Abstract A magnetic fax system is disclosed. The system is adapted to receive information from a record medium and from a remote station, as well as to transmit information. When a record medium is provided, a magnetizing bar is used for magnetizing signals on the record medium. An endless travelling transfer magnetic sheet is provided for receiving the first magnetic signals from the record medium after they have been magnetized. A pair of coacting rollers press the endless transfer magnetic sheet to the record medium and an AC field is simultaneously supplied for transferring the magnetic signals to the endless magnetic sheet. A scanning device is provided downstream along the path of the endless magnetic sheet from the magnetizing region and by means of this device magnetic signals transmitted from a remote location may be transferred to the endless magnetic sheet and signals may be transmitted from the endless magnetic sheet to a remote location. The scanning device includes a recording head and a magnetic reading head which are positioned adjacent the endless sheet. An induction coil is coupled to the magnetic reading head and the recording head for transferring signals from the endless magnetic sheet and for transferring signals to the magnetic sheet. The endless sheet passes between a second set of coacting rollers which are located downstream from the scanning device, one roller extending into a supply of magnetic powder which has a resin coating thereon and the powder is thereby transferred to the endless sheet. The endless sheet next passes to a printing region which includes a third set of coacting rollers through which the endless sheet and a recording paper are simultaneously passed, the resin being thus transferred to the recording paper. A heating plate is positioned for melting the resin coating of the magnetic powder which has been transferred onto the recording paper. A demagnetizing system, such as a permanent magnet, is positioned along the path of the endless sheet for erasing the magnetic image.
