Abstract: The present invention relates to an ink jet recording apparatus having an ultraviolet irradiation head having a discharge tube. Solving means include a recording head that reciprocates along the surface of recording paper and discharges ultraviolet curable ink toward the recording paper, a discharge tube that moves together with the recording head and outputs ultraviolet light, and a movable plane reflecting mirror that switches between two light paths through which ultraviolet light from the discharge tube is applied in front of and behind the recording head in the reciprocation direction M. The discharge tube may include an elliptic reflecting mirror that converges output ultraviolet light toward the surface of the recording paper.

Abstract: A first current supplier supplies a first current to a first phase coil of a motor. A second current supplier supplies a second current to a second phase coil of the motor. A current selector selects a value of the first current and a value of the second current, so as to make constant at least one of a magnitude of a synthetic vector obtained by the selected value of the first current and the selected value of the second current at every microstep driving step of the motor, and an angular interval between synthetic vectors corresponding to adjacent microstep driving steps of the motor.
