when stored and transported in large quantities.

Furthermore, if the playback method of this playback device is standardized so that it can be played on any playback device, it would be possible to provide students with desks that are integrated with the playback device in educational settings such as schools.
If the machines are prepared, students will not have to carry many heavy books to school, but will only have to carry several data files weighing about 10 to 30 grams each.

Further, as the display unit of the present invention, a flat display that is as small as possible is suitable. This is because conventional displays of the CRT (cathode ray tube) type cause eye fatigue and health problems when users look at the screen for long periods of time. Therefore, a liquid crystal display is particularly preferred. A liquid crystal display has the characteristics that it causes less eye fatigue than a CRT type, is thinner, lighter, and consumes less power, and this type of display corresponds well to the purpose of the present invention. .

The present invention will be explained below with reference to Examples.

"Example 1" FIG. 1 shows an embodiment of the display device of the present invention.

FIG. 1(8) shows a front view of the folded display device in an open state, and FIG. 1(B) shows a front view of the folded display device in a folded state. In both figures, the display device main body (10) consists of a main body (1) and a lid (1'). Each has a display section (2), (2"), an external key (3), a photoelectric conversion device (5) for auxiliary power supply attached to M (1 degree), and an external storage medium playback device (4). ), external power input terminal (13), and external power/output terminal (14)
), (15).

In the case of this embodiment, a liquid crystal display device is used as the display section (2), (2''), and an optical disk, that is, a CD ROM system that records data using the difference in reflectance of irradiated light, is used as the recording medium for the data file. The photoelectric conversion device (5) employs an amorphous silicon photoelectric conversion device with a size of 20 mm x 300 mm, and the power generated by the photoelectric conversion device (5) is supplied to the charging/discharging device (16). In addition, the display device (10) is driven by charging the insufficient power from the external power source (6).

Further, the functions shown in FIG. 2 are installed inside the display device (10). This internal function is a microcomputer (
20), and if necessary, transfer and store externally recorded information to the temporary memory (17), and from this, information from any location specified by the external key (3) is randomly displayed on the display section ( 2) Display at (2°). In this display device (10), information for a screen is reproduced by operating an external key (3), and a display section (2) is displayed.

(2), and the user has the function of displaying information by reading the display. At this time, display section (2)
, (2' ”) are displayed vertically, for example, 30
Displays 50 lines of characters. A display corresponding to a certain page is displayed on the display section (2') of the lid, and a display corresponding to the next page is displayed on the display section (2). Also, compare the contents of each display. This operation can be performed by operating the input key (3) to display and read the next screen.

In this way, we were able to complete the present invention.

“Example 2” The display device used in this example is the same as in Example 1, but
The display method is slightly different.

That is, by operating the external key (3), the external recording medium 1 is
Recording and reproduction from the data file in (11) is performed simultaneously on the display sections (2) and (2'') for multiple sides.Then, the data file is stored in the memory (17) in the main body (10), and further - By the operation (3), the user's desired screen can be immediately displayed on the display unit (2) or (2°).

Further, one of the display sections is configured to detect other information from an external input terminal using a touch pen that uses local pressure or a light pen that uses local light input. For this reason, in the display section (2) or (2'), photosensors are arranged corresponding to the pixels arranged in a matrix.

Then, it is possible to rewrite part or all of the drawings and characters displayed on the liquid crystal display, or to draw an underline below the characters. Additional information edited through this external input terminal (7) is stored in the memory (17) via the microcomputer.

As a result, in the display device of the present invention, it is possible to not only read information, but also to process and edit the information.
) can now be displayed.

This method allows screens or pages that are not adjacent to each other to be simultaneously read out on the display unit, and in addition to the normal way of reading a book, it is also possible to read out processed information.

"Embodiment 3" This embodiment uses other memories shown in FIGS. 2 and 3,
This also concerns the playback function.

In FIG. 2, the first external register 1. Medium 1 (11>
, and a second storage medium 2 (11'). Furthermore, corresponding to each, one has a reproducing device (12) and the other has a recording and reproducing device (12').

As shown in Figure 3, each is a composite disk that integrates ROM and RAM into one disk (
30). That is, a first external storage medium (11) consisting of a compact disk (ROM, read only), a second external storage medium (11') provided as a part of the first external storage medium (11) (for both writing and reading purposes). ). Therefore, one of the reproducing devices (12) is a reflective ROM (read only memory) type reproducing device consisting of an optical system (13) and a light emitting/light receiving system (14). The other side is a magnetic head (16) and its drive system (16).
) RAM (write and read or random access memory) storage and playback device (
12°). For this purpose, although one magnetic head is shown in the drawings, it is also possible to use two heads, one for erasing and the other for recording or reproduction. However, the RAM capacity is smaller than that of the optical type.

This magnetic recording section is the recording surface (11) of the compact disc.
The center or outer periphery of the side, or the back side (
It may be provided in the center (top side in the drawing) or on the entire surface.

In this way, the process of information processing and issue collection performed in Example 2 and the obtained results can be stored in memory (Figure 2 (17)
), and the resulting information is stored in the recording/reproducing device (12
') to a magnetic external storage medium (11'), and can be permanently stored in 1:1 correspondence with the information (11) on the compact disc.

For this reason, the 120M information is the main information, and it is also possible to modify or correct some of the information, making it possible to use the ROM memory effectively for a long period of time.

"Effects" As mentioned above, the present invention makes it portable,
We were able to realize a lightweight, compact display device with book functions. Furthermore, since the recorded data file is lightweight and compact, it is possible to store and transport large amounts of information. 1 more
Having multiple data files for one playback device can have the same effect as having multiple books.

Further, since the display device of the present invention has two screens, it is possible to read one display part while looking at the other display part, like a double-open book. It has also become possible to make two display sections display independent displays and to compare the display contents of each. It has also become possible to process, modify, and edit displayed information on one display section while displaying a reference display on the other display section.

Furthermore, as shown in the present invention, when using a liquid crystal display device in which sensors are arranged in a matrix corresponding to each pixel of the display section, the user can touch important parts of the display screen with a touch pen or light pen, etc. By instructing
The important part can be stored in the user's memory area, or the part can be highlighted, such as underlined or reversed text, or by drawing a red line on the paper of a textbook, etc.
It is possible to provide the same function as underlining with a fluorescent pen.

Therefore, elementary and junior high school students do not need to carry many heavy books to school, but only need to carry a plurality of lightweight and compact data files. Furthermore, by incorporating an auxiliary power source such as a solar battery, it is possible to carry books and read books for a long time.

In the present invention, using the external power/output terminal shown in FIG.
You may ask for audio or music while listening to recorded information in the DROM, reading text on the display, or looking at the screen.
