<p>PROBLEM TO BE SOLVED: To accurately, easily, and efficiently form, from one surface side of an adhesive tape, a ditch by engraving ditches which are orthogonal each other and are not cut through to the other surface side on the supplied adhesive tape using a ditching means. SOLUTION: Ditch pitches P1 and P2 are formed on an adhesive tape by moving a slider along a guide rail in Y direction by a moving amount P3 between chips 12a of an electronic part 12 while moving it along the guide rail in X direction. Thus, a cutting blade is moved in X-Y direction based on a pre-input data. When the cutting blade is moved in Y direction, a cutting-blade rotary mechanism provided in a cutter holder rotates the cutting blade by 90 deg., cutting the adhesive tape in Y direction as well. Thus, ditches 30a are formed for die (square) or strip (rectangular) in the specified region of the adhesive tape.</p> |
