Abstract
A recording device capable of writing a character on a sheet of paper with a writing ball-point pen according to a set of character pattern data which is stored in a pattern memory, and erasing a written character with an erasing ball-point pen with reliability, by means of (1) modifying the set of character pattern data into a corresponding set of erasing pattern data which permits each of the components of an erasing path of the erasing pen to be shifted from the written character in a selected one of a first and a second direction which are normal to a first and a second reference line intersecting with each other, the set of erasing pattern data causing the component of the erasing path to be shifted in the first direction if a segment of the written character corresponding to the component is positioned nearer to the first reference line than the second, or to be shifted in the second direction if the segment is positioned nearer to the second reference line, and (2) controlling movements of the erasing pen and the sheet of paper, according to the modified set of erasing pattern data, to trace the written character along the erasing path.
