PURPOSE:To simplify and reduce the size of electromagnet by facing the central portion of movable core fixed to the parts container side vertically against the central magnetic pole of E type electromagnet fixed to the static side while facing the opposite end sections of movable core horizontally against the opposite magnetic pole sections of E type electromagnet. CONSTITUTION:In an unit where a bowl 20 having springboard fixing block 25 secured to the underface is supported through plural springboards 31 arranged while inclining with equi-angular interval onto a base 21, movable cre 27 is secured through a fixing member 26 to the underface of said block 25. Many magnetic boards having projections 27a, 27b on a diagonal line while a slit in the center are laminated onto said core 27. While E-type electromagnet 28 is secured through fixing member 22 onto the base 21 to face the central magnetic pole secton 28c vertically against the central portion 27c of the movable core 27 while to face the opposite magnetic pole sections 28a, 28b horizontally against said projections 27a, 27b. |
