[Prior art]

FIG. 5 is a block diagram showing the basic configuration of a conventional information file device.

Conventional information file devices optically read image information using a scanner 1 (imaging device, generally a one-dimensional image sensor), photoelectrically convert it, and then temporarily store the digitized image data in an image memory 2. Make me remember. This image data is provided to a display memory 3 and displayed on a display device 4 such as a CRT display. After confirming the input image information on the display screen, the operator operates the keyboard 5 to input search information (title, keyword, etc.) for searching for the image information. Then, when the operator instructs information registration, the image data is output from the image memory 2 and stored in the optical disk 9, which is an information file, as well as the information regarding the storage location at this time and the previously input search information. are associated with each other and stored in a search file (RAM in the system control unit 6 or a separately installed floppy disk device, etc.).
Through the above series of processes, one item of image information is registered in the information file device.

Note that when image data is stored from the image memory 2 to the optical disk 9, the codec section 7 generally performs compression processing (encoding processing) on the data to increase the storage capacity.

Reading of registered image information is performed as follows. When the operator inputs search information such as keywords to the system control unit 6 by operating the keyboard 5, the image information is first transferred to the optical disk 9.
The above position information is read out from the search file, and image data is read out from the optical disk 9 accordingly. The read image data is decompressed (decoded) in the codec section 7 and then stored in the image memory 2.
It is given to the display memory 3 and is temporarily stored, and then it is given to the display memory 3 and displayed on the display device 4.

[Problem that the invention seeks to solve]

By the way, the development and spread of so-called office automation has been remarkable in recent years, but from the viewpoint of seeking more rationality, for example, the function of a word processor is added to the above-mentioned information file device, and documents and drawings that are registered as image information are added. etc., or adding character information to documents, drawings, etc. that have already been registered as image information, and furthermore, use as a word processor and registering document information created thereby, and document information once registered. There is a need for a device that can perform corrections, editing, etc.

However, as is clear from the explanation of the prior art described above, in the conventional information file device, documents,
When image information such as drawings is read, it is converted into a dot pattern, and thereafter all processes such as display on a display device, recording on an optical disk commonly used as an information file, and reading from this optical disk are performed. Processing is performed in the form of a dot pattern in which image data, that is, image information is broken down into pixel units and the shading thereof is digitally displayed, and is basically analog data. Therefore, it is difficult to perform processing such as adding character information expressed as a list of character codes to the data processing method of conventional information file devices, which is expressed by the shading of dots arranged in a matrix. It was hot.

The system control unit 6 is the control center of the device of the present invention, and includes a CPU (central processing unit), ROM (read-only memory storing control programs, etc. for the device of the present invention),
RAM (memory used as information file)
etc.

The codec unit 7 performs compression processing when image data stored in the image memory 2 is stored on the optical disk 9, and conversely, decompression processing when the image data stored on the optical disk 9 is sequentially outputted to the image memory 2. I do.

The optical disk 9 is a storage medium on which signals are written and read using a laser beam, and is used as a so-called information file. In the apparatus of the present invention, the optical disk 9 contains the image data compressed by the codec section 7 and the code memory 1.
It is possible to write two types of signals: code data (attached to address information) given from 1 to 1. Further, when data is read from the optical disk 9, the image data is output to the codec section 7 and expanded, and then applied to the image memory 2, and the code data is output to the code memory 11.

The image data read from the optical disk 9 and given to the image memory 2 is temporarily stored in the image memory 2 and also given to the image display memory 3, in the same way as when image information is input by the scanner 1. , is displayed as an image on the CRT display 4 via the screen composition circuit 13.

The code memory 11 sequentially stores code data input from the keyboard 5 or read from the optical disk 9, and outputs each code data to the character generator 12.

The character generator 12 generates various characters,
It is equipped with a font memory in which symbols, etc. are stored in the form of dot patterns, and the dot patterns corresponding to each character code of the code data given from the code memory 11 are read out from the font memory, and the character display which is the second display memory is carried out. Output to memory 10.

The character display memory 10 stores the dot pattern of each character given from the character generator 12, and displays the dot pattern of each character on the CRT display 4 via the screen synthesis circuit 13 according to the address information of each character. to be displayed.

The image data given to the image display memory 3 and the character data given to the character display memory 10 are displayed on the CRT display 4 simultaneously by the screen composition circuit 13, in other words, they are displayed in a superimposed manner. Is possible.

The operation of the apparatus of the present invention constructed as described above will be explained with reference to the flowcharts of FIGS. 2, 3, and 4 showing its processing procedure.

First, the information registration process will be explained according to the flowchart shown in FIG.

When registering image information, the scanner 1 is caused to read the image information to be registered. As a result, one item of image information is stored in the image memory 2 as image data. This image data is given to the display memory 3 and displayed on the CRT display 4.

If only image information is to be registered, the image information input at this point is checked on the display screen, and then the registration process described later is performed.

Now, when inputting character information, each key on the keyboard 5 is used in the same way as in a general word processor or the like. That is, when a character key on the keyboard 5 is pressed after determining the display position on the screen of the CRT display 4 through cursor control or the like, the corresponding character code is output and stored in the code memory 11.
The characters are sequentially stored in , and outputted to the character generator 12 one character at a time. At this time, the display position of the character on the screen of the CRT display 4 is detected by the address detection circuit 8, and the display position of the character on the CRT display 4 is detected by the address detection circuit 8.
It is given to the code memory 11 together with the code data as address information indicating the address on the display 4. Then, a dot pattern corresponding to the character code is given from the character generator 12 to the character display memory 10, and the address detection circuit 8
The information is displayed at the corresponding position on the screen of the CRT display 4 according to the address information given from the CRT display 4.

By repeating the above operations, character information can be created, modified, edited, etc. Furthermore, since the registration process is started immediately when the registration process is instructed, it is possible to register character information that has been created, modified, etc. up to that point at any time.

Note that the display of image information and character information on the CRT display 4 is performed via the screen composition circuit 13, so that the image information is displayed on the CRT display 4, in other words, the image information is read into the scanner 1. with the image information displayed on the CRT display 4, or with already registered image information read and displayed on the CRT display 4,
When the above-mentioned text information is input, the text information is displayed in combination with the image information. Therefore, it is possible to modify or add character information in the previously displayed image information.

Next, the registration process of each information will be explained according to the flowchart of FIG. 3.

When registration processing is instructed via the keyboard 5, a display prompting the operator to input search information is displayed. In accordance with this, the operator operates the keyboard 5 to input search information, such as keywords, titles, dates, etc. Then, the image data stored in the image memory 2 is output to the codec section 7, compressed, and stored on the optical disk 9.
is memorized.

On the other hand, when data is stored in the code memory 11, in other words, when character information is input, the code data stored in the code memory 11 and the address information representing each display position are It is stored on the disk 9 in the form of code data.

Then, the previously input search information, information regarding the storage location of the image data stored in the image memory 2 on the optical disk 9, and code data stored in the code memory 11 and its address information are transferred to the optical disk 9. The information regarding the storage location of is stored in the search file in the system control unit 6 in association with each other.

The above completes the registration of one piece of image information and the text information displayed in combination with it, but either one of the
That is, when only image information or only text information is input, each information is stored independently on the optical disk 9, and the search information attached thereto is stored in the search file, completing the registration.

Reading of each registered information is performed as shown in the flowchart of FIG.

First, an operator inputs search information such as keywords to the system control unit 6 by operating the keyboard 5 . As a result, the input search information is searched in the search file, and the corresponding image information is searched on the optical disk 9.
Information regarding the storage location above is read from the search file, and image data is read from the optical disk 9 accordingly. The read image data is decompressed in the codec section 7, then given to the image memory 2, where it is temporarily stored, and further transferred to the image display memory 3.
and displayed on the CRT display 4.

After the image information has been displayed in this manner, or when the image data corresponding to the input search information is not stored on the optical disk 9, the text information is displayed. That is, information regarding the storage location on the optical disk 9 of the code data corresponding to the input search information is read from the search file, and the code data is read from the optical disk 9 in accordance with this. The read code data is applied to the code memory 11 and temporarily stored therein, and further applied to the character display memory 10, where it is synthesized and displayed on the screen of the CRT display 4 on which the image information is previously displayed. At this time, address information regarding the display position of each character code of the code data on the screen of the CRT display 4 is also given to the character display memory 10, and each character is displayed accordingly.

At this point, the character information compositely displayed on the CRT display 4 is stored in the code memory 11.
Since it is stored in the form of code data, it is easy to modify, add to, or edit it.

〔effect〕

As detailed above, with the information file device according to the present invention, not only can documents, drawings, etc. be registered as image information in the same manner as before, but also document information can be created in the same way as with a general word processor. Furthermore, after documents and drawings are registered as image information, or once they are registered as image information, text information can be easily added to them.

Further, in this invention, since characters can be displayed in an overlapping manner at any arbitrary position of image information, arbitrary image/character editing can be performed.

Furthermore, since the registration of document information created using the word processor-like function of the device of the present invention is stored on the optical disk in the form of code data, it is easier to register documents with the same amount of characters as image information. Therefore, it is possible to register a considerably large amount of data.

In the above embodiment, an optical disk is used as a storage medium for an information file in which image information is stored as image data and document information is stored as code data. It is also possible to use a floppy disk, etc., and RAM is used as the storage medium for the search file in which search information is stored, but it is also possible to use other storage media such as those mentioned above. Of course.
