Abstract

PURPOSE:To obtain a copy of the normal original at the reception side in the retransmission system of the picture information which is suitably applied to the facsimile when the transmission fails, by performing a reading scan while sending adversely the original in the case of the failure of transmission and then transmitting the picture information obtained to the reception side again. CONSTITUTION:The case of the failure of transmission, the micro CPU20 delivers the step motor reverse driving data to the output port 25 to carry out the adverse transmission of the original, and at the same time starts the reading scan again. In this instant, the switch signal S1 is delivered by the multiplexer 18 from the CPU20 and via the input/ouput port 19, and thus the input/output end of the multiplexer 18 is switched until the sequence of connection becomes adverse for the input/output end as shown by the chaine line in the figure. Then the CPU20 stores successively the picture data delivered from the multiplexer 18 and from the final address in the line buffer region of the RAM22. Thus a copy of the normal original can be obtained at the reception side by transmitting again the picture information obtained to the reception side.
