ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electronic filing system.
2. Related Background Art
In a conventional information memory device having an information retrieving function, in the case of retrieving information, the information is retrieved by using retrieval information such as file name corresponding to where the information has been stored, a key word corresponding to the storage content, a code number added in accordance with a predetermined rule, and the like. On the other hand, the retrieval information is formed on the basis of the information designated by a keyboard or the like.
In the above conventional device, there is a problem that in the case of retrieving by using a file name, many attributes cannot be provided for one file and a variety of retrieving processes cannot be performed.
There is also a problem that in the case of retrieving by using a key word, it takes much labor to select the proper key word and a number of different words indicative of similar concepts exist, so that it is difficult to designate the proper key word upon retrieval.
There is also a problem that in the case of retrieving by using a code number, as the number of storage items increases, it becomes difficult to store the code number corresponding to the content to be retrieved, and in an actual using state, the proper code number must be selected by always referring to a conversion table.
In both of the above cases, the key operations are executed upon storage and retrieval of information and the file name, key word, and code number must be input, so that there are problems that operation skill is required and it takes a long to operate so that high working efficiency is not obtained.
To solve the above problems, as disclosed in U.S. patent application Ser. No. 417053, now U.S. Pat. No. 5,038,222; U.S. patent application Ser. No. 478250, now U.S. Pat. No. 5,363,504; U.S. patent application Ser. No. 477470, now U.S. Pat. Nos. 5,572,726 and 5,742,808, and the like, there is considered a method whereby retrieval images (stamps) indicative of retrieval information are arranged like a matrix on a CRT display screen, predetermined images are made correspond to the stamps, and the stamp corresponding to a desired image is selected from a plurality of stamps, thereby retrieving the desired image.
U.S. Pat. No. 5,038,222
U.S. Pat. No. 5,038,222 discloses an image processing system that integrates an image display unit, a document feeding path for originals, an image reading unit, and an image recording unit.
U.S. Pat. No. 5,636,504
U.S. Pat. No. 5,363,504 (referred to herein as '504) discloses an electronic filing system that reads index images from an index image memory, displays the read index images on a display that has a plurality of display locations. Each of the index images is an image representative of index information used for retrieving one or more items of image information to be stored in a storage medium. Desired index images are selected from the plurality of index images displayed at the plurality of display locations, and image information to be stored in the storage medium is inputted and stored in a vacant area of the storage medium. An index file is formed indicating a relationship between the index images selected and a storage address of the image information stored in the storage medium.
FIG. 1
is a block diagram showing a construction of an embodiment of the electronic filing system of the '504 patent. The system comprises a central processor
10
, a keyboard
15
, an opto-magnetic disk memory apparatus
21
, a liquid crystal display
23
, an image reading apparatus
25
, and an image printing apparatus
27
.
The central processor
10
includes a CPU
11
as a microprocessor, a ROM
12
in which operation programs of CPU
11
are stored, and a RAM
13
for providing a work area of the CPU
11
and a loading area for various data and programs. The central processor
10
further includes a keyboard interface circuit
14
connecting a keyboard
15
and a system bus
30
, a floppy disk device interface circuit
19
connecting a floppy disk device

connecting the image reading apparatus
25
and the system bus
30
, and an image printing apparatus interface circuit
26
connecting the image printing apparatus
27
and the system bus
30
. A clock unit
16
for keeping track of the date and time is also connected to the system bus
30
.
FIG. 2
is a schematic view of a memory area configuration of the embodiment of the electronic filing apparatus of the '504 patent shown in FIG.
1
. In the electronic filing apparatus, retrieval of an image data file group
5
is executed with directory
3
with retrieval data stored therein and a file allocation table (FAT)
4
for managing data recording addresses in a recording medium. When storing image data, the corresponding date and time are inputted from the clock unit
16
, with the date and time data being written in an empty area of the directory
3
, as shown in
FIG. 3
, and used as image identification data.
In operation, when an operator closes a power source switch (not shown), the CPU
11
executes checking of the RAM
13
, initializes internal parameters prescribed in the ROM
12
, executes initialization of the individual interface circuits, and clears the liquid crystal display
23
according to a program prescribed in the ROM
12
to be ready for operation of the keyboard
15
by the operator. Subsequently, the operator instructs the CPU
11
to read image data for registration from the keyboard
15
and sets an original image on the image reading apparatus
25
.
The CPU
11
detects, with a sensor provided in an original setting section of the image reading apparatus
25
and through the image reading apparatus interface circuit
24
, that the original is set. Then, it provides a start signal to the image reading apparatus
25
through the image reading apparatus interface circuit
24
for reading image data into the RAM
13
. Further, for providing confirmation to the operator, the CPU
11
displays the image data in the RAM
13
on the liquid crystal display
23
through the liquid crystal display interface circuit
23
.
Then, the CPU
11
receives an image reading date and time data from the clock unit
16
and stores an image discrimination code in an empty area of the directory
3
in the opto-magnetic disk memory apparatus
21
through the opto-magnetic disk memory apparatus interface circuit
20
. Further, it stores image data in an empty area of a data file in the opto-magnetic disk memory apparatus
21
. The relationship between image identification codes in the directory
3
and image data is managed by providing the directory
3
with pointers representing FAT numbers corresponding to image data memory areas.
FIG. 4
is a schematic view showing a system for managing the directory

303
, with a plurality of data storage media being provided with its own image identification codes.
FIG. 5
is a block diagram showing a construction of another embodiment of the electronic filing system of the '504 patent. The electronic filing apparatus includes an identification code setting unit
