Abstract
The present invention relates to an ink jet printer in which drops of ink are jetted out onto a surface of a recording medium so as to record an image. The present invention is to obtain an economical ink jet printer in which a reaction force generated in the reciprocal motion of the ink jet head is simply canceled, and the ink jet printer is small and light, and less vibration is caused in the printer, and further it is possible to drive the printer with a small amount of drive energy. The ink jet printer comprises includes: a recording medium conveyance device for conveying a recording medium in the subsidiary direction; a plurality of ink jet heads in which a plurality of nozzles for jetting drops of ink to a surface of the recording medium are disposed, the ink jet heads being capable of moving in the primary scanning direction substantially perpendicular to the subsidiary scanning direction, the ink jet heads being arranged in the printer main body being aligned in the subsidiary scanning direction; and a head reciprocation drive device for reciprocating the ink jet heads in the primary scanning direction at phases different from each other.
