籍の内容を把握するものであった。(b) Conventional technology Conventional books are made of paper with letters, numbers, symbols, etc. printed on them and are sold to users, who are responsible for the printed characters, It was used to understand the contents of books by reading numbers, symbols, etc.
しかしながら、この従来の書籍は紙面により構成されて
おり、−冊の書籍は最低数十ページ、通常は数百ページ
より構成されているため、−冊の書籍の重Vが相当重く
、いわゆる文学小説または専門書籍では一冊あたりIK
gを越える重量になってしまっていた。そのため、書籍
を販売するために書店に書籍を配送する際には、一般に
数トン程度の重量とその大きさのため、トラックによる
配送が主であり、その配送費等がかさむため一冊あたり
のコストが高くなっていた。However, these conventional books are made up of paper, and each book is made up of at least several tens of pages, but usually several hundred pages. Or IK per book for specialized books
The weight had become over 100g. Therefore, when delivering books to bookstores for sale, they are typically delivered by truck due to their weight and size, which is approximately several tons. Costs were rising.
また文字、数字、記号等を印刷する紙面の太きさが書籍

複数画面分のデータ再生を行い、一度そのデータを再生
装置内のメモリ領域に保管しておき必要な時に使用者が
外部キー操作により必要画面を表示するほうがより使用
者が使いやすい状況となる。That is, the characters, numbers, symbols, etc. of the contents of a book are converted into code signals, the data is recorded on a recording medium such as a magnetic floppy disk or an optical disk, and this recording medium and a reproduction device that reproduces the data are used as silk. It has the function of a book. This reproducing device displays the reproduced data in a specific area of an attached display section so that the user can recognize the reproduced data. The amount of data to be reproduced may be limited to one display screen at a time, but it is possible to reproduce data for multiple screens in one playback and store that data once in the memory area within the playback device. It is easier for the user to display the required screen by operating an external key when necessary.
これら機能を有する記録媒体及び再生装置のシステムに
より、使用者は再生装置1台を有し、複数個のデータフ
ァイルを持ち、それを交換するだけで複数冊の書籍を所
有していることと同じになるという特徴を持っている。With a system of recording media and playback devices that have these functions, the user has one playback device and multiple data files, and simply exchanging them is equivalent to owning multiple books. It has the characteristic of becoming
通常の外部記録媒体は1個あたりlO〜30g程度の軽
さであり、大計の保管および運送を行っても特別な設備
を必要としないという特徴がある。Typical external recording media are light in weight, ranging from 10 to 30 g each, and are characterized in that they do not require special equipment even when stored and transported in bulk.
さらにこの再生装置の再生方式を統一して、どの再生装
