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 store code information output from an OATA device such as a word processor or a personal computer as it is.

When storing code information or image information in the optical disk device 17, it is necessary to determine whether the input information is code information or image information. As this determination means, for example, a display indicating whether the information inputted is code information or image information is displayed on the screen of the CRT display device 26, and the operator selects either one of these information on the keyboard 13. This is done by instructing by key operations or by operating the mouse 14 to move a cursor on the CRT display device 26, and by using the CPLJ 12 to determine which information is indicated by the cursor.

On the other hand, when storing code information and image information in the optical disc 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.

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.

Furthermore, a maximum of 20 items of 1, K2, and K3 can be set as the plurality of key information forming the search title T.

That is, Kn is the number of keys in the title structure TT, ) (na, T1, T2, Cn are the key names for each key information, type 1 (numeric value, character 2, kanji attributes), type 2 (variable length, fixed length attribute), number of digits.

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 BG consisting of a plurality of binders B, and a search title T1 and an image information table PT for each binder. In addition, each binder B has a binder name 13n and a title structure T.
T1 consists of 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.

Further, the code information can also be stored on the optical disc in a state in which it is converted into uniform information.

In this case, for example, when an instruction is given to convert and register code information and image information, the code information read from the magnetic disk device 18 is first stored in the main memory 16 via the 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 uniformity information is stored in the display memory 22.

This encoded uniformity information is stored in the image information storage area 1iEi of the optical disk device 17 via the enlargement/reduction circuit 23, the vertical/horizontal conversion circuit 24, the buffer memory of the page memory 21, and the interface circuit 15.

On the other hand, by inputting the code information and aim uniform information search title stored in the optical disk device 17, it is possible to search and output. In this case, since the CPL 112 can determine whether the retrieved information is code information or uniform information depending on the storage area of the retrieved information, the operation lip side can determine whether the retrieved information is code information or not.
There is no need to be conscious of whether it is information.

Furthermore, as is well known, image information searched for can be displayed and edited on the CRT display device 26, but code information can also be edited after being converted to image information. has been done.

In this case, the code information read from the optical disc 141217 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 in this working display memory 22b,
Character fonts corresponding to the input code information are displayed one after another. This character font, ie, image information, is stored in the display memory 22a and displayed on the CRT display device 26 by the display control section 25. In this display state, well-known editing processes such as cropping, moving, and rotating a uniform image can be performed.

This l! The operation of storing the processed uniformity 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.

It is possible to configure a comprehensive electronic filing device that includes not only one piece of information but also code information.

Further, code information and image information are stored in separate storage areas on the optical disk. Therefore, when reading code information or uniformity information, it is possible to easily determine whether the read information is code information or image information, depending on which storage area it is read from. Even when displaying information, if it is code information, it is converted to 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 indicated using the keyboard 13 or the mouse 14, but the invention is not limited to this. For example, by determining the terminal where the information is input using the CPLJ 12, the code 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.
