Description

Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to an electronic filing device that processes information using, for example, an optical disc.

(Prior Art) As is well known, magnetic disks are widely used as information storage means in offices and the like.

However, as the amount of information increases, it is sometimes difficult to store all the necessary information using a small number of magnetic disks. In addition, code information and image information often coexist these days, and the storage capacity of magnetic disks is decreasing more rapidly than before.

Additionally, in the case of magnetic disks, there is generally little search information as a means of searching for information, so there is a problem in that it takes time to search for the necessary information. This is becoming more and more obvious. However, increasing the amount of search information increases the storage space for the search information stored on the magnetic disk and reduces the storage space for necessary information, which is not considered to be a good idea.

On the other hand, recently, electronic filing devices using optical disks have been developed. This optical disk has a much larger storage capacity than a magnetic disk, and its search ability is also superior. However, in this electronic filing device, only image information is stored as the information to be searched, and if code information is to be stored, it must be converted into image information. Therefore, it has been difficult to directly store code information output from an OAI device such as a word processor or a personal computer.

A display indicating whether the information to be input is code information or image information is displayed on the screen of the T-display device 26, and the operator selects either one of them by pressing the keyboard 1.
3 key operation or mouse 14
This is done by operating the cursor to move the cursor on the CRT display device 26, and determining by the CPU 12 which information is indicated by the cursor.

On the other hand, when storing code information and image information in the optical disk device 17, it is necessary to make it possible to distinguish between the code information and the image information.

Possible methods for this determination include a method in which the storage areas for code information and image information are separated in units of tracks on the optical disk, and a method in which storage areas for code information and image information are separated in units of blocks in the optical disk.

FIG. 2 shows a state in which the storage area of the optical disc OD is divided into tracks, where EC is a code information storage area and Ei is an image information storage area. The tracks can be spiral or concentric. By dividing the code information storage area Ec and the image information storage area Ei by track in this way,
When reading information stored on an optical disc, it is possible to recognize whether the information in the track is code information or image information by recognizing the track number. This also applies to the case where the storage areas for code information and image information are separated for each block.

FIG. 3 shows a search title T as search information. The search title T and the image information on the optical disc are in one-to-one correspondence by the image number Pn stored on the search title T and the image information recorded in the image information table PT. Therefore, if the search title is known, image information on the optical disc can be searched.

In the image information table PT, Ma indicates the recording start address on the optical disk, PL indicates the image length, and ps indicates the paper size.

Further, a plurality of key information K constituting the search title T

On the other hand, FIG. 5 shows a management table MT for managing the search title T, image information table PT, etc.

This management table MT is capable of managing, for example, a maximum of 800 binders, and is composed of a binder catalog BC consisting of a plurality of binders B, a search title T for each binder, and an image information table PT. Also, each binder B has a binder name 3n and a title structure TT.
, a storage address Ta for the search title T, and a storage address pa for the image information table PT, and one binder can manage up to 30,000 images.

In the above configuration, a case where image information of a document is read by the scanner 27 and stored in the optical disk device 17 will be described.

When a document is set on the scanner 27 and reading is started after setting the document size, reading density, etc. on the operation unit 27a, the image information of the read document is transferred to the interface circuit 29, C0DEC 31, and aspect conversion circuit 24. , are stored as they are in the page memory 21 via the enlarging/reducing circuit 23. When displaying this stored image information on the CRT display device 26, the display memory 22

Further, when storing the image information stored in the page memory 21 in the optical disk device 17, by setting the search title and specifying registration of the image information using the keyboard 13 or the mouse 14, for example, the page The image information stored in the memory 21 is supplied to the CODEC 31 via the enlargement/reduction circuit 23 and the vertical/horizontal conversion circuit 24, and is encoded in the CODEC 31. This encoded image information is transmitted to the enlargement/reduction circuit 23, the vertical/horizontal conversion circuit 24,
The data is stored in the image information storage area Ei of the optical disk device 17 via the buffer memory of the bass memory 21 and the interface circuit 15.

On the other hand, when inputting code information processed by a word processor or the like from the magnetic disk device 18 and storing this code information in the optical disk device 17, a search title is set as in the case of storing image information. When the code information registration instruction is given, the code information is read from the magnetic disk drive [18]. This code information is stored in main memory 16 via interface circuit 15. The information stored in the main memory 16 is stored in the code information storage area EC of the optical disk device 17 via the interface circuit 15.

Further, the code information can be converted into image information and stored on the optical disc.

In this case, for example, if you instruct the conversion and registration of code information and image information, the magnetic disk device! The code information read from 18 is first stored in main memory 16 via interface circuit 15. This stored code information is supplied to the working display memory 22b, and the character font corresponding to the input code information is read out in the working display memory 22b. This character font, ie, image information, is stored in the page memory 21. Note that this converted image information is stored in the display memory 2.
2a, it is also possible to display on the CRT display device 26 via the display control section 25.

The image information stored in the page memory 21 is sent to the C0DEC 31 via the enlargement/reduction circuit 23 and the vertical/horizontal conversion circuit 24.

7 is stored in the image information storage area E+.

On the other hand, the code information and image information stored in the optical disc M17 can be searched and output by inputting a search title. In this case, since the CPIJ12 can determine whether the retrieved information is code information or image information depending on the storage area of the retrieved information, the operator can determine whether the retrieved information is code information or image information. There's no need to be aware of it.

Furthermore, as is well known, image information retrieved and output can be displayed and edited on the CRT display device 26, but code information can also be edited after being converted into image information. ing.

In this case, the code information read from the optical disk device 17 is first stored in the main memory 16 via the interface circuit 15. The code information stored in the main memory 16 is supplied to the working display memory 22b, and the character font corresponding to the input code information is read out in the working display memory 22b. This character font, that is, image information is stored in the display memory 2.
2 a and displayed on the CRT display device 26 by the display control section 25 . In this display state, well-known editing processes such as image cropping, movement, and rotation can be performed.

The operation of storing this edited image information in the optical disk device 17 is similar to the case of converting the code information described above into image information and storing it in the optical disk device 17.

According to the above embodiment, the code information can be stored as is in the optical disk device 17 of the electronic filing device that processes image information. Therefore, the optical disc device [1
7 can be used not only as a normal image information storage medium, but also as an 0A storage medium for word processors, personal computers, etc.
The optical disk device 17 of the electronic filing device can be used as the core of these OA devices.

Furthermore, electronic filing devices that use optical disks have a larger storage capacity than magnetic disks, so they can store a large amount of information. In addition, it is possible to configure a comprehensive electronic filing device that includes code information.

Further, code information and image information are stored in different storage areas on the optical disk. Therefore, when reading code information or image information, it is possible to easily determine whether the read information is code information or image information, depending on from which storage area the read information is read. Even when displaying information, if it is code information, it is converted into image information and displayed. Therefore, when searching or displaying information, the operator does not need to be aware of whether the target information is code information or image information, making it easy to search. It is.

In the above embodiment, the type of input information is specified using the keyboard 13 or the mouse 14, but the invention is not limited to this. It is also possible to determine whether information has been input or image information has been input.

That is, the magnetic disk device 1 of the interface circuit 15
If information is input from the terminal to which 8 is connected, the input information is determined to be code information, and if the information is input via the interface circuit 29, the input information is image information. If it is determined that the information is , the operator does not need to be aware of the type of information when inputting the information, and the operability becomes even better.

It goes without saying that various other modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As described in detail above, according to the present invention, even when code information is input as search information in addition to image information, sufficient storage capacity can be achieved by storing code information on the optical disk by the control means. Thus, it is possible to provide an electronic filing device that is capable of obtaining information, has excellent search efficiency, and can easily store and retrieve code information.
