Abstract

PURPOSE:To improve the manipulation of a facsimile equipment that provides data compression, by providing a two-dimensional contraction part, whose contractibility can automatically be set, between an expansion part and next compression- expansion part. CONSTITUTION:After original picture information from readout part 1 is compressed and stored in memory part 7B, a party-side terminal device is called and on the basis of information from the party-side terminal device, system control unit SCU9 decodes the paper width. number of bits of one line, etc. Decoded functional information is sent to two-dimensional contraction part 8 as a set signal for contraction-size assignment and, at the same time, supplied to data compression-expansion part DCR3 in the form of the number of bits of one line. Next, modem training is started and on the end of the training, picture information stored in memory part 7B is read out and expanded by expansion part 7C to obtain the original picture information. Then, it is compressed again into a picture of contractibility assigned by two-dimensional contraction part 8 and then sent out to the party side via DCR3 and CCU5.
