Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical disc duplicating apparatus for duplicating optical discs and a book publishing and sales system using this optical disc duplicating apparatus.

[Prior Art] In recent years, the number of newly published books has been increasing more and more, and it has become difficult for retail stores to stock the major new books due to the limited floor space. Furthermore, regarding already published books, it is completely impossible to display them on the street, except in some large bookstores.Therefore, retailers immediately return books that do not sell even if they display a large number of books, and are not expected to sell. We prioritize and display only books with high sales and bestsellers. Books that are not on display are ordered from readers.

As described above, in the current system, it is inevitable that more and more books are returned, and these returns are the cause of an increase in the price of books.

Moreover, from the perspective of readers, retail stores display only magazines and bestsellers, making it difficult for them to pick up the books they need. Furthermore, even if a book is ordered, it takes a long time to obtain it, which is extremely inconvenient for the reader.

[Problems to be Solved by the Invention] In order to solve the problems of the current system, so-called CD-ROMs and La5er Disks, which record the contents of books as electronic information instead of printing books on paper, have been developed. Electronic publishing has been proposed. However, these electronic publications need to be produced in a certain number or more, and considering the risk of unsold books, they can only be applied to books that will sell, and they are expensive.

The present invention has been made in consideration of the above points, and is an innovative product that allows retail stores to immediately respond to orders from readers for a large number of books, reduces the risk of returns, and is suitable for books with a small number of copies. An object of the present invention is to provide a book publishing and selling system and an optical disk duplicating device suitable for this book publishing and selling system.

[Means for Solving the Problems] The above purpose is to provide a reading section for reading the contents of an original optical disk on which the contents of a book to be reproduced are written, a memory for storing the contents read by the reading section, and a memory for storing the contents read by the reading section. a writing section for writing the contents stored in the memory onto the duplicate optical disk; and a writing section for sequentially reading the contents of the original optical disk and storing them in the storage section, and writing the contents stored in the storage section in the corresponding position of the duplicate optical disk. This is achieved by an optical disc duplicating device characterized by comprising a synchronizing section that synchronizes a reading section and a writing section.

Further, the above purpose is to publish an original optical disc on which the contents of the book to be published are written as a book, and to reproduce the published original optical disc as a duplicate optical disc using the above-mentioned optical disc duplication device installed in a retail store. This is achieved by a book publishing and sales system that sells books to readers, and the readers read the contents of the books by playing back the copied optical disc with an optical disc playback device.

[Function] In the book publishing and sales system according to the present invention, a book is published as an optical disc, and an optical disc duplicating device installed in a retail store copies the book and sells the duplicate optical disc. The reader reads the content of the book by playing back this duplicate optical disc using an optical disc playback device.

In addition, a display device 80 for displaying a list of books is provided at the storefront of the disc book shop 20, and a display device 80 for displaying a list of books is provided.
A list of DI or OD2 is displayed.

In this way, in the book publishing and sales system of this embodiment, the disc book shop 20 stores the original optical disc OD.
Since it is only necessary to store I or OD2, less space is required and a significantly larger number of books can be kept in stock than in the past. However, storing the original optical disc ODI or OD2 in all the disc book shops 20 for books such as books in special fields that cannot be expected to sell in very small numbers means that the disc book shops 20 that store them Very original optical disc OD
Isu is also ti for the publisher 1゜ who provides OD2! Therefore, for such books, the original optical discs ODI and OD2 are stored in the memory center 35, and the contents are sent via the communication line in response to orders from the disc book shop 2o. Make it.

That is, as shown in FIG. 1, when the disc book shop 20 requests the memory center 35 to send data of the content of the book, the memory center 35 transmits the data to the disc book shop 20 online,
The disk book shop 20 writes the sent data onto a blank optical disk OD3 and creates a duplicate optical disk O.
Create D4. Regarding the payment of the duplication fee, each disc book shop 20 may directly go to the publisher 10, or the memory center 30 may pay the duplication fee from each disc book shop 20 all at once online. good.

Next, details of the optical disc duplicating device 50 provided in the disc book shop 20 will be explained using FIG. 2. The optical disc duplicating apparatus 50 must finish copying within an extremely short period of time while the reader is waiting for the book to be delivered. For this reason, the optical disc duplicating apparatus 50 of this embodiment has only one for reading and one for writing. The feature is that each is provided with two optical heads.

An original optical disc 52, which is an original, such as original optical discs OD1 and OD2, is driven by a motor 53, and is provided with two optical heads 54A and 54B for reading. One optical head 54A reads the contents from the innermost track to the center track of the original optical disc 52,
The other optical head 54B is for reading the contents of the original optical disc 52 from the center track to the outermost track.

The head drive unit 56A that drives the optical head 54A sequentially moves the optical head 54A, which was located at the innermost circumference, toward the outside each time the contents of the track are read at the start of duplication. A head driving section 56 that drives the
