Abstract

PURPOSE:To shorten a line holding time, and to improve communication availability, by applying encoding on a bit of picture information from the same document with plural encoding systems prior to transmission, and storing each bit of encoded information in a storage part. CONSTITUTION:A document reading part 1 reads a document to be read prior to the call of a reception side, and a bit of read picture information is stored transiently in a buffer memory 2. An encoding part 3 receives the bit of picture information from the buffer memory 2, and applies the encoding on it with an MH system first, and a magnetic disk 4 stores the bit of picture information encoded with the MH system in an area A. Next, the encoding part 3 applies the encoding on the bit of picture information from the buffer memory 2 with an MR system, and the magnetic disk 4 stores the bit of picture information encoded with the MR system in an area B, and a control part 6 places the call to a reception side through a network control part 5. In this way, since the MR system is always used preferably, it is possible to perform most efficiently the transmission.
