ABSTRACT:
A facsimile device which stores the data of the incoming level of a training signal in the incoming mode, and judges this to be the starting point for receiving the picture signal when the incoming level after transferring the CFR signal is larger than the threshold level which is lower than the abovementioned stored incoming level by a predetermined value. The picture signal can be received with stability even when a circuit echo occurs.
