2. Description of the Related Art In a CAD device, the type of a figure forming a drawing is input, and the positional relationship of the figure is input using a pointing device such as a digitizer, a mouse and a keyboard to create a drawing. The input data relating to the figure is composed of figure type and coordinate position data, and is called vector data, figure data or drawing data, and is stored in the memory device. In order to display the stored vector data, the vector data is plane-developed by a drawing processor or the like, converted into raster data, and stored in the display memory device. Raster data is also called image data. Here, in the processing of the drawing processor, coordinate conversion is performed on the coordinate position that is a part of the vector data, the address of the corresponding actual display memory device is calculated, the type of figure is decoded, and drawing is performed at the calculated address. . The vector data created by the CAD device is given a drawing name unique to the CAD device for management. The drawing name includes information such as the drawing number of the created drawing, the creator, and the creation date.

A related device of this type is, for example, Japanese Patent Application Laid-Open No. 62-205423.

On the other hand, the electronic filing apparatus inputs an original drawing from a scanner, converts it into raster data, and stores a large amount of this raster data in an optical disc. Further, raster data can be taken out from the optical disc and displayed as needed. In order to retrieve a target image from a large amount of raster data when extracting the raster data, it has a retrieval means by high-speed display as compared with a CAD device. Further, the raster data accumulated in the electronic filing device is managed by giving a drawing name unique to the electronic filing device. The drawing name is generally called a document name depending on the type of image to be stored.

As a device related to this type, there is, for example, JP-A-62-243067.

When the CAD device and the electronic filing device are connected and the vector data created by the CAD device is stored in the electronic filing device, the vector data is rasterized in order to be stored and displayed by the electronic filing device. Need to be converted to and stored.

A device related to this type of device is, for example, Japanese Patent Laid-Open No. 2-244281.

[0008]

In the above prior art, since the drawing name of the vector data created by the CAD device and the drawing name of the raster data stored in the electronic filing device are drawing names unique to each device, There was a problem that the operator had to input the drawing name to the electronic filing device when creating the data.

An object of the present invention is to convert a drawing name of vector data into a drawing name of raster data when accumulating vector data created by a CAD device and raster data obtained by converting the vector data in an electronic filing device. By accumulating, the electronic filing apparatus has a search means equivalent to that of the CAD apparatus for the raster data search means.

Another object of the present invention is to store vector data created by a CAD device and raster data obtained by converting the vector data in an electronic filing device,
By converting the drawing name of the vector data into the drawing name of the raster data and accumulating the drawing name, the drawing name input creation operation at the time of creating the raster data in the electronic filing apparatus can be omitted.

Another object of the present invention is to retrieve vector data when the vector data created by the CAD device is once stored in the electronic filing device and then taken out from the electronic filing device and the CAD device corrects the drawing. This is to provide a means for specifying vector data by searching raster data.

[0012]

To achieve the above object, in an electronic filing device connected to a CAD device, when vector data created by the CAD device is converted into raster data by the electronic filing device, it is peculiar to the CAD device. The drawing name of the vector data is converted into a drawing name unique to the electronic filing device.

[0013]

The vector data created by the CAD device is converted into raster data and stored in the electronic filing device. Accordingly, in the display search, the raster data obtained by converting the vector data into the raster data can be displayed at high speed in the electronic filing apparatus, and at the same time, the vector data corresponding to the raster data can be specified at high speed. Also CAD
Since the drawing name equivalent to the drawing name created by the device is added to the raster data accumulated in the electronic filing device, the drawing name can be searched for in the electronic filing device by using the search term in the CAD device. .

Convert to drawing name for raster data.

When the drawing name of the vector data is converted into the drawing name for raster data by the drawing name conversion device 15, the drawing name unique to the vector data input / output device 11 is converted to the drawing name unique to the raster data registration device 13.

In the drawing name conversion device 15, the amount of drawing name data of the vector data input and created by the operator from the vector data input / output device 11 is smaller than the amount of drawing name data for raster data of the raster data registration device 13, and the raster data It is automatically determined whether or not all can be stored in the area for storing drawing name data for raster data of the registration device 13, and if not, the amount of data that can be stored is reduced. When there is a sufficient area for accumulating the drawing name data for raster data, the drawing name data for raster data can be added. Further, in order to specify the vector data corresponding to the raster data, the file name of the vector data accumulated in the vector data registration device 17 is automatically given as the drawing name data for the raster data.

Further, the drawing name conversion device 15 sends the drawing name for raster data created by converting the drawing name of the vector data to the raster data registration device 13.

The vector raster correspondence device 16 defines a conversion rule for each drawing name of vector data and raster data.

The retrieval display device 14 retrieves the target drawing by displaying the drawing name and the raster data accumulated in the raster data registration device 13 at high speed. When the searched drawing is re-edited by the vector data input / output device 11, the vector data corresponding to the drawing name of the searched raster data is fetched from the vector data registration device 17 by the vector raster correspondence device 16 and is then transferred to the vector data input / output device 11.
