Abstract

PURPOSE: To ensure reproduction of a high-resolution picture by reading out the picture signals recorded on plural units of tracks at one time through plural units of heads and then converting these picture signals into a row of the time-series signals.
CONSTITUTION: Odd- and even-field picture signals S1 and S2 are controlled by control signal T1 sent from control circuit part 7 and then memorized in memory element part 8 and 9 in a speed equivalent to frequency f1 generated from clock source 12. These memorized signals are then transferred to register part 10 and 11 by control signal T2 provided for the blanking time of one scan line, and then read out from part 10 and 11 by control signal T3 and T4 with the speed equivalent to frequency f2 generated from clock source 13. These signals O1 and O2 are piled on each other, and the even- and odd-field signals are obtained in the form of interlaced signal O to drive the printer. Thus, the picture of one frame is recorded in sequence with every scanning line in the recording using, for example, the laser beam printer.
