ABSTRACT

A plurality of vertically extending cylinders are formed in the interior of a
chuck body providing a chucking face on its lower surface. Pistons, in which
permanent magnets are embedded, are vertically movably provided in respective
ones of the cylinders. When compressed air is introduced into upper portions
of the cylinders, the pistons are downwardly displaced so that the permanent
magnets are relatively approached to the lower surface of the chuck body.
Thus, the chucking face is supplied with magnetic force exceeding a prescribed
level, to attract a holder holding electronic component chips, for example.
When compressed air is introduced into lower portions of the cylinders, on the
other hand, the pistons are upwardly displaced so that the permanent magnets
are relatively separated from the lower surface of the chuck body. Thus, the
chucking face is supplied with no magnetic force exceeding the prescribed
level, so that the holder is separated from the chuck body.
