Patent ID: 7252189

Claim:
An alignment device for aligning orientation of laminated planar electrodes in laminated electronic parts, the laminated planar electrodes being mainly made from ferromagnetic material, the device comprising: a parts feeder providing a transportation passage on which a plurality of the laminated electronic parts are fed in a single row, the parts feeder comprising a bowl including a bottom section and a side wall section having an outer peripheral surface and an inner peripheral surface in which a spiral passage is formed, the bottom section and the spiral passage serving as the transportation passage; a magnetic field generation unit disposed outside of and beside the parts feeder to apply one of vertical and horizontal magnetic field lines to the laminated electronic parts running on the transportation passage, the magnetic field generation unit comprising a first electromagnet disposed radially outwardly of the spiral passage, and a second electromagnet disposed below the bowl; and means for selectively applying electricity to one of the first electromagnet and the second electromagnet.
