<p>PURPOSE:To uniformize recording density by suppressing the falling of the temp. of a recording head by driving a recording head on a final line on the basis of reversal data when the recording of white data is continued. CONSTITUTION:In the recording part 102 controlled by the control part 101 of a facsimile device, a thermal head 13 being a line head is equipped with a shift resister 130 for inputting the serial recording data or shift block of one line, a latch circuit 131 and a heating element 132 consisting of heating resistors corresponding to one line. Recording is performed according to line data but, in this case, when the image data of a standard mode is decomposed into four lines of a superfine mode and all of data are white data, the signal outputted from a data forming part is set to an H-level and inversion data is transmitted to the thermal head 13 to correct the temp. of a heat generation inhibitor 132.</p> |
