Abstract

PURPOSE:To file clear drawing information by directly converting vector data to be outputted from a CAD system to an XY plotter into image data to be read by a paper scanner. CONSTITUTION:A vector-raster data converting part 7 inputs the vector data to be outputted from a CAD system 5 to an XY plotter 6 and directly converts the vector data into the image data to be obtained when drawing information 1 obtained after the XY plotter 6 executes plotting is read by a paper scanner 2, namely, raster data. The raster data as the output of this vector-raster data converting part 7 are given to an optical disk filing control part 3. Further, in the optical disk filing control part 3, a drawing number as a retrieving key and the raster data of a graphic corresponding to the drawing number are successively registered to an optical disk 4.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) This invention relates to optical disc filing production.

(Prior art) In recent years, memory capacity M has been used to file drawing information of human life.
Large optical disk filing devices are becoming widely used.

This optical disc filing device uses a paper scanner to read a large number of drawings into image data, and the image data is written onto an optical disc by an optical disc filing control section.

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

However, in recent years, CAD systems have become widely used, but even when creating a large number of drawings using such a CAD system, conventionally the drawings were created using a CAD system 5 as shown in Figure 2. XY drawing information
Drawings are drawn on paper using a plotter 6, and drawings 1 drawn and created by the XY plotter 6 are sequentially read by a paper scanner 2 and registered on an optical disc 4.

(Problem to be solved by the invention) However, in such a conventional optical disc filing device, when the paper scanner 2 accurately reads the detailed drawing information 1 and registers the image data on the optical disc 4, the resolution is low. Since scanning must be performed with improved scanning performance, a large amount of image information is required, and the number of drawings that can be registered on the second optical disc 4 is reduced accordingly.

On the other hand, if you try to increase the number of drawings that can be recorded on one optical disc, the resolution ability of the paper scanner 2 will be lowered, and in that case, clear drawing information will be transferred to the optical disc 4.
There was a contradictory problem in that it became impossible to read from.

Therefore, the CAD system 5 outputs data to the XY plotter 6 as normal vector data to give operation commands for the XY plotter 6 to write figures on 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 ski 1/, and the image data is transmitted via the optical disk filing control section 3. If the paper scanner 2 were to register the image data on the optical disk 4, reading the image data would be affected by dust or dirt, which would affect the reading of the drawing by the paper scanner 2. You will be able to do it.

This invention was developed based on this point of view, and it converts vector data input from a CAD system to an XY plotter into image data that can be read directly with a paper scanner, and then registers it in an optical disk device. An object of the present invention is to provide an optical disc filling device that can clearly file drawing information.

[Structure of the Invention] (Means for Solving the Problems) The optical disk filling apparatus of the present invention includes an input means for vector data outputted from a CAD system to an XY plotter, and an XY block is plotted on paper from this vector data. The apparatus is equipped with a data converting means for directly converting a figure drawn on a paper into image data when read by a paper scanner, and an optical disc storage for storing the output of this data converting means.

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

In this way, compared to the case where figures drawn by an XY plotter are read from a CAD system using a paper scanner and the image data is registered in an optical disk device, it is possible to electronically print an optical disk regardless of paper stains or good light conditions. It is now possible to register image data in the image data, making it possible to register clear image data.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 shows an embodiment of the present invention, in which drawing data (
A vector that directly inputs vector data) and directly converts the drawing information obtained when the xY block 6 draws based on this vector data into image data (raster data) obtained when the paper scanner 2 scans it. - It is equipped with a raster data converter 7 and a paper scanner changeover switch 8 that switches between raster data input from the vector-raster data converter 7 and direct image data input from the paper scanner 2. 4: The raster data from the vector-raster data converter 7 or the raster data from the paper scanner 2 can be switched and provided to the optical disc filing controller 3 by switching the YANA changeover switch 8.

An output processing section 9 such as a printer is connected to the optical disc filling control section 3 so that drawing information registered on the optical disc 4 can be outputted.

In addition, the optical disc filing control section 3, the optical disc 4
, CAD system 5, and XY plotter 6 each have the same structure and operation as the conventional example shown in FIG.

The operation of the optical disc filing device having the above configuration will be described next.

CAD system 5 executes X according to its built-in program.
Vector data of a large number of drawings are calculated and output to the Y plotter 6.

Then, the vector-raster data converter 7 converts this C
The vector data output from the AD system 5 to the XY plotter 6 is input, and the vector data created for 114 plots of the XY plotter 6 is then transferred to the drawing information 1 drawn by the The data is directly converted into image data, that is, raster data, obtained when read using 4-nana-2.

The raster data output from the vector-raster data conversion section 7 is then given to the optical disc filing control section 3.

Therefore, the optical disc filling control unit 3 receives the drawing number as a search key and an n recording instruction to the optical disc 4 from the CAD system 5, and sends the drawing number data as the search key and the raster of the corresponding figure to the optical disc 4. Data will be registered sequentially.

The raster data registered on the optical disc 4 can be read by the optical disc filing control section 3, and can be outputted to a printer by the output processing section 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 disc filing control unit 3 as raster data and registered on the optical disc 4. It is also possible to do so.

In the above embodiment, a large computer is used as the optical disc filing control section 3, and a small computer is used as the vector-raster data conversion section 7, which converts vector data from the CAD system 5 into raster data through software processing. However, when connecting a small computer and a large computer on the center side for data transmission, the transmission line must be connected in order to serially transmit raster data. There may be a case where the exclusive time becomes longer and the inconvenience occurs that data transmission from other devices connected to the LAN becomes impossible.

In such a case, a vector-to-raster data conversion section consisting of a paper scanner 2 and a dedicated IC is installed on each terminal input device side connected to the optical disk filling control section 3 of the large-scale computer at the center via LAN. 7
The paper scanner interface can be shared between the paper scanner 2 and the vector-raster data converter 7 by connecting the paper scanner 2 and the vector-raster data converter 7 via the changeover switch 8. When configured in this way, parallel data transmission is possible. Then,
The dedicated time of the LAN line can be shortened, and adverse effects on other connected devices can be avoided.

[Effects of the Invention] As described above, according to the present invention, vector data output from a CAD system to an XY printer is converted into image data that can be obtained when directly read with a paper scanner, Because it is registered in the device, it is more efficient than the conventional method of scanning each drawing output from a CAD system with an XY plotter using a paper scanner to obtain image data and registering it in the optical disk device. Information can be filed 1.
Furthermore, the image data can be registered as a clear image without being affected by blurred images or noise due to dust or dirt that tend to occur when drawing information is read by a paper scanner.
