Abstract
A pick-up head (10) of the apparatus has three alternative pick-up surfaces (24,34,64) formed respectively on a body (16), a first piston member (30), and a second piston member (60). The first piston member (30) is slidable in a cylinder (22a) formed in the body (16) and the second piston member (60) is slidable in a cylinder (48a) formed in the first piston member (30). The piston members (30,60) are movable between projecting positions and retracted positions. When both piston members are retracted, the surface (24) of the body (16) is used, when only the second piston member (60) is retracted, the surface (34) of the first piston member (30) is used, and, when neither piston member is retracted, the surface (64) of the second piston member (60) is used.
