<p>PURPOSE:To eliminate the difference of printing density due to the difference of a block. CONSTITUTION:A data signal output means 12 outputting the data signal DATA related to a heating resistor 10A1, a strobe signal output means 16 dividing the heating resistor 10A1 into blocks 14A, 14B and outputting a strobe signal STBa alternately driving the blocks 14A, 14B and an AND gate 18A1 provided on the heating resistor 10A1 and subjecting the heating resistor 101A1 to ON/ OFF control on the basis of a data signal DATAa and the strobe signal STBa are provided. The strobe signal output means 16 changes the phase of the strobe signal STBa to the block 14A driven at first so as to equalize the drive times of the blocks 14A, 14B when the total times of the strobe signal STBa to the blocks 14A, 14B is changed.</p> |
