Abstract: Preparation of Braille books and audio books by man has a problem that a great deal of costs including the work cost for recitation or translation (printing) of Braille, composition, examination and the like and the distribution cost are required as compared with general books. Further, there is a problem that books that visually handicapped people wish to read cannot be delivered immediately at an inexpensive price. The user (reader) himself participates in editing or correction in processing for producing an audio book which reads an electronic book aloud using the speech synthesis technique and pronunciation symbol text constituting the basis of the audio book to thereby reduce the cost required for the production processing of the audio book and the pronunciation symbol text and improve the quality of the audio book and the pronunciation symbol text.

Abstract: The present invention provides a commercial transaction system which enables goods to be sold and bought with high accuracy without anxiety by using a computer network such as the Internet, and which can also give credit information in commercial transaction. The electronic commercial transaction system according to the invention includes plural electronic terminals connected to one another by a computer network, and an authentication station connected to the computer network. An electronic certificate and a company code are assigned to each of the electronic terminals on the basis of examination performed by the authentication station, and when a commercial transaction is to be performed between one and another of the electronic terminals via the computer network, both selling and buying sides of the commercial transaction present the respective electronic certificates before performing the commercial transaction.

Abstract: A scanning optical device for scanning a material to be scanned with a beam emitted from a light source thereof, has a storage device for storing information relating to the quantity of deviation of a scanning optical system. The convergent position of the beams is adjustable in the direction of the optical axis by at least partially controlling the elements of the scanning optical system in accordance with information relating the quantity of deviation supplied by the storage device. The quantity of deviation such as curvature of field of the scanning optical system can be compensated by a simple structure. Therefore, a recording device or reading device employing the scanning optical system exhibiting high resolution, low cost and a capability of preventing deterioration in the gradation expression can be realized.
