(/'9 Problems to be solved by the invention
Attribute information must be input from the input means each time graphic information is converted into image information and input, which takes time and effort to store the information.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to omit the process of inputting attribute information when converting graphic information created by a CAD system or the like into image information and storing the attribute information together with the image information. It's about doing.

B.) Means for Solving the Problems The present invention provides an image information storage device that stores image information together with attribute information regarding the image information, including a receiving means that receives graphic information transmitted from another device, and a receiver that receives graphic information transmitted from another device, and a receiver that receives graphic information transmitted from another device. The present invention is characterized in that it includes a conversion means for converting the image information into image information, an extraction means for extracting attribute information from the graphic information, and a storage means for storing the image information and the attribute information.

Furthermore, the present invention is characterized by comprising an attribute information converting section that converts the attribute information extracted by the extraction means into exit candy and outputs this as attribute information.

(B) Operation Normally, drawings created using a CAD system or the like have the name of the note created for the drawing, the drawing title, etc. written in a predetermined position.

Therefore, the image information storage device of the present invention extracts such created note names and drawing titles as attribute information, and
Receive graphic information sent from devices such as systems,
It converts this into image information, extracts the above attribute information from the received graphic information, and stores the image information and attribute information.

(f) Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. (
1) is a CAD system as another device that creates drawings and holds the drawings as graphic information;
The figure information held by the system (1) includes figure identifiers (2υ, 2υ,
Position data indicating the position of the figure, coordinate displacement required for drawing the figure (however, character code if the drawing is text), parameters indicating pen number designation, etc. (including the number of parameters)
Consists of etc. For example, a drawing creation pitch name, a drawing title, etc. are attached in advance to a drawing created by such a CAD system (1) at a predetermined position, and these are also held as part of the graphic information.

(21 is a receiving unit that receives graphic information sent from the CAD system (1) to the transmission line (3), (4) is a file unit such as a magnetic disk that temporarily stores the received graphic information, (
5) is a vector raster converter that converts the graphic information stored in this file section (4) into image information, and (6) temporarily stores the image information converted from the graphic information by this vector raster converter (5). The image memory (7) stores the image information stored in the image memory (6) on an optical disk (
The optical disk section (9) stores data in the file section (4).
), (1o) is an attribute information extraction unit that extracts drawing creation pitch names, drawing titles, etc. attached to predetermined positions from the graphic information stored in the image memory (6).
) is a display section that displays the stored image information, ■ is a keyboard for inputting commands, etc., and mouth is a control section that controls the entire system. Note that the optical disc (8) stores not only image information but also attribute information extracted by the attribute information extraction section (9).

In such a configuration, when graphic information is transmitted from the CAD system (1) along with a drawing output command via the transmission path (3), the receiving section (2) receives the graphic information and transmits the graphic information. Write to file section (4).

If the receiving section (2) does not receive graphic information for a certain period of time, it determines that the reception has timed out and ends the operation of receiving a series of graphic information (in other words, - pieces of graphic information).

Incidentally, upon receiving the graphic information, the receiving unit (2) receives the graphic identifier c! of the graphic information. 1) The size of the drawing when converted to image information based on parameter factors (A according to the JIS standard)
1 version, A2 version, A6 version, etc.), and also determines the number of bytes of graphic information. Therefore, when a series of graphic information is received, the file section +41 contains the following information as shown in Figure 6. Drawing size information C1l+.

A file consisting of a graphic information string (33), which is a plurality of graphic information, is constructed, and the number of graphic information bytes is equal to the number of graphic information bytes.

This receiving operation is executed every time graphic information is transmitted from the CAD system (1), and a file as shown in FIG. 6 is constructed in the file section (4) in the order in which it is received.

Next, when the CAD system (1) transmits the completion of drawing output, the control unit α2 converts the graphic information stored in the file unit (4) into an image information number and uses the optical disc unit (7) to display the optical disk. 8).

FIG. 4 is a flowchart showing such storage operation.

First, the control section instructs the attribute information extraction section (9) to extract the drawing creation note name, drawing title, etc. from the first file in the file section (4) as representing attribute information. (Sl). Attribute information extraction unit (9
) extracts such attribute information from the first file in the file section (4) (S2). This is done by extracting graphic information (in this case, information representing characters) having predetermined position data from the file.

Next, the control section (2) instructs the vector/raster conversion section (5) to convert the graphic information in the file section (4) into image information (S6). The conversion unit (5) for vector raster conversion extracts the drawing size information (31) from the file unit (419!F+first file) and calculates the image memory size required when converting this figure information to image information. Then, an area is secured in the image memory (6).Furthermore, the vector/raster converter (5) reads out the graphic information string Q one after another based on the number of graphic information bytes (■), and converts them into straight lines,
It is converted into image information representing a circle or the like and written into the image memory (6) (S4).

When the conversion to image information is completed, the control section stores the attribute information extracted by the attribute information extraction section (9) and the image memory (6).
) is instructed to the optical disc unit (7) to write the image information stored in the optical disc (8).

The optical disc (8) is divided into an area for storing attribute information and an area for storing image information. Therefore, the optical disc section (7) stores the attribute information and image information on the optical disc (8).
(S5), thereby completing the storage operation. Thereafter, similar storage operations are performed for the second and subsequent graphic information files.

By the way, in the CAD system (1), symbols and abbreviations are sometimes used as information added to created drawings. In such a case, if the attached information consisting of such symbols and abbreviations is used as attribute information as is, it will be difficult to easily determine what the drawing is.

Therefore, it is preferable to convert such symbols and abbreviations into words that clearly indicate what they represent, and then use this as attribute information.

FIG. 5 is a block diagram showing an embodiment made in view of the above points, α3) is an attribute information conversion unit which is a feature of this embodiment, and attribute information conversion unit αJ is a CAD system (
It is equipped with a table of symbols and abbreviations used in 1) and words corresponding to these symbols and abbreviations.
) is converted into words according to a table, and these characters are output as attribute information.

Note that the other configurations and operations of this embodiment are the same as those of the embodiment shown in FIG. 1, and their explanations will be omitted.

As described above, the attribute information conversion unit (13) is not limited to converting symbols and abbreviations into characters, but also converts attribute information such as various synonyms and similar words extracted by the attribute information extraction unit. It is also possible to have a configuration in which each suitable candy is unified and output.

By doing so, when searching and reading image information stored on the optical disc (8), desired image information can be easily read out.

By the way, in each of the above embodiments, the file section (4
), the reception operation of the graphic information in the receiving section (2) and the storage operation of converting the graphic information read from the file section (4) into image information and storing it on the optical disk (8) can be performed. Can be done in parallel.

However, if such parallel operations are not required, the overall configuration can be simplified by omitting the file section (4).

(G) Effects of the Invention According to the present invention, graphic information created by another device is received using the receiving means, this graphic information is converted into image information by the converting means, and the graphic information is extracted by the extracting means. Since the attribute information is extracted from the image information and the attribute information is stored in the storage means, it is possible to use the input means when storing graphic information such as a drawing as image information without distortion or distortion along with the attribute information. There is no need to enter attribute information separately.

Further, since the attribute information extracted from the graphic information is converted into appropriate words by the conversion means, desired information can be easily read out from among the stored image information.
