Abstract
ICs with leadframes can be efficiently transferred, stocked and positioned without the need for preparing jigs for each kind of IC. A cassette 4 accommodating a stack of ICs is inserted into a cassette space 35 and held in the center thereof. A moving table 9 is driven to move by a servomotor 21. A lifting member 67 of an IC lifting mechanism 60 raises the ICs in the cassette 4 from the bottom by an amount corresponding to the thickness of one IC at a time. A pulling-over device 70, which is disposed above the cassette space 35, centers the IC in both the lateral and longitudinal directions to thereby effect positioning.
