PURPOSE:To offer a circuit configuration which can return to a normal operation at K parameter unit without stopping a facsimile system in case when an error occurs, by providing a pair of line memories and a picture data memory on a picture data output part of the delivery of a reload-processing circuit of a high speed facsimile whose processing time of 1 line is constant. CONSTITUTION:A pair of line memories 20, 22 in which a reloading data is written and read out alternately and by being replaced with each other, and a picture data memory 18 in which a read-out data of the line memory concerned is written and which has capacity being capable of storing a data of a plural line portion are provided on a data output part of the delivery of a reload- processing circuit 12, and if a bit error occurs in the course of transmission, the error is detected by the reload-processing circuit 12. When the error is detected, it is informed to an error processing circuit 14, switching of read-out and write of a line memory group 16 is stopped by a signal 30, and the line memory is fixed. Subsequently, a normal data of the other memory is sent repeatedly to the picture data memory 18, so that no blank part is made in recording. |
