BRIEF SUMMARY
TECHNICAL FIELD

This invention relates to a simple electronic file system for storing documents readily in optical disks.


BACKGROUND ART

Recently, copying machines are at hand in every office, and necessary documents can be readily copied. Resultantly, offices are full of large volumes of copies, which causes troubles, In order to solve the troubles. efficient storage of the copies is sought. Furthermore, it has come even to the paperless system being proposed so as to expel papers out of offices. On the other hand, volumes of information are on steady increase. Access to large volumes of information is necessary for business.
Thus it is contradictorily required that large volumes of information are necessary for business, while increases of their documents must be avoided as much as possible for office environments.
One of the means for storing documents in optical disks is the electronic file system. The storage of documents in optical disks by the electronic file system can contribute to space savings.
But the conventional electronic file system requires a considerably cumbersome electronic file unit, and requires complicated registration/retrieval keys for storing documents, and full time operators. When a document stored in an optical disk is required, an input is made by keys in accordance with a complicated registration/retrieval key system to read the document, which needs full time operator' assistance.


SUMMARY OF THE INVENTION

An object of this invention is to provide a simple electronic file system which can record/store documents without using complicated registration/retrieval keys, and reproduce readily the stored documents.
The simple electronic file system according to this invention comprises a copying machine with an optical disk device including a light detecting unit for converting an optical image of a document into digital image information, an image storing unit for storing the digital image information converted from the optical image by the light detecting unit, a printer unit for printing the digital image information on a paper, an optical disk unit for recording the digital image information recorded in the optical disk contained in a replaceable (portable) optical disk cartridge, and a selection unit for selecting whether the digital image information is printed by the printer unit or not, and whether the digital image information is recorded by the optical disk unit or not; and a reproduction only optical disk including a selection unit for selecting one of the pages recorded in the optical disk in the optical cartridge to be reproduced, an optical disk unit for reading from the optical disk the digital image information of the page selected by the seelection unit, an image storing unit for storing the digital image information read by the optical disk, and a flat display unit for displaying the digital image information stored in the image storing unit.
This invention, which has the above-described structure, makes it possible to record image information of a document in an optical disk in units of pages by the copying machine with an optical disk device and reproduce in units as pages the image information recorded in the optical disk by the reproduction only optical disk device.
