るＸＹプロツタ。 An XY plotter in which a writing block is moved in the X and Y directions by a pulse motor via a driving force transmission means, includes a detector fixedly disposed within the movement range of the writing block, and a detector that moves the writing block at the time of reset. The pulse motor is moved back and forth so that detection is performed by the detector, and the difference in steps of the pulse motor due to this reciprocating movement is set as a backlash correction value of the driving force transmission means, and the correction value is used when the pulse motor is driven in reverse. An XY plotter comprising a control means for controlling addition to a drive pulse.
