Recorder

Abstract

Abstract PURPOSE:To accelerate an image forming speed by sequentially skip-moving a plurality of recording heads over a region formed with an image by the heads. CONSTITUTION:Two recording heads 5A, 5B are integrally provided adjacent to each other near a drum 2 to be synchronously movable in parallel with the rotating axial direction of the drum 2 by a guide rail 6 for guiding the movement of the heads and a ball screw 8 driven by a head moving pulse motor 7. The feeding distance of the head 5 is determined on the basis of information output from an encoder 4. For example, when the fact that the drum 2 is rotated one revolution is detected by the encoder 4, the motor 7 is rotated for one pulse to synchronously move the heads 5A, 5B at a predetermined distance (for one line).
