To obtain a good quality image by reducing image noise due to feeding irregularity by a low-cost composition.

The recorder comprises a recording head 5 that records linearly on a recording sheet 10 and a speed reducing interlocking mechanism 15 having rotors 16 to 19 and a feed roller 11, and is equipped with a feeding means that feeds the recording sheet 10 in a direction perpendicular to the recording direction of the recording head 5. In such a case, the amount of feeding by an integral number of revolutions of optional toothed rotors 16 to 19 in the speed reducing interlocking mechanism 15 is matched with the amount of movement of the recording head 5 to the next recording position. Therefore, it is possible to obtain a good quality image without increasing costs involved by preventing an feeding error of optional toothed rotors 16 to 19 from affecting the feeding accuracy of the recording sheet 10.
