Abstract

PURPOSE:To shorten the recording time, by storing the signals for each group of the recording head and carrying out no recording action but rewriting the contents of the memory in case the signal to be recorded are not available among the stored signals. CONSTITUTION:When the picture signal is recorded by means of a recording element like a heat generating element, etc., the recording elements are divided into plural groups and the signal is applied to the recording element of the selected group. The quantized picture signals are supplied and stored by a line to a line memory 6 from an input signal 5. The signal corresponding to the group of the selected recording element is read out to an auxiliary memory 7 among the stored signals. At the same time, the presence or absence is discriminated for the black bit, i.e., the signal to be recorded by a JKFF9. When no black bit of a high level exists, the signal of the memory 7 is not transferred to a recording head driving circuit 15 but another group is selected for the recording element. Then the corresponding picture signal is transferred to the memory 7 from the memory 6.
