Abstract
A method for changing the direction of a cutting edge of a cutting plotter in order to align the cutting edge in the direction in which the initial portion of the desired cut will be made, prior to beginning a cut in the effective plotting area of a sheet mounted on a recording surface. By preliminarily aligning the cutting edge along the cutting direction, the cut can be made accurately along, for example, a straight line from the starting point of the cut. The method is performed with a cutting blade with a main edge directed diagonally upwardly from a cutting point, the cutting blade being rotatably supported in a holder for rotation around its axial center. The edge of the cutter can be aligned in a certain direction by first pressing the blade against a non-used portion of the sheet and moving the cutter therealong in a predetermined direction to cause rotation of the main edge of the cutter in the holder to align it in a first predetermined direction. Then, the cutter is raised from the marginal portion of the sheet, moved to a position over the cut-starting point of the effective plotting area of the sheet, and lowered such that the cutting point of the blade is pressed agai…
