Abstract

PURPOSE: To lower a lifting rod surely in a low noise as well as to make a needle pierceable by attaching a block, consisting of a superconductive material, to the lifting rod, and installing a needle driving part with at least a downing magnetic field generating coil which uses this block as a movable core.
CONSTITUTION: An electric current is made to flow into a downing magnetic field generating coil 22 and a upping magnetic field generating coil 24 alternately by a control signal out of a control circuit, and then a magnetic field is generated by these coils 22 and 24 at the current energizing side. A superconductive cylindrical block 20 attached to a lifting rod 16 is made to go up and down by this generated magnetic field. With this constitution, a needle 12 held on the lifting rod 16 free of detachment is made to go up and down whereby it is pierced through thick sewn cloth for sewing work.
