ABSTRACT:
A recording apparatus for recording graphs or other graphical representations, with relative movements between a writing instrument on a carriage which is moved by a carriage drive unit, and a sheet of paper which is fed by a paper feed unit in opposite directions perpendicular to the line of movements of the carriage. The writing instrument is moved between a recording position, and a non-recording position in which the writing instrument is spaced away from the paper. The apparatus comprises a controller for activating the paper feed unit and carriage drive unit to effect relative non-recording movements of the writing instrument and the paper with the writing instrument held in the non-recording position. The paths of the non-recording movements are determined based on input recording data so as to indicate a recording area in which the graphical representation is drawn by the writing instrument, whereby the operator can check dimensions and location of the recording area before the graphical representation is actually drawn on the paper.
