The received signal thus received is demodulated by the modem unit 6 and expanded by the expansion unit 2. The decompressed data is stored in the first storage unit 3. When the reception confirmation switch of the input unit 22 is pressed to view the received data, the data stored in the first storage unit 3 is transmitted from the first transmission unit 4 and received by the second reception unit 23 and received by the second storage unit 21. Memorized in. The stored data is displayed on the display unit 16. If you want to print the received data, press the print switch of the input unit 22 and the first storage unit 3
The data stored in is printed on the paper by the printing unit 11. After printing, the data in the first and second storage units 3 and 21 are erased. When performing facsimile transmission, handwriting input is performed using the pen / tablet of the input unit 22, or the transmission original is read using the hand scanner unit 22, or both are input. The input data is stored in the second storage unit 21 and displayed on the display unit 16. When the transmission switch of the input unit 22 is pressed, the data stored in the second storage unit 21 is transmitted from the second transmission unit 17, received by the first reception unit 12, and stored in the first storage unit 3. The stored data is compressed by the compression unit 1, modulated by the modem unit 6 and sent to the line 14, and is printed on the paper by the printing unit 11 as a copy for transmission.

[0009]

As described above, according to the present invention, since the slave unit and the master unit are cordlessly connected, the slave unit can be moved to a desired place for facsimile communication without any restriction on the installation location. The contents can be input by handwriting without using paper, which is convenient. Further, since the transmission original can be input by handwriting and the drawing and the like can be input by the hand scanner, there is an advantage that the document and the drawing can be easily edited on one original.
