The display control unit 38 controls display on the display device 6. The communication control unit 39 controls communication with the external facsimile machine 3b and the like. Here, the facsimile machine 3b has the same configuration as the facsimile machine 3a. The reading unit 40 reads an image from a document. The recording unit 41 prints out an image based on facsimile received image data or the like. The image information memory 42 stores facsimile received image data, image data read by the reading unit 40, and the like.

The CAD data format analysis unit 43
For example, CAD data format data is extracted from data received by facsimile from the facsimile device 3b, and the data format of the extracted CAD data format data is analyzed. The CAD data conversion unit 44, for example, outputs the CAD data extracted by the CAD data format analysis unit 43.
The data is converted into facsimile image format data based on the analysis result of the CAD data format analysis unit 43. The CAD data compression / decompression unit 45 compresses the CAD data to be transmitted by facsimile and converts the CAD data received by facsimile.
The data is restored from the compressed state. The CAD data transfer control unit 46 transmits the CAD data received from the host device 1a to, for example, the facsimile device 3b by facsimile, receives the CAD data from the facsimile device 3b by facsimile, and extracts the CAD data extracted by the CAD data format analysis unit from the host device. 1a.

The facsimile device 3b connected via the communication control unit 3b is connected to the modem 2 in the same manner as the facsimile device 3a.
b to the host device 1b. Host device 1b
Is, for example, A0 size and A1
It has a function to draw large figures.

The operation when facsimile transmission is performed from the facsimile apparatus 1a having the above configuration will be described with reference to the flowchart of FIG.

The plotting is performed by the host device 1a, and CAD data representing the drawing is transmitted from the host device 1a to the facsimile device 3.
a (step S1). The facsimile device 3a converts the CAD data transmitted by the host device 1a into a host I / F3.
2 (step S2), and the CAD data compression / decompression unit 45 compresses the CAD data received from the host device 1a (step S3). As a result, the amount of CAD data to be transmitted by facsimile can be reduced, and facsimile transmission efficiency can be increased.

The user sets an instruction document and other originals such as a destination sheet on an original platen (not shown), and issues a facsimile transmission instruction of an image of the set original and CAD data received from the host device 1a from the operation display unit 33. Upon input, the reading unit 40 of the facsimile machine 3a reads images of other originals such as an instruction sheet and a destination sheet (step S4). The CAD data transfer control unit 46 attaches the compressed CAD data to the image data read by the reading unit 40 (step S5), and transmits the facsimile data to the facsimile device 3b via the communication control unit 39 (step S6). Here, if there is no image of the other document such as the instruction sheet and the destination sheet, only the CAD data may be transmitted by facsimile. As described above, since the CAD data received from the host device 1a is transmitted by facsimile,
Even if the reading unit 40 cannot read a large image such as an A0 size, it is possible to perform facsimile transmission of a large image such as an AO size.
