<p>PURPOSE:To record a cross-marked positive image having a defective part, to facilitate registering, and to enhance operation efficiency by using a clock pulse in the principal scanning direction and a clock pulse in the secondary scanning direction as standards and turning off the output of a signal for recording a line image in a control circuit. CONSTITUTION:A clock pulse Pc, the reversed pulse of a signal Ck during a period for scanning an image region, one rotation pulse Pr, a recording head drive period signal Dr are each fed to terminals 31, 32, 37, 38, and recording signals H2 and V2 in the secondary scanning direction and the principal scanning direction are fed through AND circuits 33, 39, counters 34, 30, and monostable multivibrators 36, 42, directly or through shift register 43, 44 to OR circuits 45, 46, respectively, and a signal H2+V2 and a delayed signal H'2+V'2 are outputted. A magneta region signal tM and the signal H'+V' pass through an NAND circuit 49 and the signal H2 and V2 is directly inputted to an AND circuit 50, and when both signals are low in level, a signal dropped out by the line width is outputted 58. Therefore, a cross-marked positive image showing a defective part is recorded, thus facilitating registering.</p> |
