Abstract
A fax machine provided with an optical reader, a roller, a heat sensitive head for printing, a heat sensitive head press piece, a roller transmission mechanism, a heat sensitive head sustaining mechanism, and a steering clutch mechanism. As the fax machine receives a transmitting signal, the sustaining mechanism urges upwardly the heat sensitive head so that there is a substantial clearance between the heat sensitive head and the roller to ensure that the heat sensitive paper (the fax paper) is not rolled out when transmitting graphic information. As soon as the fax machine has received a reproducing or receiving signal, the steering clutch mechanism directly actuates the roller transmission mechanism so as to initiate the operation of reproducing or receiving graphic information while the heat sensitive head is not urged upwardly.
