Abstract

PURPOSE: To obtain a higher demagnetization effect and to improve the efficiency in work by winding the demagnetizing coil around the reinforcing band made of magnetic material.
CONSTITUTION: The insulated coil support 16, the cross section of which is U- shaped, is provided on the relatively flat part of the reinforcing band 11 made of magnetic material so that the support surrounds the face panel. The insulated demagnetizing coil 10 of copper or alminum is winded around the support, the coil is fixed to the support with adhesives or resins, that is, the reinforcing band is made a core of the coil 10. In this way, a demagnetizing coil can be winded in a proper location with a greater demagnetization effect to improve the efficiency in work.
