Abstract

PURPOSE:To enable a device to be run without being influenced by a shutter inserting gap, by controlling a bearing force from a smaller gap length among gap lengths detected by a plurality of gap sensor sets arranged at front and rear positions in the advancing direction of a carrier near a core. CONSTITUTION:When a gap sensor 23a positioned in front in the advancing direction among a pair of gap sensors 23a, 23b is positioned under a shutter inserting gap 14, then a bearing force controlling unit 41 controls the exciting current of coils 33a, 33b so that a gap length for a magnetic attraction force and bearing gross weight due to a permanent magnet 31 which are made equal to each other on the basis of gap length detecting signal detected by the gap sensor 23b may be obtained. Besides, when the gap sensor 23b is positioned under the shutter inserting gap 14, then the exciting current of the coils 33a, 33b is controlled from the output of the gap sensor 23a.
