Abstract

PURPOSE:To simplify the delay circuit so as to attempt the reduction of cost for providing the delay circuit by modulating one printing signal to input into the delay circuit as a different frequency, and demodulating its output so as to derive the printing signal per line therefrom. CONSTITUTION:Printing signal C of cyan color is applied to ink jet head 1 as such, and after the printing signal M of magenta color has been delayed in the delay circuit 5 by the period of time when the point P1 on the recording paper moves to the point P2, the signal M is applied to the head 2 via filter 8. Printing signal Y of yellow color has been modulated in the modulation circuit 9 to different frequency, thereafter it is inputted into the delay circuit 5 where it is delayed by the time corresponding to the time till the point P1 moves to P2. Further it is delayed by the time till the point P1 moves to P3 in the delay circuit 6, thereafter it is demodulated in the demodulation circuit 10 to apply to the head 3. Thus the delay circuit can be simplified so as to reduce its cost.
