摘要： A recording apparatus comprises a recording medium, a recording unit disposed in proximity to the recording medium for effecting recording on the recording medium by application of a voltage thereto, a first power source providing a voltage to be applied when recording is effected on the recording medium by the recording unit, a first switching unit provided between the recording unit and the first power source and being switchable in accordance with a voltage applied to its control terminal, a second power source having one end thereof connected to the junction between the switching unit and the first power source and effective to determine the voltage of a control signal applied to the control terminal, and an isolator for receiving recording signals to be applied to the switching unit.

摘要： The present invention is featured, in the transmission of pixel (picture element) signals grouped into blocks defined in a series of pixel signals, by sending a control signal instead of said pixel signals when the pixel signals contained in a block are all white signals or sending pixel signals after modulation when black signals are present in said block thereby compressing the time required for transmission, also by selecting the maximum amplitude of said control signal larger than the maximum amplitude of said modulated pixel signals thereby enabling identification of said control signals from said pixel signals, and by sending, when the final black pixel signal in a black signal containing block is followed by consecutive white pixel signals, a control signal instead of such white pixel signals thereby achieving further compression of the transmission time.

摘要： The facsimile apparatus of the present invention is featured, by the functions of selecting transmission modes of picture signals according to a receiving mode informed of from a called party, for example, of transmitting picture signals representative of a picture reduced in size in case an original documents is larger in size than a recording sheet of paper of activating, in case a called machine is in a automatic reception mode, an acoustic output device incorporated in the called machine through a preliminary telephone talk function to request telephone talk with a called subscriber; and of maintaining a transmission line in its active state to call a called subscriber after transmission of picture signals in case a telephone talk is reserved or, otherwise, releasing the connection after transmission of picture signals in case a telephone talk is not reversed.The above-mentioned functions may be incorporated into a certain transmission protocol thereby accomplishing communication compatibility with other transmission-reception modes of picture signals.
