Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention uses information such as literature as an electronic display means.Recently, many people have been seen reading in their vehicles using the time they spend commuting to work or school. .

However, in the morning and evening, the vehicles are often extremely crowded, so if you try to read while standing there, you can barely hold the book in one hand, and it is impossible to turn the pages with both hands. In many cases, I was unable to make effective use of my time spent commuting to and from school. On the other hand, the inside of a vehicle not only shakes but is also relatively dark, so depending on the size and font of the type, it is almost impossible to read (especially for those with poor eyesight.)

Books and the like usually have characters printed on media such as paper, so they require a lot of space to store and are sometimes inconvenient to carry. In addition, bookmarks are sometimes used to remember previously read sections.

These bookmarks also tend to come off when you carry them around, so you may not be able to remember which pages you thought you had memorized.

In the case of books, etc., there were bookmarks, but sometimes I couldn't tell which page I was reading on the left or right.

Therefore, a mark is made by some means, or a bookmark is inserted after making such a mark, but this method has the disadvantage of being inconvenient to use, such as having to carry a writing instrument at all times in order to make a mark. 0 [Object of the Invention] This invention was made to eliminate the above-mentioned drawbacks, and is capable of electronically displaying information such as documents on a display means, making it ideal for reading in a vehicle on the way to work or school. The purpose of this invention is to provide a portable information display device.

[Summary of the invention]

A predetermined key of an input means having a plurality of keys is manually used to read out corresponding information from a storage means in which information is stored in advance and display it on a display means. The display can be instructed using a key of the input means that can be operated with one hand.

〔Effect of the invention〕

It can be operated with one hand and can be displayed as appropriate by simply pressing the r+l keys, making it especially suitable for reading in a vehicle on the way to work or school.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is an input device such as a key manual device;
A control device 2 is connected to this input device 1 . This control device f12 includes a literature information storage device, for example, an information read-only storage device 3. Flat display device (e.g. dotma) IJ
Box type liquid crystal display device 41 character pattern storage device 5. A bookmark device 6 and a lighting device such as a lamp 7 are connected.

On the other hand, in FIG. 2, reference numeral 8 denotes the main body of the apparatus, and this main body 8 has a size comparable to that of a so-called paperback.

A key manual device 1 is attached to the lower end of the surface of the main body 8.
A display device 4 is provided from the center to the upper end. In this case, the key human power device 1
is the power on/off key 11, numeric keypad for specifying numbers from 0 to 9, 121 page designation key 13, and bookmark setting key 14.
．． Bookmark reading key 15. It has an illumination key 161 and a display character designation key 17, and further has a key 18 for advancing the display screen to the next page and a key 19 for returning to the previous page, which can be operated with one hand on the side surface of the main body 8. The display device 4 also has a page display section 41 at the lower corner of the screen.

Next, its effect will be explained.

First, when page designation information is input using the numeric keypad 12 and page designation key 13 of the human-powered device 1, the control device 2 reads literature information corresponding to the page designation from the storage device 3, and displays this on the display device 4. be done. Next, when you look at the next page after reading the content displayed on the display device 4, if you operate the key 18 with one hand, the control device 2 reads out the literature information corresponding to the next page from the storage device 3 and displays it on the display device 4. 4 will be displayed. Also, if you want to see the previous page, press the 19 key with one hand.
When the user operates , the control device 2 reads literature information corresponding to the previous page from the storage device 3 and displays it on the display device 4. Therefore, all of the literature information stored in the storage device 3 can be sequentially displayed on the display device 4 by appropriately operating the keys 18 and 19 in the same manner.

In this case, when using the device in a dark place where the amount of light is insufficient, such as inside a vehicle, when the lighting key 16 of the input device 1 is operated, the lamp 7 is energized and turned on by the control device 2, and the display section fI! The display contents of t, 4 are illuminated. Then, when the lighting key 16 is operated once again, the lamp 7 is turned off. Of course, in this case, if a display device that can emit light from the displayed information itself is used, the lamp 7 will be unnecessary. Further, the storage device 3 may be one that stores image data of characters or pictures and nine figures as pattern information, or one that stores code information. Here, in the case of pattern information, the pattern information is displayed directly on the display device 4 using the control bag [2].
If the pattern information has been compressed in advance, it will be displayed in its original state. In the case of code information, a character pattern is read out from the character pattern storage device 5 based on the stored contents of the storage device 3 and displayed on the display device 4. In this case, if a plurality of character patterns with different fonts and sizes are stored in the single-character pattern storage device 5, characters with the desired font and size can be displayed on the display device 4 by operating the display character designation key 17 on the input device 1. will be displayed. Of course, the control device 2I can enlarge or reduce characters without using the character pattern storage device 5.

Variations are also possible. In addition, the storage device 3

On the other hand, when using the bookmark function 1, while looking at the display on the display device 4, specify a page and a desired portion within the same page using a cursor or the like, and in this state operate the bookmark reset key 14 of the input device 1. Then, when the page and position information specified by the control device 2 is operated, the bookmark device 6 (the stored page and position information is read out and this information is also read out). Immediately, the literature information is read from the storage device 3 and the bookmarked portion is displayed on the first display device 4.

The series of operations in this case is illustrated in the flowchart of FIG.

Therefore, with such a configuration, the content of the storage device that stores literature information can be read out and displayed on the display device according to the keystrokes of the input device, and the displayed content can be advanced to the next page or the previous page. You can easily turn the book back and forth with just one-handed key operation, so you don't have to turn the pages like you would with a conventional book. This is the best place to read while reading. In addition, the displayed content can be illuminated by key operation, and the font and size of the displayed characters can be selected, making it possible to read without any problems even in dark places with insufficient light, and even for people with poor eyesight. Become. In addition, the bookmark function allows you to extract preset bookmarks from the page and position information in the document information as appropriate and display them on one display device, making it easier to bookmark the bookmarks than with conventional methods of inserting or marking bookmarks. If you can reproduce the parts, prepare a large number of them, and incorporate them into the main body as appropriate,
Since only these storage devices will be stored separately,
It requires less storage space than conventional book storage and is convenient to carry.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications without changing the gist.
