ABSTRACT:
To attract a workpiece with a limited contact region, e.g., a doughnut-shaped compact disc having a central circular hole, a skirt of a substantially arcuate attractor is held against an annular land extending around the central circular hole. Suction forces are applied through a plurality of suction holes surrounded by the skirt to attract the annular land for attracting and carrying the compact disc. A mini disc having an annular step along a peripheral region around a central hole thereof may stably be attracted and carried by an attractor having inner and outer annular contact members which axially project different distances to contact the peripheral region and an area, respectively, that is radially spaced from the peripheral region by the annular step.
