Abstract

PURPOSE:To perform the test of the whole of an facsimile control part with a single substance by connecting an image output part to an image input part. CONSTITUTION:Image data supplied from a general purpose interface bus(GPIB) via a general purpose interface controller(GPIC) is outputted from a terminal 28 via a parallel/serial(P/S) conversion part 45 and a modem 46 under the control of a CPU 43, and also, it is supplied from an output control part 52 to the image output part 33 via a compression/expansion circuit 44, and is displayed and outputted. The image data supplied from the terminal 28 is outputted to the GPIB 24 via the modem 46, the P/S conversion part 45, and the GPIC 40. The image data from the image input part 34 is outputted to the GPIB 24 via an input control part 53, the compression/expansion circuit 44, and the GPIC 40.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile connection device, and more particularly, to a facsimile connection device for connecting an M calculator and a facsimile machine.

In recent years, a facsimile connection device that connects a calculator and a facsimile has been developed as a device for using a facsimile not only for image communication between facsimiles but also as a remote input/output device for a computer.

However, there was a problem that the test was time-consuming.

The present invention has been made in view of the above points, and an object of the present invention is to provide a facsimile connection device that can easily perform input/output tests on its own.

[Conventional technology]

As shown in Figure 4, the conventional facsimile connection device
It! D section 11, image processing section 12. Facsimile I
Consisting of an I+ control section 13, it converts character/numeric code data supplied from a host computer 14 into image data and transmits it via a communication line 15. The image data from the facsimile 16 is converted into code data and input to the host 31 i machine 14.

[Problem to be solved by the invention]

When performing an input/output test on a conventional facsimile connection device, the communication line 15 and facsimile 16 must be disconnected in order to input and output image data (Means for solving the problem) Fig. 1 shows the principle of the device of the present invention. Show the diagram.

In the figure, the code data supplied from the host computer 111 to the main control unit 2 is code and image processing 11! 1! The image data is converted into image data in the code and image processing section 3 and is supplied from the facsimile control section 4 to the facsimile 6 via the communication line 5. and is supplied to the host divider 1.

An image output section 7 connected to the facsimile connection section 4 outputs and displays image data.

Further, an image input unit 8 connected to the facsimile connection device 4 inputs image data.

The entire test can be performed by itself, and image data input/output testing becomes easy.

〔Example〕

FIG. 2 shows a block diagram of an embodiment of the device of the present invention.

In the figure, characters from the host computer coming into terminal 21.
Code data such as numbers is supplied from the main control unit 22 to the image processing unit 23, where it is instantly converted into image data that displays characters, numbers, etc., and further converted into image data with a pixel density that corresponds to the destination facsimile machine. The main control unit 2

From 9.30, it is sent out to the communication line and supplied to the facsimile.

Further, image data from a facsimile coming in from terminals 28 to 30, respectively, is supplied to the main control unit 22 via facsimile control units 25 to 27, respectively.
is supplied to the character/number recognition unit 31, where each character/number composed of image data is converted into code data,
The obtained data is supplied from the terminal 21 to the host analyzer.

Each of the facsimile control units 25 to 27 has the same configuration,
An image output section 33 and an image input section 34 are connected via an image bus 32.

FIG. 3 shows a block diagram of one embodiment of the facsimile control section 25. As shown in FIG.

In the figure, image data supplied from a GPIB 24 is stored in a main memory 41 from a general virtual interface controller (GPIG) 40. The data is compressed by a compression/decompression circuit 44 under the control of a CPLJ 43 connected to the main bus 42, serialized by a parallel/serial converter 45, modulated by a modem 46, and then outputted from a terminal 28. The image data compressed by the compression/decompression circuit 44 is stored in an image memory 51 connected to an image bus 50, and the image bus 32 is connected to an output control section 52 which performs an output operation only when the facsimile control section 25 is in the output test mode. The image is then supplied to the image output section 33, where it is decompressed and output for display.

The image data transmission signal supplied from the terminal 28 is demodulated by the modem 46, parallelized by the parallel/serial converter 45, decompressed by the compression/decompression circuit 44, stored in the main memory 41, and transmitted through the GPIC 40 to the
It is output to PIB24. Further, image data read from a document (not shown) by the image input unit 34 and further compressed is sent to the facsimile control unit 25 via the image bus 32.
The signal is supplied to the input control unit 53 which performs input operation only in the input test mode, and is stored in the image memory from there via the image bus 50. This image data is expanded by the compression/decompression circuit 44, stored in the main memory 41, and outputted from the GPIC 40 to the GPIB 24.

By providing the image output section 33 and the image input section 34 in the facsimile connection device in this way, the terminals 28 to
77 facsimile control units 2 with four facsimile connection devices without connecting a communication line or facsimile to each
The input/output test can be performed for each of 5 to 27 image data, thereby making the input/output test easy and hassle-free.

(Effects of the Invention) As described above, according to the facsimile connection device of the present invention,
Input/output tests can be performed on a standalone basis, making testing easy and hassle-free, making it extremely useful for practical use.
