Abstract

There is disclosed a document information filing system which displays the title information and the picture information by means of single display device comprised of a cathode-ray tube. A two-dimensional scanning device is provided for optically scanning a document to be filed to produce picture information corresponding to the document. The picture information produced by the scanner is magnetically recorded on a magnetic tape of an information custody device together with a retrieval information corresponding to the picture information and comprised of a plurality of code groups. When a proper code constituting the retrieval information is set by a keyboard, the title information including this code is selected from the information custody device. On the basis of the title information, desired document picture information is retrieved and extracted. The retrieval code of the title information and the desired document picture information are selectively transmitted to a cathode-ray display by way of a gate circuit.

Claims

1. A document filing system comprising:

optical scanning means for scanning a plurality of documents randomly input thereto to produce document picture information;

means for receiving and associating with each document a retrieval character code which is determined as a function of classification parameters, each retrieval code including a predetermined parameters, each retrieval code including a predetermined number of subcodes;

memory means for storing a plurality of pieces of said document picture information and a plurality of retrieval codes corresponding thereto, each retrieval code including a predetermined number of subcodes;

a display device having a display screen bisected into a first display region for exclusively displaying retrieval code data and a second display region for exclusively displaying the document picture image;

retrieval code input means, manually operable by an operator, for specifying at least a portion of the retrieval character code; and

retrieval controller means for, when a retrieval code is at least partially specified by an operator designating one or more subcodes thereof, (a) extracting from said memory means all of those retrieval codes which include the specified subcodes as a part thereof and the corresponding pieces of document picture information, in accordance with a predetermined algorithm, (b) causing said display device to exclusively display a list of the extracted retrieval codes on said first display region ot allow the operator to select a desired document while seeing the retrieval code list, said retrieval controller means, when the operator inputs the remaining subcode or subcodes through said input means to specify a certain document, causing said display device to display a picture information of the specified document on the second display region and to continuously display said retrieval code list on the first display region, whereby, after referring to the presently displayed document picture image, the operator may select another document from those satisfying the operator'"'"'s earlier partial specification based on the retrieval codes continuously displayed on said first display region, thereby facilitating the operator to find his finally desired document whose picture information will be displayed on the second display region of said display device.

2. A document filing system according to claim 1, wherein said screen of said display device is laterally divided into left and right half areas which respectively serve as said first and second display regions and which are substantially equal in size to each other.

3. A document filing system according to claim 1, wherein said memory means includes a recording medium on which said picture information and said retrieval codes are recorded.

4. A system according to claim 1 further comprising printing means for preparing a hard copy of information displayed by said display means.

5. A system according to claim 1 wherein said memory means comprises a magnetic tape.

6. A system according to claim 1 wherein said magnetic tape comprises a continuous loop magnetic tape.

7. A system according to claim 1 wherein said memory means comprsies a magnetic disk.

8. A system according to claim 1 wherein said magnetic disk comprises a floppy disk.

9. A document filing system according to claim 1 wherein said retrieval controller means comprises:

first display control means for temporarily storing a retrieval code designated for viewing, and outputting it at a predetermined time;

second display control means for temporarily storing picture information for a document corresponding to the designated retrieval code; and

gate means, connected to said first and second control means, for selectively transferring said retrieval code and picture information to said display means.

10. A system according to claim 1 further comprising means for controlling an operational mode of said system.

11. A system according to claim 10 wherein said mode controlling means causes said system to operate in one of the following operational modes:

(1) a storing mode wherein document information is stored in said memory means,

(2) a reproduction mode wherein document information is retrieved from said memory means and displayed, and

(3) an addition/insertion/deletion mode wherein previously stored information is altered.

12. A document information filing system according to claim 1 wherein said retrieval controller means comprises refresh memory means for exclusively storing said retrieval codes in a first memory region thereof having substantially half the total memory capacity thereof and exclusively storing information of a single document picture in a second memory region having substantially half the total memory capacity thereof.

13. A document information filing system according to claim 12 wherein said display device comprises a single cathode ray tube (CRT) display.

14. A document information filing system according to claim 13 wherein said retrieval controller means comprises address designator means, connected to said refresh memory means and to said retrieval code input means, for receiving electrical character code signals originally generated by said retrieval code input means to represent the retrieval codes designated by the operator and for executing memory addressing to store said character code signals in said first memory region of said refresh memory means.
