Abstract
Abstract A facsimile system has an operation controller for generating overhead information including a called party address, a demand for confirmation of recording, instructing for the transmission of a document. The document is scanned to produce binary picture data. A storage memory records the overhead information and encodes the picture data. The designated receiving party is called and the stored data is read out of the memory and transmitted, along with a demand for confirmation of the recording of the received information. As the transmitting side demands a recording confirmation response, it designates an address to which the response to the demand should be sent, which is done upon the completion of the recording of the picture signals. The facsimile machine at the initial transmitting party's station records in its recording means the contents of the response to the demand for confirmation of recording.
