Abstract
Disclosed is an apparatus for holding an electronic part including a rod coupled to a part-absorbing nozzle at one end thereof and coupled to a vacuum device at the other end portion thereof, the rod being axially movable. Also included is a sleeve member movable along the axis of the rod in response to the movement thereof. A pair of chucking jaws for chucking the electronic part are coupled through a transmission mechanism to the sleeve member. The transmission mechanism comprises a pair of curved levers each providing a connection between the chucking jaws and the sleeve member and a pair of guide members which are respectively engaged with the pair of chucking jaws and radially extend at right angles to the axis of the rod, and is arranged to allow the pair of chucking jaws to be moved at right angles to the axis of the rod member in opposite directions to each other in response to the movement of the sleeve member. The arrangement to move the chucking jaws at right angles with respect to the axis of the rod enables the electronic part to be accurately chucked by the chucking jaws irrespective of the variations of the size and configuration of the electronic part.
