Abstract: Apparatus for handling electronic components comprises a pick-up head 16 including a housing 74 and a tool comprising a elongated support member 80 (providing pick-up mechanism 84,98) mounted in the housing 74 for rotation about an axis D of the head 16 and for axial movement. A sleeve 122 and member 124 are rotatable with the tool but axially movable relative to the member 80. Clutch mechanism comprises a clutch pad 130 between a surface 132 of the housing 74 and a surface 128 of the member 124 and a spring 134 urging the surfaces 128, 132 and pad 130 together, locking the tool against rotation. Axial pressure on the sleeve 122 disengages the clutch permitting rotation of the tool which is effected through the sleeve 122. Several heads 16 mounted on a carousel 14 for movement from a pick-up station 26 through orientation stations 42, 48, to a placement station 50.
