Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an optical disk filing apparatus.

(Prior Art) In recent years, in order to file a large amount of drawing information, an optical disk filing apparatus having a large storage capacity has been widely used.

This optical disk filing apparatus reads a large number of drawings with a paper scanner to obtain image data, and the image data is written on an optical disk by an optical disk filing control unit.

FIG. 2 shows an example of such a conventional optical disk filing apparatus. A large number of drawing information 1 are sequentially read by a paper scanner 2 to form image data, which is registered in an optical disk 4 by an optical disk filing control unit 3. It is like this.

However, although the CAD system has been widely used in recent years, even when many drawings are created by such a CAD system, as shown in FIG. 2 in the future, as shown in FIG.
The drawing information created by the CAD system 5 is drawn on the paper by the XY plotter 6, and the drawings 1 drawn and created by the XY plotter 6 are sequentially read by the paper scanner 2 and registered in the optical disk 4. It was

(Problems to be Solved by the Invention) However, in such a conventional optical disk filing apparatus, when the paper scanner 2 accurately reads the detailed drawing information 1 and attempts to register the image data in the optical disk 4, the resolution capability is improved. Therefore, there is a problem that a large amount of image information is required and the number of drawings to be registered in one optical disk 4 is reduced accordingly.

On the contrary, if the number of drawings to be registered on one optical disk is increased, the resolution capability of the paper scanner 2 is lowered, and in that case, clear drawing information is provided on the optical disk 4.
There was a conflicting problem that the data could not be read from the device.

Therefore, the CAD system 5 outputs data to the XY plotter 6 as normal vector data for giving an operation command for the XY plotter 6 to write a figure on an actual paper. The vector data given from the system 5 to the XY plotter 6 is directly converted into image data obtained when the figure drawn on the drawing is read by the optical scanner, and the image data is passed through the optical disc filing control unit 3 to the optical disc 4 If the registration is performed on the optical disk, it is possible to register clear image data on the optical disc without causing a failure in reading the image data due to adhesion of dust or dirt which is affected when the drawing is read by the paper scanner 2. become able to.

The present invention has been made based on this point of view, and the vector data output from the CAD system to the XY plotter is directly converted into image data that can be read by a paper scanner, and is registered in the optical disk device for clear printing. Another object of the present invention is to provide an optical disk filing device capable of filing drawing information.

[Structure of the Invention] (Means for Solving the Problems) The optical disk filing device of the present invention is a means for inputting vector data output from a CAD system to an XY plotter, and an XY plotter from this vector data. It is provided with a data converting means for directly converting the drawn figure into image data when read by a paper scanner, and an optical disk device for storing the output of the data converting means.

(Operation) In the optical disk filing apparatus of the present invention, the vector data output from the CAD system to the XY plotter is read by the input means into the data conversion means, and here the vector data is drawn on the paper by the XY plotter. The image data obtained by reading with a scanner is directly converted, and the obtained image data is stored in the optical disk device.

In this way, compared to the case where the figure drawn by the XY plotter from the CAD system is read by the paper scanner and the image data is registered in the optical disk device, the optical disk is electronically processed regardless of the dirt of the paper and the light condition. Image data can now be registered in, and clear image data can be registered.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. Drawing data (vector data) output from the CAD system 5 to the XY plotter 6 is directly input, and the XY plotter 6 draws based on this vector data. A vector-raster data conversion unit 7 for directly converting the drawing information obtained at the time of conversion into image data (raster data) obtained at the time of scanning by the paper scanner 2, and raster data input from the vector-raster data conversion unit 7. A paper scanner changeover switch 8 for switching between direct input of image data from the paper scanner 2 and the paper scanner changeover switch 8 is provided.
The raster data from the vector-raster data converter 7 or the raster data from the paper scanner 2 is switched to be supplied to the optical disk filing controller 3.

An output processing unit 9 such as a printer is connected to the optical disk filing control unit 3 so that the drawing information registered on the optical disk 4 can be output.

The optical disc filing control unit 3, the optical disc 4, the CAD system 5, and the XY plotter 6 have the same configurations and operations as those of the conventional example shown in FIG.

The operation of the optical disk filing apparatus having the above configuration will be described next.

The CAD system 5 calculates vector data of many drawings for the XY plotter 6 according to its built-in program,
It is designed to output.

Therefore, the vector-raster data conversion unit 7 uses this CAD
The vector data output from the system 5 to the XY plotter 6 is input, and the vector information created for drawing the XY plotter 6 is read this time by the paper scanner 2 with the drawing information 1 after drawing by the XY plotter 6. Direct conversion processing to image data obtained at that time, that is, raster data.

The raster data output from the vector-raster data conversion unit 7 is given to the optical disk filing control unit 3.

Therefore, in the optical disk filing control unit 3, the drawing number as the search key from the CAD system 5 and the optical disk 4 are used.
In response to a registration instruction to the optical disk 4, the drawing number data as a search key and the raster data of the corresponding figure are sequentially registered.

The raster data registered in the optical disc 4 can be read by the optical disc filing control unit 3 and can be output to the printer by the output processing unit 9.

Here, if the paper scanner changeover switch 8 is switched to the paper scanner 2 side, the image data of the drawing information read by the paper scanner 2 is input to the optical disk filing control unit 3 as raster data and registered in the optical disk 4. Is also possible.

A large-sized computer is used as the optical disk filing control unit 3 in the above embodiment, and a small computer that converts the vector data from the CAD system 5 into raster data by software processing is used as the vector-raster data conversion unit 7 through the LAN. The optical disk 4 may be registered, but when data is transmitted by connecting a small computer and a large computer on the center side in this way, the transmission line is exclusively used for serial transmission of raster data. It is conceivable that there is a problem that the time becomes long and data cannot be transmitted from other devices connected to the LAN.

In such a case, the paper scanner 2 and a dedicated IC are provided on each terminal input device side connected to the optical disk filing control unit 3 of the large-scale computer of the center by LAN.
It is possible to connect the vector-raster data conversion unit 7 configured by the above through the changeover switch 8 so that the paper scanner 2 and the vector-raster data conversion unit 7 share the paper scanner interface. When configured in this way, parallel data transmission becomes possible and LAN
The line occupation time can be shortened, and adverse effects on other connected devices can be avoided.

As described above, according to the present invention, the vector data output from the CAD system to the XY plotter is converted into image data that can be obtained by directly reading with a paper scanner and registered in the optical disk device. Because of this, the filing of drawing information is more efficient than in the case of scanning each drawing output from the CAD system by the XY plotter with a paper scanner to obtain image data and registering it in the optical disk device as in the past. In addition, the image data can be registered as a clear image without being affected by unclear images and noise due to dust adhesion and dirt that are likely to occur when reading drawing information with a paper scanner. .
