Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a vector/facsimile conversion device for computer facsimile communication, and in particular, to a vector/facsimile conversion device for computer facsimile communication, and in particular to a method for converting signals between facsimile communication and CAD systems. The present invention relates to a conversion device that performs conversion.

B1 Summary of the Invention The present invention relates to a vector/facsimile conversion device for computer facsimile communication, which is provided between a computer and a facsimile machine and converts vector data for drawings into encoded image data for facsimile transmission. / Equipped with a facsimile conversion device, CAD drawings can be sent automatically from anywhere, improving the accuracy of drawings and providing technology that shortens sending time. 3゜C0 storage technology in recent years Facsimiles are widely used in office activities to quickly and accurately transmit various information, and combi coater communication is also attracting attention in the form of personal computer communication and e-mail. However, the two had built independent networks and were not linked. Koni/Pyuta is trying to link these two together.
This is facsimile communication.

Figure 3 is a diagram showing the horizontal structure of traps, picophones, and facsimile communication equipment, in which 31 is a computer, 32 is an adapter for facsimile communication, and 33 is a floppy disk for storing software. It's a disc. The computer facsimile communication device is often used to send documents created by an office processor or routine business data from a workstation using a facsimile. Transmit encoded information as an image using the character font installed in the computer main body or adapter 32 1
Broadly speaking, there are three types of configurations: ■Software type, ■Hardware/software combination type, and ■Hardware type.The elements that must be executed during communication are image expansion of code information and image compression (encoding). 2. The results differ depending on which one handles the execution of communication procedures, address management, etc.

The adapter 32 is only responsible for executing communication procedures in the software type ■, but in the bird/software joint type ■
In this case, it is also in charge of image expansion (7. In the hardware type ■, it is in charge of everything except destination management. Also, a dedicated processor may be used to compress the image,
Speed-up can be achieved.

However, these are all cases related to text data, and CA D (Computer Aided)
No dedicated method has been proposed for transmitting vector data handled by CAD systems, etc., and as shown in FIG.
There was no other choice but to read it with a facsimile 43 scanner, encode it, and send it. Incidentally, on the receiving side, the developing section of the facsimile 44 renders and outputs the drawing 45.

Problems that the D1 invention attempts to solve However, the method described in "-" has the following problems.

(1) After outputting the drawings using the CAD system, it was necessary to ask the person in charge of the CAD facility to send it via fax, and it could not be operated unless it was manned.

(2) Because the drawings were scanned and coded using a skiving machine, the precision of the drawings was reduced, with small characters getting crushed and lines becoming stepped.

(3) If it is impossible to separate the drawings by facsimile, they are sent by mail, which often results in long lead times.

The present invention was created in view of these problems, and
The object of the present invention is to provide a vector/facsimile conversion device that can automatically transmit CAD drawings from anywhere, improve drawing accuracy, and shorten sending time.

E0 Means for Solving the Problem The means for solving the above problem in the present invention is provided between a computer and a facsimile machine, and converts vector data for drawings into encoded image data for facsimile transmission. The vector/facsimile conversion device includes an input unit that performs transmission and reception with a drawing data creation system l, a conversion unit that converts the vector data of the received drawing into image data in a predetermined format, and a conversion unit that converts the image data into a desired facsimile system. The vector/facsimile conversion device is provided with an encoding unit that matches the above, and a communication unit that executes communication procedures and signal modulation for transmitting data over the same telephone network.

F1 Effect The present invention is intended to interpose a vector/facsimile conversion device between a computer and a facsimile machine and encode the vector dark of the drawing into image data for facsimile transmission.
