Abstract

A document data filing system used with an index data list bearing the index data associated with the document data on a plurality of documents, comprises read means for reading the document data on the document and the associated index data on the index data list, a first buffer memory for temporarily storing the document data read out by the read means, a second buffer memory means for temporarily storing the index data read by the read means, and a memory control means for applying the document data stored in the first buffer memory, together with the corresponding index data stored in the second buffer memory.

Claims

1. A document data filing and retrieval system used with an index data list bearing the index data associated with the document data in a plurality of documents to be filed, and a retrieval data list bearing the index data associated with the document data in a plurality of documents to be retrieved, comprising:

a single read means for optically reading the document data on the documents and the associated index data on the index data list and the retrieval data list;

a first buffer memory for temporarily storing the document data read by said read means;

recognizing means for recognizing the index data read by said read means;

a second buffer memory for temporarily storing the index data recognized by said recognizing means;

switch means coupling said first and second memories to said single read means for supplying said document data to said first buffer memory and said index data to said second buffer memory;

a main memory; and

memory control means for loading into said main memory the document data from said first buffer memory and the associated index data from said second buffer memory.

2. A system according to claim 1, further comprising:

a receiving section for receiving said documents and said index data list;

a transfer mechanism for transferring said documents and said index data list from said receiving section to said read means.

3. A document data filing system according to claim 1, further including retrieval means for retrieving the document data associated with the index data of the retrieval data stored in said second buffer memory from those in said main memory.

4. A system according to claim 3, wherein said retrieval means includes a comparator which compares the index data contained in the retrieval data stored in said buffer memory with the index data stored in said main memory and, when both the data are coincident with each other, produces a coincident signal;

control means which reads out the index data contained in the retrieval data stored in said buffer memory in a given order and supplies the data into said comparator while at the same time sequentially reads out the index data stored in said main memory and supplies the data to said comparator; and

means which responds to the coincident signal from said comparator to read out the corresponding document data.

5. A system according to claim 3, wherein said retrieval data further contains the data for designating the number of sheets recorded with the document data to be retrieved.

6. A system according to claim 3, wherein said retrieval data further contains the data for designating an order of reading out the document data to be retrieved.

7. A system according to claim 3, further comprising recording means for recording the document data retrieved on a sheet.
